Description

The This invention relates to gates that are located in passageways or main entrances of industrial warehouses, Garages and the like. Available to allow people to pass through without that this to open the entire gate is; These gates are usually be referred to as "passage doors" and become in the remainder of this description therefore designated by this term.

It must also be pointed out that although the gates or passageways, the below considered are louvered gates, that is, divided gates, i. consisting of Panels or panels hinged together horizontally are and vertically along guides slide in the walls to disposal so that they are similar to one Raised catch and can be lowered the invention can also be applied to normal or pivoting gates can.

Currently exist the passage doors off closures or flaps or wings, which are fixed at the gates by means of hinges, similar to those from usual Front doors; this solution is easy and cheap, but has some disadvantages.

one of these consists in the fact that the hinges protruding outward fixed or mounted by means of screws or rivets are: they are therefore visible and (in addition to being not aesthetic are inevitably atmospheric agents and other external factors exposed as punches and etc .; in this context must be considered be that in industrial applications, such as those typical of louvered gates, the passageways often Subject of punches as a result of imprecise maneuvers of lifters, forklifts and the like are.

One Another disadvantage of the passage doors, which are known so far, is the reliability their closing activity. Of course must be on it be noted that in general industrial doors and passage doors through plates of a sandwich type are formed, i. consisting of a layer of insulating Material (usually expanded synthetic resin or mineral wool), which is a has low structural strength and between two external ones Sheet metal or sheet metal sides is arranged, to which the (with screws or rivets) hinges are fixed.

These Type of structure is lightweight and has good insulating properties, However, it is not very stiff or rigid, so that with the Time the plates of the passage door deformed or a game can be affected; in such cases becomes the closing activity the door is defective or defective.

It should about it be noted that the Stiffness of the panels within the gates is a significant requirement in particular in the case of lamellar gates during each opening and closing cycle they are subjected to stresses or strains caused by their movement and through the transition from a vertical position to a horizontal position, and vice versa are effected.

As an example, refers EP 1 108 849 on a passage door disposed in a louver gate, where the passage door comprises a plurality of panels which are hinged to corresponding plates of the louver gate so that the door can be opened in one position which the louver gate is arranged substantially in a vertical or horizontal plane.

US 4,461,120 refers to an improved porthole assembly in one movable gate to allow passage therethrough when the wall opening is covered, wherein the gate at least one primary goal plate which is movable to substantially cover the wall opening, and the passage gate has a first side edge coincident with the first one Torplatte hingedly connected.

The The present invention is directed to this prior art to improve, namely, namely or in particular to the goal or object has, a passage door for gates structural and operating features to disposal to ensure efficient and regular closing over time.

This Aim is achieved by an access door that has the features as disclosed in claim 1, wherein the door leaf by one or more plates is formed on the plates or Panels of the lamellar door is hinged or are, which thereby is characterized in that they having a first and a second portion corresponding to along the hinged edges of the panels of the door and the door panel is determined, and fixed at the ends of hinge or hinge blocks Are mounted, which are in engagement with the sections, which are suitable to form corresponding parts of the hinges.

In this way, the sections or sections provide the necessary rigidity of hinged or hinge edges of the plates or Panelle of Door and the door panel, ie their most stressed zones, while the end blocks ensure a stable and secure mounting of the hinges as a result of their engagement with the sections.

According to one preferred training, the end blocks are configured so as not to from the profiles of the cuts protrude, causing them to protect the hinges by the cuts against external shocks to disposal put.

In accordance in another preferred embodiment, the passage door comprises a third one and a fourth section, which are each identical to the second and the first section and which along the closing edges or margins of the door leaf and the louver gate are arranged like the preceding ones.

Also in this case are endblocks at the ends of the cuts that are engaged with their central section, and for which is intended to form the stop element for the door leaf against the gate.

