Abstract
Abstract A worm and worm wheel reduction mechanism for use in vehicle window operating mechanism wherein said mechanism includes a housing rotatable with the worm wheel, a shaft for connection to window moving means, a guide member rotatable with said shaft, an anchoring member rotatable with said guide member and radially slidable therein between a coupled position in which it enters a recess formed in said housing for rotatably connecting said housing and said worm wheel to said shaft and an uncoupled position in which it is disengaged from said recess to disconnect said housing and worm wheel from said shaft, there being also provided a resilient member which acts on said anchoring member so as to urge it towards its coupled position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
For use in means for operating the side-windows in automobile vehicleS, said means comprising an electric motor and a pinion which in use engages a toothed part connected to a lever for moving the window, a worm and worm wheel reduction mechanism for transmitting the torque of said electric motor to said pinion wherein said mechanism includes a guide member which is rotatable with a shaft of the reduction mechanism, means for coupling said worm wheel to said guide member constituted by an anchoring member which engages when in a coupled position in a correspondingly shaped recess formed in a housing connected to the worm wheel, means for sliding said anchoring member radially on said guide member rotatable with said shaft for disengaging the anchoring member from the housing and a resilient member which exerts a force tending to maintain the anchoring member in its coupled position.
Claim 2
Dependent Claim
147 words
For use in means for operating the side-windows in automobile vehicleS, said means comprising an electric motor and a pinion which in use engages a toothed part connected to a lever for moving the window, a worm and worm wheel reduction mechanism for transmitting the torque of said electric motor to said pinion wherein said mechanism includes a guide member which is rotatable with a shaft of the reduction mechanism, means for coupling said worm wheel to said guide member constituted by an anchoring member which engages when in a coupled position in a correspondingly shaped recess formed in a housing connected to the worm wheel, means for sliding said anchoring member radially on said guide member rotatable with said shaft for disengaging the anchoring member from the housing and a resilient member which exerts a force tending to maintain the anchoring member in its coupled position.
Claim 3
Dependent Claim
105 words
A worm and worm wheel reduction mechanism as claimed in claim 1, wherein said means for sliding said anchoring member comprise an operating member, freely mounted on said shaft of the reduction mechanism and having an attachment in which is formed a V-shaped hole which receives a lug forming part of said anchoring member, the shape of said hole being such that when the operating member is rotated in one direction or the other, it communicates to said anchoring member a radial movement relative to said guide member so as to ensure that said anchoring member is coupled or uncoupled in relation to the housing.
Claim 4
Dependent Claim
76 words
A worm and worm wheel reduction mechanism as claimed in claim 2 wherein the resilient member is constituted by a part which is shaped like a hair-pin, the middle part of which is loop-shaped and is attached to a curved tab of the guide member, while its prongs abut on the lateral sides of the operating member in such a way that they tend always to bring the anchoring member back to its initial coupled position.
Claim 5
Dependent Claim
78 words
A worm and worm wheel reduction mechanism as claimed in claim 2, wherein said means for sliding said anchoring member also includes a push button which is resiliently urged towards a rest position and which can be pressed into engagement with the operating member so as by friction to cause said member to become locked and to bring about an uncoupling of the anchoring member from the housing as long as pressure is exerted on the push button.
Claim 6
Dependent Claim
106 words
A worm and worm wheel reduction mechanism as claimed in claim 2, wherein the resilient member is constituted by a leaf spring, one of the end of which is secured to a curved tab of the guide member, the other end, which is free, being shaped in such a way that it exerts pressure on the anchoring member to oppose inward radial movement thereof relative to the shaft of the reduction mechanism, said leaf spring being shaped to fit into a recess formed in the operating member so as to hold said operating member in a position corresponding to the coupled position of the anchoring member.
Claim 7
Dependent Claim
103 words
A worm and worm wheel reduction mechanism as claimed in claim 2, wherein the resilient member is formed by moulding plastics material and has a hole in which a curved tab of the guide member engages and a wall which can be deformed resiliently so as to exert a pressure on the anchoring member against inward radial displacement thereof relative to the shaft of the reduction mechanism, the middle part of said wall having a projection which fits into a recess formed in the operating member to hold said operating member in a position corresponding to the coupled position of the anchoring member.
