[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner bracket for an assembling type shelf in which a shelf is removably mounted on a column.

[0002]

2. Description of the Related Art Normally, a modular shelf is shown in FIGS.
As shown in the figure, four pillars 21 made of angle steel are erected so as to be rectangular in plan view, and four corners of a shelf plate 22 made of a thin steel plate are fastened to these pillars 21 by bolting or the like. It is formed by this.

Conventionally, as shown in FIG. 18, for example, a corner bracket 2 which is bent symmetrically between the support column 21 and the shelf plate 22 has a substantially triangular shape.
3 and the upper end of the corner bracket 23 is bottled with the upper end of the corner bracket 23 disposed between the side wall 24 of the column 21 and the side plate 25 of the shelf board 22. By bolting the portion to the side plate 25 of the shelf plate 22 and the side wall portion 24 of the column 21,
The connecting portion between the shelf plate 22 and the column 21 is reinforced by the corner bracket 23.

Further, as shown in FIG. 19, a pair of corner brackets 23 which are separately separated and left-right symmetrical are formed into one set, and this set is used as described above for the shelf plate 22.
There is also one that is interposed between the side plate 25 of FIG.

[0005] That is, in the conventional assembly type shelf described above, by using the corner bracket as described above, the contact area of the connecting portion between the shelf plate and the column can be increased, so that it is simple. The configuration has the advantage that this connection can be effectively reinforced.

[0006]

However, the shelf plate 22 and the column 21 are basically connected to the corner bracket 2.
Since they are connected only by bolting via 3, a considerable number of bolts are required. And the bolt holes in each place where the bolts are inserted are usually elongated holes to flexibly correspond to the alignment, and as a result, there is play for the bolts that are fastened, and even when tightened with bolts The bolt moves in the play due to the external force applied to the shelf, and the shelf tilts.

Therefore, in order to avoid such inconvenience, bolts are extremely strongly tightened. However, the number of bolts is large, so that the operation of assembling the shelf is complicated and requires a lot of time. Even if the rack is firmly tightened, in the case of a shelf which is installed in a place where vibrations occur, there is a problem that the vibration loosens the fastening force of the bolts and causes rattling on the shelf.

Further, in the conventional corner bracket 23, a hypotenuse portion of a triangle formed by connecting an insertion hole for passing a bolt provided on a wall surface thereof is cut out so as to be curved inward. For this reason, the effect as “haze” has been diminished, and a so-called “triangle does not appear” state, which is called by a person skilled in the art. Therefore, unless the corner bracket 23 is made to have a considerable thickness, there is an inconvenience that the shelf board 25 cannot be reliably supported without play.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a simple structure can easily and effectively reinforce the connecting portion between a shelf plate and a column, and the connecting portion has a play. It is an object of the present invention to provide a corner bracket for a modular shelf that can be effectively prevented from occurring.

[0018]

According to the corner bracket for an assembling shelf according to the first aspect of the present invention, the insertion hole formed on the wall surface of the corner bracket or the line connecting the projections forms a triangle. Alternatively, since the protrusion is arranged and the wall surface of the corner bracket is present outwardly from the portion corresponding to the hypotenuse of the triangle, the locking portions at both ends of the hypotenuse approach each other. Even if a large compressive force is applied (that is, a force such as a rattling of the shelf) is applied, the oblique side portion has a wall surface, and can sufficiently cope with the above-described compressive force. In other words, the corner bracket according to the present invention can sufficiently and reliably perform the function of "blurring", and can effectively suppress the rattling of the shelf in the horizontal direction.

When the corner bracket has a bulged portion having a contact surface that comes into contact with the side wall of the column, the corner bracket is joined to the corner of the shelf from the inside of the side plate. In the state, the bulging portion is located in the gap formed between the outer surface of the wall surface of the corner bracket and the inner surface of the side wall portion of the column, and the gap is filled, so that the column and the shelf plate are attached and locked by the corner bracket. In this state, the corner bracket and the support come into direct contact, the contact area increases, and the support and the shelf board are connected more firmly.

