    Carriage with automatic safety brake
    The invention relates to a carriage according to the preamble of claim 1.
    Figure 1 discloses a commercially available carriage 1 in a plan view, without mounted flexible seat, comprising two curved skids 2. Furthermore, the carriage 1 comprises four feet 3 and two cross struts 4, wherein over the feet 3, the runners 2 and the cross braces 4 fixed connected to each other. The carriage 1 has, in each case above the two skids 2, two spars 5, which are mounted on the transverse struts 4, along the direction of travel. The cross struts 4 form with the bars 5, the basis for the flexible seat which is formed for example with seat belts. The carriage 1 comprises a handbrake 6 which consists of an axis of rotation 7, a handbrake lever 8 and an automatic safety brake 9, which has two brake claws at the lower end and a printed sheet 10 at the upper end and wherein the axis of rotation 7 is also part of the automatic safety brake 9. The hand brake lever 8 has at the front end a handle 11 and at the opposite end two hand brake claws 12. The carriage 1 comprises two bearing blocks which receive the axis of rotation 7 in which the handbrake 6 and the automatic safety brake 9 are rotatably mounted. The automatic safety brake 9 comprises a tension spring which is connected to the front of the transverse struts 4 as seen in the direction of travel.
    Figure 2 shows the carriage 1 according to Figure 1 in a sectional view A-A, wherein the brake claws 14 engage the automatic safety brake 9 by the prestressed tension spring 13 in a roadway and the hand brake claws 12 of the hand brake 6 do not engage in the road. The two bearing blocks 15 are fixedly connected by connecting means with the runners 2.
    FIG. 3 shows the carriage 1 according to FIG. 1 in a sectional view B-B, a force F acting on the printed sheet 10 of the automatic safety brake 9 and a force Fr acting on the handle 11 of the handbrake 6. The force F is introduced for example by a, positioned on the seat, driver who also applies the force Fr by pulling the holding handle 11. The force F acts against the prestressed tension spring 13 and lifts, by rotation of the automatic safety brake 9 about the axis of rotation 7, the brake pads 14 from the road. The force Fr causes a rotation of the hand brake 6 about the axis of rotation 7 whereby the hand brake claws 12 engage in the roadway.
    The carriage shown in Figures 1-3 thus includes two additional braking systems which ensure more safety in a downhill on snow-covered roads. In commercial sleds, the driver brakes mainly with his feet, which he presses into the roadway. In this embodiment, the driver is still the
    Handbrake available, which advantageously increases the braking effect with additional use to the feet. The preloaded tension spring causes about the axis of rotation a moment on the automatic safety brake, which on the one hand presses the sheet against the flexible seat of the carriage, wherein the flexible seat limits the rotational travel of the automatic safety brake. On the other hand, the moment presses the brake claws in the road and thereby lifts the carriage from the road. When a driver bursts on the flexible seat of the carriage, the driver's dead weight (force F) acts against the signature of the automatic safety brake and, consequently, against the moment introduced by the pre-tensioned tension spring. The thus initiated rotational movement of the automatic safety brake raises the brake claws from the road and the ride can be recorded. Does it come while driving to an accident, i. the driver falls off the seat of the carriage, presses the moment of preloaded tension spring the brake claws in the road and the carriage is stopped. This prevents the sled from picking up speed and endangering other people or being damaged by an impact.
    In the embodiment shown, it has proven to be a disadvantage that the embodiment shown, the automatic safety brake inevitably engages while driving in the roadway. Especially when driving at high speed and on uneven roads, the carriage can lift off the road together with the driver which briefly acts no force on the sheet and engage the brake claws of the automatic safety brake in the road. This effect is reinforced by the fact that the brake claws shown counter to the direction of travel and their braking forces cause high forces of the sheet against the seat and can damage the seat. In particular, when the carriage is often, for example, as rental equipment, in use.
    When driving with the illustrated embodiment, the automatic safety brake can unintentionally but permanently intervene in the road and brake easily. Especially on a road surface, which is freshly prepared, the skids of the carriage sink deeper into the snow and as a result, come the brake claws of the automatic safety brake with the road permanently in touch. It has proven to be a disadvantage that the brake claws are insufficiently lifted off the roadway via the direct lever between the brake claws and the printing sheet of the automatic safety brake, in particular if the vertical path of the printed sheet is limited by the structural conditions of a commercially available carriage.
    It has proven to be a disadvantage that the additional construction of the handbrake and the automatic safety brake by the additional weight makes the slide, especially for children, more cumbersome.
    The invention is based on the object to provide a slide with an automatic safety brake with the aforementioned disadvantages can be overcome.
