1. Field of the Invention
The disclosure relates generally to sealing systems for use with panels, such as a door or a window, within a frame and, more specifically, to a sealing system for providing an improved seal between a panel and frame.
2. Description of the Related Art
Certain types of panels, such as doors and windows, are positioned within openings of a wall and/or other structures using a frame. These panels may also open and close by pivoting relative to the frame. An issue associated with these types of panels is the integrity of the seals between the panels and the frame. In many instances, these seals are an insufficient barrier in preventing the transfer of such environmental elements as noise, weather, water, and insects from one side of the panel to the other side.
Attempts have been made to address these issues by using various types of weather stripping between the panels and frame. For example, the weather stripping may be strip of felt, foam, or a pile of flexible synthetic material. In many instances, however, this weather stripping fails to act as a sufficient seal between the panels and frame. Another issue prevalent associated with the seals between a frame and panel or between adjacent panels is that these seals can become disjoined. Either intentionally or unintentionally, the alignment between the frame and panel or between adjacent panels may be disturbed which can degrade the quality of the seal, since, in many instances, the integrity of the seal relies upon these members having certain positional relationships relative to one another.
There is, therefore, also a need for a sealing system that maintains the positional relationships between the frame and panel. A need also exists for a sealing system that can be employed between a frame and panel that prevents the transfer from one side of the panel to the other side of the panel such environmental effects as noise, weather, water, heat/cold, and insects
Embodiments of the invention address deficiencies of the art with respect to effectively creating a seal between a panel and a frame. In this regard, a combined sealing system and seal activation system for use with a double door/window system having a first panel and a second panel includes a first sealing system and a first seal activation system. The first sealing system is positioned within a meeting stile of the first panel, and the first seal activation system activates the first sealing system. The first sealing activation system is also positioned within a meeting stile of the second panel and includes a movable member configured to engage the first sealing system. The first sealing system includes a movable member, and movable member of the first sealing system is caused to move towards the second panel by the first sealing system being engaged by the movable member of the first seal activation system moving towards the first panel. The first panel and the second panel separately pivot relative to a frame surrounding the double door/window system.
In certain aspects of the combined sealing system and seal activation system, the first sealing system includes a rocker arm pivotally connected to the first panel, and an anchor pivotally connected to the rocker. Movement of a portion of the rocker arm away from the second panel moves the anchor towards the second panel. The first seal activation system includes a first cam pivotally connected to the second panel, and a first activation pin pivotally connected to the first cam. The anchor of the first sealing system is caused to move towards the second panel by the first sealing system being engaged by the first activation pin moving towards the first panel.
In other aspects of the combined sealing system and seal activation system, a plurality of sealing systems are provided to respectively connect all pairs of adjacent sides of the frame and the first and second panels. Also, the first sealing system provides a seal substantially, entirely between the meeting stile of the first panel and the meeting stile of the second panel. In a locked configuration of the first sealing system, the anchor engages a portion of the second panel to form a seal between the first panel and the second panel and to prevent movement of the first panel relative to the second panel.
In further aspects of the combined sealing system and seal activation system, a second sealing system is positioned within the frame, and the second seal activation system activates the second sealing system and is positioned within the second panel on one side of the second panel. The first sealing activation system is positioned within the second panel on another side of the second panel different than the one side of the second panel. The first cam and a second cam of the second activation system are interconnected via at least one cam connecting member, and positioning the first seal activation system to an engaged configuration causes positioning of all seal activation systems to an engaged configuration.
In yet other aspects of the combined sealing system and seal activation system, a second sealing system is positioned within the frame, and the first seal activation system activates the second sealing system. The first sealing system includes an extension arm pivotally connected to the rocker arm and is configured to transfer motion of the first activation pin to the rocker arm. A plurality of rocker arms are connected to the anchor, and in the locked configuration of the first sealing system, the first activation pin extends through the anchor.
In still other aspects a combined sealing system and seal activation system is provided for use with a first panel of a door/window system. The combined system includes a first seal activation system positioned within the first panel, and a second sealing system positioned within the first panel. The first seal activation system activates a first sealing system positioned within a frame surrounding the door/window system. Also, the first seal activation system has an engaged configuration and a disengaged configuration while the first panel is positioned within the frame. The second sealing system creates a seal between the first panel and one of a second panel and the frame, and the second sealing system having a locked configuration and an unlocked configuration while the first panel is positioned within the frame.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
The frame 120 may include a header 130, jambs 140, and a sill 150. A header 130 is a structural member that spans an upper portion of the window/door opening. Jambs 140 are the outermost vertical side members of the frame 120. A sill 150 is a threshold or structural member that spans a lower-most portion of the window/door opening. As recognized by those skilled in the art, different terms may also be associated with the above-structure identified as the header 130, jambs 140, and sill 150.