When the corner bracket has a bulged portion having an abutting edge for abutting against the side plate of the shelf, the support and the shelf are joined together via the corner bracket. Since the lower edge of the side plate of the shelf is supported by the abutting edge of the bulging portion, the shelf is supported by the column in a state where it is difficult for rattling to occur stably.

As described above, by forming the bulging portion on the corner bracket, the column and the shelf board are more firmly connected to each other via the corner bracket than before, and the placing load of the article on the shelf board is increased. Sufficient support stiffness can be ensured.

According to the corner bracket for an assembling shelf according to the second aspect of the present invention, the first projection is formed on the wall surface of the corner bracket to be engaged with the engagement hole formed in the side wall of the column. Since the second projection is formed to be engaged with the engagement hole formed in the side plate of the shelf, the bolting can be omitted at this portion, and the assembling operation is simplified.

According to the corner bracket for a modular shelf according to the third aspect of the present invention, the bulging portion is formed so as to protrude outward over the entire lower surface of the wall of the corner bracket. The contact edge is formed at the upper edge of the
Since this corner bracket is arranged on the inner surface of the corner portion of the side plate of the shelf plate and is configured such that the side plate of the shelf plate is supported by the abutting edge, the entire lower surface of the wall surface of the corner bracket is the inner surface of the side wall portion of the column. And the contact area is maximized, the shelf is supported by the upper edge of the bulging portion, and the column and the shelf are more firmly connected to each other, and the shelf is rattled. Can be more effectively deterred.

According to the corner bracket for a shelf of the present invention, the bulging portion is formed at a lower portion of the wall surface of the corner bracket so as to protrude inward.
The abutting edge is formed at the upper edge of the bulging portion, and the corner bracket is disposed so as to be sandwiched between the column and the shelf, and the abutting edge supports the side plate of the shelf. , The rattling of the shelf is more effectively suppressed.

According to the corner bracket for an assembling shelf according to the fifth aspect, the bulging portion is formed at a lower portion of the wall surface of the corner bracket so as to protrude outward.
The contact edge is formed at a side edge portion of the bulging portion, and the bracket is disposed so as to be sandwiched between the column and the shelf plate,
Since the abutting edge of the bulging portion is configured to abut on the side edge of the column, the lateral swing of the corner bracket is effectively prevented.

According to the corner bracket for an assembling shelf according to the sixth aspect, the corner bracket is formed symmetrically in a state of being bent at a right angle around the center line, so that the corner bracket is used. By doing
The corner bracket can be attached to the side plates of the shelf plate extending at right angles from the corner portion by a single attaching operation.

According to the corner bracket for an assembling shelf according to the seventh aspect of the present invention, the corner bracket is formed symmetrically in a state where the corner bracket is cut into two pieces at the center line, so that the corner bracket is perpendicular to the corner. The shelf plate can be connected to the column by using only one of the two side plates of the shelf plate extending in the direction of symmetry.

A triangle is formed by a line connecting the corners 3, and a wall surface of the corner bracket 3 is further provided outwardly from a portion corresponding to the hypotenuse of the triangle.

A second protruding portion 13 having an arcuate cross section is formed at the tip of the corner bracket 3 and protrudes outwardly when viewed from a plane. The second protruding portion 13 is used when the corner bracket 3 is assembled. The vertical dimension is set so that the upper and lower ends are fitted into the engagement holes 10 of the shelf 2. A lower portion of the corner bracket 3 has a bulging portion 15 which protrudes outward as a whole so as to have an abutting edge 18 which abuts on a lower edge portion of the side plate 8 of the shelf plate 2 at the time of assembling described later. Is formed. The outer surface of the bulging portion 15 forms a contact surface 18 ′ with the inner surface of the side wall 5 of the column 1.

