Description

Technical Field

[0001] This invention belongs to the field of billiard table technology, specifically relating to an integrated cushion for a billiard table. Background Technology

[0002] A typical billiard table consists of a tabletop, cushions, and multiple legs. The legs support the bottom of the tabletop, while the cushions are fixed around the perimeter of the tabletop to form the cushion structure for the balls to strike. The tabletop is made of slate and cloth laid on top of the slate.

[0003] like Figure 1 As shown, an existing table edge includes a rubber strip I2, a steel plate 4, a lower wooden strip I10, a backing wooden strip 11, and a wooden handrail 5. The backing wooden strip 11 is fixedly connected to the inner side of the steel plate 4 by screws 12, and the wooden handrail 5 is fixedly connected to the outer side of the steel plate 4 by handrail screws 6. The steel plate 4 is fixedly installed on the side of the stone slab 7 on the tabletop by bolts 9 and nuts 8, forming a single unit. The inner perimeter of the table edge is also covered with tablecloth 1, one end of which is pressed into a groove on the outer side of the steel plate 4 by a tablecloth pressing strip 3, and the other end is pressed between the stone slab 7 and the backing wooden strip 11. In the above-mentioned table edge, the steel plate 4, the lower wooden strip I10, the backing wooden strip 11, and the wooden handrail 5 constitute the main structure of the table edge.

[0004] The existing table cushions (hereinafter referred to as "steel cushions") mainly have the following problems: First, in the production process of steel cushions, not only do the steel plates 4, the lower wooden strips I 10, the back wooden strips 11, and the wooden handrails 5 need to be produced separately, but they also need to be assembled. This consumes a lot of manpower, material resources, and time, resulting in high production costs, long cycles, and low assembly efficiency. Second, because the existing steel cushions are composite structures of steel plates and wooden boards, and the Young's modulus of elasticity of the wooden boards is much smaller than that of the steel plates, the stress in the steel cushion structure is concentrated in the steel plate area. The stress distribution is uneven, which causes players to have different hitting sensations when hitting the billiard ball from different angles and with different forces. This increases the uncertainty of the shot and affects the player's judgment of the ball's trajectory. Third, the rebound kinetic energy loss rate and rebound accuracy are important indicators for evaluating cushion performance. Under the same working conditions, the smaller the rebound kinetic energy loss rate, the better the cushion performance; the higher the rebound accuracy, the better the cushion performance. Based on the above two standards and combined with the performance of the steel silo under different working conditions, the overall performance of the steel silo was comprehensively evaluated. The evaluation result was low, so the overall performance of the steel silo was poor. Summary of the Invention

[0005] In view of this, the present invention provides an integrated cushion for a billiard table, which not only has the advantages of simple structure, short production cycle, saving manpower and material resources and reducing assembly workload, but also has the advantages of uniform stress distribution, low rebound kinetic energy loss rate and high rebound accuracy, which can improve the certainty of the ball's trajectory after hitting the cushion.

[0067] Furthermore, the total width of the integrated storage edge is 12cm-16cm, and the total height is 9cm-13cm.

[0068] Beneficial effects:

[0069] (1) This invention includes an integrally formed block A, block B, and block C. First, the integrated cushion is an integral structure, and the same material is used throughout the cushion. Since the stress generated by the ball can be diffused throughout the entire cushion, the stress distribution is uniform, so that players have the same feeling when hitting the ball with various angles and forces, which can reduce the uncertainty of the shot and enhance the competitive experience of the game. Second, compared with the traditional steel cushion, the production process does not require the separate production of steel plates and backing wood strips, eliminating the separate processing and positioning assembly procedures for steel plates and backing wood strips, reducing manufacturing steps and improving assembly efficiency;

[0070] (2) The outer end of block A of the present invention can extend horizontally to the top of block C as a handrail, and the handrail is also processed as an integral part, eliminating the separate processing and positioning assembly process of the handrail, reducing the manufacturing process and improving the assembly efficiency.

[0071] Furthermore, compared to setting only the CI block, the integrated handrail allows for a wider range of stress diffusion and a more uniform stress distribution during ball impact. This further enables players to have the same hitting feel when hitting the billiard ball at various angles and with varying force, reducing uncertainty during the shot and enhancing the competitive gaming experience.

