Description

[Detailed Description of the Invention] The present invention relates to a sliding window that eliminates the level difference between the inner glass and the outer glass when closed.

Conventionally, when sliding windows on the sides of vehicles such as vans and buses are closed, a step equivalent to the thickness of the outer glass is created between the surfaces of the outer glass and the inner glass, resulting in an unsightly appearance. Not only was it bad, but it also had drawbacks such as wind noise and air resistance while driving.

In order to eliminate the drawbacks of the conventional method, this invention aims to eliminate the level difference between the inner glass and the outer glass by forming the inner glass so that it protrudes on the same plane as the outer glass when the inner glass is closed. It is.

An example of the implementation of the present invention will be explained with reference to the drawings. 1 and 2 are horizontal and parallel cross sections installed inside the window frame provided on the side of the vehicle body.
The upper and lower sashes are long in the shape of a letter, and both are open on the outside, that is, on the side where the window glass is installed, and constitute the sashes 1 and 2, respectively. There is an upper guideway 1 in the center of the hanging walls 1a and 2a.
b and 2b, and further the upper end of the hanging wall 1a and the hanging wall 2a.
A cover plate 1c and a lower guide path 2c are provided at the lower end, and a lower frame 1d and an upper frame 2d each having a rectangular cross section are provided at the lower end of the hanging wall 1a and the upper end of the hanging wall 2a. The lower frame 1d of the hanging wall 1a is provided in parallel along the longitudinal direction of the hanging walls 1a and 2a, with a width and a vertical interval that allow the roller 4 of the inner glass 3 to roll.
The upper plate is used as the lower guide path 1e of the sash 1. Guide grooves 9 for guiding the cams 8 provided on the inner glass 3 via the cam brackets 7 are bored in the longitudinal direction in the lower plate 1f of the lower frame 1d and the upper plate 2e of the upper frame 2d, respectively. Furthermore, the meandering grooves 9a, 9a, which communicate with the guide groove 9, are connected to the middle and end of each guide groove 9, that is, the positions where the upper and lower front and rear cams 8 reach when the inner glass 3 is closed. glass 3
The upper and lower front and rear cams 8 are bored in a direction approaching the outer glass 5 side. 10 is the inner surface 3a of the inner glass 3
The leaf springs 10 have elasticity to press the inner glass 3 toward the outer glass 5, and one end 10a of the leaf spring 10 is adhesively fixed to the inner surface 3a of the inner glass 3, and each At the other end 10b of the leaf spring 10,
Rollers 4, 4 for opening and closing the inner glass 3 in the front and rear directions by rolling on the lower guide path 1e of the sash 1 and the upper guide path 2b of the sash 2 are spaced apart by two rollers through the mounting plate 11. Arrange horizontally and support the shaft. Further, L-shaped cam brackets 7 are fixed horizontally to the four corners of the inner surface 3a of the inner glass 3, and each cam bracket 7 is provided with a cam 8 facing upward or downward. Handle 12 at the end
to protrude. At the four corners of the inner surface 5a of the outer glass 5 are U.
The outer wall portions 13a of the letter-shaped bracket 13 are fixed to each other, and the horizontal wall portion 13b continuous inward from the outer wall portion 13a is straddled so as not to contact or interfere with the upper and lower edges 3b, 3c of the inner glass 3. On the outside of the inner wall part 13c, which stands upright next to the horizontal wall part 13b, the outer glass 5 is moved forward and backward by rolling along the upper guide path 1b of the sash 1 and the lower guide path 2b of the sash 2. The roller 6 of the outer glass 5 is further supported at the four corners of the inner surface 5a of the outer glass 5 to prevent the inner glass 3 from sliding or coming into close contact with the outer glass 5 when the inner glass 3 and the outer glass 5 are in an overlapping position relationship. A stopper 14 is provided to prevent this, and handles 15 and 16 are provided protruding from the front and rear ends of the inner surface 5a. Then, the rollers 4, 4 of the inner glass 3 are brought into rolling contact with the lower guide path 1e of the sash 1 and the upper guide path 2b of the sash 2, and the cams 8 are fitted into the respective guide grooves 9, Further, the outer glass 5 is overlapped with the outer side of the inner glass 3, and each roller 6 of the outer glass 5 is brought into contact with the upper guide path 1b of the sash 1 and the lower guide path 2c of the sash 2, so that the inner glass 3 And an outer glass 5 is arranged so as to be movable in the front and rear directions relative to the sashes 1 and 2.

