Description

Technical Field

[0001] This invention relates to straps for attaching to objects such as suitcases, and more particularly to an easy-to-use and secure strap, and an assembly of the strap and the suitcase. Background Technology

[0002] There are two main types of traditional luggage straps. One type is secured by male and female buckles at both ends of the strap, and the other type is secured by Velcro straps (also known as Velcro).

[0003] The straps secured by male and female buckles must have an adjustable length. Users need to adjust the strap length according to the size of their suitcase so that when the strap is wrapped around the back of the suitcase, the male and female buckles can be fastened together precisely. However, adjusting the strap to the perfect length for the suitcase is actually quite difficult. If the strap is slightly too long, the strap will not be secure enough. Conversely, if the strap is slightly too short, it will be difficult for the user to fasten the male and female buckles together.

[0004] While straps secured with hook and loop fasteners don't have the problem of being difficult to adjust in length, users still need to exert considerable effort to tighten the strap before fastening the hook and loop fasteners to secure it firmly to the suitcase. However, when users pull the straps tight, if the user's pulling force is insufficient, or if the straps rotate and slide around the suitcase due to unidirectional force, it is often difficult for the user to truly tighten the straps, causing them to easily come loose. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a strap that is secured using a hook and loop fastener structure, which is convenient, labor-saving, and provides a good fastening effect.

[0006] To achieve the above objectives, this utility model provides a strap for securely encircling an object, which may be (but is not limited to) a suitcase. The strap includes a fastener having a fixing plate, a first fixing band body, and a second fixing band body; the fixing plate has a first end and a second end opposite to the first end; the first fixing band body extends outward from the first end and has a first hook-and-loop fastener; the second fixing band body extends outward from the second end and has a second hook-and-loop fastener, with the first hook-and-loop fastener and the second hook-and-loop fastener facing opposite directions; a tightening band having a loop and a tightening band body; the tightening band body has a first end, a second end opposite to the first end, and a body located between the first end and the second end and having a hook-and-loop fastener; the first end of the tightening band body is engaged with the loop, and the second end of the tightening band body passes through the loop and is engaged with the... A fixing plate is provided, which forms a loop between the loop and the first end of the tightening band, allowing it to be tightened onto an object. The fixing plate is rotatably fixed to the tightening band between a first position and a second position. When the fixing plate is in the first position, the first hook-and-loop fastener of the first fixing band is engaged with the hook-and-loop fastener of the tightening band, thus tightening the loop onto the object. When the second fixing band is pulled, causing the fixing plate to rotate from the first position to the second position, the fixing plate rotates 180 degrees around the first end as a fulcrum, and the second hook-and-loop fastener of the second fixing band is engaged with the hook-and-loop fastener of the tightening band, further tightening the loop onto the object.

[0007] Therefore, when using the strap provided by this utility model, the user can first place the loop onto the object, and then tighten the loop by pulling the fixing plate at the second end of the tightening strap. Next, the first hook-and-loop fastener of the first fixing strap is attached to the hook-and-loop fastener of the tightening strap, thus tightening and fixing the loop to the object. At this time, the fixing plate is in the first position. Then, the user can hold the second strap and pull it towards the first strap. During this pulling action, the user's pulling action will cause the second end of the fixing plate to move, forcing the fixing plate to rotate 180 degrees relative to the tightening strap, using its first end face as a fulcrum. Then, the second hook-and-loop fastener of the second fixing strap is attached to the hook-and-loop fastener of the tightening strap, firmly fixing the fastener to the tightening strap and further tightening and fixing the loop to the object. At this time, the fixing plate is in the second position. In detail, pulling the second strap forces the fixing plate to pivot and rotate (rotating 180 degrees relative to the tightening strap from the first position to the second position). Since the second end of the tightening strap is fixed to the fixing plate, the rotation of the fixing plate pulls the tightening strap relative to the loop, increasing the distance between the second end of the tightening strap and the loop, thus relatively reducing the length of the loop. In other words, the loop is tightened further, making it more securely fixed to the object. Since the aforementioned rotation of the fixing plate only requires pulling the second strap and rotating the fixing plate by lever principle, the overall operation is very convenient and effortless. Moreover, the user has already tightened the loop once when the fixing plate is in the first position, and can further tighten the loop a second time after the fixing plate is rotated and positioned in the second position. This two-stage tightening design makes the strap provided by this invention more securely and reliably fixed to the object, thereby achieving a good fastening effect.

