Definitions

  • the present invention relates to a device opening and closing an access door to a any pregnant.
  • the door in the open position, the door forms a plane substantially horizontal constituting a surface allowing the removal of dishes from the oven and also facilitating the cleaning of the internal face of the door since it is well cleared.
  • the object of the present invention is to remedy in particular to the above drawbacks by proposing a device door opening and closing which does not require no special clearance in front of the oven for open and close the door, while keeping the possibility of convenient access to the inside of the door to clean it.
  • the invention relates to a device opening and closing an access door to a enclosure, such as for example a baking oven, type including a chassis on which is mounted pivoting the door to allow tilting by relation to the enclosure, and which is itself mounted articulated on the enclosure by arms associated with frame to form an articulated parallelogram and allow the door to move relative to the plan of the enclosure access opening,
  • articulated parallelogram consists of two arms, of which the one or first arm is fixed by one end to a side of the enclosure and whose other or second arm is orthogonally angled, characterized in that the first arm is straight and is mounted articulated by its other end on the upper part of vertical uprights belonging to the chassis, and in that the second arm is mounted articulated by one end on the part middle of the vertical uprights of the chassis while the other end of this arm is either wedged on the shaft output of a geared motor group, either mounted articulated on one side of the enclosure.
  • the door will be opened or closed automatically, while in the second case, opening and closing will be ordered manually.
  • the device according to this invention is still characterized by a spring mounted between the point articulation of the first arm on the side of the enclosure, and the second arm.
  • the second arm is orthogonally bent to both about a third of its length, which will prevent it advantageously to abut on this or that element of the oven or the cabinet in which the oven is built.
  • Each bolt is likely to cooperate with a strike articulated mounting on the vertical uprights of the chassis to achieve locking security at door tilting when the latter works in translation mode.
  • each bolt is provided with a groove capable of cooperating with a hole in the keeper which is requested from permanently by a spring resting against the first aforementioned arm.
  • Figure 1 is a top view, upper wall removed, from a baking oven fitted with a device door opening and closing according to the invention.
  • Figure 2 is a schematic perspective view and partially exploded means according to the invention allowing the door to operate on both tilt and translate modes.
  • Figure 3 is an elevational and side view of the front part of the oven, shown in the closed position.
  • Figure 4 is a view similar to the previous one but showing the door in the partially open position by tilting.
  • Figures 5, 6, 7 and 8 are schematic views and side illustrating successively different positions of the door when opened according to the mode translation.
  • Figure 9 illustrates in partial view and from above the locking means for tilting the door, the left side of the figure illustrating the door in locked position, and the right side in position unlocked.
  • Figure 10 is a view similar to Figure 9, but illustrating the door seen from inside the oven, that is to say along arrow X in FIG. 1.
  • Figure 11 is a partial side view of the door, like figure 3, but illustrates, so enlarged security system door tilting when the latter operates in translation mode, the door being here shown in closed position.
  • FIG. 12 is a view identical to FIG. 11, that is to say showing enlarged and sideways, the upper part of the door, the latter being here represented at the start of opening according to the mode vertical translation.
  • Figure 13 is a partial schematic view of side of the joint of the two arms of a articulated parallelogram on the side of the enclosure, the lower arm being here equipped with a means susceptible cancel the action of the spring between the two arms, so as to allow the door to operate by travel with manual control.
  • enclosure 2 is schematically represented and has a bottom wall 3, an upper wall not shown in Figure 1 but marked at S on the Figures 5 to 8, two side walls 4 and a wall rear 5.
  • the enclosure 2 is surrounded by walls forming in sort of an envelope and defining the sides 6 of enclosure 2.
  • the walls of the enclosure, with the sides 6, define an opening 7 for access to the enclosure 2, this opening being closable by a door 8.
  • door 8 can be open and closed in two modes, namely by tilting of the door 8 relative to the enclosure 2 or by translation of this door 8 along a plane substantially parallel to the plane of the opening 7, at using the means which will be described below.
  • the door 8 is mounted on a frame 9 essentially comprising two vertical uprights 10 each having a U shape in section transverse and connected to arms so as to form two parallelograms articulated on the sides 6 of the oven 1.
