The present invention relates generally to the field of fasteners and anchors, especially useful in the building industry for various tasks, such as, e.g., securing windows and doors to surrounding support framing in buildings, and the like. More particularly, the present invention relates to a combined anchor and fastener assembly wherein both functions of anchoring and fastening are achieved by the provision of a relatively simple, yet highly effective combined anchor and fastener assembly. The assembly comprises a baseplate or flange attached to a post depending therefrom in the form of a screw or bolt having a threaded blind bore formed therein for anchoring objects to a support structure which affords a strong and robust joint allowing easy, facile and quick installation and also affords watertight performance.
Various methods for mounting and waterproofing, a variety of items, such as solar panels and railings to roofs and terraces or windows, doors, or the like to, are well known but prove to be crude and insufficient over time. In the window and door industry, there are often issues with water infiltration at the points of attachment of the windows and doors to the building framing. While conventional pan flashing may be installed below the window or door in order to collect and direct any water that may leak through or around the window or door opening to the exterior, water infiltration may still occur at the points of attachment of the pan flashing to the building framing. Accordingly, it is difficult for many of the installers to provide guarantees or obtain insurance against water or moisture damage caused by conventional window or door anchoring systems.
In Applicant's U.S. application Ser. No. 15/852,733, Applicant addressed this problem by the provision of a novel anchor and fastening assembly especially intended for mounting and waterproofing roof equipment, accessory structures or the like, such as solar panels, HVAC equipment and roof railings etc. on roofs, roof decks, balconies and the like, comprising an anchor baseplate and a post depending therefrom, the latter of which is receivable into or through the intended “anchoring” structure support a at least partially threaded blind bore passes through the baseplate and into the post. A fastener, such as a bolt, is receivable in the blind bore for fastening an object to the assembly. As mentioned above, the assembly can be used to secure, e.g., a solar panel, HVAC or other roof equipment to a roof or other building structure. The present invention provides an improvement to this novel anchor and fastener assembly, especially intended for windows and doors by configuring the post as a one-piece screw or bolt anchor while still affording a strong and robust joint and watertight performance.
Accordingly, it is an object of the present invention to provide a novel anchoring system which addresses and solves such problems in the prior art systems as noted above in an advantageous, effective and facile manner.
It is a further object of the invention to provide a novel anchor assembly which is more reliable than prior art systems in providing a waterproof connection at the attachment points.
It is another object of the present invention to provide a novel one-piece anchor assembly which is relatively simple in design and construction, easy and quick to install, and is relatively inexpensive to make.
It is an object of the present invention to provide a novel anchor assembly especially useful in the building industry for a variety of support and connection tasks, such as, e.g., for anchoring windows and doors into openings formed in a building's framing or hanging shutters and the like and providing waterproof protection at the attachment points.
Certain of the foregoing and related objects are readily attained according to the present invention by the provision of a combined anchor and fastener assembly for anchoring an object to a support structure, comprising an anchor baseplate having a top surface and a bottom surface, an elongated post having an upper end and lower end, with said upper end thereof coupled to said baseplate so it depends from said bottom surface thereof, and an at least partially threaded blind bore extending from said top surface of said baseplate into said post, and having an open top end in said top surface of said baseplate and a closed bottom end in said post, with said bottom surface of said anchor baseplate being configured to allow at least a portion of the support structure to abut and lie generally flush thereagainst except for the area of said bottom surface which is covered by post.
In preferred embodiments of the present invention the post comprises either an at least partially threaded screw or bolt. Advantageously, the anchor baseplate comprises a flange and desirably the flange is a generally circular, planar flange.
In a further preferred embodiment, a polygonally-shaped nut having a throughbore is affixed to the top surface of said baseplate with its throughbore in axial alignment and registry with said blind bore of said baseplate. The polygonally-shaped nut is a preferably hexagonally shaped nut.
In another preferred embodiment, the anchor includes an elongated tubular neck portion having a throughbore with an open top end and open bottom end, and wherein said bottom open end thereof is affixed to said top surface of said baseplate with its throughbore in axial alignment and registry with said blind bore of said baseplate. Desirably, the throughbore of said neck portion is at least partially threaded. Most desirably, the blind bore has a longitudinally-extended axis and the assembly additionally includes means for rotating said anchor about said axis of said blind bore. Most advantageously, said means for rotating comprises a port formed adjacent to and within said open top end of said elongated neck portion which is configured and dimensioned to accommodate a tool for rotating said anchor into a support structure.
Alternatively, said means for rotating comprises a port formed adjacent to and within said open top end of said blind bore. The port can be configured and dimensioned as a flat head screw slot or as an Allen key port.
