Description

  The present invention relates to a bathtub lid that covers the upper surface opening of a bathtub and prevents a drop in hot water temperature.

  In order to increase the heat insulation capacity of the hot water in the bathtub, not only the heat insulation performance of the bathtub body is improved, but also the bathtub lid that covers the top opening of the bathtub requires particularly high heat insulation performance.

In addition to a shutter type that can be rolled in and a foldable type that can be folded, a combination of a plurality of thin plate-like panels such as a set of two or a set of three is used for the bathtub lid. A combination-type bathtub lid is known.

Of these, in combination type lids for bathtubs, in order to improve heat insulation performance, as described in the following patent document, hard polypropylene is provided on both front and back surfaces of a heat insulation core material made of synthetic resin foam or the like. A cover body is formed by laminating and integrating decorative panels made of resin or aluminum thin plate, and an edge protector made of elastomer or soft synthetic resin that exhibits an anti-slip effect is fitted to the periphery of the cover body. Those configured are generally commercially available.
Japanese Patent Laid-Open No. 11-32930

  In the case of a combination-type bathtub lid in which an edge protector is fitted to the outer peripheral edge of the lid body, the top surface of the flange portion of the bathtub body maintains a horizontal state, the lid body is not warped, and the edge protector also has its longitudinal direction. If a horizontal state is maintained along the gap, no gap is formed between the two in the lid-covered state, and a decrease in hot water temperature can be prevented.

  However, as disclosed in the above-mentioned patent documents, the conventional edge protector has a recess for embedding the peripheral edge of the lid body on the inside, and the outside is against the upper surface of the flange portion of the bathtub body. Only the thick part to be touched is formed, and even if the upper surface of the flange part of the bathtub body maintains the horizontal state, the contact surface of the edge protector of the lid body is accurately held horizontally. It was impossible or very difficult to do.

  Therefore, in the state where the lid body is placed on the upper surface opening of the bathtub body, there are usually some gaps between the flange body upper surface of the bathtub body and the edge protector. Since it was taken in in a bathtub, there existed a problem of causing the fall of hot water temperature.

  In recent years, bathtubs with headrests have been put on the market in response to consumer needs. In this case, a gap is easily formed between the headrest and the lid body, resulting in a decrease in hot water temperature. There is a problem that it becomes a factor inviting.

  Therefore, the object of the present invention is that no gap is formed between the main body of the bathtub in the lid-covered state, and it is possible to prevent the steam from being dissipated and to effectively prevent the decrease in the hot water temperature. The object is to provide a bathtub lid.

If the structure of this invention for achieving the said objective is explained in full detail, the invention which concerns on Claim 1 will attach an edge protector to the peripheral part of a cover main body, and the said edge protector will contact | abut to the upper surface of the flange part of a bathtub. In the bathtub lid, a synthetic resin tube body that can be freely deformed corresponding to the shape of the upper surface of the bathtub is formed on the outer periphery of the edge protector, and any of the synthetic resin tube bodies A bathtub lid characterized in that a small hole that communicates with the outside air is formed in a location, and the synthetic resin tube body is brought into contact with the upper surface of the flange portion of the bathtub when the lid is applied.

According to a second aspect of the invention, in the bathtub lid in which an edge protector is attached to the peripheral edge of the lid body, the outer periphery of the edge protector is freely deformed corresponding to the shape of the headrest provided in the bathtub. A possible synthetic resin tube body is formed, and a small hole communicating with the outside air is drilled at an arbitrary position of the synthetic resin tube body, and the synthetic resin tube body is provided in the bathtub at the time of covering. It is a lid | cover for bathtubs characterized by making it contact | abut to the headrest which is.

  In the invention according to claim 3, the synthetic resin tube body is integrated not only with the portion corresponding to the headrest provided in the bathtub, but also with the portion corresponding to the upper surface of the linear flange portion of the bathtub connected to the headrest. The bathtub lid according to claim 2, wherein the bathtub lid is formed as described above.

