Abstract

The sprung golf trolley gas a support frame (2) for the bag (1) and a chassis (3). There is a sprung suspension (4) between the support frame and chassis. The support frame can be formed integrally with the golf bag or the bag can be removable. The chassis can have a motor such as an electric motor to operate driven wheels. The suspension can use a gas strut.

Description

The The present invention relates to a golf trolley according to the preamble of claim 1.

At the Golf becomes the golf clubs in one for this provided bag, dam so-called golf bag, stored and transported. Due to the high weight of the bag with rackets, it is known this with a handcart, a so-called golf trolley, which can be pulled or pushed by the player.

there The bag can be detachable Connected to the golf trolley to separate bag and trolley to be able to transport. equally can Bag and trolley also in one piece be formed with each other. Preferably, the trolley also includes an autonomous drive, such as an electric motor with batteries as an energy supply to drive automatically by remote control or at least the golfer pulling or pushing the trolley to support.

Golf courses, up the trolleys explained above used include natural paths, golf turfs (so-called fairways) and more impassable terrain (so-called Rough), and are often cropped, wavy or otherwise uneven. When driving over such bumps like tree roots, holes, bigger stones or the like learns the golfer pulled, pushed or remotely controlled remote-controlled and independent moving trolley vertical impulses. These lead to rattling of the golf clubs in the bag, Scour the rackets to each other and to the bag and shaking the remaining contents of the golf bag, such as drinks, balls and like. This leads adversely to noise pollution, Wear and disorder in the golf bag.

task It is therefore an object of the present invention to provide a golf trolley put, the jerky shocks while reduced driving on the golf course.

The Invention creates a solution this task a Golftrolley with the features of the claim 1.

advantageous Further developments thereof are described in the further claims.

According to the invention is at a golf trolley with a bag-pad and a suspension between bag-pad and suspension preceded by a suspension. This allows that Jounce of the chassis opposite bag-bag with bag.

Shocks that caused by bumps or the like so cushioned and act on the bag only a small amount, so that a shake its content, in particular the bat, is significantly reduced. In order to the order of the contents of the bag, especially the racket, remains in the Maintained, the noise pollution by rattling or the like is reduced and scouring the content, especially the bat, and the associated wear is also reduced.

The Suspension may comprise a motor, in particular an electric motor, the one or more wheels drive and so the golfer while pulling or pushing the trolley support or the trolley automatically can drive. Because of the big one unsprung masses in motorized trolleys acts the present Invention particularly advantageous in such trolleys.

Prefers the suspension comprises at least one spring-damper element in which a or more springs and / or one or more dampers in series and / or in parallel are switched. By an appropriate arrangement with secondary and / or Series connection of springs and / or dampers can be any Spring-damper characteristics being represented.

When Spring are for example gas springs, air springs, mechanical Springs, in particular spiral, leaf or disc springs. As dampers come preferably air or oil pressure damper for Commitment. An advantage is a combination unit, namely a Spring dampers, with shock absorber, spring as well as Zuganschlag and pressure stop.

Prefers are Bagauflagen, suspension and / or suspension made of light metal, in particular one Aluminum or titanium alloy, and / or plastic, in particular fiber reinforced Made of plastic. this leads to for weight reduction of the sprung masses and thus a shift in the Natural frequencies in non-excited in normal operation frequency ranges.

To the Transportation can in a preferred embodiment Bag rests, suspension and / or suspension can be dismantled or folded be educated. For example, after removing a spring-damper element Suspension and bag support according to the kinematics of the suspension be folded.

Other objects, advantages and features of the present invention will become apparent from the dependent claims and the embodiments. Here to show:

1 a sprung golf trolley according to a first embodiment of the present invention for manual operation; and

2 a sprung golf trolley according to a second embodiment of the present invention for operation with an electric motor.

As in 1 pictured is a golf bag 1 detachably fastened on a golf trolley according to the invention. Similarly, golf bag 1 and Trolley also be integrally formed with each other.

The trolley includes a bag pad 2 ie a frame or the like on which the bag 1 by means of tensioning belt (not shown) is fixed, and a chassis 3 which in the embodiment shown here comprises two wheels and an axis connecting them about which the wheels can rotate.

According to the trolley further comprises a suspension 4 in the first embodiment shown here, a spring-damper element 4a and a joint rod 4b includes.

The spring-damper element 4a is for example a spring damper or a spring-damper element, as it may be present on a mountain bike. It may contain in series and / or in parallel air, gas, metal or other springs and / or air, gas, oil or other dampers. Preferably, springs and dampers are tuned to the weight, the kinematics and the use of the trolley, for example so that when a standard obstacle overrun the bag support 2 opposite the chassis 3 once performs a relative oscillation. The spring-damper element can also be blocked.

The articulated rod 4b gives with the spring-damper element 4a the kinematics of the suspension. In the example shown, the spring-damper element 4a when rolling over a floor unevenness opposite the bag support 2 spring in and out, the articulated rod 4b and suspension 3 relative to the Bagauflage 2 perform a relative movement.

For transport, the spring-damper element 4a removed, or at least its connection with the Bagauflage 2 or the chassis 3 and then the suspension 3 by means of articulated rod 4a to Bagauflage 2 folded down.

2 illustrates a second embodiment of the present invention. Again, a golf bag 1 detachably fastened on a golf trolley according to the invention. The trolley includes a bag pad 2 as well as a chassis 3 , which in the second embodiment shown here, two drive wheels 3a driven by an electric motor (not shown), a front steerable wheel 3b , as well as a frame connecting the wheels 3c includes, on which the wheels 3a . 3b are rotatably mounted.

The drive torque of the drive wheels 3a is via an operating element on the bag support 2 controlled by the golfer so that the pulling or pushing of the trolley is supported.

The suspension 4 in the second embodiment comprises two parallel spring-damper elements which, as in the first embodiment, serially and / or parallelly connected air, spiral, plate, leaf or other springs and / or air, gas, oil or other dampers. The parallel arrangement of the two spring-damper elements results in a purely vertical compression of the bag support 2 opposite the chassis 3 which ensures an ideal reaction of the suspension in view of the substantially vertically acting impacts by bumps or the like.

Other Suspension kinematics, for example, parallelogram suspension with vertical or opposite this inclined axis, are equally possible. By a slight over the vertical For example, in the direction of travel to the rear inclined suspension axis the bill due to the speed not completely vertical bumps account be worn.

For transport, the spring-damper elements 4 removed, or at least their connection with the Bagauflage 2 or the chassis 3 and then the suspension 3 and bag pad 2 be transported separately.
