Golf bag and golf trolley, as well as golf bag-golf trolley unit

Description

[0001] The invention relates to a golf bag according to the preamble of claim 1, a golf trolley according to the preamble of claim 7, and a golf bag-golf trolley unit comprising a golf bag and a golf trolley according to claim 15. State of the art

[0002] Without a motorized golf caddy, golfers typically cover several kilometers on foot during a round of golf. They carry up to 14 different golf clubs, the maximum permitted for one round, in a specially designed golf bag. To avoid having to carry the bag and clubs constantly, the player usually transports the bag on a multi-wheeled cart. State-of-the-art golf carts are two- and three-wheeled models, often called trolleys, which are conventionally pulled behind the player or, more recently, increasingly pushed in front as three-wheeled push trolleys. Examples of golf carts are disclosed in documents US 2013 / 0234418A1, US 2012 / 0261908, and US 2012 / 0112436A1. These golf carts are characterized by the fact that the golf bag and chassis are separate units that are only connected for the purpose of playing the game.The disadvantage of these golf carts is that they are often not very stable, usually take up a lot of space during transport, and require a lot of time to set up and fold away.

[0003] A newer generation of golf carts has the wheels and handle attached directly to the golf bag; that is, the wheels and handle are integral to the golf bag and thus comparable to a rolling suitcase with two or four fixed wheels. "Integral" therefore means that the golf bag and chassis form a single unit, hereinafter also referred to as a golf bag cart, and are inseparable.

[0004] European patent EP 0 055 873 B1 discloses a two-wheeled golf cart with a drawbar for pulling the cart and a container divided into several compartments. The wheel frame is partially frictionally connected to the container and arranged such that, in the active position of the wheel frame, the weight of the container is evenly distributed and the free end of the drawbar is relieved of stress. A first compartment of the described golf cart serves to hold the wheel frame and its actuation mechanism in their inactive position, a second compartment holds the golf clubs, and a third compartment is provided for holding various accessories.

[0005] To swivel the wheeled frame from its inactive storage position to the active transport position, a locking mechanism is released. This causes the two-legged wheeled frame to rotate around a pivot pin under spring pressure and swing out of the container. When the drawbar is raised, the articulated arms, and thus the legs of the wheeled frame, are spread apart. A disadvantage of this golf trolley is that, in its unused position, the wheeled frame is located in the center of the container, thus wasting valuable space for arranging golf clubs inside.

[0006] EP 2 581 291 A2 discloses a four-wheeled, foldable golf cart that can be folded and unfolded from a non-use position to a use position. The golf cart comprises a golf bag trolley unit and a bag that can be attached to the golf bag trolley unit. The golf bag trolley unit has two front wheels at one end, which are spaced apart and rotatable about a fixed first axis of rotation. Two rear wheels, which are rotatable about a second axis of rotation, are located at a distance from these. These rear wheels can be pivoted from a folded position to an unfolded or spread position. In the folded position, the wheels hold the golf cart unit in a horizontal position, with the second axis of rotation located at the first end of the golf bag trolley unit.

[0007] The golf bag trolley unit has a rear wheel assembly that is attached to the body of the trolley via a mounting bracket. The rear wheels of the rear wheel assembly are connected to a sliding block via a boom tube and a rod, allowing the sliding block to move between two extreme positions. Additionally, a pull rod connects one point of the boom tube to the sliding block. When the sliding block is moved from one extreme position, where the rear wheels are close together, to the other extreme position, the pull rod pulls the rear wheels apart. This movement is further assisted by gas springs.

[0008] The American patent application published under No. US 2013 / 0234420 A1 discloses a three-wheeled, combined golf bag cart that can be easily folded and unfolded and has the shape of an offset parallelogram. The golf bag cart consists of several subassemblies, namely an outer frame, a parallelepiped-shaped container for the clubs, a front and a rear wheel assembly, and a handle. The outer frame includes a base plate held by two lateral beams, forming an angle of approximately 120 degrees with them. A front frame support, which supports the golf club container, is also attached to the lateral beams. The golf club container consists of individual tubular compartments that extend longitudinally along the container.The front wheel unit is arranged on the base plate via fork arms and can be pivoted via a pivoting mechanism from a position in which the fork arms represent an extension of the base plate to a position in which the fork arms with the wheel are arranged below the golf club case.

[0009] The rear wheel assembly consists of two rear wheels, each rotatably mounted on an axle. The axles are each connected to the side beams of the frame via a lever and can pivot around a pivot axis. A turntable with two notches is mounted on this pivot axis, into which a stop post can engage in the two extreme rotation positions.

[0010] In an alternative embodiment, the golf bag trolley consists of a golf club container, a transport assembly that facilitates transport on the golf course, and an extension assembly that works together with the other two assemblies to fold and unfold the golf bag trolley.

[0011] The golf club case consists of a base plate, a rigid collar, and a thermoformed back plate that connects the base plate and collar. Parts of the inner frame and the base plate are shaped towards the front of the golf club case to define a wheel cavity in the center.

[0012] The transport assembly comprises a front wheel held by two arms. The arms are attached to the base plate at a front pivot point and can be pivoted about a pivot axis from a working position, in which the front wheel is positioned in front of the base plate, to a non-working position, in which the front wheel is received in the wheel cavity.

[0013] The rear wheels are each attached to the back plate of the golf club case via two parallelogram levers. One of the parallelogram levers is connected to the pivoting handle via a push rod. When the handle is pivoted from the unused to the used position, the rear wheels also extend into the used position. A ramp formed at the pivot point ensures that the wheels also move apart during extension.

[0014] A disadvantage of this golf bag trolley is that several handles are required to fold and unfold it. First, the front wheel must be moved into the working position, followed by the rear wheels. Also, the golf bag and the transport unit are a single, integrated unit and not designed to be separated. Consequently, this golf bag trolley is relatively heavy.

[0015] American patent US 8,764,030 discloses a sports bag arrangement with an integrated transport system with wheels. The special feature of the sports bag arrangement of US 8,764,030 is that the transport system can be stowed within the geometry of the sports bag and deployed with a single mechanical movement. The transport system is unfolded by pulling a handle, which causes a front wheel to extend in the opposite direction and two rear wheels to spread apart. For this purpose, first racks are formed on the U-shaped handle, each connected via a gear to a second rack on which the front wheel is mounted. When the first racks are moved in one direction, the second racks move with the front wheel in the opposite direction. The movement of the first and second racks occurs relative to a stationary clamp of the sports bag arrangement.

[0016] The rear wheels are mounted on pivoting legs, each connected to the first set of racks via a pivoting arm. When the handle of the sports bag assembly is pulled upwards, the legs with the rear wheels spread apart. To ensure the rear wheels fit into a recess in the sports bag when at rest, they also pivot.

