Description

Technical Field

[0001] This utility model relates to the field of children's toy ball technology, and in particular to a grip strength playground ball. Background Technology

[0002] Balls are a common toy for children, and they are very helpful for developing children's fine motor skills and overall coordination.

[0003] Currently, most commercially available toy balls targeting children aged 3 and up typically have an inflatable rubber bladder with a layer of polyester fiber yarn in between. This results in a hard ball, which can cause injury when children throw or grab it at high speeds. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a grip strength playground ball that eliminates the inner core of the string and adopts a structure in which a rubber surface is directly wrapped around the outer part of the inner bladder. The overall structure is simpler and the ball is softer, thereby reducing the risk of injury to children.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A grip strength playground ball includes an inner bladder and an elastic layer covering the outer layer of the inner bladder. The outer surface of the elastic layer has an array of gripping pits, which are integrally formed on the elastic layer.

[0007] The inner liner is an inflatable liner.

[0008] As a further improvement to the above technical solution:

[0009] The outer surface of the elastic layer has a coarse sandy surface, which consists of rubber particles integrally molded onto the surface of the elastic layer.

[0010] The depth of the gripping recess is greater than the thickness of the coarse sand surface but less than the thickness of the elastic layer.

[0011] The gripping recesses are set in several rings, with adjacent rings of gripping recesses staggered.

[0012] The spacing between any two adjacent pits is the same.

[0013] The spacing between any two adjacent pits ranges from 0.5cm to 1.5cm.

[0014] The diameter of the gripping indentation ranges from 0.5cm to 1cm.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention adds a concave-convex structure to the mold, so that the rubber surface has pits suitable for finger gripping; it also designs tiny dots in the mold to give the rubber surface a frosted feel, increasing friction when gripping and preventing slippage.

[0017] This product can be used not only for children to play with individually, but also for throwing and catching among themselves, increasing the playability and entertainment value. When playing in a group, the ball can be thrown further than when played individually. The soft ball significantly reduces pain upon contact with the body; at the same time, the coarse sand surface and gripping grooves throughout the ball make it easy for children to grip from any angle, making it more suitable for single or group play environments for young children than conventional balls.

[0018] The ball features a soft inner liner that directly covers the rubber surface, eliminating the need for an internal winding core. This makes the ball softer and less likely to cause injury to children. It is also lighter, making it suitable for children aged three and up to play and exercise. The ball has moderate elasticity, preventing it from bouncing too high or too fast and hitting children, while also ensuring that insufficient elasticity doesn't diminish the fun of playing with it.

[0019] The surface of the ball of this invention is provided with many gripping recesses, which makes it easy for children to grip the ball and is adapted to children's hand movements;

[0020] The rough surface and gripping pits increase the friction between the ball and the outside world. Even in home or shopping mall environments such as smooth floors, the ball can maintain sufficient friction with the ground, reducing the possibility of children slipping and falling when chasing the ball.

[0021] The internal structure of the sphere in this application is less than that of a conventional structure. During prolonged play, the stress on the internal structure of the sphere is also less, and the probability of local stress-induced damage is relatively smaller. Attached Figure Description

[0025] The components include: 1. Inner liner; 2. Elastic layer; 3. Grip recesses; 4. Coarse sand surface. Detailed Implementation

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figures 1-3As shown, the grip strength playground ball of this embodiment includes an inner bladder 1 and an elastic layer 2 covering the outer layer of the inner bladder 1. A plurality of gripping pits 3 are arrayed on the outer surface of the elastic layer 2, and the gripping pits 3 are integrally formed on the elastic layer 2.

[0028] The inner liner 1 is an inflatable inner liner 1.

[0029] The outer surface of the elastic layer 2 has a coarse sand surface 4, which is a rubber particle integrally molded on the surface of the elastic layer 2. The rubber particles are formed by the concave and convex particle shape constructed in the mold, and a uniform coarse sand surface can be obtained after demolding.

[0030] The depth of the gripping pit 3 is greater than the thickness of the coarse sand surface 4, but less than the thickness of the elastic layer 2.

