Definitions
- This invention relates generally to the field of articulating bed frames and more particularly to a magnetically centered strap assembly for mattress retainer during articulation.
- Modem bedroom furniture is typically modular with features that are adjustable for comfort.
- Articulating bed frames provide various mattress supports which articulate relative to one another to provide angled support for the upper body, seat, thighs and lower legs. In the articulated position, a mattress which is firm enough for comfort may not maintain contact with the various articulating supports. It is therefore desirable to have a retainer system to maintain engagement of the mattress with the supports.
- the implementations disclosed herein provide a mattress retainer system having a tension assembly received in a sleeve on an underside of a mattress.
- the tension assembly incorporates an insertion flange and a strap is threaded through alternating slots in the insertion flange.
- the strap and insertion flange are received in the sleeve with the insertion flange providing resilient rigidity to thread the flexible strap into the sleeve.
- a magnetic engagement element mounted centered on the tension assembly and one or more magnets is embedded or attached to a support of an articulating system for a bed.
- a retainer system is configured to retain a mattress to an adjustment mechanism configured to move the mattress between a flat configuration and one or more inclined configurations.
- the retainer system includes a strap and an elongated stiffener.
- the strap is configured to extend through a sleeve on an underside of the mattress and having first and second ends that are releasably coupled to the adjustment mechanism proximate each left and right sides thereof.
- the elongated stiffener is coupled to the strap and configured to, when pushed through the sleeve, insert the strap through the sleeve.
- the retainer system may further include a magnetic component that is configured to be attracted by one or more magnets at a corresponding location of the adjustment mechanism.
- the elongated stiffener may have a substantially constant width over a majority of a length thereof, and the strap may have a width that is less than the substantially constant width of the elongated stiffener. Over a majority of a length of the elongated stiffener, the strap may be positioned between the mattress and the elongated stiffener when the retainer system is positioned in the sleeve.
- the elongated stiffener may include a plurality of slots through which the strap extends in an alternating manner.
- a bed system includes a mattress, an adjustment mechanism, and a retainer system.
- the mattress includes a sleeve on an underside thereof.
- the adjustment mechanism configured to move the mattress between a flat configuration and one or more inclined configurations.
- the retainer system extends through the sleeve and is coupled to the adjustment mechanism on each side of the sleeve to mechanically the mattress to the adjustment mechanism.
- the retainer system includes a strap and an elongated stiffener coupled to the strap.
- the strap may be positioned between the mattress and the elongated stiffener over a majority of a length of the elongated stiffener, the strap may be positioned between the mattress and the elongated stiffener over a majority of a length of the elongated stiffener, the elongated stiffener may include a plurality of slots through which the strap extends in an alternating manner, and/or the retainer system may be magnetically coupled to the adjustment mechanism.
- a method for retaining a mattress to an adjustable mechanism that moves the mattress between a flat configuration and one or more inclined configurations.
- the method includes: providing a mattress having an underside with a sleeve extending across a majority of a width thereof, providing a retainer system having a strap and an elongated stiffener, providing an adjustment mechanism, inserting the retainer system in the sleeve by pushing the elongated stiffener through the sleeve to pull the strap through the sleeve, positioning the mattress on the adjustment mechanism, and coupling first and second ends of the strap to left and right sides of the adjustment mechanism after inserting the retainer system in the sleeve.
- the retainer system may include a magnetic component attached to the elongated stiffener, and the adjustment mechanism may include a magnet.
- the method may further include positioning the mattress on the adjustment mechanism for the magnetic component of the of the retaining assembly to magnetically couple to the magnet of the adjustment mechanism, and may further include performing the coupling of the first and second ends of the strap to the left and right sides of the adjustment mechanism while the magnetic component of the retaining assembly is coupled to the magnet of the adjustment mechanism.
