Specifically, a plurality of moving wheels 310 are provided at a lower portion of the supporting unit 300 to move the supporting unit 300, and in the present embodiment, four moving wheels 310 are provided in a frame having a rectangular shape. The support unit 300 simultaneously moves the placing unit 100 by driving the moving wheels 310 or an external force applied from the outside to perform a function of a wheelchair or a moving bed.
In the present invention, as shown in the drawing, the supporting unit 300 is formed of a plurality of frames and is partially inclined, so that the height of the placing unit 100 in the vertical direction can be adjusted, and thus, the user can use the same at a height required by the user.
In which the height adjustment of the above-described support unit 300 may be manually adjusted by a direct operation of a user or automatically operated by a separate driving motor.
On the other hand, at least a part of the inclination adjusting unit 200 is connected to the placing unit 100 at the supporting unit 300, and the posture is adjusted in the first form or the second form by selectively adjusting the inclination degree of the placing unit 100.
Specifically, a part of the reclining unit 200 is coupled to the backrest portion 110 and the bed head portion 130 while being tilted on the support unit 300 to tilt the backrest portion 110 upward, and is adjusted to a first mode in which the bed head portion 130 is tilted on the backrest portion 110 or a second mode in which the backrest portion 110 and the bed head portion 130 are substantially horizontal. In the present invention, the tilt adjusting unit 200 generally includes an expansion part 210, a rotation link 220, a pitch adjusting part 240, and an auxiliary link 230.
In the present invention, as shown in the drawing, the rotation link 220 is formed long in the support unit 300, is disposed at a lower portion of the placement unit 100 along the longitudinal direction, has a first rotation axis a1 at a middle portion along the longitudinal direction, and is rotatably coupled to the backrest portion 110. One side of the rotation link 220 is connected to the expansion and contraction part 210 described later.
In this case, the expansion unit 210 is installed on the support unit 300 or the center support unit 120, and at least a portion of the expansion unit 210 is connected to one side of the rotation link 220 in an expandable and contractible manner, so that the rotation link 220 can be rotated about the first rotation axis a1 by expansion and contraction.
In the present embodiment, the telescopic part 210 is normally formed in a brake type to rotate the rotation link 220, but a rotation motor may be formed to rotate the rotation link 220.
As described above, the rotation link 220 may adjust the inclination degree of the backrest portion 110 by rotating the telescopic portion 210 about the first rotation axis a1 and pushing the backrest portion 110 by at least partially contacting the lower surface of the backrest portion 110.
On the other hand, the other end portion of the rotating link 220 is rotatably coupled to the back surface of the head portion, and as the rotating link rotates about the first rotating shaft a1, a part of the rotating link 220 contacts the back surface of the backrest portion 110 and pushes the head portion 130 at the backrest portion 110, thereby tilting the head portion 130.
In the present embodiment, as shown in the drawing, the other end portion of the rotating link 220 is bent in an upper direction, so that a second rotating shaft a3 is provided on the back surface of the bed head 130 and is rotatably coupled to the back surface of the bed head 130.
Therefore, when the rotating link 220 rotates about the first rotating shaft a1, the bed head 130 is pushed to incline the backrest 110 and the bed head 130 to form the first configuration before contacting the backrest 110. Thereafter, the backrest part 110 is tilted upward in a state where the backrest part 110 is in contact with a part of the rotating link 220.
The bed head 130 has the second rotation axis A3 and is coupled to the rotation link 220 in a penetrating manner by having a size relatively larger than that of the second rotation axis A3 so as to smoothly move when coupled to the rotation link 220, and interference can be prevented by securing a predetermined level of freedom when the bed head 130 is pushed at one end of the rotation link 220.
As described above, the rotating link 220 is formed long and selectively rotates about the first rotating shaft a1, and the other end portion of the rotating link 220 is connected to the bed head 130 to adjust the degree of inclination of the bed head 130 and the backrest 110 by rotating in the first or second state.