    According to the invention, this object is achieved in that the automatic safety brake at least one joint quadrangle, which includes a sheet, a brake claw, a coupling and a spring element comprises, wherein the brake claw and the sheet are pivotally mounted on the carriage and the coupling with the sheet and the Brake claw is hingedly connected, wherein the spring element is connected to the carriage and exerts a force on the joint quadrilateral, pivoted in the unloaded state of the carriage of the sheet substantially by the spar plane adjacent to the flexible seat, and the brake claw is forcibly guided by the skid plane pivoted , And in the loaded state of the carriage, the sheet resting against the flexible seat sheet and the brake claw are located substantially between the spar plane and the skid plane.
    A four-bar linkage or a four-link coupling gear consists of four in a plane rotatably connected rods. The four bars differ in their task and are called frame, swingarm, paddock and crank. In the kinematics, the frame is considered stationary (held) and the crank is driven. The coupling transmits the movement of the crank to the rocker. By defining the geometric conditions of the four-bar linkage, the movements of the individual bars are predefined and, as a result, the angular deflections of the moving bars are also defined. Depending on the geometric design, a small angular deflection of the crank can thus mean a greater angular deflection of the rocker or vice versa, hence the name four-link coupling mechanism.
    Further advantageous embodiments of the carriage according to the invention with automatic safety brake are explained in more detail below with reference to FIGS.

    Figure 4 discloses a carriage 21 according to the invention in an isometric view, wherein the flexible seat is not shown, comprising two curved skids 22. Furthermore, the carriage 21 comprises four feet 24 and two cross braces 25, wherein over the feet 24, the runners 22 and the cross braces 25 are firmly connected to each other. The carriage 21 has, in each case above the two skids 22, two spars 26, which are mounted on the transverse struts 25, along the direction of travel. The cross struts 25 form with the bars 26, the base for the flexible seat which is formed for example with seat belts. Furthermore, the carriage 21 comprises an automatic safety brake 27, a handbrake 28 and a suspension system 29.
    FIG. 5 shows the carriage 21 according to the invention according to FIG. 4 with the automatic safety brake 27, the hand brake 28 and a suspension system 29, the carriage 21 and the automatic safety brake 27 being shown in the unloaded state. The automatic safety brake 27 comprises an axis of rotation 30 which is fixedly connected to the rear feet 24, further two angles 31 which form a further axis of rotation 32 and for this purpose are fixedly connected to the rear transverse strut 25. The automatic safety brake 27 has two articulated quadrilaterals (see FIG. 6) which are formed from a printed sheet 33, two coupling rods 34, two brake claws 35 and the two rotary shafts 30 and 32, the connections being articulated to each other.
    A more detailed description of the four-bar linkages follows in Figure 6. The automatic safety brake 27 comprises two tension springs 36 which are biased in installation position and act in the connections between coupling rods 34 and brake claws 35 and are connected thereto at the opposite end to the rear feet 24. This positioning of the attack point of the tension springs 36 advantageously allows a particularly efficient transmission of the spring force to the joint quadrilateral with a simple construction. The use of tension springs 36 as spring elements and coupling rods 34 as coupling offers the advantage of a particularly robust and easy-to-repair construction. The kinematic relationships of the automatic safety brake 27 and the tensile forces of the prestressed tension springs 36 cause first a front end 37 of the sheet 33 against gravity acts on a flexible seat and secondly the brake claws 35 lift the rear end of the carriage 21 from the road and through the contact with the roadway produce a braking effect. It should be noted that the flexible seat surface of the carriage 21 according to the invention is not shown in FIG.
    It may be mentioned that the tension springs 36 may also be connected at another point to the carriage 21 according to the invention, or that they may also be connected to the four-bar linkage at another position.
