JP6450099B2 - Bathtub with bathtub pillow and bathtub pillow - Google Patents

Description

  The present invention relates to a bathtub pillow that is attached to a bathtub by a suction cup, and more particularly, to a structure for attaching a bathtub pillow and a suction cup.

  The bathtub pillow is attached to the outer edge of the bathtub so that the bather leans his head or neck (see Patent Documents 1 and 2). In view of hygiene, the bathtub pillow needs to be removed from the bathtub and dried when not in use, so that the bathtub pillow is preferably removable. It is necessary to remove the bathtub pillow when cleaning the bathtub. The bathtub pillows described in Patent Documents 1 and 2 each include a suction cup, and are attached to the bathtub by the suction force of the suction cup.

Registered Utility Model No. 3044113 JP 2004-350960 A

  The service life of the suction cup is much shorter than that of the bathtub pillow body. Since the suction cups made of elastic synthetic resin such as polyvinyl chloride, elastomer, and polyethylene are consumables, they need to be replaced about once a year. However, in Patent Document 1, since the suction cup is bonded and fixed to the bathtub pillow, the suction cup cannot be replaced.

  Patent Document 2 discloses a structure in which a suction cup is fitted into a fixed plate built in a bathtub pillow. However, since the bathtub pillow of patent document 2 is a structure which hooks the projection part of a suction cup on the hole of a fixed plate, a suction cup tends to remove | deviate from a bathtub pillow. For this reason, when removing a bathtub pillow from a bathtub, there exists a possibility that only a bathtub pillow main body may come off, with a suction cup adhering to a bathtub. Furthermore, although details will be described later, since stress tends to concentrate on a part (neck portion) of the suction cup, there is a concern that the suction cup is likely to be deteriorated or worn.

  This invention is made | formed in view of the said subject, The main objective is to provide the technique which raises the coupling force of a bathtub pillow and a suction cup, making a suction cup removable from a bathtub pillow.

In order to solve the above problems, a bathtub pillow according to an aspect of the present invention includes a head holding member, a fixing member having a protrusion, and a suction cup member having a tube portion and a suction portion.
The fixing member is fixed to the head holding member with the protruding portion protruding downward, and the suction cup member is detachably attached to the fixing member by fitting the cylindrical portion into the protruding portion. It wrapped by the tubular portion to the root, in a state of fitting the cylindrical portion to the projecting portion, the tubular portion that has grown up above the root of the protrusion.

  The “head holding member” is a portion that receives a bather's head or neck, and preferably has elasticity. The head holding member and the fixing member may be bonded and fixed. The head holding member, the suction cup member, and the bathtub are detachably coupled to each other. The suction cup member and the bathtub are adsorbed by the suction force of the suction cup. On the other hand, the fixing member and the suction cup member are coupled together by the protruding portion of the fixing member being wrapped and gripped by the cylindrical portion of the suction cup member. Since the projecting portion is wrapped with the cylindrical portion, the coupling force between the fixing member and the suction cup member is increased.

  The suction cup member may be attachable to the fixing member such that the top of the protrusion is in close contact with the bottom of the tube.

  The side surface of the protruding portion may be in contact with the inner side surface of the cylindrical portion, and the top portion (tip) of the protruding portion may be in contact with the inner bottom surface of the cylindrical portion. According to such an aspect, since the force applied to the protrusion can be received not only on the side surface of the protrusion but also on the top, it becomes easy to stably couple the fixing member and the suction cup member.

  The tube portion may be cylindrical, and the protrusion may be spherical.

  When the protrusion is spherical, it is easy to push the protrusion into the cylinder smoothly and to pull it out smoothly. Thereby, it becomes easy to attach and detach a projection part and a cylinder part.

  The maximum outer diameter of the protruding portion may be larger than the minimum inner diameter of the cylindrical portion.

  By making the maximum outer diameter of the protruding portion larger than the minimum inner diameter of the cylindrical portion, the cylindrical portion can easily hold the protruding portion firmly when the protruding portion is pushed into the cylindrical portion. In addition, when the cylindrical portion is elastic, the cylindrical portion is deformed along the shape of the protruding portion, so that the cylindrical portion is easy to enclose the protruding portion.

  The head holding member may be provided on the lower surface with a concave accommodating portion in which a water discharge device provided on the outer edge of the bathtub is accommodated.

  By providing the head holding member so as to cover the water discharging device, the bather can receive water discharge from the water discharging device under the head holding member to the neck and shoulders in an easy posture with the head on. .

  Another aspect of the present invention is a bathtub with a bathtub pillow, and includes the bathtub and the above-described bathtub pillow. The bathtub pillow may be bonded and fixed to the outer edge of the bathtub by a sucker member.

