Description

[Detailed Description of the Invention] The present invention relates to an improvement of a corner fixing fitting used in a so-called steel assembly shelf.

Generally, in steel shelves for displaying various goods,
It can be said that various angle-shaped corner fixing fittings for assembling the four corner positions of the shelf board to the angle support at a predetermined number of steps are known, but the conventional products with relatively simple structures are still in an assembled state. This may cause wobbling or distortion of the shelf board, resulting in poor stability and robustness. On the other hand, if the structure is complicated, the manufacturing and processing costs are high, and the assembly work cannot be performed efficiently.

The purpose of the present invention is to fundamentally solve these contradictory problems, and the specific structure thereof will be explained in detail based on the illustrated embodiments as follows.

That is, in FIGS. 1 to 7 that represent this, P
is a rigid angle support made of relatively thick steel material, and both vertical sides 1 are perpendicular to each other when viewed from the plane.
The boundary angle corner of 0 is curved as a flat corner surface 11 so as not to form a sharp ridgeline.
A plurality of bolt receiving holes 12 are arranged in the corner surface 11 at regular intervals in the vertical direction. Reference numeral 13 denotes a pair of left and right bent pieces that are bent inward at right angles from the lateral edges of both vertical sides 10, and are useful for preventing injuries to hands and fingers.

S is a shelf board that is square in plan view and is supported by the four angle supports P, and has a horizontally flat article placement surface 14 corresponding to a top plate, and a shelf board that is bent downward at right angles. With a total of four vertical side surfaces 15, it has a wide U-shape with a vertical cross section. In addition, each vertical side surface 15 is folded upward and inverted from the lower edge to the inside, and is integrally integrated with the other.Although it is made of thin steel plate, it is expected to increase its strength and prevent injury to hands and fingers. has been done. 16 are the two perpendicular sides 1
This is a notch for guiding bending formed at the corner of the angle support P, and its opening width substantially corresponds to the width of the band of the flat corner surface 11 of the angle support P.

Moreover, 17 is a pair of left and right protrusions disposed near the corners of both vertical side surfaces 15 so as to face each other with the notch 16 in between, and in particular, the cut protrusions at the folded overlapping portions of the vertical side surfaces 15. It is bent inward by a certain height. This protrusion 17 corresponds to and is engaged with an engagement hole of a corner fixing fitting to be described later, and to that extent, its size, protrusion height, protrusion cross-sectional shape, etc. may be adjusted appropriately. However, most preferably, as shown in FIGS. 2 to 4, a pair of left and right cut lines 18 of a certain length are cut in the vertical side surface 15 as running in the vertical direction, and a pair of cut lines 18 are cut inwardly between the two. The cross section is roughly dogleg-shaped toward the direction, and it is bent by a height h that corresponds approximately to the wall thickness of the above-mentioned folded overlapping portion, and the protrusion 17 is bent to a certain length w in the lateral direction (left-right direction). The rail will be set in the form of a long and narrow rail that will extend by the length of the rail.

In this way, although a pair of notch lines 18 are carved, it does not weaken both vertical sides 15 of the shelf S, which is generally thin and in which the notches 16 are formed, and the vicinity of the corners thereof are cut. This is because, while functioning as a reinforcing rib, it is possible to effectively prevent the shelf board S from being improperly deformed when tightening bolts, which will be described later. However, as will be explained again, for example, by bending only the inner sheet of the folded overlapping portion inward, the protrusion 17 may be formed into a cone-shaped or pyramid-shaped protrusion 17 without forming the cut line 18. This is because the shelf board S can be pressed in a so-called flat unfolded state. In any case, the tapered inclined surface of the protrusion 17 allows smooth and correct engagement with the engagement hole of the corner fixing fitting.

A is a corner fixing fitting for fixing the corner part of the shelf board S to the desired height position of the angle support P, especially the top or bottom tier;
Both vertical sides 15 of the shelf board S are orthogonal to each other as shown in the figure.
, a substantially dogleg-shaped metal fitting body A1 as a whole in a plan view that can be fitted from the inside thereof, and the metal fitting body A1;
It is manufactured by sheet metal press processing and consists of a skirt piece A2 that extends and hangs integrally and continuously from the corner of both perpendicular plate surfaces 19 that are orthogonal to each other so as to be able to be fitted from the inside to the angle support P. ing.

