As shown in FIG. 2 (b), in the folded state, the side of the front wheel 3 on the side where the front wheel fork 7 is provided (the direction toward the back of the paper in FIG. 2 (b)) is the rear wheel 4. A handle stem pipe 10 is disposed on the surface that is directed and not provided with the front wheel fork 7. As shown in FIG. 1, the upper portion of the front wheel fork 7 is inserted into the head pipe 14 from below, and is engaged with the handle stem pipe 10 inserted from above the head pipe 14 in the rotational direction.

  As shown in FIG. 1, the rear wheel fork 8 has a generally triangular shape as viewed from the side. Two vertices on the right side of the paper among the vertices of the triangle are connected to the support portion 15, and the rear wheel 4 is pivotally supported on one vertex on the left side of the paper.

  The bicycle 1 is fixed to a pedal 16, a crank arm 17 that supports the pedal 16 and is pivotally supported below the support portion 15, and a rotation shaft of the crank arm 17 in order to transmit driving force to the rear wheel 4.

The loading platform 35 is configured by combining, for example, a plurality of round bars, and is disposed on the top surface side of the rear wheel 4 so that a load can be placed, and is fixed to the rear wheel fork 8.

  Since the roller 36 is provided on the loading platform 35, the roller 36 is located on the top surface side in the riding state of the rear wheel 4. Naturally, the roller 36 is not grounded in the riding state. Further, as shown in FIG. 2A, the roller 36 is provided on one side of the loading platform 35 and is located at a position shifted laterally from the rear wheel 4. The roller 36 is provided on the support portion 15 side of the loading platform 35.

  As shown in FIG. 2A, in the folded state, the cargo bed 35 and the roller 36 are disposed on the ground side of the rear wheel 4, and the rear end portion 35a and the roller 36 of the cargo bed 35 are grounded.

The rear end portion 35a of the loading platform 35 functions as a stand that supports the bicycle 1, and the roller 36 functions as a stand that supports the bicycle 1 and an auxiliary wheel for rolling.

  The roller 36 is desirably small from the viewpoint of miniaturization, and on the other hand, it is desirable that the roller 36 is large from the viewpoint of smoothly rolling even if the road surface is uneven. Therefore, for example, the diameter of the roller 36 is 50 mm. In the case of a diameter of 50 mm, for example, when the front wheel 3 is 18 inches, it is about 1/9 of the diameter of the front wheel 3, and when the front wheel 3 is 14 inches, it is about 1/7 of the diameter of the front wheel 3. Good balance. There is no conventional folding bicycle provided with a roller of 50 mm or more for rolling wheel. Moreover, it is preferable that the roller 36 is thin from a viewpoint of weight suppression. For example, the thickness of the roller 36 is 4 cm or less.

  The bicycle 1 includes a plurality of folding portions for folding the vehicle body 2 from the riding state shown in FIG. 1 to the folded state shown in FIGS. 2 (a) and 2 (b). Specifically, the first folding part 21 provided between the support part 15 and the rear wheel fork 8, the second folding part 22 provided on the main frame 6, and the first folding part 22 provided on the handle stem pipe 10. 3 foldable portion 23, fourth foldable portion 24 provided between head pipe 14 and handle stem pipe 10, and fifth foldable portion 25 provided between support portion 15 and seat pipe 12. ing.

  The second folding part 22 is configured by a hinge, for example, and can fold the main frame 6 in the lateral direction (y-axis direction).

  The 3rd folding part 23 is comprised by the hinge, for example, and can fold the handle stem pipe 10 in half.

  The fourth folding portion 24 includes an engagement portion (not shown) that engages or releases the handle stem pipe 10 and the front wheel fork 7, and the handle stem pipe 10 so as to tilt the handle stem pipe 10 against the head pipe 14. And a hinge that can fold the head pipe 14.

  The fifth folding part 25 is formed of, for example, a hinge, and the seat pipe 12 and the support part 15 can be folded so that the seat pipe 12 is tilted toward the main frame 6 (forward).

  The second to fifth folding parts are also provided with a lock mechanism (not shown) that restricts the opening operation of the hinge.

  3 to 9 are conceptual diagrams showing a folding procedure of the bicycle 1. 3 to 9, the loading platform 35 and the roller 36 are omitted.

