A lock designed to close enclosures and / or gates in livestock buildings.

Abstract

The bolt (A) slides along its longitudinal axis within the bolt cage (C). The system is installed on a door (D) and locks into a locking piece (E). The rubber tube (B), held by the bolt (G), acts as a stop in both longitudinal directions. The bolt's locking lug passes through a window located on the bolt cage (C) and allows the bolt to be immobilized in the open or closed position by rotating the bolt handle. Fig. 4

Description

Title of the invention: Lock for closing pens and / or doors in livestock buildings

[0001] The present invention relates to a lock for closing pens and / or doors in animal housing (pigs, sheep, cattle, horses). These are used in farms, feedlots, wholesale markets, auction markets and slaughterhouses.

[0002] To date, the locks used to close the gates and parks are entirely metallic. They are often installed in stainless steel or galvanized metal cages, which are themselves installed on sheet metal assemblies.

[0003] Steel-on-steel friction causes noise and resonance in the door and even in the entire installation, which is composed of dozens of sheet metal panels assembled together.

[0004] The lock can also impact the locking piece opposite it if the latter is not correctly positioned. This also generates a shock and therefore a significant noise peak in the installation.

[0005] As part of our development efforts to improve animal welfare, we decided to limit this noise pollution in order to reduce stress for animals in the barns. We therefore decided to produce a steel lock overmolded in plastic.

[0006] To this end, the present invention relates to a lock for closing enclosures and / or doors in livestock buildings comprising a plastic overmolded lock with a steel lock core, the lock core being covered with a plastic material to dampen metallic noises and sound shocks.

[0007] The "INSO" lock and the metal lock retain the same external dimensions, thus allowing replacement of the locks already installed in all the barns we have installed.

[0008] This lock can be made in several lengths.

[0009] [Fig-1] is a cross-sectional view and a side view of a lock.

[0010] [Fig.2] is a perspective view of the lock.

[0011] [Fig.3] is a perspective view of a door and the lock intended to close parks and / or doors in livestock housing.

[0012] [Fig.4] is a perspective view of the lock intended to close parks and / or doors in the stables.

[0013] As illustrated in Figures 1 to 4, a latch for closing pens and / or doors in barns, overmolded in plastic with a CO core of the latch A Made of steel, the CO core of the A lock is covered with a PL plastic material to dampen metallic noises and sound shocks.

Claims

[Claim 1] Demands Lock (A) intended for closing enclosures and / or doors in housing, overmolded in plastic with a core (CO) of the lock (A) made of steel, the core (CO) of the lock (A) being covered with a plastic material (PL) allowing to dampen metallic noises and sound shocks.
