Description

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

The invention relates to a golf bag according to the preamble of claim 1, a golf trolley according to the preamble of claim 17, and a golf bag/golf trolley unit with a golf bag and a golf trolley according to claim 33.

State of the art

Without a motorized golf caddy, golfers usually cover several kilometers in a game of golf. You carry up to 14 different golf clubs, which are approved for a maximum of one round of golf, in a golf bag designed for this purpose. To avoid having to carry the golf bag and clubs all the time, the player typically carries the bag with them on a multi-wheeled cart. State of the art are two- and three-wheeled golf carts, often referred to as trolleys, which are conventionally pulled behind you or, more recently, increasingly pushed in front of you as three-wheeled push trolleys.

Examples of golf carts are disclosed in documents US 2013/0234418A1, US 2012/0261908, US 2012/0112436A1. The golf carts mentioned are characterized by the fact that the golf case and the chassis are separate units that are only connected to one another when the sport is practiced. The disadvantage of these golf carts is that they are often not very stable, usually take up a lot of space during transport and a lot of time is needed to set up and fold them together.

A newer generation of golf trolleys has the wheels and the tongue attached directly to the golf bag, i.e. the wheels and tongue are integral with the golf bag and are thus comparable to a trolley case on which two or four wheels are fixed. Integral therefore means that the golf bag and chassis form a unit, also referred to below as the golf bag trolley, and cannot be separated.

European patent EP 0055873 Bl discloses a two-wheeled golf cart with a drawbar for pulling the golf cart and a container divided into several compartments. The wheel frame is partly non-positively connected to the container and arranged in such a way that when the wheel frame is in the active position, the weight of the container is distributed evenly and the free end of the drawbar is relieved. A first department of the golf cart described is used to accommodate the wheel frame and its operating mechanism in which inactive position, another compartment for housing golf clubs and a third compartment for housing accessories of various kinds.

If the bogie is to be pivoted from its inactive stowed position to the active transport position, a locking device is released, whereby the bogie consisting of two legs rotates about a pivot pin under the pressure of a spring and pivots out of the container. When the drawbar is swung up, the articulated arms and thus the legs of the wheel frame are spread apart. A disadvantage of this golf cart is that the wheel frame is accommodated in the center of the container when not in use, which means that valuable space for arranging the golf clubs inside the container is lost.

EP 2581 291 A2 discloses a four-wheeled, collapsible golf cart which can also be opened or folded from a position of non-use into a position of use. The golf cart includes a golf bag cart assembly and a pouch attachable to the golf bag cart assembly. At a second end, the golf bag trolley unit has two front wheels which can be rotated about a fixed first axis of rotation and are spaced apart from one another. At a distance from these are two rear wheels that can rotate about a second axis of rotation. These can be pivoted from a folded position to an unfolded or spread position. In the folded position, the wheels hold the golf cart assembly in a horizontal position with the second pivot axis at the first end of the golf bag cart assembly.

The golf bag cart unit has a rear wheel unit that is attached to the body of the golf bag cart unit by a fastener. The rear wheels of the rear wheel unit are articulated via a cantilever tube and a rod to a sliding block which can be displaced between two extreme positions. In addition, a tie rod connects one point of the boom tube to the slide block. If the sliding block is now shifted from one extreme position, in which the rear wheels are close together, towards the other extreme position, the pull rod pulls the rear wheels apart. This movement is additionally supported by gas springs. The American patent application published under no. US 2013 / 0234420 A1 discloses a three-wheeled, combo golf bag trolley which can be easily expanded and collapsed and has the shape of an offset parallelogram. The golf bag trolley consists of several sub-assemblies, namely an outer frame, a parallelepiped-shaped housing for the clubs, a front and a rear wheel unit, and a handle. The outer frame includes a base plate, which is held by two lateral beams and encloses an angle of approx. 120 degrees with them. Also attached to the side beams is a front frame bracket that supports the golf club case. The case for the golf clubs consists of individual tubular cases which extend in the longitudinal direction of the case. The front wheel assembly is attached to the base via fork arms and is pivotable via a pivoting mechanism from a position in which the fork arms are an extension of the base to a position in which the fork arms are positioned with the wheel beneath the golf club case.

The rear wheel unit consists of two rear wheels, each rotatably mounted on an axle rod. The axle rods are each articulated via a lever on the side beams of the frame and can be pivoted about a pivot axis. A turntable with two notches is arranged on the pivot axis, in which a stop post can engage in the two extreme rotational positions.

In an alternative embodiment, the golf bag cart consists of a golf club case, a transport assembly that facilitates transportation around the golf course, and an extension assembly that cooperates with the other two assemblies to fold and unfold the golf bag cart.

The golf club case is formed by a baseplate, a rigid collar, and a thermoformed backplate connecting the baseplate and collar. Portions of the inner frame and bottom plate are formed toward the front of the golf club case to define a wheel cavity at the center. The transport assembly includes a front wheel supported by two arms. The arms are attached to the floor pan at a forward pivot point and are pivotable about a pivot axis from an in-use position in which the front wheel is located in front of the floor pan to an inoperative position in which the front wheel is received in the wheel cavity.

The rear wheels are each attached to the back plate of the golf club case via two parallelogram levers. One of the two parallelogram levers is connected to the swiveling handle via a connecting rod. When the handle is pivoted from the position of non-use to the position of use, the rear wheels are also extended to the position of use. A ramp on the swivel joint ensures that the wheels also move apart when extending.

The disadvantage of this golf bag trolley is that several brackets are required to open or fold the golf bag trolley. The front wheel must first be brought into the position of use and then the rear wheels. Also, the golf bag and the transport assembly are a unit and are not designed as disassemblable units. Accordingly, the weight of this golf bag trolley is relatively high.

