Description of the Invention: [Technical Field of the Invention] The present invention relates to a mask for defining the shape of a liquid to be sprayed onto a surface. It is primarily, but not exclusively, the equipment used to spray lines onto surfaces such as roads, parking lots, factory and gym floors, playgrounds and play areas, playgrounds and sports fields. More particularly, the present invention relates to a line drawing apparatus and components thereof, including a spray operating device, and an adjustment configuration for stability and line width. [Prior Art] It is known that a spray or twisting device comprises at least a spray of a conventional twisting liquid which lacks a tilting tube and is reversely mounted on a roller, so that when the spray nozzle is touched open, A line will be formed by spraying the rifling liquid down on the sliding surface of the device. One problem with this device is that the spray line may lack clear edge definition due to the pattern and distribution of the liquid spray. Traditionally, some forms of masking or shielding have been utilized to limit the lateral spray of the drawn liquid to control the above problems. However, this mask or shield accumulates a "drop" of the spray line liquid, which in turn can cause the clarity of the spray line to be lost and outside the line. Another problem associated with this device is the lack of lateral stability. The simplest twisting device consists of at least one pair of wheels and sprays the twisting liquid between them. The wheel train sets the line width and is therefore very close and lacks lateral stability; it allows the slide to "shake" as it slides, resulting in a curved line. This 6 200900557 one solution to the problem is to provide a fixed or additional rear stabilizer wheel; however, this may limit the proximity to a wall or similar obstacle when spraying a line. A further problem is that when the spray is operated, the nozzle is typically positioned in a mount and then the spray can is forced downwardly against the seat to open a spring-type nozzle valve. This may cause accidental discharge of the spray even when a small downward force is applied to the spray can inadvertently. The prior art document GB-A-1456411 (Rocol Limited) discloses a twist line applicator comprising at least one pressurized spray dispenser of a line drawing liquid for spraying down the wheel of a two-wheel slide, and a pair of shields are coaxially arranged on the inner side of one of the slide wheels; thereby, one of the line liquids can be accumulated on a surface when the slide is slid, and the two shields can limit the liquid of the twist line Lateral spray. Document GB-A-2101181 (Smrt) discloses a mask disk (41, 42) having a generally cup-shaped inner surface to accommodate a draw line of liquid. Document GB-A-2111568 (Texalon) discloses a separate rigid flat shield disk (3). Document US-A-3,700,144 (Smrt) discloses a mask 80 having a central opening through which a spray from a can is passed, and the mask is made of a suitable absorbent material to Prevent dripping of liquid from the rifling that does not pass through the opening. Document EP-A-1,059,386 (Tricor) discloses a masked disc assembly, 7 200900557 〇), the grounding and abandonment and 28 will be modified to spray the coating onto one of the surfaces (25) The paint twister (1 applies together and includes a disk (24) having a front side (58) that contacts the paint sprayed from the twister toward the surface. An absorbent pad (62) is mounted to the plate The front side (58) absorbs the overspray in use to provide a clear coating line to the surface. This document also discloses a pair of surface rear wheels 64 that can be rotated and mounted by a rearwardly extending bracket 66. The frame 12 is spaced outwardly relative to the front wheel to avoid damaging the rigid line. Figure 13 of the document US-A-5,690,740 (Smith) discloses a spray gun with a directional air curtain from a pneumatic chisel 12 54 Inhibits spray reflection. Place shields 70 and 72 between spray cloud 50 and pneumatic chisel away from the surface being sprayed.

