The present invention relates to a portable handrail device placed, for example, next to a bed.

As portable handrail devices, for example, those disclosed in Patent Documents 1 and 2 are known.

The handrail device shown in Patent Document 1 has a handrail portion having a substantially ladder-like shape erected near one edge of the short side of a base having a substantially rectangular planar shape and substantially parallel to the one side edge. It consists of For example, as shown in FIG. 5, this handrail device is mounted in such a direction that the long side edge of the base extends substantially parallel to the long side edge of the bed. When a person stands up from a position sitting on the edge of the bed, or moves from the front of the bed to the side of the bed and sits down on the edge of the bed, the handrail can be grasped.

By the way, when these conventional handrail devices have a structure in which the handrail portion is arranged near one side edge of the base having a substantially rectangular planar shape and substantially parallel to the one side edge, for example, the handrail portion If a person is located on the opposite side, the entire handrail portion will be at a uniform distance from the person. Therefore, for example, when a person takes a posture of moving from the current posture of facing the handrail to another location in front of the right while changing the direction of the body to the right, the left hand side is facing the handrail. This makes it difficult to grasp the handrail.

Conversely, for example, when a person is in a posture with their body direction approximately parallel to the direction in which the handrail extends, that is, the handrail is positioned approximately parallel to the body direction on the right or left hand side of the person. In this case, the distance between the handrail and the person increases from the front side of the handrail toward the front. For this reason, for example, the side where the person moves away from the handrail from the current posture (i.e., the left side if the handrail is located on the right side of the person, and the left side if the handrail is located on the left side of the person) When a person takes a posture of moving to the right while changing the body direction, the front part of the handrail gradually moves away from the person, making it difficult to grasp the handrail.

Under these circumstances, there is a need to develop handrail devices that can always achieve good grip regardless of changes in the relative relationship with people, but at present no effective proposals have been made from this perspective. do not have.

Therefore, the present invention has been made with the object of providing a handrail device that can always achieve good gripping performance regardless of changes in the relative relationship with a person.

The present invention employs the following configuration as a specific means for solving this problem.

In a first aspect of the present application, there is provided a pedestal having a substantially rectangular planar shape, the pedestal having a short side edge placed substantially parallel to one side edge of the bed; In a handrail device comprising a handrail unit having a first fixed leg and a second fixed leg that are erected and fixed apart from each other at a position near one side edge of a pedestal, the handrail unit has a first fixed leg and a second fixed leg. An axis along a straight line connecting the center of the first fixed leg and the center of the second fixed leg is directed from one end side of the one side edge of the pedestal near the first fixed leg to the other end side near the second fixed leg. The portable toilet or wheelchair is fixed at a predetermined angle of inclination from one side edge of the pedestal toward the opposite side edge of the pedestal. It is characterized by being arranged substantially parallel to one edge of the long side.

In a second aspect of the present invention, in the handrail device according to the first aspect, the inclination angle of the handrail unit is in a range of 6° to 30°.

In the third invention of the present application, in the handrail device according to the first or second invention, the handrail unit has the axis line on the upper end side of the first column supported by the first fixed leg in a side view. A first gripping portion extending in the direction is provided, and a second gripping portion bent in a substantially U-shape is provided on the upper end side of the second column supported by the second fixed leg. It is also characterized in that it is provided on the upper side and extends further forward in the axial direction than the second support column.

The present invention provides the following effects.

(a) First invention of the present application According to the handrail device according to the first invention of the present application, the handrail unit is connected to a straight line connecting the center of the first fixed leg and the center of the second fixed leg in a plan view. An axis along the pedestal extends from one end of the pedestal near the first fixed leg to the other end of the pedestal near the second fixed leg. The portable toilet or wheelchair is fixed at a predetermined angle of inclination toward the inside of the pedestal so that the front edge of the portable toilet or wheelchair is disposed approximately parallel to one long side edge of the pedestal. , the other side edge of the pedestal adjacent to the one side edge where the handrail unit is arranged, and the distance from the side edge closer to the first column to the second column, or the other side opposite to the one side edge. The distance from the edge to the second support column is shorter than, for example, when the handrail unit is fixed in a direction parallel to the side edge of the pedestal, as in the conventional case. Therefore, for example, the gripping action is easy whether the handrail unit is grabbed from the other side edge adjacent to the one side edge or the handrail unit is grabbed from the other side edge opposite to the one side edge. As a result, the assistance function of the handrail device for people is improved.

