Description

ramp plate

The present invention relates to a transportation aid used for erecting in an environment with a high and low drop; in particular, it refers to a slope board with a supporting structure at its folded position.

In order to avoid some people with long-term mobility impairments due to congenital or acquired damage, persons with limited mobility due to temporary physical factors, or persons with mobility impairments such as people carrying items, they may experience a sudden height drop when using the built environment. Therefore, many building structures are often provided with friendly barrier-free facilities, such as ramps, lifting equipment, wheelchair lifts or ramps. Another example is that some traffic vehicles are also equipped with movable ramps, so that the aforementioned persons with disabilities can get on and off the vehicles smoothly.

It is true that the above-mentioned ramps are erected in an environment with a high and low drop. However, the ramps are heavy and difficult to move and store. For this reason, some manufacturers have improved the ramps to foldable structures to meet the needs of convenient storage when not in use. . However, for the slope board formed by pivoting two or more plates, the mechanical strength of the pivot parts of the plates is weak, and it is easy to form irreversible plastic deformation at the pivot part, so that the slope board cannot be folded again. storage, and even reduce the service life of the ramp. Therefore, the current slope plate is not perfect.

In view of this, the purpose of the present invention is to provide a slope board, which is provided with a reinforcing support structure at the foldable part of the slope board, so as to improve the mechanical strength there.

In order to achieve the above object, the slope board provided by the present invention includes a first board body, a second board body and a pair of supporting frames. Wherein the second board system is pivotally connected with the first board body to be able to move between an unfolded position and a folded position, wherein when the second board body is in the unfolded position, the first board body and the second board body The butt joints of the plates form a continuous slope. When the second plate body is located at the folded position, the first plate body and the second plate body are in a matching state. The pair of support brackets are respectively disposed on the outer side of the pivoting portion of the first plate body and the second plate body, each support bracket includes a first support arm and a second support arm, wherein the first support arms are different The two ends respectively form a first pivot part and a second pivot part, the first pivot part is pivotally connected to the first plate body; the different ends of the second arm respectively form a third pivot part and a support part, the third pivot part is pivotally connected to the second plate body, the second pivot part of the first arm is pivotally connected to the third pivot part of the second arm and the support part between parts.

The effect of the present invention is that when the second board body is in the folded position and the two ends of the ramp board are respectively bearing against the high position and the low position in the environment, the supporting portion of the support frame simultaneously abuts against the low position in the environment , so that the pivoting part of the first plate body and the second plate body is supported by the support frame, and the probability of deformation due to excessive load is reduced.

In order to describe the present invention more clearly, preferred embodiments are given and described in detail with the drawings as follows.
