Description

【０００１】
【発明の属する技術分野】
本発明は、天井面に水平に固定される器具本体を備え、前記器具本体に固定されるプルスイッチを備え、前記プルスイッチから前記器具本体に沿って水平に延び、前記器具本体の周縁部から垂下される操作紐を備えた天井用照明器具の引紐装置に関するものである。
【０００２】
【発明が解決しようとする課題】
この種装置においては、操作紐の張力および引紐ストローク（引く長さ）を調整するために、操作紐をプルスイッチ側から延びるスイッチ側紐部と引き紐操作側引紐部とに分け、その間を中継する金属製レバーを設ける。
しかし、各引紐部を金属製レバーに装着する作業に手間がかかり、また装着箇所で紐が切断する可能があった。
本発明の目的は紐の装着が簡単であって、また紐が切断し難い構造の天井用照明器具の引紐装置を提供することである。
【０００３】
【課題を解決するための手段】
天井用照明器具の引紐装置は水平に固定される器具本体と前記器具本体に固定されるプルスイッチを備える。前記プルスイッチから前記器具本体に沿って水平に延び、前記器具本体の周縁部から垂下される操作紐を備える。
本発明においては、前記器具本体に前記操作紐を中継する回転レバーを配置する。前記回転レバーはレバー本体と該レバー本体の片面一端に配置した回転軸部と該レバー本体の他の片面に該レバー本体の長手方向に沿って配置した一対の紐留め突起とを合成樹脂で一体に形成したものである。前記各紐留め突起に紐を着脱自在に係合する紐留めスリットを形成する。前記器具本体に前記回転軸部を回転自在にかつ着脱自在に枢着するだるま孔を設ける。
前記操作紐における前記プルスイッチ側から延びるスイッチ側紐部の他端を一方の前記紐留め突起の前記紐留めスリットの箇所に係合する。前記操作紐における引き紐操作側引紐部の基端を他方の前記紐留め突起の前記紐留めスリットの箇所に係合する。
【０００４】
【発明の実施の形態】
図１〜図３を使って本発明の実施形態について説明する。本発明に係る天井用照明器具の引紐装置は天井面に水平に固定される器具本体６を備える。器具本体６に固定されるプルスイッチ８を備える。プルスイッチ８から器具本体１に沿って水平に延び、器具本体１の周縁部から垂下される操作紐を備える。
器具本体６に操作紐を中継する回転レバー２０を配置する。回転レバー２０はレバー本体１と該レバー本体１の片面一端に配置した回転軸部２と該レバー本体１の他の片面に該レバー本体１の長手方向に沿って配置した一対の紐留め突起４・５とを合成樹脂で一体に形成したものである。各紐留め突起４・５に紐を着脱自在に係合する紐留めスリット３を形成する。器具本体６に回転軸部２を回転自在にかつ着脱自在に枢着するだるま孔７を設ける。
操作紐におけるプルスイッチ８側から延びるスイッチ側紐部９の他端を一方の紐留め突起４の紐留めスリット３の箇所に係合する。操作紐における引き紐操作側引紐部１０の基端を他方の紐留め突起５の紐留めスリット３の箇所に係合する。引き紐操作側引紐部１０を引紐操作すると、レバー本体１が回転軸部２回りに回転し、スイッチ側紐部９も引かれるが、それらの張力と引紐ストロークは各紐留め突起４・５の回転半径比に応じて変換される。プルスイッチ８の特性によっては、スイッチ側紐部９を紐留め突起５に係合し、引き紐操作側引紐部１０紐留め突起４に係合することが好適である場合もある。
回転レバー２０はその回転軸部２を器具本体６のだるま孔７に装着すれば良いので、装着作業が簡単である。また、各紐部９・１０をスリット３に挟み込む構造であるため、その装着も簡単である。また、回転レバー２０は合成樹脂で一体に形成したものであり、安価である。また、各紐部９・１０に当たる鋭利な箇所もないため、各紐部９・１０が切断し難い。スリット３の入り口をテーパー状に形成し、奥を膨大部となる形態とするが、それは各紐部９・１０の装着が簡単であって、かつ外れ難くするためである。
【０００５】
【発明の効果】
本発明は以上のように構成したので、回転レバーの装着が簡単であり、紐の装着も簡単であり、また紐が切断し難い構造となる。

BACKGROUND OF THE INVENTION
The present invention includes an instrument main body that is horizontally fixed to a ceiling surface, includes a pull switch that is fixed to the instrument main body, extends horizontally from the pull switch along the instrument main body, and from a peripheral portion of the instrument main body. The present invention relates to a drawstring device for a ceiling luminaire provided with a hanging operation string.
