Description

The invention relates to a loop intended, in particular, for heavier movable blocks that have more weight than ordinary ones.

The hinges used for mounted outdoor movable units must meet special safety requirements and be different from the hinges used traditionally.

Distinctive features of such loops are as follows:

1. - The screws used to fasten the hinges must be closed with special plates (most of the known constructions designed for outdoor moving blocks satisfy these requirements);

2. - It is necessary to provide precise adjustment to better fit the position of the movable unit relative to the fixed frame (this requirement is complicated by irrational technological solutions);

3. - Safety must be ensured, which excludes unauthorized removal of the movable unit from the hinges without violating the integrity of the hinge parts and without first disassembling the hinge with a special tool when the movable unit is open (this requirement is not found in the prior art for adjustable loops on three axes).

The following directions can be an example of fine adjustment of a moving unit. Adjustments affecting the movable block are carried out in three axes:

- along the axis parallel to the plane of the moving block (X axis);

- along the axis perpendicular to the plane of the moving block (Y axis, preload);

- along the vertical axis (axis of rotation Z).

Known hinge for opening a door or window frame, described in patent RU 2183717. The hinge for opening a door or window frame contains the first and second hinge parts connected by a rod. The device makes it possible to independently adjust between the first and second hinged parts parallel and perpendicular to the common plane of the door or window. The adjustment along the X axis is performed by a cam made integrally with the rod and mounted to rotate inside the cavity of the upper hinge part, the cam and the cavity of the hinge part having mutual contact surfaces made in such a way that turning the cam causes relative translational movement between the hinge parts in parallel the common plane of the door and the doorway, and between the cam and the plane of the upper hinge part, regardless of their relative angular position, there exists yney least two axial areas of contact are mutually opposite to each other relative to the rod. The disadvantage of this loop design is the complex shape of the inner cavity of the hinge part and the outer shape of the cam.

Known hinge for the door frame described in patent RU 72008 U1, which we have chosen as the closest analogue. X adjustment in a known utility model is performed by a cam with a shoulder mounted in the upper half-loop and having a working surface with four angular sections of constant radius, creating four lines of constant contact between the cam and the internal cavity of the hinged part of the half-loop, regardless of their relative position. The disadvantage of this design of the loop for adjustment along the X axis is also the complex shape of the inner cavity of the hinge part and the shape of the cam.

Adjustment along the Y axis in the loops described in patents RU 2183717 and RU 72008 U1 is carried out by an eccentric sleeve located in the lower half loop with the possibility of a fixed orientation of the sleeve in several angular positions. The disadvantage is the disassembly of the loop when adjusting the pressing of the movable unit, because it is required to remove the eccentric sleeve from the lower half-loop to move to the next fixed position.

Adjustment along the Z axis in patent RU 2367757 is carried out by means of adjustment connected with an eccentric sleeve located in the half loop body and acting on the inner end of the shaft part. An element of the impact through which the adjustment takes place is a round plate, simultaneously transmitting movement to the antifriction sleeve. The disadvantage with this adjustment is the possibility of turning the adjusting screw in the process of opening and closing the door leaf, because torque is transmitted through the flat plate from the flat end of the rod to the flat end of the adjusting screw.

In the closest to the claimed patent analogue in the patent RU 72008 U1 for adjustment along the Z axis, a ball is used as a support bearing for transferring the impact from the adjusting screw to the end of the rod. A disadvantage of the known adjustment design is that the adjusting screw is eccentric relative to the ball contact spot (moving the contact spot when adjusting for height) and is located in the lower half-loop body, which does not allow for smooth adjustment of the moving block along the Y axis.

The listed designs of adjustable loops do not allow to exclude unauthorized removal of the moving block from the loops without violating the integrity of the loop parts and without preliminary disassembling the loop with a special tool when the moving block is open, in which the third condition of the distinguishing feature for outdoor moving blocks is not fulfilled.

The technical result consists in developing the design of the door security hinge with a locking device for removing the door leaf from the hinges, and simplifying its design. The claimed technical solution allows to exclude unauthorized removal of the door leaf from the hinges without violating the integrity of the hinge parts and without disassembling the hinge with a special tool with the movable block open. Simple in design, the shape of the control eccentrics can improve the manufacturability of the loop.

