[Industrial applications]

 The present invention relates to an improvement in a connecting structure of a drawstring integrally connected with a switch for connecting a power source of a lighting fixture.

[0002]

[Prior art]

 Conventionally, when connecting a drawstring that is integrally connected to a switch to connect the power supply of a lighting fixture, the drawstring that allows the user to connect the switch directly to the switch body built into the lighting fixture is connected. However, the length of the drawstring that hangs outside the luminaire differs depending on the tolerance of the drawstring itself and the relationship of the switch mounting position, which may cause a deterioration in appearance and inconvenience to the user. Therefore, in some cases, the drawstring was divided, a pulling wheel plate was placed in the middle of the drawstring to adjust the entire length of the drawstring to the same length, and the drawstrings were integrally connected.

However, in the case of the above-mentioned conventional one, in which the drawstring is divided and a drawstring plate is arranged in the middle of the drawstring, and the length of the drawstring is adjusted by tying the drawstring to the drawstring plate, The structure is simple, the cost is low, and if the error of the drawstring is within a certain range, it is possible to adjust it without spoiling the appearance of the lighting fixture. If the error to be adjusted becomes large, the length of the drawstring tied to the drawstring plate will become large, and the tied drawstring will hang outside the luminaire, which may impair the appearance of the luminaire. In order to adjust the length of the drawstring to a certain extent, it is necessary to repeatedly tie the drawstring to the draw wheel plate, which is very complicated and the work time required for adjusting the drawstring is increased. Big However, there is a drawback that the work efficiency is lowered.

Therefore, a locking body integrally attached to the tip of the cord body that is directly pulled out from the switch has a hole for connecting the pull cord at one end, and a locking tooth portion that is engageable only in the pulling direction at the other end. By adjusting the position of the adjusting device by sliding the stopper, it is possible to adjust the length of the drawstring by pressing it between the legs of the adjusting device consisting of the legs with A drawstring adjustment device that can do this was proposed.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned one, since the locking body is press-fitted between the legs of the adjusting device body and held and fixed by the stopper, the distance between the locking body and the legs and the locking teeth are If the stopper dimensions are not adjusted properly, obstacles such as insecure fixation of the locking body or difficulty in sliding the stopper will occur. The manufacturing of each component requires accuracy, which has a drawback of increasing cost. Further, when the drawstring adjusting device of the above invention is used, the locking teeth and the stopper are exposed to the outside, so that there is a drawback in that the appearance of the lighting fixture is impaired.

Therefore, the present invention aims to improve the drawbacks of the above-mentioned conventional ones, and to reduce the manufacturing cost of the drawstring adjusting device with a simple structure and to improve the aesthetic appearance of the entire lighting fixture.

[0007]

[Means for Solving the Problems]

 Therefore, at one end, the main body of the adjustment device and the main body of the adjustment device, which are connected to the cord body that is directly pulled out from the switch of the luminaire and in which a plurality of engaging portions of the same shape are arranged at equal intervals in the longitudinal direction, are provided. For a switch that is configured by a cover body and a locking body that has a protrusion that can be engaged between the engaging portions, and that is hung outside the lighting equipment between any engaging portions inside the adjustment device body. The switch and drawstring are integrated by engaging the protrusion of the locking body attached to the end of the drawstring and hanging the switch drawstring outside the adjustment device body, and locking the lid to the adjustment device body. It is connected to.

[0008]

[Action]

 With the above configuration, when adjusting the length of the switch drawstring that hangs outside the lighting equipment, if the switch drawstring is long, the lock attached to the end of the switch drawstring that hangs outside the lighting equipment. The body is engaged between the protruding part and the engaging part existing on the upper side of the engaging part provided inside the adjusting device main body, and then the switch drawstring is hung downward from the lower part of the adjusting device main body to adjust. It can be fixed by engaging the lid with the main body of the device, and the switch drawstring will be pulled up together with the locking body above the main body of the adjustment device, shortening the length of the switch drawstring hanging outside the lighting equipment. On the other hand, when the drawstring for the switch is short, the locking body is engaged between the protrusion and the lower engaging part of the engaging parts provided inside the adjusting device body. In addition to the above It can be fixed by engaging the lid with the adjustment device body in the same manner, and the switch drawstring will be pulled down together with the locking body to the bottom of the adjustment device main body. The length can be lengthened.

Moreover, since the locking body engaged with the adjusting device main body is fixed by engaging the lid body with the adjusting device main body, the engagement portion between the adjusting device main body and the locking body is removed. The fitting does not require strictness, and since the engaging portion is covered with the lid, it is possible to improve the aesthetic appearance of the entire lighting fixture.
