FIELD OF THE INVENTION
The present invention relates to hand tools. More specifically, the present invention relates to a dual purpose tool which is able to flip-out to form an L-handle and also form a T handle ratchet.
BACKGROUND OF THE INVENTION
T handle tools have a T-shaped body, including a long leg member and a short handle member. T handles usually have hexagonal-shaped tips for use with screws and other objects designed to accept a hexagonal tip. Once inserted, rotational pressure is applied to the hexagonal wrench in order to tighten or loosen the screw. The leg member and handle of the hexagonal wrench are designed to be in the shape of the letter “T” so that a user is able to grasp the handle with his hand(s) more comfortably.
T handle tools are manufactured and distributed in multiple English and metric sizes in order to facilitate their use with screw heads of multiple sizes. Such tools are usually sold in a set which includes tools of multiple sizes but are also distributed individually.
When using a T handle tool, a user will insert a leg end of the T handle tool onto the head of a workpiece such as a hexagonal screw, and will then exert rotational pressure using the handle on the handle end of the tool in order to tighten or loosen the screw. Due to the shape of the T handle tool it is particularly difficult to quickly turn a T handle tool because the user must constantly remove and replace his hand on the handle as it turns. Furthermore, the handle is usually not very easy to grip.
While the T handle tool is very helpful, there are instances due to space constrictions, that a T handle orientation is not usable and a modified orientation is needed for a hard to reach screw.
SUMMARY OF THE INVENTION
A dual purpose flip-out and T handle is able to be used in an L or modified L-handle orientation as well as a T handle orientation. The dual purpose flip-out and T handle includes a handle portion and a ratchet head and neck portion. The handle portion is coupled to the neck portion at a lockable hinge. The hinge allows the head and neck portion to rotate to an L or modified L-handle orientation or to a T handle orientation. When properly oriented the tool is able to be used to tighten or loosen objects such as screws or bolts.

DETAILED DESCRIPTION
A dual purpose flip-out and T handle enables a user to use the handle in an L or modified-L configuration and also a T or modified-T handle configuration providing a very versatile tool.
FIG. 1 illustrates a perspective view of a dual purpose flip-out and T handle 100. The handle 100 includes a first element 102 also referred to as a handle portion and a second element 104 which includes a stem portion 104′ and a head portion 104″, the head portion 104″ configured for receiving a drive 104′″. In some embodiments, the stem portion 104′, the head portion 104″ and the drive 104′″ are a single component, and in some embodiments, they are separate components. The first element 102 and the second element 104 are coupled to each other at a hinge 106. In some embodiments, the hinge 106 includes a locking mechanism. The locking mechanism is able to be any type of locking mechanism. In some embodiments, the first element 102 includes an aperture 108 for receiving the head portion 104″ of the second element 104. In some embodiments, the first element 102 includes a slot 110 for receiving the stem portion 104′ of the second element 104. The drive 104′″ is a ratchet mechanism. A drive 104′″ is able to be any size including but not limited to a ¼″ drive and a ⅜″ drive. In some embodiments, a connector device 120 couples to the drive 104′″ which then interfaces with a screw, bolt or other object. In some embodiments, the connector device 120 receives a tool 122 such as a screwdriver head which then interfaces with a screw or other object.
FIG. 2 illustrates a perspective view of the dual purpose flip-out and T handle 100 configured in a modified-L position. In an L position, the angle between the first element 102 and the second element 104 is 90°. In the modified L-position, the angle between the first element 102 and the second element 104 is greater than 90° and less than 180°. The handle 100 is able to reach 180° or more, but the closer the angle reaches to 180°, the more the handle 100 appears similar to a straight handle which is at 180°. By changing from a 180° straight handle to an L or modified-L position allows a user to tighten a nut, bolt or other object when a straight handle is not able to perform the task. For example, if a bolt is not easily accessible due to other objects nearby, a straight handle may not be able to reach the bolt; however, when configured appropriately, the handle 100 is able to reach the bolt. In some embodiments, the handle 100 is able to operate when configured at any angle.
FIG. 3 illustrates a perspective view of the dual purpose flip-out and T handle 100 in the process of being configured in the T position. By moving (e.g. rotating) the first element 102 towards the second element 104, the handle 100 is able to be configured in a T position. The configuring is able to be performed with one hand.
FIG. 4 illustrates a perspective view of the dual purpose flip-out and T handle 100 configured in the T position. When in the T position, the second element 104 is positioned within the first element 102. In some embodiments, the head portion 104″ of second element 104 is positioned within an aperture 108 of the first element 102, and the stem portion 104′ of the second element 104 is positioned within a slot 110 of the first element 102. FIG. 4 illustrates the purpose of the aperture 108, as it allows the user to access the back of the driver 104′″ in order to facilitate drive reversal. In some embodiments, the first element 102 and the second element 104 form a T handle in a different manner, for example, without the use of an aperture and a slot.
