Description

[Detailed description of the invention] [Industrial field] The present invention is a horizontal hinge used for rotatably attaching a single- or double-opening door, especially a door made of glass plate, to a glass show case, and its installation. Concerning the structure, it can be used in a wide range of fields, such as cases where at least the entire part other than the base is made of a glass plate, cases made of a hard material similar to glass that cannot be drilled, or cases using transparent synthetic resin plates, such as various types of audio equipment. The present invention aims to provide a mounting structure that can be reliably adopted for storage cabinets for utensils, furniture, display cases, and the like.

[Conventional technology]

Conventionally, when attaching a glass door for opening and closing so that it can be rotated, if the surroundings of the side walls, ceiling, base, etc. are made of wood, etc., and it is possible to make holes, for example, as disclosed in Japanese Patent Publication No. 60-6529, the cabinet a first fixture attached to a side edge of the opening;
A second fixture is rotatably connected to this and has a holding part with a U-shaped cross section, and a decorative plate has a slit that is fitted into the side edge of the glass door that covers the opening of the cabinet. , there are known glass door mounting devices that do not require through-holes in the glass door, and when the surroundings such as side walls and ceilings are made of glass plates, it is difficult to drill holes without damaging the aesthetics, for example, in practice. As disclosed in Japanese Patent Publication No. 59-129089, a sealed door has a transparent plate attached to the frame, one side end is supported by a rotating shaft, and a handle is attached to the other side end. A show case equipped with a V-shaped engagement part biased with elastic force, an engagement lever attached to the handle part at the free end, and an engagement receiving part that engages with the V-shaped engagement part when the door is closed. There is a known device in which a device is provided in the frame of the main body.

[Problems to be solved by the invention] The above-mentioned glass door mounting device disclosed in Japanese Utility Model Publication No. 60-6529 is difficult to apply to items where drilling is difficult, such as a glass case made entirely of glass. However, even if it were adopted, depending on the method of supporting the shaft of the opening/closing door, it would be necessary to cut out or drill holes in the glass plate, reducing its strength. In the case door opening/closing device disclosed in the publication, it is necessary to engage the frame body with the glass plate of the door, side wall, ceiling, etc.
All of these require the use of a complicated frame, which increases the number of parts and increases costs.Furthermore, visibility becomes poor, and the mounting part protrudes outward from the glass plate surface, making it difficult to see through the glass. This is undesirable as it spoils the beauty of the glass case.

[Means to solve the problem]

The present invention was developed in view of the drawbacks of the conventional glass case, and does not require through holes or cutouts in the glass plate.
This is a mounting structure for an opening/closing door that is constructed by combining a support to be bonded, an adjusting member of a unique shape, and a movable and fixed connector to be fitted in a unique manner.

That is, supports are provided respectively adhered to the upper and lower regions of the inner surface of one side end of the door and the upper and lower regions of the inner surface of the side wall glass plate relative to the end, and a guide groove having a substantially rectangular planar shape having a long through hole and a circular through hole is provided. The tip of the arm extending from the side of the fixed connector main body, which is provided on one side with A hinge member supported by a rotation shaft is formed, and an adjustment member having a substantially concave cross section with an elongated hole in the center is assembled into the guide groove of the fixed connector having an elongated hole and a circular hole. Fit them together and temporarily lock them with screws, so that the guide groove of the adjustment member is connected to the key-shaped protrusion of the support on the side wall glass plate side, and the guide groove of the movable connector is connected to the key-shaped protrusion of the support on the door side. Each convex portion is temporarily locked with a screw, and after the door is positioned, each screw is further permanently locked, so that the door can be opened and closed by rotating freely around a rotation axis. This provides a mounting structure for the opening/closing door of a glass show case.

Here, the material of the supports, fixed and movable connectors, adjustment members, etc. may be made of metal, wear-resistant hard synthetic resin, etc., and the material of the base may be made of wood, glass plate, metal, etc. It's good.

In addition, a suction tool having adsorption force and spring force that engages with a metal fitting adhered to the upper corner end of the inner surface of the side end to which the handle of the opening/closing door is attached and a corresponding support adhered to the ceiling glass plate; It is designed so that the opening/closing door can be locked.

[Effect]

Due to the above-mentioned structure, the present invention does not require any drilling process on the glass plate of each part, and therefore can prevent a decrease in its strength or damage due to breakage, and has an adhesive with strong adhesive strength. It can be fixed in a short time using a compound, increasing mass production, simplifying the shape and structure of the hinge itself, and reducing the number of parts.In addition to the conventional adjustment in the vertical and horizontal directions, the door can be mounted in the front, rear, left and right directions. In addition to making it possible to adjust the rotational axes of the upper and lower hinges, it is easy to install without the need for the usual care, reduces assembly man-hours, and has an extremely superior appearance. In addition to its inherent transparency, it also has a number of features such as the smallest metal fittings, so there are no obstructions, and the contents can be observed more clearly.

Embodiments of the present invention will be described below based on the drawings shown in FIGS. 1 to 3.
