Description

A sink capable of changing elevation

The present invention relates to a drainage basin, and more particularly, by a driving means while supporting a drainage basin such as a wall-mounted urinal or wash basin, the stopper stops at a desired position by the stopper means and automatically lifts when the stopper means are unlocked. The present invention relates to a height-adjustable drainage that allows the height of the drainage to be properly adjusted according to the user's convenience through the gas spring that is movable.

In general, the drainage basin, such as a urinal or wash basin, which is divided into a wall-mounted type and a self-supporting type, is installed with a fixed height, so that the user has to use it according to the height of the drainage regardless of his / her physical condition.

However, in using the wall-mounted drainage basin, the height of the user is different, and in the case of a child or a physically handicapped person, it is often impossible to use a toilet fixed to a certain height as described above. There was an inconvenience to use.

Therefore, in order to solve the above-mentioned problems, the wall-mounted drainage is supported on a frame and the like, and the frame is lifted along the guide member through the driving force of the driving motor to adjust the height of the drainage.

However, the wall-mounted drainage will generally have a weight of about 10 kgf. Therefore, when lifting a drain having a weight as described above through a general drive motor, the drive motor should have a torque greater than the weight of the drain. As a result, the size of the driving motor is increased, and the cost thereof is also increased.

Accordingly, an object of the present invention is to use a lifting means such as a gas spring which is lowered by the driving means while supporting the wall-mounted drainage basin, has an optional stop position through the stopper means, and enables the upward movement when the stopper means are unlocked. It is to provide a height-adjustable drainage that allows the height of the drainage to be properly adjusted.

To this end, according to the present invention, the elevating unit 110 is provided on both sides of the frame 102 for supporting the drainage main body 101 to move up and down; A driving unit 120 providing an external force to the frame 102 so that the lifting unit 110 moves up and down; A stopper unit 130 for positioning the drainage main body 101 at a height according to the elevation of the elevating unit 110 according to whether the driving unit 120 provides an external force; And it is provided a height adjustable drain including an input unit 140 and a power supply (not shown) for supplying a signal and power for the operation of the drive unit 120 and the stopper 130, respectively.

Here, the drain body main body 101 is preferably a urinal or a sink.

In addition, the elevating unit 110 extends from the piston rod 111 and the piston rod 111 fixedly installed at the lower end of the frame 102 supporting the drain body main body 101 and is the same as the inner diameter of the cylinder 112. It is preferably a gas spring or a pneumatic cylinder comprising a piston 113 having an area and a cylinder 112 for elevating the piston 113 in accordance with gas or hydraulic pressure.

In addition, the driving unit 120 is a wire bobbin 122 and a wire bobbin 122 connected to the other end of the wire 121 and the other end of the wire 121 connected to the lower end of the frame 102 to wind / reel the wire 121. It is preferable that the drive motor 123 for generating a driving force to rotate.

In addition, the drive motor 123 preferably has an output torque corresponding to an external force of a predetermined magnitude that is applied to or released from the weight of the body main body 101 so that the piston 113 of the elevating unit 110 is elevated. .

In addition, the drive unit 120 includes a rack gear (not shown) and a frame 102 installed in the longitudinal direction of the lifting unit 110 on the side wall of the housing 103 instead of the wire 121 and the wire bobbin 122. It is preferable to include a pinion gear (not shown) which is provided on the drive shaft of the drive motor 123 fixed to one side of the) moves along the rack gear.

In addition, the stopper part 130 may have irregularities of the first rack gear 131 and the first rack gear 131 attached to one side of the wire bobbin 122 that is rotated when the driving motor 123 is driven. Is connected to the second rack gear 132 and the second rack gear 132 through the shaft 133 to be slidably coupled to the first portion when the driving motor 123 is driven or when the operating power is supplied. Preferably, the rack gear 131 includes a solenoid 134 that engages or spaces the second rack gear 132.

Therefore, according to the above, by using a lifting means such as a gas spring, which is lowered by the driving means while supporting the wall-mounted drainage basin, has an optional stop position through the stopper means, and which allows the upward movement when the stopper means are unlocked. For example, the height of the sump can be adjusted appropriately.