None of the prior art twisting devices described above utilize airflow to define the shape of the spray line liquid. Document US-A-5,690,740 (Smith) is used for a different skill/issue, i.e., to prevent spray reflection, and does not disclose a shape defining edge or airflow at the (shape-defining) edge. In one embodiment of this first aspect, the mask includes a conduit for transporting gas from a source to the shape defining edge. The conduit can include at least one aperture coupled to the contoured edge described above, and the airflow is substantially directed past the contoured edge. In a preferred embodiment of this first aspect, the gas source is a battery powered gas impeller. In another embodiment of this first aspect, the wheeled line apparatus includes at least a gas flow conduit and a battery powered pneumatic impeller disposed in the hub region of the opposing wheel. 9 200900557 In accordance with a second aspect of the present invention, a wheeled line device includes a ballast wheel coupled to the apparatus and movable relative to the apparatus between laterally extending and closing. In one embodiment of this second aspect, the apparatus is equipped with a rocker arm that terminates in a caster. According to a third aspect of the present invention, a spray operating device includes at least a spring device and a nozzle valve opening mechanism, the spring being mounted between a spray body and a holder, and the spray body Movably mounted in the holder, the spring means is tilted to cooperate with the action of the spray valve spring; the nozzle valve opening mechanism acts in conjunction with the mechanical advantage of the spring means relative to the spray body. The mechanical advantage can be provided by a bell crank that pivots to the gripper and has an arm that acts on the spray body and the distal trigger arm that is longer than the arm that acts on the spray body The machine is used to expand the force applied to the distal trigger arm to resist the inclination of the spring device. One embodiment of this third aspect includes an actuating structure that is removably secured to the k spray body and that can be acted upon by a spring device and/or a mouth valve opening device. In the preferred case, the actuation structure includes a clip for removably receiving the aerosol body therein, such as engaging the aerosol body at one end of the valve. The clip can also engage adjacent the valve spray body. According to a fourth aspect of the present invention, a twisting device can be moved adjacent to a surface to spray a line of liquid onto the surface, the device including at least a positional transfer nozzle of a mechanically sprayed spray with a package 10 200900557 Having a mask to define a boundary of a spray field as the apparatus moves along the surface; the shield can be adjustably mounted to the center by a threaded shaft, according to a fifth aspect of the present invention, A line drawing device is movable adjacent to a surface to spray a line of liquid onto the surface, the device to a mask having a fixed edge to define a spray as the device moves along the face a boundary of the region; the cover is removably mounted in the device with the handle, and the protrusion is slidably received in a synergistic manner. According to a sixth aspect of the present invention, a line drawing device has a surface movable to spray a line drawing liquid onto the surface, the device having a mask having a fixed edge for the device edge The surface is defined as a boundary of a spray area; the mask comprises at least one drop device extending beyond the spray area and receiving a liquid accumulated on the mask to form a drip, thereby depositing a spray in use In accordance with a seventh aspect, a drawter spray nozzle includes an actuating support (e.g., a support flange) having a width greater than the width of a conventional spray nozzle. The actuating support is received in a correspondingly enlarged set of sockets or apertures in a compatible line drawing device. As a result, conventional spray nozzles can be trapped in the enlarged seat or orifice and cannot be effectively utilized in such a line drawing device. The nozzle may also have a function, such as a diametrically opposed lug that forms an acute angle with one of the elongated outlets of the nozzle. The subsidiary item in the scope of the patent application defines that the various mist zone devices of the present invention have a near-small package. The table adjacent to the small bag moves to form a line 〇 at least one, and thus the directional aperture pattern 11 200900557 Various preferred features in the process. [Embodiment] As schematically illustrated in Fig. 1, a spray mask 10 can be used to define the shape of a liquid spray on a surface, which comprises at least a pair of plates 12, 14 mounted on a spray The nozzle 18 of the agent 20 sprays any lateral side of the spray of liquid 16; the pair of masks can define the width of the spray liquid. The lower edges 22, 24 of the mask are as close as possible to the surface of the line that is intended to be sprayed. However, a vertical gap A must be left to leave enough space for surface irregularities. It is known that a gap between 2.5 and metric is sufficient in most cases. In known devices, this spacing results in some degree of overspray that exceeds the lateral spacing of the plates. Similarly, the