This invention relates generally to a hood and a cover and, more particularly, to a hood and a cover for a child carrier or transport vehicle, such as a carrycot, pram, baby-buggy, stroller or Moses basket, configured to provide protection against pollutants and/or thermal comfort, in use, to a child being transported, or otherwise located, therein.
It is common to provide a removable cover for devices such as prams, strollers, carrycots, baby-buggies and Moses baskets, to protect an infant or young child being transported (or even just resting) therein from the elements when outdoors. Thus, removable rain covers are usually provided for strollers, to protect a child in wet weather, and removable parasols or other sun shading devices may also be provided, to shield a child from the sun's rays in hot weather.
It is less common, but nevertheless also known, to provide a cover for a stroller or other child transport vehicle, that is configured and intended to protect an infant or child seated therein against air pollution. For example, U.S. Pat. No. 6,068,322 describes a transparent canopy that, in use, covers an infant seated within a baby-buggy to define a compartment around them, and comprises a battery-powered fan unit including a carbon-impregnated filter for blowing filtered ambient air into the compartment. The filter unit is located and configured to blow the filtered (ambient) air into the top of the compartment from the rear (between the buggy seat back and the canopy). The canopy extends and hangs down over the seated child and the bottom of the canopy is open. Operation of the filter unit creates positive pressure within the compartment so that filtered air flows downwardly therethrough (relative to the seated child's face and body), from the filter unit to the open end of the compartment. A mesh insert in the canopy at the ‘front’ of the compartment provides ventilation and is intended to prevent heat build up.
However, the above-described cover is intended to protect a seated (i.e. inclined) child and is not configured for use with (and the principle would be difficult to apply to) a carrycot, pram or moses basket, wherein the infant is lying substantially flat on their back, as it would be difficult to provide the required open end of the compartment without additional support features. Even if this were considered possible, the arrangement would not work as intended, because it also relies on a mechanism known as “flotation”, more widely known as “hot air rises”. Thus, as the cooler air from the fan unit is directed downwardly through the compartment, the warmer air toward the bottom will rise up through the canopy and (in theory, at least) be expelled through the mesh insert. Furthermore, even if a similar arrangement were to be realisable for a carrycot, say, there is no directional control of the air flow over the infant as the positive air pressure and air flow will tend to be equal throughout the compartment, which would result in air from the fan unit blowing directly onto the prone infant's face and around their neck and shoulders, which is clearly undesirable, especially in respect of very young babies. More generally, the transparent canopy and open end do not provide complete protection for the child, and are particularly inadequate in protecting the child from the sun or, indeed, very hot temperatures as the configuration of the arrangement depends, additionally, on movement of the underlying device to regulate temperature and prevent heat build-up, not to mention the fact that the cover is really only intended for short term periods of use to transport a child outdoors between one location and another, and would not be suitable for longer term, stationary periods, to protect a child as it slept, for example.
It is an object of the present invention to address at least some of these issues.
In accordance with an aspect of the invention, there is provided a hood for a child carrier comprising:
In accordance with another aspect of the present invention, there is provided a removable cover assembly for an infant carrier or child transport device comprising a receptacle or seat for receiving an infant or child, in use, the cover assembly comprising a cover formed of a pair of side walls, a top wall and a front wall, said side, top and front walls defining a canopy configured to fit over said receptacle or seat to form a compartment enclosing an infant or child therein, in use; wherein said canopy is formed of a flexible material and the cover assembly further comprises:
said first and second fan units being mounted and sealed within a respective opening in a different respective one of the side walls, top wall and front wall of said cover such that, in use, an air flow path is defined through a volume of said compartment between said first and second fan units.
Unless specified otherwise, the features described below are applicable to both the hood and the removable cover assembly.
Optionally said fan unit may also further comprise a filter member. Optionally said first fan unit may comprise a recess for receiving a replaceable filter member in an air flow path of said ambient external air. This replaceable filter member may advantageously be formed of an active carbon filter. In addition to these aspects, at least one of the first and second fan units may additionally comprise a power supply, and each said fan may be electrically coupled to the, or each respective, power supply. The power supply, or each power supply, may also comprise a switch mechanism for selective operation thereof. The power supply, or each power supply, may also be formed of at least one battery.

The hood can be pivotably mounted to the receptacle and can be moveable relative to the receptacle between an expanded state and a collapsed state.
Where the hood comprises a front wall, the front wall can be extendable from the hood towards an opposing end of the receptacle. The front wall of the hood can comprise fastening means for fastening the front wall to the opposing end of the receptacle, e.g. an elasticated edge, or fastening means such as zip, button or hook-and-loop fastening means. When the hood is in the expanded state and the front wall is extended from the hood to the opposing side of the receptacle, the hood and front wall can completely enclose the receptacle from above such that the cavity is completely enclosed.
According to another aspect of the invention, there is provided a child transport device (e.g. pram, pushchair, stroller) comprising:
These and other aspects of the present invention will be apparent from the following detailed description.
