A type of interlocking zipper pull and its locking structure

Abstract

This utility model discloses an interlocking zipper pull and its locking structure, relating to the field of zipper technology. The interlocking zipper pull locking structure includes two plates, each of which is provided with an interlocking structure. The interlocking structure includes a connecting arm and an interlocking member. The connecting arm is located on the first end face of the second plate facing away from the first plate and partially extends from the front end of the second plate to form an extension. The extension is inclined away from the second plate to leave a clearance space between it and its first end face. The extension is provided with an interlocking member. The interlocking members on the two plates are connected, which can interlock the two plates together facing each other along the length direction of the zipper pull. In the interlocked state, the two interlocking members can rotate relative to each other around the width direction of the zipper pull. This rotation causes the extension on one plate to abut against the first end face of the second plate on the other plate through the clearance space, so that the planes where the two second plates are located form an angle, thus maintaining the interlocking state of the two interlocking members. This allows the interlocking zipper pull to bend the zipper in the interlocked state.

Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and more specifically, to an interlocking zipper pull and its locking structure. Background Technology

[0002] Existing backpacks and tents typically use double-zipper pulls, where the two pulls can be connected to each other. However, the zipper pulls currently used are mostly attached to the zipper body. Figure 1 The structure shown has a zipper pull that lacks locking force, making it impossible to maintain a locked state during use, as illustrated in the attached figure. Figure 2 As shown, even after the double zipper pulls are closed on the chain teeth, they still cannot maintain a locked state on the chain teeth. As a result, during daily use, external forces such as squeezing and friction can cause the closed double zipper pulls to open.

[0003] In existing technologies, an interlocking structure is typically added to the pull tabs of double-pull heads to keep the pull heads locked together. However, in the process of developing this invention, the inventors discovered at least the following problems in the existing technology:

[0004] 1. When interlocking zipper pulls pass through curved zippers, such as at the corners of backpacks, there may be jamming or loss of lock. In addition, interlocking zipper pulls usually have difficulty passing through curved zippers while in an interlocked state.

[0005] 2. The interlocking structure is exposed on the pull tab, which is not concealed enough, and items in the backpack or tent are still at risk of being stolen.

[0006] 3. The interlocking structure on the pull tab cannot completely guarantee the closed state of the double pull heads, and there will be a certain gap.

[0007] Therefore, how to solve any of the above-mentioned problems of existing interlocking zipper heads is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide an interlocking zipper head locking structure that can ensure that the two zipper heads remain interlocked when the zipper is bent.

[0009] Another objective of this invention is to provide an interlocking zipper puller that includes the aforementioned interlocking zipper puller locking structure.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A locking structure for interlocking zipper pulls is used to lock two zipper pulls together. It includes two plates, each of which includes a first plate and a second plate that are opposite to each other and spaced apart. Both plates are also provided with an interlocking structure.

[0012] The interlocking structure includes a connecting arm and an interlocking component. The connecting arm is disposed on the first end face of the second plate facing away from the first plate and extends partially from the front end of the second plate to form an extension. The extension is inclined away from the second plate to leave clearance space between it and the plane where the first end face is located, and the extension is also provided with the interlocking component.

[0013] The interlocking components on the two plates are connected, which can interlock the two plates together facing each other along the length direction of the pull head. In the interlocked state, the two interlocking components can also rotate relative to each other around the width direction of the pull head. Through the rotation, the protruding part on one plate can abut against the first end face of the second plate on the other plate through the clearance space, so that the planes where the two second plates of the two plates are located form an included angle, thus maintaining the interlocking state of the two interlocking components.

[0014] Preferably, the protrusion is provided as an inclined surface adjacent to the end face of the second plate along the thickness direction of the pull head, and the inclined surface extends from the front end of the second plate to the front end of the connecting arm and gradually slopes away from the second plate.

[0015] Preferably, the front end face of the connecting arm is an arc surface, and the arc surface connects the inclined surface and the end face of the protrusion away from the second plate along the thickness direction of the pull head.