[0031] The gripping recesses 3 are set in several circles, with adjacent circles of gripping recesses 3 being staggered.

[0032] The spacing between any two adjacent gripping pits 3 is the same.

[0033] The spacing between any two adjacent gripping pits 3 is between 0.5cm and 1.5cm.

[0034] The diameter of the gripping pit 3 ranges from 0.5cm to 1cm.

[0035] The inner liner 1 is made of spherical foam.

[0036] The specific structure and advantages of this application are as follows:

[0037] This application proposes a ball toy for children aged 3 and above to play and exercise. Considering that children have weak limb control and small grip strength, this application improves the surface and inner bladder of conventional ball toys to make the ball toy more suitable for younger children.

[0038] The improvement to the inner liner 1 lies in eliminating the use of the wound inner liner 1 in conventional balls. Conventional rubber toy balls typically have an inflatable rubber inner liner with a polyester fiber winding in the middle, providing a certain weight and rigidity. This wound inner liner 1 is usually used in adult or youth ball games to increase the ball's weight and throw it a greater distance. However, for young children, toy balls are generally not used for competitive throwing, so the use of winding is unnecessary.

[0039] As an alternative implementation of this application, the inner bladder 1 of the sphere is an inflatable inner bladder 1, such as an inflatable rubber bladder. After inflation, the rubber bladder is filled with air and covered with an elastic layer 2. The sphere is lightweight and soft, making it less likely to injure children.

[0040] Another improvement of this application is that an elastic layer 2 with a certain surface roughness is used, and gripping pits 3 are provided on the elastic layer 2 to help children grip the ball.

[0041] Elastic layer 2 is made of rubber. Tiny dots are set within the molding die of the rubber layer. During rubber molding, these tiny dots form the coarse sand surface 4 of elastic layer 2, giving the rubber surface a frosted feel. Without harming children's skin, it effectively increases surface roughness, increasing friction when gripping and preventing slippage. Furthermore, the rubber particles have a certain degree of softness, making it relatively safe; it only feels slightly rough to the touch.

[0042] With the coarse sand surface 4 in place, multiple equally spaced and staggered grasping recesses 3 are provided on the elastic layer 2. The size of the grasping recesses 3 is designed according to the hand size of children over three years old. The grasping recesses 3 are required to be able to accommodate the child's fingertips. Ideally, each adjacent grasping recess 3 should allow at least three fingers of each of the child's hands to fall into the grasping recess 3. That is, the distance between adjacent grasping recesses 3 should not exceed the distance between adjacent fingers when the child naturally extends their five fingers.

[0043] Therefore, in one embodiment of this application, the spacing between any two adjacent gripping recesses 33 is in the range of 0.5cm-1.5cm, and can be the endpoint values ​​of 0.5cm and 1.5cm, or the intermediate values ​​of 1cm and 0.8cm.

[0044] The diameter of the gripping pit 33 ranges from 0.5cm to 1cm. The endpoint values ​​of 0.5cm and 1cm can be used, or the intermediate values ​​of 0.6cm and 0.8cm can be used.

[0045] The advantages of this application are that it reduces the number of yarn layers, resulting in a simpler structure and cost savings; the sphere is lighter and softer, making it easier for children / toddlers to grasp, and reducing the impact of the hard winding core on children.

[0046] This application applies to both single-person slapping and multi-person throwing scenarios. In single-person slapping play, the child throws the ball on the ground once or slaps it back and forth. In this single-person play scenario, the ball travels a short distance, so even if it hits the child, the injury and pain are minimal.

[0047] In multi-player play scenarios, multiple children throw balls at each other, resulting in a longer trajectory, greater inertia, and greater impact force. The proposed method, which eliminates the inner bladder and winding structure, reduces the ball's weight and hardness, thus minimizing the inertia generated during throwing and significantly reducing the risk of impact injury to children. Therefore, the grip strength playground ball proposed in this application is particularly suitable for multi-player outdoor or indoor play scenarios compared to conventional balls.

[0048] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
