Calmodulin binding domain CaM 10 can be formed by the block that is fixed to shank 2 at least in part, as among the embodiment shown in Fig. 1 to 12.In this embodiment, the top of calmodulin binding domain CaM 10 is formed directly in the shank 2, and the remainder of calmodulin binding domain CaM 10 is formed in the block that is rigidly fixed to shank 2 as the continuous part with top.

Perhaps, calmodulin binding domain CaM 10 can be integrally formed with shank 2, as shown in Figure 13 according in the constructional variant of pin of the present invention.

In this constructional variant, pin with Fig. 1 to 12 in the elements relative the described element of answering indicate with identical Reference numeral.

Different from the embodiment shown in Fig. 1 to 12 is, in the embodiment shown in fig. 13, in the groove 19 that the upper end 12a of the part 8a of

thin slice

6a, 6b, 8b, 12b are slidably inserted into open front, this groove be arranged near the base portion place of calmodulin binding domain CaM 10 to lower area.

In this constructional variant, since side 10a, the 10b of calmodulin binding domain CaM with respect to set among the embodiment shown in Fig. 1 to 12, further retract towards the rear side of shank 2, so first paragraph 13a, the 13b of the part 8a of

thin slice

6a, 6b, 8b have rear protrusion 22a, 22b, thereby allow to vertically move with respect to adjacent needles and make described

first paragraph

13a, 13b under any circumstance all cooperate side 10a, the 10b of the calmodulin binding domain CaM 10 of the adjacent needles that similar pin 1 provides along with pin 1.

In the second constructional variant, shown in Figure 15 and 16, calmodulin binding domain CaM 10 is not provided with inclined side, and this is because shank 2 has the side that is parallel to each other at described calmodulin binding domain CaM 10 places.In this second constructional variant, calmodulin binding domain CaM 10 is only formed by front surface 10c, this front surface tilts with respect to the longitudinal axis of shank 2, thereby forwardly will be combined by the part 8a of

thin slice

6a, 6b, the section of the zone that 8b occupies and the shank 2 that is arranged on the top.And upper end 12a, the 12b of the part 8a of

thin slice

6a, 6b, 8b is slidably inserted in recess 19a, the 19b in the both sides that are formed at shank 2, and its mode is similar to the embodiment of Fig. 1 to 12.

In this second constructional variant, pin with Fig. 1 to 12 in the elements relative described other element of answering indicate with identical Reference numeral.

In the third and fourth embodiment according to pin of the present invention, shown in Figure 17 to 20, as arranging in the second constructional variant shown in Figure 15 and 16, difference is pin basically, two

thin slice

6a, 6b form, rather than form two unitary part.

In the 3rd constructional variant,

thin slice

6a, 6b obtain by the single part 23 that blank shown in Figure 180 forms, and along the line 24 is folded.Blank part 23 is further crooked so that

first paragraph

13a, 13b and the

3rd section

15a, 15b to be provided.

In the 4th constructional variant,

thin slice

6a, 6b obtain by the single part 25 that blank shown in Figure 20 forms, and along the line 26 is folding.Blank part 25 is further crooked so that

first paragraph

13a, 13b and the

3rd section

15a, 15b to be provided.

In the constructional variant shown in Figure 17 to 20, because two

thin slice

6a, 6b are integrally formed, so there is single lower area 20a to be used for thin slice is fixed to shank 2 integratedly.

In the constructional variant shown in Figure 17 to 20, pin with earlier figures in the elements relative described other element of answering indicate with identical Reference numeral

In the embodiment shown in all, shank 2 have the fore edge at part 8a, the 8b of

thin slice

6a, 6b above the calmodulin binding domain CaM 10 and the part between the head 3, this fore edge reduce shank 2 before take up space, thereby avoid in knitted loop 9 transfer processes

rear protrusion

18a, 18b interference with part 8a, the 8b of thin slice 6a, the 6b of adjacent needles.

By being equipped with pin of the present invention for hosiery knitting machines and by activating as described below these pins, knitting technology weave or knitted loop 9 directly can be transferred to respect to pin 1 from a pin 1 and be arranged on side direction either side and

adjacent pin

1a or 1b, and the add ons that need not to pick up knitting technology weave or knitted loop 9.

