Japanese Patent Laid-Open No. 3-56730 JP 2002-39243 A

  The suspension arm (chassis receiving cushion arm) described in Patent Document 1 has a configuration in which a chassis load is applied between connecting ring portions provided at both ends of the suspension arm, and the unit configuration includes many members as described above. Since it is a complex structure, and it is a shape structure that is created individually for each unit, in all aspects such as parts management, assembly manufacturing, packaging storage, transportation and distribution, sales purchase, unpacking use, maintenance inspection, etc. In addition to the inherent and major problems of being cumbersome, inconvenient and cumbersome and extremely expensive in terms of price, including the unit structure to use many suspension arms in parallel The overall continuous configuration and the side-by-side configuration are extremely complicated, and the above problems are further increased.

  Further, since the suspension arm of Patent Document 1 has a structure in which a vertical external force is applied in the longitudinal direction of the longitudinally opposed leaf springs, it is an effective deflection restoring cushion material for a large deflection load such as vehicle body gravity. However, when many of them are used side by side, it has a vertical leaf spring structure that is unsuitable as a low load flexure restoration cushion material such as a bed flexure restoration cushion material, and the flexure restoration elasticity as a cushion material There is also an essential and big problem that the end user cannot change to the desired value.

  The wave coil spring described in Patent Document 2 is obtained by processing a large number of flat steel wires having a wave shape with different phases into a net-like shape and a cylindrical shape. In order to use them side by side, the overall connection configuration including the unit structure becomes extremely complicated. As a result, the wave coil spring disclosed in Patent Document 2 is similar to the suspension arm described in Patent Document 1. There are two essential and major problems.

  In the present invention, two flexible belt members are cross-coupled at predetermined intervals, and a large number of upper and lower ridge protrusions are connected in series in a chain, and the bending restoring cushion material resistant to external force, and many of them are connected in parallel. An object is to provide a large amount of a bed-restoring cushioning material.

  An object of the present invention described above is to form a plurality of round holes at a predetermined interval in the length direction of the flexible strip material in the central portion in the width direction of the two flexible strip materials having the bendability. Cut grooves that communicate with the holes and extend alternately in the opposite direction to the side edges of the flexible band material are formed in the respective flexible band materials, and the respective cut grooves are inserted into the round hole edge to each other, at every predetermined interval. By creating a cross-joint of crossed strip members, each flexible strip between the cross-joint portions is bent outwardly against each other against bending and restoring elasticity, and rolled up so that a large number of upper and lower ridges are almost linked. The ridge-belt band continuous body formed in series in the shape is configured.

  Next, while interposing the bending restricting rings of the ridge protrusions between the plurality of upper and lower protrusions in the continuous body, the support wires are respectively provided in the opposing holes of the rings and the round holes of the continuous body. In the supporting portion of the support wire rod provided for each desired area, the extension by the linearization restoration elasticity of the connecting body is prevented, and each ridge protrusion is individually retained for each desired area. In addition, the radial external force applied to each shape-retained ridge convex portion can be relaxed for each desired area by the bending recovery elasticity of each ridge convex portion and the deflection elasticity of the adjacent ridge convex portion, while each deflection limiting ring This can be achieved by making it possible to prevent over-deflection and crushing damage of each ridge protrusion due to an excessive external force locally applied to many ridge protrusions.

  However, in the state where a large number of the flexural restoration cushion materials connected in series are arranged in parallel and the ridges of the adjacent cushion materials are made to be in contact with each other, the support wire and the cross coupling portion are arranged in a parallel direction. It is good also as a bed-restored bed bending | restoration restoring | restoration cushion material which prevented the mutual separation to the parallel direction of each cushion material by bundling.

  According to each invention of Claim 1 and Claim 2 in this invention, interposing the bending restriction ring of each ridge convex part between each of the above-mentioned many vertical ridge convex parts in the above-mentioned ridge-and-belt band material continuous body, The supporting wire is inserted into the opposing hole of each ring and each of the round holes of the connecting body, and the supporting wire is extended by the linearization restoring elasticity of the connecting body at a locking portion provided for each desired area. In this way, the shape of each ridge protrusion is individually retained for each desired area, so that the radial external force applied to each of these shape retention ridge protrusions can be applied to the deflection recovery elasticity of each ridge protrusion and the adjacent ridge protrusion. There is an excellent effect that it can be relaxed for each desired area by the bending elasticity.

  On the other hand, when an excessive vertical external force (radial external force) is applied to the ridges, each inner surface of the ridges comes into contact with the outer surface of the deflection limiting ring, and the bending dimension of each ridge is increased. Since it can be strictly limited, even if the user accidentally steps on the ridges, there is also an effect that can surely prevent crushing damage of each ridge due to excessive external force that is locally applied to many ridges, Effective and safe to use as cushioning material for straight legs and long objects.

