Definitions
- the present invention relates to improvements in the means for shipping sliding and tiltable sash windows, and more particularly to apparatus which relieve the stresses imposed on the window's sash locks during transportation.
- window types available on the market, such as picture windows, bay windows, skylight windows, louvered windows, transom windows, casement windows, and the many versions of the sash window, with those being single-hung, double-hung, vertical sliding, and horizontal sliding sash windows. While the casement window is predominantly used in the United Kingdom and much of Europe, the sliding sash window remains an American favorite for both new construction and for replacement windows.
- Window manufacturers attempt to address this problem in one of a number of different ways.
- One way is to insert blocking, made from cardboard, Styrofoam or any number of various packaging-materials, materials, to support the sash windows, while other manufacturers will ship the windows in the closed position but with the sashes unlocked, and with some outer packaging solely relied upon to hold the sashes in place. But this is cumbersome and costly, not only in terms of the purchasing and needed supply of bulky packing materials, but also for its disposal.
- Another method is to open the sash window, and to turn and pack the window upside-down.
- this method creates the potential risk of damage to the window sashes and frame from sliding motion, and furthermore makes the window awkward to maneuver and handle.
- Another solution is to ship the windows closed and locked, and to use air ride type cargo vans and trailers to reduce the stress to the hardware, with a corresponding increase in shipping costs.
- This invention provides an economical and simple solution for the transportation of sash windows and doors through the use of a serrated strap.
- serrated straps There has been some limited use of serrated straps in the art.
- U.S. Pat. No. 5,852,852 to Rigal it was used in combination with a ratchet locking member as a tightening device, with particular applicability for snowboard bindings, roller skates and the like.
- the Rigal patent improved upon the prior art use of serrated straps, such as those found, for example, in U.S. Pat. No. 5,480,176 to Sims for an externally mounted binding, as well as the Ratchet-type Buckle shown by U.S. Pat. No. 5,416,952 to Dodge.
- all of these types of devices require the use of a separate pivoting ratchet element in combination with the serrated strap.
- U.S. Pat. No. 5,462,542 to Alesi discloses a more simple arrangement in the form of a “Sternum Buckle With Serrated Strap.”
- the Alesi sternum buckle assembly is adapted to be looped about the split portions of tissue.
- the serrated strap extends outward from the pawl in a single piece that is formed of a bio-absorbable material.
- the strap has a needle end to penetrate tissue, where retention of the serrations are more simply accomplished by a latch collar, and was intended to be used as a fast means of applying a suture.
- none of these approaches are capable of providing support needed for the safe transportation of a sliding sash window or door.
- Using this invention allows a sash window or door to be shipped with the sashes in the closed position, while remaining unlocked, thus eliminating stress that causes damage to the lock, keeper, and screws.
- the clip assembly of the present invention may be used to secure one or more objects, particularly the sliding sashes of a window or door during transportation, to prevent damage to the sashes or to prevent damage to the lock and keepers when shipped in the locked condition, as well as to obviate the need of using cumbersome cardboard blocking as a restraint.
- the clip assembly may be comprised of two separate molded parts—a strap member and a pawl member.
- the strap member may be formed to have a bumper portion, and a strap portion extending from the bumper.
- the bumper may preferably have an engagement wall, and a bottom wall that is supported to be approximately orthogonal to the engagement wall by first and second side walls.
- the strap portion may have a plurality of teeth formed within the thickness of the strap.
- the strap teeth may be formed to have an engagement face and a back face, which converge to create a peak, and whereby successive teeth are separated by a trough.
- the strap portion may terminate in a thinner strap section, with a ramp between the two strap sections, and where the thinner strap section may have a rounded end which may also be ramped to facilitate its insertion into the pawl.
- the pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall.
- the top wall may have a protrusion which includes a plurality of teeth formed to complement the teeth of the strap, and be located proximate to the intermediate wall.
- the teeth may be located at a distance from the intermediate wall to permit the strap to be trapped there between, once it is inserted. Insertion of the strap may be accomplished whereby the strap causes deflection of the pawl teeth and the protrusion. This required deflection of the pawl teeth and protrusion may be aided by a recess in the intermediate wall to take advantage of the flexible nature of the strap.
- a strap of the current invention may be inserted through the gap between the top rail of an upper sash and the bottom rail of the second sash, and then be inserted into the pawl, such that engagement edges of the first and second side walls of the pawl abuts the top rail of the bottom sash. Insertion of the strap into the pawl may occur by inserting the free end of the strap portion into the gap between the strap teeth and the intermediate wall, to engage the pawl teeth until the engagement edge of the first and second side walls of said pawl member firmly contacts the bottom rail of said second sash.

- FIG. 2 shows a first embodiment of the present invention, a transportation clip assembly 10 , which includes a pawl member 20 and a strap member 60 .
- FIG. 1 illustrates the strap member 60 as it is being inserted into the pawl member 20 to have engagement with, and mono-directional travel relative to, the pawl member.
- FIG. 3 shows a side view of the clip assembly 10 .
- the pawl member 20 and strap member 60 may be made from any suitable materials, including, but not limited to, plastic.
- the pawl member 20 may be formed of various different shapes, but in a preferred embodiment, as shown in FIGS. 4-7 , the pawl member 20 may have a first side wall 21 and a second side wall 22 , which may be maintained at a set distance by top wall 24 and intermediate wall 25 .
- First side wall 21 and second side wall 22 may be generally parallel to each other, but need not be so oriented.
- each of the walls may be adjusted to increase the overall strength of the clip assembly 10 .
- the strength should accommodate most, if not all, sash windows, but could be increased with the aforementioned thickness changes to accommodate larger sliding doors.
- a single sized clip may be utilized for securing various fenestration products, and when it is necessary to secure larger, heavier sliding doors, multiple transportation clip assemblies 10 may be utilized rather than a single stronger clip.
- first side wall 21 and a second side wall 22 may have an outside corner radius 53 around the periphery of the walls to eliminate any sharp edges which might tend to scrape or otherwise damage the finish of the windows.
- first and second side walls 21 and 22 may be formed with various different contours. As shown in one embodiment, side walls 21 and 22 may be formed with an engagement edge 38 that may transition into a rounded engagement corner 39 on one end, and into a lateral support edge 40 on the other end. These engagement features of the side walls 21 and 22 of pawl member 20 may bear up against the sashes of the window when engaged by the strap member 60 , as seen in FIG. 14 .
- first and second side walls 21 and 22 may comprise-various different configurations, and in one embodiment may have edges 41 and 42 , whereby edges 40 and 41 may have a straight edge transition 43 between them, or a rounded corner (not shown), and edges 41 and 42 may have a straight edge transition 44 between them.
- Edge 42 may connect tangentially to the rounded engagement corner 39 (not shown), or alternatively, there may be edges 45 and 46 , between which may be a radius 47 , and there may also be an edge 48 that may be approximately parallel to edge 45 .
- Edge 46 may transition into edge 48 using an outside corner 49 .
- Edge 48 may transition into rounded engagement corner 39 by way of edges 50 and 51 .
- edges 42 , 45 , and 46 may serve as support for a tool that may be used to apply tension to the strap member 50 relative to the pawl member 20 , and tightly secure both sashes 11 and 13 of the window relative to each other, and relative to the master frame 15 ( FIG. 15A ), as will be discussed hereinafter.
- rounded engagement corner 39 , and edges 50 and 51 may be seated between window sashes to secure the sashes.
- the section view, in FIG. 8 , through pawl member 20 reveals the top wall 24 and intermediate wall 25 as formed in a preferred embodiment.
- Intermediate wall 25 may be formed to have an axial portion, which as pictured in FIG. 8 appears as a horizontal wall portion 26 having a top surface 27 and a bottom surface 28 .
- the horizontal wall portion 26 may transition, by way of a curved region 31 , into a vertical portion 32 .
- the curved portion 31 may assist in guiding the strap member 60 to engage with the pawl member 20 .
- the vertical portion 32 may serve to support the side walls 21 and 22 , to deflect the strap member 60 when trying to engage it with the pawl member 20 , or as structural support in an alternate embodiment ( FIGS. 17-19 ).
- the top wall 24 may span the entirety of edges 40 , 41 , and 43 of the first and second side walls 21 and 22 , or may, as shown in FIG. 8 , only span a portion thereof.
- Protruding away from the top wall 24 and towards the top surface 27 of the horizontal portion 26 of intermediate wall 25 may be a triangular-shaped protrusion 23 , which forms a gap 50 with top wall 24 , making the protrusion 23 generally flexible with respect to top wall 24 .
- Triangular-shaped protrusion 23 may have a plurality of teeth 33 . Although only three teeth are shown in FIG. 8 for pawl member 20 , the number of teeth may be increased to provide greater strength in the connection between the strap member 60 and pawl member 20 , which may be required for corresponding increases in wall thicknesses, as previously described.
- each tooth may be formed to have a back face 35 , which meets a front face or engagement surface 36 at the apex 37 .
- the back face of one tooth meets the front face of an adjacent tooth may be a tough 34 .
- the back face 35 and front face 36 are shown in to be flat in FIG. 9 , with the front face being approximately perpendicular to the intermediate wall 25 ; however, other possible shapes and orientations may be utilized.
- the configuration shown may be preferable to assist in the mating of the strap member 20 with the pawl member 60 .
- the distance between the apex 37 of the plurality of teeth 33 and the top surface 27 of the horizontal portion 26 of intermediate wall 25 may be crucial to the interconnection between the strap member 60 and pawl member 20 , which is discussed further hereinafter.
- the strap member 60 may be formed to have a bumper portion 80 connected to a strap portion 61 .
- Bumper portion 80 may be formed a number of different ways.
- bumper portion 80 may be comprised of only an engagement wall 81 .
- engagement wall 81 may preferably be connected to a bottom wall 84 .
- Bottom wall 84 may preferably be approximately orthogonal to engagement wall 81 . This orthogonal relationship between bottom wall 84 and engagement wall 81 may be supported by first and second side walls 82 and 83 , which may be parallel to each other.
- All of the exterior edges of the bottom wall 84 , engagement wall 81 , and first and second side walls 82 and 83 may be rounded through use of outside corner radius 85 . Having the corners thus relieved may serve to prevent scrapes and other facial damages to the windows upon which the transportation clip assembly 10 may be installed.
- the engagement wall 81 may have a cushioning material (not shown) attached thereto to further protect the window.
- the cushioning material may include, but is not limited to, rubber that is attached to the engagement wall 81 through any acceptable means for the particular cushioning material chosen, including, but not limited to, glue or epoxy. The same cushioning material may also be utilized upon the engagement edges 38 of the first and second side walls 21 and 22 of the pawl member 20 .