  • the door 8 is mounted articulated in the lower part on the uprights vertical 10, so that it can be tilted or rotated around the axis XX ', following the arrow F.
  • Each articulated parallelogram consists of a first straight arm 11 of which one end 12 is articulated on the upper part of the vertical uprights 10, and of which the other end is mounted articulated at 13 on the sides 6 of the enclosure 2, while a second arm 14 is articulated by one 15 of its ends on the middle part of the vertical uprights 10, while the other end 16 of the arm 14 can either be connected to the output shaft of a gear motor group 47 (see Figures 5 to 8), in which case door 8 will be actuated automatically as described below, either articulated on the sides 6 of the enclosure 2, in which case the door 8 will be operated manually.
  • the axes of articulation of ends 12 and 15 of the first arm 11 and of the second arm 14 on the vertical uprights 10 are positioned vertically with respect to each other, as well as for the articulation axes of the ends 13 and 16 belonging respectively to arms 11 and 14.
  • the lengths between axes 12 and 15 and the lengths between axes 13 and 16 are equal, so that the four axes 12, 15, 16, 13 form a parallelogram articulated and deformable from axes 13 and 16 which are fixed on the device.
  • the door 8 can tilt according to the X-X 'axis, as explained above, but it can be opened or closed in translation vertical and substantially parallel to the plane of the access opening 7 to the oven 1, since, during the door 8 opening and closing operation, axes 12 and 15 will describe arcs of a circle in now said door 8 vertically, as we will explain this in detail later.
  • the second arm 14, as can be seen in 19 on the figures is bent orthogonally, the elbow in question preferably being two-thirds located about the length of the arm 14.
  • the bent part 19 of the second arm 14 has several reasons for being, namely in particular the size of the motor-reduction unit 47 on which obviously must not abut arm 14, the location of the drawer (no usually shown) at the bottom of the stove and on which the arm 14 should not either abut, or again the passage slots (not shown) of the arms 11, 14 at the level of the oven floor and beyond which said arms should not go.
  • geared motor 47 driving axis 16 can be controlled from a pulse given to a control keyboard (not shown), two switches marked at 20 in Figures 5 and 8 being provided to control the end positions of door 8 stroke closed and open.
  • the gear motor group 47 could be omitted, in which case end 16 of arm 14 can be articulated on the side 6 of the enclosure 2, as is the end 13 of the straight arm 11, so that door 8, in this case can operate manually and by translation substantially vertical, to open or close the enclosure.
  • a cam 20 integral of the arm 14 and provided with two notches or notches 21 able to cooperate with a pressure roller identified at 22.
  • FIG. 13 which is the door open position
  • the effect of the springs 17 door 8 balancing will be canceled, so that the door will remain in the open position, as shown in figure 8.
  • the door 8 can be opened by tilting around the axis XX 'on the vertical uprights 10 of the chassis 9, in order to perform a cleaning operation of inside this door or when you want simply use this opening mode.
  • a locking and locking system unlocking of door 8 on the vertical uprights 10 is provided on each side of the upper part of said door, as will now be described in referring more particularly to FIGS. 3, 4 and 9, 10.
  • the door tilt lock system 8 consists of two side bolts 23 which are stressed each by a spring 24 and mounted in the upper part and side of door 8. Each bolt 23 is constantly biased by a spring 24 so as to engage in orifices 25 formed in the vertical uprights aforementioned 10, so that door 8 remains locked on these uprights.
  • the keeper 28 is provided with an orifice 31 capable of cooperate with a groove 32 provided on each lug 23, and that we can see on the right side of the figures 9 and 10. The functioning of this security system is the next.
  • the striker 28 When the door is closed, as seen on the Figure 11, the striker 28 is supported on the arm oscillating 11 thanks to the springs 30. Consequently, the orifice 31 of the striker 28 is located in the axis of the bolt 23 the through, so that the release of the bolt 23 by the linkage 26 is authorized. Therefore, the door 8 can operate by tilting around the axis XX ' (see figure 4).
  • a device opening and closing of an enclosure such as a baking oven using a door that also works well by tilting than by vertical translation at using simple and reliable means and, moreover, with all the safety features required for locking and unlocking.
  • a door can advantageously be open or closed in a way automatic or manual.
