Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an emergency device for an underfloor storage for manual operation when an abnormality such as a failure occurs.

[Prior art and problems]

2. Description of the Related Art Conventionally, an underfloor storage is known in which an opening-and-closing type lid is attached to an opening provided on the floor of a kitchen so that an item can be stored in a storage case installed below the opening. In addition, in order to increase the storage volume, multiple connected storage cases are slidably loaded on rails attached along the floor so that each storage case can be selectively used. Has also been put to practical use.

By the way, since the conventional multiple-type underfloor storage is of a manual type, a user such as a housewife needs to slide the storage case located below the floor by hand, which makes it difficult to operate. In addition, when heavy items such as bottles are stored in the storage case, the total weight becomes extremely large, which is a great labor for housewives who use them in a complicated manner. Further, since the storage case slides across the opening on the floor, there is a risk that the hand is easily caught between the storage case and the opening during the sliding operation.

In order to solve these problems, a drive mechanism section using a drive motor may be arranged and the storage case may be moved by power, but since the drive mechanism section is installed on the lower surface of the floor,
When an abnormality such as a power failure or a failure occurs, it is practically impossible to use an emergency mechanism that is manually operated, and there is a problem to be solved that it is not easy to power this kind of underfloor storage.

An object of the present invention is to provide an emergency device for an underfloor storage that solves the problems existing in the prior art.

Further, a pair of left and right parallel rails 21a and 21b are arranged along the floor F on the floor constituents located on the left and right sides sandwiching the opening S, and a pair of rails 21a ... The support frames Ex and Ey of are movably loaded. Then, the storage cases Cx, Cy are inserted into the inside of each of the support frames Ex, Ey from above, and the locking edges bent and formed at the upper ends of the storage cases Cx are locked to the support frames Ex.

On the other hand, the guide rails 24a and 24b are attached to the floor component located diagonally above the rails 21a in parallel with the rails 21a. Each of the guide rails 21a ... Is formed in a C-shaped cross section, and sliders 25a, 25b slidable along the guide rails 24a. Also, the slider
25a ... And the support frame Ex are connected by connecting tools 26a and 26b. Furthermore, the slider 25a ...
Connect one ends of a and 7b respectively. Geared Wire 7a ...
Are arranged along the guide rails 24a, and the other end is led out from the guide rails 24a and connected to the drive mechanism 2 side. The drive mechanism unit 2 includes a drive motor 6 and a transmission gear mechanism that transmits the rotation of the drive motor 6 to the geared wires 7a.
Consists of 10. Further, the transmission gear mechanism 10 incorporates the emergency mechanism 3.

Next, the transmission gear mechanism 10 will be described in detail with reference to FIGS. 1 to 6.

First, reference numeral 31 is a gear case having a bearing portion 32 provided at the center thereof, which is supported by a base plate 33 and fixed to the lower surface of the floor F. On the other hand, a pinion shaft 35 is rotatably provided inside the bearing portion 32 via a collar 34. A pinion 36 is integrally provided at one end of the pinion shaft 35, and the pair of geared wires 7a and 7b are engaged with each other at 180 ° opposite positions of the pinion 36.

A worm wheel 9 is rotatably provided on the outer peripheral portion of the bearing portion 32. A worm gear 8 attached to the shaft of the drive motor 6 meshes with the worm wheel 9.
The worm wheel 9 and the collar 34 are pinion shafts.
It is held by a C ring 35a locked to 35. On the other hand, a clutch plate 38 having a non-circular cross section is fitted on the other side of the pinion shaft 35. An insertion hole 39 having the same shape as the cross-sectional shape of the pinion shaft 35 is formed in the center of the clutch plate 38. As a result, the rotation of the clutch plate 38 is restricted with respect to the pinion shaft 35,
And it can be displaced in the axial direction. Also clutch plate
A locking piece 40 that protrudes toward the worm wheel 9 is integrally formed on the 38, and a locking hole 41 that the locking piece 40 is inserted and locked is formed in the worm wheel 9. On the other hand, a stopper plate 42 is fixed to the other end of the pinion shaft 35, and a coil spring 43 is contracted between the stopper plate 42 and the clutch plate 38.

On the other hand, the operating portion 4 for attaching and detaching the jig T is attached to the clutch plate 38. The operation unit 4 includes a mounting plate 44 screwed to the clutch plate 38 and a mounting / dismounting nut 45 fixed to the mounting plate 44.
Has a screw hole portion 46. Further, the operation portion 4, that is, the opening of the screw hole portion 46 is arranged toward the lower surface of the floor F.

On the other hand, the floor F is formed with the insertion hole 5 that faces the screw hole 46.

Moreover, a cap 11 for closing the insertion hole 5 is prepared.
The cap 11 is a flat umbrella portion 11a whose outer peripheral side is gradually thinned.
And a cylindrical portion 11b provided at a right angle from the center of the lower surface of the umbrella portion 11a and having a length substantially the same as the thickness of the floor F, and a locking portion 11c formed at the tip of the cylindrical portion 11b so as to project slightly outward. , Is integrally formed of, for example, synthetic resin.

Next, the function of the emergency device 1 according to the present invention will be described.

First, in a normal state, as shown in FIG. 1, the tubular portion 11b of the cap 11 is inserted into the insertion hole portion 5 from above the floor F, and the insertion hole portion 5 is closed. At this time, the locking portion 11c is locked to the lower surface of the floor F and is prevented from coming off. Further, the umbrella portion 11a substantially coincides with the upper surface of the floor F. On the other hand, the clutch plate 38 in the emergency mechanism 3 is biased toward the worm wheel 9 side by the coil spring 43, and the locking pieces 40 ...
The worm wheel 9 and the pinion shaft 35 are connected via a clutch plate 38. Therefore, the rotation of the worm gear 8 is transmitted to the pinion shaft 35.

On the other hand, when an abnormality such as a power failure or failure occurs, the cap 11 is pulled out from the insertion hole 5 as shown in FIG.
A jig T having a threaded portion Ts at its tip is inserted into the insertion hole 5 from above the floor F, and the threaded portion Ts is completely screwed into the removable nut 45. Then, when the jig T is pulled against the elasticity of the coil spring 43, the clutch plate 38 is pulled to the worm wheel 9.
Can be separated from (see the phantom line in FIG. 5). As a result, the locking pieces 40 come out of the locking holes 41, and the pinion shaft 35 can be manually rotated by rotating the jig T.

Although the jig T and the operating portion 4 are illustrated as detachable structures using screws, other than that, a pin protruding laterally is provided at the tip of the jig T and the inner circumference of the hole provided on the operating portion 4 side is provided. A detachable structure may be used in which a T-shaped groove for locking the pin is provided on the surface and the structure of the locking relationship is used.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments. For example, the drive mechanism unit can adopt any other structure capable of moving the slider back and forth. Further, a part of the floor may be hollowed out, the hollowed out space may be used as an insertion hole, and the hollowed out part may be attached to the insertion hole via a hinge to form a cap. In addition, the detailed configuration, shape, and the like can be arbitrarily changed without departing from the scope of the present invention.
