Abstract: A foldable basketball game assembly includes a base, an extendable upright frame connected to an end of the base and an extendable end frame connected to the other end of the base. A board is connected to the upper section of the upright frame and a sound producing member is connected to the board. A hoop is pivotably connected to the sound producing member and a sensor extended from the sound producing member is located in a center of the loop so that when a ball enters the hoop, a pre-set sound is produced.

Abstract: A rock climbing device includes two rails each have a slot and a front shaft is positioned between the two rails by engaging with a positioning device in the slots. A rear shaft is fixed connected between the two rails. Two pairs of bars are pivotably connected to a top shaft at one end thereof and the other end of the bars are respectively connected to the front shaft and the, rear shaft. A circular surface member is movably mounted to the front shaft, the rear shaft and the top frame. A plurality of grasp members are removably connected to the surface member and a driving device circulates the surface member.

Abstract: A home plate includes a pentagonal body and a plurality of marks are marked on a top surface of the body. The body has a tapered top surface so that the pitcher can see the marks on the top surface clearly. A line is connected to the body and at least one positioning member is connected to the line so as to indicate the position of the pitcher's rubber.

Abstract: A foldable basketball frame assembly includes a backboard having four flanges extending from four sides of the backboard and a cover is connected to the bottom flange of the backboard. A ring is connected to the top flange. A first transverse bar is connected to the flange on the lower end of the backboard and two two-way connection members are respectively connected to two ends of the first transverse bar. Two foldable siderails are respectively connected the two two-way connection members and a three-way connection member is connected to a distal end of each siderail. A second transverse bar is connected between the two three-way connection members. Two legs are respectively connected to the three-way connection members. All the parts of the assembly can be folded and received in a bag formed by connecting the cover to the flanges on four sides of the backboard.

Abstract: A baseball bat includes a hollow bat and an aperture is defined in an end of a barrel of the bat. A flange extends radially inward from an inner periphery of the bat and a rod movably extends through the flange. A spring is mounted to the rod and biased between the flange and a skirt on the rod. A hook is pivotally connected to the inner periphery of the bat and engaged with a groove defined in an outside of the skirt. A rope extends from the hook and passes from a hole defined through the bat. A trigger is connected to the rope so that when pulling the rope, the hook is disengaged from the groove and the rod jumps to throw a ball in the aperture from the end of the barrel.

Abstract: A goal assembly includes two lengthwise assemblies and two L-shaped assemblies which are pivotally connected between the two lengthwise assemblies which are parallel with each other on different horizontal planes. Each lengthwise assembly has two sections pivotally connected by a connection member. Each L-shaped assembly includes a post and a widthwise bar pivotally connected with each other. A net is connected to the two lengthwise assemblies and the two L-shaped assemblies.
