Abstract

The present invention relates to a stretcher that can be set at a stretcher configuration or a wheelchair configuration, while increasing the rigidity of the frame structure, so that a patient is easy to maintain a posture while increasing the safety. The configuration of the stretcher can be changed in one operation. The stretcher comprises: an above-knee portion (4) as a seat for supporting the thigh part of a patient; a waist portion (3) contained in a backrest that can support the upper body; an armrest portion (6) as an armrest; and a below-knee portion (5) that can support the lower body. The above-knee portion (4), the waist portion (3), the armrest portion (6), and the below-knee portion (5) can be assembled into a stretcher configuration where the mat face including the armrest is planar, or a wheelchair configuration where the mat is bent. Either one of the two configurations can be used to carry a patient.

Description

V. Description of the invention (l); The present invention relates to a stretcher that can also be used as a wheelchair. To explain in more detail, "The present invention relates to a frame connection structure that can be changed to a wheelchair stretcher. In order to support the patient's pedestal or back mechanism, the handle is moved by hand. Improvement of supporting structure of device and safety handrail. , In response to a stretcher that requires a caregiver or patient who has difficulty getting up or moving, which is called a “patient ^” in this list, f is a stretcher that lifts up the back ’or borrows It can be deformed into a wheelchair stretcher by bending the foot part downwards while lifting the back part (Japanese Patent Application Publication No. Hei 10-52459). According to such a stretcher, the patient is lying down After moving the patient from the bed to the stretcher, it is possible to change the shape to a chair, and it is possible for the patient to move it in the posture of the seater. However, such a stretcher has various problems as disclosed below. Point. L. The first problem is the connection structure of the frame. That is, the frame of the conventional f-tank is the equivalent of the waist by the rotation of most pipes connected by bolts or the like. Or the knee part is combined to be able to test. For example, at the waist of the frame, the pipe on the right side of the upper body = the pipe on the side of the half body, the pipe on the left side of the upper body, and the pipe 2 on the left side of the lower body are connected by screw inspection for free rotation. . In this way, the left and right two are connected to each other to rotate freely, and in terms of the frame that is formed, the frame :: twisting occurs and becomes insufficiently flexible ... because the frame is directly punched with bolts and penetrated, so it will be caused by Places that have been enlarged and bent due to long-term use may become unstable and deteriorate in durability.

2009-3469-??. Pus Page 5 of 5 Description of the invention (2) In addition, in order to change the convenience of the burden, it will be necessary to be able to handle when moving. It is the stability of the second person with sufficient strength to maintain the posture to maintain the posture, so that the body part can be taken comfortably without losing and stabilized as a wheelchair. The third concern is that the pad becomes flat. The lowered position makes it necessary to hold the wheelchair in a necessary position to prevent the wheelchair from being locked. Furthermore, it is possible to support the patient-root relationship in the armrest portion. question: . That is, the posture of posture or roll is a necessary seat or leaning mechanism, and the problem will be caused by the posture: the patient's stretcher posture. This. This way, it is not necessary to fall off. In order to make it annoying to support the patient from the pillar of weight that is also necessary to support, it will be easy to take this. In the other industry, it is necessary to stretch the strength of the receiver, and the structure is shaken. Comfortable deformation into the thousands of disturbing components, moving to the weight of the bed but the familiar, or the posture of the wheelchair after the armrest is installed and removed so that the time or amount, the frame becomes and cannot be Intentionally, the reversed-phase armrest used by the armrest must be constructed because the unilateral grip can get the foot on the wheel because it is also lowered, which is true. However, the leaning of the back is considered to be forward in the support of the Department of Learning. The posture may be the shape of the chair. It may be that the wheelchair is tilted and rolled down in order to make it real. Know the stretcher. For example, when the patient is caused to slide to the head to use it, if the affected area is in the patient's body or head support structure when the patient cannot use it as a wheelchair, it is deformed and because it does not have support It is used because the patient wants to be in danger. In terms of aspects, there is nothing special: in the end of a board, I have to take measures to increase the jk fluid of the head and fall? Uneasiness

2009-3469-? F.ptd Page 5- 5. Description of the invention (3) _, the time required to move is very short, and the patient will also cause unhappiness or uneasiness. If so, the opposite pillow was placed to hold the head properly = ',,. And, even if it is slipped on the stretcher, or the pillow is lost, etc., not only will the pillow be moved and the head will be fixed to the pad +, the string will be moved to the mountain. However, if the pillow is not applicable. On the other hand, ^ 妷 ^ / will become a hindrance during the development of the transfer, only from the neck: 浐: a stretcher with a head support also: separated and must be regardless of the patient; :: = start The expedient will have to form a single one when it is used; == as a stretcher to support the undressed mule, and it is difficult to make Hou Meng's comfortable posture when used as a wheelchair. Yu Yicut's head, the fourth problem is the movement of the stretcher or the patient's movement on the stretcher. That is, the patient is transferred from & to the stretcher while lying down, or With respect to the care system that is transferred from a stretcher to a bed in reverse phase, for example, the convenience of using a device called a transfer rod to transfer patients is conceivable (International Publication No. W099 / 306 62).

