Description

The collapsible manually auxiliary mattress that rises and retires

Technical field

This utility model relates to a kind of collapsible manually auxiliary mattress that rises and retires, and the people can more easily be risen and retired.

Background technology

The existing device that rises and retires need have bigger strength could accomplish the process that rises and retires than complicated operations, user; The external force that then all needs that can more easily rise and retire is assisted; And existing rise and retire that device volume is big, complex structure, inconvenience carrying, can't be applicable to interim occasion and common domestic environment.

Summary of the invention

The purpose of this utility model is to provide a kind of collapsible manually auxiliary mattress that rises and retires, and this mattress makes old man, patient can more easily accomplish the process of rising and retiring, and processing ease, simple in structure, be easy to carrying.

The technical scheme of this utility model is so for this reason: the collapsible manually auxiliary mattress that rises and retires, comprise mattress, adjustable shelf, and mattress divides three; Connect in twos; The connecting axle at head and middle part is first, and apical head is equipped with back shaft, and the axial plane of back shaft has screw thread; On the axle two threaded axle sleeves of inwall are housed, the rotation direction of two sleeve lining screw threads is opposite mutually; Adjustable shelf is " Contraband " shape, and " Contraband " frame internal fixation has cloth, and there is the frame cover head center; Frame cover uses connecting rods to be connected with two axle sleeves respectively, and the adjustable shelf both sides are installed on first, makes the adjustable shelf can be around first rotation; First is passed through chain connection back shaft, and an end has removable crank.Use spring to connect between two axle sleeves.

Further improve as this utility model, described mattress head both sides side has the guide rail of band supported hole, and respectively there is a support bar on both sides; The support bar afterbody has a roller movable in the mattress guide rail, and there is the unidirectional button that can take in the roller in the roller outside, and spring is arranged at unidirectional button bottom; Spring can be with the unidirectional supported hole that heads into guide rail of buckleing; The support bar head is connected on the adjustable shelf, draws button outward, draws button through support bar inside and unidirectional buckle.

User will rise can load onto crank when sitting and shake and make first through the rotation of chain drive back shaft; Two axle sleeves that are in two ends on the back shaft cooperate under the effect of the screw thread screw thread that portion's rotation direction is opposite within it on the back shaft axial planes to be drawn close to the centre; The spring that this moment, shaft room was originally drawn back can provide very big power-assisted to guarantee that user need not use and get final product complete operation energetically; The unidirectional button that plays support bar in the seat process can buckle into the supported hole in the mattress guide rail one by one, user can be kept at an angle when needed recline on mattress.The button that draws when user is lain down on the bar of pull-up supported on both sides is respectively gone in the roller of support bar unidirectional deduct; Utilizing then from heavy sensation of the whole body keeps down adjustable shelf; Because the spring on the axle sleeve is drawn back gradually, the speed that user is lain down is guaranteed the comfortable and safe of user by fast and slow.In addition, can be with mattress three partially folded, further reduce occupation space, conveniently carry and deposit.

Compared with prior art, this utility model provides, and the collapsible manually auxiliary mattress volume that rises and retires is less, simple to operate, uses laborsavingly, can when occasion and common household temporarily, use, and in addition, user does not need other people help to get final product self-service rising and retiring yet.

The specific embodiment

Referring to Fig. 1, critical piece has mattress head 1, mattress middle part 2, mattress afterbody 3, adjustable shelf 6, frame cover 9, back shaft 10, axle sleeve 13, support bar 16,22, the first 23 on crank, chain 24, connecting rod 25.

Referring to Fig. 2 and Fig. 3, mattress head 1, mattress middle part 2 is connected with mattress afterbody 3 successively, and mattress head 1 both sides have guide rail 4 and supported hole 5.Referring to Fig. 4, adjustable shelf 6 heads center is equipped with frame cover 9, and respectively there are a support bar connecting hole 7 and axle connecting hole 8 in both sides, and adjustable shelf 6 inboards are fixed with cloth.Referring to Fig. 5, back shaft 10 axial planes are threaded, and head has gear 11 and Holder for hand crank 12, and in addition, first axle construction is identical with back shaft.Referring to Fig. 6, Fig. 7, axle sleeve 13 has connecting rod connecting hole 14 and spring connecting hole 15, and axle sleeve 13 inwalls have screw thread, and the thread rotary orientation of two axle sleeves is opposite.Referring to Fig. 8; Support bar 16 heads have adjustable shelf connecting thread 17 and draw button 18; Afterbody has unidirectional button 19, unidirectional button spring 20 and roller 21, draws button 18 can make in the unidirectional button 19 income rollers 21, decontrols and draws 18 o'clock unidirectional button springs 20 of button to buckle 19 and eject outside the roller 21 unidirectional.

Referring to Fig. 9, when rise sitting, shake crank 22 and make first 23 and begin to rotate; Pass through chain 24 for first 23 and drive 10, two axle sleeves of back shaft 13, under the rotation of back shaft 10 because the thread rotary orientation of inwall is opposite; Screw thread drive by back shaft 10 axial planes is drawn close in opposite directions; Prop up adjustable shelf 6 through connecting rod 25, axle sleeve spring 26 shrinks by drawing back state in playing the seat process gradually, has made the seat process more laborsaving.If need lie down, then spur drawing on the support bar 16 and detain 18 at this moment, lean on human body weight can drive adjustable shelf 6 and keep down gradually, because axle sleeve spring 26 is drawn back gradually at this moment, the speed of lying down can be by fast extremely comfortable and safe to guarantee slowly.Referring to Figure 10, can this utility model be folded up when carrying or depositing, mattress head 1 has closed up with mattress afterbody 3 when folding, the rotating shaft when mattress middle part 2 closes up as mattress head 1 and mattress afterbody 3, this moment, crank 22 took off.
