Description

The invention relates to a cabin for cable cars for receiving passengers and / or goods according to the preamble of independent claim 1.

Boxes or cabins for gondola lifts, in particular cable gondolas, are known from the prior art, whose load-bearing elements consist of a floor frame, a roof frame and at least four corner pillars connecting the floor frame to the roof frame. Such a cabin is used for example in EP 1619099 A1 described. On the supporting elements are two opposing side walls, of which has at least one door opening, two opposing end walls, a floor and a roof arranged. In particular, the end walls and the door opening opposite side wall are equipped with large windows.

In the known gondola lifts, the window panes of the cabins are inserted in grooves which are provided along a window frame of the cab. In the grooves between the window frame and window also a rubber strip for holding or clamping the window pane is inserted. The glazing can also be glued into the grooves.

In the known gondola lifts, this structure has been well proven under normal operating conditions. In special circumstances, however, has proven to be disadvantageous that the windows were released from the window frame, so that persons or goods have come to harm. If an in-progressing cabin, for example, by an obstacle or rope derailment within less Stopped in milliseconds, the persons or goods in the cabin are pressed against the inside of a window pane. The forces occurring can be sufficiently large to push out the window pane from the clamp in the window frame. A major disadvantage is that, for example, people fall out of the cabin and can be harmed. Another disadvantage is that the leached window can fall down and below the cabin can seriously endanger people and animals. Even when the car is stationary, the glazing can, for example, be pushed out of the window frame or the holder by considerable force.

The document DE 2336375 discloses a windshield mount for motor vehicles in the region of an edge of the windshield on a windshield frame, which is arranged on the body structure of the motor vehicle.

The present invention is therefore based on the object to overcome the disadvantages of the prior art. In particular, people and goods should be protected from falling out of the cabin.

These objects are achieved according to the invention by a cabin having the features of claim 1. Advantageous developments of the inventive cabin will be apparent from the dependent claims.

An essential feature of the present invention is a cab for cabins for receiving passengers and / or goods, with an opening and with a bracket fixed to the cabin for holding a glazing in the opening, wherein the cabin comprises at least two connecting members, each having a first comprising the glazing connected fastener and a second connected to the cabin fastener, wherein the glazing is held by means of the connecting members in the region of the opening when the glazing dissolves from the holder. One of the advantages of the invention is that the connecting member the glazing itself then joins the cab when the glazing pops out of the mount, as is caused by a heavy impact by a passenger against the inside of the glazing. This can prevent people or passengers or goods from falling out of the cabin. The device according to the invention thereby ensures the safety of the passengers. Another advantage is that the combination of glazing and connecting elements, similar to a rope fixed at two points, additionally holds the cabin together. It has proven to be advantageous that the respectively first and the second fastening element of a connecting member are arranged so that the extension of an imaginary connecting line between the two fastening elements approximately cuts through the center of the glazing. Preferably, the connecting members are uniformly spaced from each other. According to the invention, the first fastening element and the second fastening element of a connecting element of the car are connected to one another by means of a bendable and / or flexible connecting element. One of the advantages of the invention is that the expansion caused by temperature variations of the materials of the cabin, in particular in the glazing and the holder, can be compensated in the connecting organs. Thus, material stresses can be compensated via the bendable and / or flexible connecting element. Another advantage over a rigid connecting element is also that the connecting element can withstand through its elastic and deformable properties loads of various types, for example. By pressure, train and torsion. Flexible means being able to adapt to changing conditions, to be ready to react or to be flexible, elastic, yielding. These Flexibility is also necessary because the load direction, for example, that of a passenger, for glazing in an exceptional situation, eg. A rope derailment, is not known.

In another embodiment, the connecting element of the car consists of a bendable and / or flexible cable section. One of the advantages of the invention is that a rope consisting of several strands and corbelets has the necessary elastic properties in order to withstand the possible loads. The cable section is preferably made of a steel cable. The steel cable is virtually destructive by wanton manipulation.

In one embodiment, a sleeve is connected to at least one end of the cable section. One of the advantages of the invention is that the mechanical connectability of the cable section to the cabin and / or the glazing is facilitated. This embodiment allows a secure mechanical connection of the end portion of the connecting element with the cabin and / or glazing. Compared with a loop formed by means of the cable section, the proposed sleeve allows a more compact construction. The connection between cable section and sleeve can be made by compression, welding or other means.

In another embodiment variant, the first fastening element of the cabin has at least a first and a second fastening part clamping the glazing, and the first and the second fastening part are connected to one another by holding means. One of the advantages of the invention is that by means of the fastening parts a preferably permanent attachment of the connecting member of the cabin is ensured on the glazing. As holding means serve, for example, screws, which are protectable against manipulation. The detachable connection allows the glazing to be replaced at any time by qualified personnel.

In one embodiment variant, the glazing is connected to the cabin by means of a multiplicity of connecting elements. One of the advantages of the invention is that, for example, depending on the area of the glazing, two, three, four or more connecting members are used to secure the glazing. The connecting members can, for example, be fastened crosswise in the region of the corners of the glazing. Depending on the configuration of the glazing and other arrangements of the connecting members are possible.

