Abstract

This invention relates to a pet house. Whereas existing pet houses function by caging pets in, the present invention upgrades pet houses to a toy by installing lungs in the water with various additional functions. To achieve the above purpose, I suggest several methods. There are 2 ways to supply oxygen to the pet house; 1. to use an air suction pipe and an oxygen producer (or an air pump. The oxygen producer for this invention includes an air pump.) 2. to use buoyancy to supply air from the bottom. To keep this pet house from sinking under the water or floating on the surface of water, I suggest various methods using an up-and-down shifter, a buoyancy globe, and a string.

Description

The Pet Nest in Water Field of the invention

This invention relates to a pet house which can be used as a toy.

This water pet house, which can be used as a toy, is an upgrade and creates

a new view by installing lungs in water with various additional functions.

Background of the invention

In general, existing pet houses function by caging pets in.

Summary of the invention

To install a pet house in water, (1) oxygen should be supplied to pet and

(2) the balance of the pet house should be kept to overcome buoyancy. (3) To

upgrade its value as a toy, it should move freely in the water.

To supply oxygen in the pet house ; 1. Attach an air suction pipe to the pet

house to supply air (For further information, see the following detailed

description of the preferred embodiments.), 2. Use buoyancy to supply oxygen

from the water bottom to the pet house, 3. Attach a pipe or an oxygen

producer (or an air pump. The oxygen producer for this invention includes an

air pump.) to the main frame.

Also, I consider a type of main frame which lets smaller or the same amount

of air out of the supplied air as the air which the pet can breath in the

water and the balance in the water and transfer method through invention of

an up-and-down shifter utilizes the differences between water, air, and

buoyancy. One of main reasons for raising pets is for enjoyment and beauty. When using

this pet house in an aquarium, a new view of the harmony offish and land

animals can be created.

Also most of the existing toys are used on land, on the surface of the water and

in the air. But this kind of toy that works in the water has not been developed

well, so it is expected to create promising demands.

Detailed description of the preferred embodiments

1-1. Contents of the invention

This invention is to instaU a pet house so pets can breathe under water. To

upgrade it to a toy, it can move vertically and horizontally in water. To

achieve the above purpose, I suggest foUowing methods.

1-2. Main frame

Put pet inside the main frame and attach air suction pipe, oxygen producer

and up-and-down shifter outside.

The shape of the main frame on Fig.l is just an example and its shape

doesn't matter if the following conditions are satisfied.

As shown on Fig 1., if not equipped with a valve, it shuts water off at the

spot where extra air from general type closed main frame is exhausted, the

spot where the extra air is exhausted should be the same height or lower

than the pet's footstep (See Fig. 10, It doesn't matter if a water valve is

equipped).

As shown on Fig 11, an example of a different shape of the main frame, the

bottom is opened and the upper part is closed. As in Fig 1, a general closed

main frame, the pet's footstep should be the same height or higher than the highest position of the main frame.

Here I review how to supply air into the water pet house whose maitj frame is

opened on the bottom as foUows. Air can be suppUed by attaching an oxygen

producer (or air pump) to the pet house directly in the water or by using a

hose through an oxygen producer (or air pump). Also in the case of an oxygen

producer or an air pump for the pet house at a certain distance (not

connecting with even a hose), air can be suppUed to the water pet house

using the buoyancy and gravity difference between water and oxygen. When

observing the air stream from an oxygen producer which is separate from the

pet house, air full of oxygen has potential energy in the water and moves up

like the soUd line of Fig. 12. When air moving in upwards direction arrives

at the water level of the pet house whose main frame is opened on the

bottom, the prior potential energy is changed to kinetic energy rushing into

the main frame with an opened bottom at a high speed and filling the pet

house with air by pushing the exhausted air out toward the same direction of

the dotted line of Fig. 12.

Repeating this cycle, fresh air is consistently suppUed to the pet house.

