Description

Technical Field

[0001] The utility model relates to the technical field of bed armrests, in particular to a bed armrest and an electric bed. Background Art

[0002] Due to economic development and people's increasing attention to quality of life, electric beds are already available in the prior art that use motors to lift the back and / or leg beds to achieve changes in the bed frame posture, thereby improving the user's sleeping or lying comfort.

[0003] In order to prevent users from falling or to assist users in getting up, some electric beds will add bed armrests on both sides of the bed board. For example, the Chinese invention patent application with application publication number "CN113876137A" discloses an adjustable electric bed with guardrails fixed on both sides of the top surface of the backboard by screws. However, this technical solution also has some shortcomings. For example, since the armrests are fixed to the backboard, when the backboard is raised, the bed armrests will rise with the bedboard, which is not conducive to users getting out of bed when it is raised. In addition, some bed armrests are installed on the bed frames on both sides of the bed frame. However, since the distance that the bed board of each electric bed extends out of the bed frame is different, the bed armrests cannot be adapted to all electric beds. Moreover, due to the different thicknesses of the mattresses on the electric beds, the electric beds also need to be customized with bed armrests of matching height.

[0004] Therefore, a bed armrest and an electric bed that can match different types of electric beds and have strong adaptability need to be designed. Utility Model Content

[0040] 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.

[0041] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in the present invention to indicate positions or positional relationships are based on the positions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific position, be constructed, or operate in a specific position. Therefore, they should not be construed as limiting the present invention. In addition, terms such as first and second are used only to distinguish multiple components or structures having the same or similar structures and do not represent any special limitation on the arrangement order or connection relationship.

[0042] Please refer to Figures 1 to 6The present invention provides a bed armrest 100 for being assembled on a bed frame 210 to prevent a user from falling or to assist a user in getting up. The bed armrest 100 comprises a fixing frame 1, a telescopic fixing plate 2 and an armrest assembly 3.

[0043] One end of the fixing frame 1 is sleeved and fixed on the bed frame 210 , so that the bed armrest 100 can be stably fixed and assembled with the bed frame 210 .

[0044] One end of the telescopic fixing plate 2 can be telescopically configured at the end of the fixing frame 1 away from the bed frame 210, and is locked with the fixing frame 1 through the first locking member; in this way, the distance between the telescopic fixing plate 2 and the bed frame 210 can be adjusted.

[0045] The armrest assembly 3 can be adjusted up and down at the end of the telescopic fixing plate 2 away from the fixing frame 1 and locked with the telescopic fixing plate 2 by a first fastener; in this way, the relative height between the armrest assembly 3 and the bed frame 210 can be adjusted.

[0046] Since the armrest assembly 3 of the bed armrest 100 can adjust the relative horizontal distance between it and the bed frame 210, as well as the relative height between it and the bed frame 200, it has the advantage of being able to match different types of electric beds 1000 and having strong adaptability.

[0047] Alternatively, see Figure 3 、 Figure 5 and Figure 6 In this embodiment, the fixing frame 1 includes two sleeves 11 and a sleeve assembly plate 12. The two sleeves 11 are arranged in parallel. The sleeve assembly plate 12 connects the ends of the two sleeves 11 away from the telescopic fixing plate 2 and cooperates with the ends of the two sleeves 11 away from the telescopic fixing plate 2 to form an open card slot a. Optionally, the sleeve assembly plate 12 can be fixed to the ends of the two sleeves 11 away from the telescopic fixing plate 2 by welding or screws. The fixing frame 1 is sleeved onto at least a portion of the outer periphery of the bed frame 210 through the open card slot a, and the bed frame 210 is tightened into the open card slot a by a second locking member. Specifically, the open card slot a of the fixing frame 1 can sleeve and cover 3 / 4 of the outer periphery of the bed frame 210. Of course, in other embodiments, the open card slot a of the fixing frame 1 can also sleeve and cover the entire outer periphery of the bed frame 210, which is not limited to this specific embodiment.

[0048] Optionally, in order to realize the telescopic adjustment function between the telescopic fixing plate 2 and the fixing frame 1, optionally, please refer to Figure 5In this embodiment, the telescopic fixing plate 2 is L-shaped and includes a crossbar and a vertical plate 22 connected to the crossbar. The crossbar of the telescopic fixing plate 2 is composed of two open slotted tubes 21 that match the inner diameter of the sleeve 11. The outer circumferences of the two sleeves 11 are provided with locking holes o1. The first locking member is a flat-head thumb screw 4 that secures the open slotted tubes 21 against the inner wall of the sleeve 11 through the locking holes o1. Specifically, the locking holes o1 are threaded locking holes o1. During assembly, the open slotted tubes 21 of the telescopic fixing plate 2 can be adjusted to the appropriate position, and then the first locking member can be inserted through the locking holes o1 of the sleeve 11 to secure the open slotted tubes 21 against the inner wall of the sleeve 11, thereby locking the telescopic fixing plate 2 to the fixing frame 1 through friction. Of course, in other embodiments, the crossbar of the telescopic fixing plate 2 can also be a solid rod or tube that matches the inner diameter of the two sleeves 11, as long as it can achieve telescopic fit with the fixing frame 1. This is not a specific limitation here.

