A spine extends transversely to the ramp elements, the spine comprising a spine body having a lower surface, the lower surface of the spine body comprising a grip pad. The first and second ramp elements are provided on opposing longitudinal sides of the spine and are pivotable from an unfolded use position in which the ramp elements both extend downwardly from the spine to a folded storage position in which the ramp elements both extend upwardly from the spine. The first ramp element is pivotally connected to the spine and pivotable about a first axis of rotation and the second ramp element is pivotally connected to the spine and pivotable about a second axis of rotation, the first and second axes of rotation being horizontally spaced either side of an axis of the spine. In the folded storage position, the ramp surfaces face one another.

Description

RAMP
Technical Field
The present disclosure relates to ramps for facilitating movement between two positions separated by an obstruction such as a door threshold. In particular, the present disclosure relates to a threshold ramp and to a foldable bridge ramp.
Background
It is known to provide bridge ramps to facilitate access e.g. for people in wheel chairs, people with mobility impairments, or people pushing pushchairs/prams, into buildings having an obstruction such as a door threshold at the entrance. The bridge ramp can bridge the obstruction where the two ground levels either side of the obstruction may be the same or different from one another.
Some bridge ramps are foldable to facilitate storage and/or transport. Foldable bridge ramps usually comprise two opposing ramp elements each connected by a hinge either to each other or to an interposed central platform/spine. In some known foldable bridge ramps, legs are provided on the underside of each ramp element adjacent the hinge(s). The hinges allow the bridge ramp to be folded when the bridge ramp is not in use e.g. when the bridge ramp is transported or stored. These bridge ramps are folded with their ramp surfaces (i.e. the upwards facing surfaces over which a user travels during use) facing outwards so that any legs are contained within/between the folded ramp elements.
To bring these known foldable bridge ramps from their folded transport/storage configuration to their unfolded use configuration, a user must generally pivot the ramp elements about the hinge into their unfolded configuration (whilst resting the bridge ramp on its side or on one of the ramp surfaces) and then manoeuvre the unfolded bridge ramp into position over the obstacle with the adjustable legs resting either side of the obstacle. This makes these bridge ramps cumbersome and difficult to deploy for use. Similarly, removing the known foldable bridge ramps after use also requires manoeuvring of the bridge ramp in its unfolded configuration prior to folding.
I
Some known foldable bridge ramps (that fold with their ramp surfaces facing outwards) have two opposing ramp elements which meet at a hinged ridge. Such a ridge (which extends perpendicularly to the direction of travel of a user over the ramp surfaces) can present a beaching risk for wheel chairs/pushchairs i.e. the wheel chair/push chair may become stuck with its wheels either side of the hinged ridge.
As an aside, it is also known to provide ramps to facilitate access into building from a lower ground level to a higher ground level e.g. where one or more steps is/are provided at the entrance. Such ramps are sometimes foldable. Such ramps cannot bridge an obstacle such as a door threshold and thus are not considered to be "bridge ramps".
It is a preferred aim of the present invention to provide an improved threshold ramp e.g. an improved foldable bridge ramp.
Summary
Accordingly, in a first aspect, there is provided a foldable bridge ramp, the bridge ramp comprising: a first ramp element having a first ramp surface; a second ramp element having a second ramp surface; and a spine extending transversely to the ramp elements, wherein the first and second ramp elements are provided on opposing longitudinal sides of the spine and are pivotable from an unfolded use position in which the ramp elements both extend downwardly from the spine to a folded storage position in which the ramp elements both extend upwardly from the spine; and wherein, in the folded storage position, the ramp surfaces face one another.
By providing a foldable bridge ramp where the ramp surfaces face one another when in the storage configuration, the bridge ramp can be more easily unfolded from its storage configuration to its use configuration. The user can position the spine over the obstruction e.g. over the door threshold with the ramp elements in their folded configuration i.e. extending upwardly from the spine. The ramp elements can then be lowered downwards into their use configuration. Similarly, after use, the bridge ramp can be left in position with the spine overlying the obstruction and the ramp elements can be raised upwards into their folded configuration. This avoids the user having to manoeuvre the bridge ramp whilst in its unfolded configuration.
Furthermore, by folding the ramp elements upwards into the closed position such that the ramp surfaces face one another, transfer of dirt/debris deposited on the ramp surface to the person folding the bridge ramp is avoided. In addition, the ramp surfaces are often textured or abrasive and, as such, are known to snag the user's clothing during manoeuvring the ramp. By folding the ramp elements with the ramp surfaces facing each other, damage to the user's clothing by the abrasive ramp surfaces can be avoided.
Optional features will now be set out. These are applicable singly or in any combination with any aspect.
The term 'ramp surface' as used herein is intended to refer to the surface of each ramp element which is uppermost during use i.e. the surface which faces away from the ground during use and over which a user travels during use. Conversely, a 'lower surface' of each ramp element is the surface which is lowermost in use i.e. the surface which faces the ground during use.