On the other hand, the pitch adjusting unit 240 is disposed at a predetermined distance from the first rotation axis a1 at the lower portion of the backrest 110, and is coupled to a movement axis a2 formed at the rotation link 220 so as to rotate the rotation link 220 without departing from a predetermined range.
Specifically, the pitch adjusting unit 240 is formed to protrude downward from the backrest portion 110, and is disposed between the first rotation axis a1 and the second rotation axis A3. At this time, the pitch adjusting part 240 is coupled to the moving axis a2 formed at the rotation link 220 in a penetrating manner, and has a slit-shaped hole relatively larger than the moving axis a2, thereby adjusting the position of the rotation link 220 within a predetermined angle range.
That is, as shown in fig. 6, when the rotation link 220 rotates about the first rotation axis a1, the pitch adjustment part 240 is disposed on L1 as a virtual extension line in the second form and disposed on L2 as a virtual extension line in the first form. At this time, the pitch adjusting part 240 determines the moving radius of the moving axis a2 and determines the moving radii of the L1 and L2 according to the size of the hole formed in the slit form.
As described above, the distance adjusting unit 240 is disposed on the backrest portion 110 so as to pass the moving axis a2 therethrough, and is configured to be rotatable within a predetermined radius without disengaging the rotating link 220 that rotates about the first rotating axis a1, thereby tilting the backrest portion 110 in the first form or the second form.
On the other hand, the auxiliary link 230 is formed to protrude from the rotating link 220 toward both sides in the width direction, and the distal end portion of the auxiliary link 230 is rotatably coupled to the wing 160.
Specifically, the swivel link 220 is connected to the bed head 130 to tilt the swivel link 220, and the auxiliary link 230 is connected to the wing 160 to tilt the wing 160 in the backrest 110.
Specifically, as shown in the drawing, the auxiliary link 230 is formed to protrude in the width direction on the rotation link 220, and the distal end portions of the auxiliary link 230 are bent upward and have third rotation axes a4, respectively, and are rotatably coupled to the rear surfaces of the wing portions 160.
When the rotation link 220 rotates, the auxiliary link 230 adjusts the distance from the backrest 110 in conjunction with the adjustment of the distance between the rotation link 220 and the backrest 110, and pushes the wing 160 by pushing the both end portions upward.
At this time, since the auxiliary link 230 is also rotatably coupled to the wing 160 like the bed head 130, the wing 160 is moved forward by the rotation of the rotating link 220 and the wing 160 is tilted in the backrest 110.
In the present embodiment, as shown in the drawing, the auxiliary link 230 is integrally formed with the rotating link 220 and protrudes to both sides, and the rotation of the rotating link 220 adjusts the distance from the back surface of the backrest 110, thereby tilting the wing part 160 together with the head part 130.
As described above, the reclining unit 200 according to the present invention includes the telescopic part 210, the swivel link 220, the interval adjusting part 240, and the auxiliary link 230, and the swivel link 220 is swiveled by the tilting degree of the telescopic part 210, and forms the first mode of tilting the bed head part 130 and the wing part 160 by adjusting the distance between the backrest part 110 and the swivel link 220 according to the swiveling of the swivel link 220.
That is, as shown in fig. 3 and 4, a part of the rotating link 220 is rotated by the telescopic part 210 and is in a state of being in contact with the backrest part 110, and at this time, the bed head part 130 and the wing part 160 are inclined upward at the backrest part 110 by the rotating link 220 and the auxiliary link 230, respectively, to form the first form.
Thereafter, as shown in fig. 5, the rotation link 220 is further rotated, so that the backrest portion 110 can be tilted upward while the backrest portion 110 is tilted upward in a state where the first form is maintained.
Next, the structure of the inclined bed of the present invention including the form fixing part 250 is briefly observed with reference to fig. 7 to 10.
Fig. 7 is a schematic view showing the structure of the form fixing unit 250 in the inclined bed of fig. 1, and fig. 8 is a conceptual view schematically showing the state in which the form fixing unit 250 of fig. 7 is operated.
