Abstract

The utility model relates to a ribbed sponge, which comprises a sponge layer, and a torsion balance device is coated on the sponge layer. The utility model comprises multiple pairs of bearing plates, the bearing plates are connected with the piece of a torsion spring, and the piece of the torsion spring is supported on a support bottom plate. The bearing plates are bonded on the sponge layer which is coated, when people press on the sponge, the human body on the bearing plates exerts the external pressure for the bearing plates to cause the whole sponge to be deformed to enable the other part of the sponge to rebound when one part of the sponge is compressed to provide the dynamic balancing support force to provide uniform support for the human body.

As shown in Figure 1, reinforcement sponge 10 comprises sponge layer 27, and this sponge layer 27 is coated with a plurality of torsion balance devices 11 that are arranged side by side.As shown in Figure 2, torsion balance device 11 comprises many to bearing plate, and every pair of bearing plate comprises bearing plate 12 and following bearing plate 13.Above-mentioned bearing plate 12 is made by rigidity sheet material, and this sheet material can be plastics, sheet metal, fiberboard or plank.Bearing plate 12 links to each other with torque spring spare with 13 about in the of every pair, this spring part is made up of two V-shaped substantially long strip type torque springs 14 and 15, each torque spring comprises long-armed 16 and galianconism 17, as shown in Figure 3, the free end of galianconism 16 is provided with right-angle bending brachycephaly 18, this brachycephaly 18 is hinged with the back side of bearing plate, and long-armed 16 free end is provided with right-angle bending termination 19, and this termination 19 is connected with the parts 20 that wave shown in Figure 2.Shown in Fig. 4-6, wave the parts semicircular in shape, from wave portion's arc edge to above plat part have through

hole

22 and 23, this through

hole

22 and 23 is used to be connected the right-angle bending termination of torque spring 74 and 15.Waving parts 20 can directly be pressed against bearing plate (end illustrates) and go up and be not connected with it.Certainly waving parts also can be hinged with bearing plate, specifically be that cross through hole 21 is offered at the position therebetween, axial and the through

hole

22 and 23 of this through hole is axially perpendicular, it is just hinged with U-shaped support 24 by the cinclides and the above-mentioned through hole 21 that pass U-shaped support 24 to wave parts 20 like this, and above-mentioned U-shaped support is fixed on the bearing plate.Bearing plate 12 and 13 can be posted by on the sponge layer by adhesive up and down.

The schematic diagram that provides referring now to Fig. 8 is described the working condition of the torsion balance device that adopted in the utility model.In the ordinary course of things, bearing plate 12 and 13 is in the position that the diagram solid line is represented, yet when external pressure acts on down bearing plate 13, such as there being the human body that is pressed against bearing plate 13 to do the time spent, will make down bearing plate 13 move to the reaction torsion of the second place shown in the diagram dotted line with antagonistic spring 15.The above-mentioned displacement of bearing plate 13 down depends on the pressure size that acts on the bearing plate 13.In addition, the external pressure effect, also can make relative bearing plate 25 rotations of whole torsion balance device, consequently make bearing plate 12 move to dotted line position from the diagram solid line position, afterwards, last bearing plate 12 will outwards extrude on the corresponding site that is pressed on human body, and the pressurized zone of this human body also can produce the torsion of pressure with antagonistic spring to bearing plate 12 simultaneously.The whole torque spring device that acts on and react on external pressure in a manner described finally will tend to stable state, at this state, external action and reaction torsion will reach balance each other, bearing plate 12 can closely be pressed against on the human body with identical pressure with 13 up and down, thereby can provide comfortable even supporting to human body.

This field those of ordinary skill is understood that, thereby the torsion balance device applies the anti-power of work that reaction force can constantly be kept balance to the contacted human body Zone Full of this torsion balance device fast to the mobile meeting of human body, and coincide well with the body configuration.

As shown in Figure 9, torsion balance device in the reinforcement sponge of the present utility model also can longitudinally be arranged, be that following bearing plate 13 in one of them torsion balance device is adjacent with the last bearing plate 12 of adjacent torsion balance device, and the bearing plate up and down of two adjacent torsion balance devices all is posted by on the sponge layer 27.

Obviously, according to top instruction, can make various improvement and conversion to the utility model.Be appreciated that under the prerequisite of not leaving the utility model spirit, can realize the utility model by non-above-mentioned specifically described mode.Such as, torque spring spare can be the different shape shown in Figure 10-12.As shown in figure 10, can on torque spring 14 and 15, turn 35 be set so that bigger reaction torsion is provided.In addition, spring 14 and 15 free end crooked 90 ° forming the right-angle bending termination, and this termination can promptly be articulated in the sleeve 36 that is arranged at the bearing plate 12 and 13 back sides.

Torque spring spare also can be spring leaf, and this spring leaf free end can be fixed on the bearing plate, by stationary fixture 37 easily as shown in figure 11 like this.As shown in figure 12, torque spring spare can also be the torque spring of an integral body, and wherein the position has installed turn, fixes a circular discs again and just can form and wave parts 20 on turn.In addition, the torsion balance device of the setting in the sponge also can not be provided with bearing plate, as shown in figure 13, this bascule comprises the bigger flat spring of a pair of width 31 and 32, its c-shaped shape, they comprise free end 33 and stiff end 34, above-mentioned free end 33 constitutes the pressure-bearing surface that bears pressure, this pressure-bearing surface can bind against on the sponge layer, stiff end 34 is provided with two lugs 30 that bending is rectangular, and as shown in figure 14, this lug inserts and waves in the groove of offering in the parts 20 37, wave parts 20 and have the groove 37 that two above-mentioned lugs of confession insert in middle both sides, as shown in figure 15.In addition, another kind of form as the torsion balance device that does not need bearing plate can be referring to Figure 16, this device comprises independent template torque spring, its shape is c-shaped, its width is bigger, and two free end constitutes pressure-bearing surface, and the middle part of a side relative with pressure-bearing surface is formed with curved portions 39, this template torque spring can directly press or be hinged on the bearing plate by this curved portions, and above-mentioned pressure-bearing surface binds against on the sponge layer.

Reinforcement sponge of the present utility model can be widely used in the various human body support devices, as sofa, chair, Wheelchair, automobile chair, aircraft and wheel chair peculiar to vessel or the like.In addition, it also can make seat and back cushion separately, uses thereby can be placed on the ready-made human body support device.
