Description

本発明は、レールに取り付けられ、このレールに案内されるランナーを制動するブレーキ装置に関する。   The present invention relates to a brake device that is attached to a rail and brakes a runner guided by the rail.

この種のブレーキ装置としては、弓なりに湾曲し、その頂部がランナーに付勢接触し、これによりランナーを制動する制動部として機能するバネ材を有しており、バネ材の頂部の高さ位置を変えることによりその付勢力を調節するようになっているものがある。この付勢力を調節する手段としては、前記バネ材の先端部の高さ位置をネジにより変え、これによりバネ材の頂部の高さ位置を変えるもの( 特許文献１及び２参照) 、前記バネ材の基端部の高さ位置をネジにより変え、これによりバネ材の頂部の高さ位置を変えるもの( 特許文献２参照) 等がある。   This type of brake device has a spring material that is curved like a bow, the top of which is in urging contact with the runner, thereby functioning as a braking portion that brakes the runner, and the height position of the top of the spring material Some of them are designed to adjust their biasing force by changing. As means for adjusting the urging force, the height position of the tip portion of the spring material is changed by a screw, thereby changing the height position of the top portion of the spring material (see Patent Documents 1 and 2), and the spring material The height position of the base end portion of the spring is changed by a screw, thereby changing the height position of the top portion of the spring material (see Patent Document 2).

特開平０７−２８６４７４号公報JP 07-286474 A 特許第２９０９７０３号公報Japanese Patent No. 2909703

ところが、付勢力を調節する手段として、バネ材の先端部の高さ位置を変える手段を用いた場合、バネ材の頂部の高さ位置を大きく変えることができないことから、高さ寸法の高いレールに使用することができない可能性があるという本質的な欠点を有する。もっとも、付勢力を調節する手段として、前記バネ材の基端部の高さ位置を変える手段を用いれば、前記バネ材の頂部の高さ位置を大きく変えることができるので、高さ寸法の高いレールに使用することが可能になるが、前記バネ材の基端部がベース部から浮いた状態で取り付けられており、前記バネ材の付勢力のみでランナーを制動する構成となっていることから、長期間使用することにより前記バネ材の付勢力が弱くなると、ブレーキ装置として機能しなくなる可能性があるという別の欠点を有している。   However, if the means for changing the height position of the tip of the spring material is used as means for adjusting the biasing force, the height position of the top of the spring material cannot be changed greatly. Has the essential disadvantage that it may not be usable. However, if the means for changing the height position of the base end portion of the spring material is used as means for adjusting the biasing force, the height position of the top portion of the spring material can be greatly changed, so that the height dimension is high. It can be used for rails, but the base end of the spring material is attached in a state of floating from the base, and the runner is braked only by the urging force of the spring material. If the urging force of the spring material becomes weak after long-term use, it has another disadvantage that it may not function as a brake device.

本発明は、上記事情に鑑みて創案されたものであって、その目的とするところは、高さ寸法の大きいレールにも対応することが可能であり、且つブレーキ装置として長寿命化を図ることが可能なブレーキ装置を提供することにある。   The present invention was devised in view of the above circumstances, and the object of the present invention is to cope with a rail having a large height and to extend the life of the brake device. It is an object of the present invention to provide a brake device capable of achieving the above.

上記課題を解決するために、本発明のブレーキ装置は、レールに取り付けられ、このレールに案内されるランナーを制動するブレーキ装置であって、レールに取り付けられるベース部と、基端部が前記ベース部にスライド移動可能に取り付けられた板バネとを備えており、前記板バネの先端部は、先端が開放され、弓なりに湾曲した板体であって、その頂部がランナーに付勢接触することによりランナーを制動するようになっており、前記ベース部には、前記板バネの基端部の移動路上に位置し、当該基端部がスライド移動することにより乗り上げ可能な凸部と、付勢接触により変位した前記板バネの先端部の開放端部が当接可能な当て止め部とが設けられていることを特徴としている。   In order to solve the above-described problems, a brake device according to the present invention is a brake device that is attached to a rail and brakes a runner guided by the rail, wherein a base portion attached to the rail and a base end portion are the base. A leaf spring attached to the portion so as to be slidable, and a distal end portion of the leaf spring is a plate body having a distal end opened and curved like a bow, and a top portion of the leaf spring is in urging contact with the runner. The base portion is positioned on the moving path of the base end portion of the leaf spring, and a convex portion that can be ridden by sliding the base end portion, and an urging force An abutting stop portion on which the open end portion of the distal end portion of the leaf spring displaced by the contact can abut is provided.

