Description

  The present invention relates to an EL light-emitting device attached to a bicycle and a bicycle including the same.

  In general bicycles, a reflection sheet and a reflection plate are attached to a frame and a rear fender as items for ensuring safety in a dark place.

  These reflection sheets and reflection plates are easy to configure and attach, and hardly interfere with driving or pushing the bicycle (the user gets down from the saddle and walks).

  On the other hand, these reflective sheets and reflectors cannot emit light (shine) by themselves, but shine only after reflecting light from automobile headlights, etc., thus ensuring safety in dark places and preventing crime. The performance is not always sufficient.

  As a means for solving such a drawback, devices using EL (electroluminescence) are disclosed in Patent Documents 1 and 2, for example.

  Among these, the EL light emitting device of Patent Document 1 includes a transformer (driving unit) connected to a bicycle generator having a light, and an EL element connected to the secondary side of the transformer. The light and the EL element are turned on.

  According to the EL light emitting device disclosed in Patent Document 1, the entire EL element is in the form of a flexible cable. Therefore, when the bicycle is running at night, the EL element has a wide range with respect to the front, side, back and diagonal directions of the bicycle. It is said that it is possible to emit light and to effectively alert a third party.

  The EL element may be a plate-like element, and in this case, it can be provided on the surface of the chain cover, for example.

  On the other hand, in the EL sticker device of Patent Document 2, a transformer (driving unit) connected to an AG power source (AC power source) and a plurality of EL stickers are further connected, and the EL sticker is attached to an appropriate place of a bicycle (a bicycle body or tire Cover).

  According to the EL sticker device of Patent Document 2, light can be emitted in all directions by self-luminous illumination, and the existence of the bicycle can be reliably notified to the periphery of the bicycle.

  In addition, as a drive part, it replaces with the above-mentioned transformer and the example which uses a rectifier circuit and an inverter is also described.

Can travel. During this traveling, the EL sheet 53 can be turned on or blinked by selecting lighting or blinking by a switch (not shown) of the driving unit 52 of the EL light emitting device 50.

  Next, the EL light emitting device 50 will be described.

  Here, FIG. 5 is an enlarged view of the drive unit 52 and the front end 53F side of the EL sheet 53 as viewed from the right side when the head tube 11 is vertical. FIG. 6 is an enlarged view of the drive unit 52 viewed from the front side when the head tube 11 is vertical. FIG. 7 is an electric circuit diagram of the EL light emitting device 50. FIG. 8 is an electric circuit diagram of another EL light emitting device 50A.

  As shown in FIGS. 5 to 7, the EL light emitting device 50 includes a hub dynamo 51 as a generator, a drive unit 52, and an EL sheet 53 as an EL light emitter.

  The hub dynamo (generator) 51 is incorporated in the hub 31 of the front wheel 30 as described above. The hub dynamo 51 generates AC power as the front wheel 30 rotates. This AC power is supplied to the drive unit 52.

  As shown in FIG. 7, the drive unit 52 includes a rectifier circuit 52a, an inverter 52b, and a capacitor 52e. The rectifier circuit 52a, the inverter 52b, and the capacitor 52e are disposed on the substrate 52c shown in FIGS. 5 and 6 and covered with a box-shaped (substantially rectangular parallelepiped) cover case 52d. The drive part 52 has waterproofness as a whole.

  The drive unit 52 is formed in a box shape in appearance and is attached to the head tube 11 by a fixture 54. The fixture 54 is configured integrally with the drive unit 52 and tightens the head tube 11 from the outer periphery. The drive unit 52 is attached to the front side 11 a of the head tube 11 and the center in the left-right direction by the attachment 54.

  As a result, as shown in FIG. 8, the drive unit 52 has a small amount of protrusion even when the left end 52 </ b> L and the right end 52 </ b> R protrude substantially the same as the left end 11 </ b> L and the right end 11 </ b> R of the head tube 11. Are arranged as follows.

  The drive unit 52 once rectifies the AC power supplied from the hub dynamo 51 into a direct current by the rectifier circuit 52a, and then uses the capacitor 52e and the inverter 52b to change the frequency, voltage, etc. It converts to electric power. This AC power is supplied to the EL sheet 53.

  The drive unit 52 is provided with a switch (not shown), and by switching, the EL sheet 53 described below can be selected to be turned off, turned on, or blinked.

  An EL sheet 53 as an EL light emitter has a light emitting portion 53a, terminals 53b and 53c, and a waterproof film 53d, and is formed in a sheet shape that can be bent as a whole.

  Among these, the light emitting part 53a can use a general thing. For example, as the light emitting portion 53a, in order from the lower layer side, all are sheet-like protective layers (medium), back electrodes (conductive carbon & silver electrodes), dielectric layers (BeTiO3), light emitter layers (ZnS + Cu), A laminate of a transparent electrode (ITO) and a PET film can be used.

