Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a locking device for a shelf support bracket when supporting a shelf through a support such as in a display device.

[Conventional technology]

When supporting a shelf through a support in a display device, etc., the shelf support bracket is locked to the support and the shelf is placed on this shelf support bracket. As described in Japanese Utility Model Application Publication No. 57-68664, the conventional means for locking the holder is to drill locking slots at regular pitches along the vertical direction in the front plate of the hollow pillar. The locking pawl of the shelf support bracket is inserted into the locking slot and engaged.

[Problem that the invention attempts to solve]

However, since this type of support is often made using a square pipe or formed by extrusion processing of aluminum, when drilling the locking groove, it is necessary to drill the locking groove in front of the support that has been formed hollow in advance. The face plate will be punched with a press, but it is not easy to punch holes in the side of a hollow member with a press due to problems such as distortion, so it takes time and effort to drill the locking grooves. I used to be. In addition, since the load applied to the shelf support bracket acts as a pressing force on the front plate of the column, the support strength for the bracket is proportional to the thickness of the column's front plate. Since the thickness of the brackets is constant, the support strength for the shelf support brackets also remains unchanged, and when heavy objects are placed on the shelves, there is a problem in that the supports themselves have to be replaced.

As a means to solve this problem,
In Publication No. 99307, an opening groove is formed in the front surface of a hollow support column over its entire length, and a support having a U-shaped cross section is inserted into the hollow part of the support support, and a shelf plate is installed in the front surface of the support. A technique is proposed in which locking grooves into which the base locking claws of the support bracket fit are bored at appropriate intervals.

However, according to this configuration, the support is formed in a U-shape, so even though the thickness of the support itself is thin, the space for storing the support increases in the depth direction of the support. The dimensions will be larger than necessary.
Another problem was that it required time and effort to form the support into a U-shaped cross section.

The present invention reduces the effort required to manufacture the support struts and the locking devices for the support brackets, and also enables a single support support to support both light and heavy objects on the shelf board.

[Means for solving problems]

In other words, in the present invention, the front plate of the hollow support is
An opening groove into which the base of the shelf support bracket can be inserted is formed over approximately the entire length of the column, and a bracket support plate having locking slots drilled at appropriate intervals along the vertical direction is inserted into the hollow part of the column, In the shelf support bracket locking device, the shelf support bracket is removably locked to the bracket support plate from the front of the support column, wherein the front plate and the front plate are attached to both left and right inner surfaces of the hollow part of the support support plate. A pair of left and right support ribs extending inwardly across a gap are provided protruding over substantially the entire length of the column, and the pair of left and right support ribs are
The support ribs are formed in a stepped manner in the front and back so that the gap between the support ribs and the front plate is smaller at the root of the inner surface of the support and larger at the tip, and the gap between the support rib and the front plate of the support is The structure is such that different strip-shaped bracket support plates can be inserted and replaced interchangeably.

[Action/Effect]

With this structure, the bracket support plate inserted into the gap between the front plate of the column and the pair of internal left and right support ribs has its left and right edges sandwiched between the front plate of the column and the support ribs. Since the shelf support bracket is held in such a way that it cannot tilt back and forth, the shelf support bracket is fixed to the support column by dropping the locking pawl of the shelf support bracket into the locking groove hole of the bracket support plate through the opening groove on the front surface of the support column and engaging it. The shelf board is supported by the shelf support bracket.

Support ribs protruding from the left and right inner surfaces of the hollow part of the column are formed in a stepped manner in the front and back such that the gap between the support rib and the front plate of the column is smaller at the base of the inner surface of the column and larger at the tip. Therefore, in the gap between the pair of support ribs and the front plate of the column, there is a bracket support plate whose width is approximately the same as the dimension between the left and right inner surfaces of the column and which is thin, and a space between the stepped portions of the left and right support ribs. This means that a bracket support plate having substantially the same width and thicker thickness can be inserted and replaced.

Therefore, according to the present invention, it is sufficient to provide the support column with an opening groove and a support rib extending along its longitudinal direction, and the support column may be simply formed by extrusion processing of aluminum. Since this can be easily and precisely drilled simply by pressing the locking groove in the strip plate, it is possible to drill the locking groove in the support itself, or the support as in the above-mentioned Japanese Utility Model Publication No. 59-99307. Compared to a structure in which a locking slot is bored in a support having a U-shaped cross section to be inserted into the support, the effort required for manufacturing can be reduced. In addition, since the bracket support plate that is inserted into the column is in the form of a strip, the depth of the space required to insert the bracket support plate can be reduced, and the front and rear width of the column can be made larger than necessary. It can also be prevented.

Moreover, since bracket support plates of different thicknesses can be replaced and inserted into the pillars, when placing heavy objects on the shelf board, it can be handled by replacing the bracket support plates with thicker ones. It also has the effect that the support can be used for both light and heavy objects.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes hollow pillars fixed to the wall surface A of the chamber at appropriate intervals on the left and right, and reference numeral 2
1 and 2 respectively show wall panels attached via the support columns 1, and the support columns 1 are capable of supporting shelf boards 4 via shelf support brackets 3 by the following configuration.

