Abstract
A portable and collapsible stadium seat comprises a seat bottom support, a back support, and a safety latch for properly positioning the seat in place relative to a stadium bleacher seating surface or bench. The seat bottom support and back support are interconnected for movement between an operative, or set-up, condition defining a seating surface and a back support surface, and a collapsed, or bundled, condition designed for easy transport and storage of the seat. The safety latch is movably connected on underside of the seat bottom support, preferably towards the forward end thereof, and provides a stop and an arm facilitating proper and safe positioning of the seat on a bleacher or bench surface for use. The seat preferably includes a carrying strap or handle for transporting the collapsed and bundled seat, for example, over the user's shoulder or via a hand grasp.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
(29) Turning now to the drawings, a portable and collapsible stadium seat embodying the present invention, generally designated by reference numeral 10, is shown in
(30) The seat 10 generally comprises a seat bottom support 12 and a back support 14 interconnected together for movement between the set-up and collapsed conditions. As shown in
(31) As further shown in
(32) As shown in
(33) Various materials and construction methods may be employed in making the foldable stadium seat 10 of the present invention. However, in accordance with presently preferred embodiments, the seat bottom frame 18 and the back support frame 20 are formed from durable lightweight tubular metal. As illustrated in
(34) As best shown in
(35) The back support frame 20 comprises a generally U-shaped tubular back frame member similar to the seat bottom frame member and includes a pair of back side members 44 integrally connected at their respective upper ends by a transverse upper connecting member 46. This upper connecting member 46 can be arched backwards, as illustrated in
(36) As noted, the back support 14 of the seat 10 is pivotally disposed relative to the seat bottom support 12. In the operative set-up condition of the seat 10, the back support 14 extends generally upwardly from a rear portion or edge of the seat bottom support 12 and is capable of pivotal movement relative to the seat bottom support 12 for collapsing the seat 10 to its collapsed condition. As previously noted, a set-up condition of the seat 10 is illustrated in
(37) Referring to
(38) As illustrated, for example, in
(39) In a preferred embodiment, the first stop 52 projects downwardly from the seat bottom frame 18 beyond the support plane of the seating and support frames. In this regard, if the seat 10 is placed on the bleacher surface 200 too far back, the first stop 52 will inhibit the seat 10 from sitting flush on the bleacher 200, as illustrated in
(40) Referring to
(41) Referring to
(42) In
(43) Referring to
(44) In this alternate embodiment, the armrests 26 from the preferred embodiment are replaced with a strap 160 wrapped around the back support 114 of the seat 110 in the set-up condition. This strap 160 is similar to the strap design shown and described in Applicant's U.S. Pat. No. 5,779,314, entitled Collapsible Multi-Purpose Chair, which is incorporated herein by reference in its entirety. When the seat 110 is in a folded and collapsed condition, the strap 160 is relaxed and can be used as a carrying strap, such as like a shoulder strap, to easily transport the collapsed seat 110. When the seat 110 is in its set-up or operative condition, as it appears in
(45) In a preferred embodiment, the strap 160 preferably comprises an assembly of two parts joined by a suitable adjustable fastener or buckle 162. The end portions of the strap assembly are respectively connected to opposite lateral sides of the seat bottom frame 118 by pivot pins 164. The strap 160 is then wrapped around the back support 114 when the seat 110 is in its set-up condition. The buckle 162 is preferably located in a readily accessible position at the side of the seat 110. A person seated in the seat 110 may adjust the angular position and tension of the back support 114 of the seat 110 from a seated position by releasing the buckle 162 and pulling in on or letting out the free end of a strap 160 to change the angular position of the back support 114 relative to the seat bottom support 112.
(46)
(47) When the seat 110 is resting on a seating surface (e.g., bleacher bench 200) in its set-up condition, it may be automatically collapsed to its collapsed condition by grasping a central portion of the strap 160 at the rear of the back support 114 and applying a lifting force to the strap 160 to move it to its carrying condition. When the seat 110 is lifted by the strap 160, the weight of the seat 110 borne by the strap 160 causes the seat bottom support 112, where the ends of the strap 160 are connected, to be pulled toward the back support 114. Thus, as the seat 110 is brought to a shoulder carrying position, it is automatically collapsed into a compact bundle, which may be easily supported and transported on the shoulder via the strap 160. Moreover, the weight of the seat 110 acting upon the strap 160 maintains the seat 110 in this compact bundle as long as it remains in a carrying condition. The seat 110 may be rapidly deployed from such a carrying condition to its set-up condition by reversing the motions generally afore-described. That is, when the seat 110 is unslung from the user's shoulder and grounded, the seat 110 may be readily opened by releasing the strap 160 and grasping the upper portion of the back support 114 and moving the back support 114 to a preferred position relative to the seat bottom support 112 to define a seating accommodation for the user.
(48) The carrying strap 160 may also be used in a design of the stadium seat having armrests 26 without departing from the spirit and principles of the present invention.
(49) The foregoing description of embodiments of the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the form disclosed. Obvious modifications and variations are possible in light of the above disclosure. The embodiments described were chosen to best illustrate the principles of the invention and practical applications thereof to enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as suited to the particular use contemplated.
