The technical problem to be solved in the present invention is:
(1) loose contact of anti-stopping bar and protuberance is more reliably needed.
Namely, because the base end side of bar and protuberance carry out point cantact, so the possibility of wearing and tearing occurs the ad-hoc location that there are any one party or two sides.
(2) in addition, although need to continue the recuperability of opposing spring in order to closed condition two boards being held in loose-leaf binder and stand the weight etc. of the data that loose-leaf binder binds etc., but under the state of point cantact, also to consider the situation that the base end side of bar can be deviate from from protuberance, thus need the closed condition continuing maintenance loose-leaf binder more reliably.
Summary of the invention
In view of the above problems, the invention provides a kind of loose-leaf binder improved further above-mentioned existing loose-leaf binder.
Loose-leaf binder according to the present invention comprises: the first attaching parts of tabular, are provided with Semicircular binding part; Second attaching parts of tabular, abut with the first attaching parts, and are provided with Semicircular binding part; Forcing unit, exerts a force at least one opposite side to front cover body in the first attaching parts and the second attaching parts at ordinary times; First attaching parts fixed part and the second attaching parts fixed part, assigned position is remained on relative to front cover body respectively by with the limit of the relative side, limit mutually abutted in the first attaching parts and the second attaching parts, and can with this position for benchmark makes each attaching parts rotate; Cam, is arranged on the side relative with front cover body relative to the first attaching parts and the second attaching parts, for limiting in the first attaching parts and the second attaching parts the amount of spin of at least one; Bearing, is limited in the turning cylinder of the cam on front cover body on the assigned position relative to front cover body; And operating unit, be arranged on cam.
Cam is configured to abut with at least one in the first attaching parts and the second attaching parts.
The attaching parts abutted with cam in first attaching parts and the second attaching parts are provided with protrusion, and protrusion is for preventing the rotation of cam under the state that the top ends of each binding part is against each other.
Protrusion is configured at least contact on the straight line almost parallel with the turning cylinder of cam with cam under the closed condition that the top ends of binding part is against each other.
Thereby, it is possible to stably keep cam in off position.
Specifically, owing to being made binding part by operation operating unit from closed condition to the open state change that the top ends of binding part does not abut each other, so descend forcing unit applied force the strongest in off position, under open state, then there is no forcing unit applied force, thus can in off position under stably keep cam.
In addition, under the closed condition that applied force is the strongest, protrusion and cam be not on one point on carry out the point cantact that contacts, so the problems of the easy wearing and tearing of any one or two can be solved in protrusion and cam.
Preferred protrusion is configured to lower maximum with the contact area of cam in off position.
Thereby, it is possible to more stably keep cam in off position, and the closed condition that can easily keep forcing unit applied force maximum.
Preferred protrusion is lower and cam surface in off position.
Thereby, it is possible to more stably keep cam in off position, and the closed condition that can easily keep forcing unit applied force maximum.
Preferred protrusion has the higher and inclined-plane that side that is that do not connect is lower, the side be connected with another attaching parts, and inclined-plane abuts with the cam be under closed condition.
Thus, in off position, inclined-plane can be in the parastate relative to front cover body level with the cam forming shutoff device, further stably can keep cam, and the closed condition that can easily keep forcing unit applied force maximum.
Preferred inclined-plane is set up to descend the angle almost parallel with front cover body in off position.
Thus, in off position, inclined-plane can be in the parastate relative to front cover body level with the cam forming shutoff device, stably can keep cam, and the closed condition that can easily keep forcing unit applied force maximum.
In addition, have also contemplated that, on protrusion, inclined-plane is not set, and inclined-plane is set in cam side, but, consider that when being especially made of resin cam etc., cam becomes easy wearing and tearing, and be difficult to maintain closed condition, thus the periphery of cam is made parallel with the turning cylinder of cam, be difficult to wearing and tearing to make cam.
According to said structure of the present invention, obtain following technique effect.
Namely, can in off position under more stably keep cam, more easily can keep the closed condition that forcing unit applied force is maximum.
And in off position, inclined-plane can be in the parastate relative to front cover body level with the cam forming shutoff device, further stably can keep cam.
And, can to prevent in the protrusion that easily produces when protrusion and cam one point cantact and cam any one or two that the situation of wearing and tearing occurs further.
