Detailed Description of the Preferred Embodiment [Para 221 The present invention a quick release mechanism is shown generally as 100 in the Figures. Figures 1 and 2 in particular show in schematic fashion the quick release mechanism 100 in the detached position 202 shown in Figure 1, and in the attached position 210 shown in Figure 2. Figure 3 through 7 shows the sequence for placing the quick release mechanism 100 from the detached position 202 to the attached position 210 in the sequence as shown in Figures 3 through 7 inclusively.
[Para 23] Quick release mechanism 100 includes the following major components namely frame 104, base 150 and a latch 180.
[Para 24] Frame 104 normally includes first member 106, second member 108, lip 114, guide aperture 116 and hinge slot 118.
[Para 25] Base 150 includes a slot 152, planar surface 154, catch aperture 156, and catch flange 158.
[Para 26] Latch 180 includes a push pad 182 connected to a hinge member 184, a guide member 188, and also a catch 190. Frame 104 may include a frame top portion 112 as shown schematically in Figure 1. Note hinge member 184 and guide member 188 are spaced from each other and preferably oriented parallel to each other. Hinge member 184 connected at one end of push pad 182 and guide member 188 connected to the other end of push pad 182 form in cross sectional view a roughly U shaped configuration.
[Para 27] Frame 104 and frame top portion 112 are normally integrally part of a connecting portion 303, wherein the connecting portion 303 together with one or more frames 104 in general terms forms a universal attachment body 906. The drawings show two examples of universal attachment body namely handle 302, and pole sanding body 402. These are only two examples of hand tools showing application of the quick release mechanism 100. Quick release mechanism 100 could also be applied to a number of other hand tools which would benefit from having a quick release portion of the tool.
[Para 28] Frame 104 together with connecting portion 303 may form handle 302 as shown in Figure 8, wherein two quick release mechanisms are shown deployed in hand sander 300 having two bases 150 connected with a universal platform 902 which in this case is simply platform 159, wherein platform together with bases 150 form a sanding pad 169. Optionally sanding pad 169 includes sand paper clamps 305. A person skilled in the art will recognize this as a hand sander 300, wherein sand paper is spanned across the bottom of sanding pad 169 and clamped by clamps 305 in position. Universal attachment body 906 which in this example is handle 302 can be easily and quickly attached or detached to universal platform 902 which in this example is sanding pad 169 using quick release mechanism 100.
[Para 29] Frames 104 can also be connected together with connecting portion 303 which together forms a universal attachment body 906 which in this example is a pole sanding body 402 as shown in Figure 13. In this example as in the last two bases 150 are connected with a universal platform 902 which in this case is simply platform 159, wherein platform together with bases 150 forms a sanding pad 169. Optionally sanding pad 169 includes sand paper clamps 305. A person skilled in the art will recognize this as a pole sander 400, wherein sand paper is spanned across the bottom of sanding pad 169 and clamped by clamps 305 in position. Figure 13 is a schematic side elevational view of a typical pole sander 400 also showing a pole attachment 404 for receiving a threaded broom handle therein, together with pole sanding body 402 having two quick release mechanisms 100, wherein pole sanding body 402 is detachably mounted onto sanding pad 169 with two quick release mechanisms 100. Pole sanding body 402 can be quickly and easily attached or detached from sanding pad 169 using the quick release mechanisms 100 as shown in Figures 13 through 17.
[Para 30] Figures 18 through 22 show details of the latch 180 as described herein.
[Para 31] Figures 23 to 33 show corner sander 930 including frames 104 connected together with connecting portion 303 thereby forming a universal attac.hment body 906 which as shown in Figure 32 is handle 302 or as shown in Figure 33 is pole sanding body 402. Bases 150 are connected together with platform 161 thereby forming universal platform 902 which in turn attaches to corner sanding base 904 which in turn is connected to sand paper 905. In this example universal platform 902 can in turn be attached to a number of different elements one example given here being a corner sanding base 904.
