Description

  The present invention relates to a mounting structure for attaching a mirror door to a resin-made mirror cabinet body using upper and lower hinges.

  Conventionally, as disclosed in Patent Document 1, there is a mirror cabinet in which a mirror door is attached to a cabinet body using upper and lower hinges.

Japanese Utility Model Publication No. 58-12337

In the mirror cabinet disclosed in Patent Document 1 above, a stopper is provided on the lower hinge, and the opening angle of the mirror door is regulated by this stopper. It was not of a structure that could accommodate expansion and contraction.
That is, when the cabinet body is made of polypropylene (PP) having excellent chemical resistance, polypropylene has a large post-shrinkage and linear expansion coefficient, and the expansion and contraction due to temperature change is large. Due to the vertical expansion and contraction due to temperature changes, the distance between the upper and lower hinges fixed to the mirror cabinet body also changes greatly, and a large load is applied to the hinges, so that the mirror door operates normally. There was a problem that it could not be maintained.

An object of the present invention is to provide a mirror cabinet door mounting structure in which a hinge is not subjected to a heavy load and the mirror door can normally maintain an opening / closing operation. To achieve at least a part of this object, the following means are provided. I took it.
In the mounting structure in which the mirror door is attached to the resin cabinet body using the upper and lower hinges, the lower hinge is provided with a stopper for regulating the opening angle of the mirror door, and the upper hinge The gist is that there is no stopper, and the upper hinge is configured to be slidable up and down in response to vertical expansion and contraction due to a temperature change of the cabinet body.

Even when the cabinet body expands and contracts in the vertical direction due to temperature changes, the upper hinge slides in the vertical direction in response to the expansion and contraction. That is, when the hinge slides in the vertical direction well, even if the cabinet body expands or contracts in the vertical direction, a large load is not applied to the upper and lower hinges, and the mirror door can maintain a normal opening / closing operation.
Also, since the lower hinge is equipped with a stopper, the impact that occurs when the mirror door is opened and closed is applied to the lower hinge, the upper hinge that does not have a stopper is not subject to impact, and the upper hinge Since it is not damaged, the situation where the mirror door falls off when the hinge is damaged is satisfactorily prevented.

  Further, the present invention provides a mounting structure in which a mirror door is attached to a resin cabinet body using upper and lower hinges, and the lower hinge is provided with a stopper for regulating an opening angle of the mirror door, There is no stopper on the hinge, and the upper hinge is configured such that a main body attachment side member fixed to the cabinet main body and a door attachment side member fixed to the mirror door are connected by a vertically long shaft portion. The gist of the present invention is that the main body attachment side member is configured to be slidable up and down with respect to the door attachment side member.

In this way, the upper hinge is connected to the main body mounting side member and the door mounting side member by the vertically long shaft portion. Since the main body mounting side member slides in the vertical direction relative to the door mounting side member, even if the cabinet main body expands or contracts in the vertical direction, a large load is not applied to the upper and lower hinges, and the hinges are prevented from being damaged. Therefore, the mirror door can maintain a normal opening / closing operation.
Also, since the lower hinge is equipped with a stopper, the impact that occurs when the mirror door is opened and closed is applied to the lower hinge, the upper hinge that does not have a stopper is not subject to impact, and the upper hinge Since it is not damaged, the situation where the mirror door falls off when the hinge is damaged is satisfactorily prevented.

  Further, in the mounting structure for attaching the mirror door to the resin cabinet body using the upper and lower hinges, the lower hinge is provided with a stopper for regulating the opening angle of the mirror door. The lower hinge is configured to be vertically slidable in response to vertical expansion and contraction due to temperature changes of the cabinet body, the upper hinge has no stopper, and the upper hinge is slidable vertically The gist is that it is impossible.

By constituting in this way, when the vertical expansion and contraction due to temperature change occurs in the cabinet body, the lower hinge slides in the vertical direction corresponding to this, and a large load is not applied to the hinge, The mirror door can maintain a normal opening and closing operation even if the cabinet body is vertically expanded and contracted.
In addition, since the lower hinge is equipped with a stopper, the impact that occurs when the mirror door is opened and closed is received by this lower hinge. Since the hinge is not destroyed, the mirror door will not fall off.
Further, the upper hinge can be constituted by a stopper and an inexpensive hinge having no sliding function.

