Abstract: Tent couplers include a pivot interlocking member and a bridged interlocking member. The bridged interlocking member comprises a bridge that extends between a tether-receiving portion and a tent support-receiving portion that includes a tent support receiver configured to couple to a tent support. The pivot interlocking member includes a tent fabric receiver configured to couple to a tent fabric. The pivot interlocking member defines a bridge-receiving aperture and an entrance slot interconnected thereto. Tent couplers are selectively configured between a linking configuration and an interlocked configuration. In the linking configuration, the pivot interlocking member is positioned for insertion and removal of the bridge from the bridge-receiving aperture via the entrance slot.

Abstract: The tents include a tent frame and an outer tent fabric. The tent frame forms an assembled tent frame defining a base and is configured to support the outer tent fabric above the base. The outer tent fabric is configured to be supported by the assembled tent frame to surround an inner space that interfaces the base of the assembled tent frame. The tent is assembled when the outer tent fabric is operably supported by the assembled tent frame, and the assembled tent is configured to interconvert between a shelter configuration and a canopy configuration. In the shelter configuration, the base of the assembled tent frame extends along the support surface. In the canopy configuration, the base of the assembled tent frame is inclined relative to the support surface. Tents further include a lift coupler configured to interconnect the assembled tent with a tent-elevating support in the canopy configuration.

Abstract: An improved valve for an inflatable device includes a valve port received within an aperture of the inflatable device, a valve seat having fluid apertures provided therein, and a diaphragm connected to the valve seat in a manner that occludes the fluid apertures when fluid is not forced therethrough. The improved valve may, at any time, be manipulated so as to physically remove the valve seat from the valve port to facilitate deflation of the inflatable device and physically insert the valve seat into the valve port to facilitate inflation of the inflatable device.

Abstract: A cart is provided for a watercraft including at least two apertures provided therein. the cart includes a transportation portion, and a carrying portion. The carrying portion includes at least two vertical shafts protruding from the transportation portion. The protruding end of each shaft is connected to, or received within, a watercraft engaging portion that tapers off in size as it extends further away from the transportation portion such that at least a section of each watercraft engaging portion deforms and compresses when received within one of the at least two apertures to create frictional engagement between the aperture and the section of the watercraft engaging portion.

Abstract: A cart is provided for a watercraft including at least two apertures provided therein. The cart includes a transportation portion, and a carrying portion. The carrying portion includes at least two vertical shafts protruding from the transportation portion. A watercraft engaging portion is formed around at least a portion of each vertical shaft. When received within one of the at least two apertures, at least a portion of the watercraft engaging portion compresses to create a frictional engagement between the watercraft and the cart.

Abstract: A collapsible container includes a compressive wall and a base. The base includes a retaining ring extending from at least a portion of its circumference, and the base is also made of a hardened material compared to the material making up the compressive wall. The compressive wall is adapted to be retained around the circumference of the base via the retaining ring.

Abstract: A compact hand tool comprising an operating portion terminating in a collar and a handle portion adapted to be received within the collar. The handle portion is operable to be securely retained in a first position where the hand tool may be used to perform its normal function as determined by the operating portion. The handle portion is slidably movable to a second position where the handle portion overlays the operating portion to facilitate storage of the hand tool. The hand tool is made of a substantially light-weight material.

Abstract: A profilometer having a beam placement system which includes a beam pivotally connected to a front and a rear foot member. The foot members are spaced along the length of the beam and are arranged to be positioned on a section of pavement. The beam placement system also includes a system for repositioning the front and rear foot members so that, upon forward movement of the profilometer along the pavement whose profile is to be measured, the rear foot member is positioned on the section of pavement previously occupied by the front foot member. The beam placement system additionally includes an apparatus for measuring the slope of the beam between the front and rear foot members.