  In addition, although the illustrated light emission part 53a is inorganic EL, organic EL can also be used besides this.

  In the present embodiment, as shown in FIG. 5, the light emitting portion 53a is formed into a bendable sheet shape and an elongated strip shape (line shape). The light emitting portion 53a has a slightly wide front end, and terminals 53b and 53c extend forward from the front end.

  The terminal 53 b has a base end connected to the above-described transparent electrode and a tip end entering the drive unit 52. The terminal 53c has a proximal end connected to the above-described back electrode, and a distal end has entered the drive unit 52 in the same manner as the terminal 53b.

  The waterproof film 53d is for preventing moisture in the air from entering the light emitting portion 53a, and is formed by sandwiching the light emitting portion 53a and the terminals 53b and 53c from both front and back surfaces with a transparent film. A portion of the waterproof film 53d that borders the outer periphery of the light emitting portion 53a in a frame shape looks transparent in appearance.

  This pouch processing is performed on at least a portion of the above-described terminals 53b and 53c, which is connected to the transparent electrode and the back electrode and is located at least outside the driving unit 52 on the base end side. That is, the terminals 53b and 53c have terminal ends protruding from the waterproof film 53d on the end side (the terminals are inside the driving unit 52. These connectors are connected to a connector (not shown). And connected to the inverter 52b of the drive unit 52 via a connector.

  As described above, in the EL sheet 53 as a single unit, the light-emitting portion 53a and the terminals 53b and 53c are prevented by the waterproof film 53d except for the terminal tips. That is, the EL sheet 53 as a single unit does not ensure the waterproofness of the terminal tip.

  However, when viewed as the EL light emitting device 50, the EL sheet 53 is reliably waterproof as the EL sheet 53 because the terminal end of the EL sheet 53 is inserted (inserted) into the waterproof drive unit 52. It can be said that it is secured.

  The above-described EL sheet 53 is attached along the down tube 13. The EL sheet 53 is directly connected to the drive unit 52 on the front end 53F side, passes through the right end 11R of the head tube 11, and is attached to the planar right side surface 13c of the down tube 13 on the rear end 53B side. This attachment can be performed by, for example, a double-sided tape (not shown).

  Since the front end 53F of the EL sheet 53 at the time of attachment is directly connected to the drive unit 52, that is, it is configured integrally with the drive unit 52, the drive unit 52 is attached to the head tube 11 by the attachment 54. Along with the positioning and fixing to the front side 11a, the position of the front end 53F is automatically determined.

  Therefore, at the time of mounting, the EL sheet 53 does not need to support the front end 53A side by hand, and the entire positioning is possible only by positioning the rear end 53B side with respect to the right side surface 13c of the down tube 13. is there. Therefore, the attachment work of the EL sheet 53 becomes easy.

  Instead of attaching the double-sided tape to the EL sheet 53, a magnetic material or an adhesive application part (both not shown) is provided in a part of the EL sheet 53, and the right side surface 13c of the down tube 13 is used by using these parts. You may make it stick to.

  When a magnetic material is used, the EL sheet 53 can be repeatedly attached and detached, and the sticking position can be easily corrected and finely adjusted. Moreover, when an adhesive application part is used, sticking is easy.

  In this embodiment, as shown in FIGS. 1 and 2, the same thing as the EL sheet 53 is also attached to the left side surface 13 d of the down tube 13.

  The example in which the EL sheet 53 is configured integrally with the drive unit 52 has been described above. However, the present invention is not limited to this, and the both are configured separately from each other so that they are connected by wiring. Good. In this case, the degree of freedom with respect to the mounting position of the EL sheet 53 is increased.

  For example, the EL sheet 53 can be attached such that the front end 53F side starts from the vicinity of the front end 13a of the down tube 13 and extends obliquely rearward without being applied to the top tube 11. Further, the EL sheet 53 may be attached not to the down tube 13 but to the upper tube 12 as another tube whose tip side is connected to the head tube 11 as in the down tube 13. Further, the EL sheet 53 may be attached to both the down tube 13 and the upper tube 12.

  In addition, when connecting the drive part 52 and the EL sheet 53 via wiring, since the connection part between the terminal tip of the terminals 53b and 53c of the EL sheet 53 and the wiring is exposed, the connection part of this connection part is exposed. It needs to be waterproof.

  In the above, an example has been described in which the EL sheet 53 is in the form of a sheet and is an elongated strip, and is attached to both the right side surface 13c and the left side surface 13d of the down tube 13. The attachment location for 13 can be arbitrary.

