BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide assembly combined with stair.
2. Description of the Prior Arts
Slide is a common entertainment facility. The conventional slide has a climbing section, a platform, and a sliding section. The conventional slide can be made of rocks, metal or plastic. The slide made of rocks or metal is stable and durable, so the slide made of rocks or metal is often placed in a park or a playground for the public. The slide made of plastic is light and is easy to transport, so the size of the plastic slide is reduced and is placed in an indoor playground for the children. However, the conventional plastic slide occupies the indoor space and is placed on the ground by its weight, so the conventional plastic slide is not firmly fixed on the ground. Children are exposed to risks when playing on the plastic slide.
To overcome the shortcomings, the present invention provides a clamped slide assembly to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a clamped slide assembly to be combined with an open riser stair and is firmly mounted on the open riser stair to achieve the goal of saving indoor space and improving stability.
The clamped slide assembly comprises a slide, a main body, at least one inner clamping panel, and a clamping unit. The slide has a platform and a sliding section, and the sliding section is connected to the platform. The main body is securely mounted on a bottom of the platform of the slide and has an adjusting screw hole. The at least one inner clamping panel is securely mounted on the platform of the slide or the main body and each one of the at least one inner clamping panel extends downward. The clamping unit is movably mounted on the main body and has an outer clamping panel, a screwing rod, and a spanner. The outer clamping panel is spaced apart from the at least one inner clamping panel. An inner end of the screwing rod is screwed with the adjusting screw hole of the main body. The screwing rod is mounted through the outer clamping panel and an outer end of the screwing rod extends out of the outer clamping panel. The spanner is rotatably and eccentrically mounted on the outer end of the screwing rod, and the outer clamping panel is pushed towards the main body and the at least one inner clamping panel by rotating the spanner.
The clamped slide assembly in accordance with the present invention is applied to an open riser stair. A depth of the screwing rod screwed with the adjusting screw hole is adjusted according to a width of each one of the treads of the open-riser stair to decide a distance between the outer clamping panel and the main body. After finishing the width adjustment, the main body is put on a top surface of one of the treads of the open riser stair, the at least one inner clamping panel abuts on a back surface of the tread, and the outer clamping panel abuts on a front surface of the tread opposite to the at least one inner clamping panel. The spanner is rotated to pull the screwing rod and to push the outer clamping panel, so the outer clamping panel and the inner clamping panel tightly clamp the tread, and the clamped slide assembly can be securely fastened on the open riser stair to achieve the goal of saving space.
