Description

Adjustable support device

The invention relates to a support device, and more particularly to an adjustable support device.

Generally, the support device has a design fixed by a support structure, and a design with an adjustable support structure. In the latter case, the object can be fixed to the support device with more support patterns. In the case of display brackets that are currently commonly equipped with setting adjustments, they typically provide a single degree of freedom adjustment, such as height adjustment. The height adjustment mechanism is usually constituted by a slide rail provided on the pillar, a sliding member sliding on the slide rail, and a constant force spring for providing a fixed supporting force, and the structure is complicated. For other degrees of freedom adjustment, more than a fixed mechanism connected to the sliding member is provided with a rotatable mechanism, such as a pitch adjustment. When the support frame needs to provide more adjustment freedom, it is necessary to set more rotatable mechanisms, so that the entire support frame structure is more complicated.

In view of the problems in the prior art, it is an object of the present invention to provide an adjustable support device that can be easily constructed using only a few members to provide adjustment of three degrees of freedom of an object secured thereto.

The adjustable support device of the present invention comprises a base, a support column, a connecting member and a fixing bracket. The support column is connected to the base and extends along a first direction, and the connecting member is adjustable along the first direction The base is disposed on the support column and rotatable relative to the base through the support column, and the fixed frame is pivotally connected to the connecting member in a second direction. Thereby, the fixing frame can have three adjustment degrees of freedom with respect to the base (ie, linear movement adjustment along the first direction, rotation adjustment in the second direction as a rotation axis, and transmission through the support column relative to The rotation of the base is adjusted).

Compared with the prior art, the present invention can be shaped by simply combining a few of the aforementioned components. In this adjustable support device, the adjustable support device has a simple structure, but can still provide three degrees of freedom adjustment of the object fixed to the holder. In addition, the simple design of the adjustable support device of the present invention also contributes to reducing the manufacturing cost and making it more widely applicable to the support of various objects.

The holder 544 can be stopped at a corresponding position relative to the support post 52 without sliding downward (toward the base 10). In use, the above-mentioned up and down movement adjustment can be achieved by engaging the holding member 544 into the different annular groove 52d.

In this embodiment, the holding member 544 is caught in the annular groove 52d in the natural state, and the holding member 544 can be operated to terminate the holding member 544 by the end 544a (projecting from the connecting body 542). The groove 52d is slidable up and down with respect to the support post 52 together with the connecting body 542. In practice, other drive mechanisms are also available to cause the catch 544 to snap into and out of the annular groove 52d. In addition, in the present embodiment, when the holding member 542 is disposed, that is, when the connecting body 542 is stopped at a corresponding position in the first direction D1 with respect to the supporting post 52 via the holding member 544, the connecting body 542 still has a relative position. Rotating the support column 52 to achieve the aforementioned left and right rotation adjustment; wherein the angle range in which the connecting body 542 can be rotated is limited by the width of the slit 52b, so that the width of the slit 52b can be designed to achieve the desired width. The range of angles that can be rotated, in general, the need for 360 degrees of rotation around the support column 52 is limited, so this embodiment is still quite practical. As for the aforementioned pitch rotation The whole is still realized by the pivoting of the fixing frame 16 and the connecting body 542 in the second direction D2.

In this embodiment, logically, the holding member 544 is still considered to be located between the connecting body 542 and the base 10, so that the holding member 544 can generate the blocking connecting body 542 to prevent it from sliding down. In fact, in the embodiment, the holding member 544 is located inside the structure of the connecting body 542, so that the holding member 544 can also prevent the connecting body 542 from moving upward.