[0072] (3) The material of the integrated cushion edge of the present invention can be aluminum alloy. Since the stress distribution of the integrated cushion edge is more uniform than that of the steel cushion when the ball is hit, the maximum stress in the integrated cushion edge is less than that in the steel cushion under the same working conditions. Therefore, aluminum alloy with a smaller elastic modulus can be selected. This can ensure that the strain of the integrated steel cushion meets the requirements under different working conditions. In addition, aluminum alloy has the advantages of low density, light weight, easy processing, high strength, high toughness and good corrosion resistance, which can reduce the weight of the cushion edge and extend the service life of the cushion edge.

[0073] Furthermore, according to simulation analysis results, under the premise of consistent collision speed and incident angle, the integrated aluminum alloy cushion is superior to the steel cushion in terms of both rebound kinetic energy loss rate and rebound accuracy. When comprehensively evaluating all collision conditions, the integrated cushion scores higher than the steel cushion. Therefore, the integrated cushion has better rebound performance, reduces the uncertainty of the trajectory of the billiard ball after hitting the cushion, and improves the gaming experience.

[0074] (4) The bottom surface of the B block of the present invention is provided with a bottom groove along the length direction. The bottom groove can cooperate with the pressure block to hide the bottom end of the table cloth and make the table cloth flat, thus maintaining the aesthetics of the billiard table.

[0075] (5) The A block of the present invention is provided with a top groove along the length direction. The top groove can cooperate with the pressure strip to hide the top of the table cloth and make the table cloth flat, thus maintaining the aesthetics of the billiard table.

[0076] (6) This invention limits the minimum area of ​​the XY section of the CⅠ block. According to this formula, the minimum area of ​​the XY section can be obtained based on the stress generated in the X direction of the CI block after the external force is applied to the CI block. When the Y direction length of the CI block is constant, the minimum thickness of the CI block in the X direction can be calculated, thereby maximizing the saving of processing materials while meeting the strength requirements.

[0077] (7) The present invention limits the mass M of the portion of block A located inside the vertical dividing plane II. A1 The mass of block A, located on the outer side of vertical dividing plane II, is M. A2 The quality of block B, M B The mass of block CⅠ is M CⅠ And the quality M of block CⅡ CⅡ Satisfying the formula: MA1 +M B +M CⅠ ≥M A2 +M CⅡ The center of gravity of the integrated warehouse edge is located on or inside the CI block, which reduces the impact of the torque generated by the weight of the CI block on the stability of the warehouse edge, thus ensuring the stability and durability of the warehouse edge in use; at the same time, it can achieve the purpose of saving labor in assembly.

[0078] (8) In this invention, block A extends horizontally outward from the top surface of block B to the vertical dividing surface II, which can provide the necessary conditions for maximizing the strength of block CⅡ.

[0079] (9) In this invention, the vertical dividing surface between block B and block CⅠ is vertical dividing surface Ⅰ. Block A extends horizontally outward along the top surface of block B to vertical dividing surface Ⅰ, so that the outer end face of block A is vertically flush with the outer side of the table, which is aesthetically pleasing.

[0080] (10) The CⅡ block of the present invention can be a top support plate, the inner side of the top support plate is integrally formed with the CⅠ block and extends in the horizontal direction to support the handrail installed thereon; thus facilitating the installation of the handrail.

[0081] In addition, the top support plate is integrally formed on the outer side of the CI block. Compared with setting only the CI block, it can make the stress diffusion range of the ball collision larger and the stress distribution more uniform. This further enables players to have the same hitting feel when hitting the billiard ball at various angles and with various forces, which can reduce the uncertainty of the shot and enhance the competitive experience of the game.

[0082] (11) The CⅡ block of the present invention may include a top support plate and a bottom support plate. While improving the elasticity of the billiard table, the top support plate can support the handrails on it. A decorative plate may be set between the top support plate and the bottom support plate, so that the outer periphery structure of the billiard table is simple and the overall aesthetics of the billiard table are improved.

[0083] In addition, the top support plate and the bottom support plate are integrally formed on the outer side of the CI block. Compared with setting only the CI block, the stress generated during the collision of the ball can spread over a larger range and the stress distribution is more uniform. This further enables players to have the same feeling when hitting the billiard ball at various angles and with various forces, which can reduce the uncertainty of the shot and enhance the competitive experience of the game.

[0084] (12) The outer end of block A of this invention can extend horizontally outward along the top surface of block B to the top of block C as an integrally formed handrail, and block C only includes block CI; the width of the handrail is greater than the width of block CI. According to formula 1, when the mass M of block CI is... CⅡWhen the mass M is zero, it ensures that block A is located on the outer side of the vertical dividing plane II. A2 Therefore, when the width of block A in the X direction and the length in the Y direction are constant, the thickness of block A in the Z direction is the greatest, and the strength is the greatest.

