Description

Technical Field

[0001] This utility model belongs to the field of bedside handrail technology, specifically relating to a retractable bedside handrail. Background Technology

[0002] Bedside handrails are assistive devices installed beside the bed, primarily used to provide support and safety for people with limited mobility, such as the elderly, pregnant women, and people with disabilities, when getting up, getting in and out of bed, or turning over. The current bedside handrails are not height-adjustable, which limits their use. For example, when changing the mattress and the bed height changes, or when the bed needs to be moved to a mattress of a different height, the non-adjustable bedside handrails may no longer be suitable and cannot continue to provide appropriate support and safety for the user. Utility Model Content

[0003] This addresses the technical problem that the height of existing retractable bedside armrests cannot be adjusted.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a retractable bedside armrest, comprising a left retractable component, a right retractable component, and a control crossbar, wherein the left retractable component and the right retractable component are connected by the control crossbar;

[0005] Both the left telescopic component and the right telescopic component have a hollow first column and a hollow second column, so that the first column is inserted into the second column;

[0006] The bottom of the first column is equipped with a locking component, and the control bar is equipped with a control component. The control component is connected to the locking component. Pressing the control component can control the locking component to move back and forth in the first column to lock or unlock.

[0007] Furthermore, the locking assembly includes a locking body, a locking push rod, and a locking member. The locking member has a pushing groove, which is located in the locking body. The bottom of the locking push rod is located in the pushing groove. The sidewall of the pushing groove and the bottom of the locking push rod are both set as inclined structures. The inclined structure of the locking push rod moves along the sidewall of the inclined structure of the locking member, which can push the lock back into the locking body.

[0008] Furthermore, a return spring is provided between one side of the locking member and the side wall of the locking member body, and the locking post on the other side of the locking member extends to the outside of the first post.

[0009] Furthermore, the control assembly includes a housing, a control button, a push component, and a connecting component. The top side of the control button is located in the housing. Both ends of the control button are connected to push components. Both push components are hinged to the housing via pin shafts. The other end of both push components is connected to a connecting component. The connecting components on both sides are connected to the locking push rods of the locking assemblies on both sides.

[0010] Furthermore, a locking hole is provided in the side wall at the top of the second column, and the locking pin of the locking member is located in the locking hole of the second column, so that the first column and the second column are locked together.

[0011] Furthermore, the left telescopic component and the right telescopic component are provided with a third column, and the second column is inserted into the third column.

[0012] Furthermore, a first crossbar, a second crossbar, and a cross tube are provided between the left telescopic assembly and the right telescopic assembly.

[0013] The present invention has the following advantages: pressing the control component can control the locking component to move back and forth in the first column, thereby controlling the locking or unlocking between the first column and the second column to achieve telescopic height adjustment. The entire product can be used in different application scenarios. Attached Figure Description

Detailed Implementation

[0022] like Figures 1 to 7 As shown, a retractable bedside armrest includes a left telescopic component 10, a right telescopic component 20, and a control crossbar 30. The tops of the left telescopic component 10 and the right telescopic component 20 are connected by the control crossbar 30.

[0023] The left telescopic assembly 10 and the right telescopic assembly 20 both have a hollow first column 11 and a hollow second column 12. The outer diameter of the first column 11 is smaller than the inner diameter of the second column 12, so that the first column 11 can be inserted into the second column 12.

[0024] The bottom of the first column 11 is provided with a locking component 40, and the control bar 30 is provided with a control component 50. The control component 50 is connected to the locking component 40. Pressing the control component 50 can control the locking component 40 to move back and forth in the first column 11 to lock or unlock.

[0025] The locking assembly 40 includes a locking body 41, a locking push rod 42, and a locking member 43. The locking member 43 has a pushing groove 44, which is located in the locking body 41. The bottom of the locking push rod 42 is located in the pushing groove 44. The side wall of the pushing groove 44 and the bottom of the locking push rod 42 are both set as inclined structures. The inclined structure of the locking push rod 42 moves along the side wall of the inclined structure of the locking member 43, which can push the locking member 43 back into the locking body 41.

[0026] A return spring 45 is provided between one side of the locking member 43 and the side wall of the locking member body 41, and the locking post 46 on the other side of the locking member 43 extends to the outside of the first post 11.

[0027] The control assembly 50 includes a housing 31, a control button 32, a pusher 33, and a connecting member 34. The top side of the control button 32 is located in the housing 31. Both ends of the control button 32 are connected to the pusher 33. Both pushers 33 are hinged to the housing 31 via pin shafts. The other end of both pushers 33 is connected to the connecting member 34. The connecting members 34 on both sides are connected to the locking push rods 42 of the locking assemblies 40 on both sides.

[0028] The second column 12 has a locking hole 13 in the side wall at the top. The locking pin 46 of the locking member 43 is located in the locking hole 13 of the second column 12, so that the first column 11 and the second column 12 are locked together.

[0029] In use, pressing the control button 32 on the control lever 30 moves it upwards. The pushing components 33 on both sides push the connecting component 34 downwards around the pin shaft. The connecting component 34 pushes the locking push rod 42 downwards. The locking push rod 42 and the locking member 43 cooperate through the inclined structure, causing the locking member 43 to retract into the locking member body 41. The return spring 45 between the locking member 43 and the locking member body 41 is compressed and contracted. At this time, the locking pin 46 of the locking member 43 disengages. In the locking hole 13 of the second column 12, the first column 11 can move downwards and retract into the second column 12 for storage. When the first column 11 needs to be unfolded from the second column 12, the control bar 30 is pulled upwards. When the locking post 46 of the locking member 43 moves to the position of the corresponding locking hole 13, the retracted return spring 45 pushes the locking member 43 outwards by its own elastic force, so that the locking post 46 is set in the locking hole 13, and the first column 11 and the second column 12 are locked together to complete the unfolding.

[0030] The left telescopic assembly 10 and the right telescopic assembly 20 are also provided with a third column 14. The inner diameter of the third column 14 is larger than the outer diameter of the second column 12. The second column 12 is inserted into the third column 14. The bottom of the second column 12 is provided with a locking assembly 40 of the same structure. The top of the third column 14 is provided with a locking hole 13 of the same structure. Similarly, the locking assembly 40 is driven by the connecting component 34 to control the switch lock, so that the second column 12 can be retracted into the third column 14 or unfolded from the third column 14.

[0031] A first crossbar 21, a second crossbar 22, and a horizontal tube 23 are also provided between the left telescopic component 10 and the right telescopic component 20. The first crossbar 21, the second crossbar 22, and the horizontal tube 23 make the structure between the left telescopic component 10 and the right telescopic component 20 more stable.
