[0002] With the development of the times, household electric beds as a new product have been gradually promoted in the market. As a bedroom furniture, people have higher and higher requirements for electric beds. Electric beds need to have beautiful appearance, soft texture and sufficient load-bearing performance. In order to achieve this requirement, electric beds are usually supported by a metal frame as a base, and a wooden board group with multiple sets of hinge joints and a lifting foot board is fixed on the base.

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0044] Figure 1 A schematic diagram of a bed structure according to an embodiment of the present invention (without a soft support layer) is shown. Figure 2 FIG. 1 is a schematic diagram of a bed structure according to an embodiment of the present invention (with a soft support layer). Figure 1 and Figure 2As shown, the bed structure provided by the present invention includes: a supporting mechanism 1, a flipping mechanism 2, a base 3 and a soft supporting layer 4; the flipping mechanism 2 is arranged between the supporting mechanism and the base 3, and the soft supporting layer 4 covers the top of the supporting mechanism 1; the supporting mechanism 1 includes at least two supporting components 5; in the flat state, each of the supporting components 5 is horizontally arranged in sequence on the top of the base 3; in the unfolded state, the flipping mechanism 2 causes at least one of the supporting components 5 to flip upward relative to the base.

[0045] The flip mechanism 2 can be set according to the number of support components 5 that need to be adjusted. Generally, 2 to 3 can meet the deformation needs of most supporting mechanisms 1. The specific number of support components is set according to needs.

[0046] The supporting mechanism 1 and the soft supporting layer 4 form a supporting surface, and use this to replace the traditional wooden supporting surface. The supporting component 5 can be made of a variety of materials and shapes of supporting parts, such as metal pipes, and the metal pipes are connected into a quadrilateral as the supporting component 5. It is best to use a regular quadrilateral to facilitate the reasonable arrangement of the internal space to control the volume of the whole bed. The most important thing is to completely abandon the bed board, and there is no need to cut, drill, install and other processes on the board, which eliminates the complicated intermediate processes, saves a lot of time and labor, reduces the production time of the whole bed by 30% to 40%, and greatly improves production efficiency.

[0047] Figure 3 FIG. 1 is a top view schematic diagram of a bed structure according to an embodiment of the present invention. Figure 3 The supporting mechanism 1 further comprises: a soft covering structure 101 ; the soft covering structure 101 covers the outer wall of the supporting component 5 .

[0048] The soft covering structure 101 wraps around the outer side of the support assembly 5, increasing the contact area between the soft covering structure 101 and the support assembly 5, and making the soft covering structure 101 more stable. When the bed is in use, the mattress is generally placed horizontally on the top surface of the support mechanism 1, and the top surface of the support mechanism 1 is completely covered by the mattress, but the side of the support mechanism 1 can still be touched and observed. Exposing the support directly to the outside is neither beautiful nor safe, especially when the user sits on the edge of the bed, the user's legs will contact the outer side of the support mechanism 1. Considering that the support mechanism 1 is mostly made of metal and various metal fixings, when it comes into contact with the human body, it may cause damage to the person.

[0049] The soft covering structure 101 can cover the whole or part of the supporting mechanism 1, and can be selected to cover only the outermost support surface of the supporting mechanism 1. The soft covering structure 101 can be made of EPE (pearl cotton), ethylene-vinyl acetate copolymer (EVA), sponge or hollow plastic profile. The shape of the inner cavity of the soft covering structure 101 fits the outer wall of the supporting member, and is fixed with an adhesive to form a whole, giving the outer side of the supporting mechanism 1 a soft and smooth contour, which is more beautiful and can also reduce the damage caused by direct collision between the user and the supporting mechanism 1. It overcomes the situation that the simple appearance cannot match the function of high-end products, resulting in the inability of high-end beds without wooden boards to form actual sales. The actual sales effect is very good and sales have been increased.

