Detailed ways

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In addition, below, as a bed apparatus of this invention, the children's bed used for the medical treatment of a child patient in a medical facility is mainly illustrated and demonstrated.

Fig. 1 is a first perspective view of a child's bed 1 according to an embodiment of the present invention. FIG. 2 is a side view of the child's bed 1 . As shown in FIGS. 1 and 2 , the children's bed 1 includes a support stand 10 movably installed on a flat installation surface S, and a bed 20 supported on the support stand 10 .

In addition, in the following description, the direction perpendicular to the installation surface S of the child's bed 1 is defined as the height direction, the longitudinal direction of the bed 20 in plan view is defined as the front-rear direction, and the direction perpendicular to the front-rear direction in plan view is defined as The direction is defined as the left and right direction.

In the height direction, the direction in which the bed 20 approaches the installation surface S (the direction indicated by the arrow D) is defined as the lower side, and the direction away from the installation surface S (the direction indicated by the arrow U) is defined as the upper side.

In addition, in the front-rear direction, the head side direction (the direction indicated by the arrow H) of the child patient (not shown) placed on the bed 20 is defined as the rear side, and the direction (the direction indicated by the arrow H) of the child patient's foot side ( The direction indicated by arrow F) is defined as the front side.

In addition, in the left-right direction, the left-hand side of the child patient lying on the bed 20 (the direction indicated by the arrow L) is defined as the left side, and the right-hand side of the child patient lying on the bed 20 is defined as the left side. The direction of (the direction indicated by the arrow R) is defined as the right side.

The support stand 10 includes a mechanism for supporting the bed 20 in a horizontally movable manner, a mechanism for supporting the bed 20 in a vertically movable manner, and a mechanism for supporting the bed 20 in a tiltable manner. Specifically, the support stand 10 includes: a pair of left-right symmetrical legs 11; casters 12 rotatably attached to the top ends of the legs 11 around an axis extending in the height direction; and supporting the bed 20 to be raised and lowered in the height direction A free elevating mechanism 13; and a tilting mechanism 14 that supports the bed 20 as a tilting mechanism 14 freely about an axis extending in the left-right direction.

Each leg portion 11 includes a linear portion 11a extending linearly in the front-rear direction, a curved portion 11b extending curvedly from both ends of the linear portion 11a in plan view, and a foot tip portion connected to these curved portions 11b and extending linearly 11c; and a caster mounting portion 11d fixed to the ends of these foot tip portions 11c by welding.

In a plan view of the pair of legs 11, the straight portions 11a are parallel to each other, the curved portions 11b are curved so as to be spaced apart from each other in the left-right direction, and the tip end portions 11c extend further away from each other in the left-right direction.

Since each leg part 11 has the shape as mentioned above, between the bed 20 and the installation surface S, the vacant space is respectively formed in the front side, the rear side, the left side, and the right side. As a result, it is difficult for the feet of medical practitioners, such as doctors and nurses, to interfere with each of the leg portions 11 , and thus it is easy to approach the bed 20 from either side of the front, rear, left, and right sides. Moreover, various medical equipment (illustration omitted) can also be arrange|positioned close to the bed 20 by utilizing the said vacant space.

In addition, the linear part 11a is not cut|disconnected at the center position of the longitudinal direction, but a part of the center is covered by the rubber cover 13d mentioned later. Thereby, each leg portion 11 extends from one foot tip portion 11c to the other foot tip portion 11c via the curved portion 11b, the straight portion 11a, and the other curved portion 11b, so that one long plate member is horizontally aligned. A single piece obtained by bending at two places is the main structural element, and caster mounting portions 11d are welded and fixed to both ends of the single piece.

A rubber plug 11e covering the opening is fitted into the upper end of each caster mounting portion 11d, and when the rubber plug 11e is removed, for example, the drip rod 100 (see FIG. 2 ) can be inserted into the opening and used as a support . In addition, in the present embodiment, for reference, only the child bed 1 to which the drip rod 100 is attached is shown in FIG. 2 .

Each of the casters 12 includes: a rotation shaft (not shown) attached to the caster mounting portion 11d so as to be rotatable about an axis parallel to the height direction; a wheel 12a attached to the rotation shaft; and a stopper that allows or locks the rotation of the wheel 12a. moving piece 12b. In this way, by providing the plurality of casters 12 on the support stand 10, the child's bed 1 can be moved on the installation surface S. As shown in FIG.