[0008] Preferably, when the second end of the tightening band is attached to the fixing plate, it can be configured to be located between the first end and the second end of the fixing plate. Therefore, when the second band is pulled, the distance between the end face of the second end and the end face of the first end of the fixing plate (as the lever arm) will be greater than the distance between the end face of the second end of the tightening band and the end face of the first end of the fixing plate (as the resistance arm), allowing the fixing plate to be flipped with less effort. Alternatively, the second end of the tightening band can be configured to be located at the second end of the fixing plate. This allows for a larger pulling distance of the tightening band during the flipping of the fixing plate; in other words, it allows for a greater degree of second tightening of the band.

[0009] Preferably, when the fixing plate is in the second position, both the first hook-and-loop fastener surface and the second hook-and-loop fastener surface are engaged and fixed to the hook-and-loop fastener surface of the tightening band. In other words, during the flipping process of the fixing plate, the first hook-and-loop fastener surface remains engaged and fixed to the hook-and-loop fastener surface of the tightening band. Therefore, it can be ensured that the fastener will not detach from the tightening band during the entire operation, and when the fixing plate is flipped and positioned in the second position, it can be firmly engaged and fixed to the tightening band.

[0010] Preferably, the fixing plate has a first surface and a second surface opposite to the first surface; when the fixing plate is in the first position, at least a portion of the body of the tightening band located between the second end of the tightening band and the loop is pressed against the second surface of the fixing plate; when the fixing plate is in the second position, at least a portion of the body of the tightening band located between the second end of the tightening band and the loop is pressed against the second surface of the fixing plate. Thus, regardless of whether the fixing plate is in the first or second position, the fastener and the tightening band can be securely joined and fixed.

[0011] Preferably, when the fixing plate is in the second position, the first surface of the fixing plate presses against the first fixing strap. Thus, the fixing plate can securely abut against the tightening strap.

[0012] In one embodiment of this utility model, the fixing plate has a plurality of fixing holes spaced apart between the first end and the second end; the fastener includes a fixing strap, the fixing strap having a first end, a second end opposite to the first end, and a body located between the first end and the second end, the body of the fixing strap passing through the plurality of holes, such that the first end of the fixing strap extends outward from the first end of the fixing plate to form the first fixing strap body, and the second end of the fixing strap extends outward from the second end of the fixing plate to form the second fixing strap body. Thus, a fastener can be constructed by combining a single fixing strap with a fixing plate, making component manufacturing and assembly simpler and more convenient.

[0013] Preferably, the second end of the tightening band is fixed to the body of the fixing band and combined with the fixing plate. In this way, the tightening band and the fixing band can be manufactured as a single unit by means of hot-melt pressing, sewing, etc., and assembled with the fixing plate, which facilitates the manufacturing and assembly of the strap of this utility model.

[0014] Preferably, the body of the fixing strap has a third hook-and-loop fastener surface, which is located between the first end and the second end of the fixing plate and faces the same direction as the second hook-and-loop fastener surface. When the fixing plate is in the second position, the third hook-and-loop fastener surface of the fixing plate is engaged and fixed to the hook-and-loop fastener surface of the tightening strap body. This more securely positions and fixes the fixing plate in the second position, preventing it from detaching from the tightening strap.

[0015] In another embodiment of this utility model, the first fixing strap is fixed to the first end of the fixing plate, the second fixing strap is fixed to the second end of the fixing plate, and the second end of the tightening strap is fixed between the first end and the second end of the fixing plate. Thus, the first and second fixing straps and the second end of the tightening strap can be directly fixed to the fixing plate using methods such as heat fusion pressing, sewing, or fasteners, facilitating component manufacturing and assembly.

[0016] This utility model also provides an assembly of a strap and a suitcase, comprising the strap and the suitcase, wherein the strap is secured to the suitcase by the drawstring. Thus, the user can easily and effortlessly secure the strap around the suitcase, effectively preventing accidental opening of the suitcase.