These and other characterizing features of the invention will become apparent the description will become clearer, provided below which focuses on a preferred but not exclusive education which is illustrated in the accompanying drawings, in which:

1 a perspective view of a laminated gate with a passage door according to the present invention;

2 and 3 the detail that goes through the circle in 1 indicated in corresponding operating conditions;

4 and 5 show the top and bottom hinge blocks;

the couple of 6a . 6b a cross-section through the hinged or hinge edge of the passage door in 1 in the closed state and during opening, respectively;

7a . 7b a cross section through the closing edge of the passage door in 1 in the closed state or during opening;

8th and 9 show the blocks that run along the closing edge of the door in 1 available;

10 the blocks in 8th and 9 in the closed state of the gate of 1 shows.

The first figure shows a total of a Lamellentor 1 , which is a series of panels 2 . 3 . 4 . 5 and 2 ' . 3 ' . 4 ' . 5 ' which are hinged together horizontally, the upper and lower edges of which are respectively formed with the typical convex and concave profiles known in the art and fall prevention standard to prevent people from accidentally placing their fingers between them the plates of the gates during an opening and closing of the latter get caught or caught.

Some Examples of these cuts or sections are in the European Patent EP-A-1 213 429, assigned by the same applicant how the present invention was deposited.

In the gate 1 there is an access door 10 whose door leaf through a series of panels or panels 12 . 13 . 14 . 15 is formed, which are horizontally hinged together and which have the same height as the plates of the laminated gate; the upper and lower edges of the panels 12 - 15 have the above-mentioned female and female profiles.

In order to allow the door panel to be mounted on the door, corresponding sections are made along the hinging and closing edges of each panel 12 - 15 mounted or attached; More specific in accordance with a preferred embodiment of the invention are the sections extending along both edges of the plates 12 - 15 be mounted, identical to each other and are with 16 designated.

In the same way are the cuts, which on the plates 2 - 5 and 2 ' - 5 ' of the gate were fixed, identical to each other and are with 18 designated.

The cuts 16 have an open cross section, which, as in 6a . 6b can be seen, with the hinge edge of the plates 3 and 13 shown is a front flange 20 on the outside of the gate 1 and a rear flange 21 on the inside, passing through a central section 22 are connected.

The front flange 21 has a rounded configuration for the reasons that will be more apparent below, while the rear flange 21 is substantially flat or flat and an engaging or intervention level 24 having; the central section 22 extends along the end of the plate 13 and defines a seat inside 26 which is closed in this case.

As mentioned above, is a section 16 at the closing edge of the plates 12 - 15 set; with reference to 7a . 7b It can be seen that this portion is disposed in a symmetrically opposite position with respect to the corresponding portion which is on the hinge side of the same plate 13 is arranged.

Regarding the cuts 18 which on the plates 2 - 5 and 2 ' - 5 ' of the slat or sectional door 1 They can also have an open cross-section with a front flange 30 , which is shaped in a rounded manner, a flat rear flange 31 and a central section 32 exhibit; two parallel guides 35 are also provided on the latter and are functionally equivalent to the closed seat 25 which has already been seen, as will become clearer below.

The cuts 16 and 18 are fixed to the corresponding plates by means of screws or rivets (not shown in the drawings), which by their rear flanges 21 and 31 pass; To ensure an improved sealing effect of the attachment, seals may also be attached to the contact points between the sections and the surface of the plates.

An articulated connecting or hinging of the door leaf 10 and his plates 12 - 15 with the gate 1 is done using four endblocks 41 . 42 . 43 . 44 executed, which at the upper or bottom ends of the cuts 16 respectively. 18 (please refer 2 ) are attached; these blocks are separate in 4 . 5 shown and in terms of their matching shape is only a pair of blocks 41 and 42 described in detail since the other two blocks thereof differ only in the part relating to the hinge.

Like this in 5 can be seen comprises the first block 41 a front element 50 , a backward element 51 and a vertical plate 52 which is meant to be in the seat 25 of the section 16 intervene; the base 53 the plate 52 is formed with a profile which coincides with that of the edge of the plate on which the block 41 is attached; therefore, since in this case the block is associated with the bottom edge of the plate, it is the base 53 shaped according to the concave profile thereof, which allows coupling with the convex profile of the upper edge, to prevent accidental trapping of fingers between the plates, as already mentioned above.

