Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a hinge used for an opening / closing part that is used only for a short period of time, and relates to a hinge used for, for example, a casket opening / closing window.

[0002]

[Prior art]

 Conventionally, hinges made of thin brass plates are often used for the opening / closing windows of caskets. Such a hinge is relatively expensive and is not preferable because metal pieces remain when the casket is incinerated. Even if the left and right plate-shaped mounting pieces are made of synthetic resin, the assembly process of both is complicated and cost reduction cannot be expected so much, and since the metal rod is used in the shaft part, after incineration There is a problem that metal lumps remain.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention reduces the manufacturing cost by connecting the left and right mounting pieces, which are integrally molded of synthetic resin materials, with one-touch at the rotating shaft portion, and eliminates the use of metal members. The main purpose is to provide a hinge in which no metal lump remains after incineration.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, the hinge according to the present invention comprises a first mounting piece (A) made of synthetic resin and a second mounting piece (B) made of synthetic resin, and comprises the first mounting piece (A). A vertical shaft (1) with an outer peripheral surface exposed at one side edge is integrally molded, and the shaft (1) of the first mounting piece (1) is formed at one side edge of the second mounting piece (B). ) Is formed integrally with a vertical cylindrical connecting part (3) having a bearing hole (3a) into which the shaft (1) is attached to the peripheral wall of the cylindrical connecting part (3). A vertical slit (3b) for fitting the shaft into the bearing hole (3a), and a part of the gap (L) between the slit (3b) is smaller than the diameter of the shaft (1). The structure has been adopted.

[0005]

[Action]

 The hinge configured as described above is formed by pressing the shaft (1) of the first mounting piece (A) against the slit (3b) of the tubular connecting portion (3) of the second mounting piece (B). (3b) elastically expands due to the elastic properties of the synthetic resin material, and the shaft (1) can be fitted into the bearing hole (3a) of the tubular connecting portion (3). This allows the left and right mounting pieces (A) and (B) to be easily connected with one touch. The hinge assembled in this way is mainly used as an opening / closing window for a casket.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention, in which the present invention is applied to a hinge of a so-called "leaf butterfly" type. This hinge is composed of a plate-shaped first mounting piece (A) made of synthetic resin and a plate-shaped second mounting piece (B) also made of synthetic resin. A plurality of, for example, four vertical shafts (1), whose outer peripheral surfaces are exposed, are arranged on one side edge of the first mounting piece (A) on a coaxial line at appropriate intervals, It is integrally formed with the first mounting piece (A) together with the stays (2) supporting the shaft.

[0007] Further, four vertical cylinders having a bearing hole (3a) into which the shaft (1) of the first mounting piece is rotatably fitted are provided at one side edge of the second mounting piece (B). The connecting portions (3) are arranged on the coaxial line with the same space as the shafts (1), and are integrally formed with the second mounting piece (B). Vertical slits (3b) for fitting the shaft (1) into the bearing hole (3a) are formed in the same direction on the peripheral wall of the tubular connecting portions (3).

Therefore, in the present invention, in the slits (3b) of the upper and lower cylindrical connecting portions (3) and (3), the minimum gap (L) of a part thereof, for example, an intermediate portion, of the shaft (1) is set. It is formed smaller than the diameter. As shown in FIG. 2, it is preferable that the slit (3b) is formed so as to spread outward in a trumpet shape in the cross-sectional shape, which facilitates insertion of the shaft (1). . When forming this minimum gap (L), as shown in the figure, a through hole (3c) is provided on the peripheral surface on the side opposite to the side where the slit (3b) of the tubular connecting part is provided, and the resin is passed through this through hole. By removing the split mold for molding, only the upper and lower split molds (in Fig. 2) are required, which allows multiple molds and lowers the product unit price.

In the hinge configured as described above, when the shaft (1) of the first mounting piece (A) is pressed against the slit (3b) of the tubular connecting portion (3) of the second mounting piece (B). The slit (3b) is elastically expanded due to the elastic properties of the synthetic resin material, and the shaft (1) can be fitted into the bearing hole (3a) of the tubular connecting portion (3). This makes it possible to assemble the hinge by simply connecting the left and right mounting pieces (A) and (B) with one touch.

In the above embodiment, an example in which four shafts (1) and four tubular connecting portions (3) are provided is shown, but the number is not specified and the number required from one is required. It is possible to set up to. Further, the slit (3b) formed in the tubular connecting portion (3) may be directed upward as opposed to downward in FIG. 2, or may be formed in any direction as required.

Further, according to the present invention, the left and right connecting pieces (A) are changed by changing the diameter of the shaft (1), the wall thickness of the tubular connecting portion (3), or the gap of the slit (3b) during manufacturing. ) And (B) can be changed.

Although a representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment structure, and may be appropriately configured as long as it has the constituent requirements and has an effect. It can be changed and implemented.

[Effect of device]

 As described in detail above, the present invention comprises a first mounting piece (A) made of synthetic resin and a second mounting piece (B) made of synthetic resin. A vertical shaft (1) with an exposed outer peripheral surface is integrally molded on the side edge, and the shaft (1) of the first mounting piece is attached to one side edge of the second mounting piece (B). A vertical cylindrical connecting part (3) having a bearing hole (3a) into which the shaft is rotatably fitted is integrally formed, and the shaft (1) is attached to the peripheral wall of the cylindrical connecting part (3). A vertical slit (3b) for fitting in the bearing hole (3a) is formed, and the minimum gap (L) of the slit (3b) is smaller than the diameter of the shaft (1). , Press the shaft (1) of the first mounting piece (A) into the slit (3b) of the tubular connecting part (3) of the second mounting piece (B) and elastically fit into the bearing hole (3a). By mating, you can easily assemble the hinge by connecting the left and right mounting pieces (A) and (B) with one touch. As a result, the number of assembly steps for the hinge and the components can be omitted to reduce costs, and since no metal parts are used at all, metal lumps remain during incineration as described at the beginning. There is an excellent effect such as the elimination of
