Abstract
Modular convertible furniture systems include a pair of similar open-ended box frame assemblies which are nestable one within the other. A pair of slotted support rails are attached pivotally at respective opposing corners of one of the box frame assemblies so as to be movable between raised and lowered positions. When in a raised position, the rails provide a support for a solid board plank thereby becoming a seat back (e.g., for a chair, love seat, or sofa-type arrangement). When the rails are in a lowered position substantially parallel to the ground, the two box frame assemblies may be oriented back-to-back so as to provide a support for a mattress thereby converting the structure into a bed arrangement, for example. The box frame assemblies can be positioned on different sides and ends thereby allowing formation of tables and/or shelving as may be desired.
Description
- The present invention relates generally to convertible furniture. In a particularly preferred form, the present invention is embodied in a convertible furniture system having frames which may be manipulated and/or reoriented so as to assume various furniture configurations, for example, chair, love seat, sofa and bed, as well as desks and tables of various sizes and configurations.
- Furniture which may be converted between various configurations is highly desirable since one piece of furniture may serve several functions. Such “convertible furniture” is, in and of itself, notoriously well known as evidenced from the following list of patent publications: U.S. Pat. No. 3,008,782 to Osborne; U.S. Pat. No. 3,233,942 to Creutz; U.S. Pat. No. 3,672,719 to Haukedahl; U.S. Pat. No. 3,744,845 to Sooker; U.S. Pat. No. 4,277,856 to Danin; U.S. Pat. No. 4,506,927 to Lombardo; U.S. Pat. No. 6,135,545 to Liao; DE 3242148A1 to Gerhard; and WO 9104694A1 to Hollingsworth. Such convertible furniture is highly desirable since it is capable of accommodating the needs and/or desires of the user.
- Recently, in U.S. Pat. No. 5,722,716 to Thomas (the entire content of which is expressly incorporated hereinto by reference), there has been disclosed a novel furniture frame having components which may be manipulated and/or reoriented so that it assumes various furniture configurations. Specifically, the furniture frame according to the '716 patent includes a number of vertical and horizontal tubular sections which are joined to one another so as to form side frames which are separated latitudinally by at least one horizontally disposed cross-support member. A number (e.g., four) detachable L-shaped leg members may be inserted telescopically into the vertical or horizontal tubular components of the side frames and fixed in position, if desired, with the use of conventional pegs, screws, bolts, pins or like fixing elements.
- While such prior convertible furniture proposals serve their intended function of providing a single piece of furniture having multiple purposes, some improvement is still needed. For example, it would be highly desirable if a furniture frame could be provided so that any form of furniture may be constructed in dependence upon the user's desires simply by manipulating and/or reoriented one or more components of the frame without necessarily employing securing elements and which can be constructed of wood. It is towards fulfilling such a need that the present invention is directed.
- Broadly, the present invention is embodied in modular convertible furniture systems which include a pair of similar open-ended box frame assemblies which are nestable one within the other. A pair of slotted support rails are attached pivotally at respective opposing corners of one of the box frame assemblies so as to be movable between raised and lowered positions. When in a raised position, the rails provide a support for a solid board plank thereby becoming a seat back (e.g., for a chair, love seat, or sofa-type arrangement). When the rails are in a lowered position substantially parallel to the ground, the two box frame assemblies may be oriented back-to-back so as to provide a support for a mattress thereby converting the structure into a bed arrangement, for example. The box frame assemblies can be positioned on different sides and ends thereby allowing formation of tables and/or shelving as may be desired.
- These and other aspects and advantages will become more apparent after careful consideration is given to the following detailed description of the preferred exemplary embodiments thereof.
