Definitions

  • the invention relates to a hinge.
  • Hinges are known in various types. Basically, a hinge consists of two hinge leafs, having knuckles that pivotally couple the leafs together via a hinge pin.
  • Known hinges can be mass-produced from plate (i.e. sheet) material, e.g. metal or steel plate material, by cutting out leaf preforms from a plate and deforming lateral sections of the preforms (by curling, bending or rolling) to form respective knuckles.
  • the knuckles of the two preforms of a hinge, to be assembled can be axially aligned for receiving the hinge pin.
  • the knuckles can be provided with low-friction bearings/bushings or the like, e.g. for improving hinge action and durability.
  • a disadvantage of such common-type hinges is that they are relatively weak, and can be forced open during burglary attempts e.g. by simply peeling open the hinge knuckles.
  • hinges for heavy-duty operation such as the pivotally coupling of a large/ heavy panel to a frame (e.g. a window to a window frame or a heavy door to a door frame), utilizing only a relatively small number (e.g. only three or only two) of hinges.
  • a relatively small number e.g. only three or only two
  • the application of sturdy, heavy-duty hinges also becomes desirable to replace standard hinges when relatively heavy panels, e.g. including relatively heavy insulating glass panes are to be carried by the hinge.
  • Heavy-duty hinges are known, that include double-wrapped leaf sections (the so called double wrap hinge).
  • double wrap hinge each leaf consists of two layers of plate material, the respective one or more knuckles being made in one-piece with the two layers (which is inherent of the respective deforming process).
  • An advantage of this type of hinge is its high strength (also in a lateral direction), wherein the hinge can still be manufactured economically using the (preferably cold)
  • a serious disadvantage is that the double- wrapped leaf has double the thickness of a regular (single plated) hinge. Besides, the manufacturing of these hinges leads to relatively large loss of sheet material, in view of the leaf preform shapes required to provide such type of hinge.
  • hinges are known (: security hinges") that include blocking pins, extending from one hinge leaf via an opening of the opposite hinge leaf into the respective panel/frame-assembly.
  • security hinges usually require drilling additional pin receiving openings in the respective panel/frame-assembly.
  • the security hinge also requires additional hinge manufacturing steps for welding the security pin on one leaf and providing the respective pin receiving opening in the other leaf.
  • US 122088 discloses a sheet metal (T) strap hinge, wherein the ends of both the straps or strap and leaf extend around and beyond the pintle, and are secured by rivots or screws or bolts with which the hinge is put on.
  • the hinge is made double at its weakest point, viz. at the pintje and at the screw or nail holes nearest to the pintle.
  • GB2405902 discloses a security hinge having a a U-shaped part for mounting in a door frame, and a T-shaped part for mounting in a door.
  • the present invention aims to solve or alleviate the above- mentioned problems.
  • the invention aims to provide a relatively sturdy, durable (heavy duty) hinge that can be manufactured in an economical manner, wherein the hinge can still be relatively compact (particularly relatively thin). Also it is desired to provide a hinge that can provide good protection against burglary.
  • a hinge including a first leaf and a second leaf pivotally
  • the first leaf includes a first outer plate section, at least one first inner plate section extending over an inner side of the first outer plate section, and at least one first knuckle, the inner side of the first outer plate section being partly covered by the at least one first inner plate section.
  • the inner side of the first outer plate section is not entirely covered by the respective one or more first inner plate sections. In an embodiment, it may be covered for example only for about 30%-70% by the one or more first inner plate sections, providing a significant reduction of use of material as compared to e.g. known double wrap hinges.
  • the second leaf can include a second outer plate section, wherein at least one second inner plate section can extends over an inner side of the second outer plate section, the inner side of the second outer plate section being partly covered by the at least one second inner plate section.
  • a respective second (integral) knuckle can be provided linking the second outer plate section to a second inner plate section.
  • the inner side of the second outer plate section is not entirely covered by the respective one or more second inner plate sections. In an embodiment, it may be covered for example only for about 30%- 70% by the one or more second inner plate sections, again providing a significant reduction of use of material as compared to e.g. known double wrap hinges.
  • part of the second leaf mates with or nests in the at least one first inner plate section of the first leaf when the hinge is in a closed condition.
  • a very strong proof hinge wherein the nested parts of the hinge can hold the hinge together in axial direction (i.e. in parallel to the respective hinge axis) when the hinge is in a closed hinge state.
  • the hinge can be made relatively compact yet sturdy.
  • the nested parts can provide a relatively thin hinge (e.g. having a nominal maximum thickness smaller than 10 mm, e.g. only 8 mm) when it is in the closest state, so that it can be easily applied in common hinge applications (e.g. replacing existing hinges).
  • the hinge can include at least two spaced- apart first inner plate sections, in particularly spaced-apart viewed in a direction in parallel with a hinge axis, the at least two spaced-apart first inner plate sections defining an intermediate space there -between, wherein part of the second leaf is arranged to be received by the intermediate space between the spaced-apart first inner plate sections when the hinge is in a closed state.
  • both the first and second leaf of the hinge include the configuration of an outer plate section being only partly covered by one or more respective inner plate sections
  • the inner plate sections of the two leafs are arranged such that they can fall in place on of top of the other (e.g. they mate or nest with one another as mentioned above), when the hinge is in a closed hinge state and viewed in axial direction, in parallel with the respective hinge axis.
  • a very sturdy yet compact (relatively thin) heavy duty hinge can be achieved in an straight -forward manner, and cost-efficiently.
  • the at least one first inner plate section and the at least one second inner plate section can extend next to each other, viewed in a direction in parallel with a respective hinge axis, when the hinge is in a closed hinge state (all the inner plate sections of the hinge in particular extending in parallel, along the same virtual plane). In this way, a very compact hinge construction is achieved.
  • a maximum thickness T of the hinge measured perpendicularly through the leafs) when the hinge is in a closed condition, can be at most 10 mm, for example at most 9 mm, and is preferably 8 mm. These are dimensions that are commonly used by the relatively weak prior art hinges for pivotally connecting a panel to a frame.
  • the present embodiment of the invention can provide the same hinge thickness dimensions, via a significantly stronger hinge constriction.
  • a maximum thickness T of the hinge measured perpendicularly through the leafs when the hinge is in a closed condition, can be smaller than the sum of the maximum thicknesses of the hinge leafs as such.
  • the first leaf includes two spaced-apart first inner plate sections, having opposite edges adjoining an intermediate space for receiving a second inner plate section of the second leaf.
  • the hinge can include only two spaced-apart first inner plate sections, and only one second inner plate section can move into a space between the two first inner plate sections when the hinge is in a closed state (i.e. when the two hinge leafs have been pivoted towards and onto each other).
  • an intermediate second inner plate section can be provided with optional blocking means for engaging a coupling member (hinge pin), such that the blocking means can be nicely integrated within the hinge, out of reach from an environment when the hinge has been closed.
  • an outer side of the at least one first inner plate section that is faced away from the inner side of the first outer plate section, extends over the inner side of the second outer plate section when the hinge is in a closed hinge state.
  • the knuckle of at least one of the leafs are made in one piece with the respective leaf by a plate deformation/bending method, for example by rolling, folding or the-like.
  • the plate deformation can be carried out e.g. in an
  • environmentally friendly low temperature deformation process e.g. a process at or near room temperature (wherein no particular plate heating is carried out for raising the temperature of the plate material to be
  • the manufacturing of the hinge can be carried out without using any sheet welding process.
  • these leaf plate sections can extend along one another without requiring additional fixation welds therebetween, the resulting hinge being sufficiently strong for hinge operation.
  • the hinge includes blocking means for preventing axial removal of the coupling means from the knuckles. In this way, unauthorized hinge disassembly can be achieved, providing good anti-burglary protection. Also, this can prevent undesired axial movement of the hinge coupling means (e.g. hinge pin) during normal hinge operation.
  • the hinge coupling means e.g. hinge pin
  • the blocking means can be configured in various ways.
  • the blocking means can be provided by a rigid blocking member that can be moved between a blocking state to engage to coupling means and a release state to release the coupling means.

