Description

  The present invention relates to a bed apparatus in which a head board and a foot board as board bodies are provided at one end and the other end in a longitudinal direction.

  In general, the bed apparatus includes a bed frame. The bed frame has a pair of side members arranged in parallel and spaced apart from each other at a predetermined interval. One side of the side member in the longitudinal direction is a headboard as a board body, and the other end is a foot as a board body. A board is provided. The pair of side members, the head board, and the foot board constitute the bed frame having a rectangular frame shape.

  And in the frame of the bed frame, a floor plate is supported by the side member, and a mattress, for example, is placed as a bedding on which the user lies on the floor plate.

  When the user of the bed apparatus is a sick person, a physically handicapped person, or dementia, care for the user on the mattress may be required. When a user is cared, it is usually performed from the lateral direction of the bed apparatus, that is, from the side member.

  By the way, when caring for the user's head, such as washing the hair or wiping around the neck, it is more efficient with less burden on the headboard side than on the side of the bed device. Can be done. Similarly, when performing care on the foot side such as wiping the user's leg or cutting the toenail, it may be better to work from the footboard side.

  However, as described above, the conventional bed apparatus has a headboard at one end in the longitudinal direction of the bed frame and a footboard at the other end. I couldn't do it from the headboard side, and I couldn't care for the foot side from the footboard side.

  Therefore, a bed apparatus is constituted by a pair of guide members erected in parallel, and a panel member whose both ends in the width direction are slidably supported by these guide members. Proposed.

Japanese Patent No. 4491433

  According to the bed apparatus having the above-described configuration, the caregiver can perform care on the user's head side from the headboard side or care for the foot side by removing the panel member from between the pair of guide members during care. Can be performed from the footboard side.

  However, the conventional bed apparatus has a structure in which the panel member is simply slidably held between the pair of guide members of the board body.

  Therefore, since the panel member can be easily slid along the guide member, in the case where the user is a patient with dementia, for example, the panel member may be pulled up and removed from between the pair of guide members. .

  Further, since the panel member is slidably provided between a pair of guide members, it may be easily rattled or may be inadvertently raised when a slight external force is applied to the panel member. There was also a risk that a foot or a finger of a hand could be caught at the lower end.

  The present invention enables the panel member to be removed from between the pair of guide members when the user's head side or foot side is cared, and the panel member can be securely held non-slidable when not caring. It is to provide a bed apparatus.

  As shown in FIG. 3, a leg member 18 having a connecting piece 17 fixed to the upper end is guided and supported by a member (not shown) so as to be movable. Thereby, the leg member 18 can move in the vertical direction relative to the guide member 12. A disc-shaped support member 19 larger than the lower end opening of the guide member 12 is attached to the lower end of the leg member 18.

  As shown in FIG. 2, on the inner surface of the lower horizontal member 11 of the foot board 4, there is provided a drive motor 22 that constitutes a drive mechanism 21 that drives the bed frame 1 in the vertical direction along the leg member 18. It has been. An output unit 23 is connected to the drive motor 22.

  One end of an output shaft 24 that is rotationally driven by the drive motor 22 through the output unit 23 is attached to the output unit 23. The output shaft 24 is disposed at one end portion in the width direction on the lower surface side of the floor plate body 6 so as to be rotatable along the longitudinal direction of the bed frame 1.

  One end of the output shaft 24 protrudes into the lower horizontal member 11 of the footboard 4 and the other end protrudes into the lower horizontal member 11 of the headboard 3 so as to be rotatably supported.

  As shown in FIG. 3, inside each lower horizontal member 11 (only the lower horizontal member 11 of the footboard 4 is shown), screw shafts 26 whose both ends are rotatably supported by the bearing unit 25 are along the longitudinal direction. Is provided. A nut body 27 is screwed onto the screw shaft 26.

  When the screw shaft 26 is driven to rotate, the nut body 27 does not rotate with the screw shaft 26 and moves inside the lower lateral member 11 along the axial direction of the screw shaft 26. The transverse member 11 is supported so as not to rotate.

