Definitions

  • the invention concerns a door lock system, designed for mechanical door lock, of an oven cavity in particular.
  • the lock prevents opening the door of the oven or other equipment operating at an elevated temperature, for example by a child.
  • the use of the lock in the door of this type of equipment is to reduce the risk of burns when opening the door unattended during operation.
  • a locking mechanism built inside the oven door panel is provided with a latch on a spring and a slider ended with a handle on the outer side of the door panel and operating in a direction perpendicular to the plane of the oven door.
  • the catching element comprises an aperture in the bracket fixed to the front wall of the oven and an outwardly projecting above the door.
  • the latch inserted into the opening of the catching element locks the oven door.
  • the slider of the locking mechanism controls the position of the latch and locks its position when released.
  • the aim of the present invention was to develop an uncomplicated mechanical system, effectively hindering opening the door while the appliance is in operation, that is easily installed in the appliance and easily removed, and also characterized by an aesthetic appearance and a low cost of manufacture.
  • Door lock system of an oven in particular, according to the invention consists of a locking mechanism fixed to the front part of the appliance body, equipped with a slider ended with a holder and spring, and the accompanying catching element fixed to the appliance door, characterized in that the helical cylindrical spring and the cylindrical end of the slider are slid over the guide in the base of the locking mechanism.
  • the base is made of a flat bar, the ends of which are twice bent at a right angle so that the first bent sections form vertical walls to which are fixed the ends of the guide, and the distal sections are bent outwards and have mounting holes for fixing the locking mechanism to the front part of the appliance body.
  • the middle part of the slider has the shape of a flat hook working with the catching element rigidly fixed to the upper part of the appliance door panel.
  • the catching element is a pin which, in the closed position of the appliance door, is located in the space limited by the inner edges of the hook, preventing the appliance door opening.
  • Door-locking system according to the invention consists of a small number of elements of a simple design. Additional advantages of the system according to the invention is the ease of installation and removal of the locking element (mechanism), by screwing or unscrewing two screws. The feasibility of making the locking mechanism from plastic ensures quiet lock operation and aesthetic design.
  • Fig. 1 shows an overall view of the front part and door of the oven with the installed elements of the locking system
  • Fig. 2 is an axonometric view of the locking mechanism
  • Fig. 3 is a view of the door lock system in locked position
  • Fig. 4 is a view of the door lock system in unlocked position
  • Fig. 5 is a view of the locking system in cross-section, in a plane perpendicular to the oven door and passing through the centre of the pin.
  • Oven door lock system 6 consists of a locking mechanism 1 , fixed to the front wall 2 of the oven, jointly operating with a pin 3 rigidly fixed to the top of the panel 4 of the door 5, which is a catching element of the door lock system 6 .
  • the locking mechanism 1 consists of a guide 7 , slider 8 , and spring 9 , built in the base 10 .
  • the base of the locking mechanism 10 is made of a flat bar, the ends of which are twice bent at a right angle so that the first bent sections form vertical walls 11 between which there is a guide 7 , and the distal sections are bent outwards and have mounting holes 12 for fixing the base 10 to the front part of the appliance 2 .
  • a helical cylindrical spring 9 and the cylindrical end 13 of the first end of the slider 8 are slid over the guide 7 .
  • the slider 8 can move linearly along the guide 7 in the range limited by a side wall 11 of the base 10 and spring 9 , which holds the slider 8 in the most outward position, pushing the slider 8 to the side wall 11 .
  • the other end of the slider 8 is permanently attached to the handle 14 for slider 8 operation.
  • the middle flat part of the slider 8 has a rectangular shape and its end has the shape of a rectangular trapezoid, adjacent to the central part with its longer base in such a way that the right side of the trapezoid is an extension of the rectangle side, and the shorter base equal to the width of the central part of the slider 8 is connected to the handle 14.
