Abstract

The invention relates to sliding doors, and more especially to those intended to be fitted inside dwellings. To facilitate the transport and assembly of sliding doors, it is proposed to first produce a rigid monobloc metal structure based on profiles comprising two vertical uprights (14, 16) two intermediate uprights (24), a threshold bar (22) and a lintel (18). The profiles corresponding to this structure are spaced from each other so that the door (12) can be introduced into the structure on the side which will form the door frame. The door is suspended by bolts (38) screwed into mobile carriages (38) moving in a suspended slide (20). Notches (46) closed by a metal plate are provided at the top of the door to secure the door to the bolts.

  REMOVABLE SUSPENDED SLIDING DOOR

  The invention relates to sliding doors, and more particularly those which are intended to be

  mounted inside the dwellings.

  Sliding doors have the advantage over pivoting doors of consuming less living space. The pivoting space of the pivoting door must indeed be reserved, while the sliding door occupies only its own volume even during

open it and close it.

  Sliding doors are particularly suitable for small dwellings such as studios

or two pieces.

  However, these doors pose a problem of

  transport and a mounting problem.

  It is known that the pivoting doors are prepared at the factory with their frame, so that the dimensions of

  the door are exactly adapted to those of the frame.

  They are transported mounted in their frame, in the closed position, and the door gives sufficient rigidity to the assembly during transport; there is no deformation of the frame thanks to the presence of the door.

  It is not the same for a sliding door.

  Indeed, the part that can be called "dormant" in the case of a sliding door should include both the frame of the door (doorframes, lintel, threshold bar) and the embedded structure in which the door slides when it arrives in open position. As a result, the frame is generally twice as large as the frame of a pivoting door; it is therefore already more difficult to transport; and above all, the door gives no rigidity to the frame, whether in the open or closed position. On the contrary, its weight is not distributed over the entire structure and tends to deform the whole. It is therefore practically neither advantageous nor even possible to transport the complete structure pre-assembled at the factory. The other problem is that of editing. Since we can not stall in place a set of one mounted factory, there are inevitably problems of implementation, adjustments, rectifications, which ultimately make the whole expensive as a result of the artisanal labor that is needed. It would therefore be desirable for most of the structure to be prefabricated at the factory and for manufacturing to be as small as possible or as easy as possible for assembly operations.

on the spot.

  One of the aims of the invention is to propose an industrial solution in which a rigid structure forming the frame is completely manufactured in the factory and transported to the place of installation, the door being transported separately from the frame and being mounted in the frame once. the sleeping frame installed in its final place. If one manufactures a rigid structure in one piece which does not include the door, it is then necessary to solve at the place of the installation the problem of the insertion of the door in the structure. This problem is not an easy problem considering the respective dimensions of the door and the structure that must receive it. One of the aims of the invention is to propose a construction facilitating the insertion of the

  door in the prefabricated frame structure.

  Among the other problems that the present invention aims to solve, it is possible to mention the possibility of later removing the door to carry out repairs on the door or on the structure. In an embodiment already devised by the Applicant, the door is inserted into the structure of the side which is embedded in a fixed partition; then, this recessed side is covered with a wall covering (plasterboard and cladding). Therefore the door does

  can no longer be removed without destroying the wall cladding.

  The invention proposes a solution in which the door is inserted into the structure on the side of the door frame, that is to say on the side of the free space which will be opened and closed by the door in operation. The invention has several aspects, each of which is of importance, without the invention being considered as limiting the combination of these various aspects; these aspects include: - an upper slide in which can slide a carriage which is suspended the door; a suspension of the sliding door to a mobile carriage by means of a support piece fixed on one side to the upper part of the door and on the other side to the carriage, the hooking between the door and the door; a support piece that can be made laterally when the door is laterally introduced into the frame; - a suspension of the sliding door to a movable carriage by means of a bolt whose head is down and whose rod, facing upwards, is screwed into the carriage, the rotation of the bolt head allowing a height displacement of the head relative to the carriage and the hooking of the door being through the bolt head so that the door can be raised more or less by screwing the bolt; - An attachment means on the upper part of the door, constituted by a notch in the door, this notch having a lateral opening and being closed at its upper part by a plate having itself another notch open laterally and dimensions smaller than the notch of the door, so that a means of suspending the door (such as a bolt) can be introduced laterally into the notches and can then allow the door to be raised through the door. closing plate of the notch of the door; - Another important aspect of the invention is the constitution of the rigid frame of the structure with at its upper part (lintel) a section of particular section. The general section of the profile is chosen on the one hand to ensure sufficient mechanical strength and on the other hand to ensure an aesthetic of the lintel of the door where the lintel is visible; here the profile is more widely open on the side where we must introduce the door on the opposite side. After mounting the door the frame profile is too narrow to hide the top of the door; we then report another profile, which can also hold by simple interlocking, in front of the top of the door, to hide it. Likewise, the vertical uprights of the rigid frame are more widely spaced from each other on the side where the door must be introduced, and additional masking profiles are provided to reduce the width of the door opening to a value compatible with a closure

  correct opening through the door.

