Abstract
A safe leg supporting structure in which foldable legs mounted to the lower surface of a table are totally fixed both in an erected position and in a folded position and in which, particularly in the folded state, a user's hand is not pinched between the table and a leg because the distance between the table and the legs does not change. A first cam surface and a second cam surface, with which cam surfaces a stopper makes contact, are formed on a cam plate integral with a leg. When the leg is erected on the lower surface of a table, a contact member makes contact with a first contact section and the stopper makes contact with the first cam surface, causing the leg to be fixed erected on the lower surface of the table. Also, when the leg is folded along the lower surface of the table, the contact member makes contact with a second contact section and the stopper makes contact with the second cam surface, causing the leg to be fixed folded along the lower surface of the table.

In the table leg support structure as described above, there is a demand to make the structure portion small and the leg space large to be easy to use. Also, when trying to swing the leg or folding it along the bottom of the table, the operator may feel painful because the hands are caught between the leg support structure and the legs and the table. It is necessary not to do it.
In this regard, inPatent Document 1, the leg can be fixed in a state where the leg is set up, but when the leg is folded, there is a possibility that a hand may be caught between the folded leg and the table.
Similarly, inPatent Document 2, when the legs are upright, the legs are fixed and safe. However, when the legs are folded, a circular engagement member simply enters a part of the legs and the legs are Only a groove for easy stopping is formed. Therefore, in this case, when the force is applied to the leg, the engaging member is easily detached from the groove, so that the leg cannot be completely fixed with the leg folded, and the leg moves unexpectedly. Or dangerous.
In addition, there is a risk of fingers touching the movable part when the leg is folded.

また,上記脚が,テーブル下面に沿った折り畳み状態となった時には,上記当り部材が,上記第2の当り部に当接し,且つストッパが,第2のカム面に当接することで,脚は,テーブル下面に沿った折り畳み状態で固定される。
このように,上記脚が,テーブル下面に沿った折り畳み状態となった時には,上記カム板が,当り部材を介して脚支持台に形成された第2の当り部に当接するので,脚は,回動できず,またその状態で,カム板の第2のカム面が,ストッパ支持軸に対して離間できないストッパに当接するので,脚は,畳まれた状態で,完全に強固に固定され,ガタが生じない。従って,脚がテーブル下面に沿う状態に畳まれた時に,脚とテーブル下面との距離が変動しないので,テーブル下面と脚との間に手が挟まれるような危険性が皆無となる。 Since the present invention is configured as described above, when the leg is standing on the lower surface of the table, the contact member abuts on the first contact portion, and the stopper is the first cam. By abutting on the surface, the legs are firmly fixed in a state where they stand on the lower surface of the table.
Thus, since the cam plate contacts the first contact portion formed on the leg support via the contact member, the leg cannot rotate, and in this state, the first cam plate Since the cam surface comes into contact with a stopper that cannot be separated from the stopper support shaft, the leg cannot be rotated. Therefore, the leg is completely fixed in a standing state, and there is no play.
Further, when the leg is folded along the lower surface of the table, the contact member comes into contact with the second contact part, and the stopper comes into contact with the second cam surface, so that the leg , Fixed in a folded state along the lower surface of the table.

