Description

The present invention relates to illuminated footwear, and particularly to illuminated footwear that ensures pedestrian walkability in the dark and visibility of pedestrians from a third party walking behind by illuminating the front and back of the footwear.

When walking in a dark environment such as indoors or outdoors, pedestrians are worried that they cannot see their feet. In particular, it is necessary to be careful about falling in places with steps such as stairs. For safe walking, it was required to ensure the brightness of the toes.

As a method of ensuring the brightness of the toes, there is a method of making the footwear itself shine. Specifically, footwear is used to illuminate the area around the toes to ensure safety when walking. From such a background, footwear having a lighting function has been proposed (see Patent Document 1 and Patent Document 2).

According to the footwear of Patent Document 1, a lighting device is installed in the toe, which is the tip portion of the footwear. Further, according to the footwear of Patent Document 2, a mechanism for generating and charging electric power of the lighting device is provided together with the lighting device for illuminating the toes.

The conventional footwear that illuminates the feet remains in a configuration that illuminates the walking direction of the pedestrian, that is, the toes and the circumference of the toes. Assuming a scene of walking in a dark environment, the safety of the pedestrian wearing footwear when walking is ensured. However, when walking in a dark environment, it is safer if the pedestrian's toes can be illuminated to assist the pedestrian's walking and the presence of the pedestrian can be shown to those around the pedestrian. Be done.

The present invention has been made in view of the above points, and by illuminating the footwear having a lighting function other than the toes of the footwear while having a simple structure, not only in front of the pedestrian but also around the pedestrian in a dark environment. We will also provide lighting footwear that can clarify the existence of pedestrians and enhance safety.

That is, the lighting footwear of the embodiment is a lighting footwear having a sole portion and an upper portion, and the lighting portion is housed in the sole portion. The sole portion is formed in the longitudinal direction of the sole portion and the toes of the sole portion are formed. An optical path portion penetrating from the portion to the heel portion, an accommodating portion accommodating the illumination portion, and a part of the light emitted from the illumination portion arranged at a predetermined angle with respect to the optical axis of the light emitted from the illumination portion. A first mirror surface portion that reflects light and a second mirror surface portion that faces the first mirror surface portion and is arranged at an inclination of a predetermined angle to reflect the light reflected by the first mirror surface portion are provided, and the upper portion includes an optical path portion and an accommodating portion. It is characterized by having an inner bottom portion for sealing the portion.

Further, in the sole portion of the lighting footwear, the first mirror surface portion is arranged at an angle of 135 ° with respect to the optical axis of the light emitted from the illumination portion, and the second mirror surface portion is inclined at an angle of 90 ° facing the first mirror surface portion. It may be arranged.

Further, in the sole portion of the illuminating footwear, the optical path portion is a straight-ahead optical path portion in which the light emitted from the illuminating portion travels straight, and the light emitted from the illuminating portion travels straight through the first mirror surface portion and the second mirror surface portion. It may have a reflected light path portion to be provided.

Further, in the sole portion of the lighting footwear, the straight optical path portion and the reflected optical path portion may be arranged so as to be offset in the height direction.

Further, in the sole portion of the illuminating footwear, a reflective member that reflects the light emitted from the illuminating portion may be installed on the inner peripheral portion of the optical path portion.

Further, a joint portion may be provided between the upper surface portion of the sole portion of the lighting footwear and the inner bottom portion of the upper portion, and the sole portion and the upper portion may be united and separated from each other by the joint portion.

Further, in the lighting footwear, the joint portion may be formed by a hook-and-loop fastener or a plate-shaped magnet.

Further, in the lighting footwear, when the sole portion and the upper portion are separated, the lighting portion may be taken out from the accommodating portion.

Further, in the lighting footwear, the lighting unit may be a flashlight capable of generating electricity and charging.

Further, in the lighting footwear, the flashlight may be generated when walking while wearing the lighting footwear.

