Description

Technical Field

[0001] The invention belongs to the field of sports equipment, and in particular relates to a foldable football. Background Art

[0002] Traditional footballs use an integrated structural design, which ensures the stability and durability of the football in normal use. However, once a part of the football is damaged (such as a cracked outer shell or damaged liner), it is extremely difficult to repair and the maintenance cost is extremely high. After the football is damaged, it can only be discarded as a whole, which places an unnecessary burden on the environment. Furthermore, the integrated structure of the football takes up a large space when not in use, which is not very convenient for people who need to carry the football frequently. In addition, during long-distance transportation, the integrated football also takes up a lot of space, increasing logistics costs.

[0003] In order to solve the above problems, Japan's Nenbo Design Studio launched an innovative foldable football. The football is made of three parts: the frame, the base and the shell, which are spliced ​​together to achieve a detachable and foldable setting. Although this design brings many conveniences, there are still some problems in actual use:

[0004] First, there is the problem of surface holes. When the football is assembled, there are holes on the surface, which makes it impossible to completely isolate the inside and outside of the football. During use, foreign matter such as sand and dust can easily enter the inside of the football, which not only affects the support experience of the football, but may also cause damage to the internal structure, such as wear or contamination of the connection structure. These holes may also affect the waterproof performance of the football, causing rainwater or other liquids to penetrate, affecting the weight and flight characteristics of the football.

[0005] Secondly, there is the problem of loose connections; the skeleton of the football is connected by a plug-in structure to achieve a detachable design. As the number of uses increases, these plug-in parts may gradually become loose. The loose connection parts will cause the overall stability and shape retention of the football to decrease, affecting its flight trajectory and ball control. This problem is particularly obvious after long-term use, and it may be necessary to regularly check and adjust the tightness of the connection to ensure that the football remains in good condition.

[0006] Finally, there is the issue of assembly complexity. Due to its detachable design, the assembly process of the football requires that individual parts be assembled into a skeleton first, and the assembly level is relatively complicated. For children or non-professionals, correctly assembling the football may require a certain amount of time and skills. Summary of the invention

[0007] In view of this, an object of the present invention is to provide a foldable football to solve the problems existing in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the technical solution of the present invention is a foldable football, including an outer shell, which is used to form the outer contour of the ball; the outer shell includes a first outer shell and a second outer shell; a connecting frame, which is used to assemble the first outer shell and the second outer shell; the connecting frame includes a frame and a clamping rod, the contour of the frame is similar to the contour of the first outer shell, and the clamping rods are arranged in pairs and movably arranged at the corners of the frame; the first outer shell is arranged on the inner side of the frame, and the first outer shell and the frame are buckled; the second outer shell is arranged around the outer side of the frame, and the second outer shell is limited and fixed by the frame and the clamping rod.

[0012] Furthermore, the clamping rod has a fixing surface, which is elastically arranged and matched with the first guide surface.

[0013] Furthermore, an installation groove is opened at the bending corner of the frame, and a clamping block is slidably arranged in the installation groove, and the clamping block acts between the first clamping rod and the second clamping rod at the same bending corner; when the first clamping rod and the second clamping rod at the same bending corner are in contact, the first clamping rod and the second clamping rod are in a parallel state, and the clamping block slides out and acts between the first clamping rod and the second clamping rod, thereby limiting the movement of the first clamping rod and the second clamping rod.

[0016] Furthermore, the mounting groove is provided with a bayonet connected to the bottom end of the frame, and the card block is provided with a control protrusion; when the card block slides out and acts between the first clamp rod and the second clamp rod, the control protrusion is located in the bayonet; the control protrusion is moved out of the bayonet to realize the retraction of the card block and to push the limit protrusion out of the card hole; the outer side of the opening of the card hole is provided with a third guide surface; when the first shell and the frame are fastened together, under the action of the third guide surface, the limit protrusion can be moved to the card hole by pressing the first shell; when the limit protrusion is pushed out of the card hole, under the action of the third guide surface, the first shell and the frame are separated.