American patent US 8,764,030 discloses a sports bag assembly with an integral wheeled transport system. What is special about the sports bag arrangement of US Pat. No. 8,764,030 is that the transport system can be stowed within the geometry of the sports bag and positioned with a single mechanical movement. The transport system is deployed by pulling a handle, which causes a front wheel to extend in the opposite direction and two rear wheels to be spread apart. For this purpose, first toothed racks are formed on the U-shaped handle, each of which is connected via a gear wheel to a second toothed rack on which the front wheel is arranged. If the first racks are moved in one direction, the second racks move in the opposite direction with the front wheel. The movement of the first and second racks is relative to a stationary bracket of the athletic bag assembly. The rear wheels are arranged on pivotable legs, which are each connected to the first toothed racks in an articulated manner via an arm. If the handle of the sports bag arrangement is pulled upwards, the legs spread with the rear wheels. So that the rear wheels can be accommodated in a recess in the sports bag in the rest position, they are also pivoted.

The sports bag described with an integral transport system has the advantage that it is compact and easy to stow away due to its size and can be set up or folded up with a single mechanical movement. The disadvantage is that the transport system has a very complex design and has many articulated connections, which has a negative effect on its stability. Another disadvantage is that the sports bag has to be carried in the folded position because all the wheels are retracted. The space required for arranging the wheels in the rest position is no longer available for arranging the golf clubs, which increases the overall length of the sports bag.

EP 2819908 relates to a golf trolley and golf bag combination for carrying a set of golf clubs. The combination can be converted from a transport or storage condition to an operational condition in which it can be driven around a golf course. The golf trolley has a chassis with a body and an elongated base extending down to a center wheel. The base plate has a 90 degree upcurved extension at the bottom that serves as a stop for a golf bag. A battery pack can be placed on the extension if the golf trolley is motorized. The center wheel protrudes from the lowest part of the base plate so that the golf trolley stands upright on both the center wheel and the two coaxial rear wheels. In addition, the middle wheel is accommodated in a small wheel housing, so that the wheel cannot touch the golf bag.

The center wheel of the golf cart described has a very small diameter compared to the other two wheels. The disadvantage of this is that smaller obstacles, such as stones, make it difficult to move the golf trolley. The bag on this product is designed to be an integral part of the combination, but in an alternative form it is detachable from the trolley and attachable to the chassis by suitable fasteners. The golf trolley of EP 2819 908 is an all-in-one golf cart which, in its folded position, is comparable in size to a traditional golf bag and fits securely in the back seat of a car.

US 10471 314 Bl discloses a multi-wheeled golf cart that combines the functionality of a conventional cart and a golf bag in a single piece of equipment. The trolley is designed to fold into two positions: a first folded position for storage and transport, and a second extended position for walking. Through the use of axles and brackets, the two rear wheels are mounted on trailing arms, which then mount to the lower chassis brackets. 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, which in turn is attached to the upper chassis. The push rod assembly attaches to the upper chassis through the use of two mounting collar brackets.

What the golf bag trolleys available on the market today have in common is that they are often constructed in a complicated manner and setting up or Unfolding the golf bag trolley requires several movements. Women in particular often have trouble getting the golf bag trolley ready for use in a reasonable amount of time. Also, their weight is usually so high that women have trouble tying up these golf bag trolleys.

The present invention relates to a golf bag and a separate golf trolley (transport assembly) which can be easily combined into a golf bag/golf trolley unit and can also be transported as such.

It is therefore the object of the present invention to provide a golf bag/golf trolley unit which has both the advantageous properties of a sports bag arrangement with an integrated transport system and the advantageous Features of a golf bag in terms of size. This means that the golf bag and golf trolley should be able to be releasably connected to one another with as few movements as possible and, when combined, should be very compact and only slightly heavier than a golf bag alone. The aim is for the golf bag and golf trolley to be transportable as a golf bag/golf trolley unit, although they are designed as separate units and can be easily dismantled. The golf bag/golf trolley unit should not be larger than a conventional golf bag. Another goal is that the golf trolley can be set up or set down with a single movement. can be folded up. Also, the golf bag-golf-trolley unit consisting of a separate golf bag and golf trolley should not have to be carried even when folded, ie it should be able to be rolled. When not in use, the golf bag/golf trolley unit should be as compact and space-saving as possible. Another goal is to further develop a golf trolley so that the chassis is as stable as possible. The combined golf bag/golf trolley unit should also have the lowest possible weight. Another goal is that the golf bag/golf trolley unit can be guided as comfortably as possible by a golfer. It would also be advantageous if the outfit of the golf bag could be changed.

The invention relates to a golf bag for detachable attachment to a golf trolley, with a receiving space for a plurality of golf clubs, comprising a base part, a head part, a support frame that connects the base part to the head part, and a cover arranged on the support frame, preferably made of a textile or rigid material surrounding the golf club accommodation space, the golf bag being adapted to be releasably attached to at least two points on a three-wheeled chassis.

According to the invention, the golf bag is characterized in that a wheel case for receiving the front wheel of a three-wheeled golf trolley is provided in the bottom part of the golf bag and the bottom part is formed. to support yourself on the front axle of the three-wheeled golf trolley. The provision of a wheel housing integrated in the golf bag has the advantage that a corresponding trained chassis of a golf trolley can be accommodated for the most part within the periphery of the golf bag. The golf bag can also 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” is understood to mean that the chassis of the golf trolley is essentially covered by the cover of the golf bag when viewed from the front or from the side.

The wheel housing is advantageously a slot-shaped accommodation space. This is slightly wider and higher than the front wheel to be picked up and extends from the back to about the middle of the floor part or beyond. This has the advantage that there is still space for the golf club handles on the side and in front of the wheel housing.

Preferably, the wheel housing has two opposite side walls, on which are formed laterally rearwardly projecting webs at about half the height, which have aligned recesses for receiving the front wheel axle of a golf trolley. This allows the axis of rotation of the wheel to pass behind the wheel arch and increases the footprint of the unified golf bag and golf trolley unit, providing good standing when the chassis is folded. Then the tread of the wheel can be approximately aligned with the base of the floor part.

Feet forming a standing surface are expediently provided on the underside of the base part in order to form a stable support surface.

The axial distance between the standing surface of the floor part and the recesses for the wheel axle is preferably dimensioned such that the running surface of a front wheel accommodated in the wheel housing is essentially flush with the standing surface.

It is advantageous that the bottom part has a peripheral edge. This allows the racquets to be placed around the wheel arch. In addition, the fabric cover can be fixed at the edge.

