DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of a mounting bracket according to the present invention will be described with reference to the drawings. In the following embodiment, all the opposing surfaces of the mounting bracket and the lever portion of the claw member have a symmetrical configuration. Therefore, only one opposing surface, that is, the side surface and one lever portion will be described unless otherwise specified.

FIG. 2 is a perspective explanatory view of the mounting bracket according to the present invention, and FIG. 1 is an exploded explanatory view thereof. First, reference numeral 1 denotes a first mounting member, which is vertically bent in a U-shape and has a total of three surfaces, namely, a side surface 1a and a mounting surface 1b. Mounting surface 1b
Are provided with a plurality of screw holes 1c, 1c,... For attaching furniture and the like, and have a U-shaped notch 1d at the rear of the side surface 1a (upper right direction in FIG. 1). Mounting surface 1b of first mounting member 1
Above the side surface 1a, a second U-shaped mounting member 2 is provided. The mounting surface 2b of the second mounting member 2 is
a, the mounting surface 1b of the first mounting member 1
Similarly, screw holes 2c, 2c,... Are provided. The second mounting member 2 overlaps the first mounting member 1 with its open side facing each other so that the side surfaces of the second mounting member 2 face outward. Further, the shaft hole 1e provided at the rear and the shaft hole 2e provided at the central root of the side surface 2a of the second mounting member 2 are aligned, and both side surfaces are pivotally mounted by passing the pin 4 so as to be rotatable. Here, when the angle (assumed as angle A) between the mounting surfaces 1b and 2b is 90 degrees, the mounting surface 2b of the second mounting member 2 is attached to the rear end 1f of the side surface 1a of the first mounting member 1. It is in contact with and cannot rotate more than 90 degrees, that is, does not rotate more than the use position.

On the other hand, a claw member 3 is provided above the first mounting member 1 and in front of the second mounting member 2 (the lower left direction in FIG. 2).
The claw member 3 includes a lever portion 3a, a side surface 3d, and side surfaces 3d.
Are provided with a side connecting portion 3c, a side surface 3d, and a lever portion 3a. The front half of the lever portion 3a has a gentle upward curve to improve the operability and appearance of the claw member 3. The claw member 3 is opened in the direction facing the mounting surface 2b of the second mounting member 2 at the use position by aligning the shaft hole 3e formed in the side surface 3d with the shaft hole 1g of the side surface 1a of the first mounting member 1. The rotation axis 2z of the second mounting member 2
Is pivotally mounted on a pin 5 so as to be rotatable on a rotation shaft 3z parallel to the shaft. Here, the second mounting member 2 is not allowed to rotate in a range narrower than the folding position so as to abut on the claw member 3 at the folding position (see FIG. 3). Claw member 3
The rotation range of the lever portion 3a is approximately 20 degrees at an angle (referred to as an angle B) between the first mounting member mounting surface 1b and the rear half 3f of the lever portion 3a with respect to the first mounting member side surface 1a depending on the contact state. The angle is limited to about 40 degrees from 60 degrees to 60 degrees. Note that the angle between the first mounting member mounting surface 1b and the side surface connecting portion 3c is set to an angle B plus about 20 degrees.

In addition, the side connecting portion 3c is urged so as to urge the claw member 3 in a direction parallel to the mounting surface 1b of the first mounting member 1.
A spring 7 is provided between the center and the rear center of the first mounting member 1.
Are provided via the spring holes 3g and the projection holes 1h (see FIG. 1), respectively, so that the angle B of the claw member 3 is made as small as possible unless an external force acts, and the claw member 3 attempts to maintain a state of approximately 20 degrees. The strength of the stress of the spring 7 is set such that the lever 3a of the claw member 3 can be rotated by a finger when installed, without requiring much force.
The stress is eliminated when it is fitted into the deepest part 6b (see FIG. 1) and when it is not in contact with the side surface 2a of the second mounting member 2. A claw fitting portion 6 with which the claw member 3 can abut is provided on the outer periphery of the side surface 2 a of the second mounting member 2. The shape of the claw fitting portion 6 is a rounded V-shape, and the angle between both mounting members is 90 °.
When the angle B is reached, the outer rear portion 3b in which the angle B is the smallest (approximately 20 degrees) is fitted into the deepest portion 6b. That is, in this case, the rear half 3f of the lever portion 3a directly supports both mounting members. With the above configuration, the claw fitting portion 6 serves as a locked portion, and the spring serves as a biasing means.

