Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an armrest, in particular a foldable armrest, which is used, for example, by a person with a physical disability to support the body in a toilet or the like.

(Prior Art) Conventionally, this type of armrest has been configured to be fixedly attached to a toilet or the like.

(Problems to be Solved by the Invention) However, the fixed configuration as described above has the problem of being a hindrance to healthy people.

Therefore, it is an object of the present invention to provide a foldable armrest that solves the above problems.

(Means for Solving the Problems) The present invention is designed to pivot one end of an armrest main body to a pair of side walls that stand upright from a holding member fixed to a wall or the like so as to be rotatable between a substantially horizontal direction and a substantially vertical direction. one end of the stay is rotatably supported between a substantially parallel direction and an acute angle direction with respect to the armrest main body on a body attached to a lower part near the other end of the armrest main body, and the stay is attached near one end of the armrest main body. A ball energized to come into contact with one side of the side wall is provided therein, and a hole is provided in the same rotation locus of the ball above one of the side walls in the vertical direction, and the ball is fitted into the hole. The body is configured to obtain a semi-fixed state, and a caster is rotatably attached to the other end of the stay, and a stopper is provided on the body to engage with the stay in order to hold the stay at an acute angle with respect to the armrest main body. The gist of the invention is a folding armrest in which a caster abuts an intersection between a wall and a floor to maintain the armrest main body in a substantially horizontal direction.

(Function) With the above configuration, when the armrest main body is lifted near the tip of the main body from a substantially horizontal use state and rotated upward in the vertical direction, the armrest main body is moved by fitting the ball into the hole provided in the holding member. It is in a semi-fixed state and is held approximately parallel to the wall. On the other hand, since the stay is in a free state, it hangs down and is held in a direction substantially parallel to the armrest body.

Next, when putting it into use, if you pull strongly downwards near the tip of the armrest body, the semi-fixed state will be released and the caster will come into contact with the floor, but the stay will Since the caster is held at an acute angle with respect to the wall, the caster rotates on the floor toward the wall and is held in contact with the intersection between the wall and the floor. At that time, the armrest main body is held in a substantially horizontal direction.

(Example) Fig. 1 shows the folding armrest of the present invention, a is a side view, b is a front view thereof, Fig. 2 is an enlarged view of a holding member, a is a side view, and b is a cross-sectional view taken along the line A-A. It is. In the figure, reference numeral 1 denotes a holding member having a bottom portion 10a fixed to a wall 3 with a plurality of screws 2, and a pair of substantially semicircular side walls 10b and 10c standing upright from the bottom portion. One end of an armrest main body 6, which is a square pipe, is attached to the side walls 10b, 10c of the holding member 1 by bolts 4 and nuts 5, so that it can rotate between a substantially vertical direction and a substantially horizontal direction. On the other hand, near one end of the armrest main body 6, as shown in FIG. 2b,
A ball 7 and a hole 11 (described later) in the holding member 1.
A spring 8 is provided inside the spring 8 to urge it to come into contact with one side wall 10b, and an adjustment bolt 9 for adjusting the spring constant of the spring 8 is provided on the side facing the ball 7. Therefore, ball 7
is configured to rotate between the substantially vertical direction and the substantially horizontal direction about the bolt 4 while being constantly biased toward one side wall 10b of the holding member 1 together with the armrest main body 6 that holds it. Now, the hole 11 mentioned above is located above the one side wall 10b in the vertical direction,
The bolts 7 are provided on the same rotation locus around the bolt 4 and have a slightly smaller diameter than the diameter of the ball 7, so that when the armrest main body 6 is rotated and lifted upward, the ball 7 will move through this hole. 11 to hold the armrest main body 6 in a semi-fixed state. On the other hand, a body 12 is attached to the lower part near the tip of the armrest main body 6, and one end of the stay 13 is rotatably supported on the body 12 by a bolt 14 and a nut 15, so that the armrest main body 6 is held in a vertical direction. The other end of the stay 13 hangs down due to its own weight and is held in a direction substantially parallel to the main body of the armrest.A caster 16 is rotatably attached to the other end of the stay 13, and the caster 16 is connected to the wall 3 and the floor. When the armrest body 6 comes into contact with the intersection 17, the armrest body 6 is maintained in a substantially horizontal direction. This caster 16 is mounted so as to rotate in the direction of the wall on the floor 17, and furthermore,
When the stay 13 is suspended on the floor, the body 12 is configured to maintain an acute angle direction with respect to the armrest main body 1.
A stopper 18 that engages with the stay 13 is provided.

Next, we will discuss its effect.

The solid line diagram in FIG. 1 shows the used state. To change from this state to the unused state, hold the armrest main body 6 near the tip and rotate it upward (in the direction of arrow A), and the ball 7 will be moved by the spring 8. When the armrest main body 6 rotates approximately 90 degrees and is positioned approximately vertically by rotating while abutting one side wall 10b of the holding member 1, the ball 7 moves into the hole 1 in the same rotation restriction.
1, the armrest main body 6 becomes semi-fixed and is held in a direction substantially parallel to the wall 3. On the other hand, since the stay 13 is in a free state, it hangs down due to its own weight and is held in a direction substantially parallel to the armrest main body 6, as shown by the two-dot chain line.

Next, to put it into use, reverse the armrest body 6.
If the vicinity of the tip is strongly rotated downward (in the direction of arrow B), the ball 7 will come out of the hole 11 and the semi-fixed state will be released. When the downward rotation is continued, the stay 13 initially hangs straight down and descends, but it is stopped halfway by the stopper 13 and remains at an acute angle with respect to the armrest main body 6 (as shown in the figure). In the example, the caster 16 contacts the floor 17 at an angle of about 45 degrees), the caster 16 rotates and contacts the intersection of the floor 17 and the wall 3, and the armrest main body 6 is maintained in a substantially horizontal direction and is ready for use. In addition,
The adjustment bolt 9 may not be provided in the above-described device for maintaining the semi-fixed state.

(Effects of the invention) As explained in detail above, the invention has the advantage that it can be switched between use and non-use with a single touch, and can be used by both healthy people and people with physical disabilities. Note that the armrests of the present invention can be used more effectively if a pair is placed on both sides of the toilet bowl.
