  Next, embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a bed. The bed 1 includes a base 2, a support 3 supported and received by the base 2, and a frame 4 supported by the support 3, as will be described later. A sheet-like body 5 stretched around the frame body 4 is provided. The bed 1 according to the present embodiment is a gatch bed that can be changed into a sleeping posture for sleeping and a back-up posture for helping a sleeping person to get up. The driving means is provided by a known means (for example, actual open flat 7) for causing the electric motor (not shown) to gatch the frame body 4 via a link mechanism (not shown). No. -31035 and Japanese Patent Laid-Open No. 9-56752) are employed as appropriate, and detailed description thereof is omitted.

  The base 2 is supported between a rectangular frame-shaped bone portion 2a and a piece of the bone portion 2a facing in the front-rear direction (hereinafter simply referred to as the front-rear direction) in the height direction of the person sleeping. A support receiving portion 2b for receiving the portion 3, a fence portion 2c protruding from the front and rear piece portions to prevent the sleeping person from falling, and casters 2d provided at the four corners of the bone portion 2a And is configured.

  The support portion 3 is elongated in the left-right direction (hereinafter, simply referred to as the left-right direction) with respect to the height direction of a person sleeping using a material having elasticity (for example, a metal such as iron, stainless steel, or titanium is preferable). The left and right plate-like support pieces 3a that are formed at the center in the left-right direction and are supported by the support receiving portion 2b, and extend from the support piece 3a in the left-right upward direction. The left and right handle portions 3b are substantially V-shaped, and the extending end portions of the handle portions 3b are fixed to left and right frame pieces 6 described later of the frame body 4 respectively.

  Reference numeral 9 denotes an interval adjusting device for adjusting the tension of the sheet-like body 5 by changing the interval between the left and right handle portions 3b, and the interval adjusting device 9 is capable of adjusting the height of the support piece 3a. Protruding portion 10 that protrudes toward the top side, and left and right links that are provided in a stretched manner between the protruding portion 10 and the left and right handle portions 3b and whose both ends are pivotally supported by the protruding portion 10 and the handle portion 3b. The link portion 11 can be expanded and contracted by appropriately changing the height of the protruding portion 10 and the link portion 11 between the left and right handle portions 3b. The projecting portion 10 of the present embodiment is configured to receive and screw a bolt 10a penetrating from the top side of the support piece 3a with a nut 10b from the floor side. It can be adjusted. The interval adjusting device 9 constitutes the adjusting means of the present invention, and the height of the protruding portion 10 can be adjusted by rotating the bolt 10a or the nut 10b with a driving device such as an electric motor (not shown). It is set as follows.

  Reference numeral 12 denotes a protective member for protecting the bolt 10a and the nut 10b protruding to the floor side of the support piece 3a. The protective member 12 is supported when the support portion 3 is supported and received by the support receiving portion 2b. The hole 2e is inserted into the hole 2e formed in the portion 2b. In order to prevent the hole 2e from being exposed in this inserted posture, the hole 2e is inserted between the support piece 3a and the protection member 12. A cover portion 13 for covering the cover is provided.

