Definitions
- the present invention relates to improvements in assembly line type fastener assemblies wherein the fastener can be both quickly installed and released.
- the air bag mechanism typically is attached by four screws that are threaded into tubular standoffs that are attached to a plate that the airbag is secured to.
- the airbag is one of the last items to be assembled on the almost finished vehicle, its accessibility is very limited. Therefore the time required to assemble the airbag to the steering wheel assembly is longer than desired because the screws have to be inserted from behind the steering wheel.
- the convenience of installation is severely hampered due to the natural obstructions that accompany any automobile such as a gear selector lever, the turn signal stalk, the steering wheel post shroud and the proximity of the dashboard.
- the installation may also require the steering wheel to be rotated to a certain position in order to access all four holes; in addition the aligning of the screw to its mating threads in a blind application is difficult.
- the same problems occur during the check out cycle of a malfunction occurs or at a later time during normal servicing at the dealer's facility.
- the current practice of locating the holes for the airbag assembly and to install the four screws is slow and expensive.
- the reduction in time required to remove the installed airbag, i.e., due to a mechanical defect or after deployment is more than desired due both to the absence of a trained mechanic who normally installs airbags and to the cramped quarters which prohibits the use of power tools.
- the current time consuming system thus requires rotation of the steering wheel to certain positions to provide access and the unloosening and removal of the four screws.
- U.S. Pat. No. 5,011,355 to Motoshige discloses a pushbutton type fastener which utilizes a stud assembly snap-fitted into one of two panels to be joined, a mating socket being snap fit to the other panel.
- the two components are secured together by pushing a stud in the stud assembly toward the socket.
- the stud assembly is released from the socket by rotating the stud enabling a spring to urge the stud out of its engagement with the socket.
- the pushbutton fastener of the type illustrated in the Motoshige patent satisfactorily performs its function of releasably joining two panels together, the fastener requires a number of mechanical parts to perform its function, thus increasing its cost and complexity.
- certain applications such as the airbag installation/maintenance procedure noted hereinabove, requires access to the rear (non-head) portion of the fastener assembly to release it. Since the Motoshige type pushbutton fastener is releasable by rotating the head portion of the stud portion of the stud assembly, it would not be adaptable for use in that application.
- the present invention provides a fastener assembly for securing a first panel member to a second panel member in a spaced apart relationship.
- the fastener assembly comprises a tubular shank portion having first and second end portions and a cavity formed in said shank portion.
- a first spring member is secured on the outside of the shank portion, the shank portion having openings formed to enable hardened steel ball members to protrude therefrom.
- Inside the shank portion cavity is a stepped pin member spring loaded and held in place by a combination of the shank portion spring ball retention feature and step angles formed on the pin member. The ball members are in the retracted position until usage, held there by a first spring member.
- the fastener When the fastener is pushed into an aperture formed in the second panel member, the first spring member is compressed back toward the first end of said shank portion and moves away from the ball members it normally forces inward. As the fastener passes through the aperture, the ball members are still in the retracted position since the aperture diameter is approximately the same size as the inside diameter of the first spring member that previously contained it in the shank openings.
- a second spring member positioned behind the pin member, pushes the pin forward and forces the ball members to expand radially, thus securing itself to the second panel member completing the installation. At this point, there is a compressive load between the retracted first spring on the panel member and the radially expanded locked ball members.
- a tool is inserted in a recess formed in said pin member and the pin is pushed axially backward toward the first end of said shank portion, compressing the second spring member and allowing the ball members to retract inwardly.
- the fastener exits the hole due to the compressed first spring ejection load and the first panel member is free to be removed.
- the first spring member positions itself over the ball members to maintain them in the retracted position.
- the present invention thus provides a novel pushbutton type fastener that requires fewer components and wherein the panels joined together by the fastener can be quickly released by accessing the fastener at the end opposite its head portion, a feature required in many applications.
- the reduction in the number of components necessary to fabricate the fastener of the present invention increases reliability of the fastener while reducing its fabrication cost.
