A ramp system is disclosed which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.

Hideaway pet ramps of the present disclosure are collapsible, discreet, and greatly facilitate access for pets onto beds, sofas, vehicles, and other elevated areas. This access can be greatly beneficial for infirm, geriatric, overweight, and small pets. Advantageously, pet ramps of the present disclosure also reduce the likelihood of injury for pet owners, such as injuries from lifting an animal onto the bed without the benefit of a ramp. Pet ramps of the present disclosure generally include a thin, rigid housing that discreetly fits underneath a mattress without compromising the comfort of the mattress. The housing forms a pocket configured to store a telescoping, height-adjustable and length-adjustable ramp assembly having an upper slide assembly and a lower slide assembly that may be deployed at any time a pet needs access to/from the bed.

A platform interface includes a platform, a hanger, and a ramping section. The platform defines a slot. The hanger has a body with a first end and a second end, a flange outwardly extending from the body and having a flange lip, and a gap extending between the first end and the flange lip. The ramping section has a hook configured to engage the flange such that the platform supports the ramping section via the flange. The gap is sized to prevent rotation of the hanger relative to the platform when the first end of the hanger is engaged with the slot and the hook engages the flange.

The disclosure includes a device and steps of a method for covering stairs from a first tread run to a last riser with a convertible ramp stair cover of a total variable length. The method includes extending a top end segment from a top joint of the convertible ramp stair cover a variable length to abut a top run of the staircase. The method additionally includes extending a bottom end segment from a bottom joint of the convertible ramp stair cover a variable length to abut the floor adjacent the staircase and changing an angle of the top segment with respect to the convertible ramp stair cover to match a surface of the top run of the staircase. The method yet includes changing an angle of the bottom segment with respect to the convertible ramp stair cover to approach a surface of the floor adjacent the staircase.

A foldable ramp system adjustable between a first position and a second position in which: in the first position, the foldable ramp system includes: a landing region substantially parallel to and elevated above a ground, where the landing region is mounted to a wall; and an inclined region extending from an end of the landing region toward the ground, where the inclined region is mounted to the wall; and in the second position, the landing region and the inclined region are folded against the wall.

A device for helping a wheeled vehicle pass over an obstacle. The device includes a stationary frame with a bottom and two symmetrical parallel side walls; a plate provided with two ends, a first end being movable between a high position and a low position, and an assembly for driving the first end between a low position and a high position. The drive assembly includes: a linear ram mounted under the plate with a stationary end adjacent to the second end and rigidly connected to the bottom, a mobile end, and a carriage movable in horizontal translation and resting on guides mounted on the bottom of the frame. The carriage includes two tappets and a pair of arms, the arms being symmetrical, each arm resting on one of the tappets of the carriage, and each arm supporting the first end of the plate.

A method is disclosed of attaching a tread assembly of a spiral staircase to a vertical support column. One step of the method involves providing a tread assembly having a tread portion attached to an arcuate mounting plate defining at least one hole through which extends a fastener defining external threads, the mounting plate having a first face defining a first radius of curvature. Another step involves providing a support column extending along an axis, the support column having a plurality of axially and angularly spaced apart tread attachment locations, each of the tread attachment locations having an arcuate outer surface defining a corresponding aperture for receipt of the fastener, the arcuate outer surface defining a second radius of curvature that is greater than the first radius of curvature. According to another step of the method, the tread assembly is loosely connected to one of the tread attachment locations of the support column. According to another step, the fastener is tightened such that the arcuate mounting plate of the tread assembly is elastically deformed to be in substantial engagement with the tread attachment location and applies tension to the elongate fastener to inhibit loosening thereof.

A ramp and/or platform assembly includes a decking system having a tread surface on at least a portion of a top deck surface of the decking system, wherein the tread surface includes a plurality of multi-tiered ridges on the top deck surface for contact with a traveling body on the top deck surface.

The present invention comprises a novel stair climbing device for self-moving robots that allows moving between dwelling levels using existing straight as well curved stairs. The straight ramp is attached to the stair's wall in a folded state and placed on the stair in the unfolded state. The curved ramp is stored in a folded state and is placed in the stair in unfolded state. When a vacuum robot comes close to the ramp, it can be unfolded automatically or manually and allows the robot to go up or downstairs to the next level of the dwelling. When the ramp is not in use, it can be folded into a stored state or/and be removed. The stairclimbing aide's dovetail ramp allows a robot to climb on the ramp due to its lower approach angle.

The invention relater to a device (1) for helping a wheeled vehicle pass over an obstacle, in particular for a person with impaired mobility. It comprises: a stationary frame (2) comprising a bottom and two side walls (9, 10), a plate (3) provided with two ends, a first end being movable between a high position and a low position in which said plate constitutes a first access ramp, an assembly for driving the vertical translational movement at least of said first end supported by said assembly, a flap (4) forming a front surface of the device in the high position of the plate and forming a second access ramp in the low position of the plate, the flap (4) being pivotably mounted on the plate at the first end of said plate, and a mechanism for deploying the flap (4), comprising at least one connecting rod including a front end hingedly connected to the flap (4), the hinge being separated from the upper edge and from the lower edge of said flap (4), a rear end linked to a first slide slidably mounted in a linear guide provided in the plate, and a central portion linked to a second slide (45) slidably mounted in a guide (19) provided in one side of the frame, the connecting rod moving in a substantially vertical plane.