In addition, a pair of lifting means is provided below the sump, so that the lifting means has a small cylinder output of about half the weight of the sump, so that the inner diameter of the gas spring that is a component of the lifting means can be designed small. As a result, installation and manufacturing costs can be reduced.

In addition, since the external force required to lower the sump is designed to be small, the torque output of the driving means can also be reduced, thereby enabling accurate control by using a relatively inexpensive small motor.

Further, by simultaneously operating or supplying the operating power to the driving means and the stopper means, the stopper means is operated in the stop state of the driving means and the stopper means is released in the driving state of the driving means, thereby elevating the lifting means when the driving means is stopped. The position of the sump can be prevented from being changed by the force F2 to be made so that the sump can be stably positioned at a desired height.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a height adjustable drain according to a preferred embodiment of the present invention, Figure 2 is an exploded cross-sectional view showing the drainage of Figure 1, Figure 3 is a lift in the drainage of Figure 2 Fig. 4 is an excerpt of the main part showing the steel part, and Fig. 4 is an excerpt of the main part showing the drive part and the stopper part in the drain in Fig. 2.

As shown in Figures 1 to 4, the height adjustable drain according to a preferred embodiment of the present invention, the lifting unit is provided on both sides of the frame 102 for supporting the drain body main body (101) 110, the driving unit 120 for providing an external force to the frame 102 so that the elevating unit 110 moves up and down, depending on whether or not the external force of the elevating unit 110 is provided, the drainage body at the height of the elevating unit 110 It includes a stopper 130 for positioning the 101 and the input unit 140 and a power supply (not shown) for supplying a signal and power for the operation of the drive unit 120 and the stopper 130, respectively.

Here, the frame 102, the elevating unit 110, the driving unit 120 and the stopper 130 is in appearance like a folding antenna according to the elevating operation of the elevating unit 110 in the lower side of the drain body main body (101) It is preferably provided inside the housing 103 that is folded and extended, and the input unit 140 and the power supply unit (not shown) are provided outside the housing 103.

The elevating unit 110 is located at the other end of the piston rod 111 and the piston rod 111, one end of which is fixed to both ends of the lower end of the frame 102 supporting the drain body main body 101, It is a pair of gas spring or pneumatic cylinder including a piston 113 having the same area as the inner diameter and the cylinder 112 for elevating the piston 113 in accordance with the gas or hydraulic pressure.

Here, the piston 113 and the cylinder 112 having the through hole 113a of the elevating unit 110, the piston 113 is moved up and down by the principle of Pascal, which will be described in detail as follows.

First, as shown in FIG. 3, the upper and lower surfaces of the piston 113 positioned inside the cylinder 112 are freely filled up and down the piston 113 by a through hole 113a formed in the piston 113. Since the back can be moved, the same pressure is generated respectively.

Here, when the pressure applied to the upper surface of the piston 113 is called P1 and the pressure applied to the lower surface of the piston 113 is called P2, P1 is a force for pressing the A1 to the area A1 of the upper surface of the piston 113. P2 is defined as having a value obtained by dividing F1 by dividing the force F2 for pressing A2 by the area A2 of the lower surface of the piston 113.

Moreover, since P1 and P2 which are pressures applied to the area A1 of the upper surface of the piston 113, and the area A2 of the lower surface are the same according to Pascal's principle, (F1 / A1) = (F2 / A2) is satisfied.

On the other hand, the area A1 of the upper surface of the piston 113 is reduced by the thickness of the piston rod 111 compared to the area A2 of the lower surface of the piston 113 has an area of about 0.8 times the A2.

Therefore, the force for raising the piston 113, that is, the force F2 for pressing the lower surface A2 of the piston 113 has a force of about 1.25 times the force F1 for pressing the upper surface A1 of the piston 113.

If this is expressed as an expression, it is as follows.

