Adaptive ramp for accessing an enclosed ice surface

Abstract

An ice access ramp assembly for accessing an ice surface includes a central bridge section and a pair of ramp sections. Each ramp section is pivotably mounted to the central bridge section for movement between a folded configuration and an extended configuration. The ramp sections and the central bridge section have surfaces formed of a low friction material. When the ramp assembly is extended, a first ramp section provides access from an outer floor and enables a sled skater to move up the first ramp section and onto the central bridge section. The sled skater can then move from the central bridge area onto the second ramp section, which provides access onto the ice surface. When not in use, the ramp assembly can be folded for storage and transport. The ramp assembly may include wheels that facilitate transport of the ice access ramp assembly over a floor or other surface.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of access devices, such as for use by disabled persons, and more particularly to a ramp for providing access to an enclosed ice surface.

2. Background

Sled skating and sled hockey are sports that enable certain persons to enjoy activities on ice that may not otherwise be possible. Sled skating involves a specially designed sled with skate blades under a seat. A person sits on the seat and uses short sticks with ice picks at one end to propel himself or herself across the ice. Sled skating is a noncontact activity that provides an excellent upper body workout to improve core muscles and trunk balance. Sled hockey can be played by sled skaters using the rules of hockey. For sled hockey, the sticks include blades, like the blade of a conventional hockey stick, to move the puck. Often, sled skating and sled hockey are activities enjoyed by persons who may not have full use of their legs, such as those with cerebral palsy, amputations, paraplegia, spina bifida, club feet, hip and knee problems, multiple sclerosis, etc.

Most standard enclosed ice areas or ice surfaces are not conducive for sled skaters because a raised area is located between the ice surface and the outer floor that surrounds it. Typically, the raised area is defined by a lower part of a door frame, which mounts a door that can be opened and closed to provide access to the ice surface. In the past, sled skaters have been moved onto the ice surface from the surrounding floor by one or more persons physically lifting the sled skaters off the floor, transporting them over the raised area and then lowering them onto the ice surface. Sled skaters can be any age and size, and it can readily be appreciated that moving larger sled skaters onto and oft the ice surface can be a daunting task.

What is therefore needed is an easy, convenient way to move sled skaters onto and off an ice surface over a raised area that surrounds the ice surface.

SUMMARY AND OBJECTS OF THE INVENTION

The present invention is designed to provide sled skaters with an easy convenient way to access an ice surface that includes a raised area or step adjacent the edge of the ice surface. In accordance with the present invention, an ice access ramp assembly for accessing an ice surface includes a central bridge section or area and a pair of ramp sections located one on either side of the central bridge area. Each ramp section is pivotably mounted at an inner end to the central bridge area such that the ramp sections can be moved between a folded configuration and an extended configuration. The ramp sections and the central bridge area have surfaces formed of a low friction material. When the ramp sections are in the extended configuration, a first one of the ramp sections provides access from an outer floor and enables a sled skater to be move up the first ramp section and onto the central bridge area. The sled skater can move from the central bridge area onto a second one of the ramp sections, which provides access onto the ice surface. Such movements are reversed when the sled skater wishes to move off the ice surface onto the surrounding floor. When not in use, the ramp sections can be placed in the folded configuration for storage and transport. The ramp sections may include wheels that facilitate transport of the ice access ramp assembly over a floor or other surface.

Various other features, objects and advantages of the present invention will be made apparent from the following description taken together with the drawings.

DETAILED DESCRIPTION

The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.

Referring to FIG. 1, an ice access ramp assembly 10 in accordance with the present invention is illustrated in an extended, use position. Ice access ramp assembly 10 generally includes a central bridge section 12, a first ramp section 14 located on one side of the bridge section 12, and a second ramp section 16 located on the other side of bridge section 12.

In the illustrated embodiment, bridge section 12 includes a pair of spaced apart transverse upright frame members 18 and a series of upper frame members, such as shown at 20, that are located between transverse upright frame members 18. Bridge section 12 further includes an upper wall or panel 22 that overlies the frame members 18, 20.

