Description

The The invention relates to a printing plate closure according to the preamble of claim 1

Known are pressure plate fasteners with a base plate, over which the pressure plate lock on a door, a flap, a hatch or the like is attached. There is a locking arm on the base plate pivotally mounted, which for fastening the pressure plate closure on a doorframe or the like is used. Furthermore, a locking arm is on the base plate arranged pivotally mounted. The locking arm is in the Typically designed so that it rests against the base plate and off this position only when opening and closing the Door against the base plate is pivoted. The locking arm is used for locking opposite to the locking arm the base plate and thus locks the door or the like in the closed Condition and ensures that the door does not accidentally reopen. To the closure arm has a latching projection, which in the closed Condition of the printing plate shutter from a projection of the Arretierarms is engaged behind the locking arm in the closed position to keep. A first pressure plate for opening the door or the like is on the Arretierarm and a second pressure plate for closing the Door or The like arranged on the shutter arm. Usually are in the door or the like two openings let in, in which the two pressure plates in attachment of the printing plate shutter come to rest around these printing plates just press to be able to. To ensure the locking between the lock arm and the base plate, the known Druckplat tenverschlüsse on a leg spring, which the locking arm acted upon in such a way that it against the base plate is pressed. As a result, both the locking arm and the Locking arm held in a fixed position relative to the base plate. If the locking arm against the force of the leg spring against the Base plate pivoted, gives the projection of Arretierarms the Locking projection of the lock arm free, so that the lock arm also can pivot against the base plate and thus the with the base plate connected door or the like against the door frame connected to the shutter arm or the like open leaves.

adversely When using the leg spring is that the leg spring on the one hand, because of the frequent Biegewechselbelastungen after frequent opening and Shut down the door, Flap, hatch or similar breaks and the pressure plate closure is no longer functional. On the other hand, for secure locking of the door or the like and thus for secure locking of the locking arm and the locking arm across from the base plate one possible size Force desirable, which presses the locking arm against the base plate to a sudden opening of the Door or to avoid such. However, with a thigh spring can at the given size only small Transmit forces become.

The The object of the invention is therefore a printing plate closure to provide which a reliable locking of the door or the like across from the door frame or the like, and thus the shutter arm relative to the base plate guaranteed.

The The object of the invention is achieved by a printing plate closure with the characterizing features of claim 1

advantageous Embodiments and developments of the invention are specified in the subclaims.

at the printing plate closure according to the invention is on the base plate a spring holder with a compression spring is arranged, wherein the compression spring acts on the locking arm such that he is pressed to the base plate. Instead of the known leg spring Thus, the pressure plate closure on a compression spring, which is not subject to bending stress, but only along its longitudinal direction is compressed or stretched and thus has a much longer life as a thigh feather. As a result, the overall lifetime of the pressure plate closure increased. In addition, you can transmitted significantly larger forces with a compression spring be as with a comparable leg spring, so the force with which the locking arm and thus also the locking arm in closed state of the pressure plate closure against the base plate is pressed, significantly increased becomes. This improves the security of the door or the like, since more force must be expended to solve the lock, and thus accidental opening the door or the like reliable is avoided.

Preferably the spring holder is arranged approximately perpendicular to the base plate, because in this geometry, the compression spring perpendicular to the locking arm is arranged and thus the force of the compression spring optimally to the Transfer base plate and the locking arm can be.

If the spring holder is rigidly arranged on the base plate, forces occur during the pivoting movement of the locking arm against the base plate, which could damage the spring holder. In addition, in the pivoting movement then the spring stops tion and thus the compression spring is not always arranged perpendicular to the locking arm, so that no optimal force transfer takes place. In a particularly preferred embodiment of the invention, therefore, the spring holder is pivotally mounted on the base plate, in order to combine the rotational movement between the locking arm and base plate optimally with the linear movement of the compression spring can.

Preferably is the spring holder by means of a first leg spring in one held in a substantially vertical position relative to the base plate, so that both in the open as well as in the closed state of the printing plate shutter, so Essentially, if the locking arm does not hit the base plate is pivoted, the spring holder and thus the compression spring vertically to the base plate and the locking arm are arranged to the force to be able to transfer the compression spring optimally to the locking arm. Just while The pivotal movement then becomes the spring retainer against the force the first leg spring from its substantially vertical position pivoted relative to the base plate.

Preferably the spring holder engages through the locking arm to a possible To ensure small volume of the pressure plate closure.

at a particularly advantageous embodiment of the invention is the Spring holder formed essentially of a cylindrical rod, at the free end of a completion plate with a larger diameter is arranged as the diameter of the cylindrical rod, wherein the compression spring between the end plate and the locking arm supported. The cylindrical rod of the spring holder thus penetrates the compression spring. This is the one end of the compression spring on the end plate and the other end of the compression spring on the locking arm. The compression spring is compressed against the spring force to ensure that the locking arm with enough greater Force is applied and pressed against the base plate.