According to an advantageous embodiment, a head part is provided opposite the base part, in which a recess for receiving the support profile a golf trolley is provided. 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.

The head part is advantageously connected to the base part by means of several rods. The bottom part, the top part and the bars form a framework for the golf bag that can be enclosed with a cover.

Advantageously, the bars located at the rear of the golf bag define a recess for receiving part of the chassis of a golf trolley. As a result, part of the golf trolley chassis, e.g. an elongated support profile, can be accommodated in the recess.

Appropriately halfway up, a clamp is provided which connects two or more rods and defines an approximately semicircular indentation when viewed from above. The supporting profile of the golf trolley, which is formed from a tube, can extend in this indentation. This means that the support profile can run in an elongated channel of the golf bag that is open to the rear.

An alternative embodiment provides that a channel open to the outside (rear) for receiving the elongated support profile (15) of a golf trolley is provided adjoining the wheel housing for the front wheel. The channel can, for example, be a plastic profile that connects the bottom part and the top part to one another. The head part can also have a semicircular indentation for receiving the tubular support profile.

Advantageously, the channel for the support profile runs essentially in the periphery of the cover of the golf bag. This means that the support profile of the golf trolley is practically invisible when viewed from the side. As a result, the golf bag/golf trolley unit consisting of the golf bag and golf trolley is very compact.

The golf bag preferably has an indentation on each side for receiving the rear wheels of the golf trolley, so that the rear wheels of a three-wheeler are also arranged within the periphery of the cover when the golf trolley is in the folded state (seen from the front or rear). Advantageously, the cover of the golf bag has side parts that project laterally backwards. These side panels can be made of a slightly stronger material so that the golf bag can rest on the side panels when being transported in a vehicle. In any case, it is useful if the support profile and the parallelogram lever do not protrude beyond the side parts when the golf trolley is folded (seen from the side).

The head part expediently has subdivisions for accommodating different golf clubs, so that the golf clubs can be arranged in a clear manner.

It is conceivable that a wheel is already permanently mounted in the wheel housing of the golf bag. Accordingly, a golf trolley would only have to have two expandable rear wheels.

The subject matter of the present invention is also a three-wheeled golf trolley for holding a golf bag, with a chassis comprising a front wheel and two rear wheels, the rear wheels each being articulated on the chassis by means of two parallelogram levers and being movable 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, the rear wheels being movable through the steering rod from the transport position to the driving position and vice versa.

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 Ver longer ments of the wheel axle are not known. 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 connection. A fork with U-shaped recesses is advantageously provided or formed on the support profile, which serve to accommodate the front wheel axle. The fork is preferably arranged in a fixed and non-rotatable manner on the support profile.

It is advisable for the axle of the front wheel to protrude beyond the fork on both sides by a certain distance, for example by 0.5 to 3 cm, so that a golf bag can be supported or placed on it. can be hung.

The steering rod is advantageously arranged via a connecting piece on the support profile in such a way that the pivot axis is located a specific distance behind the support profile. This has the advantage that the support profile and handlebar are aligned essentially parallel to one another when folded and the axis of rotation of the front wheel runs at a distance from the support profile. This makes it possible to lift the golf bag arranged on this from the ground by tilting the golf trolley backwards and to move the golf trolley away. The rear wheels are in contact with the ground.

Advantageously, at a distance from the second end of the support profile, connection means are provided for producing a positive and/or non-positive connection with a golf bag. With the help of a two-point connection, a golf bag can be reliably attached to the carrying profile of the golf trolley. A technically simple solution provides that the golf bag can be attached to the support profile by means of a belt or rubber band. The strap or the rubber band can be part of the golf trolley or golf bag.

The parallelogram levers are preferably pivotably arranged on a holder in such a way that the pivot axis runs at a short distance laterally and behind the support profile. This has the advantage that when folded, the axis of rotation of the rear wheels runs behind the support profile.

The wheel housing is advantageously designed as a receiving slot. This is so large that between about 40 and 50% of the cross-sectional area of the front wheel of the golf trolley has room.

The bottom part is advantageously designed to be supported on an extended axle of the front wheel of a three-wheeled golf trolley. Advantageously, the wheel housing has two opposite sides, on which webs are formed at about half the height, which have aligned recesses for receiving a front wheel axle. This allows the bottom part of the golf bag to be hung on the axle of the front wheel and a form-fitting connection to be established. Due to the construction described, the running surface of the front wheel can be flush with the standing surface of the floor part, so that the golf bag/golf trolley unit is supported on the floor with the floor part and the front wheel. This means that the golf bag/golf trolley unit has good stability even when folded and does not immediately tip over.

The accommodation space is expediently designed to accommodate between 30 and 70%, preferably between 40 and 60% and particularly preferably between 40 and 49% of the cross-sectional area of the front wheel. This means that most of the front wheel protrudes from the wheel housing.

Advantageously, the floor part has a substantially flat floor and the wheelhouse for the front wheel extends approximately perpendicular to the floor. In this way there is still enough space for arranging a plurality of golf clubs.

According to a preferred embodiment, an outwardly open channel for receiving the support profile of a golf trolley is provided adjoining the wheel housing for the front wheel. This has the advantage that the channel for the support profile can essentially run in the periphery of the cover, which ensures that the combined golf bag/golf trolley unit is compact.

Feet are expediently provided on the underside of the base part. This ensures that the combined golf bag/golf trolley unit stands up well when folded. The base part is preferably trough-shaped with low, circumferential side walls. Advantageously, a head part is provided opposite the bottom part, which is connected to the bottom part by means of several rods. This is an ultra-lightweight construction, especially when the bars are made from a carbon fiber reinforced plastic. The head part preferably has subdivisions for accommodating different golf clubs, so that they can be clearly arranged and easily removed.

According to another aspect of the invention, the front wheel of the golf trolley is fixed in the wheel housing of the golf bag.

