Abstract
A support system for attaching safety railings, especially useful on construction sites. A clamp allows attachment to beams or posts of differing sizes, squeezing the beam or post using mechanical fasteners and, optionally, shims or spacers. A support arm is mounted on the clamp, and upright posts for safety wires or railings are removably mounted to the support arm.
Description
- This application claims one or more inventions which were disclosed in Provisional Application No. 61/480,135, filed Apr. 28, 2011, entitled “Safety Railing Clamp System”. The benefit under 35 USC §119(e) of the United States provisional application is hereby claimed, and the aforementioned application is hereby incorporated herein by reference.
- The invention pertains to the field of construction safety equipment. More particularly, the invention pertains to safety railings and apparatus for mounting such railings.
- The present invention is a support system for attaching safety railings, especially useful on construction sites. A clamp allows attachment to beams or posts of differing sizes, squeezing the beam or post using mechanical fasteners and, optionally, shims or spacers. A support arm is mounted on the clamp, and posts for railings that are removably mounted to the support arm.

FIG. 2 shows a detail of the clamp of the invention, within the box 2-2 ofFIG. 1 . -
FIG. 3 shows the invention mounted on an I-beam. -
FIG. 4 shows the invention mounted on a post. -
FIG. 5 shows an exploded view of the parts of a second embodiment of the invention. -
FIG. 6 shows a cut-through view of the second embodiment of the invention, along the lines 6-6 inFIG. 5 . -
FIG. 7 shows a cut-through view of the second embodiment of the invention, along the lines 7-7 inFIG. 5 . -
FIG. 1 shows a view of the safety railing support system of the invention. The system is used for attaching safety railings, especially useful on construction sites.FIG. 2 shows a detail of the clamp portion of the invention, from the portion ofFIG. 1 enclosed in dotted box 2-2.FIG. 3 shows the clamp portion of the invention in use on an I-beam. - The clamp is made up of a
clamp base 1 andfastening plates 2. Shims orspacers 3 are provided to keep the clamp aligned when it is in use. Slots orholes 5 in the base plate allow passage of mechanical fasteners such asbolts 22, which are threaded intoholes 7 in thefastening plates 2. Alternatively, theholes 5 in theclamp base 1 could be threaded, and theholes 7 in thefastening plates 2 could be made large enough to pass thebolts 22, in which case thebolts 22 would be tightened from the reverse side. Optionally, theholes 7 in the fastening plate and theholes 5 in the clamp base could both be made larger, and nuts (not shown) could be threaded onto thebolts 22.Holes 5 are preferably made as elongated slots, as shown in the figures, so as to allow the clamp to be used on different sized beams or posts. - A
support arm 4 is mounted on the clamp, preferably by having one end welded onto theclamp base 1. Thesupport arm 4 is preferably of square stock as shown in the figures, or could be made of I- or U-channel as desired. A number ofholes 9 allow attachment of anupright post 10 by passing afastener 14 throughholes 13 inflanges 11 andholes 9 in thesupport arm 4. Thefastener 14 could be a bolt as shown, secured in place withnut 15, or the holes in theother flange 11 could be threaded to accept the bolt. Alternatively, thefastener 14 could be a clevis pin or other suitable fastener, held in by a cotter pin or clip, or any other arrangement known to the art.Holes 12 in theupright post 10 allow passage of a safety wire (not shown) connecting a plurality ofupright posts 10 to form a safety railing. - As can be seen in
FIG. 3 , the invention can be used to attach thesupport arm 4 on theclamp base 1 to aflange 21 of an I-beam 20. Theclamp base 1 is placed against the outside of theflange 21, andfasteners 22 on each side of the beam are passed throughslots 5 and threaded intoholes 7 infastening plates 2 behind theflange 21. Shims orspacers 3 of approximately the same thickness as theflange 21 are put in place, theslots 6 in theshims 3 allowing theshims 3 to slip over thefasteners 22. Thefasteners 22 are slid inward in theslots 5 until theshims 3 are close to the edges of theflange 21, and then are tightened to clamp theflange 21 securely between theclamp base 1 and fasteningplates 2. -
