[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner bracket for an assembling shelf in which a shelf plate is detachably attached to a column.

[0002]

[Prior Art]

 In a normal assembly-type shelf, four pillars 21 made of angle steel are erected so as to be rectangular in plan view, and the four corners of a shelf plate 22 made of thin steel plate are fastened to these pillars 21 by bolts or the like. It is formed by supporting it.

Conventionally, as shown in FIG. 18, for example, a corner bracket 23 having bilaterally symmetrically bent surfaces and having a substantially triangular shape is provided between the support column 21 and the shelf plate 22. The upper end of the bracket 23 is placed between the side wall 24 of the column 21 and the side plate 25 of the shelf 22 to stop the bottle, and the tip and the lower end of the corner bracket 23 are attached to the side plate of the shelf 22. The corner bracket 23 reinforces the connecting portion between the shelf plate 22 and the column 21 by bolting to the side wall 24 of the column 25 and the column 21.

Further, as shown in FIG. 19, a pair of left and right symmetrically separated corner brackets 23 constitutes one set, and this one set is set to the side plate 25 of the shelf plate 22 and the support column as described above. There is also one that is interposed between the side wall portion 21 and 21.

That is, in the conventional assembling shelves as described above, by using the corner brackets as described above, it is possible to increase the contact area of the connecting portions between the shelves and the columns, so that it is easy. This structure has the advantage that this connecting portion can be effectively reinforced.

[0006]

However, since the shelf plate 22 and the support column 21 are basically connected only by bolting through the corner brackets 23, a considerably large number of bolts are required. It is important. The bolt holes at the various places where the bolts are inserted are usually long holes in order to flexibly adapt to the alignment.As a result, there is play in the tightened bolts and the bolts are tightened. However, the external force applied to the shelves causes the bolts to move in the play and tilt the shelves.

Therefore, in order to avoid such an inconvenience, the bolts are tightened extremely strongly, but the number of bolts is large, and therefore the assembling work of the shelf is complicated and requires a lot of time, Further, in the case of a shelf that is installed at a place where vibration occurs even if it is tightly tightened, this vibration causes a problem that the fastening force of the bolt is loosened and rattling occurs on the shelf plate.

Further, in the conventional corner bracket 23, the hypotenuse portion of the triangle formed by connecting the through holes formed in the wall surface for passing the bolt is cut out so as to be curved inward. Therefore, the effect of “glazing” was diminished, and the state was so-called “without triangle”, which is called in the terminology of those skilled in the art. Therefore, there is an inconvenience that the shelf plate 25 cannot be surely supported without rattling unless the corner bracket 23 has a considerable thickness.

The present invention has been made to solve the above problems, and easily and effectively reinforces the connecting portion between the shelf and the support with a simple structure, and the rattling of the connecting portion is prevented. It is an object of the present invention to provide a corner bracket for a prefabricated shelf that can effectively prevent the occurrence.

It is preferable that the upper edge portion of the corner bracket 3 is normally brought into contact with the lower surface of the top plate 7 of the shelf plate 2 in a state where the corner bracket 3 is attached to the gap between the shelf plate 2 and the column 1. , You don't have to contact us.

The concrete configuration of the corner bracket 3 according to the fourth example is not limited to the above-described one, and various modifications can be made. For example, as shown in FIG. Above the first protrusion 12 formed at the lower end, a second protrusion 13a protruding on the back surface side is formed, and on the side of the second protrusion 13 formed at the tip of the corner bracket 3. The corner brackets 3 may be formed symmetrically with respect to the center line X by forming the first protrusion 12a protruding on the front surface side. In this case, the corner brackets 3 having the same shape can be installed on each part of the shelf board 2.

Although not shown, the corner bracket 3 is not provided between the support column 1 and the shelf plate 2, but the side plate 8 of the shelf plate 2 is provided as in the first example. It can also be arranged from the inside. In this case, the second protrusion 13 should be projected outward (that is, provided on the front surface side like the first protrusion 12) and fitted into the engagement hole 10 of the side plate 8. I have to do it.