  FIG. 3 shows the boarding state. Note that a ground contact surface defined by the front wheels 3 and the rear wheels 4 in the riding state is GL1. From this state, as shown in FIG. 4, the rear wheel fork 8 is rotated around the first folding portion 21 so as to pass through the ground side, and the rear wheel 8 is above the ground contact surface GL1. The main frame 6 is disposed at a position overlapping with the main frame 6. Note that the chain 19 also rotates together with the rear wheel fork 8 while being hung on the gear 18 and the gear 20.

  Next, as shown in FIG. 5, the frame 6 is folded at the second folding portion 22. The hinge of the second folding part 22 is provided so as to be inclined so that the upper side is forward of the lower side, the front wheel 3 moves above the ground contact surface GL1, and the handle stem pipe 10 is inclined forward. . Further, the front wheel 3 is located behind the rear wheel 4 (on the left side in FIG. 5). Note that a ground contact surface defined by the front wheel 3 and the rear wheel 4 after being folded by the first folding part 21 and the second folding part 22 is defined as GL2. The ground plane GL2 is substantially parallel to the ground plane GL1 with respect to the frame 6, and is located above the ground plane GL1.

  From the state of FIG. 5, as shown in FIG. 6, the engagement of the front wheel fork 7 and the handle stem pipe 10 in the rotational direction is released at the fourth folding portion 24, and the handle stem pipe 10 is rotated 90 degrees. Then, as shown in FIG. 7, the handle stem pipe 10 is folded in half by the third folding portion 23. From the state shown in FIG. 7, the handle stem pipe 10 is folded by the fourth folding part 24 as shown in FIG. 8. As a result, the handle 9 and the handle stem pipe 10 substantially overlap the front wheel 3 and the rear wheel 4.

  Then, as shown in FIG. 9, the saddle 11 is removed from the seat pipe 12, and the seat pipe 12 is tilted forward by the fifth folding portion 25. Further, as shown in FIG. 2A, one of the two crank arms 17 is folded so as to be parallel to the other. The positions of the two crank arms may be either the upper position shown in FIG. 2 (a) or the lower position shown in FIG. 2 (b). However, the upper position shown in FIG.

  FIG. 10 is a side view of the bicycle 1 in the folded state. A rectangle stqr indicated by a solid line is a rectangle including the bicycle 1 with the ground contact surface GL2 as one side when the loading platform 35 and the roller 36 are not provided. As shown in this figure, the rear end portion 35a of the loading platform 35 protrudes from the rectangle stqr. The protruding position is on the opposite side of the front wheel 3 with respect to the rear wheel 4 in the forward / backward direction of the front wheel 3 (left-right direction in FIG. 10). Therefore, the grounding surface of the bicycle 1 is a grounding surface GL3 defined by the front wheel 3 and the rear end portion 35a of the loading platform 35, and the rear wheel 4 is not grounded.

  The roller 36 is in contact with the grounding surface GL3 at a position substantially the same as the grounding position between the front wheel 3 and the grounding surface GL3 in the forward / backward direction of the front wheel 3. Therefore, the roller 36 is grounded and functions as a stand when the rear end 35a of the loading platform 35 is grounded, and can roll with the front wheel 3 with respect to the ground contact surface GL4 when the rear end 35a of the loading platform 35 is lifted. It functions as an auxiliary wheel.

  The rectangle s′t′q′r ′ including the bicycle 1 with the ground contact surface GL3 as one side is preferably set to be approximately the same size as the rectangle stqr. The rectangle stqr and the rectangle s′t′q′r ′ are preferably set to a size that can be stored in a coin locker or the like. For example, the size of the rectangle s′t′q′r ′ is 343 mm × 471 mm. It is.

  FIG. 11 is a schematic view showing a folded state in the case where the rear end portion 35a of the loading platform 35 is lifted and the front wheel 3 and the roller 36 are rolled to perform the wheeling. When rolling, the third folding unit 23 and the fourth folding unit 24 are in a state before folding. As a result, the user can grip the handle 9 and lift the rear end portion 35a side of the loading platform 35 of the bicycle 1 to easily roll the wheel.

  In the following, a specific example of the installation position of the roller 36 will be given, and the positional features that affect the function of the roller 36 when θ1 (θ3) in FIG. A description will be given of an appropriate installation area.