  In addition, according to each of the above inventions, a large number of upper and lower ridge protrusions in the ridge-and-belt band continuous body can be configured at once, and can be rounded and packaged as a whole, or can be used simply by extending the rounded one. In addition to its excellent effects of being easy to handle in all aspects such as assembly manufacturing, packing storage, transportation distribution, sales purchase, unpacking use, maintenance and inspection, it is advantageous in terms of price. It is possible to change the degree of wrinkle of the convex part and the bending recovery elasticity for each desired area according to the interval of the locking part provided for each desired area on the support wire, and the bending recovery elasticity as a cushioning material can be requested by the end user There is also an excellent effect that it can be easily changed accordingly.

  According to each invention of Claim 3 and Claim 4 in this invention, while the many of the said serially connected cushioning materials are approached and paralleled, the said ridge convex part in each adjacent cushioning material was made to mutually lean Since the support wire rod and the cross coupling portion are bundled in the parallel direction, the parallel cushioned flexure restoration cushion material that prevents the cushion materials from being separated in the parallel direction can be configured. When used as a restoring cushion material, there is an excellent effect that even an external force applied in a wide range in the bending direction by an extremely large number of ridges in the cushion material can be uniformly relaxed along a smooth bending envelope.

  Therefore, even if the sleeping person A turns over, the cushioning action can be quickly given to the sleeping person A, and the bending restriction rings are interposed between the plurality of upper and lower protrusions, so that the user can walk on the bed. Even if it jumps, the flexure dimensions of a large number of ridges can be strictly limited by each of the deflection limiting rings, so that the crushing damage of each ridge can be ensured by an excessive external force applied locally to the large number of ridges. It also has the effect of being able to stop.

  According to each invention of Claim 5 and Claim 6 in this invention, in addition to the said various effects, the cross-joint part of the said strip | belt material cross-joint body was couple | bonded with the eyelet coupler inserted in the round hole, and was reinforced. Therefore, the cross coupling portions can be reinforced without hindering the bending movement of the flexible band member, and the support wire can be easily inserted into the eyelet hole of the eyelet coupling tool, so that the workability is further improved and the cost is reduced. The effect that a bending restoration cushion material can be provided was added.

  As in the invention of claim 7 in the present invention, if the side shape of the deflection limiting ring is a flat elliptical shape, the deflection dimension of each ridge projection can be increased as much as possible, and the cushioning effect is improved, As in the eighth aspect of the invention, by forming the lateral width of the flexure limiting ring in the flexural restoration cushion material arranged in parallel to be slightly larger than the lateral width of the flexible belt material, contact between adjacent scissors convex portions Can be prevented, so that it is possible to prevent the rubbing noise between the ridges in the middle of the bending deformation, and to add an effect of being able to sleep comfortably and quietly. Further, as in the invention of claim 9, the sleeper A on the bed The longitudinal outer surface of the flat elliptical bending limiting ring interposed between the upper and lower ridges located at the head is brought into contact with the inner surface of the cross coupling portion, thereby laterally extending the upper and lower ridges located at the head. Because it can prevent direction stretching and numbness, go to bed Or moving the A and hips, not spread its influence to the head, the sleeping person A can continue to sleep.

  Furthermore, if the outer surface of the parallel-displacement flexural restoration cushion material is covered with a futon cover or the like as in the invention of claim 10, it is cool in the summer due to the heat insulating action of a large amount of air existing between the many ridges. The effect of becoming a warm bed flexion restoration cushion material could be added.

  As the best mode for carrying out the present invention, as shown in the lower diagram of FIG. 1, a series of flexure-restoring cushion materials are provided in series, in which a large number of substantially circular upper and lower vertical protrusions 7 are formed in series in a no-load state. First, as shown in FIG. 2, it has a slight rigidity and a large bending recovery property, such as a band made of a well-known stainless steel plate as shown in FIG. As shown in FIG. 2, two flexible strips 1 having a width of about 20-50 mm and a length of about 4 m are prepared as shown in FIG. 2, and each flexible strip has a diameter of about 2-4 mm at the center in the width direction. The round holes 2 are formed at predetermined intervals in the length direction of the flexible band material 1 by a well-known drilling process, and communicate with each of the round holes 2 and extend alternately in opposite directions to the side edges of the flexible band material 1. As shown in FIG. 2, each flexible band material is formed by manual work or press grooving. Form to.

  Thereafter, the flexible strips 1 are bent together by manual work or a robot arm in a state where the flexible strips 1 are combined as shown in FIG. The band material cross-bonded body 4 can be configured simply by inserting from the kerf opening end of the side edge to the round hole 2 and cross-connecting at the cross-connecting portion 4A at predetermined intervals as shown in FIG. In order to reinforce each coupling portion, the flexible band members 1 between the cross coupling portions 4A are bent outwardly as shown in FIG. The eyelet coupler 5 is inserted into the round hole 2 of the cross coupling portion 4A, and the cross coupling portion 4A is reinforced and coupled by manual crimping with a caulking tool a as shown in FIG.

