Description

  The present invention relates to a bicycle hand switch, and relates to a technique for fixing a bicycle hand switch to a handlebar.

  Conventionally, an electric assist bicycle has a hand switch for controlling an electric assist function on a handlebar. For example, Patent Document 1 discloses a hand switch for this electric assist bicycle.

  As shown in FIGS. 17 and 18, this is a hand switch 102 to be attached to the handle bar 101, and includes a switch mounting portion 103 and a band portion 104 for fixing the switch mounting portion 103 to the handle bar 101.

  The switch mounting portion 103 includes a planar switch mounting surface 105 that is parallel to the axis of the handle bar 101. The switch mounting surface 105 is provided with a liquid crystal information display unit 106, information selection instruction switches 107 and 108, a determination switch 109, a power switch 110, a clear switch 111, and the like. A button 112, a mode switching button 113, and the like are provided.

  The band unit 104 includes a band main body 114 that is fixed to the switch mounting unit 103, and a saddle band 115 that is fixedly supported by the band main body 114 and straddles the handle bar 101. The band portion 104 as a whole has a split shape around the axis of the handle bar 101, and the end portion 114 a of the band main body 114 and the end portion 115 a of the saddle band 115 are opposed to each other through the split opening 116.

  Then, the tightening force of the fixing screw 117 acts in a direction in which the end portion 114a of the band main body 114 and the end portion 115a of the saddle band 115 approach each other, whereby the band main body 114 and the saddle band 115 are connected to the handlebar. It is tightened to 101.

JP 2007-145277 A

  The original inner diameter of the band section 104, that is, the inner diameter of the band section 104 in a free state in which the fastening force of the fixing screw 117 is released, is formed to be equal to or slightly larger than the outer diameter of the handle bar 101. The fastening force of the fixing screw 117 acts against a restoring force that the band portion 104 tries to return to the original inner diameter.

  In the locked state, the inner diameter of the band portion 104 coincides with the outer diameter of the handle bar 101, and the inner peripheral surface of the band portion 104 is pressed against the outer peripheral surface of the handle bar 101 by the tightening force of the fixing screw to handle the band portion 104. The switch mounting part 103 and the band part 104 are prevented from rotating around the axis of the handle bar 101 by being fixed to the bar 101.

  As described above, the fixing force of the band portion 104 is a force that presses the inner peripheral surface of the band portion 104 against the outer peripheral surface of the handle bar 101, that is, presses the inner peripheral surface of the band portion 104 in a direction in which the inner diameter of the band portion 104 is reduced. This depends on the tightening force of the fixing screw 117 to be fixed. For this reason, when the fixing screw 117 is loosened due to secular change or the band portion 104 is deteriorated, the inner peripheral surface of the band portion 104 is separated from the outer peripheral surface of the handle bar 101 by receiving the restoring force of the band portion 104. As a result, the fixing force of the band portion 104 rapidly decreases, causing the switch mounting portion 103 to rotate around the axis of the handlebar 101.

  The force of the finger pressing the switch acts in the direction of rotating the switch mounting portion 103 around the axis of the handle bar 101. The force applied by a single operation is slight, but when the switch mounting portion 103 rotates around the axis of the handlebar 101 and the mounting angle of the switch mounting portion 103 changes as the time passes, the switch The operation may be difficult, and it is a problem to suppress the deterioration of the fixing force due to secular change for ensuring safety.

  In addition, the switch mounting portion 103 has a plurality of switches arranged on a flat switch mounting surface 105 along the axial direction of the handlebar 101 and in a planar manner. For this reason, the driver cannot operate the switches with his / her fingers while holding one end of the handlebar 101 with his / her hand, and needs to release the hand from the handlebar 101 to operate the switch. During this time, the driver needs to grasp the handlebar 101 with the other hand and operate the handle with one hand, which has a problem in ensuring driving safety.

  The present invention can suppress deterioration of the fixing force of the band part due to secular change, and can stably hold each switch at a wide range of positions within the range of movement of the hand of the hand holding the handlebar. An object of the present invention is to provide a bicycle hand switch that can be operated without any problems.