When this transfer lever is used to transfer a patient from a bed or the like to a stretcher, a bracket is provided on the side of the side that is not connected to the transfer lever, and it is also necessary to turn the transfer lever support as possible. Here, since the bracket supporting the transfer rod protrudes above the stretcher, the treatment and treatment of the patient in the case of the device may cause obstacles, troubles, etc., so the stretcher is expected to be made as Removable ° 2009-3469-PF'Otd Page 6 ^ 7 3 ^; l < ^ 'mm.- 89119824 ——_?. year? fi 讥 H Corrected from _____ i 、 Fahu description < 4) Although it is so 'removing the bracket one by one, it will take time to crack and remove', and there must be a bracket after the removal Place. Furthermore, the bracket removed from the stretcher may be lost. Moreover, when the stretcher is pushed, 'because it is a structure that has to hold the frame with the height of or lower than the net surface, the caregiver or caregiver has to bend over the waist and Bend forward to exercise the push and pull of the stretcher, and there is a problem of causing a burden on the waist. Fifth question: The transfer lever is provided to prevent the patient from falling over. That is, although it is necessary to make the transfer rod detachable for the purpose of moving, etc., it is annoying and inconvenient to disassemble each time it is transferred. Furthermore, the storage of the transfer rod after removal is troublesome and may be lost. In addition, a structure in which the transfer lever is moved up and down to avoid it is also conceivable, but in this case, it is also because the width and position of the transfer lever and the supporting structure do not change, Therefore, when a stretcher is placed on a bed or the like, the transfer lever protruding from the cushion to the side hinders the problem of a gap between the stretcher and the bed. The purpose of this hairstand is to change from a stretcher to a stretcher to provide a patient-holding chair for the purpose of providing a chair with high rigidity and excellent durability. Furthermore, the present invention aims to provide a stretcher that can change the shape to a wheelchair in one motion or vice versa, and converts the wheelchair to a stretcher and expands the cushion surface when the shape is extended. Furthermore, the present invention aims at a stretcher that is excellent in posture when used in the form of a stretcher. In addition, the present invention is that the posture of the protector or the caregiver during the movement is a wheel of ease. And ’the present invention is to provide a

Page 7 5. Description of the invention (5) The stretcher of the bracket is for the purpose. Furthermore, the present invention aims to provide a stretcher that can be installed on the edge of the mat as needed and can be retracted to a position that will not cause an obstacle when the patient is transplanted. ^ In order to achieve such an object, the present invention resides in a stretcher having a frame that supports a mule that is mounted on a table and carries a patient, at least the frame can be divided into: a knee that supports a patient's thigh and becomes a sitting part The upper part, the waist part that supports the upper body from the waist to become the back, the armrest part that becomes the armrest and the lower knee part that can support the lower limbs, and the upper knee part, waist part, armrest part and lower knee part are connected into It is possible that Θ turns, and in order to change the positional relationship of these, it includes the armrest part and the lower knee part to make it possible to deform it into a stretcher shape that forms a flat cushion surface and a wheelchair shape that folds and bends to raise the armrest, and makes Its achievement (because of whether it is a stretcher or a wheelchair, it is possible to carry the patient and move it = Therefore, by turning the frame | frame that is connected to be possible to rotate The angles of the armrest and upper knees of the waist, the upper and lower knees, and the angles between the lower knees and the lower knees It can be transformed into a wheelchair shape such as a stretcher that is arranged on a straight line and formed on a rafter surface, and a folding seat that is folded and separated to form a seat stick and a foot with hands. Also, the wheelchair supports a small form : The part of the belly can also be used in the form of a stretcher, because the mat surface will become wider, so as a stretcher, it will be easy to use. Shake it to the bottom of the waist and the middle of the lower knee. Connected to the α car 'and viewed from the side, it forms the waist

