Technical Field

[0001] This utility model relates to the field of fireplace mantel technology, and in particular to a retractable fireplace mantel. Background Technology

[0002] The basic structure of a fireplace includes: a mantel, a fireplace mantle, and a flue. The mantel serves a decorative purpose.

[0003] As society continues to develop, the form of fireplaces has also changed, with the emergence of devices such as electric fireplaces, which represent a significant departure from traditional fireplaces. Electric fireplaces mainly consist of a decorative fireplace mantle, a simulated fireplace insert, and a heater. However, electric fireplaces are usually retrofitted or added on, and the fireplace mantle often cannot fit the available space, requiring large-scale modifications or limiting options. This low adaptability and high modification costs make them unacceptable to many users. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a retractable fireplace mantle, which solves the problem that existing fireplace mantles cannot adapt to reserved space and have low adaptability when the fireplace is added or modified.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a retractable fireplace mantle for accommodating a fireplace, set on a placement surface, comprising:

[0006] The main body includes a support frame and a main board. The main board is distributed along the horizontal plane and is set on the top of the support frame. The support frame and the main board together form an inverted L-shaped structure.

[0007] Telescopic shelves are installed on both sides of the support frame. The main body and the telescopic shelves that move along the length of the main body together form a semi-enclosed telescopic cavity. The fireplace is installed in the telescopic cavity. The telescopic shelves include a first support wall, a second support wall and a secondary shelf. The first support wall and the second support wall together form an L-shaped structure. The secondary shelf is installed on the top of the support side wall. The secondary shelf abuts against the main body. The first support wall abuts against the support frame.

[0008] A locking component is provided at least between the telescopic frame plate and the support frame to lock the relative position of the main body and the telescopic frame plate.

[0009] In one embodiment, the locking assembly includes a locking bolt, and the first support wall has a locking through hole on the side near the main body, and the support frame has an array of locking screw holes corresponding to the locking through hole.

[0010] In one embodiment, the locking screw holes are interconnected to form a locking guide groove; the locking assembly also includes a locking sleeve, which includes a fixed part and an extended part. The fixed part is disposed in the locking through hole, and the extended part is hinged to the side of the fixed part near the support frame and extends into the locking guide groove. The locking bolt is screwed into the locking sleeve to push the extended part, so that the extended part abuts against the side wall of the locking guide groove.

[0011] In one embodiment, the inner diameter of the unfolded portion gradually decreases from the end near the fixed portion to the end away from the fixed portion.

[0012] In one embodiment, the ratio of the minimum inner diameter of the unfolded portion to the diameter of the locking bolt is 1:1.01 to 1.20.

[0013] In one embodiment, at least two sets of locking components are provided.

[0014] In one embodiment, the locking component is also disposed between the secondary frame and the main board.

[0015] In one embodiment, a guide slider is also included. The guide slider is placed on the support frame, and a guide groove is provided on the secondary frame plate corresponding to the guide slider. The guide slider is fitted into the guide groove.

[0016] In one embodiment, a buffer element is provided in the guide groove. The buffer element includes a buffer plate and a buffer spring. The buffer spring is disposed between the upper and lower sides of the guide groove and the buffer plate, and the buffer spring causes the buffer plate to abut against the guide slider.

[0017] In one embodiment, the support frame and / or the first support wall have clearance openings.

[0018] The beneficial effects of this utility model are as follows: Conventional fireplace mantels are customized according to the fireplace specifications and cannot be adjusted according to actual needs. If the size is incorrect or a fireplace of a different specification is replaced later, the fireplace mantel needs to be modified or redesigned at a high cost, resulting in low adaptability. Therefore, this utility model, by setting telescopic frame plates on both sides of the main body that can reciprocate along the length of the main body, allows the size of the telescopic cavity to be changed, thereby accommodating fireplaces of different specifications and effectively improving the adaptability of this utility model.

[0019] The telescopic frame forms a three-dimensional support structure, providing stable support for the main body and ensuring the stability and reliability of the assembled fireplace mantel structure, while ensuring that the storage function of the telescopic fireplace mantel is not affected. Furthermore, the main and secondary frames form a stepped countertop, providing a staggered sense of layering while maintaining the storage area, effectively enhancing the decorative effect of this invention.

[0020] Meanwhile, this utility model provides a locking component between the main body and the telescopic frame plate, so that the telescopic frame plate can lock its relative position with the main body after it is extended or retracted, ensuring the stability and safety of the telescopic fireplace mantle provided by this utility model after installation, making this utility model highly practical.

[0032] Please refer to Figures 1 to 6 A retractable fireplace mantle for accommodating a fireplace, set on a mounting surface, comprising:

[0033] The main body 1 includes a support frame 11 and a main board 12. The main board 12 is distributed along the horizontal plane and is set on the top of the support frame 11. The support frame 11 and the main board 12 together form an inverted L-shaped structure. Telescopic frame plates 2 are set on both sides of the support frame 11. The main body 1 and the telescopic frame plates 2, which move along the length of the main body 1, together form a semi-enclosed telescopic cavity 4. The fireplace is set in the telescopic cavity 4 and includes a first support wall 22, a second support wall 23 and a secondary frame plate 21. The first support wall 22 and the second support wall 23 together form an L-shaped structure. The secondary frame plate 21 is set on the top of the support side wall. The secondary frame plate 21 abuts against the main board 12, and the first support wall 22 abuts against the support frame 11.

[0034] Locking component 3 is provided at least between the telescopic frame plate 2 and the support frame 11 to lock the relative position of the main body 1 and the telescopic frame plate 2. Specifically, locking component 3 can be a structure such as a pin or bolt, which can fix the telescopic frame plate 2 to the main body 1. Those skilled in the art can select a suitable locking component 3 as needed, without specific limitations.

