Embodiments described herein generally relate to fastener devices.
Fastener devices may be used to couple pieces of material to one another.
The disclosure will be understood more fully from the detailed description given below and from the accompanying drawings of various embodiments of the disclosure. The drawings, however, should not be taken to limit the disclosure to the specific embodiments, but are for explanation and understanding only.
A fastener device may be used to fasten two pieces of sturdy cloth together, such as on pants, shorts, backpacks, belts, or climbing equipment. The fastener device may be installed with only a sharp object, such as an awl, and without sewing. The fastening device includes potential energy wells which keep the fastener device flush, minimizing possible catching on foreign objects. The fastener device spreads its load over two contact points in both a receiving aperture and on fabric in which it is installed. The two contact points (at each of both ends) of this fastener may lead to a much more even force distribution around a waistband. This may increase the user's safety by keeping them more comfortable and able to concentrate on the work at hand.
The fastener device 100 is generally symmetric across the x-axis with a generally S-shaped portion on either side of the x-axis. The two S-shaped portions enclose a generally heart-shaped interior region 130.
The fastener device 100 includes an anchor portion 120 coupled to a catch portion 120 by a coupler portion 115. The anchor portion 110 includes two anchor segments 112a-112b. Each anchor segment 112a-112b is connected, at a first end, to the other anchor segment 112a-112b and connected, at a second end, to a coupler segment 117a-117b of the coupler portion 115. The catch portion 120 includes two catch segments 122a-122b. Each catch segment 122a-122b is connected, at a first end, to a coupler segment 117a-117b of the coupler portion 115 and free, at a second end.
As noted above, each anchor segment 112a-112b is connected, at a first end, to the other anchor segment 112a-112b. This connection 114 may define a bridge angle facing away from the interior portion 130. The bridge angle may be less than 180 degrees. In particular, the bridge angle may be acute, right, or obtuse. In one embodiment, the bridge angle is approximately 100-110 degrees.
As also noted above, each anchor segment 112a-112b is connected, at a second end, to a coupler segment 117a-117b of the coupler portion 115. Each of these connections 116a-116b may define an anchor angle facing towards the interior portion 130. The anchor angle may be less than 90 degrees. In one embodiment, the anchor angle is approximately 40-50 degrees.
As noted above, each catch segment 122a-122b is connected, at a first end, to a coupler segment 117a-117b of the coupler portion 115. Each of these connections 126a-126b may define a catch angle facing away from the interior portion 130. The catch angle may be less than 90 degrees. In one embodiment, the catch angle is approximately 20-40 degrees.
As also noted above, each catch segment 122a-122b may be free, at a second end. Each catch segment 122a-122b may include a cap 124a-124b at the second end. The cap 124a-124b may be integral with the catch segment 122a-122b and be defined by machining smooth or polishing the second end of the catch segment 122a-122b to reduce abrasion of fabric near the cap 124a-124b. Alternatively, the cap 124a-124b may be a separate piece that is installed upon the second end of the catch segment 122a-122b. For example, the cap 124a-124a may be a coating of thermoset plastic or polypropylene. In one embodiment, the entire fastener device 100 is coated in a thermoset plastic or other material.
The coupler portion 115 includes two coupler segments 117a-117b. Each of the coupler segments 117a-117b is connected, at a first end, to an anchor segment 112a-112b at an anchor-coupler connection 116a-116b and connected, at a second end, to a catch segment 122a- 122b at a catch-coupler connection 126a-126b. The catch-coupler connections 126a-126b may define a coupler-coupler connection 119 having a coupler angle facing towards the interior portion 130. The coupler angler may be less than 90 degrees. In one embodiment, the coupler angle is approximately 50-70 degrees. In one embodiment, the coupler segments 117a-117b do not touch. Thus, the interior region 130 may not be completely bounded by the fastener device 100.
In one embodiment, the catch segments 122a-122b may be generally parallel to the anchor segments 112a-112b. In one embodiment, the catch angles may be approximately equal to the angles. In one embodiment, the sum of the coupler angle and both catch angles may be less than 180 degrees.
