本発明によれば、ガイドシューを容易に交換することができる。
According to the present invention, the guide shoe can be easily replaced.
以下図面について、本発明の一実施の形態を詳述する。
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
図１は、本実施の形態におけるガイド装置１の分解斜視図を示す。ガイド装置１は、ガイドシュー１０及びホルダー２０から構成される。
FIG. 1 is an exploded perspective view of the guide device 1 according to the present embodiment. The guide device 1 includes a guide shoe 10 and a holder 20.
ガイドシュー１０は、凹部形状１１を有して構成され、ホルダー２０に保持される。ホルダー２０に保持された状態において凹部形状１１の内面１２は、ガイドレールと係合して摺動する。なお凹部形状の外面１３には複数の溝が形成される。この複数の溝は、ガイドシュー１０を安価に製造するためのものである。強度を保つようにして部材を間引くことにより材料費を削減することができる。
The guide shoe 10 is configured to have a concave shape 11 and is held by the holder 20. When held by the holder 20, the inner surface 12 of the concave shape 11 engages with the guide rail and slides. A plurality of grooves are formed in the outer surface 13 having a concave shape. The plurality of grooves are for manufacturing the guide shoe 10 at a low cost. The material cost can be reduced by thinning out the members while maintaining the strength.
ホルダー２０は、シュー固定具２１、レバー２２、爪２３及び凹部形状２４を有して構成され、昇降体である乗りかご及び釣合おもりの外面にボルト締結により固定される。シュー固定具２１及びレバー２２は、一体に形成されており、左右対称のシュー固定具２１及びレバー２２を一対としてホルダー２０の上部及び下部に設けられる。
The holder 20 includes a shoe fixing tool 21, a lever 22, a claw 23, and a recessed portion 24, and is fixed to the outer surface of the elevator car and the counterweight by bolt fastening. The shoe fixture 21 and the lever 22 are integrally formed, and are provided on the upper and lower portions of the holder 20 as a pair of symmetrical shoe fixture 21 and lever 22.
また爪２３も同様に左右対称の爪２３がホルダー２０の上部及び下部に設けられる。凹部形状２４は、ガイドシュー１０の外幅寸法と略同一又は若干大きく、ガイドシュー１０を収納可能とする形状を有する。ホルダー２０は、これらシュー固定具２１、レバー２２、爪２３及び凹部形状２４により、ガイドシュー１０を取り外し可能に保持する。
Similarly, the claw 23 is provided with symmetrical claw 23 on the upper and lower parts of the holder 20. The concave shape 24 is substantially the same as or slightly larger than the outer width dimension of the guide shoe 10 and has a shape that allows the guide shoe 10 to be accommodated. The holder 20 detachably holds the guide shoe 10 by the shoe fixing tool 21, the lever 22, the claw 23, and the recess shape 24.
なおホルダー２０は、樹脂を材料として一体成型により作製されるが、材料は樹脂に限らず、アルミや鋳鉄を用いて鋳物品として作製されるとしてもよい。
The holder 20 is manufactured by integral molding using a resin as a material, but the material is not limited to the resin, and may be manufactured as a cast article using aluminum or cast iron.
ここでガイドシュー１０をホルダー２０に固定する際の固定作業について説明する。まずホルダー２０の上部及び下部にそれぞれ設けられている左右対称の一対のレバー２２のうち、何れか一対のレバー２２（ここでは上部の一対のレバー２２とする）を外側から指でつまんで内側に向けて力を加えることによりレバー２２を内側に弾性変形させる。
Here, fixing work when the guide shoe 10 is fixed to the holder 20 will be described. First, of a pair of symmetrical levers 22 provided on the upper and lower parts of the holder 20, either one pair of levers 22 (here, the upper pair of levers 22) is pinched with fingers from the outside to the inside. The lever 22 is elastically deformed inward by applying a force toward it.
レバー２２を内側に弾性変形させると、レバー２２と一体に形成される左右のシュー固定具２１がそれぞれ１～２ｍｍ程度外側に広がる。外側に広がった状態における左右のシュー固定具２１間の距離は、ガイドシュー１０の外幅寸法よりも大きくなる。
When the lever 22 is elastically deformed inward, the left and right shoe fasteners 21 formed integrally with the lever 22 spread outward by about 1 to 2 mm. The distance between the left and right shoe fixtures 21 in a state of spreading outward is larger than the outer width dimension of the guide shoe 10.
次いでレバー２２を指でつまんだままの状態で外側に広がったシュー固定具２１間からガイドシュー１０を上方から下方に向けて挿入することによりガイドシュー１０をホルダー２０に設置する。その後レバー２２から指を離す。
Next, the guide shoe 10 is installed in the holder 20 by inserting the guide shoe 10 from the upper side to the lower side between the shoe fixtures 21 spreading outward while the lever 22 is pinched with fingers. Then release the lever 22.
