Abstract
An industrial truck (10, 20, Fig. 2 or 3) has at least one transparent pane (1). The transparent pane (1) is formed from a glass pane (2) having a film (3), which is made from a polymeric material and is applied to at least one side. The polymeric material may be polycarbonate or polyester. The transparent pane may comprise heating elements (4).
Description
1 2431191 * Industrial Truck Having A Transparent Pane The invention
relates to an industrial truck having a transparent pane.
Industrial trucks often have transparent panes in order to, for example, protect the operator against environmental influences. This may be an individual protective pane, which is arranged, for example, in the region of the mast, in order to protect the operator and parts of the vehicle against loads falling off. However, the entire driver's platform may also be completely surrounded by a cabin, which usually has two or more panes, in order to improve the operator's vision. Such cabins should not only be protected against the ingress of foreign bodies or dust but also against unfavourable environmental temperatures, such as severe heat or severe cold, and are therefore often provided with double glazing.
The panes used are therefore relatively resistant to breakage, for which reason, for example, single-pane safety glass is used. If, nevertheless, damage occurs, panes manufactured from this glass shatter into small splinters. If the vehicle is used for transporting foodstuffs, for example for transporting open fish in containers filled with ice chips, the occurrence of tree splinters needs to be avoided under all circumstances since otherwise large amounts of the goods would be unusable.
Panes made from polymeric materials, in particular from polycarbonate, which has good breaking strength, is easy to process and has practically no shattering, are therefore also widely used in industrial trucks.
However, this material is also relatively expensive and has poorer visual properties and markedly reduced rigidity compared to conventional glass.
The latter factor means that the pane is subjected to severe vibrations during operation, which considerably impairs vision.
If the panes are equipped with heating elements in order to prevent them from fogging, in particular when there is a change from a cold to a warm environment, the heating of a polymeric pane results in a change in * the visual properties, with the result that the operator can perceive things behind the pane only unclearly and in distorted form. In addition, the rigidity of the pane is further reduced by the heating, which further increases the sensitivity to vibrations. Overall, the safety of the vehicle is thus impaired and/or productivity reduced.
The invention is therefore based on the objective of providing an industrial truck having a transparent pane, which can be produced in a simple and cost-effective manner and with which the occurrence of free splinters in the event of damage is prevented.
This object is achieved according to the invention by the fact that the transparent pane is essentially formed from a glass pane having a film, which is made from a polymeric material and is applied to at least one side. In this case, the film is understood to be any layer which is preferably applied to approximately all of the area of the glass pane and whose thickness is substantially less than that of the glass pane, a maximum of 1 / 10 of the thickness of the glass pane. In particular, these include layer materials applied as a film and coatings which are applied, for example, by spraying or dipping. Such a pane can be produced in a simple and cost-effective manner and has a rigidity which is similar to that of a simple glass pane. The polymeric material is considerably more extensible than the glass and thus remains intact in the event of the glass being damaged by the influence of a foreign body. The bond between the glass and the polymeric material prevents splinters from being set free when the glass is damaged since these splinters remain on the polymeric material layer.
In one particularly advantageous embodiment of the invention, the film is applied to both sides of the glass pane. This further improves sôfety since not only the breaking strength of the pane is overall improved but also splinters are prevented from coming free, as is possible in the case of a one- sided polymeric layer owing to splinters detaching on one side, for example in the event of damage at certain points, in a more reliable manner.
* The film is expediently essentially formed from polycarbonate. This material is particularly suitable in terms of its properties, in particular the mechanical and chemical properties, as well as its good processability.
In one further expedient embodiment of the invention, the film is essentially formed from polyester. This material is also particularly suitable in terms of its properties1 in particular the mechanical and chemical properties? and its processability, and is particularly costeffective.
It is furthermore expedient if the film has a thickness of from 25 to 500 micrometers, in particular of 80 - 200 micrometers. This makes possible good visual and mechanical properties, in particular the desired shatterproofness and strength, and simple production.
The glass pane and/or the film advantageously has a tint and/or colouring. This improves the visual conditions for the operator and prevents dazzle effects in the case of an unfovourable light environment.
It is also advantageous if the glass pane is formed from single-pane safety glass. Single-pane safety glass has high strength and rigidity, can be produced in a cost-effective manner and is available in many forms.
It is particularly advantageous if the pane comprises heating elements, in particular heating wires and/or preferably heating conductors applied by means of screen printing. As a result, the pane can be heated, and the condensation on the pane can be prevented or reduced when there is a change from cold to warm regions, i.e., for examples when travelling from a cold store to a warm environment. In comparison with a heated polymeric pane, substantially better visual properties are achieved without the mechanical properties being substantially impaired. Heating wires con easily be introduced into glass panes and are thus protected against environmental influences. Using screen printing, heating elements can be applied in a simple and cost-effective manner, even in the case of complex geometries.
* It is expedient if the heating elements are arranged in the region of the boundary surface between the glass pane and the film. They thus lie in the vicinity of the surface of the pane and have a particularly good heating effect. In addition, the production of the pane is particularly simple.
In one expedient embodiment of the invention, the transparent pane is arranged in the region of a mast of the industrial truck. In this region, the transparent pane is particularly advantageously arranged in the form of protection against a load falling off, and good vision for the operator is particularly important.
