Description

[Technical Field]

[0001] The present invention relates to furniture with legs, such as benches and tables, for use indoors and outdoors. [Background technology]

[0002] Known legged furniture such as benches for indoor and outdoor use have a structure in which support legs are attached to both sides of the seat (see, for example, Patent Documents 1 and 2). As in Patent Documents 1 and 2, this type of bench is known to have rod-shaped reinforcing members attached between the seat and the support legs to prevent deformation or damage to the seat due to excessive load.

[0003] However, the conventional benches described in Patent Documents 1 and 2 above were designed so that the seat plate was not supported directly by the support legs but via an intermediate member, and furthermore, the reinforcing member was sandwiched and fixed between a recess formed in the lower part of the intermediate member and a recess formed in the upper part of the support legs.As a result, the presence of the intermediate member made it easy for a large gap to occur between the seat plate and the reinforcing member.

[0004] Therefore, unless the bench seat bends downward significantly, the seat and the reinforcing member will not come into contact, making it difficult to fully suppress deformation of the seat. Furthermore, the structure using the intermediate member not only increases the number of parts and increases costs, but also requires time and effort to connect the seat and the intermediate member, and the intermediate member and the support leg. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2016-67450 A [Patent Document 2] Japanese Patent Publication No. 2022-146001 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0006] The present invention aims to solve the problems of the prior art described above, and in summary, to provide furniture with legs such as a bench or table that is excellent in preventing bending deformation and breakage of the seat plate, and that is simple in structure and easy to assemble. [Means for solving the problem]

[0007] As a means for solving the above problem, the inventor constructed a piece of legged furniture F including a tabletop 1, support legs 2 attached to both the left and right sides of the tabletop 1, and a rod-shaped reinforcing member 3 attached below the tabletop 1 across the support legs 2 on both sides, while the support legs 2 have a ground contact portion 21 and an upper edge portion 22 having a support surface for the tabletop 1, and the upper edge portion 22 has a recess 22a formed on its inner surface, and an end of the reinforcing member 3 is inserted into the recess 22a (the effect will be described later).

[0008] In the present invention, the position and number of the reinforcing member 3 can be adjusted by forming a groove extending in the depth direction, which can be used as the recess 22a, or multiple recesses 22a arranged in the depth direction, on the inner surface of the upper edge portion 22 of the support leg 2.

[0009] In the present invention, by forming multiple recesses 22a within the partition groove portion using multiple ribs 22e formed at predetermined intervals in the depth direction within the groove portion of the upper edge portion 22 of the support leg 2, it is possible to easily form recesses 22a with an angular cross section and reinforce the upper edge portion 22.

[0010] In the present invention, the upper edge portion 22 of the support leg 2 is composed of an upper plate portion 22b and a lower plate portion 22c arranged parallel to the depth direction, and a side plate portion 22d forming the outer surface, and by fastening the top plate 1 to the upper plate portion 22b and fastening the reinforcing member 3 to the lower plate portion 22c, the end portion of the reinforcing member 3 can be hidden so that it cannot be seen from the outside, and the top plate 1 and reinforcing member 3 can be firmly fixed to the support leg 2 with screws or the like.

[0011] In the present invention, by forming a gripping portion 22f on the upper side of the support leg 22, into which both ends of the tabletop 1 are inserted, on the upper side of the support surface, it is possible to prevent the tabletop 1 from shifting in position in the vertical or depth direction, and it also becomes easier to temporarily fasten it during assembly.

[0012] In the present invention, the tabletop 1 is constructed by arranging a plurality of plate materials 11 in the depth direction, and the reinforcing member 3 and the recess 22a of the support leg 2 into which the end of this reinforcing member 3 is inserted are arranged between the plate materials 11, so that both plate materials 11 arranged on the upper side can be supported by a single reinforcing member 3 on the lower side.

[0013] In the present invention, a connecting plate 12 that connects multiple plate materials 11 together is attached in the depth direction to the middle portion of the width direction of the tabletop 1, and this connecting plate 12 is formed with a ring-shaped portion 12a or a clamp portion through which the reinforcing member 3 is inserted, thereby preventing bending deformation of the reinforcing member 3 and making positioning easier. [Effects of the Invention]

[0014] In this invention, the tabletop (including the seat) of legged furniture such as a bench or table is directly fixed to the support legs, and a recess is formed inside the upper edge of the support leg on which the tabletop is placed, and the end of the reinforcing member is inserted and fixed into this recess, so no intermediate member is required and the gap between the seattop and the reinforcing member can be minimized.As a result, when the tabletop bends downward, it immediately comes into contact with the reinforcing member and can distribute the load, thereby improving the effectiveness of preventing bending deformation and breakage of the tabletop.

