Description

  In the present invention, the base of the brake lever is pivotally supported on a base that is fixed to the vehicle body, the tip of the brake lever is extended to the vicinity of the operator, a force is applied to the tip, and the brake follows the swing of the brake lever. The present invention relates to a manual brake device that applies a brake by pulling a cable.

  For example, in a manual brake device such as a foot-operated parking brake, the base of the brake lever is pivotally supported on a base that is fixed to the vehicle body, and its tip extends to the vicinity of the operator. It is known that the brake cable is pushed and pulled in accordance with the swing of the brake lever to apply the braking.

  As such a conventional manual brake device, there is one as shown in Patent Document 1.

  That is, the patent document discloses an internal-tooth ratchet type locking mechanism that holds the braking state when the brake lever is depressed and released from the non-braking state, and then releases the braking holding state when the brake lever is depressed again. And a technique using a sliding plate for releasing this is disclosed.

JP-A-7-186909

[3] The manual brake device (1) according to [1] or [2], wherein the brake lever (20) applies a force by stepping on the tip (23) with a foot.

The present invention operates as follows.
When a force is applied to the distal end portion (23) of the brake lever (20) in which the base portion (21) is pivotally supported by the base (10) fixed to the vehicle body, the brake lever ( When the output link member (30) swings in one direction from the non-braking position by being pushed by the base (21) of 20), the connected brake cable (C) can be pulled to generate a braking force.

  That is, when a force is applied to the tip (23) of the brake lever (20), the force is transmitted from the base (21) of the brake lever (20) to the output link member (30) at the end of the switching play (S). It is rotated and the brake cable (C) is pulled.

  When the output link member (30) is rotated, the pawl member pivotally supported by the output link member (30) while meshing with the teeth (12a) of the ratchet plate (12) fixed to the base (10). (40) moves. When a moderate braking force is obtained, when the force of the tip (23) of the brake lever (20) is released and released, the claw member (40) meshes with the tooth (12a) at that position and the output link member. (30) is prevented from returning and the braking state is maintained.

  The engagement / disengagement switching member (50) is pivotally attached to the output link member (30) so as to be able to swing between a braking position and a release position, and when applying force to the distal end portion (23) of the brake lever (20). It is in the braking position. When the brake lever (20) is released, it tries to return to the release direction by the force of the return spring (26). The brake lever (20) returns by the amount of switching play (S) between the base (21) of the brake lever (20) and the output link member (30), but the brake lever can be reduced by minimizing the switching play (S). The play of (20) is minimized.

  The claw member (40) is attached to the direction of engagement with the tooth (12a) of the ratchet plate (12) and the direction of separation by the turnover spring (45) interposed between the output link member (30). When the force is first applied to the tip (23) of the brake lever (20), it is biased in the direction of meshing with the teeth (12a) of the ratchet plate (12).

When the force applied to the brake lever (20) is removed and the return spring (26) returns by the switching play (S), the switching holding member (55) is also displaced in accordance with the displacement of the base (21) of the brake lever (20). To do. Due to this displacement, the engagement between the switching end (52) of the engagement / disengagement switching member (50) and the switching holding member (55) is released and the engagement / disengagement switching member (50) is released , and the switching biasing spring (57) With the brake lever (20) stopped, the engagement / disengagement switching member (50) swings to the release position and urges the claw member (40) in a direction to mesh with the teeth (12a) of the ratchet plate (12). The turnover spring (45) that has been turned is reversed so as to urge the claw member (40) in a direction to detach from the teeth (12a) of the ratchet plate (12). Even if the direction of biasing the claw member (40) is reversed, when the claw member (40) meshes with the teeth (12a) of the ratchet plate (12) by the braking force, the claw member (40) is retained by the frictional force and is clawed. The member (40) will not come off.

  In this way, a force is applied to the tip (23) of the brake lever (20), the brake cable (C) is pulled according to the swing of the brake lever (20), the brake is applied, and the claw member is released when the force is released. (40) meshes with the teeth (12a) of the ratchet plate (12) to maintain the braking state, and when the brake lever (20) is displaced in the return direction by the return spring (26), the pawl member (40) With the braking state maintained, the urging force is applied in the direction of detaching from the teeth (12a) of the ratchet plate (12), and the braking state is maintained.

