Description

Technical Field

[0001] This invention relates to a peripheral device for computer 3C products, and more particularly to a clamping device and a lighting device suitable for displays such as computer screens. Background Technology

[0002] See Figures 1 to 3 Chinese patent CN 107238015 A discloses a conventional lighting device. Because this lighting device is suitable for hanging / clamping on the top of a desktop monitor, it is commonly known as a screen hanging light or screen clamp light. The lighting device includes a rod-shaped lighting assembly 11 and a clamping device 12 for mounting the lighting assembly 11 on the top of the monitor.

[0003] The clamping device 12 includes a support element 121 suitable for mounting on the top of the display, a mounting element 122 pivotally connected to the front end of the support element 121 and having a C-shaped cross-section for mounting the lighting device 11, a pivot element 123 that is higher in the front and lower in the back and pivotally connected to the rear end of the support element 121 and extending downward and backward, a counterweight element 124 disposed in the pivot element 123, and an elastic element 125 disposed between the support element 121 and the pivot element 123.

[0004] The counterweight element 124 is mounted on the lower rear end of the pivot element 123. The elastic element 125 is a torsion spring that passes through the pivot point between the support element 121 and the pivot element 123 and provides an elastic force that brings the support element 121 and the pivot element 123 closer together.

[0005] Although the counterweight 124 can drive the pivot 123 to swing downwards, the direction of gravity is only downwards and not forwards. Therefore, it cannot further drive the pivot 123 to push forward against the back of the display. The elastic element 125 is needed to provide elastic force to bring the support element 121 and the pivot 123 closer together so that the clamping device 12 can be stably clamped on the top of the display, thereby allowing the lighting device 11 to be installed on the top of the display through the clamping device 12.

[0006] The drawback of this existing lighting fixture is that it requires a force to resist the elastic element 125 before it can be installed on top of the display, which is slightly inconvenient. Furthermore, there is a concern that the elastic element 125 may lose its elasticity over time, which also needs improvement. Therefore, a design that eliminates the need for the elastic element 125 might solve the problems arising from its use. Summary of the Invention

[0007] One object of the present invention is to provide a clamping device suitable for displays that overcomes at least one disadvantage of the prior art.

[0008] The present invention provides a clamping device suitable for mounting a lighting device on a display, comprising a support element suitable for being disposed at the top of the display, a mounting element assembled at the front end of the support element, and a pivot element. The mounting element is suitable for mounting the lighting device so that the lighting device illuminates the front area of ​​the display. The pivot element includes a pivot portion pivotally connected to the rear end of the support element, a support portion lower than the pivot portion and suitable for abutting against the back of the display, and a counterweight portion higher than the pivot portion and heavier than the support portion. Under the action of gravity, the counterweight portion can pivot forward with the pivot portion as a fulcrum, thereby abutting against the back of the display.

[0009] The clamping device of the present invention has a support portion that extends in a curved manner with its convex surface facing forward and its concave surface facing backward. The clamping device also includes an anti-slip element disposed on the convex surface of the support portion and abutting against the back of the display.

[0010] The clamping device of the present invention includes an assembly block portion mounted on the front end of the support element, and two extension arms portion spaced apart from each other and extending upward from the top of the assembly block portion, the extension arms portion being adapted to cooperate in supporting the lighting device.

[0011] The clamping device of the present invention has each extended arm that bends and extends with its convex surface facing upward and its concave surface facing downward, and includes a connecting section connecting the assembly block and a curved section opposite to the connecting section, the curved section being adapted to cooperate in supporting the lighting device, and each of the curved sections having a toothed surface at its top end adapted for the lighting device to be engaged.

[0012] The clamping device of the present invention has an assembly block that protrudes downward from the support element and can cooperate with the abutment portion of the pivot element to abut against the front and back of the display respectively.

[0013] The clamping device of the present invention further includes a counterweight element installed in the counterweight part.

[0014] Another object of the present invention is to provide a lighting device suitable for a display that overcomes at least one disadvantage of the prior art.

[0015] The present invention relates to a lighting device suitable for mounting on a display, comprising a clamping device and a lighting device. The clamping device includes a support element suitable for being disposed at the top of the display, a mounting element assembled at the front end of the support element, and a pivot element pivotally connected to the rear end of the support element. The pivot element includes a pivot portion pivotally connected to the rear end of the support element. The lighting device is mounted on the mounting element and is suitable for illuminating the front area of ​​the display. The pivot element also includes a support portion lower than the pivot portion and suitable for supporting against the back of the display, and a counterweight portion higher than the pivot portion and heavier than the support portion. Under the action of gravity, the counterweight portion, with the pivot portion as a fulcrum, pivots the support portion opposite to the counterweight portion forward, thereby supporting against the back of the display.

[0016] The lighting device of the present invention has a support portion that bends and extends with its convex surface facing forward and its concave surface facing backward. The clamping device also includes an anti-slip element disposed on the convex surface of the support portion and abutting against the back of the display.

