[0002] Commonly used fixtures such as tatami mats, windows, or basements include covers for enclosing spaces, and these covers usually have handles for easy opening. However, if the handles are directly exposed outside the cover, on the one hand, the handles will protrude from the top surface of the cover, which may pose a safety hazard. For example, users may accidentally bump into the handles. On the other hand, protruding handles are not flat and will affect the overall aesthetics of the cover.

[0003] Therefore, it is necessary to propose an improved handle structure for the cover plate to avoid the above-mentioned problems while meeting the user's needs. Utility Model Content

[0004] In view of this, one object of this application is to provide a pull ring kit in which the pull ring can be exposed when the cover needs to be opened so that the user can open the cover, and can be hidden when the cover does not need to be opened so as to avoid obstruction or affect the aesthetics.

[0005] Another objective of this application is to enable pull rings to have both high strength and low weight.

[0006] Another objective of this application is to improve the user's tactile experience, making it easier for the user to rotate the pull tab out of the pull tab holder and to enhance the overall design of the visible surface.

[0007] Another objective of this application is to limit the rotational stroke of the pull ring to within 180° by cooperating the stop portion of the pull ring with the recess of the pull ring seat, thereby preventing the pull ring from wobbling up and down and making it easier for the user to grip the pull ring.

[0008] According to a first aspect of this application, a pull ring kit is provided, comprising a pull ring and a pull ring seat, the pull ring seat being adapted to be fixed to the upper surface of a cover plate, the pull ring being mounted in the pull ring seat such that it can be rotated relative to the pull ring seat in a vertical plane to switch between an exposed position and a concealed position. The pull ring includes a handle, a pull ring bottom, and a reinforcement located between the handle and the pull ring bottom, the reinforcement being disposed on both sides of the pull ring bottom, and the reinforcement having a weight-reducing portion formed by an inward recess from the surface of the reinforcement. When the pull ring is in the exposed position, the handle extends completely from above the pull ring seat, and the lower surface of the pull ring bottom faces downward and is invisible; and when the pull ring is in the concealed position, the lower surface of the pull ring bottom faces upward, and the handle is completely located in the pull ring seat and is invisible.

[0009] In some embodiments, the pull ring seat includes a seat skirt and a seat sleeve extending vertically from the seat skirt. The seat skirt is adapted to be fixed to the upper surface of the cover plate, and the seat sleeve is adapted to be located in a groove of the cover plate. The seat sleeve includes seat fastening portions located on both sides and a pull ring receiving cavity that extends vertically through the middle. The seat skirt is arranged around the upper opening of the pull ring receiving cavity.

[0010] In some embodiments, the upper surface of the seat skirt is configured as an inwardly curved arcuate surface.

[0011] In some embodiments, the middle portion of the lower surface of the bottom of the pull ring is configured to protrude outward relative to the two side portions of the lower surface of the bottom of the pull ring.

[0012] In some embodiments, the handle has a stop on only one side, and the inner wall of the pull ring receiving cavity has recesses on each of the two sides for engaging the stop.

[0013] In some embodiments, the bottom of the pull ring is provided with a pin mounting portion having a first mounting hole at the middle, and the two opposite sidewalls of the pull ring receiving cavity are each provided with a second mounting hole corresponding to the first mounting hole at the middle, so that the pull ring can be rotatably mounted in the pull ring receiving cavity via a pin.

[0014] In some embodiments, the pull ring assembly further includes a cover disposed below the seat sleeve and adapted to be fixed to the lower surface of the cover plate, and the cover has a cover fastening portion corresponding to the seat fastening portion and a cover opening corresponding to the pull ring receiving cavity.

[0015] In some embodiments, the pull ring seat, pull ring, and cover are each integrally molded plastic parts by an injection molding process.

[0016] According to a second aspect of this application, a cover is provided having a pull ring assembly according to any embodiment of the first aspect or a combination thereof.