The present invention also relates to a three-wheeled golf trolley for accommodating a golf bag with a wheel housing provided in the bottom part of the golf bag with an elongate, in particular tubular, support profile, a front wheel which is arranged at a first end of the support profile, a handlebar which has a first end on the is articulated at the second end of the support profile, and can be pivoted in a plane from a first position, in which the connecting rod rests on the supporting profile, into a second position, in which the connecting rod assumes an obtuse angle with the supporting profile,

Locking means to fix a once assumed position of the steering rod relative to the support profile, two rear wheels, which are articulated by means of two parallelogram levers on opposite sides of the support profile, two struts, one end of which is attached to at least one of the parallelogram levers and the other end to the Handlebars are articulated in such a way that the rear wheels can be moved from a narrow transport position into a spread driving position and vice versa when the handlebars are 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 particularity that the front wheel has an axle whose axial extensions on opposite sides of the front wheel form a support for a golf bag. As a result, a suitably designed golf bag can be hung on the golf trolley and form a compact unit with it. The golf trolley according to the invention is generally pushed, so that the “middle wheel” is referred to as the “front wheel” and the other two wheels as “rear wheels” in the description. It is clear to the reader that the golf trolley can of course also be pulled. A fork with U-shaped recesses is advantageously provided or formed on the support profile, which serve to accommodate the front wheel axle.

Advantageously, the axle of the front wheel projects beyond the fork by a certain distance on both sides.

According to an advantageous embodiment, the steering rod is arranged on the support profile via a connecting piece in such a way that the pivot axis is located a certain distance behind the support profile. This has the advantage that the support profile and handlebar can run essentially parallel to one another when the golf trolley is in the folded state.

Advantageously, at a distance from the second end of the support profile, connection means are provided for producing a positive and/or non-positive connection with a golf bag, so that the golf bag and golf trolley can form a unit that can be transported together, so that the advantages of an integrated golf bag trolley are realized.

Advantageously, the parallelogram levers are pivotably arranged on a bracket in such a way that the pivot axis runs at a short distance laterally and behind the support profile. This has the advantage that the rear wheels are arranged at a short distance from the supporting profile when folded.

Advantageously, the rear wheel unit can be pivoted about an axis of rotation provided on the chassis, in particular the support profile. This allows the rear wheel unit to be quickly brought into the position of use.

The chassis expediently comprises a preferably elongate support profile. The provision of a central support profile extending in the longitudinal direction of the golf trolley has the advantage that this gives the golf trolley great stability. However, it is also conceivable that a frame construction is used instead of a rod-shaped support profile, with the rest of the construction remaining the same.

In a further embodiment, the device for guiding the golf trolley is arranged on a handlebar which is pivotably articulated on the support profile and is also articulated to the rear wheel unit. This embodiment has the advantage that pivoting by Ver the handlebar from a non-use position (folded position) in which the handlebar on the back of the golf trolley, respectively. almost or completely rests against the rear wheel unit and a position of use in which the steering rod occupies an angle of up to 20 degrees to the longitudinal axis of the support profile, can be brought into a ready-to-drive, unfolded position. When setting up the golf trolley, the handlebar is preferably pivoted between about 130 degrees and 180 degrees.

The rear wheels are preferably articulated directly or indirectly to the support profile or frame by means of a wheel support. This ensures great stability for the entire golf trolley.

Advantageously, the device for guiding the golf trolley includes a handlebar, the handlebar being articulated on the support profile. This construction ensures high stability of the golf trolley with low weight.

According to a particularly advantageous embodiment, the steering rod and wheel supports are mechanically coupled to one another by means of a strut. This results in good support for the guide device because loads can be transferred directly to the wheel supports via the struts.

Advantageously, the device for guiding the golf trolley includes a bracket that is rotatably mounted on the handlebar and is therefore adjustable in height. The bracket can thus be adjusted to different heights according to the size of a golfer.

The front wheel is expediently arranged so that it can rotate freely at the front end of the support profile. This also serves to ensure the stability of the golf trolley if the front wheel is arranged directly on the support profile. For this purpose, the support profile can have a wheel fork similar to the bicycle fork of a bicycle in order to mount the front wheel. The axis of rotation of the front wheel advantageously runs below and at a distance from the longitudinal center line of the support profile. Preferably, in the folded position, the rear wheels are laterally close to the bottom portion of the container. For this purpose, the bottom part can have lateral indentations or niches in which the rear wheels are partially or preferably completely accommodated in the non-use position, so that they do not protrude laterally beyond the golf bag, ie the wheelbase is not wider than the golf bag. This is a space-saving design and ensures compactness of the golf bag and golf trolley unit.

In the non-use position, the rear wheels are advantageously at least partially accommodated in the outer contour of the base part and/or the cover in a top view of the lying golf bag/golf trolley unit. The more the rear wheels are accommodated in the outer contour of the casing, the more compact the entire golf bag/golf trolley unit is.

The cover advantageously connects the bottom part and the top part to one another and has a front and a back, as well as two side surfaces connecting the front and back. The cover can be exchangeable and made from different materials such as plastic, textile, shell, etc.

The base part expediently has a bevel in order to improve the ground clearance of the golf trolley in the position of use. This bevel is between the back and the bottom of the base piece. Depending on the position of the front wheel in the floor part, the bevel can be more or less pronounced.

If the axes of rotation of the rear wheels on the one hand and the axis of rotation of the front wheel on the other hand are spaced apart in the non-use position, the golf trolley can stand upright without the bottom part having to be supported on the support surface. However, it is just as conceivable that the container is supported on the ground when the golf trolley is in the upright, folded position. In this way, the golf trolley can stand on the front wheel and/or the rear wheels in the upright, folded position and be supported by the bottom part, so that the golf bag/golf trolley unit can assume a stable position. The rear wheel unit is advantageously articulated on the chassis in such a way that when it is pivoted from the non-use position into the use or driving position, the wheel supports are spread apart. This has the great advantage that the stability of the golf bag/golf trolley unit is improved and tipping to the side is hardly possible, even on hilly terrain. The rear wheels can expediently be spread to approximately twice the width relative to the basic position (non-use position).

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 approximately at right angles to the carrier.