In that case, the height dimension of the pair of vertical plate surfaces 19 orthogonal to each other in the fitting main body A1 is determined to be substantially the same as that of both vertical side surfaces 15 in the shelf board S, and the overall width dimension is also determined as the angle. It is set slightly wider than that of the pillar P. Therefore, after assembly, it is impossible to visually recognize the fitting body A1 itself from the outside. Further, the corner portions of both vertical plate surfaces 19 are also non-sharp as flat corner surfaces 20 so as to correspond to the corner surfaces 11 of the angle support P and maintain a parallel state. At approximately the center of this flat corner surface 20, there is a screw hole 21 that fits with the bolt receiving hole 12 of the angle support P.
It has a through opening.

Further, reference numeral 22 denotes a pair of left and right engagement holes which are opened in the middle of both vertical plate surfaces 19 of the metal fitting main body A1, and are arranged symmetrically so as to sandwich the screw hole 21. As described above, this engagement hole 22 is
It engages with the protrusion 17 of the shelf board S, and in the case of the figure, it has an elongated rectangular opening in the horizontal direction corresponding to the protrusion 17. However, it goes without saying that the shape and size of the opening can be determined freely. and,
For example, by opening the engagement hole 22 to a certain extent larger than the protrusion 17, it is also possible to perform an adjustment operation when the two are assembled.

Reference numeral 23 designates a pair of left and right claw-shaped support pieces that are bent outward at right angles from the lower edges of the lateral ends of both vertical plate surfaces 19, and are engaged with the lower end edges of both vertical side surfaces 15 of the shelf board S during assembly. They are attached to each other and supported from below. Moreover, the protruding tip of the support piece 23 also engages with the particularly bent piece 13 of the angle support P, so that the angle support P is connected to both support pieces 23.
It is designed to be restrained in a sandwiching manner from the width direction (lateral direction). For this reason, the length of the support piece 23 is made larger than the thickness of the vertical side surface 15 of the shelf S.

The center part of the skirt piece A2 is the metal fitting body A1.
It forms a flat corner surface 24 that is continuous with the flat corner surface 20 of the angle support P, and is designed so that it can be fitted from the inside to the angle support P. Tongue piece 2 that engages with bolt receiving hole 12
5 is also bent outward at right angles.
In other words, the distance between the tongue piece 25 and the screw hole 21 is substantially the same as the vertical distance between adjacent blind holes 12 in the angle support P. As suggested by the figure, the flat corner surface 24 of the skirt piece A2 projects slightly higher outward than the flat corner surface 20 of the fitting body A1.

Further, 26 is a conical protrusion protruding outward from the upper end of the flat corner surface 20 of the metal fitting main body A1. When the bolt 27 is tightened, it hits the flat corner surface 11 of the angle support P from the inside, and together with the flat corner surface 24 of the skirt piece A2, the bolt 2
It acts to guide the tightening margin (end point of the degree of tightening) of No. 7, and in that sense, it is not limited to the protruding form as shown in the figure. For example, it is possible to bend it into an L-shape or the like from the flat corner surface 20 of the metal fitting main body A1, and in any case, the workability is improved by its installation. It is preferable that the bolt 27 has a hexagonal head with an overhanging flange as shown in the figure.

When assembling the shelf S to the angle support P using the fixing fittings A as described above, the shelf S
The angle support P is superimposed on the corner of the frame from the outside, and the fixing metal fitting A is overlapped from the inside as well, but in that case, as is clear from Fig. 8, the metal fitting body A1
The engaging holes 22 opened in both vertical plate surfaces 19 of Lock it to the lower edge. and,
The screw hole 21 of the metal fitting body A1 and the angle support P
At the same time, the tongue piece 25 of the skirt piece A2 is engaged with the cover hole 12 at a lower position or an upper position (when used in an upside-down position), which is different from the cover hole 12. Then, one bolt 27 is screwed into the screw hole 21 from the outside and tightened.

