Description

Technical Field

[0001] The utility model is a reinforcement component for a functional sofa, in particular to a reinforcement device for the overall structure of the functional sofa, belonging to the technical field of sofas. Background Art

[0002] Functional sofas refer to sofas with multiple functions. The most common functional sofas nowadays mainly include two types: one is a manual function extension, which can be shaken or rotated; the other is an electric function extension, which can also achieve the two functions of shaking and rotating. The functional structure of a functional sofa mainly includes the sofa body (including seats, backrests and armrests) and functional frames. The seat is the basic part of the functional sofa, which bears the weight of the entire sofa and provides stable support.

[0003] Usually, the functional frame of a functional sofa is installed under the seat and connected to the two side walls of the sofa body (that is, it can be the two opposite side walls of the sofa armrests, or the inner walls of the two side panels under the seat). The two side walls of the sofa body support the functional frame and also bear the lateral or longitudinal tension and pressure generated during the operation of the functional frame. These tensions and pressures mainly act on the connection positions of the two side walls of the sofa body. In a short period of time, no harm may be seen by the naked eye. However, after long-term use, under the continuous action of the above-mentioned lateral or longitudinal tension and pressure, the two side walls of the sofa body will deform, crack, or even break, which will directly affect the service life of the functional sofa. Therefore, when selling functional sofas, manufacturers of functional sofas on the market will remind users to perform regular maintenance and upkeep. On the surface, this is to provide users with better after-sales service. The fundamental reason is to timely discover the deformation and damage (such as cracks and fragmentation) of the sofa armrests and U-shaped reinforcement frames during use during daily maintenance and upkeep, so as to timely reinforce or replace the relevant components to avoid the loss of support and working ability of the functional frame caused by damage to the U-shaped reinforcement frame. Compared with ordinary sofas, the price of functional sofas is generally more expensive. Once the functional frame loses support and loses working ability, its value based on functionality will disappear, and it may even cause the two sides of the sofa body to collapse, making the sofa directly unusable. For consumers, the occurrence of these situations means that the huge expenditure of purchasing functional sofas is wasted, which directly affects consumers' satisfaction with functional sofas and their manufacturers, and even makes consumers lose confidence in manufacturers and have a sense of distrust. The brand reputation of manufacturers may also be reduced, affecting the subsequent operation and development of manufacturers.

[0004] Compared with ordinary sofas, various existing functional sofas have more complex functional frames added to their internal structures. The functionality of the functional sofas depends on the mechanical movement of the functional frames, and the strength of the supporting structures formed by the functional frames inside many functional sofas cannot meet the needs of the functional frames working for a long time. Therefore, these functional sofas generally have the problem of short service life, and the existing reinforcement brackets or reinforcement structures have not yet achieved a relatively ideal technical effect in solving the above problems.

[0005] For example, the utility model patent with application number CN201520758998.1 discloses a reinforcement structure of a sofa, including a reinforcement edge protruding downward from the bottom edge of the sofa body, the reinforcement edge forming an annular closed portion, and the reinforcement structure also includes a plurality of rod-shaped connecting rods, the connecting rods are located in the closed portion and form a reinforcement portion for increasing the bottom strength of the body. This patent only increases the bottom strength of the body, but does not increase the overall strength of the body.

[0006] Another example: the utility model patent with application number CN202220926722.X discloses a functional sofa load-bearing bracket, in which the reinforcing plate connected to the cushion mounting plate or the main board through the fixed hole position must form a triangular structure with the load-bearing bracket, the cushion mounting plate or the main board, thereby effectively enhancing the structural stability of the load-bearing bracket; at the same time, since the first mounting hole is set on the front side of the cushion mounting plate and the second mounting hole is set on the back side of the main board, the load-bearing bracket can be effectively prevented from shifting in the vertical direction. Its main function is to enhance the structural stability of the load-bearing bracket, but it does not improve the stability of the sofa functional frame during use.

