Abstract

(57) [Abstract] [Purpose] The purpose is to prevent the cross section of the sash frame from increasing by using a slide window glass fixing device that does not apply concentrated load to the sash frame. [Structure] Sliding in two grooves parallel to each other 2
A device for fixing a sliding window glass, in which a pair of window glasses is sandwiched by a pair of brackets, and the pair of brackets are tightened by bolts penetrating holes formed above the upper groove or below the lower groove.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing device for two window glasses that slide in a groove provided with two upper and lower windows, and more particularly, to a fixing device for a sliding window glass on the side of the cab of a construction machine such as a bulldozer. .

[0002]

[Prior Art]

 As shown in FIG. 7 which is a sectional view of FIG. 6 and FIG. 7 which is a Z view of FIG. 5, a conventional fixing device for a sliding window glass has a protruding portion 25a of a window frame 25 sandwiched by a sash frame 22 from both sides. Glass 21 is attached to the sash frame 22 by a sealing material 26, a bracket 23 is attached to the sash frame 22 with a screw 24, and a pair of pins are attached to the bracket 23. A portion 23a is provided, a pin hole 23b is bored in the pin attachment portion 23a, a lever 27 is attached by a pin 28 between the pin attachment portions 23a, and the position of the lever 27 is indicated by a chain double-dashed line. That is, at the FREE position, the sash frame 22 is free to move, and at the LOCK position shown by the solid line, the protruding portion 27a of the lever 27 is attached to the window frame 25. Per can Satu Shiyu frame 22 is fixed.

[0003]

[Problems to be solved by the device]

 In such a conventional slide glass fixing device, when the lever 27 is set to the LOCK position, the reaction force of the lever 27 pressing the window frame 25 acts on the sash frame 22 as a concentrated load. However, in order to increase the strength, the sash frame 22 having a large cross section is required, and if the cross section is increased, the visibility is deteriorated, and the weight and cost are increased. In order to solve the conventional problems, the present invention aims to provide a slide glass fixing device that can be used even in a sash frame having a small cross section.

[0004]

Means for Solving the Problems Two windows that are parallel to each other are provided at the top and bottom, and two windows that slide in the two windows are fixed in a device for fixing the two windows. The above problem is solved as a fixing device for a sliding window glass, characterized in that it is sandwiched by brackets and the pair of brackets is tightened by bolts that penetrate through holes formed above the upper groove or below the lower groove. did.

[0005]

[Action]

 It is not necessary to use a sash frame with a large cross section by tightening the bolts with an appropriate tightening force.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a cab 1 of a bulldozer. The cab 1 is provided with a door 2 for opening and closing and a side window 3, and the side window 3 is provided with a frame 7 above and a frame 8 below. The frame 7 and the frame 8 are each provided with two parallel grooves, and slide window glasses 9a and 9b are slidably fitted in the respective grooves. The fixed glass 4 is fitted over the frame 7. A slide window glass fixing device 10 will be described in detail with reference to FIGS. 2 to 3.

2 is a sectional view taken along the line AA of FIG. 1, FIG. 3 is a sectional view taken along the line BB of FIG. 1, FIG. 4 is a sectional view taken along the line CC of FIG. 1, and FIG. It is a figure which shows the state which the fixing device 10 of FIG. In the figure, the upper frame 7 is provided with an inner groove 7a and an outer groove 7b, and the lower frame 8 is provided with an inner groove 8a and an outer groove 8b, and the respective grooves 7a and 7b are provided. , 8a, 8b are attached with seals. A sliding window glass 9a is slidably fitted in the inner grooves 7a and 8a, and a sliding window glass 9b is slidably fitted in the outer grooves 7b, 8b. A seal material 11 is attached from the center of the frame 7 in the longitudinal direction to the center of the frame 8 in the longitudinal direction. The seal material 11 is sandwiched between a slide glass 9a and a slide glass 9b to form a slide glass 9a. The space between the slide glasses 9b is sealed.

The sliding window glass fixing device 10 includes an inner bracket 12a and an outer bracket 12b in a state where the sliding window glass is sandwiched, bolts 13 attached to the outer bracket 12b and penetrating through holes 4a of the fixing glass 4, and a fixing glass 4. The seals 14a and 14b to be held, the cushion rubber 16a fitted in the hole 15a of the inner bracket 12a, the cushion rubber 16b fitted in the hole 15b of the outer bracket 12b, and the inner bracket 12a provided with the frame 7 to prevent rotation. The groove 17a and the outer bracket 12b are provided with a rotation preventing groove 17b for engaging with the frame 7, and a lock knob 18 having a screw hole for screwing with the bolt 13.

With the above-described structure, the lock knob 18 is rotated in a loosening direction, the slide window glass 9a and the slide window glass 9b are released by an appropriate amount, and the lock knobs 18 are tightened. The cushion rubbers 16a and 16b fitted in the clamps sandwich and fix the sliding window glasses 9a and 9b.

[0010]

[Effect of the device]

 As described above, the present invention does not require a frame having a particularly high rigidity if the lock knob 18 is tightened with an appropriate strength.