According to the lighting footwear of the present invention, the lighting footwear is provided with a sole portion and an upper portion, and the lighting portion is housed in the sole portion. The sole portion is formed in the longitudinal direction of the sole portion and the toe portion of the sole portion. An optical path that penetrates from the heel to the heel, an accommodating portion that accommodates the lighting unit, and a part of the light emitted from the lighting unit that is arranged at a predetermined angle with respect to the optical axis of the light emitted from the lighting unit. A first mirror surface portion is provided, and a second mirror surface portion that faces the first mirror surface portion and is inclined at a predetermined angle and reflects the light reflected by the first mirror surface portion. The upper portion includes an optical path portion and an accommodating portion. Since it has an inner bottom that seals the light, it has a simple structure for the footwear that has a lighting function, but by illuminating other than the toes of the footwear, not only in front of the pedestrian but also to those around the pedestrian in a dark environment. The presence of pedestrians can be clarified and safety can be enhanced.

It is an exploded perspective view from the heel part side of the lighting footwear of an embodiment. It is the top view of the sole part and the bottom view of the upper part. (A) A front view of the toe portion of the illuminated footwear and (B) a rear view of the heel portion of the illuminated footwear. It is a schematic perspective view of a reflective member. (A) is a side view of a state in which the heel of the illuminated footwear is raised during walking, and (B) is a side view of a state of landing of the illuminated footwear during walking.

The illuminated footwear of the embodiment illuminates the circumference of the toe portion of a pedestrian walking wearing the illuminated footwear in a dark environment, and also illuminates the circumference of the heel portion, thereby allowing a third party other than the pedestrian. It will be footwear that can make people aware of the existence of pedestrians. That is, the illuminated footwear of the embodiment makes it possible to simultaneously illuminate both ends of the toe and heel of the footwear in the anteroposterior direction. Hereinafter, the lighting footwear of the embodiment will be described in detail with reference to FIG. 1 and the like.

As can be understood from the exploded perspective view of FIG. 1, the lighting footwear 1 of the embodiment includes a sole portion 10 and an upper portion 50. The lighting unit 30 is housed in the sole unit 10. Illuminated footwear 1 disclosed in the figure is in the form of slippers. Hereinafter, the lighting footwear 1 will be described as being in the form of slippers. Of course, the lighting footwear may be various footwear such as sandals, flip-flops, sandals, sneakers, pumps, mules, boots, etc. other than the slippers shown in the figure, and is not limited to the slippers of the embodiment. In the description of the lighting footwear 1 of the embodiment, it is assumed that the sole portion is generally the sole portion 10, and the portion connected to the sole portion 10 and the portion corresponding to the insole and the insole is integrated. Treated as the upper part 50.

The lighting footwear 1 can be separated into a sole portion 10 and an upper portion 50. The instep band 51 is sewn on the inner bottom portion 59 of the upper portion 50. As shown in FIG. 5 below, the pedestrian's foot is inserted between the inner bottom portion 59 and the instep band 51. The insole 59 is called an insole in general shoes and is a plate-shaped member that directly touches the foot. In particular, since the lighting footwear 1 is in the form of slippers, the upper portion 50 is composed of a combination of a plate-shaped inner bottom portion 59 that directly touches the foot and an instep band 51 that touches the instep. Further, a plate-shaped magnet 42 is attached to the lower surface of the inner bottom portion 59 as a joint portion 40. The upper portion 50 has a long elliptical shape including an upper toe portion 27 and an upper heel portion 28. Similarly, the sole portion 10 also has a long elliptical shape including the sole toe portion 25 and the sole heel portion 26.

The sole portion 10 is made of a member made of a material such as polyurethane, which is in contact with the ground and the floor surface and has a high cushioning property to absorb the impact during walking. The sole portion 10 is a plate-shaped member corresponding to the sole (outer sole) of a general shoe. The sole portion 10 of the embodiment is designed to be bulky in the height direction for the convenience of accommodating the lighting portion 30 inside the sole portion 10. Further, a plate-shaped magnet 41 is attached to the upper surface portion 19 of the sole portion 10 as a joint portion 40.

The illumination unit 30 is not particularly limited as long as it is a device capable of emitting light (projecting light). In the embodiment, it is disclosed as a flashlight capable of generating electricity and charging. The lighting unit 30 includes a housing 31, a switch 32, and a light source unit 33. Since the power consumption is low, an LED is used for the light source unit 33.

