Definitions

  • the invention relates to a device for removing coverings laid on flat surfaces with a support frame for mounting drive wheels and for receiving a motor and a transmission for driving the drive wheels and with a motor-driven cutting knife.
  • Coverings laid on flat surfaces such as carpet coverings laid on floors, are glued to their contact surface when laid. This prevents the pads from slipping and shifting when driving or walking on them. If such coverings are to be replaced by new coverings due to wear or damage, the old coverings must first be removed.
  • Such a device for removing floor coverings is known from German utility model DE 76 18 703.6.
  • a motor and a gear for driving the cutting knife are arranged on a frame with a handle for moving the device forward.
  • Two guide wheels are provided opposite the separating knife, which make it easier to guide and move the device forward when removing a floor covering.
  • US Pat. No. 4,394,052 describes a device for lifting off a floor covering, in which an electric motor and a hydraulic cylinder for driving a tremometer and a device for winding up the raised floor covering are provided on a frame.
  • This device is very bulky and very cumbersome to use.
  • the invention has for its object to provide a generic device that is simple and clear and allows energy-saving and convenient handling.
  • the invention is characterized in that at least one loosely rotatable support element is arranged parallel to the drive wheels on the support frame.
  • This measure has the great advantage that at the end of a detached piece or a detached web of a covering, the device by tilting it onto the
  • Support surface pressed, loosely rotatable support element can be supported. As a result, the drive wheels are lifted off the support surface. As a result, the
  • the drive wheels can at
  • Direction of rotation can not be switched, which protects and simplifies the electrical device of the device - or its drive can be switched off during the movement back of the device by means of a suitable on and off switch.
  • the drive wheels come back with the
  • the support element can be arranged behind the drive wheels in the direction of the forward movement of the device. It can be designed as a single wide support roller, which is arranged centrally to the drive wheels.
  • An alternative is to design the support element in the form of at least two support wheels and, if necessary, to arrange it in the area behind the drive wheels.
  • a wide support roller or support wheels arranged at a distance from one another give the device secure stability when the device for lifting the drive wheels and the cutting knife is tilted onto the support roller or the support wheels.
  • at least one guide handle is provided at the upper end of the support frame above the support element.
  • the overall structure of the device can be such that the supporting frame is formed from two legs spaced apart from one another, preferably of the same shape and size, the legs being able to converge at their upper end to form a guide handle.
  • the drive wheels are mounted at the other end of the legs.
  • the drive motor and the gear for driving the drive wheels can be accommodated on the support frame, for example between the legs forming the support frame.
  • the arrangement of the individual components can be such that the transmission is arranged directly above the drive wheels.
  • a preferred further development provides that a support plate is provided in the area of the drive wheels.
  • Each support plate has at least two bolts which are arranged at the same distance from the center of the axis of the drive wheels and which engage in elongated holes in the form of circular segments in the support frame.
  • FIG. 1 shows an embodiment of the device according to the invention in the working position in a schematic, not to scale representation in a side view
  • FIG. 2 shows the device according to FIG. 1 in a schematic representation, not to scale, in a view in the direction of arrow A in FIG. 1,
  • FIG. 3 shows the device according to FIG. 1 in the rest position in a schematic, not to scale representation in side view
  • FIG. 4 shows the device according to FIG. 3 in a schematic representation, not to scale, in a view in the direction of arrow B in FIG. 3
  • 5 shows a support frame in the form of a leg in a schematic, not to scale representation in side view
  • FIG. 6 shows the leg according to FIG. 5 in a schematic, not to scale representation in a view in the direction of arrow C in FIG. 5,
  • Figure 7 shows the support plate of the device of Figure 1 in a schematic, not to scale representation in side view.
  • the device 10 has a support frame 11, which is formed by two parallel and spaced legs 12, 13 of the same shape and size.
  • the legs 12 and 13 converge in their upper end to form a guide handle 14, on which the device 10 is held and guided during its operation.
  • drive wheels 16 are mounted about an axis 15 provided therein, which drive the device 10 for lifting off a covering in a forward movement.
  • a motor 17 and a gear 18 are provided for driving the drive wheels 16, the gear 18 carrying the motor 17 being firmly connected to the legs 12, 13 via a support plate 19 arranged on both sides thereof.
  • two support wheels 21, which act as a support element and can be rotated loosely about an axis 20, are provided behind the drive wheels 16 on an extension arm 22 formed on the legs 12, 13. The task and effect of these support wheels is described below.
  • a separating knife 25 is articulated by means of a base plate 27 to the support plate 19 by means of screws 26.
  • a drive motor 28 for the cutting knife 25 is on the support plate 19 arranged, the latter in an abrupt swinging movement to lift the surface.
  • the two drive wheels 16 are seated on the support surface 30 and drive the device 10 forward due to the ground friction in order to lift a covering from the support surface 30.
  • the cutting knife 25 lies with its cutting edge on the support surface 30 so that it can work between the covering and the support surface 30.
  • the support wheels 21 hang in the air above the contact surface 30.
  • the device 10 After a piece or a web of the covering has been lifted off, the device 10 must be moved back to a new place of use. Therefore, the device 10 can be placed on the support wheels 21 before it is moved back by a tilting movement in the direction of arrow D, as a result of which the drive wheels 16 are lifted off the support surface 30 (cf. FIGS. 3 and 4). In this process, the bolts 23 run against one end of the elongated holes 24, so that the drive wheels 16 and the cutting knife 25 hang in the legs 12, 13. Now the device 10 can be pulled back to the new location in a comfortable backward movement. The motor 17 and also the drive motor 28 can continue to run without this interfering with the return movement of the device 10.
