Description

[Technical Field]

[0001] The present invention relates to an optical accessory adapter ring, and more particularly to a collapsible optical accessory adapter ring that reduces the thickness of the frame and can be broken by external force. [Background technology]

[0002] With the rapid development of digital and optical technologies, various digital products are constantly improving in both functionality and performance, and are becoming more and more popular as prices fall. Generally, when users take photos with a camera, they usually attach filters with different effects (e.g., soft focus filters, star effect filters, polarizing filters, ND filters, color filters, etc.) to the camera lens to achieve various different image effects. Users may also attach separate protective lenses to the camera lens or filters to protect the camera lens or the filters.

[0003] With the advancement of various image processing software, many of the filters mentioned above are gradually being replaced by powerful digital technology. However, polarizing filters, ND filters, and protective filters remain extremely difficult to replace. As the name suggests, ND filters reduce light transmittance and are generally categorized into several different standards depending on their light transmittance. Consumers can attach one or more ND filters of different standards to their lenses depending on their actual shooting needs to appropriately reduce the amount of light passing through the lens and enable shooting in environments with strong light sources. Polarizing filters are manufactured based on the principle of light polarization, and by rotating the polarizing filter, the amount of light passing through at a specific polarization angle can be adjusted. By attaching a polarizing filter to a lens and adjusting the angle appropriately, consumers can effectively eliminate reflected light from object surfaces (e.g., the surface of water, shop window glass, or the surface of plant leaves) to achieve ideal shooting results. Protective filters are used to protect camera lenses, polarizing filters, or ND filters, preventing scratches from external dust (e.g., quartz sand) and damage from impacts.

[0004] It should be noted that different camera lenses, filters, and protection filters may have different apertures due to differences in brand and design standards. To connect optical accessories with different apertures, adapter rings are usually used as a connection medium, so users do not need to purchase corresponding filters or protection filters separately for their camera lenses, reducing the purchase cost of photographic equipment and the storage space it occupies.

[0005] However, conventional adapter rings often suffer from improper fitting when connected to filters or protective filters with external threads or screw threads. For example, due to the low production rate of internal threads in adapter rings, jamming can occur when threading a filter or protective filter onto the adapter ring. In this case, when attempting to break the adapter ring with external force, it is difficult to accurately apply the appropriate force due to the material and thickness (approximately 2 mm) of the adapter ring, and this can even indirectly damage the filter or protective filter. Therefore, effectively solving the above problems and improving the convenience of breaking the adapter ring are important objectives of the present invention. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to solve the above-mentioned problems, the inventors have repeatedly researched and tested, and finally developed the collapsible optical accessory adapter ring of the present invention. It is hoped that the present invention will effectively solve the problems of the past and provide a better user experience for businesses and / or users. [Means for solving the problem]

[0026] The present invention relates to a collapsible optical accessory adapter ring, which is applied to a camera C. In a first embodiment, referring to FIG. 1, a collapsible optical accessory adapter ring A is used to connect a first optical accessory L and a second optical accessory F having different apertures. Specifically, referring to FIG. 2, the collapsible optical accessory adapter ring A includes at least one frame 1. The frame 1 is made of, but not limited to, a metal material (e.g., aluminum alloy) or plastic steel. The frame 1 is generally hollow and annular. For ease of explanation, the lower left of FIG. 2 refers to the front direction of the optical element, the upper right of FIG. 2 refers to the rear direction of the optical element, the upper side of FIG. 2 refers to the top direction of the optical element, and the lower side of FIG. 2 refers to the bottom direction of the optical element. Furthermore, the embodiment of the collapsible optical accessory adapter ring A of the present invention is not limited to that shown in the diagram of the present invention. Manufacturers can customize the external shape of the collapsible optical accessory adapter ring A according to product requirements. Therefore, if the collapsible optical accessory adapter ring A has the basic structure and effects described later in this invention, it is a collapsible optical accessory adapter ring A that is protected by the present invention.