13 and 14 show a fifth example of the corner bracket for the assembling type shelf according to the present invention. 13 is an exploded perspective view showing a main part of an assembling type shelf assembled by the corner bracket according to the fifth example, and FIG. 14 is a side view of the same. As shown in these drawings, in the case of this example, the corner bracket 3 as a base is the one of the first example shown in FIG.

In the case of the corner bracket 3, the bulging portion 15 is formed with two third protruding portions 120 protruding in the up and down direction by cutting and pushing. The third protrusion is set to be located between the first protrusion 12 and the second protrusion 13 in both the vertical direction and the horizontal direction. Further, the third projection 120 is dimensioned so as to abut the side edge of the column in a state where the corner bracket 3 is assembled. In this example, two third protrusions 120 are formed, but the number is not particularly limited and may be one or three or more.

Therefore, when the corner bracket 3 is assembled to the assembling type shelf, the third protrusion 120 abuts on the side edge portion of the column, and the upper portion of the corner portion of the corner bracket 3 has an engaging portion of the column 1. By tightening the attachment bolt 4 as a locking member that penetrates the fitting hole 6, the insertion hole 9 of the side plate of the shelf plate, and the insertion hole 11 of the corner bracket 3, the third protrusion 120 causes the side wall portion of the column 1. The edge portion of 5 is strongly pressed, and the shelf plate can be assembled more reliably and firmly.

Further, when the mounting bolt 4 is strongly tightened, the corner bracket 3 is rotated around the upper third protrusion 120 in the direction of the mounting bolt 4 which is tightened, so that the upper portion of the second protrusion 120 is moved upward. The side plate 8 of the shelf plate 2 comes into a state of being stopped at the upper edge portion of the engaging hole 10 thereof, which also ensures the firm and firm coupling of the support column 1 and the shelf plate 2 via the corner bracket 3 of this example. Obtainable.

FIG. 15 and FIG. 16 show a corner bracket 3 which is a further modified example of the fifth example. FIG. 15 is a perspective view of the corner bracket 3, and FIG. 14 shows a state in which the corner bracket 3 is assembled. The corner bracket of this modified example is basically the same as that of the above fifth example, but on the surface of the bulging portion 15 and at a substantially intermediate position between the insertion hole 11 and the first protruding portion 12. This is different from that of the fifth example in that a fourth protrusion 121, which is similar to the first protrusion, is protrudingly provided. The modification of the fifth example is characterized in that the fourth protrusion 121 is provided.

That is, by providing the fourth protrusion 121 as described above on the bulging portion 15, the first protrusion 12 is provided downward as shown in FIG. 16 with the corner bracket 3 assembled. The fourth protrusion can be simultaneously engaged with the upper engagement hole 6 in the state of being engaged with the engagement hole 6, and as a result, the column 1 and the shelf board 2 can be more firmly and firmly coupled. Will be possible.

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

Since the root portion is dimensioned to be larger than the vertical width of the engagement hole 10 formed in the side plate 8 of the shelf plate 2, the second projection 13 is formed in the engagement hole 10 described above. In the state in which the second protrusion 13 is fitted in, the root portion of the second protrusion 13 does not reach the engagement hole 10, and the upper and lower outer edge portions of the second protrusion 13 contact the upper and lower inner edge portions of the engagement hole 10. It is in a stopped state. This is also useful for firmly assembling the corner bracket 3 to the column 1 and the shelf 2.

The above-mentioned configuration of the second protrusion 13 is not limited to the 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 protrusion 12 and the second protrusion 13 provided on the wall surface thereof. Since the wall surface of the corner bracket exists outwardly of the portion corresponding to the hypotenuse, even if a compressive force is applied such that the engaging portions at both ends of the hypotenuse approach each other ( That is, even if a force such that the shelf plate rattles is applied), the wall surface exists in the hypotenuse portion, and it is possible to sufficiently cope with the compression force. That is, the corner bracket of the present invention can sufficiently and surely perform the function of "glazing" and effectively suppress the rattling of the shelf in the horizontal direction.

