The 9th, by the bearing support of forming synthetic resin, make the through hole 9a of above-mentioned link axial region 3a perforation in central part setting, and be formed for receiving the cylindric container 9b of stationary cylinder shape bearing 10 in connection ball 6 sides of this through hole 9a.In addition, 2 places are set on diagonal for passing through the flight 9c of the fastening fixing axle cover 12 described later of screw 13.
The 12nd, the axle cover that shown in protection Fig. 2, above-mentioned Hooks coupling universal coupling 1 and screw rod 3 adhere to prevent dust; one end forms the axial region cover 12a of portion of the outer cover 3d that covers screw rod 3; the other end forms the 12b of splice housing portion of the planar expansion of hemisphere that covers Hooks coupling universal coupling 1, at its sidewall, the fastener hole 12c of 2 places for making to connect at the fastening screw 13 of the flight 9c of bearing support 9 is set.
The 16th, by the leading-off rods cover cylindraceous of forming synthetic resin, the E that covers above-mentioned sliding axle 2 encircles the axial region periphery between 14 and 15.
The 17th, the crank handle that above-mentioned sliding axle 2 is rotated, this handle 17 is at the front end of the axial orthogonal fixing handle body 18 of cardinal extremity and sliding axle 2, with the mode mounting handle handle 27 that can rotate freely.
At the cardinal extremity of above-mentioned handle body 18, form the hexagonal embedded hole 18a identical with the profile of sliding axle 2, insert sliding axles 2 from inner side via leading-off rods cover 16, under the state of E ring 15 and the suitable place butt of embedded hole 18a periphery, fastening fixing via packing ring 20 by screw 21.In addition, in appearance for hidden screw 21, labelled 22.In addition, at the approximate central part of the table side of handle body 18, when forming handle 25 and falling, the container 18b of approximate concavity was seen in foldable side.And front end formation handle shaft 26 can be similar to the slot part 18d of the angle fluctuating of 90 degree, and, the fastener hole 18e that pin 25 is connected offered at its sidewall.In addition, in the approximate center of inner side, the outstanding Embedded Division 18c that is formed for embedding backboard 28 described later.
In addition, be configured in the 18b of the container of handle body 18 under the state of the above-mentioned handle 27 of bending storage, while being pressed into handle body 18, the E ring 14 of sliding axle 2 can be received into connect the end face 4f butt of body 4 till.
Above-mentioned handle shaft 26 is metal systems, and base end part is divided into flat, in its suitable place, fulcrum hole 26b is set, and the swivelling chute 26a that is whittled into concavity on circumference is set at front end.
Above-mentioned handle 27 is formed by synthetic resin, the front end of handle shaft 26 is inserted to the embedded hole axially arranging, the align position of this swivelling chute 26a and fastener hole 27b, by fastening in the mode of inserting pin 30 front ends in swivelling chute 26a, can rotate freely handle 27 and is installed to handle shaft 26.
For the handle 27 that keeps in arbitrary position can rising and falling by the fastener hole 18c insertion pin 25 of the fulcrum hole 26b to handle shaft 26 and handle body 18, spring 23 is fixed to handle body 18 inner sides by screw 24.The 29th, be installed to the labeling of handle 27.
Above-mentioned backboard 28 forms the through hole 28a that above-mentioned leading-off rods cover 16 is connected on top, and is provided for embedding the embedded hole 28b of the Embedded Division 18c that is fixed to above-mentioned handle body 18 at approximate central part.
According to above formation, following action is described.First, hand-held handle body 18, with axial region cover 12a with connect the be in line mode of shape of body 4 and leading-off rods cover 16, after hand grip 27 is rotated, when the linking department 4d that connects body 4 rotates along the engaging cylinder 5a of portion of the coupking shaft 5 in engagement groove 4c, handle body 18 and sliding axle 2 (live axle) rotation.
Then, as shown in Figure 2, from handle body 18 antagonistic springs 23 and the both sides of hand grip 27 make this handle 27 take pin 25 as fulcrum 90-degree rotation.Under this state, after handle 27 rotations, handle body 18, sliding axle 2 (live axle) and connection body 4 make to connect ball 6 via coupking shaft 5 and rotate.Thereby, the link axial region 3a (driven shaft) of this connection ball 6 and screw rod 3 is linked by fixing pin 8, therefore, the power of sliding axle 2 (live axle) transmits to the link axial region 3a (driven shaft) of screw rod 3, via the driven device linking with screw rod 3, make bottom elevation, the bending of bed.
Here, illustrated that the connection shaft 3a (driven shaft) of sliding axle 2 (live axle) and screw rod 3 is not straight line shape, and the situation of rotating to form the state of predetermined angular.In the linking department 4d by connection body 4 and cover 7 spaces that form, be that the situation that the situation of the state that is rotatably assorted is the state that is rotatably assorted with the snap-latch piece 6b of connection ball 6 that is engaged to this engaging cylinder 5a of portion is combined owing to connecting the engaging cylinder 5a of portion of the coupking shaft 5 in the engagement groove 4c of linking department 4d of body 4, therefore, by making linking department 4d and the snap-latch piece 6b clamped position variation of the engaging cylinder 5a of portion of butt engaging respectively, even if there is predetermined angular, also can transmit its rotating power out of questionly.
As mentioned above, Hooks coupling universal coupling of the present invention possesses: one end is connected with the power source of motor, handle etc. and the other end forms the sliding axle 2 as live axle of linking department 4d and connects body 4; One end is connected with driven device and the other end is provided with the connection ball 6 as driven shaft and the screw rod 3 of snap-latch piece 6b; The criss-cross coupking shaft 5 as connecting member engaging in sense of rotation with above-mentioned linking department 4d and snap-latch piece 6b; Under the state that this coupking shaft 5 engages in sense of rotation with above-mentioned linking department 4d and snap-latch piece 6b, embed and support the cover 7 as fixed unit of above-mentioned linking department 4d periphery, therefore, can light weight and simply form the goods that provide assembling easy and cheap.
In addition, above-mentioned linking department 4d, above-mentioned coupking shaft 5 and above-mentioned snap-latch piece 6b are formed by synthetic resin material, therefore the slip sound can as far as possible reduce the lifting of bed time, when bending, the generation of vibration, even also can not get rusty because of corrosion while use for a long time, also without the maintenance of regularly oiling etc.
And, under state in handle 27 bendings are received into the container 18b of handle body 18, press after handle body 18, the E ring 14 of sliding axle 2 can be received into connect the end face 4f butt of body 4 till, therefore the breakage and the accident that, can prevent from not using time, contact outstanding handle 27 and cause.
In addition, as other embodiments of the present invention, also can change the position of bearing 10 and isolator 11.
Embodiments of the invention have more than been described, according to above-mentioned explanation, those skilled in the art can be realized various replacement examples, revise or distortion, and the present invention is included in aforesaid various replacement examples in the scope that does not depart from its spirit, revises or distortion.
As mentioned above, the present invention can provide and can make and assembling is easy to cheap goods by simply forming, and makes in the time of the lifting of bed, do not slide as far as possible when bending sound, vibration and long-time use also can not get rusty as far as possible.
