Description

  The present invention relates to a device for stabilizing driving during a push operation of a two-wheeled vehicle and a three-wheeled vehicle. In particular, the present invention relates to an auxiliary control device that realizes that a two-wheeled vehicle can be operated in a straight posture on walking or in a crowded sidewalk in a city by a method that enables safer and more stable operation during hand-held operation.

  When walking by pushing a two-wheeled vehicle or a three-wheeled vehicle, it is common to push the center of the steering wheel with a hand and to steer with both hands. At this time, when walking with both hands on the handle, it becomes a difficult posture by twisting the body.

  Also, when walking while holding the center of the steering wheel, the direction is likely to change greatly with a slight movement of the steering wheel, and many nerves are used for stable walking. Until now, there has been no idea how to maneuver while walking without burdening the body.

  The present invention is a hand-operated two-wheeled and three-wheeled vehicle. If you want to walk for health while cycling, or walk daily for health, walking every day with the mental burden of getting tired when walking on the same road every day Can be painful. In addition, when riding a bicycle in an urban area, it is necessary to run on the roadway. However, it is often difficult to drive safely due to parking of cars and heavy traffic, so walking on the sidewalk is often performed.

  As an improvement measure, the steering wheel and the auxiliary handle provided on the main body other than the steering wheel are connected by a connecting body with elastic force, and safe and reliable maneuvering performance in a straight posture without burdening the body by operating the auxiliary handle. Therefore, it is possible to realize an auxiliary control device for manually pushing a bicycle or the like that can ensure the above.

Problem 1 (corresponding to claim 1)
When cycling on a steep hill during cycling or when driving in the city with a bicycle, it is dangerous to walk on the sidewalk while pushing the bicycle with both hands. At this time, it is easy to get tired and hurt muscles because the body is twisted and walked. In this way, to realize a bicycle stable operation method that allows the bicycle to be operated straight when walking by hand.

Problem 2 (corresponding to claim 1)
In addition, when walking while pushing the bicycle, it is also a common method to walk while grasping the center part of the handle with one hand, but the weight on the main body side is heavier than the handle part at this time, so if the handle rotates slightly even when looking away, etc. Can't walk stably and straight. If you have a device that automatically corrects the subtle changes in direction when you look away, it will be easier to walk. The task is to achieve this.

Problem 3 (corresponding to claims 1 and 2)
Also, if you walk while pressing the body of the bicycle saddle or the like, you can push it just by reaching out, so there is no burden on your body. However, when the front wheel hits something or the handle bends, such as when the handle touches a passerby or the like, the direction changes greatly or falls. To reduce such problems and realize a safe and secure way to operate in the correct posture.

Problem 4 (corresponding to claims 3 and 4)
Driving a bicycle by hand and riding it again are common. Therefore, it is desired to switch between stable manual driving and riding in a short time. Achieving this in a simple and short time for a stable walking with a hand and a stable walk.

Problem 5 (corresponding to claim 5)
To apply the present invention to an existing bicycle, etc., to realize a method that can be carried out without any modification to the existing car body.

Problem 6 (corresponding to claim 6)
When the rudder is turned with the auxiliary handle, if the connecting body with the handle is only an elastic body, the elongation increases momentarily, so that the handle becomes unsatisfactory. On the contrary, when the connecting body is not an elastic body but a solid substance, the cutting of the handle is very good because there is no play. However, it is too sensitive and difficult to operate. Optimize these conflicting performances.

Problem 7 (corresponding to claim 7)
The length of the coupling body connecting the handle and the auxiliary handle changes when the type of bicycle, the height of the handle, and the height of the saddle are changed. If this cannot be dealt with, it may not be possible to optimize the cutting of the handle, and it may not be possible to attach it due to the length of the coupling body, or the height may not be adjusted. To solve this problem.

  The problem solving means for claim 1 (issues 1 and 2) will be described. When a two-wheeled vehicle or the like is walked by hand, the handle and both ends of the auxiliary handle provided on the main body other than the handle are connected by an elastic body to which the same force is applied as shown in FIG. In this case, when going straight as shown in FIG. 2 (a), it is possible to walk in a straight posture while pushing the auxiliary handle with the right hand, and the tension (or compression force) by the elastic body is applied to the handle. It is similar to holding the handle with both arms, and you can go straight ahead stably.

