Description

The invention falls within the field of bookbinding and clamping aids. the storage of documents, namely, in the field of document editing and depositing aids, in particular those comprising a means of clamping down the holes with which the documents provided for clamping are provided, namely a two-part clamping assembly comprising a fixed part with at least two mandrels and a movable part with thus at least two thorns.

The invention is based on the problem of how, in the case of a clamping mechanism comprising a base plate and a pair of the latter rigidly connected spikes and two swivels and against the aforementioned spikes, due to the displacement of the corresponding control lever of the pressure springs, the lever will also be held in the open position the said pair of thorns are in such a position that the user will be able to scroll in the mechanism of the clamped leaves, the flawless operation of the mechanism being ensured despite the considerable simplification of the structural design, in particular the base plate.

The clamping mechanism of the binder is described in WO 20/04082961 respectively. EP 1 606 122. Such a mechanism consists of a base plate having two rigidly connected rigid mandrels with said plate and two on said base plate of pivotally spaced mandrels, which are connected to each other via a properly rigid intermediate section and therefore both are movable at the same time by means of a suitable handle, which is mounted on a support, which is provided approximately in the central region of the base plate and forms part of the latter or. is rigidly connected to the latter.

The baseplate includes appropriate reinforcements and openings for mounting on the available registrar covers. In the two corners of one of the longer sides of this panel, each of them is rigidly fixed to each other at a suitable distance by a fixed motion, the free ends of which are curved in the direction of the free ends of the movable mandrels. In the area of the rest of the longer side, movable spikes are attached in their respective beds, which are connected to each other via an intermediate section, which can in principle be overlapped trapezoidly. as letters U. The said beds are generally located near the longitudinal edge of the baseplate, while the central area of the intermediate section through which the movable mandrel is connected is displaced in the interior i.e. towards the central region of the baseplate and running parallel to the aforementioned edge of the plate.

Further, at least approximately in the central region of the base plate there is a support projecting from the plane of the base plate at least substantially perpendicular to said plane and at its free end at a distance from the base plate to form a pivot of the lever to move the movable mandrel of the mechanism. Said lever is arranged in a vertical plane parallel to said longitudinal edges of the base plate, and the axis of bearing of said lever extends through said carrier in a direction perpendicular to said longitudinal edges of the base plate and parallel to the plane of the base plate. Further on the said • 9

the crank at an appropriate distance from the pivot point an eccentrically positioned roller element adapted for rolling along said central region of the intermediate section between the two movable webs. For this purpose, the lever is L-shaped, with the longer arm being the control arm, the rolling element at the end of the shorter arm, and the arm itself at the intersection of the arms. Said intermediate section is further supported by a spring, in particular by a bending spring, so that due to the swinging of the lever along said central section, the movable roller element is selected or presses the intermediate element against the force of said spring or. permits said spring to dislodge the central portion, as far as the rolling element permits, in each case, depending on the position of the lever in each case, with the movable arms tilting relative to the plane of the base plate, thereby either approaching or moving away from the movable arms.

When the movable spikes are deflected away from the two fixed spikes, the mechanism is open and in such a position it is possible to insert or insert into the binder. remove leaves from it. The intermediate section of the movable arms is, thanks to the spring, pushed away from the base plate, the control arm of the lever is also deflected away from the base plate and extends into the area between the open fixed and movable mandrel located on the side of said control arm of the lever.

By moving the lever control lever in the direction toward the plane of the base plate, the rolling element moves along the central region of the intermediate section between the movable arms and presses said central region in the direction towards the plane of the base plate and therefore against the force of the spring. When the rolling element crosses a line perpendicular to the plane of the base plate through the pivot of the crank on the center bracket, the free end of each movable mandrel coaxially rests against the free end of each adjacent movable mandrel. As the lever allows further movement of the rolling element over the aforementioned line, the lever locks in this position and stays in this position, thus closing the mechanism.

