Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side gutter having a U-shaped open-sided upper wall with lid-hanging portions formed on upper portions of both side walls. 2. Description of the Related Art A drainage channel, a wireway, and the like for draining rainwater are formed by continuously laying side grooves with a lid. FIG. 6 is an end view of a conventional side groove with a lid, and shows two side walls 2 of a side groove main body 1.
The lid 4 is supported on a lid holder 3 having a step formed at the upper part of the a and 2b. If both sides of the lower surface of the lid 4 are not supported in conformity with the steps of the lid holder 3, the lid 4 supported by the lid holder 3
When a vehicle or the like passes over the vehicle, the lid 4 is unequally supported by the lid holder 3 and swings to generate rattling and noise. Then, in order to prevent the generation of noise, there has been proposed a device in which a rubber plate is integrated with the step portion of the lid hanging portion 3. [0004] However, in the case where the rubber plate is integrated with the stepped portion of the lid holder, although the vertical vibrations are absorbed, when the vehicle passes in the lateral direction, In many cases, noise is generated because the door moves to the adjacent lid and collides with the adjacent lid. In addition, the rubber deteriorates with time and emits noise. In addition, the rubber plate must be integrated with the step of the lid hook, making the production complicated and
There is also a problem that it takes time and costs. Accordingly, the present invention is to provide a gutter with a lid which can reduce the generation of noise. According to the present invention, there is provided a gutter cover for covering a gutter body having a lid hooking portion formed on upper portions of both sides of a U-shape having an open upper portion. is supported by the cover hooking portions on both sides of the wall, to form a ridge in the longitudinal direction on the lower surface of the lid, trapezoidal engagement is thereby formed on both end surfaces of the inclined surfaces parallel to the vertical direction of the lid, on one end face A mating convex portion is formed, and a trapezoidal engaging concave portion is formed on the other end surface, into which the engaging convex portion of the adjacent lid enters and engages. FIG. 1 is a longitudinal sectional view in the width direction of a gutter according to the present invention, FIG. 2 (a) is a side view of a gutter main body, and FIG. 2 (b) is a front view thereof. In FIG. 1, a vertical section of a side groove main body 1 is formed in a U-shape with an open upper part, and walls 2 on both sides are formed.
On top of a and 2b, a lid hanging portion 3 having a step is formed. In FIG. 1, the lid support surface 3a for supporting the lid 4 is formed as an inclined surface, but may be formed as a horizontal plane or an arc. In addition, a sealing material 2c made of rubber or the like may be provided on the end surface of the side groove main body 1 in order to improve the adhesiveness between the adjacent side groove main bodies 1. Further, as shown in FIG. 2, an engagement convex portion 1a and an engagement concave portion 1b are formed on an end face of the side groove main body 1 in order to facilitate positioning of connection with the adjacent side groove main body 1. In the center, there is a hook hooking hole 1c for lifting or hanging the gutter main body 1. FIG. 3 is a view showing the back surface of the lid of the gutter according to the present invention. In FIG. 3, a lid 4 to be placed on the upper part of the gutter main body 1
On the lower surface on both sides supported by the lid hook of the gutter body,
A downwardly extending ridge 5 is formed in each of the longitudinal directions.
Due to the ridges 5 of the lid 4, the ridges 5 of the lid 4 are supported by the lines on the lid support surface 3 a of the lid holder 3 and are self-aligned, so that there is no play in the vertical direction. FIGS. 4A and 4B show an embodiment of the lid, wherein FIG. 4A is a plan view, and FIG. 4B is a sectional view taken along line AA of FIG. The lid 4 is continuously arranged on a lid hook formed on the upper side of the walls 2a and 2b of the gutter main body. Lid 4
In the first embodiment, an inclined surface 6 parallel to the vertical direction is formed on each end face of the side groove main body 1 in the longitudinal direction. Further, on each end surface, an engagement projection 7 for positioning the adjacent lid 4 and an engagement recess 8 into which the engagement projection 7 of the adjacent lid 4 enters and engages are formed. By making the end surface of the lid an inclined surface 6, the end surfaces of the adjacent lids overlap each other, and when the vehicle passes, the lid 4 is closed.
Is not displaced in the longitudinal direction of the side groove main body 1 and does not collide with each other, so that noise can be reduced. In addition, by forming the engaging convex portion 7 and the engaging concave portion 8, the movement in the width direction can be reduced. And the collision between the lid 4 and the side groove main body 1 can be reduced. 5A and 5B show another embodiment of the lid, wherein FIG. 5A is a plan view, FIG. 5B is a cross-sectional view taken along line BB of FIG. 5A, and the same components as those in FIG. The description is omitted. The present embodiment differs from the cover shown in FIG. 3 in that the engaging projections 7 and the engaging recesses 8 of the cover 4 are alternately formed in two rows. By forming the engagement protrusions 7 and the engagement recesses 8 in two rows, the movement of the side groove main body 1 in the width direction can be restricted, so that the generation of noise can be reduced. According to the present invention, since the lid is supported by a line on the lid supporting surface of the lid holder and is self-aligned by forming a ridge on the lower surface of the lid, By eliminating the backlash and making the end surfaces of the lids inclined surfaces, the end surfaces of the adjacent lids are displaced in the longitudinal direction of the side groove main body and do not collide with each other, so that noise can be reduced. Further, by forming the engaging projection and the engaging recess on the end surface of the lid, the movement in the width direction can be reduced, and the collision between the lid and the side groove main body can be reduced, thereby further reducing the generation of noise. Can be done.