[0085] (13) The outer end of block A of the present invention can extend horizontally outward along the top surface of block B as an integrally formed handrail, and block C includes block CⅠ and block CⅡ, block CⅡ being a bottom support plate, the inner side of the bottom support plate being integrally formed with block CⅠ, the bottom support plate being spaced below block A and parallel to block A. A decorative plate can be set between block A and the bottom support plate to make the outer perimeter structure of the billiard table simple and improve the overall aesthetics of the billiard table.

[0086] Furthermore, the integrated handrail and CⅡ block design, compared to only having a CⅠ block, allows for a wider range of stress diffusion and a more uniform stress distribution during ball impact. This further enables players to have the same hitting feel when hitting the billiard ball at various angles and with varying force, reducing uncertainty during the shot and enhancing the competitive gaming experience.

[0087] (14) The inner side of block B of the present invention is integrally formed with a protruding structure for supporting the adhesive strip. The present invention also integrates the protruding structure of the adhesive strip, further reducing the manufacturing process and improving the assembly efficiency.

[0088] (15) The protruding structure of the present invention is a rubber strip support strip extending along the length direction of the cushion; the height H of the top surface of the rubber strip support strip from the table surface is (R(1+sinθ)-Z1), where θ is the angle between the line OJ connecting the center O and the impact point J and the table surface, and the impact point J is higher than the center O of the billiard ball in the vertical direction; the height H of the top surface of the rubber strip support strip from the table surface of the present invention is related to the angle θ, so that the impact force generated by the billiard ball when it hits the rubber strip forms a downward component force, preventing the billiard ball from jumping upward, thereby avoiding the phenomenon of the billiard ball jumping when it hits the rubber strip and improving the hitting experience.

Detailed Implementation

[0106] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0107] Example 1:

[0108] This embodiment provides an integrated cushion for a billiard table, see attached document. Figure 2 It includes the integrally formed A block, B block and C block;

[0109] For ease of description, let the length direction of the integrated warehouse be the Y direction, the height direction be the Z direction, and the width direction be the X direction.

[0110] The edge of the integrated warehouse edge table is set with block B located inside block C; and the bottom height of block B is greater than the bottom height of block C, so the bottom surface of block B and the inner side of block C are connected to form a mounting surface for mating with the edge of the table; the top surface of block C and the top surface of block B are both horizontal and at the same height (i.e., they are in the same horizontal plane).

[0111] A bottom groove 101 is provided on the bottom surface of block B along the length direction for pressing the bottom end of the pad fabric;

[0112] Block A is located on top of Block B. The outer end of Block A extends horizontally outward. A top groove 102 is provided on Block A along its length for pressing the top of the mat.

[0113] A handrail is provided at the top of Block C. The handrail can be a fixedly connected handrail or a one-piece molded handrail.

[0114] The aforementioned integrated cushion adopts a one-piece molded structure. First, the integrated cushion is a single-piece structure, using the same material throughout. Because the stress generated by the shot can be diffused throughout the entire cushion, the stress distribution is uniform. This allows players to experience the same hitting feel when striking the ball from various angles and with varying force, reducing uncertainty during the shot and enhancing the competitive experience. Second, the production process eliminates the need for separate production of steel plates and backing wood strips, reducing the need for separate processing and assembly procedures for these components, thus decreasing manufacturing steps and improving assembly efficiency.

[0115] The integrated warehouse edge can be made entirely of metal or non-metal materials. Metal materials can be aluminum alloys; non-metal materials can be carbon fiber or fiberglass.

[0116] In a specific embodiment, the integrated cushion edge is made of aluminum alloy. Because the stress distribution of the integrated cushion edge is more uniform than that of the steel cushion during ball impact, the maximum stress in the integrated cushion edge is less than that in the steel cushion under the same working conditions. Therefore, aluminum alloy with a smaller elastic modulus can be selected. This ensures that the strain of the integrated steel cushion meets the requirements under different working conditions. In addition, aluminum alloy has the advantages of low density, light weight, easy processing, high strength, high toughness, and good corrosion resistance, which can reduce the weight of the cushion edge and extend its service life.

[0117] Furthermore, simulation analyses were conducted on an integrated cushion edge made of aluminum alloy and a steel cushion. The results showed that, under the premise of consistent collision speed and incident angle, the integrated cushion edge was superior to the steel cushion in both rebound kinetic energy loss rate and rebound accuracy. When the weights of rebound kinetic energy loss rate and rebound accuracy were both 0.5, the integrated cushion edge scored higher than the steel cushion when comprehensively evaluating all collision conditions, indicating that the integrated cushion edge made of aluminum alloy had better rebound performance.