[0007] In summary, the prior art does not provide effective solutions to the above and related problems. Utility Model Content

[0008] The utility model aims to form a more stable overall reinforcement structure by arranging a U-shaped reinforcement frame for installing a functional frame and a U-shaped reinforcement piece arranged in the same direction as the U-shaped reinforcement frame under the seat of the sofa body, and replacing the inner wall of the sofa body with the functional frame by the U-shaped reinforcement frame to connect, so that the connection area is increased and the unit load is reduced. At the same time, the overall reinforcement structure formed by the U-shaped reinforcement piece and the U-shaped reinforcement frame makes the supporting structure of the sofa body sufficient to resist the lateral or longitudinal tension and pressure generated during the working process of the functional frame; thereby avoiding the direct connection between the sofa body and the functional frame, effectively reducing the destructive force directly caused by the lateral or longitudinal tension and pressure generated during the working process of the functional frame on the sofa body, thereby effectively solving the problems of easy deformation and damage of the connection position of the existing functional sofa and the short service life.

[0009] The utility model is realized by the following technical solutions:

[0010] A reinforcement component for a functional sofa comprises a U-shaped reinforcement frame for installing a functional frame and a U-shaped reinforcement piece arranged in the same direction thereof, wherein the U-shaped reinforcement frame is arranged below a seat of a sofa body, and its two side panels are respectively fixed to the two side walls of the sofa body, and a rear panel is fixed to the rear wall of the sofa body, and two arms of the U-shaped reinforcement piece are fixedly arranged along the inner wall of the U-shaped reinforcement frame, and the ends of the two arms are provided with bending portions extending upward along the inner wall of the U-shaped reinforcement frame, and the bow portion of the U-shaped reinforcement piece is fixed to the rear wall of the U-shaped reinforcement frame or arranged close to the rear wall of the U-shaped reinforcement frame.

[0017] Preferably, the two ends of the cross bar and the two arms of the U-shaped reinforcement are cooperated with a limiting device for limiting the rest position of the cross bar.

[0019] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0020] (1) The utility model provides a U-shaped reinforcement frame for mounting a functional frame and a U-shaped reinforcement piece provided in the same direction under the seat of the sofa body, and provides bent portions raised along the outer ends of the U-shaped reinforcement frame at the ends of the two arms of the U-shaped reinforcement piece, thereby realizing the lateral and longitudinal force transmission of the U-shaped reinforcement frame, so that the U-shaped reinforcement frame and the U-shaped reinforcement piece together form an integral reinforcement structure, which not only enables the force that should be applied to the inner wall of the sofa body when the functional frame is working to be transmitted, dispersed and attenuated through the integral reinforcement structure formed by the U-shaped reinforcement frame and the U-shaped reinforcement piece, thereby effectively reducing the load at the connection position of the functional frame, but also makes the integral reinforcement structure of the U-shaped reinforcement frame more stable by adding the U-shaped reinforcement piece to the U-shaped reinforcement frame, thereby increasing the support surface for resisting external forces, and effectively avoiding the occurrence of tearing and damage due to excessive local force, thereby effectively improving the problems of easy deformation and damage at the connection position of the existing functional sofa, and further extending the service life of the functional sofa.

[0021] (2) The utility model arranges the bow of the U-shaped reinforcement member perpendicular to the two arms and arranges a reinforcement plate at the angle between them, thereby making the overall reinforcement structure formed by the U-shaped reinforcement frame and the U-shaped reinforcement member (i.e., the supporting structure of the sofa body) more stable.

[0022] (3) The utility model sets the angle between the bent portion and the arm of the U-shaped reinforcement member where it is located to 90-120 degrees and sets the distance between the upper end of the bent portion and the top of the side wall of the U-shaped reinforcement frame to no more than 30% of the height of the U-shaped reinforcement frame, thereby achieving the purpose of more effectively decomposing the force generated by the functional frame when it is working to various parts of the reinforcement component through the U-shaped reinforcement member, making the overall force of the reinforcement component more uniform, avoiding damage to the U-shaped reinforcement frame, and playing a better reinforcement role on the sofa body.

