RU2701219C1 - Assembly and method of barbecue grate handles (versions) - Google Patents

Abstract

FIELD: personal articles and house appliances.

SUBSTANCE: invention relates to connection of barbecue grate handles. Connection is achieved by means of movement of the shutoff element with applied force along elongated and shortened handles, containing during their contact, at least one pair of protrusions or recesses. In the point of lifting of the shut-off element, an additional force is applied to the ledge or at the outlet point of the recess, and when the recess passes or after the protrusion passes, the force is weakened.

EFFECT: excluding spontaneous movement of the shut-off element during operation of the device.

Description

The claimed group of inventions relates to a node and a method for connecting the handles of a barbecue grill designed to be held during cooking, for example, meat, fish, vegetables, etc.

The level of technology.

An analysis of the prior art revealed previously published Russian and foreign patents, the closest of which are the following analogues and prototype.

An analogue of the claimed technical solution is a barbecue grill, which contains two rectangular frames for fixing the cooked product between them, each of the rectangular frames made with handles made of wire rigidly attached to a grid made of wire rods located along and across the frame, with transverse and longitudinal rods are bent along two edges with the formation of side walls and together with another mesh cavity for placement of cooked products in it, the sides of rectangular frames to the opposite side, on which the handles are fixed, are interconnected by means of a pair of loops, one of the handles is shorter than the second handle, and a locking ring is put on the longer handle, located to move along the longer handle and put on the shorter handle when folding rectangular frames, at the intersection, the longitudinal and transverse rods are rigidly connected to each other, the wire of the handles is made thicker than the wire rods forming a grid, the wire of the longer handle is led out of the mesh to which this wire handle is attached, from the opposite side relative to this handle is U-shaped, and in the U-shaped portion outside the mesh, the wire is V-shaped bent in the vertical direction with respect to the mesh plane with the formation of two recesses for the stop of the curved edge of the mesh with the shorter handle, the edges of the mesh with the longer handle are smoothly curved, the middle of the holes of the pair of loops is from the edge of the mesh with the longer handle at a distance equal to the distance from the edge of the mesh with more than Ina handle mid V-shaped recesses, and a wire portion forming a shorter handle, and is adjacent to the bent wire forming a long handle upon application of meshes each other. As a result, simplification of operation is achieved by eliminating the possibility of injuries during transportation and operation of the barbecue grill when it is installed on the barbecue and ensuring self-centering of rectangular frames relative to each other when they are pressed against each other (patent for utility model of the Russian Federation No. 138228; publication date: 10.03. 2014; Patentee (s): Griffin Limited Liability Company (RU)).

A significant drawback of this analogue is the low reliability in fixing products between two rectangular frames, due to the fact that the locking ring during operation of the device can spontaneously slip from the handles, for example, when moving the grill on the barbecue or when turning it over and thereby cause the product to fall out of the grill .

The second analogue of the claimed device is a barbecue with a removable holder, containing a base to which a connecting element is rigidly attached at the front, made with the possibility of fixing the holder made of spring rods with a wooden pad, having bent antennae at the ends, mated in assembled condition with holes in the connecting element , a lid-clamp, having protruding stops on the rear side that engage with loop-shaped elements made on the base, and a handle, high falling from the front and secured by a latch, with the lid-clamp and base made in the form of a rectangular frame from a metal grill (RF patent for invention №2433776; publication date: 11/20/2011; Patent holder (s): RESHVET Limited Liability Company ( RU)).

The disadvantages of the second analogue are its complex design and method of bringing the device into working condition, as well as the insufficient reliability of fastening the cover-clip and the locking ring.

Another closest analogue, taken as a prototype, proposed for patenting of the device is a barbecue with a removable holder, containing a base to which a connecting element is rigidly attached at the front, made with the possibility of fixing the holder made of spring rods with a wooden pad having bent antennae at the ends, assembled with holes in the connecting element, a cover-clip having protruding stops on the rear side that engage with loop-shaped elements made on the base, and a handle protruding from the front side and secured by a latch, and the lid-clamp and base are made in the form of a rectangular frame of metal grating, characterized in that the base is equipped with a rod handle formed by a protruding elongated U-shaped part with a rounded the end, the free ends of which are permanently attached to the base, and the elongated part is inserted into the side flanges made in the form of two hollow half-cylinders formed by curved edges the specified connecting element, and is rigidly fixed in the latter, while the indicated flanges contain the spring rods of the holder, and their curved antennae are inserted into the through transverse holes made in the said flanges and directed outward from the longitudinal axis of the connecting element (patent for utility model of the Russian Federation No. 1,409,119; publication date: 05/20/2014; Patentee (s): RemiLing 2000 (RU) Limited Liability Company.

The main disadvantages of the prototype is the design complexity of the removable holder and low reliability in fixing the handles by locking the cover-clip on the base.

The technical result of the claimed group of inventions is the elimination of the above disadvantages: simplification of the design and method of bringing the unit into working condition, as well as improving the reliability of fixing the handles in a closed state due to the exclusion of spontaneous movement of the locking element.