The panel 110 may include a sash 160 that surrounds a pane 170. The pane 170 is not limited as to a particular material. For example, the pane 170 may be translucent, such as glass or plastic, opaque, such as with wood or metal, or any combination thereof. The sash may include a header rail 175, jamb or stile rails 180, and a sill rail 185. As recognized by those skilled in the art, different terms may also be associated with the structure identified as the header rail 175, the jamb or stile rail 180, and sill rail 185.
Referring to
Although the present door/window system 100 is described herein with particular types of sealing systems 200 being positioned in particular locations in the frame 120, the door/window system 100 is not limited as to a particular type of sealing system 200 and/or a particular location of the sealing system 200 within the frame 120. Additionally, although the present door/window system 100 is described herein with particular types of seal activation systems 205 being positioned in particular locations in the panel 110, the door/window system 100 is not limited as to a particular type of seal activation system 205 and/or a particular location of the seal activation system 205 within the panel 110.
To prevent the forced opening of the panel 110, the sealing systems 200 are not limited as to a percentage of coverage between particular members of the frame 120 and/or panel 110. For example, the sealing systems 200 may only cover a fractional number (e.g., 10%, 50%, 85%) of the length between particular members of the frame 120 and/or panel 110. However, in certain aspects, the sealing systems 200 provide substantially complete coverage between the sash 160 of a panel 110 and the frame 120. In so doing, the combined sealing systems 200 can provide a seal substantially, completely around the panel 110.
A closing system 300 moves the seal activation system 205 from the deactivated configuration (see
At least one of the seal activation systems 205 may include at least one cam 210, 215. Although not limited in this manner, the cam 210, 215 can be fixed in position relative to the panel 110 by being rotated about a cam pivot 290 connected to the panel 110. Upon being rotated, the cam 210, 215 causes the movement of at least one activation pin 225. For example, upon being rotated in one direction, the cam 210, 215 may cause the movement of the activation pin 225 away from the sash 160, and upon being rotated in the opposite direction, the cam 210, 215 may cause the movement of the activation pin 225 towards the sash 160. Either directly or indirectly, depending upon the type of movement of the activation pin 225, the activation pin 225 positions the sealing system 200 in the locked configuration and/or the unlocked configuration.
Each cam 210 may move a single or multiple activation pins 225. For example, as illustrated in the drawings, a side cam 210 may be connected to single activation pin 225. As another example, a corner cam 215, by being positioned in a corner of the panel 110, may be connected to two activation pins 225 with each activation pin 225 extending from separate sides of the sash 160.
Although not limited in this manner, multiple cams 210, 215 may be provided along a single side of the sash 160. In so doing, the multiple cams 210, 215 may cause the activation of multiple sealing systems 200 positioned within a single side of the frame 120 adjacent the single side of the sash 160.
The seal activation system 205 may also include one or more cam connecting members 220 for interconnecting some or all of the cams 210, 215. In this manner, rotation of one of the cams 210, for example by the closing system 300, causes the other cams 210 to rotate. A single closing system 300 may be configured to simultaneously move each of separate seal activation systems 205 via, for example, use of the cam connecting members 220. However, in other aspects of the door/window system 100, multiple closing systems 300 may be provided to separately close one or multiple seal activation systems 205.
Both the cam connecting member 220 and/or the activation pin 225 may be connected to the cams 210, 215 via separate cam slot pivots 209. The cam slot pivot 209 may also allow the cam connecting member 220 and the activation pin 225 to pivot relative to the cams 210, 215. The cams 210, 215 may also include a cam slot 207 through which the cam slot pivot 209 may extend. The cam slot 207 allows the cam slot pivot 209 connecting the cams 210, 205 to either the activation pin 225 or the cam connecting member 220 to laterally slide relative to the cam 210, 215. As the cams 210, 215 rotate, the angular and/or positional relationship between the cams 210, 215 and the activation pin 225 and/or the cam connecting member 220 change. The cam slot 207 allows for easier pivoting of the cams 210, 215 relative to the activation pin 225 and/or the cam connecting member 220 by providing the cam slot pivot 209 additional positional flexibility.
