Description

  The present invention relates to a folding bicycle that can be folded and made to stand by an easy operation, and a bicycle cover that is used by covering the bicycle when the bicycle is folded and transported.

  First, the prior art regarding a folding bicycle will be described. The following Patent Documents 1 and 2 are documents related to the prior art of folding bicycles.

  Conventionally, bicycles have been used as an easy means of transportation, and in recent years, various folding bicycles have been provided for use such as carrying while using public transportation such as trains or mounting them in automobiles. Yes. These folding bicycles exist in various forms according to the purpose of use, such as those suitable for compactness and transportation in the folded state.

  As one of the purposes of using such a folding bicycle, in recent years, there has been an increasing need as a transportation means in combination with public transportation such as carrying a bicycle and using a train. Folding bicycles used in such moving means require various functions assuming that the user carries the vehicle body, such as miniaturization of the vehicle body, compactness in the folded state, and ease of transportation. Is done. In addition, when the folding bicycle is run after using public transportation other than when the folding bicycle is transported, the environment is not limited and the vehicle body is stable with respect to the mutual deformation operation of the running mode and the carrying mode (folded state). It is desirable that it can be performed in the above state.

  The folding bicycle disclosed in Patent Document 1 is provided as an example that takes into consideration the deformation operation into the carrying form and the ease of transportation. In the folding bicycle of Patent Document 1, the center of the main frame and the handle pipe are simultaneously opened and closed, and the folding bicycle is deformed from the running configuration to the carrying configuration. Moreover, the carrier is provided with a carry so that the folding bicycle can be transported stably.

  The folding bicycle of Patent Document 2 has a structure in which the entire body is erected by grounding the loading platform provided at the rear of the folding bicycle when it is transformed from a running configuration to a carrying configuration, and then the center of the main frame is folded and folded. ing.

  Next, the prior art related to the bicycle cover will be described. The following Patent Documents 3 to 6 are documents related to the prior art of bicycle covers.

  When a bicycle occupant transports a bicycle using public transportation (railway, ship, airplane, etc.), it is called wheeling. In such a cycle, it is often required to store the bicycle in a bag.

  It is a common practice to carry a folded bicycle with a cover even when it is not traveling.

  Japanese Patent Application Laid-Open No. H10-260260 discloses a traveling bag that accommodates a folding bicycle, in which a bag body is provided with a lower opening that can be opened and closed and has an opening and closing means, and an upper opening that can be opened and closed and has an opening and closing means.

  Patent Document 4 discloses a two-wheeled vehicle cover in which steel wires are disposed on the upper and lower openings of the cover.

  Patent Document 5 discloses a saddle cover that can be detachably attached to a component part of a saddle.

  Patent Document 6 discloses a saddle cover that is locked to a vertical frame that supports the saddle.

JP 2012-176638 A JP 2010-184523 A JP 2010-17199 A JP 2008-44486 A Registered Utility Model Publication No. 3034644 Registered Utility Model Publication No. 3013400

  However, when the folding bicycle of Patent Document 1 is folded, the substantially center of the main frame and the connection portion with the head pipe are bent at the same time. Therefore, not only the posture of the main frame changes during the folding work, but also the saddle attached to the rear wheel side of the main frame tilts rearward and the posture of the entire vehicle body changes greatly. When the vehicle body is in an unstable posture as described above, it is necessary for the user to deform the carrying form while supporting and stabilizing the vehicle body. In some cases, the vehicle body may be in an unstable posture and fall over. Therefore, it is necessary to avoid a place where many people come and go in consideration of the place where the folding work of the folding bicycle is performed.

  Further, in the folding bicycle of Patent Document 2, it is necessary to lift the front wheel side upward and to stand substantially vertically over the entire length of the vehicle body in order to be carried. Although the deformation operation of the folding bicycle can be performed in a small space, such an unstable posture of the vehicle body further increases the risk of the vehicle body falling.

  As described above, the conventional technology does not have a structure that stabilizes the vehicle body in the folding operation. Although various folding bicycles with reduced weight are provided, there is a limit to the weight reduction of the bicycle structure, and it is preferable that the folding bicycle does not require an operation of lifting the folding bicycle for deformation to the carrying form .

  Therefore, the folding bicycle of the present invention aims to realize a deformation operation in a stable state without greatly changing the posture of the vehicle body with respect to the mutual deformation of the traveling form and the carrying form.

  A general-purpose wheel bag is a bag body whose overall shape is made of cloth or the like, and has an opening that is large enough to accommodate a folded bicycle, and an opening and closing means such as a fastener provided at the periphery of the opening. And a belt for carrying on the shoulder.

  Such a conventional wheel bag must be laid on the ground when the folding bicycle is accommodated, and there is a drawback in that the wheel bag becomes dirty. On the other hand, a bicycle bag that can be worn over the bicycle is less likely to get dirty when the bicycle is stored, but the bicycle body and the bicycle bag are separate, so there is a risk of forgetting to carry the bicycle bag. There is. If you bring it to a public institution, forgetting it is a fatal defect and there is a concern that you will be refused boarding the public institution.

  Further, when storing a folded bicycle in a wheel bag, the wheel bag must be laid on the ground and the bicycle must be carried to the position where the wheel bag is laid, which takes time and effort.