  In order to solve the above-mentioned problem, a hand switch for a bicycle according to the present invention has a single slot, a band portion that is annularly mounted around the shaft center of the handlebar, and a band portion in the radial direction of the handlebar. A switch mounting portion provided on the outside and a band lock portion to be attached to one band end facing the slot, the band lock portion including a bar outer peripheral surface of the handlebar and a band end inner surface facing the bar outer peripheral surface. A wedge portion having a wedge to be inserted between the wedge portion, a wedge portion connected to one band end portion, and a wedge pushing portion for pushing the wedge between the bar outer peripheral surface and the band end inner surface To do.

In the bicycle hand switch of the present invention, the wedge portion is detachable between a position where the split opening is closed and a position where the split opening is opened.
In the bicycle hand switch according to the present invention, the wedge portion is swingably connected to the other band end facing the split port by a support shaft.
In the bicycle hand switch of the present invention, the wedge part is formed integrally with the other band end part facing the split and bendable.
In the bicycle hand switch of the present invention, the band portion has an opening dimension corresponding to the diameter of the handle bar.

In the bicycle hand switch of the present invention, the band portion includes an anti-slip material that is in pressure contact with the outer peripheral surface of the handle bar.
In the bicycle hand switch according to the present invention, the wedge pushing portion includes a fixing screw having a head portion engaged with the wedge portion and a shaft portion screwed into one band end portion.
In the bicycle hand switch of the present invention, the switch mounting portion is characterized in that a plurality of switches are arranged in a line along the axis of the handlebar.
The bicycle hand switch of the present invention is characterized in that the switches of the switch mounting portion are arranged in the movable range of the fingers of the hand holding the handlebar.

  In the bicycle hand switch of the present invention, the switch mounting portion has a plurality of mounting portions arranged along the axis of the handlebar, and the switch mounting surface formed on each mounting portion is around the axis of the handlebar. A group of switches that face different directions and are related to operation are arranged for each switch mounting surface.

According to the bicycle hand switch of the present invention, the band lock portion inserts the wedge between the bar outer peripheral surface of the handle bar and the band end inner surface facing the bar outer peripheral surface. The peripheral surface is pressed against the bar outer peripheral surface of the handle bar.
That is, the band part is pressed in a direction in which one band end part is separated from the handle bar by the insertion of the wedge, and the band inner peripheral surface on the side opposite to the wedge through the handle bar is the outer periphery of the handle bar bar. Pressed against the surface.
At this time, the tightening force of the fixing screw acts via the wedge booster mechanism, so that the band inner peripheral surface is pressed against the bar outer peripheral surface with a strong force, and the band portion fixing force becomes stronger. The switch mounting part is reliably prevented from rotating around the handlebar axis.

Further, a restoring force is generated in the band portion so as to return to the original state against the pressing force of the wedge acting on one band end portion. For this reason, even if the position of the wedge is retracted due to secular change, the band end inner surface and the wedge are maintained in pressure contact with the restoring force of the band, and the wedge boosting mechanism continues to operate, The pressing force on the outer peripheral surface of the bar is maintained, and the rotation of the band portion and the switch mounting portion is permanent.
As the wedge part is connected to the other band end facing the slot, the wedge is inserted in a state where the expansion of the slot is restricted, so that the fixing force of the band part is increased and the durability of the fixing force is improved. .

Moreover, since the split part of a band part has the opening dimension according to the diameter of a handle bar, a handle bar can be inserted in a band part through a split part, and it can arrange | position in the state which straddled the band part over the handle bar. Therefore, it is not necessary to insert the band portion from the distal end side of the handle bar and send it out in the axial direction of the handle bar, and the band portion can be directly attached to the middle position of the handle bar.
The band part receives a pressing force applied by the wedge booster with an anti-slip material having a larger friction coefficient than the inner peripheral surface of the band and presses against the outer peripheral surface of the bar to further increase the frictional force. Becomes more powerful.
Since the fixing force of the band part around the axis of the handlebar is improved, even if the force of the fingers operating the switch repeatedly acts in the direction of rotating the switch mounting part around the axis of the handlebar, the force On the other hand, the fixing force of the band part can be made permanent.

