DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
2 o In the following description, similar features in the drawings have been given similar reference numerals and in order to weight down the figures, some elements are not referred to in some figures if they were already identified in a precedent figure.
2 s The present invention concerns a snow tool which can be retracted when not in use for providing a relative compact form allowing an easier storage thereof. The snow tool is provided with a brush usable in longitudinal mode where the bristles of the brush are para11e1 to the brush handle or in transversal mode where the bristles of the brush are perpendicular to the brush handle. The snow tool can thus achieve 3 o the advantages of a T-shaped brush at the same time as those of a longitudinal brush. Moreover, as it will be described in more details hereinbelow, the snow tool of the present invention has means providing an automatic opening of the snow tool for offering to the user a very easy and quick operation thereof. Furthermore, the snow tool of the present invention can also be easily and quickly retracted, without the need of being dismantled. Besides, the present snow tool is simple to construct and inexpensive to manufacture.
Referring to Figures 1 and 2, there is shown a snow tool 20 according to the present invention. The snow tool 20 includes a telescopic handle 22 having first and second members 24, 26 connected in a sliding relationship and providing retracted and extended states _of the handle 22. Figure 1 shows the snow tool 20 in the 1 o retracted state while Figure 2 shows the snow tool 20 in the extended state.
Figures 3 and 4 show another snow tool 20 according to the present invention, wherein only the visual design slightly differs from the snow tool shown in Figures 1 and 2.
Referring now to Figures 5 and 6, there is shown another snow tool 20 having a visual design slightly different from the snow tool shown in the preceding Figures.
The snow tool 20 includes a pair of arms 28, 30, each having bristles 32 provided along the length thereof. An end 34, 36 of each of the arms 28, 30 is pivotally 2 o attached to the first member 24. In a preferred embodiment, a fixing element 102, as illustrated on Figures 16, can be used for conveniently mounting the arms 28, 30 on the first element 24. The snow tool 20 is also provided with means for moving the arms 28, 30 between a closed position where the arms 28, 30 extend along the handle 22 and an open position where the arms 28, 30 extend transversally to the 2 5 handle 22. Figure 1 illustrates a snow tool 20 whose arms 28, 30 extend along the handle 22 while Figure 2 illustrates the same snow tool 20 with the arms 28, extending transversally to the handle 22.
Still referring to Figures 5 and 6 and also to Figure '7, preferably, in a preferred 3 o embodiment of the present invention, the means for moving the arms 28, 30 include a collar 38 slidably mounted along the first member 24 of the handle 22 for a longitudinal motion relative to the first member 24. The means for moving the arms 28, 30 also include a pair of struts 40, 42, each having first and second extremities.
The first extremities 44, 46 are pivotally mounted on the arms 28, 30 respectively, while the second extremities 48, 50 are pivotally mounted on the collar 38.
Figures 14 and 15 respectively show a left strut 42 and a right strut 40. The means for moving the arms 28, 30 is also provided with a pair of torsion springs 52, 54 respectively connected to the second extremities 48, 50 of the struts 40, 42 for urging the arms 28, 30 in the open position.
Referring again to Figures 5 and 6 and also to Figures 8 and 12, the snow too( Z o 20 of the present invention includes first locking means for locking the first and second members 24, 26 with respect to each other in the retracted state.
Preferably, in a preferred embodiment, the first locking means include a first pair of recesses 62, 64 provided on both sides of a portion of the first member 24, distal from a rear portion fi0 of the first member 24. The first Pocking means also preferably include a U-shaped element 66 mounted on the second member 26 and having legs 68, 70 capable of cooperating with the first pair of recesses 62, 64. The U-shaped element 66 has a first locked position wherein the legs 68, 70 engage in the first pair of recesses 62, 64 for locking the handle 22 in the retracted state. The U-shaped element 66 also has an unlocked position wherein the legs 68, 70 extend out of the z o recesses for allowing movement of the first member 24 with respect to the second member 26. In this unlocked position, the legs 68, 70 are able to slide freely along the sides of the first member 24. The first locking means also preferably include a resilient means 72, which is preferably a spring, operatively connected to the U-shaped element 66 for urging the legs 68; 70 towards the side portions of the first 2 5 member 24, thereby locking the U-shaped element 68 in the first locked position when the legs 68, 70 are aligned with the first pair of recesses 62, 64. A
depression of the U-shaped element 66 by the user unlocks the U-shaped element 66.
The snow tool 20 also includes second locking means for locking the first and 3 o second members 24, 26 with respect to each other in the extended state.
Preferably, in a preferred embodiment, the second locking means include a second pair of recesses 56, 58 provided on both sides of a rear portion 60 of the first member 24.
The second locking means also preferably include a U-shaped element 66 mounted on the second member 26 and having legs 68, 70 capable of cooperating with the second pair of recesses 56, 58. The U-shaped element 66 has a second locked position wherein the legs 68, 70 engage in the second pair of recesses 56, 58 for locking the handle 22 in the extended state. The U-shaped element 66 also has an unlocked position wherein the legs 68, 70 extend out of the recesses for allowing movement of the first member 24 with respect to the second member 26. In this unlocked position, the legs 68, 70 are able to slide freely along the sides of the first member 24. The first locking means also preferably include a resilient means 72, 1 o which is preferably a spring, operatively connected to the U-shaped element 66 for urging the legs 68, 70 towards the side portions of the first member 24, thereby locking the U-shaped element 66 in the second locked position when the legs 68, 70 are aligned with the second pair of recesses 56, 58. A depression of the U-shaped element 66 by the user unlocks the U-shaped element 66.
