Detailed description of the present invention

The toy water gun of the present invention has been developed to provide safe water shots and of great power, at the same time that it is totally autonomous, that is, without the need for batteries or pressurized gas cartridges or media external pressurization, such as tap water or garden hose. Also, the toy water gun of the present invention provides relatively constant pressure for the entire duration of the shot. It is based on manual pumping for fill a chamber with water that will store the water under pressure created by the expansion of the elastic chamber for a shot later. In some preferred embodiments, provides a considerably large nozzle opening for achieve the shotgun effect mentioned above. Bliss nozzle can have a very large diameter compared to known previous water guns, the diameter of which is, approximately 1 cm (three eighths of an inch) or greater.

Next, referring to Figure 1, the operation of the form of embodiment of the present invention. Figure 1 is a view side of the water gun toy 1 shape embodiment of the present invention with a main housing 3, a handle 5 and a barrel 9 with nozzle 11.

The chamber 13 is located inside the box 15. The chamber 13 has a front end 17 and a rear end 19 and It is cylindrical, but could have another shape without departing from Scope of the present invention. In this embodiment, the front end 17 serves as both an entry and a an outlet, but the water gun could be set to so that the back end did the times of exit or vice versa. The rear end 19 includes a clamp 22 as well as a camera holder 20 surrounding the clamp 22. The clamp 22 holds the cap 24 to the rear end 19 of the chamber 13 and connect the rear end 19 of the chamber 13 to the support chamber 20. The camera holder 20 moves towards the part rear of the gun when chamber 13 is dilated (full) and moves back to its resting position (shown in the Figure 1) during camera release. Front end 17 has a tube 21 connected to it by means of the clamp 23. The tube 21 is connected to a connection in "and" 25 which is  connected to tube 27, which is connected to a pump that described below. Also, connection 25 is connected to the tube 29 that is connected to a chamber discharge valve 31 which is analyzed below.

The operation of the water gun Toy 1 of the present invention is illustrated by reference, to at the same time, both Figure 1 and Figure 2, the parts being identical, corresponding to both figures, numbered so identical Figure 2 shows a partial view in section, with the chamber 13 and related housing removed to show the pump 45 and its operation. Toy water gun 1 is operated filling or partially filling the water tank 33 through a filling hole 35 after removing the cover 37. As shown, reservoir 33, is connected to the main gun housing of water 3, as shown. "Connected" means physical or fluidly connected to the gun directly or indirectly or contained internally within it or forming a single piece with the same. The lid 37 has a small ventilation hole (no sample) to allow air to enter, but to prevent leaks of water and prevent the formation of a vacuum in the tank 33. The tube that goes from the pump to the tank 39 is connected to the pump 45 e includes a unidirectional valve 41 that allows water to enter in the pumping cylinder 47, but do not re-enter the reservoir 33. The displacement of the piston 57 inside the cylinder of pumping 47 causes the displacement of water from the tank 33 up to chamber 13. Pump rod 59, which connects the piston 57 to the sliding handle 55, actuates the piston 57. The rod pumping 59 is anchored to slide handle 55 and is holds, slidably, in place by means of the block 61.

The user manually activates the handle of sliding 55. The user holds the sliding handle 55 with one hand and the handle of the gun 5 with the other. The handle of slip 55 moves back and forth to everything along the length of its trajectory, making block 61 the butt times In the escape race, the back movement ahead it is transferred from piston 57, which draws water from reservoir 33 through tube 39 and through a flow valve unidirectional 41, to cylinder 47. In the intake stroke, the cylinder water 47 is pressed (or pumped), through the tube 27 and through the connection in "y" 25, in tube 21 and in chamber 13 for dilation and filling thereof. The water is pumps the chamber 13 by means of the pump 45 until the chamber 13 is full. Water will also enter tube 29, but it will not will eject through the outlet tube 65 or the nozzle 11, given that the discharge valve 31 will be closed until it is tightened trigger 7. Once dilated, valve 31 prevents water from chamber 13 flows freely through outlet tube 65.

