Abstract
Interlocking hook assemblies for elastic straps include an elastic member 500 including a pair of similar interlocking hook devices 100 connected to each end of elastic member 501. Each interlocking hook device 100, is provided with a connector 300 which is fixedly attached thereon. Each hook device can be connected, preferably in a locking manner, onto the other hook device creating a closed hook assembly thereby disabling the hooks to prevent entanglement of elastic or rigid straps when not in use or during storage and/or transportation. Multiple elastic straps 500 can be connected end-to-end forming an elongated elastic strap of desired length having closed central hooks with open hooks on each end. Interlocking hook assemblies for elastic members include an elastic member with interlocking hook devices 900 including two similar interlocking hook devices 800 with a connector groove 801 and a catch feature 802 and elastic member 811. Each interlocking hook device 800 is provided with a groove 801 and catch feature 802 designed to allow each hook to engage the other within their respective grooves and to releasably lock them together. Each hook device can be engaged and preferably locked onto the other hook device thereby disabling the hooks to prevent entanglement of the elastic member when not in use or during storage and/or transportation. Multiple elastic members 900 can be connected end-to-end forming an elongated elastic strap of desired length having closed central hooks with open hooks on each end.

DETAILED DESCRIPTION OF THE INVENTION
(34) Interlocking hook device 100 includes hook 101 with connector 300, with catch feature 304 which provide the ability for two similar hook devices 100 to assemble and lock onto one another thereby forming a closed hook assembly thereby disabling the hooks 101 and providing for tangle-free transportation and storage when not in use. Interlocking hook devices 100 can be connected and locked to interlocking hook device 200 (see
(35) As seen in
(36) Each hook 101 locks into the connector 300 of the other hook device 100, preferably frictionally (though they could, for example, magnetically lock). Each hook 101 preferably frictionally engages the connector 300 of the other hook device 100 (as withcatch feature 304).
(37) Elastic member 701 (
(38) Interlocking hook device 600 (see
(39) Interlocking hook device 800 (see
(40) Interlocking hooks devices 100 and 200 with strap 401 can be assembled by the following method:
(41) First: Assembly of interlocking hook device 100.
(42) Hook assembly 100 begins with the forming of connector 300 which begins as a section of round tubing having a tab section made from slits which are cut through the tubing wall and bent inward to create a catch feature 304. Connector 300 with catch feature 304 is installed onto the hook 101 and located on the straight shank section 103 of hook 101. The tubing is then crimped to form the final shape, generally in the form of a
(43) Second: Assembly of interlocking hook 200.
(44) Hook assembly 200 is assembled in the same manner as hook assembly 100 except that connector 300 is oriented on hook section 201 180 degrees relative to its position on hook assembly 100 (or approximately 180 degreesit is preferred that it be offset enough to allow two devices 100 and 200 to hook together with a frictional fit or some other fit which provides a releasable lock of devices 100 and 200 together). Preferably the force to release the lock is sufficient such that once locked together, hook device 100 or 200 remains locked to the other hook device 100 or 200 until a user deliberately unlocks them. Connector 300 can also be formed integral with hook devices 100 and/or 200 or a single piece of tubing can be spot welded onto hook sections 101 and 201 to form a connector. Connector 300 can also have a secondary spring clip inserted in hole 302, an insert which reduces the inner diameter of hole 302, a stamped protrusion into the inner diameter of hole 302, all of which will proved for a locking frictional engagement of hook device 100 upon hook device 200.
(45) Third: Assembly of elastic member assembly 400 with interlocking hook assemblies 100 and 200 (see
(46) First, elastic member 401 is assembled by installing straight section 106 of hook device 100 into hole 403 of elastic strap 401 and centering hole 403 in the center of bend section 105 of hook 100. Second, straight section 206 of hook device 200 is installed into hole 402 of elastic member 401 and then hole 402 is centered in the middle of bend section 205 of hook device 200.
(47) Fourth: Assembly of elastic member assembly 500 with interlocking hooks 100.
(48) First, elastic member 501 is assembled by installing straight section 106 of first hook 100 into hole 503 of elastic strap 501 and centering hole 503 in the center of bend section 105 of hook device 100. Second, straight section 106 of a second hook device 100 is installed into hole 502 of strap 501 and then hole 502 is centered in the middle of bend section 105 of second hook 100 device.
(49) Fifth: Construction of hook assembly 600.
(50) Hook assembly 600 can be constructed of a solid over-molded steel core over-molded with Polypropylene, Polycarbonate, Polyethylene or Nylon with inner steel core hook made from steel wire (high carbon spring wire (music wire ASTM A 228 or hard drawn ASTM A 227) formed in the shape of a hook device 600 including hole 602 and connector groove 601).
(51) Sixth: Assembly of elastic member assembly 700 with interlocking hook device 600.
(52) Elastic member 700 is assembled by installing hook device 600 onto each end of elastic cord 701 and fixedly attaching the ends of cord 601 into hole 602 of hook device 600.
(53) Seventh: Construction of hook assembly 800.
(54) Hook assembly 800 can be constructed of a solid over-molded steel core over-molded with Polypropylene, Polycarbonate, Polyethylene or Nylon with inner steel core hook 803 made from high carbon spring wire (music wire ASTM A 228 or hard drawn ASTM A 227) formed in the shape of a hook 808 including coil section 812 and having a connector groove 801 and a catch feature 802. Catch feature 802 consists of protrusions within the upper and lower portions of groove 801 wherein the protrusions have a span between each end which is shorter than the span across the mating section of hook 808. Catch feature 802 can also wrap around all or a portion of the upper and lower circumference of connector groove 801. Catch feature 802 can wrap around all or a portion of the upper or lower section of connector groove 801. Catch feature 802 can be constructed of a separate and flexible metal or plastic insert which can be fixedly attached to or within the engagement groove and which will have an opening with a smaller gap than the cross-sectional area of the mating hook section to provide for a locking engagement of one hook assembly 800 to another hook assembly 800. Two hook assemblies 800 can also be locked by means of a magnet embedded in hook body 810 at the center of the engagement groove wherein the magnet will provide a magnetic attraction to wire core 803 thereby preventing the release of one hook 800 from the other until the user applies sufficient force to overcome the magnetic attraction thereby releasing the hooks.
(55) Eighth: Assembly of elastic member 811 and interlocking hook assembly 800
(56) First, the coil sections 812 of a first and second steel hooks 803 are installed onto each end of elastic member 811 by means of screwing or pressing coil section 812 over elastic member 811 which has a slightly larger outer diameter than the inner diameter of coil section 812. An optional staple 813 having leg lengths approximately the same as the cross-sectional distance across the coil section 812 can be inserted over a section of the wire coil section 812 and through elastic member 811 (see
