JP7553012B2 - Opening and closing fence and bed equipped with opening and closing fence - Google Patents

Description

The present invention relates to an opening and closing fence that is installed on the side of a bed, which is suitable for nursing care, etc.

Some nursing care beds used in hospitals, nursing facilities, or homes have horizontally rotating opening and closing bars on the sides of the bed (see, for example, Patent Documents 1 to 3).

The opening and closing fence functions as a handrail to assist the user when moving from inside the bed to outside the bed, and when moving from outside the bed to inside the bed.

The opening and closing fences in Patent Documents 1 to 3 use the horizontal rod-shaped portion located at the top as the handrail (see the horizontal rod-shaped portion at the top of the rotating fence 17 in Patent Document 1, the rod-shaped body 10 in Patent Document 2, and the rotating handrail portion 42 in Patent Document 3).

On the other hand, in order to make it easier to identify the position of the bed when the lights are turned off in the dark in the room in which the bed is installed at night, there are some beds in which a phosphorescent fluorescent material is attached to the headboard or footboard (see, for example, phosphorescent fluorescent materials 5, 5' in Figure 1 of Patent Document 4) or fluorescent paint is applied to the headboard or footboard (see, for example, fluorescent paints 1c, 2c in Figure 1 of Patent Document 5).

JP 2006-55529 A Patent No. 4802296 JP 2016-77642 A Utility Model Publication No. 56-13951 Japanese Patent Application Publication No. 8-112166

In particular, if the user of the bed is a sick or elderly person with a physical disability and the user goes to the toilet many times during the night, the opening and closing fence, which functions as a handrail to assist the user's movement, needs to be reliably visible to the user even at night.

In other words, the opening and closing fence needs to be easily visible in a dark room at night when the user moves from inside the bed to outside the bed, when the user moves from outside the bed to inside the bed, or when the user falls out of the bed or hits the floor when returning to the bed.

In addition, if the user falls off the bed or lands on the floor when returning to bed, the opening and closing fence must be easy for the user to grab hold of.

The present invention aims to provide a fence that is easy to see in a dark room at night, and that is easy for the user to grasp as a handhold.

The gist of the present invention is as follows:

[1]
A horizontally rotating opening/closing fence is provided on the side of the bed,
The opening and closing fence is opened in the forward direction, and linear light-accumulating bodies are provided on the front and rear surfaces of a horizontal rod-shaped body that is a member forming the opening and closing fence, and the linear light-accumulating bodies are provided along the longitudinal direction of the horizontal rod-shaped body ,
The horizontal rod-shaped body is provided in a plurality of pieces spaced apart in the vertical direction,
The light-storing body is provided in a horizontal groove formed in the uppermost horizontal rod-shaped body,
the horizontal groove is provided between the top of the horizontal bar-shaped body in a cross section and a horizontal end of the cross section so as to open obliquely upward;
The thickness of the phosphorescent body is smaller than the depth of the horizontal groove .
Opening and closing fence.

[ 2 ]
The opening and closing fence is a ladder-like shape having four or more horizontal rods spaced apart in the vertical direction.
The opening and closing fence described in [1].

[ 3 ]
A bed equipped with an opening and closing fence as described in [1] or [ 2 ].

The opening and closing fence of the present invention has linear phosphorescent bodies arranged along the longitudinal direction of a horizontal rod-shaped body on the front and rear surfaces of the horizontal rod-shaped body that is the member that forms the opening and closing fence, with the direction in which the opening and closing fence is opened being the front.

As a result, in a dark room at night, the horizontal linear phosphorescent body emits light on the front and rear of the horizontal rod-shaped body. Therefore, in a dark room at night, the bed user and other caregivers can visually recognize the light emitted by the phosphorescent body and determine the position of the opening and closing fence, thereby increasing safety.

In addition, the fence, which functions as a handrail to assist the user when moving from inside the bed to outside the bed and from outside the bed to inside the bed, allows the user to easily see whether the fence is open or closed, even in a dark room at night, and the position of the fence can be easily seen. This improves safety when the user goes to the toilet multiple times at night. Furthermore, because the open/closed state and position of the fence are easily visible, even in a dark room at night, the fence can be easily used as a handhold when the user falls off the bed or hits the floor when returning to the bed.

The following describes an embodiment of the present invention with reference to the drawings.

The bed B of the present invention is substantially rectangular in plan view, and in this specification, the direction parallel to the long side of the rectangle is referred to as the "bed longitudinal direction." In addition, in this specification, the front view of bed B is a view of the user lying on his/her back as seen from the right side of the user.

The bed B according to the embodiment of the present invention is an electric bed 1. The electric bed 1 is, for example, a three-motor bed, and can adjust the height as well as raise the back and knees. The bed B provided with the opening and closing fence A according to the present invention is not limited to the electric bed 1. The opening and closing fence A according to the present invention may be provided on the side S of a non-electric bed B.

