  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bicycle having improved safety during traveling by solving the above problems and improving visibility from the rear without impairing riding comfort.

  As a result of intensive studies, the present inventors have found that the above problem can be solved by adopting the following configuration, and have completed the present invention.

  That is, the present invention is a bicycle including a storage box at the rear of the vehicle body from the seat tube, and the width of the storage box in the axle direction is gradually widened toward the rear of the vehicle body.

  In the bicycle of the present invention, it is preferable that the width of the storage box in the axle direction is substantially the same as the width of the seat tube or the top tube in the vicinity of the seat tube. In the bicycle of the present invention, it is preferable that the storage box has an illumination part on a side part facing the rear of the vehicle body. In this case, preferably, the illumination unit includes a direction indicator. Furthermore, in the bicycle of the present invention, it is preferable that the storage box is continuously provided on the top tube. Furthermore, the bicycle of the present invention preferably has a tire size of 24 inches.

  According to the present invention, by adopting the above-described configuration, it is possible to realize a bicycle with improved safety during traveling by improving visibility from the rear without impairing riding comfort.

It is the perspective view which looked at the storage box from back diagonally upward. It is the front view which looked at the storage box from the bicycle back. It is explanatory drawing which shows the relationship between the angle of an imaging device, and the area | region which can be image | photographed with an imaging device. It is a side view of the bicycle concerning other suitable embodiments of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a side view of a bicycle according to a preferred embodiment of the present invention. The illustrated bicycle 1 includes a seat tube 3 that supports a saddle 2 and a head tube 5 that supports a handle 4. Yes. In the illustrated example, the upper portion of the seat tube 3 and the upper portion of the head tube 5 are connected via the top tube 6, and the bottom bracket shell 7 is disposed at the lower portion of the seat tube 3. The lower tube and a down tube 8 extending from the lower portion of the head tube 5 are connected via a bottom bracket shell 7. Further, in the illustrated example, the chain stay 9 extends from the bottom bracket shell 7, and the seat stay 10 extends from a substantially central portion of the seat tube 3 toward the mounting position of the bicycle rear wheel 11.

  As shown in the figure, the bicycle 1 of the present invention includes a storage box 12 at the rear of the vehicle body from the seat tube 3. FIG. 2 shows a plan view of the storage box as viewed from above. FIG. 3 is a perspective view of the storage box as viewed obliquely from the upper left, and FIG. 4 is a front view of the storage box as viewed from the rear of the bicycle. As shown in FIGS. 3 and 4, the storage box 12 has illumination parts 13, 14 a, 14 b on the side part 12 </ b> A facing the rear of the vehicle body.

  As shown in FIG. 2, the bicycle of the present invention is characterized in that the width of the storage box 12 in the axle direction is gradually widened toward the rear of the vehicle body (the left direction in FIG. 1). The storage box 12 arranged at the rear of the vehicle body from the seat tube 3 has a shape widened toward the rear of the vehicle body, thereby ensuring visibility when the bicycle is viewed from the rear by the side surface portion 12A at the rear of the vehicle body. However, the front portion of the storage box 12 close to the saddle 2 has a width approximately equal to the diameter of the seat tube 3, thereby preventing the driver's legs from interfering with the storage box 12 during pedaling. . As a result, it has become possible to realize a bicycle with improved safety during running without impairing riding comfort. Further, in the present invention, the storage box 12 does not change sharply in the axle direction, that is, is formed in a shape having no corners, so that when something is stored in the storage box 12 However, the concentration of stress can be suppressed, the strength can be improved, and even if the storage box 12 comes into contact with an obstacle such as a branch during traveling, the mounting position of the storage box 12 is changed or the storage box 12 is damaged. The effect that it can suppress can also be acquired.

  The storage box 12 only needs to have a width in the axle direction that is widened toward the rear of the vehicle body, and the specific shape thereof is not limited to a substantially trapezoidal shape as illustrated. Further, the specific dimensions are not particularly limited as long as they do not depart from the spirit of the present invention. For example, the width in the vicinity of the seat tube may be substantially the same as the width of the seat tube or the top tube. On the other hand, the width of the widest portion can be set to the same width as a general-purpose bicycle carrier (carrier).

