    Description

    TECHNICAL FIELD



    [0001] The present invention relates to handheld tools, and more specifically to a pruning tool.

    BACKGROUND



    [0002] Tools, such as pruning tools, are well known in the art and generally used for performing various gardening operations, such as trimming, pruning, cutting etc. A typical pruning tool for performing cutting or pruning operation may include an outer tube, an inner tube telescopically disposed in the outer tube, and a pruning mechanism operably connected to the inner tube. In order to operate such pruning tool, a force may be applied to pull a handle coupled to the inner tube to provide sliding movement of the inner tube within the outer tube. This result in actuation of the pruning mechanism operably connected to the inner tube to perform the pruning operation. Typically, the inner tube remains in a surface contact with the outer tube, during relative movement i.e. sliding movement, of the inner tube. Such relative movement between the inner tube and the outer tube may result in friction, which may lead to wear and/or tear of the inner tube and the outer tube. Further, in order to avoid any mismatch during telescopically disposing the inner tube in the outer tube, the inner tube and the outer tube need to be designed with precision.

    [0003] The US Patent 5,960,546 (hereinafter referred as the Patent '546) discloses a pruning device. The pruning device is used for cutting limbs. The pruning device includes a hollow tubular pole having an actuating assembly mounted on a first end of the pole, and a cutting assembly for engaging and cutting a limb mounted on a second end of the pole. A cable extends axially through the pole. The cable is connected at one end to the actuating assembly, and at the other end to the cutting assembly. The actuating assembly applies pulling force to the cable upon its operation. The cable triggers operation of the cutting assembly when the cable is subjected to pulling force. The cutting head includes a hook adapted to receive the limb, and a cutting blade pivotally mounted to the hook for cutting the limb. The blade pivotally moves toward the hook upon operation of the actuating assembly. The cutting head also includes a pulley assembly through which the cable is run upon exiting the pole.

    [0004] Another example is provided by EP0895712 which discloses a lopper. The lopper is provided with a spring-biased blade cooperating with a jaw, a drive mechanism, and an elongate housing. The drive mechanism includes first and second wheels rotatable relative thereto about a first axis. A head line couples the first wheel to the blade at a connecting point, and the second wheel is coupled to a driving line. The first wheel is eccentric relative to the second wheel so that a distance separating a region of a guiding surface of the first wheel from the first axis is smallest at a predetermined point of blade travel across the bight. The lopper also includes an intermediate handle and a lower handle selectively operable to actuate the blade relative to the jaw.

    [0005] Therefore, in light of the foregoing, there is a need for an improved tool.

    SUMMARY



    [0006] In view of the above, it is an objective of the present invention to solve or at least reduce the problems discussed above. The objective is achieved by a handheld tool according to claim 1. The handheld tool includes a pole member having a first end and a second end distal to the first end. The handheld tool also includes an implement member operably disposed at the first end of the pole member. The handheld tool further includes a handle member having a holding portion and an elongated tube portion extending from the holding portion. Furthermore, the handheld tool includes a cable member extending through the pole member to connect the implement member with the handle member. The second end of the pole member includes a cover portion having an opening of a diameter corresponding to an outer diameter of the elongated tube portion. The outer diameter of the elongated tube portion is less than an inner diameter of the pole member. The elongated tube portion is provided with a sliding member slidably associated with the pole member for allowing telescopic movement of the elongated tube portion with respect to the pole member. Since the outer diameter of the elongated tube portion is less than the inner diameter of the pole member, any likelihood of wear and/or tear of the elongated tube portion and the pole member is substantially eliminated. In addition, any possibility of dimensional mismatch during telescopically disposing the elongated tube portion with respect to the pole member is substantially eliminated.

    [0007] According to an aspect of the present invention, the elongated tube portion includes a first end portion connected to the holding portion and a second end portion provided with the sliding member.

    [0008] According to another aspect of the present invention, the cable member includes a first engaging portion connected to the implement member and a second engaging portion connected to at least one of the sliding member and the holding portion.

    [0009] According to yet another aspect of the present invention, the telescopic movement of the elongated tube portion actuates the cable member to operate the implement member.

    [0010] According to yet another aspect of the present invention, an outer diameter of the sliding member corresponds to the inner diameter of the pole member allowing the telescopic movement of the elongated tube portion with respect to the pole member.