[0017] The lighting device of the present invention includes an assembly block portion mounted on the front end of the support element, and two extension arms portion spaced apart from each other and extending upward from the top of the assembly block portion, the extension arms portion cooperating to support the lighting device.

[0018] In the lighting device of the present invention, the assembly block protrudes downward from the support element and can cooperate with the abutment portion of the pivot element to abut against the front and back of the display respectively.

[0019] The lighting device of the present invention includes a lighting element and a locking element assembled on the lighting element. The locking element includes a neck block portion that is locked between the extension arms and a head block portion whose left and right width is greater than the left and right distance between the extension arms.

[0020] The lighting device of the present invention includes an extension arm that bends and extends with its convex surface facing upward and its concave surface facing downward, and includes a connecting section connecting the assembly block and a curved section opposite to the connecting section. The curved sections cooperate to support the lighting device, and each of the curved sections forms a toothed surface at its top. The head block includes a central section connecting the neck block and side wing sections protruding from the central section on the left and right. Each side wing section is located above its respective curved section, and its bottom has a protrusion that extends laterally and engages with its respective toothed surface.

[0021] The lighting equipment of the present invention further includes a counterweight element installed in the counterweight part.

[0022] The advantages of this invention are as follows: the clamping device, by designing that the counterweight is higher than the pivot and the support and is heavier than the support, allows the counterweight to cause the support to pivot forward under the action of gravity and support the back of the display. This allows gravity to replace elastic force, eliminating the need for elastic elements to provide elastic force to clamp the display, and provides consumers with another product option with a different structure, promoting healthy competition and development in the industry.

[0034] See Figures 4 to 6The first embodiment of the present invention, applicable to a clamping device and lighting equipment for a display, is a lighting equipment suitable for mounting on a display 2. In this first embodiment, the display 2 is a computer screen used to connect to a computer host to display computer images, but it is not limited thereto; any display device in a panel shape is applicable. For example, a display 2 used as a television or advertising billboard, etc.

[0035] See Figures 5 to 7 The first embodiment includes a clamping device 3 suitable for mounting on the display 2, and a lighting device 4 mounted on the clamping device 3.

[0036] The clamping device 3 includes a support element 31 suitable for mounting on the top of the display 2, a mounting element 32 assembled on the front end of the support element 31, a pivot element 33 pivotally connected to the rear end of the support element 31, an anti-slip element 34 mounted on the pivot element 33, and a counterweight element 35 mounted in the pivot element 33.

[0037] The support element 31 includes a flat bottom surface 311 (see...). Figure 5 The support element 31 has a flat bottom surface 311 and an upwardly curved top surface 312. Since the top of most current displays 2 is a flat surface extending horizontally, the flat bottom surface 311 of the support element 31 will facilitate the placement of the support element 31 at the top of the display 2. The support element 31 also includes two snap-fit ​​blocks 313 located at the front end and spaced apart from each other.

[0038] The mounting element 32 is made of plastic and includes an assembly block portion 321 located at the front end of the support element 31 with its left and right ends snapped between the snap-fit ​​blocks 313, and two extension arms 322 that are spaced apart from each other and bend upward from the top of the assembly block portion 321.

[0039] The assembly block 321 is integrally connected to the extension arm 322 with a continuous curvature, and the lower half is as follows: Figure 5 The surface shown is suitable for contacting the front of the display 2.

[0040] Each extension arm 322 extends in a curved manner with its convex surface facing upward and its concave surface facing downward, and includes a connecting segment 323 connecting the assembly block 321, and a curved segment 324 opposite to the connecting segment 323.

[0041] Each of the connecting segments 323 forms a through hole 325 extending from front to back. Each of the curved segments 324 extends in an arc, and a toothed surface 326 is formed at its apex on the inner side facing another curved segment 324 (see additional reference). Figure 8Each curved segment 324 also has a positioning protrusion 327 protruding toward another curved segment 324 on its inner side (see...). Figure 7 ).

[0042] The pivot element 33 includes a pivot portion 331 that pivots to the rear end of the support element 31, a support portion 332 that is lower than the pivot portion 331 and is adapted to abut against the back of the display 2, and a counterweight portion 333 that is higher than the pivot portion 331.

[0043] The pivot portion 331 and the abutment portion 332 are integrally connected with a continuous curvature. The abutment portion 332 extends with its convex surface facing forward and its concave surface facing backward, and is supported against the back of the display 2 by the anti-slip element 34. The counterweight portion 333 is integrally connected to the pivot portion 331 and is located at opposite ends of the pivot portion 331, respectively, as the abutment portion 332. The counterweight portion 333 is generally hollow cylindrical and defines a cylindrical insertion space 334 that extends laterally. The inner surface of the counterweight portion 333 has a plurality of stop protrusions 335 that protrude into the insertion space 334.

