Description

M344202 VIII. New description [New technical field] This creation is about fenders, especially the fenders that can be installed on bicycles. [Prior Art] A bicycle is mainly provided with a fender bent into a semicircular arc shape on the outer peripheral side of the rear wheel of the utility vehicle. At the rear of the fender, a mirror for ensuring visual confirmation from the rear is provided at night. On the other hand, in order to improve the visibility from the rear of the bicycle, a tail light having a light source is known. A conventional taillight for a bicycle is, for example, a front end of a seat cushion or a rear carrier mounted on a bicycle, which is turned on or off depending on the rotation of a magnet mounted on the spoke, or by a power source or a generator from a battery or the like. The power is turned on or off. [New content] [Question to be solved by the author] When the taillight is installed in the utility vehicle, when the taillight is installed at the position of the mirror of the fender, the mirror is placed at a lower position than the fender. Therefore, it is not easy to ensure the visibility of the car and the like from the rear. When the tail light is attached to the fender, the tail light protrudes and is not conducive to the design of the new style, and the protruding portion is easily broken. In particular, for sports cars such as mountain bikes (MTB), the appearance is significantly impaired and the possibility of breakage is higher. The subject of this creation is that for the bicycle fender, even if the tail light is attached to the mud guard -4- M344202, the visual confirmation can be ensured, and the new style effect is improved and the damage is not easy. (means to solve the problem)

The fender for bicycles of Creation 1 is a fender that can be mounted on a bicycle, and has a mounting portion, a fender body, and a taillight. The mounting section is detachable for the frame of the bicycle. The fender body extends in a direction away from the mounting portion. The tail light is a light source having a front end portion that is built in the body of the fender. In this fender, the fender body extends from the mounting portion. Here, the light source of the taillight is built in the front end. Here, since the fender body extends from the mounting portion, the front end portion can be disposed at a relatively high position. Since the light source of the tail light is built in the front end portion, the position of the tail light can be increased. Therefore, the visibility from the rear can be sufficiently ensured. Moreover, because of the built-in light source, it is possible to suppress the protrusion of the tail lamp and improve the new style effect of the fender, and it is not easy to cause damage caused by the protrusion. The fender for bicycles of the creation 2 is a fender of the creation 1, and the mounting portion is a pipe member that can be attached to the saddle that constitutes the frame. In this case, since the pipe member for mounting the saddle such as the seat tube or the seat cushion of the frame can be attached to the attachment portion, the fender is easily attached later, and since it is attached only to one portion of the pipe member, Installation work is also easy. The fender for bicycles of the creation 3 is a fender that creates 1 or 2, and the mounting portion is a power supply box having a power source for the tail light. This kind of situation -5- M344202 The 8 fender for bicycles is the fender of the creation of 7, and the taillight is disposed at the front end of the skeleton, and the cover is detachable for the skeleton. In this case, since the cover portion that can function as a fender is removed, the cover portion is installed when the function of the fender is required, and the overall weight of the bicycle can be reduced. [Creation effect]

According to the present creation, since the fender body extends from the mounting portion, the front end portion can be disposed at a relatively high position. Since the light source of the tail light is contained in the front end portion, the light-emitting position of the tail light can be improved. Therefore, the visibility from the rear can be sufficiently ensured. Moreover, since the light source is built in, the protrusion of the tail light can be suppressed and the new style effect of the fender can be improved, and the damage caused by the protrusion is less likely to occur. In particular, for a sports car such as an MTB, a fender can be installed without impairing the appearance. [Embodiment] In the first embodiment, a bicycle according to an embodiment of the present invention is a mountain bike, comprising: a frame body 2 including a rear suspension 13r, and a front fork 3 and a handle portion 4 with a front suspension 13f.

