Description

本発明は一般住宅などの居室の壁に取り付けられて必要に応じて手前に組み起こして使用することができるようにした折り畳み机に関するものである。 The present invention relates to a folding desk that is attached to a wall of a living room such as a general house so that it can be used by being raised to the front as required.

従来から、不使用時には畳んでコンパクトにして場所を占めないようにし、使用するときには脚を開きその上に天板を乗せ置くことで机となる折り畳み机が提案されている。例えば、折り畳み机の一つとして特許文献１に示されているように、箱体の前面における開放口の両側辺に脚を回動可能に連結するとともに、前記箱体の開放口の上辺に天板を回動可能に連結したものがあり、箱体側に折り込まれた脚に、箱体上辺に連結した天板が重なることでコンパクトな形態とし、また、天板を一旦跳ね上げてから脚それぞれを箱体の前方に回動させ、その脚の上に前記天板を乗せ置くことで、一対の脚で天板を支持する机を組み起こす技術が提案されている。
また、特許文献２に示されているように、一方のパイプ脚を回動させると他方のパイプ脚も連動して回動するようにし、そして、パイプ脚の回動中心部分に突起を設けて、その突起を脚支持部の斜めスリットに沿わせることで、パイプ脚が回動するに従って床に接触し、回動する脚が床を擦って傷を付けるということが生じないようにした工夫が提案されている。
実開昭５８−１２６７３２号公報実公昭４１−０２４７６０号公報 2. Description of the Related Art Conventionally, folding desks have been proposed that are folded to be compact when not in use so that they do not occupy space, and when used, a leg is opened and a top plate is placed thereon to form a desk. For example, as shown in Patent Document 1 as one of the folding desks, legs are rotatably connected to both sides of the opening on the front surface of the box, and a ceiling is attached to the upper side of the opening of the box. There is a plate that is pivotably connected, and the top plate connected to the upper side of the box overlaps with the leg folded to the box side, so that it has a compact form. There has been proposed a technique for assembling a desk that supports a top plate with a pair of legs by rotating each of them in front of a box and placing the top plate on the legs.
Further, as shown in Patent Document 2, when one pipe leg is rotated, the other pipe leg is also rotated in conjunction with it, and a protrusion is provided at the center of rotation of the pipe leg. , By arranging the protrusion along the diagonal slit of the leg support part, the pipe leg comes into contact with the floor as it rotates, so that the rotating leg does not rub against the floor and scratch it. Proposed.

しかしながら、折り畳み机の脚が回動に伴なって徐々に下がって床面に接触するようにした上記構造では、脚の下端がその床面に接触しても僅かな距離ではあるが、やはり移動しながら床面を擦っており、そのため、擦り傷を確実に防止できないものであった。そして、脚にキャスターを取り付けてこのキャスターの車輪が転がりながら床面に接触する構成としたものも提案されているが、キャスターの移動痕が床面に付いてしまい、床面の体裁を大きく損なうことも問題とされている。
そこで本発明は回動可能とした脚により天板を支持する構造の折り畳み机において、乗せ置かれる天板を適正に支持する位置まで脚を引き出しても、天板が乗せ置かれるまでは床面に接触しないようにする構造とすることを課題とし、この折り畳み机を設置した床面に、脚の回動による擦り傷を生じさせないことを目的とするものである。 However, in the above structure in which the legs of the folding desk are gradually lowered with the rotation and come into contact with the floor surface, even if the lower end of the leg contacts the floor surface, it is still a short distance, but still moves. However, the floor surface was rubbed, and therefore, scratches could not be reliably prevented. A caster is attached to the leg so that the wheels of the caster are in contact with the floor surface while rolling, but the caster's movement marks are attached to the floor surface, which greatly impairs the appearance of the floor surface. This is also a problem.
Therefore, in the folding desk having a structure in which the top plate is supported by a leg that can be rotated, the floor surface until the top plate is placed even if the leg is pulled out to a position that properly supports the top plate to be placed. The object of the present invention is to prevent a scratch caused by the rotation of the legs on the floor surface on which the folding desk is installed.