An embodiment of the present invention will now be described, by way of example only, and with reference to the accompanying drawings, in which:
Referring to
The side, rear, top and front walls 16a, 16b, 18, 20, 22 may comprise separate panels of material, joined together at their respective side edges, or one or more (or all) of the panels may, in fact, be formed integrally with each other, and the present invention is not necessarily intended to be limited in this regard. The opaque material forming the walls 16a, 16b, 18, 20, 22 may comprise a fabric of around 270-300 gsm and be resiliently flexible in that it has a relatively small amount of elasticity or stretch incorporated therein. For example, a polyester or polyester mix including a small percentage (e.g. less than 10%) of elastic polyurethane fibre or fabric, or indeed a Gore-Tex® stretch material (or similar) may be used. Other suitable materials will be apparent to a person skilled in the art.
Referring to
Referring back to
The cover assembly further comprises first and second fan units 26, 28. Referring additionally to
The filter member 46 may, for example, comprise a replaceable active carbon filter of a known type, which in this case is in the form of a corrugated cartridge of activated carbon filter mesh, although other replaceable filter members will be known to a person skilled in the art, and the present invention is not necessarily intended to be limited in this regard. Nevertheless, active carbon filter members are known to trap all particles with dimensions larger than 3-5 microns and are an excellent barrier against industrial dust, exhaust gas and smaller microorganisms, a significant cause of lung disease, and are therefore considered to be particularly useful in at least some exemplary embodiments of the present invention.
When the fan unit 26 is fully assembled, the fan 40 is electrically connected to the power supply defined by the batteries 36 within the power supply recess 32. The housing 30 defines, around its periphery adjacent its front face, a frame portion 48 (not shown in
The second fan unit 28 may, in some exemplary embodiments of the present invention, be almost identical to the first fan unit 26 described above and include the power supply as defined by the power supply recess and the batteries 36, but not the filter recess 44 and filter member 46 (or, indeed, the aperture 38 in the rear wall of the fan recess 36). However, in some exemplary embodiments, the power supply portion of the second fan unit 28 may also be eliminated, as in the exemplary embodiment illustrated herein, such that the second fan unit 28 comprises only the fan recess 36, fan 40 and fan grill 42, aperture 38 substantially as described above in relation to the first fan unit 26. Once again, the housing 30′ of the second filter unit 28 defines, around its periphery adjacent its front face, a frame portion 48′. The housing 30′ is mounted within an opening in the opposite side wall 16b of the cover 14 to that in which the first filter unit 26 is mounted, such that the frame portion 48′ thereof lies against the outer surface of the cover and the rest of the housing 30′ is on the inside of the cover 14. Thus, and as shown in
As the second fan unit 28 does not have its own power supply in the exemplary embodiment illustrated, there is a need to provide an electrical connection from the power supply of the first fan unit 26 to the second fan unit 28. This may be achieved, for example, by running a flexible electrical connector (not shown) in the peripheral loop around the open end of the cover provided for the fastening cord, for example, from the power supply of the first fan unit 26 to the second fan unit 28, although other methods of achieving this may be apparent to a person skilled in the art and the present invention is not necessarily intended to be limited in this regard.
The fan 40 of the first fan unit 26 is configured, in use, to draw ambient air from the outside of the cover 14, through the filter member 46, into the compartment defined between the receptacle of the carrycot and the cover assembly 10. The fan 40 of the second filter unit 28 is configured, in use, to draw air from within the above-mentioned compartment and into the environment surrounding the assembly. Thus, and referring to
As a result, the ambient air can be filtered, and the temperature within the compartment actively controlled, without disturbing the infant or causing it any distress. As shown in
In some exemplary embodiments, a temperature sensor (not shown) may be provided within the compartment formed, in use, between the cover 14 and the carrycot receptacle to obtain data representative of the temperature therein. Such temperature data may, for example, be used to provide a temperature display, on (or visible from) the outside of the cover 14. In other exemplary embodiments, the temperature data may, alternatively or in addition, be used to control the speed of the fans 40 in the fan units 26, 28, thereby to increase their speed of rotation if the temperature is above a predetermined threshold and reduce their speed of rotation if the temperature in the compartment falls below a predetermined threshold. An electronic control unit to achieve this functionality may, for example, be provided in the first fan unit housing 30. The cover 14 may include a fastening member at a convenient location on its inner surface, for receiving and removably holding accessories such as a temperature sensor, toy, mobile, etc.
In yet another exemplary embodiment, an air quality sensor (not shown), may be provided within the carrycot receptacle to obtain data representative of the amount of pollution or, harmful air particulates and substances (such as smog) in the surrounding area to the carrycot. Such air quality data may, for example, be used to provide a display indicative of the pollution levels. This display may be shown on a screen or display unit fitted to the outside of the carrycot cover, such that it can be seen by those looking at the carrycot.
In other exemplary embodiments, said temperature and/or air quality sensor may be communicably coupled with a program or application on a user mobile device.
In addition to providing the fan units as part of a removable cover assembly, the fan units can also be integrated into a hood for mounting to a child carrier.