レバー２２から指を離すと、レバー２２は弾性変形前の状態に戻る。レバー２２が弾性変形前の状態に戻ると、シュー固定具２１間の距離も元の状態に戻る。元の状態に戻ったシュー固定具２１間の距離はガイドシュー１０の外幅寸法よりも小さいため、シュー固定具２１が元の状態に戻ることでガイドシュー１０は昇降方向（Ｚ方向）に対して固定されることになる。
When the finger is released from the lever 22, the lever 22 returns to the state before elastic deformation. When the lever 22 returns to the state before elastic deformation, the distance between the shoe fixtures 21 also returns to the original state. Since the distance between the shoe fixtures 21 returned to the original state is smaller than the outer width dimension of the guide shoe 10, the guide shoe 10 is moved in the ascending / descending direction (Z direction) when the shoe fixture 21 returns to the original state. Will be fixed.
またガイドシュー１０は、爪２３によりガイドレール方向（Ｘ方向）に対して固定され、Ｙ方向に対してはホルダー２０がガイドシュー１０を収納する凹部形状２４を有していることからこの凹部形状２４により固定される。以上によりガイドシュー１０はホルダー２０に固定され、ホルダー２０はガイドシュー１０を保持する。
Further, the guide shoe 10 is fixed to the guide rail direction (X direction) by the claw 23, and since the holder 20 has a concave shape 24 for accommodating the guide shoe 10 in the Y direction, this concave shape is used. 24 is fixed. As described above, the guide shoe 10 is fixed to the holder 20, and the holder 20 holds the guide shoe 10.
次いでガイドシュー１０の交換が必要となった際の交換作業について説明する。まずホルダー２０の上部及び下部にそれぞれ設けられている左右対称の一対のレバー２２のうち、何れか一対のレバー２２（ここでは上部の一対のレバー２２とする）を外側から指でつまんで内側に向けて力を加えることによりレバー２２を内側に弾性変形させる。
Next, the replacement work when the guide shoe 10 needs to be replaced will be described. First, of a pair of symmetrical levers 22 provided on the upper and lower parts of the holder 20, either one pair of levers 22 (here, the upper pair of levers 22) is pinched with fingers from the outside to the inside. The lever 22 is elastically deformed inward by applying a force toward it.
上述してきたようにレバー２２を弾性変形させるとシュー固定具２１が外側に広がりシュー固定具２１間の距離が大きくなるため、シュー固定具２１間の距離が大きくなった状態で劣化したガイドシュー１０取り外し、新たなガイドシュー１０に交換した後、レバー２２から指を離す。レバー２２が弾性変形前の状態に戻るとともにシュー固定具２１間の距離も元の状態に戻るため、新たなガイドシュー１０はシュー固定具２１及び爪２３により固定される。以上により劣化したガイドシュー１０が新たなガイドシュー１０に交換され、ホルダー２０は新たなガイドシュー１０を保持する。
As described above, when the lever 22 is elastically deformed, the shoe fixture 21 spreads outward and the distance between the shoe fixtures 21 increases. Therefore, the guide shoe 10 deteriorated with the distance between the shoe fixtures 21 increased. After removing and replacing with a new guide shoe 10, the finger is released from the lever 22. Since the lever 22 returns to the state before elastic deformation and the distance between the shoe fixtures 21 also returns to the original state, the new guide shoe 10 is fixed by the shoe fixtures 21 and the claws 23. The guide shoe 10 deteriorated as described above is replaced with a new guide shoe 10, and the holder 20 holds the new guide shoe 10.
図２は、ガイドシュー１０をホルダー２０に固定した状態のガイド装置１の斜視構成を示す。ガイドシュー１０は、シュー固定具２１により昇降方向（Ｚ方向）に対して固定され、また爪２３によりガイドレール方向（Ｘ方向）に対して固定される。Ｙ方向に対しては凹部形状２４により固定される。なお上述してきたようにシュー固定具２１と一体に形成されるレバー２２を押圧することにより保持状態を解除することができる。
FIG. 2 shows a perspective configuration of the guide device 1 in a state where the guide shoe 10 is fixed to the holder 20. The guide shoe 10 is fixed in the ascending / descending direction (Z direction) by the shoe fixture 21 and fixed in the guide rail direction (X direction) by the claw 23. It is fixed by the concave shape 24 in the Y direction. As described above, the holding state can be released by pressing the lever 22 formed integrally with the shoe fixture 21.