In Use [Para 32] Quick release mechanism 100 can be applied to hand tools having a geometry where it is desirable to attach two elements together generally for example a universal attachment body 906 to a universal platform 902 wherein the frame 104 is connected to or integrally part of the universal attachment body 906 and a base 150 is connected to or integrally part of universal platform 902. In this description we show specific examples of how quick release mechanisms 100 can be applied. In one example quick release mechanisms 100 are used to attach for example a manual handle shown as handle 302 and/or a pole sanding body shown as 402 to a platform 159. These examples are both in the field of sanding, however, there is no reason why base 150 could not perform some other function such as a float or other tool which requires the quick release mechanism for attachment of handles and/or other elements. It is not intended that the present invention be limited to sanding tools and equipment, but rather the quick release mechanism 100 can be adapted to a multitude of different hand tools wherein it is desirable to have a mechanism for quickly attaching and detaching a universal attachment body 906 to a universal platform 902.
[Para 33] By way of example only, for providing examples of how the quick release mechanism 100 can be applied to various applications, we are showing quick release mechanism 100 deployed in the field of sanding.
[Para 34] Quick release mechanism as indicated above includes a base 150, latch 180 and a frame 104. The purpose of quick release mechanism 100 is to quickly and easily attach and detach frame 104 to base 150. Frame 104 and base 150 can be part of many different configurations, examples of which are shown in this application.
[Para 35] Frame 104 will normally include a first member 106 spaced from a second member 108 which as shown in Figures 1 and 2 are vertical, however it is not necessary that the first member 106 and second member 108 be vertical. First member 106 of frame 104 includes an integrally connected a lip 114 which fits into slot 152 defined in base 150. Slot flange 160 together with base 150 defines slot 152 for cooperatively and slidably receiving lip 114 within slot 152. Second member 108 has defined therein a hinge slot 118 and a guide aperture 116 for receiving hinge member 184 within hinge slot 118 and guide member 188 within guide aperture 116.
Latch 180 is slidably received into second member 108 as depicted in Figure 1, wherein locking tab 186 defined on one distal end of hinge member 184, positively locks latch 180 into frame 104. Latch 180 also includes a push pad 182 which when finger pressure is applied to push pad 182, the entire latch 180 pivots about hinge axis 130 as shown in Figure 1. In this manner catch 190 can be moved laterally along lateral direction 132 by applying finger pressure to push pad 182. Catch 190 is normally in the locked position as shown in Figure 2, however it can be urged laterally along lateral direction 132, thereby allowing it to pass past the catch flange and pass through catch aperture 156 defined in base 150 for detaching frame 104 from base 150. Catch 190 latches onto catch flange 158 defined in base 150, when in the attached position 210. As finger pressure is applied to push pad 182, guide member 188 slightly moves laterally within guide aperture 116 and latch 180 pivots or flexes about hinge axis 130. The sequence for attaching frame 104 from the detached position 202 to the attached position 210 is shown in Figures 3 through 7.
Figure 3 shows the frame 104 and base 150 in the detached position 202.
[Para 36] Referring now to Figure 4, firstly lip 114 is slidably received within slot 152 until first member 106 abuts onto slot flange 160 as shown in Figure
[Para 20] A pole sanding frame with a detachable quick release pole sanding body, the pole sanding frame comprising two spaced apart quick release mechanisms wherein the frames of each quick release mechanism attached to a connecting portion wherein the frames together with the connecting portion defining a unitary pole sanding body, and wherein the bases of each quick release mechanism attached to a platform wherein the bases together with the platform defining a unitary sanding pad, wherein the pole sanding body and the sanding pad moveable between an attached position and detached position, wherein in the attached position the pole sanding body together with the sanding pad being a pole sanding frame.

Frame 104 may include a frame top portion 112 as shown schematically in Figure 1. Note hinge member 184 and guide member 188 are spaced from each other and preferably oriented parallel to each other. Hinge member 184 connected at one end of push pad 182 and guide member 188 connected to the other end of push pad 182 form in cross sectional view a roughly U shaped configuration.
[Para 27] Frame 104 and frame top portion 112 are normally integrally part of a connecting portion 303, wherein the connecting portion 303 together with one or more frames 104 in general terms forms a universal attachment body 906. The drawings show two examples of universal attachment body namely handle 302, and pole sanding body 402. These are only two examples of hand tools showing application of the quick release mechanism 100. Quick release mechanism 100 could also be applied to a number of other hand tools which would benefit from having a quick release portion of the tool.
