Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This U.S. non-provisional patent application claims priority under 35 U.S.C. §119 of Korean Patent Application No. 10-2014-0084553, filed on Jul. 7, 2014, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present invention disclosed herein relates to sports gloves, winter gloves, waterproof gloves, or working safety gloves, and more particularly, to a glove intermediate membrane having moisture permeability and a waterproof function and simultaneously coupled to an outer shell and an inner liner, gloves using the same, and a manufacturing method therefor.

BACKGROUND ART

Winter gloves or waterproof gloves need a waterproof function that prevents the gloves from being wet from winter rain or water generated from inciting snow from being introduced into hands of a user to warm the hands and, at the same time, a moisture permeable function that discharges sweat generated from the user's hands to the outside to give comfortable feeling.
The gloves are manufactured by using mainly a woven fabric or a knitting fabric. Hereinafter, the waterproof function and the moisture permeable function of the related art will be mainly described.
(1) Since the woven fabric does not have a contraction and expansion property, a process of manufacturing gloves requires a complex cutting and sewing process to match a three-dimensional structure of fingers. A membrane made of a synthetic resin represented by Goretex is used as a membrane for giving the waterproof function and the moisture permeable function to the gloves made of the woven fabric. Unlike clothing, the gloves using the membrane include finger portions that are too narrow not to directly seal a sewing line with an adhesion tape or the like.
FIG. 1 illustrates the waterproof function and the moisture permeable function of conventional gloves in which the above-described intermediate membrane is coupled between an outer shell and an inner liner. According to FIG. 1, an intemiediate membrane 20 is spaced apart from and coupled between an outer shell 30 and an inner liner 20. The gloves discharge sweat 3 generated from a skin 1 through the inner liner 10, the intermediate membrane 20, and the outer shell 30. However, when water 2 is introduced through the outer shell 30, although the intermediate membrane 20 blocks the water 2 to prevent the skin 1 from being wet, a heat-retaining function is sharply reduced when the water is filled between the outer shell 30 and the intermediate membrane 20 to generate ice-formation 4.
FIG. 2 illustrates the waterproof function and the moisture permeable function of another conventional glove in which a coating layer is applied to an inner surface of the outer shell. A limitation regarding the waterproof function in FIG. 1 is resolved by applying a coating layer 32 to the inner surface of the outer shell 30. However, although the sweat 3 generated from the skin 1 is discharged through the intermediate membrane 20, the discharging of the sweat 3 to the outside is blocked by the coating layer 12 to generate a limitation in the moisture permeable function. That is, the coating layer 32 generates the limitation that is mutual conflict between the waterproof and moisture permeable functions, and thus it is required to resolve this limitation.
In particular, when the conventional gloves in FIGS. 1 and 2 are used for racing gloves that are used for downhill ski runs, a motorcycle, or the like, which require an accurate grip feeling, a gap is generated between the outer shell 30, the intermediate membrane 20, and the inner liner 10, which acts as one of factors that decrease athletic performance.
(2) Unlike the gloves made of the woven fabric, since the gloves made of the knitting fabric have an excellent contraction and expansion property, the gloves may be manufactured without a cutting or sewing process. Also, when the user wears the gloves, the hands are free to bend and extend due to the contraction and expansion property of the woven fabric. Thus, unlike the knitting fabric, the woven fabric is widely used for safety gloves or working gloves that are mass-produced at low costs or require a working property. However, the gloves have a fatal limitation that is non-waterproof.
Although all or a portion of a surface of the gloves is dipped into a synthetic rubber solution such as latex to improve the waterproof property of the gloves made of the woven fabric, there is still a limitation in which sweat is not discharged.
Meanwhile, special gloves used for an oil drilling work for producing petroleum or a shale gas production work on the sea need to prevent introduction of seawater or oil and simultaneously require the moisture permeable property and the excellent grip feeling. In particular, the special gloves are not waterproofed when rains. The conventional gloves do not meet the requirements.
