Description

Technical Field

[0001] The invention relates to a support frame, in particular to a support frame which can rotate left and right. Background Art

[0002] Generally, a display, such as a computer monitor, is placed on a desktop via a tripod to facilitate viewing by the user. However, many tripods on the market do not have the function of swivel, which makes it inconvenient to adjust the angle of the display. Some tripods have the function of swivel, and the swivel mechanism is set at the bottom of the tripod, but such swivel mechanism usually takes up more space or is more complicated, resulting in a thicker bottom of the tripod, which is not conducive to thinning the product. Some other tripods set the swivel mechanism at the neck of the tripod (i.e., the support component of the tripod between the display and the bottom of the tripod), but the mechanism is exposed and not beautiful. Summary of the invention

[0003] The object of the present invention is to provide a support frame which has the function of left-right rotation, simple structure and light, thin and beautiful appearance.

[0004] A support frame of the present invention includes a base, a rotating column, a gasket and a positioning member. The base includes a bottom and a supporting column. The supporting column is fixed to the bottom. The outer peripheral surface of the supporting column is recessed to form a positioning groove. The rotating column is covered with the supporting column and has a recess, and the recess faces the bottom. The gasket is arranged in the recess and is located between the rotating column and the bottom. The positioning member is arranged between the positioning groove and the rotating column to prevent the rotating column from moving along the gravity direction. The rotating column is suitable for rotating relative to the bottom and the supporting column.

[0005] In one embodiment of the present invention, the support column comprises a supporting body and a fixing portion connected to each other. The fixing portion is fixed to the bottom. The supporting body extends toward the rotating column and is covered by the rotating column.

[0006] In one embodiment of the present invention, the support column overlaps with the rotating column in the gravity direction.

[0007] In one embodiment of the present invention, the bottom has a limiting groove. The rotating column includes a main column portion and a protruding portion. The protruding portion is arranged at one end of the main column portion. The protruding portion is suitable for moving in the limiting groove.

[0008] In one embodiment of the present invention, the support frame further comprises an elastic member, which is disposed between the gasket and the bottom to abut against the gasket.

[0009] In one embodiment of the present invention, the rotating column has a through hole. The through hole is aligned with the positioning groove. The positioning member passes through the through hole and enters the positioning groove. The positioning groove stops the positioning member along the gravity direction.

[0010] In one embodiment of the present invention, the positioning member comprises a positioning ring. The rotating column has a clearance groove. The clearance groove is located opposite to the positioning groove. The positioning ring is disposed in the positioning groove and the clearance groove and stops the rotating column along the gravity direction.

[0011] Based on the above, in the support frame of the present invention, the base includes a bottom and a support column, the rotating column is covered on the support column, and the gasket is arranged in the recess of the rotating column and is located between the rotating column and the bottom. As a result, the weight of the rotating column forms a positive force on the gasket, and this positive force brings a moderate friction force between the rotating column and the gasket, so that the rotating column on the gasket can rotate well relative to the bottom and the support column, and the limited space of the support frame is utilized to realize the function of left and right rotation. In addition, the support frame of the present invention has a simple rotating mechanism and requires few components, which is not only conducive to the thinning of the base, but also the rotating mechanism is located inside, which also contributes to the beautiful appearance.

[0041] Figure 1 is a schematic diagram of a support frame according to an embodiment of the present invention. Figure 1 The support frame 10 of the present embodiment can be disposed on a flat surface such as a desktop to support an electronic device such as a computer monitor, but the application objects of the support frame 10 are not limited thereto.

[0042] In this embodiment, the support frame 10 includes an appearance member 140, a base 100, a rotating column 110 and a gasket 120. The appearance member 140 is fixed to the rotating column 110. The base 100 includes a bottom 102 and a support column 104. The support column 104 is fixed to the bottom 102 by riveting, for example, and the bottom 102 can be placed on a plane.

[0043] The support column 104 includes a supporting body 1041 and a fixing portion 1042 connected to each other. The supporting body 1041 is columnar and extends from the fixing portion 1042 toward the rotating column 110. The fixing portion 1042 is fixed to the bottom 102 so that the support column 104 is immovable relative to the bottom 102.