This mechanism is undoubtedly very reliable and efficient, as it enables fast and reliable clamping of a relatively large number of leaves. The problem arises when the user wants to scroll through clamped sheets or e.g. rearrange the contents of the binder, especially e.g. change the order of pinned leaves or the like. In such a case, the scrolling i.e. movement of leaves from the area of fixed spines to the region of movable spines or vice versa, otherwise possible, but provided that the mechanism is closed. However, in order to change the order of the leaves, it is necessary to open and temporarily remove the leaves by unscrewing the mandrel and then reinserting them in a different order, then closing the mechanism by swinging the handle and tilting the movable mandrels. In the case of sorted sheets, it is often necessary to repeat the sequence of these steps several times, which is relatively time-consuming and uncomfortable for the user. At the same time, the manufacture of such a mechanism itself is associated with the relatively complicated installation of springs in the base plate. Because of its specific characteristics and requirements, the spring consists of a different, much more flexible and also harder material than the material of the base plate itself. Accordingly, a suitable spot for mounting the spring must be formed in the base plate, which is otherwise made by punching and reshaping the steel plate, then inserting the spring and then fixing it in the appropriate position in the further step of the base plate. All of these steps must be carried out very carefully, since otherwise the spring suspension may be leveled during use, which may result in malfunctioning of the spring and thus a malfunction of the whole mechanism. Therefore, it would be desirable if it could be avoided without prejudice to the reliability of the operation of the mechanism of the presence of said spring and thus the said installation step of the spring.

EP 1 226 987 proposes a substantially similar mechanism in which a base plate is again available with rigidly fixed fixed braces and a central support on which the pivot of the lever is located. The movable spikes are again pivotally supported on the base plate and interconnected by an intermediate section whose central region of the direction towards the plane of the base plate is pressed with the help of an eccentrically spaced roller element on the lever, and at the same time said intermediate section is again removed from the plane of the base plate by springs mounted on the baseplate below said central region of the intermediate section.

The purpose of this solution is to enable scrolling or rearranging, e.g. changing the order in the clamp register, even when the mechanism is open. This means that even with more complex sorting, there is no need for multiple openings. closing mechanism. In order to prevent the lever from projecting into the area between the non-movable and the associated movable mandrel on the side of the control arm, in this case, due to the presence of an appropriate restraint tab on the base plate, in the area immediately adjacent to the central area of the intermediate section between the movable arms in the direction of the control arm in the direction of the control arm the plane of the base plate is limited. This prevents the lever control arm from entering the area between the open fixed and movable boom after opening the mechanism, which generally prevents scrolling, but thanks to the limiting tab mentioned above, its movement is enabled only to such an extent that it also gives control when the mechanism is open. the limb is still kept relatively close to the plane of the base plate and at least at a distance from the motionless and movable limb that the movement of the leaves is still unimpeded. In this case, a spring is still mounted on the plate, which in the context of what has been said so far is considered a drawback. In addition, scrolling is enabled solely on the basis of a decrease in the stroke of the lever. Therefore, if, after opening the mechanism, the movable and immovable mandrel is opened for a certain distance with a smaller stroke of the lever, then the transmission must be changed accordingly.

relationship. This either means that a greater force must be available on the lever or the mechanism itself is subjected to greater stresses and, consequently, deformation. Since these mechanisms are undoubtedly large-scale products, which must nevertheless also meet the stringent requirements for safe and reliable use, increasing the closing force is fundamentally unacceptable, and increasing deformation leads either to unreliable operation or shorter product life. related to other measures, e.g. introducing more expensive materials or increasing the dimensions of the components, which in turn is associated with an increase in weight and higher manufacturing costs.

Further, WO 2005/047015 describes a binder mechanism, which also comprises a base plate, a pair of rigidly coupled rigid ones, and a pair using a suitable movable mandrel handle. In this case, the movable spikes are also pivotally mounted on the base plate and interconnected by an intermediate section supported by a spring mounted in the base plate. Said lever is, like in the cases discussed above, pivotally mounted on a support on the base plate and adapted to cooperate with said intermediate section of the movable mandrels. However, in this case, e.g. an eccentrically positioned roller element on the handle, but a characteristic and preformed curve formed around a pivoting running circumferential edge at the base of a circularly and centrally positioned working area of the crank, which in this case is essentially based on the principles of a classical camshaft. In this way, by rotating the lever around said pivot in a predetermined manner, depending on the angle of rotation of the lever, the distance between the pivot and the end point on said circumferential edge is varied, in which the lever always rests on the intermediate section and the latter pushes against the force of the spring. The aforementioned source particularly emphasizes three possible angular positions of the lever, namely the first position in which, with the mechanism closed, the lever is locked and is located near the plane of the base plate, which enables, among other things, scrolling, while in the second position, thanks to a conveniently selected gear

