In the drawings, 1 be illustrated in the car that disposes with the mode of going up and down freely in the hoistway of elevator.
At this car 1 plate 2 is installed.This plate 2 is roughly L word shape when overlooking observation, this plate 2 is fixed to and makes the face that contacts with the one arm of this L word perpendicular to paper.
On near the terminal up floor the well enclosure 3, according to order from top to bottom, outstanding in the horizontal direction the 1st arm 4a, the 2nd arm 4b, the 3rd arm 4c, the 4th arm 4d and the 5th arm 4e of being provided with.These arms all have equal lengths.
And, the 1st position detector 5a vertically is installed, the 2nd position detector 5b vertically is installed, the 3rd position detector 5c vertically is installed, the 4th position detector 5b vertically is installed, the 5th position detector 5e vertically is installed at the 5th arm 4e and paper at the 4th arm 4d and paper at the 3rd arm 4c and paper at the 2nd arm 4b and paper at the 1st arm 4a and paper.
These position detectors are roughly " コ " shape when overlooking observation.And these position detectors dispose along the track that plate 2 passes through when car 1 goes up and down, and are used to stipulate that along the position in a plurality of stages of the up-down direction setting of car 1 be operating point.
That is, at this near position detector of being located at the upper extremity floor is described, therefore, the 1st position detector 5a that is installed in the 1st arm 4a stipulates upper the 1st operating point.And the 2nd position detector 5b regulation that is installed in the 2nd arm 4b is positioned at upper the 2nd operating point at the preset distance place of upper the 1st operating point top.
Equally; To separate the mode of predetermined space respectively; The 3rd position detector 5c that is installed on the 3rd arm 4c stipulates upper the 3rd operating point, and the 4th position detector 5d that is installed on the 4th arm 4d stipulates upper the 4th operating point, and the 5th position detector 5e that is installed on the 5th arm 4e stipulates upper the 5th operating point.
Therefore, each operating point utilizes a position detector to stipulate and can distinguish each other respectively like this, in other words, is provided with the quantity position detector identical with the quantity of operating point.
In addition, below near the terminal floor hoistway side be provided with the next position detector.This next position detector is except its fixed position difference, and other upper position detector with above-mentioned explanation is identical, thereby omits its detailed description.
The 1st position detector 5a, the 2nd position detector 5b, the 3rd position detector 5c, the 4th position detector 5d, the 5th position detector 5e are in operating state usually.And when the plate 2 of car 1 moves about in the depressed part that is inserted into " コ " shape, when engaging with the noncontact mode, will cut off magnetic, position detector becomes non-action state, and output signal.
In the device for detection of position of car body that constitutes like this, when car 1 rise and from middle floor near the upper extremity floor and when the plate 2 of car 1 arrives upper the 1st operating point, the 1st position detector 5a is cut off magnetic and is in non-action state by plate 2.This moment, the signal of output was transfused to not shown control setup, arrived upper the 1st operating point thereby detect car 1.

These the 3rd position detectors 5c, the 4th position detector 5d and the 5th position detector 5e are that low speed is used position detector when advancing, and the locus configurations of passing through when car 1 goes up and down with plate 2b when low speed is advanced.
At this, when observing with plate 2b when low speed is advanced, be installed in well enclosure 3 sides with plate 2a during high-speed travel, thereby the track that the track that passes through when car 1 goes up and down with plate 2a during high-speed travel passes through with plate 2b when comparing low speed and advancing is near well enclosure 3 sides.
Therefore; Owing to be disposed at when advancing with cooresponding the 3rd position detector 5c of plate 2b, the 4th position detector 5d and the 5th position detector 5e with cooresponding the 1st position detector 5a of plate 2a and the 2nd position detector 5b during with high-speed travel, thereby the length of the 1st arm 4a and the 2nd arm 4b is lacked than the length of the 3rd arm 4c, the 4th arm 4d and the 5th arm 4e with low speed.
In addition, other structure is identical with aforesaid embodiment 1, thereby omits its detailed description.
In the device for detection of position of car body that constitutes like this, at car 1 when the hoistway centre portion goes up and down at a high speed, the 1st position detector 5a or the 2nd position detector 5b during by high-speed travel with plate 2a cut-out magnetic and be in non-action state.This moment, the signal of output was transfused to control setup, arrived the 1st position detector 5a or the 2nd position detector 5b specified action point thereby detect car 1.
And, during near the upper extremity floor, cut off magnetic and be in non-action state with plate 2b when the 3rd position detector 5c, the 4th position detector 5d or the 5th position detector 5e are advanced by low speed at car 1 low speed.This moment, the signal of output was transfused to control setup, arrived the 3rd position detector 5c, the 4th position detector 5d or the 5th position detector 5e specified action point thereby detect car 1.In addition, below terminal floor also identical.
In the device for detection of position of car body that constitutes as stated, with 1 the same can the area that position detector and plate occupy in the horizontal section of hoistway inhibition of embodiment be less degree, and raising layout performance.
And; In addition; When low speed being set advancing with plate with use plate when the size of up-down direction is advanced with low speed during with the different high-speed travel of plate; And use position detector during the high-speed travel of the locus configurations of passing through when car goes up and down with plate during with position detector with along high-speed travel when the low speed that the locus configurations of passing through when car goes up and down with plate when low speed is advanced is set is advanced; Can consider thus according to the position in the hoistway especially because of being near the rising or falling speed of cars different with centre portion terminal; Improve the reliability of the plate detection of a position detector, and can prevent in plural position adjacent detector, to detect simultaneously the generation of the error detection of plate.
