DESCRIPTION

AUXILIARY DEVICE TO FACILITATE THE DISPLACEMENT OF BABY AND SIMILAR CQCHES ON STAIRS, ARENQSAS SURFACES, SNOW Q

SIMILAR.

TECHNICAL SECTOR

The present invention relates to an auxiliary device to facilitate the movement of baby cars, strollers and the like through some irregular surfaces such as stairs, sand or snow; thus being located in the field of manufacturing devices and filming parts especially for baby cars, driven by human traction. This system turns out to be a system applicable to almost all configurations of cars or baby carriages and facilitates not only the transportability of the vehicle but the safety of the occupant, being in this case a baby.

BACKGROUND OF THE INVENTION

There are records and patents registered for artifacts and devices, being similar in terms of their function as it is to facilitate the movement of the baby car on irregular surfaces such as stairs, or for snow and sand, aimed at increasing the contact surface between the baby cars or chairs and the surface on which they are moving.

A history registered in the US as US 5427390 A, by Scott Duncan and A. Lisson, contemplates a system consisting of a ski accessory and a single fixing element to be operatively mounted on a wheel of a wheeled vehicle, such as a baby carriage. The ski accessory comprises a generally elongated and flat channel portion and front and rear portions turned upwards. The unique fixing element has a first and a second cooperating arm members mounted on said base portion and extending upwardly from the ski member with a first and second opposing grip members mounted on the first and second members of arm, respectively.

Another record registered as patent WO 2015079328 A1 of Pappenheim, Monsegny refers to an assembly for a walking device that includes a star support device and three wheels on its front axle and two wheels on its rear piano and where the star support carries pairs of wheels at each end. This invention seeks the permanent contact of the wheels with the floor of some staircases following the contour of the obstacle to face in the course, but it is not useful before sandy surfaces, snow or the like; and it differs greatly from the invention proposed in this application.

Another antecedent, the utility model requested in Spain with application number: ES 1 051 650 U by Clement Jurado, refers to a device to adapt to a baby car that rolls on sandy surfaces, beaches or the like that includes a mounting of pieces with an external surface close to a cylinder, regardless of whether it is faceted or not, or equipped with the outer area of slight protrusions located in the inner area of the two front wheels and in the inner area the two rear wheels or only in one of the wheel trains, this model differs at a glance from the model that will be described in this application, since the latter also serves to overcome obstacles such as stairs and also the connection between the wheels occurs on the sides, some front with their corresponding backs and they do it through other very different pieces. It is also necessary to place the device on both trains of the car.

Other designs that offer the solutions of running or sliding to the same problem, require modification of the front axle of taxiing, or the rear axle; or even both, or the placement of 3 or 4 devices, one per wheel, which occupy a large volume and are not so easy to store when not in use. The innovation proposed here is that there is no need to modify the structure of the baby carriage or its previous or subsequent train as in examples already cited, if not using an auxiliary device of easy placement and removal, and that manages to adapt to the system of wheels of most of the models already existing in the market, and once placed allows not only up and down stairs but also easily slide on sand, snow or surfaces similar to those mentioned and that when collected take up relatively little space .

EXPLANATION OF THE INVENTION

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes an auxiliary device composed of a track type band that will be positioned below the wheels of the stroller, an insertion system and a clamping system between said band and the baby carriage The caterpillar band constitutes a flexible belt with a set of rigid links attached to each other. The links are metal or plastic plates with holes to allow the connection of each other or the screwing of shoes. They are connected in series and in parallel and help the car to distribute the weight on a larger surface than it would have had using only the wheels, and this makes it possible to move through a larger number of surfaces (including sand and snow) without sinking due at its own weight and allows you to go up or down stairs by sliding the car, resting on that band.

This band fulfills the following functions:

- To serve as support for the wheels of the car that rest on it in a way that supports the weight of the car and is interposed between the wheels and the ground.

- Allow the sliding of the stroller from one place to another without the need for the wheels to turn, thanks to the push or pull of the person in charge of the stroller.

The track type band is composed of sections of links, these are elements of a resistant material such as plastic and its derivatives, metal, wood or even rubber and properly fitted or related to each other. It is possible to add or remove one or more links according to the need to obtain a longer or shorter band respectively, depending on the distance between the front and rear wheels of the stroller; so that the band (a band on each side of the stroller) is tense and firm once attached at each of its two ends to the area of the corresponding stroller.

To place the auxiliary device object of this request, the person in charge of the stroller will deploy or unwind the track type band that can be collected conveniently by winding on itself. Having the caterpillar band completely stretched on the ground and with its smoother or regular surface in contact with the ground surface, we raise one side of the baby stroller and locate the

Track type band below the wheels, so that by letting the wheels rest back to the ground, they now rest on the inner surface of the track type band (surface facing up) then each end of the band to the rocket, for this the terminal part of each side of the band must embrace or be in close contact with the outer face (from a longitudinal point of view) of the wheels, so that the front end of the band covers or Embrace the front part of the front wheel (s) and also the other end of the band, you should hug or cover most of the rear wheel / s.

In a preferred embodiment, the internal surface of the track-type band and at the level of the area that will be in close contact with the wheel, will present small sheets of rubber or silicone, which act as a means of containment to avoid e! sliding of the track type band towards the wheel and from one band to the other (when they overlap each other for example when both bands reach the same wheel, as is the case with three-wheel strollers). Said sheets of silicone or rubber can be placed by the user of the device in the internal area of the links that will be in contact with the wheel, since the size of this can vary according to the model of the stroller, for this the rubber sheets or silicone present on one of its faces a surface with glue as a sticker

Then the end of the band is attached to the point of the stroller closest to the wheels, normally it will be the arm that takes the wheel at its end, although according to the model of the stroller there may be another part of greater convenience as the point of attachment where The tie down strap must be tied one point above the center axis of the wheel.

