Description

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

Golf carts of this type are known (e.g. G 93 19 449.8, US Pat. No. 5,048,856, DE-OS 22 27 990). In the known golf carts, the chassis basically consists of two Struts, each articulated about a chassis pivot axis on the frame element are, in such a way that the chassis pivot axis with each other and with the Make an axis of the wheels at an angle so that when the chassis is pivoted with the drawbar in the non-use position, the two struts not only to the Frame element, but also pivoted close together. Disadvantageous here is on the one hand a large number of individual parts and a lack of stability, however also the fact that the wheelbase changes with the pivoting of the drawbar changed and thus an adjustment of the position of the drawbar in relation to the Frame element is not possible. It is also known to have a golf cart To provide electric drive (DE-OS 22 27 990, DE-OS 35 11 461).

The object of the invention is to show a golf cart that is simplified Construction has a high stability. To solve this problem is a Golf cart designed according to claim 1.

In FIGS. 1-6 with 1 generally designates a golf cart. This includes, among other things, a flat, rectangular frame element 2 , on the underside 2 '''of which a drawbar 3 is pivotally provided in the center of one narrow side 2 ' and on the two narrow struts 4 one between the narrow side 2 'and the opposite narrow side 2 '' Chassis 5 are pivotally attached, namely each strut 4 with one end on a long side of the frame element 2 . The pivot axes of the drawbar 3 and the struts 4 are each oriented perpendicular to the plane of the long side of the frame element 2 . Via a rod 6 , the drawbar 3 and the chassis 5 are connected to one another in terms of drive, so that when the drawbar 3 is pivoted from the position of use shown in FIG. 1, in which the drawbar 3 protrudes over the narrow side 2 ', into the non-use or Transport position in which the drawbar 3 is adjacent to the underside 2 '''of the frame element 2 , the chassis 5 is also pivoted towards the underside 3 ''' of the frame element 2 , so that the golf cart 1 is small and compact in this transport state and thus is easy to transport.

On the upper side 2 '''opposite the lower side 2 '''' 7 pockets 7 are provided on the frame element for accommodating a wide variety of golf utensils. In the interior of the frame member 2, a plurality extending in the longitudinal direction of this frame member quiver 8 are formed, which are closed at the short side 2 'is open and on the narrow side 2' 'and in which the golf club 9 can be inserted with its shaft advance. The quiver are arranged in two rows, with their quiver axes in two planes parallel to the underside 2 '''.

As can be seen in FIG. 2, in addition to the two struts 4 , the chassis 5 also comprises a lower cross strut 10 connecting the struts 4 , which, like the struts 4, is made from a metal or tubular steel profile, namely from one Pipe profile with a cross-section deviating from the circular shape, ie with a rectangular cross-section in the embodiment shown. The cross strut 10 is open at both ends, as indicated in FIG. 2 by 11 for one end, so that a wheel carrier 12 can be inserted into the cross strut 10 from both sides, which is adapted from a cross section of the cross strut 10 Metal profile and on which a wheel 13 is rotatably mounted.

On each wheel carrier, a resilient locking element 14 is provided, which, after the wheel carrier 12 has been pushed into the opening 11, engages in a hole 15 provided in the cross member 10 , so that the wheel carrier 12 is locked on the chassis 5 , but this locking is carried out by depressing the locking element 14 can be solved again.

In FIGS. 3-6, 16 generally designates an electric drive which, instead of the wheels 13 , can be fastened to the underside of the chassis 5 in the area of the cross strut 10 there, with only a few hand movements. The drive 16 consists essentially of a sheet steel subframe 17 , which forms, among other things, a wall 18 which extends over the entire height and width of the subframe 17 and is provided on two longitudinal sides with a bend 19 each, each of which in the wegstehen of FIG. 6 of the left side wall 18. Also on the left side of the wall 18 , this forms an angled portion 20 on the underside of the auxiliary frame 17 , which extends across the entire width of the auxiliary frame and connects the two angled portions 19 to one another. The bends 19 lie in planes perpendicular to the plane of the bend 20 . Furthermore, the planes of the bends 19 and 20 are each perpendicular to the plane of the wall 18 .

At the edge remote from the wall 18 , the bend 20 is further provided with an angled edge 21 which protrudes somewhat beyond the side of the bend 20 facing the bend 19 . The distance between the bends 19 is such that the chassis 5 can be inserted between the bends 19 when the wheels 13 are removed, so that the cross strut 10 bears against the side of the bend 20 facing the wall 18 or the top of the subframe 17 and on the one hand supported on the wall 18 and on the other hand on the protruding edge 21 , the struts 4 each rest with their sides facing away from an angled portion 19 and are also supported on the side of the wall 18 facing the angled portions 19 . For clie connection of the subframe 17 to the chassis 18 4 spring-like locking elements 22 are provided on the opposite sides of the struts 4 , which can snap into a hole 23 of the bends 19 , so that between the subframe 17 and the chassis 5 again releasable quick or snap connection is reached. The subframe 17 thus forms a receptacle in which the chassis 5 can be anchored after it has been inserted.

