Description
Technical Field
[0001] The utility model relates to the field of furniture, in particular to a sofa with an improved installation mode. Background Art
[0002] As one of the common furniture, sofas are often placed somewhere in the room. Due to their relatively large size and weight, as well as the characteristics that are not conducive to movement, people do not move them often, which causes dust to easily accumulate at the bottom of the sofa and is difficult to clean, causing great trouble for cleaning.
[0003] With the improvement of living standards, people will also use sweeping robots to clean the floor of their houses. The existing electric sofas are too low from the ground, which limits the work of sweeping robots. Therefore, sofas with high-leg functions have been developed. However, the high-leg sofas currently on the market do not have truly high legs because they are limited by the weight of the mechanical extension mechanism. If the sofa structure is to meet sufficient requirements, additional supporting legs and other structures need to be added under the sofa. Therefore, the mechanical extension device originally designed for high legs loses its function of increasing the ground clearance, making it easy for dirt to accumulate under the seat and difficult to clean. In addition, because the load-bearing legs are added under the seat and its wooden frame is exposed, it looks bloated, which affects the overall appearance.
[0004] In multi-seater sofas, due to the long length of such sofas, additional support legs need to be added in the middle, further hindering the work of the sweeping robot; in addition, due to the existing installation mode of the mechanical extension device and the sofa armrests and the heavy weight of the mechanical extension device, in a multi-seater sofa, if two or more movable seats are to be set up, that is, two or more mechanical extension devices are to be set up, additional support parts such as armrests must be added to support the mechanical extension devices. Summary of the Invention
[0005] In order to solve the above-mentioned technical problems, the utility model provides a sofa with an improved installation mode, including a support frame, a mechanical extension device and two armrest members, the mechanical extension device is installed on the support frame, and the support frame is installed on the armrest members; the support frame includes at least two load-bearing members, the load-bearing members are arranged between the two armrest members in the left and right directions, and the load-bearing members lift the mechanical extension device above them in the front and back directions, so that there is no need to set support feet under the load-bearing members and the mechanical extension device; the support frame is used to reinforce the structure and increase the load-bearing capacity. After the armrest members on both sides are connected by the support frame, the overall structure is more stable and firm. Without reducing the ground clearance, the mechanical extension device is stably installed on the load-bearing members, the strength of the installation structure is guaranteed, and there is no need to set additional support feet under the mechanical extension device for load-bearing, and the load-bearing members will not cause the mechanical extension device to protrude downward to the height of the support feet, so the ground clearance will not be reduced, and a true high leg is achieved; at the same time, there is no need to add armrests and support feet in the middle of a multi-seat sofa.
[0006] The technical solution of the present utility model is achieved as follows:
[0007] A sofa with an improved installation mode includes a support frame, at least one mechanical extension device and two armrest members located on both sides of the mechanical extension device, the support frame includes at least two load-bearing members, the two load-bearing members are distributed in the front-to-back direction, the load-bearing member is arranged between the two armrest members in the left-to-right direction, and the two ends of the load-bearing member are respectively fixedly connected to the two armrest members; the mechanical extension device is installed above the load-bearing member, the load-bearing member is configured to support the mechanical extension device and keep the mechanical extension device above the load-bearing member, and the load-bearing member and the mechanical extension device are both in a suspended state relative to the ground.
[0008] The support frame is used to strengthen the structure and increase the load-bearing capacity. After the armrests on both sides are connected through the support frame, the overall structure is more stable and firm. Without reducing the ground clearance, the mechanical extension device is stably installed on the load-bearing parts, and the strength of the installation structure is guaranteed. There is no need to set additional supporting feet under the mechanical extension device for load-bearing, and the load-bearing parts will not cause the mechanical extension device to protrude downward to the height of the supporting feet, so the ground clearance will not be reduced, and a true high foot is achieved.
[0009] Since the mechanical extension device does not protrude downward from the load-bearing part, the height of the load-bearing part is the ground clearance of the sofa. The effect of real high legs can be easily achieved by simply increasing the height of the load-bearing part appropriately. The purpose of high legs is not that the higher the better. The appropriate height can not only meet the comfort of the human body when sitting or lying, but also allow the sweeping robot to move unobstructed.
