Definitions

  • the present invention relates to a door stop assembly.
  • the invention in particular relates to a strike plate comprising the door assembly.
  • Door stop assemblies In order to dampen the mechanical impact of a closing door, it is known in the prior art to provide door stop assemblies.
  • Door stop assemblies generally comprise a plate which is provided with a bumper strip for dampening the impact of the closing door, wherein the plate is attached to the door enclosure, such as a frame or a pole, at a position where the closing door would hit the door stop assembly at a high speed. This position is generally at the side of the door enclosure where the strike plate of the door is provided.
  • the strike plate of a door assembly is the element of the door assembly that receives a latch and/or dead bolt when locking and/or latching a door.
  • Such door stop assemblies are known to dampen the impact of sliding doors, such as described in patent publication JP6068786 , or of rotating doors, such as described in patent publication EP3239440 .
  • the patent publication EP3239440 in particular discloses a strike plate comprising an "L"-shaped profile, wherein one of the legs of the "L"-shaped profile comprises the door stop assembly.
  • the door stop assembly disclosed in patent publication EP3239440 comprises a plate having opposing major surfaces interconnected by a plate sidewall, i.e. one of the two legs of the "L"-shaped profile forms said plate.
  • the plate is provided with an elongated rectilinear channel delimited by opposing channel sidewalls extending in an elongation direction between two opposing openings in the sidewall of the plate, also referred to as end openings.
  • the channel forms a further opening, also referred to as bumper opening, in one of the major surfaces of the plate i.e.
  • the door stop assembly comprises a bumper strip inserted in the channel and protruding from the channel through the bumper opening such as to come in contact with the closing door prior to the closing door impacting on the plate itself thereby optimally absorbing the impact of the closing door.
  • the bumper strip tends to shrink, which causes the bumper strip to slide out of the channel along one of the end openings in the channel, in particular due to the mechanical vibrations caused by the impact of the closing door.
  • a door stop assembly arranged for damping the mechanical impact of a closing door wherein the problem of the prior art is solved.
  • the present invention solves this aim by providing a door stop assembly comprising a plate having opposing major surfaces interconnected by a plate sidewall.
  • the plate is provided with an elongated, preferably rectilinear, channel delimited by opposing channel sidewalls extending in an elongation direction up to a first opening in the sidewall of the plate.
  • the openings of the channel in the sidewall of the plate are also referred to as an end openings.
  • the channel forms a second opening in one of the major surfaces of the plate, i.e.
  • the door stop assembly further comprises a bumper strip inserted in the channel through the first opening and protruding from the channel through the second opening i.e. such as to come in contact with the closing door prior to the closing door impacting on the plate itself thereby optimally absorbing the impact of the closing door.
  • the door stop assembly of the present invention further comprises an occluding device for maintaining the bumper strip in the channel by hindering the passage of the bumper strip through the first opening back out of the channel.
  • the occluding device comprises an insertion part configured to be inserted into the channel through the first opening of the channel, wherein the insertion part comprises a main body extending in a length direction, in use parallel to the elongation direction of the channel, from a bumper end configured to lie adjacent to the bumper strip in the channel, up to a head end configured to lie adjacent to the first opening of the channel.
  • the insertion part further comprises fixation means provided on the main body. The fixation means are arranged to fixate the position of the occluding device in the channel after insertion of the occluding device in the channel.
  • the bumper strip is no longer able to slip out of the channel through the first opening in the channel, even if the bumper strip substantially shrinks due to cold temperatures and even if the bumper strip is agitated by the mechanical vibrations of the impacting closing door.
  • the present invention has the further advantage that the bumper strip is maintained in the channel without degrading the aesthetics or quality of the door stop assembly.
  • the bumper strip is in particular not secured in the channel by means of an adhesive the presence of which would not only be visually unpleasant for the user, but would also make the quality of the door stop assembly prone to deterioration in function of time and environmental influences.
