The operating mechanism includes a bicycle parking lever and a main body portion, and the main body portion is attached with the parking bicycle lever, and one end of the main body portion is located on the outer side, and the through-hole is inside the main body portion. Is fitted into the brake lever for braking located at the other end of the main body.

  The bicycle lever operating structure of the present invention includes a general braking brake lever and a parking lever operating mechanism that can be retrofitted to the braking brake lever. That is, the bicycle lever operating structure is configured by retrofitting the parking lever operating mechanism to the braking brake lever.

  In a general brake brake lever, an inner extending from the outer is attached to the brake brake lever with respect to the outer fixed at the same position, and when the brake lever is pulled, the inner The brakes are relatively separated from each other, thereby actuating the brake for braking.

  On the other hand, the bicycle parking lever operating mechanism constituting the bicycle lever operating structure of the present invention includes a brake lever for braking and a parking lever operating mechanism. Lever and main body. A bicycle parking lever is attached to the main body, and one end of the main body is positioned on the outer side, and a brake brake lever is positioned on the other end of the main body through the through hole in the main body. It can be fitted.

  By adopting such a configuration, a bicycle parking lever operating mechanism is retrofitted to the braking brake lever to form a bicycle lever operating structure, so that the braking brake can be operated by pulling the braking brake lever. Can be guaranteed.

  Therefore, when a bicycle parking lever operating mechanism is attached to the brake brake lever as a retrofit, the normal brake brake can be operated by pulling the brake brake lever while driving a bicycle such as a tricycle. When parking the bicycle, the bicycle can be parked without using the stand by pulling the parking lever and moving the outer. In this way, the parking lever operating mechanism has a role as a parking brake.

  In addition, according to the bicycle lever operating structure of the present invention, the parking brake and the braking brake can be integrated into one mechanism without using separate mechanisms.

  Further, in the bicycle lever operating structure of the present invention, the parking lever and the braking brake are integrated into one mechanism as described above, but the parking lever is not affected without affecting the braking during traveling. It becomes possible to operate.

  Furthermore, since the parking lever is a detachable and simple mechanism, productivity and safety are improved.

  Here, as an embodiment of the bicycle lever operating structure, the main body portion is composed of a first main body portion and a second main body portion. The second main body portion is movable relative to the first main body portion, and the outer mounting portion is disposed at one end thereof. The form currently provided can be mentioned.

  Here, “the second main body portion is movable relative to the first main body portion” means that the second main body portion moves relative to the first main body portion when the parking lever is pulled. It means that it is possible to move in the longitudinal direction (direction in which the inner penetrates). According to this embodiment, the lever can be operated with a simple mechanism.

  In the embodiment of the bicycle lever operating structure according to the present invention, the bicycle parking lever operating mechanism includes a link piece that is slidable with respect to the first and second body parts, The link piece constitutes a toggle link mechanism. Here, “the link piece is slidable with respect to the first and second body parts” means that the link piece is first when the ring nut described later is rotated or when the parking lever is pulled. This means that the main body and the second main body can be moved in the longitudinal direction of the main body.

  Furthermore, in the embodiment of the bicycle lever operating structure according to the present invention, the parking lever operating mechanism further includes an adjuster and a ring nut, and the adjuster is attached to the link piece, and the first piece together with the link piece. The ring nut is slidable with respect to the first and second body parts together with the adjuster. Here, “the adjuster is slidable together with the link piece with respect to the first and second main body portions” means that when the ring nut is rotated, the adjuster moves between the first main body portion and the second main body portion. This means that it can move in the longitudinal direction, and it means that when the parking lever is pulled, the adjuster can move in the longitudinal direction with respect to the first main body. Furthermore, “the ring nut is slidable with respect to the first and second body parts together with the adjuster” means that when the ring nut is rotated, the ring nuts This means that the ring nut can be moved in the longitudinal direction, and the ring nut can be moved in the longitudinal direction with respect to the first main body when the parking lever is pulled.

