Abstract

The present invention relates to an improved device for mixing paints in paint vessels and the like, comprising a holding construction (1), inside which is rotatably supported a horizontal pin (3), in turn supporting a pulley (4) coupled to driving means (6) for turning the pulley (4) about the horizontal pin.

An angular arm (10) coupled to the pulley (4) and rotatably supporting a vertical pin (11) to which is coupled a paint vessel supporting plate (12) is moreover provided.

The paint vessel supporting plate (12) is caused to turn by friction engaging it with an abutment surface.

Description

BACKGROUND OF THE INVENTION

The present invention relates to an improved device for mixing paints in paint vessels and the like.

As is known, for properly mixing paints held in paint vessels or cans are conventionally used rather complex apparatus which, practically, provide vibrations suitable to mix the pain components.

The prior apparatus, however, have a comparatively high cost and size, due to the construction principle used therein, and, for this reason, said apparatus have not been broadly practically used.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks, by providing an improved device for mixing paints in paint vessels and the like, allowing the paint to be optimally mixed, by properly causing the paint vessels to be rotatively and revolutionally driven.

Within the scope of the above mentioned aim, a main object of the present invention is to provide such a paint mixing device which is very simple construction wise and which, accordingly, is susceptible to be broadly used by paint users.

Another object of the present invention is to provide such a paint mixing device which is very reliable and safe in operation, can be easily made starting from easily commercially available elements and materials, and which, moreover, is very competitive from a mere economic standpoint.

According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by an improved device for mixing paints in paint vessels and the like, characterized in that said device comprises a holding construction, inside of which is rotatably supported a horizontal pin in turn supporting a pulley coupled to driving means adapted to turn said pulley about said horizontal pin.

A rotary angular arm coupled to said pulley and supporting a vertical pin to which is coupled a paint vessel supporting plate is moreover provided.

Said paint vessel supporting pin is rotatively driven by friction engaging it with an abutment friction surface.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures, the improved device for mixing paints in paint vessels and the like, according to the present invention, comprises a holding construction 1, inside of which is arranged a supporting bracket 2, extending for a vertical length and ending with a horizontal pin 3, which is rotatably supported.

At one end of said horizontal pin 3 is coupled a pulley 4, on which a pulley belt 5 is entrained which is driven by a motor 6 so as to cause said pulley to turn about an axis defined by said horizontal pin 3.

At the other end of the pin 3, which is rotatively rigid with said pulley 4, is coupled an angular arm 10 which, at the end portion thereof not coupled to said pulley, is provided with a vertical pin 11, which is also rotatably supported, and, accordingly, being perpendicular to the horizontal pin 3.

To the pin 11 is rigidly coupled a plate 12, provided with means for clamping thereon a paint vessel, said clamping means being generally indicated by the reference number 20.

The paint vessel clamping means 20 comprise a cylindric body 21, in which a paint vessel 22 can be removably engaged.

On the inner bottom of the cylindric body 21, an urging spring 23 is provided, said spring operating on a plate 24 provided for supporting the bottom portion of the paint vessel 22 to cause it to be upwardly pushed.

In order to restrain the paint vessel, is provided a cover 30 having a substantially octagonal configuration and supporting a handle 31, which can turn with respect to said cover and being coupled, on the surface thereof opposite to the cover, to an elongated small plate 32 projecting from said cover and ending with locking elements 33 which can be rotatively introduced into pairs of opposite slots 34 formed on the cylindric body 21.

In order to turn said plate 12, friction turning means are provided, which are advantageously constituted by a rubber ring 30, coupled to said plate and friction engaging with an abutment surface 31 defining a side wall of the holding body 1.

Thus, with the disclosed arrangement, by operating the motor 5, the pulley 4 is caused to turn.

Accordingly, the paint vessel will be rotated about a horizontal axis by said angular arm 10.

The friction engagement provided by said rubber ring 30 will cause the plate 12 to turn about an axis perpendicular to the above mentioned rotary axis, thereby the paint vessel will be subjected to a double rotation, about two mutually perpendicular axes.

In this manner, is obtained a combination of rotary and revolution movements, providing a perfect mixing of the paint material held in its respective paint vessel.

From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.

In particular, the fact is to be pointed out that a very simple mixing device has been provided which, by a single motor, can provide a rotary movement about two mutually perpendicular axes, without requiring complex gear couplings.

In practicing the invention, the used materials, provided that they are compatible to the intended use, as well as the contingent size and shapes, can be any, depending on requirements.