The hood is symmetrical on both sides and therefore in
When the front arch member 110a is in its lowered position, the flexible material is folded and the hood 110 is in a collapsed state. When the front arch member 110a is moved to its raised position, the flexible material unfolds and the hood 110 is in an extended state in which the side walls 116a, 116b. rear wall 118, and top wall 120 form an open compartment at one end of the receptacle 112 over the cavity. The front arch member 110a may be releasably locked in the raised position relative to the receptacle 112, e.g. by a releasable snap fit connection, so that the hood 110 can stay extended until the user decides to collapse it.
The hood 110 further comprises a first fan unit 126 and a second fan unit 128. The first fan unit 126 is mounted in one side wall 116a of the hood 110 and the second fan unit 128 is mounted in the other side wall 116b of the hood 110 so that the fan units 126, 128 generally oppose each other. Similar to the cover assembly 10, the first fan unit 126 comprises a fan configured, in use, to draw ambient external air into the compartment and the second fan unit 128 comprises a fan configured, in use, to draw air from within the compartment to the environment outside the compartment.
Thus, a controlled air flow path is defined between the two fan units 126, 128 over the top of the receptacle 112 where the child's head would be located, in use. The first fan unit 126 and second fan unit 128 do not necessarily have to be mounted on opposing side walls of the hood 110, and each could be mounted on a different side wall, top wall or rear wall, as long as an air flow path is defined through a volume of the compartment between the first and second fan units.
The first and second fan units 126, 128 are powered by an external power supply 134 that is mounted on or within the rear wall 118 of the hood 110. Alternatively, the power supply could be mounted on or within the base 112a or side wall 112b of the receptacle 112, or mounted within the housing of one or both of the fan units 126, 128. The power supply may receive traditional batteries, or may be a rechargeable power supply. Electrical wires (not shown) can be sewn into the walls of the hood 110 and/or the receptacle 112 between the power supply and the first and second fan units 126, 128 to provide power to the fan units. The electrical wires may be covered in foam to improve the feel of the hood 110. It will be recognised that due to the presence of the first and second fan units in the walls of the hood 110, the hood 110 may not be completely flat in its collapsed state and may only collapse down to a partially collapsed state.
The first and second fan units 26, 28 described above in relation to the cover assembly 10 are substantially identical to the first and second units 126, 128 of the hood 110 and the description of the first and second fan units 26, 28 is equally applicable to the first and second fan units 126, 128. For example, the details of the housing, the way in which the fan units are mounted in the walls, the filter member etc. are all equally applicable to the first and second fan units 126, 128 of the hood 110. A detailed description of the first and second fan units 126, 128 will therefore not be repeated here.
The hood 110 can further comprise a front wall 122. The front wall 122 is configured to extend forwardly from the hood 110 towards an opposing end of the receptacle 112 (i.e. the end of the receptacle opposing the end at which the hood is provided). Together, the side walls 116a, 116b, rear wall 118, top wall 120 and front wall 122 of the hood 110 can completely enclose the receptacle 112 from above so that the cavity of the receptacle 112 is completely enclosed. The front wall 122 can be permanently or removably attached at one end to one of the walls of the hood 110 or the front arch member 110a. The other end of the front wall can be removably attached to the opposing end of the receptacle by fastening means such as zip, button or hook-and-loop fasteners, or by providing the front wall 122 with an elasticated edge that can be extended over an upper rim on the receptacle. Alternatively, the front wall 122 does not need to extend all the way to the opposing end of the receptacle and can just extend partially toward the opposing end of the receptacle. In this case, the front wall 122 can be provided with a flexible wireframe for support.
The front wall 122 is made from a flexible material and can be stored within the hood 110 when not in use. For example, the inner surface of the hood 110 could have a pocket (not shown) in which the front wall 122 can be stored in a folded state. One end of the front wall 122 can be permanently attached to the pocket or one of the walls of the hood 110. The front wall 122 can be made from, or at least comprise a portion made from, a mesh or net material to provide breathability and protection from bodies such as insects and the glare of the sun. Alternatively, the front wall 122 can be made from a close-knit material.
It will be recognised that even if the front wall 122 is not extended or provided, the first and second fan units 126, 128 mounted in the in hood 110 will still provide a similar effect as the removable cover 10 to provide a clean, temperature-controlled environment for the child in the child carrier.
The temperature sensor and/or air quality sensor as described above in relation to the cover assembly 10 can also be provided in the hood 110 or receptacle 112 for the same purpose.
The child carrier can comprise attachment means that allow the receptacle 112 to be attached to a frame 160 with wheels 162 so that the child carrier can be transported without the user needing to carry the child carrier. For example, the receptacle and the frame can comprise corresponding releasable snap fit connectors 164a, 164b that allow the child carrier to be attached and detached from the frame 160. The wheels 162 may be permanently attached to the frame or may be releasably coupled to the frame for convenient transport and storage.
It will be apparent to a person skilled in the art from the foregoing description, that modifications and variations can be made to the described embodiments without departing from the scope of the invention as defined by the appended claims.
