Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door hinge structure, and more particularly to a glass door hinge structure for a showcase.

[0002]

[Prior art]

 Refrigeration showcases that are often found in markets, convenience stores, and food stores such as liquor stores require excellent heat insulation to maintain their refrigeration performance, and are intended to display food products. The showcase doors are made of large-area glass panes so that they are easy to see and look good.

[0003] Such doors are supported at their upper and lower corners on the door frame by hinge members and are pivotally fixed so that they can be opened and closed. This causes the door to tilt and drop.

Therefore, in order to adjust such a shoulder drop, a long hole is provided in the door frame body, the pin portion of the hinge member is inserted into this long hole, and the shoulder is lowered by sliding in the longitudinal direction of the long hole. It is proposed to adjust.

[0005]

[Problems to be solved by the device]

 However, the insertion part of the pin inserted in the above-mentioned long hole has a small cross-sectional area with respect to the size of the long hole, so that it can be easily removed from the long hole when an external impact force is applied to the door. Since it slips off and the danger of falling off the door is apologized, it has the drawback of causing safety concerns.

Therefore, if the pin is firmly fixed to the specific position of the long hole, the anxiety of the door coming off is eliminated, but the dimensional error between the door and the door frame is mitigated. It becomes difficult to slide the long hole in the longitudinal direction, which was effective for the above, and it becomes impossible to finely adjust the tilt of the door.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a new hinge structure for a door that has not been heretofore used.

[0008]

[Means for Solving the Problems]

 The present invention has been made to solve the above-described problems, and has an upper hinge member that supports an upper corner of a door and a lower hinge member that supports a lower corner of the door, so that the door can be opened and closed. A hinge structure for a door that is pivotally locked to a door frame body, wherein at least the lower hinge member is inserted into an elongated hole provided at a lower corner of the door frame body. The pin includes a pin, a fixing member that fixes the position of the pin to the door frame, and a connecting member that is located between the pin and the fixing member and that freely determines the distance between the pin and the fixing member. The first insertion part is slidable in the longitudinal direction of the slot according to the determined distance between the pin and the fixing member, and the second insertion part above the pin is inserted into the door. Providing a characteristic door hinge structure It is intended to.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged view of an essential part showing an example of a hinge structure of the present invention. The hinge member 3 is composed of a fixing member 4, a connecting member 5 and a pin 6, and the door 1 is provided with a hinge hole 11 for receiving the second inserting portion 26 of the pin 6, and this second inserting portion is provided. 26 is pivotally supported. The pin 6 has a second insertion portion 26 and an elongated first insertion portion 16 that is inserted into the long hole 12 of the door frame body 2. The first insertion portion 16 has a long hole 12 It is slidable in the longitudinal direction. A fixing member 4 is fixed to the door frame body 2 by, for example, a screw so as to be aligned with the long hole in the longitudinal direction, and the pin 6 and the fixing member 4 are fixed by a connecting member 5 that freely determines the distance between them. The pin 6 is fixed to the door frame 2 at a fixed interval.

At this time, the pin 6 slides in the longitudinal direction of the long hole 12 to a predetermined position while adjusting the distance between the pin 6 and the fixing member 4 while being inserted into the long hole 12 by the connecting member 5. It is positioned and fixed to the door frame 2.

FIG. 2 is a conceptual view of the lower surface viewed from the direction A of FIG. 1, and FIG. 3 is a conceptual view of the upper surface viewed from the direction B of FIG.

The first insertion portion 16 of the pin 6 is inserted into the long hole 12 provided in the door frame body 2 so as to prevent the pin 6, and thus the door, from coming off from the door frame body 2. The length b in the longitudinal direction of the first insertion portion 16 is preferably about 10 to 20 mm shorter than the length a in the longitudinal direction of the elongated holes 12.

The connecting member 5 connects and fixes the fixing member 4 fixed to the door frame body 2 with a screw or the like to the pin 6, and the pin 6 is fixed via the fixing member 4 fixed to the door frame body 2. Is used to firmly fix the to the door frame body 2. Further, the connecting member 5 can freely determine the distance between the fixing member 4 and the pin 6, and by sliding the position of the pin 6 in the longitudinal direction of the slot 12, the door frame 2 and the door are separated from each other. It is possible to absorb the large force applied to the hinge member by adjusting the dimensional error or the shoulder drop of the door due to long-term use.

The insertion height of the first insertion portion 16 of the pin 6 is 5 mm or more so that the pin 6 will not be disengaged from the elongated hole 12 against an impact received when the door is roughly opened and closed. Preferably.

[0016]

[Effect of device]

 According to the present invention, construction of the position of the hinge member that pivotally locks the door to the door frame body due to the dimensional error between the door and the door frame body and the shoulder drop of the door caused by long-term use is performed. It can be adjusted by moving the door frame in the longitudinal direction at the time of or after construction, and it is possible to prevent problems of opening and closing the door due to the shoulder of the door being lowered.

Further, according to the present invention, since the position of the hinge member with respect to the door frame can be easily moved by adjusting the connecting member during or after the construction, the door is pivoted on the door frame. The stopping work can be performed easily and the difficulty of construction can be eliminated.