[0017] According to a third aspect of this application, an apparatus is provided that includes a cover plate according to an embodiment of the second aspect.

[0018] The pull ring kit according to an embodiment of this application includes a pull ring and a pull ring seat mounted together. The pull ring is rotatable relative to the pull ring seat to switch between an exposed position and a concealed position. With this structural design, when it is necessary to open the cover, the user can rotate the pull ring to the exposed position to open the cover using the pull ring; when it is not necessary to open the cover, the pull ring is concealed and does not protrude from the cover, thus eliminating safety hazards and maintaining aesthetics. The pull ring kit according to an embodiment of this application also includes a cover disposed on the lower surface of the cover to cover the lower opening of the recess in the cover, thereby improving safety and aesthetics, as well as enhancing the stability of the pull ring installation. Furthermore, the pull ring also has a reinforcing portion including a weight-reducing part, thus achieving high strength while maintaining a light weight. In addition, a stop portion is provided on the side of the pull ring. By cooperating with the recess of the pull ring seat, the rotational stroke of the pull ring is limited to within 180°, preventing the pull ring from wobbling up and down, and facilitating the user's grip on the pull ring. In addition, the upper surface of the skirt of the pull ring seat is constructed as an inwardly curved arc surface, and the middle part of the lower surface of the bottom of the pull ring is constructed to protrude outward relative to its two sides. This structural design can improve the user's tactile feel, make it easier for the user to rotate the pull ring out of the pull ring seat, and enhance the overall design of the visible surface.

[0030] The following description is exemplary in nature and is not intended to limit the invention, its applications, or uses. The accompanying drawings are only schematic representations of the concept and principles of embodiments of the invention and do not necessarily show the specific dimensions and proportions of each embodiment. Certain details or structures of embodiments of the invention may be exaggerated in specific parts of particular drawings.

[0031] In the description of embodiments of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or a limitation of number. The term "a plurality of" refers to two or more unless otherwise expressly defined. The directional terms used in relation to "upper," "lower," and "side (part)" are used to describe the position or orientation shown in the drawings or the conventional position or orientation in actual use. The vertical direction Y refers to the direction perpendicular to the upper surface of the cover plate or the depth direction of the groove on the cover plate for mounting the pull ring assembly, wherein the upper surface of the cover plate is the surface visible when the cover plate is closed, and the lower surface of the cover plate is the surface opposite to the upper surface of the cover plate. The horizontal direction X refers to the direction along the length of the cover plate. The vertical plane XY refers to the plane formed by the vertical direction Y and the horizontal direction X together.

[0032] This application provides two embodiments of the pull ring assembly 1. In the first embodiment, the pull ring assembly 1 includes a pull ring seat 12 and a pull ring 11 mounted in the pull ring seat 12, the pull ring 11 being mounted to be rotatable relative to the pull ring seat 12 in a vertical plane XY (see [link]). Figure 6 The pull ring 11 and pull ring seat 12 are designed to switch between exposed and concealed positions. The specific structure of these components will be described below in conjunction with the accompanying drawings. Figure 1The illustration shows a pull ring assembly 1 according to a first embodiment of this application mounted on a cover plate 2, wherein the pull ring 11 is generally invisible, i.e., in a hidden position. When a user applies force to the bottom of the pull ring 11, the pull ring 11 can be rotated from the hidden position to the exposed position, thereby exposing the pull ring 11 so that the user can pull up the cover plate 2 by means of the pull ring 11.

[0033] The following will combine Figures 2 to 7 The structure of the pull ring 11 and pull ring seat 12 of the pull ring kit 1 according to the first embodiment will be described in further detail.

[0034] Figure 2 The structure of the pull ring 11 of the pull ring assembly 1 according to the first embodiment is schematically shown. Figure 2 As shown, the pull ring 11 may include a handle 111, a pull ring bottom 112, and a reinforcing portion 113 located between the handle 111 and the pull ring bottom 112.

