2. Description of the Related Art FIG. 15 shows an example of a conventional assembly type shelf.
In FIG. 15, reference numeral 1 denotes a column, reference numeral 2 denotes a shelf attached to the column 1, and reference numeral 3 denotes a cylindrical body fixed to a corner of the shelf 2. The shelf 2 is composed of a column 3
17 and FIG. 1 previously mounted on the support 1.
The cylindrical body 3 is supported on the column 1 via a sleeve 4 as shown in FIG.

As shown in FIG. 16, a shelf plate 2 is formed by connecting a pair of upper and lower frames 5 and 6 having a rectangular shape as a whole so as to be separated from each other in a vertical direction by a substantially corrugated reinforcing wire 7. The tubular body 3 is fixed to the corners of the frames 5 and 6. Further, wires 8, 9 are laid on the upper frame 5 so as to be orthogonal to each other, and the wires 8, 9 allow articles to be placed on the shelf 2. Also,
The column 1 has a columnar shape, and a plurality of grooves 10 around the column 1 are formed on the surface thereof at equal intervals along the longitudinal direction of the column 1.

As shown in FIG. 17, the sleeve 4 is made up of resin-made sleeve halves 4A and 4B having a semi-cylindrical shape. These sleeve halves 4A, 4B
Before being mounted on the support 1, it is divided into two parts, and when mounted on the support 1, the support 1 is sandwiched from both sides to be assembled into a cylindrical shape. Opposite side ends of the sleeve halves 4A, 4B are engaged with each other when the sleeve halves 4A, 4B are assembled, so as to prevent a displacement between the sleeve halves 4A, 4B. A projection 4a and a recess 4b for engagement are formed respectively.

Further, on the inner surfaces of the sleeve halves 4A and 4B, there are formed ridges 4c which engage with the grooves 10 of the support column 1. In addition, the outer peripheral surface of the sleeve 4 is formed in a conical shape whose diameter increases from one end to the other end, as shown in FIG. That is, in FIG.
0, the outer diameter of one end of the sleeve 4 is d1, and the outer diameter of the other end is d2.
Then, (d0 <d1 <d2).

The cylindrical body 3 has a cylindrical shape having a through hole 3A at the center, and the inner peripheral surface of the through hole 3A corresponds to the outer peripheral surface of the sleeve 4 as shown in FIG. 5
Side) to the other end (the frame 6 side). That is, the inside diameter of one end of the through hole 3A is d1, and the inside diameter of the other end is d2.

When assembling the shelf, first, the column 1 is sandwiched between the sleeve halves 4A and 4B from both sides at the position where the shelf plate 2 is to be mounted, and the ridge 4c is inserted into the groove 10 as shown in FIG. Engage. As a result, the sleeve 4 is mounted around the column 1, and the movement of the sleeve 4 along the longitudinal direction of the column 1 is prevented by the engagement between the groove 10 and the ridge 4c.

Next, the support 1 is inserted into the through hole 3A so that one end of the sleeve 4 and the other end of the cylindrical body 3 face each other, and then the support 1 is moved so that one end of the sleeve 4 faces upward. And as shown by an arrow S in FIG.
Then, the shelf 2 is moved downward. Here, since the inside diameter of the other end of the through hole 3A is d2 and the outside diameter of one end of the sleeve 4 is d1, when the cylindrical body 3 is moved downward, the through hole 3A is Attached from. Moreover, the outer peripheral surface of the sleeve 4 has a conical shape whose diameter increases toward the other end,
In addition, since the inner peripheral surface of the cylindrical body 3 corresponds to the outer peripheral surface of the sleeve 4, the inner peripheral surface of the cylindrical body 3 and the outer peripheral surface of the sleeve 4 come into close contact with each other, and Further downward movement is prevented.

In this state, since the sleeve 4 is pressed inward from the cylindrical body 3, the engagement between the groove 10 and the ridge 4c is further strengthened. As a result, the tubular body 3 is supported at a desired position on the column 1 via the sleeve 4.

Then, this operation is performed almost simultaneously with the cylindrical body 3 fixed to the corner of the shelf 2, whereby the lowermost shelf 2 is attached to the column 1. Further, the same operation is repeatedly performed, and the shelves 2 are attached to the columns 1 sequentially from the lower side, whereby a shelf as shown in FIG. 15 is completed.