  Even if the front wheel hits an obstacle when the auxiliary handle is straightened as shown in FIG. 2 (c) or the handle hits something, the handle is bent to the left with respect to the direction of travel. Therefore, the steering wheel can be automatically restored straight, and stable straight running is possible.

  In addition, when the auxiliary handle is turned to the left (right) as shown in FIG. 2 (b), the handle can also be turned to the left (right) via the connecting body, and the vehicle body is bent and walked to the left (right). Can do.

  A solution to claim 2 (problem 3) will be described. As shown in Fig. 3, even if there is no auxiliary handle, if the handle or the part that rotates simultaneously with the handle and the main body other than the handle are connected with an elastic body, holding the saddle part etc. with one hand, It is similar to walking while holding the handle with both hands, and the motorcycle can be operated in a straight line with stability.

  If you want to change the direction of the car body at this time, you can change the direction by tilting the car body toward the direction you want to change. The direction can be changed by correcting the handle straight.

  In this case, it is desirable to provide a mechanism for adjusting the strength of the tension of the coupling body according to the weight, shape, etc. of the vehicle body.

  A solution to claim 3 (problem 4) will be described. When the device of the present invention is applied to a two-wheeled vehicle and a three-wheeled vehicle, various restrictions occur when the device is mounted on the main body depending on the vehicle type, its size, and the like. For example, when attaching to an existing bicycle, it is not easy to attach the auxiliary handle. As a means to solve this problem, utilizing the standard shape of the shaft to which the saddle is attached, the saddle is equipped with an auxiliary handle attachment bearing and integrated with the shaft, or only the saddle is used. If the method provided to the person is adopted, the device of the present invention can be put into use by simply replacing the saddle or the integrated saddle and shaft with the existing bicycle.

  An example of this is shown in Fig. 4. A bearing is provided below the upper surface of the saddle so that the auxiliary handle can be easily inserted into the bearing. At the same time, when the auxiliary handle is removed, the bicycle can be ridden as it is, so even when riding or walking, the operation is easy and can be performed in a short time.

  A solution to claim 4 will be described. When adopting the present invention for a new motorcycle or tricycle, a method is conceivable in which a bearing portion of an auxiliary handle is provided on a main body other than the handle so that the auxiliary handle can be attached and detached.

  As shown in FIG. 5, the auxiliary handle of the present invention is attached to and removed from the bearing portion when the saddle is positioned at the front portion of the saddle so that it does not interfere with the ride and is provided below the upper surface of the saddle for safety. This makes walking and riding easy.

A means for solving the problem (claim 5) will be described. When adapting the present invention to an existing two-wheeled vehicle, it is desirable to be able to adapt without changing the main body of the two-wheeled vehicle or the like. The means for solving this will be described with reference to FIG. 8. The bearing and shaft of the auxiliary handle are unitized by allowing the auxiliary handle to rotate on a flat plate, and a unit connected to the handle is attached to both sides of the auxiliary handle. Is fixed to the upper part of the saddle with a belt or the like. In this way, the device of the present invention can be easily used without remodeling the existing motorcycle.

  Further, in the case of FIG. 9, since it is attached to the rear part of the saddle, there is no need for operation when getting on and off, and the auxiliary handle unit is attached to the upper part of the front wheel frame that rotates simultaneously with the handle and the main body frame of the saddle shaft insertion part as shown in FIG. If the cable is connected with an elastic body such as a rubber cable or the like, no operation at the time of getting on / off is required, and the connecting body does not get in the way when getting on.

  Means for solving the problem (claim 6) will be described. In claim 1, when the handle or a portion that rotates simultaneously with the handle and the auxiliary handle are connected by a solid object such as a pipe, when the auxiliary handle is cut, the handle is cut at the same time according to the amount of movement. It is difficult to operate stably because the steering wheel operation is too sensitive.

  As a means for solving this problem, play (α) is provided between the solids as shown in FIG. In this way, even if the auxiliary handle is cut, the handle is difficult to cut by the play size, so that stable and sharp handle operation can be performed on the same principle as the play of the handle of an automobile.

  Means for solving the problem (problem 7) will be described. When the height of the saddle or the height of the handle is changed, the lengths of the handle and the auxiliary handle change. When the coupling mechanism is all an elastic body, the length automatically changes, but in order to improve operability, the coupling rod is changed to a solid object such as a solid object such as a pipe or a combination of a solid object and an elastic body. If play is provided, the length must be adjusted. This solution will be described with reference to FIG.

