Description

SPECIFICATION Improvements in or relating to pumps The present invention concerns improvements in or relating to pumps. More particularly, the present invention is concerned with pump means locatable in or forming part of footwear or clothing.
There has always been a problem when wearing rubber or plastic boots and shoes, that as there is little or no air circulation around the foot, a build up of perspiration causes very unpleasant and uncomfortable conditions and can lead to medical problems of many kinds. A similar situation exists with plastic gloves such as those used in germ warfare-- medical and other contamination cabinets, where the user encounters considerable perspiration build up.
It is an object of the present invention to provide a pump means which will at least minimise the problems referred to above.
It is a further object of the present invention to provide a pump means which will permit air to circulate in an enclosed area of footwear of clothing.
In the case of a footwear article, it is an object of the present invention to generate a circulation of air around the foot in such a manner as to continuously change the air, by taking in fresh air outside the footwear article which is passed clean and fresh to the foot and then exhausted up the leg of the footwear article carring with the air excess moisture generated by the foot.
According to the present invention there is provided pump means locatable in or forming part of a footwear or clothing article comprising wall means defining an enclosed space, and inlet means leading to said space for permitting entry of air into said space and including a non-return valve, outlet means leading from said space for permitting expulsion of airfrom said space and including a non-return valve, and resilient means for urging at least portions of the wall means apart so as to maintain said space, said resilient means being provided by the wall means being resilient in nature or separate resilient means being provided in said space, wherein said inlet means extends away from the wall means and is of such a length of such dimension asto enable, in use, air to be drawn into said space either from the exterior of the article or from a region spaced apart from the outlet means.
In one embodiment of the present invention, the wall means comprises a sealed envelope of an airproof material, e.g. plastics material and the resilient means comprises a pad of resilient material, such as open cell foam rubber or plastics material, located within said envelope.
Said inlet means may be formed of similar airproof material and the outlet means may be produced by provision of openings in the sealed envelope, both the inlet and outlet means having respective non-return valves associated therewith.
It is also possible to incorporate such pump means within an insole or insock which can be slipped into the foot part of a pair of boots with the inlet means extending to the outside. The insole or insock may be made of such material as will allow easy air circulation under the sock such as plastics material meshes, certian felts and open weave fabrics, and combinations thereof. It is also possible for medical use to fit a medication dispensing device in the inlet means to give continual medication.
In a further embodiment of the invention, the pump means is either moulded in the sole of the shoe at the manufacturing stage or is moulded into the insole or insock. In such case, a plastic injection moulding unit would be utilised which would generally be manufactured as two halves, and the two halves welded together in the form of a sandwich. The enclosed space would be formed in the moulding process together with the valves, distribution channels and outlet means. In such case, the sole of the shoe or the insole or insock would be formed of resilient material.
It can thus be seen that the pump means of the present invention can be used for numerous applications in footwear and clothing. In the ensuing description, and purely by way of illustration, reference will be made to the pump means of the invention being located in or forming part of a footwear article.
The present invention will be further illustrated, by way of exampie, with reference to the accompanying drawings, in which: Fig. 1 is a side view of a boot having a pump means in accordance with the presnt invention located therein; Fig. 2 is a perspective view, partly in section, of a pump means utilised in the embodiment of Fig. 1; Fig. 3 is a perspective view, partly in section, of a pump means in accordance with the invention located in an insole or insock; Fig. 4 is a side view, partly in section, of an insole or insock produced by injection moulding techniques, said pump means forming part of said insole or insock; and Fig. 5 is a side view, partly in section, of the sole of a boot or shoe, again produced by injection moulding techniques, said pump means forming part of said sole.
As illustrated in Fig. 1, a pump means in accordance with the present invention, generally referenced 10, is located in a boot 11.The pump means 10 is located on the insole 12 of boot 11. The pump means 10 has an inlet tube 13 which extends up to the side of the boot with the open end 14 of the inlet tube 13 being open to the atmosphere.
As illustrated in Fig. 2, the pump means 10 consists of a pair of air-proof members sealed together to form an envelope 15, said envelope containing a pad 16 of resilient material, such as open cell foam rubber or plastics material. The inlet tube 13 is corrected to the sealed envelope 15 by means of a non-return inlet valve. The envelope 15 has also one or more non-return outlet valves. The inlet and outlet valves will be described in more detail in the embodiment disclosed in Fig. 5.
As illustrated in Fig. 2, an elongate a resilient spacer member 17 is located in the inlet tube 13, so as to keep the walls thereof apart and permit air to enter the inlet tube 13 from the atmosphere as indicated by arrows A.
The sealed envelope 15 is produced by joining two sheets of air-proof plastics material together at their edges. The resilient member 16 is located in said envelope 15 and held in position by means of a weld joint 18. Such joint is interrupted at various positions, e.g. 19, 19' . . ., at which positions nonreturn outlet valves are located. Air is allowed to be pumped out of the pump means 10 as indicated by arrows B by the provision of holes, 20, 20'..., provided in the region where the edges of the plastics material sheets forming the envelope 15 are joined.