また,このようなテーブル用支持脚では,脚支持構造部分をコンパクトにし,下肢空間が広いほど使用者には便利である。そのためには,カム板の形状を小さくし,脚支持軸の中心とカム,ストッパが当接する点との距離を小さくする必要がある。しかし,テーブル使用時に加わる力(脚を折畳み方向に回転させる力,図5に矢印Y1で示す力)を受け止めるカム,ストッパの当接面の負荷はこの距離に反比例して大きくなる。そこで,コンパクトにするには,カム板を2枚にし,ストッパが当接する点も2ヶ所にして,負荷を分散させることが有利である。更には,特許文献2に見られるような,脚が2本連結されている構造ではなく,単独脚の場合は特に,脚支持軸の軸長方向に対して回転させる力(図4にY2で示す)が大きく動く為,この負荷を受け止めるには2枚のカム板を脚支持軸の軸長方向に可能な限り広い間隔で配置して,2枚のカム板,ストッパの当接面の間隔を大きく設定することが有利である。
その点,本発明では,上記カム板が,上記のようにテーブル下面に垂直の2枚の平行なカム板からなっており,上記脚支持台は,上記2枚のカム板と平行で,上記2枚のカム板を内側に挟む構造となっており,上記のような負荷に対して有利である。
加えて,上記脚の回動端部には,湾曲した帯材から構成された保護カバーが固定され,保護カバーは,その両端が上記脚の回動端部に固定され,上記2枚の脚支持台の内側の間隔と略等しい幅に形成されており,少なくとも上記脚支持軸と,カム板と,ストッパとを上記湾曲した空間内に包含している場合には,脚の折り畳み動作に伴って,レバーによってストッパを回動させる動作と,カム板を回動させる動作が生じても,これらの部材が保護カバーに囲まれ,外部に露出することがなく,人の手がその部分に近づくことが出来ないので,人手がこのような可動部分に巻き込まれたり,挟まれたりする危険性が完全に回避される。 Moreover, in such a table support leg, the leg support structure is made compact, and the lower the leg space, the more convenient for the user. For this purpose, it is necessary to reduce the shape of the cam plate and to reduce the distance between the center of the leg support shaft and the point where the cam and stopper come into contact. However, the load applied to the contact surface of the cam and stopper that receives the force applied when the table is used (the force that rotates the legs in the folding direction, the force indicated by the arrow Y1 in FIG. 5) increases in inverse proportion to this distance. Therefore, for compactness, it is advantageous to distribute the load by using two cam plates and two points where the stopper contacts. Furthermore, it is not a structure in which two legs are connected as shown inPatent Document 2, but in the case of a single leg, the force for rotating the leg support shaft in the axial direction (Y2 in FIG. 4). In order to catch this load, the two cam plates should be arranged as wide as possible in the axial direction of the leg support shaft, and the distance between the contact surfaces of the two cam plates and the stopper It is advantageous to set a large value.
In that respect, in the present invention, the cam plate is composed of two parallel cam plates perpendicular to the lower surface of the table as described above, and the leg support is parallel to the two cam plates, and It has a structure in which two cam plates are sandwiched on the inside, which is advantageous for the above loads.
In addition, a protective cover made of a curved strip is fixed to the rotating end of the leg, and both ends of the protective cover are fixed to the rotating end of the leg. When the legs are formed to have a width substantially equal to the inner space of the support base and at least the leg support shaft, the cam plate, and the stopper are included in the curved space, the leg is folded. Therefore, even if the lever is rotated by the lever and the cam plate is rotated, these members are surrounded by the protective cover and are not exposed to the outside, and the human hand approaches that portion. The risk of human hands being caught or trapped in such moving parts is completely avoided.

加えて,上記脚の回動端部には,湾曲した帯材から構成された保護カバーが固定され,保護カバーは,その両端が上記脚の回動端部に固定され,上記2枚の脚支持台の内側の間隔と略等しい幅に形成されており,少なくとも上記脚支持軸と,カム板と,ストッパとを上記湾曲した空間内に包含している場合には,脚の折り畳み動作に伴って,レバーによってストッパを回動させる動作と,カム板を回動させる動作が生じても,これらの部材が保護カバーに囲まれ,外部に露出することがなく,人の手がその部分に近づくことが出来ないので,人手がこのような可動部分に巻き込まれたり,挟まれたりする危険性が完全に回避される。 Moreover, in such a table support leg, the leg support structure is made compact, and the lower the leg space, the more convenient for the user. For this purpose, it is necessary to reduce the shape of the cam plate and to reduce the distance between the center of the leg support shaft and the point where the cam and stopper come into contact.

