Abstract
Description
Technical Field
[0001] This utility model belongs to the field of billiard table technology, specifically relating to an extension for the edge of the table and a table edge and billiard table having the extension. Background Technology
[0002] A typical billiard table consists of a tabletop, sidewalls, and multiple legs. The legs support the bottom of the tabletop, while the sidewalls are fixed around the perimeter of the tabletop to form the structure where the balls strike. The tabletop is made of slate and a cloth laid on top of the slate.
[0003] like Figure 1 As shown, an existing table edge includes a rubber strip 2, a steel plate 4, a lower wooden strip 110, 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 a tablecloth 1. One end of the tablecloth 1 is pressed into a groove on the outer side of the steel plate 4 by a pressure strip 3 (one end of the tablecloth 1 is fixed between the steel plate 4 and the wooden handrail 5), and the other end is pressed between the stone slab 7 and the backing wooden strip 11 (generally, the tablecloth 1 also needs to be fastened to the wooden strip by nails fired from a nail gun). Figure 1 (Not shown in the image). In the aforementioned platform edge, the steel plate 4, the lower lining wooden strip 10, the backing wooden strip 11, and the wooden handrail 5 constitute the main structure of the platform edge.
[0004] Reference Figure 2 ( Figure 2 It is an integrated warehouse-side system, and the integrated warehouse-side system has no... Figure 1 The steel plate 4 and the backing wooden strips 11 are part of the structure. Figure 2 This is used to illustrate the installation status of the two ends of the adhesive strip. Figure 1 Installation status of the two ends of the middle rubber strip and Figure 2 The installation of the middle rubber strip 2 is the same. The end of the rubber strip 2 on the edge of the table needs to be bent (corresponding to the pocket position of the pool table) and glued to the wooden handrail 5. Similarly, for Figure 1Regarding the table edge structure, most of the length of the rubber strip 2 is to be bonded to the backing wood strip 11, and the two ends of the rubber strip 2 need to be bent and bonded to the ends of the wooden handrail 5. During the billiard table manufacturing process, the applicant noticed a problem: because the ends of the rubber strip 2 need to be sanded after the ends are bent and bonded, the ends of the rubber strip 2 are supported by the ends of the wooden handrail 5. For a long time, the sanding of the ends of the rubber strip 2 has been done after the rubber strip 2 has been bonded to the ends of the wooden handrail 5. This means that the rubber strip 2 can only be installed and the sanding of the ends of the rubber strip 2 can only be done after the wooden handrail 5 has been manufactured and fixed to the steel plate 4 (at which point the ends of the rubber strip 2 are supported by the ends of the wooden handrail 5). This leads to a decrease in the production efficiency of the billiard table. Another problem is that after sanding the ends of the rubber strip 2, in order to install the table cloth 1, the wooden handrail 5 needs to be removed first, and then the pressure strip 3 is pressed into the groove on the outside of the steel plate 4. Then the wooden handrail 5 is fixed to the steel plate 4. The process is cumbersome and further reduces the production efficiency of the billiard table. Utility Model Content
[0005] In view of this, the present invention provides an extension for the table edge and a table edge and a billiard table having the extension, which solves the technical problem of reduced billiard table production efficiency caused by grinding the ends of the rubber strips and installing the table cloth.
[0006] The table edge extension provided by this utility model adopts the following technical solution:
[0007] An extension for a table edge, wherein the extension is fixed to the longitudinal end of a backing wooden strip on the inner side of a table edge steel plate, and then extends to the outer side of the steel plate.
[0008] After the middle of the adhesive strip on the edge of the table is glued to the backing wood strip, the end of the adhesive strip can be bent and glued to the extension.
[0009] Furthermore, the extension is provided with at least one first screw hole for fixed connection with the steel plate by fastening screws;
[0010] The extension is at least partially made of metal.
[0011] Furthermore, the extension includes a metal portion and a plastic portion;
[0012] The metal part and the plastic part are fixedly connected. The plastic part allows the nails used for fastening the cloth to be inserted to fix the cloth.
