Description
本発明は、屋内外で使用されるベンチの座面用部品、およびそれを用いたベンチに関するものである。 The present invention relates to seat components for benches used indoors and outdoors, and benches using such components.
屋内外で使用される脚付きのベンチに関しては、複数の桟材(横材)から構成される座面部の両側に脚部材が取り付けられたものが広く知られている(例えば、特許文献１参照)。またこの種のベンチにおいては、座面部の左右両側と脚部材とをＬ型金具(特許文献１の図７参照)を介して連結する構造が一般的である。 A widely known type of bench with legs for use indoors and outdoors is one in which leg members are attached to both sides of a seat made up of multiple crosspieces (see, for example, Patent Document 1). Furthermore, this type of bench typically has a structure in which the left and right sides of the seat and the leg members are connected via L-shaped metal fittings (see Figure 7 of Patent Document 1).
しかしながら、上記Ｌ型金具を用いる従来のベンチにおいては、座面部を構成する複数の桟材を連結する部材が必要であり(特許文献１の図４参照)、複雑な形状のＬ型金具を使用する必要があったため、ベンチのコストが高く付き易かった。またＬ型金具を使用する従来のベンチは、脚部材の左右位置の調節も難しいという欠点があった。 However, conventional benches using the above-mentioned L-shaped metal fittings require connecting members for connecting the multiple crosspieces that make up the seat (see Figure 4 of Patent Document 1), and because they require the use of L-shaped metal fittings with complex shapes, the cost of the bench tends to be high. Furthermore, conventional benches using L-shaped metal fittings have the disadvantage that it is difficult to adjust the left-right position of the leg members.
一方、上記ベンチの座面部の底面側に平板状の連結金具を取着して桟材を連結し、更にその連結金具に脚部材を取り付ける場合、ベンチを上側から見たとき桟材の間から連結金具が露出してしまうため、脚部材の取り付け位置を調節できるように連結金具の面積を大きくするとベンチの外観が損なわれてしまう問題があった。 However, if flat connecting fittings are attached to the underside of the seat of the bench to connect the crosspieces, and then the leg members are attached to the connecting fittings, the connecting fittings will be exposed between the crosspieces when the bench is viewed from above. Therefore, if the area of the connecting fittings is increased to allow the leg member attachment position to be adjusted, the appearance of the bench will be marred.
本発明は、上記従来技術の問題を解決することを課題としており、要約すると座面部の左右方向における脚部材の取り付け位置を調節することができ、上側から見たときの外観にも優れ、製造コストも低廉に抑えられるベンチの座面用部品、およびそれを用いたベンチを提供することにある。 The present invention aims to solve the problems of the prior art described above. In summary, it aims to provide a bench seat component that allows the attachment position of the leg members in the left-right direction of the seat to be adjusted, has an excellent appearance when viewed from above, and can be manufactured at low cost, as well as a bench using the same.
本発明者は、上記課題を解決する手段として、複数の桟材11を奥行方向に並べて構成された座面部１と、脚部材２を受けるための金具であって、前記座面部１の左右両側の下面に桟材11をかけ渡した状態で取着される平板状の第一金具３と、を含んでベンチＢの座面用部品を構成し、前記第一金具３の左右一方に、桟材11の各隙間の位置に対応する切欠き部31を櫛歯状に形成した。 As a means to solve the above problem, the inventor constructed a seat component for bench B, which includes a seat portion 1 constructed by arranging multiple crosspieces 11 in the depth direction, and a flat first metal fitting 3 that is a metal fitting for receiving leg members 2 and is attached to the underside of the left and right sides of the seat portion 1 with the crosspieces 11 draped across it. In addition, comb-shaped notches 31 were formed on either the left or right side of the first metal fitting 3, corresponding to the positions of each gap in the crosspieces 11.
また上記座面用部品に脚部材２を取り付け、前記座面部１の左右両側の下面に、前記脚部材２よりも左右幅が大きい平板状の第一金具３を複数の桟材11をかけ渡した状態で取着すると共に、前記脚部材２の上面に、脚部材２よりも左右幅が大きい平板状の第二金具４を脚部材２の左右一方に突き出した状態で取着して、当該第二金具４の突出部位41で前記第一金具３と第二金具４を止着してベンチＢを構成した。これにより第二金具４によって脚部材２の取り付け位置を容易に変更できる。またベンチＢの座面部への荷重で桟材11が撓んだ場合でも、平板状の第二金具４の弾性変形でネジ留め部への負荷を吸収できる。 The leg members 2 are attached to the seat components, and flat first metal fittings 3, each wider than the leg members 2, are attached to the underside of both the left and right sides of the seat portion 1 with multiple crosspieces 11 spanning them. Also, flat second metal fittings 4, each wider than the leg members 2, are attached to the top of the leg members 2 so that they protrude from either the left or right side of the leg members 2. The first metal fittings 3 and second metal fittings 4 are fastened together at the protruding portions 41 of the second metal fittings 4 to form bench B. This allows the attachment position of the leg members 2 to be easily changed using the second metal fittings 4. Even if the crosspieces 11 bend due to the load on the seat portion of bench B, the elastic deformation of the flat second metal fittings 4 can absorb the load on the screw fastening portions.
