Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for automatically attaching and replacing a flat toilet seat cover made of woven fabric, nonwoven fabric, plastic, etc. to a toilet seat.

<Conventional technology and its problems> A toilet seat in which a stack of toilet seat cover papers is stored in the top cover of the toilet seat, and each paper is automatically taken out one by one and placed on the toilet seat when used. Cover automatic feeding bag'
A (Special Publication No. 1983-79618), 1. A plastic tube feeding device is placed near one end of the toilet seat, and 3. a plastic tube picking up device is placed near the other end. With the drive device of the device.

There is known an apparatus for attaching and replacing a cover tube to a toilet seat, which includes a switch connected to the cover tube, and the tube is moved by operating the switch. (
(Special Publication No. 57-29174) The disadvantage of the former type of toilet seat cover is that the cover slips off during the slightest movement of the toilet user, providing very limited sanitary protection. It only stops at the effect. On the other hand, in the latter case, the covering material used is practically a tube of plastic film, and the means for attaching the toilet seat to the toilet bowl is such that only one end of the horseshoe-shaped toilet seat is necessarily fixed to the toilet bowl due to its operating principle. , the entire toilet, including the other end, is installed in a free position above the toilet bowl.

Therefore, the force applied to the toilet seat, especially the lateral force, is concentrated on the attachment part at one end, making the seat unstable against side vibrations, and at the same time, this force is applied to the hinge structure including the attachment part. The tube-shaped cover material is pulled out from the tube feeding device by the drive of the pick-up device, and moves from the open end of the toilet seat, enclosing the toilet seat, to the other end of the toilet seat. The duplex is cut by a cutter at the attachment part of the duplex, and the dupe is torn through the attachment part and taken up by the pick-up device. Therefore, in order to reuse the used cover material, the means for forming it into a tube shape (e.g., adhesive sutures, etc.) must be omitted, and for this reason, in practice, disposable materials such as plastic film tubes are mainly used. The part of the toilet seat where plastic film is used is the part that comes into direct contact with human skin, and the plastic film has no hygroscopic properties and has an extremely smooth surface, which causes discomfort both visually and visually.

Furthermore, since the film tube is moved and exchanged only by the pulling force generated by the drive of the pick-up device, and the toilet seat is in the shape of a horseshoe, smooth movement cannot always be guaranteed.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-mentioned disadvantages and to provide a means for installing and replacing a new toilet seat cover.

<Means for solving the problems> In the present invention, as the toilet seat cover material, a band-shaped flat tissue cloth,
Non-woven fabric, electrostatically flocked or foamed plastic sheets, etc. are used, and the cover material is used repeatedly.9 To attach a toilet seat to a toilet bowl, fix both ends to the toilet bowl, and attach a seal to the back of the seat when the toilet seat is in use. The installation and replacement of the toilet seat cover, which is equipped with a supporting material that supports the applied load, is carried out using two endless belts equipped with a cover holder that runs a fixed length in a track installed on the back of the toilet seat using a drive device. The above-mentioned problems can be solved by actively moving the device around the circumference, installing it, and replacing it.

<Example> First, the present invention will be explained in principle. In Figure 1.2.3, the toilet seat cover 2 made of a belt-shaped woven fabric, etc., stored in a toilet seat cover supply bobbin (not shown) installed near one end of the horseshoe-shaped toilet seat 1, has a length slightly smaller than that in the middle direction. Guided by 3.3' of guide rollers provided at small intervals, the fourth
As shown in the figure, an endless belt 55 having a cover holder 4 is fed thereto. 5 of this endless belt
．． For example, as shown in Fig. 5.6, the toilet seat cover 2 is intermittently moved for a fixed length in the direction of the arrow by a pulley of different diameters driven by an electric motor or the like. This corresponds to the length from one end to the other, and the 5.5° of the endless belt runs while being restrained by the 6.6' track provided on the back of the toilet seat.
Since the toilet seat 2 has a horseshoe shape and the track 6 passes outside the 6° track, there is a difference in the length of each track. Therefore, it is necessary to provide a speed difference corresponding to the difference in length.