Each ramp element and each ramp surface will have a proximal edge proximal the spine and a distal edge distal the spine. In use (when the bridge ramp is in its unfolded configuration), the user will travel between the proximal and distal edges of the ramp elements/surfaces. For example, a user will cross the distal edge of the first ramp element/surface to mount the bridge ramp, the proximal edges of the first and then the second ramp elements/surfaces to cross the spine and then the distal edge of the second ramp element/surface to leave the bridge ramp.
The proximal and distal edges of the first and second ramp elements/surfaces each extend parallel to the axis and longitudinal sides of the transverse spine.
In the unfolded, use configuration, the distal edges are positioned vertically lower than the proximal edges (and spine) such that the first and second ramp elements both extend downwardly from the spine. The distal edges may be horizontally aligned with each other (where the ground is of substantially equal height either side of the obstruction) or vertically spaced from each other (where the ground is of unequal height either side of the obstruction).
In the folded configuration, the distal edges are positioned vertically higher than the proximal edges (and spine) e.g. they may be positioned directly, vertically above the spine. The distal edges of the first and second ramp elements/surfaces may be in contact with each other in the folded configuration.
The first ramp element and the second ramp element may both be pivotally connected to the spine. They may each be pivotable through an angle greater than 90 degrees between the folded position and the unfolded position, e.g. the first ramp element and the second ramp element may each be pivotable through an angle of greater than 100 degree, such as greater than 110 degrees. They may both be pivotable by about 120 degrees between the folded position and the unfolded position.
The first and/or second ramp surface may comprise a textured grip surface. It/they may comprise a rubberised surface, for example, it/they may comprise a rubberised coating on the ramp surface of the first/second ramp element(s). The first and/or second ramp surface may comprise a textured grip surface comprising grit particles.
The first ramp element and/or the second ramp element may (each) be a single, unitary planar sheet of material e.g. a metal sheet such as an aluminium sheet. Accordingly, each ramp element may comprise a single, unitary planar sheet (e.g. metal/aluminium sheet) with a textured, (e.g. rubberised and/or gritted) ramp surface.
The spine extends transversely between its first and second axial ends in a direction perpendicular to the direction of travel of the user over the ramp surfaces/elements. The axis of the spine is parallel to the distal and proximal edges of the ramp surfaces/elements.
The spine may comprise a spine body which may be substantially cylindrical or tubular. It may have a quadrilateral (e.g. a rectangular, square or trapezoid) cross-section (perpendicular to the axis of the spine). The spine body may comprise an upper wall and a lower wall (which may be parallel to the upper wall) each extending between the axial ends of the spine and spaced by longitudinal side walls. The longitudinal side walls may join the upper wall along first and second upper longitudinal edges.
The lower wall may have a greater width (perpendicular to the spine axis) than the upper wall. For example, the spine body may have a trapezoid cross-section (perpendicular to the axis of the spine).
Additionally/alternatively, the lower wall may extend beyond the longitudinal side walls in a width wise direction (i.e. in a direction perpendicular to the axis of the spine).
The lower wall may provide a lower surface of the spine. The upper wall may provide an upper surface of the spine.
The lower surface of the spine may be configured to rest upon the obstruction. It may comprise a gripping or cushioning element (e.g. a grip or cushion pad) having a contact surface for contacting/overlying the obstruction. The grip pad may be elongate and may extend at least partly along the length of the lower surface of the spine. The contact surface of the grip pad may comprise a series of elongate ridges (aligned with the axis of the spine).
The elongate grip pad may comprise a gap extending between the longitudinal sides of the spine (e.g. a central gap at the longitudinal centre of the lower surface of the spine) for enabling the lower surface of the spine to span a raised portion of the obstruction on which the contact surface rests, e.g. a raised lock plate on a door threshold.
The grip pad may be made of a resilient e.g. rubber material. It may be formed by extrusion or moulding, for example.
The grip pad has an upper surface opposite the contact surface. The upper surface may have a recess e.g. defined by upstanding longitudinal edges for receiving and gripping the longitudinal side walls of the spine body.
The contact surface preferably has a greater width (perpendicular to the axis of the grip pad (and spine)) than the opposing upper surface. Thus the upper surface and contact surface of the grip pad may be spaced by inclined longitudinal side walls so that the cross section of the grip pad (perpendicular to the axis of the element/spine) splays from the upper surface to the contact surface. The contact surface preferably has a greater width (perpendicular to the axis of the grip pad (and spine)) than the upper wall of the spine body.
The spine may comprise a respective bumper element at one or both of its opposing axial ends. The/each bumper element may extend longitudinally (in the direction of the spine axis) beyond the ramp surfaces/elements. This protects the doorframe from damage by the ramp. The/each bumper element may have an insertion portion for insertion into the respective axial end of the spine in order to secure the bumper element to the spine.