前記凸部には、前記板バネの基端部の高さ位置を変えるための傾斜面が、前記当て止め部には、前記板バネの先端部の開放端部が当接する高さ位置を変えるための傾斜面が設けられていることが好ましい。   The convex portion has an inclined surface for changing the height position of the base end portion of the leaf spring, and the stopper portion changes the height position at which the open end portion of the distal end portion of the leaf spring abuts. It is preferable that an inclined surface is provided.

本発明の請求項１に係るブレーキ装置による場合、板バネの基端部がスライド移動することによりベース部の凸部に乗り上げ、これにより当該板バネの先端部の頂部の高さ位置を変えることができるようになっている。よって、高さ寸法の高いレールにも対向することが可能になる。しかも、ランナーが板バネの先端部の頂部に付勢接触すると、当該板バネの先端部の開放端部が変位し、ベース部の当て止め部に当接する構成となっている。即ち、板バネの先端部の付勢力と、板バネの先端部の開放端部をベース部の当て止め部に当接させることとにより、ランナーの付勢接触による負荷を分散することができる構成となっているので、従来例のような板バネの付勢力のみでランナーを制動するブレーキ装置と比べて長寿命化を図ることができる。   In the brake device according to claim 1 of the present invention, the base end portion of the leaf spring slides on the convex portion of the base portion, thereby changing the height position of the top portion of the tip portion of the leaf spring. Can be done. Therefore, it is possible to face a rail having a high height. In addition, when the runner is urged into contact with the top of the tip of the leaf spring, the open end of the tip of the leaf spring is displaced and comes into contact with the contact stop of the base. That is, a configuration that can distribute the load caused by the urging contact of the runner by bringing the urging force of the tip of the leaf spring and the open end of the tip of the leaf spring into contact with the abutment portion of the base. Therefore, the service life can be extended as compared with the brake device that brakes the runner only by the urging force of the leaf spring as in the conventional example.

本発明の請求項２に係るブレーキ装置による場合、ベース部の凸部に板バネの基端部の高さ位置を変えるための傾斜面が設けられている。このため、板バネの基端部の高さ位置を微細に変化させることが可能になる。即ち、板バネの先端部の頂部の高さ位置を微細に変化させ、当該板バネの付勢力の微調整を行うことが可能になるので、ランナーに対して所望の制動を行うことができる。   In the brake device according to claim 2 of the present invention, the convex portion of the base portion is provided with an inclined surface for changing the height position of the base end portion of the leaf spring. For this reason, it becomes possible to change the height position of the base end part of a leaf | plate spring minutely. That is, since it becomes possible to finely adjust the height position of the top of the tip of the leaf spring and finely adjust the urging force of the leaf spring, desired braking can be performed on the runner.

本発明の請求項３に係るブレーキ装置による場合、ベース部１００の当て止め部に板バネの先端部の開放端部が当接する高さ位置を変えるための傾斜面が設けられている。このように板バネの先端部の開放端部が当接する高さ位置を変えることによっても板バネの先端部の付勢力を変えることができるので、板バネの付勢力の微調整を行う上でメリットがある。   In the brake device according to claim 3 of the present invention, an inclined surface for changing the height position at which the open end of the distal end portion of the leaf spring abuts on the stopper portion of the base portion 100 is provided. In this way, the biasing force of the tip of the leaf spring can be changed also by changing the height position where the open end of the tip of the leaf spring abuts. There are benefits.

As shown in FIG. 3 (b), the holding portion 110 has a first groove portion 111 provided upward in the drawing, and a second groove provided in communication with the first groove portion 111 and provided downward in the drawing. And a groove 112. The first groove 111 is provided with a hole 111 a for hooking a tool such as a screwdriver and sliding the base 100 on the rail 10. In the second groove portion 112, a long hole 112a communicating with the screw hole 211 of the leaf spring 200 is formed. A screw 300 shown in FIG. 2 is inserted into the long hole 112a.

