Definitions

  • This invention relates to a ramp apparatus and its method of use.
  • this invention relates to a modular ramp apparatus that can be quickly and easily assembled to provide ramped access to buildings, vehicles, skips, dumpsters and/or other structures, or to traverse obstacles.
  • the invention being particularly useful in construction environments.
  • construction and building sites present challenges in terms of navigating people and products over rough and rutted ground, which is often further complicated because of inclement weather.
  • Construction workers of all professions need to transport, often by hand, various construction and building products around the construction site and often requiring the use of wheelbarrows or other powered or hand- propelled wheeled vehicles.
  • the first stages of the work generally involve ground preparation and levelling of the site, prior to evacuation and construction of the foundation footings. Following these stages, a layer of masonry footings, usually including a damp-proof course, is laid. As such, from this point in the construction, this presents a peripheral step or obstacle that needs traversing, often from surrounding uneven and/or unstable ground, for both site personnel and almost all of the building products that are to be brought on site.
  • ad hoc ramp In order to address this problem, builders and construction workers often attempt to construct an ad hoc ramp, usually using one or more scaffolding boards supported by whatever is to hand to allow wheelbarrow access. These ad hoc structures, by their very nature, are not particularly stable or secure, and the thickness of the scaffolding boards often presents a trip hazard. This is further compounded by the fact that when wheeling a wheelbarrow a user cannot see the floor surface beneath and in front of the wheelbarrow. The width of scaffolding boards used in ad hoc ramps of this type is also narrow. It is not uncommon for trips and falls to occur when using ad hoc ramps, which can cause damage to the building products and surrounding construction area, and more importantly, cause injury to the user.
  • the modular ramp apparatus can be assembled without the use of hand tools, and having connection features that can quickly and reliably interlock during assembly and in use, and equally be disengaged rapidly during disassembly.
  • a ramp apparatus comprising:
  • a support means which is mountable on a second surface, the support means being connectable to the proximal end of the ramp section to provide a sloped surface between the first surface and the second surface when deployed.
  • An advantage of the present invention is that it can be used to quickly and securely form a temporary sloped surface for trafficking and wheeled access.
  • the first surface is selected from the group consisting, but not limited to, any one of the following: ground, road surface, kerbside and the like.
  • the second surface is selected from the group consisting, but not limited to, any one of the following: step, lip, masonry footing, single-leaf wall, double- leaf wall, skip side, dumpster side, vehicle and the like.
  • the maximum incline of the sloped surface when deployed may be no more than 1 :6.
  • the ramp section further comprises:
  • the longitudinal and transverse arms being formed from box profile aluminium.
  • the board may be formed from birch board or the like having non-slip surfaces thereto and/or from a sheet metal having portions of which are chequered, profiled or perforated.
  • the swivelling foot further comprises one or more toes being able to swivel or pivot about a pivoting rod which is held in place between a support wall and side walls positioned at the distal end of the longitudinal arms.
  • the support wall has a cutaway at the uppermost section thereof which allows the board to be received flush on the ramp section.
  • the one or more toes may be formed from 6mm or 8mm gauge steel being chequered, profiled or perforated or moulded from a hard plastics material having apertures at its underside to prevent sliding and clogging by debris when in use.
  • the support means being connectable to the proximal end of the ramp section via an interlocking connection mechanism.
  • the interlocking connection mechanism comprises a transversely- mounted bar positioned at the proximal end of the longitudinal arms and which meets with a complementary-shaped channel disposed on the support means.
  • the bar may be formed as a pair of connection bars which are disposed equidistantly from the ends of a longitudinal arms and are held in place between a support wall and side walls.
  • the bar has a circumferential flat surface formed as a chord whose endpoints both lie on the circumference of the bar.
  • the bar is formed from stainless steel.
  • the channel may be a semi circular groove in cross section, the channel can only receive the circumferential flat surface of the bar when the ramp section is offered in a first configuration.
  • the first configuration is a generally vertical configuration situated above the channel.
  • the groove and the bar interlock in place without the use of hand tools.
  • the support means may further comprise:
  • one or two side walls which extend downwardly from each side of the base; and one or more channels disposed on the one or both of the side walls.
  • the one or more channels are disposed equidistantly from the ends of the side walls.
  • the base wall and the side walls form an open slot.
  • the slot may be dimensioned to receive a masonry footing, single-leaf wall, double-leaf wall, skip side, dumpster side, vehicle and the like.
  • the support means is configured have one side wall for connecting to the side of a step, lip, obstacle and the like.
  • a pair of side support means can be brought together and secured when in use.
  • the support means may be formed from powder-coated steel and having an internal EPDM liner.
  • the ramp section, swivelling foot and support means in combination form a continuous sloped surface between the first surface and the second surface when deployed.
  • the ramp apparatus further comprises a link platform for joining two successive ramp sections together to provide a sloped surface to a third level.

  • the modular ramp apparatus can be assembled without the use of hand tools, and having connection features that can quickly and reliably interlock during assembly and in use, and equally be disengaged rapidly during disassembly.
