DETAILED DESCRIPTION OF THE PREFERRED

Embodiments of the Invention

[0029] Referring now to the system 10 herein in the depictions of FIGS. 1-5, there is seen in FIG. 1 an exemplar of the components of the system 10 herein. As shown, a battery powered saw 12 is operatively engaged to a distal end of an insulated pole 14 which is preferably telescopic in configuration. The pole 14 need not be part of the system 10 herein, and the saw 12 may be provided in a configuration adapted to removably engage to the distal end of a conventional insulated pole 14. However, the pole 14 must be configured to removably engage to a mount connected to the housing of the saw and is, preferably, radially configured so the angle between the two may be changed and fixed, as needed.

[0030] The removable engagement 16 (FIG. 2), preferably, provides for an angular adjustment of the saw 12 relative to the axis of the pole 14. By angular adjustment is meant that an angle of the saw cutting blade 18 of the saw can be fixed when the saw 12 is in a removable engagement 16 to the pole 14 but can be changed to another angle by changing the position of the pole mount 26 in its engagement with the mount 24 engaged to or projecting from the housing 22 of the saw.

[0031] The mount 26, shown in FIG. 1, may include the plurality of radially positioned openings 25, such as in FIG. 4, or may be configured, such as in FIG. 5, wherein a component, such as the hook component 37, is engaged to the mount 24 or 39 to provide the radially positioned openings to engage over the projections 27 extending from the pole mount 26. Of course, the projections 27 and openings 25 may be reversed in position or replaced with other connections which will provide the formation of an adjustable fixed angled connection between the saw and the pole 14.

[0032] By adjustable fixed angled connection is meant that the pole engagement to the housing 22 of the saw will form a fixed angle of the axis of the saw cutting blade 18 relative to the axis of the pole 14, which holds under force but which can be changed by repositioning the connection engaged to the housing 22 and the pole mount 26 connection. As noted, radially positioned projections 27, which will slide into complimentary spaced radially positioned openings 25, provide the current preferred adjustable fixed angled connection.

[0033] As shown in FIG. 1, the saw 12 has an electric power source in the form of a removable battery 20 which is engageable with the housing 22 holding the battery powered saw blade 18. It is preferred that this battery 20 can be removed and replaced without disengaging the saw 12 from the pole 14.

[0034] Also shown in FIG. 1 are a video camera 19 which will wirelessly communicate a video view of the saw cutting blade 18 and areas adjacent it to a remote display 21 which may be mounted at the grasping end of the pole 14 or on the remote control 34. The camera 19 and display 21, if provided, will allow the user to view and position the saw cutting blade 18 properly, relative to a branch or the like being cut which would also be viewable in the display 21 from the ground, remotely. Touching an activation control button 38 will cause the remote control 34 to transmit a wireless signal to the actuator 30 causing it to change to the connected state, where electric power from the battery 20 is connected to the motor 33 to thereby cause the saw blade 18 to move and cut.

[0035] Optionally, the remote control 34 and display 21 could be a smartphone which has wireless capability and software operating to the task of communicating a wireless signal to the actuator 30 which causes it to change from the disconnected state to a connected state which connects electric power from the battery 20 to the motor 33 to move the saw blade 18 to cut. If a smartphone is used, an app will interface with the remote actuator 30 to allow the user to employ the display screen and/or keypad on the smartphone to control the saw and to view video from the camera 19. A light 23 may be included with the camera 19 to illuminate both the saw cutting blade 18 and area around it.

[0036] In all modes of the system 10, a remote actuator 30 is operatively positioned in or with the housing 22, as shown in FIGS. 3-4, which operates upon receiving a wireless transmission to switch and communicate electric power from the battery 20 to the motor 33 powering the cutting blade of the saw 12. The remote actuator 30 has an antenna and circuitry which is activated by the wireless signal from a remote control 34. Upon receipt of a signal, the actuator 30 will cause power from the battery 20 to connect with the motor 33, thereby causing the saw to cut. Particularly preferred is a wireless remote control 34 which is configured for an engagement to the pole 14 at a position on the end held by the user. This allows the employment of both hands of the user to manipulate the pole 14 while still being able actuate the saw as needed.

[0037] As shown in FIG. 3 but applicable to all modes of the device 10 herein, a connector 36 is preferably engaged on the remote control 34 which will hold it operatively engaged upon the pole 14. Such may be a clip or clamp or other conventional connector 36 which will hold the remote control 34 in place on the pole 14, whereby the user may operate the activation button 38 which will activate the remote control 34 to send a wireless signal to the actuator 30 to cause it to switch and to connect the battery 20 operatively to the motor 33 to energize the saw 12 and cause the saw cutting blade 18 to move under power of the electric motor 33. The saw blade 18, thus, has a cutting mode or operation wherein the cutting blade 18 moves or reciprocates when powered by the electric motor 33. The cutting blade 18, currently preferred, is a chainsaw type cutting blade 18 as it will quickly cut through branches and the like. However, it could also be a reciprocating blade.