The conventional gloves disclosed in Korean Patent Laid-Open Application No. 10-2013-0142042 are constituted by the inner liner and outer shell, which are manufactured by sewing, and a polymer film having a waterproof and windproof property and the moisture permeable property. Also, adhesion members for respectively coupling between ends of the finger portions of the inner liner and the intermediate membrane and between ends of finger portions of the intermediate membrane and the outer shell are provided. Here, each of the adhesion members includes a substrate, a hotmelt adhesion layer disposed on a top surface of the substrate, and an adhesion layer and a hotmelt adhesion layer, which are disposed on a bottom surface of the substrate while disposed on the same plane as each other. Each of the adhesion layers has a bottom surface that is disposed on an outer surface of the end of the finger portion of the inner liner and an outer surface of the end of the finger portion of the intermediate membrane.
In the conventional gloves constituted as above-described, the adhesion member is temporarily fixed to the outer surface of the inner liner, and then the intermediate membrane is disposed and permanently adhesion-fixed to the outer surface of the inner liner by hot pressing. Next, the adhesion member is temporarily fixed to the outer surface of the intermediate membrane, and then the outer shell is disposed and permanently adhesion-fixed to the outer surface of the intermediate membrane.
Accordingly, since two processes of temporarily fixing the adhesion member and two processes of hot pressing are required, the manufacturing process is complex and the manufacturing time increases. Also, as the adhesion member is temporarily fixed to one area of the inner liner and the intermediate membrane, a mutual adhesion force between the inner liner and the intermediate membrane is weak in an area to which the adhesion member is not fixed.
Thus, new gloves having the moisture permeable and waterproof properties and the excellent grip feeling need to be developed and a new method of easily manufacturing the gloves with low costs is required.

MODE FOR CARRYING OUT THE INVENTION

Categories of the present invention are classified into a glove intermediate membrane, a manufacturing method for the glove intermediate membrane, and gloves and a manufacturing method therefor. Since all of the invention of each of the categories include the new glove intermediate membrane in common, which is inserted between an inner liner and an outer shell, the overall present invention corresponds to one kind of invention.
Hereinafter, a basic constitution in accordance with the invention corresponding to each of the categories will be described, and then an embodiment of each of the inventions will be described in detail.
1. Glove intermediate membrane
A basic constitution of the glove intermediate membrane in accordance with the present invention includes first and second intermediate membranes that are inserted between the inner liner and the outer shell.
The first intermediate membrane has a glove shape made of a first material having moisture permeability and waterproof functions. Here, the ‘moisture permeability’ represents a function that discharges sweat generated from hands to the outside, and the ‘waterproof functions’ represent a function that prevents water or rainwater from being introduced into the inner liner. The first intermediate membrane may be made of a polyurethane-based material.
The second intermediate membrane is disposed on one of an inner surface and an outer surface of the first intermediate membrane and made of a second material having a melting point lower than that of the first material so that the first intermediate membrane is joined to one of the inner liner and the outer shell by heat supply. The second intermediate membrane has a glove shape. Here, the second intermediate membrane is constituted by a sheet shaped fiber assembly made of a thermal bonding material and have a plurality of voids disposed over an entire surface thereof. Here, as a gap between the voids is wider under a condition in which an adhesion force is sufficiently maintained, it is more desirable to secure the permeability. The second intermediate membrane may be made of modified polyester and manufactured by using a non-woven fabric manufactured in the form of a web.
The above-described first intermediate membrane is constituted by one pair of sheets, each of which has a plane shape of a glove, a second intermediate membrane is constituted by one pair of sheets overlapping the inside or outside of the first intermediate membrane, and an edge part of each of the first and second intermediate membranes excluding a wrist portion includes an edge joining part that is joined by heat supply. Accordingly, the first and second intermediate membranes are integrated with each other.
Hereinafter, first to third embodiments of the glove intermediate membrane in accordance with the present invention will be described in detail with reference to the drawings. A basic constitution of each of the embodiments is the same as described above. Hereinafter, a specific constitution of each of the embodiments will be mainly described.