また上記第二金具４を一列に並んだ複数の脚部材２をかけ渡して取着することにより第二金具４を脚部材２の連結材としても利用できる。 Furthermore, by attaching the second metal fitting 4 across a row of leg members 2, the second metal fitting 4 can also be used as a connecting member for the leg members 2.
また上記脚部材２を、上下方向の中空部を有する脚本体部21と、当該脚本体部21の中空部内に挿入された芯材22とから構成し、前記芯材22の上端部に前記第二金具４を取着することもできる。これにより脚本体部21がプラスチック製であったとしても、第二金具４が芯材22に取着されているため、第二金具４から脚本体部21に荷重がかかり難い。 The leg member 2 can also be constructed from a leg body 21 with a vertically hollow portion and a core material 22 inserted into the hollow portion of the leg body 21, with the second metal fitting 4 attached to the upper end of the core material 22. In this way, even if the leg body 21 is made of plastic, the second metal fitting 4 is attached to the core material 22, making it less likely that a load will be applied from the second metal fitting 4 to the leg body 21.
また上記脚部材２の芯材22の上下長さを脚本体部21よりも大きくすることにより、第二金具４からの荷重が芯材22にかかるため、脚本体部21の変形や破損を防止できる。 Furthermore, by making the vertical length of the core material 22 of the leg member 2 greater than that of the leg body 21, the load from the second metal fitting 4 is applied to the core material 22, preventing deformation or damage to the leg body 21.
また本発明では、上記座面部１の左右両側の下面に、前記脚部材２よりも左右幅が大きい平板状の第一金具３を複数の桟材11をかけ渡した状態で取着すると共に、前記第一金具３の非櫛歯部33の両端に、座面と平行に形成された底辺部24、底辺部24の両側が上方に立ち上がった立上り部25、並びに立上り部25の上端が内側に折れ曲がった折返し部26を有する上側が開口したＣ型形状の脚部材２を止着してベンチＢを構成することができる。これにより第一金具３で桟材11の連結を行えるため、環状の脚部材２を使用する必要がなく、脚部材をＣ型形状とすることでベンチを軽量化できる。 In addition, in this invention, bench B can be constructed by attaching flat first fittings 3, which are wider than the leg members 2, to the underside of both the left and right sides of the seat portion 1, with multiple crosspieces 11 spanning them, and fastening C-shaped leg members 2, which are open at the top, to both ends of the non-tooth portion 33 of the first fittings 3. The leg members 2 have a base portion 24 formed parallel to the seat surface, rising portions 25 rising upward on both sides of the base portion 24, and a folded portion 26 where the upper end of the rising portion 25 is bent inward. This allows the crosspieces 11 to be connected using the first fittings 3, eliminating the need for ring-shaped leg members 2, and using C-shaped leg members allows for a lighter bench.
本発明のベンチの座面用部品は、平板状の第一金具によって座面部を構成する複数の桟材を連結一体化することができるだけでなく、この第一金具に対して脚部材の連結も行うことができるため、第一金具の範囲内で座面の左右方向における脚部材の取り付け位置を容易に調節することができる。 The bench seat component of the present invention not only uses a flat first metal fitting to connect and integrate the multiple crosspieces that make up the seat portion, but also allows the leg members to be connected to this first metal fitting, making it easy to adjust the attachment position of the leg members in the left-right direction of the seat within the range of the first metal fitting.
しかも、本発明においては、上記第一金具の左右一方に複数の切欠き部を設けて櫛歯状に形成しているため、第一金具の非櫛歯部の下方に脚部材を取り付けた際に、桟材の隙間から第一金具が露出する問題も解消できるため、ベンチを上側から見たときの外観も損なわれない。 Furthermore, in this invention, multiple notches are provided on either the left or right side of the first metal fitting, forming it in a comb-tooth shape. This eliminates the problem of the first metal fitting being exposed through gaps in the crosspiece when a leg member is attached below the non-comb-tooth portion of the first metal fitting, and therefore does not impair the appearance of the bench when viewed from above.

