- the present invention relates to a garden nozzle with a pattern switching button on the handle so as to change patterns of watering by one hand only.
- a conventional garden nozzle is disclosed in Fig. 1 and generally includes a barrel 10 with a handle 11 through which a path 111 is defined so as to be connected with a hose which is not shown.
- a rod 12 is movably extended into the barrel 10 from a rear end of the barrel 10 and a lever 15 is connected to the rod so as to pull the rod 12 backward.
- a collar 13 is engaged with an opening of the main path 112 in the barrel 10 and a pattern member 14 is rotatably mounted to a front end of the barrel 10.
- a positioning device 16 including a bead and a spring is used to index the position of the pattern member 14 which further includes an outlet 141 which is in communication with one of the pattern holes in the pattern member 14 and the main path 112.
- the present invention intends to provide a pattern switching button for rotate the pattern member and the button is located on the handle of the nozzle so that the user can operate the button by the hand holding the handle.
- the present invention relates to garden nozzle which comprises a barrel and a handle is connected to the barrel.
- the handle includes a path which communicates with a pipe in the barrel.
- a trigger is pivotably connected to the handle and has a valve engaged with the path.
- a pattern switching button is movably connected to the handle.
- a pattern member is rotatably mounted to a front end of the barrel and a shaft has a first end fixed to the pattern member and a spiral groove is defined in an outer periphery of a shank of the shaft.
- a tube is movably mounted to the shank and a spring is biased between one end of the tube and an inside of the barrel. Two holes are defined through a wall of the tube and a first pawl and a second pawl are respectively and pivotably engaged with the two holes.
- the pattern switching button is connected to and moved with the tube.
- a sleeve is mounted to the shank and received in the tube.
- a ridge extends from an inner periphery of the sleeve and is movably engaged with the groove in the shank.
- Two recesses are defined in an outer periphery of the sleeve and the first and second pawls are engaged with the recesses respectively.
- the second pawl has a side wing extending outward therefrom which is pushed by a protrusion in the barrel to pivot the second pawl away from the recess when the tube is moved by pulling the pattern switching button.
- the garden nozzle 20 of the present invention comprises a barrel 22 with a pipe 221 located therein and a handle 21 is connected to the barrel 22.
- a path 212 is defined through the handle 21 and the pipe 221 is in communication with the path 212 which is to be connected with a hose which is not shown.
- a trigger 211 is pivotably connected to the handle 21 and has a valve engaged with the path 212 so as to control the path 212 to allow water entering the path 212.
- a pattern switching button 40 is movably connected to the handle 21 and located above the trigger 211.
- a pattern member 23 is rotatably mounted to a front end of the barrel 22 and includes six pattern outlets 231 defined therethrough.
- a shaft 80 has a first end 83 fixed to the pattern member 23 by a screw 232 and a spiral groove 811 is defined in an outer periphery of a shank 81 of the shaft 80.
- the shank 81 located in the barrel 22 and a gear 82 comprising six teeth as shown in Fig. 6 is co-axially secured to the shank 81.
- the shank 81 extends through a disk 90, a central hole 71 in a frame 70, a passage 53 in a sleeve 50 which is received in a tube 30, and is rotatably received in a receiving portion 220 in the barrel 22.
- the disk 90 is located beside the pattern member 23 and fixed to the barrel 22 by extending several screws through holes in the disk 90 and fixed to connection tubes in the barrel 22.
- the shaft 80 extends through a central hole 92 in the disk 90.
- the disk 90 has a tubular portion 93 in which the pipe 221 in the barrel 22 is received and sealed by a seal ring 24.
- An annular recess 91 is defined the one side thereof so as that the gear 82 is rotatably received in the annular recess 91.
- a stop member 94 together with a torsion spring 95 are connected to the disk 90 and the stop member 94 is engaged with one of the teeth of the gear 82.
- the stop member 94 and the teeth of the gear 82 are shaped to have an inclined surface such that the gear 82 together with the shank 81 are allowed to be rotated in one direction.
- the tube 30 is movably mounted to the shank 81 and a spring 32 is mounted to the shank 81 and the receiving portion 220, and biased between one end of the tube 30 and an inside of the barrel 22.
- Two holes 34 are defined through a wall of the tube 30 and a first pawl 60 and a second pawl 600 are respectively and pivotably engaged with the two holes 34 at two respective pivots 61 of the two pawls 60 and 600.
- the tube 30 includes a longitudinal extension 31 and the barrel 22 includes a guiding portion 222 therein, the longitudinal extension 31 movably inserted in the guiding portion 222.
- the pattern switching button 40 includes two lugs 41 which are connected to the tube 30 and a screw 42 extends through the pattern switching button 40 and fixed to the tube 30, such that when pulling the pattern switching button 40, the tube 30 moves backward therewith.
- the sleeve 50 is mounted to the shank 81 and located in the tube 30.
- a ridge 54 extends from an inner periphery of the sleeve 50 and is movably engaged with the groove 811 in the shank 81.
- Two recesses 51, 52 are defined in an outer periphery of the sleeve 50 and the first and second pawls 60, 600 each have a projection 62 which is engaged with the recess 51/52 corresponding thereto.
- the second pawl 600 has a side wing 64 extending outward therefrom which may be pushed by a protrusion 223 in the barrel 22 to pivot the second pawl 600 away from the recess 52 when the tube 30 is moved backward as shown in Fig. 7B.
- the tube 30 further includes three insertions 35 extending from the other end thereof and the frame 70 includes two engaging notches 73 with which the three insertions 35 are engaged.
- a first positioning spring 63 is biased between the first pawl 60 and a side extension plate of the frame 70
- a second positioning spring 630 is biased between the side wing 64 of the second pawl 600 and the rear surface 72 of the frame 70.
- the tube 30 and the sleeve 50 which are secured by the two pawls 60, 600 are moved backward.
- the movement of the sleeve 50 rotates the shank 81 which drives the pattern member 23 to rotate 60 degrees which is the angle between two adjacent teeth of the gear 82.
- the user can operate the pattern switching button 40 by the hand holding the handle 21.
- the spring 32 pushes the tube 30 together with the sleeve 50 forward and because the shaft 80 cannot rotate in opposite direction, the sleeve 50 and the tube 30 are rotated along the shaft 80 and back to their original position.
