Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the structure of an elevating shelf, and more specifically, focusing on the movement of the elevating shelf, making the overall structure compact and facilitating the elevating operation of the elevating shelf. It is related to the technology.

[Prior Art] Conventionally, the structure of an elevating shelf in which the elevating shelf 1 is connected to a fixed portion 2 via a parallel four-link mechanism 3 and the elevating shelf 1 is oscillated downward in a substantially forward direction is shown in FIG. A configuration as shown is conceivable.

[Problems to be Solved by the Invention] However, in such a structure, the lifting shelf 1
Is stored in a box-shaped storage section 18 having an opening at the front, the lower opening edge is lowered so that the rotation locus of the rear lower end 1a of the lifting shelf 1 does not hit the lower opening edge of the storage section 18. Is. However, in order to keep the lower edge of the opening downward so as to avoid the rotation locus of the rear lower end 1a of the lift shelf 1 as described above, a large dead space S is created in the storage portion 18, and the grip handle is placed on the lift shelf 1. There is a problem that the height of the grip handle becomes high and it becomes difficult to operate it when it is formed and operated to move up and down.

The present invention has been made in view of such problems,
The purpose of this is to focus on the movement of the lift shelf and to effectively use the dead space to lower the position of the grip handle without increasing the overall structure and to easily perform the lift operation of the lift shelf. The purpose of the present invention is to provide a structure of an elevating shelf.

[Means for Solving the Problem] In the structure of the lifting rack of the present invention, the lifting rack 1 is connected to the fixed portion 2 via the parallel four-link mechanism 3 to lower and swing the lifting rack 1 forward and downward substantially in parallel. It is a structure of an elevating shelf to be moved, and the elevating shelf 1 has a front frame 9 and a rear frame 10, and the front frame 9 is lower than the rear frame 10 and substantially coincides with a rotation locus of a lower end of the rear frame 10. It is characterized in that it is hung down to a height that is higher than the height, and that this hanging portion serves as a grip handle 24 when moving up and down.

[Operation] As described above, the elevating shelf 1 has the front frame 9 and the rear frame 10, and the front frame 9 is lower than the rear frame 10 and has a height that substantially coincides with the rotation locus of the lower end of the rear frame 10. The lower part of the front frame 9 is hung down to a height substantially corresponding to the turning locus of the lower end of the rear frame 10 by using this hanging part as a grip handle 24 for raising and lowering, and the parallel four-link The hanging grip handle 24 does not get in the way and does not need to be made large in size when the lifting rack 1 is swung up and down using the mechanism 3. The lifting / lowering shelf 1 can be easily lifted / lowered.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 shows storage furniture such as a shoe box,
An elevating shelf 1 is installed on the upper part of this storage furniture, and as shown in FIG. 2, it is pulled down to the front upper part of the lower storage part 8 so that articles such as shoes can be stored and taken out. The structure of the lifting shelf 1 will be described in detail below.

The front frame 9 and the rear frame 10 are each formed by bending, for example, a pipe material into a substantially square shape, and the front and rear frames 9 and 10 are connected by a connecting member 11. Then, a shelf material 13 is placed on an L-shaped shelf support material 12 that is also attached to connect the front and rear frames 9 and 10, so that articles such as shoes can be placed on these upper and lower multi-tiered shelf materials 13. is there. Such a lifting shelf 1 has both side plates
Upper storage part composed of 14, top plate 15, bottom plate 16 and back plate 17
It can be taken out from the storage posture stored in 18 to the take-out posture in which the lower storage portion 8 descends and swings forward. The configuration will be described in detail below.

A case 7 that serves as the fixed portion 2 is attached to the inner surface of the side plate 14 with screws 19. And the first link 20 and the second link 21
The lower end portions of the first links 20 are pivotally attached to the case 7 by pins 22, and the upper end portions of the first links 20 are rotatably connected to the connecting members 11 by the pins 22. Is rotatably connected to the rear frame 10 by a pin 22, and the first link 20 and the second
The link 21 becomes almost parallel, and the upper two pins 23,23
The parallel quadruple link mechanism 3 in which the line connecting the lines and the line connecting the lower pins 22 and 22 are substantially parallel to each other is configured. It is possible to swing up and down while moving in parallel.

In the case 7, the guide groove 4 is formed along the swing locus of the specific portion P of the second link 21 on the side of the parallel four-link mechanism 3. Then, the pin-shaped guided member 5 implanted in the specific portion P is inserted into the guide groove 4 so that the guided member 5 moves along the guide groove 4 as the lifting shelf 1 moves up and down. A spring 6 is housed in the case 7, one end of the spring 6 is engaged with the guided member 5 and the other end is fixed to the case 7 as the fixing portion 2, and the spring 6 raises the lifting shelf 1. Biased to the side to lighten the storage by raising the lifting shelf 1,
The elevating shelf 1 can be easily pulled down. The guide groove 4 is formed in a substantially arcuate shape, and the final end on the upper end side is set at a position where it slightly changes from the uppermost end to the lower end. A posture in which the backboard 14 is in the retracted posture [see FIG. 4 (a)]
It is preferable that the lift rack 1 is prevented from swinging downward even if the spring 6 is accidentally disengaged.

By storing the spring 6 in the case 7 in this way, the spring 6 is not exposed and the appearance is improved. Even if the spring 6 is accidentally detached, the spring 6 remains in the case 7 and the spring 6 scatters. It is to prevent it.

The front frame 9 of the elevating shelf 1 is hung below the rear frame 10 and to a height substantially corresponding to the rotation locus of the lower end of the rear frame 10. This hanging portion is used as a grip handle 24 for lifting and lowering. Then, the lower portion of the front frame 9 is hung down to a height substantially corresponding to the rotation locus of the lower end of the rear frame 10, and is hung down to swing up and down the lifting shelf 1 using the parallel four-link mechanism 3. The grip handle 24 does not get in the way and does not need to be made large in size, and the hanging grip handle 24 can be used to easily raise and lower the elevating shelf 1. In such a case, the front frame 9 and the rear frame 10 are formed by bending a pipe material, and
It is safe to hit other objects when moving up and down.

Needless to say, the present invention can be applied to a storage unit other than the shoe box.

[Advantages of the Invention] In summary, according to the present invention, the elevating shelf has the front frame and the rear frame, and the front frame is lower than the rear frame and has a height substantially corresponding to the rotation locus of the lower end of the rear frame. Since it hangs down, and this hanging part is used as a grip handle when moving up and down, the lower part of the front frame is hung down to a height that approximately matches the rotation trajectory of the lower end of the rear frame, and the parallel four-link mechanism is used to lift the shelf. The hanging handle does not get in the way even though it is oscillated up and down, and it is not necessary to make the entire size large, yet it is easy to move up and down the lifting shelf with the hanging handle. There are advantages.
