Definitions

  • the subject of the invention is a mechanism which is used to adjust, at a distance from a wheel, the tool of an apparatus used for fitting and removing an automobile tire, said wheel being fixed on a table controlled by a motor and animated by a rotational movement along said tool.
  • Apparatuses which, in main order, consist of a frame, a claw table between which the wheel is fixed, a control member making it possible to move the claws and to cause the table to rotate, a vertical column mounted on the aforementioned frame, a horizontal arm placed transversely in the aforementioned column and capable of sliding and being fixed therein, of a bar with a tool used to install and remove the tire, this bar being able to be adjusted and fixed in height at the end of said horizontal arm, and by a relatively complicated means for adjusting, both in a horizontal and vertical plane, the tool at a determined distance from the fixed wheel, beyond so as to avoid friction between the wheel and the tool.
  • the object of the invention is to provide a relatively simple construction mechanism by means of which only a minimum of manipulation is necessary to place the tool at the desired distance from the wheel.
  • the arm transversely displaceable in the vertical column is oblique and inclined towards the wheel and between the arm and the vertical column there is provided a means making it possible to move and block the above-mentioned arm.
  • FIG. 1 we see the frame 1, in which is housed a control mechanism of a well-known device 2 with claws 3 for fixing and controlling the wheel 4 so as to rotate it.
  • the device can be provided with a well-known device 5 for taking off the tire.
  • a hollow column 6 is fixed to the frame 1.
  • This column 6 carries a box 7 at the upper part. In this box, it is mounted obliquely and inclined towards the wheel, an axially displaceable arm 8, guided between two rollers of guide 9 mounted diagonally and two tenons 10 mounted diagonally. Thanks to this arrangement, the arm 8 can be rolled in the boot 7 and is mounted at a fixed angle.
  • the end of the arm 8 directed towards the wheel 4 is provided with a block 11 in which is vertically suspended a bar 12 with handle 13.
  • This bar is adjustable in height and can, thanks to a locking means 14 with handle 15, be fixed in the block 11. Between the handle 13 and the block 11, a pressure spring 16 is placed, which balances the weight of the bar 12.
  • the tool which is used to install and remove the tire from the wheel is fixed to the lower part of this bar 12.
  • the pressure roller 17 which is fixed on the support 18 of the bar 12, which pressure roller cooperates with the bead of the tire to be laid.
  • the guide roller 19 which is used to guide the bead of the tire outside the circumference of the rim of the wheel during the fitting of the tire.
  • a freewheel 20 which can rotate freely in the direction of rotation of the needles of a watch but not in the opposite direction.
  • This wheel free is mounted between two flanges 21-22 in the form of a disc. Via a shaft 23, it is mounted on the boot 7 the end of a toothed segment 24 which, by means of a handle 25 placed at the other end of said segment, can be engaged with the freewheel 20.
  • the flanges 21-22 also cover the part engaged with the freewheel 20 of the toothed segment 24.
  • the axis 23 of the toothed segment 24 consists of a bolt with nut. and between the toothed segment and the nut there is provided a spring washer which exerts pressure on the toothed segment, so that the toothed segment can be placed and maintained in a desired position.
  • a counterweight 26 is placed in the column 6 which, by means of a cable 27 passing over a target roller 28, is fixed to a small block 29 of the arm 8
  • the cable 28 is housed in a groove 30, provided in the lower part of the arm 8.
  • the toothed segment 24 is preferably provided with two stops which cooperate with fixed parts of the boot 7 to limit the two extreme positions of this segment
  • the arm 8 is rolled backwards in the boot 7, this in such a way that the tool which is used to install or remove the tire, is at a distance from the device 2 for fixing the wheel ( fig. 2).
  • the toothed segment 24 is pivoted on its axis 23 in the extreme forward position (fig. 2).
  • a wheel 4 is placed between the claws 3. of the above-mentioned device 2 and the wheel is fixed to this device which can be of any type. We. then put a tire obliquely on the wheel in the well known manner.
  • the arm 8 is rolled towards the wheel 4 and the bar 12 is released by the handle 15 to lower the tool; this until that the extreme upper edge of the wheel is in contact with the tool in the angle formed between the pressure roller 17 and its support 18. Then the bar 12 is fixed by the handle 15 in this position.
  • the slightest displacement of the latter in the direction opposite to the wheel automatically gives a clearance of the tool 17-19 both in the vertical plane and in the horizontal plane, relative to the wheel 4.
  • the freewheel 20 cannot rotate in the opposite direction to that of the rotation of the hands of a watch, it is impossible to move, in this position, the arm 8 towards the wheel 4, while it it is however possible that the arm 8 with the tool 17-19 can move away from the wheel 4 when for example the wheel is not completely round and that therefore the wheel exerts pressure on the tool.
  • the tool 17-19 can be removed entirely from the wheel 4 by rolling the arm 8 backwards then bringing it back towards the wheel without having to start the adjustment again.
  • the control device 2 which firmly holds the wheel is switched on, so that the driven wheel is driven by a rotational movement and the tire is placed entirely on the wheel, without the fitting tool or the tire removal tool comes into contact with the wheel.