[0017] The described sports bag with its integrated transport system has the advantage of being compact and easy to store, and it can be set up or folded with a single movement. A disadvantage is the complex design of the transport system, which features many articulated joints and negatively impacts its stability. Another drawback is that the sports bag must be carried in its folded position because all the wheels are retracted. The space previously occupied by the wheels in the folded position is then no longer available for storing golf clubs, thus increasing the overall length of the sports bag.

[0018] EP 2 819 908 relates to a combination of a golf trolley and a golf bag designed to carry a set of golf clubs. The combination can be transformed from a transport or storage state into an operational state, allowing it to be wheeled around a golf course. The golf trolley has a chassis with a base and an elongated base plate extending downwards to a central wheel. The base plate has a 90-degree upward-curving extension at its lower end, which serves as a stop for a golf bag. A battery unit can be mounted on this extension if the golf trolley is motorized. The central wheel extends beyond the lower part of the base plate, so that when upright, the golf trolley rests on both the central wheel and the two coaxial rear wheels. Furthermore, the central wheel is enclosed in a small wheel well, preventing it from coming into contact with the golf bag.

[0019] The middle wheel of the described golf trolley has a very small diameter compared to the other two wheels. This has the disadvantage that small obstacles, such as stones, make it difficult to move the golf trolley.

[0020] The bag is designed as an integral part of this product, but alternatively, it can be detached from the trolley and attached to the chassis using suitable fasteners. The EP 2 819 908 golf trolley is an all-in-one golf cart that, when folded, is comparable in size to a conventional golf bag and fits securely on the back seat of a car.

[0021] US Patent 10,471,314 B1 discloses a multi-wheeled golf cart that combines the functionality of a conventional cart and a golf bag into a single piece of equipment. The cart is designed to fold into two positions: a folded position for storage and transport, and an extended position for walking. Using axles and brackets, the two rear wheels are mounted on trailing arms, which are then attached to the lower chassis mounts. The center wheel is mounted on the center fork, which is attached to the lower chassis. The lower chassis is attached to the middle chassis, and the latter is in turn attached to the upper chassis. The pushrod assembly is attached to the upper chassis using two mounting collar brackets.

[0022] FR 2 749 768 discloses a golf set consisting of a storage element supported by a trolley and a towing unit detachable from the storage element. The towing unit is located in the base region of the storage element and docked to a front axle of the trolley, with the towing unit occupying the entire base area of ​​the storage element.

[0023] What all golf bag trolleys currently available on the market have in common is that they are often complicated to assemble and unfold, requiring several steps. Women, in particular, often struggle to get the trolley ready for use in a reasonable amount of time. Furthermore, their weight is usually so considerable that women find them difficult to handle.

[0024] The present invention (according to the attached claims) relates to a golf bag and a separate golf trolley (transport assembly) which can easily be combined to form a golf bag-golf trolley unit and can be transported as such. Object of the invention

[0025] The object of the present invention is therefore to provide a golf bag-golf trolley unit that possesses both the advantageous properties of a sports bag with an integrated transport system and the advantageous size characteristics of a golf bag. This means that the golf bag and golf trolley should be easily connectable with as few steps as possible and, when combined, be very compact and only slightly heavier than a golf bag alone. The aim is that the golf bag and golf trolley, although designed as separate units and easily disassembled, can be transported as a golf bag-golf trolley unit. The golf bag-golf trolley unit should not be larger than a conventional golf bag. A further objective is that the golf trolley can be set up or folded down with a single movement.The golf bag-trolley unit, consisting of a separate golf bag and trolley, should not need to be carried when folded; i.e., it should be wheeled. When not in use, the golf bag-trolley unit should be as compact and space-saving as possible. Another goal is to further develop the golf trolley so that the chassis is as stable as possible. The combined golf bag-trolley unit should also be as lightweight as possible. A further goal is for the golf bag-trolley unit to be as comfortable as possible for a golfer to maneuver. It would also be advantageous if the golf bag's appearance could be changed. Description

[0026] The invention relates to a golf bag for detachable attachment to a golf trolley, with a storage space for a plurality of golf clubs, comprising a bottom part, a top part, a support frame connecting the bottom part to the top part, and a covering arranged on the support frame, preferably made of a textile or solid material, which surrounds the storage space for the golf clubs, wherein the golf bag is designed to be detachably attached at least two points to a three-wheeled chassis.

[0027] According to the invention, the golf bag is characterized by the fact that a wheel housing for the front wheel of a three-wheeled golf trolley is provided in the base of the golf bag, and the base is designed to rest against the front axle of the three-wheeled golf trolley. The provision of a wheel housing integrated into the golf bag has the advantage that a suitably designed chassis of a golf trolley can be accommodated largely within the periphery of the golf bag. Furthermore, the golf bag can have essentially the same axial length as known golf bags, the length of which is essentially determined by the length of the golf clubs. In the context of the present invention, "can be accommodated within the periphery of the golf bag" means that the chassis of the golf trolley is substantially concealed by the outer casing of the golf bag when viewed from the front or side.

[0028] The wheel arch is advantageously designed as a slot-shaped recess. This recess is slightly wider and taller than the front wheel it accommodates and extends from the rear to approximately the middle of the floor section or beyond. This has the advantage of providing space to the sides and in front of the wheel arch for the golf club handles.

[0029] Preferably, the wheel arch has two opposing side walls with rearward-projecting ribs molded into them at approximately half their height. These ribs have aligned recesses for accommodating the front axle of a golf trolley. This allows the wheel's axis of rotation to run behind the wheel arch, increasing the footprint of the combined golf bag-golf trolley unit and ensuring good stability when the chassis is folded. In this configuration, the wheel's tread can be approximately flush with the base of the trolley.

[0030] It is advantageous to provide feet on the underside of the base to form a stable support surface.

[0031] Preferably, the axial distance between the base surface of the floor part and the recesses for the wheel axle is dimensioned such that the running surface of a front wheel received in the wheel housing is essentially aligned with the base surface.

[0032] A key advantage is that the base has a surrounding rim. This allows the rackets to be positioned around the wheel arch. Furthermore, the fabric cover can be secured at the rim.

[0033] According to an advantageous embodiment, a head section is provided opposite the base section, in which a recess is provided for receiving the support profile of a golf trolley. This has the advantage that the golf trolley and golf bag can form a very compact unit that is hardly larger than a conventional golf bag.

[0034] The head section is advantageously connected to the base section by means of several rods. The base section, head section and the rods thus form a frame for the golf bag, which can be covered with a sleeve.

