Embodiment Construction

[0025] Generally speaking, one aspect of the present invention involves the use of a belt specifically designed to engage a drive mechanism, thereby converting a standard ratchet wrench into a high speed tool. This aspect generally requires that the strap have some engagement formations thereon that mate or engage with similar engagement formations in the wrench. However, as discussed further below, this engagement does not necessarily require close engagement of the components (ie, the teeth of the belt do not necessarily have to mate with the teeth of the drive structure). In addition to the strap, some retaining structure is required to maintain a certain level of engagement at the drive end while allowing the free end of the strap to be accessible to the user. By combining these different aspects of the present invention, an efficient and effective tool is formed that provides high speed operation that cannot be provided by other devices.

[0026] As suggested above, the ...

Abstract

A drive system cooperating with the drive mechanism of a ratchet wrench enables a user to use the wrench for its intended purpose and also spin the drive at high speed by pulling an endless belt. The belt is contained in a manner which causes structures on the belt to engage with exposed gear teeth of the ratchet wrench or an attachment. The containment structure provides for proper alignment and positioning of the belt to allow for the desired engagement with the drive teeth even after the user releases grip from the belt. The containment structure further allows an opposite end of the belt to hang loose and thus be easily accessible by a user. The drive system can be used on a socket ratchet without exposed teeth by adding gear teeth to a ratchet drive member or socket either permanently, as an added part or as an extension to the socket ratchet or socket.

Description

[0001] related application [0002] This application claims priority to US Patent Application No. 61 / 176,568, filed May 8, 2009, entitled "Accessory System for a Ratchet Wrench." Background technique [0003] The present invention generally relates to mechanisms for removing and installing nuts, bolts and other fasteners. More specifically, the embodiments described below provide tools and methods for installing or removing fasteners at high speed. [0004] A ratchet mechanism is typically used to force a small angular rotation of a fastener and then reverse the handle without rotating the fastener. By repeating this rotating action, the user can easily remove the fastener without taking off and putting on the wrench. This ratcheting function is typically achieved by appropriately engaging and disengaging a ratcheting mechanism such as a toothed gear and a pawl that interacts with the gear teeth in a desired manner. In several applications, the number of rotations that can ...