  One end of a first wire 28 and a second wire 29 is connected to the nut body 27 at a lower portion and an upper portion, respectively. The first wire 28 led out from the nut body 27 engages with the first pulley 31 and is turned upward, and the other end is one leg located on one end side in the width direction of the footboard 4. The member 18 is connected to the connecting piece 17 provided at the upper end of the member 18. The first pulley 31 is rotatably attached to a first bracket 30a fixed in one longitudinal end portion of the lower lateral member 11.

  The second wire 29 engages with a second pulley 32 that is rotatably attached to the first bracket 30a near the first pulley 31, and is horizontally changed in direction. The lateral member 11 is guided to the other end side in the longitudinal direction.

  A second bracket 30b is fixed in the other end portion of the lower lateral member 11. A third pulley 33 and a fourth pulley 34 are rotatably attached to the second bracket 30b in the vertical direction. The second wire 29 whose direction has been changed by the second pulley 32 is sequentially engaged with the third and fourth pulleys 33 and 34 and is turned upward in the vertical direction.

  The other end of the second wire 29 is connected to the connecting piece 17 provided at the upper end of the other leg member 18 located on the other end side in the width direction of the footboard 4.

  The output shaft 24 and the screw shaft 26 projecting into the lower horizontal member 11 of the head board 3 and the foot board 4 are arranged with their axes orthogonal to each other. A first gear 36 is fitted to one end and the other end of the output shaft 24 (only one end is shown in FIG. 3). The first gear 36 meshes with a second gear 37 provided at one end of the screw shaft 26 with the first gear 36 and an axis orthogonal to each other.

  Therefore, when the drive motor 22 is operated and the output shaft 24 is rotationally driven via the output unit 23, the screw shaft 26 is interlocked with the rotation of the output shaft 24. When the screw shaft 26 rotates, a nut body 27 screwed into the screw shaft 26 moves inside the lower lateral member 11 in accordance with the rotation direction of the screw shaft 26 along the screw shaft 26 in FIG. It moves along the direction indicated by arrow A or arrow C.

  When the nut body 27 is moved in the direction indicated by the arrow A, for example, one end portions of the first wire 28 and the second wire 29 are drawn into the lower lateral member 11. Accordingly, the lower lateral member 11 and the guide member 12 and the side member 2 provided integrally with the lower lateral member 11 are driven in the upward direction relative to the leg member 18. That is, the bed frame 1 is driven in the upward direction along the leg member 18.

  Conversely, if the screw shaft 26 is rotationally driven so as to move the nut body 27 in the direction indicated by the arrow C, the first and second wires 28 and 29 are drawn into the lower lateral member 11. Since the portion is drawn out from the lower horizontal member 11, the bed frame 1 is lowered by its own weight according to the length of the wires 28 and 29 drawn out.

  That is, the drive mechanism 21 including the drive motor 22, the output unit 23, the output shaft 24, the screw shaft 26, the first and second wires 28 and 29, the first to fourth pulleys 31 to 34, and the like described above. Accordingly, when the drive motor 22 is operated, the output shaft 24 drives the pair of front and rear board bodies, that is, the screw shafts 26 provided on the head board 3 and the foot board 4 in synchronization.

  When each screw shaft 26 provided on each head board 3 and foot board 4 is driven synchronously, a nut body 27 screwed to the screw shaft 26 is shown in FIG. 3 according to the rotation direction of the screw shaft 26. To the direction indicated by the arrow A or C, and the first and second wires 28 and 29 are driven in the pulling direction indicated by the arrow A or the feeding direction indicated by the arrow C.

As a result, the guide members 12 provided on both sides of the head board 3 and the foot board 4 move in the ascending or descending direction along the leg members 18 respectively, so that the bed frame 1 that is integral with the guide member 12 is provided. One end side and the other end side in the longitudinal direction can be simultaneously driven in the vertical direction at the same height.

  That is, the bed frame 1 can be adjusted in height while maintaining a horizontal state. FIG. 1 shows a state where the bed frame 1 is raised to the highest position, and FIG. 9 shows a state where the bed frame 1 is lowered to the lowest position, that is, a position where the bed frame 1 approaches the floor surface.