  For example, it may be formed wide so that it extends from the right side surface 13c of the down tube 13 to the left side surface 13d via the upper surface, or may be mounted so as to be wound around the entire circumference of the down tube 13.

  Further, the EL light emitter is not limited to the sheet-like EL sheet 53, and may be a panel shape or a wire shape.

  For example, when the EL light emitter is in the form of a wire, it can be attached to the down tube 13 so as to be spirally wound, and in this case, it can be made to emit light in a spiral.

  If the EL light emitter is attached in close contact with the surface of the down tube 13 in any of a sheet shape, a panel shape, and a wire shape, the protrusion (projection amount) from the surface of the down tube 13 can be suppressed to be small. Therefore, it is difficult to hit the user's leg when driving the bicycle 1 or the user's body when pushing the bicycle.

  In the above description, the drive unit 52 has the rectifier circuit 52a, the inverter 52b, the capacitor 52e, etc., but instead of this, as shown in FIG. 8, an EL light emitting device 50A having a transformer (transformer) 52A is provided. It can also be configured. Here, the drive unit 52 including the rectifier circuit 52a, the inverter 52b, and the capacitor 52e tends to be larger than the drive unit 52 configured by the transformer 52A, but the frequency and voltage of the AC power supplied to the EL sheet 53 are reduced. Fine control is possible.

  The effects of the EL light emitting device 50 of the first embodiment described above and the bicycle 1 including the same will be summarized below.

  In the EL light emitting device 50, since the driving unit 52 is attached to the head tube 11, when the user sits on the saddle 65 and hits the bicycle 1 or gets down from the saddle 65 and walks the bicycle. , Do not touch or hit the user's legs or body.

  In addition, since the EL light emitting device 50 is attached from the head tube 11 to the down tube (another tube) 13 or the head tube 11 to the down tube 13 whose front end 13a side is connected, from the drive unit 52 to the EL sheet 53 The distance between them can be shortened to shorten the wiring between them.

  Furthermore, since the EL sheet 53 is formed in a sheet shape, when attached to the down tube 13, the protrusion (amount of protrusion) from the down tube (another tube) 13 is suppressed, and it is determined by the user. It is possible to prevent the bicycle 1 from hitting the user's leg or body while driving or pushing the bicycle. The same applies to the case where the EL light emitter is in the form of a panel or a wire instead of a sheet.

  -Since the drive part 52 is attached to the front side 11a of the head tube 11, the protrusion in the left-right direction from the frame 10 is further suppressed, and the leg and body of the user are further touched and made difficult to touch. Can do.

  When the EL sheet 53 is provided with a magnetic body that can be attached to and detached from the down tube 13 at least in part, the EL sheet 53 is easily attached to and detached from the down tube 13.

  The EL sheet 53 is easy to attach to the down tube 13 when at least a part thereof is provided with an adhesive application portion that allows the EL sheet 53 to be attached to the down tube 13.

  When the EL sheet 53 is attached to the down tube 13 or both the left side surface 13d and the right side surface 13c of the head tube 11 and the down tube 13, the EL sheet 53 can emit light toward the left side and the right side of the frame 10. And the visibility can be improved accordingly.

  The drive unit 52 includes a switch for switching off, lighting, and blinking of the EL sheet 53, so that the light emission state of the EL sheet 53 can be selected according to the situation.

  Since the generator is a hub dynamo 51 incorporated in the hub 31 of the front wheel 30, the hub dynamo 51 is used as a generator of the EL light emitting device 50 for the bicycle 1 to which the hub dynamo 51 is already mounted. Can be diverted. In this case, the EL light emitting device 50 can be configured by adding the drive unit 52 and the EL sheet 53.

  Instead of the hub dynamo 51, a rim dynamo (not shown) that is attached to the fork 20 and pressed against the front wheel 30 or the rim can be used.

  Since the hub dynamo 51 also serves as a power supply to the headlight 71, it can be used in common by the headlight 71 and the EL light emitting device 50, and the configuration can be simplified accordingly.

  The bicycle 1 can exhibit the above-described effects as the entire bicycle.

  Since the bicycle 1 includes the basket 70 that is attached to the front of the head tube 11 and covers the drive unit 52 from the front, the user or the like can be prevented from touching or hitting the drive unit 52 unnecessarily.

  As described above, the present invention is particularly characterized in the attachment locations of the drive unit 52 and the EL sheet 53 and the connection relationship between the drive unit 52 and the EL sheet 53.

  Accordingly, the individual configurations and functions of the independent generators (for example, the hub dynamo 51), the drive units 52 and 52A, and the EL light emitter (for example, the EL sheet 53) are not particularly limited. Can be used. For example, the generator may be a DC generator.
