In addition, the outside of helical spring seat (8) is provided with setting-in and is connected in rotor (11) on its peripheral part.Rotor (11) is flush-mounted on the interior perimembranous of reel (5), is connected with reel (5).This rotor (11) is positioned at the left part of reel (5).
In addition, in the right part of reel (5), also be provided with rotor (12) on the interior perimembranous that is flush-mounted in reel (5).This rotor (12) is irrelevant with fixed axis (3), but is provided with on coaxial with rotor (11), in the axle of right part, can positive and negatively be supported in pivotally on the carriage (2).
Thereby, in the spool screen shown in Fig. 1 (a) and (b), by can positive and negatively being connected in rotor (11) on the helical spring seat (8) and the opposing party's rotor (12) pivotally, under the state that is supported on carriage (1), (2), the reel (5) that is connected on rotor (11), (12) can positive and negatively turn round.When pulling out screen (4), reel (5) just changes, and by the counter-rotating of reel (5), screen (4) is batched in reel (5).
In addition, in the spool screen shown in Fig. 1 (a) and (b), pull out screen (4), make reel (5) when just changeing, the rotor (11) of drive unit (7) together turns round with helical spring seat (8), on the other hand, helical spring seat (9) is fixed on the fixed axis (3), and is supported and do not turned round by axle bush (10), therefore, be accompanied by the just commentaries on classics of reel (5), helical spring (6) reverses.As a result, go up the moment that generation makes reel (5) counter-rotating at drive unit (7).Thereby when discharging this moment, the screen of pulling out (4) automatically batches on the reel (5) owing to the counter-rotating of reel (5).
In addition, in spool screen of the present invention, in reel (5), in keep check mechanism (13), this device when the batching of screen (4) and the counter-rotating of drive unit (7) when together reel (5) being reversed apply brake force.
Fig. 2, Fig. 3 are sectional view, the exploded perspective view of an embodiment of this check mechanism (13).
Example as shown in Figures 2 and 3, check mechanism (13) have with the together rotating check mechanism main body of reel shown in Figure 1 (5) (14), be arranged at its inner and only when reel (5) reverse speedup slew gear (15) of action, can be supported in freely to rotate in gyroscopic output side one end of this speedup slew gear (15), by the centrifugal force that revolution produced of speedup slew gear (15) tend to foreign side centrifugal partition (16), can contact with this centrifugal partition (16) and brake drum (17) by producing brake force with contacting of centrifugal partition (16).The reel brake device (the special flat 1-244394 of hope, spy open No. the 2708240th, flat 3-107089, special permission) that is proposed before the application and provided by the applicant has been provided this check mechanism (13), and it is roughly as described below.
That is,, be provided with guard ring (20) pivotally, on this guard ring (20), be provided with many parallel pins (21), be provided with planetary gear (22) thereon pivotally being arranged on the axle (19) at stator (18) center.In the present embodiment, in guard ring (20), be provided with 3 planetary gears (22), but be not specially limited in this number.
The central gear (23) that is meshed with these planetary gears (22) is arranged on the axle (19) pivotally.In addition, the inner peripheral surface of check mechanism main body (14) is provided with the inner peripheral surface gear (24) that is meshed with planetary gear (22).Check mechanism main body (14) as previously mentioned owing to together turn round with reel (5) shown in Figure 1, the revolution of check mechanism main body (14) makes that the revolution of rotating central gear (23) is faster than the revolution of reel (5) by planetary gear (22).That is the revolution height of the ratio of revolutions reel (5) of central gear (23).
Moreover check mechanism main body (14) is identical with rotor (11), (12) shown in Figure 1, can also easily be realized turning round integratedly with reel (5) by the interior perimembranous that for example is flush-mounted in reel (5) to outstanding setting-in portion (14a) of foreign side.In addition, on the peripheral part of check mechanism main body (14), as shown in Figures 2 and 3, O shape ring (25) can be set, because this O shape ring (25), the load that can prevent to comprise screen (4) after the batching of reel (5) etc. puts on the check mechanism (13), realizes the smooth and easy revolution of speed increasing mechanism (15) by stablizing the axle center.
Moreover, in speed increasing mechanism (15), as shown in Figures 2 and 3, be provided with parallel pin (26) at central gear (23) with planetary gear (22) engaging piece opposite edge-on, and can be provided with planetary gear (27) freely to rotate, in on being engaged in the inner peripheral surface gear (24) of check mechanism main body (14), the central gear (28) that is meshed with this planetary gear (27) can rotatably be arranged on the axle (19).Adding this planetary gear (27) and central gear (28), is effective to the further speedup of the gyroscopic output of speedup slew gear (15).In Fig. 2 and embodiment shown in Figure 3, at opposite edge-on the be provided with pin (29) of central gear (28) with the engaging piece of planetary gear (27), an end of aforementioned pin (29) can support aforementioned centrifugal partition (16) freely to rotate.