In particular, when there is a person on the other side edge adjacent to the one side edge, the handrail unit will be located on the person's right hand side. For this reason, for example, if the handrail unit is arranged parallel to one side edge of the pedestal as in the past, when a person tries to grasp each gripping part of the handrail unit with his/her right hand, he or she will naturally have to use the right arm. Since the user takes a posture that opens to the right side rather than the front of the body, and the back of the hand faces toward the gripping portion, it becomes difficult to grip the first gripping portion. However, when the handrail unit is tilted toward the center of the pedestal as in the present invention, when grasping the grip portion of the handrail unit with the right hand, the right arm is tilted toward the center of the body rather than in front of the body. Since the gripping portion can be gripped from the palm side, the ability to grip the gripping portion is improved, and the assistance performance of the handrail device is improved.

(b) Second invention of the present application According to the handrail device according to the second invention of the present application, since the inclination angle of the handrail unit is in the range of 6° to 30°, the handrail unit is attached to the pedestal. It is possible to shorten the distance to the handrail unit from both the first part side and the second part side without extending it excessively toward the center, thereby increasing the gripability of the handrail unit, and the above (a) ) will be more certain.

(c) Third invention of the present application According to the handrail device according to the third invention of the present application, in addition to the effects described in (a) or (b) above, the following unique effects can be obtained. That is, in the handrail device of the present invention, in the side view of the handrail unit, the first gripping portion extending in the axial direction is provided on the upper end side of the first column supported by the first fixed leg; On the upper end side of the second column supported by the second fixed leg, a second gripping portion bent in a substantially U-shape is provided above the first gripping portion and above the second column. It is provided so as to extend toward the front side in the axial direction.

Therefore, a first empty space is provided above the first gripping portion and in front of the second gripping portion, and a first empty space is provided below the second gripping portion and in front of the second support column. 2 empty spaces will be formed respectively. The existence of the first empty space prevents the arm from hitting the handrail unit when the arm is extended from the rear side of the first support to grasp the first gripping part or the second gripping part. , Accurate grasping motion is ensured, and the presence of the second empty space prevents the person's legs from hitting the handrail unit during the motion of grasping the first grasping part or the second grasping part, thereby improving body movement. Since the degree of freedom is increased, further improvement of the assistance function of the handrail device can be expected as a synergistic effect of these effects.

1 to 4 show a handrail device Z according to an embodiment of the present invention. This handrail device Z includes a pedestal 1 and a handrail unit 2, as described below.

A: Configuration of pedestal 1 The pedestal 1 is a substantially flat plate having a rectangular planar shape, and is placed on a floor surface. A first fixed leg 3 and a second fixed leg 4 made of a straight tube body for attaching a handrail unit 2 to be described below are installed in an upright state near one edge 1a on the short side of this pedestal 1. There is. In this case, the first fixed leg 3 and the second fixed leg 4 are not arranged in parallel to one side edge 1a of the pedestal 1, but rather It is installed in an inclined position. That is, as shown in FIG. 4, among the first fixed leg 3 and the second fixed leg 4, the first fixed leg 3 has the one side edge 1a and the one side edge 1c on the long side adjacent thereto. The lower end 3a is fixed to the pedestal 1 near the corner of the pedestal 1, so that it is erected here. On the other hand, the second fixed leg 4 is rotated by an angle of 18 degrees toward the center of the pedestal ₁ from a straight line L0 that passes through the center of the fixed portion of the first fixed leg 3 and extends parallel to the one side edge 1a. It is erected here by fixing its lower end portion 4a at a position on the straight line _L2 and a distance S apart from the position of the first fixed leg 3.