- the strap portion 61 of strap member 60 may be comprised of a plain strap 62 , which may be connected to the engagement wall 81 of the bumper portion 80 using fillet radii 63 , which may thereby improve the durability of the connection.
- Plain strap 62 may, but need not, have a rectangular cross-section, having a thickness 71 .
- the plain strap 62 may transition into a serrated strap 64 , which may have the same cross-section as plain strap 62 , but which further comprises a plurality of strap teeth 66 , which may be similarly constructed as the plurality of pawl teeth 33 , but formed so as to be complementary in nature to the pawl teeth 33 so as to mesh with and thereby be retained by the pawl teeth 33 of pawl member 20 when the strap member 60 is therein inserted.
- a serrated strap 64 which may have the same cross-section as plain strap 62 , but which further comprises a plurality of strap teeth 66 , which may be similarly constructed as the plurality of pawl teeth 33 , but formed so as to be complementary in nature to the pawl teeth 33 so as to mesh with and thereby be retained by the pawl teeth 33 of pawl member 20 when the strap member 60 is therein inserted.
- the plurality of strap teeth 66 may be formed within the thickness 71 of the cross-section of the serrated strap 64 , leaving a narrow portion of plain strap 64 on each side of the strap teeth 66 , which may not extend to the full width of the serrated strap 64 .
- Proper functional engagement of the plurality of strap teeth 66 with the plurality of pawl teeth 33 is obtained through careful control of several features and dimensions. As previously stated, the distance between the apexes 37 of the plurality of teeth 33 of pawl 20 from the top surface 27 of the horizontal portion 26 of intermediate wall 25 may be crucial to this functional engagement. Proper engagement may generally depend upon trapping the serrated strap 64 against the top surface 27 of the horizontal portion 26 of intermediate wall 25 . Snugly trapping the serrated strap 64 may preferably require a combination of deflection of the protrusion 23 and deflection of the serrated strap 64 when feeding the strap member 60 into pawl member 20 .
- Deflection of the protrusion 23 may occur when the strap teeth 66 contact the pawl teeth 33 resulting in an applied load to the protrusion and causing angular deflection at the gap 50 ( FIG. 9 ) towards the top wall 24 .
- This invention furthermore takes advantage of the flexural nature of the strap portion 61 when being inserted into the pawl member 20 , through its tendency to bend or even buckle under compression loading, by incorporating a recess 29 in the top surface 27 of the horizontal portion 26 of the intermediate wall 25 .
- the recess 29 may necessitate the use of a step 52 in the lower surface 28 of the horizontal portion 26 of intermediate wall 25 to increase thickness, in order to accommodate the thickness reduction due to the recess 29 .
- the recess 29 allows the serrated strap 64 region of strap 60 to deflect downward, under the compression loading, away from the plurality of teeth 33 of the triangular protrusion 23 , as the triangular protrusion 23 and teeth 33 simultaneously deflect upward.
- the recess 29 may have curved transitions 51 with the top surface 27 of the intermediate wall 25 to facilitate bending of the strap 60 in proximity to the plurality of teeth 33 of the pawl 20 .
- the recess 29 may preferably have a maximum depth such the distance between the apex of the teeth 33 of the pawl 20 and the recess 29 is approximately equal to said thickness 71 of the strap.
- Initial engagement of the strap 60 with the pawl 20 may be furthered by having a plain strap section 67 which may be thinner than plain strap 62 , and may transition to the serrated strap 64 using a ramp 68 .
- the thin plain strap 67 may terminate in a tapered and ramped end 69 .
- the tapered/ramped end 69 may have an orifice 70 which may be used in conjunction with a tool (not shown) to apply tension to the strap 60 relative to the pawl 20 , to pre-load the window sashes 11 and 13 relative to each other, and in a direction opposite to each other, when in the closed position.
- the upper sash 11 will be loaded towards the upper portion of the master frame 15 , with a corresponding loading of the lower sash 13 towards the lower portion of the master frame.
- the tool may have a prong that retains the orifice 70 and allows the strap portion 61 to be rolled up on the tool, and whereby the roll may act against the edges 45 and 46 of first and second side walls 21 and 22 of pawl 20 .
- the ability to apply such tension between the pawl member 20 and the strap member 60 permits further engagement of one or more of the pawl teeth 33 with said strap teeth 66 to generate the pre-loaded sash arrangement.
- the pre-loaded window sashes 11 and 13 will be biased away from each other, and be biased to engage the master window frame (not shown), without having to use the locking hardware of the window.
- FIG. 14 illustrates the strap member 60 after having been engaged with the pawl member 20 to restrict relative movement of the upper sash 11 and lower sash 12 of a sliding sash window.
- the strap portion 61 of the strap 60 may be inserted through a space between a top rail 14 of a first sash 13 and a bottom rail 12 of a second sash 11 .

- the free end 69 of the strap portion 61 may be inserted into the gap in the pawl member 20 between the strap teeth 33 and intermediate wall 25 , such that the strap teeth 33 of the serrated strap 64 engage the pawl teeth 66 .
- the strap portion 61 may thus be continuously inserted until the engagement edge 38 of the first and second side walls 21 and 22 of the pawl member 20 contacts the bottom rail 12 of the sash 11 .
- the rounded engagement corner 39 may also contact the bottom rail 12 , as the installation of transportation clip assembly 10 may tend to cause slight rotation of the pawl member 20 .
