Abstract

A foldable rotatable bracket includes a fixed seat, a rotating seat, a rotating mechanism, a support arm and a slider. The rotating mechanism connects the fixed seat and the rotating seat, and the rotating seat rotates relative to the fixed seat by means of the rotating mechanism. The support arm has a pivoting portion pivotally connected to the rotating seat, so that the support arm pivots relative to the rotating seat and switches between a folded state and a raised state. The support arm rotates relative to the fixed seat along with the rotating seat, and the support arm has a latching member located beside the pivoting portion and moves with the pivoting portion. The slider is movably arranged on the fixed seat, and a part of the slider is penetrated through the rotating seat and is located on the moving path of the latching member. In the folded state, the latching member and the part interfere with each other to prevent the rotating seat from rotating relative to the fixed seat. In the raised state, the latching member moves away from the part to allow the support arm and the rotating seat to rotate relative to the fixed seat.

Description

Foldable rotatable stand

Technical Field

The utility model relates to a bracket, and in particular to a foldable rotatable bracket.

Background technique

With the technological advancement of electronic information equipment, modern people use televisions, computers and other information equipment for more than just watching programs or working. In addition to requiring electronic equipment to be upgraded in hardware, modern people also require software that can meet people's entertainment, education, audio and video, sound and light, games, interaction, Internet access and other functions. Therefore, today's electronic equipment has been developing in the direction of diversified functions.

Among the aforementioned functions, headphones are important information devices that satisfy people's needs. At the same time, headphones are mostly installed next to information devices (such as computer hosts or computer cases) through a hanger locked by multiple screws. However, this method is not conducive to the replacement of the hanger, because the screws may have problems such as stripping and rusting, and the hanger locked by the screws may break due to excessive force or improper pulling. In addition, information devices do not necessarily have structures that can be assembled with hangers.

More importantly, most existing racks are fixed structures. Therefore, even if the above-mentioned assembly problem is overcome, the fixed structure still occupies a large space next to the information equipment, which still causes inconvenience to the user and reduces the user's willingness to use.

Utility Model Content

The utility model provides a foldable rotatable bracket, which utilizes pivot shafts with different axial directions to enable the foldable rotatable bracket to have a folding state with a storage effect, thereby providing a stable supporting unfolding state, and further provides a non-rotatable mode and a rotatable mode for the folding state and the unfolding state.

Based on the above, the fixed seat and the rotating seat generate relative rotation along one axis through the rotating mechanism, and further allow the support arm to be pivoted to the rotating seat along another axis. In this way, the foldable rotatable bracket can be rotated along different axes to produce a folded state or a raised state and a rotation mode. More importantly, the support arm has a latch member located next to the pivoting portion to move with the pivoting portion. The foldable rotatable bracket also includes a slider arranged on the fixed seat, a portion of which passes through the fixed seat and extends to and is exposed to the rotating seat, and the portion is located on the moving path of the latch member, and in particular on the rotation path of the latch member with the support arm.

Accordingly, in the folded state, the support arm is superimposed on the rotating seat, and the latch member interferes with the slider, so that the support arm cannot rotate relative to the fixed seat by the rotating mechanism, that is, the foldable rotatable bracket is in a non-rotatable mode. In contrast, in the raised state, since the support arm is pivoted and raised relative to the rotating seat, the latch member is also moved away from the slider, so that the support arm and the rotating seat can rotate relative to the fixed seat by the rotating mechanism, that is, the foldable rotatable bracket is in a rotatable mode.

