Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a drawer container that is a combination of a case-shaped container body and a storage tray that can be inserted into and removed from the opening of the case-shaped container body.

<Prior Art> As a conventional drawer container of this type, the technology disclosed in Japanese Utility Model Laid-Open No. 59-89826 developed by the applicant of the present application is known.

In this technique, a swing arm is swingably attached to the end of a saucer via a pin shaft, a pin is planted at the tip of the saucer, and a central groove and a hook are provided inside a container housing the saucer. The present invention relates to a drawer container which is provided so as to be connected with a groove and is configured so that the pin of the swing arm is introduced into and engaged with the hook-shaped groove.

<Problems to be solved by the invention> However, in the drawer container described above, a swing arm of a separate member must be attached to the end of the tray via a pin shaft, and a pin must be planted in this swing arm. Therefore, there are problems that the number of parts is large and the assembling work is difficult.

Further, in the above technique, the saucer is locked in the container by introducing and locking the pin of the swing arm into the hook-shaped groove, but the hook-like introduction process is complicated and once it is introduced. However, there is a problem in that the engagement between the two may be released due to vibration and the like, and there is no responsiveness when opening and closing the lock.

The present invention relates to a completely new technique developed in view of the above-mentioned problems of the related art.

<Means for Solving the Problems> The present invention relates to a drawer container including a case-shaped container body having one side surface opened, and a storage tray that can be stored in the case-shaped container body so as to be freely drawn from the opening. A means for constantly urging the storage tray outward is provided between the container body and the container, and an oscillating member having engaging means on one of the adjacent surfaces of the case container body and the storage tray. A moving arm integrally projecting in a swingable manner, and a curved guide groove capable of guiding the swinging arm while swinging the swinging arm, and an engaging means engaging with the engaging means. It is a drawer container characterized by being configured by providing.

<Operation> As described above, in the drawer container according to the present invention, the swing arm having the engaging means is swingably integrally projected to one of the adjacent surfaces of the case-shaped container body and the storage tray. The rocking arm is provided with a curved guide groove for guiding the rocking arm while rocking the rocking arm and engaging means for engaging with the engaging means. The storage tray can be securely engaged and fixed to the case-shaped container main body by introducing the above into the curved guide groove and combining both engaging means, and the storage tray is further pressed to move the swing arm again. By doing so, both engaging means can be released and the storage tray can be pulled out from the case-shaped container body.

<Embodiment> An embodiment of the drawer container according to the present invention will be described in detail with reference to the drawings. In FIGS. 1 to 6, 1 is a rectangular storage tray, and the side wall center is The swing arm 2 is integrally provided so as to swing freely. This swing arm 2
A hook 3 is integrally provided on the tip side surface of the rocking arm 2, and a guide boss 4 is integrally projected on the lower surface of the tip end of the swing arm 2.

Next, 5 is a case-shaped container main body, and an opening for accommodating the storage tray 1 is formed in the lower part thereof. A curved guide groove 6 that can guide the guide boss 4 of the swing arm 2 is formed in the rear central plane of the case-shaped container body 5, and a predetermined lateral position of the curved guide groove 6 is provided. A hook 7 capable of meshing with the hook 3 of the swing arm 2 is provided. A stopper 8 is provided adjacent to the hook 7.

The curved guide groove 6 is composed of a central groove 6b provided substantially linearly from the inlet portion 6a, and a curved return groove 6c provided across the upper end bent portion of the central groove 6b and the inlet portion 6a. The boundary between the central groove 6b and the curved return groove 6c, and the curved return groove 6c
A step A and a step B are provided at the boundary between the entrance and the entrance 6a. In the step A, the central groove 6b is higher than the curved return groove 6c, and in the step B, the curved return groove 6c is formed higher than the inlet portion 6a.

Therefore, when the storage tray 1 is deeply inserted into the case-shaped container body 5, the guide boss 4 of the swing arm 2 is first introduced into the central groove 6b from the inlet 6a by the action of the step B, and the case-shaped container body 5 is further introduced. When is pressed, the guide boss 4 is
It is configured so that it cannot enter the curved return groove 6c beyond the step A from 6b and return to the central groove 6b again by the action of the step A.

Reference numeral 9 in the drawing denotes a spring mechanism provided on both upper sides in the case-shaped container body 5, and is configured so that the storage tray 1 deeply inserted in the case-shaped container body 5 can always be urged toward the inlet. ing.

Since the drawer container according to the present invention has the above-mentioned structure, when the storage tray 1 is inserted into the case-shaped container body 5 and then pushed, the guide boss 4 of the swing arm 2 is inserted into the curved guide groove 6. The swing arm 2 is introduced from the portion 6a into the central groove 6b and is prevented from being inserted too deeply by the stopper 8. In this state, the hooks 3 and 7 are meshed with each other and the biasing force of the spring 9 is applied. Against this, the storage tray 1 is fixed in the case-shaped container body 5.

Next, when the storage tray 1 is pulled out from the case-shaped container main body 5, the storage tray 1 is pressed further deeply into the case-shaped container main body 5, so that the guide boss 4 of the swing arm 2 goes over the step A and returns to the curved shape. The guide boss 4 is introduced into the groove 6c, and at the same time, the guide boss 4 is guided over the step B by the action of the spring 9 to the inlet portion 6a, so that the swing arm 2 is extracted from the curved guide groove 6.
The storage tray 1 can be pulled out from the case-shaped container body 5.

In the above embodiment, the hook 3 is provided on the side surface of the tip end of the swing arm 2 and the hook 7 is provided around the groove of the curved guide 6 of the case-shaped container body 5, but as shown in FIG. When the reverse taper recess 7a is formed in the guide groove 6, the swinging arm 2 is engaged in the curved guide groove 6 by dropping the guide boss 4 into the reverse taper recess 7a. Can be done. Therefore, the engagement means for the storage tray 1 and the case-shaped container body 5 is not limited to the one configured by the hooks 3 and 7 described above, and various types can be used.

<Advantages of the Invention> Since the drawer container according to the present invention has the structure and operation as described above, it is integrally connected to the storage tray or the case-shaped container body without forming the swinging arm, the pin, etc. by separate members. Can be installed, the number of parts is small and the assembly work is easy,
Moreover, since the engaging means of the storage tray and the case-shaped container main body are engaged with each other by a hook or a reverse taper recess without providing a special deformed hook groove, the swing arm can be smoothly rotated to prevent backward movement. Further, when a step is provided at a predetermined position of the curved guide groove, a small sound or vibration is generated when the guide boss crosses the step, and a feeling of finishing at the time of opening and closing can be provided. And so on.
