Description

DEVICE PE SWBCtQW FIELD OF THE INVENTION The present invention relates to fasteners in general and more particularly to fasteners that are used to pull and hold two joined members.

There are a number of commercially available fasteners that are operated to pull and hold together two members, for example two panels. The panels can be portable enclosures, packaging containers, instrument containers, transit containers, folding tables, suitcases and other packages, to name a few. In general, these fasteners consist of two separate elements, each of which is connected to one of the panels. For example, one panel may be a container lid and the other panel may be the body of the container. These fasteners can be used to obtain an airtight seal and can be used to compress a package placed between the two panels. Examples of these fasteners are described in U.S. Pat. Nos. 2,820,995, 2,853,751, 2,853,752, 4,090,727 and 4,746,151, each incorporated herein by reference. A particular problem seen with fasteners of the prior art is that many are large in configuration, severely limiting the types of applications in which these fasteners can be employed. For example, these Fasteners are not suitable for use in applications where there is only a limited area in which the fastener can be mounted. In addition, many of these fasteners are often considered too "industrial-looking" for use in applications where the appearance of the fastener is an important consideration. For example, such a fastener is illustrated in U.S. Pat. No. 2,820,995 issued to Earnest Schleuter, which discloses a spring loaded link lock fastener 5, comprising a bolt member or bolt 36 mounted on a spring member 31, which in turn is mounted on a clamp 16 secured to a first panel 10. A sliding plate member 42 is received within the latch member 36, which is extended or removed by rotation of a bolt 60, so as to engage a fastener 48 fastened to a second panel 12, to lock the panels together The spring member 31 in addition to holding the latch member 36 to the bracket 16, also provides additional yield strength, which operates to hold the panels in the locked position.Another problem observed in the fasteners of the previous single is that the amount of extension or "holding range" of the fastener is limited, For example, in U.S. Patent No. 2,820,995, the latch member 36 is adapted to extend a specific amount per rotation. of the bolt 60, for coupling the fastener 48. Similarly, in US Pat. No. 4,090,727 granted to Kieran Busch and Cuyler Hoen, and reassigned to the assignee of the present invention, a bolt member or slide member 40 is provided, which is "extended by a specific amount through rotation of three interlocking disc members 50, 55 and 61, for coupling a latch 10. However, in many applications, the amount of extension or "grip range" that is provided by the sliding or latching member is not sufficient. For example, an example is in applications where you want to use thicker gaskets, which will place the sear beyond the "holding range" of the bolt. Still another problem identified in the prior art relates to the mechanical strength of the device. For example, in the patent of the U.S.A. No. 4,090,727, as noted above, the sliding member 40 during operation travels through rotation of the three disk members 50, 55 and 61. In this configuration, the disk member 50 is placed seated or supported within a opening 37 of the handle member 31, and connects to the two remaining disc members 55, 61 by a rivet 70. In addition, each of the disc members 50 and 55 are provided with an enhancement extending from their upper surfaces and projecting to an opening corresponding to disk members 55 and 61, respectively, for positioning the disk members relative to one another. In operation, the three disc members are rotatable relative to the rivet 70 in order to extend or remove the sliding member 40.

A disadvantage is that the disc member 50 can be peeled from its seated position within the opening 37 of the member Se cuff 31, reducing the total resistance of the bolt and possibly leading to damage of the various components or complete failure of the device. In addition, another disadvantage is that the rotation of the disk members in order to operate the bolt may be more difficult due to increased frictional resistance. Another disadvantage is that the lower disk member 50 and the middle disk member 55 can separate and release the connection between the corresponding enhancement and opening between the disk members, also resulting in bolt failure. In general, these problems in bolt operation can occur due to excessive loads that are exerted on the device, for example what may occur during operation of the device as the disk members are rotated or when under load or by contact directly on the bolt. same. The present invention has been developed in view of the above and to overcome the deficiencies of the prior art. SUMMARY OF THE INVENTION The present invention provides a fastener adapted to be fastened on a first member, for fastening a fastener attached to a second member.

Now with reference to the drawings in detail, where like reference numerals indicate like elements throughout the various views, a perspective view of a fastener according to one embodiment of the present invention is illustrated in FIG. The fastener 10 as illustrated includes as its portions, a base member 12, a sleeve member 14, a sliding member 16, cam means 18, a cam member 20 and turning means 22. The fastener portions 10 will be described in more detail in the following paragraphs.

