Technical Field

[0002] This invention relates to the field of fastener technology, and more particularly to a magnetic fastener. Background Technology

[0003] With the continuous development of the economy and the continuous progress of science and technology, people's lives are provided with an extremely rich variety of material consumer goods, and infant and toddler vehicles are one of these many material consumer goods.

[0004] As we all know, braided straps are indispensable in infant and toddler vehicles; and fasteners are essential for the easy assembly and disassembly of different braided straps.

[0005] Currently, traditional fasteners consist of a male buckle, a female buckle, and a button. The male and female buckles are locked together, and the button is used to release them.

[0006] However, traditional fasteners suffer from drawbacks such as cumbersome fastening operations and complex structures.

[0007] Therefore, there is an urgent need for a magnetic fastener that is easy to operate and has a compact structure to overcome the above-mentioned defects. Summary of the Invention

[0011] Preferably, the locking part includes a spring arm and a lock head for locking with the locking structure. The lock head is connected to the spring arm, and the spring arm always has a tendency to drive the lock head to lock with the locking structure. During the insertion process, the pushing structure pushes the lock head to drive the spring arm to produce elastic deformation, causing the lock head to slide to the position where it locks with the locking structure. The release operation selectively drives the spring arm to make elastic deformation, causing the lock head to disengage from the locking structure.

[0012] Preferably, the release mechanism pushes the spring arm along the direction parallel to the insertion direction to produce elastic deformation along the direction intersecting with the insertion direction, thereby causing the lock head to disengage from the locking structure.

[0013] Preferably, the release mechanism has a push-up ramp that is inclined relative to the insertion direction, and the release mechanism pushes the spring arm to generate elastic deformation by the push-up ramp.

[0014] Preferably, the lock head is arranged in a ring-shaped locking structure, and the push-up ramp slopes from the inside to the outside in a direction away from the push-up structure. The release mechanism is elastically deformed by pushing the spring arm through the push-up ramp.

[0015] Preferably, there are at least two spring arms arranged in a mating and interlocking configuration, and each spring arm is connected to a lock head.

[0016] Preferably, the release mechanism extends outward along the insertion direction to form a spreading leg, and a pushing slope is formed on the spreading leg.

[0017] Preferably, the end of the spring arm that is connected to the lock cylinder has a push-received ramp that matches the push ramp. The release mechanism pushes the spring arm to produce elastic deformation by the cooperation of the push ramp and the push-received ramp.

[0018] Preferably, the end of the spring arm that is connected to the lock head has a groove, the extension leg is placed in the groove, the push-receiving slope is formed on the groove wall surface, and the pushing slope is formed on the end face of the extension leg.

[0019] Preferably, the pushing ramp of the spread leg engages with the pushing end of the spring arm away from the lock head.

[0020] Preferably, the magnetic fastener of the present invention further includes an elastic element that provides a reset force for the release operation element.

[0021] Preferably, the end of the push-pull structure has a first inclined structure that is inclined relative to the insertion direction, and the lock head has a second inclined structure that matches the first inclined structure; during the insertion process, the push-pull structure passes over the lock head and slides to the position where the locking structure and the lock head are locked by the push of the first inclined structure against the second inclined structure.

[0022] Preferably, the lock head has a hook-shaped structure, and the matching lock structure is a hook groove.

[0023] Preferably, the male buckle has a first insert cavity, the female buckle has a second insert cavity, the first magnetic attraction structure is inserted into the first insert cavity, and the second magnetic attraction structure is inserted into the second insert cavity.

[0024] Preferably, the first embedding cavity is aligned with the second embedding cavity along the insertion direction.

[0025] Preferably, the first or second insert cavity is formed within the mating locking portion.

[0026] Preferably, at least one of the first magnetic attraction structure and the second magnetic attraction structure is a magnet.

[0027] Preferably, the release mechanism is a round or square knob.

[0028] Preferably, the magnetic fastener of the present invention further includes an outer cover, a male fastener is placed inside the outer cover, and an unlocking operation member is movably inserted through the outer cover in the interlocking direction.

[0029] Preferably, the female buckle and the outer cover each have an assembly end for assembling the braided strip, and the assembly end has a through hole for the braided strip to pass through.

