Description

本発明は、家具の脚の底面に取り付けられる家具用脚受具に関する。   The present invention relates to a furniture leg holder attached to the bottom surface of a furniture leg.

従来、椅子や机等の家具を移動させる際に、家具の脚によって床面が擦れることにより、床面に傷がついたり騒音が発生することを防止するため、また、床面上での家具の滑りをよくするために、家具の脚の底面に家具用脚受具を取り付けることが行われている。   Conventionally, when moving furniture such as chairs and desks, the floor surface is rubbed by the legs of the furniture to prevent the floor surface from being scratched or generating noise. In order to improve the sliding of the furniture, a furniture leg holder is attached to the bottom surface of the furniture leg.

このような家具用脚受具の従来例として、特許文献１に記載された家具類に用いる受台がある。この受台は家具の脚の底面に打ち込み止着されるもので、家具の脚の底面に打ち込むための金属製の打込脚部と、この打込脚部の底部に固着されて床面に接するフッ素樹脂やフェルト製の受座部と、これら打込脚部と受座部とを完全一体化結合する樹脂製の中座部とから構成されている。   As a conventional example of such a leg holder for furniture, there is a cradle used for furniture described in Patent Document 1. This pedestal is driven and fixed to the bottom of the furniture leg, and is fixed to the floor with a metal driving leg for driving into the bottom of the furniture leg and the bottom of the driving leg. The contact portion is made of a fluororesin or felt that comes into contact, and a resin center portion that completely couples the driving leg portion and the receiving portion together.

特開昭８−１１２１５２号公報JP-A-8-112152

特許文献１に記載の家具類に用いる受台は家具の脚の底面に取り付ける際に、受座部の底面（床面に接する面）を金槌等で叩いて打込脚部を家具の脚の底面に打ち込む必要がある。しかし、受座部は外部から加えられる力に対して弾性変形能を有しており、受座部の底面を金槌で叩いたときに緩衝材として働いてしまうため、打込脚部の家具の脚の底面への打ち込み、すなわち、受台の家具の脚の底面への取り付けが困難になるという問題があった。   When the cradle used for the furniture described in Patent Document 1 is attached to the bottom surface of the furniture leg, the bottom surface of the seat portion (the surface in contact with the floor surface) is struck with a hammer or the like to place the driving leg portion of the furniture leg. Must be driven into the bottom. However, since the seat has elastic deformation with respect to the force applied from the outside, and acts as a cushioning material when the bottom surface of the seat is struck with a hammer, There has been a problem that it is difficult to drive the leg to the bottom, that is, to attach the cradle to the bottom of the leg of the furniture.

また、受座部は受台の長期間の使用により摩耗するので、受台を交換したいという要請がある。しかし、一体型で打ち込み式の受台を一旦家具の脚の底面に打ち込むと、脚の底面には孔が形成されてしまうため、別の受台を同じ孔に打ち込んでもその受台が脚の底面に強固には固定されないという問題があった。   Also, since the seat is worn by long-term use of the cradle, there is a request to replace the cradle. However, once the integrated and pedestal type pedestal is driven into the bottom of the leg of the furniture, a hole is formed in the bottom of the leg, so even if another pedestal is driven into the same hole, There was a problem that it was not firmly fixed to the bottom.

そこで、本発明の目的は、家具の脚の底面への取り付けを容易にすると共に、長期間に亘って使用可能な家具用脚受具を提供することにある。   Therefore, an object of the present invention is to provide a furniture leg holder that can be easily attached to the bottom surface of a furniture leg and can be used for a long period of time.

According to this furniture leg holder, first, the male screw member is fixed to the bottom surface of the furniture leg with a wood screw or a tapping screw, and then the female screw member is screwed to the male screw member and attached detachably. Since it can be assembled and attached to the bottom surface of the furniture leg, it can be easily attached to the bottom surface of the furniture leg as compared to a conventional integrated and driven-in furniture leg holder.
Further, according to this furniture leg holder, since the female screw member can be replaced while the male screw member is fixed to the bottom surface of the furniture leg, compared to the conventional integrated and driven-in furniture leg holder. It can be used for a long time. Here, the strength with respect to the load applied when using the male screw member and the female screw member is higher in the structure of the male screw member having the shaft portion than the female screw member having the recess, and is less likely to be damaged. The male screw member can be used for a longer period of time than the female screw member is fixed to the bottom surface of the furniture leg.

