Definitions

• the present invention relates to a cooking device to which the cook top is mounted whereon cooking processes are performed.
• the cook top disposed on the top surface of cooking devices including burners thereon for performing the cooking process is produced of steel sheet and coated with enamel.
• the enamel coated cook top is being mounted on the frame, it can be subjected to tensions and impacts and this may result in damaging the enamel, which is a fragile material.
• connection springs are used to resiliently mount the cook top on the frame; however, enamel cracking cannot be avoided while mounting the cook top particularly on the frame.
• German Patent Document No DEl 9613320 a work surface fixing system used in household appliances is explained.
• the fixing system comprises a pair of spring sockets at opposite ends of the switch panel extending across the top front edge of the household appliance.
• the aim of the present invention is to the realization of a cooking device wherein the cook top can be mounted easily.
• connection springs that are previously fastened to the upper surface of the frame which forms the skeleton of the body or to the front panel.
• connection spring comprises a fixing extension for assembling thereof to the frame and a resilient extension for attenuating the impacts by leaning on the bent side of the cook top, shaped as an inverted V, one arm of the V shape connected to the fixing extension and the other arm bearing on the front or lateral side of the cook top.
• the resilient extension comprises an continuous forehead surface that stretches the cook top backwards by the bent sides of the cook top pushing while the cook top is mounted by pressing downwards and a pressing extension that curves inwards by bending the forehead surface concavely that compresses the cook top by leaning on the side of the cook top seated on the frame or the front panel.
• a supporting protrusion is provided on the frame or the front panel that restricts the forwards, backwards motion of the connection spring and the connection spring is assembled by being seated on the supporting protrusion by means of a depression disposed on the fixing extension.
• a channel is arranged on the fixing extension and the connection spring is assembled on the frame allowing thereof to slide along the channel.
• a resilient extension is situated on the rear side of the connection spring and this extension increases stretching of the spring by leaning on a supporting protrusion arranged at the rear.
• stoppers are provided on the cook top that prevent the sideways movement of the cook top by leaning on the connection springs.
• the front side of the cook top is in the curved form and the connection springs are positioned angularly with respect to each other and in the vertical direction to the curved front side of the cook top such that the cook top is mounted on the frame by pressing down thereon.
• Figure 1 - is the perspective view of a cooking device body and a cook top.
• Figure 2 - is the perspective view of a cooking device after the cook top is mounted thereon.
• Figure 3 - is the view of detail D in Figure 2.
• Figure 4 - is the perspective view of a connection spring.
• Figure 5 - is the cross- sectional view of a connection spring.
• Figure 6 - is the perspective view of a connection spring including a channel at the center.
• FIGS 7, 8 - are the perspective views of connection springs including additional resilient elements.
• Figure 9 - is the schematic view of a cook top with a curved front side and the connection springs positioned angularly with respect to one another.
• the cooking device (1) comprises a body wherein the cooking process is performed on the upper surface and/or the interior volume, a front panel (2) including the elements such as knobs and displays thereon, a cook top (3) mounted on the body, containing the gas burners and/or electrical heating plates for heating and/or cooking and a frame (4) to which the walls forming the body, the front panel (2) and the cook top (3) are fastened ( Figures 1, 2).
• the cook top (3) is produced by shaping the steel sheet material and coated with enamel.
• the cook top (3) comprises at least one side (12) formed by bending downwards the portions corresponding to above the front panel (2) and the frame (4) ( Figures 1, 2, 3, 5).
• the cooking device (1) furthermore comprises a connection spring (5) that provides attaching the cook top (3), which is mounted to the frame, to the frame (4) to be re- siliently and attenuating the forces acting on the cook top (3).
• a resilient extension (7) shaped as an inverted V, one arm of the V shape connected to one end of the fixing extension (6) and the other arm leaning on the side (12), that stretches backwards by the side (12) of the cook top (3) pushing while the cook top (3) is mounted by pressing down, that returns to its former position when the cook top (3) is properly seated on the frame (4) and exerting force on the side (12) from the inside so that the cook top (3) is attached on the frame (4) by pressing down ( Figures 4, 5).
• the resilient extension (7) comprises an continuous forehead surface (A) disposed on the front side thereof over which the side (12) slides and pushes backwards while the cook top (3) is mounted by pressing down and a pressing extension (B) that curves inwardly by bending the forehead surface (A) concavely which compresses the cook top (3) by leaning on the inside of the side (12) seated on the frame (4) ( Figure 4).
• the continuous form of the forehead surface (A) provides the stretching of the resilient extension (7).
• connection spring (5) is fixed to the front panel (2) or the frame (4) by means of the fixing extension (6).
• the cook top (3) is brought over the frame (4) and after the burner head openings on the cook top (3) are aligned with the burners, the cook top (3) is lowered to be seated on the frame (4) ( Figures 1, X).
• the rear side of the cook top (3) is fixed by fastening elements such as screws or the like.
• the front and lateral sides (12) of the cook top (3) are bent downwards.
• the front or the lateral side (12) slides on the forehead surface (A) of the resilient extension (7) in front of the connection spring (5) and stretches the resilient extension (7) backwards and after passing beyond the forehead surface (A) goes under the pressing extension (B). Assembling is completed by compressing the side (12) between the pressing extension (B) and the frame (4) or the upper surface of the front panel (2).
• the resilient extension (7) does not stretch easily since the spring constant is high, only stretches under excessive forces, preventing cracking of the enamel coating of the cook top (3).
• the cooking device (1) comprises a supporting protrusion (8) disposed on the frame (4) or the front panel (2) that restricts the forwards, backwards motion of the connection spring (5) ( Figure 5).
• the motion of the connection spring (5) in the forwards, backwards directions is restricted by fixing on the supporting protrusion (8) or by bearing on the supporting protrusion (8), the movement of the cook top (3) in the forwards, backwards directions is attenuated only by the stretching of the resilient extension (7).
• connection spring (5) comprises a depression (9) for assembling thereof by being seated on the supporting protrusion (8), disposed on the fixing extension (6) and formed preferably by bending the fixing extension (6) ( Figures 4, 5).
• connection spring (5) comprises a channel (10) arranged on the fixing extension (6) for assembling thereof on the frame
• connection spring (5) is attached to the frame (4) or the front panel (2) by a fastening element such as a screw, pin etc. that can move inside the channel (10) formed on the fixing extension (6) and attenuates the movement of the cook top (3) in the forwards, backwards directions by means of the channel (10) and also by the stretching feature of the resilient extension (7).
• the cooking device (1) comprises one or more stoppers (11) situated on the cook top (3) that prevent the sideways movement of the cook top (3) by contacting to the connection spring (5) from the side ( Figure 9).
• the cooking device (1) comprises a cook top (3), the front side configured to be curved that is mounted on connection springs
• connection spring (5) furthermore comprises additional resilient elements that extend along the rear and lateral sides thereof that increase the attenuation of impacts acting on the cook top (3) ( Figures 7, 8).
• additional resilient elements that extend along the rear and lateral sides thereof that increase the attenuation of impacts acting on the cook top (3) ( Figures 7, 8). The movement of the cook top (3) both in the forwards, backwards and right and left directions is attenuated by means of the additional resilient elements.