A plurality of openings for inserting the golf club shafts are expediently formed in the head part, so that the desired number of golf clubs can be carried along. So that the golf clubs can be easily removed from the container and a visually tidy picture is created, the golf club heads are preferably positioned in the head part. For this purpose, a plurality of openings can be provided in the head part. So that the golf clubs are guided within the container, individual tubes can preferably be connected to the underside of the head part, which can extend to the bottom part.

A bracket is preferably provided which is articulated at the rear (distal) end of the handlebar and can be fixed in various positions. This has the advantage that the bracket can be adjusted to the size of a user of the golf trolley.

In a further embodiment, a handle is arranged on the handlebar so that it can move in the longitudinal direction and is mechanically connected to a bolt. This allows the steering rod to be unlocked by pulling the handle back far enough for the bolt to disengage from the latch. The bolt is advantageously biased into a locking position by means of a spring element. This has the advantage that the bolt can engage automatically when the steering rod is pivoted and the handle is released. A snap mechanism is expediently provided for latching the handlebar in the non-use position. The actuating rods can thus be releasably fixed in the position of use as well as in the position of non-use.

The first embodiment of a golf trolley 11 shown in Figures 1 to 10 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 standing unit 20 with one at the rear end 21 of the support profile articulated handlebar 23 and arranged between the front and the rear end 17, 21 rear wheel unit 25 with two rear wheels 27 and two struts 28. On the golf trolley 11, a golf bag 53 is releasably attached. The golf bag 53 has a base part 29 and an opposite head part 30, which are connected to one another via a framework to be described in more detail below. These components and their interaction are explained in more detail below.

When the golf bag is loaded, the bottom part 29 accommodates the grip ends of golf clubs 31, also referred to as “iron” in golf jargon. The bottom part 29 is part of the golf bag and comprises a bottom 33, a front 35 and a back 37 and two side surfaces 39 which connect the front and back sides 35, 37 to one another (FIG. 1). The front and back sides 35, 37 and the two side surfaces 39 extend essentially at right angles to the base 33 and form a peripheral, upwardly protruding collar which has a height of between 5 and 10 cm relative to the base 33. In the middle of the floor part 29 there is a slit-shaped wheel housing 40 which is open to the rear and below and which accommodates slightly less than half the cross-sectional area of the front wheel 19 (FIGS. 1 and 2). The wheel housing 40 and the diameter of the front wheel 19 are matched to one another in such a way that the running surface of the front wheel is approximately flush with the underside of the floor part 29 .

A bevel 41 is formed between the back 37 and the bottom 33 of the bottom part 29, so that in the driving position of the golf trolley there is sufficient ground clearance between the bottom part 29 and the support surface 43, respectively. lane available is. The provision of a chamfer 41 is necessary when the wheel axle is located a short distance from the rear 37 within the floor part 29.

The head part 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 (Fig 7 and 8). Instead of a molded part 45, however, a circular, semicircular or U-shaped frame, preferably made of a dimensionally stable plastic, can also be provided. Arranged on the bottom and top parts 29, 30 is a cover shown in dashed lines in FIGS. 5 and 6, which together with the bottom and top parts 29, 30 defines a container for the golf clubs 31. The cover, advantageously made of textile material, is detachably connected to the base and head parts 29, 30, preferably by means of rivets, press studs, a Velcro fastener, clamping elements or the like. This has the advantage that the cover can be replaced in the event of damage or if the appearance of the golf bag needs to be changed for fashion reasons.

The rod-shaped supporting profile 15 of the golf trolley has at the front end 17 an extension 55 which is angled downwards in the position of use and on which the front wheel 19 is articulated and can be rotated about an axis of rotation 57 (FIG. 10). Due to the angling of the supporting profile 15 downwards, the axis of rotation 57 of the front wheel 19 is at a distance from a longitudinal center line 58 (FIG. 10) passing through the supporting profile. As a result, the recess 41 in the base part 29 can be somewhat smaller because the front wheel dips less into the container and there is therefore more space overall for stowing the golf clubs.

The rear wheel unit 13 of the golf trolley includes two separate wheel suspensions on which the two rear wheels 27 are freely rotatably arranged. The wheel suspensions each include a wheel support 59 which is connected to the support profile 15 by means of a joint 61 and can be pivoted about a pivot axis 63 . The joint 61 for the articulation of the wheel supports 59 is seen in the longitudinal direction of 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 an axis of rotation 65. The wheel support 59 comprises two individual parallelogram levers 60a, 60b which are spaced apart from one another and which can be pivoted about the pivot axes 63. Due to the fact that the two parallelogram levers 60a, 60b are articulated at different points, the wheels are pivoted away from the supporting profile in parallel relative to one another when they are unfolded, so that they are also parallel to one another in the position of use.

The handlebar 23 for folding or unfolding the golf trolley is articulated at the first, rear end of the support profile 15 and can be pivoted about a pivot axis 69 . The struts 28 provide an articulated connection between the steering rod 23 and the wheel supports 59 via the pivot points 73 and 75. If the steering rod 23 is pivoted, then the wheel supports 59 are also forced to pivot ver. In one extreme position of the righting 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 In the extreme position, the wheel supports 59 describe approximately a right angle to the support profile 15, and the steering rod 23 extends at an angle a of approximately 15 degrees to the support profile 15 (FIG. 14). In this position, the support profile 15 and the golf bag 53 arranged on the support profile 15 assume an angle of between approximately 40 and 50 degrees to the road surface 43 .

FIGS. 7 and 8 show the arrangement of the golf clubs 31 in the golf bag 53 in more detail. A total of nine holes 47' are provided in the molding 45 for golf clubs 31 with a normal shaft length, which are grouped in a "U". Four further holes 47" are provided below the nine holes 47' mentioned closer to the outer edge of the molding 45. These holes 47" are reserved for overlong golf clubs.