[0023] (4) The utility model provides a U-shaped reinforcement member as an integrally formed solid structure, so that the force transmission performance of the U-shaped reinforcement member is better, and the ability of the reinforcement component to resist the force exerted by the functional frame on the U-shaped reinforcement frame is enhanced, thereby achieving the purpose of extending the service life of the functional sofa.

[0024] (5) The present invention provides at least three fixing holes on each of the two arms of the U-shaped reinforcement member, and at least one fixing hole on the bent portion, so that the U-shaped reinforcement member can be stably connected to the U-shaped reinforcement frame, and together form an overall reinforcement structure with better stability and more uniform force, thereby preventing the U-shaped reinforcement frame (or even the inner wall of the sofa body) from being torn or damaged due to excessive local force, thereby preventing the functional frame from losing its support.

[0025] (6) The utility model provides a cross bar between the two arms of the U-shaped reinforcement member and slides along the length direction of the two arms of the U-shaped reinforcement member, so that the reinforcement assembly can be flexibly adjusted according to the structure of different functional frames to be assembled, thereby forming an overall reinforcement structure with a variable internal structure, which meets the installation needs of different functional frames and enhances the application range of the reinforcement assembly; in addition, a reinforcement plate that slides with the cross bar is provided at the angle between the cross bar and the two arms of the U-shaped reinforcement member, which can make the reinforcement assembly more stable.

[0026] (7) The utility model provides a limit device at the two ends of the cross bar in cooperation with the two arms of the U-shaped reinforcement member to limit the rest position of the cross bar, so that the cross bar can be fixed after bypassing the running route or installation position of the functional frame, forming an overall reinforcement structure and playing a more effective reinforcement role.

[0033] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0034] Embodiment 1:

[0035] like Figures 1 to 3 As shown, this embodiment discloses a reinforcement assembly for a functional sofa, comprising a U-shaped reinforcement frame 3 for mounting a functional frame and a U-shaped reinforcement member 1 arranged in the same direction thereof;

[0036] U-shaped reinforcement frame 3: arranged under the seat of the sofa body 8, the two side panels of which are respectively fixedly arranged on the two side walls of the sofa body 8, and the rear panel is fixedly arranged on the rear wall of the sofa body 8;

[0037] U-shaped reinforcement member 1: its two arms are fixedly arranged along the inner wall of the U-shaped reinforcement frame 3, and the ends of the two arms are provided with bending portions 2 extending upward along the inner wall of the U-shaped reinforcement frame 3. The bow portion of the U-shaped reinforcement member 1 is fixedly arranged on the rear wall of the U-shaped reinforcement frame 3 or is arranged close to the rear wall of the U-shaped reinforcement frame 3. The optimal angle formed between the bow portion of the U-shaped reinforcement member 1 and the two arms is 90 degrees.

[0038] The U-shaped reinforcement frame 3 replaces the inner wall of the sofa body 8 to be connected to the functional frame, and together with the U-shaped reinforcement member 1 constitutes an overall reinforcement structure, replacing the sofa body 8 to bear the force of the functional frame, thereby making the supporting structure of the sofa body 8 more solid, and effectively protecting the sofa body 8 to prevent it from being damaged during the use of the functional frame.

[0039] The specifications and dimensions of the U-shaped reinforcement frame 3 and the U-shaped reinforcement member 1 can be set according to actual production needs and should be matched with the structure of the installed functional frame as much as possible. The main purpose is to combine the U-shaped reinforcement frame 3 and the U-shaped reinforcement member 1 to form an overall reinforcement structure without affecting the operation of the functional frame, and to bear and disperse the force exerted on the sofa body 8 by the functional frame during operation, thereby realizing the reinforcement function of the sofa body 8 and avoiding or minimizing the damage to the structure of the sofa body 8 caused by the working process of the functional frame.

