Clamping device, electronic device arrangement and bicycle

Abstract

A fastening unit is provided which is designed to define a distance (W2) between a first adjustment section (33) and a second adjustment section (43) in the circumferential direction of a handlebar (4). A first engagement section (32) and a second engagement section (42) are arranged between a first holding section (72A) and a second holding section (72B) in the tangential direction of an outer circumferential surface of the handlebar (4). The fastening unit enables the adjustment of the distance (W2) between the first adjustment section (33) and the second adjustment section (43). A distance (W1) between the first engagement section (32) and the second engagement section (42) increases due to a reduction in the distance (W2) between the first adjustment section (33) and the second adjustment section (43).According to such a structure, it is possible to adjust a position of an electronic device (70) attached to the handlebar (4) and to facilitate the adjustment of the position.

Description

Background of the inventionField of the invention

[0001] The present disclosure relates to a clamping device, an electronic device assembly, and a bicycle. Description of the state of the art

[0002] A bicycle handlebar may be equipped with an electronic device that displays the vehicle speed, distance traveled, time, and the like. In JP 2544082 Y2, such an electronic device is detachable from a clamp (a component fastening device in JP 2544082 Y2) attached to a handlebar. As shown in JP 2015-085919 A, an electronic device attached to a handlebar of an electrically assisted bicycle may display an assist mode, remaining battery charge, and the like, and include a switch (button) for switching the assist mode.

[0003] In addition to the above-described electronic device that displays vehicle speed and the like, various parts and devices can be attached to a bicycle handlebar. For example, a clamp for holding a mobile phone, a lighting device, and the like can be attached to the handlebar. Therefore, the flexibility for positioning the clamp is limited, making it difficult to mount the electronic device in an optimal position. For example, a button might be located far from a grip.

[0004] An object of the present disclosure is to provide a clamping device that enables position adjustment of an electronic device and can effect easy adjustment of the position of the electronic device. Overview of the invention

[0005] (1) An example of a clamping device proposed in the present disclosure is a clamping device for attaching an electronic device having a first holding portion and a second holding portion to a handlebar.The clamping device has a first clamping element with a first inner peripheral surface extending along a portion of an outer peripheral surface of the handlebar, a first engagement portion engageable with the first holding portion to allow movement of the first holding portion in the longitudinal direction of the handlebar, and a first adjustment portion, a second clamping element with a second inner peripheral surface extending along another portion of the outer peripheral surface of the handlebar, a second engagement portion engageable with the second holding portion to allow movement of the second holding portion in the longitudinal direction of the handlebar, and a second adjustment portion, and a fixing unit configured to define a distance between the first adjustment portion and the second adjustment portion in the circumferential direction of the handlebar.The first engagement portion and the second engagement portion are located between the first holding portion and the second holding portion in the tangential direction of the outer peripheral surface of the handlebar. The fastening unit enables adjustment of the distance between the first adjustment portion and the second adjustment portion. A distance between the first engagement portion and the second engagement portion increases due to a decrease in the distance between the first adjustment portion and the second adjustment portion.

[0006] According to the clamping device, both the relative position between the clamping device and the handlebar and the relative position between the clamping device and the electronic device can be adjusted or fixed by operating the fixing unit. Therefore, the adjustment of the position can be facilitated.

[0007] (2) The clamp device according to (1) may further include a connecting shaft portion. The first clamp member and the second clamp member each include a first connecting portion and a second connecting portion disposed between the first engaging portion and the second engaging portion in the tangential direction of the outer peripheral surface of the handlebar. The connecting shaft portion connects the first connecting portion and the second connecting portion to enable the distance between the first engaging portion and the second engaging portion to be increased or decreased. Such a structure makes it possible to prevent separation of the two clamp members. This makes the clamp device easy to handle.

[0008] (3) In the clamp device according to (2), the connecting shaft portion protrudes from the first connecting portion in the longitudinal direction of the handlebar. A connecting hole into which the connecting shaft portion is fitted may be formed in the second connecting portion. The connecting hole may be larger than the connecting shaft portion in the tangential direction of the outer peripheral surface of the handlebar.

[0009] (4) In the clamp device according to (3), a distance between the connecting shaft portion and the outer peripheral surface of the handlebar may be smaller than a distance between the outer peripheral surface of the handlebar and a first plane passing through the first engaging portion and the second engaging portion, the first plane extending along a first tangent to the outer peripheral surface of the handlebar. Such an arrangement of the connecting shaft portion makes it possible to reduce the size of the connecting hole in the tangential direction of the outer peripheral surface of the handlebar. This can prevent a reduction in the strength of the second clamping member.

[0010] (5) In the clamping device according to any one of (1) to (4), the first adjustment portion, a contact surface between the first inner peripheral surface and the outer peripheral surface of the handlebar, and the first engagement portion function as a force point, a fulcrum, and a load point, respectively. The second adjustment portion, a contact surface between the second inner peripheral surface and the outer peripheral surface of the handlebar, and the second engagement portion function as a force point, a fulcrum, and a load point, respectively.

[0011] (6) In the clamping device according to any one of (1) to (5), the distance between the outer peripheral surface of the handlebar and the first plane passing through the first engaging portion and the second engaging portion may be greater than the distance between the outer peripheral surface of the handlebar and a second plane passing through the first adjusting portion and the second adjusting portion, the first plane passing along the first tangent to the outer peripheral surface of the handlebar and the second plane passing along a second tangent to the outer peripheral surface of the handlebar.Accordingly, when the positions of the two adjustment portions are fixed by the fixing unit, it is possible to prevent excessive force between the first engaging portion of the first clamping member and the first holding portion of the electronic device and excessive force between the second engaging portion of the second clamping member and the second holding portion of the electronic device.

[0012] (7) In the clamp device according to any one of (1) to (6), the distance between the first engaging portion and the second engaging portion in a first direction passing through the first engaging portion and the second engaging portion may be greater than the distance between the first adjusting portion and the second adjusting portion in a second direction passing through the first adjusting portion and the second adjusting portion, the first direction being along the first tangent to the outer peripheral surface of the handlebar, and the second direction being along the second tangent to the outer peripheral surface of the handlebar. Accordingly, the distance between the first engaging portion and the second engaging portion increases, thereby improving the stability of the clamp device in holding the electronic device.Since the distance between the first adjustment section and the second adjustment section decreases, the mounting unit can be prevented from protruding beyond the handlebar.

[0013] (8) In the clamp device according to any one of (1) to (7), when an angular position of an intermediate position between the first engaging portion and the second engaging portion is set to 0 degrees in the circumferential direction of the handlebar, at least one of the first adjusting portion and the second adjusting portion may be arranged in a range of 90 degrees to 270 degrees. Accordingly, it is possible to prevent a decrease in the strength of the first clamp member due to an excessive decrease in the distance between the first adjusting portion and the first engaging portion. It is possible to prevent a decrease in the strength of the second clamp member due to an excessive decrease in the distance between the second adjusting portion and the second engaging portion.

