Definitions

  • This application relates to the dispensing of texture material and, more particularly, to systems and methods for dispensing small amounts of texture material to an un-textured portion of a target surface such that an applied texture pattern of the texture material substantially matches a preexisting texture pattern on a textured portion of the target surface.
  • the present invention generally relates to systems and methods for applying texture material to an interior surface such as a wall or ceiling.
  • buildings are typically constructed with a wood or metal framework.
  • drywaii material is attached to the framework.
  • at least one primer layer and at least one paint layer is applied to the surface of the drywall material to form a finished wall surface.
  • a bumpy or irregular texture layer is often formed on the drywall material after the drywall material has been primed and before it has been painted.
  • the appearance of the texture layer can take a number of patterns.
  • an "orange peel” texture pattern generally has the appearance of the surface of an orange and is formed by a spray of relatively small droplets of texture material applied in a dense, overlapping pattern.
  • a "splatter” texture pattern is formed by larger, more spaced out droplets of texture material.
  • a “knockdown" texture patter is formed by spraying texture material in larger droplets (like a "splatter" texture pattern) and then lightly working the surfaces of the applied droplets with a knife or scraper so that the highest points of the applied droplets are flattened.
  • a visible aggregate material such as polystyrene chips is added to the texture material to form what is commonly referred to as an "acoustic" or "popcorn” texture pattern.
  • the principles of the present invention are of primary
  • the texture layer is typically initially formed using a commercial texture sprayer.
  • Commercial texture sprayers typically comprise a spray gun, a hopper or other source of texture material, and a source of pressurized air.
  • the texture material is mixed with a stream of pressurized air within the texture gun, and the stream of pressurized air carries the texture material in droplets onto the target surface to be textured.
  • Commercial texture sprayers contain numerous points of
  • Aerosol systems that contain texture material and a propellant.
  • Aerosol systems typically include a container, a valve, and an actuator.
  • the container contains the texture material and propellant under pressure.
  • the valve is mounted to the container selectively to allow the pressurized propellant to force the texture material out of the container.
  • the actuator defines an outlet opening, and, when the actuator is depressed to place the valve in an open configuration, the pressurized propellant forces the texture material out of the outlet opening in a spray.
  • the spray typically approximates only one texture pattern, so it was difficult to match a variety of perhaps unknown preexisting texture patterns with original aerosol texturing products.
  • a relatively crude work around for using an aerosol texturing system to apply more than one texture pattern is to reduce the pressure of the propellant material within the container prior to operating the valve.
  • typical propellant materials exist in both a gas phase and in a liquid phase.
  • the propellant material in the liquid phase is mixed with the texture material, and the texture material in the gas state pressurizes the mixture of texture material and liquid propellant material.
  • a dip tube extends from the valve to the bottom of the container chamber to allow the propellant in the gas phase to force the texture material up from the bottom of the container chamber and out of the outlet opening when the valve is opened.
  • the container can be inverted, the valve opened, and the gas phase propellant material allowed to flow out of the aerosol system, reducing pressure within the container chamber.
  • the container is then returned upright and the valve operated again before the pressure of the propellant recovers such that the liquid contents are forced out in a coarser texture pattern.
  • This technique of adjusting the applied texture pattern result in only a limited number of texture patterns that are not highly repeatable and can drain the can of propellant before the texture material is fully dispensed.
  • a more refined method of varying the applied texture pattern created by aerosol texturing patterns involved adjusting the size of the outlet opening formed by the actuator structure.
  • the applied texture pattern could be varied by attaching one of a plurality of straws or tubes to the actuator member, where each tube defined an internal bore of a different diameter.
  • the straws or tubes were sized and dimensioned to obtain fine, medium, and coarse texture patterns appropriate for matching a relatively wide range of pre-existing texture patterns.
  • Additional structures such as caps and plates defining a plurality of openings each having a different cross-sectional area could be rotatably attached relative to the actuator member to change the size of the outlet opening. More recently, a class of products has been

  • the detent projections 1866 engage the socket portion 1824 around the socket windows 1852 to inhibit movement of the first adjustment member 1772 out of the socket chamber 1850 (and thus maintain the valve blade 1870 within the second portion of the actuator passageway 1834).
  • the socket windows 1852 are slightly oversized relative to the detent projections 1866.
  • the first adjustment member 1772 is thus capable of rotating within a limited range of movement relative to the socket portion 1824 about a socket axis A1s defined by the socket chamber 1850. If necessary, the first adjustment member 1772 may be removed from the actuator member 1754 by pushing the detent projections 1866 through socket windows 1852 such that the detent projections 1866 no longer engage the socket portion 1824.
  • the control assembly 1790 is formed when the outlet member 1756, first adjustment member 1772, seal member 1774, and second adjustment member 1782 are secured to the actuator member 1754 as described above. At this point, the control assembly 1790 is attached to the grip assembly 1758 to form the actuator assembly 1738. In particular, the pivot projections 1896 on the trigger member 1794 are inserted into the pivot openings 1888 of the grip housing 792 such that the trigger wall 1890 extends or is accessible through the trigger slot 1886. The trigger member 1794 rotates relative to the grip housing 1792 about a pivot axis A1 p.