本発明によれば、外面に雄ねじが切られた軸部を備えた雄ねじ部材と、家具の脚の底面にねじ込むことによって前記軸部が前記家具の脚の底面に対して直角で下向きに突出した状態で前記雄ねじ部材を前記家具の脚の底面に固着する木ねじ又はタッピングねじと、前記雄ねじに螺合する雌ねじが内面に切られた上部開放の凹部を備え、前記雄ねじ部材に着脱自在に取り付けられて床面に接する雌ねじ部材とを有するので、家具の脚の底面への取り付けを容易にすると共に、長期間に亘って使用可能な家具用脚受具を提供することができる。   According to the present invention, a male screw member having a shaft portion with a male screw cut on the outer surface, and the shaft portion protrudes downward at a right angle to the bottom surface of the furniture leg by screwing into the bottom surface of the furniture leg.

次に、本実施例の家具用脚受具の家具の脚１の底面１ａへの取り付けについて説明する。   Next, attachment of the furniture leg holder of the present embodiment to the bottom surface 1a of the furniture leg 1 will be described.

先ず、雄ねじ部材１０の座部１５の上面を家具の脚１の底面１ａに対向させた状態で、雄ねじ部材１０の軸部１２の端面を金槌等で叩いて各針１６を家具の脚１の底面１ａに打ち込むことにより、雄ねじ部材１０を家具の脚１の底面１ａの中央部に仮止め状態で取り付ける。この際、雄ねじ部材１０は雌ねじ部材３０に比べて機械的強度が高く、軸部１２を叩くので、また、各針１６は軸部１２を軽く叩くだけで家具の脚１の底面１ａに打ち込むことができるので、樹脂製の雄ねじ部材１０が破損するのを防止しながら、雄ねじ部材１０を脚１の底面１ａに仮止め状態で容易に取り付けることができる。   First, in the state where the upper surface of the seat portion 15 of the male screw member 10 is opposed to the bottom surface 1a of the leg 1 of the furniture, the end surface of the shaft portion 12 of the male screw member 10 is hit with a hammer or the like, and each needle 16 is moved to the furniture leg 1. By driving into the bottom surface 1a, the male screw member 10 is attached to the central portion of the bottom surface 1a of the furniture leg 1 in a temporarily fixed state. At this time, the male screw member 10 has higher mechanical strength than the female screw member 30 and strikes the shaft portion 12, and each needle 16 is driven into the bottom surface 1a of the furniture leg 1 only by tapping the shaft portion 12. Therefore, the male screw member 10 can be easily attached to the bottom surface 1a of the leg 1 in a temporarily fixed state while preventing the resin male screw member 10 from being damaged.

次に、脚１の底面１ａに仮止め状態で取り付けた雄ねじ部材１０の中心部にある穴１３，１４を通して脚１の底面１ａに、木ねじ２０をねじ込むための下穴（木ねじ２０の軸部２１の直径の７０％くらいの大きさの穴）を開ける。この下穴を開けるために本実施例の家具用脚受具には、先端部がドリル形状の図示しないタッピングねじ（スクリューねじ）が付属されている。このタッピングねじをドライバーで脚１の底面１ａに仮止め状態で取り付けられた雄ねじ部材１０の中心部にある穴１３，１４を通して脚１の底面１ａにねじ込んだ後、取り外すことにより、脚１の底面１ａに仮止め状態で取り付けた雄ねじ部材１０の中心部にある穴１３，１４を通して脚１の底面１ａに下穴を開けることができる。この際、下穴を脚１の底面１ａの中心部に正確に開けることが非常に重要であるが、脚１の底面１ａに仮止め状態で取り付けた雄ねじ部材１０の中心部にある穴１３，１４を通して脚１の底面１ａに下穴を開けるので、下穴を脚１の底面１ａの中心部に正確に開けることができる。   Next, a pilot hole (shaft portion 21 of the wood screw 20) for screwing the wood screw 20 into the bottom surface 1a of the leg 1 through the holes 13 and 14 in the center portion of the male screw member 10 attached to the bottom surface 1a of the leg 1 in a temporarily fixed state. A hole with a size of about 70% of the diameter). In order to open the pilot hole, the furniture leg holder of the present embodiment is attached with a tapping screw (screw screw) (not shown) having a drilled tip. The tapping screw is screwed into the bottom surface 1a of the leg 1 through the holes 13 and 14 in the center of the male screw member 10 which is temporarily attached to the bottom surface 1a of the leg 1 with a screwdriver, and then removed to remove the bottom surface of the leg 1 A pilot hole can be made in the bottom surface 1a of the leg 1 through the holes 13 and 14 in the center portion of the male screw member 10 attached to 1a in a temporarily fixed state. At this time, it is very important to accurately open the pilot hole in the center portion of the bottom surface 1a of the leg 1, but the hole 13 in the center portion of the male screw member 10 attached to the bottom surface 1a of the leg 1 in a temporarily fixed state, 14, a pilot hole is made in the bottom surface 1 a of the leg 1, so that the pilot hole can be accurately made in the center of the bottom surface 1 a of the leg 1.