Furthermore, when carrying a bicycle carrying a folded bicycle on the shoulder using a belt or carrying it by hand, the weight of the folded bicycle must be applied to the carrying bag with the belt and belt attached. become.

  In this way, the weight of the bicycle is supported by the wheel bag, and it is necessary to use a material having a high strength as the material of the wheel bag. In other words, it is required to use a thick and sturdy material for the wheel bag, and the wheel bag is inevitably heavy and bulky.

  Also, carrying a heavy and bulky wheel bag as described above when riding a bicycle may impair driving comfort and safety.

  In order to solve the above-mentioned problems, the present invention can be easily and quickly put on a folding bicycle without the trouble of laying on the ground or operating the bicycle on a cover. An object of the present invention is to provide a bicycle cover that can be manufactured using a thin and lightweight material and also has a saddle cover.

  The folding bicycle of the present invention provided to solve the above-mentioned problems is a folding bicycle that can be transformed into a traveling form that can be ridden and traveled and a carrying form in which the frame is folded. A loading platform portion that constitutes a loading platform, wherein the frame is a front wheel frame that is connected to a front wheel, a rear wheel frame that is connected to a rear wheel, and from the vehicle body front side to the vehicle body rear side in the traveling mode. A main frame that extends and is connected to the front wheel frame and the rear wheel frame; and the main frame can rotate the rear wheel frame about an axis that extends in a direction along the axle of the rear wheel. A rotating part, and the loading part is provided at a position above the rear wheel in the traveling form, and is transformed from the traveling form to the carrying form. In the process of turning, the rear wheel frame is rotated with respect to the main frame in the rotating portion, so that the end of the cargo bed portion is grounded and stands up. It is.

  According to the folding bicycle of the present invention, in the operation of deforming the folding bicycle from the running configuration to the stand configuration, the vehicle body is unstable, such as the user lifting the vehicle body or standing the entire vehicle body with the front wheel facing upward. No action is required.

  Furthermore, in the folding bicycle of the present invention, the posture of the main frame and the saddle does not change greatly and the posture of the entire vehicle body does not change greatly in the deformation operation from the running form to the stand form. Therefore, it is possible to stably perform the deformation operation while avoiding problems such as unexpected balance loss during the deformation operation of the vehicle body.

  As described above, the folding bicycle of the present invention can be transformed into a stand form by an easy operation. As a result, the deformation operation of the vehicle body can be performed without relatively selecting a place. Moreover, when performing further deformation | transformation operation | movement so that a folding bicycle may become further compact after that, it can work in the state (stand form) where the vehicle body became independent. Thereby, also in the further further deformation | transformation operation | movement after that, a deformation | transformation operation | work can be performed after stabilizing a vehicle body.

  The loading platform portion of the folding bicycle of the present invention has a pair of downspouts and a recumbent bridge connecting the pair of downspouts so that the downspout extends along the main frame in the travel mode. And at least a reed side reed connected to the end of the downside of the vehicle body as the reed, and in the stand form, between the pair of reeds It is desirable that the rear end side reed can be stepped on by inserting the user's toe.

  According to the above-described configuration, when the folding bicycle is in a stand form or a carrying form, the rear end side reed is located under the user's foot. The position of the vehicle body can be maintained so that the vehicle body does not move unnecessarily by the user's stepping on the rear end side reed. Thereby, when a user carries the folding bicycle of the present invention and gets on a train or a bus, the user can withstand the shaking and vibration of the train and can hold the position of the vehicle body.

  In the folding bicycle of the present invention, wheels may be provided on the loading platform, and in the form of the stand, the wheels may be grounded.

  According to the above configuration, when the folding bicycle of the present invention is transported, it can be transported smoothly while the wheels are grounded.

  In the folding bicycle of the present invention, wheels are provided in the loading platform, and in the stand form, the wheels are grounded, and the rear end side reeds are positioned close to the rotating shaft of the wheels. It may be arranged.

  According to the above-described configuration, the operation of stepping on the user's rear end side recumbent plays the role of a wheel brake. For this reason, it is possible to prevent the vehicle body from moving due to the wheel rotating unnecessarily.

  The folding bicycle of the present invention may be configured in such a manner that the rear wheel frame is rotated with respect to the main frame by stepping on the rear end side reeds downward to form the stand.

  According to the above-described configuration, in the deformation operation from the traveling form to the stand form, the user can perform the operation by stepping down the recumbent with his / her foot, so that the traveling form can be further easily transformed into the stand form.

  The folding bicycle of the present invention has a stand configuration in which the stand configuration can be maintained by locking a locking portion provided on the main frame side and a locked portion provided on the rear wheel frame side. It is desirable to have a retention mechanism.

  According to the above-described configuration, the stand form can be stably held. Therefore, when the bicycle is parked in the stand form, or when the bicycle is further folded from the stand form and transformed into the carrying form, the work can be performed more stably.

  The folding bicycle of the present invention preferably includes a saddle pipe that connects a saddle to the main frame, and a grip portion that a user can hold is provided on the saddle pipe.

  According to the above-described configuration, in the folding bicycle carrying configuration, the user can carry the folding bicycle while grasping and pulling the handle portion.