[0018] The technical effects of the present invention are mainly reflected in the following aspects:

[0019] Through the improved design of the clamp rod and guide surface, the number of surface holes is reduced, the sealing and waterproof performance of the football is improved, and foreign objects such as sand and dust are prevented from entering the interior of the football, while the possibility of moisture penetration is also reduced; the addition of the card block ensures the stability of the clamp rod during use, reduces the looseness of the connection part, and improves the overall stability and durability of the football.

[0020] The detachable and foldable design allows the football to be easily disassembled and folded for storage when not in use, saving storage space and making it easy to carry; the adjustment block design on the control shell allows the user to easily control the movement of the limit protrusion to separate the first shell from the frame. The modular design allows different parts of the football to be replaced separately, reducing the overall maintenance cost and also reducing the situation where the entire football has to be discarded due to partial damage.

[0034] Embodiment 1

[0035] See also Figure 1 , 5 A foldable football comprises an outer shell, which is used to form the outer contour of the ball; the outer shell comprises a first outer shell 1 and a second outer shell 2; a connecting frame 3, which is used to assemble the first outer shell 1 and the second outer shell 2; the connecting frame 3 comprises a frame 30 and a clamping rod 31, the contour of the frame 30 is similar to that of the first outer shell 1, and the clamping rod 31 is arranged in pairs and movably arranged at the corner of the frame 30; the first outer shell 1 is arranged on the inner side of the frame 30, and the first outer shell 1 and the frame 30 are buckled together; the second outer shell 2 is arranged around the outer side of the frame 30, and the second outer shell 2 is limited and fixed by the frame 30 and the clamping rod 31.

[0036] Specifically, the frame 30 and the clamping rod 31 allow the first shell 1 and the second shell 2 to fit tightly together, reducing the generation of holes; the design of the clamping rod 31 not only limits the position of the second shell 2, but also acts as a seal to prevent foreign matter from entering. The first shell 1 and the second shell 2 can be quickly assembled and disassembled through the cooperation of the frame 30 and the clamping rod 31 without the need for additional tools; the movable design of the clamping rod 31 allows the user to easily install and remove the shells, even children can do it easily. The foldable football solves the problem that traditional footballs are difficult to carry and store, reduces the number of holes, improves the waterproofness and durability of the football, improves the stability of the connection parts, and ensures the accuracy of the shape and flight trajectory of the football.

[0037] See also Figure 4 , 5 The frame 30 is provided with a limiting groove 32, and limiting rods 33 are slidably arranged at both ends of the limiting groove 32, and the limiting rods 33 can control the rotation of the clamping rod 31; the second shell 2 includes a second panel 21 and a clamping strip 22, and the clamping strip 22 is arranged on the periphery of the second panel 21, and the clamping strip 22 is arranged at the bottom end of the second panel 21, and both ends of the clamping strip 22 are provided with a first guide surface 23, and the first guide surface 23 helps to guide the clamping strip 22 to be smoothly inserted into the limiting groove 32 of the frame 30; during the assembly process, the clamping strip 22 is inserted into the limiting groove 32, and under the action of the first guide surface 23, the limiting rod 33 will first move to the corner of the frame 30 and then reset; so as to control the clamping rod 31 at the same corner to separate first and then approach, so as to realize the limiting fixation of the second shell 2.