Then, as shown in FIGS. 9 to 15, both vertical side surfaces 15 of the shelf board S are fixed by both vertical plate surfaces 19 of the fitting main body A1 that are fitted thereto, and by both bent pieces 13 of the angle support P. At the same time, both the engagement holes 22 of the metal fitting main body A1 and both the protrusions 17 of the shelf board S engage with each other, and the tongue piece 25 of the skirt piece A2 also engages with the angle support P. While engaging with another hole 12 of the metal fitting body A1, both supporting pieces 23 of the metal fitting main body A1 engage with both vertical side surfaces 1 of the shelf board S.
5 is supported from below, the shelf S will not wobble or distort from any direction, and will be assembled and fixed to the angle support P in a stable and robust state as a whole. Become,
This effect is further improved because the restraining action of the support pieces 23 that sandwich the angle support P from both left and right sides is also added.

Further, as is clear from the figure, both support pieces 23 of the metal fitting main body A1 and the tongue piece 25 of the skirt piece A2 are separated from each other in a vertical positional relationship, and the tongue piece 25 is located at the center of the support column P. While facing the support P, the support pieces 23 engage the bolt-receiving holes 12 of the support P, and the pair of left and right support pieces 23 pinch and restrict the bent pieces 13 of the support P from the width direction (lateral direction). Furthermore, the conical protrusion 26 of the metal fitting body A1 and the flat corner surface 24 of the skirt piece A2 are separated from each other based on the vertical positional relationship, and both of them are connected to the flat corner surface 11 of the support P. As a result, the shelf S is automatically assembled and fixed in an accurate horizontal position to the support P. Therefore, in order to maintain the horizontality of the shelf S, for example, the support P is There is no need to specially process the sawtooth notches for locking the shelf board, which are extremely dangerous in handling the double-folded piece 13, by creating several steps above and below it.

Furthermore, the flat corner surface 20 of the metal fitting body A1
is provided with an outward protrusion 26 that guides the tightening margin of the bolt 27 that is screwed into the screw hole 21, so if the bolt 27 is overtightened, the shelf S will become attached to the support P. There is no risk of tilting or damaging the threads later on, and the shelf board S will not rattle against the support P due to insufficient tightening, and anyone can tighten the bolts 27. It can be done stably and easily.

As described above, in the present invention, the vertical side surfaces 15 that are perpendicular to each other in plan view are bent downward at right angles from the horizontal article placement surface 14, and both vertical side surfaces 15
A shelf board S having a notch 16 for bending guide at the corner of the shelf board S is formed so that the corner parts of the perpendicular sides 10 that are perpendicular to each other in plan view cover the notch 16 of the shelf board S. An angle support P that is set as a facing flat corner surface 11 and has a pair of bent pieces 13 bent inward from both left and right ends of both vertical side surfaces 10.
1, which is inserted through the bolt-receiving hole 12 opened in the flat corner surface 11 of the support P.
The corner fixing fittings A to be assembled via book bolts 27 have a dogleg shape in plan view that can be fitted from the inside to both vertical side surfaces 15 of the shelf S, and the corner fixing fittings A are shaped like a dogleg plate in plan view, and can be fitted from the inside to both vertical side surfaces 15 of the shelf S. A corner of the plate surface 19 is set as a flat corner surface 20 corresponding to the flat corner surface 11 of the support P, and a corner of both vertical plate surfaces 19 in the fitting main body A1. , consisting of a skirt piece A2 that extends and hangs down so as to be able to be fitted from the inside to the support P, and is provided with a flat corner surface 24 in the center thereof that is continuous with the flat corner surface 20 of the metal fitting main body A1, The flat corner surface 20 of the metal fitting main body A1 has a screw hole 21 for screwing in a bolt that matches the bolt receiving hole 12 of the support P, and
In order to guide the tightening margin of the bolt 27 against the bolt 27, an outward convex portion 26 is provided which abuts from the inside on the flat corner surface 11 of the support P, and also in the middle of both vertical plate surfaces 19 in the metal fitting body A1. A pair of left and right engagement holes 2 are provided in the section, facing each other so as to sandwich the screw hole 21 therebetween, and engaging with protrusions 17 bent inward from both vertical side surfaces 15 of the shelf S.
2 is formed into an opening, and both vertical plate surfaces 1 of the fitting main body A1 are also formed.
A pair of supporting pieces 23 that support both vertical side surfaces 15 of the shelf board S from below and also lock the bent pieces 13 of the support column P from the lateral direction are attached from both left and right ends of the support plate 9 outward. At the same time, from the lower end of the flat corner surface 24 of the skirt piece A2, a tongue piece 25 that engages with another bolt receiving hole 12 opened in the flat corner surface 11 of the support column P is also inserted. Due to the structure that is bent outward, it is possible to assemble the shelf S to the support P with a single bolt 27 very easily, but once it is assembled, it cannot be fixed. The metal fittings A can reliably prevent misalignment, wobbling, distortion, etc. of the shelf S in the vertical and vertical directions, as well as in the horizontal and horizontal directions. , it can be assembled and maintained extremely stably and robustly, and its durability is also excellent.

