    Austrian Patent Office AT13 396U1 2013-12-15
    Description: [0001] The invention relates to a carriage, in particular a handcart for the transport of fire-brigade equipment, with a carriage frame to which a loading surface and rollers arranged in pairs on axles are assigned.
    In addition, the invention relates to a role, in particular a steering roller for use on hand trucks.
    Such a car is known from DE 20 2010 005 525 U1, which can be used either on normal road surface or on rails. This type of cart has proven particularly useful in cases of train accidents or accidents in remote forest areas where rails are routed, as they are quick and easy to get to the jobsite. The use of such a car, however, still has the disadvantage that it can not be blocked in a simple manner in its movement, since each of its roles each has its own, to be operated and detected brake. This makes the handling of this car for the user consuming, if he wants to park it, for example, on an inclined plane.
    It is recommended by the fire brigades that care be taken in the manufacture of trolleys for the transport of fire brigade equipment that accidents, injuries and mishandling of the cars are prevented. These cars should be simplified, as safe and practical as a tool for device transport and material supply at the site be used. This requires that a handcart for the transport of firefighting equipment has a brake that prevents the cart from rolling on a slope of 7 degrees, which corresponds to about 12 percent incline.
    It is therefore an object of the present invention to provide a car, in particular a handcart for the carriage of fire fighting equipment, which has a corresponding to the needs of the fire departments braking mechanism, with constant flexibility of use.
    Moreover, it is the object of the invention to provide a roller of the type mentioned, which has an improved braking function.
    The object relating to the car is achieved in a carriage of the type mentioned in that at least two, preferably all of the rollers are formed as a drum brake having castors, and that the drum brakes are actuated by means provided on the carriage frame brake linkage.
    This has the advantage that the car on inclines, as often occurs in uneven field use of fire departments, can not roll away. In addition, the car does not roll when loaded, especially heavy equipment to be loaded on him. Another advantage is the use of the brake linkage, as this can not relax, such as a Bowden cable. In addition, a Bowden cable would bring with it the great disadvantage that it could get caught up faster in other equipment positioned on the fire engine or in the scrub of rough terrain at the job site.
    To be particularly favorable, it has proven to be when the brake linkage is actuated bar via a brake lever mounted on a handle. Here, the solution or the detection of the drum brakes for the user is facilitated. This may in particular be a parking brake or so-called dead man's brake, which automatically locks itself as soon as the user releases the brake lever.
    In order to protect the brake linkage from external influences, it has been found preferable that the brake linkage is arranged on the inside of the carriage frame and is preferably guided in guide rails.
    It is also useful if the brake linkage has several deflection joints, which 1/9 Austrian Patent Office AT 13 396 Ul 2013-12-15
    Pivoting radius is preferably less than half the frame height of the carriage frame and / or the brake linkage is covered by the carriage frame. By this deflection joints the necessary power transmission of the force exerted by the user on the brake lever force can be distributed to the drum brakes. A small pivoting radius and a covering of the brake linkage from the carriage frame also protects the brake linkage from external influences.
    It is also preferable if each of the rollers is associated with one of the deflecting joints, which is in each case connected to an adjustable in Wagenrahmenlängsrichtung actuating mechanism for the drum brakes. Here, the braking force is transmitted by the reversing joints in a simple way to the drum brakes.
    A particular embodiment is characterized in that the actuating mechanism is formed by means of an interacting with a cam control member having pivot axis. This pivot axis converts the horizontally extending movement of the brake linkage into a vertical movement for actuating the drum brakes.
    In order to easily transmit the braking force to the brake linkage for the user, it has proved to be beneficial when the brake lever is actuated by a vertical adjustment or by tilting about a tilt axis.
    It is also advantageous if the castors have provided for determining the direction locking lever. This ensures that the car does not drift in a direction in which he should not roll.
    The role of the task is solved by a role of the type mentioned by an opening provided in the roll inside drum brake, This drum brake provides a particularly strong and secure locking the role. This is necessary for cars, especially for hand trucks, which are loaded or loaded with very large weight.
    In order not to drive the car in an unwanted direction, it makes sense if the role is formed as a steering role with a provided for determining the direction of locking lever.
    In the following the invention is explained in more detail in an embodiment shown in the drawing; Fig. 2 Fig. 3 Fig. 4 Fig. 4 is a perspective view of the carriage according to the invention, a top view of the carriage of Fig. 1, the section FIG. 2 shows a longitudinal section through a roller with a drum brake according to the invention, and a representation of the roller from FIG. 4 cut in half by 90 degrees about the vertical axis.
    In the figures 1 to 3, a carriage, in particular a handcart 1 for the carriage of fire fighting equipment, with a carriage frame 2, which is associated with a loading area 3 and on axes 4 paired rollers 5 is shown. Each of the rollers 5 is formed as a drum brake 6 having castor and the drum brakes 6 are actuated by means provided on the carriage frame 2 brake linkage 7.
    The brake linkage 7 itself is actuated by a brake lever 9 mounted on a handle 8. This brake lever 9 is actuated by a vertical adjustment.
    In the illustrated embodiment, the brake linkage 7 is arranged on the inside of the carriage frame 2 and guided in guide rails 10. In this case, the brake linkage 7 has a plurality of deflection joints 11, which are likewise covered by the carriage frame 2. In this case, each of the rollers 5 is associated with one of the deflection joints 11, which in each case is connected to an actuating mechanism 12, which is adjustable in the longitudinal direction of the carriage frame, for the drum brakes 6.
    In the figures 4 and 5, an embodiment of the rollers 5 is shown, wherein the actuating mechanism 12 is formed by means of a one with a control cam 13 interacting control member 14 having pivot axis 15. This pivot axis 15 pushes down a bolt 17, which actuates a pivotable about a brake axis 18 lever 19 interacting with the brake shoes 20 roller brake element 21. As a result, the brake shoes 20 are pressed against the drum 22 and the roller 5 braked.
