Detailed description of the invention
Embodiment, as shown in Figure 1: multistage adjustable board for lying on back of resting the head on, including the side arm 11 linked together and after-frame 12.
Generally, in use, this side arm 11 and this after-frame 12 link together in " 7 " font, and this side arm 11 and this after-frame 12 times
End be equipped be parallel to ground patch manage.The leading section of this side arm 11 upper end or this after-frame 12 is provided with support bar 21, before this
The bottom of frame 11 is provided with foot raker 22, and this after-frame 12 is provided with service creeper 30.That is, person taking exercise faces upward and lies on this service creeper 30, greatly
Leg is hooked on this foot raker 22 by support, the ankle portion of this support bar 21, the most upwards stands up, can carry out abdominal crunch
Take exercise.Meanwhile, the rearward end of this after-frame 12 is positioned at the rear of this service creeper 30 and is provided with headrest 40.Certainly, in order to realize folding,
This after-frame 12 can include after-frame leading portion and the after-frame back segment being hinged together, and this service creeper 30 includes being fixed on this after-frame leading portion
Front plate body and the rear plate body 32 that is fixed on this after-frame back segment.
Further, in conjunction with Fig. 2 to Fig. 4 and as shown in Fig. 7 to Fig. 9, this headrest 40 is connected in a lower slider 42.Should
Lower slider 42 front end is hinged on this after-frame 12 by a rotary shaft 41 in level.This rotary shaft 41 is through on this after-frame 12,
Both ends are exposed outside side, two, the left and right of this after-frame 12.Meanwhile, the cross section of this lower slider 42 is "U" shaped thus should
Lower slider 42 includes 2 in vertical side plate 421 and the transverse slat 422 of the upper side edge connecting these 2 side plates 421.Obviously, should
The both ends of rotary shaft 41 are through on these 2 side plates 421 respectively.And, 2 side plates 421 of this lower slider 42 are provided with at least 2
Group altitude location hole 4211.I.e., often group altitude location hole 4211 includes the hole, 1 location being respectively arranged on 2 side plates 421,
And hole, can align 2 location forms 1 group of altitude location hole 4211.It is furnished with latch 43 in altitude location hole 4211, is inserted in height
Latch 43 and the upper side edge of this after-frame 12 in hole 4211, degree location match.That is, the latch 43 being inserted in altitude location hole 4211
Can be supported by this after-frame upper side edge.So, this latch 43 is inserted in different altitude location holes 4211, can be made this
The rear end of lower slider 42 has different height, so that the height of this headrest 40 is regulated.
Further say, in conjunction with Fig. 2, Fig. 5, Fig. 6 and as shown in Fig. 7 to Fig. 9,2 side plates of this lower slider 42
Being positioned at the chute 4212 being arranged over front and back moving towards in those altitude location holes 4211 on 421, this chute 4212 is generally horizontal
Shape or horizontal.Obviously, meanwhile, this headrest 40 is fixed in a carriage 44.The cross section of this carriage 44 be "U" shaped from
And this carriage 44 includes 2 in vertical wing plate 441 and the connecting plate 442 of the upper side edge connecting these 2 wing plates 441.With
And, these 2 wing plates 441 are installed with a sliding pin 4411, this sliding pin 4411 can being through in this chute 4212 of slide anteroposterior.Also
That is, this carriage 44 can along with this sliding pin 4411 slide anteroposterior.The downside edge of these 2 wing plates 441 is provided with 1 group of cunning
Dynamic spacing hole 4412.That is, these 2 wing plates 441 being respectively equipped with a spacing hole, these 2 spacing holes align thus form this group and slide
Dynamic spacing hole 4412.Slip spacing hole 4412 and altitude location hole 4211 match.That is, this group slip spacing hole 4412 and any one
Group altitude location hole 4211 all can align.Latch 43 can be inserted in slip spacing hole 4412.So, this carriage 44 is entered
Row slide anteroposterior, after sliding into correct position, inserts this latch 43 this group slip spacing hole 4412 aligned and slides with this group
In the altitude location hole 4211 that dynamic spacing hole 4412 aligns, i.e. adjustable and stabilize this headrest 40 position in the longitudinal direction
Put.Obviously, the height of this headrest 40 is the most also defined.
Certainly, after defining this headrest 40 position in the longitudinal direction, also can take a latch 43 again and be inserted in another
In group altitude location hole 4211, the height of this headrest 40 can be made to be further enhanced.Otherwise or, at the elevation angle of headrest 40
The most adjusted to maximum rating, still this headrest 40 can be made to have by adjusting headrest 40 positions in the longitudinal direction
Higher height.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, every utilization
Equivalent structure or equivalence flow process that description of the invention and accompanying drawing content are made convert, or it is relevant to be directly or indirectly used in other
Technical field, be the most in like manner included in the scope of patent protection of the present invention.
