Abstract
Description
本創作是關於一種濾鏡組，特別是關於一種包含二鏡片的濾鏡組。This creation relates to a filter set, and more particularly to a filter set comprising two lenses.
濾鏡是一種裝設在鏡頭前方的攝影輔助裝置，除了可用來保護鏡頭之外，也能夠對光的不同波段進行選擇性吸收，從而在攝影作品上形成特殊的光影效果。一般常用的濾鏡係如偏光鏡或減光鏡，偏光鏡的原理主要是設計成只允許某一光軸的光線通過，以將不具偏極性的自然光轉化為偏極光，因此偏光鏡可以把非金屬物體表面、水面等處的反光過濾消除，使色彩更鮮艷，而減光鏡則是可以減少入光量，故可幫助相機降低快門速度，以在強光照射的情況下，仍可使用大光圈拍出淺景深的效果。以往一個濾鏡組中僅裝設一片濾鏡，使用者雖然可以將多個不同效果的濾鏡組重疊使用以產生所需要的光影效果，但這樣的使用方式的缺點除了必須攜帶多個濾鏡組之外，還會因為重疊多個濾鏡組而導致取景角度縮小，故後來有人便設計出一種裝設有兩片濾鏡的濾鏡組。The filter is a photographic aid installed in front of the lens. In addition to protecting the lens, it can selectively absorb different wavelengths of light to create a special light and shadow effect on the photographic work. Generally, the commonly used filter is a polarizer or a dimming mirror. The principle of the polarizer is mainly designed to allow only a certain optical axis to pass through, so as to convert the non-polarized natural light into a polarized light, so the polarizer can The reflective filtering on the surface of metal objects, water surface, etc. eliminates the color, and the dimming mirror can reduce the amount of light entering, so it can help the camera to reduce the shutter speed, so that it can still use large aperture in the case of strong light. Take a shallow depth of field effect. In the past, only one filter was installed in a filter group. Although the user can use multiple filter sets with different effects to create the desired light and shadow effect, the disadvantage of such a use method is that it must carry multiple filters. In addition to the group, the framing angle is also reduced by overlapping a plurality of filter groups, so that a filter group equipped with two filters was later designed.
現有技術之裝設有兩片濾鏡之濾鏡組，例如台灣第I591413號發明專利所提出的濾鏡組中，其中一片濾鏡的位置固定、另一片濾鏡可轉動。以在該濾鏡組中裝設兩片偏光鏡為例，當該二偏光鏡的光軸相互平行時，可通過該二偏光鏡的光最多，故呈現最亮的偏光效果；當該二偏光鏡的光軸相互垂直時，可通過該二偏光鏡的光最少，故呈現最暗的偏光效果。也就是說，將二偏光鏡搭配使用，除了有過濾反光、使色彩鮮豔的效果之外，還兼具減光的效果，且該濾鏡組可調整的偏光、減光效果變化主要在該二偏光鏡之光軸相互平行至該二偏光鏡之光軸相互垂直的0度到90度之間。A filter set provided with two filters is provided in the prior art. For example, in the filter set proposed in Japanese Patent No. I591413, one of the filters is fixed in position and the other filter is rotatable. Taking two polarizing mirrors in the filter group as an example, when the optical axes of the two polarizers are parallel to each other, the light passing through the two polarizers is the most, so that the brightest polarizing effect is exhibited; when the polarized light is polarized; When the optical axes of the mirrors are perpendicular to each other, the light passing through the two polarizers is minimized, so that the darkest polarizing effect is exhibited. That is to say, the two polarizers are used together, in addition to filtering and reflecting, and the effect of color is bright, and also has the effect of dimming, and the polarization and dimming effects of the filter group can be adjusted mainly in the second The optical axes of the polarizers are parallel to each other until the optical axes of the two polarizers are between 0 and 90 degrees perpendicular to each other.