[0011]

By the way, in this type of shelf, after assembly, the shelf 2 is detached from the column 1 for the purpose of changing the position of the shelf 2 or adding or removing the shelf 2. There are cases. However, since the shelf 2 is supported by the column 1 by inserting the cylindrical body 3 fixed to the corner into the column 1, the shelf 2 is located above the mounting position of the shelf 2.
Is attached, it is necessary to remove all the shelf boards 2 and the sleeves 4 above the position from the support column 1. As a result, there is a problem that the attaching / detaching operation becomes complicated and the operation takes time. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to enable easy and quick mounting and dismounting of a shelf plate with respect to a column on which a shelf plate or the like is mounted.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. The members having the same structure as the conventional assembly type shelf shown in FIGS. The same reference numerals as those in FIGS. 15 to 18 denote the same parts, and a description thereof will be omitted.

The shelf according to the present invention comprises:
A collar 11 removably supported on the sleeve 4;
A holder 12 detachably supported by the collar 11 and the sleeve 4, the collar 11, and the holder 12,
And a shelf 13 removably supported by the column 1.

Examples of the structure of the collar 11 are shown in FIGS. 1 to 4 are an upper perspective view, a top view, a side view, and a cross-sectional view of the collar 11, respectively. Color 11
Is a metal such as aluminum or polycarbonate or A
It is a member having a rectangular parallelepiped shape as a whole, which is integrally formed of a resin such as BS, and has a fitting hole 11A formed in the center thereof so as to penetrate the collar 11 along four parallel sides thereof. As shown in FIG. 4, the inner peripheral surface of the fitting hole 11A is formed in a tapered shape corresponding to the outer peripheral surface of the sleeve 4 so as to increase in diameter from one end (the upper end in FIG. 4) to the other end. The inside diameter of one end of the fitting hole 11A is d1, and the inside diameter of the other end is d2.

The collar 11 has a slit-shaped opening 11B formed by cutting out the side surface of the fitting hole 11A toward one of the ridges along the four sides of the collar 11. Here, the width W of the opening 11 </ b> B is set to be larger than the outer diameter of the column 1 and smaller than the maximum outer diameter of the sleeve 4. On the other hand, the fitting hole 11 of the collar 11
The ridge portion located on the opposite side of the opening 11B formation side across A is a semicircular shape as viewed from the end, as indicated by reference numeral 11C, for the purpose of suppressing unnecessary overhang when the shelf is assembled. It is a chamfered part.

Further, in the side surface of the collar 11, the opening 1
1B are recessed inward except for the other end, and as a result, the other end of these side surfaces has a step (projection) 11D protruding outward from the recessed side.
Are formed along the other edge of the collar 11, respectively. Also, these stepped portions 11D go around the chamfered portion 11C side beyond the ridge line portion connected to the side surface, and as a result, on the chamfered portion 11C side of these ridge line portions, concave portions formed by retreating these ridge line portions inward. 11E are respectively formed.

FIG. 5 shows an example of the structure of the holder 12 and the shelf 13.
And FIG. The holder 12 is formed by attaching a metal plate to the step 11D.
Are bent in an L-shape according to the shape of the end face, and convex portions 12A are formed at both ends thereof in directions (inward) facing each other in accordance with the shape of the end face of the recess 11E. . The width h2 from one end (the upper end in FIG. 5) to the other end of the holder 12 is determined from one end of the collar 11 to the step 11D.
And the thickness and side shape of the metal plate forming the holder 12 are determined when the holder 12 is supported by the collar 11 as described later.
The side surface of the step 11D and the side surface of the holder 12 are set to be the same.

The holder 12 has a corner 12 of a shelf 13 having a structure similar to that of the conventional shelf 2 and, instead of the cylindrical body 3, a space 12B sandwiched between the projections 12A is directed outward. The projections 12 </ b> A are fixed so that the extending direction is orthogonal to the plate surface of the shelf 13.

Next, assembling of the shelf having the above configuration will be described with reference to FIGS. When assembling the shelf, first, as in the case of assembling the conventional shelf, the sleeve half 4 is placed at the position where the shelf plate 13 is to be attached.
A and 4B sandwich the support 1 from both sides, engage the protrusions 4c in the grooves 10, and wrap the sleeve 4 around the support 1,
The support 1 is erected so that one end of the sleeve 4 faces upward. This state is shown in FIG.

Next, above the position where the sleeve 4 is mounted, the collar 11 is supported from the outside (left side in the figure) with the one end thereof facing upward and the opening 11B facing the support 1 side. 1 and the fitting hole 11A is mounted around the support 1 from the side through the opening 11B. In this case, since the width W of the opening 11B and the minimum diameter d1 of the fitting hole 11A are both larger than the outer diameter d0 of the support 11, the passage of the opening 11B to the support 11 and the mounting of the fitting hole 11A are both performed. Easy.

