Description

本発明は、テーブルや椅子等の家具類の脚の下端部に嵌めて使用されるキャップ、即ち、家具脚用キャップに関するものである。   The present invention relates to a cap that is used by being fitted to a lower end portion of a leg of furniture such as a table or a chair, that is, a furniture leg cap.

椅子の脚や食卓用テーブルの脚といった家具類の脚の先端に被せて使用されるキャップが知られている。このキャップは、椅子等の引き摺りによって床や脚先に傷が付かないようにするためや、容易に移動しないように滑り止めするためにより、脚下端部に装着される。脚のある家具類としては、勉強机や会議用机といった机、ベッド等、種々のものが考えられる。   There are known caps that are used on the ends of furniture legs such as chair legs and table table legs. The cap is attached to the lower end of the leg so as not to damage the floor or the leg tip by dragging a chair or the like, or to prevent slipping so as not to move easily. As furniture with legs, various things such as a desk such as a study desk and a conference desk, a bed, and the like can be considered.

前記前者の従来例としては、特許文献１において開示される「家具用脚カバー」が知られている。この家具用脚カバーは、シリコンゴム等の超軟質性樹脂製で脚先に嵌る外挿部（１）と、その外挿部の底面に一体的に設けられるポリアミド等の硬質樹脂製の摺動底部（２）とから構成されている。   As the former conventional example, a “furniture leg cover” disclosed in Patent Document 1 is known. This furniture leg cover is made of an ultra-soft resin such as silicon rubber, and an extrapolated portion (1) that fits on the tip of the leg, and a sliding made of a hard resin such as polyamide provided integrally on the bottom surface of the extrapolated portion. It consists of a bottom (2).

前記後者の従来例としては、特許文献２において開示される「家具用脚体の滑り止め」が知られている。これは、ゴム材から成る袋体（Ａ）の底壁の中央部を下方突出させてその底面をフッ素樹脂等の底μ材で成る滑り面とし、底壁の外周部はゴム材のままで成る滑り止め面として構成してある。例えば、椅子単品の場合には、軽いので脚下端に装備されている袋体（Ａ）の下方突出する滑り面（４）が床に接しており、場所を変える等の移動がし易い状態になっている、そして、椅子に人体等が着座して重くなると滑り面（４）が弾性潰れ変形して滑り止め面（５）が床に強く接し、簡単には動かなくなって安定する、という２種類の機能を発揮できると記載されている。   As the latter conventional example, there is known “non-slip of furniture legs” disclosed in Patent Document 2. This is because the center part of the bottom wall of the bag body (A) made of rubber material protrudes downward and its bottom surface is made into a sliding surface made of a bottom μ material such as fluororesin, and the outer peripheral part of the bottom wall remains rubber material. It is configured as a non-slip surface. For example, in the case of a single chair, since it is light, the sliding surface (4) protruding downward of the bag (A) provided at the lower end of the leg is in contact with the floor, so that it can easily move such as changing the place. And when a human body or the like sits on a chair and becomes heavy, the sliding surface (4) is elastically deformed and the non-slip surface (5) comes into strong contact with the floor, and it cannot easily move and stabilize. It is described that it can perform various functions.

。 Embodiments of a leg cap for furniture according to the present invention will be described below with reference to the drawings.

〔実施例１〕
実施例１による家具用脚キャップ（以下、単に「脚キャップ」と略称する）Ｃは、図１，図４，図５に示すように、家具類の脚先端に嵌着可能な有底筒状でゴム（弾性材の一例）製のキャップ基体１と、キャップ基体１の下端側（先端側）に支持手段３を介して着脱可能に取付けられる硬質合成樹脂製の接地体２とを備えるとともに、軸心Ｐを有する平面視で円形のものに構成されている。 [Example 1]
The furniture leg cap (hereinafter simply referred to as “leg cap”) C according to the first embodiment is a bottomed cylindrical shape that can be fitted to the leg ends of furniture as shown in FIGS. And a cap base body 1 made of rubber (an example of an elastic material), and a hard synthetic resin grounding body 2 detachably attached to the lower end side (front end side) of the cap base body 1 via the support means 3, It is comprised by the circular thing by planar view which has the axial center P. FIG.

