DE3316199A1 - Furniture lock which can be used with a plurality of different modes of fastening - Google Patents

Abstract

The invention relates to a preferably mounted-on furniture lock with a central keyhole (6), which can preferably be used for all modes of fastening, namely on the right, on the left, at the top and at the bottom, but not exclusively for these. The lock assembly is designed virtually completely symmetrically to the transverse mid-axis (15) of the lock. The tumbler (17) is materially in one piece and is mounted in a floating manner relative to the transverse mid-axis (15) of the lock by means of a spring element (23). A possibility is shown how, with a hollow-bored stalk-type key customary in the sector, that is to say commercially conventional, a lock with a central keyhole (6) can be made capable of use for a plurality of modes of fastening by means of a key-pin rocker (33) which allows a plurality of key pins (35 and 36) to be disengaged and engaged (Figure 2). <IMAGE>

The invention relates to a furniture lock with, for example, a central keyhole which can be used in several types of attack and sliding bolt and tumbler that can be operated directly by means of a lock bit.

Stand ύ & τ Teelfoolk

A furniture lock that can be used on the right and left is previously known from DE-GM 1 789 129, but not at the same time tils drawer and flap lock, so not for all types of attachment, is usable.

In addition, the lock setup is complicated by a designed tumbler, which consists of several high-quality machined individual parts and two profiled key pins, relatively complex.

Finally, this furniture lock has the disadvantage that the door hole for the lock penetration for actuation of the lock is not arranged centrally to the lock or the lock is not equipped with commercially available keys and key sockets can be operated.

The task of the Lrfinduruj is to create a furniture lock according to the generic term of claim 1 to that effect to improve that it can be used e.g. for several types of attachment - e.g. right, left, above, below - with more central

A lock according to the invention can be designed so that it can be used for all types of stops without conversion for the applicant in their DE-AS 21 32 957 described in their DE-AS 21 32 957. All you need is comit _: a basic lock to meet ^{all requirements within a specified area 1.} However, it is not mandatory! necessary to use the lock for all types of attacks.

The previous individual construction methods or manipulations on the lock ¹ submitted can thus be omitted. Such a lock eliminates errors in ordering and order processing, because it can always be used within the specified range

of the lock transverse center axis 15 is identical, so that these tour pins 16, 17 are also symmetrical to the lock transverse center axis 15 lie. The tour pins 16 and 17 run perpendicular to the sliding bolt 14 in the direction of the tumbler 13.

, Diametrically opposite to tour pins 16 and 17 are ι tour pins 18 and 19 also arranged on tumbler 13, i.e. with the tumbler 13 is on each side of the lock transverse center axis 15 also a tour pin 18 and 19 each connected in one piece. The tour pins 16, 17, 18 and 19 are located with respect to their longitudinal axes 20 and 21 at completely one or pushed out sliding bolt 14 coaxially to one another.

In the position of the sliding bolt 14 shown with dash-dotted lines, the tour pins 16, 17 of the tumbler occur 13 behind the tour pins 18, 19 of the sliding bolt 14, so that; this can no longer be pushed into the lock, is therefore blocked against unintentional movement.

In the lock housing 8, a spring chamber 22 is arranged, which extends transversely to the lock transverse center axis 15 and is arranged symmetrically with respect to the lock transverse center axis 15. ι In the spring chamber 22 is disposed in the illustrated embodiments, designed as a helical compression spring spring element 23, which is interposed between cam 24 and 25 under prestress [. The cams 24 and 25 are arranged in one piece on the underside of the tumbler 13 facing the sliding bolt 14. The center distance of the cams 24 and 25 from the lock transverse center axis 15 is also the same.

The wall of the spring chamber 22 facing the sliding bolt 14 is denoted by the reference number 26, while the reference number 27 represents an opposite wall of the spring chamber 23. Between the two walls 26 and; 27 come to rest the cams 24 and 25, so that the \ spring element 23 is supported against the facing end faces ¹ 30 and 31 of the spring chamber 22 and thereby the tendency

has to center the tumbler 13 in relation to the lock transverse center axis 15, i.e. to bring it into the starting position.

' As shown in FIG. 2, both the sliding bolt are; 14 as well as the guard locking 13 each with a centric release! saving 28 or 29 of relatively large cross-sectional dimensions; see. The central keyhole ends in this area; 6 in the lock cover 30. This central keyhole j 6 has in the manner shown in the figures, embodiments of '■ two 180 degrees offset from one another extending recesses

6a for the “Lad” stop and 6b for the “flap” stop, I whose longitudinal axes 31 and 32 run parallel to one another and to the I transverse center axis 15 of the lock.

During this exclusion movement, the tour pins 18, 20, 19, 21 change their position, so to speak, so that the front of the Exclusion movement of the sliding bolt 14 located in front of the tour pins of the sliding bolt 14 tour pins of the tumbler 13 come to rest at the end of the exclusion movement of the sliding bolt 14 behind the tour pins of the sliding bolt 14, i.e.

At the end of the exclusion movement of the sliding bolt 14, the spring element 23 brings the tumbler 13 into the one described Locked position by shifting in direction B, so that the tumbler 13 in this position 'is its central starting position in relation to Schloßq.uermittenachse 15 has taken again.

When the sliding bolt 14 is closed inwards, the key bit arrives of the hollow handle wrench against the control surface 44, whereby the tumbler 13 again against the restoring force the spring 23 is pressed in the direction T, so that the movements can be reversed, so to speak. The spring element 23 is compressed again, the key beard moves the sliding bolt 14, the center points of the tour pens 18, 20 19, 21 to a certain extent turn by 180

When using the other recess 6b, the operations are
accordingly, as all notches and control surfaces are on
the other side of the lock transverse center axis 15 accordingly
exist because the lock mechanism is also designed symmetrically to that extent. Before using the recess j 6b, the key arbor rocker according to FIG. 6 is to be repositioned using a tool. If, on the other hand, this lock is to be switched from one type of attack to the other - right or left - the key-arbor rocker 33 is switched over by the key bit (FIG. 1).
