The invention relates to protective covers for vertical door hinges, and more particularly, to hinge covers which protect vehicles and other objects from potentially-damaging contact by a vertical door hinge.
Vertical doors, also known as overhead or garage doors, typically comprise an articulated door made up of an assembly of several joined-together panels or sections. Each panel is typically joined together one-above-the other by means of one or more hinge. The door is typically raised or lowered by means of a system of rollers and tracks. Rollers typically extend from outboard hinges on opposite ends of each panel. The rollers travel in tracks provided on opposite sides of the door. The tracks typically include a vertical section and a horizontal section which is typically at a 90° angle to the vertical section. A curved track section connects the vertical and horizontal sections. The hinges enable adjacent panels to pivot with respect to the other so that the panels can follow the tracks as the door is raised or lowered along the tracks.
Vertical doors can be raised or lowered manually or by means of an automatic door opener device. As is known, a typical automatic door opener includes an electric motor (e.g., ⅓ to ½ horsepower) which raises and, alternatively, lowers the vertical door by means of a chain or belt drive acting on a link attached to the vertical door.
A problem with existing vertical doors is that the hinges are almost always on the inside of the door and can contact and damage a vehicle parked in the garage as the door is raised or lowered. This can be a particular problem when using an automatic door opener because the user is typically spaced from the door and is unable to see whether the vehicle or other object is in too close of a proximity to the path of the hinge during door movement. Depending on the size and configuration of the hinges, the hinges can project away, or inward, from the inside surface of the panels anywhere from about 0.075 inch to 3 or more inches. And, vertical door hinges are robust and are frequently made of sturdy 11 to 18 gauge galvanized steel so they have the potential to damage anything in their path.
Should a vehicle be parked within a garage or other space in a proximity too close to the vertical door, it is possible that the bumper of the vehicle or another vehicle surface, could be in the path of the hinges extending out from the panels. Any contact between the robust hinge and the vehicle as the door is raised or lowered could scrape, gouge, or otherwise severely damage the vehicle. Damage could also occur to the vehicle should a moving vehicle strike a stationary hinge of a non-moving door.
Efforts have been made to solve the foregoing problems associated with damage that can be caused by vertical door hinges as described, for example, in U.S. Pat. No. 7,187,197 (Verhey, Sr.) and U.S. Pat. No. 9,708,841 (Kar). However, the hinge covers proposed in those documents have certain important disadvantages. The Verhey cover disadvantageously requires a labor-intensive installation process requiring disassembly of the door hinges from the door which many consumers may not wish to do, or be capable of doing. The Kar hinge cover has attachment structure which is difficult and uneconomical to manufacture and limits the protective capability of the cover. It would be an advance in the art to provide a hinge cover which would protect a vehicle or other object from contact with, and damage by, a vertical door hinge, which would be easy and simple to attach to the hinge, which would attach reliably to the hinge, and which would be easy and simple to manufacture.
Hinge covers which are removably attachable to a hinge for a vertical door are described herein. Hinges which may be covered by hinge covers of the types described herein may include leaves connected together by an axial barrel. The barrel may have a length dimension with opposite ends defining openings.
In embodiments, a hinge cover may have a generally wedge-shaped body and an axial connector removably insertable in a respective barrel end opening. Insertion of the axial connector may removably attach the hinge cover to the hinge.
The wedge-shaped body may include a downwardly-sloping ramp and may have a pair of opposed sidewalls. The ramp may slope downwardly from an upper end of the hinge cover toward a lower end of the hinge cover. In embodiments, the ramp may have a smooth outer surface. The sidewalls may extend in the same direction away from the ramp. The sidewalls may have opposed inner surfaces spaced from one another sufficiently to receive the barrel therebetween. The inner surfaces of the sidewalls may be proximate a respective end of the barrel.
In embodiments, the body of the hinge cover may comprise a unitary element of polymeric material. The sidewalls of such body may be flexible. The axial connector may comprise a pair of inwardly-facing coaxial tabs in the body. A tab of the axial connector may be on each of the opposed inner sidewall surfaces extending away from the respective sidewall inner surface. In such embodiments, the sidewalls may be flexed outward to enable insertion of the tabs in a respective barrel end opening to attach the hinge cover to the hinge. Each sidewall of the hinge cover may be spaced from the other sufficiently to fit over the opposite ends of the barrel which facilitates insertion of a tab into a respective barrel end opening.