[0010] After improving the installation mode through the above solution, there is no need to add additional support legs in the middle of a multi-seat sofa to facilitate the operation of the sweeping robot; in the case of multiple movable seats, there is no need to add armrests to support the mechanical extension device.
[0011] Preferably, the support frame further includes a connector fixedly connected to the load-bearing member; the connector is disposed along the length of the armrest member and is fixedly connected to the armrest member. The connector serves to connect the load-bearing member and the armrest member. The load-bearing member is not directly connected to the armrest member because the strength of the connection between the two end surfaces of the load-bearing member and the armrest member alone cannot meet the required requirements. The seemingly redundant connector can increase the connection area or connection points with the armrest member, thereby increasing the strength of the connection and ensuring stable support for the mechanical extension device and the human body.
[0012] Preferably, the length of the connector is 70%-90% of the length of the armrest. A longer connector will also extend the overlap with the armrest, allowing for more connection points to enhance connection stability, increase overall load-bearing capacity, and ensure true high legs.
[0013] Preferably, the connector includes a stabilizing portion that protrudes upward from the connector, with the upper end of the stabilizing portion fixedly connected to the armrest. The purpose of adding the stabilizing portion is to expand the connector's height connection points, thereby preventing the connector from being subjected to severe inward shear forces due to the connection points being at similar heights. The connection between the stabilizing portion and the armrest is such that, after the armrest is connected, the overall force applied to the connecting screws is more balanced and reasonable, thereby increasing the stability and strength of the connection.
[0014] As an advantage, the stabilizing portion is located at the front end of the connector. Such a connector has a simple structure and is easy to produce.
[0015] Preferably, the end of the load-bearing member is provided with a plug-in portion, and the connector is provided with a corresponding slot. The plug-in portion is inserted into the slot and fixedly connected to the load-bearing member and the plug-in portion by screws. This plug-and-lock connection method makes the connection between the load-bearing member and the connector more diverse, and makes the connection force as rational as possible, thereby ensuring a stable connection between the load-bearing member and the connector.
[0016] Preferably, the plug-in portion includes at least two symmetrically arranged plugs, which are plugged into the slots to make the force applied to the load-bearing member and the connecting member more reasonable after the connection.
[0017] Preferably, the load-bearing member and the connecting member are fixed by welding.
[0018] Preferably, support legs are installed beneath the armrests, one in front and one behind. These legs are vertical columns that provide support for the main body of the sofa. These vertical columns significantly open up the area beneath the sofa, allowing the robot vacuum to enter and exit. Furthermore, conventionally sized support legs can achieve true height support, providing simplicity and convenience.
[0019] As an advantage, the lower end of the armrest is in contact with the ground, and the armrest is configured to support the main body of the sofa. The armrest can also be directly placed on the ground.
[0020] Preferably, the load-bearing member is a strip-shaped plate or pipe. The load-bearing member is used to bear weight and requires a certain strength. At the same time, in order to support the mechanical extension device, the load-bearing member also needs to be long enough, so the load-bearing member is in a long strip shape.
[0021] The design starting point, concept and beneficial effects of the utility model using the above technical solution are:
[0022] 1. The support frame is used to reinforce the structure and increase the load-bearing capacity. After the armrests on both sides are connected by the support frame, the overall structure is more stable and firm. Without reducing the ground clearance, the mechanical extension device is stably installed on the load-bearing member, ensuring the strength of the installation structure. No additional support feet are required for load-bearing. The load-bearing member will not cause the mechanical extension device to protrude downward to the height of the support feet, thus not reducing the ground clearance, thus achieving a true high leg. Because the mechanical extension device does not protrude downward from the load-bearing member, the height of the load-bearing member, or the length of the support foot, is the ground clearance of the sofa. Simply increasing the length of the support foot can easily achieve the effect of a true high leg. The purpose of high legs is not to be as high as possible. The appropriate height can not only meet the comfort of the human body when sitting or lying down, but also allow the sweeping robot to move unimpeded.
[0023] 2. The connectors serve to connect the load-bearing components to the handrails. The load-bearing components are not directly connected to the handrails, as the strength of the connection between the two end surfaces of the load-bearing components and the handrails alone would not meet the required requirements. The seemingly redundant connectors increase the connection area or connection points with the handrails, thereby increasing the strength of the connection and ensuring stable support for the mechanical extension device and the human body. The longer the connectors, the longer the overlap with the handrails. The increased number of connection points can enhance connection stability, increase the overall load-bearing capacity, and ensure the realization of true high legs.
