DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(29) FIG. 1 shows a prior art fluid valve assembly 10 connected in series within a portion of a fluid pipe 12 that extends along a longitudinal direction 26. The fluid valve assembly 10 includes a valve portion 14 connected to a valve handle 16. In many cases the valve portion 14 is of a ball valve, but could be any valve design or type known to those skilled in the art that control the flow of a fluid within. A fluid can include any liquid, gas or combination thereof. The valve handle 16 may include an extension 18 that is configured to contact a stop 20. In this way the rotation of the valve handle 16 is prevented from over-rotating in one direction. The valve handle 16 is generally described as being cantilevered from the valve axis of rotation 24. The valve handle 16 usually includes a couple bends 22 such that the cantilevered portion of the valve handle 16 is raised a distance above the valve portion 14 such that a user's hand can easily grasp and rotate the valve handle 16 about the axis of rotation 24. It is typical that 90 degrees of rotation ( turn) of the valve handle 16 can either stop the fluid flow through the fluid pipe 12 or allow fluid to flow through the fluid pipe 12.

(30) FIGS. 2 and 3 show a retrofit motorized actuator assembly 30 which comprises a plurality of separate components attachable to the portion of a fluid pipe 12 extending along the longitudinal direction 26. FIG. 3A is an exploded view similar to FIG. 3 to help show the various components of the retrofit motorized actuator assembly 30. As shown and described in FIG. 1, the manually actuated valve 14 is connected in series along the portion of the fluid pipe 12. The valve 14 includes a cantilevered valve handle 16 manually rotatable about the valve axis 24 that is perpendicular to the longitudinal direction 26 for opening and closing the valve 14.

(31) The retrofit motorized actuator assembly 30 includes a first pipe clamp 32a and second pipe clamp 32b each configured to fixedly attach to the portion of the fluid pipe 12 on either side of the valve 14. The clamps 32 are designed and configured to grasp the tubular shape of the fluid pipe 12. It will be understood by those skilled in the art that many types and designs of clamps 32 could be utilized to fixedly attach to the fluid pipe 12. As shown herein, the clamps 32 are of a two part design where a multitude of fasteners 34 and nuts 36 exert a force on the clamp to fixedly attach it to the fluid pipe 12. It is also understood that the nut 36 could be removed and the fastener thread directly into the opposite side of the clamp 32 to create a preload, which is applicable to all the fasteners or fastening methods described later herein. The clamps 32 also include a riser portion 38 with a plurality of apertures 40 at varying heights which is best seen in FIG. 3A.

(32) Attachable to the pipe clamps 32a and 32b respectively are a first adjustable bracket 42a and a second adjustable bracket 42b. Again, fasteners 34 may be used to fixedly attach the pipe clamps 32 to the adjustable brackets 42. The adjustable brackets 42 can be fixedly attached to the clamps 32 at varying heights due to the plurality of apertures 40. It is understood by those skilled in the art that there are a large variety of designs and configurations that would allow one to fixedly adjust the height between the clamps 32 and adjustable brackets 42 as this application is not limited to the specific embodiment shown and taught herein. In general, the first and second adjustable brackets 42 are configured to fixedly attach to their respective first and second pipe clamps 32, where each adjustable bracket 42 is translatably adjustable in relation to the pipe clamp 32 in a direction perpendicular to the longitudinal direction 26.

(33) The adjustable brackets 42 are then attached to a mounting plate 44. The mounting plate is best seen in FIG. 6 in a top view. The mounting plate 44 includes a set of bracket mounting apertures 46 disposed at both ends of the mounting plate that are configured to attach to the adjustable brackets. In this particular embodiment the bracket mounting apertures 46a are through holes whereas the bracket mounting apertures 46b are slotted. The slots 46b allow for tolerance when attaching the mounting plate 44 to the adjustable brackets 42. The slots 46b could have also been through holes similar to 46a. In summary, the set of bracket mounting apertures 46 are configured to attach to their respective adjustable brackets 42 with fasteners 34 or the like.

(34) A motorized actuator 48 is configured to attach to the mounting plate 44. Therefore, the mounting plate also includes a set of actuator mounting apertures 50 disposed between the bracket mounting apertures 46. The mounting plate 44 also includes a drive slot 52 which accommodates a drive shaft extension of the motorized actuator to penetrate there through. The set of actuator mounting apertures 50 and drive slot 52 allow the motorized actuator to be placed at a variety of locations along the longitudinal direction 26 as this is an aid in facilitating easy installation by the user.

(35) The motorized actuator 48 is configured to fixedly attach to the mounting plate top 56 by the set of actuator mounting apertures 46 with additional fasteners 34. The motorized actuator 48 includes a drive shaft extension 54 rotatably controllable by the motorized actuator 48. The drive shaft extension 54 is configured to extend through a portion of the set of actuator mounting apertures (i.e. the drive slot 52) and extend beyond mounting plate bottom 58 as best seen in FIG. 2.

