Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a sliding window opening/closing device, and in particular to a sliding window opening/closing device that is composed of two window glasses and is opened/closed by sliding the window glasses mutually in a sliding manner. Related to a type window opening/closing device.KPrior art] For example, a truck cab door is provided with a sliding type window, and two window glasses are attached to the door. The windshield is configured to be opened and closed by moving. Conventionally, such sliding type windshields were operated manually. Therefore, they could not be opened and closed for automatic fishing. In order to solve this inconvenience, for example,
As disclosed in Japanese Patent No. 51971, it is considered to move the above-mentioned window glass using a driving means such as a motor, but it is possible to move the two window glasses independently of each other. Therefore, if these window glasses were to be slid by a common motor, it would not be possible to open or close only one of the window glasses independently. In other words, a drawback arises in that it is no longer possible to selectively open and close the two window glasses. In addition, as in Japanese Utility Model Application Publication No. 57-29785, when the racks attached to the lower ends of two window glasses are selectively driven by a common drive, the two window glasses are moved in opposite directions. cannot be moved at the same time.

[Purpose of the invention]

The present invention has been made in view of these problems, and does not involve sliding the two windshields together using a driving means such as a single motor.
It is an object of the present invention to provide a sliding window opening/closing device that can selectively slide either one of the window glasses. K Structure of the Invention] The present invention provides a sliding type window which is composed of two window glasses and is opened and closed by sliding the window glasses mutually in a sliding manner. A rack extending in the sliding direction is installed at a position almost opposite to the rack, and a pinion that engages with these racks and is movable in the axial direction is arranged between these racks, and the axial direction of this pinion is The configuration is characterized in that the shapes of the pair of racks are changed or their positions are shifted so that, by movement, the state in which the nion is engaged with the pair of racks and the state in which it is engaged with one of the racks is changed. This relates to a sliding window opening/closing device, which allows two window glasses to slide together in a sliding manner, and also allows one of the window glasses to slide independently if necessary. It is something.