  According to the invention there is provided, mainly but not exclusively, a sliding door assembly comprising a rigid frame structure forming both the door frame in the open position and a concealed housing for the door in the closed position, this structure comprising an upper slide in which is slidable at least one movable carriage, characterized in that the assembly comprises a support piece adapted to be fixed on one side to the carriage and the other to the sliding door, this part to suspend vertically the door to the carriage and move the door with the carriage when the carriage moves in the slide, and in that the door has at its upper part a notch cooperating with the support piece so as to allow a lateral positioning of the attachment means with respect to the

support piece.

  The support piece will preferably be a bolt screwed into the carriage, and the hooking means (cooperating with the bolt head) will preferably be a notch system with lateral opening, closed at its upper part by a plate itself. even slotted

laterally.

  Other features and benefits of

  the invention will appear on reading the description

  following which is made with reference to the accompanying drawings in which: - Figure 1 represents a general view of a

  sliding door installed in a partition.

but for the lintel of the door.

  To understand the context of the invention is shown in Figure 1 a general view of a door

  slider installed in a partition.

  The partition is in the plane of the figure and designated by the reference 10; it is schematized by crossed hatching. Parts of the structure that are concealed (because embedded in the partition) are

represented in dotted lines.

  The sliding door is designated by the reference 12; the mounting structure of this door essentially comprises a rigid (preferably metallic) rectangular frame whose surface (height x width) is substantially double the surface of the door 12; half of this frame is visible (in solid lines), the other half is embedded in the partition

(dotted lines).

  The frame comprises two vertical uprights, respectively 14 and 16 forming two vertical sides of the rectangle; it further comprises a lintel 18 and a threshold bar 22, forming respectively the two horizontal sides of the rectangle. Finally, the frame comprises two intermediate uprights, of which only one (reference 24) is visible in Figure 1, the other being masked by the first; these amounts extend in fact parallel to each other, vis-à-vis on both sides of the partition, substantially in the middle of the rectangular frame; they define between them a slot in which can slide the door. The space between one of the vertical sides of the rectangle and the intermediate uprights is the opening space that the door can close or leave free depending on its position (in Figure 1 is the space between the vertical upright 14 and the intermediate amounts); the space between the other vertical upright (16) and the intermediate uprights is embedded in the partition; in fact the partition at this place is constituted by the metal frame and by wall plates

dressing hiding this frame.

  The uprights and lintels are made essentially from metal profiles,

  preferably steel with a thickness of about 1 mm.

  FIG. 2 represents a general view of the metal structure forming the frame of the door according to the invention, as it is manufactured in the factory

  and transported to the place of installation.

  The structure forms a single block of parts integral with each other; it is preferably carried out by welding metal sections whose

  sections are shown briefly in Figure 2.

  The numerical references in this figure are the

same as in Figure 1.

  Preferably, to reinforce the rigidity of the one-piece structure in the part to be recessed, reinforcement bars 25, for example horizontal, are welded between the vertical upright 16 and the intermediate uprights 24, either on one side only or preferably on both sides of the structure. These reinforcement bars will also be used to support the plates

  wall cladding that will be laid later.

  The lintel 18 of the structure comprises a slide 20. This slide 20 extends continuously over almost the entire length of the lintel, both in the left part and in the right part (to be embedded) of the structure. This slide serves as a rail

  sliding to one or more moving carriages 26.

  In the left part, the slide is fixed to a profile always visible. In the right part she

  is attached to another non-visible, narrower profile.

  In the left part the slide is shorter than the visible profile so as to allow the setting

place carts.

  The trolleys can nevertheless be mounted permanently in the slide at the factory. In that case,

they are not repairable.

  To these carriages are fixed support pieces which will serve to support the sliding door. One or more support pieces are provided on each carriage. These support pieces come out below the slideway so that they are accessible to be

  attached to the top of the door when it is in place.

  The shape and width of the profiles 14 and 24 are such that it is possible to introduce the door into the structure by the non-recessed side (here between the upright 14 and the intermediate uprights 24). After that we fix the top of the door to the support parts of the carriages. Finally, as will be seen below, after installation of the door, the profiles of the monoblock structure are completed by profiled sections which

  reduce the width of the door frame.

  The threshold bar 22 at the bottom of the one-piece structure is preferably a planar profile of small thickness which is provided with a central guiding rib in the masked part, although it is not

  essential given the way in which the door is supported.

  In Figure 3, there is shown in more detail the attachment of the door to a movable carriage, in a preferred embodiment of the invention. The slideway 20 serving to guide the carriage is a hollow profile having bearing surfaces 34 for the wheels 32 of a mobile carriage 30. The carriage may have for example four wheels. Between the bearing surfaces, the slide has a longitudinal slot 36 allowing the passage of a support piece fixed to the

  trolley and intended to support the door.

  Here, the support piece is a bolt 38 whose head 40 is turned down and hangs below the slide to serve for the attachment of the door. The pin 42 of the bolt 38 passes through the slot 36 at the bottom of the slide, and its threaded end is screwed into a corresponding threaded bore 44 machined in the

body of the mobile carriage 30.

