I GOLF BALL RETRIEVER' Filed Aug. 15, '1967 INVENTOR. E A wwmv A. 67707;

United States Patent laims ABSTRACT OF THE DISCLOSURE There is herein disclosed a golf ball retrieving tool comprising an extensible shaft having a handle on one end and a ball gripping device on the other end.

Summary of invention This invention relates to a golf ball retrieving tool of the general type shown in US. 1,723,091; US. 2,549,257; and US. 3,038,751, for example. The invention provides a new and improved gripping device as well as new and improved extension shaft mounting means. The gripping device is in the form of a simple three-piece stamping or the like comprising a pair of identical oppositely facing gripping arms having spring finger portions attached to an extensible shaft and supporting jaw portions defining a ball pocket therebetween and being movable to an open ball receiving position against the bias of the spring fingers. A swingable trigger is mounted between the gripping arms and is engageable with the spring finger portions in the ball receiving position to hold the jaw portions open against the bias of the spring finger portions. Trigger actuating means in the form of a. ball engaging abutment plate portion is integrally formed on one end of the trigger and located in the ball pocket between the jaw portions in the open ball receiving position. As a ball is located between the jaw portions, it engages the abutment plate portion and causes the trigger to swing out of the ball pocket and to disengage from the spring finger portions whereupon the spring finger portions move toward one another and carry the jaw portions into gripping engagement with the ball. The extension shaft mounting means is in the form of a plastic insert having a generally cup shape with a cylindrical base portion frictionally retained in the end of a hollow extensible shaft and with an outwardly flared lip portion extending beyond the side surface of the extensible shaft into slidable frictional engagement with the interior surface of a hollow support shaft in which the extensible shaft is slidable.

Detailed description Referring now to FIGURE 1, apparatus for retrieving a golf ball or the like is shown to comprise a support shaft 12 having a handle 14 On one end and a necked down portion 16 at the other end. An extensible shaft 18 is adjustably slidably supported in shaft 12 and carries a ball gripping device 20. I

As shown in FIGS. 2-3, the ball gripping device comprises a pair of identical oppositely facing gripping arms Patented Jan. 14, 1969 22, 24 formed from sheet metal by a stamping operation or the like. The thickness of the sheet metal is substantially uniform throughout and of a size providing sufficient rigidity for the intended use while also providing spring-like characteristics as will be hereinafter described in detail. Acctaching means are provided at one end of the arms in the form of elongated narrow

width base portions

26, 28 which have a width approximately equal to the diameter of passage 30 in shaft 18.

Base portions

26, 28 are fixedly mounted in face-to-face abutting relationship, as by welding, and secured in passage 30 by suitable fastening means 32 such as a rivet or the like.

Side edges

34, 36 are located closely adjacent the inside surface of the shaft so as to prevent turning of the ball gripping device.

Jaw means 38, 40 are provided at the end of said gripping arms opposite the base portions and are connected to the base portions by spring finger portions 42, 44. Relatively short

first sections

46, 48 of each spring finger p01"- tion are bent outwardly at the end of the base portions to space outwardly diverging central sections 50, 52 which are connected to the relatively widely spaced jaw portions by connecting

sections

54, 56. The arrangement is such that the

jaw portions

38, 40 normally extend toward each other in a convergent manner and are more closely spaced than shown in FIG. 3 wherein the jaw portions have been moved to and are being held in a ball receiving position against the bias of the spring fingers. In the ball receiving position, the jaw means extend substantially parallel to one another and to the

base sections

26, 28. When the restraining force is removed with ball between the jaw means, the spring fingers move the jaw portions into gripping engagement with the ball in a gripping position intermediate the ball receiving position and the normal unstressed position.

Jaw portions

38, 40 are provided with ball seats 58, 60 formed by circular aligned

openings

62, 64 and out-turned

circular flanges

66, 68. In the ball receiving position, the jaw portions form a ball receiving pocket larger than the ball by being held apart a distance greater than the width or diameter of the ball. When the jaw means have moved to the gripping position, they form a ball pocket the same size as the ball which protrudes into both

openings

62, 64 and is held by the surrounding seats 58, 60 which are then spaced apart a distance less than the width of the ball.