The highest position of the main frame with an opened bottom and the

position of the general main frame where its extra air is exhausted (The

hole depends on the suppUed air, but it should be larger the size that the

same amount of air as the suppUed air can go through immediately.) should

be strictly sealed so water and air can't escape. Or a small hole (for a better air stream) can be made for discharging only smaUer amounts of air

than the suppUed air (or exactly the same amount). In this case, if smaller

or the exactly same amount of air can be released through the highest

position of the main frame with opeti bottom or a smaU hole (or holes) where

the extra air of a general main frame is exhausted, water can't go up to the

pet's footstep of the main frame.

As shown in Fig. 14, oxygen(air) consistently in the main frame by attaching

a pipe on the main frame or putting a pipe in the main frame, water can't go

into the main frame as the air pressure gets higher in the main frame. For

the main frame with opened bottom, water can't go into the lower position

(it is only a few mm, though) than the highest position of the main frame

with opened bottom as the air is released in a lower direction (like the

dotted arrow, No. 24) and the water is pushed by the air on the main frame

with opened bottom.

Of course it depends on how strongly air pushes onto the inner main frame,

but without a water shutting vale, the size of the position where the extra

air exhausts should be somewhat smaUer. At this time, the footstep can be

installed on the lower spot for the highest position on the main frame with

open bottom and a hole where extra air exhausts on the general type closed

main frame. Especially for the closed type general main frame, no water

flows into the bottom, (though a water shutting valve is not equipped.) This

method can be used for expanding the inner space in the main frame, but to use this method, special care is required as the water can go into the

closed type main frame or go up to the highest position of the main frame

with opened bottom and the pet can get wet if its air supply is disconnected

or weakened for a short moment.

There is a structure with partly opened bottom which is a modification of a

main frame with opened bottom and air can be suppUed at a certain distance

from the bottom or laterally. In this case, as shown on Fig 15, the closed

bottom part can be lower than the pet's footstep or can be higher like Fig.

15 B, or it can be at the same level. As Fig 15, A shown, in case the bottom

of pet house is lower than the opened part, if there's a low siU beside the

opened bottom part keeping the air pressure in the main frame, water doesn't

go into the lower position of the pet's footstep. (Fig 15, A shows a high

sill and in this case, a footstep should be instaUed for pets to pass

through the opened part.) fn the case of not having a sill, water doesn't go

into it if the size of the opened part is smaU enough and strong air

pressure is consistently kept.

For the pet house with partly opened bottom, shown as Fig. 15, A, a smaU

hole such as No. 29 of Fig. 15 is required to raise the mobiUty of air and

to consider that pet can be put on a lower position than the water level of

opened bottom part. Except this point, its working principal is the same as

the pet house with fully opened bottom.

(In the case of a higher siU shown as Fig. 15 A, its necessity is stronger.) Also a smaU hole such as No. 29 on the Fig. 15 is located higher than the

water level in the pet house. In case the way to the main frame is narrow as

shown on the Fig. 15, the air inlet (can be same as the water level in the

main frame of the pet house) can be the same size as the pet house floor or

can be larger. Fig. 16 can be considered as a modification of Fig. 15, A

and in the case of Fig. 15, B, an expansion modification is possible. The

reason why structures such as Fig. 15 and Fig. 16 which are the main frame

with a partly opened bottom are needed is to prevent pbt's waste going into

the water by separating water and pet.

2. How to supply pet air

A. Using an air suction pipe (See Fig. 3)

The pipe connecting the main frame of the pet house and air outside the

water surface (See Fig 6 & 7.) can connect a buoyant globe to the main frame

of the pet house(See Fig 6 & 8.).

B. Using an oxygen producer (See Fig. 4)

InstaUed under the main frame of the pet house, an oxygen producer suppUes

air to the pet house (See Fig. 8). Also it supplies air to the following

up-and-down shifter, sinking the main frame of the pet house instead of a

gravity sinker. (See Fig. 8)

3. How to sink the pet house in the water

A. Using a gravity sinker (See Fig. 4)

A gravity sinker is made of metal whose specific gravity is higher than water. The main frame of the pet house can be made of materials with high

specific gravity, but in this case, portabiUty of the pet house gets lower.

