Definitions

  • the invention relates to a locking device, particularly a hold-open device, for a door actuator assembly including a guide rail and a slide arm.
  • Door actuator assemblies with guide rails mounted to doorframes may use locking devices mounted to the guide rails for holding-open a door leaf at a desired position.
  • a plurality of those locking devices is known from the prior art, for example from EP 2 672 046 A2 , EP 1 544 394 A2 , and EP 2 169 160 B1 .
  • EP 2 672 046 A2 discloses an arrangement having a guide rail.
  • a moving element is provided with a first detent.
  • the detent is firmly connected with the moving element.
  • the guide rail is provided with a hold-open portion.
  • a second detent is rotatably mounted about an axis of rotation. The detents are separated from each other. The axis of rotation of the second detent is arranged parallel to a mounting surface.
  • EP 1544 394 A2 discloses a device including a drive and slide arm with a slider guided in a slide rail.
  • a spring-tensioned stop element is mounted on a pivotal lever which is assigned an overload security device with an overload spring acting on the overload element, which can be connected through force engagement with the stop element.
  • EP 2 169 160 B1 discloses a device having a door closer connected with a sliding arm.
  • a slider is arranged at the sliding arm and guided in a sliding rail.
  • a locking element is arranged at the slider. The locking element combines together with a locking extension for fixing the slider and for locking a door leaf.
  • a locking lever is pivotably mounted at carriages in a rotary bearing on one end.
  • An elastomeric element is arranged in the locking lever, retains force of the locking device and damps a movement of the door leaf.
  • Conventional locking devices may suffer from bad performance quality and poor durability. Furthermore, conventional locking devices may tend to be very loud during operation, which may be experienced as a negative quality feature by a user.
  • a problem to be solved by the present disclosure is to provide an alternative or improved locking device for a door actuator assembly.
  • the locking device has improved engagement features for reducing an impact and/or noise during engagement.
  • the locking device is particularly configured as a hold-open device.
  • the locking device is suitable for a door actuator assembly with a guide rail and a slide arm.
  • the locking device comprises a stopper for securing at the guide rail.
  • the stopper includes an engagement portion.
  • the locking device comprises a movement member, particularly a slider, for being movably guided by the guide rail to guide the slide arm along the guide rail.
  • the movement member includes an engagement wire spring configured to engage with the engagement portion of the stopper for holding the movement member.
  • the locking device has a very low engagement or impact sound, because the area of impact between the engagement wire spring and the engagement portion is reduced due to a (thin) wire of the engagement wire spring.
  • the engagement portion and the engagement wire spring form a releasable snap-in connection between the stopper and the movement member.
  • the engagement portion has a spearhead-shape with a blunt end or a pointed end, and/or a dart flight-shape with a blunt end or a pointed end.
  • the spearhead-shape or dart flight-shape enables the engagement spring to snap into or hook onto a neck of the engagement portion adjacent to the spearhead-shape or the dart flight-shape.
  • the engagement portion includes a constriction section and a tip end section, wherein, particularly, the constriction section and the tip end section smoothly transition into each other.
  • the engagement wire spring can snap into or hook onto the constriction section after having passed the tip end section for engaging the movement member and the stopper to hold open the door leaf.
  • the constriction section tapers in a direction (for example, an axial direction) away from the tip end section with a taper angle within a range between 45° and 85°. Additionally or alternatively, the tip end section tapers in a direction (for example, an axial direction) away from the constriction section with a taper angle within a range between 100° and 130°. It has been found, that those taper angles values result in a particularly low engagement sound between the stopper and the movement member.
  • the engagement wire spring is configured to engage the engagement portion by encompassing the engagement portion on two sides of the engagement portion, particularly two oppositely directed sides of the engagement portion. Thereby, a retaining force of the engagement wire spring can be shared by two sections of the engagement wire spring.

Additionally or alternatively, the first u-shaped wire section and the second u-shaped wire section are connected to each other at respective ends of the first and second u-shaped wire sections, particularly to form a closed wire spring.
  • the engagement wire spring is fastened at the respective ends, for example by a locking screw, in a reception of the movement member.
  • the engagement wire spring may extend out of the reception in an axial direction to the stopper.
  • the movement member further comprises at least one biasing element, particularly at least one pin, arranged in a reception of the movement member for biasing the first u-shaped wire section and the second u-shaped wire section in a direction to each other.
  • the tip end section is configured to push the first u-shaped wire section and the second u-shaped wire section apart from each other during engaging the engagement wire spring and the engagement portion. Additionally or alternatively, the first u-shaped wire section and the second u-shaped wire section are configured to snap into the constriction section when having passed the tip end section during engaging of the engagement wire spring and the engagement portion.
  • the locking device further comprises a dampening element, for example made of an elastic or compressible material.
  • the dampening element is arranged to dampen an impact of the movement member onto the stopper.
  • the dampening element is provided separate from the engagement wire spring for separating the dampening feature and the engagement feature from each other.
  • the dampening element can dampen strong impacts, whereas the engagement wire spring may have a filigree structure to reduce an engagement noise.
