Description

Technical Field

[0001] The utility model relates to the technical field of bedsteads, and more particularly to an adjustable bedside armrest. Background Art

[0002] With the continuous progress of society, people increasingly attach importance to the health and safety of the elderly. For the elderly or patients, it is relatively difficult to get up or lie down from the bed. Therefore, a bedside armrest mechanism installed on one side edge of the bedstead has emerged as the times require. The bedside armrest mainly provides a stable physical support for the elderly through the armrest main body higher than the bedstead to facilitate getting up.

[0003] In the prior art, for example, the patent with the publication number CN220898983U discloses a bedside armrest, which includes an armrest section and a support section. The armrest section is connected to the support section, and an adjustment sleeve is provided between the armrest section and the support section. The adjustment sleeve includes a support adjustment section and a telescopic adjustment section connected to it at an angle. The telescopic adjustment section is connected to an extension rod. The telescopic adjustment section and the extension rod are mainly used for insertion and positioning under the mattress to play an auxiliary fixing role. Although the armrest structure of this prior art can play a basic role in assisting getting up, there are still some deficiencies. For example, the width of the armrest section cannot be adjusted. If the width is too large, it will affect normal getting up, and conversely, if the width is too small, the auxiliary support effect is not good. And when the armrest is temporarily not needed in this existing structure, the entire armrest can only be removed and reinstalled later when needed, which is time-consuming and laborious, and the state switching is not convenient enough. Summary of the Utility Model

[0004] To overcome at least one defect in the above prior art, the utility model provides an adjustable bedside armrest, which has a simple structure and is easy to install, and can be applied to bedsteads of various different heights. In addition, the armrest frame part can be stored without removing other structures, realizing flexible switching between different use states.

[0005] The utility model provides an adjustable bedside armrest, which includes a vertically arranged support frame and a horizontally arranged fixed frame. One end of the fixed frame is used for insertion and positioning between the mattress and the bedstead, and the other end of the fixed frame is detachably connected to the support frame. The top of the support frame is also connected with a vertically arranged first armrest frame and a second armrest frame which are distributed up and down, and the second armrest frame can be folded down towards the direction away from the bedstead to a position parallel to the side of the bedstead for storage. At least one end in the length direction of the first armrest frame and the second armrest frame is telescopically connected with an extended armrest frame.

[0006] Compared with the prior art, the adjustable bedside armrest of the utility model has the following advantages:

[0007] 1. The armrest frame part includes a first armrest frame and a second armrest frame which are distributed vertically, and an extended armrest frame is telescopically connected to at least one end of the first armrest frame and the second armrest frame. Users can select the corresponding armrest frame for width expansion according to the thickness of the mattress. In practical applications, due to the difference in the thickness of the mattress, if the mattress is very thick and even exceeds the lower end face of the first armrest frame, then only the first armrest frame part can be widened. The entire armrest structure is convenient to use and flexible in switching between multiple states.

[0008] 2. The armrest frame part and the support frame part are rotatable. When the armrest function is not needed temporarily, the armrest frame part can be rotated outwards for storage without the need for overall removal. When the armrest function is needed again later, the armrest frame part can be folded back. It is very convenient. And the rotation structure in this structure is locked by a knob nut to ensure the stability of the armrest part in the use state.

[0009] 3. A height-adjustable foot is connected to the lower end of the support frame. The height of the fixed frame is adjusted by adjusting the height of the foot so that it can adapt to bed frames of different heights. In addition, the fixed frame and the support frame are also detachably connected, that is, the height of the fixed frame is adjusted by changing the height of the connection position. The combination of the two methods can make the height adjustment of the fixed frame more accurate and convenient.

[0010] Furthermore, the support frame includes two vertically connected pipes and a cross bar. The cross bar is connected between the two vertically connected pipes. The upper ends of the two vertically connected pipes are connected to the second armrest frame, and the fixed frame is detachably connected to the outer walls of the two vertically connected pipes.

[0011] Still further, the foot includes two vertically arranged support rods. The upper ends of the two support rods are slidably inserted into the lower ends of the two vertically connected pipes. A plurality of vertically arranged positioning through holes are connected to the side walls of the two vertically connected pipes. Elastic positioning columns that can be radially expanded are arranged on the outer walls of the upper ends of the two support rods, and the two elastic positioning columns are respectively positioned in the corresponding positioning through holes on the two vertically connected pipes.

[0012] As an improvement, the fixed frame includes a flat and overall U-shaped fixed frame. The two ends of the opening part of the fixed frame are respectively detachably connected to the two vertically connected pipes, and a plurality of circumferentially distributed and vertically penetrating connection holes are arranged on the fixed frame.

