The wall mounting frame 3 is a rectangular frame as viewed from the front, and has a vertically extending middle sliding frame guide groove on both left and right sides thereof.
It has guide cabinet grooves 11 and 11 and cabinets 10 and 10. Further, the lower end portions of the gas springs 6, 6 are fixed near the lower side. Here, the gas spring 6 is slidably inserted into the cylinder portion 30 in which the high-pressure gas is sealed and slidably inserted into the cylinder portion 30 so as to be pressed outward (extended) by the pressure of the high-pressure gas. And a slide bar 31 that is The middle slide frame 4 includes a horizontally long rectangular plate 12,
Rollers 13 are rotatably mounted on four corners of the rectangular plate 12 around the horizontal axis in the front-rear direction. The upper ends of the gas springs 6, 6 are fixed to the rectangular plate 12. .
The rollers 13 are rotatably brought into contact with the slide frame guide grooves 10 in the wall mounting frame 3.

The cabinet 5 is provided with two windows 14 and 14.
Frame body 15 having a rectangular shape in front view and an inverted gate shape in plan view
And rollers 16 rotatably mounted on the upper and lower portions of the left and right walls of the frame body 15 so as to be rotatable about a horizontal axis in the left-right direction.
And the cabinet 2 is fixed to the frame body 15 with screws or the like. The rollers 16 are rotatably inserted into the cupboard mounting frame guide grooves 11 of the wall mounting frame 3.

As shown in FIGS. 4 and 5, the pulley 8 is formed by a double groove comprising a first winding portion 17 having a uniform radius A and a second winding portion 18 having a variable radius B. Structure. Specifically, the first winding portion 17 and the second winding portion 18 are formed integrally so as to overlap in the axial direction, and the second winding portion 18 is indicated by an arrow E in FIG. The radius B is configured to gradually decrease over a range where the central angle is slightly smaller than 360 ° in the circumferential direction.

Further (returning to FIGS. 1, 2 and 3),
A first striated body 19 having one end wound around the first winding portion 17 and the other end fixed to the wall mounting frame 3;
A second striated body 20 having one end wound in the opposite direction around the second winding portion 18 and the other end fixed to the cabinet 5 for extending the gas spring 6. The push-up force compensating means 21 is configured to keep the push-up force acting on the cabinet 2 substantially constant in response to the accompanying decrease in the push-up force. First striatum
The other end of 19 is fixed to a projection 22 fixed near the lower side of the wall mounting frame 3, and the other end of the second linear body 20 is
Is fixed to a protrusion 23 fixed near the lower side. The lifting-type hanging cabinet 1 has a pushing-up force compensating means 21 for maintaining the pushing-up force acting on the cabinet 2 substantially constant in response to the attenuation of the pushing force caused by the extension of the gas springs 6, 6.

The push-up force compensating means 21 will be described in detail. As shown in FIG. 1, in a state where the cabinet 5 is lowered, the contact point where the second filament 20 contacts the second winding portion 18 is shown. The distance K between P and the rotation center axis L becomes the maximum, and as shown by the arrow H, the pulley 8 rotates in the direction of the arrow G as the cabinet 5 is raised, and the distance K gradually decreases. As shown in FIG. 2, when the cabinet 5 is completely raised, the distance K
Is minimized. In addition, the second winding unit of the pulley 8 is controlled so that the pushing force transmitted to the cabinet 5 is substantially constant.
The radius B of 18 is changed.

Now, the operation of the lifting cabinet will be described. As shown in FIGS. 1 and 2, the forces F, F of the gas springs 6, 6, which push the middle slide frame 4 upward, are reduced by the pulley 8, The force is transmitted to the cabinet 5 through the second striated body 20 as a lifting force (a pulling force I transmitted by the second striated body 20). Here, the forces F, F of the gas springs 6, 6 pushing the middle slide frame 4 upward gradually decrease from the contracted state in FIG. 1 to the extended state in FIG. However, from the shortened state (down state) of FIG. 1 to the extended state (up state) of FIG. 2, the pulley 8 rotates in the direction of the arrow G, and the distance K between the contact point P and the rotation center axis L is reduced. The push-up force transmitted to the cabinet 5 is kept substantially constant.

Accordingly, a substantially constant push-up force is applied to the cabinet 2 over the entire vertical range from the lowered state in FIG. 6 to the raised state in FIG. The lifting force (the pulling force I by the second striated body 20) is substantially equal to the load J of the cabinet 2. Thereby, the cabinet body 2 can be stably stopped in either the lowered state or the raised state. In addition, the force for raising and lowering the cabinet 2 with human hands can be extremely low.