[Para 28] Frame 104 together with connecting portion 303 may form handle 302 as shown in Figure 8, wherein two quick release mechanisms are shown deployed in hand sander 300 having two bases 150 connected with a universal platform 902 which in this case is simply platform 159, wherein platform together with bases 150 form a sanding pad 169. Optionally sanding pad 169 includes sand paper clamps 305. A person skilled in the art will recognize this as a hand sander 300, wherein sand paper is spanned across the bottom of sanding pad 169 and clamped by clamps 305 in position. Universal attachment body 906 which in this example is handle 302 can be easily and quickly attached or detached to universal platform 902 which in this example is sanding pad 169 using quick release mechanism 100.
[Para 29] Frames 104 can also be connected together with connecting portion 303 which together forms a universal attachment body 906 which in this example is a pole sanding body 402 as shown in Figure 13. In this example as in the last two bases 150 are connected with a universal platform 902 which in this case is simply platform 159, wherein platform together with bases 150 forms a sanding pad 169. Optionally sanding pad 169 includes sand paper clamps 305. A person skilled in the art will recognize this as a pole sander 400, wherein sand paper is spanned across the bottom of sanding pad 169 and clamped by clamps 305 in position. Figure 13 is a schematic side elevational view of a typical pole sander 400 also showing a pole attachment 404 for receiving a threaded broom handle therein, together with pole sanding body 402 having two quick release mechanisms 100, wherein pole sanding body 402 is detachably mounted onto sanding pad 169 with two quick release mechanisms 100. Pole sanding body 402 can be quickly and easily attached or detached from sanding pad 169 using the quick release mechanisms 100 as shown in Figures 13 through 17.
[Para 30] Figures 18 through 22 show details of the latch 180 as described herein.
[Para 31] Figures 23 to 33 show corner sander 930 including frames 104 connected together with connecting portion 303 thereby forming a universal attac.hment body 906 which as shown in Figure 32 is handle 302 or as shown in Figure 33 is pole sanding body 402. Bases 150 are connected together with platform 161 thereby forming universal platform 902 which in turn attaches to corner sanding base 904 which in turn is connected to sand paper 905. In this example universal platform 902 can in turn be attached to a number of different elements one example given here being a corner sanding base 904.
In Use [Para 32] Quick release mechanism 100 can be applied to hand tools having a geometry where it is desirable to attach two elements together generally for example a universal attachment body 906 to a universal platform 902 wherein the frame 104 is connected to or integrally part of the universal attachment body 906 and a base 150 is connected to or integrally part of universal platform 902. In this description we show specific examples of how quick release mechanisms 100 can be applied. In one example quick release mechanisms 100 are used to attach for example a manual handle shown as handle 302 and/or a pole sanding body shown as 402 to a platform 159. These examples are both in the field of sanding, however, there is no reason why base 150 could not perform some other function such as a float or other tool which requires the quick release mechanism for attachment of handles and/or other elements. It is not intended that the present invention be limited to sanding tools and equipment, but rather the quick release mechanism 100 can be adapted to a multitude of different hand tools wherein it is desirable to have a mechanism for quickly attaching and detaching a universal attachment body 906 to a universal platform 902.
[Para 33] By way of example only, for providing examples of how the quick release mechanism 100 can be applied to various applications, we are showing quick release mechanism 100 deployed in the field of sanding.
[Para 34] Quick release mechanism as indicated above includes a base 150, latch 180 and a frame 104. The purpose of quick release mechanism 100 is to quickly and easily attach and detach frame 104 to base 150. Frame 104 and base 150 can be part of many different configurations, examples of which are shown in this application.
[Para 35] Frame 104 will normally include a first member 106 spaced from a second member 108 which as shown in Figures 1 and 2 are vertical, however it is not necessary that the first member 106 and second member 108 be vertical. First member 106 of frame 104 includes an integrally connected a lip 114 which fits into slot 152 defined in base 150. Slot flange 160 together with base 150 defines slot 152 for cooperatively and slidably receiving lip 114 within slot 152. Second member 108 has defined therein a hinge slot 118 and a guide aperture 116 for receiving hinge member 184 within hinge slot 118 and guide member 188 within guide aperture 116.
