GOLF BAG AND GOLF CART ASSEMBLY
A cart assembly for coupling to a golf bag, the cart assembly being moveable between a collapsed state and a deployed state and a coupling arrangement for coupling a golf bag to cart assembly, the coupling arrangement including one or more supporting collars corresponding in shape to a portion of the golf bag, the supporting collar attached to a coupling member wherein the coupling member is adapted to couple to a corresponding coupling portion located on the cart assembly.
The present invention relates to a golf bag assembly and/or a golf cart assembly. In particular the present invention relates to a golf bag assembly and golf cart assembly that are able to cooperate to provide a golf bag cart arrangement that is compact.
BACKGROUNDGolf carts, also known as golf buggies or golf trolleys, are popular with the majority of golfers that do not wish to carry their golf bags containing their golf clubs whilst playing a round of golf or who do not wish to use a motorised golf buggy. A golf bag may be simply strapped to a cart, which typically has two or more wheels, and the golfer proceeds to pull the cart along in front or behind them making transporting the bag of golf clubs around a golf course significantly easier than directly carrying them the distance which can involve travelling for around 5 to 9 kms.
There are many styles of golf cart that are in common usage today, many of which collapse to a certain extent so as to reduce their size for transportation to and from the golf course. However, the majority of golf carts do no collapse to a sufficient extent to allow multiple golf bags and carts to be stowed in a typically sized boot of a vehicle. Nor do such golf carts reduce sufficiently in size to enable them to be stowed as luggage on a plane with relative ease.
Numerous attempts have been made to reduce the size of golf carts to make them more suitable for travel. One attempt included directly coupling wheels onto the sides of a golf bag which significantly reduced the overall size of the combined cart and bag arrangement. However, such an arrangement does not provide sufficient width between the wheels when pulling the golf bag to provide a stable platform where such a golf bag often topples over when negotiating undulating terrain as is often found on a golf course.
Accordingly, there is a need for a golf cart assembly or a golf bag and cart assembly that is sufficiently compact for travelling requirements and which still provides sufficient stability when in use on a golf course.
SUMMARYAccording to one aspect the present invention provides a cart assembly for coupling to a golf bag, the cart assembly being moveable between a collapsed state and a deployed state, the cart assembly including:
-
- a main body portion including one or more coupling elements for coupling the
- main body portion to a golf bag;
- a handle member including a handle at one end and a connection point at the other end for coupling the handle member to the main body portion wherein the handle member is able to pivot about the connection point which moves the cart assembly from the collapsed state, where the handle member is located adjacent the main body portion, and the deployed state, where the handle member extends away from the main body portion; and,
- two wheel supporting members each including a wheel coupling point at one end for cooperating with a wheel, and a connecting arrangement at the other end for coupling the wheel supporting members to the main body portion, wherein each wheel supporting member is able to pivot about the connecting arrangement coupled to the main body portion which moves the cart assembly from the collapsed state, when each wheel support member is located adjacent to the main body portion, and the deployed state, where each wheel support member extends away from the main body portion.
In one form the main body portion is elongate and is located along the length of a side of the golf bag when coupled thereto.
In one form the main body portion includes at least two coupling elements for coupling the main body portion to a golf bag.
In one form the connecting arrangements of the two wheel supporting members are coupled to the main body portion at a point that is located in a middle region of the golf bag when coupled thereto. In one form the connecting arrangements of the two supporting members are coupled to the main body portion adjacent one another.
In one form the two wheel supporting members extend in a substantially perpendicular manner relative to the main body portion when in the deployed state. In one form the angle between the two wheel supporting members extending out from the connecting arrangements when in the deployed state is less than about 180 degrees and greater than about 30 degrees. In a further form the angle between the two wheel supporting members extending out from the connecting arrangement when in the deployed state is between about 70 degree and about 95 degrees. In yet a further form the angle between the two wheel supporting members extending out from the connecting arrangement when in the deployed state is about 85 degrees.
