no. 1 Embodiment approach

[0064] exist figure 1 Among them, a bicycle 1 on which an embodiment of the present invention is mounted includes a frame 2 having a front suspension fork 3 and a handlebar 4 fixed to an upper portion of the front suspension fork 3 . A front derailleur 17 constituting an external transmission is attached to the middle portion of the body frame 2 , and a rear derailleur 18 is attached to the rear end portion of the body frame 2 . The front derailleur 17 is arranged, for example, at the lower portion of the seat tube 2b of the body frame 2, and guides the chain 23 to, for example, any sprocket of the front gear 19a having three sprockets. The rear derailleur 18 is arranged on the rear end portion of the chain stay 2c of the body frame 2, and guides the chain 23 to, for example, one of the sprockets of the rear gear 19b having nine sprockets. The front derailleur 17 and the rear derailleur 18 are connected to front and rear shift operation parts (an example of a shift operation ...

no. 2 Embodiment approach

[0091] In the above-mentioned first embodiment, the position holding / release mechanism 34 moves in a direction perpendicular to the plane in which the winding body 32 rotates, but in the second embodiment, as Figure 11 As shown, in the rear shifting operation unit 116 , the position holding / release mechanism 134 moves along a plane ( P1 ) parallel to the plane in which the winding body 132 rotates.

[0092] The rear shift operating part 116 has a figure 2 Mounting portion 30 is shown in the same shape as mounting portion 130 . In addition, the rear shifting operation part 116 such as Figure 11 As shown, it has: a support shaft 131, which is connected to the mounting part 130, and extends along the direction of the first axis cable X1; direction and the cable release direction to move around the first axis cable X1 rotatably installed; the position holding · release mechanism 134 selectively holds the winding body 132 in a plurality of holding positions corresponding to a ...

no. 3 Embodiment approach

[0127] In the above-mentioned second embodiment, an input member that is oscillated by the two oscillating shafts 165 and 166 in a plane parallel to the first plane (P) was exemplified, but a joystick-shaped input member may also be used.

[0128] Mounting part 230 such as Figure 22 to Figure 2 6, it has a bracket 240 that can be installed on the handlebar 4 by fastening bolts, such as a metal plate, a first cover 242 installed on one side of the bracket 240, and the other side of the bracket 240. The second cover part 244 on the side. The bracket 240 has a flat surface 240a on which the wound body 232 is arranged, and an opening 240b to which a rotation shaft 246 is non-rotatably attached. The rotation shaft 246 extends upward through the opening 240 b of the bracket 240 . The tip of the rotating shaft 246 is fixed by a fixing bolt 241 to fix the second operating member 238 . In addition, a female thread portion 240c is formed on the bracket 240, and a housing 26b ( Fig...

Abstract

There is provided a shift operation device for a bicycle having an operation member that can suit an operation direction of the operation member to rider's preference. A rear shift operation portion (16) includes a mounting portion (30) mountable to the bicycle; a winding body (32); a position holding and releasing mechanism (34); and a releasing lever (36). The winding body is mounted to the mounting portion movably in a cable pulling direction and a cable releasing direction. The position holding and releasing mechanism selectively holds the cable lock body in any one of a plurality of holding positions. The releasing lever is a member that is mounted to the mounting portion movably in a first direction and a second direction, and operates the position holding and releasing mechanism in response to the movement in the first direction and the second direction to move the cable lock body in the cable releasing direction, respectively.

Description

technical field [0001] The present invention relates to a shift operating device, and more particularly to a bicycle shift operating device mounted on a bicycle frame for performing a shift operation of any one of a plurality of shift positions of a shift device connected by a shift cable. Background technique [0002] Some bicycles are equipped with a transmission such as a built-in transmission or an external transmission. In order to perform the shifting operation of these shifting devices, a shifting operation device connected to the shifting device via a shifting cable is used. As a conventional speed change operation device, there is known an operation member type speed change device having a wind-up operation member in the shape of an operation member that swings and a release operation member. In the operating member-type shift operating device, there are known technologies for swinging and operating the winding operating member and the release operating member in t...
