Description

[Detailed description of the invention] <Industrial application field> This invention is used for a frame structure connected with X-shaped frame rods, and the X-shaped frame rods function as a connecting tool and can be used to hold exhibits such as paintings. The present invention relates to an exhibit fixture that has a function of mounting and supporting.

<Prior Art> Conventionally, four X-shaped frame rods are connected in a circumferential direction via a connecting tool, and the X-shaped frame rods are sequentially connected to one or more surfaces of a four-sided frame body via a connecting tool. In a frame structure in which a plurality of four-sided frames are connected to form a plurality of four-sided frames, when exhibits such as paintings are mounted and displayed, mounting holes are opened on the surface side of each connector of the four-sided frames and in the four corners of the exhibit, respectively. Both mounting holes are used to secure exhibits with screws, etc., and display them on a hanging rack.

However, because they use fasteners with small heads such as screws, they do not hold the exhibits sufficiently.
Furthermore, the screws and other fasteners are exposed on the front of the exhibit, which is unfavorable in terms of appearance.

<Problems to be solved by the invention> The problems to be solved by the invention are to fix exhibits so that they do not move in multiple directions on the display surface, and to securely hold them in a wide area. It is in.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to form a four-sided frame by connecting four X-shaped frame rods in a circumferential direction via connectors. In a frame structure in which a plurality of four-sided frames are formed by sequentially connecting the X-shaped frame rods to one or more surfaces of the body via connectors, a screw hole is opened at the center of the front surface of the connector. It also consists of a mounting support with guide pins protruding from the four corners on the same side, and a fastener that is removably attached to the mounting support. A tightening plate with pin insertion holes drilled in four corners facing the guide pin, and an operation knob at one end of a screw portion that screws into the screw hole, and the screw portion is rotated into the support hole of the tightening plate. It is characterized by being composed of a freely supported operating section.

<Operation> Each corner of the exhibit is inserted into each of the guide pins protruding from the mounting support through the mounting holes drilled there, and then the guide pins are inserted from the surface side of the exhibit. By inserting the fastener into the pin through the pin insertion hole and rotating the operating section in the tightening direction, the threaded part is screwed into the threaded part of the mounting support, and the exhibit is mounted and supported. Press between the tool and the clamping plate.

<Example> An embodiment of the present invention will be described based on the drawings.

B is a frame structure, with two frame rods 10 of equal length,
One or more faces of a four-sided frame B' formed by connecting X-shaped frame rods b ₁ rotatably supported at the intersections of 10 to 10 points in a circumferential direction via connectors b ₂ at each end thereof. A plurality of four-sided frames B' are successively formed by sequentially connecting the X-shaped frame rods _b1 to the surfaces via connectors _b2 .

In this frame structure B, the connecting tool b ₂ is arranged with the open side plane facing the frame rod 10 mounting side facing the front side, and the X-shaped frame rod b ₁ is rotated appropriately and placed at a desired four-way position. Rectangular display surfaces _b3 are formed continuously and adjacently.

The exhibit mounting fixture A of the present invention is composed of a mounting support 1 formed from the above-mentioned connector _b2 , and a fastening tool 2 that is detachably attached to the mounting support 1.

The connector b ₂ has a rectangular planar shape and has a structure in which a support piece 101 is protruded in a cross shape from the mounting surface, and the end of each frame rod 10 is attached to the support piece 101 with a pin or the like so that it can rotate freely. It is now connected to.

The mounting support 1 has a screw hole 1a opened in the center of the front surface of the connector _b2 , and cylindrical guide pins 1b protruding from the four corners of the same surface.

The tightening tool 2 includes a tightening plate 2a, an operation part 2b rotatably screwed onto the tightening plate 2a, and both 2a.
The intermediate ring 2c is interposed between a and 2b and has a substantially donut shape and has an insertion hole 204 in the center.

The clamping plate 2a is formed in the same shape as the flat mounting support 1, has a support hole 205 in the center, and has guide pins 1b of the mounting support 1 in the four corners.
A pin insertion hole 201 is drilled through which the pin is inserted.

The operating portion 2b is connected to the screw hole 1a of the mounting support 1.
A disc-shaped operating knob 203 is fixed to one end of a screw portion 202 that is screwed into the intermediate ring 2c.
is interposed between the clamping plate 2a and the intermediate ring 2c.
insertion hole 204 and support hole 205 of the tightening plate 2a
Then, insert the threaded part 202 to the position of the operating knob 03, and lock an E-ring or the like to the threaded part 202 on the side of the tightening plate 2a opposite to the operating knob 203 in close proximity to the tightening plate 2a. The ring 3 is fitted and fixed.

By installing this locking ring 3, the operation part 2
b is rotatably supported by the clamping plate 2a via the support hole 205.

Further, the intermediate ring 2c interposed between the operating knob 203 and the tightening plate 2a is connected to the operating knob 203 and the tightening plate 2a.
This makes it easier to hold the operation knob 203 by maintaining an appropriate distance from the handle 20a, and also supports the operation knob 203 so that it can be easily rotated.

The exhibit mounting device A constructed in this manner is placed at the position of the connector _b2 of the frame structure B described above.

Next, a process of attaching an exhibit C having attachment holes _c1 at the four corners to the exhibit attaching devices A located on all sides of the exhibit surface _b3 configured in the frame structure B will be described.

First, rotate the operation knob 203 of the fastener 2 in the loosening direction to loosen the threaded connection between the screw portion 202 and the threaded hole 1a of the mounting support 1, remove the fastener 2 from the mounting support 1, and remove the exhibit. C is inserted through the guide pin 1b of each mounting support ₁ through the mounting hole c1 and fixed.

Then, the fastener 2 is inserted into the guide pin 1b through the pin insertion hole 201 and brought into contact with the corner surface of the exhibit C. As a result, the screw portion 20 of the operating portion 2b
2 ends come into contact with the end of the screw hole 1a of the mounting support 1.

In this state, the operation knob 203 is rotated in the tightening direction to screw and tighten the screw portion 202 of the operation portion 2b into the screw hole 1a of the mounting support 1.

In this way, the exhibit C is held under pressure between the mounting support ₁ and the clamping plate 2a of the clamping tool 2, with the four corners supported by the guide pins 1b through the mounting holes c1. Ru.

Note that after this, the exhibit C can be attached to the exhibit attachment device A in the same manner as described above for other exhibits _b3 as well, if necessary.

Furthermore, in this embodiment, as the frame structure B, a structure is used in which the size of the exhibition surface b ₃ can be changed freely by the X-shaped frame rod b ₁ in a rotatable manner.
Of course, it is also applicable to a fixed structure in which _b3 is set to a predetermined size.

<Effects of the invention> As described above, the present invention fixes the exhibit to the guide pin of the mounting support, and also inserts the fastener into the guide pin through the pin insertion hole so as to touch the surface of the exhibit. Since the screw part is screwed into the screw hole of the mounting support by rotating the operating part in the tightening direction, the exhibit is held tightly between the mounting support and the tightening plate. Ru.

Therefore, unlike the conventional case where the exhibit is held only with fasteners such as screws, the exhibit can be held securely.

In addition, while the clamping plate is in contact with the exhibit, the operating panel placed on the outside of the clamping plate is rotated to clamp the exhibit, so unlike conventional fasteners, the exhibit can be rotated. Does not leave any scars.

Furthermore, since the fasteners such as screws are not directly exposed on the surface of the exhibit as in the past, the aesthetic appearance can be improved by forming the fasteners into a desired design.

Thus, the intended purpose can be achieved.