[0030] Preferably, the outer cover has a through hole at one end in the interlocking direction for the locking mechanism to pass through, and an interlocking hole at the other end in the interlocking direction for the interlocking locking part to interlock.

[0031] Preferably, the outer cover has protruding ribs located on the side wall of the outer cover.

[0032] Preferably, the mating locking part is a cylindrical structure, and the male and female buckles can selectively rotate around the mating locking part. The female buckle has two assembly ends arranged opposite to each other, and the two oppositely arranged assembly ends are used by rotating between the male and female buckles.

[0033] Compared with the prior art, the magnetic buckle of the present invention achieves the locking of the male buckle and the female buckle by locking the locking part and the mating locking part. Then, the first magnetic attraction structure provided on the male buckle and the second magnetic attraction structure provided on the female buckle are magnetically attracted to each other, so that the male buckle and the female buckle remain in the mating state. Under the mutual repulsion of the first magnetic attraction structure and the second magnetic attraction structure, the locking part and the mating locking part remain in the mutual contact state. Therefore, the magnetic buckle of the present invention makes the fastening between the male buckle and the female buckle more reliable. At the same time, by means of the mutual magnetic attraction of the first magnetic attraction structure and the second magnetic attraction structure, even if the user or child accidentally touches the release mechanism and the locking part and the mating locking part are released, the male buckle and the female buckle will still remain in the mating state and will not automatically disengage from each other. Therefore, the safety is better and it can also prevent the male buckle and the female buckle from falling off everywhere due to the release of the locking part and the mating locking part. Alternatively, by means of mutual repulsion between the first magnetic attraction structure and the second magnetic attraction structure, after the male and female buckles are released, the male and female buckles will automatically separate, thus facilitating the release operation of the male and female buckles; in addition, the magnetic buckle of the present invention also has the advantage of a compact structure.

