Description

  The present invention relates to a shelf board and an assembly shelf for an assembly shelf, and more particularly, to a wire shelf board in which wires such as metal wires are assembled in a grid or mesh shape and joined by welding or the like, and an assembly shelf using the same.

  2. Description of the Related Art Conventionally, assembling shelves using wire shelves in which wires such as metal wires are assembled in a lattice or net shape and joined by welding or the like have been widely used for both home use and business use. The basic structure is such that four long cylindrical posts having engagement grooves formed at predetermined intervals on the outer peripheral surface are engaged with the engagement grooves of the four long cylindrical posts. A plurality of shelf plate supporting fittings (supporting sleeves) each having a pair of short semi-cylindrical bodies (also referred to as sleeve halves) each having an engaging projection on its inner peripheral surface and having its outer peripheral surface expanded downward. ), And a wire shelf board in which wires each having four cylindrical receiving portions expanding downward at four corners are assembled in a lattice shape and joined together, and the shelf boards are provided at desired positions of the four long cylindrical supports. A wire shelf having a desired number of steps is provided by fitting the support fitting and fitting the cylindrical receiving portions at the four corners of the wire shelf into the fitted shelf support fitting. It can be assembled as an assembly shelf (for example, see Patent Literature 1 and Patent Literature 2).

  Assembly shelves using such wire shelves have the advantages of high structural rigidity, excellent load-bearing performance, and easy assembly and easy handling, as well as various designs and sizes. Variations of shelves are prepared in advance (for example, see Patent Literature 3 and Patent Literature 4), and an assembly shelf having a desired size and design and a desired number of shelves can be assembled using these shelves. , Very convenient.

  However, even if various kinds of shelves are prepared in advance, for example, if shelves of different sizes are prepared for every 1 cm, an extremely complicated and enormous amount of product lineup is required. Manufacturing costs are also high, and there are also difficulties in exhibiting places at dealers.In addition, it is too complicated for consumers who purchase them, and they are confused by the choice. It is not realistic to prepare a shelf board in advance. On the other hand, the location where the actual assembly shelves are installed can be located in various places such as homes and workplaces, so it is often a little short or long depending on the installation location. Become.

Here, a telescopic pipe shelf in which large and small pipes having different diameters are slidably connected is known (for example, see Patent Document 5 and Patent Document 6), but assembling using a wire shelf plate. Since the basic structure is greatly different from that of the shelf, it is impossible to apply this as it is. In addition, it is not preferable that excellent advantages such as high rigidity, load bearing performance, ease of assembly, and the like be impaired by making the wire shelf plate flexible.
JP-A-5-176816 Japanese Utility Model Registration No. 3095668 Japanese Patent No. 1084820 Design Registration No. 1123906 Japanese Utility Model Laid-Open No. 2-119047 Japanese Utility Model Publication No. 6-20422

  The present invention has been made in view of the above-described problems, and has a desired effect without impairing excellent advantages such as high rigidity, load-bearing performance, and ease of assembly of a wire shelf plate and an assembly shelf for an assembly shelf. It is an object of the present invention to provide a telescopic wire shelf for an assembling shelf and an assembling shelf that can be freely extended and contracted in size.

  In order to solve the above problems, the telescopic wire shelf for an assembly shelf according to the present invention includes a rectangular frame wire, a grid wire laid vertically and horizontally on the frame wire, and one end of the frame wire. A cylindrical receiving portion provided at two corners in contact with the lower end and a lower portion disposed substantially parallel to and spaced downward from three ends of the frame wire contacting the cylindrical receiving portions at the two corners; A wire, a corrugated wire alternately abutting on the lower wire and the frame wire, and a U-shaped or V-shaped or U-shaped or V-shaped section having an upper open end provided on the inner surface of the opposing lower wire. A first shelf member including a pair of slide rail portions having a U-shape and a fixture attached to the slide rail portion, and a rectangular frame wire having a width corresponding to the slide rail portion of the first shelf member. A grid-like wire laid vertically and horizontally on the frame wire; A cylindrical receiving portion provided at two corners in contact with the other side end of the material and having a downwardly enlarged diameter, and spaced substantially parallel downward from a three-side end of the frame wire contacting the cylindrical receiving portion at the two corners; A second shelf member provided with a lower wire disposed at a height corresponding to the slide rail portion of the first shelf member, and a corrugated wire alternately contacting the lower wire and the frame wire; By making the opposing lower wires of the second shelf member slidable on the slide rail portion of the first shelf member and being fixable by a fixture at a desired position, the length of the shelf plate can be expanded and contracted. It is characterized by having done.