[0014] (9) In the clamp device according to any one of (1) to (8), when an angular position of an intermediate position between the first engaging portion and the second engaging portion is set to 0 degrees in the circumferential direction of the handlebar, an intermediate position between the first adjusting portion and the second adjusting portion can be in a range of 135 degrees to 225 degrees. Accordingly, the first clamping member and the second clamping member can have similar sizes. This can reduce a difference in the load acting on each of the two clamping members.

[0015] (10) In the clamp device according to any one of (1) to (9), the first plane passing through the first engagement portion and the second engagement portion may be substantially parallel to a direction in which the first adjustment portion and the second adjustment portion face each other, the first plane extending along the first tangent to the outer peripheral surface of the handlebar. Accordingly, the fixing unit can be operated from a front side or a rear side of the clamp device when the clamp device is attached to the handlebar. This can facilitate the position adjustment of the two adjustment portions by the fixing unit.

[0016] (11) In the clamp device according to any one of (1) to (9), the first plane passing through the first engaging portion and the second engaging portion may intersect with a direction in which the first adjusting portion and the second adjusting portion face each other, the first plane extending along the first tangent to the outer peripheral surface of the handlebar.

[0017] (12) An example of an electronic device assembly proposed in the present disclosure includes the clamping device according to any one of (1) to (11) and the electronic device.

[0018] (13) An example of a bicycle proposed in the present disclosure includes the clamping device according to any one of (1) to (11), the electronic device, and the handlebar.

[0019] The present disclosure is to be considered as illustrative of the invention and is not intended to limit the invention to the specific embodiments shown in the figures or the following description. The present invention will now be described with reference to the accompanying figures, which illustrate embodiments.

[0020] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention thereto. The term "and / or" as used herein includes all combinations of one or more of the associated listed elements. The singular forms "a," "an," and "the" as used herein are intended to include both the plural and singular forms unless the context clearly indicates otherwise. It is further understood that the terms "comprises," "has," "including," and / or "containing," when used in this specification, indicate the presence of the specified features, steps, acts, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, acts, elements, components, and / or groups thereof.

[0021] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art with respect to this invention. It is further understood that terms as defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0022] In describing the invention, it should be understood that several techniques are disclosed. Each of these techniques has individual utility and may also be used in conjunction with one or more, or in some cases, all, of the other disclosed techniques. For clarity, this description refrains from unnecessarily repeating every possible combination of the individual techniques. Nevertheless, the description and claims should be read with the understanding that such combinations are fully within the scope of the invention and the claims.

[0023] In the following description, numerous specific details are set forth for purposes of explanation in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without these specific details.

[0024] A clamping device and a bicycle proposed in the present disclosure are described below. Fig. 1 is a side view illustrating an example of the bicycle proposed in the present disclosure. Fig. 2 to 6B are views illustrating an example of the clamping device proposed in the present disclosure.

[0025] In the following description, a Y1 direction and a Y2 direction are used, which are Fig. 2 or the like are referred to as the front and rear, respectively. An X1 direction and an X2 direction shown in the drawing are referred to as the right side and left side, respectively, and a Z1 direction and a Z2 direction are referred to as the upper side and lower side, respectively. A Y1-Y2 direction is referred to as the forward-backward direction, and a Z1-Z2 direction is referred to as the up-down direction. An X1-X2 direction is referred to as the left-right direction or the longitudinal direction of a handlebar, as described below. Since the clamp device may be attached obliquely to a bicycle handlebar, the Fig. 2, the forward-backward direction (Y1-Y2 direction), the left-right direction (X1-X2 direction) and the up-down direction (Z1-Z2 direction) or the like may not entirely correspond to the forward-backward direction, the left-right direction and the up-down direction of the bicycle. [Bicycle]

[0026] As in Fig. 1, a bicycle 10 has a main frame 1, a front wheel 2, a rear wheel 3, a handlebar 4, a saddle 5, a crank 6 and a pedal 7. The bicycle 10 is an electrically assisted bicycle and may include a drive unit 8 and a battery 9 that supplies power to the drive unit 8.

[0027] As in Fig. As shown in Figure 1, the main frame 1 has a steering tube 11 at its front end. The steering tube 11 rotatably supports a steering shaft. The handlebar 4 is attached to an upper portion of the steering shaft. A grip 4a is provided at each of a right and a left end of the handlebar 4. A front fork 23, which rotatably supports the front wheel 2, is attached to a lower portion of the steering shaft.

[0028] As in Fig. 1, the main frame 1 may include, for example, an upper frame 12, a lower frame 13, a seat tube 14, a seat stay 15, a chainstay 16, and a bracket 17. The upper frame 12 extends obliquely rearward and downward from the head tube 11 and is connected at its rear end to the seat tube 14. The subframe 13 extends obliquely rearward and downward from the head tube 11 and is disposed below the upper frame 12. A rear end of the subframe 13 is connected to the bracket 17.

[0029] A seat post 21 extends upward from the seat tube 14 and supports the saddle 5 arranged above it. The bracket 17 is connected to a lower end of the seat tube 14. The seat stay 15 extends obliquely rearward and downward from the seat tube 14. The chainstay 16 extends rearward from the bracket 17. A lower end (rear end) of the seat stay 15 and a rear end of the chainstay 16 are connected. The rear wheel 3 is rotatably mounted in the space between them.

[0030] The crank 6 includes a crankshaft extending in the width direction of a bicycle frame and a crank arm 6a that rotates around the crankshaft. The pedal 7 is attached to a front end of the crank arm 6a. A chain 24 is tensioned between a sprocket provided on the crankshaft and a sprocket provided on an axle of the rear wheel 3.

[0031] The drive unit 8 includes an electric motor and a reduction mechanism and is held by the bracket 17. The drive unit 8 can transmit torque to the crank 6 and the sprocket. Therefore, a force acting on the pedal 7 (force from a rider stepping on the pedal 7) and a torque output from the drive unit 8 are transmitted to the rear wheel 3 via the chain 24.

[0032] The bicycle proposed in the present disclosure does not necessarily have to include the drive unit 8 described here. The structure of the main frame 1 is not necessarily limited to the Fig. 1. For example, the main frame 1 does not necessarily have to have the upper frame 12.

[0033] As in Fig. As shown in Figure 2, a clamping device 100 is attached to the handlebar 4. An electronic device 70 is held by the handlebar 4 by means of the clamping device 100.

