Description

    The present invention relates to a toilet bowl that can be used without assistance from a caregiver by an elderly person or a physically handicapped person with reduced physical ability, and is an invention related to a toilet bowl that is easy to transport and move.

So-called portable toilets that can be easily transported and moved in living rooms, hospital rooms or bedrooms are used for disabled persons with disabilities and elderly people with reduced physical abilities when walking to the toilet is difficult. .
Various types of portable toilets have been proposed. For example, a handrail is provided on both sides in the front-rear direction and can be safely operated by being seated on the toilet seat or grasping when standing, and can support the body in the toilet (for example, Patent Document 1). reference.).

  In this example, a handrail frame, which is integrated with a handrail, a backrest, and the like, is provided on a portable toilet so that the user can use it safely without the assistance of a caregiver. However, this handrail frame is a separate body from the portable toilet. When moving the portable toilet, it is necessary to install a handrail frame separately, and the convenience of the portable toilet has been lost.

  In addition, conventional portable toilets mainly consist of toilet seats and buckets that store excrement, and the simple and lightweight type that only stores excrement was the mainstream. With respect to the space, demands for hygiene and comfort are increasing, and there is an increasing demand for the addition of high functions such as a function of washing a butt with warm water and a deodorizing function. Therefore, products with handrails and backrests attached to portable toilets and products with high functionality and heavy type (weight of 10 kg or more) are on the market. On the other hand, when such a portable toilet is transported or moved, it is difficult to simply lift it in the vertical direction, so it has been proposed to add casters and move it with as little force as possible (for example, , See Patent Document 2).

  In addition, with conventional fixed-type handrails, for example, when a user moves from a bed or wheelchair to a portable toilet, the user moves horizontally from a sitting state on a bed or chair or a low posture often seen by elderly people. In this case, the handrail will hinder the transfer operation. Patent Document 2 proposes a handrail attached to a portable toilet, but it is easy to move because of a caster, but it is difficult for a user to transfer because the handrail is fixed to the portable toilet.

It has also been proposed that a user can move to a portable toilet easily by moving at least a part of the handrail so as not to interfere with the transfer operation (e.g., preferably without the assistance of a caregiver). (See Patent Document 3).
In this case, in order to lower the handrail when transferring from the user's bed, wheelchair or the like, the fixing screw portion is loosened, so that there is a risk that the operation takes time and sometimes the finger is pinched when lowered. Also, the posture during use is unstable and inconvenient.

  The present invention solves the above-described problems, and allows a portable toilet to be easily moved. Further, a portable toilet that allows a user to transfer to and use the portable toilet (for stool) without the assistance of a caregiver. provide.

In order to solve the above-mentioned problems, according to the invention of claim 1, a portable toilet having a toilet seat, a caster fixed to a lower rear portion of the portable toilet, and bent and formed at both ends thereof are side surfaces of the portable toilet. A portable toilet with a handrail comprising a handrail fixed to a fixed portion formed at a rear portion, wherein the handrail is mounted on the portable toilet and a position above the rear end of the toilet seat and substantially parallel A horizontal portion formed in the horizontal portion, an inclined portion formed by being bent so as to be inclined downward and forward from both ends of the horizontal portion, and a substantially vertical direction downward from the front end of the inclined portion that is located above the toilet seat. And a pair of vertical portions formed in the vertical direction downward from the curved portion and provided with the mounting portion, and a predetermined distance from the curved portion. A rotation support portion provided at a predetermined position of an inclined portion spaced upward, a position substantially parallel to the toilet seat with respect to the rotation support portion, and a substantially vertical position that opens a side space of the toilet seat And a movable handrail supported so as to be rotatable between the two.
Thereby, a portable toilet can be freely moved as needed by using this handrail and a caster fixed to the portable toilet. In addition, when the movable handrail is substantially parallel to the toilet seat, the user can perform a safe operation by grasping the movable handrail while sitting on the toilet seat or standing, and also supports the body during the toilet. be able to. In addition, when the movable handrail is substantially perpendicular to the toilet seat, it is easy for the user to transfer to the portable toilet, and it can be moved by grabbing the movable handrail and the inclined part to the curved portion. Therefore, transfer can be easily performed without the assistance of a caregiver.

