In the position. The support portion 5e is formed by bending the side walls 5c and 5d toward the inner side in the width direction. Further, the support portion 5e supports the slider 7 at the rear side portions 7ce and 7de, wherein the rear side portions 7ce and 7de are located outside the slider suspension portion 7a in the width direction. As shown in Fig. 7, in a state where the upper beam 1 is supported by the main body hanging portions 5ac, 5ad and the slider hanging portion 7a, the bottom surfaces of the rear side portions 7ce, 7de are substantially the same as the rear end edge 1b of the upper beam 1. Height.

The slider 7 is provided with a temporary fixing arm 7f, the temporary fixing arm The temporary fixing protrusion 7g which protrudes toward the outer side of the width direction is provided in the 7f. As shown in FIG. 3, the temporary fixing protrusion 7g is provided with the top side taper surface 7ga which becomes the outer side of the width direction. The bracket main body 5 is provided with a temporary fixing locking portion 5g, and the distance between the main body hanging portions 5ac, 5ad and the slider hanging portion 7a is longer than the distance after the upper beam 1 is supported as shown in FIG. Temporary fixed card The fixed portion 5g locks the temporary fixing protrusion 7g.

As shown in FIG. 3, the temporary fixing locking portion 5g is provided on the front side thereof. The front tapered surface 5gf of the temporary fixing protrusion 7g is guided toward the inner side in the width direction, and the tapered surface 5ct toward the inner side in the width direction is provided on the top surface of the rear side slit 5cu on the rear side of the temporary fixing locking portion 5g. Furthermore, as shown in Fig. 3, the temporary fixing protrusion 7g is provided with a front side locking surface 7gc that is locked to the temporary fixing locking portion 5g on the front side thereof, and a side tapered surface 7gb that is inclined toward the inner side in the width direction on the rear side. On the lower side, a lower side protrusion 7gu is protruded toward the lower side.

As shown in FIG. 4, a housing coil spring 9 is provided on the slider 7. The coil spring housing portion 7i extends forward from the rear side portion 7de of the slider 7. As shown in Fig. 6(d), a groove 7j having a smaller width than the diameter of the coil spring 9 is provided on the bottom surface of the coil spring housing portion 7i. By providing such a groove 7j, it is possible to prevent the coil spring 9 from coming off, and it is possible to use the coil spring 9 having a large diameter as much as possible. The bracket body 5 is provided with a coil spring abutting portion 5i that protrudes from the top wall 5b toward the inside of the coil spring housing portion 7i.

Next, the assembly method of the mounting bracket 3 of the present embodiment Be explained.

First, as shown in Figures 5(a) to (b), prepare the bracket body. 5. The slider 7 and the coil spring 9 are housed in the coil spring housing portion 7i of the slider 7.

Next, as shown in Figures 5(c) to (d), the rear of the slider 7 The side side portions 7ce, 7de are inserted between the support portion 5e of the bracket body 5 and the top wall 5b. At this time, one end of the coil spring 9 is abutted on the coil spring abutting portion 5i. on.

Then, the slider 7 is pushed in this state, and the engaging convex portion 7c, The 7d is engaged in the slide holes 5cs and 5ds, and becomes the state shown in Figs. 5(e) to (f), thereby completing the assembly of the mounting bracket 3. Since the engaging convex portions 7c and 7d are engaged with the sliding holes 5cs and 5ds from the lower side of the bracket main body 5 beyond the side walls 5c and 5d, in order to reduce the force required for the engaging, as shown in FIG. Conical surfaces 7ct and 7dt which become lower toward the outer side in the width direction are formed on the upper side surfaces of the engaging convex portions 7c and 7d.

In addition, as shown in FIG. 4, the engaging convex portions 7c, 7d are provided at The slider 7 is provided on the double side support arms 7ca, 7da. Since the engaging convex portions 7c, 7d are provided on the double side supporting arms 7ca, 7da instead of the one side supporting arms, pressing the engaging convex portions 7c, 7d toward the inner side in the width direction requires a relatively large force, whereby the card The convex portions 7c and 7d are less likely to fall off from the sliding holes 5cs and 5ds. Therefore, the engaging convex portions 7c and 7d function as a supporting portion that supports the slider 7. In the prior art, although the engagement convex portion is provided on the one-side support arm, such an engagement convex portion can be pushed toward the inner side in the width direction by a small force, and thus cannot function as a support portion.