- FIG. 1 is an assembly view of the fastener of the present invention
- FIG. 2 illustrates the fastener of the present invention utilized to secure an air bag support plate member to a vehicle steering mounting support
- FIGS. 3(a) through 3(c) illustrate the steps of securing two plate members together and FIG. 3(d) illustrates how the two plate members are released;
- FIGS. 4(a) and 4(b) illustrate another embodiment of the fastener of the present invention.
- FIG. 1 an assembly view of a pushbutton type fastener 10 according to the present invention is illustrated in FIG. 1. While pushbutton fastener 10 can be utilized to join together various types of members, one important application is that shown in FIG. 2 wherein an air bag support plate member 12 is secured to a vehicle steering wheel support member 14, member 14 supporting steering wheel 16 via plate member 17. As has been noted hereinabove, it has been determined that for installation and repair purposes it is advantageous to enable access to the fastener 10 through its rear, or non-head portion end, due to the nature of the airbag installation.
- Fastener 10 comprises a stud 11 having a head 20 and a shank portion 22 with probe end 23, shank portion 22 having a hollow portion, or aperture, 24 formed therein as illustrated.
- a plurality of openings 26 are formed in the shank portion 22.
- Compression spring member 30 is formed around the outside surface of shank portion 22. As illustrated in FIG. 3(a), spring 30 is designed to have a portion 32 wherein the coils are diagonally wrapped around the shank portion and having a predetermined distance between each coil and a portion 34 wherein the spring members are formed in a close pattern about the holes 26 formed in the shank portion as illustrated.
- the spring coils are adjacent to one another and the axis thereof is substantially aligned with the axis of the fastener 10 as illustrated.
- head 20 and section 21 can be replaced with alternate configurations depending on the particular application for fastener 10, the only requirement being that a surface of sufficient dimensions be provided to engage one end of spring portion 32 since spring member 30 must be held in place on shank portion 22 during the fastener installation/removal process. This requirement can be met with a surface which is an integral part of fastener 10 or, for example, by a separate, adjacent plate member.
- Pin 35 Positioned within aperture 24 is a stepped pin 35 loaded (compression force applied thereto) by internal spring 37.
- Pin 35 comprises a series of cylindrical step portions 36, 38, 40 and 42 of differing diameters, joined by angled, or stepped, surface portions 44, 46 and 48, respectively, as illustrated.
- a hollowed end portion 49, or recess, in cylindrical portion 42 is provided to enable a driver access thereto for the reasons set forth hereinafter.
- Pin member 35 is loaded by spring 37 and held in place within aperture 24 by angular step 44 resting against ball members 28 (FIG. 3c).
- Ball members 28 are in the retracted position until usage, held there in place by portion 34 of spring 30.
- spring 30 is compressed back toward the head 20 of the fastener and moves away from ball members 28 it was initially forcing inward as shown in FIG. 3(a).
- the ball members are still in their retracted position because the diameter of the hole is approximately the same size as the inside diameter of spring 30 that once contained it.
- spring portion 37 pushes the pin forward (in the direction of arrow 60), forcing the ball members 28 to expand in the radial direction thus securing the fastener to the panel member 14.
- the spring 30 is now substantially compressed and internal spring 37 in its expanded position, pin member 35 being forced towards the probe end 23 of the shank portion of fastener 10.
- the bottom surface of the spherical ball members 28 are in contact with the surface of cylindrical portion 38 and angled surface 44 such that the ball members 28 have been forced to protrude from openings 26.
- the diameter of cylindrical portion 38 is selected such that ball members 28 protrude sufficiently to secure the fastener to panel member 14 yet provides enough available material adjacent openings 26 when the edges are staked to retain the ball members within aperture 24 notwithstanding large axial forces applied to pin 35.
- spring 30 applies a compressive force (pre-load) to the rear surface of panel member 14 and the radially expanded locked ball members 28.