The embodiment illustrated in Fig. 3 shows the pump means 10 being located in an insock or insole 21.The inlet tube 13 extends up the side of the boot with the open end thereof open to the atmosphere.
The sealed envelope 13 containing resilient member 16 is located within the insole or insock 21. Such insole or insock 21 is made of such material which will permit easy air circulation under the foot, such as in the form of plastic meshes, felts and open weave fabrics or a combination thereof.
Having regard to the embodiments illustrated in Figs. 1, 2 and 3 when the pump means is located in a boot, as the wearer walks his or her body weight is transferred through the foot onto the pump means.
Air trapped in the envelope 15 is forced out by pressure through the outlet valves, 19, 19'. When the foot is lifted to take another step, the resilient member or pad 16 returns to its non-compressed state and draws air into the envelope 15 via the inlet valve 4, as indicated by arrows C. Thus, with each step a small volume of air passes through the foot pad envelope 15 and is discharged as fresh dry air round the foot.
It can also be seen that as the air passes down the inlet tube 13 in close proximity to the leg, the air will be slightly warmed. Alternatively, in extreme cases of cold the air could be warmed by external heating means. The warmed air will readily absorb moisture for transfer out of the boot to help keep the feet in a dry warm condition. Thus, the pump of the invention will help to solve the problems of condensation and assist with the problem of cold feet generally due to poor blood circulation.
The pump means can be of any desired suitable shape and, in certain instances, may be so shaped so as to ventilate certain areas of the foot, such as between the toes, to dry out the perspiration which tends to form the perfect breeding ground for bacteria leading to many forms of skin problems.
Afurther applicatioan of the pump means as illustrated in Figs. 1, 2 and 3 of the invention is for use in connection with the hose-like article of clothing described and claimed in my co-opening U.K. Application No. 8517367. The use of such pump means enables the foot to breath when such articles of clothing as disclosed in my co-pending application are used with a completely airtight outer boot or shoe which prevents escape of moisture.
The pump means will therefore be used inside the boot or shoe but outside the articles forming the subject matter of my copending application referred to above.
Whilst the embodiment of Figs. 1, 2 and 3 have disclosed the pump means of the present invention being locatable in footwear, the embodiments hereinafter described in relation to Figs. 4 and 5 indicate an arrangement wherein the pump means forms part of such footwear.
In the embodiments disclosed in Figs. 4 and 5, the insole or insock of Fig. 4, and the sole of the shoe or boot of Fig. 5 are formed by plastic injection moulding techniques.
As illustrated in Fig. 4, an insole or insock, generally referenced 40, comprises wall means 41 which between them define an enclosed space 42. In the regin of the portion of the insole 43 a plurality of outlets, 44,.... ., are provided, and air is passed from the space 42 to such outlets by means of distribution channel 45. Air is drawn into the space 42 from the inlet tube 13. Such inlet tube is connected to the enclosed space 42 by means of a non-return valve and air passes out from the enclosed space to the distribution channel 45 by means of non-return valve 46. The insole or insock is formed of resilient material.
As illustrated in Fig. 5, the sole, generally referenced 50, of a shoe is formed of resilient material and produced by plastic injection moulding techniques.
In this embodiment, the pump means comprises a plurality of resilient cavities 51, 51', 51"... ,formed in portions 50A of the sole 50 such cavities being connected to the inlet tube 13 by means of distribution channel 52. The inlet tube 13, as in the other embodiments, is provided with a spacer member 17 to keep the inlet tube open. The inlet tube is connected to the distribution channel 52 by means of a non-return valve 53. In turn, air passes through the distribution channel 52 into the cavities, 51,51', 51" by means of inlet valves 54,54', 54". Air passes out of the cavities 51,51 51" by means of outlet valves 55,55', 55".
In the case of the pump design to be built into the shoe at the manufacturing stage, as illustrated in Fig. 5, the operation is similar to that of Fig. 4 in that air is drawn down the inlet tube 13 into the distribution channel network 52 within the sole 50.
The pump cavities,51,51 51", which can be any number required, are distributed over the whole of the sole area as small individual pumps complete with inlet and outlet valves for receiving air from the distribution channel network. The operation is similar to that disclosed in Fig. 4, in that when a person applies his or her weight onto the sole 50, the resilient nature of the material of the sole permits the sole to be compressed including all the resilient cavities 51,51 51", which forces air out of the outlet valves 55, 55', 55". When the weight is relieved from the sole 50, the resilient cavities, 51, 51 51" restore themselves to their relaxed state and draw fresh air in through the inlet valves 54, 54', 54" readyforthe next compression operation.
It can thus be seen that the pump means irr accordance with the invention, whether same is locatable in or forming part of footwear, enables fresh air to be circulated throughout the foot region of a a user.
As also previously mentioned, the pump means of the present invention may be located into a pair of plastic gloves in the situation where the user encounters considerable perspiration build-up. It is also possible to have the air supply filtered by carbon and other means, and also to have the air supply warmed in certain cases by chemical or other means for use in very cold climates.
It can thus be seen that the pump means in accorance with the present invention provides an effective arrangement to ensure the circulation of fresh air in the region in which the pump means is located.