[0002]
[Problems to be solved by the invention]
In this kind of device, in order to adjust the tension and pulling stroke (pulling length) of the operation string, the operation string is divided into a switch side string part extending from the pull switch side and a pull string operation side pull string part, and relaying between them. Provide a metal lever.
However, it takes a lot of time to attach each drawstring portion to the metal lever, and the cord may be cut at the attachment location.
An object of the present invention is to provide a pulling device for a lighting device for a ceiling having a structure in which a string can be easily attached and the string is difficult to cut.
[0003]
[Means for Solving the Problems]
A pulling device for a ceiling lighting fixture includes a fixture main body fixed horizontally and a pull switch fixed to the fixture main body. An operation string is provided that extends horizontally from the pull switch along the instrument body and hangs down from the peripheral edge of the instrument body.
In this invention, the rotation lever which relays the said operation string is arrange | positioned at the said instrument main body. The rotating lever is integrally formed of a synthetic resin with a lever body, a rotating shaft portion disposed at one end of the lever body, and a pair of stringing protrusions disposed along the longitudinal direction of the lever body on the other surface of the lever body.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to FIGS. The drawstring device for a ceiling lighting fixture according to the present invention includes a fixture body 6 that is horizontally fixed to a ceiling surface. A pull switch 8 fixed to the instrument body 6 is provided. An operation string that extends horizontally from the pull switch 8 along the instrument body 1 and hangs down from the peripheral edge of the instrument body 1 is provided.
A rotation lever 20 that relays an operation string is disposed on the instrument body 6. The rotating lever 20 includes a lever body 1, a rotating shaft portion 2 disposed at one end of the lever body 1, and a pair of stringing protrusions 4 disposed along the longitudinal direction of the lever body 1 on the other surface of the lever body 1. -5 and are integrally formed of synthetic resin. A stringing slit 3 for detachably engaging the string with each of the stringing protrusions 4 and 5 is formed. The device body 6 is provided with a daruma hole 7 on which the rotary shaft 2 is pivotably and detachably mounted.
The other end of the switch side string portion 9 extending from the pull switch 8 side of the operation string is engaged with the string retaining slit 3 of one of the string retaining projections 4. The base end of the pull string operating side pull string portion 10 in the operation string is engaged with the string lock slit 3 of the other string lock projection 5. When the drawstring operation side drawstring part 10 is drawn, the lever body 1 rotates around the rotary shaft part 2 and the switch side string part 9 is also pulled. However, the tension and drawstring stroke of each of the stringing protrusions 4 and 5 It is converted according to the rotation radius ratio. Depending on the characteristics of the pull switch 8, it may be preferable to engage the switch side string portion 9 with the string holding projection 5 and engage the draw string operation side draw string portion 10 with the string holding projection 4.
Since the rotation lever 20 should just mount the rotating shaft part 2 in the daruma hole 7 of the instrument main body 6, attachment work is easy. In addition, since the string portions 9 and 10 are sandwiched between the slits 3, the attachment is easy. Further, the rotary lever 20 is integrally formed of synthetic resin and is inexpensive. Moreover, since there is no sharp part which hits each string part 9 * 10, each string part 9 * 10 is hard to cut | disconnect. The entrance of the slit 3 is formed in a taper shape, and the back is a large portion. This is because each of the string portions 9 and 10 is easy to attach and difficult to come off.
[0005]
【The invention's effect】
Since the present invention is configured as described above, the rotation lever can be easily mounted, the string can be easily mounted, and the string is difficult to cut.
