Abstract: The present disclosure generally relates to the field of medical devices for treatment and diagnosis of paranasal sinus conditions and methods of using same. There is disclosed a device having a hollow shaft configured to be inserted into a paranasal sinus through a natural opening thereof. The hollow shaft is shaped/configured to reach a treatment area within the paranasal sinus.

Abstract: A system for axial coupling a first member with a second member is provided. The first member comprises a polygonal locking neck telescopingly receiving a polygonal portion of the second member. An inside wall of the locking neck comprises at least one arresting member and an angular locking member, configured for selectively arresting the angular arresting member and retaining the second member at a locked position. An inside face of the polygonal portion of the second member comprises a flat face portion and an arresting portion extending at a reflex angle with respect to the flat face portion, and a plurality of locking teeth disposed along the arresting portion, each configured for engaging with the at least one arresting member. The flat face portion is partitioned from the arresting portion by an axially extending angular arresting member configured for arresting by the locking member.

Abstract: A container comprises a cover member and a receptacle member axially displaceable therewithin for selective axial arresting therewith. A polygonal locking neck of the cover member telescopingly receives a polygonal portion of the receptacle member. A circumcircle of the polygonal portion is smaller than an inscribed circle of the polygonal locking neck. The polygonal portion of the receptacle member can be reciprocated about a longitudinal axis between a locked position at which an arresting member is engaged with locking teeth of the receptacle member, and an unlocked position at which the at least one arresting member is disengaged from the locking teeth of the receptacle member. Twisting of the cover member and the receptacle member at opposite senses results in disengaging the locking teeth of the receptacle member from the at least one arresting member of the cover member, into the unlocked position.

Abstract: A pallet-dolly device convertible between a pallet and a dolly has a deck to which a set of dolly wheels are attached at a fixed height below the deck. A set of movable pallet skids are mechanically interlinked with the deck by a bistable skid displacement mechanism which assumes a first state biasing the pallet skids upwards towards a skid raised position and a second state in which the bistable skid displacement mechanism biases the pallet skids downwards towards a skid lowered position. Also described are embodiments allowing conversion from dolly to pallet by directly pressing downwards on a skid, and provision of a braked-dolly state through downward pressure of the skid against the ground and/or a skid-actuated wheel brake.

Abstract: A pallet-dolly device convertible between a pallet and a dolly has a generally rectangular deck to which a set of dolly wheels are attached at a fixed height below the deck. A set of movable pallet skids are moved by a skid displacement mechanism between a skid lowered position in which a ground contacting surface of the skid is lowered below a contact plane of the wheels to provide a pallet state of the pallet-dolly device, and a skid raised position in which the skid ground contacting surface is raised above the wheel contact plane to provide a dolly state of the pallet-dolly device. At least two pedals, accessible from two adjacent sides of the deck, are deployed to be operated by a user to activate the skid displacement mechanism.

Abstract: A dolly or pallet equipped with an elastically suspended load-bearing surface so as to responsively move downwards as materials are loaded and move upwards as loads are removed thereby reducing variation in the height of the top of the stack. The elastic suspension elements are connected to suspension support structures configured to fold into a compact folded position to facilitate storage and return transport and to unfold into a fully erected position at the time of use.

Abstract: A container (10, 30) has a floor (20) for supporting produce suspended via elastic suspension elements (22) from the walls (12, 14, 16, 18) of the container so as to automatically adjust the height of the floor, and hence of the produce, as a function of the weight of the produce within the container. Optionally, an adjustment mechanism (32) is provided to allow adjustment of an effective length of the elastic suspension elements (22).

Abstract: The dolly-pallet of the present invention includes a load bearing deck that may be alternately supported by the retractable support skid or the wheel elements. Initial displacement of the skid during the retraction process is along an upward substantially vertical path. Once the retractable support skid is retracted such that the dolly-pallet is being supported by the wheel elements, the retractable support skid may be further displaced along an upward substantially arcuate path so as to move it away form the wheel elements, allowing them to swivel if they are so configured. In this way, the center of mass of the load is lowered vertically, thereby reducing stress on the displacement mechanism until the load is supported by the wheel elements.

Abstract: A foldable crate has two pairs of folding sides hinged to base. A fastening mechanism associated with one pair of sides has a pair of displaceable catch elements assuming an engagement position for engaging features of the adjacent first pair of sides to inhibit folding of the crate. The fastening mechanism also includes a manually operable actuator linked to each of the pair of catches by a mechanical linkage such that, when the manually operable actuator is displaced from an initial position in either of an upward vertical motion and a downward vertical motion, the mechanical linkages displace the catch elements from the engagement position to release the engagement so as to allow folding of the crate.

Abstract: A knock-down crate has a base and four sides detachably engageable with the base for deployment parallel to the length and breadth of the base. The upper surface of the base has an elongated recess extending most of the length and sized for receiving the sides. The sides can be engaged with the base to form a four-sided crate with the recess of the base contributing to the available volume of the crate. When not in use, the sides are received within the recess in the base for compact transportation.