The frame 4 has a rectangular shape that is long in the front-rear direction and short in the left-right direction, and includes the front-rear frame piece 7 that opposes the front-rear direction and the left-right frame pieces 6 that oppose each other in the left-right direction. The left and right frame pieces 6 consist of a pair long in the front-rear direction and are provided so as to be movable in the left-right direction.
The left and right frame pieces 6 have a back piece 6a for receiving the back of the person who sleeps, a heel piece 6b for receiving the buttocks, a thigh piece 6c for receiving the thigh, and a lower knee piece 6d for receiving the lower part of the knee. A connecting portion that is formed by being divided into a plurality of parts in the front-rear direction, and that connects the adjacent pieces so as to follow each other's movement between the adjacent pieces of the pieces 6a, 6b, 6c, 6d. 8 is formed. Therefore, for example, when the user sits down on the collar piece 6b and enters the bed 1, the collar piece 6b receives not only the urging force of the support part 3 provided between the collar pieces 6b but also the adjacent back piece. By pulling the 6a and thigh pieces 6c, the repulsive force against the pulling of the support portion 3 between them can be received and the load is prevented from being applied only to a part. Incidentally, the connecting portion 8 of the present embodiment is a hinge, but it is of course not limited to the hinge. For example, the opposing ends of the adjacent pieces are butted together in a bowl shape, It is good also as a structure which equips both ends which faced | matched, and a structure provided with elastic members, such as rubber | gum, between adjacent pieces. Furthermore, as the connection part 8, it replaces with the said hinge, and shall be bent three-dimensionally, such as a ball joint and a universal joint, so that the pieces 6a, 6b, 6c and 6d can be connected with multiple degrees of freedom. it can.

  Further, between the left and right side pieces of the back piece 6a, the heel piece 6b, the thigh piece 6c, and the lower knee piece 6d, the support portion 3 provided with the distance adjusting device 9 is provided, so that the left and right frame pieces 6 are provided. The space can be expanded or reduced. Incidentally, the front and rear frame pieces 7 can be configured to be connected to the adjacent back frame piece 6a and the lower knee frame piece 6d, but in this case, to follow the expansion / contraction between the left and right frame pieces 6. Therefore, it is necessary to make the structure stretchable in the length direction. As a mechanism for expanding and contracting, a nested joint mechanism, a male-female fitting system, and the like are conceivable.

  The sheet-like body 5 is made of a material having air permeability and stretchability, and is formed by weaving, braided (including a net) or the like, but the sheet-like body 5 of the present embodiment. Is formed by braiding warp yarns 5a and weft yarns 5b. The warp yarns 5a are made of non-elastomeric polyester yarns with little stretchability, while the weft yarns 5b are made of elastomeric polyester yarns. Here, as the elastomeric polyester yarn, a yarn having a low rebound resilience is adopted. By forming such a sheet-like body 5, the sheet-like body 5 can expand and contract with a low rebound resilience in the weft direction. However, the warp direction has less stretchability. In the present embodiment, Diaflora (registered trademark, manufactured by Toyobo Co., Ltd.) is used as such a sheet-like body 5. Incidentally, the warp and weft may be an elastomeric polyester yarn, and the sheet-like body 5 may be stretched in a state in which these warp and weft are inclined.

  The sheet-like body 5 is stretched around the left and right frame pieces 6 so that the warp 5a is oriented in the front-rear direction and the weft 5b is oriented in the left-right direction so that the stretchability in the front-rear direction is small and the stretch is provided in the left-right direction. The At this time, the tension of the sheet-like body 5 due to the tensioning is applied to the support portion 3, but the spacing adjustment device 9 stretches and fixes the right and left handle portions 3 b to maintain the spacing between the left and right pieces 6. Appropriate tension can be given to the body 5. Moreover, the space | interval adjustment apparatus 9 can expand / contract the space | interval of the right and left handle part 3b, and can adjust the tension | tensile_strength of the sheet-like body 5 suitably.

  Further, since the support portion 3 has the handle portion 3b formed in the V shape, a space S is formed between the support portion 3 and the sheet-like body 5. As a result, the person sleeps and the sheet-like body 5 is bent. However, consideration is given so as not to contact the support part 3 and other members.

  When the bed 1 is gaited, the support portion 3 provided between the collar pieces 6b is fixed to the support receiving portion 2b, and the other support portions 3 can be separated from each other. By the way, the link mechanism for gating is attached to the support part 3 provided between the back piece 6a and the support part 3 between the thigh piece 6c or the lower knee piece 6d and raised up, It can be set as the structure which raises a knee.