而為了使鏡片能相對轉動，前述濾鏡組包含了一固定環及一調整環，且調整環是可轉動地設置於固定環內，而二偏光鏡即分別固定於固定環及調整環上。為了讓使用者能轉動調整環及其上的偏光鏡，現有的固定環上形成有一導槽，而調整環設有一驅動桿，且驅動桿穿設於導槽內而能沿導槽移動。當驅動桿沿導槽移動時，便於動了調整環及其上的偏光鏡轉動。然而，這轉於濾鏡組上形成有導槽的設計，灰塵或毛屑等汙垢較容易卡在導槽內，甚至可能經由導槽而進入濾鏡組內。如此，不僅難以清理，嚴重時還有可能影響成像品質。In order to make the lens relatively rotate, the filter set includes a fixing ring and an adjusting ring, and the adjusting ring is rotatably disposed in the fixing ring, and the two polarizers are respectively fixed on the fixing ring and the adjusting ring. In order to enable the user to rotate the adjusting ring and the polarizer thereon, a guide groove is formed on the existing fixing ring, and the adjusting ring is provided with a driving rod, and the driving rod is disposed in the guiding groove to be movable along the guiding groove. When the drive rod moves along the guide groove, it is easy to move the adjustment ring and the polarizer on the rotation. However, this turns to the design of the guide groove formed on the filter group, and dirt such as dust or dander is more likely to get caught in the guide groove, and may even enter the filter group via the guide groove. In this way, it is not only difficult to clean, but also may affect the image quality in severe cases.
有鑑於此，提出一種更佳的改善方案，乃為此業界亟待解決的問題。In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.
本創作的主要目的在於，提出一種二環式濾鏡組，其包含兩濾鏡，且固定兩濾鏡的二環體間沒有間隙，因此沒有空間容納汙垢，且汙垢也不會由二環體間進入二濾鏡間。The main purpose of this creation is to propose a two-ring filter set that includes two filters, and there is no gap between the two ring bodies that fix the two filters, so there is no space to accommodate dirt, and the dirt is not bound by the two-ring body. Enter between the two filters.
為達上述目的，本創作所提出的二環式濾鏡組具有： 一第一環體，其具有： 一固定側，其能固設於該鏡頭；及 一前側，其相對於該固定側； 一第二環體，其設置於該第一環體的前側，並具有： 一外環部，其設置於該第一環體； 一內環部，其可轉動地容設於該外環部內； 一操作部，其固設於該內環部，並向前凸出至該外環部外；及 複數個滾動件，其可轉動地被該外環部及該內環部所夾掣； 一第一鏡片，其被套設於該外環部內；以及 一第二鏡片，其被套設於該內環部內，且該第二鏡片與該第一鏡片平行且間隔設置。In order to achieve the above object, the two-ring filter set proposed by the present invention has: a first ring body having: a fixed side that can be fixed to the lens; and a front side opposite to the fixed side; a second ring body disposed on the front side of the first ring body and having: an outer ring portion disposed on the first ring body; an inner ring portion rotatably received in the outer ring portion An operating portion fixed to the inner ring portion and protruding forwardly to the outside of the outer ring portion; and a plurality of rolling members rotatably sandwiched by the outer ring portion and the inner ring portion; a first lens is sleeved in the outer ring portion; and a second lens is sleeved in the inner ring portion, and the second lens is disposed parallel to and spaced apart from the first lens.
因此，本創作的優點在於，外環部及內環部能藉由滾動件順利地相對轉動，且固設於內環部上的操作部自外環部前側凸出，讓使用者輕易地透過推動操作部操控內環部轉動，而不需要透過外環部上貫穿形成溝槽，因此汙垢不易進入外環部與內環部之間，更不會進入第一鏡片與第二鏡片之間。Therefore, the present invention has the advantages that the outer ring portion and the inner ring portion can be smoothly rotated relative to each other by the rolling member, and the operation portion fixed on the inner ring portion protrudes from the front side of the outer ring portion, so that the user can easily pass through The driving operation portion controls the rotation of the inner ring portion without forming a groove through the outer ring portion, so that the dirt does not easily enter between the outer ring portion and the inner ring portion, and does not enter between the first lens and the second lens.
如前所述之二環式濾鏡組中，該內環部的外側面形成有複數個容槽，該等滾動件分別容置於其中一該容置槽內。In the two-ring filter set as described above, the outer side surface of the inner ring portion is formed with a plurality of pockets, and the rolling elements are respectively accommodated in one of the receiving grooves.
