Abstract

The utility model provides a body-building chair which comprises a chair seat, a chair rack and a chair back of which the gradient can be adjusted. The utility model is characterized in that both sides of the chair rack are symmetrically hinged with force arms capable of pushing in a lateral mode towards the exterior through a crossed movable sleeve, and the top end of each force arm is provided with a holding rod; the bottom of each force arm is correspondingly hinged with piston rods of two steam springs positioned below the chair seat, and the other end of each steam spring is hinged with one side of the chair rack, which is hinged with the other force arm. The two force arms are arranged at both sides of the chair rack in a hinged mode, and the two force arms and the two steam springs positioned below the chair seat form a chest-expanding pulley weights; when arms push the force arms towards the external lower side, the steam springs contract to a dead spot; the arms relax, and the force arms can automatically reset; after the force arms reset, the purpose of arm strength can be achieved through repeating the action. The utility model achieves the arrangement of a body-building structure without breaking the integrity of the chair. The utility model has the characteristics of simple structure, convenient body building, low cost, etc.

Description

Ab lounge

Affiliated technical field

The utility model provides a kind of ab lounge, specifically is a kind of chair that can temper arm strength.

Background technology

At sit clerk's activity less, the present situation of physique difference, existing many at present technology reports about body-building chair, as electric massage chair or the like, very important person is sitting in top opening power and just can performs physical exercise, defective costs an arm and a leg, the people is sitting in the top passive exercise of accepting, and its body-building effect is also not satisfactory.In view of the above problems, the technology report of at present existing mechanical ab lounge, as Chinese patent communique disclosed utility model patent on June 15th, 1994: ab lounge, the patent No.: 93221954, the tool technology contents is: be provided with the inverse-U-shape rack that can stretch up and down in the chair back, be provided with pulley on the entablature of this support, be provided with the vertical chest expander of upper limbs on backrest, the pulling force rope in the chest expander walks around pulley and the pulling force handle joins.The back frame and the chair back side rack of armrest support are hinged, and are provided with left and right lateral pull spring on seat bracket, and they connect with the armrest support bottom makes handrail constitute a chest expanding chest expander.Though this ab lounge can reach the purpose of tempering arm strength, keeping fit, complex structure, its serviceability also needs further improvement.

The utility model content

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, simple in structure, ab lounge that serviceability is good.Its technical scheme is:

Comprise seat support, chair frame and the adjustable chair back of gradient, it is characterized in that: the arm of force that is hinged with outside thruster in the and arranged on left and right sides of chair frame through intersection movable sleeve symmetry, the top of the arm of force is provided with holding rod, its bottom is corresponding hinged with the piston rod that is positioned at seat support below two vapour springs, and it is hinged that the other end of vapour spring and chair frame are hinged with a side of another arm of force.

Described ab lounge, each intersection movable sleeve comprises 90 ° of fixedly connected lassos of 2 intersections, wherein the lasso of horizontal axis flexibly connects through bearing pin and the key seat that is fixed on the chair frame, and the arm of force passes the lasso of vertical axial, and the piston rod of its bottom and vapour spring is hinged.

Described ab lounge, the arm of force are sleeved on together at intersection movable sleeve place by upper and lower two parts and form, and the movable sleeve that intersects is provided with the adjusting set bolt.

Its operation principle is: two arm of forces are hingedly mounted on the and arranged on left and right sides of chair frame, the vapour spring of they and seat support below just constitutes the chest expanding chest expander, the people is sitting in the chair, when the outside below of arm promotes the arm of force, the vapour spring is contracted to the dead point, arm loosens and can automatically reset, and so can reach the purpose of tempering arm strength repeatedly easily.It compared with prior art, the personnel of body-building are in a kind of active state all the time, and need not consume other power again, under the condition of not destroying the chair integrality, realize the setting of body-building structure, have advantages such as simple in structure, that cost is low, body-building is convenient, body-building effect is good.

The specific embodiment

1, seat support 2, chair frame 3, the chair back 4, the arm of force 5, intersection movable sleeve 6, piston rod 7, vapour spring 8, adjusting set bolt 9, holding rod 10, lasso 11, bearing pin 12, key seat

Two arm of forces, 4 correspondences are hingedly mounted on the and arranged on left and right sides of chair frame 2 through intersection movable sleeve 5 symmetries, each intersection movable sleeve 5 comprises 90 ° of fixedly connected lassos 10 of 2 intersections, wherein the lasso 10 of horizontal axis flexibly connects through bearing pin 11 and the key seat 12 that is fixed on the chair frame 2, the arm of force 4 passes the lasso 10 of vertical axial, its bottom is hinged with the piston rod 6 that is positioned at seat support 1 below vapour spring 7, it is hinged that the other end of vapour spring 7 and chair frame 2 are hinged with a side of another arm of force 4, and such two arm of forces 4 just constitute the chest expanding chest expander with the vapour spring 7 of seat support 1 below.The arm of force 4 is sleeved on together at intersection movable sleeve 5 places by upper and lower two parts and forms, and the movable sleeve 5 that intersects is provided with regulates set bolt 8, the length that can regulate the arm of force 4 like this, and then regulate the intensity of taking exercise.
