Description

Technical Field

[0001] This utility model relates to a billiard table bracket and a billiard table, belonging to the field of structural design technology. Background Technology

[0002] A pool table is generally composed of a slate tabletop, cushions, and a support frame, with the support frame providing support for the slate tabletop.

[0003] Most billiard table stands on the market today use a frame structure to support the tabletop. This provides a large contact area between the stand and the ground, ensuring the stability of the billiard table during use.

[0004] However, this traditional redundant structural design of the support frame also has some obvious drawbacks. From a cost perspective, a larger frame structure means that more materials are needed to construct the support frame, and the number of processing steps also increases, significantly raising the overall production cost of the billiard table. From a transportation perspective, the larger support structure increases the weight of the billiard table, increasing transportation costs and difficulties during transport.

[0005] Given the high cost and inconvenient transportation of traditional billiard table support designs, it is necessary to redesign the billiard table support structure. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example 1: This embodiment provides a billiard table support, which includes a bottom support frame 1 and a top support frame 2. The upper end of the bottom support frame 1 is connected to the top support frame 2 (fixed or detachable connection), and the lower end is supported on the ground. The top support frame 2 supports the panel assembly through a support part. The panel assembly includes a slate tabletop 401 and cushions 402 disposed around the slate tabletop. The support part contacts the slate tabletop 401 in the panel assembly to provide support.

[0031] As an example, the top support frame 2 is supported by several leveling bolts 3 on its surface, which serve as support for the panel assembly. Figure 1 As shown, two rows ("row" refers to the length of the billiard table) are arranged parallel to each other on the surface of the top support frame 2, with multiple leveling bolts 3 in each row serving as support parts to support the panel assembly; the leveling bolts 3 in the two rows correspond one-to-one in position (i.e., symmetrical about the longitudinal center line I along the slate tabletop 401). Preferably, the leveling bolts 3 in each row are evenly spaced along the length of the billiard table.

[0032] As an example, the top support frame 2 includes two parallel longitudinal support beams, symmetrically arranged along the longitudinal centerline I of the stone tabletop. Each support beam has several leveling bolts 3 evenly spaced longitudinally as support components. Let the length of the support beam be L2, and the length of the stone tabletop 401 be L1. The ratio of L2 to L1 (i.e., L2:L1) is not less than 0.85; preferably 0.85 to 0.95. The distance d between the leveling bolts 3 at both ends of each support beam and the corresponding end face of the support beam is the same, preferably 80mm to 90mm.

[0033] Let the area of ​​the billiard table slate 401 be A1, the supporting area of ​​the top support frame 2 on the slate slate 401 be A2, and the supporting area of ​​the bottom support frame 1 on the ground be A3.

[0034] This can be understood as follows: the supporting area of ​​the top support frame 2 on the stone slab tabletop 401 is the projected area of ​​the supporting part of the top support frame 2 on the stone slab tabletop 401 (i.e., the area enclosed by the outer contour line of the supporting part); for example, when the top support frame 2 supports the stone slab tabletop 401 through two rows of leveling bolts 3, the supporting area of ​​the top support frame 2 on the stone slab tabletop 401 is the area of ​​the rectangle formed by connecting the two rows of leveling bolts 3 end to end. Figure 1 A2 in the diagram. The supporting area of ​​the bottom support frame 1 on the ground is the projected area of ​​the bottom support frame 1 on the ground (the area enclosed by the outer contour of the shadow).

[0035] For a standard billiard table, its height (the height of a standard billiard table is 0.76m) and the area A1 of the slate tabletop 401 are fixed values. Under the premise that the height of the billiard table and the area A1 of the slate tabletop 401 are fixed, the ratio of A2 to A1 (i.e., A2:A1) is not less than 0.6; preferably, the range of A2:A1 is 0.6 to 0.8; the ratio of A3 to A1 (i.e., A3:A1) is not less than 0.3; preferably, the range of A3:A1 is 0.4 to 0.6.

[0036] Preferably, the centroid of the slate tabletop 401, the centroid of the top support frame 2, and the centroid of the bottom support frame 1 are on the same straight line.