また、ベース部１００には、第２の溝部１１２と連なり且つ板バネ２００の基端部２１０がスライド移動することにより乗り上げ可能な凸部１２０が設けられている。即ち、凸部１２０は板バネ２００の基端部２１０の移動路上に位置するように設けられている。この凸部１２０の一端部には、板バネ２００の基端部２１０の高さ位置を変えるための傾斜面１２１が設けられている。この傾斜面１２１は図３( ｂ) の左から右にかけて傾斜している。ベース部１００の他端部には、板バネ２００の先端部２２０の開放端部２２１が当接可能な当て止め部１３０が設けられている。この当て止め部１３０は凸部であって、その一端部に板バネ２００の先端部２２０の開放端部２２１が当接する高さ位置を変えるための傾斜面１３１が設けられている。この傾斜面１２１も図３( ｂ) の左から右にかけて傾斜している。   Further, the base portion 100 is provided with a convex portion 120 that is connected to the second groove portion 112 and can be ridden by sliding the base end portion 210 of the leaf spring 200. That is, the convex portion 120 is provided so as to be positioned on the moving path of the base end portion 210 of the leaf spring 200. An inclined surface 121 for changing the height position of the base end portion 210 of the leaf spring 200 is provided at one end portion of the convex portion 120. The inclined surface 121 is inclined from the left to the right in FIG. At the other end portion of the base portion 100, an abutting stop portion 130 with which the open end portion 221 of the distal end portion 220 of the leaf spring 200 can abut is provided. The stopper portion 130 is a convex portion, and an inclined surface 131 for changing the height position where the open end portion 221 of the tip end portion 220 of the leaf spring 200 abuts is provided at one end portion thereof. This inclined surface 121 is also inclined from the left to the right in FIG.

板バネ２００は、図４に示すように、直線状の板材である基端部２１０と、この基端部２１０と連なる弓なりに湾曲した板材である先端部２２０とを有している。基端部２１０は、ベース部１００の保持部１１０の第１の溝部１１１及び第２の溝部１１２にスライド自在に嵌まり込み、スライド移動によりベース部１００の凸部１２０の傾斜面１２１に乗り上げるようになっている。この基端部２１０には、ベース部１００の長孔１１２ａと連通するネジ孔２１１が開設されている。このネジ孔２１１にもネジ３００が挿入される。先端部２２０は、基端部２１０がベース部１００の凸部１２０の傾斜面１２１に乗り上げた状態で、開放された先端の開放端部２２１がベース部１００の当て止め部１３０の傾斜面１３１の上側に位置( 開放位置) するようになっている。この先端部２２０の頂部がランナー２０の上面に付勢接触し、制動部として機能する。先端部２２０は、頂部にランナー２０が付勢接触すると、弾性変形し、これにより開放端部２２１が前記開放位置からベース部１００の当て止め部１３０の傾斜面１３１に当接する当接位置にかけて変位する。なお、開放端部２２１は上方に向けて湾曲している。   As shown in FIG. 4, the leaf spring 200 has a base end portion 210 that is a linear plate material, and a distal end portion 220 that is a plate material curved in a bow shape that is continuous with the base end portion 210. The base end portion 210 is slidably fitted into the first groove portion 111 and the second groove portion 112 of the holding portion 110 of the base portion 100, and is ridden on the inclined surface 121 of the convex portion 120 of the base portion 100 by sliding movement. It has become. The base end portion 210 is provided with a screw hole 211 that communicates with the long hole 112 a of the base portion 100. A screw 300 is also inserted into the screw hole 211. The distal end portion 220 has the base end portion 210 riding on the inclined surface 121 of the convex portion 120 of the base portion 100, and the opened distal end portion 221 of the distal end portion of the inclined surface 131 of the stopper portion 130 of the base portion 100. It is designed to be in the upper position (open position). The top of the tip 220 is urged into contact with the upper surface of the runner 20 and functions as a braking part. The tip 220 is elastically deformed when the runner 20 comes into urging contact with the top, whereby the open end 221 is displaced from the open position to a contact position where it contacts the inclined surface 131 of the stopper part 130 of the base part 100. To do. The open end 221 is curved upward.