[0021] Please refer to the following: Figures 1 to 4 As shown, the strap 10 provided in the first preferred embodiment of this utility model includes a retainer 20 and a tightening strap 50.

[0022] The fastener 20 includes a fastening plate 22, a first fastening strap 24, and a second fastening strap 26. The fastening plate 22 is generally rectangular, having a first end 221 and a second end 223 opposite to the first end 221. The first fastening strap 24 is attached to the first end 221 and extends outward from it, having a first hook-and-loop fastening surface 241. The second fastening strap 26 is attached to the second end 223 and extends outward from it in the opposite direction to the first fastening strap 24, having a second hook-and-loop fastening surface 261. The first hook-and-loop fastening surface 241 and the second hook-and-loop fastening surface 261 face opposite directions, for example, with... Figure 1 For example, the first hook and loop fastener 241 faces the direction perpendicular to and into the drawing, while the second hook and loop fastener 261 faces the direction perpendicular to and away from the drawing.

[0023] In detail, in this embodiment, the fixing plate 22 can be made of engineering plastic or metal, and has a first surface 225, a second surface 227 opposite to the first surface 225, and a plurality of fixing holes 229 located between the first end 221 and the second end 223, arranged in parallel at intervals and passing through the first surface 225 and the second surface 227. Furthermore, the fastener 20 also includes a fixing strap 23, which is a strap with a hook-and-loop fastener on one side and a smooth surface on the other. The fixing strap 23 has a first end 231, a second end 233 opposite to the first end 231, and a body 235 located between the first end 231 and the second end 233. The body 235 of the fixing strap 23 passes through and is engaged in multiple fixing holes 229 in sequence, so that the fixing strap 23 can be relatively fixed to the fixing plate 22. Furthermore, the first end 231 of the fixing strap 23 extends outward from the second surface 227 of the first end 221 of the fixing plate 22, thereby forming the first fixing strap body 24. The second end 233 of the fixing strap 23 extends outward from the second surface 227 of the second end 223 of the fixing plate 22, thereby forming the second fixing strap body 26. In addition, the body 235 of the fixing strap 23 forms two third hook-and-loop fastener surfaces 237 on the first surface 225 of the fixing plate 22, located between the first end 221 and the second end 223 of the fixing plate 22. At this time, the first hook-and-loop fastener surface 241 and the second surface 227 face the same direction, while the second hook-and-loop fastener surface 261 and the third hook-and-loop fastener surface 237 face the same direction as the first surface 225.

[0024] The tightening band 50 has a loop 60 and a tightening band body 70. The loop 60 is made of reinforced plastic or metal and has a first side 51, a second side 53 opposite to the first side 51, and a perforation 55 located in the center. The tightening band 70 is a band with a hook-and-loop fastener 70a on one side and a smooth surface on the other. It has a first end 71, a second end 73 opposite to the first end 71, and a body 75 located between the first end 71 and the second end 73. The first end 71 of the tightening band 70 is attached to the first side 51 of the ring 60 by stitching or other feasible methods such as heat fusion or fastening. The second end 73 of the tightening band 70 passes through the perforation 55 of the ring 60 and is attached to the body 235 of the fixing band 23 by stitching or other feasible methods such as heat fusion. Thus, the second end 73 of the tightening band 70 is attached to the fixing plate 22, located between the first end 221 and the second end 223 of the fixing plate 22. The body 75 of the tightening band 70 wraps around the second side 53 of the ring 50, causing the body 75 located between the ring 50 and the first end 71 to form a band that can be tightened onto an object (e.g., Figure 5 The drawstring 77 on the suitcase 80 shown, and the body 75 located between the loop 50 and the second end 73 extends partially below the second surface 227 of the fixing plate 22 (as shown). Figure 4 (As shown).