[0035] Advantageously, the rods arranged on the back of the golf bag define a recess for receiving part of a golf trolley's chassis. This allows a part of the golf trolley's chassis, e.g., an elongated support profile, to be held in the recess.

[0036] Advantageously, a clamp connecting two or more rods is provided at approximately half the height, defining an approximately semicircular indentation when viewed from above. The support profile of the golf trolley, formed from a tube, can extend within this indentation. This means that the support profile can run in an elongated, rearward-opening channel of the golf bag.

[0037] An alternative embodiment provides that an outwardly (rearwardly) open channel for receiving the elongated support profile (15) of a golf trolley is provided adjacent to the wheel arch for the front wheel. The channel can, for example, be a plastic profile that connects the base and head sections. The head section can also have a semicircular recess for receiving the tubular support profile.

[0038] Advantageously, the channel for the support profile runs primarily along the periphery of the golf bag's outer casing. This means that the support profile of the golf trolley is practically invisible from the side. As a result, the golf bag and trolley unit is very compact.

[0039] Preferably, the golf bag has a recess on each side for receiving the rear wheels of the golf trolley, so that the rear wheels of a three-wheeled golf trolley are also located within the periphery of the cover when the golf trolley is folded (viewed from the front or rear).

[0040] Advantageously, the cover of the golf bag has side panels that extend backwards. These side panels can be made of a slightly sturdier material so that the golf bag can rest on them during transport in a vehicle. In any case, it is advisable that the support frame and the parallelogram levers do not protrude beyond the side panels when the golf trolley is folded (when viewed from the side).

[0041] Conveniently, the headboard has compartments for holding various golf clubs, so that the golf clubs can be arranged clearly.

[0042] It's conceivable that a wheel is already permanently mounted in the wheel well of the golf bag. Accordingly, a golf trolley would only need to have two adjustable rear wheels.

[0043] The present invention also relates to a three-wheeled golf trolley for holding a golf bag, comprising a chassis a front wheel and two rear wheels, wherein the rear wheels are each articulated to the chassis by means of two parallelogram levers and can be moved from a narrow transport position to a spread driving position and vice versa, a steering rod movably arranged on the chassis, which is connected to the parallelogram levers by means of two struts, wherein the rear wheels can be moved from the transport position to the driving position and vice versa by means of the steering rod.

[0044] The golf trolley according to the invention is further characterized in that the front wheel has an axle with axial extensions on both sides, which form a support for a golf bag on opposite sides of the front wheel. Such axial extensions of the wheel axle are not known before. The provision of such axle extensions has the advantage that the golf bag can be hung on them and the axle extensions can form part of a positive-locking connection.

[0045] Advantageously, a fork with U-shaped recesses is provided or formed on the support profile to accommodate the front wheel axle. The fork is preferably fixed to the support profile and not rotatable.

[0046] Ideally, the axle of the front wheel should extend beyond the fork on both sides by a certain distance, for example 0.5 to 3 cm, so that a golf bag can be supported or hung on it.

[0047] Advantageously, the steering rod is attached to the support profile via a connecting piece, such that the pivot axis is located a certain distance behind the support profile. This has the advantage that, when folded, the support profile and steering rod are essentially parallel to each other, and the pivot axis of the front wheel runs at a distance from the support profile. This makes it possible to lift the golf bag placed on the golf trolley off the ground and move it by tilting it backward. The rear wheels remain in contact with the ground during this process.

[0048] Advantageously, connecting elements are provided at a distance from the second end of the support profile to create a form-fit and / or force-fit connection with a golf bag. A two-point connection allows a golf bag to be reliably attached to the support profile of the golf trolley. A technically simple solution involves attaching the golf bag to the support profile using a strap or elastic band. The strap or elastic band can be part of the golf trolley or the golf bag itself.

[0049] Preferably, the parallelogram levers are pivotably mounted on a bracket such that the pivot axis runs a short distance to the side and behind the support profile. This has the advantage that, in the folded state, the axis of rotation of the rear wheels runs behind the support profile.

[0050] The wheel arch is advantageously designed as a receiving slot. This slot is large enough to accommodate approximately 40 to 50% of the cross-sectional area of ​​the golf trolley's front wheel.

[0051] The base is advantageously designed to rest against an extended axle of the front wheel of a three-wheeled golf trolley.

[0052] Advantageously, the wheel arch has two opposing side walls with molded-in ribs at approximately half their height. These ribs feature aligned recesses for accommodating a front wheel axle. This allows the golf bag's base to be hooked onto the front wheel axle, creating a positive connection. This design ensures that the front wheel's tread aligns with the base's contact surface, allowing the golf bag / trolley unit to rest securely on the ground with both the base and the front wheel. As a result, even when folded, the golf bag / trolley unit remains stable and won't easily tip over.

[0053] Advantageously, the receiving area is designed to accommodate between 30 and 70%, preferably between 40 and 60%, and most preferably between 40 and 49% of the cross-sectional area of ​​the front wheel. This means that the front wheel protrudes largely from the wheel arch.

[0054] Advantageously, the base section has a largely flat floor, and the wheel arch for the front wheel extends approximately at right angles to the floor. This leaves enough space for storing several golf clubs.

[0055] According to a preferred embodiment, an outwardly open channel for receiving the support profile of a golf trolley is provided adjacent to the wheel arch for the front wheel. This has the advantage that the channel for the support profile can run essentially along the periphery of the casing, which ensures the compactness of the combined golf bag-golf trolley unit.

[0056] Advantageously, feet are provided on the underside of the base section. This ensures that the combined golf bag / golf trolley unit stands securely when folded. The base section is preferably tub-shaped with low, surrounding side walls. A head section is advantageously provided opposite the base section, which is connected to it by several rods. This results in an ultra-lightweight construction, especially if the rods are made of carbon fiber reinforced plastic.

[0057] Preferably, the headboard has compartments for holding various golf clubs, so that they can be arranged clearly and easily removed.

[0058] According to another aspect of the invention, the front wheel of the golf trolley is fixedly mounted in the wheel well of the golf bag.

