Definitions

  • the present invention relates to a lift-off hinge assembly for use in hingedly attaching vehicle doors to the vehicle body.
  • hinge assembly One type of such a hinge assembly is a lift-off hinge assembly wherein the hinge leaves are separated by relative movement axially along the pivot axis of the hinge.
  • US-A-4 043 000 It is known from US-A-4 043 000 to provide a hinge which permits two members to be pivoted together as in the case of a door hinge or a drop- leaf table.
  • the hinge disclosed in US-A-4 043 000 includes a first hinge leaf connected to a second hinge leaf for pivoted motion about a pivot axis, each hinge leaf including a body portion from which extends a pair of opposed arms spaced apart along the pivot axis, each arm on one hinge leaf being connected by a hinge formation to a respective arm on the other hinge leaf.
  • Each hinge formation includes a hinge pin projecting from one arm and a hinge pin receiving journal formed in the other arm.
  • the hinge pins of all hinge formations are arranged to co-operate with their respective journals to enable the hinge pins to be simultaneously withdrawn from their respective journals by moving the hinge pins apart along the pivot axis.
  • a vehicle door lift-off hinge assembly including a first hinge leaf connected to a second hinge leaf for pivotal motion about a pivot axis, each hinge leaf including a body portion from which extends a pair of opposed arms spaced apart along the pivot axis, each arm on one hinge leaf being connected by a hinge formation to a respective arm on the other hinge leaf, each hinge formation including a hinge pin passing through and being secured to one arm and projecting therefrom to be received in a journal formed in the other arm, the journal being defined by a bush extending through an aperture formed in said other arm, the hinge pins of all hinge formations being arranged to co-operate with their respective journals to enable the hinge pins to be simultaneously withdrawn from their respective journals by moving the hinge leaves apart along the pivot axis.
  • At least one hinge pin is provided with a removable stop which when mounted on the hinge pin prevents withdrawal of said hinge pin from its journal and thereby prevents separation of the hinge leaves.
  • a liftoff hinge assembly 10 including a hinge leaf 12 which is hingedly connected to a hinge leaf 14.
  • the leaf 12 is in use attached to the vehicle body and the leaf 14 is attached to the vehicle door.
  • the leaves 12, 14 are hingedly connected to one another by two hinge formations 18 which are spaced apart along the pivot axis of the hinge.
  • Each hinge formation 18 includes a hinge pin 19 and a journal 20 for the associated pin 19; the pin 19 being mounted on one leaf and the journal being located on the other leaf.
  • the pin 19 extends through either arm 30, 31 and is preferably secured to its associated leaf by welding.
  • each leaf is provided with one hinge pin 19 and one journal 20 but it will be appreciated that one leaf may be provided with both hinge pins whilst the other leaf may be provided with both journals.
  • the journal 20 is formed by a bush 21 having self lubricating properties such as a metal reinforced plastics bush, the bush 21 being received in an aperture formed in the hinge leaf.
  • the bush 21 also has an annular flange 21a which serves to slidingly space the hinge leaves apart.
  • hinge pins may be used for supporting heavy loads.
  • the pin 19 has a constant diameter shank portion 25 which is preferably only long enough to protrude along the axis of the bush to provide an adequate pivotal connection; in the illustrated embodiment shank portion 25 protrudes along substantially the entire axial extent of the bush.
  • the terminal end 28 of the pin 15 is preferably sharply tapered as shown in order to facilitate entry of the pin into an associated bush particularly during the remounting of a door onto a vehicle body.
  • the upper pin 19 is provided with an annular groove which houses a removable circlip 29 which acts as a stop to prevent withdrawal of the upper pin 19 from its associate journal 20 and thereby prevents axial separation of the hinge leaves.
  • the door may then be moved laterally away from the vehicle body.
  • the distance necessary for raising the door is only the length of the protruding shank portion 25 plus the terminal end 28.
  • the hinge leaves 12, 14 are both conveniently formed as metal pressings and are each provided with spaced apart arms 30, 31 and body portions 32.
  • the arms 30, 31 are provided with hinge formations 18 and the body portions 32 are provided with suitable formations to enable the hinge leaves to be attached to the vehicle door/ body.
  • the embodiment shown in Figures 3 and 4 incorporates a check mechanism 60 which includes a detent 61 in the form of a length of bent resilient metal rod 62 mounted on leaf 12.
  • the detent 61 includes a downwardly projecting arm portion 63 which on relative angular movement of the hinge leaves engages either with star wheel 65 or 66 both of which are rotatably mounted on hinge leaf 14.
  • the portion 63 engages in a recess 67 formed in either star wheel 65 or 66 and on continued relative movement of the hinge leaves is deflected outwardly against the bias of the rod 62 and thereby resists said continued movement of the hinge leaves.

Claims (6)

1. Charnière dégondable par soulèvement pour porte de véhicule comprenant une première lame (12) reliée à une seconde lame 14 pour le mouvement pivotant autour d'un axe de pivotement. chaque lame comprenant une portion de corps (32) à partir de laquelle s'étend une paire de bras en opposition (30, 31) espacés le long de l'axe de pivotement chaque bras sur une lame étant relié par une formation de charnière (18) sur un bras respectif sur l'autre lame, chaque formation de charnière comprenant un pivot (19) traversant fixé sur un bras et faisant saillie à partir de celui-ci pour être logé dans un tourillon (20) formé dans l'autre bras, le tourillon étant défini par une douille (21) s'étendant à travers une ouverture formée dans l'autre bras, les pivots de charnière de toutes les formations de charnière étant disposés de façon à coopérer avec leurs tourillons respectifs pour permettre la séparation simultanée des pivots de leurs tourillons respectifs en écartant les lames le long de l'axe de pivotement.
2. Ensemble de charnière selon la revendication 1, caractérisé en ce qu'au moins un pivot est muni d'une butée amovible qui, lorsqu'elle est montée sur le pivot, empêche l'enlèvement de ce dernier de son tourillon et empêche ainsi la séparation des lames de charnière.
3. Ensemble de charnière selon la revendication 1 ou 2, caractérisé en ce que les deux lames de charnière sont des pièces découpées à la presse à partir d'une tôle métallique.
4. Ensemble de charnière selon les revendications 1, 2 ou 3, caractérisé en ce que chaque pivot comporte une portion de tige faisant saillie (25) dont la longueur axiale est égale ou inférieure à la longueur axiale de son tourillon associé.
5. Ensemble de charnière selon la revendication 4, caractérisé en ce que chaque pivot comporte une portion d'extrémité conique (28) pourfaciliter l'entrée du pivot dans son tourillon associé.
6. Ensemble de charnière selon l'une quelconque des revendications précédentes, dans lequel un mécanisme de butée (60) est monté sur les deux lames de charnière, le mécanisme de butée comprenant un élément de détente (61) constitué par un tronçon de tige métallique plié (62) monté sur une lame de charnière et qui coopère avec une paire de roulettes (65, 66) montée de façon rotative sur l'autre lame de charnière.