  FIG. 12A is a plan view of the front wheel 3, the rear wheel 4 and the roller 36. When θ1 = 0, the bicycle 1 is supported at the ground point A of the front wheel 3, the ground points B1 and B2 of the rear end portion 35a of the loading platform 35, and the ground point C of the roller 36. As described above, in order to stably support the four grounding points, the position of the roller 36 must be set so that the four grounding points are in the same plane. Whether or not it can be supported by the four contact points depends on the size of the roller 36, the position of the roller 36 in the circumferential direction of the front wheel 3, and the like. Three points may be supported by the grounding points A, B1, C, and the like.

  From the state of being supported at the contact points A, B1, B2, and C, when the rear end portion 35a of the loading platform 35 is lifted and the bicycle 1 is supported at two points by the front wheel 3 and the roller 36, and θ1 is further increased, Both the contact point of the front wheel 3 and the contact point of the roller 36 move to the opposite side (left side of the drawing) of the rear end portion 35a in the x direction. At this time, since the diameter of the front wheel 3 is larger than the diameter of the roller 36, the moving length of the contact point is larger in the front wheel 3.

  Accordingly, as illustrated in FIG. 12A, when θ1 = 0, the front wheel 3 is grounded at the grounding point A, and the roller 36 is grounded at the grounding point C on the left side of the paper surface from the grounding point A. If it is arranged, as θ1 gradually increases, the grounding point of the front wheel 3 approaches the grounding point of the roller 36 in the x direction, and the positions in the x direction are the same at the grounding points A ′ and C ′. Become. When θ1 is further increased, the grounding point of the front wheel 3 is located on the left side of the paper with respect to the grounding point of the roller 36 as in the grounding point A ″ and the grounding point C ″.

  FIGS. 12B to 12D are front views of the front wheel 3, the rear wheel 4, and the roller 36. For example, when the positions in the x direction of the ground point of the front wheel 3 and the ground point of the roller 36 are the same as in the ground point A ′ and the ground point C ′ in FIG. As shown, it is assumed that the roller 36 is attached so that the front wheel 3 and the roller 36 are perpendicular to the ground. In this case, when the rear end portion 35a of the loading platform 35 is moved up and down to increase or decrease θ1, the front wheel 3 is inclined toward the roller 36 as shown in FIG. That is, the inclination α of the front wheel 3 toward the roller 36 increases as the position in the x direction between the contact point of the front wheel 3 and the contact point of the roller 36 increases.

  Further, for example, when the roller 36 is in a position where it is drawn to the rotation center side of the front wheel 3 from the outer periphery of the front wheel 3, the position in the x direction of the grounding point of the front wheel 3 and the grounding point of the roller 36 coincides. However, as shown in FIG. 12B, the front wheel 3 is inclined toward the roller 36, and the angle α is further increased when θ <b> 1 is increased or decreased by raising and lowering the rear end portion 35 a of the loading platform 35.

  On the contrary, when the roller 36 is in a position protruding from the outer periphery of the front wheel 3, when the grounding point of the front wheel 3 and the grounding point of the roller 36 coincide with each other in the x direction, as shown in FIG. In addition, the front wheel 3 is inclined at an angle β on the opposite side of the roller 36, and when θ1 is increased or decreased, the angle β decreases. When θ1 is further increased or decreased, the front wheel 3 becomes perpendicular to the ground as shown in FIG. 12C, and further, the front wheel 3 is inclined toward the roller 36 as shown in FIG.

  State in which the grounding points of the front wheel 3 and the roller 36 are the same in the x direction (see the grounding points A ′ and C ′ in FIG. 12A), or / and the front wheel 3 and the roller 36 are perpendicular to the ground. If rolling wheeling is performed in the state (see FIG. 12C), the operability of rolling wheeling is good. Therefore, from the viewpoint of the operability of the rolling wheel, the position of the roller 36 is set so that the grounding point A ′ and the grounding point C ′ are achieved and the angle α (β) is 0 when the rolling wheeling is performed. It is desirable. For example, in consideration of various conditions such as the height of the handle 9 and the general physique of the user, a value that is most likely to be generated as the magnitude of θ1 (θ3) is specified, and the grounding point at that value is determined. It is preferable to set the position of the roller 36 so that it becomes A ′, the contact point C ′, and the angle α becomes zero.

  FIG. 13 is a conceptual diagram showing a practical installation region R1 that is preferable as the installation position of the roller 36. Each point P0-P4 has shown the grounding point of the roller 36, and the area | region shown by hatching surrounded by the grounding points P1-P4 is practical installation area | region R1.