  That is, the wire shelf is separated into a first shelf member and a second shelf member, a slide rail portion is provided on the first shelf member, and the second shelf member is slidable by the slide rail portion. This makes the length of the shelf board flexible. Thus, the wire shelf can be made expandable and contractible, so that the size can be adjusted according to the installation location of the assembly shelf. In addition, since the basic structure of the conventional wire shelf and the cylindrical receiving portion and the like remain unchanged, the advantages of the conventional wire shelf are not impaired, and the handling is the same, so that the versatility is high.

  It is preferable that a reinforcing wire is laid horizontally between the pair of slide rail portions. For small shelves, it is not always necessary, but for medium to large shelves, the rigidity of the slide rail, which is the joint between the first shelf member and the second shelf member, is increased, and the load-bearing performance is improved. Can be increased. Further, the length of the slide rail portion is not particularly limited, but preferably has a length of, for example, about 2/3 of the total length of the first shelf member. Even if it is longer than this, there is no particular inconvenience, but if it is too long, it becomes a useless part and looks bad. Even if it is shorter than this, there is no particular disadvantage, but if it is too short, it is disadvantageous in terms of rigidity and load bearing performance.

  It is preferable that each of the wires is a metal wire. Because it is excellent in rigidity and most common. In addition, the fixing tool is not particularly limited as long as it can fix the opposing lower wire of the second shelf member to the slide rail portion of the first shelf member, but from the viewpoint of manufacturing cost and easiness of the structure, The screw is preferably screwed to the lower end surface of the slide rail.

  In addition, the telescopic assembly shelf of the present invention includes four long cylindrical posts on which engagement grooves are engraved at predetermined intervals on the outer peripheral surface, and engagement grooves of the four long cylindrical supports. A plurality of shelf plate supporting fittings each comprising a pair of short semi-cylindrical bodies (sleeve halves) each having an engaging ridge on an inner peripheral surface so as to engage with the outer peripheral surface and having an outer peripheral surface expanded downward. (Supporting sleeve) and the telescopic wire shelf according to the present invention, and a shelf support fitting is fitted at desired positions of the four long cylindrical pillars, and the fitted shelf is fitted. By fitting each of the cylindrical receiving portions of the telescopic wire shelf into the plate supporting fitting, it is possible to assemble a shelf having a desired number of shelves, and to make the length of the shelf flexible. It is characterized by having done. Thus, the size of the entire assembly shelf can be adjusted according to the installation location of the assembly shelf.

  ADVANTAGE OF THE INVENTION According to this invention, the assembly shelf which can be extended and contracted to a desired size, without impairing the high rigidity of a wire shelf board for assembly shelves, the load-carrying performance, and the ease of assembly, etc. The present invention has a great effect that it is possible to provide a telescopic wire shelf and an assembly shelf for use.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but it goes without saying that various changes or modifications can be made to these embodiments without departing from the technical idea of the present invention.

FIG. 7 is a plan view (a) and a bottom view (b) of FIG. 8 is a front view showing the second shelf member, and FIG. 9 is a plan side view (a) and a bottom view (b) of FIG. FIG. 10 is a perspective view showing the telescopic assembly shelf of the present invention. In each of the drawings, reference numeral 2 denotes a telescopic wire shelf for an assembly shelf of the present invention, reference numeral 4 denotes a first shelf member, reference numeral 6 denotes a second shelf member, and reference numeral 50 denotes a telescopic assembly shelf of the present invention. . In the following description, the case where each wire is a metal wire is described, but a hard plastic or the like may be used as long as the shelf is a small shelf. The thickness of each wire is not particularly limited, but is, for example, about 2 mm to 6 mm in diameter.

  As shown in FIGS. 1 to 4, the retractable wire rod shelf 2 for an assembly shelf of the present invention is configured by combining a first shelf member 4 and a second shelf member 6, and a first shelf. The plate member 4 has cylindrical receiving portions 8a and 8b at one of two corners, and the second shelf plate member 6 has cylindrical receiving portions 8c and 8d at the other two corners. Like the plate, four corners are provided with cylindrical receiving portions 8a, 8b, 8c, 8d.

