Description

FASTENING SYSTEM
BACKGROUND OF THE INVENTION
Field of the Invention:
This invention relates to the field of nonmetallic, interlocking fasteners, more particularly to pressure type interlocking fasteners. Description of the Prior Art:
Interlocking nonmetallic fasteners generally comprise two types. One type of interlocking fasteners is commonly known as a "slide fastener" which consists of two members each with alternating ridges and cavities. The two members are joined together as may be seen in U.S. Patent No. 2,878,541 by inserting the ridge of one member into the cavity of the other member. This type of interlocking fastener prevents the members from planar sliding. However, perpendicular movement is not prevented. A second type of nonmetallic interlocking fastener is commonly called a "zipper" fastener as disclosed in U.S. Patent Nos, 1,776,847, 1,801,324 and 2,018,099. It consists of two interlocking members that require the assistance of a slide to force the two members together. Planar and perpendicular movement are prevented, but the members cannot be interlocked without the assistance of the slide device.
The pressure type devices are commonly known as "VELCRO" type devices. Generally, they consist of two members that are joined together by pressure. One member has multiple plastic hooks which latch onto the multiple loops of plastic or fabric on the second members. When the members are joined their planar members are joined, their planar movement is restricted and their perpendicular movement is somewhat less restricted. However, such type devices are not designed to handle heavy loads over long periods of time or severe vibrations and they have a tendency to lose their holding capability and wear over time.
The usefulness of a metallic interlocking apparatus which joins its members by pressure, has longer useful life and can support heavy loads is greatly desired. It would also be desirable if the apparatus can be unlocked without the aid of a tool and without destroying the members. The fastening system of the instant invention is designed to overcome the all the problems of the prior art devices.
SUMMARY OF THE INVENTION
The fastening system of the instant invention comprising:
(a) at least two flexible members variable sizes; each member comprising:
(1) a flexible strip,
(2) a flexible burr.
(b) a plurality of equally spaced flexible burrs, with a top and a foot, on each flexible strip projecting approximately perpendicular from and integral with the flexible strip, including:
(1) a spherically formed top,
(2) a conically formed body with a top and bottom, median to the top and the foot of the burr, with a narrow neck at the top of the body integral with the spherical top and a wider spherical framed bottom integral with the foot, the outside surface of the body tapered from the neck to the spherical bottom,
(3) a narrow cylindrically foot integral with the body of the burr and the flexible strip; and
(4) a plurality of burr seating cavities alternating with the burrs and corresponding to the shape of the burr for receiving and holding the burrs from each flexible strip when forced together.
The flat surfaces of the two flexible strips are attachable to other devices. The devices are joined together by pressing the burrs of are flexible strip into the cavities of the other flexible strip. Once interlocked, the devices are unable to make a planar move and a perpendicular move to come apart without the assistance of a removal device. The flexible strips are formed from plastic or fabric. The flexible burrs are formed from plastic.
The various features, advantages, or other uses of the present invention will become more apparent, by referring to the following detailed description and drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a plan view of the instant invention engaged;
Figure 2 is a side sectional view of the instant invention with a portion of the burrs interlocked and a portion disengaged; and
Figure 3 is an end sectional view of the instant invention engaged.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Throughout the following description and drawing, identical reference numbers are used to refer to the same component shown in multiple figures of the drawin .
Referring now to Figures 1 , 2 and the fastening system 1 of the instant invention comprises at least two flexible members 2 and 3. Each flexible member 2 and 3 has a flexible strip 4 and 4' and a plurality of flexible burrs 5. Also, each flexible member has a plurality of burr seating cavities 6 alternating with the burrs and corresponding in shape to a burr 5. Further, each member has a common attachment means 10 for attaching to devices (not shown) .
Each flexible strip 4 and 4' is a flat plastic or fabric sheet of variable sizes. The strip acts as a base 7 for multiple burrs 5 which are integral to one surface 8 and 8' of the base 7 and 7'. The second surface 9 and 9' or attaching surface attaches to other devices {not shown) by an attachment means 10 and 10' such as an adhesive commonly know to those in the trade. Each flexible burr 5 has a top 11, a body 12, and a foot 13. The top 11 of the burr δ is a spherically formed solid head 14 which his integral to the body 12 at a narrow neck 15. The body 12 is a conically formed solid stem 16 median between the top 11 and the foot 13. The body 12 has a top 17 and a bottom 18. The top 17 of the body 12 is narrow and integral with the spherical head 14. The bottom 18 of the body 12 spherical and integral with the cylindrical foot 13.
The body 12 tapers from the narrow neck 15 of the top 17 to the wider spherical bottom 18. The spherical bottom 18 narrows to integrate with the cylindrical foot 13.
The cylindrical foot 13 is integral to the burr body 12 at one end and the strip base 7 at the other end.
The flexible burr 5 is made of a solid plastic or the like. It projects approximately perpendicular from the base 7.
Each burr seating cavity 6 is located on the burr surface 8 of the base 7 and are. There are a plurality of cavities 6 alternating with the burr 5. The cavity 6 is formed to the corresponding shape of the burr 5 of the mating flexible member 2 or 3.
Each flexible member 2 and 3 has a surface 9 and 9' which attaches to some device or item {not shown). This surface 9 and 9* is usually provided with an attachment means 10 which is commonly an adhesive or the like.
In use, each flexible member 2 and 3 is attached to a device (not shown) at the attachment surface 9 by the attachment means 10. After, the flexible members 2 and 3 are secure on the devices, the flexible members 2 and 3 are pressed together with the flexible burrs 5 the first flexible member 2 engaging the burr seating cavities 6 of the second flexible member 3 and the burrs 5 of the second flexible member 3 engaging the burr seating cavities 6 of the first flexible member 2. The fastened device remain firmly in position in most conditions. When the devices need to be separated, the first flexible member 2 is pulled from the second flexible member 3 without the aid of a tool .
Having, thus described the invention, what is claimed is:
