Definitions

  • a striking device for striking a ball or shuttlecock or the like includes a striking means, preferably in the form of an arrayof string elements supported in a frame.
  • the frame has connected thereto a handle.
  • the striking means is yieldable in a direction perpendicular to the plane occupied by the striking means when a ball or shuttlecock or the like impacts against the striking means.
  • Modifications include helical springs provided outside the frame and movable segment members are used outside of spring means. Tube projections of segments are thickened at inner ends and are pressed into bores of the frame. Rotatably mounted pins optionally are mounted in a heart piece between the frame and handle.
  • the present invention relates to a device for hitting a ball, shuttlecock, or the like. Such a device may be used for example in playing tennis, badminton or other similar games.
  • the hitting surface normally is made up of strings possessing a certain inherent elasticity. This elasticity enables a ball to be hit by the racket to bounce off elastically, but since the inclination of the hitting surface to the handle varies during impact it may be difficult to achieve an exact aim using the racket.
  • FIG. 1 illustrates in plan view of the racket according to the invention.
  • FIG. 2 shows a section taken along the line 22 of FIG. 1.
  • FIG. 3 represents a section taken along the line 3-3 of FIG. 1.
  • FIG. 4 is a section taken along the line 44 of FIG. 3.
  • FIG. 5 shows a detail view of a frame of another embodiment of the invention, mainly in front elevation, but partly in section, the movable members and springs having been withdrawn from the frame.
  • FIG. 6 shows a detailed plan view of the embodiment shown in FIG. 5, one movable member and spring having been entirely removed.
  • FIG. 7 shows a part of a different frame in front elevation, the movable member and springs having been withdrawn from the frame.
  • FIG. 8 shows a detail of a region of the cross-piece of another embodiment of the invention.
  • the device for hitting a ball according to the present invention is characterized primarily in that the elastic means are so arranged and designed that the hitting surface during its movements will not change its position relative to the said handle.
  • a plurality of retainers are provided on the support. These retainers are segments retaining the resilient mounting means or springs of steel, rubber or other material against the support.
  • the hitting means is preferably defined by a frame, while the resilient mounting means are arranged to act between the frame and the support, while alternately the retainers comprise members mounted to be movable relative to the support.
  • the resilient mounting means are arranged to act between the support and said movable members.
  • the resilient mounting means may be received in apertures in the support, each movable member being provided with an individual projection engaging the or each respective mounting means arranged to act between the support and the respective movable member, and being provided with a groove on the side of the movable member opposite the or each projection, the groove receiving a string connecting portion joining adjacent strings of the hitting means.
  • the hitting means may comprise an array of strings, the ends of the strings being provided with retainers retaining the mounting means against the support.
  • FIGS. 1 to 4 show a racket in which resilient mounting means or helical springs 2.3 are inserted in recesses 25 provided on a frame 24 and cushion the center strings in each direction to provide a control resiliently cushioned area of the striking surface.
  • movable members in the form of retainers, holding means, segmental members or segments 26 which have projections 27 on their inner side, the projections 27 extending into the springs 23.
  • the projections 27 may, if desired, be of hollow construction.
  • the retainers or segments 26 are provided with a groove 28 to receive a connecting portion between two of the strings 29 forming a part of the hitting means and defining a portion of the hitting surface.
  • the segments 26 are further pro vided with tube-like extensions 30 (FIG. 4) through which the strings 29 are passed.
  • the individual strings of the racket may, in this embodiment and in the other described embodiments all be integral with one another, or alternatively some or all of them may be constructed of separate lengths of material.
  • the segments 26 are arranged in a groove 31 of the frame 24.
  • a clearance f is provided between a base surface 32 of the groove 31 and a flange of the segments 26. The clearance f determines the maximum length which the springs are permitted to adopt.
  • the segments 26 are captive in the frame, this being a preferable feature of the racket.
  • the tube-like projections 33 of the segments 34 are at their inner ends provided with thickened portions 35, the outer diameter of which is somewhat greater than the diameter of the bores 37 provided in the frame 36.
  • the segments 34 may consist of thermoplastic material so that for the insertion of the segments 34 into the frame 36 the tube-like projections 3.3 need to be heated only slightly in order to permit the thickened portions 35 to yield sufficiently to enable the projections 33 to be pressed into the bores 37.
  • the segments 34 may be constructed of an elastic material.
  • the frame 36 is also provided with bores 38, to receive the helical springs 39.
  • a sufficiently short spring 39 and a corresponding design of the segments 34 are employed, a construction can be realized according to which the segments 34 do not project outwardly beyond the outer edge region of the frame 36. With this arrangement, damage to the segments 34 during a possible impact of the racket with the ground can be avoided.
  • the segments 34 are provided on their outer side with a groove 40 to receive the connecting portions between pairs of strings 41.
  • FIG. 7 there is shown a part of a frame 42 into which a different segment 43 can be inserted.
  • the segment 43 can receive three helical springs 44.
  • strings 46 run approximately perpendicularly with regard to the local periphery of a frame part 47 adjacent the cross-piece 45 and thus also perpendicularly with regard to the segments 48 inserted into the frame part 47.
  • the pins 49 may be rotatably mounted.
  • pins 50 may be provided, the crosssectional shape of which is that of a segment of a circle.
  • the segment 48 is captive on the frame part 47, the segment 48 being connected to the frame part by means of screws 51.
  • the direction of travel of a ball hit properly by string of the device may be determined only by the direction of movement of the handle.
  • the resilient mounting means are adjustable as to their resiliency, it is possible to set the resiliency of the hitting surface at a value which may be most convenient or suitable to the respective player using the device.
  • the resiliency of the hitting surface may be determined only by the inherent elasticity of the strings, in which case the resiliency decreases considerably toward the edge regions of the device so that the center of the hitting surface has a great resiliency than the edge regions. This is due to the fact that the strings can yield in a direction perpendicular with regard to the plane of the hitting surface to a greater extent in the center than at the edge regions.
  • the resiliency of the whole hitting surface may be equal.
  • movable members in the form of segments are used, it is possible to equip existing ball hitting devices so that they will operate in a manner similar to that of the described embodiments provided with segments.
  • the segments may be so constructed that each one cooperates with one or more springs or other resilient mounting means. Expediently, however, at least two mounting means are received by each segment.
  • the mounting means may comprise springs constructed of steel, rubber or other material.
  • Helical springs are a convenient form of spring for use in the described embodiments. However, springs of other shapes than cylindrical may be used. Furthermore, either tension springs or compression springs may be em ployed.
  • the describedembodiments may permit low-friction movement of the hitting surface relative to the handle thereby maintaining the stress applied to the arm of a player at a low value.
  • a racket comprising an open, peripheral head frame having its ends extended beyond one side at its throat portion and continuing parallel to each other to form a handle for said racket, and a cross-piece extending between the sides of said head frame at said throat portion and complementary to the opposite side of said head frame, thereby forming a closed loop head frame, at least said head frame and throat portion having an external channel formed therein, said head frame and throat portion being formed with string holes therethrough, an array of strings extending in longitudinal and transverse directions across said peripheral head frame to form a striking surface, a plurality of the centrally located strings in at least the longitudinal direction extending from said throat portion to said opposite side of said head frame, said centrally located strings being connected to said head frame by first string connecting means, said first string connecting means connecting said centrally located strings to said frame comprising resiliently cushioned segments in said channel forming connections for said strings, said segments having inner surfaces and outer surfaces, coil springs seated in said channel between said frame and the inner surfaces of said segments to cushion movement of said segments and resiliently tension said central
