TECHNICAL FIELDThe present invention relates to furniture, such as particular tables, which is shipped in compact form and erected or assembled by the consumer.
BACKGROUNDSince articles of furniture tend to be bulky and costly to ship, it is common to design and fabricate such items in knock down form. That is, the furniture is designed so that it is made up of sub-components, which when packed together, fit into a relatively compact shipping container. The consumer assembles the furniture at the point of use. And, preferably, the furniture is capable of being knocked down again for storage.
Numerous different designs and assembly concepts are known in the prior art. However, differences in execution of the design and manufacture can make a substantial difference to the consumer. Among the criteria that characterize a good piece of furniture are the following. The article must have a desired and pleasing esthetic appearance when assembled. The article must function for the desired purpose; typically, it must be strong and durable. The parts should fit together easily, and assembly should involve a minimum of tools and skill. Manufacturing should not demand extreme precision and cost should be low. The unassembled subcomponents should be sturdy and not prone to damage during rough shipment and handling. The carton into which the knock down table components are placed for shipment should be as compact as possible.
It is not easy to meet all the foregoing criteria. Furthermore, certain pieces of furniture have specialized requirements. For example, in tables used for computers, it is desirable to have a flat work surface, to hold the computer system components, particularly the monitor; and, to have at least one under-desk drawer, for holding a keyboard. That drawer ought to be closeable, to conceal the keyboard, when it is not in use. It is also desirable to provide at least one shelf for holding computer system components or related accessories, such as a printer or the tower which contains the processor. Sometimes the aforementioned parts of the computer system are heavy, and thus the table needs to be strong when assembled. Thus, while there has been a great variety of knockdown furniture in commerce, it has always been difficult to combine ease of assembly with strength and low cost.
SUMMARYAn object of the invention is to provide a table, preferably made of wood, which can be shipped in compact form, and then set up by a consumer with no tools, or minimal use of tools. An additional object is to meet the criteria which are mentioned in the Background; especially to provide a strong furniture article capable of bearing significant loads which can be shipped in a compact flat carton, and which after being erected and used, can be readily taken down again and made compact for storage. A further object is to provide a computer table, which meets the other objects, with shelves which can be extended from the side of the table for supporting computer components.
In accord with the invention, a table has a top, a back hinged from the top, and opposing side panels hinged from the back; and, thus the parts are compound foldable by virtue of the hinging. For compact shipment, the side panels fold inwardly onto the back, and the back then folds onto the underside of the top.
Thus the side panels are sandwiched between the top and back in the collapsed state. When the compound-hinged table of the invention is erected, the back is lifted up from the top as the top lies upside down on the floor. The end panels are rotated outwardly from the back, toward stops/stiffeners attached to the underside of the top. Means, such as a folding shelf or a stretcher or stops or the like, hold the panels in their erected position so they are perpendicular to the back, and so the panels support the front edge of the table top when it is turned upright for use.
Preferably, when the top of the table is wide, there is a stiffener running transverse to the length of the top, on the underside of the top. And, when the side panels are folded inwardly onto the back, the stiffener lies in a gap between the opposing free-swinging ends of the side panels.
In further accord with the invention, a table suitable for use with a computer system has at least one side panel which comprises one or more shelves, preferably both an upper shelf and a lower shelf. When the table is erected, the shelves pivot from parallelism with the side panel to a horizontal position. The upper shelf folds upwardly from its collapsed state position and is held in its use position by a support which also pivots upwardly from the side panel. In a preferred embodiment, the lower shelf pivots downwardly, either inwardly or outwardly from the side panel, according to what the user desires. In the collapsed state, suitable for shipment or storage, the shelves and the shelf support all lie parallel to the plane of the side panel; thus, the side panel is able to hinge into parallelism with the back of the table as described above. Optional drawers may be provided, for example for a keyboard.
A consumer can erect a table which is made in accord with the preferred embodiments of the invention quickly and easily without needing any tools. The table has very good strength and functionality. Yet, the table is economical to manufacture; and, fits in a compact package for shipment. The table does not demand that the consumer have patience and use tools, as is generally the case with prior art knock down furniture articles.
The foregoing and other objects, features and advantages of the invention will become more apparent from the following description of preferred embodiments and accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Parts of the present invention are described in provisional patent application Ser. No. 60/441,393 and co-pending application Ser. No. 10/607,104, filed Jun. 25, 2003. The disclosures thereof are hereby incorporated by reference. The various embodiments of the invention described below are preferably made of finished wood, with metal hinges. Other materials of construction may be used.
A table 20, having features which make it particularly suited for users of computers, is first described. The another table 20A, having side panels with fold-out shelves is described. Other products may employ the same essential features as in the tables. See the parent application.
For clarity of illustration some of the details shown in one Figure may not be shown in a corresponding Figure.
Referring now primarily to
As illustrated in
The back 50 has legs 53 which run parallel, in mating fashion, to the rear legs 51 of the side panels, where those panels are hinged connected to the back. Stretcher 30 which runs the full width of the back, between its two opposing end legs. The back is connected to the top by four hinges H5, so the back can fold onto the underside of the top.
