発明の詳細な説明Detailed Description of the Invention

産業上の利用分野Industrial application fields

本発明は、例えば、本発明者が考案し出願した意願２００８−１８３３６号に係る、自転車に取り付けて使用することが好ましいクラッチ機構に関するものである。  The present invention relates to a clutch mechanism which is preferably attached to a bicycle and used, for example, according to the application 2008-18336 devised and applied by the present inventor.

クラッチは比較的大型の装置に使用されるものであって、自転車のような比較的小型の装置には使用された例は知らない。自転車は大重量の物を運ぶものではなかったことも、「クラッチ不使用」と云うことの一原因であろう。
本発明者の前記意願２００８−１８３３６号に係る自転車は、その願書中の〔意匠に係る物品の説明〕に記載の通り「小荷物や商品配送などのための三輪自転車」で比較的大重量の物を運ぶものであって、クラッチを使用することが好ましいとせられるのである。The clutch is used for a relatively large device, and there is no known example used for a relatively small device such as a bicycle. The fact that bicycles did not carry heavy objects would also be a cause of "no clutch".
The bicycle according to the present application 2008-18336 of the present inventor is a “three-wheel bicycle for small parcels or goods delivery” as described in [Description of articles related to design] in the application, and is relatively heavy. It is intended to carry things and to use a clutch.

依って、本発明者は下記の本発明をしたのである。
記
一方の軸（７）に取付けられた一方のディスク（１）と、他方の軸（８）に取付けられた他方のディスク（２）とがあり、前記一方のディスク（１）の周辺部には複数個の係合突子（９）を設け、該係合突子（９）に係合する係合受部（６）が前記他方のディスク（２）に設けられると共に、前記一方の軸（７）の端部はその軸芯部分は中空にし、この中空の部分に、前記他方のディスク（２）の中心から前記一方のディスク（１）の中心部分を貫通して突設された係合桿（５）を遊嵌し、且つ該係合桿から突設の係合子（４）を案内する案内孔（１０）を、前記一方のディスク（１）から前記一方の軸（７）を包むように突設した管体（１１）に設けるに当り、前記一方の軸（７）が回転し始めた時に、係合子（４）が斜め方向に案内方向に案内することで（図１の状態から図２の状態になる、即ち）前記他方のディスク（２）が、前記一方のディスク（１）の方に移動し、両者を密着せしめるようにしたクラッチ機構
而して、該クラッチ装置を装備する三輪自転車には、図１に図示の通り、バッテリ（１２）、モータ（１３）を駆動補助器として設置する。Therefore, the present inventor has made the present invention described below.
There is one disk (1) attached to one shaft (7) and the other disk (2) attached to the other shaft (8), in the periphery of the one disk (1) Is provided with a plurality of engagement protrusions (9), and an engagement receiving portion (6) for engaging with the engagement protrusions (9) is provided on the other disk (2), and the one shaft The end portion of (7) has a hollow shaft core portion, and the hollow portion projects from the center of the other disc (2) through the central portion of the one disc (1). A guide hole (10) for loosely fitting the fitting (5) and guiding the engaging member (4) protruding from the engaging rod, and the one shaft (7) from the one disk (1). When the one of the shafts (7) starts to rotate when the tube (11) is provided so as to project, the engaging element (4) is guided obliquely. By guiding in the direction (from the state of FIG. 1 to the state of FIG. 2), the other disk (2) is moved toward the one disk (1) and brought into close contact with each other. Clutch mechanism Thus, a three-wheeled bicycle equipped with the clutch device is provided with a battery (12) and a motor (13) as drive aids as shown in FIG.

作用Action

上記のような構成によれば、クラッチとしての作動が適確で、この適確性は、前記一方の軸（７）に相当に大きな応力が加えられると軽減することはなく、しかも比較的に軽量であって、自転車の駆動部分に使用されるのに適切である。而して、バッテリ（１２）、モータ（１３）は、実用上、極めて有用である。  According to the configuration as described above, the operation as a clutch is accurate, and this accuracy is not reduced when a considerably large stress is applied to the one shaft (7), and is relatively lightweight. And is suitable for use in the driving part of a bicycle. Thus, the battery (12) and the motor (13) are extremely useful in practice.

以下、本発明の一実施例について図面を参照して説明する。
図１は、一方のディスク１と、他方のディスク２とが離れている状態での斜面図であり、図２は２個のディスク１，２が密着している状態での斜面図である。図３は駆動関係を図示した線図である。An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a slope view in a state where one disk 1 and the other disk 2 are separated from each other, and FIG. 2 is a slope view in a state where two disks 1 and 2 are in close contact with each other. FIG. 3 is a diagram illustrating the driving relationship.

図中、３は本発明のクラッチを使用する自転車であって、実施例として本発明者の出願に係る意願２００８−１８３３６号の意匠に係る自転車が例示される。７は、前記一方のディスク１に取り付けられた入力軸（一方の軸）であって、該一方の軸７の端部はその軸芯部分は中空にし、この中空の部分に、前記他方のディスク２の中心から前記一方のディスク１の中心部分の空洞を貫通して突設された係合桿（図示せず）を遊嵌する。４は該係合桿から突設された係合子であって、該係合子４を案内する案内孔１０を、前記一方のディスク１から前記一方の軸７を包むように突設した管体１１に設けるに当り、前記一方の軸７が回転し始めた時に係合子４が斜め方向に案内方向に案内されることで、前記他方のディスク２が、前記一方のディスク１の方に移転し、両者を密着せしめるようにする。  In the figure, reference numeral 3 denotes a bicycle using the clutch of the present invention. As an example, a bicycle according to the design of Japanese Patent Application No. 2008-18336 according to the present inventor's application is illustrated. Reference numeral 7 denotes an input shaft (one shaft) attached to the one disk 1, and the end of the one shaft 7 is hollow at the shaft core portion, and the other disk is connected to the hollow portion. An engagement rod (not shown) protruding from the center of 2 through the cavity of the central portion of the one disk 1 is loosely fitted. Reference numeral 4 denotes an engaging member projecting from the engaging rod, and a guide hole 10 for guiding the engaging member 4 is provided on a tubular body 11 projecting from the one disk 1 so as to wrap the one shaft 7. In providing, when the one shaft 7 starts to rotate, the engaging element 4 is guided obliquely in the guiding direction, so that the other disk 2 moves toward the one disk 1 and both Make sure they are in close contact.
