Description
Technical Field
The present invention relates to a bed having a plurality of bed sections, and more particularly, to a bed in which a plurality of bed sections can be folded or stacked one on another to reduce the thickness of the bed for storage or transportation.
Background
The bed includes a platform for supporting a load, such as a human body, and a support assembly mounted below the platform. For transport, some beds are folded to reduce transport size. When the bed is folded, the two portions of the platform are folded over each other, leaving different portions of the support assembly free from the two opposing exterior side surfaces after folding flat. The overall thickness of the folded bed is then greater, and if this thickness can be reduced, the cost of transportation can be reduced.

Detailed Description
Before the embodiments are described in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of embodiments in other forms of implementation. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.
The present invention provides a bed having a plurality of bed sections. The plurality of bed sections are configured to be interconnected to collectively form a complete bed. For storage or transport purposes, the multiple bed sections may be folded or stacked together to reduce the thickness of the bed. Embodiments of the invention will be described in detail with reference to a bed having two bed sections. It will be appreciated that the bed of the invention may also have more than two bed sections.
As shown in fig. 1-6, the present invention provides a bed 10 having a plurality of bed sections that, when folded, have a reduced thickness compared to conventional folding beds. The bed 10 includes a platform and a support assembly for supporting the platform. The bed 10 and its platform define a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The platform is used to support a load, such as a human body. Normally, a mattress is also placed on the platform when in use.
In the illustrated embodiment, the bed 10 includes a first bed section and a second bed section. In the embodiment shown in fig. 1-6, the first bed section and the second bed section are arranged in a longitudinal direction and are rotatably connected to each other. The first bed section comprises a first platform 12 and a first support frame 16 mounted on the bottom side of the first platform 12. The second bed section comprises a second platform 14 and a second support frame 18 mounted on the underside of the second platform 14. Further, the bed 10 further includes a plurality of support legs 20, some of the support legs 20 being removably mounted to the first support frame 16 and some of the support legs 20 being removably mounted to the second support frame 18.
The first platform part 12 and the second platform part 14 together form a platform of the bed 10. The first support shelf 16, the second support shelf 18, and the support legs 20 collectively form a support assembly for the bed 10. That is, the bed 10 may be divided into two bed sections, e.g., a first bed section and a second bed section. The first bed part comprises a first platform part 12, a first support frame 16 and a plurality of support legs 20 arranged on the first support frame 16; the second bed section includes a second platform section 14, a second support frame 18 and a plurality of support legs 20 mounted on the second support frame 18.
The support legs 20 serve as a support structure to support the platform at a predetermined distance from the ground. It will be appreciated that in other embodiments, the support structure may be implemented as other forms of support structures, such as a support frame having height adjustment functionality (e.g., a scissor support). In the embodiment shown, two further support legs 20 are mounted in the middle of the platform. More specifically, two support legs 20 are mounted on a first support frame 16 located in the middle of the platform.
The first platform portion 12 and the second platform portion 14 are rotatable relative to each other between an unfolded position and a folded position. In the deployed position, the first platform portion 12 and the second platform portion 14 together form said platform for carrying a load; in the folded position, the second platform portion 14 is folded to the first platform portion 12 and the first and second support brackets 16, 18 are folded and sandwiched between the first and second platform portions 12, 14. In this case, the overall thickness of the folded bed 10 is the distance between the outer surface of the folded first platform section 12 and the outer surface of the folded second platform section 14. In order to minimize the overall thickness of the bed 10, in the present embodiment, the first support frame 16 and the second support frame 18 are disposed in a staggered arrangement along the transverse direction of the bed 10 so that when the first platform part 12 and the second platform part 14 are folded, the first support frame 16 and the second support frame 18 do not interfere with each other, and the first support frame 16 and the second support frame 18 are completely folded together as much as possible. Thus, after folding, the distance between the opposing interior surfaces (i.e., the lower surfaces when unfolded) of the first platform 12 and the second platform 14 is approximately equal to the thickness of the first support shelf 16 or the second support shelf 18, such that the overall thickness of the folded bed 10 is substantially the sum of the thicknesses of the first platform 12, the second platform 14, and the first support shelf 16 or the second support shelf 18. The folded first platform portion 12 is substantially parallel to the second platform portion 14. The thickness referred to herein means the thickness in the direction perpendicular to the platform.
In the illustrated embodiment, various portions of the bed 10 may be raised to provide a more comfortable position for the user. For example, the platform is shown in a flat configuration in FIG. 1, and a raised head end and raised foot end configuration of the platform is shown in FIG. 2. Specifically, the first platform part 12 includes a first flat plate part 24 and a back rest part 22 rotatably connected to the first flat plate part 24. The second platform portion 14 includes a second platform portion 26, a thigh support portion 28 rotatably connected to the second platform portion 26, and a shank support portion 30 rotatably connected to the thigh support portion 28. The lower leg support 30 is connected to the second brace 18 by a plurality of links 31. Each link 31 has one end rotatably connected to the lower leg support 30 and the other end rotatably connected to the second support frame 18. In this embodiment, the first bed section comprises a first actuator 32 and the second bed section comprises a second actuator 34. A first actuator 32 is connected between the first platform part 12 and the first support frame 16 for driving the first platform part 12 to move relative to the first support frame 16. A second actuator 34 is connected between the second platform portion 14 and the second support bracket 18 for driving the second platform portion 14 to move relative to the second support bracket 18. In the illustrated embodiment, the first actuator 32 and the second actuator 34 are also laterally offset to avoid interference therebetween during folding.