So that the waist can be turned backwards, so | I> 丄> The quadrilateral will collapse and on the one hand the four parts will be arranged on the same i-plane, and the other will make the waist part stand forward. And j < line four, the shape will return to its original shape, and it is best to enable the armrest portion to be lifted. In this case, if the waist portion is turned backwards, it will become a stretcher | l, in the armrest While the lower part is lowered, the upper part of the knee will be raised. Because the lower part of the knee will be tilted backward at the same time, it is on the joint line of the two junctions between the trolley and the frame. The lower part of the knee and the waist part forming the backrest will be configured as a straight and open / flat cushion surfaceOn the other hand, if the factory entrance is to be used as a wheelchair, the movement of the waist part can be restored to a parallelogram, and since the armrest part is lifted approximately horizontally, even if it is deformed to lose The chair 'does not need to twist the armrests or attach them in addition to raising the waist. . The knife is lifted and the respective right and left joints of the "stretcher aspect of the present invention" frame are made of a core material that connects one joint and the other joints and options corresponding to the other, And it is formed by a sleeve that is embedded in and fixed to the frame like free rotation in the core material, and the frame can be folded and bent by turning the sleeve around the material and the material. Therefore, the left and right I frames are pivoted because the sleeves are fixed around the core material! In the waist or upper knee, lower knee, armrest

458773 Description of the invention (7) Analytical bends at the joints. Frames on the left and right. Also, the use of sleeves and sleeves is not worried. The joints at each joint are smooth, clear and durable. The total length of the frame is approximately the same as that of the flange used for the tube falling. When the frame is assembled, the flange member on the device can be swiveled to control the cost. And, the pieces come off. As long as the | setting is determined and the “four-link mechanism” of the present invention is lifted or inverted when the locking waist portion is released, locking the locking mechanism will prevent the frame from being deformed into an arbitrary shape. The various parts of the curve make the stand up and cool without any distortion and the contact area of the core material. The sleeve will be deformed or expanded, and it has excellent durability. The bending action ’can either fall or fall, so the frame deforms smoothly. ‘So even if it ’s long, so the connection is the one’ On the one hand, it is to ensure that the rigidity of the frame is all and best. This is because the core material is not productive, so there is no ringing. Structured. In the linkage machine, the shape of the chain will be tightened. The joint is the same as the core component installed in the nuclear casing, and the number of sleeves is the same. The sleeve is made of a flange and a flange member, each of which is a frame for a stretcher, and can be tightened under the state of a fixed coupling mechanism. All in all, angle. It is best for the organization to have the full length of the core material, and the difficult side of the heartwood. After that, the core material will not be supported by the core. Therefore, not only can the components be supported, it can be exercised. It is best to make the tower's frame under the lock's locking machine 'according to the shape of the four or wheelchairs'. The combination of the sleeves of the lock will prevent the sleeve from falling on both ends of the heartwood. In addition, the deformed shape of the situation where the joint can be lifted and can be parallel to the four sides by the bits in the direction of the core axis. Then it is fixed and the frame can be fixed

The angle adjustment mechanism is preferably provided with: a bracket connected to the trolley, which is sandwiched between the frame and the second frame, and swings freely while supporting the frame, and a support member which is freely swinging It is a tilt angle variable mechanism that can be fixed at any position relative to the car. In this case, if the restriction of the support member is released by the tilt angle variable mechanism, the supporting tooth structure 1 and a half are rotated in an arbitrary direction around the support axis between the support frame and the trolley. Of tilt. Here, the maximum inclination position or any inclination position to the connected position, for example, when the branch member is fixed by the inclination angle variable mechanism at a slightly backward position, the inclination is maintained even if the entire frame is maintained.

Thereby, the stretcher can hold the patient's head at exactly i I high f here and take a comfortable posture. Therefore, even if the patient is lying down or sitting, it is possible to obtain a comfortable posture in which the head is supported without causing a burden on the body. The headrest required for the 'stretcher' is to be flat when transferring a patient without interfering with transportation. On the other hand, the patient is lying on his back on the stretcher! It is best to use it when changing the shape of the stretcher to a wheelchair. It is best to fit the patient's posture, symptoms, physique, etc. Height or angle: The degree can be adjusted precisely. Here, the inventor's idea is that it is expected that the above-mentioned adjustment of the height and inclination of the headrest can be performed simply and flexibly, and that the heads of patients with different physiques or symptoms can be adjusted accurately.

