Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sealing device for sealing dust, human waste, and the like.

[0002]

[Prior art]

 As a device of this type, there is a simple toilet as shown in FIG. In this simple toilet, a vinyl tube 101 is folded in an annular shape, the tube 101 is arranged around a funnel type tubular body 102, and the tube 101 is guided from above the tubular body 102 to below. Below the cylindrical body 102, a pair of holding plates 103 is provided, and the tube 101 is held between the holding plates 103. A heater is provided on the edge of each holding plate 103. These heaters are temporarily heated to weld the tube 101 and seal the tube 101.

Two sets of rollers 104 and 105 are arranged below each holding plate 103. The pair of rollers 104 on the right side sandwiches the right edge of the tube 101, and the pair of rollers 105 on the left side sandwiches the left edge of the tube 101.

Here, when the excrement falls from the toilet seat 106 to the inside of the tube 101, the excrement is collected at the sealing part of the tube 101, that is, the part of each sandwiching plate 103. In this state, when the pedal 107 is depressed, in response to this, the holding plates 103 are opened, and two sets of rollers 104 and 105 rotate to pull down the tube 101. The pulling down of the tube 101 is performed until the human waste inside the tube 101 comes to the lower side of each holding plate 103. After that, the sandwiching plates 103 are closed, and the heaters of the sandwiching plates 103 generate heat to seal the tubes 101. Therefore, the human waste inside the tube 101 is sealed between the two upper and lower sealing sites.

Such a process is repeated, and the tube 101 in which human waste is sealed is stored in the container 108.

[0006]

[Problems to be solved by the device]

 However, in the above-mentioned conventional apparatus, since the tube 101 is sealed in a state where the tube 101 is inflated, a large amount of air is sealed inside the tube 101 together with the human waste. As a result, the used tube 101 became bulky, and the container 108 for storing the tube 101 soon became full. Further, when a large amount of air is sealed inside the tube 101, it becomes difficult to process the tube 101, that is, to collect the tube and incinerate it.

Further, since the tube 101 is heated and welded by the heater, a facility for supplying electric power is required, and the installation place of this toilet is limited.

Therefore, an object of the present invention is to provide a sealing processing device capable of sealing the tube while expelling the air inside the tube.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, a sealing member in which a tube made of a flexible sheet is pulled up by hand and folded in an annular shape, an introduction frame arranged in the center of the annular sealing member, and an introduction frame The cam has a pair of cams arranged in parallel below the frame, and each cam has a column portion that is axially supported and a plurality of blades that radially protrude from the column portion.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a main mechanical section 1 according to one embodiment of the present invention, and FIG. 2 shows the main mechanical section 1 partially broken away.

In the main mechanism portion 1, a first cam 11 and a second cam 12 are supported between the two support plates 10a and 10b. Both ends of the shaft 13 of the first cam 11 are inserted into the small holes of the support plates 10a and 10b, so that the first cam 11 is rotatably supported. Further, both ends of the shaft 14 of the second cam 12 are inserted into the long holes 15a and 15b of the support plates 10a and 10b, respectively, so that the second cam 12 is rotatable and moves along the long holes 15a and 15b. Supported as possible.

Both ends of the shaft 13 of the first cam 11 and both ends of the shaft 14 of the second cam 12 are connected by two coil springs 16. These coil springs 16 attract the movable second cam 12 to the first cam 11 side.

The drive shaft 17 is rotatably supported by the support plates 10a and 10b. A lever 18 is fixed to one end of the drive shaft 17, a coil spring 19 is fitted to the other end, and a fan gear 21 is fixed to the other end. The sector gear 21 meshes with an interlocking gear 22 fixed to the end of the shaft 13 of the first cam 11.

FIG. 3 schematically shows the main mechanical section 1 as viewed from the side. As is apparent from FIG. 3, one end 19a of the coil spring 19 is hooked in the recess 21a of the sector gear 21, and the other end 19b of the coil spring 19 is hooked in the protrusion 23 projecting inward from the support plate 10a. ing. The coil spring 19 biases the fan gear 21 in the direction of arrow A until the fan gear 21 contacts the protrusion 23.

When the lever 18 is rotated in the direction of arrow B, the sector gear 21 also rotates in the same direction, and the interlocking gear 22 and the first cam 11 rotate in the direction of arrow C. Along with this, the second cam 12 rotates in the direction of arrow D.

Thereafter, when the lever 18 is released, the elastic force of the coil spring 19 causes the fan gear 21 to rotate in the direction of arrow A until it comes into contact with the protrusion 23. Along with this, the lever 18 also rotates in the same direction and returns to the original position. At this time, the interlocking gear 22 rotates in the direction opposite to the arrow C, but the first cam 11 does not rotate and remains stopped, and the second cam 12 also stops.