  In the following, each of the above operations is sequentially repeated, and the flexible strips 1 are bent outwardly in a substantially circular ring shape against its flexural restoring elasticity, and a large number of upper and lower protrusions 7 having a radius of about 3 to 4 cm are formed. As shown in Fig. 4, the formed state is secured by manpower or a robot arm, and a tough and lightweight flame-retardant circular tube such as a bellows piping material for flame-retardant electric wire is flattened between these ridges. 5A and 5B, while the bending limiting ring 10 cut into the same width as each of the flexible band members 1 is interposed as shown in FIG. And a supporting wire 6 such as a thin and strong rope or a metal wire is inserted into the opposing hole 10A of the deflection limiting ring 10 as shown in FIG. As shown in FIG. 1, about 25 to 35 pieces of 7 were formed in series. It is to configure the 弯凸 strip connecting bodies 8 of about 2m.

  Next, a plurality of known wire rod locking means such as knots provided at the time of insertion of the wire rod 6 at both ends of the support wire rod 6 and the wire rod intermediate portion, and fastening latches attached to the wire rod intermediate portion after insertion of the wire rod 6 are used. 1A and 1B, the multiple connecting portions 4A are locked for each desired area, so that the connecting body 8 can be extended due to the bending and restoring elasticity of the hook projections 7. The large number of ridge protrusions 7 can be held at once for each desired area, and the radial external force applied to the ridge protrusion 7 for each desired area as shown in the above figures can be restored. A series connection according to the present invention having a length of about 2 m and a width of about 20 to 35 mm which can be relaxed for each desired area as shown in FIGS. It was possible to construct a flexible cushioning material.

  The flange diameter of the eyelet coupler 3 is as large as about twice as large as the diameter of the round hole, so that the flexible strip 1 can be easily bent in an annular shape between the kerfs 3, and the gap width of the kerfs 3 is further increased. Is easier to assemble if it is slightly wider than the plate thickness of the flexible strip 1, and the anti-spinning of the deflection limiting ring 10 with respect to the support wire 6 is formed with a narrow opposing hole 10A, and the support wire is formed in this hole. It is possible to prevent idling by inserting 6 tightly.

  Since the bending restoration cushion material by this invention became the above structures, the expansion | extension of the said convex-convex band material continuous body 8 by bending restoration elasticity, and expansion | extension for every desired area are each FIG. As shown in FIG. 6, since each of the round holes 2 and the supporting wire 6 inserted through the opposing hole 10 </ b> A of the deflection limiting ring 10 can be blocked by the locking portions 6 </ b> A provided for each desired area, When the shape can be retained for each desired area and a normal vertical external force (external force in the radial direction) is applied to the ridges 7 of the flexure restoration cushion material placed on the stationary base plate 9 as shown in the above figures, As shown in FIG. 6, the heel protrusion 7 is bent as shown in FIGS. 1 and 6 with a bending dimension within the mutual interval between the upper and lower inner surfaces of the ridge protrusion 7 and the outer surface of the bending limiting ring 10. The normal vertical external force can be relieved by the elasticity and the bending recovery elasticity of the adjacent saddle protrusion 7 That.

  On the other hand, when an excessive vertical external force (external force in the radial direction) is applied to the ridge protrusion 7 of the cushion material, each inner surface of the ridge protrusion 7 comes into contact with the outer surface of the deflection limiting ring 10, Since the bending dimension of the ridge protrusion 7 can be strictly limited, even if the user steps on the ridge protrusion 7 by mistake, the crushing damage of each ridge protrusion due to excessive external force can be surely prevented and It is effective as a cushioning material for legs and long objects, and can be used with peace of mind.

  However, since the above-described serially connected flexural restoration cushion material is elongated, it is effective as a cushion material for human legs and long objects. In order to configure the bed cushion material B by being arranged in parallel with each other, the support wire 6 intersects with the ridge protrusions 7 of the adjacent cushion materials in a state of being heeled together as shown in FIG. By binding the connecting portion 4A in a fixed manner at a predetermined interval with a known binding member such as a wire or a tough string, mutual separation of the cushion materials in the parallel direction and the serial direction can be prevented. As shown in the plan view of FIG. 7 having a lateral width of about 1 m and a length of about 2 m, a bed-like bending restoration cushion material B as shown in FIG.

