Description
Technical field
The application's request spy of on January 8th, 2010 in Japanese publication is willing to the priority of 2010-003396.By quoting its full content in this application in this statement.
It mainly is the lead-in wire (stay cord) that twines on spool when being used for the pet dog stroll that the present invention relates generally to a kind of, and can derive the portable spool lead-in wire (stay cord wind) of Len req lead-in wire
Background technology
The portable spool lead-in wire of known stroll usefulness is constituted as: be wrapped in lead-in wire on the spool no matter the traction force of dog and deriving, and according to circumstances will go between and fix with certain-length, lax lead-in wire can be by automatically twining to the active force that twines the side rotation.
As shown in figure 10, for example the real disclosed spool lead-in wire 9 of flat 3-23166 communique of opening of Japan is constituted as: take in main body cover 91 and be useful on the spool 92 that twines lead-in wire, lead-in wire can be pulled out from the export mouth 93 that is formed on the main body cover 91.Roughly opposition side at the export mouth 93 of main body cover 91 is provided with up knob 94.And the position setting operation portion 95 that thumb catches on when holding handle 94 is by being pressed into locking and the release that this operating portion 95 can go between derives with thumb.
Disclosed spool lead-in wires such as Japanese kokai publication hei 10-59630 communique, registration utility model No. 3114872 communique, though on the thickness of handle and angle, there are some differences, all possess and above-mentioned same formation.And this also is the formation that general in the past spool goes between.
Above-mentioned spool lead-in wire in the past is will four fingers to insert between main body covers and the handle to hold handle as handbag, at export mouth during towards direction of advance, the operating position in than the upper surface of main body cover near the rear portion.And by the operation that the forwards oblique below of this operating portion is pressed into thumb, locking is then removed in the derivation that comes the locking lead-in wire when being pressed into once more.That is, in above-mentioned spool lead-in wire in the past, when the derivation of wanting to stop to go between, need be to the roughly the same direction push operation portion of direction of deriving with lead-in wire.
Yet operation as described above, the action meeting of deriving as being used to stop to go between is at some nature a little sensuously.For example, dog in might taking a walk runs to the situation of other people or dog suddenly, but derived suddenly and wanted to stop in a hurry under the situation of this derivation at lead-in wire, with the identical direction of direction moves hand or finger is compared to deriving with lead-in wire, sensation as conditioned reflex, to its rightabout, promptly moving to the direction that lead-in wire will be retracted is nature, even the situation of burst also is difficult for makeing mistakes.
Summary of the invention
The present invention is conceived to such operation feeling make, provide a kind of when wanting to stop the lead-in wire derivation, by with the rightabout operation that goes between of above-mentioned spool in the past, just can be with rapidly and the spool of operating reliably lead-in wire than more natural in the past sensation.
Spool of the present invention lead-in wire is by rotatable and be basic premise to being accommodated in the main body cover with the spool that is used to twine lead-in wire with twining state that the side effect has rotatory force.Here, in this manual, for convenience of explanation the side that derives that goes between in the main body cover of spool lead-in wire is called " preceding ", its opposition side, a side of promptly twining lead-in wire is called " back ".
And, in order to address the above problem, spool of the present invention lead-in wire adopts and followingly constitutes: possess brake trigger near the front of the downside of the above-mentioned export mouth of aforementioned body shell, above-mentioned brake trigger can along with the side of deriving lead-in wire in the opposite direction (backward) be pressed in the aforementioned body shell, and to be installed on the aforementioned body shell by the state of the application of force to returning side, when being pressed into above-mentioned brake trigger, brake trigger engages with spool and limits spool and rotate to deriving side.
Above-mentioned formation is applicable to more small-sized spool lead-in wire.When main body cover is holded up, when export mouth was held with a firm grip in palm towards the place ahead, forefinger just in time colluded near the brake trigger that is configured in the export mouth downside front, the shape that the upper surface of main body cover forms and thumb coincide.In when stroll, with this state hold main body cover on one side with forefinger operation brake trigger adjust the derivation of lead-in wire on one side.According to this formation, lead-in wire such as run away suddenly when being pulled dog, be pressed into the derivation that brake trigger just can stop to go between by making the forefinger action that tie tight at (rear of main body cover) to nearby.Therefore, even the burst situation also can operate forthwith with the sensory chaetae of nature.
Preferably, the bolster that above-mentioned brake trigger is provided with abreast by the turning cylinder with spool can joltily be fixed near the position the export mouth of main body cover with shaft type at fore-and-aft direction.According to above-mentioned formation, brake trigger has and good waving angle when keeping operating with forefinger, thereby obtains suitable operability.
