Abstract
Description
Technical Field
[0001] The present invention relates to a hinge structure for a door of a steel storage or the like.
Background Art
[0002] In recent years, the usage modes of steel storage have diversified. For example, in offices and the like, storage cabinets with doors (personal lockers) assigned to each employee are used.
[0003] By the way, in a conventional steel storage cabinet with a door, a hinge mechanism for swingably supporting the door on the main body attaches a hinge member (hinge leaf) to the main body and the door of the storage cabinet by screws or welding (see, for example, Patent Document 1). In the case of this hinge mechanism for the door, since it is necessary to attach the hinge member to the main body and the door of the storage cabinet by screws or welding, there is a problem that the attachment work of the hinge member and the attachment work of attaching the door to the main body of the storage cabinet are troublesome. In particular, in the case of a personal locker or the like in which many doors are attached to the main body of the storage cabinet, this problem is remarkable.

Problems to be Solved by the Invention
[0005] In view of the problems of the hinge structure of the door of the above-mentioned steel storage or the like, an object of the present invention is to provide a hinge structure for a door that can easily perform the attachment work of the hinge member and the attachment work of the door.
Means for Solving the Problems
[0006] To achieve the above object, the hinge structure of the door of the present invention comprises a first hinge member having a pin insertion hole attached to the main body side, and a second hinge member having a pin attached to the door side. The pin of the second hinge member is inserted into the pin insertion hole of the first hinge member, so that the door is swingably supported on the main body. The second hinge member comprises a main body portion fitted to a sheet metal door, a pin holder movably attached to the main body portion, and a pin attached to the pin holder.
[0007] In this case, the pin holder of the second hinge member is provided so as to be selectively positioned at a temporary fixing position and a main fixing position with respect to the main body portion. At the temporary fixing position, the tip of the pin is inserted into the pin insertion hole of the first hinge member, and at the main fixing position, the pin can be inserted into the pin insertion hole of the first hinge member.
Advantages of the Invention
[0008] According to the hinge structure of the door of the present invention, the attachment work of the hinge member and the attachment work of the door can be easily performed.

Embodiments for Carrying out the Invention
[0010] Hereinafter, embodiments of the hinge structure of the door of the present invention will be described with reference to the drawings.
[0011] Figs. 1 to 6 show an example in which the hinge structure of the door of the present invention is applied to a steel storage cabinet. This hinge structure of the door comprises a first hinge member 1 having a pin insertion hole 11 attached to the main body B side of a steel storage cabinet, and a second hinge member 2 having a pin 21 attached to the door D side. The pin 21 of the second hinge member 2 is inserted into the pin insertion hole 11 of the first hinge member 1 so that the door D can be swingably supported by the main body B. The second hinge member 2 includes a main body portion 22 fitted to a sheet metal door D, a pin holder 23 movably attached to the main body portion 22, and a pin 21 attached to the pin holder 23.
[0012] Here, as shown in the process explanatory diagram of attaching the second hinge member 2 to the door D of the steel storage cabinet in Fig. 1, the second hinge member 2 is formed with a fitting recess 22b into which a fitting piece 22a formed in the frame portion of the sheet metal door D is fitted and a fitting claw 22d that fits into a fitting hole 22c formed in the same frame portion so that the second hinge member 2 can be fixed to the sheet metal door D by fitting the main body portion 22 thereto. Thereby, the second hinge member 2 with the pin holder 23 to which the pin 21 is attached and positioned at the temporary fixing position on the main body portion 22 can be fitted and fixed to the sheet metal door D simply by sliding it without using screws, welding, etc., and the attachment work of the second hinge member 2 can be easily performed.
[0013] The pin holder 23 of the second hinge member 2 is provided so as to be selectively positioned at a temporary fixing position and a main fixing position with respect to the main body portion 22. Then, as shown in the process explanatory diagram of attaching a door to the main body of the steel storage shown in FIG. 2, at the temporary fixing position, the tip portion 21a of the pin 21 is inserted into the pin insertion hole 11 of the first hinge member 1, and at the main fixing position, the pin 21 is inserted through the pin insertion hole 11 of the first hinge member 1.
[0014] More specifically, when the pin holder 23 of the second hinge member 2 is positioned at the temporary fixing position, the tip portion 21a of the pin 21 having a frustum - shaped tip is made to protrude about 1 mm into the insertion groove 22e formed in the main body portion 22 of the second hinge member 2 into which the first hinge member 1 is inserted (FIGS. 2(a) and (a1)). In this state, when the first hinge member 1 is inserted into the insertion groove 22e, the first hinge member 1 abuts against the tip portion 21a of the pin 21 and the pin 21 is pushed down. This pushing - down of the pin 21 is absorbed by the elastic deformation of the locking portion between the main body portion 22 of the second hinge member 2 made of synthetic resin such as polyacetal resin and the pin holder 23 (FIG. 2(a2)). And when the position of the pin insertion hole 11 of the first hinge member 1 and the position of the pin 21 coincide, the pushed - down pin 21 is elastically restored by the locking portion between the main body portion 22 of the synthetic resin - made second hinge member 2 and the pin holder 23 which has been elastically deformed, so that the tip portion 21a of the pin 21 is inserted into the pin insertion hole 11 of the first hinge member 1, and the door D can be temporarily fixed (temporarily supported) (FIG. 2(a3)). Next, by pushing in the pin holder 23 of the second hinge member 2 and positioning the pin holder 23 from the temporary fixing position to the main fixing position, the pin 21 is inserted through the pin insertion hole 11 of the first hinge member 1, and the door D is fixedly supported (FIG. 2(b)). When the pin holder 23 is positioned at the main fixed position, the tip 21a of the pin 21 is inserted into the hole 22f formed in the main body 22 of the second hinge member 2, and the pin 21 can be stably pivotally supported in a two - supported manner on the main body 22 of the first hinge member 1 with the first hinge member 1 sandwiched therebetween. Thereby, the attachment operation of attaching the door D to the main body B of the steel storage can be easily performed without using screws or tools.
[0015] The attachment of the first hinge member 1 to the main body B of the steel storage is performed by inserting the base 12b of the first hinge member 1 into the insertion groove 12a formed in the main body B and spot - welding 13 as shown in FIG. 6, but other fixing means using screws or the like can also be used.
[0016] As described above, the hinge structure of the door of the present invention has been described based on its embodiments. However, the present invention is not limited to the configurations described in the above embodiments, and its configuration can be appropriately changed without departing from the gist thereof.
Industrial Applicability
[0017] The hinge structure of the door of the present invention can easily perform the attachment operation of the hinge member and the attachment operation of the door. Therefore, it can be suitably used for a storage with a door body (personal locker) assigned to each employee used in an office or the like, and can also be widely used for steel storages and the like.