  What are the overall expansion and the expansion for each desired area due to the flexural recovery elasticity of each of the ridges and strips connected to each other in parallel in the bed cushion material B arranged in parallel on the stationary base plate 9? Since the supporting wire 6 inserted into each round hole 2 can be blocked by the locking portion 6A provided for each desired area in the same manner as in FIG. 1 and FIG. 6 described above, a plurality of ridges having normal radial force applied thereto. 7, the saddle protrusion 7 to which a relatively large external force F1 is applied for each desired area due to each gravity, such as the head A1 and the waist A2 of the sleeping person A or the leg A3, as shown in the above figures. Against the elasticity of the sum of the flexure resilience and the flexure resiliency of the adjacent saddle protrusion 7, each of them is deformed into a flat shape as shown in FIGS. 1, 6, and 8. A moderate cushion action can be imparted to the head A1, the waist A2, the leg A3, and the like.

  However, as shown in FIGS. 1, 6, and 8, the longitudinal outer surface of the deflection limiting ring 10 interposed between the upper and lower protrusions located on the head of the sleeping person A is applied to the inner surface of the cross coupling portion 4 </ b> A. By touching, the expansion and contraction of the upper and lower ridges 7 located on the head can be prevented, and even if the sleeping person A moves his / her waist etc., the effect does not spread to the head, and the sleeping person A sleeps well. And forming the lateral width of the flexure limiting ring in the flexural restoration cushion material provided in parallel to be slightly larger than the lateral width of the flexible belt material by about 2 to 4 mm, thereby allowing contact between adjacent scissors projections 7 By preventing this, it is possible to prevent scratching noise between the ridges in the middle of the bending deformation, and to sleep more comfortably and quietly.

  On the other hand, since the external force F2 smaller than the external force F1 is applied to the heel convex portion 7 at the lower part of each inclined portion of the leg portion A3 or the head A1 and the waist portion A2 of the sleeper A, these heel convex portions 7 Is a vertical elliptical deformation dimension that is smaller than the deformation dimension of the heel protrusion 7 to which the external force F1 is applied, against the elasticity of the sum of the bending recovery elasticity and the bending recovery elasticity of the ridge protrusion 7 adjacent to the outside. As shown in FIGS. 6 and 8, it can be deformed in the vertical direction, and a pleasant cushioning action can be imparted to each of the inclined portions such as the head A1, waist A2, and leg A3 of the sleeping person A.

  Further, as shown in FIGS. 6 and 8, the intermediate saddle protrusion 7 to which the external forces F1 and F2 are not applied is the sum of the elasticity of the flexure restoration elasticity and the flexure restoration elasticity of the adjacent outer collar projection 7. Against the above, each of the three ridges 7 to which the external force is applied is bent in the vertical direction by the lateral pressing force by the lateral oval deformation force, and the outer ridges 7 are bent while being deformed into a vertical ellipse. Pushing sideways against the resilience, the outer ridges 7 with this force are greatly bent in the vertical direction and deformed into a vertically long ellipse as shown in FIGS. A large number of ridges 7 are bent along a generally smooth upper surface deflection envelope L as shown in FIGS. 1 and 6, so that the sleeping person A can be comfortably buffered and the sleeping person A can sleep well. .

  That is, the large number of ridges 7 in the bed cushion material B always bend and deform evenly along a smooth bending envelope even with external forces of different magnitudes applied in a wide range in the bending direction. Even if the person turns over, the smooth cushioning action can be quickly given to the sleeping person A and does not disturb the sleep.

  On the other hand, when an excessive vertical external force is applied to the ridge protrusion 7 of the cushion material, each inner surface of the ridge protrusion 7 comes into contact with the outer surface of the deflection limiting ring 10, and the deflection of each ridge protrusion 7. Because the size can be strictly limited, each heel is caused by excessive external force that is locally applied to many ridges even if the user steps on the ridge 7 by mistake or if the user walks or jumps on the bed. The crushing damage of a convex part can be prevented reliably.

  Note that the degree of ridge protrusion and the bending recovery elasticity of the ridge protrusion 7 can be changed according to the interval between the locking portions 6A provided for each desired area on the support wire 6, and the bending recovery as a whole of the bending recovery cushion material. The elasticity can be easily changed to a desired elasticity by the end user at the site of use, and if the outer surface of the bed bending restoration cushion material B as shown in FIG. Due to the heat insulation effect of a large amount of air, it is possible to provide a bed bending cushion material that is cool in summer and warm in winter.

  The bed flexure restoration cushion material B in the present invention can be used as it is laid under the mattress as it is, or can be used as a backrest of a chair, and on the upper surface of a very large number of ridges 7 in the cushion material B, If a hard thin mat or medium thickness mat is used, or a plurality of cushion materials B are stacked, the bed flexure restoration cushion material B according to the present invention is a multi-row series for laying a floor surface of a physical education facility. Naturally, it can also be used as a flexible cushioning material.
