Description

本発明は、吊り戸の下部振止装置の床面設置部材に関するものである。 The present invention relates to a floor surface installation member of a lower vibration damping device for a hanging door.

従来、天井レールにランナーを介して走行自在に吊り下げられた吊り戸に対し、床面に設置したケースに磁力によって突出可能に設けられたガイドピンが、吊り戸本体の下面に形成された案内溝に挿入されることにより、吊り戸のガイドを行う吊り戸の下部振止装置が知られている（特許文献１参照。）。 Conventionally, a guide pin is provided on the lower surface of the hanging door body so that it can be projected by magnetic force in a case installed on the floor, as opposed to a hanging door that is hung freely on a ceiling rail via a runner. A lower vibration damping device for a hanging door that guides the hanging door by being inserted into a groove is known (see Patent Document 1).

ところで、特許文献１に開示された吊り戸の下部振止装置においては、ガイドピンが単一の部材からなるため、ガイドピンの突出長さを確保しようとすると、ガイドピン及びケースを含む床面設置部材の高さ方向の寸法が大きくなり、直貼りフロアのように十分な没入深さを確保しにくい構造の場合、吊り戸の下部振止装置を適用できないという問題があった。 By the way, in the lower vibration device for a hanging door disclosed in Patent Document 1, since the guide pin is composed of a single member, when trying to secure the protruding length of the guide pin, the floor surface including the guide pin and the case In the case of a structure such as a directly attached floor where it is difficult to secure a sufficient immersion depth due to the large dimension of the installation member in the height direction, there is a problem that the lower vibration device of the hanging door cannot be applied.

一方、この問題に対処するために、ガイドピンを、磁石を先端に設けた第１部材と、この第１部材が上方に突出自在に嵌め込まれた筒状をした第２部材とで構成するようにしたテレスコピック構造のものが提案され、実用化されている（特許文献２〜３参照。）。 On the other hand, in order to deal with this problem, the guide pin is composed of a first member provided with a magnet at the tip and a tubular second member in which the first member is fitted so as to project upward. A telescopic structure has been proposed and put into practical use (see Patent Documents 2 and 3).

ところで、特許文献２〜３に開示された吊り戸の下部振止装置においては、ガイドピンの突出長さを確保しながら、ガイドピン及びケースを含む床面設置部材の高さ方向の寸法を小さく抑えることができ、直貼りフロアのように十分な没入深さを確保しにくい構造の場合でも、吊り戸の下部振止装置を適用できるという利点を有する反面、ガイドピンを円滑に昇降させるために、ケースと第２部材及び第１部材と第２部材との間、すなわち、ケースの内周面と第２部材の外周面及び第１部材の内周面と第２部材の外周面との間には、それぞれクリアランスが設けられており、このため、上昇した第１部材には、最大で前記２つのクリアランスを合算したぶれが生じ、このぶれが吊り戸本体の幅方向に生じると、ガイドピンが吊り戸本体の案内溝内に正確に挿入されなくなるという問題があった。 By the way, in the lower anti-vibration device of the hanging door disclosed in Patent Documents 2 to 3, the dimension in the height direction of the floor surface installation member including the guide pin and the case is reduced while ensuring the protruding length of the guide pin. Even in the case of a structure that can be suppressed and it is difficult to secure a sufficient immersion depth such as a directly attached floor, it has the advantage that the lower anti-vibration device of the hanging door can be applied, but on the other hand, to smoothly raise and lower the guide pin. In addition, between the case and the second member and between the first member and the second member, that is, the inner peripheral surface of the case and the outer peripheral surface of the second member, the inner peripheral surface of the first member and the outer peripheral surface of the second member. Clearances are provided between them, and for this reason, the raised first member causes a shake that is the sum of the two clearances at the maximum, and when this shake occurs in the width direction of the hanging door body, a guide is provided. There is a problem that the pin cannot be accurately inserted into the guide groove of the hanging door body.