In addition, a protective cover made of a curved strip is fixed to the rotating end of the leg, and both ends of the protective cover are fixed to the rotating end of the leg. When the legs are formed to have a width substantially equal to the inner space of the support base and at least the leg support shaft, the cam plate, and the stopper are included in the curved space, the leg is folded. Therefore, even if the lever is rotated by the lever and the cam plate is rotated, these members are surrounded by the protective cover and are not exposed to the outside, and the human hand approaches that portion. The risk of human hands being caught or trapped in such moving parts is completely avoided.
更に十分な安全性を考慮するならば,ストッパ支持軸も上記保護カバーの湾曲する内部空間内に包含するようにしても良い。
In consideration of sufficient safety, the stopper support shaft may also be included in the curved internal space of the protective cover.

立てた状態の脚,あるいは畳んだ状態の脚を畳む,あるいは立てる場合には,上記ストッパ支持軸を回動させて,ストッパと第1あるいは第2のカム面との干渉を解除する必要がある。ストッパの解除のためにストッパ支持軸を回動させるためのレバーが設けられることが望ましい。この場合,上記レバーを,操作することで,ストッパを第1あるいは第2のカム面から外し,固定された脚を自由に回動させることができる。また,レバーの操作部は2枚の脚支持台の間に位置すると,構造部がコンパクトにまとまり,下肢空間が広くなり,使い勝手が良い。 The legs must be completely fixed in an upright or folded state. For this purpose, it is necessary to prevent the stopper from coming off the first or second cam surface carelessly. The elastic member for urging the stopper is for this purpose, and the inconvenience of the stopper being removed without permission is avoided.
When the leg in the standing state or the leg in the folded state is folded or stood, it is necessary to rotate the stopper support shaft to release the interference between the stopper and the first or second cam surface. . It is desirable to provide a lever for rotating the stopper support shaft for releasing the stopper.

In this state, the first cam surface 5a of the cam plate 5 abuts against the stopper 15 that cannot be separated from the leg support shaft 11, so that the leg 1 cannot rotate counterclockwise in FIG. The leg 1 is completely fixed in a standing state.
また,上記脚1が,図2に示すように,テーブル下面3aに沿った折り畳み状態となった時には,上記当り部材17が,上記第2の当り部19bに当接し,且つストッパ15が,第2のカム面5bに当接することで,脚1は,テーブル下面3aに沿った折り畳み状態で固定される。
このように,上記脚1が,図2に示すように,テーブル下面3aに沿った折り畳み状態となった時には,上記カム板5が,当り部材17を介して脚支持台9に形成された第2の当り部19bに当接するので,脚1は,図1における反時計方向に回動できず,またその状態で,カム板5の第2のカム面5bが,ストッパ支持軸11に対して離間できないストッパ15に当接するので,脚1は,図1における時計方向にも回動できない。従って,脚1は,畳まれた状態で,完全に固定され,ガタも生じない。 When theleg 1 is folded along the table lower surface 3a, as shown in FIG. 2, the contact member 17 comes into contact with the second contact portion 19b, and the stopper 15 is The leg 1 is fixed in a folded state along the table lower surface 3a by contacting the second cam surface 5b.
Thus, as shown in FIG. 2, when theleg 1 is folded along the table lower surface 3a, the cam plate 5 is formed on the leg support 9 via the contact member 17. 2, the leg 1 cannot rotate counterclockwise in FIG. 1, and in this state, the second cam surface 5 b of the cam plate 5 is against the stopper support shaft 11. Since it contacts the stopper 15 that cannot be separated, the leg 1 cannot rotate clockwise in FIG. Therefore, the leg 1 is completely fixed in the folded state, and no play is generated.