- the lateral support edge 40 and transition edge 43 may contact the lower sash 13 , with such rotation. The existence of, or the amount of, rotation may depend upon the extent of pre-loading that is established.

- the pawl member 20 may be inserted upon the strap member 60 , as seen in FIG. 17 , until the rounded engagement corner 39 contacts the top rail 14 of lower sash 13 .
- the pawl member 20 may then be rotated so that engagement wall 87 of pawl member 20 butts against, the side of the bottom rail 12 of upper sash 11 , while edge 48 of pawl member 20 butts against the top of bottom rail 14 of lower sash 13 . Thereafter, rounded engagement corner 39 and edge 51 may be snapped into the gap between the sashes 11 and 13 .
- Removal of transportation clip assembly 10 is illustrated in FIG. 20 . Removal is accomplished by applying a force to the thin plain strap 67 of strap member 60 , such that it is at an angle 90 relative to portion 26 of intermediate wall 25 of pawl 20 . Application of such a force causes failure of the pawl teeth 33 and of top wall 24 , with release of the strap member 60 from pawl member 20 .
- FIGS. 21 and 22 illustrate an alternate embodiment in which strap member 100 has, instead of strap teeth, a plurality of cylindrical protrusions 101 , each of which has a slanted face 112 oriented so as to face away from the bumper portion.
- the slanted face 112 may engage the protrusion 101 of pawl member 100 to permit deflection of the protrusion 101 , as well as flexing of the strap 110 , with incremental engagement of cylindrical protrusions 111 of strap 100 with orifice 102 of the protrusion 101 .

- the rotation of pawl 120 permits the edge 123 of pawl 120 to engage the top rail 14 of window sash 13 , without necessarily contacting latch 16 , and with second protrusion 127 to be engaged in the gap between the top rail 14 of the lower sash 13 and the bottom rail of the upper sash 11 in a horizontal position.
- This engagement of the second protrusion 127 may serve to prevent counter-rotation of the pawl 120 , which would reduce the preloading of the sashes relative to the master frame.
- the rotation required of the horizontal installation may serve to provide a greater tension force between the window sashes 11 and 13 , which may be needed for transportation of larger and heavier doors and windows.
- Pawl 120 may also comprise, as seen in FIG. 27A , a wall 128 with protruding portion 129 having a plurality of teeth 130 , as well as a wall 131 , which are comparable to the top wall 24 , protruding portion 23 and intermediate wall 25 of pawl 20 .

- the engagement of strap 160 with pawl 120 may occur with engagement of teeth on both sides of the strap 160 to provide a sturdier connection therebetween, which may be beneficial for the horizontal installation where greater loads may be involved.
- the teeth 161 need not be aligned with teeth 162 , and may instead be staggered as seen in FIG. 27A .
- the pawl 120 also has walls 128 and 131 oriented at an angle from wall 121 , with a narrow, necked down region 133 located at the intersection of those walls.
- the neck down region 133 may, be utilized to cause failure of the engagement between strap 160 and pawl 120 by applying a force directly to the pawl 120 , once the sash window or door is ready for installation in a building, and the installer seeks to remove the clip. Alternatively, failure may also be caused by applying a load only to the strap 160 , as was previously discussed.

Abstract
A clip assembly may safely secure sliding sashes of a window or door during transportation, and, in one embodiment, be comprised of a strap member and a pawl member. The strap member may be comprised of a bumper portion, and a strap portion extending therefrom, where the strap portion may have a plurality of teeth formed within the thickness of the strap. The pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall. The top wall may have a protrusion which includes a plurality of pawl teeth formed to complement the strap teeth, and be located proximate to the intermediate wall. The strap may be introduced through the gap between the top rail of an upper sash and bottom rail of the second sash, to then be inserted into the pawl, and thereby be retained by the respective teeth to secure the sashes.
Description
- This application claims priority on U.S. Provisional Application Ser. No. 61/284,244 filed on Dec. 15, 2009, the disclosures of which are incorporated herein by reference.
- The present invention relates to improvements in the means for shipping sliding and tiltable sash windows, and more particularly to apparatus which relieve the stresses imposed on the window's sash locks during transportation.
- There are many different window types available on the market, such as picture windows, bay windows, skylight windows, louvered windows, transom windows, casement windows, and the many versions of the sash window, with those being single-hung, double-hung, vertical sliding, and horizontal sliding sash windows. While the casement window is predominantly used in the United Kingdom and much of Europe, the sliding sash window remains an American favorite for both new construction and for replacement windows.
- Many developments made in sliding sash windows are design changes that relate to improved functionality in the manufacture and/or operation of the windows, particularly with respect to its latches and hinges. However, there has been a long-felt, but unmet, need to improve the traditional methods of safely shipping sliding sash windows.
- To prevent damage to either or both sashes due to uncontrolled sliding, the windows are normally transported with both sashes being latched. However, because of the bouncing and jarring motion including vibrations that are experienced during its transportation, a great deal of stress is placed on the lock and keepers of the window as well as the screws holding the locks and keepers in place. This stress can cause the locks and keepers to become broken or fractured and may also cause the screws to become dislodged from the sash. Such damage can result whether transportation is accomplished using freight cars on a railroad, or by a tractor-trailer on the nation's highways.