[0059] The present invention also relates to a three-wheeled golf trolley for holding a golf bag, with a wheel housing provided in the bottom part of the golf bag. a longitudinal, in particular tubular, support profile, a front wheel arranged at a first end of the support profile, a steering rod articulated at a first end to the second end of the support profile, and pivotable in a plane from a first position in which the steering rod rests against the support profile to a second position in which the steering rod forms an obtuse angle with the support profile, locking means to fix a position of the steering rod once assumed relative to the support profile, two rear wheels articulated by means of two parallelogram levers to opposite sides of the support profile, two struts articulated at one end to at least one of the parallelogram levers and at the other end to the steering rod, such that the rear wheels can be moved from a narrow transport position to a splayed driving position and vice versa when the steering rod is pivoted.This golf trolley is designed to be combined with a golf bag according to any one of claims 1 to 18 and has the special feature that the front wheel has an axle whose axial extensions on opposite sides of the front wheel form a support for a golf bag. This allows a suitably designed golf bag to be attached to the golf trolley and form a compact unit with it. The golf trolley according to the invention is generally pushed, so in the description the "middle wheel" is referred to as the "front wheel" and the other two wheels as the "rear wheels". It is clear to the reader that the golf trolley can, of course, also be pulled.

[0060] Advantageously, the support profile is provided or designed with a fork featuring U-shaped recesses that serve to accommodate the front wheel axle.

[0061] Advantageously, the axle of the front wheel extends beyond the fork by a certain distance on both sides.

[0062] According to an advantageous embodiment, the steering rod is arranged on the support profile via a connecting piece such that the pivot axis is located a certain distance behind the support profile. This has the advantage that the support profile and steering rod can run essentially parallel to each other when the golf trolley is folded.

[0063] Advantageously, connecting means are provided at a distance from the second end of the support profile to create a form-fit and / or force-fit connection with a golf bag, so that the golf bag and golf trolley can form a unit that can be transported together, thus realizing the advantages of an integrated golf bag trolley.

[0064] Advantageously, the parallelogram levers are pivotably mounted on a bracket such that the pivot axis runs a short distance to the side and behind the support profile. This has the advantage that the rear wheels are positioned a short distance from the support profile when folded.

[0065] Advantageously, the rear wheel assembly can be pivoted around a rotation axis provided on the chassis, in particular the support profile. This allows the rear wheel assembly to be quickly brought into the operating position.

[0066] Advantageously, the chassis includes a preferably elongated support profile. Providing a central support profile extending longitudinally along the golf trolley has the advantage of giving the trolley great stability. However, it is also conceivable to use a frame construction instead of a rod-shaped support profile, while the rest of the construction could remain the same.

[0067] In another embodiment, the device for guiding the golf trolley is arranged on a steering rod that is pivotally attached to the support profile and additionally articulated to the rear wheel assembly. This embodiment has the advantage that by pivoting the steering rod, it can be moved from a non-use position (folded position), in which the steering rod rests almost or completely against the rear of the golf trolley or the rear wheel assembly, to a use position, in which the steering rod forms an angle of up to 20 degrees to the longitudinal axis of the support profile, into a ready-to-use, unfolded position. When setting up the golf trolley, the steering rod is preferably pivoted between approximately 130 and 180 degrees.

[0068] Preferably, the rear wheels are directly or indirectly attached to the support profile or frame by means of a wheel support. This ensures high stability for the entire golf trolley.

[0069] Advantageously, the device for guiding the golf trolley includes a steering rod, which is articulated to the support profile. This design ensures high stability of the golf trolley while keeping the weight low.

[0070] According to a particularly advantageous embodiment, the steering rod and wheel supports are mechanically coupled to each other by means of a strut. This provides good support for the steering mechanism because loads can be transferred directly to the wheel supports via the struts.

[0071] Advantageously, the device for guiding the golf trolley includes a handle that is rotatably mounted on the handlebar and therefore height-adjustable. This allows the handle to be adjusted to different heights to suit the golfer's height.

[0072] Advantageously, the front wheel is mounted so that it can rotate freely at the front end of the support profile. This also enhances the stability of the golf trolley when the front wheel is positioned directly against the support profile. The support profile can incorporate a wheel fork similar to a bicycle fork to mount the front wheel. The pivot axis of the front wheel is advantageously located below and at a distance from the longitudinal centerline of the support profile.

[0073] Preferably, the rear wheels are positioned close to the sides of the base of the container when folded. For this purpose, the base may have lateral recesses or niches in which the rear wheels are partially or preferably completely accommodated when not in use, so that they do not protrude laterally beyond the golf bag, i.e., the wheelbase is no wider than the golf bag. This is a space-saving design and ensures a compact golf bag-golf trolley unit.

[0074] Advantageously, when the golf bag / golf trolley unit is not in use, the rear wheels are at least partially recessed within the outer contour of the base and / or the outer casing, as seen from above. The more the rear wheels are recessed within the outer contour of the casing, the more compact the entire golf bag / golf trolley unit is.

[0075] The cover advantageously connects the base and head sections and has a front and a back, as well as two side surfaces connecting the front and back. The cover can be replaceable and made of different materials such as plastic, fabric, shell, etc.

[0076] The base section conveniently features a bevel to improve the ground clearance of the golf trolley when in use. This bevel is located between the back and the bottom of the base section. The degree of beveling can vary depending on the position of the front wheel within the base section.

[0077] If, in the non-use position, the pivot points of the rear wheels and the pivot point of the front wheel are spaced apart, the golf trolley can stand upright without the base needing to rest on the surface. However, it is equally conceivable that, in the upright, folded position, the trolley's body rests on the ground. Thus, in the upright, folded position, the golf trolley can stand on its front wheel and / or rear wheels and be supported by its base, allowing the golf bag / trolley unit to assume a stable position.

[0078] The rear wheel assembly is advantageously mounted to the chassis in such a way that when it pivots from the non-use position to the use or driving position, the wheel supports spread apart. This has the significant advantage of improving the stability of the golf bag / golf trolley unit and virtually eliminating lateral tipping, even on hilly terrain. Conveniently, the rear wheels can be spread to approximately twice their width relative to their basic (non-use) position.

[0079] Advantageously, in the driving position, the rear wheels and the front wheel support the chassis and the container in an inclined position, in which the wheel supports are preferably arranged at approximately a right angle to the carrier.

[0080] Advantageously, the head section features multiple openings for inserting the golf club shafts, allowing the desired number of clubs to be carried. To facilitate easy removal of the clubs and create a visually tidy appearance, the clubheads are preferably positioned within the head section. Multiple openings in the head section can be provided for this purpose. To guide the clubs within the container, individual tubes extending to the base section can be attached to the underside of the head section.

[0081] Preferably, a handle is provided that is hinged to the rear (distal) end of the handlebar and can be locked in various positions. This has the advantage that the handle can be adjusted to the size of the golf trolley user.

[0082] In another embodiment, a handle is movably mounted longitudinally on the handlebar and mechanically connected to a bolt. This allows the handlebar to be unlocked by pulling the handle back far enough to disengage the bolt. Advantageously, the bolt is pre-tensioned into a locking position by means of a spring element. This has the advantage that the bolt can automatically engage when the handlebar is pivoted and the handle is released.

