Description

Collapsible golf cart

The invention relates to a collapsible golf cart for transporting a golf equipment comprising a support frame, an arranged on the support frame receptacle for the golf equipment and at least two articulated to the support frame wheels.

Golfcars, so-called Caddies, of the type mentioned are known and serve to carry heavy golf equipment during a game of golf. The equipment, including a variety of golf clubs, which can weigh up to 25 kg in total, is housed in a golf bag which is attached to the golf cart. Such golf carts are pulled on a golf course over natural ground, especially grass, sand, gravel, etc., and should also be able to roll up or down a slope or embankment, which is why a golf cart has a high degree of ruggedness, off-road capability and Must have smooth running. In particular, it should be mentioned here that the wheels under the load of heavy golf equipment not in a soft ground such. B. soft grass or sand sink or the golf cart not on bumps in the ground such. B. protruding stones, roots or mounds may remain hanging. In addition, the golf cart should be stable, even if the ground is sloping or wavy. Overall, a golf cart should be tough, lightweight, off-road, and easy to pull.

To be able to transport the golf cart simply and space-saving, in particular to be able to transport it in a trunk of a passenger car, the golf cart is formed collapsible. For this purpose, the golf bag is usually removed from the golf cart, and the chassis struts belonging to the chassis, to which the wheels are attached, are folded toward the body of the golf cart, so that the chassis struts fit snugly thereon, where be significantly reduced by the cross-sectional dimensions of the overall structure of the folded golf cart. However, the dimensions thus reduced are often not sufficiently small to be able to transport the golf cart comfortably even with a small car such as a sports car or a convertible. Sports cars as well as convertibles usually only have a limited trunk volume, which is difficult to transport the known golf cart or, if there are more pieces of luggage in the trunk, does not allow. This is particularly the case when in addition to the folded golf cart and the golf bag should find space in the trunk.

A variety of golf carts have been designed with the aim of providing heavy golf equipment across a variety of natural golf course grounds such as golf courses. B. grass, sand or gravel, where they should be transported at the same time with a car. For transporting the golf cart in a trunk of a car various folding mechanisms were devised in which the wheelbase or the length of the golf cart was reduced by means of a folding mechanism or in which the wheels were removed from their axles. US Pat. No. 6,302,430, for example, shows a foldable golf cart, in which the wheels fastened to support rods are folded with the support rods inwardly toward the support frame of the golf cart. DE 103 42 923 discloses a golf cart, which is folded into a compact and handy unit by the wheels are dismantled with their suspension struts. Despite these extensive efforts to design a rugged yet compact golf cart, the dimensions of the folded or folded golf carts are not sufficiently small to allow convenient transportation of the golf carts.

The invention is therefore based on the object to provide a golf cart that is off-road, robust, lightweight and easy to handle and particularly compact folds. Moreover, the invention has for its object to provide a particularly convenient, safe and practical transport aid for a golf cart.

This object is achieved according to the invention as indicated in the independent claims. Further advantageous embodiments and developments, which can be applied individually or combined with each other, are the subject of the respective dependent claims. In this case, further developments of the subject matter of the one independent claim with the further development of the subject matter of the independent claim can be combined with one another as desired.

According to the invention, the collapsible golf cart for transporting a golf equipment comprises a support frame, arranged on the support frame mount for the golf equipment and at least two articulated to the support frame wheels, for folding the golf cart, the wheels from a first position for transporting the golf equipment in a to Collapsing the golf cart second position are pivotable, wherein the wheels are arranged substantially coaxially in the first position and in the second position are substantially coplanar in a plane.

Coplanar here means that the roles lie in a common plane, so not skewed to each other. Due to the coplanar arrangement of the two wheels in the folded position, the golf cart achieves a high level of compactness, since the construction heights of the wheel arrangements, which are determined in particular by the lengths of the wheel axles, do not add together. It is realized a particularly flat folding position. Due to the coplanar arrangement of the wheels, the volume of a gap between the Wheels, which is comparatively large in the folded, known golf cart with coaxial wheels arrangement, significantly reduced, so that a total of space gain is achieved.

