Description

[Detailed Description of the Invention] The present invention relates to an improvement of corner fixing fittings used for assembled shelves.

Generally, in steel shelves for displaying various goods,
Angle-shaped corner fixing fittings for assembling the four corner positions of shelf boards to the angle support at a predetermined number of steps are known, but the conventional products with relatively simple configurations are still in an assembled state. This may cause unsteadiness of the shelf board, distortion and deformation of the shelf board, and on the other hand, if the structure is complicated, there are problems such as increased costs and inconvenience during assembly work.

The present invention is intended to overcome these problems, and its specific configuration will be described in detail based on the illustrated embodiments as follows.

That is, in FIGS. 1 to 6, P is a relatively thick angle support made of steel, and the boundary corner of both perpendicular sides 10 that are perpendicular to each other when viewed from the plane is sharp as a flat corner surface 11. It is set so that it does not form a sharp ridgeline. And that corner surface 11
A plurality of bolt receiving holes 12 are open and arranged at regular intervals in the vertical direction. 13 is a pair of left and right bent pieces bent inward at right angles from both ends of both vertical sides 10;
It helps prevent injuries to hands and fingers.

S is a shelf board that is generally rectangular when viewed from above, and has a wide U-shape in cross section from a horizontally flat article placement surface 14 and a vertical side surface 15 that is bent downward at right angles. I am doing it. Furthermore, the vertical side surface 15 is folded in an upwardly inverted manner from the lower edge to the inside, and is integrated with the material, increasing its strength and preventing injury to hands and fingers, even though it is made of a thin steel plate. It is planned. Reference numeral 16 indicates a guide notch for bending provided at the corner of both vertical sides 15 that are orthogonal to each other.
The opening width is the corner surface 11 of the pillar P.
substantially corresponds to the width of the band. Reference numeral 17 denotes a pair of left and right assembly adjustment holes which are formed in the vicinity of the corners of both vertical side surfaces 15 so as to face each other across the guide notch 16, and have an elongated elliptical shape in the horizontal direction.

A is a corner fixing fitting for assembling and fixing the corner of the shelf S to the desired height position of the support P, especially to the top or bottom tier, and as shown in Figs. A dog-shaped plate piece type metal fitting main body A in plan view that can be fitted from the inside to both vertical sides 15 that intersect at right angles to each other.
1 and both vertical plate surfaces 18 in the metal fitting main body A1
A skirt piece A2 is extended and suspended continuously from a corner of the support post P so that it can be fitted from the inside.It is manufactured by sheet metal press working.

In that case, both vertical plate surfaces 18 of the metal fitting main body A1 are
Its height dimension is determined to be substantially equal to that of both vertical side surfaces 15 of the shelf board S, and its overall width dimension is similarly determined to be slightly wider than that of the support column P. Also, the corners of both vertical plate surfaces 18 are
The corner surface 19 is also flat and non-sharp so as to correspond to the corner surface 11 of the support P and maintain a parallel state. A threaded hole 20 that fits into the bolt-receiving hole 12 of the support column P is opened at approximately the center of this flat corner surface 19.

Numerals 21 are symmetrical protrusions that are cut outward as a pair of left and right from the midpoints of both vertical plate surfaces 18 of the metal fitting body A1, and are connected to the screw holes 20.
They are facing each other so that they are sandwiched between them. Both protrusions 21
are arranged in correspondence with the adjustment holes 17 of the shelf board S so as to engage with the adjustment holes 17 from the inside during assembly. Reference numeral 22 designates a pair of left and right tongue pieces that are bent outward at right angles from the lower edges of the lateral ends of both vertical plate surfaces 18, and are engaged with the lower end edges of both vertical side surfaces 15 of the shelf board S during assembly. , supports this from below, and at the same time, its overhanging tip part engages with the two bent pieces 13 of the column P, so that the column P is sandwiched between the two tongue pieces 22 of the column P from the width direction. Therefore, the length of the tongue piece 22 is set larger than the wall thickness of the vertical side surface 15 of the shelf S.