  Further, the present invention extends to a bicycle, and this bicycle includes the bicycle lever operating structure.

  According to the bicycle of the present invention, the operation of both the brake for braking and the parking brake can be guaranteed by the bicycle lever operating structure having a simple structure in which the parking brake and the brake for braking are integrated into one mechanism. .

  As can be understood from the above description, according to the bicycle lever operating structure of the present invention, the parking lever operating mechanism can be attached later to a general braking brake lever. In the state where the lever operation mechanism is retrofitted and the bicycle lever operation structure is configured, both the operation of the brake for braking and the operation of the parking brake can be guaranteed.

It is a longitudinal cross-sectional view of the lever operation structure for bicycles in the state of FIG. It is an external appearance perspective view of the lever operation structure for bicycles in the state which pulled the lever (state in which the lever operation mechanism for parking) is operating. It is a longitudinal cross-sectional view of the lever operation structure for bicycles in the state of FIG.

  Embodiments of a bicycle lever operating structure according to the present invention will be described below with reference to the drawings.

(Embodiment of bicycle lever operating structure)
FIG. 1 is an external perspective view of a bicycle lever operating structure according to the present invention, showing a state before the lever is pulled (a state where the parking lever operating mechanism is not in operation), and FIG. It is a longitudinal cross-sectional view of the lever operation structure for bicycles in the state of FIG. 3 is an external perspective view of the bicycle lever operation structure in a state where the lever is pulled (a state where the bicycle parking lever operation mechanism is activated), and FIG. 4 is a bicycle lever operation in the state of FIG. It is a longitudinal cross-sectional view of a structure.

  The illustrated bicycle lever operating structure 100 includes a braking brake lever 20 and a parking lever operating mechanism 10 attached to a handle HN of a bicycle such as a tricycle, and the parking lever operating mechanism 10 includes a braking lever. This is a mechanism that can be assembled later between the brake lever 20 for braking and the brake wire W for braking.

  More specifically, the brake wire W is removed from the brake lever 20 for braking, the inner W1 is inserted into the parking lever operation mechanism 10, and the outer W2 of the brake wire W is attached to the parking lever operation mechanism 10. By attaching to the end, the assembly of the parking lever operating mechanism 10 is completed, and the bicycle lever operating structure 100 including the braking brake lever 20 and the parking lever operating mechanism 10 is formed.

  The parking lever operating mechanism 10 includes a first main body 1 having a through hole 1a, a second main body 2 having a through hole 2a assembled so as to partially overlap the first main body 1, and a lever. 6 and a toggle link mechanism 8 in which a link piece 7 is rotatably assembled by a rotation shaft 6a.

  1 and 2, an inner attachment location 20 a is provided at the end of the braking brake lever 20 on the first body portion 1 side, and an outer attachment location 2 c is provided at the end of the second body portion 2.

  A ring nut 3 having a hollow 3 a and an adjuster 4 having a hollow 4 a are disposed around the second main body 2, and a thread groove 3 b provided on the inner periphery of the ring nut 3 is provided on the second main body 2. It is screwed into a screw groove 2b provided around.

  The adjuster 4 is in slidable contact with the periphery of the second main body 2, and when the ring nut 3 is rotated (Z direction), the adjuster 4 does not rotate and moves along the screw groove 2 b of the second main body 2. The adjuster 4 also moves along the axial direction of the second main body 2 in accordance with the movement of the ring nut 3 (Y direction).

  In addition, a frictional force between the inner peripheral surface of the ring nut 3 and the outer peripheral surface of the adjuster 4 to block the clearance between them (suppressing the ring nut 3) The friction generating member 5 is interposed in order to generate a degree of pinching. As the friction generating member 5, a resin plate, a rubber plate, or the like can be applied. Here, the retaining member 9 is fitted to the ring nut 3 at a position adjacent to the friction generating member 5. The retaining member 9 prevents the adjuster 4 and the friction generating member 5 from coming off. That is, when the ring nut 3 moves in the Y direction in FIG. 2, the adjuster 4 can follow the movement of the ring nut 3 and move integrally with the ring nut 3 in the Y direction.