[0013] The volume of the metal part can be larger than the volume of the plastic part, in which case the metal part can provide an adhesive surface for the end of the adhesive strip.
[0014] Furthermore, the volume of the plastic part can be made larger than the volume of the metal part. In this case, the designated area of the metal part and the designated area of the plastic part can jointly provide an adhesive surface for the end of the adhesive strip.
[0015] Furthermore, the plastic part is provided with a positioning post, and the metal part is provided with a positioning hole. When the plastic part and the metal part are assembled, the positioning post passes through the positioning hole, so that the metal part cannot rotate relative to the plastic part.
[0016] After the extension is fixed to the steel plate, the metal part of the extension is clamped and fixed between the steel plate and the plastic part;
[0017] At least one of the positioning posts is provided with a threaded hole, and the positioning post with the threaded hole is also used to connect the extension to the steel plate.
[0018] Furthermore, the positioning post is disposed in the cavity of the plastic part, and a rib is disposed in the cavity. The height of the positioning post extending beyond the rib is equal to the depth of the positioning hole.
[0019] The number of positioning pins and positioning holes are both three, and one of the positioning pins is provided with a threaded hole.
[0020] Furthermore, the extension is made of metal;
[0021] After the extension is fixed to the longitudinal end of the backing wood strip on the edge of the table, at least a portion of the structure of the extension forms a gap with the inner side of the steel plate on the edge of the table, and the end (the end in the length direction) of the backing wood strip can extend into the gap.
[0022] Furthermore, the extension is provided with at least one second screw hole for fixed connection with the backing wood strip by fastening screws.
[0023] This utility model also provides a table edge, on which any of the above-mentioned table edge extensions are installed.
[0024] This utility model also provides a billiard table, wherein the billiard table is equipped with the aforementioned table edge.
[0025] Beneficial effects:
[0026] 1. This utility model provides an extension for the table edge. Because the extension is fixed to the longitudinal end of the backing wood strip of the table edge, it extends to the outside of the steel plate. This allows the middle of the rubber strip of the table edge to be bonded to the backing wood strip, and the end of the rubber strip to be bonded to the extension. At this point, the end of the rubber strip is already bonded to the extension, providing support. This allows for the curvature grinding of the rubber strip end without waiting for the wooden handrail to be assembled with the steel plate, thus improving the production efficiency of the billiard table. Furthermore, after the rubber strip is installed and ground, one end of the table cloth can be fixed between the steel plate and the wooden handrail. The wooden handrail only needs to be installed once, avoiding the cumbersome process of installing and then removing and reinstalling the wooden handrail, further improving the production efficiency of the billiard table.
[0027] 2. The extension includes a metal part and a plastic part, which are fixedly connected. The plastic part allows nails for fastening the tablecloth to be inserted to secure it. In this way, the extension does not affect the installation of the tablecloth, and it does not need to be designed as an all-metal component, reducing the amount of metal used.
[0028] 3. The volume of the plastic part on the extension is larger than the volume of the metal part, thus further saving the amount of metal material used in the extension.
[0029] 4. The extension piece is provided with at least one first screw hole for fixing to the steel plate by fastening screws. In this way, the extension piece can be fixedly installed on the longitudinal end of the backing wood strip by connecting to the steel plate with fastening screws. The installation structure is simple and easy to install and remove.
[0030] 5. The extension is made of metal. After the extension is fixed to the longitudinal end of the backing wood strip on the edge of the table, at least a portion of the extension structure forms a gap with the inner side of the steel plate on the edge of the table, allowing the end of the backing wood strip to extend into the gap. In this way, the end of the backing wood strip can extend into the gap formed between the extension and the inner side of the steel plate on the edge of the table. Since this gap is filled by the backing wood strip instead of the extension itself, the amount of metal used in the extension is reduced, and the nails used to fix the tablecloth can be fixed to the backing wood strip extending into the gap without affecting the installation of the tablecloth.