  Further, in the mounting structure for attaching the mirror door to the resin cabinet body using the upper and lower hinges, the lower hinge is provided with a stopper for regulating the opening angle of the mirror door. The lower hinge includes a main body mounting side member fixed to the cabinet main body and a door mounting side member fixed to the mirror door by a vertically long shaft portion, and the main body mounting side member via the shaft portion. Is configured to be slidable up and down with respect to the door mounting side member, and there is no stopper on the upper hinge, and the upper hinge is configured not to slide up and down.

In this way, the lower hinge is connected to the main body mounting side member and the door mounting side member by the vertically long shaft portion, so that when the vertical expansion and contraction due to temperature change occurs in the cabinet body, the shaft portion is Since the main body mounting side member slides vertically with respect to the door mounting side member, even if the vertical expansion and contraction of the cabinet main body occurs, a large load is not applied to the upper and lower hinges, and the hinges are prevented from being damaged. The mirror door can maintain a normal opening / closing operation.
Also, since the lower hinge is equipped with a stopper, the impact that occurs when the mirror door is opened and closed is applied to the lower hinge, the upper hinge that does not have a stopper is not subject to impact, and the upper hinge Since it is not damaged, the situation where the mirror door falls off when the hinge is damaged is satisfactorily prevented.

Next, the form for implementing this invention is demonstrated using an Example.
FIG. 1 is a perspective configuration diagram of a mirror cabinet with a mirror door opened.
The mirror cabinet 1 has a central mirror door 3A attached to the front surface of the cabinet body 2 via an upper hinge 8A and a lower hinge 8B, and sleeve mirror doors 3B and 3B attached to the left and right sides thereof.
The cabinet body 2 is made of polypropylene (PP), has high chemical resistance, and storage chambers S, S, S are formed inside, and a plurality of storage trays 4, 4 are provided in each storage chamber S. ing. Further, illumination lamps 5 and 5 are provided on the upper end side of the cabinet body 2, and illumination covers 6 and 6 are provided on the front surfaces of the illumination lamps 5 and 5.

An upper hinge 8A and a lower hinge 8B are respectively attached to the upper and lower mounting surfaces 2a and 2a on the front surface of the cabinet body 2. The upper hinge 8A and the lower hinge 8B are upper frames on the upper ends of the mirror doors 3A, 3B and 3B, respectively. 7a and the lower frame 7b on the lower end side.
Each of the mirror doors 3A, 3B, 3B is composed of a glass mirror and hardly expands or contracts due to a temperature change. However, since the cabinet body 2 is made of polypropylene, the post-shrinkage and the linear expansion coefficient are large. It expands and contracts due to temperature changes. For example, in the winter season, the vertical dimension of the cabinet body 2 shrinks.

  When the cabinet body 2 expands and contracts, the vertical dimension between the upper and lower mounting surfaces 2a and 2a changes, so that the upper and lower upper hinges 8A and 8B are subjected to loads such as excessive twisting, and the mirror doors 3A, 3B, In this example, even if the cabinet body 2 expands and contracts due to temperature change, the dimension between the upper and lower upper hinges 8A and 8B does not change, and the upper and lower upper hinges 8A, The space between the lower hinges 8B is always the same, and the upper hinge 8A and the lower hinge 8B are devised so that an unreasonable load is not applied.

  Hereinafter, the attachment structure of the central mirror door 3A will be described as an example, but the attachment structure of the sleeve mirror doors 3B and 3B is the same.

