JP 2004-218357 A

In the backrest described in Patent Document 1, the grip portion at the top of the bar member is flat and difficult to grip. To make it easier to grip, it is only necessary to provide a grip at the top, but the grip must be wider than the backrest. In that case, the backrest may be damaged when a load is applied to the grip portion.
The present invention has been made based on the recognition of such a problem, and an object thereof is to provide a backrest that is not easily damaged and can be comfortably used as a backrest or a handrail.

  In order to solve the above-mentioned problem, the invention of claim 1 is a horizontally long bathroom backrest used by being provided above a horizontally long seat member provided along a wall surface of a bathroom, and the back of a person leaning on the back And a grip portion provided on an upper portion of the back support surface and formed so as to protrude from the back support surface to the wall surface side and capable of being gripped by a hand, as a resin hollow molded member A horizontally-long main body formed integrally with a bracket for attaching the main body to the wall surface, and the main body is built in the main body to release a load applied to the grip portion to the bracket. And a metal reinforcing frame attached to the bracket and end caps for closing the left and right ends of the main body.

  According to this, the backrest can be used as a backrest when sitting on the stool, as a grip when moving on the stool, or as a grip when standing up from the washing place, It can be used comfortably as a backrest or handrail. Moreover, since the reinforcement frame for escaping the load concerning a grip part to a bracket is built in, a backrest cannot be damaged easily and safety can be improved.

  The invention of claim 2 is characterized in that the reinforcing frame is formed in a substantially L-shaped cross section along the inner surface of the main body from the back surface of the hollow portion of the main body to the grip.

  According to this, the force applied to the grip when the grip that protrudes behind the back is strongly squeezed is transmitted directly to the bracket via the reinforcement frame, making it difficult to damage the back of the main body. It is.

  According to a third aspect of the present invention, a plurality of ribs continuous in the longitudinal direction are formed on at least an upper surface, a lower surface, and a wall side surface of the inner surface of the grip portion, and the reinforcing frame is formed inside the main body portion by the plurality of ribs. It is characterized by being positioned.

  According to this, a deformation | transformation of a grip part can be suppressed and damage can be prevented.

  The invention of claim 4 is characterized in that a gap is formed between the backrest surface and the reinforcing frame, and the gap is a heat insulating layer provided behind the backrest surface.

  According to this, since the temperature of the metal reinforcing frame is hardly transmitted to the back support surface by the heat insulating layer, it is possible to make it difficult to feel the coldness of the reinforcing frame even if the back is applied to the back support surface.

  The invention according to claim 5 is characterized in that a plurality of ribs continuous in the longitudinal direction from the back surface of the back support surface toward the reinforcing frame are formed.

  According to this, since the bending deformation of the back support surface is suppressed by the rib, it is difficult to feel the coldness of the reinforcing frame even when the weight is applied to the back support surface.

  The invention according to claim 6 is characterized in that the backrest surface is formed with a curved surface configured to continuously retreat toward the wall surface over the grip portion.

  According to this, since it does not feel painful even if the back is put on the backrest surface for a long time, it becomes possible to take a bath using the backrest comfortably for a long time.

  The present invention provides a backrest that is not easily damaged and that can be comfortably used as a backrest or handrail.

  The bathroom unit A shown in FIG. 1 includes a washing place 100, a bathtub 200, wall surfaces 300a and 300b made of a steel wall panel, a ceiling (not shown), and an entrance (not shown). .

  On one side surface of the washing place 100, a bench counter (seat portion) 400 is installed. The bench counter 400 is attached to an arbitrary wall surface by a support material (not shown). The bench counter 400 has a horizontally long shape so that the bench counter 400 can move sideways while sitting. At this time, since the end of the bench counter 400 is installed close to the side surface of the bathtub 200, it is possible to transfer from the bench counter 400 to the bathtub 200.

  A faucet device 500, a shower device 510, a mirror 520, and a shelf 530 are installed on the side wall surface 300 a of the bench counter 400. Thereby, the body can be washed or washed without taking an unreasonable posture while sitting on the bench counter 400.

  In FIG. 1, the bench counter 400 is provided across the bathtub 200 and the wall surface 300 a facing the bathtub 200, but the bench counter 400 is attached along the wall surface 300 a facing the bathtub 200. May be.

