This application claims the priority benefit of Taiwan application serial no. 107146725, filed on Dec. 24, 2018. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The disclosure relates to a chair, and more particularly to a swing chair.
Due to changes in work styles and recreational activities, modern people spend a significant amount of time seating on chairs to handle office work, personal affairs, or play video games. In general, most conventional office chairs, computer chairs, or e-sports chairs have freedom of movement for rotation perpendicular to the ground, while some other office chairs, computer chairs, or e-sports chairs can withstand force to be leaned backward. However, to produce all of these movements, force has to be applied through the seater or others to the office chair, the computer chair, or the e-sports chair.
The disclosure provides a swing chair, which can automatically rotate around two different axes.
The swing chair of the disclosure includes a base, a seat, and a driving frame. The seat is disposed above the base. The driving frame is disposed between the base and the seat. The driving frame includes a first fixing base, a first shaft, a second fixing base, a second shaft, a first driving assembly, and a second driving assembly. The first fixing base is fixed to the base. The first shaft is rotatably connected to the first fixing base. The second fixing base is fixed to the seat. The second shaft is connected to the first shaft and the second fixing base is rotatably connected to the second shaft. The first driving assembly is configured to drive the first shaft to rotate with respect to the first fixing base. The second driving assembly is configured to drive the second fixing base to rotate with respect to the second shaft.
Based on the above, the swing chair of the disclosure can automatically rotate around two different axes to provide the seater with a better seating experience.
To make the aforementioned and other features of the disclosure more comprehensible, several embodiments accompanied with drawings are described in detail as follows.
Furthermore, the swing chair 100 includes a base 110, a seat 120, and a driving frame 130, wherein the driving frame 130 is disposed between the base 110 and the seat 120, and the seat 120 is supported by the driving frame 130 to be disposed above the base 110. The base 110 may be fixed to the ground, slide with respect to the ground or rotate around the axial direction perpendicular to the ground. The driving frame 130 is configured to drive the seat 120 to lean forward and backward or slant leftward and rightward with respect to the base 110.
In the embodiment, the driving frame 130 includes a first fixing base 131, a first shaft 132, a second fixing base 133, a second shaft 134, a first driving assembly 135, and a second driving assembly 136, wherein the first driving assembly 135 is configured to provide power to drive the seat 120 to slant leftward and rightward with respect to the base 110, and the second driving assembly 136 is configured to provide power to drive the seat 120 to lean forward and backward with respect to the base 110. On the other hand, the number of the first fixing base 131 may be two and the first fixing bases 131 are fixed to the two opposite sides of the base 110. The two opposite ends of the first shaft 132 are rotatably connected to the two first fixing bases 131 respectively. Accordingly, the number of the second fixing base 133 may be two and the second fixing bases 133 are fixed to the two opposite sides of the seat 120. The two opposite ends of the second shaft 134 are respectively connected to the two second fixing bases 133 and the two second fixing bases 133 can rotate with respect to the second shaft 134. In other words, the first shaft 132 serves as the rotational reference for the seat 120 to slant leftward and rightward with respect to the base 110, and the second shaft 134 serves as the rotational reference for the seat 120 to lean forward and backward with respect to the base 110.
From the above, the second shaft 134 is connected to the first shaft 132 and may be an integrally formed cross-shaped structure. On the other hand, the first driving assembly 135 is configured to drive the first shaft 132 to rotate with respect to the two first fixing bases 131 and the second driving assembly 136 is configured to drive the two second fixing bases 133 to rotate with respect to the second shaft 134. During the rotation of the first shaft 132 with respect to the two first fixing bases 131, the two second fixing bases 133, the second shaft 134, and the second driving assembly 136 rotate with the first shaft 132 around a first axial direction A1 to drive the seat 120 to slant leftward and rightward with respect to the base 110. In contrast, during the rotation of the two second fixing bases 133 with respect to the second shaft 134, the seat 120 rotates with the two second fixing bases 133 around a second axial direction A2 to drive the seat 120 to lean forward and backward with respect to the base 110. Furthermore, the first axial direction A1 and the second axial direction A2 are perpendicular to each other, wherein the first axial direction A1 is parallel to the first shaft 132 and the second shaft 134 is parallel to the second axial direction A2.