In one form the cart assembly further includes a lateral restriction member coupled between the two wheel supporting members wherein the lateral restriction member inhibits the two wheel supporting members from moving away from each other when in the deployed state. In one form the lateral restriction member is flexible thereby permitting the wheel supporting members to move towards each other when moving into the collapsed state.
In one form the cart assembly further includes two support rails wherein one support rail is coupled to the handle portion and one of the wheel supporting members and the other support rail is coupled to the handle portion and the other wheel supporting member. In one form movement of the handle portion from the collapsed state to the deployed state provides the support rails move the wheel supporting members from the collapsed state to the deployed state. In one form the support rails are coupled to the handle member at a point that is a distance along the length of the handle member from the connection point. In one form the distance along the length of the handle member from the connection point is less than 20 cm. In one form the two support rails are coupled to the handle portion via a ball joint, wherein the ball joint allows the support rail to pivot in all planes relative to the handle member whilst the handle member is moving between the collapsed state and the deployed state.
In one form the length of the handle member is adjustable.
In one form the cart assembly further includes a third wheel support member coupled to the lower end of the main body portion wherein the third wheel support member provides a wheel coupling point for locating a third wheel at a base region below the golf bag when coupled thereto. In one form the third wheel support member is able to move relative to the main body portion between a deployed position, wherein the third wheel support member extends beyond the main body portion, and a retracted position, wherein the third wheel support member is adjacent the main body portion.
In one form the cart assembly further includes a motor assembly coupled to at least the wheels located at the end of the wheel support members wherein the motor assembly is capable of rotating the wheels. In one form the motor assembly is operated via a controller wherein the controller is located on the handle portion of the cart assembly, or the motor assembly is operated via remote control.
In one form the wheel coupling points include an axel portion extending therefrom, the axel portion being capable of cooperating with and being retained within a corresponding orifice located at the hub of a wheel.
In one form the cart assembly is directly coupled to the golf bag. In one form the main body portion of the cart assembly includes one or more coupling elements which correspond to one ore more coupling arrangements located on the golf bag. In an alternative form the cart assembly is integral with the construction of the golf bag.
According to another aspect the present invention provides a coupling arrangement for coupling a golf bag to an item, the coupling arrangement including one ore more supporting collars corresponding in shape to a portion of the golf bag, the supporting collar attached to a coupling member wherein the coupling member is adapted to couple to a corresponding coupling portion located on the item.
In one form the item is a golf cart assembly. In another form the item is a cart assembly as herein described.
In one form the portion of the golf bag is located in the neck region and/or the base region of the golf bag. In another form the supporting collar is located within the construction of the golf bag.
In one form the coupling member includes a female receiving portion with an internal thread which corresponds to a thread around a male coupling member located on the item.
In order to enable a clearer understanding of the present invention, one or more preferred embodiments will hereinafter be described with reference to the attached drawings, and in those drawings:
In certain embodiments, the present invention provides a cart assembly for coupling or permanently attaching to a golf bag wherein the cart assembly is able to move between a collapsed state and a deployed state. In the deployed state, the cart is in a position to enable a user to push or drag the cart along the ground to facilitate carrying the attached golf bag over terrain such as a golf course. In the collapsed state, the cart assembly, even when attached to the golf bag, is in a sufficiently compact state to easily enable the bag and cart to be carried or transported together. This provides that the golf bag and cart assembly may be carried as one for transporting to and from the golf course, or as luggage stowed on a plane if desired without the need for decoupling the cart assembly from the golf bag.
In addition, the cart assembly of the present invention may be used in conjunction with existing golf bags that are already on the market. In one form, existing golf bags may be altered to include a coupling arrangement as hereinbefore described with the associated supporting collar being incorporated within the golf bag construction or alternatively located on the outside surface of the golf bag.
