Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-emitting umbrella that emits light to a part (a sword or a sword and a grip) constituting an umbrella so that the umbrella can be watched appropriately.

2. Description of the Related Art Heretofore, there have been many proposals for emitting light at an umbrella portion, and among them, there have been proposed some devices which emit light by operating a grip part of an umbrella. With this configuration, light is emitted during rain at night so that the human eye can be watched and attention is drawn. However, as a result of actual trial production and trial experiments, the inventor has found that the conventional configuration has the following problems in terms of production or safety in actual implementation. 1) A device in which a light bulb is provided in a stone butt to emit light This configuration is disclosed in Japanese Utility Model Laid-Open No. 62-200925, Japanese Utility Model Laid-Open No. 63-13015,
Publications have been proposed. In both cases, a light bulb is provided in a stone foot, and the stone foot is illuminated by an on / off operation of an open / close switch provided on a grip (or a hand part). However, in this configuration, the sword and grip (or hand)
, At least one lead wire must be wired and connected in the center shaft. This process is a production process
Since the lead wires are wired inside the center shaft and then connected, production is not possible unless the lead wires of the light bulb socket and the power supply unit are connected by soldering or the like or connected by a connector or the like during assembly. For this reason, in the manufacturing process, the cost of the manufacturing process of connecting the lead wire of the light bulb socket and then connecting to the power supply unit or connecting with a connector or the like, and the cost of parts are considerably increased. Further, in actual use, the umbrella is very rough and easily handled, and it is easy to cause poor contact or disconnection of a portion connected by a connection or a connector or the like. In this case, lighting becomes impossible. In addition, the bulb provided at the tip of the umbrella, which is most prone to impact, has a problem in actual use, which is liable to be damaged by impact. 2) An optical transmission line such as an optical fiber is provided in the center axis, light emitted from a bulb provided in the handle is made to enter the optical transmission line and transmitted, and the light illuminates a stone end provided at the tip of the center axis. As a configuration, Japanese Utility Model Laid-Open No. 57-40315 and Japanese Utility Model Laid-Open No. 3-45714 have been proposed. Even with this configuration, a step of providing an optical transmission line into the center axis is included in the conventional umbrella production process, which further increases the manufacturing cost and component cost. Also, as a fatal problem, when actually implemented with that configuration, there is a limit to the amount of light emitted by the battery, and let the maximum amount of light pass through an optical transmission line with a diameter of several mm. As
Since only the amount of light that is proportional to the diameter can be incident and transmitted, the entire stone shovel is hardly illuminated and is hardly seen, which is not practical. 3) The center shaft is formed of a transparent resin, and the light emitted from the bulb provided on the handle is incident on and transmitted through the center shaft, and the light shines on the stone end provided at the tip of the center shaft. No. 133719 has been proposed. In this configuration, since the diameter of the central shaft formed of a transparent resin body for transmitting light can be 10 mm or more (7 mm has no strength), light enters the optical transmission line such as the optical fiber. Rather than letting it pass, it can make the stone shine brighter. However, even in this configuration, the transmittance of light transmitted through the transparent resin is at most about 90%, no matter how transparent, and 90% of the light travels straight through the resin and reaches directly. 90
%, During which 10% of the straight light is attenuated. Also, since the light emitted from the light bulb is actually diffused, there are light that attenuates while repeating reflection on the surface inside the resin body, and light that is transmitted from the inner surface to the outside when reflected. The light spar butt will not shine.
For this reason, in order to brightly illuminate the stone shovel, the diameter of the central shaft must be increased, but if the general umbrella is set to 14φ, the whole umbrella becomes extremely heavy. Also, as a manufacturing problem, if the center shaft is formed of a resin body, it is structurally very difficult to provide a metal fitting for holding the lowering pot when the umbrella is opened and closed. However, there is also a problem that the umbrella is limited to an umbrella called a no-hajiki which does not use a metal fitting for holding the lower wheel when the umbrella is opened and closed.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention is to be solved by the present inventors based on the results of actual trial and prototype experiments. The purpose of the present invention is to eliminate the wiring and connection of the lead wires in the center shaft, or the connection by the connector, etc., so that the configuration can be performed with the lowest manufacturing cost, and to reduce the amount of light emitted from the bulb provided in the grip. The most efficient way to transmit the light to the butt is to make the shine brightest.

According to the present invention, a light emitting source is provided in a grip, and the light is transmitted from the most efficient light transmitting method in order to make the stone shine bright. As a method of transmitting light emitted from A to B when two points A and B exist between the two points, one of the methods is to transmit light into a transparent resin body (optical transmission body) having a high light transmittance. There is a method of transmitting data by using a conventional method, and the configuration is proposed in a known invention. However, the present invention utilizes, as a completely different method, a method of transmitting and transmitting light by entering and transmitting light into a hollow cylindrical body.