このように,上記脚1が,図2に示すように,テーブル下面3aに沿った折り畳み状態となった時には,上記カム板5が,当り部材17を介して脚支持台9に形成された第2の当り部19bに当接するので,脚1は,図1における反時計方向に回動できず,またその状態で,カム板5の第2のカム面5bが,ストッパ支持軸11に対して離間できないストッパ15に当接するので,脚1は,図1における時計方向にも回動できない。従って,脚1は,畳まれた状態で,完全に固定され,ガタも生じない。 When the
Thus, as shown in FIG. 2, when the
この時,上記ストッパ支持軸11は,その周りに取り付けられた弾性部材の一例である蔓捲きバネ23によって,図1,図2における反時計方向に回動するように常時付勢されており,上記のように脚1を立てた状態,あるいは畳んだ状態では,上記蔓捲きバネ23に付勢されて,ストッパ15が,第1あるいは第2のカム面5aあるいは5bに当接してカム板5(及びこれと一体の脚1)の回動を阻止している。従って,立てた状態の脚1,あるいは畳んだ状態の脚1を畳む,あるいは立てる場合には,上記ストッパ支持軸11を時計方向に回動させて,第1あるいは第2のカム面5aあるいは5bとの干渉を解除する必要がある。そのために,上記ストッパ支持軸11には,レバー25が固定されており,このレバー25を,回動操作することで,操作者は,ストッパ15を第1あるいは第2のカム面5aあるいは5bから外し,上記のように固定された脚1を自由に回動させることができる。
At this time, the stopper support shaft 11 is constantly urged to rotate counterclockwise in FIGS. 1 and 2 by a vine spring 23 which is an example of an elastic member attached around the stopper support shaft 11. In the state where the leg 1 is upright or folded as described above, the stopper 15 is abutted against the first or second cam surface 5a or 5b by being urged by the vine spring 23, and the cam plate 5 (And the leg 1 integral therewith) is prevented from rotating. Therefore, when the leg 1 in the standing state or the leg 1 in the folded state is folded or stood, the stopper support shaft 11 is rotated in the clockwise direction, and the first or second cam surface 5a or 5b. It is necessary to cancel the interference. For this purpose, a lever 25 is fixed to the stopper support shaft 11. By rotating the lever 25, the operator removes the stopper 15 from the first or second cam surface 5a or 5b. The leg 1 fixed as described above can be freely rotated.
上記カム板5は,上記のようにテーブル下面3aに垂直の2枚の平行なカム板5,5からなっており,上記脚支持台9,9は,上記2枚のカム板5,5と平行で,上記2枚のカム板5,5を内側に挟む構造となっている。加えて,上記脚1の回動端部には,湾曲した帯材から構成された保護カバー21が固定されている。この保護カバー21は,その両端に設けられた固定用端部21a,21bが上記脚1の回動端部(或いは,カム板5)に固定されることで,脚1に固定されている。上記保護カバー21は,上記2枚の脚支持板9,9の内側の間隔と略等しい幅に形成されており,少なくとも上記脚支持軸7と,カム板5と,ストッパ15とを上記湾曲した空間内に包含している。
上記保護カバー21は,上述のように,脚支持構造の可動部分に手が触らないことを目的としたもので,それ自身は,上記可動部に接触しても構わないので,接触したときに柔軟に湾曲できるように,柔軟な材質で構成することが望ましい。 Thecam plate 5 is composed of two parallel cam plates 5 and 5 perpendicular to the table lower surface 3a as described above, and the leg support bases 9 and 9 are connected to the two cam plates 5 and 5, respectively. In parallel, the two cam plates 5 and 5 are sandwiched inside. In addition, a protective cover 21 made of a curved strip is fixed to the rotating end of the leg 1. The protective cover 21 is fixed to the leg 1 by fixing end portions 21 a and 21 b provided at both ends thereof to the rotating end portion (or the cam plate 5) of the leg 1. The protective cover 21 is formed to have a width substantially equal to the inner space between the two leg support plates 9, 9, and at least the leg support shaft 7, the cam plate 5, and the stopper 15 are curved. Contained in space.
As described above, theprotective cover 21 is intended to prevent the hand from touching the movable part of the leg support structure, and itself may contact the movable part. It should be made of a flexible material so that it can bend flexibly.