如前所述之二環式濾鏡組中，該外環部的內側面形成有一環凹槽，該等滾動件能於該環凹槽內滾動。In the two-ring filter set as described above, the inner side surface of the outer ring portion is formed with a ring groove, and the rolling members can roll in the ring groove.
如前所述之二環式濾鏡組中，該第二環體更具有一限位塊，其固設於該外環部的內側面，藉此該等滾動件無法通過該限位塊。In the two-ring filter set as described above, the second ring body further has a limiting block which is fixed to the inner side of the outer ring portion, so that the rolling members cannot pass through the limiting block.
如前所述之二環式濾鏡組中，當該限位塊抵靠於其中一該滾動件時，該第二鏡片的極軸與該第一鏡片的極軸的夾角小於90度。In the two-ring filter set as described above, when the limiting block abuts against one of the rolling elements, the polar axis of the second lens and the polar axis of the first lens are less than 90 degrees.
如前所述之二環式濾鏡組中，各該滾動件為滾珠。In the two-ring filter set as described above, each of the rolling members is a ball.
如前所述之二環式濾鏡組中，該外環部可轉動地設置於該第一環體；該內環部與該外環部之間轉動的阻力小於該外環部與該第一環體之間轉動的阻力。In the two-ring filter set as described above, the outer ring portion is rotatably disposed on the first ring body; the resistance between the inner ring portion and the outer ring portion is smaller than the outer ring portion and the first The resistance to rotation between a ring.
首先請參考圖1至圖3。本創作提出一種二環式濾鏡組，其能固設於一鏡頭。本創作的二環式濾鏡組具有一第一環體10、一第二環體20、一第一鏡片30、及一第二鏡片40，並選擇性地具有複數個滾動件23及一限位塊24。First, please refer to Figure 1 to Figure 3. This creation proposes a two-ring filter set that can be attached to a lens. The two-ring filter set of the present invention has a first ring body 10, a second ring body 20, a first lens 30, and a second lens 40, and optionally has a plurality of rolling elements 23 and a limit Bit block 24.
第一環體10具有一固定側及一前側。固定側能固設於鏡頭，而前側為第一環體10上相對於固定側的另一側。第一環體10做為與鏡頭固定的部分，因此其固定側可形成有螺紋或卡槽。The first ring body 10 has a fixed side and a front side. The fixed side can be fixed to the lens, and the front side is the other side of the first ring body 10 with respect to the fixed side. The first ring body 10 is a portion that is fixed to the lens, so that the fixed side thereof can be formed with a thread or a card slot.
第二環體20可設置於第一環體10的前側。本實施例中，第二環體20具有一外環部21、一內環部22、複數個滾動件23，並可選擇性地具有限位塊24及操作部25。外環部21可轉動地被套設於第一環體10內，而第一鏡片30被套設於外環部21內，但於其他實施例中外環部21也可不能轉動地與第一環體10相固設。於本實施例中，外環部21的內側面形成有一環凹槽210，但於其他實施例中也可不具有環凹槽210。The second ring body 20 may be disposed on the front side of the first ring body 10. In this embodiment, the second ring body 20 has an outer ring portion 21, an inner ring portion 22, a plurality of rolling members 23, and optionally a limiting block 24 and an operating portion 25. The outer ring portion 21 is rotatably sleeved in the first ring body 10, and the first lens 30 is sleeved in the outer ring portion 21. However, in other embodiments, the outer ring portion 21 can also be non-rotatably coupled to the first ring body. 10 phase is fixed. In the present embodiment, the inner side surface of the outer ring portion 21 is formed with a ring groove 210, but in other embodiments, the ring groove 210 may not be provided.
