The content of the invention

The technical problem to be solved in the present invention, is to be directed to the defect of above-mentioned prior art, makes improvements, to provide What a kind of lying or leaning comfortable use good for health suitable family easy to operate used can adjust Wo Jiao bed and its head of a bed back board device.

The present invention solve above-mentioned technical problem technical scheme be：A kind of to adjust Wo Jiao bed, this can adjust Wo Jiao bed Head end is provided with head of a bed back board device, and head of a bed back board device includes apparatus body, guide, movement parts and backup plate, and guide is installed In apparatus body, movement parts are engaged with guide to be moved up and down along guide, and backup plate is rotated by its upper end and movement parts Connection, the head end that the lower end edge of backup plate can get off from apparatus body from the bed that can adjust Wo Jiao can adjust Wo Jiao to be placed on a distance from different Bed bed surface on.

Bed is the furniture of feel of dossing.Sofa can also sleep, so, sofa could also say that a kind of bed.Head of a bed back board device It is that common bed can be made to turn into the device for the bed that can adjust Wo Jiao.Can adjust can abbreviation bed below Wo Jiao bed.Head of a bed back board device is pacified Generally use removable being fixedly connected with the head end that mode is connected to the head end of this bed body and is installed on this mounted in bed head end, Such as it is threadably connected to bed body head end and is arranged on bed head end.Head of a bed back board device is arranged on bed body head end can be with It is used as the supporting leg of bed body.Head of a bed back board device can also be installed in bed head end is positioned over a head end, as long as it relies on wall Still it can be used.Bed has two ends, head end and tail end.Bed head end typically refer to people in bed during sleep head often towards end.Apparatus body is The place of guide, movement parts and backup plate is directly or indirectly installed, it can make cabinet, rack-like etc..Guide is mounted directly In apparatus body.Movement parts are arranged in apparatus body by guide.Backup plate is arranged in apparatus body by movement parts guide. Backup plate is the plate that people is reclined or seat back is leaned on, and it is typically one piece of rectangular slab, and it can be the plate being combined into, and it can also be also energy The elongated plate shortened.

The bed surface of Wo Jiao bed can be adjusted to refer to that padding upper mattress in its bed body spreads what can be slept after cotton-padded mattress sheet or Seats etc. Bed surface.Bed surface can regard a horizontal plane as.The lower end edge of backup plate can get off from apparatus body from the head end for the bed that can adjust Wo Jiao On the bed surface that the bed that can adjust Wo Jiao is placed on different distances, so that, it is placed on bed into different angles with regard to backup plate can be made from bed surface On face.Backup plate and the angulation of bed surface are the angulations that the bed surface for regarding backup plate as a plane and level intersects.Backup plate and bed surface If angulation, which is this face of backup plate, to be rotated around with the intersection of bed surface, backup plate direction bed from bed surface from the position being placed on bed surface The angle turned over when on bed surface is transferred to abut in tail direction.Backup plate, which is placed on, refers to that the lower end edge of backup plate is placed on bed surface on bed surface State is placed on bed surface.Angulation of the end edge from the more remote backup plate of bed head end and bed surface on bed surface is bigger under backup plate, otherwise smaller. The angulation of backup plate and bed surface generally can slightly larger than 90 degree to being slightly less than change between 180 degree.

Backup plate is rotated to be connected by its upper end and movement parts and can just rotated around the axle of this rotation connection.Backup plate is rotatably connected on It can just be moved up and down in movement parts with movement parts along guide.Backup plate has under the free degree that this rotates and moved up and down, backup plate The head end that end edge may get off from apparatus body from the bed that can adjust Wo Jiao is to be placed on the bed for the bed that can adjust Wo Jiao with a distance from different On face.The head end that the lower end edge of backup plate can get off from apparatus body from the bed that can adjust Wo Jiao can adjust Wo Jiao to be placed on a distance from different Bed bed surface on refer to head end that the artificial lower end edge for manipulating backup plate can get off from apparatus body from the bed that can adjust Wo Jiao with not Same distance is placed on the bed surface for the bed that can adjust Wo Jiao.The lower end edge of backup plate can also say it is from apparatus body from getting off in apparatus body Out.Backup plate can adjust the different angle of the tail end direction rotation of Wo Jiao bed with motion around the axial direction that connection is rotated from movement parts Part declines head end that the lower end edge of backup plate can be made to get off from apparatus body from the bed that can adjust Wo Jiao along guide with a distance from different It is placed on the bed surface for the bed that can adjust Wo Jiao backup plate is placed on bed surface into different angles from bed surface.Backup plate is to bed end Direction rotates the rotation for referring to that its lower end edge will be moved to tailstock extreme direction when backup plate is rotated.Usual backup plate is just high in apparatus body In bed surface, uprightly or slightly sloping floor is put to tailstock direction, is declined as long as manipulating backup plate and being rotated to tailstock direction with regard to that will can lean on The lower end edge of plate is placed on bed surface.