Further, a bulging portion 15 is formed in the central portion of the corner bracket 3, and the abutting surface 18 ′ or the abutting edges 14 and 18 provided on the bulging portion 15 are connected to the inner surface of the side wall portion 5 of the column 1. Since the corner bracket 3 is configured to be attached in contact with the side edge portion or the lower edge portion of the side plate 8 of the shelf board 2, the loading load of the article placed on the shelf board 2 is set. When a moment that tries to rotate the shelf 2 and the corner bracket 3 acts on the installation portion of the mounting bolt 4 as a fulcrum, the moment is effectively generated by the bulging portion 15 and the first protrusion 12. Can be supported by.

Therefore, it is possible to sufficiently secure the supporting rigidity against the moment without the fastening member including the mounting bolt 4 tightening the connecting portion so strongly, and the moment and the like act repeatedly. Even in such a 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 rigidity of the corner bracket 3 itself against the moment load and the like can be improved by providing the bulging portion 15, the corner bracket 3 is deformed even when a large load is input to the corner bracket 3. It is possible to effectively prevent the occurrence of the situation.

In the above embodiment, the first and second protrusions 12 and 13 projecting from the wall surface of the corner bracket 3 are engaged with the engagement holes 6 of the support columns 12 and the engagement holes 10 of the shelf board 2. In this state, the side wall portion 5 of the support column 1, the upper end portion of the corner bracket 3 and the side plate 8 of the shelf plate 2 are integrally joined to each other by the engaging member composed of the single mounting bolt 4. The time required for assembling the shelves can be significantly reduced without impairing the reinforcing effect of the connecting portion between the column 2 and the column 1.

That is, since the load acting when an article is placed on the shelf board 2 can be dispersed and supported by the mounting bolt 4 and the first and second protrusions 12 and 13, Even though the number of mounting bolts 4 is reduced to one, approximately the same degree of connection strength can be obtained as when the corner bracket is mounted using three mounting bolts, and a simple structure is obtained. Thus, it is possible to effectively reinforce the connecting portion between the shelf board 2 and the column 1.

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 production thereof can be achieved.

Further, instead of the first and second protrusions 12 and 13, as shown in FIG. 12, insertion holes 17 and 18 of the mounting bolt 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 a book mounting bolt 4.

In all of the above-mentioned embodiments, the mounting bolt 4 as the locking member is provided with the engaging holes 6 and 61 of the column 1, the insertion hole 9 of the shelf 2, and the corner bracket 3. The nut 16 is screwed into the hole 11 or the like, and the mounting bolt 4 is tightened with the nut 16 being screwed to fasten the pillar 1, the shelf 2, and the corner bracket 3 to each other. However, except for the third example shown in FIGS. 5 to 7, the insertion hole 11 of the corner bracket 3 itself is a circular hole, and a female screw is screwed into the circular hole. The mounting bolt 4 may be screwed into this circular hole for fastening. By doing so, the above-mentioned fastening with the mounting bolt 4 can be performed without the nut 16, which is convenient because the number of parts is reduced.

However, in the case of the third example shown in FIG. 5 to FIG. 7, if a female screw is screwed in the insertion hole 9 of the shelf board 2, the mounting bolt 4 can be provided without the nut 16 as in the above. Can be concluded.

[Effect of the device]

 As described above, in the corner bracket of the present invention, the insertion holes or the protrusions are arranged so that the triangles are formed by the lines connecting the insertion holes or the protrusions provided on the wall surface thereof. Since the corner bracket wall faces outward from the portion corresponding to the hypotenuse, even if a compressive force is applied such that the locking parts at both ends of the hypotenuse approach each other, the hypotenuse Since there is a wall surface in the part, it is possible to sufficiently cope with the above compression force, and as a result, it is possible to perform the function of "glazing" sufficiently and surely, and the rattle of the shelf board in the horizontal direction. It is an epoch-making thing that can effectively suppress.

