Item »CUTTER for FLOOR PADS

The invention relates to a cutting material that is resistant to cutting, such as linoleum, linoleum-like and sttfagula-like plastics, tappe, rubber and Astest, suitable device "

The cutting device, which is the subject of this invention, is used in particular to Cutting and separating floor and wall coverings from the above Materials directly on the shelf without the possibility of this not to damage it, even if it is made of much softer materials consists.

Furthermore, relevant craftsmen can also use so-called "cutting tables" and dealers such as Heimbastier cut such material to size without damaging the "table top" »or with a hard surface must be protected, as was previously the case with conventional cutting Measers, which by the way become blunt during this work, happens In all previously known, hand-mechanical son oath devices in knife form, existed the impossibility of an easy cut on the immediate contact surface without damaging the underbody. Furthermore, never was an economically justifiable one Shaft stability of the blade guaranteed.

In addition to the other disadvantages, which are listed in detail, the costs of maintaining the operational readiness of the previously known devices, Izv, durtir Kl irigMn, represent several times that which is expediently sufficient for the subject matter of this invention.

Those listed in the drawing attachment in terms of cost and technology and previously known devices for the previously mentioned purpose are the following:

a'J types 1 and 11:

The ones that quickly become blunt due to the high mechanical stress Blade edges of these types can no longer be resharpened from an economic point of view

t ·) Resharpening is only possible after removing the screwed, bolted or welded pin of the guide pin (DOEIi), which leads through a perforation in the blade on special machines possible·

The dismantling of the old dome and the attachment of a new mandrel creates a constant risk of breakage for the blade, because the attachment of the mandrel in the perforation of the very hardened blade and the resulting material stresses often lead to cracks or Fractures in the blade near the hole

Such a repair by means of assembly, according to the risk of breakage plus shipping costs ₍ is completely uneconomical, as it is more expensive than buying a new blade
Types 1 and 11:

Both types shown are in use in handling a constant risk of breakage and the risk of deviation from the cutting line. 1.)

Types X and 11 J

With both types shown, arise, especially when cutting

of linoleum linoleum-like materials, cardboard-like and stragula-like, in particular materials coated with pilebag or anti-slip coverings, at the moment when the blade edges become even slightly blunt will start between the cutting edge and the material to be cut, namely in front of the edge of the blade, material build-up as a result of their very compact degeneration of a trap-shaped type, prevent any further cutting

If the previous cutting handling is continued, it will tear cutting linoleum ■ - stangula-like material, especially those with the Fila or Hutsch coverings mentioned above, but mainly cardboard or similar properties Material "shredded" apart ·

The consequence of this is that not only does the sectional image become unclean, but also at the same time leads to the fact that the originally planned separation is not continued can be, at least not in the previously planned direction

The stagnation points, (according to the figure "BEKANNTE ITOMSCHNEIDeERÄTE" = ⁿ St "on the cutting * good =» "Gr".) Turn yellow only at the places shown on the figure with an arrow mark (-St- ·) »

These typical accumulations of cutting material are primarily caused by Blades that have become slightly blunt, but would last for a long time nevertheless does not occur when the angular positions of the cutting surfaces to The product to be cut would be optimal ^ as it is one of the main features of the invention

k ·) Every right-angled or approximately right-angled position of the cutting edge at any point in relation to the material to be cut is still critical, even when cutting with extremely sharp blades, since the blade cutting edge is thus deprived of any sliding moment.

This is the case in particular with the hooked blade (see illustration: "BEXAMTE IMESJSCHNEIDGERA'TE" Type 1.) at the apex of the cutting edge rounding. It would therefore be completely absurd _t such a blade attached by means of a. To provide a "sliding plate" to protect the bottom floor, and for the "intended purpose" of the above statements Carry out a clean cut with relatively sharp cutting edges and still open material accumulation · Both features are not given in the above-mentioned ÜVp "hooked blade" (type * 1. see illustration)! 1098397000 6

Contrary to the subject of this invention, this device is based on the idea of perfecting the conventional handles of the Vy jj _: partially standardized or standardized linoleum knives, which are usually equipped with trapezoidal blades of wide format or hook blades, with another type of blade.