[0034] As described below, the electronic device 70 is detachable from the clamping device 100. The clamping device 100 and the electronic device 70 form an electronic device assembly. [Electronic device or electronic device]

[0035] The electronic device 70 can be connected via a cable to a control device (not shown) or a sensor mounted on the bicycle 10. The electronic device 70 has a display device 71a and displays information received from the control device or the sensor, in particular information indicating the status of the bicycle 10, on the display device 71a. The information displayed on the display device 71a can be, for example, the vehicle speed, the distance traveled, the number of pedal revolutions, and the like. The electronic device 70 can display information related to the drive unit 8, such as the remaining charge of the battery 9 or an operating mode of the drive unit 8, as information indicating the status of the bicycle 10.The operating mode includes, for example, a power mode in which the torque output by the drive unit 8 is relatively large, a light mode in which the torque is relatively small, and a medium mode in which the torque is between the power mode and the light mode.

[0036] The control device mounted on the bicycle 10 can control the drive unit 8 based on an output signal from various sensors. Here, the information indicating the above-described status of the bicycle 10 can be transmitted from the control device to the electronic device 70. Alternatively, the output signal from the various sensors (e.g., a speed sensor or a pedaling force sensor) mounted on the bicycle 10 can be transmitted directly to the electronic device 70. Here, the electronic device 70 can output a signal for controlling the electric motor of the drive unit 8 (e.g., a current setpoint) to a drive circuit that supplies power to the electric motor based on the sensor output signal.

[0037] As in Fig. As shown in Figure 2, the electronic device 70 may include a plurality of buttons 74a and 74b. The buttons 74a and 74b may be provided on a front side of a main body 71 of the electronic device 70.

[0038] As in Fig. As shown in Figure 3, the electronic device 70 has a first engaged portion or holding portion 72A and a second engaged portion or holding portion 72B on one lower surface 71b thereof. The holding portions 72A and 72B protrude downward from the lower surface 71b of the electronic device 70. The two holding portions 72A and 72B are separated in the front-back direction and face each other. [Clamping device]

[0039] As in Fig. 4 and Fig. 5, the clamping device 100 has a first clamping element 30 and a second clamping element 40 which are assembled together.

[0040] The first clamping member 30 has a first inner peripheral surface 31a mounted along a portion of an outer peripheral surface of the handlebar 4. The second clamping member 40 has a second inner peripheral surface 41a mounted along another portion of the outer peripheral surface of the handlebar 4. The handlebar 4 may have a round cross-section. The inner peripheral surfaces 31a and 41a may be arcuate to be mounted along the outer peripheral surface of the handlebar 4.

[0041] The inner peripheral surfaces 31a and 41a are arranged to face each other and sandwich the outer peripheral surface of the handlebar 4 in the front-back direction. A diameter of the inner peripheral surfaces 31a and 41a and a diameter of the outer peripheral surface of the handlebar 4 do not necessarily have to be exactly the same. For example, a gap may be partially formed between the inner peripheral surfaces 31a and 41a and the outer peripheral surface of the handlebar 4.

[0042] As in Fig. As shown in Figure 5, the inner peripheral surface 41a of the second clamping element 40 may have an anti-slip layer 41b. Likewise, the inner peripheral surface 31a of the first clamping element 30 may have an anti-slip layer. [Engaging portion of the clamping element]

[0043] As in Fig. 4, the first clamping member 30 has a first engagement portion 32 engageable with the first holding portion 72A of the electronic device 70 at the top of the first clamping member 30. Similarly, the second clamping member 40 has a second engagement portion 42 engageable with the second holding portion 72B of the electronic device 70 at the top of the second clamping member 40.

[0044] As in Fig. 3, the two holding portions 72A and 72B of the electronic device 70 are formed so as to oppose each other in a tangential direction of the outer peripheral surface of the handlebar 4 (a direction of a tangent passing through an upper end of the outer peripheral surface; the Y1-Y2 direction in Fig. 3). The inner peripheral surfaces 31a and 41a of the clamping members 30 and 40 are curved to fit along the outer peripheral surface of the handlebar 4. Therefore, the "tangential direction of the outer peripheral surface of the handlebar 4" is also a tangential direction of a cylindrical surface formed by the inner peripheral surfaces 31a and 41a.

[0045] As in Fig. As shown in Fig. 6A, the engaging portions 32 and 42 of the clamping members 30 and 40 are arranged between the holding portions 72A and 72B of the electronic device 70 in the tangential direction of the outer peripheral surface of the handlebar 4 and engage with the holding portions 72A and 72B, respectively. Accordingly, the relative movement between the engaging portions 32 and 42 and the holding portions 72A and 72B in the tangential direction of the outer peripheral surface of the handlebar 4 is restricted. At the same time, relative movement between the holding portions 72A and 72B and the engaging portions 32 and 42 in the longitudinal direction of the handlebar 4 (the X1-X2 direction) is permitted.

[0046] As in Fig. 6B, the holding portions 72A and 72B of the electronic device 70 may be substantially L-shaped. The engaging portions 32 and 42 of the clamping device 100 may also be substantially L-shaped. The projections 32a and 42a of the engaging portions 32 and 42 may be fitted into the recessed portions 72c formed in the holding portions 72A and 72B. Accordingly, relative movement between the holding portions 72A and 72B and the engaging portions 32 and 42 is possible in the longitudinal direction of the handlebar 4. On the other hand, the relative movement between the same portions is restricted in the circumferential and tangential directions of the outer peripheral surface of the handlebar 4. [Adjustment section of the clamping element]

[0047] As in Fig. 6A, the first clamping member 30 has a first adjusting portion 33 at a lower portion thereof. The second clamping member 40 has a second adjusting portion 43 at a lower portion thereof. The two adjusting portions 33 and 43 face each other in the tangential direction of the outer peripheral surface of the handlebar 4 (a direction of the tangent passing through the lower end of the outer peripheral surface, the Y1-Y2 direction in Fig. 6A).

[0048] The clamping device 100 has a fastening unit which defines a distance W2 between the adjustment sections 33 and 43 (see Fig. 6A). The clamping device 100 may, for example, comprise a screw 51 and a nut 52 as a fastening unit. The nut 52 is held by the second adjusting portion 43. A hole 33c is formed on the first adjusting portion 33, into which the screw 51 is inserted (see Fig. 4). The screw 51 is inserted into the hole 33c from a rear side of the first adjustment section 33 (a side opposite the second adjustment section 43) and fastened to the nut 52. This sets the distance W2 between the adjustment sections 33 and 43.

