Description
- This application is a Continuation of and claims the benefit of priority to co-pending U.S. non-provisional patent application Ser. No. 12/798,497 filed Apr. 5, 2010, the entire disclosure of which is hereby incorporated herein by this reference.
- The invention relates generally to the field of beds. More particularly, the invention relates to bed frames and mattresses.
- Conventional beds found in homes include a four-post frame supporting a rigid innerspring or so-called “box-spring” mattress and a more yielding and softer mattress thereabove, sometimes integral therewith. Frames conventionally come in a few standard sizes, e.g. double, queen, and king, and in myriad configurations, e.g. convertible couch, sleigh, canopy, futon, and others emphasizing buyer comfort and aesthetics, e.g. dark colors (brown, for example) and/or textured surfaces. Most conventional corner posts or legs are made of closed, tubular, e.g. cylindrical, form (characterized by hollow regions defined by penetrable seams) that extends from a perimeter, innerspring mattress frame to the floor on which the bed rests. Many beds include a complementary frame-attached or -detached headboard or floor-supported drawers set often containing upholstered sections and/or cubbies or other covered or enclosed spaces. Some lower-priced vendors of beds and accessories have been known to give away cheap, size-adjustable metal frames with the purchase of a set of mattresses. Box-spring mattresses are known to create undesirably safe harbors for bedbugs.
- In institutional settings, e.g. homeless shelters, low-income housing, prisons and jails, dormitories, apartments, hospitals, motels and hotels, and the like, high-density and short-term or otherwise turnover-prone use is common. Moreover, many such institutional settings are fraught with infestation by bugs. Invasive, parasitic, and difficult-to-detect (light brown) bedbugs are an especially common pest, and are nearly invisible to the naked eye, especially in their larva stage of development. (Bedbugs used to be eradicated by the use of DDT, now a banned environmentally hazardous material. Thus bedbug infestations are an increasingly common problem. Those of skill in the art will appreciate that the bedbug commonly has been referred to in the alterative as wall louse, mahogany flat, crimson rambler, heavy dragoon, chinche, chilly billy, and redcoat. Scientifically speaking, bedbugs are of the family Cimicidae of the suborder Heteroptera. The most prevalent human predator variety of bedbug is the Cimex Lectularius.) Mature bedbugs and their even tinier larvae notoriously and insidiously harbor in box-spring mattresses, pillows, bedding, and other penetrable and enclosed or other hiding places. Bedbugs are voracious and nocturnal feeders that find a human host on whose blood to engorge in the dark, typically at night, evidence of the presence of which is more often felt (painfully, the next morning, in the'form of bites) than seen.

FIGS. 1 , 2, and 3 collectively illustrate the inventedbed 10 in accordance with one embodiment of the invention,Bed 10 in this embodiment includes a right-rectangular perimeter frame 12 supported by fourcorner legs Frame 12 may be seen to include four open angledrigid members Bed 10 further includes one or more (e.g. two) angled brace supportmembers FIGS. 1 and 2 ).Bed 10 further includes a right-rectangular wiremesh infill expanse 16 extending across and joined around its perimeter to the inside, lower edges of joinedangled members - Those of skill in the art will appreciate that
bed 10 in accordance with one embodiment of the invention is approximately thirteen inches in height, thirty-nine inches in width, and seventy-three inches in length. Of course, these dimensions are nominal and are selected to correspond nominally with a standard bed height (including mattress) and a standard double bed mattress size in terms of width and length. Thus, other dimensions are contemplated as being within the spirit and scope of the invention.Bed 10 may also include a somewhat flexible, preferably solid foam mattress 18 (shown in dashed outline inFIG. 3 ) of nominal five inch or other desired thickness extendable across and supportable byinfill expanse 16, which in turn extends within a perimeter offrame 12 with its outside edges mounted to upper, inwardly extending expanses of the joinedangled frame members - No inner-spring or box-spring mattress is used, in accordance with the invention, for reasons that also will become clear.