  • the ramp apparatus 10 is for providing a sloped surface between a first level or surface 12 and a second level or surface 14.
  • the height of the second level 14 is the height of a single layer of brick footing 16.
  • the ramp apparatus 10 comprises an elongated ramp section 18 which is structurally formed from a pair of longitudinal arms 20. Disposed between the longitudinal arms 20 are a plurality of transverse arms 22, as best shown in Figure 13. Positioned on top of the ramp section 18 is a board 24 which may be chequered or perforated (not shown) to provide grip.
  • a swivelling foot 26 Situated at one end of ramp section 18 adjacent to the first level 12 is a swivelling foot 26.
  • the swivelling foot 26 serves two main purposes. Firstly, the foot 26 provides an inclined continuous surface between the first level 12 and the top of board 24. Secondly, the foot 26, being formed from a number of toes 28a, 28b, is self-levelling in that it takes up, and can adjust to, any irregularities in the first level 12, which, on a building site, is often the case with muddy and uneven ground.
  • the toes 28a, 28b are able to swivel or pivot about a pivoting rod 30 which is held in place between side walls 32 positioned at the distal end of the longitudinal arms 20, and as described in further detail in Figure 7.
  • the opposite, proximal end of the ramp section 18 is formed having a pair of side support arms 34 which each project from the proximal end of each of the longitudinal arms 20.
  • Each of the side support arms 34 supports an inwardly transverse-mounted bar 36 which can be received inside one of a pair of channels 38 formed in a support means 40 (as best shown in Figure 4) which, in use, is positioned over the brick footing 16.
  • the support means 40 is formed having a generally rectangular shape in plan view with a generally flat base wall 42 and a pair of side walls 44 which extend downwardly from each side of the base wall 42, such that the base wall 42 and side walls 44 in combination define an open slot being dimensioned in the embodiment of Figure 1 to receive a single brick footing 16.
  • a rubberised or EPDM liner 46 is also included on the interior of the base wall 42 and side walls 44 of the support means 40.
  • the transverse-mounted bar 36 includes a circumferential flat surface 48 formed as a chord whose endpoints both lie on the circumference of the bar 48 and which can only be received within the channel 38 when the ramp section 18 is offered in a generally vertical configuration directly above the channel 38.
  • the flat surface 48 of the bar 36 forms an effective diameter c (as shown in Figure 8) which can be received within channel 38 through opening a (as shown in Figure 4), and then the ramp section 18 lowered down to the first level 12 and held in an interlocking configuration even when subject to vibration or travel or trafficking with a wheelbarrow (not shown) on board 24.
  • Figure 2 shows how the modular ramp apparatus 10 of the present invention can be used instead of traversing a single brick footing 16 to access a skip 50.
  • the base walls 42 and side walls 44 of the support means 40 define an open slot which can receive a side wall 52 of a skip 50 in order to provide a sloped surface for trafficking and wheeled access to the skip 50 from the first level 12, which is usually the road surface or kerb side.
  • FIG 3 shows a second embodiment of the ramp apparatus 10.
  • the construction of the second embodiment is very similar to that of the first embodiment and corresponding features have been given the same reference numerals.
  • the second embodiment differs from the first embodiment in that each of the side walls 44 of the support means 40 includes a pair of channels 38.
  • the advantage of having channels 38 on each of the side walls 44 is that, as can be seen from Figure 3, a ramp section can be used to entirely bridge, i.e. ascend and descend, a masonry footing 16 or obstacle, and further detail of the support means 40 is shown in Figure 5.
  • Figure 4 shows further detail of the support means 40 and shows that a pair of channels 38 are disposed equidistant from the ends of the side wall 44.
  • the length of the side walls 44 extending downwardly from the base wall 42 can be different. This is in no way intended to be limiting as the length of the side walls 44 which extend from the base wall 42 can be identical to form a U-shaped cross section (as shown, for example, in Figure 10).
  • Figure 4 also shows further detail of the channel 38 being used for receiving the connection bar 36.
  • the channel 38 comprises a generally semi circular groove 54 in cross section, which is mechanically supported by member 56.
  • the construction of the support means 40 and ramp section 18 is from galvanised steel, high tensile galvanised steel or aluminium and leads to a welded manufacture in the preferred embodiments of the invention. This is in no way intended to be limiting as the present invention can be implemented using any number of fabrication techniques, sizes, dimensions and materials. Equally, the toes 28 of the foot 26 can be machined, pressed, cast, forged or formed from any suitable metal, including a suitable hard plastics material.
  • the width of the opening a is less than the internal diameter (given by the dimension V) of the groove 54. It is therefore apparent that the circumferential flat surface 48 on the connection bar 36 must be offered up to the side wall 44 in such a manner that the flat surface 48 is adjacent to the side wall 44 and therefore can be received inside the semi circular groove 54. Rotation of the connection bar 36 inside the groove 54 thereby locks the connection bar 36 in place and the ramp section 18 is therefore releasably secured to the support means 40.
  • the ramp apparatus 10 When assembled, the ramp apparatus 10 provides a secure and stable sloped surface for personnel, wheelbarrows, trucks and trolleys to distribute raw materials on building sites, gardens etc.
