[0016] In the following description, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various embodiments. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. Accordingly, the following detailed description is not to be taken in a limiting sense.

[0017] The present disclosure relates to a fall protection system having a base assembly, a height-adjustable mast assembly, a jib connected to a portion of the mast assembly, and a counterweight. The height-adjustable mast assembly includes a fixed mast section and a movable mast section that can be moved relative to the fixed mast section. Depending on requirements, the movable mast section can be locked to the fixed mast section. Furthermore, the mast assembly can be locked to the base assembly. The fall protection system can be used to stop or prevent falls of workers working at any worksite or manufacturing industry.

[0018] As used herein, the term "aligned" refers to angular alignment between a first component and a second component. If the first component is a protrusion or tab and the second component defines a complementary opening, groove, or slot, the first component can be at least partially received within the second component when the first and second components are aligned with one another. If the first and second components are offset from one another, the first component cannot be received within the second component. In some cases, the first and second components may be axially spaced from one another when they are aligned.

[0019] FIG. 1 illustrates an exemplary fall protection system 100. The fall protection system 100 may be used in industries such as construction, manufacturing, and maintenance. The fall protection system 100 may be transportable from one location to another depending on the requirements of the application. To this end, the fall protection system 100 may be received by a transport device 102. The transport device 102 may include a forklift, a hand truck, or any other transport device that may be used to facilitate transport of the fall protection system 100 from one location to another.

[0020] The fall protection system 100 includes a base plate 104 defining a first side 106 and a second side 108 defined opposite the first side 106. Further, a first surface 110 (shown in FIG. 2 ) is defined on the first side 106, and a second surface 112 is defined on the second side 108. The base plate 104 is generally rectangular in shape. Alternatively, the base plate 104 may be square in shape. Furthermore, the base plate 104 of the fall protection system 100 is receivable by the transport device 102. In one example, the base plate 104 may include one or more ports (not shown) for receiving the arms 114 of the transport device 102.

[0021] As shown in FIG. 2 , a base assembly 116 is connected to the base plate 104. Note that the base assembly 116 is pivotally connected to the base plate 104 such that the base assembly, mast assembly 128, and jib 152 of the fall protection system 100 can pivot relative to the base plate 104 as required. Thus, the base assembly 116 is pivotable about a pivot point 118 (shown in FIG. 3 ). Furthermore, the base assembly 116 is coupled proximate to the first side 106 of the base plate 104 using several mechanical fasteners 120 (shown in FIG. 3 ). More specifically, a plate 122 (shown in FIG. 3 ) of the base assembly 116 is removably coupled to the base plate 104. The mechanical fasteners 120 may include bolts, screws, etc. The mechanical fasteners 120 may be removed to facilitate pivoting of the base assembly 116 during tip-up installation or transportation. Additionally, a counterweight 126 is connected to the base plate 104 .

[0022] The fall protection system 100 includes a mast assembly 128 connected to the base plate 104 and disposed adjacent the first side 106 of the base plate 104. More specifically, the mast assembly 128 is connected to the base plate 104 by a base assembly 116. The mast assembly 128 is rotatable about a first axis "A1" defined by the mast assembly 128. The mast assembly 128 includes a fixed mast section 130 and a movable mast section 132. The movable mast section 132 is adapted to move relative to the fixed mast section 130 to adjust the height "H1" of the mast assembly 128. Thus, the movable mast section 132 can be moved relative to the fixed mast section 130 to enable variability in the height "H1" of the mast assembly 128 depending on application requirements. The movable mast section 132 can move along a first direction "D1" to increase the height "H1" of the mast assembly 128, and can move in a direction opposite the first direction "D1" to decrease the height "H1" of the mast assembly 128. In other words, the movable mast section 132 is telescopic relative to the base plate 104. Furthermore, in the stowed position of the fall protection system 100, the movable mast section 132 can be in a fully retracted position. When the fall protection system 100 is in use, the movable mast section 132 can extend relative to the base plate 104 based on relative movement between the movable mast section 132 and the fixed mast section 130. The fixed mast section 130 and the movable mast section 132 can include, but are not limited to, hollow square tubes.

