OPENING HANDLE COMPRISING A HANDLE AND FRAME COMPRISING A

TEL OPENING

Technical area

The invention relates to an opening comprising a handle, intended to be slidable in a frame. It also relates to a frame comprising such an opening.

State of the art

Frames with sliding glass openings have been known for a long time. The opening is formed by profiles, for example aluminum, which surround a glazing. The opening is fitted on each side with a handle allowing the opening to be operated. Typically, the handle is attached to the spar that faces the wall.

Recently, frames have been proposed whose appearance appears even more integrated. With this in mind, we have proposed a frame whose vertical upright has a groove into which the opening can be inserted when closing. The stud 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 insertion of the sash into the groove. Thus the handle has the shape of an angle, a first wing of which is fixed on the spar while the second wing is used for gripping by the user. To prevent the first wing from projecting onto the first spar, machining is provided on the spar to insert the first wing in such a way that the visible face of the first wing is flush with the face of the spar parallel to the plane of the spar. 'opening.

We also generally plan to integrate a lock into the spar which cooperates with a striker integrated into the frame.

Carrying out the machining to integrate the handles and the lock are quite complex operations which require the use of a machine such as a numerically controlled machining center. However, the carpenters who manufacture this type of joinery are for the most part not equipped with such a machining center. Furthermore, even with such equipment, the machining operations are relatively long and therefore expensive.

Object of the invention

It is therefore an objective of the invention to remedy the disadvantages 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 and minimizes the risk of errors.

General description of the invention

With these objectives in mind, the subject of the invention is a sliding opening intended to fit into a groove of a frame by sliding in a direction of maneuver in a plane of the frame, the opening being delimited by a frame composed of spars, a first of the spars being designed to fit into the groove and comprising at least one handle, characterized in that the spar is formed by two profiles abutting a sleeve respectively on either side of said sleeve, the sleeve supporting the handle.

Thanks to the invention, it can be provided that the sleeve integrates all the functions necessary for the constitution of the spar and the spar can be mounted very easily by assembling it with the profiles. So when manufacturing the opening, the carpenter simply has a straight cutting operation, then the two joints to be made to obtain the spar. This operation only requires tools that he already has, such as a saw to saw the profiles and a drill or punching machine to make holes. The sleeve is obtained for example by molding, it can therefore integrate numerous functionalities without significant cost per unit while avoiding complex machining. We can ensure that the assembly has adequate mechanical strength and provides beautiful aesthetics and water and airtightness suitable for the window.

According to a constructive arrangement, each profile comprises 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 allow the profiles to be assembled using brackets and to lighten the profile. By providing tenons which insert into the chambers of the profiles, excellent mechanical coupling in flexion is achieved between the profile and the sleeve.

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 custom made by the carpenter, which only requires a drill or punching tool. The second hole is generally already provided in the tenon. In practice, the role of the key can be played by a screw or by a force-fitted pin.

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. Thus the handle can be fixed to the spar without the frame upright needing to be ground. The width of the spar is not increased by the presence of the handles. This is easily obtained by providing that the sleeve is of a thickness less than the width of the profiles.

According to an improvement, the sleeve comprises a housing and a lock fixed in the housing, the lock being intended to cooperate with a striker housed in the groove of the frame. The creation of the housing does not require machining since it is directly integrated into the sleeve.

According to an improvement, the handle comprises a slide and transmission means for controlling the lock by moving the slide between a locking position and a release position. We can thus house the locking functions of the opening in a place where it will be easy to plan the volumes and surfaces to integrate them without complications.

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 to position the sleeve in the profile and as a visual finish for the junction between the handle and the profile.

According to one embodiment, the opening includes glazing surrounded and held by the frame.

The invention also relates to a sleeve for 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 comprising a first spar intended to fit into place in the groove, characterized in that the sleeve is designed to form the spar by receiving two profiles by abutting and to receive at least one fixed handle between the two profiles.

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. It also benefits from low thermal conductivity, which makes it a material of choice in this application. The synthetic material must be polyamide or PMMA, preferably filled with powders or fibers, for example glass.

