Description

本発明は、支持部の上側で膨張・収縮自在な透光性を備えたバルーンと、そのバルーンの内側に収容してある光源用電球とを前記支持部の上部に固定可能に設け、前記バルーンに膨張用空気を供給可能な給気装置を設けてある照明器具に関する。   The present invention provides a balloon having translucency that can be inflated and contracted on the upper side of the support part, and a light source bulb housed inside the balloon so as to be fixed to the upper part of the support part. The present invention relates to a lighting fixture provided with an air supply device capable of supplying expansion air.

上記照明器具は、電球の光が膨張状態のバルーンを通して照射されるので、夜間の道路工事などにおいて使用しても、通行車両の運転者が感じる眩しさを和らげることができるとともに、非使用時にはバルーンを収縮させて保管したり運搬できる利点があるが、従来、バルーンの内側で電球の周囲を囲む保護枠を支柱などの支持部の上端側に固定可能に設け、膨張状態のバルーンの風などによる支持部に対する姿勢変化を規制するために、その保護枠を利用して、バルーンの膨張状態でその上面部位と下面部位とに対応する箇所を保護枠の上下両端部に固定している（例えば、特許文献１参照）。   Since the light from the light bulb is irradiated through an inflated balloon, the above-mentioned lighting fixture can relieve the glare felt by the driver of a passing vehicle even when used in road construction at night, etc. There is an advantage that it can be stored and transported by contracting, but conventionally, a protective frame surrounding the bulb around the inside of the balloon can be fixed to the upper end side of the support part such as a support column, etc. In order to regulate the posture change with respect to the support portion, the protective frame is used to fix the portions corresponding to the upper surface portion and the lower surface portion to the upper and lower ends of the protective frame in the inflated state of the balloon (for example, Patent Document 1).

特開２００３−３６７０９号公報JP 2003-36709 A

このため、非使用時にバルーンを収縮させると、バルーンの水平方向に沿う外径は小さくすることができるものの、バルーンの膨張状態でその上面部位と下面部位とに対応する箇所を保護枠の上下両端部に固定してあるので、バルーンの上下方向高さは変えることができず、大きく膨張させるバルーンを設けるほど、非使用時においてバルーンを収縮させても、照明器具全体のコンパクト化を図りにくい欠点がある。
本発明は上記実情に鑑みてなされたものであって、膨張状態のバルーンの支持部に対する姿勢変化を規制できるようにしながら、非使用時にバルーンを収縮させたときに、照明器具全体のコンパクト化を図り易くすることを目的とする。 For this reason, when the balloon is deflated when not in use, the outer diameter along the horizontal direction of the balloon can be reduced, but in the inflated state of the balloon, the portions corresponding to the upper surface portion and the lower surface portion are located at the upper and lower ends of the protective frame. The height of the balloon cannot be changed because it is fixed to the part, and the more the balloon that is inflated, the more difficult it is to make the entire lighting fixture compact even when the balloon is deflated when it is not in use. There is.
The present invention has been made in view of the above circumstances, and when the balloon is deflated when not in use, the overall lighting apparatus can be made compact while allowing the posture change with respect to the support portion of the inflated balloon to be regulated. It aims at making it easy to plan.

本発明の第１特徴構成は、支持部の上側で膨張・収縮自在な透光性を備えたバルーンと、そのバルーンの内側に収容してある光源用電球とを前記支持部の上部に固定可能に設け、前記バルーンに膨張用空気を供給可能な給気装置を設けてある照明器具であって、膨張状態のバルーンの前記支持部に対する姿勢変化をその外面側から規制可能な規制フレームを、前記光源用電球周りで、膨張状態のバルーンの下向き外面側にのみ略沿わせる状態で設けてある点にある。   The first feature of the present invention is that a balloon having translucency that can be expanded and contracted on the upper side of the support part and a light source bulb accommodated inside the balloon can be fixed to the upper part of the support part. A lighting device provided with an air supply device capable of supplying inflation air to the balloon, wherein a regulation frame capable of regulating a change in posture of the balloon in an inflated state with respect to the support portion from an outer surface side thereof, Around the light source bulb, it is provided so as to be substantially along the downward outer surface side of the inflated balloon.