In the figure, 17 and 18 are seals, and when the inner glass 3 is closed and positioned on the same surface as the outer glass 5, that is, when the step is eliminated, the rear vertical edges 3d of the inner glass 3 and the outer glass 5 facing each other are In order to close the gap between the front vertical edge 5b and maintain airtightness and waterproofness, the vertical edge 3
d, attached along 5b. Reference numerals 1g and 2f are locking edges that are slightly erected in the vertical direction along the outer edges of the upper guide paths 1b and 2b to prevent the respective rollers 4 and 6 from coming off or meandering from their respective guide paths during rolling. This is to prevent internal and external glass from opening and closing smoothly.

Next, the operation of the present invention will be explained by moving both glasses to remove the step from the state where the outer glass 5 is located at the front and the inner glass 3 is located at the rear, creating a step, as shown in Figure 2a. To explain how the situation can be resolved, if you grasp the handle 12 of the inner glass 3 and apply a force in the forward direction, the pushing force will be applied to the respective leaf springs 10 and the mounting plate 1.
1 to the respective rollers 4, 4, the upper rollers 4, 4 roll on the lower guide path 1e, and the lower rollers 4, 4 roll on the upper guide path 2b, respectively. Once the plate spring 10 and the cam bracket 7 are moved forward halfway, they are stopped [second
Figure b]. At this time, a portion of the rear half of the window is opened.

Next, when gripping the handle 15 on the front side of the outer glass 5 and applying a force in the backward direction, the traction force is transmitted to each roller 6 via each bracket 13, and the upper roller 6 moves along the lower guide path 1b and Lower roller 6
The outer glass 5 is temporarily stopped at a position where the outer glass 5 is partially retracted so that the outer glass 5 rolls on the lower guide path 2c.
Figure c]. At this time, part of the front half of the window is opened.

When the inner glass 3 is pushed forward again, the inner glass 3 stops at the position where the front upper and lower cams 8 reach the ends of the upper and lower inner window grooves 9, and the part of the opening in the front half of the window is closed. , the positional relationship is such that the stopper 14 overlaps the outer glass 5 through the protruding interval (FIG. 2c). Further, as the inner glass 3 moves forward, the handle 15 on the rear side of the outer glass 5 is exposed, so grasp the handle 15 and pull it backward again to prevent the rear longitudinal edge of the outer glass 5.
When c is retreated to a position where it abuts against the rear longitudinal edge of the window frame, the rear opening of the window created by the advancement of the inner glass 3 is closed. At the same time, Stoppa 1
The inner glass 3, whose protrusion was suppressed by polymerization with the outer glass 5 through the inner glass 4, is released and pushed outward by the elasticity of the leaf spring 10, that is, toward the position before the outer glass 5 was moved. respective cams 8 provided via respective cam brackets 7 of the inner glass 3;
8 is also pulled outward, so the cams 8, 8 are pulled into the guide groove 9.
It is guided by the meandering grooves 9a, 9a communicating with the meandering grooves 9a, 9a, and is displaced outward and stops at the end of the meandering grooves 9a, 9a. The step difference between the outer surface 3e of the glass 3 and the front vertical edge 5b of the outer glass 5 is eliminated and they are aligned in a straight line, and the window is closed.

In addition to the above, in order to close the inner glass 3 without any difference in level with the outer glass 5, in the state shown in Fig. 2a, first move the outer glass 5 back to a position where it completely overlaps with the inner glass 3, and then close the front half of the window. , then open the inner glass 3
When closing the opening of the front half of the window by advancing the
First, open the rear half of the window by advancing the inner glass 3 to a position where it overlaps with the outer glass 5, and then pinch the rear vertical edge 5c and outer surface 5d of the outer glass 5 with multiple fingers to open the outer glass 5. In some cases, the rear opening of the window is closed by retreating, but in either case, the inner glass 3 protrudes due to the action and position of each member during movement, the mutual relationship, and the elasticity of the leaf spring 10 when closing. The effect of eliminating the level difference with the outer glass 5 is the same as described above.

