[0048] Refer to the following Figures 1 to 29 Preferred forms of the invention are described. The appended claims are not limited to preferred forms, and unless expressly stated otherwise, terms and / or phrases used herein do not have a meaning other than their ordinary meaning. The terms "engage," "engaged," and "engaging" when used in conjunction with the relationship between one or more buckle abutments and one or more strap abutments refer to direct contact or relative positioning (e.g., not direct contact) that prevents the strap from loosening when a belt having a buckle and a strap is worn by an individual.

[0049] The buckle of the preferred form of the present invention does not require the known prongs that are pivotally mounted to the buckle to extend through a desired one of a plurality of holes or openings formed in the strap to secure the strap in a desired position relative to the buckle. However, if desired, the present invention may be used with a strap having a plurality of non-functional holes or openings formed in the strap to simulate a known strap. In addition, it should be noted that "belt strap" or "strap" as used herein includes any known or subsequently developed structure that is worn about the body of an individual and is operated or functioned by a buckle. The strap may be formed of any material and may have many different cross-sectional shapes. The strap may also be formed as a single piece or from multiple pieces mounted in any suitable manner. Moreover, the buckle of the present invention is not limited to the manner in which the connected end of the strap (i.e., the end opposite the free end of the strap) is mounted to the buckle. Specifically, the claimed invention is not limited to Figure 6 , Figure 7 and Fig. 9 Rather, any suitable component may be used to connect the connecting end of the strap to the buckle, including but not limited to the connectors disclosed in U.S. Patent Nos. 9,149,090; 9,351,525; and 9,918,522. Similarly, the claimed invention is not limited to Figure 6 and Figure 8 The strap shown. On the contrary, any suitable configuration of strap may be used. In addition, the buckle and strap may be formed of any suitable material, including but not limited to metal, plastic, braid, nylon, etc.

[0050] Although some preferred forms of the present invention are intended for buckles used with straps to hold an article of clothing in a desired position around an individual, the buckles disclosed herein may be used in a variety of other ways and in a variety of environments, including but not limited to buckles for backpacks, car seats, seat belts, etc., wherein one or more buckles are used with one or more securing members to removably secure the free ends of the one or more securing members to the one or more buckles.

[0051] Figures 1 to 11

[0052] Reference Figures 1 to 11 , shows a buckle A formed according to a preferred embodiment of the present invention in one of many possible configurations. Buckle A may take many forms, including but not limited to those disclosed herein.

[0053] A most preferred form of buckle A includes a body 2 having a surface 4 disposed between and extending between a first end 6 and a second end 8. Abutments 10 and 12 extend outwardly from the surface 4 and form a recess or cavity 14 between the abutments 10 and 12. However, it should be noted that one or more abutments of buckle A may extend inwardly from the surface 4 (e.g., a depression, recess, notch, etc.). Preferably, abutment 12 extends outwardly from the surface 4 a distance greater than abutment 10. The opposing inner surfaces 11 and 13 of abutments 10 and 12, respectively, preferably extend vertically or substantially vertically. The outer surfaces 15 and 17 of abutments 10 and 12, respectively, are preferably inclined and form an acute angle with the corresponding inner surfaces of abutments 10 and 12. Although abutments 10 and 12 are shown as being formed as a single piece with body 2, abutments 10 and 12 may be formed as separate pieces mounted to body 2.

[0054] For example, in Figure 1 , Figure 6 , Figure 7 and Fig. 9 As seen in FIG. 1 , buckle A includes a connector portion 16 for connecting a connection end 20 of a strap 21 to buckle A using a connector 22. The connector 22 may be removably or permanently secured to the connection end 20 of the strap 21 using one or more fasteners 24 (e.g., screws, rivets, pins, etc.). Figure 7 , the connector 22 includes a U-shaped cavity 23 for receiving the connector 16 of the band A. The connector 22 also includes a cavity 25 for receiving the connection end of the strap 21. Once the connector 22 is installed around the member 16, the fastener 24 can be inserted into the corresponding hole of the connector 22 to engage and / or penetrate the connection end of the strap 21. This connection can allow the strap 21 to pivot around the member 16.

[0055] However, any suitable connector may be used to removably connect or permanently secure the connecting end of strap 21 to buckle A.