  • the blocking member can e.g. be manufactured from the same material as the hinge sections, but that is not required.
  • the blocking means are arranged such, that they are entirely covered by the hinge plate material when the hinge is in a closed position (i.e. with opposite sides of the first and second leaf being swiveled onto each other).
  • one of said inner plate sections of one of the hinge leafs can include the blocking means to that aim.
  • the configuration can be such that access to the blocking means (from an environment) is still prevented, or blocked, in case the hinge has been opened over a relatively small hinge opening angle, e.g. over an angle of 20° with respect to a closed hinge condition.
  • the hinge is suitable to be used in combination with e.g. means for holding a respective panel in a panel ventilation position with respect to a frame (the hinge connecting the panel to the frame, after mounting), the ventilation position allowing a small gap or slit between the panel and frame for ventilation purposes.
  • the coupling means can be a hinge pin having a dedicated blocking recess for engagement of the blocking means.
  • the blocking means can be embedded in one of the inner plate sections of the hinge, for example in case that inner plate section includes an opening for receiving the blocking means.

  • the blocking means cover part of an outer plate section of the hinge, the blocking means including a through-hole that is aligned with a through-hole of the respective outer plate section for receiving a locking element. In this way, the blocking position of the blocking means can be locked in a straight-forward manner via such a locking element (e.g. a screw of bolt), during mounting of the hinge.
