Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an article storage fixture such as a cabinet provided with a height-adjustable top plate.
[0002]
[Prior art]
For example, in a wagon-type cabinet equipped with casters, making the height of the top plate adjustable means that the level of the top plate of the cabinet can be adjusted when using it attached to other desks. It is convenient because it can be aligned with the same surface to form a continuous wide work surface.
[0003]
In a conventional cabinet, a height adjustment mechanism consisting of a link or the like is provided between the main body storage unit and the top plate to adjust the height of the top plate or to fix the top plate to the lower end of the main body storage unit. Adjusters were installed at the four corners of the, and by adjusting this, the entire cabinet was moved up and down to adjust the height of the top plate.
[0004]
[Problems to be solved by the invention]
In the thing which adjusts the height of a top plate using the height adjustment mechanism which consists of the above-mentioned conventional links etc., since the structure of a height adjustment mechanism is complicated and there are many parts, it becomes expensive. Yes.
[0005]
In addition, since the height of the entire top plate is adjusted with respect to the main unit storage section, if the floor surface is inclined or uneven, the top plate is inclined in the same manner as the floor surface. Therefore, it is impossible to align with the top surface of the top plate such as a desk.
[0006]
On the other hand, in a cabinet having an adjuster at the lower end of the main body storage unit described above, if the height of the top plate is adjusted to be higher by the adjuster, the caster will be lifted from the floor surface. It is necessary to return the adjuster to the original position, and the work is troublesome.
[0007]
The present invention has been made in view of the above problems, and is inexpensive because the height and flatness of the top plate can be easily adjusted independently of the fixture body without being influenced by the state of the floor surface. It aims to provide a simple article storage fixture.
[0008]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) It consists of a fixture main body having an article storage section and a top plate provided on the upper portion thereof, and is directed vertically to any one of the four corners of the facing surface between the upper end of the fixture main body and the lower surface of the top plate. A female screw hole is provided, and a male screw portion formed at one end portion of the support pin is rotatably screwed into each female screw hole, and the other end portion of each support pin is connected to the fixture body or the top plate. the support tube of rigid a bottomed that fitted to the drilled concave hole such that the female screw hole facing pivotally loosely fitted into.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a wagon-type cabinet to which the present invention is applied, and FIG. 2 is a front view of the same. The cabinet (1) has a main body storage portion (4) having casters (2) at the lower four corners. 3) and a top plate (4) attached to the top.
[0010]
The main body storage portion (3) is configured by attaching a bottom plate (6) and a shelf plate (7) to the lower end and middle portion between the left and right side plates (5) and (5), and an open surface behind them. Is closed by a rear plate (8) attached between the rear ends of both side plates (5).
[0011]
The space surrounded by the top plate (4), the side plate (5), the bottom plate (6), the shelf plate (7) and the rear plate (8) is an article storage portion whose front is open.
[0012]
An edge member (9) made of synthetic resin or the like is fixed to the upper end surface of both side plates (5), and mounting holes (10) for the top plate (4) are formed in front and rear ends thereof. ing.
[0013]
The top plate (4) has a horizontally long rectangle that is slightly larger than the front / rear / left / right dimensions of the main body storage portion (3), and the bottom corners of the top plate (4) pass through the mounting holes (10) of the edge member (9). A support pin (11) that can be inserted into the side plate (5) is projected as follows.
[0014]
As shown in FIG. 3, at the left and right ends of the lower surface of the top plate (4), a belt-like support fitting (12) facing in the front-rear direction is provided on the lower surface of the top plate (4) by a plurality of countersunk screws (13). And a through hole (14) formed in the front and rear ends thereof, and an upward direction formed on the lower surface of the top plate (4) so as to communicate with the through hole (14). A female screw cylinder (16) having a flange at the lower end is press-fitted into the concave hole (15) from below.
[0015]
The lower end portion of each of the support pins (11) is a tapered small diameter portion (11a), and the lower end is a spherical surface.
[0016]
Each support pin (11) protrudes below the top plate (4) by screwing a male screw portion (17) engraved on the outer peripheral surface of its upper end portion into the female screw cylinder (16). It is attached in a manner.