According to another embodiment, the sleeve is made of molded metal material.

Such a material is for example an aluminum alloy such as zamac. Such a material has good resistance and is easily implemented by molding with good precision.

The invention also relates to a closure for a building comprising at least one frame and an opening intended to fit into a groove in the frame by sliding in a direction of maneuver in a plane of the frame, characterized in that the opening is as defined previously. By closure we mean the assembly which makes it possible to reconstruct a building wall, such as windows or doors.

detailed description

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 direction of maneuver F1 in a plane of the frame 2.

Each opening 1 is constituted 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 longitudinal members 11 and includes glazing 10 surrounded and held by the frame. The assembly of the spars 11 together to form the frame is classic and is not detailed here. A first 11a of the longitudinal members 11 is designed to fit into the groove 21 and has two fixed handles 12a, 12b, respectively on either side of the glazing 10.

As 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 in extruded aluminum, connected together by two junctions 1111 in synthetic material. Each metal part 1110 comprises a longitudinal cavity 1112 and a wing 1113 to bear on the periphery of the glazing 10 via 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 three other tenons 30b, of smaller size than the first tenons 30a, are adjusted and fitted at the junctions 1111 in synthetic material.

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 of a profile 111 to the other. The rules 310 are connected together 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 are flush in a plane parallel to the plane of the opening 1.

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 spar 11a, it is provided that the rule 310 on which the handle 12a, 12b is fixed is set back, such that the visible face F of the first wing 121 is flush with the face G of the spar 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. In addition, rule 310 integrates a groove 3101 in the direction of the spar 11a and the handle 12a, 12b includes 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.

It is also planned to integrate into the spar 11a a lock 6 to obtain the locking of the opening 1. The lock 6 is housed in a housing 312 provided between the two rules 310 on the edge of the opening 1. The lock 6 further comprises four stud holes 60 to receive the studs 124 which thus pass through the lock 6. The lock 6 comprises pressure screws 61 opening into the stud holes 60 in order to lock the studs 124 in the holes by tightening, and thus fix the handles 12a, 12b. The pressure screws 61 are accessible from the edge of the opening 1.

One of the handles 12b comprises a slide 125 and transmission means 7 for controlling the lock 6 by moving the slide 125 between a locking position, as shown in Figures 7 and 10, and a release position by translation in the direction of movement of the opening 1, as shown in Figure 11. The transmission means 7 include in particular a finger 70 which projects perpendicularly to the first wing 121 and which is inserted into the lock 6 to operate the bolt 62 in a translation movement in an up and down movement or vice versa. The transmission means 7 comprise for example a cam with an oblique cam groove 720 71 secured to the slide 125 cooperating with a pin 72 secured to the finger 70 to transform the translation of the slide 125 into translation of the finger 70, as can be seen in detail in Figure 12. The bolt 62 drives a rod 63 sliding along the edge of the opening 1.

The rod 63 has several lights, not shown, into which bulb pins 64 are inserted when the opening slides against the frame. Locking is obtained by narrowing the slots behind which the bulbs of the pins engage during vertical sliding of the rod 63.

To manufacture the opening 1, we cut the two profiles 111 to the desired length, and we drill the first holes 41. We fit the profiles 111 onto the tenons 30a, 30b of the sleeve 3 then we fix the screws 40 through the first and the second holes 41, 42. The frame of the opening 1 and the glazing 10 are shown in a conventional manner, not detailed here. We mount the lock 6, then the handles 12a, 12b by inserting the studs 124 into the sleeve 3 and the stud holes 60 of the lock 6. We tighten the pressure screws 61 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 beam 11a can be glued at least partially to the glazing to stiffen the frame.

The invention is not limited to the embodiment which has been described solely by way of example. The closure could be a window or a solid door. The sliding of the sash could be vertical. The upright profiles could be without joints in synthetic material but with sails in one piece with the rest of the profile. The sleeve could be made of metallic material such as an aluminum alloy and made by molding. The closure could have a single opening that slides along a solid wall or a fixed window, or even more than two openings.
