This invention relates generally to drawstrings for use in apparel and other objects, and, in particular, to a hidden drawstring assembly for use in apparel and other objects.
Drawstrings are well known for closing or tightening items such as articles of apparel and duffle bags. When drawstrings are used on a hood of a coat or jacket, for example, the hanging drawstring can be cumbersome and an annoyance, and may create a safety issue due to the drawstring getting caught in or on another object. This can be especially dangerous for children.
It is an object of the present invention to provide a hidden drawstring assembly that reduces or overcomes some or all of the difficulties inherent in prior known devices. Particular objects and advantages of the invention will be apparent to those skilled in the art, that is, those who are knowledgeable or experienced in this field of technology, in view of the following disclosure of the invention and detailed description of certain preferred embodiments.
The principles of the invention may be used to advantage to provide a hidden drawstring assembly that can be used to tighten a drawstring, and which allows the drawstring to be hidden, thereby preventing free ends of the drawstring from being exposed and minimizing the danger associated with free or loose drawstring ends.
In accordance with a first preferred embodiment, a hidden drawstring apparatus includes a housing and a rotatable hub positioned within the housing. The hub is configured to receive an end of a drawstring to be wound about the hub. A handle assembly is rotatably connected to the housing. A drive member has a first end connected to the handle assembly and a second end connected to the rotatable hub.
In accordance with another preferred embodiment, a hidden drawstring apparatus includes a housing having a first aperture and a second aperture. A rotatable hub is positioned within the housing. A drawstring extends through the first aperture in the housing and has a first end secured to the hub. The drawstring is wound about and unwound from the hub as the hub rotates. A handle assembly is rotatably secured to an exterior of the housing. A drive member extends through the second aperture in the housing and is connected at a first end thereof to the handle assembly and at a second end thereof to the hub. The drive member transmits a rotational force applied to the handle assembly to the hub.
In accordance with a further embodiment, a hidden drawstring apparatus includes a housing having a first portion, a second portion releasably secured to the first portion, a first aperture, and a second aperture. A rotatable hub is positioned within the housing. A drawstring extends through the first aperture in the housing and has a first end secured to the hub. The drawstring is wound about and unwound from the hub as the hub rotates. A handle assembly is rotatably connected to the housing and includes a handle housing, a base portion secured to the handle housing, an arm pivotally secured to the base portion, and a drive member. The drive member has a first end connected to the arm and a second end connected to the rotatable hub, and extends through the second aperture in the housing. The drive member has a first end connected to the handle and a second end connected to the hub. The drive member is configured to transmit a rotational force applied to the handle to the rotatable hub.
Substantial advantage is achieved by providing a hidden drawstring assembly. In particular, certain preferred embodiments of the present invention provide an apparatus that allows a drawstring to be tightened, while keeping a free end of the drawstring concealed. This is highly advantageous since it prevents the free end from being exposed, minimizing the danger of the drawstring getting caught or snagged on or in another object. This is especially advantageous for use on children's apparel.
These and additional features and advantages of the invention disclosed here will be further understood from the following detailed disclosure of certain preferred embodiments.
The figures referred to above are not drawn necessarily to scale and should be understood to provide a representation of the invention, illustrative of the principles involved. Some features of the hidden drawstring assembly depicted in the drawings have been enlarged or distorted relative to others to facilitate explanation and understanding. The same reference numbers are used in the drawings for similar or identical components and features shown in various alternative embodiments. Hidden drawstring assemblies as disclosed herein would have configurations and components determined, in part, by the intended application and environment in which they are used.
The present invention may be embodied in various forms. A preferred embodiment of a hidden drawstring assembly 10 is shown in
A drawstring 14 extends about a periphery of hood 12, with a first end 16 (not visible here) of drawstring 14 secured to drawstring assembly 10 and a second end 18 of drawstring 14 secured to hood 12 by stitching or other suitable means. Drawstring 14 is concealed within hood 12. In the illustrated embodiment, drawstring 14 is located in a sleeve 19 formed in hood 12. Sleeve 19 may be formed by folding over and securing an edge of hood 12 by stitching or other suitable means. In another embodiment, sleeve 19 may be formed by a pair of opposed lines of stitching extending along the edge of hood 12. In yet other embodiments, a strip of material may be secured to hood 12 by stitching or other suitable means to form sleeve 19.
To tighten drawstring 14 about hood 12, the user turns an arm of a handle assembly 20 on drawstring assembly 10 to wind drawstring 14 within drawstring assembly 10 as described in greater detail below. Drawstring 14 is advantageously hidden within hood 12 and drawstring assembly 10 such that its ends do not hang free both when drawstring is tightened and when it is in its loose configuration, thereby minimizing any risk of the drawstring getting caught on another object.