[0056] Reference Figure 6 , Figure 8 , Fig.10 and Fig.11 , the strap 21 includes a portion 26 having a plurality of strap abutments 28. The portion 26 may be formed in any suitable portion / section or segment of the strap 21. Figure 8 , each abutment 28 preferably includes an inclined surface 30, a vertical or substantially vertical surface 27, and a horizontal or substantially horizontal surface 29 extending between surface 30 and surface 27. Moreover, abutment 28 may take any suitable configuration, including but not limited to openings, recesses, and / or notches extending partially or completely through strip 21. In the most preferred form, surface 29 is aligned or substantially aligned with inner surface 31 of strip 21.

[0057] For example, in Fig.10 As can be seen in the drawings, recess 14 formed between members 10 and 12 is configured to receive one of strap abutments 28 to prevent strap 21 from loosening. However, recess 14 may receive multiple strap abutments 28. Although portion 26 is shown as an elastomeric material connected / embedded in strap 21, strap 21 and portion 26 may be formed in any suitable manner including as a single piece. Even if one or more strap abutments 28 are placed in recess 14, the inclined surface 30 of each strap abutment 28 and the inclined surface 17 of buckle abutment 12 allow for tightening of strap 21. As shown in FIG. Fig.10 As shown, when the vertical surface 27 of the corresponding strap abutment 28 is placed in the recess 14, the strap 21 cannot be loosened.

[0058] See for example Figure 3 , Fig.10 and Fig.11 , the movable release device 40 is movably mounted around the main body 2 of the buckle A. Fig.10 and Fig.11 As shown, the movable release device 40 is in the first / non-actuated position ( Fig.10 ) and the second / actuated position ( Fig.11 ) between the parts 10 and 12 relative to the body 2. When the strap 21 is inserted through the open ends 6 and 8 and fixed to the buckle A to prevent the strap 21 from loosening, the release device 40 is located Figure 3 and Fig.10 To allow the strap 21 to loosen, the individual slides the movable release device 40 to Figure 3 and Fig.10The belt is moved to the right side of the position shown in the figure, so as to ride on or approach the buckle abutment 10, thereby disengaging the corresponding abutment of the strip 21 from the abutment of the buckle A, so as to allow the strip 21 to be moved as shown in the figure. Fig.11 Release as shown. Fig.11 As shown, the release device 40 in the second position completely blocks the recess 14. However, the release device does not need to completely or partially block the recess 14 to disengage the corresponding abutment of the strip 21 and the buckle A. Fig.14 An example of partial blocking is shown in .

[0059] In its most preferred form, the movable release device 40 is a device having a Figure 4 and Figure 5 The movable release device 40 is a flexible member having a first end 42 spaced apart from a second end 44 as shown. This configuration allows the movable release device 40 to be removably connected to the body 2 of the buckle A. However, it should be understood that the movable release device 40 can be fixed around the body 2, wherein the movable release device 40 cannot be removed from the body 2, but can be moved relative to the body 2. For example, the movable release device 40 can be a closed ring or other closed structure installed around the body 2 of the buckle A.

[0060] The movable release device 40 can be omitted so that there is no release mechanism for the buckle A. In the absence of the movable release device 40, an individual can manipulate (e.g., lift) the corresponding portion of the strap 21 to release or remove the corresponding strap abutment from the recess 14, thereby allowing the strap 21 to loosen.

[0061] like Fig.10 and Fig.11 As shown, the free end of strap 21 is inserted upward through end 6 and downward through end 8 .

[0062] Figures 12 to 15

[0063] Reference Figures 12 to 15 , shows a buckle B formed according to a preferred embodiment of the present invention in one of many possible configurations. Buckle B may take many forms, including but not limited to those disclosed herein.

[0064] A most preferred form of buckle B includes an upper surface or wall 50, a lower surface or wall 52, and opposing side walls 54 and 56 extending between and connecting the upper surface 50 to the lower surface 52, thereby forming an opening 53 extending completely through the buckle B. Figures 13 to 15, abutments 60 and 62 extend outwardly from lower surface 52 and form a recess 64 between abutments 60 and 62. However, it should be noted that one or more abutments of buckle B may extend inwardly from surface 52 (e.g., a depression, recess, notch, hole, etc.). Preferably, abutment 62 extends outwardly from surface 52 a distance greater than abutment 60. Although abutments 60 and 62 are shown as being formed as a single piece with lower surface 52, abutments 60 and 62 may be formed as separate pieces mounted to surface 52. Abutments 60 and 62 may be formed in the same or similar manner as abutments 10 and 12.