In accordance with various embodiments, the cart assembly according to the present invention is very easy to assemble and may be operated by one hand by simply releasing the handle member from the collapsed state by a thumb operated catch, and raising the handle member into the deployed state. Similarly, the cart assembly is easy to move again into the collapsed state, by releasing a retaining catch and dropping the handle member into the collapsed state.
In one embodiment, the wheels are separate from the cart assembly and may be fitted once the cart assembly is in the deployed state. This provides that the wheel size may still be of sufficient diameter so as not to compromise the ride quality of the cart assembly when in the deployed state.
Referring now to
The cart assembly 10 includes an elongate main body portion 15 which is coupled to and is positioned to run along the length of a golf bag 11. Two turnbuckles 39, 42, are located at the neck and base portions of the golf bag 11 respectively. Each turnbuckle 39, 42 including a female receiving portion with a thread on the interior of the receiving portion which corresponds to a thread located on a male coupling portion 37, 41 located at the top end and bottom end of the main body portion 15 of the cart assembly 10. The male coupling portions 37, 41 are inserted and secured into the receiving portions of the turnbuckles 39, 42 thereby attaching the main body portion 15 of the cart assembly 15 to the golf bag 11.
The cart assembly 10 includes a handle member 17 with a handle 18 at one end which extends away from the main body portion 15 when in the deployed state (shown in
The main body portion 15 also includes a secondary handle member 21 which is located at the top end of the main body portion 13 spaced away from the general line of the main body portion in the opposite direction to the golf bag 11. The secondary handle member 21 allows a person to carry the golf bag 11 and cart assembly 10 in one hand when the cart assembly is in the collapsed state.
In addition, connection point 19 is also located on this spaced away region of the secondary handle member 21 which provides that when the handle member 17 is in the deployed state, the handle member 17 is also spaced away from the golf bag itself (as shown in
Coupled mid-way down the elongate main body portion 15 at approximately a mid-point along the length of the golf bag 11, two wheel support members 20 are coupled to the main body portion 15 by means of two connecting arrangements 25 (one of which is hidden in
In the deployed state shown in
The wheels 47 may be separated from the axel portions 28 such that the wheel supporting members 20 may be moved into the collapsed state as shown in
In order to restrict the wheel supporting members 20 moving in a lateral direction away from one another once in the deployed state shown in
In order to provide further support to the wheel supporting members 20 when in the deployed state, two support rails 22 are connected from the wheel supporting members 20 at a point 43 adjacent the wheel coupling point or axel portions 28. The other ends of the support rails 22 are coupled to the handle member 17. The support rails 22 are coupled to the handle member 17 at connection point 31 which in this embodiment is in the form of a ball joint fixed to the bottom end of the handle member adjacent the connection point 19 connecting the handle member 17 to the main body portion 15. The connection point 31 is approximately 10 to 20 cm along the length of the handle member 17 from the connection point 19.
The support rails 22 provide additional support to the structure of the cart assembly 10 when in the deployed state, and also provide that movement of the handle member 17 from the collapsed state shown in
In order to provide for the various directions which the support rails 22 move from in relation to the handle member 17 when moving from the collapsed state to the deployed state, the support rails 22 are connected via a ball joint which is fixed relative to the handle member 17 and which allows the support rails 22 to move in three possible translations (x, y, z) during the range of motion from the collapsed state to the deployed state. The connection point 43 at the other end of the support rails 22 connecting the support rails 22 to the wheel supporting members 20 enables the ends of the support rails 22 to rotate with respect to the wheel supporting member 20 to allow for the motion of the wheel supporting members 20 as they move from the collapsed to the deployed state. The ends of the support rails 22 are angled and extend in a perpendicular manner away from the wheel supporting members 20 for a short distance before an angle of about 80 to 90 degrees which leads into the elongate body of the support rails 22.