[0083] A snap mechanism is advantageously provided to lock the steering rod in the non-use position. This allows the operating rod to be detachably fixed in both the use and non-use positions.

[0085] The in the Figures 1 to 10The first embodiment of a golf trolley 11 shown comprises a chassis 13 with an elongated support profile 15, a non-adjustable front wheel 19 fixedly arranged at the front end 17 of the support profile 15, and a righting unit 20 with a steering rod 23 articulated at the rear end 21 of the support profile and a rear wheel unit 25 arranged between the front and rear ends 17, 21, with two rear wheels 27 and two struts 28. A golf bag 53 is detachably attached to the golf trolley 11. The golf bag 53 has a base 29 and, opposite it, a head 30, which are connected to each other via a frame that will be described in more detail below. These components and their interaction are explained in more detail below.

[0086] The base section 29, when the golf bag is fully equipped, holds the grips of golf clubs 31, also known as "irons" in golf jargon. The base section 29 is part of the golf bag and comprises a bottom 33, a front 35, a back 37, and two side surfaces 39 that connect the front and back surfaces 35, 37. Fig. 1 The front and rear surfaces 35, 37, as well as the two side surfaces 39, extend essentially at right angles to the base 33 and form a circumferential, upwardly projecting collar that has a height of between 5 and 10 cm relative to the base 33. In the middle of the base section 29, a slot-shaped wheel housing 40, open to the rear and bottom, is provided, in which slightly less than half of the cross-sectional area of ​​the front wheel 19 fits ( Figures 1 and 2The wheel arch 40 and the diameter of the front wheel 19 are aligned such that the tread of the front wheel is approximately flush with the underside of the floor section 29. A chamfer 41 is formed between the rear 37 and the base 33 of the floor section 29 to ensure sufficient ground clearance between the floor section 29 and the support surface 43 or roadway when the golf trolley is in driving position. A chamfer 41 is necessary when the wheel axle is located a short distance from the rear 37 within the floor section 29.

[0087] The head section 30 of the golf bag 53 is detachably arranged on the support profile 15 and essentially consists of an approximately circular, semicircular or U-shaped molded part 45 in which individual, preferably circular or rectangular openings 47 are provided for inserting the golf club shafts 49 ( Figs. 7 and 8Instead of a molded part 45, a circular, semicircular, or U-shaped frame, preferably made of a dimensionally stable plastic, can also be provided. A [feature] is provided on the bottom and top parts 29, 30. Figures 5 and 6 A cover, shown with dashed lines, is arranged which, together with the bottom and top sections 29, 30, defines a container for the golf clubs 31. The cover, advantageously made of textile material, is preferably detachably connected to the bottom and top sections 29, 30 by means of rivets, snap fasteners, a Velcro closure, clamping elements or the like. This has the advantage that the cover can be replaced in case of damage, or if the appearance of the golf bag is to be changed for fashion reasons.

[0088] The rod-shaped support profile 15 of the golf trolley has at its front end 17 a downwardly angled extension 55 in the operating position, to which the front wheel 19 is articulated and rotatable about a pivot axis 57 ( Fig. 10 ). Due to the downward angling of the support profile 15, the axis of rotation 57 of the front wheel 19 is located at a distance from a longitudinal center line 58 passing through the support profile ( Fig. 10 This allows the recess 41 in the base section 29 to be slightly smaller, because the front wheel dips less deeply into the container, thus providing more space overall for storing the golf clubs.

[0089] The rear wheel assembly 13 of the golf trolley comprises two separate wheel suspensions on which the two rear wheels 27 are freely rotatable. Each wheel suspension includes a wheel support 59, which is connected to the support profile 15 by means of a joint 61 and is pivotable about a pivot axis 63. The joint 61 for the linkage of the wheel supports 59 is located, viewed longitudinally along the golf trolley, a certain distance, preferably between 5 and 20 cm and particularly preferably between 8 cm and 14 cm, above the center of the support profile 15. At the other end of the wheel support 59, the rear wheel 27 is freely rotatable about a pivot axis 65. The wheel support 59 comprises two separate and spaced-apart parallelogram levers 60a, 60b, which are pivotable about the pivot axes 63.Because the two parallelogram levers 60a,60b are hinged at different points, the wheels are swung away from the support profile parallel to each other when unfolding, so that they are also parallel to each other in the operating position.

[0090] The steering rod 23 for unfolding or folding the golf trolley is articulated to the first, rear end of the support profile 15 and can be pivoted about a pivot axis 69. The struts 28 provide a pivotable connection between the steering rod 23 and the wheel supports 59 via the pivot points 73 and 75. When the steering rod 23 is pivoted, the wheel supports 59 are also pivoted by positive guidance. In one extreme position of the erecting unit, defined by the non-use position, the wheel supports 59, the steering rod 23, and the struts 28 extend essentially parallel or at a small angle (up to a maximum of approximately 5 degrees) to the support profile 15. In the other extreme position, defined by the use position, the wheel supports 59 describe approximately a right angle to the support profile 15, and the steering rod 23 extends at an angle α of approximately 15 degrees to the support profile 15. Fig. 14In this position, the support profile 15 and the golf bag 53 arranged on the support profile 15 assume an angle of approximately 40 to 50 degrees to the road surface 43.

[0091] The Figures 7 and 8 The diagram shows the arrangement of the golf clubs 31 in the golf bag 53 in more detail. For golf clubs 31 with a standard shaft length, a total of nine 47" holes are provided in the molded section 45, grouped in a "U" shape. Four additional 47" holes are located below the aforementioned nine 47" holes, closer to the outer edge of the molded section 45. These 47" holes are reserved for extra-long golf clubs.

[0092] Holes 47' and 47" can be connected to the underside of the molded part 45 by tubes made of plastic or a textile material, in which the golf club shafts 49 are guided or received. These tubes are shown in the diagram for illustrative and clarity reasons. Fig. 8 However, it is not shown. As can be seen from the Figure 1 ,5 and 8 As can be seen, the shafts of the three upper golf clubs 31' extend essentially parallel to the longitudinal center line 58 ( Fig. 10) of the support profile 15, the other six golf clubs 31' of the U-shaped arrangement are inclined towards the center, so that they come to lie in the container in the space between the wheel arch 40 provided for the front wheel 19 and the rear wheels 27. The shafts 49 of the extra-long 31" golf clubs, on the other hand, utilize the remaining space between the (not shown) outer casing and the six laterally arranged 31" golf clubs. Within the container 53, they extend diagonally from the top rear to the bottom front when the golf bag-golf trolley unit is upright. This diagonal arrangement of the golf clubs allows for up to approximately an additional 5 cm of shaft length to be accommodated within the container. The terms "top" and "rear" refer to the operating position and direction of travel of the golf bag-golf trolley unit and are not to be understood as limiting characteristics. "Rear" of the golf bag is where the front wheel of the golf trolley protrudes from the base.

