It can be used as a board.
Utility Model Registration No. 3114095

  However, this type of structure is all applied to a rectangular panel in the past. Panels constructed using such a core material have a good finish, high texture and strength, and have excellent effects such as not making a cheesy sound when an object collides. In the case of the body, it is usual practice to join the steel material by welding or the like and finish it to the shape, and there is a problem that the weld marks and the seams between the steel materials deteriorate the appearance quality and the texture. . Moreover, if the whole is constituted by aluminum die casting in order to solve this problem, it becomes extremely expensive.

  The present invention pays attention to such a problem, and aims to realize a non-rectangular structure with a sandwich structure of a core material and a metal plate, thereby solving the problems described.

  In order to achieve this object, the present invention takes the following measures.

  That is, the furniture panel according to the present invention is configured by sandwiching the left and right sides of the core member with metal plates, facing the core member, and facing the metal plate in a direction orthogonal to the sandwiching facing of the metal plate. A member is disposed opposite to the core member, and a part of the reinforcing member is protruded in a predetermined direction from the main body including the core member, and the metal plate is extended along the protruding portion. In addition, the metal plate is deformed so as to substantially cover the outer periphery of the reinforcing member and the core member.

  If comprised in this way, since the base end of the reinforcement member which forms the protrusion part enters in a main-body part, and is integrally pinched | interposed with a metal plate with a core material etc., it is an unusual panel body which has such a protrusion part. Even if there is, the projecting part is integrated with the main body part to obtain strength, and the part exposed to the outer surface is a surface that is almost continuous from the metal plate to the region from the main body part to the projecting part and their outer peripheral end faces. It wraps around and presents a good appearance with a texture.

  As an effective structure for further developing the shape of the protruding portion, the reinforcing member of the protruding portion protruded from the main body portion has another reinforcing member disposed opposite to the reinforcing member, and one set of the reinforcing members The thing which has arrange | positioned the core material also in between is mentioned.

  In order to appropriately perform pressure bonding and use it for improving the appearance, it is desirable to secure a slight clearance between the bent portions of the left and right metal plates facing each other by deformation.

  In order to properly arrange the reinforcing members, etc., which are internal elements, without damaging the outer shape of the panel body, the bent portions of the left and right metal plates facing each other by deformation function as at least a reinforcing member positioning means. It is desirable.

  In order to effectively increase the strength of the main body while securing the protruding state of the reinforcing member, the reinforcing member is provided at a position surrounding the end surface of the core material from four directions, and a part of the reinforcing member is provided from the main body portion including the core material. It is preferably provided in a state protruding in a predetermined direction.

  In order to increase the surface accuracy of the portion corresponding to the boundary portion between the reinforcing member and the core material on the surface of the metal plate, at least a part of the reinforcing member has an inward U-shape that opens to the core material side. The inner edge of the side wall arranged at a position continuous to both sides of the side wall is further bent, and the bent piece is closely attached to the end surface of the core material, so that the boundary portion between the side wall of the reinforcing member and the side surface of the core material is provided. It is effective to avoid positioning of the edge of the reinforcing member.

  In order to accommodate the various panel body outlines while ensuring strength with the reinforcing member, the part where the appearance forms a straight line when viewed from the direction perpendicular to the panel surface, including the panel body and protrusions, is U-shaped. The bottom wall is arranged along the straight line using the reinforcing member, and the non-linear appearance is given to the leading edge of the side wall using the U-shaped reinforcing member. It is effective.

  In order to cope with more complex shapes, the area between the bent portion of the metal plate covering the main body portion and the bent portion of the metal plate covering the protruding portion is narrowed with respect to the intersection of the main body portion and the protruding portion. It is effective to make it continue through an intermediate bent part with a deformed part such as a punched-out portion.

  In order to make this furniture panel body correspond to various usage patterns, it is desirable to configure the entire left and right metal plates to be mirror-symmetric.

  In order to achieve both weight reduction and strength improvement, and to suppress the occurrence of abnormal noise, it is preferable that the core material is a lightweight core material such as a paper honeycomb.

