 An embodiment of the present invention will be described below with reference to the drawings. 1 is a schematic perspective view showing an embodiment according to the present invention, and FIG. 2 is a sectional view taken along the line AA of FIG.

The sink 1 of this embodiment has a substantially rectangular sink part 2 having a water tank 6, and a storage base 3 supporting the sink part 2 and capable of storing kitchen utensils and the like therein. ing . The sink portion 2 is provided at the deepest portion of a water tank 6 in which a concave portion 5 for accumulating water is formed in a substantially central portion of an upper surface portion 4 formed of a stainless plate and the inclined bottom portion 6a of the water tank 6. It also has a drainage port 7 and a faucet 8 provided on the upper surface 4 near the water tank 6 and having a faucet facing the water tank 6. If a water splash prevention plate 9 made of a stainless steel plate or the like is provided on the outer periphery of the sink portion 2, water does not splash around the sink 1 during use, which is preferable for a so-called face-to-face sink. Become.

The storage base 3 is a wooden box-like shape having an opening and closing door 10 provided in the opening provided on the front side and the upper side of which is open. A step portion 12 is formed at the upper end portion 11a of the above, and the lower end portion 13a of the side wall 13 of the sink portion 2 is fitted therein, and both of them are recessed and fitted. As shown in FIG. 2, the range S of this concave-convex fitting is the lifting stroke of the sink portion 2 with respect to the storage base 3.

That is, in this embodiment, the sink portion 2 and the storage base 3 are configured to be vertically slidable with each other, and the upper end portion 11 a of the peripheral wall 11 of the storage base 3 serves as a guide to allow the sink portion to move. 2 is designed to move.

As the raising / lowering means 15 for raising / lowering the sink portion 2 in the height direction, for example, as shown in FIGS. Use is preferred. As shown in FIG. 3, each jack device 15a includes a rhomboidal link mechanism 16 and a push-up bar having one end erected on an upper piece 16a of the link mechanism 16 and the other end fixed to the lower surface of the sink portion 2. 17, a screw rod 18 with left and right reverse threads for opening and closing the link mechanism 16 in the vertical direction, and a handle connecting portion 18a having a quadrangular cross section formed at the end of the screw rod 18 are detachably fitted. And a lower piece 20 for fixing the link mechanism 16 to the bottom surface of the storage base 3. One handle 19 may be prepared for both the left and right handle connecting parts 18a, but preferably, a pair of handles are detachably fitted to the left and right handle connecting parts 18a. Preferably.

Even when the sink portion 2 is moved up and down by such a jack device 15a, the water supply pipe 21 communicating with the faucet 8 and the drainage water are drained so that the water supply / drainage function of the sink portion 2 is not impaired. It is preferable that the drainage pipe 22 connected to the port 7 is composed of a flexible pipe that is expandable and contractible, for example, a bellows pipe or a rubber pipe. When installing the water supply pipe 21 and the drainage pipe 22, it is preferable to allow a certain amount of allowance for the length of the sink unit 2 in consideration of the amount of vertical movement of the sink unit 2.

Next, the operation will be described.

When the user wants to change the height according to his / her own height or convenience, he / she operates the left and right jack devices 15 a, 15 a installed in the left and right corners of the storage table 3. First, the handles 19 are fitted into the handle connecting portions 18a at the ends of the left and right screw rods 18 of each jack device 15a, and both are rotated simultaneously. The rotation of the handle 19 causes the link mechanism 16 to open or close, and the push-up bar 17 provided upright on the upper piece 16a of the link mechanism 16 moves up or down. Since the upper end of the push-up bar 17 is fixed to the sink portion 2, the sink portion 2 is pushed up or pulled down as the push-up bar 17 is moved up or down, and the sink portion 2 is stored in the storage base 3 of the sink portion 2. The height adjustment is performed. In this case, since the side wall lower end portion 13a of the sink portion 2 is placed on the upper end portion 11a of the peripheral wall 11 excluding the front surface of the storage base 3, the sink portion 2 is left and right along the peripheral wall upper end portion 11a of the storage base 3. The heights are raised and lowered substantially in parallel without any difference, and the height with respect to the storage base 3 is smoothly adjusted. Even after the height is adjusted in this manner, the side wall lower end portion 13a of the sink portion 2 is in contact with the peripheral wall upper end portion 11a of the storage base 3, so that a lateral shift may occur. Absent. Further, in each jack device 15a, since the screw rod 18 is meshed with the piece body 23, the link mechanism 16 does not open and close, and the height position of the sink portion 2 with respect to the storage base 3 is surely secured. Will hold.

Therefore, if the handle 19 is removed at a position where the sink portion 2 is at the optimum height, the screw rod 18 of the jack device 15a does not rotate and the entire jack device 15a is fixed, and the sink portion 15a is fixed. 2 is fixed at the desired height. As a result, the user can use the sink as a height according to his / her preference or height, and can perform the work comfortably, safely and efficiently.

In the above-described embodiment, the jack device 15a is used as the elevating means for adjusting the height of the sink portion 2, but the present invention is not limited to this, and is within the scope of the utility model registration claim. Various modifications can be made. For example, as shown in FIG. 4, the end portion of the push-up bar 17 may be supported by a hydraulic / pneumatic cylinder 30 and moved up and down by hydraulic / pneumatic means, and as shown in FIG. A bellows tube 32 may be installed in the cylinder 31, and air may be sent to this by a bellows type pump 33 having a check valve (not shown) to raise and lower the sink portion 2. As a simpler method, as shown in FIG. 6, a pin 34 whose vertical position can be changed is provided on the upper end portion 11a of the peripheral wall of the storage base 3 at least on the peripheral walls facing each other, and the sink portion 2 is formed by this pin 34. It may be supported. In FIG. 6, reference numeral “35” is a hole into which the pin 34 is inserted.
