Definitions

  • the invention relates to a lock with a housing according to the preamble of claim 1.
  • Locks of the aforementioned type are known in numerous designs, see e.g. FR-A-2 386 670.
  • the well-known lock consists of numerous individual parts and is too large.
  • the invention has for its object to minimize a lock of the aforementioned type, that is to create a lock that consists of a minimum of parts. In addition, the dimensions are to be reduced. This object is achieved by the features of the characterizing part of claim 1.
  • the lock according to the invention - apart from a key and a possibly necessary cover - consists of only two parts, the housing and the rotary bolt. This is the smallest possible number of parts, if one of the individual parts - the rotary latch - in relation to the other individual part - the housing - has to be moved in order to fulfill the function of an object - the lock. In particular, no separate springs are required for the tumblers.
  • the lock chosen as an exemplary embodiment has a housing 1 and a rotary latch 2 guided in the housing.
  • the rotary bolt 2 is held in its limit positions offset by 90 o in a manner still to be described, each with a tumbler 11.
  • the rotary latch is actuated from one limit position to the other and back with the aid of a key 3.
  • the entire rotary latch 2 is injection molded from a plastic part.
  • the entire housing 1, including the tumblers 11, is injection molded from a plastic part.
  • POM - according to DIN 7728 - is preferred as the plastic, namely polyacetal resin.
  • the housing 1 is formed from a rear plate 12 and two lateral strips 13 running parallel to one another.
  • a bore 14 is provided in the plate 12 for receiving the rotary latch 2.
  • the two side strips 13 have different widths.
  • One of the tumblers 11 is formed on each of the strips 13.
  • Each tumbler 11 is formed from a projection 15 projecting beyond the inside of the strip 13 and a recess 16 machined into the strip 13 at a distance from the projection 15.
  • the surfaces of the recess 16 run like those of the protrusion 15.
  • the web thus formed between the outer and inner surface of the protrusion 15 has any shape if it only ensures maximum suspension effect.
  • each projection 15 has the shape of an acute-angled triangle in the end view. Consequently, the recess 16 also has the shape of an acute-angled triangle in the adjoining part. The triangle can be isosceles or unequal.
  • the recess 16 is of any design. In the exemplary embodiment, a rectangular part adjoins the part with an acute angle in the view. The described design of the tumbler 11 ensures its resilient-elastic properties in order to engage in the rotary latch 2 and to hold it in the assigned limit position.
  • the rotary latch 2 is provided on one end face with a hollow pin 21. With the hollow pin 21, the rotary latch 2 engages in the bore 14 of the housing 1.
  • the rotary latch 2 is provided with a key channel 22 on the end face opposite the hollow pin 21.
  • An annular recess 23 connects radially to the key channel 22.
  • the recess 23 is limited by two stops 24.
  • the stops 24 are arranged at right angles to one another.
  • the extension of the key channel 22 forms the inner wall of the hollow pin 21.
  • a comb-like projection 25 is provided essentially centrally between the two end faces on the rotary latch 2. On the circumference of the comb-like projection 25, notches 26 are made offset to one another. One of the tumblers 11 engages in one notch 26 in one of the limit positions.
  • the comb-like projection 25 is asymmetrical. Its part forming the exclusion part, shown on the right in the drawings, is longer than the other part shown in the drawings below.
  • the comb-like projection 25 has the effect of an eccentric.
  • the key 3 is inserted into the key channel 22 with a vertical beard.
  • the key 3 is turned clockwise, it takes the rotary bolt 2 in contact with the vertically arranged stop 24 against the action of the tumbler 11 on the bar 13 on the right in the drawing.
  • the notch in the drawing engages with the tumbler 11 formed on the left bar 13.
  • the castle is now excluded; the longer part of the projection 25 projects beyond the adjacent edge of the housing 1.
  • the key 3 can be turned counterclockwise by 90 ° within the recess 23 and removed. To open the lock, the described process is carried out counterclockwise after inserting the key 3. At the end of the opening process, the position of the lock shown in the drawing is reached again. The key can be removed by turning it clockwise by 90 o .
  • the lock described can also be designed with two sliders that are closed simultaneously.
  • the lock can be used wherever locks working with a rotary bolt are used to lock a part movable to a fixed part receiving the lock.