[0040] This embodiment can be assembled on a functional sofa during production, or the U-shaped reinforcement member 1 in the reinforcement assembly can be separated and separately set on the formed functional sofa. The reinforcement effect achieved is more significant. At the same time, this embodiment has the advantages of simple structure, small space occupation, and easy installation, and has strong adaptability.

[0041] Furthermore, in order to achieve a better reinforcement effect, the bow of the U-shaped reinforcement member 1 is vertically arranged with the two arms, and a reinforcement plate 4 is arranged at the angle between the bow and the two arms. To avoid affecting the operation of the functional frame, the reinforcement plate 4 should be arranged away from the operation line when the functional frame is working. Experiments have shown that the reinforcement plate 4 of a right-angled triangle structure is arranged at the outer angle where the bow of the U-shaped reinforcement member 1 intersects with the two arms, and the two right-angled sides of the reinforcement plate 4 are fixedly connected to the two sides of the angle, and the reinforcement performance is better.

[0042] Furthermore, in order to make the overall reinforcement structure formed by this embodiment more stable, at least three fixing holes 5 are respectively provided on the two arms of the U-shaped reinforcement member 1, and at least one fixing hole 5 is provided on the bending portion 2. The three fixing holes 5 on the same arm cannot be arranged on the same straight line, so that the U-shaped reinforcement member 1 can be more stably fixed to the U-shaped reinforcement frame 3 and form an overall reinforcement structure. Experiments have shown that the setting of the fixing holes 5 is related to the reinforcement effect of the overall reinforcement structure formed, wherein two fixing holes 5 on each of the two arms and the bending portion are the best settings, and the distance between two adjacent fixing holes 5 should be kept between 5 and 20 cm for better reinforcement effect, wherein the best distance is 10 cm. At this time, the reinforcement plate 4 is preferably arranged below the fixing hole 5, which can not only leave more operating space for the functional frame, but also provide better force transmission and dispersion effects, and can also effectively avoid the sofa body 8 from being damaged due to excessive local force.

[0043] Furthermore, in order to make the overall force of the reinforcement component more uniform, avoid damage to the sofa body 8, and achieve a better reinforcement effect, one method is to make the bending portion 2 and the arm of the U-shaped reinforcement member 1 where it is located form an angle of 90 to 120 degrees. When the angle is 110 degrees, the reinforcement effect is the best; another method is to make the distance between the upper end of the bending portion 2 and the top of the side wall of the U-shaped reinforcement frame 3 not exceed 30% of the height of the U-shaped reinforcement frame 3, and the optimal distance is 10% of the height of the U-shaped reinforcement frame 3. The two methods can achieve different reinforcement effects when used alone or simultaneously.

[0044] Furthermore, in order to make the force transmission of the U-shaped reinforcement 1 better and strengthen the ability to resist the force applied to the sofa body 8 by the functional frame when it is working, the U-shaped reinforcement 1 used adopts an integrally formed solid structure. When the cross section of the U-shaped reinforcement 1 is a rectangle parallel to the bottom of the U-shaped reinforcement frame 3, the reinforcement degree is the best. At this time, the space below the sofa body 8 occupied by the U-shaped reinforcement 1 is smaller, and the integrally formed and solid structure setting will not affect the effect of force transmission and pressure dispersion due to loose connection, thereby preventing the sofa body 8 from being damaged by the force of the functional frame when it is working during use.

[0045] Further, such as Figure 1 (d) and Figure 2 (c) As shown in the structure, in order to adapt to the installation and operation of functional racks with different functions and structures, the bow of the U-shaped reinforcement member 1 is fixed to the rear wall of the U-shaped reinforcement frame 3, and a cross bar 6 that can slide along the length direction of the two arms of the U-shaped reinforcement member 1 is provided between the two arms of the U-shaped reinforcement member 1, and a reinforcement plate 4 is provided at the angle between the cross bar 6 and the two arms of the U-shaped reinforcement member 1, and the reinforcement plate 4 slides with the cross bar 6. When the length direction of the cross bar 6 is perpendicular to the two arms of the U-shaped reinforcement member 1, the reinforcement effect of the formed overall reinforcement structure is better, and the sliding and adjustment of the cross bar 6 on the U-shaped reinforcement member 1 will be smoother.