Although the combination of cams 210, 215, cam connecting members 220, and activation pins 225 described and illustrated are one example of how a seal activation system 205 within the panel 110 may activate a sealing system 220 within the frame 120, the door/window system 100 is not limited in this particular manner. As can be readily envisaged by one skilled in the art, other types of linkages systems may be employed to act as a seal activation system 205 within the panel 110 to activate the sealing system 220 within the frame 120.
In certain aspects of the sealing system 200, the sealing system 200 employs the use of reciprocal motion device to form a seal 230 between adjacent members of sash 160 and the frame 120. The seal 230 is formed by engagement of an anchor 250 of the sealing system 200 with a portion of the sash 160. Although the sealing system 200 is not limited as to the particular portion of the sash 160 with which the anchor 250 engages to form the seal 230, in certain aspects of the sealing system 200, the seal 230 engages a surface of a slot 240 within members (e.g., header rail 175, stile rail 180, and sill rail 185) of the sash 160. Also, by having the anchor 250 being positioned with slot 240, movement of the panel 110 relative to the frame 120 can be prevented.
Additionally, as shown in
One or more anchor guides 285 may extend from the frame 120 and through the anchor 250. In so doing, the anchor guide 285 can guide movement of the anchor 250 along a predetermined path and prevent the anchor 250 from deviating from the predetermined path. This function of guiding the anchor 250 may also be provided by one or more activation pins 225 that extend from the sash 160. The activation pin 225 may be positioned to pass through the anchor 250 while engaging the sealing system 200 as will be described in greater detail below. In so doing, the activation pin 225 may also guide movement of the anchor 250 along a predetermined path and prevent the anchor 250 from deviating from the predetermined path.
The reciprocal motion device to form the seal 230 includes a pair of motions in opposite directions. For example, one of the motions may involve the movement of the anchor 250 substantially towards the sash 160, and the second of the motions may involve the movement of a portion of the sealing system 200 substantially away from the sash 160. The manner in which the reciprocal motion is created is not limited as to a particular device. For example, many types of linkages are known that are capable of transforming motion in one direction to direction in a substantially opposite direction.
In certain aspects of the sealing system 200, the reciprocal motion is created through the use of a rocker arm 260 that pivots about a rocker pivot 270. Although not limited in this manner, the rocker pivot 270 may be attached to a rocker housing 255 and/or the frame 120, and one side of the rocker arm 260 may be connected, either directly or indirectly, to the anchor 250. Although not limited in this manner, an anchor pivot 275 connects the rocker arm 260 to the anchor 250 and allows the rocker arm 260 to pivot relative to the anchor 250.
The movement of the anchor 250 may be accomplished through the use of repetitive portions of the sealing systems 200. For example, multiple rocker arms 260 may be attached to a single anchor 250. In so doing, the force used to move the anchor 250 may be balanced through the use of the multiple rocker arms 260.
Movement of the opposite side of the rocker arm 260 substantially away from the sash 160 creates the reciprocal movement of the side of the rocker arm 260 connected to the anchor 250 substantially towards the sash 160. This results in the anchor 250 moving substantially towards the sash 160. The sealing system 200 is not limited in the manner in which the opposite side of the rocker arm 260 is moved substantially away from the sash 160. Many types of devices so capable are known in the art, and the sealing system 200 is not limited as to a particular type of device so capable.
In certain aspects of the sealing system 200, however, the rocker arm 260 is configured to be moved by a movable member extending from the sash 160. The sealing system 200 is not limited as to a particular type of movable member extending from the sash 160 that is capable of moving the rocker arm 260 in a direction away from the sash 160; however, in certain aspects, the movable member is an activation pin 225. The movable member (e.g., the activation pin 225) may engage, either directly or indirectly, the rocker arm 260.
As illustrated in the figures, in a current aspect of the sealing system 200, an extension arm 280 may be provided to indirectly connect the rocker arm 260 to the movable member used to move the rocker arm 260. As shown in
One or more extension guides 281 may extend from the frame 120 and through the extension arm 280. In so doing, the extension guides 281 can guide movement of the extension arm 280 along a predetermined path and prevent the extension arm 280 from deviating from the predetermined path. The extension guides 281 may also prevent the extension arm 280 from floating within the rocker housing 255 and/or maintain a desired relationship between the extension arm 280 and the rocker arm 260.