[0016] Preferably, the interlocking member is disposed on one side of the protrusion along the width direction of the pull head.

[0017] Preferably, the interlocking component is a hook block, and the hook block has an interlocking arc surface on one side away from the front end edge of the connecting arm along the length direction of the pull head. The interlocking arc surface extends from one end face of the protrusion to the other end face along the thickness direction of the pull head.

[0018] Preferably, the hook block has a hook block arc surface on the side away from the connecting arm along the width direction of the pull head, and the hook block arc surface extends from the front end edge of the connecting arm to the side of the interlocking arc surface away from the connecting arm.

[0019] Preferably, the second plate is located below the first plate, and the front end of the second plate has symmetrical notches on both sides along the width direction of the pull head.

[0020] Preferably, the first plate and the second plate are both plate sleeve structures, and are respectively used to sleeve the upper wing plate and the lower wing plate of the pull body of the pull head;

[0021] Alternatively, the second plate with the interlocking structure is a plate sleeve structure, which is used to sleeve the lower wing plate of the pull body of the pull head.

[0022] An interlocking zipper pull includes two pull bodies and the aforementioned interlocking zipper pull locking structure. Each of the two pull bodies includes an upper wing plate and a lower wing plate. The upper wing plate and the lower wing plate are respectively fitted with a first plate and a second plate, which are both plate-sleeve structures in the plate body.

[0023] A type of interlocking zipper includes two zipper bodies, each of which includes an upper wing plate and a lower wing plate, and each of the lower wing plates is fitted with a second plate that is a plate-sleeve structure.

[0024] An interlocking structure protrudes from the lower surface of each of the second plates;

[0025] The interlocking structure includes a connecting arm and an interlocking member. The connecting arm is located on the lower surface of the second plate near the front end of the pull body, and extends partially from the second plate and beyond its front end edge to form a protrusion. The protrusion is inclined away from the second plate to leave clearance space between it and the plane where the lower surface of the second plate is located, and the protrusion is also provided with the interlocking member.

[0026] The interlocking components on the two second plates are connected so that the two pull bodies can be interlocked together along the length direction of the pull bodies. In the interlocked state, the two interlocking components can also rotate relative to each other around the width direction of the pull bodies. Through the rotation, the protrusion on one second plate can abut against the lower surface of the other second plate through the clearance space, so that the planes where the two second plates are located form an angle, thus maintaining the interlocking state of the two interlocking components.

[0027] The interlocking zipper lock structure provided by this utility model is used to lock two zipper heads together to form an interlocking zipper head. The zipper head usually includes a pull body. In practical applications, the two plates in the interlocking zipper lock structure can directly replace the pull bodies in the two zipper heads, or the two plates in the interlocking zipper lock structure can be fixed to the pull bodies in the two zipper heads respectively.

[0028] Both plates are equipped with an interlocking mechanism. In each plate structure, a connecting arm is located on the first end face of the second plate facing away from the first plate and partially extends from the front end of the second plate to form a protrusion. The protrusion is inclined away from the second plate to leave clearance space between it and its first end face, and the protrusion is also equipped with an interlocking component. In this way, by joining the two plates together along the length of the slider and connecting the interlocking components on them, the two plates can be locked together, thereby achieving interlocking of the two sliders.

[0029] In a further technical solution, taking the arrangement of the first and second plates from top to bottom as an example, the two plates are interlocked. In the interlocked state, the interlocking components on both plates can rotate relative to each other around the width of the zipper pull. Furthermore, a clearance space is provided between the protruding portion of the second plate on each plate and its bottom surface, allowing for rotation of the protruding portion of the second plate on the other plate. Thus, when the two zipper pulls pass through a curved zipper, the interlocking components on one plate rotate relative to each other while remaining locked. Simultaneously, the protruding portion on one plate can tilt upwards to abut against the bottom surface of the second plate on the other plate, creating an angle between the planes containing the two second plates. This maintains the interlocking state of the two interlocking components, ensuring that after the two zipper pulls are interlocked, they can smoothly pass through the curved zipper while maintaining the interlocked state, preventing jamming and loss of lock.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] The core of this utility model is to provide an interlocking zipper head locking structure, which can ensure that the two zipper heads remain interlocked when the zipper is bent.