[0093] In the Figures 11 to 14The locking mechanism for the steering rod 23 is shown. This locking mechanism ensures that the steering rod 23 is securely fixed in the unfolded position of the golf trolley at an angle of approximately 10 to 30 degrees to the support profile 15. The special feature of the golf trolley according to the invention is that it can be moved from the folded (non-use position) to the unfolded (use position) position with a single movement. This is in contrast to the integrated golf bag trolleys mentioned earlier, which require several movements to unfold. To make setting up the golf trolley as easy as possible, a pivot joint 79 is provided at the rear end 21 of the support profile 15. The pivot joint 79 has a pivot pin 81 on the support profile 15. The steering rod 23 is mounted on the pin 81, and for this purpose it has a slightly thicker connecting piece 82 with a bore 83.The steering rod 23 is tubular in shape with a channel 85. A cable 87 extends into this channel 85, which provides a mechanical connection between a handle 89 slidably mounted on the steering rod 23 and a movable locking bolt 91, which is received in a blind hole 93 on the end face of the steering rod 23.

[0094] The locking bolt 91 is connected to the cable 87 by means of a connecting rod 97, wherein the locking bolt 91 and the connecting rod 97 are designed to be movable relative to each other. For this purpose, the locking bolt 91 has a stepped bore 99 and the connecting rod 97 has a widened head 101 at a first end, which is slidably received in the bore 99. If the connecting rod 97 is subjected to tensile stress, the head 101 rests against the annular shoulder 103 of the locking bolt 91 and the locking bolt 91 can be retracted in the bore 93 from the advanced locking position, in which the locking bolt 91 protrudes from the end face 82 of the steering rod 23. Fig. 13 ).

[0095] A stop 105 is attached to the second end of the connecting rod 97 and is connected to an end piece 107. One end of the cable 87 is fastened to this end piece 107. The end piece 107 is connected to a compression spring 111 by means of a connecting piece 109. The compression spring 111 itself is fixed in its position in the steering rod 23 by a clamping sleeve 113 and tensions the connecting rod 97 in the Figures 13 and 14 The stop position shown is in which the stop part 105 rests against a shoulder 115.

[0096] Additionally, the locking bolt 91 is pre-tensioned by a separate spring 117, which is inserted into the space between the locking bolt 91 and the bottom of the borehole 119. The function of the spring 117 is to pre-tension the locking bolt 91 independently of the connecting rod 97 into a forward locking position, in which its front end protrudes from the end face of the connecting piece 82.

[0097] The steering rod 23 can be inserted into the Figures 13 and 14 The extreme positions shown are assumed. In the folded state of the golf trolley, which corresponds to the non-use position, the steering rod 23 assumes an angle α between 1 and 10 degrees, and in the unfolded position, which corresponds to the use position, an angle between 160 and 180 degrees with respect to the support profile 15. In this position, the locking bolt 91 can engage in a bore 121 in the support profile 15. To ensure a secure fit of the locking bolt 91, its front end is designed as a cone 123, and a sleeve 125 with a conical opening 127 is provided in the bore 121, in which the cone can engage positively (the sleeve 125 is only present in the Fig. 13 (drawn in).

[0098] If the locking bolt 91 is released from its anchoring in the bore 121 by actuating the cable 87 by pulling back the handle 89 against the spring force exerted by the spring 111, the steering rod 23 can be rotated clockwise ( Fig. 13 During this process, the connecting piece 82 rotates around the pivot pin 81 when the golf trolley is unfolded, with its curved end face 129 rotating along a semicircular surface 131 that is provided or formed on the support profile 15. The handle 89 can then be released once the trolley is in the folded position. The locking bolt 91, which is also under spring tension, then snaps into the bore 121.

[0099] Two tubular guide sections 129 and 131 are integrally formed on the handle 89, which positively engage the steering rod 23, with one of the two guide sections, in the present embodiment the guide section 131, being connected to the cable 87 (Fig. 119). The connection between the cable 87 and the guide section is made via a pin 133, which passes through two elongated holes 135 oriented longitudinally in the steering rod. The length of the elongated holes 135 limits the stroke of the handle 89.

[0100] A handle 136 is hinged to the rear end of the steering rod 23 and is adjustable about a pivot axis 137 and preferably lockable in any desired position. This allows the golfer to adjust the handle 136 to the height that corresponds to their height and is most comfortable. According to an advantageous embodiment of the invention, the grip 89 is also connected to the locking mechanism for securing a pivot position of the handle 136 relative to the steering rod 57, such that when the grip 89 is pulled back, the locking mechanism is also released and the handle, which is preferably spring-loaded, is pivoted into an end position in which the handle runs approximately parallel to the steering rod. Fig. 1 Since many solutions are known to the skilled person for how the adjustability of the bracket and the locking mechanism can be implemented, a more detailed description of these is omitted.

[0101] In the Figures 15 to 29 A second embodiment of the golf bag 53 according to the invention is shown in more detail. The golf bag 53 comprises a base section 29a with the wheel housing 40 and a top section 30a. The base section 29a and the top section 30a are connected to each other by means of several rods 141 and thus form a frame for the golf bag 53. Since the base section 29a has a smaller surface area than the top section 30a, the rods diverge slightly from bottom to top relative to each other.

[0102] The golf bag frame can be enclosed with a covering 51 made of a textile material, thus forming a container for holding golf clubs and other equipment needed for playing golf ( Figs. 22 to 25 However, it is also conceivable that the golf bag has a hard shell similar to a suitcase. In this case, rods 141 are not needed.

[0103] At approximately half the height, the two rear bars 141, which define the position of the back panel and the bottom of the golf bag respectively, are connected to each other by means of a clamp 143. Viewed from above, this clamp 143 has an approximately circular indentation 145, which serves to receive the support profile 15 when the golf bag-golf trolley unit is folded. This allows the golf bag-golf trolley unit to be built very compactly. It is conceivable to provide a preferably dimensionally stable plastic channel extending from the wheel housing 40 to the head section 30, which serves at least partially to receive the support profile 15. However, this is not mandatory. As a rule, it is sufficient for the head section to have a recess for receiving the support profile to create a very compact golf bag-golf trolley unit.