[0050] In addition, by adjusting the cross-sectional shape of the soft covering structure 101, various shapes can be formed to improve the aesthetics and comfort of the product and meet different customer needs. Figure 2 A schematic diagram of a bed structure according to an embodiment of the present invention (with a soft support layer) Figure 3 A schematic top view of a bed structure according to an embodiment of the present invention; Figure 4 is a partial enlarged schematic diagram of the card slot in an embodiment of the present invention, Figure 5 is a cross-sectional view of a support member covered by a flexible covering structure in an embodiment of the present invention, Figures 2 to 5 As shown, the supporting mechanism also includes: a slot 102 and a clamping piece 103; the slot 102 is arranged in the supporting mechanism 1, and the clamping piece 103 is detachably arranged inside the slot 102; the edge of the soft supporting layer 4 is connected to the clamping piece 103; the soft covering structure 101 is provided with a notch corresponding to the slot 102.

[0051] The soft support layer 4 can be made of non-woven fabric and a base fabric, which can be a pile fabric, 3D mesh fabric and other materials to increase the support strength; polyester cotton, flame retardant cotton: increase strength and play a flame retardant role; it can also add a waterproof coating or composite waterproof fabric; it can also be composited with sponge to increase softness. Non-woven fabric can also be replaced by ultrasonic cloth, or full fabric (without non-woven fabric) can be composited with other materials.

[0052] The card slot 102 is an opening provided on the support member where the clamping member 103 is to be installed and expands inwardly to form an open accommodation space, and the clamping member 103 is detachably fixed in the card slot 102, so as to conveniently and quickly fix the soft support layer 4. The card slot 102 and the clamping member 103 are provided to tighten the soft support layer 4 without increasing the volume of the supporting mechanism 1.

[0053] A soft covering structure 101 is wrapped on the support member, and a notch corresponding to the position of the slot 102 is left in the soft covering structure 101 to facilitate the installation of a clamping member 103; then a soft supporting layer 4 is used to cover the top surface of the supporting mechanism 1, and the edge of the soft supporting layer 4 hangs down from the edge of the supporting mechanism 1, and the outer side of the soft covering structure 101 is wrapped by the soft supporting layer 4. The support members at the edges of the supporting mechanism 1 can be open tubes with slots 102, and the clamping member 103 detachably fixes the soft supporting layer 4 in the slot 102 and tensions the soft supporting layer 4, so that the soft supporting layer 4 is flat and wrinkle-free, and the clamping member 103 cannot slide out of the opening of the open tube due to the pre-tightening force of the soft supporting layer 4. The production process is simplified, the aesthetics of the bed body is improved, and the supporting mechanism 1 is prevented from directly contacting the mattress and damaging the mattress; the tight soft supporting layer 4 tightly wraps the soft covering structure 101, which is both beautiful and helps prevent the soft covering structure 101 from deformation.

[0054] Figure 1 A schematic diagram of a bed structure according to an embodiment of the present invention (without a soft support layer) is shown. Figure 6 FIG. 1 is a partial enlarged structural diagram of a bed structure according to an embodiment of the present invention. Figure 1 and Figure 6 As shown, the top surface of the flexible covering structure 101 is flush with the top surface of the supporting component 5 .

[0055] The top surface of the soft covering structure 101 is flush with the top surface of the supporting assembly 5, that is, flush with the top surface of the supporting mechanism 1. At this time, the mattress is placed on the top surface of the supporting mechanism 1 without causing compression to the soft covering structure 101. At the same time, the soft covering structure 101 completely covers the side of the supporting mechanism 1 and is connected to the lower edge of the mattress, providing the user with a beautiful appearance and helping to maintain the preset shape of the soft covering structure 101.

[0056] Preferably, the top surface of the soft covering structure 101 is slightly higher than the top surface of the support assembly 5, about 0.2 cm to 0.5 cm. The soft covering structure 101 higher than the top surface of the support assembly 5 can be used as a buffer for the mattress and the support frame. The soft covering structure 101 made of flexible material will not be deformed by a slight squeeze, and can also reduce vibration, giving the user a better experience.

[0057] Furthermore, the support assembly 5 is composed of a plurality of support members, and the card slot 102 is arranged on the support member located at the edge of the supporting mechanism 1 .

[0058] When installing the soft support layer 4, the slot 102 is set on the support member at the edge of the supporting mechanism 1, which provides convenience for us to select a large piece of soft support layer 4 to cover the top surface of the supporting mechanism 1 as a whole. If a soft support layer 4 with an area larger than the top surface of the supporting mechanism 1 is selected, after the soft support layer 4 is covered on its top surface, the soft support layer 4 that exceeds the top surface of the supporting mechanism 1 is clamped into the slot 102 with the clamping member 103, which is convenient and quick, and after the whole soft support layer 4 is installed, even if no mattress is placed, it can provide a good appearance and improve the grade of the product.