That is, first of all, regarding the assembly work, in the case of the corner fixing fitting A according to the present invention, the fitting body A
1, both vertical side surfaces 19 of the shelf S
Engagement hole 22 with protrusion 17 extending inward from 5
is formed with an opening, and both vertical plate surfaces 19
From the lower edge of both left and right ends of the shelf board S, both vertical sides 1
Since the pair of support pieces 23 that support the shelf board S from below are also bent out, as is clear from FIG. It can be kept in a fixed state, and the angle support P can be attached to the shelf S in that state from the outside.
Since all you have to do is to overlap them, the assembly work can be done extremely easily.

When stacking the support P on the temporarily assembled shelf board S from the outside, the tongue piece 25 of the skirt piece A2 is inserted into the bolt receiving hole 12 of the support P.
while engaging both support pieces 2 of the metal fitting main body A1.
3 to the double-folded pieces 13 of the support P from the lateral direction, the screw hole 21 for screwing in the bolt of the metal fitting main body A1 and another bolt receiving hole 12 of the support P are connected. will automatically match correctly, and the swinging movement of the shelf S and fixing fittings A relative to the support P will also be regulated in a firm and stable position, making it very difficult to screw in the bolts 27 and tighten them. It can be done easily.

In that case, the flat corner surface 20 of the fitting main body A1 also has an outwardly protruding protrusion 26 for guiding the tightening margin of the bolt 27, and this protrusion 26 and the flat corner surface 24 of the skirt piece A2 are connected to each other. , are designed to be butt-fitted to the flat corner surface 11 of the support P, so anyone can smoothly tighten the bolts 27, and the position of the shelf S due to over-tightening will be avoided. No, there is no need to worry about the shelf board S wobbling due to insufficient tightening.

Next, regarding the state after the shelf board S is once assembled to the support P using the corner fixing fitting A of the present invention, the pair of left and right supporting pieces 2 of the fitting main body A1
3 not only supports both vertical side surfaces 15 of the shelf S from below, but also locks and restricts both bent pieces 13 of the support P from the lateral direction. On the other hand, at the center position of the fixing fitting A, the tongue piece 25 of the skirt piece A2 is attached to the fitting body A.
The lower end part separated from the supporting piece 23 of 1 engages with the bolt receiving hole 12 of the support P, and the upper part separated from the tongue piece 25 engages with the bolt tightening margin guide convex part of the fitting main body A1. child 26
As a result, the shelf S as a whole hits the pillar P in a tensioned manner from the inside, causing the shelf S as a whole to become misaligned along the vertical, horizontal, and horizontal directions of the pillar P, or to become unstable. There is no risk of the device sticking or tilting, and it can naturally achieve extremely stable assembly accuracy and excellent fixing strength, and can sufficiently withstand the load of each article placed on it.

In other words, although the present invention uses a single bolt 27 to assemble the shelf board S to the support P, it is not possible to achieve the intended purpose for the first time through the organic coupling of the constituent parts as described above. can be achieved, and this point has special technical significance.

The corner fixing fitting A as a whole can be easily mass-produced by simple sheet metal press processing, and can also be used as a member to which the tongue piece 25 of the skirt piece A2 is engaged. Since the hole 12 is also used, it can be said that the design is extremely rational, and it is extremely excellent in practical use as a product that is used in large quantities.