[0049] When the second clamping member 40 is molded from resin, the nut 52 may be retained in the second adjustment portion 43 by insert molding. Alternatively, a receiving recess portion may be formed in the second adjustment portion 43, and the nut 52 may be inserted into the receiving recess portion. [Movement of the clamping element due to the actuation of the fastening unit]

[0050] When the screw 51 is tightened, the distance W2 between the adjustment sections 33 and 43 decreases (see 6A). Conversely, the distance W2 between the adjustment sections 33 and 43 may increase when the screw 51 is loosened. The distance W1 between the first engagement section 32 and the second engagement section 42 (see Fig. 6A) in the tangential direction of the outer peripheral surface of the handlebar 4 (a direction of the tangent passing through the upper end of the outer peripheral surface) can be decreased or increased.

[0051] As in Fig. As shown in FIG. 6A, the distance W1 between the first engaging portion 32 and the second engaging portion 42 increases due to a decrease in the distance W2 between the adjusting portions 33 and 43 when the inner peripheral surfaces 31a and 41a sandwich the handlebar 4. As a result, the first engaging portion 32 and the second engaging portion 42 are pressed against the first holding portion 72A and the second holding portion 72B of the electronic device 70, respectively. A contact force (frictional force) between the engaging portions 32 and 42 and the holding portions 72A and 72B becomes large, and the relative position of the clamp device 100 and the electronic device 70 in the longitudinal direction of the handlebar 4 is thus fixed. As the distance W2 of the adjusting portions 33 and 43 decreases, a contact force between the inner peripheral surfaces 31a and 41a and the outer peripheral surface of the handlebar 4 increases.Therefore, the position of the clamping device 100 on the handlebar 4 is also fixed.

[0052] Conversely, increasing the distance W2 between the adjustment portions 33 and 43 allows for a reduction in the distance W1 between the first engagement portion 32 and the second engagement portion 42. Accordingly, the contact force between the first engagement portion 32 and the first holding portion 72A and the contact force between the second engagement portion 42 and the second holding portion 72B are reduced, allowing the relative position of the clamping device 100 and the electronic device 70 to change in the longitudinal direction of the handlebar 4. In addition, the contact force between the inner peripheral surfaces 31a and 41a and the outer peripheral surface of the handlebar 4 is reduced. Accordingly, positional adjustment of the clamping device 100 on the handlebar 4 is possible.

[0053] By using the clamping device 100, it is thus possible to adjust both the relative position of the clamping device 100 and the electronic device 70 and the position of the clamping device 100 on the handlebar 4 simply by operating a single fastening unit (the screw 51).

[0054] The first clamping member 30 and the second clamping member 40 are connected to each other only via a connecting shaft portion 53, which will be described below, and are not connected to each other in any other portion. Therefore, when the distance W2 of the adjusting portions 33 and 43 is decreased or increased, the distance W1 of the engaging portions 32 and 42 is increased or decreased accordingly. [Size of the clamping device]

[0055] As in Fig. As shown in Figure 3, the holding portions 72A and 72B of the electronic device 70 extend in the longitudinal direction of the handlebar 4 (the X1-X2 direction). The size of the holding portions 72A and 72B in the longitudinal direction of the handlebar 4 (X1-X2 direction) differs from the size of the clamping members 30 and 40 in the same direction. Specifically, the size of the holding portions 72A and 72B of the electronic device 70 is larger than the size of the clamping members 30 and 40 in the same direction. The engaging portions 32 and 42 are relatively slidable along the holding portions 72A and 72B. The relative position of the electronic device 70 and the clamping device 100 can be adjusted within a range of the holding portions 72A and 72B.

[0056] As in Fig. As shown in Figure 3, the electronic device 70 has an operating unit 73 on the left side. The operating unit 73 extends downward from the main body 71. The operating unit 73 is provided with a switch 73a. The switch 73a can, for example, be a switch for switching the operating mode of the drive unit 8 (power mode, medium mode, light mode). The switch 73a can also be an on / off switch for a lighting device.

[0057] The holding portions 72A and 72B are formed on the lower surface 71b of the main body 71 closer to the left side. That is, the holding portions 72A and 72B are formed closer to the operation unit 73. The centers of the holding portions 72A and 72B in the left-right direction (the longitudinal direction of the handlebar 4) are located to the left of a center of the main body 71 of the electronic device 70 in the left-right direction. Such holding portions 72A and 72B can prevent the clamp device 100 from holding the right portion of the main body 71 (a position far from the operation unit 73). This can prevent, for example, the support of the electronic device 70 from becoming unstable when the operation unit 73 is pressed.

[0058] When the screw 51 is tightened, a force is applied from the fastening unit (the screw 51) to the first adjustment portion 33, and the first adjustment portion 33 is moved forward (in the Y1 direction). At this time, the inner peripheral surface 31a is pressed against the outer peripheral surface of the handlebar 4. The first engagement portion 32 is moved in a direction opposite to the first adjustment portion 33, that is, backward (in the Y2 direction), and is pressed against the first holding portion 72A of the electronic device 70. In other words, during these movements, the first adjustment portion 33, the contact surface between the inner peripheral surface 31a and the outer peripheral surface of the handlebar 4, and the first engagement portion 32 function as the force point, the fulcrum, and the load point, respectively.

[0059] When the screw 51 is tightened, a force is applied from the fastening unit (the nut 52) ​​to the second adjustment portion 43, and the second adjustment portion 43 is moved rearward (in the Y2 direction). At this time, the inner peripheral surface 41a is pressed against the outer peripheral surface of the handlebar 4. The second engagement portion 42 is moved in a direction opposite to the second adjustment portion 43, that is, forward (in the Y1 direction), and is pressed against the second holding portion 72B of the electronic device 70. In other words, during these movements, the second adjustment portion 43, the contact surface between the inner peripheral surface 41a and the outer peripheral surface of the handlebar 4, and the second engagement portion 42 function as the force point, the fulcrum point, and the load point, respectively. [Details of the setup for the intervention]

[0060] As in Fig. As shown in Fig. 6B, a rear surface 32b (the surface facing in the Y2 direction) of a base of the first engaging portion 32 is pressed against a tip of a protruding portion 72e of the first holding portion 72A. A base of a lower surface 32c of the protruding portion 32a of the first engaging portion 32 is also pressed against the tip of the protruding portion 72e of the first holding portion 72A. An upper surface 32d of the first engaging portion 32 (an upper surface of the first clamping member 30) is pressed against the lower surface 71b of the electronic device 70.

[0061] Similarly, a front surface 42b (a surface facing the Y1 direction) of a base of the second engaging portion 42 is pressed against a tip of the protruding portion 72e of the second holding portion 72B. A base of a lower surface 42c of the protruding portion 42a of the second engaging portion 42 is also pressed against the tip of the protruding portion 72e of the second holding portion 72B. An upper surface 42d of the second engaging portion 42 (an upper surface of the second clamping member 40) is pressed against the lower surface 71b of the electronic device 70.

