Manually operated snap hook

Abstract

A manually operated snap hook that includes a main body outer cylinder with an internal hook assembly and slide bolt assembly housed and sandwiched therein. The main body outer cylinder has a recessed portion that corresponds to recessed portions on the internal hook assembly and slide bolt assembly that has therein an actuator that is connected to a vertical spring, such that when the actuator is depressed, the slide bolt assembly allows for a bolt to move in the vertical direction along the main body outer cylinder such that it can both connect to and disconnect from the hook of the internal hook assembly, which emanates from the main body outer cylinder through a cut out. The internal hook assembly includes a male connecting member that extends beyond the bottom of the main body outer cylinder and connects to a female portion of a swivel ring assembly.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(28) Turning to the drawings, the preferred embodiment is illustrated and described by reference characters that denote similar elements throughout the several views of the instant invention.

(29) The preferred embodiment of the instant invention provides for a manually operated snap hook that eliminates the protrude actuating member of prior art snap hooks and replaces it with an indented concave area for actuation of the device to either open or close the closed loop of the snap hook.

(30) The device provides for a safe and more user-friendly way to engage the slide bolt, making the device ideal for easy and comfortable engagement with the user's fingers. The device utilizes a wide, concave shape on the slide bolt to reduce the pressure point exerted on the extremity of the user's finger tips. The spring load in pounds per square inch (PSI) is distributed over a wider area from prior art devices, thereby making usage easier and more comfortable.

(31) The device incorporates a cylinder-shaped body which is suitable for easy handling, durable by design and ideal for electronic engraving of a company logo, company name, or any other customizable image or word, such as an image or a name.

(32) The device primarily benefits those who may have difficulty with actuating common snap hooks. The concave slide bolt shape provides ease of use and improved comfort whether the user uses an index finger or a thumb. The cylindrical body is easy handle, durable and engravable as well providing an aluminum surface which can be anodized in a variety of colors or otherwise printed on all metallic materials per the desire of the user and/or manufacturer.

(33) It is contemplated that the materials used include, but are not limited to, aluminum, nickel, gunmetal, brass, zinc, plastic or composites. The size is scalable to however larger or small is desired.

(34) As seen in FIGS. 1-20 we see the various aspects of the preferred embodiment of the instant invention, which is a manually-operated snap hook 10 that includes a main body outer cylinder 12 with an internal hook assembly 28 housed therein along with a slide bolt assembly 44. Seen from the outside is the hook 14 that emerges out of the top of the main body outer cylinder 12 which has a cut out 26 to allow for the hook 14 to emerge therefrom. The hook 14 is connected to a bolt 16 which is a part of the larger internal slide bolt assembly 44 also housed inside of the main body outer cylinder 12.

(35) The main body outer cylinder 14 has a recessed portion 22 in alignment with the bolt 16 that includes an actuator 24 therein for depression of the snap hook 10 that allows the bolt 16 and the hook 14 to separate from each other. Beneath the actuator 24 in the same vertical direction is a spring 20 that allows for the movement of the bolt 16 when actuated. At the opposite end of the main body outer cylinder 12 from the hook 14 and bolt 16 is a swivel ring assembly 18. The swivel ring assembly 18 can be attached to a desired item or point while the actuator 24 can open and close the hook 14 by separating it from the bolt 16 through depression of the actuator 24 inside of the recessed space 22 of the main body outer cylinder 12.

(36) FIGS. 11-13 show the internal hook assembly 28 separated from the entire device to show the detailed parts, which include the aforementioned hook 14 that emanates out from the main body outer cylinder 12 which is attached to a main elongated portion 34 of the internal hook assembly 28, said main elongated portion 34 having a top 30 and a bottom 32 with flanges 38 extended out from the main elongated portion 34 at both the top 30 and the bottom 32 with a recessed portion 36 therebetween. The flanges 38 include apertures 40 through which the slide bolt assembly 44 is attached with the spring 20 placed under the slide bolt assembly 44 into the recessed portion 36 of the internal hook assembly 28. Below the bottom 32 of the internal hook assembly 28 is a male connector 42 that connects to the swivel ring assembly 18.

(37) The slide bolt assembly 44 is shown separated from the main device in FIGS. 14-16. The slide bolt assembly 44 has a top 58 and a bottom 60. Attached to the top 58 of the slide bolt assembly 44 is the aforementioned bolt 16 that emanates out the top open portion of the main body outer cylinder 12 for connection to and disconnection from the hook 14. The slide bolt assembly 44 has a main body elongated portion 46 and a recessed portion 48, both of which align with and correspond to the both the main body outer cylinder 14 and its recessed portion 22 and the internal hook assembly 28 and its main elongated portion 34 and recessed portion 36.

(38) The swivel ring assembly 18 is shown in various views in FIGS. 17-20. The swivel ring assembly 18 has a main base 54 with a top 52 through which is an aperture 50 that connects to the male connector 50 found on the internal hook assembly 28. A closed loop ring 56 connects to either side of the main base 54 of the swivel ring assembly 18. When connected to the male connector 50 of the internal hook assembly 28, the snap hook can rotate therearound.

(39) An alternate embodiment of the instant invention and its additional part are illustrated in FIGS. 22-26. In this embodiment, the snap hook 100 includes all of the same components as the preferred embodiment, including the main body outer cylinder 120, the hook 140 and associated assembly, the bolt 160 with modified slide bolt assembly 440, the swivel ring assembly, the spring and the recessed portion 22. What is added is an external actuator 220 which protrudes slightly out of the top of the recessed portion 22 of the main body outer cylinder 120 and is connected to the actuator 24 but provides a slight ledge upon which to exert pressure to move the bolt 160. FIGS. 24-25 shows the external actuator 220 in detail showing its top portion 240, its bottom portion 280 and the sloped face 260 that extends from the top portion 240 to the bottom portion 280 with the sloped face moving from one plane to another to provide a protruding ledge to depress to actuate the actuator 24. The back side of the external actuator 220 includes grooves 300 that fit into grooves 450 in the alternate embodiment of the slide bolt assembly 440 as shown in FIG. 26.

(40) The invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.

(41) The discussion included in this detailed description is intended to serve as a basic description. The reader should be aware that the specific discussion may not explicitly describe all embodiments possible and alternatives are implicit.
