Description
- The present invention pertains, among other things, to bed components, such as mattress foundation frames and components thereof, as well as to systems, methods and techniques for using, setting up, configuring and/or collapsing such components.
- A mattress foundation frame, typically made entirely or substantially entirely of steel or another metal, conventionally has been used to support a mattress foundation (such as a box spring), which in turn supports a mattress. The combination of such a frame, foundation and mattress can be used as a bed. In some cases a separate foundation is omitted, and the mattress is placed directly on top of the upper surface of the frame.
- Different kinds of mattress foundation frames exist. However, improvements remain desirable, particularly with respect to the ease with which such frames (or portions thereof) can be set up, configured and/or collapsed, as well as the maximum sizes/dimensions to which such frames can be collapsed.
- The present invention addresses the foregoing needs, in one respect, by providing a mattress foundation frame that is includes, or is configured to include, one, two or more brackets slidably attached to the rest of the frame which can be used to detachably attach a headboard or a footboard.
- One particular embodiment of the invention is directed to a mattress foundation frame that includes: (a) an upper structure that: (i) is defined by an approximately rectangular perimeter having four corners, and (ii) provides a top surface for supporting a mattress foundation; (b) a plurality of legs attached to the upper structure; (c) two first sliding mechanisms, one provided at each of two adjacent ones the corners; and (d) two headboard/footboard bracket assemblies, each having: (i) a bracket for attaching at least one of a headboard or a footboard, and (ii) a second sliding mechanism that is engaged with the first sliding mechanism of one of the two first sliding mechanisms, such that each of the headboard/footboard bracket assemblies is slidably attached to one of the first sliding mechanisms.
- By virtue of the foregoing arrangement, it can be possible to attach a headboard/footboard bracket only if desired, e.g., if a headboard or footboard is desired to be attached to the frame. Moreover, a configuration according to the present invention often can permit the attachment of such a bracket without the need for tools (e.g., screw drivers or wrenches) or small attachment hardware (e.g., screws, bolts or nuts).
- Another aspect of the present invention is the provision of a mattress foundation frame that can be folded up into a relatively small (e.g., in terms of maximum dimension) package, e.g., for storage and/or shipment.
- One embodiment of this aspect of the invention is directed to a mattress foundation frame that includes: an upper structure that is defined by an approximately rectangular perimeter having two opposite ends and that provides a top surface for supporting a mattress foundation; and a leg assembly attached to the upper structure at each of such two opposite ends. Each such leg assembly preferably includes two legs attached together in a unit and is hingedly attached to the upper structure, so that it is capable of being folded up underneath and substantially parallel to the bottom surface of the top structure or unfolded so that it extends downwardly from, and thereby is capable of supporting, the upper structure. In addition, the upper structure includes two end sections and two middle sections. Each of the end sections is hingedly attached to an adjacent middle section, so that the two sections can be unfolded into an end-to-end configuration or folded so that the bottom surface of the end section is adjacent the bottom surface of the middle section, with the two sections being substantially parallel to each other. The two middle sections are hingedly attached to each other, so that the two sections can be unfolded into an end-to-end configuration or folded so that their bottom surfaces are adjacent to each other and with the two sections being substantially parallel to each other. Preferably, each such leg assembly, when folded up, does not extend beyond the end section to which it is attached. Also, in the preferred embodiments, the two middle sections are hingedly attached through the use of a short intermediate segment that is hingedly attached to each.
- The foregoing summary is intended merely to provide a brief description of certain aspects of the invention. A more complete understanding of the invention can be obtained by referring to the claims and the following detailed description of the preferred embodiments in connection with the accompanying figures.
- In the following disclosure, the invention is described with reference to the accompanying drawings. However, it should be understood that the drawings merely depict certain representative and/or exemplary embodiments and features of the present invention and are not intended to limit the scope of the invention in any manner.

