BACKGROUND OF THE INVENTION
[0001] The present invention relates to an improved device for mixing paints in paint vessels
and the like.
[0002] 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.
[0003] 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
[0004] 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.
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] Said paint vessel supporting pin is rotatively driven by friction engaging it with
an abutment friction surface.

[0010] Further characteristics and advantages of the invention will become more apparent

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] The paint vessel clamping means 20 comprise a cylindric body 21, in which a paint
vessel 22 can be removably engaged.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] Thus, with the disclosed arrangement, by operating the motor 5, the pulley 4 is caused
to turn.
[0020] Accordingly, the paint vessel will be rotated about a horizontal axis by said angular
arm 10.
[0021] 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.
[0022] 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.
[0023] From the above disclosure it should be apparent that the invention fully achieves
the intended aim and objects.
[0024] 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.
[0025] 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.