In the battery mounting portion 12c, at least one (e.g., two) batteries 12d may be mounted. The battery 1 2d is a primary battery such as a dry battery or a rechargeable secondary battery. The tail light 42 has a tail light housing 42a integrally formed on the fender 丨6 (Fig. 1), and a light source 42b composed of at least one (for example, three) LEDs (light emitting diodes) 42c housed in the tail light housing 42a. The tail light 42 is turned on and off (ON/OFF) by the switch unit 12b. The LEDs 42c are connected in parallel in this embodiment. However, the connection form of the LEDs 42C is not limited to being arranged in parallel, and may be connected in series. As shown in FIG. 3, the fenders 16 are provided with a mounting portion 30 that is detachably attached to the seat tube 2 (an example of a piping member) 2a of the frame body 2, and a mounting portion 30 that faces away from the mounting portion 30. The fender body 3 1 extending in the direction and the tail light 42 having the light source 42b built in the front end portion (the rear end portion of the third figure) of the fender body 31 are provided. The fenders 16 may be disposed above the rear wheel 7, but are different from the conventional fenders and do not extend to the rear end -9 - M344202 of the rear wheel 7. Specifically, the fenders 16 are extended to a position slightly rearward of the axle of the rear wheel 7. When the fender 16 extends beyond the rear axle, it is easy to prevent the horse from scattering even if the mud or the like splashes from the rear wheel 16 .

The mounting portion 30 is, for example, a substantially U-shaped metal member having a power supply device 12. Further, the mounting portion 30 has a bracket 30a for providing the power supply unit 12 at the front end (the right end of Fig. 3) of the U-shaped bottom. The bracket 3〇a is formed by bending the two ends facing each other and holding both ends of the power supply box 12a. Further, the mounting portion 30 has a mounting hole 30b at the center portion through which the cushion tube 2a can pass. A slit 30c is formed around the mounting hole 30b. In order to narrow the slit 30c, the fender 16 is fixed to the cushion tube 2a, and the two fixing screws 30d are arranged in a direction intersecting the slit 30c. The fender body 31 is a plastic molded article such as polypropylene. As shown in Fig. 4, the fender body 3 1 has a thick layer of the skeleton portion 3 1 a and a lid portion 3 1 formed integrally with the skeleton portion 3 1 a. b. The skeleton portion 31a is a portion that receives the strength of the fender body 31, and is slightly curved upwardly from the mounting portion 30 to the arrangement portion of the tail light 42. In the center portion of the skeleton portion 3 1 a, a wiring insertion hole 3 1 c formed to have a length from the mounting portion 30 to the arrangement portion of the tail light 42 is formed. The wiring insertion hole 3 1 c is provided to allow the wiring 34 for connecting the power source device 12 and the tail lamp 42 to be inserted. The wiring insertion hole 3 1 c is formed by inserting a piping material 3 formed of, for example, a light alloy such as aluminum into the mold at the time of molding the fender body 31. The strength of the fender body 31 can also be ensured by the piping 3 5 . The cover portion 3 1 b is formed to extend rearward from the mounting portion 30 when the fender 16 is mounted on the bicycle, and is covered above the -10-M344202 wheel 7. The lid portion 3 1 b is formed by bending a cross section (fourth drawing) in a direction crossing the longitudinal direction from the both sides of the skeleton portion 31a.

The tail light 42 has a tail light housing 42a as described above and a light source 42b including three LEDs 42C. The tail light housing 42a is integrally formed at the front end portion of the skeleton portion 31a of the fender body 3 1 as shown in Figs. 5 and 6, so that the contour is smoothly prevented from protruding from the fender body 31. connection. The tail light housing 42a is an opening 42f having an elongated curved shape in the lateral direction which is opened rearward. Three storage tube portions 42d are formed on the upper surface of the tail lamp housing 42a at intervals, and three LEDs 42C as the light source 42b can be housed separately. Each of the LEDs 42C of the light source 42b is, for example, white light. Further, the tail light 42 further has a lens portion 42e for diffusing light from the light source 42b. The lens portion 42e is made of, for example, a red translucent synthetic resin, and is formed by bending the opening 42f. As shown in Fig. 6, a plurality of pointed uneven portions 42g having a quadrangular pyramid shape are formed on the inner side surface of the lens portion 42e, and the light is cooled to an angle α in the upward direction and an angle in the downward direction of the optical axis X of the light source 42b. The scope spreads. With the uneven portion 42g, the light is, for example, an angle α of 25 degrees with respect to the optical axis X, an angle Θ of 20 degrees, and a range of 45 degrees as a whole. Since the light from the light source 42b is also diffused upward above the optical axis X, the visibility of the vehicle which is relatively high from a driver such as a large car or an RV car is also improved. The fender 16 of this configuration is mounted on the frame 1 of the bicycle by the following procedure. When the fender 16 is installed, the seat post 2b (including the saddle 18) -11 - M344202 and its fixing clasp are removed, and the seat post 2b is exposed to the outer peripheral surface of the cushion tube 2a.

