Japanese Unexamined Patent Publication No. 2008-270078

The general balloon 6 shown in FIGS. 1 and 2 is configured to be inflated by the air pressure of the outside air taken in from the outside. Therefore, an electric blower 7 such as a sirocco fan with a motor is installed adjacent to the light source device 4.

However, as a result of the need for the electric blower 7 for inflating the balloon 6 and the wiring for supplying electric power to the electric blower 7, there is a problem of increasing the cost as a whole, and the weight is heavy, so that the handling is easy. There is a problem that it is not.

Further, since the balloon 6 is inflated by air pressure, it is necessary to prevent air from leaking from the inside of the balloon to the outside. In this case, the ambient temperature around the light source device 4 rises and becomes high. There's a problem.

In order to prevent the air inside from leaking to the outside, the balloon 6 has a structure that cannot be removed, and the upper disk and the lower one that are always arranged above and below the light source device 4 (and the electric blower 7). It is attached to the disk.

However, the non-removable balloon 6 keeps the balloon 6 fixed to the light source device 4 (and the electric blower 7) in which the pole 3 is contracted and lowered when the unused floodlight is stored. Since it has to be folded, the folding work is complicated.

An object of the present invention is to provide a balloon-type floodlight that solves the above problems.

Therefore, what the present invention has constructed as a means is a balloon-type floodlight configured by incorporating a light source device inside the balloon, and the balloon is located at a portion having the maximum diameter of the balloon formed of a sheet material. An elastic wire is provided around the circumference, and the balloon shape is maintained in the radial direction by the elastic wire, and the balloon is detachably attached to the light source device.

In a preferred embodiment, the upper and lower discs are provided above and below the light source device, respectively, and the balloon locks the upper inward flange portion formed in the upper opening to the peripheral edge portion of the upper disc. The shape of the balloon is maintained in the vertical direction by locking the lower inward flange portion formed in the lower opening to the peripheral edge of the lower disk, and the lower inward flange portion holds the lower opening. An opening / closing means that can be expanded / contracted is provided, and the lower opening is opened to allow the lower disk to pass through, and the lower opening is contracted to be locked to the lower surface of the peripheral edge of the lower disk. It is configured as follows.

Preferably, the opening / closing means of the lower inward flange portion is composed of a slit for dividing the flange portion and split hem portions on both sides of the slit, and the lower opening is opened by opening the split hem portions in a direction away from each other. It is configured to contract the lower opening by opening and expanding the portions and closing each other, and is provided with a fastener that detachably fixes the split hem portion in a state of being closed to each other.

The elastic wire forms a circular ring in which both ends are connected and fixed to each other. With the balloon removed from the light source device, the circular ring is elastically deformed so that the balloon and the elastic wire can be folded together. It is preferably configured.

According to the present invention, since the balloon 6 capable of retaining the shape of the balloon via the elastic wire 8 without being inflated by air is provided, it is not necessary to provide an electric blower 7 as in the prior art, and moreover. The balloon 6 has an advantage that it can be easily and compactly folded by elastically deforming the elastic wire rod 8 in a state of being removed from the light source device 4.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The balloon-type light source of the present invention has the same basic configuration as the balloon-type light source according to the prior art described with reference to FIG. 1, and the generator 2 is mounted on the wheeled carrier 1. A telescopic pole 3 is erected, a light source device 4 is attached to the upper end of the pole 3, and the light source device 4 is built inside a balloon 6 formed of a translucent sheet material.

(First Embodiment)
3 to 5 show a first embodiment of the present invention.

As shown in FIG. 3A, the balloon 6 is attached via the upper disc 5a and the lower disc 5b fixed to the upper and lower sides of the light source device 4, respectively, and this point is the same as that of the above-mentioned prior art. Is. However, the present invention does not have a structure in which the balloon 6 is inflated by the air pressure of the outside air as in the prior art, but a skeleton is formed by the elastic wire rod 8 provided on the balloon 6, whereby the balloon shape is formed in the radial direction. It is configured to retain its shape.

Therefore, the balloon-type floodlight of the present invention does not provide the electric blower 7 (see FIG. 2) as in the prior art, and does not require wiring for that purpose. As a result, the cost is low as a whole as compared with the conventional technique, and the weight is reduced, so that the handling is easy.

Since it is not necessary to prevent air from leaking from the inside of the balloon to the outside as in the prior art, the balloon 6 is freely removable from the light source device 4. Moreover, it is configured so that the air permeability around the light source device 4 is good, thereby preventing the temperature from rising.

In the illustrated embodiment, the balloon 6 is sewn with a translucent sheet material, has openings 6a and 6b at the top and bottom, and is formed into a shape having a maximum diameter in the central portion in the vertical direction. As a result, it is configured so that it can exhibit a shape that is generally in the shape of a balloon.

In order to maintain the shape of the balloon in the diameter direction, the elastic wire rod 8 is provided around the portion (D) having the maximum diameter of the balloon. As the elastic wire rod 8, it is preferable to use a plastic extruded material reinforced with fibers such as glass fiber and carbon fiber, that is, a wire rod having a circular cross section extruded by FRP.

In the case of the illustrated example, as shown in FIG. 3 (B), the elastic wire 8 is inserted into and accommodated in a storage chamber 9 formed of a bag-shaped passage formed along a portion (D) having the maximum diameter of the balloon 6. It is held inside the chamber 9. As a result, the elastic wire rod 8 is provided around the balloon 6 along the portion (D) having the maximum diameter, and both ends thereof are joined and connected by joints to form a circular ring as a whole.