First and second ramp sections 14, 16, respectively, have the same general construction. First ramp section 14 has a frame assembly 24 constructed of a series of interconnected frame members, along with an upper wall or panel 26 that overlies frame assembly 24. Similarly, second ramp section 16 has a frame assembly 28 constructed of a series of interconnected frame members, along with an upper wall or panel 30 that overlies frame assembly 28. The inner end of frame assembly 24 of first ramp section 14 is pivotably connected to bridge section 12 adjacent one of transverse upright frame members 18, such as via a conventional piano-type hinge assembly. Similarly, the inner end of frame assembly 28 of second ramp section 16 is pivotably connected to bridge section 12 adjacent the other of transverse upright frame members 18, such as via a conventional piano-type hinge assembly. The frame members at the outer ends of frame assemblies 24, 28 may be beveled so as to enable the outer ends of respective top panels 26, 32 to be close to the surface on which the outer ends of the respective ramp sections 14, 16 are supported.

The upper surface of panel 22 of bridge section 12, as well as the upper surfaces of panels 26, 30 of respective ramp sections 14, 16, are formed of a material having a low coefficient of friction. Representatively, the panels 22, 26 and 30 may be formed of a Lexan material or other such low friction material. Representative satisfactory materials for panels 22, 26 and 30, commonly known as synthetic ice, are available under the designations Easy Glide from coldproducts.com and Super Glide from syntheticiceusa.com, although it is understood that any other satisfactory low friction material may be employed.

Wheel assemblies or casters, shown at 32, are mounted to the outer frame members of frame assemblies 24, 28.

FIG. 2 illustrates ice access ramp assembly 10 in a folded, non-use configuration such as for transport or storage. In this position, the first and second ramp sections 14, 16, respectively, are folded about their respective hinges at bridge section 12, and the outer ends of ramp sections 14, 16 are moved toward each other. The beveled outer ends of the frame members of frame assemblies 24, 28 enable the outer ends of the ramp sections 14, 16 to be moved close together. A retainer mechanism, such as shown in FIG. 3 as a pair of releasable hooks 34, may be employed to releasably maintain ice access ramp assembly 10 in the folded configuration. When not in use, the hooks 34 may be engaged with conventional eyes 36 secured to frame members of the frame assemblies 24, 28. Casters 32 facilitate movement of ice access ramp assembly 10 when in the folded, non-use configuration.

FIGS. 4 and 5 illustrate the ice access ramp assembly 10 of the present invention in use, for facilitating movement of a sled skater, shown at SS, onto and off an ice surface I over a step S. In this application, ice access ramp assembly 10 is initially unfolded to its extended, use configuration and then positioned such that bridge section 12 overlies step S. In this position, ramp section 14 extends over the ice surface IS and its outer end is supported by the ice surface I. Similarly, the ramp section 16 extends over the floor outside the step S and the ice surface I, and its outer end is supported by the floor.

As shown in FIG. 4, the panels, such as 22, 26 and 30 are provided with gripper strips 38 at their outer edge areas. The gripper strips 38 are formed of a material that can be relatively easily penetrated by the picks at the ends of the sticks used by the sled skater SS. In this manner, the sled skater can approach the end of ramp section 14 under his or her own power, and then move the sled onto the upper surface of panel 26 over the slight rise at its end defined by the thickness of panel 26. Alternatively, to eliminate the slight rise, the end of panel 26 may be beveled. The sled skater SS can then use his or her own sticks to engage the strips 38 and move himself or herself up the ramp section 14 on the panel 26, onto the panel 22 of the bridge section 12, and then onto the panel 30 of the ramp section 16 for movement onto the surrounding floor. Alternatively, if desired, a helper or two may be positioned adjacent the ice access ramp assembly 10 to provide assistance to the sled skater SS along the ramp surfaces. When use of the ice access ramp assembly 10 is completed, it is lifted off the ice surface I, step S and surrounding floor and then folded for transport or storage.

It can thus be appreciated that the ice access ramp assembly of the present invention provides quick and easy movement of sled skaters from a floor onto an ice surface over a step that surrounds the ice surface. The ice access ramp assembly can be compactly folded for storage, and is easily moved from one location to another.
