Description

The invention relates to a floor nozzle for a floor care appliance and to a method for producing a floor nozzle for a floor care appliance

In private households as well as in industry, floor care appliances, such as vacuum cleaners, are used to clean surfaces such as textile floor coverings and smooth floors. In this case, a floor nozzle of the floor care device on a floor surface is continuously pushed back and forth to pick up dust. A Staubaufnahmeeffektivität the floor care device also depends on a design of the floor nozzle.

The EP 2 152 135 B1 describes a nozzle for a floor care device, in which a trained by a pivotable lip so-called suction mouth behind the suction port of the nozzle optimally adjusts to the conditions that occur when pushing and pulling the nozzle.

The invention has for its object to provide an improved floor nozzle for a floor care device and an improved method for producing a floor nozzle for a floor care device.

According to the invention, this problem is solved by a floor nozzle for a floor care appliance and a method for producing a floor nozzle for a floor care appliance having the features of the main claims. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

With an arrangement of a pivotable suction lip on a side facing away from a connection piece of a floor nozzle end of a suction mouth of the floor nozzle, the dust absorption efficiency of the floor nozzle - especially on carpets - be increased advantageously, so that good performance classes can be achieved even at low recording powers.

According to the approach presented here, the same or at least approximately equal forces in the direction of the floor covering can be exerted on the front and the rear Saugmundkante on a flooring to be cleaned in a use of the proposed floor nozzle having floor care device when pushing and pulling the floor nozzle. Since with the presented approach, the suction mouth edge in front of the suction mouth on flexible can respond to changing conditions of the flooring, the floor nozzle against the flooring can be optimally positioned to achieve good dust absorption values.

A floor nozzle for a floor care apparatus for cleaning floor surfaces, wherein the floor nozzle has a sliding sole in which an opening in the form of a suction mouth is arranged, from which leads to a nozzle of the floor nozzle for receiving a suction pipe of the floor care device, an intake passage, has the following feature :

• a suction mouth lip which delimits an end of the suction mouth facing away from the connecting piece, wherein the suction mouth lip is designed to be pivotable about an axis extending transversely to a pushing movement of the floor nozzle.

Through one or more of the presented suction mouth lips or suction mouth lips, a height adjustment of the suction mouth to a carpet or other floor covering can be ensured during forward and backward strokes of the floor nozzle. As a result, the dust-collecting efficiency can be advantageously increased. In principle, this can also be solved by a double joint. However, the solution proposed herein with the suction mouth lips can cause higher dust pickup values at the same time lower sliding forces and is cheaper to implement. Another advantage is that with a switchable for hard floor cleaning floor nozzle, the bristle strip can only serve as a support function. The seal to the hard floor can be realized by the two suction mouth lips. Especially when cleaning from scratches such high values can be achieved. Since the lips are flexible and can dodge unevenness, as a further advantage of the concept presented here, the ground clearance can be kept low.

The floor care appliance may be a vacuum cleaner. The vacuum cleaner can be designed to generate a negative pressure by means of a blower, with which dust and dirt can be absorbed by the floor surface via the floor nozzle guided in the pushing movement over a floor surface to be cleaned. The push movement can be understood to mean a forward and backward movement of the floor nozzle over the floor surface by an operator of the floor care appliance. For example, the operator may handle a handle of the floor care appliance connected to the suction tube.

A body of the floor care appliance may have a dust receiving chamber in which the dust received via the floor nozzle can be collected, for example, in a dust bag. The floor nozzle can be connected by means of the connecting piece via the suction pipe with the body. About the connection piece, the floor nozzle of an operator of the ground care device optionally coupled to the suction pipe and be removed from this again.

The floor nozzle may have, for example, a rectangular housing which may have the connecting piece on one of two opposite long sides. The sliding sole with the suction mouth can be located on one of the underside of the floor nozzle facing the floor surface to be cleaned. The sliding sole may be designed to slide in the pushing movement of the floor nozzle over the floor covering to be cleaned and to move the suction opening forming a suction opening for the dust to be absorbed to different areas of the floor covering.

The suction mouth may also have a rectangular shape. The dust collected from the bottom surface via the suction mouth can be transported through the suction channel and the suction tube into the dust receiving chamber of the floor care device. The suction mouth lip may be understood to mean a fastened or attachable element on the underside of the floor nozzle, the free end of which may be designed to pivot back and forth about the axis when in contact with the floor surface in accordance with the thrust movement. The suction mouth lip may be elongated and extend parallel to the long sides of the rectangular housing of the floor nozzle.