Next, the side in which the upper beam 1 is mounted in the mounting bracket 3 The law is explained.

First, as shown in Figure 6, before installing the upper beam 1, facing The slider 7 is pushed in the rear side direction of the bracket main body 5, and the temporary fixing projection 7g is engaged with the temporary fixing locking portion 5g. Thereby, the slider 7 is temporarily fixed, and the slider hanging portion 7a is held away from the main body hanging portions 5ac, 5ad. In more detail, when the slider 7 is pushed toward the rear side of the bracket body 5, Initially, the rear tapered surface 7gb shown in Fig. 3 abuts against the front tapered surface 5gf of the temporary fixing locking portion 5g. When the pushing is continued in this state, the temporary fixing arm 7f is elastically deformed, and the temporary fixing projection 7g is The inner side of the width direction is pushed to enter the inner side of the side wall 5c, and when the slider 7 is further pushed in this state, the temporary fixing protrusion 7g passes over the temporary fixing locking portion 5g and enters the rear side slit 5cu.

Then, the front side locking surface 7gc of the temporary fixing protrusion 7g is temporarily fixed The card is fixed on the temporary fixing locking portion 5g. Although the slider 7 is biased by the coil spring 9 in a direction away from the bracket body 5, since the front side locking surface 7gc is locked by the temporary fixing locking portion 5g, the slider 7 can be prevented from moving forward. Further, the slider 7 is provided with a small projection 7k on the side opposite to the temporary fixing projection 7g, and the projection 7k abuts against the side wall 5d of the bracket main body 5, thereby reducing the slider 7 in the width direction with respect to the bracket The frame main body 5 is shaken, thereby preventing the temporary fixing protrusion 7g from coming off the temporary fixing locking portion 5g.

Next, as shown in FIGS. 6 to 7, the front edge of the upper beam 1 is 1a is supported in the main body suspension portions 5ac, 5ad, and the rear side of the upper beam 1 is lifted upward, thereby supporting the rear end edge 1b of the upper beam 1 in the slider hanging portion 7a. At this time, the top surface 1e on the rear side of the upper beam 1 abuts on the lower side protrusion 7gu located on the lower side of the temporary fixing protrusion 7g, and pushes the temporary fixing protrusion 7g upward. As shown in FIG. 3, the upper side surface of the temporary fixing protrusion 7g is provided with a top side tapered surface 7ga which becomes lower toward the outer side in the width direction, and therefore, when the temporary fixing protrusion 7g is pushed upward, the temporary fixing protrusion 7g is Squeezing toward the inner side in the width direction to enter the inner side of the side wall 5c, thereby causing the front side locking surface 7gc and the temporary solid The engagement of the fixed locking portion 5g is released. Thereby, the slider 7 moves in a direction away from the bracket main body 5 by the urging force of the coil spring 9, whereby the distance between the main body suspension portions 5ac, 5ad and the slider hanging portion 7a becomes short, so that As shown in Fig. 7, the upper beam 1 is held between the main body suspension portions 5ac, 5ad and the slider hanging portion 7a.

In addition, since the top surface of the rear side slit 5cu is provided with an orientation Since the tapered surface 5c which becomes the inner side of the width direction is in contact with the side wall 5c, the wear of the top side taper surface 7ga can be reduced, and the temporary fixing protrusion part 7g is easy to move in the width direction inner side. Further, since the front tapered surface 5gf is provided on the front side of the temporary fixing locking portion 5g, the temporary fixing protruding portion 7g is easily released from the state of being pushed toward the inner side in the width direction, and returns to the state shown in Fig. 3(c). Enter the state inside the front side slit 5cf.