［１］基本構成について
本実施形態のベンチＢの基本構成について説明する。本実施形態では、図１及び図２(a)～(c)に示すように、複数の桟材11を奥行方向に並べて構成された座面部１と、この座面部１の両側に取り付けられた一対の脚部材２とからベンチＢを構成している。また座面部１の裏面には、図３(a)に示すように、脚部材２を受けるための平板状の第一金具３を座面部１の左右両側の下面に桟材11をかけ渡した状態で取着して座面用部品を構成している。第一金具３については、図３(a)(b)に示すように第一金具３の左右一方に、桟材11の各隙間の位置に対応する切欠き部31を櫛歯状に形成している。
"Bench configuration"
[1] Basic Configuration The basic configuration of the bench B of this embodiment will be described. In this embodiment, as shown in Figures 1 and 2(a) to 2(c), the bench B is composed of a seat portion 1 formed by arranging multiple crosspieces 11 in the depth direction, and a pair of leg members 2 attached to both sides of the seat portion 1. Furthermore, as shown in Figure 3(a), flat first metal fittings 3 for receiving the leg members 2 are attached to the underside of the seat portion 1 on both the left and right sides, with the crosspieces 11 spanning across the underside, thereby forming a seat component. As shown in Figures 3(a) and 3(b), the first metal fitting 3 has comb-like notches 31 formed on either the left or right side thereof, corresponding to the positions of the gaps in the crosspieces 11.
上記座面部１の左右両側の下面には、図２(c)及び図４(a)に示すように脚部材２よりも左右幅が大きい第一金具３を取着すると共に、脚部材２の上面に、脚部材２よりも左右幅が大きい平板状の第二金具４を脚部材２の左右一方に突き出した状態で取着している。そして、この第二金具４の突出部位41で第一金具３と第二金具４を止着することにより脚部材２の取り付けを行っている。なお本明細書中においては、図２(b)をベンチＢの正面視とし、この正面視における方向を基準として図２(a)(b)に示すようにベンチＢ及びその部品の左右方向、奥行方向、高さ方向を特定する。 As shown in Figures 2(c) and 4(a), first metal fittings 3, which are wider than the leg members 2, are attached to the underside of both the left and right sides of the seat portion 1, and flat second metal fittings 4, which are wider than the leg members 2, are attached to the top surfaces of the leg members 2, protruding to one side of the leg members 2. The leg members 2 are attached by fastening the first metal fittings 3 and the second metal fittings 4 together at the protruding portions 41 of the second metal fittings 4. Note that throughout this specification, Figure 2(b) is a front view of bench B, and the left-right, depth, and height directions of bench B and its components are specified as shown in Figures 2(a) and 2(b) based on the directions in this front view.
［２］座面用部品について
［2-1］座面部の桟材の材料
次に上記ベンチＢの各構成要素について説明する。まず上記座面部１の桟材11の材質に関しては、本実施形態ではプラスチック製の板材を使用しているが、屋外また屋内のベンチの座面に使用される一般的な材料であれば、種々のプラスチック材料(例えば、ポリプロピレンやＡＢＳ樹脂、塩化ビニル樹脂等を単体または組み合わせたもの)、木材または金属材料(例えば、アルミニウムやステンレス等)、複合材料などを使用できる。
[2] Seat Components [2-1] Material of the Crosspiece of the Seat Section Next, we will explain each component of the bench B. First, regarding the material of the crosspiece 11 of the seat section 1, in this embodiment, a plastic plate material is used, but any common material used for the seat of an indoor or outdoor bench can be used, such as various plastic materials (for example, polypropylene, ABS resin, polyvinyl chloride resin, etc., either alone or in combination), wood or metal materials (for example, aluminum, stainless steel, etc.), composite materials, etc.
［2-2］座面部の桟材の形状・配置
上記桟材11の形状は、本実施形態では長さ方向の中空部を有する４本の中空板を使用しているが、中実板や角棒、丸棒、角パイプ、丸パイプ等を使用することもできる。上記桟材11の寸法(幅・長さ・厚さ)に関しても適宜変更することができ、座面部１を形成する桟材11の数に関しても、２本以上であればベンチＢの奥行きや各桟材11の寸法に応じて適宜変更できる。本実施形態では、同じ寸法の桟材11から座面部１を形成しているが、異なる寸法・材質の桟材11から座面部１を構成することもできる。上記桟材11の間隔に関しても、桟材11の種類に応じて任意に調整できる。また本実施形態では、中空板から成る各桟材11の底面に水抜き孔12を形成すると共に、各桟材11の両端にキャップ部材11aを装着して中空部を塞いでいる。
[2-2] Shape and Arrangement of the Crosspieces of the Seat Section: In this embodiment, the crosspieces 11 are four hollow plates with longitudinal hollows. However, solid plates, square bars, round bars, square pipes, round pipes, etc. can also be used. The dimensions (width, length, and thickness) of the crosspieces 11 can be varied as needed, and the number of crosspieces 11 forming the seat section 1 can be varied as needed depending on the depth of the bench B and the dimensions of each crosspiece 11, as long as there are two or more crosspieces. In this embodiment, the seat section 1 is formed from crosspieces 11 of the same dimensions. However, the seat section 1 can also be formed from crosspieces 11 of different dimensions and materials. The spacing between the crosspieces 11 can also be adjusted as needed depending on the type of crosspiece 11. In this embodiment, drainage holes 12 are formed in the bottom surface of each hollow plate crosspiece 11, and cap members 11a are attached to both ends of each crosspiece 11 to seal the hollows.