図３は、シュー固定具２１及びレバー２２の正面構成を示す。シュー固定具２１は、ガイドシュー１０との接触面において突起２１１を有する。この突起２１１によりガイドシュー１０との接触面積を小さくして押圧力を大きくすることができる。なおここでのシュー固定具２１は、突起２１１を有するとしたがこれに限らず、突起２１１を有さず平面であってもよい。
FIG. 3 shows a front configuration of the shoe fixture 21 and the lever 22. The shoe fixture 21 has a protrusion 211 on the contact surface with the guide shoe 10. The projection 211 can reduce the contact area with the guide shoe 10 and increase the pressing force. In addition, although the shoe fixing tool 21 here has the protrusion 211, it is not restricted to this, A flat surface without the protrusion 211 may be sufficient.
またレバー２２を外側から指でつまんで内側に向けて力Ｆ１を加えると、レバー２２は内側に弾性変形し、レバー２２が内側に弾性変形することでこのレバー２２と一体に形成されるシュー固定具２１が外側に広がると説明してきたが、具体的には力Ｆ１は、一般的な成人の握力である２０ｋｇｆを想定している。またレバー２２の長さＬ１は、２０ｋｇｆの押圧力をレバー２２に付勢したときにシュー固定具２１が外側に１～２ｍｍ程度開放されるように調節して設計される。
When the lever 22 is pinched with a finger from the outside and a force F1 is applied inward, the lever 22 is elastically deformed inward, and the lever 22 is elastically deformed inward so that the shoe is fixed integrally with the lever 22. Although it has been described that the tool 21 spreads outward, specifically, the force F1 is assumed to be 20 kgf, which is a general adult's gripping force. The length L1 of the lever 22 is designed so that the shoe fixture 21 is opened about 1 to 2 mm outward when a pressing force of 20 kgf is applied to the lever 22.
図４は、ガイド装置１を乗りかご及び釣合おもりに設置した状態の上面構成を示す。ガイド装置１が乗りかご及び釣合おもりに設置された状態において、ガイドシュー１０はホルダー２０に保持され、ホルダー２０は乗りかご及び釣合おもりの外面３０にボルト３１により締結されて固定される。なおガイドレール４０は、昇降路を構成する建屋壁５０に延在して固定される。
FIG. 4 shows an upper surface configuration in a state where the guide device 1 is installed on the car and the counterweight. In a state where the guide device 1 is installed on the car and the counterweight, the guide shoe 10 is held by the holder 20, and the holder 20 is fastened and fixed to the outer surface 30 of the car and the counterweight by a bolt 31. In addition, the guide rail 40 is extended and fixed to the building wall 50 which comprises a hoistway.
ガイド装置１は、乗りかご及び釣合おもりが図示しない駆動系により上下方向に昇降すると、ガイドシュー１０をガイドレール４０に係合して摺動させることにより、乗りかご及び釣合おもりをガイドレール４０に沿って案内する。なおガイド装置１は、例えば乗りかごを正面から見たときに乗りかごの左右の外面３０の上部及び下部にそれぞれ一つずつ合計４つ設置される。
When the car and the counterweight are moved up and down by a drive system (not shown), the guide device 1 engages and slides the guide shoe 10 on the guide rail 40, thereby moving the car and the counterweight to the guide rail. Guide along 40. For example, when the car is viewed from the front, for example, a total of four guide devices 1 are installed respectively on the upper and lower parts of the left and right outer surfaces 30 of the car.
以上のように本実施の形態によれば、ガイドシュー１０及びガイドシュー１０を取り外し可能に保持するホルダー２０から構成されるガイド装置において、ホルダー２０はシュー固定具２１及びレバー２２を備え、レバー２２を一定の押圧力で押圧して弾性変形させることにより、レバー２２と一体に形成されるシュー固定具２１間の距離を広げ、距離を広げた状態でシュー固定具２１間からガイドシュー１０を挿入して設置した後、レバー２２に対する押圧を解除することでレバー２２の弾性変形及びシュー固定具２１間の距離を復元してガイドシュー１０をホルダー２０に固定するようにしたので、工具がなくともガイドシュー１０を固定及び交換することができる。
As described above, according to the present embodiment, in the guide device including the guide shoe 10 and the holder 20 that removably holds the guide shoe 10, the holder 20 includes the shoe fixture 21 and the lever 22, and the lever 22 Is pressed and elastically deformed by a certain pressing force, thereby increasing the distance between the shoe fixtures 21 formed integrally with the lever 22 and inserting the guide shoe 10 between the shoe fixtures 21 with the distance extended. After the installation, the pressure on the lever 22 is released to restore the elastic deformation of the lever 22 and the distance between the shoe fixtures 21 so that the guide shoe 10 is fixed to the holder 20. The guide shoe 10 can be fixed and exchanged.