[0027] 1 to 3B, when viewed from the side, the frame 1 has opposite ends with different outer diameters, and is divided into a first adapter end D1 and a second adapter end D2. The first adapter end D1 is located at one end (e.g., the rear end) of the frame 1 and is adapted to a first diameter associated with a first optical accessory L. The first adapter end D1 has a first connector 11 (e.g., an external thread) on its outer wall surface, which is connected to the first optical accessory L (e.g., various lenses such as wide-angle lenses, telephoto lenses, focus lenses, and zoom lenses, or various functional lenses such as protective filters, polarizing filters, and filters). The second adapter end D2 is located at the other end (e.g., the front end) of the frame 1 and is adapted to a second diameter associated with a second optical accessory F. The second adapter end D2 has a second connector 13 (e.g., an internal thread) on its inner wall surface, which is connected to the second optical accessory F via the second connector 13. In the first embodiment, the inner diameter of the second adapter end D2 may be larger than the outer diameter of the first adapter end D1, and the second diameter may be larger than the first diameter, but is not limited thereto. In other embodiments of the present invention, the first connecting portion 11 and the second connecting portion 13 may adopt other fastening structures other than screws according to the actual needs of the product.

[0028] See FIGS. 2 to 6. In a first embodiment, the frame 1 is provided with a plurality of force application portions 15 and a plurality of crushing portions 17. The force application portions 15 extend outward from the outer wall surface of the frame 1. As shown in FIG. 4, the force application portions 15 located at the upper part of the frame 1 protrude upward, while the force application portions 15 located at the lower part of the frame 1 protrude downward. Each force application portion 15 is provided with a through-hole 150, so that a user can apply force to the force application portion 15 by pinching the force application portion 15 with their hands or by inserting a removal tool (e.g., a hairpin, a key, a bamboo skewer, etc.) into the through-hole 150. In the first embodiment, the force application portions 15 are integrally molded with the frame 1, but this is not limiting. In other embodiments of the present invention, the force application portions 15 can be fixed to the frame 1 as independent parts by welding, adhesive bonding, riveting, fitting, screwing, or other methods. If a user applies force to the force application portion 15 and the crushing portion 17 can be deformed or torn as described below, it is the force application portion 15 referred to in the present invention. Furthermore, the size and shape of the through-hole 150 can be adjusted according to the actual needs of the product, and if multiple force application portions 15 are provided on the frame 1, the shapes of the through-holes 150 provided in each force application portion 15 can be the same or different, or even no through-hole 150 can be provided. The user can apply force by directly pinching the force application portion 15 with their fingers, or by clamping the force application portion 15 with another removal tool (e.g., a wrench).

[0029] 2 to 6, the crushed portion 17 is located on the frame 1, and the thickness of the area where the crushed portion 17 is located is intentionally designed to be thinner than the main portion of the frame 1. It should be noted that the aforementioned "main portion of the frame 1" refers to the core and basic structural portion of the frame 1, and does not include other additional, functional, or decorative portions, such as screws or anti-slip patterns. Furthermore, the main portion of the frame 1 typically has a thicker and stronger structure, providing sufficient strength and stability to enable the crushable optical accessory adapter ring A to be used normally. Furthermore, the crushed portion 17 can be adjacent to the force application portion 15. Therefore, when a force is applied to the force application portion 15 and it moves in a first direction, the force is transmitted to the main portion of the frame 1. Because the crushed portion 17 is thin, its structural strength is weaker, and as a result, it is less resistant to force than the rest of the frame 1. In this situation, the crushed portion 17 first reaches its endurance limit, deforms, and begins to fracture. The above-mentioned deformation and fracture concentrates more force in the area where the crushed portion 17 is located, accelerating the deformation and fracture of the crushed portion 17, resulting in the frame 1 being destroyed or torn along the extension direction of the crushed portion 17. It is particularly noted here that the term "adjacent" in this invention refers to two structural features being located close to each other, and when one structural feature is subjected to a force, the force can be transmitted to and affect the other structural feature. Those skilled in the art can easily and clearly understand the term "adjacent" based on the description and drawings of this invention. In the best embodiment, "adjacent" can indicate that the two structural features are within a shortest distance of 5 millimeters in three-dimensional space.

