Method of using a flexible band containing hook and loop fastener

Abstract

The hook and loop fastener comprises a first fastener portion provided with a fastener pile containing hooks or both hooks and loops. This first fastener portion is intended to cooperate with a second fastener portion provided with a fastener pile which contains loops or both hooks and loops. To protect each of the fastener piles of the fastener portions from being excessively loaded under compression each of the fastener portions is provided with at least one compression-resistant spacer or distance member arranged alongside the associated fastener pile. The thickness of each such spacer or distance member amounts to at most the height of the related fastener pile, preferably is however slightly less than such fastener pile height.

Description

BACKGROUND OF THE INVENTION

The present invention relates to separable fasteners or fastening devices, in particular to hook and loop fasteners, a flexible band equipped with such fasteners and a method of using such flexible band.

In its more particular aspects, the hook and loop fastener or fastening device of the present development is of the type comprising a first fastener portion provided with a fastener pile, for instance a fastener pile containing hooks or both hooks and loops. This first fastener portion is intended to cooperate with a second fastener portion which is provided with a fastener pile which contains loops or both hooks and loops.

It is well known in the art of hook and loop fasteners or fastening devices that such contain two flat fastener or closure portions each of which comprises a fastener pile. When these two flat fastener portions are brought into contact with one another by exerting thereat a slight mutual pressure these two flat fastener portions adhere to one another. These mutually engaging fastener portions are capable of withstanding quite appreciable forces when such forces are applied approximately parallel to the surface of the fastener portions. Both of the fastener portions can be again separated from one another by tearing them apart in a direction away from one another by accomplishing a lifting motion of one of the fastener portions relative to the other.

There are basically two types of hook and loop fasteners which are known. One type, for instance which has become widely known in the art under the trademark "VELCRO" provides the one fastener portion with a fastener pile which exclusively consists of hooks and the other fastener portion comprises a fastener pile which exclusively consists of loops. The other type of hook and loop fasteners or fastener devices provide both the fastener portions with an associated fastener pile which contains both hooks and loops. It is here specifically noted that the fasteners or fastening devices of the present invention can be of the one or of the other aforementioned types of hook and loop fasteners.

With the prior art hook and loop fasteners the fastener pile of the fastener portions constitutes a relatively fragile or delicate element. In particular, the hooks composed of a monofilament can permanently deform when exposed to repeated and pronounced compressive loads, for instance when such fastener hooks are pressed against a hard support or surface. Also with time the loops of the loop-type fastener pile can be pressed flat against their associated base or foundation fabric. In both cases such so-to-speak "aging" phenomenon leads to the undesirable result that both of the fastener portions gradually no longer tend to reliably engage with one another, and thus, with time no longer afford any sufficient mutual attachment or interconnection to one another. The same also holds true in those situations where a hook and loop fastener, whose fastener portions engage with one another, are exposed to compressive overloading or excess loads throughout a longer period of time.

SUMMARY OF THE INVENTION

Therefore with the foregoing in mind it is primary object of the present invention to provide a new and improved construction of a hook and loop fastener as well as a flexible band or strap equipped with such hook and loop fastener, which are not afflicted with the aforementioned shortcomings or drawbacks of the prior art.

Another important object of the present invention aims at the provision of a new and improved method of using a flexible band or strap equipped with the novel construction of hook and loop fastener.

Still a further significant object of the present invention is directed to the provision of a new and improved construction of hook and loop fastener or fastening device which improves upon heretofore known hook and loop fasteners in that the fastener pile of both fastener portions of the hook and loop fastener, whether these fastener portions are in their separated or released state or in mutual fastening engagement with one another, are extensively protected against compressive overloading so that the fastener piles cannot become damaged.

Yet a further notable object of the present invention relates to a new and improved construction of a hook and loop fastener as well as a flexible band or strap equipped with such new and improved hook and loop fastener, wherein there is afforded extensive protection of the fastener piles of the hook and loop fastener, particularly protection against excessive compressive loading of the fastener piles of the hook and loop fastener so that such hook and loop fastener and the flexible band or strap equipped with the same can be repeatedly used over prolonged periods of time and in fields of application where such hook and loop fastener otherwise would have the fastener piles quickly damaged due to such compressive loading.