The transparent pane is expediently part of the cabin glazing, in particular double glazing. Glazed cabins offer optimum protection for the operator, in particular against heat and/or cold, but also present a severe risk in terms of shattering. The pane according to the invention therefore offers particularly great advantages.
It is also advantageous if the transparent pane has a surround on at least one edge. This prevents splinters from coming free at the edge.
Further advantages and details of the invention will be explained in more detail below with reference to the exemplary embodiment illustrated in the drawing. Identical parts are given the same references. In the drawing: Figure 1 shows the basic design of the transparent pane of an industrial truck according to the invention; Figure 2 shows a reach fork truck having a transparent pane arranged on a mast, as an example of an industrial truck according to the invention; and Figure 3 shows a reach fork truck having an enclosed, glazed driver's cabin, as an example of an industrial truck according to the invention.
Figure 1 shows a schematic of the design of the transparent pane 1 of an industrial truck according to the invention. A central glass pane 2 made from conventional single-pane safety glass is coated on both sides with a film 3 made from polyester. The films 3 have a thickness of 175 j.tm and are * applied to the glass pane 2 by means of methods from the prior art, such as adhesive bonding. Heating elements 4 are arranged on the surface of the glass pane 2 and are applied by means of screen printing in the exemplary embodiment shown. In the edge region 5, the glass pane 2 is surrounded by a mounting 6 which is configured as a rubber seal.
If a foreign body hits the pane 1 with such a force that the glass pane 2 breaks the splinters are held together by the polyester films 3. Owing to the film 3 on both sides, the splinters are reliably prevented from detaching. even when, for example, a pointed object hits the pane 1, which object would not lead to destruction of the glass pane if the latter were unprotected or provided with a film 3 only on one side, but would mean that one or more small splinters would break free. The rubber seal 6 prevents splinters from emerging in the edge region 5.
Figure 2 shows a reach fork truck 10 having a protective pane 12 arranged on a mast ii, as an example of an industrial truck according to the invention. In the case of the truck 10 shown, a load is received and lifted by the fork-shaped load-receiving means 13. In addition, it is possible for the load-receiving means 13 to be displaced in the horizontal direction. In order to protect the operator on a driver's platform 14 against objects falling off and from harm caused by the vertical movements of the load-receiving means 13 and/or the mast 11. the protective pane 12 is arranged at the front of the driver's platform 14. In the case of vehicles according to the prior art, such a protective pane is usually formed from polycarbonate and has the disadvantages explained, in particular as regards vibrations of the pane. In the case of the vehicle 10 according to the invention shown, the protective pane 12, as shown in Figure 1, is formed from a glass pane 2 made from single- pane safety glass and a film 3 on two sides made from transparent polyester having a thickness of, in each case, 175.tm. Heating elements 4 are applied to the surface of the glass pane 2 on the driver's side, as shown in Figure 1,it not being possible for the heating elements 4 to be shown in the * present figure. As a result, the protective pane 12 can be heated and the condensation on the pane is prevented when there is a change from a cold to a warm environment. The protective pane 12 is surrounded by edging 15 made from a polymeric material (but could also be manufactured from a suitable metal), as a result of which the relatively sensitive edges are protected and the emergence of splinters in the event of breakage of the protective pane 12 is prevented in this region.
Finally, Figure 3 shows a reach fork truck 20 having an enclosed driver's cabin 21. This vehicle 20 is identical in terms of its basic design to the reach truck 10 shown in Figure 2, but has a driver's cabin 21 which is glazed on all sides. The cabin 211s completely provided with doubleglazed panes 22 according to the invention. In this case, the film according to the invention is expediently only arranged on the respective outer side of the twin-pane 22, since an emergence of splinters in the intermediate area between Iwo panes 22is not critical in terms of safety. In particular in the case of the severely bent pane 22a on the rear of the vehicle 20, the glazing according to the invention offers significant advantages compared with the prior art, since, for example, large, bent polycarbonate panes can only be produced with difficulty and at considerable cost and have poor visual properties. This exemplary application prevents the emergence of the splinters at the edges of the glass panes 22 through the frame components 23 of the cabin 21. into which the panes 22 are fitted. The pane 22b according to the invention, which is fitted in the roof region of the cabin 21, has a polyester film on one side with a slight tint, in order to prevent the operator from suffering from dazzling effects when looking upwards. i.e. into the sky or a bright workshop light.
It goes without saying that other embodiments are also conceivable for the pane 1, for example with coatings which have in each case different thicknesses on both sides of the pane 1 or are produced from a different material. In addition to tinting of the glass pane 2 and/or the film 3.
* depending on the application case the use of other glasses for the glass pane 2, for example composite safety glass, is likewise conceivable.
Furthermore, only individual elements of the glass elements 22 can also be formed according to the invention in the glazing 22 of a vehicle cabin 21; this depends on the stresses to be expected and the requirements as regards transparency of the regions. For example. individual glass elements may also be provided with a film 3 according to the invention on both sides, and other glass regions only with a film 3 according to the invention on one side, since these regions are at less risk of breakage, for example, and splinters detaching in the direction of the uncoated side is non-hazardous. In the case of double glazing comprising two panes I according to the invention, the polymeric layer 3 in the case of one or both panes 1 may also be arranged in each case on the side pointing towards the intermediate space between the panes 1, as an alternative to the above-described design, depending on operational requirements. with the result that this side is protected against mechanical stress, in particular against scratches. Furthermore, the surround for the pane I may also be formed from, for example, metal or from a polymeric material.
