Abstract: A self-closing closure for a tube or package having a resilient wall for dispensing flowable material upon the application of pressure on the tube, utilizing a relatively stiff spider for supporting an outwardly extending valve stem having a closed outer surface and a diaphragm member having its periphery interconnected with the periphery of the spider to form a closure unit and its inner portion forming a valve with the valve stem. The diaphragm member is formed with a relatively thick flange substantially parallel with the walls of the tube for interconnection therewith, a relatively thin, resilient planar portion extending inwardly toward the stem, and a substantially tubular portion surrounding the stem and terminating in an open lip which makes a close, sliding fit with the outer surface of the stem.The resilient, planar portion of the diaphragm member is normally concave, being formed with an unstressed negative angle of substantially 5.degree. to 15.degree.

Abstract: A sled frame for the releasable attachment of a wheelchair. The sled frame includes a body portion supporting a pair of laterally spaced, horizontally disposed support members which, in turn, are sized to be disposed between the wheels of a wheelchair to support the frame of the wheelchair on the sled. The support members are each provided with a plurality of locking devices which releasably engage the frame of a wheelchair to securely lock the wheelchair to the sled. The sled frame further includes a pair of laterally spaced, longitudinally disposed ski runners. A steering runner provided at the forward end of the sled is attached to a steering post that extends upwardly through the frame and rearwardly toward the wheelchair support area such that an occupant of the wheelchair may grasp the steering wheel carried at the upper extending end of the steering post to facilitate the steering of the sled.

A device is provided for positively rotating the door winding drum to effect coiling of the door thereon and, in turn, movement of the door to the open position, and a device is also provided for positively rotating the cable winding drum to effect coiling of the cable thereon and, in turn, movement of the door to the closed position.

Abstract: Two-wheeled carts can be constructed so that their bodies can be manipulated between a normal, expanded configuration in which such carts can be used and a folded, relatively compact configuration in which such carts may be easily and conveniently stored. Such foldable carts include side walls, at least one of which is constructed so as to include two panels and a hinge connecting such panels in edge-to-edge relationship. A connector pivotally connects the side walls so that they can be manipulated so as to be moved generally toward one another as the structure is manipulated from the unfolded to the folded configuration. The extremities of these side walls are connected by end walls each of which consist of two wall sections connected in edge-to-edge relationship by center edge hinges. The wall sections have side edges which are connected to the sides by side edge hinges.

Abstract: A caulking gun is disclosed comprising a handle, a ramp mounted on the handle for receiving a caulking cartridge having a nozzle thereon, the end of which has to be removed by cutting. The nozzle of the caulking gun is also sealed to a caulking cartridge by means of a ruptureable seal. An opening is provided in the handle into which the nozzle of such a caulking gun may be inserted to cut the end therefrom by means of a knife blade operably attached to a trigger used for advancing a ram to extrude caulking compound from the cartridge. The handle of the caulking gun also contains a puncturing tool retractably mounted in the handle for puncturing the seal at the base of the nozzle of the caulking cartridge.

Abstract: An attachment for protecting the hood and controls of snowmobiles from damage caused by the turning over of the vehicle which comprises a rigid, welded, cage structure extending above the steering handlebar but below the windshield. The structure is removably secured by its lower end to horizontal mounting brackets fixed on each side of the vehicle.

Abstract: A desirable emitter for use in drip irrigation can be constructed so as to utilize an elongated member formed of a flexible, resilient material so as to include at least one and preferably a number of internal ribs or projections which prevent the interior of the member from being closed off or pinched shut as it is deformed or flexed. Such a member is normally mounted so as to extend into an enclosed space such as the interior of an irrigation tube or conduit in such a manner that water can flow from the interior to the exterior of the space through the member. The liquid within the space can be controlled so as to exert a force against the exterior of the emitter causing it to be deformed or flexed in such a manner as to vary the flow through the member.

Abstract: A seat bottom and a seat back are pivotally mounted for movement between a normal seating position and a cargo floor position. A seat belt includes a strap having one end anchored on the vehicle body, a buckle attached to the other end of the strap, and a plastic stiffening boot which extends through the gap between the seat back and the seat bottom to position the buckle element in an occupant accessible position. A spring urges the boot into engagement with the seat back to establish the boot and buckle in a normal position in which the seat bottom may be pivoted between the normal seating position and the pivoted position without interference with the boot or buckle. The spring yields when the seat back is pivoted forwardly to the cargo floor position and then returns the seat belt to the normal occupant accessible position when the seat back is returned to its normal seating position.

Abstract: A stowable ladder for use on a combine is provided with a spring assisted overcentering linkage that will maintain the foldable ladder in either a deployed status or closed status until significant manual effort overcoming the spring loaded overcentering linkage is induced.

Abstract: A holder for golf clubs or similar articles is in the form of a continuous strip of flexible but resilient material fastened to a base at spaced points and bent, between those points, to define a series of adjacent loops to grip the articles between them. Each of the loops has a body of resilient foam within it to hold the loops yieldably distended. In one adaptation the holder is mounted on a golf pull cart having wheels foldable to a position where the pull cart can fit in the customary space on a motorized golf cart provided for golf bags. In another form the cart is provided with a pivoted leg for holding the cart in an upright position.

Abstract: The self-closing cap for resilient dispenser-containers to be mounted to the aperture of the neck of the dispenser, comprises a channel member having a flat member issuing from one side of the aperture, parallel to the rectilinear axis of the neck; a reed being a stiffly flexible member fastened parallel to the channel member on the aperture, the reed being mounted to be urged at its uppermost terminal end contiguously with the upper portion of the interior side of the channel member; and means for enclosing the respective sideward edges of the channel member and the reed.

Abstract: A squeeze bottle containing a liquid product, such as antiperspirant and the like, has a dispensing nozzle internally forming a swirl chamber having opposed orifices each having its own inlet. One inlet is connected with a dip tube that dips into the liquid when the bottle is upright, and the other inlet connects with an air space above the liquid when the bottle is upright. When the bottle is squeezed, the swirl chamber receives opposed jets of the liquid and air, producing an atomized spray. When the bottle is inverted, the dip tube opens into the air space formed in the bottom of the inverted bottle, while the other inlet is connected with the liquid so that again opposed liquid and air jets enter the swirl chamber.