  • the bumper strip is in particular also not secured in the channel by pinching the plate such as to deform a part of the channel into an occlusion of the channel. Said pinching would after all damage the plate, which damage would be particularly visible when the plate which is pinched has been coated such as powder coated.
  • the present invention has the further advantage that the width of the channel i.e. the dimension between the two channel sidewalls, can be increased without risking that the bumper strip slips out of the channel through the first opening.
  • This has the advantage that the bumper strip can more easily be inserted into the channel, i.e. that the bumper strip can be pulled into the channel through one of the end openings with a smaller amount of force.
  • This is particularly advantageous when the plate is coated, for example powder coated.
  • the width of the channel is respectively decreased or increased.
  • the amount of coating of the plate had to be reduced in order to enable the insertion of the bumper strip inside of the channel.
  • the present invention has the further advantage that the variation of the length of the bumper strip, which for example occurs due to the inexact cutting of the bumper strip or due to the shrinking of the bumper strip at cold temperatures, is not visible.
  • the occluding element abuts on the ends of the bumper strip, thereby compacting the bumper strip to a more reduced length i.e. slightly longer bumper strips are shortened more than slightly shorter bumper strips up to the same reduced length of the bumper strip.
  • a slightly oversized bumper strip can be used with respect to the available length in the channel in the elongation direction i.e.
  • the available length being the length of the channel in the elongation direction minus the lengths of the inserted occluding devices.
  • the cut ends of the bumper strip which tend to be non-straight due to the inexact cutting of the bumper strips, are flattened upon abutment with the occluding device, thereby increasing the aesthetics of the device.
  • the present invention has the further advantage that, because of the compaction of the bumper strip by the occluding device, the inside of the channel cannot be accessed by a user. This alleviates the risk of vandalism, wherein a vandal would grab the bumper strip from within the channel such as to rip the bumper strip out of the channel for example through the bumper opening.
  • the term door not only refers to a conventional door provided in an opening of a wall, but also to other similar applications such as to a gate provided in the opening in a fence, or to a window provided in the opening of a wall etc.
  • the door enclosure would be a frame in case the door is a conventional door or a window, and would be a pole or another support such as a wall in case the door is a fence/gate.

  • the fixation groove 29 has a constant width w6 i.e.
  • the fixation groove 29 width w6 is dimensioned such that the barb 27 is moveable within the fixation groove 29 between a retracted state and a deployed state.
  • the apex 30 of the barb 27 acts as a rotation point around which the two legs 32a, 32b of the V-shaped barb 27 rotate in and out of alignment with the length direction LL3.
  • the legs 32a, 32b of the barb 27 are less aligned along the length direction LL3 than in the retracted state i.e. the sharp angle ⁇ between the legs 32a, 32b of the barb and the length direction LL3 is smaller in the retracted state than in the deployed state.
  • the fixation means 9 and the channel 18 are dimensioned such that in the deployed state, the lateral dimension of the insertion part 4 i.e. the dimension of the insertion part along the width direction WW18 of the channel 18, is larger than the width w4 of channel 18.
  • the fixation groove width w6 is larger than the barb width w5.
  • the barb 27 on its own is biased towards the deployed state i.e. the barb 27 itself in isolation the remaining components of the insertion part 4 is biased to move out of the retracted position towards the deployed state.
  • FIG. 7 shows two cross-sections of the strike plate 2 from figures 1-4 in a plane perpendicular to the elongation direction LL18 at position AA and at position BB as indicated in figure 6 These cross-sections clearly demonstrate how the protrusion 33 and the flange 7 do not extend further in the thickness direction TT18 than the bumper strip 22 , such as to avoid that the closing door impacts on the insertion part prior to impacting on the bumper strip 22.
  • the maximum width w1 of the main body 6 is larger than the width w2 of the bumper opening 21 such as to avoid that the occluding device 1 is pulled out of the channel 18 in a direction perpendicular to the elongation direction, i.e. along the thickness direction TT18.