From the collapsed state depicted in
Turning to
Once the deployed state has been attained, the two wheels may be fitted over the axel portions 28 of the wheel supporting members 20 and the golf bag cart assembly is ready for operation. As the axel portions 28 of the wheels are located on the cart assembly 10, the wheels may be easily clipped together when the cart assembly is in the collapsed state and placed within a compartment on the golf bag or alternatively attached to the golf bag via a clip or like means. The axel portions 28 are covered by the handle 18 when the cart assembly is in the collapsed state shown in
Turning to
The supporting collar 53, 54 may be constructed of any suitable material such as plastic or metal that has sufficient structural integrity to provide support. A locating plate is connected to the supporting collar 53, 54 and/or to the golf bag 11 via a rivet which includes the female receiving portion 56 with a screw thread around the interior of the receiving portion for cooperating with a corresponding male connecting portion included on a cart assembly 10 as depicted in
The supporting collar 53 composed with very deliberate grooves to produce a shape that not only follows the curve of the bag but also delivers significant strength for its weight.
However, the coupling may be equally the reverse wherein the turnbuckles 39, 42 include male coupling elements which correspond with female receiving portions located on the cart assembly 10.
The base bracket 60 also includes bracket support flanges 62 which abut the base of the golf bag when the golf bag is strapped to the cart assembly 10. The bracket support flanges 62 carry the weight of the golf bag and ensure the golf bag does not slip down through the tethers 70 and 72 whilst the bag is being carried by the cart assembly 10. The bracket support flanges 62 can be attached to the brackets 60 via pin arrangement 61 which allows the bracket support flanges to pivot relative to the bracket 60 to accommodate different sized bases of golf bags.
The embodiment shown in
A further embodiment of the present application is shown in
A mechanism for moving the third wheel support member 82 from the retracted and deployed states consists of an actuator line 87 attached to the third wheel support member 82 which may be pushed or pulled via movement of an actuator 90 which is connected to the actuator line 87 via actuator line fastener 91. In this way, the cart assembly 10 may be moved from the collapsed state to the deployed state as described above, and once in the deployed state, the actuator 90 may be moved to operate the actuator line which in turn moves the third wheel support member 82 from the retracted state to the deployed state. The third wheel 80 may then be placed onto the third wheel axle 81 in order to provide a cart assembly 10 in a three wheel arrangement.
Typically the third wheel 80 may be smaller than the back wheels 47. In addition, as a three wheel arrangement is often pushed rather than pulled, the three wheel option can include an adjustable handle member 18 which provides that the height of the handle 18 can be adjusted relative to the handle portion 17. The handle 18 is also sized to accommodate two hands which facilitates a more chiropractically friendly symmetrical body form when in use.
The use of the third wheel 80 also provides that a braking mechanism for a back wheel can be included in the construction with the cart assembly such that the three wheel embodiment may be placed on a slope without the cart moving without the control of the person using the cart assembly. In a further embodiment, the three wheel arrangement of the cart assembly 10 may also be fitted with a motor which drives at least the two back wheels 47 of the assembly. In one form, electric motors and batteries would sit entirely within the hub of each of the back wheels 47. By having the weight of the electric motors and batteries sitting within the wheels there, is no need to reinforce the cart assembly frame to cater for the additional weight.
The control for such an electric motor would sit either in the handle 18 of the assembly 10 or alternatively be remote controlled. The controls could also incorporate a display screen and can be removed for security and/or charging when not in use.
The construction of the wheel 47 provides for an easy mechanism for someone to merely push onto the release button 109 to disengage the wheel from the axle portion 28 of the cart assembly 10 which provides that moving the cart assembly 10 can be quickly moved to the collapsed state and stowed for storage. The wheel assembly 47 also provides that it is quick to move the cart assembly to the deployed state and attach the wheels 47 as they essentially click onto the axel portions 28 are then retained until the release button 109 is again pushed.
It is also envisaged that whilst being smaller the third wheel 80 shown in