  In FIG. 7, a length adjustment mechanism using a screw such as a buckle is incorporated at the end of one of the connecting rods (in the figure, an example on the auxiliary handle side) to adjust the length. realizable. Even if it is not a buckle, it can be realized by combining with other screw types and various length adjustment mechanisms on the market. ←, delete the dollar ←

  When walking on motorcycles and tricycles, you can push the center of the steering wheel with your hand and steer it with both hands, but walking is unstable or walking with a tough posture by twisting your body. However, in the present invention, the auxiliary handle can be steered with one hand in a straight posture, and stable and safe walking is possible.

  Also, when walking for health, walking from home every day, but because it is the usual course, I feel bored and continue to feel resistance, but when using the device of the present invention, I walked far away with a motorcycle. As a result, you will be less tired and can continue walking. In this case, since cycling is also an exercise, not only walking but also a merit of being able to perform complex exercises is born.

  In addition, when a handle hits an obstacle or another pedestrian during walking driving, the steering wheel can be automatically restored by the effect of an elastic body or a solid connected body, so that safe and reliable walking driving is possible.

  In claim 2, although the maneuverability is slightly lowered, the effect of the present invention can be obtained because it is free to get on and off without any operation and the price is easy.

  In claim 3, since the auxiliary handle of the present invention is installed in the saddle, it can be used in existing motorcycles and at the same time can be easily attached and detached, so that it is stable and easy to get on and off, and enables walking and riding safely. Can do.

  In claim 4, when the present invention is applied to a new motorcycle or the like, the bearing portion of the auxiliary handle can be provided at the time of production on a frame other than the handle. Therefore, the effect of the present invention can be obtained only by adding the control unit of the present invention. Can be created, creating the appeal of new motorcycles, making it possible to differentiate from other companies' motorcycles, and expecting advantageous sales expansion.

  According to the fifth aspect, since the auxiliary handle unit is mounted on the saddle with one touch, the effect of the present invention can be obtained with the existing saddle as it is, and it can be applied to various existing vehicles.

  According to the sixth aspect of the present invention, since play is provided in the solid body such as a pipe, a more stable steering operation by play and play is possible.

  In claim 7, since the length of the handle and the auxiliary handle can be adjusted, the unit of the present invention can be applied to a motorcycle of various sizes, and the length adjustment when the handle or saddle height is changed even in the same vehicle. Because it can be easily done, optimal performance is obtained, and the connecting body is divided into a plurality of parts, so when riding the unit of the present invention can be folded down and hooked on the front handle, The effect that it does not interfere with driving is also obtained.

In addition, when riding a bicycle in an urban area, you must run on the roadway, but you can not drive safely due to parking of cars or heavy traffic, so you often walk on the sidewalk by hand, but at this time it is also safe with one hand The two-wheeled vehicle can be used in a safe urban area at the same time, and at the same time, it is less likely to cause trouble for other pedestrians even if they walk on the sidewalk by bicycle.

  The effect of adopting the best mode is that no operation is required when getting on and off the vehicle, and if the auxiliary handle is unnecessary, it can be removed, and when connecting the pedal when riding Since this is a wire cable, it is possible to run exactly the same as when this device is not used.

  Among the best modes, one mode for adapting to an existing motorcycle will be described with reference to FIG. 9. The bearing 901 of the auxiliary handle 911 in FIG. 9 is fixed to a metal fitting 902 for attaching to the rear portion of the saddle 908 by welding or the like. The saddle mounting spring 906 is clamped by a metal fitting 904, and the bearing portion is fixed to the saddle of the main body by mounting bolts 905.

  A bracket 912 for fixing the handle driving connection body 907 to the lower end of the auxiliary handle shaft 903 is fixed to the shaft 903 by welding or the like, and one end of the connection body 907 is fixed in a rotatable state, and the other end is a handle. When fixed to 910, the direction of the handle 910 can be changed by rotating the auxiliary handle 911.

  In order to fix the position of the shaft of the auxiliary handle, a stopper 913 is provided on the shaft 903, and the assembly of the shaft 903 and the auxiliary handle 911 is facilitated by using a method of assembling with a screw after inserting the shaft into the bearing 901. In addition, disassembly is possible.

  In the best mode, the case of a new car will be described with reference to FIG. 10. FIG. 10 (a) shows the whole, and an enlarged view of this is shown in FIG. 10 (b). In (b), a bearing fitting 111 is fixed to a bearing support frame 110 fixed to the main body by welding or the like by press fitting or the like, and a flat shape 113 having a hole capable of rotating the rotation pin 112 at the upper end of the fitting 111 is formed. It is provided and inserted into the upper frame 114 of the bearing via the pin 112 113 so that the upper frame can rotate at the pin 112.

