Description

TECHNICAL FIELD

[0001] The present invention relates to a bed, in particular to a bed that can be adjusted between different widths to accommodate different sizes of mattress. BACKGROUND

[0002] Known beds are supplied in different widths to accommodate different sizes of mattress, such as single size, double size, queen size, and king size.

[0003] A problem with such known beds is the need for a large number of stock keeping units (SKU) corresponding to the different bed widths to ensure that a customer can purchase a bed of the desired size. In the foregoing example, four SKUs would be required for a bed that can accommodate single size, double size, queen size, and king size mattresses, after which an appropriate amount of storage space is required to store these SKUs.

[0004] A further problem with such known beds relates to transportation logistics. In particular, and for example, a bed that can accommodate a king size mattress requires more space in a vehicle than a bed that can accommodate a super king size mattress. This increased space requirement results in increased transportation costs, since one of the factors that determines transportation costs is the size of the container. This increased space requirement also prevents most consumers from collecting the bed in their own vehicle, since the space available in a non-commercial vehicle is limited, and as a result, these consumers are forced to have their bed delivered, with the associated increase in the overall purchase price of the bed and the inconvenience of having to wait for the delivery.

[0005] It is therefore an object of the present invention to provide a bed that overcomes or at least mitigates the aforementioned problems associated with known beds. SUMMARY

[0006] Accordingly, in accordance with a first aspect of the present invention, there is provided a bed comprising a frame and a mattress support platform configured to support an associated mattress and a person on the mattress, wherein the mattress support platform is laterally adjustable relative to the frame between a retracted position and an extended position, the extended position having a lateral width that is greater than the lateral width of the retracted position.

[0007] Advantageously, providing a bed that can be adjusted to different lateral widths results in a significant reduction in the number of SKUs, since one SKU can be used with different sizes of mattress. Furthermore, a single and reduced packaging size can be used for each SKU. This reduced packaging size results in lower transportation costs and reduces the likelihood of a consumer collecting the bed in their own vehicle.

[0008] Preferably, the mattress support platform comprises one discrete mattress support element, preferably a plurality. Providing a support platform comprising a plurality of discrete mattress support elements enables the support platform to be packaged in a smaller package and then assembled for display purposes at the store or at the customer's end use location, assuming the support platform is a single piece support platform.

[0009] Preferably, the mattress support platform comprises one discrete mattress support element, preferably a plurality. Providing a support platform comprising a plurality of discrete mattress support elements enables the support platform to be packaged in a smaller package and then assembled for display purposes at the store or at the customer's end use location, assuming the support platform is a single piece support platform.

Advantageously, providing a bed that can be angularly adjusted according to the requirements of a person on the mattress, and adjusted in width to accommodate different sized mattresses, further reduces the number of SKUs required.

[0218] In FIG. 1 to FIG. 11 the bed 10 comprises a frame 12 comprising a plurality of leg portions, in this embodiment six leg portions 13a to 13f, to support the bed 10 and hold the frame 12 above a surface S.

[0219] The frame comprises two parallel side rails in the form of left and right tubes 15a, 15b, a foot end rail in the form of a foot end tube 17, and a head end rail in the form of a head end tube 19 and opposite the head end tube 19. The four tubes (tubes 15a, 15b, 17, 19) are made of aluminium and form a rectangular support on which the mattress support platform 14 is fixed. In alternative embodiments, the side rails and end rails need not be tubes and can be open sections such as C or L shaped sections and can be made of an alternative to aluminium, for example steel.

[0220] The mattress support platform 14 supports a mattress (not shown) and is of a fixed type, i.e. the mattress support platform 14 cannot be angularly adjusted relative to the frame 12.

[0221] ​​​One of the four legs (legs 13a, 13b, 13c, and 13d) is positioned at each corner of the frame 12, and one leg (legs 13e and 13f) partially (in this embodiment, centrally) runs along each of the side tubes 15a and 15b to further support them. In an alternative embodiment, for example where the side tubes partially include hinges to allow the tubes (and thus the frame) to fold, two of the legs are positioned below the hinges to provide support. In another alternative embodiment, the bed comprises only four legs, one at each corner.

[0222] The mattress support platform 14 includes a plurality of mattress support elements (nine in this embodiment) in the form of slat assemblies 16. FIG. 1 to FIG. 3 As can be seen, the slat assembly 16 consists of discrete and parallel spaced slats. In this embodiment, the slat assembly 16 is uniformly spaced apart by a distance D of 100 mm in the longitudinal direction L. S In an alternative embodiment, the slat assemblies 16 may be evenly spaced at varying distances, or unevenly spaced. Each slat assembly 16 has a depth D of 100 mm. SA .

[0223] Each slat assembly 16 is elongated, that is, (in the direction of arrow W) has a depth D greater than its length. SA Horizontal width W R (See) FIG. 3 ).

[0224] Each slat assembly 16 includes a central support section, an extension section 30, and a support section. The central support section is in the form of a central support slat 28. The extension section 30 includes a first extension support section in the form of a first extension support slat 30a and a second extension support section in the form of a second extension support slat 30b. The support section is in the form of a sleeve 32. Each slat (slat 28, slat 30a, slat 30b, slat 32) is defined by a profile including a lower straight portion 34 and a curved portion including two curved side portions 38 and a curved upper portion 40. That is, the central support section 28 and the extension support section 30 slats each have at least partially oval cross-sections.

[0225] Each of the slat 28, the slat 30a, the slat 30b, and the sleeve 32 is extruded from aluminum and defined by a hollow cross-sectional profile having a same thickness t, which includes a lower straight portion 34 and a curved portion. The curved portion includes two curved side portions 38 and a curved upper portion 40. In alternative embodiments, the slat 28, the slat 30a, the slat 30b, and the sleeve 32 can have different thicknesses.

[0226] In addition to the first extension support slat 30a, the second extension support slat 30b, and the sleeve 32 having a closed or continuous profile, the central support slat 28, the first extension support slat 30a, the second extension support slat 30b, and the sleeve 32 have a same cross-sectional shaped profile, however the central support slat 28 has an open or non-continuous cross-sectional profile, specifically, the lower straight section 34 of the central support slat 28 includes an opening 35.

[0227] The second extension support slat 30b and the sleeve 32 have a same shaped and sized profile such that they can be slidably positioned inside the central support slat 28.

[0228] In FIG. 4 , the sleeve 32 is secured within and at the free end of the central support slat 28 using an adhesive between the outer surface of the sleeve 32 and the inner surface of the central support slat 28 to prevent lateral sliding movement between the sleeve 32 and the central support slat 28 when the sleeve 32 is installed within the central support slat 28. Alternatively, as further described below, the sleeve is secured within the central support slat via a hole and fastener arrangement (not shown). In another alternative, the sleeve is sized to form an interference fit with the central support slat such that the sleeve cannot slide laterally once installed.

[0229] The second extension support slat 30b is sized such that it can be slidably positioned inside the central support slat 28 during assembly and slidably move within the central support slat 28 in the lateral direction W during operation as will be described below.

[0230] The first extension support slat 30s is sized such that it can slidably move within the sleeve 32 (which is inserted inside the central support slat 28) and the second extension support slat 30b in the lateral direction L during operation as will be described below.

[0231] In FIG. 1 , FIG. 4 and FIG. 5It can be seen that in the retracted position, the first extension support slat 30a is completely housed within the second extension support slat 30b by being inserted inside the second extension support slat 30b, and the first extension support slat 30a partially overlaps the second extension support slat 30b in the transverse direction W by a distance S R and both extension support slats 30a, 30b are completely housed within the central support slat 28 by being inserted inside the central support slat 28. Both extension support slats 30a, 30b partially overlap in the transverse direction W, with the central support slat 28 in the retracted position.

[0232] In FIG. 6 and FIG. 9 to FIG. 11 It can be seen that by inserting the first extension support slat 30a and the second extension support slat 30b inside the central support slat 28 in the extended position, both the first extension support slat 30a and the second extension support slat 30b are completely housed within the central support slat 28.

[0233] In the above embodiments, the profile of each of the slats 28, 30a, 30b, and the sleeve 32 is described as having a profile of substantially the same cross-sectional shape. It will be appreciated that the profile need not be the same, but can vary in shape so as to provide relative sliding motion. It will further be appreciated that the shape and size of the profile is designed to be sufficient to allow sliding motion of the first extension support slat 30a and the second extension support slat 30b in the transverse direction L, but not to allow any significant vertical motion between the first extension support slat 30a and the sleeve 32 and between the second extension support slat 30b and the central support slat 28, to ensure that the first extension support slat 30a and the second extension support slat 30b provide sufficient vertical support when in the extended position as will be described below.

[0234] The central support slat 28 of each slat assembly 16 is secured to each side tube (side tube 15a, side tube 15b) of the frame 12 via a bracket 42. Each bracket 42 is secured to the side tube 15a, 15 via a fastener such as a self-tapping screw (not shown) that is positioned through a hole 44 of the central support slat 28 and a hole 46 of the bracket 42. In alternative embodiments, the central support slat can be secured directly to the side tube of the frame without the need for a bracket.

[0235] Once secured, the first and second extension support slats 30a, 30b can slide relative to the central support slat 28, and thus relative to the frame 12, between a retracted position and an extended position, as described below. The hole 46 has a larger diameter than the hole 44, such that when assembled, the self- threading screw precisely positions the central support slat 28 relative to the bracket 42, and thus relative to the side rail 15a, the importance of which will be discussed below.

[0236] Each of the first and second extension support slats 30a, 30b includes an end cap 48 inserted inside its open free end to close their open sections.

[0237] In the above-described embodiment, the first extension support slat 30a is described as being entirely enclosed inside the second extension support slat 30b, and both extension support slats 30a, 30b are entirely enclosed inside the central support slat 28. In alternative embodiments, the slats need not be entirely enclosed. For example, the first and second extension support slats can have features that protrude beyond or flush with the opening 35 of the central support slat 28. Alternatively, the first extension support slat can include features that protrude through or flush with the opening of the second extension support slat.

[0238] The bed 10 operates as follows.

[0239] In FIG. 1 , FIG. 3 , FIG. 4 , FIG. 5 and FIG. 10 , the bed 10 is shown in a retracted position, in which the second extension support slat 30b and the first extension support slat 30a are entirely retracted and located inside and entirely within the central support slat 28 in the transverse direction W. In FIG. 5 , the slat assembly 16 is shown with each slat (slat 28, slat 30a, slat 30b) and sleeve 32 displaced longitudinally to show their relative transverse positions. In FIG. 10 , the slat assembly 16f, 16g, 16h, 16i with the central support slat 28 removed, the slat assembly 16h with the sleeve 32 removed, the slat assembly 16g with the first extension support slat 30a removed, and the slat assembly 16f with the second extension support slat 30b removed are shown to show their relative positions.

