Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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.

PRIOR TECHNOLOGY Conventionally, furniture such as hanging cabinets that are installed at high places already have a lifting function for the purpose of improving their usability, but their configuration is as shown in Figure 7. Cabinet 3 with wood screw 2
A movable shelf 5 is attached to the inside of 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 5, and the other end of the wire 7 is
It is fixed to an upper winding device 8, and 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 The conventional hanging shelf with the above-mentioned lifting and lowering function is functionally satisfactory, but its high cost makes it difficult to make it a product that can be used in general households. There are other drawbacks such as a considerable amount of space being required to incorporate the winding device 8 and the motor 9.

In addition, the movable shelf 5 may be driven manually without using a motor, but in this case, there is a drawback that heavy objects cannot be lifted because the human power is weak.

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 objects.

Means for Solving the Problems In order to achieve the above object, the furniture with an elevating device of the present invention includes a movable body that is disposed so as to be movable up and down in a cabinet whose bottom and front sides are open, and whose lower end is rotated around the cabinet. The movable body is movable up and down while being maintained horizontally by a cam body which is movably pivoted and has a push-up part formed at its upper end. It is configured to be fixed to the body.

Function In the above configuration, the elevating body moves up and down by rotating the cam body, and the opening of the elevating body opens and closes, and raising and lowering the movable body requires expensive winding devices, motors, etc. Since no parts are used, the cost is low, and since it is lifted and lowered by a cam body that applies the principle of levers, heavy objects can be lifted and lowered by hand. In addition, since the front plate of the cabinet opens and closes as the cam body is operated,
The front opening area is wide, making it easy to take in and take out stored items.

Embodiment Hereinafter, an 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 rail 15 so as to be vertically movable. Both outer surfaces 17 of the movable body 16
A substantially U-shaped cam receiver 18 is fixed horizontally to the cam receiver 18 with its opening facing downward. On the other hand, two approximately fan-shaped cam bodies 19 are arranged between the inside of the lower part of the cabinet 11 and both outsides of the movable body 16, and the rear lower end of the cam body 19 (see FIG. 4) is connected to the pin 2.
The upper part of the cam body 19 is rotatably supported on the cabinet 11 via the cam receiver 18.
It is designed to be guided by being internally engaged in a substantially U-shape. The two cam bodies 19 include a flat front plate 21, an L-shaped bottom plate 22, and a flat guard plate 23.
It has a connected structure.

The operation of the above configuration will be explained below. As shown in FIGS. 1 to 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 around the pin 20, and the cam body 19 rotates around the pin 20. The end that engaged with the cam receiver 18
At the same time, the cam receiver 18 and the movable body 16 are lifted upward, and the cam body 1
When 9 has rotated approximately 90 degrees, Figs. 4 and 5
As shown in the figure, the movable body 16 is housed in the lower part 14 of the cabinet, and the front opening is closed by the front plate 21. At this time, the cam receiver 18 and the cam body 1
By positioning the contact point 9 behind the perpendicular line passing through the center of the pin 20, due to the weight of the movable body 16,
A force in the direction of arrow 24 is applied to the cam body 19,
By pressing the front plate 21 upward, the cam body 19 and the movable body 16 are kept stopped. Therefore, by operating the front plate 21, the movable body 16 is raised and lowered, and when the movable body 16 is lowered, the opening is wide enough to accommodate the lowering of the movable body and the opening of the front plate. This allows the stored items 25 to be taken in and out easily.

As described above, according to this embodiment, since it has a simple component structure without using a hoisting mechanism or a motor, it can be manufactured at low cost. Also,
The cam body 19, which is 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, so it is said to be easy to operate. have an effect. Furthermore, since the front plate 21 opens and closes in accordance with the operation of the cam body 19, the front opening area is wide and there is an effect that it is easy to take in and take out stored items.

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 no expensive parts such as motors are used.

(2) By applying the lever principle and operating in a direction that makes it easy to apply force, it is possible to lift and lower heavy weights even though it is done by hand.

(3) Since the front plate opens and closes as the cam body is operated, the front opening area is wide, making it easy to take in and take out stored items.