[0035] For example, the handle 111 as a whole can be constructed as an arch, and the edges of the handle 111 can be rounded to improve the user's grip and the aesthetics of the pull ring. For example, the cross-sectional shape of the handle 111 can be circular. The bottom 112 of the pull ring can be constructed between the two ends of the handle 111, so that the handle 111 and the bottom 112 of the pull ring form a closed, approximately semi-circular ring.

[0036] See you again Figure 1 As shown in the assembly diagram, when the pull ring 11 is in the hidden position, the lower surface 116 of the pull ring bottom 112 faces upward and is oriented along the horizontal direction X, so that the lower surface 116 is fully visible and can close the upper opening of the pull ring receiving cavity 124 (described further below), at which time the handle 111 is completely invisible; when the pull ring 11 is in the exposed position, the handle 111 extends completely from above the pull ring seat 12 and the lower surface 116 of the pull ring bottom 112 faces downward and is oriented along the horizontal direction X.

[0037] See Figure 2The reinforcing portions 113 can be arranged on both sides of the bottom 112 of the pull ring, meaning the pull ring 11 has two reinforcing portions 113. The reinforcing portions 113 can be constructed in a generally triangular shape, for example, to effectively improve the overall strength of the pull ring and resist excessive pulling forces under certain extreme conditions, ensuring that the pull ring 11 is not deformed or broken. The edges of the reinforcing portions 113 can be constructed with a certain curvature. In particular, the reinforcing portions 113 have curved portions at their respective connections with the handle 111 and the bottom 112 of the pull ring to avoid stress concentration. Furthermore, the reinforcing portions 113 can, for example, have a triangular-shaped weight-reducing portion 114 formed by inward indentation from the surface of the reinforcing portion in the middle, to prevent the overall weight of the pull ring 11 from becoming excessive. In this embodiment, the depth of the inward indentation of the weight-reducing portion 114 is less than the thickness of the reinforcing portion 113, meaning the weight-reducing portion 114 does not penetrate the thickness of the reinforcing portion 113.

[0038] To achieve rotation of the pull ring 11 relative to the pull ring seat 12, see [link / reference]. Figure 2 The bottom 112 of the pull ring may have a pin mounting portion 117 with a first mounting hole 118 at approximately the middle, thereby allowing the pull ring 11 to be mounted by means of the pin 3 (see...). Figure 6 It is installed in the pull ring seat 12 and can rotate about the pin 3 relative to the pull ring seat 12 to meet different usage requirements.

[0039] Figure 4 The structure of the pull ring seat 12 of the pull ring assembly 1 according to the first embodiment is schematically shown. Figure 4 As shown, the pull ring seat 12 may include a seat skirt 121 and a seat sleeve 122, wherein the seat skirt 121 is adapted to be mounted on the upper surface 21 of the cover plate 2 and thus visible, while the seat sleeve 122 is adapted to be located in a groove 23 of the cover plate 2 and thus invisible. It is understood that the length of the groove 23 of the cover plate 2 is slightly greater than or substantially equal to the length of the seat sleeve 122, and the depth of the groove 23 is greater than the height of the seat sleeve 122, such that the seat sleeve 122 can be completely located within the groove 23 without being exposed.

[0040] See Figure 4 and Figure 5 The seat skirt 121 can be configured to have a small thickness, such that when the pull ring seat 12 is fixed to the cover plate 2, the upper surface 125 of the seat skirt 121 does not extend excessively beyond the upper surface 21 of the cover plate 2 (see...). Figure 1 The upper surface 21 of the cover plate 2 is designed to be as flat as possible; while the seat sleeve 122 is constructed to have a greater height to ensure installation stability. It is understood that the thickness of the seat skirt 121 and the height of the seat sleeve 122 both extend in the vertical direction Y.

