Description

Technical Field

[0001] This utility model belongs to the field of bed technology and relates to a lifting bed. Background Technology

[0002] Existing pneumatic lifting beds include a bed frame and a slatted frame. The slatted frame is connected to the bed frame via a first link and a second link, so that the tail end of the slatted frame can be raised and lowered relative to the bed frame. A gas spring is installed between the first link and the slatted frame. The second link is connected to the head end of the slatted frame. The two ends of the second link are hinged to the bed frame and the slatted frame, respectively, making the installation process inconvenient. Summary of the Invention

[0003] This utility model addresses the problems existing in the prior art by proposing a lifting bed, aiming to overcome the inconvenience of installation of existing lifting beds.

[0004] This utility model is implemented as follows:

[0005] A lifting bed includes a bed frame and a slatted frame, with a connecting rod between the bed frame and the slatted frame. The bed frame has a movable support fixed to its head end, and the slatted frame has its head end movable back and forth on the movable support. A gas spring is provided between the bed frame and the connecting rod.

[0006] The extension and retraction of the gas spring drives the linkage, thereby enabling the entire frame to lift and lower. The forward and backward movement of the head end of the frame on the movable support provides the necessary space and guidance for the lifting and lowering of the frame.

[0007] By eliminating the hinged connections between the second link and the bed frame and slatted frame at both ends in the traditional design, and instead installing a movable support at the head end of the bed frame, the installation process is greatly simplified, reducing installation difficulty and time costs. The movable support provides stable guidance for the forward and backward movement of the slatted frame head end, ensuring that the slatted frame moves along a predetermined trajectory during lifting and lowering, avoiding problems such as deviation and swaying, and improving the stability and reliability of the bed.

[0008] Preferably, the head end of the slatted frame is equipped with rollers, and the slatted frame is placed on the movable support via the rollers. When the gas spring extends or retracts, driving the connecting rod to move, thereby causing the slatted frame to lift or lower, the rolling of the rollers at the head end of the slatted frame reduces friction, making the movement of the slatted frame during lifting and lowering smoother.

[0009] Preferably, the slatted frame includes a headboard frame and side frames, with mounting bases fixed at the corners where the headboard frame and side frames connect, and the rollers mounted on the mounting bases. The headboard frame and side frames of the slatted frame are typically made of wood, while the mounting bases can be made of stainless steel, which helps improve the stability of the roller installation.

[0010] Preferably, the mounting base includes an inner mounting ear and an outer mounting ear, both of which are provided with a rotating shaft. The rotating shaft protrudes outward from the outer mounting ear to form a mounting portion, and the roller is mounted on the mounting portion. This double-ear structure increases installation stability and force distribution. The protruding rotating shaft forming the mounting portion provides a more suitable installation position and space for the roller, making the roller installation more precise and stable. It also facilitates smooth rolling of the roller around the rotating shaft, thereby enabling stable and flexible movement of the slat frame on the moving support.

[0011] Preferably, the headboard frame and the side frame are fixedly connected by corner connectors, and the mounting base is simultaneously fixedly connected to the headboard frame, the side frame, and the corner connectors. The corner connectors themselves enhance the strength of the connection between the headboard frame and the side frame. The simultaneous fixing of the mounting base to these three components forms a tighter and more stable overall structure, distributing the force borne by the rollers from the lifting of the slatted frame more evenly across the entire frame and avoiding localized stress concentration.

[0012] Preferably, the first end of the connecting rod is hinged to the frame at a first hinge position, the second end of the connecting rod is hinged to the bed frame at a second hinge position, and the gas spring is hinged to the connecting rod at a third hinge position, which is offset towards the first hinge position. Offsetting the third hinge position of the gas spring and connecting rod towards the first hinge position is based on the principle of levers, which can change the force transmission path and effect, allowing the gas spring's extension force to generate a more reasonable torque on the connecting rod, thereby more efficiently driving the frame to perform lifting and lowering operations.

[0013] Preferably, the gas spring is hinged to the bed frame at the fourth hinge position, which is located at the lower end of the bed frame. The lower position of the fourth hinge position increases the angle between the gas spring and the connecting rod, allowing the gas spring to exert a larger component force on the connecting rod, thus making more full use of the gas spring's force. This helps reduce the required spring force and consequently lowers costs.

[0014] Preferably, after the slat frame is lowered, the angle between the gas spring and the connecting rod is greater than 30°.

[0015] Preferably, after the slat frame is raised, the angle between the gas spring and the connecting rod is greater than 80°.

[0016] The present invention has the following advantages: by eliminating the hinge structure between the two ends of the second connecting rod and the bed frame and the slat frame respectively in the traditional solution, and instead setting a movable support at the head end of the bed frame, the head end of the slat frame is placed directly on the movable support, which greatly simplifies the installation process and reduces the installation difficulty and time cost.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This embodiment provides a lifting bed, such as Figure 1-4 As shown, the bed includes a bed frame 100 and a slatted frame 200. A connecting rod 300 is provided between the bed frame 100 and the slatted frame 200. A movable support 110 is fixed to the head end of the bed frame 100. The head end of the slatted frame 200 is movably placed on the movable support 110. A gas spring 400 is provided between the bed frame 100 and the connecting rod 300.

[0024] The extension and retraction of the gas spring 400 drives the connecting rod 300 to move, thereby enabling the entire frame 200 to achieve the lifting function. The forward and backward movement of the head end of the frame 200 on the movable support 110 provides the necessary space and guidance for the lifting of the frame 200.