  Furthermore, the folding bicycle of the present invention can be towed in a predetermined towing direction in the carrying configuration, and it is desirable that the handle portion projects to the saddle in the towing direction or the side opposite to the towing direction. .

  According to this configuration, the handle portion is positioned along the pulling direction, and the vehicle body can be pulled and transported smoothly and efficiently.

  Further, it is desirable that the above-described handle portion can be rotated about the saddle pipe as a rotation axis.

  According to the above-described configuration, in the traveling mode, the user can hook the baggage or the like and use it for transporting the baggage, or in the carrying mode, the user can be positioned in a direction that is easy to tow when carrying the folded bicycle. As a result, the handle portion can be positioned according to the form of the folding bicycle and the convenience of the user.

  The main frame preferably has a folding mechanism for opening and closing the main frame in the longitudinal direction.

  According to the above-described configuration, the front wheel frame can be folded in the rear wheel direction by opening and closing the folding mechanism, and the longitudinal direction can be further reduced as compared with the stand form. As a result, the vehicle body can be folded more compactly and can be suitably used for carrying.

  The wheel described above includes n sub-wheels and a connecting portion that connects the n sub-wheels, and the n sub-wheels are arranged so as to form a substantially regular n-gon. It is also possible to adopt a structure in which the connecting portion can rotate around the center of the regular n-gon.

  According to such a configuration, when the vehicle body is transported at a level difference, the sub-wheel is grounded to both the lower stage and the upper stage, and the entire vehicle body is pulled to the upper stage side by using the axle of the auxiliary wheel that contacts the upper stage side as a rotation fulcrum. Is done. Thereby, the force which lifts the vehicle body upward can be reduced and the vehicle body can be transported relatively easily. Therefore, it can be suitably used when the folding bicycle is pulled and transported on the staircase of a station or the like.

Through this, a part or all of the cover main body can be accommodated in the first accommodating portion.

  According to the cover of the present invention, the cover body can be attached to the rod-shaped member of the covering object in a state where the cover main body is accommodated in the first accommodating portion. That is, when the covering object is not covered with the cover main body, the cover main body can be accommodated in the first accommodating portion and the entire cover can be carried in a compact size. Moreover, in the cover of this invention, a cover main body can be withdrawn / inserted from the opening of a 1st accommodating part, attaching the 1st accommodating part to the rod-shaped part of a covering target object. Therefore, the cover main body can be taken out from the first housing portion in a state in which the first housing portion is mounted on the rod-shaped portion of the covering object, and the covering object can be covered. As described above, the cover of the present invention can be attached to the rod-shaped portion of the covering object through the case where the covering object is covered and the case where the covering object is not covered. Thereby, the cover of the present invention can suppress forgetting to carry the cover, and can quickly cover the covering object when it is desired to cover the covering object.

  In the cover of the present invention, the covering object is a bicycle having a rod-shaped portion, and the cover main body includes an introduction portion capable of forming an opening through which a part or all of the bicycle can be taken in and out, and the first accommodation portion. A connection portion connected to the cover body, the cover main body being partly or entirely covered, and being able to be accommodated in the first accommodation portion through any one of the openings provided in the first accommodation portion. It is characterized by being.

  In the cover of the present invention, when the bicycle is to be covered, the cover body can be taken out from the first accommodating portion and the bicycle can be covered from the opening of the introduction portion. Moreover, the cover of this invention can be accommodated in a 1st accommodating part from opening of an accommodating part over a cover main body, when not covering a bicycle. Furthermore, the cover of the present invention can be attached to a rod-like portion (pipe portion or the like) of the bicycle, whether or not the bicycle is covered. As a result, the cover of the present invention can prevent forgetting to carry the cover, and can quickly cover the whole or a part of the bicycle in response to sudden rain.

  The cover of the present invention is characterized in that the rod-shaped portion is a seat post connected to the saddle of the bicycle, and the cover body can be mounted so as to hang down from the seat post side.

Thereby, it can suppress that rain etc. penetrate | invade from the upper part into the inside of a 1st accommodating part.

  Here, a bicycle including a folding bicycle is generally configured to have wheels, a main frame, a front wheel frame, a rear wheel frame, a saddle, a front basket, and the like. When covering all the components of the bicycle (the entire bicycle), it is necessary to cover the saddle and the front basket that protrude away from the main frame. Therefore, when it is intended to cover the entire bicycle with one bag, the bag (main body cover) needs to have a corresponding size.

  However, there are cases where the main parts such as the wheels and the main frame and the parts such as the saddle and the front basket are different in the situation to be covered. For example, when the bicycle to be covered by the cover is a folded bicycle, the bicycle may be covered to carry the folded bicycle and get on public transport (transportation). When using a cover for the purpose of transporting such a folded bicycle, it is sufficient to cover only the main part including the bicycle wheel and the main frame, and it may not be necessary to cover the saddle or the front basket.

  On the other hand, when riding on a bicycle wet with rain, the user may want to cover only the saddle or the front basket. In such a case, it is difficult to use a cover having only a cover body that covers the entire bicycle depending on the situation. Furthermore, the saddle, the front basket, and the like are often configured to protrude from the main portion of the entire bicycle, and covering the entire bicycle including both the saddle and the main portion of the bicycle is wasteful in the cover body. A large storage area is generated, and the overall appearance of the bicycle and the bag body must be large.