The floor surface may be covered by a textile floor covering such as a carpet or carpet or by a hard floor such. As a wood parquet, laminate or PVC flooring are formed.

According to an embodiment of the floor nozzle, the suction mouth lip may have a first suction mouth lip area, a second suction mouth lip area and a third suction mouth lip area. Here, the second suction mouth lip region may connect the first suction mouth lip region to the third suction mouth lip region and be characterized by greater flexibility than the first suction mouth lip region and the third suction mouth lip region. Specifically, the first suction mouth lip portion may be fixedly connected to the floor nozzle, the third suction mouth lip portion may be formed to contact a floor surface to be cleaned, and the second suction mouth lip portion may be formed to pivot around the axis in response to friction of the suction mouth lip with the bottom surface. With this embodiment, a robust attachment of the suction lip to the floor nozzle, a smooth pivoting movement of the suction lip and an optimally aggressive treatment of the floor surface to be cleaned can be ensured by the suction lip simultaneously advantageous.

In particular, in a position of rest on the side of the suction mouth, the suction mouth lip can project beyond the sliding sole from the floor nozzle. Under the rest position, a position of the suction lip can be understood in the absence of contacting a floor surface through the floor nozzle. In the rest position, the suction lip may for example be aligned perpendicular or approximately perpendicular to the floor surface to be cleaned. Thus, it can be ensured without further ado that the suction lip during the cleaning process can act sufficiently strong on the surface to be cleaned.

According to a further embodiment, the sliding sole can form a first stop element for limiting a swing deflection of the suction mouth lip in a first pivoting direction and / or a second stop element for limiting a pivoting deflection of the suction mouth lip in a second pivoting direction opposite to the first pivoting direction. In this case, the first stop element viewed from the connection piece of the suction lip may be upstream and the second stop member viewed from the connection piece from the suction mouth lip downstream. This can be prevented in a simple manner that the suction lip is moved too far out of its field of action due to the thrust movement.

In particular, the first stop element can provide a first stop surface for the suction lip and additionally or alternatively provide the second stop element, a second stop surface for the suction lip. In a rest position of the suction mouth lip, the first stop surface may extend substantially parallel to the suction mouth lip and the second stop surface substantially at an angle in the range of 45 degrees to 90 degrees, in particular at an angle of 70 degrees, to the suction mouth lip. Thus, when carrying out the pushing movement, a simultaneous advantageous up and down movement of the floor nozzle relative to the floor covering can be realized, by means of which a more intensive treatment of the floor area promoting the dust absorption can be achieved.

According to one embodiment, the floor nozzle may have a further suction mouth lip. The further suction mouth lip may define an end of the suction mouth facing the connection piece and may be designed to be pivotable about a further axis extending transversely to the pushing movement of the floor nozzle. With the additional suction lip, the dust holding capacity of the floor nozzle can be advantageously increased.

With the further suction mouth lip, the sliding sole can form a third stop element for limiting a swing deflection of the further suction mouth lip in the first pivoting direction and additionally or alternatively a fourth stop element for limiting a pivoting deflection of the further suction mouth lip in the second pivoting direction. In this case, the third stop element viewed from the connection piece be further upstream of the further suction lip and the fourth stop element viewed from the connecting piece of the further suction lip to be downstream. This can be prevented in a simple manner, as in the suction lip, that the other suction lip due to the pushing movement is moved too far out of its field of action.

Accordingly, the third stop element can provide a third stop surface for the further suction mouth lip and / or the fourth stop element can provide a fourth stop surface for the further suction mouth lip. In a rest position of the further suction mouth lip, the third stop surface can essentially be at an angle in the range of 45 degrees to 90 degrees, in particular at an angle of 70 degrees, to the further suction mouth lip and the fourth stop surface extend substantially parallel to the further suction mouth lip. With this embodiment, the already explained advantageous up and down movement of the floor nozzle relative to the floor covering can be advantageously stabilized.

