Definitions

  • the present invention relates to the field of hook and loop fasteners and, more particularly, to a silent hook and loop fastener system that locks and unlocks a hook element to a loop element and wherein the hook element and the loop element can be separated from each other with little resistance and with little production of any audible sound, compared to standard hook and loop systems.
  • Hook and loop fasteners are known in the art and they have been used in many diverse applications.
  • the secure engagement of one half to the other and the substantial force required to separate the two halves has made these fasteners popular and useful.
  • the force that must be applied to achieve separation of the two halves can make the separation process difficult in some cases and can produce sound or noise which may be undesirable.
  • the inherently incremental nature of the known separation process requiring the two halves to be progressively "peeled" apart is generally responsible for the production of significant sound or noise. This sound or noise can make the use of hook and loop fasteners unsatisfactory in situations where silence is necessary such as in military combat situations or hunting activities.
  • Hook and loop fasteners designed for "heavy duty” applications with substantial holding force can require separation forces which may exceed the physical ability of certain users thereby further limiting the application of these types fastening devices.
  • Hook and loop fasteners are known which produce substantial holding force using electrical, magnetic, or thermal systems to lock and unlock hooks from loops. These systems are complex and relatively expensive and may not be practical in situations such as military combat or hunting activities.
  • This invention is a relatively silent fastener system having a hook portion and a loop portion wherein the hook portion has a base with hooks attached thereto.
  • curved hooks are inserted through a hook guide and guided into the loop portion, when the loop portion interfaces with the hook guide.
  • the base is laterally movable relative to the hook guide so that lateral movement of the base selectively moves the hooks into and out of the hook guide. This is accomplished by moving the base away from a first side of the hook guide towards a second opposite side of the hook guide so that tips of the hooks advance into the loop portion. The hooks become more curved in this configuration thereby locking the hooks into the loop portion.
  • the hooks can be further guided into the loop portion so that the hooks become more curved and the tips of the hooks advance further through the loop portion back into the hook guide.
  • the hooks are unlocked and removed from the loop portion by moving the base away from the second opposite side of the hook guide towards the first side of the hook guide so that the hooks are retracted out of the loop portion and into the hook guide with little production of any audible sound or noise.
  • the loop portion and the hook guide can, thus, be separated from each other with little resistance and with little production of any audible sound when the hooks are retracted out of the loop portion and back into the hook guide.
  • the hook guide is positioned adjacent to the loop portion and the base is moved laterally along the hook guide in a first direction to move tips of the hooks through the hook guide into the loop portion, thereby attaching the hook portion to the loop portion.
  • the base is moved laterally along the hook guide in the first direction to move the tips of the hooks back into the hook guide, thereby locking the hook portion to the loop portion.
  • the base is moved laterally along the hook guide in a second opposite direction to move the hook tips out of the hook guide, thereby unlocking the hook portion from said loop portion.
  • the base is moved laterally along the hook guide in a second opposite direction to move the hook tips out of the loop portion, thereby allowing separation of the hook portion from the loop portion without producing audible sound.
  • the hooks can have a linear configuration and are attached to a base at an angle of 20 degrees to 75 degrees relative to the base, and are angled from a first side of the base towards a second opposite side of the base. Lateral movement of the base selectively moves hooks into and out of a hook guide. The hooks are advanced into the loop portion at an angle, thereby locking the hooks into the loop portion. The hooks are unlocked from the loop portion by pulling them in reverse out of the loop portion at the same angle of insertion with little production of audible sound.
  • a hook guide is positioned adjacent to the loop portion and the base is moved laterally along the loop portion in a first direction to move tips of the hooks into the loop portion, thereby locking the hook portion to the loop portion.
  • the base is moved laterally along the loop portion in a second opposite direction to move the hook tips out of the loop portion, thereby unlocking the hook portion from the loop portion.
  • a hook guide can be attached to the loop portion wherein the hooks are inserted into the hook guide and can be extended from the hook guide into the loop portion.
  • a plurality of linear hooks are positioned at the ends of a stretchable hook base at an angle wherein the hooks are angled towards the center of the stretchable hook base.
  • the stretchable hook base is stretched so that the hooks can enter the loop portion at an angle as the stretchable hook base is allowed to return to its unstretched configuration, thereby locking the hooks into the loop portion.
  • the hooks are unlocked from the loop portion by stretching the stretchable base and pulling the hooks in reverse out of the loop portion at the same angle of insertion with little production of audible sound.
  • the flexible pull features of this embodiment are especially useful in emergency closing of wounds for medical applications.
  • the hook portion is positioned adjacent to said loop portion.
  • the base is stretched and the hook portion of the stretched base is placed on the loop portion.
  • the stretched base is released so that said hooks enter said loop portion and the hook portion remains locked to the loop portion.
  • To remove the hook portion from the loop portion the base is stretched so that the hooks are unlocked and removed from the loop portion.
  • the hook portion has a plurality of first hook bases with linear first hooks attached thereto, with the first hooks attached to each of the first hook bases at a first angle, and being angled in a first direction in line with the first hook base. Lateral movement of a hook base selectively moves the hooks into and out of a loop portion.
  • the plurality of the first hook bases are attached to a first base holder wherein there is a space between each of the first hook bases.
  • the hook portion also has a plurality of second hook bases with linear second hooks attached thereto, with the second hooks attached to each of the second hook bases at a second angle, and being angled in an opposite second direction in line with the second hook base.
  • the plurality of the second hook bases are attached to a second base holder wherein there is a space between each of the second hook bases.
  • the first hook bases are slidably positioned between the second hook bases so that the first hooks overlap the second hooks when the first and the second base holders are moved towards each other, and do not overlap each other when the first and the second base holders are moved away from each other.
  • the hook portion is fastened and locked to the loop portion by moving the first and the second base holders from a non-overlapped configuration to an overlapped configuration of the first and second hooks.
  • the hook portion is unlocked and unfastened from the loop portion by moving the first and the second base holders from an overlapped configuration to a non-overlapped configuration of the first and second hooks.
  • the first base holder and the second base holder of the hook portion are placed in a non-overlapped configuration.
  • the hook portion in the non-overlapped configuration is positioned adjacent to the loop portion.
  • the first base holder and the second base holder are then placed in an overlapped configuration to lock the hook portion to the loop portion.
  • the first base holder and said second base holder are placed in a non-overlapped configuration so that the hooks are unlocked from the loop portion and the hook portion can be separated from the loop portion.
  • An advantage of the invention is a hook and loop system that generates little or no audible sound when the hook and loop portions are locked together or unlocked and separated.
  • Another advantage is effortless detachment of the hook portion from the loop portion.
  • Another advantage is that curved hooks or linear hooks can be used in the hook and loop system.
  • Another advantage is a hook and loop arrangement that provides up to 5 times more resistance to detachment when in a locked configuration compared to standard hook and loop arrangements.
  • Another advantage is a simple manual system for locking and unlocking the hook portion to the loop portion.