本発明は上記課題を考慮してなされたもので、壁体に組み付けられた折り畳み机であって、前記壁体に固定の上横板と下横板とからなる支持部に壁体側から壁体前方に向けて観音開き状に回動可能に連結された一対の脚と、前記支持部の上横板に上下方向に回動可能に連結され、壁体前方に回動した前記脚の上に配置可能な天板とを備えた折り畳み机において、前記支持部と脚との連結部分に、脚上に天板を乗せ置いたときに前記脚が降下する押圧力で脚を上方に向けて押圧して、前記天板が乗せ置かれていないときの脚の下端を机設置床から離間させる付勢手段が設けられていることを特徴とする折り畳み机を提供して、上記課題を解消するものである。 The present invention has been made in consideration of the above-mentioned problems, and is a folding desk assembled to a wall body, the wall body from the wall body side to a support portion composed of an upper horizontal plate and a lower horizontal plate fixed to the wall body. A pair of legs that are pivotably connected in a double-spread manner toward the front, and an upper horizontal plate that is pivotally connected to the upper horizontal plate of the support portion, and is disposed on the legs that are rotated forward of the wall. In a folding desk equipped with a possible top plate, the leg is pressed upward by the pressing force that the leg descends when the top plate is placed on the leg at the connecting part of the support part and the leg. And providing a folding table characterized in that a biasing means is provided for separating the lower end of the leg when the top plate is not placed on the table from the desk installation floor. is there.

本発明によれば、壁体の前方に回動した脚に天板が乗せ置かれるまでその脚の下端が机設置床に接触しないため、机設置床に従来のような擦り傷を付けることがなく、床面の体裁を損なうことがないなど、実用性に優れた効果を奏するものである。 According to the present invention, the lower end of the leg does not contact the desk installation floor until the top plate is placed on the leg rotated in front of the wall body, so that the desk installation floor is not scratched conventionally. It has an excellent practicality effect, for example, it does not impair the appearance of the floor surface.

つぎに本発明を図１から図７に示す実施の形態に基づいて説明する。
図中１は一般住宅において多用途に利用できる作業空間を形成する壁体２に組み付けられた折り畳み机を示している。図２に示されているように前記壁体２を平断面形状が略コ字状となるように設けられていて、作業空間の間口方向に沿った面の壁体２に、その間口方向に沿って二つの折り畳み机１を並設するようにして組み付けた例が図示されている。以下は一方の折り畳み机１の説明であるが、他方の折り畳み机１においても同様である。 Next, the present invention will be described based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a folding desk assembled to a wall 2 that forms a work space that can be used for various purposes in a general house. As shown in FIG. 2, the wall body 2 is provided so that the plane cross-sectional shape is substantially U-shaped, and the wall body 2 on the surface along the frontage direction of the work space is provided in the frontage direction. An example is shown in which two folding desks 1 are assembled so as to be arranged side by side. The following is a description of one folding desk 1, but the same applies to the other folding desk 1.

図１から図３に示されているように折り畳み机１は、上記間口方向の面における壁体２と一体として形成された支持部３と、この支持部３に連結されている天板４と、同じく前記支持部３に連結されている一対の脚５とを備えてなるものである。
まず、支持部３は、通常の机高さ程度としてこの折り畳み机１の机設置床（仕上げ床）Ｃから約６７ｃｍの高さ位置に上横板６を間口方向に亘って設け、その上横板６から床（構造体の床、例えばスラブ）までに化粧板７を取り付け、さらに前記化粧板７の前面（室内側）であって前記上横板６から下方に所定距離で離れた位置に上横板６と平行にして下横板８を間口方向に亘って設けたものである。
なお、図示したこの実施の形態において、上横板６、化粧板７、下横板８からなる支持部３は上記作業空間の間口方向の全長に亘っていて、二つの折り畳み机１ごとに分断はされておらず、一体となっている。また図においてａは化粧壁であり、図２において説明を容易にするために化粧壁は図示していない。 As shown in FIG. 1 to FIG. 3, the folding desk 1 includes a support portion 3 formed integrally with the wall body 2 on the surface in the frontage direction, and a top plate 4 connected to the support portion 3. Similarly, it comprises a pair of legs 5 connected to the support part 3.
First, the support unit 3 is provided with an upper horizontal plate 6 at a height of about 67 cm from the desk installation floor (finishing floor) C of the folding desk 1 as a normal desk height, across the frontage direction. A decorative board 7 is attached from the board 6 to the floor (the floor of the structure, for example, a slab), and further on the front surface (interior side) of the decorative board 7 at a position spaced apart from the upper horizontal board 6 by a predetermined distance. A lower horizontal plate 8 is provided across the front opening in parallel with the upper horizontal plate 6.
In the illustrated embodiment, the support portion 3 including the upper horizontal plate 6, the decorative plate 7, and the lower horizontal plate 8 extends over the entire length in the frontage direction of the work space, and is divided into two folding tables 1. It is not done and is united. In the figure, a is a decorative wall, and the decorative wall is not shown in FIG. 2 for ease of explanation.