    [0011] According to an aspect of the present invention, a movement of the sliding member with respect to the pole member is restricted at a predefined distance from the opening of the cover portion. Since the movement of the sliding member is restricted at the predefined distance, the handle member remains in stable position when operated to an operating condition. More specifically, movement of the handle member is halted when the movement of the sliding member is restricted, thereby avoiding unexpected dismantling of the handle member from the handheld tool.

    [0012] According to another aspect of the present invention, the diameter of the opening is less than the outer diameter of the sliding member.

    [0013] According to another aspect of the present invention, the elongated tube portion is composed of a material selected based on a material of the cover portion to substantially reduce friction between the elongated tube portion and the cover portion. Since friction is substantially reduced between the cover portion and the elongated tube portion, any likelihood of wear and/or tear of the cover portion and the elongated tube portion is substantially eliminated. Moreover, a manufacturing cost of the handheld tool is significantly reduced in addition to maintenance of the handheld tool.

    [0014] According to yet another aspect of the present invention, the holding portion has a substantially D-shaped profile.

    [0015] According to yet another aspect of the present invention, the handheld tool further includes a handle bar extending laterally from the pole member.

    [0016] According to yet another aspect of the present invention, the handheld tool further includes an actuating mechanism disposed at the first end of the pole member and interfaced between the implement member and the cable member.

    [0017] According to yet another aspect of the present invention, the cable member is composed of a material which is axially non-elastic.

    [0018] According to yet another aspect of the present invention, the handheld tool is a pruning lopper.

    [0027] The cover portion 126 of the tool 100 may be fixedly connected to the pole member 102, thereby minimizing or eliminating any relative movement between the pole member 102 and the cover portion 126. The cover portion 126 includes a receiving end 134. According to the invention, the cover portion 126 includes an opening 140. More specifically, the receiving end 134 of the cover portion 126 includes the opening 140 having a diameter D. The diameter D of the opening 140 corresponds to an outer diameter OD2 of an elongated tube portion 144, which will be described later in the present invention. Further, the cover portion 126 includes a stopping member 141 extending axially from the receiving end 134.

    [0028] The handle member 128 of the tool 100 is disposed at the second end 108 of the pole member 102. The handle member 128 includes a holding portion 142 and the elongated tube portion 144 extending from the holding portion 142. In the illustrated embodiment, the holding portion 142 has a substantially D-shaped profile. In various other embodiments, the holding portion 142 may have a T-shaped profile or the like. The holding portion 142 may include a gripping member 146 and an engaging member 148. The gripping member 146 may be provided to assist a user to operate the tool 100. The engaging member 148 of the tool 100 may be attached to the gripping member 146. The engaging member 148 may be associated with the implement member 104, which will be described later in the present disclosure. The handle member 128 of the tool 100 may be operable between an operating condition and a non-operating condition. The operating condition herein refer to a condition of the handle member 128 in which the holding portion 142 of the handle member 128 is extended or pulled outwardly by applying a pulling force.

    [0029] FIG. 4 shows a partial sectional view of the handheld tool 100, when the handle member 128 is in the non-operating condition, according to an embodiment of the present invention. Referring to FIGS. 2, 3, and 4, the elongated tube portion 144 is connected to the holding portion 142 of the handle member 128. The elongated tube portion 144 is adapted to be disposed within the pole member 102, and telescopically movable with respect to the pole member 102 via the holding portion 142. The elongated tube portion 144 is adapted to be recived within the pole member 102 through the receiving end 134 of the cover portion 126 connected to the second end 108 of the pole member 102.

    [0030] In the illustrated embodiment, the elongated tube portion 144 may have a substantially circular shaped cross-section. In various other embodiments, the elongated tube portion 144 may have a square shaped cross-section, a polygonal shaped cross-section, a triangular shaped cross-section, a rectangular shaped cross-section or any other shape of cross-section known in the art, without limiting the scope of the present invention.