As can be understood from FIG. 1 and FIG. 2 described later, the sole portion 10 is formed in the longitudinal direction of the sole portion 10 from the toe portion to the heel portion of the sole portion 10 (from the toe portion 25 to the sole heel in the figure). An optical path portion 11 penetrating up to the portion 26) is formed. Then, an accommodating portion 12 accommodating the lighting portion 30 is formed between the optical path portions 11.

The lighting unit 30 is housed in the storage unit 12, and the first mirror surface unit 13 and the second mirror surface unit 14 are housed in the storage unit 12. The first mirror surface portion 13 is arranged so as to be inclined by a predetermined angle with respect to the light source portion 33 of the lighting portion 30 housed in the accommodating portion 12. Then, a part of the light emitted from the light source unit 33 of the illumination unit 30 is reflected by the first mirror surface unit 13. The second mirror surface portion 14 faces the first mirror surface portion 13 and is arranged so as to be inclined at a predetermined angle. The light reflected by the first mirror surface portion 13 is further reflected by the second mirror surface portion 14.

The first mirror surface portion 13 is not large enough to face the entire light source portion 33 of the illumination unit 30, but is approximately half the height. Approximately half of the light emitted from the light source unit 33 of the illumination unit 30 travels straight without being reflected by the first mirror surface unit 13. Therefore, the light that is not reflected by the first mirror surface portion 13 travels straight through the straight optical path portion 15 that is one of the optical path portions 11. Next, the light emitted from the light source unit 33 of the illumination unit 30 and reflected by the first mirror surface portion 13 and the second mirror surface portion 14 travels straight through the reflected optical path portion 16.

The positional relationship between the light emitted from the light source unit 33 of the illumination unit 30 and the first mirror surface portion 13 and the second mirror surface portion 14 will be described with reference to the plan view of the sole portion 10 of FIG. A part of the light emitted from the light source unit 33 of the lighting unit 30 housed in the accommodating unit 12 travels straight through the straight optical path unit 15 as the optical axis L1. Therefore, the illumination unit 30 (the light source unit 33 thereof) and the straight optical path unit 15 are arranged on substantially the same straight line.

The lighting footwear 1 of the embodiment has a configuration in which both the toe portion and the heel portion (sole toe portion 25 and the sole heel portion 26) of the sole portion 10 are illuminated by the light emitted from the lighting portion 30. Therefore, the light traveling straight through the straight optical path portion 15 illuminates the periphery of the sole toe portion 25, and at the same time, the light traveling straight through the reflected optical path portion 16 illuminates the periphery of the sole heel portion 26. Then, it is necessary to branch the light emitted from the light source unit 33 of the illumination unit 30 in the exact opposite direction of forward and reverse.

Therefore, as can be understood from FIG. 2, the first mirror surface portion 13 is arranged at an angle of 135 ° with respect to the optical axis L1 of the light emitted from the light source portion 33 of the illumination unit 30. The second mirror surface portion 14 faces the first mirror surface portion 13 and is arranged at an angle of 90 °. Therefore, the optical axis L2 of the light reflected by the second mirror surface portion 14 travels straight through the reflected optical path portion 16. In this way, both the toe portion and the heel portion of the sole portion 10 are illuminated at the same time.

Of course, the shape of the illuminated footwear and the position of the illuminated footwear are appropriate. Therefore, the illuminated position is not limited to the toe portion and the heel portion, and may be, for example, the outside of the position of the little finger of the foot or the opposite side surface portion of the arch. In this case, the angle of the first mirror surface portion 13 or the second mirror surface portion 14 is changed, and the forming directions of the straight optical path portion 15 and the reflected optical path portion 16 are changed.

In addition, as shown in the bottom view of the upper portion 50 in FIG. 2, a plate-shaped magnet 42 is attached as a joint portion 40 to the lower surface of the inner bottom portion 59 of the upper portion 50. Therefore, the plate-shaped magnet 42 is joined to the plate-shaped magnet 41 of the joining portion 40 provided on the upper surface portion 19 of the sole portion 10. Of course, the poles of the plate-shaped magnets 41 and 42 of the joint 40 are different from each other. Since the plate-shaped magnets of the joint portion 40 are joined to each other in a wide range, sufficient adhesive force can be obtained, and the sole portion 10 does not easily come off from the upper portion 50 when walking while wearing the lighting footwear 1.

