Taking the lead pin 4 is not fixed on any one in tabular component 3,3, inner plate 12,12 and roller 14.Therefore,, to take the lead centered by the foot 42 of pin 4, tabular component 3,3 and the inner plate 12,12 of the left and right sides can carry out relative rotary motion.
In addition, take the lead the head 41 of pin 4 to lock at the periphery of the through hole 31 of the outside of tabular component 3, in the front end cotter pin 52 of foot 42, be inserted through through hole 43.Therefore, can prevent from taking the lead pin 4 stretches out from through hole 31 and through hole 121 etc.
Fig. 4 and Fig. 5 are the schematic diagram for the erection sequence of 2 pairs of chain bodies 1 of coupling piece is described.
First, on one side with reference to Fig. 4, on one side to by tabular component 3 with take the lead the situation that pin 4 processes respectively and describe.
Another end about chain body 1, operator are at the outside arranged opposite tabular component 3,3 of one group of inner plate 12,12 of downside, between this inner plate 12,12, configure the roller 14 of downside, the position of through hole 121,121, through hole 31,31 and through hole 141 is aimed at.
Then, operator make downside take the lead pin 4 be inserted through in the following order left side tabular component 3 the through hole 31 of downside, the through hole 121 of inner plate 12 in the middle left side of one group of inner plate 12,12 of downside, the through hole 121 of inner plate 12 on the middle right side of one group of inner plate 12,12 of the through hole 141 of the roller 14 of downside, downside, the through hole 31 of the downside of the tabular component 3 on right side.
The pin 4 of taking the lead of downside has played in present embodiment 2nd effect of taking the lead pin.
Then, operator between tabular component 3,3 arranged opposite as one group of inner plate 12,12 of the upside of an end of chain body 1, between this inner plate 12,12, configure the roller 14 of upside, the position of through hole 121,121, through hole 31,31 and through hole 141 is aimed at.
And, operator make upside take the lead pin 4 be inserted through in the following order left side tabular component 3 the through hole 31 of upside, the through hole 121 of inner plate 12 in the middle left side of one group of inner plate 12,12 of upside, the through hole 121 of inner plate 12 on the middle right side of one group of inner plate 12,12 of the through hole 141 of the roller 14 of upside, upside, the through hole 31 of the upside of the tabular component 3 on right side.
The pin 4 of taking the lead of upside has played in present embodiment 1st effect of taking the lead pin.
Then,, about taking the lead pin 4,4, reference mark of operator 44 one sides make cotter pin 52 be inserted through through hole 43,43.
Finally, operator carry out opening to the front end of cotter pin 52.Consequently, across through hole 43,43 construction opening pins 52.
As mentioned above, in operation to tabular component 3,3 with take the lead pin 4,4 and process respectively.Single tabular component 3 and single any one of taking the lead in pin 4, be fixed and compare pin at tabular component like that with the draw-barring that possesses coupling piece in the past, in narrow and small place, processes and become easy especially.Therefore,, even if workshop is narrow and small, also can improve the operability that coupling piece 2 is installed on to the operation of chain body 1.
However, the erection sequence of 2 pairs of chain bodies 1 of coupling piece is not limited to the order shown in Fig. 4.
Here, on one side with reference to Fig. 5, on one side to by tabular component 3 with take the lead the situation that pin 4 processes in advance integratedly and describe.
About another end of chain body 1, operator configure the roller 14 of downside between one group of inner plate 12,12 of downside, and the position of through hole 121,121 and through hole 141 is aimed at.
In addition, about an end of chain body 1, operator configure the roller 14 of upside between one group of inner plate 12,12 of upside, and the position of through hole 121,121 and through hole 141 is aimed at.
And operator are at one group of inner plate 12,12 of above-below direction arranged opposite upside and one group of inner plate 12,12 of downside, right-hand at the inner plate 12,12 on 2 right sides, the tabular component 3 on arranged opposite right side.Now, at upside and downside, respectively the position of through hole 31, through hole 121,121 and through hole 141 is aimed at.
And in addition, operator are by inserting each through hole 31 of the tabular component 3 in left side by taking the lead the foot 42 of pin 4, make the tabular component 3 in left side and take the lead pin 4,4 integrated.Now, each head 41 of taking the lead pin 4 locks at the periphery of through hole 31.So, can suppress to take the lead pin 4,4 to come off from operator's hand.
Then, operator make upper and lower 2 to take the lead pin 4,4 and be inserted through in the following order the through hole 31,31 on the tabular component 3,3 on 121,121 and 2 right sides of through hole on the inner plate 12,12 on 141,141,2 right sides of through hole of the through hole 121,121 on the inner plate 12,12 in 2 left sides, upper and lower 2 rollers 14,14.
Then, about upper and lower both sides take the lead pin 4,4, reference mark of operator 44 one sides make cotter pin 52 be inserted through through hole 43,43.
Finally, operator carry out opening to the front end of cotter pin 52.Consequently, across through hole 43,43 construction opening pins 52.
This erection sequence is similar with 1 the order that coupling piece is in the past installed on to chain body.Therefore the operator that, are familiar with the coupling piece to be in the past installed on 1 order of chain body can easily operate.
As mentioned above, coupling piece 2 is compared with coupling piece in the past, higher for the installation degrees of freedom of chain body 1.The space that is workshop is very abundant, no matter adopt erection sequence as shown in Figure 4 or adopt erection sequence as shown in Figure 5, can the special problem of nothing coupling piece 2 be installed on to chain body 1.
In addition, coupling piece 2, by adopting 1 cotter pin 52 and having sign 44, has improved the operability of the fitting operation of locking body.