Yet a further appreciable object of the present invention is to devise a novel construction of hook and loop fastener provided with means for protecting the fastener piles against compressive loading so as to prolong both the longevity and to beneficially extend the field of use of such hook and loop fastener.

Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the hook and loop fastener or fastening device of the present development, among other things, is manifested by the features that each of the fastener portions is provided with a spacer or distance member which is arranged alongside or adjacent the related fastener pile. The thickness or height of each such spacer or distance member at most amounts to the height of the associated fastener pile.

As alluded to above, the invention is not only concerned with the aforementioned novel construction of hook and loop fastener or fastening device, but further pertains to a flexible band or strap which is equipped with such novel hook and loop fastener. In its more particular aspects, this flexible band has opposed end regions and is provided at one of these end regions of such flexible band at one side or face thereof with one of the fastener portions. Spaced in the lengthwise or longitudinal direction of the flexible band there is provided at the other side or face of such flexible band the other of the fastener portions. The spacer or distance member of each of the fastener portions is flexible or pliant.

The invention also concerns a novel method of using such flexible band or strap in a winding apparatus for, for instance, winding-up substantially flat structures into a coiled product package upon a winding mandrel or winding-off or unwinding the coiled product package composed of the substantially flat structures. This flexible band or strap is used as a winding band or strap which is wound or coiled between the wound coils or layers of the substantially flat structures which are wound up upon the winding core to form a coiled product package or unwound from the coiled product package. This winding band or strap is releasably or detachably secured by means of the hook and loop fastener at the winding core or mandrel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Describing now the drawings, it is to be understood that to simplify the illustration of the drawings only enough of the construction of the winding apparatus for the winding-up of substantially flat structures into a coil product package and for unwinding the substantially flat structures from the coiled product package has been shown as needed to enable those skilled in the art to readily understand a possible field of use of the inventive flexible band or strap provided with the novel hook and loop fastener or fastening device. It is also to be expressly understood that although the invention will be described hereinafter in conjunction with a flexible band or strap and, specifically, a flexible band or strap which is used as a winding band for product packages formed of substantially flat structures, for instance printed products, such as newspapers, magazines, periodicals or the like, it should be clearly understood that the inventive hook and loop fastener or fastening device can be used in many other fields of application and particularly in those instances where also heretofore prior art constructions of hooks and loop fasteners have been employed. This is particularly inclusive of the garment or clothing industry including the footwear or shoe industry. Additionally, the inventive hook and loop fastener can be beneficially employed in further or other fields of application where heretofore that was not thought to be practical or possible, for instance for the releasable attachment of a tread sole to the inner sole of an article of footwear, such as a shoe or boot, or for the releasable attachment of a pedestal or socket of a heavy piece of equipment or apparatus at a predeterminate location or site. Further, it is to be observed, and as previously explained, that the invention also can be extended to such hook and loop fasteners or fastening devices wherein both fastener or closure portions contain the same type of fastener pile, namely a fastener pile which also contains both loops and equally hooks.

Turning attention now specifically to the exemplary embodiment of hook and loop fastener or fastening depicted in FIGS. 1 to 5 such will be seen to be affixed to a flexible band, strap or tape 10, for instance by being sewn or adhesively bonded therewith. Such hook and loop fastener comprises two fastener or closure portions 11 and 12 here shown to have an elongate configuration. The fastener portion 11 can be particularly well seen by referring to FIG. 2 and the fastener portion 12 by referring to FIG. 3. Each of the fastener or closure portions 12 and 13 possesses a base or substrate constituted, for instance, by a base or foundation fabric 13 which is provided with a related fastener pile. Specifically, in the exemplary embodiment under discussion the fastener portion 11 is provided, for example, with a hook pile 14 and the fastener portion 12 with a loop pile 15. It will be recalled, however, that each such fastener pile 14 and 15 can comprise both hook and loop elements, and by way of completeness it is also indicated that the hook pile, such as the hook pile 14 can be provided at the fastener portion 12 and the loop pile, such as the loop pile 15 can be provided at the fastener portion 11.