［2-3］第一金具
上記座面部１に取り付ける第一金具３に関しては、図３(a)(b)に示すように矩形状の平板の一方の長辺部に短辺方向の切欠き部31を長辺方向に複数(本実施形態では３つ)形成して櫛歯部32を設けている。切欠き部31の間隔(溝幅)や数は座面部１を形成する桟材11の間隔や数に合わせ、切欠き部31の長さは平板の短辺の半分程度の大きさとしている。なお平板の長辺の長さは、座面部の奥行と同じまたはそれよりも若干小さい程度に形成するのが好ましく、切欠き部31の間隔(溝幅)は、桟材11の間隔と同じまたはそれよりも若干大きい程度に形成するのが好ましい。平板の短辺の長さは、脚部材２の左右方向の取り付け位置を調整する範囲に応じて適宜変更でき、長辺と同じ長さあるいは長辺以上の長さに設計することもできる。
[2-3] First Metal Fitting The first metal fitting 3 attached to the seat 1 has, as shown in Figures 3(a) and 3(b), a rectangular flat plate with multiple (three in this embodiment) notches 31 formed in the short-side direction along one long side of the plate, forming comb-tooth portions 32. The spacing (groove width) and number of the notches 31 correspond to the spacing and number of the crosspieces 11 forming the seat 1, and the length of the notches 31 is approximately half the length of the short side of the flat plate. The length of the long side of the flat plate is preferably the same as or slightly smaller than the depth of the seat, and the spacing (groove width) of the notches 31 is preferably the same as or slightly larger than the spacing between the crosspieces 11. The length of the short side of the flat plate can be adjusted appropriately depending on the range of adjustment required for the left-right mounting position of the leg member 2, and can also be designed to be the same length as or longer than the long side.
一方、上記切欠き部31が形成されていないもう一方の長辺側の非櫛歯部33には、第一金具３と座面部１を連結するためのネジ孔Ｈ1を平板の長辺方向に所定間隔で複数設けている。更に本実施形態では、第二金具４との連結に利用するネジ孔Ｈ2を、非櫛歯部33の櫛歯部32近傍および櫛歯部32の基端部に２つ並べて形成しているが、一方のみに形成することもできる。これらのネジ孔Ｈ1・Ｈ2の配置は各桟材11の位置に対応させており、更に第二金具４との連結に利用するネジ孔Ｈ2は第二金具４のネジ孔の位置に合わせて形成している。平板の厚みは所定の剛性を有する範囲内であれば適宜変更できる。 Meanwhile, in the non-tooth portion 33 on the other long side where the notch 31 is not formed, a plurality of screw holes H1 for connecting the first fitting 3 and the seat portion 1 are provided at predetermined intervals along the long side of the flat plate. Furthermore, in this embodiment, two screw holes H2 used for connecting the second fitting 4 are formed side by side, one near the tooth portion 32 of the non-tooth portion 33 and the other at the base end of the tooth portion 32, but they can also be formed on only one side. The arrangement of these screw holes H1 and H2 corresponds to the position of each crosspiece 11, and further, screw hole H2 used for connecting the second fitting 4 is formed to match the position of the screw hole in the second fitting 4. The thickness of the flat plate can be changed as long as it has a predetermined rigidity.
本実施形態では、第一金具３にステンレス平板を使用しているが、金具の材料に関してはスチールやアルミニウム、銅、亜鉛合金など、他の金属材料を使用することもできる。また第一金具３と座面部１の桟材11の取り付け構造に関しては、ボルト・ナットやビスを用いたネジ留め構造を採用することができ、桟材11の位置に合わせて形成したネジ孔Ｈ1・Ｈ2にネジ部材Ｎ1・Ｎ2を挿通して座面部１に固定する方法であれば適宜変更できる。また第一金具３の櫛歯形状に関しては、各桟材11の隙間の数や大きさに合わせて切欠き部31の数や形状を適宜変更できる。第一金具３の切欠き部31の形成方法に関しては、打ち抜き加工や切削加工、溶接加工などにより形成することができる。 In this embodiment, a stainless steel flat plate is used for the first fitting 3, but other metal materials such as steel, aluminum, copper, and zinc alloy can also be used for the fitting material. Furthermore, the attachment structure between the first fitting 3 and the crosspiece 11 of the bearing surface 1 can be a screw-fastening structure using bolts, nuts, or screws, and can be modified as needed as long as the method involves inserting screw members N1 and N2 into screw holes H1 and H2 formed to match the positions of the crosspiece 11 to fasten them to the bearing surface 1. Furthermore, with regard to the comb-tooth shape of the first fitting 3, the number and shape of the notches 31 can be modified as needed to match the number and size of the gaps in each crosspiece 11. The notches 31 of the first fitting 3 can be formed by punching, cutting, welding, or other processes.