    [0031] The elongated tube portion 144 may have a second inner cylindrical surface 150 and a second outer cylindrical surface 152 distal to the second inner cylindrical surface 150. The second inner cylindrical surface 150 has an inner diameter ID2 of the elongated tube portion 144, interchangeably referred to as a second inner diameter ID2. The second inner cylindrical surface 150 may define a second recess 154. The second outer cylindrical surface 152 has an outer diameter OD2 of the elongated tube portion 144, interchangeably referred to as a second outer diameter OD2. The outer diameter i.e. the second outer diameter OD2 of the elongated tube portion 144 is less than the inner diameter i.e. the first inner diameter ID1 of the pole member 102. Further, the second outer diameter OD2 of the elongated tube portion 144 is substantially equal to the diameter D of the cover portion 126, thereby allowing movement of the elongated tube portion 144 within the pole member 102 through the opening 140 of the cover portion 126. The elongated tube portion 144 is composed of a material selected based on a material of the cover portion 126 to substantially reduce friction between the elongated tube portion 144 and the cover potion 126. For example, aluminium may be selected as the material for composing the elongated tube portion 144 if the cover portion 126 is made of an elastomeric material. Since friction is substantially reduced between the cover portion 126 and the elongated tube portion 144, any likelihood of wear and/or tear of the cover portion 126 and the elongated tube portion 144 is substantially eliminated.

    [0032] Further, the elongated tube portion 144 includes a first end portion 156 and a second end portion 158 distal to the first end portion 156. The first end portion 156 of the elongated tube portion 144 is connected to the holding portion 142 of the handle member 128. More specifically, the first end portion 156 is connected to the engaging member 148 of the holding portion 142. The second end portion 158 is provided with a sliding member 160 slidably associated with the pole member 102 for allowing the telescopic movement of the elongated tube portion 144 with respect to the pole member 102.

    [0033] The sliding member 160 moves along with the elongated tube portion 144 when the handle member 128 is operated to the operating condition. The movement of the sliding member 160 with respect to the pole member 102 is restricted at a predefined distance (not shown) from the opening 140 of the cover portion 126. In the present embodiment, the stopping member 141 of the cover portion 126 restricts the movement of the sliding member 160 at the predefined distance from the opening 140 of the cover portion 126. Since the movement of the sliding member 160 is restricted at the predefined distance, the handle member 128 remains in stable position when operated to an operating condition. More specifically, movement of the handle member 128 is halted when the movement of the sliding member 160 is restricted, thereby avoiding unexpected dismantling of the handle member 128 from the tool 100 while operating the handle member 128 to the operating condition. In the present embodiment, the elongated tube portion 144 and the sliding member 160 may be integral parts. In another embodiment, the elongated tube portion 144 and the sliding member 160 may be non-integral parts.

    [0034] As shown in FIG. 4, the sliding member 160 has a substantially polygonal shaped cross-section. In various other embodiments, the sliding member 160 may have a circular shaped cross-section, a square shaped cross-section, an elliptical shaped cross-section, a triangular shaped cross-section, a rectangular shaped cross-section or any other shape of cross-section known in the art, without limiting the scope of the present invention.

    [0035] The sliding member 160 includes an inner surface (not shown) and an outer surface 164 distal to the inner surface. The inner surface may have an inner diameter (not shown) of the sliding member 160, interchangeably referred to as a third inner diameter. The third inner diameter may be substantially equal to the second outer diameter OD2 of the elongated tube portion 144. The inner surface may define a recess (not shown) for receiving the second end portion 158 of the elongated tube portion 144.

    [0036] The outer surface 164 of the sliding member 160 has an outer diameter OD3, interchangeably referred to as a third outer diameter OD3. The third outer diameter OD3 of the sliding member 160 corresponds to the first inner diameter ID1 of the pole member 102 allowing the telescopic movement of the elongated tube portion 144 with respect to the pole member 102. More specifically, the third outer diameter OD3 of the sliding member 160 may be substantially equal to the first inner diameter ID1 of the pole member 102, thereby allowing the telescopic movement of the elongated tube portion 144 with respect to the pole member 102. Further, the diameter D of the opening 140 of the cover portion 126 is less than the third outer diameter OD3 of the sliding member 160.

    [0037] Referring to FIGS.2, 3, and 4, the tool 100 also includes a cable member 166 extending through the pole member 102 to connect the implement member 104 with the handle member 128. The cable member 166 may be composed of a material which is radially elastic and axially non-elastic. The material may include, but is not limited to, leather, plastic, artificial fibers, and natural fibers. In an embodiment, a length of the cable member 166 may be selected in order to restrict the movement of the pole member 102 at the predefined distance from the opening 140 of the cover portion 126, when the handle member 128 is operated to the operating condition. The cable member 166 includes a first engaging portion 168 and a second engaging portion 170. The first engaging portion 168 is connected to the implement member 104 of the tool 100. More specifically, the first engaging portion 168 is connected to the implement member 104 through an actuating mechanism 172 disposed at the first end 106 of the pole member 102. The actuating mechanism 172 is interfaced between the implement member 104 and the cable member 166.

