Abstract

(57) [Summary] (Correction) [Purpose] When a large number of drainage lids are to be installed in series, the lid plates are regularly arranged in parallel at regular intervals. [Structure] Fitting portions 1 having an inverted U-shape are formed facing each other at regular intervals, and inside the outer pieces of the fitting portions 1,
Hemispherical protrusions 4 are formed in each.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fastener used to fix drainage ditch lids in parallel at regular intervals.

[0002]

[Prior art]

 Conventionally, when several drain gutter lids are widely arranged side by side, it is often the case that they are simply connected to each other appropriately by clips, etc. It was not always fixed at intervals and regularly arranged.

[0003]

[Problems to be solved by the device]

 In order to solve such a conventional problem, the present invention is designed such that a large number of drain groove lids are always aligned at regular intervals by using fasteners. It is a thing.

[0004]

[Means for Solving the Problems]

 In order to fit the frame of the peripheral part of the drainage ditch cover, inverted U-shaped fitting parts are formed facing each other at regular intervals, and a hemispherical shape is formed inside the outer piece of each fitting part. A protrusion is formed, and the protrusion has a little flexibility, and the outer piece of the fitting part is slightly opened to open the side surface of the frame at the peripheral edge of the drainage cover fitted to each fitting part. Press to hold and fix.

[0005]

[Action]

 The side surface of the frame at the peripheral edge of the drain groove lid fitted to each fitting portion having an inverted U shape is pressed by the protrusion inside the outer piece of the fitting portion, and the frame is fitted to the fitting portion. The fitting portions, which are fixedly clamped in the inside and fixed to each other by this fixing, are always positioned at a constant interval, and therefore the drain cover is juxtaposed at that position.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the fastener according to the present invention. As shown in FIG. 1, a fixed interval H is provided at the center, and opposite U-shaped fitting portions 1 are formed on opposite sides of the H. Therefore, a hemispherical projection 4 is formed inside the outer piece 2 of each fitting portion 1, and each outer piece 2 is inclined slightly outward so that both sides of its lower end are short. The refraction pieces 3 are respectively formed. Then, when the drain groove lids are connected and continuously provided by such fasteners, the retainer tool of the present invention is provided at an appropriate position on the frame 5 at the peripheral edge of each drain groove adjacent to each other. As described above, that is, the fitting portions 1 are fitted to the frame 5 from above. At this time, the outer piece 2 of the fitting portion 1 is slightly opened and slightly opened. Due to its flexibility, each fitting part 1 can be easily fitted to the frame 5 at the peripheral edge of each adjacent drain groove by pushing the fasteners from above, that is, the upper end of the fitting part 1. After the fitting, each projection 4 strongly presses the side surface of the frame 5 after the fitting, so that the fitted frame 5 is strongly fixed. As shown in FIGS. 1 and 2, the fastening fitting of the present invention has a constant space H between the facing fitting portions, so that the drain grooves are arranged side by side with a gap corresponding to the space H. It is something.

[0007]

[Effect of device]

 According to the present invention having the above-described structure, if the inverted U-shaped fitting portions that are formed facing each other at regular intervals are simply pushed from above into the peripheral frame of the lid of the adjacent drain groove. , Easy to fit and extremely easy to operate, and after fitting, it is fitted by pressing the protrusion inside the outer piece of the fitting part and by the repulsive force of the flexible outer piece. If the drainage lids are regularly arranged side by side at regular intervals after mating, the protrusions are only provided and the operation is also easy. It is expensive.
