DETAILED DESCRIPTION

(11) Referring now to FIGS. 1 and 4-6, the present skylight guard, generally designated 10, is shown. The guard 10 is well suited for placement around a skylight 12 on a flat roof 14. A skylight glass 16 is held in place by a surrounding frame 18, and offers a sturdy foundation about which the present guard 10 can be mounted. It is understood, however, while the preferred application for the present guard 10 is for protecting a skylight, the guard has equal applicability to openings in substrates other than skylights, such as those in floors or locations other than rooftops

(12) Included in the skylight frame 18 is a peripheral, or vertical surface 20 and an upper surface 22 which both are utilized in supporting the preferred embodiment of the present skylight guard. At least one but ideally multiple generally vertical legs 24 are placed along the frame, such that a lower end 26 of each leg contacts the peripheral surface 20 of the skylight frame 18 and an opposite, upper end 28 of each, generally vertical leg is elevated above that point of contact. When, as in one embodiment, the generally vertical legs 24 are perforated angle iron, two peripheral surfaces 20 at the corner of the skylight frame 18 are engaged by the leg. This contact enhances retention of the guard 10 on the skylight frame 18. Solid vertical legs 24 are also contemplated.

(13) Referring now to FIG. 4, perforations 30 in the angle iron legs 24 provide variable heights at which a third point of contact with the skylight frame 18 is attached. While alternatives are contemplated, a foot 34 is formed by a similarly perforated strip of metal that rests atop the upper surface 22 of the skylight frame 18. Perforations or slots 36 are aligned with those perforations 30 of an associated leg 24 and the desired leg-foot complex is created using fasteners 38, preferably nuts and bolts, each complementary pair connecting the foot 34 to one face of the angle iron leg. In both embodiments, which are not intended to comprise an exhaustive list of what has been considered, interior surfaces 40 of the leg 24 preferably engage the corresponding two surfaces 20 forming a corner of the skylight frame 18, and the foot 34 is mounted on the leg so it contacts or engages the upper surface 22 of the frame. It is also contemplated that the foot 34 is welded to the leg 24.

(14) Referring now to FIGS. 1, 5 and 6, moreover, the perforated legs 24 also provide attachment points for at least one, and preferably a plurality of horizontal members 42. In the preferred embodiment, a horizontal member 42 connects each pair of legs 24 and are arranged to create an enclosure 44, preferably a rectangle or square. However, other closed polygons, or other shapes of the enclosure 44 are contemplated. The horizontal members 42 have a first end 46 and an opposite second end 48, each of which has an eyelet 50 used to engage or attach the end to the selected perforations 30 in the leg 24. Fasteners 52, preferably threaded bolts and nuts or the like, are provided to secure the horizontal members 42 to the legs 24. Opposite the eyelet 50, each of the first and second ends 46, 48 has a slot 54. The horizontal member 42 is assembled by securing the opposing slots 54 in overlapping or aligned fashion and securing them using reclosable fasteners 56, preferably nuts and bolts or the like. The connection is secured by tightening the fasteners 56 when a desired length is achieved for the horizontal member 42.

(15) A middle portion 58 of each horizontal member 42 is located between the ends 46, 48 and is configured to be variably expanded (extended or retracted) along a generally horizontal axis by the operator upon installation on the skylight frame 18. The fasteners 54 are temporarily loosened during installation to enable the horizontal member 42 to be fit to the length of the frame 18. Once properly sized, the fasteners 54 are tightened. It is also contemplated that the horizontal members are slidably adjusted relative to each other, and are held in place using a clamp, preferably having a set screw or threaded tension member.

(16) Referring now to FIGS. 1-3 and 5 and 6, it is also contemplated that the horizontal members 42 have an upper end 60 and a lower end 62. In the preferred embodiment, the upper end 60 is provided with a laterally projecting lip 64. One or both of the first and second ends 46, 48 are provided with the lip 64, which when both ends have the lips, they overlap each other. Also, the lips 64 preferably extend in the same direction (FIG. 5).

(17) This laterally projecting lip 64 is used to support a cover 66, which itself can be any number of wooden boards or other materials, situated and extending over the skylight and its frame. A wooden cover 66 is shown in FIG. 2 as 66a, and a net cover 66 is shown in FIG. 3 as 66b. When the net cover 66b is employed, it is assembled on the lip 64 at sufficient tension for compliance with OSHA regulations. Suitable fasteners 68, such as screws, clamps, chemical adhesive or the like, well known in the art, secure the cover 66 to the lip 64. In an alternate embodiment, a net 66 is used as the skylight guard cover 66.

(18) Referring again to FIG. 1, it is contemplated that a supplemental support 72 is releasably, clampingly secured at each end to the upper end 60 of opposing upper horizontal members 42. The supplemental support 72, which is made up of a pair of overlapping, preferably L-shaped members like the horizontal members 42, is axially adjustable in length and is held in a desired position by at least one clamp 74. The clamp 74 is configured by manipulation by the user to hold the telescoping members in position, as by a thumbscrew or the like. In addition, the supplemental support 72 is secured to the horizontal members 42 using clamps 76, also releasably tightened by the user.