Description of the invention (13) The force and the change of the support member can be made here. It is better to move the floor in the direction of overlap. At this time, it is easy to overlap during assembly because the overlapping plates of the side members are interacted with each other. A part of the overlapping plate is preferably such that the gap can be adjusted when the overlapping plate and the tilting layer which become the fixed side member or the tilting side member are fixed. Therefore, the headrest is preferably directed toward the top of the head. The width becomes narrower. In the case of &, the body support function of the headrest can be maintained while holding the handle portion, and the handle portion can be stored in the headrest ㈣, so that the stretcher can be miniaturized when the handle is not used. Moreover, the frame of the stretcher of the present invention is provided with a bracket that can support the patient's soap-free scroll while lying down, and the patient can lie on the bed while the bed sheet is rotated by the transfer rod of the bed transfer stretcher. Part, a rotating shaft part supporting the bracket-shaped part, and a connection that allows the shaft part and the frame to rotate on the same axis, and is fixed to rotate without changing according to the fitting at a predetermined rotating position.

Here, the pipe 2c and the pipe 2a are welded at the upper end to form the back portion 2 as a whole. The combined length of these sleeves 18 to 20 and the total length of the core material 17 are approximately equal. In this embodiment: the total length of all the sleeves 18 to 20 is slightly shorter than the total length of the core material 17, so that the rotation of the sleeves 18 to 20 is smooth. In addition, the tubes 2a | ^, 3a, and the handle 44 may be fixed to a sleeve connected to the sleeves 18 and 19 at a fixed angle according to circumstances. β ‘For example, a core material 17 formed of a pipe material (hereinafter referred to as a core pipe material) 疋: A sleeve 18 to 20 is provided at the end surface 17 a to prevent falling-off. = flange member 21.

On the other hand, if the second locking device 15 a is tightened, it is easy to obtain a large rigidity for locking the frame 1. In the shape of the wheel j chair shown in FIG. 8 and the like, although the second locking device 15b is extended, because the first locking device 15a is in a contracted relationship, the frame 1 is locked. Can get full rigidity. The same ′ is in the form of the stretcher shown in FIG. 1 or FIG. 19 and the like, although the first locking device 15 a is extended

2009-3469-P? Ptd Page 37

However, because the second locking device 15b is in a tight relationship, it is possible to obtain full rigidity for locking the | frame 1. That is, as long as the installation angles of the two locking installations 5a and 1 5b are changed, you can get the regular full | tight rigidity here 'If the gas spring with the locking mechanism is locked In this case, since the crank rocker 35 cannot be rocked, movement of the rear support portion 42 becomes impossible. That is, because the movement of the rear support portion 4 2 is locked, the support member 11 a is fixed and the inclination angle of the frame is maintained. j In this state, because the frame 1 is slightly lowered in the rear as a whole, it can sit deeper and the safety of the patient will increase. Furthermore, since it can sit deeper and deeper, the whole body becomes like a wrapper, and can sit in a more relaxed posture. In the case where the tilt of the frame 1 is restored to the original condition, the gas spring 3 with the locking mechanism is released according to the operation of the cold-rolled handle, and then the frame 1 is lifted to the side, because the rear side of the support member 丨 a Since the support portion 42 can freely move in the relation of j, the support portion 42 rotates around the support shaft 34 and stands forward. With this, as shown in Figure 6, the frame will return to the horizontal state as a whole. In this state, you can easily get on and off in a wheelchair. Next, after the gas spring with the locking mechanism is locked, if the waist portion 3 and the back portion 2 of the frame 1 are turned down, as shown in FIG. 3, the mat surface will be restored to a flat state. Here, the fixation of the trolley 丨 丨 is j 丨; according to the depression of the brake pedal, the brake will be applied to the casters to stop it. ‘In this embodiment’,

The heavy influence is eliminated by the gas springs 37 with two locking mechanisms provided on the left and right of the trolley u. If it is explained in detail with reference to FIG. 16 'for example, when the patient's weight is set to 60 kg, from the rotating shaft 43 which is the center of the crank rocker 35 to the connection part with the gas spring 3? With a locking mechanism The ratio of the distance to the distance to the connecting pin from the rotating shaft 43 is 0.7: 1. Therefore, if the reaction force of the gas spring 37 with the locking mechanism is taken as ^, the force lifted by the connecting pin 39? The result of 2 is: F2 = 0.7.F1. Now, 'the hypothetical patient's weight is 60 kg. The reaction force Fl = 85x 2 = 170 kg. Therefore, it becomes a force F2 = 170x0.7 = 119 kg 'and can support the weight according to the force Fa = l 19 X 0.5 = 59.5 kg. That is, by using two gas springs 37 with a locking mechanism for generating a reaction force of 85 kg, a force Fa of approximately the same size as the weight of the patient can be supported. Therefore, it has little effect on the patient's weight due to the tilting operation. Next, the support mechanism of the headrest seat 7 is demonstrated. The stretcher of this embodiment is provided with a headrest 7 as shown in FIG. 3 and FIG. 25 to FIG. 32 on the patient's head where the tube 2b constituting the back portion 2 of the frame 1 is provided. As shown in FIG. 25, for example, a base 7a formed of a plate material, a plastic plate, a steel plate, or the like, a cushion portion 7b supported by the base 7a, and other coverings covering these are formed. In addition, the headrest seat 7 of this embodiment is configured to be adjustable in height and inclination with respect to the pipe 2b of the back portion 2. Example: The basis shown in Figure 27 is provided with welding