[0023] Referring to FIG. 3 , a primary mechanism 134 is associated with the fall protection system 100. In one example, the primary mechanism 134 is embodied as a winch assembly. The primary mechanism 134 may hereinafter be interchangeably referred to as the winch assembly 134. The winch assembly 134 is operably connected to the movable mast section 132. More specifically, the winch assembly 134 is operably connected to the movable mast section 132 and moves the movable mast section 132 relative to the fixed mast section 130. The winch assembly 134 is further connected to the fixed mast section 130 via a bracket 142. The movable mast section 132 is movable based on operation of the winch assembly 134. The winch assembly 134 includes a cable 136. The winch assembly 134 is configured to at least one of move the movable mast section 132 relative to the fixed mast section 130 and lock the movable mast section 132 relative to the fixed mast section 130. The winch assembly 134 selectively applies a first tension force "T1" to the moveable mast section 132 to move the moveable mast section 132 relative to the fixed mast section 130 to raise the height "H1" of the mast assembly 130. Additionally, the winch assembly 134 selectively applies a second tension force "T2" to the moveable mast section 132 when the moveable mast section 132 is locked with the fixed mast section 130 to prevent relative movement between the fixed mast section 130 and the moveable mast section 132. The second tension force "T2" will hereinafter be referred to interchangeably as tension force "T2".

[0024] The winch assembly 134 further includes a cable 136 that selectively applies a tension force "T2" via the winch assembly 134. More specifically, the cable 136 is adapted to selectively apply a tension force "T2" to the moveable mast section 132 to prevent relative movement between the fixed mast section 130 and the moveable mast section 132. The cable 136 is also adapted to selectively allow relative movement between the fixed mast section 130 and the moveable mast section 132. More specifically, the cable 136 selectively applies a first tension force "T1" to move the moveable mast section 132 relative to the fixed mast section 130. The winch assembly 134 includes a first pulley (not shown) coupled to the fixed mast section 130 by a bracket 138, a second pulley 140, and a winch drum 150. The cable 136 is routed through the first pulley and the second pulley 140 such that one end of the cable 136 terminates at the upper end 146 of the fixed mast section 130. The winch assembly 134 may be operated manually or may be operated using a power drill (not shown).

[0025] The winch assembly 134 further includes a handle 148. To manually operate the winch assembly 134, an operator rotates the handle 148, which in turn rotates the winch drum 150 via a series of gears (not shown). Rotation of the winch drum 150 retracts or winds the cable 136 around the winch drum 150. Retraction of the cable 136 around the winch drum 150 raises the height "H1" of the mast assembly 128 by moving the moveable mast section 132 along a first direction "D1" (shown in FIG. 2). Furthermore, the winch assembly 134 applies a tension force "T2" to the moveable mast section 132 to hold it in a stationary position. More specifically, the winch assembly 134 locks the moveable mast section 132 with the fixed mast section 130 to prevent relative movement between the two sections. In one example, the winch assembly 134 may include a brake mechanism (not shown) that limits further winding of the cable 136 around the winch drum 150, thereby limiting relative movement between the moveable mast section 132 and the fixed mast section 130. Note that the moveable mast section 132 is held in a stationary position based on the second tension "T2" applied by the winch assembly 134. Furthermore, unwinding of the cable 136 causes the moveable mast section 132 to move in a direction opposite to the first direction "D1", thereby decreasing the height "H1" of the mast assembly 128.

[0026] When the winch assembly 134 is to be operated by a power drill, the handle 148 is replaced with a clutch adapter. The clutch adapter is coupled to the powered drive hub of the winch assembly 134. The power drill is then attached to the input shaft of the clutch adapter. When the power drill is operated, the input shaft rotates, which, through a series of gears, rotates the winch drum 150, retracting the cable 136 around the winch drum 150 and raising the height "H1" of the mast assembly 128.