Also, fig. 9 is a view illustrating a state in which the backrest part 110 of the setting unit 100 in the inclined bed of fig. 1 is inclined toward the upper part in the second state, and fig. 10 is a side view briefly illustrating a state in which the inclination adjusting unit 200 in the inclined bed of fig. 1 inclines the backrest part 110 in a state in which the bed head 130 is maintained in the second state.
Looking at the drawings, the above-described tilt adjusting unit 200 of the tilting bed of the present invention may further include a form fixing part 250.
When the rotation link 220 rotates, the form fixing unit 250 maintains one of the first form and the second form when the backrest 110 is inclined upward. Specifically, the form fixing unit 250 is provided on the back surface of the backrest 110, and is fixed to selectively adjust a distance from the backrest 110 by the rotating link 220 to maintain the second form.
That is, when the rotating link 220 rotates about the first rotating shaft a1, the form fixing unit 250 fixes the change in the distance between the back surface of the backrest portion 110 and the rotating link 220, so that the rotating link 220 and the auxiliary link 230 can push only the backrest portion 110, not the bed head portion 130 and the wing portion 160, respectively.
In the present invention, the form fixing unit 250 includes a fixing member 252 formed in a long shape to slide on the back surface of the backrest 110, and at least a part of the fixing member is selectively inserted between the backrest 110 and the rotating link 220, and an operation unit 254.
As seen in the drawing, the fixing member 252 is disposed adjacent to the interval adjusting part 240, and at least a portion of the fixing member 252 is inserted between the rotating link 220 and the backrest part 110. At this time, the fixing member 252 is formed in a shape of "Contraband" to prevent interference with the moving axis a2, and slides on the back surface of the backrest 110.
In the present embodiment, the fixing member 252 is slid on the backrest part 110 and selectively inserted between the rotating link 220 and the backrest part 110, and particularly, the fixing member 252 is selectively disposed between the moving axis a2 and the rotating link 220 to adjust the distance between the rotating link 220 and the backrest part 110.
On the other hand, the operation unit 254 is formed long and rotatably provided on the backrest portion 110, one side of the operation unit 254 is connected to the fixing member 252, the other side thereof is formed with a handle, and the center portion thereof is rotatable with the backrest portion 110. The fixing member 252 may be slid by operating the handle, so that the fixing member 252 may be inserted between the backrest portion 110 and the rotating link 220.
As described above, the form fixing unit 250 includes the fixing member 252 and the operation unit 254, and is fixed so as to selectively adjust the distance between the rotating link 220 and the backrest 110, and even if the rotating link 220 rotates about the first rotation axis a1, the bed head 130 does not tilt in the first form, but the backrest 110 can be tilted upward while maintaining the second form.
In more detail, as shown in fig. 8 (a), the operation unit 254 is operated to slide a part of the fixing member 252, thereby removing a unit for limiting the movement of the moving shaft a2 provided to the rotating link 220. At this time, the distance between the rotating link 220 and the backrest 110 is shortened according to the rotation of the rotating link 220, and the bed head 130 is inclined upward in a first mode.
On the contrary, as shown in fig. 8 (b), in the case where the fixing member 252 is disposed between the moving axis a2 provided in the rotating link 220 and the backrest portion 110 by sliding the operating unit 254, even if the rotating link 220 rotates, the second form can be maintained because the distance between the rotating link 220 and the backrest portion 110 can be maintained.
As described above, in the case where the rotating link 220 rotates in a state where the second form is maintained, as shown in fig. 9 and 10, the backrest part 110 is inclined upward in the second form.
As described above, the reclining bed of the present invention can selectively tilt the backrest part 110 upward while maintaining one of the first mode in which the backrest part 110 and the head part 130 are tilted by the reclining adjustment unit 200 and the second mode in which the head part 130 and the backrest part 110 are substantially horizontal.