[0118] Example 2:

[0119] This embodiment, based on Embodiment 1, provides an integrated cushion for a billiard table. (See attached document.) Figure 4-5 The C block is divided into two parts from the inside out by the vertical dividing surface II. The part located inside the vertical dividing surface II is called the CI block, and the part located outside the vertical dividing surface II is called the CI block. The inner side of the CI block is integrally formed with the B block, and the CI block is integrally formed on the outer side of the CI block.

[0120] By setting up the CⅡ block, compared to not setting up the CⅡ block, the stress diffusion range generated during the ball collision is larger and the stress distribution is more uniform. This further enables players to have the same hitting feel when hitting the billiard ball at various angles and with various forces, reducing the uncertainty of the shot and enhancing the competitive gaming experience.

[0121] For the minimum area S of the XY section of block CⅠ min The following formula must be satisfied:

[0122]

[0123] When an external force is applied to block CⅠ, the stress F in the X direction generated within block CⅠ is influenced by various horizontal forces applied to block CⅠ, such as the ball's velocity upon impact with the cushion, the weight of block CⅡ, and the vertical force exerted by the player on the handrail. s The yield strength of the integrated warehouse edge material.

[0124] The maximum stress Fmax in the X direction that can be generated in block C1 can be calculated based on the horizontal forces applied to block C1, such as the maximum ball speed when the ball hits the edge of the cushion (the maximum ball speed when the ball hits the edge of the cushion is an empirical value, and 30m / s is used in the actual simulation calculation), the actual weight of block C2, and the maximum vertical force exerted by the player on block C2 (the maximum vertical force exerted by the player on the handrail is a set value, which can be set according to actual needs). According to formula (2), when the length of block C1 in the Y direction is constant, the minimum thickness X in the X direction of block C1 can be calculated. CⅠmin , that is, X CⅠ ≥X CⅠmin This allows for maximum material savings during processing while meeting strength requirements. In a specific embodiment, the Y-direction length of the CⅠ block is 1260 mm, and the yield strength of the aluminum alloy is 265 MPa.

[0125] Example 3:

[0126] This embodiment, based on embodiment 2, provides an integrated cushion for a billiard table, wherein the mass of the portion of block A located inside the vertical dividing plane II is M. A1 The mass of block A located outside the vertical dividing plane II is M. A2 The mass of block B is M. B The mass of block CⅠ is M CⅠ The mass of block CⅡ is M CⅡ ;

[0127] M A1 M A2 M B M CⅠ and M CⅡ Satisfying the formula:

[0128] M A1 +M B +M CⅠ ≥M A2 +M CⅡ (1)

[0129] According to formula (1), the center of gravity of the integrated warehouse edge is located on or inside block CⅠ, which reduces the impact of the torque generated by the weight of block CⅡ on the stability of the warehouse edge, so as to ensure the stability and durability of the warehouse edge; at the same time, it can achieve the purpose of saving assembly effort.

[0130] The outer end of block A extends horizontally outward from the top surface of block B to the vertical dividing plane II, providing the necessary condition for maximizing the strength of block CⅡ; the reason is that, according to formula (1), when (M A1 +M B +M CⅠ Given a fixed value for M, in order to ensureCⅡ To reach the maximum, that is, to ensure the thickest thickness in the vertical direction, thus maximizing the support strength for the handrail, there is M. A2 =0, meaning that the outer end of block A extends horizontally outward from the top surface of block B to the vertical dividing surface II.

[0131] In a specific embodiment, the dividing surface between block B and block CI is a vertical dividing surface I. The outer end of block A extends horizontally outward along the top surface of block B to the vertical dividing surface I. That is, the outer end face of block A is vertically flush with the outer side of the table, which is aesthetically pleasing.

[0132] Example 4:

[0133] This embodiment, based on embodiment 2 or 3, provides an integrated cushion for a billiard table, see attached document. Figure 3 The CⅡ block is a top support plate 103 integrally formed on the upper part of the outer surface of the CI block. The inner side of the top support plate 103 is integrally formed with the CI block and extends outward in the horizontal direction, which can be used to support the handrail installed on it; thereby enabling the handrail to be installed above the top support plate 103, which facilitates the installation of the handrail.