〔作用及び効果〕
膨張状態のバルーンの支持部に対する姿勢変化を、規制フレームでその外面側から規制できるので、非使用時にバルーンを収縮させるときに、そのバルーンの収縮に対して規制フレームが干渉しにくくなり、バルーンを小さく収縮させ易いとともに、規制フレームを、光源用電球周りで、膨張状態のバルーンの下向き外面側にのみ略沿わせる状態で設けてあるので、規制フレームの上下方向寸法も嵩張りにくい。
従って、膨張状態のバルーンの支持部に対する姿勢変化を規制できるようにしながら、非使用時にバルーンを収縮させたときに、照明器具全体のコンパクト化を図り易い。 [Action and effect]
Since the posture change with respect to the support portion of the inflated balloon can be regulated from the outer surface side by the regulation frame, when the balloon is deflated when not in use, the regulation frame is less likely to interfere with the deflation of the balloon. In addition to being small and easy to contract, the restriction frame is provided so as to be substantially along the downward outer surface side of the inflated balloon around the light source bulb, so that the vertical dimension of the restriction frame is also difficult to be bulky.
Therefore, it is easy to make the entire lighting fixture compact when the balloon is deflated when not in use, while the posture change with respect to the support portion of the inflated balloon can be regulated.

本発明の第２特徴構成は、前記規制フレームを構成するに、複数の規制アームを、膨張状態のバルーンの下向き外面側に略沿うように展開する展開姿勢と、先端側が互いに近接するように格納する格納姿勢とに姿勢切換自在に設けて構成してある点にある。   According to a second characteristic configuration of the present invention, when the restriction frame is configured, the plurality of restriction arms are stored so that the deployment posture in which the plurality of restriction arms are expanded substantially along the downward outer surface side of the inflated balloon and the distal end side are close to each other. It is in the point that it is provided so that the posture can be freely switched to the retracted posture.

A deployment frame in which a posture of the inflated balloon with respect to the support portion can be regulated from the outer surface side, a plurality of regulating arms are deployed so as to be substantially along the downward outer surface side of the inflated balloon, and the distal end side is mutually Since the posture is freely switchable to the retracted posture for storing in a close proximity, when the balloon is inflated, a plurality of restricting arms are deployed so as to extend substantially along the downward outer surface side of the inflated balloon. Switch to a retracted posture in which a plurality of restricting arms are retracted so that the distal end sides are close to each other when not in use when the balloon is deflated while switching the posture from the outer surface side while regulating the posture change with respect to the support portion of the inflated balloon. Thus, it is easy to further reduce the overall size of the lighting fixture.

本発明の第３特徴構成は、前記複数の規制アームを上下揺動自在に支持して、前記規制姿勢と前記格納姿勢とに姿勢切換自在に設けてある点にある。   A third characteristic configuration of the present invention is that the plurality of restriction arms are supported so as to be swingable up and down, and the posture can be switched between the restriction posture and the retracted posture.

〔作用及び効果〕
規制フレームを構成している複数の規制アームを上下揺動自在に支持して、規制姿勢と格納姿勢とに姿勢切換自在に設けてあるので、姿勢切換操作の簡略化を図ることができる。 [Action and effect]
Since the plurality of restriction arms constituting the restriction frame are supported so as to be swingable up and down, and the posture can be switched between the restriction posture and the retracted posture, the posture switching operation can be simplified.

本発明の第４特徴構成は、前記光源用電球を、クセノンショートアークランプで構成してある点にある。   A fourth characteristic configuration of the present invention is that the light source bulb is configured by a xenon short arc lamp.

〔作用及び効果〕
光源用電球を、水銀ランプなどに比べて瞬時に再点灯させ易いクセノンショートアークランプで構成してあるので、所望のタイミングで再点灯させ易い。 [Action and effect]