At the intersection of the upper end portions of the two left and right plate members of the corner bracket 3, when assembling, which will be described later,
Protrusions 17 are provided which contact the intersections of the inner surfaces of the left and right side walls 5 of the column 1. And corner bracket 3
The upper edge portion is bent inward at a right angle so as to increase the contact area with the lower surface of the top plate 7 of the shelf plate 2. The edge is not limited to being bent inward at a right angle. Further, although the upper edge of the corner bracket 3 is normally brought into contact with the lower surface of the top plate 7 of the shelf 2, the upper edge does not have to be particularly brought into contact.

In order to form a prefabricated shelf by the above members, the inner surface of the side wall portion 5 of the column 1 and the side plate 8 of the corner portion of the shelf 2 are brought into contact with each other. The bracket 3 is provided, and the second protrusion 13 is fitted into the engagement hole 10 of the side plate 8, and the first protrusion 12 is fitted into the engagement hole 6 of the side wall 5. Then, the mounting bolt 4 is inserted into the engaging hole 6 of the column 1 located above the engaging hole 6 with which the first engaging portion 12 is engaged, the insertion hole 9 of the shelf board 2, and the insertion hole 11 of the corner bracket 3. At the same time, the contact edge 18 of the bulging portion 15 of the corner bracket 3 is brought into contact with the lower edge of the side plate 8 of the shelf board 2 for positioning, and the shelf board 2 and the column 1 are further aligned.

0, the upper part of the second protrusion 120 is connected to the side plate 8 of the shelf board 2.
And the upper end portion of the engaging hole 10 is abutted against the upper end portion of the engaging hole 10, whereby the solid connection between the column 1 and the shelf plate 2 through the corner bracket 3 of this embodiment can be obtained.

FIGS. 15 and 16 show a corner bracket 3 according to a further modification of the fifth example. FIG.
FIG. 14 is a perspective view of the corner bracket 3, and FIG. 14 shows a state where the corner bracket 3 is assembled. The corner bracket of this modified example is basically the same as that of the fifth example, except that it is located on the surface of the bulging portion 15 and substantially at the intermediate position between the insertion hole 11 and the first projection 12. First
The fourth example is different from the fifth example in that a fourth projection 121 similar to the projection is provided. The modification of the fifth example is characterized in that the fourth projection 121 is provided.

That is, by providing the above-mentioned fourth projection 121 on the bulging portion 15, the first bracket 121 is attached to the first projection as shown in FIG.
With the projection 12 engaged with the lower engagement hole 6, the fourth projection can be simultaneously engaged with the upper engagement hole 6, and as a result, the column 1 and the shelf 2 can be more reliably and firmly strengthened. And can be combined.

FIG. 17 is a sectional view taken along the line BB of FIG. As shown in this figure, the second projection 13 provided on the upper wall surface of the corner bracket has a tapered slope in the vertical direction as well as in the horizontal direction.

Since the root portion is set to be larger than the vertical width of the engaging hole 10 formed in the side plate 8 of the shelf 2, the second protrusion 13 is formed by the engaging hole 10. In the state where the second protrusion 13 has been fitted, the root portion of the second protrusion 13 does not reach the engagement hole 10, and the upper and lower outer edges of the second protrusion 13 abut against the upper and lower inner edges of the engagement hole 10. It is in a state. This also contributes to firmly assembling the corner bracket 3 to the column 1 and the shelf 2.

The configuration of the second protrusion 13 as described above is not limited to application to the modification of the fifth example, but can be applied to all other embodiments.

As described in detail above, the corner bracket 3 of the present invention has a triangular shape formed by a line connecting the insertion hole 11, the first projection 12 and the second projection 13 provided on the wall surface. Since the wall surface of the corner bracket is configured so as to be present more outward than the portion corresponding to the hypotenuse, even if a compressive force is applied such that the locking portions at both ends of the hypotenuse approach each other (ie, Even if a force that rattles the shelves is applied), there are walls on the hypotenuse,
It can sufficiently cope with the above-mentioned compression force. In other words, the corner bracket of the present invention is sufficiently and reliably
And the rattling of the shelf in the horizontal direction can be effectively suppressed.

