Description

The utility model relates to the field of construction, to a headset for windows, doors and other leaves, namely to hinges for hanging doors, adjustable relative to the leaves or frames, and can be used for hanging metal-plastic doors.

Known hinge for the door frame according to the patent of the Russian Federation for utility model No. 72008 (IPC: E05D 7/04, announced December 3, 2007, published March 27, 2008) containing movable and fixed half loops, each of which consists of a hinge part and plates for attaching respectively to the movable and fixed frames of the door with fasteners, a cam placed inside the cavity of the hinged part of the movable half-loop with the possibility of rotation and mutual contact, the cam stopper, a rod rigidly connected at one end to the cam and connecting the half-loops with the possibility rotation, the eccentric bushing with a collar, mounted within the cavity of the fixed part of the hinge half loop, with a fixed orientation in different angular positions, the threaded bushing, mounted under the eccentric sleeve, protective covers and inserts, closing the cavity, respectively hinged parts and fixing elements half-loops. The fist is equipped with a trench, in which, to fix its angular position, a locking screw is included, which is installed in the side wall of the hinged part of the movable half-loop.

The disadvantage of this loop is the structural complexity and low manufacturability of the cam. Using such a loop, it is impossible to eliminate large backlashes between the movable and fixed frames of the door, since the adjustment in the horizontal direction is carried out by turning the cam, and the range of adjustment values lies only within the difference of the radii of its working profiles. In addition, the door leaf clamp is adjusted by rearranging the protrusion of the eccentric sleeve into one of the grooves of the hinge part of the fixed half-loop, for which the eccentric sleeve must be removed from one groove and inserted into the other, which requires disassembling the hinge.

The objective of the claimed utility model is to develop a hinge for the door frame of a simpler and more technological design, which would provide the ability to adjust the position of the door leaf in all directions after assembling the hinge and with a wider range of regulation, that is, if there are large backlashes between the wings.

The problem is solved in that in a hinge for a door frame containing a movable and fixed half-loop, each of which consists of a hinge part and a plate for attaching, respectively, to the movable and fixed frames of the door with fasteners, a cam with a groove placed inside the cavity of the hinged part of the mobile half-loop with the possibility of rotation and mutual contact, a stopper entering the trough through an opening in the side wall of the hinged part of the movable half-loop, a rod rigidly connected at one end to the cam and rotatable half-loop, a collar with a shoulder installed inside the cavity of the hinge part of the fixed half-loop, and a threaded sleeve installed under the collar of the shoulder, the cam is equipped with a latch that includes a flat head with a gear ring meshing with teeth located on the surface of the inner cavity the hinged part of the movable half-loop installed in the end of the cam with the possibility of radial displacement to remove the teeth from engagement when the cam is rotated, and a flexible lever fixed in the groove of the cam it is attached, and the plate for attaching the movable half-loop has a housing made at the same time as the hinge part, in the guides of which there is placed with the possibility of horizontal movement a base connected to the movable frame of the door by fasteners, and a cover on which a stopper is made, interacting with the cam groove, while the latch made of flexible material, for example, from polyoxymethylene, the groove of the cam is made at an angle to its end, and the latch of the latch is fixed in the groove with its free end with the possibility of rotation of the lobe around the fastening axis of its free end.

The hinge for the door frame contains a movable and fixed half-loop, each of which consists of a hinge part 1 and 2, respectively, and a plate 3 and 4 for attaching the half-loop to the movable 5 and fixed 6 door frames, respectively, with fasteners 7. The half-loop is pivotally connected by a rod 8.

The plate 3 for attaching the movable half-loop to the movable door frame 5 comprises a housing 9, a base 10 and a cover 11 located therein. The housing 9 is integral with the hinge part 1. The base 10 is located on the guides 12 of the housing 9 and is connected to the door leaf by fasteners 7. At the base 10 there is a threaded hole in which an adjusting screw 13 is located, providing horizontal movement of the base 10 along the guides 12. The head 14 of the adjusting screw 13 is rotatably fixed in the housing 9, at the end Vki 14 made a hole (not shown) for the socket wrench, and in the case 9 made a hole 15 for accessing the socket wrench to the head 14. On the cover 11 in the area adjacent to the hinge part 1 (Fig.3), there is a stopper 16 in the form of a protrusion and a hole 17 is made in the side wall of the hinge part 1, through which the stopper 16 enters the cavity of the hinge part 1. The stopper 16 is fixed in the hole 17 with a screw 18 installed in a threaded hole made in the housing 9 tangentially to the outer cylindrical surface of the hinge part 1.

Inside the cavity of the hinge part 1 of the movable half-loop, the cam 19 is rotatably and mutually contacted, with which the rod 8 is rigidly connected.