The/each bumper element may be formed of a plastic material. It/they are preferably formed of a non-marking material so that there is no transfer of material to the doorframe. The/each bumper element may be either compressible or rigid.
The first and/or second ramp elements may each comprise at least one cut out extending transversely to provide a portion having a smaller width in the transverse direction of the ramp elements (i.e. in a direction parallel to the axis of the spine) than a remainder of the first/second ramp elements. The/each ramp element may comprise two opposing, transversely-extending cut outs. The/each cut out may be provided proximal the spine e.g. adjacent the proximal edge(s) of the ramp element(s). The cut out(s) can help protect the doorframe from damage by the ramp.
Preferably, the first ramp element is pivotally connected to the spine and is pivotable (between the folded and unfolded configuration) about a first axis of rotation.
Preferably, the second ramp element is pivotally connected to the spine and is pivotable (between the folded and unfolded configuration) about a second axis of rotation.
The first and second axes of rotation each extend parallel to the axis of the spine and the distal/proximal edges of the ramp element/surfaces.
The first and second axes of rotation may be horizontally spaced either side of the axis of the transverse spine. The horizontal spacing between the first and second axes of rotation may be less than the width of the lower wall of the spine body (the width being transverse to the axis of the spine) and/or less than the width of the contact surface of the grip pad. This helps reduce rolling of the spine on the obstruction during use.
For example, the first and second axes of rotation may extend along the first and second upper longitudinal edges of the spine body respectively. In this case, the spine body may have a trapezoid cross-section (perpendicular to the axis of the spine) with a wider lower wall (than upper wall) or the spine body may have a lower wall that extends beyond the longitudinal side walls in the width direction or the grip pad may have a contact surface wider that its upper surface (and wider that the upper wall of the spine body).
In other embodiments, the first axis of rotation may overlie the upper wall/surface of the spine body, located inwards from the first longitudinal side wall of the spine body (i.e. towards the spine axis). The second axis of rotation may overlie the upper surface of the spine body, located inwards from the opposing second longitudinal side wall of the spine body.
In some embodiments, the first ramp element is connected to the spine e.g. to the upper wall/surface of the spine or to the first upper longitudinal edge of the spine body by one or more first hinges. The first hinge may simply comprise a flexible strip of material extending between and connected to the proximal edge of the first ramp element and the first upper longitudinal edge of the spine. In other embodiments, the or each first hinge may comprise a first ramp element hinge portion (connected to the proximal edge of the first ramp element) and a first spine hinge portion (connected to the spine portion). The first ramp element hinge portion(s) and first spine hinge portion(s) will be pivotable relative to each other about the first axis of rotation. The first hinge may be a double hinge with two first axes of rotation.
In some embodiments, the second ramp element is connected to the spine e.g. to the upper wall/surface of the spine or to a second upper longitudinal edge of the spine body by one or more second hinges. The second hinge may simply comprise a flexible strip of material extending between and connected to the proximal edge of the second ramp element and the second upper longitudinal edge of the spine. In other embodiments, the or each second hinge may comprise a second ramp element hinge portion (connected to the proximal edge of the second ramp element) and a second spine hinge portion (connected to the spine portion). The second ramp element hinge portion(s) and second spine hinge portion(s) will be pivotable relative to each other about the second axis of rotation. The second hinge may be a double hinge with two second axes of rotation.
The first spine hinge portion(s) may be affixed to the first longitudinal side wall of the spine body. The second spine hinge portion(s) may be affixed to the second longitudinal side wall of the spine body.
The first ramp element hinge portion(s) may be affixed to the lower surface of the first ramp element. The second ramp element hinge portion(s) may be affixed to the lower surface of the second ramp element.
For example, the first hinge(s) may be butt hinges with the first leaf of the/each butt hinge joined to the first ramp element (e.g. the lower surface of the first ramp element) and the second leaf of the/each butt hinge joined to the spine (e.g. the first longitudinal side wall of the spine). The second hinge(s) may be butt hinges with the first leaf of the/each butt hinge joined to the second ramp element (e.g. the lower surface of the second ramp element) and the second leaf of the/each butt hinge joined to the spine (e.g. the opposing second longitudinal side wall of the spine body). The knuckles of the first butt hinge(s) (and thus the first axis of rotation) may be along the first upper longitudinal edge of the spine. The knuckles of the second butt hinge(s) (and thus the second axis of rotation) may be along the second upper longitudinal edge (opposite the first upper longitudinal edge) of the spine.
In other embodiments, the first spine hinge portion(s) may be affixed to the upper surface/wall of the spine body. The second spine hinge portion(s) may be affixed to the upper surface/wall of the spine body.
The first ramp element hinge portion(s) may extend from the proximal edge of the first ramp element. The second ramp element hinge portion(s) may extend from the proximal edge of the second ramp element.