    FIG. 6 shows in detail view D the automatic safety brake 27 of the carriage 21 according to the invention according to FIG. 4, the dashed lines representing rods of the four-bar linkage 38. The axis of rotation 30 (point R) and the axis of rotation 32 (point Q) are fixedly connected to the carriage 21 according to the invention and form a frame 39, between the points R and Q, the joint square 38. As described above, the frame of a four-bar linkage of the rod which is recorded. In this case, the frame 39 is fixedly connected to the carriage 21. The printing sheet 33 is rotatably mounted in the axis of rotation 32 and further articulated at point P with the coupling rods 34. The printing sheet 33 forms between the points P and Q a crank 40 of the four-bar linkage 38. The coupling rods 34 are pivotally connected at point S with the brake claws 35 and the coupling rods 34 form between the points P and S a coupling 41 of the four-bar linkage 38. The brake claws 35 are rotatably mounted in the axis of rotation 30 and form between the points S and R a rocker 42 of the four-bar linkage. The prestressed in installation position springs 36 act at point S of the four-bar linkage 38 and press the front end 37 of the sheet 33 against the flexible, not shown seat. A lower end 43 of the coupling rod 34 extends beyond the point S of the coupling 41. If the automatic safety brake 27 is unloaded, the lower end 43 abuts against the axis of rotation 30 and serves as a travel limit for the tension springs 36. This has the advantage that the Path of the front end 37 is limited in the direction of flexible seat and the flexible seat thereby does not have to absorb the entire forces of the tension springs 36. About the thus formed four-bar linkage angular relationships between the deflection of the sheet 33 and the deflection of the brake claws 35 35. The four-bar linkage 38 is formed so that a small angular deflection of the sheet 33 results in a larger angular deflection of the brake claws 35, whereby the advantage is obtained that at
    Loading the sheet 33, the brake claws 35 stand out from the roadway, as if the sheet is connected to the brake claws via a simple lever.
    It may be mentioned that the four-bar linkage can be arranged differently on the carriage, for example that the point Q, seen in the direction of travel, can lie behind the rear cross-member, or that the point R, seen in the direction of travel, can be positioned in front of the rear feet , Furthermore, it should be mentioned that the individual rods of the four-bar linkage can be assigned to other parts, for example, that the axes of rotation of the frame with the spars or runners can be firmly connected, and that instead of or with the four-bar linkage other types of coupling gears be installed can.
    Figure 7 shows the carriage 21 according to the invention according to Figure 4, wherein the carriage 21 and the automatic safety brake 27 are shown in the loaded state. The load is carried by the driver placed on the flexible seat, this is shown schematically in Figure 7 as a force F. By seating the driver, the front end 37 of the sheet 33 is moved in the direction of the roadway and further biased by the connection via the coupling rods 34, the tension springs 36 and the brake claws 35 lifted from the road. The intervention of the brake claws 35 according to the invention does not occur counter to the direction of travel, thereby the advantage is obtained that in kurzeitigen lifting the carriage 21 with the driver, the brake claws 35 do not wedge in the road and thus also act no unwanted loads on the flexible seat. Furthermore, there is an advantage that the brake claws 35 stand out further from the roadway as a result of the arrangement of the four-bar linkage, when the driver sits on, than if the brake claws 35 are connected to the pressure bend 33 via a simple lever.
    Figure 8 shows a carriage 51 in an isometric view, wherein the flexible seat is not shown. The carriage 51 comprises the suspension system 29, an automatic safety brake 52 and a fall brake 53. In this preferred embodiment, a left hand brake lever 54 and a right hand brake lever 55 are integrated in the automatic safety brake 52, as well as the coupling of the four-bar linkages designed as ropes 61. By integrating the handbrake lever 54 and 55 in the automatic safety brake 52, the advantage is obtained that thereby no own axis of rotation and brake claws for the handbrake are necessary and therefore the weight of the carriage 51 according to the invention is reduced. The left and right hand brake levers 54 and 55 extend laterally outwardly below the flexible seating surface. As a result, the advantage is obtained that, for example, drive two persons with the carriage 51, the rear person easier to the handbrake levers 54 and 55 passes as in the previous embodiments. Especially when, for example, an adult (rear person) is traveling with a child (front person) with the carriage 51.
    Figure 9 shows the carriage 51 according to the invention according to Figure 8, in a sectional view. The automatic safety brake 52 comprises two axes of rotation 56 and 57, the axis of rotation 56 is fixedly connected to the rear cross member 25, and the axis of rotation 57 is fixedly connected to the rear legs 24. The straight connection of the two axes of rotation 56 and 57 forms the frame of a four-bar linkage with the points P, Q, R and S. Furthermore, the automatic safety brake 52 comprises a pressure sheet 58 with a front end 59 and two leg springs 60. The axes of rotation of the leg springs 60 lie in the axis of rotation 56, wherein the leg springs 60 are biased in the installed position and act between the rear cross member 25 and the printed sheet 58. As a result, the printed sheet 58 presses against the flexible seat, not shown. The use of a leg spring 60 in this installation position advantageously leads to a reduction in the space requirement of the automatic safety brake 52. The straight line between the points P and Q of the pressure sheet 58 form the crank of the four-bar linkage. The right and left hand brake levers 55 and 54 (see FIG. 8) are rotatably supported in the rotation shaft 57, and the points S and R of the hand brake levers 54 and 55 constitute the rocker of the four-bar linkage. The automatic safety brake 52 includes two ropes 61 which connect the Dmckbogen 58 with the handbrake levers 54 and 55. The connection takes place at the points P of the printed sheet 58 and the points S of the hand brake levers 54 and 55. The tensioned cables 61 form the coupling in the four-bar linkage and are flaccid when the automatic safety brake 52 is loaded (see FIG. 10). The hand brake levers 54 and 55 each have a brake claw 62 at the rear end. By using the ropes 61 instead of the coupling rods 34 (see FIGS. 5 to 7) as in the preceding exemplary embodiment, the advantage is obtained that the brake claws 62 of the handbrake levers 54 and 55 can also be used for the automatic safety brake 52. The ropes 61 are stretched with unloaded automatic safety brake 52 and the handbrake levers 54 and 55 are rotated about the axis of rotation 57 so far that the brake claws 62 engage the road and the rear part of the carriage 51 is lifted from this.
