Window opening limiter

Abstract

The utility model relates to the field of construction. The technical result consists of limiting the opening of a tilt-and-turn window by blocking the vertical upward movement of the movable window sash while maintaining the ability to tilt it. The tilt-and-turn window opening limiter comprises a locking unit mounted in a guide slot of the window slope. The locking unit is designed as a bolt and nut. The bolt is mounted with the head locating in the guide slot of the slope, and the nut is mounted on the bolt outside the guide slot with the ability to tighten. The locking unit is designed to be positioned in the lower portion of the guide slot in a position that blocks the vertical upward movement of the movable window sash while maintaining the ability to tilt the sash. The head of the bolt is elongated.Alternatively, the bolt head may have lateral grooves corresponding to the guide slot size. A wing nut is also acceptable. The locking assembly is also designed to slide along the guide slot and be secured in the selected position by tightening the nut. 4 s.p. f-ly, 1 fig.

Description

[0001] This utility model relates to construction, specifically window structures, specifically to devices for limiting window opening. The utility model can be used in tilt-and-turn windows to prevent unauthorized opening by blocking the vertical upward movement of the movable sash while maintaining its tilt-and-turn capability.

[0002] The device described in this application is intended for a tilt-and-turn window described in utility model patent RU 238041.

[0003] Various window opening limiting devices are known in the art. These devices are designed to improve the safety of window structures, prevent them from opening fully, and limit the movement of the window sash. Window opening limiters are known in the form of mechanical stops, locking elements, blockers, and other devices installed on the frame, sash, or window hardware, preventing the sash from opening beyond its intended opening range. Window locking devices, including child safety locks, are also known, limiting the opening of the sash or preventing it from opening without additional user intervention.

[0004] However, known devices, as a rule, have a relatively complex design, require the installation of additional parts on window elements or fittings, are not always convenient to install and operate, and can also limit the functionality of the window.

[0005] The problem that the claimed utility model is aimed at solving is the creation of a simple design limiter that would ensure blocking the vertical movement of a movable window sash, without interfering with the tilting of the sash.

[0006] The technical result consists of limiting the opening of a tilt-and-turn window by blocking the vertical movement of the movable window sash upward while maintaining the ability to tilt it.

[0007] The problem is solved by the claimed technical solution, which consists of a tilt-and-turn window opening limiter comprising a locking assembly installed in a guide slot of the window slope. The locking assembly is comprised of a bolt and nut. The bolt is mounted with its head locating within the guide slot of the slope, and the nut is mounted on the bolt outside the guide slot with the ability to tighten. The locking assembly is positioned at the bottom of the guide slot in a position that prevents the vertical upward movement of the movable window sash while maintaining the ability to tilt the sash. The bolt head is elongated. Alternatively, the bolt head may have lateral recesses corresponding to the size of the guide slot. A wing nut is also acceptable.

[0008] The fixing unit is also designed with the ability to move along the guide slot and be secured in the selected position by tightening the nut.

[0009] The essence of the utility model is explained by the drawing: Fig. 1 - shows a general view of the opening limiter of a tilt-and-turn window installed in the guide slot of the window slope;

[0010] The following designations are accepted:

[0011] 1 - window slope with guide slot; 2 - bolt; 3 - nut.

[0012] The tilt-and-turn window opening limiter comprises a locking unit installed in the guide slot of slope 1 of the window. The locking unit consists of a bolt 2 and a wing nut 3. The head of bolt 2 is positioned in the guide slot of slope 1, and wing nut 3 is screwed onto the protruding threaded portion of bolt 2. The locking unit is positioned at the bottom of the guide slot of slope 1 in such a way as to allow the window sash to tilt downwards while simultaneously preventing the sash from lifting upwards.

[0013] To prevent bolt 2 from slipping in the guide slot of slope 1 when tightening nut 3, the head of bolt 2 can be elongated. Alternatively, the head of bolt 2 can be provided with lateral recesses corresponding to the size of the guide slot.

[0014] An embodiment is also possible in which the nut is placed in the guide slot of slope 1, and a bolt equipped with a wing nut is screwed into the said nut from the outside.

[0015] The use of the specified locking unit allows, without the use of complex locking mechanisms, to limit the opening of a tilt-and-turn window by blocking the vertical upward movement of the sash while maintaining the ability to tilt it.

[0016] The device operates as follows.

[0017] Bolt 2 is installed with its head in the guide slot of slope 1, after which wing nut 3 is screwed onto the protruding part of bolt 2 and the unit is placed in the lower part of the guide slot of slope 1. After selecting the required position, nut 3 is tightened, fixing the unit in the guide slot.

[0018] When positioned this way, the locking unit creates a mechanical barrier to the window sash's upward vertical movement, preventing the window from opening in an undesirable position. However, positioning the unit at the bottom of the guide slot in slope 1 maintains the ability to tilt the sash.

[0019] Example. A tilt-and-turn window opening limiter was manufactured. It comprises bolt 2 and wing nut 3, forming a locking assembly installed in the guide slot of slope 1 of the window. The head of bolt 2 was positioned in the guide slot of slope 1, after which wing nut 3 was placed on the protruding portion of bolt 2, and the assembly was secured to the bottom of the guide slot. By positioning the locking assembly in the bottom of the guide slot of slope 1, a mechanical obstacle is created to the vertical upward movement of the window sash, thereby limiting the window from opening in an undesirable manner. At the same time, the sash remains capable of tilting, thereby achieving the technical result.

Claims
