[0001] This application claims the benefit of U.S. Application Serial No. 18 / 936,862, filed November 4, 2024, which is incorporated herein by reference in its entirety. Background Technology

[0002] Windows can include screens and splines to aid ventilation and keep insects out of enclosed spaces such as homes or offices. Window screens allow air to pass through the window frame while preventing insects from entering the enclosed space. Splines may consist of a flexible strip of material used to secure the window screen to a groove in the window frame. Improved technologies for replacing screens and splines are worth having.

[0009] Various implementations will be described below. Specific configurations and details are set forth for illustrative purposes to provide a thorough understanding of the implementations. However, it will be apparent to those skilled in the art that these implementations can be practiced even without these specific details. Furthermore, some well-known features may be omitted or simplified in order not to obscure the described implementations.

[0010] Sometimes, window screens and / or screen retainers may need to be replaced. A typical replacement process may involve removing the screen retainer from its recess in the window frame. The screen retainer may be made of a flexible material, such as rubber or vinyl. It is important to remove the screen retainer carefully to avoid damaging the window frame. Once the screen retainer is removed, the window screen can be taken off.

[0011] Clean the window frame to remove any debris, then place the new window screen on the window with its edge overlapping a groove in the window frame. A screen retainer strip can be placed on top of the window screen above the groove. The screen retainer strip can then be pressed into the groove to secure the window screen to the window frame. For example, the groove can have a shape (e.g., rectangular, circular, or other shapes), and the screen retainer strip can be arranged on top of the window screen to have a rectangular shape corresponding to the shape of the groove. The screen retainer strip can be pressed downwards into the groove from a single point and continues to be pressed downwards along the groove until the entire screen retainer strip is pressed downwards into the groove to secure the window screen.

[0012] In many cases, conventional yarn pressing rollers can be used to press the yarn into the groove. Many conventional yarn pressing rollers are similar to pizza cutter rollers with movable rollers. One problem with conventional yarn pressing rollers is that the movement required to press the yarn in may require positioning the tool at an awkward angle. Furthermore, at this awkward angle, the rolling motion of the tool can be difficult to control, and the tool may easily roll out of the groove. Another problem is that, depending on the available space in the corner of the groove, conventional yarn pressing rollers may not be able to press the yarn into the corner sufficiently.

[0013] The embodiments described herein address the aforementioned problems by providing a technique for pressing a screen strip into a recess in a window frame to secure a window screen. In some embodiments, the screen and screen strip replacement tool may include a handheld tool having a handle attached to a body. The body may include a generally curved edge. The curved edge may include two edge tips at each end of the curve. The edge provides a contact area for pressing down on the screen strip, and the edge tips can be used to press the screen strip at corners. Furthermore, the tool described herein may use a rocking motion (rather than the rolling motion of a conventional screen strip roller tool) to press the screen strip into the recess.

[0014] Provided Figure 1 , Figure 2 and Figure 3 This is to show example tools for replacing window screens from different perspectives.

[0015] Figure 1This is a schematic diagram 100 of an example screen and screen pressing tool according to one or more embodiments. Tool 102 may include a handle 104 and a body 106 for pressing the screen pressing strip into a recess in a window frame. The handle 104 can be used to hold tool 102 for transporting tool 102, or for using tool 102 to replace screen pressing strips and screens. The handle 104 may be an ergonomically designed handle for replacing window screens. The handle 104 may have a generally cylindrical shape to allow the handle 104 to be gripped. In some embodiments, the handle 104 may be manufactured to have a length A 108. For example, in some embodiments, the handle 104 may have a length A 108 that is 5 1 / 16 inches (e.g., 5 1 / 16 inches), or within a threshold range of that value (e.g., within 1 / 16 inch). The handle may also have a width B 110. In some cases, the width B 110 may be 1 inch (1 inch) or within a threshold range of that value. The body 104 can be made of various materials, such as plastic, bioplastic, rubber and other suitable materials. It should be understood that although the illustrated handle 104 has a curved shape, those skilled in the art will envision various other forms that can be attached to the body 106 (e.g., straight handle, rigid angle handle or other handle forms).

