FIELD OF THE INVENTION
The present invention relates to a nail driver and, more particularly, to a nail driver that will hold and allow for the insertion of nails into materials under difficult to access circumstances such as tight hard to access spaces.
BACKGROUND OF THE INVENTION
Carpenters often are required to place nails into materials that are located in hard to access locations. This may be a tight corner, between a counter and a wall, in a narrow spot between rafters or other difficult to access locations. Even though a hammer or nail gun may not fit into that location it is still a requirement that an appropriate fastener be inserted to secure the materials. The carpenter must either fudge and not do the job correctly, try to get a nail into that location and be satisfied with a poorly placed or penetrated nail or devise some Jerry rigged device to try and get the nail into the location in a meaningful manner.
Hammers and nail guns are the principal solutions that exist in prior art. U.S. Pat. No. 6,968,989 offers a hand pounded nail driver. U.S. Pat. No. 6,708,585 also offers a hand pounded nail driver: U.S. Pat. No. 5,605,271 uses a coil spring; U.S. Pat. No. 5,559,234 requires the use of a hammer: U.S. Pat. No. 4,600,135 does so by using air; U.S. Pat. No. 4,139,136 is a multi nail holder: U.S. Pat. No. 4,029,135 requires a hammer; U.S. Pat. No. 4,367,836 is an automatic driver; U.S. Pat. No. 3,979,040 uses magnets lacking a guide as you pull back on the driving rod; U.S. Pat. No. 5,181,644 requires a hammer to operate. And U.S. Pat. No. 6,286,742 requires air to operate. U.S. Pat. No. 4,367,836 is complicated in design and requires bearings to facilitate the ram portion and is limited to types and sizes of nails. U.S. Pat. No. 4,139,136 is equipped with magazines defeating the purpose of the present invention by making it too large to be placed and operated in tight working conditions.
The solutions described in other solutions only partially meet the needs of the carpenter who has a need to do the job properly and efficiently. Other prior art solutions require the use of air or are very bulky restricting them to use in only more open areas thus limiting their applications in the more difficult to access locations between tight spots, through small openings or other difficult to reach or work in locations. Some require the use of a hammer, which in many restricted locations is not possible to swing or to swing with enough force to insert the nail or without the hammer hitting surrounding materials creating damage that could be structural or cosmetic in nature. Still others only permit the use of a hand driver making it slow and tedious where large numbers of larger nails can be driver with the aid of a hammer. These issues can result in less than satisfactory work, less than secure structures or structures failing as time passes and loads are placed on the construction being performed. The overall problem results in work improperly performed because of the impossibility of access or because of the difficulty of access and since these locations are often in semi hidden locations quality control inspections may miss the problem resulting in safety or financial critical loss.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a nail driver that is a non separable bottom loader. The driver is equipped with a handle in which the nail driving rod passes through to the top of the handle. It may be driven with a hammer or manually with the driving handle. A second handle on the barrel allows the nail driver to be held in place and strike the nail that is loaded by gripping the handle on the driving rod and hitting the nail in place. A handle on the barrel allows the tool to be held steady while striking the striking area on top of the driving rod handle with a hammer. The tool is of a size that can be easily stored in a workers tool box.
It is therefore an object of the invention to provide one tool that will work in all locations for the carpenter.
It is another object of the invention to provide one tool that can be hand or hammer driven.
It is another object of the invention to fit into tighter locations than other similar solutions.
It is another object of the invention to hold multiple sized nails.
It is another object of the invention to remain one assembled tool to prevent loss or inconvenience.
It is another object of the invention to reduce cost of operations through reduced tools.

FIG. 4 is a side and top elevations view of an assembled nail driver 10 showing all components in its assembled position.
Referring to FIG. 1; a preferred embodiment of the driver portion of the nail driver 10. In the preferred embodiment there exists a long slender shaped hardened driving rod 14 with a permanently attached hammer head 12. The hammer head 12 end, being enlarged in diameter serving as a ram, over the driving rod 14 diameter and comprising a generally flattened end, to accompany a driving rod grip 20 (not shown) and provide a large generally flattened striking surface. The enlarged portion of the driving rod 14 in a preferred embodiment is weighted acting as a ram to help drive the nail (not shown) into its intended material. A driving rod 14 axially extends from the driving handle to transfer blows received from the hammer head 12 or the driving rod grip 20 to a nail located in the barrel 16 by means of a flattened end. The driving rod 14 is sufficient in length to reach the nail located in the barrel 16 and to permit the total penetration of said nail into a selected material for that purpose. A stop 22 right axially extended from the driving rod 14 driving rod 14 for retention within the barrel 16. The stop 22 in a preferred embodiment is small cylinder shaped embodiment with an enlarged end to prevent the barrel 16 from extending away from the driving rod 14. The stop 22 is sufficient in strength to facilitate the retention of the driving rod 14 into its barrel 16 through its movement up and down the barrel's channel 24.