[0015] Furthermore, because the legged furniture of the present invention does not require intermediate members, it not only reduces the number of parts and cuts costs, but also makes it easy to attach tabletops and reinforcing members to the support legs, speeding up the assembly of benches, tables, etc. In particular, the recesses on the upper edges of the support legs can be used to temporarily fasten the reinforcing members, preventing them from shifting position or falling off during assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0017] "First embodiment" A first embodiment of the present invention will be described with reference to Figs. 1 to 5. In the drawings, the symbol F indicates furniture with legs, and the symbol B indicates a bench. The symbol 1 indicates a tabletop, the symbol 2 indicates support legs, and the symbol 3 indicates a reinforcing member.

[0018] "Configuration of furniture with legs (bench)" [1] Basic configuration The basic configuration of the legged furniture F of this embodiment will be described. In this embodiment, as shown in Figures 1 to 3, the legged furniture F is constructed by attaching support legs 2 to both the left and right sides of the tabletop 1, and by attaching reinforcing members 3 across the support legs 2 below the tabletop 1 as shown in Figures 2(a) and (c). In this embodiment, the tabletop 1 is used as a seat, and the legged furniture F can be used as a bench B.

[0019] In this specification, the terms "width direction (left and right direction)," "height direction," and "depth direction" refer to the directions in the state in which the legged furniture F shown in Figures 1 and 2 is in use, and do not refer to the directions of each individual component shown in the figures.

[0020] As shown in FIG. 1, the support leg 2 has a ground contact portion 21 that comes into contact with the ground or floor surface, and an upper edge portion 22 that has a support surface for the top plate 1. Furthermore, the upper edge portion 22 of the support leg 2 has a recess 22a formed on the inner surface (inner surface in the left-right width direction) as shown in FIGS. 3(a) and (b), and an end of the reinforcing member 3 is inserted into this recess 22a as shown in FIG. 4.

[0021] With the above configuration, the distance between the table top 1 (seat) of the legged furniture F (bench B) and the reinforcing member 3 can be kept small, which not only improves the structural strength of the legged furniture F, but also enables the reinforcing member 3 to prevent the table top 1 from being deformed by a downward load. Furthermore, when assembling the legged furniture F, the reinforcing member 3 can be attached to the recess 22a of the support leg 2 for temporary fastening, which makes the assembly process easier.

[0022] [2] About the top plate [2-1] Top panel configuration Next, we will explain the components of the legged furniture F. In this embodiment, the table top 1 is configured by arranging a plurality of plate materials 11 in the depth direction with their lengths aligned as shown in Figures 1 and 2(b), and by connecting plates 12 that are hung across the back sides of the plate materials 11 as shown in Figure 2(c), connecting the plurality of plate materials 11 together.

[0023] In this embodiment, the table top 1 is made up of four plates 11 to form the seat of the bench B, but the dimensions, number, and shape of the plates 11 can be changed as appropriate depending on the shape of the seat of the bench B. When the legged furniture F is used as a table or the like, the number of plates 11 can be increased or decreased depending on the required dimensions, shape, etc. of the table top 1. The table top 1 can be any plate that can form a seat or table surface, and a single plate can also be used.

[0024] [2-2] Materials for the tabletop In this embodiment, the material for the tabletop 1 is a hollow wood powder-containing plastic plate as the plate material 11, but the materials for the tabletop 1 and the plate material 11 are not particularly limited, and it is also possible to use solid plastic plates without wood powder, wood (solid wood, laminated wood, plywood, etc.), metal plates, stone plates, etc., and it is also possible to form the tabletop 1 by combining plate materials 11 made of different materials.

[0025] [2-3]Connection plate In this embodiment, a strip-shaped metal plate is used as the connecting plate 12 connecting the plurality of plate materials 11 together, but the shape and material are not particularly limited. In this embodiment, the connecting plate 12 is attached in the depth direction to the middle portion in the width direction of the tabletop 1 as shown in Fig. 2(c), but multiple connecting plates 12 can also be attached at different positions in the width direction to match the left and right width of the tabletop 1. In this embodiment, the connecting member 12 is fastened to the plate material 11 by a screw member N as shown in Fig. 4, but the attachment method is not particularly limited.