[0049] Another core aspect of this utility model is to provide an interlocking zipper head that includes the aforementioned interlocking zipper head locking structure.

[0050] It should be noted that, in this embodiment, the length direction of the pull head is the same as the length direction of the pull body 01 / plate 1, the width direction of the pull head is the same as the width direction of the pull body 01 / plate 1, and the thickness direction of the pull head is the same as the thickness direction of the pull body 01 / plate 1. "Front end" refers to the end of the two plates 1 that face each other after they are joined and interlocked along their length directions. Furthermore, the orientations or positional relationships indicated by "up," "down," "left," and "right" mentioned herein are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Please refer to Figure 3 and Figure 5 This utility model provides an embodiment of an interlocking zipper locking structure for locking two zipper heads together. It includes two plates 1, each of which includes a first plate 11 and a second plate 12 that are opposite to each other and spaced apart. Both plates 1 are also provided with an interlocking structure 3.

[0052] The interlocking structure 3 includes a connecting arm 31 and an interlocking member 32. The connecting arm 31 is located on the first end face of the second plate 12 facing away from the first plate 11 and extends partially from the front end of the second plate 12 to form an extension 311. The extension 311 is inclined away from the second plate 12 to leave a clearance space 33 between it and the plane where its first end face is located. The extension 311 is also provided with an interlocking member 32.

[0053] The two plates 1 are connected by interlocking parts 32, which can lock the two plates 1 together in opposite directions along the length of the pull head. In the interlocked state, the two interlocking parts 32 can also rotate relative to each other around the width of the pull head. By rotating, the protrusion 311 on one plate 1 can be pushed against the first end face of the second plate 12 on the other plate 1 through the clearance space 33, so that the planes where the two second plates 12 of the two plates 1 are located form an angle, thus maintaining the interlocking state of the two interlocking parts 32.

[0054] It should be noted that existing zipper pulls typically consist of a pull body 01 and a pull tab disposed on the pull body 01, wherein the pull body 01 includes an upper wing plate 011 and a lower wing plate 012 that are opposite to each other and spaced apart. The interlocking zipper pull locking structure of this application has three implementation methods in practical applications: as follows... Figure 8 As shown, in the first embodiment, the interlocking zipper locking structure of this application can be directly applied to interlocking zippers (containing two zippers), that is, the two plates 1 in the interlocking zipper locking structure are respectively set as the pull body 01 of the two zippers. That is, the first plate 11 and the second plate 12 in each plate 1 can be directly used as the upper wing plate 011 and the lower wing plate 012 of the pull body 01. Figure 3As shown, in the second embodiment, the first plate 11 and the second plate 12 in the interlocking zipper locking structure of this application are both configured as plate sleeve structures 2, which are respectively sleeved on the upper wing plate 011 and the lower wing plate 012 of the zipper body 01. In the third embodiment (not shown), the second plate 12 with an interlocking structure 3 in the interlocking zipper locking structure of this application is configured as a plate sleeve structure 2, which is sleeved on the lower wing plate 012 of the zipper body 01, and the first plate 11 directly serves as the upper wing plate 011 of the zipper body 01. It should be noted that the second and third embodiments can protect the zipper structure while achieving interlocking of the two zippers, thus preventing zipper wear.

[0055] Each plate 1 corresponds to an interlocking structure 3. The interlocking structure 3 includes a connecting arm 31 and an interlocking element 32. The connecting arm 31 is preferably integrally formed on the first end face of the second plate 12, and a portion of the connecting arm 31 extends from the front end of the second plate 12 to form a protrusion 311. The protrusion 311 is inclined away from the second plate 12 to leave a clearance space 33 between itself and the plane containing the first end face of the second plate 12. Thus, as Figure 7 As shown, after the two plates 1 are interlocked, that is, after the two zipper heads are interlocked, if the two zipper heads pass through the curved zipper, the clearance space 33 on one plate 1 (i.e., one zipper head) can provide a certain rotation space for the protrusion 311 on the other plate 1 (i.e., the other zipper head), so as to avoid the protrusions 311 of the two plates 1 interfering with each other and causing the two zipper heads to be unable to pass through the curved zipper smoothly.