天板４は上記上横板６の前縁にヒンジ９を介して回動可能に連結されていて、上横板６から下垂した状態とすることができるとともに、下垂した天板４を引き起こして水平状態位置を経て、さらに天板前縁がやや上方に位置する前上がりの傾斜状態となる範囲で回動できるものである（図６参照）。天板４を水平としたときに、相対する天板４の前記上横板６側の端面と上横板６の前端面との間には隙間が存在しており、そのため、前述したように天板４が水平状態位置を経て天板４の手前が前上がりする傾斜状態とすることができる。
脚５は左右一対とされ、それぞれが間口方向の壁体２の前方に向けて張り出た状態から上記支持部３に重なるように折り込まれた状態とすることができるように支持部３に回動可能にして連結されている。即ち、一対の脚５が観音開き状にして開け閉めできるものであり、一対の脚５が支持部３に折り込まれている状態のときに天板４をその脚５側に重なるようにして折り重ねられ、また、天板４を引き起こして水平状態や前上がりした状態で一対の脚５を回動させることができる。 The top plate 4 is pivotally connected to the front edge of the upper horizontal plate 6 via a hinge 9 so that the top plate 4 can be suspended from the upper horizontal plate 6. After passing through the horizontal state position, the top plate front edge can be rotated in a range where it is in a forwardly rising and inclined state (see FIG. 6). When the top plate 4 is horizontal, there is a gap between the end surface of the opposite top plate 4 on the side of the upper horizontal plate 6 and the front end surface of the upper horizontal plate 6, and as described above, The top plate 4 can be in an inclined state in which the front side of the top plate 4 rises forward through the horizontal state position.
The legs 5 are a pair of left and right, and each of the legs 5 is turned to the support portion 3 so as to be folded from the state protruding toward the front of the wall 2 in the frontage direction so as to overlap the support portion 3. It is movable and connected. That is, the pair of legs 5 can be opened and closed in the form of double doors, and when the pair of legs 5 is folded into the support portion 3, the top plate 4 is folded so as to overlap the leg 5 side. In addition, the pair of legs 5 can be rotated in a horizontal state or in a state where the top plate 4 is raised and moved forward.

脚５は、図４に示すように上横板６と下横板８との間に位置し、この脚５の回転中心となる軸材１０と、天板４を脚上に乗せ置いたときに机設置床Ｃの上に立って天板４をほぼ水平に支持する長さとされた脚材１１との間に、横材１２を上下二段にして渡した構造を有している。
そして、前記軸材１０にあっては、その長手方向（上下方向）の寸法を、上横板６の下面と下横板８の上面との距離より僅かに小さくしてその上横板６と下横板８との間で上下方向に移動可能とされ、さらには軸材１０の上端面と下端面とのそれぞれから軸材長手方向に突出したボス１３を、上横板６の下面と下横板８の上面とにある軸受穴１４に入れている。このようにして脚５それぞれは支持部３に回動可能にして連結されているとともに、上下方向に移動可能に設けられている。 The leg 5 is located between the upper horizontal plate 6 and the lower horizontal plate 8 as shown in FIG. 4, and the shaft 10 serving as the rotation center of the leg 5 and the top plate 4 are placed on the leg. In addition, the cross member 12 has a structure in which the cross member 12 is passed in two steps up and down between the leg member 11 standing on the desk installation floor C and having a length for supporting the top plate 4 substantially horizontally.
In the shaft member 10, the dimension in the longitudinal direction (vertical direction) is slightly smaller than the distance between the lower surface of the upper horizontal plate 6 and the upper surface of the lower horizontal plate 8. A boss 13 that is movable in the vertical direction with respect to the lower horizontal plate 8 and that protrudes in the longitudinal direction of the shaft material from each of the upper end surface and the lower end surface of the shaft material 10 is provided below the lower surface of the upper horizontal plate 6. It is put in a bearing hole 14 on the upper surface of the horizontal plate 8. In this way, each leg 5 is rotatably connected to the support portion 3 and is provided so as to be movable in the vertical direction.