Tubes made of plastic or a textile material can be connected to the holes 47' and 47" on the underside of the molded part 45, in which the golf club shafts 49 are guided or accommodated. These tubes are shown in Fig. 8 for reasons of representation and clarity however not drawn in. As from the As can be seen in Figures 1, 5 and 8, the shafts of the top three golf clubs 31' extend substantially parallel to the longitudinal centerline 58 (Figure 10) of the support profile 15, while the other six golf clubs 31' of the U-shaped arrangement are towards the center inclined so that they come to rest in the container in the space between the wheel housing 40 provided for the front wheel 19 and the rear wheels 27 . The shafts 49 of the overly long golf clubs 31", on the other hand, use the remaining space between the cover (not shown) and the total of six golf clubs 31' arranged at the side and extend in the container 53 from the top back at an angle down to the front when the golf bag/golf trolley unit is vertical This sloping arrangement of the golf clubs means that up to an additional 5 cm shaft length can be accommodated within the case. The terms "top" and "back" refer to the position of use and direction of travel of the golf bag/golf trolley unit and are not intended as limiting features The back of the golf bag is where the front wheel of the golf trolley protrudes from the bottom part.

In the figures 11 to 14 the locking mechanism for the handlebar 23 is shown. The locking mechanism ensures that the handlebar 23 is securely fixed when the golf trolley is folded out, at an angle of between approximately 10 and 30 degrees to the support profile 15. a single movement from the folded (non-use position) to the unfolded state (use position) can be converted. This is in contrast to the integrated golf bag trolley mentioned at the beginning, where several movements are required to set them up. In order to make setting up the golf trolley as easy as possible, a swivel joint 79 is formed at the rear end 21 of the support profile 15 . The rotary joint 79 has a pivot pin 81 on the support profile 15 . The steering rod 23 is placed on the pin 81 and has a somewhat thicker connecting piece 82 with a bore 83 for this purpose. The handlebar 23 is tubular with a channel 85. In this channel 85 extends a cable 87, which is a mechanical connection between a handle 89, which is displaceably mounted on the handlebar 23, and a movable Locking pin 91 produces, which is received in a front blind hole 93 of the steering rod 23.

The locking bolt 91 is connected to the cable pull 87 by means of a connecting rod 97, the locking bolt 91 and the connecting rod 97 being designed to be movable relative to one another. For this purpose, the locking bolt 91 has a stepped bore 99 and the connecting rod 97 has a widened head part 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 part 101 rests against the annular shoulder 103 of the locking bolt 91 and the locking bolt 91 can be pulled back in the bore 93 from the advanced locking position in which the locking bolt 91 protrudes from the front end 82 of the steering rod 23 (Fig- 13).

A stop part 105 which is connected to an end piece 107 is placed on the second end of the connecting rod 97 . At this end piece 107 one end of the cable 87 is fixed. The end piece 107 is connected to a compression spring 111 by means of a connecting part 109 . The compression spring 111 itself is fixed in its position in the steering rod 23 by a clamping sleeve 113 and prestresses the connecting rod 97 into the stop position shown in FIGS.

In addition, the locking bolt 91 is prestressed by a separate spring 117 which is inserted into the space between the locking bolt 91 and the bottom 119 of the drilled hole. The spring 117 has the function of preloading the locking bolt 91 independently of the connecting rod 97 into an advanced locking position in which its front end protrudes from the connecting piece 82 at the front.

The handlebar 23 can assume the extreme positions shown in FIGS. In the folded state of the golf trolley, which corresponds to the position of non-use, the handlebar 23 assumes an angle a of between 1 and 10 degrees and in the unfolded position, which corresponds to the position of use, an angle of between 160 and 180 degrees with respect to the support profile 15. The locking bolt 91 can engage in a bore 121 in the support profile 15 when the golf trolley is in the position of use. In order to ensure that the locking bolt 91 To ensure this, its front end is designed as a cone 123, and a sleeve 125 with a cone-shaped opening 127 is provided in the bore 121, in which the cone can positively engage (the sleeve 125 is only shown in FIG. 13).

If the locking pin 91 is released from its anchorage in the bore 121 by operating the cable 87 by pulling back the handle 89 against the spring force exerted by the spring 111, the connecting rod 23 can be rotated clockwise (FIG. 13). When the golf trolley is unfolded, the connection piece 82 rotates about the pivot pin 81 and with its curved end face 129 along a semi-circular lateral surface 131 which is provided on or formed on the support profile 15 . The handle 89 can then be released again at the latest when it is in the folded position. The locking bolt 91 , which is also under spring tension, then snaps into the bore 121 .

Two tubular guide sections 129 and 131 are formed on the handle 89 and form-fittingly engage around the handlebar 23, with one of the two

Guide sections, in the present exemplary embodiment the guide section 131, is connected to the cable pull 87 (Fig. 119. The connection between the cable pull 87 and the guide section is via a pin 133 which passes through two elongated holes 135 aligned in the longitudinal direction of the handlebar. The length of the elongated holes 135 limits the stroke of handle 89.

A bracket 136 is articulated to the rear end of the steering rod 23 and can be adjusted about an axis of rotation 137 and preferably fixed in any desired position. The golfer thus has the option of adjusting the bracket 136 to the height which corresponds to his size and is most comfortable for him. According to an advantageous embodiment of the invention, the handle 89 is also connected to the locking mechanism for determining a pivoted position of the bracket 136 relative to the handlebar 57 in such a way that when the handle 89 is pulled back, the locking of the locking mechanism is also released and is preferably under spring preload standing bracket is pivoted into an end position in which the bracket runs approximately parallel to the handlebar (Fig. 1). As those skilled in many solutions are known, such as the adjustability of the bracket and the Locking mechanism can be realized, a more detailed description of the same is omitted.

A second embodiment of the golf bag 53 according to the invention is shown in greater detail in FIGS. The golf bag 53 comprises a base part 29a with the wheel housing 40 and a head part 30a. Bottom part 29a and top part 30a are connected to one another by means of several rods 141 and thus form a framework for the golf bag 53. Since the bottom part 29a is smaller in area than the top part 30a, the rods diverge slightly from bottom to top relative to one another.

The golf bag frame can be enclosed with a cover 51 made of a textile material and thus form a container for holding the golf clubs and other utensils that are required 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 there is no need for bars 141.