本発明は、特許文献２〜３に開示された吊り戸の下部振止装置が有する、ガイドピンの突出長さを確保しながら、ガイドピン及びケースを含む床面設置部材の高さ方向の寸法を小さく抑えることができるという利点を享有しながら、上昇時の第１部材の吊り戸本体の幅方向の寸法精度を高めることで、ガイドピンを吊り戸本体の案内溝内に正確に挿入されるようにすることができる吊り戸の下部振止装置の床面設置部材を提供することを目的とする。 INDUSTRIAL APPLICABILITY The present invention has dimensions in the height direction of a floor installation member including a guide pin and a case, while ensuring the protruding length of the guide pin, which is possessed by the lower anti-vibration device of the hanging door disclosed in Patent Documents 2 and 3. The guide pin is accurately inserted into the guide groove of the hanging door body by improving the dimensional accuracy in the width direction of the hanging door body of the first member when ascending, while enjoying the advantage of being able to keep the size small. It is an object of the present invention to provide a floor surface mounting member for a lower vibration device for a hanging door.

上記目的を達成するため、本発明の吊り戸の下部振止装置の床面設置部材は、床面に設置されるケースに、吊り戸本体の案内溝に配設した磁石又は磁性体に吸引される磁石を配設したガイドピンを上方に突出可能に収納した吊り戸の下部振止装置の床面設置部材において、前記ガイドピンを、上端部に磁石を設け、下方に開口する空間を形成した第１部材と、該第１部材の下方に開口する空間内に嵌入可能に形成した第２部材とで構成し、収納状態で、第１部材がケース内に没入するとともに、第２部材が第１部材の下方に開口する空間内に嵌入した状態となり、この状態から、第１部材が磁力によって吸引されてケース内から上昇する際に、第１部材に従動して第２部材が上昇するようにしたことを特徴とする。 In order to achieve the above object, the floor installation member of the lower vibration device of the hanging door of the present invention is attracted to the case installed on the floor by a magnet or a magnetic material arranged in the guide groove of the hanging door main body. In the floor installation member of the lower anti-vibration device of the hanging door in which the guide pin on which the magnet is arranged is housed so as to be projectable upward, the guide pin is provided with a magnet at the upper end to form a space for opening downward. It is composed of a first member and a second member formed so as to be fitted in a space opened below the first member. In the stored state, the first member is immersed in the case and the second member is the second member. It is in a state of being fitted in a space that opens below the first member, and from this state, when the first member is attracted by a magnetic force and rises from the inside of the case, the second member moves up according to the first member. It is characterized by having made it.

この場合において、前記第１部材に設けた磁石の外周面が、第１部材の外周面を構成するようにすることができる。 In this case, the outer peripheral surface of the magnet provided on the first member can form the outer peripheral surface of the first member.

また、前記第１部材に従動して第２部材が上昇する際に、ケースの内周面にガイドされて上昇するようにすることができる。 Further, when the second member rises in accordance with the first member, it can be guided by the inner peripheral surface of the case to rise.

また、前記第１部材の上部部材の軸部が、第２部材を貫通、摺動するようにすることができる。 Further, the shaft portion of the upper member of the first member can be made to penetrate and slide through the second member.

本発明の吊り戸の下部振止装置の床面設置部材によれば、ガイドピンを、上端部に磁石を設け、下方に開口する空間を形成した第１部材と、該第１部材の下方に開口する空間内に嵌入可能に形成した第２部材とで構成し、収納状態で、第１部材がケース内に没入するとともに、第２部材が第１部材の下方に開口する空間内に嵌入した状態となり、この状態から、第１部材が磁力によって吸引されてケース内から上昇する際に、第１部材に従動して第２部材が上昇するようにすることにより、ガイドピンの突出長さを確保しながら、ガイドピン及びケースを含む床面設置部材の高さ方向の寸法を小さく抑えることができる。
さらに、ケース内に没入した第１部材が上昇するときに、ケースにガイドされて上昇するため、ケースの内周面と第１部材の外周面との間のクリアランスの精度で第１部材を上昇させることができ、上昇時の第１部材の吊り戸本体の幅方向の寸法精度を高めることで、ガイドピンを吊り戸本体の案内溝内に正確に挿入されるようにすることができる。 According to the floor surface installation member of the lower anti-vibration device of the hanging door of the present invention, the guide pin is provided in the upper end portion of the first member in which a magnet is provided to form a space to open downward, and below the first member. It is composed of a second member formed so as to be fitted in the opening space, and in the stored state, the first member is immersed in the case and the second member is fitted in the space opened below the first member. From this state, when the first member is attracted by the magnetic force and rises from the inside of the case, the protrusion length of the guide pin is increased by following the first member and raising the second member. While ensuring, the dimensions of the floor installation member including the guide pin and the case in the height direction can be kept small.
Further, when the first member immersed in the case rises, it is guided by the case and rises, so that the first member is raised with the accuracy of the clearance between the inner peripheral surface of the case and the outer peripheral surface of the first member. By increasing the dimensional accuracy in the width direction of the hanging door main body of the first member when ascending, the guide pin can be accurately inserted into the guide groove of the hanging door main body.

