Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the use of a bicycle in hot weather or in the case of rainfall, without being affected by direct sunlight, heat and ultraviolet rays associated therewith, and rainfall, without holding a parasol or umbrella. By preventing it, the use of the bicycle in the above weather is intended to be safe, convenient, and comfortable, and more specifically, a shade portion that covers the rider's head and a support tool that supports the shade portion, and It relates to the mounting method.

[0002]

2. Description of the Related Art Conventionally, with regard to the use of a bicycle in the hot weather or in the case of rain, the former is often accompanied by using a parasol or umbrella, and wearing a hat or devising a method of wearing clothes. . As for the latter, it is common to wear so-called rain clothing such as synthetic feathers, or use a rain umbrella.

[0003]

Among the conventional techniques described above, raincoats in the case of rainfall are not only heat-and-complexity in appearance or wearing, but also surrounding sounds and visibility are disturbed to some extent. It is rarely worn unless there is a reason such as long-distance running or rain, and in the case of short distances, in most cases, an umbrella is used, or in the case of light rain, it often remains wet. Therefore, it is common to use parasols or umbrellas in either case of hot weather or rain.

[0004] However, it is extremely unstable and sudden to operate a bicycle while holding a parasol in one hand, grasping the handle with one hand, and pedaling the bicycle in a bicycle where balance is strongly required. Braking is difficult and extremely dangerous, and it is by no means recommended. Also, even with a slight wind pressure hitting the umbrella, it is unexpectedly laborious to step on the pedal while holding the handle with one hand while resisting it, and since it is one hand, it does not put much effort in stepping on the pedal, so it is a little slope. But the hard thing is
I often experience it. In addition, depending on the direction of direct sunlight or rain, the umbrella often covers the front, which reduces visibility and is dangerous if items are placed in the basket. Will increase. And although such a risk is well recognized by the person concerned, there is no other simple and effective alternative to this, and the parasol or umbrella is currently used. The present invention has been made to solve the above problems of the conventional technology or method.
The purpose is to protect the rider's head with a support, and to keep it safe, the sunshade has the same effect as using it without holding a parasol or umbrella. It is intended to provide safety, convenience, and comfort for the use of the bicycle in the hot weather or in the rain by making it freely usable.

[0005]

In order to achieve the above object, the present invention provides a pair of left and right awnings for covering a rider's head and a bicycle handlebar as a fulcrum for supporting the awning. , An upper arm, a support rod, and a lower arm and a support member including a mounting band.

[0006] The sunshade part has an area approximately the same as that of a small foldable parasol, is an ellipse that is long in the vertical direction of the bicycle, and has a cap-shaped cover whose outer periphery is curved slightly downward in order to eliminate rainwater at the top. Is. Sunshade structure (Fig. 2)
Is a main transverse bone in the central portion, two auxiliary transverse bones for the front and rear thereof, two outer frame wires constituting an outer frame, two vertical wires constituting a ceiling portion, and each of the above. It consists of two connecting pipes connecting both ends of the wire and a covering cloth. Each of the horizontal bones is a lightweight, bow-shaped, three large and small horizontal bones, with wire passing tubes for passing the outer frame wire at both ends, and two wire passing holes for passing the vertical wires on the left and right of the top. , 2 outer frame wires through the wire passing tube, and 2 vertical wires through the wire passing hole, both ends of which are inserted into two substantially comb-shaped connecting tubes and temporarily fixed to form a shade frame. It is a thing. This has the same shape as the framework of the sunshade, a rubber ring is attached to the folded part on the back side to give tension, and a covering cloth made of waterproof thin cloth is covered to form the sunshade. The temporarily fixed sunshade frame is shaped and stabilized by the tension of the rubber ring on the back side of the cover cloth, and is shaped and stabilized. For this reason, it is desirable that both ends of the framework be curved slightly downward at the time when the shade framework is constructed. Further, the wire threading tubes at both ends of each transverse bone may be a simple hole or a groove shape that is fitted by being strongly pressed as long as the transverse bone has strength. At both ends of the main transverse bone, holding plates for holding the shade portion are provided by being inserted into a groove of an upper arm described later.