Because check mechanism main body (14) is turned round simultaneously with reel (5), the centrifugal partition (16) that is supported by the gyroscopic output side of above speedup slew gear (15) contacts with brake drum (17) owing to the centrifugal force that revolution produced of speedup slew gear (15) tends to foreign side.Owing to this contact, produce the brake force of the turning power of relative reel (5).As previously mentioned, the action of speed increasing mechanism (15) is carried out when only the reel (5) when batching screen (4) reverses, thereby the counter-rotating effect of the relative reel of above-mentioned brake force (5).In order to realize these functions, in spool screen of the present invention, for example shown in Figure 1, stator (18) in one of inscape that also can constitute check mechanism (13), in its left part (18a), be connected with the helical spring seat (9) on the right side of drive unit (7), when axle (19) was fixed on the extended line of fixed axis (3), elastic clutch (30) placed between stator (18) and the guard ring (20).
Elastic clutch (30) can be as shown in Figures 2 and 3 by a volume or multireel spring (31) with in the front end of guard ring (20), constitute with the upright 2 pieces of contact chips (32) that are provided with of predetermined distance.That is, spring (31) loosely is wound on the right part (18b) of stator (18), and its at least one end erects, and this rising portions (31a) inserts between the 2 pieces of contact chips (32) that are arranged on the guard ring (20), and can contact.By this elastic clutch (30), guard ring (20) can not turn round spring (31) to the rolling-in direction, and can only be to the direction revolution of loosening.Thereby, when the turning power with reel (5) the rotating check mechanism main body of one (14) is passed to guard ring (20) by speed increasing mechanism (15), owing in the occasion of its gyratory directions for directive effect that spring (31) is loosened, guard ring (20) also turns round, and speedup slew gear (15) is failure to actuate.This is equivalent to the just commentaries on classics with the reel (5) of screen (4) when pulling out.On the other hand, the turning power of transmitting to guard ring (20) with spring (31) in the occasion of rolling-in directive effect, guard ring (20) does not turn round, thereby, follow the revolution of check mechanism main body (14), brake force by the contact of centrifugal partition (16) and brake drum (17), takes place in speedup slew gear (15) action.The counter-rotating of reel (5) when this is equivalent to batch screen (4).
Like this, in spool screen of the present invention, in order to solve aforesaid technical problem, as shown in Figures 2 and 3, in centrifugal partition (16), the position that contacts with brake drum (17) not, the upright clutch pawl (33) of establishing on the right flank for example particularly, have the clutch main body (35) of ratchet (34) that can engaging-in this pawl (33), be connected with the check mechanism main body (14) of check mechanism (13).
Like this, by on the centrifugal partition (16) that is provided with on the speedup outlet side of the speedup slew gear (15) of check mechanism (13), clutch pawl (33) uprightly is set, with respect to the situation that only can stop in each week in the present clutch at 2 to 4 places, at least can stop on many one times positions, the screen stop position in the time of screen (4) can being pulled out and batched is compared with the past to be set more accurately.Can more want the position that opens or closes, or just in time screen (4) stopped in this position near the user.Become good operability, spool screen easy to use.And, when the engaging-in ratchet of clutch pawl (33) (34) is middle, because ratchet (33) is set in place on the centrifugal partition (16) of the speedup outlet side of speed increasing mechanism (15), the power that is added on the both sides is 1/ speedup multiple, alleviated burden, prolonged the life-span of clutch effectively clutch.
In addition, in spool screen of the present invention,, the limiter (36) that is adopted in the check mechanism (the special flat 1-244394 of hope, spy open No. the 2708240th, flat 3-107089, special permission) of aforesaid spool screen can be set as Fig. 1～shown in Figure 3.This limiter (36) is called the revolution shut-down mechanism in above-mentioned check mechanism, it is roughly, has the steel ring (39) that is arranged at guide (38) guiding of the interior perimembranous of limiter main body (37) by outstanding, this steel ring (39) can be gone up revolution at aforesaid axle (19), has cut screw thread (40) on the interior week of local periphery of axle (19) and steel ring (39).
This limiter (36) in spool screen of the present invention, can be connected with the right-hand member of clutch main body (35).That is, limiter main body (37) can be connected with clutch main body (35).Because clutch main body (35) is connected with brake main body (13), the limiter main body (37) that is connected with clutch main body (35) is together turned round with reel (5).Revolution by this limiter main body (37), steel ring (39) by guide (38) guiding also turns round, but because the local peripheral part of its interior perimembranous and axle (19) has been cut screw thread (40), steel ring (39) moves along guide (38), corresponding to the counter-rotating of reel (5), very fast right part with clutch main body (35) or central gear (28) contacts.By this contact, the revolution of check mechanism main body (14) is stopped.That is stop reliably when, spool screen is in screen (4) fully batches into reel (5).Screen (4) is being pulled out from reel (5), when just changeing, returning to the position at initial stage corresponding to its rotating degree, steel ring 39, final, that is, return to the primary position of screen (4) when pulling out fully.
In addition, in spool screen of the present invention, shown in Fig. 1 (a), carriage (1), (2) have bracket main body (1a), (2a), and be formed with the outstanding axial region of left end, the right-hand member that can insert respectively, the bearing portion the axial region of left part, rotor (12) right part of fixed axis (3), the portion of bearing (1b), (2b) that can turn round and be provided with regularly with respect to bracket main body (1a), (2a) as the aforementioned from reel (5), can be with respect to carriage, the direction of insertion of regulating reel (5).