[0240] In the retracted position, the first extension support slat 30a is inserted inside and partially overlaps the second extension support slat 30b in the transverse direction W by a distance S RBoth the extension support strips 30a and 30b are inserted inside and substantially completely overlap with the central support strip 28 in the lateral direction W. It can also be seen that the first extension support strip 30a is inside the sleeve 32, which is fixed inside the central support strip 28.

[0241] In the retracted position, the mattress support platform 14 has a width W. R (See) FIG. 3 and FIG. 10 ).

[0242] exist FIG. 6 , FIG. 9 and FIG. 11 In the middle, the first extension support strip 30a and the second extension support strip 30b have been manually and slidably adjusted laterally in the direction of arrow W to have a width W. E The extended position. In FIG. 11 In the image, the central support strip 32 has been removed to show the sleeve 32, and the positions of the first extension support strip 30a and the second extension support strip 30b are shown.

[0243] The offset snap (not shown in this embodiment) is based on the desired lateral extension width W E The extended support strips 30a and 30b are locked in place relative to the corresponding holes (not shown) on the central support strip 28.

[0244] exist FIG. 6 , FIG. 9 and FIG. 11 In the extended position, compared to the retracted position, the second extended support strip 30b is no longer partially contained within the first extended support strip 30a in the lateral direction. That is, the first extended support strip 30a and the second extended support strip 30b are separated by a distance S in the lateral direction W. E Both the extension support strips 30a and 30b are inserted into the center support strip 28, and the first extension support strip 30a is inserted into the sleeve 32 fixed inside the center support strip 28.

[0245] At the extended position, the load of the mattress and (multiple) people on the mattress (not shown) is supported vertically by the central slat 28, the first extended support slat 30a, and the second extended support slat 30b.

[0246] The dimensional tolerance between the first extension support slat 30a and the sleeve 32 allows for sliding motion, but limits significant vertical motion when under load. Similarly, the dimensional tolerance between the second extension support slat 30b and the central support slat 28 allows for sliding motion of the first and second extension support slats 30a, 30b, but limits significant vertical motion. By limiting vertical movement, by configuring the shape and thickness t of the cross-sectional profile of the extension slats 30a, 30b and the central support slat 28, the mattress support platform can vertically support the load of a mattress and person(s) on the mattress when in the extended position. Typically, the tolerance between the central support slat 28 and the second extension support slat 30b, and the tolerance between the sleeve 32 and the first extension support slat is less than 0.2 mm, preferably less than 0.1 mm. This tolerance is sufficient to allow for relative sliding motion between the first extension support slat 30a and the sleeve 32 and between the second extension support slat 30b and the central support slat 28, but still provides vertical support when the mattress support platform is under the load of a mattress and person(s) on the mattress. In particular, as noted above, the open or non-continuous cross-sectional profile of the central support slat 28 and the precise location of the central support slat 28 on the side tubes 15a, 15b ensures that the required tolerance is achieved to enable sliding motion and provide vertical support.

[0247] In FIG. 9 , it can be seen that the first and second extension support slats 30a, 30b partially overlap the central support slat 28 in the lateral direction W. That is, the first and second extension support slats 30a, 30b are cantilevered when in the extended position. It will be appreciated that in alternative embodiments, the first and second extension support slats can be inserted inside the central support slat, partially or fully housed in the central support slat, or interlocked with the central support slat (but not cantilevered), in particular, the first and second extension support slats can be supported by lateral extension side rails of the bed frame (of the type shown in FIG. 126 ) rather than by the central support slat.

[0248] In the above embodiment, the retracted position corresponds to a mattress support platform having a width W R that can support a single person mattress, and in the extended position corresponds to a mattress support platform having a width W EThe mattress support platform. In an alternative embodiment, the retracted width can support a single mattress, and the extended width can extend to support a double or king-size mattress; the retracted width can support a double mattress, and the extended width can support a king or king-size mattress; or the retracted width can support a king-size mattress, and the extended width can support a king-size mattress. It will be understood that the bed can be adjusted between any lateral width in the retracted and extended positions, and is not limited to supporting single, double, king, and king-size mattresses.

[0249] exist FIG. 9 to FIG. 11 In the middle, the extension support strips 30a and 30b, the central support strip 28, and the sleeve 32 are arranged on a common transverse axis A in both the retracted and extended positions. L The extension support strips 30a, 30b, the central support strip 28, and the sleeve 32 are aligned in the longitudinal direction L.

[0250] exist FIG. 11 In the middle, sleeve 32 is located on the same side of the bed (when observing). FIG. 11 (To the right). In an alternative embodiment, all sleeves may be located on opposite sides, or sleeves may be alternately located on opposite sides of adjacent strips.

[0251] right FIG. 9 (Extended position) and FIG. 1 The comparison of the (retracted position) shows that when the first extended support strip 30a and the second extended support strip 30b of the mattress support platform 14 move between the retracted position and the extended position, the legs 13a to 13f remain stationary.

[0252] It should be understood that the advantage of the above embodiments is that the bed can be configured with a reduced lateral width and extended to a greater width before use. More specifically, the bed can be supplied to distributors and customers with one width and therefore one package size, and extended to a greater width as needed at the customer's final use location (e.g., to support a double, king, or super king size mattress). The extendable bed configuration significantly reduces the number of SKUs required, and the reduced width configuration (which can be extended after delivery) further reduces both the package size and delivery costs, and simplifies storage, if a smaller package size is required. Additionally, the reduced package size allows for transport in smaller vehicles. For example, a bed that can accommodate a super king size mattress can be packaged in the same size package as a bed that can accommodate a single size mattress.

[0253] Furthermore, by carefully designing the cross-sectional profile and thickness of the slats, and by appropriately selecting the material, such as aluminum, the weight of the bed can be reduced, in particular below the weight sensitive cost threshold set by the logistics companies, and thus attract lower shipping and distribution costs.

[0254] In FIG. 12 to FIG. 37 , an alternative bed 110 is shown which is identical to the bed described with respect to FIG. 1 to FIG. 11 , except that the bed 110 is not of the fixed type, that is, the mattress support platform is angularly adjustable with respect to the frame 112, as will be described hereinafter.

[0255] In FIG. 12 , the bed 110 comprises an angularly adjustable mattress support platform 114 and a frame 112.

[0256] The frame 112 comprises first and second sections 112a, 112b on opposite lateral sides of the bed. The first and second sections 112a, 112b are joined by a hinge 113 which allows the frame 112 to be folded together to reduce the length dimension of the bed for packaging and shipping purposes and / or storage purposes, and subsequently unfolded to provide a full length adjustable bed. The first section 112 comprises a foot support section 126 and a thigh support section 124, and the section 112b comprises a back support section 120 and a mattress bend support section 122. An example of such a folding bed is described in WO2017216547. In FIG. 33 , the first section 112a has a lower surface 119 and the second section 112h as a lower surface 121. When the hinge 113 is used to fold the bed 110, the lower surfaces 119, 121 contact each other, thereby protecting the delicate controls, electronics, and actuators (not shown in FIG. 33 ) from potential damage when the bed 110 is stored in the folded position or when the bed 110 is shipped.

[0257] In addition to the frame 112 of the bed being foldable, each of the mattress support sections 118, 120, 122, 124, 126 can be provided as a modular assembly, such that they can be pivotally connected to adjacent mattress support sections 118, 120, 122, 124, 126 and releasably attached to the frame 112 to enable more compact packaging and associated reduction in shipping costs, and subsequently assembled to provide a fully angularly adjustable bed.

[0258] The angle adjustable mattress support platform 114 includes a plurality of mattress support assemblies (mattress support assemblies 116a-116i) arranged in a plurality of mattress support sections in the form of a seat support section 118, a back support section 120, a mattress bend support section 122 between the back support section 120 and the seat support section 118, a thigh support section 124, and a foot support section 126.

[0259] The seat support section 118 is adjacent to both the mattress bend support section 122 and the thigh support section 124 and is angularly fixed relative to the frame 112 and includes a single seat support assembly 116e and a pair of parallel spaced apart side members 127e connected to each other by the seat mattress support assembly 116e.

[0260] The back support section 120 is adjacent to the mattress bend support section 122 and is angularly adjustable relative to the frame 112 and includes three back support assemblies (back support assemblies 116g-116i) and a pair of parallel spaced apart side members (side members 127g-127i) connected to each other by the three back mattress support assemblies (back mattress support assemblies 116g-116i).

[0261] The mattress bend support section 122 is adjacent to both the back support section 120 and the seat support section 118 and is angularly adjustable relative to the frame 112 and includes a single person mattress bend support assembly 116f and a pair of parallel spaced apart side members 127f connected to each other by the mattress bend support assembly 116f. In an alternative embodiment, instead of the single person mattress bend support section 122 being positioned between and adjacent to the back support section 120 and the seat support section 118, two or more mattress bend support sections can be provided between the back support section and the seat support section to further accommodate the bending of the mattress on the mattress support platform as the back support section is raised and lowered.

[0262] The thigh support section 124 is adjacent to both the seat support section 118 and the foot support section 126 and is angularly adjustable relative to the frame 112 and includes two thigh support assemblies (thigh support assemblies 116c-116d) and a pair of parallel spaced apart side members (side members 127c-127d) connected to each other by the two thigh support assemblies 116c, 116d.

[0263] The foot support section 126 is adjacent to the thigh support section 124 and is angularly adjustable relative to the frame 112 and includes two foot support assemblies 116a, 116b and a pair of parallel spaced apart side members (side members 127a-127b) connected to each other by the two foot support assemblies 116a, 116b.

[0264] As in the bed 10 of FIG. 1 to FIG. 11 Each of the mattress support assemblies 16a-16i includes a central support slat 127 secured to its respective side rods (side rods 127a-127b, side rods 127c-127d, side rod 127e, side rod 127f, side rods 127g-127i) via a hole and fastener arrangement (not shown).

[0265] The side rods (side rods 127g-127i) of the back support section 120 are pivotally mounted to the side rod 127f of the mattress bend support section 122 via a bearing arrangement 147 (which will be described in more detail below), such that the back support section 120 is pivotally mounted relative to the mattress bend support section 122 to allow for relative angular adjustment between the back support section 122 and the mattress bend support section 122.

[0266] The side rod 127f of the mattress bend support section 122 is pivotally mounted to the side rod 127e of the fixed seat section 118 via a bearing arrangement 145 (which will be described in more detail below), such that the mattress bend support section 122 is pivotally mounted relative to the seat support section 118 to allow for relative angular adjustment between the mattress bend support section 118 and the seat support section 118.

