JPS6036155Y2 - Bath water surface cover for quick boiling - Google Patents

Description

[Detailed Description of the Invention] (Purpose of the Invention) The present invention relates to a hot water surface type that is always adaptable to rapid boiling of a bath, regardless of slight changes in the size of the bathtub, and is also foldable.

(Prior Art) Conventionally, in order to quickly boil a bath, a hot water surface mold 1a made of a foamed resin plate as shown in FIG. 1 has been used.

Since this board is cut to a predetermined size, it cannot be changed to a color that matches the size of the bathtub.

Therefore, there are many types of hot water surface types 1a depending on the size of the bathtub.
had no choice but to hold.

Moreover, since it is a wide single board, it requires space to carry and store, which is inconvenient.

(Structure of the invention) The present invention consists of a frame body in which elastic main ribs are attached radially to the support tube of the joint part consisting of the engagement frame and the support tube, and a heat-resistant vinyl sheet is stretched between the main bones and the sheet. It is characterized by continuously reinforcing the ends with heat-resistant edge material to form an inverted bowl shape.

Next, an embodiment of the hot water surface mold according to the present invention will be explained with reference to the drawings. In FIGS. 2 and 3, an engaging frame 2 having a projection piece 1
is removably inserted into the support tube 3, and around the support tube 3, four steel main ribs 4 of equal length are attached via hinges 5 in a radial manner according to the size of the bathtub so that they are in symmetrical positions. Attach to.

Further, a steel tension rib 6 is attached to the lower part of the engagement frame 2 via a hinge 7, and the other end of the tension rib 6 is connected to a hinge 8 provided in the middle of the main rib 4 to form a frame body 9. .

Furthermore, a handle 10 for attachment and detachment is attached to the upper part of the engagement frame 2.

The thus formed frame 9 is covered with a heat-resistant vinyl sheet 11 stretched along the main frame 4, and the four corner ends of the main frame 4 and the edge of the sheet 11 are covered with heat-resistant edge material 12. The connection is reinforced to form an inverted bowl-shaped hot water surface A that expands into a rectangular cross-section with a shallow depth.

(Function of the device) In Fig. 2, the handle 10 is pulled upward, the engagement frame 2 is inserted into the support tube 3 and connected by the projection piece 1, and the main rib 4 is turned into an inverted bowl shape by the extension of the tension rib 6. Shows expanded state.

Now, put this hot water surface type A into the bathtub 13 as shown in Figure 4.
4, since the main rib 4 has elasticity, it bends and the periphery of the hot water surface mold A can be expanded and contracted, so that the bathtub 13 can be tightly attached as the size of the bathtub 13 changes.

Also, since it is in pressure contact with the surroundings of the bathtub, it will not tilt or overturn.

After this, if you put the lid 15 on the bathtub and boil it, the water surface 14 will rise because the coating of the hot water surface type A is made of the heat-resistant vinyl sheet 11.
It goes without saying that quick boiling is possible without the vapor dissipating.

Also, when storing this hot water surface mold A, by retracting the projection piece 1 and pulling out the engaging frame 2 below the support tube 3, the tension ribs 6 and main ribs 4 close and fold as shown in FIG. It becomes like an umbrella.

(Effect of the invention) In this case, a heat-resistant vinyl sheet with no air permeability is stretched over a frame made of an elastic main frame that can be folded freely, so when the frame is expanded to form an inverted bowl shape, the hot water level is The ring is expandable around the circumference, allowing for a tighter fit as the bathtub size changes and faster boiling.

Moreover, when storing, it can be easily folded by operating the engaging frame, which has a great effect on saving materials, simplifying handling, and saving storage space.