As in FIGS. 3 and 4, a glove intermediate membrane 200 in accordance with the first embodiment further includes a third intermediate membrane 230 disposed on one of an inner surface and an outer surface of the first intermediate membrane 210 besides the above-described the first and second intermediate membranes 210 and 220. The third intermediate membrane 230 is made of a third material having a inciting point lower than that of the first material of the first intermediate membrane 210 so that the first intermediate membrane 210 is joined to the other of the inner liner and the outer shell of the first intermediate membrane 210. Here, the third intermediate membrane 230 may be made of the same material as that of the second intermediate membrane 220.
In detail, the first intermediate membrane 210 is constituted by one pair of sheets 211 and 212, each of which has a plane shape of a glove, the second intermediate membrane 220 is constituted by one pair of sheets 221 and 222 overlapping one of the inside and outside of the first intermediate membrane 210, and the third intermediate membrane 230 is constituted by one pair of sheets 231 and 232 overlapping the other of the inside and outside of the first intermediate membrane 210. Also, edge parts of the first, second and third intermediate membranes 210, 220, and 230 excluding wrist portions are joined by heat supply and integrated into an edge joining part 260.
As in FIG. 5, a glove intermediate membrane in accordance with the second embodiment includes a plurality of thermal joining materials 240 disposed over the entire inner surface of the first intermediate membrane 210 and made of a fourth material having a melting point lower than that of the first material of the first intermediate membrane 210 so that the first intermediate membrane 210 is joined to the inner liner by heat supply.
In detail, the first intermediate membrane 210 is constituted by one pair of sheets, each of which has the plane shape of the glove, and the second intermediate membrane 220 is constituted by one pair of sheets overlapping the outside of the first intermediate membrane 210. Also, the thermal joining materials 240 are distributed in the inner surface of the first intermediate membrane 210.
Also, the edge part of each of the first and second intermediate membranes 210 and 220 excluding the wrist portion are joined by heat supply and integrated into the edge joining part 260.
The thermal joining materials 240 are uniformly spaced at a predetermined space over the entire inner surface of the first intermediate membrane 210 and firmly joined to the inner liner. For example, the thermal joining materials 240 may be respectively disposed on consecutive vertices of a rectangle or a hexagon through a printing method. Alternatively, the thermal joining materials 240 may be uniformly applied to the surface of the first intermediate membrane 210 through a spray method. These thermal joining materials 240 may use the same kind of material as the first material of the first inteimediate membrane 210, which has a relatively low melting point. For example, when the first intermediate membrane 210 is made of a polyurethane-based material, each of the thermal joining materials 240 is also made of the same polyurethane-based material which has a relatively low melting point.
Meanwhile, although not shown in the drawings, unlike in FIG. 5, the first and second intermediate membranes 210 and 220 may replace their positions with each other, and the thermal joining material 240 may be disposed on the outer surface of the first intermediate membrane 210.
Alternatively, the glove intermediate membrane in FIG. 5 may be turned inside out to be used. Accordingly, the edge joining part 260 may be moved to the inside to make a clean outer surface and uniformly join the first intermediate membrane 210 to the outer shell.
Although a glove intermediate membrane in accordance with the third embodiment has a basic constitution that is the same as that of the second embodiment, each of a plurality of thermal joining tapes 250 having a viscosity is disposed on a position in which the thermal joining materials 240 is disposed. In detail, a bottom surface of the thermal joining tape 250 has a viscous material and is made of a fifth material having a melting point lower than that of the first material of the first intermediate membrane 210.
2. Manufacturing method for glove intermediate membrane
As in FIG. 7, a manufacturing method for a glove intermediate membrane in accordance with the present invention includes a sheet arrangement process of overlapping the first and second intermediate membrane sheets that basically constitute a raw material, a sheet cutting process of cutting the overlappingly arranged sheets in the plane shape of the glove, and an edge joining process of joining the edge part excluding the wrist portion of the cut sheet.
In detail, the raw material in the sheet arrangement process includes two first intermediate membrane sheets made of the first material having moisture permeability and waterproof functions and two second intermediate membrane sheets made of the second material having a melting point lower than that of the first material and disposed one of the inside and outside of each of the two first intermediate membrane sheets.
When the manufacturing method for the glove intermediate membrane in accordance with the first embodiment is described with reference to FIG. 4. in the sheet arrangement process, the two third intermediate membrane sheets 231 and 232 made of the third material having a melting point lower than that of the first material are further overlappingly disposed on the inside of each of the two first intermediate membrane sheets 211 and 212.