According to a further embodiment, the first stop element with respect to a connecting line between a arranged for movement on a bottom surface of the floor nozzle movement element and a corner of the other suction lip when the other suction lip on the third stop element by 0.5 to 4 millimeters in the direction of an interior of Stand back floor nozzle. As arranged on the floor nozzle moving element comes one or more rollers or skids in question.

Also, the suction lip may protrude in a rest position relative to the connecting line by 0.5 millimeters to 4 millimeters from the floor nozzle.

With these length specifications for the first stop element or the suction lip, it can be achieved that the suction lip protrudes just as far from an underside of the floor nozzle and is properly supported, that in the pushing movement the flexible lower edge of the suction lip can optimally process the floor surface to be cleaned, for example by bending the fibers of a carpet or carpet.

For the same reason, according to a further embodiment, the fourth stop element with respect to a further connecting line between a arranged for movement on a bottom surface of the floor nozzle movement element and an end point of the suction lip when the suction lip on the first stop element by 0.5 millimeters to 4 millimeters stand back towards an interior of the floor nozzle.

A method of making a floor nozzle for a floor care floor cleaning implement comprises the following steps:

Providing a floor nozzle body with a sliding sole, in which an opening in the form of a suction mouth is arranged, from which leads to a connection piece of the floor nozzle for receiving a suction pipe of the floor care device, an intake duct; and

Arranging a suction mouth lip on an end of the suction mouth facing away from the connecting piece, so that the suction mouth lip pivotally limits the end of the suction mouth about an axis running transversely to a pushing movement of the floor nozzle.

Also by this embodiment of the invention in the form of a method, the object underlying the invention can be solved quickly and efficiently.

Identical or functionally similar elements can be designated in the different figures by the same or similar reference numerals, description of these elements will be omitted in the other figures.

FIG. 1 shows a schematic diagram of a floor care device 100 according to an embodiment of the present invention. The floor care appliance 100 is Here is an electrically powered vacuum cleaner with a body 102, from which a hose 104 opens into a suction pipe 106, at the far end of the corpus a floor nozzle 108 is infected. For securely connecting the floor nozzle 108 with the suction tube 106, the floor nozzle 108 has a connection piece 110, into which the far end of the suction tube 106 can be snapped. An operator of the vacuum cleaner 100 may grasp it at a handle 112 formed at a proximal end of the suction tube 106 and thus push the floor nozzle 108 back and forth across a bottom surface 116 in a push motion 114 indicated by a double arrow in the illustration to clean it.

The floor nozzle 108 here has a rectangular shape, with opposite long sides of the rectangle transverse to the in Fig. 1 indicated thrust movement 114 extend. Thus, with each stroke of the pushing movement 114, the widest possible path of the bottom surface 116 can be traveled to pick up dust and dirt. For ease of pushing or pulling the floor nozzle 108 on the floor surface 116, the floor nozzle 108 may include rollers.

An electric cable 118 is used to operate a fan (not shown) of the vacuum cleaner 100 which is integrated into the body 102 and by means of which a negative pressure is generated. So is about a (in Fig. 1 Not shown) suction mouth with specially designed suction lips in the floor nozzle 108 dust and dirt particularly effectively absorbed by the bottom surface 116. The sucked dust is conveyed via the suction tube 106 and the tube 104 in the body 102 and spent there, for example, in an exchangeable dust bag.

FIG. 2 shows in a sectional view of a section of the floor nozzle 108 presented herein Fig. 1 , The illustration shows schematically, but in detail, a construction according to the invention of a dust receiving area 200 of the floor nozzle 108. The dust receiving area 200 is on one of the bottom surface to be cleaned facing the bottom nozzle 108, ie a bottom of the floor nozzle 108, on a bottom plate of the floor nozzle, not shown here 108 arranged.

The dust receiving area 200 has a sliding sole 202, which is designed to slide in the pushing movement 114 of the floor nozzle 108 on the floor surface to be cleaned. In the sliding sole 202 is an opening in the form of a so-called suction mouth 204 of the floor nozzle 108. From the suction mouth 204, an intake passage 205 leads to the connecting piece 110 of the floor nozzle 108. With a movement of the suction mouth 204 on dust and dirt particles on the floor this due to the above-mentioned, generated by the blower of the vacuum cleaner, through the suction port 204 and pulled the intake passage 205 in the coupled via the connecting piece 110 with the floor nozzle 108 intake manifold, the in Fig. 2 not shown.