[0104] The wheel arch 40 is preferably integral with the floor section 29 and has two opposing side walls 147a, 147b, which are connected to each other on the golf bag compartment side by a connecting wall 149. At approximately half the height of the side walls 147a, 147b, lateral tabs or webs 151a, 151b with U-shaped recesses 153a, 153b are formed. The downwardly open recesses 153a, 153b serve to receive extensions 165 of the wheel axle 163 ( Fig. 21 ).

[0105] The base section 29a has a circumferential and upwardly projecting rim 155, which forms a lateral boundary for the golf club handles. Feet 157 are provided on the underside of the base section 29a, forming a standing surface for the golf bag.

[0106] On both sides of the wheel arch 40, the golf bag is narrower than the adjoining upper part of the bag (recesses 161) so that, when the golf trolley is folded, the rear wheels 27 are essentially accommodated in the periphery of the golf bag 53 ( Figs. 22 and 23 This allows the golf bag-golf trolley unit to be reduced to essentially the size of a conventional golf bag for transport purposes, provided the rear wheels can be parked in the side recesses 161 of the golf bag. As can be seen from the Figs. 23 to 25 As can be seen, the rear wheels 27 do not protrude laterally from the container above.

[0107] The front wheel 19 of the golf trolley has a wheel axle 163 which has axially outward-projecting extensions or projections 165 on both sides. The golf bag can rest on these projections 165 when the downward-oriented recesses 153a, 153b of the struts 151a, 151b are hooked onto the extensions 165 and are then held in a form-fitting manner ( Fig. 29 ).

[0108] The golf bag 53 can have side panels 167 above the wheel arch made of a somewhat firmer, particularly dimensionally stable material, which project far enough to the rear that, viewed from the side, the golf trolley is accommodated within the periphery of the side panels 165. Together with the head section and the rear wheels, these can form the support surface for the golf bag-golf trolley unit during transport (dashed line 169 in Fig. 26 , which indicates the possible contact area of ​​the golf bag).

[0109] The Figures 28 and 29Figure 1 shows a third embodiment of a golf trolley, characterized by its simplicity, compactness, and lightness. The steering rod 23 is articulated to the support profile 15 via an angled connecting piece 171 such that the pivot axis 79, which runs perpendicular to the longitudinal center plane of the golf trolley, is spaced apart from the support profile 15. This has the advantage that, when the golf trolley is folded, the steering rod 191 can run essentially parallel to the support profile 15. Specifically, the connecting piece 171 is angled at approximately 40 to 60 degrees from the longitudinal axis of the support profile 15, and the steering rod 191 is articulated at the end of the connecting piece 171 and can pivot about the pivot axis 69.

[0110] The head section 30a has a U-shaped recess 172 at the rear, viewed from above, the legs 174 of which project upwards at an angle of approximately 40 to 60 degrees. The second end of the support profile 15, on which the connecting piece 171 is arranged, is received in the recess 172 when the golf bag 53 and golf trolley are joined. U-shaped recesses 181 may be provided in the legs 174 ( Fig. 22 ), with which the head section 30a can be positively attached to the golf trolley if, for example, laterally outward-projecting pins are provided on the connecting piece 171, e.g., as an extension of the pivot axis 69 (not shown in the figures). When the golf bag is attached to the golf trolley, the pins projecting laterally from the connecting piece in opposite directions are received in the recesses 174.

[0111] For the detachable connection of the golf trolley and golf bag, additional connecting means, e.g. straps, a snap connection or the like, may be provided so that the golf bag-golf trolley unit can be carried with one hand.

[0112] The parallelogram levers 60a, 60b are arranged on the support profile 15 via a bracket 173 such that their axis of rotation 63 is located at a lateral distance from the support profile 15. Furthermore, the axis of rotation 63 is situated spatially behind the support profile 15, so that the axes of rotation of the front wheel 19 and the rear wheels are preferably somewhat spaced apart from each other when the trolley is folded and viewed in the direction of travel. This allows the golf trolley to stand freely upright even without a golf bag, as the wheels form a three-point support.

[0113] The parallelogram levers 60a,60b extend preferably parallel and at a short distance to the support profile 15 when folded and at an angle between 30 and 60 degrees to the vertical longitudinal center plane of the golf trolley when spread.

[0114] The front wheel 19 is mounted on a wheel fork 177 on the support profile 15, the fork legs 179 of which run coaxially to the support profile 15. U-shaped recesses or bearings 180 for receiving the wheel axle 163 are provided in the end faces of the fork legs 179. The fork legs 179 of the wheel fork 177 are mounted on the support profile 15 via a fork head 183. The fork head 183 has a central connecting bore 184 for receiving the front end of the tubular support profile 15 and two lateral connecting bores 186 for receiving the ends of the fork legs 179. The fork head 183, the bracket 173, and the connecting piece 171 can all be attached to the support profile 15. These components can be fixed to the tube of the support profile 15 by means of a material-locking or force-locking connection using an adhesive, welding, screws or rivets.

[0115] In the Fig. 30The individual parts of the golf trolley are shown in an exploded view. This shows that the golf trolley can be assembled from only a few individual parts. In particular, the clevis 183, the bracket 173, and the joint bracket 171 can be attached to the support profile tube 15. These parts 171, 173, and 185 can be fastened using screws, bolts, or adhesive. In the case of the joint bracket 171, it is clamped to the support profile tube 15 with clamping screws 188, and in the case of the bracket 173, with clamping screws 189. The clevis 185, on the other hand, is preferably bonded to the support profile tube 15 with adhesive, although other fastening methods are also conceivable.

[0116] The Figure 31 Figure 1 shows the golf bag-golf trolley unit from the side. It can be seen that the support profile 15 and the steering rod 23 are integrated within the periphery of the golf bag 53.

[0117] The further Figures 31 to 35Figure 171 shows in detail an advantageous embodiment of a swivel joint 189 for the articulated connection of a handle 191 to the chassis. The joint bracket 171 has a pipe clamp-like connecting piece 193 that engages the support profile tube 15 and can be tightened with the clamping screws 187. Two cheeks 195a, 195b, arranged at a distance from each other, project from the connecting piece 193 at an angle of preferably approximately 45 degrees. A swivel joint 189 is formed on the cheeks, the pivot axis 69 of which is located at a distance from the support profile 15. This has the advantage that, when the golf trolley is folded, the handle 191 can extend essentially parallel to the support profile 15.

[0118] The swivel joint 189 comprises a rotary knob 199 and a mechanism connected to the rotary knob 199 for locking the swivel joint in a position once it has been entered. The handle 191, which can pivot about the pivot point 69, is arranged on the swivel joint 189.