[0027] As shown in FIG. 2 , the fall protection system 100 also includes a jib 152 that is inclined relative to and pivotally connected to the mast assembly 128. More specifically, the jib 152 is pivotally connected to the movable mast section 132. In the illustrated embodiment, the jib 152 is substantially perpendicular to the movable mast section 132. The jib 152 defines a first end 158 and a second end 159. A first bracket member 154 is fixedly connected to an upper portion 156 of the movable mast section 132. The first end 158 of the jib 152 is connected to the first bracket member 154 such that the jib 152 is pivotally connected at a pivot point 160. The first bracket member 154 may include a bearing and a shaft that facilitates pivoting of the jib 152 relative to the movable mast section 132. In some examples, the jib 152 may include, but is not limited to, one or more telescoping arms. Furthermore, when the fall protection system 100 is assembled, the jib 152 is held perpendicular to the mast assembly 128 by a bar 162. A first end 164 of the bar 162 is pivotally connected to the moveable mast section 132 by a second bracket member 166. A second end 168 of the bar 162 is connected to the jib 152 by a third bracket member 170.

[0028] In one example, the jib 152 includes an anchor point 172. As shown in FIG. 2 , the anchor point 172 is connected to the second end 159 of the jib 152. The anchor point 172 provides a point at which one end of a securing device, such as a cable, harness, or other such device, can be secured to the fall protection system 100. The other end of the securing device is secured to the worker, providing fall protection for the worker. In other examples, the location of the anchor point 172 may vary depending on requirements. For example, the jib 152 may include a track (not shown) fixed to the underside of the jib 152. To vary the location of the anchor point 172, a trolley (not shown) may be slidably or rotatably connected to the track, and the anchor point 172 may be connected to the trolley.

[0029] Referring to FIG. 4 , the fall protection system 100 includes a counterweight 126 connectable to the base plate 104 proximate the second side 108 of the base plate 104. In the illustrated embodiment, the counterweight 126 is generally cubic in shape. However, the shape of the counterweight 126 may vary depending on application requirements. The counterweight 126 is receivable within a slot 124 in the base plate 104. The base plate 104 defines the slot 124 on the second side 108. The slot 124 at least partially receives the counterweight 126 therein. The shape and size of the slot 124 are based on the shape and size of the counterweight 126. Furthermore, the material of the counterweight 126 includes at least one of a metal and a concrete. Thus, the counterweight 126 may embody a cast block of a metal or an alloy thereof. Alternatively, counterweight 126 may embody a cast block of concrete. In some cases, counterweight 126 may removably receive multiple weights. The number and type of weights may vary depending on the requirements of the application.

[0030] The counterweight 126 is removably connected to the base plate 104. Thus, the fall protection system 100 includes a plurality of fastening elements 174 for removably connecting the counterweight 126 to the base plate 104. The fall protection system 100 includes four fastening elements 174. However, the total number of fastening elements 174 may vary depending on requirements. Thus, the fall protection system 100 may include two fastening elements 174 for removably connecting the counterweight 126 to the base plate 104. A first end 176 of each fastening element 174 is connected to the base plate 104, while a second end 178 of each fastening element 174 is connected to the counterweight 126. The counterweight 126 includes a hook 180 that removably receives the second end 178 of the fastening element 174 for connecting the counterweight 126 to the base plate 104. The counterweight 126 shown herein includes four hooks 180 located on a side 182 of the counterweight 126. It should be noted that if the fall protection system 100 includes two fastening elements 174, the counterweight 126 may include two hooks 180 located on a side 182 of the counterweight 126.

[0031] More specifically, each of the sides 182 may include a single hook 180 for removably receiving the second end 178 of a corresponding fastening element 174 .

[0032] The plurality of fastening elements 174 includes at least one of a plurality of cables and a plurality of turnbuckles. In the illustrated embodiment, the fastening elements 174 are embodied as turnbuckles. Because the counterweight 126 is removably connected to the base plate 104, the counterweight 126 can be removed during transportation of the transport apparatus 102. Removing the counterweight 126 may allow the fall protection system 100 to be transported by a transport apparatus 102 with a smaller capacity by moving the counterweight 126 and the fall protection system 100 separately.