Next, FIGS. 8, 9 and 10 show another embodiment of the liftable hanging cabinet according to the present invention, in which the weight of the mounted object is balanced with the weight of the mounted object placed on the cabinet 2. It has balancing means 24. The mounted object weight balance means 24 has first and second arm portions 26 and 27 which are pivotally mounted around a fixed axis M and extend in two different directions about the fixed axis M. A moving arm 25 and a coil spring 28 for imparting a swinging power are provided.

An arm length varying long hole 29 is formed in the first arm portion 26 of the swing arm 25, and a push-up force transmitting pin 32 fixed to the middle slide frame 4 is inserted into the long hole 29. Slide freely through. Further, the coil spring 28 applies a swinging force in the direction of pushing up the push-up force transmission pin 32 to the swing arm 25, and the push-up force transmission pin 32 is fixed as the push-up force transmission pin 32 is pushed up. It is configured to approach the axis M.

The first arm portion 26 is formed in an arc shape in which the tip warps upward in the ascending state of FIG. 9, and the arm length variable elongated hole 29 has the same arc shape. In addition, push-up force transmission pin 32
Is formed integrally with the support shaft 7 of the pulley 8. In addition, the mounted object weight balance means 24 has an initial elastic force setting adjustment mechanism 33 that can adjust the initial elastic force of the coil spring 28.

The initial elastic force setting and adjusting mechanism 33 is pivotally attached to the wall mounting frame 3 about the horizontal axis N in the front-rear direction so as to be swingable, and one end receives the tensile force of the coil spring 28. An arm-shaped swing member 36 configured as described above, is attached to the lower side of the wall mounting frame 3 so as to be able to advance and retreat in the vertical direction, and abuts against the lower surface of the other end of the swing member 36 to swing the swing member. And an adjusting screw 37 that can adjust the swing angle of 36.

More specifically, the lower end of a wire 35 such as a wire is connected to one end of the swing member 36, and the upper end of the wire 35 is connected to the lower end of the coil spring 28. Further, the lower end of a striated body 34 such as a wire is connected to the upper end of the coil spring 28, and the upper end of the striated body 34 is connected to the second arm portion of the swing arm 25.
Connect to 27 tips. Other configurations are the same as those described with reference to FIGS.

With the above configuration, the tensile force S of the coil spring 28 is transmitted to the push-up force transmitting pin 32 via the swing arm 25 as the force T for pushing upward. The force T is set equal to the weight of the object. In the raised state shown in FIG. 9, the swing arm 25 is in a sideways position, the distance Q between the push-up force transmitting pin 32 and the fixed shaft center M is minimized, and the coil spring 28 is slightly contracted. The force S is at a minimum. In the descending state of FIG. 10, the swing arm 25 is in a nearly vertical state, the push-up force transmitting pin 32 is at the position farthest from the fixed axis M, and the coil spring 28 is in the most extended state, so that the tension is increased. The force S becomes maximum.

As described above, in the ascending state, the distance Q is minimum (the arm length is minimum) and the tensile force S of the coil spring 28 is minimum. In the descending state, the distance Q is maximum (the arm length is maximum). At the same time, the tensile force S of the coil spring 28 becomes maximum, so that the upward pushing force T is substantially constant. That is, if the tensile force S is constant, the distance T between the fixed axis M and the connection point at the upper end of the striatum 34 is constant, and the force T is substantially inversely proportional to the distance Q. That is, as the cabinet 2 rises, the distance Q decreases and the force T increases. However, in the lifting-type hanging cabinet according to the present invention, the tensile force S increases as the cabinet 2 rises, and the force T is maintained substantially constant.

Accordingly, a substantially constant push-up force is applied to the cabinet 2 on which objects such as books, documents, and small articles are placed over the entire vertical range from the lowering state in FIG. 10 to the ascending state in FIG. Thus, the cabinet 2 can be stably stopped in both the descending state and the ascending state, and can be moved up and down with a light force by a person.

Further, by adjusting the adjusting screw 37 of the initial elastic force setting adjusting mechanism 33, the initial elastic force of the coil spring 28 (the elastic force in the lowered state in FIG. 9) can be adjusted. . Specifically, by screwing the screw 37 upward, one end of the swinging member 36 is lowered, so that the initial elastic force can be increased. Conversely, by screwing down the screw 37, the one end side of the swing member 36 rises, and the initial elastic force can be reduced. Therefore, it is possible to correspond to the weight of the mounted object.
