Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a balloon lighting device that can be used at a construction site, a parking lot, an event site, or at nighttime work, rescue and rescue.

[0002]

[Prior art]

 A luminaire in which air or helium gas is introduced into a balloon having a diameter of several tens cm to several meters and having a built-in light source, inflated, and supported by columns or ropes and raised high in the air, has already been disclosed in JP-A-8-44308. And Japanese Patent Application Laid-Open Nos. 9-306210 and 10-188622. In this lighting device, the light source is surrounded by balloons, so the light is softened and there is no glare.In addition, since it is illuminated from a high place, there is no shadow and the light can be cast over a wide area. is there.

[0003]

[Problems to be solved by the invention]

 In such a balloon-shaped lighting device, it is necessary to support the balloon in a gas-tight manner. Usually, a method is adopted in which the lower end opening of the balloon is fixed to the base of the light source support in a gas-tight manner. For example, in Japanese Patent Application Laid-Open No. 8-44308, a method is adopted in which the opening edge of a balloon is sandwiched between two upper and lower ring-shaped collars. However, in this method, it is clamped with a collar and then tightened with bolts, so it takes time to remove and attach the balloon when replacing it, and it takes about one hour to work, and a special tool And the need for specialized skills. In addition, a hole for the bolt is provided in advance at the opening edge of the balloon, but the position of the hole is shifted, and if the hole is drilled again, the strength of the balloon is reduced. There is also.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a balloon-type lighting device that can easily perform a balloon attaching / detaching operation in a short time.

[0005]

Means for Solving the Problems The technical means of the balloon-shaped lighting device of the present invention includes a balloon made of a translucent and impermeable sheet material, and a ring-shaped mouth provided at the opening of the balloon. A light source bulb provided in the balloon, a light source support for supporting the light source bulb, an annular groove provided at the base of the light source support, and support means for raising the balloon at a high place, The ring-shaped opening is made of a stretchable elastic material, and the opening is fitted and fixed in an annular groove of the light source support.

The ring-shaped mouth is preferably made of latex rubber.

[0007]

[Embodiment of the invention]

 An embodiment of the balloon-shaped lighting device according to the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a support type. The balloon 1 has a diameter of about 50 cm to 5 m, preferably 80 cm to 3 m, and is made of a light-transmitting, thin, light, strong, impervious sheet material, for example, a sheet material made of polyester resin. Have been. The sheet material of the balloon 1 does not need to be a single sheet material, and it is possible to use a different sheet material for air permeability and strength, etc., to form a double structure. The lower end of the balloon 1 has an opening, and a ring-shaped mouth portion 2 made of an elastic material is attached. In the embodiment, terrax rubber is used as the material because it has good stretchability and heat resistance, is excellent in workability, and is resistant to perforation during sewing. The rim of the balloon 1 and the mouth 2 are firmly fixed by a double stitching method.

Reference numeral 3 denotes a light source located at the center of the balloon, and a halogen lamp or arc light of about 500 to 3000 W is usually used. The light source bulb 3 is attached to the upper end of a light source support 4 having an elongated shape. A small pump (not shown) is accommodated in the light source support 4 and sends out a gas such as air or helium gas (air in the embodiment) to inflate the balloon 1. An annular groove 5 is provided in the lower end base of the light source support 4, and the mouth 2 of the balloon fits into the groove 5. As a result, the connection is stable in the fitted state, and the mouth portion 2 can be firmly fixed without causing displacement.

Reference numeral 6 denotes a support, which is usually about 3 to 10 m in length, and which stands upright from the ground. The light source support 4 is attached to the upper end of the column 6. 7 is a supporter that supports the outer wall surface of the balloon 1, and 8 is a power distribution line, which is connected to a general commercial line, a generator, a storage battery, and the like. If the balloon 1 is inflated with helium gas and levitated in the air, it is possible to support the balloon with a rope or the like instead of the strut 6, which is advantageous, for example, when the balloon 1 is raised at a higher position. It is.

According to the above-described lighting device, if the balloon 1 is inflated, raised at a high place, and the light source bulb 3 is turned on, it illuminates a wide area with a gentle light without glare, without forming a shadow. be able to. The balloon 1 is supported by a method in which the elastic opening 2 provided at the lower end opening is fitted and fixed in the annular groove 5 of the light source support base. Can be performed easily and in a short time, and since the mouth 2 is supported by the groove 5, it can be stably supported without displacement.

The present invention is not limited to the above embodiment, but can be freely modified and implemented within the scope of the claims of the present invention. In particular, the material of the balloon 1 and the mouth 2, the type of the light source bulb 3, the method of forming the annular groove 5, and the type of the balloon supporting means such as the column 6 are arbitrary.

[0012]

[Effect of the invention]

 In the balloon lighting device of the present invention, the fixed support of the balloon is fixed by fitting a ring-shaped opening made of elastic material provided at the opening of the balloon into the annular groove of the light source support. The balloon can be easily attached and detached, and the replacement of the balloon can be performed much easier and in a shorter time than the conventional one. Further, since the mouth is fixed by the annular groove, there is an advantage that the balloon can be stably supported without causing displacement or the like.

According to the second aspect of the present invention, since the mouth is made of latex rubber, the mouth is rich in elasticity, easy to put on and take off, has high heat resistance, is durable, and has high strength against sewing and the like. It has excellent effects such as.