With the combined golf cart, a golfing equipment can be easily transported even with a weight of over 20 kg. It is expediently designed for at least 30 kg, in particular for at least 40 kg, which requires a corresponding adaptation of the support frame, the wheels and the bearings of the wheels or the joints for the wheels. The bearings of the wheels are conveniently high quality ball bearings or roller bearings to ensure a high degree of stability. The golf equipment is attached by means of the recording on the support frame. For this purpose, the receptacle may have a plurality of individual receiving surfaces, but may also be formed by a one-piece or two-part large-area receiving surface. Advantageously, the golf cart is pulled.

In the first position for transporting the golf equipment over a golf course, the wheels of the golf cart are substantially coaxially arranged, i. the respective axes of the wheels are arranged in alignment with each other. The golf cart permits the transport of heavy equipment on a variety of surfaces, especially on natural ground such. As grass, sand or gravel, without being stuck to protruding from the ground objects such as stones, roots or Bodenhubbein.

In one embodiment of the invention, the golf cart on the transport of golf equipment on a ground clearance of 6 cm to 30 cm, in particular from 10 cm to 15 cm. With ground clearance is meant the distance that the carrier frame of the golf cart during the transport of golf equipment to a has flat surface when the golf cart rests with its wheels on the surface. The ground clearance indicates how high an object protruding from the base can protrude without the golf cart touching or hanging on it. With a ground clearance of 10 cm to 15 cm, the golf cart can still be pulled or pushed well, even if hand-sized stones, roots or piles of earth protrude into the air.

In a development of the invention, the wheels have a diameter of 25 cm to 40 cm, preferably a diameter of 28 cm to 35 cm. Diameters of at least 25 cm, in particular of at least 28 cm, are advantageous in order to allow easy rolling of the golf cart on rough ground. In particular, this facilitates the pulling or pushing of the golf cart, whereby the handling of the golf cart is simplified. Fist big stones can be rolled over by the wheels without much effort. A diameter of less than 40 cm, in particular less than 35 cm, allows the achievement of a special compactness when folding the golf cart.

In a further embodiment of the invention, the wheels in the first position have a wheel spacing of 50 cm to 80 cm, in particular a wheelbase of

50 cm to 65 cm, preferably a wheelbase of 50 cm to 60 cm, on.

By a wheel distance of more than 50 cm, in particular more than 55 cm, the golf cart remains stable in difficult terrain, ie when the ground is inclined or Hubbel has. Tipping over to the side is prevented. By a wheel distance of less than 80 cm, in particular less than 60 cm, the golf cart remains easy maneuverable. In a specific embodiment of the invention, the wheels have a width of 4 cm to 10 cm, in particular a width of 5 cm to 7 cm. By a width of more than 4 cm, in particular more than 5 cm, prevents the wheels on soft ground such. B. grass sinking into the ground excessively strong. An excessively heavy rolling of the golf cart is avoided. Due to the large bearing surface of the wheels, especially at widths of more than 5 cm, it is ensured that the golf cart can be easily pushed or pulled even with heavy golf equipment. Widths of less than 10 cm, in particular less than 7 cm, are advantageous in order to obtain the smallest possible height of the golf cart in the folded position. Due to the width of at least 4 cm, preferably at least 5 cm, the golf cart does not sink into a soft ground, which increases its off-road capability. In addition, the width of the wheels damage to the ground, for example, a fine lawn is reduced, making the golf cart easier to travel.

Advantageously, the wheels have pneumatic tires and / or a profile. A pneumatic tire achieves a high level of ride comfort. The profile prevents slipping of the golf cart, for example on slopes on wet grass.

Advantageously, the receptacle has a support surface and a foot surface projecting from the support surface at an angle of 80 degrees to 100 degrees. The golf equipment, in particular the golf bag, is held against slipping by means of the support surface under the foot surface projecting substantially at right angles thereto. Both the support surface and the foot surface can be formed by a profiled tube linkage, a net suspended from the chassis or by individual receiving surfaces. In a particular embodiment of the invention, the wheels are locked in their first position by means of the foot surface. For this purpose, advantageously, the foot surface is pivotally connected to the support surface, so that the foot surface can be pivoted relative to the support surface to be arranged substantially parallel to each other in the folded position of the golf cart and to be substantially perpendicular to each other in the unfolded position of the golf cart. With the help of the foot surface, the wheels are locked in the first position, so that they are arranged substantially coaxially with each other and remain held in the lane. Conveniently, the wheels can also be individually locked in relation to the chassis by means of separate or cooperating locking devices.

