Suspension Hook
The present invention encompasses an arrangement (1) related to a suspension hook with a discrete anchorage portion fixable via fixing means (3,(3)), to a vertically orientable support (2) and a discrete hook portion (5) coordinated with the anchorage portion. Said anchorage portion (4) displays an elongate surface section (4a) with barbs (6), while said hook portion (5) displays a short surface section (5a) with corresponding barbs (7,8) in order, in a position with the barbs cooperating, to cause the retention of said hook portion (5) against the anchorage portion (4) in one set position selectable from among a plurality of such positions. A vertically directed loading (‘F’) acting on the hook portion (5) is adapted to be absorbed by a cooperation between said barbs (8) allocated to the hook portion and barbs (6) allocated to the anchorage portion. Said surface section (5a) associated with the hook portion displays two series-oriented surface sections, a first surface section (8) structured with said barbs (7) and a superjacent, adjacent second surface section (9) which is structured planar. Said barbs (8) are disposed to be oriented adjacent and laterally oriented in relation to a lower plane (‘P’) allocated to the lower surface of the second surface section (9).
The present invention relates in general to an arrangement which is directly related to a suspension hook, and more specifically to a suspension hook which is adapted for cooperation with a vertically orientable support, and which displays a, hereinafter referred as “anchorage portion” fixable to the support and adapted, via discrete fixing means, to be fixable against said support and a “hook portion” or catch portion coordinated with the anchorage portion and formed as a discrete unit.
More particularly, the suspension hook is intended to utilise an anchorage portion which displays a vertically directed elongate surface portion with a first set of barbs or other unevenness, and a hook portion which displays a surface section with a corresponding second set of barbs in order, in a position of cooperation of the sets of barbs, to retain said hook portion against the anchorage portion in a position set from among a plurality of optional positions and where a vertically directed load acting on the hook portion is adapted to be absorbed by said barbs allocated to said anchorage portion and said barbs allocated to said hook portion.
More particularly, the present invention relates to an arrangement in a suspension hook, where the hook portion, in a selected position, may assume a fixed and retainable cooperation with the anchorage portion, where this retainable cooperation may advantageously increase in dependence upon the size of the load disposed at the hook portion, and where the hook portion may in a simple manner be displaced to a vertically related position selected from among a plurality of optional positions.
The fixed cooperation is based on the feature that the first set of barbs allocated to the anchorage portion is, in fixed cooperation with the second set of barbs allocated to the hook portion while the intimated vertically related displacement is to be able to take place without such fixed cooperation.
BACKGROUND ARTMethods, arrangements and constructions relating to the above-disclosed technical field and disclosed property are previously known in the art in a plurality of different embodiments.
As then regards different hook arrangements of the nature disclosed by way of introduction, there are previously known in the art a plurality of different such arrangements comprising: a discrete anchorage portion fixable to a vertically orientable support via fixing means, a hook portion or catch portion discretely coordinated with this discrete anchorage portion; and where different means have been proposed in order to be able to retain said hook portion against the anchorage portion in a set position selectable from among a plurality thereof in order by such means to be able to vertically regulate an object suspended in said hook portion.
As a result of suspension hooks, composed of a plurality of said fixable anchorage portions and said displaceable hook portions the requirement is considerably reduced on causing orientation of the discrete fixable anchorage portion exactly at a predetermined vertical state or a position.
The state of the art also includes the contents in the following Patent Publications.
U.S. Pat. No. 6,557,813
This publication shows and describes an apparatus for making possible suspension of an object against a wall or a wall section and where the apparatus utilises a vertical guide (22) and a horizontally oriented rod (44) mounted at a body (30) displaceable in the vertical direction, where the rod (44) and the body are displaceably disposed along the vertical guide (22) and securable in one of four predetermined distinct positions.
More particularly, this disclosure calls for the utilisation of an additional horizontal rod (46) which is to be able to be displaced horizontally along the horizontal rod (44).
When the apparatus is to be put to use, the guide (22) is to be secured to the wall and a wall section while the additional rod (46) is to be secured to the rear side of a photograph or other article or the like which is to appear hanging along the wall section.
The distinct position of the article may be regulated by causing the displacement of the body (30) in steps along the guide (22) and/or the additional rod (46) along the horizontal rod (44).
U.S. Pat. No. 6,003,825
This publication discloses and describes an apparatus for being able to adjust a hanging object where a first rod (12) is adapted for cooperation with a wall section in a horizontal direction and a second rod (16) is oriented at right angles to said first rod and is provided with one or more hooks (30a) for cooperation with a wire which is secured to the object which is to assume a hanging position.