[0044] The anti-slip element 34 is disposed on the convex surface of the support portion 332 and is pushed forward by the support portion 332 to abut against the back of the display 2. The anti-slip element 34 includes an anti-slip surface 341 with a horizontal stripe structure (see...). Figure 7 ).

[0045] The counterweight element 35 is cylindrical and is fitted into the fitting space 334 of the counterweight part 333, so that the counterweight part 333 is heavier than the support part 332. In the fitting space 334, the counterweight element 35 is limited by the stop protrusion 335 and will not move arbitrarily relative to the counterweight part 333.

[0046] The lighting device 4 includes a generally cylindrical lighting element 41 (see...). Figure 4 ), and a locking element 42 assembled on the lamp element 41 and capable of engaging between the extension arm 322 of the mounting element 32.

[0047] The locking element 42 is screwed and fixed to the central top part of the lamp element 41. It is generally T-shaped and includes a neck block 421 that is locked between the extension arms 322, and a head block 422 whose left and right width is greater than the left and right width of the neck block 421 and greater than the left and right distance between the extension arms 322.

[0048] The head portion 422 includes a central segment 423 connecting the neck portion 421 (see...). Figure 6 ), and the left and right wing sections 424 protruding from opposite ends of the central section 423 (see Figure 6Each wing segment 424 is located above and supported by its respective curved segment 324, and its bottom has a laterally extending protrusion 425 that engages with its respective tooth surface 326 (for further reference). Figure 8 ).

[0049] In this first embodiment, the lamp device 4 is first installed on the clamp device 3, and then the clamp device 3 is clamped on the top of the display 2.

[0050] First, since the mounting element 32 of the clamping device 3 is made of plastic and has a slight deformability, as long as the extension arm 322 of the mounting element 32 is opened back-to-back, the neck block 421 of the locking element 42 of the lamp device 4 is allowed to enter between the extension arms 322 through the positioning protrusion 327. When the extension arm 322 is released, the positioning protrusion 327 can cooperate to limit the neck block 421 between the extension arms 322. The side wing section 424 of the locking element 42 will then... Figure 5 The lamp device 4 is schematically supported by the curved section 324 of the extended arm 322 of the mounting element 32, thereby enabling the lamp device 4 to be mounted on the clamping device 3.

[0051] Next, the flat bottom surface 311 of the support element 31 is pressed against the top of the display 2, and the rear side of the assembly block portion 321 of the mounting element 32 is pressed against the top front of the display 2. Then, the support portion 332 of the pivot element 33 is pressed against the back of the display 2. In this way, the counterweight portion 333, which is fitted with the counterweight element 35, will provide a support portion 332 opposite to the counterweight portion 333 and the counterweight element 35 under the action of gravity. With the pivot portion 331 as the fulcrum, it will pivot forward and press against the back of the display 2, so that the clamping device 3 can be clamped at the top of the display 2. After installation, since the lamp element 41 of the lamp device 4 is supported above and in front of the display 2 by the clamping device 3, the lamp device 4 can illuminate the front area of ​​the display 2.

[0052] See Figure 6 , 8 9. If the user needs to adjust the lighting range, because the curved section 324 of the extended arm 322 extends in an arc and the lamp element 41 is rod-shaped, the user can adjust the lighting range as needed. Figure 8 , 9The lamp element 41 is rotated relative to the extension arm 322, thereby changing the illumination range. The protrusion 425 of each of the side wing segments 424 of the locking element 42 can engage with the corresponding tooth groove of the toothed surface 326 of the respective extension arm 322 after the lamp element 41 changes position, thus positioning the locking element 42 and the lamp element 41 and preventing the lamp element 41 from rotating arbitrarily relative to the clamping device 3.

[0053] See Figure 10 The second embodiment of the present invention, applicable to the clamping device for displays and the lighting equipment, is similar to the first embodiment, except that the counterweight element 35 is omitted (see...). Figure 5 Furthermore, the counterweight 333 omits the insertion space 334 (see...). Figure 5 ) and the aforementioned stop protrusion 335 (see Figure 5 Furthermore, the counterweight 333 is integrally formed into a solid cylindrical shape and integrally connected to the pivot 331.

[0054] In this second embodiment, although the counterweight 333, the pivot 331, and the support 332 are integrally formed and made of the same material, the counterweight 333 is larger in volume than the pivot 331 and the support 332. Therefore, the counterweight 333 is heavier than the support 332, thus producing the same effect as in the first embodiment, causing the support 332 to pivot forward and support the back of the display 2.

[0055] In summary, the advantages of the clamping device for displays and lighting equipment of the present invention are as follows: the clamping device 3, by designing that the counterweight 333 is higher than the pivot 331 and the support 332 and heavier than the support 332, allows the counterweight element 35 to cause the support 332 to pivot forward under the action of gravity and support the back of the display 2. Thus, gravity can replace elastic force, eliminating the need for elastic force provided by elastic elements to clamp the display 2. It also provides consumers with an alternative structure that differs from the existing product structure, promoting healthy competition and development in the industry.
