Description

Technical Field

[0001] The invention relates to the field of household beds, and in particular to a lifting bed. Background Art

[0002] In order to make full use of the space under the bed to store objects and expand the use function of the bed, the bed frame or bed board is required to be able to achieve the function of lifting and lowering. The liftable bed frames currently produced on the market are mainly divided into two categories: electric liftable bed frames and bed frames that are lifted and lowered by elastic lifters. The electric liftable bed frame mainly lifts the bed frame or bed board by turning on the electric lifter. Its disadvantage is that the electric lifter requires power support, and during the lifting process, if there is a power outage, the bed frame or bed board will stay in a certain position in the space and cannot be restored. In addition, the cost of the electric liftable bed frame is relatively high. Therefore, more and more businesses use elastic lifters as the power source for lifting bed frames, but it still has the following disadvantages:

[0003] First of all, the fixing plates of most lifts are fixed to the lift bed body by fasteners such as screws or bolts. Due to the heavy weight of the bed board, the fixing plates are easily damaged after a period of use, which not only shortens the service life of the lift, but also easily causes safety accidents.

[0004] Secondly, since the rigidity of the piston rod in the lift is limited, the higher the bed frame rises in parallel, the greater the shaking of the bed frame and the greater the load on the lift, which will pose a great safety hazard. Summary of the invention

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a lifter for a lift bed which has smooth lifting, labor-saving, stable and reliable, simple structure and high bearing strength, and a lift bed having the lifter.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A lifting bed comprises a bed body, a bed frame covering the bed body, and a lifting device for the lifting bed used to drive the bed frame to open or close relative to the bed body, wherein the lifting device comprises a fixing plate and a connecting rod lifting mechanism, wherein:

[0008] There are two groups of lifters for the lifting bed, which are respectively arranged on both sides of the bed body; an anti-shake mechanism is also arranged between the two groups of lifters for the lifting bed;

[0009] At least one load-bearing mechanism is provided below the fixing plate, and the bottom end of the load-bearing mechanism is supported on the ground.

[0010] The present invention provides a lifting bed. By arranging lifting bed lifters on both sides of the lifting bed body, two sets of lifters can drive the bed frame to move at the same time, so that the lifting of the bed frame can be more stable, and the two sets of lifters can jointly bear the weight of the bed frame. By arranging an anti-shake mechanism between the two sets of lifting bed lifters, the stability between the two lifters is improved, so that the lifting bed frame will not shake during the parallel lifting process; by arranging at least one load-bearing mechanism under the fixed plate, and the bottom end of the load-bearing mechanism is supported on the ground, the ground support can be used to give the fixed plate sufficient load-bearing force, ensuring that the fixed plate is not easily damaged, thereby extending the service life of the lifting bed lifter.

[0011] Furthermore, the connecting rod lifting mechanism includes a parallel connecting rod, a first rocker connecting rod, a second rocker connecting rod and a supporting connecting rod which are rotatably connected to each other; the parallel connecting rod, the first rocker connecting rod, the second rocker connecting rod and the supporting connecting rod are connected end to end in sequence to form a closed four-bar connecting rod mechanism; the second rocker connecting rod and the supporting connecting rod are rotatably connected to the fixed plate at the same time.

[0012] Thus, by driving the connecting rod lifting mechanism to move, a triangular support structure is formed between the parallel connecting rod, the first rocker connecting rod, the second rocker connecting rod and the lifting gas spring in the connecting rod mechanism, thereby realizing the parallel lifting function of the lifter. Therefore, under the drive of the lifting bed lifter, the bed frame can also rise parallel to the bed body. When the bed frame reaches a horizontal and stable state, a distance will be left between the bed frame and the bottom of the bed, so as to facilitate the taking and placing of items or cleaning of the bedside position.

[0013] Furthermore, it also includes a lifting gas spring, the parallel connecting rod is provided with an extension rod along its length direction, the extended end of the lifting gas spring is rotatably connected to the extension rod, and the fixed end of the lifting gas spring is rotatably connected to the fixed plate.

[0014] Therefore, the lifting gas spring is used as the power, no energy is required, and the use cost is low; at the same time, the lifting gas spring makes it labor-saving and noise-free when the bed frame is lifted or lowered, and the structure is stable.

[0015] Furthermore, the second rocker arm connecting rod is longer than the first rocker arm connecting rod.

[0016] Furthermore, a fixing pad is provided on the fixing plate, and a stopper is provided on the fixing pad, and the second rocker arm connecting rod can be abutted against the stopper when being recovered.

[0017] Furthermore, it also includes a washer, which is arranged at the rotation connection between the fixed plate and the second rocker arm connecting rod and the supporting connecting rod.

[0018] Therefore, setting washers can increase the contact area of ​​​​the parts, reduce pressure and prevent loosening.

[0019] Furthermore, the parallel connecting rod is provided with a folded edge, and the folded edge is used to support the lifting bed frame.

[0020] Furthermore, the fixing plate is fixedly mounted on the inner wall of the bed.

[0021] Furthermore, the anti-shake mechanism is a cross bar, and both ends of the cross bar are fixedly connected to the two second rocker arm connecting rods respectively.