Constructions were used for this (see Fig. »Type» III.) Namely blades, characterized in that PLATTEH at right angles or at an acute angle to the Cutting edge of a normal trapezoidal blade are mainly attached by soldering The PLATE should be guided along the sub-floor in the pulling direction to protect the sub-floor during the cutting of linoleum-like coverings. Economically as well as technically, such blades have proven to be unsuitable proven *

The very elaborate blade can only be used with certain items of sight, under no circumstances but with cardboard or even corrugated cardboard, they serve their purpose very short-lived ^ then 1 ·) causes the plate to be attached to the sharpened blade in all of them known fastening methods a blunt cutting piece directly ■: between the plate and the adjacent cutting edge as a result of welding spots, soldering points or overmolded parts for plastic or Angufimetal The cutting edge can no longer be ground sharply enough at these points "earth.

2) With this construction, only this particularly critical point of the cutting edge is always used as a result of the material flow in the direction of

This is more important to umeo because the blade is always in a critical position Position of the cutting edge in relation to the product to be cut "- acute angled to vertical ··" must be, a circumstance »which according to the explanations (S» -3-, Funct 1V) inevitably leads to material build-up * jA more favorable angular position on the other hand but the use of conventional snowshoeing grips.

As Figure 3 of the application drawing shows, the inventor also a solution to the ideal cutting problem using conventional, partially standardized handles of the relevant type (called linoleum knife handle), by attaching a notch and perforations fitting blade, which due to a different angular position of the cutting edge to the material to be cut and to the PLAIÜE (Pl), none has critical congestion points (St), searched.

The possibility of a useful function of the blade is thereby given and shown.

The nature of the commonly used, conventional, partly standardized notebooks or handles, their function in common with the blade in work use represent a main feature of the invention, leaving one only limited in its properties and recognize inappropriate usability of the above construction in practice.

This is because such handles or handles of the known linoleum knife type, solely for the purpose of an effect as Pull handles under pressure when cutting against the worker are constructed.

According to FIG. 3 of the application drawing, the inventor manufactured on a trial basis a device of the type mentioned above, in which the blade edge with the same position of the blade, handle and "Plate" only sharpened on the opposite side of the blade,

He achieved that this construction of linoleum and similar materials on a plate or a sub-floor (ÜB) essentially easier and more permanent cut and there were no stagnation points (St) between the cutting edge, plate, handle and material to be cut, because the device now has an obtuse angle between the blade edge and PLASTE acted on the material to be cut.

It turned out, however, that this device, in spite of all its advantages compared to the previously known devices, but for many necessary areas of application of such a device when cutting and "Laying" of floor coverings, was not usable.

As one of the most important reasons for the breadth of use and less handiness of this experimental device turned out to be

109839/0006

Characteristic feature of the position of the blade edge together with the plate towards the inclination of the grip.

In this position, the inevitable property of the one described above Trying is, makes 1.) the handling of the handle with any cutting method exhausting, uncomfortable and unfamiliar, because it runs contrary to the natural cutting habits When cutting with conventional knives, namely cutting under tension and pressure, 2.) the end of the handle facing away from the worker disturbs most work activities of a relevant nature and makes them impossible in essential processes. In the often necessary Application, namely when the floor covering is cut at its edge, directly on a wall facing it at right angles must be, in order to be separated further from the cutting point on the subfloor, this inevitably prevented the end of the handle facing away from the cut edge, at an angle against the wall, any bleed.

The task of the invention resulted from the above, namely the Creation of so-called sliding knives »i.e. knife blades with cutting edge and support plate and subsequent handle, which under perform their task under optimal conditions and conventional handling.

DESCRIPTION OF THE OVERALL FEATURES OF THE EEFIKDÜSG:

Both device types according to the registration drawing (liguren 4 and 5) are like this designed so that they have the following main features necessary for optimal protection in the sense of the purpose described above:

1.) line with one or more cover plates (PL) to protect against cutting damage even on soft contact surfaces (UB) below the blade cutting edge and especially replaceable blade, the cutting edge (FIGUBEN 4 and 5 = S) for the purpose of achieving a jam-free sliding cut compared to the one to be cut, material to be cut, it is advisable to have an obtuse angle of 100 to 130 degrees between the support plate (Pl) and the cutting edge (S), since the stagnation points indicated with (SI) in the drawings can only be avoided by means of an obtuse angle between the cutting edge and the support plate.

109839/0008

2.) Achievement of the conventional and only "comfortable" type of cut, namely the Z0SSCH8I33! Of the device with the end of the staple in the direction of the operator's body, with the working hand resting on a generally inclined device with a grip on the handle äesaelissia with Sen Singern ·