  As shown in FIGS. 1 and 2, the parking lever 6 is rotatably attached to the first main body 1 via a rotation shaft 6 b, and the rotation shaft 7 a at the end of the link piece 7 is an adjuster. 4 and the long hole 2d of the second body 2 are rotatably fitted, and the link piece 7 and the adjuster 4 are connected via the rotating shaft 7a. Further, the adjuster 4 and the second main body 2 are connected via a ring nut 3, and the link piece 7, the rotating shaft 7 a, the adjuster 4, the ring nut 3, and the second main body 2 are connected in this order. .

  As shown in FIGS. 1 and 2, when the ring nut 3 is manually rotated around the second main body 2 (Z direction), the ring nut 3 and the adjuster 4 move relative to the second main body 2 (Y The relative position in the Y direction between the rotary shaft 7a of the toggle link mechanism 8 and the second body portion 2 can be adjusted within the range of the long hole 2d of the second body portion 2.

  When the ring nut 3 is rotated and the adjuster 4 is relatively moved in the direction approaching the parking lever 6, the rotating shaft 7a approaches the rotating shaft 6b, and as a result, the rotating shaft 6a is lifted upward. As a result, the parking lever 6 stands in a state where the tilt angle is increased with respect to the first main body 1. This state is referred to as state G.

  On the other hand, when the ring nut 3 is rotated in the opposite direction to the above and the adjuster 4 is relatively moved away from the parking lever 6, the rotating shaft 6 a is lowered this time. It will be in the state which fell to the 1st main-body part 1, reducing an inclination angle. This state is referred to as state H.

  As shown in FIGS. 3 and 4, by pulling the parking lever 6 (in the X1 ′ direction) to operate the parking lever operating mechanism 10 such as a tricycle at the time of stopping and park the vehicle, the rotating shaft 6a. The link piece 7 is rotated around the center (X2 ′ direction), the outer mounting portion 2c is pushed out (Y ′ direction), and the distance L2 between the inner mounting portion 20a and the outer mounting portion 2c is longer than the distance L1. It becomes.

  That is, by pulling the parking lever 6, the inner W1 can be pulled with respect to the outer W2 without operating the brake lever 20, so that it is the same as when the brake lever 20 is pulled. In addition, a braking force can be generated by a brake (not shown).

  In the state G described above, since the stroke amount of the toggle link mechanism 8 is large, the difference between L1 and L2 is large.

  On the other hand, in the state H described above, since the stroke amount of the toggle link mechanism 8 is small, the difference between L1 and L2 is smaller than that in the state G.

  Therefore, between the state G and the state H, the braking force during parking can be adjusted independently of the braking force during traveling.

  On the other hand, since the friction generating member 5 is interposed between the adjuster 4 and the ring nut 3, it is possible to position the ring nut 3 at an arbitrary position, for example, vibration during operation of a tricycle or the like. Therefore, it is possible to suppress the ring nut 3 from freely (naturally) rotating.

  In the illustrated parking lever operating mechanism 10, the toggle link mechanism 8 is applied as a mechanism for moving the outer attachment location 2 c, so that the parking lever operating mechanism 10 can be operated with as little gripping force as possible. Can be executed. In addition to this, by adjusting the stroke by the ring nut 3 as described above, it is possible to adjust the braking force of the parking lever operating mechanism 10 at an arbitrary strength.

  In addition, since the parking lever operating mechanism 10 can be easily installed later on the brake lever W attached to the brake lever 20 having a general structure, the parking lever operating mechanism 10 can be installed. Can respond to requests for retrofit.

  Since the operation of the parking lever operation mechanism, which is a parking brake, is realized in a state where the parking lever operation mechanism 10 is attached, the operation of the braking brake during normal operation and the parking operation are performed. The operation of the bicycle parking lever operating mechanism 10 can be ensured together.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
