Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. patent application serial number 17 / 984,896, filed on November 10, 2022, entitled “ALL TERRAIN BACKPACK,” the entire contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] The present invention relates to the field of backpacks and more particularly to the field of all-terrain backpacks (eg, wheeled backpacks). Background Art

[0004] A known type of luggage or bag is a rolling or wheeled luggage or bag. However, such bags are often unstable, especially when fully loaded. They are unstable when stationary and tend to tip over unless resting on a more stable surface. They are also unstable when in motion and can be inconvenient, cumbersome, or difficult to control. Furthermore, the wheels are often small in diameter, making them difficult to use on uneven or uneven surfaces (e.g., sidewalks, grass, gravel, snow, etc.) and sometimes challenging to maneuver up and down stairs.

[0005] Known rolling or wheeled luggage, bags, or backpacks often utilize retractable handles to facilitate wheeling. However, these handles are rarely configured for other uses. Notably, these handles themselves are often unstable. For example, they often retract unexpectedly and can be difficult to extend as needed.

[0006] In some activities (e.g., disc golf), it is known to use backpacks to carry contents (e.g., a Frisbee and other equipment). Such backpacks (e.g., a backpack containing a water bottle, a disc golf disc, and equipment) tend to be heavy but perform well on hilly, uneven, and / or rugged terrain.

[0007] Because such backpacks and their contents can be heavy or cumbersome, it is also known to use separate wheeled carts in some activities (e.g., disc golf). A disc golf backpack can be placed in or otherwise coupled to such a cart to allow the backpack and its contents to be wheeled. If the terrain is relatively flatter and smoother, such a backpack (e.g., a backpack containing a water bottle, disc golf disc, and equipment) can be more easily transported on a cart. However, carts do not perform well on certain terrains (e.g., hilly and / or rocky terrain), and the backpack will need to be removed from the cart and carried separately.

[0008] Additionally, known strollers are bulky and often heavy and cumbersome to carry, especially when a backpack or its contents are attached to or connected to the stroller. Known stroller and backpack combinations are not designed or adapted to be carried on the back like a backpack. Furthermore, while convenient in many situations, sitting on known luggage or using it as a seat can be unsafe and / or uncomfortable.

[0009] Additionally, known backpacks, bags, and luggage lack many features that are useful to the user. Summary of the Invention

[0114] refer to Figures 1 to 7 One or more embodiments of a wheeled backpack 10 are provided. The wheeled backpack can be used for disc golf (e.g., to carry a disc, equipment, and supplies) and / or can be used as a bag or luggage for transporting and / or shipping other items. Various applications include hiking, camping, traveling, school, sports, machine work, crafts, lawn and gardening, office, photography, videography, factory or industrial, and military applications.

[0115] In various examples of embodiments, the wheeled backpack 10 includes a backpack 100. In various examples of embodiments, the backpack 100 includes one or more shoulder straps 105 coupled to a rear portion 110 of the backpack 100. The shoulder straps can be adjustable. In various examples of embodiments, the backpack 100 includes a handle 115 secured to a top portion 120 of the backpack 100. In various embodiments, the backpack 100 includes a lower portion 125.

[0116] In various examples of embodiments, the backpack 100 includes a main compartment 130 and may be provided with additional compartments. The compartments are adapted and / or configured to hold or maintain various objects. For example, the main compartment may be adapted to hold a Frisbee golf disc and / or other Frisbee golf equipment. In various embodiments, one or more compartments may include accordion-type holders (e.g., for a Frisbee golf disc). In various examples of embodiments, the backpack includes a compartment for holding a fluid source or reservoir (e.g., a hydration bladder, a water bladder, and / or a water reservoir for a hydration pack). In various examples of embodiments, the backpack includes a compartment (e.g., on the back or drawstring side of the backpack) for holding personal items (e.g., a wallet, a cell phone, a passport, or an ID card, etc.).

[0117] In various examples of embodiments, the backpack includes a compartment for holding a pillow or other head support. In various embodiments, the head support compartment is located on the back or strap side of the backpack to provide additional comfort and / or cushioning to the user's back, spine, and / or waist when wearing the backpack.

[0118] The backpack can be made of nylon, leather, or some other durable fabric or material, and / or a combination of such fabrics or materials. For example, different embodiments of the backpack can be made of the following materials and / or combinations of materials: cotton, canvas, nylon (e.g., ripstop nylon, ballistic nylon, Kodra nylon, etc.), leather, denim, PVC, polyester, polypropylene, Cordura fabric, waterproof materials, etc. Although shown as a soft body or cover (e.g., for storing disc golf equipment or other sporting equipment), in other different embodiments, the backpack can be or include a rigid body cover or bag having various configurations.