このようなブレーキ装置は、図２に示すように、板バネ２００の基端部２１０をベース部１００の保持部１１０に挿入し、板バネ２００の基端部２１０のネジ孔２１１とベース部１００の保持部１１０の第２の溝部１１２の長孔１１２ａの一端部( 図示右側端部) と連通するように位置合わせをする。その後、当該ベース部１００をレール１０の上面に面接触させ、レール１０に設けられた図示しないネジ孔と板バネ２００のネジ孔２１１及びベース部１００の長孔１１２ａにネジ３００とを位置合わせする。そして、板バネ２００のネジ孔２１１、ベース部１００の長孔１１２ａ及びレール１０のネジ孔にネジ３００を挿入し、これによりベース部１００及び板バネ２００をレール１０の上面に取り付ける。   In such a brake device, as shown in FIG. 2, the base end portion 210 of the leaf spring 200 is inserted into the holding portion 110 of the base portion 100, and the screw hole 211 and the base portion 100 of the base end portion 210 of the leaf spring 200 are inserted. Alignment is performed so as to communicate with one end portion (the right end portion in the drawing) of the long hole 112 a of the second groove portion 112 of the holding portion 110. Thereafter, the base portion 100 is brought into surface contact with the upper surface of the rail 10, and the screw 300 is aligned with the screw hole (not shown) provided in the rail 10, the screw hole 211 of the leaf spring 200, and the long hole 112 a of the base portion 100. . Then, the screw 300 is inserted into the screw hole 211 of the leaf spring 200, the long hole 112a of the base portion 100, and the screw hole of the rail 10, and thereby the base portion 100 and the leaf spring 200 are attached to the upper surface of the rail 10.

このとき、ネジ３００を若干緩めておき、ベース部１００の孔部１１１ａに工具を引っ掛け、ベース部１００を図示右方向に移動させる。これにより、ベース部１００上を板バネ２００の基端部２１０が図示左方向にスライド移動し、当該ベース部１００の凸部１２０の傾斜面１２１に乗り上げる。これと共に、板バネ２００の先端部２２０の開放端部２２１が当接位置に変位したときの高さ位置が変わる。その後、板バネ２００の基端部２１０が所望の傾斜角度に達すると、ベース部１００の移動を止める。このように板バネ２００の先端部２２０の頂部の高さ位置を変えると共に、板バネ２００の先端部２２０の開放端部２２１の当接位置の高さ位置を変えることにより、当該板バネ２００の付勢力を調節する。   At this time, the screw 300 is slightly loosened, a tool is hooked in the hole 111a of the base part 100, and the base part 100 is moved rightward in the drawing. As a result, the base end portion 210 of the leaf spring 200 slides in the left direction on the base portion 100 and rides on the inclined surface 121 of the convex portion 120 of the base portion 100. At the same time, the height position when the open end 221 of the tip 220 of the leaf spring 200 is displaced to the contact position changes. Thereafter, when the base end portion 210 of the leaf spring 200 reaches a desired inclination angle, the movement of the base portion 100 is stopped. In this way, by changing the height position of the top portion of the distal end portion 220 of the leaf spring 200 and changing the height position of the contact position of the open end portion 221 of the distal end portion 220 of the leaf spring 200, the leaf spring 200 of the leaf spring 200 is changed. Adjust the biasing force.

その後、ランナー２０がレール１０に案内され、ランナー２０の上面が板バネ２００の先端部２２０の頂部に接触すると、当該ランナー２０の押圧力により板バネ２００の先端部２２０が弾性変形し、この先端部２２０の開放端部２２１が前記開放位置から前記当接位置にかけて変位する。即ち、板バネ２００の先端部２２０の付勢力と、板バネ２００の先端部２２０の開放端部２２１がベース部１００の当て止め部１３０の傾斜面１３１に当接することとによりランナー２０の押圧力による負荷を分散し、これによりランナー２０を制動する。   Thereafter, when the runner 20 is guided by the rail 10 and the upper surface of the runner 20 comes into contact with the top of the tip portion 220 of the leaf spring 200, the tip portion 220 of the leaf spring 200 is elastically deformed by the pressing force of the runner 20, and this tip. The open end 221 of the portion 220 is displaced from the open position to the contact position. That is, the urging force of the front end portion 220 of the leaf spring 200 and the pressing force of the runner 20 by the contact of the open end 221 of the front end portion 220 of the leaf spring 200 with the inclined surface 131 of the stopper portion 130 of the base portion 100. The load due to is distributed, thereby braking the runner 20.

