20100044152 | Blow Molded Plastic Interconnection Having a Receiving Section and a Locking Section - A blow-molded plastic female interconnection system has a receiving section and a locking section. The receiving section receives a male interconnect. The receiving section has a floor aperture shaped to allow the corresponding male interconnect be pushed into the locking section. The floor aperture can have various shapes depending on the shape of the male interconnect. Within the receiving section is a locking projection on the receiving section's back wall and the locking projection has a bottom section that defines a portion of the ceiling of the locking section which has no back wall. When the male interconnect is being pushed into the locking section, the locking projection deforms due to the locking sections no back wall. When the male interconnect is below the locking projection, the locking projection bottom section is positioned on the male interconnect to securely interconnect the male and female units. | 02-25-2010 |
20100044153 | A-Frame Ladder with a Flexible Gate/Barrier - An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a gate/barrier device to inhibit a person from using the first ladder's steps. The second ladder also has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the gate/barrier device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps. | 02-25-2010 |
20100044154 | A-Frame Ladder with a Tambour Gate/Barrier - An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a tambour device that inhibits a person from using the first ladder's steps. The second ladder has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the tambour device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps. | 02-25-2010 |

20080213041 | TRAFFIC BARRICADE HAVING INTERCHANGEABLE PARTS - The present invention is directed to traffic barricade having interchangeable base members and upright members that interconnect to each other. The base member and upright member are identical which allows the base member and the upright member to be interchanged together. | 09-04-2008 |
20080279624 | Secure interlocking system for plastic materials - A first plastic component and a second plastic component are joined together by an expansive joint system on the first plastic component and a driving joint system on the second plastic component. The expansive joint system has two expansive units while the driving joint system has corresponding driving units. When the driving units simultaneously expand the respective expansive units to a predetermined point, the expansive units contract to their original position and securely lock onto portions of the second plastic component. | 11-13-2008 |
20090001334 | CONTROL BARRIER - A barrier includes a housing having an interior surface and an opposing exterior surface extending between a first end and an opposing second end, the interior surface bounding a chamber that is adapted to receive a ballast. A coupler is rigidly connected to the first end of the housing, the housing and the coupler being separate discrete members that are connected together after formation. A structure, such as an opening or a post, is formed on the coupler for removably connecting a separate barrier to the coupler. | 01-01-2009 |
20090278103 | CONTROL BARRIER WITH ROTATABLE LEGS - A control barrier includes a barrier wall having a front face and an opposing back face each extending between a top end and an opposing bottom end, a first recess being formed on the front face at the bottom end of the barrier wall. A first slot extends through the barrier wall from the first recess to the back face. A first foot coupled with the barrier wall and being movable between a first position wherein the first foot is at least partially disposed within the recess of the barrier wall and a second position wherein the first foot is rotated a least 45° relative to the first position and is removably positioned within the slot extending through the barrier wall. | 11-12-2009 |
