ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a chain cover for a pedal exerciser, more particularly to a chain cover including a casing body having a front casing part and a rear casing part that can be assembled easily to the front casing part.
2. Description of the Related Art
In a conventional chain cover for an exercise pedal assembly, a casing body includes a front casing part with a rear opening, and a rear casing part that is connected detachably to the front casing part to close the rear opening. However, the rear casing part is difficult to assemble onto the front casing part due to the lack of guiding means on the adjoining edges of the front and rear casing parts.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a chain cover for an exercise pedal assembly including a casing body with front and rear casing parts that can be easily and quickly assembled together.
According to the present invention, the chain cover for an exercise pedal assembly comprises a casing body having a front casing part with a rear opening, and a rear casing part that is connected detachably to the front casing part to close the rear opening. The front casing part has a first top wall, a bottom wall and two opposing first side walls interconnecting the first top wall and the bottom wall. The first top wall has a first top end. The first side walls have opposing first side ends which extend downwardly from the first top end. The bottom wall has a U-shaped first bottom end with two opposing portions which extend respectively and rearwardly from the first side ends and which merge with one another after turning toward one another. The rear opening is defined by the first top end, the first side ends and the first bottom end. The rear casing part has a second top wall, two opposing second side walls extending downwardly from the second top wall, and a rear wall connected to the second top wall and the second side walls. The second top wall has a second top end opposite to the rear wall. The second side walls have opposing second side ends that extend downwardly from the second top end. The second side walls and the rear wall cooperatively form a U-shaped second bottom end. The U-shaped second bottom end has two opposing portions which extend respectively and rearwardly from the second side ends to the rear wall. The first and second side ends extend straightaway in a downward direction. The first top wall and the first side walls are provided with first rail members. The second top wall and the second side walls are provided with second rail members. The first and second rail members on the first and second top walls are interlocked with one another to prevent the rear casing part from disengaging rearwardly from the front casing part when the front and rear casing parts are connected to one another. The first and second rail members on the first and second side walls interconnect slidably the first and second side ends and permit the second side ends to slide over the first side ends in a downward direction from the first top end when the front and rear casing parts are connected to one another.