spray line liquid will accumulate on the inner surface and will collect some drops along the lower edge in the form of drops or droplets. Generally, it will drip onto the spray surface, mainly in the spray line. outer. Both of these effects, overspraying and drawing liquid drops, may be known as the edge of the line of the spray equipment of the twisting device, and the line sharpness is damaged. According to one embodiment of the first aspect of the present invention, a specific embodiment The air is located at the conduits 28, 30 outside the masking plates 12, 14 and reaches the apertures 3 2, 3 4 adjacent to the edge 2 2, 2 4 of the mask. The aperture extends along the length of the lower edge 24 of the mask and just outside of it and forms an angle to direct an airflow 36 inwardly through the lower edges 22, 24 of the mask. The flow can direct the over-sprayed liquid and liquid droplets back onto the fog line, resulting in significantly clearer line definition. When the mask is drawn on the line, set the mask cover to the 5.0 line. This edge blur 〇 passes through the lower edge 22, and the gas can be sprayed to the spray 12 200900557. The second to the first embodiment illustrate a wheel-drawn line device of the first embodiment of the present invention according to various aspects of the present invention. The equipment is mainly made up of plastic implants and one of the components. The apparatus generally includes at least one body 4 (Fig. 6 to 1) that slidably engages one of the holders 41 of the spray can. Alternative bare arm 42

Each of the conduits 78 terminates in abutment with a lower edge of the cover plate 2, 2 4 adjacent to one of the elongated apertures 3 2, 3 4 . The aperture extends along the length of the lower edge of the side mask 2 2, 2 4 and is located just outside thereof and forms an angle of about 45 degrees to direct a flow of air substantially downwardly and inwardly across the cover. The lower edges 22, 24 of the hood. In use, switch 80 is operated to open blade 74, pull trigger 46^ to open the spray, and to spray a line as the device is slid forward. The airflow from the conduit apertures 3 2, 3 4, and longitudinally along the edge of the mask and down the location, laterally containing the overspray draw liquid and plotting along the lower edge of the mask The liquid droplets are blown back onto the spray line to create a sharply painted spray line. In a specific embodiment of the second aspect of the present invention, one pair of rocker arms 102, 104, respectively, which are respectively connected to one of the casters 106, are pivotally connected to one of the side members 62, respectively. Rear corners and laterally retracted or closed along a vertical axis, extending 45° laterally in one of Figures 2 and 4 and 3 and 5 (left arming (J arm 102)) Swing between the side members/rocker pivots (not shown here) to suspend from each extended and retracted position and optionally from one or more intermediate positions Open rocker arm. Obviously, the most stable position is when the arms are extended laterally, but when one or the other arm is closed, a line can be sprayed close to a wall or a similar one while maintaining a certain degree of laterality. Stability: The rocker arm 102, 104 in its closed position still leaves the caster outside the spray line. Closing the arms reduces the overall size of the device; facilitates transport packaging and storage. 14 Ο 200900557 The spray line is provided with a nozzle 1〇6 relative to the design of the holder, and the spray is moved during use. By the nozzle, the turtle is solidified and the spray canister 108 valve. As shown in Figures 6 to 8, to counteract the load of the meal and then open - in the holder 41 - with two: Ming 'spray nozzle 106 is located in a specific embodiment, the frame 1 1 〇. The third structure of the present invention can cope with the clip U2 in the missing device 41, and the frame side 2 of the outlet end of the aerosol can is located at the lower end 57 At the bottom, the longer arm 2 is at the end % buckled into the recess; 5 s ^ extends to the cymbal shaft for the operating arm 42 and the other shorter arm 12 is pivotally coupled to the clip 112 The bell-shaped crank is tilted upwards. The pull-up belt 124: J (made of the appropriate material, connected to the crank at the operating arm 4 or end) f 116, extending at ' and the upper portion of the strap 4 engages the trigger 46. Pulling the crank 114 and applying force to the actuating clip ι 2, and thus spraying downwardly against the nozzle holder to open the connection to the spray The outlet of the spray 1 is wide. Since the spray can 108 has been locked to the actuating strip " 2 (i.e., 'resisting the nozzle opening (4)) by using the 123 or the like of the bullet, the outlet valve can be lowered. Accidental opening. Known line drawing devices rely on nozzle valve springs to resist accidental opening, however, in the present invention, the bell crank 1 14 mechanical expander 'which is capable of providing a relatively large trigger action remains relatively large' The mechanical advantage 'to tilt the spring 123. The greater the inclination of the spring, the more resistant to accidental discharge of the spray. The lower limit of the aerosol to the outlet is the over-discharged can [18, one hub; ; The other lower machine aerosol agent 106 is enough to reduce the spring as a situation.