(36) A drive lever 60 is connectable to the drive shaft extension 54. For example, the drive lever 60 can include a non-rotatable key aperture 62. In FIG. 4 the key aperture 62 is shown as a rectangular hole. The drive shaft extension 54 would then include a similarly shaped insertable key 64. Here, the insertable key 64 would also be rectangularly shaped to fit non-rotatably within the key aperture 62. In this way the drive shaft extension is fixedly connectable to the drive lever 60. This may be best seen in FIG. 5 which also shows a washer 68 and a fastener 34 that help hold the drive lever 60 to the drive shaft extension 54. It will be understood by those skilled in the art that a variety of methods and designs could be utilized to connect the drive lever 60 to the drive shaft extension 54 as this teaching is not limited just the exact structure shown and taught herein. Furthermore, the drive shaft extension 54 may also be an optional feature and may be eliminated or integrated as one structure combined with the drive lever 60.

(37) All of the various adjustability of the components to the retrofit motorized actuator assembly 30 is designed and configured such that the user is able to attach the retrofit motorized actuator assembly such that the drive lever 60 is disposed directly above and adjacent to the valve handle 16 with the axis of rotation of the valve handle 24 aligning with the axis of rotation 68 of the drive shaft extension 54. In other words, the drive lever 60 is configured to be adjacently disposed in parallel to the cantilevered valve handle 16.

(38) As shown in FIGS. 7A and 7B, to further aid in placement of the drive lever 60, the drive shaft extension 54 can be raised or lowered with the use of a collar 70 and a fastener 34 or the like. The motorized actuator 48 rotates the collar 70. Then the drive shaft extension 54 is able to move up and down within the collar 70. The fastener 34 is then used to lock the collar 70 and drive shaft extension 54 together such that they rotate as one unit. FIG. 7A shows the drive shaft extension 54 raised while FIG. 7B shows the drive shaft extension 54 lowered. It will be understood by those skilled in the art that many methods or structures could be used to allow the drive shaft extension 54 to be raised or lowered as this disclosure is not to be limited just to the exact embodiment shown and taught herein.

(39) Referring back to FIG. 2 a quick connect clamp 72 is configured to fixedly attach together both the drive lever 60 and the cantilevered valve handle 16. The quick connect clamp 72 is configured to be attachable and removable with just the use of a user's hands, meaning no special tools or devices are necessary to install or remove the quick connect clamp 72.

(40) An advantage of this novel design is that the whole assembly for the retrofit motorized actuator assembly can be installed without having to cut, drill or in any way modify or tamper with the prior art fluid valve 10. Another advantage of this novel design is that the prior art fluid valve 10 can now be remotely opened or closed depending on various circumstances. For instance, the motorized actuator 48 is electrically operated and controlled. If a leak is detected through the use of an automatic sensing means installed in the building, a signal can be sent to the motorized actuator 48 and the flow of fluid through the fluid pipe 12 shut off. However, in some emergencies power or communication can be lost or the device controlling the motor malfunction. In these situations or emergencies, the quick connect clamp can be easily and quickly removed such that the valve handle 16 can be manually moved by the user without the aid of the motorized actuator 48.

(41) The quick connect clamp 72 can take many forms, designs or configurations known to those skilled in the art after reading this disclosure. FIGS. 8A and 8B show a simple embodiment of a sleeve 72a. The sleeve 72a is simple sleeve slipped over the drive lever 60 and valve handle 16 thereby locking them together.

(42) FIGS. 9A and 9B are a similar embodiment to FIGS. 8 but now includes a spring loaded detent or flexure detent 74 integrated into the quick connect clamp 72b that is configured to releasably engage apertures or recesses 76 disposed within the drive lever 60.

(43) FIGS. 10A and 10B show a U-shaped quick connect clamp 72c that can be simply slid from one side and then locked on the opposite side with a pin 78. The pin 78 can also include a button 80 that releases a detent 74.

(44) FIGS. 11A and 11 B show a hinged quick connect clamp 72d that pivots about a hinge 82 and then uses a fastener 84 to lock the two halves together. In this embodiment, the fastener 84 has a winged end 86 such that it can easily be rotated by the user to engage or disengage without the use of tools or other devices.

(45) FIGS. 12A and 12B show a flexure-type quick connect clamp 72e that can be pushed over both the drive lever 60 and valve handle 16. The slanted opening 88 helps to aid in installation and the edge 90 helps to hold it onto the valve handle 16. Then the ribs 92 can be used to help flex the structure apart when trying to remove the flexure-type quick connect clamp 72e.

