Abstract

A buggy (pushchair, pram) which includes the use of a regular frame 1 and wheels 2 with a track 3 wrapped around the wheels 2. The track may be wrapped around extra tension wheels 4 and provided with extrusions 5 for increasing traction, and the buggy may include the use of a tilt mechanism 8 and a tilt applicator 9. The buggy may also utilize a folding mechanism 7 and be provided with a brake applicator 6 as on regular buggies. Safety cuffs 17 and shock absorbers (18, figure 8) may also be provided. The tracks allow the buggy to be pushed up and down steps and staircases.

Description

BUGGY TRACK NEW

The invention relates to a push-chair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) which includes the use of seat (or carrying pouchlplatform) which is mounted to a self supporting, free standing structure which utilizes the use of wheels for easy portability.

Such pushchairs are well known, but suffer from the disadvantage that, when the driver of the push-chair is confronted by obstacles such as steps and full flights of stairs, it is difficult or impossible to traverse such obstacles without needing the help of other people, such as passers by. When the push-chair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) obtains a passenger the load can be quite great, thus for the driver to carry the push-chair across such obstacles can be very difficult and best avoided, so the driver is forced to ask the help of other people such as passers by.

An object of this invention it to provide a pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) which allows the traversing of such obstacles such as steps and full stair cases (ascending and descending) easily and independently, without the need for the driver to obtain the help of other people.

Accordingly, this invention provides a pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) that includes the use of tracks around the wheels, to allow the easy ascent and descent of steps and full staircases (and other obstacles) without the driver needing the help of other people. It may also include the use of a tilt to allow easier access onto steps, and greater safety.

It may also include the use of a brake system which would increase friction during descending and ascending stairs and increase safety. This wheel brake mechanism can be attached to a brake applicator, which must be made in such a way, so it can be applied and released easily and quickly as and when the driver so chooses, including (but is not limited to) inside times of traversing obstacles, such as (but is not limited to) times of descending, or ascending, steps and full staircases.

All of this may be made in such a way as to allow the pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) to still be possibly foldable, for easy portability and storage, as is a common and necessary feature on today's pushchairs (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people).

Preferably the pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) would be made of metal or plastics material, or from a combination of these materials and the track may possibly be made of a rubber or plastic or a similar convenient material. There may still be tyres on the wheels made of rubber, or other suitable materials for added comfort.

A preferred embodiment of the invention will now be described with reference to the accompanying drawings in which: FIGURE 1 shows a possible side view of the whole pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people); FIGURE 2 is a section, which shows a possible front view of the front wheels of the pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people); FIGURE 3 also shows another possible side view of the whole pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people); FIGURE 4 is a section, which also shows a possible front view of the front wheels of the pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people); FIGURE 5 is a section, which shows another possible lower side view of the pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) with a possible tilt mechanism; As shown in Figure 1 the pushchair is composed of a regular frame 1 and wheels 2.

Figure 2 and Figure 4, both show different possibilities of how the lower front of the pushchair would appear. There is a track 3 which is wrapped around the wheels 2 in such a way as to provide good tension in the track. Additional wheels 4 may be present to help tension and motion in the track 3 and to help overcome obstacles. The track 3 may have extrusions 5 which help friction between tack 3 and traversing surface. The brake applicator 6 is positioned appropriately. It also shows a possible folding mechanism 7 which is of known design, and very common, Figure 8 also shows how the wheels 2 and additional wheels 4 may be laid out. Figure 8 also shows the possibility of shock absorbers 18 for extra comfort.

Figure 3 shows similar to Figure 1 but with a possible tilt mechanism 8 which is of known design and very common and tilt applicator 9 which is placed conveniently to be applied as and when needed. It also shows possible safety cuffs (safety restraints) 17 for added safety which are of known design and very common.

Figure 5 shows another possibility of how the tilt mechanism will work, using a simple pivot 10 and separation point 11 to allow more safety and comfort during descending stairs and full stair cases.

Figure 6 shows the tilt mechanism 8, with lower frame 12 (towards wheels) and upper frame 13 (towards handles) and main support pin 14 which passes through both the upper and lower frames 13+12 in such a way as to allow them to freely rotate about each other. The locking pins 15 keep the upper and lower frames 13+12 from freely rotating, but when the tilt applicator 9 is applied, the locking pins 15 are removed from their position to allow the upper and lower frames 13+12 to rotate freely about each other and obtaining the desired tilt to aid comfort and safety, especially when descending stairs. The locking pins 15 should have an automatic return mechanism 16 such as being spring loaded. Figure 7 also shows another possibility of how this could Due to the track 3, the pushchair can overcome obstacles such as ascending and descending steps and full stair cases without the driver needing the help of other people, by lying across multiple steps at once.

The tilt mechanism 8 (or 10 and 11) would allow the track 3 to tilt towards the direction of descending steps and full stair cases, without the upper frame 13 doing so.

Thus creating a more comfortable and safer condition for the baby and driver, whilst descending steps and full stair cases.

Claims

NEW CLAIMS1. A pushchair (buggy, pram, baby carriage and other similar devices that are used for carrying goods and people) which includes the use of seat (or carrying pouch/platform) which is mounted to a self supporting, free standing structure which utilizes the use of wheels, which have tracks wrapped around them to allow the traversing of obstacles including steps and full staircases easily and without the help of anyone else other than the driver, and could still have the possibility of a folding mechanism.
2. A pushchair as claimed in Claim I that also utilizes a tilt mechanism for increased safety when descending stairs.
3. A pushchair as claimed in Claim 1 or Claim 2 which may have extra wheels for increased tension and motion in the track and ability to overcome obstacles.
4. A pushchair as claimed in Claim 3 which also has a break mechanism to allow extra safety which can be applied as and when needed.
5. A pushchair as in any preceding claim which could also have the use of safety cuffs for extra safety, should the pushchair escape the grip of the driver.
6. A pushchair as claimed in any preceding claim which is made from metal, plastics materials, polycarbonates, rubbers or a combination of these materials.
7. A pushchair substantially as herein described and illustrated in the accompanying drawings.