[0022] Therefore, by arranging a cross bar between the two second rocker arm links, the second rocker arm links will not shake during the lifting process, thereby improving the stability between the two lifters.

[0023] Furthermore, the load-bearing mechanism is an L-shaped leg, the upper part of the vertical end of the L-shaped leg is connected to the fixing plate, and the horizontal end of the L-shaped leg is supported on the ground.

[0024] Therefore, supporting the horizontal end of the L-shaped leg on the ground can increase the contact area between the leg and the ground, thereby improving the load-bearing capacity of the leg.

[0025] Furthermore, the load-bearing mechanism is symmetrically arranged at both ends of the fixing plate.

[0026] Furthermore, the bed frame is provided with a hook, and the bed body is provided with a fixing block matched with the hook.

[0027] Therefore, when the bed frame is in a horizontal and stable state, the hooks on the bed frame are hooked onto the fixed blocks on the bed body, thereby limiting the movement of the bed frame and further improving the stability of the bed frame.

[0028] Furthermore, the bed frame is provided with a handle.

[0029] Thus, providing the handle makes it more convenient to lift or press down the bed frame.

[0030] Furthermore, a load-bearing block is provided on the bed body.

[0031] Therefore, when the lifter for the lifting bed is in a folded state, the bed frame just abuts against the load-bearing block, thereby reducing the force of the bed frame on the lifter, thereby extending the service life of the lifter.

[0032] In summary, the lifting bed provided by the present invention has the following technical effects:

[0033] 1) The lifting bed of the present invention has lifters for the lifting bed on both sides of the bed body. The two sets of lifters can drive the bed frame to move at the same time, which not only makes the lifting of the bed frame more stable, but also the two sets of lifters can jointly bear the weight of the bed frame, which is very important for lifting a solid wooden bed board. By providing an anti-shake mechanism between the two sets of lifters, the stability between the two lifters can be improved, so that the lifting bed frame will not shake during the parallel lifting process; by providing at least one load-bearing mechanism under the fixed plate, and the bottom end of the load-bearing mechanism is supported on the ground, the ground support can be used to give the fixed plate sufficient bearing force to ensure that the fixed plate is not easily damaged, thereby extending the service life of the lifter for the lifting bed.

[0034] 2) The lifting bed of the present invention realizes the parallel lifting function of the lifter by driving the connecting rod lifting mechanism until a triangular support structure is formed between the parallel connecting rod, the first rocker connecting rod, the second rocker connecting rod and the lifting gas spring in the connecting rod mechanism. Therefore, under the drive of the lifter, the bed frame can also rise parallel to the bed body. When the bed frame reaches a horizontal and stable state, a distance will be left between the bed frame and the bed bottom, so as to facilitate the taking and placing of items or cleaning of the bedside position.

[0035] 3) The lifting bed of the present invention uses a lifting gas spring as the power of the lifting device, which does not require energy and has low cost. At the same time, the use of the lifting gas spring makes it labor-saving and noise-free when lifting or lowering the slat frame, and the structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0047] Embodiment 1

[0048] See also Figure 1-4 The present invention first discloses a lift 1 for a lifting bed, which comprises a fixed plate 11 and a connecting rod lifting mechanism 12, wherein the connecting rod lifting mechanism 12 comprises a parallel link 121, a first rocker link 122, a second rocker link 123 and a supporting link 124 which are hinged to each other; one end of the second rocker link 123 is hinged to the fixed plate 11, and the other end is hinged to one end of the first rocker link 122; in this embodiment, the length of the second rocker link 123 is longer than that of the first rocker link 122; the other end of the first rocker link 122 is hinged to one end of the parallel link 121; the two ends of the supporting link 124 are respectively hinged to the parallel link 121 and the second rocker link 123; in this embodiment, since the length of the parallel link 121 is longer, one end of the supporting link 124 is hinged to a position close to the middle of the parallel link 121, rather than to the end of the parallel link 121. Finally, the parallel link 121, the first rocker link 122, the second rocker link 123 and the support link 124 are connected to form a closed four-bar linkage. In addition, a lifting gas spring 125 is provided between the fixed plate 11 and the parallel link 121. In this embodiment, the extended end of the piston rod of the lifting gas spring 125 is hinged to the end of the parallel link 121, and one end of the pressure cylinder of the lifting gas spring 125 is hinged to the fixed plate 11.

[0049] See also Figure 1, a fixing pad 111 is provided near the end of the fixing plate 11, and a stopper 1111 is vertically provided on the fixing pad 111, and the second rocker arm connecting rod 123 can be against the upper surface of the stopper 1111 when it is recovered. A load-bearing mechanism 13 is also fixedly connected to the lower part of the fixing plate 11 symmetrically, and the bottom end of the load-bearing mechanism 13 is supported on the ground. In this embodiment, the load-bearing mechanism 13 is an L-shaped leg; the upper part of the vertical end of the L-shaped leg is connected to the fixing plate 11, and the horizontal end of the L-shaped leg is supported on the ground. By setting the load-bearing mechanism 13, the ground support can be used to give the fixing plate 11 sufficient load-bearing force, ensuring that the fixing plate 11 is not easily damaged, thereby extending the service life of the lifter. In addition, a washer 14 is also provided at the hinge between the fixing plate 11 and the second rocker arm connecting rod 123 and the supporting connecting rod 124. By setting the washer 14, the contact area of ​​each part can be increased, the pressure can be reduced, and loosening can be prevented.