［2-4］座面部の桟材の連結
上記座面部１を構成する桟材11の連結は、図３(a)(b)に示すように第一金具３によって行われるが、桟材11の長さが大きい(座面部１の左右幅が大きい)場合には、図３(a)(c)に示すように座面部１の左右中間位置にネジ孔Ｈ1を有する桟材連結用の第三金具５を使用することもできる。第三金具５に関しては、平板状の金具を好適に使用できるが、剛性に優れた金属製の角パイプやチャンネル材などを使用することもでき、また座面部１の左右中間位置をネジ止めによって連結することもできる。
[2-4] Connecting the crosspieces of the seat portion The crosspieces 11 that make up the seat portion 1 are connected by first fittings 3 as shown in Figures 3(a) and 3(b), but if the length of the crosspieces 11 is large (the left-to-right width of the seat portion 1 is large), it is also possible to use a third fitting 5 for connecting the crosspieces, which has a screw hole H1 at the left-to-right middle position of the seat portion 1 as shown in Figures 3(a) and 3(c). For the third fitting 5, a flat metal fitting can be suitably used, but metal square pipes or channel members with excellent rigidity can also be used, and the left-to-right middle position of the seat portion 1 can also be connected by screwing.
［2-5］桟材への芯材の挿入
本実施形態では、長さ方向の中空部を有する桟材11に対して棒状の芯材13を挿入して座面部１の剛性を高めている。本実施形態では、図４(b)に示すように桟材11に中間位置の仕切り部で区切られた複数の中空部を設けて、それらの中空部の一つ(本実施形態では奥行方向の内側の中空部)に芯材13を挿入して構成している。更に本実施形態では、図３(a)(b)に示す第一金具３のネジ孔Ｈ1・Ｈ2に図４(a)に示すネジ部材Ｎ1・Ｎ2をそれぞれ取り付けて、図４(b)に示すように芯材13が挿入されていない別の中空部(本実施形態では奥行方向の外側)に各ネジ部材の先端が貫通するようにしている。これによりボルトやビス等のネジ部材Ｎ1・Ｎ2が、桟材11の中空部に挿入した芯材13と干渉する問題を防止できる。芯材13に関しては、ステンレス材を使用しているが桟材11よりも剛性の高い材料であれば、金属材料や複合材料などを適宜選択して使用できる。
[2-5] Insertion of Core Material into Crosspiece 1 In this embodiment, a rod-shaped core material 13 is inserted into a crosspiece 11 having a longitudinal hollow portion to increase the rigidity of the bearing surface portion 1. In this embodiment, as shown in FIG. 4(b), the crosspiece 11 has multiple hollow portions separated by partitions at intermediate positions, and the core material 13 is inserted into one of these hollow portions (in this embodiment, the inner hollow portion in the depth direction). Furthermore, in this embodiment, the screw members N1 and N2 shown in FIG. 4(a) are attached to the screw holes H1 and H2 of the first fitting 3 shown in FIGS. 3(a) and 3(b), respectively, so that the tip of each screw member penetrates another hollow portion (in this embodiment, the outer hollow portion in the depth direction) where the core material 13 is not inserted, as shown in FIG. 4(b). This prevents interference between the screw members N1 and N2 , such as bolts or screws, and the core material 13 inserted into the hollow portion of the crosspiece 11. Although stainless steel is used for the core material 13, any suitable metal material or composite material may be used as long as it has higher rigidity than the crosspiece material 11.
上記第一金具３は、図３(a)に示すように切欠き部31が形成された櫛歯部が左右外側を向くように座面部１に対して取り付けられる。座面部１の左右幅が大きい場合には、第一金具３を座面部１の左右中間位置に取り付けることもでき、その場合にも櫛歯部が座面部１の左右外側を向くように取り付けるのが好ましい。また本実施形態では、第一金具３の櫛歯部の端部が座面部１の左右両端の位置にくるように取り付けている。これにより脚部材２を座面部１の左右両端の下方に取り付けることができる。 As shown in Figure 3(a), the first metal fitting 3 is attached to the seat 1 so that the comb-tooth portion where the cutouts 31 are formed faces outward on the left and right. If the seat 1 has a large width, the first metal fitting 3 can be attached to the middle position between the left and right of the seat 1, and in that case, it is preferable to attach it so that the comb-tooth portion faces outward on the left and right of the seat 1. In this embodiment, the first metal fitting 3 is attached so that the ends of the comb-tooth portion are located at both left and right ends of the seat 1. This allows the leg members 2 to be attached below both left and right ends of the seat 1.