Referring now to FIG. 2; depicts an axially extended barrel 16, having at one end a barrel grip shock absorber 28 sufficient in length to protect a users hand attached to the external portion of the barrel 16 and a hollow radial magnet 30 near the opposite end and in its preferred embodiment. This top view includes a hollow, elongated barrel 16 with magnet 30, which purpose is to magnetically hold a nail (not shown) internally to the barrel 16 for the driving rod 14 to strike, in a barrel 16 configuration with an inside diameter larger than the driving rod 14 so that the driving rod 14 (not shown) can slide with minimum friction. The barrel 16 can be a variety of diameters to accommodate a variety of nail head diameters (not shown). A channel 24, generally rectangular in shape and large enough in width to accommodate the stop 22 with minimal friction encompassing a majority of the length of one portion of the barrel 16 to permit the stop 22 to travel with long pounding strokes. In the preferred embodiment a barrel grip 18 is permanently bonded to the end of the barrel 16 away from the channel 24 end configured in such a manner to comfortably fit a user's hand. Its purpose is to hold the nail driver 10 (not shown) in position to insert the nail (not shown) into the proper location, and take up the shock of the contact from the nail driver 10 (not shown). At the end away from the channel 24 is permanently attached a shock absorber 26 of a flexible yet firm shock reducing material of sufficient size to protect the hand from receiving blows from the driving rod grip 20 (not shown) as the driver places the nail (not shown) in its deepest penetrating position and begins to contact the barrel grip 18. Below the channel 24 and before the barrel 16 end where the nail (not shown) is inserted, a generally donut shaped magnet 30 is sealably wrapped and affixed to the outside of the barrel 16 for the purpose of retaining an inserted nail (not shown) into the barrel 16 until it is forcibly driven by means of the driver (not shown) into its intended location. In the most preferred embodiment this magnet 30 would one such as a neodiaminironboride magnet 30 and would be secured with a strong resilient shrink wrap.
Referring now to FIG. 3; in the preferred embodiment of the current invention the assembled nail driver 10 is depicted. Starting at one end and working toward the other we see the hammer head 12 where a hammer would contact the present invention should a hammer be used to drive the nail (not shown) into its substrate. Next we see a shock absorber 26 permanently attached around the hammer head 12 and prior to the driving rod grip 20 to lesson impact if the hammer (not shown) should miss the hammer head 12 when being pounded. This is followed by the permanently attached driving rod grip 20 cylindrical shaped, ribbed and contoured in its preferred embodiment to lessen the possibility of the users hand slipping if the present invention is used without a hammer. In tight locations the sliding of the driving rod 14 against a nail head permits use in areas to tight to use a hammer (not shown) for pounding the hammer head 12. Following the driving rod 14 cylindrical in shape and hardened in its preferred embodiment the driving rod 14 makes contact with the nail head if being slid or pounded with a hammer forcing the nail into the material it is intended to enter. Lastly the stop 22 is encountered which acts as a retainer in the barrel 16 (not shown) preventing the barrel 16 from slipping off of the driver. This stop 22 consists of a cylindrical portion affixed with an extended diameter top portion larger than the channel 24 (not shown) located in the barrel 16 (not shown).
Referring now to FIG. 4; an assembled view of a preferred embodiment of the present invention there is provided a hammer head 12 with a generally flat striking surface for receiving blows from a pounding device such as a carpenters hammer (not shown). A shock absorber 26 permanently attached, generally tubular in shape, to reduce blow damage to the driving rod grip 20. A driving rod grip 20 configured to fit comfortably in a user's hand. A barrel grip shock absorber 28 generally tubular in shape, permanently attached to reduce shock and damage to the barrel grip 18 made of a flexible yet firm shock reducing material such as rubber, and of sufficient size to protect the hand from receiving blows from the driving rod grip 20 (not shown) when the nail is in its deepest most penetrating position. A barrel grip 18, permitting the user to hold in the nail driver 10 in place and guide the barrel 16 for positioning of the nail (not shown). A solid cylindrical driving rod 14 for contacting the nail (not shown) with the general purpose of causing the nail (not shown) to penetrate into a selected material (not shown). A barrel 16 for holding and guiding the driving rod 14 and the nail (not shown). A stop 22 inserted through the channel 24 of the barrel 16 into the driving rod 14 to prevent accidental disassembly of the present invention. In the preferred embodiment of this invention with the tool assembled as shown in FIG. 2 it shall be seen that the driving rod 14 and driving rod grip 20 are connected in such a manner as to facilitate the easy application of impacts to the nail (not shown) held in the barrel 16. That the barrel grip 18 and the driving rod grip 20 facilitate the ability to locate and insert nails(not shown) in to selected materials in tight hard to access locations as well as locations conventional insertion tools such as nail guns can access. Below the channel 24 and before the barrel 16 end where the nail (not shown) is inserted, a generally donut shaped magnet 30 is sealably wrapped and affixed to the outside of the barrel 16 for the purpose of retaining an inserted nail (not shown) into the barrel 16 until it is forcibly driven by means of the driver (not shown) into its intended location.
Provided is a description of the preferred embodiment of the present invention.