- Window manufacturers attempt to address this problem in one of a number of different ways. One way is to insert blocking, made from cardboard, Styrofoam or any number of various packaging-materials, materials, to support the sash windows, while other manufacturers will ship the windows in the closed position but with the sashes unlocked, and with some outer packaging solely relied upon to hold the sashes in place. But this is cumbersome and costly, not only in terms of the purchasing and needed supply of bulky packing materials, but also for its disposal.
- Another method is to open the sash window, and to turn and pack the window upside-down. However, this method creates the potential risk of damage to the window sashes and frame from sliding motion, and furthermore makes the window awkward to maneuver and handle. Another solution is to ship the windows closed and locked, and to use air ride type cargo vans and trailers to reduce the stress to the hardware, with a corresponding increase in shipping costs.
- This invention provides an economical and simple solution for the transportation of sash windows and doors through the use of a serrated strap. There has been some limited use of serrated straps in the art. In U.S. Pat. No. 5,852,852 to Rigal, it was used in combination with a ratchet locking member as a tightening device, with particular applicability for snowboard bindings, roller skates and the like. The Rigal patent improved upon the prior art use of serrated straps, such as those found, for example, in U.S. Pat. No. 5,480,176 to Sims for an externally mounted binding, as well as the Ratchet-type Buckle shown by U.S. Pat. No. 5,416,952 to Dodge. However, all of these types of devices require the use of a separate pivoting ratchet element in combination with the serrated strap.
- U.S. Pat. No. 5,462,542 to Alesi discloses a more simple arrangement in the form of a “Sternum Buckle With Serrated Strap.” The Alesi sternum buckle assembly is adapted to be looped about the split portions of tissue. The serrated strap extends outward from the pawl in a single piece that is formed of a bio-absorbable material. Similarly, in U.S. Pat. No. 3,570,497 to Lemole, the strap has a needle end to penetrate tissue, where retention of the serrations are more simply accomplished by a latch collar, and was intended to be used as a fast means of applying a suture. However, none of these approaches are capable of providing support needed for the safe transportation of a sliding sash window or door.
- Using this invention allows a sash window or door to be shipped with the sashes in the closed position, while remaining unlocked, thus eliminating stress that causes damage to the lock, keeper, and screws.
- It is an object of the invention to provide a means of safely transporting a sliding sash window or door.
- It is another object of the invention to provide a means of safely transporting a sliding sash window or door without the use of bulky packing materials.
- It is a further object of the invention to provide a single means of securing a sliding sash window or door that may universally be utilized by different sized windows and doors.
- It is another object of the invention to provide a means of securing a sliding sash window or door in the closed position without use of the window's lock and keeper.
- It is also an object of the invention to provide a means of securing a sliding sash window or door in the closed position by utilizing the sash window frame.
- The clip assembly of the present invention may be used to secure one or more objects, particularly the sliding sashes of a window or door during transportation, to prevent damage to the sashes or to prevent damage to the lock and keepers when shipped in the locked condition, as well as to obviate the need of using cumbersome cardboard blocking as a restraint.
- The clip assembly may be comprised of two separate molded parts—a strap member and a pawl member. The strap member may be formed to have a bumper portion, and a strap portion extending from the bumper. The bumper may preferably have an engagement wall, and a bottom wall that is supported to be approximately orthogonal to the engagement wall by first and second side walls. The strap portion may have a plurality of teeth formed within the thickness of the strap. The strap teeth may be formed to have an engagement face and a back face, which converge to create a peak, and whereby successive teeth are separated by a trough. Also, the strap portion may terminate in a thinner strap section, with a ramp between the two strap sections, and where the thinner strap section may have a rounded end which may also be ramped to facilitate its insertion into the pawl.
- The pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall. The top wall may have a protrusion which includes a plurality of teeth formed to complement the teeth of the strap, and be located proximate to the intermediate wall. The teeth may be located at a distance from the intermediate wall to permit the strap to be trapped there between, once it is inserted. Insertion of the strap may be accomplished whereby the strap causes deflection of the pawl teeth and the protrusion. This required deflection of the pawl teeth and protrusion may be aided by a recess in the intermediate wall to take advantage of the flexible nature of the strap.
- To restrain a window for transit by truck or rail; a strap of the current invention may be inserted through the gap between the top rail of an upper sash and the bottom rail of the second sash, and then be inserted into the pawl, such that engagement edges of the first and second side walls of the pawl abuts the top rail of the bottom sash. Insertion of the strap into the pawl may occur by inserting the free end of the strap portion into the gap between the strap teeth and the intermediate wall, to engage the pawl teeth until the engagement edge of the first and second side walls of said pawl member firmly contacts the bottom rail of said second sash.