  When releasing the brake from the braking state, if the force is applied again to the brake lever (20), the pawl member (40) is detached from the teeth (12a) of the ratchet plate (12) by the biasing force of the turnover spring (45). When the force is removed from the brake lever (20) and the output link member (30), the brake can be released by rotating in the braking release direction. When the brake lever (20) returns to the original position, the engagement / disengagement switching member (50) comes into contact with a part of the base (10) to return to the original braking position.

  In the case where the brake cable (C) is wound around and connected to the output link member (30), the brake cable (C) is smoothly pulled around the output link member (30) to generate a braking force. When the engagement / disengagement switching member (50) is pivotally attached to the output link member (30) coaxially with the claw member (40), the link is simplified and layout is easy. A device that applies force by stepping on the tip (23) of the brake lever (20) can appropriately operate the manual brake device (1) with a foot that cannot be moved dexterously compared to the hand.

  According to the manual brake device of the present invention, since the engagement / disengagement switching member is oscillated and displaced between the braking position and the release position and switched, it operates smoothly and reliably, and a decrease in braking force can be suppressed to a small level. It can be easy to operate.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
Each figure shows an embodiment of the present invention.
The manual brake device 1 is configured such that a base 21 of a brake lever 20 is pivotally supported by a main support shaft 11 on a base 10 fixed to a vehicle body, and a distal end portion 23 of the brake lever 20 is extended in the vicinity of an operator. It has become. A force is applied to the toe shoe 23a of the distal end portion 23, and the brake cable C is pulled in accordance with the swing of the brake lever 20 to apply a brake. The brake lever 20 can be a stepping type that applies a force by stepping on the toe shoe 23a of the tip 23, but can also be applied to a manual type.

  An output link member 30 to which the brake cable C is coupled to the main support shaft 11 coaxial with the brake lever 20 is pivotally supported by the base 10. An engagement hole 31 is formed in the output link member 30, and a power transmission pin 25 fixed to the base 21 of the brake lever 20 is fitted through a switching play S.

  A pawl member 40 that meshes with the teeth 12a of the ratchet plate 12 fixed to the base 10 and maintains a braking state is pivotally supported on the output link member 30 by a pivot pin 41, and the brake lever 20 The engagement / disengagement switching member 50 interposed between the output link member 30 and the output link member 30 is pivotally attached to the output link member 30 by a pivot pin 41 coaxial with the claw member 40. Although it is not necessary to be coaxial, the configuration is simplified if it is coaxial.

  The output link member 30 is pushed by the base 21 of the brake lever 20 via the engagement / disengagement switching member 50 and swings in one direction from the non-braking position to pull the brake cable C that is connected and pulls the braking force. Is generated. The brake cable C may be simply connected without being wound.

  A switching holding member 55 is fixed to the base 21 of the brake lever 20, and the switching holding member 55 has an engagement / disengagement end 56 that engages / disengages with the engagement / disengagement switching member 50. The engagement / disengagement switching member 50 is pivotally mounted on the output link member 30 coaxially with the claw member 40 so as to be swingable between a braking position and a release position, and has a switching end 52 that engages / disengages with the engagement / disengagement end 56 of the switching holding member 55. Have. The engagement / disengagement switching member 50 is urged toward the release position by a switching urging spring 57, and a stopper 58 is provided on which the engagement / disengagement end 56 of the switching holding member 55 contacts at the release position. An elastic body is attached to the stopper 58.

  The claw member 40 is supported by a turnover spring 45 interposed between the engagement / disengagement switching member 50 so as to be biased and retained in the direction in which the claw end 42 is engaged with the tooth 12a of the ratchet plate 12 and the direction in which the claw end 42 is detached. Has been.