Detailed ways

FIG. 1A is a schematic diagram of a foldable rotatable stand according to an embodiment of the present invention. FIG. 1B is a side view of the foldable rotatable stand of FIG. 1A. FIG. 2A illustrates another state of the foldable rotatable stand of FIG. 1A. FIG. 2B is a side view of the foldable rotatable stand of FIG. 2A. FIG. 3 illustrates another state of the foldable rotatable stand of FIG. 1A. Please refer to FIG. 1A, FIG. 2A and FIG. 3. In the present embodiment, a foldable rotatable stand 100 (hereinafter referred to as stand 100) includes a support arm 110, a stop arm 120 and a base assembly 130. The base assembly 130 includes a fixed seat 132 and a rotating seat 131, and the rotating seat 131 can rotate relative to the fixed seat 132 about an axis CX1. Furthermore, the support arm 110 has a bearing portion 111 and a pivoting portion 112 that are opposite to each other, wherein the pivoting portion 112 is pivotally connected to the rotating seat 131, so that the support arm 110 can rotate relative to the rotating seat 131 about an axis CX2. In this way, as shown in the current related figures, the bracket 100 can be switched between the folded state shown in FIG. 1A and the raised state shown in FIG. 2B , and in the raised state, the support arm 110 and the rotating base 131 can also rotate about the axis CX1 relative to the fixed base 132. In this embodiment, the axis CX1 and the axis CX2 are different from each other and are substantially orthogonal to each other.

Please refer to FIG. 1B and FIG. 2B again. In this embodiment, the bracket 110 is suitable for being assembled on the platform 200 with its base assembly 130, so that when it is converted into the raised state, the bearing portion 111 of the support arm 110 can be mounted or placed on the objects B1 and B2 to produce the object storage effect. When it is converted into the folded state, the support arm 110 is stacked on the base assembly 130 and simultaneously moved closer to the platform 200 to produce the self-storage effect of the bracket 100. Here, the platform 200 can be a desktop or the aforementioned information equipment (such as a computer host or chassis), which is not limited here. At the same time, this embodiment also does not limit the means by which the bracket 100 is assembled to the platform 200.

FIG. 4A and FIG. 4B are exploded views of the foldable rotatable bracket of FIG. 1A at different viewing angles. Please refer to FIG. 4A and FIG. 4B simultaneously. In this embodiment, the base assembly 130 further includes a turntable 133, a slider 134, at least one second guide member (a pair of second guide members 135 is used as an example, but not limited thereto), at least one spring (a pair of springs 136 is used as an example, but not limited thereto), an axle member 137 and a first guide member 138. The fixed seat 132 includes a seat body 1 132a and a seat body 2 132b assembled together, wherein the seat body 1 132a is provided with an axle hole R5 and a track R4. Here, the axle member 137 is disposed in the fixed seat 132 and is substantially located between the seat body 1 132a and the seat body 2 132b, and a portion of the axle member 137 passes through the axle hole R5 and the turntable 133 and is assembled to the rotating seat 131. Furthermore, the first guide member 138 is also disposed in the fixed seat 132, and partially passes through the track R4 and the turntable 133 to be assembled to the rotating seat 131. In short, the track R4 of this embodiment is an arc track, and the shaft hole R5 is the center of the arc track. In this way, the rotating seat 131 can move along the track R4 through the first guide member 138, and drive the turntable 133 to rotate on the fixed seat 132. Here, the shaft hole R5 and the track R4 are both located in the groove R3 of the seat body 132a.

In addition, the slider 134 of this embodiment is movably disposed in the groove R2 of the fixed seat 132. Here, the groove R2 and the groove R3 are adjacent to each other and communicated. In detail, the slider 134 has two side portions S1 and S2 opposite to each other, at least one expansion hole (a pair of expansion holes K2 is used as an example, but not limited to this), a latch portion K1 located on the side portion S1, and a receiving groove K4 and a receiving column K3 located on the side portion S2. In contrast, the second guide member 135 is inserted through the expansion hole K2 and assembled to the fixed seat 132, and the spring 136 is disposed in the groove R1 and abuts between the slider 134 and the fixed seat 132.

The second guide member 135 is a stepped screw. The first stage C1 of the second guide member 135 is a smooth cylindrical surface to couple with the expanded hole K2 . The second stage C2 of the second guide member 135 is a stud to be locked into the fixing seat 132 .

FIG. 5A to FIG. 5C are exploded views of different components of the foldable rotatable bracket at different degrees. Please refer to FIG. 5A, FIG. 5B and FIG. 4A, as described above, the corresponding relationship between the fixed seat 132 and the slider 134. The slider 134 is actually exposed from the fixed seat 132, and the rotating seat 131a also has an opening 131a, whose outer contour roughly conforms to the slider 134, so that as shown in FIG. 5B, the latch portion K1 of the slider 134 and its stop groove K1a (arc-shaped concave) can be further exposed from the opening 131a. In addition, in the state shown in FIG. 5A, the spring 136 is in a state of being squeezed and deformed, and the spring 136 can provide a force F1 to push the slider 134, so that the spring 136 constantly drives the slider 134 to move toward the rotating mechanism RM (indicated in FIG. 4A).

