Definitions
- the present invention relates to a metal locking element for metal door and window frames according to the preamble of the appended claim 1.
- Such a metal locking element is known from document DE-A-3 441 389.
- window wings are normally divided into those with conventional opening, which turn about a vertical axis which passes through the hinge supporting the wing (turn opening) and those which tilt, that is to say, with a horizontal axis of rotation and the mobile part of the window producing an opening at the top.
- Doors and windows with tilt-and-turn opening are increasingly found in this sector; however, for this purpose, both the fixed and mobile parts of the doors and windows must be equipped with a series of accessories (tie rods, rods which limit opening, twin movement handles, etc.) which allow the passage from one configuration to the other following operation of the handle.
- the locks are of great importance, for example the end bolt or flush bolt which consists of a slide (preferably metal to render it more resistant), which slides within longitudinal seats at the front of the mobile frame, positioned at the lower corner of the upright on the side opposite that with the hinge.
- the exterior of this end bolt has a locking pawl designed to engage (as the door or window is closed) with a corresponding fixed seat on the fixed frame, the base of the end bolt tapering to a point, so that when the door or window is used with the tilt function, it engages in a corresponding lower seat located on the lower crosspiece of the fixed frame, thus acting as a "second hinge" with horizontal axis.
- the end bolt is made of metal, usually cast in zamak; moreover, for correct operation, there must be the right amount of play between the bolt and its seats or sliding guides.
- conventional solutions were fitted, at the projections or support-sliding tabs, with small flexible elements in various shapes which fulfilled the triple function of guide - play compensator - silencer: this solution inevitably raised the final costs of the assembly of the various parts of the end bolt.
- the object of the present invention is to overcome the afore-mentioned disadvantages by producing a metal end bolt which requires no further working or assembly operations after its production, although functioning perfectly and practically silently.
- Figure 3 illustrates a conventional lock, represented by an end bolt la or flush bolt.
- the conventional end bolt 1a preferably consisting of a cast metal slider, has flexible elements 21a at the projections or support-sliding tabs 2a, said flexible elements fulfilling the triple function of guide - play compensator - silencer.
- the present invention which in figures 1 and 2 is represented by an end bolt 1, can be used, for example, as a rod in a tilt-and-turn system, as shown in figure 2.
- the element extends substantially longitudinally, having a series of projections which may be inserted in a corresponding seat or guide on the mobile frame of a door or window (not illustrated).
- the exterior of the lock 1 has a locking pawl 4 designed to engage (as the door or window is closed) with a corresponding fixed seat 5 on the fixed frame.
- the base of the lock 1 tapers to a point, so that when the door or window is used with the tilt function, it engages in a corresponding lower seat 6 located on the lower crosspiece of the fixed frame, thus acting as a "second hinge" with horizontal axis.
- the metallic lock extends substantially longitudinally; the lock 1 has a series of two-sided projections 2, arranged in pairs on at least one side (figure 1 shows one pair).
- the lock 1 consists of a single body and has at least one slot 3 which extends longitudinally near one edge of the lock and close to at least one pair of projections.
- the slot 3 allows a transversal flexing of the lock, so that when it is inserted in the guide, the play between the projections 2 and the guide is compensated.
- the slot 3 extends for the length L3 substantially equal to the distance L2 between the pair of projections, thus forming a leaf spring 25.
- Another projection 20 is envisaged at the centre of the slot 3, with an upper transversal projection H20 (when the lock is in its home position) greater than the corresponding transversal projection H2 of the projections 2.
- the slot 3 has a projection 22 which extends transversally, its width H22 being less than that of the transversal extension H3 of the slot 3, so that it forms an end stop for the flexing of the leaf spring 25.
Description
- The present invention relates to a metal locking element for metal door and window frames according to the preamble of the appended
claim 1. - Such a metal locking element is known from document DE-A-3 441 389.
- The description hereinafter refers to a door or window with tilt-and-turn twin opening, although the present invention may also be used on doors or windows with conventional opening which have guides for rods and similar items.
- In the metal door and window frame sector, window wings are normally divided into those with conventional opening, which turn about a vertical axis which passes through the hinge supporting the wing (turn opening) and those which tilt, that is to say, with a horizontal axis of rotation and the mobile part of the window producing an opening at the top. Doors and windows with tilt-and-turn opening, are increasingly found in this sector; however, for this purpose, both the fixed and mobile parts of the doors and windows must be equipped with a series of accessories (tie rods, rods which limit opening, twin movement handles, etc.) which allow the passage from one configuration to the other following operation of the handle.
- Amongst these components, the locks are of great importance, for example the end bolt or flush bolt which consists of a slide (preferably metal to render it more resistant), which slides within longitudinal seats at the front of the mobile frame, positioned at the lower corner of the upright on the side opposite that with the hinge. The exterior of this end bolt has a locking pawl designed to engage (as the door or window is closed) with a corresponding fixed seat on the fixed frame, the base of the end bolt tapering to a point, so that when the door or window is used with the tilt function, it engages in a corresponding lower seat located on the lower crosspiece of the fixed frame, thus acting as a "second hinge" with horizontal axis. Given that it must support considerable weights, the end bolt is made of metal, usually cast in zamak; moreover, for correct operation, there must be the right amount of play between the bolt and its seats or sliding guides. To reduce noise during the closure and movement of a wing, conventional solutions were fitted, at the projections or support-sliding tabs, with small flexible elements in various shapes which fulfilled the triple function of guide - play compensator - silencer: this solution inevitably raised the final costs of the assembly of the various parts of the end bolt.
- The object of the present invention is to overcome the afore-mentioned disadvantages by producing a metal end bolt which requires no further working or assembly operations after its production, although functioning perfectly and practically silently.
- Such an object is attained by the present invention as defined in the appended
claim 1. The invention end its advantages are further described in the detailed description below, with reference to the accompanying drawings, which illustrate an embodiment by way of example only, and in which: - figure 1 is a perspective top view of a possible embodiment of the invention disclosed;
- figure 2 is a partial schematic perspective view of a possible application of the invention disclosed;
- figure 3 is a perspective top view of a conventional end bolt.
- Figure 3 illustrates a conventional lock, represented by an end bolt la or flush bolt.
- The
conventional end bolt 1a, preferably consisting of a cast metal slider, hasflexible elements 21a at the projections or support-slidingtabs 2a, said flexible elements fulfilling the triple function of guide - play compensator - silencer. - The present invention, which in figures 1 and 2 is represented by an
end bolt 1, can be used, for example, as a rod in a tilt-and-turn system, as shown in figure 2. - The element extends substantially longitudinally, having a series of projections which may be inserted in a corresponding seat or guide on the mobile frame of a door or window (not illustrated).
- In the embodiments illustrated, the exterior of the
lock 1 has a locking pawl 4 designed to engage (as the door or window is closed) with a correspondingfixed seat 5 on the fixed frame. - The base of the
lock 1 tapers to a point, so that when the door or window is used with the tilt function, it engages in a correspondinglower seat 6 located on the lower crosspiece of the fixed frame, thus acting as a "second hinge" with horizontal axis. - As already said, the metallic lock extends substantially longitudinally; the
lock 1 has a series of two-sided projections 2, arranged in pairs on at least one side (figure 1 shows one pair). - The
lock 1 consists of a single body and has at least oneslot 3 which extends longitudinally near one edge of the lock and close to at least one pair of projections. - The
slot 3 allows a transversal flexing of the lock, so that when it is inserted in the guide, the play between theprojections 2 and the guide is compensated. - The
slot 3 extends for the length L3 substantially equal to the distance L2 between the pair of projections, thus forming aleaf spring 25. - Another
projection 20 is envisaged at the centre of theslot 3, with an upper transversal projection H20 (when the lock is in its home position) greater than the corresponding transversal projection H2 of theprojections 2. Moreover, at theadditional projection 20, theslot 3 has aprojection 22 which extends transversally, its width H22 being less than that of the transversal extension H3 of theslot 3, so that it forms an end stop for the flexing of theleaf spring 25.
