Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a socket used when connecting a lamp.

[0002]

[Prior Art]

 In the conventionally known lamp socket for axially attaching and detaching the fluorescent lamp, when the fluorescent lamp is replaced, for example, in the case of the fluorescent stand shown in FIG. 9, the lamp socket 23 is integrated with the shade 24. When replacing the lamp 16, the large cap was required so that the lamp 16 would not hit the cap 24. Also, in the case of a recessed electric lamp on the ceiling in a room, the recess had to be designed large, including the lamp pull-out.

[0003]

[Problems to be solved by the device]

 The purpose of the present invention is to mount the lamp in a narrow and limited space by rotating the lamp socket with respect to the holder and tilting it when changing the lamp to change the lamp take-out direction. Another object is to provide a lamp socket that makes it easy to attach and detach the lamp without being hindered by the peripheral wall.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the lamp socket of the present invention has a socket part provided with a lamp mounting part for detachably mounting the lamp, and the socket part is attached to the holder in a direction intersecting the mounting direction of the lamp. It is rotatably mounted around the axis of, and at least one of the holding body and the socket portion is provided with an engaging / disengaging device for engaging and disengaging the holding body and the socket portion.

[0005]

[Action]

 When the socket part is rotated around an axis line in a direction intersecting with the mounting direction of the lamp, the socket part is disengaged from the engaging / disengaging device, and in this state the lamp is attached / detached to / from the socket part.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, the socket portion 1 made of electrically insulating synthetic resin is provided with a lamp mounting portion for detachably mounting the lamp 16 in its axial direction, and as shown in FIG. 2 and FIG. The parts 9 and 10 are internally provided, and the electrode parts 9 and 10 are connected to the electrodes on the lamp side. Then, the socket part 1 is fixed to the first bent part 19 of the socket part mounting member 4 made of sheet metal by the socket part fixing screws 11 and 12 (FIGS. 4, 6, and 8), and further for socket part mounting. The member 4 is rotatably attached to the holder 2 via a support shaft 8 in a direction intersecting with the lamp attaching direction, and the socket portion attaching member 4 has a first bent portion 19 attached thereto. A second bent portion 20 is formed so as to face (FIGS. 4, 5, and 6). Further, locking recesses 6 are provided on both side surfaces of the socket portion 1 so as to face each other, and when the locking recesses 6 are locked by the engagement / disengagement device 3 described later, the engagement recesses 7 of the engagement / disengagement device 3 are provided. This is the place to lock.

The holding body 2 is formed by molding a metal plate, has a mounting hole 14 formed in the upper surface thereof as shown in FIG. 3, and has a substantially square cross section from the front side as shown in FIG. In addition, the mounting side 13 having the socket portion 1 therein and the mounting hole 15 is provided on the outer side of the socket portion 1 so as to project. In addition, a notch 21 for passing a power cord from the socket portion 1 is provided on the back surface in a substantially square shape at the center of the back surface, and stoppers are bent outward on both sides at the substantially center position. 5 is formed.

Further, the engagement / disengagement device 3 is formed into a substantially U-shape by an elastic narrow metal piece, and has a pair of sandwiching members that face each other so as to abut the side surface portion of the socket portion 1. Each of the sandwiching pieces 17 is provided with a locking projection 7 that is convex inward and is engaged with the locking recess 6 of the socket 1. As shown in, the central portion is fixed to the holding body 2 and is stopped by the tacks 18.

The stopper 5 is press-molded integrally with the holding body 2, and when the socket portion 1 and the socket portion mounting member 4 are integrally rotated around the support shaft 8, the stopper portion 5 is mounted. It is configured to contact the second bent portion 20 of the member 4 and hold the socket portion 1 with respect to the holding body 2 at a predetermined angle.

The operation when replacing the lamp will be described below.

As shown in FIG. 8, the socket 1 with the lamp 16 mounted thereon has the engaging projection 7 of the engaging / disengaging device 3 and the engaging recess 6 of the socket 1 aligned with each other and is attached to the holder 2. It is locked. As shown in FIG. 1, when a force is applied in the direction of pulling the lamp 16 downward, the socket portion mounting member 4 to which the socket portion 1 is attached tends to rotate around the support shaft 8 and the engagement of the socket portion 1 is prevented. The locking concave portion 6 tends to shift from the locking convex portion 7 of the engagement / disengagement device 3, and the locking convex portion 7 presses against the edge of the locking concave portion 6. Since the engagement / disengagement device 3 has elasticity, the engagement / disengagement device 3 expands little by little. When further force is applied, the engagement recess 6 and the engagement protrusion 7 are completely separated from each other, and the socket portion 1 is disengaged from the engagement / disengagement device 3. It becomes free to move, and the second bent portion 20 of the socket portion mounting member 4 comes into contact with the stopper 5 formed at one end of the holding body 2 and stops. In this way, the socket portion 1 with the lamp 16 mounted is turned obliquely downward. Here, the lamp 16 may be pulled out from the socket 1 and replaced. After replacing the lamp 16, the socket 1 is pushed upward until the locking concave portion 6 of the socket 1 and the locking convex portion 7 of the engaging / disengaging device 3 are aligned, and the locking concave portion 6 and the locking convex portion 7 again. The part 7 is locked.

Further, as shown in FIGS. 10 and 11, the mounting hole 14 is used when the holding body 2 is mounted from below the device 22, and the mounting hole 15 is used when mounting from the upper side of the device 22. Although the engaging / disengaging device 3 is attached to the holding body 2 in the above-described embodiment, the engaging / disengaging device 3 may be provided in the socket 1 so as to be engaged / disengaged with respect to the holding body.

[0014]

[Effect of the device]

 According to the lamp socket of the present invention, when the lamp is attached or detached, the socket part is rotated and tilted with respect to the holding body to change the taking-out direction of the lamp. Even if it is attached, the lamp can be attached and removed quickly and easily without being disturbed by the surrounding wall. For example, in the case of a fluorescent stand, the size of the shade can be made smaller than that of the conventional one, and in the case of a recessed type electric lamp such as the ceiling in the room, Since it is not necessary to design the recess to be large including the lamp pull-out part, the space of the recess can be reduced when designing the room or corridor, which leads to compact interior lighting.