  ADVANTAGE OF THE INVENTION According to this invention, the coupling | bonding force of a bathtub pillow and a suction cup can be heightened, enabling removal of a suction cup from a bathtub pillow.

FIG. 1 is a perspective view of the bathtub 102 and the bathtub pillow 100.
The bathtub 102 sets the y direction as the long direction and the x direction as the short direction. A water discharge device 104 is fixedly installed on the outer edge portion 106 of the bathtub 102. The water discharging apparatus 104 discharges the water pumped up from the bathtub 102 by a pump (not shown) into the bathtub 102 as band-shaped water. The main material of the water discharger 104 is resin.
A bathtub pillow 100 is installed on the water discharge device 104. The bathtub pillow 100 includes a concave accommodating portion 110, and the water discharge device 104 is accommodated in the accommodating portion 110. The upper side of the housing part 110 corresponds to the head holding part 116.

The bather puts his head on the head holding portion 116 of the bathtub pillow 100 and leans against the inner wall of the bathtub 102 and receives water discharge from the water discharge device 104 under the bathtub pillow 100 to the neck and shoulder. Both the water discharge device and the bathtub pillow 100 are structures for enhancing the relaxation effect of the bather. In addition, in this invention, the water discharging apparatus 104 is not an essential structure, You may install only the bathtub 102 and the bathtub pillow 100. FIG.
The head holding portion 116 of the bathtub pillow 100 preferably has water resistance, appropriate strength, and elasticity, and is preferably formed of a soft synthetic resin such as vinyl chloride or urethane foam.

FIG. 2 is a rear perspective view of the bathtub pillow 100.
A housing portion 110 that houses the water discharge device 104 is formed at the center of the back surface of the bathtub pillow 100, in other words, below the head holding portion 116. The suction cup storage portions 108 are formed on both sides of the storage portion 110. Although details will be described later, a suction cup member 114 (described later) is attached to the suction cup storage portion 108, and the bathtub pillow 100 is fixed to the bathtub 102 by the suction cup member 114 adsorbing to the outer edge portion 106 of the bathtub 102. .

FIG. 3 is a cross-sectional view showing a state before the suction cup is attached in the suction cup storage portion 108. FIG. 3 corresponds to the cross section indicated by the line AA in FIG. FIG. 4 is a perspective view of the fixing plate 112 and the suction cup member 114.
The fixing plate 112 (fixing member) includes a disc portion 118 and a protruding portion 120. The protrusion 120 in the present embodiment is spherical. The fixing plate 112 preferably has rigidity and thermoplasticity. The fixing plate 112 in the present embodiment is polyphenylene sulfide (PPS). PPS is characterized by excellent heat resistance and chemical resistance, and extremely high strength and rigidity.

  A plurality of holes 126 are formed in the disc portion 118. In the manufacturing process of the bathtub pillow 100, when heat is applied in a state where the disk portion 118 of the fixed plate 112 is inserted into the bathtub pillow 100, the resin of the bathtub pillow 100 partially melts and fills the hole 126 of the disk portion 118. . Thereby, the fixing plate 112 is firmly fixed inside the bathtub pillow 100. Once molded, it is not assumed that the fixing plate 112 is removed from the bathtub pillow 100.

  The suction cup member 114 includes a suction portion 124 and a cylindrical portion 122. The cylinder part 122 in this embodiment is a cylinder. The suction cup member 114 is formed of a synthetic resin having elasticity such as polyvinyl chloride or polyethylene.

  The protrusion 120 of the fixing plate 112 is exposed from the lower part of the bathtub pillow 100. The maximum outer diameter W1 of the protruding portion 120 is larger than the inner diameter W2 of the cylindrical portion 122. The suction cup member 114 is fixed to the bathtub pillow 100 by pushing the protruding portion 120 into the cylindrical portion 122.

FIG. 5 is a cross-sectional view showing a state after the suction cups are attached in the suction cup storage part 108. FIG. 5 also corresponds to the AA line in FIG.
When the maximum outer diameter W1 of the protruding portion 120 is larger than the inner diameter W2 of the cylindrical portion 122, and the suction cup member 114 has elasticity, while the fixing plate 112 has high rigidity, the protruding portion 120 is pushed into the cylindrical portion 122. The cylindrical portion 122 is deformed to wrap the protruding portion 120.

  Further, the top (tip) of the protrusion 120 is in contact with the bottom of the cylindrical portion 122. Since the protrusion 120 contacts the cylindrical portion 122 not only at the side surface but also at the top, the contact area between the protruding portion 120 and the cylindrical portion 122 is increased. That is, the protrusion 120 is almost entirely encased by the cylindrical portion 122. As a result, not only the gripping force (restoring force) of the cylindrical portion 122 is easily transmitted to the projecting portion 120, but also the gripping force is evenly diffused without concentrating on some places. Although not essential, the tip of the cylindrical portion 122 also contacts the disc portion 118.