FIG. 1 illustrates an exemplarymattress foundation frame 10 according to the present invention. Other than certain relatively small components, discussed below,frame 10 is made primarily, entirely, or almost entirely (e.g., other than some small portions and/or components), of steel and/or other kind(s) of metal. As shown, theupper structure 11 offrame 10 includes a plurality oflongitudinal slats 12, separated by gaps, andlateral slats 14, also separated by gaps, all surrounded by anouter perimeter 15, that collectively provide a substantially flat (although not continuous) top surface, e.g., for supporting a mattress foundation. That is, in the current embodiment, the top surfaces of theperimeter 15,longitudinal slats 12 andlateral slats 14 are at least approximately coplanar with each other. As shown, theperimeter 15 is approximately rectangular shaped, but with its four corners rounded (e.g., to minimize the likelihood of injury/damage to people or objects).Slats slats 12 are tubular in shape whileslats 14 are rectangular panels. However, in alternate embodiments either or both can have either such shape or even a different shape. - In the current embodiment, the only non-metallic components of
frame 10 are thefeet 16 at the bottom of the legs 17 (i.e.,end legs 17E andmiddle legs 17M), which preferably are made of rubber, plastic or a similar softer material for protecting the surface of the floor upon which frame 10 rests. Alternatively,feet 16 can be omitted, particularly if the bottoms of the legs 17 are formed so as to have only smoothly curved features, in order to avoid scratching or otherwise damaging the floor. As shown in the drawings, in the current embodiment each of the legs 17 is attached to (or otherwise extends from) a different point on theperimeter 15 of theframe 10. In alternate embodiments one or more of thelegs 15 might also extend from the longitudinal and/or lateral slat(s) 12, 14. - One feature of
frame 10, shown most clearly inFIG. 2 , is the inclusion of an inwardly extending mounting structure (sometimes referred to, in reference to the current embodiment, as a corner bracket) 20 at each corner (or at least the two corners at one longitudinal end of frame 10). As shown, in the current embodiment inwardly extendingmounting structure 20 includes: (1) an inwardly extendingshelf 22 that preferably extends at least ½, ¾or 1 inch inwardly away from theperimeter 15 of theframe 10 and preferably is at least approximately coplanar with the top surfaces oflongitudinal slats 12 andlateral slats 14; and (2) a slot-like structure 24 (e.g., at least ½, ¾or 1 inch wide) that extends downwardly (e.g., at least 1 or 2 inches) fromshelf 22. More specifically, in the current embodiment, slot-like structure 24 has a cross-section that is, or approximates, a partial rectangle, with an opening in its inwardly facing long side. In the current embodiment, the entire inwardly extendingmounting structure 20 is welded to the inner edge of the respective corner offrame 10. However, in alternate embodiments,mounting structure 20 is integrally formed with the rest of frame 10 (e.g., at or near one of its corners). - Also provided in the current embodiment is a headboard/
footboard bracket assembly 30 for attaching to one of the corners of frame 10 (e.g., any one of such corners that has a mounting structure 20). As shown, headboard/footboard bracket assembly 30 includes twoelongated panels panels panels panels - In the current embodiment, each of
panels horizontal slots 33, similar to the slots in a conventional headboard or footboard bracket, thereby allowing a standard conventional headboard or footboard to be attached to either ofpanels panels such slots 33 because, in use, typically at most only one ofsuch panels such slots 33 on both ofpanels footboard bracket assembly 30 can be used at any of the four corners offrame 10, thereby reducing the number of different components that must be manufactured. For similar reasons, eachmounting structure 20 is provided at one of the corners of frame 10 (although in alternate embodiments, one or more of such mounting structure is 20 are provided at other locations on the frame 10). - Headboard/
footboard bracket assembly 30 also includes ashelf 34 extending inwardly from the interior surfaces (i.e., the surfaces forming or abutting the smaller angle, which is less than 180° and, more preferably, approximately 90°) ofpanels shelf 34 is welded to such inner surfaces (although in alternate embodiments, it could be integrally formed with, or otherwise attached to, such inner surfaces). Extending upwardly from the distal end of shelf 34 (e.g., at least 1 or 2 inches) is a tab-like structure 36 (e.g., at least ½, ¾or 1 inch wide, but in the current embodiment, slightly narrower than the inner width of slot-like structure 24). Preferably, tab-like structure 36 has a shape that is essentially the same as the interior of slot-like structure 24, but slightly narrower so as to just fit within slot-like structure 24. However, in alternate embodiments, the mating surfaces of mountingstructure 20 and headboard/footboard bracket assembly 30 can have any of a variety of different shapes, e.g., so long as the two can engage with each other, e.g., so that one can slide vertically relative to the other. Thus, for example, in alternate embodiments, a slot-like structure instead is provided on headboard/footboard bracket assembly 30, while a tab-like structure is provided at the corner offrame 10. - In the current embodiment, if a headboard or footboard bracket is desired at a particular location (i.e., corner) on
