CANTILEVER TYPE BALL BUMPER Filed Dec. 13, 1966 I 41/ 56 62 111A! 11/ II III INVENTOR.
United States Patent 0 3,391,937 CANTILEVER TYPE BALL BUMPER Herman L. Seiden, Skoltie, 112., assignor to Lion Manufilcturing Corporation, Chicago, 11., a corporation of I inois Filed Dec. 13, 1966, Ser. No. 661,494 8 Claims. (Cl. 273-129) ABSTRACT OF THE DISCLOSURE The improved bumper structure is characterized in that it consists in a molded bumper body of synthetic plastic material in the form of a lightweight shell having only one open side with internal supporting rib, web and post formations constituting supporting lands exposed at that side, including snap-in formations bordering the margins of the opening at such side engageable with a rigid cantilever base plate fitting into and closing the opening against the ends of the post formations and lands, the base plate having a spindle afiixed thereto at one end for cantilever support of the body with an end of the spindle penetrating one post formation for added support and centering and securing means offset from the spindle and penetrating the plate to engage another post formation, whereby the body is releasably attached to the plate in a rigid and sturdy assembly.
This application discloses and claims subject matter disclosed and claimed in a copending application Ser. No. 323,660, filed Nov. 14, 1963, now Patent No. 3,298,961. The invention hereinafter described relates to the construction of ball bumpers for use in ball-rolling games and has for its principal object the provision of structural improvements particularly adaptable to the fabrication of the so-called cantilever type of bumper which is commonly employed in a pivotal manner for operation as a ball reprojector in which function the bumper is caused by suitable electromagnetic or like means to swing sharply and strike a blow against a ball to alter its course on a ball-rolling panel, the ball being generally of steel and subjecting the bumper to severe stresses which become destructive over a period of time and require replacement, among other parts, of the ball-engaging bumper body.
When bumpers of the class described are employed as reprojectors, electromagnetic drive means, for example a solenoid is frequently employed as the source of pivoting or driving power; and to minimize the loading thereof while procuring maximum striking force and speed in the response of the bumper in such reprojecting action, it is desirable to achieve maximum strength in the bumper body with minimal weight in the entire moving assembly.
The several objects and aspects of novelty and utility characterizing the invention may be realized in the preferred embodiment thereof described in detail hereinafter in view of the annexed drawing in which:
FIGURE 1 is a fragmentary sectional view of a ballrolling board with the improved bumper mounted thereon for actuation by rcprojecting drive mechanism;
FIGURE 2 is a bottom plan view of the apparatus seen in FIGURE 1;
FIGURE 3 is an exploded perspective view of the components of a preferred form of the bumper assembly;
FIGURE 4 is a plan view of the open bottom of the bumper body;
FIGURE 5 is a vertical sectional detail lengthwise through the bumper structure with parts of the spindle broken away;
FIGURE 6 is a lateral section of the structure seen in FIGURE 5.
In its reprojccting adaptation seen in FIGURE 1, the
Fatented July 9, 1958 bumper 10 is mounted upon the upper ballrolling surface of a playfield panel 11 by shaft means 12 extending downwardly through a bushing 13 to a level beneath the panel where the shaft engages in the hub member 14 of a crank lever 15 in which it is secured as by a set screw 16, said crank being journalled in a mounting plate 17 forming part of a driving unit.
The driving means may be of the type disclosed in US. Patent No. 3,298,691 (Ser. No. 323,660, aforesaid) comprising an electromagnetic solenoid 28 secured on said base plate 17 and having a plunger 19 attractable thereby and pivotally connecting with said crank member 15 for operation to pivot the latter when the solenoid is energized, whereby to pivot the hub portion 14 and the cantilever bumper spindle 12 afiixed therein, thereby swinging the bumper body 10 abruptly to impart a blow to a ball l3 within strikin range thereof.
As viewed in FIGURE 3, the bumper structure 10 comprises a body 36 which is of an elongated configuration tapering downwardly from a somewhat rounded dome portion 31 to an outwardly-flared bottom skirt portion 32 bordering a bottom opening 33 exposing the hollow interior of the body' Thus, the bumper body is a substantially closed shell having only one open side constituting a bottom entry adapted for snap-in interfit with the cantilever supporting and pivoting means to be described.
