Description

WINDING DEVICE FOR AN ELECTRIC CABLE
The present invention relates to a power cable winding device from which there can be taken desired lengths of electric lead or cable for connection between two coupling points, wherein the device includes two drums onto and from which electric lead can be wound and unwound respectively and which are fixedly mounted on a common rotatable drum shaft.
A winding device, or so-called winding winch (often porta- ble) , is used in many instances to obtain an electric connection between two coupling points. One coupling point may sometimes be stationary and the other movable, although the conditions may, of course, also be such that the location of the second coupling point, which is then also a fixed coupling point, may vary, i.e. it may have a fixed position and have the form of a wall socket fitted in a house or like dwelling.
Several different types of devices for producing a desired connection between two coupling points are known to the art. For instance, there are known extendable helically wound leads of the type used as telephone cords, dictaphone cords and like cords or leads. Power leads, or cords, of this construction are best suited for shorter extendable lengths and have a certain tendency to lengthen with time, as the elasticity of the material used wears off.
Another type of lead-extending devices uses rings which are slidably mounted on a fixed rod, line or the like, with the lead fixed in the rings in generally mutually spaced rela¬ tionship, so that when extended the lead will not sag between the rings. A construction of this kind extends in a given predetermined direction, but has limited lateral connection possibilities.
It is also known to use a winding device of the type men- tioned in the introduction in conjunction with rotary motors. In this regard, commutating devices are often used, sliding contacts making possible connection to rotary parts. An arrangement of this kind, however, can be the cause of electrical disturbances and interference in equipment connected thereto, and is also subjected to high mechanical stresses and strains.
The object of the present invention is to provide a winding device of the kind defined in the introduction which is small and light in weight and of simple operation and suited for use in many different fields. This object is achieved in accordance with the invention with a winding device which is mainly characterized in that each of the two winding drums, which are mounted immediately adjacent one another on the drum shaft, have side walls of which one is common to the two drums and forms an intermediate wall, and in that the diameter of one drum is smaller than the diameter of the other drum and that the mantle surface of said one drum forms part of the mantle surface of the drum shaft.
The invention will now be described in more detail with reference to the accompanying drawing, which is a cross- sectional front view of an inventive winding device as seen from above.
The winding device illustrated in the drawing comprises two winding drums 10, 12 which are fixedly mounted on a common drum shaft 14. As will be seen, the two drums 10, 12 are used together with one single electric lead or cable 16. The cable 16 may, however, have different forms in relation to the two drums 10, 12, wherein the cable may, of course, also be spliced or otherwise joined therebetween, such that one cable part 18 will be thicker than the other cable part 20, as will also be seen from the drawing. It will be noted that the illustrated electric cable 16 is shown simply drawn between the two drums 10, 12 and thus not wound onto any of said drums.
In the case of the illustrated embodiment, the winding drums 10, 12 fixedly mounted on the drum shaft 14 differ markedly from one another with regard to drum width and drum diameter. Thus, the winding drum shown on the right in the drawing is much wider than the drum shown on the left and has a much larger diameter. Both winding drums 10, 12 have side walls 22, 24, 26, which are intended to prevent cable 16 wound onto a drum from sliding off. In the illustrated case, one wall 24 is common to both winding drums 10, 12.
The ratio between the diameter of the drum 12 of smaller diameter and the diameter of the drum 10 of larger diameter is preferably less than two-thirds
The drum 10 of larger diameter is provided with a cylindrical winding part 28 mounted between the wall-s 22, 24 and the electric cable 16 extends from outside the drum 10 through a passage which enables the cable to be connected to the interior of the drum shaft 14, which in the illustrated case is a hollow shaft. To this end, corresponding holes 30, 32 are provided in the winding part 28 and the drum shaft 14. The cable 16, or lead, then passes through the drum shaft 14 to the outside of the other drum 12, via a corresponding further hole 34. In the illustrated case, the drum shaft 14 forms the winding part of the second winding drum 12.
When using the novel winding device, ten turns of cable may be initially wound onto the larger drum 10, and five turns wound onto the smaller drum 12. In this regard, the same winding direction is used for both drums 10, 12. If ten turns are now unwound from the larger drum 10, five turns will be unwound simultaneously from the small drum 12 and five turns will again be wound on the latter, although in the opposite winding direction. When winding the ten turns onto the large drum 10, five turns are unwound on the small drum 12 and a further five turns are again wound onto the small drum 12 in the opposite direction.
The above winding example shows that the novel winding device, which may be relatively small in size, provides an elegant method of enabling a cable to be reeled-on and reeled-off respective drums so as to enable the cable to be connected between two connection points (not shown) in the way intended by the invention.
Those locations in the novel winding device where the electric cable or lead is subjected to the greatest strain when being unwound from and wound onto the device are found in the vicinity of the peripheral surfaces of the two drums at the place where the electric cable 16 runs into respective holes 30, 34. It may therefore be suitable to provide protective means in order to dampen or relieve the strain. This can be achieved either by providing the electric cable with a damping sleeve or by configuring the hole openings so that the cable will bend gently as it passes therethrough. Such arrangements have not been shown, however.
It will be understood that the described device can be modified within the scope of the invention. For instance, it is not necessary to draw the electric cable inside a hollow shaft. Instead, the cable may run along the outer surface of the shaft and then pass through corresponding openings in the side wall or walls of the winding drum or winding drums respectively.
The side walls 24, 26 of the drum 12 are generally circular in shape and coaxial with the shaft 14. A stationary hood 40 has two walls 44, 46 which extend towards the walls 24, 26, wherein the radial gaps between the side walls and the hood walls are sufficiently small to prevent the cable 20 passing therethrough. The hood 40 is delimited outwards by an end wall 47 which prevents the cable 20 from falling freely of the drum in a radial direction.
The radially outer end-part of the cable 20 on the drum 12 extends through a generally axially directed opening 48 through one of the hood walls 44, 46 in the proximity of the end wall 47.
The two drums 10, 12 are suitably mounted to rotate about a common geometric axis. The illustrated drum shaft 14 has a constant outer diameter along its length, although it will be obvious that it may have different diameters in the two drums, wherein the diameter of the drum shaft in the drum 12 is suitably adapted to the requirement of a smallest diameter for the drum 12. It is also possible to change, e.g., the diameter of the drum 12 by fitting a diameter enlarging annulus between the side walls 24, 26 onto the shaft 14, either releasably or permanently, said annulus conveniently having a radial opening for receiving the cable when the shaft 14 is hollow and accommodates the cable.
The hood 40 is shown carried by a stand 49 which also carries the drum shaft bearings 51, 54.
Although not shown, the inventive device may be fitted into a vacuum cleaner
