Description

BACKGROUND OF INVENTION

[0001] The invention pertains to a golf bag flexible travel cover structure having at least one detachable external bag unit. It pertains particularly to an improved golf bag flexible travel cover structure including a backpack unit removably attached by fastener means to a lower outer front surface of the cover. The detachable bag unit affixed to the exterior of the cover structure is readily removable and has independent functional use such as for a backpack unit. This arrangement for a golf bag flexible cover structure having at least one detachable bag or backpack unit provides for desirable adaptability in its usage, permitting temporary storage of the flexible travel cover after its use by a golfer during travel, and subsequent independent use of the detachable bag unit.

[0002] Because of a definite need by golfers to contain and protect their valuable golf bags containing several expensive clubs during travel by public transportation, thereby requiring handling by baggage handling personnel and equipment, various protective cover configurations for such golf bags have been developed and marketed. Also, it is usually desirable for a traveling golfer to carry along various other items of equipment or clothing, which can be conveniently contained in at least one bag unit removably attached to the golf bag cover. Although some such golf bag covers have been previously developed and are disclosed in the prior art, they have various deficiencies in their structure and/or utility for a traveling golfer.

[0003] Pertinent prior art includes U.S. Pat. No. 4,436,189 to Baum discloses a flexible garment bag having separable side bags attached thereto by zippers. U.S. Pat. No. 4,951,818 to Johnson discloses an elongated horizontal golf bag carrier having flexible side walls and multiple wheels, and has internal impact absorbing panels included in each end. U.S. Pat. No. 5,265,894 to Dunn discloses an upright flexible wheeled cover for a golf bag which has a zippered closure and a permanently attached side pouch for containing golfing equipment. U.S. Pat. No. 5,860,519 to Meyer et al discloses a substantially rigid golf bag which includes a detachable storage pouch, carrying strap and detachable wheels to facilitate movement of the bag during travel. U.S. Pat. No. 5,944,155 to Geary discloses a structured main luggage bag having dual wheels and a small tote bag removably attached onto its outer front side. U.S. Pat. No. 6,109,402 to Godshaw discloses a flexible foldable luggage carrier having attached pouches. U.S. Pat. No. 6,164,425 to Latshaw discloses a rigid container or cover unit for enclosing a golf bag, and includes dual wheels and at least one smaller piece of luggage removably attached to the main container by mating snap fasteners. Also, U.S. Pat. No. 6,216,926 to Pratt discloses a backpack unit having a detachable portion. However, further improvements in flexible travel covers for golf bags are desired by many golfers to provide increased convenience and flexibility in their use during and after travel by public transportation such as in airports.

SUMMARY OF INVENTION

[0004] It is an object of this invention to provide an improved flexible cover structure for golf bags which provides added convenience and safety for retaining a golf bag therein during handling and travel by public transportation.

[0005] Another object of the invention is to provide a cover structure for golf bags which alone is flexible and light weight, but when enclosing a golf bag has sufficient rigidity to permit convenient and reliable handling during travel.

[0006] A further object is to provide such a flexible cover structure including at least one smaller detachable bag unit which is removably attached to the cover lower front side and is adapted for independent use such as preferably a backpack unit.

[0007] This invention provides an improved golf bag generally flexible travel cover structure adapted for enclosing and protecting a golf bag containing several clubs, such as during baggage handling and travel on public transportation and particularly on airplanes and trains. The cover structure is shaped for reliably enclosing a golf bag for convenient and safe handling by personnel during its transport, and includes at least one smaller bag such as a backpack unit removably attached by suitable fastening means such as by snaps or zipper means to the cover structure outer surface at its front lower portion.

[0008] The golf bag cover structure has an elongated and generally rectangular cross-sectional shape, and is made of a durable flexible waterproof fabric material such as canvas, nylon or polyester stitched together with beading provided along the seams. The cover structure includes a rigid base member located at the cover lower end, and which has a rear extended portion extending upwardly along its rear side. The base member is equipped with dual rollers and dual pedestals attached to the rigid base member lower surface,, and also includes multiple elongated rigid spaced-apart bumper elements firmly attached to the rigid base member rear extended portion outer wall, and extending longitudinally for facilitating handling of the bag cover structure over uneven surfaces and particularly on stairs. The cover structure upper portion includes dual internal padding elements located on its front and rear sides and adapted for cushioning and protecting the golf club heads during handling. The cover structure also includes a towing handle provided at the cover structure upper end, and also has a carrying handle provided along one side of the cover at an intermediate location. It is an important feature of this invention to provide a cover structure for golf bags which alone is inherently relatively flexible and light weight, but whenever a golf bag is enclosed inside the cover structure becomes sufficiently rigid to provide for convenient handling during transport.

[0009] The cover structure of this invention includes a detachable bag unit such as preferably a backpack unit removably attached by suitable means such as by snaps or zipper onto the cover structure outer surface at its front lower portion. . The detachable backpack unit is preferably removable by a continuous zipper, which is sewn to a lower front portion of the golf bag travel cover and also to the rear periphery of the backpack unit. The detachable backpack unit includes a rearward main inner compartment which is closable by a zipper fastener extending along its opposite sides and upper end, and also includes a front smaller forward secondary compartment which is closable by a zipper extending along its sides and across its upper end. The backpack unit is provided with dual shoulder straps attached along the unit rearward side, and adapted for being placed around the shoulders of a hiker.. The golf bag cover structure and the detachable backpack unit of this invention advantageously provides complementary equipment and function for traveling golfers and hikers.
