Definitions

  • the present invention relates to a hinge joint, in particular an demountable hinge joint having a locking function to prevent undesired demounting.
  • the first principle consists in that one may loose and remove the shaft around which the joint pivot in one way or the other.
  • the second principle consists in that the shaft around which the joint moves cannot be removed readily, but it is the surrounding of the shaft, which may be opened, removed or moved.
  • the third principle consists in that the site of the shaft is not completely surrounding and that the shaft itself around which the joint moves has a recess which makes the hinge joint keeping together in a number of angles except for one or a couple of angle ranges. This leads to that a permanently open shaft site can be used simultaneously as the shaft can only be removed from the shaft site when the shaft is present in a particular angle in relation to the shaft site.
  • the fourth principle for hinge joints consists in that one uses a cylindrical shaft which of course has its advantages where the shaft site has an opening through which the shaft can be introduced or be removed through and that there are further means besides the shaft site holding the shaft in place towards the opening.
  • hinge joints being separable in the joint: Demounting by removing the shaft around which the joint moves Demounting by opening the shaft site Demounting by providing a permanent opening of the shaft site and by adapting the shaft in such a way that it can be placed in this opening when it is present in a certain angle in the shaft site
  • Demounting by providing an opening in the shaft site and having a cylindrical shaft which can pass through said opening.
  • the shaft is kept in place by means which only indirectly is connected to the shaft and/or the shaft site itself.
  • the present invention relates to the fourth type of these hinge joints.
  • Hinge joints which can be demounted with out any tools often have either one or more parts which shall be removed from the joint before it can be separated, or there are different types of movable parts on the joint that facilitates mounting and demounting.
  • One compromise turns up when one considers the pros and cons between a number of parts or a more expensive construction having movable parts.
  • the joint contains two parts only.
  • One type of demounting takes place by having a shaft which is flattened on one side in such a way that an open shaft site allows demounting when the shaft has a certain angle in relation to the opening of the shaft site.
  • the drawback of these shafts is that it gives the shaft a tendency to jam as the shaft quite often is not completely placed in its site.
  • a well known example to many is the "poly grip" tongs having a bevelled shaft.
  • US-A-992,326 discloses a hinge joint centre, in particular to be used at tilt windows, and has a first partly cylindrical part D having an inner sleeve F surrounding an extended centre hole running up to the periphery, as well as a second circular disc A having a centre shaft C.
  • On either side of the centre shaft there are two screw holes J having part sleeves I 1 I'.
  • the part sleeves I 1 I' are arranged to guide on one hand against the said sleeve F, and on the other hand against the inner side E of the cylindrical part D.
  • EP-A-O 154 266 discloses a releasable hinge joint centre for pivotable ship hatches.
  • the hinge joint may be totally demountable in the particular moment when a centre shaft 8 has been introduced in their recesses and the hatch parts have raised to an upright, vertical position accdoring to Fig 1 of the disclosure.
  • DE-C-588,493 discloses a window hinge having two parts each comprising two part circular units 5 and 6, and 7 and 8, respectively. It is not evident if the hinge is demountable as figure 3 of the disclosure gives the impression that parts 3 and 4 lock each other in an open condition. The hinge is probably demountable in an axial direction of a part 5, probably a vertical direction in a window-frame.
  • the hinge joint to which the present invention is related, can be made in two parts, which can be produced in different materials, e.g., metal or injection moulded polymer or a similar material. These parts may also be integrated in those constructions, which shall be joined to the joint, whereby the number of parts can reach a minimum.
  • the present invention is thus a hinge joint fulfilling the whole list of criteria set forth above stressing rapid mounting and demounting as well as a low production cost.
  • the present invention relates to a hinge joint, in particular a rapidly mountable and demountable, dissembable hinge joint having a locking function to prevent undesired demounting.
  • the invention is characterized in that it comprises two parts of which one first joint part is provided with a substantially perpendicularly thereto protruding shaft and at least two side projections arranged spaced from said shaft and protruding from said joint part.
  • the second joint part is provided with a recess going from the periphery and inwards and arranged to receive the shaft arranged in said first joint part and is provided with at least one circular surface being arranged around said recess and optionally two part tracks running in parallel to the formation of a) a circular or b) a U-shaped track together with parts of said circular surface.
  • the part tracks of the latter embodiment leading to the side edge of the second joint part and to which the circular surface or in which track at least two protruding side projections are arranged to be introduced and to run.
  • the said joint parts are arranged to each other in a hinge joint.
  • said first joint part consists of two counter facing, opposite discs connected to each other at their base with a connecting fastening element, whereby said shaft runs between said counter facing, opposite discs, said second joint part being arranged between said two discs.
  • said recess is arranged to be a shaft site to said shaft and said U-shaped track is arranged concentrically to said shat site and a shaft applied therein.
  • said recess is provided with a waist to removably fix said shaft into said shaft site.
  • said second joint part comprises on either side thereof U- shaped tracks.
  • said first joint part consisting of two counter facing discs comprises side projections arranged on either side and being opposing directed.

  • the second part has the shape of a disc 2 or male part having the width X, the height Y and the thickness Z, maximally corresponding to the space 18 of the fork 1 (FIG. 2). It should be noted that it is in FIG 1 only that the fork is shown in a complete form, in the remaining figures wherein the fork 1 appears it is shown in a cut form.
  • the first joint part will be defined as the fork 1 and the second joint part will be defined as the disc 2.
  • the discs 3 are parallel to each other in a block 4, or fastening element suitably having the width X, and the height 2Q+Z, which gives a space between the discs 3 which is equal to Z.

  • the fork 1 and the disc 2 have the same width and have equal arcs at the front part of the female part 1 as well as on the front part of the main part of the disc 2. This similarity and adaptation of the parts to each other is not necessary from a technical point of view but has been done from esthetical and working environment reasons point of view.

  • the disc 2 is provided with a locking means, which will provide release in one direction only.
  • This means is arranged as follows. On each side of the disc 2, which sides are parallel to the XY-pIane there is a track 11 , which runs in a circle being concentric to the shaft site 8.
