Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a shutter-type bath lid that can be rolled in from a closed state when placed on the edge of a bathtub.

[0002]

[Prior art and its problems]

 Generally, a shutter-type bath lid has a structure in which a large number of hollow rod-shaped bodies made of extruded hard synthetic resin are connected in parallel via flexible synthetic resin band-shaped connecting members. The advantages are that you can easily open and close the bathtub lid by rolling it up and unfolding it, and when it is not in use, it can be placed horizontally beside the bathtub or stand upright in the corner of the bathroom in a compact rolled-up state.

Conventionally, as such a shutter-type bath lid, a hollow rod-shaped body is made of hard polyethylene, a hard vinyl chloride resin, or the like, and a band-shaped connecting material is inexpensive and has good moldability and also has a non-slip effect. A product obtained by integrally molding the hollow rod-shaped body and the belt-shaped connecting material by coextrusion using a vinyl resin is widely used. However, the bath lid whose hollow rod-shaped body is made of hard polyethylene or hard vinyl chloride resin has a drawback that it is inferior in heat resistance and strength.

Therefore, the present inventors have examined the use of ABS resin, which is excellent in heat resistance and strength, as the resin material for the hollow rod-shaped body, but when a soft vinyl chloride resin is used for the belt-shaped connecting material, Due to the poor affinity between soft vinyl chloride resin and ABS resin, even if the hollow rod-shaped body and the band-shaped connecting material are co-extruded together, the adhesion strength at the joint interface will be insufficient, making it suitable for use in bath lids. It was found that the strip-shaped interconnecting material was easily peeled off from the hollow rod-shaped body due to repeated entrainment and deployment.

An object of the present invention is to provide a high-grade shutter-type bath lid that is excellent in heat resistance and strength, has a large bonding strength between the hollow rod-shaped body and the belt-shaped connecting member, and is highly durable.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a shutter type bath lid according to claim 1 of the present invention comprises a plurality of ABS (acrylonitrile-butadiene-styrene copolymer) hard extruded products arranged in parallel. A hollow rod-shaped body and a flexible vinyl chloride resin-made foldable belt-shaped connecting material interposed between adjacent hollow rod-shaped bodies are formed in a wide groove along the longitudinal direction formed on the lower surface side of the hollow rod-shaped body. A structure is used in which the ridges of the connecting material are embedded to form an integral connection by a concave-convex fitting structure.

In the shutter-type bath lid according to the first aspect, the hollow rod-shaped body and the band-shaped connecting member are made of a synthetic resin component that is hard to bond strongly to each other. Even if a load is applied, since the connecting portion is integrated by engaging with the dovetail-shaped concave-convex fitting structure, the connecting portion does not come off, and thus exhibits extremely excellent durability. However, since the hollow rod-shaped body of this bath lid is made of ABS resin, it has better heat resistance and strength as a whole than the ordinary bath lid that uses a hollow rod-shaped body made of hard polyethylene or hard vinyl chloride resin. In addition to being excellent, the band-shaped connecting material is made of soft vinyl chloride resin, so it is inexpensive and has good moldability. In addition, the soft vinyl chloride resin surface of this band-shaped connecting material serves as the contact surface with the edge of the bathtub and is good in the closed state. Good anti-slip action is obtained.

According to a second aspect of the present invention, in the shutter-type bath lid according to the first aspect, a band-shaped non-slip member made of a soft vinyl chloride resin is attached to a central position in the width direction of the lower surface of the hollow rod-shaped body. Therefore, when the lid is closed, the soft vinyl chloride resin surfaces of both the strip-shaped connecting material and the strip-shaped anti-slip material come into contact with the bathtub edge, and a better anti-slip action can be obtained.

[0009]

[Embodiment of device]

 FIG. 1 shows a partial cross section of a shutter-type bath lid according to the first embodiment of the present invention, and FIGS. 2 and 3 show enlarged views of imaginary line circles A and B in FIG. 1, respectively. In this shutter type bath lid, a large number of hollow rod-shaped bodies (1) made of hard extruded ABS resin are connected in parallel through strip-shaped connecting members (2) made of soft vinyl chloride resin. In addition to being bonded, a band-shaped non-slip material (3) made of soft vinyl chloride resin along the longitudinal direction is adhered to the center position of the lower surface of each hollow rod-shaped body (1).

