It is known to form a display device by detachably locking a bracket having a locked portion such as a hooking piece formed in a detachable shape.

As a groove structure for detachably locking the bracket to the rail member, a locking device as shown in FIG. 4 is known, but the locking device shown in FIG. The rail member H mounted horizontally is provided with an opening groove 30a as a groove 30 having a laterally convex inner profile in a side cross section, and upper and lower engaging grooves 30b at the bottom of the opening groove 30a. On the other hand, the bracket B supported by the rail member H forms the locked portion 40 formed at the rear end of the arm member 41 while forming the 30c.
The front end 40b is engaged with the locking groove 30b through 30a, and a substantially L-shaped locked main member 40a on the side surface and a front end surface 30d of the opening groove 30a on the rear end side of the main member 40a. Abutting surface 40c
And a fitting protrusion 4 that fits into the entrance of the opening groove 30a and holds its position.
And 0d. C is the above
The cover member is attached to the hook member H by a hook-and-loop fastener f, an adhesive material, or a male and female engaging structure.

In the bracket B, when the arm member 41 is slightly lifted in the counterclockwise direction from the position shown in FIG. 5, the tip 40b of the locked main member 40a is disengaged from the locking groove 30b and the contact surface Since the 40c is separated from the front end surface 30d of the groove 30a, and the fitting protrusion 40d is separated from the inlet of the opening groove 30a, it can be easily removed. If a force from the bottom to the top of the member 41 is accidentally applied to the member 41, there is a problem that the bracket B falls off from the locking portion of the rail member H.

In view of this point, for example, the above-mentioned fitting protrusion 40
A detachment prevention structure such as forming a large d to make it difficult to detach is also conceivable, but it is preferable to simply form the fitting protrusion 40d tightly with respect to the receiving portion because the detaching operation becomes heavy. Not a solution.

Here, FIG. By forming an opening groove 1 having substantially the same cross-sectional shape as that of the illustrated conventional product on the front surface, and forming locking grooves 2 and 3 extending upward and downward on the bottom of the opening groove 1, it is possible to substantially reduce the side view. While forming a laterally convex inner contour-shaped locking portion, a horizontal support wall 4 is formed on the lower surface. The sectional shape of the locking portion to which the present invention can be applied is not limited to the exemplified one.

That is, in the above embodiment, the locking portion of the rail member H has a vertically symmetrical sectional shape with respect to the center of the opening groove 1. However, the locking of the rail member H to which the present invention can be applied is performed. The shape of the part is not limited to that shown in the figure, and the cross-sectional shape and other parts of the other part as long as it includes the opening groove 1 and the locking grooves 2 or 3 connected to the opening groove 1 and the substantially horizontal support wall 4 on the lower surface. The material and the like may have other shapes and materials. Reference numeral 5 denotes a support wall on the upper surface side of the rail member at a position symmetrical to the support wall 4.

In the rail member H, 1a and 1b are standing pieces that form the opening groove 1, and 2a and 3a are locking grooves 2 and 3 that are formed at right angles on the lower ends of the standing pieces 1a and 1b. A front wall 6 is a base plate of the rail member H attached to the wall surface W, and its front surface 6a forms rear walls of the locking grooves 2 and 3. The pieces 1a, 1b and the walls 2a, 3a, 6a may be integrally formed by drawing, extruding, or the like, or may be separately formed and then formed in the cross section by joining or the like later. .

In the rail member H, C is a cover having a substantially L-shaped cross section which is mounted between the upper and lower support walls 5 and 4 and the upright pieces 1b and 1a of the opening groove 1, respectively. In the member, C1 is a sandwiching wall that sandwiches the support walls 4 and 5, and C2 is an abutment wall that abuts against the back surface of the standing piece 1a or 1b. A convex portion 7 described later is formed on the lower surface or the upper surface of the cover member C. It should be noted that the convex portion 7 is formed before and after the rising of the convex portion 7,
It is formed on the curved surface rising portions 7a and 7b having an appropriate curvature. Also,
The convex portion 7 is formed linearly over the entire length of the cover member C, that is, the entire length of the rail member H, but is a mode in which the dot-shaped convex portions 7 are arranged in a line. Good.