  Since the present invention has the above-described configuration, when a furniture panel body is formed by sandwiching the left and right sides of the core material with a reinforcing member together with a metal plate, the panel shape having a protruding portion at a part thereof has a texture and panel strength. Thus, it is possible to provide a new and useful furniture panel body that can pursue various furniture having a structure that has not been conventionally used in the office furniture field.

  At that time, a slight clearance between the bent portions 16a-16a, 16b-16b, 16c-16c, 16d-16d, 16e-16e, and 16f-16f of the pair of steel plates 16, 16 after pressure bonding. The steel plate 16 having a required dimension is used so that the Further, the bent portion 16c of the steel plate 16 covering the protruding portions 2 and 3 from the bent portion 16e of the steel plate 16 covering the main body portion 1 with respect to the crossing portion of the main body portion 1 and the protruding portions 2 and 3 shown in FIG. , 16d (parts corresponding to the corners 1x and 1y) have a relatively large curvature. Therefore, as shown in FIG. 8, there are deformed portions 61a and 62a such as a hollow portion as well as drawing. It is made continuous via the intermediate bent portions 61 and 62.

  Since the bending is performed using a predetermined mold, the bending position is determined, and the bent portions 16a to 16f shown in FIG. 2 are bent while the reinforcing members 11, 12, 13, and 14 are accommodated therein. It functions as these positioning means, and the core member 15 is also indirectly positioned inside the reinforcing members 11, 12, 13, 14 by this. For use as positioning means, a bent portion is formed on one steel plate 16, and reinforcing members 11, 12, 13, and 14 are arranged in a positioned state, and then the other steel plate 16 is covered to form a bent portion. It can also be implemented by the technique of doing. As described above, the structure of the panel body including the left and right steel plates 16 and 16 is all left-right symmetric.

  As shown in FIG. 9, the panel body of the present embodiment configured as described above has a main body portion 1 as a leg side plate, an upper protruding portion 2 as a stay portion, a lower protruding portion 3 as a base portion, a desk or the like. It can be used as a U-shaped leg constituting furniture with a top board. An adjuster 3z is attached to the lower protrusion 3 using the reinforcing member 14d shown in FIG. 2, and the top plate 4 is attached to the upper protrusion 2 using the reinforcing members 13, 13d, and 13e shown in FIG.

The top plate 4 is fixed to the projecting portion 2 by being moved relative to 2y, and the back plate 5 is fixed to the hook holes 5y and 5z provided on the front surface of the fixed claw 1y and the movable claw 1z. The back plate 5 is fixed to the main body 1 by moving the movable claw 1z relative to the fixed claw 1y at that position. Will be.

  Since the panel body A is symmetrical in the thickness direction, the same panel body A can be used for the left and right legs 1 and 1 shown in FIG. 10, and also shown in FIG. 11 when forming a facing top plate surface. Thus, the same panel bodies A and A can be arranged back to back on the front and rear legs 1 and 1.

  As described above, when the panel body A of the present embodiment is configured by sandwiching the left and right surfaces of the core material 15 with the pair of steel steel plates 16, the panel body A faces the core material 15 and is orthogonal to the sandwiching facing of the steel plates 16. The reinforcing members 13 and 14 made of steel are opposed to each other through the core member 15 so as to face each other, and a part of the reinforcing members 13 and 14 protrudes from the main body 1 including the core member 15 in a predetermined direction. The steel plate 16 is extended along the protruding portions 2 and 3 and the steel plate 16 including the extended portion is deformed so as to substantially cover the outer periphery of the reinforcing members 13 and 14 and the core material 15. .

  With this configuration, the base ends of the reinforcing members 13 and 14 forming the projecting portions 2 and 3 enter the main body portion 1 and are integrally sandwiched by the steel plate 16 together with the core material 15 and the like. Even if it is the unusual panel body A which has the various protrusion parts 2 and 3, the protrusion parts 2 and 3 are united with the main-body part 1, and intensity | strength is acquired, and the steel plate 16 from the main-body part 1 is the part exposed to an outer surface. In order to wrap the region extending from the projecting portions 2 and 3 and the outer peripheral end faces thereof with a substantially continuous surface, the space between the main body portion 1 and the projecting portions 2 and 3 is particularly completed with no welding marks or joints. The protrusions 2 and 3 from the main body 1 are in a flush state including the curved shapes of the corners 1x and 1y, and a good appearance with a high texture is exhibited. If the edge cover 100 or the like continuous from the main body portion 1 to the projecting portions 2 and 3 is mounted using the slit as shown in FIG. A high furniture panel A can be constructed.