    It may be mentioned that other types of springs or spring mechanisms may be used instead of the illustrated types of springs. For example, one type of leaf spring may be integrated in the flexible seating surface. Furthermore, it can be mentioned that instead of the ropes also coupling rods can be used with slots.
    FIG. 10 shows the carriage 51 according to the invention in accordance with FIG. 8, in the same sectional view as FIG. 9, wherein the carriage 51 and the automatic safety brake 52 are shown in the loaded state. The load is carried by a placed on the flexible seat driver represented by the force F. The handbrake levers 54 (see FIG. 8) and 55 have two handles 63 at the front end. The
    Hand brake levers 54 and 55 are designed so that only by their weight distribution, with free rotation about the axis of rotation 57, the handles 63 sink towards the road. The driver's weight acts over the signature 58 against the biased leg springs 60 and rotates the signature 58 toward the roadway. As a result, also the point P of the printed sheet 58 lowers and the handles 63 sink in the direction of the roadway and the brake claws 62 lift off the roadway. On the slack shown ropes 61 depends only more of a part of the weight of the hand brake lever 54 and 55. This has the advantage that the hand brake lever 54 and 55, with loaded automatic safety brake 52, can be rotated and their brake claws 62 also part of the automatic safety brake 52 are. Furthermore, the coupling by ropes has the advantage that the right and left hand brake levers 54 and 55 are independently operable and thus cornering by the hand brake levers 54 and 55 are introduced.
    It should be noted that the handbrake levers can be firmly connected to each other and engage by the operation of a handbrake lever both brake claws in the road and that instead of ropes and other pliable components, such as chains, can be used. Furthermore, it should be mentioned that the handbrake, for example, may have bowden cables.
    The suspension system 29 comprises a holding frame 64 and a suspension hook 65. The support frame 64 is fixedly connected to the two bars 26 and has a rotation axis 66 and a holding handle 67. The suspension hook 65 comprises at the upper end a handle 68 and at the lower end two hooks 69. About the rotation axis 66 of the hooks 65 is rotatably connected to the support frame 64. With the suspension system 29 shown a safe uphill ride on the towing or platter lift is guaranteed. At the entrance of the tow, the driver includes with his hands the handles 67 and 68, then the bracket of the towing device is hooked into the two hooks 69 and the driver with the carriage 51 is pulled up. At the exit of the drag lift, the driver lets go of the two holding handles 67 and 68 and the suspension hook 65 folds, due to the pulling force of the towing device, about the axis of rotation 66. By folding in the suspension hook 65, the bracket of the towing device dissolves and the driver can leave the exit point.
    It should be noted that the suspension system in alternative embodiments ropes or closures, which are still easy to open even under heavy load, may have. As examples of such closures are snap shackles from yachting or panic hacking from equitation mentioned.
    Another safety device on the carriage 51 for the uphill drive on the tow bar is the fall brake 53. The fall brake 53 comprises a rotation axis 70, a fall brake claw 71 and a stop 72. The fall brake claw 71 consists of a lower end 73 and a
    Stop end 74. The axis of rotation 70 and the stop 72 are fixedly connected to one of the front feet 24. By the rotation axis 70, the fall brake claw 71 is rotatably connected to the carriage 51, wherein the rotation (see arrow) by the stop 72 and the stop end 74 is limited. The fall brake claw 71 and its mounting in the axis of rotation 70 are designed so that while driving the lower end 73, without noticeable braking effect, permanently touches the road. Dissolves during the uphill on the drag lift unintentionally the bracket, or breaks the tow rope, there is a short reverse drive and the drop brake claw 71 wedged in the road and twisted until the stop end 74 touches the stop 72. The carriage 51 comes to a standstill with the driver and can safely leave the towpath. The fall brake 53 prevents accidental reversing of the carriage 51st