[0056] Furthermore, the interlocking member 32 is provided at the protrusion 311 of the second plate 12, such that... Figure 5 and Figure 6 As shown, the interlocking process of the two zipper heads is as follows: the two plates 1 are joined together facing each other along the length of the zipper head, and then the interlocking parts 32 on them are connected, which can lock the two plates 1 together, thereby achieving interlocking of the two zipper heads. It should be noted that when the two plates 1 (i.e., the two zipper heads) are locked, the interlocking parts 32 on the two plates 1 can rotate relative to each other around the width of the zipper head. If the two zipper heads pass through a bent zipper, the interlocking parts 32 on the two plates 1 can rotate relative to each other, ensuring that the two plates 1 can rotate a certain angle with the two plates 1 during the bending process, and that the two interlocking parts 32 remain connected and do not disengage.

[0057] Therefore, the interlocking zipper locking structure provided in the above embodiments is applied to interlocking zippers, which can ensure that after the two zippers are interlocked, they can pass smoothly through the curved zipper while still maintaining the interlocked state, avoiding jamming and unlocking.

[0058] Regarding the first plate 11 and the second plate 12 in plate body 1, there are two arrangement methods. In specific embodiment one, as follows: Figure 5As shown, the first plate 11 and the second plate 12 are arranged from top to bottom. The first plate 11 is the upper wing plate 011 of the pull body 01 or is located on the upper wing plate 011 of the pull body 01, and the second plate 12 is the lower wing plate 012 of the pull body 01 or is located on the lower wing plate 011 of the pull body 01. In this arrangement, when the two zipper pulls pass through a curved zipper, the curved zipper protrudes upwards. The interlocking member 32 on one plate 1 rotates relative to the interlocking member 32 on the other plate 1 while maintaining a locked connection. Simultaneously, the protruding portion 311 on one plate 1 can tilt upwards to abut against the bottom surface of the second plate 12 on the other plate 1, thus ensuring that the two zipper pulls remain interlocked when passing through the curved zipper. Furthermore, the interlocking structure 3 is entirely located below the bottom surface of the second plate 12, concealing the interlocking structure 3 and preventing its exposure, thereby reducing the risk of theft of items inside the backpack or tent.

[0059] In the second specific embodiment, the first plate 11 and the second plate 12 are arranged from bottom to top. That is, the first plate 11 is the lower wing plate 012 of the pull body 01 or is provided on the lower wing plate 012 of the pull body 01, and the second plate 12 is the upper wing plate 011 of the pull body 01 or is provided on the upper wing plate 011 of the pull body 01. In this arrangement, when the two zipper heads pass through the curved zipper, the curved zipper is concave downwards. The interlocking member 32 on one plate 1 rotates relative to the interlocking member 32 on the other plate 1 and still maintains the connection and lock. At the same time, the protrusion 311 on one plate 1 can be tilted downwards to abut against the top surface of the second plate 12 on the other plate 1, thereby ensuring that the two zipper heads can still maintain the interlocking state when passing through the curved zipper.

[0060] It should be noted that in the two embodiments described above, the protrusion 311 on one plate 1 abuts against the end face of the second plate 12 on the other plate 1, which can realize the vertical limiting and locking of the two hooks and prevent the two hooks from breaking off vertically when passing through the bent zipper.

[0061] The following embodiments are all illustrated using the first plate 11 and the second plate 12 arranged from top to bottom.

[0062] Based on the above embodiments, as a further preferred embodiment, the end face of the protrusion 311 adjacent to the second plate 12 along the thickness direction of the pull head is provided as an inclined surface 312, the inclined surface 312 extends from the front end of the second plate 12 to the front end of the connecting arm 31 and gradually tilts away from the second plate 12.

