Referring now to
Storage assembly 11 can include a frame 13. Frame 13 can be shaped to include a bottom wall 21, a top wall 23, a first side wall 25, a second side wall 27, and a rear wall 29. Each of bottom wall 21, top wall 23, first side wall 25, second side wall 27, and rear wall 29 can consist of a single layer of material or can include a plurality of layers. As an example, each of walls 21, 23, 25, 27, and 29 can be made of one or more layers of cardboard, which cardboard optionally can be covered by a sheet of coated or uncoated paper or by a polymeric film; alternatively, as another example, each of walls 21, 23, 25, 27, and 29 can consist of or can include a material similar in strength and rigidity to cardboard. Suitable alternative materials can include, for example, plastics (for example, acrylonitrile butadiene styrene (ABS), polypropylene, glass-filled polyester, and glass-filled nylon), thin plywood, and thin metal. In other embodiments, the frame 13 or portions of the frame 13 can be injection-molded using materials, such as ABS, polypropylene, and acetal resins. Bottom wall 21, top wall 23, first side wall 25, second side wall 27, and rear wall 29 can together define a lower compartment 31. Lower compartment 31 can have a generally rectangular prismatic shape and can have an open front. Top wall 23, first side wall 25, second side wall 27, and rear wall 29 can together define an upper compartment 33, which can have an open top and an open front. Top wall 23, which defines the bottom of upper compartment 33, can serve as a shelf upon which one or more items to be stored can be seated. However, as can be seen, for example, in
Storage assembly 11 can also include a drawer 51. Drawer 51, which can be appropriately dimensioned for slidable movement within lower compartment 31 of frame 13, can be shaped to include a bottom wall 53, a front wall 55, a rear wall 57, a first side wall 59, and a second side wall 61. Each of walls 53, 55, 57, 59, and 61 can consist of a single layer of material or can include a plurality of layers. As an example, each of walls 53, 55, 57, 59, and 61 can be made of one or more layers of cardboard, which cardboard optionally can be covered by a sheet of coated or uncoated paper or by a polymeric film; alternatively, as another example, each of walls 53, 55, 57, 59, and 61 can consist of or can include a material similar in strength and rigidity to cardboard. Suitable alternative materials can include, for example, plastics (for example, acrylonitrile butadiene styrene (ABS), polypropylene, glass-filled polyester, and glass-filled nylon), thin plywood, and thin metal. In other embodiments, the drawer 51 or portions of the drawer 51 can be injection-molded using materials, such as ABS, polypropylene, and acetal resins. Bottom wall 53, front wall 55, rear wall 57, first side wall 59, and second side wall 61 can together define a compartment 65. Compartment 65 can have a generally rectangular prismatic shape and can have an open top.
Referring additionally to
Mount 121 can also include a first tab 141, a second tab 143, a third tab 145, and a fourth tab 147. First tab 141 and third tab 145 can be spaced apart from one another and can extend downwardly from rear edge 135 of spine 127, and second tab 143 and fourth tab 147 can be spaced apart from one another and can extend downwardly from front edge 133 of spine 127. First tab 141, which can be generally rectangular in shape, can be shaped to include a front surface 149, a rear surface 151, a first edge 153, a second edge 155, and a third edge 157. Alternatively, first tab 141 can have other shapes; for example, first tab 141 can be semi-circular, semi-elliptical, or triangular, or any other shape. First edge 153 can be flush with first end 137. Second edge 155 can be spaced inwardly from first edge 153. Third edge 157 can interconnect first edge 153 and second edge 155 at their respective distal ends from spine 127. First tab 141 can have a height h1 extending from the rear edge 135 of the spine 127 to the third edge 157 and can have a width w1 extending from the first edge 153 to the second edge 155. For illustrative purposes, height h1 can be, for example, 0.53 inch, and width w1 can be, for example, 0.81 inch. Second tab 143, which can be generally rectangular in shape, can be shaped to include a front surface 169, a rear surface 171, a first edge 173, a second edge 175, and a third edge 177. Alternatively, second tab 143 can have other shapes; for example, second tab 143 can be semi-circular, semi-elliptical, or triangular, or any other shape. First edge 173 can be flush with first end 137. Second edge 175 can be spaced inwardly from first edge 173. Third edge 177 can interconnect first edge 173 and second edge 175 at their respective distal ends from spine 127. Second tab 143 can have a height h2 extending from front edge 133 of spine 127 to third edge 177 and can have a width w2 extending from first edge 173 to second edge 175. Width w2 of second tab 143 can be approximately equal to or slightly less than width w1 of first tab 141. For illustrative purposes, height h2 can be, for example, 0.22 inch, and width w2 can be, for example, 0.75 inch.
First tab 141 can be oriented generally perpendicularly to spine 127, and second tab 143 can be oriented so that it angles slightly inwardly towards first tab 141 as second tab 143 moves downwardly from spine 127. Alternatively, second tab 143 can be oriented generally perpendicularly to spine 127, and first tab 141 can be oriented so that it angles slightly inwardly towards second tab 143 as first tab 141 moves downwardly from spine 127; alternatively, both first tab 141 and second tab 143 can be oriented so that they angle slightly inwardly towards each other as they move downwardly from spine 127. Tabs 141 and 143, together with the adjoining portion of spine 127, can be appropriately dimensioned to function as a first clip 144 that can be frictionally fitted over a top edge 179 of front wall 55 of drawer 51, as well as against adjacent portions of the front surface 181 and the rear surface 183, respectively, of front wall 55 of drawer 51. For illustrative purposes, where, for example, front wall 55 has a thickness t1 of approximately 0.19 inch, third edge 157 of first tab 141 and third edge 177 of second tab 143 can be separated by a space s1 of approximately 0.17 inch. The clamping force of such a clip can be maximized by having the height h2 of second tab 143 be approximately 0.3 to approximately 0.5 times the height h1 of first tab 141. First tab 141, in addition to being useful in helping to generate the aforementioned clamping force, can serve to orient handle 123 relative to the front wall 55 of the drawer 51 by generating torque counter to that provided by second tab 143.
