TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connection device that can easily connect a shelf device such as a rack and a similar shelf device or furniture such as a cabinet.
[0002]
[Prior art]
Conventionally, such a connection between a shelf device and a fixture is, for example, in the case of a lightweight shelf and a cabinet, when manufacturing them, a connection hole is drilled at a predetermined height of their side plates and the like, and the connection holes are formed. The bolts and nuts passed through were tightened.
[0003]
[Problems to be solved by the invention]
In the connection between the existing connection holes described above, depending on the condition of the floor to be installed, the heights of the connection holes may be slightly different in front, rear, left and right, and it may be difficult to match the positions.
In addition, when stacked and installed, the pitch of the connection holes may be shifted from each other, and the existing connection holes may not be used. Therefore, the number of connection points is reduced and the connection strength is reduced. .
Furthermore, when connecting a cabinet and a rack having a different structure from the rack, instead of the racks, it may be necessary to newly process connection holes or the like in one or both of the racks. There is a possibility that the dimensions may be violated, the mounting position of the shelf board may be limited, or the contents may be damaged by connecting screws or the like.
[0004]
The present invention has been made in view of the above-described conventional problems, and can easily and reliably connect using existing connection holes in a cabinet or the like without performing new processing on furniture such as a shelf device or a cabinet to be connected. It is an object of the present invention to provide a simple connecting device that can be used.
[0005]
[Means for Solving the Problems]
According to the present invention, the above-mentioned problem is solved as follows.
(1) Forming engaging portions for engaging at least a part of the pillars at both front and rear ends of a vertically movable connecting member extending between the front and rear pillars on one side of the shelf device having pillars arranged at four corners; And, in the middle part of the connecting member, a connecting hole for screwing to a side plate or the like of a fixture adjacent to the side of the shelf device is provided , and an opening is provided on the rear surface of the front column or the front surface of the rear column. Then, an end of the connecting member is fitted into the opening, and the engaging portion of the connecting member is engaged with a flange formed on an opening edge of the support.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example in which rack-type assembled shelf devices (1) are connected side by side to a cabinet (2).
That is, the side plate (3) of the cabinet (2) and the side surface of the shelf device (1) formed by the outer surfaces of the front and rear columns (4) and (5) adjacent thereto are connected by the connecting device of the present invention.
[0007]
2 and 3 are views showing an embodiment of the connecting device of the present invention. The side plate (3) of the cabinet (2) is provided with a connecting hole (6) at a predetermined height at the time of manufacturing. Is established.
[0008]
In the shelf device (1), a pair of front left and right columns (4) and (4) and a pair of rear left and right columns (5) and (5) are formed by bending a steel plate so as to form a symmetrical channel shape. Vertically continuous openings (7) are formed in the center of the rear surface of the front column (4) and the front center of the rear column (5), and both side edges of each opening (7) are formed. The front support (4) is formed with flanges (4a) and (5a) bent forward at right angles, and the rear support (5) is formed at right angles.
[0009]
Also, recessed steps (4b) and (5b) are formed at the inner corners of the columns (4) and (5) in the left-right direction and at the outer corners in the front-rear direction. On the inner surface of each of the columns (4) and (5), a number of engaging holes (8) for locking a bracket for supporting a shelf board or a horizontal rod (both not shown) are equally spaced in the vertical direction. It is drilled with.
[0010]
A connecting member (9) is provided horizontally between the front and rear struts (4) and (5).
The connecting member (9) is formed by bending a steel plate into a U-shaped cross section when viewed from the front, and the outer surfaces of the front and rear ends fitted into the openings (7) of the front and rear columns (4) and (5). A groove-shaped engaging portion (9a) that engages with the outer flanges (4a) and (5a) is formed on the outer surface.
In addition, a connecting hole (10) is formed in an intermediate portion of the connecting member (9) at front and rear positions corresponding to the connecting hole (6) of the cabinet (2).
[0011]
As shown in FIG. 2, such connecting members (9) are engaged with engaging portions (9a) at both front and rear ends thereof with inner flanges (4a) and (5a) of columns (4) and (5). Then, it is moved up and down while maintaining the horizontal state, and brought up to a position where the connecting hole (10) is aligned with the connecting hole (6) formed in the side plate (3) of the cabinet (2). Then, the connecting member (9) is fastened to the side plate (3) with a set screw (11) or a bolt nut.
In this manner, the connecting member (9) is firmly connected to the columns (4) and (5) via the engaging portions (9a), and the connection between the shelf device (1) and the cabinet (2) is achieved. It is.
[0012]
The cross-sectional shapes of the columns (4) and (5), in particular, the engaging portions with the connecting member (9), and the shapes of the engaging portions (9a) at the front and rear ends of the connecting member (9) are shown in FIG. Other shapes as shown in FIG. 4 can also be used.
Also, by connecting two similar back-to-back connecting members with a set screw or the like, the shelf devices (1) and (1) having the same configuration can be easily connected to each other.
[0013]
【The invention's effect】
According to the present invention, since the connecting member is only hooked on the support during the connecting operation and is not fixed to the support, it can be adjusted in the height direction to the position of the connection hole of the fixture of the other party, so that fine adjustment of the adjuster or the like can be performed. No components are required, and no labor such as drilling on site is required, and components having different heights can be easily and reliably connected.
[0014]
And an end portion of the consolidated material is fitted into the strut, engaging good appearance because not exposed to the outside, also, the flange engaging portions of the connecting member are engaged, a bracket or the like of the shelf plate support in posts Since the connecting member can be provided apart from the engaging hole for stopping, the connecting member does not limit the mounting position of the shelf board, and the shelf board can be supported at a desired height.