According to a second aspect of the present invention, the movable handrail is inclined to the inside of the toilet seat at a position substantially parallel to the toilet seat, and on the outer side opposite to the toilet seat at a position substantially perpendicular to the toilet seat. It is characterized by rotating between tilted positions.
As a result, at a position where the movable handrail is substantially parallel to the toilet seat, there is a movable handrail along the user's body so that the body can be stabilized during use, and the forward leaning posture that promotes excretion can be easily maintained even for a long time. At the same time, it is easy to put effort into the toilet. In addition, at a position substantially perpendicular to the toilet seat, the movable handrail does not interfere with the portable toilet body by rotating to the position opposite to the toilet seat side, and a user in a sitting position can move the movable handrail. It is easy to perform a grabbing operation for lowering to a substantially parallel position, and a repetitive movement is always performed smoothly without damaging the member.

According to a third aspect of the present invention, the portable toilet has a recess in the front lower part .
Thereby, when moving a portable toilet, it becomes easy to move by putting a hand on this recessed part.

  According to the present invention, it is possible to transfer a user who needs care to a bed or a wheelchair to a portable toilet, a stool, or the like without assistance from a caregiver. Furthermore, the portable toilet can be easily moved to a position where the caregiver's assistance can be reduced.

One embodiment of a portable toilet with a handrail according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a portable toilet with a handrail of the present invention, FIG. 2 is a view showing the use of the portable toilet with a handrail of the present invention, FIG. 3 is a plan view of the portable toilet with a handrail of the present invention, and FIG. The figure which showed the rotation support part of the movable handrail of the portable toilet with a handrail of invention, FIG. 5 is the figure which showed a mode that the backrest was attached to the portable toilet with a handrail which is one Embodiment of this invention, FIG. It is the figure which showed the mode of use regarding the movement of the portable toilet with a handrail of this invention.

As shown in FIGS. 1 and 2, the portable toilet 1 has a toilet seat 101. Moreover, since the caster 102 is attached to the lower left and right of the back of the portable toilet 1, the front can be lifted and tilted backward, and can be moved by the caster 102.
The handrail 2 is formed by bending, and first has a horizontal portion 201 on the rear upper side of the toilet seat 101 and substantially parallel to the rear end portion 103 of the toilet seat 101. The horizontal portion 201 of the handrail 2 can be pushed downward to float forward, and the portable toilet 1 can be easily moved by the casters 102.
The rear end portion 103 refers to the rear end portion of the functional unit to which the toilet seat 101 is attached.

  Both ends of the horizontal portion 201 are bent to form an inclined portion 202 formed to be inclined downward and forward. The inclined portions 202 are disposed on the left and right sides of the toilet seat 101. The inclined portion 202 becomes a vertical portion 203 formed in a substantially vertical direction downward from a curved portion 209 bent at a position of 100 mm to 250 mm above the toilet seat 101. In the vicinity of both ends of the vertical portion 203, an attachment portion 204 for attaching the handrail 2 to the portable toilet 1 is provided.

  The portable toilet 1 includes a fixing portion 104 that fixes the attachment portion 204 of the handrail 2 behind both side surfaces. More preferably, the fixing parts 104 on both sides are provided with several points at the top and bottom, and the height at which the attachment part 204 of the handrail 2 is fixed can be adjusted according to the physique of the user, caregiver, or person who moves the portable toilet. It should be.

The attachment part 204 of the handrail 2 and the fixing part 104 of the portable toilet 1 may be fixed by any method. For example, both the attachment part and the fixing part have holes of the same size, and the inner surface of the hole has a female screw shape. They are machined and can be fixed with a single external thread.
In addition, although the material of the handrail 2 is not particularly defined, it is desirable to use a material having high rigidity, for example, iron in consideration of applying force for movement.

  The handrail 2 has a rotation support portion 205 at a position above the curved portion 209 along the inclined portion 202, and includes a movable handrail 206 that protrudes forward from this point. The movable handrail 206 is rotatable between a position substantially parallel to the toilet seat 101 and a position substantially vertical. The rotation support part 205 has a stopper that works at both positions, and can hold the position. Alternatively, if a disc spring is inserted into the rotating shaft of the movable handrail 206, the torque around the rotating shaft is adjusted by the sliding resistance of the disc spring, and the force is applied in the rotational direction, the rotational range can be moved. It can be moved only by touching or placing a hand, or the rotational torque can be changed according to the user's physical condition.

