CN-122028958-A - Racket for sports game

Abstract

A sports racquet according to the present disclosure includes a head portion having a head thickness and including a front panel and a rear panel, each of the front panel and the rear panel having a concave ball striking surface defined by a continuous curvature. The handle is connected to the head. The frame defines a periphery of the sports racquet. The frame includes a head section extending around the head, a handle section extending along the handle, and a transition section joining the head section and the handle section. The head section and the handle section have a first frame thickness and the transition section includes ribs having a second frame thickness. The second frame thickness is greater than each of the first frame thickness and the head thickness. The ribs are operable to resist bending and twisting of the head relative to the handle.

Description

Racket for sports game Cross Reference to Related Applications The present application is a non-provisional patent application claiming priority from U.S. provisional patent application serial No. 63/592,925, filed on 25 of 10 of 2023, and entitled "Pickleball PADDLE WITH Geometric Features that Improve Acoustics and Performance (picoracquet with geometric features that improve acoustic and performance)", the entire disclosure of which is incorporated herein by reference. Background The present disclosure relates to rackets for sports games such as picoballs, board tennis and the like that provide a uniquely designed concave face plate and an improved structural transition section in the "throat" transition region connecting the head of the racket and the handle. Description of the Related Art Peak ball is a versatile and rapidly developing sport played on badminton pitch-sized pitch with a 34 inch net. The picoball uses plastic balls and rackets made of various different materials, making it suitable for indoor or outdoor play. The game is beginner friendly, but the competition may be very intense. Social and cross-generation attractions of the race have won a follow-up of enthusiasm. The picoballs can be played singly or in pairs, and have simple and easy-to-learn rules, extremely low clothing requirements and affordable portable equipment. Peak balls are popular in schools and adult communities, which are managed by the United states Peak ball Association (USAPickleball. Org). Picket and other racquet sportsmen often pursue racquet designs that improve impact sound, feel, performance, error resilience, and durability of racquets with the ability to be tailored to their preferences. Racket is commonly manufactured using a variety of materials, layers and components, which may include wood, metal, fiberglass, carbon fiber composites, foam, plastics, rubber and resins. The method of manufacture may include lamination, thermoforming, injection molding, CNC machining, encapsulation molding, grinding, polishing, painting, decorating, assembling, and combinations thereof. After impact with a picoball racquet, the behavior of the picoball racquet ball is generally defined by the speed, orientation and path of the racquet, as well as the structure, mass and surface characteristics of the racquet. In recent years, the pick ball has been attracting attention due to noise problems, which are mainly caused by sounds generated when a racket hits a ball. In many communities, there is a dispute between a pitch player and a resident nearby the pitch. In some communities, the pitch has been closed due to noise complaints. Furthermore, the picoballs "hit" (contact between the racquet and the picoball) when compared to tennis racquets and similarly sized balls, often hit off-center due to skill level, game speed, and the relative size of the racquet head. The "center" may be defined by the center of gravity or the center of impact of the racquet or a combination of contemplated thereof. The center of gravity of the racquet is the center of mass distribution of the racquet, and the center of impact of the racquet is determined by the geometry and vibration response of the racquet. The rotation of the head upon an off-center impact is generally related to the center of gravity of the racquet, the mass characteristics, the distance from the impact to the center of gravity of the racquet, and the torsional and deflection resistance that the mobilizer may provide when the ball is in contact with the racquet. Fig. 1 illustrates a conventional example of a complete picogram ball racquet 10. The picoball racquet 10 generally includes a handle section 20 and a head section 12. The handle 20 generally includes a flared section at the handle end 22. In this case, the handle molding 22 is mounted to the handle 20 section of the racquet 10. The head 12 generally includes an inner core 18 having a face plate surface 16 on an opposite side of the head 12. The core 18 may be formed of a polymeric honeycomb material, however, the core may be made of other alternative materials. There is a transition region or throat 14 between the substantially parallel sides 24 of the head 12 and the handle 20, the transition region or throat 14 may or may not include a protective edge guard mounted around the periphery. The periphery of the racquet is defined as the outer edge and side walls of the faceplate and does not include edge guards that may or may not be present on the racquet 10. The throat portion 14 is considered the weakest structural area of the conventional picoball racquet 10. U.S. Pat. No. 11,597,169 B2 to Simmons describes a Peak ball racquet and method of making the same. As part of the process for manufacturing racquet, simmons discloses a plastic or composite molded material that is wrapped around a tubular bladder or center and placed in a mold to form the racquet frame. In some embodiments, additional composite material is wrapped a