By transmitting light into the center axis and transmitting light emitted from the light source inside the grip to the stone stake most efficiently, the stone sword made of a translucent member can be made to shine the brightest. It is.

FIG. 1B is a front cross-sectional view of the entirety with the grip 5 opened.
It is a longitudinal cross-sectional view of a part. In FIG. 1A, the center shaft 4 is formed of a hollow aluminum material having an outer diameter of 14Φ and a wall thickness of about 1 mm, and a stone foot 2A formed of a translucent member is fixedly provided at the upper end thereof. Here, a transparent or translucent plastic material can be adopted as the translucent member, and acrylic resin, polyester, polycarbonate, polymethylpentene,
Polystyrene, cellulose acetate, polypropylene, cellulose butyrate, AS resin, transparent ABS resin, polybutadiene, polyurethane, epoxy resin, polyamide, phenolic resin, unsaturated polyester, silicone resin, ionomer, polysulfone, polybutene, rigid vinyl chloride resin, polyethylene, It can be made of EVA resin, plastic such as polypropylene, or tempered glass. A grip 5 is screwed into the lower end of the center shaft 4. The grip 5 includes a lamp 7 composed of a miniature bulb, two rechargeable AA batteries 8 connected in series, and an open / close switch 5 e. The circuit is provided in series. The lamp 7 is turned on / off by opening and closing the open / close switch 5e. Here, the configuration of the grip 5 will be described in more detail with reference to FIG. The grip 5 is formed of a cylindrical resin, the upper part of the inner wall surface is threaded, and the concentric ring-shaped step part 5b protrudes from the lower part. Then, the threaded portion above the step 5b and the portion threaded on the lower surface of the center shaft 4 are screwed together and fixed. A metal socket terminal 5c to which the lamp 7 is screwed and connected is fitted into the inner peripheral surface of the step portion 5b,
The socket terminal 5c is brought into contact with the positive electrode connection electrode 5d. Then, both the positive electrode connection electrode 5d and the negative electrode connection electrode 5d connected to the negative electrode of the lower battery 8 are molded and buried in the resin as shown in the figure. Both ends of the two electrodes are exposed, and an open / close switch unit 5e is provided for opening and closing the two electrodes by operating them toward and away from each other. The opening / closing switch section 5e can be configured by a button opening / closing operation for pressing or releasing one flexible connection electrode 5d against the other connection electrode 5d. Next, below the step 5b, a gap is formed in which two single 5 dry batteries 8 can be loosely fitted in series.
An opening at the lower end is provided with a cap 5a that is screwed in and closed. With two dry batteries 8 inserted in series, the positive electrode of the upper dry battery 8 directly contacts the terminal of the lamp 7. The spiral electrode provided on the upper surface of the cap 5a and the negative-electrode-side connection electrode 5d come into contact with each other when the cap 5a is screwed in and the lid is closed, thereby forming a circuit connection.
With such a configuration, the lamp 7 can be replaced and replaced when the center shaft 4 is released from the grip 5. In addition, since there is no lead wire or connection in this configuration, the production is very simple. In production, only the grip 5 can be manufactured separately and assembled by screwing to the center shaft 4. The production cost at the time can also be very low. The actual use in this embodiment is based on the
e by pressing the thumb with the thumb, the contact electrode 5
d and 5d contact each other to close the circuit, and the lamp 7 is turned on. The light of the lamp 7 is incident on the central shaft 4, and the light reaches the stone 2 </ b> A formed of the translucent member while repeating irregular reflection and transmission in the central shaft 4, and makes the entire stone 2 </ b> A bright <light. Can be. Here, the light emitted from the lamp 7 and transmitted through the central shaft 4 does not leak to the outside, so that the light can be efficiently transmitted to the stone foot 2A. However, the inner surface of the central shaft 4 is plated or mirror-finished. Light can be transmitted more efficiently. The light emitted from the stone butt 2A is light that has been repeatedly reflected and diffused in the translucent member, and is not light directly looking at the light source, so that the light does not dazzle the eyes, especially in darkness. It can be seen with gentle soft light, does not have any dazzling adverse effects and does not tire of looking. In this configuration, since the metal fitting for holding the upper and lower wheels is attached perpendicularly to the traveling direction of the light in the center shaft 4, transmitted light is hardly blocked. In the opening / closing operation, if the opening / closing switch section 5e is periodically pressed with the thumb, the lamp 7 blinks, and the stone foot 2A also blinks and shines, so that the surroundings can be more closely watched. Note that the way of inserting the battery 8 is not limited to the opening at the lower end of the grip 5 but also the grip 5.