[0119] In various embodiments, the wheeled backpack 10 includes a wheel assembly 135 comprising one or more wheels 140 removably coupled to a first axle 145 coupled to the lower portion 125. In various embodiments, the backpack 100 includes sides 150 and 155, with the lower portion 125 comprising the sides 150 / 155 of the backpack 100 or portions of the sides 150 / 155 of the backpack proximate to each wheel 140. In various embodiments, known golf cart wheels may be utilized. Custom wheel designs may also be utilized. In various embodiments, the wheels may be climbing wheels or a set of climbing wheels. In various examples of embodiments, the wheels 140 and / or the first axle 145 are removable.

[0120] In various embodiments, the wheels can be removed or quickly released from the axle, and the wheels and axle can be stowed (e.g., when not in use or when more conveniently stowed in a backpack).

[0121] In various examples of embodiments, the wheels 140 form a track that is relatively wider than or otherwise extends beyond the width of the backpack 100 (e.g., the width adjacent to the track, the width of the lower portion 125, the average width of the lower portion 125 or backpack 100, the maximum width of the lower portion 125 or backpack 100, etc.). In various examples of embodiments, the wheels 140 form a track that is relatively wider than or otherwise extends beyond the width of the lower portion 125 of the backpack 100.

[0122] In various examples of embodiments, the lower portion 125 has a width or a variable width, and the first axle 145 has an axle length that is greater than the width, average width, or maximum width of the lower portion 125. In various embodiments, the wheels 145 have an inner side 160 and an outer side 165. In various embodiments, the outer side 165 of each wheel 145 extends beyond the perimeter of the lower portion 125 of the backpack 100 or is otherwise disposed. In various embodiments, the inner side 160 of each wheel 145 extends beyond the perimeter of the lower portion 125 of the backpack 100 or is otherwise disposed.

[0123] The wheel axles and / or wheel tracks can have a variety of lengths and / or be adjustable to different lengths. For example, in such embodiments, the wheels can be positioned near the periphery or periphery of the lower portion of the backpack, or away from or spaced from the periphery or lower portion of the backpack to create space, increase stability, allow for adjustment relative to the sides of the backpack wearer, etc.

[0124] In various embodiments, a tire 170 (eg, a non-pneumatic or airless tire) is disposed around the circumference of the wheel 140. In various embodiments, the tire 170 is disposed or positioned outside the circumference or width of the backpack.

[0125] This positioning of the wheels and tires provides a number of advantages, including, but not limited to, allowing the wheels (which can be larger than typical luggage wheels, e.g., to facilitate walking on various terrains) to be located near the sides of the wearer of the wheeled backpack 10 or spaced from the wearer's back rather than against or within the back. In various embodiments, the space between the wheels (or the width of the wheelbase) is adjustable to improve the wearer's fit and / or the stability of the wheelbase. Additionally, positioning the wheels outside or beyond the perimeter of the backpack, or at least the lower portion, improves the durability, stability, and / or balance of the wheeled backpack when stationary and / or in motion. In various embodiments, the wheels can be spaced or otherwise arranged so that when the wheeled backpack is carried on the user's back, the wheels can rotate, and the user can spin or otherwise utilize the wheels as a fidget spinner, etc. (e.g., to improve focus and concentration, provide comfort during anxiety and stressful situations, etc.).

[0126] In various other embodiments, the wheels can each have their own axle, which can be coupled to one or more wheels or axle supports. In various embodiments, each such axle is shorter than a single axle configuration, which can be advantageous for storing the axle and wheels when not coupled to a wheel support. Additionally, in various examples of embodiments, the separate wheel and axle combinations can allow for relatively more storage space underneath the backpack.

[0127] In various embodiments, a hubcap 172 axle is removably coupled to the shaft 145 near or on at least one wheel 140. In various embodiments, the hubcap is a disc golf mini-marker that can be used to mark the location of a disc golf ball as required or desired in most disc golf tournaments. The marker can be made of wood, plastic, rubber, metal, or any other material. In various embodiments, one or more markers are coupled to the axle 145 or wheel 140 as hubcaps to keep them accessible and / or prevent them from being lost or misplaced. In various embodiments, the marker defines a hole at or near its center through which the axle 145 can be inserted. The hubcap can also be used as a dining plate, a Frisbee, etc.

[0128] In various examples of embodiments, the pulley assembly 135 further includes a handle assembly 175 coupled to the axle 145. In various embodiments, one or more wheels 140 are removably secured to the axle 145, which is coupled (e.g., rotatably and / or operatively coupled) to the handle assembly 175. In various embodiments, one or more wheels 140 are removably secured to a shaft disposed on an axle tube that is coupled (e.g., operatively coupled) to the handle assembly. Such embodiments can increase stability, strength, and / or durability.