One of the protrusions may be knurled via the body 40 to rotate the thumb wheel and centrally position the shaft. The distal ends of the shafts can each mate with an internally threaded sleeve or in-line (not shown) of one of the side members 62. The thumb wheel 6 6 can be rotated to vary the mask spacing and thus the width of the spray line can be varied between 50 and 100 mm. Figure 2 illustrates the side member 62 and the mask in its closest (50 mm) setting, and Figure 3 illustrates it in the widest (100 mm) setting. The threaded shaft can easily and accurately set the line width to any desired value within this range. The side members 62 can also be locked to the selected spacing. Other embodiments may be readily modified to produce lines that are wider or narrower than those described in the specific embodiments. The holder 41 can be vertically moved relative to the body 40 at three heights. The height can be set by a spring load button 52 located on either side of the body 40, and the button can cooperate with a series of verticals in the holder 41. Height fixed hole 5 4 application. Figure 2 illustrates the spray at its lowest position and the figure at its highest position. The button position allows the gripper-arm assembly to be easily removed from the body, such as when packaged in a storage case.

The front edge of each of the mask panels 12, 14 has an arched shape toward the inner flange 90 and a rearwardly projecting tab 92. The depth of the flange 90 (i.e., the convex dimension of the line drawing device in the width direction of the masking device) can conform to the width of the side member 62 and the mask plates 12, 14 when they are close to the setting. The flange 90 is bent downward and rearward and can be shielded from the spray area. The tabs 92 assist in the insertion and removal of the mask panel 12, and the lower edges 22, 24 of each mask panel are chamfered at 94, 96 positions. Inevitably, some spray lines are drawn. The liquid will deposit on the mask in areas where it cannot be effectively controlled. Although this deposition does not directly spray the line clarity, when the line has been sprayed and the device is self-starting, it will cause some liquid drops after use. The board can be easily removed for cleaning or replacement. Figures 11 through 16 illustrate an additional line drawing device that is similar to that described above with reference to Figure 10, and which similarly embodies the aspects of the present invention. The difference between such further equipment and the aforementioned equipment is only in the main form. The operating arm is best shown in Fig. 14. The operating arm 42 includes at least one upper mask inner wall covering until the front of the lens is moved to the front surface. 200900557 It can be telescopically moved within a lower section 42b. It is thus possible to reduce the length of the arm 42 during packaging, transportation and storage, such as in a shipping box (not shown here). As shown in Fig. 14a, the drawstring connecting the bell crank distal trigger arm 116 to the trigger 46 is comprised of two separate sections 124&, 12 servants. The portion 1 24a has an eyelet 丨 23 at one end through which the knife 124b can be slidably received. The portion 124b has a hooked end portion 125 that engages the eyelet 123 when the operating arm 42 is fully extended to allow the drawstring to be pulled and to move the trigger 46 to the bell crank arm 116. Portions 124a, 124b may be made of plastic, but in the preferred case are made of a resilient metal to provide additional toughness and resistance to stretch. Nozzle Nozzle 106 is similar to that described above, but is more clearly illustrated in Figures 15-17. As best illustrated in Figure 15, the nozzle has a discharge joint 150 having a generally rectangular outlet orifice I52. The long axis of this orifice must be oriented so that it traverses the equipment in use to provide a generally fan-shaped, laterally extending spray pattern. For the purpose of the actuator/valve, the nozzle is provided with an intermeshing support that includes at least one generally circular flange 154 having a pair of diametrically opposed directional lugs at the holder