[0016] The body 106 can be connected to the handle 104 and used for pressing the screen strip and changing the screen. The body 106 may have a flat or nearly flat surface. As shown, the body 106 may have a first edge 112 for pressing downward onto the screen strip and into a groove in the window frame. As shown, the first edge 112 may be curved, and its entire curvature can contact the screen strip. This curvature allows the tool 102 to be used using the swinging motion described above. Figure 4 This swinging motion is described in more detail. Typically, tool 102 contacts the pressure strip and moves clockwise and counterclockwise as it is pressed into the pressure strip. The width of the first edge 112 can be configured to allow the body 102 to be inserted into a recess in the window frame. For example, if the width of the recess is half an inch, the width of the first edge 113 can be less than half an inch.

[0017] As shown, each end of the first edge 112 may have an edge tip. As shown, one end may include a first edge tip 114, and the opposite end may include a second edge tip 116. As shown, the edge tips may be angled to form sharp corners. In some embodiments, this angle may be acute to allow each edge tip to be pressed into an angled recess in the window frame. For example, the second edge 118 and the first edge 112 may be joined to form an acute angle. In some embodiments, the second edge 118 and the first edge 112 may be joined to form a right angle. In other embodiments, the second edge 118 and the first edge 112 may be joined to form an obtuse angle. The second edge 118 may be manufactured to have a length C 122. In some embodiments, the length C 122 may be half an inch (e.g., 1 / 2 inch) or within a threshold range of that value. Although shown as an angle, in some embodiments, the edge tip may be curved. In these embodiments, the second edge 118 and the first edge 112 may generally form an acute angle, a right angle, or an obtuse angle. The body 106 may also include a third edge 120. In some embodiments, the third edge 120 may extend from the second edge 118 to the handle 104. As shown, the third edge 120 may be curved, or in other embodiments, the third edge 120 may be straight.

[0018] The first edge 112 may also have a second edge tip 116. In some embodiments, the angle formed by the first edge 112 and the fourth edge 124 may be an acute angle to allow each second edge tip 116 to be pressed into an angled recess in the window frame. In some embodiments, the fourth edge 124 and the first edge 112 may be joined to form a right angle or an obtuse angle. Although shown as an angle, in some embodiments, the second edge tip 116 may be curved. In these embodiments, the fourth edge 124 and the first edge 112 may generally form an acute angle, a right angle, or an obtuse angle. In other embodiments, one of the first edge tip 114 and the second edge tip 116 may be angled, while the other edge tip may be curved. The body 106 may also include a fifth edge 126. In some embodiments, the fifth edge 126 may extend from the fourth edge 124 to the handle 104. As shown, the fifth edge 126 may be curved, or in other embodiments, the fifth edge 126 may be straight.

[0019] The first edge tip 114 and the second edge tip 116 may be manufactured to be separated by a length D 128. In some embodiments, the length D 128 may be 5 3 / 8 inches or within a threshold range of that value. The body 106 may have a first radius E 130 extending from the center point to the first edge 112. In some embodiments, the first radius E 130 may be 3 8 1 / 256 inches (e.g., 3 8 1 / 256 inches) or within a threshold range of that value. The body 106 may also include a second radius F 132. In some embodiments, the second radius F 132 may be 2 3 / 8 inches (e.g., 2 3 / 8 inches) or within a threshold range of that value.