FIG. 2 shows a first embodiment of the present invention, atransportation clip assembly 10, which includes apawl member 20 and astrap member 60.FIG. 1 illustrates thestrap member 60 as it is being inserted into thepawl member 20 to have engagement with, and mono-directional travel relative to, the pawl member.FIG. 3 shows a side view of theclip assembly 10. - The
pawl member 20 andstrap member 60 may be made from any suitable materials, including, but not limited to, plastic. Thepawl member 20 may be formed of various different shapes, but in a preferred embodiment, as shown inFIGS. 4-7 , thepawl member 20 may have afirst side wall 21 and asecond side wall 22, which may be maintained at a set distance bytop wall 24 andintermediate wall 25.First side wall 21 andsecond side wall 22 may be generally parallel to each other, but need not be so oriented. - The thickness of each of the walls may be adjusted to increase the overall strength of the
clip assembly 10. The strength should accommodate most, if not all, sash windows, but could be increased with the aforementioned thickness changes to accommodate larger sliding doors. To encourage commonality, a single sized clip may be utilized for securing various fenestration products, and when it is necessary to secure larger, heavier sliding doors, multipletransportation clip assemblies 10 may be utilized rather than a single stronger clip. - The outer edges of the
first side wall 21 and asecond side wall 22 may have anoutside corner radius 53 around the periphery of the walls to eliminate any sharp edges which might tend to scrape or otherwise damage the finish of the windows. - The periphery of the first and
second side walls side walls engagement edge 38 that may transition into a rounded engagement corner 39 on one end, and into alateral support edge 40 on the other end. These engagement features of theside walls pawl member 20 may bear up against the sashes of the window when engaged by thestrap member 60, as seen inFIG. 14 . - The remaining outer edges of first and
second side walls edges straight edge transition 43 between them, or a rounded corner (not shown), and edges 41 and 42 may have astraight edge transition 44 between them.Edge 42 may connect tangentially to the rounded engagement corner 39 (not shown), or alternatively, there may beedges edge 48 that may be approximately parallel to edge 45.Edge 46 may transition intoedge 48 using anoutside corner 49.Edge 48 may transition into rounded engagement corner 39 by way ofedges edges strap member 50 relative to thepawl member 20, and tightly secure bothsashes FIG. 15A ), as will be discussed hereinafter. In an alternate embodiment, discussed hereinafter, rounded engagement corner 39, and edges 50 and 51 may be seated between window sashes to secure the sashes. - The section view, in
FIG. 8 , throughpawl member 20 reveals thetop wall 24 andintermediate wall 25 as formed in a preferred embodiment.Intermediate wall 25 may be formed to have an axial portion, which as pictured inFIG. 8 appears as ahorizontal wall portion 26 having atop surface 27 and abottom surface 28. Thehorizontal wall portion 26 may transition, by way of acurved region 31, into avertical portion 32. As may be seen hereinafter, thecurved portion 31 may assist in guiding thestrap member 60 to engage with thepawl member 20. Thevertical portion 32 may serve to support theside walls strap member 60 when trying to engage it with thepawl member 20, or as structural support in an alternate embodiment (FIGS. 17-19 ). - The
top wall 24 may span the entirety ofedges second side walls FIG. 8 , only span a portion thereof. Protruding away from thetop wall 24 and towards thetop surface 27 of thehorizontal portion 26 ofintermediate wall 25 may be a triangular-shapedprotrusion 23, which forms agap 50 withtop wall 24, making theprotrusion 23 generally flexible with respect totop wall 24. Triangular-shapedprotrusion 23 may have a plurality ofteeth 33. Although only three teeth are shown inFIG. 8 forpawl member 20, the number of teeth may be increased to provide greater strength in the connection between thestrap member 60 andpawl member 20, which may be required for corresponding increases in wall thicknesses, as previously described. - As seen in the enlarged view of the plurality of
teeth 33 inFIG. 9 , each tooth may be formed to have aback face 35, which meets a front face orengagement surface 36 at the apex 37. Where the back face of one tooth meets the front face of an adjacent tooth may be a tough 34. Theback face 35 andfront face 36 are shown in to be flat inFIG. 9 , with the front face being approximately perpendicular to theintermediate wall 25; however, other possible shapes and orientations may be utilized. The configuration shown may be preferable to assist in the mating of thestrap member 20 with thepawl member 60. The distance between the apex 37 of the plurality ofteeth 33 and thetop surface 27 of thehorizontal portion 26 ofintermediate wall 25 may be crucial to the interconnection between thestrap member 60 andpawl member 20, which is discussed further hereinafter. - The
strap member 60 may be formed to have abumper portion 80 connected to astrap portion 61.Bumper portion 80 may be formed a number of different ways. In one embodiment,bumper portion 80 may be comprised of only anengagement wall 81. However, to help counter unintended rotation of theengagement wall 81 upon installation of thestrap member 60 between first andsecond sashes engagement wall 81 may preferably be connected to abottom wall 84.Bottom wall 84 may preferably be approximately orthogonal toengagement wall 81. This orthogonal relationship betweenbottom wall 84 andengagement wall 81 may be supported by first andsecond side walls - All of the exterior edges of the
bottom wall 84,engagement wall 81, and first andsecond side walls outside corner radius 85. Having the corners thus relieved may serve to prevent scrapes and other facial damages to the windows upon which thetransportation clip assembly 10 may be installed. In addition, theengagement wall 81 may have a cushioning material (not shown) attached thereto to further protect the window. The cushioning material may include, but is not limited to, rubber that is attached to theengagement wall 81 through any acceptable means for the particular cushioning material chosen, including, but not limited to, glue or epoxy. The same cushioning material may also be utilized upon the engagement edges 38 of the first andsecond side walls pawl member 20. - The