[0041] See Figure 4The seat sleeve 122 may include seat fastening portions 123 located on both sides and a pull ring receiving cavity 124 located in the middle, that is, the pull ring receiving cavity 124 is located between the two seat fastening portions 123. The seat fastening portions 123 may have fastener mounting holes to fix the pull ring seat 12 to the cover plate 2 by means of fasteners. The pull ring receiving cavity 124 may be configured to have a vertically through structure, such that the pull ring receiving cavity 124 has an upper opening and a lower opening. It is understood that the upper opening of the pull ring receiving cavity 124 is arranged on the same side as the upper surface 21 of the cover plate 2. The seat skirt 121 may be configured to be arranged around the upper opening of the pull ring receiving cavity 124. The pull ring receiving cavity 124 has two opposite sidewalls with a second mounting hole 127 at approximately the midpoint, corresponding to the first mounting hole 118 of the pull ring bottom 112, so as to install the pull ring bottom 112 into the pull ring receiving cavity 124 by means of the pin 3, allowing the pull ring 11 to rotate relative to the pull ring seat 12 about the pin 3 within the pull ring receiving cavity 124. It is understood that the opening length of the pull ring receiving cavity 124 is substantially equal to or slightly greater than the length of the pull ring bottom 112, so that the pull ring 11 can rotate smoothly within the pull ring receiving cavity 124.

[0042] Figure 6 The diagram shows a pull ring 11 mounted in a pull ring seat 12 and rotated by an angle relative to the seat 12, i.e., the pull ring 11 is in a position between an exposed position and a concealed position. It is understood that the rotation angle required for the pull ring 11 to move from the exposed position to the concealed position or from the concealed position to the exposed position is 180°. That is, a rotational travel of the pull ring 11 exceeding 180° (e.g., when the user applies excessive force) will be detrimental to the user's operation of the pull ring 11, because the pull ring 11 will wobble back and forth within the seat 12, making it difficult for the user to grip the pull ring 11. Therefore, in some embodiments, the edge of the handle 111 has a [feature] on only one side... Figure 2 The stop portion 115 shown is, by way of example, as Figure 3 As shown, the stop 115 can be configured as a boss protruding from the edge of the handle 111, correspondingly, as... Figure 5 As shown, the inner wall of the pull ring receiving cavity 124 has recesses 126 on each of its respective opposite sides for engaging with the boss. In this embodiment, the recesses 126 are configured as vertical grooves along the vertical direction Y, which are recessed inward from the inner wall of the pull ring receiving cavity 124, and the upper part of the vertical groove is a certain distance away from the upper opening edge of the pull ring receiving cavity 124 (i.e., the upper part of the vertical groove is not connected to the upper opening of the pull ring receiving cavity 124), such that a step for stopping is formed at the upper part of the vertical groove, while the distance between the lower part of the vertical groove and the lower opening edge of the pull ring receiving cavity 124 is 0, such that the lower part of the vertical groove is connected to the lower opening.

[0043] Figure 7This is a cross-sectional view of the assembled pull ring 11 and pull ring seat 12. When the rotation stroke of the pull ring 11 is 180°, the pull ring 11 rotates from the hidden position to the exposed position or from the exposed position to the hidden position. At this time, as... Figure 7 As shown, the stop 115 engages in the recess 126. Due to the stopping effect of the step on the upper part of the recess 126, the pull ring 11 cannot rotate further, thus remaining in the hidden or exposed position without wobbling back and forth. And since the recess 126 communicates with the lower opening at the bottom, it allows a 180° downward rotation from the current position (hidden or exposed position) to switch to another position (exposed or hidden position).

[0044] See you again Figure 1 In the assembly diagram shown, in some embodiments, the upper surface 125 of the seat skirt 121 can be configured as an inwardly curved arc surface. It is understood that the curvature of the upper surface 125 of the seat skirt 121 is small, resulting in only a slight arc, causing the inner portion of the upper surface 125 of the seat skirt 121 to slope slightly downward relative to the outer portion. The middle portion of the lower surface 116 of the pull ring bottom 112 can be configured to protrude slightly outward relative to the two side portions. This structural design of the upper surface 125 of the seat skirt 121 and the lower surface 116 of the pull ring bottom 112 improves the user's tactile experience, facilitating the rotation of the pull ring 11 from the pull ring seat 12, and enhances the overall design aesthetics of the visible surfaces.

