Abstract
A shim for appliances such as windows and doors is described herein. The shim includes a stack of two or more cylinders threaded together such that twisting one or more of the cylinders causes the shim to extend. A collar cylinder may be placed through a jamb of the door or window, where an inner wall of the collar has threads. An inner cylinder is placed inside the collar, where the inner cylinder has male threads, and the inner cylinder is configured to extend when the inner cylinder is rotated relative to the collar. In some cases, a ball is mechanically connected to the inner cylinder at one end and is configured to extend away from the jamb when the inner cylinder is rotated relative to the collar. Some cases include a shim base with a ball socket configured to receive the ball.

DETAILED DESCRIPTION
(13) All illustrations of the drawings are for the purpose of describing selected versions of the present inventions and are not intended to limit the scope of the present inventions.
(14) Although this design could be utilized for any situation that needs to have a shimming structure of any kind between two surfaces, this description focuses on the examples of windows and doors, specifically the installation of appliances like doors 910 and windows 1004 to demonstrate the functionality of this design.
(15) This design utilizes a combination of threaded cylinders 104, 106, 108 and flanges 112, 114, 116, 118 to create geometry that can adjust infinitely, by booming in and out between its minimum and maximum geometry. This design provides the following advantages:
(16) As the threaded cylinders 104, 106, 108 can have an almost infinite range of thickness, it will offer the use of lighter-weight materials like plastics in most applications, and other materials like metals for heavier applications.
(17) The threaded, booming, cylindrical shims 102 are self-storing. As the geometry can be made to fit whatever size is desired, the minimum storage area can be used as a starting point, and multiples of that starting point can be used to determine the number of cylinders needed to reach the desired maximum length/height of the geometry. An example would be a window unit with a jamb thickness of , which could use three cylinders to store inside the jamb geometry and expand to fill a 2 cavity between the jamb and rough framing. (insulation & shims)
(18) To manufacture the threaded, booming, cylindrical shims 102, plastics/polymers may be injection molded. In other embodiments, the metals may be machined and/or laser-cut based on a combination of the material costs and labor costs. In still another embodiment, the threaded, booming, cylindrical shims 102 will be extruded through a screw machine.
(19) The threaded, booming, cylindrical shims 102 may be installed on the edges of windows and doors. Since this design has Boom functionality that can have a priority for both carrying heavier weights for an axial load, in some embodiments, the shims 102 may be made of metal. In other embodiments, perhaps when carrying a lighter (transverse) horizontal load, the shims 102 may be made of polymers. The shims 102 can be used as spacers in various applications across multiple industries.

(33)
(34)
(35) The collar 310 may be cylindrical in shape, and may have a flange 316 at the top. In some embodiments, the flange 316 may have holes in it to allow screws, nails, or staples to hold the collar 310 to the jamb 1016, 906. In some embodiments, an adhesive may be used to hold the collar 310 to the jamb 1016, 906. In some embodiments, friction may be used to hold the collar 310 to the jamb 1016, 906. In some embodiments, the flange 316 is at the top of the shim 102. In other embodiments, the flange 316 is at the bottom of the collar 310, towards the middle cylinder 312. The collar 310 may have female threads 318 in a chase 322 at the middle of the collar 310 cylinder.
(36) A middle cylinder 312 may screw into the collar 310 using the female threads 318 of the collar 310 and the male threads 320 of the middle cylinder 312. Similarly, an inner cylinder 314 may screw into the middle cylinder 312. The middle cylinder 312 is not present in some embodiments, and the inner cylinder 314 may screw into the collar 310. In other embodiments, there may be a plurality of middle cylinder 312 layers (additional cylinders) embedded within each other.
(37) The inner cylinder 314 may have a ball 306 at the bottom side. The ball 306 may snap into a ball socket 308 in a shim base 304. The shim base 304 may allow the shim 302 to be adjustable relative to the shim 302, so that if the rough frame is not plumb, then the ball 306 and ball socket 308 will rotate so that the shim base 304 makes a solid connection to the rough framing. See U.S. Pat. No. 12,371,941, Self-aligning jamb jack screw with partial sphere, issued to inventor Charles J. Spofford on Jul. 29, 2025, and U.S. Pat. No. 12,173,516, Self-aligning jamb jack screw, issued to inventor Charles J. Spofford on Dec. 24, 2024, both patents incorporated herein by reference in their entirety.
(38) The entire assembly of the shim base 304, ball 306, inner cylinder 314, middle cylinder 312, and the collar 310 may have a chase 322 running down the center of all components to allow for adjustment tools to access the lower tiers of the cylinders 310, 312, 314, and to permit a screw or nail to be inserted through the cylinders 310, 312, 314, ball 306, and shim base 304 into the frame.
(39)
(40) Looking at the top of the shim 302, the flange 316 of the collar 310 is visible, and inside of the chase 322 of the 310, the top of the middle cylinder 312 can be seen. The top of the middle cylinder 312 may have a hex head 402 for receiving an allen wrench for extending and retracting the middle cylinder 312 relative to the collar 310. Inside of the middle cylinder 312, the inner cylinder 314 is visible, with the chase 322 in the center of the inner cylinder 314.
(41)
(42) The ball socket 308 may be slightly larger than the diameter of the ball 306, with six tabs that are slightly smaller than the ball 306, so that the ball 306 can snap into the ball socket 308. The ball socket 308 may have a horizontal slot to hold the ball 306, and the bottom of the slot may be smaller than the ball 306 to prevent the ball 306 from going through the shim base 304. In some embodiments, the top center of the shim base 304 is raised to accommodate the ball socket 308.
(43) The shim base 304 could be made of metal such as sheet metal, aluminum, steel, carbon steel, alloy steel, stainless steel, iron, magnesium, copper, brass, bronze, zinc, titanium, tungsten, nickel, cobalt, tin, lead, silicon, chrome, graphite, or any combination thereof.