As the joint portion 40, instead of the plate-shaped magnets 41 and 42, a hook-and-loop fastener (not shown) can be attached to the upper surface portion 19 of the sole portion 10 and the inner bottom portion 59 of the upper portion 50.

At the same time, the optical path portion 11 (straight-moving optical path portion 15 and the reflected optical path portion 16) and the accommodating portion 12 are sealed through the inner bottom portion 59 of the upper portion 50. Therefore, leakage of light from the upper portion 50 side above the optical path portion 11 is suppressed. Further, the detachment of the lighting unit 30 in the accommodating unit 12 is also avoided.

Further, the sole portion 10 and the upper portion 50 have a structure that can be united and separated from each other by the joint portion 40 (plate-shaped magnets 41 and 42). Therefore, when the sole portion 10 and the upper portion 50 are separated, the lighting portion 30 (flashlight) is taken out from the accommodating portion 12 (see FIG. 1). Since the lighting unit 30 is a flashlight, it can be used independently. Therefore, when it is desired to illuminate a place other than the feet, it can be taken out from the lighting footwear 1 and used, and later returned to the accommodating portion 12 of the lighting footwear 1.

FIG. 3A is a front view of the toe portion of the lighting footwear 1, and FIG. 3B is a rear view of the heel portion of the lighting footwear 1. As can be understood from the front views of FIGS. 1 and 3 (A) above, the straight optical path portion 15 of the optical path portions 11 emits the upper light which is a part of the light emitted from the illumination unit 30. Let it go straight. Therefore, the straight optical path portion 15 is formed at a position close to the upper surface portion 19 of the sole portion 10 or at the upper surface portion 19 itself.

On the other hand, as can be understood from the front views of FIGS. 1 and 3B described above, the reflected light path portion 16 of the optical path portions 11 is a part of the light emitted from the illumination portion 30. Let the lower light go straight. Therefore, the reflected optical path portion 16 is formed at a position deeper than the upper surface portion 19 of the sole portion 10.

In this way, in the sole portion 10, the straight optical path portion 15 and the reflected optical path portion 16 are arranged so as to be offset in the height direction. The straight light path portion 15 and the reflected light path portion 16 are displaced in the height direction, so that the light emitted from the illumination unit 30 can be separated from each other. Therefore, it is not necessary to arrange the lighting unit on both the toe portion and the heel portion of the lighting footwear, and it is possible to avoid an increase in the number of members, an increase in weight, and an increase in manufacturing cost.

Reflective members 20 are installed in the straight optical path portion 15 of FIG. 3 (A) and the reflected optical path portion 16 of FIG. 3 (B). The reflective member 20 has a function of reflecting the light emitted from the light source unit 33 of the illumination unit 30 to the inner peripheral portions of the optical path portion 11 (straight-ahead optical path portion 15 and the reflected optical path portion 16). In the sole portion 10, only the optical path portion 11 (the straight optical path portion 15 and the reflected optical path portion 16) may be formed. However, the amount of light may be attenuated while the light travels straight through the straight light path portion 15 and the reflected light path portion 16. Therefore, the reflective member 20 is installed in order to suppress the attenuation of the amount of light.

FIG. 4 is a schematic perspective view of the reflective member 20. The reflective member 20 is formed of a transparent resin transparent tube material 21 and a metal foil 22. The translucent tube material 21 is suitable as long as it is a transparent resin material, and is, for example, a material such as polypropylene, polyvinyl chloride, polytetrafluoroethylene (PET resin), or polycarbonate. The metal foil 22 is a material such as aluminum foil and tin foil. As shown in the figure, the metal foil 22 is appropriately rolled and inserted through the opening of the translucent tube material 21, and the metal foil 22 adheres to the inner surface of the translucent tube material 21.

Since the inner surface of the translucent tube material 21 of the reflective member 20 is covered with the metallic luster of the metal foil 22, the light traveling straight inside the translucent tube material 21 of the reflective member 20 is reflected by the metal foil 22. Attenuation of the amount of light is suppressed as compared with the case where the reflective member 20 is not installed. In addition, when a pedestrian wears the illuminated footwear 1 and walks, the sole portion 10 during walking is bent and deformed. Therefore, by providing the translucent tube material 21 and the metal foil 22 as the reflective member 20, the reflective member 20 can be deformed according to the bending deformation generated in the sole portion 10, which is convenient.