Next, referring to Figure 3, considered in relation to Figures 1 and 2 being the pieces Identically numbered identically, parts of the discharge valve 31 in a sectional side view. The elevator of articulated trigger 71 is connected to trigger 7 by means of a joint 72 (Figures 1 and 2) and is coupled so sliding to the drag rod 73. Spring 75 and stop 77 they act together with trigger lift 71. Stop 77 is fixedly coupled to the drag rod 73. The rod drag 73 has, at its opposite end, a universal connector spherical flexible connection 83. It can rotate slightly inside valve plug 84. When trigger 71 is pressed, the joint 72 causes the trigger lift 71 to compress the spring 75 to the left and press on stop 77 to move the drag rod 73 and the valve plug 84 with the valve shutter 85 to the left. However, the pier 79 and the water pressure inside the chamber 86 apply forces that tend to hold the valve plug 84 and the valve plug 85 in the closed and sealed position. When enough is applied compression pressure to the trigger, spring 75 pushes the stop 77 to the left, therefore, the valve plug 84 and the valve shutter 85 are placed to the left for a rapid release and expulsion of water caused by the forces of compression of the chamber full of water 13. This creates the effect of desired burst and increases the rate and distance of the water expelled

Figures 4 to 6 show side views, simplified, partially in section of a chamber 13 of a toy water gun of the present invention in various dilatation states In this embodiment arrangement preferably, camera 13 has a predetermined inflation size and box 15 has a size smaller than the total size of default dilation

In Figure 4, camera 13 is shown in its resting position (empty, without dilating), the pieces being identical numbered identically, but showing more pieces of camera 13. Camera 13 includes a "bubble" part preformed 91, which is weaker than the rest of the chamber 13 and, for Therefore, it improves dilation in that position. Preferably, the chamber 13 includes a wall 93 that is narrowed in the state without expand, the wall having a smaller diameter towards the end rear 19 and a larger diameter towards bubble 91 and towards the front end 17. The smaller diameter section needs more pressure to expand than the larger diameter section. For the therefore, the dilation begins in bubble 91 and moves towards the rear end 19. Chamber 13, first, expands radially and, subsequently, it expands longitudinally to provide flow more constant when released.

Box 15 serves as a camera guide and limits the expansion of chamber 13 to prevent it from exploding and to support the weight of water. Box 15 can be described. regarding the pressurization of the chamber air. For example in the preferred embodiment, the diameter of the chamber 13, without inflate, may be approximately 1.9 cm (three quarters of inch) and fully inflated with 25 psig, can have a diameter approximately 10.1 cm (four inches). The size or Total camera capacity depends on the length of the camera. The box 15 can have a diameter of, for example, approximately, 8.9 cm (three and a half inches). This box limits the expansion and Helps make dilation and release occur so constant. Therefore, in Figure 4, camera 13 is in repose. In Figure 5, water pressure is applied to cause a initial dilation This is created with the force of the pump 45 introducing water into the chamber 13. First, the bubble 91 it is dilated like bubble 91 ', shown in Figure 5, and dilation occurs first at the outlet end 17 and what does radially. Then, when more water is added, the chamber 13 will expand laterally downward from box 15, to fixed pressure and rhythm, as shown as dilated part 91 '' in Figure 6. Also, the contraction of the chamber 13 will cause the water release and at a relatively constant pressure it You will get a steady rate of expulsion.

Fig. 7 is a side view of another form of realization of a toy water gun 101 according to the present invention. The toy water gun 101 is similar to the first embodiment and includes a main housing 103, a handle 105, a trigger 107 and a barrel 109 with nozzle 111. In this embodiment, the nozzle 111 is circular and has a opening with a diameter of approximately 1.1 cm (seven sixths inch)

The chamber 113 is located inside the box 115. The camera 113 has a front end 117 and a rear end 119 and is usually cylindrical, but it could have another shape without departing from the scope of the present invention. In this way of embodiment, the front end 117 serves as much of an entrance as of an exit, but the water gun could be configured so that the rear end 119 did the times Exit or vice versa. The rear end 119 includes a clamp 122 that holds the plug 124 at the rear end 119 of the camera 113 and also includes a camera holder 120 which surrounds clamp 122 and which is connected to it. The support of chamber 120 moves toward the rear of the gun when chamber 113 is dilated (full) and moves back to its resting position (shown in Figure 7) during release of the camera. The front end 117 has a tube 121 connected to it by means of the clamp 123. The tube 121 is connected to chamber 125 that is connected to tube 127, which is connected to a pump, which is described below. Also the camera 125 is connected to a chamber discharge valve 131 and It contains the same, which is discussed below.

