Description

DOOR STOP WITH ROTATING SUPPORT PLATE FIELD OF THE INVENTION The present invention relates to an improved door stop to avoid opening the swing or swing stops.

BACKGROUND OF THE INVENTION Conventional devices, such as the sliding pin, the bolt lock, the door chain or the locking levers, usually only require one or two serious blows before the device fails allowing a Intruder break the lock and enter. All these devices provide a false sense of security for the occupant since the occupant believes that the device will prevent intrusion when in fact only one or two serious blows are required to break the lock. The butt contact rotary door retainers have been discovered in the reissued US Patent NO. Re 289,162. This device uses a detent bar which is rotatable in a door locking position by engagement of a projection and a slot latch. Although novel, these door seals did not attract any major commercial success as the door seals did not improve the safety of the door beyond conventional devices. The device did not have enough force to prevent an intruder from breaking the device. Improvements were made to this particular door stop and were described more fully in U.S. Patent No. 4,322,100. Various improvements were made that focused on the problem of resistance. However, these improvements did not seriously increase the resistance of the aforementioned door retainer with respect to other conventional safety devices. Recently a device has emerged on the market that is available from winner Corporation and sold under the DOORCLUB brand. Although this device exhibits improved strength characteristics in terms of supporting numerous blows before failing, the device is large, bulky and expensive and requires sophisticated equipment for installation on the floor in front of the door. This installation requirement and size affects the product's marketability. SUMMARY OF THE INVENTION The disadvantages of the prior art can be solved by providing a stopper for rotating contact door butt to be in register both with a frame and with the door when rotating a single lever. According to one aspect of the invention, the detent for the butt contact rotary door has an installable mounting plate on a door frame, a retainer member installed in a rotatable and slidable manner on the mounting plate, a means of push to push the retainer member into the decoupled position, a lever installed rotatably on the mounting plate, a latch or fastener installed on a door, the door is hinged inside the door frame. The detent means is rotatable between an open position of the door and a locking position of the door and slidable between an uncoupled and coupled position. The lever rotates in relation to the detent member between a locking state and an unlocking state. The lever has a cam for pushing the detent member against the pushing means and the engaged state when the lever rotates between the locking and unlocking states. When the lever rotates between the locking and unlocking states, the retainer member couples and uncouples the mounting plate and the knocker to lock and unlock the door in the door frame.

DESCRIPTION OF THE INVENTION The retainer for the butt contact rotary door 10 of the present invention is generally illustrated in FIG. 1. The door retainer 10 is used with a conventional door unit comprising a door 12 installed inside the door. frame 14 using the hinges 16. The door 12 also has a door knob 18. Referring to Figures 2-5, the door retainer 10 usually comprises a base plate 20, a center pivot or hinge 22, a lever 24, a retainer member 26, and a torsion spring 28 (figure 5) .The mounting plate 20 has an upper tab 30 and a lower tab 32 which are integral with the base plate 20 and extend from Each end of the upper lug 30 and the lower lug 32 are wound towards the rear on themselves defining the projections 34, 36. The projections 34 and 36 define a cylindrical cylindrical channel through which it is The center pivot 22 extends. In the region of the weld / upper tab 30 and lower tab 32 both have an emboss 38 embossed thereon to improve the strength thereof. The upper edge of the lower lug 32 is provided with a projection 40. The lever 25 has an arm 42 extending from a cylindrical core 44. The cylindrical core 44 has a central bore extending in the axial direction by adapting the lever 24 to install it as a pivot on the center pivot. The central cylindrical core 44 has an eccentric surface 46 (FIG. 8) to extend the effective axial length of the cylindrical core 44. The retainer member 26 has a cylindrical core 48 and an abutment arm 50 extending therefrom. The lower surface of the arm so that the butt contact 50 has two slits in it. The projection groove 52 extends radially from the center of rotation and is positioned in the coupling projection 40 when the detent for the rotating stop contact door 10 is in a locking position for the door (Figure 1). The slit of the door 56 extends in the direction substantially perpendicular to the slit of the projection 52. The slit of the door 56 will engage with the knocker 58 when the detent for the swiveling door of butt contact is in the locked position (Figures 3 and 8). The upper surface of the cylindrical core 48 is bent to be complementary to the eccentric surface 46 of the lever 24. The cylindrical core 48 has a recessed hole 60 adapted to receive the torsion spring 28. Optionally, the upper surface of the cylindrical core 48 of the retainer member 26 has a detent for receiving the leading edge of the eccentric surface 46 of the lever 24 when it is in the fully locked position. The knocker 58 consists of a pair of abutments of the base 62 and 64 and the plate of the knocker 66 extends through them. The abutments of the base 62 and 64 are provided with holes 68 for receiving the screws 70 or other means of suggestion to be installed on the door 12. Once installed the plate of the knocker 66 is separated from the flat surface of the door 12 ( figure) . The door retainer 10 is installed in alignment with the lever 24 and the retainer member 26 in a complementary fit. The spring 28 is presented in the reamed hole 60 and is compressed by the placement between the projections 34 and 36. The central pivot 22 extends through the projection 34, the lever 24, the retainer member 26, the spring 28 and the projection 36. The central pivot 22 is permanently locked within the projections 34 and 36 in any of the well known ways. The lever 24 is installed rotatably about the central pivot 22 between a locked and unlocked state (FIGS. 2 and 3, respectively). The spring 28 urges the retainer member 26 to engage the lever 24 in a complementary fit. The retainer member 26 is also installed in the form of a pivot to rotate about the central pivot 22. However, the spacer between the projections 34 and 36 allows the sliding movement of the retainer member 26 along central pivot 22 between a coupled and uncoupled position.