It is further to be noted, however, that the fastener piles 14 and 15 of both fastener or closure portions 12 and 13 do not occupy the entire width or crosswise extent of the associated base or foundation fabric 13, rather, in the exemplary embodiment under discussion, are divided into two strip-shaped fastener pile sections 14a, 14b and 15a, 15b,respectively, which here are shown to occupy the two marginal or edge regions of the associated base or foundation fabric 13 and which may possess the same pile section width, although such need not be so. From the illustration of FIGS. 2 and 3 it will be further recognized that between the fastener pile sections 14a, 14b and 15a, 15b there is secured a respective substantially strip or band-shaped spacer or distance member 16 upon the associated base or foundation fabric 13, for instance, by means of a suitable adhesive bond. Each such spacer or distance member 16 is formed of any suitable compression-resistant material and, specifically, for instance is fabricated from a sturdy or massive and flexible plastic band or strap. These spacer or distance members 16 may have the same width, although such is not absolutely necessary.

Continuing, and as will be further apparent from the illustration of FIGS. 2 and 3, each of the spacer or distance members 16 possesses a thickness or height which is advantageously slightly less than the thickness or height of the associated fastener pile 14 and 15. In the embodiment under discussion the thickness or height of each spacer or distance member 16 is less than the thickness or height of the related fastener pile 14 and 15 arranged alongside of or neighboring such spacer or distance member 16 by an amount which is sufficient in order to place into proper mutual engagement or releasable interlocking relationship the fastener piles 14 and 15 of both fastener portions 11 and 12, as also will be recognized by referring to FIG. 12.

In the arrangement of the hook and loop fastener or fastener device as depicted in FIG. 1 it will be seen that the fastener or closure portion 11, while leaving free a, for instance, rounded or curvilinear band tongue or end or end portion 17 (see also FIG. 4) is secured at the region of the end of the related flexible or pliant band or strap 10 at the one side or face thereof. On the other hand, the other fastener of closure portion 12 is secured at a spacing from the fastener or closure portion 11 at the other side or face of this flexible or pliant band or strap 10. In the embodiment under discussion the fastener portion 11 is also appreciably shorter than the other fastener portion 12, even though the drawing is not to scale. The reason for this construction and arrangement, as will be demonstrated more fully hereinafter, resides in the preferred exemplary field of use or application of this flexible band or strap 10.

Additionally it is to be observed that at the fastener portion 11 the spacer or distance member 16 is longer than the related fastener pile sections 14a, 14b and protrudes at both ends past such fastener pile sections 14a, 14b. The end region 16' of this spacer or distance member 16, both as shown in the arrangement of FIG. 4 and also in the arrangement of FIG. 5, is bevelled or tapered, in other words, has a sloped configuration which comprises a continually decreasing thickness or height so that it does not terminate in a step-like structure or abrupt transition or step. As a result, the illustrated flexible or pliant band 10 together with the fastener portions 11 and 12 can be wound up, for instance, upon a supply spool without there being formed any appreciable irregularities or uneven band portions.

Turning attention now to FIG. 6, there will be recognized an only schematically depicted wound product package 20 formed of substantially flat structures or products which have been wound upon a winding core or mandrel 21 with the aid of the flexible band or strap 10 serving as a winding band or strap. These wound-up substantially flat structures or products have not been specifically identified in FIG. 6 but have been designated by reference numeral 22 in FIG. 13 and are wound up in an imbricated product formation. This flexible band or strap, hereinafter generally referred to as the winding band or strap 10 when used for winding substantially flat structures or products, is payed-off or delivered during the product winding up operation from a supply roll or spool 23 and is guided between a pair of rolls or rollers 24 to the product package 20, this pairs of rolls or rollers 24 here constituting a pair of coacting braked rolls. The travel path of the winding band 10 has been indicated with the chain-dot line 25.