FIG. 4 shows an alternative use, in which the invention is used to attachsupport arm 4 to asquare post 25. As with the I-beam flange 21 above, theclamp base 1 is placed against thepost 25, and the fasteners 23 (which need to be longer than thefasteners 21 for I-beams) are threaded intoholes 7 infastening plates 2 behind the post. Thefasteners 23 are slid inward in theslots 5 until they are close to the sides of thepost 25, and then are tightened to clamp thepost 25 securely between theclamp base 1 and fasteningplates 2. -
FIG. 5 shows a view of a second embodiment of the invention. The clamp system in this embodiment is the same as inFIGS. 1-4 , and will not be separately described here. - The embodiment of
FIGS. 5-7 differs from the first embodiment in several ways, each variation of which may be used independently or in combination with the embodiment ofFIGS. 1-4 . - First, as shown in
FIGS. 5 and 7 , this embodiment differs in how theupright post 10 fastens to thesupport arm 4. Specifically, instead ofbolt 14 passing throughholes 9 insupport arm 4 as in the first embodiment, in thisembodiment holes 13 inflanges 11 are placed lower down, such thatbolt 14 passes belowsupport arm 4.Upright post 10 can slide onsupport arm 4 as before, but instead of being limited to the locations ofpre-drilled holes 9, it can be fastened in place at any point along the arm by tighteningnut 15 andbolt 14, squeezingarm 4 betweenflanges 11. -
FIGS. 5 and 6 show an alternative method of fastening a safety wire 39 (not shown inFIG. 5 ) to theupright post 10. In this embodiment, theupright post 10 is formed with alongitudinal slot 30 running along one side of thepost 10—preferably, as shown here, the inner side closer to the clamp, although it could also be placed on the opposite side. The slot could simply be cut or otherwise formed up one side of a square orrectangular box post 10. Preferably, though, as shown inFIGS. 5 and 6 ,post 10 is extruded with a hollowrectangular portion 32 and a “T” shaped slot, having a side-to-side portion 31 andlongitudinal slot 30 running fromportion 31 to the outside of the extrusion. - A
fastener 36 having ahead 33 is placed with thehead 33 throughlongitudinal slot 30, the head extending into the side-to-side portion 31.Fastener 36 passes through a hole in awire grip plate 35, and anut 34 is threaded onto the fastener. While aflat plate 35 could be used, it is preferable to provide awire groove 38 into whichwire 39 can fit. When theplate 35 onfastener 36 is slid into the desired vertical position alongpost 10, andnut 34 is tightened ontofastener 36,wire 39 is gripped bywire grip plate 35 and held securely against thepost 10. - While only one
plate 35 andfastener 36 is shown inFIG. 5 , it will be understood that multiplewire grip plates 35 andfasteners 36 could be provided within the teachings of the invention, to provide for howevermany safety wires 39 are desired. - Finally, as seen in
FIG. 7 , the same form of extrusion shown for theupright post 10 inFIG. 6 can also be used for thesupport arm 4. The extrusion is extruded with a hollowrectangular portion 41 and a “T” shaped slot, having a side-to-side portion 42 andlongitudinal slot 43 running fromportion 42 to the outside of the extrusion along the length ofsupport arm 4. This allows awire support ring 46 to be threaded onto the end of afastener 45 which is slid intoslot 43. Thehead 44 of thefastener 45 fits in side-to-side portion 42, and once it is slid into the desired position alongsupport arm 4,nut 47 can be tightened to hold thefastener 45 in place inslot 43. - A safety wire (not shown) can then be threaded through
ring 46, andadditional rings 46 andfasteners 45 can also be provided, so that one or more safety wires can be provided along the length of thearm 4. Thesame ring 46 and fastener 45 arrangement could also be slid into theslot 30 onupright post 10 and fastened in place bynut 47, as an alternative to thewire grip plate 35 or in addition to one or morewire grip plates 35, or as a location to clip a safety rope, or any other reason where a ring would be desirable. - Accordingly, it is to be understood that the embodiments of the invention herein described are merely illustrative of the application of the principles of the invention. Reference herein to details of the illustrated embodiments is not intended to limit the scope of the claims, which themselves recite those features regarded as essential to the invention.