[0049] In order to realize the sleeve fixing between the fixing frame 1 and the bed frame 210, optionally, please refer to Figures 3 to 5 In this embodiment, the sleeve assembly plate 12 has two vertically arranged first ear plates 121. Specifically, the first ear plates 121 are spaced apart and, when assembled, are located on both sides of the bed frame 210 along with the end of the sleeve 11 away from the telescopic fixing plate 2. The second locking member cooperates with the threaded hole o2 on the first ear plate 121 to tighten the bed frame 210 into the open card slot a. Optionally, the second locking member is a torx head hand screw 5. By tightening the second locking member, the free end of its rod presses the bed frame 210 against the end of the sleeve 11 away from the telescopic fixing plate 2, and the bed frame 210 is sleeved and fixed to the fixing frame 1 through friction.

[0050] In order to increase the friction between the end of the sleeve 11 away from the telescopic fixing plate 2 and the bed frame 210, and to make the pressure between the second locking member and the bed frame 210 more uniform. Figure 5 In this embodiment, an anti-slip pad 7 is provided at the end of the sleeve 11 away from the telescopic fixing plate 2. Specifically, the anti-slip pad 7 can be adhesively fixed to the end of the sleeve 11 away from the telescopic fixing plate 2. A pressing piece 51 is also provided at the end of the rod of the second locking member away from the head.

[0051] In order to prevent the second locking member from failing and causing the bed armrest 100 to separate from the bed frame 210 and cause the user to fall. Figure 4 and Figure 5In this embodiment, the sleeve assembly plate 12 further includes two second lugs 122. These are spaced apart and positioned on either side of the bed frame 210 when the open slot a of the sleeve assembly plate 12 is engaged with the bed frame 210. The bed armrest 100 also includes fastening bolts 8 that penetrate the two second lugs 122 and secure the bed frame 210 within the open slot a. This prevents the bed armrest 100 from detaching from the bed frame 210 even if the second locking member fails.

[0052] In order to achieve the up and down adjustment positioning between the armrest assembly 3 and the telescopic fixing plate 2, optionally, please refer to Figure 5 In this embodiment, the vertical plate 22 of the telescopic fixing plate 2 is vertically spaced apart with a plurality of through-holes o3.

The first fastener is a threaded fastener 6 that screws the armrest mounting base 31 to the vertical plate 22 through one of the through-holes o3 and the docking screw hole o4. Preferably, the vertical plate 22 of the telescopic fixing plate 2 is vertically spaced apart with two rows of through-holes o3. The lower end of the armrest mounting base 31 has two horizontally arranged docking rods 311, each with a docking screw hole o4 at its center. The threaded fastener 6 secures the armrest assembly 3 to the corresponding position on the telescopic fixing plate 2 by selecting through-holes o3 and docking screw holes o4 that match the thickness of the mattress (not shown).

[0053] In order to realize the quick assembly or disassembly of the handrail rod and the handrail fixing seat 31, optionally, please refer to Figure 5 In this embodiment, a sleeve 312 is vertically disposed at the upper end of the armrest fixing base 31; the outer periphery of the sleeve 312 has a lock hole o5; the armrest rod is a curved tube armrest rod 32, and the lower end of the armrest rod has an elastic buckle 322. The lower end of the armrest rod is inserted into the sleeve 312 and is locked with the lock hole o5 via the elastic buckle 322. Specifically, two sleeves 312 are vertically disposed at the upper end of the armrest fixing base 31; the lower end of the armrest rod has two insertion rods 321 that match the inner diameter of the sleeve 312, and the outer periphery of the insertion rods 321 has an elastic buckle 322. During assembly, the two insertion rods 321 of the armrest rod are inserted into the two sleeves 312 and locked with the elastic buckle 322.

[0054] In order to prevent the mattress from contacting the inner side of the vertical plate 22 of the telescopic fixed plate 2 and wearing the outer surface of the mattress when the bed plate 300 of the electric bed 1000 is lifted, please refer to Figure 5 In this embodiment, the bed armrest 100 further includes a soft furniture cover 9 disposed on the side of the riser 22 of the telescopic fixing plate 2 near the bed frame 210.
