Description:
PORTABLE AND ADJUSTABLE CHILD POTTY

Description

Technical Field

[1] The invention generally relates to the field of child

potty used for potty training and for general use for children. The invention is also related to the field of portable potty that can be used by children as well as by adults.

Background Art

[2] A potty is an essential part in a child's care

device set, among other devices such as car seats, strollers, and toys. From the time children are potty trained a child uses a potty until they are able to use a standard toilet often with the use of a modified child seat for children. It is common for a child to develop a preference towards using a particular potty (i.e., of favorite color or one with the favorite cartoon character) at a particular age. Therefore a potty can become a part of the child care kit that travels with the child when traveling just like a car seat or a collapsible stroller.

[3] Portable potty is a useful tool for adults and

children, particularly while traveling. As an example, one could carry a portable potty for outdoor activities such as camping for the use of adults. With appropriate privacy attachments, a portable potty can be a very hygienic and desirable option when standard facilities are not available or limited, for example in areas such as parks or camping grounds.

[4] Prior art includes various portable potty inventions

which have major size and adjustability disadvantages compared to the invented Portable and Adjustable Child Potty.

Technical Problem

[5] The bulky size of existing potty products is a

major difficulty with the devices in the market at present. When a potty needs to be transported from a place to another, a fixed and large space is taken up by the device. For instance, for a family with two children, a 1 year old and a 3 year old as an example, two devices may need to be transported and each takes a fixed space and adds weight. If the travel involves air travel or outdoor, having to carry an extra volume of cargo and extra weight is a problem.

[6] Second issue with the current potty products is

their fixed size. As a child grows up, their height, body size, and weight change rapidly compared to an adult. As a result, multiple devices are needed to support the child at different ages. Typically, a smaller size is needed when the child is potty training and as they reach a certain age, the smaller device becomes unusable. It is not uncommon to see parents buying 3-4 potty of different sizes or standard toilet attachments of different sizes as a child grows up.

Technical Solution

[7] The invention addresses technical problems

associated with existing potty, namely the difficulty to transport due to their size and their inability to change size according to the user needs.

[8] The invented device consists of two main components

that are required for its use. These are the Adjustable Potty Chair Frame and the Potty Seat. The device may be used with two other optional components for added safety and functionality. These are the Pelvic Belt that can be used to fasten a child to the seat and the Activity Surface that can be used as a

drawing board or a support for reading or any other activity.

[9] The device has an Adjustable Potty Chair Frame that

is designed such that its height, width, and length (H, W, and L) can be adjusted. As an example, the H can be adjusted to 6", 10", or 12". The W can be adjusted to 8" x 8" or 12" x 12". The length can be adjusted to any setting in the W range as well. All of these adjustments can be made independent of the adjustments of the other two dimensions. For storage or travel, the frame can be retracted to a Travel Size of approximately 6"x6"x6" in H, W, and L as an example in one embodiment of the invention.

[ 10] Each member of the Adjustable Potty Chair Frame is

made out of hollow tubing of a particular shape such that a part of a member can collapse into a larger part of a member or expand out of a larger part of a member when the size is adjusted. The tubes may be made of Aluminum or similar lightweight material as an example. The locks and corner joints may be manufactured with a material combination such as metal and plastic. [1 1] The Potty Seat is designed such that its sides can

retract to make the part a smaller size for storage and transportation.

According to the teachings of this invention, the seat can be also modified such that it can be folded in half along its length. When in use with the

Adjustable Potty Chair Frame, the seat is set on the Adjustable Potty Chair Frame and the sides are fixed to the edge arms of the Adjustable Potty Chair Frame. The Potty Seat also has one or more retractable arms in the back and front that attach onto the back and front arms of the Adjustable Potty Chair Frame. To make it to Travel Size, the side flaps can be collapsed into the space under the Potty Seat ring. The seat may be modified such that a smaller flap retracts into a larger flap and then both of them can be retracted under the seat ring.

[12] The invented Child Potty is designed with an

optional Pelvic Belt can be attached to the Adjustable Potty Chair Frame such that a child can be fastened to the device in the seated position for safety purposes. In one embodiment of the invention, the belt is secured to three points in the Adjustable Potty Chair Frame, to the left and right back corners and the center point of the front arm. The belt can be opened at the center connector to place the child on the seat.

