The present subject matter relates generally to adaptive clothing incorporating magnetic fasteners.
Adaptive clothing is clothing that is specifically designed to facilitate a user's ability to dress when the user has diminished physical capability or dexterity generally required to manipulate features of clothing such as buttons. Adaptive clothing has been designed for people with such conditions as arthritis, oedema, Alzheimer's disease, stroke, spinal cord injury, cerebral palsy, and brain injury. Adaptive clothing includes adaptations to make clothing look conventional. Jumpsuits can be used to simulate a combination of shirt and pants. Garments that need to be opened in the back may be made to appear as standard, front-opening garments.
Structure in adaptive garments may be particularly adapted to address specific problems. Length of various sections of clothing may be increased in order to accommodate wheelchair users, for example. Clothing may be designed to be removed easily and quickly for users with incontinence. The clothing may also be designed to accommodate incontinence aids discreetly and comfortably. For users who have lost fine motor skills due to Parkinson's Disease or arthritis, for example, buttons and zippers have been replaced by magnets or hook and mesh fasteners, often referred to by the trademark Velcro®.
Using conventional clothing, the wearer must manipulate each button through a button hole. This manipulation requires a degree of manual dexterity which is beyond the capabilities of many wearers subject to the medical conditions discussed above. In adaptive clothing, the button may be affixed to the outer surface of the garment. This gives the appearance that the button is secured to a conventional “button side” and has come through a buttonhole. In order to close a garment, a user places one side over the other such that magnets or hooks and mesh are in registration and press them together to close the garment.
Different varieties of magnetic closures have been introduced in adaptive clothing. Closure simply requires placing opposite magnets, for example, in registration. Designing the closure members in adaptive clothing requires optimization of strength of the closure, simplicity in construction, and ease-of-use for the user. The prior art is discussed primarily in the context of closures which replace a button. In one form a first portion, an upper front facing, is secured to a second portion, a lower front facing. Buttons are affixed to an upper layer to give the appearance of being fastened to the lower front facing and having come through button holes. The buttons may be attached to a placket.
U.S. Pat. No. 9,210,953 discloses a system in which a button is secured on an outer surface of an upper front facing. Three layers, an outer layer, an inner layer, and a lower layer are formed by folding an end of the upper front facing back over itself. These layers define one chamber that encloses thread on a lower surface of a fabric layer having an upper surface to which a button is attached. A magnet is disposed in a second chamber. The necessity of working with folded over sections creates difficulty in maintaining alignment of the folds in order to create uniform chambers. The complexity of this construction requires a higher level of skill of sewing machine operators and increased time and cost in manufacturing.
U.S. Pat. No. 9,717,293 discloses a magnetic fastener that permits existing garment buttons to be retrofitted for use by persons having diminished motor abilities. The magnetic button system comprises a button cover received over an existing button and having a magnet housed therein. The magnet is attracted to a magnetic or ferromagnetic element on a button hole engagement member received in a button hole of an existing garment. A separate button hole engagement member must be provided. The upper front facing will not be flush with the lower front facing because an adapter must be placed on the existing button.
U.S. Pat. No. 9,572,386 discloses a magnetic closure for clothing with non-magnetic backing. A flat, round magnet is inserted into a non-magnetic metal “cup” and enclosed entirely within a square, thin laminate covering. One flat surface of the magnet is exposed, and the opposite flat surface of the magnet is set against the inner surface of the non-magnetic metal cup. The non-magnetic metal cup serves to block or reduce the magnetic force of the surface of the flat, round magnet set against the inner surface of the cup. Such magnet, cup and laminate assemblies with exposed magnet surfaces of opposing polarities can be sewn or stitched on opposing sides of garment or clothing openings and used to close or fasten the garment or clothing utilizing magnetic force. The metal cup must be of the same size as the magnet, adding to the complexity of construction. The laminate covering is thin, e.g.,<1 mm. It is simply sewn to a surface and is not part of a particular assembly.
U.S. Pat. No. 9,392,829 discloses a device for magnetic clasping for a clothing accessory including at least one permanently magnetized assembly arranged at one end of one surface of the accessory. A plurality of ferromagnetic elements are arranged longitudinally on the other surface at the opposite end thereof. The magnetized assemblies of one surface may be laterally displaced to a position on the other surface. A plurality of adjustment positions of the surfaces are obtained relative to the position of the magnetized assemblies and ferromagnetic elements, representing a plurality of possible tightness levels. This construction is complex. It is not suitable for use in a placket. In a placket, two magnetic closure elements should not have a plurality of adjustment positions.
Briefly stated, in accordance with the present subject matter, adaptive clothing is provided in which magnetic members engage to magnetically fasten a lower front layer and an upper front layer. A magnet is provided in a container. The container comprises a housing for the magnet and a base extending beyond the boundaries of the housing. Extremities of the base are sewn to the fabric. The use of the container provides a simplified way of securing the magnet.
A first magnetic member is encapsulated in a housing. The housing is secured to an interior surface of the upper front layer. A second magnetic member is placed in an interior surface of the lower front layer. A button or other component is secured to the exterior side of the upper front layer to provide the appearance of a buttoned placket.
The placket may be constructed as a separate unit. The placket may be attached to the garment in a separate operation. This allows construction of the placket without having to manipulate the entire garment. In adaptive clothing, buttons are attached so that one side of a garment, such as a shirt, becomes an upper body front for male garments and attached so that the other side becomes the upper body front for female garments. Division of labor in flexibility in the manufacturing process is facilitated. An inventory of plackets may be maintained separately from an inventory of unfinished shirts. A single inventory of plackets may be maintained for two different models of shirts, i.e., male and female.
By constructing the placket separately, it is not necessary to manipulate an entire garment at the same time.