Further, an area necessary for arranging a plurality of switches in a line along the axis of the handlebar can be secured by extending the switch mounting portion along the axis of the handlebar. For this reason, the switches can be arranged within the movable range of the fingers, and each switch can be operated with both hands holding the handlebar, thereby improving the safety of the bicycle driving operation.
The switch mounting part has a switch mounting surface formed on each mount part facing in a different direction around the axis of the handlebar, so that the driver can touch which switch part mounting surface with his / her finger. You can easily recognize if you are. Therefore, by arranging a group of switches related to the operation on each switch mounting surface, it is possible to prevent an unintentional erroneous operation.

The switch 44 mounted on the switch mounting surface 43 is not limited to the one described above, and a switch for controlling other devices can be mounted.

  In the first embodiment, the bicycle hand switch 1 is a cord (not shown) inserted through the cord outlet 4a of the switch mounting portion 4 and connected to the drive unit, the control unit of the speed change mechanism, and the battery (not shown). Yes. Power can be supplied to the bicycle hand switch from a separately provided battery.

The band lock portion 5 is attached to one band end portion 34 facing the slot 31 and includes a wedge portion 51 and a wedge pushing portion 52.
The wedge part 51 is detachable between a position where the split 31 is closed and a position where the split 31 is opened, and between the bar outer peripheral surface 21 of the handle bar 2 and the band end inner surface 35 facing the bar outer peripheral surface 21. A wedge 51a to be inserted into the band and a connecting portion 53 to be connected to the band end 34. A through hole 54 is provided in the connection portion 53.
The wedge pushing portion 52 connects the wedge portion 51 to one band end portion 34 and pushes the wedge 51a between the bar outer peripheral surface 21 and the band end portion inner side surface 35. Here, the wedge pushing portion 52 includes a fixing screw 55. . The fixing screw 55 is disposed through the through hole 54 of the connection portion 53 of the wedge portion 51, the head portion 55a is engaged with the connection portion 53, and the shaft portion 55b is disposed on the one band end portion 34. Threaded onto.

The operation of the first embodiment having the above-described configuration will be described.
As shown in FIG. 2, the bicycle hand switch 1 is inserted and attached from one end side of the bicycle handlebar 2 before the grip 22 is attached here. That is, the fixing screw 55 of the band lock part 5 is loosened, the wedge part 51 is removed, and the slit 31 is opened. Then, the handle bar 2 is inserted into the opening of the band unit 3, and the band unit 3 and the switch mounting unit 4 are moved in the axial center (X) direction of the handle bar 2 and arranged at a predetermined specific target position.
Then, as shown in FIGS. 1 and 3, the band lock portion 5 is attached to one band end portion 34 with a fixing screw 55. The shaft portion 55 b of the fixing screw 55 is screwed into the nut 36 and tightened, and the connecting portion 53 of the wedge portion 51 that engages with the head portion 55 a is pressed against one band end portion 34.

As the tightening operation of the fixing screw 55 proceeds, the wedge 51 a is inserted between the bar outer peripheral surface 21 of the handle bar 2 and the band end inner surface 35 facing the bar outer peripheral surface 21. The band inner peripheral surface 32 of the band portion 3 is pressed against the bar outer peripheral surface 21 of the handle bar 2 by the insertion of the wedge 51a.
That is, the band portion 3 is pressed in a direction in which one band end portion 34 is separated from the bar outer peripheral surface 21 of the handlebar 2 by the insertion of the wedge 51a, and is opposite to the wedge 51a via the handlebar 2. The band inner peripheral surface 32 is pressed against the bar outer peripheral surface 21 of the handle bar 2.

At this time, the fastening force of the fixing screw 55 acts via the booster mechanism of the wedge 51a, so that the band inner peripheral surface 32 is pressed against the bar outer peripheral surface 21 with a strong force, and the fixing force of the band portion 3 is strong. Thus, the band portion 3 and the switch mounting portion 4 are reliably prevented from rotating around the axis (X) of the handlebar 2.
Further, in the band portion 3, a restoring force is generated to return to the original pressure against the pressing force of the wedge 51 a acting on the one band end portion 34. For this reason, even if the position of the wedge 51a retreats due to secular change, the pressure contact state between the band end inner side surface 35 and the wedge 51a is maintained by the restoring force of the band portion 3. For this reason, since the booster mechanism of the wedge 51a continues to act, the force that presses the band inner peripheral surface 32 against the bar outer peripheral surface 21 is maintained, and the rotation of the band portion 3 and the switch mounting portion 4 is permanent.