  A backrest 600 is installed on the wall surface 300 b behind the bench counter 400 at a position above the bench counter 400. The backrest 600 is installed in a range extending from above the bench counter 400 to above the bathtub 200. The backrest 600 can be used as a backrest for a person sitting on the bench counter 400 and as a handrail.

The backrest 600 will be described with reference to FIG.
The backrest 600 includes a hollow main body 610, a reinforcing frame 620 incorporated in a hollow portion of the main body 610, an end cap 630 that seals right and left ends of the hollow portion of the main body 610, and a main body 610. And a bracket 640 that attaches to the wall surface 300b.

The main body 610 is a long member that can be obtained by extrusion molding a resin having low thermal conductivity such as olefin or vinyl chloride. The main body 610 has a curved back support surface 611 in which a surface (front surface) opposite to the wall surface 300b to which the backrest 600 is attached is gently inflated forward. In addition, the upper end portion of the back surface of the main body 610 is inflated so as to protrude about 40 mm toward the wall surface 300b (rear side), thereby forming a grip portion 612 that can be gripped with a hand. In addition, a plurality of first ribs 613 and second ribs 614 that run in the longitudinal direction (horizontal direction in the present embodiment) are respectively provided in portions corresponding to the backrest surface 611 and the grip portion 612 of the hollow inner surface of the main body 610. Is forming.
The back support surface 611 has a height of about 120 mm to 200 mm so that the back of the person can be stably supported on a wide surface. The thickness of the back surface 611 of the main body 610 in the front-rear direction is about 20 mm, and the main body 610 has a thin shape.
The curved back support surface 611 gently bulging forward is a shape configured to be curved so as to gradually recede toward the wall surface continuously over the grip portion 612.

  The reinforcing frame 620 is a long member made of metal such as stainless steel. The reinforcing frame 620 has a plane-shaped portion 621 and a hook portion 622 that is bent from the upper end of the flat surface portion 621 toward the rear side along the grip portion 612 of the main body portion 600. It is a substantially L-shaped. The reinforcing frame 620 is inserted into the hollow portion of the main body 610 from the side of the main body 610 and integrated with the main body 610. In the state integrated with the main body portion 610, the back surface of the flat surface portion 621 contacts the rear surface of the hollow portion of the main body portion 610. Then, the reinforcement frame 620 is positioned in the main body 610 by abutting the plurality of the second ribs 614 described above around the flange portion 622. Note that the reinforcing frame 620 is not in contact with the back support surface 611 of the main body 610.

  With the reinforcing frame 620 inserted into the main body 610, the inside of the left and right ends of the main body 610 is released. In order to close the release portion, the end cap 630 is attached to seal the left and right ends of the main body 610.

A plurality of brackets 640 are provided to attach the main body 610 to the wall surface 300b at a predetermined distance. The bracket 640 includes a first member 641 having a U-shaped cross section that is attached to the wall surface 300b, a second member 642 having a U-shaped cross section that is attached to the back surface of the main body 610, a first member 641, and a second member 642. A fastening member 643 that fastens both members together, a first member 641, a second member 642, and a cover member 644 that covers the fastening member 643. Here, the second member 642 passes through a through hole formed in the back surface of the main body 610 and is fixed to a female screw hole formed in the reinforcing frame 620 with a screw 645. Since the upper portion of the reinforcing frame 620 is positioned by the second rib 614, the reinforcing frame 620 does not easily float from the back surface of the main body portion 610 even if it is fastened with screws from the back surface of the main body portion 610.
The first member 641 and the second member 642 are preferably made of stainless steel.

  Since the backrest 600 is exposed on the surface of an olefin-based or vinyl-based resin having a low thermal conductivity, the coolness felt when touched by the skin is reduced. The metal reinforcing frame 620 built in the main body 610 contacts the rear surface of the hollow portion of the main body 610 but does not contact the back support surface 611. Thereby, the cooling sensation of the reinforcing frame 620 is not directly transmitted to the back support surface 611. Moreover, since the hollow part of the main-body part 610 becomes the clearance gap formed between the back support surface 611 and the reinforcement frame 620, and becomes the air layer S, the heat insulation effect is exhibited. In other words, since the air layer S is a heat insulating layer provided behind the back support surface 611, the cooling sensation of the reinforcing frame 620 is further less likely to be transmitted to the back support surface 611. Further, since the first rib 613 provided on the inner surface of the main body 610 suppresses the bending deformation of the back support surface 611, the back support surface 611 is not easily deformed even when a load is applied to the back support surface 611, and the main body 610. The hollow part is not crushed. Therefore, even if the back of the person sitting on the bench counter 400 is leaned against the backrest surface 611, the coldness is not felt, and it can be comfortably used as the backrest.

