The present application is in the field of construction, and more particularly to devices for adjusting and aligning a jamb assembly within a structural opening and/or with another jamb assembly.
The inventions described herein are an improvement to any of the existing ways to mount windows and doors that have been disclosed and/or offered to date.
Although there are many different designs of Jamb Jack Screws, this set of inventions is presented to resolve many of the limitations of the prior attempts and current offerings. The self-aligning functionality afforded by the ball and platform base addresses many of the challenges of aligning a window or door unit into an opening in a wall regardless of the rough framing's condition as it pertains to being Level, Plumb, Square and/or True.
In addition, the design provides an opportunity to adjust the jamb jack screw at a future date from completely inside the room without the need to remove interior casings. This is beneficial when the rough framing members swell or contract as a result of a change in moisture content.
The present inventions eliminate the issues articulated above as well as other issues with the currently known products.
A self-aligning jamb jack apparatus is described here. The jamb jack apparatus includes a cylindrical threaded adjustment component with adjustment component threads on the exterior wall and a smooth surface on the interior walls, the cylindrical threaded adjustment component extending through a cylinder with a smooth exterior to a ball, the smooth surface extending through the cylinder and the ball. The apparatus also includes a platform base with a socket configured to encompass the ball such that the platform base pivots around the ball.
In some embodiments, the apparatus also includes a cylindrical threaded base component with guide threads on the interior walls, the guide threads aligned to accept the adjustment component threads. A flange could be mechanically attached to the cylindrical threaded base component at one end of the cylindrical threaded base component, the flange extending outward, the flange including a flat surface perpendicular to the cylindrical threaded base component. The flange could have a hole in the flat surface.
In some cases, the cylindrical threaded base component has exterior threads. The cylindrical threaded adjustment component, the cylinder, and the ball could be a single piece of steel. The platform base, the cylindrical threaded adjustment component, the cylinder, and the ball are 3-D printed steel. The platform base could be brass.
The jamb jack apparatus could also include a door jamb, the cylindrical threaded base component mechanically connected to the door jamb.
The jamb jack apparatus could also include a window jamb, the cylindrical threaded adjustment component mechanically connected to the window jamb.
The jamb jack apparatus could also include an appliance jamb, the cylindrical threaded base component mechanically connected to the appliance jamb.
Alternatively, the jamb jack apparatus includes at least three parts: (1) a cylindrical threaded base component with guide threads on the interior walls, the guide threads aligned to accept adjustment component threads, an adjustment component assembly; (2) the adjustment component assembly comprising a cylindrical threaded adjustment component with the adjustment component threads on the exterior wall and a smooth surface on the interior walls, a cylinder mechanically connected to the cylindrical threaded adjustment component on one end of the cylindrical threaded adjustment component, and a ball, mechanically connected to the cylinder, the smooth surface extending through the ball; and (3) a platform base with a socket configured to encompass the ball such that the platform base pivots around the ball.
In some embodiments, the platform base is a rectangular box shape. A flange could be mechanically attached to the cylindrical threaded base component at one end of the cylindrical threaded base component, the flange extending outward, the flange including a flat surface perpendicular to the cylindrical threaded base component and the flange could have a hole in the flat surface. The cylindrical threaded base component could have exterior threads. The cylindrical threaded adjustment component, the cylinder, and the ball could be a single piece of brass. The platform base, the cylindrical threaded adjustment component, the cylinder, and the ball could be 3-D printed steel. In some embodiments, the platform base is iron. The jamb jack apparatus could also include a door jamb, the cylindrical threaded base component mechanically connected to the door jamb. The jamb jack apparatus could also include a window jamb, the cylindrical threaded base component mechanically connected to the window jamb.
The Jamb Jack Device
The base component 108 is placed in a window or door jamb 101, as seen in
The adjustment component 106 and ball 105 assembly screws into the base component 108. The adjustment component 106 and ball 105 assembly is hollow 107 as seen in
In some embodiments, the hollow 107 is threaded. The threads in the hollow 107 could be through the entire adjustment component 106 and ball 105 assembly in some embodiments, or could be partially threaded.
In some embodiments, the top of the adjustment component 106 is countersunk so that the fastener 103 is flush with the top of the adjustment component 106 as it passes through the hollow 107.
In some embodiments, the adjustment component 106 is screwed directly into the window or door jamb 101, without the base component 108.
The fastener 103 could be a machine screw, a bolt, or any other type of screw type device. The fastener could be made of steel, iron, brass, bronze, plastic, or similar material. The top of the fastener could be a Phillips head, straight head, hex head, socket head, etc. The threading for the fastener 103 could be the entire length of the shaft in one embodiment, or the fastener 103 could be only partially threaded with the threading at the end to fasten to the rough framing 102.
As seen in
In some embodiments, the adjustment component 106 could include grooves 201a,201b,201c,201d to accept a Philips head screwdriver so that the adjustment component 106 can be screwed into the door jamb 101.
The platform base 104 is seen in
The platform base 104 could be a rectangular box shape in some embodiments. In other embodiments, the platform base 104 could be round with a flat or concave or convex surface contacting the rough framing 102.
The Method of Installing the Jamb Jack Device
For one embodiment, in order to install the jamb jack device 100, a hole is placed in the window or door jamb 101. The base component 108 is inserted in the hole, and two screws are driven into the window or door jamb 101 through the screw holes 403a, 403b in the flanges 402a, 402b.
Next, the adjustment component 106 is screwed into the base component 108, providing the space difference required between the window or door jamb 101 and the rough framing 102. The platform base 104 is placed against the rough framing 102, and the adjustment component 106 is adjusted so that the platform base 104 rests firmly against the rough framing 102.
The fastener 103 is driven into the hollow 107 of the adjustment component 106 and the ball 105. The fastener 103 may continue through the ball 105 and into the rough framing 102.
While the present disclosure has been presented above with respect to the described and illustrated embodiments of the jamb jack device 100, it is to be understood that the disclosure is not to be limited to those alternatives and described embodiments. Accordingly, reference should be made primarily to the following claims rather than the foregoing description to determine the scope of the disclosure.
The foregoing devices and operations, including their implementation, will be familiar to, and understood by, those having ordinary skill in the art.
The above description of the embodiments, alternative embodiments, and specific examples, are given by way of illustration and should not be viewed as limiting. Further, many changes and modifications within the scope of the present embodiments may be made without departing from the spirit thereof, and the present inventions include such changes and modifications.
This application is a non-provisional application for which claims priority under 35 U.S.C. § 119, to U.S. Provisional Patent Application No. 63/372,079, filed Feb. 14, 2022, entitled “Self-Aligning Jamb Jack Screw,” the entire content of the above non-provisional patent application and provisional patent application is incorporated herein by reference in their entirety.