  In the embodiment of the present invention configured as described above, the bed 1 has a sheet-like body 5 having air permeability and stretchability stretched around the frame body 4, but the opposite piece of the frame body 4 is held by both hands. Since the space S is formed between the sheet-like body 5 and the support portion 3, both the followability when gathering and the breathability when sleeping are satisfied. Although it is a thing, the bending which a person can sleep on the sheet-like body 5 can be permitted in the space S.

  Furthermore, the support part 3 is elastically deformed by the left and right handle parts 3b inward in the left-right direction under the load directed inward in the left-right direction, which works by tensioning the sheet-like body 5 on the left and right frame pieces 6. However, the urging force of the left and right handle portions is a load when a person sleeps on the sheet-like body 5 and a load when a person sits on one of the left and right frame pieces 6. Will also receive. In this case, the load when the person sleeps is received in a distributed manner by the extension of the sheet-like body 5 and the left and right handle portions 3b elastically deforming inward in the left-right direction. When sitting on one of the left and right frame pieces 6, elastic deformation in a state where the handle portion 3 b on the sitting side sinks outward in the left-right direction, and the sheet-like body 5 extends in the left-right direction by being pulled by this. And an elastic deformation in which the opposite handle portion 3b is lifted inward in the left-right direction via the elongated sheet-like body 5, so that the feeling of bottoming is relaxed and sitting. It will be comfortable.

  Moreover, the left and right frame pieces 6 are divided into a back piece 6a, a buttocks piece 6b, a thigh piece 6c, and a knee lower piece 6d in order to form a gatch bed. For example, when a large load is applied to one piece (the buttock piece 6b) such as when sitting on the buttock piece 6b, the adjacent pieces (back piece 6a, thigh) The piece 6c) is pulled and followed while being bent at the connecting portion 8, and as a result, the supporting portion 3 and the seat for supporting the following adjacent pieces (back piece 6a, thigh piece 6c). Since the elastic body 5 is elastically deformed and is received and dispersed, it can be avoided that the load concentrates on the sitting piece (the heel piece 6b) and sinks greatly.

  Further, the gap adjusting device 9 can adjust the tension of the sheet-like body 5 by adjusting the height of the protrusion 10 to expand and contract between the left and right frame pieces 6. As a result, the tension of the sheet-like body 5 can be easily adjusted in a tension state according to the weight of the sleeping person and the preference. In addition, in this case, since the distance adjusting device 9 can be stretched in each support portion 3, for example, the back piece 6 a makes the tension stronger and the collar piece 6 b weakens the tension. In addition, it can be done freely by the guidance of a doctor or caregiver who judges the user's situation (medical condition).

  Needless to say, the present invention is not limited to the above-described embodiment, and can be implemented, for example, in the second embodiment shown in FIG. In this configuration, the same reference numerals are assigned to the same components as those in the first embodiment, and the detailed description thereof is omitted.

  The bed 14 of the second embodiment is provided with a winding adjustment device 15 that can adjust the tension by winding up and unwinding the sheet-like body 5, and each piece 6a, 6b, 6c, The point which provided the two spaced-apart support part 3 in each 6d differs from the bed 1 of 1st embodiment.

  The winding adjusting device 15 constitutes the adjusting means of the present invention, and rotates the rotating shaft 15a to which the left and right ends of the sheet-like body 5 are attached by driving means such as an electric motor (not shown). In the present embodiment, it is attached to the back piece 6a and the lower knee piece 6d. For this reason, when the bed 14 is in the sleeping position, the tension is adjusted so that the bed 14 is slightly bent in consideration of the sleeping comfort. When it is in a back-up position, the seat-like body 5 at the back and below the knee is firmly stretched so that the upper body of the sleeper does not sink, and the tension of the part that pokes when getting out of the bed 14 can be strengthened. . Further, the winding adjusting device 15 of the present embodiment is attached as a pair to both of the opposing pieces of the frame body, and these can rotate in reverse to perform simultaneous winding (unwinding). ing.