  In the present invention, as described above, an inner hollow synthetic resin tube body as a gap filling body that can be freely deformed corresponding to the shape of the upper surface of the bathtub is formed on the outer peripheral portion of the edge protector. Even if there is a slight unevenness on the upper surface of the flange part of the bathtub body, or even if the lid body is slightly warped due to thermal deformation etc., the tube body on the outer edge of the edge protector is freely deformed and the slight unevenness part In addition, gaps based on warpage can be closed.

  In the case of a bathtub provided with a headrest, there may be a gap between the headrest portion and the lid body, but by attaching a synthetic resin tube body to a location corresponding to the headrest, The gap can be eliminated and heat release from this portion can be prevented.

  Since the present invention is such that a synthetic resin tube body that can be freely deformed in accordance with the shape of the upper surface of the bathtub body is attached to the outer periphery of the edge protector, the upper surface of the flange portion of the bathtub body is covered with the lid body. In the state, there is no gap between the edge protector and the upper surface of the bathtub, so that the dissipation of steam can be prevented and the decrease in the temperature of the hot water can be effectively prevented. Also, in the case of a special type bathtub provided with a headrest, the synthetic resin tube body can be freely deformed corresponding to the shape of the headrest, and heat dissipation from the headrest peripheral portion can be prevented.

In addition, since a small hole that leads to the outside air is drilled at an appropriate location on the synthetic resin tube body, the synthetic resin tube body is not affected by thermal expansion, and the tube body is shaped like the top surface of the flange portion of the bathtub body. Alternatively, it can be instantly deformed corresponding to the shape of the headrest, and the gap between the bathtub body and the lid body can be filled.

  Hereinafter, embodiments of a lid for a bathtub according to the present invention will be described in detail with reference to the drawings.

  1 is a plan view showing an embodiment of the lid for a bathtub of the present invention, FIG. 2 is an enlarged cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is an edge protector in which a tube body is formed as a gap filling body. FIG. 4 is an enlarged cross-sectional view showing an embodiment, FIG. 4 is an enlarged cross-sectional view showing an embodiment of an edge protector in which a tube body is formed in the central portion of the outer periphery of the edge protector, and FIG. FIG. 6 is an explanatory diagram showing an example of a state in which the tube body is in contact with the headrest provided in the bathtub and the gap is filled, and FIG. It is a top view which shows other embodiment of the lid | cover for this invention bathtub made to respond | correspond to the provided bathtub.

  In the figure, reference numeral 1 denotes a thin plate-like lid body in a combination lid that is a pair of two corresponding to the size of the bathtub, and 2 is an elastomer having a non-slip effect fitted to the entire outer peripheral edge of the lid body 1. An edge protector made of soft or synthetic resin.

  In the case of the illustrated embodiment, the lid body 1 has decorative plates 4 and 4 made of hard polypropylene resin or aluminum thin plate on both front and back surfaces of a heat insulating core material 3 having high heat insulating performance such as a synthetic resin foam. The lid for the bathtub as an object for carrying out the present invention is not limited to this, but is formed into a thin plate as a whole and required as a lid for the bathtub. Of course, it may be other than the laminated structure as long as it has heat insulation performance or heat resistance.

  The edge protector 2 has a recess in which the peripheral edge of the lid main body 1 can be tightly fitted, and a synthetic resin tube body 5 is continuously projected along the outer periphery in the longitudinal direction. The synthetic resin tube body 5 can be extruded at the same time as the edge protector 2 is formed. However, the tube body 5 is produced separately from the normal edge protector 2 extrusion, and this is used as the edge protector 2. Of course, the outer peripheral portion may be attached later by means such as adhesion or welding.

  In addition, what is called the tube body 5 here represents a state in which the edge protector 2 is formed to protrude, and when it is retrofitted to the edge protector 2, in addition to the complete tube body, This includes a case where the edge protector 2 is formed on the edge protector 2 and the tube body 5 is formed as a whole by using the substrate of the edge protector 2.

  Since the synthetic resin tube body 5 is required to be flexible, a synthetic resin foam is preferably used, but can be freely deformed in accordance with the shape of the top surface of the flange portion of the bathtub or the shape of the headrest in the covered state. If it is possible, a general-purpose soft synthetic resin can be used.

