Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a groove cover which is covered on the upper surface of a side groove.

[0002]

2. Description of the Related Art Conventionally, a groove cover is provided on the upper surface of a side gutter. However, when a vehicle, a person, or the like passes over the groove cover, the vehicle easily slips and a slip accident or the like easily occurs.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a groove cover free from a slip accident or the like. Provided are two or more upper surface members having a U-shaped cross section with an opened upper surface and an elastic material fitted to each of the upper surface members, and the upper surface material has a folded piece folded inward from an upper end portion. A fitting recess is formed between the lower end and the bottom of the elastic member, and a flange piece that fits into the fitting recess protrudes from a lower side surface of the elastic member, and a protrusion for preventing slippage protrudes from an upper surface. That is.

[0004]

An elastic material is fitted on the upper surface of the groove cover, which has a U-shaped cross section, and a ridge for preventing slippage is formed on the upper surface of the elastic material. Thus, a slip accident can be prevented. Further, the elastic member can be attached to the upper surface member by fitting the flange piece into the fitting concave portion of the upper surface member to prevent the elastic member from being pulled out.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic partial cross-sectional perspective view of a groove cover, and FIG. 2 is a cross-sectional view thereof.

The groove cover 1 has a plurality of upper surface members 2, 2, 2 arranged in parallel on the upper surface thereof, and the longitudinal ends of the upper surface members 2, 2 are welded to the side frame plate 4, for example. It is fixed by means. Latching plates 5 and 5 having an L-shaped cross section are provided on both sides along the longitudinal direction on the side surfaces in the width direction, and the lower surfaces of the upper members 2 and 2 are orthogonal to the lower surfaces. The reinforcing plates 6 and 6 are disposed at predetermined intervals in a shape, and the reinforcing plates 6 and 6 are
2 is fixed by means such as welding. Further, the tip portions of the retaining plate 5 and the reinforcing plate 6 are also fixed by means such as welding.

Each of the upper surface members 2 is made of a metal such as an iron material, is formed in a U-shaped cross section with an open upper surface, and is formed in a rising shape on both sides of a bottom piece 2a. , 2b are formed, and folded pieces 2c, 2c folded inward from the upper ends of the rising pieces 2b, 2b are integrally formed. Fitting recesses 2d, 2d are formed at the bottom between the lower ends of the folded pieces 2c, 2c and the upper surface of the bottom piece 2a.

An elastic member 3 is fitted to each upper surface member 2 from the upper side. The elastic member 3 is formed of a material such as rubber, and is fitted over the entire length of each upper surface member 2. Is what is done. The elastic member 3 is formed with ridges 3a, 3a, 3a projecting upward at predetermined intervals and extending in the longitudinal direction on the upper surface side thereof, and grooves 3b, 3a, 3a, 3a are provided between the ridges 3a.
3b is formed along the longitudinal direction.

[0009] Also, from the back side of the elastic material 3 upward, 2
Inside grooves 3d, 3d are formed, and flange pieces 3c, 3c are integrally formed at the lower end of the elastic member 3 so as to protrude laterally. Since the elastic member 3 has elasticity, the elastic member 3 can be fitted inside the upper surface member 2 from above, and at this time, the flange pieces 3c, 3c of the elastic member 3 are fitted with the fitting recesses 2d, 2c.
d, and the elastic member 3 is properly prevented from being pulled out of the upper surface member 2.

In the fitted state, the ridges 3a, 3a, 3a of the elastic member 3 project further above the upper end of the rising piece 2b of the upper surface member 2, so that as shown in FIG. When the groove cover 1 is covered on the upper surface of the side groove 10, the groove cover 1
When a car or a person passes over the ridges 3a,
3a, 3a are stepped on, and the ridges 3a, 3a, 3
a prevents slippage satisfactorily and provides a groove lid with less slippage.

Further, the elastic member 3 can be deformed through the inner grooves 3d by the pressing force from the upper side, so that the elastic member 3 has a cushioning property and exhibits a cushioning function when it falls down. And reduce the occurrence of injuries. Further, the strength of the upper surface member 2 is increased by the folded pieces 2c, 2c, the strength is extremely large against an impact force or the like from above, and the strength of the entire groove cover 1 is sufficiently secured. .
Also, the groove cover 1 can be satisfactorily covered on the upper surface of the side groove 10 by being suitably hooked on the inner surface of the upper end of the side groove 10 by the locking plate 5.

[0012]

The groove cover according to the present invention includes two or more upper surface members having a U-shaped cross section and having upper surfaces opened at predetermined intervals, and elastic members fitted to the respective upper surface members. The upper surface member has a fitting recess formed between a lower end and a bottom portion of a folded piece folded inside from an upper end portion, and the elastic member has a flange piece fitted into the fitting recess on a lower side surface. Is formed on the upper surface, and the upper surface is formed with a folded piece to increase the strength against impact force, pressing force, etc. from above, Moreover, it is possible to prevent the detachment of the elastic member by properly fitting the flange piece of the elastic member into the fitting recess, and to effectively prevent a slip accident or the like by the ridge on the upper surface of the elastic member.