[0063] When the two zipper pulls pass through the horizontal zipper, the second plates 12 of the two plates 1 are flush with the horizontal plane, and the protruding part 311 is set as an inclined surface 312 along the direction perpendicular to the horizontal plane and adjacent to the end face of the second plate 12. Figure 3As shown, specifically, the upper end face of the protrusion 311 is set as an inclined surface 312, so that the inclined surface 312 of the protrusion 311 on one plate 1 is placed directly below the second plate 12 on the other plate 1. In this way, when the two zipper heads pass through the bending zipper, after the protrusions 311 of both plates 1 are tilted upwards, the inclined surface 312 of the protrusion 311 on one plate 1 can fit more closely with the bottom end face of the second plate 12 on the other plate 1, avoiding insufficient contact surface 121 between the protrusions 311 of the two plates 1, which would cause them to separate.

[0064] Based on the above embodiments, as a further preferred embodiment, the front end face of the connecting arm 31 is set as an arc surface, and the arc surface connects the inclined surface 312 and the protrusion 311 along the thickness direction of the pull head away from the end face of the second plate 12.

[0065] like Figure 3 As shown, specifically, the upper and lower surfaces of the connecting arm 31 are connected by a rounded transition. The rounded transition avoids sharp corners, thereby minimizing scratches on the items inside the bag.

[0066] Based on the above embodiments, as a further preferred embodiment, the interlocking member 32 is provided on one side of the protrusion 311 along the width direction of the pull head.

[0067] like Figure 3 and 8 As shown, specifically, the interlocking member 32 is located on the left (or right) side of the protrusion 311, which can make reasonable use of the remaining positions of the protrusion 311 except for the inclined surface 312, and avoid the interlocking member 32 interfering with the inclined surface 312 of the protrusion 311 on one plate 1 and the second plate 12 on another plate 1.

[0068] Based on the above embodiments, as a further preferred embodiment, the interlocking component 32 is configured as a hook block, and the hook block has an interlocking arc surface 321 on one side away from the front end of the connecting arm 31 along the length direction of the pull head. The interlocking arc surface 321 extends from one end face of the protrusion 311 to the other end face along the thickness direction of the pull head.

[0069] like Figure 3 and 8As shown, specifically, the hook head extends along the width direction of the zipper pull to form a hook head of a certain thickness. An interlocking arc surface 321 is provided on the rear side of the hook head away from the front end of the connecting arm 31, and the interlocking arc surface 321 extends from one end face of the protrusion 311 to its other end face along the thickness direction of the zipper pull. Thus, the interlocking arc surfaces 321 of the two protrusions 311 contact each other, allowing the two hook blocks to engage, achieving upper limit locking of the two zipper pulls in the horizontal direction. Furthermore, when the two hook heads pass through a bent zipper, the two hook blocks can rotate relative to each other to ensure that their interlocking arc surfaces 321 remain in contact, thus ensuring that the two zipper pulls maintain their interlocked state. In addition, using two matching hook heads to achieve interlocking of the two zipper pulls facilitates quick and easy assembly and disassembly of the two zipper pulls.

[0070] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 , Figure 4 and Figure 6 The hook block has a hook block arc surface 322 on the side away from the connecting arm 31 along the width direction of the pull head. The hook block arc surface 322 extends from the front edge of the connecting arm 31 to the side of the interlocking arc surface 321 away from the connecting arm 31. In this way, during the process of the two pull heads being assembled and interlocked along the length direction of the pull heads, the hook block arc surface 322 on one plate 1 will make misaligned contact with the hook block arc surface 322 on the other plate 1. When the two plate bodies 1 are assembled together, the hook block arc surfaces 322 on the two plate bodies 1 will be misaligned and inserted behind the interlocking arc surfaces 321 of the two hook heads, so as to achieve the purpose of mutual contact and interlocking of the interlocking arc surfaces 321 of the two hook heads. Thus, during the process of the two pull heads being assembled and interlocked, the hook block arc surfaces 322 of the two hook blocks can play a positioning and guiding role, assisting the alignment of the interlocking arc surfaces 321 of the two hook blocks, which can improve the convenience and accuracy of the interlocking of the two pull heads.