このようなブレーキ装置による場合、板バネ２００の基端部２１０がスライド移動することによりベース部１００の凸部１２０の傾斜面１２０に乗り上げ、これにより当該板バネ２００の先端部２２０の頂部の高さ位置を大きく変えることができるようになっている。このため、高さ寸法の高いレールにも対向することが可能になる。しかも、ランナー２０の押圧力による負荷を、板バネ２００の先端部２２０の付勢力と、板バネ２００の先端部２２０の開放端部２２１をベース部１００の当て止め部１３０に当接させることとにより、分散させる構成となっているので、従来例のような板バネ２００の付勢力のみでランナー２０を制動するブレーキ装置と比べて長寿命化を図ることができる。   In the case of such a brake device, the base end portion 210 of the leaf spring 200 slides and rides on the inclined surface 120 of the convex portion 120 of the base portion 100, thereby increasing the height of the top portion of the distal end portion 220 of the leaf spring 200. The position can be changed greatly. For this reason, it is possible to face a rail having a high height. In addition, the load caused by the pressing force of the runner 20 is caused to abut the urging force of the distal end portion 220 of the leaf spring 200 and the open end portion 221 of the distal end portion 220 of the leaf spring 200 against the stopper portion 130 of the base portion 100. Therefore, the life can be extended as compared with a brake device that brakes the runner 20 only by the urging force of the leaf spring 200 as in the conventional example.

なお、ブレーキ装置については、レールに取り付けられ、このレールに案内されるランナーを制動するブレーキ装置であって、レールに取り付けられるベース部と、基端部が前記ベース部にスライド移動可能に取り付けられた板バネとを備えており、前記板バネの先端部は、先端が開放され、弓なりに湾曲した板体であって、その頂部がランナーに付勢接触することによりランナーを制動するようになっており、前記ベース部には、前記板バネの基端部の移動路上に位置し、当該基端部がスライド移動することにより乗り上げ可能な凸部と、付勢接触により変位した前記板バネの先端部の開放端部が当接可能な当て止め部とが設けられている限りどのような設計変更を行ってもかまわない。   The brake device is a brake device that is attached to a rail and brakes a runner guided by the rail, and a base portion attached to the rail and a base end portion are slidably attached to the base portion. A leaf spring, and the tip of the leaf spring is a plate body that is open at the tip and curved like a bow, and the top of the leaf spring biases and contacts the runner to brake the runner. The base portion is located on the movement path of the base end portion of the leaf spring, and can be lifted by sliding the base end portion, and the leaf spring displaced by the urging contact. Any design change may be made as long as the contact stop portion with which the open end portion of the tip portion can contact is provided.

即ち、凸部１２０については、板バネ２００の基端部２１０がスライド移動することにより乗り上げ可能な凸部であれば良く、傾斜面１２１を設けるか否かは任意である。例えば、図５に示すように、円弧状の凸部等を設けることが可能である。   That is, the convex portion 120 may be a convex portion that can be ridden by sliding the proximal end portion 210 of the leaf spring 200, and whether or not the inclined surface 121 is provided is arbitrary. For example, as shown in FIG. 5, it is possible to provide an arcuate convex portion or the like.

同様に、当て止め部１３０についても、付勢接触により変位した板バネ２００の先端部２２０の開放端部２２１が当接可能な凸部であれば良く、傾斜面１３１を設けるか否かは任意である。   Similarly, the abutting stopper 130 may be a convex portion that can contact the open end 221 of the distal end portion 220 of the leaf spring 200 displaced by the biasing contact, and whether or not the inclined surface 131 is provided is arbitrary. It is.

板バネ２００については、先端部２２０の開放端部２２１が上方にむけて湾曲しているとしたが、先端部２２０が弓なりに湾曲していれば良い。   Regarding the leaf spring 200, the open end 221 of the tip 220 is curved upward, but it is only necessary that the tip 220 is curved like a bow.
