為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。The above and other objects, features and advantages of the present invention will become more <RTIgt;
請參照圖1，其係繪示依照本發明一實施例之一種投影機收縮時之側面透視圖。在圖1中，投影機100包括底座102、 投影機本體104以及樞接段108與112組成之伸縮臂。其中，如熟習該項技藝者可以輕易知曉，樞接段之數量係為根據設計者設計時之實際需求而定，其數量並不以此為限。Please refer to FIG. 1 , which is a side perspective view of a projector when it is contracted according to an embodiment of the invention. In FIG. 1, the projector 100 includes a base 102, The projector body 104 and the telescopic arms of the pivoting segments 108 and 112. For example, those skilled in the art can easily know that the number of pivoting sections is determined according to the actual needs of the designer, and the number is not limited thereto.
在本實施例中，底座102係為用來與桌面或置放的物品作接觸，且係為於其上方。而樞接段108之第一端係與底座102於樞接點106的地方作樞接，樞接段108之第二端與樞接段112之第一端於樞接點110的地方作樞接，而樞接段112之第二端與投影機本體104之下表面於樞接點114的地方作樞接。其中，上述之樞接方式可以例如是貫孔鎖固方式或是圓球包覆方式(如中華民國公告號第M341614號第2圖所示)。舉例來說，而貫孔鎖固方式係為在樞接段108上有貫穿樞接段108之一貫孔(靠近樞接點106之位置)，然後再利用一ㄇ字形的固定片將樞接段108的第一端固定於底座102上。In this embodiment, the base 102 is for contacting the table top or the placed item and above it. The first end of the pivoting section 108 is pivotally connected to the base 102 at the pivot point 106. The second end of the pivoting section 108 and the first end of the pivoting section 112 are pivoted at the pivoting point 110. The second end of the pivoting section 112 is pivotally connected to the lower surface of the projector body 104 at the pivot point 114. The pivoting manner may be, for example, a through-hole locking method or a ball wrapping method (as shown in FIG. 2 of the Republic of China Announcement No. M341614). For example, the through hole locking method has a consistent hole (close to the pivot point 106) penetrating the pivoting section 108 on the pivoting section 108, and then the pivoting section is used by a U-shaped fixing piece. The first end of the 108 is secured to the base 102.
投影機本體104上係至少包括一投影單元116，此投影單元116係為輸出影像至投影布幕、牆壁或白板上，以供使用者觀看。在本實施例中，投影機本體104還包括各種投影機100應具有之單元，因其非本案之重點，故在此忽略未述。The projector body 104 includes at least one projection unit 116 for outputting images to a projection screen, a wall or a whiteboard for viewing by a user. In the present embodiment, the projector body 104 further includes various units that the projector 100 should have. Since it is not the focus of the present invention, it is omitted here.
請合併參照圖1與圖2，圖2係繪示依照本發明一實施例之一種投影機伸展時之側視圖。在圖1中，樞接段112與樞接段108之間的第一角度夾角與伸縮臂的關係為伸縮臂處於收縮的情況，因此底座102與投影機本體104係為接合狀態。其中，如熟習該項技藝者可以輕易知曉，為使底座102與投影機本體104能作緊密接合，在底座102與投影機本體104可配置一扣合結構(未繪示)。Referring to FIG. 1 and FIG. 2 together, FIG. 2 is a side view of the projector when it is extended according to an embodiment of the invention. In FIG. 1 , the relationship between the first angle between the pivoting section 112 and the pivoting section 108 and the telescopic arm is that the telescopic arm is in a contracted state, and thus the base 102 and the projector body 104 are in an engaged state. For example, those skilled in the art can easily know that in order to make the base 102 and the projector body 104 tightly coupled, a fastening structure (not shown) can be disposed on the base 102 and the projector body 104.
在圖2中，樞接段112與樞接段108之間的第二角度夾角與伸縮臂的關係為伸縮臂處於伸展的情況，因此底座102與投影機本體104之間係具有一距離。而底座102與投影機本體104之間距離的大小則為使用者根據投影之需要而調整，並非為一固定值。In FIG. 2, the relationship between the angle between the pivoting section 112 and the pivoting section 108 and the telescopic arm is such that the telescopic arm is extended, so that the base 102 has a distance from the projector body 104. The distance between the base 102 and the projector body 104 is adjusted by the user according to the needs of the projection, and is not a fixed value.
