Device for fixing the gate leaf in open and closed positions

Abstract

This utility model relates to devices for locking swing gate leaves in the open and closed positions. The device comprises a housing made of profile tubing with a rack and guide slot for the stopper, as well as a stopper with reinforcements and a centering bar. Distinguishing features include reinforcement inserts for the lever, plastic end caps on the housing, covers on the rack with conical holes, and the ability to install without welding using HARPOON self-tapping screws in most cases. The technical result ensures universal installation on any gate support with fastening to the gate support and to the gate via adjustable lever-bracket assemblies, secure fixation, ease of installation, and durability due to the absence of friction points and protection from atmospheric influences. This model is intended for use in private and industrial construction for the installation of swing gates with inward and outward opening.

Description

[0001] Technical field

[0002] This utility model pertains to construction equipment, specifically to devices for fixing the position of swing gates, and can be used to securely hold the gate in its extreme positions - "open" and "closed." The device is designed for use in outdoor environments and garage doors, suitable for installation on left and right gates, as well as on gates opening both outward and inward, on round and square posts up to 115 mm in size with a lever (8), and on posts and walls larger than 115 mm with a lever (36). The design allows for quick installation on various types of supports - profile pipes and round posts - using a universal fastening system. The device does not require maintenance or preventive maintenance throughout its entire service life.

[0003] Technology Level

[0004] Descriptions of inventions and utility models returned by an advanced search on the Rospatent website for the query "device for fixing swing gate leaves" were reviewed. 39 results were received; no similar design was found.

[0005] Devices for locking gates are known, including stops, pins, and magnetic and mechanical locks. For example, DEVICE FOR LOCKING A SWING GATE LEAF IN THE OPEN POSITION RU 132471 U1 2013.09.20 contains a pedal for setting it into the operating position and a threaded axle around which a support pin rotates at a right angle to it.

[0006] Gate control devices with electric drives are known, in particular, the DEVICE FOR OPENING AND CLOSING GATE LEAF RU 2 142 547 C1 1999.12.10. However, this solution requires electricity. In the absence of power, opening, closing, and latching the gate in the open and closed positions involves locking and unlocking the device.

[0007] There are also mechanisms with spring stoppers, but they often lack position adjustment, convenient manual release, or installation flexibility. Furthermore, most similar mechanisms do not automatically lock the sash when closing from the outside, while still allowing release only from the inside—which is important for safety.

[0008] Therefore, there is a need for a simple, reliable and universal device that can fix the gate leaf in both open and closed positions, with the ability to automatically lock when closing from the outside and from the inside and manually open only from the inside.

[0009] Disclosure of Utility Model

[0010] This device is based on a hook-type lock. The main difference is that the hook must be opened and closed manually, and it is not weatherproof.

[0011] The device opens manually, fixes the desired position of the gate leaf, when the lock is aligned with the corresponding hole automatically.

[0012] The device has a housing with a slot for moving the stopper in the bottom part and plastic end caps, which protect the device from weather conditions.

[0013] The device does not have any components that require maintenance or lubrication.

[0014] The objective of the utility model is to create a device for fixing a gate leaf that ensures:

[0015] - reliable fixation in two extreme positions “open” and “closed”;

[0016] The technical result is achieved due to the special design of the body, a rail with holes, a stopper, as well as through the use of brackets with adjustable lever positions, adapted for mounting on profile pipes with a cross-section of 80 mm and 100 mm, as well as on round pipes with a diameter of 80 mm and 115 mm, installation with an impact wrench or screwdriver using HARPOON* self-tapping screws.

[0028] Implementation of a utility model

[0029] The device comprises a housing 1 made of a profile pipe, inside which a rail 16 is welded through openings 41, with linings 15 with conical openings 14 to eliminate play between the rail 16 and the stopper 18, inserts 19 made of a profile pipe are welded into the end of the housing to reinforce the opening 6 of the axis 20 of the levers 7 and 38, plastic plugs 11 and 21 are inserted into the ends of the housing, along the bottom part of the housing 1, from the side of the plug 11, a longitudinal slot 32 is cut for longitudinal movement of the stopper between openings 13 and 34 on the rail 16, serving as positions of the locked state of the device, in the slot 32 an extension 33 is made for mounting the stopper 18 with the centering bar 4 in the housing 1.

[0030] The body 1 is attached to the support by means of an adjustable unit, tightened with bolts 23, through the axis 20 inserted into the hole 6:

[0031] for opening the sash 35 outward for supports, with installation method 24, 25, 26, 27, consisting of a lever 7 and a bracket 9 with oblong holes 36 and mounting strips 8, self-tapping screws 10;

[0032] for opening the sash 35 inward for supports, with installation method 28, 29, 30, 31, consisting of a lever 38 with an oblong hole 39 and a bracket 9, with self-tapping screws 10 on a prepared platform;

[0033] for opening the sash 35 outward onto the support 40, wider than 115 mm, consisting of a lever 38 and a bracket 2 with oblong holes 5, self-tapping screws 10 onto a prepared platform.

[0034] The body 1, through the slot 32 with the rail 16, rests on the stopper 18 in the hole 13 or 34 in the closed state or slides with the rail along the stopper during the rotation of the gate leaf 35 on the canopy 37.

[0035] Stopper 18 with reinforcements 17, welded into lever 3, forming an adjustable unit with bracket 2, tightened with bolts 22, is fastened to the gate leaf through the mounting plate with self-tapping screws 12.

[0036] On the rail 16, inserts 12 are welded for distance with the body 1 and linings 15 with conical holes 14.

[0037] The device operates as follows.

[0038] To open or close the gate leaf, lift the housing 1 by the end opposite the fastening to the leaf support, which disconnects the stopper 18 from the hole 3 or 32 in the rail 16, push the leaf and release the housing, with further movement of the leaf when the stopper 18 is aligned with the hole 3 or 32, under the action of the gravity of the housing 1, the leaf will automatically lock.