  The driving of the bed frame 1 by the driving mechanism 21 can be controlled and set via a control device 38 by a remote controller (not shown). The control device 38 is provided on the inner surface of the lower horizontal member 11 of the foot board 4 as shown in FIG. 2, and constitutes control means with the remote controller.

  The height adjustment of the bed frame 1 by the remote controller can be performed steplessly between the lowest position and the highest position of the bed frame 1.

  As shown in FIGS. 7A to 7C and FIGS. 8A and 8B, the stopper device 16 has a housing 41 having an upper surface opened and an interior space 41a. The upper surface opening of the housing 41 is closed by a lid 42. The lid 42 is fixed to the casing 41 with screws.

  A slider 43 is accommodated in the casing 41 so as to be slidable along the longitudinal direction of the casing 41. A stopper shaft 44 projects from one end surface of the slider 43 in the sliding direction, and a locking shaft 45 projects from the other end surface.

  The stopper shaft 44 is slidably inserted through a through hole 46 formed in one end wall of the casing 41 in the longitudinal direction. The through hole 46 communicates one end in the longitudinal direction of the accommodation space 41a to the outside.

  Between the other end surface of the slider 43 and the inner surface of the other end wall in the longitudinal direction of the housing 41, a coiled spring 47 is provided with one end engaged with the locking shaft 45. . The spring 47 urges the slider 43 so that the stopper shaft 44 projects outward from the through hole 46 as shown in FIG.

  On the upper surface on the other end side of the slider 43, a concave holding portion 48 is formed over the entire length in the width direction orthogonal to the sliding direction. As shown in FIG. 7A, the holding portion 48 is provided with an operation member 52 made of a shaft member having a quadrangular cross section provided with finger hook portions 51 at both ends.

  Both end portions of the operation member 52 provided with the finger-hanging portions 51 are protruded outwardly through the notch portions 53 formed on both side walls of the casing 41 so as to be opened at the upper end surface. As shown in FIG. 7C, the notch 53 has a receiving portion 54 that is shallower than the holding portion 48 formed in the slider 43, a depth deeper than the receiving portion 54, and the same depth as the holding portion 48. The engaging portion 55 is formed in a step shape.

  When the slider 43 is slid by being urged by the spring 47, as shown in FIGS. 7A and 8A, the front end surface of the slider 43 is formed with a through hole 46 of the housing 41. The operation member 52 hits the inner surface of the other end wall and is in a position supported by the receiving portion 54 of the notch 53 which is shallower than the receiving portion 54.

  From the state in which the slider 43 is urged by the spring 47, a finger is put on the pair of finger hooks 51 of the operation member 52, and the slider 43 is moved together with the operation member 52 while compressing the spring 47. Is slid until it hits the vertical surface of the cutout portion 53 on the engagement portion 55 side, the operation member 52 is positioned on the engagement portion 55.

  In this state, when the operation member 52 is displaced downward as shown in FIG. 8B, the operation member 52 is engaged with the engagement portion 55. Accordingly, the slider 43 is held immovably in the housing 41 by the restoring force of the compressed spring 47.

  That is, as shown in FIG. 8B, the slider 43 has a state in which the stopper shaft 44 provided at one end protrudes from the through hole 46 of the housing 41 as shown in FIG. 8A. It enters into the through hole 46 and is held in a non-slidable state.

  The holding state of the slider 43 held by engaging the operating member 52 with the engaging portion 55 can be released by lifting the operating member 52 and releasing the engagement with the engaging portion 55. That is, when the release of the holding state is released and the slider 43 slides, the stopper shaft 44 enters the through hole 46 as shown in FIG. 8 (b), as shown in FIG. 8 (a). Projecting from the through hole 46.

  The stopper device 16 having the above-described configuration is screwed and fixed to the lower end surface of the panel member 13 with the lid 42 closing the upper surface opening of the housing 41 facing upward.

  In a state where the panel member 13 is inserted between the pair of guide members 12, the stoppers of the pair of stopper devices 16 provided at both ends in the width direction of the panel member 13 as shown in FIG. When the shaft 44 is protruded from the through hole 46 of the housing 41, the stopper shaft 44 engages with an engagement hole 56 formed in the lower end portion of the flat surface 12 b of the protrusion 12 a of the pair of guide members 12. To do.

