Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure welding device for attaching a pressure welding member to the upper and lower ends of a moving wall and fixing the moving wall.

[0002]

[Prior art]

 There are various types of pressure welding devices for overhanging the pressure welding members attached to the upper and lower ends of the moving wall. One is when the upper and lower pressure contact members are extended by operating the handle or lever, and the other is provided with a horizontally arranged rod, and a bush is screwed at the tip of the rod. Partly protruding from the side edge of the moving wall, and the bush is brought into contact with the wall rail of the building or the end surface of the adjacent moving wall and retracts to automatically extend the pressure welding part. is there.

In this pressure contact device, a swing link is connected to the horizontal rod, and the horizontal movement of the horizontal rod moves the pressure contact rod up and down through the swing link, and the pressure contact member is attached to the pressure contact rod. It is a thing. FIG. 4 shows a conventional pressure welding device. The horizontal rod (a) can be horizontally moved by being supported by the supporting plates (b) and (b), and the horizontal rod (a) can be supported by the horizontal movement. The link (d) swings around the shaft (c) provided on the plate (b).

Therefore, if the horizontal rod (a) moves to the left, the link (d) rotates counterclockwise about the axis (c), and the pressure welding rod connected to the end of the link (d). (E) descends, and the pressure contact member (not shown) attached to the lower end of the pressure contact rod (e) also descends. The bush (f) screwed onto the end of the horizontal rod (a) projects from the side edge of the moving wall, and this protruding part moves backward when it contacts the wall rail and moves the horizontal rod (a) to the left. Let The leftward movement of the horizontal rod (a) lowers the pressure contact member, but when the coil spring (g) is compressed and the moving wall is moved, the spring force of the coil spring (t) causes the horizontal rod (a) and the pressure contact member to move. It returns to its original position and the bush (f) projects again.

By the way, by connecting the pressure contact rod (e) to the tip of the link (d) that swings about the shaft (c), the pressure contact rod (e) can move up and down, Since the movement of the link (d) is a swinging movement, the pressure contact rod (e) is accompanied by horizontal movement. Therefore, since the pressure contact member also moves horizontally as it moves up and down, it is not possible to install a pressure contact member with the full width of the moving wall, and inevitably a gap remains between the pressure contact members of the adjacent moving walls. In the pressure contact state, it is bent by the horizontal motion acting on the pressure contact rod (e), so that an unreasonable force acts on the link (d), its shaft (c) and the support plate (b), and the pressure contact device itself This results in rattling.

Of course, in place of the swing link (d), a slider that horizontally moves together with the horizontal rod (a) is provided, and an inclined groove is formed in this slider, and the inclined groove of the pressure contact rod (e) is formed in the inclined groove. If the upper end is guided and the pressure contact rod (e) is constrained by a guide that can only move up and down, horizontal movement of the pressure contact rod (e) and the pressure contact member will not occur. However, if such a mechanism is used, its structure is more complicated than that of the above-mentioned link mechanism, and its frictional resistance is large when moving along an inclined groove or a vertical guide. The force that presses (or the lower end) also generates a bending moment in the pressure contact rod.

[0007]

[Problems to be solved by the present invention]

 As described above, the conventional bush type pressure welding device has the above problems. The problems to be solved by the present invention are these problems, and the pressure contact rod can only move up and down, thus eliminating the horizontal movement of the pressure contact member attached to the pressure contact rod, and consequently the adjacent movement. (EN) Provided is a pressure welding device which does not cause a gap between a wall and a pressure welding member.

[0008]

[Means for Solving the Problems]

 The bush type press contact device of the present invention is a mechanism for moving the press contact rod up and down by using a horizontal rod and a swing link as in the conventional case, but in the present invention, an auxiliary link is used in addition to the above swing link. . Here, a long hole is formed at the tip of the swing link, and the end of the pressure contact rod is loosely fitted in this long hole, and the auxiliary link also swings about another fulcrum. It is connected to the end of the crimping rod. Then, a long hole is formed on the side of the fulcrum shaft which is the swing center of the auxiliary link, and the fulcrum shaft is loosely fitted in the long hole.