[0024] 3. The purpose of adding the stabilizing part is to expand the connection points of the connector in the height direction, so that the connector will not be subjected to severe inward shear force due to the connection points being at similar heights. The connection between the stabilizing part and the handrail is that after the handrail is connected, the overall force of the screws used for connection is more balanced and reasonable, thereby increasing the stability and strength of the connection.
[0025] 4. After improving the installation mode through the above solution, there is no need to add additional support feet in the middle of the multi-seater sofa to facilitate the operation of the sweeping robot; in the case of multiple movable seats, there is no need to add armrests to support the mechanical extension device.

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0041] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise explicitly defined. The terms "first," "second," "third," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.
[0042] The specific implementation of the utility model is as follows: Example
[0043] like Figure 1 、 2 As shown in Figure 8, the utility model provides a sofa with an improved installation mode, comprising a support frame 1, at least one mechanical extension device 2 and armrests 3 located on both sides of the mechanical extension device 2, the support frame 1 comprising at least two load-bearing members 11, the two load-bearing members 11 are distributed in the front-to-back direction, the load-bearing member 11 is arranged between the two armrests 3 in the left-right direction, and the two ends of the load-bearing member 11 are fixedly connected to the two armrests 3 respectively; the mechanical extension device 2 is installed above the load-bearing member 11, the load-bearing member 11 is configured to support the mechanical extension device 2 and keep the mechanical extension device 2 above the load-bearing member 11, and the load-bearing member 11 and the mechanical extension device 2 are both in a suspended state relative to the ground; a support foot 7 is installed below the armrest 3, and the support foot 7 is configured to support the main body of the sofa.
[0044] The support frame 1 is used to reinforce the structure and increase the load-bearing capacity. After the armrests 3 on both sides are connected through the support frame 1, the overall structure is more stable and firm. Without reducing the ground clearance, the mechanical extension device 2 is stably installed on the load-bearing member 11, and the strength of the installation structure is guaranteed. No additional support feet 7 are required for load-bearing, and the load-bearing member 11 will not cause the mechanical extension device 2 to protrude downward to the height of the support feet 7, so the ground clearance will not be reduced, and a true high leg is achieved.
[0045] Since the mechanical extension device 2 does not protrude downward from the load-bearing part 11, the height of the load-bearing part 11 or the length of the supporting foot 7 is the ground clearance of the sofa. The effect of truly high feet can be easily achieved by simply increasing the length of the supporting foot 7 appropriately. The purpose of high feet is not to make them as high as possible. An appropriate height can not only satisfy the comfort of the human body when sitting or lying down, but also allow the sweeping robot to move freely.
[0046] After improving the installation mode through the above solution, there is no need to add additional support legs in the middle of a multi-seat sofa to facilitate the operation of the sweeping robot; in the case of multiple movable seats, there is no need to add armrests to support the mechanical extension device.
[0047] Of course, the armrests can also be placed directly on the ground to serve as the main support of the sofa.
[0048] Specifically, if Figure 3 、 4 As shown, in this embodiment, there are two load-bearing members 11, and the two load-bearing members 11 are arranged between the two armrest members 3, one load-bearing member 11 is located at the rear end of the armrest member 3, and the other load-bearing member 11 is located in the middle of the armrest member 3; the support frame 1 also includes a connecting member 12, and there are two connecting members 12, which are located on both sides of the load-bearing member 11, and the connecting member 12 is fixedly connected to the load-bearing member 11; further, a plug-in portion is provided at the end of the load-bearing member 11, and the plug-in portion includes at least two symmetrically arranged plug-ins 4, and a slot 5 is correspondingly provided on the connecting member 12. The symmetrically arranged plug-ins 4 are plugged into the slot 5, and the load-bearing member 11 is fixedly connected to the plug-in portion by screws; through this connection method of locking after plugging, the connection between the load-bearing member 11 and the connecting member 12 is more diversified, and the connection force is rationalized as much as possible, thereby ensuring a stable connection between the load-bearing member 11 and the connecting member 12.
