Definitions

  • Wheel construction enabling to roll over threshold
  • the invention relates to a wheel suspension to facilitate the movement of means of transport with wheels or swivel castors, these wheels being mostly mounted at the front side, in the direction of movement, primarily facilitating to negotiate an obstacle like a threshold, an edge or a sudden elevation in the surface in the direction of movement in general.
  • the fork moves forward, causing the centre of gravity of the load to move to the secondary wheel which is above the obstacle.
  • the frame can turn over relative to the fork enabling the main wheel to roll over the obstacle without load.
  • the present invention relates to a wheel suspension enabling a load bearing wheel, either a castor or a fixed wheel, to be guided over an obstacle by a secondary wheel, providing, in a preferred form, two or more cams on either side mounted on the inner surfaces of the side faces of the fork that fit into the specific contour of guiding grooves in the frame, also possible in another form where the side faces of the fork have guiding grooves and the cams are mounted on either side of the frame.
  • the horizontal movement of the frame in the direction of the plane of the wheels and the vertical movement of the frame up and down are restricted by the movement of the cams in the guiding grooves, whereby one of the grooves guides the cam along a path with a specific contour that begins and ends with a specific angle of inclination and the track resembles the form of a sinus.
  • the other guiding groove restricts the movement of the cam or cams by the specific contour on the upper and lower side that resembles the form of a sinus whereby the frame tilts within a specific angle in the plane of the wheels within the borders of movement defined by the motion freedom of the cams in the guiding grooves.
  • the fork and the frame are connected by one or more elastic elements holding the fork and the frame in a specific position and pulling the frame back in the starting position after a movement of the frame relative to the fork.
  • the wheel suspension enables the secondary wheel to slide sideways or tilt over a minor angle in a direction perpendicular to the plane of the wheels and is centred by spring elements.
  • the supporting fork has only one face that is enclosed between two sides of a frame whereby the frame has guiding grooves on the inner side, enclosing cams mounted on the side of the face of the fork.
  • Fig. 1. shows a drawing of the wheel suspension assembly
  • Fig. 2. shows the frame with the main wheel and the secondary wheel
  • Fig. 3 A - F shows the function of the wheel suspension when rolling over an obstacle
  • the wheel suspension 1 consists of a fork 2 mounted to a means of transport, holding a frame 4 between the faces 3 of the fork 2 supporting a main wheel 5 and a secondary wheel 6. This is shown in fig. 1.
  • the respective axes of the wheels 5 and 6 are mounted in the frame 4 with some distance between them and at different heights, as is shown in fig. 2.
  • the frame 4 can move relative to the fork 2 in a direction opposite to the direction of movement of the means of transport and vertically.
  • the freedom of movement of the frame 4 relative to the fork 2 is limited by the guiding grooves 7 and 8 enclosing the cams 9 and 10.
  • the position of the frame 4 in the fork 2 is influenced by the elastic elements 11 mounted between the frame 4 and the fork 2 on both sides.
  • the pair of cams 9 is forced by guiding groove 7 to follow a track resembling a sinus while the pair of cams 10 can move freely within the borders of the guiding groove 8, having the same sinus shape on the upper and lower side.
  • the fork 2 slides forward in the frame 4 forced by the forward movement of the means of transport, thus gradually moving the centre of gravity towards the secondary wheel 6.
  • the centre of gravity is moved forward sufficiently, releasing the load on the main wheel 5 to a value minor to the upward force, the main wheel 5 can roll over the obstacle 13 while the frame 4 turns over.
  • the movement of the frame 4 during the sliding of the fork 2 in the frame 4 is guided by the shape of the guiding grooves 7 limiting the movement of cams 9 and the shape of the guiding grooves 8 enabling the cams 10 to move freely between borders.
  • the shape of the guiding groove 7 enforces the load transfer to the secondary wheel 6 while the guiding groove 8 limits the tilting angle of the frame 4 and thus controls the displacement of the wheels 5 and 6.
  • the secondary wheel 6 can tilt in a direction perpendicular to the plane of the wheels and is kept in a vertical plane by spring elements 14.

Abstract

La présente invention concerne une suspension (1) de roue pour faciliter le déplacement de moyens de transport pourvus de roues ou de roulettes pivotantes, ces roues (5, 6) étant en grande partie montées à l’avant, dans le sens de déplacement, afin de faciliter la négociation d’un obstacle (13), tel qu’un seuil, un bord ou une élévation soudaine de la surface dans le sens de déplacement en général. Une telle suspension (1) de roue peut être appliquée à de nombreux moyens de transport tels que, par exemple, des contenants roulants, des meubles, des conteneurs de transport, des poussettes, des caddies, des fauteuils roulants ou des déambulateurs à roulettes.