6A and 6B are partial three-dimensional cross-sectional views of the foldable rotatable bracket in different states. Please refer to FIG. 6A and FIG. 5B and FIG. 5C first. The latch 113 of this embodiment can be regarded as a (stepped) cylinder and assembled on the pivoting portion 112 of the support arm 110. Therefore, in the folded state as shown in FIG. 6A, the latch 113 will fall into and fit into the stop groove K1a of the latch portion K1. In fact, the stop groove K1a blocks the rotatable direction of the latch 113, thereby creating a stop effect and preventing the support arm 110 from rotating about the axis CX1.

Please refer to FIG. 6A and FIG. 6B and compare with FIG. 4A. In this embodiment, the bracket 100 further includes a stopper arm 120, which has a first side 121 and a second side 122 opposite to each other, wherein the first side 121 is pivotally connected to the hollow portion 112a of the support arm 110 through a pivot axis P2, and the second side 122 is movably coupled to the rotating seat 131. In short, in the folded state, the stopper arm 120 and the support arm 110 are respectively overlapped on the rotating seat 131, and the stopper arm 120 is located in the hollow portion 112a, as shown in FIG. 6A. In the raised state, the stopper arm 120 is driven by the support arm 110, so that the second side 122 of the stopper arm 120 moves out of the hollow portion 112a, slides in the rotating seat 131, and abuts against the side away from the pivoting portion 112. At this time, the support arm 110 and the stopper arm 120 stand on the rotating seat 131 in an inclined manner. Meanwhile, the bracket 100 further includes a pair of magnetic members M1 and M2 respectively disposed on the second side 122 of the stop arm 120 and the rotating seat 131 , so that when in the lifted state, the magnetic members M1 and M2 attract each other to make the second side 122 of the stop arm 120 abut against the rotating seat 131 .

In short, when the user wants to unfold the support arm 110, he only needs to apply force to lift the support arm 110 relative to the rotating seat 131, so as to drive the stop arm 120 to switch from the state shown in FIG. 6A to the state shown in FIG. 6B, and complete the process of switching from the folded state to the lifted state. On the contrary, if the support arm 110 is to be retracted, the support arm 110 needs to be lifted first (as described above) to facilitate the separation of the magnetic elements M1 and M2 to release the locking relationship, and then the support arm 110 is lowered to move closer to the rotating seat 131 until the folded state shown in FIG. 6A is restored.

In summary, in the above-mentioned embodiment of the utility model, the fixed seat and the rotating seat generate relative rotation along one axis through the rotating mechanism, and further allow the support arm to be pivoted to the rotating seat in another axis. In this way, the foldable rotatable bracket can be rotated in different axes to produce a folded state or a lifted state and a rotation mode. More importantly, the support arm has a latch, which is located next to the pivot portion to move with the pivot portion. The foldable rotatable bracket also includes a slider arranged on the fixed seat, a portion of which passes through the fixed seat and extends to and is exposed to the rotating seat, and the portion is located on the moving path of the latch, and in particular on the rotation path of the latch with the support arm.

Accordingly, in the folded state, the support arm is overlapped on the rotating seat, and the latch interferes with the slider, so that the support arm cannot be rotated relative to the fixed seat by the rotating mechanism, that is, the foldable rotatable bracket is in a non-rotatable mode. At this time, for example, the user wants to carry the foldable rotatable bracket, so the folded state and non-rotatable characteristics can provide convenience when carrying.

In contrast, in the raised state, the support arm is pivoted and raised relative to the rotating seat, and the latch is thus moved away from the slider, so that the support arm and the rotating seat can rotate relative to the fixed seat through the rotating mechanism, that is, the foldable rotatable stand is in a rotatable mode. This is the normal use state of the foldable rotatable stand, so the raised support arm and the rotatable base assembly allow the support arm to carry (or mount) objects, and can also adjust the posture of the support arm by rotating according to the user's position.