Jaw holding trigger means 70 are provided to hold the jaw portions in the ball receiving position until a ball is located in the ball pocket between the jaw portions and in alignment with the

openings

62, 64. In the preferred embodiment, the trigger means comprises a swingable member mounted between and supported on the arms 22, 24. The trigger member swings between the arms in a direction transverse to the direction of movement of the jaw portions. Thus, the trigger member is movable in either direction and a pair of opposite access openings to the ball pocket are provided. A ball engaging abutment portion 72 is located substantially centrally of the ball pocket and is connected by an elongated narrow width intermediate portion 74 to a support portion 76 located between arms sections 50, 52. Opposite outwardly extending support legs 78, 80 extend through opposite aligned support apertures 82, 84 in arm sections 50, 52. Retaining

tabs

86, 88 extend transversely beyond the adjacent edges of the support apertures in overlapping abutting engagement with the adjacent side surfaces of arm sections 50, 52. The arrangement is such as to provide cooperating bearing surfaces on the support legs and on the adjacent edges 90 of apertures 82, 84 to swingably support the trigger for swinging movement in either direction.

Holding means are provided for holding the arms in the ball receiving position and for releasing the arms for movement to the ball gripping position when a ball is properly positioned in the ball pocket. The arrangement is such that the arms are not released until the ball is properly positioned. Furthermore, sulficient resistance to movement of the trigger is provided to enable the grip ping device to be maneuvered relative to the ball without prematurely releasing the arms before the ball is properly positioned. Nonetheless, the holding means is simple and requires no additional parts it being integrally formed on the trigger and the arms by provision of inwardly deflected tab members 96, 98 integrally connected along one edge to the arms. The inner edges of the tabs form abutments engageable with opposite sides of the central position of the trigger as at 100, 102. Tabs 96, 98 extend equally on opposite sides of the trigger in the ball receiving position and have a length so as to prevent closing of the arms until a ball is located in the ball pocket in alignment with the jaw seats 58, 60 and jaw openings '62, 64. It will be seen that the provision of circular jaw seats and openings permits a self-centering action as the jaw arms close and thus provides a certain margin of error.

Another feature of the present invention resides in the manner and means of connecting the extensible shaft 18 to the support shaft 12. As shown in FIGS. 4 and 5, shaft 18 is a tubular cylindrical member having an outside diameter approximately equal to the inside diameter of necked down portion 16 so as to be slidable therethrough. The inside diameter of the tubular cylindrical support shaft 12 is substantially larger than the outside diameter of shaft 18 as indicated by clearance 106. Retaining means 108 in the form of a one-piece plastic plug-like member is fixedly mounted in the end of shaft 18 and is designed to prevent inadvertent removal of shaft 18 from shaft 12 and to hold the extensible shaft 18 in any adjusted position relative to support shaft 12. Plug 108 is formed from plastic material in a cup-like configuration comprising a cylindrical hollow base portion 110 and an outwardly flared inwardly flexible lip portion 112 of truncated conical shape. Base portion 110 has an outside diameter slightly larger than the inside diameter of shaft 18 and is hollow to provide suflicient compressibility to enable the base to be inserted in the end of shaft 18 and fixedly frictionally retained therein. Lip portion 112 extends outwardly beyond the outer surface of shaft 18 and, in its normal unstressed condition, has a diameter at the outermost edge 114 greater than the inside diameter of shaft 12. Thus, when assembled, lip 112 is under compressive stress whereby shaft 18 is prevented from moving freely relative to the support shaft 12 but is slidably movable by manually applied adjusting force and will be held in any adjusted position by frictional forces. To provide sufficient flexibility to permit assembly and disassembly as well as the desired holding forces, lip 110 is provided with opposite axially extending slots 116, 118. To provide suflicient rigidity to prevent inadvertent removal of the shaft 18 and plug 110 through the necked down portion,

ribs

120, 122, 124, 126 are equally spaced around the interior of the plug and extend from the rubbing edge 114 of the lip portion to the end wall 120 of the base portion. The cross-sectional configuration of the plug is substantially cylindrical in the base portion and hexagonal in the lip portion. In the preferred embodiment, the slots 116, 118 are located at opposite apexes and the ribs are equally spaced at 90 and located substantially centrally of opposite flat surfaces as shown in FIG. 5.
