Description

本考案は、分解状態及び組立状態のいずれにおいても、スタッキング（積み重ね）を可能とする学校用机に関する。 The present invention relates to a school desk that can be stacked in both the disassembled state and the assembled state.

従来、分解状態（各部品ごとの状態）、組立状態（製品の状態）のいずれかの状態でスタッキングが可能な種々の学校用机が公知である。
上記したもののうち、組立状態でのみスタッキングが可能な学校用机は、分解状態ではスタッキングできないため、分解した状態での保管時、輸送時の省スペース性が悪い欠点がある。保管時、輸送時の省スペース性の悪さは、管理コストの増加に直接影響を与えるため非常に問題である。 2. Description of the Related Art Conventionally, various school desks that can be stacked in either a disassembled state (state for each part) or an assembled state (product state) are known.
Among the above, school desks that can be stacked only in the assembled state cannot be stacked in the disassembled state, so that there is a disadvantage that the space saving property during storage and transportation in the disassembled state is poor. The poor space saving at the time of storage and transportation is a serious problem because it directly affects the increase in management cost.

一方、分解状態でのみスタッキング可能な学校用机は、部品ごとに安定した状態でまとめて輸送できるため、納入時の輸送の手間は大幅に低減できるが、組立状態でのスタッキングが不可能であるため、注文を受ける前に組立を行うことは省スペース性を損なうこともあり行えず、注文後に組立を行う必要が生じ、顧客に対して迅速に納入することができない点で不便であった。 On the other hand, school desks that can be stacked only in the disassembled state can be transported together in a stable state for each part, so the labor of transportation at the time of delivery can be greatly reduced, but stacking in the assembled state is impossible. Therefore, assembling before receiving an order cannot be performed because the space-saving property is impaired, and it is necessary to assemble after ordering, which is inconvenient in that it cannot be promptly delivered to a customer.

また、納入後、例えば教室内の掃除や学校行事等において、教室内の多数の学校用机を教室の隅等へ寄せたり、教室外へ移動させたりする際などには、当該学校用机は嵩張ることから、非常に不都合が多い。 In addition, after delivery, for example, when a large number of school desks in the classroom are moved to the corner of the classroom or moved outside the classroom, for example, during classroom cleaning or school events, the school desk It is bulky and very inconvenient.

以上のような欠点を解消するものとして、分解状態及び組立状態のいずれにおいてもスタッキングが可能となる学校用机、例えば、略逆Ｖの字状をなす一対の脚杆を互いに両側に間隔を存して相対向配置し、且つその両脚杆の頂部の各々の内側に天板受金物を設けるとともに、その天板受金物の稍々下方に位置して上記両脚杆相互間に連結杆を横架し、さらに両脚杆の下端方寄り部に手前方を開放した平面コ字形状の足掛杆を該両脚杆の各前後脚杆部の外側に配すべく取付けて構成した机脚と、これを組立ててなる学校用机（例えば、特許文献１参照。）が公知である。 In order to eliminate the drawbacks described above, a school desk that can be stacked in both the disassembled state and the assembled state, for example, a pair of leg lamps having a substantially inverted V shape are spaced apart from each other. In addition, the top plate receiver is provided inside each top of the both leg ridges, and a connecting rod is placed between the two leg ridges so as to be positioned below the top plate receiver. Furthermore, a table leg formed by attaching a flat U-shaped foot rod with the front of the hand to the lower end portion of both leg rods so as to be arranged on the outside of the front and rear leg rod portions of the both leg rods, and An assembled school desk (see, for example, Patent Document 1) is known.

