Definitions
- the invention relates to a device for processing shoes, in particular for cutting soles and heels.
- shoes that are individually adapted to the particular anatomical particularities are often required as a therapeutic measure.
- Such orthopedic shoes have to be provided with heel or heel increases, for example, to compensate for bones of different lengths or joint displacements.
- Orthopedic shoes are either completely handcrafted by the orthopedic shoemaker if the anatomical peculiarities of the foot require it, or commercially available shoes are adapted through a revision.
- sole or heel increases are subsequently introduced, which may also be carried out as an asymmetrical inner or outer edge increase, taking into account the individual characteristics.
- the invention proposes a device with a base plate on which a clamping device for a shoe is attached and with a motor-driven cutting device which is movably mounted on the base plate in guides, the tread of a shoe clamped on the clamping device seen from the base plate is directed outwards and the cutting tool of the cutting device can be guided longitudinally through the sole or the heel of the shoe.
- the device according to the invention preferably has a horizontal base plate, on which a clamping device for a shoe is mounted, projecting upwards.
- the shoe can be placed on this with the sole side facing upwards, that is to say the tread, and can be fixed in this position by means of expandable tensioning elements or the like.
- the motor-driven cutting device the cutting tool of which can be, for example, a saw blade, band or wire, a knife blade or a cutting wire, optionally also a heated cutting wire, is aligned with its cutting tool transversely to the longitudinal extent of the shoe clamped on the clamping device.
- the free cutting width of the cutting tool is designed to be somewhat wider than the maximum width of a tread.
- the cutting device is movably mounted in the guides on the base plate in such a way that the cutting tool can be moved lengthways through the sole or the heel of the shoe at the level of the clamping device.
- the shoemaker has the possibility for the first time to cut off the tread or parts thereof with a clean cut.
- the motorized cutting device for example a fine saw, creates a smooth, regular cutting surface.
- the cutting device on the base plate relative to the clamping device ensures that the desired cut can be carried out exactly with relatively little effort. This significantly reduces the amount of work and time.
- Another advantage is that the cut surfaces are relatively smooth from the outset and require little or no reworking before gluing.
- the guides are expediently designed such that the cutting tool is guided parallel to the base plate in the longitudinal direction. This makes it possible to just cut through the sole and heel parallel to the tread. A straight or wedge-shaped elevation is glued between the cut surfaces.
- Preferred developments of the device according to the invention provide that the cutting tool is also guided perpendicular to the base plate and / or can be tilted with respect to the latter. Such configurations also allow oblique cuts to be carried out in all required inclinations, while the aforementioned advantages are retained.
- the cutting device is a band saw. This has a high cutting performance, so that tough and resistant materials such as rubber and the like can be easily cut.
- the use of a fine saw blade results in a smooth and even cutting surface that requires practically no reworking before gluing.
- a preferred embodiment provides that the band saw is arranged in a portal-like manner at a distance from the base plate between two vertical supports which are slidably mounted in the longitudinal direction on the base plate, the saw plate facing the base plate extending transversely to the direction of displacement.
- the vertical supports run, for example, in roller rails attached to the side of the base plate. Due to the open design, the clamping device for clamping and removing shoes is particularly easily accessible when the cutting device is pushed forwards or backwards.
- handles preferably a pair of handles
- the shoemaker can grip and guide the band saw on both sides using these handles.
- he pulls the band saw comfortably towards the body using the handles in the longitudinal direction. In the meantime, he can view the cut at any time and correct it if necessary.
- any cuts can be made parallel to the base plate with parallel adjustment; with different height settings on the two vertical beams, the tread becomes corresponding cut at an angle. These movements can also be easily followed by the shoemaker on the handles.
- band saw is rotatably mounted on the vertical supports with respect to an axis of rotation lying parallel to the saw blade. With this measure, cuts sloping in the longitudinal direction can also be carried out comfortably. Handling is in turn made easier by the handles.
- a switch for driving the band saw is arranged on the handles.
- two safety switches arranged in series on each handle it is achieved that it is impossible to start the band saw with one hand and to reach into the running saw blade with the other hand. In this way, injuries are almost impossible.
- a shoe is held particularly securely on the clamping device if it is designed in the manner of a cross-expandable last.
- An advantageous development of the invention further provides that the guides can be locked in a preset position.
- the handling and the reproducibility of the cuts is made even easier by, for example, the distance relative to the base plate and the tilting of the cutting tool being fixed so that the cutting device only has to be moved in the longitudinal direction to cut the sole or heel.
- Figure 1 is a top view of a device according to the invention.
- Fig. 2 is a front view of the
- a device according to the invention is shown in a view from above and provided with the reference number 1 as a whole.
- a horizontally arranged base plate 2 on which - shown in dashed lines - a clamping device 3 for a shoe 4 is attached. This is so wide that you can see your tread in this view.
- a motor-driven band saw 5 is provided, the saw band 6 of which is shown in dashed lines and extends transversely to the longitudinal extension of the base plate 2.
- the band saw 5 is arranged rotatably about an axis lying in the direction of the saw band 6 between two vertical supports 7. These are mounted by means of rollers 8, which together with guide rails 9 running laterally on the base plate in the longitudinal direction, are longitudinally displaceable relative to the base plate 2 and thus relative to the clamping device 3.
- FIG. 2 shows the device 1 according to FIG. 1 in a longitudinal view from the front. This shows the portal-like arrangement of the band saw 5 at a distance from the base plate 2 particularly clearly. From this it can be seen from this illustration how the sole or heel 11 of the shoe 4 can be cut horizontally, ie parallel to the base plate 2, with the saw band 6.
- This illustration further shows that the band saw 5 is slidably mounted on the vertical supports 7 perpendicular to the base plate 2, which is indicated by arrows.
- the saw band 6 can be adjusted obliquely relative to the base plate 2, so that oblique cuts, for example to increase the side edge of a sole 11, can also be set.
- the handling of the device 1 according to the invention is very simple: a shoe 4 is clamped onto the clamping device 3 in such a way that the sole 11 is arranged parallel to the base plate 2 in an upward direction.
- the band saw 5 is gripped on the handles 1 0 and set in the vertical supports 7 perpendicular to the base plate 2 so that the saw band 6 runs according to the desired cut relative to the sole or heel 1 1 of the shoe 4.
- the shoemaker then only needs to move the band saw 5 on the handles 1 0 in the longitudinal direction, which is easy to carry out thanks to the roller guide with the rollers 8 and the guide rails 9.
- the sole or heel 1 1 is cut cleanly by the saw band 6 in the longitudinal direction. In this way, the device according to the invention saves time and laborious manual work.
- the cut surface is clean and requires at most a little post-processing, so that the separated pieces of the tread can be reused.
