DESCRIPTION:
BRIEF SUMMARY
The present invention refers to a golf bag unit having extendable and retractable travelling wheels and comprising a tubular body, which extends centrally in longitudinal direction of the bag and which adjacent its upper end carries a mounting device, a pair of support legs, pivotally attached to said mounting device and at their free ends each carrying a travelling wheel, a bag of flexible material, which surrounds the tubular body in substantially coaxial and radially spaced relationship and in the bottom of which is mounted a support plate, upon which golf clubs standing in the bag can rest, a pair of link arms, each being pivotally connected at one end with one of the support legs at an intermediate position thereof and at its other end pivotally connected with an actuation sleeve member, which is slidably movable on the tubular body, a compression spring, which is mounted within the tubular body and through at least one entrainment device, which is slidably guided in an elongated slot in the wall of the tubular body, is connected at one end with said actuation sleeve member and at its other end with the lower portion of the tubular body, a tubular control rod, which is concentrically and slidably arranged within the tubular body and at one end connected with the upper end of said compression spring and with its opposite end extending beyond the end of the tubular body in order to provide for a manual compression of the compression spring during simultaneous retraction of the wheel-carrying support legs towards the tubular body and a subsequent automatic extension of said legs to the travelling position under the utilization of the energy thus stored in the compression spring, the bag furthermore being supported from the control rod at its upper end under the by means of a support ring attached to said rod, while the tubular body at its lowermost end is provided with a ground support foot.
Normally, the set of various clubs and balls as well as other accessories required for playing golf are stored in an approximately cylindrical elongated casing of a flexible material, usually called a golf bag. Since the weight of such a bag could amount to 10-15 kg most golf players originally engaged an assistant or so-called `caddy` to carry said bag. With the ever-increasing spreading of the interest for playing golf all over the world said `caddies` since long have been replaced by special collapsible carts on which the bags can be placed for being transported between the various holes along the golf course. As is well known, for climate reasons the outdoor season for playing golf is limited to the summer halfyear in Scandinavia and the northern parts of Europe. Simultaneously with the ever-increasing air charter traffic to primarily the countries around the Mediterranean, the golf sport also has become more moveable and geographically varied. However, most golf players want to play with their own clubs and in order to encourage golf tours by air the international air traffic organization IATA has allowed its members among the air companies to charge an overweight of only 4 kg for a golf bag, presupposed that all golf articles are accommodated within one and the same golf bag and that the total weight thereof does not exceed 15 kg.
However, the last-mentioned stipulation makes it impossible to bring along simultaneously a golf cart weighing 5-10 kg without payment of a particular overweight charge which usually amounts to over 20 SEK per kg or more than 200 SEK for a trip to and from the Mediterranean countries. Therefore, golf players have to hire golf carts at the travel target, which is rather expensive. Therefore, there has since long existed a need for a golf bag design which in itself accommodates travelling wheels in order to eliminate the need of a particular golf cart.
One suggestion to provide such a design has been disclosed e.g. in Applicant's own Swedish patent specification No. 7408665-3. The structure disclosed therein is based on the concept that a golf bag is provided with support legs with trav