[0031] 6. The metal part of the extension is provided with positioning holes and the plastic part is provided with positioning pins. The plastic part and the metal part are assembled by the cooperation of the positioning holes and positioning pins. The processing is simple and convenient and the cost is low.
[0032] 7. At least one positioning post is provided with a threaded hole. The positioning post with the threaded hole can engage with the thread of the fastening screw, so that the positioning post with the threaded hole is not only used to engage with the positioning hole, but also serves to fix the extension to the steel plate by the fastening screw.
[0033] 8. The extension piece is provided with at least one second screw hole for fixed connection to the backing wood strip by fastening screws. In this way, the extension piece can be fixedly installed to the longitudinal end of the backing wood strip by connecting it to the backing wood strip with fastening screws. The installation structure is simple and easy to install and remove. Moreover, it can avoid the need to specially set up fastening screw holes or other installation structures for installing the extension piece on the steel plate, further facilitating the installation and removal of the extension piece.

Detailed Implementation
[0058] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0059] Example 1:
[0060] Referring to the existing technology Figure 1 and Figure 2 and referring to this embodiment Figures 3 to 10 This embodiment provides a table edge extension 13. After the extension 13 is fixed to the longitudinal end of the backing wood strip 11 inside the table edge steel plate 4, the extension 13 extends to the outer side of the steel plate 4. After the middle part of the table edge adhesive strip 2 is glued to the backing wood strip 11, the end of the adhesive strip 2 (the end in the length direction) can be bent and glued to the extension 13.
[0061] Thus, because the extension 13 is fixed to the longitudinal end of the backing wood strip 11 of the table edge, the extension 13 extends to the outside of the steel plate 4. This allows the middle of the rubber strip 2 of the table edge to be bonded to the backing wood strip 11, and the end of the rubber strip 2 to be bonded to the extension 13. At this point, the end of the rubber strip 2 is already bonded to the extension 13, and with support at the end of the rubber strip 2, the end of the rubber strip 2 can be arc-polished without waiting for the wooden handrail 5 to be assembled with the steel plate 4, thus improving the production efficiency of the billiard table. Moreover, after the rubber strip 2 is installed and polished, one end of the table cloth 1 can be fixed between the steel plate 4 and the wooden handrail 5. The wooden handrail 5 only needs to be installed once, avoiding the cumbersome process of installing and then removing and reinstalling the wooden handrail 5, further improving the production efficiency of the billiard table.
[0062] It is understandable that, in order to avoid interference between the extension structure of the extension member 13 extending to the outside of the steel plate 4 and the assembly of the wooden handrail 5 to the outside of the steel plate 4, those skilled in the art can avoid the so-called possible interference by setting a small notch structure or a notch at the end of the wooden handrail 5, or by flexibly changing the size of the end of the wooden handrail 5.
[0063] In this embodiment, the extension member 13 includes a metal part 1301 and a plastic part 1302. The metal part 1301 and the plastic part 1302 are preferably fixedly connected by adhesive bonding. The plastic part 1302 allows the nails used for fastening the fabric 1 to pass through and fix the fabric 1. Moreover, the volume of the metal part 1301 is larger than that of the plastic part 1302, and the metal part 1301 provides an adhesive surface for the end of the adhesive strip 2. In addition, the extension member 13 is provided with at least one first screw hole 1303 for fixed connection with the steel plate 4 by fastening screws.
[0064] Example 2:
[0065] This embodiment provides an extension 13 with another structure, referring to the background art. Figure 1 and Figure 2 and this embodiment Figures 11 to 15In this embodiment, the extension 13, like in Embodiment 1, also includes a metal part 1301 and a plastic part 1302, and the extension 13 is provided with at least one first screw hole 1303 for fixed connection with the steel plate 4 by fastening screws. However, in this example, the volume of the plastic part 1302 of the extension 13 is larger than the volume of the metal part 1301, and the setting area of the metal part 1301 and the setting area of the plastic part 1302 together provide an adhesive surface for the end of the adhesive strip 2.
