Definitions
- the invention herein pertains to tension members and particularly pertains to arcuate spring members for use in sofa beds .
- the aforesaid and other objectives are realized by providing uni-directional rigidifiers formed from arcuate tension members which extend longitudinally and have a U-shaped cross-section.
- the tension members In the upright position as a load is applied such as with an individual sitting on the folded mattress in the sofa mode, the tension members flex and the lateral slits open for seating comfort.
- the tension members When the mattress is unfolded in the usual bed mode the tension members are inverted and when a load is applied such as when an individual lays on the unfolded mattress, the lateral slits therealong close and therefore stiffen to prevent further flexing.
- the tension members provide the best support and comfort for both sofa seating and bed modes.
- the method of use described herein further demonstrates the benefits and advantages of the arcuate tension member.
- the tension member is formed with a plurality of lateral slits which allow flexing when pressure is applied to the tension member, such as while in the sofa mode.
- a sofa mattress can be fitted with a suitable number of tension members, such as by attachment to the spring assembly, or otherwise contained within the sofa bed mattress. Unfolding the mattress for use in the bed mode presents the tension members in an inverted configuration whereupon applying a load (pressure) to the mattress causes the slits to close, stiffening the mattress for the user.
- Fig. 1 shows the elongated, arcuate tension member of the invention in an upright, relaxed perspective view
- Fig. 2 pictures the tension member as seen in Fig. 1 in a right side elevational view depicting the elongated arc, the left side elevational view being a mirror image thereof;
- Fig. 3 depicts a right end view of the tension member as shown in Fig. 2, the left end view being a mirror image thereof;
- Fig. 4 demonstrates a top view of the tension member as shown in Fig. 2;
- Fig. 5 illustrates a bottom view of the tension member as shown in Fig. 4;
- Fig. 6 features a cross-sectional view of the tension member generally as along lines 6-6 of Fig. 4;
- Fig. 7 shows in schematic fashion the flexing of the tension member as shown in Fig. 2 when a load is applied;
- Fig. 8 illustrates the tension member in an inverted posture with the slits closed due to the applied load
- Fig. 9 depicts a schematic side elevational view of a typical foldable mattress of a sofa bed in the sofa mode with tension members positioned within the mattress;
- Fig. 10 demonstrates the foldable mattress of Fig. 9 in an extended or unfolded posture in the bed mode with the inverted tension members shown therein.
- Fig. 1 illustrates a perspective view of a preferred uni-directional rigidifiers presented as elongated tension members 10 having a plurality of lateral slits 11 spaced therealong.
- slits 11 are only slightly open when tension member 10 is in its relaxed, arcuate configuration. Openings 12 allow for screws, bolts, wires, springs, zip ties or other fasteners to be used to affix tension member 10 to the spring assembly inside mattress 21, cushion or the like as shown schematically in Figs. 9 and 10.
- Tension member 10 includes opposing lips 13, 13' which are relatively flat and act as top edges along the sides of U-groove 14 as seen in Figs. 3 and 6.
- Fig. 5 which portrays the bottom view of tension member 10
- open slits 11 are easily seen though tension member 10 is not under pressure such as by the weight of a user.
- slits 11 include apertures 11a on each end which are in communication therewith and provide pressure relief to tension member 10 as slits 11 close and open during use to prevent damage such as bending, creasing, stress fractures or the like to the surrounding edges.
- Preferred tension member 10 has a U-shaped cross-section as seen along lines 6-6 of Fig. 4 and is formed such as by a conventional stamping process from usual metal such as a thin coated steel.
- Tension member 10 is formed from twenty (20) gauge (0.8 mm thick) coated steel although other thicknesses and materials such as plastics, aluminum or composite materials if suitable may be employed.
- Tension member 10 was created to provide comfort to the user while extending the life of a mattress and as such must be formed from a durable material which will sustain its shape during repeated use over an extended time period.
- the preferred length of tension member 10 is preferably twenty-two inches (55.88 cm) with a width of one and a half inches (3.81 cm) although other lengths and widths may be used, depending on the particular application and specifications desired.
- a plurality of tension members 10 can be positioned for example in a foldable mattress of a sofa bed such as sofa bed 20.
- sofa bed 20 includes a standard foldable mattress 21 having at least lower or first section 22 and folded or second section 23.
- tension members 10 are in an upright position in folded or second section 23 which is shown folded atop lower or first section 22 which includes tension members 10 in an inverted position.
- Second section 23 in Fig. 9 is shown directly below seat cushion 24.
- first section 22 and second section 23 are positioned proximate the bottom of mattress 21 and are both inverted as shown larger in Fig. 8.
- tension members 10 stiffen due to slits 11 closing as seen in Fig. 8 thus stopping the flexion of tension members 10 to provide a firm support.
- mattress 21 As would be understood the upper portion of mattress 21 as is conventional allows for some deformation when a user lays thereon. However over time and extended, repeated use, the mattress and spring assembly (not shown) begin to flatten or sag and can provide an unstable, uncomfortable mattress for the user.
- tension members 10 By positioning tension members 10 within sofa mattress 21, an additional stiffening structure is provided to assist in supporting the spring assembly/mattress and will prevent sagging and "bottoming out” of the mattress as often occurs over time after repeated use.
- Tension members 10 provide support not only for the user but also for the mattress itself to maintain its posture and ultimately extend its "shelf life".
- one or more uni-directional rigidifiers shown as tension members 10 are formed such as by usual stamping from coated steel and installed in a suitable, conventional foldable mattress such as mattress 21 for use such as in sofa bed 20 as illustrated in Figs. 9 and 10.
- Foldable mattress 21 is positioned as normal in sofa bed 20 with usual removable back and seat cushions.
- tension member 10 in second (upper) mattress section 23 flexes (with slits 11 opening) to provide comfort to the user.
- Lower or first mattress section 22 having tension member 10 inverted will only slightly flex causing slits 11 to close preventing further flexing.
- tension members 10 are evenly spaced in an asymmetrical and parallel relation approximately five inches (12.7 cm) apart along the width of mattress 21 for a total of six (6) tension members 10 in both first and second sections 22, 23 respectively to provide additional stiffening support to mattress 21.