At the in Fig. 2 shown embodiment of the floor nozzle 108, the suction port 204 is limited at a side facing away from the connecting piece 110 end 206 of a suction lip 208. At the in Fig. 2 Suction lip lip 208, shown in cross-section, is an elongated member extending parallel to the long sides of the floor nozzle 108 and made of plastic, for example. The suction mouth lip 208 is attached to the sliding sole 202 and is in an in Fig. 2 shown rest position on the side of the suction mouth 204 on the sliding sole 202 down from the floor nozzle 108 before.

At the in Fig. 2 In the embodiment shown, the suction mouth lip 208 is composed of a first suction mouth lip region 210, a second suction mouth lip region 212 and a third suction mouth lip region 214. With the first suction mouth lip region 210, the suction mouth lip 208 is firmly connected to the floor nozzle 108. At the in Fig. 2 In the embodiment shown, the first suction mouth lip region 210 is inserted in a suitably shaped recess or depression of the sliding sole 202 for this purpose.

The second suction mouth lip region 212 is configured to connect the first suction mouth lip region 210 to the third suction mouth lip region 214 and is characterized by a higher flexibility compared to the two other suction mouth lip regions 210, 214. This can be achieved, for example, by the use of a suitable material in the production of the second suction mouth lip region 212. At the in Fig. 2 In the embodiment shown, the higher flexibility of the second suction mouth lip region 212 is at least partially achieved in that the second suction mouth lip region 212 has a substantially smaller cross section than the first suction mouth lip region 210 and the third suction mouth lip region 214. The third suction mouth lip portion 214 is configured to manipulate the floor covering upon retraction and retraction of the floor nozzle 108 on a floor surface by an operator of the floor nozzle 108 to facilitate and enhance dust and dirt pickup.

So that this processing of the floor covering can be carried out as effectively as possible, the suction mouth lip 208 is pivotable about an axis 216 extending transversely to the pushing movement 114 of the floor nozzle 108. Concretely, when the suction mouth lip 208 is rubbed with a bottom surface to be cleaned, the second suction mouth lip region 212 equipped with greater flexibility pivots about the axis 216. Thus, the third suction mouth lip region 214 connected to the second suction mouth lip region 212 is slid over the bottom surface in the sense of a pendulum motion 114 or pulled.

In order to limit the pivoting movement of the suction mouth lip 208 about the axis 216, the floor nozzle 108 has a first stop element 218 and a second stop element 220. At the in Fig. 2 In the embodiment shown, the first stop element 218 is designed in the form of a wall which at least partially delimits the suction mouth 204, and the second stop element 220 is designed as a notch formed in the sliding sole 202 with an oblique course. When viewed from the connection piece 110, the first stop element 218 is arranged upstream of the suction mouth lip 208 and the second stop element 220 is positioned downstream of the suction mouth lip 208. The first stop member 218 provides first stop surface 222 for limiting a swing deflection of the suction mouth lip 208 in a first pivoting direction for the suction lip 208. The second stop member 220 provides a second stop surface 224 for limiting a swing deflection of the suction mouth lip 208 in a second pivot direction opposite to the first pivot direction.

In the illustration in Fig. 2 the suction mouth lip 208 is shown in a rest position, which assumes this due to integrated in the suction lip 208 restoring forces when the floor nozzle 108 contacted no surface. As the illustration shows, the suction lip lip 208 is in its rest position substantially perpendicular with respect to the pushing movement 114. Accordingly, runs in the rest position of the suction lip 208 at the in Fig. 2 1, the first stop surface 222 is parallel to the suction mouth lip 208 and the tapered second stop surface 224 is at an angle of 70 degrees to the suction mouth lip 208.

In alternative embodiments, the angle of the second stop surface 224 to the suction mouth lip 208 at rest may be in a range of 45 degrees to 90 degrees.

FIG. 3 shows in a further schematic sectional view of a section of a further embodiment of the floor nozzle 108 presented herein Fig. 1 , Shown is a variant of the dust receiving area 200 of the floor nozzle 108. The dust receiving area 200 is also arranged here on an underside of the floor nozzle 108 on one of the bottom surface to be cleaned facing side of a bottom plate 300 of the floor nozzle 108. In the illustration in Fig. 3 the bottom plate 300 is indicated by a dashed line. In the Fig. 3 shown exemplary floor nozzle 108 already has the Fig. 2 presented suction mouth lip 208 on.