[0119] The pivot joint 189 has an axle 201 which is firmly screwed to the cheek 195a. The axle 201 has a socket 203a which extends through an opening 205a in the cheek 195a and has an external thread 207a. An axle flange 209 is screwed onto the opposite cheek 195b, which has a socket 203b extending through an opening 205b in the cheek 195b and having an external thread 207b. The external threads 207a, 207b of the nozzles 203a, 203b interact with locking nuts 211a, 211b, with the help of which the legs 174 of the head part 30a can be clamped between the locking nuts 211a, 211b and the cheeks 195a, 195b.

[0120] The rotary knob 199 is mounted on the fitting 207b. This knob is connected via a coupling shaft 213 and a threaded tube 215 rigidly connected to the shaft to a clamping nut 217, which can be moved back and forth by turning the rotary knob 199. The clamping nut 217 is coupled to an axially movable coupling ring 221 (axis 223) by means of the dowel pins 219. A first toothed disc 225 is fixedly mounted on the coupling ring 211. The first toothed disc 225 can interact with a second identical toothed disc 227, which is fixedly mounted via the dowel pins 229 to a rotatable joint body 231, on which the handle 191 is in turn mounted.

[0121] The locking mechanism functions as follows: The handle 191 is loosened or tightened by means of the rotary knob 199. To loosen, the rotary knob 199 is turned approximately 1.5 turns counterclockwise, and to tighten, the same number of turns clockwise. The torque generated when rotating the rotary knob 199 is transmitted via a cylindrical pin 233 to the coupling shaft 213 and the threaded tube 215, which are connected to each other by a clamping pin 235.

[0122] The clamping nut 217 is moved in the axial direction 223 via the thread of the threaded tube 215. When the rotary knob 199 is turned counterclockwise to loosen it, the clamping nut 217 moves in Fig. 35 to the left in one case and to the right in the other.

[0123] The clutch ring 221 is connected to the clamping nut 217 by means of the two cylindrical pins 219. The first toothed washer 225 is screwed onto the clutch ring 221.

[0124] The coupling ring 221 is in turn connected to the axle 201 via dowel pins (in the Fig. 35 (not visible) so that it can only move in the axial direction 223 and any applied torque is transferred to the axis 201.

[0125] The axle 201 is screwed to the cheek 195a, which is fixedly connected to the chassis or head section, and thus any applied torque can be transferred to the chassis.

[0126] In the tightened or closed state, the toothed disc 225 and the toothed disc 227 are positively connected to each other. If a torque is now applied to the joint body 231 via the handle 191, this is transmitted to the toothed disc 227 via the cylindrical pins 229. Due to the positive connection between the two toothed discs 225 and 227, the torque can thus be derived, as described in the previous section.

[0127] If the rotary knob is now turned counterclockwise, the parts 217, 221, 219 and 225 described above move axially to the left. After 1.5 revolutions, the teeth of the two toothed discs 225, 227 are no longer engaged with each other and the joint body 231, to which the handle 191 is mounted, is freely rotatable.

[0128] The golf trolley and golf bag are used as follows: On first use, the starting position is the folded golf trolley 11 and the separate golf bag 53. The golf trolley is first stood upright, the locking mechanism of the steering rod 23 is released, and then the steering rod is swung away from the support profile. At the same time, the rear wheels are swung into the splayed position. The steering rod 23 is adjusted to a height appropriate to the golfer's height and then locked in place ( Figs. 28 and 29 The golf bag is then placed on the golf trolley by inserting the axle extensions into the recesses. The golf bag can then be pivoted towards the support profile and locked onto it using a form-fit and / or force-fit mechanism.

[0129] After the golf trolley is initially set up and the golf bag attached to it, they can remain permanently together for further use (playing, transport in a car, and storage). This is because, firstly, the golf bag with the trolley is only slightly larger than a conventional golf bag, and secondly, because the golf trolley, made of lightweight materials, is very light. In other words, the golf bag and trolley form a single unit, but with the advantage over the integrated golf bag trolleys mentioned earlier that the trolley and bag can be separated again at any time with a single movement, for example, if the golf trolley is to be used by different people. It is also conceivable that various manufacturers could produce golf bags for the inventive golf trolley according to the proposed concept.

[0130] To fold the golf bag-golf trolley unit, the golfer first releases the locking mechanism on the handlebar, pivots it towards the support profile, and then locks it again. The golf bag-golf trolley unit is then in a vertical position. When tilted, the golf bag-golf trolley unit can be pushed or pulled to save space on the way from the course to the parking lot. Unlike the golf bag carts mentioned earlier, the golf bag-golf trolley unit does not need to be carried, as the wheels of the golf trolley still protrude from the periphery of the golf bag when folded. To load it into the trunk of a car, the golf bag-golf trolley unit is laid down (handlebar at the bottom), the entire unit is lifted, and placed in the trunk. A carrying handle may be provided approximately in the middle of the golf bag for carrying the unit (not shown in the illustrations).

[0131] In the more elaborate embodiment of a golf trolley with a locking mechanism according to the Figures 11 to 14 To right the golf trolley, the golfer first unlocks the handle 23 and then pivots it upwards until the snap mechanism automatically engages upon reaching the end position, locking the handle in place. Simultaneously with pivoting the handle 23, the golf bag-golf trolley unit is tilted and supported on its rear wheels. The handle 23 can also be unlocked using the movable handle 89. The handle, if height-adjustable, can then be adjusted to the appropriate height.

[0132] To fold the golf bag-golf trolley unit, the golfer first grasps the handle 89, pulls it back, and thereby releases the locking mechanism of the operating rod 23. The steering rod 23 is then swung downwards, simultaneously bringing the golf bag-golf trolley unit into an upright position. In this position, the steering rod can be locked again, either by a separate snap mechanism or by means of the spring-loaded bolt 91. When the folded golf trolley is tilted backwards, it can be rolled. As a rule, the combined golf bag-golf trolley unit is transported together. Using a handle on the golf bag, the golf bag-golf trolley unit can be lifted and stored in the trunk of a car.

[0133] The invention relates to a golf bag for holding multiple golf clubs, characterized in that the base of the golf bag incorporates a wheel housing for the front wheel of a three-wheeled golf trolley. The golf bag is designed to be attached to a three-wheeled golf trolley. The golf trolley has a front wheel with an axle that features outwardly projecting axial extensions on opposite sides of the front wheel, forming a support for the golf bag. One end of the golf bag can be secured to the front wheel by a positive fit, and the other end can be secured to the support profile of the golf trolley by a positive and / or frictional fit.

[0134] The terms "front wheel" and "rear wheels" used in the description are not to be understood as limiting, since the golf trolley according to the invention can be pushed (the usual case) or pulled. Furthermore, the individual features can be implemented in different combinations on a single golf trolley. legend