[0045] Figure 8 The pull ring assembly 1 according to Embodiment 2 of this application is shown fixed to the cover plate 2. The only difference from the pull ring assembly of the first embodiment is that, in addition to the pull ring 11 and pull ring seat 12, the pull ring assembly of Embodiment 2 also includes a cover 13 adapted to be located below the pull ring seat 12 and disposed on the lower surface 22 of the cover plate 2. The above-described embodiments of the pull ring 11 and pull ring seat 12 of the pull ring assembly of Embodiment 1 are all applicable to the pull ring 11 and pull ring seat 12 of the pull ring assembly of Embodiment 2; therefore, the specific structures of the pull ring 11 and pull ring seat 12 will not be described in detail here.

[0046] On the one hand, for a relatively thin cover plate 2, a stable installation can be achieved simply by fixing the pull ring seat 12 to the cover plate 2. However, for a relatively thick cover plate 2, it is preferable to use an additional cover 13 together with the pull ring seat 12 to install the pull ring 11, so as to ensure the stability of the installation. On the other hand, the upper and lower openings of the groove 23 of the cover plate 2 may have burrs or sharp edges. Since the pull ring seat 12 is arranged on the upper surface 21 of the cover plate 2, the upper opening of the groove 23 can be covered by the pull ring seat 12, so it will not cause any adverse effects. However, without the cover 13, the lower opening of the groove 23 will be completely exposed, and the burrs or sharp edges on it may pose a safety hazard. Therefore, based on this, regardless of whether the cover plate 2 is relatively thick or relatively thin, an additional cover 13 can be used to cover the lower opening of the groove 23 of the cover plate 2, thereby improving aesthetics and safety in use.

[0047] like Figure 8 As shown, the cover 13 may have a cover fastening part 131 corresponding to the seat fastening part 123 and a cover opening 132 corresponding to the pull ring receiving cavity 124. Figure 9 and Figure 10 Two examples of cover components with different structures are shown.

[0048] See Figure 9 Figures (a) and (b) show the structure of the cover 13 according to the same embodiment from different perspectives. In this embodiment, similar to the pull ring seat 12, the cover 13 may include a cover skirt 133 and a cover sleeve 134 extending vertically from the cover skirt 133. The cover skirt 133 has cover fastening portions 131 on both sides, which may have through holes for engaging with fasteners. It is understood that the position and size of the through holes of the cover fastening portions 131 are adapted to the fastener mounting holes of the seat fastening portions 123. The cover sleeve 134 is configured to be vertically through, thereby forming a cover opening 132. The cover skirt 133 is arranged around the cover opening 132, and the cover sleeve 134 extends in the vertical direction Y. It is understood that the position and size of the opening of the cover sleeve 134 are adapted to the opening of the pull ring receiving cavity 124. In this embodiment, the cover skirt 133 is configured to have a thinner thickness, while the cover sleeve 134 is configured to have a larger height.

[0049] See Figure 8The assembly diagram shown illustrates that the cover skirt 133 is fitted to the lower surface 22 of the cover plate 2, the cover sleeve 134 is located in the groove 23 of the cover plate 2, the through hole of the cover fastener 131 is aligned with the fastener mounting hole of the seat fastener 123, and the opening of the cover sleeve 134 is aligned with the opening of the pull ring receiving cavity 124. Both the pull ring receiving cavity 124 and the cover sleeve 134 extend in the depth direction (i.e., the vertical direction Y) of the groove 23. It can be understood that the sum of the heights of the pull ring receiving cavity 124 and the cover sleeve 134 is less than the depth of the groove 23. It should be noted that, due to… Figure 9 The cover 13 in the illustrated embodiment has a relatively tall cover sleeve 134, so such a cover 13 is more suitable for situations where the cover plate 2 has a relatively thick thickness, in order to maintain the stability of the installation.

