Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


This invention relates to a handle, more particularly to a handle capable of storing a tool bit.


2. Description of the Related Art


Referring to FIG. 1, a conventional hand tool includes a handle 1 that is formed with at least one hexagonal bit receiving hole 101 adapted for insertion of a tool bit 2 therein.


The hand tool is capable of storing the tool bit 2 by virtue of the bit receiving hole 101 in the handle 1. However, the tool bit 2 is required to be fully and securely contained in the bit receiving hole 101 of the handle 1 in order to avoid any discomfort caused by extension of a tip of the tool bit 2 out of the bit receiving hole 101 when holding the handle 1. Accordingly, removal of the tool bit 2 from the bit receiving hole 101 is difficult when the tool bit 2 is more securely contained in the bit receiving hole 101. On the contrary, while removal of the tool bit 2 from the bit receiving hole 101 is easier when the tool bit 2 is less securely contained in the bit receiving hole 101, the tip of the tool bit 2 is likely to extend undesirably out of the bit receiving hole 101.


SUMMARY OF THE INVENTION

The object of the present invention is to provide a handle that is capable of storing a tool bit and that can overcome the aforesaid drawbacks of the prior art.


According to this invention, a handle that is adapted for storing a tool bit therein includes a handle body and a bit retainer. The handle body has an outer surface that surrounds a longitudinal axis extending in a first direction and that has opposite surface parts opposite to each other in a second direction transverse to the first direction. The handle body further has a slot formed through the opposite surface parts of the outer surface of the handle body. The bit retainer is disposed in the slot of the handle body, and includes a bit receiving portion formed with at least one bit receiving hole that is adapted for insertion of the tool bit therein, and a pivot portion connected to the bit receiving portion and pivotally retained in the slot. The pivot portion is pivotable relative to the handle body about a pivot axis that extends in a third direction transverse to the first and second directions such that the bit receiving portion is movable relative to the handle body between a bit concealing position, where the bit receiving hole is concealed in the slot of the handle body, and a bit accessing position, where the bit receiving hole is accessible from the slot in the handle body.

The handle body 10 further includes a shank coupler 31 connected to one end of the intermediate frame part 30 and adapted for connecting to a tool shank 200. The tool shank 200 has an end that is distal from the shank coupler 31, and that has a hole adapted for insertion of the tool bit 300 therein.


Referring to FIGS. 2, 3, and 4, the bit retainer 20 is disposed in the slot 12 of the handle body 10, and includes a first bit receiving portion 200 formed with at least one bit receiving hole 22 that is adapted for insertion of the tool bit 300 therein, and a pivot portion 21 connected to the first bit receiving portion 200 and pivotally retained in the slot 12. The pivot portion 21 of the bit retainer 20 includes a pivot shaft having opposite ends along a pivot axis (L) that extends in a third direction transverse to the first direction (X) and the second direction (Y). The opposite ends of the pivot shaft of the pivot portion 21 are pivotally retained in the pivot hole 13 that is cooperatively confined by the notches 43,53 of the pivot plates 411,511.


In an alternative embodiment, the pivot plates 411,511 may be configured to pivotally retain only one of the opposite ends of the pivot shaft of the pivot portion 21.


The pivot portion 21 is pivotable relative to the handle body 10 about the pivot axis (L) such that the first bit receiving portion 200 is movable relative to the handle body 10 between a bit concealing position (see FIG. 5), where the bit receiving hole 22 is concealed in the slot 12 of the handle body 10, and a bit accessing position (see FIG. 6), where the bit receiving hole 22 is accessible from the slot 12 in the handle body 10.


In this embodiment, the bit retainer 20 further includes a second bit receiving portion 201 that is formed with at least one bit receiving hole 22, that is connected to the pivot portion 21, and that is disposed opposite to the first bit receiving portion 200 relative to the pivot axis (L). The first and second bit receiving portions 200,201 are movable relative to the handle body 10 between the bit concealing position (see FIG. 5), where the bit receiving holes 22 in the first and second bit receiving portions 200,201 are concealed in the slot 12 of the handle body 10, and the bit accessing position (see FIG. 6), where the bit receiving holes 22 in the first and second bit receiving portions 200,201 are accessible from opposite ends of the slot 12 in the handle body 10.


The bit retainer 20 further includes a pair of shielding plates 23 that are connected to and that are disposed on opposite sides of the first and second bit receiving portions 200,201 relative to the pivot axis (L). The shielding plates 23 cover the opposite ends of the slot 12 in the handle body 10 when the first and second bit receiving portions 200,201 are at the bit concealing position (see FIG. 5), and extend out of the slot 12 when the first and second bit receiving portions 200,201 are at the bit accessing position (see FIG.6).


It is noted herein that the second bit receiving portion 201 of the bit retainer 20 may be omitted in other embodiments of this invention.


The handle 100 further includes a limiting unit provided on the handle body 10 and the bit retainer 20 for limiting range of pivoting movement of the bit retainer 20 relative to the handle body 10. In this embodiment, the limiting unit includes an arcuate slide way 44,54 that is formed in the pivot plates 411,511 and that extends along a periphery of the pivot hole 13, and a stop 24 that is formed on the pivot shaft of the pivot portion 21 and that extends into the slide way 44,54.


The slide way 44,54 has an arc length not greater than 180 degrees. In this embodiment, the slide way 44,54 has an arc length equal to 180 degrees.


In this embodiment, the slide way 44,54 is cooperatively formed by the pivot plates 411,511. In other embodiments, the slide way 44,54 may be formed in only one of the pivot plates 411,511. In yet another embodiment, the stop may be formed on one of the pivot plates 411,511 and the slide way 44,54 may be formed in the pivot shaft of the pivot portion 21.


The handle 100 further includes a positioning unit that includes a first positioning member 45,55 provided on the handle body 10, and a second positioning member 25 that is provided on the bit retainer 20 and that engages removably the first positioning member 45,55 for positioning removably the first bit receiving portion 200 at the bit concealing position. In this embodiment, the first positioning member 45,55 is an indentation cooperatively formed by the pivot plates 411,511, and the second positioning member 25 is a protrusion. In other embodiments, the first positioning member 45,55 may be a protrusion formed on one of the pivot plates 411,511, and the second positioning member 25 may be an indentation formed on the bit retainer 20.


Referring to FIG. 5, when the bit retainer 20 is disposed at the bit concealing position, the second positioning member 25 engages the first positioning member 45,55. Therefore, the bit retainer 20 is not easily removed from the bit concealing position when holding the handle 100. The tool bits 300 in the bit receiving holes 22 can be fully and securely stored in the slot 12 of the handle body 10. More particularly, the presence of the tool bits 300 in the slot 12 does not result in user discomfort since the tool bits 300 are unable to protrude from the slot 12 of the handle body 10 when the bit retainer 20 is at the bit concealing position.


Referring to FIGS. 6 and 7, the bit receiving holes 22 in the first and the second bit receiving portions 200,201 are accessible from the opposite ends of the slot 12 in the handle body 10 when the bit retainer 20 is positioned at the bit accessing position according to this embodiment. Therefore, the tool bits 300 can be easily removed from or inserted into the bit receiving holes 22.


While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation and equivalent arrangements.