strap portion 61 ofstrap member 60 may be comprised of aplain strap 62, which may be connected to theengagement wall 81 of thebumper portion 80 usingfillet radii 63, which may thereby improve the durability of the connection.Plain strap 62, may, but need not, have a rectangular cross-section, having athickness 71. Theplain strap 62 may transition into aserrated strap 64, which may have the same cross-section asplain strap 62, but which further comprises a plurality ofstrap teeth 66, which may be similarly constructed as the plurality ofpawl teeth 33, but formed so as to be complementary in nature to thepawl teeth 33 so as to mesh with and thereby be retained by thepawl teeth 33 ofpawl member 20 when thestrap member 60 is therein inserted. - The plurality of
strap teeth 66 may be formed within thethickness 71 of the cross-section of theserrated strap 64, leaving a narrow portion ofplain strap 64 on each side of thestrap teeth 66, which may not extend to the full width of theserrated strap 64. - Proper functional engagement of the plurality of
strap teeth 66 with the plurality ofpawl teeth 33 is obtained through careful control of several features and dimensions. As previously stated, the distance between theapexes 37 of the plurality ofteeth 33 ofpawl 20 from thetop surface 27 of thehorizontal portion 26 ofintermediate wall 25 may be crucial to this functional engagement. Proper engagement may generally depend upon trapping theserrated strap 64 against thetop surface 27 of thehorizontal portion 26 ofintermediate wall 25. Snugly trapping theserrated strap 64 may preferably require a combination of deflection of theprotrusion 23 and deflection of theserrated strap 64 when feeding thestrap member 60 intopawl member 20. - Deflection of the
protrusion 23 may occur when thestrap teeth 66 contact thepawl teeth 33 resulting in an applied load to the protrusion and causing angular deflection at the gap 50 (FIG. 9 ) towards thetop wall 24. This invention furthermore takes advantage of the flexural nature of thestrap portion 61 when being inserted into thepawl member 20, through its tendency to bend or even buckle under compression loading, by incorporating arecess 29 in thetop surface 27 of thehorizontal portion 26 of theintermediate wall 25. Therecess 29 may necessitate the use of astep 52 in thelower surface 28 of thehorizontal portion 26 ofintermediate wall 25 to increase thickness, in order to accommodate the thickness reduction due to therecess 29. - The
recess 29 allows theserrated strap 64 region ofstrap 60 to deflect downward, under the compression loading, away from the plurality ofteeth 33 of thetriangular protrusion 23, as thetriangular protrusion 23 andteeth 33 simultaneously deflect upward. Therecess 29 may havecurved transitions 51 with thetop surface 27 of theintermediate wall 25 to facilitate bending of thestrap 60 in proximity to the plurality ofteeth 33 of thepawl 20. Therecess 29 may preferably have a maximum depth such the distance between the apex of theteeth 33 of thepawl 20 and therecess 29 is approximately equal to saidthickness 71 of the strap. - It may be seen that loading of the
strap 60 in tension relative to thepawl 20, bysash windows 11 and 13 (FIG. 14 ), may cause theprotrusion 23 with the plurality ofteeth 33 to deflect downward and trap thestrap 60 against thetop surface 27 of thehorizontal portion 26 ofintermediate wall 25. The downward deflection ofprotrusion 23 with the plurality ofteeth 33 would not permit therecess 29 to facilitate disengagement of theserrated strap 64 from thepawl 20, the way therecess 29 facilitates engagement. - Initial engagement of the
strap 60 with thepawl 20 may be furthered by having aplain strap section 67 which may be thinner thanplain strap 62, and may transition to theserrated strap 64 using aramp 68. The thinplain strap 67 may terminate in a tapered and rampedend 69. The tapered/rampedend 69 may have anorifice 70 which may be used in conjunction with a tool (not shown) to apply tension to thestrap 60 relative to thepawl 20, to pre-load thewindow sashes upper sash 11 will be loaded towards the upper portion of themaster frame 15, with a corresponding loading of thelower sash 13 towards the lower portion of the master frame. The tool may have a prong that retains theorifice 70 and allows thestrap portion 61 to be rolled up on the tool, and whereby the roll may act against theedges second side walls pawl 20. The ability to apply such tension between thepawl member 20 and thestrap member 60 permits further engagement of one or more of thepawl teeth 33 with saidstrap teeth 66 to generate the pre-loaded sash arrangement. Thepre-loaded window sashes -
FIG. 14 illustrates thestrap member 60 after having been engaged with thepawl member 20 to restrict relative movement of theupper sash 11 andlower sash 12 of a sliding sash window. As seen inFIG. 14 , thestrap portion 61 of thestrap 60 may be inserted through a space between atop rail 14 of afirst sash 13 and abottom rail 12 of asecond sash 11. Theengagement wall 81 of thepawl 20 may abut thetop rail 14 of saidbottom sash 13. Thefree end 69 of thestrap portion 61 may be inserted into the gap in thepawl member 20 between thestrap teeth 33 andintermediate wall 25, such that thestrap teeth 33 of theserrated strap 64 engage thepawl teeth 66. - The
strap portion 61 may thus be continuously inserted until theengagement edge 38 of the first andsecond side walls pawl member 20 contacts thebottom rail 12 of thesash 11. The rounded engagement corner 39 may also contact thebottom rail 12, as the installation oftransportation clip assembly 10 may tend to cause slight rotation of thepawl member 20. In addition, thelateral support edge 40 andtransition edge 43 may contact thelower sash 13, with such rotation. The existence of, or the amount of, rotation may depend upon the extent of pre-loading that is established. - An alternate installation embodiment is shown in