- In accordance with one embodiment of the invention,
legs e.g. bed 10 might he designed with a load-bearing capacity of up to 300 pounds or more, e.g. 600 pounds. Also,frame members FIG. 1 and only in part, for the sake of clarity) preferably is formed by weaving coated steel wires in a criss-cross pattern, as is known, preferably with substantially open weave pattern, e.g. on an approximately 1 inch square grid that is approximately 90% open. Those of skill in the art will appreciate that alternative materials having, suitably similar rigidity and durability characteristics are contemplated as being within the spirit and scope of the invention. - Also in accordance with one embodiment of the invention,
angled frame members members members corner legs - Those of skill, in the art will appreciate that in accordance with one embodiment of the invention,
legs frame 12 in both a long and transverse axis of bed 12 (refer toFIGS. 2 and 3 ). Angle θ will be understood to permit plural ones ofbeds 10 to be stacked atop one another (in a generally vertical stacking orientation) for stowing beds away when not in use. Angle θ will also be understood to some extent to determine the vertical stacking density of the plural beds and thus the amount of space between vertically adjacent frames, In accordance with one embodiment of the invention, θ is between approximately three and approximately eight degrees from vertical, and preferably approximately five degrees. Those of skill in the art also will appreciate that the symmetric splay of all four legs downwardly and outwardly from the rectangular frame also provides a relatively open, tapered space or gap between the length of the legs and a mating wall. Thus, even when the bed in this embodiment of the invention is pushed against a wall or into a corner, there is no safe harbor therebetween for bedbug infestations. - Those of skill in the art also will appreciate that in accordance with one embodiment of the invention,
legs FIGS. 2 and 3 . Such a taper gives the legs sufficient rigidity and shear strength and a sufficient upper welding angular extent while lowering the overall weight of the bed and minimizing adjacent legs' overlapping surface area when the beds are stowed in a nominally vertical stack. Those of skill in the art will appreciate that, to avoid safety and discomfort issues, either end of eitherbrace support member FIG. 2 ). -
FIG. 3 shows another feature ofbed 10 that enables more accurate vertical stacking of beds. Within the interior oflegs stops 20 a, 20 b, 20 c, and 20 d that confront and stop the downward movement of an identical bed stacked thereabove. Thus, eachbed 10 when stacked above another bed comes to rest with its stops against the corresponding corners of the lower bed's frame, causing each bed to “stand” above the other at a fixed height and a substantially horizontal orientation thereabove. The stops in accordance with one embodiment of the invention are mounted (as by welding) approximately intermediate the lengths of the legs. This placement of the stops relative to the height of the bed produces a consistent minimum spacing between adjacently vertically stacked beds, thus ensuring there is no harbor for bedbugs in relatively closed or semi-closed regions therebetween. Those of skill in the art will appreciate that stops 20 a, 20 b, 20 c, and 20 d can be made of any suitable size and shape, e.g. triangular or square or pie-wedge shaped, ⅛ inch steel such as that cut and removed frombrace support members - Those of skill in the art will appreciate that alternative placement for the stops is contemplated—wherein higher or lower placement along the legs respectively increases or decreases vertical stacking density. Advantages of using such stops instead of allowing the legs of the stacked beds to interference fit with one another include the fact that parallel planar orientation of the stacked beds is ensured and the fact that the beds are easier to pull apart for quicker deployment and use.
- Thus, the splay and taper of the stop-equipped legs of the invented bed render them relatively strong but relatively lightweight so that they can be readily slid into a desired position, stacked one on top of another, transported from one facility to another, and deployed or stowed e.g. by stacking) as desired without inviting a bedbug invasion into tiny spaces or semi-enclosed regions formed therebetween.
-
FIGS. 4 , 5, 6, and 7 and DETAIL A collectively illustrate a bed in accordance with another embodiment of the invention. Those of skill in the art that identical features between the two embodiments are identically reference-designated, while similar features therebetween are similarly reference-designated using a prime,e.g. bed 10′. -
Bed 10′ includes two nearly identical, narrow, right-rectangularhorizontal frames 22 a and 22 b including four angled steel perimeter frame members and including one or more angled or flat steel brace support members as described generally above with reference to frame 12 ofbed 10. -
Frames 22 a and 22 b are slightly differentially dimensioned in three orthogonal axes such that the smaller of the two frames is finable within a three dimensional enclosure defined by the larger of the two frames for nested stowage ofbed 10′ as shown inFIG. 4 . Alternatively, whenbed 10′ is deployed for use, the twoframes 22 a and 22 b are configured in a proximate, side-by-side arrangement shown inFIGS. 5 , 6, and 7. Descending downwardly at right angles from smaller frame 22 a are taperedlegs legs Legs legs 14 e and 14 f are configured with flat steel of approximately ⅜ inch thickness to compensate for the fact that these legs are not angled. It is this differential configuration that permits smaller frame 22 a to slide underneath and withinlarger frame 22 b in a nested, space-saving combination. -