  In the cover of the present invention provided to cope with such a problem, the covering object is a part or the whole of a bicycle having a rod-like portion, and the saddle or the front basket that is a part of the bicycle is covered as a covering object part. A sub-cover body that is possible, the sub-cover body being connected to the first housing portion, and capable of housing the sub-cover body through an opening formed in the first housing portion. It is characterized by.

  According to the above configuration, when the bicycle is to be covered, the main part of the bicycle can be covered with the cover body, and the saddle, the front basket and the like can be covered with the sub cover body. That is, if the main part of the entire bicycle is covered with the cover body and the saddle is covered with the sub-cover body, the covered state is compared with the case where the entire bicycle is covered with one bag. The bicycle and the bicycle cover can be made compact. Thereby, a cover main body can be made compact by using a cover main body as a bag body of a comparatively small accommodation area | region. Furthermore, the bicycle which is a covering target can be covered according to the situation where the covering target is to be covered and the part to be covered.

  The cover according to the present invention has a second housing portion that allows the covering object to be a part or all of a bicycle having a rod-like portion and accommodates the sub-cover body, and has an opening in the second housing portion. At least two sub-opening forming portions that can be formed are provided, and the second housing is provided by inserting the rod-like portion through the opening provided in the second housing portion and penetrating the second housing portion. The sub-cover body can be attached to the rod-shaped portion, and the second cover portion is attached to the rod-shaped portion, and the sub-cover body through any one of the openings formed by the sub-opening forming portion. It is good also as being able to accommodate a part or all of in the said 2nd accommodating part.

  According to the above-described configuration, it is possible to cover only the main part of the bicycle by taking out only the cover main body from the first housing portion while the sub cover body is housed in the second housing portion. On the other hand, when it is intended to cover the saddle or the like with the sub-cover body, the sub-cover body can be deployed to cover the saddle or the like while the cover main body is accommodated in the first accommodating portion. That is, the target portion of the bicycle can be covered according to the situation in which the main portion of the bicycle, the saddle, etc. are to be covered while the cover main body and the sub cover body are accommodated. As a result, according to the cover of the present invention, the cover can be used in various modes according to the situation, and the convenience for the user is improved.

  In the cover of the present invention, a part or all of the opening may be capable of reducing the size of the opening region.

  If the opening area of the cover main body or the sub-cover body can be narrowed, the state of covering the covering object can be maintained more reliably. That is, the cover of this invention can suppress that a cover main body and a sub cover body are covered with a wind, and remove | deviate from a covering target object. Moreover, if the opening area | region of a 1st accommodating part or a 2nd accommodating part can be restrict | squeezed, the state which accommodated the cover main body and the sub cover body can be maintained more reliably.

  The cover of the present invention may be configured such that a part or all of the opening can be contracted by a stretchable member having stretchability.

  If the opening of the cover main body or the sub cover body can be expanded and contracted, it is possible to more reliably maintain the state of covering the covering object. That is, the cover of this invention can suppress that a cover main body and a sub cover body are covered with a wind, and remove | deviate from a covering target object. Moreover, if the opening of a 1st accommodating part or a 2nd accommodating part can be expanded-contracted, the state which accommodated the cover main body and the subcover body can be maintained more reliably.

  ADVANTAGE OF THE INVENTION According to this invention, the folding bicycle which can implement | achieve a deformation | transformation operation | movement in the stable state can be provided, without changing the attitude | position of a vehicle body about the mutual deformation | transformation of a running form and a carrying form.

  Hereinafter, embodiments of the folding bicycle of the present invention will be described in detail. The folding bicycle 10 can be transformed into at least three forms by opening, closing, or rotating a part of the configuration. Specifically, the folding bicycle 10 has a “running configuration” in which the user can ride and travel as shown in FIG. 1, and a “stand configuration” in which the folding bicycle 10 shown in FIG. And it can deform | transform into three forms of the "carrying form" which the user shown in FIG. 3 can pull the folding bicycle 10, and can carry it.

  First, an overall configuration of the folding bicycle 10 will be described with reference to a traveling form of the folding bicycle 10. FIG. 1 is a side view showing a traveling form of the folding bicycle 10. As shown in FIG. 1, the folding bicycle 10 includes a main frame 20, a rotation unit 60, a front wheel frame 40, and a stand unit 70. The stand unit 70 includes a rear wheel frame 72, a loading platform unit 100, and carry members 110a and 110b (wheels).

  In the following description, the “longitudinal direction” means the axial direction of the main frame 20 in the traveling form of the folding bicycle 10 unless otherwise specified. Further, “front of the vehicle body” means the front of the folding bicycle 10 in the traveling direction, and “rear body” means the rear of the folding bicycle 10 in the traveling direction.

  The main frame 20 is supported by being connected to the front wheel frame 40 at the front of the vehicle body and to the rear wheel frame 72 at the rear of the vehicle body. In the main frame 20, a first frame 22 positioned in front of the vehicle body and a second frame 24 positioned in the rear of the vehicle body are connected via a first joint portion 30 (first folding mechanism).