In the embodiment, the first driving assembly 135 includes a first motor 135a, a first driven member 135b, a first bearing 135c, and a first linking member 135d, wherein the number of the first bearing 135c may be two and the number of the first driven member 135b may be two. The two first bearings 135c are respectively fixed to the two first fixing bases 131 and the two first driven members 135b are respectively fixed to the two first bearings 135c. For example, each of the first bearings 135c is fixed to the corresponding first fixing base 131 with an outer ring, wherein each of the first driven members 135b is fixed to the outer ring of the corresponding first bearing 135c and the two opposite ends of the first shaft 132 respectively passes through the two first driven members 135b to connect to inner rings of the two first bearings 135c. In other words, each of the first driven members 135b cannot rotate with respect to the corresponding first fixing base 131, but the first shaft 132 can rotate with respect to the two first fixing bases 131 through the two first bearings 135c. From the above, the first driven member 135b is a pulley and the first linking member 135d is a belt. The first linking member 135d is coupled to one of the two first driven members 135b and a power output shaft 135e of the first motor 135a. Since the first motor 135a of the embodiment is fixed to the first shaft 132 and each of the first driven members 135b cannot rotate with respect to the corresponding first fixing base 131, the power output shaft 135e cannot drive the first linking member 135d during the operation of the first motor 135a, thereby causing the first motor 135a to produce self-rotation to drive the first shaft 132 to rotate with respect to the two first fixing bases 131 through the two first bearings 135c.
On the other hand, the second driving assembly 136 includes a second motor 136a, a second driven member 136b, a second bearing 136c, and a second linking member 136d, wherein the number of the second driven member 136b may be two and the number of the second bearing 136c may be two. The two second driven members 136b are respectively fixed to the two second fixing bases 133 and the two second bearings 136c are respectively fixed to the two second driven members 136b. For example, each of the second bearings 136c is fixed to the corresponding second driven member 136b with an outer ring and the two opposite ends of the second shaft 134 are respectively connected to inner rings of the two second bearings 136c. In other words, the two second driven members 136b are respectively connected to the second shaft 134 through the two second bearings 136c and each of the second fixing bases 133 and the corresponding second driven member 136b can rotate with respect to the second shaft 134 through the corresponding second bearing 136c.
From the above, the second driven member 136b is a pulley and the second linking member 136d is a belt. The second linking member 136d is coupled to one of the two second driven members 136b and a power output shaft 136e of the second motor 136a. During the operation of the second motor 136a, the power output shaft 136e drives the second linking member 136d to drive one of the second driven second driven members 136b to rotate with respect to the second shaft 134, thereby causing the two second fixing bases 133 to rotate with the second driven member 136b with respect to the second shaft 134.

In other words, the first shaft 132 can rotate with respect to the two first fixing bases 131 through the two first driven members 135b.
During the operation of the first motor 135a, the power output shaft 135e drives the first linking member 135d to drive one of the first driven members 135b to rotate with respect to the corresponding first fixing base 131, thereby causing the first shaft 132 to rotate with first driven member 135b with respect to the two first fixing bases 131.
Based on the above, the swing chair of the disclosure is applicable for e-sports or virtual reality games to provide the player with a better seating experience and an immersive interactive experience. For example, the swing chair may interact with the game console to cooperate with the game scenarios to automatically rotate around the two different axes or produce movements such as leaning forward and backward or slanting leftward and rightward, thereby enabling the player sitting on the swing chair to be immersed in the game. In addition, the swing chair provides power sources for movements such as leaning forward and backward or slanting leftward and rightward through the two motors respectively, so the movements such as leaning forward and backward or slanting leftward and rightward may be synchronously produced or asynchronously produced. Secondly, since the two power output shafts of the two motors are located on the same plane, the required configuration space between the seat and the base can be greatly reduced.
It may be apparent to those skilled in the art that various modifications and variations may be made to the disclosed embodiments without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure covers modifications and variations provided that they fall within the scope of the following claims and their equivalents.