frame 10, a headboard/footboard bracket assembly 30 is positioned such that tab-like structure 36 is directly beneath slot-like structure 24 and then tab-like structure 36 is slid upwardly into slot-like structure 24, thereby engaging the two components. Preferably, at least one of tab-like structure 36 or slot-like structure 24 is tapered (i.e., narrows in width) as a function of vertical position so that a wedge (or friction) fit is increasingly provided as the two components are more fully engaged with each other. In the current embodiment, as shown in the drawings, slot-like structure 24 (or at least the inner portion thereof) is narrower at the top then at the bottom and tab-like structure 36 (or at least the outer profile thereof) has a uniform width, thereby creating the desired wedge fit. In use, the two components are slid relative to each other in this manner until the top surface ofshelf 34 comes into contact with the bottom surface ofperimeter 15, resulting in a hard stop with respect to relative motion in that direction. The wedge or friction fit provides resistance to relative motion in the opposite direction; it is noted that such inadvertent separating forces typically occur only rarely in normal use. - Also in the current embodiment, the length and other dimensions of headboard/
footboard bracket assembly 30 are such that when fully engaged with mounting structure 20 (e.g., as discussed above), the bottom of headboard/footboard bracket assembly 30 (i.e., the bottom edge ofpanels 31 and 32) extends to the same level as the bottom of legs 17, so that headboard/footboard bracket assembly 30, in addition to providing a headboard/footboard bracket, also functions as an additional leg, providing additional support for theframe 10. As a result, a foot 38 (e.g., L-shaped and made of rubber, plastic or a similar soft material) preferably is provided at the bottom of headboard/footboard bracket assembly 30 in order to protect the floor. - It is noted that the attachment process described above can be repeated for each corner of
frame 10 at which a headboard or footboard bracket might be desired and/or at which an additional leg support is desired. Once a headboard/footboard bracket assembly 30 has been attached to one of the corners of theperimeter 15 in the foregoing manner, a headboard orfootboard 37 can be attached, e.g., by usingscrews 39 which extended through theslots 33, as shown inFIG. 3 . Subsequently, in order to remove a headboard/footboard bracket assembly 30, it is simply pulled away from (i.e., downwardly relative to) the mountingstructure 20 with sufficient force to overcome the friction or wedge fit noted above. - The foregoing embodiment uses inwardly extending tab and slot components. As a result, the outer surface of the corner of
frame 10 can be smooth and/or continuous (e.g., smoothly curved, as shown in the drawings) if a headboard/footboard bracket assembly 30 is not installed at that corner, or if abracket assembly 30 is attached to the corner but a headboard or footboard is not attached tobracket assembly 30. In alternate embodiments, one or more sliding component(s) or similar types of mating component(s) is/are provided on the exterior surface offrame 10 and a corresponding one or more mating and/or sliding component(s) is/are provided on the interior surface of headboard/footboard bracket assembly 30 (e.g., directly onpanel 31 and/or panel 32). While such an alternate embodiment is a more straightforward implementation of the present invention, one potential disadvantage is that the sliding component on the exterior surface of the corner offrame 10 is exposed if a headboard/footboard bracket assembly 30 has not been installed there, possibly resulting in inadvertent scratching or scraping (e.g., of the user's skin and/or of other furniture, walls, etc.). For that reason, the illustrated embodiment currently is preferred. - Variations on the foregoing embodiments are possible. For instance, rather than including a
shelf 22 or 34 (e.g., having a flat top surface) on either or both of mountingstructure 20 or headboard/footboard bracket assembly 30, respectively, any other inwardly extending structure instead may be used. Also, in the preceding embodiments, headboard/footboard bracket assembly 30 attaches to mountingstructure 20 using a friction fit. In alternate embodiments any of a variety of locking mechanisms (e.g., screws, pins, snap-fit mechanisms, spring-loaded latches, etc.) also, or instead, may be used to secure the two components to each other. However, in the preferred embodiments, it is desirable to avoid the use of small mounting hardware (e.g., screws, nuts, pins, etc.) and the necessity of using tools (e.g., screw drivers or wrenches) for attaching or detaching a headboard/footboard bracket assembly 30. - Another aspect of
frame 10 according to the present invention is its unique folding structure which permitsframe 10 to be folded down to approximately ¼of its normal (in-use or operational) length. - In the current embodiment, the
legs 17E at each of the head and the foot of theframe 10 are attached to each other in asingle unit 40 using a cross-bar 42 and are attached to the corresponding end of the frame 10 (more specifically, the corresponding end of the perimeter 15) via hinges 44. In addition, eachsuch end leg 17E is provided with adiagonal support 46 having a pair of hinge pins 47 in its middle section so that it is bendable and also having a locking mechanism 48 (such as a stop or a pin structure) in order to preventsupport 46 from over rotating in the direction in which stress is applied in normal use. As a result of this configuration,such end legs 17E can be folded up against the bottom side of upper structure 11 (shown partially folded up inFIG. 6 and fully folded up inFIG. 7 ) or unfolded into the operational position (shown inFIG. 1 ), as desired. - Also, in the present embodiment the