[0038] In FIG. 2 is shown an enlarged view of a preferred mode of removable engagement 16 of the housing 22 of the saw to the pole 14, as noted above. As shown, one of the housing mount 24 or pole mount 26 has the radially positioned openings 25 in it. The pole mount 26, engaged to the distal end of the pole 14, will have projections 27 thereon which are radially positioned to align with and engage with the radially positioned openings 25. Once the openings 25 are positioned over the projections 27, a nut 29 or the like can be engaged upon a center mount, such as a threaded member 31, to hold the housing mount 24 and housing in the chosen fixed angled engagement with the pole 14. Because the openings 25 radially align with the projections 27, rotation of the component with the openings 25, during engagement to the projections 27, allows for a change in the fixed angle of the housing 22 and the saw cutting blade 18 relative to the axis of the pole 14. As noted herein, the projections 27 and openings 25 may be reversed as to placement where the openings are on the pole mount 26 and the projections 27 are on the mount 24.

[0039] As also noted, the housing 22 of a the saw 12 can be configured such that it has a projecting housing mount 24 which is configured for removable engagement to a pole mount 26 located at the distal end of a pole 12. The projecting housing mount 24 may include a hook component 37 or in the preferred mode of the device, the hook component 37 is removably engageable to the formed housing mount 24 which allows for replacement and a flipping of the hook component 37 to place it toward the front or the rear of the saw.

[0040] In modes of the device where a first mount 24 is located on the lower edge and a second mount 39 projects from a top or upper edge of the housing 22 opposite the lower edge, the removably engageable hook 37 is especially preferred in that it may be repositioned, as may the housing 22, to place the saw cutting blade 18 at an inclining or declining angle depending on which of the first mount 24 or second mount 39 is used to engage the pole 14 in the fixed angled mount.

[0041] Alternatively, as depicted, for example in FIG. 3, the system 10 can also be provided with a secondary housing 28 to allow the use of an existing saw. This secondary housing 28 may be formed of non conductive material and sized and contoured to surround and engage with the exterior of an existing saw housing 22 of an existing electric saw. In this mode, the secondary housing 28 would be provided with an interior or other surface configuration which is complimentary to the exterior mating surface of the housing 28 of an existing saw. The secondary housing 28 will be connected to an existing saw, and then the mount 24, positioned on the secondary housing 28, will be engaged with the complimentary pole mount 26 of the chosen insulated pole 14. The mount 24 on the secondary housing 28 is preferably configured to engage with a hook component 37, also.

[0042] In this mode of the system 10, a plurality of different secondary housings 28 can be provided with each of the plurality configured for operative engagement to the exterior of a specific existing powered saw. This mode of the system 10 is adapted for employment for users already owning electric saws. The secondary housing 28, preferably, once operatively connected to a saw, will provide for insertion of a battery 20 on the existing saw or secondary housing 28 without the need to remove the pole 14.

[0043] Shown in FIG. 4 is an especially preferred mode of the device 10 herein in a sectional view of the housing 22 and showing the internal components which operate and actuate the motor and saw. Also shown are a first housing mount 24 and second housing mount 39. Both of which are configured with radial openings for a varying angled engagement with the pole mount 26 engaged to the pole 14. Hook components 37, such as in FIG. 5, are engageable to either the first mount 24 or second or upper mount 39 so that the hook component 37 may be included in a mount of the pole 14 to either the upper or lower edge of the housing 22.

[0044] In FIG. 5 is shown another preferred device 10 showing a sectional view and the exterior of the casing 22 and showing a first or lower housing mount 24 positioned on a bottom edge of the housing 22 and second mount 39 positioned on an opposite top edge of the housing 22. Both of the mounts are configured for engagement to a hook component 37 which also has the mating openings 25 or projections 27 thereon to allow for engaging the pole 14 to the housing 22 at varying angles which are held fixed by the openings engaged to the projections, as noted above. Other mounts may be employed if they provide for changing the angle of the housing 22 relative to the axis of the pole 14, so long as such mounts will strongly hold at a chosen angle.

[0045] The hook components 27 are also removably engageable so they may be replaced and may be flipped in position between a forward located position, as in FIG. 1, and a rearward position with the hook extending toward the battery 20, as in FIG. 2.

[0046] In a method of the system 10 herein, a user will removably engage the mount 24 located on a housing 22 of a saw 12 or upon a secondary housing 28 engaged to a housing 22 of a saw to a pole mount 26 at the distal end of an insulated pole 14. The angle of the axis of the saw cutting blade 18 can be adjusted during the engagement of the saw to the pole mount 26, as noted above. The hook component 37 will also be positioned in a forward or rearward positioning. A nut 29 or other engageable connector will be tightened to hold the mount 24 to the pole mount 26 at the chosen angle and to hold the hook component 37 to the housing 22 or to the pole connector. The user will then extend the pole 14, which has telescopic sections 11 (FIG. 2), to position the distal end of the pole 14 and the saw thereon at a work position. Once operatively positioned, the user will actuate the remote control 34 to energize the saw to cause the saw cutting blade 18 to cut the chosen branch or the like.

[0047] While all of the fundamental characteristics and features of the disclosed insulated pole electric saw engagement system and method have been shown and described herein, with reference to particular embodiments thereof, a latitude of modification, various changes and substitutions are intended in the foregoing disclosure and it will be apparent that in some instances, some features of the invention may be employed without a corresponding use of other features without departing from the scope of the invention as set forth. It should also be understood that various substitutions, modifications, and variations may be made by those skilled in the art without departing from the spirit or scope of the invention. Consequently, all such modifications and variations and substitutions as would occur to those skilled in the art, are considered as included within the scope of the invention as defined by the following claims.