[0030] Referring back to FIGS. 2 to 6, in the first embodiment, the crushed portion 17 extends along the front-to-rear direction (i.e., the axial direction) of the frame 1. Here, the crushed portion 17 can be recessed into the inner wall surface of the second adapter end D2. In some embodiments, the crushed portion 17 can be located only on the inner wall surface of the frame 1 that has the second connecting portion 13 (the crushed portion 17 near the top in FIGS. 2 and 4). In some embodiments, the crushed portion 17 can be located on both the inner wall surface of the frame 1 that has the second connecting portion 13 and the inner wall surface that does not have the second connecting portion 13 (the crushed portion 17 near the bottom in FIGS. 2 and 4). The aforementioned "inner wall surface that does not have the second connecting portion 13" refers to the shoulder formed by the connection region between the second adapter end D2 and the first adapter end D1. Furthermore, the crushed portion 17 has an arc-shaped recessed groove shape, and its thinnest portion can be 0.1 to 0.3 millimeters (but is not limited to this).

[0031] 2 to 6, in the first embodiment, the frame 1 further includes at least one auxiliary crushing portion 171 to further enhance the breakability of the frame 1. The auxiliary crushing portion 171 may be recessed in the outer wall surface of the first adapter end D1 and disposed substantially opposite one of the crushing portions 17. In this manner, when a user pulls the force application portion 15, the force applied to the force application portion 15 deforms and breaks the frame 1 along the crushing portion 17 and the auxiliary crushing portion 171. In some embodiments, the auxiliary crushing portion 171 may be located only on the outer wall surface of the frame 1 that has the first connecting portion 11 (the auxiliary crushing portion 171 near the bottom in FIGS. 5 and 6). In some embodiments, the auxiliary crushing portion 171 may be located on both the outer wall surface of the frame 1 that has the first connecting portion 11 and the outer wall surface that does not have the first connecting portion 11 (the auxiliary crushing portion 171 near the top in FIGS. 5 and 6). The aforementioned "external wall surface not having the first connecting portion 11" refers to the shoulder formed by the connecting region between the first adapter end D1 and the second adapter end D2. Furthermore, the auxiliary crushed portion 171 has an arc-shaped recessed groove shape, and its thinnest part can be (but is not limited to) 0.1 to 0.3 mm.

[0032] 2 to 6, in the first embodiment, the frame 1 is provided with, but is not limited to, a plurality of force application portions 15, crushing portions 17, and auxiliary crushing portions 171. In other embodiments of the present invention, the frame 1 can have any number of force application portions 15, crushing portions 17, and auxiliary crushing portions 171 according to product needs, and the number can be at least one. Alternatively, the frame 1 can have only the force application portion 15 and the crushing portion 17. Furthermore, the crushing portions 17 and the auxiliary crushing portions 171 mentioned in the first embodiment can be simultaneously disposed on the frame 1, or only one of them can be selected and disposed on the frame 1, thereby increasing the flexibility in the production of the collapsible optical accessory adapter ring A.

[0033] Referring again to FIGS. 1 to 6, improper engagement between the collapsible optical accessory adapter ring A and the second optical accessory F can occur due to issues such as an inaccurate mounting angle, poor thread quality, or dirt clogging the thread gap. This can lead to thread jamming (thread locking) between the collapsible optical accessory adapter ring A and the second optical accessory F. In this case, the user applies force to the force application portion 15 by hand or with a disassembly tool, causing the frame 1 to break along the extension direction of each collapsible portion 17. This deformation causes the frame 1 to break and deform. This deformation typically causes the two ends of the corresponding breakage portion of the frame 1 to move away from each other, resulting in a loss of the roundness of the collapsible optical accessory adapter ring A. As a result, the user can then directly apply force to the frame 1 to easily remove it from the second optical accessory F without damaging the second optical accessory F. Additionally, although this removal method renders the collapsible optical accessory adapter ring A non-reusable, the price of the collapsible optical accessory adapter ring A is generally much cheaper than the second optical accessory F (e.g., a polarizing filter, an ND filter, etc.), and it can be considered a consumable item.

[0034] Note that the following describes several aspects of the collapsible optical accessory adapter ring A that differ from the first embodiment, and the following description will focus mainly on the differences. In a second embodiment of the present invention, as shown in FIGS. 7 and 8 , a frame 1 is provided with two force application portions 25, two crushed portions 27, and an auxiliary crushed portion 271. The force application portion 25 is located on the outer wall surface of the second adapter end D2 of the frame 1 and is provided with a through-hole 250 (but is not limited to this). The crushed portion 27 is located on the inner wall surface of the second adapter end D2 and adjacent to the force application portion 25. The auxiliary crushed portion 271 is located in the connection region between the first adapter end D1 and the second adapter end D2 and extends along the circumferential direction of the frame 1. At least one end of the auxiliary crushed portion 271 is adjacent to or connected to the crushed portion 27. In the second embodiment, the cross-sectional structure of the auxiliary crushed portion 271 is, but is not limited to, a V-shaped groove. When a user applies force to each force application portion 25 by hand or using a removal tool, the crushing portion 27 first deforms and breaks along the axial direction of the frame 1, and then the auxiliary crushing portion 271 deforms and breaks along the circumferential direction of the frame 1, causing the frame 1 to break and tear.