upper structure 11 itself is divided into four sections 51-54, with adjacent ones of such sections 51-54 so that they can be folded downwardly or inwardly relative to each other, or unfolded so that they are end-to-end. More specifically, in the current embodiment, each ofend sections middle section conventional hinge 57 on each side offrame 10, whilemiddle sections frame 10, a rectangular bar (or other connecting element) 58 with apin 59 at one end attaching the connectingelement 58 tomiddle section 52 and with anotherpin 59 at the other end attaching the connectingelement 58 tomiddle section 53. - As a result of this configuration, the
frame 10 can be folded into approximately one quarter of its operational length in the following manner. First, at each end of theframe 10, each lockingmechanism 48 at that end is released (e.g., by retracting a spring-loaded pin or by rotating the two ends ofsupport 46 away from the stop) and then folding the leg unit 40 (or theindividual end legs 17E, if not attached in the unit) upwardly and inwardly untilsuch end legs 17E contact or are adjacent to and at least approximately parallel with the bottom surface of the upper structure 11 (i.e.,end section 51 or 54), as shown inFIGS. 6 and 7 . In order to accommodate the desired folding, eachleg unit 40 when folded in this manner does not extend beyond the proximal edge of itscorresponding end section end sections 51 and 54 (together with the folded-upleg unit 40 underneath it) is folded upwardly and inwardly (e.g., in the direction 60 shown inFIG. 7 ) so that its bottom surface (and/or the folded-up leg unit 40) contacts or is at least approximately parallel with the bottom surface of the adjacentmiddle section middle sections 52 and 53 (together with the folded-up structures beneath them) are folded in the direction 62 shown inFIG. 7 so as to bring their bottom surfaces together (with themiddle legs 17M between, adjacent to and parallel to their bottom surfaces). The result, shown inFIG. 8 , is a very compact unit that can be easily shipped or stored. - Unfolding such a unit, for operational use of the
frame 10, essentially involves reversing the steps described in the preceding paragraph. Due to the structural features described above, each unfolding operation includes a natural stop so that the two components being unfolded relative to each other are not capable of being rotated beyond their operational configurations. Also, when unfolding the leg unit 40 (or theindividual end legs 17E, if not connected in a unit), thelocking mechanism 48 typically will automatically engage at the operational configuration. However, as noted above, manually actuated stops also or instead may be provided. - As used herein, the term “attached”, or any other form of the word, without further modification, is intended to mean directly attached, attached through one or more other intermediate elements or components, or integrally formed together. In the drawings and/or the discussion, where two individual components or elements are shown and/or discussed as being directly attached to each other, such attachments should be understood as being merely exemplary, and in alternate embodiments the attachment instead may include additional components or elements between such two components. Similarly, method steps discussed and/or claimed herein are not intended to be exclusive; rather, intermediate steps may be performed between any two steps expressly discussed or claimed herein.
- Unless otherwise clearly stated herein, all relative directions (e.g., left, right, top, bottom, above, below) mentioned herein in relation to an article are from the perspective of the article itself and, therefore, are consistent across different views.
- Unless clearly indicated to the contrary, words such as “optimal”, “optimize”, “maximize”, “minimize”, “best”, as well as similar words and other words and suffixes denoting comparison, in the above discussion are not used in their absolute sense. Instead, such terms ordinarily are intended to be understood in light of any other potential constraints, such as user-specified constraints and objectives, as well as cost and processing or manufacturing constraints.
- In the above discussion, certain methods are explained by breaking them down into steps listed in a particular order. However, it should be noted that in each such case, except to the extent clearly indicated to the contrary or mandated by practical considerations (such as where the results from one step are necessary to perform another), the indicated order is not critical but, instead, that the described steps can be reordered and/or two or more of such steps can be performed concurrently.
- In the discussions above, the words “include”, “includes”, “including”, and all other forms of the word should not be understood as limiting, but rather any specific items following such words should be understood as being merely exemplary.
- Several different embodiments of the present invention are described above, with each such embodiment described as including certain features. However, it is intended that the features described in connection with the discussion of any single embodiment are not limited to that embodiment but may be included and/or arranged in various combinations in any of the other embodiments as well, as will be understood by those skilled in the art.
- Thus, although the present invention has been described in detail with regard to the exemplary embodiments thereof and accompanying drawings, it should be apparent to those skilled in the art that various adaptations and modifications of the present invention may be accomplished without departing from the intent and the scope of the invention. Accordingly, the invention is not limited to the precise embodiments shown in the drawings and described above.