- the holes 26 in the shank portion 22 are first formed of a diameter greater than a diameter of the ball members 26.
- the internal spring member 37 and the pin member 35 are then placed in the aperture 24 within the shank portion 22 and the ball members 28 are then placed in the apertures in the position shown in FIG. 3(a).
- a staking tool is used to reform, or stake, the edges of the holes 26 in an amount such that portion 27 of the holes 26 are smaller than the diameter of the ball members 28 thus preventing the ball members from exiting through the holes they are in, completing the installation.
- a driver tool 63 is positioned in recess 49 of pin 35 and pin 35 is pushed axially toward head 20 in the direction of arrow 64 as shown in FIG. 3(d). This action compresses spring 37 and enables the balls 28 to move down the angled surface 46 adjacent cylindrical portion 40. This action is aided by compression spring 30 which also as, due to its ejection load, to move the fastener in the direction of arrow 64 and thus to automatically eject the fastener panel member 14.
- fastener 10 is ejected from the hole in panel member 14 enabling, in the application described, the airbag unit attached to support plate 12 to be removed.
- spring member 30 positions automatically itself over ball members 28 to maintain them in the retracted position, enabling the fasteners to be reused.
- the inner stepped pin 35 in the embodiment shown in the previous figures is restrained from exiting aperture 24 by the interference of the ball members 28.
- the balls are captivated to the fastener by a staking process on the exterior shank portion of the pin.
- the location of the stepped pin against the ball can result in a major mechanical advantage causing the ball members 28 to be ejected from openings 26 if a sufficient load is applied axially to the inner stepped pin 35 when the airbag detonates.
- This load can force the balls radially outward and against the captivating staking portion, pushing the staked material away and allowing the ball members 28 to leave its original confines and also allowing the inner stepped pin 35 and spring 37 to exit their original location within aperture 24.
- FIGS. 4(a) and 4(b) the radial loading of the ball members 28 are eliminated by removing the inner pin retainer step portion 36.
- FIG. 4(a) illustrates the captivating step of the installation process with ball members contacting cylindrical portion 38' (equivalent to FIG. 3(c))
- FIG. 4(b) illustrating the release step with ball members 28 forced into the valley between surface portions 46 and 48, (equivalent to FIG. 3(d)). Therefore, any axial load or impact cannot affect the dislodging of the ball members 28.
- the ball staking process is only concerned with just holding the ball members 28 in place and not the effect of the inner pin step member 44 reacting on it.
- the pin member 35 and spring 37 are captivated by forming additional material, at the end of aperture 24 to a diameter that is smaller than the diameter of the pin member 35.
- the chamfered end 23 of the fastener has an angled portion 70, the resulting aperture diameter at this end of the fastener being smaller than the diameter of step portion 42.
- An additional technique for minimizing the radial type forces applied to ball members 28 if large axial forces are applied to pin member 35 is to increase the diameters of aperture 24 and cylindrical portion 36 and increase the angle of inclined portion 44.
- the contact point of the ball members 28 is such that the primary force applied thereto forces the ball members against the adjacent end portion 29 (FIG. 3(c)) instead of radially outward.
- the present invention allows an operator to quickly install the airbag unit from the driver's side, probe end 23 being chamfered to allow easy alignment.
- the operator takes the airbag assembly on panel 12 and presses it towards the matching plate where the fasteners are inserted into the mating holes.
- an audible click is heard which signifies installation is complete.
- the fastener of the present invention does not require the steering wheel to be rotated.
- a small diameter tool like a crosspoint screwdriver, simply be inserted into the end of the fastener opposite the head to engage the center pin therein.
- the fastener of the present invention can be used in other applications requiring pushbutton type fasteners, the pushbutton fastener of the present invention being less complicated and less expensive than prior art devices because there are fewer parts required for its operation.
- the release operation is very simple and as noted hereinabove and is accomplished by accessing the far end of the fastener, an arrangement which is required in many applications.
- the fastener is available for reuse in the field.
