BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to construction tools, and more specifically to a connector installation tool configured to allow one-handed operation of installing wooden studs, floor joists, ceiling rafters, hip rafters, trusses, solid sawn, bci style I-beams and beams (hereinafter referred to as framing element) in a safe, fast and accurate manner.
2. Description of the Related Art
In the construction industry, setting up the framework for a building or a home involves many repetitive layout and measuring of the framing elements. Once the layout is completed, the framing elements must be installed. Currently, Simpson™ tie straps are common connectors or brackets employed to hang joists and rafters. These straps are generally metal, U-shaped brackets B of various sizes having outwardly extending flanges F with holes H for nails to mount the bracket B to a stud or framing element S. (See FIG. 1). They are manually or pneumatically installed, and depending on the complexity and scale of the project, it is a time consuming process. Moreover, due to the design of these brackets, they are susceptible to mishandling, and ultimately, inaccurate installation through human error from having to individually place the bracket by hand, especially in difficult to reach areas.
Thus, a connector installation tool solving the aforementioned problems is desired.
SUMMARY OF THE INVENTION
The connector installation tool includes a substantially Y-shaped body having a base, spaced bracket holding jaws extending from one side of the base to define a bracket holding space therebetween, an adjustable abutment spanning the jaws adapted to hold the bottom portion of a bracket thereon and to abut a framing element at a predefined location, and a handle portion to be securely gripped by a user. The connector installation tool eliminates the necessity of manipulating each bracket in the proper layout position prior to mounting the same due to the tool's capability of being preset to hold the bracket at the proper and accurate dimensions relative to the framing element on which the bracket will be mounted.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention relates to a connector installation tool 10 configured to ease installation of framing element brackets in a fast, safe, reliable and accurate manner. As shown in FIGS. 1-4, the connector installation tool 10 includes an elongate substantially flat, Y-shaped body having a base 13, a pair of spaced first and second bracket holding jaws 12, 14 projecting upwardly from the base 13, and an elongate handle 20 extending downwardly from the base 13. A vertically adjustable abutment 16 spans perpendicular to the bracket holding jaws 12, 14. The spacing of the jaws 12, 14 correspond to the width of a standard bracket B, and together with the top surface of the abutment 16, a bracket holding space 15 is formed therebetween.
Referring to FIGS. 2 and 4, the adjustable abutment 16 includes first and second abutment blocks 17, 18 selectively clamped together by a fastener 19. Each of the abutment blocks 17, 18 are T-shaped and disposed mirror image to each other. The spacing between the Ts forms opposing grooves that respectively accommodate first and second bracket holding jaws 12, 14 and permits the adjustable abutment 16 to ride along the jaws whenever adjustment is required. It is to be noted that the adjustable abutment 16 extends beyond the front and back surfaces of the body. (See FIG. 4). This serves two purposes. One is to provide a secure abutment surface for the bottom of the bracket B, and the other is to reliably and accurately abut the connector installation tool 10 against the framing element S. (See FIG. 1). This configuration also allows either front or rear sides of the tool 10 to be used. With respect to the first and second abutment blocks 17, 18, these may be modified so that one of the blocks is an elongate rectangular block while the other is a longer T-shaped block. Moreover, the adjustable abutment 16 may include more than two blocks to form the same, e.g. two elongate rectangular blocks and a central block interconnected to the rectangular blocks. The fastener 19 that clamps the abutment blocks 17, 18 may be biased for quick release selective clamping.
The following describes how the connector installation tool 10 is employed. Referring to FIG. 1, the user adjusts the abutment 16 to a preferred or predefined location along the first and second jaws 12, 14 by loosening the fastener 19, sliding the abutment 16 to the desired location, then tightening the fastener to securely clamp the first and second abutment blocks 17, 18 at the desired position. The bracket B is then placed in the bracket holding space 15, and the connector installation tool 10 is abutted against the framing element S at a predefined position along the framing element S. Nailing the same in place completes installation of the bracket B. Note in FIG. 1 that upper portions of jaws 12, 14 function as surrogate fingers to securely hold the bracket B in place for subsequent nailing operation. The above steps are repeated until the project is complete.
Thus, with the connector installation tool 10, no other manipulation or handling of the bracket B is required to install the same except for the initial insertion or placement of the bracket onto the tool. This reduces the chances to accidentally bend the upright portions of the bracket B that might potentially result in faulty or inaccurate installation, it reduces potential injury to the user's fingers since the connector installation tool 10 is holding the bracket B, and the tool presets the proper positioning of the bracket B resulting in more accurate installation of the connector.
While the above describes one version of the connector installation tool 10, the connector installation tool encompasses a variety of alternatives and features. For example, the connector installation tool 10 may be made from steel, plastic, wood or any other durable material. It may also be flexible to allow access to some hard to reach spots. Either bracket holding jaws 12, 14 or both may be provided with indicia 28 for more accurate adjustment of the abutment 16. To prevent dropping of the installation tool 10, the handle 20 may be provided with a hole for a lanyard 24 to be threaded therethrough. The handle 20 may also be wrapped by an ergonomic, no-slip cover for comfortable handling. When a project involves steel joists, the connector installation tool may be provided with a magnet 26 so that the tool may easily be attached to the steel joist.
The following describes other alternative connector installation tools according to the present invention. They all perform the same easy, fast, reliable, safe and accurate installation of connectors.
In FIGS. 5A-5B, the alternative connector installation tool 100 includes adjustment notches or grooves 102 disposed at predetermined intervals along the length of the first and second bracket holding jaws 112, 114. This configuration permits the adjustable abutment 116 to be adjusted to predefined positions.
In FIG. 6, the alternative connector installation tool 200 includes a longer adjustable abutment 216 and one of the bracket holding jaws 212, 214 being laterally adjustable. An adjustment stabilizing bar 230 extends from the bottom portion of the adjustable bracket holding jaw 214, and it is slidably mounted to the base of the connector installation tool 200 to provide overall stability to the tool. This embodiment permits installation of a variety of standard sized connectors of various widths.
In FIG. 7, the alternative connector installation tool 300 includes an angle finder 332 mounted to the base of the tool. This configuration insures accurate placement of the connector for joists disposed at an angle, e.g. trusses.