[0059] Preferably, the slots 102 are arranged at the same level and form a complete closed loop, which ensures that the tension of the soft support layer 4 is uniform and more firm.

[0060] Figure 2 A bottom view schematic diagram of a bed structure according to an embodiment of the present invention; Figure 5 is a cross-sectional view of a support member covered by a flexible covering structure in an embodiment of the present invention, Figure 2 and Figure 5 As shown, the opening of the slot 102 faces the middle of the supporting assembly 5 .

[0061] The opening of the slot 102 can be at any position of the outer wall of the support member, and can meet the requirement of clamping the soft supporting layer 4, but it is best to set all the openings of the slot 102 on the inner side of the supporting component 5. When installing the soft supporting layer 4, it is necessary to wrap around the soft covering structure 101 for more than half a circle. The soft supporting layer 4 is wrapped around the outside of the soft covering structure 101 and is finally fixed in the slot 102 by the clamping member 103. The soft supporting layer 4 forms a 360-degree wrapping, which can further fix the soft covering structure 101 and the entire frame together, so that the soft covering structure 101 will not shake, which is beneficial to maintaining the shape of the soft covering structure 101 and maintaining the tension of the soft supporting layer 4.

[0062] Figure 5 is a cross-sectional view of a support member covered by a flexible covering structure in an embodiment of the present invention, Figure 5 As shown, the soft covering structure 101 has an outer inclined surface 1011 which is gradually inclined from top to bottom and inward, and an inner inclined surface 1012 which is gradually inclined from bottom to top and inward; the soft covering structure 101 covers the support member located at the edge of the supporting mechanism 1.

[0063] The soft supporting layer 4 extends downward from the opening of the card slot 102 to the bottom of the soft covering structure 101, and then extends upward along the contour of the soft covering structure 101 to form a semi-enclosure of the soft covering structure 101, and then reaches the top surface of the supporting mechanism 1. The soft supporting layer 4 relies on the inclined surface design at one end of the soft covering structure 101 to form a pre-tightening force on the soft supporting layer 4 to prevent the clamping piece 103 from being pulled out, and the clamping piece is clamped in the card slot only by the elastic force without loosening outward.

[0064] Figure 7 FIG. 1 is a schematic diagram of the detailed structure of a bed structure according to an embodiment of the present invention. Figure 7As shown, the supporting mechanism 1 includes: a first supporting assembly 6, a second supporting assembly 7, a third supporting assembly 8, a fourth supporting assembly 9 and a fifth supporting assembly 10; wherein, the first supporting assembly 6 and the second supporting assembly 7 are pivotally connected at the junction, and the third supporting assembly 8, the fourth supporting assembly 9 and the fifth supporting assembly 10 are pivotally connected at the junction; the first supporting assembly 6 includes: a first supporting member 601, a second supporting member 602, a third supporting member 603 and a fourth supporting member 604, the second supporting assembly 7 includes: a fifth supporting member 701, a sixth supporting member 702, a seventh supporting member 703 and an eighth supporting member 704, the third supporting assembly 8 includes: a ninth supporting member 801, a tenth supporting member 802, a 802, the eleventh support member 803 and the twelfth support member 804, the fourth support assembly 9 includes: the thirteenth support member 901, the fourteenth support member 902, the fifteenth support member 903 and the sixteenth support member 904, the fifth support assembly 10 includes: the seventeenth support member 1001, the eighteenth support member 1002, the nineteenth support member 1003 and the twentieth support member 1004; the first support member 601 and the second support member 602 which are parallel to each other are perpendicular to the third support member 603 and the fourth support member 604 which are parallel to each other, the first support member 601, the second support member 602 and the third support member 603 are fixedly connected, and the fourth support member 604 is overlapped with the first support member 6 01 and the top of the second support member 602; the fifth support member 701 and the sixth support member 702 which are parallel to each other are perpendicular to the seventh support member 703 and the eighth support member 704 which are parallel to each other, and the seventh support member 703 and the eighth support member 704 are overlapped on the top of the fifth support member 701 and the sixth support member 702; the ninth support member 801 and the tenth support member 802 which are parallel to each other are perpendicular to the eleventh support member 803 and the twelfth support member 804 which are parallel to each other, and the eleventh support member 803 and the twelfth support member 804 are overlapped on the top of the ninth support member 801 and the tenth support member 802; the thirteenth support member 90 1 and the fourteenth support member 902 are perpendicular to the fifteenth support member 903 and the sixteenth support member 904 which are parallel to each other, and the fifteenth support member 903 and the sixteenth support member 904 are overlapped on the top of the thirteenth support member 901 and the fourteenth support member 902; the seventeenth support member 1001 and the eighteenth support member 1002 which are parallel to each other are perpendicular to the nineteenth support member 1003 and the twentieth support member 1004 which are parallel to each other, the seventeenth support member 1001, the eighteenth support member 1002 and the twentieth support member 904 are fixedly connected, and the nineteenth support member 1003 is overlapped on the top of the seventeenth support member 1001 and the eighteenth support member 1002.

