  The rigid conditions are imposed by the codes and regulations relating to the strength and load bearing capacity of the elevator cabs. In the prior art, platforms were constructed of irons. I and U irons joined to form a framework to which is attached a bearing surface, and the side walls were formed of solid metal continuous sheets or a laminated construction comprising a metal sheet The panels forming the walls are These constructions with solid walls are heavy, and in addition the solid or solid walls make it difficult to join to the platform because access to the fastening means is only possible. from outside the cabin In addition, the ceiling must be bolted to the side walls, from the outside

  Likewise, the important weight of the construction

  According to the prior art, the price of an installation

  particularly in a hydraulic system.

  An easy-to-build, light-duty elevator car construction that meets all code and regulatory requirements, economical to ship and

  easy to assemble on site is necessary.

  In general, according to the invention, a light weight, high strength and attractive looking elevator car construction is achieved. The elevator car comprises a light metal frame providing a structural support for the rear panels and Lateral walls The side frames are joined in a

  articulated to the rear frame members and the frame

  the rear has vertically oriented hinges for folding inwards,

  the rear frame between the side frames.

  When folded, the frame forms a package

  flattened which simplifies shipping and reduces its price.

  In the unfolded state, the panels hung on the frame conceal the hinged joints and also prevent the hinges from bending. Thus, a rigid and attractive lift cabinet wall construction can be obtained which can be placed on a platform. On-site elevator car, to be attached Lateral and rear surrounds include upper surfaces to support a ceiling board as required and include cutouts and lower panel supports for panel mounting and positioning. Attachment to the platform. shape of the cabin

  partial of a suspended panel of Figure 2.

  Referring to the figures, a light metal frame 10 for an elevator car with

  hanging panels according to the invention comprises a -

  right side frame 12, a left side frame 14 and rear frames 28, 30 The side frames 12, 14 are, at the base, flat structures having the shape of the inverted letter C. In particular, each side frame comprises a front pillar 18

  a base member 20 and a top iron or beam 22.

  As shown in Figures 1 and 2, the frames 12, 14 are constructed of metal profiles and angles rigidly joined in any suitable manner, for example by welding It will be understood that in other embodiments, other forms of structure The base flanges 24, for example, box-shaped members, may be used to form the members 18, 20, 22, and the flanges 24 for the floor extend inwardly from the base members 20 and include holes 26 for allow attachment of the metal frame of the elevator car to an elevator platform (not shown). The rear frame 28, 30 consists of two parts, the right side frame 28 having another inverted C-shaped structure similar to that of the side frames 12, 14 and a left-hand frame 30 The left-hand frame 30 has an inverted C construction whose open end is closed by a

  plate-shaped pillar 32 connected to a top beam

  The pillar 32 forms a flange 38 to which foldable hinges 40 are joined near the top and the bottom. The hinges 40 are connected to the upper beam 22 and to the base member 20. of the frame 14 on the left so that the frame 14 can be folded along the hinge 40 relative to the rear frame as can be seen in Figures 3 b, c An angle pillar 42, similar by its contour to the pillar 32, connects the upper beam 44 and the base member 46 of the right-hand rear frame 28 and hinges 40 connect the pillar 42 to the upper beam 22 and the base member 20 of the right-hand frame 12 so that the frame 12 can be folded with respect to the rear frame 28 as best seen in Figures 3b, c The vertical pillar 48 of the left-hand rear frame 30 is connected articulated to the upper beam e 44 and to the base member 46 of the right-hand rear frame 28 by upper and lower hinges 40 so that the rear frames 28, 30 are folded inwardly on the hinges 40 as can best be seen on the

Figures 3b, c.

  The vertical members of the side and rear frames 12, 14, 28, 30 comprise cutouts 50 on the inner surfaces thereof, i.e.

  surfaces that are in the space enclosed by the cabin.

  Furthermore, a panel support 52 is rigidly connected to each of the base members 20, 36, 46 The cutouts 50 and the supports 52 place the panels

  suspended, which offer decorative surfaces to the

  in the cabin as will be explained further below.

  The decorative panels 54-57 are suspended from the right side frame 12, the right side rear frame 28, the left side frame 30 and the left side frame 14 respectively. openings between the structural members of the side frames

  and back as well laterally as vertically.

  Clips 58 (FIGS. 4 a, b) are attached in a number of positions by securing means 60, to the rear surfaces 62 of the panels 54-57 at positions such that each clip 58 can be aligned with a

  cut opening 50 on the associated framing member.

  In cross-section (FIG. 4b), the clip 58 has the shape of a somewhat elongated S with the attachment means 60 holding an end surface 64 of the clip 58 against the rear surface 62 of the panel to form a door connection. The elasticity of the clamp 58 allows a flexion around the means of

  fixing 60 as indicated by the arrow 66.

  The lower edge of each panel includes a vertical slot 68 for engagement with the wing

vertical 70 of the support 52.