The second portion (10) supports hook-displaying means (14) from which a selected object (4) can hang.
The second portion (10) is displaceably disposed in a horizontal direction while the third portion (12) is displaceably disposed in a vertical direction in order thereby to be able to adjust the hook-displaying means (14) in both a horizontal and a vertical direction.
NL-C-1 010 054This publication discloses and describes a hook arrangement where a first subportion (14) is fixable to a wall portion (7) and where a subportion (2) folded through 180° displays not only a hook-displaying means (4) but also moreover is formed with a slot (5) through which a screw (6) is intended to extend.
One alternative embodiment is produced and shown in FIG. 6 and there displays a hook subunit (21) of one piece formation and an anchorage subunit (19) of one piece formation with an inner “T” shaped groove (20) cooperating with one another via barbs or tooth shaped diverging side portions (23) and the edge portion (24).

SolutionIn such instance, the present invention takes as its point of departure the prior art as disclosed by way of introduction and where this prior art is based on an arrangement which is related to a suspension hook with a discrete anchorage portion fixable via fixing means to a vertically orientable support, and with a discrete hook portion or catch portion coordinated with the anchorage portion, said anchorage portion displaying an elongate surface portion with barbs and said hook portion displaying a short surface portion with corresponding barbs in order, in a position with the barbs cooperating, to fixedly retain said hook portion against the anchorage portion in one set position selectable from among a plurality thereof and where a vertically directed loading acting on the hook portion is adapted to be absorbed by and offer a cooperation between aid barbs associated with the hook portion and barbs associated with the anchorage portion.
In order to be able to resolve one or more of the above-disclosed technical problems, the present invention particularly discloses that the prior art is to be supplemented with the feature that said surface portion associated with the hook portion is to display two series-oriented surface sections, a first surface section structured with said barbs and an adjacent second surface section structured in any event with a slidable, for example planar, lower surface.
In addition, it is disclosed that said barbs are to be disposed and be oriented adjacent and laterally oriented a second lower plane associated with the surface section and connecting to the planar lower surface.
As preferred embodiments falling within the scope of the basic concepts of the present invention, it is moreover disclosed that said surface section associated with the hook portion is adapted to merge, with said first surface section, into an integrated short planar surface section however slightly longer than said surface section.
The present invention also discloses that the planar surface section is to be oriented adjacent a spiculated hook portion or end portion allocated to the hook portion.
Said planar surface section is to be related to a thin tongue-like portion and thereby be resilient on an activating compressive force against the spiculated end portion of the hook portion.
The present invention further discloses that a rotation, caused by the activating compressive force, of the hook portion about an allocated axis of rotation against a resilient counterforce generated by the anchorage of the thin tongue-like portion in the hook portion, is adaptable in order to release the barbed surface section of the hook portion from the elongate barbed surface section of the anchorage portion and thereby create a simple displacement of the hook portion along the anchorage portion, from a first selected set position to a second selected position from among a plurality of other selectable positions.
In particular, the present invention discloses that said hook portion is to display an elongate recess or a cavity adapted for free cooperation with a rail associated with the anchorage portion and where said cooperation makes for a stop of said rotation of the hook portion under a loading.
The present invention further discloses that said cooperation is to be adapted so as to form an abutment for the rotary movement of said hook portion in a position where the barbs cooperate.
In such instance, the present invention discloses that said rail is to be formed with a thin or narrow portion facing towards the anchorage portion and a broad portion facing away from the anchorage portion for the formation of a “T” formed in cross section.
According to the illustrated embodiment, it is proposed that barbs, oriented on each side of the narrow portion of a rail are to be given a width corresponding to twice the width of said narrow portion.
The present invention further discloses that an end portion is to be adapted so as to extend towards and ideally somewhat past the end termination associated with the planar surface section.
Said tongue-like portion is to be adapted to extend past a centre line allocated to the hook portion.
According to the invention, it is further disclosed that said planar surface section is to be disposed to extend towards and an adapted distance past said axis of rotation.
There is further disclosed a specific relationship between the longitudinal extent of the planar surface section and the barbed surface section and where this relationship is to be selected to be greater than 1:1, preferably less than 2:1.