[0026] 2(c) and 5, a ring-shaped portion 12a is formed on one side of the connecting plate 12, and the reinforcing member 3 is inserted into this ring-shaped portion 12a. This not only prevents the reinforcing member 3 from being flexed, but also makes it easier to position the reinforcing member 3 when temporarily fastening it to the top plate 1. The shape of the ring-shaped portion 12a of the connecting plate 12 may be circular or semicircular, other than rectangular, as long as it corresponds to the cross-sectional shape of the reinforcing member 3.

[0027] In this embodiment, the annular portion 12a of the connecting plate 12 is formed by processing it into a linear shape that is narrower than the strip-shaped main body portion as shown in Fig. 5, but the annular portion 12a can also be formed by joining two metal plates with a bent portion on one side, or by attaching a U-shaped member to a metal plate. The annular portion 12a can also be C-shaped with a broken portion as long as the reinforcing member 3 does not fall off, and a clamp portion that holds the reinforcing member 3 inserted can also be provided instead.

[0028] 5, the connecting plate 12 has a length spanning four plate members 11 and has two annular portions 12a, but the length of the connecting plate 12 and the number of annular portions 12a can be changed as appropriate. Also, when using a tabletop 1 with a large depth, multiple connecting plates 12 can be attached in a linear arrangement in the depth direction.

[0029] [3] Support legs [3-1] Shape of support legs 3(a) and 3(b), in this embodiment, the support leg 2 has a square-shaped annular shape including a plate-shaped grounding portion 21 that contacts the ground or floor surface, a plate-shaped upper edge portion 22 that makes surface contact with the top plate 1 placed on it, and support portions 23 that connect the grounding portion 21 and the upper edge portion 22 at the front and rear. The shape of the support leg 2 is not limited to this embodiment and can be changed as appropriate as long as it has the upper edge portion 22.

[0030] For example, the ground contact portion 21 does not necessarily have to be a plate (or rod) shape connecting the support portions 23, but a base portion can be provided at the bottom of each of the front and rear support portions 23, and these can serve as the ground contact portion 21. The support portions 23 of the support leg 2 do not necessarily have to be provided at the front and rear, but a form in which they are provided only at the front or rear, or a form in which the support portion 23 is provided in the center of the front and rear, can also be adopted. The support portions 23 of the support leg can also be used as a surface material to connect the ground contact portion 21 and the upper side portion 22 via the surface material.

[0031] [3-2] Shape of the top edge In this embodiment, the shape of the upper side portion 22 of the support leg 2 is a U-shaped cross section having an upper plate portion 22b and a lower plate portion 22c arranged parallel to the depth direction, and a side plate portion 22d forming an outer surface, and a groove portion extending in the depth direction that can be used as a recess 22a is formed on the inner surface (inner surface in the width direction) of the upper side portion 22 of the support leg 2. Furthermore, in this embodiment, a plurality of ribs 22e (partitions) are formed in the groove portion of the upper side portion 22 of the support leg 2 at predetermined intervals in the depth direction, and the groove portion is partitioned to form a plurality of recesses 22a in the groove portion.

[0032] By adopting the above configuration, it is possible to form a plurality of recesses 22a in the groove at predetermined intervals, thereby adjusting the position and number of reinforcing members 3. Furthermore, by forming ribs 22e in the groove of upper side portion 22, not only can recesses 22a with a square cross section be easily formed, but the inside of the groove of upper side portion 22 can be reinforced by ribs 22e, making it less likely that upper side portion 22 will be deformed or damaged by a load.

[0033] [3-3] Number, shape, and arrangement of recesses In this embodiment, the cross-sectional shape of the recess 22a formed in the upper edge portion 22 of the support leg 2 is rectangular, the same as the cross-sectional shape of the reinforcing member 3, as shown in Fig. 3, but it can also be circular if a single pipe or the like is used for the reinforcing member 3. In addition, in this embodiment, two recesses 22a are formed at a predetermined interval as shown in Fig. 3, but one or three or more recesses can be formed as needed. In addition, the groove formed in the upper edge portion 22 can be used as the recess 22a without being partitioned by the rib 22e, in which case the position of the reinforcing member 3 can be freely adjusted.

[0034] In this embodiment, as shown in Figures 2(c) and 4, recesses 22a of the support legs 2 into which the ends of the reinforcing members 3 are inserted are disposed between adjacent plate materials 11 that constitute the top board 1. This allows the reinforcing members 3 to be disposed between the plate materials 11, so that both plate materials 11 disposed on the upper side can be supported by a single reinforcing member 3 on the lower side. The depth of the recesses 22a can also be adjusted as appropriate within a range that prevents the ends of the reinforcing members 3 from falling off, and they can also be made into through holes.