Description of invention (37), etc. are mounted on the bearing bracket 46 of the pipe 2b, and are fixed on the inside of the head foundation 7a with small screws, etc. The second bearing brackets π, 'and the two sleeve sleeves 46, 47 which pass through each other # are connected to each other, and the connecting devices 48 are fastened and fixed to make it possible to adjust the height of the headrest 7 And tilt. As shown in FIG. 25, is it formed as the sub-section of & headrest 7 when located at the lowest position? b. When the 纟 is changed to a stretcher, the 塾 2 can become '^ -like height, and the height of the headrest f 7 buckle pad 27 is not necessarily the same south degree depending on the occasion.' For example: The height of the headrest 7b can also be changed according to the use situation, as the rafters 7b of the headrest 7 are higher than the cushions 27. In addition, the pipe 2b on which the headrest 7 is installed is as shown in Figs. 3 and 25, and the portion of the headrest 7 on which the pipe 2b is shaken in the stretcher form is lower than 2a. It seemed to bend. By the back-off caused by this, a space for accommodating the headrest 7, the first bracket 46, the second bracket 47, and the like is formed, and the mule 27 and the headrest 7 are placed in the same manner. the height of. 1 The positions of the first bracket 46 and the second bracket 47 are respectively provided on the left and right sides of the headrest 7. The first bracket disposed symmetrically on both sides as shown in FIG. 26 is the inner side surface of the pipe η welded as shown in FIG. 27 and FIG. 28. On the other hand, the second brackets 47 and 7 are symmetrically disposed inside the left and right first brackets 46 as shown in FIG. The second bracket has, for example, two threaded holes 47a and 47b ′ shown in FIG. 27 and the holes 47a and 47b are used to fix the headrest 7 to the headrest 7 by bolts or the like. Inside of space 7a. Here, the first bracket 46 and the second bracket 47 are in direct contact with each other, and

4 58 7 73 V. Description of the invention (38) It is also possible to set them together adjacent to each other, but it is best to be between the two brackets 46 I, 47 'by using the friction plate or synthetic rubber that exists Plates, etc., to increase the friction, and then the headrest 7 is firmly fixed. For example, in the present embodiment, as shown in FIG. 27, it is preferable that the frame-side friction plate 54 and the headrest 7 are rubbed between the first bracket 46 and the second bracket 47. Plate 55 forms a set of friction plates. Needless to say: The number of capricorns is not limited to two pieces. 'More than the above may be used' or the left f is arranged on the headrest 7. At least one of the frame groups may be included. D Frame side friction The plate 5 4 is supported by two supporting rods 46 b protruding from the first bracket 4 6 and the bracket 4 6 through two fitting holes 5 4 b so as not to rotate. . Further, "the through hole 54a is perforated at the same position as the through hole 46a of the first bracket 46 of the same friction plate 54". In addition, the headrest seat side rubbing plate 55 is made by passing two support cups 53 protruding from the second bracket 47 with respect to the second bracket 47 through two opening holes 55b. Non-rotating branches are marked with j. Further, at a place where the through hole 47a of the second bracket 47 of the same friction plate 55 is coaxial, the through hole 5 5a is perforated. Here, the headrest-side friction plate 55 and the through holes 47a and 55a of the second bracket 47 are formed with long elongated holes in a direction perpendicular to the tube 2b (the height direction of the headrest). Via this, between the left and right pipe 2b and the headrest 7 respectively, one set of j brackets 46, 47, and two friction plates 54, 55 are as follows: The bracket 46-the friction plate 5 and the friction plate 54-the bracket 47 are arranged in this order, and then they are connected by a connection device 48 formed by one lock bolt 49 and the pipe 51. Here, the “long hole 47a” is best with respect to the tube 2b, and the head seat is best to be turned away if it is likely to be close.