  A positioning portion 132, which will be described in detail later, is formed at the end of the second frame 24 on the vehicle body rear side. Further, a seat tube 26 is formed at a position behind the vehicle body of the second frame 24 and close to the positioning portion 132. The seat tube 26 has a cylindrical shape having a through hole. Further, the seat tube 26 is provided from the lower side to the upper side of the second frame 24 so as to intersect the second frame 24 in the axial direction. A seat post 27 is fitted into the through hole of the seat tube 26, and a saddle 28 is further attached to the upper portion of the seat post 27.

  The first joint portion 30 (folding mechanism) is located closer to the front of the vehicle body than the substantially longitudinal center of the main frame 20, and can open and close the first frame 22 and the second frame 24 in the horizontal direction. Specifically, as shown in FIG. 4, the first joint portion 30 includes a first flange portion 36 formed at the end portion of the first frame 22 and a second flange formed at the end portion of the second frame 24. The part 38 is connected via the hinge part 32. The first flange portion 36 and the second flange portion 38 can be opened and closed with the hinge portion 32 as a swing fulcrum. A first fitting portion 36 a is further formed in the first flange portion 36. A first lock member 34 is attached to the first fitting portion 36 a via a lock shaft 35. A second fitting portion 38a is formed in the second flange portion 38, and a concave portion 38b is formed in the second fitting portion 38a. When the first frame 22 and the second frame 24 are closed and locked, the lock shaft 35 is fitted into the recess 38 b and is locked by the first lock member 34. Thus, the main frame 20 can be opened and closed in the horizontal direction by the first joint portion 30, and the front wheel frame 40 can be folded to the rear wheel 74 side.

  The rotating part 60 is provided on the vehicle body rear side of the second frame 24. The rotation part 60 is comprised from a pair of side surface structure body 64a, 64b and the rotation fulcrum 62a, 62b provided with respect to the side surface structure body 64a, 64b. As shown in FIG. 1, the side surface structures 64 a and 64 b have a substantially “<shape” shape formed from the second frame 24 to the seat tube 26. The side surface structures 64a and 64b are disposed on both sides of the side surface of the second frame 24 so as to sandwich the second frame 24 therebetween.

  The rotation fulcrums 62a and 62b are through holes provided for the side surface constituting bodies 64a and 64b. An axis passing through the rotation fulcrums 62a and 62b is configured to extend in a direction along the axle of the rear wheel 74. A connecting shaft 84, which will be described later, is attached to the rotation fulcrums 62a and 62b, and the stand unit 70 is connected.

  The front wheel frame 40 forms a skeleton on the front wheel 42 side of the folding bicycle 10. The front wheel frame 40 includes a front fork 44, a head tube 46, a handle post 48, a handle 49, and a second joint portion 50. The head tube 46 is fixedly connected to the first frame 22. A front fork 44 is connected to the lower end portion of the head tube 46, and a handle post 48 is attached to the other end side of the head tube 46 via a second joint portion 50. A front wheel 42 is pivotally supported at the lower end of the front fork 44.

  The second joint portion 50 is provided so that the head tube 46 and the handle post 48 can be folded. The 2nd joint part 50 is provided with the hinge part and the locking member similarly to the 1st joint part. The basic structure of the second joint unit 50 is the same as that of the first joint unit 30. Therefore, detailed description is omitted here.

  Next, the stand unit 70 will be specifically described. As shown in FIG. 1, the stand unit 70 includes a rear wheel 74, a rear wheel frame 72, a power transmission mechanism 90, a cargo bed unit 100, and a carry 110 (wheel). The stand unit 70 is integrally configured, and is attached to the main frame 20 using the rotation fulcrums 62a and 62b of the rotation unit 60 as rotation fulcrums. The power transmission mechanism 90 transmits the power given to the pedal 96 to the rear wheel 74 via a chain 94 attached from the chain ring 92 to the rear wheel 74. As shown in FIG. 1, the chain ring 92 is attached to the rear wheel frame 72.

  Hereinafter, the stand unit 70 will be described in detail with reference to a perspective view of the stand unit 70 shown in FIG. In FIG. 5, the rear wheels 74 and the power transmission mechanism 90 are not shown.

  The rear wheel frame 72 forms a pair of frames by connecting frames 80a and 80b, chain stays 76a and 76b, and seat stays 78a and 78b. The pair of frames are connected by a support base 88 and a cargo bed part 100. Shaft holes 82a and 82b are formed at the ends of the connecting frames 80a and 80b, respectively, and the connecting shaft 84 passes through these shaft holes 82a and 82b.

  The connecting shaft 84 passes through the rotation fulcrums 62 a and 62 b provided in the rotation unit 60 and is connected to the main frame 20 side. As described above, the axis passing through the rotation fulcrums 62a and 62b is configured to extend in a direction along the axle of the rear wheel 74. For this reason, the connecting shaft 84 and the axis of the rear wheel 74 are arranged substantially in parallel. The rear wheel 74 is attached to and supported by the chain stays 76a and 76b.

  As shown in FIG. 5, the loading platform 100 includes vertical hooks 102 a and 102 b extending from the front to the rear of the vehicle body, and support hooks 104 a and 104 b connected to the seat stays 78 a and 78 b, which are connected by curved parts 103 a and 103 b. A frame serving as a pair of side surfaces is formed. Further, the vertical rods 102a and 102b are connected by a first horizontal rod 105 (rear end side horizontal beam), a second horizontal rod 106, a third horizontal rod 107, and a fourth horizontal rod 108 to form a skeleton as a loading platform. ing. The vertical rods 102a and 102b and the plane formed by these horizontal rods are positioned in a substantially horizontal posture in the traveling form of the folding bicycle 10 and function as a loading platform. Carry attaching portions 109a and 109b are provided inside the curved portions 103a and 103b.