[0017]
A fixing knob (18) as an anti-rotation member having a substantially thick disk shape is screwed onto the male thread portion (17) of each support pin (11), and the fixing knob (18) is viewed from the bottom. When rotating in the clockwise direction, the upper surface of the central portion is pressed against the lower surface of the female screw cylinder (16), thereby preventing the support pin (11) from rotating.On the other hand, when rotating in the counterclockwise direction, the support pin (11 ) Is allowed to rotate, and the vertical protrusion length can be adjusted.
[0018]
The small-diameter portion (11a) at the lower end of each support pin (11) passes through the attachment hole (10) of the edge member (9) so as to be rotatable, and the concave hole (19) at the upper end of the side plate (5). The bottom end of the support tube (20) is made of a metal or hard synthetic resin and is fitted into the bottom end of the support tube (20).
[0019]
The inner diameter of the mounting hole (10) and the support cylinder (20) of the edge member (9) is slightly larger than the outer diameter so that the support pin (11) can be slightly tilted.
[0020]
To attach the top plate (4) to the upper part of the main body housing (3), loosen the fixing knob (18), rotate each support pin (11), adjust the protruding length equally, What is necessary is just to insert in the four attachment holes (10) of the side plate (5), and to lock the rotation of the support pin (11) by the fixing knob (18).
[0021]
Thereby, the top plate (4) is horizontally supported in a state slightly separated from the upper end of the main body storage portion (3).
[0022]
When the height of the top plate (4) is matched with the height of the top plate of another desk or the like, the protruding length of the support pin (11) may be adjusted in the manner described above.
[0023]
Moreover, even when the top surface of the top plate (4) is inclined due to the inclination or unevenness of the floor surface, the projecting lengths of the four support pins (11) can be adjusted independently, and can be finely adjusted by screws. Since it can be adjusted, the top surface of the top plate (4) can be easily made flat by simply operating one of the support pins (11).
[0024]
When the height of the top plate (4) is adjusted, when the support pin (11) is rotated, the lower end thereof is a spherical surface and is in point contact with the inner bottom surface of the hard support tube (20). Resistance is small and can be easily rotated.
[0025]
Moreover, also when adjusting the flatness of the top plate (4), the support pin (11) can be easily tilted around the lower end.
[0026]
FIG. 4 shows a modified example of the height adjusting means of the top plate (4), and has a configuration opposite to that of the above embodiment.
[0027]
That is, a concave hole (21) is formed in the side plate (5) from which the edge member (9) is omitted, and a female screw cylinder (22) having a flange at the upper end is press-fitted into the concave hole (21). The support cylinder (24) is press-fitted into the upward concave hole (23) on the lower surface of the top plate (4), and the external thread part (26) formed at the lower end of the support pin (25) is connected to the internal thread cylinder. (22), and a tapered small-diameter portion (25a) at the top end is also inserted into the support tube (24) so that the top end of the spherical portion at the top is in contact with the back end surface. It is.
[0028]
The fixing knob (18) is screwed into the male thread portion (26) in the upside down direction, and the rotation of the support pin (25) is locked by tightening this.
Even in such a structure, when the support pins (25) are rotated, the upward projecting dimensions change, so that the height of the top plate (4) can be adjusted.
[0029]
When the edge member (9) as in the above-described embodiment is provided, a female screw to which the male thread portion (26) of the support pin (25) is screwed is formed in the mounting hole (10). The tube (22) may be omitted. At this time, the upper surface of the edge member (9) is preferably a flat surface so that the support pin (25) can be locked by the fixing knob (18) without any trouble.
[0030]
Of course, the present invention can also be applied to a cabinet without casters (2).
[0031]
【The invention's effect】
According to the first aspect of the present invention, since the height of the top plate can be freely adjusted by simply rotating the support pin and changing the projection dimension from the main body of the fixture or the top plate, the ceiling of another desk or the like can be adjusted. It can be easily aligned with the height of the plate.
[0032]
In addition, the four support pins are independent, and the height of the top plate can be adjusted independently from the main body of the fixture, so that the top plate can be easily adjusted to a flat surface without being affected by the state of the floor surface. can do.
Further, since the adjustment of the protrusion length of the support pin is a screw type, it is easy to finely adjust the height of the top plate.
Since the structure of the height adjusting mechanism is simple, the cost can be reduced.
[0033]
Since a hard support cylinder having a bottom is fitted into the concave hole, and the other end of the support pin is loosely fitted to the support cylinder, it is possible to prevent the back end face of the concave hole from being worn, The rotation operation of the support pin becomes easy.