[0267] The side rods (side rods 127c-127d) of the thigh support section 124 are pivotally mounted to the side rod 127e of the fixed seat section 118 via a bearing arrangement 143, such that the thigh support section 124 is pivotally mounted relative to the seat support section 118 to allow for relative angular adjustment between the thigh support section 124 and the seat support section 118.

[0268] The side rods (side rods 127a-127b) of the foot support section 126 are pivotally mounted to the side rods (side rods 127c-127d) of the thigh support section 124 via a bearing assembly 149, such that the foot support section 126 is pivotally mounted relative to the thigh support section 124 to allow for relative angular adjustment between the foot support section 26 and the thigh support section 124.

[0269] As in the bed 10 of FIG. 13In the bed 110, a first H-shaped frame includes a pair of side arms 174 and a cross member 176 extending between the arms 174 and partially connecting them along their length. Each of the side arms 174 includes a straight section 174a and a curved section 174b, but it should be understood that the side arm 174 may be fully curved or fully straight. Ball bearings 178 are disposed on a first distal end of each sidewall 174 of the two side arms 174 and are slidably rolled on a track 121 (distributed in side bars 127g to side bars 127i) when the back support section 120 is raised and lowered. The second distal ends of the side arms 174 are pivotally connected to the side tubes 115a, 115b of the frame 112 via a bearing arrangement 139.

[0270] Link 171 connects side arm 174 to a pivot point that connects the side bars (links 127g to 127i) of back support section 120 and the side bar 127f of mattress flexure support section 122. One end of link 171 is pivotally connected to side arm 174 via bearing assembly 150, which is partially positioned along the length of side arm 174. The other end of link 171 is pivotally connected to both the side bars (links 127g to 127i) of back support section 120 and the side bar 127f of mattress flexure support section 122 via bearing assembly 160. Link 171 coordinates movement between back support section 120 and mattress flexure support section 122, as will be described below.

[0271] exist FIG. 16 In the bed 110, a second H-shaped frame (similar to the first H-shaped frame) is included, and a pair of parallel spaced-apart side arms 180 are connected by a cross member 182. Ball bearings 184 are disposed on the free end of each side wall 180 of the side arms 180 and are slidably rolled on a track 131 (located in side bars 127a to 127b of the foot support section). The other free end of the side arm 180 is pivotally connected to the side tubes 115a, 115b of the frame 112 via a bearing assembly 150.

[0272] Link 183 connects side arm 180 to a pivot point that connects the side bars of foot support section 120 (side bars 127a-b) and side bar 127f of mattress bend support section 126. One end of link 183 is pivotally connected to side arm 180 via bearing assembly 150, which is positioned partially along the length of side arm 180. The other end of link 183 is pivotally connected to the side bars of foot support section 126 (side bars 127a-b) and the side bars of thigh support section 124 (side bars 127c-d) via bearing assembly 160. Link 180 coordinates movement between foot support section 126 and thigh support section 124, as will be described below.

[0273] In FIG. 12 to FIG. 16 , bed 110 further includes a first actuator 170 in the form of a linear actuator having a first end (motor and gearbox end) pivotally mounted to a head end 119 of frame 112 and a second end (rod) pivotally connected to cross member 176, relative movement between the first and second ends moving back support section 120 between a lowered position and a raised position, and a second actuator 172 in the form of a linear actuator having a first end (motor and gearbox end) pivotally mounted to a foot end 117 of frame 112 and a second end (rod) pivotally connected to cross member 182, relative movement between the first and second ends moving foot support section 126 and thigh support section 124 between a lowered position and a raised position. In alternative embodiments, the actuators can not be linear actuators. Instead of electrically powered actuators, gas struts can be used to angularly adjust the support sections.

[0274] In FIG. 18 to FIG. 24 , bearing arrangement 147 includes a first bearing assembly 150a and a second bearing assembly 150b.

[0275] The first and second bearing assemblies 150a-b include a bearing 156, a bushing assembly 151a, a bushing assembly 151b, a bearing washer 149a, a bearing washer 149b, and a fastener 153 (which is only shown in FIG. 24 ). Bearing 156 is a conventional ball bearing having an inner race 155 and an outer race 157 separated by balls (not shown) that are rotatably movable relative to one another. Fastener 153 includes a nut 167 and a bolt 165 and a first fastener washer 169a and a second fastener washer 169b. In alternative embodiments, the fastener can be a rivet or any other device that can clamp components together.

[0276] Each bushing assembly (bushing assembly 151a, bushing assembly 151b) includes a first bushing 158 and a second bushing 154 (see FIG. 22 ).

[0277] The bearing washer 149a is axially positioned between and in surface contact with the second bushing 154 of the first bearing assembly 150a and the first bushing 154 of the second bearing assembly 150b.

[0278] The first bushing 158 includes a first axial inward protrusion 161a and the second bushing 154 includes a first axial inward protrusion 161b that is identical to the first axial inward protrusion 161a. The first axial inward protrusion 161a and the second axial inward protrusion 161b limit lateral movement of the second component 127f.

[0279] The first bushing 158 includes a second axial inward protrusion 163a and the second bushing 154 includes a second axial inward protrusion 163b that is identical to the second axial inward protrusion 163a. The first axial inward protrusions 161a, 161b are positioned radially (in the direction of arrow R in FIG. 25 ) outside of the second axial inward protrusions 163a, 163b. The first axial inward protrusions 163a and the second axial inward protrusions 163b engage the inner race 155 to rotationally secure the inner race 155 and the bushing assembly 151 to the first component (first components 127g-127i) using the fastener 153, as will be described below.

[0280] By designing the size of the hole 173 of the side rod 127f, the outer race 157 of the first bearing assembly 150a is rotationally secured to the side rod 127f (second component) of the mattress bend support section 122 such that the outer race 157 forms an interference fit with the outer race 157 of the bearing 156 (see FIG. 19 and FIG. 20 ). Rotationally secured to the side rod 127f means that the outer race 157 of the first bearing assembly 150a cannot rotate relative to the side rod 127f.

[0281] By using the fastener 153 to axially (in the lateral direction W) clamp the side rod 127 (side rods 127g-127i) to the inner race 155 and to at least a portion of the bushing assembly 158 in the form of the first bushing 158, the inner race 155 is rotationally secured to the side rod 127 (side rods 127g-127i) of the back support section 120 (first component), as will be described below.

[0282] The first bearing assembly 150a and the second bearing assembly 150b are axially clamped and secured to each other using fasteners 153. The bolt 167 engages with the side bars (side bars 127g to 127i) (first component) via fastener washer 169a and the nut 165 engages with the bearing washer 149s via fastener washer 169b to clamp and rotationally secure the side bars 123 (side bars 123g to 123i) to the bushing assembly 151 of the first bearing assembly 150a and rotationally secure the bushing assembly 151 of the second bearing assembly 150b to the bushing assembly 150 of the first bearing assembly 150a. The engagement between the bolt 167 and the bolt 165 also clamps and rotationally secures the inner race 155 of each bearing 156 to the respective bushing assembly of the first bearing assembly 150a and the second bearing assembly 150b.

[0283] By determining the hole size of the link, the outer race 157 of the second bearing assembly 150b is rotationally secured to the link 171 (third component) such that the outer race 171 forms an interference fit with the outer race 157 in the same manner as described above with respect to the side bars 127f and the outer race 157 of the first bearing assembly 150a.

[0284] Once clamped together, and when driven by the actuator 170, the side bars 127 to 127i (first component), the side bars 127f (second component), and the link 171 (third component) are free to pivot relative to each other and effect a pivotal movement of the back support section 120 relative to the mattress bend support section 122.

[0285] In FIG. 16 , FIG. 17 and FIG. 25 the bearing arrangement 149 is identical to the bearing arrangement 147 except that the first component corresponds to the side bars 127a to 127b of the foot support section 126, the second component corresponds to the side bars 127c to 127d of the thigh support section, and the third component corresponds to the link 183. When driven by the actuator 172, the side bars 127a, 127b (first component), the side bars 127c, 127d (second component), and the link 183 (third component) are free to pivot relative to each other and effect a pivotal movement of the foot support section 126 relative to the thigh support section 124.

[0286] In FIG. 12 , FIG. 26 and FIG. 27In the case of bearing arrangement 143, it includes only a single bearing assembly in the form of first bearing assembly 150a, which is identical to the bearing assemblies 150a of bearing arrangements 147, 149, except that the first component corresponds to side bars 127c, 127d of foot support section 124 and the second component corresponds to side bar 127e of fixed seat section 118. When actuated by actuator 172, side bars 127cd (first component) and side bar 127e (second component) are free to pivot relative to one another and effect pivoting movement of foot support section 126 relative to fixed seat section 118.

[0287] In the case of bearing arrangement 145, it is identical to bearing arrangement 143, except that the first component corresponds to side bar 127e of fixed seat section 118 and the second component corresponds to side bar 127f of mattress bend support section 122. When actuated by actuator 170, side bar 127e (first component) and side bar 127f (second component) are free to pivot relative to one another and effect pivoting movement of mattress bend support section 122 relative to fixed seat section 118. FIG. 14 FIG. 28 In the case of bearing arrangement 145, it is identical to bearing arrangement 143, except that the first component corresponds to side bar 127e of fixed seat section 118 and the second component corresponds to side bar 127f of mattress bend support section 122. When actuated by actuator 170, side bar 127e (first component) and side bar 127f (second component) are free to pivot relative to one another and effect pivoting movement of mattress bend support section 122 relative to fixed seat section 118.

[0288] In the case of bearing arrangement 139, it is identical to bearing arrangement 143, except that the first component corresponds to side rails 115a, 115b of frame 112 and the second component corresponds to side bracket 174. When actuated by actuator 170, side bracket 174 (second component) can pivot relative to side rails 115a, 115b (first component) and effect pivoting movement of back support section 120 relative to frame 112. FIG. 13 FIG. 29 In the case of bearing arrangement 137, it is identical to bearing arrangement 139, except that the second component corresponds to side bracket 180. When actuated by actuator 172, side bracket 180 (second component) can pivot relative to side rails 115a, 115b (first component) and effect pivoting movement of foot support section 126 relative to frame 112.

[0289] In the case of bearing arrangement 129, it is identical to bearing arrangement 139, except that the first component corresponds to side bracket 174 and the second component corresponds to link 171. When actuated by actuator 170, side bracket 174 (first component) can pivot relative to link 171 (second component) and effect pivoting movement of back support section 120 relative to mattress bend support section 122. FIG. 16 FIG. 30 In the case of bearing arrangement 129, it is identical to bearing arrangement 139, except that the first component corresponds to side bracket 174 and the second component corresponds to link 171. When actuated by actuator 170, side bracket 174 (first component) can pivot relative to link 171 (second component) and effect pivoting movement of back support section 120 relative to mattress bend support section 122.