  The first reed 105 (rear end side recumbent) is located at a position adjacent to the rotation axes of the carrys 110a and 110b. In addition, the region formed between the first reed 105 and the second reed 106 is formed between the second reed 106 and the third reed 107 and the second reed 107 so that the user can easily insert the toes. It is formed wider than between the 3 recumbent ridges 107 and the 4th recumbent reeds 108. In the stand form and carrying form of the folding bicycle 10, the first recumbent 105 is located near the ground, and the user can step on the first recumbent 105.

  A pair of carrys 110 a and 110 b (wheels) is attached to the loading platform 100. Carries 110a and 110b are attached to carry attachment portions 109a and 109b. Carries 110a and 110b are located behind the vehicle body in the traveling form of the folding bicycle 10 (see FIG. 1) and are grounded in the stand form and the carrying form (see FIGS. 2 and 3).

  The folding bicycle 10 is provided with a traveling form positioning mechanism 130 and a stand form holding mechanism 140 in order to maintain the traveling form, the stand form, and the carrying form described above. Hereinafter, each mechanism will be described with reference to the drawings.

  As shown in FIGS. 6 and 7, the traveling form positioning mechanism 130 includes a positioning portion 132 formed at an end of the second frame 24 at the rear of the vehicle body, a positioning base 134 provided on the rear wheel frame 72, and a positioning base. And a second locking member 136 attached to 134. The positioning table 134 has a substantially cylindrical shape, and its bottom surface is fixed to a support table 88 provided on the rear wheel frame 72. The positioning portion 132 has a shape in which a cylinder is cut out obliquely, and the bottom surface has a rectangular shape. In the traveling mode of the folding bicycle 10, the stand unit 70 is prohibited from swinging backward at the position where the bottom surface of the positioning unit 132 and the top surface of the positioning table 134 are in contact with each other. Furthermore, the position of the positioning part 132 and the positioning base 134 is locked by positioning the end part of the second lock member 136 in the direction of the positioning part 132. Thereby, as for the folding bicycle 10, a driving | running | working form is maintained.

  As shown in FIG. 7, the stand form holding mechanism 140 includes a locking portion 142 provided on the main frame 20 side and a locked portion 144 provided on the stand portion side. The locking portion 142 is provided with a protrusion 143. In addition, the locked portion 144 is provided with a locking hole 145. As shown to Fig.7 (a), in the driving | running | working form, the latching | locking part 142 and the to-be-latched part 144 will be in the free state. On the other hand, as shown in FIG. 7B, in the stand configuration of the folding bicycle 10, the protrusion 143 is fitted into the locking hole 145, and the locking part 142 and the locked part 144 are locked. Thereby, the folding bicycle 10 can hold | maintain a stand form.

  Next, the configuration of the handle 150 will be specifically described. FIG. 8 is a perspective view of the handle portion 150. The handle portion 150 includes an attachment portion 156 attached to the seat post 27 and a protrusion 152 that protrudes from the attachment portion 156 in a substantially horizontal direction.

  The protruding portion 152 is formed by bending a bar material, and both ends of the bar material are welded and fixed to the mounting portion 156. The protruding portion 152 has a shape protruding substantially horizontally from the mounting portion 156 when attached to the seat post 27, and a grip portion 154 bent upward is formed at an end portion on the protruding side.

  The attachment portion 156 has a substantially cylindrical cylindrical shape and is attached to the seat post 27. A third lock member 158 is attached to the attachment portion 156. When the attachment portion 156 is locked by the third lock member 158, the attachment position and the attachment direction of the attachment portion 156 are fixed. When the lock of the third lock member 158 is released, the attachment position and the attachment direction of the attachment portion 156 can be changed. Thereby, the handle part 150 can be rotated in the circumferential direction with respect to the seat post 27 and can also be moved in the axial direction.

  In the traveling form of the folding bicycle 10, when the grip portion 154 is arranged in a posture facing the rear of the vehicle body, it is possible to hook baggage or the like on the handle portion 150 and use it as a luggage hanging portion. Further, as shown in FIG. 10, in the carrying form of the folding bicycle 10, the direction of the grip portion 154 can be selected according to the convenience of the user.

  Next, the deformation of the folding bicycle 10 from the running form to the stand form and further from the stand form to the carrying form will be specifically described with reference to the drawings.

  As described above, the folding bicycle 10 is configured such that the stand unit 70 can swing integrally. As shown in FIG. 2, when the stand portion 70 is rotated in a direction approaching the front wheel 42 and is rotated to a position where the carrys 110 a and 110 b are grounded, the folding bicycle 10 forms a stand shape. Although not shown in FIG. 2, the locking portion 142 and the locked portion 144 of the stand form holding mechanism 140 are locked. Further, in the stand form, the four places of the carrys 110a and 110b, the rear wheel 74, and the front wheel 42 are grounded to be in a stable state. In the stand form, the folding bicycle 10 is in a state where the longitudinal direction is reduced.