[0035] Continuing from the above, please refer to FIGS. 7 and 8 again. In the second embodiment, at least one fixing portion 20 is provided on the outer wall surface of the frame 1, and the fixing portion 20 can fix the collapsible optical accessory adapter ring A to other peripheral devices (e.g., a light shielding hood). Specifically, the fixing portion 20 includes (but is not limited to) two sheet bodies, each of which is spaced a certain distance apart, allowing the threaded structure of the light shielding hood to extend between them to achieve a screw-in or screw-out effect. However, it should be noted in advance that in other embodiments of the present invention, the actual structure of the fixing portion 20 may vary depending on the type of peripheral device.

[0036] In a third embodiment of the present invention, as shown in FIGS. 9 to 11B, an aperture 30 is provided on the outer peripheral surface of the second adapter end D2 of the frame 1. The aperture 30 has a diameter G1 on the outer wall surface (outer peripheral surface) of the frame 1 that is smaller than a diameter G2 on the inner wall surface (inner peripheral surface) of the frame 1, thereby forming a force application inclined surface 32. The aperture 30 and the force application inclined surface 32 together can constitute a force application portion 35 of the present invention. Furthermore, the crushed portion 37 is recessed in the outer peripheral surface of the second adapter end D2 and extends along the circumferential direction of the frame 1, but this is not limited thereto. In other embodiments, the crushed portion 37 may be recessed in the inner peripheral surface of the second adapter end D2, or may be recessed simultaneously in both the outer and inner peripheral surfaces of the second adapter end D2. Furthermore, a portion of the crushed portion 37 may be disposed adjacent to the force application portion 35. When a user inserts a removal tool into the hole 30 at an oblique angle and presses it against the force application inclined surface 32, it is possible to apply a force to the force application inclined surface 32 (this corresponds to applying a force to the force application portion 35). In some embodiments, (but not limited to) a support inclined surface 34 is provided at a position corresponding to the force application inclined surface 32, and the removal tool comes into close contact with the support inclined surface 34 and can apply a force to the force application inclined surface 32 using the support inclined surface 34 as a fulcrum. Furthermore, when the force application portion 35 moves in a first direction (for example, outward in the circumferential direction), some of the crushing portions 37 adjacent to the force application portion 35 are first deformed and broken, and then the user can pull the force application portion 35 to tear the frame 1 along the extension direction of the crushing portions 37. In this way, if the collapsible optical accessory adapter ring A is mistakenly mated with the second optical accessory F of Figure 1, the user can use the force application portion 35 and the collapsing portion 37 to break the connection between the collapsible optical accessory adapter ring A and the second optical accessory F, avoiding damaging the second optical accessory F.

[0037] In light of the above, in order to improve and accelerate the deformation and fracture state between the force application portion 35 and the crushed portion 37, as shown in FIGS. 9 to 11B, in a third embodiment, the force application portion 35 may be provided with at least one recessed region 351. The recessed region 351 may be connected to the crushed portion 37, and the thickness of the recessed region 351 may be the same as or smaller than the thickness of the crushed portion 37. As shown in FIG. 11A, the force application portion 35 is provided with two recessed regions 351. One recessed region 351 is formed to be recessed inward from the outer peripheral surface of the frame 1, and the other recessed region 351 is formed to be recessed outward from the inner peripheral surface of the frame 1, but this is not limited thereto. In other embodiments according to the present invention, only one recessed region 351 may be provided in the force application portion 35, and may be formed to be recessed from the outer peripheral surface or the inner peripheral surface. Furthermore, when the directions in which the crushed portion 37 and the recessed region 351 are recessed are different, for example, when the crushed portion 37 is recessed inward from the outer peripheral surface of the frame 1 and the recessed region 351 is recessed outward from the inner peripheral surface of the frame 1, the recessed region 351 does not communicate with the crushed portion 37 but is located adjacent to the crushed portion 37. This increases the effect of stress concentration when the force application portion 35 receives force, making it easier for a breaking point to form in the recessed region 351, which then extends to the crushed portion 37, forcing the crushed portion 37 to deform and break.