Externally, near the dome or top, the molded shell is provided with a circumambient groove 34 which seats a resilient bumper or rebound band 35, FIGURES 1, 5 and 6, having a diameter sufiicient to cause outer peripheral portions thereof to stand outwardly from the body for engagement by the ball -B, it being observed that the skirt portion 32 flares outwardly into the region which underlies the curved part of the ball so that upper portions of the ball engage the band rather than the bumper body itself, the band being intended to absorb some of the shock of impact when the ball strikes the bumper or vice versa when the bumper moves in reprojecting action, but is also intended to cause a ball striking the bumper in its stationary condition to rebound therefrom.
Internally, certain structural formations are provided for stren thening the shell and interconnecting with certain cantilever supporting and rotating means, including, FIGURES 3, 4 and 5 particularly, a pair of posts 36 and 37 extending from the dome portion normally to a plane included through the open portion or body of the shell, said posts having free end portions constituting lands terminating substantially at said plane or at a point close to the opening for supporting engagement with a cantilever plate 38 in a manner further explained hereafter.
The posts 36 and 37 are disposed near one of the longitudinal ends of the body in the region of cantilever support, but there is a third post-like formation 39 (FIG- URES 4 and 5) adjacent the opposite end thereof which affords another land or support for opposite end regions of the plate 33, or conversely, support for the body upon the plate.
Situated at a point between the opposite longitudinal ends of the body shell is a lateral cross web 49 integrally connecting with the dome portion and parts of the opposite adjoining side walls, and as viewed particularly in FIGURES 3 and 5, the upper margin d1 of this web terminates at a point substantially below the free ends or lands of the other posts, that is to say a substantial distance below the lip margins of the shell at the open side thereof, so as not to prevent some yieldability of the relatively thin side wall portions of the shell in a lateral sense in this region to effectuate the snap-action engagement and disengagement of a number of longitudinally-extensive integral snap-in ribs 42, FIGURES 3 and 4, disposed close to the margins of the open side of the body so as to overlie edge portions of the plate 33 when the latter is inserted in, or withdrawn from assembled relation with the body member.
However, what may be regarded as slender rib-like remnants or continuations 43 of the web extend to the level of the post lands, and the extremities of these ribs or remnants constitute additional lands 43X contributing to the seating of the plate 38.
As viewed in plan, FIGURE 4, the contour of the bumper body is of an elongated pear-shape with wider portions at the end thereof which is engaged in cantilever support, the opposite free end tapering somewhat to a point, as is customary in this class of bumper, because such devices are commonly installed on a tilted ball-playing field or panel down which the played balls roll with more or less speed depending upon how and in what directions they have been impelled; and frequently the narrower or pointed end of such a bumper body will be located at a lower position down the incline of the panel than the fixed end, so that the slower balls engaging the portions thereof at the higher level (and not rebounding) will tend to follow and hug along the side thereof leading to the narrower end without stalling or slowing up appreciably, whereby to enhance the overall ball action.
Therefore, the base plate 38 is shaped conformably, as seen in FIGURE 3, and dimensioned so as to fit substantially flush within the borders of the shell at the bottom thereof, as in FIGURES 5 and 6, to snap beneath the snap-in ribs 42 with the inner face of the plate engaging the several dispersed lands afforded by the free ends of the posts 36, 3'7 and 39, the side walls of the shell yielding for this purpose, as previously explained, it being further provided that the plastic material of which the body shell is molded will preferably not be entirely rigid but will have some inherent yieldability not only aiding the aforesaid snap-in action, but also rendering the body less subject to rupture from the shock of repeated ball impact.
The bumper structure is completed by provision of the supporting shaft or spindle 12 in fixed attachment with one end of the plate 38 and having a major portion 12X of its length of a predetermined diameter and projecting normally to the plane of the plate a considerable distance therebeyond to serve as a pivot shaft, while a shorter end portion 12Y, which is of reduced diameter, projects a distance beyond the opposite or inner face of the plate for entry into a bore provided in the post 37, by which the bumper body is further registered and stabilized in attachment to the plate and the cantilever spindle support.
Means for releasably locking or fixing the plate in assembly with the bumper body comprises a pin or screw 44 passing through a hole 45 in the base plate and engaging in a bore in the subjacent post 36. In this condition of assembly, the base plate fits and is drawn against all of the post ends and lands, whereby the body is securely supported by the spindle, the shell-like structure being reinforced against the stress and shock of repeated ball impact by the internal and external configurations described.