[0044] The rotating column 110 is, for example, a columnar metal piece, which can be rotatably covered on the supporting body 1041 of the supporting column 104. The supporting column 104 overlaps with the rotating column 110 in the gravity direction (i.e., the negative Y direction), and the rotating column 110 and the supporting body 1041 have the same central axis M, so that the rotating column 110 rotates relative to the supporting column 104 with the central axis M as the rotation axis.

[0045] The rotating column 110 has a recess 112, which faces the bottom 102 and surrounds the supporting body 1041 to accommodate the gasket 120. The gasket 120 is disposed in the recess 112 and is located between the rotating column 110 and the bottom 102, and is in contact with the rotating column 110 and the bottom 102. The gasket 120 is, for example, a polyoxymethylene (POM) plastic material with wear-resistant properties, but the material of the gasket 120 is not limited thereto.

[0046] An electronic device such as a computer monitor can be assembled on the upper side of the rotating column 110. When the support frame 10 is used, since the rotating column 110 can be rotatably covered on the supporting body 1041 of the supporting column 104, the user only needs to apply a slight force to the electronic device to rotate the rotating column 110 relative to the bottom 102 and the supporting column 104. Further, the weight of the rotating column 110 generates a positive force on the gasket 120, and this positive force can bring a moderate friction force between the rotating column 110 and the gasket 120, so that the rotating column 110 on the gasket 120 can rotate well relative to the bottom 102 and the supporting column 104, thereby achieving the effect of rotating the support frame 10 left and right.

[0047] Many known tripods do not have the function of rotating left and right, that is, the function of rotating around the neck of the display (i.e., the supporting component between the display and the bottom of the tripod) as the axis of rotation. Although some tripods have this function, the rotating mechanism located at the bottom of the tripod usually takes up more space or is more complicated, resulting in a thicker bottom of the tripod, which is not conducive to thinning the product. Some other tripods have the rotating mechanism set at the neck, but it is often exposed at the neck and is not beautiful.

[0048] In contrast, the support frame 10 of the present embodiment utilizes a coaxially arranged rotating column 110 to cover the supporting column 104, and the design that the normal force generated by the weight of the rotating column 110 is converted into a friction force effectively utilizes the limited space in the support frame 10 to set the rotating mechanism, thereby achieving a smooth left-right rotation effect. At the same time, the structure of the support frame 10 is simple, and the number of components required is small, which is not only conducive to the thinning of the base 100, but also the rotating mechanism is hidden in the support frame 10, which can also enhance the appearance of the product.

[0049] In this embodiment, the support frame 10 further includes a positioning member 130. The positioning member 130 is disposed between a positioning slot A of the support column 104 and the rotating column 110 to prevent the rotating column 110 from moving along the gravity direction (ie, the negative Y direction).

[0050] Specifically, the outer peripheral surface CS of the supporting body 1041 of the supporting column 104 is recessed to form a positioning groove A, and the positioning groove A surrounds the supporting body 1041. The rotating column 110 has a through hole O, and the through hole O is aligned with the positioning groove A.

[0051] The positioning member 130 is, for example, a latch pin, which can be inserted into the through hole O from the outside of the rotating column 110, and at least a portion of the positioning member 130 enters the positioning groove A. Therefore, the positioning groove A can stop the positioning member 130 along the gravity direction to prevent the rotating column 110 from separating from the supporting column 104, and the positioning member 130 will not affect the rotation of the rotating column 110.

[0052] Figure 2A is a schematic diagram of a support frame according to another embodiment of the present invention. Figure 2B yes Figure 2A Schematic cross-sectional view of the support frame along the PP section line. Figure 2A The illustrated embodiment and Figure 1 The main difference of the embodiment shown is that Figure 2A The support frame 10a has a limiting groove B to appropriately limit the rotation range of the rotating column 110a.