[0049] The load-bearing member 11 is a round tube, and the connecting member 12 is a plate. The load-bearing member 11 can be selected to have an appropriate length according to whether it is a single sofa or a multi-person sofa to adapt to different sofa sizes; the load-bearing member 11 and the connecting member 12 can of course also be fixedly connected by welding, but in order to have more reasonable force and stronger structural stability, this embodiment chooses the above solution; the load-bearing member 11 and the connecting member 12 are connected to form a rectangular frame, that is, the general shape of the support frame 1 is a rectangle.
[0050] Furthermore, if Figure 5As shown, the connecting member 12 is arranged along the length direction of the armrest member 3 and is fixedly connected to the armrest member 3. The length of the connecting member 12 accounts for 70%-90% of the length of the armrest member 3. In this embodiment, the length of the connecting member 12 accounts for 88% of the length of the armrest member 3. The length of the connecting member 12 is longer, and the part overlapping with the armrest member 3 is also longer. The connection points can be appropriately increased, thereby enhancing the connection stability, increasing the overall load-bearing capacity, and ensuring the realization of true high feet; wherein, the function of the connecting member 12 is to connect the load-bearing member 11 and the armrest member 3. The load-bearing member 11 is not directly connected to the armrest member 3, because the strength of the connection between the two end faces of the load-bearing member 11 and the armrest member 3 cannot meet the required requirements, and the connecting member 12 seems to be more but can increase the connection area or connection points with the armrest member 3, thereby increasing the strength of the connection and ensuring stable support for the mechanical extension device 2 and the human body.
[0051] The connecting piece 12 is roughly L-shaped, and the connecting piece 12 includes a stabilizing portion 6. The stabilizing portion 6 is located at the front end of the connecting piece 12, and the stabilizing portion 6 protrudes upward from the connecting piece 12. The upper end of the stabilizing portion 6 is fixedly connected to the armrest piece 3; the purpose of adding the stabilizing portion 6 is to expand the connection point of the connecting piece 12 in the height direction, and will not be subjected to severe inward shear force due to the connection points being at similar heights. The connection between the stabilizing portion 6 and the armrest piece 3 is that after the armrest piece 3 is connected, the overall force of the screws used for connection is more balanced and reasonable, thereby increasing the stability and strength of the connection.
[0052] The connecting member 12 is fixedly connected to the armrest member 3 by screws. There are four connection points between the connecting member 12 and the armrest member 3, namely the upper end of the stabilizing portion 6, the front and rear ends of the connecting member 12, and the middle part of the connecting member 12. The connection point at the upper end of the stabilizing portion 6 is the highest, and the connection point in the middle of the connecting member 12 is slightly higher than the connection points at the front and rear ends of the connecting member 12. The connection points set in this way make the force more reasonable and the connection stability and strength better.
[0053] A support foot 7 is provided at the front and rear under the armrest 3, with a total of four support feet distributed at the four corners of the bottom of the sofa. The support feet 7 are the same as the support feet 7 of a conventional sofa. The support feet 7 are vertically arranged columns, which open up the bottom of the sofa to a great extent for the sweeping robot to enter and exit. On the other hand, there is no need to add external support parts other than the support feet 7, and the structure is simple.
[0054] like Figure 6 、 7As shown, the left and right sides of the mechanical stretching device 2 have side panels 21 for connecting the load-bearing member 11, and the side panels 21 are each provided with an accommodating space, and the load-bearing member 11 is located in the accommodating space; the accommodating space is provided with a mounting plate 22 extending horizontally toward the center of the mechanical stretching device 2, and the mounting plate 22 is fixedly connected to the load-bearing member 11 by screws, and the screws pass through the mounting plate 22 on the lower right web of the load-bearing member 11 to lock the two; the accommodating space corresponding to the load-bearing member located in the middle of the armrest member 3 is a groove 8, and the accommodating space corresponding to the load-bearing member located at the rear of the armrest member 3 is a notch 9.
[0055] Embodiment 2: The only difference between this embodiment and embodiment 1 is that two mechanical stretching devices are provided on a single supporting frame.
[0056] like Figure 9-12 As shown, the sofa is a multi-seat sofa and a multi-movable seat sofa, that is, it has two mechanical extension devices 2, both of which can move independently, and the two mechanical extension devices 2 are arranged on a single support frame 1, and the single support frame 1 is only connected to the armrests 3 on both sides and supported by the support feet 7 under the two armrests 3.