次に、脚１の底面１ａに開けた下穴に木ねじ２０をドライバーで脚１の底面１ａに仮止め状態で取り付けた雄ねじ部材１０の中心部にある穴１３，１４を通してねじ込み、木ねじ２０の頭部２２を雄ねじ部材１０の中心部にある穴１４に完全に埋め込むことにより、図２に示すように、座部１５の上面が家具の脚１の底面１ａに当接し、軸部１２が家具の脚１の底面１ａに対して直角で下向きに突出した状態で雄ねじ部材１０を家具の脚１の底面１ａに固着する。この際、雄ねじ部材１０は、脚１の底面１ａに打ち込まれている各針１６によって、木ねじ２０の軸部２１を中心に回転するのを阻止した状態で家具の脚１の底面１ａに固着されている。   Next, the wood screw 20 is screwed into the prepared hole formed in the bottom surface 1a of the leg 1 with a screwdriver through the holes 13 and 14 in the center of the male screw member 10 attached to the bottom surface 1a of the leg 1 in a temporarily fixed state. By completely embedding the portion 22 in the hole 14 in the center portion of the male screw member 10, as shown in FIG. 2, the upper surface of the seat portion 15 comes into contact with the bottom surface 1a of the leg 1 of the furniture, and the shaft portion 12 is made of the furniture. The male screw member 10 is fixed to the bottom surface 1a of the furniture leg 1 in a state of projecting downward at a right angle to the bottom surface 1a of the leg 1. At this time, the male screw member 10 is fixed to the bottom surface 1a of the leg 1 of the furniture in a state in which it is prevented from rotating around the shaft portion 21 of the wood screw 20 by each needle 16 driven into the bottom surface 1a of the leg 1. ing.

次に、木ねじ２０によって家具の脚１の底面１ａに固着された雄ねじ部材１０の座部１５の下面及び軸部１２の端面に雌ねじ部材３０の上面の収容凹部３３を対向させた状態で、雌ねじ部材３０を手で回しながら雄ねじ部材１０の雄ねじ１１と雌ねじ部材３０の雌ねじを螺合させて雌ねじ部材３０の収容凹部３３に雄ねじ部材１０をねじ込んで行き、図２に示すように、雄ねじ部材１０を雌ねじ部材３０の収容凹部３３に完全に埋め込んで収容することにより、雄ねじ部材１０に対して雌ねじ部材３０を、雄ねじ部材１０の軸部１２の端面と雌ねじ部材３０の凹部３２の底面とが密着し、かつ、雄ねじ部材１０の座部１５の下面と雌ねじ部材３０の上部凹部３４（収容凹部３３内の段面）の底面とが密着し、かつ、雌ねじ部材３０の収容凹部３３の周囲に残された円形リング状の上面と家具の脚１の底面１ａとが密着した状態で螺合して着脱自在に取り付ける。これにより、本実施例の家具用脚受具は家具の脚１の底面１ａに組み立てて取り付けることができる。   Next, in the state where the housing recess 33 on the upper surface of the female screw member 30 is opposed to the lower surface of the seat portion 15 and the end surface of the shaft portion 12 of the male screw member 10 fixed to the bottom surface 1 a of the leg 1 of the furniture by the wood screw 20. While the member 30 is turned by hand, the male screw 11 of the male screw member 10 and the female screw of the female screw member 30 are screwed together, and the male screw member 10 is screwed into the housing recess 33 of the female screw member 30, and as shown in FIG. Is completely embedded in the receiving recess 33 of the female screw member 30, and the female screw member 30 is brought into close contact with the male screw member 10 so that the end surface of the shaft portion 12 of the male screw member 10 and the bottom surface of the concave portion 32 of the female screw member 30 are in close contact with each other. In addition, the lower surface of the seat portion 15 of the male screw member 10 and the bottom surface of the upper concave portion 34 (step surface in the accommodating concave portion 33) of the female screw member 30 are in close contact with each other, and the concave portion of the female screw member 30 is accommodated. Screwed in a state in which the remaining circular ring-shaped top and bottom surfaces 1a furniture leg 1 are in close contact around the 3 detachably attached. Thereby, the leg holder for furniture of a present Example can be assembled and attached to the bottom face 1a of the leg 1 of furniture.