  As is well shown in FIGS. 5 to 7, the first shelf board member 4 is formed by arranging a plurality of grid-like wires 22 a and 22 b in a grid (or mesh) in the vertical and horizontal directions of the rectangular frame wire 20. A shelf is formed. Cylindrical receiving portions 8a and 8b are welded to two corners in contact with one side end of the rectangular shelf, that is, two longitudinal left corners of the rectangular frame wire 20. The cylindrical receiving portions 8a and 8b have a shape whose diameter is expanded downward as in the conventional case, and are portions fitted into the shelf board supporting fittings 55 (supporting sleeves) as shown in FIG. is there.

  The three side ends in contact with the cylindrical receiving portions 8a, 8b, that is, the portions of the wire members 20a, 20b, 20c located at the three side ends of the rectangular frame wire member 20, are separated downward and substantially parallel to the rectangular frame wire member 20. Are provided with lower wires 24a, 24b, 24c. Also, between the lower wires 24a, 24b, 24c and the corresponding wires 20a, 20b, 20c of the rectangular frame wire 20 thereabove, the corrugated wires 26a, 26b, 26c are alternately contacted with both. Are welded. The portion constituted by the lower wires 24a, 24b, 24c and the corrugated wires 26a, 26b, 26c is also called a reinforcing bridge, and is a portion for ensuring the rigidity and load-bearing performance of the wire shelf.

The lower wire and the corrugated wire do not exist in the portion of the wire 20d existing on the side ends other than the three side ends in the rectangular frame wire 20. This is because, as will be described later, since the portion serves as a storage opening for the second shelf member 6, it must be left open. Therefore, as shown in FIG. 5, the lower wire 24 a is bent at the right end in the longitudinal direction and is welded to the rectangular frame wire 20. The same applies to the lower wire 24b opposed to the lower wire 24a.

  A pair of slide rails 10a, 10b are welded to the inner surfaces of the opposing lower wires 24a, 24b among the lower wires 24a, 24b, 24c. The slide rail portions 10a and 10b are elongated members having a U-shaped or U-shaped cross section with the upper end being an open end. It should be noted that the shape may be V-shaped as long as the upper end is an open end. The length of the slide rail portions 10a and 10b is not particularly limited, but is, for example, about 2/3 of the total length of the first shelf member 4. There is no particular inconvenience if it is longer or shorter, but if it is too long, it is useless and looks bad. Conversely, if it is too short, it is disadvantageous in terms of rigidity and load bearing performance.

  Further, between the slide rail portions 10a and 10b, (four in the illustrated example) reinforcing wire members 28 are suspended. This is for increasing the rigidity of the slide rail portions 10a and 10b, which are the joining portions of the first shelf member 4 and the second shelf member 6, to enhance the load-bearing performance. The number of the reinforcing wires 28 is not particularly limited, and the reinforcing wires 28 may be omitted as long as they are small shelves, or about 0 to 10 depending on the length of the slide rails 10a and 10b and the required rigidity. It may be increased or decreased as appropriate.

  Further, a fixture is attached to the slide rail portions 10a and 10b. This is for fixing the second shelf plate member 6 to the slide rail portions 10a, 10b. In the illustrated example, the screw 12 that is screwed to the lower end surfaces of the slide rail portions 10a and 10b is shown as a fixing device from the viewpoint of manufacturing cost and ease of structure, but other clips or the like may be used as long as they can be fixed.

  As shown in FIG. 8 and FIG. 9, the second shelf board member 6 is formed by arranging a plurality of grid-like wires 32 a and 32 b in a grid (or mesh) in the vertical and horizontal directions of the rectangular frame wire 30. A shelf is formed. Cylindrical receiving portions 8c and 8d are welded to two corners in contact with the other end of the rectangular shelf, that is, two corners on the right side in the longitudinal direction of the rectangular frame wire 30. The cylindrical receiving portions 8c and 8d have a shape whose diameter is expanded downward as in the prior art, and are portions to be fitted into the shelf board supporting fittings 55 (supporting sleeves) as shown in FIG. is there.

  Here, the rectangular shelf in the second shelf member 6 needs to have a width corresponding to the slide rails 10a and 10b of the first shelf member 4, so that the rectangular frame wire 30 is The width is several cm smaller than the rectangular frame wire 20 of the shelf 4. For example, when the width of the rectangular frame wire 20 of the first shelf member 4 is about 46 cm, the width of the rectangular frame wire 30 of the second shelf member 6 is about 44 cm. Therefore, in consideration of the balance of the four corners when the telescopic wire shelf 2 is viewed as a whole, the welding positions of the cylindrical receiving portions 8a and 8b with respect to the rectangular frame wire 20 of the first shelf board member 4 are determined. The welding position of the cylindrical receiving portions 8c and 8d with respect to the rectangular frame wire 30 of the two-shelf plate member 6 is slightly different. That is, while the rectangular frame wire 20 of the first shelf member 4 is welded at the outermost periphery of the cylindrical receiving portions 8a and 8b (see FIG. 7), the rectangular frame wire of the second shelf member 6 is welded. Numeral 30 is a portion slightly inner than this and is welded to the cylindrical receiving portions 8c and 8d (see FIG. 9). Thereby, the four corners of the telescopic wire rod shelf 2 when viewed as a whole are rectangular instead of trapezoidal (see FIG. 3).

