[0001] Description l ' irn / pn n • SLIDING OPENING COMPRISING A SLEEVE WITH A HANDLE AND
[0002] 'FRAME COMPRISING SUCH AN OPENING
[0003] Technical field
[0004] The invention relates to an opening comprising a handle, intended to slide in a frame. It also relates to a door frame comprising such an opening.
[0005] Prior art
[0006] Frames with glazed sliding sashes have been known for a long time. The sashes are formed by profiles, for example made of aluminum, which surround a pane of glass. The sashes are equipped on each side with a handle for operating the sashes. Generally, the handle is attached to the beam facing the wall.
[0007] Recently, frames have been proposed that appear even more integrated. With this in mind, a frame has been proposed whose vertical upright has a groove into which the opening can be inserted when closing. The upright appears to be completely integrated into the wall. With such a construction, the handle must be offset towards the center of the glazing, in order to allow the opening to be inserted into the groove. Thus, the handle has the shape of an angle iron, the first wing of which is fixed to the side member while the second wing is used for gripping by the user. To prevent the first wing from protruding from the first side member, machining is provided on the side member to insert the first wing so that the visible face of the first wing is flush with the face of the side member parallel to the plane of the opening.
[0008] It is also generally planned to integrate a lock into the side member which cooperates with a strike plate integrated into the frame.
[0009] Machining the handles and locks is a fairly complex operation that requires the use of a machine such as a CNC machining center. However, most carpenters who manufacture this type of joinery are not equipped with such a machining center. Moreover, even with such equipment, the machining operations are relatively long and therefore expensive.
[0010] Statement of the invention
[0011] It is therefore an objective of the invention to remedy the drawbacks of the prior art. It is in particular an objective to provide an opening whose construction does not require complex tools and is quick to implement.
[0012] With these objectives in view, the invention relates to a sliding opening intended to fit into a groove of a frame by sliding in a direction of operation in a plane of the frame, the opening being delimited by a frame composed of side members, a first of the side members being provided to fit into the groove and comprising at least one fixed handle, the side member being formed by two profiles abutting a sleeve respectively on either side of said sleeve, the sleeve supporting the handle.
[0013] According to one arrangement, the handle is flush with the profiles in a plane parallel to the plane of the opening so as not to hinder the insertion of the opening into the groove of the frame.
[0014] Thanks to the invention, it is possible to provide that the sleeve integrates all the functions necessary for the constitution of the spar and to assemble the spar very easily by assembling it with the profiles. Thus, during the manufacture of the opening, the carpenter simply has a cutting operation, then the two abutments to be made to obtain the spar. This operation only requires tools that he already has, such as a saw for sawing the profiles and a drill. The sleeve is obtained for example by molding, it can therefore integrate many functionalities without significant cost per unit. The handle can be fixed to the spar without the upright of the frame needing to be ground. The width of the spar is not increased by the presence of the handles. This is easily achieved by providing that the sleeve is of a thickness less than the width of the profiles.
[0015] According to a constructive arrangement, each profile has at least one longitudinal cavity, the sleeve comprising for each profile a tenon adjusted and fitted into each cavity. The profiles are generally provided with cavities, also called chambers, which make it possible to lighten the profile while obtaining good resistance and better thermal behavior. By providing tenons which are inserted into the chambers of the profiles, an excellent mechanical coupling in bending is achieved between the profile and the sleeve.
[0016] According to an improvement, the spar comprises at least one locking system between the sleeve and one of the profiles, the locking system comprising a first hole in the spar opening into the cavity, a second hole in the tenon and a key housed in the first and second holes. The first hole is made to measure by the carpenter, which only requires a drill. The second hole is generally already provided in the tenon. In practice, the role of the key can be held by a screw or by a force-fitted pin.
[0017] According to an improvement, the sleeve comprises a housing and a lock fixed in the housing, the lock being intended to cooperate with a strike plate housed in the groove of the frame. The production of the housing does not require machining since it is directly integrated into the sleeve.
[0018] According to an improvement, the handle comprises a slider and transmission means for controlling the lock by moving the slider between a locking position and a release position. It is thus possible to accommodate the locking functions of the opening in a location where it will be easy to plan the volumes and surfaces to integrate them without complication.
[0019] According to a constructive arrangement, the sleeve comprises at least one spacer extending between the end of the profile and the handle and flush in a plane parallel to the plane of the opening. The spacer serves both as a stop for positioning the sleeve in the profile and as a visual finish for the junction between the handle and the profile.
[0020] According to one embodiment, the opening comprises glazing surrounded and held by the frame.
[0021] The invention also relates to a sleeve for a sliding opening intended to be fitted into a groove of a frame by sliding in a direction of operation in a plane of the frame, the opening comprising a first longitudinal member provided to be fitted into the groove, the sleeve being provided to form the longitudinal member by receiving two profiles by abutment and to receive at least one fixed handle between the two profiles, the handle being flush with the profiles in a plane parallel to the plane of the opening so as not to hinder the insertion of the opening into the groove of the frame.
[0022] According to one embodiment, the sleeve is made of thermoplastic synthetic material. This material, which is commonly used for the manufacture of joinery parts, has the advantage of being very resistant and of controlled manufacturing. The synthetic material can be polyamide or PMMA, preferably filled with powders or fibers, for example glass.
[0023] The invention also relates to a closure for a building comprising a frame and an opening intended to fit into a groove of the frame by sliding in a direction of operation in a plane of the frame, characterized in that the opening is as defined above. Closure means the assembly which makes it possible to reconstitute a building wall, such as windows or doors.