[0025] By eliminating the hinged structure at both ends of the second connecting rod to the bed frame 100 and the slatted frame 200 respectively in the traditional design, and instead setting a movable support 110 at the head end of the bed frame 100, the head end of the slatted frame 200 rests directly on the movable support 110, greatly simplifying the installation process and reducing installation difficulty and time costs. The movable support 110 provides stable guidance for the forward and backward movement of the head end of the slatted frame 200, ensuring that the slatted frame 200 can move along a predetermined trajectory during lifting and lowering, avoiding problems such as deviation and swaying, and improving the stability and reliability of the bed.

[0026] like Figure 2-3 As shown, the head end of the slatted frame 200 is provided with rollers 210, and the slatted frame 200 is placed on the movable support 110 via the rollers 210. When the gas spring 400 extends and retracts, driving the connecting rod 300 to move, thereby causing the slatted frame 200 to perform lifting and lowering operations, the head end of the slatted frame 200 relies on the rolling of the rollers 210 to reduce friction, making the movement of the slatted frame 200 smoother during the lifting and lowering process. The movable support 110 has an L-shaped cross-section, in which the vertical plate is fixed to the bed frame 100 by screws, and the horizontal plate extends front and rear to support the rollers 210, with the rollers 210 rolling on the upper surface of the horizontal plate. In other optional embodiments, the head end of the slatted frame 200 can also slide in cooperation with the movable support 110. In other optional embodiments, ball bearings can also be provided on the upper surface of the horizontal plate, so that the head end of the slatted frame 200 may not be provided with rollers 210, forming a rolling cooperation with the movable support frame.

[0027] like Figure 1 , 2 As shown, the slatted frame 200 includes a headboard frame 220 and side frames 230. A mounting base 240 is fixed at the corner where the headboard frame 220 and the side frames 230 connect. The rollers 210 are mounted on the mounting base 240. The headboard frame 220 and side frames 230 of the slatted frame 200 are typically made of wood, while the mounting base 240 can be made of stainless steel, which helps improve the stability of the rollers 210. In other optional embodiments, the rollers 210 can also be directly mounted to the slatted frame 200 via a pivot 243.

[0028] The bed frame 100 has movable support members 100 at both ends of the headboard. The two sets of movable support members 100 are symmetrically arranged. Correspondingly, the rollers 210 and the mounting bases 240 are also arranged on the left and right sides, so that the bed frame 100 can provide stable support for the frame 200.

[0029] like Figure 2As shown, the mounting base 240 includes an inner mounting ear 241 and an outer mounting ear 242. A rotating shaft 243 is provided on both the inner and outer mounting ears 241 and 242. The rotating shaft 243 protrudes outward from the outer mounting ear 242 to form a mounting portion, and the roller 210 is mounted on this mounting portion. This double-ear structure increases installation stability and force distribution. The protruding rotating shaft 243 provides a more suitable mounting position and space for the roller 210, making its installation more precise and stable. It also facilitates smooth rolling of the roller 210 around the rotating shaft 243, thereby enabling the frame 200 to move stably and flexibly on the movable support 110.

[0030] like Figure 1 , 2 As shown, the headboard frame 220 and the side frame 230 are fixedly connected by corner connectors 250. The mounting base 240 is simultaneously fixedly connected to the headboard frame 220, the side frame 230, and the corner connectors 250. The corner connectors 250 themselves enhance the strength of the connection between the headboard frame 220 and the side frame 230. The mounting base 240, when fixed to all three, forms a tighter and more stable overall structure, distributing the force borne by the rollers 210 from the lifting and lowering of the frame 200 more evenly across the entire frame, avoiding localized stress concentration.

[0031] like Figure 2-4 As shown, the first end of the connecting rod 300 is hinged to the frame 200 at the first hinge position 310, and the second end of the connecting rod 300 is hinged to the bed frame 100 at the second hinge position 320. The gas spring 400 is hinged to the connecting rod 300 at the third hinge position 410, which is offset from the first hinge position 310. Offsetting the third hinge position 410 of the gas spring 400 and the connecting rod 300 towards the first hinge position 310 is based on the principle of levers, which can change the force transmission path and effect, allowing the extension force of the gas spring 400 to generate a more reasonable torque on the connecting rod 300, thereby driving the frame 200 to perform lifting and lowering operations more efficiently.

[0032] like Figure 3 , 4 As shown, the gas spring 400 is hinged to the bed frame 100 at the fourth hinge position 420, which is located at the lower end of the bed frame 100. The lower position of the fourth hinge position 420 increases the angle between the gas spring 400 and the connecting rod 300, allowing the gas spring 400 to exert a larger component force on the connecting rod 300. This more fully utilizes the force of the gas spring 400, reducing the required spring force and thus lowering costs.

[0033] like Figure 3As shown, after the frame 200 descends, the angle between the gas spring 400 and the connecting rod 300 is greater than 30°.

[0034] like Figure 4 As shown, after the frame 200 is raised, the angle between the gas spring 400 and the connecting rod 300 is greater than 80°. This allows the use of a relatively small-force gas spring 400 to meet the needs of working with heavier mattresses, for example, a 50 kg mattress can be placed on the frame 200 with a thrust of 1000 Newtons from the gas spring 400.

[0035] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
