Abstract Of The Disclosure

The invention provides an improved collapsible tent and tent frame of the umbrella

type. The frame includes a plurality of legs pivoted, at the upper ends of the legs, to

an upper clevis member. Each leg has pivoted thereto a radial stay member spaceddownwardly from the upper end of the leg. The stay member extends inwardly of the

tent to be pivoted to a lower clevis. The upper clevis includes a central downwardlyopening recess and the lower clevis has fixed thereto an upperwardly projection post

or rod which is adapted to engage the upper clevis so as to stop movement of thelower clevis. Each leg comprises an elongated lower section which can be relatively

stiff. The upper end of the lower section is pivoted to an upper section which isrelatively flexible and resilient so that the upper portion of the legs can conform to

the dome of the sheet material forming the tent cover or ceiling.

Collapsible Tent And Frame Therefore

This invention provides an improved collapsible tent and tent frame, more

particularly of the type commonly called an umbrella tent.

Background Of The Invention

Umbrella tents have long been known and widely used. Collapsible umbrella tents of various types go back at least to the turn of this century and have usually included a

collapsible frame on which the fabric or other flexible sheet material of the tent issupported when the tent has been erected. The term "umbrella tent" is commonly

used in the trade because the frames for such tents can be erected and collapsed inmuch the same manner as an umbrella. Typical tents of this type are shown, for

example, in the following United States of America patents:

Shulze et al3,794,054

Watts4,033,366Forget

Though such tents have achieved considerable popularity and commercial success,

there has been a continuing need for improvement.

Summary Of The Invention

Considered broadly, tents according to the invention are of the umbrella type andcomprise a collapsible frame including a plurality of legs pivoted at their upper ends

to an upper clevis member. At points spaced downwardly from their upper ends,

each leg has pivoted thereto a radial stay member extending inwardly of the tent tobe pivoted to a lower clevis. The upper clevis includes a central downwardly openingrecess. The lower clevis has fixed thereto an upwardly projecting post or rod adapted

to engage the upper clevis so as to stop upward movement of the lower clevis. Eachleg comprises an elongated lower section which can be relatively stiff and the upper

end of the lower section is pivoted to an upper section which is relatively flexible andresilient so that the upper portions of the legs conform to the dome of the sheet

material forming the tent cover. The sheet material advantageously can include acomplete or partial floor portion and the lower ends of the legs of the frame engage

the floor when the tent is erected. Advantageously, the legs and stays of the frame

are of extruded polymeric tubing. The clevis members are molded from polymericmaterial, as are all of the pivotal connector members of the frame.

Detailed Description Of The Invention

In the particularly advantageous embodiment of the invention illustrated, tent

frame 1 comprises four legs each comprising a lower section 2 and an uppersection 3, the two sections being pivotally connected by a pivot connector 4 and the

upper section being pivoted to the upper clevis member of a clevis assembly 5. Legsections 2 and 3 are hollow extrusions of suitable polymeric material, typically

polyvinyl chloride. Pivot connectors 4 are also of polymeric material and areadvantageously formed by injection molding from glass fiber-reinforced polyester

composition.

The upper and lower leg sections are identical and, as seen in Fig. 3, have transversecross sections which are in the form of an elongated rectangle having longer sides 6

and shorter sides 7. Inwardly projecting flanges 8, projecting from the longer sides

and spaced apart equally from the center of the rectangle, are provided. Throughoutits length, each leg section has a reinforcing insert 9 having a transverse cross

section in the form of a right angle cross, the edges of the inserts being engagedrespectively in the junctures between of flanges 8 with side walls of the rectangular

leg sections.

Lower leg sections 2 are disposed with the long sides of their rectangular cross

sections directed inwardly of the tent so that these sections are relatively stiff against forces directed inwardly from the outside of the tent frame. Upper leg

sections 3 are disposed with the longer sides of their rectangular cross sections atright angles to the long sides of the rectangles of the cross sections of the lower leg

sections so that the upper leg sections can more readily bend to follow the curvaturenecessary to lead to the upper clevis member of the clevis assembly 5.