[13] The invented Child Potty can further include an

optional Activity Surface that can be attached to the armrests of the

Adjustable Potty Chair Frame such that a child may use it as a drawing board or a support for reading or any other activity. This attachment is also made such that it can be packaged to a smaller size by means of retracting one side into the other or by folding or by a combination of both. The underside of the surface is constaicted with web-like constaiction so that the load on it is distributed to the chair armrests with minimal or no sagging of the top surface. It is noted that this surface can also be constaicted as a foldable component similar to the Potty Seat constaiction.

Advantageous Effects

[14] The invention enables parents to use a single

potty for a child as the child grows up and offers great flexibility in home use as well as use while traveling. As the seat height, width, and length can be adjusted, the device can be used for a child as the child grows up.

Initially, it can be used at the lowest height (H) setting of 6" and the width and length (W & L) size of 10" x 10" for infant or older infant/young toddler potty training. As the child grows the height can be adjusted, for instance to 10" H for older toddlers and 12" H at even older ages such as 3-6 years etc. The W & L sizes can be increased as required over this growth period to 12" x 12" from the previous setting, so age and weight are not specifically attached to this potty.

[15] In case of using the invented device with multiple

children, the device can be used with children of multiple ages by adjusting W, L, and H settings between uses by the children of different ages. For instance, if the device is to be shared between a 1 year old and a 3 year old, W & L could be set to 10" x 10" for both of them and the H adjustment can be changed between 6" and 10" for the younger and the older respectively.

[16] The device may be used for a whole family during

travel and/or outdoor activities such as camping. As in the case of multiple children, the device dimensions need to be adjusted between the users and the bags be replaced. As the device can be packaged to the Travel Size, it makes it very convenient for transportation. For instance, for a camping excursion, only one small sized device need to be carried for the needs of the whole family. Because of the anti-roll and sturdy constaiction of the device base, it can be used even on loose soil (i.e., sandy soil or grass).

[29] Figure 13 are some example views of one embodiment

of the device with hollow tubing of circular cross section.

[30] Figure 1 shows the Adjustable Potty Chair Frame in

its maximum size setting (Left) and the Adjustable Potty Chair Frame in its smallest size which is also the Travel Size. At the maximum size of the particular embodiment shown, the frame is setup at 12" x 12" x 12" H, W, and L (Height, Width, and Length). At the minimum Travel Size, the same frame set to the size of ό'χό'χό'. The embodiment shown in Figure 1 shows 8 independent locks that can be used to secure the device at a particular setting. Four locks are used to set the height (H) of the device, two are used for length (L) setting, and two are used for the width (W) setting. Each of the locks can be operated by a single hand and both sides of the locks can be operated

independently. It is understood that number of locks and their placement can be modified to reduce the number of locks or by making some members

fixed/non-adjustable. Push-to-Release type locks are used in this embodiment. A lock can be released by pushing a designated part of the lock and with a released lock, one arm tube can be moved with respect to the other tube connected to the lock. It is noted that this particular lock type is used for illustration purposes only and other locking mechanisms may be used to achieve the same objective as these.

[31] Adjustable Potty Chair Frame can be made out of

tubing of different shapes and sizes. An example set of cross sections are given in Figure 2. It is noted that other sizes, shapes, thicknesses and such variations may be used for the same functionality without departing from the teachings of this invention.

[32] Figure 3 shows the Push-to-Release locking method

used in a particular embodiment of the invention. Two independent locks are attached to the ends of a fixed length Adjustable Potty Chair Frame member. By pushing a designated outside surface part/knob of the lock by a finger, a locking protaiding part is pushed away from the inside of the lock. This allows the inner tube to move with respect to the lock. Once the push is released, the locking protaiding part returns to its original position and locks the tube and lock in place.

[33] Figure 4 shows how an arm of the Adjustable Potty

Chair Frame is constaicted using the Push-to-Release locking method. In the given embodiment, a given Adjustable Potty Chair Frame member is constaicted using three tube parts. The tube with the Push-to-Release locking method has the largest cross section and the other two has smaller cross sections with one smaller than the other. When the Adjustable Potty Chair Frame is in Travel Size, the side tubes collapse to the inside of the tube with the

Push-to-Release locking method, effectively reducing the full length of the arm to the length of the tube with the Push-to-Release locking method.

