Description

[Detailed description of the invention] The present invention relates to a mechanism for attaching and detaching the lid of a reel storage case, and in particular, an attaching and detaching mechanism that has a small number of parts, makes it extremely easy to attach and detach the lid, and securely locks the lid to the main body. This is what we are trying to provide.

An embodiment of the present invention will be described with reference to the drawings. In the figure, 1 is the lid of the reel storage case, and 2 is the center portion of the lid that is glued to this lid. The central part 2 of the lid consists of an annular part 2' and a handle part 2'' that crosses the center of this annular part. Reference numeral 3 is a push button mounted in a hole in the handle part 2'' so as to be movable up and down. Its lower end 3' is bent outward to prevent it from coming off the handle 2''. Reference numeral 4 denotes a pair of engagement plates horizontally provided on the lid 1.
It is rotatable around a vertical pin 5 formed in the
A concave engaging portion 4' is provided on the opposite side.
Further, the engagement plate 4 is formed with a protrusion 4 having an inclined surface 4''. Reference numerals 6 and 7 are stoppers integrally formed on the lid 1, and limit the rotation of the engagement plate 4 around the pin 5. Reference numeral 8 indicates a reel. The main body of the storage case 8' is a central part glued to the main body 8. A vertical mushroom-shaped locking member 9 is formed in this central part to engage with the concave engaging part 4'. This is a spring that urges the push button 3 upward.

Next, the operation of the attachment/detachment mechanism having the above structure will be explained. When a reel (not shown) is stored in the main body 8 and the lid 1 is closed, first, the concave engaging portion 4' of the engaging plate 4
is pressed against the mushroom-shaped locking member 9 and the engaging plate 4 rotates around the pin 5, so that the concave engaging portion 4' expands and slides down on the slope 9' of the locking member 9. It engages with the locking member 9. This locks the lid 1 to the main body 8 (see FIG. 5).

To open the lid 1, hold the handle 2'' and press the push button 3 with your finger.
slides downward on the slope 4'' of the protrusion 4, the engagement plate 4 rotates around the pin 5, and its concave engagement portion 4' expands (see Fig. 6).In this state, the lid 1 is opened. When lifted, the engaging portion 4' is disengaged from the locking member 9, and the lid 1 opens.

As shown in the figure, the movement of the engagement plate 4 is restricted at one end by a stopper 6, so that when the push button 3 is pressed, it bends elastically as shown in FIG. When the push button is released, the engagement plate returns to the state shown in FIG. 5 due to its elastic force. At this time, the push button is lifted by the elastic force of the engagement plate 4, so the spring 10 is not necessarily required. In this way, in the above embodiment, in order to engage the engaging portion 4' and the locking member 9 and to lift the push button 3, the engaging plate 4 is
Although the elastic force of the engagement plate 4 is utilized, instead, for example, tension springs may be attached to both ends of the engagement plate 4 on the stopper 6 side.

As described above, in the present invention, a mushroom-shaped locking member is provided on the reel storage case main body side, a pair of engagement plates are provided horizontally on the reel storage case lid side, and this engagement plate is attached to the opposite side of the locking member. The engaging plate is provided with a concave engaging portion capable of engaging with the member and is rotatable around a vertical pin, and the engaging plate is biased in a direction in which the engaging portion engages with the locking member, and further An engagement operation member for rotating the engagement plate around the pin in a direction to release the engagement between the engagement part and the locking member is provided on the reel storage case lid side, so the attachment/detachment mechanism can be used in 5 types of 4 types. It can be composed of parts. Therefore, the attachment/detachment mechanism according to the present invention has a simple structure and is inexpensive to manufacture. Further, simply by closing the lid, the lid is locked to the main body, and the lid can be opened by releasing this locking with one hand. Therefore, it is extremely easy to attach and detach the lid.