在本發明之較佳實施例中，第二夾角係大於第一夾角，而當樞接段108與樞接段112被設計為收縮時完全重疊時，則第一夾角為0度。In a preferred embodiment of the invention, the second angle is greater than the first angle, and when the pivoting section 108 and the pivoting section 112 are designed to completely overlap when contracted, the first angle is 0 degrees.
在本發明之較佳實施例中，底座102之形狀未必需如圖1與圖2般之凹字形，亦可以為一平面，其形狀並不以此為限。In the preferred embodiment of the present invention, the shape of the base 102 does not have to be a concave shape as shown in FIG. 1 and FIG. 2, and may be a flat surface, and the shape thereof is not limited thereto.
請繼續參照圖2，當伸縮臂伸展而使投影機本體104升起時，則使用者可旋轉投影機本體104，亦即，使用者可以在不移動或旋轉底座102之情況下，使投影機本體104相對於底座102做水平旋轉。也就是說，當投影機本體104被旋轉時，樞接段108與112並未隨著轉動。另外，在本實施例中亦可以設計為水平轉動樞接段108與112而使得投影機本體104被旋轉。Referring to FIG. 2, when the telescopic arm is extended to raise the projector body 104, the user can rotate the projector body 104, that is, the user can make the projector without moving or rotating the base 102. The body 104 is horizontally rotated relative to the base 102. That is, when the projector body 104 is rotated, the pivotal segments 108 and 112 do not rotate. In addition, in this embodiment, it is also possible to design the horizontal pivoting sections 108 and 112 to rotate the projector body 104.
請參照圖3，其係繪示依照本發明一實施例之一種投影機吊掛牆壁時之示意圖。在圖3中，投影機100係為吊掛於牆壁302上。在牆壁302上係配置有一T字形之掛勾(可以例如是釘子或勾狀物)122，而在底座102上配置有一勾槽120，此勾槽120係為用來容納掛勾122。因此，當將掛勾122被容納於勾槽120中時，則投影機100則可被吊掛於牆壁302上。Please refer to FIG. 3 , which is a schematic diagram of a projector hanging a wall according to an embodiment of the invention. In FIG. 3, projector 100 is suspended from wall 302. A T-shaped hook (which may be, for example, a nail or a hook) 122 is disposed on the wall 302, and a hook groove 120 is disposed on the base 102 for receiving the hook 122. Therefore, when the hook 122 is received in the hook groove 120, the projector 100 can be hung on the wall 302.
在本實施例中，當投影機本體104被升起後，使用者可調整投影機本體104與樞接段112之間的夾角，而使投影機本體104被調整為與牆壁垂直的地面平行，因此可使投影單元116面向布幕的方向。In this embodiment, after the projector body 104 is raised, the user can adjust the angle between the projector body 104 and the pivoting section 112, so that the projector body 104 is adjusted to be parallel to the ground perpendicular to the wall. Therefore, the projection unit 116 can be oriented in the direction of the curtain.
請合併參照圖2與圖3，在本實施例中，當伸縮臂伸展而使投影機本體104被升起後，使用者則可根據投影布幕之方向而水平的旋轉投影機本體104。另外，可再根據投影機本體104與投影布幕間之高度適時調整投影機本體104與樞接段112之夾角。Referring to FIG. 2 and FIG. 3 together, in the embodiment, after the telescopic arm is extended and the projector body 104 is raised, the user can horizontally rotate the projector body 104 according to the direction of the projection screen. In addition, the angle between the projector body 104 and the pivoting section 112 can be adjusted according to the height between the projector body 104 and the projection screen.
