Abstract
Description
[Technical field]
[0001] The present invention relates to a chair for office use etc., which can easily massage the soles of the feet in a simple manner. [Background technology]
[0002] Since ancient times, there have been various "pressure points" on the soles of the human feet, and it is said that pressing and stimulating these points can improve blood circulation, activate the brain and internal organs, and help treat various illnesses.
[0003] For this reason, various foot massage devices are available and used as health equipment.
[0004] When using these foot massage devices while sitting in a chair, there are devices that are placed on the floor and devices that are attached as separate parts to the legs of the chair, and further there are devices that require power and devices that do not.
[0005] As a powered device, it is primarily used by placing it on the floor, and uses an electric motor to vibrate the protrusions on the part where the feet are placed, stimulating the soles of the feet.
[0006] Non-powered devices include those that are placed on the floor and those that are attached as separate parts to the legs of a chair, but there are also those that stimulate the soles of the feet by placing the feet on protrusions on the device and moving the feet back and forth, or those that stimulate the soles of the feet by stepping on them with your body weight. [Prior art documents] [Patent documents]
[0007] Utility model document 1 Utility model registration No. 3166716 (U3166716) Utility model document 2 Utility model registration No. 3194677 (U3194677) Utility model document 3 Utility model registration No. 3187668 (U3187668) Utility model document 4 Utility model registration No. 3139291 (U3139291) Summary of the Invention [Problem to be solved by the invention]
[0008] However, if this foot massage device is placed on the floor and used while sitting on a chair, when the chair is moved forward or to the side after sitting on the seat, the foot massage device hits the legs or casters of the chair and gets in the way.
[0009] Furthermore, these floor-mounted devices, especially those that do not require power, require you to move your feet back and forth or step on them with your body weight, but if you use them while sitting on a chair with casters, the chair will move, making it difficult to use.
[0010] In addition, foot massage devices that require power generate vibrations and noise, which can be a nuisance to those around you when you are at work.
[0011] Furthermore, since this device is designed to generate vibrations from an electric motor, it has a large number of parts and is expensive.
[0012] In addition to this, foot massage devices that are attached to the legs of chairs as separate parts also have a large number of parts and are expensive.
[0013] Furthermore, this device stimulates the soles of the feet when you step on it with your body weight, so it needs to be firmly fixed to the legs of the chair, and since it is a relatively large part, it gets in the way when you move the chair or your feet while sitting.
[0014] To provide a chair with a sole massage function that is easy to use and does not get in the way of chair or foot movement, does not make noise, and even if you put your weight on the protruding part, the chair will not move, making it easy to stimulate the soles of the feet, and has almost no increase in cost. [Means for solving the problem]
[0015] This chair with a sole massage function is characterized in that a protrusion of a massage part (6a) which is an extension of the chair leg (6) and is either integral with the leg or a partly separate from the leg is provided at the upper part of the leg tip, and the sole of the foot can be massaged by stepping on the protrusion with the foot while sitting on the chair. Effect of the Invention
[0016] According to this invention, by simply providing a protrusion on the tip of the leg of an existing chair, a chair with a foot massage function can be created, with almost no increase in cost. Furthermore, the position of this protrusion does not get in the way of one's feet or other objects, and since it is close to the point on the floor that supports the weight of the chair and the person, the chair will not move or slip even if stepped on. Furthermore, since the position of this protrusion is close to the center of gravity of the person, it is possible to step on it with one's weight. Therefore, the pressure points on the soles of the feet can be easily stimulated in a stable position. Furthermore, since it does not generate noise, it does not bother those around you.

Claims
[Claim 1] This chair with a sole massage function is characterized in that it is located on the extension of the chair leg (6) and has a protrusion of a massage part (6a) which is integral with the leg or a part separately provided on the upper part of the tip of the leg.
