  • Patent number: 5761755
    Abstract: A crib having a number of upper rods, lower rods and poles securely connected therebetween. The crib is further provided with foldable devices each pivotally connected between two distal ends of the upper rods, plates each pivotally receiving the other two distal ends of said upper rods and securely receiving a distal end of the pole, seats each securely receiving the other end of the pole and pivotally receiving two distal ends of the lower rods, pivoting blocks each pivotally receiving the other two distal ends of said lower rods and a cover enclosing all of the upper rods, the poles and the lower rods and provided with a handle disposed thereon, such that a user is able to fold the crib by lifting upward the handle of the cover after the foldable devices are activated by the user.

  • Patent number: 5704164
    Abstract: A foldable fence for confining babies includes a plurality of first supporting means, second supporting means, folding means, multiple tubes and supporting rods. The tubes each further have a mid-section with an eccentric member enclosed therein, so that when using the mid-section to extend the length of the tube is completed, turning the tube will make the eccentric member abut a peripheral side wall of the tube and therefore the length of the tube is fixed. The second supporting means provides a clearance for a rivet to move back and forth, so that when the second means abuts against a surface, such as a wall, a resilient member will provide a resilient force to further stabilize the abutting to the wall. The folding means connected between two supporting rods provides a folding mechanism to the foldable fence constructed in accordance with the present invention, such that the foldable fence is folded together to minimize the size when the use of the fence is finished.

  • Patent number: 5699997
    Abstract: A connection device for a playyard consists of a handle and two connectors. The handle is provided integrally with a block and a plurality of protrusions having a hole therein. A pair of connectors is each provided with a plurality of spaces for receiving supports and a projecting portion having a pin stably secured therein or pivotally connected with the protrusion. When the handle is connected with the connectors by a fastener, and a holding portion is in horizontal position, the connectors are not able to be folded because of the restriction of the block within two stops of the connectors, and when the holding portion is in vertical position, two connectors are able to be folded together.

  • Patent number: 5676386
    Abstract: A safety seat assembly is assembled with a stroller. The safety seat assembly includes a base member having two ears each formed on one end portion thereof and each having a notch laterally defined therein for receiving a bar of the armrest of the stroller therein. A retaining block is formed on the base member and located between the two ears. A passage is defined in and a boss is formed on an inner wall of the retaining block. A sliding lever is slidably mounted on the retaining block. A flange portion is formed on a mediate portion of the sliding lever and is slidably mounted in the passage. A stub is formed on the flange portion. A stop is formed on one end portion of the sliding lever and is detachably received in a recess of the bar of the armrest of the stroller. A biasing member is mounted in the passage and has a first distal end fixedly attached to the boss and a second distal end fixedly attached to the stub.