On the other hand, the bracket B is the arm member 8 here.
And a horizontal locked base portion 9a provided at the rear end thereof and the piece 9a.
A substantially L-shaped locked piece is provided by a hooking piece 9b which is erected at the rear end of the base wall 9a, and a standing wall surface 9c hanging down from the front end of the base portion 9a and a lower end of the standing wall surface 9c are horizontally oriented backward. It is formed by the locked portion 9 which is provided with the horizontal surfaces 9d that are continuously provided. Then, the locked base portion 9a, the standing wall surface 9c, the horizontal surface 9d
Constitutes a holding piece for sandwiching the upstanding wall 1b and the support wall 4 below the opening groove 1 of the rail member H from above and below them. Also,
At the tip of the horizontal surface 9d, a sandwiching piece 10 made of a round bar member is provided here. When the convex portion 7 has a linear shape, the holding piece 10 may be a sphere with a proper radius, or a short cylinder or a short rod body, but the convex portions 7 are arranged in a dot shape. When it is a thing, a long round bar shape or a cylindrical member is desirable. In the present invention, the hooking piece 9b of the bracket B may face downward.

10, the locking groove 2, the opening groove 1 and the convex portion 7 of the rail member H
And the bracket B cooperate with each other to realize a state in which the bracket B is easily, surely and firmly attached to the rail member H. When the bracket B is attached or detached, the rising portions 7a and 7b having a curvature of the convex portion 7 have a role of smoothing the overcoming operation of the sandwiching piece 10 that rides over the convex portion 7.

That is, in order to mount the bracket B on the rail member H, the engaged portion 9 is placed in the posture shown by the chain line in FIG. 2, and the tip end side of the hooking piece 9b is attached to the rail member H. A state in which the locked base portion 9a is allowed to enter the locking groove 2 through the opening groove 1 is brought into a state in which the locked base portion 9a obliquely abuts against the standing wall 1b of the opening groove 1.

When the lower half side of the locked portion 9 is rotated clockwise from the above posture in the clockwise direction in FIG. 2, the standing wall surface 9c becomes parallel to the lower cover member C, and at the same time, it is provided at the tip of the horizontal surface 9d. The round bar-shaped holding piece 10 rides over the convex portion 7 of the cover member C and is settled between the wall surface W and the convex portion 7.

At this time, the locked base portion 9a and the horizontal surface 9d elastically hug or sandwich the upright piece 1b of the opening groove 1 of the rail member H and the support wall 4 from above and below thereof. Becomes As a result, the sandwiching piece 10 that is fitted between the wall surface W and the convex portion 7 beyond the convex portion 7 is held at that position via the elastic force, so that the bracket is tentatively used. Even if an external force is accidentally applied to the arm member 8 of B from below, there is no danger of the arm member 8 coming off easily. Therefore, when removing this bracket, the arm member 8 is lifted up with a little strong force to remove the holding piece.
It can be easily removed by overcoming the convex portion 7 on 10.

In the above embodiment, the convex portion 7 is covered.
The rail member H is formed on the outer surface of the member C, but the cover member C is not provided, or even if the cover member C is provided, the cover member H does not cover the outer surface of the support wall 4. In this case, the convex portion 7 is directly formed on the outer surface of the support wall 4. As described above, the convex portions 7 provided on the rail member H are also arranged in a line or in a dot shape over the entire length thereof.

Also, the arm member 8 of the bracket B of the embodiment
Is an arm member having a downward plate shape,
The bracket B to which the present invention can be applied has a length of the arm member 8,
Alternatively, the angle projecting from the locked portion 9 is not limited to that of the embodiment, and any other arbitrary length or angle may be applied. Reference numeral 8a denotes a hanger hooking pin provided on the upper surface of the arm member 8.