[0062] With such a structure, the clamping elements 30 and 40 are reduced when the distance W2 between the adjusting sections 33 and 43 (see Fig. 6A) is rotated along the outer peripheral surface of the link 4, so that the distance W1 between the two engaging portions 32 and 42 increases. This increases the contact force at each of the above-described portions. In particular, between the engaging portions 32 and 42 and the holding portions 72A and 72B, not only the contact force in the front-to-back direction increases, but also the contact force in the top-to-bottom direction increases. The contact force in the up-down direction is specifically the contact force between the upper surfaces 32d and 42d of the engaging portions 32 and 42 and the lower surface 71b of the electronic device 70, and the contact force between the lower surfaces 32c and 42c of the engaging portions 32 and 42 and the holding portions 72A and 72B.Accordingly, the relative position of the electronic device 70 with respect to the clamping device 100 is fixed in the forward-backward direction, the up-down direction, and the left-right direction.

[0063] As in Fig. 6B, the upper surfaces 32d and 42d of the engaging portions 32 and 42, respectively, have inclined surfaces 32e and 42e. The inclined surfaces 32e and 42e are gradually lowered toward the tips of the projecting portions 32a and 42a. As the distance W2 between the adjusting portions 33 and 43 increases, the clamping members 30 and 40 are rotated along the outer peripheral surface of the handlebar 4, so that the distance W1 between the two engaging portions 32 and 42 decreases. Therefore, the engaging portions 32 and 42 are separated from the projecting portions 72e of the holding portions 72A and 72B. Here, the inclined surfaces 32e and 42e point straight upward (ie, the inclined surfaces 32e and 42e come into contact with the lower surface 71b of the main body 71).Accordingly, the contact force between the engaging portions 32 and 42 and the lower surface 71b of the main body 71 decreases, making it possible to move the electronic device 70 in the left-right direction relative to the clamping device 100. The clamping device 100 itself can also be moved in the left-right direction.

[0064] The clamping elements 30 and 40 can each be molded as a unit from resin. Here, the clamping elements 30 and 40 can be easily elastically deformed when the screw 51 is tightened. This can prevent the engagement between the engaging portions 32 and 42 and the holding portions 72A and 72B from becoming loose, for example, due to vibrations of the bicycle 10. Alternatively, the clamping elements 30 and 40 can be made of metal. [Connecting section of the clamping element and connecting shaft section]

[0065] As in Fig. As shown in Figure 5, the first clamping element 30 and the second clamping element 40 each have a first connecting portion 34 and a second connecting portion 44. The connecting portions 34 and 44 are located between the two engagement portions 32 and 42.

[0066] In detail, in a plan view of the clamping device 100, the connecting portions 34 and 44 are arranged between the engaging portions 32 and 42. In a side view of the clamping device 100, the engaging portions 32 and 42 and the connecting portions 34 and 44 are arranged in the same direction with respect to the outer peripheral surface of the handlebar 4. In detail, a plane P1 (see Fig. 6A), which passes through the engaging portions 32 and 42 and extends along a tangent to the outer peripheral surface of the handlebar 4, above the outer peripheral surface of the handlebar 4. Similar to the engaging portions 32 and 42, the connecting portions 34 and 44 are located above the outer peripheral surface of the handlebar 4.

[0067] As in Fig. 4 and Fig. 5, the two connected sections 34 and 44 are assembled accordingly. In detail, a recess section 44b (see Fig. 5) may be formed in the second connecting portion 44. The first connecting portion 34 may be fitted into the recess portion 44b. The second connecting portion 44 may have two sidewall portions 44c. The recess portion 44b may be formed between the two sidewall portions 44c. In a side view of the clamping device 100, the first connecting portion 34 overlaps the sidewall portion 44c of the second connecting portion 44.

[0068] The clamping device 100 has the connecting shaft section 53 (see Fig. 4) that connects the connecting sections 34 and 44 to each other. The connecting shaft section 53 is inserted into the connecting sections 34 and 44 in the longitudinal direction of the handlebar 4. The connecting shaft section 53 can prevent the two clamping elements 30 and 40 from being separated from each other. Therefore, for example, the attachment of the clamping device 100 to the handlebar 4 can be facilitated.

[0069] The first clamping member 30 and the second clamping member 40 can move around the connecting shaft portion 53, so that the distance W2 between the first adjustment portion 33 and the second adjustment portion 43 can be increased or decreased. The clamping members 30 and 40 can be opened so that the distance W2 of the adjustment portions 33 and 43 is larger than a diameter of the outer peripheral surface of the handlebar 4. Accordingly, it is possible to further facilitate the attachment of the clamping device 100 to the handlebar 4.

[0070] A hole 34a is formed through the first connecting portion 34. The connecting shaft portion 53 is inserted into the hole 34a. Both ends of the connecting shaft portion 53 protrude from the first connecting portion 34 in the longitudinal direction of the handlebar 4. A connecting hole 44a is formed through the side wall portion 44c of the second connecting portion 44. The connecting shaft portion 53 is inserted into the connecting hole 44a.

[0071] The relative position of the first connecting portion 34 and the connecting shaft portion 53 is fixed. In other words, the connecting shaft portion 53 is held by the first connecting portion 34. The connecting shaft portion 53 can be press-fitted into the hole 34a of the first connecting portion 34. The size of the connecting hole 44a of the second connecting portion 44 is larger than the size of the connecting shaft portion 53. More specifically, a width of the connecting hole 44a in a direction extending along a tangent to the outer peripheral surface of the handlebar 4 (a tangent passing through the upper end of the outer peripheral surface) and through the engaging portions 32 and 42 (a direction extending along the plane P1 in Fig. 6A) is larger than that of the connecting shaft portion 53.

[0072] As a result, the connecting shaft portion 53 connects the connecting portions 34 and 44 and allows a change in the distance W1 between the first engaging portion 32 and the second engaging portion 42. In a Fig. In the example shown in Fig. 5 and the like, the connecting hole 44a is an elongated hole extending in a direction passing through the engaging portions 32 and 42. However, the connecting hole 44a may be circular or elliptical.

[0073] The connecting shaft portion 53 is a member formed separately from the first clamping member 30 and can be inserted into the holes 34a and 44a of the two connecting portions 34 and 44 after the two connecting portions 34 and 44 have been assembled. [Position of the connecting shaft section]

[0074] In Fig. 6A, the plane P1 is a plane extending along a tangent to the outer peripheral surface of the link 4 (a plane passing through the upper end of the outer peripheral surface) and passing through the two engaging portions 32 and 42. More specifically, the plane P1 is a plane passing through the protrusion portions 32a and 42a of the engaging portions 32 and 42. In Fig. 6A, a plane P3 is a plane parallel to the plane P1 passing through the connecting shaft portion 53.

