Description

  The present invention relates to an assembly shelf that is assembled by being coupled so that a plurality of plate members can be attached and detached.

  An assembly shelf that can increase the number of plates to be used and add the number of stages has been developed (see Patent Document 1). This assembly shelf is fixed by sandwiching shelf boards with upper and lower support columns. In order to connect the upper and lower columns, screws penetrate the shelf up and down. The upper end of the screw is screwed into a female screw provided at the lower end of the column disposed on the shelf board, and the lower end is screwed into the female screw provided at the upper end of the column. In this assembly shelf, the number of shelves can be increased to increase the number of steps.

In the assembly shelf having this structure, the number of steps can be increased or decreased by the number of shelf plates connected vertically. However, since the shelf boards cannot be connected horizontally, there is a drawback that the width of the assembly shelf cannot be changed. An assembly shelf that connects the shelves horizontally has also been developed. This assembly shelf connects the shelf boards up and down using connectors of various structures. For this reason, there are disadvantages that the types of connectors used for connecting the shelf boards up and down increase, and the number of parts used increases. Further, it is necessary to adjust the type and number of connectors to be used depending on the number of steps and the width of the assembly shelf.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies an assembly shelf for embodying the technical idea of the present invention, and the present invention does not specify the assembly shelf as follows.

  Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

  In the assembly shelf shown in FIGS. 1 to 5, a plurality of cross board units 1 are connected vertically and horizontally so as to have the required number of steps and width. Further, the assembly shelf of FIG. 4 has a predetermined depth by connecting the cross board unit 1 to the front and rear.

  The cross board unit 1 constituting the assembly shelf is obtained by connecting a horizontal board 2 and a vertical board 3 so as to be orthogonal to each other at the center. The horizontal plate member 2 and the vertical plate member 3 are provided with a slit 4 extending in the lateral direction, which is a direction perpendicular to the side surface 5, from one side surface 5 toward the other side surface 5. The horizontal plate 2 and the vertical plate 3 shown in the figure have a slit 4 at the center of both end faces 6. Further, the horizontal plate 2 and the vertical plate 3 shown in the figure extend from one side surface 5 to the center of both side surfaces 5 and are provided with slits 4.

The horizontal plate member 2 and the vertical plate member 3 are inserted into the slit 4 and connected in a cross shape to form the cross plate unit 1. The slit 4 has the width of the slit 4 of the horizontal plate 2 equal to the thickness of the vertical plate 3 and the width of the slit 4 of the vertical plate 3 equal to the thickness of the horizontal plate 2 so that the plate can be inserted without any gap. ing. The vertical plate 3 is inserted into the slit 4 of the horizontal plate 2, the horizontal plate 2 is inserted into the slit 4 of the vertical plate 3, and the horizontal plate 2 and the vertical plate 3 are connected at right angles so as to be detachable. Unit 1 is assumed.

  Furthermore, the slit 4 can provide the recessed part 9 in the opposing surface 4A which mutually opposes, as shown in FIG. The slit 4 shown in the drawing is provided with a recess 9 along the slit 4 in the central portion excluding the outer peripheral portion of the facing surface 4A. FIG. 7 is an enlarged cross-sectional view showing a state in which the horizontal plate 2 is connected to the vertical plate 3 having the slit 4 of this structure. The vertical plate 3 shown in these drawings is provided with a recess 9 at the center of the facing surface 4A of the slit 4, and both side edges of the facing surface 4A are used as support portions 10 for sandwiching the horizontal plate 2 and the horizontal plate 2 A plane portion parallel to the surface of the substrate is provided. As shown in FIG. 7, the slit 4 has an interval (L) between the support portions 10 that is the opening width of the slit 4 equal to the thickness (D2) of the horizontal plate 2 and an interval between the central portions of the opposing surface 4A ( H) is made larger than the thickness (D2) of the horizontal plate 2. Since the slit 4 having this structure sandwiches the horizontal plate 2 with the support portion 10 which is the opening edge of the slit 4 without any gap, the horizontal plate 2 inserted into the slit 4 of the vertical plate 3 can be firmly attached without play. Can be linked to. Further, the slit 4 prevents the central portion of the opposing surface 4A from contacting the horizontal plate 2 by the recess 9 provided in the central portion of the opposing surface 4A. 3 has a feature that it can be inserted into the slit 4 and smoothly connected.