FIGS. 15A through 15C for a sliding sash window, and inFIGS. 16A and 16B for a tiltable/slidable sash window. For both window types, thebumper portion 80 of thestrap member 60 may be fed between the two sashes, while the sash is slid open or tilted open. The engagement wall 87 of thebumper portion 80 of thestrap member 60 of may then rest up against thebottom rail 12 of theupper sash 11. Thepawl member 20 may be inserted upon thestrap member 60, as seen inFIG. 17 , until the rounded engagement corner 39 contacts thetop rail 14 oflower sash 13. Thepawl member 20 may then be rotated so that engagement wall 87 ofpawl member 20 butts against, the side of thebottom rail 12 ofupper sash 11, whileedge 48 ofpawl member 20 butts against the top ofbottom rail 14 oflower sash 13. Thereafter, rounded engagement corner 39 andedge 51 may be snapped into the gap between thesashes - Removal of
transportation clip assembly 10 is illustrated inFIG. 20 . Removal is accomplished by applying a force to the thinplain strap 67 ofstrap member 60, such that it is at an angle 90 relative toportion 26 ofintermediate wall 25 ofpawl 20. Application of such a force causes failure of thepawl teeth 33 and oftop wall 24, with release of thestrap member 60 frompawl member 20. - An alternate embodiment of the current invention is shown in
FIGS. 22 through 24 .FIGS. 21 and 22 illustrate an alternate embodiment in whichstrap member 100 has, instead of strap teeth, a plurality ofcylindrical protrusions 101, each of which has a slantedface 112 oriented so as to face away from the bumper portion. Theslanted face 112 may engage theprotrusion 101 ofpawl member 100 to permit deflection of theprotrusion 101, as well as flexing of thestrap 110, with incremental engagement of cylindrical protrusions 111 ofstrap 100 withorifice 102 of theprotrusion 101. - In another alternate embodiment, shown in
FIG. 25 , thestrap 107 transitions from a thin flat strap portion into an externally threadedcylindrical portion 108 that is received by internal threading on thepawl 105. Thepawl 105 may have aswivel end 106 to permit rotational engagement of the threadedportion 108 of thestrap 107 without rotation of thepawl 105 at therail 14 ofwindow 13. - In
FIGS. 26 and 27 , an alternate embodiment is shown with apawl 120, which may be utilized for two different installation configurations. Thepawl 120 may have resemblepawl 20 with itsengagement edge 38, rounded engagement corner 39,edge 48, andlateral support edge 40, butpawl 120 may instead have anengagement edge 122 connected toedges rounded engagement protrusion 127 may be located whereengagement edge 122 connects to edge 123, and asecond protrusion 126 may be located whereedge 122 connects to edge 121. - The
protrusions FIG. 28 , thepawl 120 may engage thealternative embodiment strap 160 and be tensed therebetween such that theedge 122 ofpawl 120 engages thetop rail 14 ofwindow sash 13, without contactinglatch 16. Theprotrusion 126 may thereby be engaged in the gap between thetop rail 14 of thelower sash 13, and the bottom rail of theupper sash 11, to assist in securing the clip assembly to the window sashes. Alternatively, as seen on the left side ofFIG. 28 , thepawl 120 may engage thestrap 160 withedge 122 coming in close proximity totop rail 14 oflower sash 13, but not necessarily making contact therebetween, as thepawl 120 may then be rotated, as was illustrated inFIGS. 17 and 18 . The rotation may serve to provide additional loading of the sashes relative to the master frame, with the loading of one sash being in a direction opposite to the loading of the second sash. - The rotation of
pawl 120 permits theedge 123 ofpawl 120 to engage thetop rail 14 ofwindow sash 13, without necessarily contactinglatch 16, and withsecond protrusion 127 to be engaged in the gap between thetop rail 14 of thelower sash 13 and the bottom rail of theupper sash 11 in a horizontal position. This engagement of thesecond protrusion 127 may serve to prevent counter-rotation of thepawl 120, which would reduce the preloading of the sashes relative to the master frame. The rotation required of the horizontal installation may serve to provide a greater tension force between thewindow sashes -
Pawl 120 may also comprise, as seen inFIG. 27A , awall 128 with protrudingportion 129 having a plurality ofteeth 130, as well as awall 131, which are comparable to thetop wall 24, protrudingportion 23 andintermediate wall 25 ofpawl 20. However, inpawl 120,wall 131 also may have a plurality ofteeth 132. Also, thestrap member 160 may have a serrated strap portion with a plurality ofteeth 161 on one side of thestrap 160 to engage theteeth 130 on protrudingportion 129, as well as a plurality ofteeth 162 on the opposite side to engage theteeth 132 ofwall 131. Therefore, the engagement ofstrap 160 withpawl 120 may occur with engagement of teeth on both sides of thestrap 160 to provide a sturdier connection therebetween, which may be beneficial for the horizontal installation where greater loads may be involved. Theteeth 161 need not be aligned withteeth 162, and may instead be staggered as seen inFIG. 27A . - The
pawl 120 also haswalls wall 121, with a narrow, necked downregion 133 located at the intersection of those walls. The neck downregion 133 may, be utilized to cause failure of the engagement betweenstrap 160 andpawl 120 by applying a force directly to thepawl 120, once the sash window or door is ready for installation in a building, and the installer seeks to remove the clip. Alternatively, failure may also be caused by applying a load only to thestrap 160, as was previously discussed. - The examples and descriptions provided merely illustrate a preferred embodiment of the present invention. Those skilled in the art and having the benefit of the present disclosure will appreciate that further embodiments may be implemented with various changes within the scope of the present invention. Other modifications, substitutions, omissions and changes may be made in the design, size, materials used or proportions, operating conditions, assembly sequence, or arrangement or positioning of elements and members of the preferred embodiment without departing from the spirit of this invention.