In a special embodiment of the invention, the receptacle has arched receiving surfaces, in particular receiving surfaces for a cylindrical golf bag. In this case, the golf bag in cross section may also be oval, square or D-shaped. Advantageously, the Aufhahmeflächen, in particular the curved Aufhahmeflächen, equipped with straps to secure the golf equipment, especially the golf bag to the chassis safely. The straps can also be mounted directly on the chassis.

Advantageously, at least two Aufhahmeflächen along a longitudinal direction of the support frame are arranged one behind the other. The longitudinal direction of the support frame corresponds to the longitudinal direction of the golf equipment, which essentially corresponds in most cases to the direction of the golf clubs in the golf bag. The arrangement of the accommodating surfaces along the longitudinal direction keeps the golf equipment in a simple manner with only a few means, whereby a weight advantage is achieved. In a particular embodiment of the invention, the support frame is fork-shaped, wherein in each case a wheel is attached to a fork arm. By the fork shape of the support frame, a high degree of rigidity of the support frame is achieved, at the same time the weight of the golf cart is reduced. Here, the wheels are each attached to a fork arm. At the fork arms opposite end, the fork foot, a handle for pulling or pushing the golf cart is advantageously attached. Due to the fork shape of the carrier a special off-road capability of the golf cart is achieved, even if one of the two wheels on a bump on the ground such. B. rolls over a stone.

In a further embodiment of the invention, the support frame has an upper part, in particular a longitudinal bar, and a lower part, in particular a fork, wherein the upper part can be folded or displaced relative to the lower part, in particular telescopically displaced. Due to the division of the support frame or the subdivision into even more parts of the golf cart can be folded very compact. Here, the upper part may be hinged to the lower part, so that the upper part can be folded onto the lower part. It is advantageous to connect the upper part to the lower part by means of a sliding mechanism, so that the upper part can be pulled out of the lower part. Here offer telescopic sliding systems. Due to the multi-division of the support frame, the length of the golf cart, which is predetermined in the unfolded state by the length of the golf equipment, for the folded state of the golf cart can be significantly reduced. The golf cart thus has a length of less than 70 cm, in particular less than 60 cm, preferably less than 50 cm, particularly preferably less than 40 cm in the folded state. Between the upper part and the lower part, a locking mechanism for the joint or the displacement mechanism is advantageously provided in order to allow a sufficient stability even with strong pulling or pushing the carriage. The upper part is special formed by a longitudinal rod, at the free end of a handle, in particular a one-hand grip is attached. The lower part can be formed from a substantially T-shaped structure, but in particular has a fork or a Y-shaped structure.

In a special embodiment of the invention, the upper part has a displacing part guided on the lower part, in particular a transverse yoke, wherein in particular the lower part has at least two longitudinal members on which the displacing part is designed to be longitudinally displaceable. By sliding along the displacement part on the two longitudinal members, a telescopic connection is realized between the upper part and the lower part, which ensures a particular degree of stability.

In a development of the invention, the upper part and / or the lower part has a clamping device and / or a releasable latching device for fixing the upper part relative to the lower part. A clamping device or a releasable latching device is advantageous in order to avoid a displacement, slipping or folding of the upper part relative to the lower part, even if the upper part or the lower part of a high mechanical stress is subjected, as for example in a heavy Golf equipment can occur in uneven terrain. The advantage of a releasable locking device is that the total length of the upper and lower part in the unfolded state of the golf cart can be adjusted depending on the length of the golf equipment or size of the person pulling the golf cart. By adjusting the size of the overall length of the upper and lower part of an individual adaptation of the golf cart to the needs of the golfer can be accomplished. In a further specific embodiment of the invention, a handle and / or a card holder, in particular a fold-out or displaceable handle and / or a fold-out or displaceable card holder, is arranged at a free end of the upper part. The handle is also advantageously suitable for use with only one hand. With the help of the card holder scorecards can be kept clear for the golfer. The handle or the card holder is designed to be foldable or displaceable, so that the golf cart also has a high degree of compactness in the folded state. For this purpose, the handle or the card holder is connected by a hinge or a corresponding sliding mechanism with the upper part. The joint or the displacement mechanism advantageously comprises a latching device for fixing the handle or the card holder relative to the upper part. For this purpose, it is expedient that with the aid of the locking device different positions of the handle or the card holder can be adjusted to achieve a special adaptation to the needs of the golfer. In particular, this can be adapted to the optimal position of the handle for the golfer.

