Description
24 1 8880
DESCRIPTION
The present invention relates to a manually operated cutting machine with disc blade, in particular to be used for floorings made of cement, bitumen and the like.
It is know that manually operated cutting machines with disc blade commonly used to cut floorings made of bitumen or cement conglomerates, for example in order to create expansion joints or delimitation of excavations, consist essentially of a hand-cart pushed by an operator, onto which a motor is mounted. The motor, generally by means of a transmission belt, moves a diamond disc intended to make the cut in the true sense.
Manually operated cutting machines currently available on the market suffer from various inconveniences, among which directional instability or reduced maneuverability or reduced depth of cut or excessive vibrations.
The main objective of the present invention is to propose a manually operated cutting machine capable of eliminating said inconveniences.
This result has been achieved, according to the present invention, by adopting the idea of creating a machine having the characteristics disclosed in claim 1. Further characteristics of the present invention are dealt with in the dependent claims.
A machine according to the present invention eliminates said inconveniences, being directionally stable, easily maneuverable, that is ergonomically efficient, light, sturdy and sufficiently rigid. Moreover, a machine according to the present invention provides great cutting depth made by the disc blade, is relatively easy to make, cost-effective, reliable even after extensive use and is substantially free from vibrations detrimental both to the operator and to the overall endurance of the structural components of the machine.
These and other advantages and characteristics of the invention will be best understood by anyone skilled in the art from a reading of the following description in conjunction with the attached drawings given as a practical exemplification of the invention, but not to be considered in a limitative sense, wherein: Figs. 1-3 show, respectively, a frontal view, a lateral view and a plan view from above of the supporting structure of a cutting machine according to the invention; Fig. 4 is an analogous view to that in Fig. 2, where, in addition to said structure, the plate with the seat for the disc-bearing shaft, the motor-bearing plate, and the mechanism regulating cutting depth are visible; Fig. 5 is an analogous view to that in Fig. 2 and Fig. 4, where the motor group and the diamond disc with its relative protection case are visible.
Reduced to its basic structure and with reference being made to the figures in the attached drawings, a cutting machine according to the present invention is of the kind comprising a cart-like structure (1), with two back wheels (2) and two front wheels (3) carrying a motor (4) to which a diamond disc is connected (5). The latter is set on a side of the structure (1) and is connected to an end of a corresponding shaft (6) which is oriented parallel to the rotation axes of the wheels (2, 3), so that the disc (5) results oriented parallel to the front and back - 2 wheels of the structure. For example, said motor (4) may be an internalcombustion engine fed by the fuel contained in a tank (7) carried by the same structure (1). The shaft (6) of the disc (5) may be connected to the motor (4) by means of a transmission belt, of the kind already known to the technicians of the field and not visible in the figures in the attached drawings, engaging the extremity of the shaft (6) opposite to the end to which the disc (5) is attached. The quota of the disc (5), that is the depth of cut, is adjustable by means of a regulation device comprising a wheel (8) which leads to the lifting or lowering of the disc by means of its clockwise or counterclockwise rotation.
Advantageously, said structure (l) is a closed cage structure, that is a structure comprising a lower base, an upper annular frame and a plurality of standards which connect said lower base to said upper frame. Said cage delimits a space to set the motor group (4) and constitutes a support element for the axes of the wheels (2, 3), for the motor (4) and for the shaft (6) of the disc (5).
In more detail, with reference being made to the example in the figures in the attached drawings, the lower base of said structure (1) comprises two concave metal plates (20, 30), having the concavity facing downwards and respectively supporting the axes of the back wheels (2) and of the front wheels (3). A metal tubular standard (31) is welded to the front plate (30) in a central position. Two metal tubular standards (21) are welded to the back plate (20) on opposite sides of the plane of longitudinal symmetry (S) of the structure. Each one of the rear standards (21) is connected to the front plate (30) by means of a corresponding arm (23). The two arms (23) delimit the bottom-lateral portion ofthe structure (1). - 3
Each one of said arms (23) is made of a metal tubular element having a portion (231) which develops orthogonally to said plane of symmetry (S) and which departs from the respective standard (21), having a portion (232) parallel to said plane, and having a portion (233) connecting it to the front plate (30), converging towards the plane (S). The rear standards (31) are connected to the front standard (21) by means of an annular element made of tubular metal material (32) set at a preset distance from said arms (23) and welded to the three standards at hand.
A disc-bearing plate (9) and a motor-bearing plate (10) are mounted onto the structure (1).
The back side of the disc-bearing plate (9) is hinged to the axis (11) of the back wheels (2) and is provided, in correspondence of its front side, that is the side facing the front wheels (3), with a tubular element (12) containing inside the shaft (6) of the disc (5). The length of said plate (9) is such that the tubular element (12), and with it the shaft (6), results inside the axes of the wheels (2, 3), that is within the space delimited altogether by the structure (1).
Preferably, said tubular element (12), hence the shaft (6), is positioned closer to the front wheels (3) than to the back wheels (2).
En end of the axis (13) is connected to the disc-bearing plate (9), said axis (13) being connected to the wheel (8) by means of a common wormscrew transmission: the clockwise or counter-clockwise rotation of the wheel (a) leads to the corresponding longitudinal traverse of the axis (13) and, consequently, to the rotation of the plate (9) around the axis (11) of the back wheels (2), with the lowering or lifting of the disc (5) in relation to the plane of the surface to be - 4 The motor-bearing plate (10) is positioned above the disc-bearing plate (9). In more detail, the back side of the motor-bearing plate (10) is hinged to the disc- bearing plate (9). The axis of the hinge in this connection, represented by the numeric reference 14 in Fig. 4 and Fig. 5, is parallel to the axes of the wheels (2, 3) and of said shaft (6), that is orthogonal to the plane of symmetry (S) of the structure ( 1).
Moreover, advantageously, said plates (9) and (10) are connected to each other, in correspondence of the respective front sides, by means of dampers ( 15).
Two tubular extensions ( 16) for maneuvering to be held by the operator responsible for the directing the machine are inserted onto the two tubular rear standards.
Advantageously, each said extension (16) exhibits a first portion (161) coaxial with the respective standard (21) and a second portion (162) oriented upwards and forwards, that is towards the front side ofthe structure (1).
During the lowering/lifting of the disc (5), the structure remains steady, that is it does not go either up or down. Analogously, the handles (161; 162) are not tilted in any way.
The term "plate" used in the present description to identify the elements (9) and (10) refers to a structural element with a predominant bi-dimensional development.
Practically, the construction details may vary in any equivalent way as far as the shape, dimension, disposition of elements and materials used are concerned, - 5 without nevertheless departing from the scope of the adopted solution idea and, thereby, remaining within the limits of protection granted to the present patent for industrial invention. - 6
