DETAILED DESCRIPTION

[0037] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

[0038] With reference to FIG. 1, a connecting system is generally indicated by reference number 10. According to several aspects, the connecting system 10 can be employed in a frame system 12 such as an exemplary vehicle door frame mounted to a motor vehicle (not shown). The connecting system 10 is used for example to connect a first member 16 such as an upper door frame member to a second member such as a vertical door frame member positioned proximate to a vehicle “B” pillar in a door closed position. The first member 16 and the second member 18 define a window opening into which is normally positioned a vertically movable window (not shown). The frame system 12 can also include additional frame members such as a stiffening frame member 22. The connecting system 10 can be used to replace a weld joint ground or machined at the junction between the first member 16 and the second member 18, and a subsequent weld joint which are presently used for coupling items such as the first member 16 to the second member 18 in motor vehicle door systems.

[0039] Referring to FIG. 2 and again to FIG. 1, the connecting system 10 includes a body 23 defining a connecting device, the body 23 or connecting device having a first leg 24 and a second leg 26 integrally connected to the first leg 24. The first leg 24 and the second leg 26 are oriented at an angle α with respect to each other, which according to several aspects defines a right or 90 degree angle. The angle α, however, can vary to be greater than 90 degrees or less than 90 degrees as necessary to accommodate different geometries of the first member 16 and the second member 18. The first leg 24 is frictionally received in a correspondingly shaped cavity 28 created in the first member 16. Similarly, the second leg 26 is frictionally received in a correspondingly shaped cavity 30 created in the second member 18. When the connecting system first leg 24 and second leg 26 are frictionally fixed in position as shown, a joint 32 between the first member 16 and the second member 18 is created, substantially locking together the first member 16 and the second member 18.

[0040] Referring to FIGS. 3A through 3C and again to FIGS. 1 through 2, according to several aspects, the connecting system 10 provides a connector assembly 34 having the first leg 24 and the second leg 26 integrally connected to the connector assembly 34. The first leg 24 and the second leg 26 both include a common rigid material core 36. A resilient polymeric material sleeve 38 substantially and commonly covers the core 36 of both the first leg 24 and the second leg 26.

[0041] As more specifically shown in FIG. 3B, the core 36 defines a geometric shape. The geometric shape of the core 36 can include any of multiple shapes including but not limited to a circle, an oval, a rectangle, a star, and the like. According to several aspects the geometric shape can include a cross having a first first core member 40 integrally connected to and oriented at a right angle with respect to a second core member 42. Each of the first and second core members 40, 42 can be rectangular shaped such as a portion 40a, or have other geometric shapes. Each of the first and second core members 40, 42 can also include additional features such as a concave shaped surface 40b.

[0042] As more specifically shown in FIG. 3C, the resilient polymeric material sleeve 38 can be pre-molded and then inserted onto the first leg 26 and the second leg 28, such that a first leg portion 44 covers the first leg 26, and a second leg portion 46 covers the second leg 28. If the resilient polymeric material sleeve 38 is pre-molded, it can also include one or more resilient fingers 48 that deflect to allow the first leg portion 44 and the second leg portion 46 to receive the first leg 26 and the second leg 28 respectively. According to other aspects, as will be discussed in reference to FIG. 6, the resilient polymeric material sleeve 38 can be over-molded onto the core 36 as a single, uniform layer, for example using an injection molding process. The resilient fingers 48 can be omitted or incorporated as a single member in the over-molded aspect.

[0043] Referring now to FIG. 4, before or after the connecting system 10 body 23 is frictionally received in both the first member 16 and the second member 18 an inner facing wall 50 of the first member 16 has dimples created therein, such as a first dimple 52 and a second dimple 54. The first and second dimples 52, 54 assist in mechanically coupling the first member 16 to the second member 18 using the connecting system 10, as will be described in greater detail in reference to FIG. 5. A similar inner facing wall 56 of the second member 18 also has at least one, and according to several aspects, third and fourth dimples (not visible in this view) created therein.