[0053] Specifically, the bottom 102a has a limiting groove B, which is located outside the supporting body 1041. The rotating column 110a includes a main column portion 114 and a protrusion 116, which is disposed at one end of the main column portion 114 and protrudes into the limiting groove B.

[0054] When the rotating column 110a rotates relative to the bottom 102a and the supporting column 104, the protruding portion 116 can Figure 2B As shown, the rotating column 110 a moves in the limiting groove B, thereby appropriately limiting the rotation range of the rotating column 110 a.

[0055] In this embodiment, there are two protrusions 116 , but the number of the protrusions 116 is not limited thereto, as long as they can be matched with the limiting grooves B.

[0056] In addition, if Figure 2B As shown, the limiting grooves B of this embodiment are two arc grooves, which are respectively located on opposite sides of the supporting body 1041, but the number, size and distribution position of the limiting grooves B are not limited thereto, as long as the rotation range of the rotating column 110a can be limited according to actual design requirements. The rest of the configuration of the support frame 10a is the same or similar to the aforementioned support frame 10, and will not be repeated here.

[0057] Figure 3 is a schematic diagram of a support frame according to another embodiment of the present invention. Figure 3 The illustrated embodiment and Figure 2A The main difference of the embodiment shown is that Figure 3 The support frame 10 b further includes an elastic member 150 to adjust the friction between the rotating column 110 a and the gasket 120 .

[0058] Specifically, the elastic member 150 has elastic force, such as a spring or a disc-shaped spring. The elastic member 150 is located in the recess 112 of the rotating column 110a and is disposed between the gasket 120 and the bottom 102a. Through its own elastic force, the elastic member 150 can push against the gasket 120 in the direction opposite to the direction of gravity (i.e., the Y direction) to increase the positive force between the rotating column 110a and the gasket 120, thereby increasing the friction between the rotating column 110a and the gasket 120. Therefore, even if a lighter electronic device is assembled on the support frame 10b, the support frame 10b can still rotate left and right well. The rest of the configuration of the support frame 10b is the same or similar to the aforementioned support frame 10a, and will not be repeated here.

[0059] Figure 4 is a schematic diagram of a support frame according to another embodiment of the present invention. Figure 5 yes Figure 4 Schematic diagram of the support column and positioning ring. Figure 4 The illustrated embodiment and Figure 3 The main difference of the embodiment shown is that Figure 4 The support frame 10c has different positioning methods.

[0060] For more information, see Figure 4 and Figure 5 The inner wall surface of the rotating column 110c is recessed to form a clearance groove C, which surrounds the inner wall surface and is aligned with the positioning groove A. The outer peripheral surface CS of the supporting body 1041c is recessed to form the positioning groove A, which surrounds the supporting body 1041c.

[0061] The positioning member 130 of this embodiment is a positioning ring 132, and the positioning ring 132 is disposed in the positioning groove A and the clearance groove C. Therefore, the positioning ring 132 can stop the rotating column 110c along the gravity direction (i.e., the negative Y direction) to prevent the rotating column 110c from separating from the supporting column 104c. The rest of the configuration of the support frame 10c is the same or similar to the aforementioned support frame 10b, and will not be repeated here.

[0062] In summary, in the support frame of the present invention, the base includes a bottom and a support column, the rotating column is covered on the support column, and the gasket is arranged in the recess of the rotating column and is located between the rotating column and the bottom. Therefore, the weight of the rotating column forms a positive force on the gasket, and this positive force brings a moderate friction force between the rotating column and the gasket, so that the rotating column on the gasket can rotate well relative to the bottom and the support column, and the limited space of the support frame is utilized to realize the function of left and right rotation. In addition, the support frame of the present invention has a simple rotating mechanism and requires few components, which is not only conducive to the thinning of the base, but also the rotating mechanism is located inside, which also contributes to the beautiful appearance.

[0063] In addition, in the support frame of the present invention, an elastic member can be arranged between the gasket and the bottom so that the elastic member abuts against the gasket, thereby increasing the friction between the rotating column and the gasket. In this way, even if the display device assembled on the support frame is too light, the support frame can still rotate left and right well.

[0064] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Those skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the appended claims.