Instead of installing the reflective member 20 shown in the optical path portion 11, a metal foil is directly attached to the inner wall surface of the straight optical path portion 15 and the reflected optical path portion 16 and the inner bottom portion 59 side (joint portion 40 side) of the upper portion 50. It may be worn. If the reflective member is a metal pipe, it is possible to obtain reflection by the gloss of the inner surface of the metal pipe. However, since the metal pipe does not easily follow the bending deformation that occurs in the sole portion, the metal pipe as a reflective member is not preferable.

Subsequently, the state of walking while wearing the lighting footwear 1 will be described with reference to FIG. FIG. 5 schematically shows the appearance of the lighting footwear 1 and the configuration focusing on the lighting unit 30. Reference numeral F in the figure is the foot of a pedestrian wearing the lighting footwear 1. The lighting unit 30 housed in the housing unit 12 of the lighting footwear 1 shown in FIGS. 1 and 2 has a rectangular shape extending in the length direction and the height direction of the lighting footwear 1, and is vertically located in the height direction thereof. It is a flashlight that irradiates light from the light source unit 33 in the above.

In particular, the lighting unit 30 is a flashlight that can generate and charge electricity. The illumination unit 30 is provided with a switch 32 provided with a push button or a push lever. Inside the housing 31, a gear (bouncing wheel), a spring, a dynamo (generator), a battery, a capacitor, etc., which are driven in conjunction with the pushing operation of the switch 32, are built in (none of them are shown). Therefore, in the lighting unit 30, the internal dynamo generates electricity and the electric power is stored in the battery or the like by repeatedly pushing in and releasing the switch 32, and the LED (not shown) built in the light source unit 33 emits light. It will be possible. Since the lighting unit 30 (flashlight) can generate and charge electricity, it is not necessary to run out of batteries or replace the batteries, and it is easy to secure lighting even in an emergency.

As can be understood from the operation of the switch 32 of the lighting unit 30, the lighting unit 30 is usually able to generate electricity and be charged by repeating holding and releasing the hand. Therefore, in the lighting footwear 1 of the embodiment, the operation of grasping and releasing by the hand of the switch 32 of the lighting unit 30 is diverted to walking, and the lighting unit 30 (flashlight) generates power when walking when the lighting footwear 1 is worn. I am trying to do it.

FIG. 5A is a side view showing a state in which the heel portion of the lighting footwear during walking is raised. In this state, there is almost no load applied from the foot F (heel, sole) of a pedestrian walking with the lighting footwear 1. Further, the sole portion 10 and the upper portion 50 are joined via the joint portion 40. In addition, both the sole portion 10 and the upper portion 50 are formed of an elastic member having a high cushioning property. From this, the switch 32 of the lighting unit 30 (flashlight) housed in the housing unit 12 is not pushed by the upper unit 50, and is in a state of being appropriately lifted as shown in the figure.

On the other hand, FIG. 5B is a side view of the landing state of the illuminated footwear 1 during walking. In this state, all the loads from the feet F (heels, soles) of a pedestrian walking with the illuminated footwear 1 are transmitted from the upper portion 50 to the sole portion 10. Then, the switch 32 of the lighting unit 30 (flashlight) is pushed into the inside of the housing 31 under the pressure from the upper unit 50 directly above. By walking with the lighting footwear 1 on, the states of FIGS. 5A and 5B are repeated, and the lighting unit 30 (flashlight) generates electricity. The lighting unit 30 (flashlight) may further include a changeover switch for switching between power generation and lighting.

As shown in the series of explanations and illustrations, the lighting footwear can illuminate both the toes and heels of the footwear due to the simple structure of the combination of the mirror surface parts, even though the lighting footwear is a single lighting part. Therefore, in a dark environment, it is possible to clarify the existence of the pedestrian not only in front of the pedestrian but also to those around the pedestrian to enhance safety. In addition, a flashlight that can generate and charge electricity is used for the lighting unit, and it is efficient because it can generate electricity and charge when walking while wearing footwear. In addition, the lighting unit can be taken out from the lighting footwear itself, and can be used flexibly according to the situation.