When attaching a gravity sinker under the main frame of the pet house (See

Fig. 6), the pet house sinks. An oxygen producer made of materials with high

specific gravity can replace it. (See Fig. 8.)

B. Using a string (See Fig. 7)

Hang a string on the floor or right/left waU to place the pet house in the

adequate depth of water.

4. Balancing of the pet house in the water at an adequate depth

A. Using the up-and-down shifter

As the specific gravity of air is lower than water, air goes up when water

is mixed with air in a closed space and air pressure gets higher, pushing

water out, when air quantity gets larger. The Up-and-down shifter is used to

manipulate these characteristics of air.

For reference, the amount of water in/outlet and air outlet of an

up-and-down shifter does not matter, but the height difference of the water

in/outlet and air outlet does.

Here is an explanation about an up-and-down shifter with one in/outlet and

one air outlet

(1) As a basic type shown on Fig. 5, there can be an up-and-down shifter

with 2 holes for a water in/outlet and an air outlet. As shown in the Fig,

the air outlet should be higher than the water in/outlet. When working, the up-and-down shifter produces power which overcomes air pressure and water

pressure by installing a motor on the water in/outlet or the air outlet for

strengthening the discharge of water or air and absorbabiUty of water. It

can be moved though the height of the air outlet and the water in/outlet is

the same or the higher than the air outlet as a result of structural change.

Here is how to work of the up-and-down shifter on Fig 5.

First, connect an up-and-down shifter to an oxygen producer and attach it to

the pet house. If the pet house is too tight and floats because of its

buoyancy, open an air exhaust valve. As the water pressure of the water

in/outlet in the low position is higher than the water pressure of the air

outlet on high position, water can enter into the up-and-down shifter from

the water in/outlet. Then the air is vented through the air outlet as the

inner pressure of the up-and-down shifter gets higher. Therefore the pet

house sinks as the up-and-down shifter filled with water gets heavy.

Contrarily, when the pet house is too heavy and sinks, shut the air outlet

with the air exhaust valve and inject air into the up-and-down shifter. As

the air with lower specific gravity fiUs the upper up-and-down shifter, the

air pressure inside the up-and-down shifter gets higher and overcomes the

water pressure. Then the up-and-down shifter gets tighter and floats as

water is pushed into water in/outlet.

(2) Bladder type up-and-down shifter

- Shut water as main frame or up-and-down shifter doesn't contact water (Air can be contacted or not), and adjust the buoyancy by adjusting the size of

main frame or up-and-down shifter. When the main frame or up-and-down

shifter isn't contacting water and set with the adequate center of gravity

(Can float or sink with tittle weight difference), the pet house floats as

the up-and-down shifter or main frame gets bigger and its buoyancy gets

higher. Contrarily when the up-and-down shifter or main frame gets smaller

and its buoyancy gets lower, the pet house sinks. To adjust the size of the

main frame or up-and-down shifter, various methods are used such as folding,

inserting and blowing up with air.

For example in the case of Fig. 9, the buoyancy is changed by adjusting the

size of main frame in an inserting way. For the working process of Fig. 9,

there is a hole for air exhaust (See Fig. 1) and a water valve on the main

frame (It is the same as the up-and-down shifter.) as shown on Fig. 1. When

air pressure in the main frame or up-and-down shifter gets higher by

reducing the volume, inner air goes out through the hole. In the case of

mamtaining a certain status, water can't flow inside the main frame or

up-and-down shifter as water pushes the water shutting valve outside (Water

pressure occurs.)

When expanding the volume of the main frame or up-and-down shifter, for the

outside water shutting valve, internal draw-in power acts by air pressure

and external water shutting valve pushing power acts by water pressure as

inner air pressure gets lower. Therefore water can't flow inside the main frame or up-and-down shifter

At this time, if supplying air in the main frame or up-and-down shifter from

an oxygen producer, the volume can be easily increased.