Advantageously, clevis assembly 5 comprises an upper clevis member 10, a lowerclevis member 11 identical to member 10, and a center post 12. Each clevis member

comprises a main body 13 having a central through opening 14 and a downwardly

opening generallycup-shaped recess 15. Spaced clevis flanges 16 project radiallyoutwardly from main body 13. At the bottom of the main body, reinforcing flanges 17

interconnect the adjacent flanges 16, as seen in Fig. 4.

As best seen in Fig. 5., center post 12 has a main body 18 of larger diameter, anupper end 19 of smaller diameter joining body 18 in upwardly directed shoulder 20,

and a smaller diameter lower portion 21 which joins main body 18 at downwardlyfacing shoulder 22 and is threaded at its lower end. Lower portion 21 extends

downwardly through the central opening of lower clevis member 11 and is secured tothat member by the combination of upper washer 23, lower washer 24 and nut 25,

as seen in Fig. 5. Seated on upper shoulder 20 is a stop member 26 dimensioned

8/6/2019 Shad Patent

http://slidepdf.com/reader/full/shad-patent 8/15

and shaped to fit slidably within the downwardly opening recess 15 of the upperclevis member.

At a point intermediate its length, each upper leg section 3 is provided with a pivot

member 27, Figs. 8 and 9, and radial brace members 28 each have one end pivotedto one of members 27 and the other end pivoted between one set of flanges 16 of 

lower clevis member 11. The positions of members 27 and the length of members 28are such that when the tent is erected as seen in Fig. 1 lower clevis member 11 isforced upwardly, bringing stop member 26 fully into the recess 15 so that

member 26 is stopped by clevis member 10 with portion 19 of center post 12received in through bore 14 of the upper clevis member.

As seen in Figs. 6 and 7, pivot connectors 4 are of generally U-shaped transversecross section, side wall portions 30 being spaced apart by a smaller distance than

side wall portions 31 so that the right angle displacement between leg portions 2and 3 can be accommodated in the manner shown. As seen in Fig.7, the bottom

wall 32 has a first portion 33 and a second portion 34 and these portions aredisplaced from the pivotal axes of leg members 2 and 3 by distances such that taking

into consideration the 90° displacement between the leg portions, the leg portionsare freely pivotable between the positions shown in Figs. 1 and 2. Advantageously,

an upstanding rib 35 is provided at the free end of portion 33 and a rib 36 isprovided at the free end of portion 34, the heights of these ribs being such that, with

parts positioned as seen in Fig. 1, the end portions of the leg portions engage therespective ribs in the manner seen in Fig. 7. A reinforcing rib 37 is advantageously

provided at the juncture between portions 33 and 34, as seen in Fig. 7.

Members 27 are identical and are advantageously cut from extruded lengths having

thecross-sectional configuration seen in Fig.8 . Each member 27 has a baseportion 40 with a through bore 41 which is rectangular transverse cross section and

dimensioned to slidably accommodate upper leg portion 3. Members 27 haveflanges 42 which are parallel and spaced apart by a distance adequate to freely

accommodate one end portion of one of the brace members 28.

Leg portions 2 and 3 are pivoted to members 4 by pivot pins 43 in any suitable

manner. Members 27 are fixed to leg portions 3 by pins 44. Brace members 28 arepivoted to flanges 42 by pins 45. The upper ends of leg portions 3 are pivoted to

flanges 16 of upper clevis member 10, as by pivot pins 46. The ends of bracemembers 28 are likewise pivoted to lower clevis member 11 by pivot pins 47, Fig. 5.

It will be apparent that various changes and modifications can be made withoutdeparting from the scope of the invention as defined in the claims. Thus flanges 8,

Fig. 3, can be replaced by partitions 8', Fig. 3A and reinforcing extrusion 9, Fig. 3,

can be replaced by a filling of polymeric foam 9', Fig. 3A.