[0037] With the height of the billiard table and the area A1 of the slate table 401 fixed, by optimizing the ratio of the support area of ​​the top support frame 2 to the slate table surface area to the billiard table surface area, and the ratio of the support area of ​​the bottom support frame 1 to the ground area to the billiard table surface area, the stability of the billiard table can be guaranteed when designing the size of the billiard table support, as long as these ratio conditions are met, thus avoiding the use of a large and redundant support.

[0038] Example 2: In this example, the length of the stone tabletop 401 is 2.64m and the width is 1.36m, therefore A1 = 3.5904m. 2 ; like Figure 1 As shown, the top support frame 2 includes two parallel support beams. Each support beam has a number of leveling bolts 3 evenly spaced as support sections. The area enclosed by the leveling bolts 3 is A2 = 2.25m². 2 That is, A2:A1≈0.63.

[0039] like Figure 2 As shown, the bottom support frame 1 includes two bottom beams arranged in a figure-eight pattern on the left and right sides (i.e., the horizontal axis of the billiard table). The two bottom beams are supported on the ground. The length of the bottom beams is 1.88m, the distance between the front ends is 0.24m, and the distance between the rear ends is 1.2m. Therefore, the area of ​​the region enclosed by the two bottom beams (i.e., the area of ​​the isosceles trapezoid formed by the two bottom beams as the two legs) is A3 = 1.31m². 2 At this point, A3:A1≈0.36.

[0040] Example 3: In this example, the length of the stone tabletop is 2.64m and the width is 1.36m, therefore A1 = 3.5904m. 2 ; like Figure 1As shown, the top support frame 2 includes two parallel support beams. Each support beam has a number of leveling bolts 3 evenly spaced as support sections. The area enclosed by the leveling bolts 3 is A2 = 2.25m². 2 That is, A2:A1≈0.63.

[0041] like Figure 3 As shown, the bottom support frame 1 includes two bottom beams, one on the left and one on the right (i.e., the horizontal axis of the billiard table). Each bottom beam includes a longitudinally arranged long support beam 101 and a short support beam 102, one end of which is connected to the front end of the long support beam 101 and the other end of which slopes outward. The two long support beams 101 are arranged in a V-shape, and the front end of the long support beam 101 does not extend beyond the short support beam 102. The two bottom beams are supported on the ground, and the area of ​​the region enclosed by the two bottom beams (i.e., the area of ​​the quadrilateral enclosed by the four vertices of the two bottom beams connected end to end) A3 = 1.92m². 2 At this point, A3:A1≈0.53.

[0042] Example 4: In this example, the length of the stone tabletop is 2.64m and the width is 1.36m, therefore A1 = 3.5902m. 2 ; like Figure 1 As shown, the top support frame 2 includes two parallel support beams. Each support beam has a number of leveling bolts 3 evenly spaced as support sections. The area enclosed by the leveling bolts 3 is A2 = 2.25m². 2 That is, A2:A1≈0.63.

[0043] like Figure 4 As shown, the bottom support frame 1 includes two bottom beams, one on the left and one on the right (i.e., the horizontal axis of the billiard table). Each bottom beam includes a longitudinally arranged long support beam 101 and a short support beam 102, one end of which is connected to the front end of the long support beam 101 (i.e., the non-endpoint position of the front end), and the other end of which slopes outward. The two long support beams 101 are arranged in a V-shape, with the front ends of the two long support beams extending beyond the short support beam 102. The two bottom beams are supported on the ground, and the area of ​​the region enclosed by the two bottom beams (i.e., the area of ​​the quadrilateral enclosed by connecting the vertices of the two bottom beams end to end) is A3 = 2.03m². 2 At this point, A3:A1≈0.57.

[0044] Example 5: In this example, the length of the stone tabletop is 2.64m and the width is 1.36m, therefore A1 = 3.5902m. 2 ; like Figure 1 As shown, the top support frame 2 includes two parallel support beams. Each support beam has a number of leveling bolts 3 evenly spaced as support sections. The area enclosed by the leveling bolts 3 is A2 = 2.25m².2 That is, A2:A1≈0.63.