また、前記第１部材に設けた磁石の外周面が、第１部材の外周面を構成するようにすることにより、第１部材に径が大きい（磁力が大きい）磁石を用いることができ、ガイドピンを、吊り戸本体に設置される案内溝に配設した磁石又は磁性体により確実に吸引させることができ、これにより、例えば、案内溝に配設するガイドピンが吸引される部材を、磁性体のみから構成することができる。 Further, by making the outer peripheral surface of the magnet provided on the first member constitute the outer peripheral surface of the first member, a magnet having a large diameter (large magnetic force) can be used for the first member, and a guide can be used. The pin can be reliably attracted by the magnet or magnetic material arranged in the guide groove installed in the hanging door body, whereby, for example, the member on which the guide pin arranged in the guide groove is attracted is magnetically attracted. It can consist only of the body.

また、前記第１部材に従動して第２部材が上昇する際に、ケースの内周面にガイドされて上昇するようにすることにより、ケースの内周面と第２部材の下部の外周面との間のクリアランスの精度で第２部材を上昇させることができ、上昇時の第２部材の幅方向の寸法精度を高めること、そして、第２部材の上部によって第１部材がガイドされ、第１部材の吊り戸本体の幅方向の寸法精度を高めることで、ガイドピンを吊り戸本体の案内溝内に一層正確に挿入されるようにすることができる。 Further, when the second member rises in accordance with the first member, the inner peripheral surface of the case and the outer peripheral surface of the lower portion of the second member are guided by the inner peripheral surface of the case to rise. The second member can be raised with the accuracy of the clearance between the second member, the dimensional accuracy of the second member in the width direction at the time of raising is improved, and the first member is guided by the upper part of the second member. By increasing the dimensional accuracy in the width direction of the hanging door main body of one member, the guide pin can be inserted more accurately into the guide groove of the hanging door main body.

また、前記第１部材の上部部材の軸部が、第２部材を貫通、摺動するようにすることにより、ガイドピンの強度を高めることができるとともに、第１部材及び第２部材が相互にガイドし合い、第１部材及び第２部材の吊り戸本体の幅方向の寸法精度を高めることで、ガイドピンを吊り戸本体の案内溝内に一層正確に挿入されるようにすることができる。 Further, by allowing the shaft portion of the upper member of the first member to penetrate and slide through the second member, the strength of the guide pin can be increased, and the first member and the second member are mutually attached. By guiding each other and increasing the dimensional accuracy of the first member and the second member in the width direction of the hanging door main body, the guide pin can be inserted more accurately into the guide groove of the hanging door main body.

図１〜図３に、本発明の吊り戸の下部振止装置の床面設置部材の第１実施例を示す。
この吊り戸の下部振止装置の床面設置部材１は、床面に設置されるケース２に、吊り戸本体Ｄの案内溝Ｇに配設した磁石又は磁性体Ｍに吸引される磁石４１を配設したガイドピン３を上方に突出可能に収納するようにしたもので、ガイドピン３を、上端部に磁石４１を設け、下方に開口する空間４２を形成した第１部材４と、この第１部材４の下方に開口する空間４２内に嵌入可能に形成した第２部材５とで構成し、収納状態で、第１部材４がケース２内に没入するとともに、第２部材５が第１部材４の下方に開口する空間４２内に嵌入した状態となり、この状態から、第１部材４が磁力によって吸引されてケース２内から上昇する際に、第１部材４に従動して第２部材５が上昇するように構成されている。 1 to 3 show a first embodiment of a floor surface mounting member of the lower vibration device for a hanging door of the present invention.
The floor surface installation member 1 of the lower vibration damping device of the hanging door has a magnet 41 arranged in the guide groove G of the hanging door main body D or a magnet 41 attracted by the magnetic body M in the case 2 installed on the floor surface. The arranged guide pins 3 are housed so as to be able to project upward. The guide pins 3 are provided with a magnet 41 at the upper end thereof to form a space 42 that opens downward, and a first member 4 thereof. It is composed of a second member 5 formed so as to be fitted in a space 42 that opens below the first member 4, the first member 4 is immersed in the case 2 in the stored state, and the second member 5 is the first. It is in a state of being fitted into the space 42 that opens below the member 4, and from this state, when the first member 4 is attracted by a magnetic force and rises from the inside of the case 2, the second member is driven by the first member 4. 5 is configured to rise.