[0046] Regarding the method of sliding the cross bar 6 along the length direction of the two arms of the U-shaped reinforcement member 1:

[0047] like Figure 1 (d) and Figure 2 (c) As shown in the structure, in this embodiment, in order to make the cross bar 6 slide along the length direction of the two arms of the U-shaped reinforcement 1, a slide groove 7 is respectively provided on the inner walls on the opposite sides of the two arms of the U-shaped reinforcement 1, and the two slide grooves 7 on the two arms are symmetrically arranged along the length direction of the two arms of the U-shaped reinforcement 1. A sliding block is provided in the slide groove 7, and the sliding block is connected to the cross bar 6 and drives the cross bar 6 to slide in the length direction of the two arms of the U-shaped reinforcement 1.

[0048] In actual use, there are many other methods to achieve the sliding of the cross bar 6 along the length direction of the two arms of the U-shaped reinforcement 1, such as setting fixed guide rails (guide grooves or guide ridges) on the two arms of the U-shaped reinforcement 1 along the length direction of the two arms, and setting sliding members that cooperate with the guide rails at both ends of the cross bar 6 to make the cross bar 6 slide along the guide direction of the guide rails, etc. There are also various manual sliding devices, mechanical sliding devices or electric sliding devices. As long as the sliding device, sliding structure, etc. that can achieve the above-mentioned purpose are applicable to this embodiment.

[0049] In this embodiment, a temporary sliding device can also be provided to assist the cross bar 6 in sliding installation and fixing. The temporary sliding device used includes temporary guide rails provided along the two arms of the U-shaped reinforcement member 1. The two temporary guide rails on the two arms are provided with auxiliary clamps for clamping the two ends of the cross bar 6. After the auxiliary clamp drives the cross bar 6 to a limited position and fixes it, the auxiliary clamp is released and the temporary guide rail is removed to obtain the following Figure 1 (c) and Figure 2 (b) The structure of the fixing assembly and the U-shaped reinforcement member 1 shown.

[0050] Furthermore, in order to fix the cross bar 6 at the set position when it slides to the set position and form a stable overall reinforcement structure, a limiting device for limiting the stop position of the cross bar 6 is provided on the two ends of the cross bar 6 and the two arms of the U-shaped reinforcement member 1. Of course, the two side plates of the U-shaped reinforcement frame 3 can also be provided with corresponding limiting structures.

[0051] The limiting device used in this embodiment includes a first screw hole provided at the two ends of the cross bar 6, two second screw holes provided on the two arms of the U-shaped reinforcement 1 and matched with the first screw hole, and a fixing nut. The two first screw holes and the two second screw holes have equal diameters, and their axial directions are located on the same straight line, and the two first screw holes and the two second screw holes are fixed on the same straight line by the fixing nut. Of course, the two ends of the cross bar 6 can also be fixed to the two arms of the U-shaped reinforcement 1 by welding. In this embodiment, in order to achieve the purpose of fixing the cross bar 6 at a set position, there are many kinds of limiting devices that can be used, such as a clamping device, a plug-in device, an adhesive device, etc., which are all suitable for this implementation. These limiting devices belong to the prior art and will not be described here.

[0052] Note: When using the reinforcement component for the functional sofa described in this embodiment, the appropriate length, width and spacing should be selected according to the structure of the functional sofa to be installed. The reinforcement component for the functional sofa described in this embodiment is only for one seat. If it is to be used on a functional sofa with multiple seats, the reinforcement components corresponding to the number of seats should be installed in parallel according to the limited number of users.