On the front side of the slider 7, the engaging projections are supported by the sliding holes 5cs, 5ds On the rear side of the portions 7c, 7d, on the rear side, the rear side portions 7ce, 7de are supported by the support portion 5e. Since most of the load from the upper beam 1 is applied to the rear side of the slider 7 via the slider hanging portion 7a, even in the region 1c opposed to the top surface of the upper beam 1, no other side wall of the bracket body 5 is oriented. The support portion formed by projecting inward in the width direction does not fall off the slider 7.

Here, according to FIGS. 8 to 9 , the upper beam 1 is mounted to the installation. The state of the front end edge 1a of the upper beam 1 and the main body hanging portions 5ac and 5ad in the bracket 3 will be described in detail.

As shown in Fig. 8(a), the front edge 1a of the upper beam 1 is front The end protrudes downward, and the front end edge projecting portion 1at is locked by the locking portion 5tc of the first main body hanging portion 5ac. Thereby, the front edge 1a is supported on the main body In the temporarily fixed state in which the hanging portions 5ac, 5ad and the rear end edge 1b are not supported by the slider hanging portion 7a, the front end edge 1a can be prevented from falling off from the main body hanging portions 5ac, 5ad.

a first main body suspension portion of the two main body suspension portions 5ac, 5ad The locking portion 5tc is provided in the 5ac. However, as shown in Fig. 8(b), the locking portion 5tc is not provided in the second main body hanging portion 5ad. Therefore, the front end edge 1a of the upper beam 1 is not restricted in the second main body hanging portion 5ad, and can be moved in the direction indicated by the arrow A in Fig. 8(b).

In the direction of the front and rear of the two mounting brackets 3 as shown in FIG. In the case where only the distance d is shifted, the relative position of the front end edge 1a with respect to the first main body hanging portion 5ac is maintained at the position shown in Fig. 8(a), and the relative position of the front end edge 1a with respect to the second main body hanging portion 5ad is set. It can be changed as shown in Fig. 8(c). Therefore, even in the state shown in FIG. 9, the front end edge 1a can be supported by the main body suspension parts 5ac and 5ad without any problem, and the workability is excellent.

In addition, the rear end edge 1b is supported on the slider hanging portion 7a After that, as shown in FIG. 8(d), the front end edge 1a is supported by the first main body hanging portion 5ac, and as shown in FIGS. 8(e) to (f), the front end edge projection 1at of the front end edge 1a is second. The main body suspension portion 5ad is supported. Thereby, since the front end edge 1a of the upper beam 1 is supported by the main body suspension parts 5ac and 5ad, stability is excellent.

As described above, in the present embodiment, since only the main body is suspended The main body suspension portion of the hanging portions 5ac and 5ad is provided with the locking portion 5tc, so that the workability and stability are excellent.

2. Second embodiment

A second embodiment of the present invention will be described based on Fig. 10 .

In the present embodiment, the lengths of the main body hanging portions 5ac and 5ad and the front end edge 1a in the front-rear direction are longer than those of the first embodiment. Therefore, as shown in FIG. 10(a), even in a state where the front end edge 1a is supported by the main body hanging portions 5ac, 5ad, the front end edge 1a can be moved by the distance S in the front-rear direction. In the state of the art, in a state where the front end edge 1a is supported on the main body hanging portions 5ac, 5ad, the range in which the front end edge 1a can move in the front-rear direction is usually about 0.5 times the thickness of the plate. In the present embodiment, the movable distance S is set to be more than one time the plate thickness T of the leading edge 1a, whereby even the position at which the bracket 3 is mounted as shown in FIG. 9 is shifted by the distance d in the front-rear direction. In this case, the front end edge 1a can also be easily supported on the main body hanging portions 5ac, 5ad. From the viewpoint of the workability, the larger the value of S/T, the better, but since the value is larger, the length of the mounting bracket 3 protruding from the upper beam 1 toward the indoor side is larger, thereby impairing the appearance, and thus it is preferable. Do not exceed the required value. From the viewpoint of workability and aesthetics, the value of S/T is preferably from 1 to 3, more preferably from 1.5 to 2.5.