  The recess 9 provided in the slit 4 has a depth (d) of 0.1 mm or more, preferably 0.1 to 0.5 mm, and effectively prevents the central portion of the facing surface 4A from contacting the horizontal plate 2. it can. The recess 9 shown in the figure has a U-shaped cross-section, but the recess can be V-shaped or curved. The recesses having these shapes can have the maximum depth within the above-described range. Further, the width (W) of the concave portion 9 provided in the slit 4 is set to 1/5 to 4/5, preferably 1/3 to 4/5, of the thickness (D3) of the vertical plate member 3, that is, The width (T) is set to 1/10 to 2/5, preferably 1/10 to 1/3, of the thickness (D3) of the vertical plate 3, and the horizontal plate 2 inserted into the slit 4 of the vertical plate 3 is free of play. It can be firmly connected in the absence.

  The vertical plate 3 shown in FIG. 7 is a plate having a flash structure in which the surface plate 12 is fixed to the surface of the core 11. The vertical plate 3 having this structure is provided with slits having an opening width (L) in the surface plates 12 on both sides, and the core material 11 disposed between the surface plates 12 has an opening width (H) larger than (L). ), And the concave portion 9 is formed on the facing surface 4A of the slit 4. In such a flash-structured plate material, the surface plate 12 can extremely reduce expansion and contraction and expansion in a direction parallel to the surface of the plate material, but the core material 11 can expand and contract in the direction parallel to the surface of the plate material. Expansion increases. For example, when the core material expands and the central portion of the opposing surface of the slit expands, the expanded core material portion comes into contact with the plate material inserted into the slit, the resistance increases, and smooth connection cannot be achieved. Further, when the central portion expands and protrudes, the plate member inserted into the slit cannot be held without play. On the other hand, the structure in which the concave portion is provided in the core material portion can absorb the expansion of the core material portion in the concave portion and effectively prevent the core material portion from contacting the plate material inserted into the slit. The plate material inserted into the slit can be held without play while the plate material is inserted in a low resistance state and smoothly connected. However, this plate material does not necessarily need to open the entire slit provided in the core material wider than the slit of the surface plate to be a recess, and a recess may be provided in the central portion of the facing surface of the slit provided in the core material. it can. Furthermore, the horizontal plate and the vertical plate are made of a low-resistance state between the horizontal plate and the vertical plate by providing a recess on the opposite surface of the slit even in a wooden plate other than the flash structure or a plate made of a material other than wooden. Needless to say, they can be connected and held without play.

  6 and 7 show a state in which a concave portion 9 is provided in the slit 4 of the vertical plate member 3 and the horizontal plate member 2 is inserted into the slit 4. Furthermore, a recess 9 can be provided in the slit 4 of the horizontal plate 2 with the same structure as in FIGS. 6 and 7, and the vertical plate 3 can be inserted into the slit 4. In particular, the recess 9 provided in the slit 4 can be connected to each other in the most ideal state by providing the recess 9 in both the horizontal plate 2 and the vertical plate 3. However, the recessed part of a slit can also be provided only in any one of a horizontal board | plate material and a vertical board | plate material.

  The horizontal plate member 2 and the vertical plate member 3 are a wooden plate member, a plate member having a flash structure in which the plate member is fixed to the surface of the core member, or a metal plate or a plastic plate. The horizontal plate member 2 and the vertical plate member 3 are plate members having an outer shape of 400 mm × 400 m and a thickness of 26 mm. However, the outer shape can be changed within a range of 5 cm to 50 cm, for example, and can be made smaller or larger than this in order to use it for various purposes and make it an optimum value for the purpose. The thickness of the horizontal plate member 2 and the vertical plate member 3 is thicker than 5 mm, preferably thicker than 10 mm, more preferably thicker than 15 mm. Since the horizontal plate member 2 and the vertical plate member 3 are provided with the connecting holes 8 for inserting the connecting dowels 7 in the end surfaces 6 and the side surfaces 5, the connecting holes 8 can be provided in the end surfaces 6 and the side surfaces 5 and have sufficient strength. In addition, the thickness is determined according to the application and size.

  The horizontal plate member 2 and the vertical plate member 3 can be plate members having the same outer shape and thickness. Since the cross board unit 1 can use the same plate material and can have the same shape in both the vertical and horizontal directions, it can be conveniently used by freely changing the horizontal direction and the vertical direction. However, the horizontal plate member 2 and the vertical plate member 3 can have the same width and different lengths, and can also have different thicknesses. The horizontal plate material and the vertical plate material having different thicknesses can increase the load resistance to be placed on the horizontal plate material by increasing the thickness of the horizontal plate material. Alternatively, the vertical plate material can be increased to increase the load resistance in the vertical direction.