  The contact point P0 is a geometric theoretical contact point. That is, the position of the roller 36 in the radial direction of the front wheel 3 is set so that the outer peripheral surface 36a of the roller 36 is in contact with the outer peripheral surface 3a of the front wheel 3 and the contact point P0 is in contact with the handle stem pipe 10 in a side view. In the circumferential direction of the front wheel 3 so that the contact point between the outer peripheral surface 36a and the outer peripheral surface 3a is grounded when the angle θ3 formed with the ground surface GL4 becomes a predetermined reference angle θ5 (for example, the angle that is most likely to occur). This is the contact point when the position of the roller 36 is set. Therefore, when the angle θ3 is the reference angle θ5, the contact point P0 of the roller 36 and the contact point of the front wheel 3 coincide in the x direction, and the front wheel 3 and the roller 36 are in front view with respect to the contact surface GL4. It is vertical (seen in the x direction).

  From the viewpoint of the operability of rolling wheel and the like, it is desirable that a grounding point is set at the grounding point P0. On the other hand, various restrictions arise in the installation position of the roller 36. For example, the installation position of the roller 36 must avoid the arrangement position of other parts in both the riding state and the folded state. From the viewpoint of miniaturization in the folded state and aesthetics in the riding state, it is preferable that the roller 36 does not protrude too much.

  In other words, it may be difficult to set a grounding point at the grounding point P0, and conversely, the grounding point P0 is not necessarily an optimal grounding point from a viewpoint other than the operability of rolling wheeling. Is not limited. Accordingly, the installation position of the roller 36 is appropriately selected from the range around the grounding point P0, which is shown as the practical installation region R1.

  The range in the circumferential direction of the front wheel 3 in the practical installation region R1 is, for example, the circumference of the grounding point of the front wheel 3 when the angle θ3 formed by the handle stem pipe 10 and the grounding surface GL4 is in the range of the reference angle θ5 ± dθ. Can be defined by the range of directions. The reference angle θ5 is, for example, 50 °, and dθ is, for example, 20 °. That is, the installation position of the roller 36 is such that the contact point of the roller 35 is within the range of the contact point of the front wheel 3 when the angle between the handle stem pipe 10 and the contact surface GL4 is in the range of 30 ° to 70 °. If it is set to, it is preferable practically.

  The range in the circumferential direction of the front wheel 3 in the practical installation region R1 can be defined by the circumferential length of the front wheel 3. For example, the width W1 on one side can be defined on both sides in the circumferential direction with the grounding point P0 as the center. The width W1 is 5 cm, for example.

  Note that the roller 36 is installed in the circumferential direction of the front wheel 3 mainly when the loading platform 35 side is not lifted in the folded state and the rolling wheel is not moving (θ1 = 0 in FIG. 11). Affects whether it functions as a stand. When importance is attached to the function as a stand, the roller 36 is disposed closer to the grounding points P1 and P4 than the grounding point P0.

  The range in the radial direction of the front wheel 3 in the practical installation region R1 can be defined by the protrusion amount D1 or the pull-in amount D2 from the outer peripheral surface 3a of the front wheel 3. The protrusion amount D1 and the pull-in amount D2 mainly affect the inclinations α and β (see FIG. 12) of the bicycle 1 in the folded state.

  FIG. 14 is a conceptual diagram showing a practical installation region R2 that is preferable as the installation position of the roller 36 in a front view. One of the two crank arms 17 (the crank arm 17 on the left side of the drawing) is provided so as to be movable from the position indicated by the two-dot chain line to the other crank arm 17 side. The position on the left side of the folded bicycle 1 is defined by the crank arm 17. In other words, parts other than the crank arm 17 are relatively easy to dispose inside the crank arm 17.

  Therefore, from the viewpoint of miniaturization in the folded state, the roller 36 is preferably arranged at a position that does not protrude from the crank arm 17, and the practical installation region R <b> 2 extends from the position that does not protrude from the crank arm 17 to the rear wheel 4. Can be defined by range.

  According to the first embodiment described above, the vehicle body 2 is supported while the rear wheel 4 is floated by the front wheel 3 and the roller 36 disposed on the opposite side of the rear wheel 4 from the front wheel 3. Since the front wheel 3 can be rolled, the wheel can be rotated with the crank arm non-rotated in both the front and rear directions, and the chain of the rear wheel 4 and the gear are disengaged. Since no mechanism is required, the configuration is simple.