In the present embodiment, as shown in FIG. 10, the locking portion 5tc is also provided on the second main body hanging portion 5ad, but the relative position of the front end edge 1a with respect to the second main body hanging portion 5ad can be as shown in FIG. Since c) changes as shown, the upper beam 1 can be easily attached even when the position of the mounting bracket 3 is shifted in the front-rear direction.

In addition, in the present embodiment, it is also preferable to only be in the first body. A locking portion 5tc is provided on the hanging portion 5ac. This is because, in this case, it is not necessary to change the length of the mounting bracket 3 protruding from the upper beam 1 toward the indoor side, and the workability can be improved.

Further, the temporary fixing arm 7f is bent upward at the curved portion 7fk. The temporary fixing protrusion 7g is set in comparison The bent portion 7fk is closer to the front end side in the extending direction of the temporary fixing arm 7f. A lower protrusion 7gu that protrudes toward the lower side is provided at a position adjacent to the temporary fixing protrusion 7g.

In addition, as shown in FIG. 13, it is disposed on the bracket body 5. The front side tapered surface 5gf that guides the temporary fixing protruding portion 7g upward is provided on the front side of the temporary fixing locking portion 5g, and the rear side tapered surface 7gb is provided on the side of the temporary fixing protruding portion 7g that abuts against the front tapered surface 5gf. . Further, a rear side locking surface 5gb is provided on the rear side of the temporary fixing locking portion 5g, and a front side locking surface 7gc is provided on the front side of the temporary fixing protruding portion 7g.

Next, the side in which the upper beam 1 is mounted in the mounting bracket 3 The law is explained.

First, in the state shown in Figure 13 (i.e., temporarily fixed When the protruding portion 7g is located in the front side slit 5cf) when the slider 7 is pushed toward the rear side, the rear tapered surface 7gb of the temporary fixing protruding portion 7g abuts against the front tapered surface 5gf of the temporary fixing locking portion 5g, and is further oriented. When the slider 7 is pushed in the rear direction, the temporary fixing protrusion 7g passes over the temporary fixing locking portion 5g, and the state shown in Fig. 15 (a) is obtained. The slider 7 is always biased by the coil spring 9 in the direction of the front side. However, since the front side locking surface 7gc of the temporary fixing protrusion 7g abuts against the rear side locking surface 5gb of the temporary fixing locking portion 5g, it is possible to The slider 7 is prevented from moving toward the front side. Thereby, the slider 7 is temporarily fixed. In this state, the temporary fixing protrusion 7g is located in the rear side slit 5cu.

Next, as shown in FIGS. 15(a) to (b), the upper beam 1 is The front end edge 1a is supported in the main body hanging portions 5ac, 5ad and lifted up The rear side of the beam 1 supports the rear end edge 1b of the upper beam 1 in the slider hanging portion 7a. At this time, the top surface 1e on the rear side of the upper beam 1 abuts against the lower side protrusion 7gu and pushes up the temporary fixing protrusion 7g upward. After the temporary fixing protrusion 7g moves upward and the engagement between the front side locking surface 7gc and the rear side locking surface 5gb is released, the slider 7 moves toward the front side by the urging force of the coil spring 9, thereby causing the main body The distance between the suspension portions 5ac, 5ad and the slider hanging portion 7a becomes small, whereby the upper beam 1 is held between the main body suspension portions 5ac, 5ad and the slider hanging portion 7a as shown in Fig. 15 (b). .

The mounting bracket 3 in the above embodiment can also pass through the following Form implementation.

The vertical wall 5h is not a necessary component and can be omitted.

In the above-described embodiment, the main hanging portions 5ac and 5ad are formed by the inner hanging type supporting the front end edge 1a from the front-rear direction. However, the main hanging portions 5ac and 5ad may be formed to support the front end edge 1a from the front-rear direction. .

It is also possible to simultaneously provide the locking portions 5tc on the two main body hanging portions 5ac, 5ad.

It is not necessary to perform the temporary fixing of the slider 7, and thus the temporary fixing arm 7f and the temporary fixing protrusion 7g are not essential parts.