[0047] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0048] Please see Figures 1 to 4 The magnetic fastener 100 of the first embodiment includes a male fastener 1, a female fastener 2, a release operation member 3, and a first magnetic attraction structure 4 and a second magnetic attraction structure 5 that are magnetically attracted to each other. The male fastener 1 has a locking part 1a, and the female fastener 2 has a mating locking part 2a for engaging with the locking part 1a. The first magnetic attraction structure 4 is provided on the male fastener 1, and the second magnetic attraction structure 5 is provided on the female fastener 2. The male fastener 1 and the female fastener 2 are mated together in a direction close to each other, thereby locking the locking part 1a and the mating locking part 2a. The first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnetically attracted to each other during the mating process, thereby making the fastening of the male fastener 1 and the female fastener 2 faster. The release operation member 3 is movably provided on the male fastener 1. When the release operation member 3 selectively releases the locking part 1a and the mating locking part 2a to allow the male fastener 1 and the female fastener 2 to be pulled out from each other, the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnetically attracted to each other, keeping the male fastener 1 and the female fastener 2 in a mated state. Of course, in other embodiments, the first magnetic attraction structure 4 provided on the male buckle 1 and the second magnetic attraction structure 5 provided on the female buckle 2 can also magnetically repel each other. This mutual magnetic repulsion between the first magnetic attraction structure 4 and the second magnetic attraction structure 5 keeps the locking part 1a and the mating locking part 2a in a mutually abutting state after fastening, thus making the fastening more reliable. Therefore, this is not limited to the examples described above. Specifically, in this embodiment, the magnetic buckle 100 of this embodiment also includes an outer cover 6, with the male buckle 1 housed within the outer cover 6. The release operation member 3 is positioned along the mating direction (e.g., ...). Figure 4The locking part 1a is movably mounted on the outer cover 6 in the vertical direction shown. Preferably, the unlocking operation part 3 is a circular button, so that the user can release the locking part 1a and the mating locking part 2a by pressing the unlocking operation part 3; the outer cover 6 at one end in the mating direction (as shown in the vertical direction) is movably mounted on the outer cover 6. Figure 4 The upper end of the outer cover 6 has a through hole 61 for the release locking operation member 3 to pass through. The other end of the outer cover 6 in the interlocking direction (e.g.) Figure 4 The lower end of the outer cover 6 has an insertion hole 62 for the mating locking part 2a to be inserted. The outer cover 6 allows the male buckle 1 and female buckle 2 to move more smoothly during operation, while also preventing dust accumulation and reducing wear caused by external factors. This extends the service life of the magnetic buckle 100 in this embodiment and also makes it more aesthetically pleasing. It is understood that in other embodiments, the mating locking part 2a may be formed on the male buckle 1, and the locking part 1a may be formed on the female buckle 2. When the locking part 1a is formed on the female buckle 2, the unlocking operation member 3 is correspondingly provided on the female buckle 2. Furthermore, the outer cover 6 can be removed according to actual needs, and is not limited to the examples described above. More specifically, as follows: Combination Figure 5 and Figure 6 The locking part 1a is an elastic structure, and the mating locking part 2a has a pushing structure 21 and a locking structure 22. During the mating process, the pushing structure 21 pushes the locking part 1a, causing the locking part 1a to undergo elastic deformation, thereby causing the locking part 1a to slide to the position where it is locked with the locking structure 22, as shown in the figure. Figure 4 As shown; the release mechanism 3 selectively drives the locking part 1a to elastically deform and disengage from the locking structure 22. Therefore, the push structure 21 enables the locking structure 22 to lock with the locking part 1a more quickly and smoothly. Specifically, in this embodiment, the locking part 1a includes a spring arm 11 and a lock head 12 for locking with the locking structure 22. The lock head 12 is connected to the spring arm 11. Preferably, the spring arm 11 and the lock head 12 together form an integral structure, so that the lock head 12 is suspended in the middle of the male buckle 1 by means of the spring arm 11, as shown in the figure. Figure 3As shown, this allows the spring arm 11 to reliably drive the lock head 12 to move. The spring arm 11 always has a tendency to drive the lock head 12 to lock with the locking structure 22; therefore, during the insertion process, the pushing structure 21 pushes the lock head 12 to drive the spring arm 11 to produce elastic deformation, thereby causing the lock head 12 to slide to the position to lock with the locking structure 22, realizing the purpose of automatic locking of the male latch 1 and the female latch 2 during the insertion process; the release operation member 3 selectively drives the spring arm 11 to make elastic deformation, thereby causing the lock head 12 to disengage from the locking with the locking structure 22. Preferably, the release operation member 3 pushes the spring arm 11 along the direction parallel to the insertion direction, causing the spring arm 11 to produce elastic deformation along the direction intersecting with the insertion direction, thereby causing the lock head 12 to disengage from the locking with the locking structure 22, so that the release process between the lock head 12 and the locking structure 22 is simple. For example, in this embodiment, there are two spring arms 11 arranged in a clamping and interlocking locking configuration 2a. Each spring arm 11 is connected to a lock head 12, so that the lock head 12 is arranged to encircle the locking structure 22, thereby making the lock head 12 more reliably locked with the locking structure 22, and thus making the engagement of the male buckle 1 and the female buckle 2 more stable and reliable. Of course, in other embodiments, the number of spring arms 11 can be three, four or five, so it is not limited to this. Preferably, the lock head 12 is a hook-shaped structure, and the locking structure 22 is a hook groove, so that the magnetic buckle 100 of this embodiment can be more tightly engaged and less likely to detach by the cooperation of the hook-shaped structure and the hook groove. At the same time, the male buckle 1 is a hollow structure, and the middle part of the male buckle 1 has a horizontally placed intermediate support arm 14. The intermediate support arm 14 is located between the two spring arms 11 and connected to the corresponding side walls of the male buckle 1 to increase the strength of the male buckle 1.

[0049] Please see Figures 3 to 6 The ends of the jacking structure 21 have a relative interlocking direction (e.g., Figure 4 The lock head 12 has a first inclined structure 211 (shown in the vertical direction) that is inclined, and a second inclined structure 121 that matches the first inclined structure 211. During the insertion process, the first inclined structure 211 pushes the second inclined structure 121, allowing the pushing structure 21 to easily pass over the lock head 12 and slide to the position where the locking structure 22 and the lock head 12 are locked, thereby facilitating the locking of the male buckle 1 and the female buckle 2.

