Abstract: An automatically collapsible prop for propping a golf bag or the like is provided and includes a frame having a top and bottom part. A rack member is fixedly attached to the top part and includes a central guide rail formed between two side tooth members having a number of elongated parallel teeth. A slide mechanism includes a support part guided by the guide rail and a pair of pinion supports. Two pinions are rotatably mounted on the respective pinion supports of the slide mechanism so as to engage the respective side teeth. Two legs are respectively connected to the pinions. A lever rod is fastened to the slide mechanism with one end projecting upward through the support part of the slide mechanism. A coil spring is provided between the support part of the slide mechanism and the top part to normally push the slide mechanism downward.

Abstract: Disclosed is a head cover assembly for holding and protecting the heads of golf clubs from colliding with each other in a golf bag having a top and a bottom shaping part fastened to a frame. It comprises a plurality of elastic head covers for respectively covering the heads of golf clubs. A rigid head cover holder is fastened to the inside of the top bottom shaping part for fixedly holding the head covers arranged at suitable intervals. The heads are respectively and fixedly held by the elastic head covers to make at least the heads substantially immovable in the golf bag under carriage.

Abstract: An automatically collapsible prop for propping all kinds of loads such as golf bag, knapsack, coolie rack, etc., comprises a first tubular member having an upper end and an open lower end, a second tubular member relatively moveably inserted in the first tubular member so as to slide down by gravity relative to it to protrude from the open lower end of the first tubular member by a predetermined length when lifting the first member in a sloping or vertical position, and a third member rotationally mounted on a fixed shaft attached to the second tubular member so as to pivot relative to the first and second members about the fixed shaft. A first engaging groove is formed in the surface of the first member in the longitudinal direction to allow the second member with the third member to slide relative to the first member.
