Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a window regulator device for opening and closing a window glass of a vehicle such as an automobile.

[Prior art] In a conventional window regulator device, a window glass rotates a main arm interlocked with a handle by operating a handle, and a roller provided on the main arm is fitted into a main guide to form the main arm. There is widely used a device in which a main guide is moved up and down by a roller and a roller of a sub arm, and a window glass attached to the main guide via a holder is moved up and down to open and close a window.

[Problems to be Solved by the Invention] In a conventional window regulator device, a main guide and a glass holder / coupling portion are aligned in an assembly factory and a bolt is tightened, or a bolt is taken out from the glass holder side and then a nut is provided. However, there is a disadvantage in that it takes time and labor to tighten and the productivity is reduced.

Further, since nothing is applied to both ends of the main guide, there is a problem that the rollers and the like fall off from the main guide when the window regulator is transported to the assembly factory.

[Means for Solving the Problems] In view of such circumstances, the present invention provides a slide portion continuous with the bolt holes at both ends of the main guide in order to cope with both problems, and furthermore, at one end of the main guide. A notch is provided in the bolt hole, and a holder connected to the sub-arm via a shaft is fitted. The holder is provided with a drop-off prevention claw that locks in the dropping direction, to improve glass assemblability and assembly. For the purpose of preventing the rollers and the like from dropping during the transportation.

[Operation] A drop-off preventing claw 2a is provided at a part of a notch provided at one end of the main guide 1 provided with a slide portion 1b continuous with the bolt hole 1a at both ends, and the tip of the sub arm 4 is connected via the shaft 6. When the connected holder 2 is slide-fitted and the glass holder 17 is assembled to the main guide 1, a bolt from the glass holder is inserted into a bolt hole of the main guide, the main guide 1 is slid, and a bolt is tightened at the slide portion. Install the holder. Further, when the product is transported, when the holder 2 slidingly fitted to the main guide 1 acts in the detaching direction, the falling-off preventing claw 2a provided on the holder 2 is hooked on the notch 1c provided on the main guide 1 to prevent falling off. I do. Further, when assembling to the glass holder 17 and the main guide 1, the holder 2 between the glass holder 17 and the main guide 1 is fastened together, and the main guide 1 and the sub arm 4 are fixed to prevent swinging when the glass is moved up and down.

[Embodiment] Next, an embodiment of the window regulator device according to the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a main guide having a C-shaped channel cross section. Bolt holes 1a are provided at both ends of the main guide 1 and a slide portion 1b which is continuous with the main body 1 in the longitudinal direction. Are cut out in a zigzag shape, and the bolt hole 1a, the slide portion 1b and the notch portion 1c continuous with the bolt hole 1a in the longitudinal direction are provided in this portion.

At one end of the main guide 1, the notch
A holder 2 provided on one end side with a drop-off preventing claw 2a which is hooked in the pull-out direction on 1c, and a spherical bearing portion 2b is integrally provided on the other end of the holder 2, and a main arm 3 described later is provided. And a sphere 6a of a shaft 6 on which the tip of one of the sub-arms 4 of the arm A constituted by an X-shaped link mechanism consisting of two sub-arms 4 and 5 is fitted. It is swaged so as not to fall out. The holder 2 is formed in a C-shaped cross section so as to slide into an end notch of the main guide 1, and extends in a longitudinal direction from an end having substantially the same diameter as a bolt hole 1 a provided in the main guide 1. Slot 2c and this slot 2c
The falling-off prevention claw 2a is provided at the one end of the base member so as to have elasticity and protrude inward.

Main arm 3 and sub-arms 4, 5 divided into two
Fits the convex shafts formed by punching the base ends of the sub-arms 4 and 5 from both sides into the shaft holes provided at the substantially central part of the main arm 3, and the shafts at the base ends can be rotated. And is fixed to the arm of the X-shaped link by welding or the like. The other end of the sub arm is slidably supported by a sliding member 8 slidably fitted on a fixed guide 7 having a C-shaped cross section fixed to the door of the automobile via a shaft 9. Further, the distal end of the main arm 3 is supported by a sliding body 10 slidably fitted to the main guide 1 via a shaft 11, and the base end has a shaft 3a.
The shaft 3a is rotatably supported by being fitted in a shaft hole provided at an end of a substrate body 12 fixed to a door of an automobile. Further, the shaft 3a has a spiral balance spring. One end of the balance spring 13 is engaged, and the other end of the balance spring 13 is engaged with the substrate main body 12 so as to be balanced.

At the base end of the main arm 3, a sector gear 15 meshing with a driving pinion 14 provided on the other end side of the substrate main body 12 has an arm piece.
The main arm 3 is rotated about the shaft 3a when the pinion 14 is rotated by an operation handle (not shown).

Reference numeral 17 denotes a glass holder, which is provided with a bolt 17a and fastened.

[Effects] As is clear from the above description, the present invention provides
A bolt hole is provided at both ends of the main guide, a slide portion is provided in the coarse bolt hole for connection in the longitudinal direction, and a notch is provided at one end of the main guide and a sub arm is provided at one end of the main arm. By mounting a holder having a drop-off prevention claw connected via a shaft and a shaft, it is simply assembled without the need for alignment when assembling the glass, improving productivity, and further fixing the main guide and sub-arm. This prevents rocking when the glass is raised and lowered.

Further, it is possible to prevent the rollers and the like from dropping off from the main guide during the transportation for improving the assembling, and it is possible to prevent the regulator from being damaged or the like.
