Description

  The present invention relates to an interlocking device for a plurality of members in a two-wheeled vehicle such as a bicycle or a motorcycle, and more specifically, one activation member (rear wheel brake device) which is disposed at at least two separated positions. A rear wheel brake device is provided by providing another driven member (for example, a handle lock) that is driven in response to the activation of the activation member, and further by arranging a transmission cable between the activation member and the driven member. By actuating, the handle lock can be driven with less force than the rear wheel brake device, or by locking one actuating member (for example, the front wheel brake device), it becomes looser than the front wheel lock device. By enabling the other driven member (for example, rotation of a crankshaft or a stand) to be locked by an operating force, a plurality of members can be locked. An object of the present invention is to smooth the interlocking actuation.

For example, by connecting a lock rod operating portion of a bicycle rear wheel lock and an interlocking lock rod portion of a linked front wheel by a transmission means such as a wire via an adjusting spring, one rear wheel lock having a different sliding width and the other rear wheel lock have different sliding widths. A system in which an interlocking lock portion of an interlocking front wheel lock is interlocked and one of the interlocking front wheel locks is interlockingly locked by locking one rear wheel lock has already been disclosed (Japanese Patent Application Laid-Open No. 2002-129814). Gazette).
JP-A-2002-129814

  However, in the above-mentioned interlocking locking means, the working distances of the wires are different from each other due to structural differences between a plurality of members attached to the motorcycle, and the working forces due to friction, compression or deformation of the wires are different. As a result, since the stress from the initial operation to the completion of the operation is not uniform, the interlocking of the plurality of members is not smooth, and it is very difficult to adjust the operation of the plurality of members at the same time. Furthermore, since a large initial differential force is required, the durability of wires and other operating parts due to excessive stress is reduced, and there is a problem that a large force is required for operation.

  Therefore, the present invention solves the above-described problems, and provides a means for interlocking a plurality of members that can smoothly operate in an interlocking manner in response to a difference in an operating distance and an initial differential force by a wire between a plurality of members and that does not impose an excessive operating stress. Specifically, the invention according to claim 1 is an invention in which the starting member and the driven member which is driven in response to the starting of the starting member are disposed at at least two separate positions. A transmission cable is connected and arranged between the starting member and the driven member, and a resilient means is disposed at a connection portion between the starting member side and the driven member side of the transmission cable, respectively. The present invention relates to an interlocking device for a plurality of members in a two-wheeled vehicle, wherein the starting member and the driven member are interlocked by the resilient action of the means.

  The invention according to claim 2 includes an activation member, a driven member that operates in response to activation of the activation member, and a transmission cable that connects the activation member and the driven member. A plurality of members in a two-wheeled vehicle, wherein a resilient means is interposed at a connection portion between the starting member side and the driven member side, and the resilient means has different resilient forces between the starting member side and the driven member side. Related to an interlocking device.

  Further, in the invention according to claim 3, the resilient means interposed between the starting member side and the driven member side are respectively constituted by springs, and the spring constant of the starting member side spring is 0.01 to 1.5, and the driven member is 3. The multi-member interlocking device according to claim 2, wherein a spring constant of the side spring is 0.05 to 2.0.

  Further, the invention according to claim 4 further comprises an activation member, a driven member that is driven in response to activation of the activation member, and a transmission cable that connects the activation member and the driven member. A plurality of two-wheeled motor vehicles characterized in that a resilient means is interposed at a connection portion between the member side and the driven member side, and the resilient means has a different moving distance absorption amount between the activation member side and the driven member side. The present invention relates to a member interlocking device.

  Further, the invention according to claim 5 is characterized in that one activation member of a lockable and unlockable lock member disposed at at least two separate positions, and the other activation member that is driven in response to activation of the activation member. 5. The driven member according to claim 1, wherein the driven member is a combination of a plurality of front wheel brakes, rear wheel brakes, front wheel locks, rear wheel locks, handle locks, crank locks, and stand locks. 6. The present invention relates to an interlocking device for a plurality of members in the motorcycle.