The upper end side of the central mirror door 3A is attached to the cabinet body 2 via an upper hinge 8A, and the lower end side of the central mirror door 3A is attached to the cabinet body 2 via a lower hinge 8B.
First, the configuration of the lower hinge 8B will be described with reference to the perspective view of FIG. 2 and the sectional view of FIG.
The lower hinge 8B includes a main body attachment side member 81, a door attachment side member 82, and a shaft portion 83 that couples both of them so as to be rotatable.
The body attachment side member 81 has a substantially horizontal arm portion 81b protruding integrally from the lower end of a fixed portion 81a attached to the attachment surface 2a of the cabinet body with three screws 11, 11, 11. A shaft hole 85 into which the shaft portion 83 can be loosely inserted is formed in the portion 81b.

One door attachment side member 82 is attached to the lower frame 7b of the lower end of the central mirror door 3A with two screws 10 and 10, and the upper end of the shaft portion 83 is fixed by crimping. A stopper 84 for restricting rotation is integrally formed at the tip of the shaft portion 83 side of the member 82, and a bearing arm portion 82a is formed substantially horizontally at the lower end of the stopper 84. The lower end of the shaft portion 83 is caulked and fixed to the bearing arm portion 82a by the caulking fixing portion 83a.
Further, the sliding member 13 is interposed between the upper and lower surfaces of the shaft hole 85 and the door mounting side member 82, and the sliding member 13 makes the door mounting side member 82 smooth with respect to the main body mounting side member 81. It can be rotated in a horizontal plane.
As described above, the door attachment side member 82 rotates with respect to the main body attachment side member 81 around the shaft portion 83, and when it reaches a predetermined angle, the rotation is restricted by contacting the stopper 84. That is, the opening angle of the central mirror door 3 </ b> A is configured to be regulated by the stopper 84.

Next, the configuration of the upper hinge 8A will be described with reference to the perspective view of FIG. 4 and the sectional view of FIG.
In the upper hinge 8 </ b> A, a main body attachment side member 81 and a door attachment side member 82 are connected by a shaft portion 83 so as to be rotatable.
The main body attachment side member 81 protrudes from the upper end of the fixing portion 81a attached and fixed to the attachment surface 2a of the cabinet main body with the screw 11 so as to project integrally in a substantially horizontal manner to form an arm portion 81b.
The door attachment side member 82 is formed with a shaft hole 85 into which the shaft portion 83 is loosely inserted, and is attached and fixed on the upper frame 7a of the central mirror door 3A with screws 10 and 10.
The shaft 83 has its upper end crimped by a caulking fixing portion 83a and is fixed to the arm portion 81b of the body attachment side member, and a retaining portion 83b that protrudes outward in a bowl shape is formed at the lower end of the shaft 83. Has been.

In this example, the upper clearance a from the shaft hole 85 to the arm portion 81b is set to a clearance that is 0.6% or more of the vertical dimension between the upper hinge 8A and the lower hinge 8B, for example. The lower clearance b from the upper hinge 8A to the retaining portion 83b is set to be 0.3% or more of the dimension between the upper hinge 8A and the lower hinge 8B.
That is, the upper clearance a is set to a clearance that can absorb the shrinkage when the cabinet body 2 contracts in the vertical direction when the temperature is cold, and the lower clearance b is set to a clearance that can absorb the extension of the cabinet body 2 at a high temperature. ing.

In this way, when the mirror door 3A is attached using the lower hinge 8B shown in FIGS. 2 and 3 and the upper hinge 8A shown in FIGS. 4 and 5, the cabinet body 2 is moved vertically by temperature change. When it expands and contracts, the body attachment side member 81 of the upper hinge 8A slides and moves in the vertical direction via the shaft portion 83, and this causes a load on the upper hinge 8A and the lower hinge 8B. Therefore, even if the cabinet body expands and contracts in the vertical direction, the mirror door 3A can maintain a normal opening / closing operation.
The upper hinge 8A has no stopper, and the lower hinge 8B is provided with the stopper 84. Therefore, the impact when the mirror door 3A is opened and closed is applied to the stopper 84 and is damaged by a large impact. The upper hinge 8A is not damaged because the lower hinge 8B side is not subjected to any impact. The upper hinge 8A favorably supports the mirror door 3A on the cabinet body 2 side. Therefore, unlike the conventional case, the situation that the mirror door 3A falls off the cabinet body 2 due to the damage on the upper hinge 8A side does not occur.