In the illustration in Fig. 3 the suction mouth lip 208 is shown in a working position characterized by friction of the suction mouth lip 208 with a floor covering, here applied to the first stop element 218. In the illustration in Fig. 3 For example, the bottom nozzle 108 is shown moving in a first component of the pushing motion 114, namely in a thrust direction 302, which is shown in FIG Fig. 3 by means of a directional arrow is marked. In the thrust direction 302, the operator of the floor nozzle 108 moves them away from them in a quasi-forward direction.

Since the pivoting movement of the suction lip lip 208 takes place in response to the friction of the suction mouth lip 208 with the floor covering, the suction mouth lip 208 pivots counter to a currently executed component of the pushing movement 114. Accordingly, the suction mouth lip 208 pivots at the in Fig. 3 shown in a current direction of thrust 302 in one - by means of one of the thrust direction 302 opposite arrow marked in the illustration - first pivot direction 304. The pivoting movement of the suction lip 208 is limited by the in Fig. 3 shown stop the suction mouth lip 208 on the first stop surface 222nd

At the in Fig. 3 shown embodiment of the floor nozzle 108, a further suction mouth lip 306 is provided. The further suction mouth lip 306 is arranged on or in the sliding sole 202 in such a way that it delimits an end 307 of the suction mouth 204 facing the connection nozzle of the floor nozzle 108. At the in Fig. 3 shown embodiment of the floor nozzle 108, the connecting piece is in turn located right hand with respect to the suction mouth 204, but not shown in the illustration. The further suction mouth lip 306 has an identical construction to the suction lip lip 208 and is arranged pivotably about a transversely to the pushing movement 114 of the floor nozzle 108 extending further axis 308 in the sliding sole 202.

To limit a pivoting movement of the further suction mouth lip 306 about the further axis 308, the floor nozzle 108 has a third stop element 310 and a fourth stop element 312. At the in Fig. 3 In the embodiment shown, the third stop element 310 is mirror-inverted to the second stop element 220 as an incision formed obliquely in the sliding sole 202 and the fourth stop element 312 is mirror-inverted to the first stop element 218 in the form of a wall at least partially delimiting the suction mouth 204. Viewed from a position of the connecting piece, the third stop element 310 is disposed in front of the further suction mouth lip 306 and the fourth stop element 312 is disposed downstream of the further suction mouth lip 306.

The third stopper member 310 provides third stopper surface 314 for limiting a swing stroke of the further suction mouth lip 306 in the first pivoting direction 304. The fourth stop member 312 provides a fourth stop surface 316 for limiting a swing deflection of the further suction mouth lip 306 in a second pivot direction opposite to the first pivot direction 304. In an in Fig. 3 Not shown rest position of the other suction mouth lip 306 runs the third Stop surface 314 at an angle of 70 degrees to the other suction mouth lip 306 and the fourth stop surface 316 parallel to the other suction mouth lip 306th

In alternative embodiments, the angle of the third abutment surface 314 to the further suction mouth lip 306 in the rest position may be in a range of 45 degrees to 90 degrees.

Due to the in Fig. 3 illustrated movement of the floor nozzle 108 in the thrust direction 302, the further suction mouth lip 306 is shown in a marked by friction of the other suction mouth lip 306 with a floor work position in which it is applied to limit its pivotal movement of the third stop member 310. Like the pivotable suction mouth lip 208, the further pivotable suction mouth lip 306 also consists of two components. The first suction mouth lip portion 210, which is for fixing in the sliding sole 202, and the third suction mouth lip portion 214, which contacts the floor cloth, are formed of a hard material. The middle part, ie the second suction mouth lip area 212, serves as a joint and consists of the in Fig. 3 shown embodiment of a soft component.

In particular, in the in Fig. 3 shown embodiment of the floor nozzle 108, the first stop element 218 so dimensioned that it is opposite to a in Fig. 3 not shown connecting line between a trained for sliding on the bottom surface sliding surface 318 of the sole plate 202 and an end point 320 of the other suction lip 306 when conditioning the other Saugmundlippe 306 on the third stop element 310 by 0.5 millimeters to 4 millimeters toward an interior of the floor nozzle 108th back is. The suction mouth lip 208 is dimensioned so that it protrudes in its rest position relative to this connecting line by 0.5 millimeters to 4 millimeters from the floor nozzle 108.