  Further, according to the invention of claim 6, the transmission cable connected and arranged between the starting member and the driven member is a metal wire having a diameter of 0.3 to 3.0Φ. A two-member interlocking device for a motorcycle according to claim 2. Further, in the invention according to claim 7, the transmission cable connected and arranged between the starting member and the driven member is a resin wire having a diameter of 1.0 to 5.0Φ. A two-member interlocking device for a motorcycle according to claim 2.

  The invention according to claim 8 is further characterized in that a track member provided with a retractable locking rod having a resilient means acting in a retreating direction attached to one end, and a driven member that is driven to actuate the activation of the activation member. And a transmission cable connecting the actuating member and the driven member. A spring means is disposed at each of a connection portion of the transmission cable with the lock rod and a connection portion of the driven member with the driven member. The present invention relates to an interlocking device for a plurality of members in a motorcycle, wherein locking and unlocking of the starting member and the driven member are performed by a resilient action of the means.

  In the above configuration, when one of the members is activated, the transmission cable is pulled along with the activation, and the connection portion of the other member connected to the far side of the transmission cable is pulled and operates in a driven manner. At the connecting part of the starting-side member and the connecting part of the driven-side member, resilient means having different moving distance absorption amounts are interposed, so that the operating force gradually changes for the actual operation of multiple members. As a result, there is a substantial time lag, and consequently no simultaneous actuation, so that the actuation forces are relatively averaged, operation is smooth and no excessive stress is required.

  As described above, the present invention activates one of a plurality of members attached to a motorcycle so that the other member is driven to be driven via a transmission line, and the transmission line A resilient means is disposed at a connection portion between the starting member side and the driven member side of the starting member, the starting member and the driven member are interlocked by the resilient action of the resilient means, and the resilient means is connected to the starting member side. Since the resilient force is made different between the driven member side and the stepping means, the moving distance absorption amount is made different between the starting side and the driven side, the following effects are obtained.

  In other words, even if the working distances of the wires are different from each other due to the structural difference between a plurality of members attached to the motorcycle and the working force is different due to the friction, compression or deformation of the wires, the interlocking that connects the members A spring is interposed in the connecting part of the cable, and the spring force of the springs is made different to make the moving distance absorption amount of the wire different between the starting side and the driven side. Since it gradually changes and causes a substantial time lag and does not operate at the same time, the operating force is relatively averaged, eliminating excessive stress load at the time of initial operation and operating from initial operation to completion of operation The force can be averaged, which allows smooth interlocking of multiple members, improving operational feeling and improving durability. Can.

  Hereinafter, the specific contents of the present invention will be described with reference to the principle diagram shown in FIG. 1. 1 a is a fixed frame of the starting member 1, 7 a is a fixed frame of the driven member 7, and 4 is a fixed frame of the starting member. A wire interposed between the fixed frame 1a and the fixed frame 7a of the driven member is shown. One end of the wire 4 is attached to the fixed frame 1 a of the activation-side member 1.

  For mounting, the operating rod 2 of the starting member 1 is slidably interposed on the wire 4 that has passed through the wire hole of the fixed frame 1a of the starting member 1 via the wire mounting hole or the like of the operating rod. Further, an adjusting spring 6 is inserted following the operating rod 2, and the opposite end of the adjusting spring 6 is fixed to an end of the wire 4 by a stator 5.

  On the other hand, the opposite end of the wire 4 passes through the wire hole of the fixed frame 7 a of the driven member 7, and the end of the wire 4 projecting therethrough is inserted with a return spring 8 to interpose the interlocking rod of the driven member 7. Fix it at 9. Reference numeral 3 denotes an outer cable that covers a wire interposed between the fixed frame 1a of the starting member 1 and the fixed frame 7a of the driven member 7. The wires used in this case include metal wires such as steel wires or SUS steel wires, or resin wires (high-strength resin wire ropes) and other power cables with excellent tensile strength and wear resistance. Any of them can be used.

  When a metal wire is used, if the thickness is less than 0.3Φ, it is too thin to be easily assembled, and it is easy to cut, and it is easy to bend. Therefore, there is no durability to withstand long-term use. If it exceeds, the radius of curvature becomes too large, so that it is difficult to assemble the bicycle along with the frame of the bicycle, and the appearance is deteriorated. Therefore, the diameter of the thickness: in the range of 0.3 to 3.0Φ, Preferably, the diameter is in the range of 0.5 to 1.5Φ.