But, to compare fatigue strength lower for coupling piece 2 and coupling piece in the past.Yet, have the tensile strength of same degree.So, although in the tensile strength of having relatively high expectations even the lower chain 6 that does not also have special problem of fatigue strength possesses coupling piece 2 is gratifying.
In addition, chain 6 can be also, with coupling piece 2,2 chain bodies 1 are connected to 1 chain body.In this case, the inner plate 12,12 that the inner plate 12,12 end of a chain body 1 being had and an end of another chain body 1 have is connected via coupling piece 2.
In addition, the such clamp that also can record with patent documentation 1 replaces cotter pin 52 to be used as locking body.But worry cannot be continued to use as forming and takes the lead the locking body of the chain different from chain 6 such as the span of pin 4,4 or external diameter.On the other hand, cotter pin 52 can be continued to use as forming and taken the lead the locking body of the chain different from chain 6 such as the span of pin 4,4 or external diameter.That is, cotter pin 52 is as locking body, the number that can seek to cut down components and parts.
And, also can replace 1 cotter pin 52 as locking body 2 difference ratio open pin 52 short cotter pins.In this case, at 2,2 cotter pins 52 are installed one to one on taking the lead pin 4,4.
At this, tell with respect to 2 cotter pins, use the usefulness of 1 cotter pin 52.First, reduced the number of components and parts.And because the through hole 43,43 of taking the lead pin 4,4 across 2 is installed 1 cotter pin 52, so cotter pin 52 inserts through holes 43,43, can suppress each and take the lead unnecessary the rotatablely moving of pin 4.Consequently, the operation of cotter pin 52 being carried out to opening is easy to carry out.
On the other hand, in the situation that 2 independent construction opening pins of through hole 43,43 of taking the lead pin 4,4, even if through hole 43 is inserted in cotter pin, each is taken the lead pin 4 and also can freely rotatablely move.This is because taking the lead pin 4 be not both fixed on tabular component 3,3 and is not fixed on inner plate 12,12 yet.Consequently, the operation of each cotter pin being carried out to the opening trouble that becomes.

Rectangular shaped when raising platform 72 is overlooked.The parking space that has vehicle M in the upper central portion of raising platform 72.Periphery on raising platform 72, all around direction separatedly outstanding 4 joints 76,76 that one is set ...
Joint 76 has the plate-like portion 761,761 of 2 piece a group suitable with one group of inner plate 12,12 of downside.More specifically, half of the long side direction of each plate-like portion 761 and inner plate 12 is suitable.At left and right directions arranged opposite plate-like portion 761,761.At plate-like portion 761, be provided with the through hole 762 suitable with the through hole 121 of inner plate 12.
Erect and be provided with each root pillar 73 corresponding with four jiaos of raising platform 72 on the ground.Beam 74 is set up on a pair of top across adjacent pillar 73,73. Pillar 73,73 ... and beam 74,74 ... form the vehicle frame of sky parking 7.
The rotating shaft of each sprocket wheel 75 is supported by the vehicle frame of sky parking 7 via not shown supporting portion.
Each chain body is configured along the framework of sky parking.An end of each chain body 1 is connected with the joint 76 of raising platform 72 via coupling piece.
Being connected of end of chain body 1 and the joint 76 of raising platform 72 is similar with being connected of an end of chain body 1 in mode of execution 1 and another end.
The central part of the long side direction of each chain body 1 is wound with 1 sprocket wheel 75 or 2 sprocket wheels 75,75.The vehicle frame of sky parking 7 is fixed in another end of each chain body 1 via not shown fixed component.
The not shown motor that solid parking place possesses carries out work, sprocket wheel 75,75 ... be rotated.Now, chain body 1,1 ... reel and shorten, or pull out and elongated.Be accompanied by chain body 1,1 ... coiling/pull out, be suspended to chain body 1,1 ... raising platform 72 carry out rise/fall.
In sky parking 7 as above, each chain body 1 suspention has raising platform 72, with lower speed, plays.Therefore,, although chain body 1 needs higher tensile strength, do not need higher fatigue strength.So, although do not have special problem via there being higher tensile strength not have the coupling piece 2 of higher fatigue strength that chain body 1 is connected in to raising platform 72 yet.
Suppose via tensile strength and fatigue strength all very high existing coupling piece chain body 1 is connected in to raising platform 72, worry to produce the increase of the superfluous caused unnecessary manufacture cost of performance of coupling piece.
As previously mentioned, the effect of suspension device in mode of execution of the present utility model has been played by sky parking 7.In addition, raising platform 72 has played the effect of the article holding part that vehicle M is put of the mode keeping as article.
In addition, be not limited to the structure that sky parking 7 possesses coupling piece 2.For example, can be also the structure that fork truck possesses coupling piece 2.In this case, forked lifting unit is connected via coupling piece 2 with chain body.Now, fork truck and forked lifting unit have played the effect of suspension device and article holding part in mode of execution of the present utility model.
Article holding part in mode of execution of the present utility model is not limited to the raising platform 72 that vehicle M is put or the forked lifting unit that inserts tray, for example, can be also the suspension hook that hangs with article.
In addition, the suspension device in mode of execution of the present utility model can be also that article holding part does not move the structure of (for example lifting).
Anyway, although wish coupling piece 2 to be installed on the chain body 1(chain body 1 for suspending in midair for example that needs higher tensile strength not need higher fatigue strength most).
It is all example and be not to limit that this disclosed mode of execution should be thought of as.It not is that above-mentioned implication still has impartial implication and all changes within the scope of claim with claim scope that scope of the present utility model is intended to comprise.
In addition, as long as can reach effect of the present utility model, in coupling piece 2, chain 6, sky parking 7, also can be included in the structural element of not recording in mode of execution 1,2.
The disclosed structure important document of each mode of execution (technical characteristics) can combine mutually, by combination, can form new technical characteristics.