(19) Referring now to FIGS. 7-9, another embodiment of the present skylight guard is generally designated 100. Components shared with the embodiment 10 are designated with identical reference numbers. Important distinctions between the embodiments 10 and 100 include that the latter is secured by clamps to the skylight frame 18, the generally vertical leg 102 is axially adjustable and the horizontal members are slidingly engaged in the legs. More specifically, the vertical leg 102 is provided with a foot 104 having a shoulder or inner hook 106 that engages an underside of the skylight frame 18. An adjustable plate 108 engages or rests upon the upper surface 22 of the frame 18. Vertical adjustment of the plate 108 is achieved by use of a rotatable knob 110 that is connected to the plate by a threaded rod (not shown). The rod is threadably engaged in bulkhead or other support (not shown) in a foot housing 112 that is preferably hollow, and allows relative vertical sliding action of the plate 108 as the rod is rotated by the knob 110.

(20) The leg 102 is secured to the skylight frame 18 by hooking the shoulder 106 under the frame, then, using the knob 110, lowering the plate 108 until a snug fit is achieved relative to the upper surface 22. In this embodiment 100, the leg 102 also includes a vertically adjustable portion 114 that is slidable secured in a tube 116 attached to one side of the foot housing 112. A cotter pin 118 or the like slidably engaged in a throughbore 120 in the tube 116 engages a selected one of a plurality of vertically spaced mounting holes 122 in the vertically adjustable portion 114. Thus, the height of the vertically adjustable portion 114 is varied relative to the skylight 12.

(21) Another feature of the skylight guard 100 is that the vertical legs 102 slidably accommodate the horizontal members 124, which in the present embodiment are standard wooden beams sold at lumber yards, such as 24's 13's 23's or the like. The horizontal members 124 are slid into eyelets 126 which are secured to the vertically adjustable portions 114, as by welding, fasteners or other conventional technology. In the preferred embodiment, each vertically adjustable portion 114 has upper and lower eyelets 126a, 126b.

(22) Each eyelet 126 has a first component 128 extending in a first direction, and a second component 130 extending in a direction 90 displaced from the first component. Thus, the components 128, 130 appear V-shaped when viewed from above. This arrangement is provided for accommodating the horizontal members 124 that correspond respectively to the length and width of the skylight frame 18. It is contemplated that the angular orientation of the components 128, 130 to the vertically adjustable portion 114 may vary to suit the application.

(23) In use, the four vertical legs 102 are each secured to a respective area preferably a corner of the skylight frame 18. Then, the height of the vertically adjustable portions 114 are adjusted so that all are at the same height. Lastly, the horizontal members 124 are slidably inserted into the eyelets, to create a surrounding structure that protects the skylight 18 (see FIG. 7).

(24) Referring now to FIG. 10, an alternate embodiment of the present skylight cover 10 having modifications to the leg 24 and the foot 34 is shown fragmentarily and is generally designated 140. Components shared with the skylight guard 10 are designated with identical reference numbers. The skylight cover 140 incorporates the features of the cover 10, with only the foot 34 being modified. In the embodiment 140, a main distinguishing feature is that a foot 142 replaces the foot 34. In general, the foot 142 is configured for enveloping a corner 144 (designated in phantom) formed by the upper surface 22 of the skylight frame 18, as well as the peripheral vertical edge 20 of the frame.

(25) More specifically, each of the feet 142 includes a preferably integral L-shaped piece having a generally horizontal surface 148 and a generally vertical surface 150. One facet 148a, 150a of each surface is associated with a first skylight frame member, and a second facet 148b, 150b of each surface is associated with a second skylight frame member, the two frame members also forming the corner 144 of the frame 18. In one embodiment, the foot 142 is formed by welding, and is integrally secured to the leg by welding. However, the use of fasteners to secure the foot 142 to the leg is also contemplated, as is known in the art. In one embodiment, the foot 142 is formed from a length of 90-degree angle iron, which is then bent or formed to define a 90-degree angle.

(26) Thus, at each of the legs 24, the foot 142 engages the skylight frame 18 at four different locations, namely the corners 144, including two parts of the upper surface 22, one on each of the frame members, and two parts of the peripheral vertical edge 146, one on each of the frame members. The foot 142 rests upon the frame 18, without requiring supplemental fasteners. As such, once the cover 140 is placed upon the skylight frame 18, the enhanced contact area provided by the feet 142 enhances the retention of the cover on the skylight, especially during adverse weather, including high winds. At the same time, the cover 140 is still relatively simple to install on the skylight, as well as to remove once roof repairs are complete.

(27) While particular embodiments of the present adjustable skylight guard have been described herein, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
