Object of the Invention
[0001] The object of the present invention patent is to present a novel air-powered manual
vibrating screed which, by means of a profile internally incorporating a series of
pneumatic vibrators, interconnected to one another by means of flexible tubes through
which the compressed air circulates, which compressed air enters through the connection
coupling to an air compressor, allows smoothing the plaster and the mortar in walls
and ceilings in a very effective manner by the action of the vibration of the material
by means of said profile.
[0002] This novel air-powered manual vibrating screed has a particular application in the
field of construction in which, due to circumstances, it is necessary to have an air-powered
manual vibrating screed, to improve the efficacy in the application of the plaster
and mortar paste in plastering walls and ceilings.
Background of the Invention
[0003] To date, there have been different types of screeds which are used for screeding
plaster walls or surfaces, which usually travel on previously calibrated guides fixed
to the surface to be smoothed, or which moves over the surface to be smoothed with
the arms by means of the use of a simple screed.
[0004] Currently, plaster and mortar paste is applied manually, projecting the material
on walls and ceilings to be subsequently leveled and distributed as homogenously as
possible by means of manual tool, such as a trowel or a manual screed based on several
passes until the desired effect is achieved.
[0005] In order for these elements to be suitably distributed, an amount of water must be
added to fluidize them and to make their distribution easier.
[0006] Given the scarcity of water in the environment, it is very necessary to try to reduce
the use of this element when carrying out industrial processes such as the process
of plaster coatings on walls and ceilings.
Description of the Invention
[0007] In order to palliate or, where appropriate, eliminate the aforementioned problems,
this novel air-powered manual vibrating screed is presented which basically consists
of a profile internally incorporating a series of pneumatic vibrators interconnected
to one another by means of flexible tubes through which the compressed air circulates,
which compressed air enters through the connection coupling to an air compressor;
arranged next to said connection coupling to an air compressor there is an on/off
valve to regulate the pressure of the air circulating through the flexible tubes.
[0008] Since the pressure of the air feeding the pneumatic vibrators can be adjusted, the
vibration force of the profile can be regulated according to the needs which are required.
[0009] It requires less physical effort by the person screeding a surface since the number
of passes over said surface is reduced by means of the vibration, increasing the effectiveness
of the person's effort and reducing the time used for doing so because since it can
be leveled and distributed more quickly and homogeneously, the time necessary for
the application is reduced, thereby reducing costs with regard to the manual labor
to be used in the process and the consumption of water is reduced, which results in
a second economic savings and in a measure that favors the environment.
[0010] The main advantage provided by the present invention is the improvement of the plastering
process with regard to the final finish achieved and the time of performance used.
Description of the Drawings
[0011] To complement the description being made and for the purpose of aiding to better
understand the features of the invention, a figure is attached to the present specification
as an integral part thereof in which the following is depicted with an illustrative
and non-limiting character:
- Figure 1: Plan view of the air-powered manual vibrating screed, object of the present
invention patent.
Preferred Embodiment of the Invention
[0012] As can be observed in the attached figure, the air-powered manual vibrating screed
object of the present invention patent consists of a profile (1) internally incorporating
a series of pneumatic vibrators (2), interconnected to one another by means of the
flexible tubes (3) through which the compressed air circulates, which compressed air
enters through the connection coupling to an air compressor (4); arranged next to
said connection coupling to an air compressor (4) there is an on/off valve (5) regulating
the pressure of the air circulating through the flexible tubes (3).
[0013] The operation is as follows: after projecting the plaster or mortar paste on a surface,
the connection coupling to an air compressor (4) is coupled to any air compressor
which will supply a compressed air flow, which will be regulated by means of the on/off
valve (5), the compressed air will circulate through the flexible tubes (3) until
reaching the pneumatic vibrators (2), which will cause a vibration in the entire profile
(1), making the job of screeding easier when smoothing walls and ceilings.
[0014] Having sufficiently described the nature of the present invention as well as a manner
of carrying it out to practice, it is only necessary to add that said invention can
undergo certain variations in the shape and the materials provided that said alterations
do not substantially vary the features claimed below.

coupling to an air compressor (4); arranged next to said connection coupling to an
air compressor (4) there is an on/off valve (5) regulating the pressure of the air
circulating through the flexible tubes (3).