  • connection bar 36 When the connection bar 36 is held inside the groove 54 it thereby locks the connection bar 36 in place in such a way that to prevent the ramp jumping out by vibration.
  • Figure 5 shows further detail of the support means 40 shown in Figure 3 and it includes a pair of channels 38 disposed generally equidistant from the ends of the side wall 44 of the support means 40.
  • FIG. 6 shows a third embodiment of the ramp apparatus 10.
  • the construction of the third embodiment is very similar to that of the first and second embodiments and corresponding features have been given the same reference numerals.
  • the third embodiment differs from the first and second embodiments in that instead of a pair of side walls extending downwardly from each end of the base wall 42 only one side wall 44 is present, and this allows the side support means 58 to be located on a step or other solid lip of a structure (not shown in Figure 6).
  • the side support means 58 can be used in pairs to surmount, for example, a double brick footing 16 by using two of such side support means 58 positioned in an opposing configuration, as best shown in Figure 12.
  • Figure 7 shows further detail of the foot 26 which is connected at the distal end of the ramp section 18, and is received inside the pair of longitudinal arms 20 (not shown in Figure 7) via C-shaped members 60 which are completely received inside each of the longitudinal arms 20.
  • the C-shaped members 60 can be welded in place or secured using fasteners (not shown) through apertures 62.
  • each of the toes 28a, 28b of the foot 26 includes a series of apertures 64.
  • a support wall 66 is disposed between the side walls 32.
  • the uppermost section of the support wall 66 includes a thin cutaway section 68.
  • the cutaway section 68 allows the board 24 (not shown in Figure 7) to be received flush on the ramp section 18 to reduce trip hazards.
  • connection rod 36 which, in use, is received inside and interlocks with the support means 40.
  • a pair of connection rods 36 are disposed equidistantly from the ends of a support wall 70 and supported by side support arms 34.
  • Received entirely within the longitudinal arms 20 of the ramp section 18 are a pair of C-shaped members 72 which can again be secured using threaded fasteners (not shown) through apertures 74.
  • the uppermost section of the support wall 70 includes a thin cutaway section 76 to allow the board 24 (not shown) to lie flush against the transverse arms 22.
  • the circumferential flat surface 48 on the connection bar 36 ensures that the diameter c, shown in Figure 8, can only be received within dimension a of the channel 38 of Figure 4 when the ramp section 18 is offered and inserted in a generally vertical configuration, as described above.
  • FIGS 9 to 12 show slightly different designs of support means 40 and 58 of the present invention. These versions differ from those described above in that a centrally disposed additional channel 76 is included, but they are otherwise completely described herein and fall within the scope of the present invention.
  • Figure 9 shows a support means 40 configured as a saddle whose dimensions ensure that this will overlap and straddle a single leaf of a two-leaf wall 16 with the channel 38 or locking gutter disposed in the external face of the side wall 44.

  • Figures 17 and 18 show a slightly different version of the foot 26 which includes five toes 28a-28e, and which can adjust to any irregularities in the first level 12, which, on a building site, is often the case with muddy and uneven ground.
  • Figure 18 shows that the toes 28a-28 can be formed from a hard plastics material and include a series of apertures 108 at the under surface thereof to reduce weight and improve adhesion with the first level 12.
  • the foot 26 shown in Figure 17 is formed from standard 6mm or 8mm gauge steel and constructed such that the toes 28a-28e can be swivelled or angled for ease of access.
  • the foot 26 is suspended by a wall 66 traversing the full width, into each side 20 and secured to each supportive side 20 by locking nuts (not shown).
  • the foot 26 is comprised of individual toes 28a-28e which are separated by dividers and have a honeycomb under surface (as shown in Figure 18). This design prevents clogging by debris.
  • the foot assembly 26 is designed such that it can be dismantled for cleaning debris, and/or removal or the installation of replacement toes 28a-28e.
  • Figure 19 shows a slightly different embodiment of the toe 28.
  • a single swivelling toe 28 can swivel or pivot about the pivoting rod 30 which is held in place between side walls 32 at the distal end of the longitudinal arms 20.
  • the materials forming the modular ramp apparatus 10 of the present invention can be selected from the following:
  • the saddles 40, 58 are constructed from powder-coated steel with a lining of EPDM cushion 46.
  • the framework 20, 22 making up the ramp 18 is constructed of box-profile aluminium.
  • the locking bar 36 is constructed of stainless steel.
  • the toes 28 of the foot 26 of the ramp 18 are constructed of EPDM.
  • the link platform 88 can be constructed of box profile aluminium or powder-coated steel with a non-slip birch wood or metal plate as the platform's surface 102.
  • the side barriers/guard rails 80 are constructed of box profile aluminium. To maintain the safety of personnel, in use, the incline for a single ramp 18 and/or dual ramp 18 with link platform 88 is never more than 1 :6.
  • a single ramp 18 is configured to rise to ⁇ 3" (381mm).
  • the dual ramp 18 and link platform 88 is configured to rise to 2' 6" (762mm).