2009-3469-?? p t d p.41 73 V. Description of the invention (39) '. For example, it can be a long hole extending obliquely with respect to the axial direction of the pipe 2b. The connecting device 48 is provided with a left and right frame to sandwich each of them and be placed in the bracket 46 and the second bracket 47 and allow or prevent their relative rotation. + In the present embodiment, this connection The device 48 is tightened by the fastening bolt 49 of the first and second brackets 46'47 on both sides of the Beton as shown in FIG. The second handle 4 is arranged on the left and right sides of the handle 50 and the ^ solid spear 'bolt. The interval is between 4 and 7 | | This interval is maintained at -fixed by the fastening pipe 51 and by the fastening screw It is constituted by inspecting a factory-moving device formed by a 49 ° moment I | shaped head 49a and a rectangular braking hole 46a of the i-th bracket 46. Therefore, it looks like it passes through the left and right second and second brackets 46 and 47, and the fastening pipe 5 as a spacer arranged between the friction plate 55 and the left and right second brackets 0 |. After passing through the fixing bolt, insert the head 49a into the rectangular through hole 46a of the first bracket 46 on one side so that j | = will not rotate and then tighten the handle and tighten it. The head support seat 7 is fixed to the pipe 2b of the back part 2 by the strong tightening of each of the left and right bearing sets via the fixed pipe 51. Therefore, if the handle is loosened slightly, the frictional force generated between the first bracket 46 and the second bracket will be lightened 'and the headrest seat 7 will tilt freely about the bolt 49 as a center. „Furthermore, the fastening bolt 49 is provided to rotate freely with respect to the first bracket 46 and the second bracket 4 ?, and the bracket can also be rotated by turning butterfly screws at both ends | 4 6, 4 7 is fixed. Furthermore, since the flanges are formed at both ends of the fastening material 5 丨, the contact area with the second bracket 4 7 may be increased. According to the above configuration, although the headrest 7 tilt adjustment is possible

73 V. Description of the invention (40) Yes, but in this embodiment, the tilting 4 adjusting mechanism relative to the frame 1 is also provided. The up-and-down moving mechanism is to use the through-hole 46a of the first bracket 46 or ^ ^ # ^ among the through-holes 47a of the second bracket 47 that moves the headrest 7 up and down similarly. Either of these makes it possible to form a high cup plus r / to the headrest 7. In this embodiment, as shown in 圊 27, the stroke range can be up or down. According to this up and down, 头, the headrest seat 7 has both the tilt adjustment function and the height adjustment function, and it can be adjusted to perform tilting at any height. In addition, the headrest 7 is such that it becomes a cushion surface when returning to the headrest retreat position. [2 疋 & The changed mechanism 3 can be realized, for example, when the first bracket 46 and the second bracket 47 which are relatively rotated are located in the retracted position (the state shown in FIG. 25) to cooperate with each other to prevent rotation. The construction. For example, in this embodiment, 'the segmented portion 52 is formed as shown in FIG. 25 and FIG. 26 of the first bracket, and the fixed lock 53 of the second bracket 47 and the second portion 52 are connected to the segmented portion 52. The bracket 47 is provided so as not to be rotatable. The segmented portion 52 is not particularly limited in shape if it can be engaged with the fixing pin 53 at the headrest retreat position, but in the present embodiment, as shown in FIG. 9 in combination with the cylindrical fixing pin 53 The left-right symmetrical arc shape, and the surface pressure dispersion. Moreover, the shape of the first bracket is that only the headrest seat retracted position is engaged with the fixing pin 53 and the headrest seat is pulled up as if separated from the official material 2b.

/ 3 ί ~ " ~~ " " ~ —1 | V. Description of the Invention (41) I was formed into a shape other than the movement of the fixed pin 53 that would not hinder the return of the second bracket 47 . For example, in the present embodiment, as shown in FIG. 26 and the like, a semicircular shape having a center upper portion of the first bracket 46 centered on the through hole 46a is formed. In this case, if the headrest seat 7 is pulled up as shown in FIG. 30, when the tilt is formed as shown in FIG. 31 and FIG. 32, because the j | segmented portion 52 of the first bracket 46 and Since the fixing pins of the second bracket 47 do not collide with each other, the tilt of the second bracket 4 is not prevented, that is, the tilt of the headrest 7 is not prevented. And, the headrest 7 is such that it is possible to adjust the tilt at all positions except the headrest seat retracted position, even if the upper stroke end of the long through hole 47a is not reached. And the tilting range of the headrest seat 7 at the position where the through hole 47a is long is determined according to the shape of the segmented portion 52 or the relative position of the fixed pin 53. |