When the lever 24 and the retainer member 26 are adjusted in a complementary manner together the lever 24 and the retainer member 26 rotate about the central pivot 22 as a single unit between an open door position (Figure 4) to a locked position of the door (figure 2). When the slit of the projection 52 is elongated so as to extend over the projection 40, and the lever 24 is rotated in relation to the retainer member 26 between an unlocked state and a locked state, the eccentric surface 46 will push the retainer member 26. down so that the slit of the projection 52 engages the projection 40. By counter rotating the lever 24 in relation to the retainer member 26, the spring 28 pushes the retainer member 26 to decouple it from the projection 40 allowing the free rotation of the retainer member and lever 24. To install the door retainer 10 of the present invention, a recess corresponding to the general configuration of the base plate is made or a chisel is made in the frame of the door 14 The screws 70 are inserted through the holes 72 to install the mounting plate 20 in the door frame. It should be noted that the projections 34 and 36 are directed out of the door 12 so as not to interfere with their oscillation. The knocker 58 is installed in the door immediately adjacent to the door retainer 10. The upper edge of the door knocker plate 66 should be flush with the projection 40. Obviously, the door retainer can be installed on doors facing the door. the left side or towards the right side by simply inserting the door catch 10. During use, the occupant closes the door 12. The lever 24 and the stop member 26 are rotated in unison in the locking position of the door of the door. so that the slit of the projection 52 is aligned with the projection 40 and the slit of the door 56 is aligned with the plate of the knocker 66. In this position »the retainer member 26 is in the swing path of the door 12. The retainer member 26 is held in place while the lever 24 is rotated relative to it by moving from the unlocked state to the locked state. As the lever 24 rotates relative to the retainer member 26, the eccentric surface 46 pushes the retainer member 26 downward to engage the projection 40 and the knocker plate 66. The lever 24 is rotated until it contacts the the frame of the door 14. In this blocking position / the door 12 and the frame of the door 14 are completely integrated. To unlock, the lever 24 is rotated in the opposite direction relative to the retainer member 26 until the lever 24 and the retainer member 26 are aligned allowing the retainer member 26 to be urged upwardly by the spring 28 for uncoupling it from the projection 40 and from the latch plate 66. Once decoupled, the lever 24 and the retainer member 26 are free to rotate from the locked position of the door to the open position of the fourth outside the swinging the door 12. Preferably, the mounting plate 20 is fabricated from a cold-rolled, die-cut stainless steel sheet. The lever 24 and the retainer member 26 are preferably melted under pressure. However, it should be noted that the retainer member 26 is not hollow as in the previous devices. The tests carried out on various models of detent for revolving door of butt contact illustrates the evident deficiencies in all the previous models. The door catch, according to the Republican US Patent No. Re 29,162, is deformed and uncoupled at the first stroke of 33 ft./lbs., Providing a minimum amount of security. An intruder could easily break this catch for the door and enter. The door stop, in accordance with US Patent No. 4,322,100, was found deformed in its writing with the second stroke of 33 ft / lb, and uncoupled in the seventh stroke. Although an improvement in the sugestion capacity, the level of security was not superior to other blocking devices in the market. The retainer for the door 10 of the present invention was observed to support 50 strokes of 33 ft / lb, without deformation. The retainer for the door 10 also achieved the top level for the standard test, ie, ASTM grade 40 the retainer for the door 10 did not uncouple and continued to hold even after the solid wooden door broke. Now, it is evident to a person skilled in the art that the detent for the rotating door in abutting contact of the present invention can be easily modified. It should be understood that certain changes in the components can be effective without departing from the spirit of the invention and within the scope of the appended claims.