[0050] See Figure 10 In this embodiment of the cover, the cover 13 is constructed as a generally flat plate with a relatively thin thickness. The cover 13 may have cover fasteners 131 on both sides and a cover opening 132 in the middle that penetrates the upper and lower surfaces of the cover.

[0051] The pull ring 11 and pull ring seat 12 of the pull ring kit according to the first embodiment, and the pull ring 11, pull ring seat 12, and cover 13 of the pull ring kit according to the second embodiment, can each be integrally molded from a plastic material, such as modified nylon, using an injection molding process. In contrast, if the above-mentioned components are made of metal, they typically require initial molding through a casting process, followed by machining to refine the shape, and finally spraying to give the components the desired color. The entire manufacturing process involves many steps and is quite cumbersome, resulting in low efficiency. However, if the injection molding process described in this embodiment is used, components with regular shapes and smooth edges can be obtained directly without further machining. Moreover, if a desired color is desired, simply adding appropriate components to the plastic composition can directly produce components with the corresponding color without further spraying. This greatly simplifies the production process, improves production efficiency, and is suitable for mass production. In addition, compared to metal parts, plastic parts can have smoother contours, thus improving the user's tactile experience and enhancing aesthetics. Moreover, in cold environments, plastic parts provide a gentler touch (i.e., not cold to the touch) compared to metal parts, resulting in a better user experience.

[0052] The pull ring kit according to an embodiment of this application includes a pull ring and a pull ring seat mounted together. The pull ring is rotatable relative to the pull ring seat to switch between an exposed position and a concealed position. With this structural design, when it is necessary to open the cover, the user can rotate the pull ring to the exposed position to open the cover by means of the pull ring; when it is not necessary to open the cover, the pull ring is concealed and does not protrude from the cover, thus eliminating safety hazards and preserving aesthetics.

[0053] The pull ring kit according to an embodiment of this application also includes a cover, which is disposed on the lower surface of the cover plate to cover the lower opening of the groove of the cover plate, thereby improving safety and aesthetics, and also improving the stability of the pull ring installation.

[0054] Furthermore, the pull ring also has a reinforcing part including a weight-reducing section, so that the pull ring has high strength while being lightweight.

[0055] In addition, the pull ring has a stop on its side. By cooperating with the recess of the pull ring seat, the rotation stroke of the pull ring is limited to within 180°, preventing the pull ring from wobbling up and down, so that the user can grip the pull ring.

[0056] In addition, the upper surface of the skirt of the pull ring seat is constructed as an inwardly curved arc surface, and the middle part of the lower surface of the bottom of the pull ring is constructed to protrude outward relative to its two sides. This structural design can improve the user's tactile feel, making it easier for them to rotate the pull ring out of the pull ring seat, and enhance the overall design of the visible surface.

[0057] On the other hand, embodiments of this application also provide a cover plate, which may be, for example, a basement cover plate, a tatami cover plate, or a door or window suitable for installing a concealed handle. The cover plate may be provided with a pull ring kit as described in any of the above embodiments or any combination of embodiments. Furthermore, the cover plate may have a groove for installing the pull ring kit.

[0058] In another aspect, embodiments of this application also provide an appliance, such as a tatami mat, which includes the cover plate described in the above embodiments.

[0059] Exemplary embodiments of the pull ring kit according to the present invention have been described in detail herein; however, it should be understood that the present invention is not limited to the specific embodiments described and shown above. Various modifications and variations can be made to the present invention by those skilled in the art without departing from its spirit and scope. All such modifications and variations fall within the scope of the present invention. Moreover, all components described herein can be replaced by other technically equivalent components.