[0044] Referring to FIG. 5, and again to FIG. 4, a first recess 58 and a second recess 60 are created in an inside facing wall 61 of the first leg portion 44 of the body 23 of connecting system 10. Similarly, a third recess 62 and a fourth recess 64 are created in an inside facing wall 65 of the second leg portion 46. The first recess 58 is positioned to receive the first dimple 52 created in the first member 16 and the second recess 60 is positioned to receive the second dimple 54. Similarly, the third recess 62 is positioned to receive the third dimple created in the inner facing wall 56 of the second member 18, and the fourth recess 60 is positioned to receive the fourth dimple created in the inner facing wall 56 of the second member 18. As each dimple extends into the associated recess, an additional mechanical “lock” is created that enhances the frictional contact provided between the resilient polymeric material sleeve 38 and the inner surfaces of the first and second members 16, 18. This additional mechanical lock mitigates against the first leg 24 of the connecting system 10 body 23 releasing from the first member 16, and mitigates against the second leg 26 releasing from the second member 18.

[0045] Referring to FIG. 6, in one aspect of the connecting system 10 the resilient polymeric material sleeve 38 is over-molded onto the core 36 as a one-piece homogeneous covering, and is therefore substantially bonded onto outside facing surfaces of the core 36. In this aspect, one or more surfaces such as a concave surface 66 can be provided which match a corresponding shape of the core 36 such as the concave shaped surface 40b. According to several aspects the recesses such as the first recess 58 and the second recess 60 can extend either partially or entirely through a thickness of the resilient material sleeve 38 and in further aspects can also extend at least partially into the material of the core 36, for example at an area 68.

[0046] The resilient polymeric material sleeve 38 can also provide at least one and according to several aspects, multiple raised ribs, including a first raised rib 70, a second raised rib 72, and a third raised rib 74 each extending outwardly from a surface 76 of the resilient polymeric material sleeve 38. At least one and according to several aspects, multiple raised ribs such as a fourth raised rib 78 are oppositely directed from the first raised rib 70, the second raised rib 72, and the third raised rib 74, and extend outwardly from a surface 80 of the resilient material sleeve 38. The raised ribs are elastically compressible members which assist in maintaining frictional contact between the connecting system 10 and either of the first or the second members 16, 18. The raised ribs also allow for minor construction, installation geometry, or dimensional differences between the connecting device of the present disclosure, and the members to be joined such as the first member 16 and the second member 18.

[0047] Referring to FIG. 7 and again to FIG. 2, the core 36 can be made for example by a machining, casting or forging process, and can be made of a metal such as aluminum or steel. The core 36 includes a first arm 82 and a second arm 84. The second arm 84 is oriented at an angle β with respect to the first arm 82, which according to several aspects is substantially equal to angle α previously described in reference to FIG. 2. A relief notch 86 is provided at an inner corner defined at a junction between the first arm 82 and the second arm 84. The relief notch 86 is provided to allow full insertion of the first arm 82 within the first leg 24 into the first member 16, and full insertion of the second arm 84 and the second leg 26 into the second member 18.

[0048] Referring to FIG. 8, the connector assembly 34 of the connecting system 10 is shown positioned within the cavity 30 created in the second member 18. The cavity 30 is defined by an encompassing wall 88. The first raised rib 70, the second raised rib 72, and the third raised rib 74 of the resilient polymeric material sleeve 38 directly contact a first wall portion 90 of the wall 88 and thereby elastically compress. The fourth raised rib 78 directly contacts a second wall portion 92 and thereby elastically compresses. The second wall portion 92 is oppositely facing with respect to the first wall portion 90. Other segments of the resilient sleeve 38 can also come into direct contact with an inner facing surface 94 of the wall 88 to add further frictional engagement to help frictionally retain the connector assembly 34 of the connecting system 10 within the cavity 30 created in the second member 18. To avoid metal-to-metal contact, a gap 96 can be maintained between any exposed portions of the core 36 and the wall 88. To provide additional retention capability, an adhesive 98 can also be applied to outward facing surfaces of the connector assembly 34, which contacts and adheres to the inner facing surface 94.

[0049] According to several aspects, a connecting device for coupling first and second members 16, 18 includes a body 23 having a first leg 24 and a second leg 26 integrally connected to the first leg 24. The first and the second legs 24, 26 are oriented at an angle α with respect to each other. The first leg 24 and the second leg 26 both include a rigid material core 36. A resilient polymeric material sleeve 38 commonly covers the core 36 of both the first leg 24 and the second leg 26. The first leg 24 is frictionally received in a first member 16 and the second leg 26 is frictionally received in a second member 18 to couple the first member 16 to the second member 18.

[0050] The description of the invention is merely exemplary in nature and variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
