Abstract
Abstract In framework sections for awnings link arrangements are used in which the link bodies are connected to each other by means of cotter pins or similar devices. According to the invention two link bodies (1 and 2) are joined to each other by means of a hook (15, 16, 17) and an eye (6,7,8) so shaped that the two link bodies (1 and 2) are movable in relation to each other in transverse direction only in a predetermined relative position and that the two link bodies are pivotable in relation to each other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
A link arrangement, preferably for framework sections for awnings, wherein said link arrangement comprises a number of link bodies connected together, a first link body at one end of the link arrangement including means for anchoring said link arrangement, a further link body at the other end of the link arrangement, and at least one intermediate link body, eye means on each of two of said link bodies, hook means on the third link body and on one of said first two link bodies cooperating with and engaging said eye means and pivotally joining adjacent link bodies, said hook means and eye means being so shaped that transverse relative movement between the two pivotally joined link bodies is possible only in a predetermined position, each hook means comprising a tubular portion with a slit defined longitudinally therethrough, each eye means comprising an aperture defined between a pair of laterally spaced spacers secured to and extending from an adjoining link body, and a cylindrical body secured to and between said spacers outward of the corresponding link body, each said hook means engaging within the corresponding aperture between the spacers with the cylindrical body transversely slidably received within the corresponding tubular portion and, upon alignment of the hook means and aperture, rotatable relative thereto.
Claim 2
Dependent Claim
212 words
A link arrangement, preferably for framework sections for awnings, wherein said link arrangement comprises a number of link bodies connected together, a first link body at one end of the link arrangement including means for anchoring said link arrangement, a further link body at the other end of the link arrangement, and at least one intermediate link body, eye means on each of two of said link bodies, hook means on the third link body and on one of said first two link bodies cooperating with and engaging said eye means and pivotally joining adjacent link bodies, said hook means and eye means being so shaped that transverse relative movement between the two pivotally joined link bodies is possible only in a predetermined position, each hook means comprising a tubular portion with a slit defined longitudinally therethrough, each eye means comprising an aperture defined between a pair of laterally spaced spacers secured to and extending from an adjoining link body, and a cylindrical body secured to and between said spacers outward of the corresponding link body, each said hook means engaging within the corresponding aperture between the spacers with the cylindrical body transversely slidably received within the corresponding tubular portion and, upon alignment of the hook means and aperture, rotatable relative thereto.
Claim 3
Dependent Claim
25 words
A link arrangement according to claim 1, wherein said further link body and said intermediate link body are interchangeably engageable with said first link body.
Claim 4
Dependent Claim
147 words
A link assembly comprising multiple interengaging link bodies including at least first, second and third link bodies, said first link body including anchor means for mounting the first link body to a support structure, pivotally cooperating first hook and eye elements on said first and third link bodies for a selective pivotal linking of said first and third link bodies, said second link body including second hook and eye elements pivotally engageable respectively with the eye and hook elements on said first and third link bodies for selective pivotal linking of said second link body to and between said first and third link bodies, each eye element comprising an aperture defined by a pair of laterally spaced spacers secured to and extending outward from the corresponding link body, and a cylindrical body secured to and extending between said spacers in outwardly spaced relation to the link body.
Claim 5
Dependent Claim
147 words
A link assembly comprising multiple interengaging link bodies including at least first, second and third link bodies, said first link body including anchor means for mounting the first link body to a support structure, pivotally cooperating first hook and eye elements on said first and third link bodies for a selective pivotal linking of said first and third link bodies, said second link body including second hook and eye elements pivotally engageable respectively with the eye and hook elements on said first and third link bodies for selective pivotal linking of said second link body to and between said first and third link bodies, each eye element comprising an aperture defined by a pair of laterally spaced spacers secured to and extending outward from the corresponding link body, and a cylindrical body secured to and extending between said spacers in outwardly spaced relation to the link body.
Claim 6
Dependent Claim
63 words
The link assembly of claim 3 wherein each hook element comprises a tubular portion secured to and positioned transversely of the corresponding link body immediately outward thereof, said tubular portion being of a size to slidably receive a cylindrical body therein for alignment with a corresponding aperture, said tubular portion being receivable within the corresponding aperture for pivotal rotation about the cylindrical body.
Claim 7
Dependent Claim
99 words
The link assembly of claim 4 wherein the tubular portion of each hook element has a slit defined longitudinally therethrough, said slit being of a width comprising a minor portion of the circumference of the tubular portion and being only sufficient to closely receive the spacers of a cooperating eye element therethrough upon alignment therewith for sliding reception of the corresponding cylindrical body within the tubular portion, whereby rotation of the hook element tubular portion into the aperture will move the slit out of alignment with the spacers and preclude withdrawal of the cylindrical body from the tubular portion.
Claim 8
Dependent Claim
27 words
The link assembly of claim 5 wherein said first eye element is on said first link body, said first hook element being on said third link body.