[0050] Please see Figures 3 to 6The release mechanism 3 has a push-up slope 31 inclined relative to the insertion direction. The release mechanism 3 uses the push-up slope 31 to push the spring arm 11 to generate elastic deformation, thereby causing the lock head 12 to disengage from the locking structure 22 and release the lock. Since the lock head 12 is arranged to encircle the locking structure 22, the push-up slope 31 is inclined from the inside to the outside in a direction away from the push-up structure 21. The release mechanism 3 uses the push-up slope 31 to push the spring arm 11 to generate elastic deformation, thereby enabling the spring arm 11 to drive the lock head 12 outward to disengage from the locking structure 22. Of course, in other embodiments, the spring arm 11 can also drive the lock head 12 inward to disengage from the locking structure 22, so it is not limited to this. For example, in this embodiment, the release mechanism 3 extends outward along a direction parallel to the insertion direction to form a spreading leg 32, and the push-up slope 31 is formed on the spreading leg 32. The end of the spring arm 11 that connects to the lock cylinder 12 has a push-receiving slope 111 that matches the push-up slope 31. The release operation member 3 pushes the spring arm 11 to generate elastic deformation by the cooperation of the push-up slope 31 and the push-receiving slope 111, so that the lock cylinder 12 disengages from the locking structure 21. Preferably, the end of the spring arm 11 that connects to the lock cylinder 12 has a groove 112, and the expansion leg 32 extends into the groove 112. The push-receiving slope 111 is formed on the groove wall of the groove 112, and the push-up slope 31 is formed on the end face of the expansion leg 32. This makes the structure of the release operation member 3 pushing the spring arm 11 to generate elastic deformation simpler. The expansion leg 32 acts directly on the groove 112 at the end that connects to the lock cylinder 12, which makes the elastic deformation of the spring arm 11 faster and makes the lock cylinder 12 disengage from the locking structure 22 faster. Therefore, it is not limited to this.

[0051] Please see Figure 3 , Figure 4 and Figure 6The male buckle 1 has a first embedding cavity 13, and the female buckle 2 has a second embedding cavity 23. A first magnetic attraction structure 4 is embedded in the first embedding cavity 13, and a second magnetic attraction structure 5 is embedded in the second embedding cavity 23, so that the first magnetic attraction structure 4 is hidden in the male buckle 1, and the second magnetic attraction structure 5 is hidden in the female buckle 2. Specifically, the first embedding cavity 13 is aligned with the second embedding cavity 23 along the insertion direction, so that the magnetic force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5 is maximized, thereby making the insertion between the male buckle 1 and the female buckle 2 faster, and at the same time maintaining a maximum magnetic attraction force between the male buckle 1 and the female buckle 2 after insertion, effectively preventing the male buckle 1 and the female buckle 2 from accidentally separating. For example, the second insert cavity 23 is formed within the mating locking portion 2a, and the first insert cavity 13 is formed at the middle of the male buckle 1, specifically at the middle of the intermediate support arm 14, making reasonable use of space and saving materials in the magnetic buckle 100 of the present invention. Meanwhile, both the first magnetic attraction structure 4 and the second magnetic attraction structure 5 are magnets. Of course, in other embodiments, one of the first magnetic attraction structure 4 and the second magnetic attraction structure 5 is a magnet, and the other is a metal structure, so it is not limited to this. Preferably, the thickness of the first magnetic attraction structure 4 is in the range of 3.0 to 5.5 mm, more preferably 3.0, 3.8, 4.5, 5.0, or 5.5 mm. It is noteworthy that when the mating locking portion 2a is formed on the male buckle 1, the first insert cavity 13 is formed within the mating locking portion 2a.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the female buckle 2 and the outer cover 6 each have an assembly end for assembling the braided strap. Preferably, the female buckle 2 has two assembly ends arranged opposite to each other, while the outer cover 6 has one assembly end that is always arranged opposite to either assembly end on the female buckle 2, to facilitate the assembly of the braided strap. For example, the assembly ends of the female buckle 2 and the outer cover 6 have through holes 24 and 63 for the braided strap to pass through. The female buckle 2 can be fixed to the first fabric surface (not shown) by means of its two assembly ends and the braided strap passing through the two assembly ends, while the male buckle 1 can be fixed to the braided strap connected to the second fabric surface (not shown) by means of the assembly end of the outer cover 6, thereby achieving a detachable connection between the first fabric surface and the second fabric surface. In other embodiments, the mating locking part 2a is a cylindrical structure, allowing the male buckle 1 and the female buckle 2 to selectively rotate around the mating locking part 2a. This makes the operation of the male buckle 1 and the female buckle 2 more flexible, and allows either assembly end on the female buckle 2 to be used with the assembly end on the outer cover 6 after rotation. When one of the assembly ends on the female buckle 2 is damaged, rotating the female buckle 2 allows the other assembly end to be used together with the assembly end on the outer cover 6, making the magnetic fastener 100 of the present invention durable.