In this embodiment, the first fixed leg 3 and the second fixed leg 4 are attached on the straight line _L2 , but the present invention is not limited to this, and it is possible to achieve the intended purpose. As the achievable angle range, we assume an angular range from straight line _L1 , which is inclined at an angle of 6 degrees from the above-mentioned straight line _L0 , to straight line _L3 , which is inclined at an angle of 30 degrees, and at any angular position within this angle range. The first fixed leg 3 and the second fixed leg 4 can be erected. Note that the critical significance of the minimum angle and maximum angle in this angular range will be described later.

B: Configuration of handrail unit 2 The handrail unit 2 includes a first support 5 supported by the first fixed leg 3 on the pedestal 1 side, a second support 6 supported by the second fixed leg 4, and the second support support 6 supported by the second fixed leg 4. It is comprised of a U-shaped rod 7 connected to the upper part of two columns 6, and a J-shaped rod 8 connected to the lower side of the U-shaped rod 7.

The first support column 5 is formed by bending a tubular body of a predetermined diameter into a substantially L shape, and the first support column 5 is fixed by inserting its lower end 5a into the first fixing leg 3 from its upper end 3b side. It is fixed to the leg 3 side. The upper end 5b of the first support 5 extends substantially horizontally, and the end 5c thereof is connected and fixed to the upper end 6b of a second support 6, which will be described below, and is integrated with the second support 6. There is. Note that this horizontally extending upper end portion 5b is referred to as a “first grip portion 11” in the claims.

The second support column 6 is a straight tube with a predetermined diameter, and is fixed to the second fixed leg 4 by inserting its lower end 6a into the second fixed leg 4 from its upper end 4b. There is. Further, in this case, the distance S (see FIG. 4) between the first support column 5 and the second support column 6 is defined and held by the first grip part 11.

The U-shaped rod 7 is formed by bending a tubular body of a predetermined diameter into a U shape, and one end 7a thereof is connected to the upper end 6b side of the second support 6, while the other end 7b is connected to the following J The upper end 8a of the shaped rod 8 is connected. Furthermore, a connecting member 9 is provided at the middle position of the U-shaped rod 7 in the vertical direction to ensure its rigidity. Note that this U-shaped rod 7 is referred to as a "second grip part 12" in the claims.

The J-shaped rod 8 is formed by bending a tubular body of a predetermined diameter into a J-shape, and one end 8a thereof is connected to the other end 7b of the U-shaped rod 7, while the other end 8b is connected to the second support column 6. It is connected to the. A connecting material 10 is provided between the upper end 8a of the J-shaped rod 8 and the second support 6, thereby ensuring the rigidity of the J-shaped rod 8 and the U-shaped rod 7.

As shown in FIG. 4, this handrail unit 2 is formed into a flat frame shape in which all of the above-mentioned components are located on the same vertical plane, and includes the first support 5 and the second support 6. are fitted into and fixed to the first fixed leg 3 and second fixed leg 4 on the pedestal 1 side, respectively, so that the handrail device Z is integrated with the pedestal 1 and constitutes a handrail device Z.

In addition, in this handrail device Z, as shown in FIGS. 1 and 2, a first empty space 15 is formed above the first gripping part 11 and in front of the second gripping part 12, Further, a second empty space 16 is formed below the second gripping part 12 and in front of the second support column 6. As will be described later, these empty spaces 15 and 16 function to enhance gripability when a person grips the first gripping part 11 and the second gripping part 12.

C: Installation example of the handrail device Z In this embodiment, as an example of the installation structure of the handrail device Z, as shown in FIGS. 4, 5, and 6, the long side of the bed 21 installed indoors is In the corner-shaped space formed by the one side edge 21a and the front edge 22a of the portable toilet 22 installed near the one side edge 21a and oriented in a direction parallel to the extending direction thereof. This shows the case where it is installed.