內環部22可轉動地與外環部21相互套設。於本實施例中，內環部22可轉動地容設於外環部21內。具體而言，內環部22的外周面可被外環部21所覆蓋，但內環部22的前側面未被外環部21所覆蓋，且內環部22的前側面可較外環部21的前側面更靠近第一環體10。而本實施例中第二環體20具有操作部25，其固設於內環部22上並向前凸出至外環部21外。換言之，操作部25徑向凸出於外環部21的前側面外，以供使用者操作轉動第二環體內環部22。本實施例中，操作部25為一環形，但於其他實施例中亦可為一向前方凸出的凸塊。本實施例中，操作部25與內環部22一體成形，但其他實施例中操作部25可附加於內環部22的另一元件。內環部22的外側面形成有複數個容置槽220。容置槽220可用於容置滾動件23。第二鏡片40其被套設於內環部22內，且第二鏡片40與第一鏡片30平行且間隔設置。The inner ring portion 22 is rotatably sleeved with the outer ring portion 21. In the present embodiment, the inner ring portion 22 is rotatably received in the outer ring portion 21. Specifically, the outer circumferential surface of the inner ring portion 22 may be covered by the outer ring portion 21, but the front side surface of the inner ring portion 22 is not covered by the outer ring portion 21, and the front side surface of the inner ring portion 22 may be larger than the outer ring portion The front side of the 21 is closer to the first ring body 10. In the present embodiment, the second ring body 20 has an operation portion 25 which is fixed to the inner ring portion 22 and protrudes forward to the outside of the outer ring portion 21. In other words, the operating portion 25 projects radially outward of the front side of the outer ring portion 21 for the user to operate to rotate the second inner ring portion 22. In this embodiment, the operating portion 25 is a ring shape, but in other embodiments, it may be a convex portion that protrudes forward. In the present embodiment, the operation portion 25 is integrally formed with the inner ring portion 22, but the operation portion 25 may be attached to another member of the inner ring portion 22 in other embodiments. The outer side surface of the inner ring portion 22 is formed with a plurality of accommodating grooves 220. The accommodating groove 220 can be used to accommodate the rolling member 23. The second lens 40 is sleeved within the inner ring portion 22, and the second lens 40 is disposed parallel to and spaced from the first lens 30.
滾動件23可為滾珠、滾針、或滾柱，並可轉動地被外環部21及內環部22所夾掣，藉此使內環部22能相對於外環部21轉動。具體而言，滾動件23分別容置於內環部22外側面的其中一容置槽220內，並部分凸出於容置槽220，且滾動件23凸出的部分位於外環部21的環凹槽210內。因此，滾動件23能於容置槽220及環凹槽210內滾動。而限位塊24固設於外環部21的內側面，且本實施例中是固設於環凹槽210內，並自環凹槽210的底面凸出，藉此滾動件23無法通過限位塊24，並限制了內環部22能相對於外環部21轉動的角度。本實施例中限位塊24與外環部21為兩個獨立可分的元件，但於其他實施例中限位塊24可與外環部21一體成形，因此可為自外環部21的環凹槽210中凸出的一凸塊。The rolling member 23 may be a ball, a needle, or a roller, and is rotatably sandwiched by the outer ring portion 21 and the inner ring portion 22, whereby the inner ring portion 22 is rotatable relative to the outer ring portion 21. Specifically, the rolling members 23 are respectively received in one of the accommodating grooves 220 of the outer side surface of the inner ring portion 22, and partially protrude from the accommodating groove 220, and the protruding portion of the rolling member 23 is located at the outer ring portion 21. Inside the ring groove 210. Therefore, the rolling member 23 can roll in the receiving groove 220 and the ring groove 210. The limiting block 24 is fixed on the inner side surface of the outer ring portion 21, and is fixed in the ring groove 210 in the embodiment, and protrudes from the bottom surface of the ring groove 210, so that the rolling member 23 cannot pass the limit. The block 24 limits the angle at which the inner ring portion 22 can rotate relative to the outer ring portion 21. In this embodiment, the limiting block 24 and the outer ring portion 21 are two independently separable elements. However, in other embodiments, the limiting block 24 can be integrally formed with the outer ring portion 21, and thus can be from the outer ring portion 21. A bump protruding in the ring groove 210.
由於本實施例中，內環部22與外環部21之間有滾動件23，而外環部21與第一環體10沒有滾動件，使得內環部22與外環部21之間的阻力小於外環部21與第一環體10之間的阻力。因此，當使用者施力轉動外環部21時，內環部22會跟著外環部21轉動，當使用者施力轉動內環部22時，外環部21因為與第一環體10之間的阻力而不會跟著內環部22轉動。In the present embodiment, there is a rolling member 23 between the inner ring portion 22 and the outer ring portion 21, and the outer ring portion 21 and the first ring body 10 have no rolling members, so that the inner ring portion 22 and the outer ring portion 21 are The resistance is smaller than the resistance between the outer ring portion 21 and the first ring body 10. Therefore, when the user applies the force to rotate the outer ring portion 21, the inner ring portion 22 will rotate along with the outer ring portion 21, and when the user applies the force to rotate the inner ring portion 22, the outer ring portion 21 is the same as the first ring body 10. The resistance between the two does not follow the inner ring portion 22.