[0038] Again, as shown in FIGS. 9 to 11B, at least one decorative block 38 is disposed on the frame 1 so as to protrude outward. In the third embodiment, the decorative block 38 is disposed in a ring shape extending circumferentially around the frame 1. The decorative block 38 can be located between the first connecting portion 11 and the crushed portion 37 and can be coated with a reflective material, pigment, metallic coating, or a tooth-like anti-slip structure. This increases the variety of appearances of the crushable optical accessory adapter ring A. Furthermore, at least one anti-slip portion 39 can be provided on the outer surface of the second adapter end D2 of the frame 1. Each anti-slip portion 39 can be configured with a structure that forms a rough surface, such as a depression, a convex pattern, or grain, which can increase friction when the frame 1 is gripped and rotated. In this way, the design of the anti-slip portion 39 allows the user to more stably hold the frame 1 and connect or disconnect the first optical accessory L or second optical accessory F shown in FIG. 1 to the crushable optical accessory adapter ring A.

[0039] In a fourth embodiment of the present invention, as shown in FIGS. 12 and 13 , a frame 1 is provided with a force application portion 45, a plurality of crushed portions 47, and an auxiliary crushed portion 471. Here, the force application portion 45 is at least one convex block, and each crushed portion 47 is recessed inward from the outer wall surface (outer peripheral surface) of the frame 1, and has a V-shaped cross section (however, in other embodiments, the cross section may be U-shaped, W-shaped, etc.), and at least one crushed portion 47 is adjacent to the force application portion 45. Furthermore, like the crushed portion 37 in the third embodiment shown in FIG. 11B , the auxiliary crushed portion 471 is provided annularly in the circumferential direction of the frame 1 and is located adjacent to each crushed portion 47. The auxiliary crushed portion 471 can be recessed from the outer wall surface (outer peripheral surface) or the inner wall surface (inner peripheral surface) of the frame 1. When an external force is applied to the force application portion 45, the frame 1 can be deformed and broken sequentially along the extension direction of the crushed portions 47 and auxiliary crushed portions 471. In a modification of the fourth embodiment, the crushed portions 47 can be recessed outward from the inner wall surface (inner circumferential surface) of the frame 1, such as the middle crushed portion 47 shown in FIG. 14. Furthermore, in other embodiments of the present invention, the number and arrangement of the crushed portions 47 and auxiliary crushed portions 471 can be adjusted according to product needs. For example, each crushed portion 47 and auxiliary crushed portion 471 can be recessed outward from the inner wall surface (inner circumferential surface) of the frame 1, thereby maintaining the integrity of the appearance of the frame 1. Furthermore, in the fourth embodiment, the crushed portions 47 are arranged in the circumferential direction. In FIG. 12, the crushed portions 47 are arranged vertically. However, in other embodiments, the crushed portions 47 can be arranged along the axial direction, i.e., the size of the crushed portions 47 can be reduced and they can be arranged sequentially in the left-right direction of FIG. 12.

[0040] In a fifth embodiment of the present invention, as shown in FIGS. 15A and 15B , the force application portion 55 takes the form of an internally threaded groove or a threaded hole into which a screw tool (e.g., a screw, a screwdriver) is screwed. Two crushing portions 57 are disposed on opposite sides of the force application portion 55, but are not limited thereto. When a user tightens the force application portion 55 using a screw tool, the screw tool applies a force to the force application portion 55, causing movement in a first direction, deforming and breaking at least one of the crushing portions 57 and destroying the roundness of the frame 1. In another embodiment, the frame 1 is provided with an auxiliary crushing portion (not shown), allowing the user to tear the frame 1 along the auxiliary crushing portion. Alternatively, the force application portion 55 can be used in combination with the crushing portion 37 and recessed region 351 shown in the third embodiment of FIG. 11B (e.g., a recessed region is provided at at least one end of the internally threaded groove or screw hole), or in combination with only the crushing portion 37 of the third embodiment. When a user tightens the screw tool onto the force application portion 55, the effect of the small thickness of the crushed portion 37 and / or recessed area 351 can cause a fragile breaking effect.