以上のように、家具の脚１の底面１ａに取り付けた本実施例の家具用脚受具は、ＰＴＦＥ製の雌ねじ部材３０の下向きに凸状な球面に形成された底面を床面２に接触させて家具を床面２上で受け支えることにより、家具を移動させる際に、その家具の脚１によって床面２が擦れることにより、床面２に傷がついたり騒音が発生することを防止すると共に、床面２上での家具の滑り（移動）をよくすることができる。   As described above, the furniture leg holder of this embodiment attached to the bottom surface 1a of the furniture leg 1 contacts the floor surface 2 with the bottom surface formed in the downward convex spherical surface made of PTFE female screw member 30.

In addition, the sliding (moving) of the furniture on the floor surface 2 can be improved.

次に、本実施例の家具用脚受具の作用について説明する。   Next, the operation of the furniture leg holder of this embodiment will be described.

以上のように、本実施例の家具用脚受具は、外面に雄ねじ１１が切られた軸部１２を備えた雄ねじ部材１０と、家具の脚１の底面１ａにねじ込むことによって軸部１２が家具の脚１の底面１ａに対して直角で下向きに突出した状態で雄ねじ部材１０を家具の脚１の底面１ａに固着する木ねじ２０と、雄ねじ１１に螺合する雌ねじ３１が内面に切られた上部開放の凹部３２を備え、雄ねじ部材１０に着脱自在に取り付けられて床面２に接する雌ねじ部材３０とを有して構成されており、この本実施例の家具用脚受具によれば、先ず、木ねじ２０によって家具の脚１の底面１ａに雄ねじ部材１０を固着し、その後、雄ねじ部材１０に対して雌ねじ部材３０を螺合して着脱自在に取り付けることで、家具の脚１の底面１ａに組み立てて取り付けることができるので、従来の一体型で打ち込み式の家具用脚受具に比べて家具の脚１の底面１ａへの取り付けが容易になる。   As described above, the furniture leg holder according to the present embodiment has the male screw member 10 including the shaft portion 12 having the external thread 11 cut on the outer surface and the shaft portion 12 by being screwed into the bottom surface 1a of the leg 1 of the furniture. A wood screw 20 that fixes the male screw member 10 to the bottom surface 1a of the furniture leg 1 in a state of projecting downward at a right angle to the bottom surface 1a of the furniture leg 1 and a female screw 31 that engages with the male screw 11 are cut into the inner surface. According to the furniture leg holder of the present embodiment, it has a recess 32 that is open at the top, and has a female screw member 30 that is detachably attached to the male screw member 10 and is in contact with the floor surface 2. First, the male screw member 10 is fixed to the bottom surface 1a of the furniture leg 1 with the wood screw 20, and then the female screw member 30 is screwed onto the male screw member 10 so as to be detachably attached, whereby the bottom surface 1a of the furniture leg 1 is attached. Assemble and attach Since it is, attachment to the bottom surface 1a of the furniture leg 1 as compared with the conventional integral with implantation type furniture leg bracket as is facilitated.

また、本実施例の家具用脚受具によれば、雄ねじ部材１０を家具の脚１の底面１ａに固着したまま雌ねじ部材３０を交換することができるので、従来の一体型で打ち込み式の家具用脚受具に比べて長期間に亘って使用可能になる。ここで、雄ねじ部材１０と雌ねじ部材３０の使用時の荷重負荷に対する強度は、それぞれの構造上、凹部３２を備える雌ねじ部材３０よりも軸部１２を備える雄ねじ部材１０の方が高く破損し難いので、木ねじ２０によって家具の脚１の底面１ａに雌ねじ部材３０を固着するのに比べて雄ねじ部材１０を固着する方がより長期間に亘って使用可能になる。   Further, according to the furniture leg holder of the present embodiment, the female screw member 30 can be replaced while the male screw member 10 is fixed to the bottom surface 1a of the furniture leg 1, so that the conventional integrated and driven-in furniture is provided. It can be used for a long period of time compared to the leg holder for use. Here, the strength with respect to the load applied when the male screw member 10 and the female screw member 30 are used is higher in the structure of the male screw member 10 including the shaft portion 12 than the female screw member 30 including the recess 32, and is not easily damaged. The male screw member 10 can be used for a longer period of time than the female screw member 30 is fixed to the bottom surface 1a of the furniture leg 1 by the wood screw 20.