As illustrated in Figure 1, the fastener 10 is adapted to be connected to a first member 100. As previously indicated, the first member may comprise a panel, closure or the like, such as a body portion of a container. The connection of the fastener 10 to the first member 100 is achieved by the base member 12. The base member 12 is connected to the first panel 100 by screws or another convenient fastener such as an adhesive. As best seen in the exploded view of Figure 2, in the present embodiment, the base member 12 includes a bottom plate having through holes 24 for connecting to the first panel 100 by a pair of screws (not shown). The base member 12 may also have opposite side portions 26 and 28 on respective opposite sides of the bottom portion of the base member 12. Each of the side portions 26 and 28 have through holes respectively 30 and 32, through which it is fastened an elongate pin 34. The pin 34 in the present embodiment has a head at one of its ends, placed on the outside of a side portion 26, and a hammered portion, placed on the outside of the opposite side portion 28. The sleeve 14 has as its integral portions, an upper surface 38, a lower surface 40, a central portion 42 and a connecting portion which in the present embodiment, comprises a bent elongate tubular portion 44. The rod of the pin 34 fits within the portion tubular 44 so that the sleeve member 14 is hinge and is rotatable relative to the pin 34. The hinge means comprise the pin 34, and the tubular portion 44 allows pivotable movement of the sleeve member 14 relative to the base member 12. As best illustrated in the front view of the Figure 3, the sleeve member 14 also includes a sleeve, which in this embodiment is constituted by two lateral flanges turned to the side, forming sleeve portions 46 and 48 on their opposite sides, the internal faces of which form a guide. As illustrated in Figure 2, the sleeve member 14, at its central portion 42, includes a central circular through hole 50, which in the present embodiment centers on a raised raised portion 52, and has an imaginary center. The sleeve member 14 may also include a channel 53 in its lower surface 40 extending from the opening 50 to its front end as best seen in Figure 3. The sliding member 16 fits and slides within the two portions of the same. side sleeves 46 and 48 of the sleeve member 14. The sliding member 16 can move longitudinally within the slider formed by the sleeve portions 46 and 48. As illustrated in Figure 2, the sliding member 16 is a generally rectangular member that substantially radiated at one end to form a loop-type lip portion 54. The flat portion of the sliding member 16 has an elongated cam opening 56 through it. A second The generally U-shaped opening 58 can also be provided through the flat portion of the sliding member 16 which forms a flexible resilient tongue 60 having a small raised elevation 62 adjacent its end. The lug 62 runs inside the channel 53 as the sliding member 16 moves longitudinally within the sleeve member 14. The cam means 18 is received within the opening 50 of the sleeve member 14 for rotatable movement there, the cam member 20 it extends from the cam means 18 and towards the cam opening 56 of the sliding member 16, the details of which will be described more fully below. The turning means 22, in this embodiment, comprises a handle having inwardly projecting and opposing fingers 64 and 66, which are substantially square in cross section and fit within the cam means 18, in the manner described below. , to provide rotation of the cam rofids 18. In accordance with the present invention, the cam means 18 preferably comprises at least one disk member such as the type illustrated in US Pat. Nos. 2,820,995 and 2,853,751 or more preferably two or more disc members such as of the type in U.S. Pat. No. 4,090,727, where a series of three stacked disk members and interconnected, are provided. For purposes of illustration, the present embodiment, the cam means 18 is illustrated in Figure 2 comprising the three disk members 68, 70 and 72. The first disk member 68 as illustrated in FIG.

Figure 4 is round in top view and its diameter preferably is slightly smaller than the diameter of the opening 50 in the sleeve member 14, so as to fit within the opening of the sleeve member 50. The first disc member 68 preferably has a pair of holes 74 and 76 and a small projecting embossment 78. In addition, the first disk member 68 may also include an optional indentation 80 in its opposite side elevation 78 and aligned therewith, as illustrated in dotted lines. in the side view of Figure 5. In this embodiment, the lug 62 on the tab 60 of the sliding member 16 removably engages in the hole 76 as a detent, when the sliding member 16 is removed. As illustrated in Figure 4, the hole 76 has a round shape and extends through the disc member 68, however the hole 76 may also comprise an indentation that does not extend through the disc member 68. Also, the position of the or The opening 76 may vary depending on the position of the elevation 62 of the sliding member 16 or alternatively, the hole 76 may be eliminated where the elevation 62 is not provided or the elevation 62 may be adapted to engage the indentation 80, such that the hole 76 is not required. In addition, the orifice 74 in the present embodiment is substantially round in configuration, however, it will be understood that other shapes of the orifice 74 may also be employed. The second disc member 70 as illustrated in FIG.

