Abstract

(57) [Abstract] [Problem] To brake a bicycle, a user pulls a brake lever with a finger. This operation makes it difficult for an infant to grasp the grip firmly during braking, and if the brake lever does not reach the finger sufficiently, the braking operation may be delayed or sufficient braking force may not be obtained and it may hit the object or human body. There was a problem, and if the play adjustment of the brake lever was too large, a finger could be caught between the brake lever and the grip. In view of these problems, a braking operation device that is easy to operate was sought. In order to solve the above-mentioned problems, a braking operation device according to the present invention has a structure in which a gripping shaft supporting a handlebar is slidably rotated through a bracket, and a base part of the gripping gear 1 is provided. The engaging element 8 of the brake wire hooked in the hooking hole 6 provided in a certain flange 3 is pulled and the brake wire wound up and connected to the guide groove 7 is operated.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a braking operation device for a bar handle, and more particularly to a braking operation device for a vehicle such as a bicycle.

[0002]

[Prior art]

 Conventionally, in a vehicle that has a bar handle, the bicycle is operated by fixing the grip to the handlebar and operating the brake lever pivotally supported by the handle fixing bracket via the bracket from the return position to the forward position. It is known that the brake wire is operated to activate the brake.

[0003]

[Problems to be solved by the invention]

 In the conventional technique, the brake operation is performed by pulling the brake lever with a finger and braking. This operation makes it difficult for small children and infants to grasp the grip firmly, and if the brake lever is not sufficiently reached by the finger, the braking operation will be delayed or the braking force will be insufficient, causing a dangerous problem of hitting an object or human body. was there. Also, if the brake lever had too much play adjustment, when pulling the brake lever, a finger could be caught between the brake and the brake lever.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to perform a brake operation and a steering wheel operation while constantly gripping a grip, and to operate a bicycle or the like. Riding the vehicle more safely.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the braking operation device according to the present invention operates the brake wire 9 by rotating the grip 1 having the handlebar H supported by the brackets 10 and 11 and rotating the grip 1 in the counterclockwise direction. This is a braking operation device configured to actuate a brake. The nigiri 1 has a flange 4 and a return positioning projection 5 on a base 4, and a hook for locking a cylindrical engaging element 8 of a brake wire on the flange 3. A guide groove 7 for winding up the brake wire 9 connected to the stop hole 6 and the engaging element 8 is provided, and the flange base 4 further has a winding spring 19 for biasing the gripper 1 to the return position with respect to the brackets 10 and 11. It has a structure that is equipped with.

The bracket can be divided into an upper portion 10 and a lower receiving portion 11, and has a U-shaped groove 12 or 14 on which the flange 3 and the return positioning protrusion 5 are slidably rotated. However, since the groove 14 for the return positioning projection 5 to rotate is provided only on the inner surface of the bracket lower receiving portion 11, it slides and rotates within the range of the bracket lower receiving portion to regulate the return position of the grip 1. To do. Further, in the groove 14 in which the flange 3 of the bracket lower receiving portion 11 and the return position determining projection (5) rotate, there is a wire insertion hole 16 for leading out the brake wire 9 to the outside, and the lumen portions 13, 15 are , And serves as a spring chamber into which a winding spring 19 for urging the grip 1 toward the return position is inserted. The brackets 10 and 11 are fixed to the handlebar H by tightening the tightening bolts 17 and 18 so that the upper part and the lower support part are aligned with each other, and the bracket 3 supports the grip 1 and the flange 3 winds the brake wire 9. Raise it and activate the connected brake.

[0007]

[Embodiment]

 In the figure, 10 and 11 are brackets that are fixed to the handlebar H, and 1 is a grip that is axially supported by the handlebar H. The flange 3 at the base of the grip 1 has a hooking hole 6 for locking the cylindrical engaging element 8 of the brake wire and a guide groove 7 for winding up the brake wire 9 connected to the engaging element 8. Further, a part of the flange 3 has a return positioning projection 5 protruding in the axial direction, and a winding spring 19 for biasing the brackets 10 and 11 to the return position is attached to the gripping base 4. A spring foot 23 extending in the direction of the center line from the end of the winding portion is hooked in a locking hole 21 in the return positioning projection 5, and a spring foot 2 extending in the direction of the center line from the end of the other winding portion. 2 is hooked in the hooking hole 20 in the bracket lower receiving portion 11, and the grip 1 is returned from the operating position to the return position. The cover body 24 that covers the grip portion 2 of the grip 1 is made of a material such as rubber that is hard to slip and has a good tactile sensation.

The bracket has an upper portion 10 and a lower receiving portion 11 which are divided into U-shaped grooves 12 and 14 on which the flange 3 and the return positioning protrusion 5 slide and rotate. The groove 14 for sliding rotation of 5 is provided only on the inner surface of the bracket lower receiving portion 11. This limits and regulates the range in which the return positioning protrusion 5 slides and rotates within the bracket lower receiving portion. Further, the groove 14 has a wire insertion hole 16 for guiding the brake wire 9 to the outside of the bracket lower receiving portion 11, and the inner cavity portion 15 is provided with a retaining hole 20 for retaining the spring foot 22 of the coil spring 19. ing. The brackets 10 and 11 are fastened to the handlebars H by fastening the tightening bolts 17 and 18 so that the upper portion and the lower receiving portion are aligned with each other and support the grip.

The present invention is configured as described above, and the non-braking 1 is in the returning position direction by the winding spring 19 during the non-braking operation. When the brake 1 is turned counterclockwise during braking operation, the brake wire engaging element 8 hooked in the hooking hole 6 of the flange 3 is pulled, the brake wire 9 is wound up in the guide groove 7, and the brake wire insertion hole is inserted. The brake wire 9 led out to the outside of the bracket through 16 activates the connected brake. Since the bicycle has braking operation devices on the left and right of the steering wheel, the operation on the right side must be turned clockwise.

[0010]

[Effect of the invention]

 Since the braking operation device for the bar handle according to the present invention is configured as described above, it has the following effects.

Since the brake is operated by rotating the grip, the brake lever used in the past becomes unnecessary and when the play adjustment of the brake lever is too large, a finger is caught between the brake lever and the grip. Things will disappear.

[0012] The handle portion is neat and the design is beautiful. The braking operation is performed while holding the grip just as when the vehicle is not braking, so that the steering wheel operation is stable and the immediate braking operation can be performed in an emergency.

In addition to the above effects, the safety of work etc. can be achieved by operating the handlebars of tricycles for infants, construction and agricultural unicycles, and the brakes attached to and connected to the handle parts of strollers, shopping carts, etc. To help.
