Abstract: A locking device for a rear wheel of a golf cart includes a control member disposed close to the handle of the golf cart, and a locking member disposed close to the inner side of one of a pair of rear wheels. The rear wheel is free to move when a detaining element engages with a movable element for the same to be away from the opening of a housing, thus causing a retreat of an engaging rod to a receiving hole. The rear wheel is locked at an immobile position, when the detaining element disengages from the movable element so as to allow the engaging rod to stick out to engage radially arranged protrusions on the inner side of the rear wheel.
Abstract: A foldable golf cart includes a main support rod, a pair of wheel support rods, a connecting members, two connecting rods and a handle. The wheel support rods are pivoted to an intermediate portion of the main support rod, and each connected to a wheel. The connecting member is connected to an upper end of the main support rod. The handle is pivoted to an upper end portion of the main support rod. The connecting rods are each pivoted to the handle from one end, and pivoted to a respective one of the wheel support rods from other end. The handle has hooked portions separately engaging a depressing block of the connecting member. The handle is pivoted down to a folded position; thus, the connecting rods will at the same time move the wheel support rod to a folded position. The handle is pivoted upwards to an upright unfolded position; thus, the connecting rods will move the wheel support rods to an unfolded position.
Abstract: A golf bag capable of raising golf clubs received therein is provided. The golf bag has a bottom part having a front flat portion and a rear slope portion. The rear slope portion has two holding tubes projecting into said golf bag. The holding tubes each has a sliding member movably received therein. The sliding members each has a raising block passed through a lengthwise arranged guide slot of a respective one of the holding tubes. The sliding members have lower ends contacting a first raising plate pivoted on the bottom part. A second raising plate is movably received in the golf bag with a bottom resting on the raising blocks of the sliding members. The second raising plate has holes for the holding tubes to be passed therethrough. When the golf bag is supported on the ground in a sloping position with the rear slope portion of the bottom part resting on the first resting plate, the first raising plate will force the sliding members to move upwards.
Abstract: A support of a golf cartwheel has a holding member, an axle and a curved fastening plate. The axle has an outer end connected to the wheel, and an inner end passed into the holding member. The inner end has two square blocks each received in a respective square part of the holding member. The axle further has an intermediate rod portion between the square blocks. The curved fastening plate is resilient, and is pivoted on the holding member. The curved fastening plate has a curved protrusion and a curved portion. The curved fastening plate can be secured in a closed position where the curved protrusion engages the axle rod portion with the curved portion contacting the axle rod portion, and the fastening plate is inserted into between, and secured by the square parts of the holding member in order to prevent the axle from separating from the holding member.
Abstract: A scoreboard for attachment to a golf trolley comprises an adjustment member and a holding member. The holding member is pivoted on the adjustment member. An adjustable pulling rod is movably passed through the adjustment member and urged by a spring. The pulling rod has a pulling part and engaging protrusions spaced apart on a rod portion opposite the pulling part. The holding member has confining parts and confining gaps on bottom. When the engaging protrusions engage the confining gaps, the holding member is located on a not-in-use position. And when the protrusions engage the confining parts, the holding member is located on an in-use position where the holding member forms a proper angle with the supporting shaft of the trolley. The adjustable pulling rod is pulled from the pulling part for disengaging the protrusions, and for permitting the holding member to be pivoted on the adjustment member.
Abstract: A swift wheel locking device for a golf cart includes a wheel axle and a bracket member. The wheel axle has a small diameter portion with an annular groove for a locking member to lock or unlock the wheel axle with a solid portion of the bracket member by means of a control member movably fitted in and on the solid portion and extending a little out of a cap covering on the solid portion and keeping the locking member and the control member in place in and on the bracket member. A press portion of the control member extending out of the cap can be pressed to lock and unlock swiftly the locking member with and from the wheel axle.