上記保護カバー21は,上述のように,脚支持構造の可動部分に手が触らないことを目的としたもので,それ自身は,上記可動部に接触しても構わないので,接触したときに柔軟に湾曲できるように,柔軟な材質で構成することが望ましい。 The
As described above, the
このような脚支持構造Xでは,脚1の折り畳み動作に伴って,前記レバー25によってストッパ15を回動させる動作と,カム板5を回動させる動作が生じるが,このような部材の移動や回動動作に人の手が巻き込まれたり,挟まれたりする可能性があるが,上記のように保護カバー21がその湾曲した内部空間に上記カム板5,その回動中心の脚支持軸7更にはストッパ15を包含しているので,これらの部材が外部に露出することがなく,人の手がその部分に近づくことが出来ないので,人手がこのような可動部分に巻き込まれたり,挟まれたりする危険性が完全に回避される。
また,前記レバー25の操作端部25aは,図1に示すように,2枚の脚支持台9,9に当たらないように,2枚の脚支持台9,9の間に設けられ,2枚の脚支持台9,9の間に収納されるような位置にあることが望ましい。 In such a leg support structure X, as theleg 1 is folded, an operation of rotating the stopper 15 by the lever 25 and an operation of rotating the cam plate 5 occur. There is a possibility that a human hand may be caught or pinched in the turning operation. As described above, the protective cover 21 is placed in the curved internal space of the cam plate 5 and the leg support shaft 7 at the center of rotation. Further, since the stopper 15 is included, these members are not exposed to the outside, and the human hand cannot approach the part, so that the human hand is caught or pinched by such a movable part. The risk of being lost is completely avoided.
Further, as shown in FIG. 1, the operation end portion 25a of thelever 25 is provided between the two leg support bases 9 and 9 so as not to hit the two leg support bases 9 and 9. It is desirable to be in a position where it can be accommodated between the leg support bases 9, 9.
また,前記レバー25の操作端部25aは,図1に示すように,2枚の脚支持台9,9に当たらないように,2枚の脚支持台9,9の間に設けられ,2枚の脚支持台9,9の間に収納されるような位置にあることが望ましい。 In such a leg support structure X, as the
Further, as shown in FIG. 1, the operation end portion 25a of the
上の例では,ストッパ支持軸11は,上記保護カバー21の内部に包含されていない。これは,ストッパ支持軸11の場合,単に軸周りに回動するだけであり,且つレバー25の回動動作範囲も狭いので,その回動による危険性が極めて少ないことによる。ただし,更に十分な安全性を考慮するならば,図6に示すように,ストッパ支持軸11も上記保護カバー21の湾曲する内部空間に包含するようにしても良い。
上記脚支持台9は,それぞれ独立に上記テーブル下面に固定されてなる2枚の板状の脚支持台9,9によって構成されている。
この点,例えば,特許文献2に開示された脚支持構造において用いられている脚支持台は,断面コ字状に形成されており,左右一体の板状部材によって構成されているが,このようなテーブル用脚を支持する支持台では,テーブルのサイズなどに応じて脚1のサイズが変化した場合,一対の脚支持台の間隔を変化させる必要があるために,上記一対の脚支持台が左右一体に構成された上記特許文献2に記載の脚支持構造では,多くのサイズの脚支持台が必要となり,これがコストを押し上げる原因の1つになっている。
また,このような断面コ字状で一体の脚支持台の場合,コ字状に曲げ加工を行った後に前記脚支持軸7等を取り付ける孔を加工する必要がある。しかし,コ字状になった脚支持台に精度よく加工することは至難の業であり,それによる加工コストの上昇という問題も指摘される。
これに対して,この実施形態に用いられた脚支持台9のように1対の脚支持台9,9がそれぞれ独立の場合には,その間の間隔を自由に調整できるので,脚やテーブルの寸法変更に柔軟に対応できる。また,左右の支持台9,9がそれぞれ独立しているので,それぞれ単独で穴あけ加工が可能で,前記脚支持軸7や,ストッパ支持軸11を支持する軸孔の加工精度が低下することがない。
また,この実施形態では,脚支持台9,9が左右に分離されている為,(脚支持台9,9をテーブル3に組付ける前は)保護カバー21を取付ける作業も容易であり,組付時間を短縮し,コストダウンを図ることができる。さらに脚支持台9,9が断面コ字状の場合は,保護カバー21を組付けるには,保護カバー21をコ字部分と脚支持軸等の隙間を通す必要がある。そのため組付け作業に熟練と時間を要すると共に,保護カバー21両端の形状も規制される。一方脚支持台9,9を左右に分割すると脚1の取付部付近をカバーする保護カバー両端部の形状も自由に設計することができる。例えば,保護カバー21の固定用端部21a(図2,図6の矢印Aの部分)を柔らかな平面とすることで,図2のように脚を折畳み,テーブルを積み重ねた時に天板面が傷つくことを防ぐクッション部材とすることが可能であり,部材の削減,コストダウンになる。
上の実施形態においては,当り部材が,カム板に取り付けられ,脚支持台側に上記当り部材が当接する第1及び第2の当り部が形成されているが,例えば,当り部材が,脚支持台に取付けられ,カム板側に上記当り部材が当接する第1及び第2の当り部が形成されていてもよい。