[0053] Please see Figures 7 to 10The second embodiment shown is basically the same as the first embodiment in terms of the magnetic buckle 100a, except that: First, in this embodiment, the outer cover 6 is provided with a rib 64 protruding on it. The rib 64 is located on the side wall of the outer cover 6. Preferably, the rib 64 is located on the opposite side walls of the outer cover 6. The rib 64 increases the frictional resistance, which facilitates the operator to operate the magnetic buckle 100a. In the first embodiment, the outer cover 6 is not provided with a rib 64 protruding on it.

[0054] Secondly, in this embodiment, the pushing slope 31 of the spreading leg 32 engages with the end of the spring arm 11 away from the lock head 12. Force is directly applied to the end of the spring arm 11 away from the lock head 12 by the pushing slope 31 of the spreading leg 32. That is, the spreading leg 32 is located between the spring arm 11 and the intermediate support arm 14. Therefore, in this embodiment, the spring arm 11 does not have a pushing slope 111 or a groove 112 that engages with the pushing slope 31. Since the spreading legs 32 in this embodiment are arranged in pairs and spaced apart, the intermediate support arm 14 is engaged within the gap between the paired spreading legs 32.

[0055] Third, since the pushing slope 3 of the spreading leg 32 in this embodiment directly applies force to the end of the spring arm 11 away from the lock head 12, in order to make the release operation member 3 reset more reliably, the magnetic buckle 100a in this embodiment also includes an elastic member 7 that provides elastic force for the reset of the release operation member 3. The elastic member 7 is preferably a spring, but it can be designed as an elastic plastic structure according to actual needs. The elastic member 7 abuts against the release operation member 3 and the male buckle 1, but is not limited to this. In the first embodiment, since the pushing slope 31 of the spreading leg 32 applies force to the end of the spring arm 11 connected to the lock head 12, the reset of the release operation member 3 is achieved by the spring arm 11.

[0056] Fourth, in this embodiment, the thickness of the first magnetic structure 4 is 5.0 mm, while in the first embodiment, the thickness of the first magnetic structure 4 is 3.8 mm.

[0057] Apart from the differences mentioned above, everything else is the same as in the first embodiment, so it will not be repeated here.

[0058] Please see Figures 11 to 13 The third embodiment shown has a magnetic buckle 100b with a structure that is basically the same as the magnetic buckle 100a in the second embodiment, with the following differences: First, in this embodiment, the release operation component 3 is a square button; while in the second embodiment, the release operation component 3 is a round button.

[0059] Secondly, in this embodiment, the outer cover 6 is not provided with ribs 64; while in the second embodiment, the outer cover 6 is provided with ribs 64.

[0060] Third, in this embodiment, the elastic member 7 abuts against the release operation member 3 and the male buckle 1, and is offset from the first embedded cavity 13; while in the second embodiment, the elastic member 7 abuts against the release operation member 3 and the male buckle, and is directly opposite the first embedded cavity 13.

[0061] Apart from the differences mentioned above, everything else is the same as in the second embodiment, so it will not be repeated here.