    [0038] Further, in the present embodiment, the second engaging portion 170 of the cable member 166 is connected to the holding portion 142. More specifically, the second engaging portion 170 of the cable member 166 is connected to the engaging member 148 of the holding portion 142. The cable member 166 is actuated by the telescopic movement of the elongated tube portion 144 to operate the implement member 104. The cable member 166 is provided to transfer the telescopic movement of the elongated tube portion 144 to the implement member 104 through the actuating mechanism 172 for performing various operations. More specifically, the cable member 166 is adapted to operate the actuating mechanism 172 which in turn actuates the implement member 104, when the elongated tube portion 144 telescopically moves with respect to the pole member 102.

    [0039] FIG. 5 illustrates a partial sectional view of the handheld tool 100, when the handle member 128 is in the operating condition, according to an embodiment of the present invention. Referring to FIGS. 3 and 5, in order to operate the tool 100, the handle member 128 is operated to the operating condition by applying a pulling force. When the holding portion 142 is subjected to the pulling force, the elongated tube portion 144 telescopically moves with respect to the pole member 102.

    [0040] During such telescopic movement of the elongated tube portion 144, the sliding member 160 of the elongated tube portion 144 remains in contact with the first inner cylindrical surface 110 of the pole member 102. When the sliding member 160 of the elongated tube portion 144 abuts the stopping member 141 of the cover portion 126, movement of the handle member 128 is restricted while applying the pulling force on the handle member 128. More specifically, the telescopic movement of the elongated tube portion 144 is restricted while operating the handle member 128, when the sliding member 160 of the elongated tube portion 144 abuts the stopping member 141 of the cover portion 126.

    [0041] Further, when the handle member 128 is operated to the operating condition, the second engaging portion 170 of the cable member 166 moves along with the handle member 128, thereby moving the first engaging portion 168 of the cable member 166. Subsequently, movement of the first engaging portion 168 of the cable member 166 triggers the actuating mechanism 172 which actuates the implement member 104. More specifically, the actuating mechanism 172 is triggered due to the movement of the first engaging portion 168 to rotate the movable member 116 of the implement member 104 about the pivot 120 to perform cutting operation or trimming operation.

    [0042] As explained earlier, the second outer diameter OD2 of the elongated tube portion 144 is less than the first inner diameter ID1 of the pole member 102. Therefore, during the telescopic movement of the elongated tube portion 144 possibility of wear and/or tear of the elongated tube portion 144 and the pole member 102 is substantially eliminated. In addition, any possibility of dimensional mismatch during telescopically disposing the elongated tube portion 144 with respect to the pole member 102 is substantially eliminated. Moreover, a manufacturing cost of the tool 100 may be significantly reduced in addition to maintenance of different components, such as the elongated tube portion 144 and the pole member 102, of the tool 100.

    [0043] FIG. 6 shows a partial sectional view of a handheld tool 200, according to another embodiment of the present invention. Similar to the tool 100 in the FIG. 1, the handheld tool 200 in FIG. 6 includes the pole member 102, the implement member 104 operably disposed at the first end 106 of the pole member 102, and the actuating mechanism 172 for actuating the implement member 104. Further, similar to the tool 100 of the FIG. 1, the handheld tool 200 also includes the handle member 128 and the cable member 166. The handle member 128 is connected to the cable member 166. Similar to the handheld tool 100 of FIG. 1, the cable member 166 includes the first engaging portion 168 and the second engaging portion 170. The first engaging portion 168 is connected to the implement member 104. However, in the present embodiment, the second engaging portion 170 of the cable member 166 is connected to the sliding member 160 of the handle member 128. It should be noted that other constructional details and operational features of all other components of the handheld tool 200 of FIG. 6 is similar to the constructional details and operational features of the tool 100 of FIG. 1.

    [0044] In the drawings and specification, there have been disclosed preferred embodiments and examples of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for the purpose of limitation of the scope of the invention being set forth in the following claims.