また本実施の形態によれば、ホルダー２０はシュー固定具２１及びレバー２２を左右対称に備え、ガイドシュー１０の固定及び交換の際には左右のレバー２２を一定の押圧力で押圧して弾性変形させることでシュー固定具２１間の距離を広げるようにしたので、例えばシュー固定具２１及びレバー２２が左右の何れか一方にしかない場合と比較して、指にかかる荷重を半分に減らすことができる。またレバー２２の長さＬ１は、一般的な成人の握力を想定して力Ｆ１で押圧したときにレバー２２が弾性変形するように設計されるので、指にかかる荷重を減らすことができる。よって作業負荷を軽減することができる。
Further, according to the present embodiment, the holder 20 includes the shoe fixture 21 and the lever 22 symmetrically, and when the guide shoe 10 is fixed and replaced, the left and right levers 22 are pressed with a constant pressing force to be elastic. Since the distance between the shoe fixtures 21 is increased by the deformation, for example, the load applied to the finger can be reduced by half compared to the case where the shoe fixture 21 and the lever 22 are only on either the left or right side. it can. Further, the length L1 of the lever 22 is designed so that the lever 22 is elastically deformed when pressed with the force F1 assuming a general adult's gripping force, so that the load on the finger can be reduced. Therefore, the work load can be reduced.
なお本実施の形態において、シュー固定具２１及びレバー２２が設けられる部位は、図４に示す上面視においてホルダー２０の乗りかごの外面３０と接触する平面部からガイドレール４０に向かって突出する形状を取っており、その上辺及び下辺において外面３０と接触する平面部に接続された根元側の部位との間に溝を設けてガイドレール４０側にシュー固定具２１及びレバー２２が設けられている。このような構成をとることによって、一般的な成人の握力Ｆ１で押圧したときにレバー２２が弾性変形可能に構成し易くなり、また安定してガイドシュー１０を保持する形状を実現できる。
In the present embodiment, the portion where the shoe fixing tool 21 and the lever 22 are provided has a shape that protrudes toward the guide rail 40 from a flat portion that contacts the outer surface 30 of the car of the holder 20 in a top view shown in FIG. A groove is provided between the upper side and the lower side of the base portion connected to the flat surface portion that contacts the outer surface 30, and the shoe fixture 21 and the lever 22 are provided on the guide rail 40 side. . By adopting such a configuration, the lever 22 can be easily configured to be elastically deformable when pressed with a general adult's gripping force F1, and a shape that stably holds the guide shoe 10 can be realized.
また図１又は図２に示すように、ホルダー２０の乗りかごの外面３０と接触する平面部に接続された根元側の部位には爪等は設けないことにより、工具がなくとも人力によりガイドシュー１０の交換する作業を容易としながら、ガイドシュー１０を保持する強度を確保している。そしてさらに、爪２３が設けられた側面部には、ガイドシュー１０を保持する側とは反対側の面に外面３０と接触する平面部から形成された山状の補強部を設け、ガイドシュー１０を保持しながら、乗りかごの重量がかかった際などの荷重にも耐えられる強度を確保している。そしてこの山状の補強部はシュー固定具２１及びレバー２２を避けて形成されているため、一般的な成人の握力Ｆ１で押圧したときにレバー２２が弾性変形可能とし、またレバー２２を押圧した際のシュー固定具２１の可動を妨げることもない。
Also, as shown in FIG. 1 or FIG. 2, the claw or the like is not provided at the base portion connected to the flat surface portion of the holder 20 that contacts the outer surface 30 of the car. The strength of holding the guide shoe 10 is ensured while the work of exchanging 10 is made easy. Further, the side surface portion provided with the claw 23 is provided with a mountain-shaped reinforcing portion formed from a flat surface portion in contact with the outer surface 30 on the surface opposite to the side holding the guide shoe 10. While maintaining a sufficient strength to withstand loads such as when the weight of the car is applied. Since the mountain-shaped reinforcing portion is formed so as to avoid the shoe fixture 21 and the lever 22, the lever 22 can be elastically deformed when pressed with a general adult's gripping force F 1, and the lever 22 is pressed. The movement of the shoe fixing tool 21 at that time is not hindered.
よって本実施の形態によれば、工具を準備することなく、ボルトなどの締結体が不要であることから締結体を誤って落下させることもなく、更には大きな作業負荷をかけることもないので、ガイドシュー１０を容易に交換することができる。
Therefore, according to the present embodiment, without preparing a tool, since a fastening body such as a bolt is unnecessary, the fastening body is not accidentally dropped, and further, a large work load is not applied. The guide shoe 10 can be easily replaced.
