An apparatus for adapting sliding ceiling ladder racks for multi-use ladders is disclosed. An example embodiment includes creating an adapter bracket, which can be attached to the functioning members of a sliding ceiling ladder rack with the adapter creating a self-restraining ladder mount specifically designed to accommodate and interact with the weight, form, and structure of most common multi-positional/multi-use ladders. The apparatus for adapting sliding ceiling ladder racks for multi-use ladders generally includes a parabolic rung support assembly with an upper and lower end, with the lower end being purposely curved upward to operably engage and capture the rungs of multi-use ladder and the upper end consisting of an upper mounting plate, which is pivotally connected to the lower parabolic support by means of a tensioned hinge.

A storage unit which is substantially water proof is provided. The storage unit may comprise a shell having lower edges which mate into a groove formed in a top surface of a base to provide a substantially waterproof barrier therebetween. The junction between the lower edge of the side walls and the first groove may be sealed with a water proof sealant. A front side wall of the shell may have an aperture therethrough to allow users to move items into and out of the storage unit. A door may be attached to the storage unit to prevent water from entering into the storage unit through the aperture. Moreover, a lower edge of the door body may be inserted into a second groove formed in the top surface of the base to prevent water from entering into the storage unit from under the door.

A substrate installation unit for installing with other substrate installation units, in particular of the same type, for covering a substrate, wherein the substrate installation unit comprises a substrate-side attachment structure, which is designed for attaching to the substrate; and a plug connection structure, facing away from the substrate, for releasably plug connecting, in particular with a formation of a snap-in plug connection with a correspondingly designed plug connection structure of a surface installation unit, which comprises a utilization structure.

The technical disclosure of this Catwalk System Tiny House is the allowance of the user to walk in an erect manner alongside of the length, head or foot of the +mattress bed in a sleeping loft in a tiny house with a low ceiling and get onto the mattress bed laying on the loft floor, and get up from it without resorting to getting on one's hands and knees. This is new in the art of design of tiny houses with low ceiling sleeping lofts, as previously all lofts required the user to go from a ladder or stairway to a hands and knees crawling position to get to and from the sleeping mattress.

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the upper surface and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The mats also include first, second, third and fourth sides forming a perimeter of the mat, wherein the first and second sides include upper structures having a sloped lower surface and the third and fourth sides include lower structures having sloped upper surfaces. The sloped surfaces are configured to allow for overlapping with sloped surfaces other like mats for interlocking therewith while forming a generally flat continuous top and bottom surface of the overlapped mats. The mats may be interlocked by a fastening member which fits in aligned openings of the adjacent mats for connection therewith.

The invention relates 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 symmetrical parallel 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 an access ramp, and an assembly for driving said first end between a low position and a high position, said first end being supported by said drive assembly in both the low position and the high position. Said drive assembly comprises: a linear ram mounted under the plate (3), provided with a stationary end adjacent to said second end and rigidly connected to the bottom, and a mobile end, a carriage that is movable in horizontal translation and driven by said ram, said carriage resting on guides mounted on the bottom of the frame. Said carriage comprises two tappets, a pair of arms, the arms being symmetrical, each arm resting on one of the tappets of the carriage, each arm supporting the first end of the plate (3); in the retracted position of the actuator, the carriage is near said second end, the arms are in the low position and the first end is in the ramp position, and in the extended position of the actuator, the carriage is arm said first end, the arms are in the high position and the first end is in the high position.

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, anda 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.

A curved pathway including a double helix form with no center support column includes a plurality of segments, wherein each of the segments is formed from a plurality of rods coupled to a plurality of connecting nodes. The plurality of rods are arranged in a skewed tetrahedral geometry, which causes the plurality of stair segments to form a helical structure when the plurality of segments are coupled together. The plurality of rods form a spine on an underside of the plurality of stair segments. A pathway surface is coupled to each of the segments. In alternate embodiments, the curved pathway may be formed from sheet metal creased to form a plurality of linear support locations and connecting nodes.

A combination of elements to construct a threshold ramp construction includes tile elements each having a horizontal upper surface and ramp elements each having an upper surface including a sloped surface part and a horizontal surface part. The horizontal surface part adjoins the higher side of the sloped surface part. The tile elements and the ramp elements are configured to be arranged in superimposed layers to form the ramp construction, in which the superimposed layers include a lower layer and an upper layer, the upper layer supporting on the lower layer. In the ramp construction, the tile and/or ramp elements of the upper layer are arranged in a staggered position with respect to the tile and/or ramp elements of the lower layer.