[0075] As in Fig. As shown in FIG. 6A, a distance L3 from the outer peripheral surface of the link 4 to the plane P3 is smaller than a distance L1 from the outer peripheral surface of the link 4 to the plane P1. By disposing the connecting shaft portion 53 in this way, the distance between the outer peripheral surface of the link 4 and the connecting shaft portion 53 is small, so that a change in the relative position of the connecting shaft portion 53 and the connecting hole 44a of the second connecting portion 44 can be reduced. Therefore, the connecting hole 44a with a short length is sufficient, making it easy to ensure the strength of the second connecting portion 44. [Positional relationship between engagement section and adjustment section]

[0076] In Fig. 6A, a plane P2 is a plane extending along a tangent to the outer peripheral surface of the handlebar 4 (a tangent passing through the lower end of the outer peripheral surface) and passing through the two adjusting portions 33 and 43. More specifically, the plane P2 is a plane passing through the centers of the adjusting portions 33 and 43 (centers of the bolt 51 and the nut 52).

[0077] The distance L1 from the outer peripheral surface of the handlebar 4 to the plane P1 is greater than the distance L2 from the outer peripheral surface of the handlebar 4 to the plane P2. Due to this structure, the position of the electronic device 70 is far away from the handlebar 4, so that interference between the electronic device 70 and other parts attached to the handlebar 4 can be easily avoided. When the screw 51 is firmly tightened, excessive force can be prevented from acting between the engaging portions 32 and 42 of the clamping members 30 and 40 and the holding portions 72A and 72B of the electronic device 70. This can prevent, for example, plastic deformation of the clamping members 30 and 40. Note that, unlike the example shown in FIG. 6A, the distance L1 from the outer peripheral surface of the handlebar 4 to the plane P1 may be smaller than the distance L2 from the outer peripheral surface of the handlebar 4 to the plane P2.

[0078] As shown in Fig. 6A, the distance W1 between the first engagement portion 32 and the second engagement portion 42 is greater than the distance W2 between the first adjustment portion 33 and the second adjustment portion 43. It is preferable that the distance W1 between the first engagement portion 32 and the second engagement portion 42 is greater than the diameter of the outer peripheral surface of the handlebar 4. Accordingly, the distance W1 becomes greater, and the holding stability for the electronic device 70 by the clamp device 100 can be improved. At the same time, it is preferable that the distance W2 between the first adjustment portion 33 and the second adjustment portion 43 is smaller than the diameter of the outer peripheral surface of the handlebar 4. Accordingly, the fastening unit (the bolt 51 and the nut 52) ​​can be prevented from protruding due to the handlebar 4.

[0079] As in Fig. 6A, a line B1 is a line passing through an axis Ax of the handlebar 4 and an intermediate position between the first engaging portion 32 and the second engaging portion 42. When an angular position of the line B1 in the circumferential direction of the handlebar 4 is set to 0 degrees, it is preferable that at least one of the two adjusting portions 33 and 43 is within a range of 90 degrees to 270 degrees. In other words, it is preferable that at least one of the two adjusting portions 33 and 43 is located between a line B2 (a line indicating a position of 90 degrees) and a line B3 (a line indicating a position of 270 degrees) in the circumferential direction of the handlebar 4.

[0080] As in Fig. 6A, it is preferable that at least one of the two adjusting portions 33 and 43 be disposed within a range of 135 degrees to 225 degrees. In other words, it is preferable that at least one of the two adjusting portions 33 and 43 be disposed between a line B4 (a line indicating a position of 135 degrees) and a line B5 (a line indicating a position of 225 degrees) in the circumferential direction of the handlebar 4. According to such a structure, the two clamp members 30 and 40 can have similar sizes. Thereby, a difference in the load acting on the two clamp members 30 and 40 can be reduced.

[0081] In the Fig. In the example shown in Fig. 6A, the two adjusting portions 33 and 43 and the fastening unit (the bolt 51 and the nut 52) ​​are located in the range of 135 degrees (the line B4) to 225 degrees (the line B5). An intermediate position of the adjusting portions 33 and 43 is located on the opposite side of the intermediate position of the engaging portions 32, 42, with the axis Ax of the handlebar 4 therebetween. Thus, the engaging portions 32 and 42, to which a large force is applied, are separated from the hole 33c for inserting the bolt 51 formed in the first adjusting portion 33 and an inner gap of the second adjusting portion 43 in which the nut 52 is disposed. Therefore, it is possible to prevent a reduction in the strength of the engaging portions 32 and 42 (rigidity of the resin around the engaging portions 32 and 42) caused by the hole 33c and the gap for the nut 52 located nearby there.

[0082] As in Fig. As shown in Fig. 6A, the above-described plane P1 passing through the first engagement portion 32 and the second engagement portion 42 and a direction in which the first adjustment portion 33 and the second adjustment portion 43 face each other (insertion direction of the screw 51) may be substantially parallel. According to such a structure, the screw 51 can be easily seen when tightening the fastening unit (in particular, the screw 51), thus facilitating tightening. For example, a head of the screw 51 is exposed to the rear, facilitating tightening of the screw 51. Here, "substantially parallel" also includes cases where the plane P1 and the direction in which the adjustment portions 33 and 43 face each other are not completely parallel, but are inclined, for example, in a range of 0 degrees to 10 degrees. [Another example of a clamping device]

[0083] Fig. 7 and Fig. 8 are diagrams illustrating a modified example of the clamping device proposed in the present disclosure. The following description focuses on the differences between a Fig. 7 and Fig. 8 shown clamping device 200 and the one in Fig. 2 to 6B. Aspects not described with respect to the clamping device 200 may be similar to those of the clamping device 100.

[0084] As in Fig. As shown in Figure 7, the clamping device 200 includes a first clamping element 230 and a second clamping element 240. The first clamping element 230 includes a first engagement portion 232, an inner peripheral surface 231a formed along the outer peripheral surface of the handlebar 4, a first adjustment portion 233, and a first connecting portion 234. The second clamping element 240 includes a second engagement portion 242, an inner peripheral surface 241a formed along the outer peripheral surface of the handlebar 4, a second adjustment portion 243, and a second connecting portion 244.

[0085] As in Fig. 8, the inner peripheral surface 231a of the first clamping element 230 is shaped to cover only approximately 1 / 4 of the outer peripheral surface of the handlebar 4. The first adjustment portion 233 is located below the first engagement portion 232. In a plan view of the clamping device 200, a projection 232a of the first engagement portion 232 overlaps the first adjustment portion 233. The inner peripheral surface 241a of the second clamping element 240 surrounds approximately 3 / 4 of the outer peripheral surface of the handlebar 4. The second adjustment portion 243 is located below the first adjustment portion 233.