[0007] The holding plate is a plate having a corner of the upper arm inserted into the groove of 150 mm in width, 20 mm in length, and 3 mm in thickness, and has no corners. Since it is necessary to prevent the bicycle from falling over easily by detaching the part, the holding force is sufficient to withstand the effects of wind pressure and rainfall during riding, and the structure is lightly inserted from above. In addition, the awning section will not be injured even if it comes off by a gust and hits a passerby.
It has a shape with no point. For this reason, it is also a good idea to tie the rear part of the sunshade and the vicinity of the bicycle saddle with a strong thread.

The shape of the shade portion may be circular. Further, in order to reduce the influence of gusts and the like as much as possible, it is desirable to make the slope as flat as possible so that rainwater at the top can be removed, and to make it as flat as possible.

The material of the shade portion may be polystyrene foam, waterproof cardboard, or molded plastic.

The structure of the shade portion may be a turtle shell-shaped umbrella structure without a handle, which is convenient for attachment and detachment and carrying. In this case, the pillar in the center of the shade (Fig. 10)
Is a cylindrical column with a diameter of 12 mm and a length of about 70 mm and a closed lower end, which is made of rubber and has a kokeshi-shaped fixing rubber inserted at the upper end and fixed with an adhesive. When the pillar is pushed to open the shade, when the kokeshi-shaped head of the fixed rubber at the top of the pillar penetrates the ring-shaped ceiling hole,
Elasticity of rubber spreads outwards to fix and prevent rainwater from entering. In addition, there is a cylindrical holding rod with a closed lower end having a diameter of 5 mm and a length of about 20 mm at the tips of two adjacent umbrella bones on both the left and right sides (Fig. 9). Holds the awning by inserting. At the tip of the umbrella bone, a U-shaped bone is crushed, and a push pin-shaped pin having a flat head and a spherical shape is inserted to eliminate the tip. The holding rod may be fixed, but it is desirable that the holding rod is allowed to move freely in the direction parallel to the umbrella bone in case the awning part comes off due to a gust and hits a passerby. The holding plate insertion groove of the upper arm, which will be described later, needs to have a structure suitable for inserting a holding rod.

[0011] It is desirable that the weight of the sunshade part be equal to or smaller than that of a small folding parasol so as not to hinder the running of the bicycle.

The upper arm is a substantially pistol-shaped support tool (FIG. 4) that supports the awning portion and that can be easily detached from the awning portion when an external force such as a gust is received to prevent danger. Since the back part lightly supports the holding plate of the sunshade part, the holding plate insertion groove has a shallow groove shape, and a cup-shaped support rod tip insertion hole is attached to the lower end. Insert the holding plate of the sunshade into the holding plate insertion groove,
The tip of the support rod, which will be described later, is inserted into the support rod tip insertion hole to support it. The mounting angle of the support rod tip insertion hole is set so that the support rod bends backward as the support rod tip portion bends.

The support rod is a metallic two-step rod, such as a rod antenna of a portable radio, which can be expanded and contracted, in order to support the upper arm and adjust the mounting height of the shade portion, and the tip end portion thereof. , It has a curved shape in a V shape, and at the tip and the lower end, as a cushioning material for inserting into the insertion holes of the upper arm and the lower arm described later,
It has a rubber cushion that is covered with a cylindrical rubber and fixed with an adhesive. The lower end is provided with an air hole in order to eliminate air resistance when the rod expands and contracts. The tip of the support rod is inserted into the support rod tip insertion hole of the upper arm, and the lower end is inserted into the support rod lower end insertion hole of the lower arm to support. The support rod bends backward due to the curvature of the tip, the mounting angle of the support rod tip insertion hole of the upper arm, the weight of the shade and the upper arm, and the wind pressure associated with traveling. , The contact resistance of the upper and lower rod joints becomes large, and it does not slide down even if there is some impact. In addition, it absorbs the shock of traveling and supports the sunshade in a wobbling state. For this reason, it is desirable to use a rod that has the largest resistance when expanded and contracted.