The elevating mechanism 13 includes a square tube-shaped pedestal portion 13a that is welded and fixed to be sandwiched between a pair of linear portions 11a and extends in the height direction, and an elevating portion 13b that is the same as the pedestal portion 13a. A shaft is inserted into the base portion 13a so as to be able to move up and down in the height direction; a gas spring (not shown) is provided between the base portion 13a and the lift portion 13b; a lift rod 13c allows the lift rod 13c to and prohibiting the lifting movement of the lifting portion 13b; and the rubber cover 13d covering the welding portion between the base portion 13a and the pair of linear portions 11a.

The pedestal part 13a is being fixed to each linear part 11a so that the lower end may protrude more downward than each lower edge of a pair of linear part 11a. By lowering the height position of the base portion 13a in this way, the position of the center of gravity of the child's bed 1 is lowered, so that the stability of the child's bed 1 can be further improved. The lift portion 13b has a square tube shape thinner than the pedestal portion 13a. The above-mentioned gas spring urges the elevating portion 13b relatively to the upper side in the height direction with respect to the base portion 13a.

The lift rod 13c is provided on both the left and right sides in a state where the lift portion 13b is sandwiched therebetween in a plan view, so that the lift rod 13c can be operated from either the left side or the right side of the bed 20 . In a state where the lift lever 13c is not operated, the lift operation of the lift portion 13b (that is, the lift operation of the bed 20) is prohibited (locked). On the other hand, when the lift portion 13b is unlocked by the operation of the lift lever 13c, the lift portion 13b (ie, the bed 20) is gradually raised upward in the height direction by the urging force of the gas spring.

In addition, in a state where the lock of the lift portion 13b is released by the operation of the lift lever 13c, when the medical practitioner applies a pressing force to the lower side in the height direction on the bed 20, the lift portion 13b gradually eases downward in the height direction. descend slowly. In this way, the medical practitioner moves the bed 20 up and down in a state in which the lift portion 13b is unlocked, and operates the lift lever 13c to lock the lift portion 13b again when the bed 20 reaches an appropriate height position, thereby enabling the bed 20 to be locked. The height position is set at the desired position.

The tilt mechanism 14 supports the bed 20 so as to be tiltable about an axis extending in the left-right direction. More specifically, the tilt mechanism 14 is a mechanism that changes the posture of the bed 20 between the state where the bed 20 is parallel to the installation surface S (see FIG. 2 ) and the state where the front portion of the bed 20 is inclined downward with respect to the installation surface S .

The tilting mechanism 14 includes a tilting connection portion 14a that enables the bed 20 to be tiltably connected to the upper end portion of the lift portion 13b around an axis extending in the left-right direction, and a support fitting 14b that is connected from the tilting connection portion. 14a extends to the lower side in the height direction; a buffer 14c is connected between the lower end of the support fitting 14b and the lower part of the front side of the bed 20 and expands and contracts in accordance with the tilting action of the bed 20; and a tilting lever 14d, the tilt lever 14d allows and restricts the expansion and contraction of the buffer 14c.

The tilting connection portion 14a is configured to change the inclined posture of the bed 20 between a state in which the bed 20 is parallel to the installation surface S and a state in which the front portion of the bed 20 is inclined downward with respect to the installation surface S, while the rear portion of the bed 20 is configured to change. Not sloping down. As the shock absorber 14c, for example, a structure including a gas spring or the like can be employed. One end of the shock absorber 14c is rotatably coupled to the lower end of the support fitting 14b, and the other end of the shock absorber 14c is rotatably coupled to the lower part on the front side of the bed 20.

The tilt lever 14d is provided on both the left side and the right side at a position just below the front part of the bed 20 . Both the tilting operation levers 14d are connected to the shock absorber 14c, and the expansion and contraction of the shock absorber 14c (that is, the tilting of the bed 20) is prohibited (locked) in a state where both tilting operation levers 14d are not operated. That is, the bed 20 maintains a parallel posture with respect to the installation surface S in a state where the tilt operation lever 14d is not operated.