Further, the fender 16 is fixed to the frame 1 by tightening the fixing screws 3 Od at a suitable height position.

When the fender 16 is attached to the bicycle, the fender body 31 is disposed above the rear wheel 7, and the tail lamp 42 is disposed slightly rearward of the axle of the rear wheel 7. Here, since the fender body 3 1 extends rearward from the mounting portion 30, it can be disposed at a position higher than the front end portion of the fender body 1. Since the light source 42b of the tail light 42 is housed in the front end portion, the light-emitting position of the tail light 42 can be increased. Therefore, it is possible to sufficiently ensure visual confirmation from the rear. Further, since the light source 42b is built in, it is possible to suppress the protrusion of the tail lamp 42 and improve the new effect of the fender, and it is less likely to cause damage due to the protrusion of the tail lamp 42. Further, since the mounting portion 30 of the fender 16 can be attached to the seat tube 2a as the piping member for mounting the saddle 18, it is easy to add the fender 16 later, and since it is only attached to the piping member It can be done in one place, so installation work is easy. Further, since the power supply unit 12 that is the power source of the tail light 42 is provided in the mounting portion 30, only the fenders 16 are installed to secure the power of the tail lamps 42. And because the power supply uses a battery, wiring is not required. In the present embodiment, the tube portion 35 is included in the wiring insertion hole 3 1 c. However, the wiring insertion hole 3 1 c may be a through hole only. -12 - M344202 [Other Embodiments] (a) In the foregoing embodiment, the light source of the tail light is an LED having a long service life and low power consumption, but the power source is not limited to the LED, and any light source such as a bulb may be used. .

The first recessed portion 1 3 1 e has a shape that engages with the lower surface of the piping portion of the skeleton portion 1 3 1 a. In the distal end side (the left end side of the seventh drawing) and the proximal end side (the right end side of the seventh drawing) of the first recessed portion 1 3 1 e, an arc-shaped one-pair locking that holds the first recessed portion 1 3 1 e is formed. Part 1 3 1 f, 1 3 1 f. The bone portion 1 3 1 a is held between the locking portions 1 3 1 f and 1 3 1 f so that the lid portion 1 3 1 b is detachably fixed to the skeleton portion 1 3 1 a. On the distal end side (the left side in Fig. 7) of the first concave portion 1 3 1 e, a second concave portion 131g for engaging the lower surface of the tail light 1 42 is formed. The second concave portion 131g has a shape that can be engaged with the bottom surface of the tail light 142 when the lid portion 13 lb is attached to the skeleton portion 13 la, that is, a shape that is integrated with the tail light 144. Further, the power supply unit 1 1 2 provided in the mounting portion 130 is connected to the hub generator 1 by the headlights 41 as shown in Fig. 8. Therefore, the battery is not housed as in the above embodiment. Inside the power supply device 1 12, a voltage holding circuit 112a that limits the power generation voltage of the drum generator 1 to a predetermined voltage or lower (for example, 5 volts or less) is accommodated. The light source 142b of the tail light 142 is configured by connecting two groups of LED groups having different polarities of two LEDs 142c and 142d in parallel. In this connection mode, two sets of LEDs 142c and 142d may be connected in series. Here, the two LEDs 142c and 142d have different polarities and can be used without rectifying the AC power. -14- M344202 The cover portion 1 3 1 b which has the function of the fender is removed from the skeleton portion 1 3 1 a, so that the cover portion 1 3 1 b is removed when the function of the fender is not required, The overall weight reduction of the bicycle can be achieved. (c) In the above-described embodiment, the mounting portions 30 and 130 may be attached to the cushion tube 2a as the piping member for saddle mounting, but the mounting portions 30 and 130 may be attached to the seat post 2b. In this case, since the fender can be attached only by removing the seat post 2b, the fender is easier to handle.