The operation of the water gun Toy 101 of the present invention is illustrated by reference, at the same time, both Figure 7 and Figure 8, the identical pieces, corresponding to both figures, numbered of identical way. Figure 8 shows a partial view, from below, in section, with camera 113 and related housing removed for show a bomb, which is not in Figure 7 or 8, and a valve arrangement. The toy water gun 101 is it acts by filling or partially filling the water tank 133, to through a filling hole 135 after removing the cover 137. The Cap 137 has a small vent hole (not shown) to allow air to enter, but to prevent water leaks and prevent a vacuum from forming in the tank 133. The tube that goes from the pump to tank 139 is connected to pump 145 and includes a unidirectional valve 141 that allows water to enter the pumping cylinder 147, but do not re-enter the reservoir 133. The displacement of piston 158 inside the cylinder pumping 147 allows the displacement of water from the tank 133 to chamber 113. Pump rod 159, which connects the piston 158 to slide handle 155, actuates piston 158. The user manually drives the slide handle 155. The user holds the sliding handle 155 with one hand and the pistol handle 105 or upper handle 167 with the other. He sliding handle 155 moves back and forth throughout the length of its trajectory. In the race of escape, the backward movement is transferred from the piston 158, which draws water from reservoir 133 through tube 139 and passing by a unidirectional flow valve 141, to cylinder 47. In the intake stroke, the water in cylinder 147 is under pressure, through unidirectional valve 144 and chamber 125, in the tube 121 and chamber 113 for dilation and filling of the same. Water will not be expelled through nozzle 111 since the discharge valve 131 will be closed until the trigger 107. Water is pumped to chamber 113 by means of the pump  145 until chamber 113 is full.

Pressure relief valve 146 prevents a excessive pumping to chamber 113 opening and allowing water pass from pump 145 back to tube 139 and reservoir 133 a Once a predetermined pressure is achieved. Once dilated, valve 131 prevents water from chamber 113 from flowing freely through outlet tube 165 to nozzle 111.

Following with reference to Figure 9, considered in relation to Figures 7 and 8, the pieces being Identically numbered identically, parts of the chamber 125, which has the discharge valve 131, in one view lateral cut. The articulated trigger lift 171 is connected to trigger 107 by means of a joint 172 (Figure 7) and is slidably coupled to the drag rod 173. Spring 175 and stop 177 act in conjunction with the elevator trigger 171. Stop 177 is permanently coupled to the rod of drag 173. The drag rod 173 has, at its end opposite, a flexible spherical universal connector 183. The it can turn slightly inside the valve plug 184. When trigger 107 is pulled, trigger lift 171 compress spring 175 to the left and push stop 177 to move the drag rod 173 and the valve plug 184 with valve plug 185 to the right. When applied enough compression pressure to the trigger, spring 175 pushes the stop 177 to the left, therefore, the valve plug 184 and valve plug 185 are placed to the left for a rapid release and expulsion of water caused by compression forces of the chamber filled with water 113. This creates the desired burst effect and improves water rhythm and distance expelled In some embodiments, springs 175 and 179 are balanced so that once the shutter of valve 185 opens, does not close until the internal pressure is almost zero This keeps a burst of shots unique and fast.

It should be admitted that the water guns of toy of preferred embodiments of the present invention, which have the box around the camera, will allow repeated shots with the same explosion of water and, consequently, constant shots until the camera is substantially fully deflated.

Figure 10A shows another embodiment of a chamber 401 according to the present invention, which is an element hollow tubular 403. It has a first end 411 and a second end 405. Located in the area of the first end 411 there are a weakened section 413. In this case, weakened section 413 it has the normal shape of a bubble, but it could have any another form without departing from the scope of the invention, for example, an enlarged ovoid or elongated shape. This is the point of initial dilation described in relation to Figure 4 previous. Also, the tubular element 403 has a unique shape. developed to stimulate dilation, first, radially in weakened section 413 and subsequently longitudinally of right to left (from first end 411 to second end 405). In this embodiment, the camera 401 has a thicker wall 409 at the second end 405 and a thinner wall 407 at the first end 411. Also, the first end 411 has a dilatation neck, as shown, to fit over a inlet / outlet tube and, when coupled in that way, it is not Subject in the previous.