[0290] In the case of bearing arrangement 129, it is identical to bearing arrangement 139, except that the first component corresponds to side bracket 174 and the second component corresponds to link 171. When actuated by actuator 170, side bracket 174 (first component) can pivot relative to link 171 (second component) and effect pivoting movement of back support section 120 relative to mattress bend support section 122. FIG. 15 FIG. 31 In the case of bearing arrangement 129, it is identical to bearing arrangement 139, except that the first component corresponds to side bracket 174 and the second component corresponds to link 171. When actuated by actuator 170, side bracket 174 (first component) can pivot relative to link 171 (second component) and effect pivoting movement of back support section 120 relative to mattress bend support section 122.

[0291] In​​​​FIG. 16 and FIG. 32 In the above, the bearing arrangement 135 is identical to the bearing arrangement 129 except that the first component corresponds to the side bracket 180 and the second component corresponds to the link 183. When actuated by the actuator 172, the side bracket 180 (first component) can pivot relative to the link 183 (second component) and a pivotal movement of the foot support section 126 relative to the thigh support section 124 is achieved.

[0292] The above bearing assembly is used on a pivotal component of a bed. It will be appreciated that the bearing assembly of the present application is not necessarily limited to a bed but to any adjustable piece of furniture, such as an adjustable chair or an adjustable table, in which at least two components are pivotally linked.

[0293] The bed 110 operates as follows.

[0294] In FIG. 12 , FIG. 13 and FIG. 33 to FIG. 35 , by extension and retraction of the actuator 170, the back support section 120 is moved about the pivot point PP between FIG. 33 the fully lowered flat position and FIG. 34 the partially raised position and then to FIG. 35 the fully raised position. When the actuator 170 is extended, the side arm 174 rotates about the pivotal connection (which is provided by the bearing arrangement 139 on the side rails 115a, 115b) and the ball 178 rolls along the track 121 of the side bar (side bars 127g to 127i) to raise the back support section 120. At the same time, the rotation of the side arm 174 causes the pivotally connected link 171 to rotate and act on the mattress flex support section 118 to cause the mattress flex support section 118 to rotate about the bearing arrangement 147 relative to the back support section 120, that is, about the pivotal connection between the mattress flex support section 118 and the back support section 120. Thus, operation of the actuator 170 drives both by means of the link 171 and the side arm 174 and coordinates the movement between the mattress flex support section 118 and the back support section 120.

[0295] In FIG. 16 and FIG. 33 to FIG. 35 , by extension and retraction of the actuator 172, the foot support section 126 is moved between FIG. 33 the lowered fully flat position and FIG. 34 the partially raised position or intermediate position and then to FIG. 34the side arms 180 rotate about the pivot connection provided by the bearing arrangement 137 on the side rails 115a, 115b and the balls 184 roll along the tracks 131 of the side bars 127a, 127b to raise the foot support section 126. At the same time, the rotation of the side arms 180 causes the pivotally connected link 183 to rotate and act on the thigh support section 124, thereby causing the thigh support section 124 to rotate about the bearing arrangement 149 relative to the foot support section 126, that is, about the pivot connection between the thigh support section 124 and the foot support section 126. Thus, operation of the actuator 172 drives both the thigh support section 124 and the foot support section 126 by means of the link 183 and the side arms 180 and coordinates the movement between the thigh support section 124 and the foot support section 126.

[0296] The bed 110 has the same extension between the retracted position (see FIG. 36 ) and the extended position (see FIG. 37 ). In the FIG. 36 retracted position, the bed 110 is in the retracted position in which the lateral retracted width is defined by the length W R of the central support slat 128 and in the FIG. 37 extended position, the bed 110 is in the extended position in which the free ends of the first and second extended support slats 130a, 130b define an extended width W E .

[0297] In the bed 110, the seat support section 118 is slidingly fixed relative to the frame 112. In alternative embodiments, the bed can be of the "zero wall" type, that is, the position of the person on the mattress support platform remains near the wall against which the head end of the bed can be arranged. This desired "zero wall function" ensures that the position of the person on the mattress relative to the adjacent bed-side furniture is maintained when the back support section is raised and lowered. This "zero wall function" is achieved by fixing the mattress support platform to an intermediate carriage that is slidingly movable in the tracks of the frame of the bed and by fixing the actuator that moves the back support section to the fixed frame of the bed so that when the back support section is raised by the actuator, the mattress support platform moves backwards towards the head end of the bed and when the back support section is lowered by the actuator, the mattress support platform moves forwards towards the foot end of the bed. It will be appreciated that the application described in FIG. 12 to FIG. 121 and FIG. 124 to FIG. 127 can be applied to "zero wall" beds.

[0298] In bed 110, back support section 120, mattress flex support section 122, thigh support section 124, and foot support section 126 are all angularly adjustable. In alternative embodiments, not all support sections need be adjustable, e.g., only the back support section can be adjustable.

[0299] In bed 110, mattress flex support section 122 is disposed between back support section 120 and seat support section 118. In alternative embodiments, back support section 120 can be directly pivotally attached to seat support section 118 without providing mattress flex support section 122.

[0300] In Figures 38 to 40 , an alternative bed 210 is shown that is identical to bed 110 described with respect to Figures 12 to 36 except as described below.

[0301] First and second extension support slats 230a, 230b each have substantially the same width as central support slats 228 to ensure full overlap in the retracted position (see Figure 39 , where slats 228, 230a, 230b are removed from support platform 214 to view their relative positions), extension support slats 230a, 230b do not extend substantially beyond central support slats 228 (without end caps 248), and thus fully overlap central support slats 228 in the lateral direction W.

[0302] In Figure 39 the retracted position, first extension support slat 230a is inserted inside second extension support slat 230b so that it is fully contained within second extension support slat 230b. First extension support slat 230a fully overlaps second extension support slat 230b in the lateral direction.

[0303] From Figure 40As can be seen, when in the extended position (as compared to the bed 10), the first and second extension support slats 230a, 230b partially overlap by a distance O in the transverse direction W. In addition to partially overlapping, the first extension support slat 230a is inserted inside the second extension support slat 230b in the extended position, and is thus fully contained within the second extension support slat 230b. By partially overlapping, and by inserting the first extension support slat 230a inside the second extension support slat 230b, the first and second extension support slats 230a, 230b are considered to be vertically and longitudinally interlocked in the extended position. It will be understood that the first extension support slat need not be fully inserted inside the second extension support slat and still be considered interlocked, so long as the first extension support slat is partially inserted inside the second extension support slat and at least partially overlaps the second extension support slat, such that the first and second extension support slats support each other under the load of a person on the mattress and pad. It will also be understood that in alternative embodiments, interlocking need only provide vertical constraint, and need not be vertical constraint and longitudinal constraint to support the load.

[0304] The support platform 214 of the bed 210 is angularly adjusted between the lowered and raised positions in the same manner as described with respect to the bed 110.

[0305] The transverse width of the support platform 214 of the bed 210 is adjusted in the same manner as described with respect to the bed 110.

[0306] In Figures 41 to 45 an alternative bed 310 is shown that is identical to the bed 110 described with respect to Figures 12 to 37 except as described below.

[0307] The bed 310 includes a plurality of mattress support elements in the form of a plurality of slat assemblies 316. Each slat assembly includes an extension section including a first extension support section 330a including an inner slat 330a 内 and an outer slat 330a 外 and a second extension support section 330b including an inner slat 330b 内 and an outer slat 330b 外 identical to the inner and outer slats of the first extension support section 330a.

[0308] In the retracted position, the inner slats 330a 内 , 330b 内 are inserted inside the outer slats 330a 外 , 330b 外 and the outer slats 330a 外, 330b 外 are inserted inside the central support slats 328. (See Figure 41 Some of the slats are removed to indicate the relative transverse slat positions.

[0309] In the retracted position, the inner slats 330a 内 , 330b 内 are substantially completely transversely accommodated inside the outer slats 330a 外 , 330b 外 , and the outer slats 330a 外 , 330b 外 are substantially completely transversely accommodated inside the central support slats 328.

[0310] Unlike the bed 10, the bed 110, the bed 210, the first extension support section 330a and the second extension support section 330b do not overlap each other in the retracted position.

[0311] In the extended position (see Figure 42 where some of the slats are removed to indicate the relative transverse slat positions and Figure 43 ), the outer slats 330a 外 , 330b 外 have been moved transversely relative to the central support slats 328, and the inner slats 330a 内 , 330b 内 have been moved transversely relative to the outer slats 330a 外 , 330b 外 .

[0312] A comparison of Figure 43 (retracted position) and Figure 44 (extended position) shows that there is no overlap between the first extension support slat 330a and the second extension support slat 330b in the transverse direction L when in the extended position, that is, the first extension support slat 330a is not partially transversely accommodated within the second extension support slat 330b.

[0313] A comparison of Figure 41 and Figure 44 (retracted position) and Figure 42 , Figure 43 and Figure 45 (extended position) shows that the first extension support slat 330a and the second extension support slat 330b are partially accommodated in the central support slats 328 in the transverse direction (direction of arrow W) because the outer slats 330a 外 , 330b 外 are partially accommodated in the central support slats 328 in the transverse direction W.

[0314] The support platform 314 of the bed 310 is angularly adjusted in the same manner as described with respect to the bed 110.

[0315] The lateral width of the support platform 314 of the bed 310 is adjusted in the same manner as described with respect to the bed 110, except that the movement of the first and second extension support slats 330a, 330b is telescoping movement, as each of the two extension support slats 330a, 330b needs to move relative to the outer slat 330a 外 , 330b 外 relative to the center support slat 328, and the inner slat 330a 内 , 330b 内 relative to the outer slat 330a 外 , 330b 外 .

[0316] In Figures 46 to 51 , an alternative bed 410 is shown that is identical to the bed 110 described with respect to Figures 12 to 37 , except as described below.

[0317] The bed includes a support platform 414 that includes a plurality of mattress support elements in the form of slat assemblies 416a-416i.

[0318] The back support section 420 includes an adjustable lumbar support slat assembly 416g, an adjustable neck support slat assembly 416i, and a fixed slat assembly 416h.

[0319] The fixed support slat assembly 416h is fixed at each end to the side rods (side rods 427g-427i) of the back support section 420 in the same manner as in the bed 110.

[0320] The bed 410 also includes a neck support actuator 421 configured to move the adjustable neck support slat assembly 416i, and a lumbar support actuator 423 configured to move the adjustable neck support slat assembly 416i. Both the neck support actuator 421 and the lumbar support actuator 423 are "push only" linear actuators.