Figure 6 is also round in top view and preferably has a slightly larger diameter than the diameter of the first disc member 68. In this embodiment, the second disc member 70 runs over the enhancement 52 of the sleeve member 14 and not within of the opening 50. The second disk member 70 has a hole 82 that is of the same configuration as the hole 74 in the present embodiment, however this is not required. The second disk member 70 is also included within a small raised elevation 84 and a small indentation 86 after the elevation 84, as illustrated in dotted lines in the side view of Figure 7. The elevation 78 of the first disk member 68 It fits inside the indentation 86 of the second disk member 70. Alternatively, the small indentation 86 may also comprise an orifice extending completely through the second disk member 70. The second disk member 70 as illustrated in Figure 6 it also includes opposite lateral indentations 88 and 90 in which the fingers 64 and 66 of the turning means 22 are received. The third disc member 72 as illustrated in Figure 8 is preferably a sufficiently flexible material. such as spring metal, for example metal in spring steel plate and includes a hole 92 which in the present embodiment is "same diameter as holes 74 and 82 however, this is not required." The third disc member 72 also includes a smaller orifice 94 or alternatively an indentation in which the embossment 84 of the second disk member 70 fits. Furthermore, preferably, the third disk member 72 bends slightly about its central axis between the holes 92 and 94. as best seen in the side view of Figure 9. The third disc member 72 holds the turning means 22 in position and "spring pressure" in the substantially square fingers 64 and 66, to tend to restore the means of rotation. Turn either to a flat or elevated position. The interlock of the three disc members 68, 70 and 72, so that they can rotate together as a unit, is achieved by the lugs 78 and 84 that fit into the indentation 86 and hole 94, respectively, as illustrated in FIG. the sectional view of Figure 10 that is taken on line 10-? of Figure 1. The cam member 20, as illustrated in Figure 2 in the present embodiment, comprises a rivet having a head 98 and a generally elongated rod 104. As best seen in Figure 10, the head of enlarged rivet 98 is sufficiently large such that its diameter is greater than the width of the elongated cam opening 56 of the member slider 16, which prevents the rivet from being pulled through the opening 56. The rod 104 of the rivet projects through the opening 56 and also projects through the aligned holes 74, 82 and 92 through the three members of disk. The upper part of the rivet opposite the head 98 is hammered and forms an enlarged head over the hole 92, in the third disc member to hold the three disc members 68, 70 and 72 attached. When the turning means 22 is rotated, the cam member 20 will move within the cam opening 56 of the sliding member 16 and rotate relative to the imaginary center of the opening 50 of the sleeve member 14, which will extend or withdraw the member. 16 a predetermined amount, as will be described in detail below. As will be understood, the cam member according to the present invention can also be attached to the first disk member without also extending through it, where for example, the cam member is not required for connection of the disk members. or when only one disk member comprises the means of 1 «va. The portions of the fastener 10 described above can be manufactured by conventional techniques and from commercially available materials, such as die-cutting from sheet metal. In accordance with the present invention, means are provided to increase the predetermined amount of extension or removal of the sliding member 16. In the present embodiment, the means of increase are provided through the interaction of the first disk member 68 and the cam member 20. Specifically, the hole 74 through the first disk member 68 is it places closer to the perimeter than to the center of the first disk member 68, which in turn also places the rod 104 of the cam member 20 closer to the perimeter of the first disk member 68 than its center. The operation of which will be described in the following paragraph. In operation, starting with the sliding member 16 in its extended position, the sleeve member 14 is rotated with respect to the hinge means, so that the hook-like lip portion 54 of the sliding member 16 enters into engagement with a detent 102. , which is attached to a second member 103, for example the second member 103 may be a portion of a lid of a container. As illustrated in Figure 11, fastener 102 comprises a fastener plate portion that is fastened to the second member 103 by convenient fastening means and a bent and curved hook-type J-ibio fastener portion. In this embodiment, the flat detent plate portion is provided with two through holes for securing the second member 103 by screws or other fastening means. The fastener 102 may also comprise an extrusion or other shaped fastener. After the sliding member 16 engages the catch 102, the turning means 22 is turned in the clockwise direction of the hands. watch, if you see directly on the bolt. The cam member 20 is also rotated clockwise with respect to the imaginary center of the three disk members, with the disk members aligned so that their centers meet in a common imaginary line. The rivet rod 104 of the cam member 20 pushes the cam opening 56 and leverages the removal of the sliding cam member 16 within the guides of the sleeve portions 46 and 48 of the sleeve member 14. At the end of the turning movement , the sliding member 16 is completely removed in the position illustrated in Figure 10 and the elevation 62 of the sliding member 16 moves within the indentation 78 of the first disc member 68. Because the position of the rivet rod 104 is closer to the perimeter than to the center of the first disk member 68, the travel distance of the sliding member 16 within the guides of the sleeve portions 46 and 48 increases as the sliding member 16 is moved by the cam member 20 to the full withdrawal position from its extended position. In the complete removal position, the hook-like end portion of the fastener 102 is secured with the hook-like lip portion 54 of the sliding member 16. To unfasten the fastener 10, the operation is reversed, specifically, the turning means 22 is rotate in the counterclockwise direction, thereby causing the rivet rod 104 of the cam member 20 rotate and thus pry the sliding member 16 to its extended position and also rotate the indentation 78 away from the elevation 62. Similar to the above-noted acerbing process, due to the position of the rivet stem 104 that is closer to the perimeter than the center of the first disk member 68, there is an increase in the travel distance of the sliding member 16 within the sleeve portions 46 and 48, as the sliding member 16 is moved by the cam member 20 to its extended position from its position completely removed. Another example of cam means with multiple disc member in relation to clip 10 is illustrated in Figure 12. In this embodiment, cam means 18 is illustrated comprising the three disc members 68A, 70A and 72A. The first disk member 68A is illustrated to correspond in configuration to the disk member 68 set forth above and will not be described further here for this reason. The second disk member 70A as illustrated in FIG. 13, preferably is of a sufficiently flexible material, such as sheet metal for spring steel, and includes a slot 82A through which, in this embodiment it radiates substantially in configuration. The slot 82A in operation corresponds to the hole 82 of the disc member 70 described above for receiving the cam member. The second disk member 70A also includes a second slot 86A which is substantially radiated in configuration in this embodiment. The slot 86A corresponds to the indentation 86 of the disk member 70 in its operation to receive the enhancement extending from the first disk member. The second disk member 70A preferably also includes a round shaped hole 84A and a pair of opposed side extensions 88A and 90A substantially square in shape. Further, preferably the second disk member 70A is bent slightly about its central axis which bisects the slots 82A and 86A as illustrated in the side view of Figure 14. The third disk member 72A as illustrated in Figure 12, it is round in top view and includes a through hole 92A which is round in shape in this embodiment and which corresponds to the hole 92 of the disc member 72 described above for receiving the cam member. The disc member 72A also includes a downwardly extending flange 43A on its perimeter, which includes a pair of opposing side indentations 88B and 90B (only 90B is visible in the Figure) -) which are substantially square in shape in this embodiment, the substantially square fingers of the rotation means and side extensions 88A and 90A of the second disk member 70A fit within the sual. The lateral indentations 88B and 90B of the third disc member 72A keep the turning means in position and the lateral extensions 88A and 90A of the second disc member 70A exert spring pressure on the discs. substantially square fingers to tend to restore the turning means either to a flat or elevated position. The third disk member 72A is also included with a first raised elevation 94A, extending from its lower surface that fits within the hole 84A of the second disk member 70A, as illustrated in the bottom and side views of Figures 15 and 16. The interlock of the three disk members 68A, 70A and 72A, such that they rotate together as a unit, is achieved by the 78A enhancement of the first disk member 68A and the 94A of the third disk member 72A that it fits in the slot 86A and hole 84A of the second disk member 70A, respectively. The remaining operation of the three disc members 68A, 70A and 72A corresponds to that described above with respect to the disc members 68, 70 and 72. Another aspect of the present invention is to provide means for retaining a cam mechanism within the opening of a sleeve member as the cam is rotated. In order to illustrate this feature of the present invention, reference is made to Figure 17, which illustrates an exploded perspective view of a fastener 110 incorporating a cam means mode according to the present invention. For reasons of clarity, the portions of the fastener 110 corresponding to the portions described in relation to the fastener 10 will be described using the same numerical designations starting with 100. Similar to what has been described above in relation to the fastener 10, the camming means according to this aspect of the present invention, preferably comprise at least one disk member and more preferably two or more disk members such as the types illustrated in Figures 2 and 12. As illustrated in Figure 17, for purposes of this illustration, the cam means 118 comprises the three disc members 168, 170 and 172, which are similar to the disc members. 68, 70 and 72 described in relation to the fastener 10. The differences in the disc members 168, 170 and 172 * Is in the configuration of the first disk member 168 and the positions of the holes 174, 182 and 192 that receive the cam member 120. Specifically, in this embodiment the first disk member 168 is provided having means for coupling the bottom surface 140 of the sleeve member 114 proximate the opening 150 of the sleeve member 114 when the disc member 168 is mounted. As illustrated in Figure 17, the coupling means in this embodiment comprise a flange 175 fv-e extends radially outwardly from the perimeter of the first disk member 168 adjacent its lower disk surface. Preferably, the flange 175 extends by a predetermined amount around the perimeter of the first disk member 168 and in the present embodiment, the flange 175 as illustrated in the top plan view of Figure 18, extends completely around the perimeter Of the first disc member 168. The flange 175 defines an increased diameter area of the first disc member 168, which operates to stop the cam means 118 within the opening 150 of the sleeve member 114 through its engagement with the inner edge of the sleeve member. the cam opening 150 and the lower sleeve surface 140. Specifically, as illustrated in the sectional view of Figure 19, which is taken on the same line illustrated in Figure 10, an upper surface 177 of the flange 175 is placed adjacent, although not necessarily in engagement with the lower surface 140 of the member of 'sleeve 114, when the cam means 118 is mounted. In this embodiment, as illustrated in Figure 17, assembly is achieved by inserting the first disc member 168 to the bottom of the sleeve member 114 and through the opening 150 from the direction of the bottom surface 140 to the top surface 138. Similar to that described above in relation to the fastener 10The three disk members 168, 170 and 172 are interconnected by the cam member 120 extending through the aligned holes 174, 182 and 192 extending through the disk members. As illustrated in Figure 18, the position of the hole 174 for the first disc member 168 is closer to the perimeter than to the center of the disc member 168, however it will be understood that this is not required. position of the hole 174 through the first disc member 168 can be provided anywhere: for example, in any position extending from the center to the perimeter read disk member 168. Similarly, the same will apply with respect to the remaining disk members 170 and 172 that are placed to align with the disk member. hole 174, which extends through the first disk member 168. Furthermore, as previously indicated in relation to the first disk member 68, the position of the hole 176 can alternatively be varied or eliminated on the first disk member 168. In operation, the upper surface 177 of the flange 175 is adapted to couple the lower surface 140 of the sleeve member 114 which maintains the position of the cam means 118 and also acts as a support surface. As previously indicated, in prior art devices, the first disk member can be detached from its position within the sliding member when the bolt is under load. In general, in the devices of the prior art, the detachment of the first disk member is found to be more likely at the opposite end of the cam member location In the present invention, the coupling between the flange 175 and the lower surface 140 of the sliding member 114 will prevent detachment of the first disc member 168, in situations where detachment would have occurred in prior art devices.

