Fig. 1 is an axonometric chart of having used the bed of stay locking mechanism of the present invention, and Fig. 2 is a front view.Symbol 1 represent synoptically the bed, the 2nd, the bedstead that can above base station 3, carry out lifting, the 4th, be divided into a plurality of 4a of portion, 4b, 4c, 4d made fluctuating posture the bed base plate.Symbol 5a is the first speed plate, and 5b is the foot baffle plate, and 6a is the handheld operation device that the Up-and-down of bed base plate 4 is operated, and 6b is the nursing procedure device that care-givers such as Nursing Administrator operate the Up-and-down of bed base plate 4.Symbol 7 is parts that side of the present invention hurdle is represented synoptically.More than the action of the bed 1 of explanation is very tangible, the Therefore, omited explanation.
Side of the present invention hurdle 7 roughly is made of side hurdle body 8 and portion of mechanism 9, is being provided with the installing frame 10 that is used to be installed on the bedstead 2 in the portion of mechanism 9.Then describe portion of mechanism 9 in detail, but Fig. 3, Fig. 4 of reference this moment see that from face side and rear side side hurdle 7 unloads the axonometric chart of back state from bed 1 respectively, Fig. 5 is the axonometric chart of seeing from face side under the state after the front cover with side hurdle body 8 and portion of mechanism 9 unloads, and Fig. 6 is the enlarged drawing of the major part of Fig. 5.Fig. 7～Fig. 9 is the amplification view of the major part dissectd along A-A line among Fig. 6.
Promptly, but side of the present invention hurdle utilization can make the sidepiece knee-action of side hurdle body 8 at bed 1 around above-below direction devices spaced apart configuration and axle 11a, the 11b corresponding with the length direction of bed 1, the 1st stay 13 that 12a, 12b rotate and the 2nd stay 14, and can fix in lifting position.In the fixable mechanism of this lifting position is stay locking mechanism 15 among the present invention.
So as shown in the figure the 1st stay the 13, the 2nd stay 14 is between the pair of links arm 16,17 that disposes about respectively support unit 18,19 to be given be combined into.In this structure, the pair of links arm 16 of the 1st stay 13 is configured in the outside of the pair of links arm 17 of the 2nd stay 14.
The support unit 19 of the 2nd stay 14 is tabular, is supported with stop pin 21 by supporting frame 20 on this support unit 19.
On the other hand, the support unit 18 of the 1st stay 13 form pitman arm 17 across the 2nd stay 14,17 of pitman arms to outstanding crooked tabular of support unit 19 directions.And on support unit 18, being fixed with utilization axle 22 rotating action bars 23, the top of action bars 23 is formed with plate-like portion 24, is formed with bar-shaped 26 on the supporting frame 25 that is based on this plate-like portion 24.Also the locking plate 29 that can wind by axle 28 rotations of supporting frame 27 supportings is arranged at support unit 18 upper supports.The described axle 28 of locking plate 29 is positioned at the centre position of above-below direction, is formed with the crook 30 that can engage with described stop pin 21 on the top of locking plate 29, and is formed with forked portion 31 in the bottom.There is described bar-shaped 26 and on this forked portion 31, can engage with relatively moving.In addition, on locking plate 29, be provided with torsion-coil spring 32, to the direction application of force that engages with stop pin 21.Thereby be formed with when action bars 23 is carried out rotating operation in the front side of the plate-like portion 24 of action bars 23 and limit rotation abutting part 33 that the restriction of tabular support unit 19 butts of described the 2nd stay 14 is rotated.Symbol 34 is installing components of installing to side hurdle body 8.
The portion of mechanism 9 that is made of above structural element can be covered the front cover 35 that action bars 23 is operated.
In above structure, when making the 8 parallel risings of side hurdle body when the rotation that utilizes the pitman arm 16,17 that constitutes the 1st, the 2nd stay 13,14, as Fig. 5～Fig. 7, shown in Figure 10, the crook 30 of locking plate 29 engages with stop pin 21 because of the application of force of torsion-coil spring 32, thus, the 1st stay 13 and the 2nd stay 14 can not produce and relatively move, and stop pitman arm 16,17 to descend, therefore, the state of side hurdle body 8 after the sidepiece of bed base plate 4 is retained rising.
Then make side hurdle body 8 drop to the occasion of favorite places, if when making the direction of arrow of action bars 23 in Fig. 7 be the clockwise direction rotation, be located at bar-shaped the 26 urge lock sheet 29 on one side that in forked portion 31, relatively moves on the supporting frame 25 of plate-like portion 24 of action bars 23 on one side, make locking plate 29 overcome the application of force of torsion-coil spring 32 and to counterclockwise rotating.Like this, when locking plate 29 when counter clockwise direction is rotated, as shown in Figure 8, the crook 30 of locking plate 29 is with regard to release lock rationed marketing 21, engaging is disengaged.