bracket n〇 A nozzle change housing 170 is provided. In the inner side wall of one of the sleeves 170, the corresponding diametrically opposed recesses 258 are formed to receive the directional lug 1 56 to enable the laterally arranging the outlet apertures 152. The nozzle can be mounted in the spray valve discharge tube' and can be lowered from above into the housing 17〇. To assist in properly mounting the directional lug' recess 258 has a peripherally extending ramp 260 that extends from the extension of 200900557. At the upper end of the joint 150 (Fig. 16), a seat 1 62 can be used to receive the spray discharge tube. Corresponding to the recess in the holder bracket 110, the lugs are placed diagonally (an acute angle to the long axis of the outlet) to ensure the alignment of the nozzle outlet apertures 152. The diameter of the nozzle flange and the receiving sleeve may be larger than the nozzle (valve actuator) used in conventional rifling. Thus, the twisting device can be compatible with a spray canister equipped with a nozzle having a large flange and/or a diagonally oriented lug and a canister having a standard nozzle/valve actuator. These will fall out of the pedestal 170 and/or will not be oriented correctly or for long periods of time. The pneumatic inlet port is utilized in the wheel blanking plate 68 to form a pneumatic inlet port opening 173 adjacent the central portion of the impeller, instead of being placed toward the impeller casing 72 and facing inwardly toward the orifice 73 of the apparatus. The impellers are not shown in Figures 11 through 18, but are arranged oppositely on the motor shaft as compared to Figure 7. Thus, in the apparatus of Figures 11 to 18, the impeller rotor plate 75 7 is placed inwardly toward the motor, and the impeller blades 77 are outwardly directed toward the wheel plate 8 and around the inlet opening 173. In order to allow air to be introduced downwardly into the opening 1 7 3 via the wheel 158, the wheel has spokes 159. When the wheel introduces air from the outside of the device, there is still a slight risk of drawing the spray liquid into the impeller and the associated conduit. Masking panels These masking panels have been modified to have an inwardly curled rear surface with a dispensing aperture, but the center of the circle of the sleeve is shown in the direction (the first obscuration. 160 via the rifling contour 19 200900557 292, The masks modified by the expansion of the spray crepe coating behind the applicator are mirror images of each other, so only one 214 is described below. The mask 214 is crimped inwardly and rearwardly to form a curl 292 ° in the present invention. In a specific embodiment of the sixth aspect, the inboard portion 214 is provided with an inwardly projecting beveled region 134 which, before reaching the chamfered lower edge 296, provides a mist line. The foot or ridge, the edge 296 extends downwardly and inwardly. The spray body of the region 215 is touched, and the liquid is recorded along the surface of the mask plate 2 14 downward and toward the chamfered edge. 9 6 and the foot is pointed toward the drip, and/or is blown there by the airflow discharged from the conduit orifice. 延伸 extends above the liquid line 298 of the rifling. The tip is discharged from the liquid line of the rifling 298. The tip is molded Exhaust before it becomes too large. Over-drip may form a "sludge" on the mark. A simple type of liquid spray equipment in the sputum line may not require a gas flow conduit and a connected gas source, so the reference may be omitted. Rim line device description of the present invention, the present invention is used to spray any shape, such as a closed edge profile, a mask having a perforated shape, and a gas conduit located around the orifice can be readily applied to a hand held spray. BRIEF DESCRIPTION OF THE DRAWINGS [Embodiment of the drawings] A specific embodiment of the invention is described with reference to the drawings, in which: the two types of masks are arranged after the profile* in the mask so as to be coated with a lower smog line Liquid .296 ° Draw end 2 94 stream i tip 294 drops, because it can make the drop surface i in the form, it can be easily required.
