Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an underfloor storage elevating device suitable for use in an underfloor storage that moves a storage body up and down by power.

(Background technology and issues)

The present applicant has already proposed a storage device moving device that raises and lowers the storage device provided in the underfloor storage by a driving unit (power) (Japanese Utility Model Application No. 1-118482).

In this moving device, a guide mechanism for supporting the storage body so as to be displaceable, and one ends of a main arm and a sub arm connected via a rotation shaft are slidably mounted on movable rails provided on the storage body side, respectively. The other end is slidably mounted on a fixed rail, and the intermediate position between the other end of the main arm and the rotation shaft is rotatably connected to a fixed support shaft, and a sector gear is fixed to the other end of the main arm. And a drive mechanism for transmitting the rotation of the drive motor to the sector gear via a transmission gear mechanism.

〔Example〕

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

The underfloor storage is installed under the floor of the kitchen in the house, as indicated by reference numeral A in FIG. S denotes an opening provided on the floor F, and an opening / closing lid L is attached to the opening S. In addition, below the opening S, the lifting device 10 according to the present invention for raising and lowering the storage body (storage case) C is installed.

Next, the lifting device 10 will be described in detail with reference to FIGS.

First, the lifting device 10 includes the frame 1. Frame 1
As shown in FIG. 1 and FIG. 2, a pair of guide frame portions 3a and 3b and a pair of drive frame portions 6 are provided as divided bodies.
a and 6b are provided.

The guide frame 3a (same for 3b) has a cross section L
A pair of right and left guide rails 22x, which are provided with two upper and lower frame members 21a, 21b using a square bar, and formed in a C-shaped cross section.
Attach both ends of 22y to the inner surface side and connect. Guide rail 2
Sliders 23x and 23y are movably mounted on 2x and 22y, and constitute guide portions 2ax and 2ay for vertically guiding a storage body C described later. As shown in FIG. 5, the slider 23x (same for 23y) has a pair of spaced rollers 24m and 24n to be loaded on the guide rail 22x, and a support piece 25 protruding in the horizontal direction.

On the other hand, the driving frame portion 6a (same for 6b) is also formed in a rectangular frame shape by four frame members 31a, 31b, 31c and 31d using an L-shaped square bar, and between the left and right frame members 31b and 31d. A horizontal intermediate member 31e is erected, and a vertical intermediate member 31f is erected between the intermediate member 31e and the upper frame member 31a. Further, an elevation drive unit 4a using an X-arm mechanism unit 5a is mounted on the inner surface side of the drive frame unit 6a (same for the 6b side). The X arm mechanism 5a has a horizontal movable rail 32, and one end of a main arm 33 and one end of a sub arm 34 constituting the X arm are slidably mounted on the movable rail 32. Further, an intermediate portion between the main arm 33 and the sub arm 34 is connected via a rotating shaft 35 which is rotatable with respect to each other. In this case, the sub arm 34 is divided into two parts, each of which is disposed on both sides of the main arm 33 so as to sandwich the main arm 33 therebetween.
They are integrated through a rotating shaft 35. And the main arm 33
The intermediate position between the other end of the rotary shaft 35 and the intermediate member 31e is
It is rotatably attached to the fixed support shaft 37 (see FIG. 5) of the base plate 36 attached to 1f. A horizontal fixed rail 38 is attached to the intermediate member 31e. The other end of the sub arm 34 is slidably mounted on the fixed rail 38, and a sector gear 39 is fixed to the other end of the main arm 33.

On the other hand, the drive mechanism 51 is mounted on the base plate 36. The drive mechanism 51 includes a drive motor 52 and a transmission gear mechanism 53 as shown in FIG. 5, and the transmission gear mechanism 53 further includes a worm gear 5 provided on an armature shaft of the drive motor 52.
4, the worm wheel 55 that meshes with this worm gear 54
The worm wheel 55 has a pinion 56 coaxially integrated therewith, and the pinion 56 meshes with the sector gear 39.

.., 6a... Are assembled in advance for each frame unit, and are prepared for each frame unit.
At the time of installation, the respective frame portions 3a... 6a are alternately arranged to form four front, rear, left and right faces, and the respective frame portions 3a. As shown in FIG. 3, for example, as shown in FIG. 3, mounting portions 7a, 7b, 7c, 7d,... For example, 7a and 7b may be overlapped and connected by caulking of rivets 7r... Inserted through the mounting holes 7a and 7b, or as shown in FIG. The frame parts 3a…, 6
a may be connected to each other by screws 57. Therefore, while the frame 1 is assembled, the guide portion 2ax
And the elevation drive units 4a are already mounted on the respective frame parts 3a, 6a, so that their positioning is performed simultaneously.

Further, inside the frame 1, there is disposed a housing body mounting frame portion 11 whose peripheral portion is fixed to the support pieces 25 of the sliders 23 and the movable arms 32. The storage body mounting frame portion 11 is also integrally formed in a rectangular shape by combining a plurality of frame members 61 using an L-shaped square bar, and the storage body C shown in FIG. 5 is mounted thereon.

Therefore, it is possible to obtain the elevating device 10 including the highly rigid frame 1 and the storage body mounting frame portion 11 and secure sufficient mechanical strength, and the respective elevating drive portions 4a are reliably synchronized.

The lifting device 10 operates as follows. First, by the operation of the drive motor 52 in the drive frame 6a (same for the 6b side), the sector gear 39 rotates around the fixed support shaft 37, and the movable rail 32 is displaced upward. As a result, the storage body mounting frame portion 11 is elevated by being guided by the guide portions 2ax and 2ay. Thereby, the storage body C rises above the floor surface F through the opening S. On the other hand, if the drive motor 52 is operated in the reverse direction, the storage body C can be lowered to below the floor surface F shown in FIG.

The embodiments have been described in detail above, but the present invention is not limited to such embodiments. For example, although the example using the X-arm mechanism has been described, the present invention can be similarly applied to a mechanism using another principle such as a geared wire. In addition, details, configurations, shapes, materials, and the like can be arbitrarily changed without departing from the gist of the present invention.

[Effect of the invention]

Thus, according to the lifting device for the underfloor storage according to the present invention, a pair of guide frame portions in which the upper and lower two frame members are connected by the guide rails and at least four frame members are formed in a rectangular frame shape. And a pair of driving frame parts to which an elevating drive part for elevating and lowering the storage body is attached, and a guide frame part and a driving frame part are alternately connected by a connecting part to form a rectangular parallelepiped frame, Since the slider mounted movably on the guide rails and the storage body mounting frame portion supported by the lifting / lowering drive portion are arranged inside the frame, the following remarkable effects are obtained.

Since the four frame parts to which the guide rails and the elevating drive unit are mounted are assembled at the time of installation, accurate positioning can be performed at the same time as the assembling, so that time and labor for positioning are almost unnecessary.

Since the overall rigidity is dramatically increased, sufficient mechanical strength can be ensured, and the elevation speeds of the elevation drive units can be reliably synchronized.

Since it can be prepared for each frame unit including the storage unit mounting frame unit, it is extremely advantageous in terms of assembly, painting, transportation, storage and the like.