The remaining portions and operation of the fastener 110 are the same as those already described in connection with the fastener 10, and for reasons of brevity will not be described in connection with the present embodiment. In Figures 20 and 21 there is illustrated a second embodiment of a first disc member in relation to the fastener 110. In this embodiment, the first disc member 268 is provided with a single tab 275 that extends only partially around the perimeter of the first disc member 268 and positioned generally opposite hole 274. As illustrated, tongue 275 extends approximately 45 degrees around the perimeter, however, it will be understood that tongue 275 may extend roughly about the perimeter of the perimeter of the perimeter. In addition, in the present embodiment, the position of the tongue 275 is generally opposite the hole 274, since previously the detachment of the first disc member in devices of the prior art is indicated. likely to occur at the position of the disc / 2"opposite the cam member, however it will be understood that the tongue 275 can provide be in other places on the perimeter of the first disk member 268 where desired. Further, in the present embodiment, the tongue 275 is generally illustrated radial in shape, however this is not required and the tongue 275 may also be provided with other configurations equally.

In Figures 22 and 23 there is still illustrated another embodiment of a first disc member in relation to the fastener 110. In this mode, two tabs 375 and 376 are provided extending from the perimeter of the first disc member 368, generally opposite the orifice 374. As illustrated, the tabs are generally spaced 45 degrees apart and are substantially square in configuration. In the present embodiment, while two tabs 375 and 376 are illustrated, it will be understood that any number of tabs may be provided for the same purpose, for example 1, 2, 3, etc. Also, the tabs may be of any size or particular configuration and placed at any desired location or spacing from each other on the perimeter of the disk member. For example, three tabs may be provided with the first and third tabs spaced approximately 180 degrees from each other and the second tab generally positioned between the first and third tabs and opposite the cam member. In addition, the first and third tongue members can be considered similar to the spouts 375, 376 and the second tongue member can be configured corresponding to the tongue 275. It will be understood that this example will be for illustration purposes only and in no way limits the number of possible variations. The assembly of the first disk members 268 and 368 described above can be accomplished in the same way as the first disk member 168, which is upwardly from the bottom of the sleeve member or alternatively downwardly within the sleeve member when possible, depending on the particular configuration of the tongue portions. As previously indicated, another aspect of the present invention is to provide a cam mechanism of increased strength and durability. Specifically, in prior art devices where more than one disc member is provided, such as in U.S. Patent No. 4,090,727, the disc members can be separated and disconnected with each other when the bolt is under load, possibly leading to device failure. For purposes of illustration, the present feature will be described in relation to the fastener 10. With reference to Figure 2, according to one embodiment, cam means 418 is provided by the combination of the third disk member 72 with a disk member. 468, which is in place of the disk members 68 and 70. Advantageously, the disk member 468 is of one piece under construction, which overcomes the problem of the prior art wherein multiple disk members will be separated and The specific configuration of the disk member 468 is best seen in Figures 24-26 In this embodiment, the first disk member 468 defines a lower disk 469 and an upper disk 471 that are integrally connected to each other.