Therefore, only the rotation of the interlocking gear 22 and the shaft 13 in the direction of the arrow C is transmitted to the first cam 11, and the rotation in the opposite direction is not transmitted. In order to transmit only the rotation in one direction, for example, a one-way clutch is built in the first cam 11, and the first cam 11 is connected to the shaft 13 via the one-way clutch. Further, the ratchet mechanism applied to the micrometer may be applied.

FIG. 4 shows the first and second cams 11 and 12. As shown in FIG. 4, the first and second cams 11 and 12 have a substantially star-shaped cross-section and mesh with each other.

The first cam 11 includes a pillar portion 24 through which the shaft 13 penetrates, five blades 25 radially protruding from the pillar portion 24, and rubber attached to the ends of these blades 25. Each elastic band 26 made of the same and each cover 27 at both ends of the first cam 11 are provided, and as described above, only the rotation of the interlocking gear 22 and the shaft 13 in one direction is transmitted to the first cam 11. On the other hand, a one-way clutch is built in the pillar portion 24.

In a substantially similar manner, the second cam 12 includes a pillar portion 28 through which the shaft 14 penetrates, five blades 29 radially projecting from the pillar portion 28, and end portions of these blades 29. Each elastic band 31 made of rubber attached and each cover 32 at both ends of the second cam 12 are provided.

Since the second cam 12 is attracted to the first cam 11 side by the coil springs 16 as described above, the wing plate of one cam is located between the two wing plates of the other cam. The first and second cams 11 and 12 mesh with each other. Therefore, when the first cam 11 rotates in the direction of arrow C, the second cam 12 rotates in the direction of arrow D.

Now, the main mechanism section 1 is incorporated in a simple toilet 51 as shown in FIG. 5, for example. The simple toilet 51 is an example of the sealed processing device of the present invention.

In this simple toilet 51, a partition plate 53 is provided inside the support housing 52, and the main mechanism section 1 is disposed below the partition plate 53. A hole 53a is formed in the partition plate 53, and the first and second cams 11 and 12 of the main mechanism portion 1 are located under the hole 53a.

The lever 18 of the main mechanism unit 1 is extended to the outside of the support housing 52 and is passed through a frame frame 54 fixed to the wall of the support housing 52. The frame frame 54 limits the rotation angle of the lever 18.

A toilet 55 is provided on the periphery of the hole 53 a of the partition plate 53 in a protruding manner. An annularly folded tube 56 is arranged on the partition plate 53, and the toilet 55 is located at the center of the annular shape. From above, the toilet cover 57 is covered.

The tube 56 is made of a synthetic resin thin sheet, and the tube 56 is folded in an annular shape by pulling the tube 56 by hand.

A storage housing 58 is provided below the support housing 52. The housing 58 has a drawer 59. A hole 58a is formed in the upper plate of the housing 58, and the first and second cams 11 and 12 of the main mechanism portion 1 are located on the hole 58a.

FIG. 6 shows the simplified toilet 51 as viewed from the side. As is clear from FIG. 6, the annularly folded tube 56 passes through the inner periphery of the toilet 55, is guided to the main mechanism portion 1 via the upper peripheral edge of the toilet 55. Then, the tube 56 passes between the first and second cams 11 and 12 of the main mechanism portion 1, reaches the drawer 59 of the housing 58, and is stored therein.

Next, a procedure for using this simple toilet 51 will be described.

First, one end of the tube 56 is pulled out upward from the periphery of the toilet 55, and this end is sealed. The tube 56 can be sealed, for example, by tying a knot in the tube 56. Further, an adhesive may be used, or the tube 56 may be tied up with a string.

One end of this tube 56 is guided through the inside of the toilet 55 between the first and second cams 11 and 12 of the main mechanism portion 1, the lever 18 is rotated in the direction of arrow B, and the first cam 11 is moved to the arrow C. The second cam 12 is rotated in the direction of arrow D in the direction of arrow D. As a result, one end of the tube 56 is guided to the drawer 59 of the housing 58 through the space between the first and second cams 11 and 12.

After that, when the toilet 51 is used up, the human waste 61 is collected inside the tube 56 as shown in FIG. 7A. At this time, the wing plate 25a of the first cam 11 faces the column portion 28 of the second cam 12 and the second cam 12 is biased toward the first cam 11, so that The elastic band 26a of the blade 25a of the cam 11 is pressed against the column portion 28 of the second cam 12 via the tube 56. As a result, the tube 56 is sealed between the blade 25a of the first cam 11 and the column 28 of the second cam 12, and the human waste 61 is collected above the sealed portion.

A groove is formed at the center of the elastic band, so that the tube is tightly sandwiched between the elastic body and the column portion to reliably seal the tube.