[0038] Specifically, a clamping strip 22 is arranged around the second panel 21 of the second shell 2, and first guide surfaces 23 are arranged at both ends of the clamping strip 22, which help guide the clamping strip 22 to be smoothly inserted into the limiting groove 32 of the frame 30. Assembly process: the first shell 1 is placed on the inner side of the frame 30 and is engaged with the frame 30; the clamping strip 22 of the second shell 2 is inserted along the limiting groove 32 of the frame 30, at which time, the first guide surface 23 of the clamping strip 22 will push the limiting rod 33 to move toward the corner of the frame 30. When the clamping strip 22 is fully inserted into the limiting groove 32, the limiting rod 33 will be reset under the action of the spring, driving the clamping rod 31 from the separated state to the close state, thereby fixing the second shell 2 on the frame 30. The problem that traditional footballs are difficult to carry and store is solved; through the design of the limiting groove 32 and the limiting rod 33, the fixing problem of the second shell 2 is effectively solved, and the waterproofness and durability of the football are improved; the stability of the connection part is improved, and the accuracy of the shape and flight trajectory of the football is guaranteed.

[0039] See also Figure 6, a second guide surface 34 is provided at the corner of the frame, the clamp rod 31 is in contact with the second guide surface 34, and the second guide surface 34 can control the up and down movement of the clamp rod 31; under the action of the first guide surface 23, the clamp rod 31 at the same corner will move toward the bottom end of the frame when separated; the clamp rod 31 at the same corner will move toward the top end of the frame when approaching. The second guide surface 34 guides the moving direction of the clamp rod 31, ensuring that the clamp rod 31 can move along a predetermined path when driven by the first guide surface 23. Under the action of the second guide surface 34, the clamp rod 31 at the same corner will move toward the bottom end of the frame 30 when separated, and will move toward the top end of the frame 30 when approaching, thereby ensuring that the clamp rod 31 can separate or approach at the right time. The clamp rod 31 has a fixing surface, which is elastically arranged and adapted to the first guide surface 23.

[0040] Specifically, when the clamping strip 22 of the second housing 2 is inserted into the limiting groove 32 of the frame 30, the first guide surface 23 will prompt the limiting rod 33 to move toward the bend of the frame 30. In this process, the limiting rod 33 will first push the clamping rod 31 to separate, so that the clamping strip 22 can smoothly pass through the limiting groove 32. When the clamping strip 22 completely enters the limiting groove 32, the limiting rod 33 will automatically reset, and the clamping rod 31 will move toward the top of the frame 30 under the guidance of the second guide surface 34, thereby tightly clamping the clamping strip 22 and completing the fixation of the second housing 2. Conversely, if the second housing 2 is to be disassembled, it is only necessary to reverse the process. For example, by manually operating the limiting rod 33 to move toward the bend of the frame 30 again, the clamping rod 31 will move toward the bottom of the frame 30 along the second guide surface 34, releasing the clamping strip 22, so that the second housing 2 can be easily removed from the frame 30.

[0041] Embodiment 2

[0042] This embodiment discloses a foldable football. Compared with the football in the first embodiment, this embodiment further defines the clamping rod 31. The specific conditions are as follows:

[0043] See also Figure 7, the clamping rod 31 at the same bend is divided into a first clamping rod 35 and a second clamping rod 36, the first clamping rod 35 and the second clamping rod 36 are distributed on the frame 30 in a circular array; the end of the first clamping rod 35 is rotatably provided with a connecting piece 37, and the end of the second clamping rod 36 is provided with a connecting groove 38, and the connecting piece 37 and the connecting groove 38 are adapted; the second housing 2 is fixed by two oppositely arranged connecting frames 3, wherein the clamping rod 31 on the other connecting frame 3 is divided into a third clamping rod 39 and a fourth clamping rod 40; when When the first clamp rod 35 and the second clamp rod 36 are fitted together and the third clamp rod 39 and the fourth clamp rod 40 are fitted together, the first clamp rod 35 and the fourth clamp rod 40 as well as the second clamp rod 36 and the third clamp rod 39 are all arranged in an arc shape, and the arc is parallel to the clamping strip 22; the connecting piece 37 on the first clamp rod 35 is rotated into the connecting groove 38 of the fourth clamp rod 40, and the connecting piece 37 on the third clamp rod 39 is rotated into the connecting groove 38 of the second clamp rod 36, so as to realize the connection and fixation of the two relatively arranged connecting frames 3.