  In the stand configuration of the folding bicycle 10, the center of gravity of the stand unit 70 is located in a region extending from the grounding point of the carrys 110 a and 110 b to the grounding point of the rear wheel 74 in the longitudinal direction. Therefore, the folding bicycle 10 can stand on its own in the form of a stand.

  Next, the operation when the user transforms the folded bicycle 10 from the running configuration to the stand configuration will be described with reference to the drawings. FIG. 9 shows the middle of the operation in which the user deforms the folded bicycle 10 from the running configuration to the stand configuration. As shown in FIG. 9, the user holds and holds the handle 49, hooks his toes on the first reed 105 (rear end side recumbent) and presses the first reed 105 downward with his foot, 70 is swung. In the deformation operation of the folding bicycle 10 into the stand form, the rear wheel 74 rotates while being grounded, and the stand portion 70 swings in a direction approaching the front wheel 42 integrally. When the stand unit 70 swings to a position where the carry 110a, 110b comes in contact with the ground, a stand form is obtained. In the stand configuration, the carrys 110a and 110b are located below the seat tube 26.

  Further, the stand unit 70 is configured to rotate around an axis line (an axis center of the rotating unit 60) extending in a direction along the axle of the rear wheel 74. Therefore, the stand part 70 and the rear wheel 74 rotate in the same direction. Therefore, the entire stand unit 70 can be stably rotated forward of the vehicle body while the rear wheel 74 is grounded and rotated.

  Thus, the user does not need to lift the folding bicycle 10 when the folding bicycle 10 is transformed into the stand configuration, and the user can perform the transformation into the stand configuration by the same operation as operating the stand in a normal bicycle. It can be carried out. As a result, the folding bicycle 10 can be easily transformed into a stand configuration in which the longitudinal direction is reduced while the vehicle body is erected.

  Next, the carrying form of the folding bicycle 10 will be described. FIG. 3 is a side view of the folding bicycle 10 in the carrying form. The folding bicycle 10 is carried by releasing the lock of the first joint portion 30 by folding the main frame 20 from the stand configuration described above, and further releasing the lock of the second joint portion 50 to lower the handle post 48 and the handle 49 downward. It is in the folded state. As shown in FIG. 3, the folding bicycle 10 is folded with the longitudinal direction reduced to substantially the same as the length of the main frame 20 in the carrying form.

  Thus, the folding bicycle 10 in the carrying form is a form suitable for the user to carry the folding bike 10. Moreover, in the folding work which deform | transforms the folding bicycle 10 into a carrying form, the user can perform after making the folding bicycle 10 into a stand form first. For this reason, the overall length of the folding bicycle 10 can be reduced, and can be transformed into a carrying form in a stable state (stand form) by the carry 110a, 110b, the rear wheel 74, and the like.

  Then, the case where a user carries the folding bicycle 10 made into the carrying form is demonstrated. FIGS. 10A and 10B show a state in which the user carries the folded bicycle 10 in the carrying form while towing it.

  In FIG. 10A, the protrusion 152 of the handle 150 is arranged so as to be directed from the seat post 27 toward the rear side in the user's pulling direction. As shown in FIG. 10A, when the user holds the handle 150, the entire body of the folding bicycle 10 is tilted. In this state, the pair of carrys 110a and 110b are grounded, and the front wheel 42 and the rear wheel 74 are not grounded. Moreover, in the operation | movement which pulls and conveys the folding bicycle 10, the gravity center (code | symbol G in a figure) of the folding bicycle 10 is located in the area | region between carry 110a, 110b and a user. Furthermore, the carry 110a, 110b rotates in a direction intersecting the axis of the carry 110a, 110b arranged substantially in parallel, and the folded bicycle 10 can be stably pulled and transported.

  Further, as shown in FIG. 10 (b), it is also possible to arrange the projecting portion 152 from the seat post 27 toward the front of the user in the pulling direction and pull the folded bicycle 10 to carry it. In this case, the portable bicycle 10 can be pulled and transported in the horizontal direction without being tilted, without tilting the body of the folding bicycle 10 that is carried.

  Thus, the folding bicycle 10 can select the direction and position of the protrusion 152 according to the convenience when the user carries the folding bicycle 10.

  Next, a case where the body position of the folding bicycle 10 is held will be described with reference to the drawings. FIG. 11 shows a case where the user holds the vehicle body position while stepping on the first recumbent 105 (rear end side recumbent) of the folding bicycle 10 that is carried. Note that the front wheel frame 40 and the saddle 28 are not shown in FIG.

  As described above, the folding bicycle 10 is positioned such that the first reed 105 and the rotation axes of the carrys 110a and 110b are close to each other. As shown in FIG. 11, in the carrying form of the folding bicycle 10, the first recumbent 105 is located close to the ground. When the user steps on the first recumbent foot 105 in the direction of pressing down with his / her foot, the carry 110a, 110b is pressed downward with the heel in contact with the ground, and the carry 110a, 110b is braked. Thereby, a vehicle body position can be hold | maintained so that the vehicle body of the folding bicycle 10 may not move.