P1 = P2;

(F1 / A1) = (F2 / A2), where A1 = 0.8 * A2;

F2 = (A2 / A1) F1 = 1.25 * F1, where F1 is the weight of the sump body 101 and the frame 102

Therefore, the piston 113 because the force F2 for raising the piston 113 is 1.25 times larger than the force F1 (self-weight of the drainage main body 101 and the frame 102) for lowering the piston 113. In order to lower the F1 must have a force greater than F2.

For example, when the weight of the sump main body 101 and the frame 102 supporting the sump main body 101 is about 12 kgf, this becomes a force F1 for pressing the upper surface A1 of the piston 113. However, since the force F2 is greater than the force F1, the force 113 must be 15 kgf or more, in order for the piston 113 to descend, which is greater than the force F2.

Here, since the force F1 is 12 kgf of the weight of the drain body main body 101 and the frame 102, the piston 113 continuously lowers when only an external force of 3 kgf or more is continuously applied to the 12 kgf. When the external force of 3 kgf or more is not continuously applied, the piston 113 is continuously raised by the force F2.

On the other hand, since the lifting unit 110 is composed of a pair of gas springs or hydraulic cylinders provided on both sides of the frame 102, each of the gas spring or hydraulic cylinders are the drainage main body 101 and the frame 102 Having a small cylinder output of about 6 kgf, which is about half of its own weight, the drainage main body 101 can be raised and the inner diameter of the cylinder 112 of the gas spring or hydraulic cylinder corresponding to the cylinder output can be reduced. The manufacturing cost according to the configuration of the elevating unit 110 can be reduced.

In addition, a pair of elevating portions 110 are provided on both sides of the drainage main body 101 to stably support the drainage main body 101, thereby increasing the drainage main body 101 of the drainage main body 101. It is possible to prevent the phenomenon caused by weight and vibration caused by the weight.

As shown in FIG. 4, the driving unit 120 is a wire 121 having one end connected to the center lower end of the frame 102 and a wire connected to the other end of the wire 121 to wind / reel the wire 121. The bobbin 122 and the wire bobbin 122 includes a driving motor for generating a driving force to rotate.

Here, the driving motor 123 is a means for applying a constant external force to the force F1 for lowering the piston 113 in order to lower the piston 113 of the elevating unit 110.

In other words, an external force of a predetermined size, for example, a force of about 3 kgf or more must be applied to allow the drainage main body 101 and the frame 102 to be lowered by the elevating portion 110. The external force required for descent is about 4 kgf.

Here, the drive motor 123 preferably has a torque output corresponding to the external force of about 4 kgf, the force of about 4 kgf is a small force, it may be composed of a small motor such as a stepping motor. In addition, this can save the cost of the drive motor 123 and can reduce the generation of noise.

On the other hand, the drive unit 120, instead of the wire 121 and the wire bobbin 122, a rack gear (not shown) in the longitudinal direction of the elevating unit 110 on the side wall of the housing 103, the frame ( The drive motor 123 may be fixed to one side of the 102 to allow the pinion gear (not shown) provided on the drive shaft of the drive motor 123 to be engaged with the rack gear.

As shown in FIG. 4, the stopper 130 may include a first rack gear 131 and a first rack gear attached to one side of the wire bobbin 122 that is rotated when the driving motor 123 is driven. It is connected to the second rack gear 132 and the second rack gear 132 slidably engaged with the uneven portion of the 131 through the shaft 133 to drive or drive power of the drive motor 123 It includes a solenoid 134 so that the second rack gear 132 is engaged or spaced in the first rack gear 131 at the time of supply.

Here, when operating power is applied to the solenoid 134 in a state where the first rack gear 131 and the second rack gear 132 are engaged, the shaft 133 of the solenoid 134 is solenoid by electromagnetic force. The second rack gear 132 connected to the shaft 133 of the solenoid 134 is spaced apart from the first rack gear 131 by moving to the right side (+ X direction) of the central axis of 134.

In addition, when the operating power is cut off from the solenoid 134 in the state where the first rack gear 131 and the second rack gear 132 are free, the shaft 133 of the solenoid 134 is caused by electromagnetic force. The second rack gear 132 connected to the shaft 133 of the solenoid 134 is engaged with the first rack gear 131 by moving to the left (-X direction) of the central axis of the solenoid 134. .