  Specifically, for example, the roller 36 is provided at a position on the top surface side of the rear wheel 4 in the riding state with respect to the rear wheel 4 and shifted to the side of the rear wheel 4. The main frame 6 is positioned so that the front wheel 3 is positioned on the side opposite to the roller 36 of the rear wheel 4 and the first folding portion 21 that rotates the rear wheel fork 8 so that the top surface side in the riding state is the ground side. The above-described rolling wheel train is realized by providing the second folding portion 22 for folding the frame.

  The roller 36 is grounded when the vehicle body 2 is supported by the front wheel 3 and the loading platform 35 as a stand member, and is provided at a position where the vehicle body 2 is supported by the front wheel 3 and the roller 36 when the loading platform 35 is lifted from the ground. Therefore, the roller 36 functions as an auxiliary wheel for rolling wheeling and also functions as a stand when the rolling wheeling is stopped. Therefore, the number of parts is reduced.

  A roller 36 is provided on the loading platform 35, and in the folded state, the loading platform 35 is grounded at positions B1 and B2 that are shifted from the ground contact point A of the front wheel 3 in the forward and backward direction of the front wheel 3, and functions as a stand. And since the rear end portion 35a side of the loading platform 35 is lifted from the ground and can be rolled by the front wheel 3 and the roller 36, the stand function when the rolling wheeling is stopped is increased in the number of parts. In addition, it is possible to shift from the stopped state to the rolling state only by floating the rear end 35a side of the loading platform 35, and the operation is easy.

Second Embodiment FIG. 15 is a front view showing a main part of a folding bicycle according to a second embodiment of the present invention, and shows a folded state. The schematic configuration of the folding bicycle of the second embodiment is the same as that of the first embodiment, and the same reference numerals as those of the first embodiment are assigned to the same configurations as those of the first embodiment.

  As in the first embodiment, it is desirable that the roller 36 functions as an auxiliary wheel for rolling wheeling and also functions as a stand when the rolling wheeling is stopped. In other words, it is desirable that the roller 36 be grounded both when θ1 = 0 in FIG. 11 and when θ1> 0 (more specifically, when θ3 = reference angle θ5 in FIG. 11). However, when aiming at geometric perfection, it is not easy to set the position of the roller 36 so as to function as an auxiliary wheel and to function as a stand. Therefore, the bicycle according to the second embodiment is designed so that the function as an auxiliary wheel and the function as a stand are both compromised.

  Specifically, as shown in FIG. 15A, when the loading platform 35 is grounded and rolling is stopped, the position of the roller 36 is set so that the roller 36 is not grounded with respect to the ground plane GL3. Set. In other words, the roller 36 is positioned so that the roller 36 is positioned above the grounding surface defined by the grounding points of the front wheels 3 and the loading platform 35 (see the grounding points A, B1, and B2 in FIG. 12A). Set the position.

  However, by setting the gap t1 between the roller 36 and the grounding surface GL3 to be relatively small, the roller 36 is grounded when the bicycle 1 is slightly inclined toward the roller 36 side. That is, the roller 36 is caused to function as an auxiliary stand that prevents the bicycle 1 from falling over. If t1 is shorter than the distance t2 between the rear wheel 4 and the ground contact surface GL3, the fall or the like can be prevented more suitably than when the rear wheel 4 functions as an auxiliary stand. t1 is, for example, within 3 to 4 mm.

  When the position of the roller 36 is set in this way, when the rear end 35a side of the loading platform 35 is lifted, the entire bicycle 1 is inclined toward the roller 36 as shown in FIG. To do. Then, the roller 36 can be rotated while functioning as an auxiliary wheel. However, it is desirable that the inclination α of the front wheel 3 is small in order to ensure the operability of the rolling wheel. For example, α is within 4 to 5 °.

  According to the second embodiment described above, the design condition of the installation position of the roller 36 is relaxed, the roller 36 is made to function as an auxiliary wheel at the time of rolling, and the auxiliary in the state where the rolling wheel is stopped. Can function as a stand.

Third Embodiment FIG. 16 is a side view showing the main part of a folding bicycle according to a third embodiment of the present invention, and shows an enlarged view of the periphery of the bicycle roller 36 in the folded state. The schematic configuration of the folding bicycle of the third embodiment is the same as that of the first embodiment, and the same reference numerals as those of the first embodiment are assigned to the same configurations as those of the first embodiment.