About halfway up are the two rear bars 141, which respectively the position of the rear wall. define the bottom of the golf bag, connected to each other by means of a clip 143. Seen from above, this clip 143 has an approximately circular indentation 145 which serves to accommodate the support profile 15 when the golf bag/golf trolley unit is in the folded state. As a result, the golf bag/golf trolley unit can be built very compactly. It is conceivable to provide a preferably dimensionally stable channel made of plastic adjoining the wheel housing 40, which channel extends from the wheel housing 40 to the head part 30 and serves to at least partially accommodate the support profile 15. However, this is not mandatory. As a rule, it is sufficient if the head part has a recess for accommodating the support profile, in order to generate a very compact golf bag/golf trolley unit.

The wheel housing 40 is preferably integral with the floor part 29 and has two opposing side walls 147a, 147b which are connected to one another by a connecting wall 149 on the golf bag compartment side. Lateral ears or webs 151a, 151b with U-shaped recesses 153a, 153b are integrally formed approximately halfway up the side walls 147a, 147b. The downwardly open recesses 153a, 153b serve to accommodate extensions 165 of the wheel axle 163 (FIG. 21). The bottom part 29a has a circumferential and upwardly protruding edge 155, which represents a lateral boundary for the golf club grips. Feet 157 are provided on the underside of the bottom part 29a, which form a standing surface for the golf bag.

On both sides of the wheel housing 40, the golf bag is narrower than the adjoining upper part of the bag (indentations 161), so that when the golf trolley is folded up, the rear wheels 27 are essentially accommodated in the periphery of the golf bag 53 (FIGS. 22 and 23). . The golf bag/golf trolley unit can thus be reduced essentially to the size of a conventional golf bag for transport purposes if the rear wheels can be parked in the lateral indentations 161 of the golf bag. As can be seen from FIGS. 23 to 25, the rear wheels 27 do not protrude laterally with respect to the container located above.

The front wheel 19 of the golf trolley has a wheel axle 163 which has extensions or protrusions 165 projecting axially outwards on both sides. The golf bag can be supported on these projections 165 when the downwardly oriented recesses 153a, 153b of the webs 151a, 151b are hooked onto the extensions 165 and are then held in a form-fitting manner (FIG. 29).

Above the wheel housing, the golf bag 53 can have side parts 167 made of a somewhat stronger, in particular dimensionally stable material, which protrude so far backwards that the golf trolley is accommodated within the periphery of the side parts 165 when viewed from the side. Together with the headboard 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 support surface of the golf bag).

Figures 28 and 29 show a third embodiment of a golf trolley, which is characterized by simplicity, compactness and lightness. The handlebar 23 is articulated on the support profile 15 via an angled connecting piece 171 in such a way that the axis of rotation 79 running perpendicularly to the longitudinal center plane of the golf trolley is at a distance from the support profile 15 . This has the advantage that the handlebar 191 in the folded state of the golf trolley is essentially parallel to the Support profile 15 can run. Specifically, the connecting piece 171 protrudes at an angle of between approximately 40 and 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 be pivoted about the pivot axis 69.

The rear of the head portion 30a has a U-shaped recess 172 as viewed from above, the legs 174 of which project upwards at an angle of between approximately 40 and 60 degrees. The second end of the support profile 15, on which the connecting piece 171 is arranged, is accommodated in the recess 172 when the golf bag 53 and golf trolley are combined. U-shaped recesses 181 can be provided in the legs 174 (Fig. 22), with which the head part 30a can be fastened to the golf trolley in a form-fitting manner if, for example, pins projecting laterally outwards 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 hung on the golf trolley, the pins projecting laterally in opposite directions from the connecting piece are accommodated in the recesses 174 .

Additional connecting means, e.g. straps, a snap connection or the like, can also be provided for the detachable connection of golf trolley and golf bag, so that the golf bag/golf trolley unit can be carried with one hand.

The parallelogram levers 60a, 60b are arranged on the support profile 15 via a holder 173 in such a way that their axis of rotation 63 runs at a lateral distance from the support profile 15. In addition, the axis of rotation 63 is located 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 one another when viewed in the folded state and in the direction of travel. This allows the golf trolley to stand upright without a golf bag, as the wheels form a three-point support.

The parallelogram levers 60a, 60b extend in the folded state preferably parallel and at a short distance from the support profile 15 and in the spread state at an angle of between 30 and 60 degrees to the vertical longitudinal center plane of the golf trolley. The front wheel 19 is arranged on a wheel fork 177 on the supporting section 15, the fork legs 179 of which are coaxial with the supporting section 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 arranged 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 support profile 15 designed as a tube and two lateral connecting bores 186 for receiving the ends of the fork legs 179. Both fork head 183, bracket 173 and connecting piece 171 can be attached to the support profile 15. These components can be fixed to the tube of the support profile 15 in a material or non-positive manner by means of an adhesive, welding, screws or rivets.

30 shows the individual parts of the golf trolley in an exploded view. From this it can be seen that the golf trolley can be assembled from just a few individual parts. In particular, the fork head 183, the holder 173 and the articulated holder 171 can be plugged onto the support profile tube 15. These parts 171, 173 and 185 can be attached by means of screws, bolts or an adhesive. In the case of the joint holder 171, this is clamped with clamping screws 188, in the case of the holder 173 with clamping screws 189 on the support profile tube 15. The fork head 185, on the other hand, is preferably connected to the support profile tube 15 with an adhesive, although other forms of attachment are also conceivable.

FIG. 31 shows the golf bag/golf trolley unit from the side. It can be seen that the supporting profile 15 and the handlebar 23 are accommodated within the periphery of the golf bag 53 .

The other FIGS. 31 to 35 show an advantageous embodiment of a rotary joint 189 for the articulated connection of a handle bar 191 to the chassis in more detail. The articulated bracket 171 has a tube-clamp-like connection piece 193 which encompasses the support profile tube 15 and can be screwed tight with the clamping screws 187 . Two cheeks 195a, 195b arranged at a distance from one another protrude from the connecting piece 193 at an angle of preferably approximately 45 degrees. A rotary 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 up, the handle bar 191 can extend essentially parallel to the support profile 15 .

Pivot 189 includes a rotary knob 199 and a mechanism associated with rotary knob 199 for locking the pivot in a once engaged position. The handle bar 191 , which can be pivoted about the pivot point 69 , is arranged on the rotary joint 189 .