The main purpose of this handrail device Z is to assist the posture and movement of a person when moving between the bed 21 and the portable toilet 22, so when installing it, the handrail unit 2 is The basic idea is to position the handrail unit 2, the bed 21, and the portable toilet 22 on the right side of the right side of the portable toilet 22 to secure a moving space between the handrail unit 2, the bed 21, and the portable toilet 22.

Based on this basic idea, specifically, in the handrail device Z, the side edge 1b on the short side of the pedestal 1 is close to and substantially parallel to one side edge 21a of the bed 21, Further, one long side edge 1c of the pedestal 1 is approximately parallel to the front edge 22a of the portable toilet 22, and the front edge of the leg 22b rests on the one side edge 1c of the pedestal 1. It has become. Note that this is just one installation example, and in other installation examples, for example, the edge 1b on the short side of the pedestal 1 may be inserted into the lower surface of the bed 21, or the edge 1b on the long side of the pedestal 1 may be It goes without saying that changes can be made as appropriate, such as locating one side edge 1c away from and in front of the front edge of the leg 22b of the portable toilet 22.

FIG. 5 shows that when a person is sitting on the seat 22c of the portable toilet 22 and relieving himself, he is holding the second gripping portion 12 of the handrail unit 2 with both hands to maintain his posture. It shows the state of being. Hereinafter, this usage state of the handrail device Z will be referred to as a "first usage state."

FIG. 6 shows a standing state where the body starts to rise from the seat 22c of the portable toilet 22 toward the bed 21 side, or when the portable toilet 22 is moved from the bed 21 side to the portable toilet 22 side and the portable toilet The figure shows a state in which the user begins to lower his or her back while grasping the second gripping portion 12 of the handrail unit 2 with both hands in order to sit on the seat portion 22c of the handrail unit 2. Hereinafter, the usage states of these two handrail devices will be referred to as "second usage states."

D: Effects in the first usage state In the first usage state shown in FIG. However, in this case, since the handrail unit 2 is located in front of the right body of the person 20, for example, the handrail unit 2 is held at one part of the pedestal 1 as in the conventional case. If it extends parallel to the side edge 1a, the distance to the gripping position becomes long especially for the left hand that grips the front side of the second gripping portion 12, so the left arm must be stretched out to grip the second gripping portion 12. However, it is difficult to grasp it, and it also requires a twisting motion, which increases the physical burden.

However, in the handrail device Z of this embodiment, as shown in FIG. 4, the handrail unit 2 is connected to a straight line _L2 that is inclined at an angle of 18 degrees toward the center of the side pedestal 1 with respect to one side edge 1a of the pedestal 1. Since it is placed at the top, the front part of the second gripping part 12 approaches the person 20 by an amount corresponding to the inclination of the handrail unit 2, so that the person 20 can easily use the left hand without having to twist his or her body to the right. The front portion of the second gripping portion 12 can be gripped.

Furthermore, the fact that the second gripping part 12 of the handrail unit 2 is located near the center of the pedestal 1 means that the second gripping part 12 is located on the right side of the person 20 seated on the seat 22c of the portable toilet 22. This means that it has moved from the closer position to the front position of the body. Therefore, by moving the second gripping part 12 toward the front of the body, the palm side of the right hand of the person 20 faces the second gripping part 12 instead of the back side of the hand, and the second gripping part 12 gripping becomes easier and more secure.

E: Effects in the second usage state In the second usage state shown in FIG. 6, the person 20 seated on the seat 22c of the portable toilet 22 moves from the portable toilet 22 side to the bed 21 side In order to move, when the user grips the first grip part 11 of the handrail unit 2 with his right hand, he also grips the second grip part 12 with his left hand, with his hips lifted.

In this case, in this embodiment, the handrail unit 2 is on the straight line _L2 , and the second gripping part 12 is larger than the case where the handrail unit 2 is arranged on the pedestal 1 in parallel with the one side edge 1a. Since the user is approaching the person 20, when holding out the left arm diagonally from the front of the body to grip the second gripping portion 12, the second gripping portion 12 can be gripped easily and reliably.

