Abstract
A foldable bridge platform including a platform, a base bracket with casters installed beneath the bottom thereof, and a vertical rail erected and secured on the base bracket which provides the platform with a guide for adjusting the height thereof. The platform includes at least one main board and two side boards which are pivotally connected to the outer sides of the main board. The main board has a plurality of supporting bulges fixed at the outer sides thereof in order to support the horizontally unfolded side boards. By folding up the side boards of the platform, the width of the bridge platform can be greatly reduced. The foldable bridge platform is thereby convenient for movement and storage.
Description
- The present invention relates in general to a bridge platform, and more particularly, to a foldable bridge platform which is capable of assisting a disabled person when he negotiates stairs or a rugged place.
- Climbing stairs is difficult both for disabled persons who utilize a wheelchair and for other disabled persons with limited mobility. Nonetheless, stairs exist everywhere in human society. To assist the disabled person in traversing stairs, or a concave or rugged place, a bridge platform capable of being adjusted the height thereof is provided.
- A conventional bridge platform has wheels installed beneath the bottom thereof, and therefore, possesses mobility. However, the conventional bridge platform is too wide to pass through a narrower channel while it is being moved inside a building. Moreover, the conventional bridge platform is overly large, and therefore, is inconvenient for storage.
- The present invention provides a foldable bridge platform which adopts a foldable structure in order to decrease the width of the platform for facilitating the movement and storage of the bridge platform.
- The foldable bridge platform provided by the present invention includes a platform, a base bracket with casters installed beneath the bottom thereof, and a vertical rail erected and secured on the base bracket for providing the platform a guidance to adjust the height thereof. The platform includes at least one main board and two side boards which are pivotally connected to the outer sides of the main board. The main board has a plurality of supporting bulges fixed at the outer sides thereof in order to support the horizontally unfolded side boards. By folding up the side boards of the platform, the width of the bridge platform can be greatly reduced and the objective of the present invention is thereby attained.
- These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of preferred embodiments.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.
- These as well as other features of the present invention will become more apparent upon reference to the drawings therein:
-
FIG. 1 is a perspective view of a foldable bridge platform of the present invention stored in a compact condition. -
FIG. 2 is a perspective view of a foldable bridge platform of the present invention with the foldable platform thereof partially opened. -
FIG. 3 is an enlarged view of the portion “A” of the foldable bridge platform ofFIG. 2 . -
FIG. 4 is a partial perspective view of a foldable bridge platform of the present invention with the foldable platform thereof fully unfolded. - Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
- Referring to
FIG. 1 andFIG. 2 , the folded and unfolded configurations of afoldable bridge platform 1 are shown respectively. Thebridge platform 1 is capable of being transported to a place with a height difference for utilization in assisting a disabled person in easily traversing a concave or rugged place. Thebridge platform 1 includes aplatform 10, abase bracket 11, and avertical rail 12. - The
base bracket 11 is mainly utilized to support thevertical rail 12 and keep thevertical rail 12 standing upright. Thebase bracket 11 includes a pair ofelongated side struts 110 which are parallel with each other; a plurality ofcasters 112 installed beneath theside strut 110 for facilitating the movement and orientation of thebridge platform 1; and atransverse strut 111 capable of maintaining the specific distance between the pair ofside struts 110, which is connected to theside struts 110 in order to assemble abase bracket 11. - The
vertical rail 12 is installed in an upright manner onto thebase bracket 11 adjacent to the rear ends of theside struts 110. Thevertical rail 12 facilitates the adjustment of the height of theplatform 10. The specific height of thevertical rail 12 is sufficient for theplatform 10 to adjust the height thereof when providing the bridging function. - Referring to
FIG. 1 throughFIG. 3 , one of the objectives of the present invention is that thebridge platform 1 must be foldable so that thebridge platform 1 can consume less space. Theplatform 10 includes amain board 100; at least twoside boards 101 which are pivotally connected to themain board 100 via one ormore hinges 102; and a plurality of supportingbulges 103 fixed at the outer edges of themain board 100 in order to support theside boards 101 when theplatform 10 is unfolded for use, which also restricts theside boards 101 to being folded upward. Consequently, in order to store or move thebridge platform 1, a consumer merely folds theside boards 101 up to decrease the width of theplatform 10 which facilitates the movement of thebridge platform 1. In contrast, when the consumer moves thebridge platform 1 to a place with height difference in order to install theplatform 10 for utilization by disabled persons, he simply unfolds theside boards 101 which allows theside boards 101 to lie horizontally. The span of theplatform 10 is, thereby, sufficiently extended for disabled persons to traverse a place with height difference. - In addition, two
ramp plates 104 can be attached to the outer sides of theside boards 101. Theramp plate 104 is pivotally connected to theside board 101 through one or more hinges which may have the same structure as that of thehinges 102, as illustrated inFIG. 2 . When theramp plate 104 is unfolded for utilization, the ramp descends from theside board 101 toward the ground. The outer edge of theramp plate 104 will press against the ground. Because of this, a disabled person riding a wheelchair can easily move his wheelchair onto theplatform 10 in order to pass over a rugged place. Furthermore, on the front end of the bridge platform 1 asafety handrail 105 can be added to help prevent the disabled person from inadvertently falling from theplatform 10. Thehandrail 105 also provides assistance to persons with limited mobility while they pass through theplatform 10, and therefore, enhances the usage safety of thebridge platform 1. - While an illustrative and presently preferred embodiment of the invention has been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
