Definitions

• the present invention relates to a brake caliper that is driven by a brake wire and presses a brake shoe against a rim side of a wheel.
• Bicycles often have mounting holes for attaching brake calipers or mudguards to front forks, seat stays or chain stays.
• a pair of left and right shaft pins for mounting the brake caliper may be provided on the seat stay or chain stay on the front fork fork leg.
• the bending radius of the brake wire is greatly increased. It is desirable that wiring be performed so that the total bending angle is small.
• the brake wire connected to the brake arm will not cause the brake arm's left / right balance to be disrupted by the force acting in the way of the brake arm's movement, and the brake wire will not be dragged on one side. Loose wiring is desirable. '
• the carbon fiber is sufficiently light and highly elastic.
• Fork legs, seat stays, or chain stays made of steel, etc. a large amount of reinforcement is required to catch the strong force applied to the fulcrum, reducing the weight and shock absorption of the front forks, seat stays, or chain stays. Will be sacrificed.
• the fork legs and seat stays that are open laterally from the rim side If the fulcrum of the brake arm is placed on the chain or chain stay, the force that pushes and pulls the rim size toward the outer circumference of the wheel is distributed during one press of the brake shoe, and the brake shoe that is directly related to the braking force is The force that pushes the door vertically decreases.
• a bicycle brake caliper is a braking device for braking a bicycle, as shown in FIGS. 1 and 2, a pair of left and right central axes 16 comprising a first central axis and a second central axis. And has a base member 10 that can be firmly attached to a mounting hole centered on the central axis 12.
• the first central axis and the second central axis are set in the direction perpendicular to a plane including all of the rim side 15 to which one of the pair of left and right brake shoes 6 is pressed.
• the first plane line and the second plane line projected onto the plane are within the range of plus or minus 45 degrees perpendicular to the center axis line 12 of the mounting hole.
• the pair of left and right brake arms 8 is extended along the tire 3 with the pair of left and right central axes 16 as the fulcrum in the lever so that the front ends of the pair of left and right brake arms 8 act as a force point in the lever. Connect the brake outer 1 to one of the front ends of the left and right brake arms 8, and fix the brake inner 4 to the other.
• the pair of left and right brake shoes 6 are fixed to the inside of the pair of left and right brake arms 8, and the brake lever 19 installed on the handlebar 18 is gripped as shown in Fig. 3.
• the inner wire 4 is pulled, and the pair of left and right brake shoes 6 are pressed against the rim side 15 to brake the bicycle.
• the pair of left and right brake shoes 6 are separated from the rim side 15 by the panel member 7 that works in the direction in which the front ends of the pair of left and right brake arms 8 open.
• the bicycle brake caliper according to the more specific plan 1 is the bicycle brake caliper X of the invention 1.
• the bicycle brake caliper X has a pair of left and right shaft pins 9 centered on the first central axis and the second central axis, respectively.
• the base member 10 is fixedly installed, and a pair of left and right shaft pins 9 respectively rotatably supports the rear end portions of the pair of left and right brake arms 8.
• the bicycle brake caliper according to the plan 2 is the same as the bicycle brake caliper described in 1), in which the first central axis and the second central axis are concentric axes, and these axes are the center.
• the third shaft pin is fixedly installed on the base base member 10, and the third shaft pin rotatably supports the rear end portions of the pair of left and right brake arms 8.
• the bicycle brake caliper according to the plan 3 is based on the pair of left and right shaft pins 9 centered on the first central axis and the second central axis in the bicycle brake caliper of the invention 1, respectively.
• the pair of left and right shaft pins 9 are fixedly installed at the rear end portions of the pair of left and right brake arms 8, respectively.
• the bicycle brake carrier according to the plan 4 is a bicycle brake carrier according to any one of the invention 1 and the plan 1 to the plan 3, wherein the front end portions of the brake outer 1 and the pair of left and right brake arms 8 are provided.
• a connecting member 2 rotatably attached to one of the front end portions of the pair of left and right brake arms 8 is used.
• the brake wire 1 composed of the brake outer 1 and the brake inner 4 is compared without arranging the fulcrum portion of the lever on the fork leg 11, the seat stay 20 or the chain stay 21.
• a large bending radius it is possible to wire smoothly without increasing the total bending angle.
• the pair of left and right shaft pins 9 can be combined into one, so that the cost can be reduced as the structure is simplified.
• the connecting member 2 works so as to alleviate the influence of the brake outer 1 that is affected by the movement of the handlebar 1 8, so the left-right balance of the pair of left and right brake arms 8 is It's hard to be affected by the disturbance caused by 1.
• Example 1 mounted for front wheel braking
• the base member 10 is cut by aluminum forging, then embedded and embedded port 1 Oa is embedded, and an embedded bolt 1 Oa is inserted into the mounting hole of the front fork 1 7 is fixed.