ケース２は鍔部２１を備えた円筒体からなり、内周部の対向する２箇所に縦方向の有端のスリット溝２２を備えている。
このスリット溝２２に沿って、第２部材５に形成された摺動突起５１が摺動するようにされている。
また、ケース２の鍔部２１の内面側は、上下方向に所定幅を有する内周面２０ａが形成されており、ケース２内に没入した第１部材４が上昇するときに、この内周面２０ａにガイドされて上昇するようにしている。 The case 2 is formed of a cylindrical body provided with a flange portion 21, and is provided with slit grooves 22 having an end in the vertical direction at two opposite positions on the inner peripheral portion.
The sliding protrusion 51 formed on the second member 5 slides along the slit groove 22.
Further, an inner peripheral surface 20a having a predetermined width in the vertical direction is formed on the inner surface side of the flange portion 21 of the case 2, and when the first member 4 immersed in the case 2 rises, this inner peripheral surface is formed. It is guided by 20a so that it rises.

ガイドピン３は、ケース２に直接摺動可能に収納された第１部材４と、この第１部材４の内部に摺動可能に収納された第２部材５とで構成するようにしている。 The guide pin 3 is composed of a first member 4 slidably housed in the case 2 and a second member 5 slidably housed inside the first member 4.

第１部材４は、上端部に磁石４１を設け、下方に開口する空間４２を形成するようにしている。
より具体的には、第１部材４は、断面がＴ字状の成形品からなる上部部材４３と、この上部部材４３の軸部４３ａに嵌入した磁石４１と、下方に開口する空間４２を形成した下部部材４４と、上部部材４３の軸部４３ａに嵌合するプッシュナットからなる固定部材４５とで構成するようにしている。
これにより、上端部に磁石４１を配設するようにしたガイドピン３である第１部材４の構造を簡易化して、その製造コストを低廉にできる。 The first member 4 is provided with a magnet 41 at the upper end portion so as to form a space 42 that opens downward.
More specifically, the first member 4 forms an upper member 43 made of a molded product having a T-shaped cross section, a magnet 41 fitted in the shaft portion 43a of the upper member 43, and a space 42 that opens downward. The lower member 44 is made of a fixed member 45 formed of a push nut that fits into the shaft portion 43a of the upper member 43.
As a result, the structure of the first member 4 which is the guide pin 3 in which the magnet 41 is arranged at the upper end portion can be simplified, and the manufacturing cost thereof can be reduced.

この場合において、第１部材４は、磁石４１を除いて、オーステナイト系のステンレススチール、黄銅、マグネシウム合金、アルミニウム合金等の金属や、ポリアミド（ＰＡ）、ポリアセタール（ＰＯＭ）、ポリカーボネート（ＰＣ）等のエンジニアリングプラスチック等の合成樹脂（複合材料を含む。）等の非磁性体材料からなる成形品で構成することができる。
このように、第１部材４を非磁性体材料で構成することにより、磁石４１の磁力が、第１部材４によって遮られることがないため、ガイドピン３である第１部材４を、吊り戸本体Ｄの案内溝Ｇに配設した磁石又は磁性体Ｍにより確実に吸引させることができる。 In this case, except for the magnet 41, the first member 4 is made of austenite-based stainless steel, brass, magnesium alloy, aluminum alloy or other metal, polyamide (PA), polyacetal (POM), polycarbonate (PC) or the like. It can be composed of a molded product made of a non-magnetic material such as a synthetic resin (including a composite material) such as engineering plastic.
In this way, by forming the first member 4 with a non-magnetic material, the magnetic force of the magnet 41 is not blocked by the first member 4, so that the first member 4, which is the guide pin 3, is mounted on the hanging door. It can be reliably attracted by the magnet or magnetic body M arranged in the guide groove G of the main body D.