In this state, when the lever 18 is rotated in the direction of arrow B, the first cam 11 moves in the direction of arrow C, as shown in FIGS. 7 (b) and 7 (c). The two cams 12 rotate in the directions of arrows D, and the tube 56 between the first and second cams 11 and 12 is pulled down.

Since the blades 25 of the first cam 11 and the blades 29 of the second cam 12 mesh with each other, the human urine of the tube 56 is crushed and the empty space of the tube 56 is crushed. The tube 56 is pulled down while pushing out the air. Therefore, the tube 56 led out under the first and second cams 11 and 12 contains almost no air but only human waste.

When the lever 18 is rotated until it comes into contact with the frame frame 54 of the support housing 52, the blade 25 a of the first cam 11 faces the pillar 28 of the second cam 12 and the blade 25 b of the next cam 25 b is moved. The first and second cams 11 and 12 rotate until the next blade 25c faces the pillar 28 after the blade faces the pillar 28. That is, one operation of the lever 18 causes the first cam 11 to rotate by an angle from the blade 25a to the blade 25b to the blade 25c, and accordingly, the second cam 12 rotates by the same angle. To do. As a result, as shown in FIG. 7D, the human waste of the tube 56 is completely guided to the bottom of the first and second cams 11 and 12.

When the rotation of the first and second cams 11 and 12 is completed, the blades 25c of the first cam 11 face the pillar portion 28 of the second cam 12 via the tube 56, and the tube is here. 56 is sealed. As a result, the human waste is sealed in the tube 56, and the human waste and its odor do not leak from the tube 56.

After that, when the lever 18 is released, the sector gear 21 rotates in the direction of arrow A by the elastic force of the coil spring 19 shown in FIG. 3 as described above, and the lever 18 returns to the original position. Along with this, the interlocking gear 22 and the shaft 13 rotate, but this rotation is not transmitted to the first cam 11, and the first and second cams 11 and 12 remain stopped. Therefore, the state shown in FIG. 7D is maintained.

Similarly, every time the toilet 51 is used again, the lever 18 is rotated in the direction of the arrow B, and together with the tube 56, the human waste of the tube 56 is pulled down, and the human waste is collected in the tube. It is sealed at 56.

As described above, in the main mechanism portion 1, the first and second cams 11 and 12 are engaged and rotated, and the tube 56 between the first and second cams 11 and 12 is pulled down while the inside of the tube 56 The air is pushed out and only the human waste is sealed in the tube 56.

FIG. 8 shows a modification of the main mechanism section. Here, a pedal 62 is fixed to one end of the drive shaft 17 instead of the lever 18 shown in FIG. 1, and a large diameter gear 63 is fixed to the other end of the drive shaft 17 instead of the sector gear 21. . Further, a small diameter gear 64 is interposed between the large diameter gear 63 and the interlocking gear 22, and the small diameter gear 64 is rotatably attached to the support plate 10a.

With such a configuration, when the pedal 62 is depressed and the pedal 62 is rotated in the direction of arrow E as shown in FIG. 9, the large diameter gear 63 also rotates in the same direction, and the small diameter gear 63 rotates. 64 rotates in the direction of arrow F, and the interlocking gear 22 and the first cam 11 rotate in the direction of arrow C. As a result, the tube between the first and second cams 11 and 12 is pulled down.

After that, when the pedal 62 is released, the pedal 62 is pulled up by the coil spring 65 hung between the pedal 62 and the support plate 10b to return to the original position. Along with this, the large-diameter gear 63 and the small-diameter gear 64 also rotate in reverse, but the first and second cams 11 and 12 remain stopped.

FIG. 10 shows another modification of the main mechanism section. In this main mechanism portion, a pedal 66 is provided instead of the lever 18 shown in FIG. The pedal 66 is directly connected to the sector gear 21, and the pedal 66 and the sector gear 21 are integrated. When the pedal 66 is depressed, the fan gear 21 rotates, the first cam 11 rotates in the direction of arrow C, the second cam 12 rotates in the direction of arrow D, and the tube is pulled down. When the pedal 66 is released, the pedal 66 returns to its original position due to the elastic force of the coil spring 19.

In the embodiments described so far, the cam having five blades is illustrated, but the number of blades may be increased or decreased. Further, the shape of the wing plate may be appropriately changed.

Further, a motor may be used to rotate each cam. In this case, an electric power facility is required as in the conventional device shown in FIG. 10, but the present invention is based on the point that the tube is sealed while expelling the air inside the tube. Clearly, the device of this invention is superior.

Further, the sealing apparatus of the present invention can be used not only for sealing human waste but also for sealing various things such as kitchen garbage and hospital waste.
