Definitions
- the present invention refers to a folding door composed of one more pairs of leaves, both pairs with the two leaves hinged to each other and one of the leaves hinged to the frame of the space to be closed.
- Doors of the type meant, used for example to close cupboards and the like, are supported on one side by hinges between one of the leaves and the frame, and on the other by guide elements which are attached to the inner surface of the other door leaf, matching its upper and lower external corners, and sliding on rails placed along the upper and lower sides of the frame of the space where the door is mounted.
- These guide elements generally consist of a bushing in which is a core which can turn and move axially, said core being pushed out of the bushing by a spring.
- the core forms a sliding shoe on its outside end which slides on the corresponding rail.
- the hinges acquire a play which results in the doors falling slightly, from their original position, possibly even touching the lower rail with the lower edge as the door is closed.
- the object of the invention is to eliminate the problems mentioned, so that a proper working of the door is ensured throughout its lifetime, with no risk of rubbing between the door leaves and the lower rail.
- Another object of the invention is to ensure the relative positions of the door at the time of assembly, by a construction and arrangement of the hinges which connect the leaves, so that a maximum opening is achieved.
- the core of the guide elements comprises two consecutive coaxial cylindrical segments of different diameters, of which the smaller one ends in the guide shoe.
- This smaller diameter segment has a projection on its side which makes an axial lever directed towards the segment of greater diameter.
- This lever is defined by a plateau parallel and next to the segment of greater width and by two helical ramps of decreasing width, which go from said plateau in opposite senses towards the shoe.
- the projection which makes up the lever is placed so that the aforementioned plateau occupies an angular position agreeing with the rails on which the guide shoes slide.
- the guide element bushing has a pin which projects internally and rests on the cylindrical surface of the segment with a smaller diameter core, between the lever and the segment of greater diameter. This pin limits the outwards motion of the core and constitutes a support element for the bushing on the core lever whenever there are deviations or vertical displacements of the door during its opening and closing with respect to its original position.
- nucleus starting from the free base of the greater diameter segment, has a blind hole inside which is partially housed the spring which shall push the core outwards.
- the core In the larger diameter segment the core has two diametrically opposite grooves which are accessible through openings made in the guide element bushing.

Abstract
Description
- The present invention refers to a folding door composed of one more pairs of leaves, both pairs with the two leaves hinged to each other and one of the leaves hinged to the frame of the space to be closed.
- Doors of the type meant, used for example to close cupboards and the like, are supported on one side by hinges between one of the leaves and the frame, and on the other by guide elements which are attached to the inner surface of the other door leaf, matching its upper and lower external corners, and sliding on rails placed along the upper and lower sides of the frame of the space where the door is mounted.
- These guide elements generally consist of a bushing in which is a core which can turn and move axially, said core being pushed out of the bushing by a spring. The core forms a sliding shoe on its outside end which slides on the corresponding rail.
- During the use of the doors the hinges acquire a play which results in the doors falling slightly, from their original position, possibly even touching the lower rail with the lower edge as the door is closed.
- In addition, in traditional doors the hinges which connect the two leaves are generally placed with the turning axis identical to the line of separation of the leaves, for which reason, together with the proximity of the two leaves, full opening is not achieved.
- The object of the invention is to eliminate the problems mentioned, so that a proper working of the door is ensured throughout its lifetime, with no risk of rubbing between the door leaves and the lower rail.
- Another object of the invention is to ensure the relative positions of the door at the time of assembly, by a construction and arrangement of the hinges which connect the leaves, so that a maximum opening is achieved.
- In order to achieve these and other objectives, according to the invention the core of the guide elements comprises two consecutive coaxial cylindrical segments of different diameters, of which the smaller one ends in the guide shoe. This smaller diameter segment has a projection on its side which makes an axial lever directed towards the segment of greater diameter. This lever is defined by a plateau parallel and next to the segment of greater width and by two helical ramps of decreasing width, which go from said plateau in opposite senses towards the shoe. The projection which makes up the lever is placed so that the aforementioned plateau occupies an angular position agreeing with the rails on which the guide shoes slide.
- In addition, the guide element bushing has a pin which projects internally and rests on the cylindrical surface of the segment with a smaller diameter core, between the lever and the segment of greater diameter. This pin limits the outwards motion of the core and constitutes a support element for the bushing on the core lever whenever there are deviations or vertical displacements of the door during its opening and closing with respect to its original position.
- In addition the nucleus, starting from the free base of the greater diameter segment, has a blind hole inside which is partially housed the spring which shall push the core outwards. In the larger diameter segment the core has two diametrically opposite grooves which are accessible through openings made in the guide element bushing.
- The characteristics described, as well as others characteristic of the invention, are described below in greater detail with the aid of the attached drawings in which a non limiting embodiment example is given.
- In the drawings:
- Figure 1 is a front elevation of a two-leaf folding door according to the invention.
- Figure 2 is a cross section of the door along the II-II line of figure 1.
- Figure 3 is a section similar to figure 2, with the door open and the leaves attached.
- Figure 4 is a cross section of one of the hinges which connect the two leaves of the door.
- Figure 5 is a front elevation of the lower guide element with the door open.
- Figure 6 is a vertical cross section of the lower guide element along the VI-VI line of figure 5.