Preferably is a plastic ring between the compression spring and the locking arm arranged. This serves to prevent the locking arm from being damaged to protect by the compression spring, because the compression spring in the pivoting movement between the base plate and Arretierarm is moved against the Arretierarm and thus on the surface of the locking arm would scratch back and forth. In particular, when the compression spring, as in an advantageous embodiment of the invention, made of steel is made, can such damage especially easy to occur. A compression spring made of steel is however for the reason that it has a particularly high hardness and thus transmit large forces even with small size can.

Basically the first pressure plate rigidly connected to the locking arm, in particular even one piece be formed on the locking arm. In a particularly advantageous Embodiment of the invention, however, the first pressure plate is pivotable mounted on the locking arm arranged. This may be the first Pressure plate also not complete even surfaces the door or the like.

Preferably the first pressure plate is acted upon by means of a second leg spring. As a result, the pressure plate becomes relative in a predetermined position held to the locking arm, wherein they are out of position depending on the configuration the surface of the Door or the like can be moved out. The second leg spring ensures however, that the pressure plate rests against the surface of the door, the better To allow gasket.

at a preferred embodiment According to the invention, the first pressure plate has a sealing ring for sealing the first pressure plate against the door or the like to in particular to prevent the ingress of moisture.

Basically also the second pressure plate rigidly connected to the shutter arm, especially even in one piece be molded on locking arm. Preferably, however, is the second Pressure plate mounted pivotally mounted on the lock arm, to possible Unevenness in the surface the door or the like to compensate.

at a particularly advantageous embodiment of the invention, the Base plate an opening on, through which the shutter arm passes through the base plate and which in the closed state of the pressure plate closure by the second pressure plate is closed. This allows one as possible compact design of the pressure plate closure.

Preferably is at the opening or at the second pressure plate a sealing ring arranged to abut the second pressure plate at the opening too here to prevent the ingress of moisture.

advantageously, the locking arm is loaded with a third leg spring, which at opening of the pressure plate closure causes the shutter arm in an opener Position is pivoted, so when opening the pressure plate closure the door or automatically swings open.

Preferably are the base plate, the locking arm and the locking arm off Aluminum made to the pressure plate closure as easy as possible train, so he preferably in aerospace can be used.

The 1a to 1c and 4 show views from different sides and a perspective view of an embodiment of a printing plate closure 10 with a base plate 20 , a locking arm 50 and a locking arm 60 ,

The base plate 20 is a substantially rectangular plate with any number, in this case with four mounting holes 22 for fixing the base plate 20 on a door, flap, hatch or the like, not shown. The base plate 20 has a first pair of fastening projections 23 on, between which a pin 61 is rotatably mounted, on which the shutter arm 60 is arranged so that the shutter arm 60 around the longitudinal axis of the pen 61 swiveling against the base plate 20 is (see in particular 2 and 3 ). The lock arm 60 is slightly curved, with the pin 61 on a jetty 64 of the locking arm 60 which is approximately in the middle of the length of the shutter arm 60 is scheduled. At the first end 60a of the locking arm are fastening means 63 for fastening the locking arm 60 arranged on a door frame or the like, which may be formed for example from a screw with a corresponding nut. At the second end 60b of the locking arm 60 is a second pressure plate 80 arranged, which over a pin 83 pivotally mounted at the second end 60b of the locking arm 60 is arranged (see also 3 ).

The base plate 20 has an opening 21 on which the lock arm 60 with the second free end 60b passes through (s. 3 ). The second printing plate 80 thus comes on the other side of the base plate 20 to lie as the fastening projections 23 for the locking arm 60 , In closed to stand the pressure plate closure 10 lies the second pressure plate 80 at the base plate 20 and closes the opening 21 as it is in 2 is shown by the solid lines. In this condition is also on the base plate 20 attached door in the at the first end 60a of the locking arm 60 arranged door frame closed. The lock arm is with a third leg spring 65 charged (cf. 3 ), which in the open state of the pressure plate closure 10 the locking arm 60 through the opening 21 the base plate 20 pushes, leaving the second pressure plate 80 the opening 21 the base plate 20 releases. A condition when opening the printing plate shutter 10 is in 2 shown with truncated lines. As a result, one on the base plate 20 fixed door against one at the first end 60a of the locking arm 60 pivoted door frame pivoted and the door is thus opened.

To the pressure plate closure 10 locked in the closed state, thus reliably preventing accidental opening of the door, the lock arm has 60 at its second end 60b a locking projection 62 on (cf. 2 and 3 ), which in the closed state of the pressure plate closure 10 from a lead 52 the Arretierarms 50 is under attack, so that the shutter arm 60 in the closed position, in which the second pressure plate 80 at the base plate 20 is present (cf. 2 ) is locked.