  In addition, two supporting portions 3 are provided between the respective facing portions 6a, 6b, 6c, and 6d so as to be opposed to each other, and are necessary even if a load is applied to the end sides of the respective pieces 6a, 6b, 6c, and 6d. Since it can avoid leaning more than this, the frame 4 can be stabilized.

For example, the third embodiment shown in FIGS. 8 and 9 can also be implemented. The bed 16 of the present embodiment can automatically adjust the tension of the sheet-like body 5 in accordance with the weight of the sleeping person.
As the automatic adjustment, for example, a detection means 18 for detecting the weight of the user and a drive control means 17 for controlling the drive of the drive device for adjusting the height of the interval adjustment device 9 are used. The details are described below.

  The detection means 18 of the present embodiment is composed of a strain gauge and detects the weight as the strain of the handle portion 3b. However, the detection means 18 is set to the left and right of all the support portions 3 in order to accurately calculate the weight described later. Is provided in the handle portion 3b. The detection means 18 may be a load cell for detecting a load applied to the base 2 and detecting an error before and after the user gets on the load, or measuring a load applied to the support unit 3.

  The drive control unit 17 is a central processing unit (CPU) of a personal computer, and includes a calculation unit 17a for calculating the detection result of the detection unit 18, a storage unit 17b for storing various data, And a control unit 17c for adjusting the tension of the adjusting means.

  The calculating unit 17a can calculate the weight based on the strain amount detected by the detecting means 18.

  The storage unit 17b is, for example, a random access memory (RAM) that can store information in a readable and writable manner. The storage unit 17b is set data that sets a preferable tension strength of the sheet-like body 5 according to body weight, or is currently set. It is possible to store information such as the tension of the sheet-like body 5 (hereinafter simply referred to as “current setting data”). Incidentally, the storage unit 17b can be set so that the body pressure distribution can be performed by setting the setting data to an appropriate tension strength for each of the pieces 6a, 6b, 6c, 6d. Multiple settings data (for example, the back part is stretched strongly, the whole is stretched strongly, the buttock is stretched weakly, etc.) are stored in advance, and the setting data can be selected appropriately according to the preference of the person sleeping. Can do.

  The control unit 17c collates the weight data calculated by the calculation unit 17a with the setting data stored in the storage unit 17b to obtain the tension strength corresponding to the weight. A signal for adjustment is output to the driving device of the interval adjusting device 9.

20 is a weight input switch for inputting the appropriately created weight to the drive control means 17 and storing it in the storage unit 17b, and 21 is a fine adjustment switch for finely adjusting the sheet-like body 5, These consist of a keyboard, a CD drive, and the like. Incidentally, the fine adjustment switch 21 can be set as desired by outputting a command for appropriately adjusting each interval adjusting device 9 to the drive control means 17.
An example of the control procedure of the drive control means 17 of the present embodiment will be described based on the flowchart of FIG.

  First, it is determined whether or not a person has got on the bed 16 (step S1). However, if it is determined “NO”, that is, if a person is not on the bed 16, a determination of “YES” is made. Step 1 is repeatedly judged until Incidentally, whether or not a person has got on the bed 16 can be determined by whether or not the detection means 18 has reacted.