The fastener device 100 may be any size and may have many different proportions based on the lengths of the segments and the various defined angles. In one embodiment, the fastener device is approximately 5 cm by 5 cm. For example, the distance between the caps 126a-126b may be approximately 5 cm. The length of the cap segments 122a-122b (e.g., the distance between the cap 124a-124b and the catch coupler connection 126a-126b) may be approximately 2.5 cm. The length of the coupler segments 117a-117b (e.g., the distance between the anchor-coupler connection 116a-116b and the catch-coupler connection 126a-126b) may be approximately 5 cm. As noted above, this length may be any value. For example, the length of the coupler segments 117a-117b may be between 2.5 cm and 7.5 cm. The length of the anchor segments 112a-112b (e.g., the distance between the anchor coupler connection and the anchor connection 114) may be approximately 1.5 cm.
The width of the anchor portion 110, as defined by the length of the anchor segments 112a-112b and the anchor angle, prevents rotation of the fastener device 100. Thus, the fastener device 100 remains flush with the first piece of fabric 210 once installed. This may reduce the chance of the fastener device 100 catching on foreign objects.
A force pulling apart the first piece of fabric 210 and second piece of fabric 220 is spread by the fastener to a number of contact points. At the anchor portion 110, the force is spread to where the fastener device 100 passes through the anchor apertures 212a-212b. Further, portions of the first piece of fabric 210 may be evenly forced towards each anchor aperture 212a-212b, potentially preventing the fastening device 100 from moving out of alignment.
At the catch portion 120, the force is spread to the catch-coupler connections 126a-126b. Further, such a force is unlikely to bend the catch segments (e.g., increase the catch angle) because of the small moment arm between the catch-coupler connections 126a-126b and the point of contact with the second piece of fabric 220.
The coupler segments 117a-117b may be any length. In one embodiment, the coupler segments 117a-117b are of a shorter length such that the second piece of fabric 220 covers all of the coupler segments 117a-117b and may cover the anchor apertures, minimizing the appearance of the fastener device 100. In another embodiment, the coupler segments 117a-117b are of a longer length such that the coupler segments 117a-117b are at least partially exposed, making the fastener device 100 also act as an extender such as may be used for the waistband of pants or shorts. For example, the coupler segments 117a-117b may have a length of approximately twice a length of the catch segments 122a-122b. As another example, the coupler segments 117a-117b may have a length of at least five times a length of the catch segments 122a-122b.
The method 300 begins, at block 310, with the provision of a workpiece. The workpiece may be a length of solid cylindrical metal wire approximately 20 cm in length.
At block 320, the workpiece is bent at a first location to define an anchor connection, such as the anchor connection 114 of
At block 330, the workpiece is bent at two second locations to define anchor-coupler connections, such as the anchor-coupler connections 116a-116b of
At block 340, the workpiece is bent at two third locations to define catch-couple connections, such as the catch-coupler connections 126a-126b of
The bending operations of block 320-340 may be performed in any order. For example, in one embodiment, the third bending operation of block 340 may be performed before the second bending operation of block 330.
At block 350, the workpiece is finished. The finishing may include placing caps of the free ends of the catch segments. For example, the free ends of the catch segments may be coated in plastic or another material. The finishing may include machining smooth or polishing the free ends of the catch segments to prevent abrasion of other materials. The finishing may include coating the entire workpiece in plastic or another material. The finishing operation of block 350 may be performed, in whole or in part, before or between the bending operations of blocks 320-340. For example, the free ends of the catch segments (e.g., the free ends of the workpiece) may be polished before the bending operations of block 320-340.
At block 410, the fastener device is inserted into a first piece of fabric. In one embodiment, the fastener device may be installed by threading the fastening device sequentially through two anchor apertures of the first piece of fabric. The two anchor apertures may be formed by an awl or other sharp instrument. Once installed, as shown in
At block 420, the fastener device (or a portion thereof) is inserted into an aperture of a second piece of fabric. In one embodiment, a catch portion of the fastener device may be inserted into the aperture. For example, the catch portion may include two catch segments and the free end of each catch segment may be sequentially inserted into the aperture.