[0065] The support members are interconnected to form a rectangular support assembly 5, and a plurality of support assemblies 5 form a support mechanism 1. Each support assembly 5 is a support surface, and a plurality of support surfaces form a bed surface for placing a mattress. In daily life, the support surface of the bed is completely flat. Overlapping is to construct a certain height difference between the support members. The support members in the support assembly are not in the same plane, which is conducive to the attachment of the flexible coating structure 101 to the support members located at the edge of the support mechanism 1, increasing the support for the flexible coating structure 101, and the top surface of the flexible coating structure 101 forms the same plane as the top surface of the support assembly 5, that is, forming a complete support surface with the upper surface of the support mechanism 1 in a flat state. The support mechanism 1 can support more human body weight, prevent the flexible coating structure 101 from being flattened, and maintain the integrity of the appearance.

[0066] In addition, support members may be further added to each support assembly as a reinforcing rod and a base for installing equipment, such as adding a support member to the first support assembly to provide better support for the mattress, or as a base for installing a massager.

[0067] Figure 1 A schematic diagram of a bed structure according to an embodiment of the present invention (without a soft support layer) is shown. Figure 6 FIG. 1 is a partial enlarged structural diagram of a bed structure according to an embodiment of the present invention. Figure 1 , Figure 5 and Figure 6 As shown, the contact area 5001 where the supports overlap each other is located at a portion of the top surface area 5002 of the overlapping supports, and the other portion of the top surface area of ​​the overlapping supports is covered by the flexible covering structure 101, and the contact surface 5003 of the flexible covering structure is in contact with the end surface 5004 of the overlapping supports.

[0068] For example, the fourth support member 604 overlaps the first support member 601, and the contact area where the fourth support member 604 and the first support member 601 overlap each other is located at a part of the top surface area of ​​the overlapped first support member 601, and the other parts of the top surface area of ​​the first support member 601 are covered by the soft covering structure 101. The end surfaces of both ends of the overlapping fourth support member 604 are in contact with the contact surface of the soft covering structure, and the top surface of the fourth support member 604 is flush with the top surface of the soft covering structure 101, forming a seamless and flat bed surface. When the soft support layer is covered on the bed body, the bed body will not have other protruding parts, and the appearance is a smooth whole.

[0069] The soft covering structure 101 has a notch on it that just covers the overlapping ends, thereby increasing the longitudinal and lateral supporting force of the soft covering structure 101. When the weight of a human body is pressed on the soft covering structure 101 at the edge of the bed, the soft covering structure 101 can obtain better support and maintain its shape. This structure allows the edge of the bed to have a soft portion that makes the human body feel very comfortable, while also having a rigid portion that can effectively bear the weight.

[0070] In addition, during container transportation, beds are stacked up, and the bed at the bottom needs to bear a huge weight. Therefore, for traditional soft-padded wooden beds, the soft padded materials are often easily flattened. This structural design can effectively solve this problem, and all the weight is borne by the iron frame.