[0053] Installation method:

[0054] Step 1: Select reinforcement components that match the sofa seat specifications (length, width, seat data, etc.) and functional frame structure;

[0055] Step 2: Separate the U-shaped reinforcement member 1 from the U-shaped reinforcement frame 3, and then install the reinforcement assembly under the seat of the sofa body 8 (fix the two side panels of the U-shaped reinforcement frame 3 to the two inner side walls of the sofa body 8 respectively, and fix the rear panel of the U-shaped reinforcement frame 3 to the rear wall of the sofa body 8, and align the bottom of the U-shaped reinforcement frame 3 with the bottom of the sofa body 8);

[0056] Step 3: Fix the functional frame on the U-shaped reinforcement frame 3, and then install the U-shaped reinforcement member 1 along the inner walls of the two side panels of the U-shaped reinforcement frame 3. The two arms, the bow and the cross bar 6 of the U-shaped reinforcement member 1 should be adaptively adjusted according to the installation position of the functional frame and the running route of the U-shaped reinforcement member 1 during operation, so that the two arms of the U-shaped reinforcement member 1 and the bending parts 2 at the ends of the two arms avoid the installation position of the functional frame, and the bow and the cross bar 6 of the U-shaped reinforcement member 1 avoid the running route of the functional frame during operation;

[0057] Step 4: Finally, fix the U-shaped reinforcement member 1 to the inner wall of the U-shaped reinforcement frame 3 through the fixing holes 5 set on the two arms of the U-shaped reinforcement member 1, and the bottom of the two arms of the U-shaped reinforcement member 1 is preferably aligned with the bottom of the U-shaped reinforcement frame 3, thereby completing the installation of the reinforcement assembly described in this embodiment.

[0058] According to the functional racks with different functions and specifications, the utility model provides the following Figure 1 The reinforcement components of the four structures shown in (a) to (d) involve Figure 2 The three types of U-shaped reinforcement members 1 shown in (a) to (c) can be selected and used according to needs, and all have better reinforcement effects.

[0059] Embodiment 2:

[0060] This embodiment discloses a functional sofa, which includes a sofa body 8 and a reinforcement component for a functional sofa as described in Example 1. The U-shaped reinforcement frame 3 is arranged under the seat of the sofa body 8, and its two side panels are respectively fixed to the two side walls of the sofa body 8, and the back panel is fixed to the back wall of the sofa body 8.

[0061] In this embodiment, the reinforcement components are directly installed and used when producing functional sofas. It is only necessary to directly select reinforcement components that match the specifications and structure (including the structure of the functional frame) of the functional sofas produced. For specific precautions and installation methods, refer to Example 1 and will not be repeated here.

[0062] If it is installed or modified on an assembled functional sofa, the functional sofa already includes a U-shaped reinforcement frame 3, or a U-shaped frame with the same or similar structure. In addition to considering the size of the sofa, it is also necessary to consider the installation position, operation line, etc. of the sofa functional frame to avoid hindering the functional use of the functional sofa.

[0063] Usage: First, the U-shaped reinforcement member 1 in the reinforcement assembly should be separated from the U-shaped reinforcement frame 3 and used separately. The U-shaped reinforcement frame 3 or the U-shaped frame of the sofa's existing functional frame can be used to replace the U-shaped reinforcement frame 3 in Example 1. Specific precautions and installation methods refer to Example 1 and will not be repeated here.

[0064] It should be noted that, although the material and thickness of the U-shaped reinforcement frame 3 and the U-shaped reinforcement member 1 in the present invention are not limited, experiments have shown that:

[0065] (1) The U-shaped reinforcement frame 3 is made of thick wood material and is not easy to be too thin. However, in special circumstances, a thinner U-shaped reinforcement frame 3 is required. It can be made of metal material that is not easy to deform to ensure its reinforcement effect.

[0066] (2) The U-shaped reinforcement member 1 is made of a metal material with relatively high toughness, and the reinforcement effect of the overall reinforcement structure formed is the best. The thickness thereof is preferably not less than 0.5 cm.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