The shim base 304, ball 306, inner cylinder 314, middle cylinder 312, and collar 310 may be made of the same or different materials. The shim base 304 could be made with injection molding, compression molding, rotational molding, 3D printing, milling, stamping, casting, welding, soldering, brazing, forging, extrusion, or similar manufacturing processes (or a combination thereof).
(44)
(45) The bottom of the inner cylinder 314 may include a ball 306 attached to the inner cylinder 314 or formed together with the inner cylinder 314 during manufacturing. The ball 306 may be spherical in shape, with the top and bottom of the sphere truncated. The bottom of the 306 may be flat. The chase 322 may extend through the 306.
(46) The inner cylinder 314 and the ball 306 may be made of the materials listed above. The inner cylinder 314 and the ball 306 could be made with injection molding, compression molding, rotational molding, 3D printing, milling, stamping, casting, welding, soldering, brazing, forging, extrusion, or similar manufacturing processes (or a combination thereof). In some embodiments, the inner cylinder 314 is extruded as a long cylinder, cut to length, passed through a screw machine to place the threads on the outside, and milled to form the ball on one end.
(47)
(48) In some embodiments, the middle cylinder 312 has a hex head 402 for accepting an allan wrench through the 322. In some embodiments, the chase 322 through the female threads 704 allows a smaller allan wrench to pass through to the inner cylinder 314 to connect to a hex head on the inner cylinder 314. In some embodiments, the hex head of the middle cylinder 312 accepts a inch allan wrench.
(49) The middle cylinder 312 may be made of the materials listed above. The middle cylinder 312 could be made with injection molding, compression molding, rotational molding, 3D printing, milling, stamping, casting, welding, soldering, brazing, forging, extrusion, or similar manufacturing processes (or a combination thereof). In some embodiments, the middle cylinder 312 is extruded as a long cylinder, cut to length, passed through a screw machine to place the threads on the outside, and on the inside, and milled to form the hex head 402 on one end.
(50)
(51) The flange 316 may have a plurality of holes for receiving screws, nails, staples, or other attachment mechanisms used to hold the collar 310 to the jamb 906, 1016. In some embodiments, the flange 316 is away from the middle cylinder 312, inner cylinder 314, and the shim base 304. In other embodiments, the 316 is towards the middle cylinder 312, inner cylinder 314, and the shim base 304.
(52) The collar 310 may be made of the materials listed above. The collar 310 could be made with injection molding, compression molding, rotational molding, 3D printing, milling, stamping, casting, welding, soldering, brazing, forging, extrusion, or similar manufacturing processes (or a combination thereof). In some embodiments, the collar 310 is extruded as a long cylinder, cut to length, passed through a screw machine to place the threads on the inside, and milled to form the flange 316 on one end.
(53)
(54) In one embodiment, when the door 910 is manufactured, six holes are drilled into the jamb 906, and a shim 302 is inserted in each hole. The shims 302 may be adhered to the jamb 906 with an adhesive, or the shims 302 may be adhered with screws, staples, nails, or similar mechanical techniques. The shims 302 may be fully retracted when installed, leaving very little of each shim 302 exposed next to the jack stud 904. When the door 910 and jamb 906 are inserted in the rough opening defined by the jack stud 904 and the header plate 914, the installer may use an allan wrench to insert in each shim 302 to turn the middle cylinder 312 via the hex head 402. By turning the middle cylinder 312, the shim 302 will extend across the shim space 908 until the shim base 304 makes contact with the jack stud 904. The installer will then repeat this process with each of the shims 912 until the door 910 is secured. Next, the installer will adjust the shims 912 until the door is plumb. Once plumb, the installer may install a fastener into the chase 322 to permanently hold the shim 302 and the door 910 in place.
(55) In cases where the shim space 908 is large, the installer may partially extend some of the shims 302 before installation to hold the door 910 in place when initially positioning the door 910.
(56)
(57) In one embodiment, when the window 1004 is manufactured, six holes are drilled into the jamb 1016, and a shim 302 is inserted in each hole. The shims 302 may be adhered to the jamb 1016 with an adhesive, or the shims 302 may be adhered with screws, staples, nails, or similar mechanical techniques. The shims 302 may be fully retracted when installed, leaving very little of each shim 302 exposed next to the jack stud 1008. When the window 1004 and jamb 1016 are inserted in the rough opening defined by the jack studs 1008 and the header plate 1006, the installer may use an allan wrench to insert into each shim 302 to turn the middle cylinder 312 via the hex head 402. By turning the middle cylinder 312, the shim 302 will extend across the shim space 1010 until the shim base 304 makes contact with the jack stud 1008. The installer will then repeat this process with each of the shims 1014 until the window 1004 is secured. Next, the installer will adjust the shims 1014 until the window 1004 is plumb. Once plumb, the installer may install a fastener into the chase 322 to permanently hold the shim 302 and the window 1004 in place.
(58) In some embodiments, two shims 302 may be installed between the window 1004 and the sill 1012, at the bottom of the window 1004. In some embodiments, these two shims 1104 are under the upright jamb 1016 at the corners of the window 1004.
(59) In cases where the shim space 1010 is large, the installer may partially extend some of the shims 302 before installation to hold the door in place when initially positioning the window 1004.