[0045] like Figure 5 As shown, the bottom support frame 1 includes two bottom beams, one on the left and one on the right (i.e., the horizontal axis of the billiard table). Each bottom beam includes a longitudinally arranged long support beam 101 and a short support beam 102, one end of which is connected to the front end of the long support beam 101 (i.e., the non-endpoint position of the front end), and the other end of which slopes outward. The two long support beams 101 are arranged in a V-shape. Each bottom beam has three supporting legs extending from its lower end to support it on the ground. One leg is located below the front vertex of the long support beam 101, serving as the front support leg 105; one leg is located below the connection between the long support beam 101 and the short support beam 102, serving as the middle support leg 106; and the other leg is located below the rear vertex of the long support beam 101, serving as the rear support leg 104. The area enclosed by the two bottom beams is the area of ​​the polygon enclosed by connecting each support leg in sequence, A3 = 1.54m. 2 At this point, A3:A1≈0.43.

[0046] Example 6: In this example, the length of the stone tabletop is 2.64m and the width is 1.36m, therefore A1 = 3.5902m. 2 ; like Figure 1 As shown, the top support frame 2 includes two parallel support beams. Each support beam has a number of leveling bolts 3 evenly spaced as support sections. The area enclosed by the leveling bolts 3 is A2 = 2.25m². 2 That is, A2:A1≈0.63.

[0047] In this embodiment, the structure of the bottom support frame 1 is the same as that of embodiment 5 above, the only difference being the size of the long support beam 101; as Figure 6 As shown, in this embodiment, compared to embodiment 5, the rear support leg 104 moves forward by 0.4m; at this time, the area enclosed by the two bottom beams is the area of ​​the polygon enclosed by the sequentially connected support legs, A3 = 1.12m. 2 At this point, A3:A1≈0.3.

[0048] It can be understood that: the above embodiments 5 and 6 only provide one way of setting the support legs. It is also possible to use other positions to arrange the support legs under the bottom beam. The support area of ​​the bottom support frame 1 on the ground is the area of ​​the polygon enclosed by the sequential connection of each support leg.

[0049] Simulation analysis: The constraint boundary for reducing the projected area of ​​the billiard table support on the ground is the stability under offset load. Consider the extreme scenario of a 75kg person impacting the billiard table from the side, pressing their body against one side or corner of the table, and using a safety factor of 1.5, i.e., a load of 150kg. The offset load on the billiard table is as follows: Figure 7 As shown.

[0050] In this example, the method used is... Figure 7 The minimum ground projection area A3 required to prevent the billiard table from overturning under the extreme bias load shown is used to derive the lower limit of the safe ratio of A3 to the slate tabletop area A1.

[0051] For the outrigger-supported schemes in Examples 5 and 6, the necessary and sufficient condition for their stability is that, under any load, the support reaction force at all support points is constant. All are positive values ​​(i.e., pressure), that is:

[0052] Where: n is the total number of support points, i.e., the legs (in both Embodiment 5 and Embodiment 6, there are 6 legs). When the support reaction force of a certain support leg is 0, it indicates that the support leg is about to leave the ground, and the billiard table support is in a critical state of rotation around the "overturning axis" formed by the lines connecting the other support legs. Therefore, detecting that the support reaction force of any one of the support legs is 0 can be determined as unstable.

[0053] During the simulation, the mechanical energy rigid body kinematics of the billiard table support is solved under given loads and geometric configuration in the software. The magnitude of the support reaction force of each support leg is calculated under the given load. Then, the minimum stable area is calculated by using the forward movement distance ΔL=10cm of the rear support leg as the iteration variable. That is, the projected area of ​​the bottom support frame on the ground is updated (reduced) by moving the rear support leg forward. After each iteration, a stability judgment is made. When the support reaction force of a certain support leg is 0, it indicates that the billiard table support has reached or exceeded the overturning critical point, and the current area A3 is the unstable area.

