Description

Technical Field

[0001] The present invention relates to a massage appliance, particularly a massage chair capable of internally hiding a leg and foot massage part. Background Art

[0002] In the prior art, a massage chair can not only massage the back and buttocks of a human body, but also massage the lower limbs of the human body. The leg and foot massage part for massaging the lower limbs of the human body is generally installed at the front part of the massage chair, and its elevation angle can be adjusted to meet the use requirements. However, the setting of the leg and foot massage part greatly increases the volume of the massage chair, makes the front-back dimension of the massage chair larger, occupies a large space, is inconvenient for packing and transportation, and often needs to be disassembled, and the operation is very cumbersome. When only the back and buttocks need to be massaged without massaging the legs and feet, the setting of the leg and foot massage part will cause inconvenience to users when getting on and off the massage chair, which is not conducive to use.

[0003] In order to solve the above problems, the existing Chinese invention patent with the patent number 200510094315.8 discloses a massage chair capable of internally hiding a leg kneading device. The massage chair can use a push-pull mechanism to hide the leg kneading device inside the massage chair, which not only reduces the volume of the massage chair, but also provides more convenience and comfort for users. However, the structure of the push-pull mechanism in the above patent is relatively complex, with many driving devices, which not only increases the overall volume, has a high manufacturing cost, consumes more electric power resources during use, has a high use cost, but also is more troublesome to repair once a problem occurs.

[0004] Another example is the Chinese invention patent with the patent number 200810020048.3, which discloses a massage chair capable of internally hiding a leg kneading device, including a leg kneading device placed at the front part of the massage chair. A push-pull mechanism capable of driving the leg kneading device to move in and out of the massage chair chassis is arranged inside the massage chair. The push-pull mechanism includes an arc-shaped push rod. One end of the arc-shaped push rod is pin-connected to the lower rear part of the leg kneading device, and the other end of the arc-shaped push rod is pin-connected to the upper part of the massage chair chassis. A pushing device is arranged inside the massage chair chassis, and the pushing device can push the arc-shaped push rod to rotate back and forth with the pin connection point on the upper part of the massage chair chassis as a fulcrum, so as to drive the leg kneading device to move outwards or be internally hidden. However, the leg kneading device in the above device is only pin-connected to the arc-shaped push rod at its lower rear part and is not well fixed, which will inevitably affect its use effect, and its mechanical reliability needs to be improved. Its service life will be greatly shortened after long-term work. Summary of the Invention

[0005] The purpose of the present invention is to provide a massage chair capable of internally hiding a leg and foot massage part. The present invention has the characteristics of simple structure, good mechanical reliability, and capable of deeply internally hiding the leg and foot massage part.

One end of the telescopic device is hinged to the hanging ear, and the other end of the telescopic device is hinged to the hinge seat.

[0010] In the aforesaid massage chair capable of hiding a leg and foot massage part, the telescopic device is an electric push rod.

[0011] In the aforesaid massage chair capable of hiding a leg and foot massage part, the connecting surface AB is formed by the center line of the front end A and the center line of the rear end B of the sliding groove, and the connecting surface AC is formed by the center line of the front end A of the sliding groove and the center line of the hinge hole C of the hinge seat. An included angle α is formed between the connecting surface AB and the connecting surface AC. When the leg and foot massage part is in the extended working state, α≥90°; When the leg and foot massage part is in the intermediate state, 80°≤α≤100°.

[0012] In the aforesaid massage chair capable of hiding a leg and foot massage part, the extended working state means that the slider is at the front end A of the sliding groove, and the included angle between the connecting surface AC and the horizontal plane is less than 90°; The intermediate state means that the slider is at the front end A of the sliding groove, and the leg and foot massage part abuts against the limiting member.

[0013] In the aforesaid massage chair capable of hiding a leg and foot massage part, the outer end of the slider extends out of the sliding groove and is fixed with a limiting piece.

[0014] In the aforesaid massage chair capable of hiding a leg and foot massage part, the cross section of the limiting piece is circular, and the diameter of the limiting piece is greater than the width of the sliding groove.

