As shown in the figure, pillar part 2 (this example is the left pillar parts 2 of Fig. 1) is connected with mechanism supports parts 5 with the form that the activity supporting point 8 that can rotate rotates.On the parts 9 that are arranged on the pillar part 2, be formed with connecting hole 10, be formed with rake 11 at connecting hole 10 cross sides of parts 9.
On the other hand, the position that is in the connecting hole 10 when holding up posture with pillar part 2 is corresponding, latch 12 can be advanced and retreat and is supported on the mechanism supports parts 5 (this example for moving up and down), and this latch 12 is compressed spring 13 such as helical spring towards the application of force of direction below promptly among the figure of advancing.As shown in the figure, the outstanding small diameter part on the top of latch 12 engages with above-mentioned connecting hole 10.Symbol 14 is cylindrical body that the latch 12 that can advance and retreat is supported.Be formed with operating position 15 at the rear portion of latch 12 (this example is top), on this operating position 15, be formed with the slotted hole 16 of above-below direction.
On the other hand, remove action bars 6 activity supporting point 17 that can rotate and be supported on rotationally on the mechanism supports parts 5, the lower portion 6d of this releasing action bars 6 exposes from above-mentioned closing any opening portion 7 as the operating position.
In addition, the upper portion of removing action bars 6 is outstanding towards the top, is formed with recess 19 in the left side of right side teat 18.
The left end side of this external releasing action bars 6 is provided with pin 20, and this pin 20 engages with the slotted hole 16 of the operating position 15 of above-mentioned latch 12.
Be provided with the Lock Part 22 that moves along left and right directions among the figure in the slotted hole 21 that left and right directions in the drawings forms on the top of mechanism supports parts 5, be formed with and remove the teat 23 of teat 18 butts of action bars 6 at the downside of Lock Part 22, and be formed with the teat 24 of operation usefulness at upside.Lower surface at the mechanism supports parts 5 of the left and right sides of Lock Part 22 is formed with teat 25, is used for being kept when Lock Part 22 moves to left and right sides, is formed with corresponding concave part 26 with it on Lock Part 22.
In above formation, Fig. 5 is that pillar part 2 is in and holds up posture, the top of latch 12 engages with connecting hole 10 under the application of force of spring 13, therefore pillar part 2 is retained with respect to mechanism supports parts 5 and that is to say with respect to upper cross bar parts 1u and can not rotate around fulcrum 8 that the side horizontal bar remains on the extreme higher position with upper cross bar parts 1u under pillar part 2 erected state.In addition, among Fig. 5, Lock Part 22 maintains the state of Figure 11, and therefore removing action bars 6 is in exercisable state.
As shown in Figure 6, when Lock Part 22 is moved towards right and become the state of Fig. 6, Figure 12, with teat 23 butts of Lock Part 22 owing to remove the teat 18 of action bars 6, push towards the top, also can't operate fully and remove action bars 6 even therefore will remove the operating position 6d of action bars 6.
Like this, in this example, removing the circular opening portion 7 that forms on the tabular mechanism supports parts 5 of the operating position 6d tegmentum of action bars 6 surrounds and is difficult to and be operated between being not intended to, even the situation of operating between occurring in addition being not intended to also can stop by locked parts 22, realize dual fail-safe thus.
When making the side horizontal bar become that the folding and unfolding state just makes pillar part 2 rotate to descend when upper cross bar parts 1u is descended, with Lock Part 22 in the figure left to moving, after becoming the disarm state of Fig. 5, Figure 11, with hand to the operating position 6d that in closing any opening portion 7, exposes towards above pushing, then remove action bars 6 and rotate around fulcrum 17 clockwise direction in the figure.Along with this rotation, pin 20 moves towards the top, and this pin 20 moves the upper end of slotted hole 16, thus latch 12 in the application of force that overcomes spring 13 under the drive of operating position 15 and towards above mobile.Like this, as shown in Figure 7, the top of latch 12 retreats and breaks away from connecting hole 10.
Under this state, pillar part 2 is turned to Fig. 9 from Fig. 8, thereby can utilize parallel linkage to make the parallel decline of upper cross bar parts 1u.
