The utility model content
The purpose of this utility model be to provide a kind of can comprehensive exercise back and the back-rest means for chair of the Abdomen strengthening chair of abdominal muscles.
To achieve these goals, solution of the present utility model is:
The back-rest means for chair of Abdomen strengthening chair is made up of keel, turning joint and elastomer at least, and the keel of below are fixed on the seat support, and the more piece keel stack together, and are movably connected by turning joint and elastomer between the adjacent keel.
The bottom of above-mentioned turning joint is hubbed on the keel of below by pivot, necking segment is formed at the top of turning joint, the both sides of necking segment are respectively by there being a hack lever, two hack levers are hubbed on respectively on the keel of top, and the top of turning joint cooperates with its necking segment by two hack levers and on the frame keel up.
The upper and lower part of above-mentioned turning joint is hubbed on the keel of above and below by pivot respectively.
Above-mentioned each keel are overlooked and are the cashew nut shape.
Offer three perforation in left, center, right on above-mentioned each keel, elastomer is the rubber-like rope, and three elastomers are set in respectively in the perforation of each keel correspondence, and each elastomeric two ends is fixed on the top and on the keel of below.
The step surface of the top formation depression of above-mentioned keel, the bottom of turning joint is installed on the step surface.
The above-mentioned keel of below are installed on the holder, and holder is fixed on the seat support.
Above-mentioned each keel also are coated with foam outward.
A handgrip is installed in the keel both sides of above-mentioned the top.
Headrest also is installed in the above-mentioned handgrip.
After adopting said structure, when the utility model used, the people was sitting on the seat support, leans against on the keel of back-rest means for chair.The person taking exercise embraces the handgrip of top with hand, overcome elastomeric elastic force effect, do forward and bend over, upwards stretch or move to the left and right lateral bending waist of doing, can bend or upwards stretching forward or to left and right by all keel of turning joint interlock, reach the purpose of comprehensive exercise back and abdominal muscles by elastomeric elastic force.The backrest profile of this Abdomen strengthening chair meets ergonomics, cooperates the human body back shaped design.

The specific embodiment
Shown in Fig. 1,3, the back-rest means for chair of the Abdomen strengthening chair that the utility model discloses is made up of keel 1, turning joint 2 and elastomer 3 at least.
Wherein, more piece keel 1 stack together.The keel 1 of below are fixed on the seat support 4, install for convenience, can fix a holder 41 earlier on seat support 4, and the keel 1 of below are installed in this holder 41 again.For the height lifting according to need that makes keel 1, present embodiment also is fixedly mounted on holder 41 on the seat support 4 by telescoping tube 42.In order to adapt to human body back muscle form, present embodiment also is designed to each keel 1 to overlook and is the cashew nut shape, and cashew nut shape projection can be massaged human body back at the volley.In order to increase the comfortableness of use, present embodiment also is coated with foam 6 outside each keel 1, cooperates shown in Figure 2.
Be movably connected by turning joint 2 and elastomer 3 between the adjacent keel 1.Connected mode between turning joint 2 and the keel 1 has a lot, shown in present embodiment Figure 1A, 4, be to be hubbed on the bottom of turning joint 2 on the keel 1 of below by pivot 21, form necking segment 22 (both sides are vertically forming depression) on the top of turning joint 2, the both sides of necking segment 22 are respectively by there being a hack lever 23, two hack levers 23 are hubbed on respectively on the keel 1 of top, the top of turning joint 2 cooperates with its necking segment 22 by two hack levers 23 and on the frame keel 1 up, spacing by hack lever 23, turning joint 2 can be up and down or side-to-side movement; On the keel 1 above also the top of turning joint 2 also can being hubbed on by pivot as the bottom (this paper does not give diagram); Perhaps the bottom of turning joint 2 is fixed (or one-body molded) below keel 1 on, and the top of turning joint 2 cooperates with hack lever 23 by necking segment 22 shown in Figure 1A and on the frame keel 1 up, also or be hubbed on by pivot on the keel 1 of top ...For the ease of turning joint 2 is installed and make curve between each keel 1 more smooth and easy, the step surface 11 of the top formation depression of keel 1, the bottom of turning joint 2 is installed on the step surface 11.Elastomer 3 can be common spring or elastic threads etc., connected mode between elastomer 3 and the keel 1 also has a lot, as shown in this embodiment, be on each keel 1, to offer three perforation 12 in left, center, right, elastomer 3 is three long rubber-like ropes, three elastomers 3 are set in respectively in the perforation 12 of each keel 1 correspondence, and the two ends of each elastomer 3 are fixed on the top and on the keel 1 of below; Elastomer 3 also can be some short ropes or spring, and its two ends are separately fixed on two adjacent keel 1.
The concrete connected mode of the concrete structure of the number of keel 1, turning joint 2, turning joint 2 and elastomer 3, the radical of elastomer 3 etc. are not limited by this paper all.
For the ease of using, present embodiment is installed a handgrip 5 on the keel 1 of the top.For the height lifting according to need that makes handgrip 5, handgrip 5 also is installed on the keel 1 of the top by telescoping tube 51.In order to make the person taking exercise that head when taking exercise relies on to some extent, headrest 7 is installed also on handgrip 5.
When the utility model uses, cooperates shown in Figure 5ly, the people is sitting on the seat support, leans against on the keel 1 of back-rest means for chair, and headrest is being rested the head on 7.The person taking exercise with pull stop 5 or embrace above keel 1, cooperate among Fig. 6 shown in the arrow, overcome the elastic force effect of elastomer 3, do the action of bending over forward, move to the left and right lateral bending waist of doing, or upwards stretch (because necking segment 22 can provide the space that upwards stretches) do drawing-in motion, by all keel 1 of turning joint 2 interlocks forward, to left and right curved or extend upward, and reach the purpose of comprehensive exercise back and abdominal muscles by the elastic force of elastomer 3.
