Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a light bulb socket cap holder which can be easily attached to and detached from a signal lamp with one hand.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 4, a signal lamp has a light-transmitting lens b attached to the front surface of the signal lamp a, the inner surface of the signal lamp a has a mirror surface, and a bulb c is provided at the base end of the signal lamp a. It is configured to be mounted.

[0005] Therefore, the bulb c is mounted on the bulb socket base d as shown in FIG. 5, and the bulb socket d is fitted into a rising portion e opened to the base end side of the signal lamp a. Further, a mechanism for fixing by means of holding metal fittings g, g attached to the reflecting plate f of the signal lamp a.

However, in the above mechanism, since the holding members g, g are attached to the reflecting plate f by the fastening members h such as screws, a part of the fastening members h is provided on the reflecting mirror i inside the signal lamp a. It will protrude, thereby reducing the reflection effect and the reflection efficiency.

Further, when the light bulb socket base d is mounted with the holding brackets g, g, the work may be performed while pressing the reflector f by hand, and the pressure may distort or damage the reflecting mirror i.

In order to solve the above-mentioned problems, the applicant of the present application has filed Japanese Utility Model Application No. Hei 5-35645 (bulb socket holder for a communication lamp). According to the present invention, as shown in FIGS. 6 and 7, the light bulb socket base 7a can be easily formed by manually pushing down the holding portions 6a, 6a of the upper elastic plate 1a from the state shown by the imaginary line in the figures. It can be fitted and connected to the bulb socket base fitting hole 9a.

[0007] Thereafter, the urging force of the lower elastic plate 2a constantly exerts a force to push the upper elastic plate 1a upward, whereby the mooring portions 5a, 5a at both ends of the upper elastic plate 1a are applied. As a result, an inward force acts to maintain the engagement with the locking portion 11a.

In order to release the engagement between the mooring portions 5a, 5a and the locking portion 11a, the pressing portions 6a, 6a of the upper elastic plate 1a are simply pushed downward by hand again, thereby easily. It can be released.

[0009]

[Problems to be solved by the invention]

 However, in the work of replacing a light bulb with the light bulb socket cap holding fixture of the above mechanism, the holding parts 6a, 6a must be pressed down strongly by hand, and the holding parts 6a, 6a must be evenly pressed. However, there is a problem that replacement work under unstable conditions becomes very complicated.

In view of the above, an object of the present invention is to provide a light bulb socket cap holder which can be easily attached and detached with one hand in order to solve the above-mentioned problems.

[0011]

[Means for Solving the Problems]

 The above object of the present invention can be achieved by a holding member having the following configuration. That is, the gist of the thin steel sheet is to hold the light bulb socket base fitting hole that is opened at the base end side of the signal lamp and the light bulb socket base that has the socket storage tube projected from the center. In the center of the curved elastic plate formed by the above, a socket storage tube insertion hole through which the above-mentioned socket storage tube can be freely inserted is penetrated, and both ends are bent downward, and the tip is further inside. And the diameter between the mooring portions is made smaller than the diameter of the bulb socket base, and the diameter between the mooring portions is freely set between both ends of the elastic plate and the socket storage tube insertion hole. A traffic light bulb light bulb socket cap retainer characterized by projecting a rising plate portion which can be expanded in diameter.

[0012] The socket insertion hole and the rising plate portion are formed by punching. Further, it is necessary to maintain a rising angle with the elastic plate in order to adjust the diameter between the mooring portions by sandwiching the rising plate portion by hand and pushing down the elastic plate between the rising plate portions downward to adjust the diameter with the mooring portion. For this purpose, a mechanism that has been subjected to press processing as reinforcement in the same manner as punching processing is used.

[0013]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings showing the embodiments. As shown in FIG. 1, the holding member 1 has a hole 3 for inserting a socket storage tube through the center of a curved elastic plate 2 formed of a thin steel plate.

The total length of the elastic plate 2 is smaller than the diameter of the bulb socket base, and both ends of the elastic plate 2 are bent downward, and the ends thereof are bent inward to form the mooring portions 4, 4. 4.

Further, rising plate portions 5 and 5 which are bent outward are provided on both peripheral portions of the socket insertion holes 3 between the mooring portions 4 and 4.

Therefore, as shown in FIG. 2 and FIG. 3, the bulb socket base 6 is fitted into the bulb socket base fitting hole 9 of the signal lamp 8, and the circumferential edge 10 of the bulb socket base 6 and the bulb socket base are fitted. The opening edge 11 of the fitting hole 9 is made to overlap.

Then, the socket storage tube insertion hole 3 of the holding metal fitting 1 is inserted into the socket storage tube 7 of the light bulb socket base 6, and the rising plate portions 5, 5 are drawn together with one hand. The diameter of the space between the mooring portions 4 and 4 is increased by being sandwiched, and the circumferential edge 10 of the bulb socket base 6 and the opening edge 11 of the bulb socket fitting hole 9 are locked by the mooring portions 4 and 4. By releasing the rising plate portions 5, 5, the diameter of the mooring portions 4, 4 is reduced by the restoring force of the elastic plate 2, and the bulb socket base 6 and the bulb socket fitting hole 9 can be firmly mounted. is there.

When the bulb socket base 6 is to be removed, the rising plates 5, 5 of the holding fixture 1 are sandwiched with one hand, and the diameter of the mooring parts 4, 4 is increased. This is a mechanism that can easily release the engagement of the socket base fitting hole 9 with the opening edge 11.

[0019]

[Effect of the invention]

 As described above, according to the present invention, the attachment and detachment of the bulb socket base by the holding bracket can be easily performed with one hand, and the efficiency of replacement work in a place where the working environment is unstable can be improved.