For example, the/each first hinge may comprise a first hinge barrel mounted on/above the upper wall/upper surface of the spine body or on the proximal edge of the first ramp element and a first hinge pin mounted on the other of the upper wall/upper surface of the spine or on the proximal edge of the first ramp element. Similarly, the/each second hinge may comprise a second hinge barrel mounted on the upper wall/upper surface of the spine body or on the proximal edge of the second ramp element and a second hinge pin mounted on the other of the upper wall/upper surface of the spine body or on the proximal edge of the second ramp element.
In some embodiments, the first spine hinge portion(s) may (each) comprise a first hinge barrel (extending in the direction of the spine axis) which may be mounted on/above the upper surface/wall of the spine body. The second spine hinge portion(s) may (each) comprise a second hinge barrel which may be mounted on/above the upper surface/wall of the spine body.
The first ramp element hinge portion(s) may (each) comprise a first pin which may extend along the proximal edge of the first ramp element. The second ramp element hinge portion(s) may (each) comprise a second pin which may extend along the proximal edge of the second ramp element.
The hinge pins are received in the hinge barrels to pivot around the respective axis of rotation.
In some embodiments, the first spine hinge portion (e.g. the first hinge barrel(s)) may form part of a first connector element which is mounted e.g. pivotally mounted on the upper surface/upper wall of the spine body. The second spine hinge portion (e.g. the second hinge barrel(s)) may form part of a second connector element which is mounted e.g. pivotally mounted on the upper surface/upper wall of the spine body.
The first connector element may further comprise a further first hinge barrel. The second connector element may further comprise a further second hinge barrel.
The further first hinge barrel may be pivotably mounted on a first spine hinge pin and the further second hinge barrel may be pivotably mounted on a second spine hinge pin, each spine hinge pin upstanding from the upper wall/surface of the spine and extending transversely (parallel to the axis of the spine).
In this way, the first/second ramp elements can be pivoted about a double hinge between the folded and unfolded configurations by pivoting of the first/second ramp hinge pin(s) within the first/second hinge barrel(s) and pivoting of the further first/second hinge barrel about the first/second spine hinge pin.
The spine body and spine hinge pins may be unitary e.g. they may be formed as a single extrusion. The connector element may be extruded.
The first and/or second ramp elements may include a covering plate disposed at one or both opposing axial ends of the first and/or second hinges (e.g. at opposing axial ends of the first/second spine hinge pins and/or at opposing axial ends of the first/second hinge barrels) to help prevent dirt/debris entering the first and/or second hinges.
In the unfolded use configuration, the bridge ramp may comprise a central portion that is substantially horizontal or that extends downwardly from the spine at an angle less than the ramp surface. Providing such a central portion on the bridge ramp can prevent low ground clearance mobility devices travelling over the bridge ramp from beaching on the bridge ramp.
The central portion may be interposed between the first ramp element/surface and the second ramp element/surface. The central portion may be between the first axis of rotation and the second axis of rotation.
The upper wall/upper surface of the spine may form at least part of the central portion. For example, in embodiments where the first axis of rotation is along the first upper longitudinal edge of the spine (e.g. a rectangular, square or trapezoid cross-section spine) and the second axis of rotation is along an opposing second upper longitudinal edge of the spine, the upper surface of the spine may form at least part of the central portion.
In some embodiments, the first and second connector elements may form at least part of the central portion. For example, outer surfaces of the further first and second hinge barrels (i.e. the surfaces not in contact with the spine pins) may form the central portion. The outer surfaces of the further first and second hinge barrels may comprise longitudinally extending ribs (i.e. ribs parallel to the axis of the spine).
The first and/or second ramp elements/surfaces may form at least part of the central portion. Thus, the first and/or second ramp elements surfaces may each comprise a proximal portion (proximal the proximal edge and the spine) which is substantially horizontal in use and a distal inclined portion (i.e. a portion that is angled downwardly from the spine at a greater angle than the proximal portion in the unfolded configuration).
The cut outs described above will be provided in the proximal portion(s) of the ramp elements.
The proximal portions of the ramp elements may be integral with the ramp hinge pins. They may be secured to the inclined portions e.g. using connectors such as rivets, bolts or screws.
In the folded configuration, the ramp elements (e.g. the distal portions of the ramp elements) may be parallel one another. They may abut one another. The central portion described above and/or the horizontal spacing of the axis of rotation facilitates the alignment/abutment of the ramp elements in the folded configuration.
The first and/or second ramp elements may comprise at least one strengthening rib. The strengthening rib may extend across the lower surface of the first/second ramp element. The first and/or second ramp elements may each comprise two or more strengthening ribs transversely spaced across the lower surface of the ramp elements.
The first and/or second ramp elements may comprise a handle. The handle may be at or towards the first distal edge. The handle(s) may comprise a cut-out in the first/second ramp element.