［３］脚部材について
［3-1］脚部材の構造
次に上記脚部材２に関しては、本実施形態では図４(b)に示すように上下方向の中空部を有するプラスチック製の脚本体部21と、この脚本体部21の中空部内に挿入された芯材22とから構成している。そして芯材22の上端部に第二金具４を取着して、第二金具４からの荷重が脚本体部21ではなく芯材22にかかるようにしている。更に本実施形態では、芯材22の上下長さを脚本体部21よりも大きくして第二金具４からの荷重が芯材22にかかるようにしている。なお脚部材２の構造に関しては、脚本体部21に剛性および耐久性の高い材料を使用する場合には芯材22を用いない構造を採用することもできる。
[3] Regarding the leg member [3-1] Structure of the leg member Next, in this embodiment, the leg member 2 is composed of a plastic leg body 21 having a vertically hollow portion, and a core material 22 inserted into the hollow portion of the leg body 21, as shown in Figure 4(b). A second metal fitting 4 is attached to the upper end of the core material 22 so that the load from the second metal fitting 4 is applied to the core material 22 rather than the leg body 21. Furthermore, in this embodiment, the vertical length of the core material 22 is greater than that of the leg body 21 so that the load from the second metal fitting 4 is applied to the core material 22. Note that with regard to the structure of the leg member 2, a structure without a core material 22 can be adopted if a highly rigid and durable material is used for the leg body 21.
［3-2］脚部材の材料・形状
上記脚本体部21の材料については、、所定の剛性を有する材料であればよく、例えば、種々のプラスチック材料(例えば、ポリプロピレンやＡＢＳ樹脂、塩化ビニル樹脂等を単体または組み合わせたもの)や金属材料(例えば、ステンレスや鉄等)、複合材料(繊維強化プラスチック等)などを使用することができる。また脚本体部21の形状は、角柱型のものだけでなく円柱型、角錐型、円錐型、金属枠(詳しくは第二実施形態参照)などの形態を採用でき、芯材22を用いない場合には中実形状を採用することもできる。上記芯材22の材料には、ステンレス材を使用しているが脚本体部21よりも剛性の高い材料であれば、金属材料や複合材料などを適宜選択して使用できる。
[3-2] Material and Shape of Leg Members The material for the leg body 21 may be any material with a predetermined rigidity, such as various plastic materials (e.g., polypropylene, ABS resin, polyvinyl chloride resin, etc., either alone or in combination), metal materials (e.g., stainless steel, iron, etc.), or composite materials (fiber-reinforced plastic, etc.). The shape of the leg body 21 can be not only prismatic, but also cylindrical, pyramidal, conical, or metal frame (see the second embodiment for details). If the core member 22 is not used, a solid shape can also be used. While stainless steel is used for the core member 22, any suitable metal or composite material can be used as long as it is more rigid than the leg body 21.

上記脚部材２に取り付ける第二金具４に関しては、本実施形態では図２(c)および図４(a)(b)に示すように座面部１の奥行きに応じた長さのステンレス平板から形成している。第二金具４の材料に関しては、座面部１の変形に応じて弾性変形する材料であれば他の金属材料を使用することもできる。また第二金具４には、複数の脚部材２および第一金具３の取り付け位置に合わせてボルトやビス等のネジ部材Ｎ2の挿通孔を形成している。なお本実施形態では、第二金具４の上側からネジ部材を脚部材２の芯材22に挿通して第二金具の取り付けを行っている(図示せず)。
[3-3] Second Metal Fitting In this embodiment, the second metal fitting 4 attached to the leg member 2 is formed from a stainless steel flat plate with a length corresponding to the depth of the seating surface 1, as shown in Figures 2(c) and 4(a) and (b). Other metal materials can be used for the second metal fitting 4 as long as they are capable of elastically deforming in response to deformation of the seating surface 1. The second metal fitting 4 also has insertion holes for threaded members N2, such as bolts and screws, formed in accordance with the attachment positions of the multiple leg members 2 and the first metal fitting 3. In this embodiment, the second metal fitting 4 is attached by inserting a threaded member into the core material 22 of the leg member 2 from above the second metal fitting 4 (not shown).
［3-4］脚部材の底部構造
上記脚部材２の底部に関しては、本実施形態では図２(b)(c)に示すように脚部材２の底面側に平板状のステンレス製の据付用金具23を取り付けて構成している。この据付用金具23をアンカーボルトや杭部材で地面Ｇや床面に固定することによってベンチＢを設置場所に固定することができる。また据付用金具23を芯材22に固定することで芯材22からの荷重を据付用金具23で受けることができる。据付用金具23を複数の脚部材２を掛け渡すように取り付けることで脚部材２の連結も行うことができる。この据付用金具23にはキャスター等を付設してベンチＢを移動可能に構成することもできる。
[3-4] Bottom Structure of Leg Members In this embodiment, the bottom of the leg member 2 is configured by attaching a flat stainless steel mounting bracket 23 to the bottom side of the leg member 2, as shown in Figures 2(b) and 2(c). The bench B can be fixed to the installation location by fixing this mounting bracket 23 to the ground G or floor with anchor bolts or stakes. In addition, by fixing the mounting bracket 23 to the core member 22, the mounting bracket 23 can bear the load from the core member 22. The leg members 2 can also be connected by attaching the mounting bracket 23 so that it spans multiple leg members 2. Casters or the like can be attached to this mounting bracket 23 to make the bench B movable.
