Each of the windows 6 is assisted in its

  pivoting by two weight compensation cylinders 7.

  According to an important characteristic, the refrigerated display case 1 with one or more horizontally pivotable and vertically liftable windows 6 and, with weight compensation cylinders 7 which assist this or these windows in its or their opening and closing movement comprises at least one ice whose parts between its connection points with pivoting hinges of this ice and its points of attachment with its compensation cylinders

  of weight, are directly under tension by these cylinders.

  According to another characteristic, the refrigerated showcase 1 comprises weight compensation cylinders 7 which have one of their ends mounted articulated and bearing directly on the pivoting and tilting windows 6 of the showcase, in other words, this end of these jacks is not articulated on supports or intermediate parts for reinforcing these windows 6,

  usually found in known refrigerated display cases.

  According to another characteristic, the refrigerated showcase comprises a bar 9 forming a fixed non-deformable assembly or frame, with these uprights or posts 3 and 4 of the frame 2 of the window and / or their end pieces 10 on which pivot pins 8 are fixed. windows 6 and hinge pins 11 of the rear ends of the

weight compensation cylinders 7.

  In the illustrated example, the individual or common uprights 4 of the frame 2 of the showcase I each comprise at their upper end a tip 10. The tip 10 is constituted by a substantially parallelepipedal piece provided with two transverse parallel rear holes 12 and central 13 respectively for the mounting of a pivoting pin 8 projecting double end (Figure 3) or an axis single projection not shown, for windows 6 and a hinge pin 11 projecting double end (Figure 4) or single protruding end (Figure 9) for rear ends of the weight compensation cylinders 7, an angled end 14 forming a clearance surface, parallel to the ice 6 (Figure 2), an end cut into a notch 15 for receiving a longitudinal edge of the bar 9, a recess 16 for lightening and receiving a head of a screw 17 for fixing the end piece 10 and the upright 3 or 4, at frame 2, assembly pins and rotational locking 18, 19 (Figures 4 and 5) penetrating into the recesses 20, 21 of an amount 3 or 4 to prevent relative movement between the tip 10 and the amount 3 or 4, and a receiving hole 22

  of a self-tapping screw 23 for fixing the bar 9.

  The bar 9 is constituted by a reflector sheath of lighting tubes 24 of the showcase, having a cross section C and extending along the length of the showcase I to connect the uprights 3 and 4 of the frame or their end caps 10 to form with these a fixed non-deformable assembly or frame. This reflector sleeve comprises spaced apart supports 25 for holding the illumination tubes 24 and their operating components such as a

  choke 26, and closed by a broadcaster 27.

  The lifting windows 6 are provided in their rear corners with rear fixing holes 28 intended to receive a screw fixing device 29 of a hinge 30. The hinge 30 is constituted by a substantially prismatic piece provided with a rounded end and an oblique end of clearance and two orthogonal holes 31, 32 for respectively receiving an axis of

  pivoting 8, and a screw 33 of the fixing device 29.

  A hinge fixing device 29 on an ice-cream 6 comprises on the one hand two paired washers with a large force distribution surface, namely a flat washer 34 and a tubular central collar washer 35 made of a synthetic material such as polyamide 6. 6, intended to coat the wall of the fixing hole 28 drilled in an ice sheet 6 and the edges of the two ends of this hole and secondly a wide flat flat rigid washer 36 and a nut with a large flat surface 37 in a rigid material having good mechanical strength, sandwiching the matched force distribution washers 34-35 and receiving under tightening a fastening screw 33 mounted with an elastic washer 38 through the

  hole 32 of the hinge and a hole 28 of the ice 6.

  According to another feature, the refrigerated showcase 1 comprises weight compensation cylinders which are provided at their front and rear ends with ball joint systems

rear 39 and before 40.

  In the example shown, the weight compensation cylinders 7 are known gas spring type cylinders comprising a closed tubular liner 41 which receives at one end a piston 42 whose tail is provided with a threaded end 43, and terminates at the other end by a threaded rod 44 or a tapped hole receiving a threaded rod 44. On the threaded end.43 and the threaded rod 44 are respectively mounted the rear ball joints

39 and before 40.

  The rear and rear articulation joints 39 and 39 comprise on the one hand a cylinder end piece 45 having the shape of a rectangular bend (FIGS. 4 and 7) provided in one of its ends with an axial hole 48 for receiving either a threaded end 43 of a piston 42 of a jack 7, or a threaded end 44 of a sleeve 41 of this jack 7, and in the other end, a spherical axial cavity 49

  open on the outside, and on the other hand for an articula-

  A sphere 50 secured to a hinge axis 11, and for a hinge system 40 to a sphere 51 secured to a screw 52 of a hinge attachment device 53

  mounted in one of the front holes 54 drilled in the ice

vables 6.

  The attachment device 53 of a front articulation system 40 of a jack 7 comprises, as a hinge fixing device 30, on the one hand two paired washers with a large force distribution surface, namely a flat washer. 34 and a washer with tubular central collar 35 made of a synthetic material such as a polyamide 6-6, intended to coat the wall with a front fixing hole 54 pierced in an ice cream 6 and the edges of the two ends of this hole, and on the other hand a nut with a large flat bearing surface 55 and a fastening screw 52 with a spherical projecting head 51 and a wide flat edge 56, which sandwich and clamp these paired power distribution washers 34, 35 in position on

this ice cream 6.

