Definitions

  • the present invention relates to a lock for a door structure comprising a frame arranged to be secured against a first side of a tubular member of said door structure; at least one bolt which is slidably mounted on the frame between a retracted and a projecting position and which extends in its projecting position, when the frame is mounted against the said first side of the tubular member, through a first opening provided in this first side and through a second opening provided in a second side of the tubular member situated opposite to said first side; an actuation mechanism arranged to move said bolt from its retracted to its projecting position and vice versa and means for securing the lock against the tubular member comprising a screw threaded tubular element having a diameter larger than that of said first opening but smaller than that of said second opening, which tubular element is arranged to be slid over said bolt through said second opening into the tubular member and to be fixed by screwing to the frame in order to secure the lock against the first side of the tubular member.
  • the lock according to this document comprises two bolts, namely a dead bolt and a latch bolt. Both bolts are associated with securing means comprising a tubular element showing a first end portion provided with an external screw thread. The diameter of this end is smaller than that of the first opening in the first side of the tubular upright member of the door structure against which the lock is to be secured.
  • the tubular element further shows a second portion having an external diameter larger than that of the first opening but smaller than the diameter of the second opening so that it can pass through the second opening but not through the first one.
  • the tubular element is slid over the bolt of the lock through the second opening into the tubular upright member until the first portion of the tubular element projects on the other side out of the tubular upright member.
  • the first portion of the tubular element is then screwed into the frame of the lock in order to secure the lock against the tubular upright member. Since two bolts are comprised in the lock according to EP 606 196, the lock is secured against said tubular upright member at two different locations thanks to two securing means.
  • the tubular element will extend into the lock over a distance depending on the thickness of the wall of the first side of the tubular upright member.
  • the externally screw threaded portion of the tubular element has such a length that it can be used for large and small wall thickness of the upright tubular member.
  • the externally screw threaded portion of the tubular element will extend over a distance into the lock which is greater than the distance required for a good securing of said lock on the upright tubular member.
  • the required free space has however to be provided within the lock. This will thus influence the dimensions of the lock, so that in certain circumstances the lock cannot be mounted between two upright members of the door structure.
  • the externally screw threaded tubular elements are relatively expensive to manufacture. Indeed, they need to present the global shape of a tubular bolt having an elongated screw threaded portion forming the body of the element and a portion forming the head of the element. This head portion must have a diameter larger than the diameter of the first opening in the tubular member in order to abut this tubular member when securing the lock. In view of the required wall thickness of the tubular securing element, this element has to be milled out of massive metal. Since not only the screw thread but also the hole has to be milled, this can be an expensive process.
  • the present invention is aimed at solving the aforementioned problems.
  • a lock according to the invention is characterised in that said screw threaded tubular element is internally screw threaded and the securing means further comprise an externally screw threaded tubular element which is a protruding part of said frame and which provides a passage through which said bolt projects out of the frame, which externally screw threaded element is arranged to project through said first opening into said tubular member and to cooperate by screwing with said internally screw threaded element to secure the lock against said first side of said tubular member.
  • said externally screw threaded tubular element is part of the frame and projects through the first opening of the tubular member to cooperate by screwing with the internally screw threaded tubular element to secure the lock against said tubular member, no unnecessary free space has to be provided within the lock to accommodate the externally screw threaded securing element when the lock is secured against a tubular member having a reduced wall thickness. Therefore, the dimensions of the said lock can be maintained as reduced as possible.
  • the externally threaded tubular securing element can now be easily made from tube metal, its length can be increased without a substantial increase of its manufacturing costs so that a better or longer guidance can be provided for the bolt.
  • the frame of the lock comprises a cover plate having at least one internally screw threaded opening in which said externally screw threaded tubular element is screwed.
  • the externally screw threaded tubular element has a peripheral collar arranged for abutting said cover plate when the externally screw threaded tubular element is screwed in said internally screw threaded opening.
  • the collar is easy obtained from a metal tubular element which is externally screw threaded from both of its ends leaving between the obtained two screw threaded end portions a non screw threaded portion of the tubular element, which portion constitutes the collar.
  • This collar enables an easy mounting of the externally screw threaded tubular element since this element will automatically be screwed to the correct position.
  • the frame of the lock further comprises a base plate to which the cover plate is secured and that said peripheral collar is blocked between said base plate and said cover plate.
  • the externally screw threaded tubular element can neither be screwed in one direction nor in the opposite direction in said cover plate. Said tubular element will thus be maintained in its place both when screwing the internally screw threaded securing element onto the externally screw threaded element and when unscrewing it.