Because bed head end of the present invention is provided with head of a bed back board device, it is placed on when by end edge under the backup plate in head of a bed back board device When on bed surface, backup plate be able to angulately must be just placed on bed surface with bed surface, and we can in bed rely on before backup plate and lean on Reclined on the back side or seating is rested.Here the difference illustratively reclined with seating, reclines and requires the angulation of backup plate and bed surface Larger, the weight of human upper is mainly born by backup plate, and seating requires the weight of the smaller human upper of angulation of backup plate and bed surface Amount mainly is pressed on bed surface by bed surface to bear by buttocks.Because the angulation angle of backup plate and bed surface can be by changing backup plate Lower end edge on bed surface from being adjusted with a distance from bed head end, so, this is exactly that a kind of can adjust Wo Jiao bed.Due to internal crucible The lower end edge of backup plate is to be placed directly in very close to each other with bed surface on bed surface during seating of reclining, and therefore, seating of being reclined thereon is all very Comfortably.Again because the backup plate (by movement parts) of internal crucible has guide guiding, either backup plate is placed on bed surface or will leaned on Operation on plate retrieval device body, all due to the guiding for having guide become it is easy and convenient in place, it might even be possible to closed eye one Hand just can complete the operation of backup plate, manipulate backup plate very convenient.Again because the head end of common bed installs this Bed cushion panel assembly Can just turn into can adjust Wo Jiao bed, so, lying or leaning comfortable good for health using easy to operate suitable present invention provides one kind What family used can adjust Wo Jiao bed and its head of a bed back board device.

Guide is the component being play the guiding role to movement parts, and guide can be one and may also be more than one piece.Movement parts are led to Normal only one of which, i.e. movement parts are a movement parts, but movement parts can be several part combinations into a movement parts.Motion The cooperation of part and guide can not be left guide by guide constraint, but can be moved up and down along guide.Movement parts edge is oriented to The motion that part moves up and down typically straight up and down.Movement parts can have rotation in itself along guide up and down motion.Backup plate passes through The rotation connection of its upper end and movement parts, typically backup plate are connected by its upper end by the rotation of an axle and a movement parts Connect, be that backup plate is connected by its upper end by a trunnion axis parallel to end edge under backup plate with a movement parts rotation.Here Described parallel, level is impossible to be absolute, can only be approximate.It is symmetrical that backup plate is connected with the rotation of a movement parts Rotation connection.Symmetrical rotation connection refers to that transverse movement part exists at the middle part of backup plate or backup plate in terms of first direction from tailstock to bed The middle part of movement parts.

We are directed to part and make guide rod, and matched movement parts are made into sliding sleeve, or are directed to part and make guide groove, will Matched movement parts make sliding block, or are directed to part and make the double guide grooves of double rack, and matched movement parts are done into pairs Gear shaft.I.e. guide is that the matched movement parts of guide rod are sliding sleeve or guide is that the matched movement parts of guide groove are sliding Block or guide are that the double matched movement parts of guide groove of double rack are bidentate wheel shafts.So, how backup plate rotates with movement parts ConnectionWhen movement parts are sliding sleeve or sliding block, we generally make a transverse axis set or horizontal sidewards before sliding sleeve or sliding block Axle, transverse axis set rotates the axle being connected to wear with backup plate, and transverse axis is exactly to rotate the axle being connected with backup plate.When movement parts are bidentates During wheel shaft, the axle of this bidentate wheel shaft is exactly that backup plate rotates the axle being connected with movement parts.Guide rod and guide groove can have of different shapes Cross section, as long as there is the sliding sleeve and sliding block coordinated with this section.

The double guide grooves of double rack are exactly two toothed racks, two guide grooves, and exactly two identical racks two are symmetrically the same to lead Groove.Bidentate wheel shaft is exactly that the two end portions of axle are fastenedly connected with the axle of identical gear.A toothed rack one for the double guide grooves of double rack The vertical parallel left side installed in apparatus body of guide groove, is arranged on device another another vertical Parallel Symmetric of guide groove of toothed rack The right of body.The double guide grooves of double rack are typically mounted in apparatus body higher than bed surface towards on the perpendicular in tailstock direction.Bidentate The double guide grooves of wheel shaft and double rack are engaged two gears of the axle and the two guide grooves cooperation bidentate wheel shaft that are exactly bidentate wheel shaft respectively with two Rack, which coordinates, to be engaged.The double guide grooves of bidentate wheel shaft and double rack coordinate it is constrained can not leave it but can along its rotation above and below Motion.