[0025] It should be further explained that, in this embodiment, the first hook-and-loop surface 241 and the second hook-and-loop surface 261 have a hook-shaped structure with multiple hook portions (i.e., commonly known as the hook face), while the hook-and-loop surface 70a of the tightening band 70 has a loop-shaped structure with multiple loop portions (i.e., commonly known as the loop face), so that the first hook-and-loop surface 241 and the second hook-and-loop surface 261 can be hooked and fixed to the hook-and-loop surface 70a of the tightening band 70 respectively. The hook-shaped structure of the first hook-and-loop surface 241 and the second hook-and-loop surface 261 and the loop-shaped structure of the hook-and-loop surface 70a of the tightening band 70 are the same as the traditional hook-and-loop tape structure (i.e., commonly known as Velcro), so they are only schematically shown in the accompanying drawings of this application. Secondly, the hook-shaped structure of the first hook-and-loop fastener 241 and the second hook-and-loop fastener 261, as well as the hook-and-loop fastener 70a of the tightening band 70, can be achieved not only by using the traditional hook-and-loop fastener structure, but also by using other types of hook-and-loop fastener structures (such as the Dual Lock fastener manufactured and sold by 3M).

[0026] Through the above-mentioned technical features, especially the mutual fastening and fixing of the first hook-and-loop fastener 241 and the hook-and-loop fastener 70a of the tightening strap body 70, and further the mutual fastening and fixing of the second hook-and-loop fastener 261 and the hook-and-loop fastener 70a of the tightening strap body 70, the fixing plate 22 can be fixed at the first position P1 ( Figure 5 , Figure 7A (Refer to) and the second position P2 ( Figure 6 , Figure 7C The straps 10 are flipped and fixed relative to each other on the tightening strap 50, thereby securing the straps 10 tightly to the object (e.g., reference). Figure 5 , Figure 6 The suitcase shown is 80). Among them, such as... Figure 5 and Figure 7A As shown, when the fixing plate 22 is in the first position P1, the first hook and loop surface 241 of the first fixing strap 24 is engaged and fixed to the hook and loop surface 70a of the tightening strap 70, so that the loop 77 can be initially tightened and fixed to the object. Secondly, when the fixing plate 22 is in the first position P1, the second fixing strap 26 can be pulled to flip the fixing plate 22 of the fixing device 20 from the first position P1 to the second position P2. During the process, the fixing plate 22 will be flipped 180 degrees with the end face of the first end 221 as the fulcrum, and the second hook and loop surface 261 of the second fixing strap 26 is engaged and fixed to other positions of the hook and loop surface 70a of the tightening strap 70, so that the loop 77 is further tightened and fixed to the object.

[0027] The following will describe in more detail the usage, operating principle, and effects of the strap 10 provided in this application. When using the strap 10 provided by this utility model, the user can first place the roughly adjusted loop 77, tailored to fit the size of the object, onto the object. Then, the user can pull the loop 77 as tightly as possible by pulling the fixing plate 22, which is connected to and fixed to the second end 73 of the tightening strap 70. That is, the user holds the fixing device 20 and pulls it as far away from the loop 60 as possible, so that the loop 77 can tightly bind the object. Then, the first hook-and-loop fastener 241 of the first fixing strap 24 is connected and fixed to the hook-and-loop fastener 70a of the tightening strap 70. In this way, the loop 77 is tightened and fixed to the object for the first time. At this time, the fixing plate 22 is located at the first position P1. Figure 5 and Figure 7A As shown. Then, with the fixing plate 22 in the first position P1, the user can further grasp the second strap 26 and pull the second strap 26 towards the first strap 24. Figure 7B As shown, during the pulling of the second belt 26, the user's pulling action will cause the second end 223 of the fixing plate 22 to move outward, and force the fixing plate 22 to rotate 180 degrees relative to the tightening belt 70 with its first end 221 as the fulcrum. At this time, the distance between the end face of the second end 223 of the fixing plate 22 and the end face of the first end 221 can be regarded as the lever arm, and the distance between the second end 73 of the tightening belt 70 and the end face of the first end 221 of the fixing plate 22 can be regarded as the resistance arm. At this time, the lever arm is greater than the resistance arm, so the user can rotate the fixing plate 22 180 degrees with less effort by means of the lever principle. Figure 7CAs shown, the second hook and loop surface 261 of the second fixing strap 26 can then be attached to the hook and loop surface 70a of the tightening strap 70, so that the fixing device 20 is firmly fixed to the tightening strap 70, and the loop 77 is further tightened (for the second time) and fixed to the object. At this time, the fixing plate 22 is located in the second position P2.