また、第１部材４に設けた磁石４１の外周面が、第１部材４の外周面を構成するようにすることができる。
これにより、第１部材４に径が大きい（磁力が大きい）磁石を用いることができ、ガイドピン３を、吊り戸本体Ｄに設置される案内溝Ｇに配設した磁石又は磁性体Ｍにより確実に吸引させることができ、例えば、案内溝Ｇに配設する、ガイドピン３である第１部材４が吸引される部材を、磁性体のみから構成することができる。 Further, the outer peripheral surface of the magnet 41 provided on the first member 4 can form the outer peripheral surface of the first member 4.
As a result, a magnet having a large diameter (large magnetic force) can be used for the first member 4, and the guide pin 3 is reliably secured by the magnet or magnetic body M arranged in the guide groove G installed in the hanging door main body D. For example, the member for which the first member 4 which is the guide pin 3 is attracted, which is arranged in the guide groove G, can be made of only a magnetic material.

第２部材５は、第１部材４の下方に開口する空間４２内に嵌入可能に形成するようにしている。
より具体的には、第２部材５は、第１部材４の空間４２内に嵌入可能に形成した上部５０ａと、第１部材４よりも若干大きな径に形成した円盤形状の下部５０ｂとからなり、下部５０ｂにケース２のスリット溝２２に沿って摺動する摺動突起５１が形成され、上部５０ａに第１部材４の下部部材４４に形成されたスリット孔４６に嵌まり込んで、第１部材４と第２部材５の抜け止め及び第２部材５に対する第１部材４の回り止めを行うための、ばね５３によって付勢されるようにしたピン部材５２を配設するようにしている。 The second member 5 is formed so as to be fitted into the space 42 that opens below the first member 4.
More specifically, the second member 5 includes an upper portion 50a formed so as to fit into the space 42 of the first member 4, and a disk-shaped lower portion 50b formed having a diameter slightly larger than that of the first member 4. A sliding protrusion 51 that slides along the slit groove 22 of the case 2 is formed in the lower portion 50b, and is fitted into the slit hole 46 formed in the lower member 44 of the first member 4 in the upper portion 50a. A pin member 52 urged by a spring 53 is provided to prevent the member 4 and the second member 5 from coming off and to prevent the first member 4 from rotating with respect to the second member 5.

この場合において、第２部材５も、第１部材と同様の非磁性体材料からなる成形品で構成することができる。 In this case, the second member 5 can also be made of a molded product made of the same non-magnetic material as the first member.

そして、上記実施例の吊り戸の下部振止装置の床面設置部材１は、ケース２にピン２３を配設し、第１部材４及び第２部材５にピン２３が入り込むスリット溝４７、５４をそれぞれ形成することにより、ガイドピン３の位置決め（抜け止め）ができるようにしている。 Then, in the floor surface installation member 1 of the lower vibration device of the hanging door of the above embodiment, the pin 23 is arranged in the case 2, and the slit grooves 47 and 54 into which the pin 23 enters the first member 4 and the second member 5. The guide pin 3 can be positioned (prevented from coming off) by forming each of the above.

ところで、上記実施例の吊り戸の下部振止装置の床面設置部材１は、ガイドピン３を、ケース２に対して偏心して配設するようにしている。
これにより、ケース２を床に設置する際に（この場合、ケース２は、合成樹脂等の材料で形成したアウター部材（図示省略）を介して、床に設置するようにする。）、ケース２を回転することによって、ガイドピン３の吊り戸本体Ｄの案内溝Ｇに対する位置調整を、容易に、かつ、何度でも行うことができるようにしている。 By the way, the floor surface installation member 1 of the lower vibration device of the hanging door of the above embodiment is arranged so that the guide pin 3 is eccentrically arranged with respect to the case 2.
As a result, when the case 2 is installed on the floor (in this case, the case 2 is installed on the floor via an outer member (not shown) formed of a material such as synthetic resin). The position of the guide pin 3 with respect to the guide groove G of the hanging door main body D can be easily and many times adjusted by rotating the guide pin 3.

なお、吊り戸本体Ｄは、図では省略しているが、天井レールにランナーを介して走行自在に吊り下げられている。 Although the hanging door main body D is omitted in the drawing, it is suspended from the ceiling rail via a runner so as to be freely travelable.

