478,195 7/1892 Lewis et al 2/227 8 Claims, 1 Drawing Figure This invention relates to trousers. In particular, the invention is directed to work trousers made of substantially airtight material.
The problem of ventilation presents itself especially with work trousers wherein, by virtue of perspiration due to physical exertion, a permanent damp state exists. The problem of ventilation is aggravated in situations where work trousers are made of substantially airtight material in that ventilation is, practially, not possible at all. Particularly, this invention is directed to providing ventilation in the very region where the greatest amount of perspiration is secreted, viz., between thelegs.
The invention is directed to providing effective ventilation without hampering or impairing the physical activity of the wearer of the work trousers and yet maintaining the protective advantage of the material employed in the work trousers. In the past, trousers have been provided with vent openings. However, these openings have been disposed either immediately below the waistline and parallel thereto or else at the front of the trousers. These slits or vent openings permitted only incomplete ventilation, for the openings were not disposed in the very region where the greatest amount of perspiration is secreted, viz., between the legs.
Use of pierced eyelets to provide openings in the leg pieces of trousers had the disadvantage ofimpairing the walking and movement capability of the wearer. Moreover, such eyelets provided a potential risk of damaging trousers by the rubbing action of such eyelets against the trouser material. Obviously, the risk of damaging the trousers increased when eyelets were placed on the inner leg piece of the trousers due to such rubbing action.
Slits in the seats of the trousers had the disadvantages of opening when the wearer of the trousers sat down. Thus, even if the trousers were made of waterand/or chemical-repellent material, the trousers lost their protective effect.
The instant invention is directed to providing effective ventilation without the aforementioned disadvantages. The instant invention provides effective ventilation and yet does not interfere with mobility or de crease agility, and yet provides complete protection in those instances which would require waterand/or chemical-repellent work trousers.
The instant invention is directed to a gusset to be inse rted in the inner leg piece of trousers, or in crotch section of trousers, to provide ventilation. The gusset provides ventilation by virtue of construction of the gusset which has effectively two vent channels. The invention is generally directed to a pair of trousers, having an opening in the inner section of each leg piece of said trousers, and a gusset for the opening in the inner leg piece section which conforms to the shape of the opening and is attached thereto, which gusset comprises three pieces of material, two of said pieces of material overlapping with the third piece of material to form vent channels. The desirable features of this invention will become apparent on consideration of the drawings.
The drawing shows an embodiment of the invention in a partial sectional view.
In the drawings, the trousers 1, may be made of substantially air-tight material. The trousers 1 have a gusset 2 composed of two halves 3 and 4, each of which extend along one of the leg pieces 6 or 7. The two gusset halves 3 and 4 may stretch from the seat piece along the leg pieces 6 and 7 and may taper off towards the bottom. The gusset halves 3 and 4 comprise an outer insertion 8 and an inner insertion 9. The outer insertion 8 and the inner insertion 9 overlap each other. The overlapping of outer insertion 8 and inner insertion 9 provide the vent panels which provide ventilation, as will become apparent below.
Each inner insertion 9 extends from one of the lower ends of gusset 2 to the seat piece 5, whereby the upper edges 10 are positioned so as to form an opening between them and the inside of the trousers.
On its upper ends, each insertion 9 is covered by the corresponding outer insertion 8. The outer insertion 8 is attached to the remaining trouser piece 13 along its two side edges 12, so that edge 14 of outer insertion 8 lies lossely against the corresponding inner insertion.
At least one edge 14 of outer insertions 8 should lie loosely against the corresponding inner insertions 9, so that the gusset has at least one vent channel. Thus it is apparent that the gusset of this invetion may be formed of two pieces of material which overlap to form one vent channel. However, preferably for-maximum ventilation, both edges 14 of outer insertions 8 lie loosely against the inner insertions 9 to form two vent channels.
The method of attaching outer insertion 8 to the trouser piece 13 depends on the materials employed to form the trousers and the material forming the gusset.
Since edge 14 lies loosely against the'corresponding inner insertion, a vent passage 15 remains open extending from the trousers outer side to the trousers inner side. The vent passage results from the described placement of the upper edges 10 of the inner insertion 9.
As indicated by the description of the drawings above, the passage 15 and the opening 10 form a vent channel, allowing the passage of air into the trousers. The passage 15 and the opening 10 allow for ventilation and evaporation of moisture, on the one hand. On the other hand, the gusset formed by the arrangement of the two gusset halves, 3 and 4, assist in retaining the protective properties, particularly desirable in waterand chemical-repellent trousers. Moreover, the invention provides for ventilation in trousers, particularly work trousers, without hindering the movements, mobility and agility of the wearer.
While the invention will be described below in connection with the preferred embodiment, it will be understood that it is not intended to limit the invention to that embodiment. On the contrary, it is intended to cover all alternatives, modifications, and equivalents as may be included within the spirit and the scope of the invention as defined by the appended claims.
Broadly stated, the invention is a gusset for trousers which provides effective ventilation, particularly between the legs. This invention finds particular utility in trousers which are made of substantially air-tight material. Such air-tight material may be selected from natural or synthetic rubbers, plastics and fabrics of natural or synthetic fibers or mixtures thereof which have-been rendered wateror chemical-repellent by virtue of coating or coating procedures. The gusset which is arbitrarily comprised of two halves, 3 and 4, may be formed of the same material as the trousers or of different material. Depending on the nature of the two types of material employed for the trousers and the gusset in- 4 sert, attachment of the gusset to the trousers may be effected by sewing, by adhesives or by heat treatment. As described in the drawings, the two halves, 3 and 4, of the gusset comprise outer insertion 8 and inner insertion 9. Preferably the outer insertions 8 are two independent pieces which are attached to each other. When outer insertions 8 are independent pieces, they can be shaped to conform to the outline of the body in that area. However, it is within the scope of this invention that the two outer insertions 8 of the gusset halves, 3 and 4, consist of one piece of material. Preferably, irrespective of whether outer insertions 8 of the twogusset halves, 3 and 4, are two independent pieces or one piece, the two gusset halves, 3 and 4, stretch from the seat piece along one of the leg pieces 6 or 7 and taper off towards the bottom, as shown in the drawing.
It is apparent that there has been provided, in accordance with the invention, a modification for work trousers that fully satisfies the objects, aims, and advantages set forth above. While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations as fall within the spirit and broad scope of the appended claims.
