Definitions

  • the present invention relates to a display case with retractable glass. It particularly finds its application in the field of refrigerated display cases, used in particular in large areas to present food while keeping it at a given temperature.
  • the window located in a vertical plane is fixed to the front face of the frame so as to be able to slide down when it is retracted
  • the lower edge of the glass is fixed to the front face of the frame by means of a horizontal hinge connection so that the glass can pivot around a horizontal axis.
  • the exposure glass is found after retraction in the same vertical plane as that corresponding to its initial position, but at a lower level.
  • the purpose of the retraction operation is to facilitate access to the goods on display in the display case. It also simplifies the window cleaning operations, which are frequent in the case of refrigerated display cases serving as displays for food.
  • the two abovementioned embodiments have the drawback of applying only to panes having the simple form of a plate. Indeed, in the first case, the window to slide in a vertical plane must be plane. In the second case, taking into account the final position of the window after its retraction against the lower front part of the frame, the use of a large window would make access to the interior of the window difficult. The retraction of such a window would therefore be ineffective.
  • the aim set by the applicant is to offer a display case whose window can be retracted so as to facilitate access to the goods located inside the window, whatever the shape of this window or the volume it occupies.
  • this object is perfectly achieved by the presentation window with retractable glass according to the invention.
  • this comprises a window pivotally mounted on a frame, along a horizontal pivot axis.
  • the frame has a projection, and the pivot axis of the glass is located under the projection, to allow the retraction of the glass by pivoting thereof under said projection.
  • the projection of the frame must be designed so as to delimit a space that can serve as housing for the window after retraction; its size will depend on the shape of said window.
  • the display case comprises retracting means which consist, on the one hand of a support which is secured, by a first edge, to the pivot axis of the window, and of which the second edge, opposite to the first, is fixed to the lower edge of the window, and on the other hand to means for controlling the pivoting, around said axis, of the assembly formed by the support and the window.
  • the means of controlling the pivoting are able to pass the center of gravity of the support / window assembly beyond the vertical plane containing the pivoting axis. In this way, the space located under the projection of the frame is best used, by pivoting the support / window assembly until it comes to abut against the frame.
  • the means for controlling the pivoting consist of at least one jack, one end of which is integral with a first horizontal axis of rotation fixed under the support, the opposite end of which is pivotally mounted according to a second horizontal axis of rotation, and which develops a thrust P defining a lever arm d relative to the pivot axis, so that said thrust P compensates at least for the action of the weight of the support / glass assembly with respect to to the pivot axis, whatever its position.
  • the support / window assembly in the initial position before retraction, is held by said cylinder.
  • the retraction operation of the window under the advancement of the frame consists in constantly exerting on it a sufficient downward pressure, so as to at least counteract the thrust developed by the jack. If during the retracting operation of the glass one ceases to exert a vertical pressure, depending on whether the thrust of the jack is equal to or greater than the action relative to the pivot axis of the weight of the assembly support / window, the latter remains in equilibrium in the same position, or returns to its initial position before being retracted under the thrust of the jack.
  • the axes of rotation and the pivot axis are aligned when the center of gravity G of the support / window assembly is located in the vertical plane containing the pivot axis, so that the end of the jack , integral with the first axis of rotation, passes above the plane containing the second axis of rotation and the pivot axis, as soon as the center of gravity G passes beyond said vertical plane.
  • the display case furthermore comprises at least one cable, and winding and unwinding means, fixed at a first end of the cable, the second end being fixed under the support.
  • the winding and unwinding means consist of a first motor with two directions of rotation, driving in rotation a first shaft, and at least one pulley which is mounted on the first shaft, and on which is fixed the first end of the cable.
  • the unwinding or winding of the cable around the pulley depends on the direction of rotation of the motor.
  • the means of controlling the pivoting consist of a second motor with two directions of rotation, driving in rotation a second shaft which is fixed under the projection of the frame, and which constitutes the axis of horizontal pivoting.
  • the second edge of the support at its junction with the glass, is provided with a part for protection against impacts.
  • This is particularly useful to prevent a possible shock between the glass and the frame during the retraction. It also protects the glass against a frontal impact, when the latter is in the initial position before being retracted.
  • the display case according to the invention preferably comprises a system for locking the pivoting of the window when it is in the initial position before being retracted.
  • the pivoting control means consist of at least one jack
  • the locking system prevents accidental retraction of the window, caused by an involuntary pressure. More generally, it makes it possible to compensate for a possible malfunction of the control means. Indeed, to retract the window, it is necessary beforehand to unlock said system.
  • Refrigerated display cases are used to present food-type products for sale, and to keep them cool at a known constant temperature, low enough to obtain a relatively long shelf life. Such display cases should be cleaned frequently to avoid bacterial growth.
  • access to the interior of the showcase is from the rear.
  • this access can be achieved by the front of the display case, that is to say on the glass side. This facilitates the cleaning operations as well as the loading or unloading operations of the display case.
  • the retraction of the window 1 of the refrigerated display case according to the invention aims to allow such access.
  • the display case of FIG. 1 comprises a frame 2, consisting of a base 3 supporting in cantilever a substantially horizontal plate 4.
  • the front part of the plate 4 projecting constitutes a projection 5 with respect to the base 3.
  • a support 7 having the shape of a substantially rectangular plate.
  • This fixing is carried out using a hinge 8 secured to a first edge 10 of the support 7; this first edge 10 is the edge of the support closest to the base 3.