[0033] 4 and 5, the center of gravity "CG1" of the counterweight 126 is offset from the center 184 of the base plate 104. More specifically, the center of gravity "CG1" of the counterweight 126 is defined a distance "X1" (shown in FIG. 5) from the second surface 112 (see FIG. 5) of the base plate 104. In one example, the distance "X1" is within a range of approximately 1 foot to 2 feet, but is not limited to this. In a specific example, the center of gravity "CG1" of the counterweight 126 is within 2 feet (60.96 centimeters) of the front end of the transport device 102 (see FIG. 1) used to transport the fall protection system 100. Because the center of gravity "CG1" is within 2 feet of the transport device 102, the fall protection system 100 can be picked up and moved by a transport device 102 with a smaller capacity. More specifically, by connecting the counterweight 126 on the second side 108 of the base plate 104 so that the center of gravity "CG1" of the counterweight 126 is at a distance "X1" from the second surface 112, the center of gravity "CG1" can be shifted away from the tipping point, which in turn may enable the weight of the fall protection system 100 to be reduced while maintaining the overall size of the base plate 104.

[0034] 5 , in one example, a static equilibrium equation can be used to determine the weight of counterweight 126 required to support force “F.” Force “F” may include a horizontal component of force “F2” and / or a vertical component of force “F3,” which may be applied to fall protection system 100. The static equilibrium equation may use variables such as, for example, cantilever distance “X2,” anchor height “H2,” weight of fall protection system 100, center of gravity “CG2” of fall protection system 100, weight of counterweight 126, center of gravity “CG1” of counterweight 126, distance “X3” between fulcrum “F1” of fall protection system 100 and center of gravity “CG2,” distance “X4” between fulcrum “F1” and center of gravity “CG1” of counterweight 126, angle of load “L1,” and force “F” applied to fall protection system 100 at anchor point 172.

[0035] The position of the center of gravity "CG1" of the counterweight 126, which is a distance "X1" away from the second surface 112, may effectively counteract the force "F." This may allow for a reduction in the weight of the fall protection system 100, since the weight of the fall protection system 100 depends on the center of gravity "CG1." Thus, a reduction in the weight of the fall protection system 100 may allow for a reduction in the weight of the counterweight 126. Furthermore, reducing the weight of the fall protection system 100 may improve the transportability of the fall protection system 100, since the fall protection system 100 may be moved using a transport device with a smaller capacity. Therefore, customers of the fall protection system 100 may be able to use transport devices that are readily available.

[0036] It should be noted that the present disclosure may provide techniques for reducing the weight of the fall protection system 100 and allowing the center of gravity "CG1" of the counterweight 126 to be relocated away from the fulcrum "F1" while maintaining a suitably small footprint for the base plate 104. Such techniques may allow the weight of the counterweight 126 to be reduced, which in turn may allow the fall protection system 100 to be transported by a smaller carrier device and may also allow the cantilever distance "X2" to be further extended. Furthermore, the fall protection system 100 described herein may be easy to assemble and transport.

[0037] 6 illustrates a method 600 of assembling the fall protection system 100. The fall protection system 100 includes a base plate 104 defining a first side 106 and a second side 108 opposite the first side 106. Furthermore, the base plate 104 of the fall protection system 100 is received by the transport device 102. In step 602, a mast assembly 128 is connected to the base plate 104 adjacent to the first side 106 of the base plate 104. In step 604, a counterweight 126 is aligned with the second side 108 of the base plate 104. In step 606, the counterweight 126 is received adjacent to the second side 108 of the base plate 104.

[0038] At step 608, a counterweight 126 is removably connected to the base plate 104 proximate the second side 108 of the base plate 104. The counterweight 126 is removably connected to the base plate 104 by a plurality of fastening elements 174. The plurality of fastening elements 174 includes at least one of a plurality of cables and a plurality of turnbuckles. Further, the counterweight 126 is received within a slot 124 defined in the second side 108 of the base plate 104. Further, the counterweight 126 is connected to the base plate 104 such that a center of gravity "CG1" of the counterweight 126 is offset from a center 184 of the base plate 104.