[0020] Figure 2 This is a schematic diagram 200 of an example screen window and a screen pressing tool according to one or more embodiments. Figure 2 With Figure 1 Tool 102 is presented from different perspectives. Figure 2 The cylindrical shape of the handle 104 is shown. It is also shown that the first edge 112, the first edge tip 114, the second edge tip 116, the second edge 118, the third edge 120, the fourth edge 124, and the fifth edge 126 may have widths extending from the first body surface 202 to the second body surface 204. In some embodiments, the widths may be uniform. In other embodiments, the first edge 112, the first edge tip 114, the second edge tip 116, the second edge 118, the third edge 120, the fourth edge 124, and the fifth edge 126 each have their own width. For example, the first edge 112 may have a length extending from the first edge tip 114 to the second edge tip 116. In some embodiments, the width of the first edge 112 may be a uniform width from the first edge tip 114 to the second edge tip 116. To illustrate examples of different widths, the respective widths of the third edge 120 and the fifth edge 126 may differ from the width of the first edge 112. As described above, tool 102 can be manufactured such that the first edge 112 has a width configured to fit within a groove in the window frame.

[0021] For example, the body 106 may have a first body surface 202 located on one side and a second body surface 204 located on the opposite side. The first body surface 202 and the second body surface 204 may be spaced apart along their edges, wherein the width of the surfaces may be based on the width of the window frame recess, as described above.

[0022] Figure 3This is a schematic cross-sectional view of an example of a screen and screen pressing tool according to one or more embodiments. As shown, the body 106 can be inserted into the handle 104. In some embodiments, the length G 302 of the body 104 can be inserted into the handle 106. In some embodiments, the length G 302 can be half an inch (e.g., 1 / 2 inch) or within a threshold range of that value. Figure 3 The body 106 is shown having a first portion having a first thickness located outside the handle 104 and a second portion having a second thickness inserted inside the handle 104. It should be understood that in some embodiments, the body 106 may have a uniform thickness. The body 104 may include a channel 304 including a recessed surface, a portion of which is recessed inward into the body 106. This recessed portion may be formed to have a desired radius. For example, in some embodiments, the recessed portion may have a radius of 7 / 128 inch (e.g., 7 / 128 inch), or within one-sixteenth of an inch of 7 / 128 inch.

[0023] The recessed portion may have a surface profile that complements the surface profile of the pressure strip 306. For example, as shown, the pressure strip 306 may have a convex surface profile, while the recessed portion of the channel 304 has a concave surface profile. This complementary surface profile allows the channel 304 to firmly hold the pressure strip in place when pressed downwards. This complementary profile also helps prevent the channel 304 from slipping off the pressure strip 306 when pressed downwards. As mentioned above, conventional pressure strip roller tools can easily roll off the pressure strip. The embodiments described herein may provide a channel 304 having a portion that has a surface profile complementary to the surface profile of the pressure strip 306. It should be understood that, as shown, the pressure strip 306 and the channel 304 have complementary circular surface profiles. Other complementary profiles will be conceived by those skilled in the art. For example, both the pressure strip 306 and the channel 304 may have triangular surface profiles, serrated surface profiles, or other suitable surface profiles. The combination of the surface profiles of the pressure strip 306 and the channel 304 helps to secure the pressure strip 306 and prevent the channel 304 from moving off the pressure strip 306. Therefore, the tool 102 can be manufactured to have a channel 304 having a surface profile that matches the surface profile of the pressure strip.

[0024] supply Figure 4 and Figure 5 This is to illustrate the use of tool 102 for replacing window screens.

[0025] Figure 4This is a schematic diagram of the swinging motion of an example screen and screen-pressing tool according to one or more embodiments. As described above, the structure of tool 102 allows for a back-and-forth swinging motion to press the screen-pressing strip into a groove in the window frame. The screen-pressing strip can be positioned above the window screen to be pushed into the groove. Tool 102 is shown in different positions at different times.

[0026] In T0402, tool 102 can be in its initial position and slightly rotated to the left of the upright position. Tool 102 can be pressed down on the screen bar to push the screen bar into the groove of the window frame. Tool 102 can be rotated clockwise. The rotation can be along the horizontal axis of tool 102. As tool 102 rotates, the first edge 112 of tool 102 can press down on the screen bar 306, pressing more screen bar into the groove, thereby securing more window screens to the window frame.