Figure 3 and Figure 8 As shown, the flip mechanism 2 includes: a driving device 201, a flip rod 202, a slide rail 203, and a pulley assembly 204; the driving device 201 is pivotally connected to the flip rod 202 and the base 3 respectively, and the horizontal direction of the thrust of the driving device 201 is the same as the horizontal direction of the flipping of the corresponding support assembly 5; the flip rod 202 is perpendicular to the horizontal direction of the flipping of the support assembly 5, and the pulley assemblies 204 are respectively provided at both ends of the flip rod 202; the slide rail 203 is arranged on the supporting mechanism 1, and the horizontal direction in which the slide rail 203 extends is parallel to the horizontal direction of the thrust of the driving device 201; the pulley assembly 204 can slide in the slide rail 203, and the pulley assembly 204 includes: a first pulley 2041, a second pulley 2042 and a support rod 2043; the first pulley 2041 and the support rod One end of 2043 is pivotally connected, the second pulley 2042 is pivotally connected to the middle part of the support rod 2043, and the other end of the support rod 2043 is pivotally connected to the base 3; the middle part of the support rod 2043 protrudes toward the support assembly 5 at an obtuse angle; when the supporting mechanism 1 is in the flat state, the second pulley 2042 is in contact with the slide rail 203 and can slide on the bottom surface of the slide rail 203; during the unfolding process of the supporting mechanism 1, the first pulley 2041 and the second pulley 2042 are both in contact with the slide rail 203 and can slide on the bottom surface of the slide rail 203; the flip rod 202 is vertically connected to the support rod 2043, and the connection point between the flip rod 202 and the support rod 2043 is located between the pivot connection between the support rod 2043 and the base 3 and the second pulley 2042.

[0072] One end of the paired sliding components is respectively pivotally connected to the base 3, and the support rod 2043 adopts a curved structure, that is, the middle part is at an obtuse angle, and the obtuse angle is preferably about 150 degrees. When the driving device 201 is working, it drives the flip rod 202 to rotate with the pivot connection between the pulley assembly 204 and the base 3 as the rotating axis, and the second pulley 2042 slides on the corresponding slide rail 203 to push the corresponding support assembly 5. When the support assembly 5 is flipped to 20 to 30 degrees relative to the base 3, the first pulley 2041 also contacts the bottom surface of the slide rail 203 and slides on its bottom surface. When there is only one pulley, there will be very large resistance when the support assembly is flipped 20 to 30 degrees. Adding another pulley can overcome this resistance and ensure that the support assembly 5 is flipped smoothly.

[0073] When the flipping mechanism 2 pushes the fourth support assembly 9, the fourth support assembly 9 flips upward with the pivot between the third support assembly 8 and the fourth support assembly 9 as the rotating axis, and the horizontal direction of the flipping is the same as the horizontal direction from the first pulley 2041 to the second pulley 2042; in addition, if the fourth support assembly 9 is provided with a fifth support assembly 10 in the horizontal direction from the second pulley 2042 to the first pulley 2041, and one end of the fifth support assembly 10 is connected to its pivot, then the pivot connection end of the fifth support assembly 10 and the fourth support assembly 9 will also follow the fourth support assembly 9 to flip relative to the base 3. At this time, only one flipping mechanism 2 can cause the two pivotally connected bed boards to flip and deform together; furthermore, a connecting rod 1005 can be added to the other end of the fifth support assembly 10, which is pivotally connected to the base 3 through the connecting rod 1005. When the fourth support assembly 9 flips to a certain angle, the other end of the fifth support assembly 10 will flip to a certain height with the connecting rod 1005 as the rotation radius. The length of the connecting rod 1005 is adjusted according to the specific structure of the bed. If it is too long or too short, the other end of the fifth support assembly 10 cannot be flipped and lifted, giving people a more comfortable posture. In this way, the flipping mechanism inside the bed can be reduced without affecting the flipping function of the support assembly, and the weight of the bed can be reduced, the volume of the bed can be reduced, and the production cost can be reduced.

[0074] Furthermore, the base 3 is fixedly provided with a load-bearing portion 301 ; when the supporting mechanism 1 is in the flat state, the load-bearing portion 301 is located directly below the support rod 2043 between the first pulley 2041 and the second pulley 2042 .

[0075] When the base 3 cannot provide support for the flipping mechanism 2, when the supporting mechanism 1 is laid flat, the flipping mechanism 2 will extend beyond the opposite side of the base 3 in space, increasing the volume of the bed. By setting the load-bearing part, the flipping mechanism 2 is confined to the space between the bottom surface of the base 3 and the bottom surface of the supporting mechanism 1, thereby reducing the volume, making transportation more convenient and more beautiful.