In this case, if the swinging link swings, the swinging fulcrum can be changed by the end of the pressure contact rod connected to the tip of the auxiliary link along the elongated hole formed at the tip and the auxiliary link itself. To move along the long hole. Therefore, the end of the pressure contact rod is not necessarily forced to move up and down, but if the pressure contact member has a simple guide, it can only move up and down without horizontal movement. However, if the oscillating distances of the oscillating link and the auxiliary link are made equal, a long hole is formed at the tip of each link, and the ends of the pressure welding rods are guided in both long holes, the pressure welding rods will move upward and downward You can move by being restrained by. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 shows an embodiment of the bush type pressure welding device of the present invention. In the figure, 1 is a horizontal rod, 2 is a swing link, 3 is an auxiliary link, and 4 and 5 are support plates. As shown in FIG. 4, the horizontal rod 1 is provided on a lower end and an upper end of the moving wall, or on a lower end of an opening / closing door attached to the moving wall, and a supporting frame 6 fixed to the moving wall. It is attached and allows horizontal movement. The support frames 6, 6 are provided at two places with a predetermined distance to support the long horizontal rod 1, and the support frames 6 are provided with support plates 4, 5. A swing link 2 is swingably attached to a support plate 4 about a shaft 7, and an auxiliary link 3 is swingably attached to a support plate 5 about a shaft 8.

Here, the swing link 2 swings along with the horizontal movement of the horizontal rod 1, but a pin 9 provided on the horizontal rod 1 loosely fits into a long hole 10 of the swing link 2. There is. A long hole 11 is formed in the auxiliary link 3, and the swing radius of the auxiliary link 3 changes within the range of the long hole 11 by loosely fitting the shaft 8 in the long hole 11. A pressure contact rod 12 is connected to a shaft 13 provided at the other end of the auxiliary link 3, and the shaft 13 is loosely fitted in a long hole 14 formed at the tip of the swing link 2. A pressure contact member (not shown) is attached to the lower end of the pressure contact rod 12, and a coil spring 16 is provided on the pressure contact rod 12 so that the pressure contact member closely contacts even if the floor surface is undulated.

FIG. 2 shows the movements of the swing link 2 and the auxiliary link 3. If the swing link 2 rotates counterclockwise about the shaft 7 as the horizontal rod 1 moves leftward, For example, the shaft 13 at the upper end of the pressure contact rod 12 descends. Since the shaft 13 is loosely fitted in the long hole 14 at the tip of the swing link 2, its position is not fixed, and the position of the shaft 8 loosely fitted in the long hole 11 of the auxiliary link 3 with respect to the long hole 11 is not fixed. Change. When the swing link 2 and the auxiliary link 3 are rotationally moved to the position shown by the alternate long and short dash line, the shaft 13 and the shaft 8 are located substantially in the middle of the elongated holes 14 and 11.

Further, when the swing link 2 is rotated to be as shown in FIG. 2B, the distal end long hole 14 of the swing link 2 is located on the leftmost side, and the auxiliary link 3 is also moved to the left side. Therefore, the shaft 13 moves to the right end of the long hole 14, and the shaft 8 moves to the right end of the long hole 11. Here, if the shaft 13 of the swing link 2 shown by the solid line a is set to the top dead center and the positions of the shaft 13 and the shaft 8 in the long holes 14 and 11 are set to the left end, b The position of the bottom dead center axis 13 indicated by is defined on the same Y-Y axis. Of course, between the top dead center and the bottom dead center, the positions of the shaft 13 and the shaft 8 are not constrained to a fixed position, but since an external force in the lateral direction does not act, the shaft 13 provided at the upper end of the pressure welding rod 12 is Y -Descent along the Y axis. The same applies when this pressure welding device is attached to the upper end of the moving wall.

FIG. 3 shows another embodiment of the swing link 2 and the auxiliary link 3 of the present invention, in which the length of the auxiliary link 3 is made longer and the rotation radius about the shaft 7 of the swing link 2 is shown. The turning radii about the axis 8 of the auxiliary link 3 are made equal. The inclinations (Q) and (Q) of the links 2 and 3 with respect to the Y-Y axis are always the same, slots 14 and 15 are formed at the tips, and the shaft 13 has both slots 14 and 15. It is loosely fitted in 15.

Of course, since there is a slider guided in both the long holes 14 and 15 without rattling, and the shaft 13 is provided in this slider, the rotation radii of both the links 2 and 3 are If the inclinations (Q) are made equal, the shaft 13 is always located on the YY axis regardless of the rotation angles of the swing link 2 and the auxiliary link 3. Therefore, the pressure rod 12 can always move up and down along the Y-Y axis. As described above, the bush-type pressure contact device of the present invention uses the swing link and the auxiliary link that swing with the horizontal movement of the horizontal rod, and the following effects can be obtained.

[0016]

[Effect of device]

 The bushing type pressure welding device of the present invention uses an auxiliary link in addition to the swinging link that swings with the horizontal movement of the horizontal rod, so that the pressure welding rod can be moved up and down without moving laterally. Therefore, since the pressure contact member attached to the pressure contact rod does not move horizontally, no gap is left between the pressure contact members of the adjacent moving walls in the pressure contact state. Of course, the degree of airtightness between the floor and the ceiling is also high. In addition, when the floor surface is not flattened, the coil spring provided on the pressure-contact rod adjusts the gap, leaving no gap between the pressure-contact member and the floor surface.
