Description

Technical Field:

[0001] The utility model belongs to the field of display brackets, and particularly relates to a suspended massage cushion, especially that the walking massage mechanism can move up and down suspended relative to the support frame. Background Art:

[0002] Most of the existing massage cushions have rigid brackets. The walking massage mechanism is supported by rigid tracks and cooperates with the racks on the tracks to achieve reciprocating motion to meet the need for large-range massage. However, traditional massage cushions can neither conform to the curve of the human back nor cooperate well with chairs. For this reason, manufacturers have innovated flexible structures, such as:

[0003] CN201920284518.0 discloses a massage backrest, including a rack guide rail and a massage mechanism. Among them: the massage backrest is provided with a main frame, and both ends of the rack guide rail formed by elastic deformation material are fixed on the main frame; the massage mechanism is provided with a walking gear that can mesh with the rack guide rail and can reciprocate along the rack guide rail. Due to the elastic characteristics of the rack guide rail, the massage backrest can be leaned on softly. However, the material of the main frame is not publicly described.

[0004] The patent of CN202121506425.1 further puts forward the concept of flexibility. It discloses an adaptive flexible massage structural member and a massage cushion, including a walking mechanism and a massage mechanism installed on the walking mechanism. The walking mechanism is installed on the flexible walking strip group and can walk along the flexible walking strip group, and the flexible walking strip group can deform to match the body curve of the person being massaged. That is, the flexible massage structural member has the function of flexible bending deformation, can adapt to the use requirements of different body shapes and different scenarios, enables the massage area to be in full contact with the massage structural member, and improves the massage comfort.

[0005] The former is expressed in terms of elasticity, with two rack tracks locked on the main frame, while the latter is described in terms of flexibility, directly connecting the two flexible racks into a whole through fixing plates at both ends; regardless of the structure, the massage mechanism adopts a structure that clamps the rack to ensure reliable meshing of the gears in the massage mechanism with the rack and maintain the electrical contact between the electrodes on the massage mechanism and the electrode strips, so as to realize the self-walking of the massage mechanism, which is also a commonly used structure for such massage cushions. Summary of the Invention:

[0006] The purpose of the utility model is to design a suspended massage cushion in which the walking massage mechanism can move up and down suspended relative to the support frame and adapt to the human curve.

[0007] The technical solution of the utility model is realized as follows: A floating massage cushion, including a walking massage movement and a pair of rack rails, with the two sides of the walking massage movement clamped on the rack rails, and the rack rails form the support for the walking massage movement; characterized in that: A pair of rack rails are arranged on a middle plate, and a support frame is arranged outside the middle plate, and at least one end of the middle plate is connected to the support frame through an elastic structure.

[0008] Both ends of the middle plate are connected to the support frame through an elastic structure.

[0009] The elastic structure refers to the following: First, the middle plate and the support frame are integrally formed, and corrugations are formed at the connection part; Second, the middle plate and the support frame are separately formed, and both ends of the middle plate are suspended on the support frame through tension springs.

[0010] Both ends of the middle plate are respectively connected through two corrugations, and the width of the corrugations is between 1 cm and 2 cm, and the spacing is greater than 5 cm.

[0011] Both ends of the middle plate are respectively connected through two tension springs, and the tension springs are suspended at the four corners of the middle plate.

[0012] Anti-pinch strips are arranged at the projections of the two sides and corners of the walking massage movement on the support frame, and the anti-pinch strips can support the bottom of the walking massage movement.

[0013] The anti-pinch strips and the side frames on both sides of the support frame are integrally formed, and a stepped structure with a higher side frame and a lower anti-pinch strip is formed.

[0014] The middle plate and the support frame are formed of flexible materials.

[0015] The two ends of the anti-pinch strip and the support frame are connected by corrugations.

[0016] In the utility model, two rack rails are combined on a middle plate, and one end or both ends of the middle plate are connected to the support frame through an elastic structure, so that the middle plate carrying the walking massage movement can float up and down relative to the support frame, adapt to the change of the human body curve, and maintain a relatively constant massage force; combined with the middle plate and the support frame formed of flexible materials, it can also be attached to the backrest of the chair.