請參照圖4A與4B，其係分別繪示依照本發明一實施例之一種投影機之下表面的俯視示意圖以及依照本發明一實施例之圖4A之投影機之下表面沿著線A-A的剖面示意圖。在圖4A中，其係為圖1之底座102之下表面118的示意圖，而在下表面118上係配置有平衡裝置402a與402b。平衡裝置402a與402b之配置係為配置於下表面118的相對邊，且係為靠近下表面118之角落的位置，而其數量在此係以兩個為例作說明，但實際數量自當不以此為限。其中，平衡裝置402a與402b係為用於當圖1之投影機本體104升起時，為避免投影機100因其高度過高而導致重心不穩的平衡裝置。因此，平衡裝置402a與402b之面積大小以及突出於下表面118之面積為何，則均視投影機本體104所能升起之高度而定。4A and 4B are respectively a top plan view of a lower surface of a projector according to an embodiment of the present invention, and a cross section of the lower surface of the projector of FIG. 4A along line AA according to an embodiment of the invention. schematic diagram. In FIG. 4A, which is a schematic view of the lower surface 118 of the base 102 of FIG. 1, and balancing devices 402a and 402b are disposed on the lower surface 118. The balancing devices 402a and 402b are disposed on opposite sides of the lower surface 118 and are located near the corners of the lower surface 118. The number of the balancing devices 402a and 402b is illustrated by two examples, but the actual number is not This is limited to this. Wherein, the balancing devices 402a and 402b are balancing devices for avoiding the instability of the center of gravity of the projector 100 due to its height being too high when the projector body 104 of FIG. 1 is raised. Therefore, the size of the balancing devices 402a and 402b and the area of the lower surface 118 are both dependent on the height at which the projector body 104 can be raised.
在本實施例中，以平衡裝置402a為例，其係利用一中心軸404樞接於下表面118上。以圖4B來看，在下表面118上係具有一容納空間來容納平衡裝置402a，因此可使下表面118與平衡裝置402a可以為一平整的平面。另外，亦可將下表面118設計為一平整的平面，而將平衡裝置402a設計為疊加於下表面118上。當平衡裝置402a被翻轉時，則如圖4B之虛線所示，平衡裝置402a係為突出於下表面118，且與下表面118呈一平整的平面。In the present embodiment, the balancing device 402a is exemplified by a central shaft 404 pivotally connected to the lower surface 118. 4B, there is an accommodation space on the lower surface 118 for receiving the balancing device 402a so that the lower surface 118 and the balancing device 402a can be a flat surface. Alternatively, the lower surface 118 can be designed as a flat surface and the balancing device 402a can be designed to be superimposed on the lower surface 118. When the balancing device 402a is turned over, the balancing device 402a protrudes from the lower surface 118 and has a flat surface with the lower surface 118 as indicated by the dashed line in FIG. 4B.
請參照圖5，其係繪示依照本發明另一實施例之一種投影機之下表面的俯視示意圖。在圖5中，其係為圖1之底座102 之下表面118的示意圖，而在下表面118上係配置有平衡裝置502a與502b。平衡裝置502a與502b之配置係為配置於下表面118的相對邊，且係為靠近下表面118之角落的位置，而其數量在此係以兩個為例作說明，但實際數量自當不以此為限。其中，平衡裝置502a與502b係為用於當圖1之投影機本體104升起時，為避免投影機100因其高度過高而導致重心不穩的平衡裝置。因此，平衡裝置502a與502b之面積大小以及突出於下表面118之面積為何，則均視投影機本體104所能升起之高度而定。Referring to FIG. 5, a schematic top view of a lower surface of a projector according to another embodiment of the present invention is shown. In FIG. 5, it is the base 102 of FIG. A schematic view of the lower surface 118 is provided with balancing devices 502a and 502b disposed on the lower surface 118. The balance devices 502a and 502b are disposed on opposite sides of the lower surface 118 and are located near the corners of the lower surface 118, and the number thereof is illustrated by two examples, but the actual number is not This is limited to this. The balancing devices 502a and 502b are balancing devices for avoiding the instability of the center of gravity of the projector 100 due to its height being too high when the projector body 104 of FIG. 1 is raised. Therefore, the size of the balancing devices 502a and 502b and the area of the lower surface 118 are both dependent on the height at which the projector body 104 can be raised.
