Technical Field
[0001] This utility model belongs to the field of furniture component technology, specifically relating to a tray table assembly and furniture components having the same. Background Technology
[0002] To optimize the comfort and convenience of furniture use, the industry often adds tray tables to furniture components such as chairs, sofas, and love sofas to hold small items like water cups, mobile phones, and books. However, traditional fixed tray tables have significant limitations: because they are permanently connected to the main body of the furniture, they cannot be folded up flexibly when not in use, resulting in wasted space, a problem that is particularly pronounced in small apartments. Furthermore, while some detachable tray tables with threaded connections offer some flexibility, they lack anti-misoperation designs. Users may accidentally rotate them in the opposite direction during daily use, causing the tray table to detach from the support rod, leading to structural loosening, tipping over, and other safety hazards. To address these issues, a tray table component and furniture parts incorporating it are proposed. Utility Model Content

[0034] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a tray table assembly and a furniture component having the same.
[0035] like Figures 1-12 As shown, the tray table assembly 100 according to an embodiment of the present utility model includes: a tray table 102, a support rod 104, a mounting bracket assembly 106 for fixing the support rod 104 to the lower side of the tray table 102, and a fastening assembly 108 for fixing the support rod 104 to its unfolded or retracted position, and for unlocking the support rod 104 so that it can move between the retracted and unfolded positions.
[0036] like Figure 3As shown, the mounting bracket assembly 106 includes a circular platform 110, on the end face of which are provided a plurality of first through holes 112. These first through holes 112 are arranged in an array along the circumferential direction of the circular platform 110. First threaded fasteners 114 are inserted into the first through holes 112. The first threaded fasteners 114 are used to fix the circular platform 110 to the underside of the tray table 102.
[0037] A first mounting plate 116 and a second mounting plate 118 are mounted on a circular platform 110. The first mounting plate 116 and the second mounting plate 118 are positioned opposite each other and spaced apart, and are parallel to each other. The first mounting plate 116 and the second mounting plate 118 are cantilevered on the circular platform 110 to effectively exhibit a predetermined amount of flexibility. The circular platform 110 also has a second through hole 120 located between the first mounting plate 116 and the second mounting plate 118. A threaded hole 122 is formed on the first mounting plate 116 along the arrangement direction of the first mounting plate 116 and the second mounting plate 118, and a third through hole 124 is formed on the second mounting plate 118 along the arrangement direction of the first mounting plate 116 and the second mounting plate 118. The central axis of the threaded hole 122 is collinear with the central axis of the third through hole 124. Figure 8-9 As shown, the support rod 104 has a cylindrical structure. Two cross-sections 128 are formed on the circumferential surface of the lower end of the support rod 104. The two cross-sections 128 are arranged opposite to each other. A fourth through hole 130 is formed at the lower end of the support rod 104 along the arrangement direction of the two cross-sections 128. The two ends of the fourth through hole 130 pass through the two cross-sections 128 respectively. When the lower end of the support rod 104 is inserted between the first mounting plate 116 and the second mounting plate 118, the central axis of the fourth through hole 130 is collinear with the central axis of the third through hole 124, so that the fastening assembly 108 can fix the support rod 104 and the circular platform 110 together in an adjustable manner. A cylindrical boss 132 is formed at the end of the support rod 104. The cylindrical boss 132 is used to insert into the second through hole 120 to play a role in positioning and maintaining stability.
[0038] like Figure 4-7As shown, the fastening assembly 108 includes a bolt 133, a handle 136, a coil spring 138, and a second threaded fastener 140 with external threads. One end of the bolt 133 has external threads, and the other end has internal threads. The handle 136 includes a lower hub 142 and a blade portion 144 extending radially outward from a specific circumferential point of the lower hub 142. One end of the lower hub 142 has a first recess 146 formed along its central axis, and the cross-section of the first recess 146 is hexagonal. The other end of the lower hub 142 has a second recess 148 formed along its central axis, and the cross-section of the second recess 148 is circular. A collar portion 150 is fitted onto the bolt 133. A protrusion 152 is formed on the end face of the collar portion 150 facing the other end of the bolt 133. The external cross-sectional shape of the protrusion 152 is hexagonal so that it can be inserted into the first recess 146. The helical spring 138 is inserted into the second recess 148, the other end of the bolt 133 passes through the helical spring 138, and the external thread of the second threaded fastener 140 is threadedly connected to the internal thread of the other end of the bolt 133.
[0039] Furthermore, such as Figure 4 As shown, a washer 154 is fitted onto one end of the bolt 133 so that it is close to and engages with the collar portion 150 of the bolt 133.
[0040] The second mounting plate 118 has a flat surface 156 on the side facing away from the first mounting plate 116. When the fastening assembly 108 passes through and fully engages with the third through hole 124, the fourth through hole 130 and the threaded hole 122, the washer 154 will fit against the flat surface 156.
[0041] During operation, when the blade portion 144 of the fastening assembly 108 is parallel to the tray table 102, the fastening assembly 108 is actually in a locked state, and the support rod 104 cannot move. When the blade portion 144 of the fastening assembly 108 is in any position other than parallel to the tray table 102, the fastening assembly 108 is actually in an unlocked state, allowing the support rod 104 to move between the retracted and extended positions. That is, when the blade portion 144 is rotated a quarter turn, i.e., 90 degrees, given that the threaded portion of the bolt 133 is located within the threaded hole 122 of the first mounting plate 116, when according to... Figure 7When the blade portion 144 of the fastening assembly 108 is rotated clockwise as shown, the first mounting plate 116 and the second mounting plate 118 will actually move closer to each other, effectively reducing the space or gap defined between the first mounting plate 116 and the second mounting plate 118. In this way, the support rod 104 will be tightly clamped between the first mounting plate 116 and the second mounting plate 118. The blade portion 144 drives the external thread portion of the bolt 133 to screw into or out of the threaded hole 122 of the first mounting plate 116, thereby adjusting the distance between the first mounting plate 116 and the second mounting plate 118. This allows the first mounting plate 116 and the second mounting plate 118 to clamp or move away from the two cut surfaces 128 on the support rod 104, thereby releasing or locking the angle of the support rod 104.
[0042] Specifically, the fourth through hole 130 is racetrack-shaped, and its length direction is parallel to the central axis of the support rod 104. When the support rod 104 moves from its central axis parallel to the tray table 102 to perpendicular to the tray table 102, the cylindrical boss 132 can move from the folded / stowed position (e.g., ...) through the space of the fourth through hole 130. Figure 2 and Figure 10 Move to the upright / expanded position (as shown) Figure 11 and Figure 12 As shown, by means of the elliptical or approximately elliptical fourth through hole 130 provided at the lower end of the support rod 104, the cylindrical boss 132 at the lower end of the support rod 104 can be inserted into the second through hole 120 to ensure the stability of the support rod 104 in supporting the tray table 102.