  In the case of a lid for a bathtub used as a set of two pieces as shown in FIG. 1, butted portions 6 and 6 of the lid main bodies 1 and 1 that do not come into contact with the upper surface of the flange portion of the bathtub in the covered state are generated. In addition, it is not necessary to form the synthetic resin tube body 5 at the butting portions 6 and 6. However, if the synthetic resin tube body 5 is projected at the butting portions 6 and 6, the gap formed between the butting portions 6 and 6 of the lid bodies 1 and 1 can be filled, and high heat retaining performance can be obtained. Obtainable.

  Moreover, although the synthetic resin tube body 5 may be protruded only in a portion corresponding to the headrest 10 formed in the bathtub body 7, the headrest provided in the bathtub body 7 as shown in FIG. The tube body 5 is integrally formed not only in the portion corresponding to 10 but also in the portion corresponding to the linear upper surface of the flange portion 8 connected to the headrest 10, thereby further improving the adhesion with the bathtub body 7. It can be done.

  Further, as in the embodiment shown in FIG. 7, the tube is integrally formed not only on the portion corresponding to the headrest 10 provided on the bathtub body 7 but also on the portion corresponding to the linear upper surface of the flange portion 8 connected to the headrest 10. Even if the body 5 is formed, the tube body may not be attached to the other sides. In this case, the side where the tube body is not attached is a case having good adhesion to the bathtub body 7.

  The formation position of the synthetic resin tube body 5 is optimal in the vicinity of the lower corner portion of the edge protector 2 that comes into contact with the upper surface of the flange portion 8 of the bathtub body 7 in the covered state as shown in FIGS. However, the tube body 5 may be enlarged so as to cover the entire outer periphery of the edge protector 2. It is most preferable that the vicinity of the joint portion between the tube body 5 and the edge protector 2 has a gently curved shape in consideration of the cleaning property or durability.

  Moreover, even when the tube body 5 is formed in the vicinity of the lower corner of the edge protector 2 as shown in FIG. 3, it corresponds to the bathtub body 7 provided with the headrest 10 as shown in FIG. Is fully possible. However, as shown in FIG. 4, the tube body 5 may be formed near the center of the outer periphery of the edge protector 2, and the tube body 5 may correspond to the bathtub body 7 in which the headrest 10 is provided. Of course.

  The synthetic resin tube body 5 formed on the outer periphery of the edge protector 2 is brought into contact with the upper surface of the flange portion 8 of the bathtub body 7 due to an increase in internal pressure due to thermal expansion or the like when the inside is blocked from outside air. Since it becomes difficult to be deformed sometimes, a small hole 9 communicating with the outside air is drilled at an appropriate position of the tube body 5, for example, at an appropriate upper position of the tube body 5 as shown in FIG. 3.

  As a result, the tube body 5 is instantly deformed corresponding to the shape of the upper surface of the flange portion 8 of the bathtub body 7 or the shape of the headrest 10, and the gap between the bathtub body 7 and the lid body 1 can be filled. It should be noted that the position where the small hole 9 is drilled is arbitrary, and although it is not particularly illustrated, it is needless to say that the small hole 9 may be provided in a shielding portion that covers the terminal portion of the tube body 5.

  As described above, the bathtub lid of the present invention is a hollow synthetic resin tube as a gap filling body that can be freely deformed in accordance with the upper surface shape of the flange portion 8 of the bathtub body 7 on the outer peripheral portion of the edge protector 2. Even if there is a slight unevenness on the upper surface of the flange portion 8 of the bathtub body 7 or the lid body 1 is slightly warped due to thermal deformation or the like, the outer periphery of the edge protector 2 is formed. The tube body 5 of the part can be freely deformed to close the slight uneven part and the gap based on the warp, and a high heat retaining effect can be obtained.

Of course, the synthetic resin tube body 5 may be formed along the entire periphery of the edge protector 2, but when a gap is assumed between the flange body 8 of the bathtub body 7 in advance. Alternatively, the tube body 5 may be formed only in the assumed portion.

  Further, in the case of a bathtub provided with a headrest, a gap may be formed between the headrest portion and the lid body, but by attaching the synthetic resin tube body 5 to a location corresponding to the headrest. The gap can be eliminated and the heat radiation from this portion can be prevented.