［3-5］脚部材の数及び配置
上記脚部材２の数や配置に関しては、脚部材２の材質や形状に応じて適宜変更することができ、少なくとも座面部１の左右両側（好ましくは四隅）、またはその近傍位置に脚部材２が取り付けられていればよい。また座面部１の左右幅が大きい場合には、左右中間位置に脚部材２を取り付けることもできる。
[3-5] Number and arrangement of leg members The number and arrangement of the leg members 2 can be changed as appropriate depending on the material and shape of the leg members 2, and it is sufficient that the leg members 2 are attached to at least both the left and right sides (preferably the four corners) of the seat portion 1, or positions in the vicinity thereof. Furthermore, if the width of the seat portion 1 is large, the leg members 2 can also be attached to the middle position between the left and right sides.
上記第二金具４は、座面部１の左右内側に突き出した状態でそれぞれの脚部材２に取着している。座面部１の左右幅が大きい場合には、脚部材２及び第二金具４を座面部１の左右中間位置に取り付けることもでき、その場合にも第二金具４の突出部位41が座面部１の左右内側を向くように取り付けるのが好ましい。また本実施形態では、図４(a)に示すように座面部１と第一金具３のネジ留め部の左右外側の位置で、第二金具４の突出部位41と第一金具３（および座面部１）のネジ留めを行って第二金具４を取り付けている。 The second metal fittings 4 are attached to the respective leg members 2 while protruding to the left and right inside of the seat portion 1. If the left and right width of the seat portion 1 is large, the leg members 2 and second metal fittings 4 can be attached to the middle position of the seat portion 1, and in this case, it is preferable to attach the second metal fittings 4 so that the protruding portions 41 face the left and right inside of the seat portion 1. In this embodiment, the second metal fittings 4 are attached by screwing the protruding portions 41 of the second metal fittings 4 to the first metal fitting 3 (and seat portion 1) at positions on the left and right outside of the screw fastening portions of the seat portion 1 and first metal fitting 3, as shown in Figure 4(a).
［４］第一金具および第二金具の機能
上記の構成を採用したことにより、第一金具３で座面部１の各桟材11を連結一体化することができ、更に第一金具３の櫛歯部32(切欠き部31を備えた片側部位)と非櫛歯部33(切欠き部31のないもう一方の片側部位)の下方に脚部材２を選択的に取り付けることができるため、脚部材２の左右方向の取り付け位置を調整することができる。更に左右幅の異なる第二金具４を使用することにより脚部材２の左右方向の取り付け位置の調整も行える。ベンチＢの座面部１への荷重で桟材11が撓んだ場合でも、第二金具４の弾性変形でネジ留め部への負荷を吸収できるため、脚部材２のネジ留め部の破損が生じ難い。
[4] Functions of the First and Second Metal Fittings By adopting the above configuration, the first metal fitting 3 can connect and integrate each crosspiece 11 of the seat portion 1, and further, the leg members 2 can be selectively attached to the underside of the comb-tooth portion 32 (the portion on one side with the notch portion 31) and the non-comb-tooth portion 33 (the portion on the other side without the notch portion 31) of the first metal fitting 3, making it possible to adjust the left-right attachment position of the leg members 2. Furthermore, by using second metal fittings 4 with different left-right widths, the left-right attachment position of the leg members 2 can also be adjusted. Even if the crosspieces 11 are deflected by the load on the seat portion 1 of the bench B, the elastic deformation of the second metal fitting 4 can absorb the load on the screw-fastening portion, making it less likely that the screw-fastening portion of the leg members 2 will break.
『第二実施形態』
[１]基本構成について
次に本発明の第二実施形態について図５～図８に基づいて説明する。本実施形態のベンチＢにおいては、図５、図６(a)(b)(c)および図７(a)(b)に示すように、座面と平行に形成された底辺部24、底辺部24の両側が上方に立ち上がった立上り部25、および立上り部25の上端が内側に折れ曲がった折返し部26を有する上側が開口したＣ型形状の脚部材２を使用している。そして、図８に示すように脚部材２の折返し部26および第一金具３に形成されたネジ孔Ｈ4・Ｈ2にネジ部材Ｎ4を挿通することで、脚部材２を第一金具３の非櫛歯部33の両端(座面部１の奥行き方向の両端)に止着している。これにより環状の脚部材２を使用する場合よりもベンチを軽量化することができる。その他の構成要件については、第一実施形態と同様である。
Second Embodiment
[1] Basic Configuration Next, a second embodiment of the present invention will be described with reference to FIGS. 5 to 8. As shown in FIGS. 5, 6(a), 6(b), 6(c), and 7(a) and 7(b), the bench B of this embodiment uses a C-shaped leg member 2 with an open top, including a base portion 24 formed parallel to the seat surface, rising portions 25 extending upward from both sides of the base portion 24, and a folded portion 26 where the upper end of the rising portion 25 is bent inward. As shown in FIG. 8, the leg member 2 is fastened to both ends of the non-tooth portion 33 of the first fitting 3 (both ends in the depth direction of the seat surface 1) by inserting a screw member N4 through the folded portion 26 of the leg member 2 and the screw holes H4 and H2 formed in the first fitting 3. This allows the bench to be lighter than when an annular leg member 2 is used. Other structural features are the same as those of the first embodiment.
