DETAILED DESCRIPTION
[0040] It has been found through research that, although easy to implement and flexible in use, the conventional methods for fastening a MOLLE accessory do not allow angular adjustment, may present difficulties when a military person or police officer is trying to attach a MOLLE accessory to a carrier (e.g., a leather belt, a duty belt, an equipment belt, a ring fastener sewn on a piece of clothes or on a backpack, etc.) worn on their body, and may render the attached MOLLE accessory prone to getting loose or falling off while the military person or police officer is on duty, either because of an external force (e.g., a shaking, swinging, colliding, or pulling force), or because of elastic fatigue of the materials used, or because of wear or damage of related elements (e.g., the foregoing hooking portion 320 or engaging wall 360). As a result of extensive study and repeated experiments, the present disclosure presents a “load-carrying fastener with rapid attachment/detachment and safety lock mechanisms” as shown in FIG. 9, so that a military person or police officer may use the load-carrying fastener as a connection medium between a MOLLE accessory and a carrier. The structures of the load-carrying fastener in the present disclosure includes any structures that serve as the rapid attachment and detachment and safety lock mechanisms of a load-carrying fastener, which allows a military person or police officer to easily, rapidly, and securely attach various MOLLE accessories to a carrier so that the military person or police officer can carry those MOLLE accessories with them and use the MOLLE accessories whenever needed to tackle an emergency taking place while the military person or police officer is on duty.
[0041] Referring to FIG. 9, in certain embodiments, a load-carrying fastener 9 can be applied to an attachable holder M (e.g., the sheath of a hunting knife, a police baton holder, the protective holder of a handheld transceiver, a gun holster, etc.) for storing a MOLLE accessory (not shown, e.g., a handgun, hunting knife, taser, police baton, handheld transceiver, etc.). A lateral side of the attachable holder M is formed with a storage opening M0 so that the MOLLE accessory can be passed through the storage opening M0 and then stored and fastened in a receiving space M1 formed in the attachable holder M. The rear side of the attachable holder M is formed with a first connecting portion M2. The first connecting portion M2 not only allows different MOLLE accessories to be securely attached through their respective attachable holders M to a carrier (e.g., a leather belt, a duty belt, an equipment belt, a ring fastener sewn on a piece of clothes or on a backpack, etc.) whose specifications (e.g., width) may vary and which is worn on the body of a military person or police officer, but also allows the angle between each MOLLE accessory and the carrier to be adjusted to the optimal operation angle to meet practical needs, the objective being to enable the military person or police officer to take whichever MOLLE accessory needed (e.g., a hunting knife, police baton, handheld transceiver, handgun, etc.) out of its attachable holder M rapidly and precisely. To facilitate description of the relative positions and connection relationships of the various elements and structures of the load-carrying fastener 9, the “rear side” of the load-carrying fastener 9 is defined as the side facing the lower left corner of each of FIG. 9 to FIG. 13, and the “front side” of the load-carrying fastener 9 is defined as the side facing the upper right corner of each of FIG. 9 to FIG. 13.
[0042] In certain embodiments, referring to FIG. 9, the load-carrying fastener 9 includes a fastener base 90 and a pivotable locking plate 91. The fastener base 90 includes a plate base body 900 integrally formed of a plasticized material. Each of two lateral sides of the plate base body 900 is formed with an elastic arm 901 that extends toward the top side of the plate base body 900. Compression-recoil gaps 902 are formed between the elastic arms 901 and the plate base body 900. Each compression-recoil gap 902 allows the corresponding elastic arm 901 not only to be subjected to an elastic force that pushes the corresponding elastic arm 901 toward the other elastic arm 901, but also to an elastic force that pushes the corresponding elastic arm 901 further away from the other elastic arm 901.
[0043] A lock-release space 903 is formed between corresponding inner portions of the elastic arms 901 that are respectively adjacent to the top side of the elastic arms 901. The side of each elastic arm 901 that faces the lock-release space 903 is concavely provided with at least one first engaging unit 9013 (e.g., at least one engaging groove) (or is protrudingly provided with at least one first engaging unit 9013 such as at least one engaging tenon) adjacent to the top edge of the elastic arm 901. The rear side of the plate base body 900 is formed with a second connecting portion 904 adjacent to the top side of the plate base body 900. The configuration of the second connecting portion 904 matches that of the first connecting portion M2 so that the attachable holder M can be fastened (or pivotally connected) to the plate base body 900 through the first connecting portion M2 and the second connecting portion 904, allowing a military person or police officer to store the MOLLE accessory to be used on duty in the attachable holder M, to carry the MOLLE accessory with them conveniently, and to use the MOLLE accessory whenever needed to deal with an emergency or crisis that occurs while the military person or police officer is on duty.
