Description

A kind of inclined-plane mahjong

Technical field

The invention belongs to apparatus for entertainment, be specifically related to the healthy mahjong of a kind of people of being conducive to.

Background technology

Mahjong is a kind of board class apparatus for entertainment of developmental game. Current mahjong is all cuboid, and decorative pattern or printed words are carved with in front, and the back side is setting as required. Along with the raising of people's living standard, people are more and more higher to the demand of spirit, and amusement is exactly one of them. Mahjong is one of main apparatus for entertainment, and mahjong fan is innumerable especially, and plays for a long time mahjong and be conducive to mental exercise, delays senile dementia. But in playing mahjong, it between mahjong and desktop, is plumbness, form the state of bowing for a long time, will will cause cervical vertebra to be not suitable with or even become cervical spondylopathy the people of frequent object for appreciation mahjong like this, secondly when seeing due to people, between eyes and mahjong, be a parallax, therefore, in the time of insufficient light or in the time that light is inhomogeneous, will cause fatigue or even eye illness to eyes.

Summary of the invention

The object of the invention is to exist and under the bad condition of light, be unfavorable for identification in order to overcome existing mahjong, cause eye fatigue, the deficiencies such as cervical vertebra fatigue, a kind of mahjong of brand new is proposed, to alleviate eyes and cervical vertebra fatigue in the situation that of long-time object for appreciation mahjong, reduce the generation of cervical spondylopathy and disease of eye.

The technical scheme that the present invention adopted is to achieve these goals:

A kind of inclined-plane mahjong, it comprises the matrix that is carved with pattern or word, it is characterized in that: in four faces on described matrix except front and back, at least one face is inclined-plane, and the front that makes matrix, this inclined-plane higher than or be wider than the back side (being the area that positive area is greater than the back side).

Inclined-plane described in the present invention can also be divided into following several situation: the bottom surface of matrix or end face are inclined-plane; At least two relative sides of matrix are inclined-plane; The bottom surface of matrix and end face are all inclined-plane; And the gradient (angle between inclined-plane and horizontal plane) on two relative inclined-planes of described matrix is identical. The gradient of two opposite faces is arranged to the identical outward appearance of mahjong that makes more attractive in appearance.

The technical scheme being more preferably in the present invention is that the angular range between described inclined-plane and horizontal plane is less than 30 ° for being greater than 0 °, is further that the angular range between described inclined-plane and horizontal plane is less than 20 ° for being greater than 0 °. The angle of the angle the best in the present invention between inclined-plane and horizontal plane is 11 °-15 °, so both can guarantee daylighting successful, therefore can alleviate the fatigue strength of cervical vertebra and eyes; Can prevent that opponent from peeping the mahjong of oneself, is conducive to fair play simultaneously.

The face material density of matrix described in the present invention is greater than backing material density, angle between inclined-plane and horizontal plane is larger, positive density of material is more greater than backing material density, so just the center of gravity of mahjong can be shifted to front, avoids mahjong to be shifted onto easily.

Cervical spondylopathy (cervicalspondylosis) be because of degeneration of cervical intervertebral disc, cervical vertebrae hyperosteogeny caused, with neck and shoulder ache, emit to headrest portion or upper limbs, there are two lower limb spasm in severe one very, difficulty in walking, so that the syndrome that quadriplegia is main manifestations. Cause cervical spondylopathy and mainly contain following key factor: 1. lean over a book for a long time, read newspaper, see playing cards, mahjong etc., because long-term holding head neck is in single postural position, cause local excessive activity thereby easily suffer from cervical spondylopathy, damage local interverbebral disc, ligament etc., cervical spondylopathy easily occurs. 2. Head and Neck wound personnel: Head and Neck wound does not directly cause cervical spondylopathy, but cervical spondylopathy produces the Acute aggravated factors of symptom often, some patients are because of cervical vertebrae hyperosteogeny, cervical intervertebral disk bulging, the interior soft tissue lesions of canalis spinalis etc. causes cervical spinal canal in narrow critical condition, the generation of the normal induced symptom of additional neck wound, even paralysis occurs. 3. faulty posture: see TV as lied on a bed, reading, high pillow, seat sleep etc.; On sleeping carriage, sleep, when sleeping muscle protection effect poor, when brake, be prone to neck injury. 4. the depauperation of instability: congenital little canalis spinalis is also pathogenesis basis. The incidence of disease of cervical vertebra central authorities canalis spinalis, the narrow and small person's cervical spondylopathy of nerve root canal is higher 1 times than normal person. Pay close attention to a certain things if bowed for a long time as can be seen here, easily make cervical vertebra fatigue, cause cervical spondylopathy. Bow for a long time as can be seen here and pay close attention to an event, be easy to cause cervical vertebra fatigue and initiation cervical spondylopathy.

The present invention changes the upper and lower surfaces of existing mahjong into inclined-plane, therefore in playing mahjong, when mahjong is stood on desktop, what mahjong just tilted stands on desktop, and the front of mahjong is the intermediate, inclined to desk, so just improve daylighting effect, thereby people's eyes have been played a very good protection; Meanwhile, also make the reclinate angle of cervical vertebra reduce, thereby reduced the degree of fatigue of cervical vertebra, cervical vertebra is played a very good protection, thereby reduced the probability that causes cervical spondylosis.

Due to the present invention by the side of mahjong be arranged to tilt, can change the sight angle of eyes, thereby can correct people's sitting posture, particularly a few high people, have good protective effect to its vertebra especially.

The present invention reduces materials by side beveling time, therefore reduced production cost.

The present invention has simple in structure, use, cheap for manufacturing cost in sum, can effectively alleviate the degree of fatigue of cervical vertebra, vertebra and eyes, and the generation of prevention cervical spondylosis, eye illness and spinal disease, is conducive to the advantages such as healthy.