[0321] The neck support actuator 421 has a first end (motor and gear box end) pivotally connected to strap 425hi, which is pivotally fixed to the fixed slab 426hi, and a second end (rod) pivotally connected to strap 425i, which is pivotally fixed to the center support slab 428i of the adjustable lumbar support slab assembly 416i, such that relative motion between the first end and second end of the neck support actuator 421 rotates the adjustable lumbar support slab assembly 416i relative to the fixed slab 426hi between a flat position (see Figures 46 to 49 ) and a raised position (see Figure 50 and Figure 51 ).

[0322] The lumbar support actuator 423 has a first end (motor and gear box end) pivotally connected to strap 425h2, which is pivotally fixed to the fixed slab 426hi, and a second end (rod) pivotally connected to strap 425g, which is pivotally fixed to the center support slab 428g of the adjustable lumbar support slab assembly 416g, such that relative motion between the first end and second end of the lumbar support actuator 423 rotates the adjustable lumbar support slab assembly 416g relative to the fixed slab 426hi between a flat position (see Figures 46 to 49 ) and a raised position (see Figure 50 and Figure 51 ). In alternative embodiments, the actuators 421, 423 can be pivotally fixed directly to the side rods (side rods 427g-427i) at the motor and gear box end, rather than indirectly pivotally fixed via straps 425hi, 425h2. Similarly, the actuators 421, 423 can be pivotally fixed directly to the side rods (side rods 427g-427i) at the rod end, rather than indirectly pivotally fixed via straps 425hi, 425h2.

[0323] In Figure 48 and Figure 49In particular, the strips 425g, 425hi, 425h2, 425i have inner cross-sectional profiles that correspond in shape and size to the outer cross-sectional profiles of the support slat assemblies 416g, 416hi, 416i, such that the strips 425g, 425hi, 425h2, 425i can be slidably assembled onto the support slat assemblies 416g, 416hi, 416i, and rotationally fixed to the support slat assemblies 416g, 416hi, 416i onto which the strips 425g, 425hi, 425h2, 425i have been assembled. The strips 425g, 425hi, 425h2, 425i also include holes 427 to enable pivotal connection of the actuators 421, 423.

[0324] In contrast to the beds 110-310, the central support slats 428g on the adjustable lumbar support slat assembly 416g and the central support slats 428i on the adjustable neck support slat assembly 416i are pivotally attached to the side rails (side rails 427g-427i) by using only a single fastener 437 to secure to the side rails (side rails 427g-427i), enabling the adjustable support slat assemblies 416g, 416i to pivot relative to the side rails 427g-427i, in contrast to the use of two fasteners in the beds 10-310 to secure each of the non-adjustable support slats 16, 116, 216, 316 to the side rails 27, 127, 237, 337. In the bed 410, the neck support slats 428i are pivotally attached to the side rails (side rails 427g-427i) at their most forward end (towards the foot end 417 of the bed 410), and rotate towards the foot end 417 when moving from the lowered position to the raised position, and the lumbar support slats 428g are pivotally attached to the side rails (side rails 427g-427i) at their most rearward end (towards the head end 419 of the bed 410), and rotate towards the head end 419 when moving from the lowered position to the raised position. In alternative embodiments, the pivot attachment points of the neck and lumbar support slats on the side rails can be reversed, such that the neck support slats are pivotally attached to the side rails at their most rearward end (towards the head end of the bed), and the lumbar support slats are pivotally attached to the side rails at their most forward end (towards the foot end of the bed). The pivot attachment points (and hence the direction of rotation of the neck and lumbar support slats) are selected to correspond to the respective neck and lumbar regions of the person on the mattress when the person on the mattress is lying on the mattress support platform of the bed.

[0325] When actuated by actuator 421, neck support slat assembly 416i rotates between a flat position and a raised position relative to adjacent fixed support slat 416h and side rails (side rails 127g-i) because fixed support slat assembly 416h is fixed relative to the side rails (side rails 127g-i). Similarly, when actuated by actuator 423, lumbar support slat assembly 416g rotates between a flat position and a raised position relative to adjacent fixed support slat assembly 416h. In alternative embodiments, the neck and lumbar support slats can move linearly, rather than rotationally relative to adjacent fixed support slats between a flat position and a raised position, or a combination of linear and rotational movement.

[0326] It will be appreciated that the rotation of neck support slat assembly 416i is independent of the rotation of lumbar support slat assembly 416g, and that the rotation of neck support slat assembly 416i and lumbar support slat assembly 416g is independent of the angular movement of back support section 420 between the lowered position and the fully raised position. It will also be appreciated that neck support slat assembly 416i and lumbar support slat assembly 416g rotate relative to adjacent support slat assembly 416h disposed on the same support section 420.

[0327] It will be appreciated that the rotation of neck support slat assembly 416i is independent of the rotation of lumbar support slat assembly 416g, and that the rotation of neck support slat assembly 416i and lumbar support slat assembly 416g is independent of the angular movement of back support section 420 between the lowered position and the fully raised position. It will also be appreciated that neck support slat assembly 416i and lumbar support slat assembly 416g rotate relative to adjacent support slat assembly 416h disposed on the same support section 420.

[0328] Bed 410 also includes a mattress retainer 439 that prevents the mattress (not shown) from moving beyond the foot end of the bed substantially in the longitudinal direction L when support platform 414 is raised and lowered.

[0329] In contrast to beds 110-310, the balls 478 roll in slots 421 of the side rails (side rails 427g-i) rather than along tracks of the side rails to lower and raise back support section 420 (see Figure 49 ).

[0330] Support platform 414 of bed 410 angularly adjusts between lowered (see Figure 46 ) and raised (see Figure 51 ) positions in the same manner as described with respect to bed 110.

[0331] Bed 410 moves from a retracted position (see Figure 46 ) to an extended position (see Figure 51 ) in the same manner as described with respect to bed 110.

[0332] It will be understood that adjustable lumbar support slats and adjustable neck support slats can be used in any adjustable bed, wherein separate slats are positioned on the back support section. It will also be understood that adjustable lumbar support slats and adjustable neck support slats can be used in any adjustable bed, and not limited to adjustable beds, wherein the mattress support section is adjustable between a retracted position and an extended position. In a bed (which is described as having no rounded edges as part of its cross-sectional profile), the slats can be modified to include rounded edges, or additional elements can be added such that the modified slats or additional elements with rounded edges smoothly engage with the mattress when moving between a flat position and a raised position.

[0333] exist Figure 51 As can be seen from this, when the bed is in the extended position (see...), Figure 51 Extended foot rails 417E and extended head rails 419E have been added to frame 412 to allow the bed to be in the retracted position (see [link]). Figure 46 Replace foot rail 417 and head rail 419. Head rail 419E and foot rail 417E have a lateral width W at their extended positions. F / H The lateral width is greater than the lateral width W defined by the lateral distance between the left track 415b and the right track 415a when in the retracted position. SR .

[0334] The retracted position in bed 410 corresponds to a mattress support platform that can support a single mattress (3 feet) or a double mattress (4 feet 6 inches), and the extended position corresponds to a mattress support platform that can support any mattress larger than 4 feet 6 inches (5 feet, 6 feet, or 6 feet 4 inches).

[0335] At the extended position (see...) Figure 51 The foot rail 417E and head rail 419E have been extended to a width sufficient to prevent the bed 410 from becoming unstable or tilting under the load of the mattress and the people on it. By tilting, this means that when the maximum expected load of the mattress and the people on it is applied vertically above the legs 413b, 413c on the opposite lateral sides of the bed 410, the legs 413a, 413d on one side of the bed remain in contact with the surface S.

[0336] It will be understood that the extended side rails of bed 410 can be used in Figures 1 to 45 And in Figures 52 to 127 Any of the embodiments described herein.

[0337] exist Figures 52 to 54In some embodiments, an alternative bed 510 is shown that is identical to the bed 410 described in relation to Figures 46 to 51

[0338] Each stabiliser 515a, 515b, 515c, 515d extends laterally outwardly and has a length of typically 6 inches (150mm) that is sufficient to prevent the bed 510 from becoming unstable or tilting under the load of a person on the mattress and mattress(es). By tilting, it is meant that when the maximum expected load of a person on the mattress and mattress(es) is applied vertically over the stabilisers 515b, 515d on the opposite lateral side of the bed 510, the stabilisers 515a, 515c on one side of the bed remain in contact with the surface S.

[0339] It will be appreciated that the stabilisers 515a, 515b, 515c, 515d of the bed 510 can be used on any of the embodiments described in Figures 1 to 51 and Figures 55 to 127 .

[0340] In Figures 55 to 61 , an alternative bed 610 is shown (without legs) that is identical to the bed 110 described in relation to Figures 12 to 37 .

[0341] The bed 610 comprises a plurality of mattress support elements in the form of a plurality of slat assemblies 616. Each slat assembly 616 comprises a central support section in the form of a central support slat 628 and an extension section comprising a first extension support section 630a and a second extension support section 630b.

[0342] The first extension support section 630a comprises a first tube 630al and a second tube 630a2 and the second extension support section 630b comprises a first tube 630bl and a second tube 630b2. Each tube is hollow and has a circular cross-sectional profile. The outer diameter of the first tube 630al, 630bl is less than the inner diameter of the second tube 630a2, 630b2 so that the first tube 630al of the first extension support section 630a can be inserted inside the second tube 630b2 of the second extension support section 630b and the first tube 630bl of the second extension support section 630b can be inserted inside the second tube 630a2 of the first extension support section 630a.

[0343] ​In Figure 56 and Figure 57 , the first extension support section 630a includes a handle 685a that receives and connects the distal end of each of the first and second tubes 630a1, 630a2, and a handle 685b that receives and connects the distal end of each of the first and second tubes 630b1, 630b2. Once connected, the first and second extension support sections 630a, 630b define a U-shaped planar profile.

[0344] Each slat assembly 616 also includes four identical support blocks, two outer support blocks 633a, 633b and two inner support blocks 633a I , 633b I . Each support block 633a, 633a I , 633b, 633b I includes two holes 686 that are sized in diameter to receive the second tubes 630a2, 630b2 of the first and second extension support sections 630a, 630b (see Figures 59 to 61 ).

[0345] Each of the outer support blocks 633a, 633b is fixed to and at each end of the central support slat 628, and the two inner support blocks 633a I , 633b I are fixed to and inward of each end of the central support slat 628 using fasteners (not shown) that, in this embodiment, partially pass through the holes 634 (see Figure 58 ) about one quarter of the distance from each end of the central support slat 628.