[0027] In T1404, tool 102 can be in an upright position. Tool 102 can continue to rotate clockwise. As tool 102 rotates, its first edge 112 can press down on the pressure strip 306, pressing more pressure strips into the groove, thereby securing more window screens to the window frame.

[0028] In T2406, the tool can be slightly turned to the right of the upright position. The tool 102 can rotate counterclockwise while sliding forward along the pressure strip 306, further pressing down the first edge 112 and securing the window screen into the groove of the window frame.

[0029] In T3408, tool 102 can be in an upright position and rotate counterclockwise. Tool 102 can slide further forward above the pressure strip 306, causing the pressure strip 306 to press the window screen downward into the groove of the window frame.

[0030] In T4410, tool 102 can be slightly turned to the left of the upright position, similar to the position in T0402. The tool can be rotated clockwise, causing the first edge 112 to push the screen bar 306 above the window screen downwards and into the groove of the window frame.

[0031] In T5412, tool 102 can be in an upright position and can continue the rotational movement as described above to push the pressure strip 306 downward onto the window screen and into the groove of the window frame. This movement continues until the pressure strip 306 is fully pushed downward into the groove, or until it reaches an angle within the groove. Figure 5 The motion of tool 102 when it reaches an angle is described.

[0032] Figure 5This is a schematic diagram 500 of an example screen window and a screen-pressing tool at a certain window frame angle according to one or more embodiments. As shown, the screen window 502 has been placed above the window frame 504. The screen-pressing strip 306 is placed on top of the screen window 502 and above the groove 506. The tool 102 can be used to push the screen-pressing strip 306 downward, so that the screen-pressing strip 306 and the screen window 502 are fixed in the groove 506.

[0033] In T0508, tool 102 can push the pressing strip 306 downward into the groove 506, as per [reference to...]. Figure 4 As described above, at T1510, the angle 512 of the groove 506 can be reached. As mentioned above, conventional yarn-pressing roller tools may not be able to accommodate the angle because the roller may not be able to rotate at a certain angle according to the groove size. The embodiments described herein depict a tool with an edge tip. At T1501, the tool 102 can be rotated so that its edge tip (e.g., first edge tip 114, second edge tip 116) presses downward at an angle 512 onto the yarn-pressing strip 306. The edge tip can push the yarn-pressing strip 306 downward at an angle 512, thereby securing the screen 502 into the groove 506.

[0034] In T2514, tool 12 can be rotated about its vertical axis. Rotation aligns the first edge 112 of tool 102 with the groove 506 of window frame 504. Tool 102 can be moved further to push the pressure strip 306 down onto screen 502 and into groove 506. This process can continue until both the pressure strip 306 and screen 502 are secured in groove 506.

[0035] Figure 6 This is an example process 600 for manufacturing a screen and a screen-pressing tool (e.g., tool 102) according to one or more embodiments. In 602, process 600 may include manufacturing a body (e.g., body 106) such that the body includes a curved first edge (e.g., first edge 112) having a first tip (e.g., first tip 114) at a first end, the first tip being defined by a first edge and a second edge (e.g., second edge 118) forming an acute angle. The body may also include a third edge (e.g., 120) extending away from the second edge, the first edge being defined by a first radius (e.g., radius E 130), and the third edge being defined by a second radius smaller than the first radius (e.g., second radius 132).

[0036] Process 600 may further include determining the surface profile of the pressure strip. For example, process 600 may include determining whether the pressure strip has a curved or straight surface profile. Channels may be configured to be complementary to the surface profile of the pressure strip. Thus, channels may be formed along a curved first edge to have a surface profile complementary to the surface profile of the pressure strip.

[0037] Process 600 may also include manufacturing a handle (e.g., 104) and attaching the handle to the body. The handle may be attached to the body at the end opposite the first edge. In some embodiments, the body and handle may be made of the same material. In other embodiments, the body and handle may be made of different materials. In some embodiments, the body and handle may be manufactured integrally. In other embodiments, the body and handle may be manufactured separately and then joined to form a screen and a screen-pressing tool.
