Description

GERMAN

Staplers with a U-shaped staple saddle and staple pusher and one that extends over both and clamp guides hinged to the clamp saddle are known; becomes the clip pusher pulled back, it will open the stapler.

The automatic opening by pulling back the clip slide is in known arrangements achieved in that the clip guide has a recess on the top in the area of the hinge point has and counter to the action of a spring arranged in the hinge point by a itself on the underside of the clamp saddle supporting the locking bracket against the feed direction the clamp slide can be coupled and slidably guided on the clamp guide and by a Spring is pressed in the direction of the push knife guide, so that the locking bracket when retracted while taking and holding the clip slide engages in the recess and the clip saddle opens automatically and is exposed for inserting staples.

The disadvantage of this known arrangement is that the articulated with the clamp saddle Clamp guide- not fully folded back and the full length of the staple saddle cannot be exposed in order to prevent staple bars Place the filling on the clamp saddle from above; furthermore there is only limited access to the given the ejection of the staples causing parts of the stapling mechanism; thus the arrangement is one required in addition to the feed device of the staple slide on the locking bracket effective thrust spring system necessary.

The object of the invention is the closure between the clamp saddle and the clamp saddle overlapping clamp guide by a locking bar arranged in the clamp saddle like a tilting beam to cause the one in the direction of the push knife Has nose that in, closed position through overlapping slots of the clamp saddle and the clamp guide protrudes and thus holds the clamp guide and clamp saddle in the closed position and the on Opposite end in the area of the staple slide filling position has a crank that is in the way of the Clamp slider or a handle bar firmly connected to the clamp slider protrudes, so that when the clamp slide is withdrawn, the lock between the clamp guide and the clamp saddle is opened; when the clamp saddle is pressed into the clamp guide, the clamp slide is opened released from the locking position caused by the cranking of the locking bar and to Feed of the staples released.

Stapler with U-shaped staple saddle

Skrebba-Werk KG, Lahr (Schwarzw.)

Walter Jopp, Lahr (black and white),
has been named as the inventor

The subject of the invention is further, this locking rail in the clamp saddle without additional so bearing links in an embossed bearing cam so to store that they are inextricably locked against the elasticity of the clamp saddle legs in this bearing cam can be.

In the drawings, an embodiment of the invention is shown. It shows

Fig. 1 is designed according to the features of the invention and shown with the clip guide open Stapler in side view with partial sections in the area of the high pressure, hinged spring and push knife attachment,

Fig. 2 shows a cross section of the stapler with a view of the locking formation between the staple saddle and base plate,

Fig. 3 shows a view from below of the clamp guide and the clamp saddle with the clamp advance and locking mechanism with the clamp guide closed,

Fig. 4 the same view from below, but at the moment that forced by the retracted staple slide Lock release,

Fig. 5 the same view from below, but with the clamp guide now open and the one in completely retracted position held by the locking mechanism,

Fig. 6 shows a section through the clamp saddle alone with a section through the storage of the Locking bar, but locking bar before latching,

Fig. 7 the same section, but latched locking bar.

The stapler consists of a U-shaped cross-sectional shape held in a staple saddle 1, a the staple saddle 1 overlapping, the staples as top and side guides and serving at the front to a staple ejection channel

trained clip guide 2, one of the clip guide 2 in turn overlapping and in the usual Way equipped with a push knife 3 for the staple ejection pressure hood 4, which in a common Joints 5 against one another and opposite a base plate 6 carrying the stapling die are pivotably mounted.

The pressure hood 4 is opposite the clamp guide 2 by a in a retaining tab 9 of the Clamp guide 2 suspended leaf spring 7 in spread position held.

The clamp slide 10 is guided in a known manner on the clamp saddle 1 and in the manner of a slide firmly connected to a handle bracket 11, which allows the clamp slide 10 to be withdrawn even when the handle is closed Clamp guide 2 permitted from the outside. The clamp slide 10 is made by the coil spring 12 pressed in the direction of the staple exit and thus causes the staples to advance.

In the interior of the bracket 1, which is open at the bottom, there is a locking bar designed in the manner of a tilting beam 13 stored, which has a wedge-like closure flap 14 in the area of the staple ejection channel, which extends through locking slots 15 and 16 on the clamp saddle 1 and the clamp guide 2 and the clamp guide 2 against the action of the leaf spring 7 with the clamp saddle 1 according to FIG Fig. 3 holds in the closed position. At the opposite end, the locking rail 13 carries a crank 17 which protrudes into the track of the handle bar 11 connected to the clip slide 10, so that when Withdrawal of the handle 11 into its rear end position, the locking rail 13 by the evasive Movement of the crank 17 executes a tilting movement and thus the closure flap 14 according to Fig. 4 swings out of the lock slot 16 of the clip guide 2 and the lock between Clamp guide 2 and clamp saddle 1 open. After the handlebar 11 slides past the Crank 17 is the locking rail 13 under the action of the closing spring 18 in a direct functional sequence pivoted back into its closed position so that the crank 17 the track of the handle bar locks with the clamp slide 10 according to Fig. 5. When pressing down the staple guide 2 the locking tab 14, which is provided with an inclined contact surface, engages again in the locking slot 16 of the clip guide 2, the resulting pivoting movement of the locking rail 13 and its crank 17 the Grift'bügel 11 with the clip slide 10 for sliding forward and Releases the advance of staples. The locking rail 13 is stored in the clamp saddle 1 by the bearing cam 19. The locking rail 13 is shown in Fig. 6 in an inclined position in the bracket saddle 1 inserted and by pressing down with a hole in the bearing cam 19 on the clamp saddle 1 latched as shown in Fig. 7.