≪When equipped with a three-wheeled carry≫
Next, a modified example in which the carrys 110a and 110b (wheels) of the folding bicycle 10 are changed to the three-wheel carry 210a and 210b will be described. As shown in FIG. 12A, the three-wheel carry 210a, 210b includes a connecting portion 218 including three auxiliary wheels 214a, 214b, 214c and a wheel support portion extending radially in three directions around the central shaft 212. Yes. The auxiliary wheels 214a, 214b, and 214c are arranged such that the wheel shafts 216a, 216b, and 216c, which are the centers of rotation, are positioned at the apexes of the substantially equilateral triangle S. The auxiliary wheels 214a, 214b, and 214c are attached to the connecting portion 218 so as to be rotatable about the wheel shafts 216a, 216b, and 216c, respectively. The connecting portion 218 is attached to the loading platform 100 so as to be rotatable about a central axis 212 located at the center of the substantially equilateral triangle S as a rotation center.

  FIG. 12B shows a traveling form of the folding bicycle 200 to which a pair of three-wheel carry 210a, 210b is attached. As shown in FIG. 12 (b), the three-wheel carry 210 a, 210 b is attached to the rear end portion of the vehicle body of the loading platform 100 in the folding bicycle 200.

  FIG. 13 shows the movements of the three-wheel carryers 210a and 210b when the folding bicycle 200 in the carrying form is transported on a step such as a staircase. In FIGS. 13A, 13B, and 13C, the folding bicycle 200 is pulled in such a direction as to advance to the upper side of the step (“traction direction” in FIG. 13). In FIG. 13, only the three-wheel carry 210a, 210b is shown, and the other configurations of the folding bicycle 200 are omitted.

  FIG. 13A shows a state in which the auxiliary wheel 214c is in contact with the side surface of the step while the two auxiliary wheels 214b and 214c are in contact with the ground. In this state, when a force in the traveling direction is applied to the three-wheel carry 210a, 210b, the three-wheel carry 210a, 210b rotates about the wheel shaft 216c. When the three-wheel carry 210a, 210b rotates about the wheel shaft 216c, as shown in FIG. 13B, the auxiliary wheel 214a contacts the top of the step. When the three-wheel carry 210a, 210b is further pulled in the pulling direction from the state in which the auxiliary wheel 214a is in contact with the top of the step, the three-wheel carry 210a, 210b rotates around the wheel shaft 216a. Then, when the auxiliary wheel 214c is pulled upward along the side surface of the step as shown in FIG. 13C and pulled in the horizontal direction as it is, the step can be raised as shown in FIG. 13D.

  Thus, by adopting the three-wheel carry 210a, 210b, the user can smoothly carry the folded bicycle 200 when carrying it on the stairs. In this way, by using the three-wheel carry 210a, 210b, the folding bicycle 200 can be transported relatively easily at a step such as a staircase.

≪Third embodiment≫
Next, the folding bicycle 300 according to the third embodiment of the present invention will be described. FIG. 14 shows a folding bicycle 300 according to the third embodiment of the present invention. As shown in FIG. 14, the folding bicycle 300 includes a main frame 20, a rotating part 60, a front wheel frame 40 and a stand part 70, a rear wheel frame 72, a cargo bed part 100, and a pair of carries 310 a and 310 b (wheels). . Further, the folding bicycle 300 includes a wheel separation prevention unit 320.

  Note that the main frame 20, the rotating unit 60, the front wheel frame 40 and the stand unit 70, the rear wheel frame 72 and the loading platform unit 100 of the folding bicycle 300 are the main frame 20, the rotating unit 60, the front wheel frame 40, and the like. The structure is the same as that of the stand part 70, the rear wheel frame 72, and the cargo bed part 100. Therefore, in the following description, those having the same configuration as those of the folding bicycle 10 will be described with the same reference numerals as those used in the description of the folding bicycle 10 and will not be described in detail. .

  A pair of carry 310a, 310b (wheel) is earth | grounded in the stand form and carrying form of folding bicycle 300, and assists folding bicycle 300 to become self-supporting with front wheel 42 and rear wheel 74. The carry 310a and the carry 310b are arranged substantially in parallel with a predetermined interval so as to be a target with respect to the axis of the loading platform 100. As shown in FIG. 15, the carry 310a has a first wheel 311a and a second wheel 312a. The first wheel 311a and the second wheel 312a have the same diameter and the same rotation shaft, and are disposed adjacent to each other. The carry 310b has a first wheel 311b and a second wheel 312b having the same diameter and the same rotation axis as the carry 310a.

  As described above, the folding bicycle 300 includes two wheels in each of the pair of carry 310a, 310b arranged at a predetermined interval at the rear wheel 74 side end of the loading platform 100. Thereby, the folding bicycle 300 supports the four bicycle wheels in contact with the front wheel 42 and the rear wheel 74 so that the posture of the folding bicycle 300 becomes independent in the stand form and the carrying form. Therefore, the folding bicycle 300 can maintain a stable and independent posture in the stand form and the carrying form.

  The wheel separation prevention unit 320 is provided to prevent the front wheel 42 and the rear wheel 74 from separating in the carrying form of the folding bicycle 300. The wheel separation prevention unit 320 is attached to the rear wheel frame 72 as shown in FIG. As shown in FIG. 16, the wheel separation preventing portion 320 is a member processed by bending a metal plate, and forms an annular shape partially opened in a side view.