As a result, the lower end portions at both ends in the width direction of the panel member 13 are held by the pair of stopper devices 16 so as not to slide on the pair of guide members 12.
A spacer member 57 having a height dimension slightly larger than the height dimension of the stopper device 16 is provided at a portion between the pair of the stopper devices 16 on the lower end surface of the panel member 13 as shown in FIG. It has been.

  When the panel member 13 is inserted between the pair of guide members 12, the spacer member 57 hits the upper surface of the lower lateral member 11, and the stopper device 16 provided on the lower end surface of the panel member 13 is It is prevented from directly hitting the upper surface of the member 11.

  Thereby, when the panel member 13 is inserted between the pair of guide members 12, the stopper device 16 receives an impact and prevents the holding state of the slider 43 by the operation member 52 from being inadvertently released. ing.

  According to the bed apparatus B described above, the head board 3 and the foot board 4 are inserted between the lower horizontal member 11, the pair of guide members 12 erected on both ends of the lower horizontal member 11, and the guide members 12. The panel member 13 is configured to be detachable. When the panel member 13 is inserted between the pair of guide members 12, the panel member 13 can be held and fixed by the stopper device 16 so as not to be detached.

  Therefore, when the user lying on the bed apparatus B cares for the head side, such as washing the head, the operation member 52 of the stopper device 16 is operated, and the panel member 13 of the stopper device 16 is operated. The holding and fixing state is released, and the panel member 13 is slid upward and removed from the pair of guide members 12.

  As a result, the caregiver can perform care on the head side of the user who is lying on the bed apparatus B from the space where the panel member 13 on the headboard 3 side is removed. Moreover, it can be performed efficiently.

  Similarly, when performing care on the foot side of the user, the care work on the foot side can be easily and efficiently performed by removing the panel member 13 of the foot board 4.

  In the bed apparatus B, a leg member 18 is slidably inserted into the guide member 12, and a protruding length of the leg member 18 from the guide member 12 can be controlled by a drive mechanism 21.

  That is, the support height of the bed frame 1 of the bed apparatus B can be lowered to a low position approaching the floor as shown in FIG. 9 or as shown in FIG. Therefore, when performing care on the user's head side or foot side, the height of the bed frame 1 can be changed according to the type of care work so that the care can be easily performed. It is possible to perform the care work on the head side and the foot side efficiently and with a reduced burden on the worker.

  Most of the drive mechanism 21 that adjusts the height of the bed frame 1 is accommodated in the lower lateral member 11 that constitutes the headboard 3 and the footboard 4. Therefore, since the dedicated space required for providing the drive mechanism 21 can be reduced, not only can the bed apparatus B be prevented from increasing in size, but also the degree to which the drive mechanism 21 is exposed to the outside can be reduced. The appearance of the bed apparatus B can be improved.

  A stopper device 16 for fixing the panel member 13 of the head board 3 and the foot board 4 to the pair of guide members 12 is provided on the lower end surface of the panel member 13.

  The lower end portion of the panel member 13 is not only a position where it is difficult for a user on the mattress to touch, but is hidden by a bedding such as a mattress placed on the upper surface of the floor plate body 6. Therefore, it is possible to prevent a user who is supine on the mattress from inadvertently touching the operation member 52 of the stopper device 16 and releasing the fixed state of the panel member 13 by the stopper device 16.

  For example, when the user is a patient with dementia and the like, the operation member 52 of the stopper device 16 is in a position where it is difficult to operate, thereby preventing the panel member 13 from being meaninglessly removed and carried around. Sometimes it can be done.

  The stopper device 16 is provided on the lower end surface of the panel member 13. That is, the stopper device 16 is not provided at the upper end portion of the head board 3 and the foot board 4 that the user frequently touches or the side end portion that is easily touched by the body.

  Therefore, the stopper device 16 does not cause discomfort by touching the user's hand or body, and does not impair the appearance of the headboard 3 and footboard 4.

