Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture that is mounted at a high position such as a hanging cabinet attached to an upper wall of a sink.

2. Description of the Related Art Conventionally, furniture such as hanging cabinets installed in high places has already been provided with a lifting function for the purpose of improving its usability, but its structure is as shown in FIG. The cabinet 3 is fixed with wood screws 2, and a movable shelf 5 is slidably mounted inside the cabinet 3 via rails 4. A wire 7 is fixed to the top surface portion 6 of the movable shelf 5, and the other end of the wire 7 is fixed to a winding device 8 so that a motor 9 can wind and unwind it. Driving and stopping of the motor are controlled by a switch 10 provided on the front surface of the cabinet 3.

Problems to be Solved by the Invention In the conventional hanging cabinet having the lifting function of the above-mentioned configuration, although the performance is almost satisfactory functionally, the cost is high and it is difficult to be a product that can be used in general households. In addition, there is a drawback that a considerable space is required for incorporating the winding device 8 and the motor 9.

In addition, the drive of the movable shelf 5 does not use a motor,
Although it is performed manually, in this case, there is a drawback in that a heavy object cannot be lifted because the human power is weak.

The present invention solves the above-mentioned conventional drawbacks, and an object of the present invention is to provide a furniture with a lifting device, which is low in cost and capable of lifting a heavy object.

Means for Solving the Problems In order to achieve the above object, in the furniture with a lifting device of the present invention, a movable body having a storage part is arranged in a cabinet so as to be able to move up and down, and a rear lower end of the furniture is rotatably mounted in the cabinet. Pivotally
A movable body is vertically movable by a cam body having a push-up portion formed on the upper portion thereof, and the contact point between the push-up portion and a cam receiver fixed to the movable body when pushing up the cam body. Is located rearward of a perpendicular line passing through the pivotal support of the cam body.

Action In the above configuration, the movable body is lifted and lowered by rotating the cam body, which is low cost because expensive components such as the winding device and the motor are not used, and the lever principle is applied. Since the cam body moves up and down, there is an effect that a heavy object can be moved up and down even by human power.
Further, when the movable body is housed in the cabinet, the movable body is stopped and maintained by its own weight because the contact point between the cam body and the cam receiver is located behind the perpendicular line passing through the pivotal support portion of the cam body. Therefore, there is no need for a complicated stopper mechanism, and there is an effect that the object can be achieved at low cost.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 7, 11 is a furniture cabinet,
It is fixed to the wall surface 13 with wood screws 12. A movable body 1 is attached to the lower portion 14 of the cabinet via a slide rail 15.
6 is attached so as to be vertically movable. A substantially U-shaped cam receiver 18 is horizontally fixed to both outer side surfaces 17 of the movable body 16 with its opening facing downward. On the other hand, two substantially fan-shaped cam bodies 19 are provided between the side portion of the movable body 16 and the inside of the cabinet 11, and the lower end portion of the rear portion is rotated to the side portion of the cabinet 11 via a pin 20. It is rotatably supported, and the push-up portion 19a of the cam body 19 is slidably engaged in the U-shaped interior of the cam receiver 18 in the horizontal direction. Further, when the movable body 16 is housed in the cabinet 11, the contact point between the push-up portion 19a of the cam body 19 and the cam receiver 18 is positioned behind the perpendicular line passing through the pin 20. Further, the two cam bodies 19 are composed of a flat plate-like 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 described below. Figure 1,
As shown in FIGS. 2 and 3, when the front plate 21 is lowered downward and the front plate 21 is pulled in the direction of the arrow 24, the cam body 19 rotates about the pin 20 to move the cam receiving member. The push-up portion 19a engaged with 18 slides rearward along the cam receiver, and the cam receiver 18 and the movable body 16 are lifted upward, and when the cam body 19 rotates about 90 degrees, Four
As shown in FIGS. 5 and 5, the movable body 16 is housed in the lower portion 14 of the cabinet, and the front opening is closed by the front plate 21. At this time, as shown in FIG.
8 and the contact point of the push-up portion 19a of the cam body 19 are located behind the perpendicular line passing through the center of the pin 20, so that the movable body 16
A force in the direction of arrow 24 is applied to the cam body 19 due to the weight of, and the front plate 21 is pressed upward, so that the cam body 19 and the movable body 16 are stopped and maintained. Therefore, by operating the front plate 21, the movable body 16 moves up and down, and when the movable body 16 is lowered, the front surface is opened, so that the stored item 25 can be put in and taken out.

As described above, according to the present embodiment, since a simple component structure is used without using a hoisting mechanism, a motor, or a complicated stopper mechanism, there is an effect that it can be manufactured at low cost. Further, the cam body 19, which is the center of the lifting mechanism,
Since it is a structure that applies the lever principle, it can be operated with a weak force, and since the direction of applying a force is also in the direction of pulling to the front, it has the effect of good operability. In addition, since there is no need to perform a special operation for locking and unlocking the stopper, there is an effect that it is easy to use.

EFFECTS OF THE INVENTION As is apparent from the above description of the embodiments, according to the present invention, the following effects can be obtained.

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

(2) The lever principle is applied and the operation direction is such that it is easy to apply force, so it is possible to lift and lower a heavy weight regardless of human power.

(3) Good operability because no special operation is required to lock or unlock the stopper.