  • the actuator assembly 1738 is then formed by displacing the control assembly 1790 into the space between the grip housing 1792 and the trigger member 1794 such that the link projections 1858 extend into the link openings 1894 in the link flanges 1892 of the trigger member 1794. Accordingly, as the trigger member 1794 pivots relative to the grip housing 1792, the link flanges 892 around the link openings 1894 engage the link projections 1858 to displace the control assembly 1790 relative to the grip assembly 1758.
  • control assembly 1790 is capable of linear, in addition to (at this point) pivoting, movement relative to the grip assembly 1758, as will be described in further detail below.
  • the actuator assembly 1738 is then attached to the container assembly 1730 by inserting the inlet portion 1820 of the actuator member 1754 through the valve seat 1764 such that the inlet portion 1820 engages the valve member 1762 as shown in Figure 68. At the same time, the perimeter edge 1880a of the grip housing 1792 frictionally engages the container assembly 1730.
  • the grip housing 1792 supports the trigger member 1794 for pivoting movement relative to the container assembly 1730, and the control assembly 1790 is supported by the trigger member 1794 and the valve seat 1764 for linear movement relative to the container assembly 1730.
  • the protection wall 1882 extends over the top of the actuator assembly 1738 to prevent inadvertent contact with the actuator assembly 738 that might place the valve system 1760 in the open configuration.
  • the example second actuator member 1782 operates to deform the outlet member 1756 and alter a cross-sectional area of the conduit outlet or outlet opening 1746 as generally described in U.S. Patent Nos. 6,116,473 and 7,845,532, which are incorporated herein by reference, and thus will not be described or depicted herein in detail.
  • the Applicant notes that other systems and methods for altering the cross-sectional area of a conduit outlet or outlet opening may be used in place of the resiliently deformable outlet member 756, second adjustment member 782, and fingers 842 described herein.
  • 7,500,621 which is incorporated herein by reference, discloses a number of examples of systems and methods for adjusting the outlet opening of an aerosol system in the context of dispensing texture material.
  • Systems and methods for altering a cross-sectional area of an outlet orifice include the use of multiple straws, each having a different internal diameter, the use of a rotating plate in which holes are formed, the use of a rotating cap in which holes are formed, the use of a deformable tube that is pinched down from an original configuration, and/or the use of a deformable tube that is pulled open from an original configuration.
  • Figures 74 and 74A illustrate the first adjustment system 1770 in an intermediate opening configuration.
  • Figures 75 and 75A illustrate the first adjustment system 1770 in a minimum opening configuration.
  • the valve blade 870 thus extends into the actuator passageway 1834 such that the valve blade 1870 is capable of restricting flow of fluid flowing through the actuator passageway 1834.
  • the amount of restriction depends on the angular position of the valve blade 870 with respect to at least one of the transition surface 1878, an outlet axis A o defined by the actuator passageway 1834, and/or the socket axis A1s-
  • the angular position of the valve blade 1870 can be altered by displacing the handle portion 1860 of the first adjustment member 1772 relative to the actuator member 1754.
  • the use of the optional locator projection 1854 and locator arm 1869 allows the first adjustment member 1772 to be locked into any one of a plurality (two or more, three in this case) of positions relative to the actuator member 1754.
  • the size and shape of the socket windows 1852 in relation to the size and shape of the detent projections 1866 may determine the limits of rotation of the first adjustment member 1772 relative to the actuator member 1754 to a predetermined adjustment range.
  • the bottom surface 1872 of the valve blade 1870 is configured to follow the curvature of the actuator passageway 834 where the adjustment opening 1878 intersects this passageway 1834.
  • the example valve slot 1872 is configured to cooperate with the transition surface 1878 to define a plurality of discrete cross-sectional dimensions of the actuator passageway 1834.
  • the first adjustment member 772 is capable of being rotated such that the valve blade 1870 rotates between a fully open position (Figure 73A), an intermediate position (Figure 74A, and a terminal position (Figure 75A).
  • Figure 73A shows that the fully open position leaves the actuator passageway unrestricted (0% blocked).
  • Figure 74A shows that the intermediate position reduces the size of the actuator
  • Figure 74A shows that the terminal position reduces the size of the actuator passageway by a second predetermined amount determined substantially by the dimensions of the notch 1876 in the valve blade 1870.
  • a cross- sectional area of the actuator passageway 1834 adjacent to the transition surface becomes smaller but is never fully blocked.
  • Each of the three positions allowed by the first adjustment member 1772 are predetermined or tuned for a particular aerosol dispensing system.
  • the system variable controlled by this first adjustment system 1770 may be referred to as percentage closure of the cross-sectional area of the actuator passageway 834. Relative to the cross-sectional area of the unobstructed actuator passageway 834, the fully open position of the valve blade 1870 will block a first
  • predetermined percentage e.g., 0%
  • predetermined adjustment range allowed by the first adjustment member allows the valve blade 1870 to rotate from the fully open position to the terminal position in which a second predetermined percentage of this cross-sectional area the unobstructed actuator passageway 1834 is blocked. In the intermediate position a third predetermined percentage of this cross-sectional area the unobstructed actuator passageway 1834 is blocked.
  • Table O represents example ranges and dimensions for constructing a physical embodiment of a flow adjustment system that may be used as the example first flow adjustment system 1770:
  • the actual cross-sectional area of the unobstructed passageway second portion 1838 will be determined by such factors as the characteristics of the stored material 1734 (e.g., composition, viscosity) and of the propellant material (e.g., composition, percentage by weight used), and the nature and physical shapes of the desired texture patterns to be obtained using the dispensing system 1720.