The middle panel 26, to which is attached a hinged shelf 28, is a separate element. It slides into position, and is attached to the top by means of wedge fasteners, as described further below. When the middle panel is in position, centerline stretcher 32 runs between the center point of the lower end of the middle panel and a like place at the left side panel. Shelf 28 runs between the middle panel and the right leg panel. Shelf 28 is connected to middle panel 26 by hinge set H2, so it folds into position, to contact the right side panel 24R, as indicated by arrows in the various Figures.
Left drawer 34 and right drawer 36 are positioned underneath the table top 22. The drawers, shown upside down in
Hinges H5 connect the top to the back 50 in proximity to the rear edge. See
After the middle panel has been slid into place, the shelf 28 is folded down. See
Centerline stretcher 32 is then put in place, to connect the spaced apart bottom stretchers of the left side panel and middle panel. The arrows in
In use, downward extending legs of the table support the load. Table 20 has 8 legs in contact with the floor, namely, two legs at each side panel, two for the middle panel and two for the back panel. Since the rear legs of the back panel are closely adjacent to the rear legs of the side panel, as shown in
Front to back “parallelogramming” of the three panels is prevented by the glued construction of the parts, including the slats. The factory-made rigidity of the glued back parts, including the top and bottom stretchers, in combination with the fold down shelf 28 and centerline stretcher provide good resistance to left-right motion of the table. Other bracing for strength may be added, within the scope of the invention. Conversely, if less strength is required, some of the bracing, slats, etc, which have been described may be eliminated. (For simplicity of illustration, such kinds of features are omitted from
The table is easy to assemble for a user and requires no tools, except perhaps to install the knobs for the drawer fronts. The table components all fold flat and stow compactly in a shipping carton. There are no bolts or other fittings, so the possibility of such parts being insufficient in number is eliminated.
While the absence of bolts or screws is a feature, in other embodiments of the invention, conventional bolt or screw fasteners may be used, in substitution of the convenient wedges and other fasteners, which have been described or suggested. Still other fasteners known in the art may be used, and use of glue for permanent assembly may be contemplated.
Preferably, the hinges are common two-plate-with-pin hinges. It will be understood that the term hinges encompasses other configuration of connectors which enable the connected elements to move in the same manner as common hinges.
In a preferred embodiment, the top is about 48 inches long by 24 inches wide and about 31 inches from the floor. The middle panel is about 16 inches from the right side panel. While the table is described as a computer table, because that is its primary intended use, the article may be employed for other purposes. The drawers may be eliminated. Conversely, other features, such as other drawers and more shelves may be added. For example, a table may have two fold down shelves, one from each side of the middle panel. And, a table may have more than one middle panel. In another embodiment, less preferred, table 20 may comprise left and right side panels which hinge outwardly from the back when the table is in assembled condition, as illustrated by
During erection, the side panels fold out from a collapsed or shipment position, in which they are parallel to the back, as previously described for panels 24R and 24L. Table 20A does not have a center panel or stretcher holding the legs in place, although such might be added. Stop 175, a rail running front-back on the underside of top 22A, keeps side panel 24RR from swinging beyond its desired erected position at a 90 degree angle to the back. Second stop 179, a wood block having an integral pin which is frictionally engaged with a hole on the underside of the top, prevents the panel from swinging inwardly toward its collapsed state position. Other means including friction between the underside of the top and the panel may be used to hold the side panel in place. For instance, a spring plunger and detent, or pin or screw fastener, or a strut may be used. Optionally, there is a pull out drawer 34A, shown in phantom only in
With particular reference to
When it is rotated into erected position, as indicated by arrow B, upper shelf 155 is held in place by U-shape support 160. Support 160 rotates upwardly from its collapsed position indicated by phantom 160P, to its use- or working-position, as indicated by arrow A. It pivots about a horizontal plane axis running between pivot pins 171.
In its folded-in or collapsed position, indicated by phantom 160P, support 160 lies in a plane which is parallel to the plane of the side panel, and in a plane which is offset from the plane of the shelf 155 in its collapsed position. The front view of

Shelf 165 may have alternate configurations and alternate means for support. For instance, small round legs may substitute for the end plate; or a wood or metal piece may hinge downwardly from the free end of the shelf, to thus extend to the floor and act like plate 167. In still another embodiment, shown in
The lengths of the shelves 165, 155, which preferably lie within the same plane as may be conceived from
In the generality of the invention, when they are in their erected or working positions, the top, side panels and shelves may be only approximately horizontal or perpendicular, as applies. For instance, the top of the table may be somewhat sloped from back to front; and, the side panels may be somewhat angled relative to the back. Such inexact horizontal or perpendicular positions will are within the scope of the invention. A side panel may have both the upper shelf and the lower shelf, or only one, in the invention. Table 20A may have different overall dimensions from preferred table 20. In a preferred embodiment of table 20A, the height of the side panel is about 73 cm (29 inches); and, the width is about 35 cm (14 inches). Measured from pivot points, the cantilever length of the upper shelf is about 24 cm (13 inches); the cantilever length of the lower shelf is about 23 cm (9 inches); and the length of the support is about 26 cm (10 inch).
Although this invention has been shown and described with respect to one or more preferred embodiments, and by examples, those should not be considered as limiting the claims, since it will be understood by those skilled in this art that various changes in form and detail thereof may be made without departing from the spirit and scope of the claimed invention.