[0013] Further improved, both ends of the opening part of the fixed frame are connected with clamping units. Each clamping unit includes a first clamping block and a second clamping block which are oppositely arranged and semicircular in shape, and the convex sides of the two first clamping blocks are respectively connected to both ends of the opening part of the fixed frame. Connecting ear plates are arranged at both ends of the first clamping block and the second clamping block, and the connecting ear plates at both ends of the first clamping block and the connecting ear plates at both ends of the second clamping block are respectively connected by screws, so that the oppositely arranged first clamping blocks and second clamping blocks are clamped and limited outside the corresponding vertical connecting pipes.

[0014] Further improved, both the first handrail frame and the second handrail frame include two mutually parallel horizontal connecting pipes, and one end of the four horizontal connecting pipes is connected into one body through a vertical pipe. Two telescopic insertion pipes are arranged at one end of each lengthened handrail frame, and the four telescopic insertion pipes of the two lengthened handrails are respectively telescopically inserted and matched at the other ends of the four horizontal connecting pipes along their length directions.

[0015] Further improved, a plurality of first insertion holes arranged axially are provided on the side walls of at least one horizontal connecting pipe of the first handrail frame and at least one horizontal connecting pipe of the second handrail frame. Second insertion holes are provided on the telescopic insertion pipes of the two lengthened handrail frames. A C-shaped clamping ring is slidably clamped on the outer wall of the horizontal connecting pipe provided with the first insertion hole, and a positioning insertion pin is connected to the inner wall of the C-shaped clamping ring. The positioning insertion pin is sequentially inserted into the first insertion hole and the second insertion hole to realize the axial limit of the lengthened handrail frame and the first handrail frame or the second handrail frame.

[0016] Further improved, the two telescopic insertion pipes of each lengthened handrail frame are bent from a complete pipe, and the bent section of the pipe is an arc-shaped structure.

[0017] Further improved, decorative sleeves are sleeved at the ends of the horizontal connecting pipes away from the vertical rods.

[0023] First of all, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.

[0024] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "fixed" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0025] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0026] See Figure 1 、 Figure 2 As shown, the embodiments of the present application disclose an adjustable bedside armrest, including a vertically arranged support frame and a horizontally arranged fixed frame 1. That is, the support frame and the fixed frame 1 are vertically arranged as a whole. One end of the fixed frame 1 is used for inserting and positioning between the mattress and the bed frame, and the other end of the fixed frame 1 is detachably connected to the support frame. That is, in this armrest structure, in addition to being positioned between the mattress and the bed body through the fixed frame 1, it is also vertically supported by the support frame, fully ensuring the stability of the entire bedside armrest structure, not easily tipping over, and having high safety.

[0027] In addition, the top of the support frame is also connected with a first armrest frame 2 and a second armrest frame 3 which are vertically arranged and distributed up and down. The second armrest frame 3 can be folded downwards away from the bed frame and stored in a position parallel to the side of the bed frame. In this structure, the first armrest frame 2 and the second armrest frame 3 are fixed together. Therefore, when the second armrest frame 3 is folded and stored, the first armrest frame 2 is also stored synchronously. So when the armrest function is not temporarily needed, the armrest frame part can be turned outwards and stored, without the need to remove it as a whole. When the armrest function is needed again later, the armrest frame part can be folded back, which is very convenient. And the flipping structure in this structure is locked by a knob nut to ensure the stability of the armrest part in the use state.

[0028] On the other hand, in this embodiment, at least one end in the length direction of the first armrest frame 2 and the second armrest frame 3 is telescopically connected with an extended armrest frame 4. That is, by telescopically adjusting the extended armrest frame 4, the width of the first armrest frame or the second armrest frame 3 can be extended in the width direction, and the user can expand the width of the armrest frame part according to actual needs. And in actual application, due to the difference in the thickness of the mattress, if the thickness of the mattress is very large and even exceeds the position of the lower end face of the first armrest frame 2, then only the first armrest frame 2 part can be widened. The whole armrest structure is convenient to use and flexible in switching between multiple states.

[0029] On the other hand, in the above structure, a height-adjustable foot is connected to the lower end of the support frame, and the height of the fixing frame 1 is adjusted by adjusting the height of the foot so that it can adapt to bed frames of different heights. In this embodiment, in addition to the method of adjusting the foot, the height of the fixing frame 1 can also be adjusted by directly adjusting the fixing position of the fixing frame 1 and the vertical connecting pipe 5. The combination of the two methods can make the height adjustment of the fixing frame 1 more accurate and convenient.

[0030] In this embodiment, referring to the appendix Figure 1 , the support frame includes two vertical connecting pipes 5 and a cross bar 6. The two ends of the cross bar 6 are connected between the two vertical connecting pipes 5. Here, welding fixation is selected. Of course, in some other embodiments, the two ends of the cross bar 6 and the two vertical connecting pipes 5 can also be screwed and fixed through special connecting parts. The upper ends of the two vertical connecting pipes 5 are connected to the second armrest frame 3, and the fixing frame 1 is detachably connected to the outer walls of the two vertical connecting pipes 5.