This is on the base plate 20 a second pair of fastening projections 24 arranged between which the locking arm 50 is arranged pivotably mounted. The locking arm 50 has a base 51a as well as two substantially perpendicular side surfaces 51b on, which reinforces the Arretierarms 50 and for fixing the locking arm 50 at the base plate 20 serve. The locking arm 50 thus has a substantially U-shaped cross-section. The locking arm 50 is at its first end 50a over the side surfaces 51b at the attachment projections 24 attached. The base plate 51a forms at its at the first end 50a the Arretierarms 50 lying end the projection 52 , which in closed condition of the pressure plate closure 10 the locking projection 62 of the locking arm 60 engages behind and thus arrested. At the second end 50b the Arretierarms 50 is a first printing plate 70 over a pen 73 arranged pivotally mounted. By pressing against the first pressure plate 70 can the locking arm 50 against the base plate 20 be pivoted. This gives the lead 52 the Arretierarms 50 the locking projection 62 of the locking arm 60 free, so that the lock is released and the lock arm 60 with his second end 60b through the opening 21 the base plate 20 swings. If the pressure plate closure is to be locked again, the locking arm 60 against the power of the third leg spring 65 pivoted so that the locking projection 62 behind the projection 52 the Arretierarms 50 engages and the second pressure plate 80 at the base plate 20 is applied.

In order to ensure a secure locking, but the locking arm must 50 be acted upon with a force such that the first end 50a the Arretierarms 50 against the base plate 20 is pressed and thus the lock between the shutter arm 50 and the locking arm 50 by pressing the first pressure plate 70 can only be solved if this power is overcome.

This is on the base plate 20 a spring holder 30 arranged, which consists essentially of a cylindrical rod 31 exists, at its first free end 31a an end plate 32 is arranged, which has a larger diameter than the diameter of the cylindrical rod 31 having. The spring holder 30 is at the second free end 31b of the cylindrical rod 31 about one in a direction transverse to the longitudinal axis of the cylindrical rod 31 extending bore arranged pin 33 swiveling against the base plate 20 stored (see. 3 ). In the base area 51a the Arretierarms 50 is an opening 53 arranged, through which the spring holder 30 starting from the base plate 20 protrudes (cf. 3 ). The cylindrical rod 31 passes through a coil spring, which in the present case as a compression spring 40 acts. The compression spring 40 supports itself with its one end against the end plate 32 and, since the spring holder 30 through the opening 53 the base area 51a the Arretierarms protrudes, with its other end against the base 51a the Arretierarms 50 from. Because the compression spring 40 thus compressed against its spring force and is under tension, it exerts a force that the Arretierarm 50 , in particular its base area 51a against the base plate 20 pressed. By a substantially vertical arrangement of the spring holder 30 opposite the base plate 20 becomes the spring force of the compression spring 40 optimal in the locking arm 50 initiated, so that the maximum possible force is exercised.

So that the spring holder 30 despite the pivotable mounting in the substantially vertical orientation relative to the base plate 20 is held, is the spring holder 30 with a first leg spring applied (not shown). The pivotal mounting of the spring holder 30 is at the pivotal movement of the Arretierarms 50 opposite the base plate 20 advantageous because the rotational movement of the Arretierarms 50 in this way with the linear movement of the compression spring 40 Can be combined because the spring holder 30 the pivoting movement of the Arretierarms 50 can understand. In addition, the forces acting on the spring retainer 30 act during the pivoting movement, damped, so that less damage to the spring holder 30 occur. To further damage the Arretierarms 50 by the movement of the compression spring 40 on the ground 51a during the pivoting movement of the locking arm 50 against the base plate 20 to prevent is between the compression spring 40 and the base area 51a a plastic ring 42 arranged. Especially when the compression spring 40 made of steel and the components of the pressure plate closure 10 , in particular the base plate 20 , the locking arm 50 and the lock arm 60 Made of aluminum, a protection of the aluminum components against scratching by the steel spring is needed.

With it through the opening 21 the base plate 20 passing through the second pressure plate 80 in the closed state of the pressure plate closure 10 and thus closed with the door closed, no moisture can penetrate, the opening points 21 a second sealing ring 87 on which the opening 21 against the second pressure plate 80 seals. To ensure a particularly good seal, it runs in the opening 21 lying side of the second printing plate 70 conical, so that manufacturing tolerances or material fatigue of the sealing ring 87 can be compensated. The sealing ring 87 may alternatively also on the second pressure plate 80 be arranged to the second pressure plate 80 against the opening 21 seal.

The first printing plate 70 comes to lie in an opening, not shown, of the door or the like. To seal this opening against the ingress of moisture, also has the first pressure plate 70 a first sealing ring 77 on (see in particular 1a and 3 ). To allow a particularly good sealing of the opening in the door, the pivotally mounted first pressure plate 70 with a second leg spring 75 subjected to the first pressure plate 70 forces in a certain relative position relative to the locking arm. This can cause bumps on the door surface on which the first pressure plate 70 it comes to lie, be balanced and it is guaranteed that even the first pressure plate 70 always as good as possible the door surface rests and causes a good seal.