[0076] Fig. 9FIG. 1 is a schematic diagram of the lever arm of the flipping mechanism in an embodiment of the present invention. Fig. 9 As shown, the lengths and positions of the gravity arm, the first resistance arm and the second resistance arm of the flipping mechanism in the horizontal direction in the flat state are adjusted according to the following formulas (1) and (2) to reduce the length of the power arm of the flipping mechanism in the vertical direction in the flat state:

[0077] F1=(G×L3)÷L1 (1);

[0078] L2>(F1×L4)÷F (2);

[0079] Wherein, L1 represents the first resistance arm, L2 represents the power arm, L3 represents the gravity arm, L4 represents the second resistance arm, G represents the weight of the support assembly, F represents the thrust, and F1 represents the resistance;

[0080] Wherein, the first resistance arm is above the second resistance arm.

[0081] The resistance F1 is the force perpendicular to the base 3 starting from the contact point between the second pulley and the slide rail, the weight G is the gravity perpendicular to the midpoint of the slide rail contacted by the second pulley, the gravity arm L3 is the straight-line distance from the midpoint of the slide rail contacted by the second pulley to the rotation axis of the support assembly, the resistance arm L1 is the straight-line distance from the contact point between the second pulley and the slide rail to the rotation axis of the support assembly, and the power arm L2 is the straight-line distance from the pivot connection point between the support rod and the base 3 to the extension line of the thrust F.

[0082] The length of the power arm L2 is directly proportional to the thickness of the turnover mechanism, that is, the shorter the power arm L2 is, the thinner the turnover mechanism is, which in turn affects the thickness of the bed. For example, the length of the first resistance arm is increased and the length of the gravity arm is reduced to reduce the resistance. When the resistance is reduced, the length of the second resistance arm is reduced to further reduce the length of the power arm. When F<3000N and G>1285N, that is, when the bed bears the weight of the human body, through force analysis, simulate the change of the force arm position, calculate the change of force, find the best force arm, optimize the bed force arm structure, reduce the thickness of the bed, and make it thinner.

[0083] Furthermore, the width of the support component 5 covered by the flexible covering structure 101 is greater than its height.

[0084] The width of the support member is greater than its height, which can provide stronger vertical support for the flexible covering structure 101.

[0085] Figure 3 FIG. 1 is a top view schematic diagram of a bed structure according to an embodiment of the present invention. Figure 3As shown, further, the base 3 includes: a front frame 302 and a rear frame 303; wherein, the front frame 302 and the rear frame 303 are pivotally connected; the first support assembly 6 and the second support assembly 7 are rotatable relative to the third support assembly 8, the fourth support assembly 9 and the fifth support assembly 10 with the axis between the front frame 302 and the rear frame 303 as the axis.

[0086] The first support assembly 6 and the second support assembly 7 are arranged on the top of the front frame 302, and the third support assembly 8, the fourth support assembly 9 and the fifth support assembly 10 are arranged on the top of the rear frame 303. The edges of the second support assembly 7 and the third support assembly 8 closest to the rotation axis between the front and rear frames can be infinitely close to the rotation axis. The soft covering structure 101 is also separated at the junction of the front frame 302 and the rear frame 303 to cooperate with the pivot connection of the front frame 302 and the rear frame 303 for folding. The corresponding support assembly 5 can be folded following the front frame 302 and the rear frame 303 respectively. The eighth support member 704 and the eleventh support member 803 extend toward the base 3 respectively, and additional slots 102 are respectively provided in the extension sections and form two closed slots 102 circles with other slots 102, which are convenient and firm to install, ensure the flatness of the surface, and make it visually close to a complete plane; at this time, two soft support layers 4 can be selected for installation, and the two soft support layers 4 respectively cover the support components 5 on the top of the front and rear frames, and then use the clamping members 103 to clamp them into the corresponding slots 102 for tensioning, which reduces the requirements for the area of ​​a single soft support layer 4, and can be folded with the split soft covering structure 101 and the base 3, so that it can be directly assembled in the factory and then folded and transported to the destination, that is, the folding function is realized, which is convenient for transportation and saves costs; and the integrity of the soft support layer 4 and the aesthetics of the product are guaranteed.

[0087] Preferably, a stop bar may be added to the twentieth support member to prevent the mattress from shifting in the unfolded state.