The front element 50 has a collar at the top 55 within which the section 16 is inserted and where a hinge sleeve 56 is trained; the block 41 is at the plate 13 fastened using screws or rivets (not shown) attached to the rear element 51 are applied.

The other soil block 43 differ from the previous block in that it has a hinge pin 57 ' having formed thereon; because of this are in 5 the parts of the block 43 in the same way as those of the block 41 designated or numbered, with the addition of a stroke. It should also be noted that the plate 52 ' in the guides 35 of the cuts 18 engages in a manner which is completely equal to that of the plate 52 with the seat 25 is.

4 shows the upper blocks 42 and 44 which, like the floor blocks, is a front element 60 ( 60 ' ), a backward element 61 ( 61 ' ) and a vertical plate 62 ( 62 ' ) exhibit; however, they have these blocks with the convex top of the panels 2 - 5 and 12 - 15 are associated with an approach 63 ( 63 ' ), extending from the opposite side to the plate 62 ( 62 ' ) formed with a convex profile matching that of the edge of the plates. Further, the upper blocks 42 . 44 also together by means of a sleeve 66 and a pin 67 ' hinged.

The cuts 16 and 18 that run along the closing edge of the plates 12 - 15 . 2 ' - 5 ' are arranged with blocks 71 . 72 . 73 and 74 coupled, which are similar to those considered, but have no hinge.

These blocks can be in 8th - 10 and in view of their similarity with other blocks, they do not require any special explanations; the reference numerals of their parts correspond to those already seen, with the addition of 30 units (thus 50 80 . 51 becomes 81 . 60 becomes 90 etc.).

From the previous explanations is the principle of operation of the passage door 10 easy to understand. During opening and closing of the louver gate is the door leaf 10 that through the plates 12 - 15 is formed, closed; for this purpose it is equipped with a key operated lock in 1 is visible or provided with handles or other equivalent means.

In this situation are the cuts 16 on the hinge and closure edges near the sections 18 arranged like this in 6a . 7a shown, and the gate 1 together with the door leaf 10 forms a single body.

Therefore, the rotation or the pivoting occurs ( 3 ) with respect to the horizontal hinge axis of the plates 2 - 5 and 2 ' - 5 ' the former integral with that of the plates 12 - 15 the latter during a raising and lowering of the gate.

The door leaf 10 the passage door 10 On the other hand, it is opened and closed in a precise and secure manner (by operating its key, handle or the like) due to the effect that the cuts 16 and 18 showing the edges of the panels 2 - 5 . 2 ' - 5 ' . 12 - 15 stiffen, and fixing the hinge blocks 41 - 44 with which they by means of the plates 52 . 52 ' . 62 . 62 ' are coupled. In other words, the cuts work 16 the plates 12 - 15 and the blocks 41 . 42 . 71 . 72 associated with it, as a single frame that stiffens the structure of these plates.

Similarly, the cuts work 18 on the plates 2 - 5 . 2 ' - 5 ' the lamellar gate are arranged in the manner of peat setting; The result is therefore that a stable and reliable closing and opening of the door panel 10 are ensured over time.

It There are also other beneficial effects passing through the passage door of the previous one Example can be achieved.

First, it is obvious that the use of interchangeable sections along the hinge and closure edges of the panels 12 - 15 . 2 - 5 and 2 ' - 5 ' allows production costs to be kept low, as it requires only two types of cuts (rather than four, as is usually the case).

Second, it must be noted that coupling the hinges to the sections 16 and 18 ensures a rigid entity and protects it against damage due to knocks and the like.

In fact, these are coupled sections and hinge blocks 41 . 42 . 43 and 44 preferably made of a suitable metallic material, such as aluminum, or a strong plastic; therefore, in the event of any impact of the door by a vehicle or any other object which generally damages the panels, the hinge blocks in each case remain in registry with respect to the sections, ensuring that the passage door remains operable.

It should also be noted that, since the shape of the sections or sections 16 . 18 a continuation of that of the hinge blocks 41 . 42 . 43 and 44 The latter are subjected to less impact because they do not protrude from the rest of the panel or panel.