Further, the band part 3 receives a pressing force applied by the booster mechanism of the wedge 51a by the anti-slip material 33 having a friction coefficient larger than that of the band inner peripheral surface 32, and thereby the frictional force is further increased. As a result, the fixing force of the band part 3 becomes stronger.
As described above, the fixing force of the band portion 3 around the axis (X) of the handlebar 2 is improved, so that the force of the fingers operating the switch 44 moves the switch mounting portion 4 around the axis (X) of the handlebar 2. Even if it repeatedly acts in the direction in which it is rotated, the fixing force of the band portion 3 can be made permanent against the force.
Further, an area necessary for arranging the plurality of switches 44 in a line along the axis (X) of the handlebar 2 is the switch mounting portion 4 along the axis (X) of the handlebar 2. Can be extended for a long time. For this reason, the switch 44 can be arranged in the movable range of the fingers, and each switch 44 can be operated in a state where the handlebar 2 is grasped with both hands, thereby improving the safety of the bicycle driving operation.

  Since the switch mounting surface 43 formed on each mount portion 42 faces the switch mounting portion 4 in different directions around the axis (X) of the handlebar 2, the driver mounts the mound portion 42 with his / her finger. It can be easily recognized whether it is in contact with the switch mounting surface 43. Therefore, by arranging a group of switches 44 related to the operation for each switch mounting surface 43, it is possible to prevent an unintentional erroneous operation. In addition, the occurrence of an erroneous operation can be prevented even when the swing direction of each switch 44 is different.

(Example 2)
Next, a bicycle hand switch according to the second embodiment will be described with reference to FIGS. Elements similar to those described in the first embodiment will be described with the same reference numerals.
As shown in FIG. 11, the bicycle hand switch 6 according to the second embodiment is of a type in which the band portion 7 can be directly attached to the middle position of the handlebar 2 of the bicycle. The base member is composed of a band portion 7 made of the same material such as a resin material, a switch mounting portion 4 and a band lock portion 8.

As shown in FIG. 15, the switch mounting portion 4 is the same as that described above with reference to FIG.
The band portion 7 has an annular shape around the axis (X) of the handle bar 2 and has one split 71. The slot 71 has an opening size corresponding to the diameter of the handle bar 2. As described above, since the split 71 of the band part 7 has an opening size corresponding to the diameter of the handle bar 2, the handle bar 2 is inserted into the band part 7 through the split 71, and the band part 7 is attached to the handle bar 2. It can be placed in a stretched state. Therefore, there is no need to insert the band portion 7 from the distal end side of the handle bar 2 and send it out in the axial center (X) direction of the handle bar 2, and the band portion 7 can be directly attached to the middle position of the handle bar 2. .

The band portion 7 has an anti-slip material 73 that is exposed to the band inner peripheral surface 72 along the axis (X) of the handle bar 2 and presses against the bar outer peripheral surface 21 of the handle bar 2. 73 is made of a rubber material having a friction coefficient larger than that of the inner circumferential surface 72 of the band. The anti-slip material 73 is positioned approximately in the center of the band portion 7 around the axis (X) of the handle bar 2.
The band lock portion 8 includes a wedge portion 81 and a wedge pushing portion 82. The wedge portion 81 is detachably attached to one band end portion 74 whose one end side faces the split slot 71, and swings around the support shaft 76 on the other band end portion 75 whose other end side faces the split slot 71. It is connected freely, and can swing over a position where the split 71 is closed and a position where the split 71 is opened. The wedge portion 81 has a wedge 81a inserted between the bar outer peripheral surface 21 of the handle bar 2 and the band end inner surface 74a facing the bar outer peripheral surface 21, and a connecting portion 83 connected to one band end portion 74. doing. The connecting portion 83 is provided with a through hole 84.