  The door 12 is suspended from the bolt head as shown in FIG. 3 and in the perspective view of FIG. 4: a notch 46 is formed at the top of the door; this notch is open laterally at least on one side of the door; this notch is also closed at its upper part by a metal plate 48 which itself has a notch 50 open laterally on one side (the same as the opening side of the notch 46 of the door if this

  last notch is only open on one side).

  The closure plate 48 is for example screwed into the upper part of the door on either side

of the notch 46 that it covers.

  The notch 46 serves for the passage of the bolt head; the notch 50 serves for the passage of the bolt rod but is too narrow to allow the head to pass so that when the bolt head is in the notch 46 the door can be suspended from the bolt, the bolt head being supported on the metal plate 48 on either side of the notch 50. The depth of the notch 50 is such that the bolt is automatically centered when it abuts against the bottom of this notch. FIG. 5 further represents, seen in a longitudinal direction, the same elements as in FIGS. 3 and 4, with the exception of the slideway, which is not shown there. It can be envisaged that there are two or three notches, or more, distributed at the top of the door 12, which is then suspended at a corresponding number of mobile carts provided with support pieces such as the

bolt 38.

  For the installation of the door, the door is placed in the frame as it will be in the closed position during use; the door is applied against the bolts hanging under the moving carriages, placing the carriages in such a way that the bolt heads penetrate the notches 46 and the rods of the carriages.

  bolts penetrate into the notches 50.

  The bolts are screwed by their heads (the notches 46 being wide enough to pass a tightening key) until the door is suspended in a balanced manner to the various mobile carriages. A lock nut may be provided on the bolt to tighten the closure plate between this locknut and the head

bolt.

  The rest of the installation consists of mounting auxiliary profiles on the one hand to ensure the complete closure of the opening and closing of the door, and on the other hand to improve the aesthetics of the door frame . These operations will now be described with reference in more detail to the profile shapes used for

  realization of the monobloc frame manufactured in factory.

  In Figure 6, there is shown vis-à-vis the constitution of the vertical upright 14 and intermediate amounts 24 forming the frame of the door 12 when mounted. The upright 14 is formed on the one hand by a main section 140 (in solid lines) which forms part of the one-piece structure mounted in the factory, and on the other hand by an auxiliary section 145 (in dotted lines) which is mounted

after setting up the door.

  Similarly, the intermediate amounts 24 may comprise main sections (in solid lines) 240, in two parts since they must be separated by a sliding slot of the door, and an auxiliary section 245 (in dashed lines). The main profiles are part of the factory assembled monobloc structure; the auxiliary section 245 is mounted after installation

in place of the door.

  The auxiliary profiles 145 and 245 serve to improve the aesthetics of the door frame, while adjusting the opening width of the frame so that it corresponds to the possibilities of movement of the sliding door taking into account the dimensions

of it.

  If the width of the door is Lp, the width L of the door frame must be less than Lp for the door to close the entire space of the door frame. But since the door must be inserted by insertion into the frame, it is necessary that the space Lm between the sections 140 and 240 of the monobloc structure is greater than Lp, at least on the side by which we will introduce the door. Auxiliary profiles reported after installation of the door make up the difference between Lm and L. In the example shown, the sections 140 and 240 are constituted asymmetrically. On one side of the door they have their final form, that is to say that they do not need additional profiles to acquire their final shape and to give to

  the door frame on this side its final appearance.

  They are separated by the distance L defining the definitive opening of the door. On the other side of the door the profile 140 and the profile 240 are more

away from each other.

  The auxiliary section 145, applied against the bottom of the profile 140 serves first shim E to reduce the displacement of the door in the direction of closure. Then, it is shaped so that all the profiles 140 and 145 constitute an aesthetic frame that has the same aspect of share and

else of the door.

  The auxiliary section 245 contributes to reducing from Lm to L the width of the door frame and also contributes to give an aesthetic appearance, identical to that found on the other side of the door. It is possible to do without this auxiliary section 245 if the catch of the width of the frame can be

  performed with the auxiliary section 145 alone.

  This last solution then presents

  the advantage of simplifying the assembly.

  In much the same way, as shown in FIG. 7, it is anticipated that the lintel of the door comprises not only a main profile 180 and the slide 20 which are two elements (solid lines) forming part of the rigid one-piece frame. mounted at the factory, but also an auxiliary profile intended to improve the aesthetics of the upper part of the door frame. This complementary profile 185 (dashed lines) masks the bolt rods used to support the door; it also masks the attachment means constituted by the notches and metal plates at the top of the door. It is mounted after installation of the door, along with the profiles 145 and 245. Again, the profile 185 gives the door on the side where it is introduced the same appearance as the other side. Profil 185 also contributes to the good

guiding the door.

  The mounting of complementary profiles is practically by simple interlocking; it can be provided for example that one of the profiles (145 preferably) is slightly shorter than the height it should have a separate wedge of the same profile to then complete this height. The profiles 145 and 245 and the profile 185 which rests at its ends on the profiles 145 and 245 are placed in the manner of a keystone, and all that remains is to slide the shim under the profile. too short, this wedge naturally jamming all. complementary fixing means may be provided in addition if it is

desire (screws, etc.).