On the other hand, when the lock of the shock absorber 14c is released by the operation of at least one of the tilting operation levers 14d, the shock absorber 14c is in a state capable of expanding and contracting. In this way, when the medical practitioner applies a pressing force to the lower side in the height direction on the front portion of the bed 20 in a state where the shock absorber 14c can expand and contract, the shock absorber 14c is compressed, and the front portion of the bed 20 is inclined downward. In this way, the medical practitioner tilts the bed 20 in a state where the lock of the shock absorber 14c is released, and when the bed 20 reaches an appropriate tilt angle, the shock absorber 14c can be locked again by the operation of the tilt operation lever 14d. The inclination angle of 20 is set to a desired angle.

As shown in FIG. 7, the upper part of the 1st right bearing part 22a of the front frame 22 is provided with the surface (opposing surface) 22a5 which opposes the front-end surface 26a1 of the 1st board|substrate 26a in the state which the 1st rotary gate 26 stood up. The first lock pin 27a is urged to the rear side in the front-rear direction by a spring (not shown) such as a spring such that its distal end portion protrudes from the opposing surface 22a5 of the first right bearing portion 22a. Therefore, as shown in FIGS. 4 and 7 , in a state where the first rotary gate 26 falls to the right in the left-right direction (that is, in a state where the tip portion of the first lock pin 27 a is not blocked), the first lock pin The distal end portion of 27a protrudes from the opposing surface 22a5 of the first right bearing portion 22a.

On the other hand, as shown in FIG. 5 , a locking hole 26a2 is provided in the front end surface 26a1 of the first base plate 26a of the first rotary gate 26, and the locking hole 26a2 is located in the first rotary gate 26 in a state where the first rotary gate 26 is erected. The lock pin 27a is formed to extend on the rear side in the front-rear direction on the movement axis of the lock pin 27a.

In the process of rotating and standing the first rotary gate 26 around the axis extending in the front-rear direction, when the front end portion 26a3 (see FIG. 7 ) of the first base plate 26a comes into contact with the front end portion of the first lock pin 27a, the The rotational force of the one turnstile 26 applies a pressing force toward the front side in the front-rear direction to the first lock pin 27a, and as a result, the first lock pin 27a moves to the front side in the front-rear direction.

In addition, in a state where the first rotary gate 26 is further rotated to stand up, the locking hole 26a2 of the first base plate 26a is located on the moving axis of the first locking pin 27a (ie, does not block the tip portion of the first locking pin 27a). , the first lock pin 27a is moved to the rear side in the front-rear direction again by the force of the spring, and is inserted into the lock hole 26a2.

As a result, the rotation of the first turnstile 26 is restricted (locked) by the first lock pin 27a in the upright state.

As shown in FIG. 7 , the first unlocking operation portion 27b includes an L-shaped operation plate 27b1 slidably connected to the upper surface 22a1 of the first right bearing portion 22a in the front-rear direction, and an operation handle 27b2 , the operation handle 27b2 is provided on the operation panel 27b1 movably in the height direction, and restricts or allows the sliding of the operation panel 27b1.

A pin (not shown) extending downward is provided at the lower end of the operating handle 27b2, and in the initial state, the pin serves as a stopper, and the operating plate 27b1 is in a state where it cannot slide.

As shown in FIG. 9 , when the operation handle 27b2 is lifted upward in the height direction by a medical practitioner or the like, the pins are deviated from the movement axis of the operation panel 27b1, and the operation panel 27b1 becomes slidable. Then, as shown in FIG. 10 , when a medical practitioner or the like slides the operation panel 27b1 to the front side in the front-rear direction, the first lock pin 27a is forced by the first lock pin forcible movement mechanism in conjunction with the sliding operation of the operation panel 27b1. The lock of the first turnstile 26 is released by moving it to the front side in the front-rear direction.

When the first lock pin 27a returns to the initial state position after the lock of the first turnstile 26 is released, the operation panel 27b1 also automatically returns to the initial state position in conjunction with the first lock pin 27a.

In this way, the medical practitioner can release the lock of the first turnstile 26 by performing two-stage operations of the lifting operation of the operation handle 27b2 and the sliding operation of the operation panel 27b1. Therefore, the medical practitioner does not release the lock of the first turnstile 26 by touching the first lock releasing operation portion 27b only slightly, and the medical practitioner can prevent the medical practitioner from releasing the lock of the first turnstile 26 at an unexpected time.

