DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
In this description, the front means the lower side of FIG. 1, the rear means the upper side of the figure, the left means the left side of FIG. 1, and the right means the right side of the figure.
[0007]
The storage 1 (a sink in this embodiment) has a storage main body 2 with an open upper surface, the inside of which is an article storage space 3, and an upper surface provided on the upper portion of the storage main body 2 as a work surface 5. And a top plate 7 having a water tank 6 provided at an edge of an opening penetrating in the vertical direction.
[0008]
An article storage space 3 on the right side of the storage body 2 is defined by a side wall 9 and a partition wall 10. A pair of left and right guide members 12 are provided on the upper surfaces of the side walls 9 and the partition wall 10 (side walls in claim 1) that face each other.
The guide member 12 includes a fixed rail 13 whose longitudinal direction is fixed to the partition wall 10 or the side wall 9 in the front-rear direction, and an intermediate direction in which the longitudinal direction provided on the fixed rail 13 is movable in the front-rear direction. The rail 14 and a movable rail 15 having a longitudinal direction provided in the intermediate rail 14 so as to be movable back and forth are oriented in the front-rear direction.
[0009]
Each of the movable rails 15 is provided with a pair of left and right lifting link devices 16. The right elevating link device 16 is a mirror placed with the mirror surface facing left in the center in the left-right direction between the left and right movable rails 15 and has the same shape as the image that appears when the left elevating link device 16 is projected. Therefore, only the left lifting link device 16 will be described in detail below.
As shown in FIGS. 2 to 6, the lift link device 16 has a base material 17 fixed to the movable rail 15. The left-side base material 17 and the right-side base material 17 constitute a back-and-forth motion member according to claim 1. A bi-foldable link mechanism 19 is pivotally attached to the front and rear portions of the base material 17 via a pivot 18 whose axis is directed in the left-right direction. The link mechanism 19 has a lower link piece 20 and an upper link piece 21 that are foldable in two via a connecting pin 22 whose axis is directed in the left-right direction. The lower link piece 20 and the upper link piece 21 are in a straight line state as shown in FIG. 2, and are bent in the direction of the arrow L in FIG. It is designed to be in close contact. The lower link piece 20 and the upper link piece 21 have a U-shaped cross section as shown in FIG.
[0010]
As shown in FIGS. 3 and 4, the front and rear lower link pieces 20 are pivotally connected to each other by a connecting plate 25 via a pivot 24 whose axis is directed in the left-right direction. With such a configuration, the base material 17, the front and rear lower link pieces 20, and the connecting plate 25 constitute a parallel crank mechanism. A long hole 26 that is long in the vertical direction is formed in the front and rear portions of the connecting plate 25, and a guide pin 27 that has the axial center provided in the upper link piece 21 in the left and right direction is fitted in the long hole 26 without play in the front and rear direction. It has been. With this configuration, when the lower link piece 20 swings in the direction of the arrow L (see FIG. 2), the upper link piece 21 swings around the connecting pin 22 in the direction of the arrow M (see FIG. 2). It is made like that. The connecting plate 25 is formed with a notch 28 (see FIG. 2) for escaping the rear pivot 18 when the lower link piece 20 and the upper link piece 21 come into close contact with each other. Yes.
[0011]
A lifting table 31, more specifically a bracket 32 provided on the lower surface of the lifting table 31, is pivotally connected to and connected to the upper end portion of the upper link piece 21 via a pivot 29 whose axis is directed in the left-right direction. . The lifting table 31 is moved up and down by bending of the link mechanism 19. When the elevating table 31 is raised while being pulled out from the article storage space 3, the upper surface of the elevating table 31 is flush with or substantially flush with the work surface 5. On the other hand, when the elevating table 31 is lowered, the elevating table 31 can enter the article storage space 3 without colliding with the top plate 7 or the storage body 2.
[0012]
A cover plate 35 is attached to the front lower link piece 20 of the left lift link device 16 and the front lower link piece 20 of the right lift link device 16 via a connecting piece 34. The cover plate 35 is horizontal in the state shown in FIG. 2, that is, in a state where the link mechanism 19 is in a straight line, and on the other hand, the link mechanism 19 is bent and the lower link piece 20 and the upper link piece 21 are in close contact with each other. Then, it is designed to be vertical. And if the raising / lowering table 31 is pushed in in the article | item storage space 3 in that state, the vertical cover board 35 will be contact | abutted on the front surface of the storage main body 2 (refer the dashed-dotted line of FIG. 2). In this state, a recess 37 is formed in the crosspiece 38 that is passed to the front of the storage body 2 so that the rear surface of the lower end of the cover plate 35 can be reached.
[0013]
At least one of the link mechanisms 19, in this embodiment, the link mechanism 19 at the rear left side in a state where the lifting table 31 is raised (the lower link piece 20 and the upper link piece 21 are in a straight line) A locking device 41 for locking the link mechanism 19 is provided.
The locking device 41 is formed on one of the upper and lower link pieces 21, 20, in this embodiment, the lever 43, which will be described in detail later, and the lower link piece 20 attached to the upper link piece 21 with a fixing pin 42. And an engaged portion 44 (in this embodiment, an upper edge portion of the opening 45) with which an engagement hook 48 formed on the lever 43 is engaged.
The lever 43 has a main body 47 whose upper part is elastic, an engagement hook 48 formed at the lower end of the main body 47, and an operation part 49 protruding to the left. The elastic portion of the main body 47 has a function of urging the engaging hook 48 in a direction to engage the engaged portion 44.
In FIG. 5, by pushing the operating portion 49 in the direction of arrow N, the engaging hook 48 can be removed from the engaged portion 44 and at the same time, the straight link mechanism 19 can be bent.
[0014]
The article storage space 3 other than the article storage space 3 in which the elevating table 31 is stored is openable and closable by a door as is well known.
[0015]