For simplify and more clear for the purpose of, always describe referring to figs. 1 through the embodiment of the pin shown in 12 knitting technology weave or knitted loop 9 are transferred to the used method of adjacent needles from a pin, and do not change the following fact: for total aspect, this is described also applicable to the constructional variant of pin shown in the drawings thereafter.Also will clearly with reference to some structure embodiment of pin, the concrete aspect according to the use of pin of the present invention be described.

For the purpose of more clear, the pin adjacent with the pin 1 that must discharge knitting technology weave or knitted loop 9 indicates with Reference numeral 1a, 1b, still can provide as aforementioned pin 1.

The given description that knitted loop 9 is transferred to adjacent needles 1b from pin 1, for the purpose of more clear, with reference to round hosiery knitting machines, the pin of supposing to shift betwixt knitted loop 9 is arranged in the syringe 40 of the formation needle holder of knitting machine, then do not change the following fact: can be used in the circular disc knitting machine with syringe and dials according to pin of the present invention yet, perhaps more generally be used in the straight line and circular knitting machine of single or double bed.

In the following description, with reference to Fig. 5 to 9, the pin 1 of supposing to be arranged between pin 1b, the 1a is to carry knitted loop 9 and it must be released into the pin of adjacent needles 1b, and is arranged on the impact that another pin 1a on the opposition side of pin 1b is not shifted by knitted loop 9 with respect to pin 1.Pin 1 is also referred to as " release pin " hereinafter, and pin 1b is also referred to as " accepting pin ", and pin 1a is also referred to as " not working needle ".

For knitted loop 9 is transferred to adjacent needles 1b from a pin 1, after forming knitted loop 9 and after the knitted loop to previous formation carries out knocking over, come lift pins 1 by the pin actuating cam that cooperates heel 5, thereby above knitting formation plane 21, give prominence to one section, this knitting formation plane as everyone knows as shown in the figure by sinker (for simplicity, not shown in Fig. 5 to 9) form the knitted loop 9 that the sinker maintenance has just formed.The pin 1 that must discharge knitted loop 9 rises to a certain degree and takes 21 places, knitting formation plane to part 8a, 8b with thin slice 6a, 6b, and part 8a, 8b extracted out fully from the zone that is occupied by so-called " band ", strip side is to the seat section that the restriction pin slides therein, and seat section is made of the axial groove of syringe 40 sides.Like this, at first move apart shank 2 by elastic reactance with its part 8a, 8b owing to the existence of band is pressed against the thin slice 6a, the 6b that discharge on the pin 1, therefore be transferred to the operating position.Along with the lifting that discharges pin 1, the shank 2 of pin 1 upwards slides in knitted loop 9 shelves shoulder 17a, 17b, this knitted loop 9 at first combined regional 10 passes, and then passed by the part 8a of thin slice 6a, 6b, 8b, thereby this knitted loop 9 is widened gradually and is suitable for being accepted at least pin 1b and passes.In this step, the gradually expansion of knitted loop 9 is guaranteed in the existence of calmodulin binding domain CaM 10, thereby avoids the excessive stresses of knitted loop and thin slice 6a, 6b.

At this moment, knitted loop 9 will be transferred to accepts pin 1b and moves up with respect to discharging pin 1, thereby its unlimited head 3 is inserted in the space that comprises between the part 8b that discharges pins 1 and the shank 2.Should be able to notice, accept between pin 1b is arranged on its head the rear protrusion 18b that discharges pin 1 and shank 2 when it promotes the side 7b.Because this fact, the knitted loop 9 of accepting on the side 7b that part 8b that pin 1b prevents thin slice 6b is resisted against the shank 2 that discharges pin 1 is crushed fully, bearing before first paragraph 13b limits, should prevent that the needle latch 4 of accepting pin 1b from rotating around axis 4a by front bearing, guarantee that the needle latch 4 of accepting pin 1b opens, specifically as shown in Figure 7.Working needle 1a is not in lower position with respect to accepting the occupied position of pin 1b, but its head 3 preferably under any circumstance all is arranged between the side 7a of rear protrusion 18a and shank 2, therefore by rear protrusion 18a " covering ", thereby the transfer process of not interfering knitted loop 9, specifically as shown in Figure 8.

Then, finished the lifting of accepting pin 1b until its head 3 be positioned at above the knitting formation plane 21 and therefore be positioned at the knitted loop 9 that will cooperate above after, discharge pin 1 and descend and accept pin 1b and preferably rise to the position corresponding with the knitting technology weave holding position.