In a particularly preferred embodiment of the present invention, the assembly additionally includes means for fastening an object to said anchor baseplate via said blind bore, preferably, a threaded bolt, and means for fastening said anchor baseplate to the support structure with said bottom surface thereof lying generally flush against at least a portion of the support structure except for the area of said bottom surface covered by said post, which advantageously comprises a nut.
Other objects and features of the present invention will become apparent from the detailed description considered in connection with the accompanying drawings, which disclose several embodiments of the invention. It is to be understood that the drawings are to be used for the purpose of illustration only and not as a definition of the limits of the invention.
Turning now in detail to the drawings and, in particular,
Bore 117 in screw 116 is a blind bore having an open top end defined by the bore 114 in flange or baseplate 111 and a closed bottom end 119 in the shaft of screw 116. It is also preferred that screw 116 and baseplate 111 are integrally joined to form a one-piece combined anchor and fastener assembly or component. Screw 116 can be secured to baseplate 111 via welding, a press-fit connection or by any other fastening means that would insure that screw 116 and baseplate 111 are securely and rigidly fastened together to provide a strong and robust anchor.
As will be shown and discussed hereinafter in relationship to the installation and use of the anchors, of the present invention for this embodiment and the other embodiments described herein, a fastener typically in the form of a bolt 26 having an enlarged head and a threaded shaft together with a washer 27 is threadably receivable in the bore 117 to hold and securely fasten an object to the anchor so that the object, or part thereof or an associated accessory structure therefor, such as the U-shaped bracket used to support a glass panel for a roof railing shown in Applicant's parent application Ser. No. 15/852,733, is securely held fast against the upper surface of anchor baseplate 111. This is accomplished by providing a through-hole in the object, part or accessory structure therefor through which the threaded shaft of the bolt is passed through before it is threaded into the bore 117 or the like of the anchor and tightened to securely fasten the object to the anchor.
The Allen key port 133 comprises a cylindrical metallic plug secured in head space 145, preferably via welding bore 117. The cylindrical plug 133 has inner wall 132 defining a preferably hexagonal central bore which serves as an Allen key port and is configured to receive an Allen key (not shown) by which the flush screw anchor 110 can be easily and threadably screwed into, and removed from, the door frame, window frame or other support, as described and illustrated in greater detail hereinafter.
In a second embodiment of the present invention, as shown in
Turning now to
The neck 350 is preferably substantially cylindrical, but is not limited to any particular geometrical shape as discussed further below. As shown best in
Turning now to
Two similarly configured T-shaped bores 23 are provided on the inner surface of the jamb side rails 24 of the window frame 21 for effecting receipt of the head of bolt 26 and washer 27 in the upper enlarged well thereof and with the shaft of bolt 26 received through the lower bore portion into the blind bore 217 of the hex head screw anchor 210 (shown in exploded view) and the flush screw anchor therebelow (shown fully installed). As a result of the use of a hex head screw anchor 210, the jamb 24 of the window frame 21 is spaced from the building frame jamb 34 to optionally allow the provision of shims (not shown) in this intermediate space between jambs 24, 34 to level the window (or door) as may be needed during installation.
Anchor assemblies 110 and 210 are utilized to mount and secure a window or door 21 frame to a building frame 22, which may, be wood, metal, concrete, composite construction material, or the like, as is standard or conventional in the industry. The shafts 116 and 216 of the screw anchors 110 and 210, respectively are configured and dimensioned to be screwed into the building's window or door framing 21 at desired locations, such as on the bottom sill 32 and side jamb 34 of the building framing, until lower side 113 of baseplate 111 is in flush abutting contact with the bottom plate 32 and jack stud 34 of the building frame 31 defining the window or door opening frame.
In other situations, it may be desirable to also utilize conventional window and door sill waterproof pan flashing (not shown). In installations where sill pan flashing is utilized, the flashing overlies the window or door sill 32 supporting the window frame 21. Anchors 110, 210 are screwed through the pan and into building frame 32, so that lower surface 113, 213 of baseplate 116, 216 overlies the pan. When a metal pan is utilized, it may be preferable to weld or solder the lower surface 113 of baseplate 111, 211 to the pan.
Alternatively, as shown in
Once the anchor assemblies 110, 210 are fastened into their desired locations on the building framing 32 for the door or window, with gasket or sealant 35, bolts 26 are inserted into bores 114, 117 of anchors 110 and 210. The installer has the option of loose laying the window or door frame 21 within the building or wall frame 31 on top of bolts 26 that are temporarily received in bores 117, 217 of anchors 110, 210. The bolts 26 are turned, such as with a crescent wrench, to their desired leveling height. Shims (not shown) are then inserted between the pan or baseplate 116, 216 and window frame 21, to level the door or window 200. The window or door is then removed from the building framing 31 and bolts 26 are unscrewed from anchors 110, 210. The window or door is then returned into the framing opening 21 on top of the shims (not shown). Bolts 26 are then inserted through the recessed openings 23 formed in the window or door frame 21 and into the internally-threaded central bores 117, 217 of shaft 116, 216 and tightened, to secure the window or door frame 21 in place. Depending on the size of the window frame 21, multiple anchor assemblies may be utilized and their exact size and placement will depend on the application.
