Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to furniture that is mounted at a high position, such as a hanging cabinet that is mounted on the upper wall of a sink.

2. Description of the Related Art Conventionally, furniture such as hanging cabinets that are installed at high places have already been equipped with a lifting function in order to improve their usability. A cabinet 3 is fixed with wood screws 2, and a movable shelf 5 is attached inside the cabinet 3 via a rail 4 so as to be slidable up and down. A wire 7 is fixed to the top surface 6 of the movable shelf 6, and the other end of the wire 7 is fixed to a winding device 8, so that it can be wound up and undone by a motor 9. The driving and stopping of the motor is controlled by a switch 10 provided on the front of the cabinet 3.

Problems to be Solved by the Invention Although the conventional hanging cabinets with the above-mentioned lifting and lowering functions are functionally satisfactory, they are expensive and cannot be used in general households. It has drawbacks such as being stiff and requiring a considerable amount of space to incorporate the winding device 8 and motor 9.

In addition, the movable shelf 5 is driven without using a motor.
There are some that are done manually, but in this case, the drawback is that the human power is weak and cannot lift heavy objects.

The present invention solves the above-mentioned conventional drawbacks, and aims to provide furniture with a lifting device that is inexpensive and capable of lifting and lowering heavy items.

Means for Solving the Problems In order to achieve the above object, the furniture with a lifting device of the present invention has the following features:
A movable body having a storage section is disposed inside the cabinet so as to be freely raised and lowered, and the rear lower end is rotatably supported on the cabinet, and a cam body having a push-up part formed on the upper part allows the movable body to be maintained horizontally. It is configured to be able to move up and down.

Function In the above configuration, the movable body is moved up and down by rotating the cam body, and high-cost parts such as a winding device and a motor are not used, so the cost is low.
Since it is lifted and lowered by a cam body that applies the principle of a lever, it has the effect of allowing heavy objects to be lifted and lowered even with human power.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 6, reference numeral 11 denotes a furniture cabinet, which is fixed to a wall surface 13 with wood screws 12. A movable body 16 is attached to the lower part 14 of the cabinet 11 via a sliding V-/L/16 so as to be vertically movable. A substantially U-shaped cam receiver 18 is fixed horizontally to both sides 17 of the movable body 16 with its opening facing downward. On the other hand, two substantially fan-shaped cam bodies 19 are disposed between the side of the movable body 16 and the inside of the cabinet 11, and the lower end of the cam body 19 is connected to the side of the gear vignette 11 via a pin 2o. The upper part of the cam body 19 is engaged with the substantially U-shaped inside of the cam receiver 18 so as to be slidable in the horizontal direction. Furthermore, the two cam bodies 19 include a flat front plate 21;
The L-shaped front bottom plate 22 and the flat guard plate 23 are connected to each other.

The operation of the above configuration will be explained below.

As shown in FIGS. 1, 2, and 3, when the front plate 21 is pulled in the direction of the arrow 24 from a state in which the front plate 21 is lowered, the cam body 19 rotates about the pin 20. and cam receiver 1
8 slides backward along the cam receiver 18, the cam receiver 18 and the movable body 16 are lifted upward, and when the cam body 19 has rotated approximately 90 degrees, the end portion is slid backward along the cam receiver 18. As shown in Figure 4, the movable body 16
4, and the front opening portion is closed by a front plate 21. At this time, since the contact point between the cam receiver 18 and the cam body 19 is located behind the perpendicular line passing through the center of the pin 2o,
The weight of the movable body 16 applies a force in the direction of the arrow 24 to the cam body 19, and the front plate 21 is pressed upward, thereby keeping the cam body 19 and the movable body 16 stopped.

Therefore, by operating the front plate 21, the movable body 1
When the movable body 16 is moved up and down and the movable body 16 is lowered, the front side is opened, so that the stored items 25 can be taken in and out.

As described above, this embodiment has the advantage of being able to be manufactured at low cost because it does not require a hoisting mechanism or a motor and has a simple component structure. In addition, the cam body 19 at the center of the elevating mechanism has a structure that applies the lever principle, so it can be operated with a weak force, and the direction in which force is applied is also the direction of pulling toward you, which improves operability. It has a good effect.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the following effects can be obtained.

(1) The mechanism is simple and costs are low because expensive parts such as motors are not used.

(2) Since the principle of lever is applied and the direction of operation is easy to apply force, it is possible to lift and lower heavy weights even with human power.
