1. Field of the Invention
This invention relates to a canopy, and in particular, it relates to a height adjustment structure for a canopy.
2. Description of the Related Art
Canopies are useful for outdoor activities as a sun or rain shelter. For example, it may provide a place for resting and dining at outdoor parties, or provide a place for resting when camping, etc. Existing canopies are typically made up of framework and a cover. To make it convenient for carrying and storing, the framework can be disassembled and re-assembled when needed. The framework may be disassembled when the canopy is not in use for convenient carrying and storing. Even so, there are still some shortcomings in existing canopies. Under different circumstances or at different times, users may have different requirements for the height of the canopy. For example, due to change of the direction of the sun, proper adjustment may be required in the height of the canopy, but the height of existing canopies depend on the height of the vertical poles in the framework and cannot be adjusted. Adjustment of the height requires changing the height of the vertical poles.
Accordingly, the present invention is directed to a height adjustment structure for a canopy that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
The present invention solves the above technical problem by providing a simple height adjustment structure of the canopy that is convenient to use.
To solve the above technical problem, a height adjustment structure for a canopy is provided, which includes: a vertical pole having a plurality of holes defined thereon; a sliding sleeve disposed around the vertical pole and having connecting parts formed thereon, the sliding sleeve having a through hole defined on a sidewall thereof; and a spring loaded press plate pivotally mounted on the sidewall of the sleeve and having a locking pin at one end. The sliding sleeve is slideable along the vertical pole to align the through hole with one of the holes on the vertical pole, and the locking pin of the press plate is capable of extending through the through hole of the sleeve and a hole on the vertical pole aligned with the through hole, thereby locking the sleeve at a desired height.
In another aspect, the present invention provides a framework for a canopy incorporating the above height adjustment structure.
Because holes are provided along the pole, when the sliding sleeve slides up and down to a certain location along the pole, the locking pin pressing against the surface of the pole will fall into the hole to lock the sliding sleeve. The sliding sleeve may be connected with the roof frame of the canopy and the height of the roof may be changed by adjusting the location of the sliding sleeve on the pole. The height adjustment structure has a simple structure that used the cooperation between the locking pin and the holes on the pole to lock the sliding sleeve to the pole. In addition, the use of a press plate structure and lever action makes it easy to use.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
As shown in
Connecting parts are formed on the sleeve 20 to connect it with other components of the canopy. In the illustrated example, the connecting parts are a pair of plates 23, 24 with through holes.
In addition, several holes 11 are formed along the pole 1. When the sliding sleeve 2 slides up and down to proper locations along the pole 1, the through hole on the sleeve is aligned with one of the holes 11 on the pole 1, and the locking pin 211 pressed against the surface of the pole 1 will fall into the hole 11 to lock the sliding sleeve 2 relative to the pole 1.
The spring loaded press plate 21 may be designed to have various shapes as required, two examples of which are shown in
It will be apparent to those skilled in the art that various modification and variations can be made in the height adjustment structure for a canopy of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