In this state, the balloon 6 is attached to the light source device 4 to maintain the shape of the balloon in the vertical direction. The upper inward flange portion 10a formed in the upper opening 6a is locked to the peripheral edge of the upper disk 5a, and the lower inward flange 10b formed in the lower opening 6b is attached to the peripheral edge of the lower disk 5b. By locking to the part, it can be attached and detached.

In this mounted state, the balloon 6 is held in the radial direction by the elastic wire 8, and is held in the vertical direction by the upper and lower inward flange portions 10a and 10b that are locked and fixed to the upper and lower disks 5a and 5b. As a result, the shape as a whole is generally balloon-shaped.

As shown in FIG. 4, the lower inward flange portion 10b is provided with an opening / closing means 11 that allows the lower opening 6b to be expanded / contracted, so that the balloon 6 can be attached to and detached from the upper and lower disks 5a and 5b. The lower disk 5b is passed by expanding the portion 6b, and the lower opening 6b is contracted so as to be locked to the lower surface of the peripheral edge portion of the lower disk 5b.

In the illustrated embodiment, the opening / closing means 11 is composed of a slit 12 that divides the lower inward flange portion 10b, and split hem portions 13 and 13 on both sides of the slit. Therefore, the lower opening 6b is opened and expanded by opening the split hem portions 13 and 13 in the direction of separation from each other, and the lower opening 6b is contracted by closing each other. Further, fasteners 13a and 13b such as hook-and-loop fasteners are provided so that the split hem portions 13 and 13 are detachably fixed in a state of being closed to each other.

Preferably, as shown in the drawing, the drawstring string 14 is inserted into the bag-shaped passage formed in the lower inward flange portion 10b, the lower opening 6b is opened and expanded by loosening the string, and the lower opening 6b is squeezed. Is configured to be contracted, and the contracted state is configured to be held by the fastener 15.

(while using it)
The balloon 6 is attached to the light source device 4 when the balloon type floodlight is used. As described above, with the lower opening 6b expanded by the opening / closing means 11, the balloon 6 is placed on the light source device 4 from above until the upper inward flange portion 10a is placed on the upper disk 5a, and the state thereof. Then, the lower opening 6b may be contracted by the opening / closing means 11 and the lower inward flange portion 10b may be squeezed under the lower disk 5b, whereby the balloon 6 is attached to the light source device 4 and has a diameter. It is maintained in a balloon shape in the direction and up and down direction.

Since it is not necessary to seal the air inside the balloon so as not to leak to the outside as in the prior art, as shown in FIGS. 3 (B) and 3 (C), the upper and lower disks 5a and 5b have vent holes 16a and 16b. Is provided, which can prevent the light source device 4 from becoming hot.

(When not in use)
The balloon 6 is removed from the light source device 4 when it is stored without using the balloon type floodlight. The removal may be performed in the reverse operation of the mounting, and the balloon 6 can be pulled upward from the light source device 4 by expanding the lower opening 6b by the opening / closing means 11. As a result, the vertical shape retention of the balloon is lost.

Therefore, the elastic wire rod 8 that retains the shape of the balloon 6 in the diameter direction can be folded compactly as shown in FIG. Although the balloon 6 is not shown in FIG. 5 for convenience of explanation, it should be understood that the balloon 6 is also folded at the same time following the folding of the elastic wire rod 8.

As shown by arrows F1 and F2, the circular ring 8A made of the elastic wire 8 shown in FIG. 5 (A) is twisted and deformed in the opposite direction when the portions facing each other in the radial direction are twisted and deformed. It is self-retaining in a state of being deformed so as to form the 8-shaped ring 8B shown in. In the illustrated example, the case where F1 is twisted clockwise and F2 is twisted counterclockwise is shown, but the opposite direction may be used. Therefore, as shown by the arrow F3, the 8-shaped ring 8B has an overlapping circular shape in which two small circular rings as shown in FIG. 5C are overlapped when the intersection is bent and deformed in the folding direction. It is self-retaining in a deformed state so as to form the ring 8C.

As a result, the balloon 6 can be compactly folded by integrally deforming the circular ring 8A while the balloon 6 and the elastic wire 8 are removed from the light source device 4.

In this way, the balloon 6 is folded so as to have a diameter about half that of the state before folding. The balloon-type floodlight is usually accompanied by a soft case for storing the LED lamp when it is carried, and since the case is formed in a cylindrical shape, it is suitable for storing a folded balloon. Since the case has a lid that can be opened and closed in a circular shape, it is preferable to provide a pocket inside the lid so that the folded balloon can be stored in the pocket.

(Second Embodiment)
FIG. 6 shows a second embodiment of the present invention.

In the case of the first embodiment described above, the balloon 6 is formed by arranging one elastic wire rod 8 around the maximum diameter portion (D) located at the equator, but the second In the embodiment, the balloon 6 is located at the peripheral portion in the vicinity of the upper opening 6a and the lower opening 6b, respectively, to form the maximum diameter portions (D) and (D), and the elastic wires 8 and 8 are provided around the balloon 6. doing. Therefore, a cylindrical portion 6c having the same diameter is formed between the portions (D) and (D) having the maximum diameters held by the upper and lower elastic wires 8 and 8.

Since the other configurations are the same as those of the first embodiment described above, duplicate description will be omitted. As described above, the present invention retains the balloon 6 in a predetermined shape by the elastic wire rod 8. It should be understood that the number of elastic wire rods 8 is not a question.