  If the fixing bracket 116 is provided so that rotation does not occur at this hinge portion during walking operation, and if it is lowered to the stopper 117 as shown in FIG. 10 (b) during walking, rotation is impossible, as shown in FIG. 10 (a). When the user gets on the vehicle, the vehicle is lifted up and the auxiliary handle is tilted forward as shown in FIG. 10 (c), so that the user can get on without getting in the way.

  Therefore, the switching time between boarding and walking is short, so that walking can be enjoyed with simple work, and when it is unnecessary, it can be boarded and moved quickly.

  Among the best modes, the case of adopting the optimum plural system of the present invention will be described with reference to FIG. 11. In FIG. 11A, a handle driving bar 217 is bolted to a front wheel frame portion 220 that rotates simultaneously with the handle 211. 235 or welded, and one end of the coupling body is attached to both ends thereof. When coupled to both ends of the bar 221 attached to the rotary shaft 216 of the auxiliary handle 213 via an elastic body such as rubber and a wire cable 219, the auxiliary body The rotation of the handle 213 rotates the handle by the coupling bodies 219 and 214 so that the steering can be performed during walking, and the user can get on and travel as it is during traveling.

  11A is described in detail with reference to FIG. 11B. The bearing portion of the auxiliary handle is connected to the bearing member 123 and the support member 234 by welding or the like, and is attached to the support member 234. A metal fitting 228 is welded, and the main body frame 218 is fixed by being sandwiched between the attachment metal fitting and the bolt 229. In the case of manufacturing a new vehicle, the support member 234 may be welded directly to the frame 218.

  In addition, a slit 124 is provided at the upper end of the rotation shaft 216 of the auxiliary handle, and when the pipe-shaped shaft 215 having the rotation transmission plate 226 of the auxiliary handle 213 is inserted and inserted to the back, this is the case. The slit 124 and the rotation transmission plate 226 mesh with each other to enable steering, and when the handle is obstructed, it can be removed. Of course, the pipe-shaped shaft 233 of the auxiliary handle and the rotation transmission plate 226 are coupled by welding or the like.

  In FIG. 11B, reference numeral 230 denotes an outer cable of the wire cable 219. Both ends of the outer cable 230 are fixed to the main body frame by fixing brackets 232, and the inner wire 231 as a connecting body is connected to the auxiliary handle side. The bar 221 is coupled to both ends, and the other end is coupled to an elastic body such as rubber. The elastic body such as rubber is coupled to both ends of the handle driving unit 217 in FIG. 11C, and rotates the auxiliary handle 213. As a result, the handle 211 can rotate simultaneously. In the case of manufacturing a new vehicle, the handle driving unit bar 217 may be directly welded to the front wheel frame unit 220.

  In FIG. 11 (c), which is a detailed view of FIG. 11B, since the elastic body 214 such as rubber of the connecting body is connected to the handle driving bar 217, when the present invention is applied to the folding bicycle, Since the connecting part of the part to be folded is rubber, it can be prevented from getting in the way. Furthermore, if a hooking metal fitting is used at this coupling end part, it can be detached, so that the folding is further facilitated.

  The effect of this form is that it can be switched instantly without any operation when getting on and off, and it does not get in the way when getting on, and there is no need to adjust the length of the connected body even if the height of the handle or the saddle is changed As described above, in the folding bicycle, there is almost no hindrance to the folding operation in a compact manner.

  An embodiment relating to claim 1 will be described. In FIG. 1, one end of two connecting bodies 105 made of an elastic body or a solid bar is attached to a general bicycle handle 101 including a handle 101, a saddle 103, a frame 107, and wheels 104 from the center of the handle. The bearings of the auxiliary handle 401 of FIG. 4 are fixed to the distances A1 and A2 through the fixing mechanism 106 at positions of substantially the same length and provided on the main body other than the handle (in FIG. 4, the saddle portion is taken as an example). The part 403 and the shaft 402 of the auxiliary handle inserted therein are made rotatable.

