RU2367758C1 - Upper turnbuckle of fold with articulated rod allowing control by disabled people - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: invention concerns locking devices. Upper turnbuckle of fold with integral handle features rod of variable length with articulated link to handle. The rod has a handle in the form of rotating body coaxial to the rod axis, with smooth soft surface. Spring clips with opening oriented towards fold hinges or in opposite direction are provided for the rod and mounted under handle. Articulated link is flat and includes orifice at the handle end, with the orifice axis perpendicular to fold plane. Fixated pin inserted into the orifice enters orifices at the upper rod end. Rod can be connected to handle by globe joint.

Description

The invention relates to locking devices for sashes, mainly doors and windows.

Known articulated lever device for controlling a window and two locks: the lower and upper, with which the levers are pivotally connected, fastened to a vertical drive shaft mounted in the bearings on the frame, and a handle is fixed above the window sill on the lower end of the shaft. (DE 520684 A, 03/13/1931).

In the known solution, even a disabled person can control constipation, because the handle is at the level of the windowsill, i.e. in an accessible place for most people, but its disadvantages include its great complexity.

As the closest analogue, the upper rotary lock of the sash with an integral handle is adopted, equipped with a pull rod with a handle pivotally connected to the handle, the thrust serving as a convenience for opening and closing the sash when the person is in an uncomfortable position (or for a disabled person) and can be mounted permanently on the window frame. (DE 10039560 A1, 02.28.2002); The disadvantages of the known solutions include the inconvenience of using constipation.

The technical result achieved by the implementation of the claimed invention is to improve the ease of use of constipation.

The specified technical result is achieved by the fact that the upper rotary bolt of the sash with an integral handle, according to the invention, is equipped with a rod of variable length pivotally connected to the handle with a handle in the form of a body of revolution, coaxial to the axis of the rod, with a smooth soft surface, and for the rod spring-mounted under the handle latches with a pharynx facing the hinges of the sash or vice versa.

The swivel is made flat, containing mainly at the end of the handle a hole with an axis perpendicular to the plane of the leaf, into which a captive pin is inserted, which enters the holes in the upper end of the rod.

The rod is connected to the handle by a ball joint.

The fixed frame 1 is equipped with a sash in the form of a window 2 with hinges 3 (it is tightly closed, but not locked) and a rotary lock 4 with a handle 5, at the end of which a circular cylindrical hole (not shown) is made. The upper end of the rod 6, mainly in the form of a round cylindrical tube, is made forked with a diametrical slot open at the top for the handle 5 to fit freely. Perpendicular to the slot in the formed eyes (eye 7 is visible behind the handle 5, because the front eye is “removed”) of the fork at the end of the rod 6, the same holes are made as in the handle 5. Into the said holes, the geometrical axes of which coincide, a captive finger 8 is inserted with cotter pins (not shown) at each end of the finger. At the lower end of the rod 6, the handle 9 is fixed (screwed or screwed in) in the form of a body of revolution, coaxial to the axis of the rod 6, with a smooth (i.e. without sharp changes in shape) soft surface, for example, in the form of a polymer with decreasing elasticity to its surface, for reduce the force of inertial shocks on the glass with sudden movements of the window 3, for example, under the influence of wind gusts. The length of the rod 6 can be changed so that its handle 9 is as low as possible, but has a guarantee gap with a window sill, for which the rod 6 is assembled from parts, fastened with tie bolts 10 (one is shown). The rod 6 can hang freely, however, to prevent impacts of the rod 6 and the handle 9 on different surfaces with sharp movements of the window 2 below the handle 5, a spring latch 11 is fixed to the lower corner of the window 2, and the same frame latch 12 is attached to the frame 1, each latches 11 and 12 are turned to loops 3 of a window 2 or vice versa, since when the window 2 moves, the inertial forces are directed perpendicular to its plane, and if the pharynx has the same direction, it opens with a lower inertia force than when the pharynx is directed along the plane of the window 2. After the thrust 6, it is introduced into the yaw of the latches 11 and 12, immobilizing her.

The following describes the steps for locking the window through the rod 6 with a flat hinge. Starting position: the window 2 is open, the handle 5 is horizontal, the rod 6 is in the latch 11. The rod 6 is withdrawn by the handle 9 from the latch 11; creating a bending (bending) moment in the rod 6 with the hand, tightly close the window 2 (you can, with a small blow without rebounding), pull the rod down, handle 5 turns down, pull the rod further down, turning it so that it is at right angles to to handle 5 as far as possible (this provides the greatest turning moment on handle 5), therefore, the rotatable bolt enters its gap as if it were on an inclined plane (the bolt is wedge-shaped at its end), overcoming the friction force on the wall of the slot, the angle between the rod 6 and handle 5 ’dulls ", The turning point is weakening, but also the friction force weakens (the wedge is over), the handle 5 is lowered to a vertical position - the window is closed and locked. Rod 6 is introduced into the throat of the latch 11, then the latch 12.

Opening in the reverse order: pull the thrust from the throat of the latch 12, then 11, take it parallel to the window 2 as far as possible from the vertical towards unlocking the lock 4, pull it down at an angle, then deviate it to the other side from the vertical and push it up at an angle, forces there is less friction than when locking, so there is no longitudinal bending, bring the handle 5 to a horizontal position, the lock 4 is unlocked, pull the rod 6 in the direction of opening the window 2 to its desired position, introduce the rod into the latch 11.

A short (sufficient only for fixing) link of a known ball dyad, for example, with screws, is attached to the handle 5, the upper end of the rod 6 is attached to another (also short) link of the dyad, for example, the rod 6 is screwed into another link of the dyad. Everything else is as presented above.

Advantages of the ball joint: for tightly closing the window 2, the end of the rod 6 is diverted from the plane of the window 2 and loaded with longitudinal compressive force, it is clear from the decomposition of the longitudinal force that in this case the force applied perpendicular to the window 2 is much greater than the force obtained for due to the bending (bending) moment of the thrust 6 with a flat hinge, so the window 2 is pressed denser. The same thing when opening: the applied force is more.

The advantages of this invention:

1. Allows the disabled person to be more independent from the environment.

2. The rod can be fixed on the handle of the lock, long mounted on the sash.

3. Traction can be performed separately from constipation.

4. Traction can be rearranged from one lock on the sash to another.