When the manufacturing method for the glove intermediate membrane in accordance with the second embodiment is described with reference to FIG. 5, in the sheet arrangement process, a plurality of thermal joining materials made of the fourth material having a melting point lower than that of the first material are disposed over the entire inner surface of each of the two first intermediate membrane sheets that are used in the sheet arrangement process.
When the manufacturing method for the glove intermediate membrane in accordance with the third embodiment is described with reference to FIG. 6, a plurality of thermal joining tapes made of the fifth material having a melting point lower than that of the first material are attached to the entire inner surface of each of the two first intermediate membrane sheets that are used in the sheet arrangement process.
Since the above-described glove intermediate membrane may be applied to various kinds of gloves, an independent product sales market may be formed. Also, although the glove intermediate membrane is greater in size than the gloves, since it is joined while firmly contacting the inner liner or the outer shell of the glove, it may be used regardless of the size of gloves.
3. Gloves
A glove in accordance with the present invention has a basic constitution including an inner liner having a glove shape; an outer shell surrounding the inner liner; a first intermediate membrane disposed between the inner liner and the outer shell and made of a first material having moisture permeability and waterproof functions; and a first joining part in which a second intermediate membrane made of a second material having a melting point lower than that of the first material and disposed on one of an inner surface and an outer surface of the first intermediate membrane allows the first intermediate membrane to join to one of the inner liner and the outer shell by heat supply.
Hereinafter, fourth to sixth embodiments of the glove in accordance with the present invention will be described in detail. A basic constitution of each of the embodiments will be the same as described above. Hereinafter, a specific constitution of each of the embodiments will be mainly described. Attached FIGS. 8 to 10 are cross-sectional views illustrating moisture permeability and waterproof functions while wearing the glove.
As in FIG. 8, a glove in accordance with the fourth embodiment includes a first joining part 261 in which a second intermediate membrane sheet disposed on the outer surface of the first intermediate membrane sheet 211 and made of the second material having a melting point lower than that of the first material allows the first intermediate membrane sheet to join to an outer shell 300 by heat supply. Also, a second joining part 262 in which a third intermediate membrane disposed on an inner surface of the first intermediate membrane sheet 211 and made of a third material having a melting point lower than that of the first material allows the first intermediate membrane sheet 211 to join to an inner liner 100 by heat supply is provided.
Accordingly, sweat 3 generated from a skin 1 is discharged to the outside sequentially through the inner liner 100, the second joining part 262, the first intermediate membrane sheet 211, the first joining part 261, and the outer shell 300. Also, although water 2 provided from the outside passes through the outer shell 300 and the first joining part 262, the water 2 may not pass through the first intermediate membrane sheet 211 having moisture permeability and waterproof functions and discharged to the outside again (refer to an arrow of a solid line). Here, since the first and second joining parts 261 and 262 are formed of the second and third intermediate sheets 221 and 231 having a plurality of voids by heat supply, the sweat 3 is smoothly discharged because the first and second joining parts 261 and 262 have enough voids (refer to an arrow of a dotted line).
Also, since the inner liner 100, the glove intermediate membrane 200, and the outer shell 300 are firmly joined while closely contacting each other, excellent grip feeling is provided.
As in FIG. 9, a glove in accordance with the fifth embodiment includes a first joining part 261 having the same constitution as that in the fourth embodiment and a third joining part 263 in which a plurality of thermal joining materials, which are disposed over the entire inner surface of the first intermediate membrane sheet 211 and made of a fourth material having a melting point lower than that of the first material, allows the first intermediate membrane sheet 211 to joint to the inner liner 100 by heat supply.
Accordingly, the sweat 3 generated from the skin 1 is discharged to a gap disposed in the third joining part 263. That is, the sweat 3 is discharged through a space disposed between portions in which the plurality of thermal joining materials 240 illustrated in FIG. 5 are thermally bonded.