A bulging portion 15 is formed at the center of the corner bracket 3, and the contact surface 1 provided on the bulging portion 15 is formed.
The corner bracket 3 is mounted in a state where the 8 ′ or the contact edges 14 and 18 are in contact with the inner surface or the side edge of the side wall 5 of the column 1 or the lower edge of the side plate 8 of the shelf 2. Therefore, when a moment is applied to rotate the shelf plate 2 and the corner bracket 3 with the installation portion of the mounting bolt 4 as a fulcrum according to the load of the article placed on the shelf plate 2 and the like, This moment can be effectively supported by the bulging portion 15 and the first protrusion 12.

Therefore, it is possible to sufficiently secure the support rigidity against the above-mentioned moment without fastening the above-mentioned connecting portion so strongly by the locking member composed of the above-mentioned mounting bolt 4, and when the above-mentioned moment or the like repeatedly acts. Also in this case, it is possible to reliably prevent rattling from occurring at the connecting portion between the corner bracket 3 and the column 1. Moreover, since the swelling portion 15 is provided, the rigidity of the corner bracket 3 itself against the moment load or the like can be improved. Therefore, even when a large load is input to the corner bracket 3, the corner bracket 3 is deformed. Can be effectively prevented.

In the above embodiment, the corner bracket 3
The first and second projections 12 and 13 projecting from the wall of
2 and the upper end of the corner bracket 3 with the engaging member formed of one mounting bolt 4 in the state of being engaged with the engaging hole 6 of the shelf 2 and the engaging hole 10 of the shelf board 2. Since the side plate 8 of the shelf 2 is configured to be integrally joined,
The time required for assembling the shelves can be greatly reduced without impairing the reinforcing effect of the connecting portion between the shelf plate 2 and the column 1.

That is, the load acting when an article is placed on the shelf 2 can be dispersed and supported by the mounting bolts 4 and the first and second projections 12 and 13. Despite the number of bolts 4 being reduced to one, almost the same connection strength as that obtained when the corner bracket is mounted using three mounting bolts is obtained, and the shelf is constructed with a simple configuration. The connection between the plate 2 and the column 1 can be effectively reinforced.

In the case of the corner bracket 3 shown in FIG. 11, there is an advantage that the corner bracket 3 can be shared and mass-produced.

In place of the first and second projections 12 and 13, as shown in FIG. 12, through holes 17 and 18 for mounting bolts 4 are formed at the lower end and the tip of the corner bracket 3. The corner bracket 3 may be joined to the connecting portion between the shelf plate 2 and the column 1 by the book mounting bolts 4.

In all of the above embodiments,
The mounting bolt 4 serving as a locking member is inserted into the engaging holes 6 and 61 of the column 1, the insertion hole 9 of the shelf 2, the insertion hole 11 of the corner bracket 3, and the like.
6, the mounting bolt 4 is tightened in a state where the nut 16 is screwed, and the support 1, the shelf 2 and the corner bracket 3 are fastened to each other. Except for the third example shown in FIG. 7, the insertion hole 11 of the corner bracket 3 itself is formed into a circular hole, a female screw is screwed into the circular hole, and the mounting bolt 4 is screwed into the circular hole to be fastened. You may make it. By doing so, the above-mentioned fastening with the mounting bolts 4 becomes possible even without the nut 16, so that the number of parts is reduced and this is convenient.

However, in the case of the third example shown in FIGS. 5 to 7, if a female screw is screwed into the insertion hole 9 of the shelf plate 2,
As described above, the fastening by the mounting bolt 4 is possible without the nut 16.

As described above, in the corner bracket of the present invention, the above-mentioned insertion hole or projection is arranged so that a triangle is formed by a line connecting the insertion hole or projection provided on the wall surface. However, since the wall surface of the corner bracket is formed so as to extend outward from a portion corresponding to the hypotenuse of the triangle, a compressive force is applied so that the locking portions at both ends of the hypotenuse approach each other. Also, there is a wall surface on the hypotenuse part, which can sufficiently cope with the above-mentioned compressive force, and as a result, it can sufficiently and surely function as a "haze", and the shelf board in the horizontal direction This is an epoch-making thing that can effectively suppress rattling.