  As shown in FIG. 1, in the folding bicycle 1 of the first embodiment, the roller 36 protrudes from the loading platform 35 to the top surface side. In this case, for example, when a load is to be placed on the loading platform 35, there may be a disadvantage that the roller 36 becomes an obstacle. Therefore, in the third embodiment, a moving mechanism 351 is provided that allows the roller 36 to move between a position where the roller 36 protrudes from the loading platform 35 and a position where the roller 36 does not protrude (a position where the roller 36 sinks from the loading platform).

  The moving mechanism 351 includes a plate 352 in which the groove 355 is opened, a rotating shaft 353 fitted in the groove 355, and a coil spring (biasing means) 354 that biases the rotating shaft 353. The rotary shaft 353 supports the roller 36, and the rotary shaft 353 moves while being guided by the groove portion 355, so that the roller 36 moves between a position P30 protruding from the loading platform 35 and a submerged position P31. .

  Specifically, the groove portion 355 includes a first path 355a that is directed from the position P30 toward the ground plane GL3 at a predetermined angle with respect to the ground plane GL3, and is orthogonal to the first path 355a, and from the first path 355a to the ground plane. A second path 355b extending to the opposite side of GL3, and a second path 355b orthogonal to the second path 355b, a third path 355c extending from the second path 355b to the opposite side of the ground plane GL3, and a third path 355c, The third path 355c includes a fourth path 355d extending toward the ground plane GL3.

  When the rotation shaft 353 is positioned at the position P30, the rotation shaft 353 contacts the upper end side of the first path 355a and receives a bicycle load via the plate 353. Since the first path 355a protrudes toward the top surface with respect to the second path 355b, the rotation shaft 353 is prevented from moving from the first path 355a to the second path 355b during rolling. Note that the angle θ7 is set so that the rotation shaft 353 is prevented from moving from the first path 355a to the second path 355b during rolling (for example, θ3 in FIG. 11 is the reference angle θ5). The first path 355a is preferably provided so as to be orthogonal to the ground.

  The coil spring 354 biases the rotating shaft 353 along the second path 353b toward the first path 353a or toward the position P31 along the fourth path 355d. The movement from the first path 355a to the second path 355b and the movement from the position P31 to the third path 355c are blocked. Thereby, the rotating shaft 353 is more reliably fixed to the position P30 or the position P31.

  According to the third embodiment described above, the roller 36 is provided so as to be movable between a position where the roller 36 protrudes from the loading platform 35 and a position where it does not protrude. While carrying the wheel, it is possible to place the load with the loading surface of the loading platform 35 being flat.

  Further, as shown in FIG. 10, a rectangle s't'q'r 'including a folded bicycle has one side defined by a grounding surface GL3, and the grounding surface GL3 includes the rear end portion 35a of the loading platform 35 and the front wheel. As defined by the ground contact point 3 or the ground contact point of the roller 36, by making the roller 36 movable, it is possible to reduce the size in the folded state. In particular, as in the present embodiment, the rear wheel and the front wheel are arranged on the side of the main frame, and the length between the s ′ and t ′ of the rectangle s′t′q′r ′ is set to the rear wheel and the front wheel. In the folding bicycle that can be made as small as the diameter, the roller 36 can be prevented from obstructing the shortening of the length between s ′ and t ′.

  The moving mechanism for moving the roller may have an appropriate configuration, for example, by providing a rotating shaft at one end, fixed to the rear wheel fork at the other end, and an arm provided rotatably at the other end. Also good.

Fourth Embodiment FIG. 17 is a front view showing an essential part of a folding bicycle according to a fourth embodiment of the present invention, and shows an enlarged view of the periphery of the bicycle roller in the folded state. The schematic configuration of the folding bicycle of the fourth embodiment is the same as that of the first embodiment, and the same reference numerals as those of the first embodiment are assigned to the same configurations as those of the first embodiment.

  In the fourth embodiment, a plurality of rollers having a smaller diameter than the roller 36 are provided instead of the roller 36 of the first embodiment. Specifically, two rollers 451 and 452 that rotate around an axis parallel to the rotation axis of the front wheel 3 are arranged in the circumferential direction of the front wheel 3. In other words, the distance between the roller 452 and the ground plane GL3 is set larger than the distance between the roller 451 and the ground plane GL3 in a state where the rear end portion 35a of the loading platform 35 is grounded.

  When the AR portion (hatched portion in FIG. 17) cannot be spatially secured as a space for installing a roller due to a rear wheel brake or the like, the circumferentially arranged plural rollers are advantageous. It goes without saying that the smoothness of rolling is better with respect to the unevenness of the ground than when there is only one roller.