- Figure 7 is a view similar to figure 5 of the upper guide element.
- Figure 8 is a vertical cross section of the upper guide element along the VIII-VIII line of figure 7.
- Figure 9 is a perspective view of the core of the guide elements for the outer leaf of the door.
- Figure 10 is a lateral elevation of the core of figure 9.
- Figure 11 is a cross section of the core along the XI-XI line of figure 10.
- Figure 12 is a diametrical cross section of the core along the XII-XII line of figure 10.
- Figures 13 and 14 are views similar to figures 10 and 12 respectively, showing a variation of the core.
- Figures 15 and 16 show the lower guide element with the door closed and open, respectively, with the core shown in cross section as in figure 11.
- Figure 1 shows a rear elevation of a folding door with two leaves, 1 and 2, which are jointed to one of the vertical sides of
frame 3 byhinges 4 with a restoring spring, of known construction. The two leaves are also jointed to each other byhinges 5. Theouter leaf 1 has, on its inner side and matching the upper and lower outer corners,guide elements upper rails frame 3. - In the closed position leaves 1 and 2 of the door are in a coplanar position as seen in figure 2.
- Hinges 5 which connect
leaves blades rings 12 through which the jointing axis passes. According to the invention, one of the blades has alug 13 at the edge adjacent torings 12 of the joint axis, which projects out at a right angle on the connecting side of the door leaves, meant to be introduced betweenleaves - These hinges between the leaves are placed as seen in figure 3, with
leaves joint axis 12 of the hinge does not meet the inner edge of the two leaves. - With all of the above, when the door is opened
leaves -
Guide element 6 is shown in figure 5 withcorresponding leaf 1 in its open position. This guide orguide element 6 consists of acase 14 which extends upwards and sideways, in one direction, in aflap 15 with holes forscrews 16 to attach the door. As seen in figure 6,case 14 is connected to arecess 17 made inleaf 1 of the door in its inner face. -
Case 14 is open on the bottom, and houses acore 18 which is pushed outwards byspring 19. The core projects out fromcase 14 in an amount which makes up aguide shoe 25 which can slide oncorresponding rail 8. -
Case 14 has awindow 21 to the wall which meets the vertical free edge ofleaf 1.Case 6 also has atransverse pin 22 mounted, which is secant to the internal cavity which housescore 18, as is described below. -
Upper guide element 7, shown in figures 7 and 8, is of the same construction asguide element 6, as described with reference to figures 5 and 6, with the same labels used with a subscript "a" to indicate identical elements and components. - The configuration of
core 18 is described below with reference to figures 9 to 12. - This core is made of two cylindrical segments of different diameters labeled by
numbers Segment 24 of smaller diameter ends in slidingshoe 25, consisting of alower surface head 26 of approximately cylindrical shape, from which projects axially in a diametrical position alug 27 meant to enter thecorresponding rail - From the upper base of the
larger diameter segment 23, the core has a blind hole in which spring 19-19a, described referring to figures 6 and 8, will be partially housed. Inaddition segment 23 has two diametricallyopposite grooves 29 for the reason later described. -
Segment 24 of smaller diameter has aprojection 30 which as can be seen in figure 11, is limited by convergingsurfaces 31, tangent to the cylindrical surface ofsegment 24. Thisprojection 30 begins at thesliding shoe 25 and ends near thesegment 23. In the area closest tosegment 23 it makes aplateau 32 parallel and next to saidsegment 23 from which plateau start twohelical ramps 33 in opposite senses an inclined towards theguide shoe 25. -
Pin 22 described with reference to figures 5 to 8 shown in figure 9 acts as a stop to limit the outwards motion ofcore 18 of bushing 14. When the door is closedpin 22 is left betweenplateau 32 andsegment 23. When the door is open, as the bushing orcase 14 turns with the leaf the core and the pin will lie in the relative position shown in figure 9. - If for any reason the doors begin to fall slightly from their original position, during the opening stage stop 22 of the guide element case, as
core 18 turns, due to the door dropping will slide on one oframps 33. When the door is being closedpin 22 shall also slide alongramp 33 upwards, forcing the leaves of the door up and so preventing the lower edges from rubbing againstlower rail 8. - When the leaves reach the fully closed
position pin 22 will rest onplateau 32, thus ensuring the closed position of the door. - If for any reason one of the leaves were accidentally lifted during the opening or closing the same process described above would take place in the opposite direction.
-
Grooves 29 ofsegment 23 of the core are accessible through window 21-21a of the case or bushing of the guide elements to facilitate positioning the core during assembly of the doors. -
Projection 30 described above, along withupper plateau 32 andramps 33 define a lever to ensure the correct functioning of the door leaves, even if there is a play in the hinges. - Figures 15 and 16 show the relative position of
pin 22 andprojection 30 ofsegment 24 of the core, in the closed door position, figure 15, and open, figure 16. - Figures 13 and 14 show a variation of execution of the core in which the shoe consists of a rolling
element 35 mounted on anotch 36 made on thelug 27 which in this case projects directly from the lower base ofsegment 24 of the core, in a diametrical position. The lug will enterrail 8, while the heads of rollingelement 35 shall rest on and roll on the upper flaps of therail 8 profile. Otherwise the core shown in figures 13 and 14 is identical to that described in figures 9 to 12.