However if the up-and-down shifter is not in contacted with water, it can

work with the elasticity of air volume. (In this case, the capacity of the

up-and-down shifter gets lower, but the structure is more simple without an

air outlet or air exhaust valve.)

(3) Up-and-down shifter with opened bottom

Same as the main frame, an up-and-down shifter can have an opened bottom.

Like other up-and-down shifters, this capacity condition (When the up-and-down

shifter is blown to the utmost - See Fig. 13.) represents the amount of water

which makes a level with the highest position of the below frame of an up-and-

down shifter with opened bottom going into the inner up-and-down shifter above

and showing weight adjustment capabiUty of the up-and-down shifter with

opened bottom.

(Specific gravity of water is 1.)

To move an up-and-down shifter with opened bottom, as Fig 13 shows, move

the side wall like the arrow 27, or adjust the amount of air going into the up-and-

down shifter by adjusting the whole volume of the up-and-down shifter

horizontally like the arrow 26 above the up-and-down-shifter with opened

bottom. (When moving some parts which make a gap verticaUy not moving the

entire parts at once, the highest position of the moved waU side makes a level with water and cage air inside. - Of course you can move the entire parts.)

Applying the working process of the up-and-down shifter with opened bottom to

a main frame with opened bottom of Fig. 11, it can be used as an up-and-down

shifter.

> B. Using a buoyant globe

A buoyant globe is a device for having more buoyancy with an empty tube,

hemisphere (See Fig. 2) or sphere. A buoyant globe prevents the pet house

from sinking to the bottom by a gravity sinker. When using an oxygen

producer as a gravity sinker (See Fig. 8), use a buoyant globe with a closed

o inlet. In other cases, open the inlet and vent with air suction pipe. (See

Fig. 6)

C. Using a string

In the case of fixing the bottom or waU (See Fig. 7) using a string, the

pet house can be situated at the appropriate height in the water by the

5 adjusting length of the string.

D. To calculate the weight of the pet and pet house exactly, it can be in

the water balanced with the buoyancy.

5. Transfer of pet house

A. Vertical Transfer

o The pet house can be moved up and down by adjusting an up-and-shifter.

B. Horizontal Transfer

(1) Using an oxygen producer As shown on Fig. 8, air from an oxygen producer is released through the

right hole and the exhausting power acts as thrust.

(2) Using a motor

Using a motor, the pet house can be moved horizontally.

Claims

What is claimed is:

1. A detachable pet house for pets to live in water or an aquarium.

2. The pet house is attached to an air suction pipe on the main

frame to supply pet air.

3. An up-and-down shifter (In case of using by modifying a main frame and

including a bladder

type up-and-down shifter and an up-and-down shifter with opened bottom)

As the specific gravity of air is lower than water, air goes up when water

is mixed with air and air goes in a upper direction and this up-and-down shifter

is used to manipulate these characteristics of air.

As injecting water into the up-and-down shifter, air pressure gets higher pushing the water outside up-and-down shifter. When the up-and-down shifter

gets tighter, it rises as buoyancy is bigger and gravity is lighter. Contrarily the

air is let out in the up-and-down shifter, it descends. When water can't contact

with the main frame or up-and-down shifter,

4. The highest position of the main frame with opened bottom and the position of

general main frame where its extra air is exhausted should be strictly sealed

and water and air can't be contacted with outside through those positions. Or a small hole (for a better air stream) can be made for discharging only smaller

amount of air than the supplied air (or exactly the same amount) to keep air for

pet breathing in the water.

5. Installing an oxygen producer (or an air pump) laterally or under the main

frame or an up-and-down shifter separating from them, air from the oxygen

producer (or an air pump) is supplied to the pet house whose main frame and

up-and-down shifter with opened bottom using buoyancy.

6. As attaching an oxygen producer (or an air pump) to the main frame of pet

house which can be closed type or opened type directly, oxygen (air) is

supplied into the main frame directly.

Or putting a pipe hi the main frame (See Fig. 14), oxygen (air) is injected into

the main frame and is supplied to pet directly.