  Next, in order to clarify the characteristics of the structure described above, a comparative example based on the technique described in Patent Document 2 will also be mentioned.

FIG. 6 is a perspective view of the fixed plate 128 and the suction cup member 130 in the comparative example.
In the comparative example, the suction cup member 130 has a protrusion 132, and the fixing plate 128 is provided with an engagement hole 134 instead of a protrusion. The engagement hole 134 has a shape in which the large hole 136 and the small hole 138 are connected. When the suction cup member 130 is coupled to the fixing plate 128, first, the protrusion 132 of the suction cup member 130 is inserted into the large hole 136, and the suction cup member 130 is slid into the small hole 138 after the insertion, thereby attaching the suction cup member 130 to the fixing plate 128. Connect to.

FIG. 7 is a cross-sectional view of the suction cup storage portion 108 in the comparative example.
As described above, the suction cup member 130 is inserted into the large hole 136 of the fixing plate 128 and is slid into the small hole 138. In the case of such a structure, the following problems arise.

(1) The suction cup member 130 is easily detached when the main body of the bathtub pillow 100 is displaced in the lateral direction (y direction). Even if the suction cup member 130 is stabilized in the small hole 138 of the engagement hole 134, when the bathtub pillow 100 moves in the y direction (the positive y direction in FIG. 7), the protrusion 132 of the suction cup member 130 is positioned at the large hole 136. The suction cup member 130 is detached from the fixed plate 128. For this reason, when the bathtub pillow 100 is removed from the bathtub 102, there is a possibility that only the main body of the bathtub pillow 100 may come off while the suction cup member 130 remains adsorbed on the bathtub 102.

(2) Stress tends to concentrate on the neck 140 of the protrusion 132.
Since the neck portion 140 (recess) of the protrusion 132 is supported by the small hole 138, stress concentrates on the neck portion 140. The suction cup member 130 is less durable than the fixed plate 128 or the like because elasticity is required. For this reason, the suction cup member 130 may be torn from the neck portion 140 due to contact stress with the hard fixing plate 128.

  On the other hand, in the bathtub pillow 100 according to the present embodiment, since the soft cylindrical portion 122 wraps the protruding portion 120 of the fixing plate 112 from almost all directions, the cylindrical portion can be applied to the bathtub pillow 100 regardless of the vertical or horizontal direction. 122 can hold the protrusion 120 firmly.

  Further, since the cylindrical portion 122 wraps the protruding portion 120, local stress is not easily applied to the protruding portion 120 and the cylindrical portion 122. Furthermore, in this embodiment, since the protrusion 120 is formed on the side of the fixing plate 112 that can ensure rigidity, the protrusion 120 itself is resistant to stress.

  In the case of the comparative example, it is necessary to insert the protrusion 132 into the large hole 136 and slide it, but in the case of the present embodiment, the protrusion 120 is simply pressed against the tube portion 122 from directly above. is there.

  When the bathtub pillow 100 is peeled from the bathtub 102, the bathtub pillow 100 is pulled upward. However, since the force with which the cylindrical portion 122 grips the suction cup member 130 is stronger than the force with which the suction cup member 114 adsorbs to the bathtub 102, only the suction cup member 114 It does not remain adsorbed in the bathtub 102. Since the gripping force of the cylindrical portion 122 is large, there is also an advantage that a large suction cup member 114 having an attractive force can be employed. When removing the suction cup member 130 from the fixed plate 112, it is only necessary to pinch and pull the suction cup member 130.

  The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .

  For example, the protrusion 120 of the fixing plate 112 does not need to be spherical, and the cylindrical portion 122 of the suction cup member 114 does not need to be cylindrical. That is, it is only necessary that the protrusion formed on the fixing plate 112 can be sandwiched by a cylinder formed on the suction cup member 114. As an example, a combination of a rectangular parallelepiped protrusion 120 and a rectangular tube 122 may be used. Similarly, the disk part 118 of the fixing plate 112 does not need to be a disk, and may be a shape that can be fixed inside the bathtub pillow 100. The fixed plate 112 has higher rigidity and strength than the suction plate member 114, and the suction plate member 114 may be formed of a material having greater elasticity than the fixed plate 112.

In the present embodiment, the bathtub pillow 100 has been described, but the suction cup connection structure in the present embodiment can be applied to other than the bathtub pillow. For example, the present invention can be applied to a bathtub mat that is laid on the bottom of the bathtub to prevent slipping. For this reason,
A fixing member having a protrusion, and
A suction cup member having a cylindrical portion and a suction cup,
The suction cup attachment structure, wherein the suction cup member is detachably attached to the fixing member by fitting the cylindrical portion into the protrusion.
However, the invention can be recognized.