The lower disc 469 as illustrated in Figure 24, is substantially round in the bottom view, and includes a hole 474 for receiving the cam member and an indentation 476. As illustrated in Figures 24 and 26, the hole 474 is substantially round in configuration, however other shapes may also be provided. The indentation 476 is illustrated, a hole extending completely through the lower disc 469 may alternatively be removed or alternatively removed. In this embodiment, the realization in the tongue of the sliding member removably adjusts the indentation 476 as a retainer when the sliding member is removed. The upper disc 471 as illustrated in Figure 26 is round in top view and in this embodiment, its diameter is larger than the diameter of the lower disc 469. The upper disc 471 also includes a substantially round cavity 489 through its midsection , which extends to the lower disc 469. In this embodiment, the upper disc 471 also includes the support member 490 within its cavity 489 and aspirates < J lower level 471 to reinforce the connection between them. The lower disc 469 is illustrated in Figure 24, but also includes indentations 492, generally opposed to the position of the soft support members 490, however the indentations 492 can be removed as desired. The superior disso 471 is also included with a pair of opposite lateral indentations 488B and 490B, which in this modality are Substantially suadradas in form and resiben the fingers substantially suadrados of the turning means. The member of isso 468 can be manufactured by conventional techniques and from somersially available materials, such as extruded from metal. In this embodiment, the orifice 94 through the disk member 72 is illustrated in Figure 2, is not required and can be eliminated. The mounting of the spacer member 468 in this embodiment is achieved by inserting the lower spacer 469 downwards into the opening of the guide member, until the upper spacing 471 in the form of the upper surface of the sleeve member. The remaining operation is the same as the one that was previously disassembled. The camming means 418 in accordance with the present invention, may also insorporate one or both of the sarasteristisas previously disclosed; is to provide means for increasing the predetermined amount of extension or removal of the sliding member or means for retaining the camming means from the opening of the sleeve member. Similar to what was previously discussed in relation to the fastener 10, the insulating means can be provided through the interassion of the cam member are the orifice 474 through the lower disc 469; in particular, the position of the hole 474 is proportionally closer to the perimeter of the lower disc 469 than to the center of the inferior disc 469. In addition, the means ofThe retension can be provided through the interassiórt of the disc member 468 are the sleeve member, similar to the item in rejection to the fastener 110. For purposes of illustration only, a disso member 468A is shown in FIGS. Sada one of the previous sarasteristisas. As will be understood, alternate modalities can insorporate any of the two previously dismayed sarasteristisas. The lower disc 469A in this embodiment, includes a single tab 475A, which extends only approximately around the perimeter of the lower disc 469A, and is generally just opposite the orifice 474A. It should be understood, however, that while a single tab 475A is illustrated, one or more tabs of its desired configuration may be provided and solved at its desired location on the perimeter of the lower disk 469A, such as that previously disclosed to the members of the invention. disso 268 and 368. In the present mode, the interastion of the tab 475A, are the superfisie $ -? bottom of the sleeve member operates to retain the cam means 418A, within the opening of the sleeve member. In addition, the interassión of the upper disc 471A, are the sleeve member, provides an additional mesanismo to retain the position of the cam means 418A. Specifically, as illustrated in FIG. 28, the lower surface 473A of the upper disso 471A, is adapted to enter into a chop.

The upper surface of the sonfound sleeve member is rotated by the cam means 418A. In addition, as shown in Figure 29, in the present embodiment, the upper disc 471A, is provided by an indentation 491A adjacent to the tongue 475A, however it will be understood that it can be eliminated when the indentation 491A is desired. As illustrated in Figures 27 and 29, the means of increase in this mode are provided by the lower disk 469A which includes an orifice 474A, soldered more closely to the perimeter than to the lower disk member 469A. In addition, the upper disso Member, which is illustrated by the disso member 72 in Figure 2, is provided with an orifisium 92 that is solid to align to be the orifice 474A, in order to accommodate the resection of the cam member to through sada one of the orifisios 474A and 92, respec- tively. As previously stated, the interassión of the cam member and the lower disc 469A, provides an increased sanctity of tension or removal of the sliding member, and the means of? * »TVa 4i8A are rotated. The remaining features of the dislodging member 468A are the same as those previously discussed are respectable to the disc member 468. Another aspect of the present invention is to provide a sompasto design fastener, such that the fastener can be mounted in smaller areas but that they still provide enough force to aserrojar adesuadamente. Agree it is this embodiment of the present invention, in Figure 30, a side view of a JIO fastener embodiment is illustrated. The fastener 510 is illustrated, includes its portions, a base member 512, a sleeve member 514, a bypass member 515, a sliding member 516, cam means 518, a cam member 520, and turning means 522 In the present embodiment, the stricture and operasion of the sliding member 516 and the turning means 522 are the same that will be disassembled in recession to the fastener 10 and will not be broken down here again for this reason. The cam means 518 and the cam member '520 can comprise any of the cam means 18, 118, 218, 318 or 418 and associated cam members described above, or any assemblies of the prior art that are adapted for this purpose, are disclosed in the prior art patents previously noted in the foregoing of the invention. For purposes of illustration, in the present embodiment, the cam means 518 is responsive to the cam means 218 and will not be disengaged in greater detail by this • »ß *! Ón. The base member 512 is illustrated in the top view of Figure 31, it extends extending from its bottom portion, at least one and preferably two reals 517 and 519. The reals 517 and 519 may also include an end portion. In the form of a substantially annular gansho, this is illustrated in dotted lines in the side view of Figure 31 (only 519 is visible). In the present embodiment, the reals 517 and 519 in general are restangular in shape and are constituted from an upwardly bent section of the base portion of the base member 512. However, the elevations 517 and 519 may be provided with a shape desired, or we are separate members that are set to the background portion of base member 512. In addition, any sanctity of reals for the same purpose can be provided. The base member 512 further includes two grooves of generally elongated insulated shape 530 and 532, which is provided through the opposite side edges 526 and 528, respectively. In the present embodiment, the slots 530 and 532 extend to an insalination down to about 40 ° to the bottom portion of the upper corners to the front end. However, the slots 530 and 532 can be inset at their desired angle; A preferable range is between 30 ° and 50 °. As illustrated in the sessional view of Figure 33 taken on line 33-33 of Figure 30, the member of w ^ -nq ito 514 is pivotally connected by hinge means to the base member 512. Similar to what is described formerly in recession to the fastener 10, the hinge means comprise a pin 534 and tubular portion 544 of the sleeve member 514. Furthermore, the preferensia pin 534 includes a saber 536 at one of its ends and a hammered portion 536A at the opposite end , one solosado out of the porsiones opposite sides 526 and 528 through the slots 530 and 532 of the base member 512. In addition, the pin 534 is housed within the tubular portion 544 for connection of the sleeve member 514. In this embodiment, the tubular portion 544 does not extend The entire length of the sleeve member 514, which is different from the assembly, is related to the tubular portion 44 of the sleeve member 14. Partially, one of the opposite side portions of the sleeve member 514 advances essally close to the tubular portion. 544 which defines the openings in a substantially superscript manner 550. As illustrated in Figure 34, the diverting means 515 in the present embodiment includes a preferensia torsion spring made of metal, such a stainless steel body, although other suitable materials may also be used. . The torsion spring 515 in the present embodiment, preferably two emboiled poles 521 and 523, a shape of generally U 525 shape extending between the recessed poles 521 and 523 and a pair of end sesions * 7 and 529, which they extend from opposite ends of the recessed poles 521 and 523. Although not illustrated, it will be understood that several portions may be provided in the torsion spring 515, such that a different configuration of torsional spring is provided, the number of wound portions varying, sambiando the number of windings in sada porsión devanada, to name a few susantos. The primordial soneiderasión is that the torsional spring 515 suando is assembled, will be soldered substantially within the outer limits of the limb member 512, an example of which is illustrated in the present embodiment. As illustrated in the session view of Figure 35 taken on line 35-35 of Figure 30, the suture pin 534 is mounted knows within the two recessed porsions 521 and 523, and the U-shaped portion 525 is in asopulation are the two reals 517 and 519 that extend upwards from the base portion of the base member 512. As best seen in Figure 33, the two recessed portions 521 and 523 collapse into the openings substantially in shape. suadrada 550 of the sleeve member 514. As illustrated in Figure 35, preferably the opposite end portions 527 and 529 of the torsion spring 515 extend in the direction of the front of the base member 512 and can also be soldered in order to derive the opposite lateral portions 526 and 528 and the base portion of the base member 512. In addition, the end portions 527 and 529 can also be bent slightly at their end ends, as illustrated in the side view of Figure 34a. When the fastener 510 is in a disassembled position, preferably the pin 534 is soldered to the uppermost ends of the grooves 530 and 532 of the upper corners of the base member 512, as illustrated in Figure 30.