In the illustrated embodiment, there is no direct connection between the first platform section 12 and the second platform section 14. The first support frame 16 and the second support frame 18 are hinged through a hinge, and a rotary connection is only formed between the first support frame 16 and the second support frame 18. The first plate portion 24 is fixed to the first support frame 16 and the second plate portion 26 is fixed to the second support frame 18. Therefore, when the second support frame 18 rotates relative to the first support frame 16, the second platform portion 26 is driven to rotate relative to the first platform portion 24, and thus the first platform portion 12 and the second platform portion 14 are folded.
In some embodiments, the first platform portion 12 may be hinged to the second platform portion 14. In this case, it is not necessary to form a direct connection between the first support bracket 16 and the second support bracket 18. It should be understood that for the folding action, the first platform portion 12 may be pivotally connected to the second platform portion 14, the first support frame 16 may be pivotally connected to the second support frame 18, or both the first platform portion 12 and the second platform portion 14 and the first support frame 16 and the second support frame 18 may be pivotally connected.
In the illustrated embodiment, the first support frame 16 includes two spaced parallel first longitudinal beams 36 and a plurality of first transverse beams 38 connected between the two first longitudinal beams 36. The first longitudinal beams 36 extend in the longitudinal direction of the bed 10 and are spaced apart in the transverse direction of the bed 10. The second support frame 18 includes two spaced parallel second longitudinal beams 40 and at least one second transverse beam 42 connected between the second longitudinal beams 40, the second longitudinal beams 40 extending in the longitudinal direction of the bed 10 and being spaced apart in the transverse direction of the bed 10. In the illustrated embodiment, the lateral distance between the first longitudinal beams 36 is less than the lateral distance between the second longitudinal beams 40 so that the second support shelf 18 avoids the first support shelf 16 when the first and second bed sections are folded over one another, thereby enabling the first and second support shelves 16, 18 to be fully folded together. In other embodiments, the first support bracket 16 may include one first longitudinal beam 36 or more than two first longitudinal beams 36, and correspondingly, the second support bracket 18 may include one second longitudinal beam 40 or more than two second longitudinal beams 40.
Each first longitudinal beam 36 has a first end and the corresponding second longitudinal beam 40 has a second end, the corresponding first and second ends being pivotally connected. The first end of each first longitudinal beam 36 is longitudinally offset from, i.e., not longitudinally aligned with, the second end of the corresponding second longitudinal beam 40. Specifically, a first end of each first longitudinal beam 36 is located and connected inboard of a second end of a corresponding second longitudinal beam 40. When the first support frame 16 and the second support frame 18 are folded, the two first longitudinal beams 36 are located at the inner sides of the corresponding second longitudinal beams 40, so that interference between the first longitudinal beams 36 and the second longitudinal beams 40 is avoided, and the total thickness of the folded bed 10 is reduced as much as possible. The rotational connection between the first and second ends may be achieved in a variety of ways. For example, a pivot hole may be provided in each of the first and second ends, and a connecting pin may be inserted into the pivot holes in the first and second ends to provide the pivotal connection between the first and second ends. This pin and hole connection is easier to achieve with the beam members of the first 16 and second 18 support brackets. If a swivel connection is formed between the first platform part 12 and the second platform part 14, a separate hinge is required. From this perspective, it may be preferred to form a rotational connection between the first support bracket 16 and the second support bracket 18.
Referring to fig. 5, three first transverse beams 38a,38b,38c are connected between the two first longitudinal beams 36. The first transverse beam 38a at the outermost longitudinal side is connected to the ends of the first longitudinal beams 36 remote from the second support frame 18, and the first transverse beam 38c at the innermost longitudinal side is connected to the ends of the first longitudinal beams 36 adjacent to the second support frame 18. The first transverse beam 38b is located between the first transverse beam 38a and the first transverse beam 38 c. The first actuator 32 has one end pivotally connected to the first cross beam 38b and the other end pivotally connected to the back rest portion 22 of the first platform portion 12. The first actuator 32 is capable of controlling the upward lifting of the backrest 22 relative to the first support frame 16. The second transverse beam 42 is connected at both ends of the second longitudinal beams 40 on the side remote from the first support frame 16. The second actuator 34 has one end pivotally connected to the second cross beam 42 and the other end pivotally connected to the thigh support 28 of the second platform part 14. Operation of the second actuator 34 can raise the thigh support and the lower leg support connected thereto.