[0033] Detailed description
[0034] A closure for a building is shown in Figures 1 to 8. The closure is a French window comprising two openings 1 and a frame 2. The frame 2 has the shape of a rectangular frame which is intended to be fixed on an opening of a vertical wall of a building, not shown. The two openings 1 are mounted sliding horizontally in an operating direction F1 inside the frame 2 while being offset from each other. Along vertical uprights 20, the frame 2 has a groove 21 in which the openings 1 are intended to fit by sliding in the operating direction F1 in a plane of the frame 2.
[0035] Each opening 1 is made in a similar manner, so the description will only relate to one of the openings 1. The opening 1 is delimited by a frame composed of side members 11 and comprises a glazing 10 surrounded and held by the frame. The assembly of the side members 11 together to form the frame is conventional and is not detailed here. A first 11a of the side members 11 is designed to fit into the groove 21 and comprises two fixed handles 12a, 12b, respectively on either side of the glazing 10.
[0036] As can be seen in particular in Figure 6, the spar 11a is formed by two profiles 111, only the ends of which are shown, abutting a sleeve 3 at the level of the handles 12a, 12b, respectively on either side of said sleeve 3. Each profile 111 comprises two metal parts 1110 made of extruded aluminum, connected together by two junctions 1111 made of synthetic material. Each metal part 1110 comprises a longitudinal cavity 1112 and a wing 1113 to bear on the periphery of the glazing 10 by means of a seal, not shown. The sleeve 3 comprises for each profile 111 five tenons 30a, 30b, two of which 30a are adjusted and fitted into the respective cavities 1112 of the metal parts 1110. The other three tenons 30b, smaller in size than the first tenons 30a, are adjusted and fitted at the level of the junctions 1111 made of synthetic material.
[0037] The sleeve 3 is made in one piece by molding a thermoplastic synthetic material and comprises a central body 31 formed by two rules 310, each rule 310 being in the extension of two tenons 30a, 30b to form a continuity from one profile 111 to the other. The rules 310 are connected to each other by a web 311. A spacer 32 is provided at each end of the central body 31, the tenons 30a, 30b projecting from the spacer 32. The spacer 32 extends between the end of the profile 111 and the handle 12a, 12b and is flush in a plane parallel to the plane of the opening 1.
[0038] The spar 11a comprises a locking system 4 between the sleeve 3 and each profile 111. The locking system 4 comprises first holes 41 in the spar 11a opening into the cavity 1112, a second hole 42 in each first tenon 30a and a screw forming a key 40 housed in the first hole and screwed into the second hole 42. Each handle 12a, 12b has the shape of an angle iron of which a first wing 121 is fixed on the sleeve 3 while the second wing 122 is used for gripping by the user and projects from the spar 11a. To prevent the first wing 121 from projecting from the first side member 11a, provision is made for the rule 310 on which the handle 12a, 12b is fixed to be set back, so that the visible face F of the first wing 121 is flush with the face G of the side member 11a parallel to the plane of the opening 1. In this way the handles 12a, 12b do not hinder the insertion of the opening 1 into the groove 21 of the frame 2.Furthermore, the rule 310 incorporates a groove 3101 along the direction of the spar 11a and the handle 12a, 12b comprises a rib 123 which is intended to be inserted into the groove 3101. Each handle 12a, 12b is provided with two studs 124 which are inserted into holes 33 provided for this purpose in the sleeve 3.
[0039] It is also planned to integrate into the side member 1 a lock 6 which cooperates with a strike plate integrated into the frame 2, not shown. The lock 6 is housed in a housing 312 formed between the two rules 310 on the edge of the opening 1. The lock 6 further comprises four dowel holes 60 to receive the dowels 124 which thus pass through the lock 6. The lock 6 comprises pressure screws 61 opening into the dowel holes 60 in order to lock by tightening the dowels 124 in the holes, and thus fix the handles 12a, 12b. The pressure screws 61 are accessible from the edge of the opening 1.
[0040] One of the handles 12b comprises a slider 125 and transmission means 7 for controlling the lock 6 by moving the slider 125 between a locking position, as shown in FIG. 7, and a release position by translation in the direction of movement of the opening 1. The transmission means 7 comprise in particular a finger 70 which projects perpendicularly to the first wing 121 and which is inserted into the lock 6 to maneuver the bolt 62 in a translational movement in an up-down movement or vice versa. The transmission means 7 comprise for example an oblique cam, not visible, cooperating with a stud, not visible, to transform the translation of the slider 125 into translation of the finger 70.
[0041] To manufacture the opening 1, the two profiles 111 are cut to the desired length, and the first holes 4L are drilled. The profiles 111 are fitted onto the tenons 30a, 30b of the sleeve 3 and then the screws 40 are fixed through the first and second holes 41, 42. The frame of the opening 1 and the glazing 10 are shown in a conventional manner, not detailed here. The lock 6 is mounted, then the handles 12a, 12b by inserting the studs 124 into the sleeve 3 and the stud holes 60 of the lock 6. The pressure screws 61 are tightened and the opening 1 is thus mounted. The opening 1 is placed in a conventional frame 2, in a manner not detailed here. Optionally, the longitudinal member 11a is glued at least partially to the glazing to stiffen the frame.
[0042] The invention is not limited to the embodiment described solely as an example. The closure could be a window or a solid door. The sliding of the opening could be vertical. The material of the sleeve could be metallic, for example aluminum alloy.
