TEMPORARY RAIL ASSEMBLY

Abstract

The invention describes a device that enables people with special needs (SEN), namely with mobility impairment of the lower limbs, to access the sea from the beach, without assistance from another person. According to the present invention, independent access is achieved by using a portable, rail-type mechanism which can be assembled easily on the beach. The rail operates as a stable track for a carriage to be drawn along. The starting point of the track is at a distance from the shoreline, in a place with wheelchair access. The end of the track is in the water at an appropriate point where the water's depth is sufficient for the disabled user to swim without problems.

Description

The invention describes a device that enables people with special needs, namely with mobility impairment of the lower limbs, to access the sea from the beach, without assistance from another person.

[sentences rearranged in the paragraph below for better ‘flow’]

People with mobility impairments have equal rights with other citizens to enjoy social benefits. One such right is access to beaches. Swimming is very beneficial to their physical health, while being able to participate in activities from which they were hitherto excluded is also beneficial to their mental health. What is needed is a device that will allow them enter the sea on their own.

Such a device will take the mobility-impaired person from a point on the beach with wheelchair access to a point in the sea where they can swim safely. When they have finished swimming, the device would then transport them back to the waiting wheelchair. At the same time, the device should not denature permanent the natural environment of the beach.

Until now, the ability of the mobility-impaired person to swim in the sea has depended on the help of others. The disabled person had to be lifted manually from the wheelchair and carried into the sea to a sufficient depth where he or she could move in the water without further assistance.

A part from the above method, a structure has been tested which includes a dock that extends out from the beach, a short distance above the sea. At the end of the dock, a small crane is installed to lower the disabled person into the sea. Because the structure is permanently installed, its main disadvantage is that it alters the physical environment and aesthetics of the landscape. The foundation of this structure, whether constructed of concrete or steel is a permanent intervention on the beach. In addition, it is difficult for such a platform to extend far enough into the sea to ensure adequate depth at the point of user entry to protect the user from potential accidents. Finally, the use of a crane for lowering the user into the water increases the likelihood of injury while the user is suspended in the air. Another solution has been tested, involving the construction of a cement ramp which allows disabled people to roll their wheelchairs into the sea. In this case, the disadvantage of permanent intervention in the natural environment persists. It is also very difficult for the user to leave the sea, forcing the mobility-impaired person to seek help from others and, thus, losing the advantage of independent access. Moreover, taking the wheelchair into seawater can lead to corrosion of both the metal and textile parts, rendering the chair unusable after a few uses.

Existing solutions assist the disabled to have access to the sea, but they have a number of disadvantages that make them difficult to apply. A solution is needed which will overcome the disadvantages of the existing structures and which would not require permanent alteration of the beach area. Such a solution should give the user complete independence, eliminate the need for a supportive companion, preserve the structural integrity of the wheelchair, and pose no risk of injury to the user.

According to the present invention, these requirements are achieved by using a portable, rail-type mechanism which can be assembled easily on the beach. The rail will operate as a stable track for a carriage to be drawn along. The starting point of the track will be at a distance from the shoreline, in a place with wheelchair access. The end of the track will be in the water at an appropriate point where the water's depth is sufficient for the disabled user to swim without problems.

Such a device, according to the present invention, has several advantages. The track may be disassembled into parts small enough to be easily transported. It can be used for access to the sea, to lakes and even to rivers. Its placement in the selected area would not require the construction of permanent bases and anchorages that would affect the natural environment. The device is temporary in nature and, after each use, can be dismantled and moved to a storage area, while the area of its use is restored its original condition. The end (sea) position of the track can be placed at the desired water depth. In addition, the user operates the control system and can stop the movement of the carriage at any point desired, before the predetermined end of the route. The starting (land) point of the track is far enough from the water that the wheelchair is not at risk of getting wet and, consequently, damaged. The point where the user boards the carriage need not be the starting point of the track. The user can select, via the control system, to move the platform away from the starting point of the track. This option enables the device to be used simultaneously by more than one user. If the first user boards the carriage at the starting point of the track, the second user should place his wheelchair a short distance down the track from the starting point, next to the wheelchair of the first. The seat on the carriage is at such a height above the ground to make it easy for the user to move from the wheelchair to the carriage and provides sufficient support to the user so as to be protected from injury. The carriage is moved along the track by an electric motor. To meet the motor's energy needs, it is possible to connect the device to the power grid or to use renewable energy. Materials with high resistance to corrosion are used for the construction of the invention.

The invention is described below with the help of an example shown in the attached FIGURE, in which:

FIG. 1 is a perspective view of an assembled portable swimming access device for people with mobility impairment. This figure shows the track assembly (2) along which the carriage (1) moves. The carriage (1) in FIG. 1 shows a chair mounted on a suitable moving mechanism. Alternatively, according to the position in which the user chooses to be moved, the chair could be replaced by a bed-like carriage, allowing the user to be transported in a more reclining position, or by a stool without back support. The carriage (1) is moved by a drive mechanism (4), which in this view is at the end of the device outside the water. Alternatively, the drive mechanism could be located at the other end or attached to the carriage (1). In the example in FIG. 1, the drive mechanism (4) operates with power from a photovoltaic panel (10), while wind may also be used as a source of energy or the device can receive the required energy directly from the power grid. Movement is controlled by the user, via commands processed by the electronic control unit which in the example in FIG. 1 is in position (7). At the ends of the route (5) and (6) defined by the track (2), there are sensors that stop the carriage (1) when approaching the ends (5) and (6). These sensors are magnetic or electrical or mechanical. At the end of the track in the water (5), handrails (8) provide the user with support if needed when getting on and off the carriage.

The non-fixed assembled device allows the disabled swimmer access to water in the sea, a lake, a river or a pool. The device can be used simultaneously by more than one user and can serve users with different types of disabilities such as paraplegia, quadriplegia, multiple sclerosis, neuro-muscular dystrophy, Parkinson's, various conditions stemming from bone deformities and various ambulatory problems.