The present subject matter may be further understood by reference to the following description taken in connection with the following drawings:
The shirt 3 comprises a number of standard components. The outside layer of the front of the shirt 3 is called the upper body front 10. The shirt 3 has a sleeve 8. The upper body front 10 is the layer in which buttonholes are formed in conventional clothing. In adaptive clothing, buttons 12 are fixed to a placket 14 on the upper body front 10. Simulated buttonholes 16 are sewn at locations of each button 12. This arrangement gives the appearance that the buttons 12 have come through buttonholes in the placket 14. In conventional clothing, buttons 12 are fixed to a lower body front 18. An interior side of the upper body front 10 is the upper front facing 20. An interior side of the lower body front 18 is the lower front facing 24. The present subject matter may also be used in a cuff 26. References to the placket 14 also describe the cuff 26 except where logically impossible.
One end on the perimeter of the cuff 26 is analogous to the upper body front 10, and the other end of the parameter is analogous to the lower body front 18. A cuff sewing line 31 attaches the cuff 26 to the sleeve 8. The cuff sewing line 31 is analogous to the sewing line 28. In most embodiments, a sewing line 29 is not used.
In one preferred form, the placket 14 is formed separately from the shirt 3. The placket 14 is attached to the upper body front 10 and along a sewn line 28. An edge sewn line 29 is provided substantially parallel to the sewn line 28 on an opposite side of the buttons 12. In this manner, the placket 14 may be formed without manipulation of the entire shirt 3. Also, the placket 14 may be attached to either side of the shirt 3. Consequently, only one inventory of plackets needs to be maintained for assembly of men's and women's shirts. This construction is further discussed with respect to
In conventional garments, buttons are attached to one of two front facings for male garments and attached to the other front facing for female garments. The placket 14 may be selectively attached to the “male” side of the shirt or the “female” side of the shirt. Division of labor in flexibility in the manufacturing process is facilitated. An inventory of plackets 14 may be maintained separately from an inventory of unfinished shirts. A single inventory of plackets 14 may be maintained for two different models of shirts, i.e., male and female.
The magnet 90 is selected on the basis of strength of magnetic attraction, size, and cost. It is important for the lower fastener 34 and the upper fastener 32 to keep the shirt 3 closed while still being easily separated from each other by the user 1. Additional factors include the thickness of the fabric 4. The coefficient of friction of the fabric 4 is significant since the upper body front 10 and lower body front 18 can slide apart. Silk will have a relatively low coefficient of friction, while flannel will have a relatively high coefficient of friction.
The housing 76 may comprise any of a number of materials. Optimization for material selection takes into account strength, ease of penetration by a sewing needle or other means of fastening, and flexibility. Many different polymeric materials may be used. The base 80 is fixed to the lower front facing 24 (
The placket 14 comprises the section 52 of
The upper magnet assembly 74 is secured to the interior section 104. The upper magnet assembly 74 is disposed between the interior section 104 and the button section 102. In this embodiment, the housing 76 comprises a container 106. The container 106 preferably includes the base 80 and the cap 82. Alternatively, as illustrated in
The button 12 is secured to the button section 102 by button stitches 120. The button section 102 ends at an upper edge 130. The interior section 104 ends at a lower edge 132. The lower edge 132 is preferably in registration with the upper edge 130. In one preferred form, the upper edge 130 and the lower edge 132 are not fastened together prior to fastening to the shirt 3.
In order to attach the placket 14 to the shirt 3, a first facing 140 is placed between the button section 102 and the interior section 104 and projects into the placket 14 past the upper edge 130 and the lower edge 132. The first facing 140 will generally be an upper front facing. Additionally, an optional lining 142 may be placed in registration with the first facing 140. These components are secured by edge stitching 148. The edge stitching 148 may form the sewn line 28 of
The end assembly 160 comprises an end fabric piece 164. The end assembly 160 is folded on an end fold line 170. A portion of the end fabric piece 164 on one side of the end fold line 170 comprises an end upper section 172. An end interior section 174 is a portion of the end fabric piece 164 on the side of the end fold line 170 which will face the body of the wearer 1.
The lower fastener 34 comprises a lower magnet assembly 180 which is secured to the end upper section 172. The lower magnet assembly 180 is disposed between the end upper section 172 and the end interior section 174. The lower magnet assembly 180 includes a lower magnet 182. In this embodiment, the lower magnet assembly 180 comprises a container 188. In this embodiment, the container 188 is a rectangular parallelepiped. The container 188 is secured to the end upper section by a first sewing stitch 194 and a second sewing stitch 196. The first and second sewing stitches 194 and 196 go through the container 188. Additionally, a third sewing stitch 195 and a fourth sewing stitch 197 are provided to complete a perimeter around the magnet assembly 180.
In order to attach the end fabric piece 164 to the shirt 3, an opposite end of the first facing 140 is placed between the end upper section 172 and the end interior section 174 and projects into the end fabric piece 164 past an end upper section edge 176 and an end interior section edge 178. The first facing 140 will generally be an upper front facing. Additionally, the optional lining 142 may be placed in registration with the first facing 140. These components are secured by edge stitching 198. Fold stitching 200 is provided at an opposite end of the lower magnet assembly 180.
In
By constructing the placket 14 or the end assembly 160 separately, it is not necessary to manipulate the entire shirt 3 at the same time. An inventory of plackets 14 or end assemblies 160 may be maintained separately from an inventory of unfinished shirts. A single inventory of plackets may be maintained for two different models of shirts, i.e., male and female.
In the shirt 3, buttons 12 are attached so that one side of the shirt 3 becomes the upper body front 10 for male garments and attached so that the other side becomes the upper body front 10 for female garments. The placket 14 and the end assembly 160 may each be selectively attached to the “male” side of the shirt 3 or the “female” side of the shirt 3.