[0028] 5 - Elastic structure; 51 - Corrugation; 52 - Tension spring; Specific implementation method:

[0029] Refer to Figures 1 to 3 , the floating massage cushion includes a walking massage mechanism 1 and a pair of rack rails 2. The two sides of the walking massage mechanism 1 are clamped on the rack rails 2, and the rack rails 2 form the support for the walking massage mechanism 1. The walking massage mechanism 1 meshes with the rack surface of the rack rails 2 by means of the built - in gears, realizing the automatic reciprocating movement of the walking massage mechanism 1; the walking massage mechanism 1 can either carry its own battery or pick up power through the electrode rail parallel to the rack rails 2 to provide power for walking and massaging, and these are all common technologies.

[0030] A pair of rack rails 2 are arranged on a middle plate 3, and a support frame 4 is arranged outside the middle plate 3. At least one end of the middle plate 3 is connected to the support frame 4 through an elastic structure 5; or as Figure 4 , both ends of the middle plate 3 are connected to the support frame 4 through the elastic structure 5, and both ends have the ability of elastic deformation, with greater degrees of freedom. In addition, setting the support frame 4 can support the outer cloth cover and shape it.

[0031] Furthermore, the elastic structure 5 is preferably the following two types:

[0032] One Figure 1 , Figure 2 and Figure 4 , the middle plate 3 and the support frame 4 are integrally formed, and corrugations 51 are formed at the connection part; more specifically, both ends of the middle plate 3 are each connected through two corrugations 51. The width of the corrugations 51 is between 1 cm and 2 cm, and the spacing is greater than 5 cm, which can stably support the walking massage mechanism. This structure is the simplest and reduces the assembly workload.

[0033] Two Figure 5, the middle plate 3 and the support frame 4 are formed separately, and both ends of the middle plate 3 are suspended on the support frame 4 through tension springs 52. That is, both ends of the middle plate 3 are connected by two tension springs, and the tension springs are suspended at the four corners of the middle plate.

[0034] Since the rack rail 2 and the middle plate 3 are not exposed, and the walking massage movement 1 is mostly hidden, a layer of flexible cloth cover is generally wrapped around the device for both decoration and dust prevention, but the flexible cloth is often easily rolled into the rack rail 2. Therefore, the defect of cloth rolling can be solved by isolating the bottom of the walking massage movement 1.

[0035] Reference Figure 1 and Figure 3 , the support frame 4 is provided with anti-pinch strips 41 at the projections of the corners on both sides of the walking massage movement 1. The anti-pinch strips 41 can be set off at the bottom of the walking massage movement 1 to form an isolation effect on the wrapped fabric. In this example, the support frame 4 is shaped and wide, and the two ends of the anti-pinch strips 41 are connected to the support frame, and the rest of the positions are suspended. In addition, the side of the anti-pinch strip 41 is integrally formed with an upper folding retaining edge 42, such as Figure 3 The upper folding retaining edge 42 can block the side of the walking massage movement 1 and can also play an auxiliary stabilizing role, especially for the support frame 4 formed of a flexible material.

[0036] Reference Figure 4 and Figure 5 , which is a schematic diagram of a small massage cushion, the support frame 4 is relatively narrow, and the anti-pinch strip 41 is integrally formed with the frames on both sides of the support frame 4 to form a step structure with a high frame and a low anti-pinch strip.

[0037] Furthermore, the middle plate 3 and support frame 4, as well as the anti-pinch strip 41 mentioned above are all made of flexible materials, including similar elastic materials, such as plastic-molded support frames and middle plates, which can be deformed freely under force and have the characteristics of being able to fit the backrest of a chair or fit the curve of a human body. In order to reduce the resistance of the anti-pinch strip 41, the two ends of the anti-pinch strip 41 and the support frame 4 are also connected with a wave pattern, and can also float synchronously with the middle plate 3. In addition, the rack surfaces of the pair of rack rails 2 in the above example are back-to-back structures, and can also be relative structures, and a hollow groove 31 that is conducive to bending is opened on the middle plate 3.