上記のように第一金具３の非櫛歯部33の下方に脚部材２を取り付ける場合でも、図６(a)(b)(c)に示すように座面部１の左右外側に第一金具の櫛歯部32が存在することで、座面部１の各桟材11の隙間から第一金具３が露出することもないため、ベンチＢを上側から見た際の外観が損なわれることもない。また本実施形態では第一金具３と座面部１の止着と、脚部材２と座面部１の止着を別個に行っているが、脚部材２の折返し部26と第一金具３を座面部１に一緒に止着することもできる。また上記脚部材２の底辺部24をアンカーボルトや杭部材で地面Ｇや床面に固定すればベンチＢを設置場所に固定できる。 Even when the leg member 2 is attached below the non-tooth portion 33 of the first metal fitting 3 as described above, the presence of the tooth-like portions 32 of the first metal fitting on the left and right outer sides of the seat portion 1, as shown in Figures 6(a), (b), and (c), prevents the first metal fitting 3 from being exposed through the gaps between the crosspieces 11 of the seat portion 1, and therefore does not impair the appearance of the bench B when viewed from above. In this embodiment, the first metal fitting 3 is fastened to the seat portion 1 and the leg member 2 is fastened to the seat portion 1 separately, but the folded portion 26 of the leg member 2 and the first metal fitting 3 can also be fastened to the seat portion 1 together. Furthermore, the bench B can be secured to its installation location by fastening the base portion 24 of the leg member 2 to the ground G or floor with anchor bolts or stakes.
[２]脚部材について
上記脚部材２については、本実施形態では図５及び図７(a)(b)に示すようにステンレス板を台形型に曲げ加工したものを使用しているが、脚部材２の材料に関しては所定の剛性を有する材料であればその他の金属材料やプラスチック材料、複合材料を適宜選択して使用できる。また脚部材２の形状に関しては、Ｃ型形状であれば台形状である必要はなく、底辺部24と立上り部25が直角を成すコの字型の形状や、立上り部25が湾曲した形状を採用することもできる。脚部材２の厚みや左右幅については、必要となる強度に応じて適宜変更できるが、左右幅は第一金具３の非櫛歯部33に合わせて形成できる。
[2] Regarding the Leg Members In this embodiment, the leg members 2 are made by bending a stainless steel plate into a trapezoidal shape as shown in Figures 5 and 7(a) and (b). However, the material for the leg members 2 can be selected appropriately from other metal materials, plastic materials, and composite materials as long as they have the required rigidity. Furthermore, the shape of the leg members 2 does not have to be trapezoidal as long as it is C-shaped; a U-shape in which the base portion 24 and the rising portion 25 form a right angle, or a shape in which the rising portion 25 is curved, can also be used. The thickness and left-right width of the leg members 2 can be changed appropriately depending on the required strength, but the left-right width can be formed to match the non-tooth portion 33 of the first fitting 3.
上記Ｃ型の脚部材２は、金属板を曲げ加工したもの、或いはプラスチック等を一体成形したものを使用するのが好ましいが、複数の板材や棒材を溶接やネジ留めなどによってＣ型に連結したものを使用することもできる。また本実施形態では、第一実施形態と同様、奥行方向に複数の中空部を有する桟材11を使用し、更に図８に示すように奥行き方向の内側の中空部に芯材13を挿入することで、脚部材２と座面部１を連結するネジ部材Ｎ4が芯材13に干渉しないようにしている。更に本実施形態では、図７(a)に示すように上記脚部材２の折返し部26の端部に凹部26aを形成することで、第一金具３と座面部１を止着するネジ部材Ｎ1に折返し部26が干渉しないようにしている。 The C-shaped leg member 2 is preferably made of a bent metal plate or a single-piece molded plastic, but it can also be made of multiple plates or rods connected to a C shape by welding or screwing. Similar to the first embodiment, this embodiment uses a crosspiece 11 having multiple hollows in the depth direction, and as shown in Figure 8, a core member 13 is inserted into the inner hollows in the depth direction to prevent the screw member N4 connecting the leg member 2 to the seat portion 1 from interfering with the core member 13. Furthermore, in this embodiment, as shown in Figure 7(a), a recess 26a is formed at the end of the folded portion 26 of the leg member 2 to prevent the folded portion 26 from interfering with the screw member N1 fastening the first fitting 3 to the seat portion 1.