[0346] Each of the two inner support blocks 633a I , 633b I is positioned so that, in the extended position (see Figure 61 ), a portion of the first and second tubes 630a1, 630a2 of the first extension support section 630a extends laterally inward and beyond the inner support block 633a I , and a portion of the first and second tubes 630a1, 630a2 of the second extension support section 630b extends laterally inward and beyond the inner support block 633b ITherefore, it can be seen that a portion of the first extended support section 630a and the second extended support section 630b are within the corresponding internal support block (internal support block 633a) of the central support strip 628. I 633b I The extension supports 630a and 630b extend laterally within their respective external support blocks (external support blocks 633a and 633b). It can also be seen that all four tubes 630a2, 630b2, 630a1, and 630b1 of the extended support sections 630a and 630b are completely contained within their respective support blocks 633a and 633b of the central support strip 628. I 633b, 633b I Inside or inside (see) Figure 53 and Figure 55 ).

[0347] At the retracted position (see...) Figure 60 Bed 610 has a lateral width W R It can be seen that the first tube 630a1 of the first extension support section 630a is inserted into and completely contained within the second tube 630b2 of the second extension support section 630b, and the first tube 630b1 of the second extension support section 630b is inserted into and completely closed within the second tube 630a2 of the first extension support section 630a. It can also be seen that a portion of the first extension support section 630a (tubes 630a1, 630a2) and a portion of the second extension support section 630b (tubes 630b1, 630b2) are laterally overlapping. Through this lateral overlap, and with the corresponding tubes of the first extension support section 630a and the second extension support section 630b inserted into each other as described above, the first extension support section 630a and the second extension support section 630b are considered to be interlocked.

[0348] In addition to the first extended support section 630a and the second extended support section 630b being interlocked with each other in the retracted position, a portion of the first extended support section 630a and the second extended support section 630b are located within their respective internal support blocks 633a of the central support strip 628. I 633b I And its corresponding external support blocks 633a, 633b extend laterally inside. It can also be seen that all four tubes 630a2, 630b2, 630a1, 630b1 of the extended support sections 630a, 630b are located within the central support strip 628 and their corresponding support blocks 633a, 633a. I 633b, 633b I Internal (see) Figure 55 and Figure 60 ).

[0349] By pulling handles 685a and 685b until the bed 610 has an extended lateral width W E Up to this point, the lateral width of the support platform 614 of the bed 610 is adjusted in the same manner as described regarding bed 110.

[0350] In Figure 64 and Figure 65 In the middle, the latching assembly 635 includes a latch 637 and a spring 638, the latch 637 being located on the outer support block 633b (in Figure 65 Inside (shown as if the top cover has been removed), the spring 638 biases the latch 637 toward the first tube 630b2 of the second extension support section 630b. Pulling the latch 637 away from the first tube 630b2 disengages the latch 637 from one of the holes 636 in the first tube 630b2, thereby allowing the second extension support section 630a to move relative to the support block 633b of the central support strip 628 and extend its lateral width W as desired. E It engages with another hole 636 in hole 636. The same snap 635 is provided on the outer support block 633b.

[0351] At the extended location (see Figure 61 The first pipe 630a1 of the first extended support section 630a and the second pipe 630b2 of the second extended support section 630b are separated by a lateral distance S. E Furthermore, the first tube 630b1 of the second extended support section 630b is separated from the second tube 630a2 of the first extended support section 630a by a lateral distance S. E This ensures that the first extended support section 630a and the second extended support section 630b do not overlap laterally, and therefore do not interlock at the retracted position.

[0352] At the extended position, a portion of the first extended support section 630a and the second extended support section 630b, at the retracted position, are within their respective internal support blocks 633a of the central support strip 628. I 633b I The corresponding external support blocks 633a and 633b extend laterally inside, such that when the first extended support section 630a and the second extended support section 630b are under the load of the mattress and the person on the associated mat, the support blocks 633a, 633b, and 633a extend laterally inside. I 633b I support.

[0353] The support platform 614 of bed 610 is angle-adjustable in the same manner as described with respect to bed 110.

[0354] exist Figure 66 and Figure 67In

[0355] In contrast to bed 610, only one center support block 733C is provided on the center support slat 728 of the slat assembly 716, instead of two inner support blocks.

[0356] In the extended position (see Figure 67 ), the first tube 730b1 of the second extension support section 630b is inserted inside and fully housed by the second tube 630a2 of the first extension support section 730a. It can also be seen that a portion of the second extension support section 730b (tube 730b1) is laterally overlapping a portion of the first extension support section 730a (tube 730a2). By being laterally overlapping and closed with respect to each other, the first extension support section 730a and the second extension support section 730b are considered to be interlocked with each other in the extended position (in contrast to bed 610) and in the retracted position (as in bed 610).

[0357] It will be appreciated that in contrast to bed 610, when in the extended position, only the center support block 733C is required to support the first extension support section 730a and the second extension support section 730b, due to the fact that the first extension support section 730a and the second extension support section 730b are interlocked.

[0358] In Figures 68 to 76 , an alternative bed 810 is shown, which is identical to bed 710 described with respect to Figure 66 and Figure 67 , but employs a similar telescoping arrangement described with respect to bed 310 to extend the platform 814, as shown in Figures 41 to 45 .

[0359] Bed 810 comprises a plurality of mattress support elements in the form of a plurality of slat assemblies 816. Each slat assembly 816 comprises a center support section in the form of a center support slat 828 and an extension section comprising a first extension support section 830a and a second extension support section 830b.

[0360] The first extension support section 830a comprises an inner section 830a 内 and an outer section 830a 外 , and the second extension support section 830b comprises an inner section 830b 内 identical to the inner section of the first extension support section 830a and an outer section 830b 外 identical to the outer section of the first extension support section 830a.

[0361] The inner section 830a 内830b 内 Each includes two inner tubes, 830a1 and 830b1.

[0362] Outer section 830a 外 830b 外 Each includes two outer tubes, 830a2 and 830b2.

[0363] Each of the inner tube 830a1, inner tube 830b1, inner tube 830a2 and outer tube 830b2 is hollow and has a circular cross-sectional profile.

[0364] The outer diameters of the inner tubes 830a1 and 830b1 are smaller than the inner diameters of the outer tubes 830a2 and 830b2, so that the inner section 830a... 内 830b 内 Can be inserted into outer segment 830a 外 830b 外 internal.

[0365] At the retracted position (see...) Figures 68 to 73 (where the inner and outer sections are separated to indicate their relative lateral positions), bed 810 has a lateral width W. R .exist Figure 72 and Figure 73 As can be seen, the inner tubes 830a1 and 830b1 are inserted into the outer tubes 830a2 and 830b2 and are completely enclosed by the outer tubes 830a2 and 830b2. It can also be seen that the first extended support section 830a and the second extended support section 830b do not overlap, and are separated by a lateral distance S at the retracted position. R And therefore they are not mutually locked (see Figure 71 ).

[0366] Except that the first extended support section 830a and the second extended support section 830b are not interlocked at the retracted position, Figure 62 As can be seen from this, the inner section 830a of the first extended support section 830a and the second extended support section 830b 内 830b 内 Hewai Section 830a 外 830b 外 It is completely contained by the central support slats 828.

[0367] The lateral width of the support platform 814 of bed 810 is adjusted in the same manner as described with respect to bed 610, except that in this embodiment, the movement of the first extended support section 830a and the second extended support section 830b is a telescopic movement, because each of the two extended support sections 830a, 830b requires an outer section 830a. 外, 830b 外 Movement of the outer segments 830a 内 , 830b 内 relative to the inner segments 830a 外 , 830b 外 until the desired extended lateral width W E is obtained.

[0368] In the bed 810, the outer tubes 830a2, 830b2 of the first and second extended support segments 830a, 830b slide within the channels 831 of the central support slats 828, rather than within the support blocks 633 in the embodiment of the bed 610. Thus, the first and second extended support segments 830a, 830b are vertically supported by the central support slats 828.

[0369] In Figure 75 and Figure 76 , each outer tube 830a2, 830b2 houses a catch 833 that engages with a hole 834 of the central support slats 828 to position and releasably lock each outer tube (outer tubes 830a2, 830b2) relative to the central support slats 828. Each inner tube 830a1, 830b1 includes a catch 835 that engages with one of the holes 837 in the outer tubes 830a2, 830b2 to position and releasably lock each inner tube (inner tubes 830a1, 830b1) relative to each outer tube (outer tubes 830a2, 830b2) according to the desired extended lateral width W E desired.

[0370] In the extended position (see Figure 74 and Figure 75 ), the first and second extended support segments 830a, 830a are separated from each other by a lateral distance S E and thus do not laterally overlap and are not interlocked.

[0371] In the extended position, the first and second extended support segments 830a, 830 are partially housed in the central support slats 828 in the lateral direction L because the outer segments 830a 外 , 830b 外 are partially housed in the central support slats 828 in the lateral direction L. Since the outer segments 830a 外 , 830b 外 are completely housed by the central support slats 828, the first and second extended support segments 830a, 830 are completely housed by the central support slats 828.

[0372] The support platform 814 of the bed 810 is angularly adjustable in the same manner as described with respect to the bed 110.

[0373] In Figures 77 to 82 , an alternative bed 910 (without legs) is shown that is identical to the bed 710 except as described below.

[0374] In comparison to the bed 710, the central support block 933c of the slat assembly 916 includes four holes 986 through which the first and second tubes 930a1, 930a2 of the first extension support section 930a and the first and second tubes 930b1, 930b2 of the second extension support section 930b are received (see Figure 79 , with the central support slat 928 removed). The two outer support blocks 933a, 933b also have four holes. Two of the holes 986 of the outer support block 933a receive the first and second tubes 930b1, 930b2 of the second extension support section 930b, and two of the holes 986 of the outer support block 933b receive the first and second tubes 930a1, 930a2 of the first extension support section 930a.

[0375] In the retracted position (see Figure 78 and Figure 79 ), the tubes 930a1, 930a2 of the first extension support section 930a are not located internally and are thus accommodated by the tubes 930b1, 930b2 of the second extension support section 930b. Conversely, the first extension support section 930a and the second extension support section 930b are positioned in different holes of the central support block 933c such that the tubes 930a1, 930a2 of the first extension support section are offset or staggered relative to one another in the longitudinal direction W by a distance L S . The first extension support section 930a and the second extension support section 930b are considered to laterally overlap one another by virtue of the staggered arrangement, rather than by inserting one of the first or second extension support sections inside the other of the first or second extension support sections.

[0376] In the extended position (see Figure 81 and Figure 82 ), the first extension support section 930a and the second extension support section 930b do not laterally overlap one another and are separated by a lateral distance S EThus, the first and second extension support sections 930a, 930b are not interlocked, and thus, the first and second extension support sections 930a, 930b are supported only by engagement with the central support block 933c and the two outer support blocks (outer support blocks 933a, 933b).

