Description

Blood circulation stretch chair

This creation is related to equipment for relieving stress and stretching the body, especially a blood circulation stretching chair.

There are many types of chairs or reclining chairs on the market that can help users stretch their bodies, such as the products disclosed in domestic patents M659817, M576453 or M259523. In order to maintain the stability of their structure when stretched, these products must have a very stable base that can be placed on a flat surface. The base is stable and will not move to ensure the stability of the mechanisms on the base when operating. However, this also limits the use scenarios of this type of product and makes this type of product have only a single function.

The main purpose of this creation is to provide a blood circulation stretching chair that can vibrate to generate blood circulation and relieve stress and stretch.

In order to achieve the above main purpose, the Qi and blood circulation stretching chair of the invention comprises: a base, a plurality of leg frames are arranged below the base, and a support frame is arranged on the base. A first drive motor is arranged on the support frame, and the first drive motor has an output shaft, and an eccentric wheel is connected to the output shaft. A swing seat comprises: two side rods and a plurality of support rods arranged between the two side rods and connected to the two side rods. A cushion bracket is arranged on the two side rods of the swing seat and the eccentric wheel is connected to the cushion bracket. A back support frame and a foot support frame are respectively pivoted to the cushion bracket and can swing relative to the cushion bracket. The swing seat and the cushion bracket are each provided with a plurality of connecting seats, each of which corresponds to the position of the elastic columns. The swing seat and the cushion bracket are connected to the elastic columns via the connecting seats, so that the swing seat and the cushion bracket can be supported by the elastic columns and can move relative to the base and the support frame.

The applicant first explains that in this specification, including the embodiments described below and the claims of the patent application, the terms related to direction are based on the directions in the drawings. Secondly, in the embodiments and drawings to be introduced below, the same component numbers represent the same or similar components or their structural features. The directions indicated in the specification are based on the directions in the drawings for the sake of explanation and are not limited to this.

Please refer to Figures 1 to 7, which are the blood circulation stretching chair of this invention, including: A base 10, a plurality of leg frames 11 are provided below the base, a support frame 12 is provided on the base 10, and a plurality of elastic columns 13 are provided on the support frame 12 and the base 10. In this embodiment, there are six elastic columns, and the elastic columns 13 are made of elastic materials such as plastic or rubber, two of which are provided on the base and four of which are provided on the support frame.

A first drive motor 20 is disposed on the support frame 12. The first drive motor has an output shaft 21, and an eccentric wheel 22 is connected to the output shaft 21.

A swing seat 30 includes: two side rods 31 and two support rods 32 disposed between the two side rods 31 and connecting the two side rods.

A cushion bracket 40 is disposed on the two side rods 31. The cushion bracket 40 includes: four longitudinal pillars 41 and a cushion frame 42. The cushion frame 42 is a frame composed of a plurality of rods 43. The cushion frame 42 is connected to the eccentric wheel 22 of the output shaft at the bottom of a rod 43. The four longitudinal pillars 41 are respectively disposed on the two side rods 31 in groups of two-two-one. The cushion frame 42 is disposed on the four longitudinal pillars 41 and supported by the four longitudinal pillars 41.

A back support frame 50 is pivoted on the seat support 40 and can be swung relative to the seat support 40 to change the tilt angle of the back support frame 50.

A foot support frame 60 is pivoted on the seat support frame 40 and can be swung relative to the seat support frame 40 to change the tilt angle of the foot support frame 60.

A second drive motor 70 is provided on a rod 32 of the swing seat. The second drive motor 70 is connected to a first telescopic rod 71. The first telescopic rod 71 is pivoted to two swing arms, namely an upper swing arm 72 and a lower swing arm 73. One end of the lower swing arm 73 is pivoted to the first telescopic rod 71, and the other end is pivoted to the rod 32. One end of the upper swing arm 72 is pivoted to the first telescopic rod 71, and the other end is pivoted to the back plate support frame 50. The second drive motor 70 can drive the first telescopic rod 71 to extend and retract, and the movement of the first telescopic rod 71 can drive the upper swing arm 72 and the lower swing arm 73 to swing the back support frame 50 relative to the cushion frame 42, so that the back support frame 50 can change its tilting state from an upright sitting state to a reclining state.

A third drive motor 80 is provided on a rod 32 of the swing seat. The third drive motor 80 links a second telescopic rod 81. The second telescopic rod 81 is pivoted to a front swing arm 82 and a rear swing arm 83. One end of the rear swing arm 83 is pivoted to the second telescopic rod 81, and the other end is pivoted to the seat support 40. One end of the front swing arm 82 is pivoted to the second telescopic rod 81, and the other end is pivoted to the foot support frame 60. The third drive motor 80 can drive the second telescopic rod 81 to extend and retract, and the movement of the second telescopic rod 81 can drive the front swing arm 82 and the rear swing arm 83 to move, so that the foot support frame 60 can swing relative to the seat cushion frame 42, so that the foot support frame 60 can be raised or lowered to change its tilt angle.

The swing seat 30 and the cushion bracket 40 are each provided with a plurality of connecting seats 90, each of which corresponds to the position of the elastic columns 13. The swing seat 30 and the cushion bracket 40 are connected to the elastic columns 13 by the connecting seats 90, so that the swing seat 30 and the cushion bracket 40 can be supported by the elastic columns 13. In this embodiment, a connecting seat is provided on each of the four longitudinal pillars of the cushion bracket.

By means of the structure of the invention, the first drive motor 20 can drive the eccentric wheel 22 to link the seat support 40 and the swing seat 30 to produce eccentric vibration during use. Since the seat support 40 and the swing seat 30 are supported by the elastic columns 13, the seat support 40 and the swing seat 30 can have a stable support force under the support of the elastic columns 13 and can have a moderate swing and vibration range, so that the seat support 40 can produce a blood circulation effect with eccentric vibration.