; I When the headrest 7 configured as above is changed to a stretcher as shown in Figures 丨 and 3, according to the descending position of the headrest, it forms a flat surface with the cushion 27 at the same time, or When changing to a wheelchair as shown in FIG. 2, the surface of the back part 2 becomes a flat surface. At this time, the fixing pin 53 with the second yoke 47 is based on the engagement with the segmented portion 52 of the first bracket 46, so that the headrest seat 7 will be kept at the same height as the other mat surface. The level of 'does not cause obstacles when transferring the patient between the stretcher and the wheelchair ^ In this case', by closing the connecting device 48 in advance, the unexpected movement of the headrest 7 can also be prevented. And 'When it is necessary to adjust the height and angle of the headrest 7, turn the handle 50 to loosen the fastening bolt 49' to allow the relative | j movement between the first bracket and the second bracket 47 to move. Turning is possible ' Raise the headrest 7 as shown in Figure 30

2D09-3469-??-ptd page 44/3 5 'Explanation of the invention (42) "' --- Greek degree. If the headrest 7 is pulled up, since the fixing pin M will be separated from each other, the headrest 7 can be tilted as shown in FIG. 31 or FIG. 32. Therefore, after obtaining the desired height and angle, the handles may be closed and the first and second brackets 46 and 47 may be fixed by friction. If the headrest 7 is tilted to the patient side as shown in Fig. 3, a wide holding surface along the back of the head can be obtained, and if it is tilted to the opposite side as shown in Fig. 3, although the area for holding the back head is reduced, it can be easily secured height. In addition, when the headrest seat 7 is in a wheelchair form, it goes without saying that the headrest seat 7 is moved forward and backward. The headrest 7 is, for example, in the form of a stretcher, if the handle 50 is released, it will automatically return to the original headrest retreat position. In this case, since the fixing pin 53 is engaged with the segmented portion 52 to determine the position, the headrest seat 7 naturally becomes a horizontal state and becomes a surface with the mat surface u 2. Therefore, even in a state where the patient must be moved quickly and safely, it is possible to quickly and surely return the headrest 7 to the headrest retracted position ', and it is possible to provide the patient with a transfer or movement.

20fl9-3469-PF- ?: d p. 45. In this embodiment, the segment portion provided on the i-th bracket 46 is engaged with the fixing pin 53 provided on the second bracket 47. The position of the headrest seat 7 is determined, but the appearance of determining the position is not particularly limited. For example, as shown in FIG. 27, the fitting pin 46b provided to fit the frame-side friction plate 54 to the third bracket 46 can be used to determine the position of the headrest seat 07. In this case, the second bracket 47 and the friction plate M on the headrest side, if necessary, are provided only when the headrest 7 is in the headrest retracted position. The segmented portions of the joint pins 46b to be simultaneously connected may be sufficient. According to this, the position of the head D seat 77 458773 5 'invention description (43)-can be determined similarly to the above-mentioned embodiment.

I Here 'The above-mentioned headrest 7 is described as an embodiment configured with a plate shape that cannot be deformed. However, depending on the occasion, the backrest 7 can also be bent. Structure: For example, the core material of the headrest 7 shown in FIG. 33 can also be divided into: a fixed core material 7 fixed to the center of the official material 2 b and a core connected to the fixed core material to be movable. The two sides of the caustic core material 71, 72 have three niches. 'The left movable core material 7 1 and the right movable core material 7 2 are connected by a bendable mechanism 73 that can be bent, and the patient's head can be held from one side or both sides ^ And, as in the embodiment, The headrest seat 7 has a fixed core material 70 having a substantially rectangular shape, and a left-side movable core material 71 and a right-side movable core material having a symmetrical table shape, and is perforated at each of the core materials 70 to 72. There are through-holes 70a, 7la, and 72a of the fixed-side member 57 and the movable-side member 5δ for the flexible bending mechanism 7 3, and the fixed core material 70 is perforated to install the headrest 7 on the Frame ^ 's through-hole soup of the tube Shan. The flexible mechanism 73 is as shown in FIG. 36 to FIG. 43. The fixed side member 57 and the movable core member 72 mounted on the fixed core material 70 are attached to the human body by means of a pinch 媸 and soil 1 ^ Hunting is a combination of a folded leaf structure that can bend it. The reason is that for the convenience of explanation, the description of the present invention refers to the-side as the fixed side and the other side as the movable side, but ==, also / not ^ are relative things, such as only the When the two members on the movable side are formed, 'it can be considered. The fixed-side member 57 is a base coffee as shown in FIG. 38, and