Latch 180 is slidably received into second member 108 as depicted in Figure 1, wherein locking tab 186 defined on one distal end of hinge member 184, positively locks latch 180 into frame 104. Latch 180 also includes a push pad 182 which when finger pressure is applied to push pad 182, the entire latch 180 pivots about hinge axis 130 as shown in Figure 1. In this manner catch 190 can be moved laterally along lateral direction 132 by applying finger pressure to push pad 182. Catch 190 is normally in the locked position as shown in Figure 2, however it can be urged laterally along lateral direction 132, thereby allowing it to pass past the catch flange and pass through catch aperture 156 defined in base 150 for detaching frame 104 from base 150. Catch 190 latches onto catch flange 158 defined in base 150, when in the attached position 210. As finger pressure is applied to push pad 182, guide member 188 slightly moves laterally within guide aperture 116 and latch 180 pivots or flexes about hinge axis 130. The sequence for attaching frame 104 from the detached position 202 to the attached position 210 is shown in Figures 3 through 7.
Figure 3 shows the frame 104 and base 150 in the detached position 202.
[Para 36] Referring now to Figure 4, firstly lip 114 is slidably received within slot 152 until first member 106 abuts onto slot flange 160 as shown in Figure
5. Figure 4 is the first attachment step 204, whereas Figure 5 is the second attachment step 206.
[Para 37] Referring now to Figure 6 which is the third attachment step.
Finger pressure maybe applied to push pad 182, wherein catch 190 is moved laterally such that it is able to freely pass through catch aperture 156 defined by catch flange 158 and base 150. Catch 190 will automatically be moved laterally into catch aperture 156, when frame 104 is urged downwardly onto base 150.
Therefore it is optional to apply finger pressure to push pad 182 when attac.hing frame 104 to base 105. By applying finger pressure to push pad 182, the entire latch mechanism 180 pivots about hinge axis 130, thereby allowing catch 190 to clear through catch aperture 156. Once the catch 190 is clear through catch aperture 156, pressure can be released from push pad 182 and natural resiliency of latch 180, places catch 190 in the normally closed or attac:hed position 210 as shown in Figure 7, wherein catch makes positive contact with catch flange 158, thereby preventing frame 104 from being accidentally detached from base 150. During the attachment process, frame 104 is urged downwardly onto base 150. Inclined surface 191 will contact catch flange 158 and move catch 190 laterally under the downward pressure placed on frame 104.
[Para 38] In order to detach frame 104 from base 150, the reverse of the procedure just described above is applied, namely Figure 7 through 3 in reverse order is initiated in order to detach frame 104 from base 150. One must apply finger pressure to push pad 182 in order to detach frame 104 from base 150.
[Para 39] Figures 8 through 12 show a hand sander 300 with two quick release mechanisms 100 deployed therein. In this example, frame 104 is integrally part of handle 302 as shown in drawing Figures 8 through 12..
[Para 40] A second example of how quick release mechanism 100 can be deployed in a pole sander is shown in Figures 13 through 17. Pole sander 400 includes a pole attachment 404 and a pole sanding body 402. Frame 104 is integrally part of pole sanding body 402 as shown in Figure 13 through 17. A
person skilled in the art will note that a piece of flat sand paper (not shown) can be stretched across the bottom of sanding pad 169 and clamped in by clamps 305. Using the steps described above for attachment and detachment of frame 104 from base 150, one can easily attach pole sanding body 402 onto sanding pad 169. Pole sanding body 402 together with attached sanding pad 169 defining a pole sanding frame 920. Pole sanding frame 920 together with a pole attachment 404 defining a pole sander 400.
[Para 41] A person skilled in the art will recognize that the same base 150 can be used for pole sander 400 and also for the hand sander 300. In this case handle 302 can be quickly attached or detached from sanding pad 169 and pole sanding body 402 together with a pole attachment 404 can be quickly attac:hed to the same sanding pad 169 and/or detached from that same sanding pad 169 quickly and easily. Therefore the same sanding pad 169 can be used as either a hand sander 300 and/or a pole sander 400 as depicted.