  In this case, a slight clearance is provided between the bent portions 16a-16a, 16b-16b, 16c-16c, 16d-16d, 16e-16e, 16f-16f of the left and right steel plates 16 facing each other due to deformation. Therefore, when pressing and adhering, the right and left steel plates 16 and 16 are preferentially pressed against the core material 15 and the reinforcing members 11, 12, 13, and 14 to ensure an interview Can be worn.

  The bent portions 16a, 16b, 16c, 16d, 16e, and 16f of the left and right steel plates 16 and 16 that face each other due to the deformation not only cover the outer peripheral positions of the main body 1 and the protruding portions 2 and 3, but also the folded portions. Since the curved portions 16a, 16b, 16c, 16d, 16e, and 16f can be used as a positioning reference for the reinforcing members 11, 12, 13, 14, etc., the reinforcement that is an internal element without deteriorating the outer shape of the panel body A Appropriate arrangement of the members 11, 12, 13, 14, etc. can be made.

  The reinforcing members 11, 12, 13, and 14 are provided at positions that surround the end face of the core material 15 from four directions, and some of the reinforcing members 13 and 14 protrude from the main body 1 including the core material 15 in a predetermined direction. Since the reinforcing members 11, 12, 13, and 14 surround the core 15 in a frame shape, and the steel plate 16 is integrally sandwiched between the reinforcing members 11, 12, 13, and 14 to constitute the main body portion 1, the protruding of the reinforcing members 13 and 14 The strength of the main body 1 can be effectively increased while securing the state.

  In this case, at least the reinforcing members 11 and 12 shown in FIG. 3 have an inward U-shape that opens toward the core material 15, and the inner edges of the side walls 11 a and 12 a arranged at positions continuous with both surfaces 15 a of the core material 15 are Further, the bent pieces 11c and 12c are further closely attached to the end face 15b of the core member 15, and the reinforcing members 11 and 12c are attached to the boundary portions between the side walls 11a and 12a of the reinforcing members 11 and 12 and the side surface 15a of the core member 15. Since twelve edges 11z and 12z are avoided from being positioned, this contributes effectively to improving the appearance quality.

  That is, when the edges 11z and 12z of the reinforcing members 11 and 12 and the core material 15 are adjacent to each other as shown in FIG. In FIG. 4, lines along the edges 11z and 12z are likely to appear on the surface of the steel plate 16 due to the hard and sharp edges 11z and 12z of the reinforcing members 11 and 12, but the bent portions 11c as shown in FIG. If 12c is formed, the boundary portion with the core material 15 has a smooth round shape (R), and thus the influence on the surface of the steel plate 16 can be effectively reduced. The reinforcing members 13 and 14 of this embodiment are not formed with bent portions adjacent to the core material 15, but it goes without saying that it is effective to form the same bent portions in these portions. Yes.

  Further, as shown in FIG. 2 and the like, the panel body 1 and the protrusions 2 and 3 including the panel body 1 and the part whose appearance is a straight line when viewed from the direction perpendicular to the panel surface (the upper surface of the upper protrusion 2 serving as the stay part). The front and back end face portions of the main body portion 1 serving as the portion and the leg side plate) are arranged with the bottom walls 13b, 14b, 11b, 12b along the straight line using the U-shaped reinforcing members 13, 14, 11, 12; A portion in which the appearance is non-linear (a corner portion 1x between the upper projecting portion 2 serving as a stay portion and the main body portion 1 serving as a leg side plate, a lower projecting portion 3 serving as a base portion, and a main body portion 1 serving as a leg side plate The corners 1y and the like are provided with the non-linear shape on the end edges 13a1 and 14a1 of the side walls 13a and 14a using U-shaped reinforcing members 13 and 14, respectively. Is effectively realized by using the reinforcing members 11, 12, 13, and 14. It is possible.