In addition, the shaft 133 of the solenoid 134 is a second rack in which the drive motor 123 slips due to excessive load generated in the drive motor 123 and meshes with the first rack gear 131. It is preferable that the size control unit 132 is connected to and supported by an anti-rotation means (not shown) inside the solenoid 134.

Therefore, according to the stopper 130, when the rotation of the driving motor 123 is stopped during the lifting operation of the piston 113 by the driving motor 123, the lifting operation of the piston 113 is stopped and the wire bobbin 122 of the wire bobbin 122 is stopped. The first rack gear 131 and the second rack gear 132 of the solenoid 134 are engaged to prevent the piston 113 from elevating by the force F2 and the drain body 101 to a desired height. It can be positioned stably.

Hereinafter, the operation and the effect of the height can be adjusted according to a preferred embodiment of the present invention having the above configuration will be described.

First, the process of lowering the height of the drain according to the preferred embodiment of the present invention will be described.

First, when an input button corresponding to the lowering of the drain body main body 101 is pressed through the input unit 140 provided at one side of the housing 103, the driving motor 123 of the driving unit 120 rotates. Accordingly, the wire bobbin 122 is rotated.

Here, when the input button is pressed by the power supplied to the solenoid 134 connected to the first rack gear 131 and the second rack gear 132 meshed with the first rack gear 131. The engagement between the first rack gear 131 and the second rack gear 132 is released, the wire bobbin 122 is rotatable.

Thereafter, the wire 121 connected to the frame 102 supporting the drainage main body 101 is wound on the wire bobbin 122 and accordingly, the piston of the lifting unit 110 provided on both sides of the frame 102 ( 113) goes down.

Here, since the driving motor 123 applies a constant external force such that the force F1 for lowering the piston 123 is greater than the force F2 for raising the piston 123, the piston 113 is lowered and drained accordingly. The main body 101 is lowered.

Subsequently, when the input button for the lowering is released in order to stop the drainage main body 101 in a lowering operation as described above, the rotation of the driving motor 123 of the driving unit 120 is stopped and accordingly. Rotation of the wire bobbin 122 is also stopped.

Here, when the input button is released, the power supplied to the solenoid 134 is cut off, and thus the second rack gear 132 is engaged with the first rack gear 131 so that the drain body main body 101 is engaged. ) Is stably positioned in place without being raised by the force F2 for raising the piston 113.

On the other hand, the process of increasing the height of the drain according to a preferred embodiment of the present invention will be described.

First, when the input button corresponding to the rise of the drain body main body 101 is pressed through the input unit 140 provided at one side of the housing 103, the driving motor 123 of the driving unit 120 is reversed. .

Here, when the input button is pressed, the solenoid 134 connected to the first rack gear 131 provided on the wire bobbin 122 and the second rack gear 132 meshed with the first rack gear 131. The engagement between the first rack gear 131 and the second rack gear 132 is released by the power supplied to the wire bobbin 122 is capable of reverse rotation.

Thereafter, the wire 121 connected to the frame 102 supporting the drainage main body 101 is recommended from the wire bobbin 122 and accordingly, the piston of the lifting unit 110 provided on both sides of the frame 102 ( 113) rises.

Here, since the external force applied to the force F1 for lowering the piston 113 is released as the driving motor 123 reverses, the piston 113 is forced by the force F2 for raising the piston 113. Ascends and the drainage body 101 rises accordingly.

Subsequently, when the input button for the lift is released to stop the drainage main body 101 in a rising operation as described above, the driving motor 123 reverse rotation of the driving unit 110 is stopped and thus Accordingly, the reverse rotation of the wire bobbin 122 is also stopped.

Here, when the input button is released, the power supplied to the solenoid 134 is cut off, and thus the second rack gear 132 is engaged with the first rack gear 131 so that the drain body main body 101 is engaged. ) Is no longer raised by the force F2 for raising the piston 113 and is stably positioned in place.