  Note that FIG. 17 illustrates a case where the rollers 451 and the rollers 452 are floating with respect to the ground surface GL3 with a minute gap in a state where the rear end portion 35a of the loading platform 35 is grounded, as in the second embodiment. However, the roller 451 may be grounded.

  In the folding bicycle of FIG. 17, when the rear end portion 35 a of the loading platform 35 is lifted, the folding bicycle is inclined toward the rollers 451 and 452 (the back side of the paper) as in the second embodiment, and the rollers 451 are grounded. Thereby, rolling by the front wheel 3 and the roller 451 becomes possible.

  Further, when the rear end portion 35a is lifted, the roller 452 is grounded in addition to the roller 451, and rolling by the front wheel 3, the roller 451, and the roller 452 becomes possible. When the rear end 35a is further lifted, the roller 451 moves away from the ground and can be rolled by the front wheel 3 and the roller 452.

  According to the above fourth embodiment, since the plurality of rollers 451 and 452 are arranged in the circumferential direction of the front wheel 3, depending on the inclination when the loading platform 35 is lifted (see angle θ1 in FIG. 11). The grounding roller changes. Therefore, as compared with the case where a single roller is provided, while using a relatively small roller, for example, a roller can be provided so that it can be grounded both at the time of rolling and when the rolling wheel is stopped, The sideways inclination of the bicycle (see angle α in FIG. 12) that changes in accordance with the inclination (θ1) when lifted can be suppressed.

  In addition, size reduction of a roller contributes to the improvement of aesthetics, for example. Further, as shown in FIG. 17, since the protruding amount of the relatively large roller 36 from the loading platform 35 is small with respect to the diameter of the roller 36, in order to pivotally support the roller 36 by the loading platform 35, However, the rollers 451 and 452 are not required if the amount of protrusion from the loading platform 35 is equal to the radius of the rollers 451 and 452.

Fifth Embodiment FIGS. 18 and 19 are views showing a folding bicycle cover (hereinafter simply referred to as “cover”) 501 according to a fifth embodiment of the present invention. FIG. 18 is a side view, FIG. FIG. 19A is a diagram viewed from the upper side of FIG. 18, FIG. 19B is a diagram viewed from the right side of FIG. 18, and FIG. 19C is a diagram viewed from the left side of FIG.

  Since the bicycle housed in the cover 501 of the fifth embodiment is, for example, the bicycle of the first to fifth embodiments, the same reference numeral as that of the first embodiment is assigned to the bicycle housed in the cover 501. Attached. In the following description, the vertical direction in FIG. 18 is described as the vertical direction of the cover 501 for the sake of convenience.

  The cover 501 includes a bag portion 502 and a shoulder belt 503. The bag portion 502 is made of a flexible material such as vinyl, and is formed in a rectangular parallelepiped size that can accommodate the entire folded bicycle 1. Two shoulder belts 503 are provided on the surface 502e so that the backs of the shoulder belts 503 can be brought into contact with the side surfaces 502e of the front wheels 3 and the rear wheels 4, respectively. By supporting the side surfaces of the front wheel 3 and the rear wheel 4 on the back, a relatively wide area can be secured as a contact area with the back, and the back can be stably supported. An elastic member 504 made of sponge or the like is disposed on the surface 502e from the viewpoint of protecting the user's back and the bicycle 1.

  The shoulder belt 503 is provided so as to extend in the forward / backward direction of the front wheel 3 and the rear wheel 4 (the left-right direction in FIG. 19A). As shown in FIG. 10, the length between s ′ and t ′ of the rectangle s′t′q′r ′ including the bicycle 1 is substantially equal to the diameters of the front wheel 3 and the rear wheel 4, and s′−r. Is longer than the length between s ′ and t ′ by the amount of displacement of the front wheel 3 and the rear wheel 4, the shoulder belt 503 is provided so as to extend in the longitudinal direction of the bag portion 502. As a result, the user can carry the bag portion 502 stably.

  Fasteners 508 are provided over the entire circumference of the bag portion 502 on the ground contact surface side of the front wheel 3 and the rear wheel 4 of the bag portion 502, and the bag portion 502 can be separated into an upper cover 502a and a lower cover 502b. is there. In other words, the lower cover 502b is detachably provided, and the bicycle 1 can be rolled while the upper cover 502a is placed on the bicycle 1 by removing the lower cover 502b.

