Description

DOUBLE CLOSURE MOSQUETON HOOK Cross Reference to Related Requests This application claims the benefit of the Provisional Patent Application of E.U.A. No. 60 / 718,844, filed September 20, 2005, and Provisional Patent Application of E.U.A. DO NOT. 60 / 761,721, filed on January 24, 2006.
Field of the Invention The present invention relates to a double-locking carabiner hook for connecting a safety line, in relation to a load or a person.
Background of the Invention The double locking carabiner hooks are commonly used to connect a safety line in relation to a load or a person. Typically, the closed loop end is secured to the safety line and the hook end is secured to a support structure. When used in this manner, the attention in the safety line seats the hook end against the support structure and the inlet portion of the hook end is not required to carry the load in the safety line. However, sometimes users of carabiner hooks are inclined to wrap the safety line around the support structure and then connect the hook end to an intermediate portion of the safety line. This deviation from the recommended operating procedure can cause the safety line to bear against the entry portion of the hook portion and / or cause the carabiner hook inlet portion to be supported against the support structure. Under these circumstances, a fall arrest event can impart excessive force on the input portion resulting in the failure of the hook.

As shown in Figure 13, the first side 141 and the second side 149 curve outwardly from a close end to the third side 157. The first side 141 includes a first curve 147 and the second side 149 includes a second curve 155 that it forms a cavity 159, wherein the second end 188 of the coil spring 185 is positioned. The third side 157 provides a surface on which the coil spring 185 exerts pressure, since the helical portion 187 is compressed between the handle portion 112 within the groove 115 and the third side 157 and continuously deflects the third side 157 away from the handle portion 112. The coil spring 185 can be described as a means for biasing the actuator 140 toward a closed position relative to the handle portion 112. The projection 158 helps to maintain the coil spring 185 within the cavity 159. The coil spring 185 is preferably made of stainless steel spring cable having a diameter of 0.08128 cm. and a spring speed of about 70.6 to 86.3 kg / m. The external diameter of the spring 185 is preferably 0.9017 to 0.9271 cm., The height of the spring preferably being 0.8382 cm. at most. Activator 140 operates latch 160. Activator 140 is pivoted about rivet 193, latch 160 is pivoted about rivet 191, and bars 167 and 168 slide into slots 145 and 153. As shown in the Figures 7-11, the inlet 120 includes a third side 137 interconnecting a first side 121 and a second side 129. The first side 121 is generally rectangular and includes a projection 122 near the lower left corner with an opening 123 near the end of the projection 122. A projection 124 extends down near the bottom with an opening 125 near the right side of the first side 121. An inspection aperture 126 is near the upper right corner. As shown in Figures 7 and 9, the second side 129 is a mirror image of the first side 121. The second side 129 is generally rectangular and includes a protrusion 130 near the lower right corner with an opening 131 near the end of the second end. the projection 130. A projection 132 extends down near the bottom with an opening 133 near the left side of the second side 129 An inspection opening 134 is near the upper left corner The third side 137 interconnects the right side of the first side 121 and the left side of the second side 129 as shown in Figures 8, 10 and 11 A notch 138 in the upper part of the third side 137 receives the depressed portion 104 of the end 103 of the body 101 As shown in Figures 23-25 , a torsion spring 177 includes a first end 178 extending from a first loop 179 and a second end 180 extending from a second loop 181 A middle portion 182 interconnects the first loop 179 and the second loop 181 The first end 178 and the second end 180 extend upwardly from the loops 179 and 181 preferably at less than a right angle from where the middle portion 182 interconnects the loops 179 and 181 The torsion spring 177 is preferably made of stainless steel spring cable with a diameter of 0 1016 cm The internal diameter of the ties 179 and 181 is 1 2192 cm The middle portion 182 is straddled at the shoulder 109, and the ties 179 and 181 correspond to the opening 111 on each side of the body 101 The ends 178 and 180 extend upwards near the rim 110 The openings 125 and 133 of the inlet 120 are aligned and correspond with the opening 111 of the body The ends 178 and 180 extend upwardly between the sides 121 and 129 of the inlet 120 and continuously deflect the third side 137 away from the handle portion 112. The torsion spring 