Next, when opening the window from the state shown in FIG. 8 returns to the guide groove 9 side along the meandering grooves 9a, 9a, and the inner glass 3, which was on the same surface as the outer glass 5, is displaced toward the indoor side and becomes in a shifted positional relationship with the outer glass 5, and in this state, the inner glass 3 When the glass 3 is pulled halfway backwards, the rollers 4, 4 move along the lower guide path 1e and the upper guide path 2b, and the cam 8 moves backwards along the guide groove 9 together with the inner glass 3, pulling a part of the front half of the window. When the inner glass 3 is opened and further moved to a position where the rear vertical edge 3d of the inner glass 3 abuts the rear vertical edge of the window frame, the inner glass 3 is opened.
The positional relationship is such that the outer glass 5 is overlapped via the stopper 14, and the front half of the window is opened.

In addition, when opening the window, in addition to the above, from the state shown in Figure 2 d, the inner glass 3 is retreated halfway,
Next, by advancing the outer glass 5 partway and positioning it so that it overlaps with the inner glass, the first half and the second half of the window are opened one by one, and the inner glass 5 is opened with one hand.
When the outer glass 5 is moved inward and shifted from the outer glass 5, the outer glass 5 is advanced to a position where it overlaps the inner glass 3, and the second half of the window is opened. Then, when the inner glass 3 is all moved back, the second half of the window is closed. Even while the inner glass 3 and outer glass 5 are moving backward to close and open the window, the elasticity of the leaf spring 10 acts on the inner glass 3 to press the inner glass toward the outer glass 5. However, each cam 8 is pivotally supported on the inner glass 3 via each cam bracket 7.
The inner glass 3 slides on the upper and lower guide grooves 9, which are located on the indoor side of the upper and lower meandering grooves 9a and parallel to the guide paths on which the rollers 4, 4 of the inner glass 3 roll.
By moving in parallel with the guide grooves 9, 9, the elasticity is suppressed, and the inner glass 3 does not press or protrude against the outer glass 5 in an attempt to protrude outward, and the inner glass 3 does not push against the stopper. Since it is spaced from the outer glass 5 by 14, it does not come into close contact with the outer glass 5.
Since the outer glass is not subjected to the elastic force of the leaf spring, the rollers 6 of the outer glass 5 roll in the upper guide path 1b and the lower guide path 2c, respectively, without being displaced in the inward and outward directions. Furthermore, since a plurality of rollers are pivotally supported on each of the leaf springs 10, even if the elasticity of the leaf spring 10 acts on the other end 10b of the leaf spring 10, the rollers will not move against the lower guide path 1e or the upper guide path 2b. They do not roll in a twisted positional relationship and always roll parallel to each guideway plate surface.

Therefore, according to the present invention, when the sliding windows are closed, the difference in level between the inner glass and the outer glass is eliminated, so the appearance is good and there is no wind noise or air resistance while driving. In addition, leaf springs are installed at the four corners of the inner glass so that the elasticity of the leaf springs is applied evenly to the inner glass.At the same time, the cam installed on the inner glass via a cam bracket is slid along the guide groove and meandering groove. The protruding length of the inner glass is regulated by the elasticity of the leaf spring, so that even when the inner glass protrudes, it can be done evenly and smoothly. The elasticity of the spring prevents the roller from twisting against the rolling surface, so it always rolls smoothly parallel to the rolling surface, and the outer glass bracket does not interfere with the inner glass. Since the outer glass is installed with a stopper to maintain a distance between it and the inner glass, the inner glass can be moved smoothly and parallel to the upper and lower sashes and the outer glass. In addition, while the inner glass and outer glass are being moved forward and backward, the elasticity of the leaf spring provided on the inner glass is suppressed by the connection between the inner glass, cam bracket, cam, and guide groove, so that the leaf spring The inner glass, which is pushed toward the outer glass by elasticity, does not press against the outer glass, and the stopper provided on the outer glass prevents the inner glass from coming into close contact with the outer glass, causing the bracket to interfere with the inner glass. Coupled with the fact that the rollers for the outer glass roll smoothly on each guide path, the outer glass can be moved smoothly, and the inner and outer glass can be moved simultaneously without any problem. . In addition to the usual square windows of automobiles and other vehicles, this mechanism can also be used, for example, in parallelogram-shaped windows installed in mountain trams with parallelogram-shaped sides.
