The federal Occupational Safety and Health Administration (“OSHA”) recently rescinded a directive issued in 1999 that allowed for certain alternative means for employing fall protection on residential construction projects. The result of the rescission was to impose all of the fall protection requirements of Subpart M of 29 CFR 1926 on residential construction projects, making the requirements equal to those imposed on commercial construction projects.
Subpart M of the OSHA regulations stipulate that fall protection must be utilized for the safety of workers on a walking/working surface with an unprotected side or edge and which is six (6) feet or more above a lower level, including the ground. The fall protection can consist of a safety net system, personal fall arrest system or a guardrail system.
A wide variety of guardrail, safety net and fall arrest systems have been created and are available on the market, however virtually all of the existing available systems have critical deficiencies and shortcomings. With respect to guardrail systems, most commercially available systems must be secured to the actual work surface, and therefore must be removed in order to complete tasks on the edge of the work surface or above or below it, placing workers at risk.
In addition, available guardrail systems are anchored via nails, bolts or screws, requiring tools or power equipment to fasten the anchoring mechanism or component in an almost “permanent” attachment method. Such means and methods of attachment or anchoring require a substantial investment of time and material, and require a higher level of knowledge and an enhanced operator skill set, significantly reducing or precluding the transferability or portability of the system and the re-use of many components.
Further, most of the systems described are more complicated than necessary, which results in worker non-compliance in the placement or application of the system due to system ignorance, haste, or lack of proper tools or materials.
In addition to the new onus being placed upon residential builders and contractors, there is a need for a simplified, more efficient, more cost-effective portable fall-protection and guardrail system in the commercial and residential construction and safety industries.
The features and advantages of the various embodiments will become apparent from the following detailed description in which:
It should be noted that the height and depth of the structural member 130 illustrated in
In order to do any work on the next level some type of fall protection system is required. Railing systems are often used along exterior walls or openings in the floor of the interior (e.g., stair cases). Railing systems that are secured in some fashion to the next level (e.g., screwed into the flooring, secured to the joists or other structure of the next level) would require an individual to be on the next level to install the railing system. Accordingly, a separate fall protection system would be required to install the railing system. Furthermore, if the railing system is secured to the next level it may be in the way of the framing for the next level or possibly the flooring.
What is needed is a railing system that may be installed without the need for an individual to be on the next level for installation, does not interfere with work to be performed on the next level, can be installed without the need for special training/certifications and does not require any special tools. The railing system may include a mounting bracket that can be connected to a lower level (e.g., structural member). The mounting bracket may include an anchor point for mounting posts of a railing system or other systems. The anchor point may extend past where, for example, the framing of the upper level is to be installed so as not to get in the way. The anchor point may be such that the posts and rails of the railing system will be within a certain distance from the opening (e.g., exterior wall) as defined in the appropriate regulations.
It should be noted that the mounting bracket may be connected to any point in a project (e.g., building) that is strong enough to hold the bracket and any posts that are part of a railing system or any other system that may be mounted thereto. For ease of description the mounting bracket will be discussed as being connected to a structural member. The structural member is to be interpreted as any strong enough point as defined above and is not limited to load bearing structures.
The first bracket 300 and the second bracket 340 may be made of galvanized light gauge steel, aluminum or other formed metal(s), plastics, carbon fiber, composite materials, other materials providing sufficient strength and durability, or some combination thereof.
As illustrated in
According to one embodiment, rather than both the legs 320, 360 having holes and/or slots one of the legs may include posts that can pass through appropriate holes or slots in the other leg. The leg not having the posts may include one or more slots that may include one or more grooves extending from one or both sides. The posts may slide within the slot until the appropriate configuration is found and then the post may be slid off to the side into the grove to secure the legs together. As one skilled in the art would recognize, there are numerous ways for securing the legs and brackets together so as to provide an adjustable securing means.

It should be noted that the adjustable anchor point is not limited to the embodiments illustrated in
The mounting bracket 600 may include a first bracket 300 and a second bracket 340. The first bracket 300 may include a first leg 310 (illustrated as horizontal) and a second leg 320 (illustrated as vertical). The first leg 310 may rest on a first surface (e.g., upper) of the structural member and the second leg 320 may extend away from the structural member (e.g., upward) in alignment with a first edge (e.g., interior) of the structural member. The second leg 320 may include one or more holes 330 formed therein (two illustrated). The holes 330 may be to receive a connection means (not illustrated) in order to secure the first bracket 300 to the second bracket 340 in an appropriate configuration based on size of the structural member. One or more stanchions (two illustrated) 500, 510 may be secured to the end of the first leg 310. The receiving receptacles 500, 510 are illustrated as being square but are not limited thereto. Each of the receiving receptacles 500, 510 include a first open distal end (e.g., top) 610 and a second open distal end (e.g., bottom) 620 and a pathway 630 therethrough (illustrated as a double sided arrow traversing the receptacles 500,510) so that they may be capable of receiving posts (e.g., square posts). The posts may be used as part of a railing systems or as part of other systems, including but not limited to, signage, tools, hoists and platforms.