The decline that discharges pin 1 can make to be accepted pin 1b and moves, and projects upwards with the part 8b of its head from thin slice 6b thereby accept pin 1b.And the decline of pin 1 causes that the knitted loop 9 that arranges around

thin slice

6a, 6b slides along the 3rd section 15b of part 8b, makes knitted loop 9 shift to shank 2, and takes knitted loop 9 to accept pin 1b head.

Should be able to notice, because the upper end of thin slice 6b is shelved in the zone that is positioned at head 3 fronts and is resisted against on the shank 2 that discharges pin 1, so accepting the head 3 of pin 1b in fact projects upwards from the part 8b of thin slice 6b, and can not interfere the part 8b of the thin slice 6b that discharges pin 1, therefore need not its upper end will be separated with the shank 2 that discharges pin 1.Like this, can significantly reduce the head 3 of accepting pin 1b and the wearing and tearing that discharge the thin slice 6b of pin 1.

When discharging pin 1 and move past the knitted loop 9 that is arranged in the head 3 of accepting pin 1b and cause that the head 3 that discharges pin 1 is closed by needle latch 4 with its needle latch 4 in decline, two

pins

1 and 1b can drop to 21 belows, knitting formation plane together.In this decline process, the part 8a of

thin slice

6a, 6b, 8b are by cooperating band to move to the non-operative position.

This function of band can be with reference to the second constructional variant of pin 1 shown in Figure 15,16, wherein, band indicates with Reference numeral 27, the seat section or the groove that are limited by band 27 side direction indicate with Reference numeral 28, and syringe (more generally being needle holder) indicates with Reference numeral 40.

Should be able to notice, the existence of shelving

shoulder

17a, 17b allows knitted loop 9 is transferred to 21 tops, knitting formation plane just, this is because described supporting

shoulder

17a, 17b by the correct location of the knitted loop 9 himself realizing being transferred, avoid it to descend along the shank 2 that discharges pin 1.

In this case, after knitted loop 9 shifts, part 8a, the 8b transfer from the operating position to the non-operative position of

thin slice

6a, 6b can descend between

adjacent needles

1a, 1b and realize along with discharging pin 1, this is because first paragraph 13a, the 13b of part 8a, the 8b of

thin slice

6a, 6b cooperates side 10a, the 10b of calmodulin binding domain CaM 10, as shown in FIG. 10 and 11.

Working needle 1a does not participate in the transfer of knitted loop 9, this elastic deformation level when the working needle 1a part 8a that can be used to reduce the thin slice 6a of adjacent release pin 1 does not leave the corresponding side surface 7a that discharges pin 1, thus the stress that the knitted loop 9 that is transferred and another thin slice 6b stand reduced.This can realize by the part that is positioned at 21 direct belows, knitting formation plane of restriction forward extension or elimination band 21, thereby the thin slice 6a of each pin, the part 8a of 6b, 8b can move to the operating position just by elastic reactance, and can upwards not extract out with respect to knitting formation plane 21, and by setting in advance calmodulin binding domain CaM 10 at the part 8a place of the thin slice 6a of adjacent release pin 1 for pin 1a, can be owing to limiting cooperating of the part 8a of the calmodulin binding domain CaM 10 of working needle 1a not and the thin slice 6a that discharges pin 1 or preventing that the part 8a of thin slice 6a is bent away from the side 7a of shank 2.Then, discharge pin 1 and not working needle 1a rise together, thereby discharge pin 1 in knitted loop 9 interior slips, move and abut to the shelving on the shoulder 17b of thin slice 6b until discharge pin 1, its part 8b is in the operating position, and with the part 8a that contacts continuation restriction thin slice 6a of the calmodulin binding domain CaM 10 of working needle 1a and the side 7a of release pin 1 do not separate.This use not possibility of working needle 1a is shown among Figure 12, and its three pins 1,1a, 1b that shows is in groups activated successively along the direction shown in the arrow 30.In described figure, for simplicity, all pins are shown as corresponding needle latch 4 is opened, and can not change the following fact: needle latch 4 can open or close at the head of pin 3 according to the condition of work of pin.

This use of working needle also can not have the above-mentioned various constructional variant of pin 1.

