DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting / lowering mechanism for a hanger rod which is always above a storage box body and is used by being pulled down when necessary.

[0002]

2. Description of the Related Art Conventionally, as this type of lifting mechanism, there has been known a type in which a swing arm is used to largely swing forward and downward. However, in this known swing type, the arm for supporting the hanger rod needs to be lengthened since the hanger rod must be swung greatly from the upper storage position to the lower front take-out position, and accordingly, the arm is required. The load such as bending moment and torsion increases, and each member such as the arm, the support shaft, and the return damper needs to have high strength, and the entire device becomes large-scale and the cost increases. there were.

[0003]

Accordingly, the present invention employs a unique mechanism in which a hanger rod is first drawn forward along a rail like a drawer and then moved downward via a link. Accordingly, the main object of the present invention is to reduce the size of the structure and to solve the above-mentioned conventional disadvantages.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the hanger rod elevating mechanism according to the present invention, the extension rail 3 that can be pulled out substantially horizontally toward the front of the storage box body is attached to the inner side surface 1a of the fixed side plate 1 of the storage box body A. The hanger rod holding member 6 is attached to the slide rail 3b of the payout rail 3 through links 4 and 4 that can rotate within a predetermined angle range, and the hanger rod holding member 6 is horizontally attached to the hanger rod holding member 6. Is attached, and a handle 7 extending downward is provided on the hanger rod 2 or the hanger rod holding member 6,
The structure is such that the hanger rod 2 can be moved up and down by rotating the links 4 and 4 with the handle 7 at the position where the hanger rod 2 is pulled out to the front of the storage box body A.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It is preferable to provide a posture holding means 5 for holding a rising posture and a descending posture of the hanger rod 2 by the rotation of the link 4. It is preferable that the attitude holding means 5 is constituted by an elastic machine 5a for forcing the link 4 between the raised position and the lowered position of the storage body 2 at the dead point.

The feed-out rail 3 includes a fixed rail 3a fixed to the inner side surface 1a of the fixed side plate 1, and a slide rail 3b drawn directly from the fixed rail 3a or in a three-stage manner via an intermediate slide rail 3c. And formed by The elastic machine 6 may be a coil spring or a fluid pressure damper having a built-in spring.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The lifting mechanism according to the present invention will be described below with reference to the embodiments shown in FIGS. In the drawing, reference numeral 1 denotes a fixed side plate of a storage box body A such as a locker having an opening on the front surface, and feed-out rails 3 and 3 are attached substantially horizontally to the inner surfaces of the side walls 1a and 1a of the fixed side plate 1. I have.
The feed-out rail 3 is formed by a fixed rail 3a and a slide rail 3b that can be pulled out from the fixed rail 3a via an intermediate slide rail 3c in a three-stage manner. The fixed rail 3a is fixed to the inner surface of the side surface 1a. ing.

A hanger rod holding member 6 is attached via a four-point link mechanism formed by a pair of links 4 parallel to the slide rail 3b. The rod 2 is attached in a bridge state. One end of the link 4 is swingably connected to the slide rail 3b with the pivot 4a as a fulcrum, and the other end is connected to the hanger rod holding member 6 via the pivot 4b.

Further, a handle 7 extending downward is provided on the hanger rod holding member 6 so as to be swingable via a pivot 7a. The handle 7 allows the hanger rod 2 to be pulled out to the front of the storage box body A, and the links 4, 4 are rotated at the pulled-out position to move the hanger rod 2 up and down. ing. Further, in this embodiment, while the hanger rod holding member (6) moves from the position of FIG. 1 to the front position of the storage box body (A) as shown in FIG. 2, the hanger rod holding member (6) is lowered. A guide plate (8) for preventing movement is provided along the hanger rod holding member 6. With such a configuration, the hanger rod 2 can be pulled forward along the extension rails 3 and 3 and can be moved downward by the rotation of the links 4 and 4.

Further, there is provided a posture holding means 5 for temporarily holding the ascending posture and the descending posture of the housing 2 due to the rotation of the links 4, 4. The attitude holding means 5 includes a resilient device 5a which is connected to an intermediate portion of one of the links 4 from a pivot point 5b provided on the slide rail 3b and constantly presses the link 4. As shown in FIGS. 2 and 3, this ammunition device 5a is forced to move the hanger rod 2 up and down at a dead point on a line X connecting the pivot point 5b and the link rotating shaft 4a. It is provided to be. Although the elastic machine 5a shown in the above embodiment uses a damper which has a spring and fluid pressure built therein and is always pressed in the pushing direction, an index spring as shown in FIG. 5 may be used instead. good. The links 4, 4 and the ram 5a are of course installed so as not to interfere with each other during operation. Note that reference numeral 9 in the drawing denotes a stopper that regulates the rotation range of the links 4 and 4.

In the above configuration, when necessary, the handle 7 is pulled out of the storage position shown in FIG. 1, and the hanger rod 2 is extended to the front position shown in FIG.
If the link is pulled downward as it is, the links 4 and 4 can be rotated and moved to the lowered position as shown in FIG.
When the storage body 2 is lifted upward from the lowered position in FIG. 3 and the pivot point 5b of the armature 5a to the link 4 exceeds the dead point on the line X, the force of the armature 5a increases the lifting force of the hanger rod 2. And the lifting operation of the hanger rod 2 can be performed lightly.

Although the embodiments of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, as shown in FIG. 6, it is also possible to provide the extension rail 3 and the links 4 and 4 only on one side plate 1 so that the hanger rod 2 is cantilevered. Further, in the above embodiment, both the attitude holding means 5 and the guide plate 6 are provided, but either one of them can be omitted. Furthermore, each of the links 4 and 4 may be formed as a pair. In addition, the present invention can be carried out by appropriately modifying it within the scope having the constituent features, achieving the object of the present invention, and achieving the following effects.

[0013]

As described above, according to the present invention, the hanger rod is drawn out to the front of the storage box along the payout rail and then moved downward through the link. Can be set short, which can significantly reduce the load such as bending moment and torsion applied to the link, and can reduce the size of each part.Therefore, there is little space for incorporating the mechanism and the storage box There is an excellent effect that the storage space can be effectively secured, and the cost can be reduced by simplification and compactness of the mechanism.