Furthermore, the center portion of the skirt piece A2 forms a flat corner surface 23 that is continuous with the flat corner surface 19 of the metal fitting body A1, and thus the support P
At the lower end thereof, a claw piece 24 that engages with another bolt-receiving hole 12 of the support P is bent outward at right angles. . In other words, the distance between the claw piece 24 and the screw hole 20 matches the vertical distance between adjacent holes 12 in the support P. Flat corner surface 23 of the skirt piece A2
However, the flat corner surface 19 of the fitting body A1
As suggested by the figure, it protrudes slightly outward.

Further, 25 is a conical projection protruding outward from the upper end of the flat corner surface 19 of the metal fitting body A1. When the bolt 26 is tightened, it hits the flat corner surface 11 of the support P from the inside, and together with the flat corner surface 23 of the skirt piece A2, the tightening margin (tightening margin) of the bolt 26 is increased. It acts as a guide to the end point of the degree of increase. In addition, the bolt 26 is as shown in the figure.
Preferably, a hexagonal head configuration with an overhanging flange is used.

When assembling the shelf S to the support post P using the fixing bracket A as described above, attach the support P to the corner of the shelf S from the outside, and attach the fixing bracket A from the inside as well.
In that case, as is clear from FIG. 7, the protrusions 21 on both vertical plate surfaces 18 of the metal fitting body A1 are engaged in the adjustment holes 17 of the shelf S, and the tongue pieces 22 are also overlapped. is engaged with the lower end edge of the shelf S. Then, the screw hole 20 of the metal fitting main body A1 and the blank hole 12 of the support post P are aligned, and the claw piece 24 of the skirt piece A2 is engaged with the blank hole 12 at a lower position different from the blank hole 12. In addition, one bolt 26 is screwed into the screw hole 20 from the outside and tightened.

Then, as shown in Figs. 8 to 13, both vertical sides 15 of the shelf S will be aligned with the fitting body A that fits there.
Both vertical plate surfaces 18 of 1 and both bent pieces 13 of support P
At the same time, both protrusions 21 of the metal fitting main body A1 are pressed against both adjustment holes 1 of the shelf board S.
7, the claw pieces 24 of the skirt piece A2 are engaged with the other tab holes 12 of the support P, while the both tongue pieces 22 of the metal fitting body A1 are also engaged with both vertical sides 15 of the shelf board S.
The shelf board S is supported from below, and is also secured to the bent pieces 13 of the support P from the left and right sides, so that the shelf board S is stable and robust without wobbling or distorted deformation as a whole. In the restrained state, it is assembled and fixed to the pillar P.

Moreover, both tongue pieces 22 of the metal fitting main body A1 and the claw pieces 24 of the skirt piece A2 are separated from each other based on the vertical positional relationship, and the claw pieces 24 face the center of the pillar P. While engaging with the hole 12, the pair of left and right tongue pieces 22 bend the double-folded piece 1 of the support P.
3 from the width direction, and furthermore, the conical protrusion 25 of the metal fitting body A1 and the flat corner surface 23 of the skirt piece A2 are also separated from each other in the vertical positional relationship. In order to impact-fit to the flat corner surface 11 of the support P, the shelf S is automatically assembled and fixed to the support P in an accurate horizontal position, and therefore, in order to maintain its horizontality, , for example, the double-folded piece 13 of the support P
There is no need to specially process notches for locking shelf boards, which are dangerous to handle, by creating several levels above and below them.