A lid that can be opened and closed in a sliding manner or a lid that can be opened and closed in a door manner may be provided on the side surface of the device. In addition, center axis 4
The method of fixing the handle 5 to the grip 5 is not limited to screwing as in the present embodiment, but can be fixed by fitting or other methods. Central axis 4
The same applies to the stone butt 2A. FIG. 2 shows a second embodiment of the present invention. 2A is a front cross-sectional view of the entire umbrella 1 opened, and FIG. 2B is a vertical cross-sectional view of a grip 5 portion. As in the first embodiment, the ram 2 is formed of a ram 2A formed of a translucent member, and the grip 5 is formed of a grip 5A formed of a housing of the translucent member. With this configuration, the light emitted from the lamp 7 is
From the head of the lamp 7 into the central shaft 4 and from the side of the lamp 7 into the grip 5A and transmitted therethrough. The light from the side of the lamp 7 causes the side of the grip 5A to emit light brightly. With this configuration, the ram 2A and the grip 5A can be simultaneously illuminated. The effect of the configuration of this embodiment is that
Light can be emitted as if a light source were provided in each of the grips 5A, and there is an effect that one light source emits light as if there were two light sources. This effect can be achieved, for example, by using a lead wire to send current to emit light from a light bulb placed on a stone pole.
Is necessary, and there is an effect that can be achieved with only one light source (bulb). The portion of the housing of the grip 5 formed by the translucent member may be the entire housing or only the side portion of the lamp 7. FIG. 3 shows an embodiment in which light emitted from the lamp 7 is not diffused as much as possible but is incident on the center shaft 4. In one embodiment, the upper periphery of the socket terminal 5c supporting the lamp 7 is constituted by a parabolic reflector 5f. With this configuration, the light emitted from the lamp 7 in the lateral direction is reflected by the reflecting mirror 5f, and the entire optical path of the light goes straight into the central shaft 4 and enters. As a result, the light emitted from the lamp 7 is focused as much as possible,
And can be transmitted through. As another configuration that can be implemented, a lens may be provided in front of the lamp 7 or on the lamp 7 itself to condense the radiated light in a narrow directivity. With such a configuration, light emitted from the lamp 7 can be efficiently incident on the center shaft 4 and transmitted. In addition, as the configuration of the stone foot 2A made of a translucent member, bubbles such as air bubbles scattered in the stone foot 2A formed of a transparent body, powder or granules that shine brilliantly, and color patterns are used. They may be mixed, and the surface of the stone foot 2A may be formed in an uneven shape. With this configuration, the light emitted from the stone foot 2A shines variously and can be made to shine very beautifully. FIG. 4 shows a fourth embodiment of the present invention. As in the previous embodiment, the grip 5 is composed of a grip 5A made of a housing made of a light-transmitting member, and the lamp 7 is used as a light source with a red L.
The limiting resistor R is connected in series in the lighting circuit. The light emitted from the side by making this configuration a red LED enters the inner surface of the adjacent grip 5A and repeats reflection and transmission / diffusion in the housing as in the previous embodiment, thereby causing the entire housing to glow red. be able to. FIG. 5 shows an embodiment of the present invention applied to a folding umbrella. As a configuration of the folding umbrella 1, the support 4 is an upper support 4-
1 and the lower support 4-2 fit each other and slide up and down. According to the configuration of the present invention, even when the upper support 4-1 is slid and housed in the lower support 4-2, the light transmitted up to the stone foot 2A is not blocked at all. The configuration of the present invention can be applied to a folding umbrella.
FIG. 6 shows a sixth embodiment of the present invention. In this configuration, a hollow space is provided below the step portion 5b of the grip 5, a vertical groove 5g is formed on the side surface of the grip 5 vertically upward from the lower end, and a cap 5a screwed into a lower opening of the grip 5 is provided. . The penlight 10 separate from the umbrella 1 can be inserted and removed so as to be loosely fitted in the hollow space provided in the handle 5. When storing the penlight 10 in the handle 5, the operation switch portion 10a is inserted into the vertical groove 5g by sliding and fitting. In this state, grip 5 with cap 5a.