[0044] Specifically, when the second shell 2 is placed on the frame 30, the clamping strip 22 is inserted into the limiting groove 32, and the clamping rod 31 is separated or fitted according to the action of the guide surface to fix the position of the second shell 2. At this time, the first clamping rod 35 and the second clamping rod 36, the third clamping rod 39 and the fourth clamping rod 40 are respectively fitted and form a stable arc structure to ensure that the second shell 2 will not loosen. Next, in order to achieve the fixation between the two connecting frames 3, the operator needs to rotate the connecting piece 37 on the first clamping rod 35 and insert it into the connecting groove 38 of the fourth clamping rod 40, and at the same time rotate the connecting piece 37 on the third clamping rod 39 and insert it into the connecting groove 38 of the second clamping rod 36. In this way, through a simple rotation operation, the two relatively arranged connecting frames 3 can be firmly connected together, thereby completing the assembly of the entire football.

[0045] See also Figure 8 A mounting groove 42 is provided at the corner of the frame 30, and a clamping block 43 is slidably arranged in the mounting groove 42, and the clamping block 43 acts between the first clamping rod 35 and the second clamping rod 36 at the same corner; when the first clamping rod 35 and the second clamping rod 36 at the same corner are in contact, the first clamping rod 35 and the second clamping rod 36 are in a parallel state, and the clamping block 43 slides out and acts between the first clamping rod 35 and the second clamping rod 36, restricting the movement of the first clamping rod 35 and the second clamping rod 36, and preventing the first clamping rod 35 and the second clamping rod 36 from accidentally separating when there is no external force.

[0046] Specifically, when the first clamping rod 35 and the second clamping rod 36 are in contact, they are in a parallel state; to ensure that the second shell 2 can be stably fixed on the frame 30, at this time, the block 43 slides out of the mounting groove 42; the block 43 acts between the first clamping rod 35 and the second clamping rod 36 to prevent them from separating in an uncontrolled manner; the stability of the clamping rod 31 when fixing the second shell 2 is ensured, and problems caused by the loosening of the clamping rod 31 during use are avoided.

[0047] Embodiment 3

[0048] This embodiment discloses a foldable football. Compared with the football in the first embodiment, this embodiment further limits the fixing method of the first shell 1. The specific situation is as follows:

[0049] See also Figure 2 , 9 A card hole 44 is provided at the corner of the frame 30; the first shell 1 is composed of a first panel 11 and a limiting protrusion 12 arranged at the bottom end of the first panel 11; the limiting protrusion 12 is built into the card hole 44 to achieve the buckling of the first shell 1 and the frame 30.

[0050] See also Figure 8 , 9 The locking hole 44 is connected to the mounting groove 42, and the sliding of the locking block 43 is controlled by the limiting protrusion 12; when the limiting protrusion 12 is located in the locking hole 44, the limiting protrusion 12 pushes the locking block 43, allowing the locking block 43 to act between the first clamping rod 35 and the second clamping rod 36, thereby limiting the movement of the first clamping rod 35 and the second clamping rod 36.