[0031] The foot includes two vertically arranged support rods 20. The upper ends of the two support rods 20 are slidably inserted into the lower ends of the two vertically connecting pipes 5. A plurality of vertically arranged positioning through holes 7 are connected to the side walls of the two vertically connecting pipes 5. Elastic positioning columns 8 that can be radially expanded and contracted are provided on the outer walls of the upper ends of the two support rods 20, and the two elastic positioning columns 8 are respectively positioned in the corresponding positioning through holes 7 on the two vertically connecting pipes 5, so as to realize the connection and positioning of the support rod 20 and the vertically connecting pipe 5. By replacing the positioning through holes 7 with different heights, the height of the vertically connecting pipe 5 can be adjusted, and then the height of the fixing frame 1 can be adjusted.

[0032] In this embodiment, preferably, the fixing frame 1 includes a flat and overall U-shaped fixing frame. The flat structure will not affect the sleep comfort when it is inserted between the mattress and the bed frame. The two ends of the opening of the fixing frame are respectively detachably connected to the two vertically connecting pipes 5, and a plurality of circumferentially distributed and vertically penetrating connecting holes 9 are provided on the fixing frame. The connecting holes 9 here are used for inserting self-tapping screws. Users can choose according to the actual situation. If the pressing stability of the mattress alone is not enough, then self-tapping screws can be inserted into the connecting holes 9 to connect and fix the fixing frame to the bed board.

[0033] In the above structure, the two ends of the opening of the fixing frame are respectively detachably connected to the two vertically connecting pipes 5. Specifically, it means that clamping units are connected to both ends of the opening of the fixing frame. Each clamping unit includes a first clamping block 10 and a second clamping block 11 that are oppositely arranged and semicircular. The convex sides of the two first clamping blocks 10 are respectively connected to both ends of the opening of the fixing frame. Connecting ear plates 12 are provided at both ends of the first clamping block 10 and the second clamping block 11, and the connecting ear plates 12 at both ends of the first clamping block 10 and the connecting ear plates 12 at both ends of the second clamping block 11 are respectively connected by screws 13, so that the oppositely arranged first clamping block 10 and the second clamping block 11 are clamped and limited outside the corresponding vertically connecting pipe 5, realizing the connection and fixing of the fixing frame 1 and the support frame.

[0034] In this embodiment, the first armrest frame 2 and the second armrest frame 3 both include two mutually parallel transverse connecting pipes 14, and one end of the four transverse connecting pipes 14 is connected into one body through a vertical pipe 15. One end of each extended armrest frame 4 is provided with two telescopic insertion pipes 16, and the four telescopic insertion pipes 16 of the two extended armrests are respectively telescopically inserted and fitted at the other end of the four transverse connecting pipes 14 along their lengths. More specifically, a plurality of first insertion holes 17 arranged axially are provided on the side walls of at least one transverse connecting pipe 14 of the first armrest frame 2 and at least one transverse connecting pipe 14 of the second armrest frame 3. Second insertion holes are provided on the telescopic insertion pipes 16 of the two extended armrest frames 4. A C-shaped clamping ring 18 is slidably clamped on the outer wall of the transverse connecting pipe 14 provided with the first insertion hole 17. A positioning pin is connected to the inner wall of the C-shaped clamping ring 18, and the positioning pin is sequentially inserted into the first insertion hole 17 and the second insertion hole to realize the axial limit of the extended armrest frame 4 and the first armrest frame 2 or the second armrest frame 3. In this embodiment, the first insertion holes 17 are provided on the upper transverse connecting pipe 14 in the first armrest frame 2 and the lower transverse connecting pipe 14 in the second armrest frame 3. Of course, in some other embodiments, the first insertion holes 17 can also be provided on all four transverse connecting pipes 14.

[0035] In addition, the two telescopic insertion pipes 16 of each extended armrest frame 4 are both bent from a complete pipe, and the bent section of the pipe is an arc-shaped structure. The overall bending structure is convenient to process, and the bent end is transitioned through the arc-shaped structure to improve the appearance beauty.

[0036] Similarly, referring to the appendix Figure 1 , decorative sleeves 19 are sleeved on the ends of the four transverse connecting pipes 14 away from the vertical rods, which not only improves the appearance beauty, but also can prevent the ends of the transverse connecting pipes 14 from scratching users and improve the safety performance.

[0037] In addition, in this embodiment, rubber pads 21 are equipped at the bottoms of the two support rods 20 to prevent the support rods 20 made of metal from directly contacting the ground.