[0041] In a sixth embodiment of the present invention, as shown in FIG. 16 , the crushing portion 67 is composed of a plurality of holes 670, which are arranged along the circumferential direction of the frame 1. The minimum spacing between adjacent holes 670 is 0.1 mm to 0.3 mm (but is not limited to this). Therefore, after a user applies force to the force application portion 65 (e.g., a convex block) by hand and pulls the force application portion 65 outward from the frame 1, the wall of the adjacent hole 670 close to the force application portion 65 is crushed and broken due to its thinness. As a result, the frame 1 is destroyed along the extension direction of the crushing portion 67 (i.e., the arrangement direction of the holes 670). However, in other embodiments of the present invention, the holes 670 are arranged along the axial direction of the frame 1 (such as the left-right direction in FIG. 16 ), and the same effect of destroying the frame 1 as described above can be achieved.

[0042] In the seventh embodiment of the present invention, as shown in FIGS. 17 and 18 , the second adapter end D2 of the frame 1 is larger than the first adapter end D1, forming a shoulder 76 between the second adapter end D2 and the first adapter end D1. An inclined surface 761 is provided on the outer side of the shoulder 76, and the inclined surface 761 is inclined from the second adapter end D2 toward the first adapter end D1. A localized portion of the inclined surface 761 corresponds to the connection point between the two inner wall surfaces of the second adapter end D2, and the thickness of this portion is thinner than other portions, thereby forming a crushed portion 77 (shown within the chain-line circle in FIG. 18 ). When a user applies force to the force application portion 75 adjacent to the crushed portion 77, the force transmitted from the force application portion 75 to the frame 1 deforms and breaks the crushed portion 77 (particularly the portion corresponding to the connection point between the two inner wall surfaces) due to excessive stress, and the frame 1 is destroyed along the extension direction of the crushed portion 77.

[0043] In an eighth embodiment of the present invention, as shown in FIG. 19 , the inner wall surface (inner peripheral surface) of the frame 1 is recessed outward to form a force application portion 85 (i.e., the force application portion 85 is a recessed area) and a crushed portion 87. Here, the recess depth of the crushed portion 87 is greater than that of the force application portion 85. When the second optical accessory F shown in FIG. 1 is mated with the frame 1, the force application portion 85 and the crushed portion 87 form an exposed gap between the second optical accessory F and the frame 1. A user can insert a removal tool (e.g., a flathead screwdriver) into the gap and apply an outward force to deform and break the crushed portion 87. It should be noted that in the above structure, the force application portion 85 and the crushed portion 87 can be integrated into one piece. In other words, the force applied by the removal tool is not limited to being applied at the position of the force application portion 85, but can also be applied at a position corresponding to the crushed portion 87. In this case, the crushed portion 87 simultaneously performs the functions of the force application portion 85 and the crushed portion 87. Furthermore, the frame 1 is provided with the auxiliary crushing portion 471 shown in the fourth embodiment of FIG. 12, and the frame 1 can be broken sequentially along the extending direction of the crushing portion 87 and the auxiliary crushing portion 471.

[0044] In light of the above, as shown in FIGS. 1 to 19 , the crushable optical accessory adapter ring A of the present invention addresses improper fitting by reducing the thickness of the frame 1. The user can simply apply external force to the force application portions 15, 25, 35, 45, 55, 65, 75, and 85 to cause the crushed portions 17, 27, 37, 47, 57, 67, 77, and 87 to burst, allowing the second optical accessory F to be easily separated from the frame 1. This significantly improves the difficulty of conventional adapter rings to be broken by external force. Furthermore, the present invention provides a configuration in which the crushable optical accessory adapter ring A of the present invention can be broken using either hands or a removal tool (including a screw tool), eliminating the need to worry about being unable to remove a lens due to improper installation. This allows the user to use the crushable optical accessory adapter ring A of the present invention in both indoor and outdoor photography environments. However, the above-described content is merely a preferred embodiment of the present invention, and the scope of the claimed rights of the present invention is not limited thereto. Equivalent modifications that can be easily conceived by a person skilled in the art based on the technical content disclosed in the present invention are also within the scope of protection of the present invention.
