Definitions

• the present invention relates to an apparatus for supporting a tool.
• the present invention relates to an apparatus for supporting a tool from a support structure.
• Hand-held tools such as, chainsaws, hedge trimmers, or the like are well known in the art. Such tools are typically held by a user via one or more handles provided on the tool. However, on occasions, the user may need to free his hands to perform other tasks. In such instances, securing the tool in a safe way may be a problem, especially if the user is working in an elevated location, for example, up a tree.
• a supporting device is provided to reliably secure the tool to an external support structure, for example, a belt or a harness worn by the user.
• the supporting device may be attached to or removed from the tool by a complicated and time consuming method. Further, the supporting device may require separate means to attach it to the tool. An attachment portion of the supporting device may also involve multiple components, thereby increasing design complexity and cost of manufacturing of the supporting device.
• the supporting device generally includes a hook or a ring for attachment with the external support structure. The hook or the ring may interfere with the handling of the tool when the tool is in operation.
• the objective is to provide an improved apparatus for supporting a tool from a support structure.
• the objective is at least partially achieved according to a novel apparatus, for supporting a tool from a support structure, described in claim 1 .
• the apparatus includes a body, a clamping member for releasably securing the body to the tool, and a ring member pivotably connected to the body. Further, the ring member is movable between an idle position and a working position, the ring member being adapted to engage with the support structure in the working position. Moreover, the ring member is secured in the idle position.
• the ring member Since the ring member is reliably secured in the idle position, the ring member does not interfere with an operation of tool. Moreover, according to claim 2 the ring member is also secured in the working position and reliably support the tool from a support structure since a relative position between the ring member and the body does not change in the working position.
• the body includes two first indent sections.
• the two first indent sections releasably engage with the ring member to secure the ring member in the working position.
• the body includes two second indent sections.
• the two second indent sections releasably engage with the ring member to secure the ring member in the idle position.
• the body includes two angled portions adjacent to the first indent sections to move back the ring member to the working position.
• the body includes a third indent section for manual handling of the ring member to move the ring member to the working position.
• the body comprises a raised portion to prevent accidental movement of the ring member from the idle position.
• the first indent sections and the second indent sections are integral parts of the body. Thus, no additional part (E.g. a spring) may be required for securing the ring member in the working position or the idle position. This may simplify the design and manufacture of the apparatus, thereby reducing cost and improving reliability. Further, the third indent section, which is also an integral part of the body, also improves manual handling of the ring member.
• the ring member includes at least one attachment portion, the at least one attachment portion being attached to the body.
• the ring member is substantially horizontal in the idle position and substantially vertical in the working position relative to the body.
• the ring member is mounted on a top portion of the body. Further, according to claim 1 1 , the clamping member is mounted on the bottom portion of the body.
• the body further includes a tool engaging portion. Further, according to claim 13, the tool engaging portion is located at a bottom portion of the body. According to claim 14, wherein the tool engaging portion and the clamping member form a loop attachable to the tool. Moreover, according to claim 15, the loop formed by the tool engaging portion and the clamping member is substantially non-circular. The non-circular shape of the loop substantially reduces twisting and sliding of the apparatus along a part of the tool to which the apparatus is attached. Thus, the apparatus may be reliably fixed to the tool with lower clamping force. This may reduce deformation of and/or damage to various components, such as, the clamping member and the tool engaging portion, thereby increasing their working life. Lower clamping force may also prevent damage to the part of the tool.
• the clamping member includes two connecting portions and two intermediate portions, the two connecting portions being inserted into two apertures on the body. Further, according to claim 17, the body includes two first ribs to bias the intermediate portions of the clamping member apart from each other.
• the clamping member includes an end portion, the end portion of the clamping member being fixed to the body via a fastening member.
• the body further includes two second ribs to limit the movement of the connecting portions further within the apertures during tightening of the fastening member.
• the clamping member may be easily assembled with the body by simply loosening and tightening of the fastening member via a screwdriver.
• the support structure includes a belt or a harness of a user.
• the apparatus is removably attached to a handle of the tool.
• the tool is a chainsaw.
• the ring portion includes a hook portion to facilitate a quick hanging of the tool on the support structure.

• the ring member 104 is movable between an idle position (as illustrated in FIGS. 1 , 3 and 5) and a working position (as illustrated in FIG. 2, 4 and 6). In the idle position, the ring member 104 is substantially horizontal relative to the body 102. However, in the working position, the ring member 104 is substantially vertical relative to the body 102. As illustrated in FIGS. 1 - 3, the body 102 includes two first indent sections 114 which are configured to releasably engage with the arm portions 108 of the ring member 104 and secure the ring member 104 in the working position. As illustrated in FIG.
• the arm portions 108 are angled from the attachment portions 106 to the curved portion 110 such that a distance between the arm portions 108 is lower than a distance between ends of the first indent sections 114. This enables the ring member 104 to be secured by the first indent sections 114 in the working position. Moreover, the ring member 104 may elastically deform and move past the ends of the first indent sections 114. Further, as illustrated in FIG. 3, the body 102 includes two angled portions 116 adjacent to the first indent portions 114. The angled portions 116 moves back the ring member 104 to the working position in case the ring member 104 moves beyond the working position.
• the body 102 further includes two second indent sections 118 which releasably engage the arm portions 108 of the ring member 104 to secure the ring member 104 in the idle position.
• the indent sections 118 extend substantially horizontally to conform to the idle position of the ring member 104.
