Patio blocks and block systems with side surface positioning and retaining structures
A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.
Assembled floor unit
The invention relates to an assembled floor unit. The bottom plate of the assembled floor unit is rectangular and comprises a frame and a middle part; the frame is provided with a clamping hook and a clamping groove, the clamping hook is suitable for cooperating with the clamping groove to enable multiple blocks of bottom plates to connect and combine; the frame and the middle part are integrally formed; a plurality of through holes penetrating the thickness direction of the bottom plate are array-distributed in the middle part. The bottom plate has the advantages of material saving, easy manufacture, light weight, and the like. The assembled floor unit with the bottom plate can eliminate the process of embedding a filling layer into the bottom plate, and the light weight but high strength is beneficial to the transportation and export sales of the product.
Mechanical locking of floor panels
Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.
MECHANICAL LOCKING OF FLOOR PANELS WITH VERTICAL SNAP FOLDING
Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.
PATIO BLOCKS AND BLOCK SYSTEMS WITH SIDE SURFACE POSITIONING AND RETAINING STRUCTURES
A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.
IMPACT DAMPING MAT, EQUIPMENT ACCESSORY AND FLOORING SYSTEM
An impact damping mat comprises a plurality of layers arranged in a stacked formation. The stacked formation has a total thickness of no greater than 4 7/16 inches. The plurality of layers cooperate to provide the impact damping mat with at least one of a coefficient of restitution no greater than 30% and a selected sound reduction characteristic. The selected sound reduction characteristic can be a reduction of a maximum sound level of at least 5 dB from 40 to 63 Hz octave bands and at least 13 dB at and above 80 Hz octave bands normalized to a conventional inch rollout rubber flooring product.
ULTRASONICALLY WELDED MAT UNIT AND SYSTEM THEREOF
A mat unit includes a plurality of gaps defined by a first layer that are in open communication with gaps defined by a second layer so as to permit debris to fall entirely through both gaps to pass completely through the mat unit. The mat unit is part of an omnidirectional mat cleaning system that includes a first direction of travel above the mat unit extending through a door opening defined by a building structure. A different second direction of travel is above the mat unit extending through the door opening or another door opening defined by the building structure. The mat unit is installed on a floor adjacent the door opening. The mat unit cleans shoes regardless of the direction of travel traveled above the mat unit.
