The wire lattice can be secured to a perimeter frame using brackets which hook onto the lattice and also attach to the sides of the frame. The bed frame may include vertical supports or legs that can be quickly attached to the frame. Each leg may include an attachment plate and a catch extending above the attachment plate. The leg can be secured to the bed frame by sliding the attachment plate into a receiver attached to the bed frame. As the attachment plate is being inserted, the catch may engage a series of corrugations formed in the receiver. The catch may press against a corrugation to lock the leg into the receiver.Type: ApplicationFiled: July 31, 2018Publication date: February 6, 2020Inventors: Larry Self, Rolf Gunderson

Publication number: 20200040932Abstract: A quick action nut and a threaded fastener assembly including the quick action nut are proposed in the present invention. The quick action nut includes a nut housing, a control operating member, and at least two moving blocks movably connected inside the nut housing. A first through hole having a first hole axis is provided on the nut housing for a screw to pass through. Radial slide ways are provided on the nut housing for the moving blocks to move in a direction perpendicular to the first hole axis. The radial slide ways and the moving blocks have the same quantity, are matched in a one-to-one correspondence, and are distributed around the first hole axis. Threads are provided on the moving block to form or not form a threaded hole structure that is matched with the screw.Type: ApplicationFiled: July 31, 2019Publication date: February 6, 2020Applicant: Zhongshan Meitu Plastic.

Publication number: 20200040934Abstract: A strut and method for assembling a strut. The strut comprises two strut members attachable by a threading mechanism or the like. A first strut member is screwed into the second strut member. A pin hole is formed at the seam between the strut members and a pin is inserted into the pin hole. A locking ring is formed around the pin hole that includes an angular lip adjacent to the hole. The locking of the pin is accomplished, by swaging the angular lip into the hole and over the pin to lock the pin in the pin hole. The purpose of the pin is to ensure the joint does not untwist during operation.Type: ApplicationFiled: August 2, 2018Publication date: February 6, 2020Inventor: Michael S. Bell

Publication number: 20200040935Abstract: A deformable fastening system that has a deformable member and a mating member that seal together at a reduced clamp load from a conventional fastening system. The deformable member reduces the axial force that is required to install a fastener. The system can be used in connection with the installation of various fasteners with one or more steps under the head of the bolt, or a deformable washer with at least one step or at least one taper. The stepped configuration provides a reduced contact area where the stepped portion contacts the mating member which translates into reduced clamp force range for a given torque. Thus, less axial force is needed to properly install the fastener. Alternatively, a non-deformable bolt with a clinch feature and a stepped underhead forms a seal with deformed staking material when the bolt is staked in the staking material.Type: ApplicationFiled: July 2, 2019Publication date: February 6, 2020Inventors: Max Juengel, Jeramiah Slater