[0044] With continued reference to FIG. 9, the top side of each elastic arm 901 is formed with a locking arm 9011 that extends rearward of the elastic arm 901, and the free end of each locking arm 9011 is formed with a locking hook 9012. Referring to FIG. 10, the pivotable locking plate 91 includes a plate body 910 integrally formed of a plasticized material. The plate body 910 matches the plate base body 900 in configuration so that the bottom end of the plate base body 900 and the bottom end of the plate body 910 can be pivotally connected, allowing the plate body 910 to be flipped open from, and closed back on, the rear side of the plate base body 900 (as indicated by the double-headed arrow in FIG. 10). The pivotable locking plate 91 is formed with two locking holes 911 that are adjacent to the top edge of the pivotable locking plate 91 and correspond in position to the locking arms 9011, respectively, and hence the locking hooks 9012, respectively. Each locking hole 911 matches the corresponding locking arm 9011 and corresponding locking hook 9012 in configuration so that when the plate body 910 is closed on the rear side of the plate base body 900, referring to FIG. 10 and FIG. 11, each locking arm 9011 can be inserted into the corresponding locking hole 911 to hook the corresponding locking hook 9012 to the hole edge of the corresponding locking hole 911, thereby keeping the plate body 910 in a “locked state”, in which the plate body 910 is closed on the rear side of, and combined as a whole with, the plate base body 900, and in which the plate body 910 and the plate base body 900 can securely clamp a carrier therebetween, as shown in FIG. 12. Only when the pressing portions P (each of which is provided on the outer side, and adjacent to the top side, of one of the elastic arms 901) are pressed simultaneously (as indicated by the two opposing arrows in FIG. 13), for example, by a military person or police officer using the load-carrying fastener 9, to bring the elastic arms 901 closer to each other and thereby move and disengage each locking hook 9012 away from the position where it is hooked to the hole edge of the corresponding locking hole 911 will the plate body 910 be brought back to the “unlocked state”, in which the plate body 910 can be flipped open from the rear side of the plate base body 900. The foregoing configurations ensure that the load-carrying fastener 9 can be rapidly and securely attached to the carrier worn on the body of a military person or police officer, allowing the military person or police officer to store the MOLLE accessories to be used on duty in their respective attachable holders M, to carry those MOLLE accessories with them conveniently, and to use the MOLLE accessories whenever needed to deal with an emergency or defuse an imminent crisis.
[0045] To further keep the fastener base 90 and the pivotable locking plate 91 of the load-carrying fastener 9 closed with respect to each other after the fastener base 90 and the pivotable locking plate 91 are clamped on a carrier (i.e., to keep the fastener base 90 and the pivotable locking plate 91 clamped on, or locked to, the carrier and hence in an “interlocked state”, in which the fastener base 90 and the pivotable locking plate 91 cannot be separated from each other), regardless of the conditions the load-carrying fastener 9 may be in (e.g., being violently shaken, swung, hit, pulled, etc.), in certain embodiments, referring to FIG. 9, the load-carrying fastener 9 further includes a lock-release key 92. As shown in FIG. 9 and FIG. 10, the rear side of the lock-release key 92 can be pivotally connected to the top edge of the plate body 910, and the lock-release key 92 matches the lock-release space 903 in configuration so that when the pivotable locking plate 91 is closed on the rear side of the plate base body 900 and hence combined as a whole with the fastener base 90 (i.e., in the locked state), referring to FIG. 11, the lock-release key 92 can be flipped forward (as indicated by the arrow in FIG. 11) to a locking position, where the lock-release key 92 is engaged in the lock-release space 903. Referring to FIG. 9 and FIG. 10, each of the two lateral end edges of the lock-release key 92 is protrudingly provided with at least one second engaging unit 920 (e.g., at least one engaging tenon) (or is concavely provided with at least one second engaging unit 920 such as at least one engaging groove), and the second engaging units 920 match the first engaging units 9013 in configuration so that each second engaging unit 920 and the corresponding first engaging unit 9013 can engage with each other, as shown in FIG. 12, thereby further keeping the pivotable locking plate 91 and the fastener base 90 securely coupled together, i.e., in a further “interlocked state”. Unless the lock-release key 92 is flipped rearward (as indicated by the middle arrow in FIG. 13) back to a “released state”, in which the lock-release key 92 is not engaged in or disengaged from the lock-release space 903, the pivotable locking plate 91 and the fastener base 90 will stay in the “interlocked state”, in which the pivotable locking plate 91 and the fastener base 90 are closed with respect to, and cannot be separated from, each other. It is thus ensured that, once clamped on a carrier, the load-carrying fastener 9 will in no circumstances (be they violent shaking, swinging, collision, pulling, etc.) get loose or fall off from the carrier and thus hinder the performance of duty. In certain embodiments however, the first engaging units 9013 and the second engaging units 920 may be dispensed with, as long as the lock-release key 92 can be flipped into engagement in the lock-release space 903 to keep the pivotable locking plate 91 and the fastener base 90 in the interlocked state.