  The storage box 12 according to the present invention includes, for example, a light source, an electrical battery, and the like inside, unlike a case for a user to store luggage. More specifically, the illustrated storage box 12 includes, on the side surface 12A, illumination units 14a and 14b that function as direction indicators together with an illumination unit 13 that functions as a taillight. These illumination parts 13, 14a, 14b are constituted by a light source such as a light emitting diode (LED, Light Emitting Diode) incorporated in the storage box 12, and a cover material 15 made of a transparent or translucent resin material, etc. When the light from the light source is irradiated to the outside through the cover member 15, it functions as a taillight or a direction indicator. In the illustrated example, the rhombus-shaped illumination unit 13 and the arrow-shaped illumination units 14a and 14b are arranged on the side surface portion 12A of the storage box 12 so as not to be adjacent to each other at a predetermined interval in the width direction. There is an advantage that it is easy to distinguish when the tail lamp is lit and when the direction indicator is lit. In addition, the illumination units 14a and 14b functioning as direction indicators are formed in the shape of arrow feathers that respectively indicate both sides in the vehicle width direction. In the illustrated example, the tail lamp 13 has a rhombus shape because the direction indicators 14a and 14b arranged on both sides of the tail lamp have an arrow feather shape and visibility from the rear of the bicycle 1. This is because the light emitting area of the tail lamp 13 is increased.

  As shown in the drawing, the present invention is particularly useful when the storage box 12 includes a direction indicator as an illumination unit. That is, in order to provide the storage box 12 with a direction indicator that can ensure sufficient visibility even from a position some distance from the bicycle, it is necessary that the storage box 12 has a certain width in the axle direction. This is because if the storage box 12 has a width, the storage box and the driver's leg can easily come into contact with each other during pedaling. In the present invention, as shown in FIGS. 3 and 4, even when the taillight and the direction indicator are built in the storage box 12, riding comfort during pedaling is not impaired.

  In the present invention, the storage box 12 is preferably provided continuously to the top tube 6 as illustrated. The storage box 12 can obtain the effects of the present invention as long as it is arranged behind the seat tube 3 from the vehicle body. However, from the viewpoint of further improving the visibility from the rear, the storage box 12 is as close to the saddle height as possible. This is because it is preferable to dispose them. In addition, although the storage box 12 may be integrally formed using the same kind of material as the seat tube 3 and the top tube 6, a part or the whole of the storage box 12 is formed of another material and joined. There is no particular limitation.

  In the illustrated bicycle according to the preferred embodiment of the present invention, an imaging device 16 that captures the rear is fixed to the right side in the bicycle traveling direction on the lower surface of the storage box 12, and an image captured by the imaging device 16 is displayed on the handle 4. A monitor 17 for projection is attached. Accordingly, the driver can drive the bicycle while checking the rear image of the bicycle photographed by the imaging device 16 on the monitor 17, so that it is easy to check the safety of the rear, and safety during driving. It becomes possible to improve the property.

  In this case, as shown in the drawing, it is preferable to incline the shooting direction of the imaging device 16 so that only the right rear side is shot with respect to the bicycle traveling direction. Here, the right side with respect to the traveling direction of the bicycle means the right side as viewed from the driver in a state in which the driver is on the bicycle. This is because the bicycle passes on the left side of the driving lane and does not change the driving lane like cars and motorcycles. This is because video is important. In addition, since the imaging direction of the imaging device 16 is inclined to the right rear, the monitor 17 displays an image captured centering on the right rear of the bicycle 1, so that the driver can It can be said that the effect of urging the left side running 1 is also obtained. Specifically, the imaging surface of the imaging device 16 is tilted to the right in the bicycle traveling direction at an angle θ of 10 ° to 15 ° with respect to the direction opposite to the traveling direction of the bicycle 1, It is preferable to incline at an angle of 10 ° to 15 ° from right behind the driver of the bicycle 1 to the right. This angle is preferably 12 ° ± 1 °. As a result, a vehicle traveling on the right rear side of the bicycle can be satisfactorily captured by the imaging device. FIG. 5 is an explanatory diagram illustrating the relationship between the angle of the imaging device and the area that can be captured by the imaging device. In the example shown in the figure, the bicycle 1 is traveling on the left end of the traveling lane on the left side of the road of two lanes on one side, and the automobiles 20a and 20b are traveling on the traveling lane 18 and the overtaking lane 19 about 10m behind the bicycle 1. doing. Note that 10 m is a distance corresponding to two passenger cars.