Furthermore, the fourth stop element 312 is dimensioned such that it faces a further straight line between the sliding surface 318 of the sliding sole 202 and an end point 322 of the suction lip 208 when the suction lip 208 abuts the first stop element 218 by 0.5 millimeters to 4 millimeters in the direction of a Interior of the floor nozzle 108 stands back. Opposite this further connecting straight line, the further suction mouth lip 306 protrudes in its rest position by 0.5 millimeter to 4 millimeters from the floor nozzle 108.

The others - in the illustration in Fig. 3 rear - Saugmundkante or Saugmundlippe 306 of in Fig. 3 shown suction attachment is designed so flexible that it can pivot on the floor covering in the forward stroke of the floor nozzle 108 in the thrust direction 302 by the friction. An installation space behind the further suction mouth lip 306 is such that they tilt up to an angle of approximately 70 degrees to the vertical leaves. An in Fig. 3 not shown rear thread lifter of the floor nozzle 108 is located - in the forward stroke direction 302 - behind the swung another flexible suction lip 306th

In front of the rear suction mouth edge 306 is the fourth stop element 312, a further, however, rigid edge, which according to embodiments about 0.5 to 4 millimeters to a degree of connection between the - in the illustration in Fig. 3 front - suction mouth 208 and a in Fig. 3 not shown impeller of the floor nozzle 108 is behind. According to one embodiment, the flexible edge 306 is 0.5 to 4 millimeters above these levels. In a forward stroke 302 opposite backward stroke of the suction attachment, the flexible edge 306 applies to the rigid edge 312 and thus is perpendicular to the floor.

The front suction mouth edge or suction lip 208 of the in Fig. 3 shown Saugvorsatzes is designed so flexible that it can pivot on the floor covering up to the limit provided by the first stop surface 222 backward during the forward stroke 302 by the friction. Behind the front suction mouth edge 208 stands with the first stop element 218, a rigid edge, which according to one embodiment, about 0.5 to 4 millimeters between a connection degrees between the rear suction mouth edge 306 in pushing position and the support skid 202 and a in Fig. 3 not shown impeller of the floor nozzle 108 is behind.

The flexible edge 208 is according to an embodiment over 0.5 to 4 millimeters to these degrees. During the forward stroke 302 of the suction attachment, the flexible edge 208 abuts against the rigid edge 218 and thus is perpendicular to the floor. The space in front of the edge 208 is such that it can be tilted on the return stroke to an angle of approximately 70 ° to the vertical. An in Fig. 3 not shown front thread lifter of the floor nozzle 108 is located in the forward stroke direction 302 in front of the swung-flexible suction mouth edge 208th

The portion 214 of the flexible suction mouth edges 208, 306, which makes contact with the floor covering, is made of a hard material. The middle hinge portion 212 may consist of a hinge according to embodiments or preferably of a flexible rubber material.

FIGS. 4 and 5 show a functionality of an embodiment of the herein proposed floor nozzle 108 based on two components of the pushing movement 114. Shown is a respective pivotal movement of the suction mouth lips 208, 306 in response to friction with the bottom surface 116, on which the floor nozzle 108 is pushed or pulled.

Fig. 4 shows in a schematic cross-sectional view a position of the suction mouth lips 208, 306 with a movement of the floor nozzle 108 in the thrust direction 302 as the first component of the pushing movement 114. As the illustration shows, due to the friction with the bottom surface 116, the suction mouth lip 208 against the thrust direction 302 pivoted in the first pivoting direction 304 until it comes to rest on the first stop element 218. The further suction mouth lip 306 is pivoted in the first pivot direction 304 until it comes to rest on the third stop element 310.

Fig. 5 shows in a further schematic cross-sectional view of a position of the suction mouth lips 208, 306 in a movement of the floor nozzle 108 in a second component of the pushing movement 114. The second component of the pushing movement 114 is a direction opposite to the thrust direction 500, which in the illustration in Fig. 5 is marked by a directional arrow. In the pulling direction 500, the floor nozzle 108 is moved when an operator of a floor care appliance having the floor nozzle 108 pulls the floor nozzle 108 toward, ie, back.
