Problems solved by technology

[0004] However, in the vehicle window opening and closing device described in JP-A-5-202673, a large number of parts such as guide rails, sliders, and two cables are required, and the structure is complicated and the cost is high.
In addition, because the guide rails are arranged on the lateral side of the closed window glass, the degree of freedom of arrangement is small, and when one of the cables breaks, the window glass will collapse due to its own weight. open questions like
[0005] In addition, in the vehicle window opening and closing device described in the Publication of Unexamined Publication No. 63-104583, a large number of components such as two rocker arms, a fixed plate, and a gear plate are required, and the structure is complicated and the cost is high.
In addition, since two swing arms are arranged on the lower side of the window glass that has been slid to the closing direction, there is a problem that the degree of freedom of arrangement is small.

Embodiment approach 1

[0066] figure 1 It is a schematic front view showing the composition of the opening and closing device in the present invention, figure 2 It is an enlarged front view of important parts of the switchgear, image 3 It is an enlarged plan view of important parts of the switchgear

[0067] In the opening and closing device shown in the drawing, a slider A slidably attached to a vehicle window (opening) slides in a closing direction and an opening direction. The opening and closing device includes: two rotating gears 1, 2 separated in the radial direction and parallel to the axis; Two chains 3, 4; a support body 5 freely rotatably supporting each rotating gear 1, 2; a motor 6 for synchronously rotating each rotating gear 1, 2; isolating each chain 3, 4 to the rotating gear 1, 2 The guide body 7 for guiding in the direction; the two storage parts 8, 8 at the ends of the chains 3, 4 guided by the guide body 7 for storage.

[0068] Rotary gear 1 contains such as figure 2 as we...

Embodiment approach 2

[0087] Figure 9 It is a schematic front view showing another configuration of the switch device. The opening and closing device of this embodiment is configured as follows: the rotating gears 1 and 2 arranged at a distance in the lateral direction are slightly offset up and down, and the one end sides of the chains 3 and 4 arranged oppositely between the rotating gears 1 and 2 face each other. Move in a vertical and inclined direction.

[0088] In this embodiment, for example, the window glass (sliding body A) mounted on the vehicle window slidably in a direction inclined relative to the vertical can be moved in the opening direction / closing direction as in the first embodiment. to swipe.

[0089] Since other configurations and functions are the same as those in Embodiment 1, the same symbols are assigned to the same components, and detailed descriptions and descriptions of the functions are omitted.

Embodiment approach 3

[0091] Figure 10 It is a schematic explanatory diagram showing another configuration of the switching device. In the opening and closing device of this embodiment, the rotation gears 1, 2 are prevented from being deflected by deflection preventing portions 35, 35..., 45, 45... toward one end side on each chain 3, 4. The longitudinal direction of the non-bending part of the sliding body A, in other words, the direction in which the sliding body A slides is isolated and arranged. In addition, there is also a configuration in which one of the two substantially L-shaped guide bodies 7a, 7c (guide body 7a) is arranged near the rotating gear 1, and the other guide body 7c is arranged near the rotating gear 2, so that Each of the chains 3 and 4 is guided in the same direction intersecting with the longitudinal direction of the non-bending portion. In addition, the storage parts 8, 8 are spaced apart and arranged in the longitudinal direction of the above-mentioned non-bending part...

Abstract

An opening / closing unit includes rotary gears spaced apart from each other in a radial direction, and chains which are placed to face each other, engage individually with the respective rotary gears and move in an interlocking manner, have flexible chain sections and flexure preventing sections which project from the chain sections and come into engagement with each other at a point located on one end side with respect to an engaged portion where the chains engage with the rotary gears, and are attached at their one ends to a sliding body such as a window glass, the flexure preventing sections are brought into engagement with each other to prevent the chains from flexing in separating directions and join them together to make one end side of the chains a non-flexible portion in the form of an angular bar.

Description

technical field [0001] The present invention generally relates to an opening and closing device for opening and closing the above-mentioned opening through a sliding body slidably installed on the opening, and opening and closing the above-mentioned vehicle window through a window glass slidably installed on the vehicle window. Window opening and closing device. Background technique [0002] Automobile doors are assembled with: a window glass and an opening and closing device for sliding the window glass so as to open and close the window (for example, refer to Japanese Patent Laying-Open No. Hei 5-202673 and Japanese Utility Model Publication Zhao 63-104583 Bulletin). The opening and closing device described in Japanese Patent Laid-Open No. 5-202673 includes: a guide rail arranged up and down and having cable guides at the upper and lower ends; body; two cables fixed to the above-mentioned cable guide, one end of which is combined with the above-mentioned sliding body; an...
