(57) [Summary] [Purpose] Shelf plates are detachably installed on the left and right side plates of the storage shelf, and the shelf plates are securely fixed to the side plates to strengthen the storage shelf, and the side plates are deformed to the outside. To prevent. A shelf plate fixture having a protrusion formed in a direction orthogonal to an axis of the through hole on an outer surface near one end of a cylindrical body having a through hole for a fastening screw.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixture for a shelf board in a storage shelf.

[0002]

[Prior art]

 A top plate and a bottom plate are screwed to the left and right side plates to form a frame body, and a back plate is fitted in a groove formed around the rear side of the frame body. The wooden built-in type storage shelves that are vertically installed have a pair of front and rear dowel holes vertically spaced on the inner wall corresponding surfaces of the left and right side plates, and the dowel tips are inserted into the desired dowel holes. However, the shelf board was supported on the four dowels protruding from the inner wall surface of the side board.

However, the above method of supporting the shelf plate is easy to attach and detach, but since the shelf plate is not connected to the side plate, the strength of the storage shelf cannot be improved, and the left and right side plates are not connected. In the case of a vertically long storage shelf, if the shelf in the middle position is bent downwards due to the weight of the stored items on the shelf, or the dowel in the middle position is pushed by the shelf plate on which the heavy items are placed. When it is tilted downward due to this, an outward force acts on the dowel at that position. As a result, the middle part of the left and right side plates was bent outwards, the shelf plate in that part was disengaged from the dowel, and the stored items were sometimes dropped.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned problems of the shelf fixing device, the present invention makes it easy to attach / detach the shelf, and securely connects the left and right side plates to the shelf to enhance the strength of the storage shelf. In addition, the purpose is to prevent the shelf plate from coming off the side plate by eliminating the outward deformation of the side plate.

[0005]

[Means for Solving the Problems]

 The shelf fixing device of the present invention has a protrusion formed on the outer surface of the tubular body provided with the through hole for the fastening screw at one side thereof in a direction orthogonal to the axis of the through hole. A recess for receiving the head of the fastening screw may be formed at one opening end of the through hole in the fixture.

[0006]

[Action]

 In the shelf plate fixing device according to the present invention, when the tips of the fastening screws inserted into the through holes are screwed into the dowel holes formed in the left and right side plates of the storage shelf, the cylindrical body is projected upward. Then, it is fixed in front of and behind the both side plates. By stacking the shelves on this cylinder and fitting the notch vertical holes formed in the four corners into the protrusions and the cylinder into the lateral grooves, the shelf is supported without sliding forward and the vertical holes The fitting with the protrusions prevents the left and right side plates from being deformed to the outside and strengthens the storage shelf.

When the recess for receiving the head of the fastening screw is formed at one opening end of the through hole as in claim 2, the head of the fastening screw does not project from one side of the tubular body, and therefore the notch is formed. The shape of the part becomes simple and the drilling work becomes easy.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of a fixture for a shelf board according to the present invention, in which a through hole 3 for a fastening screw 2 is provided at the center of a cylindrical body 1 made of plastic, and the outer side of the cylindrical body 1 on one side is provided. A protrusion 4 is integrally formed on the surface in a direction orthogonal to the axis of the through hole 3. A recess 6 for receiving the head 5 of the fastening screw 2 is formed at one opening end of the through hole 3.

In the wooden assembling storage shelf shown in FIG. 2, a vertically long frame body 10 is formed by a top plate 8 and a bottom plate 9 at both upper and lower ends of both left and right side plates 7, and a back side is provided at the rear side of the frame body 10. The plate 11 is fitted. A pair of front and rear dowel holes 12 are formed at regular intervals on the inner wall surface of the left and right side plates 7. Reference numerals 13 and 14 denote shelves, and L-shaped notches 17 are formed at the left and right ends of the shelves 13 at positions facing the front and rear dowel holes 12 and each of which has a lateral groove 15 and a vertical hole 16 orthogonal thereto. Is formed. Recesses 19 that engage with the dowels 18 are formed in the left and right ends of the shelf plate 14 at positions facing the front and rear dowel holes 12.

In the above-described embodiment of the present invention, as shown in FIG. 3, if the tips of the fastening screws 2 penetrating the through holes 3 are screwed into the four dowel holes 12 in the left and right side plates 7, respectively. The cylinder 1 is fixed to the inner wall surface of the side plate 7. In this case, the head 5 of the fastening screw 2 fits within the recess 6. The shelves 13 are placed on the four cylinders 1 fixed to the shelves 7 in this way, and the vertical holes 16 of the notches 17 formed at the four corners are fitted into the protrusions 4, respectively, and the lateral grooves 15 are formed. When fitted on the cylindrical body 1, the shelf plate 13 is installed between the left and right side plates 7 and is securely connected to the both side plates 7. Further, this shelf plate 13 is easily detached from both side plates 7 by pushing it up from below, and the cylinder body 1 is also easily detached from both side plates 7 by removing the fastening screws 2.

[0011]

【effect】

 Since the shelf plate fixing device according to the present invention has the above-mentioned structure, the fastening screw is inserted into the through hole of the cylindrical body, and the tip of the fastening screw is inserted into the dowel holes of the left and right side plates with the protrusion facing upward. The cylindrical body can be reliably and easily fixed to the inner wall surfaces of both side plates by simply screwing them together, and can be easily separated from the both side plates.

When the shelves are stacked on the four cylinders fixed to the left and right side plates, and the vertical holes of the notches formed at the four corners of the shelves are used as the protrusions and the lateral grooves are fitted on the cylinders, Is supported without sliding forward, and by fitting the vertical holes and the protrusions, the downward bending of the shelves and the outward deformation of the left and right side plates are prevented. It can be prevented and a robust storage shelf can be constructed. Also, this shelf plate can be easily detached from the cylindrical body by pushing it up from the lower side and detached from both side plates.

When the recess for receiving the head of the fastening screw is formed at one opening end of the through hole as in the second aspect, the shape of the notch becomes simple and the boring operation becomes easy.