- Reference will hereinafter be made to the accompanying drawings, wherein like reference numerals throughout the various FIGURES denote like structural elements, and wherein;
-
FIG. 1 is a perspective view showing the modular convertible furniture system according to this invention in the configuration of a chair/sofa and table/shelf arrangement; -
FIG. 2 is perspective view showing the manner in which the box frames of the furniture system depicted inFIG. 1 may be reconfigured into a bed arrangement; -
FIG. 3 is a perspective view showing the convertible furniture system of the present invention as depicted inFIG. 1 , but reconfigured into a bed arrangement; -
FIG. 4 is a detailed enlarged perspective view showing a preferred manner by which the components of the convertible furniture system may be removeably coupled to one another to permit ease of reconfiguration; and -
FIG. 5 is a perspective view showing the convertible furniture system of the present invention depicted in one possible table configuration. - Accompanying
FIG. 1 depicts a particularly preferred embodiment of a modular convertiblefurniture frame system 10 in accordance with the present invention. As shown therein, thesystem 10 is comprised of primary and secondary open-ended box frame assemblies BF1 and BF2, respectively. Each of the box frame assemblies BF1 and BF2 are comprised of opposedlateral support frames - Planking boards 12-5, 14-5 span each of the opposed
lateral support frames lateral frames 12 is however slightly less than the dimension between the opposedlateral frames 14 so as to allow the former to be nested within the latter. - Preferably the difference in the dimensions between the opposed
lateral frames - As is perhaps best seen in
FIG. 2 , the box frame assembly BF1 includes a pair ofsupport rails 16 which may be pivoted about the bolted attachment point 16-1 between a raised position as shown inFIG. 2 to a lowered position as shown inFIG. 3 . The support rails may be maintained in their upright raised position as shown inFIG. 2 by means of bolted attachment point 16-2 which attaches a lower end of eachrail 16 to an adjacent lateral support board 12-2. - The inner surface of the
support rails 16 is provided with a recessed channel 16-3 which is configured to receive an L-shaped attachment bracket 18-1 associated with spanning planks 18 (seeFIG. 2 ). Thus, thespanning planks 18 may be positioned with respect to thesupport rails 16 by aligning their respective attachment brackets 18-1 with one or more channels 16-3 therein and then sliding theplanks 18 into position as shown to form a seat back structure. Although not shown in the drawing FIGURES, a similar removable structural arrangement as depicted for theplanks 18 may be provided for theseat plank 20. Alternatively, theseat plank 20 may be rigidly connected to the support boards 12-1 of thelateral support frames 12. The lowermost end of thesupport rails 16 is angled so as to determine the angular orientation as between theback planks 18 and theseat plank 20. Alternatively, of course, multiple holes to accommodate a bolt and nut arrangement may be provided in therail 16 and support board 12-2 so as to allow user selection of the desired angular orientation between theback planks 18 and theseat plank 20. - Upon removal of the bolt and nut arrangement from the bolted attachment point 16-2, the
support rails 16 may be pivoted about the attachment point 16-1 so as to assume their lowered positions as depicted inFIG. 3 . In this regard, it will be noted inFIG. 2 that each support rail has multiple holes 16-4 adapted to receive a bolt and nut arrangement when one of the holes 16-4 is aligned with a corresponding hole 14-6 associated with thelateral frames 14. Moreover, as noted previously, the dimension between the opposedlateral frames 12 is slightly less than the dimension between the opposedlateral frames 14. Most preferably, the difference in the dimensions between the opposedlateral frames support rails 16 so that when in their lowered position, they will each be closely adjacent to the support board 14-1 as shown inFIG. 4 . Thus, upon alignment with one of the holes 16-4 and the hole 14-6, a bolt and nut assembly (shown inFIG. 4 by way of example as a flathead bolt B and a blind nut N) may be positioned therein so as to secure therails 16 to thelateral box frame 14. Placement of anauxiliary spanning plank 22 thereby completes the reconfiguration of the box frame assemblies BF1 and BF2 into a bed arrangement as shown inFIG. 3 . - Those in the art will appreciate that the box frame assemblies BF1 and BF2 may be reconfigured to form a desk, shelving unit, table and the like as may be desired. For example, as shown in the accompanying drawing FIGURES, the
lateral box frames FIG. 1 ). The number of shelves may thus be preselected by the user for any given need. - Also, by way of example as shown in
FIG. 5 , the box frame assemblies BF1, BF2 may be stood on end so that their respective planking boards 12-5, 14-5 are disposed horizontally. Therefore, by connecting thesupport rails 16 to both the box frame assemblies BF1 and BF2 and placing aplanking board 18 thereon between the boards 12-5, 14-5, a table with a horizontal table top may be configured. Of course, the size of the table top may be changed by either omitting theplank board 18 or inserting one or moreother plank boards 18 as may be desired, in which case the relatively connection of therails 16 to each of the box frame assemblies BF1, BF2 would similarly change (i.e., so as to achieve the desired lengthwise dimension of the resulting table). - As can now be appreciated, the frames of the present invention provide a user with a number of furniture configuration options which are believed to not be possible with prior art convertible furniture frames. While only a representative number of possible furniture configurations has been shown in the accompanying drawing FIGURES and described above, those in this art may recognize that the component structures of the frames could be reoriented and/or reconfigured to achieve a number of other furniture configurations.
- While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
