Definitions

  • the invention relates to a fastening part for fastening a End plate on the lock housing of mortise locks in the preamble of Claim 1 mentioned type.
  • the lock housing is formed by two side plates, which, after they have been coupled together, with the faceplate or the faceplate of the lock via a pair of fasteners, the facilities to their Have connection with the side plates, and by a fastening screw connected, which are inserted through the front plate of the castle becomes.
  • the fasteners currently used in this area are manufactured by costly mechanical and casting processes.
  • One in that regard known configuration consists of a type of solid block attached to two opposite sides has respective projections, which in corresponding Slots are used in the side panels of the lock case are provided.
  • this massive part a threaded hole for a screw through a cover of a Front side of the castle is arranged through, which for a particular case selected construction, finishing and color.
  • the invention has for its object a fastening part of the beginning to create the type mentioned, with simple manufacture, an improved assembly the front plate or the cuff on the housing of the lock.
  • the fastening part according to the invention has a sheet metal construction, which is created by stamping and embossing, this fastening part at Assumption of the front plate of the lock as a front reference and with regard to it vertical working position in a lock has a front base part, the is parallel to the face of the castle, and that starting from the horizontal upper and lower edges of this front base part towards the rear a pair of converging oblique turns and a pair of horizontal shafts forms that abut each other and are identical to each other, this front Base part a hole for the screw and a little smaller width than that Has interior of the lock housing, while the oblique bends Have width that is equal to that of the front base part.
  • the shafts have one Width, which is equal to that of the interior of the lock housing, and form between there is a longitudinal frusto-conical opening that faces towards the rear converges, and together they form hooks on the side edges that lead to the Face plate of the lock are directed.
  • the frustoconical opening is with the Hole aligned, and the hooks have a length that is slightly less than is the horizontal dimension of respective slots that are in the side plates of the Lock housing are available.
  • the two hooks on the same side edge of the abutting shafts have an overall thickness that is slightly less than is the vertical dimension of the slots.
  • the fastening parts according to the prior art has the inventive Fastener has a number of properties that serve to provide a flawlessly adjusted and reliable assembly even in the case of blows and Allow vibrations that are inherent in normal use of the castle. Below are these new beneficial ones Properties described.
  • the oblique walls of the hook hit onto the front edge of the slots and pull the side panels of the Lock housing against both the face plate of the lock and against that Fastening part, that is towards the opposite side plate.
  • the sloping shape of the walls enables the compensation of a game and of Design tolerances so that the lock housing has a stiffness and Preserves dimensional stability.
  • the good fit which is characterized by this, also contributes to this Tension between the side plates and the longitudinal edges of the shafts results. This good fit is supported by the gradation in reducing the width, which results in the oblique bends in front of the hook.
  • the slightly smaller dimension of the diameter of the opening causes which is formed between the abutting shafts that when Screwing the screw these shanks apart from each other in the manner of a Separate expansion anchors, causing these hooks against the longitudinal edges of the slots be pressed and the assembly of the side plates of the Stiffen the lock housing opposite the fastening part.
  • Figure 1 is a perspective exploded view of a Fastening part (3) according to the invention, which in a side plate (1a) of the Lock housing is installed, the other side plate (1a), the end plate (2) of the lock (2) and the self-tapping screw (4) in their respective Assembly positions are shown.
  • Figure 2 is a perspective view of the fastener (3), however when viewed from behind.
  • FIG. 3 is a vertical front view of the front base part (5) the fastening part (3).
  • FIG. 4 is a bottom view corresponding to FIG. 3.
  • FIG. 5 is a section along the line V-V in FIG. 4.
  • FIG. 6 is an enlargement of that surrounded by a circle in FIG. 4 Detail IV
  • Figure 7 is a cross section of the lock (1-2), its fastening part (3) used, but not yet pressed, the self-tapping Screw (4) for insertion through the front plate (2) of the lock is arranged.
  • FIG. 8 is an enlargement of detail VIII, which is shown in FIG Circle is surrounded.
  • Figure 9 is section IX-IX, which is given in Figure 8.
  • Figure 10 is a representation similar to Figure 7, but the final attachment shows.
  • FIG. 11 is an enlargement of detail XI, which is shown in FIG is surrounded by a circle.
  • Figure 12 is a view from the right side of Figure 10, the is enlarged and is compared to Figure 11.
  • This fastening part (3) has the special feature that it is a Has sheet metal construction, is formed by stamping and embossing, the Fastening part starting from the front plate (2) of the lock as the front Regarding and in terms of its working position in a vertical lock (1-2) one has front base part (5) which is parallel to the end plate (2) of the lock, starting from the upper and lower horizontal edges of this front Base part (5) of the fastening part (3) towards the rear a pair of converging oblique bends (6) and a pair of horizontal shafts (7) forms the abut each other and are equal to each other.
  • This front base part (5) has a hole (5a) for the self-tapping screw (4) and a width on the is slightly smaller than the inside of the lock housing (1), the oblique Bends (6) have a width which is equal to the front base part (5), while the shafts (7) have a width that is equal to the inside of the Lock housing (1) and between them a longitudinal frustoconical Form an opening that converges towards the rear.
  • the stems form along their Side edges of the respective hooks (9) directed towards the end plate (2) of the lock are.
  • the frustoconical opening (8) is with the bore (5a) of the front Base part (5) aligned and has a diameter that is slightly smaller than the tip of the self-tapping screw (4).
  • the hooks (9) have one Length which is slightly smaller than the horizontal dimension of respective slots (10), which are present in the side plates (1a) of the lock housing (1).
  • the Form hooks (9) of the same side edge of the abutting shafts (7) an overall thickness slightly smaller than the vertical dimension of the slots (10) is.
  • the hooks (9) form an inclined wall (11) from the front converges towards the rear of the barrel (7) itself and at the mouth and on the floor this hook (9) forms respective operating dimensions that are larger or smaller than are the wall thickness of the side plates (1a) of the lock housing.
  • the operation of the fastening part (3) is clear from Figures 7 to 12 and the figure 1 itself recognizable.
  • the fastening part (3) is very simple mounted that the hooks (9) are inserted through the slots (10), such as this is shown in Figures (7) to (9).
  • the end plate (2) of the Lock is created and through this the self-tapping screw (4) used, which exerts a tensile force on the fastening part (3) through which this is pulled against this end plate (2) of the lock until it fits into the Figures (10 to 12) shown mounting position reached in the sloping walls (11) the hook (9) the side plates (1a) against the end plate (2) ( Figure 15) and have pulled against the longitudinal edges of the shafts (7) of the fastening part (3).
  • the shafts are pushed apart so that the hooks (FIG. 12) (9) are pressed laterally against the longitudinal edges of the slots (10).