[0066] Example 3:
[0067] This embodiment provides an extension 13 with another structure, referring to the background art. Figure 1 and Figure 2 and this embodiment Figures 16 to 19 In this embodiment, the extension member 13 is made of metal. After the extension member 13 is fixed to the longitudinal end of the backing wood strip 11 on the edge of the table, at least a portion of the structure of the extension member 13 forms a gap with the inner side of the steel plate 4 on the edge of the table, and the end (the end in the length direction) of the backing wood strip 11 can extend into the gap. The nails for fixing the tablecloth 1 can be fixed with the backing wood strip 11 extending into the gap without affecting the installation of the tablecloth 1.
[0068] Example 4:
[0069] This embodiment provides an extension 13 with another structure, referring to the background art. Figure 1 and Figure 2 and this embodiment Figures 20 to 23 The structure of the extension 13 in this embodiment is generally the same as that of the extension 13 in Embodiment 2, and also includes a metal part 1301 and a plastic part 1302. The extension 13 is provided with at least one first screw hole 1303 (two are provided in this embodiment) for fixed connection with the steel plate 4 by fastening screws. The volume of the plastic part 1302 of the extension 13 is larger than the volume of the metal part 1301. The setting area of the metal part 1301 and the setting area of the plastic part 1302 together provide an adhesive surface for the end of the adhesive strip 2.
[0070] Unlike the extension 13 in Embodiment 2, where the metal part 1301 and plastic part 1302 of the extension 13 can be fixed together by adhesive, in this embodiment, the metal part 1301 and plastic part 1302 of the extension 13 are preferably fixed together by a mechanical structure. Specifically, in this embodiment, the metal part 1301 of the extension 13 is provided with a positioning hole 14. The positioning hole 14 on the metal part 1301 and the positioning post 15 provided on the plastic part 1302 can be correspondingly engaged. When the plastic part 1302 and the metal part 1301 are assembled, the positioning post passes through the positioning hole 14, preventing the metal part 1301 from rotating relative to the plastic part 1302, so that the metal part 1301 can be positioned on the plastic part 1302. After the plastic part 1302 on the extension 13 is fixed on the steel plate 4, the metal part 1301 is clamped and fixed between the steel plate 4 and the plastic part 1302.
[0071] For example, in this embodiment, there are three positioning holes 14 and three corresponding positioning posts 15. When the metal part 1301 and the plastic part 1302 are assembled, each positioning post 15 passes through one positioning hole 14. More specifically, the plastic part 1302 is provided with a cavity 16, and the positioning post 15 is disposed in the cavity 16. A rib is provided in the cavity 16, and the height of the rib is less than the height of the positioning post 15. The height of the positioning post 15 exceeding the rib is exactly equal to the depth of the positioning hole 14 on the metal part 1301. This allows the metal part 1301 to be installed onto the plastic part 1302. After the plastic part 1302 is attached to the steel plate 4, one surface of the plastic part 1302 that is fixedly attached to the steel plate 4 can remain flat. Moreover, at least one positioning post 15 is provided with a threaded hole. The positioning post 15 with the threaded hole can engage with the thread of the fastening screw, so that the positioning post 15 with the threaded hole is not only used to engage with the positioning hole 14, but also serves to fix the extension 13 to the steel plate 4 by the fastening screw (at this time, for the positioning post 15 with the threaded hole, its threaded hole belongs to one of the two first screw holes 1303 on the extension 13). In this embodiment, the metal part 1301 and the plastic part 1302 are assembled by engaging the positioning post 15 with the positioning hole 14, which is simple and convenient to process and has low cost.

[0073] This embodiment provides a table edge on which an extension member 13 for the table edge of any of the above embodiments is installed.
[0074] Example 6:
[0075] This embodiment provides a billiard table, which is equipped with the table edge as described in Embodiment 5.
[0076] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