After the fitting hole 11A is mounted around the column 1, the collar 11 is moved downward along the column 1. As a result, as in the case of the above-described conventional cylindrical body 13, at the position where the inner peripheral surface of the fitting hole 11A and the outer peripheral surface of the sleeve 4 are closely attached to each other,
Further downward movement of the collar 11 is prevented, and the collar 1
1 is supported on the sleeve 4. This state is shown in FIG.
In this case, since the width W of the opening 11B is smaller than the maximum outer diameter d2 of the sleeve 4, the sleeve 4 does not come off from the opening 11B.

When the collar 11 is supported by the sleeve 4,
Above the mounting position of the sleeve 4, the shelf 13 to which the holder 12 is fixed is placed on the space 12 </ b> B with the space 12 </ b> B formed between the protrusions 12 </ b> A of the holder 12 facing the column 1.
Is approached from inside (right side in the figure) to the column 1 until the column overlaps with the column 1. Further, when the space 12B overlaps with the column 1, the protrusions 12A formed at both ends of the holder 12 are respectively engaged with the recesses 11E of the collar 11, and the lower end of the holder 12 contacts one end surface of the step 11D. The shelf 13 is moved downward along the column 1 until it comes into contact. This state is shown in FIGS.

In the state shown in FIGS. 9 to 11, the lateral movement of the holder 12 is prevented by the engagement between the convex portion 12A and the concave portion 11E and the contact between the opposing side surfaces of the collar 11 and the holder 12. The downward movement of the holder 12 is prevented by the contact between the lower end of the holder 12 and one end surface of the step 11D. That is, in this shelf, the holder 12 is placed on the step 11D and the collar 11
It is firmly and detachably supported.

Then, the above-mentioned operation is performed on each of the columns 1 erected at the corners of the shelf 13 sequentially or almost simultaneously as needed, so that the shelf 13 is attached to the column 1. Further, the same operation is repeatedly performed, and the shelf 13 according to the present embodiment is completed by attaching the shelf plate 13 to a desired position of the column 1. To remove the shelf 13, the reverse operation may be performed.

In the case of the shelf of the present embodiment, the shelf 1
Since the members (sleeve 4, collar 11, and holder 12) required for mounting 3 are all detachable from the side of the support 1, the support 1 on which another shelf board 13 or the like is mounted is mounted on the support 1. However, the shelf 13 can be attached and detached without removing the upper shelf 13 and the like. Therefore, according to the shelf of the present embodiment, it is possible to easily and quickly attach and detach the shelf plate 13 to and from the column 11 on which another shelf plate 13 and the like are attached. Workability in expansion, removal, replacement, etc. is improved.

Also, since the components (post 1, sleeve 4, etc.) constituting the conventional shelf shown in FIGS. 15 to 18 can be diverted, the type and the number of components to be newly created for implementing the present invention Requires less. Further, by simply purchasing the collar 11 and the shelf 13, the shelf 13 can be added to the conventional shelf having the shelf 2 having the tubular body 3 </ b> A without disassembling the shelf, or the shelf 13 can be added. The plates 2 and 13 can be used in combination.

In addition, since the holder 12 is supported by the collar 11 with the collar 11 sandwiched from the left and right with the opening 11B interposed therebetween, the opening 1
Even if the collar 11 is deformed in the direction to open the 1B out,
This deformation is prevented by the holder 12. Therefore, the shelves 13 do not fall off the columns 1 due to the deformation of the collar 11. Also, with the outward deformation of the collar 11 due to the load, the side surface of the collar 11 strongly presses the opposite side surface of the holder 12 from the inside. The engagement between 11 and holder 12 is strengthened.

In addition, in the case of the shelf of the present embodiment, the holder 1
2 is fixed to the shelf 13 and is firmly supported by the column 1 via the collar 11 and the sleeve 4. Therefore, the strength of the shelf 13 itself is high, and the same high load resistance as the conventional shelf 2 having the tubular body 3 can be obtained, and the lateral movement or deformation of the column 1 due to the load is prevented. , Shelf 1
3 and the holder 12 fixed to the shelf 13, the mounting of the shelf 13 has the effect of improving the strength of the entire shelf.