【Example】

The present invention will be explained below with reference to an illustrated embodiment. FIG. 1 shows a truck door 1 equipped with a sliding window opening/closing device according to an embodiment of the present invention, and a door window 2 is provided at the top of the door 1. As shown in FIG. Door window 2 has a pair of front and rear window glasses 3.4
It consists of Of these window glasses 3.4, the front window glass 3 is attached to the outside, and the rear window glass 4 is attached to the inside, so that they slide against each other in a sliding manner. Next, the structure for sliding the window glass 3.4 will be explained with reference to FIG. 2. The door 1 is composed of an outer panel 5 and an inner panel 6, and there is a An aluminum sash 8 is attached via an adhesive layer 7. The sash 8 is provided with rails on the outside and inside, respectively, and these rails 9 are engaged with sliders 11 of the glass frame 10. Note that the inner portion of the groove of the slider 11 that is engaged with the rail 9 is provided with flocks 12. The window glasses 3.4 are attached to these glass frames 10 through fillers 13, respectively. Next, I will explain the mechanism by which these windows automatically slide the laths 3.4. Inside the glass frame 10 that supports the outer window glass 3, there are a pair of vertically separated widths. A narrow rack 14 is fixed. On the other hand, a wide rack 15 is attached to the outside of the glass frame 10 that supports the inner window glass 4. This rack 15 has a width approximately twice that of the rack 14, and its upper end coincides with the upper end of the upper rack 14 on the window glass 3 side. A pinion 16 is arranged between the racks 14.15 so as to mesh with these racks 14.15. The pinion 16 is fixed to the upper end of a shaft 17, and a long gear 18 is fixed to the shaft 17 as shown in FIG. long gear 18
is adapted to mesh with a drive gear 19, and the drive gear 19 is adapted to be driven by a motor 2o. Next, the mechanism for vertically moving the pinion 16 for automatically sliding the windshield 3.4 will be explained. At the lower end of the shaft 17, as shown in FIG. A sleeve 21 is secured, the groove of which is adapted to receive a fork 22. And the fork 22 is the bin 23
The fork 22 is rotatably supported by the fork 22, and a wire cable 24 is connected to the tip of the fork 22. An operation button 25 is fixed to the tip of the wire cable 24. Next, the operation of the opening/closing device for the sliding window 2 constructed as described above will be explained. First, by operating the operation button 25 provided on the driver's seat, the driver selects whether to move both of the pair of window glasses 3.4 or only one of them. The operation button 25 is connected to the fork 22 via the wire cable 24 like a book, so the operation button 25 can be used to control the fork 22.
can be rotated about the pin 23, thereby allowing the shaft 17 to be moved in its axial direction via the shifting sleeve 21. Therefore, by moving this shaft 17, it is possible to move the shaft 16 in its axial direction, and it is moved between the position shown by the solid line, the dotted line, and the chain line in FIG. You will be able to do this. When the window 16 is in the position shown by the solid line, the rack 14.1 of the glass frame 10 of the window glasses 3.4 on both sides
5 are both engaged with the pinion 16, so that both window glasses 3.4 can be slid together and slid in opposite directions. On the other hand, when the pinion 16 is moved to the position shown by the dotted line in FIG. Only the last 4 can be slid. Furthermore, by moving the pinion 16 to the position indicated by the chain line, this pinion 16 meshes with the rack 14 of the glass frame 10 of the outer window glass 3.
This makes it possible to slide only the outer window glass 3. Once the window glass 3.4 to be slid is selected using the operation button 25 in this manner, the motor 20 is rotated by operating the operation button (not shown). Then, the motor 20 rotates in a predetermined direction, and this rotation causes the drive gear l1-1 to rotate.
9 and the long gear 18 to the pinion 16. This rotation of the pinion 16 causes both or one of the window glasses 3.4 to slide via the rack 14.15 and the corresponding glass frame 10. The window glass 3.4 is therefore automatically opened and closed in this way. Note that since the control circuit of the motor 20 is connected to an opening regulation switch (not shown), the motor 20 is automatically stopped in the fully open state or in the fully open state to prevent damage to the drive system. Next, a modification of the above embodiment will be explained with reference to FIG. In this modification, parts corresponding to those in the above embodiment are given the same reference numerals, and descriptions of parts having the same structure will be omitted. In this modification, the rack 14 on the side of the window glass 3 and the rack 15 on the side of the window glass 4 are both configured to have the same width, and are mounted to the corresponding glass frame 10 while being shifted from each other in the height direction. This is what I did. Therefore, if the pinion 16 is located at the position indicated by the solid line in FIG. 4, both racks 14,15 and this pinion 16 mesh. On the other hand, when the pinion 16 rises and moves to the position indicated by the dotted line, the pinion 16 meshes only with the rack 15 on the window glass 4 side. On the other hand, when the pinion 16 descends and moves to the position shown by the chain line, the pinion 16 moves toward the windshield 3.
It will mesh with the rack 14 on the side. Therefore, even with this modification, by moving the pinion 16 attached to the tip of the shaft 17 in the axial direction, not only can the pair of window glasses 3.4 be opened and closed simultaneously, but also the pair of window glasses 3.4 can be opened and closed simultaneously. It becomes possible to selectively slide one of the window glasses 3.4, and it becomes possible to achieve the same effects as in the above embodiment. Moreover, in this modified example, the racks 14 and 15 have the same shape, and since it is only necessary to mount them by shifting their positions, it is possible to standardize these parts. Although the present invention has been described above with reference to the illustrated embodiment and its modified examples, the present invention is not limited to the above embodiment and its modified examples, and various modifications can be made based on the technical idea of the present invention. be. For example, the above embodiment relates to a door window opening/closing device for a truck, but the present invention can be applied not only to a door window but also to various other sliding window opening/closing devices, such as a sliding window for a bus. Also available for windows. [Effects of the Invention 1] As described above, the present invention has racks extending in the sliding direction installed at positions substantially opposite to each other on a pair of window glasses, and a structure in which the racks are interlocked with the racks between the racks. In addition, a pinion that is movable in the axial direction is arranged, and the pair of racks is arranged so that the pinion changes into four states in which it meshes with the pair of racks and a state in which it meshes with one rack by the movement of the pinion in the axial direction. The shapes of the objects are changed or their positions are shifted. Therefore, by simply moving the pinion in the axial direction,
Not only can a pair of window glasses be simultaneously slid in opposite directions, it is also possible to selectively move one of the window glasses.
