DETAILED DESCRIPTION OF THE INVENTION

(8) In the embodiments disclosed herein, a dresser including a plurality of vertically spaced drawers is often used as an example of a piece of furniture in which an anti-tipping mechanism may be integrated or incorporated. The drawers often have the same width and are situated one on top of another. Their height and depth may vary. The anti-tipping mechanisms of the invention can be used on other types of furniture in addition to dressers and are not limited to use with only dressers. Also, the dressers may include one or more drawers in any of the sections therein.

(9) FIG. 1 shows a dresser 10 with drawers 12 each including a rearwardly-slanted front panel 14, and a frame 16 of the dresser 10 that includes an upper panel 18 and a lower panel 20. The entire front surface of the dresser 10, formed primarily by the front surface of the front panels 14 is thus rearwardly slanted, which means that its lower edge is more forward than its upper edge.

(10) Each drawer 12 does not have a rectangular shape. Rather, although the lower surface of each drawer 12, formed by a support panel, is horizontal and parallel to the floor or other surface below the dresser 10, the front panel and rear panel are rearwardly slanted. Each drawer 14 may also include opposite side panels that are also not rectangular in shape but rather with rearwardly slanted front and rear edges. The upper and lower edges of the side panels forming the drawers 14 are parallel to the floor or other surface below the dresser 10. Often, the lower surface of the dresser 10 will be parallel to the floor or other surface below the dresser 10, in which case, the lower panel and lower edges of the drawers 14 are parallel to the lower surface of the dresser 10.

(11) The design of the drawers 14 is relatively simple, and most likely these drawers 14 will be provided with conventional, currently known, tracks or comparable sliding mechanisms to enable their movement relative to the frame 12. Such tracks and drawer designs are examples only, for this embodiment as well as the other embodiments disclosed herein, and are generally not intended to limit the scope and spirit of the invention. Unless limited to such, the drawer designs and tracks used in furniture in accordance with the invention may vary as can be conceived by those skilled in the art to which this invention pertains to any number of different configurations.

(12) The rear facing surface 22 of the frame 16 of the dresser 10, behind the rear panels of the drawers 14, has a rearward slant and this surface may be one or more of the surfaces of each of two rear vertical supports on the opposed lateral sides of the frame 16 if present, a panel or board at the rear of the frame 16 that forms the rear of the dresser 10, and rear facing parts of side panels along the sides of the frame 16 of the dresser 10.

(13) FIG. 2 shows an embodiment of a dresser 24 wherein rectangular drawers 26 are provided. Each drawer 26 has a vertically oriented front panel 28, and preferably rectangular side panels 28, a flat, horizontal lower panel 30 and a vertically oriented rear panel 32. The drawers 26 are this rectangular when viewed from the side. Providing rectangular drawers is much more typical of furniture than the irregular parallelogram shaped drawers in FIG. 1.

(14) To enable tip-resistance with rectangular drawers 26 however, dresser 24 is constructed with its rear support to have a smaller height than the front support. That is, the distance D1 between the lowermost drawer and the back of the dresser 24 is less than the distance D2 between the lowermost drawer and the front of the dresser 24, when the lowermost one of the drawers 26 is fully inserted into the dresser 24. This height differential may be achieved by forming the side panels 34 with an angular slant at their bottom. The lowermost one of the drawers 26 will therefore be inserted in a downward direction into the dresser, not in a direction parallel to the horizontal plane, and an upward, angular removal of the lowermost drawer from the dresser 24. By contrast, in conventional dressers, the drawers are movable back and forth in directions parallel to the horizontal surface on which they rest.

(15) An important aspect of the dresser 24 is that the upper surface 36 of the dresser 24 is not slanted, but rather is parallel to the lower surface on which the dresser 24 rests. This is achieved in any number of ways. As shown, upper edges of the side panels 34 are constructed to be horizontal, i.e., with an angular slant at their top, and then a top panel 38 providing the upper surface 36 having a uniform thickness is situated on top of the side panels 34. As such, the distance D3 between the uppermost drawer and the front of the dresser 24 is less than the distance D4 between the uppermost drawer and the rear of the dresser 24, when the uppermost one of the drawers 26 is fully inserted into the dresser 24 and present entirely in the frame dresser 24. Front and rear edges 40, 42, respectively, of the top panel 38 are not perpendicular to the lower surface of the top panel 38 nor to top surfaces 44 of the side panels 34.

