Abstract

A ratchet wrench including a bicycle toolset combined therewith includes a main body having a first end including a ratchet drive head and a second end including an accommodating cavity. A toolset in a combination configuration is detachably connected to the main body and includes a length disposed in the accommodating cavity. The toolset comprises at least one bicycle tool.

First claim

What is claimed is:

1. A ratchet wrench including a bicycle toolset integrated therewith comprising:
a main body of the ratchet wrench with a first end including a ratchet drive head and a second end defining an accommodating cavity, wherein the accommodating cavity is distinct from the ratchet drive head and is formed within the main body extending longitudinally from the second end towards the first end; and
a toolset movable to a combination configuration detachably connected to the main body and including a length disposed in the accommodating cavity, wherein the toolset comprises at least one bicycle tool, wherein the toolset is a chain tool which includes a chain tool body and a body bolt, wherein the chain tool body has a first connecting portion, a second connecting portion, and a working area between the first and the second connecting portions, wherein the first connecting portion is detachably connected to the main body and disposed in the accommodating cavity when the toolset is in the combination configuration, wherein the second connecting portion includes first internal threads extending axially along a central axis and the body bolt includes first external threads engaged with the first internal threads, and wherein the body bolt is movable in the working area toward or away from the first connecting portion, wherein the second connecting portion and the working area are disposed outside the accommodating cavity when the toolset is in the combination configuration, and wherein when in the combination configuration, the toolset does not interfere with the normal operation of the ratchet drive head.

2. The ratchet wrench as claimed in claim 1 , wherein the body bolt includes second internal threads extending along the central axis and having a diameter smaller than the first external threads, wherein the toolset includes an extractor bolt engaged with the body bolt, wherein the extractor bolt includes second external threads engaged with the second internal threads, and wherein the extractor bolt is movable in the working area toward or away from the first connecting portion.

3. The ratchet wrench as claimed in claim 1 , wherein the toolset includes a closure detachably connected to the chain tool body and configured to enclose the working area, wherein when the closure encloses the working area, the closure has a limiting portion configured to limit a movement of the body bolt, and wherein the body bolt includes an end adjacent to the working area abutting the limiting portion when the closure encloses the working area.

4. A ratchet wrench including a bicycle toolset combined therewith comprising:
a main body having a first end including a ratchet drive head and a second end including an accommodating cavity; and
a toolset in a combination configuration detachably connected to the main body and including a length disposed in the accommodating cavity, wherein the toolset comprises at least one bicycle tool, wherein the toolset is a chain tool which includes a chain tool body and a body bolt, wherein the chain tool body has a first connecting portion, a second connecting portion, and a working area between the first and the second connecting portions, wherein the first connecting portion is detachably connected to the main body and disposed in the accommodating cavity when the toolset is in the combination configuration, wherein the second connecting portion includes first internal threads extending axially along a central axis and the body bolt includes first external threads engaged with the first internal threads, and wherein the body bolt is movable in the working area toward or away from the first connecting portion,
wherein the accommodating cavity has a first section and a second section, wherein the first section is adjacent to an open end of the accommodating cavity, wherein the second section is connected to the first section and adjacent to the ratchet drive head, wherein the first connecting portion and the first section are detachably connected with each other when the toolset is in the combination configuration, wherein the chain tool body includes a first connecting hole and a second connecting hole, wherein the first connecting hole extends in the first connecting portion, wherein the second connecting hole extends in a direction radial to the central axis and opens on an outer peripheral edge of the chain tool body, wherein the toolset includes a grip selectively connectible to the chain tool body in a first configuration and a second configuration, wherein the grip has a joining portion detachably connectible to the chain tool body, wherein the grip in the first configuration includes the joining portion detachably connected to the first connecting hole, wherein the grip in the first configuration is adapted to be disposed within the accommodating cavity when the toolset is in the combination configuration, and wherein when the toolset is in not in the combination configuration and includes the second connecting hole disposed outside the accommodating cavity, the grip is connectible to the chain tool body in the second configuration.

5. The ratchet wrench as claimed in claim 3 , wherein the accommodating cavity has a first section and a second section, wherein the first section is adjacent to an open end of the accommodating cavity, wherein the second section is connected to the first section and adjacent to the ratchet drive head, wherein the first connecting portion and the first section are detachably connected with each other when the toolset is in the combination configuration, wherein the chain tool body includes a first connecting hole and a second connecting hole, wherein the first connecting hole extends in the first connecting portion, wherein the second connecting hole extends in a direction radial to the central axis and opens on an outer peripheral edge of the chain tool body, wherein the toolset includes a grip selectively connectible to the chain tool body in a first configuration and a second configuration, wherein the grip has a joining portion detachably connectible to the chain tool body, wherein the grip in the first configuration includes the joining portion detachably connected to the first connecting hole, wherein the grip in the first configuration is adapted to be disposed within the accommodating cavity when the toolset is in the combination configuration, and wherein when the toolset is in not in the combination configuration and includes the second connecting hole disposed outside the accommodating cavity, the grip is connectible to the chain tool body in the second configuration.

6. The ratchet wrench as claimed in claim 4 , wherein the ratchet drive head includes a first driving portion to which a driving tool is adapted to couple, wherein the extractor bolt includes a second driving portion to which a driving tool is adapted to couple, wherein the toolset includes a driver bit selectively positionable in a first position and a second position, wherein the grip includes a cavity and the driver bit in the first position is inserted in the cavity, wherein the driver bit is adapted to be arranged in the first position when the grip is in the first configuration, and wherein the driver bit in the second position includes a first driving end detachably fastened to the first driving portion and a second driving end detachably fastened to the second driving portion.

7. The ratchet wrench as claimed in claim 5 , wherein the ratchet drive head includes a first driving portion to which a driving tool is adapted to couple, wherein the extractor bolt includes a second driving portion to which a driving tool is adapted to couple, wherein the toolset includes a driver bit selectively positionable in a first position and a second position, wherein the gri