The holder 12 can be engaged with the collar 11 from either one end or the other end.
2 is selectively engaged with the collar 11 from one end or the other end (whether one end or the other end is directed downward), so that the front and back of the shelf 13 can be selectively moved upward or downward. Can be used for For example, in the example shown in FIGS. 9 to 11, the frame indicated by reference numeral 5 is located at the upper side, but by replacing the top and bottom of the shelf 13 and engaging the holder 12 with the collar 11,
The frame indicated by reference numeral 6 can be positioned above.

Further, as described above, the width h2 from one end to the other end of the holder 12 is different from the one end of the collar 11 to the step 11D.
When the thickness and the side surface shape of the metal plate forming the holder 12 are supported by the collar 11, the side surface of the step portion 11D and the side surface of the holder 12 Are set to be on the same plane. As a result, when the holder 2 is supported by the collar 11, unnecessary gaps, steps, and the like are not formed between the collar 11 and the holder 12, and a shelf excellent in aesthetic appearance can be obtained.

On the other hand, for example, as shown in FIG. 12, the holder 12 is separate from the shelf plate, and the frames 5 and 6 as shown in FIG. A shelf board having a bent corner C may be detachably engaged with the shelf board. In this case, after the holder 12 is locked to the collar 11, it protrudes inward of the shelf,
By engaging the corner C of the shelf 13A from above with the hook 12C that is bent upward, the shelf 13A is detachably supported by the holder 12.

Alternatively, for example, a support (supporting means) 14 for supporting the shelf 13A as shown in FIG. 13 may be prepared, and the holder 12 may be fixed to both ends of the support 14. The support body 14 is an elongated member that is roughly composed of a side plate 14A and a bottom plate 14B and has an L-shape as viewed from the end. The holder 12 has bottom plates 14B at both ends of the side plate 14A.
The direction of extension of the convex portion 12A is
4 are fixed so as to be orthogonal to the longitudinal direction. Further, an upper stopper 14 is provided at the center of the side plate 14A.
C protrudes from the side end surface of the side plate 14A so as to face the bottom plate 14B, and from both ends of the bottom plate 14B, an end stopper 14
D project toward the upper stopper 14C so as to face each other.

At the time of mounting the shelf plate 13A, the holders 12 fixed at both ends are respectively engaged with the collars 11 supported on the support columns 1 via the sleeves 4, so that the holders 12 are erected at the corners of the shelf. A pair of supports 14 are horizontally and parallel supported between the four columns so that the bottom plate 14 faces downward and projects inward on the shelf. By mounting the frame 6 of the shelf 13A on the bottom plate 14B of the pair of supports 14, the shelf 13A is detachably supported between the pair of supports 14.

When the shelf 13A is mounted between the supports 14, for example, as shown by reference numeral A in FIG. 14, the shelf 13A is held at one end stopper 14D side.
The shelf plate 13A is inserted obliquely from above between the supports 14 through a gap formed between the upper stopper 14C and the end stopper 14D, and the shelf plate 13A is pushed between the supports 14 along the bottom plate 14B. As a result, as indicated by reference numeral B in FIG. 14, the shelf plate 13A is placed horizontally on the bottom plate 14B. Further, the longitudinal movement of the support 14 of the shelf 13A placed on the bottom plate 14B is prevented by the end stopper 14D, and the vertical movement of the shelf 13A is prevented by the bottom plate 14A.
B and the upper stopper 14C. On the other hand, when removing the shelf 13A, the above operation may be performed in reverse.

In these examples, the holder 12 is mounted on the shelf 13A.
, The holder 12 and the shelf 13A do not contribute to the strength of the entire shelf, and the load resistance of the shelf 13A is slightly lower than that of the shelf indicated by reference numeral 13. Further, in these examples, since the column 1 cannot be supported on the shelf 13A, the column 1 is previously erected by a shelf that can support the column 1 as indicated by reference numeral 2 or 13, for example. There is a need. Other functions and effects are the same as in the case where the shelf indicated by reference numeral 13 is used.

It should be noted that the specific shape and the like of each member constituting the shelf according to the present invention is not limited to the above-described embodiment, but can be appropriately changed without departing from the spirit of the present invention. Needless to say.

[0042]

As described above, in the shelf of the present invention, since all the members required for attaching the shelf board to the column are detachable from the side of the column, another shelf board or the like is mounted upward. The shelf can be attached to and detached from the column to which is attached without removing the upper shelf or the like. Therefore, according to the shelf of the present invention, it is possible to easily and quickly attach / detach the shelf plate to / from a column on which another shelf plate or the like is attached.