Figure 10B shows another alternative camera 501, with a weakened section 503, a first end 507 and a second end 505. In this case, the tubular element 509 has a wedge diameter (variable) with a larger diameter 511 in the first end 507 and a smaller diameter 513 at the second end 505. It they can alternatively use combinations of thicknesses wall variables, shown in Figure 10A, and of the variable diameters, which are shown in Figure 10B.

Figure 11 shows a side view in section partial of the water gun 1 without showing the aspects Main water gun, except a cannon and a nozzle. While the barrel and nozzle are preferably used with the water gun 1 described above, manufacturers specialized will recognize, thanks to this description, that the barrel and nozzle can be used with any water gun standard. They would include pumping water guns, such as described in the information description statement previous, water guns with camera, shooting water guns rear, and any other water guns that are available or available.

Also, Figure 11 shows the tube exit 65, which can be located inside the barrel of a gun of water toy, or you can understand the barrel of any toy water gun, as indicated above, with a large diameter nozzle 11 contained in the cover of the nozzle 209. The outlet tube 65 or barrel has a section front 211 that is specifically designed to receive a turbulence control element 213. The control element of turbulence 213 is shown in its side view in section and has a tube bundle, such as the 215, 217 and 219 pipes that pass parallel to the elongated length of the outlet tube 65 and make the times of linear current guide walls. This improves the expulsion of laminar flow of water through the nozzle 11. It get an additional improvement with the optional use of filters, such as filter 221, placed against the rear end of the element of turbulence control 213, filter 223, placed against the front end of the turbulence control element 213, and the filter 225 separated from filter 223 in front of the control element of turbulence 213 and against the nozzle cover 209, as sample.

Figure 12 shows a front view of the nozzle shown in Figure 11. The nozzle 11 contained in the nozzle cap 209 is exposed behind its filter 225, as shown.

Next, referring to Figure 13, an enlarged cross-sectional view of the element is shown of turbulence control 213 shown in Figure 11. By therefore, the turbulence control element 213 has a tube outer hole 214 and contains a plurality of parallel tubes elongated and hollow, such as tubes 215, 217 and 219.

Next, referring to Figure 14, another embodiment of a control element is shown of turbulence 251. It is formed in a single structure and includes a front section with flange 253 that can include a nozzle hole or can be placed inside a barrel structured in a manner similar to that described in relation to the first embodiment of the nozzle with a cover of nozzle located in front of it. Additionally, they can be include optional filters in front of the control element of turbulence 251 or behind it or both in front of and behind the same. An elongated portion 255 has been formed with a plurality of linear current guide walls, such as walls 257, 259 and 261, along with others, as shown. These guide walls linear current radially enter a central axis imaginary and pass parallel to it for maximum control of turbulence

While the linear current guide walls shown in Figure 14 are linear and move towards a central axis and linear current guide walls of Figure 13 comprise tubes, any reasonable geometry will help control turbulence whenever the guide walls of linear current, generally, pass substantially parallel to the central axis of the barrel to establish the flow of liquid to substantially reduce turbulence. This allows you to exit the nozzle a more laminar projection of water, which at the same time Keeps the water together for longer shooting distance. For the therefore, the specific geometry selected will depend on the decision manufacturer.

For example, Figure 15 illustrates a view front of a turbulence control element 271 with a plurality of tabs that serve as guide walls of linear current It includes an elongated outer tube 273 and parallel tabs represented by tabs 275 and 277 and tabs arranged at right angles to them, which they are shown as tabs 279 and 281. All these tabs they pass parallel to the elongated outer tube 273.

Also, Figure 16 shows an element of turbulence control 291 that can be formed in a single structure and that has a central core 293 with radial tabs extending outward, such as tongues 295 and 297, as shown.

The figure is exaggerated with respect to the thickness of the central core 293 and the turbulence control element 291 can ideally be formed in a single structure and can optionally use with one or more filters and be introduced into a water gun cannon near the nozzle.

Obviously, in view of the previous teachings numerous modifications and variations of this are possible invention. Therefore, it is understood that, within the scope of attached claims, the invention can be practiced in a different way than specifically described in the Present descriptive report.