  In the example shown, the weight compensation cylinders 7 have their piston tail 42 and their liner 41 covered or masked by a concentric tubular casing 57 fixed by forced fitting on a tip of these cylinders, for example their

rear end 45.

  In an assembly of a refrigerated showcase 1, the ends 10 of the common uprights 4 for two adjacent windows 6 support (FIGS. 3 and 4) on their two lateral sides on the one hand two hinges 30 fixed respectively on these two windows 6 by means of fixing devices 29, and pivotally mounted on the two projecting ends of the axles 8 force-fitted in the rear holes 12 of these endpieces 10 of the common uprights 4 and secondly two rear articulation systems with a ball joint 39 of two cylinders weight compensation 7 of these two adjacent windows in which the two spherical cavities 49 of the ends of the cylinders 45 are mounted on the two spheres 50 terminating the two projecting ends of the hinge pins 11 force-fitted into the central holes 13 thereof. 10 end of the common amounts 4, while the tips 10 individual amounts 3 at both ends of the refrigerated showcase 1 only support that e on one of their lateral sides on the one hand a hinge 30 respectively fixed on an end window 6 by means of a fixing device 29 and pivotally mounted on a projecting end of a single projecting end axis 8 no shown forcibly in the rear hole 12 of these endpieces of the individual uprights 3, and secondly a rear articulation system with a ball joint 39 of a weight compensation cylinder 7 in which the spherical cavity 49 of a mouthpiece of cylinder 45 is mounted on a sphere 50 terminating a

  projecting end of an axle with a projecting single end

  11 (Figure 9) force-fitted into the central hole 13 of these

  tips 10 individual amounts 3.

  The front ends of the cylinders 7 with their front hinge articulation systems 40 are mounted directly on the

  ice cream 6 by means of fasteners 53.

  When an ice 6 of the showcase 1 is raised and pivots about the axes 8 of its hinges 10 from a closed position in

  solid lines (Figure 2) at an open position in dashed lines.

  tinus, the two weight compensation cylinders 7 mounted on the two lateral edges of this mirror 6 (FIGS. 1 and 2) which assist it in this movement, push the lens 6 by pivoting around their rear ball joint systems 39 and before 40 and lie down while relaxing. When this window 6 is lowered and brought from its open position in broken lines (Figure 2) to its closed position in solid lines, the two weight compensation cylinders 7 which assist in this movement, rotate around their rear articulation systems 39 and 40 before are shortening by compressing and opposing the weight of the ice 6 and slow down the descent thereof. The weight compensation cylinders 7 thus permanently underlie this ice in its parts situated between its connection points with hinges 30 and its points of attachment with these cylinders 7 and create a relatively large torsional torque which tends to cause a break

  6. However, according to the invention, the washers

  A wide force distribution surface 34, 35 associated with the wide-head 52 or wide-surface washer 36 and the large-surface bearing nuts 37, 55, in the fasteners 29 and 53 , effectively avoid this risk of

  breaking of the ice 6 due to these weight compensation cylinders 7.

  Fixing devices 29 and 53 thus advantageously allow

  removing the intermediate supports or intermediate ice-reinforcing parts 6 usually used in known refrigerated display cases, which are arranged between this window 6 and the jacks 7 for mounting them, in order to avoid a break

of this ice cream 6.

  In an opening or closing movement, the ice 6 which weighs all its weight on the projecting ends of the axes 8 of its hinges 30 and the weight compensation cylinders which push on their articulation axes 11, apply on the 3 and 4 uprights and their tips 10 a torque which tends to rotate them around their fastening screw 17 and exert a high stress which usually causes a break of the rear corners of the ice 6 at the fixing holes 28 of the hinges 30. However according to the invention, in a showcase I a bar 9 which is fixed by screws 23 in end notches 15 of the end pieces 10 of the uprights 3 and 4 of the frame 2 of this showcase form with these end pieces and uprights 3, 4, a fixed non-deformable assembly or frame which opposes any pivoting of the uprights 3 and 4 and their end pieces around the fixing screws 17, and consequently makes it possible effectively to avoid a risk of breaking the rear corners of this window 6 of the window in a movement of opening or closing of

the latter.

  In order to improve the solidity of the holding of pivot pins 8 and hinge pins 11 and the immobilization of these pins against their rotation in mounting holes 12 and 13 of end pieces 10, these pins 8 and 11 are provided in their respective zones. contact with the wall

  of these holes, grooves or asperities 60.

  In the end pieces 10 of the uprights 3 and 4, the lightening and receiving recesses 16 of the fixing screw head 17 can be closed by covers (FIGS. 4 and 5) which improve

the aesthetics of the showcase 1.

  In addition, in order to avoid any undesirable free translation of the hinges 30 on the projecting ends of the pins 8, circular grooves 65 are formed in projecting ends of these pins 8 to freely receive, in relative displacement, fixed pins 66 for locking the hinges in translation 30 (FIG. 2), pins forcibly mounted in corresponding holes 67 (FIGS.

  2 and 6) pierced in these hinges 30.