177 can be described as a means for deflecting the inlet 120. to a closed position relative to the hook portion 102. A rivet 190 extends through the openings 125, 111 and 133 and the ties 179 and 181 to secure the inlet 120 and the torsion spring 177 to the body 101. A thumb pad 172 as shown in Figures 21 and 22, generally D-shaped includes a grooved surface 174 over the curved portion of the thumb pad 172. An opening 173 extends through the center of the "D". The thumb pad 172 is positioned between the projections 122 and 130, with the grooved surface 174 exposed near the end of the projections 122 and 130, and the opening 173 corresponds to the openings 123 and 131. A rivet 192 secures the pad thumb 172 at the inlet 120 near the external surface of the body 101. In operation, the double-locking carabiner hook 100 is continuously deflected by the springs 177 and 185 to remain in the closed position, as shown in Figures 1 and 3. To open the double-locking carabiner hook 100, the coil spring 185 is compressed by pulling the third side 157 of the activator 140 towards the handle portion 112 and the activator 140 is pivoted back toward the handle portion 112 around the rivet 193, as shown in Figure 30. This is preferably done by compressing the third side 157 of the activator 140 against the handle portion 112. The closure 160 is actuated by the activator 140. closure 160 is pivoted down from a closed position to an open position around the rivet 191 through the interaction of the slots 145 and 153 of the activator 140 and the bars 167 and 168 of the closure 160. As the activator 140 is pivots, the slots 145 and 153 push the sides of the bars 167 and 168, while guiding the 167 and 168 from the front backwards of the slots 145 and 153, thereby causing the lock 160 to pivot down the end 103 towards the projection 109. This is shown in Figure 30. When the closure 160 is in the closed, locked position, the activator 140 and the closure 160 interfere with the opening of the inlet 120. In the closed, locked position, one end of the closure 160 is pivotally connected to the hook portion 102 and the opposite end of the closure 160 deviates to extend near the end 103 and the upper part of the inlet 120. The closure 160 extends in the general direction in which and the inlet 120 is compressed to pivot the inlet 120 to open the inlet 105. When a force is exerted against the inlet 120, the third side 137 of the inlet 120 makes contact with the opposite end of the closure 160, and the closure 160 prevents that the inlet 120 is pivoted inwardly toward the hook portion 102. Not only the closure 160 prevents the inlet 120 from pivoting to open the opening 105, but also the closure 160 acts as a compression member between the body 101 and the inlet 120 to reinforce and strengthen the inlet 120. The inlet 120 can then be pivoted about the rivet 190 by pulling the thumb pad 172 downward, preferably using the thumb of a person, which opens the inlet 120 and allows the access to the openings 105 and 116. This is shown in Figures 28 and 29. When the hook portion 102 engages an object, the inlet 120 is then released, and the torsion spring 177 makes that entry 120 closes. The inlet is closed when the notch 138 slides around the depressed portion 104 to close the openings 105 and 116. The activator 140 can be released at any time after the 120 inlet is opened, since open input 120 will keep trigger 140 in an open position. Once the inlet 120 has been released and is diverted to the closed position, the coil spring 185 will deflect the trigger 140 to the closed position. The closure 160 will swing to the closed position as the activator 140 is biased towards the closed position, and the closure 160 reinforces the inlet 120 in the closed position. The reinforced inlet 120 is capable of withstanding a stress load of up to at least 1634.4 kg. The dispersion openings 126 and 134 are optional and are used to determine whether the hook 160 is correctly positioned. When properly closed, no light can be seen through the inspection openings 126 and 134, since the closure 160 is in alignment with the inspection openings 126 and 134. If the closure 160 is not positioned correctly, and not is properly closed, the closure 160 does not align with the inspection openings 126 and 134 and allows light to be seen therethrough. The double-locking carabiner hook 200 generally includes a body 201, an inlet 220, an actuator 240 and a closure 260. The body 201 is preferably an integral component that includes a hook portion 202 and a handle portion 212. As shown in FIG. shown in Figures 35-40, the hook portion 202 extends upwardly from the handle portion 212 forming a tumbled J-shaped hook terminating at one end 203 and defining an opening 205 between the base of the hook portion 202 and the end 203. The end 203 includes a depressed portion 204 on each side of the hook portion 202 near the opening 205.