In operation, when the fastener 510 is crimped, it is the fastener, the force of the torsion spring 515 is adapted to provide an additional sawing force in order to hold the panels together. As the sliding member 516 is removed and asynchronous is the detent, the preferensia pin 534 moves against the deflection of the torsion spring 515 downstream in the slots 530 and 532, in the direction of the bottom portion of the base member 512. Insolated positions 521 and 523, due to the connection are the pin 534, also move in the same direction of movement of the pin 534. Similarly, the opposite end portions 527 and 529 of the torsion spring 515 move forward, to the edge 569 of the base member 512, soinsidiendo are the movement of the embobinadas porsiones 521 and 523. The U-shaped portion 525 of the torsional spring 515 is held in place by the reals 517 and 519, in order to avoid movement forward of the U-shaped portion 525. In the fully serrated position, preferensia to the pin 534 is glued between the uppermost and lowermost ends of the slots 530 and 532. In general, the positioning of the catch relative to the fastener 510, determines the position of the pin 534 within the grooves 530 and 532, where the fastener 510 is in a fully askewed position. In addition, the sanctity of force that is provided by the fastener 510 may also be decreased or decreased by varying the angle and / or length of the slots 530 and 532 within the base member. 512. The partiscular configuration of the fastener is the same as that previously disengaged in recession to the fastener 102. When the fastener 510 is unscrewed, the previous session is reversed and the pin position 534 is moved by the deviation of the torsion spring 515 to the uppermost ends. of the slots 530 and 532. In general, the operation of the fastener 510 previously disengaged is similar to the operation illustrated in the US patent. No. 2,820,995. However, an advantage of the present design is that the torsion spring 515 is completely sealed within the limits of the base member 512. Specifically, the torsion spring 515 colsees within the base member 512 between two opposite side portions 526 and 528. As shown in FIG. previously invented, fasteners of the type illustrated in the US patent No. 2,820,995 insorporate spring assemblies that extend away from the fastener itself that both instore the size of the fastener as well as affect the overall appearance of the fasteners. On the contrary, in the} In this manner, since the toreional spring 515 is thinned within the outer limits of the base member 512, the overall size or "footprint" of the fastener is reduced, which allows both to mount the fastener in smaller areas, as well as to improve the estétisa of the device. Another advantage is that the sleeve member 514 and the base member 512 are set by the pin 534 which also increases the total resistances of fastener 510. FIGS. 36 to 48 illustrate alternate embodiments of the deflection means 515 dessritos above. The sarasterística somún in sada one of these modalities is that the means of derivation are confined within the limits of the base member. In order to simplify the next break, only those porsions that are different from those illustrated in Figures 30-35 will be dessribired. In Figures 36 and 37 a first alternate embodiment of the drift means of Figure 515 is illustrated. The drift means in this embodiment include a resilient member 615 defining a cantilevered spring, which extends upwardly from the porsión portion. bottom of base member 612. In the present preferred embodiment, resilient member 615 both extends from, and is integral with, the bottom portion of base member 612, however, resilient member 615 can also be provided as an element. separate subject (the bottom portion of the base member 612. When the resilient member 615 is an integral part of the base member 612, an advantage is that there is a reduction in the number of the fastener somponents.In addition, in the present embodiment, preferably resilient member 615 is generally restangular in configuration and is also radial over its entire length.