That is, an opening groove 5 having a width slightly larger than the plate thickness of the shelf support bracket 3 is formed in the left and right intermediate portions of the front plate 1a of the column 1, and extends over the entire length of the column 1. A pair of left and right guide pieces 6, 6 are provided protruding forward with the opening groove 5 in between, while on the left and right inner surfaces in the hollow part of the support column 1,
A pair of left and right support ribs 7, 7 extending inwardly with an appropriate gap from the front plate 1a are provided projecting over the entire length of the column 1, and upper and lower support ribs 7, 7 are provided in the gap between the support ribs 7 and the front plate 1a. By inserting the bracket support plate 8 having protruding locking slots 8a at regular intervals, the locking claws 3a of the shelf support bracket 3 inserted through the opening groove 5 can be fixed to the locking claws 3a of the bracket support plate 8. The shelf board 4 is supported through the shelf support bracket 3 which is inserted into the locking slot 8a and is thus locked.

In this case, both the left and right support ribs 7 are formed in a stepped shape in the front-rear direction, and the gap distance with the front plate 1a is approximately the same dimension (s1) as that of the front plate 1a at the base, and the gap at the base of the tip 7a is approximately the same as that of the front plate 1a. By forming the gap between the front plate 1a and both supporting ribs 7 to have a width approximately equal to the dimension between the left and right inner surfaces of the column 1, The bracket support plate 8, which is a thin plate in dimensions, and the bracket support plate 8', which is a thick plate and whose width is approximately the same as the interval between the stepped portions of the left and right support ribs 7, can be inserted and inserted interchangeably.

Further, an engagement groove 1b having a semicircular cross section is formed on the left and right outer surfaces of the support column 1, and a flange piece 9 is provided on the back side of the left and right side edges of the wall panel 2 to protrude backward. A locking body 10 made of spring steel having a free end extending outward and formed into a locking part 10a having a semicircular cross section with an outward convex shape is fitted, and the locking part 10a of the locking body 10 is fitted into the locking part 10a of the locking body 10. By engaging and disengaging the fitting groove 1b, the wall panel 2 can be detachably attached to the support column 1.

Incidentally, a top rail 11 and a ground rail 12, which surround the wall panel 2 from above and below, are fixed to both the upper and lower ends of the wall surface A.

In the above configuration, the shelf support bracket 3 is inserted between the left and right guide pieces 6, and the locking claw 3a of the shelf support bracket 3 is inserted into the locking groove hole 8a of the bracket support plate 8 through the opening groove 5. By dropping the bracket into engagement with the support bracket 3, the shelf support bracket 3 can be locked at an arbitrary height position with respect to the column 1.

In that case, the load applied to the shelf support bracket 3 is transferred to the locking slot 3 with respect to the bracket support plate 8.
Since it acts as a pressing force below a, the support strength for the shelf support bracket 3 is proportional to the thickness of the bracket support plate 8. However, in the present invention, since the support ribs 7 are formed in different steps in the front and back, when a lightweight object is placed on the shelf board 4, a thin bracket support plate 8 is inserted and the shelf board 4 is
If a heavy object is to be placed on the bracket, this can be done by inserting a thick bracket support plate 8'.

Note that the back surfaces of the bracket support plates 8, 8' are in contact with the entire upper and lower sides of the support rib 7, and the pressing force from the bracket support plates 8, 8' acts on the partition plate 7 in a distributed manner. Even if the bracket support plate 8' is brought into contact with the tip end 7a of the support rib 7, the support rib 7 will not be deformed. In addition, pillar 1
Providing a pair of left and right guide pieces 6 protruding from the front plate 1a has the advantage of preventing the locked shelf support bracket 3 from moving left and right.

In this way, since the opening groove 5 and the support rib 7 of the column 1 extend along the longitudinal direction of the column 1, the column 1
can be easily formed by extrusion of aluminum, etc., while the bracket support plates 8, 8' are band-shaped and the locking slots 8a can be formed extremely easily and precisely by press working, so the support itself The manufacturing effort is reduced compared to those in which a locking slot is bored in the support or in which the support for supporting the shelf support bracket inserted into the support is formed to have a U-shaped cross section. Further, since the bracket support plates 8, 8' are band-shaped, the depth dimension of the space occupied in the hollow portion of the support column 1 can be reduced, so that the longitudinal width of the support column 1 is prevented from becoming larger than necessary.

Moreover, since the bracket support plates 8 and 8' of different thicknesses can be replaced and inserted into the column 1, when placing heavy objects on the shelf board 4, it is possible to replace the bracket support plates 8 and 8' with the thicker bracket support plates 8'. The support column 1 can be used both for supporting light objects and for supporting heavy objects.