For this purpose, the pulleys are given different diameters. Thus, the cover 2 supplied to 5.5 of the endless belt is
Due to the supply angle and the tension of the cover 2, it is held by the holder 4 with its both ends slightly protruding, and is moved by the 5.5° travel of the endless belt. 5" and 5" of the endless belt are respectively 6 and 6° of a channel-shaped track made by extrusion of light metal or synthetic resin, etc.
As shown in Fig. 3, the toilet seat moves while being restrained in its running direction, and rotates 180 degrees while sequentially reducing the length in the middle direction from the end of the toilet seat.If the holder 4 is a needle as shown, the end of the toilet seat It is desirable that the pivoting angle is such that the needle passes through the cover 2 and is at right angles to the cover 2 in relation to the toilet seat.Due to this pivoting motion and advancing motion, the top surface and peripheral edge of the toilet seat are completely surrounded by the cover 2. . At this time, the holding tool 4 to 4°
The orbital position is set so that it remains constant over the length. Therefore, since there is no change in the tension of the cover 2, the frictional force with the toilet seat surface can be kept small, and the cover 2
The movement of the toilet seat L is extremely smooth.Next, the toilet seat L reaches the horseshoe-shaped curved part, and there is a difference in the inner and outer circumference lengths. In some cases, shrinkage occurs. Normally, the #lAR cloth used for cover 2 should be selected with this point in mind (it is necessary, but if you choose a material with a low elongation rate, cover it just before 3.3゜ of the 55' guide roller of the endless belt. The amount of supply of the cover 2 may be controlled by providing feed rollers 2 and 2. In this way, the cover 2 is moved with the toilet seat wrapped in it by the running of the belt 5. By the opposite operation, the cover 2 is unfolded into a flat shape, and the belt 5.5' is very easily rolled up by a winding device (not shown).
It is released from the holder 4 and wound up onto a suitable bobbin or the like in a flat state. The winding device is linked to the belt 5.5° drive device, and a new cover 2 is attached to the toilet seat 1, completing one cycle of cover replacement.9The important point in the present invention is that r! 74 For example, an endless belt can be analogized to the action of wrapping both ends of a piece of cloth over a picked object.
Retainer.

The track provided on the toilet seat is an essential element. Endless belts are flexible and durable, such as urethane rubber, reinforced with nylon or rayon cord, etc., or made of metal, etc., in the form of 1 chain or 2 strings, and the cross-sectional shape also has a track configuration. Various formats can be selected depending on the relationship. The holding device is not limited to the needle-shaped one shown in the example, but also has a structure in which a four-striped portion 8 is provided on the belt as shown in Fig. 7, and a cover 4 is inserted between this and a string 9 made of nylon or the like. In short, it is sufficient that the cover can be easily and securely held and released easily. Regarding the zero-order track, the track does not necessarily have to be channel-shaped or rail-shaped as shown in the example. The endless belt may be constructed by partially arranging rollers in series as long as it can correctly guide the belt with little friction. Therefore, although there are various situations in which the present invention may be implemented, a specific example of implementation will now be described. In FIGS. 8 and 9, a tricot pile cloth 11, such as a thin nylon crimped yarn, wound around a supply bobbin 12 used as a toilet seat cover material is attached to a pulley 7, which is driven by an electric motor operated by the operation of a switch (not shown). It is fed in a flat state to a 5.5° holder of an endless belt running with a 7° action. 13 is a guide roller for the cover material 11.0 The track 6.6' installed toward the back surface of the toilet seat 1 rotates while contracting in the track as described above, reaches the back surface of the toilet seat 1, and covers the top surface and periphery of the seat. Completely covered, it is transported in that state by the 5.5" endless belt and reaches the curved part of the second toilet seat. At the curved part, the cover material 11 located on the outside is stretched, but the fibers made of crimped yarn etc. In the case of woven fabric, this elongation can be fully accommodated. (You can also freely apply treatments such as preventing fraying to both ends of the folding bar material.) Furthermore, the cover material 11 is moved so that one end of the toilet seat has the other end. The endless belts 5, 5' rotate while gradually increasing the track width until reaching the winding portion, and the cover material 11 is HrMed into a flat shape.

This movement is completely opposite to that of the supply section. Cover material 1
1 is pulled in the direction of separation from the belt 5.5° by the winding bobbin 14 which is interlocked with the belt drive pulley 7.7°, and is very easily released from the holder and wound up in a flat state. Note that 15 and 15' have a well-known hinge structure that allows the toilet seat 2 to be lifted and rotated 90 degrees. At this time, a change occurs in the belt base, so in order to avoid this, a guide/tension pulley 16, 16' is provided. 17. 17' is a bolt to attach it to the toilet bowl, and 18 is a toilet bowl.

19 is a toilet seat support portion integrally molded with the toilet seat.

The operation of this device is at least the length of the visible range on the top of the toilet seat in - cycles, and by operating a switch, the used toilet seat cover is wound up on the winding bobbin 14 in the next operation, and a new cover is attached to the toilet seat at the same time. The movement of the toilet seat cover with it attached can be carried out smoothly since it is actively transferred over the entire circumference of the toilet seat. Further, in the present invention, since a woven cloth or the like is used as the cover material, the used cover material can be washed, disinfected, etc., and used repeatedly. Also, at this time, add fragrance to the cover material.

Deodorant, disinfectant impregnation, waterproof,! 9! Processing such as water processing 1
You are also free to add designs such as colors and patterns.

<Effects of the Invention> As mentioned above, the present invention completely improves all the shortcomings of the conventional technology and provides a toilet seat that is always clean and superior in terms of feel, texture, aesthetic sense, cleanliness, heat retention effect, etc. The covering material can be used repeatedly.

Installation and replacement operations are extremely smooth, and the strength of the toilet seat can be significantly improved.