此外，由於內環部22與外環部21之間及外環部21與第一環體10之間可加入潤滑油以防止各元件間的磨損，但為了達到上述效果，內環部22與外環部21之間及外環部21與第一環體10之間所加入的潤滑油的阻尼係數可不相同。具體而言，內環部22與外環部21之間的潤滑油的阻尼係數可小於外環部21與第一環體10之間的潤滑油的阻尼係數，因此，同樣地，當使用者施力轉動外環部21時，內環部22會跟著外環部21轉動，當使用者施力轉動內環部22時，外環部21因為與第一環體10之間的阻力而不會跟著內環部22轉動。In addition, since lubricating oil can be added between the inner ring portion 22 and the outer ring portion 21 and between the outer ring portion 21 and the first ring body 10 to prevent wear between the elements, in order to achieve the above effects, the inner ring portion 22 and The damping coefficient of the lubricating oil added between the outer ring portions 21 and between the outer ring portion 21 and the first ring body 10 may be different. Specifically, the damping coefficient of the lubricating oil between the inner ring portion 22 and the outer ring portion 21 may be smaller than the damping coefficient of the lubricating oil between the outer ring portion 21 and the first ring body 10, and thus, similarly, when the user When the outer ring portion 21 is biased, the inner ring portion 22 will rotate along with the outer ring portion 21. When the user applies a force to rotate the inner ring portion 22, the outer ring portion 21 does not resist the resistance between the first ring body 10 and the first ring body 10. It will follow the inner ring portion 22 to rotate.
接著請參考圖3至圖5。在上述結構下，限位塊24僅能於兩相鄰的滾動件23間移動，因此內環部22能轉動的角度最大僅限於在夾設滾動件23的二相鄰的滾動件23間的範圍內。本實施例中，內環部22的容置槽220的數量等於滾動件23的數量，因此每個容置槽220內皆設有一滾動件23。但為了內環部22能轉動的角度增加，且仍保有足夠的滾動件23來減少摩擦力，滾動件23的數量可小於內環部22的容置槽220的數量，且其中二相鄰的滾動件23之間有至少一未容置有滾動件23的容置槽220，同時限位塊24位於該二滾動件23之間。藉此，限位塊24移動的範圍即不受容置槽220的限制。Please refer to FIG. 3 to FIG. 5 next. Under the above structure, the limiting block 24 can only move between the two adjacent rolling members 23, so that the angle at which the inner ring portion 22 can rotate is limited to the maximum between the two adjacent rolling members 23 sandwiching the rolling members 23. Within the scope. In this embodiment, the number of the receiving grooves 220 of the inner ring portion 22 is equal to the number of the rolling members 23, so that a rolling member 23 is disposed in each of the receiving grooves 220. However, in order to increase the angle at which the inner ring portion 22 can rotate, and still retain sufficient rolling members 23 to reduce the frictional force, the number of the rolling members 23 can be smaller than the number of the receiving grooves 220 of the inner ring portion 22, and two adjacent ones thereof There is at least one accommodating groove 220 between the rolling members 23 that does not accommodate the rolling members 23, and the limiting block 24 is located between the two rolling members 23. Thereby, the range in which the limiting block 24 moves is not limited by the receiving slot 220.