[0035] [3-4] Fixing means for the top plate and reinforcing member 3(a)(b) and 4, a screw insertion hole H1 is provided in a predetermined portion of the upper plate portion 22b of the upper side portion 22 (a portion where the recess 22a into which the reinforcing member 3 is inserted is not formed), and a screw insertion hole H2 is provided in each of the recesses 22a of the lower plate portion 22c. This allows the plate material 11 of the tabletop 1 to be fastened to the upper plate portion 22b with the screw member N, and the reinforcing member 3 to be fastened to the lower plate portion 22c with the screw member N, so that the tabletop 1 and the reinforcing member 3 can be securely fixed to the support leg 2 with screws or the like. Note that means for fastening the tabletop or the reinforcing member 3 to the support leg 2 can also be achieved by means other than screws, such as fitting, locking, or adhesive, and the screw insertion holes H1 and H2 in the upper plate portion and the lower plate portion can also be drilled on-site without being pre-formed.

[0036] With the above configuration, the table top 1 and the reinforcing member 3 can be fixed via the upper plate portion 22b, so the gap between them can be kept very small, equal to the thickness of the upper plate portion 22b. Furthermore, by minimizing the gap between the table top 1 and the reinforcing member 3, it becomes possible for the reinforcing member 3 to prevent the table top 1 from being flexed or deformed even when a downward load is applied to the table top 1.

[0037] [3-5] Grip In this embodiment, as shown in Figures 2(b) and 3(a) and (b), gripping portions 22f into which both ends of the tabletop 1 are inserted are formed on the upper side of the top edge portion 22 of the support leg 2 above the mounting surface of the tabletop 1. This prevents misalignment of the tabletop 1 in the vertical or depth direction and also makes it easier to temporarily fasten the tabletop 1 (plate material 11) during assembly. In this embodiment, gripping portions 22f of the top edge portion 22 are formed in a shape that covers the side, top, and end faces of the tabletop 1, but they can also be shaped to cover the end faces and top surface or the end faces and side faces of the tabletop 1.

[0038] [3-6] Example of changing the shape of the top edge In this embodiment, as shown in FIG. 1, a side plate portion 22d is provided on the upper edge portion 22 of the support leg 2 so that the end portion of the reinforcing member 3 cannot be seen from the outside. However, it is also possible to adopt a shape that does not have the side plate portion 22d by providing a stopper such as a protrusion inside the recess 22a, in which case the recess 22a becomes a through hole.

[0039] [3-7] Materials for the support legs Metallic materials such as stainless steel, iron, aluminum, and other metallic materials can be suitably used for the material of the support leg 2. When used outdoors, it is preferable to use a material with excellent weather resistance, and materials other than metallic materials such as plastic materials, wood, and composite materials can also be used for the support leg 2.

[0040] [3-8] Support leg height In this embodiment, the legged furniture F is configured so that it can be used as a bench B by making the height of the support legs 2 lower than waist level, but it can also be used as a table by making the height of the support legs 2 higher.

[0041] [4] Reinforcement materials In this embodiment, a metal square pipe is used for the reinforcing member 3, but hollow or solid rods made of plastic or wood other than metal can also be used as long as they have the required strength. Regarding the reinforcing member 3, it is preferable to use a square pipe or square timber with a square cross section so that the tabletop 1 can be supported on a surface, but single pipes or round bars with a circular cross section can also be used. Regarding the number of reinforcing members 3, two are used in this embodiment, but this can be adjusted as appropriate depending on the area of ​​the tabletop 1 and the required strength.

[0042] In this embodiment, as shown in Fig. 4, a groove 31 extending in the longitudinal direction is formed in the center of the top surface of the reinforcing member 3, so that the positioning work can be easily performed by inserting the tip of the screw member N into this groove 31. In this embodiment, one groove 31 is formed in the portion where the screw member N is fastened, but if multiple screw members N are fastened, multiple grooves 31 can also be formed in corresponding positions.

[0043] [5] Other examples of changes In this embodiment, the furniture with legs F is configured as a bench B without a backrest, but it can also be configured as a bench with a backrest by forming a backrest portion on the rear side. Furthermore, the uses of the furniture with legs F are not limited to benches and tables, but can also be used for various stands, cabinets, etc. [Explanation of symbols]