  In addition, if the back support surface 611 is slightly bent when the back is leaned against the back support surface, cushioning is imparted to the back support surface 611 so that it can be used more comfortably as the backrest. Become.

  Further, since the back support surface 611 has a curved shape that gently swells, it is difficult to feel pain even if the back is rested for a long time.

  Furthermore, the backrest 600 seals the left and right ends of the hollow main body 610 with end caps 630. For this reason, it is possible to prevent the shower water and the water when the backrest 600 is washed from entering the main body 610.

Furthermore, since the grip portion 612 is provided at the upper end portion of the thin main body portion 610, the main body portion 610 may be deformed when a load is applied to the grip portion 612. However, in the present embodiment, a reinforcing frame 620 that is fastened to the bracket 640 and has one end built in the grip portion 612 is provided. Therefore, it is possible to directly transmit the load applied to the grip portion 611 to the bracket 640 and support the main body portion 610 with the bracket 640. Therefore, even if a load is applied to the grip portion 611, the main body portion 610 is not easily deformed, and damage to the main body portion 610 can be prevented.
Moreover, since the reinforcing frame 620 is formed in a substantially L-shaped cross section along the inner surface of the main body 610 from the back surface of the hollow portion of the main body 610 to the grip 612, the reinforcing frame 620 has a shape protruding to the rear of the backrest 600. Even if the grip portion 612 is strongly squeezed, the force applied to the grip portion 612 is directly transmitted to the bracket 640 via the reinforcing frame 620, so that the main body portion 610 is not easily damaged.

  In addition, since the tips of the plurality of second ribs 614 provided inside the grip portion 612 are in contact with the reinforcing frame 620, even if the grip portion 612 is strongly gripped, it is difficult to deform. Thereby, breakage of the grip portion 612 can be prevented.

  Next, how to use the backrest 600 will be described.

When sitting on the bench counter 400, it may lean back. At that time, it is possible to lean against the back support surface 611 of the backrest 600.
At that time, since there is a wall surface 300b made of a steel plate wall panel on the back side of the bench counter 400, it feels cold when the back touches the wall surface, but in the backrest 600 of this embodiment, the surface has a thermal conductivity. Because it is made of low resin, the coldness is reduced.

Moreover, when transferring and bathing from the bench counter 400 to the bathtub 200, it moves to the bathtub 200 and takes a bath while sitting on the bench counter 400. At this time, in order to reduce the burden of moving the body from the upper surface of the bench counter 400 to the bathtub side, it is effective to connect a flow line from the bench counter side to the bathtub side and draw the body using the backrest 600. is there.
In addition, the body tends to become unstable when straddling the bathtub 200 while sitting on the bench counter 400. Elderly people can only lift their legs while sitting without tilting their bodies. Therefore, you can transfer more stably if you have something nearby. Since the backrest 600 of this embodiment is installed at a position several tens of centimeters above the bench counter 400, the backrest 600 can support the body by grasping the grip portion 612 and can move safely and safely.

  Furthermore, the bench counter 400 can also be used as a counter. When the bench counter 400 is used as a counter, it is possible to stand up easily while supporting the body by grasping the grip portion 612 of the backrest 600 at the front when standing up from the washing place 100.

Furthermore, the backrest 600 can be used when standing over the bathtub 200 and straddling it.
According to the backrest 600 of the present embodiment, since the backrest 600 is horizontally long, the grip portion 612 can be grasped with both hands, and the body can be supported by three points of both hands and feet, and the bathtub can be more safely 200 can be straddled.
Elderly people can only lift their legs when they raise their legs. Since the center of gravity is lowered when the body is bad, the height of the position where the backrest 600 is installed is just a good height as the gripping portion. At this time, according to the backrest 600 of the present embodiment, the upper surface of the grip portion 612 is flat, which is extremely effective when supporting the body.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. For example, the reinforcing frame has a handle-like substantially L-shaped cross section, but may have a P-shaped cross section. Moreover, as long as a hollow part is formed in the inside of the main part of a backrest, what was manufactured by manufacturing methods other than extrusion molding is also included in this invention. Furthermore, a drain hole can be provided in the lower part of the main body of the backrest so that the internal condensed water can be discharged.