  The three side ends in contact with the cylindrical receiving portions 8c, 8d, that is, the portions of the wire members 30a, 30b, 30d located on the three side ends of the rectangular frame wire member 30 are separated downward and are substantially parallel to the rectangular frame wire member 30. Are provided with lower wires 34a, 34b, 34d. Also, between the lower wires 34a, 34b, 34d and the corresponding wires 30a, 30b, 30d of the rectangular frame wire 30 thereabove, the corrugated wires 36a, 36b, 36d are alternately contacted with both. Are welded. The portion composed of the lower wires 34a, 34b, 34d and the corrugated wires 36a, 36b, 36d is also referred to as a reinforcing bridge, and is a portion for ensuring the rigidity and load-bearing performance of the wire shelf. The lower wire rods 34a and 34b and the corrugated wire rods 36a and 36b joined to the lower rail rods 34a and 34b are slidably accommodated in the slide rails 10a and 10b of the first shelf member 4 described above. For example, when the height from the slide rails 10a, 10b to the rectangular frame wire 20 in the first shelf member 4 is about 3 cm, the second shelf member 6 The height from the lower wires 34a, 34b to the rectangular frame wire 30 is about 2 cm.

  It should be noted that there is no lower wire or corrugated wire in the portion of the wire 30c located on the side end other than the above-mentioned three ends in the rectangular frame wire 30. This is because it is a part to be stored in the first shelf member 4 and needs to be left open. Therefore, as shown in FIG. 8, the lower wire 34 a has a bent portion 34 a 1 at the left end in the longitudinal direction and is welded to the rectangular frame wire 30. The same applies to the lower wire 34b opposed to the lower wire 34a.

  Then, the first shelf member 4 and the second shelf member 6 configured as described above are combined to constitute the telescopic wire shelf 2 for the assembly shelf of the present invention. That is, as shown in FIGS. 1 to 4, opposed lower wires 34 a and 34 b of the second shelf member 6 and corrugated wires 36 a to be joined thereto are provided on the slide rail portions 10 a and 10 b of the first shelf member 4. , 36b are slidably accommodated, and screws 12 serving as fixing devices are screwed in and fixed at desired positions, so that the length of the shelf plate can be extended and contracted. This makes it possible to adjust the size according to the installation location of the assembly shelf. For example, the length can be reduced as shown in FIG. 3, or the length can be reduced as shown in FIG. It can be in a stretched state.

  Next, the telescoping assembly shelf 50 of the present invention is an assembling shelf using the telescoping wire shelf 2 for the assembling shelf of the present invention. The difference from the conventional assembly shelf is that the telescopic wire shelf 2 for the assembly shelf of the present invention is used, and the other configuration is the same as the conventional assembly shelf. Although detailed description of the portion is omitted, as shown in FIG. 10, four long cylindrical pillars 52 having engagement grooves 53 formed at predetermined intervals on the outer peripheral surface thereof are A pair of short semi-cylindrical bodies (sleeve half) having engagement ridges on the inner peripheral surface so as to engage with the engaging grooves 53 of the long cylindrical pillars 52 and having an outer peripheral surface whose diameter is expanded downward. ), A plurality of shelf support members 55 (supporting sleeves) are fitted at desired positions, and the shelves for supporting the shelf according to the present invention are mounted on the fitted support members 55 for shelf support. By fitting the cylindrical receiving portions 8a, 8b, 8c, 8d at the four corners of the wire shelf 2 respectively, the shelf having a desired number of steps is provided. It is possible to assemble the shelf, but which may be telescopic to shelf plate length. According to the telescopic assembly shelf 50 of the present invention, the size can be adjusted according to the installation location of the assembly shelf, and the handling such as assembly is the same as that of the assembly shelf using the conventional wire shelf, Since the rigidity and load bearing performance are not inferior, it is extremely convenient.