  When the engagement / disengagement switching member 50 is in the braking position, the switching end 52 is engaged with the engagement / disengagement end 56 of the switching holding member 55, so that the force applied to the brake lever 20 is removed and the base 21 is switched by the return spring 26. The switching end 52 is disengaged from the engagement / disengagement end 56 due to the displacement of the switching holding member 55 when the play S returns, and the engagement / disengagement switching member 50 is moved from the engagement / disengagement end 56 to the stopper 58 by the urging force of the switching urging spring 57. The turnover spring 45 that oscillates to the abutting release position and biases the claw member 40 in a direction to engage the teeth 12a of the ratchet plate 12 is released from the claw member 40 from the teeth 12a of the ratchet plate 12 It is arranged to reversely bias.

  The manual brake device 1 applies a force to the toe shoe 23a of the distal end portion 23 of the brake lever 20, applies the brake by pulling the brake cable C according to the swing of the brake lever 20, and removes the force to release the foot from the toe shoe 23a. Sometimes the claw end 42 of the claw member 40 meshes with the teeth 12a of the ratchet plate 12 to maintain the braking state.

  When the brake lever 20 is displaced in the return direction by the return spring 26, the claw member 40 is in a detachment urging state in which the claw member 40 is urged away from the teeth 12a of the ratchet plate 12 while maintaining the braking state. When force is applied again to the brake lever 20, the claw end 42 of the claw member 40 is disengaged from the teeth 12a of the ratchet plate 12, and the force is removed therefrom to release the foot from the toe shoe 23a. When the brake lever 20 and the output link member 30 are rotated in the brake release direction to release the brake and the brake lever 20 returns to the original position, the return roller 59 of the engagement / disengagement switching member 50 is formed in a part of the base 10. It is configured to return to the original position by contacting the return end 15.

Next, the operation will be described.
When a force is applied by stepping on the toe shoe 23a of the tip 23 of the brake lever 20 with the base 21 pivotally supported on the base 10 fixed to the vehicle body, the base 21 of the brake lever 20 is pushed by the swing of the brake lever 20. As a result, the output link member 30 swings in one direction from the non-braking position to pull the connected brake cable C to generate a braking force.

  That is, when force is applied by stepping on the toe shoe 23a of the tip 23 of the brake lever 20 from the original position before braking in FIGS. 1 and 2, the play is switched from the power transmission pin 25 fixed to the base 21 of the brake lever 20. At the end of S, force is transmitted to the output link member 30 and rotated about the main support shaft 11, and the brake cable C is pulled.

  When the output link member 30 is rotated as shown in FIG. 3, the claw member 40 pivotally supported by the output link member 30 moves while meshing with the teeth 12 a of the ratchet plate 12 fixed to the base 10. . When a moderate braking force is obtained, when the force is released to release the foot from the toe shoe 23a of the tip 23 of the brake lever 20, the claw end 42 of the claw member 40 has the tooth 12a at that position as shown in FIG. And the output link member 30 is prevented from returning and the braking state is maintained.

  The engagement / disengagement switching member 50 is pivotally attached to the output link member 30 so as to be able to swing between a braking position and a release position, and is in the braking position when a force is applied to the distal end portion 23 of the brake lever 20. When the toe shoe 23a at the distal end portion 23 of the brake lever 20 is released, the brake lever 20 is rotated about the main support shaft 11 by the force of the return spring 26 to return to the release direction. Then, the power transmission pin 25 fixed to the base 21 of the brake lever 20 moves to the end of the switching play S in the return direction. The brake lever 20 returns by the amount of play that moves, but the play of the brake lever 20 is minimized by minimizing the switching play S.

  The claw member 40 can be urged and held in a direction to mesh with and disengage from the teeth 12a of the ratchet plate 12 by a turnover spring 45 interposed between the claw member 40 and the engagement / disengagement switching member 50. When a force is applied to the distal end portion 23 of the lever 20, the lever 20 is biased in a direction to mesh with the teeth 12 a of the ratchet plate 12.

  When the force applied to the brake lever 20 is removed and the return spring 26 returns by the switching play S, the switching holding member 55 is also displaced with the displacement of the base 21 of the brake lever 20. Due to this displacement, the engagement between the switching end 52 of the engagement / disengagement switching member 50 and the switching holding member 55 is released and the engagement / disengagement switching member 50 is released. The engagement / disengagement switching member 50 is stopped by the biasing force of the switching biasing spring 57. Swings to the release position where it contacts the engaging / disengaging end 56 of the switching holding member 55.