  As shown in FIG. 3, when the movable handrail 206 is at a position substantially parallel to the toilet seat 101, it passes through the center point of the rotation support portion 205 of the movable handrail 206 and the inclined portion 202 of the handrail 2. With respect to the auxiliary line 207 substantially parallel to the central axis 210, the movable handrail 206 is inclined 3 to 10 degrees on the toilet seat side (inner side). At this time, the user uses the movable handrail 206 as an armrest or the like, but there is a movable handrail 206 along the user's body so that the body can be stabilized during use, and a forward leaning posture that promotes excretion Can be kept easy even for a long time, and it is easy to put effort into the toilet.

  Further, when the movable handrail 206 is at a position substantially perpendicular to the toilet seat 101, the movable handrail 206 is inclined with respect to the auxiliary line 207 by 3 to 10 degrees on the opposite side (outside) from the toilet seat. . As a result, the movable handrail 206 does not interfere with the portable toilet body 1, and it is easy for a user in a sitting position to grasp the movable handrail 206 to lower it to a substantially parallel position, and the member is damaged. Repetitive movements are always performed smoothly.

  As shown in FIG. 3 and FIG. 4, in order to generate this angle, it passes through the center point of the connection part 213 to the inclined part 202 of the rotation support part 205 and is substantially the same as the central axis 211 of the horizontal part 201 of the handrail 2. It is necessary to install the rotating shaft 208 so as to tilt 3 to 10 degrees toward the toilet seat side with respect to the parallel auxiliary line 212. FIG. 4 shows the movable handrail omitted for easy understanding.

  In addition, a recessed portion 105 is provided in the lower front part of the portable toilet 1. This is suitable for putting a hand on a portable toilet when it is lifted and moved. Therefore, the recess 105 may have a width of 70 to 120 mm, a depth of 15 to 25 mm, and a depth of about 12 to 25 mm.

Further, FIG. 2 shows how the user uses the portable toilet with the handrail of the present invention at the time of stool.
Since it is considered that the user mainly has difficulty in moving and walking to the toilet, it is expected that the user approaches the portable toilet 1 while sitting (wheelchair or the like). Alternatively, the portable toilet 1 itself may be placed on the side of a bed that is often used by the user. Here, the user may raise the upper body (may use a bed reclining function or the like) and transfer to the portable toilet 1 in such a way as to shift his / her waist.

  For example, consider transfer from a bed as an example of use. The movable handrail 206 is lifted vertically, and the portable toilet 1 is approached by holding the curved portion 209 and shifting the waist. Next, the user stands up with the horizontal portion 201 and the other movable handrail 206 that is substantially horizontal to the toilet seat, and sits down on the toilet seat 101 of the portable toilet 1 while twisting the body. While holding down the movable handrail 206 with both hands, twist the body and shift the waist to sit on the toilet seat surface. When the transfer is completed, the vertically movable movable handrail 206 can be lowered to a position substantially horizontal to the toilet seat, and an appropriate posture can be obtained for the toilet. When the toilet is finished, the movable handrail 206 can be raised to a position substantially perpendicular to the toilet seat again and returned to the original position by the reverse operation of the seating. Thus, the portable toilet with the handrail of the present invention allows the user to use the portable toilet without the assistance of a caregiver.

  FIG. 6 shows that the portable toilet with a handrail of the present invention is transported and moved. A hand is inserted into the recess 105 in the front lower dent 106, and the front is lifted and tilted rearward to move the caster 102. Since the force can be efficiently transmitted by using the recess 105 as a clue, it can be transported and moved relatively easily.

  FIG. 5 shows an example in which the user uses the portable toilet with the handrail of the present invention without the assistance of a caregiver. The horizontal portion 201 of the handrail 2 is used by the user during normal use. Plays the role of preventing falls to the back. Therefore, by removing the toilet lid 107 and attaching the backrest 301 to the horizontal portion 201, it becomes a portable toilet with a backrest, and it is possible to support the user using the portable toilet without assistance.