  Moreover, with respect to the crossing part of the main-body part 1 and the protrusion parts 2 and 3, from the bending part 16e of the steel plate 16 which covers the main-body part 1 to the bending parts 16c and 16d of the steel plate 16 which covers the protrusion parts 2 and 3 Since the curved portion is continued through the intermediate bent portions 61 and 62 with the deformed portions 61a and 62a such as squeezing and thinning, the bent portion of the steel plate 16 is bent around the main body portion 1 and the protruding portions 2 and 3. While appropriately forming the portions 16e, 16c and 16d, the intermediate bent portions 61 and 62 obtained by deforming the intersecting corner portions 1x and 1y are smoothly connected to effectively correspond to specific irregular shapes. Can do.

Furthermore, since the left and right steel plates 16 and 16 are configured so as to be mirror-symmetrical as a whole, the furniture panel body is arranged facing to form furniture such as a desk shown in FIG. When the furniture such as the face-to-face desk shown in FIG. 11 is configured to be arranged together, the furniture panel body can be used for both left and right and front and rear in common.
And since the core material 15 is composed of a lightweight core material such as a paper honeycomb, it is possible to achieve both weight reduction and strength improvement, and there is no cheap sound when an object collides. Then, since human feet, chairs, wagons, etc. easily collide with the legs, it is possible to effectively improve the quality of the desk.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the furniture panel body has a U-shape. However, as shown in FIG. 13, as shown in FIG. As shown in FIG. 14, only an upper protruding portion 202 is provided in both directions from the main body portion 201 and can be used as an intermediate leg of a facing desk. A character-shaped furniture panel can also be constructed.

  Alternatively, in order to make this intermediate leg usable on a desk that is not facing, the L-shaped furniture panel body may be abutted back to back, and such an L-shaped furniture panel body (not shown) Of course, it is also possible to constitute.

  A reinforcing member is provided at a position surrounding the four sides of the core member, and a pair of opposing reinforcing members projecting in the same direction from the main body including the core member is a leg structure of a U-shaped leg or an H-shaped leg. If it is used, it becomes possible to finish the top plate holder (stay part) and leg part (base part) thinly while having high strength, and the same effect can be obtained for T-shaped legs and L-shaped legs. Can do.

  Moreover, the steel plate which pinches | interposes both sides of a core material with a reinforcing member is not restricted to a pair like the said embodiment, The whole may be connected to one.

  Moreover, the aspect which further expands a panel surface using the protrusion part from the main-body part of a reinforcing material is also possible. For example, the furniture panel body B shown in FIG. 15A has another reinforcing member 313x further opposed to the reinforcing member 313 with respect to the reinforcing member 313 of the protruding portion 302 protruding from the main body portion 301. The core member 315x is also disposed between the pair of reinforcing members 313, 313x, and these are sandwiched by metal plates (not shown) such as a steel plate from both sides in the same manner as in the above embodiment. The other reinforcing member 313x may or may not be joined to the front reinforcing member 311 constituting the main body 301. The core 315x may be integrated with or separate from the core 315 of the main body 301. It doesn't matter. This is because they are integrated after pressure bonding. FIG. 6B shows a modification in which the front reinforcing member 311 constituting the main body 301 is extended to a position that partitions the core members 315 and 315x. In these drawings, explanations and illustrations regarding other reinforcing members are partially omitted.

  Even if it is such a furniture panel body, various effects can be obtained similarly to the above embodiment. The illustrated one can be effectively used as an L-shaped top plate.

  Furthermore, in order to develop the shape from such an L-shaped top plate, as shown in FIG. 15C, a lightweight core material for forming a deformed portion 301z such as a curve on the outside of another reinforcing member 313x. A structure in which a shape filling material Z made of a wood material such as MDF or the like is disposed, and sandwiched by metal plates (not shown) from both sides while including the shape filling material Z is effective. If it does in this way, a rounded part etc. can be easily formed in the corner part of the main-body part 301 and the protrusion part 302. FIG. These shape filling materials Z may or may not be bonded to the reinforcing members 313x and 311. This is because they are integrated after pressure bonding.

  Furthermore, if the above-mentioned shape filling material is not a part that receives an overload like a top plate, the above-mentioned shape filling material can be retrofitted to a furniture panel body sandwiched with steel plates. is there.
