Description

Received at IPONZ on 23 December 2011 NEW ZEALAND PATENTS ACT, 1953 Divided out of New Zealand patent application 545672 dated 8 September 2004 COMPLETE SPECIFICATION ASSEMBLABLE JERK HANDLE FOR INFLATORS We, HALKEY-ROBERTS CORPORATION, of 11600-Ninth Street, North, St. Petersburg, Florida 33716, United States of America, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: 1 Received at IPONZ on 23 December 2011 - la - ASSEMBLABLE JERK HANDLE FOR INFLATORS Cross-Reference to Related Applications This application claims priority of corresponding provisional application 60/501,289, filed September 8, 2003, the disclosure of which is hereby incorporated by reference herein. This application is a divisional of NZ 545672.

BACKGROUND OF THE INVENTION Field of the Invention This invention relates to jerk handles for lanyards of manual inflators or the manual portion of automatic inflators.

Description of the Background Art As the term is commonly employed, a "jerk handle" is a handle connected to the trailing end of a lanyard composed of a cord. The standing end of the lanyard cord is then operatively connected to a device that requires manual actuation upon pulling of the jerk handle. A common application for jerk handles is in the inflation art. In the inflation art, a manual inflator (or the manual portion of an automatic inflator) is connected to an inflation valve of a cartridge of compressed gas. The assembly is then sealingly connected to an article to be inflated. Typical articles may include an inflatable life vest or life raft. To inflate, the user simply grasps the jerk handle and gives it a jerk to manually actuate the inflator causing inflation of the inflatable article.

Heretofore, the trailing end of a length of lanyard cord is molded in situ with the jerk handle to form the lanyard. U. S. Patent 5,099, 546, the disclosure of which is hereby incorporated by reference herein, discloses a mold-in-situ jerk handle for inflators. In this form, the lanyard is typically shipped to the manufacturer of the inflator who then assembles it by operatively coupling the standing end of the lanyard cord to the inflator in a manner dictated by the particular design of the inflator itself.

It is often desirous to have a supply of lanyards with different lengths of cords and therefore there exists a need in the industry for the ability for the inflator manufacturer to assemble the jerk handle to the trailing end of the cord as needed instead of having to purchase the assembly molded in situ. U. S. Patent 5,347, 685, the disclosure Received at IPONZ on 23 December 2011 of which is hereby incorporated by reference herein, discloses an assemblable jerk handle comprising a channel in which the lanyard cord is positioned and then secured by means of a strip with spikes that snap-fit into the channel to "spike" the lanyard cord and hold it in position. However, a more durable assemblable jerk handle is needed that more securely retains the lanyard cord and that is not disassemblable once assembled.

Therefore, it is an object of this invention to provide an improvement which overcomes the aforementioned inadequacies of the prior art devices and provides an improvement which is a significant contribution to the advancement of the inflation art, and/or to at least provide the public with a useful choice.

Another object of this invention is to provide a jerk handle that may be permanently affixed about the trailing end of a lanyard cord by a simple coupling of two components together to securely and permanently grasp the cord therebetween, and/or to at least provide the public with a useful choice.

The foregoing has outlined some of the pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.

Received at IPONZ on 23 December 2011 WO 2005/027359 PCT/US2004/029071 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in Figs. 1 and 2, the first embodiment of the jerk handle 10 of the invention comprises a base portion 12 with opposing handles 12A for easy grasping by a person's hand. Base portion 12 further comprises a neck portion 12B extending between the handle portions 12A.

As best shown in Fig. 2, the handle 10 further includes a cap 14 which is permanently snap-fitted to the base portion 12 by means of feet 14F that fit into corresponding slots in the neck 12B of the base portion, whereupon the cap 14 is then pivoted until four tabs 14T snap into similar slots formed in the handle portions 12A of the base portion 12. Alternatively, a living hinge may be employed in lieu of the two feet 14F.

Referring now to Figs. 3-7, the inside of the rear of the base portion 12 comprises a center channel 16 for receiving a lanyard cord 17. The channel 16 is flanked by opposing slanted teeth 18 of upstanding ridges 19. The teeth 18 are preferably configured in the manner disclosed in TJ.S. Patent 3,574,900, the disclosure of which is hereby incorporated by reference herein.