the mechanism gradually opens or closes the mechanism, the lever being rotated away from the plane of the base plate and thus the leafing is disabled, and in the third position, the lever is rotated practically 180 degrees around the pivot relative to the first position; In this position, the mechanism is open, and thanks to the position of the lever directly on the plane of the base plate, leafing is also possible in the open state of the mechanism. Even in this case, a spring is still mounted on the base plate, which presses the intermediate section between the movable webs towards the camshaft edge. In addition, the projection of the lever is almost perpendicular to the plane of the base plate in the second position. When the lever is located near the plane of the baseplate, it is relatively exposed to pinching, knocking and other damage. In the case of said projection in a direction perpendicular to the plane of the base plate, the free end of the lever is substantially distant from the plane of the base plate and also from the pivot of the lever itself, therefore any load of the lever in the direction transverse to the axis of the pivot, for example by an unintentional blow with a hand, sleeves or even the fall of the binder to the floor can cause extremely high local loads and deformations in the pivot area, resulting in breathability or even inapplicability of the mechanism.

The present invention relates to a control mechanism of the binder, such mechanism consists of a base plate and a clamping assembly, which is pivotally attached to said plate and operated by a control lever which is also pivotally attached to said plate. In this case, on the base plate near one longitudinal side, there are provided two mutually spaced spaced approximately perpendicular to the plane of the plate of rigid and fixed rigidly connected non-moving spikes. In the central region of said plate there is a support, and in the area of the opposite longitudinal side there are provided beds for bearing the clamping assembly on the base plate. The uniquely designed control unit comprises two to cooperate with the aforementioned mandrels in terms of the possibility of interlocking in the axial alignment of the adapted movable mandrels, between which an intermediate section is moved in the direction of said carrier, and between said mandrels there are provided bearing regions , with which the assembly is pivotally mounted in the base plate bearings. Furthermore, the lever consisting of at least the working area and the control arm is pivotally connected to the base plate carrier in the pivot and adapted to cooperate with the clamping assembly.

According to the invention, it is proposed that said control lever of the mechanism in its working area be provided with a guide in which a slider is arranged for engagement with the intermediate section of the clamping assembly, the pivot of said lever being at least to some extent permanently elastically deformable carrier above said guide and therefore at a greater distance from the plane of the base plate than said guide. At the same time, said slider along the guide and also along the intermediate section of the control assembly is movable and therewith, sensibly along the plane of the base plate, and at the same time together with the said intermediate section of the control assembly, also makes sense each time towards the base plate or. away from the baseplate. The crank pivot is arranged on the base plate carrier in the region of the working area of the crank that is farthest from the base plate (1). Further, the slide has a slider movable along the guide here and movable there, and at the same time preferably around its axis and rotatable relative to the pivot.

Said slider is preferably fork-shaped and comprises vertically spaced arms, one of which is further from the base plate and the other is less spaced, and an intermediate section of the clamp assembly is slidably moved between said arms.

Further, said guide is preferably designed as a curved guide whose longitudinal line is drawn in the direction of the base plate. In this case, the minimum distance between the slider and the plane of the base plate is preferably available in the slider position

in the line of normal to the plane of the base plate passing through the pivot, and the distance between the slider and the plane of the base plate in one of the end positions of the slide in the guide is greater than the aforementioned distance in the normal range through the pivot. In a further possible embodiment, the curved straight line of the guide is asymmetrical with respect to the normal to the plane of the base plate passing through the pivot, so that the distance of the slider from the plane of the base plate in the final position in the guide on the side of the control arm of the lever is greater than the distance between the plane of the base plate and the slider in his remaining final position in the lead.

The mechanism of the invention will now be explained in greater detail on the basis of an embodiment illustrated in the accompanying drawing showing

FIG. 1 front clamping mechanism of the binder;

FIG. 2 the same clamping mechanism, this time in the rear view;

FIG. 3 shows the clamping mechanism in the rear spatial view, but at a different angle to FIG. 2;

FIG. 4 clamping mechanism in the floor plan;

FIG. 5 clamping mechanism in side view;

FIG. 6 is a clamping mechanism in the view from the opposite side as in FIG. 5.

The clamping mechanism consists of a base plate 1 with rigidly fixed movable mandrels 11, 12 and a control arm carrier 13, as well as a clamping assembly 2 consisting of two movable toms 21, 22.

The base plate 1 of the mechanism according to the invention is designed in the simplest possible way and comprises suitable reinforcements 14, fixing openings 15 and position openings 16, with preferentially imprinted and riveted fixed arms 11, 12 attached to plate 1. longitudinal sides 18 are provided beds 19 ', 19, in which the clamping assembly 2 is rotatably attached to plate 1.

