`ABSTRACT
`(57)
`A canopy structure is provided and includes a frame
`work unit and a flexible covering. The framework unit
`is formed by a plurality of upright corner members and
`a plurality of roof support members that are pivotally
`connected at the top ends of the corner members and, in
`an erected position, extend upwardly and inwardly to a
`central apex where they are pivotally connected to one
`another. The roof support members are formed of ex
`tendable sections which preferably telescope with re
`spect to one another so that the framework unit may
`move into a collapsed state with the corner support and
`roof support members oriented in closely spaced, paral
`lel relation. Latches are provided to prevent the frame
`work unit from collapsing from the erected position.
`Constraining and support structure, preferably in the
`form of scissor assemblies, interconnect adjacent corner
`support members to prevent them from moving apart
`past the erect state. The scissor assemblies have one
`portion pivotally connected to the tops of its associated
`corner supports and another portion pivotally con
`nected to slide brackets on its associated corner support
`member. A cantilever member interconnects each roof
`support member and the slide bracket on its associated
`corner support member. The central apex may include a
`spring biased central post to support the peak of the
`covering placed on the framework unit. Several frame
`work units may be formed together into a larger canopy
`Structure.

`
`COLLAPSIBLE CANOPY WITH TELESCOPING
`ROOF SUPPORT STRUCTURE
`

`
`FIELD OF THE INVENTION
`The present invention relates to a collapsible canopy
`structure which is readily portable so it may used as a
`convenient shade screen or shelter, primarily for out
`door activities. As such, the present invention is di
`rected to temporary shelters which may be stored in a
`collapsed state which may be used in an expanded state
`to provide a shelter having a large surface area of pro
`tection. The present invention specifically is directed to
`such shelter which includes a self-contained roof sup
`port structure that telescopically expands with the re
`maining support framework. As such, this invention is
`believed to be an improvement over my U.S. Pat. No.
`4,641,676 issued 10 Feb. 1987 and entitled Collapsible
`Canopy Structure.
`BACKGROUND OF THE INVENTION
`As was discussed in the background of U.S. Pat. No.
`4,641,676, portable shelters have been in existence since
`prehistoric time, but modern times have seen an increas
`ing need for greater sophistication in the quality and
`25
`type of construction in portable shelter apparatus. In the
`last 20 years, this industry has dramatically grown as a
`result of new techonologies in fabrics, support structure
`and design, especially in the fields of lightweight tents
`and mountaineering shelters. These developments mani
`30
`fest themselves in special application fields, but rela
`tively little attention has been paid to the development
`of larger area-shelters that are stored in a small col
`lapsed state but which may be expanded with a mini
`mum amount of effort into sturdy, large area shelters.
`35
`One response to this need is shown in my U.S. Pat.
`No. 4,641,676. This patent shows a portable canopy
`structure having a framework that may be collapsed
`into a stored state yet which may be expanded and
`erected for use. The framework includes a plurality of 40
`upright support members which are interconnected by
`a plurality of scissor assemblies; an internal scissor as
`sembly is provided to support a central post, and a
`covering extends across the tops of the supports and is
`supported thereon in a dome-like manner. This struc
`ture is also similar to that described in U.S. Pat. No.
`4,607,656 issued 26 Aug. 1986, to Carter.
`While the structure shown in the Lynch patent and
`the Carter patent provides significant advantages over
`the earlier prior art noted above, especially in the rela
`SO
`tive ease of both expansion and collapse, they nonethe
`less have some drawbacks. For example, in use, the
`scissor assemblies shown in these two structures are
`under compressive forces. When the scissor assemblies
`are subjected to forces transversely of their plane, the
`combination of this force with the compressive force
`can result in substantial bowing of the scissor assemblies
`and distortion of the canopy framework. Additionally,
`the use of a central scissor assembly extending across
`the middle of the framework can be inconvenient in
`reducing the head room provided for persons sheltered
`by the canopy structure.
`In addition to the structure shown in the Lynch pa
`tent and the Carter patent described above, other prior
`art structures have been developed to provide tempo
`65
`rary shelters. For example, French Patent No. 823,693
`issued to Boeuf and published 25 Jan. 1938 shows a
`framework for supporting a shelter wherein the frame
`
`4,779,635
`2
`work has a plurality of upright posts which are inter
`connected by single scissor assemblies. A plurality of
`roof support elements are then bolted to each upright
`posts and are then secured together by means of a cen
`tral wing-nut assembly to define a peak for the frame
`work. U.S. Pat. No. 2,928,404 discloses a collapsible
`shelter wherein upright posts pivotally secure rigid roof
`support elements so that the structure may fold to
`gether.
`Accordingly, despite the advances of the abovedecs
`ribed canopy structures, there remains a need for fur
`ther improved canopy structure which provides a quick
`erectable temporary shelter which is easy to expand for
`use and to collapse for storage in a fast, efficient man
`ner. There is a further need for such an improved can
`opy structure which increases the mechanical strength
`of the framework and which provides greater head
`room thereby more efficiently using space.
`SUMMARY OF THE INVENTION
`It is an object of the present invention to provide a
`new and useful canopy shelter which can be collapsed
`for compact storage yet quickly and easily erected for
`S.
`Another object of the present invention is to provide
`a collapsible canopy structure complete with a folding
`roof support structure that extends upwardly and in
`wardly of the corners of the canopy framework unit to
`an apex portion.
`A still further object of the present invention is to
`provide a canopy structure that has increased head
`OO
`Yet a further object of the present invention is to
`provide a canopy structure that outwardly biases its
`corner support members so that the framework inter
`connecting adjacent corner support members is placed
`in tension rather than compression.
`It is a still further object of the present invention to
`provide a spring biased roof support structure for a
`canopy framework in order to maintain the canopy
`covering in a taut manner at all times.
`The canopy structure according to the present inven
`tion accordingly comprises a canopy framework unit
`that mounts a canopy top in order to provide a tempo
`rary shelter. The framework unit is readily collapsible
`for storage yet expandable for erection. The framework
`unit includes a plurality of upright corner support mem
`bers each of which having a bottom end which is posi
`tionable upon a support surface, such as the ground, a
`floor and the like, and a top end opposite the bottom
`end. These corner support members are oriented along
`side one another in the collapsed state and are moved
`outwardly apart from one another in the expanded
`State.
`A plurality of roof support members are pivotally
`connected to one another on first pivot axes at first ends
`thereof to define an apex located centrally of the can
`opy framework unit. The roof support members then
`project radially outwardly from the apex, preferably at
`equiangular locations and terminate at second ends
`which are each pivotally connected on a second pivot
`axis to the top end of a respective corner support mem
`ber. Each corner support member and its associated
`roof support member thus may be folded about the
`second pivot axis into the collapsed state with the roof
`support members simultaneously being folded about the
`first pivot axes so that all of the roof support members