More particularly, it is disclosed that said barbed first surface section is to be adapted to extend over said planar second surface section a distance corresponding to or slightly exceeding a depth allocated to the barbs.
More particularly, the present invention discloses that said loading is to be adapted to be able to press barbs associated with the hook portion against barbs associated with the anchorage portion and this may then be offered in that barbs are structured as a saw tooth form with bearing surfaces formed from a portion with an acute angel to said plane.
AdvantagesThose advantages which may principally be deemed to be characteristic of the present invention and the specific significative characterising features disclosed thereby are that there have hereby been created the preconditions in order, in an arrangement related to a suspension hook, to created the preconditions in order, with the aid of a utilised hook portion, integrally formed with a resilient and tongue-like portion, where the hook portion displays a surface section associated with the hook portion which is to display two series-oriented surface sections, a first surface section structured with barbs and an adjacent second surface section structured to be planar.
The barbs are related to an anchorage portion in a first set and barbs are related to a hook portion in a second set and that, during a displacement movement of the hook portion along the anchorage portion, these are released from one another and when a set position is reached to permit corresponding barbs to cooperate with one another and in addition cause said barbs to be disposed and oriented adjacent and laterally oriented a lower plane allocated to the second surface section.
That which may principally be deemed to be characteristic of the present invention is disclosed in the characterising clause of appended Claim 1.

Said anchorage portion 4 displays an elongate surface section 4a with series-oriented barbs 6, and said hook portion 5 displays a surface section 5a with corresponding barbs 7.
More particularly, this is a matter of the feature that said anchorage portion 4 is to display an elongate, vertically directed surface section 4a with a first set of barbs 6, and that said hook portion 5 is to display a short vertically directed surface section 5a with a second set of corresponding barbs 7, where the barbs 6 and 7 correspond to one another.
In a position of cooperation for the barbs 6, 7 (see
More particularly, it is illustrated that said barbs 7 associated with the hook portion are related to the surface section 5a associated with the hook portion which displays two series-oriented surface sections 8, 9, a first surface section 8, structured with said barbs 7 associated with the hook portion and an adjacent second surface section 9 structured slidably over the barbs 6, for example planar, and that said barbs 7 are to be disposed and be oriented adjacent and laterally oriented a lower plane “P” allocated to the lower plane of the second surface section 9.

A rotation, caused by an activating compressive force “F1” (see
Said hook portion 5 displays an elongate recess 10 or a cavity adapted for free cooperation with a rail 11 associated with the anchorage portion and where said cooperation makes for a stop of a rotational tendency of the hook portion 5 under a loading “F”.
Said cooperation is adapted to form an abutment for said hook portion 5 in a position of cooperation of the barbs 6, 7, according to
More specifically, it is disclosed that said rail 11 is formed with a thin or narrow portion 12 facing towards the anchorage portion 4 and a broad portion 13 facing away from the anchorage portion 4 for forming a “T” in cross section.