On the contrary, the upper cross bar parts 1u of decline state is risen, arrive the state of Fig. 8 from Fig. 9 after, upper cross bar parts 1u is risen, that is to say in Fig. 8 and further pillar part 2 is relatively rotated toward the clockwise direction, then as shown in figure 10, the rake 11 of parts 9 retreats latch 12, in latch 12 and connecting hole 10 moment corresponding, latch 12 is engaged in the connecting hole 10 under the effect of spring 13, thereby automatically becomes fastening state shown in Figure 5 then.
From Figure 10 as seen, among the present invention, owing between releasing action bars 6 and latch 12, be provided with play mechanism, play mechanism constitutes by being arranged on the slotted hole 16 on the operating position 15 and being arranged on the pin of removing on the action bars 6 20 in this example, so latch 12 can move under the situation that releasing action bars 6 is not applied external force with its operating position 15.
Therefore under the state of Fig. 8, if Lock Part 22 is on the position of Fig. 6, Figure 12, latch 12 also can retreat from connecting hole 10 in the same manner with the state of Figure 10, therefore identical with Figure 10, the rake 11 of parts 9 retreats latch 12, in latch 12 and connecting hole 10 moment corresponding, latch 12 is engaged in the connecting hole 10 under the effect of spring 13, thereby automatically becomes fastening state shown in Figure 5 then.
Like this, in the present invention,, in addition the locking of Lock Part 22 can be set in operating state when the state that is keeping with erected state descends, can improve security when pillar part 2 need be operated removing action bars 6.
In addition, in above-mentioned first example, represented to remove the play mechanism that the pin 20 on the action bars 6 constitutes, shown in the second following example, can use suitable play mechanism in addition by being arranged on the slotted hole 16 on the operating position 15 and being arranged on.
Figure 13～Figure 15 is the maintaining body of the folding side horizontal bar of expression the present invention second example.In this example, only above-mentioned play mechanism prevents that with releasing mechanism is different with first example, and corresponding inscape is put on identical symbol.
As Figure 13～shown in Figure 15, pillar part 2 is connected with mechanism supports parts 5 with the form that the activity supporting point 8 that can rotate rotates.On the parts 9 that are arranged on the pillar part 2, be formed with connecting hole 10, be formed with rake 11 at the position of connecting hole 10 cross sides of parts 9.
The position that is in the connecting hole 10 when holding up posture with pillar part 2 is corresponding, latch 12 can be advanced and retreat and is supported on the mechanism supports parts 5 (this example for moving up and down), and this latch 12 is compressed spring 13 such as helical spring towards the application of force of direction below promptly among the figure of advancing.As shown in the figure, latch 12 is engaged with above-mentioned connecting hole 10 by the small diameter part outstanding on the top in the same manner with first example.Symbol 14 is cylindrical body that the latch 12 that can advance and retreat is supported.Be formed with operating position 15 at the rear portion of latch 12 (this example is top), on this operating position 15, be formed with the recess 27 of transverse opening.
Remove action bars 6 activity supporting point 17 that can rotate and be supported on rotationally on the mechanism supports parts 5, the lower portion 6d of this releasing action bars 6 exposes from the closing any opening portion 7 that is arranged on the mechanism supports parts 5 as the operating position.
In addition, the upper portion of releasing action bars 6 forms step-like on left and right directions, and the left side forms protruding side, and the right side forms recessed side 19.
Be provided with pin 20 in the left end side of removing action bars 6, this pin 20 engages with the recess 27 of the operating position 15 of above-mentioned latch 12.Symbol 31 is guiding parts.
In the mechanism supports parts 5, Lock Part 22 can be supported on the upside of the upper portion of removing action bars 6 movably along left and right directions among the figure, upside at Lock Part 22 is provided with operation teat 29, the slotted hole 21 of the left and right directions that this operation is provided with by mechanism supports parts 5 tops with teat 29 is projected into the outside of mechanism supports parts 5, Lock Part 22 can move at left and right directions like this, can carry out move operation with teat 29 by operation.