The first and/or second ramp elements may comprise a resilient lip element disposed at the distal edge. The lip element(s) can help retain the bridge ramp in position during use in the unfolded use configuration. The lip element(s) may include a lower surface which, in use, may rest on a surface (e.g. the ground) and an upper surface which may be angled so as to match the inclination of the first ramp surface/the second ramp surface. The upper surface of the lip element(s) may comprise ridges (e.g. transversely extending ridges) to prevent slippage of a user or a mobility device as it travels over the lip element. The lip element(s) may be as described in GB patent no. 2419867.
In a second aspect, there is provided a threshold ramp comprising: a first ramp element having a first ramp surface; a second ramp element having a second ramp surface; a spine extending transversely to the ramp elements; and a respective bumper element at one or both of the opposing axial ends of the spine, wherein the first and second ramp elements are provided on opposing longitudinal sides of the spine; and wherein the/each bumper element extends beyond the ramp elements in the direction of the spine axis.
By providing a threshold ramp having a spine with a bumper element(s) at its axial end(s), the doorframe surrounding the threshold may be protected from damage by the ramp.
The/each bumper element may have an insertion portion for insertion into the respective axial end of the spine in order to secure the bumper element to the spine.
The/each bumper element may be formed of a plastic material. It/they are preferably formed of a non-marking material so that there is no transfer of material to the doorframe. The/each bumper element may be either compressible or rigid.
The first and/or second ramp elements may each comprise at least one cut out extending transversely to provide a portion having a smaller width in the transverse direction of the ramp elements (i.e. in a direction parallel to the axis of the spine) than a remainder of the first/second ramp elements. The/each ramp element may comprise two opposing, transversely-extending cut outs. The/each cut out may be provided proximal the spine e.g. adjacent the proximal edge(s) of the ramp element(s). The cut out(s) can help protect the doorframe from damage by the ramp.
The first and/or second ramp surface may comprise a textured grip surface. It/they may comprise a rubberised surface, for example, it/they may comprise a rubberised coating on the ramp surface of the first/second ramp element(s). The first and/or second ramp surface may comprise a textured grip surface comprising grit particles.
The first ramp element and/or the second ramp element may (each) be a single, unitary planar sheet of material e.g. a metal sheet such as an aluminium sheet. Accordingly, each ramp element may comprise a single, unitary planar sheet (e.g. metal/aluminium sheet) with a textured, (e.g. rubberised and/or gritted) ramp surface.
The spine may be as described above for the first aspect. The lower surface of the spine may be accommodated in a grip pad as described above for the first aspect.
The first and/or second ramp elements may comprise at least one strengthening rib as described for the first aspect.
The first and/or second ramp elements may comprise a handle as described for the first aspect.
The first and/or second ramp elements may comprise a resilient lip element as described for the first aspect.
The ramp elements and/or ramp surfaces may be as described above for the first aspect.
In some embodiments, the threshold ramp is a foldable bridge ramp, wherein the first and second ramp elements are pivotable from an unfolded use position in which the ramp elements both extend downwardly from the spine to a folded storage position in which the ramp elements both extend upwardly from the spine.
The first ramp element and the second ramp element may both be pivotally connected to the spine. They may each be pivotable through an angle greater than 90 degrees between the folded position and the unfolded position, e.g. the first ramp element and the second ramp element may each be pivotable through an angle of greater than 100 degree, such as greater than 110 degrees. They may both be pivotable by about 120 degrees between the folded position and the unfolded position.
Preferably, the first ramp element is pivotally connected to the spine and is pivotable (between the folded and unfolded configuration) about a first axis of rotation.
Preferably, the second ramp element is pivotally connected to the spine and is pivotable (between the folded and unfolded configuration) about a second axis of rotation.
The first and second axes of rotation may be as described for the first aspect.
In some embodiments, in the folded storage position, the ramp surfaces face one another as described for the first aspect.
In some embodiments, the first ramp element is connected to the spine e.g. to the upper wall/surface of the spine or to the first upper longitudinal edge of the spine body by one or more first hinges. The first hinge may be as described for the first aspect.
In some embodiments, the second ramp element is connected to the spine e.g. to the upper wall/surface of the spine or to a second upper longitudinal edge of the spine body by one or more second hinges. The second hinge may be as described for the first aspect.
The first and/or second ramp elements may include a covering plate as described for the first aspect.
In the unfolded use configuration, the bridge ramp may comprise a central portion as described for the first aspect.

Detailed Description of the Embodiments
Fig 1 shows an embodiment of a foldable bridge ramp 100 in an unfolded use configuration. The bridge ramp 100 indudes a first ramp element 102 with a first ramp surface 104 and a second ramp element 106 with a second ramp surface 108, the ramp elements 102, 106 being provided on opposing longitudinal sides of a transversely extending spine 110. The first 102 and second 106 ramp elements are each a single unitary planar sheet of metal with rubberised and textured first 104 and second 108 ramp surfaces. The first 102 and second 106 ramp elements each comprise a proximal edge 112a, 112b proximal the spine 110 and a distal edge 114a, 114b distal the spine 110.