The number of the overlap plates 59 and 60 is not particularly limited. For example, as shown in the present embodiment, although the total number is four, it does not matter whether it is more or more. For each of the overlapping plates 59 and 60, as shown in FIG. 39 and FIG. 40, the claws 59a and 60a provided for mounting on the base plate 61 are provided with the base plate 61 provided with the claws 5 9 a, 6 0 a mounting hole. Moreover, as shown in FIG. 37, the thing mounted on the end of the substrate 61 in the plurality of mounting holes 61a may be a mounting groove. The plurality of overlapping plates 59 and 60 are arranged in parallel with a desired interval provided by the substrate n on the fixed side. In this embodiment, the arrangement interval is set to! A certain interval ', and the interval interval is such that it can be consistent with the thickness of the overlapping plates 59, 60. Although the overlapping plates 59 and δ0 are all relatively fixed to the substrate 61, it does not matter. Among the four plates, it is preferable that the two plates located at the inner position j can be slightly inclined as shown by circle 43. The four overlapping plates 59 δ of the fixed side member $ 7 and the movable side member 58 are inserted and coordinated with each other. It is easier to make the plates 59, 60 drill into each other's space during stacking. I In this embodiment, the two overlapping plates 5 9 arranged on the outside are fixed to the base plate 6 1 so they have a position as shown in FIG. 39 and are embedded in the mounting holes (mounted) 61 a * and The projection-shaped claw 59a is more suitable for welding or other fixing methods. On the other hand, since the two overlapping plates 6 arranged on the inside are movable relative to the substrate 6, it is not necessary to fix them to the substrate 61 by welding or the like, and the fitting claws 6 are not required. 〇a Hook on the base plate 61 | Shi Li (Ha and fit it.

With respect to the fixed overlap plate 59, the movable overlap plate 60 can be slightly inclined toward any fixed overlap plate 59. And, through holes 59b and 60b shown in FIG. 39 and FIG. 40 are provided on the overlapping plates 59 and 60. The through holes 59b and 60b are as shown in FIG. 42 because they penetrate through the connecting shaft 64 which becomes the center of tilting. So that the fixed-side member 57 and the movable-side member 58 and the respective through holes 59b, 60b can be matched with each other in a consistent manner! After overlapping, 're-insert the connecting shaft 64' and then tighten it with a nut 66, so that The fixed-side member 57 and the movable-side member 58 are connected to each other so that they can rotate. As described above, the fixed-side member 57 is constituted by mounting the overlapping plates 59 and 60 on the base plate 61, but the other movable-side member 58 has the same structure as the fixed-side member 57. For example, in this embodiment, as shown in FIG. 37, the place where the mounting hole (clamping groove) 62a is provided is the same as that of the fixed i-side substrate 61.

Description of the invention (46) --- As described above, the overlapping side plates 59 and 60 having the same shape as the fixed side member 57 are installed to form the movable side member 58. The through holes 615 and 621 in the substrate are devices for fastening the fixed-side member 57 and the movable-side member 58 to the headrest 7 as shown in Figs. 33 and 35. '' The fixed-side member 57 and the movable-side member 58 formed in this way are mutually expanded as shown in FIG. 40, and the fixed overlap plate 59 and the movable overlap plate 60 are alternately expanded, and then the pin 64 is connected by the connecting shaft 64 to form a function. The leaf-shaped Of curved mechanism of buckling. In this embodiment, when the fixed side member 57 and the movable side member 58 are opened to 180 degrees as shown in FIG. 38 and FIG. 39, the inner edges of the two substrates “62 are in contact with each other, and the tension is prevented. The opening is larger than the above. Therefore, 'This flexible mechanism that may buckle? 3 is the maximum opening angle up to =: the tilt can be adjusted within the range, and the headrest is used as a mechanism / use in this embodiment. The two movable core materials 72 of 7 will be flat when they are opened to the maximum. # 时时 时 t The above-mentioned Yuyan, which weighs 60 sections of the fixed overlap plate 59 and the movable overlap plate, can maintain the contact friction between the overlapping portions.

In this embodiment, as shown in the figure, the left movable core material 7 1 and the right movable core material 7 2 are connected to the central fixed core material 70 according to the two flexible mechanisms 7 3 respectively. It is also possible to connect with each single flexible mechanism 73. Moreover, although each adjustment of the tightening force of each flexible mechanism 73 is made independent; iExercise > but by connecting the connection shaft 6 4 etc. makes simultaneous adjustment of two adjustments possible. In addition, the headrest seat 7 may be divided into two equal parts so that the tilt can be adjusted into a V shape. If the headrest seat 7 is configured as described above, since one or both sides of the headrest seat can be bent as needed, the patient's head can be appropriately supported. Moreover, because the left movable core material 71 and the right movable core material 72 are independent and inclined, each household can not only fold it into a desired shape, but also because there are no two sides lower than the center The situation 'so there will not be a situation where the head slips.