さらに、支持部３と脚５との連結部分において、図７に示すように下横板８の軸受穴１４には、上記軸材１０の下端のボス１３に対応位置し、軸材１０を押圧して脚５全体を上方に向けて押し上げるスプリングからなる付勢手段１５が組み込まれており、天板４が脚５の上に乗せ置かれていない状態で前記付勢手段１５での脚５の押し上げにより脚５の下端のアジャスタ１６が机設置床Ｃから離間し、その離間距離は数ｍｍ程度に設定されている。
付勢手段１５の押し上げによって軸材１０の上端が上横板６に当接して位置決めされていて、この脚５を回動させても脚下端が机設置床Ｃと接触することはなく（図６参照）、机設置床Ｃに擦り傷を付けることがない。
脚材１１の下端のアジャスタ１６は回転操作により上下に移動させることができるものであり、通常の机と同様にこのアジャスタの回転操作により脚５に乗せ置いたときの天板４の水平度合いを調整するものである。 Further, at the connecting portion between the support portion 3 and the leg 5, as shown in FIG. 7, the bearing hole 14 of the lower horizontal plate 8 is positioned corresponding to the boss 13 at the lower end of the shaft member 10 and presses the shaft member 10. The urging means 15 comprising a spring that pushes up the entire leg 5 upward is incorporated, and the leg 5 in the urging means 15 is not placed on the leg 5. The adjuster 16 at the lower end of the leg 5 is separated from the desk installation floor C by pushing up, and the separation distance is set to about several mm.
By pushing up the urging means 15, the upper end of the shaft member 10 is positioned in contact with the upper horizontal plate 6, and even if the leg 5 is rotated, the lower end of the leg does not contact the desk installation floor C (see FIG. 6), the desk installation floor C is not scratched.
The adjuster 16 at the lower end of the leg 11 can be moved up and down by a rotation operation, and the level of the top plate 4 when placed on the leg 5 by the rotation operation of the adjuster as in a normal desk. To be adjusted.

脚５を押し上げる付勢手段１５の押圧力はその脚５の上に天板４を乗せ置いたときに脚５が降下する大きさとしていて、折り畳まれてコンパクトになっている折り畳み机１の天板４を引き上げて水平状態よりや手前側を上げた傾斜状態とし、そして、一対の脚５を観音開き状に引き出して天板４の側部に対応する位置まで回動させて引き出し、その後天板４を脚５の上に乗せ置いたときにその脚５が降下して脚材下端の上記アジャスタ１６が机設置床Ｃに接触する（図４参照）。
乗せ置かれた天板４を脚５で支持している状態からその天板４をやや前上がり状態で少し持ち上げれば、脚５が上昇して下端（アジャスタ１６）が机設置床Ｃから離れ、下端が机設置床Ｃから離間した状態のまま脚５を支持部３側に折り畳んで天板４を倒すことで、折り畳み机１がコンパクトになる。図１と図２との二つの折り畳み机１において左側の折り畳み机１は脚５を支持部３側に回動させて天板４を降ろした状態が示されている。 The pressing force of the urging means 15 that pushes up the leg 5 is such that the leg 5 is lowered when the top plate 4 is placed on the leg 5, and the top of the folding desk 1 that is folded and compact is used. The plate 4 is pulled up to be in a tilted state where the front side is raised from the horizontal state, and the pair of legs 5 are pulled out in a double-spreading manner and rotated to a position corresponding to the side portion of the top plate 4, and then the top plate When 4 is placed on the leg 5, the leg 5 descends and the adjuster 16 at the lower end of the leg material comes into contact with the desk installation floor C (see FIG. 4).
If the top 4 is lifted slightly from the state in which the placed top 4 is supported by the legs 5 in a slightly raised state, the legs 5 rise and the lower end (adjuster 16) is separated from the desk installation floor C. The folding desk 1 becomes compact by folding the leg 5 to the support part 3 side and tilting the top 4 while the lower end is separated from the desk installation floor C. In the two folding desks 1 of FIG. 1 and FIG. 2, the left folding desk 1 is shown in a state in which the legs 5 are rotated toward the support part 3 and the top plate 4 is lowered.

なお、天板４と支持部３との間に伸縮可能なダンパーを掛け渡し、天板４の降ろしに際してそのダンパーが徐々に収縮して天板４から手を離しても急激に倒れ込まないようにすることが良好である。また、脚５に天板４を乗せ置くに際して、天板４に対する水平方向で脚５の位置決めをするために、その天板４の裏面の所定位置に脚材１１の上端が入る浅い位置決め用の凹部などを設けることが良好である。さらに上記付勢手段１５は脚５の回動に支障なく脚下端を机設置床から離間させ、天板を乗せ置いたときに脚下端が前記床に接触するようになればよいものであり、図示の実施の形態に限定されるものではない。 It should be noted that an extendable damper is stretched between the top plate 4 and the support portion 3 so that when the top plate 4 is lowered, the damper gradually contracts and does not fall suddenly even if the hand is released from the top plate 4. It is good to make. Further, when placing the top plate 4 on the leg 5, in order to position the leg 5 in the horizontal direction with respect to the top plate 4, shallow positioning for the upper end of the leg material 11 to enter a predetermined position on the back surface of the top plate 4. It is preferable to provide a recess or the like. Further, the urging means 15 should be such that the lower end of the leg is separated from the desk installation floor without hindering the rotation of the leg 5, and the lower end of the leg comes into contact with the floor when the top plate is placed. The present invention is not limited to the illustrated embodiment.