次に、本実施例の吊り戸の下部振止装置の床面設置部材の作用を説明する。
この吊り戸の下部振止装置の床面設置部材１は、収納状態では、第１部材４がケース２内に没入するとともに、第２部材５が第１部材４の下方に開口する空間４２内に嵌入した状態となる。
これにより、この吊り戸の下部振止装置の床面設置部材１は、ガイドピン３の突出長さを確保しながら、ガイドピン３及びケース２を含む床面設置部材１の高さ方向の寸法を小さく抑えることができる。 Next, the operation of the floor surface installation member of the lower vibration device of the hanging door of this embodiment will be described.
In the stowed state, the floor surface installation member 1 of the lower anti-vibration device of the hanging door has a space 42 in which the first member 4 is immersed in the case 2 and the second member 5 is opened below the first member 4. It will be in the state of being fitted in.
As a result, the floor surface installation member 1 of the lower anti-vibration device of the hanging door has dimensions in the height direction of the floor surface installation member 1 including the guide pin 3 and the case 2 while ensuring the protruding length of the guide pin 3. Can be kept small.

この状態で、吊り戸本体Ｄが、床面に設置された床面設置部材１の上方位置に来ると、案内溝Ｇに配設した磁石又は磁性体Ｍに、ガイドピン３としての第１部材４の上端部に設けた磁石４１の作用によって、第１部材４が吸引されてケース２内から上昇し、この際に、第１部材４に従動して第２部材５も上昇する。
これにより、ケース２内に没入した第１部材４が上昇するときに、ケース２の上縁の内周面２０ａにガイドされて上昇するため、ケース２の上縁の内周面２０ａと第１部材４の外周面との間のクリアランスの精度で第１部材４を上昇させることができ、上昇時の第１部材４の吊り戸本体Ｄの幅方向の寸法精度を高めることで、ガイドピン３を吊り戸本体Ｄの案内溝Ｇ内に正確に挿入されるようにすることができる。
さらに、本実施例においては、第１部材４に従動して上昇する第２部材５の下部５０ｂが、ケース２の内周面２０ｂにガイドされて上昇するため、ケース２の内周面２０ｂと第２部材５の下部５０ｂの外周面との間のクリアランスの精度で第２部材５を上昇させることができ、上昇時の第２部材５の幅方向の寸法精度を高めること、そして、第２部材５の上部５０ａによって第１部材４がガイドされ、第１部材４の吊り戸本体Ｄの幅方向の寸法精度を高めることで、ガイドピン３を吊り戸本体Ｄの案内溝Ｇ内に一層正確に挿入されるようにすることができる。 In this state, when the hanging door main body D comes to a position above the floor surface installation member 1 installed on the floor surface, the first member as the guide pin 3 is attached to the magnet or magnetic body M arranged in the guide groove G. By the action of the magnet 41 provided at the upper end portion of 4, the first member 4 is attracted and rises from the inside of the case 2, and at this time, the second member 5 also rises in accordance with the first member 4.
As a result, when the first member 4 immersed in the case 2 rises, it is guided by the inner peripheral surface 20a of the upper edge of the case 2 and rises, so that the inner peripheral surface 20a and the first upper edge of the case 2 rise. The first member 4 can be raised with the accuracy of the clearance between the outer peripheral surface of the member 4 and the guide pin 3 by increasing the dimensional accuracy in the width direction of the hanging door body D of the first member 4 at the time of raising. Can be accurately inserted into the guide groove G of the hanging door body D.
Further, in the present embodiment, the lower portion 50b of the second member 5 that rises in accordance with the first member 4 is guided by the inner peripheral surface 20b of the case 2 and rises, so that the lower portion 50b and the inner peripheral surface 20b of the case 2 rise. The second member 5 can be raised with the accuracy of the clearance between the lower portion 50b of the second member 5 and the outer peripheral surface, the dimensional accuracy in the width direction of the second member 5 at the time of raising is improved, and the second member 5 is raised. The first member 4 is guided by the upper portion 50a of the member 5, and the guide pin 3 is more accurately placed in the guide groove G of the hanging door body D by increasing the dimensional accuracy of the hanging door body D of the first member 4 in the width direction. Can be inserted into.