Each of the above hollow rod-shaped bodies (1) has a substantially trapezoidal cross section composed of an upper plate part (11) and a bottom plate part (12) and left and right side plate parts (13) (13) having a V-shaped cross section. However, the internal space is partitioned by the reinforcing wall portion (14) located at the center in the width direction and continuous in the longitudinal direction. The bottom plate portion (12) has grooves (4) (4) with an inverted trapezoidal cross section located on both sides in the width direction of the lower surface (only one side in the hollow rod-shaped body positioned at both ends of the bath lid) and the lower surface. A groove (5) having a notched circular cross section located in the center of the groove is formed along the longitudinal direction, and the groove (4) (4) formed on both sides is a stepped portion (1) bulging toward the hollow inside. The wall thickness is secured as 2a).

On the other hand, each of the band-shaped connecting members (2) has ridge portions (2a) (2a) having a dovetail-shaped cross section on both sides in the width direction, and both ridge portions (2a) (2a) are provided. The hollow rod-shaped bodies (1) and (1) on both sides are connected so as to be embedded in the grooves (4) of the hollow rod-shaped bodies (1) and (1) on both sides. In addition, the strip-shaped non-slip material (3) also has a ridge portion (3a) having a circular cross section cut at the center in the width direction thereof, which is embedded in the groove (5) in the lower surface center of the hollow rod-shaped body (1), It is attached to the hollow rod-shaped body (1).

[0012] Thus, the hollow rod-shaped bodies (1), the strip-shaped connecting material (2), and the strip-shaped non-slip material (3) are formed by coextrusion molding the ABS resin and the soft vinyl chloride resin. And are integrally formed. Although not shown, the openings at both ends of each hollow rod-shaped body (1) are sealed by fitting a cap.

Since the hollow rod-shaped body (1) ... is made of ABS resin, the shutter-type bath lid having the above-mentioned structure is made as a whole in comparison with a normal bath lid using hard polyethylene or hard vinyl chloride resin for the hollow rod-shaped body. As the soft vinyl chloride resin of the belt-shaped connecting material (2) and the belt-shaped non-slip material (3) abuts the edge of the bathtub, it does not easily slip and is excellent. Moldability is obtained. Moreover, the ABS resin of the hollow rod-shaped body (1) and the soft vinyl chloride resin of the belt-shaped connecting material (2) have poor affinity, and even if they are integrally formed by coextrusion molding, the adhesion strength of the joint is not good. Although sufficient, in this shutter-type bath cover, the hollow rod-shaped body (1) and the band-shaped connecting material (2) are formed into the dovetail-shaped concavo-convex fit including the groove (4) and the ridge (2a). Since they are integrated by engaging with each other due to the mating structure, they do not peel off even if a repeated load is applied to the connecting part of both when winding and opening operation of the lid, and it has very excellent durability. To be demonstrated.

The groove (4) of the hollow rod-shaped body (1) is not limited to the inverted trapezoidal cross section as in the first embodiment, as long as the groove (4) has a wide shape, and the second embodiment shown in FIG. Various settings can be made, such as the cross-section cut-out circle as shown. Further, the bottom plate portion (12) of the hollow rod-shaped body (1) can be formed into a flat plate shape as a whole, for example, as in the third embodiment shown in FIG. 5, to form the groove (4) shallowly. In terms of strength, it is desirable to secure the wall thickness by providing the stepped portion (12a) bulging toward the inside of the hollow as in the first and second embodiments. Further, since the band-shaped non-slip material (3) does not have a load due to the winding and unfolding of the bath lid, instead of using the concavo-convex fitting structure as illustrated, the flat extrusion of the hollow rod-shaped body (1) is performed by coextrusion molding. The shape may be simply joined to the lower surface. Further, in this invention, it is also possible to adopt a configuration in which the band-shaped anti-slip material (3) is omitted.

[0015]

[Effect of device]

 According to the invention of claim 1, the shutter-type bath lid is excellent in heat resistance and strength as a whole, and the hollow rod-shaped body and the belt-shaped connecting material are made of a synthetic resin component which is hard to bond to each other. It does not come off even if a load is repeatedly applied to both connecting parts due to winding and unfolding operation due to use, so it exhibits extremely excellent durability, and the band-like connecting material has good moldability, and the lid is closed. It is provided with an excellent anti-slip function in the state.

According to the second aspect of the present invention, there is provided the above-mentioned shutter-type bath lid, which is excellent in the non-slip function particularly in the closed state.