The torsion spring 277 may be described as a means for diverting the inlet 220 towards a closed position relative to the hook portion 202. A rivet (not shown) extends through the openings 225, 211 and 233 and the loops 279 and 281 to secure the inlet 220 and the torsion spring 277 to the body 201. In operation, the double-locking carabiner hook 200 is continuously deflected by the springs 277 and 285 to be in the closed position, as shown in Figures 31 and 32. To attach the carabiner hook to e double closure 200 in an unlocked position, as shown in Figures 33 and 34, the bottom portions 246 and 254 of the trigger 240 are compressed inward toward the handle portion 212, the coil spring 285 is compressed, the trigger 240 is pivoted about the rivet extending through the openings 245, 208 and 253, and the upper portions 242 and 250 are pivoted outwardly. The tips 263 and 267 slide within the slots 243 and 251, respectively, which causes the closure 260 to pivot about the rivet extending through the openings 264, 207 and 267 in a downward direction. The closure 260 is actuated by the actuator 240. The closure 260 is pivoted downwardly from a closed position., locked to an unlocked position, open around the rivet by the interaction of the slots 243 and 251 of the trigger 240 and the tips 263 and 267 of the closure 260. Then the trigger 240 is pivoted and the slots 243 and 251 guide the tips 263 and 267 thus causing the closure 260 to pivot downwards. When the closure 260 is pivoted down away from the tab 239, the inlet 220 is no longer closed by the closure 260. Preferably, the surface of the closure 260 near the tongue 239 is rounded to pivot the clear between the closure 260 and the inlet 220 to help pivot the closure 260.

Preferably, there is a space between the upper portion of the depressed portion 204 and the inlet 220 to provide a clearance between the upper portion of the depressed portion and the inlet 220 to assist in pivoting the inlet 220. When the Hook portion 202 engages an object, the inlet 220 is then released, and the torsion spring 277 causes the inlet 220 to close. The inlet 220 closes when the notch 238 slides about the depressed portion 204 to close the opening 205. The trigger 240 can be released at any time after the inlet 220 opens since the inlet 220 will keep the actuator 240 in an open position Once the inlet 220 has been released and is diverted to the closed position, the coil spring 285 will deflect the actuator 240 to the closed position. The closure 260 will swing to the closed position as the activator 240 is biased to the closed position, and the closure 260 reinforces the inlet 220 in the closed position. The reinforced inlet 220 is capable of withstanding a stress load of up to 1634.4 kg. The double-locking carabiner hook 300 is similarly constructed to the double-locking carabiner hook 200, but the double-locking carabiner hook 300 provides an alternate activator and an alternate closure for those of the double-locking carabiner hook 200. As shown in FIG. shown in Figure 64, the double-locking carabiner hook 300 includes a body 301 with a hook portion 302, an inlet 320, an activator 340 and a closure 360. As shown in Figure 65, the activator 340 is similarly built to activator 240, but the upper portions are different. Rather, they include oval-shaped openings near the ends, the upper portions 342 and 350 include notches 343 and 351, respectively, that open toward the ends of the upper portions 342 and 350. As shown in Figure 66, the 360 closure is constructed similarly to closure 260, but the tips are different. Rather it includes cylindrical structures with oval shaped flanges, tips 363 and 367 include only cylindrical extensions. Tips 363 and 367 are preferably well embossed as is well known in the art. The trigger 340 and the closure 360 assist in easier assembly of the double-locking carabiner hook 300 since the tips 363 and 367 can simply slide into place within the notches 343 and 351 Preferably, as shown in Figure 64 , there is added traction to the projection 324 of the inlet 320 to prevent cracking of the inlet 320 during manufacture It is recognized that the components of the double closing carabiner hooks 100, 200 and 300 can be exchanged between the modes The above specification, examples and data provide a complete description of the manufacture and use of the composition Since many embodiments of the invention can be made without departing of the spirit and scope thereof, the invention resides in the appended claims