[0015] In the aforesaid massage chair with a retractable leg massage part, the slider is shaft-shaped, and a pulley located in the chute is sleeved on the slider, and the pulley is rotatably connected to the slider.

[0016] Compared with the prior art, through the special connection mode between the leg massage part and the massage chair seat part of the present invention, through the cooperation and movement of the slider and the chute, and the combined use of the telescopic device and the limiting part, the leg massage part and the massage chair seat are designed to be rotatable and slidable, so as to realize the extension and retraction of the leg massage part, and well solve the problem that the leg massage part occupies space when not in use;

[0017] The slider can not only serve as the rotation center of the leg massage part in the chute to realize the rotation of the leg massage part, adjust the pitching angle, provide more massage postures, and improve the massage comfort; but also can move back and forth along the chute. By changing the front and rear positions of the leg massage part, the leg massage part can be further and more deeply retracted under the massage chair seat, reducing the occupied space, being convenient for use, transportation and placement, reducing the transportation cost, providing more user-friendly services for customers, and increasing the market competitiveness; at the same time, the designed structure is simple, the overall number of components used is small, only one driving part is used, the manufacturing and maintenance are relatively easy, the cost is low, the power energy consumed during use is also small, and it is convenient to be widely promoted; through the specific design of the slider, the working stability performance of the leg massage part is good when extending and retracting, and it is not easy to occur the phenomena of jamming and deviation, improving the mechanical reliability and service life;

[0024] The following further illustrates the present invention in conjunction with embodiments, but it shall not be used as the basis for limiting the present invention.

[0025] Embodiment

[0026] As Figures 1-4 shown, a massage chair with a retractable leg and foot massage part includes a massage chair seat part 1. A leg and foot massage part 2 is provided on the front side of the massage chair seat part 1. A pair of parallel lugs 11 are provided on both sides of the massage chair seat part 1. A chute 11a is formed on the lug 11. On both upper ends of the leg and foot massage part 2, a pair of columnar sliders 21 corresponding to be inserted into the chute 11a are provided in parallel. The slider 21 cooperates with the chute 11a to slide and / or rotate, that is, the slider 21 can slide in the chute 11a and can also rotate around its own axis; A telescopic device 3 for driving the leg and foot massage part 2 to rotate and lift is provided under the massage chair seat part 1. The telescopic device 3 pushes the leg and foot massage part 2 to translate relative to the massage chair seat part 1 and can also rotate with the slider 21 as the central axis.

[0027] According to the structure of the actual massage chair, the lengths of the lugs 11 and the chute 11a can be adjusted, so as to adjust the retractable degree of the leg and foot massage part 2. The lugs 11 can be provided at the front end of the massage chair seat part 1 to retract the leg and foot massage part 2 at the front end of the massage chair seat part 1. A cushion is placed above the massage chair seat part 1 to cover the massage chair seat part 1 and the leg and foot massage part 2; The lugs 11 can also be provided under the massage chair seat part 1 to retract the leg and foot massage part 2 under the massage chair seat part 1.

[0028] The chute 11a is a long oval hole structure or a shape approximately like a long oval hole. The front end A of the chute 11a can form a recess downward to facilitate the limiting rotation movement of the slider. The front end A of the chute 11a is lower than the rear end B of the chute 11a.

[0029] The included angle between the connection surface AB formed by the center line of the front end A and the center line of the rear end B of the chute 11a and the horizontal plane is between 5 degrees and 20 degrees.

[0030] A hanging ear 12 is provided on the massage chair seat part 1, and a hinge seat 22 is provided on the leg and foot massage part 2. One end of the telescopic device 3 is hinged to the hanging ear 12, and the other end of the telescopic device 3 is hinged to the hinge seat 22. The telescopic device 3 is an electric push rod. The electric push rods can be symmetrically distributed on both sides of the leg and foot massage part 2 to improve the working stability. In addition to the electric push rod, other devices that play a pushing role can also be used.

