Abstract

(57) [Summary] (with amendments) [Purpose] In order to improve the usability when opening and closing doors of lockers, etc., the door can stop at a desired position, and the door can be easily opened without the user paying attention. To provide a pivot structure for a door that can be closed and does not require an increase in assembly man-hours. [Structure] The simple structure of the cam 9 provided around the pivot shaft 7 and the leaf spring 11 that abuts the cam improves the usability when opening and closing the door. Furthermore, by providing the cam integrally with the hinge component, the cam can be assembled at the same time as the hinge structure is assembled, and the number of assembly steps does not increase.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

Regarding the pivot structure of the door, especially when the door is open like a locker, it is difficult to put in and take out stored items. This invention relates to a door pivot structure suitable for use in storage furniture and the like.

0002

[Conventional technology]

Traditionally, locker doors, for example, were simply pivoted at either the left or right edge. Even if the user closes the door, the door does not close completely, leaving the door open half-open. There were times when I felt like I was in a bad situation.

0003 Therefore, we developed a structure that always biases the door in the direction of closing using a spring, etc., and A magnet is installed on the edge of the opening so that the door is always completely closed when it closes close to the opening. However, if the door is always biased in the closing direction, it will be difficult to load the baggage with the door open. Operations such as putting in and taking out can be troublesome, and if a magnet is installed between the door and the edge of the opening, the door can be opened with force. There are problems such as the door opening again due to the reaction when it is closed, and in either case, it is difficult to use the door. There was a problem of decreased convenience. In addition, apart from the hinge structure on the door and main body opening, Each of the above-mentioned structures must be provided, resulting in an increase in the number of assembly steps.

0004

[Problem that the idea aims to solve]

In view of these problems in the conventional technology, the main purpose of the present invention is to In order to improve the convenience of use when opening and closing the door, the door can be stopped at a desired position. The door can be easily closed without the user paying attention, further increasing the number of assembly steps. The purpose of the present invention is to provide a pivot structure for a door without a door.

[0005]

[Means to solve the problem]

According to the present invention, this purpose is to open and close the door using a hinge at the opening of the main body. A pivot structure for freely pivoting, the main body side and the door side being either a cam provided integrally with one of the hinge components and around the pivot; and the main body. and the door side, and the free end portion is provided on the cam surface of the cam. a leaf spring resiliently abutting the cam, and the cam is in one or more open positions and The leaf spring may be configured to bias the door toward one of the fully closed positions. This is achieved by providing a door pivot structure characterized by:

[0006]

[Effect]

In this way, it is integrally attached to the hinge component of either the door or the main body, and A structure in which a leaf spring provided on either side is brought into contact with a cam provided around the other side. By doing so, the door can be biased toward the desired position according to the cam shape. Ru. In addition, by providing the above-mentioned cam integrally with the hinge component, the hinge structure can be easily assembled. The cam can be assembled at the same time.

[0007]

【Example】

Hereinafter, the present invention will be described in detail with reference to specific embodiments with reference to the accompanying drawings.

[0008] Figure 1 is an enlarged cross-sectional view of the hinge part of a locker to which the present invention is applied. , FIG. 2 is a perspective view of the main part thereof.

[0009] The locker body 1 has an inlet opening for a receiving chamber 2 defined within the locker body 1. One side of the hinge 5 is connected via the bracket 4 to pivotally support the door 3 so that it can be opened and closed. Part 6 is fixed. A cylindrical bearing portion 6a is formed at the free end of this component 6. The shaft 7 passes through the shaft. In addition, the other component part 8 of the hinge 5 is on the door 3 side. The pivot 7 passes through the bearing portion 8a. Therefore, the door 3 has hinges 5 The rocker body 1 is pivotally supported by a component 8, a pivot 7, and a component 6.

0010 The bearing part 6a of the component part 6 extends vertically, and the pivot 7 in the center of the bearing part 6a extends vertically. A cam portion 9 is formed around the. In addition, around the cam part 9 of the component part 6, An opening 6b is provided through which a leaf spring 11, which will be described later, can be inserted. Here, the component By providing the cam part 9 and the opening 6b in the center of the bearing part 6a of 6, The strength of the hinge 5 does not decrease.

[0011] A leaf spring 11 fixed to the door 3 side is in contact with a cam surface 10 of the cam portion 9. This leaf spring 11 is urged toward the cam surface 10 by its own spring force. It is something that exists. Here, as shown in FIG. 2, when the door 3 is closed, the cam A leaf spring 11 abuts against a portion 10 a of the surface 10 , and the leaf spring 11 contacts the opening 6 of the component 6 . The state has entered b.

0012 Next, the operation procedure of this embodiment will be explained. First, when door 3 is closed, the above As shown, the leaf spring 11 enters the opening 6b and comes into contact with the portion 10a of the cam surface 10. The state will be as follows.

[0013] When the door 3 is opened from this state, the leaf spring 11 comes into contact with the cam surface 10 and the cam shape Due to the shape, the leaf spring 11 is deformed and becomes the state shown by the imaginary line A. Here, leaf spring 1 1 is in contact with a portion 10c of the cam surface 10, but this portion 10c and portion 10a Since the distance from the center of rotation O is shorter than that of the part 10b in between, When the leaf spring 11 is in the portion 10b, it is directed toward the portion 10a or the portion 10c. The door 3 will be biased, that is, the door 3 will be biased at a predetermined angle (actually about 45 degrees). When the door 3 is closed, the door 3 reliably closes the opening.

[0014] Next, when the door 3 is further opened from the state shown by the imaginary line A, the leaf spring 11 is removed from the portion 10c. After passing through the part 10d which is relatively far from the center O, the distance from the center O is again is in the state of an imaginary line B in which it abuts a relatively close portion 10e. A board is placed on this part 10e. The opening degree of the door 3 when the spring 11 is present is approximately 120°, and the This angle is determined as the maximum opening degree of the door 3 by a door etc. Even in this state Since the portion 10e is shorter from the center O than the preceding portion 10d, the door 3 is It will be held in this position.

[0015] When the door 3 is closed from the state of this imaginary line B, the leaf spring 11 first comes into contact with the part 10c. The leaf spring stops once in the state of imaginary line A, and then completely closes the opening. 11 will move to a position where it comes into contact with the portion 10a.

[0016] FIG. 3 is a partial plane showing a portion similar to the cam portion in FIG. 1 showing a modified example of this embodiment. FIG. The cam surface 20 of the cam portion 19 in FIG. 3 has a pinion shape. The protruding contact portions 21a of the leaf spring 21 contact the plurality of recesses, and the door 3 is moved in multiple stages. It is designed to stop and hold with a click feeling.

[0017]

[Effect of the idea]

As is clear from the above explanation, according to the pivot structure based on the present invention, the pivot The door has a simple structure consisting of a cam installed on the door and a leaf spring that comes into contact with the cam. The convenience of use when opening and closing is improved. In addition, the above cam is integrated into the hinge component. By doing so, the cam can be assembled at the same time as the hinge structure. The number never increases. From the above, the effects of the present invention are significant.