[Para 42] The details of the latch 180 are shown in Figures 18 through 22, wherein one example of how latch 180 could be designed is shown. Kindly note that the geometry, of for example the guide member and/or the hinge member and/or the push pad and/or for that matter the catch can be altered somewhat and yet produce the same effect. For example the guide member 188 may be rod like and/or be flat. Similarly the hinge member 184 may also take on various shapes provided that the same function is maintained.
[Para 43] It should be apparent to persons skilled in the arts that various modifications and adaptation of this structure described above are possible without departure from the spirit of the invention the scope of which defined in the appended claim.

[Para 37] Referring now to Figure 6 which is the third attachment step.
Finger pressure maybe applied to push pad 182, wherein catch 190 is moved laterally such that it is able to freely pass through catch aperture 156 defined by catch flange 158 and base 150. Catch 190 will automatically be moved laterally into catch aperture 156, when frame 104 is urged downwardly onto base 150.
Therefore it is optional to apply finger pressure to push pad 182 when attac.hing frame 104 to base 105. By applying finger pressure to push pad 182, the entire latch mechanism 180 pivots about hinge axis 130, thereby allowing catch 190 to clear through catch aperture 156. Once the catch 190 is clear through catch aperture 156, pressure can be released from push pad 182 and natural resiliency of latch 180, places catch 190 in the normally closed or attac:hed position 210 as shown in Figure 7, wherein catch makes positive contact with catch flange 158, thereby preventing frame 104 from being accidentally detached from base 150. During the attachment process, frame 104 is urged downwardly onto base 150. Inclined surface 191 will contact catch flange 158 and move catch 190 laterally under the downward pressure placed on frame 104.
[Para 38] In order to detach frame 104 from base 150, the reverse of the procedure just described above is applied, namely Figure 7 through 3 in reverse order is initiated in order to detach frame 104 from base 150. One must apply finger pressure to push pad 182 in order to detach frame 104 from base 150.
[Para 39] Figures 8 through 12 show a hand sander 300 with two quick release mechanisms 100 deployed therein. In this example, frame 104 is integrally part of handle 302 as shown in drawing Figures 8 through 12..
[Para 40] A second example of how quick release mechanism 100 can be deployed in a pole sander is shown in Figures 13 through 17. Pole sander 400 includes a pole attachment 404 and a pole sanding body 402. Frame 104 is integrally part of pole sanding body 402 as shown in Figure 13 through 17. A
person skilled in the art will note that a piece of flat sand paper (not shown) can be stretched across the bottom of sanding pad 169 and clamped in by clamps 305. Using the steps described above for attachment and detachment of frame 104 from base 150, one can easily attach pole sanding body 402 onto sanding pad 169. Pole sanding body 402 together with attached sanding pad 169 defining a pole sanding frame 920. Pole sanding frame 920 together with a pole attachment 404 defining a pole sander 400.
[Para 41] A person skilled in the art will recognize that the same base 150 can be used for pole sander 400 and also for the hand sander 300. In this case handle 302 can be quickly attached or detached from sanding pad 169 and pole sanding body 402 together with a pole attachment 404 can be quickly attac:hed to the same sanding pad 169 and/or detached from that same sanding pad 169 quickly and easily. Therefore the same sanding pad 169 can be used as either a hand sander 300 and/or a pole sander 400 as depicted.
[Para 42] The details of the latch 180 are shown in Figures 18 through 22, wherein one example of how latch 180 could be designed is shown. Kindly note that the geometry, of for example the guide member and/or the hinge member and/or the push pad and/or for that matter the catch can be altered somewhat and yet produce the same effect. For example the guide member 188 may be rod like and/or be flat. Similarly the hinge member 184 may also take on various shapes provided that the same function is maintained.
[Para 43] It should be apparent to persons skilled in the arts that various modifications and adaptation of this structure described above are possible without departure from the spirit of the invention the scope of which defined in the appended claim.