[0071] Based on the above embodiments, as a further preferred option, please refer to... Figure 3 , Figure 8 and Figure 10 A connecting post 4 connects the first plate 11 and the second plate 12. The front ends of the first plate 11, the second plate 12, and the connecting post 4 are located on the same vertical plane. This vertical plane can serve as the front contact surface 125 of the zipper pull. Since the front contact surfaces 125 of the two zipper pulls are both vertical, when the two zipper pulls are interlocked, if they pass through a horizontal zipper, the front contact surfaces 125 of the two zipper pulls will be in complete contact. If they pass through a curved zipper, the front ends of the two zipper pulls will be raised, which can also maximize the contact between the front contact surfaces 125 of the two zipper pulls. This reduces the gaps in the interlocked state of the two zipper pulls, prevents rainwater, dust, and other impurities from entering during daily use, and improves the user experience.

[0072] Based on the above embodiments, as a further preferred embodiment, the second plate 12 is located below the first plate 11, and the front end of the second plate 12 is symmetrically provided with notches 124 on both sides along the width direction of the pull head.

[0073] like Figure 9 As shown, specifically, the front end of the second plate 12 serves as a contact surface 121 for contacting the front end of another second plate 12. Both sides of the second plate 12 have vertical surfaces 122 and convex surfaces 123 arranged from front to back. The vertical surfaces 122 are adjacent to and perpendicular to the contact surfaces 121. The contact surfaces 121 and vertical surfaces 122 are connected with rounded corners. The maximum distance from the convex surface 123 along the width direction to the center line of the second plate 12 is greater than the maximum distance from the vertical surface 122 along the width direction to the center line of the second plate 12. The vertical surfaces 122 and convex surfaces 123 are connected by an arc surface. Thus, on both sides of the second plate 12, the vertical surfaces 122 and the arc surfaces can form inward notches 124, causing the front end of the second plate 12 of the zipper pull to form an inward-curving structure. This reduces the contact between the zipper teeth and the front end of the second plate 12 of the zipper pull when the zipper pull slides on the teeth of a horizontal or curved zipper, thereby preventing scratches on the teeth.

[0074] Please refer to Figure 8 and Figure 10 The present invention can provide a first embodiment of an interlocking zipper head, which includes the interlocking zipper head locking structure disclosed in the above embodiment. The two plates 1 are the two pull bodies 01 of the interlocking zipper head. Both pull bodies 01 are provided with an interlocking structure 3. The two interlocking structures 3 can interlock the two pull bodies 01 together, thereby realizing the interlocking and locking of the two zipper heads together.

[0075] Please refer to Figure 3 , Figure 5 and Figure 6 This utility model can also provide a second embodiment of the interlocking zipper pull, which includes two pull bodies 01 and the interlocking zipper pull locking structure disclosed in the above embodiment. Each pull body 01 includes an upper wing plate 011 and a lower wing plate 012. The upper wing plate 011 and the lower wing plate 012 are respectively fitted with a first plate 11 and a second plate 12, both of which are plate sleeve structures 2 in the plate body 1. Thus, the interlocking zipper pull locking structure can lock the two zipper pulls while protecting the zipper pull structure and preventing wear.

[0076] This utility model can also provide a third embodiment of an interlocking zipper pull, which includes two pull bodies 01, each of which includes an upper wing plate 011 and a lower wing plate 012. In the interlocking zipper pull locking structure disclosed in the above embodiment, the second plates 12 of the two plates 1 are both set as plate sleeve structures 2, and are respectively sleeved on the lower wing plates 012 of the two pull bodies 01. The first plates 11 of the two plates 1 are respectively set as the upper wing plates 011 of the two pull bodies 01, that is, the first plates 11 directly serve as the upper wing plates 011. In this way, while locking the two zipper pulls, the zipper pull structure can also be protected to avoid wear on the lower wing plates of the zipper pull.

[0077] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0078] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0079] The foregoing has provided a detailed description of the interlocking zipper pull and its locking structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