[0086] As in Fig. 8, the first engagement portion 232 and the second engagement portion 242 are in the forward-backward direction (in Fig. 8 the Y1-Y2 direction) are arranged at a distance from each other. The first adjusting section 233 and the second adjusting section 243 are arranged in the up-down direction (the Z1-Z2 direction in Fig. 8) in contrast to the Fig. 2 or the like. In other words, a plane P1 extending along a tangent to the outer peripheral surface of the handlebar 4 and passing through the first engagement portion 232 and the second engagement portion 242 intersects a direction in which the adjustment portions 233 and 243 face each other. More specifically, the plane P1 and the direction in which the adjustment portions 233 and 243 face each other may be substantially perpendicular to each other. "Substantially perpendicular" includes not only the case where the angle between the plane P1 and the direction in which the adjustment portions 233 and 243 face each other is 90 degrees, but also the case where the angle is, for example, 85 degrees to 95 degrees.

[0087] The clamping device 200 has a fixing unit that defines a distance W2 between the adjusting sections 233 and 243 (see Fig. 8). The clamp device 200 may include the bolt 51 and the nut 52 as a fastening unit. The nut 52 may be held by the first adjusting portion 233. A hole into which the bolt 51 is inserted may be formed in the second adjusting portion 243. The bolt 51 is inserted into the hole from a lower side (a side opposite to the first adjusting portion 233) of the second adjusting portion 243 and fastened to the nut 52. This sets the distance W2 between the adjusting portions 233 and 243. According to such a fastening unit, for example, during tightening of the bolt 51, it is possible to prevent other parts and devices attached to the handlebar 4 from interfering with the fastening operation.

[0088] One in Fig. Line B1 shown in Figure 8 is similar to that shown in Fig. 6A, line B1 is a line passing through the axis Ax of the handlebar 4 and an intermediate position between the first engagement portion 232 and the second engagement portion 242. When an angular position of line B1 in the circumferential direction of the handlebar 4 is set to 0 degrees, the second adjustment portion 243 of the two adjustment portions 233 and 243 is located in a range of 90 degrees to 270 degrees. That is, the second adjustment portion 243 is located between a line B2 (line indicating a position of 90 degrees) and a line B3 (line indicating a position of 270 degrees) in the circumferential direction of the handlebar 4. The first adjustment portion 233 is located in a range of more than 270 degrees (the line B3).

[0089] As in Fig. 7, a recessed portion 231c is formed between the projection portion 232a of the first engagement portion 232 and the first adjustment portion 233. A projection portion of the first holding portion 72A of the electronic device 70 is fitted into the recessed portion 231c. The nut 52 is located below the recessed portion 231c. In the embodiment shown in Fig. 6A, such a recessed section is not necessary since the first adjustment section 233 is located below the handlebar 4.

[0090] The movements of the first clamping element 230 and the second clamping element 240 are similar to the movements of the clamping elements 30 and 40 of the clamping device 100 described above.

[0091] That is, when the screw 51 is tightened, the distance W2 between the adjustment sections 233 and 243 decreases (see Fig. 8). Conversely, the distance W2 between the adjustment portions 233 and 243 may increase when the screw 51 is loosened. The distance W1 between the first engagement portion 232 and the second engagement portion 242 (see Fig. 8) in the tangential direction of the outer peripheral surface of the handlebar 4 can increase or decrease.

[0092] When the inner peripheral surfaces 231a and 241a sandwich the handlebar 4, the distance W1 between the first engaging portion 232 and the second engaging portion 242 increases due to a decrease in the distance W2 between the adjusting portions 233 and 243. Accordingly, a contact force between the inner peripheral surfaces 231a and 241a and the outer peripheral surface of the handlebar 4 increases. Therefore, a position of the clamping device 200 on the handlebar 4 is fixed. A relative position of the clamping device 200 and the electronic device 70 in the longitudinal direction of the handlebar 4 is fixed.

[0093] Conversely, increasing the distance W2 between the adjustment portions 233 and 243 allows for decreasing the distance W1 between the first engagement portion 232 and the second engagement portion 242. Accordingly, a contact force between the first engagement portion 232 and the first holding portion 72A and a contact force between the second engagement portion 242 and the second holding portion 72B are weakened. This allows the relative position of the clamp device 200 and the electronic device 70 to be changed in the longitudinal direction of the handlebar 4. The contact force between the inner peripheral surfaces 231a and 241a and the outer peripheral surface of the handlebar 4 also decreases. Therefore, it is also possible to adjust the position of the clamp device 200 in the longitudinal direction of the handlebar 4.

[0094] The first clamping member 230 and the second clamping member 240 are connected to each other only via the connecting shaft portion 53 and are not connected to each other in any other portion. Therefore, when the distance W2 between the adjusting portions 233 and 243 decreases or increases, the distance W1 between the engaging portions 232 and 242 increases or decreases accordingly. [Summary]

[0095] (1) Clamp devices 100 and 200 proposed in the present disclosure are for attaching an electronic device 70, which has a first holding portion 72A and a second holding portion 72B, to a handlebar 4. The clamp devices 100 and 200 have a first clamping member 30 or 230 having a first inner peripheral surface 31a or 231a extending along a portion of an outer peripheral surface of the handlebar 4, a first engagement portion 32 or 232 engageable with the first holding portion 72A to allow movement of the first holding portion 72A in a longitudinal direction of the handlebar 4, and a first adjustment portion 33 or 233, a second clamping member 40 or 240 having a second peripheral surface 41a extending along another portion of the outer peripheral surface of the handlebar 4, a second engagement section 42 or 242,which can be engaged with the second holding portion 72B to enable movement of the second holding portion 72B in the longitudinal direction of the handlebar 4, and a second adjusting portion 43 or 243, and a fastening unit which is designed so thatthat it defines a distance between the first adjustment portion 33 or 233 and the second adjustment portion 43 or 243 in a circumferential direction of the handlebar 4. The first engagement portion 32 or 232 and the second engagement portion 42 or 242 are arranged between the first holding portion 72A and the second holding portion 72B in a tangential direction of the outer peripheral surface of the handlebar 4. The fastening unit enables the adjustment of a distance W2 between the first adjustment portion 33 or 233 and the second adjustment portion 43 or 243. A distance W1 between the first engagement portion 32 or 232 and the second engagement portion 42 or 242 increases due to a decrease in the distance W2 between the first adjustment portion 33 or 233 and the second adjustment portion 43 or 243.

[0096] According to the clamp devices 100 and 200, both (a) a relative position of the clamp device and the handlebar 4 and (b) a relative position of the clamp device and the electronic device 70 can be adjusted or fixed by operating the fixing unit. Therefore, position adjustment can be facilitated.

