DETAILED DESCRIPTION
[0021]
[0022] The example kit may include clips of different shapes. In one example embodiment, the kit may include either, or both a C-shaped clip 26 or an S-shaped clip 28. Either of the C-shaped clip 26 and the S-shaped clip 28 provide for securement of ends of links formed from the elastic bands 22.
[0023] Referring to
[0024] Each link 38 is formed by folding an elastic band 40A-C on to itself to define end portions 42A-C that are captured by a corresponding mid-portion 44A-C of another of the elastic bands 40A-B. The end portions 42A-C are not terminal ends as a closed loop structure does not include ends. Accordingly, the term end as it relates to the end portions 42A-C and as used in this disclosure, are the sections of an elastic band that are captured by another elastic band as show in
[0025] The disclosed loom 24 supports the elastic bands in a defined relative orientation to enable many different linking variations based on the simplified Brunnian link shown in
[0026] Referring to
[0027] Referring to
[0028] Each of the first connector portions 68 defines a pocket and each of the second connector portions 70 defines a tab. The tab is received within the pocket at each connection indicated at 65. Each connection is a light interference fit between the first connector portion 68 and the second connector portion 70 to provide a firm sturdy fit. Although two bases 32A and 32B are shown attached to each other to increase the overall width, additional bases may be similarly connected to further increase the width. Notably, the increase in width provides a doubling of the number of columns 54 of openings 52.
[0029] Referring to
[0030] Although a specific configuration of the connector portions 68, 70 is shown by way of example, other connector structures that provide for the attachment and securement of multiple bases may also be used and are within the contemplation and scope of this disclosure. Moreover, although two bases 32A, 32B are shown attached lengthwise, additional bases may be added to further increase the length of each column.
[0031] Referring to
[0032] Each of the plurality of pins 34 includes a key end 106 disposed on an end distal from a top end 98. An outwardly extending top flange 96 is disposed at the top end 98. An intermediate flange 102 is disposed between the top flange 96 and the bottom portion 100.
[0033] An upper body portion 112 is disposed between the intermediate flange 102 and the top flange 96. A lower body portion 114 is disposed between the intermediate flange 102 and the bottom portion 100. In one example embodiment, the upper body portion 112 and the lower body portion 114 are of a common width 118. The body portions 112, 114 are generally cylindrical, but are interrupted by a slot 104. Accordingly, a cross-section of the body portions 112, 114 is not a complete circumference due to the slot 104.
[0034] The top flange 96 includes a width 120 that is larger than the width 118. The larger width 120 of the top flange 96 provides for maintaining elastic bands on the pin 34 when forming links. Accordingly, the top flange 96 extends outwardly relative to the upper and lower body portions 112, 114.
[0035] The slot 104 extends from the bottom portion 100 to the top end 98 and extends through the top flange 96. The example slot 104 does not extend through the bottom portion 100. The slot 104 provides a space within the pin 34 into which a hook tool may extend to grasp an elastic band supported on the pin body 112. The slot 104 further provides for an elastic band to be grasped and pulled through the slot 104 and inside of another elastic band supported on the upper body portion 112 during the creation of a link.
[0036] In one example embodiment, the bottom portion 100 includes a front side 105 that is a partial squared off shape that extends outward from the generally circular periphery of the bottom portion 100. The slot 104 and the front side 105 are aligned in the example pin 34. A forward rib 122 is disposed on each side of the slot 104 and extends to the front side 105 of the bottom portion 100. The forward ribs 122 provide rigidity to the pin 34 to accommodate forces introduced by elastic bands stretched across pins 34.
[0037] The pins 34 have a generally U-shaped cross-section when viewed from the top down as shown in
[0038] Each of the pins 34 include the key end 106 that are of a common configuration for all of the plurality of pins 34. The key end 106 provides an interference fit with openings 52 of the base 32 to securely hold the pins 34 in a desired location and orientation. The disclosed key end 106 is generally X shaped with a first wall 108 arranged transverse to a second wall 110. The walls 108 and 110 cross each other at the center of the key portion 106. The walls 108, 110 extend away from the bottom portion 100 a distance 123. An intersection of the first wall 108 and the second wall 110 is generally disposed along the pin axis 116.
[0039] The first wall 108 and the second wall 110 are symmetric in that both walls 108 and 110 have a common length 122 and width 124 (best shown in
[0040] Referring to
[0041] Each of the large notches 74 include side surfaces 78. Each of the small notches 76 include side surfaces 80. The side surfaces 78, 80 engage corresponding ones of the first wall 108 and the second wall 110 of the key end 106 to secure the pin 34 in place. In the disclosed example, the notch configuration provides for the pin 34 to be rotationally orientated in 45 degree increments.
