Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a so-called lift hinge in which the pivot point is at the front end of the side end face of the door, and is used when fixing the box body and the door. The present invention relates to a hinge that can be temporarily fixed in an accurate positioning state and that can be easily attached to a box body and a door with screws in this temporarily fixed state.

(b) Conventional technology Conventional hinges have various structures.
For example, the take-out hinge of Utility Model Application Publication No. 63-165078 consists of a mounting piece for the box body and a door mounting piece, which are rotatably connected via a pin shaft. A fixing screw hole is opened, a driving script is provided protruding from the attachment piece to the door, and a retaining protrusion is provided on the circumferential surface of the driving script (not shown).

When attaching the door to the box body using this hinge, first, the attachment piece to the box body is brought into contact with the side wall of the box body, and screws are screwed into the screw holes to secure the attachment piece to the box body. After this,
Drive the leg for driving the mounting piece into the door into the mounting hole prepared in advance on the door. During this driving, the temporary fixing protrusion of the driving leg bites into the inner peripheral surface of the mounting hole, and the mounting piece is fixed to the door.

According to this hinge, the door can be attached without using screws or tools by simply driving the legs of the hinge, with one attachment piece fixed to the side wall of the box body, into the attachment hole of the door.

(c) Problems to be solved by the invention In the above-mentioned take-out hinge, after the mounting piece to the box body is fixed to the side wall of the box body with screws,
The legs of the mounting piece for the door are driven into the mounting hole of the door and fixed. However, this hinge does not have a positioning point (positioning means) when attaching the mounting piece to the box body to the side wall of the box body with screws. For amateurs such as consumers, it is not easy to attach and fix the hinges to match the end faces of the box body and the door. If the fixing positions (screw fixing points) between the box body and the attachment piece to the box body are incorrect, the corresponding positions of the legs and the mounting holes will shift. In other words, it becomes impossible to drive the legs in, and the screw fixing work must be redone. Moreover, in this screw fixing work, the worker must hold the hinge with one hand and screw in the screw with the other hand, which is extremely difficult for amateurs such as consumers. It is also possible to first drive the legs into the mounting holes and fix them to the door, and then fix the mounting piece to the box body with screws to the side wall of the box. In this case, the risk of incorrect positioning points (screw fastening points) is almost eliminated, but at the same time, when gripping not only the hinge but also the door that is integrated with the hinge,
There were disadvantages such as having to perform screw fixing work, which was extremely difficult work.

This invention solves the above-mentioned problems by temporarily fixing the box body and the door in the proper position via the hinge, and in this temporarily fixed state, it is possible to perform screw fixing work, which is accurate and easy to install. The purpose is to provide a hinge that is easy to use.

(d) Means and action for solving the problem In order to achieve this purpose, the hinge of this invention has the following configuration.

The hinge is a hinge formed by rotatably connecting a mounting piece to the box body and a mounting piece to the door via a pin shaft, the mounting piece to the box body,
The mounting pieces for the door are provided with protruding pins for positioning and temporary fixing that correspond to the temporary fixing holes provided in the box body and the door, respectively, and the mounting pieces for the box body and the door are , each is characterized by the provision of fixing screw holes for fixing the temporarily fixed state.

In a hinge with such a configuration, holes for temporary fixing are provided in advance at appropriate positions on the box body and the door, and holes for temporary fixing are provided on the mounting piece to the box body and the mounting piece to the door, respectively. A protruding pin for positioning and temporary fixing is provided corresponding to the hole. Therefore, for the temporary fixing holes in the box body and door,
Proper positioning of the door and box body can be achieved simply by fitting the protruding pins on the hinge (both mounting pieces). Moreover, by fitting the protruding pin into the temporary fixing hole, this proper installation state (temporary fixing state) can be achieved.
is retained. Therefore, when performing complete fixing work (screw fastening work), there is no need to hold the hinge (both mounting pieces) as well as the door and the box body. Using both hands in a free state, the operator inserts screws into the fixing screw holes of both mounting pieces and screws them into the box body and door in sequence to completely fix (fasten) them. In other words, the worker can use both hands freely and concentrate only on fixing the screws, making the installation work easier. Further, since the box body and the door are fixed with screws while they are temporarily fixed in the proper state, there is no risk of the door being fixed in a misaligned manner with respect to the box body.

(E) Embodiment FIG. 1 is a perspective view showing a specific embodiment of the hinge according to this invention.

As is well known, the hinge consists of a mounting piece 1 for attaching to the door, a mounting piece 2 for attaching to the box body, and a pin shaft 3 that rotatably supports both the mounting pieces 1 and 2.

In the embodiment, the door attachment piece 1 has an "L"-shaped cross section, consisting of a vertical part 12 whose tip is rotatably wound around the pin shaft 3, and a horizontal door attachment part 11. It is formed in This flat mounting part 11 is
The proximal end side (vertical part 12 side) is set to be the same width as the vertical part 12, and the distal end side is set to be wide (width length approximately equal to the length of the pin shaft 3) via the stepped part 11a.