The receiving receptacles 500, 510 may include holes 520 formed therethrough that are alignable with holes in posts that it may receive. The posts may be secured at the appropriate configuration by passing a connection means (e.g., screws, pins, rods) through the aligned holes 520. The receiving receptacle 500, 510 utilized to secure a post for a railing system depends on the specifics of the job being performed (e.g., depth of the structural member). The post needs to be past where work is to be performed but within the limits defined in the appropriate specifications (e.g., 2 inches). The configuration of the post and the receiving receptacle 500, 510 also varies based on providing the toe kick and railing at the appropriate heights.
The first leg 310 may have a similar size and shape to the receiving receptacles 500, 510 to assist in securing them together. The receiving receptacles 500, 510 may be welded together and may also be welded to the first leg 310. The first leg 310 may be welded to the second leg 320.
The second bracket 340 may be an L-shaped bracket that includes a first leg 350 (illustrated as horizontal) and a second leg 360 (illustrated as vertical). The first leg 350 may be in contact with a second surface (e.g., lower) of the structural member and the second leg 360 may extend toward the structural member (e.g., upward) with a portion of it resting on the first edge (e.g., interior) of the structural member. The second leg 360 may include one or more holes 370 (four illustrated, 2 columns of two) formed therein. The holes 370 may be to receive a connection means 380 (e.g., a bolt, a rod, a screw) in order to secure the first bracket 300 to the second bracket 340 in an appropriate configuration based on size of the structural member.
The post 800 may include a plurality of brackets 820 (e.g., three illustrated) connected thereto. The brackets 820 may extend from the post in a direction oriented toward the bearing wall. The brackets 820 may be welded or otherwise permanently attached to the post 800. The brackets 820 may be, for example, “L” shaped where the top end is open to receive a rail or may be “U” shaped (as illustrated) where the brackets 820 are enclosed and the rail needs to be slid thereinto from the side. The rails may be made of wood, aluminum or other materials providing sufficient strength and durability. The rails may be, for example, conventional 2″×4″ or 2″×8″ railings, but the size is not limited thereto. The brackets 820 may include hole(s) 830 formed therein enabling a securing means (e.g., screw, nail) to secure the rail therein.
The posts have been illustrated and discussed with respect to railing systems but are not intended to be limited thereto. Rather, the posts could include varies items (e.g., connectors, hooks, platforms) connected thereto that enable the posts to be part of any number of systems. For example, the posts could include various hooks that enable a worker to secure their tools or the like thereto. The posts may include connectors that enable signs to be hung therefrom. The posts may include platforms that enable walkways to be formed between posts. As one skilled in the art would recognize, the mounting brackets 600 enables posts having different configurations to be connected thereto and thus enables various different systems to be created.
According to one embodiment, an anchor point may be desired past the first edge (e.g., internally) of the structural member as well as past the second edge (e.g., externally). The anchor point may be utilized to secure, for example, a frame for a walkway that could be utilized to perform operations on the lower level. The anchor point may be included on a second bracket of the mounting bracket. The anchor point may include a receiving receptacle connected to the second bracket.
The first bracket 1110 may include a plurality of plates (e.g., three illustrated) 1120, 113, 1140 and one or more (e.g., two illustrated) open-ended receiving stanchions 1150, 1160. The plates 1120, 113, 1140 and the receiving receptacles 1150, 1160 may be made of galvanized light gauge steel, formed metal, composite or other materials providing sufficient strength and durability. The second plate 1130 may be connected perpendicularly to the first plate 1120 (illustrated as being located at center line of the first plate 1120 but not limited thereto). The first and second plates 1120, 1130 may be welded or otherwise permanently attached. As illustrated, the first plate 1120 runs horizontally and may act as a base (first leg) and the second plate 1130 runs vertically and may act as a spine. The first and second plates 1120, 1130 may be aligned at a first end and the second plate 1130 may extend past the first plate 1120 at a second end. The first plate 1120 may include hole(s) 1122 formed therein on either side, or both sides, of the second plate (spine) 1130. The hole(s) 1122 may optionally receive a securing means (e.g., nail, screw, bolt, fastener) to anchor the top bracket 1110 to a structural member.