  • the hinge 8 defines a pivot axis 9 horizontal.
  • the second edge 11 of the support 7, which is opposite to the first edge 10, is integral with the lower edge 12 of the window 1.
  • This window 1 has a curved profile and is made of laminated glass.
  • This type of glass unlike Safety glass generally used in display cases, allows the production of panes having any shape and in particular strongly curved. Furthermore, during a possible violent impact against the glass, the laminated glass prevents it from being broken into several pieces.
  • the assembly constituted by the window 1 and the support 7 can pivot under the projection 5 thanks to the hinge 8.
  • its center of gravity G is in a vertical plane which is located between the second edge 11 of the support 7, and the vertical plane containing the pivot axis 9.
  • the window 1 and the support 7 tend under the sole action of their weight to rotate in the direction of arrow F.
  • each lateral edge 13 of the support 7 are pivotally mounted according to a first horizontal axis of rotation 16, the ends 15 of two cylinders 14.
  • the opposite ends 17 of the two cylinders are they also pivotally mounted along a second horizontal axis of rotation 18 fixed on the frame 2, at the level of the base 3.
  • Each cylinder 14 develops the same pressure P.
  • the pivot axis 9 is located above the plane containing the axes of rotation 16, 18.
  • the thrust of the jacks 14 defines a lever arm d, relative to the pivot axis 9. This thrust must be sufficient to compensate for the action of the weight of the support 7 / window 1 assembly with respect to the pivot axis 9.
  • the window 1 and the support 7 are thus kept in balance in their initial position before being retracted, by the thrust developed by the two cylinders.
  • the jacks 14 can be hydraulic or gas.
  • FIG. 3 shows the window 1 and the support 7 in their final position, once the retraction has been carried out.
  • the center of gravity G has passed beyond the vertical plane containing the pivot axis 9.
  • the action of the weight of the support / glass assembly relative to the pivot axis 9 therefore tends now to tilt it in the direction of arrow F '.
  • this action is compensated by the thrust of the jacks 14, the ends of which pass over the plane containing the second axis of rotation 18 and the pivot axis 9. Consequently, the window pane 1 and the support 7 are kept in balance in their final retracted position.
  • the window pane 1 and the support 7 abut against the base 3.
  • the space located under the projection 5 is used optimally.
  • the second edge 11 of the support 7 is provided over its entire length with a protective part 21 which acts as a bumper.
  • the display case which has just been described is which is shown in FIGS. 1 to 3 is also equipped with a first motor 29 with two directions of rotation, located in the rear part of the display case, and driving in rotation a shaft 32, the axis of which is perpendicular to the pivot axis 9.
  • a pulley 31 with double grooves is mounted on one end of the shaft 32.
  • the display case includes a cable 28a, a first end 28'a of which is fixed to a first groove of the pulley 31, and the second end of which 28 "a is fixed under the support 7.
  • the cable 28a passes around a first return pulley 30a, whose vertical axis of rotation 30'a is positioned relative to the pulley 31, so that the cable 28a when it is stretched, and is perpendicular to the axis pivot 9 between its second end 28 "a and the first return pulley 30a, is perpendicular to the axis of rotation of the shaft 32 between the two pulleys.
  • the display case also includes a second cable 28b, the end 28'b is fixed in the second groove of the pulley 31, and a second return pulley 30b.
  • This winding of the cables 28a, 28b has the effect of creating a tension at their ends 28 "a, 28" b fixed under the support 7. This tension which pulls the support 7 / glass 1 assembly downwards, swing.
  • the action of the jacks is identical to that which was described in the first exemplary embodiment.
  • the display case according to the invention differs from that shown in FIG. 1 in that the jacks have been replaced, controlling the pivoting of the support assembly 7 / window 1, by a second motor 33, with a double direction of rotation.
  • This motor 33 rotates a shaft, which constitutes the pivot axis 9 of the support 7 / glass assembly 1.
  • the motor shaft 33 is therefore fixed under the projection 5 of the frame 2 of the display case and the edge 10 of the support 7 is integral with said shaft.
  • the second motor 33 has a rotational movement in the direction of arrow C, the support 7 / window 1 assembly is driven in rotation downward, about the pivot axis.
  • the support 7 / window 1 assembly pivots upwards.
  • a stepping motor is used to properly control the rotation of the motor shaft, and thereby the retraction of the support assembly 7 / window 1.
  • the motorization of the pivot axis 9 of the support 7 / glass 1 assembly makes it possible on the one hand to avoid the use of jacks to control the pivoting of said assembly, and on the other hand to carry out an automatic retraction of the window of the display case.
  • the display case is preferably equipped with a locking system 22, which blocks the window 1 in its initial position before retraction.
  • a locking system 22 for maintaining the support 7 and the plate 4 secured.
  • This locking system 22 consists of a metal plate 23 pivotally mounted along an axis of rotation 26, through the support 7.
  • the upper end 24 of the metal plate 23 enters a cavity 25, formed in the lower wall 6 of the plate 4 near the front face 19 of the window 1.
  • the plate 23 is kept fixed in rotation by means of an elastic connection 27, such as a spring, fixed under the support 7.
  • the upper end 24 of the plate 23 cooperates with the cavity 25 to hold the support 7 and the plate 4 together.
  • the invention is not limited to the description which has been made of a particular embodiment of a refrigerated display case with retractable glass.