[0097] (2) The clamp devices 100 and 200 according to (1) may further include a connecting shaft portion 53. The first clamp member 30 or 230 and the second clamp member 40 or 240 each include a first connecting portion 34 or 234 and a second connecting portion 44 or 244 disposed between the first engaging portion 32 or 232 and the second engaging portion 42 or 242 in the tangential direction of the outer peripheral surface of the handlebar 4. The connecting shaft portion 53 connects the first connecting portion 34 or 234 and the second connecting portion 44 or 244 to enable the distance W1 between the first engaging portion 32 or 232 and the second engaging portion 42 or 242 to be increased or decreased. Such a structure makes it possible to prevent the two clamp members 30 and 40 from separating. This makes the clamping devices 100 and 200 easy to handle.

[0098] (3) In the clamp device 100 or 200 according to (2), the connecting shaft portion 53 protrudes from the first connecting portion 34 or 234 in the longitudinal direction of the handlebar 4. A connecting hole 44a into which the connecting shaft portion 53 is fitted may be formed in the second connecting portion 44 or 244. The connecting hole 44a may be larger than the connecting shaft portion 53 in the tangential direction of the outer peripheral surface of the handlebar 4.

[0099] (4) In the clamp devices 100 and 200 according to (3), a distance L3 between the connecting shaft portion 53 and the outer peripheral surface of the handlebar 4 may be smaller than a distance L1 between the outer peripheral surface of the handlebar 4 and a plane P1 passing through the first engaging portion 32 or 232 and the second engaging portion 42 or 242, the plane P1 extending along a first tangent to the outer peripheral surface of the handlebar 4. Such an arrangement of the connecting shaft portion 53 makes it possible to reduce the size of the connecting hole 44a in the tangential direction of the outer peripheral surface of the handlebar 4. Thereby, a reduction in the strength of the second clamp member 40 or 240 due to the connecting hole 44a can be prevented.

[0100] (5) In the clamp device 100, 200 according to any one of (1) to (4), the first adjustment portion 33, 233, a contact surface between the first inner peripheral surface 31a, 231a and the outer peripheral surface of the handlebar 4, and the first engagement portion 32, 232 function as a force point, a fulcrum, and a load point, respectively. The second adjustment portion 43, 243, a contact surface between the second inner peripheral surface 41a and the outer peripheral surface of the handlebar 4, and the second engagement portion 42, 242 function as a force point, a fulcrum, and a load point, respectively.

[0101] (6) In the clamp devices 100 and 200 according to any one of (1) to (5), the distance L1 between the outer peripheral surface of the handlebar 4 and the plane P1 passing through the first engaging portion 32 or 232 and the second engaging portion 42 or 242 may be greater than a distance L2 between the outer peripheral surface of the handlebar 4 and a plane P2 passing through the first adjusting portion 33 or 233 and the second adjusting portion 43 or 243, the plane P1 passing along the first tangent to the outer peripheral surface of the handlebar 4 and the plane P2 passing along a second tangent to the outer peripheral surface of the handlebar 4.Therefore, when the positions of the two adjustment portions 33 and 43 or 233 and 243 are fixed by the fixing unit, an excessive force can be prevented from acting between the first engaging portion 32 or 232 of the first clamping member 30 or 230 and the first holding portion 72A of the electronic device 70, and an excessive force can be prevented from acting between the second engaging portion 42 or 242 of the second clamping member 40 or 240 and the second holding portion 72B of the electronic device 70.

[0102] (7) In the clamp devices 100 and 200 according to any one of (1) to (6), the distance W1 between the first engaging portion 32 or 232 and the second engaging portion 42 or 242 in a first direction passing through the first engaging portion 32 or 232 and the second engaging portion 42 or 242 may be greater than the distance W2 between the first adjusting portion 33 or 233 and the second adjusting portion 43 or 243 in a second direction passing through the first adjusting portion 33 or 233 and the second adjusting portion 43 or 243, the first direction being along the first tangent to the outer peripheral surface of the handlebar 4 and the second direction being along the second tangent to the outer peripheral surface of the handlebar 4.Accordingly, the distance W1 between the first engaging portion 32 or 232 and the second engaging portion 42 or 242 increases, thereby improving the stability of the clamping devices 100 and 200 in holding the electronic device 70. Since the distance W2 between the first adjusting portion 33 or 233 and the second adjusting portion 43 or 243 decreases, the fastening unit (the bolt 51 and the nut 52) ​​can be prevented from protruding.

[0103] (8) In the clamp devices 100 and 200 according to any one of (1) to (7), when an angular position of an intermediate position between the first engaging portion 32 or 232 and the second engaging portion 42 or 242 is set to 0 degrees in the circumferential direction of the handlebar 4, the first adjusting portion 33 or 233 and / or the second adjusting portion 43 or 243 can be arranged in a range of 90 degrees to 270 degrees. Accordingly, it is possible to prevent a reduction in the strength of the first clamp member 30 or 230 due to an excessive reduction in the distance between the first adjusting portion 33 or 233 and the first engaging portion 32 or 232. It is possible to prevent a reduction in the strength of the second clamping member 40 or 240 due to an excessive reduction in the distance between the second adjusting portion 43 or 243 and the second engaging portion 42 or 242.

Accordingly, the first clamp member 30 and the second clamp member 40 can have similar sizes. This can reduce a difference in the load acting on each of the two clamp members 30 and 40.

[0105] (10) In the clamp device 100 according to any one of (1) to (9), the plane P1 passing through the first engaging portion 32 and the second engaging portion 42 may be substantially parallel to a direction in which the first adjusting portion 33 and the second adjusting portion 43 face each other, and the plane P1 may extend along the first tangent to the outer peripheral surface of the handlebar 4. Accordingly, the fixing unit can be operated from a front side or a rear side of the clamp device 100 when the clamp device 100 is attached to the handlebar 4. Therefore, the fixing unit can facilitate the positional adjustment of the two adjusting portions 33 and 43.

[0106] (11) In the clamp device 200 according to any one of (1) to (9), the plane P1 passing through the first engaging portion 232 and the second engaging portion 242 may intersect a direction in which the first adjusting portion 233 and the second adjusting portion 243 face each other, the plane P1 passing along the first tangent to the outer peripheral surface of the handlebar 4.

[0107] (12) An electronic device assembly proposed in the present disclosure includes the clamping device 100, 200 according to any one of (1) to (11) and the electronic device 70.

[0108] (13) A bicycle 10 proposed in the present disclosure includes the clamping device 100, 200 according to any one of (1) to (11), the electronic device 70, and the handlebar 4. [Miscellaneous]

[0109] The fastening unit is not limited to the screw 51 and the nut 52, as long as the fastening unit enables the fixation and adjustment of the distance W2 between the adjustment sections 33 and 43. The fastening unit may be a screw, a lever screw (clamping lever), a cam lever, or the like.