In certain embodiments, each sidewall may have an outer edge and the edge may include a curvature or radius which is substantially identical for each sidewall. The curvature or radius of the edges enables the hinge cover to rotate upward about the coaxial tabs during glancing contact with a vehicle or other object to minimize possible damage.
By way of non-limiting example, the polymeric material used to manufacture hinge covers suitable for applications of the types described herein may have a memory which allows the hinge cover to flex and return to its original configuration. A non-limiting finished-form embodiment of a hinge cover useful for certain applications may have a durometer of about 40 to about 80 on the Shore A scale while other embodiments may have a durometer of about 60 to about 70 on the Shore A scale.
Other aspects and examples of the hinge cover and invention are described in the disclosure which follows.
Exemplary hinge covers may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which like reference numerals identify like elements throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. The drawings depict only embodiments of the invention and are not therefore to be considered as limiting the scope of the invention. In the accompanying drawings:
Referring to
An example of a hinge 11 used to join panels 15, 16, 17 of a vertical door 13 and capable of being covered with a hinge cover 10 will now be described in connection with
Leaves 21, 23 may include fasteners 47, 49, 50, 51, 53, 54 (e.g., a lag bolt) inserted through corresponding openings (hidden beneath the fasteners) in leaves 21, 23 to secure hinge 11 to an inside surface 55 of adjacent panels 15, 17, 19 of vertical door 13.
Hinge 11 may be made of many different materials. Galvanized steel of 11 to 18 gauge thickness is a typical material used to manufacture a hinge 11 of the type used with vertical garage doors for commercial and residential use. By way of non-limiting example only, a standard single barrel 33 hinge 11 may have a length of about 7.25 inches, a width of about 3.0625 inches, and a height of about 3.125 inches. Such hinge 11 width may represent the length dimension 37 of barrel 33. As can be appreciated, the outer edge surfaces of gussets 25, 27, 29, 31 are stiff and these parts and other parts of hinge 11 have the potential to damage any object in their path. While hinge cover 10 is described in connection with covering a hinge 11 of the type described herein, it should be understood that a hinge cover 10 may be configured to releasably couple to many different types of hinges besides hinge 11.
Referring next to
In an embodiment, hinge cover 10 may include an axial connector 73 disposed along axis 75 to connect hinge cover 10 to hinge 11. Axial connector 73 may be removably insertable into and within barrel 33 through a respective end opening 43, 45 of barrel 33. Insertion of connector 73 into and within barrel 33 removably attaches hinge cover 10 to hinge 11 in the examples.
In embodiments, body 57 may be of a unitary type; in other words, body 57 may be a single part. Referring to
Body 57 may be provided with a lower end 77 and an upper end 79. Ramp 59 may slope downwardly from upper end 79 toward lower end 77 to provide body 57 with the generalized wedge shape illustrated in
Ramp 59 outer surface 81 is the part of hinge cover 10 expected to contact a vehicle 83 bumper 85 or other object. Preferably, outer surface 81 is generally smooth which is useful to minimize any structural or cosmetic damage to the vehicle 83. Further, smooth outer surface 81 may be of a non-marring material to further minimize or eliminate any potential for cosmetic or other damage to vehicle 83 bumper 85 or another object.
Referring next to
In the examples, each tab 87, 89 may extend inward and toward the other tab 87, 89. Tabs 87, 89 may be spaced apart from the other for the purpose of connecting hinge cover 10 to hinge 11 as described in more detail herein.
Referring to
Hinge cover 10 is constructed in such a way that energy from a moving vertical door 13 may be dissipated into hinge cover 10 rather than into vehicle 83 bumper 85 or another object contacted by hinge cover 10. Flexure of tabs 87, 89 and sidewalls 61, 63 are thought to produce this result so that vertical door 13 movement against a vehicle 83 bumper 85 or other object may be stopped, or so that hinge cover 10 may ride over the vehicle 83 bumper 85 or other object without causing damage.