In addition, since the flat corner surface 19 of the metal fitting body A1 is provided with an outward protrusion 25 that guides the tightening margin of the bolt 26 with respect to the screw hole 20, over-tightening of the bolt 26 may cause the shelf to become damaged. Board S
There is no risk of the bolt tilting non-horizontally with respect to the support P, and anyone can perform the tightening work 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 are bent downward from the horizontal article placement surface 14.
Shelf board S with guide notches 16 in the corners of
Similarly, the corner portions of the perpendicular side surfaces 10 that are perpendicular to each other in plan view are set as flat corner surfaces 11 facing the guide notch 16 in a covering manner, and from both left and right end portions of both vertical side surfaces 10. Angle support P with a pair of bent pieces 13 bent inward
As a corner fixing bracket A to be assembled with a single bolt 26 inserted from the bolt receiving hole 12 opened in the flat corner surface 11, a corner fixing bracket A is attached to both vertical sides 15 of the shelf S from the inside. A metal fitting that has a shape of a dogleg plate piece in a plan view that can be fitted, and the corners of the orthogonal vertical plate surfaces 18 are set as a flat corner surface 19 corresponding to the flat corner surface 11 of the support P. A flat corner surface 19 of the main body A1 and the main body A1 extends from the corners of both vertical plate surfaces 18 of the main body A1 of the metal fitting A1 so that it can be fitted onto the support P from the inside. Skirt piece A provided with a flat corner surface 23 continuous with
The flat corner surface 19 of the metal fitting main body A1 has a screw hole 20 for screwing in a bolt that matches the bolt receiving hole 12 of the support P, and a screw hole 20 for screwing in the bolt.
In order to guide the tightening margin of the bolt 26 against the
Outward protrusions 25 abutting from the inside are provided on the flat corner surfaces 11 of the struts P, and from the midway of both vertical plate surfaces 18 of the metal fitting body A1, they face each other across the screw holes 20. At the same time, a pair of left and right protrusions 21 engage with assembly adjustment holes 17 opened on both vertical side surfaces 15 of the shelf S.
At the same time, both vertical plate surfaces 1 of the fitting body A1 are extended.
A pair of tongue pieces 22 which support both vertical side surfaces 15 of the shelf board S from below and at the same time lock both bent pieces 13 of the column P from the width direction are attached from both left and right ends of the column 8. At the same time, from the lower end of the flat corner surface 23 of the skirt piece A2, there is a claw piece 24 that engages with another bolt receiving hole 12 opened in the support P.
However, since it is bent outward,
Although the shelf board S can be easily assembled to the support post P with a single bolt 26, once it is assembled, the shelf board S cannot be moved vertically or horizontally by the fitting body A1. It is possible to reliably prevent misalignment, rattling, distortion and deformation, etc., and the shelf board S can be fixed and maintained in a horizontally assembled state on its own with respect to the support P in an extremely stable and robust manner, and its durability is also excellent. effective.

That is, the fixing metal fitting A that is fitted from the inside to both vertical side surfaces 15 of the shelf S has a pair of left and right protrusions 21 on the metal fitting main body A1 inserted into the adjustment hole 17 for assembly of the shelf S, and also a skirt piece A2. Both of the claw pieces 24 of the bracket P are engaged into the other tab holes 12 of the support P, and both tongue pieces 22 of the metal fitting main body A1 located above the claw pieces 24 touch the lower end edge of the shelf S. While supporting, the corner fixing bracket A is also locked in such a way as to pinch and restrict both bent pieces 13 of the support P from the width direction.
The screw hole 20 of the column P and the hole 12 of the support column P automatically match accurately, so that the bolt 16 can be inserted smoothly into the screw hole 2.
It can be screwed into 0.

Further, a projection 25 for guiding the tightening margin of the bolt 26 is projected outward from the flat corner surface 19 of the metal fitting main body A1, and this projection 25 and the skirt piece A
Since the flat corner surfaces 23 of both of the pillars P are designed to fit against the flat corner surfaces 11 of the support P, the screwed bolts 26 can be tightened easily and stably. There is no possibility that the horizontality of the shelf board S with respect to the support post P will be disturbed due to excessive force, or that the shelf board S will not wobble due to insufficient tightening. Anyone can perform assembly work extremely simply and efficiently without any worries.

Furthermore, 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 tongue pieces 22 on the fitting main body A1
supports both vertical side surfaces 15 of the shelf board S from below, and at the same time restrains both bent pieces 13 of the support P from the width direction so as to sandwich them. The claw piece 24 is engaged with the hole 12 of the support post P at the lower end spaced apart from the tongue piece 22, and the protrusion 25 of the metal fitting body A1 is engaged with the hole 12 of the support post P at the upper end spaced apart from the claw piece 24. Because of this, there is no risk that the shelf S will be misaligned along the vertical or horizontal directions of the support P, wobble, or tilt as a whole, resulting in extremely stable assembly accuracy. It can naturally achieve excellent fixing strength and can sufficiently withstand the loads of various articles placed on it.

In other words, in the present invention, the desired effect can be achieved through the organic bonding action of the constituent parts as described above, and the corner fixing fitting A as a whole can be easily manufactured by sheet metal press processing. Therefore, it can be said that it is a highly profitable product that can be mass-produced.