In addition, the person 20 grasps the first gripping part 11 of the handrail unit 2 with his right hand, but in this case, the person 20 holds the first gripping part 11 above the first gripping part 11 and in front of the second gripping part 12. Since the first empty space 15 is formed, when the person 20 grasps the first gripping part 11 with the right hand, interference between the right arm and the handrail unit 2 is reliably prevented. The gripping portion 11 can be gripped easily and reliably, and the gripability is improved.

Further, the person 20 steps forward with both feet in preparation for standing up, but in this case, the second empty space is located below the second gripping section 12 and in front of the second support column 6. 16 is formed, the person 20 can step his or her right foot into the second empty space 16 to position the right foot forward without interfering with the handrail unit 2. As a result, getting up from the portable toilet 22 becomes easier and safety is ensured.

On the other hand, although not shown, in the second usage state, the person 20 moves from the bed 21 side to the portable toilet 22 side and moves to sit on the seat 22c of the portable toilet 22. However, in this case, after the person 20 stands up from the bed 2, the direction of the front of the person's body inevitably changes to the right side in order to head toward the portable toilet 22 located in front of the person's right hand. As a result, the left hand also changes to the right side from the position in front of the body. As a result, for example, when the handrail unit 2 is parallel to one side edge 1a of the pedestal 1 as in the conventional case, the left hand moves away from the second gripping part 12 of the handrail unit 2, and this It becomes difficult to grasp. However, in this embodiment, the handrail unit 2 is arranged to be inclined closer to the center than the one side edge 1a of the pedestal 1, so the distance between the second grip part 12 and the left hand is shortened. , the person 20 can accurately grasp the second gripping part 12 with his/her left hand.

F: Critical significance of the mounting angle of the handrail unit 2 to the pedestal 1 In the present invention, as described above, the mounting angle of the handrail unit 2 to the pedestal 1 is set from the direction of one side edge 1a of the pedestal 1. It is set in the range of a position inclined at an angle of 6° toward the center of the pedestal 1 (position of straight line _L1 in Fig. 4) and a position inclined at an angle of 30° (position of straight line _L3 in Fig. 4). .

Here, the minimum angle "6°" of the above angle range is set as the limit angle at which the effect of moving the second gripping part 12 of the handrail unit 2 toward the center of the pedestal 1 can be obtained. , On the lower angle side (i.e., the side closer to one side edge 1a of the pedestal 1 in the direction), the above effect becomes smaller and you can hardly feel the effect, so the above "angle 6°" is set as the limit angle. This is what I did.

On the other hand, the maximum angle "30°" in the above angle range is to prevent the corner of the space on the upper surface side of the pedestal 1 from being narrowed by the second support 6 located on the front side of the handrail unit 2, and to This setting was made by comparing and considering the effect of moving the two gripping parts 12 closer to the center of the base 1. That is, the larger the attachment angle of the handrail unit 2 to the pedestal 1 is, the more the second gripping part 12 is displaced toward the center of the pedestal 1. It can be said that the larger the value, the better. However, the fact that this angle becomes larger means that the second gripping part 12 moves closer to the center of the pedestal 1, and the space on the upper surface side of the pedestal 1 (that is, the movement space for the person 20) becomes narrower. This results in an unfavorable situation in terms of the mobility of the person 20.

Therefore, by arranging the handrail unit 2 at an angle, it is possible to improve the grip on the second gripping part 12, and because the handrail unit 2 is moved closer to the center of the pedestal 1, the space on the pedestal 1 side is reduced. The above-mentioned "angle of 30°" was set as an angle that can satisfy the conflicting demands of ensuring the gripability of the second gripping part 12 and securing the space on the pedestal 1 side. .

In addition, in this embodiment, the above-mentioned bed 21 and portable toilet 22 have been explained as examples of equipment for using the above-mentioned handrail device Z, but in addition to these, for example, a wheelchair may be provided in place of the above-mentioned portable toilet 22. You can also do it.

The handrail device according to the present invention can be widely used mainly in the nursing care field.