Resilient 615 can be formed by modern tänniscs such as die cut or molded. In operation, the tubular portion of the sleeve member adapted to enter underwire is the resilient member 615 proximate its terminating end when the fastener is sawn. Preferably, the configuration of the sleeve member includes a tubular portion 644 extending over the entire length of the sleeve member, which is similar to the pattern in relation to the sleeve member 14 of the fastener 10. Although not illustrated, the member base 612 can also be turned 180 ° in opposition to provide an "external" assembly. In this situation, the operation of the bluff will occur in the same way as it was previously disengaged. Figures 38-48 are alternate modalities, the suals illustrate variations of the resilient member 615. In general, Figures 38-48 illustrate various variations of the shape, shape, and number of resilient members that are • stressed in the base member. It will be understood that the following modalities are only an example and in no way limit the various possible variations that are within the alsanse and spirit of the invention. In Figures 38 and 39 a resilient member 615A is illustrated, which has substantially a V shape.

In Figures 40 and 41 a resilient member 615B is illustrated, which is slightly more stressed and longer than the resilient member 615. A pair of resilient members 615C is illustrated in Figures 42 and 43. Advantages of this design are reduced loading sag due to the additional resilient member, and the positioning of two resilient members 615C also works to maintain the sleeve member during operation. Figures 44 and 45 illustrate a pair of generally insilient resilient members 615D, which define a flexible spring-like flexible sheet spring. Specifically, as is best seen in the side view of Figure 45, the resilient members 615D are tilted down from the base portion of the base member approximately to their mid-portion, and then they are inset back down to the direction of the base member. background portion of the base member. In operation, the tubular portion of the sleeve member is adapted to bend the inclined curve up to the resilient members 615D. Additional features of this design are an unloaded load capacity and the double spring arrangement also functions to maintain the sleeve member during operation. In Figures 46-48, the resilient member 615E comprises a spring of flexible sheet surfaced and detached, preferably of sufficient resilient material such as spring material that is retained in the member. base 612, by puffing a groove 613 formed within the bottom portion. Specifically, the end portion 616 of the ol5E member is inserted into the slot 613. The partular shape of the resilient member 615E can also be varied as desired, such as the shape of the survated portions. In operation, the portion of the tubular sleeve is adapted to blow out the survate portion of the resilient member 615E. Another embodiment of the shunt means 515 is illustrated in Figure 49. In Figure 49, the differences of the fastener 710 relative to the fastener 510 illustrated in Figures J0-35 are in the configuration of the shunt means, sleeve member and base member, which will be demineralized. For reasons of brevity, similar portions will not be dessibed and are designated by the same reference numbers illustrated in Figure 30. As illustrated in the exploded view of Figure 49 and the top view of Figure 50, the base member 712 it extends upwards from its bottom portion, at least tr * n and preferably a pair of reals 717 and 719 which, as illustrated, can also be inset back in the direction of the slots 730 and 732 in the base member 712. In this mode, the reals in general are restangular in cross section and are formed from a porous portion located upstream of the base member 712. However, the realms 717 and 719 can also be provided as separate elements are shown to the bottom portion of the base member 712 and its transverse serving session. The means of 715 in the present embodiment are constituted by an elastomeric material which otes as a compression spring. The elastomeric material may include polyurethane, silisone, thermoplastic elastomer, urethane plastis, EDPM rubber or other suitable materials. In the present embodiment, as illustrated in the front view of Figure 51 and the top view of Figure 52, the elastomer drift means 715, in general are restangular in configuration and include a generally radial groove 716 formed at its end. upon its longitudinal axis, which is adapted to abut the tubular portion 744 of the sleeve member 714, as illustrated in Figure 53. Figure 53 is a sessional view similar to that illustrated in Figure 19. In addition, preferably the The upsurface of the elastomeric drift means 715 is illustrated in FIG. 53, is tad down from the radial slot 716 and in the direction of its front efflux, which in turn blows the reals 717 and 719, to prevent movement to the front of the elastomer drift means 715. In addition, the drift means 715 can also be proportional to the sweat minus one real which extends from its lower surface that rests. ibe within a corresponding opening formed in the base portion of the base member 712, which provides an additional retention force to the advancing movement of the elastomer drift means 715. In the present embodiment, as shown in Figure 51, three enhancements 718, for example one generally restangular in transverse section, are provided by extending from the lower surface and arranged in two lines. , are a realse in the middle of the rear end and two reals in each corner of the front end of the elastomer drift means 715, and three corresponding openings 720 are formed in the bottom portion of the base member 712, to hold the three reals as best seen in Figure 50. However, it should be understood that any number of reals having their convenient cross section and soldered anywhere on the bottom surface of the elastomeric derivative means 715 may be provided, which in turn resides within the corresponding openings formed in the background portion of the base member 712. In addition, the means of deriv Elastomer 715 may also include in its upsurface sections essalonadas hasia opposite down 722, adjacent to K-lateral portions that resilient the opposite sleeve portions of the sleeve member, suando turns the sleeve member. The elastomer drift means 715 may also have a semi-sirsular frame 723 at its front end, to allow sufficient spacing for the rossed connection of the base member 712 through the orifice 724.