  When maneuvering a two-wheeled vehicle by hand, the handle 102 is held with one hand and walks in a straight posture as shown in FIG. 1 (a), but when it is desired to turn left and right, the auxiliary handle is rotated left and right. Referring to FIG. 2B, when turning to the left, if the auxiliary handle is bent to the left, the left connecting body 201 pushes the handle forward, the right connecting body 202 pushes the handle in the traveling direction, Rotate left. When the bending is completed, when the auxiliary handle is returned to the original position, the handle becomes perpendicular to the traveling direction and can return straight.

  As shown in Fig. 2 (c), if an elastic body is used for the connecting body, it is possible to walk stably and safely. When the auxiliary handle is straight and straight, the front wheel rides on some obstacle. When the handle touches an object such as another pedestrian or a road sign, the handle turns in the direction in which the force is applied (to the left in the figure). At this time, due to the force of the elastic body and the repulsive force of the solid Since the restoring force is automatically applied to the steering wheel, it is possible to perform the walking by pushing the two-wheeled vehicle or the like that is very stable and safer than the free walking that has been performed until now without the device of the present invention.

In addition, since the same effect is acquired also with the elastic body which has compressive force like a compression spring, it is also possible to use a compression spring instead of tension | tensile_strength. In addition, the reaction is also sensitive when connected by a solid such as a rod instead of an elastic body, but it can be considered to be one of the present inventions because it can be pushed more stably than a free push.

  An embodiment relating to claim 2 will be described. Even if the auxiliary handle is not provided, an example of a more stable and safe device than when the hand-held walking of a two-wheeled vehicle is carried out will be described with reference to FIG. In a state where the body 301 is under tension, the body 301 is fixed using a fixing metal fitting 303, and the other end is fixed to a main body frame other than the handle. In the drawing, the foot is fixed to the lower frame 302 of the saddle so that the foot does not get in the way when getting on and off.

In this case, the stability and safety of the maneuvering by the obstacle described in the first embodiment is equivalent, and when changing the direction, the direction can be changed by the method described in the solution means of claim 2. Since this device can be used to get on and off the motorcycle without any operation, it requires a little technology to change the direction, but it can be said that it is convenient and does not cost much.

  An embodiment relating to claim 3 will be described. The present invention with an auxiliary handle in the saddle makes it possible to push and walk in a straight posture, and is easy to operate when getting on and off when the present invention is applied to an existing motorcycle or the like. One way is to replace the saddle. The present invention relates to this saddle exchange system.

  By the way, the shaft to which the saddle of the motorcycle is attached is standardized, and it is a very easy method to replace it with the assembly of the saddle and its shaft. However, a method of exchanging the saddle alone is also possible, but since it is a structure that takes a little time for an amateur, the case of exchanging the shaft and the saddle will be described here.

  The embodiment of the present invention will be described with reference to FIG. 4. A saddle body 409, a cushion material 408, and a saddle surface sheet 407 are attached to a saddle shaft 410 via a saddle attachment member 412.

  The following functions are added to this saddle assembly. A through hole 413 is formed in the center of the saddle, and an assembly of a bearing pipe 403 and a mounting screw member 406 integrated with an adhesive or the like is fixed to the saddle main body 409 with a mounting nut member 404 via a reinforcing plate 405. To do. The shaft 402 of the auxiliary handle 405 having a fitting degree of a level that can be smoothly rotated is inserted into the bearing 403 so as to be detachable. The auxiliary handle 401 and its shaft 402 are fixed with an adhesive or the like, and the connecting member 411 is attached to the auxiliary handle 401 at the same length with respect to the center.

  With this configuration, when the auxiliary handle 401 is rotated, the handle can be freely operated via the interlocking member 411, and when riding a two-wheeled vehicle, it is possible to get on immediately by simply removing the auxiliary handle. become. If the removed auxiliary handle assembly can be hooked on the handle or the like, comfortable driving can be performed without hindering driving.

  An embodiment relating to claim 4 will be described. Up to now, the case where the present invention is applied to an existing motorcycle or the like has been described. However, in this embodiment, the embodiment of claim 4 when applied to a new motorcycle or the like will be described with reference to FIG. The bearing portion 503 of the handle 501 is attached to the frame by welding or the like. In this case, it is desirable that the mounting position does not interfere with getting on and off, and the upper end of the bearing is below the upper surface of the saddle 504 for safety. Further, this bearing position can be attached to a position such as 507 in FIG.

The bearing portion 503 is inserted into the shaft 502 of the auxiliary handle, the two connecting bodies 505 are attached to both ends of the auxiliary handle, and are connected to the handle via the mounting bracket 506, and according to the principle described in claim 1, Realize maneuvering while walking with peace of mind.