[0054] In this specific example, the above-mentioned Embodiment 5 (let's call it Condition 1) and Embodiment 6 (let's call it Condition 5) are compared respectively. Compared to Embodiment 5, Condition 2 is defined as moving the rear support leg 104 forward by 0.1m (i.e., shortening the long support beam 101 by 0.1m); Condition 3 is defined as moving the rear support leg 104 forward by 0.2m (i.e., shortening the long support beam 101 by 0.2m); and Condition 4 is defined as moving the rear support leg 104 forward by 0.3m (i.e., shortening the long support beam 101 by 0.3m). Simulation calculations are performed on the billiard table under offset loads under the five conditions. The calculations show that under Conditions 1-4, the billiard table can still remain stable under offset loads at any position, indicating that the ground contact projection area under these four conditions has redundancy; under Condition 5, in Figure 7 When an offset load is applied at position 2, the supporting reaction force of one of the front legs is already 0, indicating that the stability boundary has been reached; at this time, the supporting area of ​​the bottom support frame 1 on the ground is 1.12m2; this shows that in order to ensure the overturning stability of the billiard table under extreme offset load, the ratio of the ground projection area of ​​its bottom support frame to the slate table area should not be less than 0.3.

[0055] It can be understood that in the above embodiments 1-6, only the ratio of the support area of ​​the top support frame 2 on the slate table to the area of ​​the billiard table slate table and the ratio of the support area of ​​the top support frame 2 on the slate table to the area of ​​the billiard table slate table are considered, and the specific structure of the top support frame 2 and the bottom support frame 1 is not limited.

[0056] As an example, in Embodiments 5 and 6, the middle support leg 106 is a fixed support leg, and the front support leg 105 and / or the rear support leg 104 adopts a leveling foot (that is, the front support leg 105 can be a leveling foot and the rear support leg 104 can be a fixed support leg, or the rear support leg 104 can be a leveling foot and the front support leg 105 can be a fixed support leg, or both the front support leg 105 and the rear support leg 104 can be leveling feet). If a leveling foot with a wedge structure is adopted, the levelness of the billiard table support can be adjusted by the leveling foot.

[0057] Example 7: Based on the above embodiments 1-6, further: Because billiard tables are typically installed in noisy environments with various frequencies of sound waves and vibrations, the stability and accuracy of the billiard table frame can be affected. To ensure the performance of the billiard table frame, it is necessary to analyze the vibration modes of the billiard table, and then consider the vibration patterns for different installation environments. By optimizing the billiard table structure, resonance can be avoided.

[0058] To improve the adaptability of the billiard table frame in different environments, a detachable adjustment beam is provided on the frame. As an example, the detachable adjustment beam includes adjustment beam A along the longitudinal direction (length direction) of the billiard table and adjustment beam B along the transverse direction (width direction). When the billiard table encounters vibration excitation close to its natural frequency in the working environment, the detachable adjustment beam can alter the billiard table structure to prevent resonance.

[0059] Therefore, before installing the billiard table, a vibration modal analysis is performed on the billiard table frame to capture its principal mode shape, extract the main vibration modes of the billiard table frame, and obtain the natural frequencies of the billiard table frame under the main vibration modes. After the billiard table frame is installed, the vibration excitations that the environment may receive are investigated to obtain the frequency range of these vibration excitations. If the billiard table frame is likely to have coupled resonance with these vibration excitations, simply install an adjustment beam in the direction of the vibration excitation to adjust the natural frequency of the billiard table frame and prevent it from coinciding with the vibration frequency of the vibration excitation.

[0060] With the addition of a detachable adjustable beam, the overall structure of the billiard table frame can be adjusted without altering its design when installing in different environments. The natural frequency of the billiard table frame can be adjusted simply by installing the detachable adjustable beam based on the vibration excitation in the current environment.

[0061] As an example, a vibration modal analysis was performed on a billiard table support with a specific structure. The simulation analysis focused on the first 15 modes. The results showed that the total effective mass of the first 15 modes was greater than 95%, indicating that the principal mode shapes had been captured. The main vibration modes of the billiard table support (the 1st, 9th, and 15th modes) were extracted from these 15 modes, and the natural frequencies of the support under these modes were obtained (40.13Hz, 114.5Hz, and 154.3Hz, respectively).

[0062] However, considering that billiard tables in daily life are mostly subjected to single-degree-of-freedom vibration excitations, such as left-right swaying, back-and-forth swaying, and up-and-down swaying, the first-order mode of the billiard table support can be understood as left-right swaying in the width direction of the billiard table. Its effective mass is greater than its front-and-back and vertical directions, indicating that this is the dominant natural frequency. Care should be taken to avoid subjecting this direction to vibration excitations with the same frequency as the natural frequency of the billiard table support in the first-order mode.

