Abstract:
A supporting frame for a golf bag, comprising:a head bracket attached to a top of a receiving bag of said golf bag, a supporting board, a linking rod, a linking rod top cover and a linking rod lower base, a transmission block, a pair of guiding shafts, a pair of springs, a pair of connecting rods, a pair of coupling sleeves and a pair of supporting legs; wherein: said head bracket is secured to a top opening of said receiving bag; at a back of the periphery of said head bracket is equipped with a pair of symmetrically disposed hollow housing projectors each of which has a plurality of spaced retaining units at a top edge thereof; in said head bracket are disposed a plurality of partitioned spaces for housing golf clubs; at a rear internal surface of said head bracket is defined a corrugated receiving room for housing said corrugated supporting board having an extended coupling piece with a pair of tubular screw holes at the top edge thereof, at a top edge of said receiving room are disposed a pair of locking holes for securing said supporting board in place by screws; a shaft housing tube is disposed at each end of said corrugated wall of said receiving room; on a rear side of said receiving bag are disposed a pair of vertical splits adjacent to a top so as to permit said connecting rods to be partially exposed; and a slant flat section at the bottom thereof, a dodge cavity defined in the vicinity of said slant flat section has a central through hole at the top thereof; said linking rod has a triangular supporting base outwardly bent at a bottom end and an axially extended locking hole at a top end thereof; said top cover attached to said triangular supporting base of said linking rod has a cover block terminating in a vertical connecting tube with a plurality of locking studs disposed thereunder; said lower base is integrally secured to said top cover with said triangular base sandwiched therebetween; said transmission block has a central engaging column for engaging with said linking rod and a pair of symmetric side inserting columns for locating said guiding shafts; at the top of each said side inserting column is disposed a horizontally projected pivot pin; each said connecting rod is in pivot engagement with said transmission block by said projected pivot pin at one end and is in pivotal connection to each coupling sleeve at another end; each said spring is attached to the top of each said guiding shaft respectively; each coupling sleeve is secured to a top end of each supporting leg and is in pivotal engagement with said head bracket; and to the top end thereof is secured a retaining head which has a lateral pivot hole, a relief positioning rib and a collection positioning rib; each said supporting leg has a top end engaged with said coupling sleeve so as to permit said supporting leg to be pivotally extended with respect to said receiving bag; whereby said coupling sleeves and said supporting legs are securely engaged with each other; and said coupling sleeves are further in pivotal engagement with said housing projectors of said head bracket attached to the top of said receiving bag; said guiding shafts are fixed in place to said head bracket; and said coupling sleeves are further in pivotal connection to said transmission block by said connecting rods; and said linking rod is fixed to said transmission block which is limited to slide up and down along said guiding shafts by said springs confined between said transmission block and said guiding shafts as said triangular base covered by said top cover and said lower base of said linking rod is in contact with a ground so as to permit said transmission block to slide up and down by way of said springs, resulting in the extension or collection of said supporting legs and said connecting rods automatically away or toward said receiving bag accordingly when said receiving bag is tilted one side or placed in a vertical position.