[0377] In Figures 83 to 86 an alternative bed 1010 is shown that is identical to bed 110 except as described below.

[0378] The slat assembly 1016 includes end caps 1048 that are inserted into the free open ends of the first and second extension support sections 1030a, 1030b and includes an integrated link 1050.

[0379] The link 1050 includes a hole 1052 toward one end and a protrusion 1054 toward the other end. The protrusion 1054 is sized so that it can sit inside the protrusion 1054 of an adjacent end cap 1048' and enable pivotal movement between the two adjacent end caps (end caps 1048, 1048') and the adjacent extension sections 1030a, 1030b into which they are inserted.

[0380] In Figures 87 to 96 an alternative bed 1110 (without legs) is shown that is identical to bed 110 except as described below.

[0381] The mattress support platform 1114 includes a plurality (5 in this embodiment) of mattress support elements in the form of slat assemblies (slats 1116a-1116e). In contrast to beds 110-1010, each of the mattress support sections (1118, 1120, 1122, 1124, 1126) includes only one of the slat assemblies 1116a-1116e.

[0382] Each slat assembly 1116 includes a central support section in the form of a central support slat 1128, an extension section including a first extension support section in the form of a first extension support slat 1130a, a second extension support section in the form of a second extension support slat 1130b, a first face panel, and a second face panel. The first and second face panels 1132a, 1132b are identical and are typically made of a rigid material such as plywood with a thickness of about 4 mm. Each of the central support slats 1128 is fixed at each end to a parallel side rod 1127 on the respective support section in the same manner as in bed 110.

[0383] The first extension support slat 1130a is dimensioned so that it can be inside and slide within the second extension support slat 1130b. Both the first extension support slat 1130a and the second extension support slat 1130b are dimensioned so that they are inside and slide within the central support slat 1128.

[0384] The first panel 1132a is fixed to the first extension support slat 1130a and the second panel 1132b is fixed to the second extension support slat 1130b, so that sliding of the first extension support slat 1132a and the second extension support slat 1132b relative to the central support slat 1128 moves the first panel 1132a and the second panel 1132b in opposite lateral directions from a retracted position (see Figures 87 to 89 ) to an extended position (see Figures 91 to 96 ).

[0385] In both the retracted position and the extended position, the first panel 1132a and the second panel 1132b are not vertically aligned (in the direction of arrow V) so that the first panel 1132a is positioned on top of the second panel 1132b and so that both panels 1132a, 1132b can slide relative to each other (see Figure 88 ).

[0386] In the retracted position, the first panel 1132a and the second panel 1132b overlap laterally at their free ends so that the free end of the first panel 1132a extends laterally outside the free end of the second panel 1132b and the other free end of the second panel 1132b extends laterally outside the other free end of the first panel 1132a, both lateral extension distances being SPR (see Figure 87 and Figure 88 ).

[0387] In the retracted position (see Figures 87 to 89 ), the first extension support slat 1130a is inserted inside and overlaps laterally the second extension support slat 1130b so that the first extension support slat 1130a and the second extension support slat 1130b interlock with each other.

[0388] The bed 1110 is moved from the retracted position to the extended position in the same way as described with respect to beds 10 to 1010, except that the user directly pulls the panels 1132a, 1132b.

[0389] In the extended position (see Figures 91 to 96), the first and second extension support slats 1130a, 1130b do not overlap laterally with each other and diverge a lateral distance S at their free ends, so the first and second extension support slats 1130a, 1130a are not interlocked and are thus vertically supported only by engagement with the central support slat 1128.

[0390] In the extended position (see Figure 95 ), the inner free ends of the first and second panels 1132a, 1132b overlap laterally by a distance SPE.

[0391] The support platform 1114 of the bed 1110 is angularly adjustable in the same manner as described with respect to the bed 110.

[0392] It will be appreciated that in the bed 1110, each of the support sections 1118, 1120, 1122, 1124, 1126 includes a single panel spanning the longitudinal length L, rather than the beds 110-1010 (except for the fixed seat support section), which include multiple longitudinally spaced slats on each support section.

[0393] It will also be appreciated that in the bed 1110, the seat support section 1118, the mattress bend support section 1122, and the thigh support section 1124 are each supported and extended by a single central support slat 1128 and extension support slats 1130a, 1130b, whereas the back support section 1120 and the foot support section 1126 are supported and extended by two central support slats 1128 and two extension support slats (extension support slats 1130a, 1130b) (see Figure 91 and Figure 92 ). In alternative embodiments, one or all of the support sections can be supported and extended by a single or two central support slats and extension support slats.

[0394] In Figures 97 to 103 , an alternative bed 1210 (without legs) is shown, which is identical to the bed 1110 except as described below.

[0395] Each slat assembly 1216 includes a central support section in the form of a central support slat 1228, an extension section including a first extension support section in the form of a first extension support slat 1230a, a second extension support section in the form of a second extension support slat 1230b, a first panel 1232a, a second panel 1232b, and a central panel 1232c.

[0396] The center panel 1232c is fixed to the center support slat 1228. As in the bed 1110, the first panel 1232a is fixed to the first extended support slat 1230a, and the second panel 1232b is fixed to the second extended support slat 1230b, such that lateral movement of the first and second extended support slats 1232a and 1232b relative to the sliding outer portion of the center support panel 1232c pulls the first and second panels 1232a and 1232b in opposite lateral directions from the retracted position (see Figures 97 to 100 ) to the extended position (see Figures 100 to 103 ).

[0397] In the retracted position, the first panel 1232a, the second panel 1232b, and the center panel 1232c are not vertically aligned, such that the first panel 1232a is positioned on top of the second panel 1232b, and the second panel 1232 is positioned on top of the center panel 1232, such that all of the panels (panel 1232a, panel 1232b, panel 1232c) can slide relative to one another as they move between the retracted position (see Figures 97 to 100 ) and the extended position (see Figures 101 to 103 ).

[0398] In the retracted position, the first panel 1232a and the second panel 1232b overlap laterally at their inner free ends (see Figure 99 ).

[0399] The bed 1210 moves from the retracted position to the extended position in the same manner as described with respect to the bed 1110, except that the first panel 1232a and the second panel 1232b are pulled such that they move laterally outward relative to the fixed center panel 1232c.

[0400] The support platform 1214 of the bed 1310 is angularly adjusted in the same manner as described with respect to the bed 110.

[0401] In Figures 104 to 108 , an alternate bed 1310 (without legs) is shown that is identical to the bed 1110 except as described below.

[0402] Unlike the beds 1110, 1210, which are made of rigid materials, the first panel 1332a and the second panel 1332b are made of soft materials, such as fabric. Thus, it is not required that each mattress support section (mattress support sections 1318, 1320, 1324, 1326) have a dedicated and separate rigid panel to allow for relative angular motion between adjacent panels. Rather, each of the first panel 1332a and the second panel 1332b is a single piece of fabric material.

[0403] Furthermore, by not having a rigid panel on each support section (support sections 1318, 1320, 1324, 1326), there is no need to have a mattress bending support section between the back support section 1320 and the fixed seat section 1318.

[0404] By moving the first and second extension slats 1330a, 1330b laterally outward relative to the center support slat 1328, the bed 1310 is moved from the retracted position to the extended position in the same manner as described with respect to the bed 1110.

[0405] The support platform 1314 of the bed 1310 is angularly adjusted in the same manner as described with respect to the bed 110.

[0406] In Figures 109 to 111 , an alternative bed 1410 is shown that is identical to the bed 1210 in Figures 89 to 94 except that the first, second, and center panels 1432a, 1432b, 1432c are not made of rigid material but are made of a softer material such as fabric. The bed 1410 is identical to the bed 1310 in the same manner as the bed 1110 is identical to the bed 1210, except as described below.

[0407] The bed 1410 is moved from the retracted position to the extended position in the same manner as described with respect to the bed 1210.

[0408] The support platform 1414 of the bed 1410 is angularly adjusted in the same manner as described with respect to the bed 110.

[0409] In Figures 112 to 121 , an alternative bed 1510 is shown that is identical to the bed 610 in Figures 55 to 65 except as described below.

[0410] Each slat assembly 1516 includes a center support section in the form of a center support slat 1528 and an extension section including a first extension support section 1530a, a second extension support section 1530b, and a cross tube 1531.

[0411] The first extension support section 1530a includes two hollow circular tubes 1530al that are parallel and spaced apart, and the second extension support section 1530b includes two hollow circular tubes 1530a2 that are parallel and spaced apart that are extruded from plastic. The tubes 1530al of the first extension support section 1530a have an outer diameter that is less than an inner diameter of the tubes 1530bl of the second extension support section 1530b, to enable the first extension support section 1530a to be inserted inside the second extension support section 1530b.

[0412] In Figures 114 to 117 the central support slats 1528 are supported by plastic extrusion and defined by a hollow cross-section that includes a reinforcing rib 1555, a pair of parallel spaced apart circular through-hole apertures 1533 sized to receive the tubes 1530bl of the second extension support section 1530b, and a partial circular recess 1534 sized to receive the cross tube 1531. Each central support slat 1528 is fixed to the side members 1527 at either end thereof.

[0413] In the retracted position (see Figures 103 to 107 ), the tube 1530al of the first extension support section 1530a is inserted inside and fully contained by the tube 1530b2 of the second extension support section 1530b. It can also be seen that a section (tube 1530al) of the first extension support section 1530a is laterally overlapping a section (tube 1530b2) of the second extension support section 1530b. By being laterally overlapping, and one tube inserted inside the other, the first extension support section 1530a and the second extension support section 1530b are considered to be interlocked with each other.

[0414] The lateral width of the support platform 1514 of the bed 1510 is adjusted in the same manner as described with respect to the bed 110.

[0415] In the extended position (see Figures 118 to 121 ), the end of the first tube 1530al of the first extension support section 1530a is laterally overlapping the second tube 1530b2 of the second extension support section 1530b, the lateral distance of the lateral overlap being O. In addition, the tube 1530al of the first extension support section 1530a remains inserted inside and fully contained by the tube 1530b2 of the second extension support section 1530b, such that the first extension support section 1530a and the second extension support section 1530b are interlocked in the extended position. In alternative embodiments, the first and second extension support sections do not need to be interlocked in the extended position to provide the necessary vertical support.

[0416] The support platform 1514 of the bed 1510 is angularly adjusted in the same manner as described with respect to the bed 110.

[0417] In Figure 122 and Figure 124In the alternative bed 1610 (without legs), which is identical to bed 1110, the mattress support platform 1614 cannot be angularly adjusted in the same manner as the mattress support platform of bed 10 is angularly adjustable. In contrast to bed 110, where first and second panels are disposed over each mattress support section to enable angular adjustment between the mattress support sections, the mattress support platform 1614 of bed 1610 includes only a single first panel 1632a and a single second panel 1632b, which slide relative to one another to move the bed 1610 between a retracted position (see Figure 122 ) and an extended position (see Figure 123 ).