[0063] Research revealed that the main sources of vibration affecting urban residential buildings include: large machinery, such as central air conditioning units; and transportation vehicles, such as subways, light rail, and buses. Subway operation generates the most significant vibration excitation on buildings, with frequencies ranging from 40Hz to 80Hz, varying depending on the building's structure and its location relative to the subway. Modal analysis of the billiard table support indicates that if a subway line operates within the area where the billiard table is located, there is a possibility of coupled resonance between the billiard table support and the vibration excitation generated by the subway. Therefore, installing a support frame along the width of the billiard table support can prevent the vibration frequencies from coinciding with those generated by the subway.

[0064] Example 8: Based on the above embodiments 1-7, the billiard table support is made of metal, and the overall frame is made of sheet metal, specifically steel plate.

[0065] Existing metal billiard table supports mostly use steel plates of 3mm to 4mm thickness, resulting in a large design stiffness redundancy. Considering that billiard tables generally operate in a static environment, there is room for further reduction in this redundancy. Therefore, modifying the thickness of the steel plate in the billiard table support can be achieved by using steel plates with a thickness of less than 2.5mm, preferably 1.5mm to 2.5mm. This can reduce weight, saving steel and reducing transportation costs.

[0066] As an example, if the original 3mm and 4mm thick steel plates of a billiard table frame are replaced with 2mm thick steel plates, the overall weight will be reduced from 264.2kg to 154.5kg, a reduction of 41.5%. Furthermore, static analysis and dynamic simulation analysis under impact bias of the modified billiard table structure show that the stability and safety of the billiard table frame under the condition of thin plate (2mm thick steel plate) meet the requirements.

[0067] Simulation Description: Similarly, billiard tables with frames made of 4mm thick steel plate and billiard tables with frames made of 2mm thick steel plate were subjected to different applications. Figure 7 The simulation analysis of the bias load shown indicates that, in both cases, the stress inside the billiard table support under the bias load is much less than the strength limit of Q235 steel, and the overall safety system exceeds 3.

[0068] Example 9: Based on the above embodiments 1-8, this embodiment provides a specific structural form of a billiard table support.

[0069] The billiard table support includes: a bottom support frame 1 and a top support frame 2; as shown in the image. Figure 8 As shown, the top support frame 2 includes two longitudinally extending support beams 201 and a crossbeam for laterally connecting the two support beams 201; six leveling bolts 3 are distributed longitudinally at intervals on each support beam 201 to support the panel assembly.

[0070] The bottom support frame 1 includes two long support beams 101 on the left and right. The two long support beams 101 are distributed in a figure-eight shape. The lower end of the long support beam 101 is a horizontal plane and is supported on the ground. The upper end is a sloping plane, and the rear part of the upper end is inclined upward and connected to the top support frame 2. In addition, the long support beam 101 is connected to the support beam 201 on the corresponding side by several support rods 103.

[0071] The two long support beams 101 are connected together by several connecting beams. As an example, the two long support beams 101 are connected together by two X-shaped connecting beams.

[0072] In addition, each long support beam 101 has an outwardly flared short support beam 102 on its outer side at the front end. This can be understood as the long support beam 101 and the short support beam 102 together forming a V-shaped bottom beam. The short support beam 102 is supported on the ground.

[0073] As an example, a front support leg 105 is provided below the front end of the short support beam 102; a middle support leg 106 is provided below the position of the long support beam 101 for leading out the short support beam 102; and a rear support leg 104 is provided at the lower end of the long support beam 101. The billiard table bracket is supported on the ground by two front support legs 105, two middle support legs 106 and two rear support legs 104.

[0074] As an example, the front and middle legs are fixed legs, while the rear leg uses a leveling foot. For example, a leveling foot with a wedge-shaped structure can be used to adjust the level of the billiard table support.

[0075] In this example, the thickness of the steel plates used to form the bottom support frame 1 and the top support frame 2 is 2 mm.