キャップ基体１は、図１〜図６に示すように、家具類の脚底を載せ付け可能な底壁４、底壁４の外周に続いて上方に立ち上がる上窄まり円筒状の側周壁５、及び底壁４から下方に突出するボス筒壁６を有する略回転体に形成されている。側周壁５は、上窄まり円筒状の下部筒部５Ａと、内周面及び外周面の双方が鋸刃状のギザギザ面に形成されて下部筒部５Ａの上端に続く縮径された上部筒部（開口部の一例）５Ｂとを有している。上部筒部５Ｂがギザギザ面であるから、家具の太い脚を入れる場合に大径に伸ばし易いとともに、脚の断面形状が丸でも四角でも歪な形状でも適合して強固に弾性挟持させることができる。   As shown in FIGS. 1 to 6, the cap base 1 includes a bottom wall 4 on which furniture bases can be placed, an upper cylindrical side peripheral wall 5 that rises upward following the outer periphery of the bottom wall 4, and It is formed in a substantially rotating body having a boss cylinder wall 6 protruding downward from the bottom wall 4. The side peripheral wall 5 has an upper constricted cylindrical lower cylindrical part 5A, and an inner cylinder whose outer peripheral surface and both outer peripheral surfaces are formed in a saw-toothed jagged surface and whose diameter is reduced following the upper end of the lower cylindrical part 5A. Part (an example of an opening part) 5B. Since the upper cylindrical portion 5B has a jagged surface, it can be easily extended to a large diameter when inserting a thick leg of furniture, and can be firmly elastically clamped in conformity with a round, square or distorted cross-sectional shape of the leg. .

底壁４は、四角平面が軸心Ｐ周りに４５度ずれて形成されたような平面視で星形（図３参照）を呈する下側の第１底面４Ａと、その第１底面４Ａを内側の打抜き孔として有するとともに側周壁５下端内側の円形外周を有する上側の第２底面４Ｂとを備える段差壁に形成されている。そして、底壁４の底面４ａには、後述する面ファスナ３の構成要素であるパイル状ファスナ部分３Ａが一体的に装備されている。   The bottom wall 4 has a lower first bottom surface 4A having a star shape (see FIG. 3) in a plan view in which a square plane is formed by being shifted by 45 degrees around the axis P, and the first bottom surface 4A is disposed on the inner side. Are formed in a stepped wall having an upper second bottom surface 4B having a circular outer periphery inside the lower end of the side peripheral wall 5. The bottom wall 4a of the bottom wall 4 is integrally provided with a pile-shaped fastener portion 3A that is a component of the surface fastener 3 described later.

接地体２は、ボス筒壁６に外嵌可能なカバー側壁７と、凸曲面状の底面８ａを持つ接地壁８とから成る略有底筒状の部材であり、接地壁８の上面は、一段下がった環状の載置面８ｂと、ボス筒壁６のリング底面６ａを受止める頂面８ｃとを備えている。載置面８ｂには、後述する面ファスナ３の構成要素である鉤状ファスナ部分３Ｂが一体的に装備されている。底面８ａは、もっと小なる曲率で湾曲する面や平らな面でも良い。   The grounding body 2 is a substantially bottomed cylindrical member comprising a cover side wall 7 that can be fitted onto the boss cylindrical wall 6 and a grounding wall 8 having a convex curved bottom surface 8a. An annular placement surface 8b lowered one step and a top surface 8c for receiving the ring bottom surface 6a of the boss cylinder wall 6 are provided. The mounting surface 8b is integrally equipped with a hook-shaped fastener portion 3B which is a component of the surface fastener 3 described later. The bottom surface 8a may be a curved surface or a flat surface with a smaller curvature.