When the corner bracket is formed with a bulging portion having a contact surface that comes into contact with the side wall of the column, the corner bracket is joined to the corner of the shelf from the inside of the side plate. Since the bulging portion is located in the gap formed between the outer surface of the wall surface of the corner bracket and the inner surface of the side wall portion of the column to fill the gap, the corner bracket and the column are in direct contact with each other, and the contact area As a result, the column and the shelf are connected more firmly.

When the corner bracket is formed with a bulged portion having an abutting edge for abutting the side plate of the shelf, the column and the shelf are joined via the corner bracket. Since the lower edge of the side plate of the shelf is supported by the abutting edge of the bulging portion, the shelf is supported by the column in a state where it is difficult for rattling to occur stably.

As described above, the bulging portion is formed in the corner bracket, so that the column and the shelf board are more firmly connected to each other via the corner bracket than in the related art, and the load of placing the article on the shelf board is increased. This is advantageous because sufficient support rigidity can be ensured.

A first projection engaged with an engagement hole formed in a side wall of the column on the wall surface of the corner bracket, and a second projection engaged with an engagement hole formed in a side plate of the shelf board. By forming the projection, the bolting can be omitted for this portion, and instead of six bolts for fastening at one corner of the conventional shelf, only two bolts can be used. As a result, the assembling work of the assembling shelf is extremely simplified, and the economic effect that can save labor and time is very large.

The bulging portion is formed so as to protrude outwardly over the entire lower surface of the wall of the corner bracket, and an abutting edge is formed at an upper edge portion of the bulging portion. When the side plate of the shelf is configured to be supported, the corner bracket is arranged on the inner surface of the corner of the side plate of the shelf, so that the entire lower surface of the corner bracket abuts on the inner surface of the side wall of the support. While the area is maximized, the shelves are supported by the upper edge of the bulging portion, and the columns and the shelves are connected more firmly, and the rattling of the shelves is more effectively suppressed. be able to.

The bulging portion is formed at the lower part of the wall surface of the corner bracket so as to protrude inward, and the contact edge is formed at the upper edge of the bulging portion. When the side plates of the plate are configured to be supported, rattling of the shelf is more effectively suppressed by arranging the corner brackets so as to be sandwiched between the column and the shelf.

The bulging portion is formed at the lower part of the wall surface of the corner bracket so as to protrude outward, and the abutting edge is formed at the side edge of the bulging portion. When the edge is configured to be in contact with the side edge of the column, the bracket is disposed so as to be sandwiched between the column and the shelf plate, so that the corner bracket can be effectively prevented from swaying.

When the corner bracket is formed symmetrically in a state of being bent at a right angle around the center line, the corner bracket can be used to attach the side plates of the shelf boards extending at right angles to each other from the corner portion at one time. The corner bracket can be attached by operation, which is convenient.

When the corner bracket is formed symmetrically in a state of being cut into two pieces at the center line portion, only one of the two side plates of the shelf plate extending at a right angle from the corner portion is symmetrical, and only one sheet is provided. Can be used to connect the shelf to the support, which is convenient.

Further, a third protrusion protruding outward is formed on the bulging portion, and the third protrusion is provided with the first protrusion and the second protrusion in both the vertical and horizontal directions. If the third protrusion is configured to abut on the side edge of the column when the corner bracket is mounted on the shelf, the corner bracket is mounted on the shelf. Since the third protrusion abuts on the side edge of the support post, an engaging member that penetrates the support hole, the insertion hole of the shelf side plate, and the insertion hole of the bracket is provided above the corner portion of the corner bracket. By tightening, the third
The protruding portion is in a state of strongly pressing the edge of the side wall portion of the column, so that a more secure and robust shelf board can be assembled.

Further, by strongly tightening the locking means, the corner bracket pivots around the third protrusion toward the locking means being tightened, so that the upper portion of the second protrusion is engaged with the shelf side plate. A state in which the column and the shelf are firmly abutted against the upper edge of the hole is also achieved, whereby the column and the shelf can be more securely and firmly connected.