The second rotating grille 28 is a roll-off prevention grille that is rotatably connected between the first left bearing portion 22b of the front frame 22 and the second left bearing portion 23b of the rear frame 23 about an axis extending in the front-rear direction.

The structure of the second turnstile 28 is the same as that of the first turnstile 26 . The connection structure between the second turnstile 28 and the first left bearing portion 22b of the front frame 22 is the same as the connection structure between the first turnstile 26 and the second right bearing portion 23a of the rear frame 23 (see FIG. 8 ). The connection structure of the second turnstile 28 and the second left bearing portion 23b of the rear frame 23 is the same as the connection structure of the first turnstile 26 and the first right bearing portion 22a of the front frame 22 (see FIG. 7 ).

Therefore, the structure of the second turnstile 28 , the connection structure of the second turnstile 28 and the first left bearing portion 22 b of the front frame 22 , and the connection structure of the second turnstile 28 and the second left bearing portion 23 b of the rear frame 23 are omitted. instruction of.

In operation, the lock of the second turnstile 28 is released. Therefore, even if a child patient accidentally (or intentionally) touches the first lock releasing operation portion 27b or the second lock releasing operation portion 29b, the lock of the first turnstile 26 or the second turnstile 28 is not easily released.

However, if a child patient keeps touching the first lock release operation portion 27b or the second lock release operation portion 29b purely out of interest, the lock of the first turnstile 26 or the second turnstile 28 may be unintentionally released. Therefore, in the child bed 1 of the present embodiment, in order to prevent a child patient lying on the bed portion 21 from releasing (operating) the first lock releasing operation portion 27b and the second lock releasing operation portion 29b, the bed 20 further includes: The first partition plate 30 provided between the bed portion 21 and the first lock release operation portion 27b; and the second partition plate 40 erected between the bed portion 21 and the second lock release operation portion 29b. These first separators 30 and second separators 40 correspond to hindering means in the present invention.

Hereinafter, the first separator 30 will be described in detail with reference to FIGS. 7 and 11 to 13 .

FIG. 11 is a perspective view showing the overall structure of the first separator 30 . FIG. 12 is a perspective view of the region shown in FIG. 7 viewed from another direction. In addition, FIG. 12 shows the state which removed the 1st fixed grille 24 from the bed 20. As shown in FIG. FIG. 13 is a plan view of the region shown in FIG. 7 .

The first partition plate 30 is fixed to the first right bearing portion 22a of the front frame 22 so as to stand up between the bed portion 21 and the first lock release operation portion 27b. The first separator 30 is formed in an L-shape in plan view. The first partition plate 30 has a first wall portion 31 having a length in the front-rear direction longer than that of the first lock releasing operation portion 27b and a height higher than that of the first lock releasing operation portion 27b (in this case is the height of the operating handle 27b2) high; the second wall portion 32 upright with respect to the upper surface 22a1 of the first right bearing portion 22a protruding from the first wall portion 31 in the left-right direction; and the third wall The third wall portion 33 connects between the first wall portion 31 and the second wall portion 32 in the left-right direction.

In addition, by using the notch 36 , the wire can be easily inserted into the wire insertion hole 35 . Here, the first separator 30 is preferably formed of an elastic material such as rubber. Since the first separator 30 is formed of an elastic material, the peripheral portion of the cutout 36 is elastically deformed, so that the wire is more easily inserted into the wire insertion hole 35 through the cutout 36 .

That is, even when a wire having a diameter larger than the width dimension of the notch 36 is passed through, the expansion by elastic deformation of the deformed portion forming the notch 36 and the recovery of the deformed portion after passing the wire (width dimension) are utilized. narrowed) to allow the wire to pass easily. More specifically, when the wire to be passed is pressed against the notch 36 , the deformed portion pressed by the wire deforms elastically, and the width dimension of the notch 36 is temporarily enlarged. Then, after the wire passes through the notch 36, the deformed portion returns to its original shape from the elastically deformed state. As a result, since the width dimension of the notch 36 is narrower than the diameter dimension of the wire, the wire is held in a state where the wire stays in the wire insertion hole 35 .

The second partition 40 is fixed to the second left bearing portion 23b of the rear frame 23 so as to stand up between the bed portion 21 and the second lock release operation portion 29b.