在本實施例中，平衡裝置502a係以中心軸504為中心作水平旋轉，因此平衡裝置502a未被旋轉時，其係為在下表面118之範圍內。當平衡裝置502a被旋轉時，其係為突出於下表面118。In the present embodiment, the balancing device 502a is horizontally rotated about the central axis 504. Therefore, when the balancing device 502a is not rotated, it is within the range of the lower surface 118. When the balancing device 502a is rotated, it protrudes from the lower surface 118.
請參照圖6A與6B，其係分別繪示依照本發明又一實施例之一種投影機之下表面的俯視示意圖以及依照本發明一實施例之圖6A之投影機之下表面沿著線B-B的剖面示意圖。在圖6B中，平衡裝置602a係為可配置於底座102之厚度中，亦即在底座102之厚度中配置一容納空間以收納平衡裝置602a，而此容納空間係為非常靠近下表面118，以使得平衡裝置602a被拉出時可與下表面118幾乎形成一平整的表面。而亦可以是在下表面118上有一容納空間，而平衡裝置602a係為填補此容納空間以使平衡裝置602a與下表面118形成一平整的表面。不管為何種設計，如熟習該項技藝者可以輕易知曉，在容納空間中需配置有一軌道(未繪示)，以使平衡裝置602a可以很輕易的被拉出與推入。平衡裝置602a與602b之配置係為配置於下表面118的相對邊，且係為靠近下表面118之 角落的位置，而其數量在此係以兩個為例作說明，但實際數量自當不以此為限。其中，平衡裝置602a與602b係為用於當圖1之投影機本體104升起時，為避免投影機100因其高度過高而導致重心不穩的平衡裝置。因此，平衡裝置602a與602b之面積大小以及突出於下表面118之面積為何，則均視投影機本體104所能升起之高度而定。6A and 6B are respectively a top plan view of a lower surface of a projector according to another embodiment of the present invention, and a lower surface of the projector of FIG. 6A along line BB according to an embodiment of the invention. Schematic diagram of the section. In FIG. 6B, the balancing device 602a is configurable in the thickness of the base 102, that is, an accommodation space is disposed in the thickness of the base 102 to accommodate the balance device 602a, and the accommodation space is very close to the lower surface 118 to The balancing device 602a is allowed to form a flat surface with the lower surface 118 when it is pulled out. Alternatively, there may be a receiving space on the lower surface 118, and the balancing device 602a fills the receiving space to form a flat surface between the balancing device 602a and the lower surface 118. Regardless of the design, as will be readily appreciated by those skilled in the art, a track (not shown) needs to be disposed in the receiving space so that the balancing device 602a can be easily pulled out and pushed in. The balancing devices 602a and 602b are disposed on opposite sides of the lower surface 118 and are adjacent to the lower surface 118. The position of the corner, and the number thereof is illustrated by two examples, but the actual number is not limited to this. Wherein, the balancing devices 602a and 602b are balance devices for avoiding the instability of the center of gravity of the projector 100 due to its height being too high when the projector body 104 of FIG. 1 is raised. Therefore, the size of the balancing devices 602a and 602b and the area of the lower surface 118 are both dependent on the height at which the projector body 104 can be raised.
請參照圖7A，其繪示依照本發明又一實施例之一種投影機未旋轉時之側面透視圖。在圖7A中，投影機700包括底座702、投影機本體704與支撐臂708。在本實施例中，底座702係為用來與桌面或配置放的物品作接觸，且係為於其上方。而支撐臂708係與底座702於樞接點706的地方作樞接，支撐臂708與投影機本體704於樞接點710的地方作樞接。其中，上述之樞接方式可以例如是貫孔鎖固方式或是圓球包覆方式(如中華民國公告號第M341614號第2圖所示)。舉例來說，而貫孔鎖固方式係為在支撐臂708上有貫穿支撐臂708之一貫孔(靠近樞接點706之位置)，然後再利用一ㄇ字形的固定片將支撐臂708的第一端固定於底座702上。Please refer to FIG. 7A, which is a side perspective view of a projector when it is not rotated according to still another embodiment of the present invention. In FIG. 7A, projector 700 includes a base 702, a projector body 704, and a support arm 708. In this embodiment, the base 702 is used to make contact with the table top or the placed item, and is above it. The support arm 708 is pivotally connected to the base 702 at the pivot point 706, and the support arm 708 is pivotally connected to the projector body 704 at the pivot point 710. The pivoting manner may be, for example, a through-hole locking method or a ball wrapping method (as shown in FIG. 2 of the Republic of China Announcement No. M341614). For example, the through hole locking method has a consistent hole (close to the pivot point 706) through the support arm 708 on the support arm 708, and then the support arm 708 is replaced by a U-shaped fixing piece. One end is fixed to the base 702.
