Abstract: A safety device for a foldable baby bed has a pivotal block fitted to one of pivotally connected base rods of the bed, and a locking member fitted to another of the base rods. A tube is pivoted to the pivotal block at a first end; the tube has a down facing cavity at a second end. The tube is movably passed through the locking member from the second end so that the cavity can fit onto a protrusion of the locking member when the bed is stretched to an in-use position where the base rods are positioned substantially on a plane; thus, the safety device prevents folding of the bed caused by unexpected force. The cavity is disengaged from the protrusion for allowing displacement of the base rods by means of lifting the second end of the tube.

Abstract: A buckle for an infant carrying band includes a base shell having a hollow chamber inside and a through hole provided on the front surface, communicating with the chamber. A curved engage member is fitted in the chamber and has its press member protruding out of the base shell through the through hole. The engage member has two clasps respectively provided at the opposite ends for clasping the couplings connected with an infant's carrying bands. Thus, the curved engage member is fitted in the chamber of the base shell, having proper resilience, and then two couplings are respectively clasped by the clasps at the opposite ends of the base shell. To disengage the couplings from the clasps, only press down the press member of the curved engage member.

Abstract: A supporting device for a front wheel of a stroller includes a locking member, a supporting member and a control member. The locking member is received in two aligned cylindrical parts of the supporting member, and has two protruding parts at upper portions of two resilient upright poles thereof; the protruding parts face a gap between the aligned cylindrical parts. The control member is pivoted to the supporting member, and has a locating part facing the gap of the supporting member. The supporting device is separably connected to a support tube of the stroller frame with the cylindrical parts being passed around the tube and the poles being passed into the tube; the protruding parts stick out through opposing lateral holes of the tube into the gap to prevent the tube and the supporting device from separating from each other.

Abstract: A joint for a playen has a main base, two plate hooks, two wing bases and a press block. The wing bases are pivoted to the main base, and each connected to a support rod of the playen. The plate hooks are fixed to the press block, and each has two end barbs. The press block is movably connected to the main base with a guide pin passed through two aligned shaped holes of the main base; the guide pin is also passed through a long vertical hole of the press block. The joint is spread at an unfolded position with locating pins of the wing bases engaging the barbs of the plate hooks. To fold the joint, the wing bases is pivoted inwardly of the main base, and the press block is pushed up to disengage the locating pins from the barbs; the guide pin can move in the shaped hole sideways to permit the press block to move sideways, helping the barbs separate from the locating pins of the wing bases easily.

Abstract: A direction changing device for a handle of a stroller comprises a main body, a pulling rod and a co-moving part; the handle is fixed to the main body, which is capable of pivoting on a fixing element of a support member of the stroller. The main body has a hollow, in which the co-moving part is movably received. The pulling rod has a hooked end engaging a slope of the co-moving part. The co-moving part has two concavities each communicating with a confining end of the hollow to form two locating holes for a locating pole of the support member to be passed thereinto. The locating pole engages either one of the concavities to prevent the main body from turning. When the pulling rod is pulled, the co-moving part will be moved further into the hollow for releasing the concavities from the engagement with the locating pole. Thus, the main body plus the handle can be pivoted to change direction of the handle.