[0134] Example 5:

[0135] This embodiment, based on embodiment 2 or 3, provides an integrated cushion for a billiard table, see attached document. Figure 4 Block CⅡ includes a top support plate 103 and a bottom support plate 104 integrally formed with block CⅠ. The bottom support plate 104 is located below the top support plate 103 and is parallel to the top support plate 103. The thickness of the top support plate 103 is greater than the thickness of the bottom support plate 104 (let the height dimension of the support plate be the thickness, i.e., ...). Figure 4 (As shown in the Z direction); A vertical decorative panel is provided between the top support plate 103 and the bottom support plate 104, which makes the outer perimeter structure of the billiard table simple and improves the overall aesthetics of the billiard table. In addition, the top support plate 103 is used for the main load-bearing, so the thickness of the top support plate 103 is greater than the thickness of the bottom support plate 104 to ensure the strength of the top support plate 103.

[0136] Example 6:

[0137] This embodiment, based on embodiment 2 or 3, provides an integrated cushion for a billiard table, see attached document. Figure 5 In one specific embodiment, block C includes only block CⅠ and does not include block CⅡ. A handrail (such as a wooden handrail or other handrail, not shown in the figure) is fixedly connected to the top of block CⅠ.

[0138] The vertical dividing plane I and vertical dividing plane II mentioned above are dividing planes used to divide the area for ease of description; each block is actually formed as a single piece.

[0139] Example 7:

[0140] This embodiment, based on embodiment 1 or 2, provides an integrated cushion for a billiard table, see attached document. Figure 6 In this embodiment, the outer end of block A is directly extended horizontally outward from the top surface of block B to the top of block C to form an integrally formed handrail. At this time, the top groove 102 is located on the top surface of block A, which facilitates the pressing of the tablecloth.

[0141] In this embodiment, the handrail is also processed as a single unit, eliminating the need for separate processing and positioning assembly of the handrail, reducing manufacturing steps, and improving assembly efficiency.

[0142] In one specific embodiment, see Appendix Figure 7 Block C only includes Block CⅠ; the width of the handrail is greater than the width of Block CⅠ (i.e., the dimension of the handrail in the X direction). According to formula (1) of Example 3, when the mass M of Block CⅡ CⅡ When the mass M is zero, it ensures that block A is located on the outer side of the vertical dividing plane II. A2 This maximizes the thickness and strength of block A in the Z direction, so that when the width of block A in the X direction and the length in the Y direction are constant.

[0143] In one specific embodiment, see Appendix Figure 8 Block C includes Block CⅠ and Block CⅡ. Block CⅡ is the bottom support plate 104. The inner side of the bottom support plate 104 is integrally formed with Block CⅠ. The bottom support plate 104 is located below Block A and is parallel to Block A. A vertical decorative plate can be set between the bottom surface of Block A and the bottom support plate 104 to make the outer perimeter structure of the billiard table simple.

[0144] In a specific embodiment, the width of block A (i.e., the dimension along the X direction) is 12-16cm, such as 12cm, 12.5cm, 13cm, 13.5cm, 14cm, 14.5cm, 15cm, 15.5cm, and 16cm.

[0145] Example 8:

[0146] This embodiment, based on embodiments 1-7, provides an integrated cushion for a billiard table. See attached document. Figure 9The inner side of block B has an integrally formed protruding structure as a support structure for the rubber strip. The protruding structure can be a rubber strip support strip 106 extending along the length of the wall edge. Rubber strip II 111 is installed on the rubber strip support strip 106. The integrated rubber strip support strip 106 eliminates the need for separate processing and positioning assembly of the lower lining wood strip, further reducing manufacturing steps and improving assembly efficiency. The cross-section of the rubber strip support strip 106 can be rectangular, L-shaped, or other shapes.

[0147] The formula for calculating the height H of the top surface of the rubber strip support 106 from the table surface is as follows:

[0148] H=R(1+sinθ)-Z1 (3)

[0149] See Appendix Figure 9 Let J be the point of impact between the billiard ball and the rubber strip II111. The point of impact is vertically higher than the center of the billiard ball. R is the radius of the billiard ball. θ is the angle between the line OJ connecting the center O of the billiard ball and the point of impact J and the table surface, and 2°≤θ≤8°. Z1 is the vertical distance from the point of impact J on the rubber strip to the top surface of the rubber strip support strip 106. When the cross-section of the rubber strip II111 is rectangular, Z1=0.

[0150] The height H of the top surface of the rubber strip support 106 from the table surface is greater than the radius of the billiard ball, so that the impact force generated when the billiard ball hits the rubber strip forms a downward component force, preventing the billiard ball from jumping upward, thereby avoiding the phenomenon of the billiard ball jumping when hitting the rubber strip.