Frames 22 a and 22 b ofbed 10′ each include one or more (e.g. one)brace support member 12 ae′ and 12 be′, as shown, which may be of flat ⅛ inch formed steel. - In accordance with one embodiment of the invention,
flumes 22 a and 22 b ofbed 10′ are dimensioned to have an approximately ¼ inch clearance. Those of skill in the art will appreciate that other clearances, whether smaller or larger, are contemplated as being within the spirit and scope of the invention. - Unlike the legs of
bed 10, the legs ofbed 10′ are not splayed. This permits frames 22 a and 22 b to be positioned side by side without a substantial lateral gap therebetween. The overall dimensions offrames 22 a and 22 b ofbed 10′ when configured side by side as shown inFIGS. 5 , 6, and 7 are preferably approximately the same as those ofbed 10 described above. Two half-sized (e.g. twin-sized) wiremesh infill expanses 16 a and 16 b (shown only inFIG. 7 and only in part, for the sake of clarity)mattresses 18 a and 18 b (shown in dashed outline inFIG. 5 ) are provided and fit within their respective one offrames 22 a and 22 b.Mattresses 18 a and 18 b can be of different nominal heights and the same compression to accommodate the different heights offrames 22 a and 22 b. Alternatively,mattresses 18 a and 18 b can be of identical nominal height and can be of differential compression effectively to level the plane of the mattresses' upper surface when in use. - Referring now particularly to
FIG. 5 and DETAIL A, in accordance with on embodiment of the invention,bed 10′ includes one or more (e.g. two) latching mechanisms 24 a and 24 b for securingframes 22 a and 22 b in a fixed, side-by-side position. Each of latching mechanisms 24 a and 24 b in accordance with one embodiment of the invention includes a pivotable catch 26 (which may be riveted to one or more oflegs 14 e and 14 f) and acorresponding post 28 which may be welded or otherwise affixed to one or more oflegs post 28 such as stiff steel rod. -
Bed 10′ shown inFIGS. 4-6 and DETAIL A is likewise preferably finished with a powder coating and a light (e.g. white or off-white) color to resist and highlight bugs, as discussed above by reference toFIGS. 1-3 . - Those of skill in the an will appreciate that any suitable mattress for either bed can be provided but that for bug-resistance, a dense foam (e.g. so-called “memory foam”) mattress is believed to be most suitable. This is because such foam mattresses—unlike traditional box-spring and companion upper mattresses—are “seamless.” Seamlessness is important because seams tend to provide bedbugs with an invasion entry point and a harbor within voids or other open spaces within a traditional mattress. In contrast, there are no seams and no such voids in a dense foam mattress. One particular suitable foam mattress is available from Paramount Mattress, Inc, of Los Angeles, Calif., USA. Those of skill in the art will also appreciate that a seam-welded mattress slip cover preferably is used over the foam mattress for the same reason. Of course, suitably alternative mattress and slip cover designs are contemplated as being within the spirit and scope of the invention.
- While such are not illustrated herein, for the sake of clarity, the bottoms of the bed's legs (its feet) can be equipped with removable pads of suitable material such as rubber or plastic so that the feet do not skid across or mar the floor or other support surface.
- Those of skill in the art will appreciate that the smooth finish to the frame and legs of the invented bed in either embodiment makes it more difficult for bugs to climb onto the bed or remain thereon because the bugs can find no purchase. Those of skill in the art also will appreciate that the light-colored (e.g. white or off-white) finish to the name makes any bugs thereon easily discovered. Bedbugs may have various origins, including the possibility that they were brought into the facility on the person or clothes of a guest of the facility. Thus, despite the unlikelihood of a bedbug crawling from the floor onto the invented bed, nevertheless bedbugs may find their way off of a guest or the guest's clothing, across the bedding and/or the mattress and onto the frame where the bedbugs are likely to be spotted (because of their contrasting, color visibility) and where the bedbugs can be eradicated.
- Those of skill in the art will appreciate the invented bed's openness, elegance, and simplicity, quite apart from its utility in resisting bug infestations.
- It will be understood that the present invention is not limited to the method or detail of construction, fabrication, material, application or use described and illustrated herein. Indeed, any suitable variation of fabrication, use, or application is contemplated as an alternative embodiment, and thus is within the spirit and scope, of the invention.
- It is further intended that any other embodiments of the present invention that result from any changes in application or method of use or operation, configuration, method of manufacture, shape, size, or material, which are not specified within the detailed written description or illustrations contained herein yet would be understood by one skilled in the art, are within the scope of the present invention.
- Accordingly, while the present invention has been shown and described with reference to the foregoing embodiments of the invented apparatus, it will be apparent to those skilled in the art that other changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