In the illustrated state of the winding apparatus of FIG. 6 the product package 20 is assumed to be full and thus no further substantially flat structures or products are infed to the winding core or mandrel 21 and the products 22 which have already been wound up on the product package 20. Moreover, the winding band or strap 10 has already been wrapped at least one additional time about the formed product package 20. The fastener portion 12 is secured to the winding band or strap 10 at the side or face thereof which faces away from the wound product package 20 and has a length which exceeds the length of the circumference of the wound product package 20. On the other hand, the other fastener or closure portion 11 is secured at the other side or face of the winding band or strap 10 which confronts the wound product package 20, so that only the end of the winding band or strap 10 which is still visible in the showing of FIG. 6 must be placed upon the previously already wound up additional winding band coil or convolution and slightly pressed thereagainst. In this way the entire wound product package 20 is reliably fixed against undesirable unravelling or falling apart.

An analogous operation occurs during unwinding or winding-off of the substantially flat structures or products from the wound product package 20 as shown in FIG. 7. It will be understood that the winding band or strap 10 is again guided between the rolls or rollers 24 and payed off or withdrawn from the wound product package 20 and now is wound up upon the driven supply roll or spool 23. Also in this case the end of the winding band or strap 10 which previously was secured to the winding core or mandrel 21 is now itself fixed to the full supply roll or spool 23 for the winding band or strap 10.

From the sectional view depicted in FIG. 8 there will be recognized that the core or core member 26 of the supply roll or roller 23 is somewhat stepped at the regions 26a bounding the side flanges or flange members 27, in order to relieve the fastener pile sections, which come to bear directly upon the core or core member 26 upon winding the winding band or strap 10 upon the supply roll 23, completely from the pressure of the following coils or windings. As to the windings or coils or convolutions which follow the first winding or coil or convolution such are constituted by the spacer or distance members 16 which come to bear directly upon one another and which extensively relieve the adjacently situated fastener pile sections from the pressure or compressive forces exerted by the remaining windings or coils or convolutions of the winding band or strap 10.

By referring to FIG. 9 it will be apparent that when the winding band or strap 10 passes between the rolls or rollers 24 with one of the fastener portions 11 or 12, such fastener portions are extensively relieved of the compressive load or action which prevails in the roll gap or nip between such rolls 24, since this compressive action is absorbed or taken up by the spacer or distance members 16.

Instead of providing a remotely located supply roll or roller 23 for the winding band or strap 10 it would be possible to integrate the supply roll or roller, as generally indicated by reference character 23', in the form of a spool body 23" within the winding core or mandrel 21 in a manner known to the art from, for instance, the commonly assigned U.S. Pat. No. 4,532,750, granted Aug. 6, 1985, and also from the commonly assigned copending U.S. application 07/162,949, filed Mar. 2, 1988, and entitled "Package Support Device for the Intermediate Storage of Wound-Up Printed Products, such as Newspapers, Periodicals and the like", to which reference may be readily had and the disclosures of which are incorporated herein by reference. The spool body 23" of the supply roll or roller 23' may be arranged coaxially with respect to the winding core or mandrel 21 or axially parallel thereto and the winding core or mandrel 21 has an opening, generally represented by reference character 21', which may be closed by a cover, and through which there extends the winding band or strap 10.

The winding band or strap 10 can be releasably connected by means of the hook and loop fastener at the related winding core or mandrel, namely at the winding core or mandrel 21 at which there is wound up or unwound the product package 20 or at the winding core or mandrel of the internally located supply roll or roller 23', as the case may be. There may be then secured or positioned at the package winding core 21 or at the winding core of the internally located supply roll or roller 23' one of the fastener portions 11 located at an end region of the winding band or strap 10 and at a side of such winding band or strap 10 which confronts such winding core and which is situated in close proximity to the winding core there is located the other of the fastener portions 12 which is then secured to the one fastener portion 11. In so doing, the end region of the winding band or strap 10 which is located in close proximity to the winding core may be wrapped a number of times about the winding core and such winding band or strap 10 is then secured to itself by means of the hook and loop fastener.