Toward the bottom of the channel 16, a circular upstanding protrusion 20 redirects the channel 16 about somewhat of a circular path 16C to exit the bottom 16B of the base portion 12. The teeth 18 coupled with the protrusion 20 form a circuitous path for receiving the lanyard Received at IPONZ on 23 December 2011 cord 17 such that the lanyard cod 17 is firmly grasped between the teeth 18. Indeed, preferably the distance between the opposing teeth 18 gradually decreases from the protrusion 20 to the uppermost end of the channel such that the lanyard cord 17 is progressively grasped tighter and tighter along the length of the channel 16.

As shown in Fig. 8, the lanyard cord 17 is forced into the channel 16 by means of the cap 14 having a longitudinal ridge 22 aligned with the channel 16 and dimensioned at a height to force the lanyard cord 17 to the bottommost portion of the channel 16 between the opposing teeth 18. Similarly, the inside of the cap 14 further includes an L-shaped ridge 24 of a configuration similar to that of the circuitous portion of the channel 16C such that the lanyard cord 17 is firmly forced therein when the cap 14 is assembled to the base portion. The cap 14 includes a protruding stay 21 with a V cut-out that forces the end of the cord 17 into a recess 21F. This assures that the cord 1 is firmly engaged by the teeth 18.

As shown in Figs. 9-16, a second embodiment of the jerk handle 110 of the invention comprises a base portion 112 with opposing handles 112A for easy gripping by a person's hand. Base portion 112 further comprises a neck portion 112B extending between the handle portions 112A.

The jerk handle 110 of the invention further includes a bifurcated plug 114 which is inserted into a center bore 116 formed within Received at IPONZ on 23 December 2011 the neck portion 112B. As best shown in Figs. 10 and 16, the center bore 116 preferably comprises a frastro cross-sectional configuration having a large diameter opening at its top and a smaller diameter opening at its bottom. Correspondingly, as best shown in Figs. 13 and 16, the bifurcated plug 114 preferably comprises a mating frastro configuration having an enlarged top and a reduced bottom for slidable fitting into the center channel 116. The frastro configurations of the center channel 116 and the bifurcated plug 114 assure that the bifurcated plug 114 is compressed inwardly as it is forced into the center bore 116 from the top to the bottom thereof.

In its preferred embodiment, the bifurcated plug 114 comprises a bifurcated configuration similar to that of a conventional hair pin with cooperating left and right side portions 114S having inwardly disposed teeth 118 that are preferably slanted toward the top and staggered relative to one another. The side portions are preferably connected together by a loop portion 114L that essentially serves as a living hinge to allow the side portions 114S to move inwardly as the bifurcated plug 114 is forced into the center bore 116.

As best shown in Figs. 11 and 12, the center bore 116 preferably comprises a roughly rectangular cross-sectional configuration having frustro lateral sides 120F that taper closer together from the top to the bottom of the bore 116 to slidably mate with the outermost surfaces of Received at IPONZ on 23 December 2011 the side portions 114S of the bifurcated plug 14 as the plug 114 is forced therein. Without departing from the spirit of this invention, the center bore 116 and the bifurcated plug 114 may alternatively comprise other tapei'ed configurations such as frustro-eonieal configurations.

As best shown in Pig. 16, during assembly, the trailing end of the lanyard cord 117 is positioned between the side portions 114S of the bifurcated plug 114 to be grasped by the inwardly protruding teeth 118 thereof. With the lanyard cord 117 being threaded through the center channel 116, the bifurcated plug 114 is then aligned therewith and forced inwardly. As noted above, as the bifurcated plug 114 is forced inwardly within the center channel 116, the frastro sides 114F of the plug 114 slide along the frastro lateral sides 120F of the slot 120 forming the center bore 116 whereupon the sides 114S progressively squeeze the lanyard cord 117 therebetween tighter and tighter. As shown in Fig. 16, the dimensions of the bifurcated plug 114 relative to the center channel 16 and the lanyard cord 117, are such that the bifurcated plug 114 will be recessed in position within the center bore 116 once the lanyard cord 117 is permanently grasped. In this manner, since the bifurcated plug 114 does not protrude from the top of the jerk handle 10, it is virtually impossible to remove and can be considered to be permanently installed.

The present disclosure includes that contained in the appended claims, as well as that of the foregoing description. Although Received at IPONZ on 23 December 2011 this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.

Now that the invention has been described, Received at IPONZ on 23 December 2011