The pivot 189 has an axis 201 which is bolted 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 to the opposite cheek 195b and has a socket 203b which extends through an opening 205b in the cheek 195b and has an external thread 207b. The external threads 207a, 207b of the sockets 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.

The rotary knob 199 is placed on the connecting piece 207b. This is connected via a coupling shaft 213 and a threaded pipe 215 firmly connected to the latter to a clamping nut 217, which can be moved back and forth by turning the rotary knob 199. The clamping nut 217 is coupled by means of the cylinder pins 219 to an axially movable coupling ring 221 (axis 223). A first toothed disk 225 is arranged on the coupling ring 211 in a rotationally fixed manner. The first toothed disk 225 can interact with a second identical toothed disk 227, which is arranged in a rotationally fixed manner via the cylindrical pins 229 on a rotatable joint body 231, on which in turn the handle bar 191 is arranged.

The locking mechanism works as follows:

The handle bar 191 is loosened or tightened by means of the turning knob 199 . To do this, the rotary knob 199 is turned approx. 1.5 counterclockwise for loosening and then the same number of turns clockwise for tightening. The torque, which arises when rotating the knob 199 is a Cylindrical pin 233 transferred to the coupling shaft 213 and the threaded tube 215, which are connected to each other via a dowel pin 235.

The clamping nut 217 is displaced in the axial direction 223 via the thread of the threaded tube 215 . If the rotary knob 199 is turned counterclockwise to loosen, the clamping nut 217 is displaced to the left in FIG. 35 and to the right in the other case.

The coupling ring 221 is connected to the clamping nut 217 by means of the two cylinder pins 219 . The first toothed disk 225 is in turn screwed onto the coupling ring 221 .

For its part, the coupling ring 221 is guided with the axis 201 via cylindrical pins (not visible in FIG.

The axis 201 is with the cheek 195a, which respectively fixed to the chassis. Headboard is connected, screwed and thus an upcoming torque can be derived from the chassis.

In the tightened or closed state, the toothed disc 225 and the toothed disc 227 are positively connected to one another. If a torque is applied to the articulated body 231 via the handle bar 191, this is transmitted to the toothed disc 227 via the cylinder pins 229. As described in the previous section, the torque can be derived as a result of the form fit between the two toothed discs 225, 227.

If mm the knob is turned counterclockwise, the parts 217, 221, 219 and 225 described above move in the axial direction to the left. After 1.5 revolutions, the toothing of the two toothed disks 225, 227 is no longer in mesh with one another and the articulated body 231, on which the handle bar 191 is mounted, can rotate freely.

The golf trolley and the golf bag are used as follows: When used for the first time, the starting position is the folded golf trolley 11 and the separate golf bag 53. The golf trolley is first set up vertically, the handlebar 23 lock is released and then the handlebar from the support profile swung away. At the same time, the rear wheels are swiveled into the spread position. The handlebar 23 is adjusted to a height adapted to the size of the golfer and then locked (Figs. 28 and 29). Thereafter, the golf bag is 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 in place on it in a form-fitting and/or non-positive manner.

After setting up the golf trolley for the first time and fixing the golf bag to it, they can remain together permanently for further use (playing, transport in the car and storage), firstly because the golf bag with golf trolley is only slightly larger than a conventional golf bag, and secondly because the golf trolleys made of lightweight materials have little weight. This means that the golf bag and golf trolley now form a golf bag-golf trolley unit, but with the advantage over the integrated golf bag trolley mentioned at the beginning that the golf trolley and golf bag can be separated again at any time with a flick of the wrist, for example if the golf trolley is to be used by different people . It is also conceivable that different manufacturers produce golf bags for the golf trolley according to the invention according to the proposed inventive concept.

To fold the golf bag/golf trolley unit, the golfer first releases the handlebar lock, pivots it towards the support profile and then locks it again. The golf bag and golf trolley unit is then in a vertical position. If the golf bag/golf trolley unit is tilted, it can be pushed or pulled on the way from the playing field to the parking lot to save space. In contrast to the golf bag trolleys mentioned above, the golf bag/golf trolley unit does not have to be carried since the wheels of the golf trolley still protrude from the periphery of the golf bag in the folded position. To load into the trunk of a car, the golf bag/golf trolley unit is laid down (handlebar down), the whole unit is lifted and placed in the trunk. A carrying handle (not shown in the figures) can be provided approximately in the middle of the golf bag for carrying the unit. In the more complex embodiment of a golf trolley with a locking mechanism according to FIGS. 11 to 14, the golfer first unlocks the handlebar 23 to erect the golf trolley and then swivels it upwards until the snap mechanism automatically locks when the end position is reached and fixes the actuating rod in the assumed position . Simultaneously with the pivoting of the handlebar 23, the golf bag/golf trolley unit is placed in an inclined position and supported on the rear wheels. The handlebar 23 can also be unlocked by the movable handle 89 . Then the bracket, if it is height-adjustable, can still be adjusted to the appropriate height.

To fold the golf bag/golf trolley unit, the golfer first grasps the handle 89, pulls it back and thus releases the latching of the operating rod 23. The handlebar 23 is then pivoted downwards and the golf bag/golf trolley unit is brought into the upright position at the same time. In this position, the handlebar can be locked again, either by a separate snap mechanism or by means of the spring-loaded bolt 91. If 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 stowed in the trunk of a car.

The invention relates to a golf bag for holding a plurality of golf clubs, which is characterized in that a wheel housing for the front wheel of a three-wheel golf trolley is formed in the bottom part of the golf bag. The golf bag is designed to be attached to a three wheel golf trolley. The golf trolley has a front wheel with an axle having outwardly projecting axial extensions on opposite sides of the front wheel which form a support for the golf bag. One end of the golf bag can be secured by means of a form fit on the front wheel and the other end by means of a form fit and/or force fit on the carrying profile of the golf trolley.

The terms “front wheel”, “rear wheels” used in the description are not to be understood as limiting, because the golf trolley according to the invention can be pushed (Normal case) or also be pulled. The individual features can also be implemented in different combinations on a golf trolley.