[0042] Referring to
[0043] As indicated at increment A, the first wall 108 is engaged at opposing contact points 130 and 132 to side surfaces 80 of opposing small notches 76. The second wall 110 is engaged at opposing contact points 126 and 128 to side surfaces 78 of the opposing large notches 74. Each of the contact points 126, 128, 130 and 132 are an interference fit to prevent the pin 34 from coming free of the opening. The opposing sets of contact points balances forces to hold the pin 34 firmly in place.
[0044] The fit indicated at increment B shows the key end 106 rotated one increment 134 as shown by the placement of the wall portion corresponding with the numeral 1. In this example embodiment, the rotational increment 134 is 45 degrees. The contact points 126 and 128 of the second wall 110 move from the large notches 74 to small notches and contact corresponding side surfaces 78. The first wall 108 is fit within the large notches 74 and against opposing side surfaces 80. Accordingly, in this incremented position, each of the first wall 108 and the second wall 110 is held in place by opposing contact points.
[0045] The fit indicated at increment C is further incremented by 45 degrees about the pin axis 116. The opposing contact points 126 and 128 switch sides of each wall 108 and 110 of the key end 106. The second end wall 110 moves into different ones of the small notches 76. The first end wall 108 moves to another side of the large notches 74.
[0046] The fit indicated at increment D is rotated another 45 degrees. The first wall 108 is moved from the large notches 74 into a small notch 76 and the second wall 110 is moves into a large notch 76. The contact points 126, 128, 130 and 132 are on opposite sides of each of the corresponding walls 108 and 110.
[0047] The fit at increment E is rotated 180 degrees from the first increment A. In this position, the first wall 108 is disposed within small notches 76 and the second wall 110 is disposed within the large notch 74. The contact points are reversed but remain on opposing sides of each corresponding wall 108, 110.
[0048] The fit at increment F is rotated another 45 degrees with the first wall 108 moving into the large notches 74 and the second wall 110 moving into small notches 76.
[0049] The fit at increment G is rotated another 45 degrees such that the forward face of the pin 34 indicated by the arrow has now been incremented 270 degrees from the starting point indicated at increment A. In the incremented position G, the first wall 108 is disposed against side surfaces 80 of the large notches 74 and the second wall 110 is incremented into another small notch 76.
[0050] The fit at increment H moves the second wall 110 back into the large notches 74 and the first wall 108 into the small notches 76. The forward face of the pin indicated by the arrow is now incremented 315 degrees from the initial incremented position A. In this position, the second wall 110 is disposed on a side wall 78 of the large notch 74 that is opposite that of the second wall in the increment position A. The first wall 108 is disposed in the small notches 76.
[0051] A further incremental rotation of the pin 34 will place the front face indicated by the arrow back at the location shown at increment A.
[0052] Accordingly, the example pins 34 may be set at a desired rotational position about the pin axis. In the disclosed example, the pin 34 may set at rotational orientation in 45 degree increments to set the forward face of the pin 34 in a direction that corresponds with a desired linked structure. Although the example opening 52 provides for rotationally setting of each pin in 45 degree increments, other increment graduations could be used, such as for example, 30 degrees, 60 degrees and/or 90 degrees and are within the contemplation and scope of this disclosure.
[0053] Referring to
[0054] Referring to
[0055] The example loom 24 provides for the assembly and removal of elastic bands in different directions as defined by the orientation of each pin 34. As is shown in
[0056] A second group of pins 140 are angled relative to the longitudinal length of the base 32 and face in a second direction that is different than the forward facing direction toward the front end 56. A third group of pins is indicated at 142 and face in still another direction that is different than the direction of each of the first group 138 and the second group 140. In one example embodiment, the second group 140 faces in a direction 144 that is 45 degrees from the forward facing first group 138, and the longitudinal length of the base 32. The third group 142 faces in a third direction 146 that is 90 degrees from a line 148 that is parallel to the longitudinal length of the base 32. Accordingly, the pins 34 in the example loom 24 includes at three pins 34 that may all be arranged to face in different directions.
[0057] In one operational example embodiment, at least three pins 34 are inserted into openings 52 within the base 32 individually and separately as part of predefined pattern with desired rotational orientation. The rotational orientation of the at least three pins 34 is selected relative to the forward facing direction indicated by arrow 136 and the desired pattern. The forward facing direction 136 is parallel to the longitudinal length of the base 32 and toward the front end 56. At least one of the pins 34 is positioned at an angle different than at least on other of the example pins 34. In one example embodiment, at least one of the pins 34 faces away from another of the plurality of pins 34 as is shown by the pairing of pins indicated at 150.
[0058] In the disclosed example shown in
[0059] Accordingly, the example kit 20 and loom 24 provides for the formation of many variations of linked structures with individually installable and rotationally orientated pins 34.
[0060] Although an example embodiment has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this disclosure. For that reason, the following claims should be studied to determine the scope and content of this disclosure.