(16) In the alternative, it is possible to construct the dresser with a top panel that has a front edge portion having a smaller height than the rear edge portion. This top panel will not have a rectangular cross-section, with parallel top and bottom surfaces but instead they will be at an acute angle relative to one another. Regardless of the construction of the dresser 24, the distance D3 between the uppermost drawer and the front of the dresser 24 will less be than the distance D4 between the uppermost drawer and the rear of the dresser 24, when the uppermost one of the drawers 26 is fully inserted into the dresser 24 and present entirely in the frame of the dresser 24. This will result in the uppermost of the drawers 26 requiring a downward, angular insertion into the dresser, not an insertion in a direction parallel to the horizontal plane, and a corresponding upward, angular removal of the drawer from the dresser 24.

(17) Dresser 24 in FIG. 2 therefore differs from dresser 10 in FIG. 1 in that in dresser 10, the drawers 12 are movable in directions parallel to the horizontal plane on which the dresser 10 rests. However, to allow for this, the front panels of the dresser 10 must be slanted rearward toward their top and angled at an angle other than 90 degrees to the bottom panel of the drawer. By contrast, the front panels of the drawers 26 of dresser 24 are perpendicular to their bottom panel, but the drawers 26 do not move in directions parallel to the horizontal plane on which the dresser 10 rests. Rather, the drawers 26 move at an angle to this horizontal plane.

(18) FIG. 3 shows a dresser 46 similar to that shown in FIG. 2 except that the upper surface 48 of the top panel 50 is not horizontal, i.e., parallel to the horizontal plane formed by the support surface on which the dresser 46 rests, but rather is angled with a rearward slant. The angle A at which the upper surface 48 slants rearward may be the same angle of tilt or skew of the dresser 46. In this embodiment, the front and rear edges 52, 54, respectively, of the top panel 50 are perpendicular to the lower surface of the top panel 50 and to top surfaces 56 of side panels 58.

(19) FIG. 4 is an embodiment of a dresser 60 including a frame 62 and a plurality of drawers 64 that are movable into and at least partly out of the frame 62. The construction of the frame 62 is not intended to limit this embodiment of the invention. Indeed, the dresser 60 can have different frames with various numbers and shapes of drawers, possibly without legs or casters. Movement of the drawers 64 out of the frame 62 via tracks or other comparable sliding mechanisms enables access to the interior space thereof. By way of example only, the dresser 60 includes two front legs 66 and two rear legs 68. Legs 66, 68 are attached to or incorporated into the frame 62 and thus it will be considered that the dresser 60 comprises legs 66, 68.

(20) To provide tip-resistance, the rear legs 68 are shorter than the front legs 66. More generally, the lower surface of the rear legs 68 is spaced from a horizontal plane P, that is parallel to the horizontal plane HP defined by the surface on which the dresser 60 rests, a distance that is less than the distance between the lower surface of the front legs 66 and the same plane P. This distance may be as little as about 0.25 inches, but even such a small height differential causes the dresser 60 tilt rearward and aids in tip-resistance. A larger angle improves the tip-resistance, such a larger angle being obtained by increasing the distance-differential between the lower surface of the rear legs 68 to the plane P and the lower surface of the front legs 66 to the plane P. The greater the increase in the angle, the greater the resistance to tipping the dresser 60 forward. For example, by incorporating this ¼ differential in the legs 66, 68, it may be possible to alter a 50 pound weight that tips the straight dresser to become 52-55 pounds needed to tip it forward (the exact increase depends on mathematical calculations, e.g., the cosine of the angle). Further, visually it would not even be discernible that the dresser 60 is tipped backward, unless a round marble on its upper surface and it would roll backwards.