In a preferred embodiment, the track type band has at the last link of each end of the band (links that can only be used as end ends of the track type band), three grooves centered on the edges; right, left and at the most distal edge of the band and whose shape is rectangular with a semicircle centered on one of its longer sides and whose perforation covers the entire thickness or thickness of the terminal link (these slots are part of the insertion means main), also has a small circular hole (these holes are part of the auxiliary insertion means) on each side of the three slots to pass or cross a cord of fabric or plastic that can be used to add more

stability and firmness to the functional placement of the device, since it will end up tied to the arm of the stroller that supports the wheel or to some other nearby piece that provides us with a stable hold of the assembly. The use of the cord will be optional (it includes an auxiliary fastening means), although it is advisable to keep the system fixed for several days by moving the car on the same surface, such as a trip to the snow or the beach in which it is not need to fold the stroller (the device must be removed whenever the stroller is to be folded). In a preferred embodiment, the rectangular grooves already mentioned, on the three free edges of both terminal links, act as a buckle, allowing the passage of tapes (usually of cloth) through them to approximate and hold the caterpillar band to the body of the baby carriage (these belts comprise a main fastening means). Both the grooves and the holes on each side of it extend from one side of the band to the other, crossing the entire thickness of the band, allowing light to pass through.

In a preferred embodiment, the tapes (main fastening means) that pass through the aforementioned rectangular grooves (main insertion means), have the velcro system or magic closure so that one end of the tape is closed with the other and remains Firmly tied the device.

The links of the body of the band have small grooves at the level of the lateral ends with a central buckle-like partition (which include auxiliary fastening means) to facilitate the passage of some fastening tape or cord if more tension is necessary or firmness in the track type band; getting an extra support.

In another preferred embodiment, the tapes that cross the aforementioned rectangular grooves, have at their ends discs, made of a metal or plastic, where a circular lip in one of the discs enters into a groove in the opposite part of the other disc , as a male and female, getting a pressure closure and the device being firmly attached.

In another preferred embodiment, the ribbons that cross the aforementioned rectangular grooves, have at their ends a plastic snap system, as a side release buckle, regardless of whether the male or female part is attached to the end of the type band caterpillar, while the other part where this fuck fits the

part of the corresponding baby stroller structure.

In another preferred embodiment, having the terminal links with the grooves already mentioned in the caterpillar band, the fastening to the stroller is made thanks to a carabiner hook element that is fastened through a velcro closure fabric strap, or if not by a pressure closure to the arm of the stroller that supports the wheel or some other nearby piece that provides us with a stable hold of the set.

In another preferred embodiment, the device will have different terminal links to the rest of the links in the body and different from the other terminal links already mentioned, although they can also only be used as links in the end ends of the band, these will have different grooves than the other previously described; three grooves in the outer face, which is smoother and more regular of the caterpillar band, and another groove in each of the free edges or edges of the terminal link, perpendicular and centered in relation to the grooves of the upper surface, ( all these grooves comprise main insertion means) forming a female-like system, whose tarnaho and shape vary according to the tarnaho and shape of the joint element as a male hitch. This "male" part or element will be tied or fastened by a fabric strap that has a velcro closure or a snap closure and that will attach it to the arm of the stroller that supports the wheel or some other nearby piece that provides us with a stable support This link will also present the small circular hole on each side of the female grooves, for the passage of the auxiliary cords.

To correctly attach the track type band to the stroller; the belt should be passed through one of the three slots that has the terminal link of the caterpillar band (as threading it) and we will go with the two ends of the belt to surround the arm of the stroller to finally join them together thanks to the magic closure of the tape or by the snap closure as buttons, depending on the type of fastening tape being used.

The track type band assembly and the means of attachment to the stroller should be as firm and tense as possible, closely adjusting to the outer contour of the front and rear wheels on the right side (with a device) and on the left side (with a second device) so that the portion of track type band that remains

between the front and the rear wheel is not loose, if so! it would be necessary to tie the ends of the band to a more distant point and that it obtains a greater tension of the set, or else to remove some link of the caterpillar band since it could be being longer than convenient: this possibility of adjusting the length of the band will allow to adapt to the different sizes of cars and wheels that exist in the market.

With this invention, the user is not required to change his cart, or the wheel system he currently has, since it can be attached or placed in many existing baby cars or strollers, adapting to the wheel system of most the models, thus avoiding laborious modifications and expenses that these would entail. In addition, using the system proposed in this application, the time required to go up or down the stairs carrying the baby car is reduced, the need to require the use of an elevator is avoided unless the user prefers, and also It becomes optional to request help, since a single person can easily overcome the obstacle represented by the stairs, giving more independence, a very noticeable advantage since many times there is no availability of elevators or people attending or helping to raise / lower the stroller Drink up some stairs. It is also important to mention that using this device is much more likely to be safe both the child who travels in the stroller and the person who carries it, because jumps or blows that a car between steps and steps are avoided, or when falling into a hole, since when using the device; The stroller will be sliding more smoothly and controlled. In addition and as already mentioned, it is easier to move the baby carriage on sandy, snowy or similar surfaces.

In those cases in which the baby carriage only has three wheel axles, usually one front and two rear, the device mentioned in this application could also be used, requiring in any case two caterpillar bands, one that goes from the rear wheel right to the front wheel / s / s central / s, and another track type band that is placed from the left rear wheel to the front wheel / s / s, so that with the first track type band Proceed as mentioned above and the following track type band on the remaining side will be placed on the rear wheel normally and in the central front it will be placed below and hugging the already placed track type band,
