Definitions

  • the present invention relates to a device for pulling a boot off the foot, with a mouth that partially surrounds the boot.
  • Such devices are commonly referred to as "Stiefelknecht" and are known as a wooden plate resting on the floor at a certain angle or as a cast iron part.
  • Stiefelknecht When pulling off narrow boots, there is now a risk with such known devices that the sensitive upper leather is scratched and unsightly. In addition, there is a risk in the known devices that the boot tears in the area of its heel.
  • the present invention has set itself the task of perfecting the known device in such a way that it enables a boot to be easily removed from the foot without impairing the surface of leather boots.
  • the invention is essentially characterized in that the mouth has a lining made of elastic material, the surface of which comes into contact with the boot has a Shore hardness of at most 60 shore A, preferably between 20 and 60 shore A.
  • This elastic lining protects the surface of the boot and at the same time increases the friction between this surface of the boot and the mouth.
  • the boot as was also customary in the known devices, must be inserted into the mouth with its heel area, and the bearing surface of the device on the floor can be held down, for example, with the other foot.
  • the lining preferably consists of elastomeric plastic, preferably polyurethane foam. In this way, a sufficient coefficient of friction against leather achieved.
  • the height of the mouth is greater than the inside width and preferably corresponds to at least twice the inside width of the mouth.
  • the clamped length of the heel area of the boot is significantly increased compared to the known designs and the frictional engagement extends over this entire length, so that considerably lower forces are exerted on the upper leather of the boot in the individual partial areas of this length.
  • the lining of the mouth preferably has a profiling which can be formed by ribs or lamellae which are arranged at a distance from one another transversely to the axis of the mouth.
  • This profile can also be formed by suction cups or inflatable air chambers.
  • the ribs or lamellae lie in planes which are inclined downwards in relation to the axis of the mouth in the direction of the mouth opening. In this way, a frictional engagement is achieved very quickly by compressing the ribs or lamellae, which enables the boot to be pulled off without damage.
  • the jaw axis is inclined to the support surface of the device on the floor at an angle of 50 to 70 ° upwards towards the base of the mouth, thereby taking into account the movements when the boot is removed.
  • the device according to the invention is designed according to a preferred embodiment such that the lining is designed as an insert which is inserted in a holder surrounding the mouth, which is formed by two side walls, the side walls preferably being connected by a web to form a U-shaped profile .
  • the lining is designed as an insert which is inserted in a holder surrounding the mouth, which is formed by two side walls, the side walls preferably being connected by a web to form a U-shaped profile .
  • the distance between the side walls decreases in the height direction and the insert part forming the lining can be displaced in the height direction between the side walls, the displacement path being limited at the top.
  • an increasing contact pressure of the lining against the outside of the boot is achieved by moving the insert part upwards.
  • the insert forming the lining is guided in the direction of displacement and secured against coming out of the holder.
  • the contact pressure of the lining of the mouth on the outside of the boot can also be increased in a simple manner in that the insert part is designed as an inflatable air cushion, the walls of which form the lining, again advantageously a design is chosen in which the contact surface of the Device on the floor has a further deformable air cushion, which is connected to the air cushion (s) of the insert part. If with such a device on the deformable air cushion on the support surface of the front. direction is kicked with the other foot, are inflated by the air cushions forming the lining and pressed against the outside of the boot. The change in the arrival.
  • pressing pressure of the elastic lining on the outside of the boot can also be done by any mechanical means and the arrangement can be made so that the side walls encompassing the lining can be pressed towards one another and with the jaws released, preferably on the contact surface the device on the floor a lever is pivoted about an axis substantially parallel to the base plate, and that this lever via ropes and / or further lever is connected to the movable side walls.
  • the design can be such that the part carrying the lining is pivotally attached to the support plate and is secured in the operating position by stops. In this way, the device can be folded up after use and stored in a space-saving manner.
  • FIGS. 1, 2, 3 and 4 show a first embodiment, with FIG. 1 a top view and FIG. 2 a section along the line II-II of FIG. 1, FIG. 3 a view from below and FIG. 4 shows a section along the line IV-IV of FIG. 3, FIGS. 5, 6, 7 a further collapsible embodiment, the FIGS. 5 and 6 side views partly in section and FIG. 7 a section along the line VII - VII of FIG. 5, FIGS. 8 and 9 show a further embodiment, FIG. 8 showing a top view and FIG. 9 showing a section along the line IX-IX of FIG. 8, FIGS. 10 and 11 another embodiment with inflatable air cushions, wherein FIG. 10 shows a plan view and FIG. 11 shows a section along the line XI-XI of FIG. 10, and FIGS. 12 and 13 show an embodiment in which the lining is pressed against one another via pivoting levers, FIG. 12 being a Side view and Fig. 13 is a section along the line XIII-XIII of Fig. 12.
  • Fig. 1 denotes the base plate.
  • the base plate 1 has webs 2 in its central region, which, like the edges of the base plate, fly on the floor when the device is in operation.
  • This extension 3 is used to fix the elastic lining 4 of the mouth.
  • This elastic lining 4 has lamellae 5 which delimit the mouth 6.
  • the clear width a of the mouth is approximately 1/3 of the height of the mouth.
  • the elastic lining 4 surrounds with edges 7 and 8 the rigid parts of the base plate 1 or the upward extension and is fixed immovably in this way.
  • the axis 9 of the mouth 6 is inclined at an angle of approximately 75 ° to the floor plane 10.
  • a heel area of a boot is inserted into the mouth 6 and the device is held, for example, by depressing the base plate 1 with the other foot, the lamellae 5 of the elastic lining 4 press against the outer wall of the boot and it is simple and gentle Removal of the boot possible.
  • the webs 11 delimiting the base plate 1 merge into lateral wall areas 12 which, together with the projection 3 projecting upwards, form the holder surrounding the mouth 6.
  • the side wall regions 12 have openings 13, through which extensions 14 of the elastic lining reach and in this way ensure the anchoring of the lining.