As in FIG. 10, a glove in accordance with the sixth embodiment includes a first joining part 261 having the same constitution as that in the fourth embodiment and a fourth joining part 264 in which a plurality of thermal joining tapes, which are attached to the inner surface of the first intermediate membrane sheet 211 and made of a fifth material having a melting point lower than that of the first material, allows the first intermediate membrane sheet 211 to joint to the inner liner 100 by heat supply.
Accordingly, the sweat 3 generated from the skin 1 is discharged to a gap disposed in the fourth joining part 264. That is, the sweat 3 is discharged through a space disposed between portions in which a plurality of thermal joining tapes 250 illustrated in FIG. 6 are thermally bonded.
4. Manufacturing method for glove
A manufacturing method for the glove in accordance with the present invention includes sequentially stacking the inner liner disposed on the mold, the glove intermediate membrane in accordance with one of the first to third embodiments, and the outer shell, joining by heat-supply, and then separating the glove from the mold.
As in FIGS. 11 and 12, a manufacturing method in accordance with a seventh embodiment includes an inner liner coupling process in which the inner liner 100 is put onto a mold M having a glove shape; an intermediate membrane coupling process in which the above-described glove intermediate membrane 200 is put onto the inner liner 100; an outer shell coupling process in which the outer shell 300 is put onto the glove intermediate membrane 200; and a thermal bonding process in which the inner liner 100, the glove intermediate membrane 200, and the outer shell 300 are stacked and joined through at least one of a method for supplying heat from the outside of the outer shell 300 and a method for supplying heat from the mold M. After these series of processes are completed, the gloves are separated from the mold M to complete the glove manufacturing.
As in FIG. 12, the mold M used for manufacturing the glove has the glove shape in which fingers are sufficiently spaced and is made of a metallic material. It is desired that the mold M maintains a shape in which a thumb to a little finger have vertically standing shape so that the inner liner 100, the glove intermediate membrane 200, and the outer shell 300 are easily put thereon. Also, finger portions of the mold M, especially root portions of the fingers, are sufficiently spaced so that all of the inner liner 100, the glove intermediate membrane 200, and the outer shell 300 are uniformly joined.
In the inner liner or outer shell coupling process, the inner liner 100 and the outer shell 300 are made of a knitting fabric, and the inner liner 100 and the outer shell 300 are expanded to be put onto the mold M in each of the processes. When the glove intermediate membrane 200 is thermally joined while put onto the inner liner 100 or the outer shell 300, although a user excessively moves hands while wearing the glove, the glove intermediate membrane 200 may be prevented from being separated from the inner liner 100 or the outer shell 300 and damaged.
In the thermal bonding process, heat is supplied from the outside or the mold M to a surface of the outer shell to form the first to fourth joining parts 261 to 264 between each of the inner liner 100, the glove intermediate membrane 200, and the outer shell 300 as in FIGS. 8 to 10.
Here, an oven or an air-heating furnace providing hot air may be used as a heating device, and the surface of the outer shell 300 is pressurized in the heating process to uniformly thermal-bond and simultaneously decrease process time. Especially, when the outer shell 300 is made of a woven fabric, since a gap may be generated between the sewing line portion and the intermediate membrane 200, it is desired to pressurize the sewing line portion.
It is desired that power is supplied in the thermal bonding process and the previous process thereof to maintain the mold M at a predetermined temperature or more. Accordingly, the thermal bonding time may decrease, and also the glove intermediate membrane 200 is uniformly thermal-bonded to the entire inner surface of the outer shell 300.
As in FIGS. 13 and 14, a manufacturing method for a glove in accordance with an eighth embodiment, although it is basically the same as that of the seventh embodiment, is different in that, after the inner liner coupling process, a plurality of thermal bonding tapes 25( )are attached to the outer surface of the inner liner 100, and then the glove intermediate membrane excluding the thermal bonding tape 250 from the constitution of the glove intermediate membrane in accordance with the third embodiment in FIG. 6 is used. That is, the second intermediate membrane 220 constituting the glove intermediate membrane is disposed to the outer surface of the first intermediate membrane 210. Here, the thermal bonding tape 250 is made of a fifth material having a melting point lower than that of the first material of the first intermediate membrane.
The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the true spirit and scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