The specified technical result is achieved by developing a loop for the movable frame containing the upper and lower half loops, each of which has plates for attaching to the movable block and the fixed frame, respectively, with fasteners, a rod that rotates together the upper and lower half loops, an eccentric placed inside the upper half-loop with the possibility of rotation and mutual contact, an eccentric lock mounted in the side wall of the upper half-loop housing and interacting with basic element on the outer surface of the eccentric, adjustment means between the upper and lower half loops perpendicular to the plane of the movable block located in the lower half loop body and along the axis of the rod due to the set screw with a recess underneath the ball located in it, protective covers and pads, respectively covering the cavities of the hinged parts and fasteners To increase the safety against unauthorized removal of the movable block, the loop is made indivisible due to two internal ring hooks on the antifriction sleeve that engage with the annular grooves at the ends of the rod and the set screw, and the antifriction sleeve has slots to the height of the ring hooks, the rod is made together with an eccentric regulating movement parallel to the plane of the movable block, the outer surface of the eccentric sleeve with a shoulder has a groove for fixing the position I am a locking screw that is screwed into the lower half-loop body, the shape of the regulating eccentrics has a cylindrical shape and an angular sector with a radius at the apex, and the holes in the upper and lower half-loops in contact with the eccentrics have straight segments. The locking screws of the eccentric shaft can be made with a shoulder and the eccentric sleeve with a shoulder have a spherical surface at the end.

The device is illustrated by the following illustrations.

Figure 1 - presents a General view of the loop;

Figure 2 is a longitudinal section through a loop;

Figure 3 is a cross section of the upper half loop;

The inventive loop includes an upper half-loop body 1 and a lower half-loop body 2, which can be attached to the movable block and the fixed frame, respectively, by means of corresponding plates into which the corresponding threaded fastening means are inserted. The hinge contains an eccentric shaft with a shoulder 4, which allows two housings 1 and 2 to rotate relative to each other, and is inserted, respectively, by the eccentric part up to the shoulder into the hole of the upper half-loop body 1, and the lower cylindrical part through the antifriction blocking sleeve 6 and the eccentric sleeve with the shoulder 5 into the hole in the housing of the lower floor of the loop 2. The end of the cylindrical part of the eccentric rod with a shoulder - 4 has a recess that rests on the ball 8, which in turn rests on the installation screw 7. The anti-friction locking sleeve 6 is inseparable as a loop link - it has two internal ring hooks that enter the grooves on the ends of the eccentric shaft with shoulder 4 and the set screw 7. The inner surface of the hole of the eccentric sleeve with shoulder 5 prevents it from escaping meshing with the grooves of the eccentric shaft with the shoulder 4 and the set screw 7 of the ring hooks of the antifriction locking sleeve 6. Ring hooks prevent unauthorized removal erhney hinge part of the bottom. The hinged parts in the cases of the half-loop 1 and 2 are closed with protective and decorative covers 3 (Figure 1 and Figure 2).

On the outer surface of the eccentric rod with the shoulder 4 there is a groove for fixing the position of the eccentric rod with the shoulder 4 in the upper half-loop body 1 with the locking screw 9. (Figure 3).

The eccentric sleeve 5 has a groove on the outside for fixing the position of the sleeve 5 in the lower half-loop body 2 with the locking screw 10. (Figure 4).

The loop is installed as follows:

An eccentric rod with a shoulder 4 is inserted into the upper half-loop body 1 and fixed with the locking screw 9 in the middle position. An anti-friction blocking sleeve 6 is put on the eccentric rod with shoulder 4 until the hooks are fixed in the annular groove. Then, a ball 8 is inserted inside the anti-friction blocking sleeve 6 and is supported by the set screw 7 until the second ring hooks of the second ring hooks of the anti-friction blocking sleeve are latched in the ring groove. An eccentric sleeve with a collar 5 is put on the antifriction locking sleeve 6 with an eccentric shaft with a shoulder 4, a ball 8 and a set screw 7, and a screw 7 is screwed on the internal thread of the eccentric sleeve with a hex wrench through the hole in the lower part of the sleeve. The assembled unit is inserted into the lower half-loop body 2 in the middle position of the eccentric sleeve 5 and is fixed with the locking screw 10.

The use of one-piece adjustable loop of this design provides adjustment of the movable block relative to the fixed frame in three axes.

In horizontal position (X axis) by turning the eccentric shaft with collar 4 in the upper half-loop housing 1. To do this, loosen the locking screw 9, then use the hex key to turn the eccentric to the required position and fix it with the locking screw 9. When turning the eccentric shaft with the shoulder 4 there is a curved movement of the axis of the rod relative to the body of the upper half loop 1.

Change in depth perpendicular to the plane of the movable block (Y axis) is carried out by turning the eccentric sleeve with a shoulder 5 in the body of the lower floor of loop 2. To do this, loosen the locking screw 10, then use a hex wrench to be inserted into the corresponding hole in the bottom of the eccentric sleeve with a shoulder 5 , turn to the desired position and fix with the locking screw 10.

In the vertical direction, the adjustment is carried out by the set screw 7 through the hole in the lower part of the eccentric sleeve with a shoulder 5.

The inventive adjustable loop allows you to increase security - to exclude unauthorized removal of the movable unit from the hinges without violating the integrity of the parts of the loop and without first disassembling the loop with a special tool with the movable block open. Simple in design, the shape of the control eccentrics can improve the manufacturability of the loop.

The inventive loop meets the requirements of industrial applicability and can be manufactured on standard processing equipment using modern materials.