支持手段３は、キャップ基体１の底面４ａに熱融着等によって一体化されるパイル状ファスナ部分３Ａと、接地体２の載置面８ｂに接着等によって一体化される鉤状ファスナ部分３Ｂとで成る面ファスナである。つまり、支持手段３が、キャップ基体１の底面４ａに沿う状態でキャップ基体１と接地体２とに跨って配備される面ファスナである。カバー側壁７をボス筒壁６に外嵌させて、頂面８ｃがリング底面６ａに当接するまで接地体２をキャップ基体１に嵌め込み装着すると、鉤状ファスナ部分３Ｂとパイル状ファスナ部分３Ａとが押付けられて面ファスナ３として機能する状態になるように設定されている。   The support means 3 includes a pile-shaped fastener portion 3A that is integrated with the bottom surface 4a of the cap base 1 by thermal fusion or the like, and a hook-shaped fastener portion 3B that is integrated with the mounting surface 8b of the grounding body 2 by adhesion or the like. It is an area fastener. That is, the support means 3 is a surface fastener that is disposed across the cap base 1 and the grounding body 2 in a state along the bottom surface 4 a of the cap base 1. When the cover side wall 7 is fitted onto the boss tube wall 6 and the grounding body 2 is fitted and mounted on the cap base 1 until the top surface 8c contacts the ring bottom surface 6a, the hook-shaped fastener portion 3B and the pile-shaped fastener portion 3A are formed. It is set so as to be pressed and to function as the surface fastener 3.

キャップ基体１は、家具類、例えば図７に示すように、椅子（図示省略）の脚１１の下端部を強制挿入して係止させるためのものである。図７に示す脚１１は、断面形状が正方形等の四角であって底部側壁４ｂに丁度内嵌して、脚底１１ａが第１底面４Ａに当接している。従って、上部筒部５Ｂは元の丸形状からその丸が内接する程度の四角形状に弾性拡径され、脚１１を強く締付けてしっかりと保持できるようになっている。尚、第１底面４Ａより大きな径の脚の場合には、上部筒部５Ｂがさらに弾性拡径されて強固に挟持するとともに、脚底を第２底面４Ｂに載せ付けて安定保持させることが可能である。   The cap base 1 is for forcibly inserting and locking furniture, for example, a lower end portion of a leg 11 of a chair (not shown) as shown in FIG. The leg 11 shown in FIG. 7 has a square shape such as a square, and is fitted into the bottom side wall 4b. The leg bottom 11a is in contact with the first bottom surface 4A. Accordingly, the upper cylindrical portion 5B is elastically expanded from the original round shape to a square shape in which the circle is inscribed so that the leg 11 can be firmly clamped and held firmly. In the case of a leg having a diameter larger than that of the first bottom surface 4A, the upper cylindrical portion 5B is further elastically expanded and firmly clamped, and the leg bottom can be placed on the second bottom surface 4B and stably held. is there.

さて、家具類の脚下端に装着される脚キャップＣは、窄められている上部筒部５Ｂの弾性嵌合によってしっかりと装着保持されており、その下部には低摩擦係数の硬質合成樹脂製接地体２が装備されているので滑りが良く、椅子を引き摺っても床に傷が付き難いとともに軽快に椅子を引き摺り移動することができる。面ファスナ３はせん断方向には引き剥がしに対して強い耐力があるものであるから、引き摺り等によってキャップ基体１と接地体２とを互いに横方向に引き離そうとする強い力が作用しても、接地体２がキャップ基体１から外れることはまず生じない。   Now, the leg cap C to be attached to the lower leg of the furniture is firmly attached and held by the elastic fitting of the narrowed upper cylindrical part 5B, and the lower part is made of a hard synthetic resin having a low friction coefficient. Since the grounding body 2 is equipped, the sliding is good, and even if the chair is dragged, the floor is hardly damaged and the chair can be dragged and moved easily. Since the surface fastener 3 has a strong resistance to peeling in the shearing direction, even if a strong force is applied to pull the cap base 1 and the grounding body 2 apart from each other by dragging or the like, the grounding It is unlikely that the body 2 is detached from the cap base 1.

そして、カバー側壁７とボス筒壁６とにより、キャップ基体１と接地体２とが、キャップ基体１の底面４ａに交差する方向（実施例１では直交）にて嵌り合う凹凸嵌合部９を有している。凹凸嵌合部９は、キャップ基体１と接地体２とを着脱可能に連結させる支持手段３の補助的な機能を有して、接地体２がキャップ基体１から外れ難くするとともに、すっきりとした外観として見栄の向上にも寄与している。   Then, by the cover side wall 7 and the boss cylinder wall 6, the concave / convex fitting portion 9 in which the cap base 1 and the grounding body 2 are fitted in the direction intersecting the bottom surface 4 a of the cap base 1 (orthogonal in the first embodiment). Have. The concave / convex fitting portion 9 has an auxiliary function of the support means 3 for detachably connecting the cap base 1 and the grounding body 2, making it difficult for the grounding body 2 to be detached from the cap base 1 and clean. It also contributes to improving the appearance as an appearance.