(46) FIG. 13 shows a different embodiment of the quick connect clamp and drive lever where the two functionalities have been combined. The drive lever 60 has now been broken into two parts; drive lever 60a and drive lever 60b. A slot 94 is disposed through both ends of the drive levers, drive lever 60a having slot 94a and drive lever 60b having slot 94b. In use, the drive lever 60a is permanently installed onto the drive shaft extension 54. Similarly, the drive lever 60b is permanently installed onto the valve handle 16 through various clamps or known techniques. A slotted pin 96 is then inserted through both slots 94 as shown in FIGS. 14A and 14B. Due to the non-circular shape of the slotted pin 96, both drive levers 60a and 60b move as one. The slotted pin 96 doesn't fall through because the slotted pin head 98 is larger in width than the slot 94. When a user wants to disengage drive lever 60a from 60b, the user simply pushes the slotted pin 96 upward and pops it from the slots 94. In this way, the user can then manually grasp the valve handle 16 and either open or close the valve portion 14.

(47) FIG. 15 is a simplified representation of FIG. 2 now showing the various motions of adjustability. Both the first pipe clamp 32a and pipe clamp 32b can move together in movement M1 where they can be positioned along the fluid pipe 12. Due the slots 46b on the mounting plate 44, the second pipe clamp 32b can also move in movement M2 to allow for various tolerance variances. The adjustable brackets 42a and 42b are able to be raised or lowered in movement M3 with respect to the pipe clamps 32. The motorized actuator 48 can also be moved in movement M4 due to the actuator mounting apertures 50 and drive slot 52 in the mounting plate 44. Finally, the drive shaft extension 54 can also be raised or lowered in movement M5 with respect to the motorized actuator 48. It will also be understood by those skilled in the art that some or all of the adjustability of the motions M1-M5 can be eliminated and the present invention still function appropriately. For example, the various clamps and brackets can be formed from one rigid structure that is configured to match a particular prior art fluid valve 10. Then, in a similar manner as discussed previously the quick connect clamp 72 would still be used to couple or decouple the drive lever 60 and valve handle 16.

(48) Another exemplary embodiment of the present invention is shown in FIGS. 16 and 17. A set of springs 100 are disposed between the motorized actuator 48 and the mounting plate 44. This forces the motorized actuator upward. At the same time the drive shaft extension 54 has been modified to have a middle portion 102 that is cylindrically shaped. The insertable key 64 is still located at the distal end of the drive shaft extension. In normal use the insertable key 64 is engaged into the key aperture 62 of the drive lever 60. If a user wants to disengage the drive shaft extension 54 from the driver lever 60, the user presses down on the motorized actuator 48 and this causes the insertable key 64 to pass through the key aperture 62 such that now the cylindrical portion 102 is disposed within the key aperture 62. Because the cylindrical portion is configured not to rotatably engage the drive lever, a user is able to rotate the valve handle 16 along with the drive lever 60.

(49) It will be understood by those skilled in the art that many configurations of key shapes for the drive lever and drive shaft extension can be designed to engage and disengage such that this teaching is not limited to the specific design shown and taught herein, but is for illustrative purposes.

(50) Furthermore, in this embodiment the compression springs are conveniently placed around the fasteners 34. However, the springs could be placed elsewhere and also take other forms. Therefore, the general concept is taught herein of creating a bias or force through springs, magnets, flexures or other force inducing structures to raise the motorized actuator such that a user can press downward to release the drive shaft extension and the drive lever. For example, the mounting plate 44 can be cut and bent such that it creates a flexible flexure that biases the motorized actuator in a higher position in normal use. Then when a user presses down on the motorized actuator the flexure flexes and disengages the drive shaft extension from the drive lever. It will be also understood that one skilled in the art could configure the motorized actuator to be raised to release the drive shaft extension from the drive lever rather being pushed downward.

(51) FIG. 18 is a perspective view of yet another embodiment of the present invention where now an elastic band 104 is used to couple the drive shaft extension 54 to the valve handle 16. FIG. 19 is an exploded perspective view of the structure of FIG. 18. In these views, an upper bracket 106 is placed above the drive lever 60. The upper bracket 106 has notches 110 and apertures 76 that match the apertures 76 on the drive lever 60. A lower bracket 108 is placed below the valve handle 16. An elastic band 104 is captured by the notches 110 on the lower bracket 108 as the elastic band is wrapper above and over the upper bracket 106 and also captured by the notches 110 on the upper bracket 106. Pins 112 are placed through the apertures 76 on both the upper bracket 106 and the drive lever 60. The upper and lower brackets can then capture and connect the drive lever 60 and the valve handle 16 such that they move together. Then, in case of an emergency, all that is needed from the user is to unhook the elastic band 104 and the drive lever 60 and valve handle 16 can be separately moved.

(52) Although several embodiments have been described in detail for purposes of illustration, various modifications may be made to each without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