[0046] Moreover, in order to further adapt the load-carrying fastener 9 to differently sized carriers that may be worn by a military person or police officer, in certain embodiments, referring to FIG. 9 and FIG. 10, a portion of the plate base body 900 along a direction away from the second connecting portion 904 is formed with a plurality of rows of spacing-adjusting insertion hole sets 905. The rows are arranged in the transverse direction of the plate base body 900 and are parallel to one another. As shown in FIG. 14, the spacing-adjusting insertion hole set 905 in each row includes a left insertion hole 905L, a central insertion hole 905C, and a right insertion hole 905R. The insertion holes 905L, 905C, and 905R in each row are transversely arranged. Each of the left insertion hole 905L and the right insertion hole 905R is formed with a hooking wall 9051 on the inner wall thereof. Referring to FIG. 10 and FIG. 14, in certain embodiments, the load-carrying fastener 9 includes a spacing-adjusting insertion member 93. The spacing-adjusting insertion member 93 is integrally formed of a plasticized material (e.g., rubber, etc.) and includes a left insertion member 93L, a central insertion member 93C, and a right insertion member 93R. The insertion members 93L, 93C, and 93R are transversely arranged, and each of the left and right insertion members 93L and 93R is connected to the left or right side of the central insertion member 93C by an elastic arm 930. The left and right insertion members 93L and 93R match the left and right insertion holes 905L and 905R in configuration respectively, and the front side of each of the left and right insertion members 93L and 93R is protrudingly formed with a locking hook 9310. The locking hooks 9310 match the hooking walls 9051 in configuration so that when the insertion members 93L, 93C, and 93R are inserted into a selected set of the insertion holes 905L, 905C, and 905R respectively, each locking hook 9310 is hooked to the corresponding hooking wall 9051. Thus, depending on a military person or police officer's choice and the specifications of the carrier in use, the spacing-adjusting insertion member 93 allows a clamping space R not only to be easily, rapidly, and precisely formed between the fastener base 90 and the pivotable locking plate 91 and between the spacing-adjusting insertion member 93 and the locking arms 9011, but also to be adequately sized to receive the carrier clamped between the fastener base 90 and the pivotable locking plate 91 (i.e., to match the specifications of the carrier). In other words, regardless of the specifications of the carrier, the military person or police officer will always be able to insert the spacing-adjusting insertion member 93 easily, rapidly, and precisely into the spacing-adjusting insertion hole set 905 corresponding to the specifications of the carrier and then clamp the carrier rapidly and securely between the fastener base 90 and the pivotable locking plate 91. This design allows a MOLLE accessory for use by a military person or police officer on duty to be securely inserted into its attachable holder M hung on the load-carrying fastener 9, to be carried around by the military person or police officer with ease, and to be used whenever needed to deal with an emergency that occurs while the military person or police officer is on duty; moreover, when properly attached to the carrier in use as a whole, the load-carrying fastener 9, the attachable holder M, and the MOLLE accessory will in no circumstances become loose, fall off, or get lost.
[0047] In certain embodiments, in order to lock the load-carrying fastener 9 even more securely to the carrier worn by a military person or police officer, and further ensure that the load-carrying fastener 9 will not get loose or fall off in any circumstances (e.g., when violently shaken, swung, hit, pulled, etc.; when the materials used undergo elastic fatigue; when related elements (e.g., the foregoing hooking portion 320 or engaging wall 360) are worn or damaged; etc.), referring to FIG. 9 and FIG. 10, the front side of the pivotable locking plate 91 is formed with a plurality of rows of positioning hole sets 915. The rows are arranged in the transverse direction of the pivotable locking plate 91 and correspond in position to the plurality of rows of insertion hole sets 905 respectively. As shown in FIG. 10, the positioning hole set 915 in each row includes a left positioning hole 915L, a central positioning hole 915C, and a right positioning hole 915R. The positioning holes 915L, 915C, and 915R in each row are transversely arranged. Referring to FIG. 14, the rear side of each of the left insertion member 93L, the central insertion member 93C, and the right insertion member 93R is protrudingly formed with a positioning post 9320, and the positioning posts 9320 match each positioning hole set 915 in configuration so that after the insertion members 93L, 93C, and 93R are inserted into a selected set of insertion holes 905L, 905C, and 905R respectively, and the fastener base 90 and the pivotable locking plate 91 are closed with respect to, and combined as a whole with, each other around a carrier, the spacing-adjusting insertion member 93 is securely positioned at a predetermined position and will not get loose or be displaced. This ensures that the load-carrying fastener will stay securely hung on the carrier.
[0048] In certain embodiments, the spacing-adjusting insertion member 93 is made of a material with higher elasticity than the plate base body 900 and the plate body 910 so that a military person or police officer can insert the spacing-adjusting insertion member 93 into the fastener base 90 and pull the spacing-adjusting insertion member 93 away from the fastener base 90 with greater ease and rapidity to enable fast and precise adjustment of the clamping space R between the fastener base 90 and the pivotable locking plate 91 according to the specifications of the carrier worn on the body of the military person or police officer, thereby allowing the load-carrying fastener 9 to be clamped on the carrier rapidly and securely, and a MOLLE accessory needed for duty to be inserted securely into the corresponding attachable holder M hung on the load-carrying fastener 9, to be carried around by the military person or police officer conveniently, and to be used whenever needed to tackle an emergency taking place while the military person or police officer is on duty. When properly attached to the carrier as a whole, the load-carrying fastener 9, the attachable holder M, and the MOLLE accessory will therefore in no circumstances become loose, fall off, or get lost.