[0065] For example, in Fig.12 and Fig.13 As seen in FIG. 1 , buckle B includes a connector portion 66 for use in a manner similar to that previously used in conjunction with Figures 1 to 11 The first preferred embodiment illustrated uses a connector 22 to connect the connecting end 20 of the strap 21 to the buckle B. One or more fasteners 24 can be used to removably or permanently secure the connector 22 to the connecting end 20 of the strap 21. Moreover, any suitable connector can be used to removably connect or permanently connect or secure the connecting end of the strap 21 to the buckle B.

[0066] For example, in Fig.15 As seen in FIG. 6 , recess 64 formed between abutments 60 and 62 is configured to receive one of the strap abutments 28 to prevent strap 21 from loosening. However, recess 64 may receive a plurality of strap abutments 28. Although portion 26 is shown as being connected / embedded in the elastomeric material of strap 21, strap 21 and portion 26 may be formed as a single piece. Even if one of the strap abutments 28 is placed in recess 64, the inclined surface 30 of each strap abutment 28 and the inclined surface 69 of abutment 62 allow strap 21 to be tightened. As shown in FIG. Fig.15 As shown, when the vertical surface 27 of the corresponding strap abutment 28 is placed in the recess 64, the strap 21 cannot be loosened.

[0067] See for example Figures 12 to 15 , a movable release device 70 is movably mounted between the upper surface 50 and the lower surface 52 of the buckle B. Each opposing side wall may have an arcuate opening 72 through which an outer / exposed portion of the release device 70 extends to allow an individual to easily actuate the release device 70. A detent (e.g., a raised member / protrusion / rib) may be removably connected to each exposed portion of the release device 70 to keep the release device 70 operably connected to the buckle B while allowing the release device 70 to move / slide in each opening 72. The openings 72 are preferably configured to allow the release device 70 to be as Figures 12 to 15 As shown, the release device 70 moves to the right and rides upward in the arc-shaped opening 72. Fig.14 and Fig.15 As shown, the movable release device 70 is in the first / non-actuated position ( Fig.15 ) and the second / actuated position ( Fig.14 ) between the abutments 60 and 62. When the strap 21 is inserted through the space / opening 53 formed between the upper surface 50 and the lower surface 52 of the buckle B to prevent the strap 21 from loosening, the release device 70 is located Fig.13 and Fig.15 64. In order to release the strap 21, the individual slides the movable release device 70 to the position shown, and one of the strap abutments 28 is located in the recess 64. Fig.12 , Fig.13 and Fig.15 to the right of the position shown in the figure, so as to ride on the abutment 60 or approach the abutment 60 so as to Fig.14 The strap abutment 28 is shown disengaged / lifted / removed from the recess 64 of the buckle B to allow the strap 21 to be released.

[0068] Figures 16 to 18

[0069] Reference Figures 16 to 18 , shows a buckle C formed according to another preferred embodiment of the present invention in one of many possible configurations. Buckle C can take many forms, including but not limited to the forms disclosed herein. Buckle C can be used with strap 21 or any other appropriately formed strap.

[0070] Buckle C includes a first end 80, a second end 82, and a body 84 having a surface 86 disposed between and extending between the first end 80 and the second end 82. Buckle abutments 88 and 90 extend outwardly from the surface 86, thereby forming a recess 92 between the buckle abutments 88 and 90. The buckle abutments 88 and 90 may extend inwardly from the surface 86 (e.g., a depression, a recess, a notch, etc.). Figures 1 to 11 as well as Figures 12 to 15 As in the preferred embodiment of the present invention, the abutment portion 88 can extend outwardly from the surface 86 a distance less than the abutment portion 90.

[0071] Buckle C includes a connector portion 96 around which the connected end of the strap can be connected to buckle C by connector 22 and fastener 24 or any other suitable connector. First end 80 includes opening 100 through which the free end of strap 21 is inserted upwardly. Buckle C also includes a raised retaining member 102 that extends outwardly from surface 86 and has an opening 104 for receiving and retaining a portion of the free end of the strap after the free end of the strap is inserted through opening 104. Fig.18, the buckle C preferably includes a movable release device 110. The movable release device 110 can be used in combination with Figures 1 to 11 The form and function of the movable release device 40 are described.

[0072] The movable release device 110 may be omitted so that the buckle C does not have a release mechanism. Without the movable release device 110 , an individual may manipulate the corresponding portion of the strap 21 to release or remove the corresponding strap abutment from the recess 92 .

[0075] Buckle D includes a first end 120, a second end 122, and a body 124 having a surface 126 extending between the first end 120 and the second end 122. Preferably, a buckle abutment 128 extends outwardly from the surface 126. Moreover, the buckle abutment 128 may take any of the aforementioned forms.