The number of the links 31 is set to two. Each link 31 has one end pivotally connected to the lower leg support 30 of the second platform section 14 and the other end pivotally connected to the outside of the corresponding second longitudinal beam 40.
In the illustrated embodiment, the second longitudinal beam 40 has a longitudinal length less than the longitudinal length of the first longitudinal beam 36, and the first transverse beam 38a is longitudinally outboard of the second transverse beam 42. An avoiding notch 44 is formed at the end part of each first longitudinal beam 36 close to one side of the first transverse beam 38a, and the position of the avoiding notch 44 corresponds to the position of the second transverse beam 42. When the second support frame 18 is folded onto the first support frame 16, the second transverse beam 42 is just received in the clearance gap 44, and the first transverse beam 38a is located at the outer side of the second transverse beam 42 in the longitudinal direction, so as to avoid interference between the first longitudinal beam 36 and the second transverse beam 42 during folding and interference between the first transverse beam 38a and the second transverse beam 42.
In some embodiments, not shown, the second longitudinal beam 40 may also have a longitudinal length greater than the longitudinal length of the first longitudinal beam 36. At this time, the ends of the two second longitudinal beams 40 may be connected to another second transverse beam, which forms a gap with the aforementioned second transverse beam 42 in the longitudinal direction. When the second support shelf 18 is folded onto the first support shelf 16, the other second cross beam at the end is located beyond the end of the first support shelf 16, and the first cross beam 38a is located in the gap between the two second cross beams, thereby avoiding interference between the second support shelf 18 and the first support shelf 16 during folding.
Referring to fig. 7, in some embodiments, the two first longitudinal beams 36 are entirely offset from the two second longitudinal beams 40 in the transverse direction (the direction indicated by the arrow is the transverse direction), so as to avoid interference between the first support frame 16 and the second support frame 18 during folding. As used herein, "completely misaligned" means that the transverse gap between the first longitudinal beams 36 does not have any overlap in the transverse direction with the transverse gap between the second longitudinal beams 40. In other words, the first longitudinal beams 36 are located on one side of the bed 10 and the second longitudinal beams 40 are located on the opposite side of the bed 10. At this time, the remaining structures of the first and second supports 16 and 18 may be appropriately modified to maintain the support balance of the platform. The first and second brackets 16, 18 may have the same or different widths in the transverse direction.
Fig. 8 illustrates another embodiment of a bed 300 having multiple bed sections. The bed 300 has a first bed section and a second bed section. The first bed section comprises a first platform 312 and a first support frame 316 mounted on the bottom side of the first platform 312. The second bed section includes a second platform section and a second support shelf 318 mounted to the underside of the second platform section 314. The bed 300 may also include several support legs. The remaining structure and connections of the first and second bed sections in the bed 300 may be similar to the previous embodiments, except that the first and second bed sections are connected using at least one connecting rod 350. In the illustrated embodiment, the at least one connecting bar comprises two connecting bars 350 located on either side of the support assembly. Each connecting rod 350 has a first rod portion 354 and an opposite second rod portion 356. The first rod portion 354 is removably mounted to the first support frame 316 and the second rod portion 356 is removably mounted to the second support portion 318, thereby connecting the first and second bed sections to form a complete bed. In the illustrated embodiment, the connecting rod 350 is a straight rod having two rod portions for connecting the first and second support brackets. In some other embodiments, the connecting rod 350 may have any suitable shape and have any number of rods for connecting the first and second support brackets.
As shown in fig. 9, the support structure, such as the connecting rods 350 and any legs, are removed from the first and second support brackets 316, 318, and the first and second bed sections are stacked together with the first and second support brackets 316, 318 sandwiched between the first and second platform portions 312, 314 of the first and second bed sections. The first support frame 316 and the second support frame 318 in the embodiment of fig. 8 and 9 may have the same offset configuration as in the embodiment of fig. 1-7 to minimize the overall thickness of the bed for storage or transport, and therefore the details of this offset configuration are not repeated.
In the above described embodiment, the first platform portion 24 of the first platform portion and the second platform portion 26 of the second platform portion together form a hip support portion that is stationary relative to the support assembly during lifting operations of the backrest portion and thigh/calf support portion. In other embodiments, not shown, the hip support may be completely contained in the first platform portion, or completely contained in the second platform. In this case, the hinge positions between the sections of the platform will change accordingly.
In summary, the present invention provides a bed having a plurality of bed sections which are interconnectable to collectively form a complete bed. The plurality of bed parts may be pivotally connected to each other or connected using another connection system, such as at least one connecting rod. By the staggered arrangement of the first support frame and the second support frame along the transverse direction, when the first bed part and the second bed part are folded or stacked together, the first support frame and the second support frame can not form interference. Thus, the thickness of the bed after folding of the first and second bed sections can be significantly reduced, thereby reducing the packing size of the bed and thus the transport costs of the bed.
The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