[0418] The alternative bed 1710 is identical to bed 1110 except that the mattress support platform 1714 is covered by a single cover 1732 rather than by separate panels 1132a, 1132b, the cover 1732 being attached to the free outer ends of the first and second extension support sections so that the cover substantially covers the mattress support platform. The cover is folded over itself at the retracted position to create a fold line 1732F so that, in operation, the cover 1732 unfolds as the first and second extension support sections move to the extended width.

[0419] In bed 1710, the cover 1732 is folded twice. It will be appreciated that any number of folds can be used to enable the cover to unfold as the bed moves to the extended position.

[0420] In bed 1710, the mattress support platform 1714 is angularly adjustable. In alternative embodiments, the mattress support platform need not be angularly adjustable (as in bed 10).

[0421] The alternative bed 1810 is identical to bed 410 except that, rather than using head and foot end rails in the extended position at the extended width, the bed 1810 includes head end rails 1819 and foot end rails 1817, which are both capable of extending laterally.

[0422] The head end rail 1819 includes a fixed central section 1819 C and two extension sections 1819 E .

[0423] The foot end rail 1817 includes a fixed central section 1817 C and two extension sections 1817 E .

[0424] The two sections 1817 E , 1819E are able to extend laterally relative to the fixed center section 1817 C , 1819 C to adjust the frame 1812 between a frame retracted position (see Figure 126 ) which corresponds to supporting the mattress in a retracted position and a frame extended position which corresponds to supporting the mattress in an extended position.

[0425] In the frame extended position (see Figure 127 ), the legs 1813 have a greater lateral width than in the frame retracted position (see Figure 126 ) which is sufficient to prevent the bed 1810 from becoming unstable or tipping over under the load of a person on the mattress and pads.

[0426] It will be appreciated that the extended side rails of the bed 410 can be used on any of the embodiments described in Figures 1 to 125 .

[0427] In the bed 1820, the side rails 1815a, 1815d remain stationary when the head end rail 1819 and the foot end rail 1817 extend laterally. In alternative embodiments, the lateral movement of the head end rail and the foot end rail can be fixed to the side rails such that movement of the head end rail and the foot end rail in the lateral direction also moves the left side rail and the right side rail in the lateral direction.

[0428] An alternative bed 1910 is shown in Figures 128 to 143 .

[0429] The bed 1910 is identical to the bed 410 described above in Figures 46 to 51 except for the differences identified below.

[0430] In Figure 129 and Figure 130 (both covers 1928 are removed and the first extended support slat 1930a is moved to the left for clarity), the slat assemblies 1916a-1916i are identical to the slat assemblies 416a-416i except that the extruded aluminum center support slats 1928 include reinforcing ribs 1929 to define closed sections 1930 within the open cross-sectional profile to provide additional rigidity to the aluminum center support slats 1928. The closed sections 1930 include through holes 1944.

[0431] In Figures 130 to 135 , the first extended support slat 1930a and the second extended support slat 1930b differ from the bed 410 in that the first extended support slat 1930a and the second extended support slat 1930b are plastic moldings rather than aluminum extrusions.

[0432] Each of the first and second extension support slats 1930a, 1930b has a cross- sectional profile that enables them to be slidably positioned inside the aluminum center support slat 1928.

[0433] Each of the first and second extension support slats 1930a, 1930b includes a lateral protrusion 1931a, 1931b such that when the bed is in Figure 130 and Figure 132 the retracted position, the lateral protrusion 1931a of the first extension support slat 1930a is positioned inside the corresponding aperture 1932b of the second extension support slat 1930b, and the lateral protrusion 1931b of the second extension support slat 1930b is positioned inside the corresponding aperture 1932b of the second extension support slat 1930b (wherein the first extension support slat 1930a is moved to the left for clarity). In the extended position (see Figure 131 , for clarity, one of the covers 1928 is removed), the lateral protrusions 1931a, 1931b are not positioned inside the corresponding apertures 1932a, 1932b, but it will be appreciated that each lateral protrusion 1931a, 1931b extends the extension support slats 1930a, 1930b by a length to provide more cantilevered support when the bed is in the extended position.

[0434] In Figures 132 to 135 each of the first and second extension support slats 1930a, 1930b further includes an aperture 1933 extending in the lateral direction into which a steel support rod 1934 is inserted to provide additional rigidity to the first and second extension support slats 1930a, 1930b.

[0435] In Figures 140 to 144In particular, each of the first and second extension support slats 1930a, 1930b further includes a plurality of integral clips 1922, the number of which corresponds to the number of lateral bed extension positions. The clips 1922 are integrally molded with the first and second extension support slats 1930a, 1930b and are sufficiently flexible such that when the first and second extension support slats 1930a, 1930b are moved between the preset retracted and extended lateral width positions, the side members 1927e are inside the holes 1923 to releasably hold the first and second extension support slats 1930a, 1930b of the slat assembly 1916e. The first and second extension support slats 1930a, 1930b are released by pressing the clips vertically upward (with the bed in normal use) to disengage the side members 1927e from the holes 1923. It will be understood that the first and second extension support slats of the slat assemblies 1916a-1916i are held in the same manner.

[0436] In Figures 136 to 139 particular, two parallel side support members 1927e are integral with the frame 1912 rather than being integral with separate components 427e connected to the frame 412 (see Figure 51 ).

[0437] The mattress support platform 1914 includes a seat support section 1918, a back support section 1920, a thigh support section 1924, and a foot support section 1926. In contrast to the bed 410, the mattress support platform 1914 does not include a mattress bend support section between the seat support section 1918 and the back support section 1920.

[0438] In contrast to the single slat assembly 416e of the bed 410, the seat support section 1918 includes two slat assemblies (slat assemblies 1916e, 1916f) (see Figure 137 ).

[0439] The slat assembly 1916e is angularly fixed to the side support members 1927e in the same manner as the slat assembly 416e of the bed 410.

[0440] The function of the lumbar slat assembly 1916f is identical to that of the slat assembly 416g, which can rotate relative to adjacent slat assemblies 1916f and 1916g independent of the angle adjustment of the mattress support sections 1918 and 1920. First, the lumbar support assembly 191f is pivotally attached to the side support member 1927e of the seat support section 1918, as compared to the lumbar support slat assembly 416g, which is pivotally attached to the back support section 420. Second, the lumbar support assembly 191f is pivotally attached to the side support member 1927e via the extension brace 1919, and third, the lumbar support assembly 191f pivots in the opposite direction (counterclockwise when viewed from the front of the bed 1940) as compared to the lumbar support assembly 416g. Figure 137

[0441] The lumbar support actuator 1923 has a first end (motor and gear box end) that is pivotally connected to the slat assembly 1916e of the seat support section 1918.

[0442] The neck support slat assembly 1916i is identical to the neck support slat assembly 416i, except that it is pivotally attached to the side support members 1927g-1927i of the back support section 1920 support member 1927e via the extension brace 1919, which is identical to the extension brace 1919 that pivotally attaches the lumbar slat assembly 1816f to the side support member 1927e.

[0443] The provision of the extension brace 1919 moves the hinge point from the slat assembly to the extension brace, and thereby increases the distance that the lumbar support slat assembly 1916f and the neck support slat assembly 1916i can pivot to provide more support (as compared to the lumbar support slat assembly 416g and the neck support slat assembly 416i of the bed 410, which are pivotally connected directly at the hinge point on the side members 427g-427i.

[0444] The neck support actuator 1921 is connected in the same manner as the neck support actuator 421.

[0445] The operation of the bed 1940 is identical to the bed 410, except for the differences identified above.

[0446] In the above-described embodiments, it will be appreciated that the central support section is rigidly connected to parallel side members of each mattress support section, and that the central support section, together with the extension support section, provides direct support to the associated flexible mattress and mat(s) person thereon, without the need for additional support structures (such as rigid (e.g., wood) platforms) between the mattress and the central support section and the extension support section.

[0447] In​Figures 144 to 147 In this regard, it can be seen that for the bed 10, the total area of the mattress support elements 16 in contact with the associated mattress 500 is equal to or greater than the total area defined between the mattress support elements 16 and in contact with the associated mattress 500. This ensures that multiple mattress support elements 16 support the associated mattress. It will be appreciated that not all of the mattress 500 is in contact with the mattress support elements 16 (compare Figure 146 and Figure 147 ), that is, the mattress 500 extends longitudinally and laterally beyond the bed 10 as defined by the mattress support elements 16.

[0448] It will also be appreciated that the central support sections are laterally fixed, that is, they do not need to, and do not, move laterally as the bed moves between the retracted and extended positions. That is, the lateral extent of the bed is provided by the support sections that are being extended.

[0449] By fixing the central support sections to the side members of each mattress support section, the rigidity of the mattress support section is increased, thereby providing more support for the mattress.

[0450] By fixing the central support sections laterally, the mattress is better supported even when the bed is extended laterally.

[0451] In the above embodiments, the adjustable mattress support platform of the bed is made of aluminum, steel, or plastic, or combinations thereof. It will be appreciated that each of the embodiments can be made of aluminum, steel, or plastic, as long as the cross-sectional profile is designed to have sufficient thickness and shape (which can include stiffening sections) to support the load of the mattress and person(s) on the mattress when in the extended position.

[0452] Not all of the above embodiments have been described with reference to a catch that releasably locks the extended support sections in the retracted and extended positions. It will be appreciated that all of the embodiments, whether described or not, can include a catch to releasably lock the extended support sections in the retracted and extended positions, as is known in the art. As an alternative, the central support sections and the extended support sections can be provided with coinciding holes of a pre-set lateral width, and once the desired lateral width is achieved, a releasable fastener (such as a rivet or screw) can be inserted into the coinciding holes to prevent lateral movement between the extended support sections and the central support sections. As another alternative, only the central support sections can be provided with holes through which a fastener, such as a set screw or grub screw, can be inserted to engage with the extended support sections to prevent lateral movement due to friction therebetween.

[0453] In the above embodiments, a seat support section has been described. In alternative embodiments, the bed can not require a seat support section, wherein the mattress bend support section (if present) or the back support section (if the mattress bend support section is not present) is pivotally connected to the upper leg support section, wherein the pivotal connection is provided on and fixed to the side rails of the frame of the bed.

[0454] The above embodiments have been described with and without reference to a leg. It will be appreciated that all of the above embodiments can be used with or without a leg (which is a separate piece of furniture) wherein the frame of the bed is combined with and installed into an existing bed structure such as a bed surround, bed sofa chair or box spring.