[0076] Buckle D includes a connector portion 130 around which the connecting end of strap 21 can be connected to buckle D via connector 22 and fastener 24 or any other suitable connector. First end 120 includes opening 132 through which the free end of the strap is inserted upward. Second end 122 includes opening 134 through which the free end of the strap is inserted downward. Fig. 20 The buckle D further comprises a movable release device 140 slidably mounted on the body 124. The upwardly extending surface 135 of the abutment portion 128 acts with the vertical surface 27 of the corresponding strip abutment portion of the strip 21 to prevent the movable release device 140 from being moved when the movable release device 140 is located. Fig. 20 The belt strip 21 is loose when the position shown. Fig. 20 When the movable release device 140 shown moves to the left to ride on the abutment 128, the corresponding abutment of the strap 21 disengages from the abutment 128 of the buckle D, thereby allowing the strap 21 to be released. In this embodiment, the free end of the strap is inserted upward through the opening 132 and downward through the opening 134. The movable release device 140 can be taken as a combination of Figures 1 to 11 The form and function of the movable release device 40 are described.

[0077] The movable release 140 may be omitted so that there is no release mechanism for the buckle D. Without the movable release 140, an individual may manipulate the corresponding portion of the strap 21 to lift the corresponding strap abutment above the buckle abutment 128, thereby allowing the strap to be released.

[0078] Figure 22 to Figure 26

[0079] Reference Figure 22 to Figure 26 , shows a buckle E formed according to another preferred embodiment of the present invention in one of many possible configurations. Buckle E can take many forms, including but not limited to the forms disclosed herein. Buckle E can be used with strap 21 or any other appropriately formed strap.

[0080] Buckle E includes a first end 150, a second end 152, and a body 154 having a surface 156 extending between the first end 150 and the second end 152. Preferably, a buckle abutment 158 ​​extends outwardly from the surface 156.

[0081] Buckle E includes a connector portion 160 around which the connecting end of the strap can be connected to buckle E by connector 22 and fastener 24 or any other suitable connector. The first end 150 includes an opening 170 through which the free end of the strap is inserted upward. The second end 152 includes an opening 172 through which the free end of the strap is inserted downward. Buckle E also includes an opening 180 extending through the body 154. A movable release device 190 is movably / pivotally mounted in the opening 180 of the body 154. The abutment portion 158 acts with the vertical surface 27 of the corresponding strap abutment portion of the strap 21 to prevent the movable release device 190 from being moved when the movable release device 190 is moved Fig. 22 The strap 21 is loosened when the movable release device 190 is moved / pivoted to the left of the position shown, because the movement moves the release device 190 closer to the surface 156 and away from the strap 21. More specifically, when the movable release device 190 moves / pivots to Fig. 22 In the left position shown, the corresponding abutment of the strip 21 can move downward to engage with the abutment 158 ​​of the buckle E, thereby preventing the strip 21 from loosening. Conversely, when the movable release device 190 occupies the left position, the corresponding abutment of the strip 21 can move downward to engage with the abutment 158 ​​of the buckle E, thereby preventing the strip 21 from loosening. Fig. 22 In the position shown, the corresponding strip abutment of the strip 21 is lifted upward from the surface 156 to disengage the corresponding abutment of the strip 21 from the abutment 158, thereby allowing the strip 21 to be loosened. In this embodiment, the free end of the strip is inserted upward through the opening 170 and downward through the opening 172.

[0082] The movable release device 190 can be omitted so that the buckle E does not have a release mechanism. In the absence of the movable release device 190, an individual can manipulate the corresponding portion of the strap 21 to lift the corresponding strap abutment above the buckle abutment 158, thereby allowing the strap to loosen.

[0083] Fig. 27 and Fig.28

[0084] Reference Fig. 27 and Fig.28 , an article carrier F is shown in one of many possible configurations. Although the article carrier F is shown as a backpack, many other forms may be taken, including but not limited to a laptop / computer bag, a sports bag, a travel bag, a wallet, etc. The article carrier F includes a body G for receiving and storing one or more articles / objects to be carried, a pair of shoulder straps H, a closure flap I, a buckle J, and a securing member K. The buckle J may take the form of any of the aforementioned buckles or any other suitable form.

