Definitions
- the present invention relates to the general technical field of domestic suction devices and relates to telescopic suction devices as well as vacuum cleaners comprising such devices.
- Patent application US 3 244 437 describes a telescopic assembly for a vacuum cleaner comprising an inner tube, an outer tube, a seal for sealing between the inner tube and the outer tube, and an elastic lock capable of blocking the two tubes in a position chosen between a position in which the inner tube is extended to the maximum and a position in which the inner tube is retracted to the maximum.
- the object of the invention therefore aims to remedy these various drawbacks and to provide a device offering a storage position and a working position which is simple to use and particularly of construction economic.
- a telescopic device for a vacuum cleaner comprising an inner tube and an outer tube, the inner tube being able to slide in the outer tube between a retracted position and an extended position, an annular seal, provided to ensure a seal between the inner tube and the outer tube, and a latch mounted on the outer tube, intended to lock the two tubes in at least one position, characterized in that the seal cooperates with a ring for sealing the device when the outer tube is locked in the extended position on the inner tube by means of the latch, and the seal offers no contact with one of the walls of the tube, thus providing an annular space with said wall, when the inner tube occupies at least one intermediate position, and preferably the majority of the intermediate positions, between the retracted position e and the output position.
- This arrangement avoids stressing the seal against the walls of a tube and thus ensures a better longevity of the device.
- the device is sealed only in the extended position.
- This arrangement also makes it possible to use for the tubes materials having high coefficients of friction, such as plastics, and thus to obtain an inexpensive device, and moreover, lighter than a device produced with tubes in metal.
- This arrangement avoids overheating during a rapid displacement of one of the tubes relative to the other, and facilitates for the user the displacement of the two tubes because the friction is very greatly minimized, no seal rubbing on the entire length of one of the tubes.
- This arrangement also makes it possible to accept better tolerances for ovalization of the tubes, which is favorable to the use of plastics for the tubes.
- the inner tube has an outer wall of cylindrical shape comprising a first guide means cooperating with a second guide means mounted in the outer tube.
- the inner tube has one end having an outer conical chamfer capable of cooperating with an inner conical chamfer formed in the outer tube, when the inner tube is in the retracted position in the outer tube.
- This arrangement also ensures a seal when the device is in the retracted position.
- the retracted position of said device corresponding to the storage position, then also corresponds to a position of secondary use, the extended position of said device then corresponding to the position of preferential use.
- the chamfers are provided to ensure a non-blocking stop.
- This arrangement makes it possible to prevent the almost irreversible tightening of one tube on the other, for example when the user retracts the inner tube into the outer tube by exerting significant pressure on the ends of the telescopic device.
- the seal is mounted on the inner tube and the ring is mounted in the outer tube.
- the ring comprises a crown coming substantially into contact with the external wall of the inner tube and the seal is disposed between the end of the inner tube and the crown.
- the tubes are made of plastic, and even more advantageously of injected or extruded plastic.
- This arrangement is particularly suitable for the telescopic device according to the present invention.
- the stress on the seal is minimized by virtue of the presence of the annular space in part of the intermediate positions between the retracted position and the extended position, and preferably in the majority of the intermediate positions.
- the construction is well suited to the dimensional tolerances, the stiffness and friction characteristics of these materials. This arrangement makes it possible to obtain a particularly light, economical and simple to use telescopic device.
- the objects assigned to the invention are also achieved using a vacuum cleaner which includes a telescopic device according to the invention.
- FIG. 1 shows in a longitudinal section view a device in the retracted position
- FIG. 2 shows in a longitudinal section view a device in the extended position
- FIG. 3 shows in a longitudinal section view a detail of a device in the extended position
- FIG. 4 shows in a longitudinal section view a detail of a device in an intermediate position
- FIG. 5 schematically shows a telescopic device in the retracted position mounted on a vacuum cleaner
- FIG. 6 shows schematically a telescopic device in the extended position mounted on a vacuum cleaner.
- the telescopic device shown in Figures 1 and 2 comprises an inner tube 1 and an outer tube 2, the inner tube 1 being capable of sliding in the outer tube 2 between a retracted position, shown in Figure 1, and an extended position, shown in FIG. 2.
- the device also comprises an annular seal 3, intended to ensure a seal between the inner tube 1 and the outer tube 2, as well as a latch 5 mounted on the outer tube, intended to block the two tubes 1, 2 in at least one position.
- the latch 5 comprises a pusher 16 pivotally mounted on the outer tube 2 against a spring 17, said pusher having one end 18 capable of engaging in a notch 19 formed on the inner tube 1 to lock the tube outside 2 on the inside tube 1.
- the seal 3 cooperates with a ring 6 to seal the device when the outer tube 2 is locked in the extended position on the inner tube 1 by means of the latch 5, and provides an annular space 7 with a wall 21 of one of the tubes 1, 2 when the inner tube 1 occupies at least one intermediate position, and preferably the majority of the intermediate positions, between the retracted position and the extended position.
- the seal 3 is mounted on the inner tube 1 and the ring 6 is mounted in the outer tube 2.
- the wall 21 is then formed by an inner wall of the outer tube 2, as as shown in Figure 4.
- the seal 3 is mounted on the inner tube 1 and the ring 6 is mounted in the outer tube 2.
- the wall 21 is then formed by an outer wall of the inner tube 1.
- the inner tube 1 has an outer wall 8 of cylindrical shape comprising a first guide means 9 cooperating with a second guide means 10 mounted in the outer tube 2.
- the first guide means 9 has at least one groove or a flat cooperating with at least one lug forming the second guide means 10.
- the second guide means 10 is formed by two lugs 20.
- the outer tube 2 has an inner wall 11 which is conical. This arrangement is advantageous in particular when the tube 2 is made of injected plastic. As shown in the figures, the end of the outer tube 2 opposite the latch 5 has an inner diameter smaller than that of the other end.
- the inner tube 1 has one end 22 having an outer conical chamfer 12 capable of cooperating with an inner conical chamfer 14 formed in the outer tube 2, when the inner tube 1 is in the retracted position in the tube exterior 2, as shown in Figure 1.
- the chamfers 12, 14 are provided to ensure a non-blocking abutment, the angles of said chamfers being for example sufficiently large to avoid an almost irreversible tightening of the outer tube 2 on the inner tube 1 during a rapid approach of the two tubes.
- the taper of the outer tube 2 can be chosen so that the seal 3 can come into contact only with the ring 6 with the exception of the wall inner 11 of the outer tube 2 or the outer wall 8 of the inner tube 1.
- the ring 6 has a crown . 7.
- the crown 15 comes substantially into contact with the outer wall 8 of the inner tube 1, so as to scrape the wall 8, as shown in FIG. 3.
- the gasket 3 is disposed between the end 22 of the inner tube 1 sliding in the outer tube 2, and the crown 15.
- the crown comes substantially into contact with the inner wall 11 of the outer tube 2, so as to scrape the wall 11, as shown in FIG. 4.
- the crown is disposed between the end 22 of the inner tube 1 sliding in the outer tube 2, and the seal 3.
- the tubes 1, 2 are made of plastic, and even more advantageously of injected or extruded plastic.