  • the internally screw threaded tubular element is provided at one end with at least one engagement means for a screwing device.
  • the lock comprises a second bolt and the securing means comprise a second externally screw threaded tubular element which is a further protruding part of the frame and which provides a further passage through which said second bolt projects out of the frame and a second internally screw threaded tubular element cooperating by screwing with said second externally screw threaded element to secure the lock against said first side of the tubular member.
  • FIG. 1 Illustrated in figure 1 is a lock according to the invention in its secured position against a tubular member 13 of a door structure such as a gate.
  • the lock comprises a frame 1 which comprises a housing 2 and a cover plate 8 fastened on the housing 2 by means of a screw 14, the peripheral edge of the cover plate 8 abutting the housing 2.
  • the lock further comprises two bolts 12a and 12b, namely a dead bolt and a latch bolt which are slidably mounted on the frame between a retracted and a projecting position. In their projecting position, they extend through first openings 17 provided in a first side 13a of the tubular member 13 of the door structure and through second openings 16 provided in a second side 13b of the tubular member 13 situated opposite to the first side.
  • the lock further comprises securing means comprising externally screw threaded tubular elements 4 and internally screw threaded tubular elements 5 which are arranged to be slid over the bolts 12a and 12b. These elements 4,5 cooperate with one another for securing the lock onto the first side 13a of the tubular member 13.
  • the cover plate 8 shows openings 10 for the passage of the externally screw threaded tubular elements 4.
  • the openings 10 in the cover plate 8 are internally screw threaded so that the externally screw threaded tubular elements 4 can be screwed into these openings until they form a protruding part of the frame.
  • they could also be fixed in another way to the frame, for example by welding.
  • the externally screw threaded tubular elements 4 project through the first openings 17 provided therefore in a first side 13a of the hollowed tubular member 13.
  • Corresponding second openings 16 which faces the first openings 17 are provided in a second side 13b of the tubular member 13 opposite to the first side 13a.
  • the diameter of the first openings 17 is chosen to be smaller than the outer diameter of the internally screw threaded tubular elements 5 whilst the diameter of the second openings 16 is chosen to be larger than this outer diameter so that the externally screw threaded securing elements can pass through the seconf but not through the first openings.
  • the internally screw threaded tubular elements 5 can be slid over the bolts 12a and 12b through the openings 16 into tubular member 13 and can then be screwed onto the externally screw threaded tubular elements 4 until they abut the internal face of the first side 13a of the tubular member 13. In this way, the lock is firmly secured to the member 13.
  • the relatively large area of engagement between the internally screw threaded tubular elements 5 and an externally screw threaded tubular elements 4 increases the reliability of the securing of the lock against the tubular member 13.
  • the internally screw threaded tubular elements 5 are provided at their extremities with engagement means such as notches 7 for tightening these tubular elements 5 onto the tubular elements 4 by using an appropriate ring or box spanner 15.
  • the spanner 15 has a length which is substantially greater than the section of the tubular member 13 so as to allow the spanner to be worked from the outside.
  • the diameter of the spanner 15 corresponds substantially to the diameter of the periphery of the extremities of the internally screw threaded elements 5.
  • the spanner 15 has projections 15a intended to interact with notches 7.
  • notches 7 are provided in the internally screw threaded tubular elements 5.
  • two diametrically opposed notches are provided, each having a rectangular profile.
  • FIG. 2 Illustrated in figure 2 is the aforementioned lock according to the invention, further comprising a base plate 3 and an actuation mechanism whose components are generally designated by reference number 11.
  • Bolts 12 are composite bolts.
  • a member 3a of the base plate 3 facing the cover plate 8 presents openings 9 coaxially disposed with the openings 10 in the cover plate 8 for the passage of the externally screw threaded tubular elements 4.
  • Each externally screw threaded tubular element 4 is provided with a peripheral collar 6 having an external diameter larger than the diameter of the openings 9 in the base plate 3 and the diameter of the openings 10 in the cover plate 8 so as to abut both the base plate 3 and cover plate 8.
  • the collars 6 can be arranged at a distance from an extremity of each externally screw threaded tubular element 4 substantially corresponding to the thickness of the member 3a of the base plate 3 in which the openings 9 are provided. Consequently, the tubular element 4 does not penetrate within the housing 2 of the lock and thus doesn't occupy space therein.
  • the cover plate 8 is arranged to be fastened by means of a screw 14 to the housing 2. In this way, the collars 6 are blocked between the base plate 3 and the cover plate 8 when this cover plate is fastened on the housing 2 of the lock.
  • FIG. 3 Illustrated in figure 3 is the aforementioned lock according to the invention shown in its assembled state