[0085] Reference Fig. 27 and Fig.28 A most preferred form of buckle J includes an upper surface or wall 200, a lower surface or wall 202, and opposing side walls 204 and 206 extending between and connecting the upper surface 200 to the lower surface 202, thereby forming an opening 208 extending completely through the buckle J. Fig.28 , the abutments 210 and 212 extend outwardly from the lower surface 202 and form a recess 214 between the abutments 210 and 212. However, it should be noted that one or more abutments of the buckle J may extend inwardly from the surface 202 (e.g., a depression, a recess, a notch, a hole, etc.). Preferably, the right abutment 212 (e.g., Fig.28 2 (shown) extends outwardly from surface 202 a distance greater than left abutment 210. Although abutments 210 and 212 are shown as being formed as a single piece with lower surface 202, abutments 210 and 212 may be formed as separate pieces mounted to surface 202. Abutments 210 and 212 may be formed in the same or similar manner as abutments 10 and 12.

[0086] The buckle J may include a connector portion 216 for connecting the end of the buckle J to the body G of the article carrier F. A fabric strip or piece may be secured around the connector portion 216 to allow an individual to move the buckle J relative to the body G. Note that the buckle J may be connected to the closure flap I opposite the body G.

[0087] like Fig.28As shown, the recess 214 formed between the abutments 210 and 212 is configured to receive one of the fixing strip abutments 218 to prevent the free end of the fixing member K from separating from the buckle J or as shown in FIG. Fig.28 Pull right as shown or Fig. 27 However, the recess 214 can receive multiple strip abutments 218. The inclined surface 230 of each strip abutment 218 and the inclined surface 232 of the abutment 212 allow the strip K to be tightened even when one of the strip abutments 218 is placed in the recess 214. Fig.28 As shown, when the vertical surface 234 of the corresponding strip abutment portion 218 is placed in the recess 214, the strip K cannot be separated from the buckle J or as shown in FIG. Fig.28 Pull right as shown or Fig. 27 Pull upward as shown.

[0088] Reference Fig.28 , a movable release device 240 is movably mounted between the upper surface 200 and the lower surface 202 of the buckle J. The movable release device 240 can be the same or similar to the release device 70. Each opposing side wall 204 can have an elongated opening similar or the same as the arcuate opening 72, and the outer / exposed portion of the release device 240 extends through the elongated opening to allow an individual to easily actuate the release device 240.

[0089] The release device 240 is in the first / non-actuated position ( Fig.28 ) and a second / actuated position relative to the abutments 210 and 212, in which the movable release device 240 is entirely or partially on the abutment 210, causing the fixing member K to move outwardly away from the lower surface 202, thereby lifting the strip abutment portion or portion 218 from the recess 214 to allow the fixing member K to be separated from the buckle J or as Fig.28 Pull right as shown or Fig. 27 Pull upward as shown.

[0090] When the strip K is inserted through the space / opening 208 formed between the upper surface 200 and the lower surface 202 of the buckle J to prevent the strip K from loosening, the release device 240 is located Fig.28 214. In order to allow the strip K to loosen, the individual slides the movable release device 240 to the position shown, and at least one of the strip abutments 218 is located in the recess 214. Fig.28 The strip abutment 218 is disengaged / lifted / removed from the recess 214 of the buckle J to allow the strip K to be separated from the buckle J or as shown in the figure. Fig.28 Pull right as shown or Fig. 27 Pull upward as shown.

[0091] Fig.29

[0092] Fig.29 Another form of a removable release device that can be used with any suitable buckle is shown. Specifically, Fig.29 The movable release 250 shown is similar to the release 40, and therefore, only the differences will be described in detail. The release 250 includes a forwardly projecting member 252 to assist in returning the release 250 to the non-actuated position. In the actuated position, the forwardly projecting member 252 is on a corresponding / adjacent buckle abutment such that the projecting member 252 is angled upwardly toward the retaining bar, providing a contact surface for a corresponding portion of the retaining bar to engage when the retaining bar is moved toward the non-actuated position, so that the release 250 is fully returned to the non-actuated position. However, the release 250 may ride up the adjacent buckle abutment a sufficient distance such that the release 250 is disposed on the uppermost surface of the adjacent buckle abutment and the member 252 extends parallel or substantially parallel to a portion of the buckle (e.g., wall 202).

[0093] Although the invention has been described as having a preferred design, it is to be understood that each and every preferred design may be further modified or adapted generally in accordance with the principles of the invention and including but not limited to modifications of the invention within the known or customary practice in the art to which the invention pertains. The claims are not limited to the preferred embodiments and have been written using the doctrine of claim differentiation to exclude such narrow constructions.