The mounting band is an inverted U-shaped band with an open lower part for mounting the lower arm at an appropriate position on the handlebar of the bicycle, and has bolt holes through which tightening bolts are provided at both ends of the lower part. It is one that is paired with the lower arm. The lower arm (FIG. 6 (b)) is for supporting the support rod and for adjusting the vertical angle of the shade portion, and is a support tool having a central portion curved in a V shape, One end has a cup-shaped support rod lower end insertion hole, and the other end is a tightening bolt. Using the mounting band, tighten the accessory thumbscrew to secure it in place,
Insert the lower end of the support rod into the support rod lower end insertion hole to support it. Also, for the stopper at one end of the tightening bolt,
There is a slit-like notch to prevent the attached lower arm from wobbling left and right.

It is convenient for putting on and taking off and carrying it that all the supporting tools are of the insertion type, and in case of receiving a gust of wind,
This is because it is easy for any of the insertion parts to come off and the awning part to come off.

The upper arm, the support rod, and the lower arm are not divided, but are integrally structured as an integrated support, or a further simplified one thereof, for example, the tip of a long and slender metal pipe is used as a shade portion. Insert it in the provided insertion hole,
The lower end is passed through a ring-shaped wire rope attached to the tip of a rod-shaped tightening bolt, a suitable washer is attached to the mounting band, and the height is adjusted while tightening and fixing with a thumbscrew. You can also use ingredients.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Because of the configuration as described above, it is possible to prevent the effects of direct sunlight, heat and ultraviolet rays associated therewith, and rainfall without holding a parasol or umbrella. , It becomes extremely safe because both hands are free. Also, compared to using parasols or umbrellas,
It is less affected by the wind, and is safe because the awning part can be easily detached to prevent danger even when an external force such as a gust of wind is received.

[0018]

An embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing a state where a sunshade is mounted on a bicycle.
As shown in the figure, the shade portion 1 is a cap-shaped cover in which an oval dish is laid down, and a pair of left and right upper arms 14, support rods 17, and lower arms 23 and a mounting band 21 are used with a handle bar 37 as a fulcrum. Supported. Shade section 1
The mounting height is determined by the support rod 17, and the vertical angle is determined by the mounting angle of the lower arm 23. Since the support rod 17 bends backward as shown in the figure, the contact resistance between the upper and lower rod joints becomes large, and the support rod 17 does not slide down.

5 is a wire threaded pipe 8 made of the same material by molding aluminum or plastic with grooved U-shaped grooves at both ends.
Is a bow-shaped horizontal bone provided with two wire through holes 9 through which the vertical wires 7 are passed on the left and right sides of the top, which are fixed by caulking or an adhesive. Two outer frame wires 6 are passed through the wire passing pipes 8 at both ends of each transverse bone 3, 4, 5 and two vertical wires 7 are passed through the wire passing holes 9 on the left and right of the top.
Both ends of each wire 6, 7 are inserted into two substantially comb-shaped connecting pipes 11 made of aluminum or plastic and temporarily fixed. Outer frame wire 6 and vertical wire 7
Is a metal having a rigidity that allows the shape to be maintained during use. Further, holding plates 10 made of aluminum or plastic are attached to both ends of the main transverse frame 3. FIG. 3 shows the awning framework 2 which is temporarily fixed.
FIG. 3 is a rear perspective view of the shade portion 1 which is shaped by covering the cover cloth 12 completely. Due to the tension of the rubber ring 13 on the back surface of the cover cloth 12, the cover cloth 12 is in a taut state, and the shade portion 1 is shaped. Therefore, the shade frame 2 may have some looseness. When the tension of the rubber ring 13 is insufficient, the back surface of the cover cloth 12 may be made large, the diameter of the rubber ring 13 may be made small, and a hole may be provided in the cloth that contacts the holding plate 10. Then, the holding plates 10 at both ends of the main transverse frame 3 are inserted into the holding plate insertion grooves 15 of the upper arm 14 to hold the shade portion 1.

