EP2127813B1 - Magazine for wood marking plates - Google Patents

Abstract

The magazine has a magazine container (10) for accommodating wood marking plates (11). A compression spring (15) spring-loadedly attaches the plates in the container at a removal barrier (18) at a magazine outlet (19). Manually releasable actuators (24, 25) unlock the barrier, which protrudes laterally from the magazine, where the actuators are formed as swing levers. Safety devices (32, 33) lock the actuators at the magazine. The safety devices are held in a locking position by spring mechanisms (34, 35) and are movable against the spring force from the locking position.

Description

The invention relates to a magazine for Holzmarkierungsplättchen, with a magazine container for receiving a plurality of juxtaposed Holzmarkierungsplättchen, with a compression spring for spring-loaded installation of Holzmarkierungsplättchen in the magazine container at a removal lock on the magazine output, and with at least one manually releasable actuator for unlocking the removal lock, the side sticking out of the magazine.

In such, for example, from the prospectus of the applicant "data collection in the forest with System.-Signumat" or from the DE-OS 17 61 200 known magazines can be taken from the magazine in succession by snapping to an impact hammer and then taken directly into the wood to be marked or logs in the forest contained in the magazine wood marking tiles. By dipping the impact hammer in the magazine, the removal lock is pushed apart by the impact hammer, which locks immediately after the removal of a woodmarking plate again for the remaining platelets.

In the known magazines, there is the danger that, for example, when gripping or gripping the magazine container by hand, two opposing actuators are inadvertently actuated, so that thereby the removal lock is unlocked. The wooden marker plate against the removal lock oppressive spring can thereby catapult out the woodmarking platelets from the magazine, which on the one hand makes it necessary to re-collect the platelets and on the other causes the risk of injury.

An object of the present invention is to improve the aforementioned magazine so that an unintentional unlock the removal lock is safely excluded.

This object is achieved by a magazine with the features of claim 1.

By the securing device according to the invention an inadvertent release of the at least one actuator is advantageously prevented, since this safety device is spring-loaded in the blocking position and can be moved out of the blocking position only by movement against the spring force. Only then, the at least one actuator can be selectively operated again, for example, to replace woodmarking tiles or to use new woodmarking tiles.

The measures listed in the dependent claims advantageous refinements and improvements of the claim 1 magazine are possible.

As removal lock two pivotable pawls are advantageously arranged on opposite sides in the magazine container, wherein preferably one of the pawls against each other inwardly pressing spring arrangement is provided so that the pawls resiliently assume their blocking position. They point in an advantageous manner to the magazine output out ramp-like or inclined area, through which they are pushed during insertion of an impact hammer for gripping a Holzmarkierungsplättchens outward into the unlocked position.

The at least one actuating member is expediently designed as a pivoting lever, each pivoting lever having a first arm engaging on a pawl of the removal lock and a second actuating arm projecting laterally out of the magazine. In this case, the two arms expediently extend from a pivot axis to essentially opposite directions.

The safety device advantageously has at least one sliding member which, in the blocking position, at least partially overlaps or engages under the region of the at least one actuating member projecting laterally out of the magazine. As a result, an actuation of the actuator and thus an unlocking of the removal lock is only possible if the at least one slide member is pushed out against the force of the spring device from the blocking position. An unintentional actuation of the actuator is not possible.

In a preferred embodiment, two slide members are slidably guided on opposite outer sides of the magazine, whereby the security is further increased, since only with a movement of both sliding members from the blocking position, the actuation of the actuator is made possible.

In an expedient structural embodiment, the magazine container on the magazine output on a broadening for receiving the at least one actuator or the removal lock on.

An embodiment of the invention is illustrated in the drawing and explained in more detail in the following description. Show it:

FIG. 1

a longitudinal sectional view of the output range of a magazine as an embodiment of the invention, in which a securing device in the blocking position prevents unlocking a Entnahmesper- re at the magazine output, and

FIG. 2

the same embodiment in a deblocked position of the securing device and unlocked removal lock.

The magazine shown as an exemplary embodiment in the two figures essentially consists of a magazine container 10 for receiving a multiplicity of wood marking platelets stacked against one another. The interior of the magazine container 10 has a cross-section which essentially corresponds to that of the wood marking platelets 11 these can be accommodated in the magazine container 10.

Such wood marking plates 11 are usually made of a plastic material and have on one flat side four hook-like fastening elements 12, by which they can be engaged on an impact hammer, not shown, to be hammered into a wood to be marked. For this they have on the opposite flat side anchoring elements 13, which penetrate into the wood when hitting and fix the respective woodmarking plate 11 thereby. This is shown and described in more detail in the above-mentioned prior art.

When inserting the stacked wooden marking plate 11 in the magazine container 10, a contact plate 14 is pressed against the force of a coil spring 15 in the magazine container 10. A removal lock 18 on the magazine exit 19 consisting of two pivotable pawls 16, 17 prevents the wood marking platelets 11 from being pushed out of the magazine container 10 again by the helical spring 15. The two pawls 16, 17 are pivotally mounted on opposite sides in the interior of the magazine container 10 at the magazine outlet 19 and are each pressed by a spring 20, 21 against each other so inward that they lock the wood marking plate 11 to the output. The magazine container 10 has, in the region of the magazine outlet 19, a magazine extension 22, 23 extending to two opposite sides, which serves to receive the two pawls 16, 17 and the springs 20, 21. Furthermore, in this magazine extension 22, 23 two swivel lever 24, 25 formed as actuators pivotally mounted, each having two starting from a pivot axis 26, 27 in substantially opposite directions extending arms 28, 29 and 30, 31 respectively. The two trained for manual actuation as actuation arms arms 30, 31 extend laterally out of the magazine, while the other two arms 28, 29, the pawls 16, 17 so abut that upon compression of the actuating arms formed as arms 30, 31 the other arms 28, 29, the pawls 16, 17 press against the spring force of the springs 20, 21 to the outside and thereby unlock the wood marking plate 11 so that they can get to the outside or can be filled in the magazine container 10.

In the region of the arms 30, 31 projecting laterally out of the magazine, two slide members 32, 33 forming a safety device are guided displaceably parallel to the longitudinal axis of the magazine container 10. They are each due to the force of a spring 34, 35 axially to the arms 30, 31 and overlap them such that an operation is no longer possible or is prevented, as is made FIG. 1 evident.

If you want the arms 30, 31 of the pivot lever 24, 25 squeeze, so must first slide members 32, 33 according to FIG. 2 against the force of the springs 34, 35 are pushed away from the arms 30, 31, only then can the arms 30, 31 are actuated to unlock the magazine exit 19 by pushing apart the pawls 16, 17.

In an alternative, not shown embodiment, the slide members 32, 33, the arms 30, 31 also engage under so as to block or prevent an operation. Instead of sliding members 32, 33 and pivot members can occur, which are pivoted away against a spring force of the arms 30, 31. Both the pivoting direction and the sliding direction can be freely selected. It is only essential that the safety device formed in one case prevents actuation of the pivot lever 24, 25 and in the other case allows movement against a spring arrangement to cancel the blockage.

For gripping a single woodmarking tile 11 by means of an impact hammer, the securing device formed by the sliding elements 32, 33 need not be unlocked. The pawls 16, 17 have the magazine output 19 through a ramp-like slope 36, through which they are at the onset of the wood marking hammer against the force of Springs 20, 21 are pressed outward, so that the uppermost woodmarking plate 11 engages the hammer head and can be removed. Since the pawls 16, 17 are again pressed directly inward when the hammer is brought out, the remaining wooden marking platelets 11 are immediately blocked again.