The third plate 1140 may be connected perpendicularly to the first end of the first and second plates 1120, 1130 (illustrated as lower edge connecting to first plate 1120 and center vertically connecting to second plate 1130). The plates 1120, 1130, 1140 may be welded or otherwise permanently attached to each other. The third plate 1140 may have dimensions equal to respective sides (e.g., short sides) of the first and second plates 1120, 1130 (illustrated as a square). The third plate 1140 (second leg) may include hole(s) 1142 formed therein on either side, or both sides, of the second plate (spine) 1130 (e.g., one hole illustrated on each side of the spine 1130). The hole(s) 1142 may receive a securing means (e.g., nail, screw, bolt, fastener) the purpose of which will be described in more detail later. According to one embodiment, the first plate 1120 and the third plate 1140 may be a single plate that is bent to create an angle (e.g., 90 degrees as illustrated).
The receiving receptacles 1150, 1160 are illustrated as being square, but are not limited thereto. The receiving receptacles 1150, 1160 may enable a post to pass therethrough and be secured therein. The receiving receptacles 1150, 1160 are located at the second end of the first and second plates 1120, 1130. The receiving receptacles 1150, 1160 are secured to the second plate 1130 at a location past the end of the first plate 1120 so the first plate 1120 does not interfere with a post passing therethrough. The receiving receptacles 1150, 1160 (e.g., lower edge as illustrated) may be secured to an edge of the second side of the first plate 1120 and extend upward therefrom.
As illustrated, a first receiving receptacle 1150 is mounted on a first side (far side as illustrated) of the second plate 1130 (spine) and a second receiving receptacle 1160 is mounted on a second side (close side as illustrated) of the second plate 1130. The second receiving receptacle 1160 may be mounted at the second end of the second plate 1130 (act as a rear/outer receiving receptacle) and the first receiving receptacle 1150 may be mounted a certain distance from the second end of the second plate 1130 (act as a forward/inner receiving receptacle). The second end of the first plate 1120 may be stepped so that a respective one of the receiving receptacles 1150, 1160 can be secured to a respective edge of the first plate 1120. For example, as illustrated a second side (close side) of first plate 1120 may extend further than a first side (far side) so as to connect to the second (rear/outer) receiving receptacle 1160 and the first (forward/inner) receiving receptacle 1150 respectively.
The receiving receptacles 1150, 1160 may include holes 1152, 1162 formed therein for the purpose of receiving a securing means (e.g., pins, bolts, rods) to secure a post (e.g., a post having one or more sets of aligned holes) therein at a defined height.
The second bracket 1170 may include two plates 1180, 1190. The fourth and fifth plates 1180, 1190 may be made of galvanized light gauge steel, formed metal, composite or other materials providing sufficient strength and durability. The fourth and the fifth plates 1180, 1190 (second and first legs of the second bracket 1170) may have the same width and may be perpendicularly connected to each at edges thereof so as to form an “L”. The plates 1180, 1190 may be welded or otherwise permanently attached to each other. The fourth plate 1180 may include a plurality of holes 1182 capable of being aligned with the hole(s) 1142 (2 rows of 2 holes illustrated). According to one embodiment, the fourth and fifth plates 1180, 1190 may be a single plate that is bent to create an angle (e.g., 90 degrees as illustrated).
The first bracket 1110 and the second bracket 1170 may be secured to one another in a non-permanent and adjustable manner such that the third plate 1140 and the fourth plate 1180 abut each other. The plates 1140, 1180 may be secured to each other by aligning the hole(s) 1142 with select hole(s) of the plurality of alignable holes 1182 and securing together with the connection means 1195. The connection means 1195 may be, for example, bolts, screws, or pins and nuts may also be utilized for additional securing. The plurality of alignable holes 1182 enables adjustment in the configuration of how the plates 1140, 1180 and the first bracket 1110 and the second bracket 1170 are secured together. The adjustment is to provide the ability to utilize the mounting bracket 1100 with, for example, different depths of structural members.
The mounting bracket 1100 may be installed such that the first plate 1120 of the first bracket 1110 is placed on a first (e.g., upper) surface of the structural member and the third plate extends away from (upward) the structural member in alignment with a first edge (e.g., interior) thereof. The receiving receptacles 1150, 1160 may extend past a second (e.g., exterior) edge of the structural member such that one of the receiving receptacles 1150, 1160 can be used to secure posts of a railing system. The fifth plate 1190 of the second bracket 1170 may be placed against a second (e.g., lower) surface of the structural member and the fourth plate 1180 may extend toward (upward) the structural member such that it rests on the first (interior) edge thereof. The second bracket 1170 and the first bracket 1110 are secured by aligning the hole(s) 1142 with select hole(s) of the plurality of alignable holes 1182 to account for depth of the structural member and securing together with the securing means 1195.
Although the invention has been illustrated by reference to specific embodiments, it will be apparent that the invention is not limited thereto as various changes and modifications may be made thereto without departing from the scope. Reference to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described therein is included in at least one embodiment. Thus, the appearances of the phrase “in one embodiment” or “in an embodiment” appearing in various places throughout the specification are not necessarily all referring to the same embodiment.