In the unfolded configuration, the distal edges 114a, 114b are vertically lower than the proximal edges 112a, 112b such that the first 102 and second 106 ramp elements extend downwardly from the spine 110. The first 102 and second 106 ramp elements each comprise a handle 116a, 116b towards the distal edges 114a, 114b. The handles 116a, 116b comprise an aperture in the first/second ramp elements 102, 106.
The first 102 and second 106 ramp elements are both pivotally connected to the spine 110 and are each pivotable by 120 degrees between their unfolded position and their folded position (shown in Fig 5 and described further below).

The lower wall 120 extends beyond the longitudinal side walls 122a, 122b in a width wise direction. The spine 110 comprises a first bumper element 124a at the axial end of the spine body 110. The bumper element 124a extends longitudinally beyond the spine 110 and beyond the ramp surfaces 104, 108. The spine 110 also comprises a second bumper element 124b at the other axial end of the spine 110 (not shown in Fig 2) which also extends longitudinally beyond the spine 110 and ramp surfaces 104, 108. These bumper elements which are formed of non-marking, rigid plastic prevent damage to the doorframe when manoeuvring the ramp in and out of position.
The upper wall 118 provides an upper surface of the spine 110 and the lower wall 120 provides a lower surface of the spine 110. The lower surface 120 of the spine 110 is configured to rest upon an obstruction (e.g. a door threshold) and comprises a grip or cushion pad 126 made of rubber material and having a contact surface 128 for contacting the obstruction. As best shown in Fig 5, the grip/cushion pad 126 extends along the length of the lower surface 120 of the spine body 110 and comprises a central gap 130 at the longitudinal centre of the lower surface of the spine 110 for enabling the lower surface 120 of the spine 110 to span a raised portion of the obstruction on which the contact surface 128 rests e.g. a raised lock plate on a door threshold.
Fig 3 shows a side view of the bridge ramp 100. The spine body 110 is substantially tubular with a rectangular transverse cross-section. The first ramp element 102 is pivotally connected to the upper wall/surface 118 of the spine body 110 by a first hinge 132a and is pivotable about a first axis of rotation 134a. The second ramp element 106 is pivotally connected to the upper wall/surface 118 of the spine body 110 by a second hinge 132b and is pivotable about a second axis of rotation 134b. The first 134a and second 134b axes of rotation each extend parallel to the axis of the spine body 110 and are horizontally spaced either side of the axis of the spine body 110. The horizontal spacing between the first 134a and second axis 134b of rotation is less than the width of the lower wall 120 of the spine body 110.
As shown by Fig 3, the first axis of rotation 134a overlies the upper wall/surface 118 of the spine body 110 and is located inwards from the first longitudinal side wall 122a of the spine body 110. The second axis of rotation 134b overlies the upper wall/surface 118 of the spine body 110 and is located inwards from the opposing second longitudinal side wall 122b of the spine body 110.
Fig 4 shows a detailed view of the first 132a and second 132b hinges. The first hinge 132a comprises a first spine hinge portion 136a connected to the upper wall/surface 118 of the spine body 110 and a first ramp element hinge portion 138a connected to the proximal edge 112a of the first ramp element 102. The second hinge 132b comprises a second spine hinge portion 136b connected to the upper wall/surface of the spine body 110 and a second ramp element hinge portion 138b connected to the proximal edge of the second ramp element 106.
The first spine hinge portion 136a comprises a first spine hinge pin 140a upstanding from the upper wall/surface 118 of the spine body 110 and extending transversely (parallel to the axis of the spine). The first spine hinge portion 136a also comprises a first connector element 137a comprising a first hinge barrel 142a pivotally mounted on the upper wall/surface of the spine body 110.
The first ramp element hinge portion 138a comprises a first ramp pin 144a which extends along the proximal edge 112a of the first ramp element 102 and which is received in the first hinge barrel 142a of the first connector element, such that the first ramp pin 144a and the first hinge barrel 142a pivot relative to each other about the first axis of rotation 134a.
The first connector element 137a also comprises a further first hinge barrel 146a pivotally mounted on the first spine hinge pin 140a. Thus, by pivoting the first ramp pin 144a within the first hinge barrel 142a and pivoting the further first hinge barrel 146a about the first spine hinge pin 140a, the first ramp element 102 is pivoted about a double hinge.
The second spine hinge portion 136b comprises a second spine hinge pin 140b upstanding from the upper wall/surface 118 of the spine body 110 and extending transversely (parallel to the axis of the spine). The second spine hinge portion 136b also comprises a second connector element 137b comprising a second hinge barrel 142b pivotally mounted on the upper wall/surface of the spine body 110.