In addition, as the brake trigger of above-mentioned formation and the snap fastener of spool, constitute: brake trigger possesses from the hinder marginal part that the closes on spool card claw stop portion to the side-prominent setting of spool, and the lateral surface at the flange that stretches out from the two ends of spool forms only tooth portion of card, push operation by brake trigger makes above-mentioned card claw stop portion end tooth portion with the card of said reel to engage, limit the rotation of spool thus.If such snap fastener, because the advantages of simple of mechanism own, brake trigger and spool have gratifying sense of touch and can engage effectively, therefore also are difficult for breaking down or misoperation.
In addition, in said reel lead-in wire, when the forefinger of tying tight is pressed into brake trigger, can limit the derivation of lead-in wire, and brake trigger returns spool can be rotated once more when unclamping forefinger, thereby the derivation of lead-in wire becomes free.Therefore, when taking a walk under length that will lead-in wire keeps certain state, hope can be carried out locking being pressed under the state of brake trigger.Consider also that as the lockable mechanism of brake trigger the mechanism of for example alternately switching lockup state and released state by being pressed into brake trigger is once more arranged.Complexity improves cost yet this in-house modular construction becomes, and causes the operate miss under the bursty state easily.
Therefore, in spool lead-in wire of the present invention, will be used for the mechanism and the brake trigger split setting of the operation of locking brake trigger.Promptly, lockable mechanism as brake trigger adopts following formation: at the upper surface configuration lock stopping bar that more leans on rear side than the export mouth of main body cover, this locking rod is installed into and can and slides on fore-and-aft direction along the upper surface of aforementioned body shell, if under the state that in main body cover, has been pressed into above-mentioned brake trigger, above-mentioned locking rod is forwards slided, then locking rod engages with brake trigger, and brake trigger is become under the state of restriction spool rotation by locking.
The locking rod that above-mentioned formation relates to is arranged on: the position that thumb just in time catches under main body cover is held state in palm with a firm grip.With forefinger to the action of nearby tying tight and the action that thumb is forwards released because the identical interlock successfully of method firmly can obtain good operability thus.
As the locking rod of above-mentioned formation and the snap fastener of brake trigger, the card that locking rod possesses towards the outstanding setting of brake trigger ends hook portion, and the hinder marginal part formation at brake trigger ends the corresponding hook portion of hook portion with above-mentioned card, forward operation by locking rod makes above-mentioned card end hook portion to engage with the hook portion of above-mentioned brake trigger, under the state that brake trigger is limited in being pressed into, this is rational thus.If such snap fastener, because the advantages of simple of mechanism own, locking rod and brake trigger have gratifying sense of touch and can engage effectively, therefore are difficult for breaking down or misoperation.
In addition, another formation as spool lead-in wire of the present invention, adopt and followingly to constitute: the opposition side at the export mouth of main body cover is provided with handle, between main body cover and handle, form finger and insert the space, front upper at above-mentioned handle possesses brake trigger, above-mentioned brake trigger can be pressed in handle along going up in the opposite direction with the side of deriving lead-in wire, and to be installed on above-mentioned handle by the state of the application of force to returning side, when being pressed into above-mentioned brake trigger, extend the brake arm that is provided with from brake trigger to the spool side and engage, limit spool and rotate to deriving side with spool.
This formation is applicable to the spool lead-in wire more large-scale than aforementioned formation.When four fingers being inserted the handle of holding with a firm grip between the handle be arranged on the main body cover rear portion and the main body cover, and make export mouth when the place ahead, on the brake trigger of the front upper that is disposed at handle, form the shape that forefinger just in time catches on.In when stroll, with this state hold handle on one side with forefinger operation brake trigger adjust the derivation of lead-in wire on one side.Constitute according to this, run away suddenly dog and wait under the situation that lead-in wire is pulled, by the derivation that makes the forefinger action that (handle side) ties tight to nearby just can stop to go between, even so situation about happening suddenly also can successfully operate with the sensation of nature.
The spool lead-in wire of the present invention that constitutes as mentioned above, the direction of operation brake trigger is configured to and opposite in the past direction when wanting to limit the lead-in wire derivation, i.e. the direction that lead-in wire will be retracted.Thus can be with than more natural in the past sensation operation brake trigger, even therefore the situation of burst also can stop the derivation to go between without hesitation rapidly and effectively.