So, when the crook 30 of locking plate 29 was disengaged with engaging of stop pin 21, the 1st stay 13 and the 2nd stay 14 just can relatively move, and pitman arm 16,17 is rotatable to descend, from Figure 11 through the state of Figure 12, Figure 13 and can be to favorite places shown in Figure 14.Figure 15 is an axonometric chart of seeing the side hurdle 7 of Figure 12 state from rear side, and same, Figure 17 is an axonometric chart of seeing the side hurdle 7 of Figure 14 state from rear side, and Figure 16 is an axonometric chart of seeing the side hurdle 7 of Figure 14 state from face side.
So, in the present invention, action bars 23 and locking plate 29 be not by intermediate members such as the such intermediate connecting rods of above-mentioned conventional art and directly transmit operating physical force by bar-shaped 26 with engaging of forked portion 31, so can reliably and successfully operate.In addition, owing to do not need intermediate member,, reduce cost so can reduce the part number.
In this example, because the front side at the plate-like portion 24 of action bars 23 is formed with limit rotation abutting part 33, surpass the rotating operation that needs so can prevent action bars 23, can prevent to be subjected to surpassing the damage that necessary load produces because of locking plate 29 organize factors such as grade.
The side hurdle body 8 of collecting state will be become user mode, mention side hurdle body 8 and just can make the pitman arm 16,17 that constitutes the 1st stay 13 and the 2nd stay 14 rotate rising, body 8 therewith parallel risings in side hurdle can become the use location.
If side hurdle body 8 rises to the use location, then the crook 30 of locking plate 29 is crossed stop pin 21 and is engaged, as mentioned above, the 1st stay 13 and the 2nd stay 14 can not produce and relatively move, so stop pitman arm 16,17 to descend, therefore, the state after body 8 sidepieces at bed base plate 4 in side hurdle are retained rising can be used safely.
But, in the snap action of above-mentioned crook 30 and locking plate 21, this situation is arranged sometimes: the motion of crook 30 is former thereby hindered because of some, for example as shown in Figure 9, produce the state that crook 30 not exclusively engages with stop pin 21 halfway, become so-called half fastening state.Just do not use if know this half fastening state, side hurdle body 8 will inadvertently fall, and is dangerous.
To this, in this example, under the crook 30 of locking plate 29 and states that stop pin 21 normally engages, the front portion of action bars 23 is in the position on the surface that does not protrude in front cover 35, under the state of undesired engaging, the front portion of action bars 23 is outstanding from cover 35, therefore, confirm that by eyes this action bars 23 is outstanding from front cover 35, just can confirm half fastening state from the outside, operation is so that normal engaging just can form safe user mode thus once more.
At this moment, for example if form different colours (diagram is omitted) part in when operation from outstanding action bars 23 side surface part of front cover, then available eyes are confirmed the difference of color, thereby can be easy to confirm action bars 23 outstanding from front cover 35 with eyes.
In the example of above explanation, though be provided with bar-shaped portion, be provided with forked portion 31 in locking plate 29 sides in action bars 23 sides, also can forked portion be set on the contrary in action bars 23 sides, in locking plate 29 sides bar-shaped portion is set.
Practicality on the industry
As mentioned above, the present invention has following advantage:
1. the operating physical force that produces of action bars is directly passed to locking plate by forked portion and the holding section that engages with it movably, removes and operates so can carry out reliably the engaging of locking plate release lock rationed marketing;
2. owing between action bars and locking plate, do not clamp the parts such as intermediate connecting rod, thus can operate reliably and reduce number of components, thus can reduce cost;
3. in the crook of utilizing action bars to make locking plate during with operation that stop pin engages, whether outstanding by the front of confirming action bars with eyes, just can know whether from the outside be stuck reliably or no be incomplete engaging midway. In this occasion, if outstanding side surface part forms the different colours part from the front of lid when action bars is operated, just confirm with eyes easily;
4. if at action bars the limit rotation abutting part is set, then can prevent damage of the organize factor that the imperative operation because of action bars produces etc.;
5. the lock out action of the crook of locking plate and stop pin is the structure that relatively moves and stoped to the 1st stay and the 2nd stay, so compare the free degree height of the setting position of action bars with the structure on the bracket for mounting that stop pin is located at bedstead.