[0031] The center line of the front end A of the chute 11a and the center line of the rear end B of the chute 11a form a connection surface AB, and the center line of the front end A of the chute 11a and the center line of the hinge hole C of the hinge seat 22 form a connection surface AC. An angle α is formed between the connection surface AB and the connection surface AC. When the leg and foot massage part 2 is in the extended working state, that is, the slider 21 is at the front end A of the chute 11a, and the angle between the connection surface AC and the horizontal plane is less than 90°, α≥90°, to prevent the calf or heel from pressing the leg and foot massage part when the user uses the leg and foot massage, causing the leg and foot massage part to swing. When the leg and foot massage part 2 is in the middle state, that is, the slider 21 is at the front end A of the chute 11a, and the leg and foot massage part 2 is in contact with the limiter 13, 80°≤α≤100°, which is conducive to the smooth sliding of the slider 21 during the storage process of the leg and foot massage part.

[0032] The outer end of the sliding block 21 extends out of the sliding groove 11 a and is fixed with a limiting piece 24 .

[0033] The cross section of the limiting piece 24 is circular, and the diameter of the limiting piece 24 is larger than the width of the slide groove 11a. The limiting piece 24 abuts against the outer side of the hanging ear 12 to limit the left and right movement of the leg and foot massage part 2 without hindering the forward and backward sliding of the leg and foot massage part 2, thereby ensuring the stability and smoothness of the leg and foot massage part 2 when moving.

[0034] The slider 21 is in the shape of an axis, and a pulley 23 located in the slide groove 11a is sleeved on the slider 21, and the pulley 23 is rotatably connected to the slider 21. The diameter of the pulley 23 is slightly smaller than the groove width of the slide groove 11a, so that the pulley 23 can move or roll in the slide groove 11a together with the slider 21, thereby reducing friction and wear, and improving mechanical reliability and service life.

[0035] The pulley 23 and the limiting plate 24 may be an integrated structure or a separate structure.

[0036] The front end of the bottom of the massage chair seat 1 is provided with a limiter 13 for limiting the movement of the leg and foot massage part 2, and the limiter 13 can be arranged below the telescopic device 3. The limiter 13 can be a roller structure, which is fixedly mounted on the massage chair seat 1 at a position corresponding to the leg and foot massage part 2, and resists the leg and foot massage part to prevent it from continuing to swing, but cannot hinder its sliding, and reduces the friction resistance between the limiter 13 and the leg and foot massage part 2 as much as possible, so that the leg and foot massage part 2 can be smoothly contracted.

[0037] Working principle:

[0038] Figure 2 Figure 3 Figure 4 They respectively represent three typical states of the leg and foot massage part 2 of the massage chair when the lugs 11 are arranged on both sides of the front end of the massage chair seat part 1, namely, extended to work, extended to the middle, and completely retracted.

[0039] Process of retraction of the leg and foot massage part: When the leg and foot massage part 2 is in the extended working state, the slider 21 is located at the front end A of the sliding groove 11a, and at this time, the electric push rod is in the extended state. Drive the electric push rod to shorten it, then the leg and foot massage part 2 rotates counterclockwise with the slider 21 (which is also the center of the front end A of the sliding groove 11a) as the center; when the leg and foot massage part 2 rotates until it touches the limiting member 13, it stops rotating, and under the further pulling force of the electric push rod, the slider 21 leaves the front end A of the sliding groove 11a and moves towards the rear end B of the sliding groove 11a; when the slider 21 reaches the rear end B of the sliding groove 11a, it stops moving, and at this time, the leg and foot massage part 2 is completely retracted under the massage chair seat part 1.

[0040] Process of extension of the leg and foot massage part: When the leg and foot massage part 2 is in the completely retracted state, the slider 21 is located at the rear end B of the sliding groove 11a, and at this time, the electric push rod is in the shortened state. Drive the electric push rod to extend it, then under the action of gravity, the slider 21 on the leg and foot massage part 2 starts to slide down from the rear end B of the sliding groove 11a; when the slider 21 slides down to the front end A of the sliding groove 11a, it stops sliding; thereafter, under the further pushing force of the electric push rod, the leg and foot massage part 2 rotates clockwise with the slider 21 (which is also the center of the front end A of the sliding groove 11a) as the center until it rotates to the required angle and can be used normally like a conventional massage chair.