また、本実施例の家具用脚受具によれば、使用時に雄ねじ部材１０の軸部１２の端面と雌ねじ部材３０の凹部３２の底面とが密着しており、使用時の荷重負荷を雄ねじ部材１０では雄ねじ１１だけでなく軸部１２の端面でも受けることができるので、雄ねじ部材１０の雄ねじ１１が破損し難く、より長期間に亘って使用可能になる。   Moreover, according to the furniture leg holder of the present embodiment, the end surface of the shaft portion 12 of the male screw member 10 and the bottom surface of the concave portion 32 of the female screw member 30 are in close contact with each other, and the load load during use is reduced. 10 can be received not only by the male screw 11 but also by the end face of the shaft portion 12, so that the male screw 11 of the male screw member 10 is hardly damaged and can be used for a longer period of time.

また、本実施例の家具用脚受具によれば、家具の脚１の底面１ａへの取り付け時に雄ねじ部材１０が雌ねじ部材３０によって完全に包み込まれるので、雌ねじ部材３０を交換しながら長期間に亘って使用することで、その使用期間はきれいな外観を維持することができる。   Further, according to the furniture leg holder of the present embodiment, the male screw member 10 is completely encased by the female screw member 30 when the furniture leg 1 is attached to the bottom surface 1a. By using it for a long time, it is possible to maintain a clean appearance during the period of use.

次に、本発明の実施例２について説明する。図１，図２示した実施例１では、雌ねじ部材３０に雄ねじ部材１０の全体を回転自在に収容する上部開放の収容凹部３３を備えたが、雌ねじ部材３０に雄ねじ部材１０の軸部１２を収容する凹部３２のみを備え、家具の脚１の底面１ａへの取り付け時に雄ねじ部材１０の座部１５を雌ねじ部材３０の上面に重ね合わせる構造を有する家具用脚受具としてもよい（実施例２）。この実施例２の家具用脚受具においては、平面視における雄ねじ部材１０の座部１５の外形状と雌ねじ部材３０の外形状とを同形に設定しておくことで、家具の脚１の底面１ａへの取り付け時に雄ねじ部材１０の座部１５の外面のみが外観に現れるだけであるから、実施例１の家具用脚受具と同様に、雌ねじ部材３０を交換しながら長期間に亘って使用することで、その使用期間はきれいな外観を維持することができる。   Next, a second embodiment of the present invention will be described. In the first embodiment shown in FIGS. 1 and 2, the female screw member 30 is provided with the upper open accommodation recess 33 for rotatably accommodating the entire male screw member 10, but the female screw member 30 is provided with the shaft portion 12 of the male screw member 10. It is good also as a leg holder for furniture which has only the recessed part 32 to accommodate and has a structure which superimposes the seat part 15 of the external thread member 10 on the upper surface of the internal thread member 30 at the time of attachment to the bottom face 1a of the leg 1 of furniture (Example 2). ). In the furniture leg holder according to the second embodiment, the outer shape of the seat 15 of the male screw member 10 and the outer shape of the female screw member 30 in the plan view are set to be the same shape, so that the bottom surface of the leg 1 of the furniture is obtained. Since only the outer surface of the seat portion 15 of the male screw member 10 appears in appearance when attached to 1a, it is used over a long period of time while replacing the female screw member 30 as in the case of the furniture leg holder of the first embodiment. By doing so, a clean appearance can be maintained during the period of use.

また、実施例２の家具用脚受具においては、雄ねじ部材１０の座部１５の外形状及び雌ねじ部材３０の外形状として円形以外の長円形、正方形、長方形等を採用することができる。   In addition, in the furniture leg holder according to the second embodiment, an oval shape other than a circle, a square, a rectangle, or the like can be adopted as the outer shape of the seat portion 15 of the male screw member 10 and the outer shape of the female screw member 30.