Is screwed into the opening, and the lid is closed, so that the penlight 10 is kept in the grip 5 and the operation switch unit 10a
Can be opened and closed, and in this state, an operation of turning on / off the lamp 7 is possible. Here, the penlight 10 may be of a portable size, including a so-called flashlight, and may have any shape that can be fitted in the hollow space. Further, the operation switch unit 10a of the penlight 10 may be provided on the bottom surface, and an opening for operating the cap 5a when the cap 5a is mounted may be provided at the center of the cap 5a. Further, the cap 5a may not be specially provided, and the housing of the penlight 10 may be fixed in the hollow space by fitting, screwing or other methods. The configuration of the sixth embodiment has the following advantages in production. The production of both a general umbrella that does not aim to emit light and a umbrella that emits light can be produced with a mutually common design structure. That is, by making the grip 5 have a hollow structure as in the present embodiment, an ordinary umbrella that does not aim to emit light is also manufactured in this configuration. By wearing
A luminous umbrella can be made as appropriate. In this way, both production of general umbrellas and luminous umbrellas can be simplified according to demand, and by using a common design structure for production, components and production processes can be shared, minimizing production costs. it can. In addition, a separate penlight 10 can also be configured to be fitted by adopting a ready-made product as it is, and with such a configuration, it is possible to further reduce production cost and product cost. Furthermore, in actual use, it is possible to take out the penlight 10 from the inside of the grip 5 as needed and illuminate the penlight 10 freely with the right hand while holding the grip 5 of the umbrella 1 with the left hand, for example. If this is a known example, if a flashlight is fixed to the grip,
Even if you try to change the direction freely, it is an operation while holding an umbrella, and it is actually difficult to illuminate that direction freely. FIG. 7 shows a seventh embodiment of the present invention. This configuration provides a hollow space in the grip 5 as in the previous embodiment,
3 shows a structure of a spiral connector 15 that can be inserted into and removed from the space. As shown, the structure of the spiral connector 15 is
The base portion of the lamp 7 is spirally wound with a steel wire of a spiral wire 12 and fixed by winding.
The lower part of 2 forms a spiral inner space having an inner diameter of 12Φ, and two single-size batteries 8 are inserted in series in the inner space, and a spiral conductive wire is brought into contact with the negative electrode of the lower-stage dry battery 8. The end of 12 is scalloped. The positive electrode portion of the upper dry battery 8 and the terminal portion of the lamp 7 are configured so as to have a slight gap. When the spiral connector 15 thus configured is inserted into the hollow space in the grip 5 and the cap 5a is screwed and fitted in this state, the cog-shaped portion of the spiral conductive wire 12 is pressed. An opening / closing operation unit 5h that is closed to form a closed circuit is provided on the cap 5a. When the opening / closing operation section 5h is pressed inward in this configuration, the positive electrode portion of the upper dry battery 8 and the terminal portion of the lamp 7 come into contact with each other to form a closed circuit, and the lamp 7 is turned on.
When the pressing force is removed, the positive electrode portion of the upper dry battery 8 and the terminal portion of the lamp 7 are separated again by the restoring force of the spiral conductive wire 12, and the lamp 7 is turned off. With such a configuration of the spiral connection body 15, it is possible to implement it very inexpensively. As the structure of the opening / closing operation portion 5h, the width of the threaded portion of the cap 5a is increased, and the opening portion is screwed deeper by the width, so that the positive electrode portion of the upper dry battery 8 and the terminal portion of the lamp 7 come into contact. It is also possible to configure by a method such as this or other methods. In the configuration of the present invention, the light-transmitting member may be formed of a transparent body, may be formed of a turbid body such as smoke or milky white or each color body, or may have a light-transmitting property containing a fluorescent agent. You may comprise with a fluorescent member. By doing so, it is possible to illuminate fluorescent colors such as red, green, yellow, blue, and pink. The central shaft 4 can be made of iron or aluminum, and the larger the diameter, the more light can be transmitted. Therefore, a general-purpose 14φ is more suitable than a general-purpose 7φ, 10φ. Further, the lamp 7 may be constituted by a light bulb or an LED (light emitting diode). Here, in the case of a light bulb, a light bulb with a lens having a narrow directivity is preferable because it can collect light. In the case of an LED, a red LED having a high luminance is preferable because light is hardly attenuated. The amount of light can be appropriately varied and set by the value of the resistance element R connected in series. FIG. 8 shows that the lamp 7 made of a light bulb is turned on /
Fig. 3 shows an example of a circuit for blinking. By connecting the lighting / flashing circuit 11 to the circuit, the lighting / flashing can be switched to lighting or flashing according to the situation at the place, and the flashing can be performed when the visual appeal is most desired. FIG. 9 shows an example of a circuit for turning on / off the lamp 7 composed of an LED. Using two-color LED of red and green, this circuit can continuously emit red or green, and alternately light red and green to emit light, or to blink only red or green only. it can.

Since the present invention has the above-described configuration, the following effects can be obtained. Since the configuration is such that there is no connection by a lead wire or a connection or a connector at all, it is possible to emit light from the umbrella's stone foot in a configuration that requires the least component cost and production cost. In addition, light emitted from the light source provided in the grip,
The most efficient transmission to the stiletto with the least loss allows the stiletto to shine brightest. In addition, since the light is light that is not directly viewed by the light source, the light emitting portion can be viewed with soft and gentle light, and does not adversely affect the viewer (shading, fatigue, tension, etc.). In addition, since the penlight and the spiral connector can be inserted and removed separately, the production cost can be extremely reduced, and the penlight can be freely illuminated by holding the penlight with the right hand at an appropriate time.