The mounting piece 2 to the box body has a flat mounting part 21 having a width approximately equal to the length of the pin shaft 3, a vertical part 22 continuous to both ends of the mounting part 21, and a vertical part 22 that is continuous with both ends of the mounting part 21. The horizontal portion 23 has a horizontally bent tip and is rotatably wound around both ends of the pin shaft 3. In other words,
The vertical portion 22 and the horizontal portion 23 are formed in an “L” shape in cross section, and the vertical portion 22 is located at both ends of the mounting portion 21.
2. The space between the horizontal parts 23 is cut out by a width corresponding to the width of the vertical part 12 of the mounting piece 1 to the door, and is set in an open state. Therefore, the vertical part 1 of the door mounting piece 1
2 and the narrow part (base end side) of the mounting part 11 is this notch part (between the horizontal parts 23 and between the vertical parts 22)
When inserted, the mounting portion 11 and the mounting portion 21 are set so as to be in contact with each other in an “L”-shaped cross section, that is, in a right-angled shape.

The feature of this invention is that, as shown in Fig. 2, temporary fixing holes a and b are provided in the box body A and the door B at appropriate positions in advance, respectively, so that the mounting piece 2 to the box body and the door can be easily attached. Piece 1 is provided with protruding pins 14 and 24 for positioning and temporary fixing corresponding to temporary fixing holes a and b, respectively, and fixing screw holes 11
c and 21c are provided.

In other words, as shown in Figure 1, the attachment piece 1 to the door
, protruding pins 14 for positioning and temporary fixing that stand up at right angles are provided on both in-plane ends of the mounting surface 11b of the mounting portion 11, and the in-plane center of the mounting portion 11 (between both protruding pins 14, 14) An elongated fixing screw hole 11c extending in the length direction is opened in the opening. In addition, the mounting piece 2 to the box body has a mounting portion 21.
Protruding pins 24 for positioning and temporary fixing that stand up at right angles on both in-plane ends of the mounting surface 21b are provided,
In-plane center of mounting portion 11 (both protruding pins 24, 24
A circular fixing screw hole 21c is opened in the space between the two.

Hinge T with such a configuration is used for knock-down products such as record racks and color boxes (the box body and door are separate, sold separately, the hinge is an accessory component, and the purchaser can purchase the unit product). (products that can be assembled at home).

To attach (assemble), for example, a glass plate door B to the box body A using this hinge T, as shown in FIG. The corresponding protruding pins 14 and 24 of both mounting pieces (the mounting piece to the door and the mounting piece to the box body) 1 and 2 are fitted, respectively. For these temporary fixing holes a and b, each protruding pin 1
By matching (fitting) 4 and 24, the glass plate door B and the box body A can be properly positioned. However, the protruding pin 1 for the temporary fixing holes a and b
4 and 24 are fitted, this proper attachment state (temporary fixation state) is maintained. Therefore, when performing the subsequent complete fixing work (screw fastening work), there is no need to hold the hinge (both mounting pieces 1, 2) T as well as the door B and the box body A. The worker uses both hands in a free state to attach both mounting pieces 1,
Insert screws (not shown) into the fixing screw holes 11c and 21c of No.2. When door B is a glass plate, screws (screw holes 11c, 21
By preparing a screw hole corresponding to c), the box body A and door B can be screwed together, and if door B is made of wood, screws can be inserted directly into the wood door to connect box body A and door B via hinge T. Completely fixed (fastened with screws). In other words, the operator can use both hands freely and concentrate only on screwing, making the installation work easier. In addition, since the box body A and the door B are fixed with screws while temporarily fixed in the proper position, there is no possibility that the door B will be fixed in a misaligned manner with respect to the box body A.

Thus, the installation of the box body A and the door B using this hinge T is carried out in two stages: a temporary fixing stage and a fixing stage.
Proper positioning and proper position maintenance can be achieved,
At the fixation stage, proper fixation can be achieved with extremely easy work. In addition, in the example, since the fixing screw hole 11c provided in the attachment part 11 of the attachment piece 1 to the door B is set as a long hole, the positioning for attachment to the door B is permissible in the length direction of the attachment piece 1. This allows for greater width and allows for dimensional errors in the product. Therefore, door B for box body A
The accuracy of the installation can be further ensured.

(f) Effects of the invention In this invention, as described above, the box body and door can be fixed by inserting the positioning and temporary fixing protruding pin provided on the mounting piece into the temporary fixing hole provided in the box body and door. It can be positioned in an appropriate state, and the temporarily fixed state at this appropriate position is maintained. Therefore, when attaching the door to the box body, there is no chance of incorrect fixing (fastening) points, and when completely fixing the door (fastening with screws), it is necessary to hold the hinge and door with one hand as in the past. There is no need to do so, both hands can be used freely, and the work can be concentrated only on fixing screws, making the installation work easier, and has excellent effects that achieve the purpose of the invention.