  The wedge pushing portion 82 connects the wedge portion 81 to one band end portion 74 and pushes the wedge 81a between the bar outer peripheral surface 21 and the band end portion inner side surface 74a. Here, the wedge pushing portion 82 includes a fixing screw 85. . The fixing screw 85 is inserted through the through-hole 84 of the connecting portion 83 of the wedge portion 81, the head portion 85 a is engaged with the connecting portion 83, and the shaft portion 85 b is disposed on one band end portion 74. Threaded onto.

The operation of the second embodiment having the above-described configuration will be described.
As shown in FIG. 11, the bicycle hand switch 6 is attached later to the handlebar 2 of the bicycle after the grip 22 is attached. That is, the fixing screw 85 of the band lock portion 8 is loosened, the wedge portion 81 is swung around the axis of the support shaft 76, and the split 71 is opened. Then, the handle bar 2 is inserted into the opening of the band portion 7, and the band portion 7 and the switch mounting portion 4 are arranged at a predetermined specific target position of the handle bar 2.
Then, as shown in FIGS. 10 and 12, the wedge portion 81 is swung around the axis of the support shaft 76 so that the split port 71 is closed, and the band lock portion 8 is fixed to one band with the fixing screw 85. Attach to the end 74. The shaft portion 85 b of the fixing screw 85 is screwed into the nut 86 and tightened, and the connection portion 83 of the wedge portion 81 that engages with the head portion 85 a is pressed against one band end portion 74.

As the tightening operation of the fixing screw 85 proceeds, the wedge 81a is inserted between the bar outer peripheral surface 21 of the handle bar 2 and the band end inner surface 74a facing the bar outer peripheral surface 21. By the insertion of the wedge 81a, the band inner peripheral surface 72 of the band portion 7 is pressed against the bar outer peripheral surface 21 of the handle bar 2.
That is, in the band portion 7, the band end portions 74, 75 on both sides via the slit 71 are connected to each other by the wedge portion 81, and when the wedge portion 81 a is inserted, one band end portion 74 side is positioned on the handlebar 2. The band inner peripheral surface 72 on the side opposite to the wedge 81 a is pressed against the bar outer peripheral surface 21 of the handle bar 2 through the handle bar 2.

As described above, the band inner peripheral surface 72 exerts a strong force on the bar outer peripheral surface 21 by the tightening force of the fixing screw 85 acting through the booster mechanism of the wedge 51a in a state in which the expansion of the slit 71 is restricted. As a result, the fixing force of the band portion 3 is increased and the band portion 3 becomes stronger, and the band portion 3 and the switch mounting portion 4 are reliably prevented from rotating around the axis (X) of the handlebar 2.
Further, since the expansion of the split 71 is restricted, the pressure contact state between the band end inner side surface 74a and the wedge 81a is maintained even if the fixing screw 85 is loosened due to secular change. For this reason, since the booster mechanism of the wedge 81a continues to act, the force that presses the band inner peripheral surface 72 against the bar outer peripheral surface 21 is maintained, and the rotation of the band portion 7 and the switch mounting portion 4 is permanent.

Further, the band portion 7 receives a pressing force applied by the booster mechanism of the wedge 81a by the anti-slip material 73 having a friction coefficient larger than that of the band inner peripheral surface 72, so that the frictional force is further increased. And the fixing force of the band part 7 becomes stronger.
Thus, the fixing force of the band portion 7 around the axis (X) of the handlebar 2 is improved, so that the force of the fingers operating the switch 44 causes the switch mounting portion 4 to move around the axis (X) of the handlebar 2. Even if it repeatedly acts in the direction in which it is rotated, the fixing force of the band portion 7 can be made permanent against the force. Other functions and effects are the same as those of the first embodiment.
In the second embodiment, the wedge portion 81 can be formed in a shape that is integral with the other band end portion 75 facing the split port 71 and can be bent instead of the support shaft 76.
The present invention is not limited to this embodiment, and can be applied to various hand switches for bicycles.

  The present invention can be used as a hand switch for various bicycles, and is particularly suitable as a hand switch for a bicycle for controlling an electric assist bicycle.