Third tab 145 and fourth tab 147 can be sized, shaped and positioned correspondingly to first tab 141 and second tab 143, respectively, except that third tab 145 can have an edge 185 that can be flush with second end 139 of spine 127 (as opposed to being flush with first end 137 of spine 127) and can have other edges that are spaced inwardly from second end 139 of spine 127 and except that fourth tab 147 can have an edge 187 that can be flush with second end 139 of spine 127 (as opposed to being flush with first end 137 of spine 127) and can have other edges that are spaced inwardly from second end 139 of spine 127. Tabs 145 and 147, together with the adjoining portion of spine 127, can be appropriately dimensioned to function as a second clip 146 that can be frictionally fitted over the top edge 179 of front wall 55 of drawer 51, as well as against adjacent portions of the front surface 181 and the rear surface 183, respectively, of front wall 55 of drawer 51.
Handle 123, which can be positioned between second tab 143 and fourth tab 147, can include a first portion 191 and a second portion 193. First portion 191 can be generally flat and flush with spine 127 and can extend generally forwardly from front edge 133 of spine 127. Second portion 193 can extend from first portion 191 and can curve forwardly from first edge 133 of handle assembly 111 and downwardly to a depth d1 that is intermediate the depth d2 to which fourth tab 147 extends from first edge 133 of handle assembly 111 and the depth d3 to which third tab 145 extends from second edge 135 of handle assembly 111. For illustrative purposes, depth d1 can be, for example, 0.35 inch, depth d2 can be, for example, 0.19 inch, and depth d3 can be, for example, 0.5 inch. Second portion 193 can terminate in a rounded edge 195 that can have a radius of curvature of, for example, 0.31 inch. Handle 123 can be appropriately dimensioned to be grasped easily by a user, for example, using the thumb and the forefinger of one hand.
It should be understood that handle 123 is not limited to the shape described above and can be virtually any shape that permits manipulation by a user. Accordingly, handle 123 can be, for example, knob-shaped, loop-shaped, hook-shaped, rod-shaped, or any other functionally equivalent shape.
A notch 197 can be provided in spine 127 between handle 123 and second tab 143, and a notch 198 can be provided in spine 127 between handle 123 and fourth tab 147. Notches 197 and 198 can serve to minimize the distortion to spine 127 that can result from the forming of tabs 143 and 147 in the manner to be discussed below.
Ramp 125, which can be positioned between first tab 141 and third tab 145, can be appropriately constructed, dimensioned, and oriented to provide some weight-bearing support when placed under another object, such as top wall 23 of frame 13, as will be discussed further below. When viewed from above, ramp 125 can be generally semi-circular (as shown) or can have any of a number of alternate shapes, such as, but not limited to, semi-elliptical, triangular, rounded triangular, rectangular, rounded rectangular, or concave. In addition, when viewed from first end 137 or second end 139 of spine 127, ramp 125 can have a generally straight profile as it extends from rear edge 135 of spine 127 to a distal point 200 or can have a curved profile similar to that of handle 123. Moreover, ramp 125 can be generally flat across its width w3. Alternatively, as shown in
Ramp 125 can extend rearwardly from rear edge 135 of handle assembly 111 and downwardly from the top surface 129 of the spine 127 at an angle 0 that can range from approximately 20 degrees to approximately 70 degrees, or from approximately 30 degrees to approximately 60 degrees, or from approximately 40 degrees to approximately 50 degrees. In one embodiment, angle 0 can be approximately 45 degrees, and in another embodiment, angle 0 can be approximately 35 degrees. Ramp 125 can be shaped to include a ridge or embossment 201 that extends across the width w3 of ramp 125 proximate to rear edge 135 of spine 127. Ramp 125 can extend downwardly from rear edge 135 of handle assembly 111 to a depth d4 that is intermediate the depth d1 to which handle 123 extends downwardly from front edge 133 of handle assembly 111 and the depth d2 to which tab 147 extends downwardly from front edge 133 of handle assembly 111. Depth d4 is preferably greater than the depth to which top wall 23 of frame 13 can sag, which, in turn, can be a function of the width of compartment 31 (i.e., the spacing between first side wall 25 of frame 13 and second side wall 27 of frame 13) and the rigidity of the materials forming top wall 23 of frame 13. In this manner, ramp 125 can be inserted below top wall 23 of frame 13 so that top wall 23 of frame 13 can be raised by ramp 125 as drawer 51 is moved to a closed position. For illustrative purposes, depth d4 of ramp 125 can be, for example, 0.25 inch.
A notch 205 can be provided in spine 127 between ramp 125 and first tab 141, and a notch 207 can be provided in spine 127 between ramp 125 and third tab 145. Notches 205 and 207 can serve to minimize the distortion to spine 127 that can result from the forming of tabs 141 and 145 in the manner to be discussed below.
As will be discussed further below, handle assembly 111 can be formed as a one-piece structure. Materials suitable for use in making handle assembly 111 can include metals, metal alloys, polymers, polymer blends, and/or polymer alloys. Examples of suitable metals can include steel, copper, brass, and aluminum, and examples of suitable polymers can include ABS, polypropylene, and nylon.