  When a resin wire is used, the safety factor is set to 2, and the wear amount is set to 10% and the elongation is set to 5% or less. Further, even if the diameter exceeds 5.0Φ, a problem arises in assemblability. Therefore, the diameter of the diameter is preferably in the range of 1.0 to 5.0Φ, more preferably in the range of 2 to 3Φ.

  In the above configuration, when the operating rod 2 of the activation-side member 1 is moved in a direction (leftward in FIG. 1) in which the operating rod 2 is separated from the fixed frame 1a against the resiliency of the adjusting spring 6, The wire 4 is slid and moved leftward in FIG. 3 via the stator 5 while the adjusting spring 6 is gradually pressed. Further, the movement of the wire 4 to the left pulls the interlocking rod 9 of the driven side member 7 toward the fixed frame 7a while gradually pressing the return spring 8, thereby operating the operating rod 2 of the activation side member 1. The single operation allows the interlocking rod 9 of the driven member 7 to be operated simultaneously.

  Therefore, in this case, if the resilient forces of the adjusting spring 6 and the return spring 8 are made different from each other, for example, in the case of elastic force = adjusting spring 6> return spring 8, the operating rod 2 of the activation-side member 1 is moved. When moved to the left, the interlocking rod 9 of the driven side member 7 moves toward the fixed frame 7a at a stress ratio of 1: 1. On the other hand, in the case of elasticity = adjusting spring 6 <return spring 8, the operating rod 2 of the starting member 1 is largely moved to the left to move the interlocking rod 9 of the driven member 7 toward the fixed frame 7a. Can be moved small.

  More specifically, the spring constant of the above-mentioned adjustment spring can be set arbitrarily. That is, if the spring constant of the spring on the activation member side is less than 0.01, the spring is too weak, and even if the operating rod 2 is moved to the left, only the adjusting spring 6 is compressed. It is difficult to move the necessary distance. On the other hand, even if the distance exceeds 1.5, a large force is required to move the operating rod 2 to the left and compress the adjustment spring 6, and it is difficult to operate with the fingers of a human hand. .

  As described above, in any of the above cases, inconvenience occurs, so that it is practically necessary to be within the range of 0.01 to 1.5. Also, if the spring constant of the driven side member is less than 0.05, the total force of the force for returning the interlocking rod 9 to the original position and the frictional force between the outer wire 3 and the wire 4 is less than the original position. Cannot be returned to On the other hand, even if it exceeds 2.0, in order to compress the return spring 8 and move the interlocking rod 9 to the target distance, the spring constant of the adjusting spring 6 must be increased, and the operating force of the entire operating rod must also be increased. As a result, practical operability is lost. For that purpose, it is preferable to set within the range of 0.05 to 2.0.

    By setting the spring constant to a suitable value as described above, even if the stroke lengths of the springs are the same or different, the operation of the starting-side member and the driven-side member can be performed simultaneously or simultaneously. Any of the delays can be accommodated. Further, the stroke value of the adjusting spring is set to be about 65 mm for the starting member side (for example, a circle lock) and about 8.5 mm for the driven member side (for example, a head lock), and that 1 ≦ stroke value ≦ 10. Is preferred.

  Thus, the adjustment spring 6 inserted between the operating rod 2 of the starting member 1 and the stator 5 and the return spring interposed between the fixed frame 7a of the driven member 7 and the interlocking rod 9 By making the resilience of the members 8 different from each other in accordance with the application, a substantial time lag can be caused between the members 1 and 7 in operation, so that operability is good and more reliable operation is possible. can do.

  In the following, a case where the present invention is applied to a horseshoe-shaped circle lock attached to the rear wheel of a bicycle as the starting member 1 and to a head lock attached to a handle as the driven member 7 will be described with reference to FIG. The circle lock and the headlock in this case have a basic structure known per se, and a detailed description of those structures is omitted, but the connection portion with the wire 4 has a unique feature. is there.