FIG. 4 is a perspective view of the upper arm 14.
The upper arm 14 is a substantially pistol-shaped support in which two thin aluminum or plastic plates each having a concave surface open on one side are attached to each other so that the concave surfaces are fitted to each other, and caulking or an adhesive is used. Is a holding plate 10 of the shade unit 1.
Is a holding plate insertion groove 15 into which the
Support rod tip insertion hole 1 made of aluminum or plastic
6 is attached. In the holding plate insertion groove 15, the holding plate 10 of the shade portion 1 and the support rod tip insertion hole 1
6, the portion of the rubber cushion 18 at the tip of the support rod 17 is inserted and supported. Both side surfaces of the upper arm 14 have the same shape.

FIG. 5 is a perspective view of the support rod 17.
The support rod 17 is a two-stage expandable metal rod having a curved V-shaped tip, and the rubber cushions 18, 19 at the tip and the bottom are respectively inserted into the support rod tip insertion holes of the upper arm 14. 16, and the lower arm 23 is supported by being inserted into the support rod lower end insertion hole 24. An air hole 20 is provided at the lower end.

FIG. 6A shows a metal mounting band 21 for mounting the lower arm 23 to the handlebar 37.
6B is a perspective view of the lower arm 23. FIG. The lower arm 23 is a metal support that is integrally formed with a tightening bolt 26 and has a central portion curved in a V shape and a support rod lower end insertion hole 24 at one end.
It is a combination with 1. The tightening bolt 26 is passed through the bolt hole 22 of the mounting band 21 and is tightened and fixed by the thumbscrew 25. The rubber cushion 19 at the lower end of the support rod 17 is inserted into the support rod lower end insertion hole 24 to be supported. Further, the stopper 27 has slit-like cuts and slits 28 on the contact surface with the mounting band 21 to prevent the lower arm 23 from wobbling. Slit 2
8 may be omitted if the lower arm 23 can be firmly fixed.

Since all of them are of the insertion type except the attachment of the lower arm 23, the holding plate 10 of the upper arm 14 is pulled out to prevent the awning part 1 from being particularly dangerous against gust from the left and right.
However, when the gust comes from another direction, one of the insertion portions comes off, and the shade portion 1 easily comes off.
Therefore, a relatively gentle supporting force is desirable other than the attachment of the lower arm 23.

FIG. 7 and FIG. 8 are a side view and a front view showing a state where the awning is attached to the bicycle.

FIG. 9 is a perspective view of the shade portion 29 of the umbrella structure. As shown in the figure, it is a shaded portion having a tortoise shell shape, and the holding rod 30 is a cylindrical rod made of metal and having a closed lower end.

By the supporting bones 35 interlocking with the support columns 32, the shade portion 29
When the opening is opened, when the mosquito-shaped head of the fixing rubber 31 penetrates the ring-shaped ceiling hole 33, the fixing rubber 31 is elastically spread to the outside and fixed, and rainwater is prevented from entering. The holding rod 30 is
The awning portion 29 is freely moved in a direction parallel to the umbrella frame 34 in order to prevent a risk when the awning portion 29 is separated by a gust and hits a passerby. Further, a push pin-shaped pin 36 having a flat head and a spherical shape is inserted at the tip of the cap bone 34 to eliminate the pointed end. In this case, the holding plate insertion groove 15 of the upper arm 14 needs to have a structure suitable for inserting the holding rod 30. Although an integrated support tool having a structure in which the upper arm 14, the support rod 17, and the lower arm 23 are integrated, or a simplified support tool that is a simplification thereof, is not shown, but in the case where the insertion part is the former, The holding plate insertion groove 15 has one position, and the latter case has the same position as that of the insertion hole provided in the shade portion.
