Device for restricting the rotation angle of valve with a hook in the left cover and supporting hole in the right cover

FIELD: machine engineering.

SUBSTANCE: device for restricting the rotation angle of valve with the hook in the left cover and supporting hole in the right cover comprises a hook adapted to hinge the pad with a slot having a flared end facing the hinge joint. In this case, the hook is made longitudinally movable and passing through the flared end of the slot, with the possibility of meshing with the slot edge along its length during the valve opening. Thus, on the pad, a rack ratchet mechanism is made comprising a toothed rack, with at least one tothed recess in one of the longitudinal slot edges and provided with a squeezing handled clutch disposed to squeezing from the toothed recesses and movement in the slot between the right and the left covers, placed on the pad overlapping with the two longitudinal slot edges and to each other to move with each other and the clutch along the slot. In this case, the left cover has a hook to mesh with the bracket rigidly attached to the support with a movable hook. The right cover has a supporting hole with the hook possibility to pass through it after passing through the flared end of the pad slot. The left or the right cover has a supporting hole through which the squeezing handle is put.

EFFECT: improved device reliability.

The invention relates to doors with special devices and is intended for use in the construction and automotive

FIELD: construction.

SUBSTANCE: invention relates to construction and is intended for additional heat insulation of already installed single or double translucent part of a window structure. The technical result is achieved by application of an additional detachable lining attached to a translucent material (glass) of the already available window structure. The additional detachable lining is a translucent material (in this structure a glass or a polycarbonate sheet), to the surface of which a gasket is attached in a non-detachable manner to the perimeter, made of the elastic material (for instance, silicon) and spacers. The additional detachable pad is tightly applied to glass of the existing window frame, and in the gap between glasses there is vacuum pulled, thus providing for fixation of the detachable lining. Vacuum is pulled by an external device by pumping of air via a valve installed on the glass of the additional detachable lining, thus, a vacuum multiple glass pane is created, including glass of the additional detachable lining of the glass being a structural element of the already existing window frame. In order to create identical stress in the entire surface of the multiple glass pane produced in this manner, the surface of the additional lining glass equipped with a gasket and facing the surface of the glass of the existing frame, is equipped with evenly installed supporting points (spacers). At the same time in the initial condition (before pulling vacuum in the interval between glasses) the height of the gasket must be more than the height of the spacer. When vacuum is pulled, the elastic material of the gasket is compressed, being pressed to the window frame glass, and becomes equal to the height of spacers, providing for tightness along the glass contour. To remove the additional lining early, it is necessary to lift an edge of the valve opening a hole 6 and bleed air from glass-to-glass space. For reliability it is permitted to coat the surface of the gasket with silicon or other lubricant. To prevent air leak, transparent scotch tape may be adhered on top of the valve.

EFFECT: increased extent of heat insulation and noise insulation of a translucent part of existing (already installed) windows.

SUBSTANCE: invention relates to a stock for door lining, comprising the first main surface with an element of a structure formed on it, and the opposite second main surface. At least three sections stretching in longitudinal direction arranged at the distance from each other for placement of vertical bars are arranged on the second main surface. Two of sections for placement of vertical bars form the first width, and three of sections for placement of vertical bars form the second width larger than the specified first width. The stock for door lining may be squared to form door lining with selected width. Also the method is described for formation of a stock for door lining, as well as a forming press for formation of a door lining stock.

EFFECT: improved characteristics.

Flap turn limiter // 2551734

FIELD: transport.

SUBSTANCE: this device relates to catches and other locks for flaps, mainly for doors or windows. Particularly, it covers the limiters intended for locking of flaps in half-opened state by means of engaging/disengaging elements arranged at the frame and flap. This device comprises the catch and strap articulated at the frame. Said catch can turn about the axis parallel about the catch attachment surface edge. Catch has two hooking ledges bent toward each other to pass through two recesses in strap opposite lengthwise edges and hook thereon at flap turn. Strap end has at least one transverse thrust ledge to interact with said catch.

EFFECT: complete opening in the case if flap is pre-closed.