  • the expression "loop portion” also includes the concept of a pile. Hook and loop and hook and pile fasteners are known in the art, particularly, for example, as Velcro .
  • the hook portion 11 has a moveable hook base 13 with hooks 14 attached thereto and a hook guide 15 in which the hooks are movably inserted. Hooks 14 are flexible and are biased into a curvilinear shape so that they form up to a complete circular shape spontaneously with a spring-like function. They can also be bent into an almost complete linear shape.

Abstract

L'invention concerne un système de fixation silencieux ayant une portion crochet et une portion boucle, la portion crochet ayant une base avec des crochets fixés sur elle. La base est mobile latéralement par rapport à la portion boucle, de sorte que le mouvement latéral de la base déplace sélectivement les crochets dans et hors du guide de crochet. Les crochets sont insérés dans la portion boucle en déplaçant la base dans une première direction, de sorte que les pointes des crochets avancent dans la portion boucle. Les crochets viennent se verrouiller dans la portion boucle. Les crochets sont déverrouillés en déplaçant la base dans une seconde direction opposée, ce qui amène les boucles à se rétracter hors de la portion boucle sans production de son, de sorte que les portions crochet et boucle se séparent facilement avec une faible production de son audible. Des crochets linéaires ou incurvés peuvent être utilisés.
