Description

[Detailed description of the invention] The present invention relates to a gutter and lid engagement structure for reliably and removably attaching the lid to the housing opening, and in particular,
This invention relates to a gutter and lid engagement structure in which the upper lid of a pachinko ball supply gutter can be attached and removed in a bar-like manner.

Gutters used as ball supply channels in pachinko halls are generally equipped with lids to prevent dust. However, if the lid of these pachinko ball flow gutter is fixed with screws etc., it will not be possible to open and close quickly when balls become clogged, and if the lid is simply placed on the gutter opening, balls will be scattered in the gutter. Not only does the lid tend to come off, but there is also the problem of not being able to sufficiently muffle the sound of the balls passing inside and the sound of the flow.

The present invention has been devised to solve these problems, and provides a lid fastening device that has a simple structure and can reliably and removably attach the lid to the housing opening.

The present invention basically consists of forming pairs of slits or openings near the left and right edges of the lid to be engaged with the opening edges of the casing, and connecting both ends of a spring member having a restoring function to the left and right edges. The above object is achieved by a lid engaging device which is removably inserted into the slit of the housing to engage the edge of the casing between the edge of the lid and the spring member.

Hereinafter, the most preferred embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a housing to which the lid fastening device of the present invention is applied, and the figure illustrates a gutter for feeding pachinko balls. The gutter 1 has a concave passageway through which pachinko balls flow, and edges 1b, 1b projecting inward are formed at the tips of the left and right side walls 1a, 1a.

Reference numeral 2 denotes a lid for closing the opening between the end edges 1b, 1b of the gutter 1, and the lid body 2 steps the left and right end edges 2a, 2a corresponding to the end edges 1b, 1b of the gutter 1. It is formed into a step shape through the portions 2b, 2b, and
Preferably, slits or openings 3a, 3 parallel to the plate surface of the lid body 2 are provided at the rising bases of the left and right step portions 2b, 2b.
b... are bored in pairs on the left and right.

Reference numeral 4 designates a leaf spring whose both ends are fitted between the slits 3, 3 of the lid 2 to engage the lid 2 with the housing 1. The leaf spring 4 has a curved portion 4a in the center, and can be attached and removed between the slits 3a, 3a of the lid 2 by utilizing the bending of the curved portion 4a and its restoring force.
The shape of the leaf spring 4 is not limited to that of the illustrated embodiment, but may be any other shape as long as it can be attached to and removed from the slit by a restoring action.

Thus, when the lid 2 is attached to the gutter 1 using the device of the present invention, the stepped edges 2a, 2a of the lid 2 are nested in the edges 1b, 1b of the gutter 1, as shown in FIGS. 2 and 3. At the same time, the leaf spring 4 is deflected, and its restoring force pulls both ends of the leaf spring 4 through the slit 3.
a, 3a or 3b, 3b. The edge 2a of the lid 2 that engages with the upper surface of the gutter edge 1b is formed in a step shape, and the slits 3a, 3b, . . . are provided at the rising bases of the left and right steps. The tip of is fitted under the edge 1b of the gutter 1. Therefore, vertical movement of the lid 2 is locked. When removing the lid 2, by pulling the central curved portion of the leaf spring 4 upward, the lid spring will come off due to deflection and the lid can be easily unlocked.

Since the present invention has the above structure, it is possible to securely connect the gutter and the lid with a simple structure, and especially when used as a pachinko ball supply gutter, there is no risk of the lid coming off due to scattering of balls inside the gutter. It disappears.

Particularly, in the present invention, the lid can be opened by sliding the lid from side to side with respect to the gutter while keeping the leaf spring engaged. Moreover, since the leaf spring functions as a sliding handle at this time, the sliding operation becomes easy.

In addition, although the above explanation has mainly been about the case where the present invention is applied to the gutter of the pachinko ball supply route,
The present invention is not limited to this, but can be widely applied to lid attachment of a housing having an opening.

Claims (1)

[Scope of utility model registration request] The opening edge of the casing constituting the gutter is made to protrude inward, and the left and right edges of the lid are formed into a stepped shape rising from the plate surface of the lid main body, and the plate surface of the lid is formed at the base of the raised part of the step. A gutter and lid engagement structure characterized in that a pair of slits or openings are bored in parallel to the slits or openings, and both ends of a leaf spring having a curved or bent part in the middle are fitted into the pair of slits or openings.