[0062] Combination Figures 1 to 6 The working principle of the magnetic buckle 100 of the first embodiment of the present invention will be explained as follows: When the magnetic buckle 100 of this embodiment is to be switched from the locked state to the unlocked state, the unlocking operation member 3 is pressed down. The spreading leg 32 below the unlocking operation member 3 contacts the groove 112 of the spring arm 11 and pushes the groove 112. Thus, by the cooperation of the pushing inclined surface 31 on the spreading leg 32 and the pushing inclined surface 111 on the groove 112, the spring arm 11 is pushed outward, which drives the lock head 12 connected to the spring arm 11 to be pushed outward together, thereby disengaging from the locking structure 22 on the mating locking part 2a, so that the male buckle 1 and the female buckle 2 are in the unlocked state. At the same time, the female buckle 2 and the male buckle 1 are pulled apart in opposite directions of mating, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, so that the male buckle 1 and the female buckle 2 are disengaged from each other. When engaging male buckle 1 and female buckle 2, first align the mating locking part 2a with the mating hole 62 in the outer cover 6; then bring male buckle 1 and female buckle 2 closer together, and under the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the pushing structure 21 on the mating locking part 2a easily passes over the lock head 12, thereby locking the locking structure 22 with the lock head 12, realizing the locking of male buckle 1 and female buckle 2.

[0063] Combination Figures 7 to 10The working principle of the magnetic buckle in the second embodiment is explained as follows: When the magnetic buckle 100a of this embodiment is to be switched from the locked state to the unlocked state, the unlocking operation member 3 is pressed down so that the elastic member 7 is in a compressed state. The pushing slope 31 of the spreading leg 32 below the unlocking operation member 3 directly applies force to the end of the spring arm 11 away from the lock head 12, so that the spring arm 11 is spread outward and drives the lock head 12 connected to the spring arm 11 to be spread outward together, thereby disengaging from the locking structure 22 on the mating locking part 2a, so that the male buckle 1 and the female buckle 2 are in the unlocked state. At the same time, the female buckle 2 and the male buckle 1 are pulled apart in the opposite direction of mating, so that the pulling force is greater than the mutual magnetic attraction force between the first magnetic attraction structure 4 and the second magnetic attraction structure 5, so that the male buckle 1 and the female buckle 2 are disengaged from each other. At this time, the reset of the unlocking operation member 3 is achieved by the elastic member 7. When engaging male buckle 1 and female buckle 2, first align the mating locking part 2a with the mating hole 62 in the outer cover 6; then bring male buckle 1 and female buckle 2 closer together, and under the mutual magnetic attraction of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the pushing structure 21 on the mating locking part 2a easily passes over the lock head 12, thereby locking the locking structure 22 with the lock head 12, realizing the locking of male buckle 1 and female buckle 2. (See attached diagram) Figure 9 Since the working principle of the magnetic buckle 100b in the third embodiment is the same as that of the magnetic buckle 100a in the second embodiment, it will not be described again here.

[0064] Compared with the prior art, the magnetic buckles 100, 100a, and 100b of the present invention achieve the locking of the male buckle 1 and the female buckle 2 by locking the locking part 1a and the mating locking part 2a. Furthermore, the first magnetic attraction structure 4 on the male buckle 1 and the second magnetic attraction structure 5 on the female buckle 2 magnetically attract each other, maintaining the male buckle 1 and the female buckle 2 in a mating state. Under the mutual repulsion of the first magnetic attraction structure 4 and the second magnetic attraction structure 5, the locking part 1a and the mating locking part 2a remain in a state of mutual contact. Therefore, the magnetic... The magnetic fastener 100 makes the engagement between the male buckle 1 and the female buckle 2 more reliable. Simultaneously, due to the mutual magnetic attraction of the first magnetic structure 4 and the second magnetic structure 5, even if the user or a child accidentally triggers the release mechanism, causing the locking part 1a and the mating locking part 2a to be released, the male buckle 1 and the female buckle 2 remain in the mating state and will not automatically disengage. Therefore, safety is improved, and the possibility of loss due to the male buckle 1 and the female buckle 2 falling off due to the release of the locking part 1a and the mating locking part 2a is prevented. Alternatively, due to the mutual repulsion of the first magnetic structure 4 and the second magnetic structure 5, the male buckle 1 and the female buckle 2 automatically separate after release, facilitating the release operation of the male buckle 1 and the female buckle 2. Furthermore, the magnetic fasteners 100, 100a, and 100b of the present invention also have the advantage of a compact structure.

[0065] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