[0035] In this embodiment, the locking component 3 includes a locking bolt 31, and the first support wall 22 is provided with a locking through hole 221 on the side near the main body 1. The support frame 11 is provided with an array of locking screw holes 111 corresponding to the locking through hole 221.

[0036] If the locking assembly 3 only uses a design where the locking bolt 31 corresponds to the locking screw hole 111, the relative position of the telescopic frame 2 and the main body 1 can only adapt to the preset size. If the fireplace specifications deviate from the preset size, there will be a gap between the fireplace and the telescopic cavity 4. Although this does not affect the use, it will lead to a significant decrease in the decorative effect and appearance, seriously affecting the user experience. At the same time, during installation, the user or installer needs to operate inside the telescopic cavity 4. The difficulty of aligning the locking bolt 31 with the locking screw hole 111 in the narrow space increases, which is not conducive to the user's installation. Therefore, the locking screw hole 111 is connected as a whole or replaced as a locking guide groove 112, and the locking assembly 3 is locked through the locking guide groove 112. In addition, the locking assembly 3 of this utility model also includes a locking sleeve 32. The locking sleeve 32 includes a fixing part 321 and an unfolding part 322. The fixing part 321 is disposed in the locking through hole 221, and the unfolding part 322 is hinged to the side of the fixing part 321 near the support frame 11 and extends into the locking guide groove 112. The locking bolt 31 is screwed into the locking sleeve 32 and pushes the unfolding part 322, causing the unfolding part 322 to abut against the side wall of the locking guide groove 112. In actual use, the unfolding part 322 slides along the locking guide groove 112, providing basic limiting for the telescopic frame 2 during its extension and retraction. After the telescopic frame 2 has moved to the appropriate position, the locking bolt 31 is screwed into the locking sleeve 32, and the end of the locking bolt 31 pushes the unfolding part 322, causing the unfolding part 322 to rotate relative to the fixed part 321 and abut tightly against the locking guide groove 112. The telescopic frame 2 is locked by the friction between the unfolding part 322 and the locking guide groove 112.

[0037] In this embodiment, the inner diameter of the unfolding part 322 gradually decreases from the end near the fixing part 321 to the end away from the fixing part 321. Specifically, the unfolding part 322 is a multi-segment arc-shaped wall, which forms a cylindrical structure after being enclosed. The inner diameter gradually decreases, so that after the locking bolt 31 contacts the unfolding part 322, the unfolding part 322 can unfold outward, thereby tightly abutting against the locking guide groove 112.

[0038] In this embodiment, the ratio of the minimum inner diameter of the unfolded portion 322 to the diameter of the locking bolt 31 is 1:1.01 to 1.20. This setting can prevent the unfolded portion 322 from unfolding too much, which could cause the locking guide groove 112 to be crushed. Those skilled in the art can adjust this according to the diameter of the locking bolt and the size of the locking guide groove 112, without making specific limitations.

[0039] In this embodiment, at least two sets of locking components 3 are provided. The two sets of locking components 3 are parallel to each other to form a locking surface, which prevents the angular deflection of the telescopic frame plate 2 and further ensures the stability of the telescopic fireplace mantle.

[0040] If a locking structure is only set between the support frame 11 and the first support wall 22, although locking can be achieved, the first support wall 22 is relatively long and is prone to bending during long-term use, causing the secondary frame plate 21 to shift. This results in the telescopic frame plate 2 not fitting tightly with the main body 1. Therefore, the locking component 3 is also set between the secondary frame plate 21 and the main board 12 to lock the secondary frame plate 21 and the main board 12, and the telescopic frame plate 2 and the support frame 11 respectively. Even if a single component bends, the overall alignment of the telescopic fireplace mantle can be guaranteed to be stable, ensuring that the appearance is not affected.

[0041] Although the locking sleeve 32 in the locking assembly 3 can provide some guidance, it only restricts the sliding direction of the telescopic frame plate 2 and cannot ensure that the telescopic frame plate 2 fits against the support frame 11 during the sliding process, affecting subsequent locking installation. Therefore, this utility model also includes a guide slider 113, which is placed on the support frame 11. The secondary frame plate 21 has a guide groove 211 corresponding to the guide slider 113. The guide slider 113 is fitted into the guide groove 211, preventing the telescopic frame plate 2 from falling out and ensuring the overall stability. During installation, the guide slider 113 is aligned with the guide groove 211. Specifically, the guide slider 113 can be a T-shaped slider, and the guide groove 211 can be a corresponding T-shaped groove.

[0042] With the guide slider 113 installed, a buffer element is provided inside the guide groove 211 in this embodiment. The buffer element includes a buffer plate 212 and a buffer spring 213. The buffer spring 213 is disposed between the upper and lower sides of the guide groove 211 and the buffer plate 212, and the buffer spring 213 causes the buffer plate 212 to abut against the guide slider 113. Specifically, the guide groove 211 adopts a rectangular groove, and a T-shaped cavity is formed by the buffer plate 212 and the buffer spring 213 to clamp the horizontal part of the T-shaped slider. The buffer spring 213 buffers the vibration during the sliding of the telescopic frame plate 2 and the vibration during daily use, preventing the T-shaped slider from breaking and improving the overall service life.

[0043] In this embodiment, the support frame 11 and / or the first support wall 22 are provided with clearance openings (not shown in the figure). The clearance openings can be used to avoid the fireplace structure or to set decorative patterns to improve aesthetics and practicality.

[0044] Although this document uses terms such as "main body," "support frame," and "locking screw hole" frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