The second ramp element hinge portion 138b comprises a second ramp pin 144b which extends along the proximal edge of the second ramp element 106 and which is received in the second hinge barrel 142b of the second connector element, such that the second ramp pin 144b and the second hinge barrel 142b pivot relative to each other about the second axis of rotation 134b.
The second connector element 137b also comprises a further second hinge barrel 146b pivotally mounted on the second spine hinge pin 140b. Thus, by pivoting the second ramp pin 144b within the second hinge barrel 142b and pivoting the further second hinge barrel 146b about the second spine hinge pin 140b, the second ramp element 106 is pivoted about a double hinge.
The spine body 110 and spine hinge pins 140a, 140b are unitary e.g. they may be formed as a single extrusion. The connector elements 137a, 137b are extruded. Outer surfaces of the further first 146a and further second 146b hinge barrels comprise longitudinally extending ribs 148.
Turning back to Fig 3, the bridge ramp 110 comprises a central portion 150 that is substantially horizontal, i.e. an overall/major plane of the central portion is substantially horizontal/flat. The central portion 150 is interposed between the first ramp surface 104 and second ramp surface 108 and is between the first axis of rotation 134a and the second axis of rotation 134b. The outer surfaces of the further first 146a and further second 146b hinge barrels form part of the central portion 150.
As shown in Fig 3, the first 102 and second 106 ramp elements each comprise a proximal portion 152a, 152b which is substantially horizontal and a distal inclined portion 154a, 154b which is angled downwardly from the spine body 110 at a greater angle than the proximal portions 152a, 152b. The proximal portions 152a, 152b are secured to the distal inclined portions 154a, 154b using bolts/screws 156a, 156b.
Fig 5 shows the bridge ramp 100 in a folded configuration. The first 102 and second 106 ramp elements are shown in their folded storage positions with their distal edges 114a, 114b positioned directly vertically above the spine body 110. In the folded configuration, the distal portions 154a, 154b are parallel to one another and the ramp surfaces 104, 108 face and abut one another. As shown in Fig 5, the central portion 150 and the horizontal spacing between the first 134a and second 134b axes of rotation facilitates abutment of the ramp elements 102, 106 in the folded configuration. As shown in Fig 5, the proximal portions 152a, 152b have a narrower width than the distal inclined portions 154a, 154b provided by cut outs extending transversely from opposing sides of the first 102 and second 106 ramp elements adjacent the proximal edges. These cut outs (along with the bumper elements 124a, 124b) can help protect the doorframe from damage by the ramp.
The first ramp element 102 comprises two strengthening ribs 158a, 158b which extend across the lower surface 105 of the first ramp element 102. The strengthening ribs 158a, 158b are transversely spaced across the lower surface 105 of the first ramp element 102. Although not visible in Fig 5, the second ramp element 106 will also include two strengthening ribs extending across the lower surface of the second ramp element.
Fig 6 shows a detailed view of the spine and the first 132a and second 136b hinges when the bridge ramp 100 is in the folded configuration. As described above, the first ramp pin 144a is pivotable within the first hinge barrel 142a and the further first hinge barrel 146a is pivotable about the first spine hinge pin 140a. In this way, the first ramp element 102 is pivotable about a double hinge between the unfolded position and the folded position. The second ramp pin 144b is pivotable within the second hinge barrel 142b and the further second hinge barrel 146b is pivotable about the second spine hinge pin 140b. In this way, the second ramp element 106 is pivotable about a double hinge between the unfolded position and the folded position.
Fig 7 shows a detailed view of the bridge ramp 100. In this embodiment, the contact surface 128 of the grip/cushion pad 126 comprises a series of elongate ridges 127. The contact surface 128 of the grip/cushion pad 126 has a greater width (in a direction perpendicular to the axis of the spine) than an upper surface of the grip pad 126 such that the grip pad 126 splays outwardly towards the contact surface. The upper surface of the pad 126 comprises a recess in which the lower wall 120 of the spine body is received.
The first 102 and second 106 ramp elements comprise a covering plate 160 disposed at the axial ends of the first 132a and second 132b hinges. In particular, the covering plate 160 is disposed at opposing axial ends of the first/second spine hinge pins 140a, 140b and the further first/second hinge barrels 146a, 146b to prevent dirt/debris from entering them. Although not shown in Fig 7, a covering plate is also disposed at the opposing axial ends of the first 132a and second 132b hinges.
Fig 8 shows a detailed view of the bridge ramp 100, in particular, the distal edge 114a of the first ramp element 102. The first ramp element 102 comprises a resilient lip element 162a disposed at the distal edge 114a of the first ramp element 102. The second ramp element 108 also includes a resilient lip element 162b disposed at the distal edge 114b of the second ramp element 106 (not shown in Fig 8). The lip elements 162a, 162b help retain the bridge ramp 100 in position during use in the unfolded use configuration. The lip elements 162a, 162b include a lower surface which, in use, rests on the ground and an upper surface which is angled so as to match the inclination of the ramp surfaces 104, 108. The upper surface of the lip elements 162a, 162b comprises transversely extending ridges 164 to prevent slippage of a user or mobility device traveling over the lip elements 162a, 162b.
