The child safety seat includes a seat body that is attached to a base that is held in place by the vehicle seat belt. The base provides for movement of the seat body around at least one axis. A turntable allows the seat body to be rotated from a safe-riding position to face the car door to facilitate positioning the child in the seat or to make it easier to grasp and maneuver a separable child carrier with the child in it. Inadvertent rotation of the turntable is prevented by a locking mechanism that remains engaged until released by the parent or caregiver. In one embodiment, a second axis of movement allows the seat body to be reclined so that the child's head is supported when he or she falls asleep. The reclining adjustment is a motorized motion which can be remotely controlled by the parent or caregiver sitting in the front of the vehicle via wires connected to a remote control.

The invention provides a hinge device and a folding device with the hinge device. The hinge device comprises a hinge support, a first shaft and a second shaft. The first shaft and the second shaft are arranged in parallel and are rotatingly supported by the hinge support. The first shaft is connected to a first main body of a device. The second shaft is connected to a second main body of the device. Through being guided by the first shaft and the second shaft, the first main body can rotate 0 to 360 degrees and/or 360 to 0 degree relatively to the second main body. When the first main body rotates 0 degree to a preset angle and/or the preset angle to 0 degree relatively to the second main body, the first shaft rotates and the second shaft is static, and when the first main body rotates the preset angle to 360 degrees and/or 360 degrees to the preset angle relatively to the second main body, the second shaft rotates and the first shaft is static.

A collapsible buttstock with automatic deployment has a housing with an opening providing clearance for a buffer tube. Rods slidably couple through respective openings in the housing; the rods each having a hollow cavity accommodating biasing structure for exerting a biasing force against a respective attachment member. A locking element has locking blocks, each engaging a respective one of plural notches on the rods, for locking the rods to an operator support buttstock element, each of the locking blocks comprising a tapered surface. A release trigger with a contoured step engages the tapered surfaces of the locking blocks. When the release trigger is moved, the contoured step engages the tapered surfaces to push locking blocks away from engagement with the notches on the rods, thus allowing the biasing member in each rod to push the respective rod and the operator support buttstock element away from the housing.

An apparatus for fastening a product to its package for shipment and display. The apparatus includes a key having a base, an inner pad and outer ring portions. The base includes two bridges supporting two pairs of living hinges, each of the pairs being connected to an outer ring portion. The outer ring portions are enabled to pivot between a position generally aligned with the inner pad and a position generally perpendicular to the inner pad so as to act as a handle to rotate the key. The inner pad supports a post and a pair of protrusions. Between the inner pad and the outer ring portions are openings for receiving a strip of stiff paper. After the key is inserted through the package and into the product, the key is rotated to cause an abutment of the protrusions with the product to fasten the product and package together. The strip is then inserted to prevent inadvertent rotation of the key. After purchase, a consumer may easily and quickly remove the strip, rotate the key and remove it from the product and the package to enable the product to be separated from the package, and the package and the key to be disposed. Multiple keys are used with multiple strips incorporated in a stiff paper panel. Each strip takes the form of a hole in the panel flanked by two strip tabs that connect to the key inserted through the hole of the strip. A reinforcing support may be placed between the panel and the package.

A table or desk assembly (20) includes a base having a pair of legs (24), a worksurface (22) supported by and between the pair of legs, and a rapid, counterbalanced height adjustment mechanism interposed between the legs and the worksurface for providing adjustment in the elevation of the worksurface. The height adjustment mechanism includes a pair of high lead rotatable threaded rods (32) engaged with a mating stationary threaded member (33) associated with each leg. A handle (36) is engageable with one of the threaded rods for imparting rotation to the threaded rod, and a synchronizing arrangement, such as a sprocket (38) and chain system (40), is interconnected with the other of the threaded rods for rotating the threaded rods together. A lift assist or counterbalancing mechanism applies an upward bias, such as to the worksurface, to counteract the weight of the worksurface and any loads supported by the worksurface. The counterbalancing mechanism may be in the form of a cylinder assembly (54) having a biased retractable and extendible member, which is interconnected with each of the threaded rods via a cable (66) and pulley (68) arrangement. Alternatively, the lift assist or counterbalancing mechanism may be in the form of constant force spring arrangements (76), each of which has an extendible and retractable member. A retainer arrangement (90) is interposed between the crank or handle member (36) and the worksurface, for preventing inadvertent rotation of the threaded rod and thereby maintaining the elevation of the worksurface.

An anti-decoupling device for use in preventing undesired rotation of a spin coupling of, for example, a two-part electrical connector, is disclosed. The anti-decoupling device can form part of a new connector, or can be used to retrofit existing connectors without having to modify the connector. In some embodiments, the anti-decoupling device comprises a base and two prongs that extend in a generally axial direction relative to the base. Blades that depend from the prongs extend into channels within the knurled side-edge of the spin coupling. The blades prevent inadvertent rotation of the spin coupling.

The blade guard includes a sleeve portion (10) rotatably fitted on a bearing box (8) coupled to the saw blade assembly and a sectoral portion (11) extending radially from the sleeve portion in the rear of the blade. A connecting bar (13) projects radially rearward from the sectoral portion. A spring (14) is stretched between the top of the connecting bar (13) and a lower rear portion of an upper blade guard (4) close to the base plate. When not in use, torque, generated as the product of the spring's tensile force and the perpendicular distance (S) from the line of action or the force to the axis of rotation (O), rotates the blade guard to a closed position.