In this example, Lock Part 22 be compressed springs such as helical spring 30 towards left to the application of force.The top downside of this external Lock Part 22 is formed with the teat 28 with the upper portion butt of removing action bars 6.
In above formation, Figure 13 B-C post parts 2 are in holds up posture, the top of latch 12 engages with connecting hole 10 under the application of force of spring 13, therefore pillar part 2 is retained with respect to mechanism supports parts 5 and that is to say with respect to upper cross bar parts 1u and can not rotate around fulcrum 8 that the side horizontal bar remains on the extreme higher position with upper cross bar parts 1u under pillar part 2 erected state.
At this moment, Lock Part 22 under the application of force of spring 30, move towards the left side and with the protruding side butt of the upper portion of removing action bars 6, because removing the upper portion of action bars 6 and teat 28 butts of Lock Part 22, even therefore the operating position 6d that will remove action bars 6 under this state towards above pushing, also can't operate releasing action bars 6 fully.
Like this, in this example, removing the closing any opening portion 7 that forms on the tabular mechanism supports parts 5 of the operating position 6d tegmentum of action bars 6 surrounds and is difficult to and be operated between being not intended to, even the situation of operating between occurring in addition being not intended to also can stop by locked parts 22, realize dual fail-safe thus.
In addition, the such recess 19 of this example constitutes when step-like, and the teat 28 of Lock Part 22 can omit, and by being provided with teat 28, recess 19 is not step-like yet in addition, and its left and right sides is the structure of protruding side.
Then, when making the side horizontal bar become that the folding and unfolding state just makes pillar part 2 rotate to descend when upper cross bar parts 1u is descended, at first operation is operated with teat 29, the application of force that as shown in figure 14 Lock Part 22 is overcome spring 30 right in the figure moves.
Then, under this state, with hand to the operating position 6d that in circular opening portion 7, exposes towards above pushing, then remove action bars 6 and rotate around fulcrum 17 clockwise direction in the figure.Along with this rotation, pin 20 moves towards the top, and this pin 20 moves the upper end of recess 27, thus latch 12 in the application of force that overcomes spring 13 under the drive of operating position 15 and towards above mobile.Like this, as shown in figure 15, the top of latch 12 retreats and breaks away from connecting hole 10, and under this state, pillar part 2 rotates shown in the double dot dash line of Figure 15, thereby can utilize parallel linkage to make the parallel decline of upper cross bar parts 1u.
Subsequently, do not operate removing action bars 6, the upper cross bar parts 1u of decline state is risen, relatively rotate towards solid line state clockwise direction at Figure 15 B-C post parts 2 from the state of double dot dash line, then identical with first example, the rake 11 of parts 9 retreats latch 12, then in latch 12 and connecting hole 10 moment corresponding, latch 12 is engaged in the connecting hole 10 under the effect of spring 13, thereby automatically becomes fastening state shown in Figure 13.
Promptly, owing between releasing action bars 6 and latch 12, be provided with play mechanism, play mechanism constitutes by being arranged on the recess 27 on the operating position 15 and being arranged on the pin of removing on the action bars 6 20 in this example, therefore can move under the situation that releasing action bars 6 is not applied external force in latch 12 and its operating position 15, even therefore Lock Part 22 is moved to the action side that locking mechanism is prevented in above-mentioned releasing in the effect of spring 30, can not get back to the state of Figure 13 with having obstacle fully yet.
Like this, in this example,, in addition the locking of Lock Part 22 operating state can be set in when the state that is keeping with erected state descends, security can be improved especially when pillar part 2 need be operated removing action bars 6.
At this, in the above explanation, in the anti-locking mechanism of the releasing of first example, Lock Part is towards direction of action and this two-way structure of operating of non-direction of action with manually, and in the anti-locking mechanism of the releasing of second example, Lock Part is to be subjected to the application of force of spring and to move in direction of action, overcome the application of force of spring and mobile structure in non-direction of action with manual operation, but also can be in contrast, Lock Part in the anti-locking mechanism of the releasing of first example is by spring energized, and cancellation is to the spring of the Lock Part application of force in the anti-locking mechanism of the releasing in second example.