Although not limited in this manner, an extension arm pivot 282 connects the rocker arm 260 to the extension arm 280 and allows the extension arm 280 to pivot relative to the rocker arm 260. The rocker arm 260 may also include a rocker slot 284 through which the extension arm pivot 282 and/or the rocker pivot 270 may extend. The rocker slot 284 allows either the extension arm pivot 282 and/or the rocker pivot 270 to laterally slide relative to the rocker arm 260 and allow for easier pivoting of the rocker arm 260 relative to the extension arm 280 and/or the frame 120.
The sealing systems 200 are not limited as to the particular manner in which the sealing system 200 is positioned from the locked configuration to the unlocked configuration. For example, after the anchor 250 has been moved towards the sash 160 and the member has been withdrawn from engagement with the rocker arm 260, a resilient member (or other device) may move (either directly or indirectly) a portion of the rocker arm 260 attached to the anchor 250 away from the sash 160. In addition to or alternatively, the resilient member (or other device) may be directly connected to the anchor 250. As previously described, the engagement of one sealing system 200 may cause the engagement of one or more of the other sealing systems 200. In the same manner, the disengagement of one sealing system 200 may cause the disengagement of one or more of the other sealing systems 200.
Another version of the sealing system 200 employing a reciprocal motion device is illustrated in
The frame 120 may include a header 130, jambs 140, and a sill 150. A header 130 is a structural member that spans an upper portion of the window/door opening. Jambs 140 are the outermost vertical side members of the frame 120. A sill 150 is a threshold or structural member that spans a lower-most portion of the window/door opening. As recognized by those skilled in the art, different terms may also be associated with the above-structure identified as the header 130, jambs 140, and sill 150.
Each panel 110A, 110B may include a sash 160 that surrounds a pane 170. The pane 170 is not limited as to a particular material. For example, the pane 170 may be translucent, such as glass or plastic, opaque, such as with wood or metal, or any combination thereof. The sash may include a header rail 175, a jamb or stile rail 180, a sill rail 185, and a meeting stile 190. As recognized by those skilled in the art, different terms may also be associated with the structure identified as the header rail 175, the jamb or stile rail 180, the sill rail 185, and the meeting stile 190. The respective jamb/stile rails 180 of the panels 110A, 110B that adjoin one another when the double door/window system 100 is closed are also know as meeting stiles 190.
Referring to FIGS. 16 and 17A-17E, the combination sealing system 200 and seal activation system 205 may be used with each of the members 175, 180, 185, 190 of the sash 160 to form a seal 230 (see
Although the present double door/window system 100 is described herein with particular types of sealing systems 200 being positioned in particular locations in the frame 120, the door/window system 100 is not limited as to a particular type of sealing system 200 and/or a particular location of the sealing system 200 within the frame 120. Additionally, although the present door/window system 100 is described herein with particular types of seal activation systems 205 being positioned in particular locations in the panels 110A, 110B, the door/window system 100 is not limited as to a particular type of seal activation system 205 and/or a particular location of the seal activation system 205 within the panels 110A, 110B. For example, although sealing systems 200 are shown as being positioned in the meeting stile 190 of the first panel 110A and seal activation systems 205 are shown as being positioned in the meeting stile 190 of the second panel 110B, this positioning can be reversed such that sealing systems 200 are positioned in the meeting stile 190 of the second panel 110B and seal activation systems 205 are positioned in the meeting stile 190 of the first panel 110A.
To prevent the forced opening of the panels 110A, 110B, the sealing systems 200 are not limited as to a percentage of coverage between particular members of the frame 120 and/or panels 110A, 110B or between the meeting stiles 190 of the panels 110A, 110B. For example, the sealing systems 200 may only cover a fractional number (e.g., 10%, 50%, 85%) of the length between particular members of the frame 120 and/or a particular panel 110A, 10B or of the length between the meeting stiles 190. However, in certain aspects, the sealing systems 200 provide substantially complete coverage between the sash 160 of a particular panel 110A, 110B and the frame 120 and substantially complete coverage between the meeting stiles 190 of the panels 110A, 110B. In so doing, the combined sealing systems 200 can provide a seal substantially, completely around and between the panels 110A, 110B.