[0051] See also Fig. 9The mounting groove 42 is provided with a bayonet 45 connected to the bottom end of the frame 30, and the block 43 is provided with a control protrusion 46; when the block 43 slides out and acts between the first clamping rod 35 and the second clamping rod 36, the control protrusion 46 is located in the bayonet 45; the control protrusion 46 is moved out of the bayonet 45 to realize the retreat of the block 43 and the ejection of the limiting protrusion 12 from the clamping hole 44; the outer side of the opening of the clamping hole 44 is provided with a third guide surface 47; when the first shell 1 and the frame 30 are fastened together, under the action of the third guide surface 47, the limiting protrusion 12 can be moved into the clamping hole 44 by pressing the first shell 1; the fastening process: when the first shell 1 is fastened with the frame 30, the limiting protrusion 12 enters the clamping hole 44; the limiting protrusion 12 pushes the block 43 to slide out of the mounting groove 42; the block 43 is fastened between the first clamping rod 35 and the second clamping rod 36 to restrict their movement. When the limiting protrusion 12 is pushed out from the clamping hole 44, under the action of the third guide surface 47, the first shell 1 and the frame 30 are separated; separation process: when the first shell 1 and the frame 30 need to be separated, the control protrusion 46 is moved to be moved out of the clamping hole 45, so that the clamping block 43 can retreat from between the first clamping rod 35 and the second clamping rod 36; when the clamping block 43 retreats, the limiting protrusion 12 is no longer subjected to the pressure of the clamping block 43, and the limiting protrusion 12 can be pushed out from the clamping hole 44.

[0052] Specifically, by providing a clamping hole 44 at the corner of the frame 30 and providing a limiting protrusion 12 at the bottom end of the first panel 11 of the first shell 1, a stable buckle between the first shell 1 and the frame 30 can be achieved. At the same time, the limiting protrusion 12 interacts with the clamping block 43 in the installation groove 42 to limit the movement of the first clamping rod 35 and the second clamping rod 36, thereby ensuring the stable fixation of the second shell 2; this not only improves the durability and stability of the football, but also simplifies the assembly process, and the buckle and separation between the first shell 1 and the frame 30 can be achieved through simple operations.

[0053] See also Figure 2 , 3The first housing 1 is divided into a fixed housing 13 and a control housing 14, and the housing includes at least one control housing 14; the first panel 11 and the limiting protrusion 12 are fixedly connected to form the fixed housing 13, and the fixed housing 13 provides a basic structure to ensure the stable connection between the first housing 1 and the frame 30. The first panel 11 and the limiting protrusion 12 are slidably connected to form the control housing 14, and the control housing 14 also includes an adjustment block, which is slidably set on the top of the first panel 11, and the adjustment block is connected to the limiting protrusion 12; the limiting protrusion 12 is controlled to move by the control block 15, and the limiting protrusion 12 is moved out of the clamping hole 44 to achieve the separation of the first housing 1 and the frame 30.

[0054] Specifically, the first shell 1 is divided into a fixed shell 13 and a control shell 14; wherein, the fixed shell 13 ensures basic structural stability and connection strength, and can only be separated from the inside of the football by moving the control protrusion 46 out of the bayonet 45; and the control shell 14 provides a convenient separation mechanism through the adjustment block, so that the football can be separated from the control shell 14 through the adjustment block, thereby opening the interior of the football, allowing the user to achieve the overall separation of the football components more quickly.

[0055] The technical effects of the present invention are mainly reflected in the following aspects:

[0056] Through the improved design of the clamp rod 31 and the guide surface, the number of surface holes is reduced, the sealing and waterproof performance of the football is improved, and foreign objects such as sand and dust are prevented from entering the interior of the football, while the possibility of moisture penetration is also reduced; the addition of the clamp block 43 ensures the stability of the clamp rod 31 during use, reduces the looseness of the connection part, and improves the overall stability and durability of the football.

[0057] The detachable and foldable design allows the football to be easily disassembled and folded for storage when not in use, saving storage space and making it easy to carry; the adjustment block design on the control shell 14 allows the user to easily control the movement of the limit protrusion 12 to separate the first shell 1 from the frame 30. The modular design allows different parts of the football to be replaced separately, reducing the overall maintenance cost and also reducing the situation where the entire football has to be discarded due to partial damage.

[0058] In addition, as common knowledge in the industry, the control block 15, the clamping rod 31 and the clamping block 43 mentioned above are provided with corresponding return springs and the material of the parts of the football. The above is common knowledge, so its principle and structure will not be described in detail.

[0059] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