Backup plate, which is placed on bed surface, is reclined or during seating, and lower end is acted on by with bed surface frictional force, and upper end is by passing through movement parts With the effect of the frictional force of guide, it will not typically skid, still, when backup plate and bed surface angulation are larger or smaller in lying or leaning power It may be skidded under effect.Therefore, we set energy lock motion part some position over the guide in head of a bed back board device The locking mechanism decontroled can be unlocked again.Which kind of there is locking mechanism angle to be placed on backup plate on bed surface with regardless of us to recline or sit Lean on, as long as we make locking mechanism lock motion part now position over the guide, backup plate would not skid.Using finishing and Operable locking mechanism unblock relieving is to the locking of movement parts by backup plate retrieval device body.Locking mechanism can be made in movement parts On.Friction lock machine mechanism or locked by pin-and-hole cooperation that locking mechanism can be locked by frictional force Pin-and-hole locking mechanism, can also be that movement parts move the mutual card locking mechanism that they are mutually blocked along guide.

Reclined on internal crucible or during seating, need to just manipulate backup plate and be placed on by the lower drop angle of its rotation on bed surface, can just recline or It is seated against on backup plate and rests.Do not recline or seating after but need to manipulate on backup plate retrieval device body.Although backup plate is simultaneously not bery heavy, Light in order to manipulate, we are set in head of a bed back board device includes the balance backup plate of the components such as balancing weight, fixed pulley and lifting rope The balance weight mechanism of weight.By fixed pulley in apparatus body, one end of lifting rope is lain in movement parts, allows lifting rope to pass through fixed pulley Afterwards the other end hang on balancing weight just into.The many great talents of weight of balancing weight are suitableHave after counterweight, hand, which holds backup plate lower end, to be made to lean on When turning outside plate, allow most of weight of backup plate top and movement parts to be balanced, but can also decline just under deadweight.So, Usual balancing weight weight is about the weight of half or so backup plate.Half or so backup plate weight is balanced, and is manipulated just light during backup plate .In order to prevent balancing weight whipping from hitting, we set balancing weight guide rod to be oriented to for balancing weight in balance weight mechanism again.

To make backup plate recline or seating is comfortable, we are in backup plate above one layer of soft bullet thing of setting i.e. in backrest surface.Soft bullet The thing such as last plastics of elasticity bubble, cotton, fabric, cloth.For keep backup plate backrest surface cleaning we set backup plate overcoat to be enclosed on to lean on It can often be changed in plate backrest surface and often wash holding cleaning.In order to it is attractive in appearance we can also be covered outside backup plate print off or embroider out beauty figure Draw.Pillow can be set in the upper end of backup plate backrest surface as needed, and also can be set can move the pillow of displacement, certainly, It can cover and be set as nylon adherent buckle to glue puts pillow outside backup plate.The bed surface of some is very soft, in order to mitigate end edge pair under backup plate The pressure Strong of bed surface, we set pressure reductor in backup plate lower end.Pressure reductor is rotated with backup plate lower end and is connected.There are pressure reductor, backup plate Lower end edge be placed on bed surface be exactly under backup plate end edge be placed on by pressure reductor on bed surface.There is pressure reductor, backup plate is placed on bed The lower end edge on face being exactly backup plate is placed on being so placed on bed surface on bed surface by pressure reductor.It can thus reduce under backup plate Pressure Strong of the end edge to bed surface.

In family to use double bed, sleeping the same time between, often each has his likes and dislikes, and prostration is reclined the need for having the need for having more, To meet this individual needs, we will can adjust the head of a bed back board device of Wo Jiao double bed to make double point of head of a bed backup plate Device.Double point of head of a bed back board device be have apparatus body include the structures such as two sets of guides, movement parts, backup plates Part matches somebody with somebody the head of a bed back board device that can individually use being combined into.

Can adjust Wo Jiao bed structure it is simple, using easy to operate, common bed, which loads onto head of a bed back board device and just turns into can adjust, to crouch The bed at angle, suitable family expenses.There is the bed that can adjust Wo Jiao in family, just can be by the backup plate in head of a bed back board device with different demands Angle, which is placed on bed surface, reclines or seating is rested, and you, which also cosily can recline or be seated against, sees TV on this bed Play mobile phone.This bed patient old man preferably is used, and them can be allowed to rest more preferably more healthy.It is willing to people all over the world's therefore bed life Obtain finer！