  To attach a panel, for example the panel 57, to the frame, for example the frame 14, the clamps 58 are aligned with the associated cuts 50 on the frame So, the clamp 58 is passed through the associated cutout 50 and the panel is moved downwardly, sliding on the surfaces of the metal frame so that the metal frame slides between the free end 73 of the metal clamp 58 and the panel itself. (FIG. 4b) The panel stops when the vertical wing 70 of the support 52 is fully retracted into the slot 68 at the lower end of the panel. The end of the panel rests on the horizontal surface 72 of the support 52. unless it is moved vertically, the panel can not be removed However, the panel can still be removed by raising it to remove the vertical wing 70 on the support 52 and aligning the clamps 58 with the cut out openings 50 So, the panel is easy to

remove from the coaching.

  Keeping in mind the objective of light weight, the decorative panel (Figure 7) is a laminate comprising a decorative veneer 74, for example formica or other plastic lamination, or a plastic material having the finish of mirror or the like This veneer 74 is mounted on a protective plate 76, for example hardened masonite The core 78 of the panel is a honeycomb made of plastic, paper or other light material Reinforcement 80, attached to the soul 78, forms a hard surface and is made of materials like

  for example, formica or other plastic fillings.

  Regulations and codes for

  passenger cabins, frequently require

  The panels 54-57 can not be removed from the interior of the cabin. Thus, in addition to the clamps 58 and the support 52, bolts 83 are provided which pass through holes 81 in the panels 54-57 and engage

  holes 82 in the internal framing surfaces.

  The bolts 83 have an enlarged head 84 and a body 86

  with a slot 88 cut in the far end.

  An elongated tab 90 fits into the slot 88 and is mounted on a pin 92 which travels through the slot 88 and is journalled in the body 86. While the elongate tab 90 is aligned with the longitudinal axis of the bolt 2545467. bolt 83 is inserted through the hole 81 in the panel, through the hole 82 in the frame and when sufficiently inserted and turned, the elongated tab 90, under the force of gravity, pivots downwardly around the spindle 92 at the 90 'position indicated in dotted line. Consequently, the tab 90 extends radially beyond the body 86 and it is no longer possible to remove the bolt 83 from the holes 81, 82 in the frame or panel while the tab is pivoted downwards. It is not possible to remove the panels from inside the cabin. In order to protect the decorative veneer 74 when objects such as furniture are moved in the elevator cabin, soft pads are frequently hung to protect the surfaces of the cabin walls. For this purpose, the bolt 83 is provided with a button 94 that extends from the more conventional head 84

  of the bolt Pads are hanging on the buttons.

  It will be appreciated that the bolt 83 may have sheet-type threads and that the holes 82 in the frame members may be unthreaded. Similarly, the bolt may have machine-type threads and the holes 82 in the frame members. may be threaded with corresponding threads, or a welded nut for example may be attached to the rear surface of the frame member for engagement with the bolt threads. In another embodiment, neither the bolt nor the holes are threaded and only the action of the clamps 58, the support 52 and the position 90 'of the tab of the bolt down prevents the panels from being removed from the inside of the cabin When the panels are held by the bolts 83, they can not be removed except by an action outside the cabin to bring the tab 90 in alignment

longitudinal with the body 86.

  An elevator car with suspended panels according to the invention has many

2545467 1

  advantages The construction is light because the solid metal panels have been removed from the walls in favor of a substantially open framing structure and hanging panels The frames 12, 28, 30, 14 can be articulated at the factory and shipped in folded condition as illustrated in FIG. 3 c Furthermore, the frame can be shipped as separate members 12, 14, 28, 30 for on-site assembly. After unfolding the frame (FIG. on an elevator platform (not shown) and is fixed to it by bolts passing through the holes 26 in the wings or flanges 24 of the floor This stiffens the structure A ceiling panel (not shown) can be placed at the top of the unfolded structure and be fixed to it by using bolts which engage holes 95 in the flanges of the upper beams 22, 34, 44 This further stiffens the structure As shown in FIG. 96 are connected to the pillars before 8 leaving

than an opening 98 for the door.

  It should be noted (FIG. 2) that the lateral panels 54, 57 extend beyond each articulated joint 40 and therefore that when the panels 54, 57 are placed on the respective frames 12, 14, it is not possible to bend the associated hinge 40 The structure is stiffened even when the ceiling panel (not shown) is not in place and the walls are not attached to the platform of

the elevator (not shown).

  Similarly, the panel 55 extends over the hinge

  in the rear wall of the elevator cabin.

  It should be noted that the hinge 40 between the rear frames 28, 30 is not centered and that the panel 55 hides the hinge 40 and also stiffens the hinged joint against bending while the panel is connected to the frame When the cabin is assembled and the panels are suspended, no hinges are visible and all the cutouts 50, the mounting holes 82 and the supports 52 are hidden.

  interruption is presented to the view.

  During construction work, before the lift is put into conventional use for example, as a passenger elevator, the cabin can be used for the transport of building materials, furniture and others. are reversible as long as the bolts 83 are not inserted or that access to the bolts 83 is possible from outside the cab Similarly, when assembling the elevator car, the connections between the frame and platform can be made both from the inside and outside of the cabin because the frame has an open structure Similarly, the ceiling panel can be attached to the frame either of the inside or outside the cab, again as a result of the open structure of the frame This is not possible when the wall panels are in a solid metal construction, as in the elevator cabins according to the prior art Thus, we o has a lightweight cabin with an attractive appearance, easy to manufacture,

  to ship and assemble on site.
