Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a curtain plate mounting apparatus in a fixture, and more particularly, to attach a curtain plate to a frame that constitutes fixtures such as an assembly-type test bench, a similar work table, display stand or storage shelf, and a casing. The present invention relates to a curtain plate mounting device.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in fixtures such as an assembly-type laboratory bench, a frame is configured by connecting a horizontal beam member to a leg rod or a column, and a side plate, a curtain plate, a top plate and the like are attached to the frame and assembled. .
[0003]
For example, in Japanese Patent Laid-Open No. 8-238131 provided by the present applicant, an upper connecting member and a lower connecting member are connected to each other between upper and lower rear leg rods, and a curtain plate is provided between the upper and lower connecting members. A structure for mounting is disclosed. That is, a locking member is fitted on both sides of the upper edge of the curtain plate, and the lower edge of the curtain plate is placed in a concave groove having a quadrangular cross section of the lower connecting member, and the locking member is placed on the upper connecting member. It is attached to the upright piece of the reinforcing plate.
[0004]
However, in the mounting structure described above, the handle plate is held upright on the outer surface of the locking member with the curtain plate in a substantially vertical state, and after lifting the curtain plate upward, the lower end of the curtain plate is lowered. At the same time as dropping into the concave groove of the connecting material, a downwardly-opening locking groove provided on the back side of the locking member is dropped into the upright piece of the upper connecting material and locked. This is a work in a position where it cannot be seen from behind, and it is accompanied by the action of pinching the handle in a narrow space, so that not only the workability is bad, but the width of the concave groove is wider than the thickness of the curtain, and the width of the locking groove is Since the clearance is set wider than the thickness of the upright piece, there is a problem that the curtain is loose in the mounted state.
[0005]
[Problems to be solved by the invention]
In view of the above-mentioned situation, the present invention intends to solve the problem that the frame constituting the fixture such as an assembly-type test bench is between an upper beam member and a lower beam member that are horizontally provided with a space in the vertical direction. It is an object of the present invention to provide a curtain plate mounting apparatus in a fixture that can attach the curtain plate by a simple operation, can realize a stable mounting state without rattling, and can be easily detached.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a curtain plate mounting device in a fixture in which a curtain plate is detachably attached between an upper beam member and a lower beam member that are horizontally provided at an interval in the vertical direction. The lower frame member is supported on the lower beam member, and the upper frame member is erected on the upper frame member so that a holder attached to the upper edge of the curtain plate is detachably engaged with the upper beam member. An engagement edge having a substantially L-shaped cross section is formed, and the holder is engaged with a retaining piece that abuts against a lower end surface of the engagement edge and an upper end of the rising piece, and is vertically engaged. A curtain plate mounting device in a fixture is formed, in which a locking piece having elastic restoring properties is formed and a pulling piece protruding upward is integrally formed on the locking piece.
[0007]
Here, a protruding piece is formed between the receiving piece and the locking piece of the holding tool so as to abut the outer surface of the rising piece while the holding tool is engaged with the upper crosspiece member. Is preferred. In addition, an inclined plate inclined downward toward the curtain plate mounting side and a lower end edge of the inclined plate are mounted to support the lower end of the curtain plate along the upper surface side of the lower beam member. A bottom edge of the curtain plate by forming a support edge having a stop piece, supporting the lower end of the curtain plate on the lower end portion of the inclined plate and stopping the outer surface of the curtain plate against the stop piece It suppresses the rattling of this.

Further, as shown in FIGS. 5 and 7, a side plate 19 is attached to the space surrounded by the front leg rod 20, the rear leg rod 21, the upper horizontal rod 22 and the lower horizontal rod 23 of the leg member 16. That is, the upper horizontal bar 22 is formed with an engaging groove 29 opened downward, and the holding pieces 30, 30 inclined to the engaging groove 29 along the side edges of the engaging groove 29 are bent. Is formed. On the other hand, a single or a plurality of engagement holes 31 are formed on the upper surface of the lower horizontal bar 23. Then, after inserting the upper edge portion of the side plate 19 into the engagement groove 29 of the upper horizontal bar 22, the pins 32 and 32 projecting from the lower end of the side plate 19 by dropping downward are provided on the lower horizontal bar 23. It is mounted by dropping into the engagement holes 31 and 31.
[0022]
As shown in FIG. 8, the upper cross member 3 is screwed on the rear surface of the rear leg rod 21 with mounting plates 33 provided on both side ends, and the upper edge of the portion located between the rear leg rods 21, 21. The top plate 18 is screwed to the fixed plate 34 that is bent in the above manner, and the engaging edge 14 is bent in the lower edge.
[0023]
Further, as shown in FIG. 8, the lower crosspiece member 4 is screwed on the rear surface of the rear leg rod 21 with mounting plates 35 provided on both side ends, and is a portion located between the rear leg rods 21 and 21. The support edge 15 is bent at the upper edge, and a reinforcing folded piece 36 is formed at the lower edge and obliquely rearward and upward.
[0024]
As shown in FIG. 8, the curtain plate 1 is detachably attached between the upper beam member 3 and the lower beam member 4 as described above. That is, the holders 2 and 2 are attached to both sides of the upper end 1A of the curtain plate 1, the lower end 1B of the curtain plate 1 is mounted on the inclined end of the inclined plate 15A of the support edge 15 of the lower beam member 4, and the curtain. While the front side of the plate 1 is abutted against the back surface of the abutting piece 15B, the upright piece 14B of the upper cross member 3 is clamped from above and below by the receiving piece 7 and the locking piece 8 of the holders 2 and 2; The claw portion 11 is attached to the upper end of the upright piece 14B by being pulled out and engaged.
[0025]
In this way, when the experimental board is constructed by mounting and fixing the top plate 18 on the frame assembled by connecting both the leg members 16, 16 with the horizontal member 17 and the upper beam member 3 and the lower beam member 4, The members 16, 16 and the top plate 18 or the lateral member 17 form a footing space.