In such examples, tabs 87, 89 may be sized to fit into and within barrel 33 openings 43, 45. Insertion of male tabs 87, 89 into and within barrel 33 provides for a more positive removable connection of hinge cover 10 to hinge 11 as compared to a cover which might clip over barrel 33 and which could allow hinge cover 10 to be more easily detached from hinge 11 during operation. Further, male-type tabs 87, 89 are easy and simple to manufacture as compared with other types of more complex attachment structure, such as a female connector designed to clip over barrel 33. And, male-type tabs 87, 89 can be easily removed from within barrel 33 simply by spreading sidewalls 61, 63. In this manner, hinge cover 10 may be removed from hinge 11, thereby providing for a hinge cover 10 which is removably attachable with respect to hinge 11.
Tabs 87, 89 may have a frustoconical shape as illustrated in
Body 57 may optionally include a pair of ports 93, 95. Ports 93, 95 may be entirely through body 57 and ramp 59 enabling a person to see tabs 87, 89 through body 57 to make it easier to fit tabs 87, 89 into openings 43, 45 at respective ends 39, 41 of barrel 33 during attachment of hinge cover 10 to hinge 11 and to see tabs 87, 89 removed from barrel 33 during detachment of hinge cover 10 from hinge 11.
Referring now to
Body 57 of hinge cover 10 may be made of one or more polymeric material. By way of non-limiting example, such polymeric material may yield a finished form hinge cover 10 having a durometer of about 40 to about 80 on the Shore A scale. A preferred durometer range of about 60 to about 70 on the Shore A scale may yield a body 57 with excellent flexibility yet minimal deformation properties so that hinge cover 10 will remain on hinge 11 during contact with a vehicle or other object and yet minimize force applied by the door which could damage the vehicle or other object.
By way of non-limiting examples, representative polymeric materials suitable for use in making a hinge cover 10 body 57 may include thermoplastic elastomers (TPE), flexible polyvinyl chloride (FPVC), and silicone rubber. Representative thermoplastic elastomers may include styrenic block copolymers, thermoplastic polyolefinelastomers, thermoplastic vulcanizates, thermoplastic polyurethanes, thermoplastic copolyesters, and thermoplastic polyamides.
Thermoplastic elastomers are sometimes referred to as thermoplastic rubbers. They are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. Thermoplastics are relatively easy to use in manufacturing, for example, by injection molding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. A benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to the original or near original shape (i.e., material memory). Thus, a body 57 of thermoplastic elastomers or like materials has a memory such that the body 57 may flex and yet retain its original shape as illustrated for example in
Use and operation of an example of a hinge cover 10 will now be described in connection with
In both operational examples, there is shown a vehicle 83 parked in a garage 101. Garage 101 may be any type of garage such as a residential or commercial garage. Garage 101 has an opening 103 which is opened and, alternatively, closed by a vertical door 13 (shown in cut-away view) consisting of articulated panels, three of which 15, 17, 19 are schematically illustrated in
A conventional automatic vertical door opener (not shown) may optionally be used to raise and, alternatively, lower vertical door 13. As described previously, an automatic vertical door opener may include an electric motor which raises and, alternatively, lowers the vertical door 13. As is known, conventional automatic vertical door openers typically include a current-overload sensor which stops and reverses the downward movement of the vertical door 13 should the vertical door 13 contact an obstruction before completing its full range of downward travel.

Referring next to the second operational example of
In
Referring next to
In this example, hinge cover 10 glancingly contacts bumper 85 and may rotate in the direction of arrow 109 about barrel axis 35 and tab 87, 89 axis 75. In this example, curved outer surfaces 69, 71 can roll against vertical door 13 allowing hinge cover 10 to rotate and ride over bumper 85. Such rotation further eliminates or minimizes any possibility of damage to bumper 85.
Referring finally to
A further advantage of hinge cover 10 is that it will protect against damage should the vertical door 13 and hinge 11 be in a non-moving fixed position. For example, if a person walking past vertical door 13 was to contact a non-moving hinge 11, hinge cover 10 would prevent injury to the person or tearing of the person's clothing. And, if a moving vehicle 83 was to contact a non-moving hinge 11 for some accidental reason, hinge cover 10 would protect vehicle 83 from unwanted damage by hinge 11.