In a further embodiment, the holder of the cabin comprises a plurality of individual holders, by means of which the glazing can be connected to the cabin. In another embodiment variant, the holder comprises a frame holder encompassing the glazing, by means of which the glazing can be connected to the cabin. In a further embodiment variant, the glazing of the cabin is at least partially connectable to the frame holder without joining the joint. One of the advantages of the invention is that the connecting members for securing the glazing with the cabin and the glazing are connectable regardless of how the mounting of the glazing is designed.

In one embodiment variant, the second fastening element can be connected to the frame holder of the cabin by means of holding means. One of the advantages of the invention is that the second fastening element of the connecting member is subsequently attachable to existing cabins. A security of the glazing means of the first and second fastener and the connecting element is thus possible with different types and types of cabins. When Holding means can be screws, bolts, rivets, etc. use. As a holding means can also serve a welded connection. The second connection element may be an integral part of the cabin.

In another embodiment, the one end of the connecting element as an integral part of the cabin is inextricably linked thereto. One of the advantages of the invention is that the connecting element is directly connected to the cabin, for example, in that the connecting element is bolted to the cabin, welded, pressed, riveted or connected with pins. A screw can be secured in known ways, so that there is a permanent connection. The connecting element can, for example, be connected to the cabin by having a thread on the one sleeve or sleeve of the cable section.

In a further embodiment, the fastening element has a recess for receiving the one sleeve of the cable section, wherein the cable section can be guided by a peripheral recess and / or a hole. One of the advantages of the invention is that the fastener can be mounted by this embodiment on both flat, as well as curved or uneven surfaces. The recess ensures that the cable section is permanently held after mounting the fastener on the intended surface.

In one embodiment, the first fastening part is formed with a recess for receiving the one sleeve of the cable section and a peripheral recess for receiving the cable section. One of the advantages of the invention is that the overall height of the attachment part is substantially dependent on the diameter of the sleeve and As a result, a flat design of the fastening part is possible. In a further embodiment, the length of the recess is greater than the length of the sleeve. This has the advantage that the thermal expansion of the glazing and / or the cabin can be compensated by the sleeve is slidably held in their length in the recess. Thermal expansion means the change in the geometric dimensions (length, area, volume) of a body caused by a change in its temperature.

In another embodiment variant, the fastening parts are made of light metal and are provided on the glazing surface facing at least partially with an elastic layer. One of the advantages of the invention is that the fasteners are made of stainless light metal, preferably aluminum, so that the payload of the cabin is only slightly affected. As an elastic layer is used made of plastic and / or rubber. On the one hand, this layer serves to seal the holes in the glazing. Another advantage of the elastic layer is that the holding means are thereby relieved and that the force acting on the first fastener force is distributed over the elastic layer on the contact surface between the glazing and fastener.

The FIG. 1 illustrates a designated by the reference numeral 1 inventive cabin. The cabin 1 shown in a view from the outside is used in particular for cabin, cable and / or gondola lifts. The cabin 1 can also be used in funicular railways, roller coasters or giant wheels. The cabin has an opening 2. In this opening 2, a glazing 3 is held. The FIG. 1 shows four connecting members 4, which are respectively connected to the glazing 3 and the car 1. On the outside of the cabin 1, the four fastening parts 433 of the connecting members 4 are visible in this view. The other components of the connecting members 4 on the inside of the cabin 1 are not shown here. The cabin 1 also has various smaller openings with glazings held therein. Polycarbonate is preferably used for the glazing 3, for example as a transparent pane or plate. The glazing is usually flat, slightly curved or spherically curved. Other materials may also be used unless their use precludes it.

The FIG. 2 shows an interior view of the car 1 and illustrates in detail a designated by the reference numeral 4 connecting member. The connecting member 4 comprises a first fastening element 43, a second fastening element 42 and a connecting element 45 connecting them. The first fastening element 43 comprises two fastening parts 431, 433. A fastening part is mounted on the inside of the cabin 1 on the glazing 3 and another fastening part on the outside of the cabin 1 to the glazing 3 and connected together by holding means 435,436. When Retaining means are preferably used screws and nuts, wherein the nuts may be part of the one fastening part. But there are also other holding means used. Instead of screws and long pins can be used, which are respectively pressed at the ends, so that the connection is insoluble. Between the glazing and each fixing part 431, 433, an elastic layer 432, 434 is preferably attached. This layer serves to ensure that a fastening part 431, 433 does not rub directly on the glazing 3. Friction would lead to material erosion in the glazing, which could negatively affect the connection between the fasteners 431, 433. The two fastening parts 431, 433 of a fastening element 43 clamp the glazing 3 by means of a screw connection. The resulting contact force causes in the elastic layer on both sides of the glazing 3 increased friction. If an exceptional situation occurs, for example a cable derailment, the resulting load is distributed to the respective fastening elements 43 on the bearing surface of the fastening parts 431, 433 and on the retaining means 435, 436 or 437, 438. The elastic layer is preferably made of rubber or an elastic, stretchable plastic. The attached to the inside of the glazing 3 fixing part 431 can also be completely covered with an elastic layer. The fastening element 43 can also consist of a single fastening part, with which the connecting element 45 is connected. In this case, a U-shaped rod can be used as holding means 435, 436, which is guided on the outside of the glazing 3 through holes provided in the glazing 3 and through the fastening part 431 mounted on the inside of the glazing 3. The ends of the U-shaped rod can be secured, for example, with pins, by compression or by means of threaded nuts. By the reference numeral 32, the holder is the Glazing 3 called. In FIG. 2 a glazing 3 held in a groove or groove by a rubber strip is illustrated. The glazing 3 sits flush in the holder 32. The glazing 3 is in FIG. 2 shown canceled. The fastening element 42 is fastened with holding means 425, 426 on the inside of the cabin 1. The connecting element 45 connects the first and the second fastening element 43 or 42.