19 ', 19 are, in the example shown, performed in a relatively simple manner by means of bending or bending. bending the corresponding recesses of the material of the plate 1 itself in the area of the longitudinal side 18. Further, the base plate 1 is provided with a carrier 13 of the handle 3, which is arranged approximately in the central region and is arranged substantially perpendicular to the plane of the base plate 1. Said carrier 13 is designed relatively elastic, which means that it is capable of permanently transmitting deformations of predetermined dimensions in a direction perpendicular to the plane of the base plate 1 and away from the plate 1.

The clamping assembly 2 is uniquely designed and consists of movable mandrels 21, 22 and bearing regions 23, 24 which are inserted in said beds 19 ', 19 of the base plate 1, as well as of the intermediate section 25, which is displaced towards the central region of the plate or. carrier 13. This refers to the intermediate section 25 with respect to said beds 19 ', 19, around which, in principle, at least for a fixed as rotatable entire clamping assembly 2, together with movable mandrels 21, 22 and also bearing areas 23, 24, is pivotally or pivotally mounted. . eccentric. The control lever 3, which is pivotally fastened to said mount 13 in the area of pivot 31, consists of a work area 33 and a control arm 32. Said pivot 31 of the lever 3 is located on the top, further away from the base plate 1 and the intermediate section 25 of the clamping assembly 2 further away. section of the working area 31 of the lever 3.

In the working area 33 of the lever 3, there is provided a guide 331 below the pivot 13, namely between the latter and the base plate 1, in which a slider 333 is displaced along the latter as a fork with at least two arms 333 ', 333. The guide 331 is preferably curved. and runs along a predetermined curve selected according to the position of said pivot 31 and the respective kinematic conditions in relation to the central section 25 of the control unit 2. The movable and generally rotatable slider 333 is arranged along the associated guide 331 to cooperate with the intermediate section • · the clamping assembly 2 which, in the assembled state of the mechanism according to the invention, is located between said arms 333 ', 333 of slider 333.

The control arm 32 of the lever 3 is preferably uniformly aligned with said central region 33 of the lever 3 and is relatively rigid on the one hand and on the other hand designed to allow comfortable handling of the lever 3 and thereby control the whole mechanism of the invention.

When the base plate 1 in the region of the mounting openings 15 is preferably secured by means of a sketch of the non-shown rivets near the back of the respective binder, by moving the control arm 32 of the lever 3 and subsequently moving the slider 333 according to FIG. 1 or 2 to the left, a movement of the intermediate section 25 of the clamping assembly 2 is achieved in the direction of the base plate 1, which results in each of the movable splines 21, 22 being aligned axially to the respective fixed spline 11, 12 in the position when the slider 333 is closest to the base position 1, when at the same time the carrier 13 is elastically deformed and even before the slider 333 in the guide 331 of the working area 33 of the lever 3 reaches an extreme point in the guide 331. This is followed by a further movement of the lever 3 towards the plate 1 thanks to curvature of the guide 331 in the direction away from the base plate 1, thanks in particular to the release of loads and elimination of deformations in the carrier 13, causes the lever 3 to engage there without opening the movable mandrel 21, 22 and the non-movable mandrel 11, 12 in each case. near base plate 1, and therefore at a relatively large distance from the mandrels 11, 21, scrolling through the binder stov certainly possible.

When the user wants to either insert at least one further sheet or remove at least one of the previously mounted sheets from the recorder, by pushing the control arm 32 of the lever 3 in the direction away from the plate, the slider 333 moves in the right direction according to FIG. 1 or 2, which leads to the offset of the intermediate section 25 of the clamping assembly 2 in the direction away from the base plate 1, whereby the movable mandrel 21, 22 is deflected due to the rotation of the bearing sections 23, 24 in the bays 19 ', 19, thereby moving away from the stationary ones. thorns 11, 12. The angle of deflection of said thorns 21, 22 with respect to thorns 11, 12 and. with respect to the plane of the base plate 1 oz. the rotation of the control arm 32 of the lever 3 depends on the length and the run of the guide 331 in the working area 33 of the lever 3. By choosing the length and curvature of said guide 331, it is possible to achieve sufficient opening of the thorns 21, 22 and 11, 12 with only such a rotation of the lever 3, that the control arm 32 of the lever 3, even with fully open mandrels 11, 12, 21, 22, is at a tolerance distance from the mandrels 11, 21, nonetheless, it is still possible to scroll through the contents of the binder, which means that even for open mandrels 11, 21, it is possible to move the leaves from the non-movable mandrel 11 to the movable mandrel 21, or vice versa, without in any way obstructing the control arm 32 of the lever 3.