It is to be appreciated that in certain preferred embodiments, an additional drawstring assembly 10 can be provided on the other side of hood 12, with second end 18 of drawstring 14 wound within the additional drawstring assembly 10 rather than being secured directly to hood 12.
Drawstring assembly 10 is seen in greater detail in
A plurality of apertures 38 are formed in wall 32 of first portion 24. A plurality of pairs of slots 40 are formed in wall 36 of second portion 26. Each pair of slots 40 extends axially inwardly from an axially exterior edge of wall 36 to define a flexible arm 42. A projection 44 is formed on a radially outward surface of each flexible arm 42. Each projection 44 is received in a corresponding aperture 38 when second portion 26 is nested within first portion 24. Flexible arms 42 move radially, allowing projections 44 to be released from engagement with apertures 38. To separate first portion 24 and second portion 26 from one another, a user simply presses projections 44 radially inwardly with their finger or a pin, rod or other suitable member, thereby releasing projections 44 from engagement with apertures 38, allowing first portion 24 and second portion 26 to be pulled apart from one another. A second aperture 46 is formed in a central portion of an axially outward wall 48 of first portion 24. A plurality of locking apertures 50 is disposed about second aperture 46.
A hub 52 is positioned within second portion 26 and includes a drive pin seat 54. As seen more clearly in
It is to be appreciated that in other embodiments, slots 40, flexible arms 42 and projections 44 can be positioned on first portion 24 with apertures 38 formed in second portion 26. In the illustrated embodiment, housing 22 and, therefore, first portion 24 and second portion 26, are substantially cylindrical. However, it is to be appreciated that other shapes of housing 22 are considered to be within the scope of the present invention.
Handle assembly 20, seen in
Arm 76 may be pivotally secured to base portion 74 by way of a pin 78 extending through an aperture 80 in a first end 82 of drive pin 68. Drive pin 68 extends through an aperture 84 in base portion 74 and through an aperture 86 in handle housing 70. A second end 88 of drive pin 68 extends through second aperture 46 in first portion 24 of housing 22 and is received in drive pin seat 54 of hub 52.
A pair of pins 90 extends outwardly from arm 76. Pins 90 are received in notches 92 formed in walls of recess 77. In a preferred embodiment, pins 90 are spring-loaded such that they are biased outwardly into engagement with notches 92 when arm 76 is folded into recess 77. Thus, in a non-operating condition, arm 76 is locked in place with respect to base portion 74. A release button 94 in arm 76 is connected to spring-loaded pins 90 such that depressing release button relieves the biasing action on pins 90 and allows arm 76 to be pivoted outwardly from base portion 74. It is to be appreciated that in certain preferred embodiments a single pin 90 can be provided on arm 76.
A first end 96 of a spring-loaded locking pin 98 extends through an aperture 100 in base portion 74. Locking pin 98 extends through an aperture 102 in handle housing 70, with a second end 104 of locking pin 98 extending through any one of locking apertures 50 in first portion 24 of housing 22 into hub 54. Second end 104 abuts against interior walls 64 of hub 54 to prevent rotation of hub 54 and unwinding of drawstring 14 when handle assembly 20 is in a locked condition. The spring 99 biasing pin 98 outwardly is contained within handle housing 70. When arm 76 is folded inwardly into recess 77 of base portion 74, arm 76 engages first end 96 of locking pin 98, forcing it inwardly such that second end 104 is received in a locking aperture 50 with which it is aligned. The engagement of locking pin 98 within a locking aperture 50 fixes handle assembly 20 with respect to housing 20. When arm 76 is folded outwardly from base portion 74 into its operating position, locking pin 98 springs outwardly out of engagement with the locking aperture 50. In this condition, handle assembly 20 can be rotated, allowing drawstring 14 to be wound about hub 52. After arm 76 has been rotated a sufficient amount to place drawstring 14 in a desired tightened position, arm 76 is folded back into recess 76, thereby depressing locking pin 98 such that its second end 104 engages a corresponding locking aperture 50.
A plurality of pins 105 extend outwardly from base portion 74 and are received in corresponding recesses 107 formed in handle housing 70, thereby securing base portion 74 to handle housing 70. Pins 105 may include barbs 109 on ends thereof, which are received in recesses 110 formed in the wall of handle housing 70. A pin, rod or other suitable member may be inserted into recesses 110 to release barbs 109 and pins 105, allowing base portion 74 to be separated from handle housing 70. As seen in