[0050] See also Figure 2 When the bed lifter 1 in this embodiment is in a folded state, the lifting gas spring 125 is in a contracted state, and the second rocker arm connecting rod 123 just rests against the upper surface of the stopper 1111 of the fixing pad 111.

[0051] See also Figure 3 The action of the lifting device 1 for the lifting bed in this embodiment to tilt and rise is described as follows:

[0052] An upward force is applied to the parallel connecting rod 121, the piston rod of the lifting gas spring 125 in the compressed state is extended, the supporting connecting rod 124 rotates around the hinge point with the fixed plate 11 and tilts up, and at the same time drives the first rocker arm connecting rod 122 to rotate around the hinge point with the second rocker arm connecting rod 123, and the parallel connecting rod 121 connected to the extended end of the piston rod of the lifting gas spring 125 is lifted up and tilts up, thereby realizing the tilting and rising function of the lifter.

[0053] See also Figure 4 The parallel rising action of the lifting device 1 for the lifting bed in this embodiment is described as follows:

[0054] A rightward force is applied to the parallel link 121, thereby destroying the horizontal state of the second rocker link 123. The second rocker link 123 rotates and rises, driving the first rocker link 122 and the parallel link 121 to rise until the first rocker link 122 and the parallel link 121 are close to a collinear state. At this time, a triangular support structure is formed between the parallel link 121, the first rocker link 122, the second rocker link 123 and the lifting gas spring 125, thereby realizing the parallel lifting function of the lifter.

[0055] Embodiment 2

[0056] See also Figure 5The present invention also provides a lifting bed, including a bed body 2, a bed frame 3 and a lifting bed lifter 1 in the first embodiment. The top of the bed body 2 is provided with an opening, so that the bed body 2 forms a storage cavity 21, and the bed frame 3 can open or close the storage cavity 21 under the drive of the lifting bed lifter 1. In this embodiment, the bed body 2 is a rectangular frame, which is surrounded by four rectangular wooden boards spliced ​​together; the lifting bed lifter 1 has two groups, wherein the fixing plates 11 thereof are symmetrically fixedly mounted on the left and right inner walls of the bed body 2; the folded edges 1211 on the parallel connecting rods 121 of the lifter are fixedly connected to the lower surfaces of the left and right side frames of the bed frame 3 respectively. The two groups of lifting bed lifters 1 that are symmetrical on the left and right can jointly drive the bed frame 3 to move, which not only makes the lifting of the bed frame 3 more stable, but also the two groups of lifters can jointly bear the weight of the bed frame 3. In addition, since the lifting device 1 for lifting bed has the functions of inclined ascent and parallel ascent, the bed frame 3 can also be inclined ascent and parallel ascent relative to the bed body 2 under the drive of the lifting device 1 for lifting bed. In addition, a handle 32 is also provided at one end of the bed frame 3. In this embodiment, the handle 32 is a rope; when it is necessary to take or place items, the handle 32 on the bed frame 3 is dragged upward to lift the bed frame 3, so that the bed frame 3 can be inclined and ascended relative to the bed body 2. When it rises to the limit position, there will be a distance between the bed frame 3 and the bed body 2, so that the storage cavity 21 on the bed body 2 can be taken and placed. When it is necessary to clean the head of the bed, the handle 32 on the bed frame 3 is dragged to the right to move the bed frame 3 to move the bed frame 3 in parallel relative to the bed body 2. When it reaches a horizontal stable state, a distance will be left between the bed frame 3 and the head of the bed, so that it is convenient to clean.

[0057] In addition, an anti-shake mechanism 24 is fixedly connected between the two sets of lift bed lifts 1. In the present embodiment, the anti-shake mechanism 24 is a cross bar, and the two ends of the cross bar are respectively fixedly connected to two symmetrical second rocker arm links 123. By setting a cross bar, the second rocker arm links 123 will not shake during the rising process, thereby improving the stability between the two lifts.

[0058] In addition, a hook 31 is provided on the bed frame 3, and a fixing block 22 cooperating with the hook 31 is provided on the right inner wall of the bed body 2. When the bed frame 3 rises parallel to a horizontal stable state, that is, a triangular stable supporting structure is formed between the parallel connecting rod 121, the first rocker arm connecting rod 122, the second rocker arm connecting rod 123 and the lifting gas spring 125, the hook 31 on the bed frame 3 can be hooked to the fixing block 22 on the bed body 2, thereby limiting the bed frame 3 from continuing to move and improving the stability of the bed frame 3.

[0059] In addition, a plurality of load-bearing blocks 23 are provided on the inner side wall of the bed body 2. When the lifting device 1 for the lifting bed is in a folded state, the bed frame 3 just abuts against the load-bearing blocks 23, thereby reducing the force of the bed frame 3 on the lifting device and extending the service life of the lifting device.

[0060] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