Next, when a determination of “YES” is made in step S1, the control unit 17c calculates the weight of the person on the bed 16 by the calculation unit 17a through the detection of the detection means 18. Is stored in the storage unit 17b (step S2).
Next, it is determined whether or not the weight is the same as the weight detected last time (the previous weight when the weight detected in step 2 is the current weight detected this time) (step 3). That is, when it is determined that the weight detected this time is the same as the weight detected last time, the control unit 17c outputs a signal based on the current setting data to adjust the tension (step 4), and the fine adjustment switch It is determined whether or not a fine adjustment command by 21 has been issued (step 5). On the other hand, if “NO”, that is, it is determined that the weight is different from the previously detected weight, the control unit 17c collates the weight obtained by the calculation with the setting data read from the storage unit 17b. After obtaining the tension strength corresponding to the weight, a signal for adjusting the sheet-like body 5 to the tension strength is output to the driving device of the interval adjusting device 9 to adjust the tension (step 6). The information on the adjusted tension strength is stored in the storage unit 17b as the current setting data (step 7), and then it is determined whether or not a command for fine adjustment is given in the step 5.
If it is determined in step 5 that “YES”, that is, a fine adjustment command has been issued, the tension is adjusted based on the command (step 8), but the tension of the finely adjusted sheet-like body 5 is adjusted. The information is stored by rewriting the current setting data in the storage unit 17b (step 7).

  On the other hand, if it is determined "NO" in step 7 and there is no fine adjustment command, it is subsequently determined whether or not the user has got off the bed (step 9). If the determination is “NO”, that is, it is determined that the user has not got off the bed 16, the process returns to step 5 to determine whether or not a fine adjustment command has been issued, and then “YES”, that is, until it is determined that the user has got off the bed 16. This process is repeated, but if “YES” is determined, the control unit 17 c outputs a command to loosen the tension of the sheet-like body 5 to the driving device, and sends it to the left and right frame pieces 6 and the support unit 3. (Step 10), and then the process returns to step 1 to determine whether or not a person has got on the bed 16. For this reason, the state where the tension is loosened continues until it reaches step 4 after it is determined in step 1 that a person has got on. The determination as to whether or not the user has got off the bed 16 can be made by detection of the detection means 18.

In the present embodiment, the weight of the user is detected and determined. However, the weight can be directly input by the weight input switch 20, and in this case, the control is performed without detection by the detection means 18. The collation of the part 17c can be performed.
In the present embodiment, the weight of the user 5 is detected and the tension of the sheet-like body 5 is automatically adjusted. However, the load applied to each of the pieces 6a, 6b, 6c, and 6d is detected. For example, when it is determined that the load is strong or weak depending on the result of detection, the tension is applied so that a uniform load is applied to each of the pieces 6a, 6b, 6c, 6d. Efficient body pressure dispersion can be achieved by adjusting.
Furthermore, although the case where the adjusting means is the interval adjusting device 9 has been described in the present embodiment, it is of course possible to adjust the tension by outputting a signal from the drive control means 17 to the winding adjusting device 15.

  By the way, for example, the frame body 4 in which the sheet-like body 5 is stretched is supported by the support portion 3 or the tension adjustment of the sheet-like body 5 is adopted for the bed 1 and the bed 16 of the first and second embodiments. The technology to do this can be applied to chairs and the like.

  Moreover, although the support part 3 of 1st, 2nd embodiment was set as the structure which elastically deforms the handle part 3b, as shown to FIG. 10, 11, the support part 23 is made into the support piece 23a and the right and left handle. The left and right handle portions 23b are pivotally supported by the shaft portion 24 so as to be swingable on the support piece 23a, and the left and right handle portions 23b are biased to be positioned at predetermined positions. By providing the elastic member, the left and right frame pieces 6 can be elastically supported by the support portion 23 even when the left and right handle portion 23b is inelastic.

The support portion 23 shown in FIG. 10 has a twist ammunition 25 corresponding to the elastic member wound around a shaft portion 24 and has one end fixed to the support piece 23a and the other end fixed to the left and right handle portion 23b. is there.
Further, the support portion 23 shown in FIG. 11A has a coil elastic machine 26 corresponding to the elastic member for urging the left and right handle portions 23b outward in the left and right directions between the left and right handle portions 23b. It is prepared.
Further, the support portion 23 shown in FIG. 11B includes a coil spring 27 corresponding to the elastic member for pulling the left and right handle portion 23b outward in the left and right direction, between the handle portion 23b and the bone portion 2a. It is prepared for.
