Description

  The present invention relates to a hinge mechanism used for a container or the like.

  For example, a soap box that stores one soap has a basin-shaped container body that has an opening at the top and stores soap, and a basin-shaped container that is separate from the container body and is attached to the top of the container body. It consists of a lid. Then, when using soap, the lid is removed from the container body and left in the vicinity of the container body or superposed on the lower side of the container body.

  However, in the conventional soap box, the container main body and the lid are separate from each other, and thus the lid may be dropped when the lid is removed from the container main body.

  An object of the present invention is to provide a hinge mechanism that can be reversed and superimposed on the main body without separating the lid from the main body.

In order to achieve the above object, a hinge mechanism according to the present invention includes a main body having an opening, a lid that closes the opening of the main body with one surface facing the opening, and a hinge that connects the main body and the lid. A hinge mechanism that is openable and closable with respect to the opening via a pin of the hinge member, and a lower end portion of the hinge member is rotatably attached to the body by the pin, A shaft portion protruding from the body in the surface direction of the lid body is attached to the other end portion of the hinge member, and when the hinge member rotates, the both sides of the lid body can be reversed around the shaft portion, The lid body has a function of closing the opening of the main body with the one surface facing the opening on the main body, and the lid body is reversed by the pin so that the other surface of the lid body faces the opening. On the opening of the main unit And having a function to overlay.

  According to the hinge mechanism of the present invention, the hinge member is provided on the main body so as to be freely opened and closed, and the lid is connected to the hinge member via the shaft portion so as to be reversible, so that the lid is reversed without being separated from the main body. Can be superimposed on the main body.

The present invention will be described in detail based on the illustrated embodiment.
1 is an external perspective view of the embodiment, FIG. 2 is a longitudinal sectional view, FIG. 3 is an enlarged view of a hinge portion A, FIG. 4 is an enlarged view of a locking portion B, and the main body according to this embodiment is For example, it is a substantially elliptical soap box that can store one soap S. In this soap box, a lid 2 is connected to a main body 1 via a hinge member 3 and a pin 4 so as to be freely opened and closed. The main body 1, the lid 2 and the hinge member 3 are each molded from, for example, a transparent synthetic resin material, and then assembled.

  The main body 1 and the lid body 2 are combined with each other to accommodate approximately half of the soap S, respectively. In the hinge part A, the hinge member 3 is openable and closable in the direction of the center line of the main body 1, and the lid body 2 is rotatably connected to the hinge member 3 via an integral shaft part 5 and a flange part 6 at the tip thereof. Has been. In the locking portion B, a flexible piece 7 that slightly bulges outward is provided at the lower end of the lid 2 so as to face downward, and a locking projection 8 is formed on the inner surface of the flexible piece 7 inwardly. It is formed towards.

  On a part of the outer peripheral surface of the main body 1, a pair of support pieces 11 and 12 for supporting the hinge member 3 project outward. Further, in the locking part B, a recess 13 into which the flexible piece 7 of the lid 2 enters is formed on the outer peripheral surface of the main body 1, and the locking projection 8 of the lid 2 and the locking are formed on the back wall of the recess 13. A locking projection 14 for stopping is formed outward.

  The hinge member 3 includes side walls 21 and 22 that are supported by the support pieces 11 and 12 of the main body 1 via the pins 4, a top wall 23 that connects the upper edges of the side walls 21 and 22, and the side walls 21 and 22. The outer wall 24 connects the outer edges of the inner walls 25, and the inner wall 25 connects the inner edges of the side walls 21 and 22. The outer surfaces of the side walls 21 and 22 are stepped, for example, and substantially the same plane is formed by the outer surfaces of the upper portions of the side walls 21 and 22 and the outer surfaces of the support pieces 11 and 12, and the outer surfaces of the lower portions of the side walls 21 and 22 are the support pieces 11. , 12 is in sliding contact with the inner surface.

  The length of the inner wall 25 of the hinge member 3 in the vertical direction is substantially half of the length of the side walls 21 and 22 in the vertical direction, and interference between the inner wall 25 and the main body 1 is prevented. A groove portion 26 that receives the shaft portion 5 of the lid 2 is formed in the lower portion of the inner wall 25 with the lower portion as an opening. The width of the groove portion 26 in the left-right direction is often smaller than the outer diameter of the shaft portion 5 of the lid 2, and the shaft portion 5 having the flange portion 6 at the tip is press-fitted into the groove portion 26. Accordingly, the shaft portion 5 is prevented from falling off by press-fitting the shaft portion 5 into the groove portion 26, and the shaft portion 5 is prevented from being detached in the axial direction by the flange portion 6 at the tip of the shaft portion 5.

And the space | interval of the outer surface of the cover body 2 and the inner surface of the flange part 6 is made substantially equal to the thickness of the inner wall 25 of the hinge member 3, and the rattling between the cover body 2 and the hinge member 3 is prevented. Further, the lower end portion 3a of the hinge member 3 is brought into contact with the outer peripheral surface of the main body 1 when the hinge member 3 is opened by about 90 degrees, and the rotation of the hinge member 3 by about 90 degrees or more is restricted.

  When assembling the soap box, the side walls 21 and 22 of the hinge member 3 are arranged inside the support pieces 11 and 12 of the main body 1, and the support pieces 11 and 12 of the main body 1 and the side walls 21 and 22 of the hinge member 3 are arranged. The pins 4 are inserted into the respective holes (not shown) formed. Then, the shaft portion 5 of the lid body 2 is pushed into the groove portion 26 of the hinge member 3 from below. Accordingly, as shown in FIG. 5, the lid 2 is integrated with the main body 1 so as to be opened and closed in the direction of the arrow C and rotatable in the direction of the arrow D.

  When the soap S already stored is used, the flexible piece 7 of the lid 2 is bent outward so that the locking projection 8 of the lid 2 and the locking projection 14 of the main body 1 are locked. The lid 2 is opened as shown in FIG. At this time, the hinge member 3 follows the lid 2 and rotates around the pin 4, and the rotation of the hinge member 3 is performed when the lower end portion 3 a abuts on the outer peripheral surface of the main body 1 as shown in FIG. 7. Stop.

  Here, in order to make the soap S easy to use, the soap S is taken out from the main body 1, the lid body 2 is rotated by 180 degrees around the axis of the shaft portion 5, and the inverted lid body 2 is superimposed on the main body 1. . And soap S is accommodated in the inside of the cover body 2 inverted as shown in FIG. 8, FIG.

  In this embodiment, the hinge member 3 is provided on the main body 1 through a pin 4 so as to be freely opened and closed, and the lid 2 is connected to the hinge member 3 via a shaft 5 so that the lid 2 is rotatable. There is no separation from. Further, since the lid body 2 can be inverted about the axis of the shaft portion 5, the inverted lid body 2 can be superimposed on the main body 1 and the soap S can be placed on the lid body 2. it can.

  Further, although the hinge member 3 is supported on the main body 1 via a separate pin 4, the pin 4 can be integrated with the hinge member 3. In other words, the pin portions can be integrally provided on the side walls 21 and 22 of the hinge member 3, and the pin portions can be fitted into the hole portions of the support pieces 11 and 12, respectively.

It is an external appearance perspective view of an embodiment. It is a longitudinal cross-sectional view. It is an enlarged view of a hinge part. It is an enlarged view of a locking part. It is a perspective view in the state where a lid was opened. It is sectional drawing of a use condition. It is operation | movement explanatory drawing of a hinge member.