(21) If the legs are attached to the frame 62 in a common horizontal plane, which is possible but not required, then the rear legs 68 would be shorter than the front legs 66. It is conceivable that the front and rear legs 66, 68, respectively, are the same height but the rear legs 68 are attached to the frame 62 at a location above the location at which the front legs 66 are attached to the frame 62.

(22) If the dresser 60 is frameless, the longer legs would be attached to front edge portions of the dresser 60, e.g., one on each side, and shorter, rear legs would be attached to rear edge portions of the dresser 60, e.g., one on each side.

(23) As a result of the height differential between the front and rear legs 66, 68, the front bottom of the dresser 60 is naturally fractionally projected forward of the front top. As the dresser 60 tips further back by reducing the height of the rear legs 68, naturally the bottom projects forward as the top leans back. By its very nature, the bottom of the dresser 60 is angled forward, causing the top of the dresser 60 to be angled backward. One positive aspect of this construction of the dresser 60 is that there is an improved resistance to urge the dresser to tip forward.

(24) Upper surface 72 of the top panel 70 is not horizontal, i.e., parallel to the horizontal plane HP formed by the support surface on which the dresser 60 rests, but rather is angled with a rearward slant. Top panel 70 therefore may have a rectangular cross-section with parallel top and bottom surfaces, but this is not required. The angle at which the upper surface 72 slants rearward may be the same angle of tilt or skew of the dresser 60. In this embodiment, front and rear edges of the top panel 70 are perpendicular to the lower surface of the top panel 70 and to the top surfaces of the frame parts to which they are connected.

(25) The front and rear supports of dresser 60 are not adjustable, nor are any of the other supports or frames providing the rearward slant of dressers or other pieces of furniture in the invention. In the prior art, there are attachments to furniture that enable adjustment of the furniture relative to the horizontal surface on which the furniture is placed to accommodate uneven floors and the like. However, in the invention, the supports are not adjustable nor is there any possibility to adjust the height of the front or rear of the furniture in the invention. The supports are integrated into, incorporated into and built-in to the frame of the furniture or the furniture itself. No adjustability is possible. The furniture is sold in this manner.

(26) FIG. 5 shows an embodiment of a dresser 80 like dresser 10 shown in FIG. 1 except that it is mounted on casters or wheels 92 (although fixed legs, e.g., round-shaped legs, are also a possibility). Dresser 80 includes a frame 82 into which drawers 84 having interior spaces 86 are insertable and partly removable therefrom in directions parallel to the horizontal surface on which the dresser 80 rests. The dresser 80 also includes a top panel 88 and a bottom panel 90 to which the casters 92 are mounted. This embodiments provides anti-tip resistance by virtue of the rearward slant of the front and rear-facing surfaces of the dresser 80 (as discussed above with respect to dresser 10 in FIG. 1)

(27) FIG. 6 shows a variant of dresser 80, designated 80A, in which the casters 94 and 96 have different sizes, namely, the casters 94 at the front of the dresser 80A on each side, are larger than the casters 96 at the rear of the dresser 80A on each side. This height differential further increases the tip-resistance. Instead of casters 94, 96, support legs, e.g., round-shaped solid legs, or wheels, may be used. Generally, any structure that elevates the portion of the furniture to which the structure is attached may be used, whether a solid leg, a rolling wheel, or a rotatable caster.

(28) Thus, dresser 80A combines two aspects of embodiments of the invention, i.e., the construction of the dresser with a rearward slant and also with the lower, rear of the dresser being closed to the horizontal surface on which the dresser rests in comparison to the lower, front of the dresser. This latter aspect is provided by the different-height casters 94, 96.

(29) It is possible to provide the same size casters or legs, but just adjust their mounting location to the frame 82, i.e., mount the rear casters 96 to a more vertical location on the frame 82 than the casters 94.

(30) While these embodiments are directed to the serious, often fatal, accidents involving toddlers, they address all anti-tipping furniture issues that may arise, involving both toddlers and adults.

(31) While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