  By providing a stopper device 16 for fixing the panel member 13 to the pair of guide members 12, in order to remove the panel member 13 from the pair of guide members 12, the stopper device 16 is operated. An operation for releasing the locked state of the panel member 13 by the stopper shaft 44 (holding state) and an operation for sliding the panel member 13 upward after the release are required.

  That is, two operations, that is, the operation of the stopper device 16 and the sliding operation of the panel member 13 are required, and this also prevents the locked state of the panel member 13 from being inadvertently released. be able to.

  Further, in order to release the locked state of the panel member 13 by the stopper shaft 44, the slider 43 biased by the spring 47 of the stopper device 16 as shown in FIG. As shown in FIG. 3, the operation member 52 is slid against the urging force of the spring 47 to remove the stopper shaft 44 from the through hole 46 of the housing 41.

  Next, the operating member 52 is displaced downward, the operating member 52 is engaged with an engaging portion 55 of a notch 53 formed on the side wall of the housing 41, and the slider 43 is moved by the restoring force of the spring 47. Must be held so that it does not slide.

  That is, in order to release the locked state of the panel member 13, after the slider 43 is slid, the operation member 52 is displaced downward and engaged with the engagement portion 55. Therefore, the locked state of the panel member 13 can be prevented from being inadvertently released.

  Furthermore, in order to release the locked state of the panel member 13 by the stopper shaft 44, the fingers are respectively hung on the finger rest portions 51 at both ends of the operation member 52 protruding outward from both sides of the housing 41, The slider 43 must be slid together with the operation member 52.

  Finger hooks 51 at both ends of the operation member 52 protrude from the lower end of the panel member 13 to one side and the other side of the panel member 13. In addition, the guide member 12 is located at the end of the panel member 13 in the width direction.

  Therefore, when performing the unlocking operation of the locked state, if one finger of one hand is hung on one of the pair of finger hanging portions 51 of the operation member 52 and the other finger hanging portion 51 is not hung on the other hand, The operation member 52 cannot be slid. That is, since the unlocking operation of the locked state cannot be performed without using both hands, the unlocking operation of the locked state is not performed carelessly as in the case of a structure that can be easily performed with one hand. .

  The protrusion 12a of the guide member 12 and the groove 14a of the panel member 13 are slidably engaged. Moreover, by engaging the flanges 14d forming the concave grooves 14a with the concave portions 12c formed on both sides of the ridges 12a, the flat surfaces 12b of the ridges 12a and the flat surfaces 14c of the concave grooves 14a are formed. It is in contact.

  Therefore, the panel member 13 can be slid without rattling against the guide member 12. In addition, since the panel member 13 in the lowered position is held and fixed to the guide member 12 by the stopper device 16, even if an inadvertent external force is applied to the panel member 13 in the lowered position. There is no.

  The present invention can be variously modified. For example, a structure is adopted in which a wire is pushed and pulled by a nut body provided on a screw shaft as a drive mechanism for driving a guide member of a bed frame in the vertical direction with respect to a leg member.

  Instead, the guide member and the leg member may be connected by a driving means such as a cylinder or a linear guide, and the guide member may be driven in the vertical direction with respect to the leg member.

  In the above-described embodiment, the case where the panel members are provided on both the head boat footboards and the stopper devices are provided on both the panel members has been described as an example, but the bed device has one end side of a pair of side members. A headboard, which is a board body, is provided, but a footboard is not provided on the other end side, and a band plate-like end member may be simply connected to form a bed frame.

  In the bed device having such a configuration, the stopper device is applied only to the headboard.

  Although the example which provides the said stopper apparatus in the lower end surface of the said panel member was given and demonstrated, you may make it provide the said stopper apparatus in the part except the upper end part of the said panel member. That is, you may make it provide not only the lower end surface of the said panel member but a side part. Moreover, it is preferable to provide not on the inner surface side of the panel member but on the outer surface side on which the user on the mattress is difficult to touch.

  As a result, even when the user stands on the mattress, for example, when the user touches the upper end of the panel member or leans on the panel member, the stopper device touches or hits the user. It can prevent giving pleasure. Furthermore, since the stopper device is provided on the outer surface of the panel member, it may be possible to prevent the user from performing unnecessary operations.