この場合,前記カム板側に,上記当り部材が上記脚のテーブル下面に立てた状態とテーブル下面に沿った折り畳み状態とにおいて,上記当り部材が当接する第1の当り部と第2の当り部とが形成されることになり,且つ,上記脚支持台側に,上記脚のテーブル下面に立てた状態とテーブル下面に沿った折り畳み状態とにおいて,上記ストッパが当接する第1のカム面と第2のカム面とが形成されることになる。その結果,上記脚がテーブル下面に立てた状態となった時に上記当り部材が上記第1の当り部に当接し且つストッパが第1のカム面に当接することで脚がテーブル下面に立てた状態で固定され,且つ,上記脚がテーブル下面に沿った折り畳み状態となった時に上記当り部材が上記第2の当り部に当接し且つストッパが第2のカム面に当接することで脚がテーブル下面に沿った折り畳み状態で固定されることになる。 In the above example, thestopper support shaft 11 is not included in the protective cover 21. This is because, in the case of the stopper support shaft 11, it merely rotates around the axis, and the rotation operation range of the lever 25 is narrow, so that the danger due to the rotation is very small. However, if sufficient safety is taken into consideration, the stopper support shaft 11 may also be included in the curved inner space of the protective cover 21, as shown in FIG.
Theleg support 9 is composed of two plate-like leg supports 9, 9 that are independently fixed to the lower surface of the table.
In this regard, for example, the leg support base used in the leg support structure disclosed inPatent Document 2 is formed in a U-shaped cross section and is constituted by a plate member integrally formed on the left and right sides. In the support table that supports the table legs, when the size of the leg 1 changes according to the size of the table, the distance between the pair of leg support tables needs to be changed. In the leg support structure described in Patent Document 2 that is integrally formed on the left and right, a large number of leg support bases are required, which is one of the causes for increasing the cost.
Further, in the case of such an integral leg support base having a U-shaped cross section, it is necessary to process a hole for mounting theleg support shaft 7 and the like after bending into a U-shape. However, it is extremely difficult to process the U-shaped leg support with high accuracy, and the problem of increased processing costs is also pointed out.
On the other hand, when the pair of leg support bases 9 and 9 are independent from each other like the leg support base 9 used in this embodiment, the distance between them can be freely adjusted. Can flexibly respond to dimensional changes. Further, since the left and right support bases 9 and 9 are independent from each other, drilling can be performed independently, and the processing accuracy of the shaft hole for supporting the leg support shaft 7 and the stopper support shaft 11 is lowered. Absent.
Further, in this embodiment, since the leg support bases 9 and 9 are separated on the left and right, the work of attaching the protective cover 21 is easy (before the leg support bases 9 and 9 are assembled to the table 3). The time required can be shortened and costs can be reduced. Further, when the leg support bases 9, 9 have a U-shaped cross section, in order to assemble the protective cover 21, it is necessary to pass the protective cover 21 through a gap between the U-shaped portion and the leg support shaft. For this reason, skill and time are required for the assembling work, and the shapes of both ends of the protective cover 21 are also restricted. On the other hand, if the leg support bases 9 and 9 are divided into left and right, the shape of both ends of the protective cover that covers the vicinity of the mounting portion of the leg 1 can be freely designed. For example, by making the fixing end 21a of the protective cover 21 (the portion indicated by the arrow A in FIGS. 2 and 6) a soft flat surface, the top plate surface is folded when the legs are folded and the tables are stacked as shown in FIG. It is possible to use a cushion member that prevents damage, reducing the number of members and reducing the cost.