In the case where the corner bracket is formed with a bulging portion having an abutting surface that abuts against the side wall portion of the column, the corner bracket is joined to the corner portion of the shelf plate 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, the corner bracket and the column are in direct contact with each other, and the contact area Is increased, so that the column and the shelf are more firmly connected.

When the corner bracket is formed with a bulging portion having an abutting edge that comes into contact with the side plate of the shelf plate, in a state where the support column and the shelf plate are joined via the corner bracket. Since the lower edge portion of the side plate of the shelf plate is supported by the abutting edge of the bulging portion, the shelf plate is supported by the column in a state in which rattling hardly occurs in a stable manner.

As described above, since the bulging portion is formed on the corner bracket, the support pillar and the shelf board are more firmly connected to each other via the corner bracket, and the load for placing the article on the shelf board is increased. This is convenient because it is possible to sufficiently secure the supporting rigidity with respect to the like.

A first protrusion engaged with an engagement hole formed in the side wall of the column on the wall of the corner bracket, and a second protrusion engaged with an engagement hole formed in the side plate of the shelf plate. If a protrusion is formed, bolting can be omitted for this part, and it is possible to use only two fastening bolts, which conventionally required six fastening bolts on one corner of a shelf. As a result, the assembling work of the assembling shelves becomes extremely easy, and the labor and time can be saved accordingly, and the economic effect is very large.

The bulging portion is formed over the entire lower surface of the wall surface of the corner bracket so as to project outward, and a contact edge is formed at an upper edge portion of the bulging portion. If the side plate of the shelf is configured to be supported, by arranging this corner bracket on the inner surface of the corner of the side plate of the shelf, the entire lower surface of the wall of the corner bracket abuts the inner surface of the side wall of the support column, and While the contact area is maximized, the shelf is supported by the upper edge of the bulge, the posts and shelf are more firmly connected, and the rattling of the shelf is more effective. Can be deterred.

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

The bulging portion is formed on the lower portion of the wall surface of the corner bracket so as to project outward, and the abutting edge is formed on the side edge portion of the bulging portion. When the contact edge is configured to abut the side edge of the support column, the bracket is arranged so as to be sandwiched between the support column and the shelf plate, so that the lateral swing of the corner bracket is effectively prevented. ..

When the corner brackets are formed symmetrically while being bent at a right angle around the center line, by using the corner brackets, the side plates of the shelves extending from the corners at right angles to each other can be treated as a single object. It is convenient because the corner bracket can be attached by the mounting operation.

When the corner bracket is formed symmetrically in the 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 right angles from the corner portion is used as a single piece. It is convenient to use the stand alone to connect the shelves to the columns.

Further, a third protrusion protruding outward is formed on the bulge portion, and the third protrusion is provided with the first protrusion and the second protrusion in both the vertical direction and the horizontal direction. If the corner bracket is assembled, if the third protrusion is configured to abut the side edge of the column when the corner bracket is assembled to the shelf, the third bracket is arranged to be located between the corner bracket and the corner bracket. Since the third protrusion comes into contact with the side edge of the column, the engaging hole of the column, the insertion hole of the side plate of the shelf plate, and the insertion hole of the bracket penetrate through the upper portion of the corner portion of the corner bracket. By tightening the stop member, the third protrusion strongly presses the edge of the side wall of the support column, so that the shelf plate can be assembled more reliably and firmly.

Further, when the locking means is strongly tightened, the corner bracket is rotated around the third protrusion in the direction of the locking means, so that the upper part of the second projection is engaged with the shelf side plate. The upper edge portion of the dowel hole is strongly stopped, which also allows the support column and the shelf plate to be more firmly and firmly connected.
