LOCKING SNAP-HOOK FOR USE WITH LINKLESS ATTACHMENT
1. A linkless snap-hook, comprising:
- a body member comprising a proximal hook, defining a proximal opening facing a first direction, and a distal hook, defining a distal opening facing a second direction;
a keeper depressible to and pivotally attached to the body member and movable between a first and second terminal positions with respect to the body member;
a first biasing means adapted to bias the keeper against pivotal movement with respect to the body member;
a locking grip member pivotally attached to the body member and depressible with respect thereto;
a second biasing means adapted to bias the keeper against pivotal movement with respect to the body member.
A linkless, locking snap-hook, comprising a body member with a proximal hook, defining a proximal opening facing a first direction, and a distal hook, defining a distal opening facing a second direction. A linkless, locking snap-hook also comprising a locking mechanism which has a keeper, a biasing means, and a locking grip member. The linkless, locking snap-hook is capable of accepting a variety of attachment devices.

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/750,499 filed on Oct. 25, 2018, entitled Linkless Attachment Arrangement for a Locking Snap-Hook or the like which is incorporated herein by reference in their respective entireties.
The present invention pertains to snap-hooks or similar apparatus used for securing and suspending workers and, more particularly, to a linkless apparatus for use therewith allowing direct connection of different attachment mechanisms without need of an intermediate attachment link.
Conventional locking snap-hooks and similar devices are well known and are used in myriad service industries. Such devices are widely used by workers in at least the electric utility, arborist, and construction industries.
Most snap-hooks or similar devices in use today feature locking mechanisms. Locking apparatuses have innumerable design variations. Each design, however, has as its main objective providing a snap-hook that is easily snapped into place, but which will not prematurely or unintentionally release. Although most snap-hooks work reasonably well, some hook mechanisms work better than others.
Further, snap-hook devices currently in use have an eye loop at an end of a body member for threading through and attaching various devices, ropes, or webbings. Other snap-hook devices have the eye loop positioned on the distal end of the device body and facing a first direction, and an open loop portion positioned on the proximal end of the device body and facing the same first direction. See, e.g., U.S. Pat. No. 9,382,939 at FIGS. 3-4. Such a design may not provide a device with sufficient desired/optimal strength for certain particular uses, or allow for attachment of a desired/optimal number of accessories and provide for a sufficient range of movement with attached accessories.
Description of the Related Art Section Disclaimer: To the extent that specific patents/publications/products are discussed above in this Background Section or elsewhere in this Application, these discussions should not be taken as an admission that the discussed patents/publications/products are prior art for patent law purposes. For example, some or all of the discussed patents/publications/products may not be sufficiently early in time, may not reflect subject matter developed early enough in time and/or may not be sufficiently enabling so as to amount to prior art for patent law purposes. To the extent that specific patents/publications/products are discussed above in this Background Section and/or throughout the application, the descriptions/disclosures of which are all hereby incorporated by reference into this document in their respective entirety(ies).
It is therefore a principal object and advantage of the present invention to provide a snap-hook device that eliminates one or more of the problems/issues discussed above. Benefits of the improved snap-hook device design include 3,600 lbs. rated gate, and an improved eye shape and/or location (with respect to an open loop portion) to allow for attachment of more accessories and provide a better range of movement with attached accessories.
In particular, the present disclosure is directed to an improved snap-hook device, which can include a body member, an eye loop positioned on a distal end of the body member and facing a first direction, and an open loop portion positioned on the proximal end of the body member and facing a second direction. The snap-hook device can also include a locking mechanism, which can function similarly in some ways as shown and described in U.S. Pat. No. 9,382,939, although can have some different configurations and functional effects in view of the improved “opposing direction” loop design described and illustrated herein (as should be understood and appreciated by a person of ordinary skill in the art in conjunction with a review of this disclosure).
The embodied invention will be more fully understood and appreciated by reading the following detailed description in conjunction with the accompanying drawings, in which:
Where applicable, like reference characters designate identical or corresponding components and units throughout the several views, which are not to scale unless otherwise indicated. Moreover, the embodiments disclosed herein may include elements that appear in one or more of the several views or in combinations of the several views.
The present snap-hook is a locking snap-hook for workers in service industries. The locking snap-hook apparatus has dual-actuated, simultaneously active release grips. It'"'"'s unique body member allows for selective attachment of different attachment devices without the need for an intermediate linking mechanism.

The opposing position of distal opening 20 and proximal opening 16 of body member 12 allows for attachment of more attachment devices and provides a better range of movement with attached attachment devices. Snap-hook 10 can be made to withstand immense pressure and weight without breaking to ensure the safety of users. Snap-hook 10 can also be made to comply with applicable safety standards. The material used to fabricate snap-hook 10 can be forged or stamped heat-treated metal such as but not limited to aluminum, titanium, and alloys.

When keeper 26 is in the first terminal position, such as in
Keeper 26 and locking grip member 28 are both depressible with respect to body member 12. Referring now to
A linkless attachment device 30 can be used in conjunction with snap-hook 10. The sigmoidal configuration of body member 12 and opposing distal and proximal openings 20, 16 allow for direct connection of different attachment devices 30 without the need of an intermediate attachment link. Proximal opening 16 is dimensioned and configured such that a variety of attachment devices 30 may be passed into proximal opening 16. Therefore, attachment devices 30 do not need to be formed as an integral portion of body member 12. Consequently, a separate casting or forging is not required for body member 12. This decreases expenses as separate tooling (e.g., molds, dies, etc.) and inventories is no longer required for each variation. Attachment devices 30 can be put into proximal opening 16 and then keeper 26 and locking grip member 28 can be permanently riveted in place.
