Definitions

  • the present invention relates to a clamp apparatus and particularly, but not exclusively, to apparatus for holding an item such as a door.
  • the base members at their adjacent inner end portions are able to oppositely pivot upward away from the floor to a higher elevation than the outer end portions of the base members by virtue of the hinge.
  • the slot between the upright clamp members is widened so as to facilitate ready positioning of a door in the apparatus.
  • the base members may also oppositely pivot downward toward the floor and thereby locate at a lower elevation than that of the outer end portions of the base members. This movement results in the upright clamp members moving towards one another and allows a door placed within the aforementioned slot to be gripped by the clamp members. The door may be thereby firmly held by the prior art apparatus .
  • a problem associated with the above prior art apparatus is that the weight of the door bears upon the hinge and can result in the upright clamp members gripping the door located therebetween so tightly that the apparatus tends to become jammed and the door difficult to release.
  • the apparatus also tends to locate in a clamping position under the action of gravity and this can make it difficult to position an item between the clamp members .
  • the present invention provides a clamp apparatus for holding an item in a generally vertical plane, the apparatus comprising two members for clamping about an item; and biasing means for biasing the two clamping members from a clamping position towards a release position wherein the distance between the clamping members is greater in the release position than in the clamping position.
  • the biasing means may mechanically secure the two clamping members to one another.
  • the biasing means may mechanically secure the two clamping members to one another so that said members are rotationally movable relative to one another between the clamping position and the release position. It may also be preferable for the biasing means to be adjustable in such a way as to allow the distance between the clamping members, when said members are in the release position, to be selectively varied.
  • the biasing means is telescopically mounted to one of the clamping members.
  • the clamping member to which the biasing means is telescopically mounted may be provided with means for selectively securing the biasing means to the biasing member.
  • the spring is positively clamped against movement in either direction so that the gap between the jaws is maintained even when not in use.
  • the spring is permanently fixed in one jaw and clamped to the other, for example, by a thumb wheel.
  • means are ideally provided for allowing the bias of the biasing means to be overcome when, in use, an item to be clamped is rested on said apparatus between the clamp members.
  • the means for allowing the bias of the biasing means to be overcome may comprise a foot member extending from each clamping member, the foot members being located on either side of the space between the clamping members in which, in use, an item clamped by the clamping members is positioned.
  • the biasing means may comprise a spring which may be a leaf spring.
  • Figure 1 is a schematic side view of apparatus according to the present invention
  • Figure 2 is a schematic end view of the apparatus of Figure 1 ,- and
  • Figure 3 is a schematic side view of the apparatus of Figure 1 in use clamping a door.
  • each gripping member 4, 6 is fabricated from a single sheet of metal and comprises a base member 8, 10 from inner end portions 12, 14 of which a clamp surface 16, 18 upwardly extends.
  • Each gripping member 4, 6 also comprises a reinforcing web portion 20, 22 which extends from one edge of the associated clamp surface 16, 18 to an edge of the associated base member 8, 10. The gripping members 4, 6 are thereby stiffened and the clamp surfaces 16, 18 are less likely to bend relative to their respective base members 8, 10 during use.
  • the support pads of the clamping apparatus 2 are provided as metal feet members 24, 26 which are located at the outer end portions 28, 30 of the base members 8, 10.
  • the feet members 24, 26 project downwardly from the lower surface of the base members 8, 10 and have the effect of raising the base members 8, 10 off the floor on which the apparatus 2 is placed during use.
  • the surface of the feet members 24, 26 which, in use, engages the floor is preferably adapted to allow the base members 8, 10 to readily rotate.
  • the surface of the feet members 24, 26 engaging the floor is therefore ideally curved.
  • the hinge means of the clamping apparatus 2 is provided as a leaf spring 32 which extends between inner end portions 12, 14 of the base members 8, 10.
  • the leaf spring 32 is permanently secured to the inner end portion 12 of the first gripping member 4 and releasbly secured to the inner end portion 14 of the second gripping member 6.
  • the leaf spring 32 has sufficient stiffness to substantially prevent the inner end portions 12, 14 from rotating downwardly about the feet members 24, 26 under the weight of the clamping apparatus 2.
  • the leaf spring 32 is releasbly secured to the second gripping member 6 in such a way as to allow the size of the slot between the clamp surfaces 16, 18 to be varied.
  • the leaf spring 32 extends through an aperture (not shown) in the clamp surface 18 of the second gripping member 6 and locates over a boss 34 in which a screw threaded hole 36 is provided (see Figure 2) .
  • the leaf spring 32 is itself provided with a plurality of holes (not shown) along its length and any one of these holes may be aligned with the screw threaded hole 36.
  • the width of the slot between the clamp surfaces 16, 18 is varied depending upon which hole in the leaf spring 32 is aligned with the screw threaded hole 36.
  • the leaf spring 32 may be secured in position by locating a screw threaded bolt 38 through the spring hole and into screw threaded engagement with the screw threaded hole 36.
  • the width of the slot between the clamp surfaces 16, 18 may be varied to best suit the width of the door or other item to be placed therein.
  • the spring is of a broad spring plate type, it provides a good support, even for relating soft materials, which assists in preventing damage to an object that is being clamped.
  • any slot width (rather than predetermined slot widths) may be selected within a given range .
  • the clamp surfaces 16, 18 are each provided with a resiliently compressible pad which serves to protect the item which is clamped in use.
  • the pads 40 may be manufactured from a rubber material.
  • the pads 40 have cutaway portions at their upper and lower ends .
  • the cutaway at the lower end enables there to be an upward flexing of spring 32.
  • the gap (ie the aforementioned slot width) between the clamp surfaces 16, 18 is adjusted by telescopically lengthening or shortening the leaf spring 32 extending between the gripping members 4, 6 so as to allow a door 42 (or other item to be gripped) to be readily located between the clamp surfaces 16, 18.
  • the distance between the pads 40 of the gripping members 4, 6 should be only marginally greater than the thickness 44 of the door 42 (see Figure 3) .
  • the inner end portions 12, 14 of the base members 8, 10 move downwardly and the clamp surfaces 16, 18 move towards one another and grip about the door 42.
  • the pads 40 on the clamp surfaces 16, 18 which physically engage the door 42 and thereby protect the door 42 from being damaged.
  • the pads 40 resiliently deform and ensure a high friction grip on the door 42.
  • the present invention is not limited to the specific embodiment described above. Alternative arrangements and suitable materials will be apparent to a reader skilled in the art.
  • the leaf spring may be permanently secured or, alternatively, releasably secured, to both gripping members 4, 6.
  • alternative means for biasing the gripping members 4, 6 into the release configuration may be provided.
  • the gripping members 4, 6 may be pivotally connected to one another by means of conventional hinge and biased into the release configuration by means of a helical compression spring extending downwardly into engagement with the floor from each inner end portion 12, 14.