In the above embodiment, the contact member is attached to the cam plate, and the first and second contact portions with which the contact member abuts are formed on the leg support base side. First and second contact portions that are attached to the support base and that contact the contact members may be formed on the cam plate side.
In this case, on the cam plate side, the first contact portion and the second contact portion with which the contact member abuts in the state where the contact member stands on the table lower surface of the leg and the folded state along the table lower surface. And the first cam surface and the first cam surface with which the stopper abuts on the leg support base side in a state where the leg is stood on the lower surface of the table and a folded state along the lower surface of the table. 2 cam surfaces are formed. As a result, when the leg is standing on the lower surface of the table, the contact member is in contact with the first contact portion and the stopper is in contact with the first cam surface, so that the leg is standing on the lower surface of the table. When the leg is folded along the lower surface of the table, the contact member comes into contact with the second contact portion and the stopper comes into contact with the second cam surface. It will be fixed in the folded state along.
上記脚支持台9は,それぞれ独立に上記テーブル下面に固定されてなる2枚の板状の脚支持台9,9によって構成されている。
この点,例えば,特許文献2に開示された脚支持構造において用いられている脚支持台は,断面コ字状に形成されており,左右一体の板状部材によって構成されているが,このようなテーブル用脚を支持する支持台では,テーブルのサイズなどに応じて脚1のサイズが変化した場合,一対の脚支持台の間隔を変化させる必要があるために,上記一対の脚支持台が左右一体に構成された上記特許文献2に記載の脚支持構造では,多くのサイズの脚支持台が必要となり,これがコストを押し上げる原因の1つになっている。
また,このような断面コ字状で一体の脚支持台の場合,コ字状に曲げ加工を行った後に前記脚支持軸7等を取り付ける孔を加工する必要がある。しかし,コ字状になった脚支持台に精度よく加工することは至難の業であり,それによる加工コストの上昇という問題も指摘される。
これに対して,この実施形態に用いられた脚支持台9のように1対の脚支持台9,9がそれぞれ独立の場合には,その間の間隔を自由に調整できるので,脚やテーブルの寸法変更に柔軟に対応できる。また,左右の支持台9,9がそれぞれ独立しているので,それぞれ単独で穴あけ加工が可能で,前記脚支持軸7や,ストッパ支持軸11を支持する軸孔の加工精度が低下することがない。

上の実施形態においては,当り部材が,カム板に取り付けられ,脚支持台側に上記当り部材が当接する第1及び第2の当り部が形成されているが,例えば,当り部材が,脚支持台に取付けられ,カム板側に上記当り部材が当接する第1及び第2の当り部が形成されていてもよい。
この場合,前記カム板側に,上記当り部材が上記脚のテーブル下面に立てた状態とテーブル下面に沿った折り畳み状態とにおいて,上記当り部材が当接する第1の当り部と第2の当り部とが形成されることになり,且つ,上記脚支持台側に,上記脚のテーブル下面に立てた状態とテーブル下面に沿った折り畳み状態とにおいて,上記ストッパが当接する第1のカム面と第2のカム面とが形成されることになる。その結果,上記脚がテーブル下面に立てた状態となった時に上記当り部材が上記第1の当り部に当接し且つストッパが第1のカム面に当接することで脚がテーブル下面に立てた状態で固定され,且つ,上記脚がテーブル下面に沿った折り畳み状態となった時に上記当り部材が上記第2の当り部に当接し且つストッパが第2のカム面に当接することで脚がテーブル下面に沿った折り畳み状態で固定されることになる。 In the above example, the