  As a result, as shown in FIG. 5, the turnover spring 45 that has urged the claw member 40 in the direction of meshing with the teeth 12 a of the ratchet plate 12, and the claw member 40 has the claw end 42 of the ratchet plate 12 It reverses so that it may urge in the direction which separates from 12a. Even if the direction of urging the claw member 40 is reversed, when the claw end 42 of the claw member 40 is engaged with the teeth 12a of the ratchet plate 12 by the braking force, the claw member 40 is released by being held by the frictional force. There is nothing.

  In this way, force is applied to the distal end portion 23 of the brake lever 20, and the brake cable C is pulled to perform braking in accordance with the swing of the brake lever 20. When the force is released, the claw member 40 has the teeth 12a of the ratchet plate 12. When the brake lever 20 is displaced in the return direction by the return spring 26, the pawl member 40 is urged in the direction of separating from the teeth 12a of the ratchet plate 12 while maintaining the braking state. And the braking state is maintained.

  As shown in FIG. 6, when braking is released from the braking state, if the force is applied again to the brake lever 20, the friction between the claw end 42 of the claw member 40 and the teeth 12a of the ratchet plate 12 disappears, and the claw member 40 is reversed. The claw end 42 is disengaged from the teeth 12 a of the ratchet plate 12 by being reversed by the biasing force of the turnover spring 45.

  As shown in FIG. 7, when the force is removed from the toe shoe 23a to release the foot, the brake lever 20 and the output link member 30 can rotate in the braking release direction to release the brake. As shown in FIGS. 8 to 9, when the brake lever 20 returns to the original position, the return roller 59 of the engagement / disengagement switching member 50 comes into contact with the return end 15 provided in a part of the base 10, and Return to the braking position.

  In the case where the brake cable C is wound around and connected to the output link member 30, the brake cable C is smoothly pulled around the output link member 30 to generate a braking force. When the engagement / disengagement switching member 50 is pivotally attached to the output link member 30 coaxially with the claw member 40, the link is simplified and layout is easy.

  A device that applies a force by stepping on the tip 23 of the brake lever 20 with a foot can appropriately operate the manual brake device 1 with a foot that cannot be moved dexterously compared to a hand.

The engagement / disengagement switching member is pivotally mounted on the output link member coaxially with the claw member so as to be swingable between a braking position and a release position, and engages / disengages with a switching holding member fixed to the base of the brake lever. Having a switching end,
The claw member can be biased and held in a direction of meshing with a tooth of the ratchet plate and a direction of separation by a turnover spring interposed between the engagement / disengagement switching member,
The switching end of the engagement / disengagement switching member and the switching holding member fixed to the base of the brake lever are engaged when a force is applied to the tip of the brake lever when in the braking position, When the force applied to the brake lever is removed and the return play is returned by the return spring, the engagement is released , and the brake lever is stopped by the switching biasing spring provided between the engagement / disengagement switching member and the brake lever. The turnover spring that oscillates the engagement / disengagement switching member to the release position in a state and urges the claw member in a direction to mesh with the teeth of the ratchet plate causes the claw member to move to the ratchet plate. Configured to urge in the direction of detachment from the teeth,
Applying force to the tip of the brake lever, pulling the brake cable according to the swing of the brake lever to apply braking, and when the force is released, the claw member meshes with the teeth of the ratchet plate to maintain the braking state. When the brake lever is displaced in the return direction by a return spring, the claw member is released from the ratchet plate while maintaining the braking state, and is released from the release bias state. When the force is applied to the brake lever again, the claw member disengages from the teeth of the ratchet plate, and when the force is removed from the tooth, the brake lever and the output link member rotate in the braking release direction to perform braking. Manual brake device characterized by releasing.   The manual brake device according to claim 1 or 2, wherein the brake lever applies a force by stepping on a tip portion with a foot.