本實施例中，第一鏡片30及第二鏡片40皆為偏光鏡。因此若第一鏡片30及第二鏡片40的極軸被轉動至相垂直時，會於成像上產生十字紋。為了避免十字紋的產生，應防止第一鏡片30及第二鏡片40被轉動至其極軸相垂直。因此，當限位塊24抵靠於其中一滾動件23時，第二鏡片40的極軸與第一鏡片30的極軸的夾角小於90度。例如，可將限位塊24設置於第一鏡片30平行極軸的直徑線沿線上，且相鄰於限位塊24的其中一滾動件23設置於第二鏡片40垂直極軸的直徑線沿線上，由於滾動件23與限位塊24無法重合，因此無論如何轉動都不會使第一鏡片30與第二鏡片40的極軸相垂直。In this embodiment, the first lens 30 and the second lens 40 are both polarizers. Therefore, if the polar axes of the first lens 30 and the second lens 40 are rotated to be perpendicular to each other, a cross pattern is formed on the image. In order to avoid the generation of cross lines, the first lens 30 and the second lens 40 should be prevented from being rotated until their polar axes are perpendicular. Therefore, when the limiting block 24 abuts against one of the rolling members 23, the angle between the polar axis of the second lens 40 and the polar axis of the first lens 30 is less than 90 degrees. For example, the limiting block 24 can be disposed along the diameter line of the parallel polar axis of the first lens 30, and one of the rolling elements 23 adjacent to the limiting block 24 is disposed along the diameter line of the vertical axis of the second lens 40. In the above, since the rolling member 23 and the limiting block 24 cannot overlap, the first lens 30 and the polar axis of the second lens 40 are not perpendicular to each other.
於其他實施例中，也可將限位塊24設置於第一鏡片30垂直極軸的直徑線沿線上，且相鄰於限位塊24的其中一滾動件23設置於第二鏡片40平行極軸的直徑線沿線上，也能達到一樣的效果。甚至，再於其他實施例中，也可將限位塊24設置於順時針（或逆時針）偏離第一鏡片30平行極軸的直徑線沿線一角度的位置，且相鄰於限位塊24的其中一滾動件23設置同樣偏離於第二鏡片40平行極軸的直徑線同一角度的位置In other embodiments, the limiting block 24 may be disposed on the imaginary line of the vertical axis of the first lens 30, and one of the rolling members 23 adjacent to the limiting block 24 is disposed on the parallel pole of the second lens 40. The same effect can be achieved by the diameter line of the shaft along the line. Even in other embodiments, the limiting block 24 can be disposed at a position along the line of the diameter line of the parallel axis of the first lens 30 clockwise (or counterclockwise), and adjacent to the limiting block 24 One of the rolling members 23 is disposed at the same angle from the diameter line of the parallel polar axis of the second lens 40.
於其他實施例中，環凹槽210及容置槽220的設置位置可相反。亦即，外環部21的內側面形成有複數個容置槽，而內環部22的外側面形成有一環凹槽。因此，限位塊24也可相應地設於內環部22上。In other embodiments, the ring groove 210 and the receiving groove 220 may be disposed oppositely. That is, the inner side surface of the outer ring portion 21 is formed with a plurality of accommodating grooves, and the outer side surface of the inner ring portion 22 is formed with a ring groove. Therefore, the limiting block 24 can also be provided on the inner ring portion 22 accordingly.
於其他實施例中，可不具有滾動23件及限位塊24，但內環部22仍可於外環部21內滑動旋轉。於其他實施例中，可僅具有滾動件23而不具有限位塊24。In other embodiments, there may be no rolling 23 pieces and limiting pieces 24, but the inner ring portion 22 can still slide and rotate within the outer ring portion 21. In other embodiments, there may be only rolling elements 23 and no limiting blocks 24.
綜上所述，本創作的外環部21及內環部22能藉由滾動件23順利地相對轉動，且固設於內環部22上的操作部25自外環部21前側凸出，讓使用者輕易地透過推動操作部25操控內環部22轉動，而不需要透過外環部21上貫穿形成溝槽，因此汙垢不易進入外環部21與內環部22之間，更不會進入第一鏡片30與第二鏡片40之間。As described above, the outer ring portion 21 and the inner ring portion 22 of the present invention can be smoothly rotated by the rolling member 23, and the operation portion 25 fixed to the inner ring portion 22 protrudes from the front side of the outer ring portion 21, The user can easily control the rotation of the inner ring portion 22 by pushing the operating portion 25 without forming a groove through the outer ring portion 21, so that dirt does not easily enter between the outer ring portion 21 and the inner ring portion 22, and Entering between the first lens 30 and the second lens 40.