In order to resist the elastic bending of

part

8a, 8b, widening in the process of knitted loop 9, except rear protrusion 18b being shelved be resisted against on the head 3 of accepting pin 1b, also can use other element of knitting machine, such as sinker 29 and/or band 27.

In practice, as shown in figure 14, by sinker 29 along syringe 40 move (can obtain in a manner known way) radially, and by the lifter motion that discharges pin 1, after part 8a, the 8b of

thin slice

6a, 6b arrive the operating position, in the space that comprises between side 7a, the 7b that can cause sinker 29 to insert to discharge pins 1 and part 8a, the 8b of

thin slice

6a, 6b, this sinker be arranged on the side that discharges pin 1b and be arranged on working needle 1a not with release pin 1 opposition side on.

Equally, can be with the drape forming of the close sinker 29 of band 21: after part 8a, the 8b of

thin slice

6a, 6b move to the operating position by elastic reactance, promote and discharge after the pin 1, make being arranged on of two bands 27 accept on the side of pin 1b and be arranged on working needle not 1a's and discharge on pin 1 opposition side shown in zone location in the space that comprises between part 8a, the 8b of the side 7a, the 7b that discharge pin 1 and

thin slice

6a, 6b.

In both cases, rear protrusion 18a, the 18b of

second portion

14a, 14b that sinker 29 and/or band 27 cooperates part 8a, the 8b of

thin slice

6a, 6b guarantees to prevent

part

8a, 8b because the shank 2 of release pin 1 is pressed in the effect of knitted loop 9.

Be not transferred to the adjacent needles that is located at the left side among the figure in order knitted loop 9 not to be transferred to the adjacent needles 1b that is located at pin 1 the right, accept the described actuating of pin 1b as above reference and be arranged on the described pin on the left side with regard to it is enough.

Certainly, if pin according to the present invention be used in the disc type knitting machine with syringe and dials, then pin radially outward mobile the replacement rise, radially move inward to replace to descend.

Based on the given above-mentioned explanation of reference single needle bed circular knitting machine, the knitting machine that under any circumstance all can be mounted to reference to pin according to the present invention and directly draw the motion of giving pin and change.

Concrete structure according to pin of the present invention allows to provide the thickness that reduces to pin according to the present invention, thereby allows in its knitting machine that is used in high accuracy (more than per inch 18 pins).

Should be able to notice, can be advantageously utilised on the double needle bed machine according to pin of the present invention, thereby knitting technology weave is transferred on another needle-bar from a needle-bar, also has the adjacent needles that knitting technology weave is transferred to same needle-bar from a pin of a needle-bar, and need not relative motion between the needle-bar, accuracy and the complexity problem of therefore avoiding these motions to bring.

And, use can be shifted the knitting technology weave of the either side of the pin that the available alternating movement from knitting machine activates according to pin of the present invention, the knitting areas of the knitwear that permission produces has any shape that increases or reduce knitting technology weave, thereby improves its quality and fineness.

It has been found in practice that, realized the aim of expection fully according to pin of the present invention, but this is because the slip between the head of the adjacent needles that the elastic bending part by the restriction thin slice and knitting technology weave or knitted loop will be transferred to, reduce the wearing and tearing of these parts, thereby realized the long-term reliability of pin.

And, in the transfer process of knitting technology weave or knitted loop, but being released the elastic bending of the thin slice of pin, the head of adjacent needles partly covers, guarantee high accuracy and reliability in the transfer operation of knitting technology weave or knitted loop.

Another advantage according to pin of the present invention is: but can prevent the elastic bending part of thin slice because the knitting technology weave that is transferred or the effect of knitted loop are pressed against on the shank of pin, and/or other element of the knitting machine that is mounted to by adjacent needles or by pin, but the elastic bending part that prevents or limit thin slice separates with the shank that must discharge knitting technology weave or knitted loop pin, thereby the height versatility when realizing actuating and use.

Therefore the pin of imagination can stand multiple modification and modification, and all these is within the scope of appended claims; All details can further be replaced with other technical equivalent element.

In fact, employed material and size can be as requested with the prior art state and for arbitrarily.

The application requires the priority of disclosures in Italian patent application MI2008A000121 number, this with referring to mode introduce its content.

When the drawings attached mark is followed in pointed technical characterictic back in claims, comprise that these Reference numerals only are in order to increase the intelligibility of these claims, and therefore these Reference numerals to the explanation of each member of being determined by way of example by these Reference numerals without any restriction.