Figs 9 to 12 illustrate another embodiment of bridge ramp 200. This embodiment includes many of the same features of the embodiment described above and shown in Figs 1-8 and, for that reason, corresponding reference numerals have been used albeit with a unit increase of the first digit to represent the further embodiment. A description of the features that are the same will not be repeated here.
Turning first to Fig 9, the spine comprises a spine body 210 which is tubular and has a trapezoid cross-section. The spine body 210 comprises an upper wall 218 and a lower wall 220 spaced by longitudinal side walls 222a, 222b, where the lower wall 220 has a greater width (perpendicular to the spine axis) than the upper wall 218. The longitudinal side walls 222a, 222b join the upper wall 218 along first 224a and second 224b upper longitudinal edges. In this embodiment, the first 234a and second 234b axes of rotation extend along the first 224a and second 224b upper longitudinal edges of the spine body 210 respectively. Due to the trapezoid cross-sectional shape of the spine body 210, the first 234a and second 234b axes of rotation are horizontally spaced either side of the axis of the spine body 210 and the horizontal spacing between the first 234a and second 234b axes of rotation is less than the width of the lower wall 220 of the spine body 210. In this embodiment, the upper wall/surface 218 of the spine body 210 forms part of the horizontal central portion 250.
Referring to Fig 10, this shows a top view of the bridge ramp of Fig 9. The first ramp element 202 is connected to the spine body 210 by first butt hinges 232a. The second ramp element 206 is connected to the spine body 210 by second butt hinges 232b. The connection of the butt hinges 232a, 232b to the spine body 210 and the ramp elements is best shown in Fig 12 and is described below. The knuckles 240a of the first butt hinges 232a (and thus the first axis of rotation 234a) is along the first upper longitudinal edge 224a of the spine body 210 and the knuckles 240b of the second butt hinges 232b (and thus the second axis of rotation 234b) is along the second upper longitudinal edge 224b of the spine body 210. The first 202 and second 206 ramp elements comprise cut outs 262a, 262b at the proximal edges 212a, 212b to help protect the doorframe from damage.
Fig 11 shows the bridge ramp 200 in the folded configuration. The ramp elements 202, 206 are parallel to one another and abut one another when in their folded positions. The central portion 250 and the horizontal spacing of the first 234a and second 234b axes of rotation facilitate abutment of the ramp elements 202, 206 in the folded configuration.
Fig 12 shows a side perspective view of the bridge ramp 200. As described above, the first ramp element 202 is connected to the spine body 210 by first butt hinges 232a. The first leaf 236a of each butt hinge is joined to a lower surface 205 of the first ramp element 202 and the second leaf 238b of each butt hinge 232a is joined to the first longitudinal side wall 222a of the spine body 210. Similarly (although not visible in Fig 12), the second ramp element 206 is connected to the spine body 210 by second butt hinges 232b. The first leaf 236b of each butt hinge is joined to the lower surface 207 of the second ramp element 206 and the second leaf 238b of each butt hinge 232b is joined to the opposing second longitudinal side wall 222b of the spine body 210 Figs 13a-13f illustrate the sequence of steps performed by a user when opening the bridge ramp 100/200 from its folded storage/transport configuration to its unfolded use configuration. Referring first to Figs 13a-13c, the user positions the bridge ramp 100/200 over the obstruction, in this case a door threshold. The user can use the handles to lift and place the bridge ramp 100/200 in position. The user positions the bridge ramp 100/200 by resting the lower surface 120/220 of the spine body 110/210 on the door threshold. Turning to Figs 13d-13e, once the lower surface 120/220 of the spine body 110/210 is resting on the door threshold, the user lowers the first ramp element 102/202 by pivoting it about the first axis of rotation 134a/234a, until the distal edge 114a/214a rests on the ground on a first side of the door threshold. The user then lowers the second ramp element 106/206 by pivoting it about the second axis of rotation 134b/234b, until the distal edge 114b/214b rests on the ground on the opposite side of the door threshold. Fig 131 shows the bridge ramp 100/200 in the unfolded use configuration already positioned over the obstruction and ready for use without the user needing to manoeuvre the bridge ramp 100/200 whilst in its unfolded configuration. After use, the user can raise the ramp elements 102/202, 106/206 back into their folded positions (by pivoting them about their axes of rotation) whilst leaving the bridge ramp 100/200 in position with the spine body 110/210 resting on the door threshold. The bridge ramp 100/200 can be brought from its unfolded use configuration to its folded storage/transport configuration without the user having to manoeuvre the bridge ramp 100/200 whilst in its unfolded configuration. The steps described in relation to Figs 13a-13f are applicable to all embodiments of bridge ramp described above.
