Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a packaging device suitable for packaging a lighting fixture using a U-shaped fluorescent lamp.

[Conventional technology]

In addition to conventional U-shaped bent fluorescent lamps with wide cap spacing, as shown in Figure 5, a single cap 1
Recently, a highly efficient U-shaped fluorescent lamp 3 has been provided, which is formed by connecting both ends of a glass bulb 2 which is elongated and bent into a U-shape such that the walls of the bulb touch each other.
This type of U-shaped fluorescent lamp 3 is used by detachably inserting the base 1 into the lamp socket 4 shown in FIG. Convex portion 5 and lamp socket 4
This is achieved by engagement with a lamp holder 6 made of a leaf spring attached to the inside of both ends. The spring force of the lamp holder 6, which determines the lamp holding force, is set to an appropriate size that is not too strong, taking into consideration operability so that the U-shaped fluorescent lamp 3 can be easily attached and detached with a single touch. ing.

By the way, in the case of conventional packaging equipment for lighting equipment that uses such U-shaped fluorescent lamps, if the U-shaped fluorescent lamp is packaged with it connected to the lamp socket, it may cause problems during transportation or handling. Due to the springiness of the lamp holder as described above, there is a high possibility that the U-shaped fluorescent lamp will come off from the lamp socket and be damaged due to the applied impact or vibration.

For this reason, conventionally, the U-shaped fluorescent lamp was removed from the lamp socket of the lighting fixture body and packaged in an individual packaging box, and this individual packaging box was housed in the packaging box that accommodated the lighting fixture body.

[Problem that the invention attempts to solve]

However, as described above, the conventional packaging structure that uses individual packaging boxes exclusively for U-shaped fluorescent lamps has the problem of high packaging costs because packaging materials are wasted and packaging requires more time. Another problem is that the U-shaped fluorescent lamp must be connected to the lamp socket of the lighting fixture after unpacking.

[Means for solving problems]

The packaging device of the present invention connects a lighting equipment body which is equipped with a substantially rectangular lamp enclosing part and has a lamp socket fixed to one side wall of the enclosing part, by inserting a U-shaped fluorescent lamp into the socket. The lamp buffer includes a packaging container that is stored in a bent state, and a lamp buffer that is stored in the lamp surrounding portion and supports the bent portion side of the U-shaped fluorescent lamp. The lamp buffer body is formed into a rectangular cylindrical shape having a support side plate and a buffer side plate facing each other, and the support side plate facing the one side wall of the lamp surrounding portion is provided with the U-shaped fluorescent lamp. An engagement hole is provided through which the bent portion side passes, and a cut and a fold are made below the engagement hole of the support side plate so as to extend between the engagement hole and the lower end of the support side plate. A movable piece is provided between the eyes. Further, the lamp buffer body is integrally provided with a spacer protrusion that abuts the inner surface of the other side wall opposite to the one side wall of the lamp enclosure, and the spacer protrusion protects the buffer side plate from the other side wall of the lamp enclosure. The present invention is characterized in that the tip of the bent portion of the U-shaped fluorescent lamp is supported on the inner surface of the buffer side plate at a distance from the side wall.

[Effect]

The packaging container of the packaging device of the present invention accommodates a lighting fixture body into which a U-shaped lamp is previously inserted and connected to a lamp socket fixed to one side wall of a lamp enclosing part. The movable piece of the lamp buffer is folded along the crease to open the lower end into the engagement hole, and then the lamp buffer is housed in the lamp surrounding portion of the lighting fixture housed in the packaging container. When the lamp buffer is housed, the spacer protrusion comes into contact with the inner surface of the other side wall of the lamp surrounding portion opposite to the one side wall, thereby separating the buffer side plate of the lamp buffer from the inner surface of the other side wall. At the same time, the curved portion side of the U-shaped fluorescent lamp is introduced into the engagement hole with its lower end open, and the inner surface of the buffer side plate supports the tip of the curved portion. Thus, the buffer side plate spaced from the inner surface of the lamp enclosure prevents longitudinal movement of the U-shaped fluorescent lamp such that it would become dislodged from the lamp socket. Furthermore, after the lamp buffer is stored, the movable piece is returned to its original position, and the supporting side plate supports the bent side of the U-shaped fluorescent lamp, making it approximately perpendicular to the length direction of the lamp. Prevent movement along the direction that intersects the