実開昭５４−３８５０２号Shokai 54-38502

しかしながら、上記特許文献１に係る学校用机は、机脚が予め、略逆Ｖの字状をなす一対の脚杆を互いに両側に間隔を存して相対向配置し、且つその両脚杆の頂部の各々の内側に天板受金物を設けるとともに、その天板受金物の稍々下方に位置して上記両脚杆相互間に連結杆を横架し、さらに両脚杆の下端方寄り部に手前方を開放した平面コ字形状の足掛杆を該両脚杆の各前後脚杆部の外側に配すべく取付けた構成であり、机脚のみをスタッキングする際には何ら問題も生じないが、組立てた状態では、学校用机と椅子を組み合わせなければスタッキングができない欠点があった。この組立てた状態のスタッキングは非常に複雑であり、納入後においては実用的でないばかりか、例えば学生等不慣れな者が行う場合にはスタッキングを行った学校用机及び椅子が崩落する危険を伴うものであった。 However, in the school desk according to the above-mentioned Patent Document 1, the table legs are arranged in advance so that a pair of leg rods having a substantially inverted V shape are arranged opposite to each other with a gap between the two sides. A top plate receiver is provided on the inner side of each of the two, and a connecting rod is horizontally placed between the two leg rods at a position below the top plate receiver, and further, the front of the hand is placed near the lower end of both leg rods. This is a structure in which flat U-shaped foot rods with open arms are attached to the outside of the front and rear leg flanges of both leg rods, and there is no problem when stacking only the table legs. However, there was a drawback that stacking would not be possible without combining a school desk and chair. Stacking in this assembled state is very complicated and is not practical after delivery. For example, when an unfamiliar person such as a student performs it, there is a risk that the school desk and chair where the stacking was performed will collapse. Met.

本考案は、以上の事情に鑑みてなされたものであり、分解状態、組立状態のいずれにおいても、学校用机のみをスタッキング可能で、分解状態での保管時、輸送時の管理コストを低減でき、製品完成後には、椅子と組み合わせなくとも机だけで簡単且つ安全にスタッキングができ、納入業者や学生の便宜に資することができる学校用机を提供することを、考案が解決しようとする課題とする。 The present invention has been made in view of the above circumstances, and it is possible to stack only school desks in both the disassembled state and the assembled state, and the management cost during storage and transportation in the disassembled state can be reduced. After the product is completed, the idea is to solve the problem of providing a school desk that can be easily and safely stacked without using a chair and can be used for the convenience of suppliers and students. To do.

天板と、収納部と、フレームとからなり、フレームのみのスタッキングと、組立状態でのスタッキングの双方が可能な学校用机において、フレームは、相互に対向する右枠と左枠の夫々の上部の一端を中央連結杆で連結し、前記右枠と左枠は、夫々、並行する前脚杆及び後脚杆の上端相互を側部連結杆で連結してなり、前脚杆と後脚杆は、正面視同一軸線上に位置せず、且つ平面視において天板内に収まることを特徴とする学校用机を、課題を解決するための手段とするものである。 In a school desk consisting of a top plate, a storage unit, and a frame, and stacking only the frame and stacking in the assembled state, the frame is the upper part of each of the right and left frames facing each other. The right frame and the left frame are connected to each other at the upper ends of the parallel front and rear leg joints with side connection hooks. A school desk that is not located on the same axis line as viewed from the front and that fits within the top plate in plan view is used as a means for solving the problem.

天板と、収納部と、フレームとからなり、フレームのみのスタッキングが可能であり、且つ、組立状態でのスタッキングが可能な学校用机において、フレームは、相互に対向する右枠と左枠の夫々の上部の一端を中央連結杆で連結し、前記右枠と左枠は、夫々、並行する前脚杆及び後脚杆の上端相互を側部連結杆で連結してなり、前脚杆と後脚杆は、正面視同一軸線上に位置せず、且つ平面視において天板内に収まることから、二台の学校用机を下面側から前後の向きを相対的に逆向きとして嵌め合わすことで、一方の学校用机の天板裏面に対して他方の学校用机の各前脚杆及び後脚杆の裏面が当接することとなって、安定したスタッキングを行うことができる。 In a school desk consisting of a top plate, a storage section, and a frame, and stacking of only the frame is possible and stacking in an assembled state is possible, the frame has a right frame and a left frame facing each other. One end of each upper part is connected with a central connecting rod, and the right frame and the left frame are respectively connected with the upper ends of parallel front and rear leg rods with side connecting rods. The kite is not located on the same axis as viewed from the front, and fits within the top plate in plan view, so that the two school desks are fitted with the front and back directions relatively opposite to each other, Stable stacking can be performed because the back surfaces of the front and rear leg cages of the other school desk come into contact with the back surface of the top board of one school desk.

また、請求項２に係る考案のように、上記考案の構成に加えて、前脚杆と後脚杆との間、若しくは左右の前脚杆の間であって、前脚杆及び後脚杆の長手中央よりも上部となる位置に、補助連結杆を設けることにより、フレームの強度を飛躍的に向上するだけでなく、学校用机が組立状態であっても、補助連結杆相互が干渉することが無いから、組立状態でのスタッキングを行うことができる。 Further, as in the invention according to claim 2, in addition to the configuration of the above-mentioned invention, it is between the front leg heel and the rear leg heel, or between the left and right front leg heels, and the longitudinal center of the front leg heel and the rear leg heel. By providing the auxiliary connecting rod in the upper position, not only the strength of the frame is dramatically improved, but even if the school desk is in the assembled state, the auxiliary connecting rod does not interfere with each other Thus, stacking in an assembled state can be performed.

