FIELD OF THE INVENTION

The present invention relates to a spreading tool to aid in the installation of a hollow metal door frame.

BACKGROUND OF THE INVENTION

Often in commercial and industrial buildings metal framing is used along with steel doors and metal door frames. A typical metal door frame is constructed to set dimensions and brought to the site where it is installed. These door frames are hollow in structure and secured in place within the structure using shims, clips, and fasteners. The installation of the door frame in a straight and square position is critical to the final usage of the door and ensures proper opening, closing, and locking.

In a typical installation, a hollow steel door frame is placed within a rough opening. The frame is then leveled, squared, and secured into place. To properly level and square the frame, often a removable spreader is used to force and hold the door frame to the proper opening width. This spreader is typically a board sized to the opening and wedged between the opposed sides of the door frame. This spreader has the ability to push the door frame to the desired opening size.

Often metal door frames have imperfections and a tendency to twist or buckle during shipping and installation causing problems in the door frame. Although, the spreader functions for its intended purpose in maintaining the proper opening of the door frame, it has short comings. The traditional spreader is not adjustable, does not have the ability to secure itself to frame at multiple heights, does not remove or prevent imperfections and twisting during installation, and lacks the ability to pull the door frame to the desired installation width. Therefore, there is a need for an improved spreader to aid in installation of metal door frames.

SUMMARY OF THE INVENTION

An adjustable door frame spreading tool is disclosed. The tool aids in the installation of hollow metal door frames and is adjustable for use on frames of multiple sizes. The tool includes a first end, a second end opposite the first end, and an expanding/collapsing middle section connecting the first end and the second end. The first end and the second end are bifurcated. The bifurcation u-shaped and culminating in a pair of square ends. The square ends having a magnet for attachment to the door frame rabbet on either side of the door stop. The bifurcation sized to straddle the door stop and allow the square ends to contact the rabbet.

The collapsing/expanding middle section includes a plurality of apertures. The apertures sized to receive a pin. The apertures and pin allow for adjustment of the collapsing/expanding middle part. In the preferred embodiment of the present invention, the collapsing/expanding middle part is formed from two sections with one section telescopically and nestedly received within the other section. Accordingly, both sections will include apertures in alignment to receive the pin, wherein a width of the tool is adjusted by expanding or collapsing the sections and securing the width with the pin.

In use, a user will determine the width of the door frame to be installed. The user will then adjust the tool to the proper width. The user will then secure to the tool to the door frame by attaching the first end and the second end to the door frame opposite each other with the bifurcations straddling the door stop. The magnets present in the square ends will secure the tool to the door frame. These magnets have adequate strength to support and secure the tool to the door frame and pull the door frame to the proper width if the frame is slightly out of alignment or too wide. After attachment of the tool and proper alignment of the frame, the user will secure the door frame within the opening using the appropriate fasteners. The use of the tool will ensure proper alignment and expedite the installation process.

Referring now to FIG. 1-4, an adjustable door frame spreading tool, generally referred to as 10 is disclosed. The tool 10 aids in the installation of hollow metal door frames 20 and is adjustable for use on door frames of multiple sizes. The tool 10 includes a first end 101, a second end 102 opposite the first end 101, and an expanding/collapsing middle section 103 connecting the first end 101 and the second end 102. The first end 101 and the second end 102 are bifurcated. The bifurcation u-shaped and culminating in a pair of square ends 110, 111 and 120, 121. The square ends 110, 111, 120, 121 having a magnet 200 for attachment to the door frame rabbet on either side of the door stop. The bifurcation sized to straddle the door stop and allow the square ends 110, 111, 120, 121 to contact the rabbet.

The collapsing/expanding middle section 103 includes a plurality of apertures 130. The apertures 130 sized to receive a pin 131. The apertures 130 and pin 131 allow for adjustment of the collapsing/expanding middle part 103. In the preferred embodiment of the present invention, the collapsing/expanding middle part 103 is formed from two sections with one section telescopically and nestedly received within the other section. Accordingly, a first section will include one aperture adjacent to its end and a second section will include apertures 130 along its length and aligned with the aperture of the first section to receive the pin 131, wherein a width of the tool 10 is adjusted by expanding or collapsing the sections and securing the width with the pin 131.

In use, a user will determine the width of the door frame 20 to be installed. The user will then adjust the tool 10 to the proper width. The user will then secure to the tool 10 to the door frame by attaching the first end 101 and the second end 102 to the door frame 20 opposite each other with the bifurcations straddling the door stop. The magnets 200 present in the square ends 110, 111, 120, 121 will secure the tool 10 to the door frame 20. These magnets 200 have adequate strength to support and secure the tool 10 to the door frame 20 and to pull the door frame 20 to the proper width if the frame is slightly out of alignment or too wide. After attachment of the tool 10 and proper alignment of the frame 20, the user will secure the door frame 20 within the opening using the appropriate fasteners. The use of the tool 10 will ensure proper alignment and expedite the installation process.

In the preferred embodiment of the present invention, the tool 10 is provided in two parts and constructed from aluminum, although other similar shapes and types of materials may be used. According to this preferred embodiment, the expanding/collapsing middle section 103 is comprised of 1¼ inch angle aluminum is nestedly received within 1½ inch angular aluminum sleeve. Preferably, the distance of the u-shape of the bifurcation between the square ends 110, 111, 120, 121 of each side is 5 inches. This distance accommodates door stop widths of several sizes and allows for universal usage of the tool 10. Preferably, the depth of the square ends 110, 111, 120, 121 is 1¼ inches to accommodate door stop heights of several sizes and allows for universal usage of the tool 10. Preferably, the distance between the apertures 130 is 2 inches to allow for varying door frame 30 widths. Although, these are the preferred dimensions, it is anticipated that several other dimensions may be used to capture the spirit of the idea; therefore small changes in dimension are merely design choices and will not affect the function or use of the device.

While the invention has been described with reference to an exemplary embodiment(s), it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment(s) but that the invention will include all embodiments falling with the scope of the specification and the attached claims.