  The position of the fastener 508 in the vertical direction on the paper surface of FIG. 18 may be set as appropriate. However, since the rear wheel 4 side (the right side on the paper surface) is lifted during rolling wheeling, it depends on the assumed inclination so that the front wheel 3 side (the left side on the paper surface) of the upper cover 502a does not touch the ground. It is preferable to set the height.

  As shown in FIGS. 19 (a) and 19 (b), the bag portion 502 has an opening 505 at the intersection between the surface of the front wheel 3 in the advancing / retreating direction (right side of the drawing in FIG. 19 (a)) and the upper surface. Open. Further, as shown in FIGS. 19A and 19C, the bag portion 502 is provided with a fastener 506 extending over the upper surface of the bag portion 502 and the side surface opposite to the opening 505. . The fastener 506 is continuous with the opening 505. Accordingly, with the fastener 506 opened, the handle stem pipe 10 is protruded from the opening 505 and the bicycle 1 is stored in the bag 502, and then the fastener 506 is closed, as shown in FIG. The handle stem pipe 10 can be gripped and rolled. In addition, a pulling string for rolling wheel is provided on the cover 501, and rolling wheeling may be performed by pulling the pulling string.

  According to the fifth embodiment described above, it is formed in a rectangular parallelepiped size that can accommodate the entire folded bicycle 1, and the back is brought into contact with the lateral surfaces of the front wheel 3 and the rear wheel 4 to carry the back. Since the shoulder belt 503 is provided and the lower cover 502b is detachable, the bicycle 1 can be carried on the back of the bicycle 1, or the lower cover 502b can be removed for rolling. Since the shoulder belt 503 is provided so that the back is in contact with the sides of the front wheel 3 and the rear wheel 4, the shoulder belt 503 can be stably carried on the back. The shoulder belt 503 is attached only to the upper cover 502a, and the lower cover 502b is positioned on the side when it is carried on the shoulder. Therefore, the load applied to the fastener 508 is relatively small when carried on the back, which is advantageous in terms of strength. is there. In public transport, bare luggage (bicycles) is not allowed for safety to other passengers. However, the upper cover 502a or the like serves as a bag and does not hinder transportation on a train or the like.

  The present invention is not limited to the above embodiment, and may be implemented in various aspects.

  The two-wheeled vehicle is not limited to a bicycle as long as it has two wheels, a front wheel and a rear wheel. For example, the driving force may be obtained by an internal combustion engine or an electric motor.

  Also, the deformation between the riding state and the folded state is not limited as long as the vehicle body is folded so that the front wheels are arranged on the sides of the rear wheels, and the rear wheels are folded so as to pass through the ground side. The folding is not limited to the front wheels moving sideways. For example, the front wheel may be folded so as to pass through the top surface or the ground side, or the rear wheel may be folded so as to move to the side.

  The wheeling auxiliary unit may be any one that comes into contact with the ground when rolling the front wheel. Therefore, the wheeling auxiliary part is not limited to the roller, and for example, the wheeling auxiliary part may be constituted by a sliding plate that slides with respect to the ground. Moreover, it does not need to function as a stand when the rolling wheeling is stopped, and the place where the wheeling auxiliary part is provided is not limited to the loading platform.

  The stand member is not limited to a loading platform as long as it can support the vehicle body by the front wheels and the stand member in the folded state. For example, the rear wheel may be used as a stand member.

  The plurality of auxiliary wheels arranged in the circumferential direction may not be arranged with the same curvature as the circumference of the front wheel. When three or more are arranged, it can be said that they are arranged in the circumferential direction as long as they are arranged in an arc shape having a concave on the rotation axis side of the front wheel. In the case where two wheels are arranged, the distance between one auxiliary wheel and the ground contact surface is the same as that of the other auxiliary wheel in a state where the rolling wheeling is stopped, for example, in a state where it is supported by the front wheel and the stand member. If it is farther than the distance from the ground plane, it can be said that it is arranged in the circumferential direction. In any case, when the tilt of the folded bicycle is changed, the tilt of the bicycle can be suppressed by changing the auxiliary wheel to be grounded.

  The two-wheeled vehicle may be a front-wheel drive type. In this case, the wheeling auxiliary portion may be disposed on the opposite side of the rear wheel with the front wheel in the folded state so that the front wheel can be lifted and rolled by the rear wheel. For example, a loading platform may be provided on the top side in the riding state of the front wheels, and a wheeling auxiliary portion may be provided on the loading platform.