請求項３に係る考案によれば、上記請求項１及び請求項２の構成に加えて、側部の補助連結杆は、側部連結杆よりも長いものとし、側部連結杆と前記補助連結杆の後端部を同一鉛直線上とし、前脚杆のうち、側部連結杆の前端部との交差位置から補助連結杆の前端部との交差位置までの間を、クランク状（即ち、クランク曲げによってＳ字に湾曲した状態）としたことから、クランク状とした部分の強度が向上することで、フレームの右枠及び左枠の捩れを抑えることができ、より一層、フレーム強度を向上することができる。 According to a third aspect of the present invention, in addition to the configurations of the first and second aspects, the side auxiliary connecting rod is longer than the side connecting rod, and the side connecting rod and the auxiliary connecting rod are provided. The rear end of the heel is on the same vertical line, and the front leg heel has a crank shape (i.e., crank bending) from the position where it intersects the front end of the side connection heel to the position where the auxiliary connection heel intersects. Therefore, by improving the strength of the crank-shaped part, it is possible to suppress the twisting of the right and left frames of the frame and further improve the frame strength. Can do.

請求項４に係る考案のように、請求項２若しくは請求項３に係る考案の構成に加えて、補助連結杆の短手方向断面形状は長円形状としたことによって、短手方向断面形状が円形状である場合と比べて、外部からの衝撃を長手方向に形成される平面で受けることができることから、衝撃をより分散させることができ、耐久強度を高めることができる。 As in the device according to claim 4, in addition to the structure of the device according to claim 2 or claim 3, the cross-sectional shape in the short direction of the auxiliary connecting rod is an oval shape. Compared to the case of a circular shape, the impact from the outside can be received by the plane formed in the longitudinal direction, so that the impact can be further dispersed and the durability strength can be increased.

請求項５に係る考案、即ち、上記請求項２乃至請求項４に係る構成に加えて、前脚杆と後脚杆との間、及び左右の前脚杆の間に設ける補助連結杆は、平面視凵字状とし、前脚杆及び後脚杆に溶着した構成とすることによって、組立て容易とすることができるばかりでなく、前脚杆及び後脚杆の内側に配置されることで前脚杆及び後脚杆を補強するとともに、外部からの他物との接触確率を低減し、補助連結杆の傷付きや変形を低減することができる。 In addition to the device according to claim 5, that is, the configuration according to claims 2 to 4, the auxiliary connecting rod provided between the front leg rod and the rear leg rod, and between the left and right front leg rods is a plan view. It is not only easy to assemble by adopting a scissors-like shape and welded to the front and rear leg cages, but it is also arranged inside the front and rear leg cages so that it can be easily assembled. In addition to reinforcing the heel, the probability of contact with other objects from the outside can be reduced, and damage and deformation of the auxiliary connecting ledge can be reduced.

一方、上記請求項５に係る考案とは異なり、請求項６に係る考案のように、前脚杆と後脚杆との間、及び左右の前脚杆の間に設ける補助連結杆は、前脚杆と後脚杆の対向する位置に夫々形成した取付穴部に、当該補助連結杆の両端を嵌入固着した構成とすることによって、取付穴部の縁面が補助連結杆を支持することで、補助連結杆の取付け強度を向上することができる。そして、同構成によれば、請求項５に係る考案の構成と比較して、補助連結間が各前脚杆及び後脚杆の間に配置されることから、収納部の下の空間の使用可能な領域をより広げることができる。 On the other hand, unlike the device according to claim 5, the auxiliary connecting rods provided between the front leg rods and the rear leg rods and between the left and right front leg rods, as in the device according to claim 6, By adopting a configuration in which both ends of the auxiliary connecting rods are fitted and fixed to the mounting hole portions formed at the positions where the rear leg rods are opposed to each other, the edge surfaces of the mounting hole portions support the auxiliary connecting rods.

In addition, since it is the structure which attached the cap 5 made from a synthetic resin to the edge part of the front leg rods 300 and 301 and the rear leg rods 301 and 311 which contact | abut with respect to the lower surface 11 of the top plate 1, the lower surface 11 of the top plate 1 is attached. Can be prevented from being damaged.