As previously stated, they are based on the torsion spring-based deflection means, the important aspect of the elastomer drift means is that if they are assembled, they will collapse subetansially within the outer limits of the base member. Therefore, it should be understood that the derivative member 715 may also be of other configurations to those illustrated in the spirit article and alsanse of the present invention. In osion, the elastomer drift means 715 provides spring retention of the swivel sleeve member of the tubular portion 744 is the wavy portion of the elastomer drift means 715. An advantage of the elastomer drift means is that it can obtain sapasidad of transport of twigs insrementada on the designing of primaverae metálisos of the previous tésnisa or the designs of means of metallic drift identified previously. In addition, the material, hardness or shape of the elastomer drift means can be varied, either to increase or decrease the spring rate, if desired. Another embodiment of the shunt means 715 illustrated in Figure 49 is illustrated in Figures 54-56. As illustrated in Figure 54, the elastomer drift means 815 in this embodiment also includes a generally restangular member and insides within its upper surface a substantially radial groove 816, extending over its direction longitudinal, similar to slot 716 strips previously. However, a difference is that the elastomer-8 drift means includes a pair of projections 870 at opposite ends of the generally radial groove 816, which is provided with through-holes adapted to accommodate the pin 534 illustrated in Figure 49. Other The difference of that illustrated in Figure 49 is that the partular shape of the sleeve member adapted to be employed is the means of drift 815 corresponding to the configuration of the sleeve member 514 previously described and illustrated in Figure 33, such that the tubular portion 544 will collapse into the generally radial groove 816 between the two projections 870. The projections 870 in turn will collapse into the superable openings 550 formed in the sleeve member 514. The remaining portions of the diverting means 815 correspond to the means of derivation 715 dessritos previously. For example, the elastomeric drift means 815 may also include a number of concretes extending from its lower i? Profisie, which are accommodated within sorptive openings formed in the base portion of the base member similar to the base member 712 In addition, the base member may also include one or more reals that are drifting the means of drift 815 similar to the base member 712. In addition, the drift means 815 may be constituted by the variety of materials dessritos in relasion to the means of derivation 715, and of alternate sonfigurasiones to those illustrated. The operation of the elastomer drift means 815 is similar to the operation of the elastomer drift means 715. The primary difference is that the pin 534 operates to retain the elastomer drift means 815 through its deflection are both In addition, an additional spring force is provided from the two projections 870. In view of what has been previously established, it will be understood that the present invention has several advantages over conventional fasteners. An advantage is that the present invention provides an unscrewed extension of the sliding member, which allows the present invention to be used in aplissations where a greater "range of subjection" is desired; For example, when thicker packing is used, the sear is soldered at a greater distance than the fastener. Another advantage of the present invention is the position < • Cautiousness can be maintained within the device which improves both the durability and the operation of the fastener against the devices of the previous tress. Specifically, in subject-to-design clamping, the cam mesanism may be detached or otherwise insulated from its position within the opening of the sleeve member, which results in several problems being the device. One problem is that the damage of somponentes or the possible failure of the blushing can occur due to a resuspension in resistensia. Another disadvantage is that it is sisetensia frisslonal adisional in cam mesanism, which makes it more difficult for an operator to rotate the device for aserrojar or deseaserrojar. The present invention ensures that the cam mesanism is retained in planar relasion respecting the sliding member, in order to maintain the redress resistances and provide a uniform sanding and unfastening operation sonforme the cam mechanism is rotated. In addition, the eva retension sarasteristy of the present invention may be employed in a variety of different cam assemblies, for example those that embody a single member of disso or two or more member members. In addition, the cam retension sarasteristy of the present invention can be combined with the increased "clamping range" sarasteristics described above. Another advantage of the present invention is that a novel cam assembly is also provided which overcomes several cam configurations of multiple sonorous disks. In particular, cam assemblies of multiple sonar disks can be separated from each other under twill and which can allow the porsiones to desonate with each other and lead to a failure of the device. The present invention provides an assembly in which a member of integral discs of redused parts is provided, which is rotated to operate the device.

This partiscular cam assembly can also insorporate the previously noted annotated "rejection range" and / or "rejection range" charasteristics. Another advantage of the present invention is that a sompasto design fastener is provided, which also allows a sufficient amount of sawing force. In particular, in conventional fasteners, a spring member may be insorporated into the design to provide an additional steel strength to accommodate mounting inaccuracies and irregularities in the seal surface or packing. However, in this conventional case, the reefer extends beyond the fastener body requiring a larger "footprint" area to secure the fastener to a panel. In accordance with this, these types of devices have the disadvantage that they can not be used only with a limited area in order to mount the broom. In addition, often they are considered "too industrial aspesto" to be used in mushas aplisasiones for this same reason. In the present case, all faces are stennulated within the serpent girdle that provides both a smaller boll design and a pleasantly pleasing truss. used in order to ossulate the external spring member.The largest size of the handle member in these partiscular locations results with more insinuating devices. big. In addition, the stylized partis of the handle is limited to those designs that osultana the external spring. However, in the present invention, the handle member may be as much smaller in size as it is configured in any desired geometry since there is no external spring member required to ossulate. In addition, a sanctity sufisiente of force of acerrojamiento is proportional, even suando all the sarasterísticae are confined within the body of the bolt. Yet another advantage is that the sanctity of spring force or spring strength produced by the present invention may be varied depending on either physical geometry, material type or hardness of material, which is not ensured in the devices of the invention. previous technique In particular, in conventional models, the spring component is determined by the wire material and the geometry of a torsion loop, which limits the possible spring strengths in these devices. Another advantage is that the spring member in the present invention is surely retained in the boll. However, in devices of the previous shank, the spring can be deepened by the bolt due to the shape in which the spring is mounted. In addition, the connection of the sleeve member and the base member by a pin improves the overall resistances of the present invention. Another advantage is that the internal spring saracterlstisa of the present invention can be either one or any combination of the sarasteristisas previously.

Dessritas of the present invention or any device of the prior thesis. It will be recognized by those who are skilled in the technique that can be practiced by the modalities previously described of the invention, without departing from the amplitude and are inventive aspects of it. For example, the winged handle of the rotating means of rotation that can be replaced by alternate wing designs or alternate rotating members, such as a screwdriver slot in the dished member or a hexagonal sleeve attached to the top of the terser member of disso. Another example of this modification is that the base member can be lowered, such as in the U.S. patent. No. 2,853,752 or have integral integral side flange portions. Another example that can be provided is a member of sorredera modified in the U.S. patent. No. 4,746,151. An example of a further modifisation is an external wire spring, such as that illustrated in U.S. Pat. No. 2,820,995, which may be considered within any of the foregoing embodiments of the present invention. Therefore, it is assumed that this invention is not limited to the modality of partisularee deesritae, but that it is intended to highlight all the odifissions that are within the alsanse and spirit of the sorao invention is defined by the annexed claims.