In a preferred embodiment, the first and second locking means can be coupled together. In other words, the U-shaped element 66 has first and second positions wherein the legs 68, 70 respectively engage in the first pair of recesses 62, 64 for locking the handle 22 in the retracted state and in the second pair of recesses 56, 2 0 58 for locking the handle in the extended state. The resilient means 72, which urge the legs 68, 70 towards the side portions of the first member 24 can thereby lock the U-shaped element 66 in either one of the first and second locked positions when the legs 68, 70 are aligned with one of the pairs of recesses 62, 64 and 56, 58.
Still referring to Figures 5 and 6, the snow tool 20 also includes a compression spring 74 for urging the first and second members 24, 26 into the extended state.
Thus, when the user depresses the U-shaped element 66 and unlocks it, the compression spring 74 urges the first and second members 24, 26 into the extended state. In this case, the legs 68, 70 of the U-shaped element 66 are then aligned with 3 o the second pair of recesses 56, 58. Thus, when the user then releases the U-shaped element 66, the resilient means 72 urge the legs 68, 70 towards the side portions of the first member 24 and the legs 68, 70 of the U-shaped element 66 engage in the second pair of recesses 56, 58, thereby locking the U-shaped element 66 in the second position. The first and second members 24, 26 are then locked in the extended state. When the user depresses again the U-shaped element 66, the legs 68, 70 are released from the second pair of recesses 56, 58 and are then able to slide freely along the sides of the first member 24, thereby allowing to retract the handle 22.
Referring now to Figures 8 and 13, and again to Figures 5 and 6, the snow tool 20 is also provided with third locking means for locking the arms 28, 30 in the open 1 o position. Preferably, the third locking means include an abutting element ?6 provided on the collar 38 and a resilient raised stop 78 provided on a front portion 80 of the first member 24, capable of cooperating with the abutting element 76 of the collar 38.
The third locking means has a locked position wherein the stop 78 engage with the abutting element 76 for locking the arms 28, 30 in the open position. The third 1s locking means also preferably include a resilient tooth 90 provided on the collar 38 and capable of cooperating with the resilient raised stop 78. A depression of the resilient tooth 90 by the user unlocks the third locking means, thereby allowing to move the arms 28, 30 in the closed position. The second locking means can be provided with a push button 116 cooperating with the tooth 90 for facilitating the use 2 0 of the snow tool 20. It is to be understood that other convenient means could also be envisaged for locking the arms 28; 30 in the open position. For example; the third locking means may be provided with a recessed area provided on the front portion 80 of the first member 24. In this case, the collar 38 would be provided with a button 116 pivotally mounted thereon and provided with a projecting element extending 2 5 frontward. The projecting element would have an abutting member provided frontward the projecting element and capable of cooperating with the recessed area of the f;rst member 24. The third locking means would have a locked position wherein the abutting member engages with the recessed area for locking the arms 28, 30 in the open position. In this case, a depression of the button 116 by the user 3 o will pivotally operate the projecting element upwardly for disengaging the abutting element of the recessed area, thereby allowing to move the arms 28, 30 in the closed to position. Of course, any other convenient means known in the art could also be used and won't be further described therein.
Referring now to Figures 5, 6, 12 and 13, the snow tool 20 is also provided with fourth locking means for locking the arms 28, 30 in the closed position. In a preferred embodiment of the present invention, the fourth locking means include a first attaching element 92 provided on the U-shaped element 66 and a second attaching element 94 provided on the collar 38 and capable of cooperating in a lockable relationship with the first attaching element 92 for locking the arms 28, 30 in the Zo closed position. In the illustrated preferred embodiment, the first attaching element 92 is a hook and the second attaching element 94 is an opening able to receive and retain the hook. It is however to be understood that any other attaching elements capable of cooperating together in a lockable relationship could also be envisaged.
As explained above, when the user depresses the U-shaped element 66, the i 5 element 66 unlocks, thereby allowing the handle 22 to extend in the extended state.
Concurrently, the depression of the U-shaped element 66 by the user then unlocks the attaching elements 92, 94.
Referring now to Figures 6, 8 and 10, preferably, the first and second members 2 0 24, 26 are each provided with a U-shaped longitudinal recess 96, 98. The U-shaped longitudinal recess 96 of the first member 24 includes an abutting wall 118 extending therein. The snow tool 20 preferably further includes a guiding spring rod 100 extending in the recesses 96, 98 of the first and second members 24, 26 and attached to a point 120 of the second member 26. The guiding spring rod 100 25 cooperates with the abutting wall 118 for keeping the compression spring 74 in position. In a preferred embodiment, the compression spring 74 can also be associated with a spring cover 104, as illustrated on Figures 9.
Referring again to Figures 5 and 6 and also to Figures 10, the second member 3 0 26 of the snow tool 20 can advantageously be provided with a scraper 106 extending at a free end 108 of the second member 26 for removing ice. Furthermore, the snow ll tool 20 can also include squeegees 110, 112 mounted respectively on the arms 28, 30, on sides opposite to the bristles 32 to provide an even more convenient tool.
Referring now to Figures 6, 10 and 11, the second member 26 can advantageously be provided with a base element 114. Each of the second member 26 and the base element 114 can be provided with a gripping surface providing a better gripping of the snow tool 20 by the user. These two parts and most of the other elements of the snow tool 20 can be made of plastic but other convenient materials such as wood could also be envisaged.