On the side of the wall 18 opposite the bends 20 , a carrier 24 is also fastened to the underside of the auxiliary frame 17 and forms, among other things, a battery compartment 25 for receiving a rechargeable battery and a housing 26 for receiving an electronic control. With the underside of the auxiliary frame 17 is attached to the outer surface of a tubular housing 27 , which lies with its axis parallel to the plane of the wall 18 and in which, among other things, an electric motor with a gear for driving the wheels 28 rotatably mounted on one end face of the housing 27 is accommodated is.

The drive 16 forms a fully functional unit, ie after the drive 16 has been fastened to the chassis 5 , only a control cable 29 has to be connected to a socket 30 on the housing 26 in order to connect the drive 16 to a control element with which the functions of the drive 16 can be controlled, ie the switching on and off of the electric motor, the regulation of the rotational speed and direction of rotation of the drive wheels 28 etc.

In the embodiment shown in the figures, this control and operating element is a sensor 31 , which is provided between the end of the drawbar 3 remote from the frame element 2 and a drawbar handle 32 there and is designed such that it has a low tensile force between the drawbar handle 32 and the drawbar 3 switches on the drive for a motor-driven movement of the golf cart in this pulling direction (arrow A) and, with a small pressure force on the drawbar 32, switches on the drive for an opposite movement of the golf cart 1 , ie in the direction of arrow B in FIG. 3, while the drive 16 is switched off when there is no force on the tiller handle 32 .

When the drive 16 is mounted on the golf cart 1 , the previously dismantled wheels 13 are carried along with the golf cart 1 . For this purpose, a profile 33 corresponding to the cross strut 10 is fastened to the underside 2 ″ ″ of the frame element 2 in the vicinity of the narrow side 2 ″, to which the wheels 13 can be fastened by inserting and latching the wheel carriers 12 , in the same way Way as described above for the attachment of the wheel carrier 12 to the cross strut 10 . After attaching the wheels 13 to the profile 33 , these are axially aligned with one another and lie with their axes also parallel to the axis of the driven wheels 28 , so that the golf cart 1 in the manner shown in FIG. 3 with a total of four wheels 13 and 28 on the Gets up.

Carrying the wheels 13 has the advantage that, for example when the battery of the drive 16 is depleted, it can be conveniently detached from the chassis 5 and the wheels 13 can be fastened instead of the drive 16 , so that the golf cart 1 can then be moved at least by hand. The drive is deposited at a suitable location on the golf course and later collected with a vehicle and transported to recharge the battery.

FIGS. 7 and 8 show a further embodiment of a golf cart 1 a which is substantially differs from the golf cart 1 of Fig. 1 in that, instead of the frame member 2, two frame members 2 a and 2 b are provided, each shallow than the Frame element 2 are executed and of which the frame element 2 a is provided with the drawbar 3 and the chassis 5 in the same manner as described above for the frame element 2 . On the narrow side 2 a '' and 2 b '' of the drawbar 3 , the two frame elements 2 a and 2 b are connected to one another via a joint 34 , so that pivoting of the frame element 2 b about a parallel to the axis of the wheels 3 extending axis is possible by a certain angular amount relative to the frame element 2 , namely between a state of use ( Fig. 7), on which the two frame elements 2 a and 2 b are spaced apart from one another on their end face 2 a 'and 2 b', and a transport position ( Fig. 8) in which the two frame elements 2 a and 2 b rest on each other. The frame elements 2 a and 2 b each contain only one row of the quivers 8 open on the narrow side 2 a ′ and 2 b ″.

By designing the golf cart 1 a it is achieved that the golf clubs are spaced apart cler two rows of tubulars 8 in the use state of the golf caddy 1 and hence do not hit the golf club when driving the golf cart 1 a in the area to each other. In order not only to pivot the chassis 5 a into the use position when transferring the drawbar 3 from the non-use position into the use position, but also to pivot the two frame elements apart about the joint 34 , the struts 4 a of the chassis 5 a are each a lever 35 is provided which, when the chassis 5 a is pivoted into the use position, also swings the two frame elements 2 a and 2 b apart.

The sensor 31 is shown in more detail in FIGS. 9-11. The three mutually perpendicular coordinate axes (X-axis, Y-axis and Z-axis) are entered in FIGS. 9-11 for easier orientation.

This sensor consists of two, in the embodiment shown block-like sensor bodies 36 and 37 , which are each made in one piece with a connecting piece 36 'or 37 ' made of metal. The connector 36 'is attached to the frame member 2 and a 2's remote end of the drawbar 3 is attached by insertion into a drawbar 3-forming tubular profiles. The tiller handle 32 is fastened to the connecting piece 37 ', so that the central plane of the tiller handle 32 coincides with the central axis of the tiller 3 . Accordingly, the longitudinal extensions of the connecting pieces 36 'and 37 ' lie in a common central plane M, which is the XY plane.

