Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
282 words
A U-shaped stand comprising a horizontal base and two side panels upstanding from two opposite margins of the base, each of said margins being depressed and having an upper surface spaced below the upper surface of the base to create an upright wall between the two surfaces, upwardly opening recesses formed through the two opposite end portions of each of said depressed margins, each of said recesses comprising a wide slot extending along said depressed margin and having one side edge coplanar with said wall, each of said recesses further comprising a narrow slot leading from one end of said wide slot and having side edges extending generally parallel to and spaced inwardly from the side edges of said wide slot, both of the narrow slots in each depressed margin leading in the same direction from the associated wide slots, a pair of webs of narrower width than said narrow slots and depending from and spaced along the bottom surface of each side panel, and a key on the lower end of each web, said keys being narrower than said wide slots and being wider than said narrow slots whereby each side panel may be assembled with and locked releasably to said base by moving the side panel endwise and downwardly to insert said keys into said wide slots and then by moving the side panel edgewise and horizontally to slide said webs into said narrow slots and lock said keys beneath the side edge portions of the narrow slots with the bottom surface of the side panel resting against the upper surface of said depressed margin and with the inboard bottom edge portion of the side panEl lying adjacent said wall.
Claim 2
Dependent Claim
282 words
A U-shaped stand comprising a horizontal base and two side panels upstanding from two opposite margins of the base, each of said margins being depressed and having an upper surface spaced below the upper surface of the base to create an upright wall between the two surfaces, upwardly opening recesses formed through the two opposite end portions of each of said depressed margins, each of said recesses comprising a wide slot extending along said depressed margin and having one side edge coplanar with said wall, each of said recesses further comprising a narrow slot leading from one end of said wide slot and having side edges extending generally parallel to and spaced inwardly from the side edges of said wide slot, both of the narrow slots in each depressed margin leading in the same direction from the associated wide slots, a pair of webs of narrower width than said narrow slots and depending from and spaced along the bottom surface of each side panel, and a key on the lower end of each web, said keys being narrower than said wide slots and being wider than said narrow slots whereby each side panel may be assembled with and locked releasably to said base by moving the side panel endwise and downwardly to insert said keys into said wide slots and then by moving the side panel edgewise and horizontally to slide said webs into said narrow slots and lock said keys beneath the side edge portions of the narrow slots with the bottom surface of the side panel resting against the upper surface of said depressed margin and with the inboard bottom edge portion of the side panEl lying adjacent said wall.
Claim 3
Dependent Claim
30 words
A U-shaped stand as defined in claim 1 in which the side edges of each narrow slot are centered with respect to the side edges of the associated wide slot.
Claim 4
Dependent Claim
29 words
A U-shaped stand as defined in claim 1 in which the inboard edge of each key is coplanar with the inboard bottom edge portion of the associated side panel.
Claim 5
Dependent Claim
96 words
A U-shaped stand as defined in claim 3 in which an inwardly opening groove is located on the inboard side of each web and between the upper surface of the associated key and the lower surface of said side panel, the horizontal depth of said groove from the bottom of the groove to the inboard side of said side panel being substantially equal to the horizontal distance between said wall and the inboard side edge of the associated narrow slot to enable the inboard bottom edge portion of the side panel to lie adjacent said wall.
Claim 6
Dependent Claim
78 words
A U-shaped stand as defined in claim 4 in which said webs and the closed ends of said narrow slots are located along said side panel and said depressed margins in such positions that the two upright end surfaces of each side panel are alined flush with the corresponding end surfaces of the base when the ends of said webs engage the closed ends of said narrow slots to stop edgewise and horizontal sliding of said side panel.
Claim 7
Dependent Claim
48 words
A U-shaped stand as defined in claim 1 in which the narrow slots in one side margin each lead in one direction from the associated wide slots while each of the narrow slots in the other side margin lead in the opposite direction from the associated wide slots.
Claim 8
Dependent Claim
40 words
A U-shaped stand as defined in claim 1 further including at least one rib located between the keyways in each margin and upstanding from the upper surface of such margin to engage the bottom surface of the respective side panel.
Claim 9
Dependent Claim
75 words
A U-shaped stand as defined in claim 7 in which the vertical dimension between the upper side of said rib and the lower surfaces of said narrow slots is greater than the vertical dimension between the upper surfaces of said keys and the bottom surface of said side panel to cause the latter surface to flex upwardly and force the upper surfaces of the keys into engagement with the bottom surfaces of the narrow slots.
Claim 10
Dependent Claim
231 words
A U-shaped stand comprising a horizontal base and two side panels upstanding from two opposite margins of the base, upwardly opening recesses formed in the two opposite end portions of each of said margins, each of said recesses comprising wide and narrow slots extending along said margin with the narrow slot leading from one end of the wide slot and having side edges spaced inwardly from the side edges of the wide slot, both of the narrow slots in each margin leading in the same direction from the associated wide slots, a pair of webs of narrower width than said narrow slots and depending from and spaced along the bottom surface of each side panel, a key on the lower end of each web, said keys being narrower than said wide slots and being wider than said narrow slots whereby each side panel may be assembled with and locked releasably to said base by moving the side panel endwise and downwardly to insert said keys into said wide slots and then by moving the side panel edgewise and horizontally to slide said webs into said narrow slots and lock said keys beneath the side edge portions of the narrow slots, and a plurality of ribs located between the recesses in each margin and upstanding from the upper surface of such margin to engage the bottom surface of the respective side panel.
Claim 11
Dependent Claim
231 words
A U-shaped stand comprising a horizontal base and two side panels upstanding from two opposite margins of the base, upwardly opening recesses formed in the two opposite end portions of each of said margins, each of said recesses comprising wide and narrow slots extending along said margin with the narrow slot leading from one end of the wide slot and having side edges spaced inwardly from the side edges of the wide slot, both of the narrow slots in each margin leading in the same direction from the associated wide slots, a pair of webs of narrower width than said narrow slots and depending from and spaced along the bottom surface of each side panel, a key on the lower end of each web, said keys being narrower than said wide slots and being wider than said narrow slots whereby each side panel may be assembled with and locked releasably to said base by moving the side panel endwise and downwardly to insert said keys into said wide slots and then by moving the side panel edgewise and horizontally to slide said webs into said narrow slots and lock said keys beneath the side edge portions of the narrow slots, and a plurality of ribs located between the recesses in each margin and upstanding from the upper surface of such margin to engage the bottom surface of the respective side panel.