The cam 19 has two active profiles 20 and 21 (Fig. 7) located diametrically opposite. These profiles are concentric, while the radius of the profile 20 is less than the radius of the profile 21. Profiles 20 and 21 are connected by parallel rectilinear sections. The axis of the rod 8 is offset from the axis of the cam 19 towards the profile 21 of a larger radius. On the surface of the profile 20 at an equal distance from the ends of the cam 19, a groove 22 is made (Fig. 6), with which a stopper 16 interacts through an opening 17 in the side wall of the hinge part 1 of the movable half-loop. The cam 19 is provided with a latch made of an elastic material, for example, polyoxymethylene, and containing a flat head 23 (Fig. 8) and a petal 24 located perpendicular to it. Two sides of the head 23 are parallel, and on the radial third side connecting them there is a gear ring 25, which interacts with the teeth 26 (Fig. 4), made mi in the end zone of the inner cavity of the hinge part 1 of the movable half-loop. The free end of the petal 24 has the shape of a fork, on the outer sides of the teeth of which coaxial bosses 27 are located. At the end of the cam 19, a bore 28 (FIGS. 5, 6, 7) is made for the retainer head 23 and the hole 29 for the socket wrench. On the surface of the profile 20, at an angle to the end of the cam 19, a groove 30 is selected to accommodate the petal 24 and the hole 31 for fastening its free end to the bosses 27 (Fig. 10). A through hole 32 (Fig. 9) is made in the head of the lock 23 for accessing the socket wrench to the hole 29 in the end face of the cam 19. The axis of the holes 29 and 32 are eccentric by no less than the height of the teeth of the ring gear 25.

The plate 4 (11) for attaching a fixed half-loop to the door frame 6 is made integral with the hinge part 2 of this half-loop, is located vertically, and holes are made on it for fasteners 7. The front surface of the plate 4 is made concave. On the back surface of the fixed half-loop there are two installation posts 33 perpendicular to it.

A sleeve 34 is installed in the inner cavity of the hinge part 2 of the stationary half-loop (Fig. 1, 12), under which the threaded sleeve 35 is placed. The sleeve 34 has a stepped flange 36, on which the thrust bearing 37 is located, which interacts with the entire end surface of the hinge part 1 of the mobile half-loop . The thrust bearing 37 is made of low friction self-lubricating plastic, for example polyoxymethylene. A flange 38 is made on the outer surface of the sleeve 34 below the flange 36, interacting with a groove 39 made on the inner surface of the side wall of the hinged part 2 of the fixed half-loop. At the ends of the hinge parts 1 and 2, protective and decorative caps 40 are installed (Fig. 1).

The installation of the hinge for the door frame is as follows. They put the door leaf into the frame, use special inserts to set a fold backlash, and apply a template (not shown) to the location of the hinge, by which holes are drilled for fasteners 7 of the half-loop and installation racks 33 on a fixed half-loop. The mounting posts 33 are introduced into the drilled holes and the fixed half-loop is fixed on the fixed door frame 6 with fasteners 7. A movable half-loop without a cover 11 is placed on the movable door frame 5 with the base 10 to the plane of the frame 5, the drilled holes are combined with the holes for the fasteners 7 in the base 10 and the housing 9 and fix the movable half-loop with fasteners 7, the heads of which (not shown) are recessed in the holes of the base 10. A latch is fixed on the cam 19, placing its head 23 in the bore 28 on the torus the cam 19, and the petal 24 in the groove 30. The petal 24 is fixed with the bosses 27 with the possibility of rotation around the axis of the holes 31. Insert the cam 19 with the rod 8 in the cavity of the hinge parts 1 and 2, engaging the gear ring 25 on the head 23 s teeth 26 in the cavity of the hinge part 1. Then install the cover 11 on the housing 9 of the plate 3 of the movable half loop. In this case, the stopper 16 through the hole 17 enters the groove 22 of the cam 19. The stopper 16 is rigidly fixed with the screw 16. The ends of the hinged parts 1 and 2 are closed with plugs 40.

The design of the hinge for the door frame allows you to adjust the position of the movable frame 5 of the door leaf relative to the fixed frame 6 in three directions: in the horizontal, vertical and plane perpendicular to the plane of the door leaf to adjust the clamp of the door leaf.

In the horizontal direction, the adjustment is carried out by rotating the adjusting screw head 13 with the socket wrench 13. In this case, the base 10, rigidly connected to the door leaf by the fastening elements 7, translates linearly along the guides 12 of the housing 9. The horizontal adjustment range is ± 5 mm.

In the vertical direction, the adjustment is carried out by the threaded sleeve 35. When it is rotated by means of the socket wrench, the sleeve 34 is moved vertically translationally with the flange 36 and the thrust bearing 37, on which the end face of the hinge part 1 of the movable half-loop mounted on the frame 5 of the door leaf is supported. The height adjustment range is -1 / + 5 mm.

The door leaf clamp is adjusted by turning the cam 19. For this, it is necessary to insert a socket key through the hole 32 in the head 23 into the hole 29 at the end of the cam 19. In this case, due to the presence of eccentricity between the axes of the holes 29 and 32 and the possibility of turning the petal 24 around the axis of the holes 31 into the groove 30, the flexible retainer head 23 will shift in the radial direction and the ring gear 25 will disengage from the teeth 26. The cam 19 is turned with the socket wrench to the required position, take out the key. The flexible lobe 24 returns to its original position, turning around the axis of the holes 31, and the ring gear 25 again engages with the teeth 26 on the inner surface of the hinge part 1 and fixes the cam 19 in a new angular position. The range of adjustment of the door leaf clip is ± 2 mm.

The proposed design solution for the hinge for the door frame allows you to adjust the position of the door leaf with the door closed without disassembling the hinge. The use of threaded connections for vertical and horizontal adjustment significantly expands the adjustment range. The hinge is maintenance free.