接地体２がキャップ基体１に対して着脱可能であるから、例えば、ゴム等の摩擦係数の高い材料で形成され、かつ、鉤状ファスナ部分３Ｂが一体的に装備される接地体２に交換すれば、滑らせ仕様の脚キャップから滑り止め仕様の脚キャップに切り換えることができる。この場合、キャップ基体は共通であって接地体２のみ付け換えできるようになっているから、構造簡単で簡単便利に、しかも椅子等の家具の重さには無関係に滑らせ仕様と滑り止め仕様との変更が行えるという良さがある。   Since the grounding body 2 can be attached to and detached from the cap base body 1, the grounding body 2 is replaced with a grounding body 2 that is formed of a material having a high coefficient of friction such as rubber and that is integrally equipped with the hook-shaped fastener portion 3B. Thus, it is possible to switch from a slip-capable leg cap to a non-slip-cap leg cap. In this case, since the cap base is the same and only the grounding body 2 can be replaced, the structure is simple, simple and convenient, and the sliding and anti-slip specifications are independent of the weight of furniture such as chairs. It is good that it can be changed.

また、図２等示すように、上部筒部５Ｂは外面１２及び内面１３共にギザギザ面であり、かつ、外面１２の径外側に突出する凸ギザ１２ａと内面１３の径外側に凹入する凹ギザ１３ａとが軸心Ｐに関する互いに同一な放射線上に位置するように構成されている。これにより、上部筒部５Ｂは一種の折り畳まれた襞のような壁になっており、材質がゴムであることによる伸びに加えて、構造上の伸び易さも加わり、かなりの範囲の脚１１の径にも対応して挿入でき、かつ、しっかりと弾性挟持できるものとなっている。   Further, as shown in FIG. 2 and the like, the upper cylindrical portion 5B has a jagged surface on both the outer surface 12 and the inner surface 13, and a convex jagged surface 12a that protrudes on the outer side of the outer surface 12 and a concave surface that is recessed on the outer side of the inner surface 13. 13a is located on the same radiation with respect to the axis P. As a result, the upper cylindrical portion 5B is a kind of a folded fold-like wall. In addition to the elongation due to the material being rubber, the structure is easily extended, and the leg 11 in a considerable range can be obtained. It can be inserted corresponding to the diameter and can be firmly elastically clamped.

〔実施例２〕
接地体２としては、図８に示すように、接地壁８の底面にフェルトｆを一体的に設けた滑らせ仕様のものも可能である。例えば、平面状の底面８ａの中央部を凹ませて段差の付いた取付用面１０を形成し、その取付用面１０にフェルトｆを一体的に設ける構成が考えられる。つまり、フェルト付接地体２を有する脚キャップＣである。 [Example 2]
As shown in FIG. 8, the grounding body 2 may be of a sliding specification in which a felt f is integrally provided on the bottom surface of the grounding wall 8. For example, a configuration may be considered in which the mounting surface 10 having a step is formed by denting the central portion of the flat bottom surface 8a, and the felt f is integrally provided on the mounting surface 10. That is, it is the leg cap C which has the grounding body 2 with felt.

〔別実施例〕
支持手段３としては、例えばカバー側壁７とボス筒壁６とを螺合させるといった具合に、螺着させる構成も可能である。また、凹凸嵌合部９が無く、支持手段３のみ備える脚キャップＣでも良い。面ファスナ３は、キャップ基体１に鉤状ファスナ部分３Ｂが固定され、かつ、接地体２にパイル状ファスナ部分３Ａが固定される構造でも良い。 [Another Example]
The support means 3 may be configured to be screwed, for example, such that the cover side wall 7 and the boss cylinder wall 6 are screwed together. Moreover, the leg cap C which does not have the uneven | corrugated fitting part 9 and is provided only with the support means 3 may be sufficient. The hook-and-loop fastener 3 may have a structure in which the hook-shaped fastener portion 3B is fixed to the cap base 1 and the pile-shaped fastener portion 3A is fixed to the grounding body 2.
