A connecting apparatus includes a main body having a first half member and a second half member; the second ends of the two half members configured to open or close relatively to each other; an accommodating cavity formed between the first and second half members; a driving member and an actuating member installed inside the accommodating cavity; the driving member capable of driving the actuating member to move toward the second ends of the two half members to an opened position, thereby expanding the second ends of the two half members outward. The connecting apparatus is installed inside an elongated member, and latch portions on the second ends of the two half members are able to latch onto another elongated member to achieve a connection between elongated members.

Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.

A watercraft includes a plurality of separable body sections (2101, 2102, 2103, 2104, 2105, 2106) configured for assembly into a single assembled structure (2100) having a first length, and for packing into a packed structure (3000) having a second length smaller than the first length. The single assembled structure may be held together using latching devices, one or more of the latching devices including a latch unit comprising a latch support, a spring mount and a band spring, the band spring having a first spring end and a second spring end, wherein the latch support includes a latch and a first shaft positioned in relationship to the latch, the first shaft configured for rotatably mounting the first spring end of the band spring, and the spring mount includes a second shaft configured for rotatably mounting the second spring end of the band spring.

A quick release mechanism includes a fixed component, a first assembly, and a second assembly. The fixed component has a guiding portion and a first positioner. The first assembly includes an engagement component and a return component. The engagement component is pivotably disposed on the fixed component and includes a first protrusion part, a first press part, and a second positioner. The return component keeps the engagement component in an engaged position. The second assembly is removably inserted into the guiding portion. The second assembly includes a second protrusion part and a contact part. The engagement component is movable away from the engaged position by abutting of the second protrusion part on the first protrusion part or by abutting of the contact part on the first press part during insertion of the second assembly into the guiding portion.

A chassis node coupling system includes a chassis node configured to be received at a first end of a chassis assembly, wherein the chassis node size exceeds the chassis assembly size. A latch assembly with one or more coupling assemblies may be configured to releasably couple the chassis node to the chassis assembly.

A hand crank cam lock for connecting medium to large sized display walls or boards including a hand crank disposed in a cam lock. The hand crank cam lock is configured to join two separate extrusions or frames together in a toolless manner. The hand crank cam lock locks these frames when the hand crank is turned clockwise, a plurality of hooks slide back along channels inside an outer body to grab the inner walls of a frame. This will in turn lock the hooks into place against the inner walls. The hand crank will only require half a turn to travel the required distance to lock the hooks into place and this half turn may be performed via a tool or by hand.

Clamping arrangements for assembling components of modular furniture are disclosed. The clamping arrangements can include a frame comprising a cavity intermediate opposing sidewall surfaces. The clamping arrangements can also include a spring positioned in the cavity, wherein the spring comprises a folded metal sheet. The clamping arrangements can also include a lever comprising a camming surface, wherein the lever is pivotably coupled to the first sidewall and the second sidewall about an axis of rotation and pivotable between an unclamped position and a clamped position. The camming surface can be configured to directly engage the spring and deform the spring to a clamping configuration when the lever is in the clamped position.
