  • Patent number: 6854138
    Abstract: A rocking crib or cradle having a motion inducing mechanism with automatic lock. The motion inducing mechanism imparts a movement to a movable portion of the crib or cradle in relation to a longitudinal base while the lock immobilizes the movable portion in relation to the base. Operation of both the motion inducing mechanism and lock are related to one another with a timer such that the lock automatically immobilizes the movable portion of the crib when the time duration of the motion inducing mechanism is expended. A time delay switch may be connected between the timer and lock to delay operation of the lock for a preset time after the expiration of the time duration of the motion inducing mechanism. A handle may be connected to the lock to manually operate the lock to immobilize or free the movable portion of the crib in relation to the longitudinal base, such manual operation energizing or de-energizing the timer and motion inducing device accordingly.

  • Patent number: 6470516
    Abstract: A portable double level cradle rocking bassinet including a standard bassinet onto which is formed lower fixed rockers and also formed elongated foldout rockers. The bassinet has a frame portion to which are attached the lower fixed rockers on either end of the frame portion. When the bassinet is to be rocked, the individual simply unfolds the bassinet to the open condition, places the baby in the frame portion and then rocks the bassinet back and forth on the lower fixed rockers at a ground level. The bassinet also has foldout rockers which can be unfolded to the extended condition, so that the bassinet can be rocked back and forth at a bed or chair level. The foldout rockers can be stored by folding upwardly against the underside of the frame portion and are retained thereto by mating fasteners.

  • Patent number: 5956786
    Abstract: The present application provides an improved playpen that can be transformed into a rocking cradle. The playpen becomes a rocking cradle due to pivoting arcuate tubes fitted to a bottom of the playpen. Therefore, it is easier for the parents to coax infant to sleep comfortably in that type of the playpen. More importantly, the arcuate tubes can readily be pivoted to their first configuration whereby the rocking cradle is converted back into the conventional playpen.

  • Patent number: 5702496
    Abstract: A shaped glass sheet having a sharp bend is provided, wherein a radius of curvature of an outer circumference of the bend transverse to the bend is at most 4 times a thickness of the glass sheet and the straight sections of the shaped glass sheet are substantially flat. A process for the preparation of the shaped glass sheet comprises applying an electrically conductive material on a surface of a glass sheet to form a bend line, generating a graded temperature profile transverse the bend line, and then applying an electrical potential to the bend line. In another process, a width or thickness of a bend line is not uniform or a bend line is discontinuous in the longitudinal direction of the bend line, no particular temperature profile is required and, upon applying an electrical potential, arc discharge occurs along the bend line to melt the glass rapidly.

  • Patent number: 5533936
    Abstract: An infant swing assembly has a stabilizer for immobilizing the seat during placement of a child therein and removal therefrom. The stabilizer has at least one connector, preferably a pair of collinearly spaced ring connectors, for pivotally attaching to the hanger of the swing assembly. The stabilizer has an engaging portion, preferably a hook which can be engaged with the leg of the swing assembly to immobilize the seat. The stabilizer can be pivoted downward and positioned adjacent the side of the seat where the stabilizer cannot engage with the leg thus permitting the seat to freely swing and laterally outwardly where the stabilizer is able to engage with the leg.

  • Patent number: 4783863
    Abstract: A pendulum frame (2) is suspended on a fixed stand (1) by means of four pendulums (16). The amplitude of each of the pendulums (16, 17) is limited by a plate (24) provided with an orifice (23). The plates (24) carry locking projections (28), into which detent pawls (26), arranged on the pendulum frame (2) can engage. When only one of these detent pawls (26) is in the locking position, the bedding furniture can swing about this detent pawl which functions as a pivot pin. When two detent pawls (26) located behind one another in the longitudinal direction of the bedding furniture are locked, the pendulum frame (2) is blocked and is held outside its mid-position on one side. A free-swinging mid-position, four pendulum positions locked at one point and two fixing positions locked off-center are therefore available for each piece of bedding furniture.The bedding furniture can be adapted to meet individual sleeping requirements and is also characterized in that bed care becomes considerably easier.