FIG. 10 illustrates in side view a wound product package 20 which has been fixed or held together by means of the associated winding band or strap 10. It will be seen that the band tongue or end portion 17 located at the end of the winding band or strap 10 which is disposed remote from the winding core or mandrel 21 has been reinforced or stiffened by the extension or end portion 16' of the spacer or distance member 16 which protrudes beyond the fastener or closure portion 11 (see also FIG. 4), and thus, outwardly depends or protrudes from the outer surface of the wound product package 20. Consequently, the band tongue or tongue portion 17 forms a convenient manipulating facility or tab which facilitates separation or detachment of the fastener portions 11 and 12 from one another.

From the front view of the wound product package 20 as depicted in FIG. 11, it will be observed that the length of the fastener pile sections 15a and 15b of the fastener portion 12 (see also FIG. 5) considerably exceeds the length of the not particularly visible coacting fastener or closure portion 11. A part of the fastener pile sections 15a and 15b are thus freely accessible from the outside. However, even if the wound product package 20 is supported at its circumference or outer surface at the floor or other support structure or is rolled along such floor or support structure, these fastener pile sections 15a and 15b are not damaged because the here intermediately arranged spacer or distance members 16 extensively protect the fastener pile sections 15a and 15b from the compressive loads exerted by the inherent weight of the wound product package 20.

Finally, from the showing of FIG. 13 there will be recognized a further advantageous characteristic of the here exemplary described winding band or strap and the spacer or distance members 16 which are provided between the fastener pile sections 15a and 15b and the fastener pile sections 14a and 14b.

The spacer or distance members 16 which, in the present exemplary embodiment and as previously explained, are formed of a massive or sturdy however flexible or pliant plastic band or strap member and are provided at their ends or end regions 16' (compare also FIGS. 4 and 5) with a continually decreasing thickness, thus form an ideal reception facility for the insertion or introduction of a flat, spatula-like or knife-like tool 28 by means of which there can be advantageously initiated the operation of separating or releasing the hook and loop fastener without damage to the fastener pile sections.

Although in the described exemplary embodiment the fastener or closure portion 12 provided, for instance, with the loop pile sections 15a and 15b is longer than the fastener or closure portion 11 provided with the hook pile sections 14a and 14b, it is of course also possible to make both fastener or closure portions 11 and 12 of the same length, or, as previously indicated, to equip the fastener or closure portion 11 with the loop pile and the other fastener or closure portion 12 with the hook pile.

Also the arrangement of each of the spacer or distance members 16 is accommodated in the described example to the intended field of application. Yet, for the same field of application or use it would also be possible to secure two spacer or distance members or strips at the marginal or edge regions of the flexible band or strap 10 and to occupy the intermediate space between such mutually spaced spacer or distance members with a single fastener pile section. In this connection it need only be conceptually visualized that in the arrangement of, for instance, FIG. 12 the elements 16 then constitute the coacting fastener portions provided with the fastener piles and the there laterally situated fastener portions 11 and 12 then constitute spacer or distance members which straddle the intermediately situated fastener portions.

In the event that the fastener portions of the proposed hook and loop fasteners should have imparted thereto a form or shape which deviates from an elongated form or shape, owing to the contemplated field of application, then of course the form or shape of the associated spacer or distance members and the fastener pile sections must be appropriately accommodated to such field of application. If, for instance, both of the fastener or closure portions are of the same size, and possess a circular or quadratic configuration and should be anchored to a fixed planar or flat substrate, then it is advantageous to provide at the marginal regions along the entire circumference of the fastener portion a strip defining the spacer or distance member which, if desired, can be augmented at the central region by a further spacer or distance member, whereas the surface which is left free of the circumferential spacer or distance strips is then occupied with one or a plurality of fastener pile sections.

While there are shown and described present preferred embodiments of the invention, it is to be distinctly understood that the invention is not limited thereto, but may be otherwise variously embodied and practiced within the scope of the following claims. ACCORDINGLY,
