Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
240 words
A portable ramp for placement adjacent a curb having a wall extending down to a street or the like for use with portable, wheeled devices for carrying goods comprising: (a) ramp means including: a support surface for supporting and enabling movement or the wheeled devices on the ramp, said support surface including a lower end for placement on the street; and said support surface further including an upper end for placement on the curb. said support surface also including a stop member extending downwardly therefrom adjacent said upper end, said stop member contacting the curb to prevent unwanted movement of the ramp as the wheeled devices are moved upwardly over the curb from said lower end to said upper end to enable goods to be carried; (b) two longitudinal side plates mounted with the support surface, each of said side plates including a load bearing section for placement on the curb; and (c) a pair of depending arms, one of each of which is mounted with said support surfaces adjacent one of each of said longitudinal side plates, said arm being mounted adjacent said upper end and extending downwardly to contact the wall of the curb wherein the angle between each of said depending arms contacting the wall of the curb and one of each of said load bearing sections of one of each of said side plates, respectively, is a load bearing angle to help support said wheeled devices.
Claim 2
Dependent Claim
240 words
A portable ramp for placement adjacent a curb having a wall extending down to a street or the like for use with portable, wheeled devices for carrying goods comprising: (a) ramp means including: a support surface for supporting and enabling movement or the wheeled devices on the ramp, said support surface including a lower end for placement on the street; and said support surface further including an upper end for placement on the curb. said support surface also including a stop member extending downwardly therefrom adjacent said upper end, said stop member contacting the curb to prevent unwanted movement of the ramp as the wheeled devices are moved upwardly over the curb from said lower end to said upper end to enable goods to be carried; (b) two longitudinal side plates mounted with the support surface, each of said side plates including a load bearing section for placement on the curb; and (c) a pair of depending arms, one of each of which is mounted with said support surfaces adjacent one of each of said longitudinal side plates, said arm being mounted adjacent said upper end and extending downwardly to contact the wall of the curb wherein the angle between each of said depending arms contacting the wall of the curb and one of each of said load bearing sections of one of each of said side plates, respectively, is a load bearing angle to help support said wheeled devices.
Claim 3
Dependent Claim
42 words
The ramp as set forth in claim 1, wherein the plate has an extended cut therethrough defining an integral stop member tab on the plate, the tab being bendable to position the stop member and define a handle opening in the plate.
Claim 4
Dependent Claim
28 words
The ramp as set forth in claims 1 or 2, wherein the lower end of the support surface is angled upwardly for generally horizontal engagement with the street.
Claim 5
Dependent Claim
24 words
The ramp as set forth in claim 1, wherein the upper end of the support surface is angled downwardly for engagement over the curb.
Claim 6
Independent Claim
68 words
A method of manufacturing a ramp for placement adjacent a curb or the like comprising the steps of: providing a support surface; cutting through said support surface to define a tab on the support surface; and bending the tab downwardly with respect to the support surface to abuttingly engage the wall of the curb when the ramp is adjacent the curb, thereby defining an opening through the plate.
Claim 7
Independent Claim