It is advantageous if the support frame is made of carbon, a plastic, an aluminum alloy and / or a titanium alloy. Such materials allow a lightweight construction of the golf cart, which allows a particularly easy handling of the golf cart. Also advantageous are combinations of such materials. Carbon, aluminum alloys or titanium alloys allow for particularly rigid designs of the golf cart with low weight. For this purpose, the supporting parts, in particular the support frame are advantageously made of profile tube.

In a further embodiment of the invention, the support frame on a third wheel, preferably a pivotable wheel on. In particular, the third wheel is attached to a provided with caster and / or fall wheel fork. A third tes wheel is particularly advantageous for the sliding operation of the golf cart. In this case, the third wheel can be arranged in the sliding direction before as well as behind the support frame. However, it is preferred that the third wheel is the front wheel and the other two wheels form the rear wheels. The third wheel is advantageously attached to a wheel fork, which is pivotable and is advantageously provided with a caster and / or camber. This allows a special maneuverability of the golf cart.

In a special embodiment of the invention, the third wheel is attached to a foot surface.

Advantageously, the golf cart has a braking device, in particular a braking device with Bowden cable, for at least one of the wheels, in particular for two wheels. With the help of the braking device, the golf cart can be braked when the ground is sloping. For this purpose, there is advantageously a handbrake on the handle, with which the golf cart is held. The hand brake then acts via a Bowden cable with the braking device on the wheels or on the wheel. With the braking device, the golfer can effortlessly traverse sloping terrain with an incline of 10% to 30% incline without the golf cart overturning the slope too much pulls down.

In a further particular embodiment of the invention, a spring, in particular a gas spring, is arranged in an articulated manner between the parts which can be pivoted from one another into the unfolded state of the golf cart. The spring is preferably lockable and / or formed with a lock. With the help of the spring, a folding or unfolding of the golf cart is simplified. In particular, this can be a semi-automatic unfolding of the golf cart be effected, preferably the golf cart jumps from the folded state with a snap action in the unfolded state. For this purpose, the spring can be biased when folding the golf cart, so that it relaxes on pressing a triggering device during the construction of the golf cart. In this way, a particularly comfortable unfolding of the golf cart is made possible, which positively influences the handling of the golf cart.

With the help of the spring of the golf cart can be at least partially independently unfolded and / or collapsed.

In a further embodiment of the invention, the receptacle on the support frame in the first position defines a plane having a next distance of 10 cm to 50 cm, in particular 12 cm to 40 cm, preferably 15 cm to 30 cm, to the axis of rotation of the rollers , The next distance means the distance that a rotation axis of the rollers occupies in the first position from the plane defined by the receptacle on the support frame, the plane being substantially parallel to the longitudinal direction of the support frame and parallel to the axes of rotation of the rollers in the first position extends. Due to the distance of this plane from the axes of rotation can be a long golf equipment from 80 cm to 120 cm are placed on the recording without the golf cart is unstable. Due to the distance, the golf cart with the golf equipment can be tilted, whereby a high level of stability is achieved. In addition, with the distance between the plane and the axes of rotation, the ground clearance of the golf cart can be significantly increased.

In particular, the golf cart has a support leg or a support wheel for obliquely supporting the support frame relative to the vertical, in particular for supporting it at an angle of 10 degrees to 70 degrees relative to the vertical, preferably at an angle of 30 degrees to 60 degrees relative to the vertical, more preferably at an angle of 40 degrees to 55 degrees relative to the vertical. Even on sloping or undulating surfaces, the golf cart stays stable and does not fall over.

Advantageously, the wheels are pivotable from the first position in each case along a longitudinal direction of the support frame in the second position. By the pivoting of the wheels along the axis parallel to the longitudinal direction of the support frame, a coplanar arrangement of the wheels can be realized in the second position in a simple manner.