FIG. 3 illustrates the fastener 43 and the connecting element 45 in an exploded view. The glazing, here in a broken representation, has the reference numeral 3. The glazing 3 is shown on the inside of the cabin 1. There are two holes provided through which holding means 435,436 can be passed. An elastic layer 434, for example designed as a disk or membrane and preferably made of rubber, is held between the glazing 3 and the fastening part 433. The fastening part 433 preferably has two holding means 437, 438. These are usually realized as threaded bushes with an internal thread and are connected to the fastening part 433 undetachably. On the inside of the cabin 1, an elastic layer is also placed on the glazing 3. In FIG. 3 this is designated by reference numeral 432. The elastic layer is preferably made of rubber. But there are also other elastic materials used. The fastening part 431 may be completely or partially surrounded by this elastic layer. But at least on the glazing 3 facing surface such an elastic layer is provided. Between the glazing 3 on the inside of the cabin 1 and the fastening part 431, the one sleeve 452 of the connecting element 45 designed as a cable section 450 is held. The cable section 450 is passed through an edge recess 4312 of the fastening part 431.

FIG. 4 shows a sectional view of the connecting member 4 with a first fastening element 43, a second fastening element 42 and a connecting element 45. The connecting element 45 is usually flexible and / or bendable. It is preferably made from a cable section 450. At least one end of the cable section 450 has a sleeve 451, 452 connected thereto. The connection can be made by pressing. The connection between the sleeve and cable section is thus permanent. The one sleeve of the connecting element 45 is held in the recess designated 4311 in the fastening means 431. The cable section 450 is guided through a peripheral recess 4312. The other end of the connecting element 45 is held by the second fastening element 42.

FIG. 5 illustrates the connecting member 4 in a side view and shows a section of the fastener 42. Section IV-IV is in the FIG. 4 shown. The second fastening element 42 has a recess 421 for receiving the sleeve 451 of the connecting element 45. The cable section 450 is passed through a hole or opening 422 in the fastening element 42, so that the in FIG. 4 not shown second end of the cable section 450 in the first fastener 43 can be held. The holding means 425, 426 are used to connect the fastener 42 to the car 1. As holding means screws are preferably used. The recess 421 is designed such that its length L is greater than the length of the sleeve 451. As a result, mechanical tolerances of the cab 1 and / or the glazing 3 can be absorbed. Changes in the dimensions of the glazing 3 and / or the cabin 1, which, for example, by the influence of temperature fluctuations can also be compensated. This compensation is made possible by a gap or clearance 4211, 4212 formed between the end faces of the sleeve 451 accommodated in the depression, so that the sleeve can move freely within certain limits along its length.

The FIGS. 6 . 7 and 8 illustrate further views of the connecting member 4 with a first fastening element 43, a second fastening element 43 and a connecting element 45. The section line VV in FIG. 6 is as a cut in FIG. 5 shown.

FIG. 9 shows an embodiment of the car 1 with an opening 2 and a glazing 3, which is held by attached to the car 1 and the glazing 3 individual brackets 321 in the opening. FIG. 9 illustrates two connecting members 4, each having a first and a second fastening element 43,42 and a connecting element 45. Each connecting member 4 is connected to the cabin 1 and the glazing 3. The area of the glazing 3 is smaller than the area of the opening 2.

FIG. 10 illustrates another embodiment of the cab 1 with a glazing 3 held in the opening 2 by a frame support 322. The fastening element 42 of the connecting member 4 can be fastened to the frame support 322 and / or to the cabin 1 and / or to the glazing 3. In the latter case, the connecting element 45 would be looped around the frame support and fastened to the fastening element 43. It can be seen that the fasteners 42,43 both inside and outside of the cabin 1 can be fastened.

FIG. 11 schematically illustrates a cabin 1 with an opening 2, wherein the glazing 3 covers the opening. The Glazing 3 may, for example, be glued to the cabin 1. In FIG. 11 four connecting elements 4 can be seen. With a crosshair, the center of the glazing 3 is shown schematically. In this case, the connecting members 4 are mounted so that the respective fastening elements lie with the center on a line.