In the following embodiment, an example of the opening and closing fence A provided on the side S of the bed B of the present invention is shown, in which the opening and closing fence A is attached to the side fence 8. The opening and closing fence A of the present invention may be attached independently to the frame body (e.g., the lifting frame 3) without being attached to the side fence 8, or may be supported by the base unit 2 of the bed B, etc.

<Bed>
As shown in the oblique view of Figure 1 and the front view of Figure 2, an electric bed 1, which is a bed B according to an embodiment of the present invention, comprises as its main components a base unit 2, a lifting frame 3 which is the frame main body, a bottom 4, a headboard 5, a footboard 6, side rails 8 and an opening and closing rail A.

The base unit 2 is placed on the floor, and the lifting frame 3 is connected to the base unit 2 so that it can be raised and lowered. The bottom 4 is attached to the upper surface of the lifting frame 3, and the headboard 5 and footboard 6 are attached to both ends of the lifting frame 3 in the longitudinal direction of the bed.

The bottom 4 includes a back bottom 4A, a seat bottom 4B, a knee bottom 4C, and a leg bottom 4D. The back bottom 4A is positioned to support the user's head and back, the seat bottom 4B is positioned to support the user's waist, the knee bottom 4C is positioned to support the user's knees, and the leg bottom 4D is positioned to support the user's legs.

A user of the electric bed 1 places a mattress (not shown) on the top surface of the bottom 4 and lies down on the mattress with the head facing the headboard 5 and the feet facing the footboard 6.

The side rails 8 are supported by option brackets 7, 7 provided on the side frames of the lifting frame 3, and the opening and closing rail A is supported by the side rails 8 so that it can rotate horizontally. The side rails 8 and the opening and closing rails A are located on the side S of the electric bed 1.

As shown in the perspective view of Figure 3, which shows the base unit 2 and lifting frame 3, the option receivers 7, 7 have holes 7A, 7A. By fitting the engagement pins 8A, 8B shown in the perspective view of Figure 4, which shows the side fence and opening/closing fence, into the holes 7A, 7A, the side fence 8 is attached to the lifting frame 3, as shown in the perspective view of Figure 1 and the front view of Figure 2.

<Opening and closing fence>
The perspective view of Fig. 4 shows a closed state C in which the opening and closing fence A is closed, and the perspective view of Fig. 5 shows an open state D in which the opening and closing fence A is open. The opening and closing fence A is supported by the side fence 8 via connecting parts 9A and 9B, and rotates horizontally about the connecting parts 9A and 9B. That is, the opening and closing fence A rotates horizontally between the closed state C in Fig. 4 and the open state D in Fig. 5 by releasing the locked state with the lock lever 10.

When the lock lever 10 is used to lock the fence in the closed state C in FIG. 4, the fence A is fixed in the closed state C position. When the lock lever 10 is used to lock the fence in the open state D in FIG. 5, the fence A is fixed in the open state D position.

The opening and closing fence A has a horizontal rod row 11 and a vertical rod row 12.

The horizontal rod row 11 is composed of four horizontal rods 11A, 11B, 11C, and 11D spaced apart in the vertical direction. The horizontal rod row 11 may also be composed of two or three horizontal rods spaced apart in the vertical direction, or five or more horizontal rods spaced apart in the vertical direction. In other words, the horizontal rod row 11 may be composed of multiple horizontal rods spaced apart in the vertical direction.

The vertical rod row 12 is composed of three vertical rods 12A, 12B, and 12C spaced apart in the horizontal direction. The vertical rod row 12 may also be composed of two vertical rods spaced apart in the horizontal direction, or four or more vertical rods spaced apart in the horizontal direction. In other words, the vertical rod row 12 may be composed of multiple vertical rods spaced apart in the horizontal direction.

The opening and closing fence A is preferably formed in a ladder shape to provide an easy-to-grasp handhold. Therefore, it is preferable that the horizontal rod row 11 is made up of four or more horizontal rods spaced apart in the vertical direction.

The opening and closing fence A in the above-mentioned form is made of thermoplastic resin and is manufactured by blow molding to be hollow, with an easy-to-grip diameter of about 3 cm to 4 cm, and to have the required strength and rigidity. By manufacturing the opening and closing fence A by blow molding, the number of parts can be reduced and the weight can be reduced.

As shown in the perspective views of the opening and closing fence A in Fig. 4 and Fig. 5, and the cross-sectional view of the horizontal rod in Fig. 6, the horizontal rod 11A located at the top of the horizontal rod row 11 that forms the opening and closing fence A has linear phosphorescent bodies L on the front face F and rear face G along the longitudinal direction H of the horizontal rod 11A, with the front being the direction E in which the opening and closing fence A is opened. The phosphorescent bodies L are, for example, phosphorescent tape, but may also be phosphorescent paint or the like. The width of the phosphorescent bodies L is about 2 to 4 mm, the length of the phosphorescent bodies L is about 250 to 350 mm, and the thickness of the phosphorescent bodies L is about 0.3 to 0.5 mm.