[0129] As desired, the handle assembly 175 can be any length, and its length can be fixed (or otherwise stationary so that it cannot be retracted or otherwise adjusted in length), or it can be retractable or otherwise adjustable to various lengths. The length of the retractable handle assembly 175 can vary (for example, when partially or fully extended). In different examples of embodiments, the handle assembly 175 can be formed from tubing (or multiple sections of tubing). Although the cross-section of the tubing illustrated in the figures is square, the retractable handle tubing can be tubing of circular, rectangular, square, or any other cross-sectional shape. It should be understood that the handle can be fixed (i.e., non-adjustable or non-retractable). In different embodiments, the handle assembly 175 also includes a hidden or concealed storage portion.

[0130] In various embodiments, the handle assembly 175 comprises a series of concentric or nested metal or rigid plastic tubes, including an inner or upper tube 180 that can be telescopically inserted into or withdrawn from an outer or lower tube 185. In various embodiments, the handle assembly 175 comprises two parallel series of concentric tubes connected at the top by a handle or grip 185. The bases of the two series of concentric tubes are coupled to the axle 145, and the outer or lower tube is coupled to the backpack 100 (e.g., the back or strap side of the backpack) so that the handle assembly 175 does not detach from the backpack 100 (e.g., when fully extended). The handle assembly may also include a locking mechanism to maintain the handle assembly in the retracted and extended positions as desired.

[0131] In various embodiments, the retractable handle can be folded into the seat. In various examples of embodiments, the retractable handle can be adjustable so as to be fixed in a U-shape formed by two support sections connected by a crossbar section that can be used as a seat or other support. In various embodiments, pads or other components can be connected to the crossbar section for comfort.

[0132] In various examples of embodiments, the wheeled backpack 10 includes a storage compartment 190 coupled to or disposed on the handle assembly 175. Various items (e.g., pencils, scorecards, snacks, a cell phone, etc.) may be at least temporarily stored or otherwise disposed in the storage compartment 190.

[0133] In various embodiments, the wheeled backpack 10 and / or handle assembly 175 include or are coupled to one or more members 195, such as hooks (e.g., D-shaped hooks), lanyards (e.g., keychain lanyards), loops, and / or one or more magnets, to help retain (e.g., removably retain) one or more items. For example, the backpack and / or handle may include a member 195 for retaining a pet leash 200. In various embodiments, the member 195 may be a headphone strap attachment coupled thereto.

[0134] Now refer to Figure 7 In various embodiments, one or more mounts 205 are coupled (e.g., removably and / or slidably) to the handle assembly 175. For example, one or more mounts 205 for lights, cameras, or other recording devices (including cell phones and smartphones), mobile or cellular devices, reflectors, and the like can be coupled to the handle assembly 175. One or more such mounts 205 can be used to removably retain lights (e.g., spotlights, headlights, strobe lights, red flashing emergency lights, and / or combination lights) on or relative to the handle assembly 175 to help illuminate the area around the backpack and / or make the user more visible to others (e.g., when the user is dragging or carrying the backpack, or when the backpack is resting on the ground). One or more such mounts 205 can also be used to removably retain cameras or recording devices on the handle assembly 175 to help record events as needed (e.g., when the user is dragging or carrying the backpack, or when the backpack is resting on the ground).

[0188] In view of many of the disclosed features, the wheeled backpack embodiments disclosed herein may be useful in military operations, such as those in combat. Combat soldiers must carry all necessary equipment to successfully complete their mission without being burdened by an excessively heavy load. The balance between optimal load and having the necessary equipment depends on the soldier's mission.

[0189] For example, a soldier expecting to fight might carry everything he needs to defeat the enemy (i.e., a "battle load"); therefore, the load is heavy, but not so heavy that it slows or overwhelms the soldier. A soldier expecting to engage in sustained direct firefights with the enemy would carry a battle load, but also carry other supplies to enable the soldier to fight and sustain himself. This combined load is sometimes called a "near march load." A near march load is heavy, but is capped at 100 pounds. A near march load typically includes the following items:

[0190] Close to marching load pound Assault Pack 3.1 t-shirt 0.2 Socks (2 pairs) 0.4 Rain jacket and pants 3.0 poncho 1.0 Raincoat lining 1.5 Weapon Cleaning Kit 1.0 Trenching tool with carrying gear 3.5 2-quart kettles (2 of each) 10.0 Ready-to-eat rations (3 portions each) 4.2 Subtotal 27.9 Plus combat load 68.9 total 96.8 pounds

[0191] Emergency approach march loads are less commonly used for heavy marches. They contain heavy items that cannot be transported by vehicle due to impassable terrain. When used in training, the distances traveled are usually shorter than the standard 12 miles. Similarly, maintenance loads (containing equipment needed for overnight missions) are rarely used to prepare soldiers for longer marches.

[0192] The disclosed wheeled backpack 30 can be equipped with a small parachute so that it can be dropped from an airplane and landed safely on four wheels. The wheeled backpack can also be driven remotely to its destination to supply rations, ammunition, etc.