  The horizontal plate member 2 and the vertical plate member 3 constituting the cross plate unit 1 are provided with a plurality of connecting holes 8 at predetermined intervals on both end faces 6 in order to insert the connecting dowels 7. As shown in FIGS. 4 and 5, the horizontal plate member 2 and the vertical plate member 3 can connect the adjacent cross plate unit 1 to the side surface 5 by providing a connection hole 8 in the side surface 5 as well as the end surface 6. .

  The connection hole 8 is provided from the end surface 6 or the side surface 5 toward the inside in a posture orthogonal to the end surface 6 or the side surface 5 and parallel to both surfaces of the plate material. The connection hole 8 can be formed in a columnar shape, a polygonal columnar shape, or an elliptical columnar shape. However, the cylindrical connection hole 8 can be easily provided, and can be connected by inserting a cylindrical connection dowel 7. The connecting hole 8 has a sufficient strength with an outer diameter of, for example, 3 mm or more, preferably 4 mm or more, and more preferably 5 mm or more. The connecting hole 8 is, for example, 10 mm or less, preferably 9 mm or less, more preferably 8 mm or less. This is because if the connecting hole is too large, the strength of the portion provided with the connecting hole is lowered.

  The connecting dowel 7 is inserted into the connecting hole 8. The connecting dowel 7 is connected to the connecting hole 8 so as not to easily come off. One end of the connecting dowel 7 is inserted into the connecting hole 8 of one cross plate unit 1 and the other end of the connecting dowel 7 is inserted into the connecting hole 8 of the other cross plate unit 1 disposed adjacent thereto. The cross board units 1 arranged adjacent to each other are connected horizontally by connecting horizontal plate members 2 via connecting dowels 7 inserted into the connecting holes 8 and vertically connected by connecting vertical plate members 3. .

  The connecting dowel 7 is a wooden cylinder whose outer periphery is chamfered. The connecting dowel 7 can be inserted by tapping lightly into the connecting hole 8, and is manufactured to a thickness that can be pulled out of the connecting hole 8 by grasping with a pliers or the like. If the connecting dowel is too thick, it cannot be smoothly inserted into the connecting hole. On the other hand, if the connecting dowel is too thin, the connecting dowel can be easily removed and the horizontal plate or vertical plate cannot be connected firmly. When the wooden connecting dowel 7 is press-fitted into the connecting hole 8, the surface is pressed by the inner surface of the connecting hole 8 and becomes thin. In this state, the connecting dowel 7 inserted into the connecting hole 8 is pressed against the inner surface of the connecting hole 8 by an elastic restoring force and connected so as not to come off. The connecting dowels 7 are not limited to wood, but can be made of, for example, hard plastic or metal.

  In the cross board unit 1, a connecting dowel 7 is inserted into the connecting hole 8 in the end face 6 of the horizontal board 2 to connect the adjacent cross board unit 1 in the horizontal direction, and to the connecting hole 8 in the end face 6 of the vertical board 3. By inserting the connecting dowel 7, the cross board unit 1 can be connected in the vertical direction. The number of cross-plate units 1 connected horizontally is adjusted to make the horizontal width the optimum width, and the number of cross-plate units 1 connected vertically is adjusted to optimize the overall height.

  Furthermore, the cross board unit 1 inserts the connection dowel 7 in the connection hole 8 of the side surface 5 of the horizontal board | plate material 2 and the vertical board | plate material 3, and connects the side surfaces of the adjacent cross board unit 1 as shown in FIG. You can also. This assembly shelf can be adjusted to the optimum length by adjusting the number of cross plate units 1 connected in the front-rear direction.

  Furthermore, the cross board unit 1 in which the connection holes 8 are provided in the side surfaces 5 of the horizontal plate material 2 and the vertical plate material 3 does not necessarily have to be connected to each other, as shown in FIG. It is also possible to connect the end surface 5 of the adjacent cross board unit 1. This assembly shelf can connect, for example, a plurality of cross board units connected vertically and horizontally, with the directions of each shelf crossing each other, so that the creativity of the entire assembly shelf can be improved and its configuration and design can be improved. It can be further diversified.