As can be appreciated from
As shown in
Please note that the sheathing may be wood, metal, concrete, composite construction material, or the like, as is standard or conventional in the industry. Consequently, shaft 316 of anchor 310 is configured and dimensioned to be screwed into the building's wall sheathing or building frame 50 and optional wall membrane 51 so that the open end of the extended long neck 322 lies generally flush with the outer surface of the stucco layer 52. As shown in
As shown in
More particularly, a sealant, cement, caulk or adhesive layer 35 may be applied to the lower surface 313 of the baseplate 316 to adhesively join and seal the baseplate 316 to the outer surface 52 of the wall sheathing or sub-structure 52 optionally covered by membrane 51, into which the shaft 316 is threadably received. In this situation, it is preferable to place the sealant layer 35 (or gasket not shown) beneath baseplate 316 prior to fully sealing anchor 310 in place. The anchor 310 is then tightened down with the baseplate 316 over the sealant (or gasket) 35 to seal it in place. When a rubber gasket having a central opening or the like, is utilized, the gasket 35 would be received around shaft 316 prior to screwing anchor 310 into the sub-structure. The gasket opening then would be received over shaft 316 with the gasket interposed between lower side 313 of baseplate 316 and the siding 50 or membrane 51.
Once the screw anchor 310 is secured to the frame structure 50, a bolt 85 is inserted through the internal bore 84 of hinge part 82 and is screwed into the threaded bore 326 of the long neck 322 and, in turn, into the intended threaded bore 317 of screw anchor 316. The hinge part 82 essentially becomes part of the long neck 322. After installation, the window shutter 80 via the central bore of hollow collar 84 of its hinge plate 87 is rotatably mounted on the upstanding pin 83 of hinge part 82 and is pivotably positioned onto the mounted hinge part 82. As can be seen, the shutter 80 is actually supported by two hinge plates 87 and collars 86 and two long neck screw anchors 310 each having a hinge part 82 and pin 83.
As can also be appreciated from the foregoing, materials of anchors, their specific dimensions, shape threading configuration and size, etc., depend on the application and the surrounding building material, such as metal, wood, concrete or some other composite. For most applications, the baseplate is preferably circular-shaped, although other regular or irregular shapes or non-planar configurations could be used for certain applications. Similarly, it is anticipated that the types of fasteners, screws or bolts, will also be chosen to be compatible with the supporting surfaces. Also, the elements of the various embodiments may be substituted for one another where appropriate. Furthermore, while the various parts of the anchor assemblies are preferably made of stainless steel, they could be made of other materials or metals, such as, for example, aluminum, bronze, or metal, carbon fiber or ceramic alloys, and plastic.
In use, the blind bore, of course, has a diameter that is less than the external diameter of the screw or bolt. For example, for a practical application the screw or bolt screw may have an external diameter of ½′ and the bore a diameter of ⅜′. However, as mentioned above, the dimensions of the diameter of the screw or bolt can vary, as well as the length of the bore, the long neck and the screw or bolt. For example, preferably, the shaft of lag screw has an external dimension which is ⅜″ or larger. However, both the dimensions of screw and the thread configuration thereof can vary depending upon the application, such as, e.g., the nature of the material, and purpose of the anchor and what it is used for, e.g., windows and doors, for which it will serve as an anchor and fastener.
Similarly, the length of the long or extended neck may be in any useful range and typically may be between approximately 0.10 inch and 2.5 inches, but preferably 1.0 inch. As mentioned above, the height or length of long neck is dimensioned to generally conform to the width of the sheathing or other structure from which it extends so as to provide a flush mount, or it may advantageously have a length that is shorter or longer than the width of the sheathing or other structure for other applications, if so desired.
It should be noted that, aside from the Allen key and screwdriver slot other means or other configured tool ports could instead be used to assist the user in screwing in and/or removing the anchor 110 to, or from, a building support. For example, the plug 133 or baseplate 111 could be configured to receive other known tools used for fastening and/or unfastening, such as Torx drive, Phillips head, or star bit tools which may utilize other shapes, e.g., pan head, round, oval, etc. for the tool port.
Accordingly, while particular embodiments of the invention have been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the prior art will allow and that the specification be read likewise. It will therefore be appreciated by those skilled in the art that other modifications could be made thereto without departing from the spirit and scope of the invention.