  An embodiment relating to claim 5 will be described. An embodiment in which the present invention is applied to an existing motorcycle or the like without any modification will be described with reference to FIG. 8. A bearing unit 1 has a bearing cover 803 attached to a mounting plate 802 with screws or the like, and a shaft that is a cylindrical flat plate therein. 805 and a shaft 804 integral therewith are mounted, and the shaft 804 is fixed to the auxiliary handle 801. Two connecting bodies 814 are attached to both ends of the auxiliary handle 801, and the ends thereof are coupled to the handle 813. The bearing unit 1 can be fixed to the center of the upper surface of the saddle 810 attached to the saddle shaft 809 by a front belt 812 and a rear attachment belt 811. The drawing shows a state in which the fastening fitting 806 is used as an example of the fixing method. In this way, when the auxiliary handle 801 of the bearing unit 1 attached to the saddle is operated, a stable and safe walking is possible during a manual walking.

This embodiment shows only one example. The present invention includes that the bearing mechanism provided on the mounting plate 802 can be realized by various other methods, and at the same time, the bearing unit 1 can be mounted on the saddle. The method is also an example, and other general attachment methods are also included in the present invention.

  An embodiment relating to claim 6 will be described. In the present invention, it has been described that it is also effective to make the connecting body that connects the auxiliary handle and the handle solid. However, at this time, a slight rotation of the auxiliary handle is transmitted to the handle and is too sensitive to cause mental pain in operation. FIG. 6A illustrates an embodiment of claim 6 which is a device for solving this problem.

  A connecting body is coupled to the auxiliary handle 601 by a screw 612 via a mounting bracket 611. The coupling body includes a handle-side pipe 603 and an auxiliary handle-side pipe 604 that are divided into two parts (or more than that), and an elastic body (rubber or spring) 602 that generates tension after being attached to the inside. When a play α shorter than the length of the handle and the auxiliary handle is provided on the divided solid connection body, when the auxiliary handle 601 is rotated (left), the play α of the outer connection body (right in the traveling direction) is obtained. Minute connections are not attached. As a result, the sensitivity of maneuvering is eased like the play of the steering wheel of an automobile, and at the same time, the direction change can be performed smoothly after the play is lost.

  Note that the bolt nut 610 is an integral body of the connecting body 604, the elastic body 602 on the auxiliary handle side, and the mounting bracket 611. In this portion, the rotation is free but the length does not change. Further, the bolt nut 608 connects the mounting bracket 606 to the handle 606, the elastic body 602, and the connecting body 603 on the handle side so that the length can be freely rotated and the length of the bolt nut 609 can be prevented from slipping with the handle 605. The fixing bracket 606 to the handle is tightened through the rubber plate 607.

  When dividing the connection body, there is a risk that the connection body may be bent at this portion during direction change and the handle may not be cut reliably. In this case, as shown in FIG. If one end of the deformable cylindrical guide 613 is fixed to the solid coupling body 604 with a band 614 or the like, this can be prevented.

  An embodiment relating to claim 7 will be described. An embodiment relating to claim 7 for solving the change in the distance between the auxiliary handle and the handle will be described with reference to FIG. 7. The mounting bracket 720 is fixed to the auxiliary handle 701 with a screw 721. And a hole at the end of the buckle screw 718 for adjusting the length are coupled so that the bolt nut 719 is rotatable, and the reverse screw is cut so that the distance B changes when the buckle body 717 is rotated. The connecting screw 716 is integrated with the connecting body 713 on the auxiliary handle side by bonding or the like, and is also coupled to the elastic body by a bolt nut 715, and the connecting body 712 is elastically connected to the inside through the play α. While having a body 714, it is connected to a handle fitting 711 and a bolt nut 705.

  Further, it is coupled to the hole 709 of the coupling bracket 711 by a bolt nut 704 via a bolt portion holding portion 703 ′ (refer to an enlarged view) of the bolt nut 704 of the mounting bracket 703 to the handle. When the bolts and nuts 707 are fixed to the handle via the stop sheet 706, the auxiliary handle and the handle can be connected in a state where the hole can be rotated in the hole 709. As a result, the length of the auxiliary handle and the handle can be adjusted. Can be realized by rotating the buckle 717.

  Note that the present invention can be realized not only by the above-described embodiments but also by other length adjusting methods such as bolts and nuts as well as buckles.