The phosphorescent body L is provided in horizontal grooves 13 formed on the front surface F of the horizontal rod-shaped body 11A, and in horizontal grooves 14 formed on the rear surface G of the horizontal rod-shaped body 11A. The "line" of the linear phosphorescent body L means, for example, a continuous straight line, but it may also be a discontinuous line such as a dashed line or a dashed dotted line. The width of the horizontal grooves 13, 14 is about 4 to 8 mm, the length of the horizontal grooves 13, 14 is slightly longer than the length of the phosphorescent body L to match the length of the phosphorescent body L, and the depth of the horizontal grooves 13, 14 is, for example, about 1 to 2 mm.

The phosphorescent body L stores light from sunlight, fluorescent lamps, etc. that is irradiated onto the phosphorescent body L, and emits the stored light in a dark place.

The phosphorescent material L may be provided on a horizontal rod 11A other than the topmost one in the horizontal rod row 11. That is, for example, in the opening and closing fence A in Figures 2, 4, and 5, the phosphorescent material L may be provided on horizontal rods 11B, 11C, or 11D. Alternatively, the phosphorescent material L may be provided on multiple horizontal rods (e.g., two of the four horizontal rods) that form the horizontal rod row 11.

The cross-sectional view of the horizontal rod in Figure 7 shows modified horizontal grooves 13, 14 and phosphorescent material L. In the example of Figure 7, horizontal grooves 13, 14 are provided between the top a of the cross section of the top horizontal rod 11A and the horizontal ends b, c of said cross section (horizontal end b is the foremost part of the front surface F of the horizontal rod 11A, and horizontal end c is the rearmost part of the rear surface G of the horizontal rod 11A) so as to open diagonally upward. Then, linear phosphorescent material L is provided within the horizontal grooves 13, 14 along the longitudinal direction H (Figures 2, 4 and 5) of the horizontal rod 11A.

By locating the linear phosphorescent body L on the rear surface G of the horizontal rod-shaped body 11A on the user side of bed B (Figs. 1 and 2) in a horizontal groove 14 that opens diagonally upward and is provided between the top a of the cross section of the uppermost horizontal rod-shaped body 11A and the horizontal end c of said cross section, the light emitted by the phosphorescent body L is unlikely to be an eyesore when the user of bed B (Figs. 1 and 2) is lying down, and will not disturb the user's sleep.

By locating the linear phosphorescent body L on the front face F of the horizontal rod-shaped body 11A on the side opposite the user of bed B (Figs. 1 and 2) in a horizontal groove 13 that opens diagonally upward and is provided between the top a of the cross section of the uppermost horizontal rod-shaped body 11A and the horizontal end b of said cross section, the light emitted by the phosphorescent body L is unlikely to be an eyesore to the user of the bed, and will not disturb the user's sleep, even if there is another bed in the same room and the user of that bed is sleeping.

When the user of bed B (Figs. 1 and 2) moves out of bed B, for example, the user can raise his/her upper body to raise his/her viewpoint, making it easier to see the light emitted by the phosphorescent body L in the horizontal groove 14 that opens diagonally upward on the user's side of bed B (Figs. 1 and 2).

As described above, the opening and closing fence A according to the embodiment of the present invention has linear phosphorescent bodies L arranged along the longitudinal direction H of the horizontal rod body 11A on the front surface F and rear surface G of the horizontal rod body 11A, which is a member that forms the opening and closing fence A, with the direction E in which the opening and closing fence A is opened being the front.

As a result, in a dark room at night, the horizontal linear phosphorescent body L emits light on the front surface F and rear surface G of the horizontal rod-shaped body 11A. Therefore, in a dark room at night, the user of the bed B and other caregivers can visually recognize the emission of the phosphorescent body L and locate the position of the opening and closing fence A, thereby improving safety.

Furthermore, when the user moves from inside bed B to outside bed B and from outside bed B to inside bed B, the opening and closing fence A functions as a handrail to assist the user's movement, and even in a dark room at night, the opening and closing state of the opening and closing fence A, whether it is in the closed state C (Figs. 1, 2, 4) or the open state D (Fig. 5), can be easily seen, and the position of the opening and closing fence A can be easily seen. Therefore, safety can be improved when the user goes to the toilet multiple times at night, etc.

Furthermore, even in a dark room at night, the open/closed state of the opening/closing fence A and its position are easily visible, so that the opening/closing fence A can be easily used as a clue when the user falls off bed B or lands on the floor when returning to bed B. In particular, if the opening/closing fence A is ladder-shaped with four or more horizontal bars, the user can select and grasp a horizontal bar of the ladder-shaped opening/closing fence A at an easy-to-grasp height, or a part of the vertical bar at an easy-to-grasp height between the upper and lower horizontal bars, regardless of the user's physique or posture. This allows the user to stand up from the floor and return to bed, using the part of the opening/closing fence A that the user has selected and grasped that is easy for the user to grasp and exert force on as support.

The above description of the embodiments is merely illustrative and is not intended to be limiting. Various improvements and modifications may be made without departing from the scope of the present invention.
