The coupler 24 is connected to the rotating portion 22 in order to prevent it from coming off.
It is screwed onto the top and is locked in place. Similar to the cylinder unit 10, a steel ball 16b is loosely inserted into the rotating portion 22.

The ball 16a, the piston 12, the ball 16
b and rods 30a and 30b, which will be described later, constitute a pressing means.

A first arm 26a has a through hole 28a bored in its central shaft portion, and its upper end in the drawing is screwed onto the cylinder unit 10, and the through hole 28a communicates with the cylinder 14.

A rod 30a is made of, for example, a metallic round bar having sufficient rigidity and elasticity, and is connected to the through hole 2.
8a so as to be movable in the length direction.
The cylinder side end of the rod 30a reaches into the cylinder 14, and the other end reaches a recess 36a provided in the end surface of the pressing body 34a of the first ball joint 32a attached to the tip of the first arm 26a. ing. The pressing body 34a is first pressed against the ball portion 38a.
It is arranged so that it can slide inside the ball joint 32a.

The lower end of the first ball joint 32a is screwed onto the base 11. The base 11 may be fixed to the exhibition place using suitable fixing means such as bolts, or
In the case of fixing on the floor etc., there is no need for fixing means as long as there is sufficient mass.

26b is a second arm, a through hole 28b is bored in the central shaft part, and the lower end in the drawing is the rotating part 22.
The through hole 28b communicates with a space in which the ball 16b of the rotating portion 22 is installed.

A rod 30b is made of a metallic round bar having sufficient rigidity and elasticity like the rod 30a, and is inserted into the through hole 28b so as to be movable in the length direction. The end of the rod 30b on the rotating part side reaches inside the rotating part 22, and the other end is connected to the second arm 2.

The mounting section 13 may have an appropriate shape in consideration of the shape of the exhibit to be mounted.

The display device according to the present invention is constructed as described above. Next, the operation and usage will be explained.

In order to fix the mounting portion 13 at a predetermined angle and position, first and second ball joints 32a, 32b, a first
Then, the second arms 26a, 26b and the rotating portion 22 are set at appropriate angles, and the handle 18 is turned in the tightening direction. Then, the threaded portion 20 enters the cylinder unit 10 from an oblique direction, and the tip of the threaded portion 20 comes into contact with the ball 16a. Furthermore, the handle 18
When tightened, the tip of the threaded portion 20 pushes the ball 16a to the lower left in the drawing. When the ball 16a moves, the ball 16a touches the rod 30a and the piston 12.
The force acting on the ball 16a from the handle 18 is divided into a force pushing the rod 30a downward and a force pushing the piston 12 leftward. At this time, the force pushing the rod 30a pushes the rod 30a downward.

When the rod 30a is pushed, the lower end of the rod 30a presses the pressing body 34a of the first ball joint 32b downward, and the first pressing body 34a presses the ball portion 38a to fix the first ball joint 32a. . On the other hand, the force acting on the piston 12 pushes the piston 12 to the left.
The pushed piston 12 hits the ball 16b on the left end surface.
Push to the left. When the ball 16b is pushed, it comes into contact with the rod 30b and the inner wall 40 of the rotating portion 22. When the ball 16b is further pushed, the force acting on the ball 16b is divided into a force pushing the inner wall 40 formed on the slope and a force pushing the rod 30b upward in the drawing. The force pushing the inner wall 40 of the rotating part 22 directly presses the ball 16b against the inner wall 40, so the coupler 24 screwed onto the rotating part 22 and the sliding surface of the cylinder unit 10 come into contact and rotate due to frictional force. The movement of the moving part 22 is prevented and the position of the rotating part 22 relative to the cylinder unit 10 is fixed. On the other hand, the force acting on rod 30b causes rod 30b to move upward. When the rod 30b is pressed, the rod 30b
The upper end pushes the pressing body 34b of the second ball joint 32b upward, and the pressing body 34b presses the ball portion 38b to fix the second ball joint 32b.

When the second ball joint 32b is fixed, the mounting portion 13 screwed onto the upper end of the second ball joint 32b is also fixed at a predetermined angle and position.

Therefore, it is possible to place and display an exhibition item, for example, shoes 15, on the upper surface of the placing portion 13.

When displaying, the base 11 is fixed in a predetermined position,
Or you can put it up and display it.

When loosening the fixation of movable parts, use the handle 18.
When turned in the loosening direction, the pressing force of the handle is released, the balls 16a, 16b and the piston 12 return to their original positions, and the mechanically compressed rod 30 is released.
Since elements a, 30b, etc. also return to their previous states due to elasticity, the fixation of the first and second ball joints 32a, 32b and the rotating portion 22 is released, allowing reuse and adjustment.

Next, another embodiment will be described with reference to FIG.

In the embodiment shown in FIG. 1, the balls 16a, 16b, the piston 12, and the rods 30a, 30b were used as the pressing means, but in this embodiment, an example in which hydraulic pressure, for example oil pressure, is used as the pressing means will be described. .

Set the base 111 at a predetermined display position, and
The first arm 110 and the second arm are moved by moving the ball joint 114, the second ball joint 122, and the rotating portion 108 rotatably fitted onto the cylinder unit 100.
The position and angle of the mounting portion 113 are determined by arbitrarily setting the position of the second arm 118 and moving the second ball joint 122 attached to the tip of the second arm 118. Once the position and angle of the placement part 113 are determined, handle 1
By tightening 06, the plunger 104 applies pressure to the oil that is the pressing means in the cylinder 102 and chambers 112, 120, and the first and second ball joints 114, 122, the first arm 110, and the second arm 118 and the cylinder unit 1 at the contact portion 117.
00 is fixed in position.

When the movable part is fixed, the position and angle of the mounting section 113 are also fixed, so that the shoes 115, which are exhibit items, can be placed on the upper surface of the mounting section 113 and displayed.

Furthermore, when loosening the display device, rotating the handle 106 in the opposite direction to tightening will lower the oil pressure and cause the first and second ball joints 114, 12