The connections 36 'and 37 ' lie with their longitudinal axis in the X-axis. In the embodiment shown, the two sensor elements 36 and 37 are offset from one another in the direction of the Y-axis and are held at a distance from one another in the direction of this axis, so that a gap 38 is formed between them, which lies essentially in the XZ plane. Furthermore, the two sensor elements 36 and 37 can be moved relative to one another in the X-axis from the initial position or rest position shown in FIGS. 9-11, specifically in two opposite directions, ie in the direction of arrow C (in the case of FIG 9 chosen representation. to the right) and in the direction of arrow D (in the place chosen for Fig. 9 illustration to the left), in each case against the action of a spring force. In the area of the gap 38, a guide is provided against undesired rotation about the Y axis and against undesired displacement of the sensor elements 36 and 37 relative to one another in the area of the gap 38 , which extends from the groove 39 in the sensor element 36 and into the groove Web 40 is formed on the sensor element 37 . In the normal state, the two sensor elements 36 and 37 are also spaced apart from one another in the region of this groove 40 .

With 41 bow springs made of spring wire are designated. These springs 41 have a multiple function, ie on the one hand they provide a defined gap width (gap 38 ) between the sensor elements 36 and 37 and on the other hand they also form double-acting return springs with which the two sensor elements 36 and 37 are held in their initial position that in the illustrated embodiment, the sensor elements 36 and 37 coincide in a way perpendicular to the XZ plane.

Each bracket 41 is made from a length of spring wire by a U-shape and has two legs 41 ', which have a predetermined distance from each other and a bracket section 41 ''connecting these legs together. The springs 41 are arranged in the region of the corners of the sensor elements 36 and 37, which are essentially square in plan view of the XZ plane, in such a way that the straight bracket portion 41 ″ of each spring 41 lies in the Y-axis, and in part in a groove 42 formed on the outer surface of the sensor element 36 and partially in a groove 43 adjoining this groove 42 on the outer surface of the sensor element 37 and thereby bridging the gap 38 . The grooves 42 and 43 are provided on the two side or circumferential surfaces of the sensor bodies 36 and 37 lying in the XY plane, namely two such grooves 42 and 43 on each of these circumferential sides. The grooves 42 and 43 are further designed so that their width is slightly larger than the cross section of the spring wire used for the springs 41 .

On the sides 36 '' and 37 '' facing away from one another and lying in the XZ plane, the sensor bodies 36 and 37 are provided with two intersecting grooves 44 , which run approximately diagonally and in each case at both ends in a groove 42 (on the Surface 36 '') or both ends in a groove 43 (on surface 37 ''), each groove 44 with one end in a groove 42 adjacent to the connector 36 'or in a groove 43 adjacent to the connector 3 T and with the other end in a groove 42 distant from the connector 36 'or in a groove 43 distant from the connector 37 '. In the illustrated embodiment, the grooves 44 each enclose an angle of 45 ° with the XY plane with their longitudinal extent. Furthermore, the grooves 44 are formed so that their depth and width is slightly smaller than the diameter of the spring steel used for the springs 41 .

The springs 41 are mounted so that each spring is received with its bracket arm 41 '' in a groove 42 and a groove 43 and lies with each leg 41 'in a subsequent groove 44 , with a leg 41 ' in a groove on the side 36 '' and with a leg 41 on the side 37 ''. The springs 41 are clamped with their legs 41 'in the grooves 44 between the respective sensor bodies 36 and 37 and a screwed-on cover 45 , so that the springs 41 are thereby secured not only to the sensor bodies 36 and 37 , but by the distance between them Leg 41 'also the gap width for the gap 38 is observed.

The plane of each stirrup spring 41 formed by the legs 41 ′ and the respective stirrup arm 41 ″ is at an angle of 45 ° to the X axis or the YZ plane. As a result, the yoke springs 41 are resiliently deformed when the sensor bodies 36 and 37 move relative to one another in the X axis, in particular in the area of their yoke arm 41 ″, without the legs 41 ′ twisting about their longitudinal extent in the area of the grooves 44 . The resilient restoring force for the sensor 31 is thus achieved by the springs 41 .

A bore 46 with its axis in the X axis is provided in the sensor body 37 . In this bore there is a contactless electrical signal generator 47 , ie in the embodiment shown an inductive signal generator is arranged which interacts with its active area with a metal plate 38 attached to the sensor body 36 and the distance between these metal plates 48 and the signal generator 47 and thus one provides the relative displacement between the sensor bodies 36 and 37 corresponding electrical signal. This is passed over the control cable 29 to the control device 26 and converted there into a signal controlling the drive 16 , in such a way that the drive is switched off when the sensor bodies 36 and 37 are in the starting position, and that the drive 16 is in the event of a relative movement of the Sensor body 37 to the sensor body 36 in the direction of arrow C, ie when the tiller handle 32 is pulled, the golf cart 1 or 1 a for movement in the C direction and when the tiller handle 32 is pressed, ie when the sensor body 37 is moved relative to the sensor body 36 in the direction of arrow D drives the golf cart 1 or 1 a for a movement in the direction D.

The sensor 31 described is characterized by a simple structure. In particular, the bow springs 41 are simple and yet can be produced with the required high accuracy. These bow springs and thus the sensor 31 as a whole have a long service life.
