Abstract

PROBLEM TO BE SOLVED: To solve a problem of a showcase for exhibition, a problem that lacks realism on account of a feeling of entrapment for an exhibit, which is caused by using an upright tetrahedron composed of a rectangular parallelepiped or a cube.SOLUTION: With a ring-shaped revolving ball bearing as a base, a housing part of an exhibit is made a cylinder, making a door part as a revolving door using a 1/2 of the cylinder, making the remaining 1/2 also a cylindrical shape, and forming a structure by integrating the back face and the side face, with a take-out port of the door designed as an opening with depth. Consequently, exhibition work can be smoothly carried out, causing no failure when the door is moved. Also, by having the upright cylindrical shape, the showcase with a revolving door has no corners of an acute angle, which brings an effect of relieving collision of a moving object. Furthermore, the showcase eliminates a feeling of entrapment for the exhibit and enables the exhibition with a sense of realism.

Description

The present invention relates to a structure of a showcase with a rotating door, which is intended to be able to safely store and display exhibits and products without sacrificing the realism of the real thing.

Traditionally, display cases that have been installed in shops, event venues, and museums have four corners that “print out” at 90 degrees, with four support pillars “metal” or an upright glass tetrahedron, structure. ,
Glass butt construction method “Silicon construction method of silicon or high-clear to the glass mouth,
We are staying in construction technology by “adhesion method of bonding glass together using UV bonding”
The adhesive part was peeled off and the glass mouth was separated, causing damage to the storage chamber. In addition, when the viewer appreciates the exhibits in the case, the corners of the four corners hindered the real sense of reality. Moreover, the doors are opened and closed when putting in and out the goods, but specific examples in which the doors are damaged and the case storage chamber is frequently damaged when moving are shown below.

Because the shape of the storage room of the showcase that stores products and exhibits is a hexahedron, which is a hexahedron consisting of left and right glass side plates, back plate, door plate, top frame plate, and bottom plate plate. In addition, because the corners of the four corners could only be made into a shape with 90-degree support pillars or a glass-to-glass butt construction method, the vertical surface 1 / There was a lot of danger of the product colliding with the side plate if the 4 doors were forced in and out, and care was not taken in storage.

In addition, when storing exhibits in a case, a glass door hinge is usually provided as a commonly used door opening and closing device. Open and close the door. The problem that arises in that case is that the door glass is attached directly to the top and bottom of the door, so the torsional load is applied to the glass of the door, and the door is displaced due to the undulation of the glass due to the rotation of the hinge. This was the cause of breaking the balance, causing the door to collide with the wall, and damaging the door or the wall. Alternatively, if the door load is applied to the pivot that is the rotating shaft and is caused by uneven torsional stress due to wear, the door crashes, the door falls, the case body around the door breaks, wind pressure The collision of the door that occurred, and the worst situation, also caused damage to the exhibits.
The glass door hinge is a “metal fitting that provides a suspension shaft on the upper and lower sides of one side of the door and rotates the support shaft”.
The pivot is a toothed shaft bracket that supports a rotating body at a part of a hinge, that is, a door and a fixed frame, and supports a door suspension at one point in the vertical direction.

The second, “Glass sliding door” for the glass door is provided, and a glass sliding door is provided on the lower side of the glass to open and close the horizontally movable movement. The problem that occurs in this case is that the derailment or fine adjustment of the moving speed does not work due to the wear of the guide rail and the door pulley and the vibration of the pulley, and the door tip of the door collides with the side surface. In addition, the door was scratched or damaged, resulting in a failure or accident.
Hakama is a member that is made of metal on the top or bottom of the glass and receives the glass load on one side. The material is made of aluminum, stainless steel, and steel, and a door is installed in the built-in part. It is a movable member.

The third, the glass door drawer "Glass drawer" on the floor of the case, a slide rail is provided, and the floor and the glass drawer provided on the side of the door surface and the upper part are pulled out to the front. By holding and holding the glass part that is fixed by inserting and opening and closing the door, the glass and fixtures are fixed according to the lever principle, and the glass drawer is broken from the twist due to compression, or at the time of display. It caused the collision damage to occur. As described above, when the conventional techniques described above are used, there is a problem in that repairs are unavoidable although there is a difference in frequency of use.

Conventionally, a cylindrical showcase has been disclosed as disclosed in Japanese Utility Model Publication No. 61-60771, but the cylindrical side surface portion is an object that holds an opening and is not completely sealed. Since there is no boundary between the display part of the case and the outside and the fully closed state is not maintained, there is a drawback that the displayed product can be easily taken out.

Japanese Patent Application Laid-Open No. 08-056787 Japanese Utility Model Publication No. 61-7355 Japanese Utility Model Publication No. 61-60771

The conventional showcase has two planes, the ceiling and floor, and a vertical plane consisting of “two sides, back, door” on the vertical surface. There was no choice but to hold a storage room consisting of a certain “ink” structure. One of the structures used when opening and closing the door is a method of moving the door radially by providing upper and lower hinges on the surface to be the door in the case of the hinged door type. Secondly, the sliding door type is a method in which a hook is put on the upper surface or lower edge of the door, a pulley is provided inside, and it is moved in parallel in the lateral direction. Thirdly, in the drawer type, a sliding rail is applied to the floor, and the door is movable in an integrated manner with the floor and the side windows at the top. There was only a door opening and closing method consisting of the above three types. For this reason, in the case of the hinged door type, the door is damaged due to the load breakage, the torsion caused by the malfunction of the hinge, and the door is caused by the vibration caused by the bending. Alternatively, the Hakama type causes damage due to a failure such as derailment due to a door wheel. Degradation due to aging, and peeling of the glass adhesive surface due to vibrations caused by collisions. In the drawer type, the glass and fixtures were fixed, and the glass drawer was damaged due to compression. The purpose is to solve these problems.

Furthermore, on the design side, when viewing the display, an obtrusive jig (door key, hinge that moves the door, hakama) jumps into the eye, and the tetrahedron “ The corners or frames that support the surface give viewers a sense of blockage of the products and exhibits, impairing the sense of reality.
The purpose is to solve these problems.