投影機本體704上係至少包括一投影單元716，此投影單元716係為輸出影像至投影布幕、牆壁或白板上，以供使用者觀看。在本實施例中，投影機本體704還包括各種投影機700應具有之單元，因其非本案之重點，故在此忽略未述。The projector body 704 includes at least one projection unit 716 for outputting images to a projection screen, a wall or a whiteboard for viewing by a user. In the present embodiment, the projector body 704 further includes units that the various projectors 700 should have. Since it is not the focus of the present invention, it is omitted here.
請參照圖7B，其繪示依照本發明又一實施例之一種投影機旋轉後之側面透視圖。在圖7B中，投影單元716與支撐臂708之位置係與圖7A不同，其原因在圖7B係為圖7A之投影機被旋轉180度後的結果。在圖7A與7B中，投影機本體704不必如上述之圖2一樣得在投影機本體104被升起後才能做水平旋轉。在圖7B中，投影機本體704可在與底座702做接觸、些微接觸或有些許空隙的情況下做旋轉。因此，投影機本體704作旋轉時係以支撐臂708與底座702之樞接點706為中心，再利用支撐臂708的可旋轉性而帶動投影機本體704作旋轉。Please refer to FIG. 7B, which is a side perspective view of a projector after being rotated according to still another embodiment of the present invention. In Fig. 7B, the position of the projection unit 716 and the support arm 708 is different from that of Fig. 7A for the reason that Fig. 7B is the result of the projector of Fig. 7A being rotated by 180 degrees. In FIGS. 7A and 7B, the projector body 704 does not have to be horizontally rotated after the projector body 104 is raised as in FIG. 2 described above. In FIG. 7B, the projector body 704 can be rotated in contact with the base 702 with slight contact or slight clearance. Therefore, when the projector body 704 rotates, the projector body 704 is rotated by the rotatability of the support arm 708 centered on the pivot point 706 of the support arm 708 and the base 702.
另外，支撐臂708亦可作垂直方向的轉動，因此支撐臂708作垂直轉動時，將同時改變投影機本體704與底座702之間的距離。以圖7A為例，當支撐臂708向右作垂直轉動時，投影機本體704將由原本與底座702是接觸的關係改變為遠離底座702，且當支撐臂708與底座702之間的夾角為90度時，投影機本體704與底座702的距離最遠。若支撐臂708與底座702之間的夾角為90度後，支撐臂708持續向右轉動時，則投影機本體704與底座702之間的距離將慢慢減少，最後可以成為如圖7B之所示。In addition, the support arm 708 can also be rotated in a vertical direction. Therefore, when the support arm 708 is rotated vertically, the distance between the projector body 704 and the base 702 will be changed at the same time. Taking FIG. 7A as an example, when the support arm 708 is rotated vertically to the right, the projector body 704 is changed from being in contact with the base 702 to be away from the base 702, and when the support arm 708 and the base 702 are at an angle of 90. At the time, the projector body 704 is the farthest from the base 702. If the angle between the support arm 708 and the base 702 is 90 degrees, and the support arm 708 continues to rotate to the right, the distance between the projector body 704 and the base 702 will gradually decrease, and finally can be as shown in FIG. 7B. Show.
綜上所述，在本發明之投影機因具有伸縮臂結構，因此投影機可以原地作升降，因此使用者可以在不移動投影機之情況下調整投影機之高度。另外，投影機在升起後，還可作旋轉，所以能具有更高的便利性。In summary, since the projector of the present invention has a telescopic arm structure, the projector can be raised and lowered in place, so that the user can adjust the height of the projector without moving the projector. In addition, the projector can be rotated after being raised, so that it can be more convenient.