[0028] As can be seen from the above description, when the fixing plate 22 of the strap 10 provided by this utility model is in the first position P1, the fixing plate 22 can be forced to rotate and pivot (rotate 180 degrees relative to the tightening strap 70 from the first position P1 to the second position P2) by pulling the second strap 26. Since the second end 73 of the tightening strap 70 is fixed to the fixing plate 22, during the rotation of the fixing plate 22, the tightening strap 70 will be pulled to slide relative to the ring 60, thereby increasing the distance between the second end 73 of the tightening strap 70 and the ring 60, and relatively reducing the length of the loop 77. In this way, the loop 77 is tightened further, so that the loop 77 can be more firmly fixed to the object. Since only the second strap 26 needs to be pulled during the flipping of the fixing plate 22, and the fixing plate 22 is flipped by lever principle, the overall operation is very convenient and labor-saving. Moreover, when the fixing plate 22 is in the first position P1, the user has already tightened the loop 77 for the first time. After the fixing plate 22 is flipped and positioned in the second position P2, the loop 77 will be tightened further (for the second time). In other words, the strap 10 provided by this application has a two-stage tightening loop 77 design, which makes the strap 10 more stable and reliable to be fixed to the object, thereby achieving a good fastening effect and realizing the creative purpose of this application.

[0029] The following will further explain the usage details of the strap 10 provided in this application. For example... Figure 7C As shown, when the fixing plate 22 is in the second position P2, the first hook-and-loop fastener 241 and the second hook-and-loop fastener 261 are engaged and fixed at different positions of the hook-and-loop fastener 70a of the tightening band 70. In other words, during the process of the fixing plate 22 rotating 180 degrees, the first hook-and-loop fastener 241 is still engaged and fixed to the hook-and-loop fastener 70a of the tightening band 70. Therefore, it can be ensured that the fastener 20 will not detach from the tightening band 70 during the entire operation, and when the fixing plate 22 is rotated and positioned in the second position P2, it can be firmly engaged and fixed to the tightening band 70.

[0030] Secondly, such as Figure 7A As shown, when the fixing plate 22 is in the first position P1, a portion of the body 75 of the tightening strap 70, located between the second end 73 of the tightening strap 70 and the loop 60, is pressed against the second surface 227 of the fixing plate 22; and as Figure 7CAs shown, when the fixing plate 22 is in the second position P2, a portion of the body 75 of the tightening strap 70, located between the second end 73 of the tightening strap 70 and the loop 60, presses against the second surface 227 of the fixing plate 22. Furthermore, the first surface 225 of the fixing plate 22 presses against the first fixing strap 24. Additionally, the third hook-and-loop fastener 237 is fixed to the hook-and-loop fastener 70a of the tightening strap 70. Therefore, regardless of whether it is the first position P1 or the second position P2, the fastener 20 and the tightening strap 50 can be securely fixed together.

[0031] See also Figure 8 , Figure 8 The second preferred embodiment of this utility model discloses a strap 90. The structure of the strap 90 is generally the same as that of the strap 10 provided in the first embodiment. The difference is that in this embodiment, the first fixing strap 24 is a single strap and is directly attached to the first end 221 of the fixing plate 22 by sewing or other feasible methods such as heat fusion pressing or fastening. Similarly, the second fixing strap 26 is also a single strap and is directly attached to the second end 223 of the fixing plate 22 by sewing or other feasible methods such as heat fusion pressing or fastening. The second end 73 of the tightening strap 70 is also directly attached to the space between the first end 221 and the second end 223 of the fixing plate 22 by sewing or other feasible methods such as heat fusion pressing or fastening. Thus, the strap 90 provided in this embodiment can also achieve the creative purpose of this utility model, and provides a different component composition and assembly method than the strap 10 provided in the first preferred embodiment, so as to adapt to various different component production and assembly processes.

[0032] Finally, it must be stated again that the constituent elements disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of patent protection of this utility model. Substitutions or variations of other equivalent elements should also be covered by the scope of the claims of this utility model.