  That is, in the circle lock which is the activation-side member 1, as shown in FIG. 3, the circular frame of the circle lock itself becomes the fixed frame 1a, and one end of the outer cable 3 is fixed to the fixed frame 1a. One end of the wire 4 is slid through an operation knob 2 integrally attached to the cannula 2A to operate the cannula 2A slidably accommodated in the circular frame 1a through the wire mounting hole of the operation rod. In addition to being freely interposed, an adjustment spring 6 is further inserted following the operation knob 2, and the opposite end of the adjustment spring 6 is fixed to the wire 4 by a stator 5. In FIG. 3, the chain line indicates the position of the operating knob 2 at the time of movement (the state where the adjustment spring 6 is compressed).

  The head lock, which is the driven member 7, will be described with reference to FIGS. 4 and 5 in which the head lock is incorporated in the steering head to which the handle post 10 is attached as the driven member 7. The headlock device in this case has a structure known per se, and a detailed description of those structures is omitted. However, similar to the above-described activation-side member 1, a connection portion with the wire 4 is provided. It has unique features.

  That is, in the handle lock, which is the driven side member 7, as shown in FIGS. 4 and 5, the stator of the wire mounting bolt serves as the fixed frame 7a, and one end of the outer cable 3 is fixed to the fixed frame 7a. A return spring 8 is interposed between the wire 4 protruding from the frame 7a into the driven member 7 and a distal end thereof is integrally attached to a stopper key 9a which advances and retreats into a lock groove of a lock gear 11 integrated with the handle post 10. It is fixed to the interlocking frame 9.

  In the configuration of the above-described embodiment, the resilient force of the adjustment spring 6 on the circle lock side as the activation side member 1 is made weaker than that of the return spring 8 on the head lock side as the driven side member 7 to absorb the moving distance of the wire 4. In the case where the amount is varied, when the operating rod 2 protruding from the long groove of the circle lock which is the activation side member 1 is moved in the front direction in FIG. 2, the kanuki 2A is thereby fixed to the fixed frame (circular frame) 1a. Inside the fixed frame 1a on the opposite side across the horseshoe-shaped opening and locked.

  At this time, since the return spring 8 has higher resilience, a substantial time lag occurs when the interlocking frame 9 is pulled by the wire 4, and the interlocking frame 9 finally operates just before the locking of the circle lock is completed. Then, the head lock device is locked accordingly.

  On the other hand, the elastic force of the adjustment spring 6 on the circle lock side, which is the activation side member 1, is made stronger than that of the return spring 8 on the head lock side, which is the driven side member 7, so that the moving distance absorption amount of the wire 4 is made different. In this case, a substantial time lag also occurs in the pulling of the interlocking frame 9 by the wire 4, and when the operating rod 2 protruding from the long groove of the circle lock, which is the activation-side member 1, is moved toward the front in FIG. Since the resilient force is higher, the wire 4 is immediately pulled and the interlocking rod 9 is pulled against the resilient force of the weak return spring 8, so that the head lock device is locked first, and then the starting side The locking of the circle lock side as the member 1 is performed.

  Next, FIG. 6 is a graph showing the result of an experiment on the relationship between the operating force and the operating length of the wire when the present invention is applied to the starting member (circle lock) 1 and the driven member (head lock device) 7. . As shown in the graph, when there is no spring, when the A component is operated, the operation force of only the A component is applied up to P1, but since the operation force of the B component is also applied from P1, the operation torque increases at a stretch. On the other hand, in the case with the spring, when the component A is operated, the operation force of the component B is applied from the position P2, and the operation torque is averaged because the operation force is gradually increased. Therefore, the operation feeling does not feel heavy. .

  As can be understood from this, when the A component (circle lock) and the B component (head lock device) are linked according to the present invention, as compared with the case of the A component (circle lock) or the B component (head lock device) alone. Although the operating force slightly increases, the operating force of both parts is relatively averaged compared to the case without a spring, and the operability is further improved.

  In the above embodiment, the case where the circle lock is applied as the starting member 1 and the head lock device is applied as the driven member 7 has been described. However, the present invention is not necessarily limited to this. For example, two or more members attached to the bicycle may be provided between the front wheel brake device and the stand lock, or between the front wheel brake, the rear wheel brake, the front wheel lock, the rear wheel lock, the handle lock, the crank lock, and the stand lock. Of these, a plurality of combinations are also applicable.
