[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1 The present invention provides a reversible bedside armrest comprising a fixing frame 1, a fixing rod 2, a fixing base 3, a rotating base 4, and an armrest frame 5. The fixing frame 1 forms a 90-degree angle with the fixing rod 2, and one end of the fixing frame 1 is fixedly connected to the fixing rod 2. In actual use, the fixing frame 1 is placed under the mattress to secure the entire bedside armrest. The two fixing rods 2 are fixedly connected by a connecting rod.
[0022] See also Figure 2The top of the fixed rod 2 is fixedly connected to the fixed seat 3. The rotating seat 4 includes a rotating disk 41 and a rotating rod 42. The rotating rod 42 is fixedly connected to the rotating disk 41. The fixed seat 3 and the rotating disk 41 rotate coaxially. The rotating rod 42 is movably hinged between the rotating disk 41 and the fixed seat 3. The rotating rod 42 rotates along the outer wall of the fixed seat 3. The hinge point between the rotating rod 42 and the fixed seat 3 is no higher than the height of the mattress. A return spring 43 and a latch 44 are provided in the rotating rod 42. The bottom of the return spring 43 is connected to the latch 44, and the top of the return spring 43 is fixedly connected to the rotating rod 42. The elastic direction of the return spring 43 is toward the latch 44. The fixed seat 3 is provided with a fixing hole 31. The latch 44 slides within the rotating rod 42 and moves in and out of the fixing hole 31. A support rod 6 is positioned between the two rotating rods 42. A connecting shaft is fixedly mounted at each end of the support rod 6. A movable slot is defined in the sidewall of the rotating rod 42, the length of the slot aligning with the axis of the rotating rod 42. The connecting shaft passes through the slot and is fixedly connected to one side of a latch 44. The connecting shaft moves within the slot, allowing limited movement. The support rod 6, via the connecting shaft, drives the latch 44 to slide within the rotating rod 42, thereby controlling the latch 44's movement within the fixing hole 31. Lifting and lowering the support rod 6 changes the connection between the latch 44 and the fixing hole 31 at each end of the support rod 6. When the latch 44 leaves the fixing hole 31, the rotating disk 41 rotates along the outer edge of the fixing base 3, causing the rotating rod 42 to flip. When the latch 44 enters the fixing hole 31, the position between the rotating disk 41 and the fixing base 3 is fixed. The movable slot limits the movement of the connecting shaft, thereby limiting the travel distance of the latch 44. When the latch 44 leaves the fixing hole 31 and the rotating disk 41 rotates along the outer edge of the fixing seat 3, the latch 44 moves against the outer wall of the fixing seat 3 due to the setting of the return spring 43. When the latch 44 and the fixing hole 31 are aligned, the latch 44 automatically falls into the fixing hole 31 due to the elasticity of the return spring 43. The rotating rod 42 is fixedly connected to the armrest frame 5. Therefore, when the rotating rod 42 is turned, the armrest frame 5 turns with it, thereby enabling the height of the armrest frame 5 to be quickly adjusted to be lower than the mattress height to avoid blocking the way in and out of the bed.
[0023] See also Figure 1 The armrest frame 5 is provided with an armrest adjustment rod 51 connected to the rotating rod 42. The rotating rod 42 is mounted on the outer wall of the armrest adjustment rod 51. The armrest adjustment rod 51 has several armrest adjustment holes distributed along the axis of the armrest adjustment rod 51. The rotating rod 42 has an armrest fixing hole, which is connected to any of the armrest adjustment holes via a fixed armrest pin. The armrest fixing hole is connected to different armrest adjustment holes to adjust the height of the armrest frame 5 to meet the needs of people of different heights. The armrest frame 5 is equipped with horizontal and vertical armrests to meet the needs of different situations. The armrest frame 5 also has a storage bag for convenient access to items.
[0024] See also Figure 1In order to make the overall supporting force of the bedside armrest better, in this embodiment, preferably, a supporting foot 7 is provided under the fixing rod 2, and the lower end of the fixing rod 2 is sleeved on the upper end of the supporting foot 7. The lower end of the fixing rod 2 is provided with a plurality of support adjustment holes arranged along the axial direction of the fixing rod 2, and the supporting foot 7 is provided with a support fixing hole. The support fixing hole is connected with any support adjustment hole through a fixed support pin. By adjusting the connection between the support fixing hole and different support adjustment holes, the height of the fixing rod 2 can be adjusted. Because in actual circumstances, the heights of different styles of bed frames are different, in order for the supporting foot 7 to better contact the ground and thus support the fixing rod 2, it is necessary to adjust the connection between the appropriate support adjustment hole and the support fixing hole.
[0025] In order to limit the moving direction of the rotating disk 41, in this embodiment, preferably, the fixed seat 3 and the rotating disk 41 are connected to each other on the side facing each other, and a limit shaft 46 is fixed in the rotating disk 41, and the limit shaft 46 is axially extended from the rotating shaft toward the fixed seat 3, and a limit block 32 is fixed in the fixed seat 3. When the rotating disk 41 rotates, the limit shaft 46 will abut against the limit block 32 to limit the rotation of the rotating disk 41. The setting of the limit shaft 46 and the limit block 32 can prevent the rotating disk 41 from excessive rotation and limit the rotation direction of the rotating seat 4. When the limit shaft 46 abuts against the limit block 32, the pin 44 reaches above the fixing hole 31, which can prompt the operator that the pin 44 and the fixing hole 31 can be connected. If the pin 44 fails to enter the fixing hole 31 as normally at this time, it proves that the structure in the rotating rod 42 may be offset or damaged, and needs to be repaired in time.
[0026] The specific working process of this embodiment is as follows: when the armrest frame 5 needs to be flipped, the support rod 6 is lifted upward, the latch 44 is disengaged from the fixing hole 31, and the armrest frame 5 is flipped to the bottom in the direction away from the mattress. Figure 3 When the armrest 5 is needed, the armrest 5 is flipped toward the mattress, and the latch 44 automatically falls into the fixing hole 31 to complete the fixation.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