FIG. 5 illustrates a perspective view of the dual purpose flip-out and T handle 100 folding out from the T position. The second element 104 rotates around the hinge 106 in an outward motion to return to the straight configuration or an L/modified-L configuration.
FIG. 6 illustrates a side view of the lockable hinge 106 which is able to lock the handle 100 in a desired configuration. In some embodiments, the lockable hinge 106 is a detent or a push/slide switch to lock the hinge 106. For example, if a user wants to lock the configuration of a 120° angle as shown in FIG. 2, the user is able to use the lockable hinge 106 to do so. The user is also able to lock the handle in the T configuration. To unlock the hinge 106, the user positions the lockable hinge 106 in an unlock position, such as by pushing the switch in the opposite direction.
FIG. 7 illustrates a perspective view of a stem portion 104′ and head portion 104″ of a second element 104 without a drive in the head portion 104″. In some embodiments, the end of the stem portion 104′ includes one or more apertures for receiving the hinge 106. In some embodiments, the end of the stem portion 104′ includes ridges, grooves or another implementation to allow second element 104 to be configured at different positions such as 180°, 150°, 120° and 90°.
FIG. 8A illustrates a perspective view of a modified second element 804 without a drive. The modified second element 804 contains a stem portion 804′ and a head portion 804″. The stem portion 804′ of the modified second element 804 includes a smoother transition to the head portion 804″. Furthermore, the head portion 804″ is more rounded.
FIG. 8B illustrates a top view of a modified dual purpose flip-out and T handle 800 in an open configuration. As described above, the modified second element 804 contains a stem portion 804′ and a head portion 804″. The stem portion 804′ of the modified second element 804 includes a smoother transition to the head portion 804″. Furthermore, the head portion 804″ is more rounded. A handle portion 802 of the handle 800 includes an aperture 808 for receiving the head portion 804″ of the modified second element 804. The handle portion 802 includes a receiving area (e.g. a depression) configured for receiving the stem portion 804′. A lockable hinge allows motion similar to the motion of the handle 100.

FIG. 10 illustrates a flowchart of a method of manufacturing the dual purpose flip-out and T handle. In the step 1000, a first element is formed. In the step 1002, a second element is formed. In the step 1004, the first element and the second element are coupled with a hinge. The first element is configured to be hand-held and thus is sized accordingly. In some embodiments, the first element includes an aperture for receiving the head of the second element. In some embodiments, the first element includes a slot for receiving the stem of the second element. In some embodiments, the first element includes one or more holes for receiving the hinge. In some embodiments, the first element includes a receiving area for receiving the second element. In some embodiments, the first element is cast. In some embodiments, the first element is molded. In some embodiments, the first element includes a substructure insert which is inserted into an overmold. In some embodiments, the second element is one piece. In some embodiments, the second element is multiple pieces where the head section and stem section are separate components. In some embodiments, a drive is included within the head section. In some embodiments, a removable/replaceable drive is installed in the head. In some embodiments, the second element includes grooves, ridges or another implementation for aiding in locking into positions. In some embodiments, the order of the steps 1000 and 1002 is reversed or performed simultaneously. In some embodiments, the hinge is a lockable hinge.
The dual purpose flip-out and T handle is able to composed of any material. In some embodiments, the handle portion of the handle is a cast metal handle. In some embodiments, the handle is a durable plastic or rubber. In some embodiments, the handle is a combination of materials such as metal and rubber.
The dual purpose flip-out and T handle is able to be used with any type of device such as bolts, nuts, screws, and other devices with any type of drive type such as slotted, Phillips-head, hexagonal and others.
To utilize the dual purpose flip-out and T handle, a user initially configures the handle in a desired orientation. The user is able to configure the handle into an L, modified-L, T or modified-T configuration. Once in the desired orientation, the user is able to lock the handle into that configuration. The user uses the handle similarly to any other ratchet tool or T handle tool for tightening or loosening screws, nuts, bolts or other items.
In operation, the dual purpose flip-out and T handle, allows a user to reach items such as screws, nuts or bolts that are not able to be reached by standard tools. For example, if a screw is tucked away in a partially enclosed area, the handle is able to be modified into an L or a modified-L orientation to allow the user to reach the item with the handle and perform the desired task. Furthermore, the handle is able to be configured in a T handle orientation to provide a user with a better grip on the handle. The different configurations, L, modified-L, T and modified-T enable one handle to be able to used for many different tasks and reduces the number of tools required by a user.