[34] Figure 5 shows an alternative Lift-to-Release lock

that can be used instead of the Push-to-Release locking method. These locks may perform the same function as the Push-to-Release locking method and enable the device to operate as another embodiment of this invention. [35] Shown in Figure 6 is one embodiment of the Potty

Seat with adjustable extensions in all sides. In the Travel Size setting, all adjustable extensions can be pushed under the Potty Seat minimizing the size of the overall part. When used as a part of the Portable and Adjustable Potty, the Adjustable Potty Chair Frame is first set to a particular size and the

adjustable extensions of the Potty Seat are extended such that the size adjusted Potty Seat fits onto the top of the Adjustable Potty Chair Frame.

[36] Figure 7 is another embodiment of the Potty Seat

with adjustable extensions in three sides, a Potty Seat lid, and a foldable Travel Size configuration. In this configuration, wider adjustable extensions are located in the sides with another extendable part inside it. This enables the adjustable extensions to reach a wider width while not increasing the width of the Travel Size configuration. The back of this embodiment has two extendable arms, each similar to the adjustable extensions shown in Figure 6. In the Travel Size configuration, adjustable extensions are pushed all the way inside the Potty Seat, the lid is closed, and the whole unit can be folded in half. The mounting of this embodiment of the Potty Seat is similar to that shown in Figure 6.

[37] Shown in Figure 8 is a cross section of the Potty

Seat with the Disposable Waste Bag attached. As shown in Figure 8, the underside of the flaps are constaicted with web-like constaiction so that the load on it is distributed to the frame with minimal or no sagging of the top surface. The Disposable Waste Bag is attached using a ring that can hold the Disposable Waste Bag in place. The ring can be snapped in to the underside of the seat. After each use, the bag is closed immediately below the opening and the ring detached to remove the bag. Note that the back retractable arms are also shown in their Travel Size setting.

[38] Figure 9 shows the Adjustable Potty Chair Frame at

its maximum size setting with the Back Rest and Arm Rest attachments and the Potty Seat with adjustable extensions in all sides mounted in a read to be used state once the Disposable Waste Bag is attached. The adjustable extensions of the Potty Seat are extended to latch onto the Adjustable Potty Chair Frame.

Figure 10 shows two views of one embodiment of the

Activity Surface Attachment. The figure on the Right shows the cross section of the Activity Surface Attachment and the figure on the Left shows a 3D view of the Activity Surface Attachment in a ready to mount state. The optional Activity Surface can be attached to the armrests of the Adjustable Potty Chair Frame such that a child may use it as a drawing board or a support for reading or any other activity. This attachment is also made such that it can be

packaged to half its size by means of retracting one side into the other. The underside of the surface is constaicted with web-like constaiction so that the load on it is distributed to the chair armrests with minimal or no sagging of the top surface as illustrated in the cross section of Figure 10 (Left figure).

It is noted that this surface can also be constaicted as a foldable component similar to the Potty Seat constaiction.

[40] Figure 1 1 shows how one embodiment of the Portable

and Adjustable Potty Chair assembled to get the fully functional Child Potty. Note that mechanisms can be incorporated to secure the Potty Seat and the Activity Surface to the Adjustable Potty Chair Frame are not shown in the illustration in Figure 1 1.

[41] Figure 12 shows a special modification that can be

incorporated to the Adjustable Potty Chair Frame to add enhanced anti-roll capability. The corners of the Adjustable Potty Chair Frame can be made with a part that extends outwards from the frame and touches the ground surface on which the device is set. The modification on the front left corner to prevent forward roll is shown in Figure 12. It is understood that such modifications can be done to prevent forward-backward and left-right roll or any subset of this by altering the placements of the modifications. For example, by placing the modifications in the back legs only and extending outwards only (no extensions in left or right directions), backward roll resistance can be

enhanced.

Shown in Figure 13 are some example views of one

embodiment of the device with hollow tubing of circular cross section. It is noted that the seat shown with this embodiment is not adjustable and not foldable compared to the other embodiments described in the document. Figure 13 shows four different views of the device. Bottom right is the Adjustable Potty Chair Frame of the device at one H, W, and L setting. In the bottom left is the Adjustable Potty Chair Frame added with the Potty Seat and the Activity Surface Attachment. Top right shows another view of the same configuration. The top left shows the seat with a decorative covering and read to be used. This illustration is presented to show the versatility of the invented device to be manufactured in many different ways. As noted in the documents, variations shown in this document and other modifications obvious to one skilled in the art are considered within the scope of the teachings of this invention.