  If the shooting direction of the imaging device 16 is the direction opposite to the traveling direction of the bicycle 1, the region shot by the imaging device 16 is a region A in the figure. Therefore, the monitor 17 displays only the image of the area A, that is, the automobile 20 a traveling in the traveling lane 18, and the driver of the bicycle 1 cannot notice the automobile 20 b traveling in the overtaking lane 19. Therefore, in the bicycle 1 of the present invention, the shooting direction of the imaging device 16 is preferably 10 ° to 15 °, preferably 12 ° ± 1 ° to the right with respect to the direction opposite to the traveling direction of the bicycle 1. Tilt and shoot area A and area B together. Thereby, since the automobile 20b traveling on the overtaking lane 19 can also be captured in the image, safety can be improved.

  Here, the closer the installation position of the imaging device 16 is to the driver's viewpoint, the closer it is to the case where the driver confirms the rear with his own eyes, which is preferable. Therefore, the vertical position of the image pickup device is preferably higher than the upper end of the rear wheel 11, and the position of the image pickup device in the front-rear direction of the bicycle traveling direction is preferably near the rear end of the saddle 2. Here, in the illustrated example, the vicinity of the rear end of the saddle 2 is a range in which the storage box 12 including the imaging device 16 and the saddle 2 overlap in the vertical direction. In the present invention, more preferably, the position of the imaging device 16 is made to coincide with the rear end of the saddle 2, and the imaging device 16 and the rear end of the saddle 2 are overlapped in the vertical direction (see FIG. 1).

  Further, the imaging device 16 may be installed at any position on the rear side of the bicycle as long as the rear of the bicycle 1 can be photographed, but is preferably attached to the storage box 12 as illustrated. . By fixing the imaging device 16 to the storage box 12, the shooting obstacles are minimized when the imaging device 16 captures the right rear with respect to the bicycle traveling direction. In this case, there is no particular problem even if the imaging device 16 is attached to the center in the width direction at the rear of the storage box 12, the left side of the bicycle traveling direction, or both the left and right sides. Therefore, as shown in the drawing, it is preferable to attach the storage box 12 only to the right side in the bicycle traveling direction. In the illustrated example, the imaging device 16 is attached to the lower side of the storage box 12, but may be attached to the upper side of the storage box 12, or may be embedded in the storage box 12. There are no particular restrictions on the location of attachment in the vicinity of the storage box 12.

  The imaging device 16 used in the present invention has a size and weight that can be installed on a bicycle, and can be attached to the bicycle as described above to photograph the back of the bicycle. A general video camera or the like can be used, and the specific structure and the like are not particularly limited. Further, the monitor 17 is not particularly limited as long as it can display the video imaged by the imaging device 16.

  In this case, the battery for electrical equipment can be used as a power source for various electrical equipment included in the bicycle 1 such as the imaging device 16 and the monitor 17 in addition to lighting fixtures such as tail lights and turn indicators. When an electrical equipment battery is arranged in the storage box 12, power supply from the electrical equipment battery in the storage box 12 to the monitor 17 can be achieved by running a power cable (not shown) along the top tube 6. Alternatively, it is possible to connect the power cable to the monitor 17 by providing a hole through which the power cable is passed inside the top tube 6 and passing the power cable through the hole.

  In the bicycle 1 of the present invention, the frame structure and the material thereof are not particularly limited, and a known frame structure and material can be appropriately selected and used.

  For example, the bicycle of the present invention has a frame shape in which a top tube mainly for male users and a head tube shown in FIG. 1 intersect, and a top tube 36 mainly for female users and a down tube 38 shown in FIG. It is also possible to use a frame shape. By adopting the latter frame shape, it is possible to easily get on and off the bicycle when the driver wears a skirt or the like. Here, the bicycle 31 shown in FIG. 6 has the same structure as the bicycle 1 shown in FIG. 1 except that the top tube 36 intersects the down tube 38 instead of the head tube 35. In the figure, 32 is a saddle, 33 is a seat tube, 34 is a handle, 37 is a bottom bracket shell, 39 is a chain stay, 40 is a seat stay, 41 is a rear wheel, 42 is a storage box, 46 is an imaging device, 47 Indicates a monitor, respectively.

  The bicycle of the present invention preferably has a tire size of 24 inches. As a result, it is possible to provide a bicycle in which the storage box and the space for arranging the imaging device in the illustrated example are further secured between the saddle and the tire, and the speed performance during commuting is also secured.