スタッキングの状態であっても、平面視において、ら二台の学校用机Ａ（Ａ１、Ａ２）の双方の前脚杆３００、３０１及び後脚杆３０１、３１１は、天板１の周縁から露呈しない。このため、二台一組にスタッキングした学校用机Ａを複数積み上げる際には、前脚杆３００、３０１及び後脚杆３０１、３１１が他の学校用机Ａに干渉することが無く、非常に効率よく、多量の学校用机Ａを積み上げることができる。 Even in the stacking state, the front leg rods 300 and 301 and the rear leg rods 301 and 311 of the two school desks A (A1 and A2) are not exposed from the periphery of the top board 1 in plan view. . For this reason, when stacking a plurality of school desks A stacked in a set of two, the front leg hooks 300 and 301 and the rear leg hooks 301 and 311 do not interfere with other school desks A, which is very efficient. A lot of school desks A can be stacked.

このような前脚杆３００、３０１及び後脚杆３０１、３１１が平面視において前記天板１からはみ出さずに二台一組でスタッキングできる構成は、正面視において前脚杆３００、３０１及び後脚杆３０１、３１１が同一軸線上にないにもかかわらず、天板１は平面視長方形状であるという特別な構成によって得られる。 Such a configuration in which the front leg rods 300 and 301 and the rear leg rods 301 and 311 can be stacked together as a pair without protruding from the top plate 1 in a plan view is the front leg rods 300 and 301 and the rear leg rod in a front view. Despite the fact that 301 and 311 are not on the same axis, the top plate 1 is obtained by a special configuration that is rectangular in plan view.

次に、本実施例１に係る学校用机Ａのパイプフレーム３ａのみのスタッキングについて図７に示す。
スタッキングされる二台の学校用机Ａ（Ａ１、Ａ２）に対応するパイプフレーム３ａ相互の構成について説明する。 Next, FIG. 7 shows stacking of only the pipe frame 3a of the school desk A according to the first embodiment.
The mutual structure of the pipe frames 3a corresponding to the two school desks A (A1, A2) to be stacked will be described.

下側に位置する学校用机Ａ１のパイプフレーム（以下、第一パイプフレーム３ａ１という。）の上に別の学校用机Ａ２のパイプフレーム（以下、第二パイプフレーム３ａ２という。）を積み重ねる。
平面視において、第二パイプフレーム３ａ２の前脚杆は、第一パイプフレーム３ａ１の枠内に位置する。また、第二パイプフレーム３ａ２の後脚杆は、第二パイプフレーム３ａ２の枠外に位置する。第一パイプフレーム３ａ１の側部連結杆３０２、３１２上に第二パイプフレーム３ａ２の側部連結杆３０２、３１２が跨ぐように載置されることとなる。当該構成を順次上方へ重ねることによってスタッキングを行うことができる。 A pipe frame (hereinafter referred to as the second pipe frame 3a2) of another school desk A2 is stacked on the pipe frame (hereinafter referred to as the first pipe frame 3a1) of the school desk A1 located on the lower side.
In plan view, the front leg rod of the second pipe frame 3a2 is located within the frame of the first pipe frame 3a1. Further, the rear leg rod of the second pipe frame 3a2 is located outside the frame of the second pipe frame 3a2. The side connection rods 302 and 312 of the second pipe frame 3a2 are placed across the side connection rods 302 and 312 of the first pipe frame 3a1. Stacking can be performed by sequentially stacking the structures upward.

以上に本考案の実施例１に係る学校用机Ａを示したが、本考案は上記実施例１に限定するものではない。例えば、図８に示すように、補助連結杆の取付構造は、前記実施例１において示した、前脚杆３００、３０１及び後脚杆３０１、３１１の対向する位置に夫々形成した取付穴部３３に両端を嵌入固着した構成に限定するものではなく、例えば、図９に示すように、補助連結杆は、平面視凵字状として前脚杆３００、３０１及び後脚杆３０１、３１１の内側に溶着した取付構造とすることもできる。 Although the school desk A according to the first embodiment of the present invention has been described above, the present invention is not limited to the first embodiment. For example, as shown in FIG. 8, the attachment structure of the auxiliary connecting rod is the mounting hole 33 formed in the position where the front leg rods 300 and 301 and the rear leg rods 301 and 311 face each other as shown in the first embodiment. For example, as shown in FIG. 9, the auxiliary connecting rod is welded to the inside of the front leg rods 300 and 301 and the rear leg rods 301 and 311 as shown in FIG.