The operation and effect of the mounting bracket having the above configuration will be described again below. When the second mounting member 2 is operated from the folded position (see FIG. 3) to the use position in order, the claw member 3 will rotate without contacting the second mounting member 2 at a certain point ( Angle A is approximately 50
The lower surface of the lever portion 3a of the claw member 3 is
Starts to abut on the outer peripheral upper portion 2f (the upper right portion in FIG. 3) of the side surface 2a (see FIG. 4), and slides toward the claw fitting portion 6 in the direction in which the outer peripheral rear portion 3b of the lever portion 3a approaches. At this time, the angle B is increased by the shape of the outer peripheral upper portion 2f of the second mounting member 2 and the rotation of the second mounting member 2, the spring 7 is extended, and the claw member 3 is urged to move the second mounting member 2 to the second mounting member 2. Although it is pressed, it slides in the surface contact of the rear half 3f rear surface of the lever portion 3a with the outer peripheral upper portion 2f of the second mounting member 2, so that it does not significantly affect the force for actuation and is therefore easy. It can be rotated and has high durability.

When the angle A becomes vertical, the outer peripheral rear portion 3b of the lever portion 3a reaches the upper corner 6a of the rounded claw fitting portion 6 and comes out of the sliding state.
By the action of (1), the first attachment member 1 and the side surface connection portion 3c of the claw member 3 are fitted into the deepest portion 6b in a posture in which the angle is minimized. At this time, the claw member 3 is naturally positioned by the action of the spring 7 and supports both mounting members, so that the operation does not require any special steps and becomes very smooth. Despite this, the outermost rear portion 3b of the lever portion 3a makes point contact at the deepest portion 6b of the claw fitting portion 6 and supports the two mounting members in a so-called upright state (FIG. 2). The angle between the two mounting members can be supported. In addition, due to the point contact and the action of the spring 7, the claw member 3 is hardly displaced in a direction in which the claw member 3 comes off, and an erroneous operation such as folding during use is also eliminated. In this operation and effect, the spring 7 does not require a very large stress due to the angular relationship between the upper corner 6a of the claw fitting portion 6 and the lever portion 3b and the non-sliding property due to point contact. And the spring 7 can be used semi-permanently because it keeps almost its natural length. In addition, the folding operation from the use position,
Simply pressing the lever portion 3a of the claw member 3 with a finger causes the claw member 3 to be disengaged from the claw fitting portion 6 and does not support both mounting members, thereby simplifying the operation.

Here, a case where the entire furniture is foldably mounted by using the mounting bracket of the present invention will be described. FIG. 5 and FIG. 6 are explanatory perspective views when a shelf is mounted on a pillar using the mounting bracket according to the present invention. FIG. 5 shows a state in which a shelf is used, and the first mounting member 1 is fixed to the shelf plate 9 and the second mounting member 2 is fixed to the column 10 with the angle A being 90 degrees, and screwed through the screw holes 1c and 2c, respectively. I have. At this time, the mounting bracket supports the shelf board 9 with high strength by the action of the claw member 3 and can be used as a shelf sufficiently.

FIG. 6 shows a state in which the shelf is folded. When folding as shown in FIG. 6 from the use state as shown in FIG.
By pressing the lever portion 3a while holding the claw member 3, the claw member 3 is taken out from the claw fitting portion 6, and the shelf plate 9 may be rotated as it is. Such a folding operation does not require a large force and is easy. Conversely, from the folded state (see FIG. 6) to the use state (see FIG. 5)
When the shelf plate 9 is vertical, the claw member 3 is fitted into the claw fitting portion 6, and the shelf plate 9 is naturally positioned and fixed. Therefore, it is only necessary to rotate the shelf plate 9 upward. Operability is very good.

Next, a case where a part of the furniture is foldably mounted will be described. FIG. 7 is an explanatory perspective view of a case where the mounting bracket of the present invention is used when the legs are mounted on the tabletop. The leg 12 is fixed to the first mounting member 1 and the roof 11 is fixed to the second mounting member 2 with screws (not shown). Although FIG. 7 shows the folded state, the leg 12 is not folded by the action of the claw member 3 in the used state. Moreover, the operation of rotating the legs is easy, and the installation of the legs, which is an operation from the position shown in FIG. 7 to the use position, is very simple.

For convenience, the state in which the mounting surfaces of both mounting members are substantially parallel has been referred to as the folded state and the vertical state has been referred to as the use state. However, the method of use is not limited to the character face. It is also conceivable to mount the camera such that the angle A during folding and storage is vertical. Further, the role of the first and second attachment members is not limited to the above-described embodiment. For example, in FIG. 5, the first attachment member may be attached to a pillar.
Further, the shape of the claw member is not limited to the above-described embodiment, and may be a mere plate shape as long as the above-described configuration such as the contact state and the fitted state and the operational effects are exhibited. In addition, it goes without saying that the configuration, shape, and the like can be changed without departing from the spirit of the present invention.

[0015]

According to the mounting bracket of the first aspect of the present invention, the strength during use can be made extremely strong with a simple structure, and there is no malfunction such as folding during use.
In particular, since the operation from the folding position to the use position can be easily performed, a tremendous effect is produced when manufacturing and installing the folding furniture.
