Description

Arrangement of a tilt limiter arm of sash windows.

The present invention relates to windows of guillotine, and in particular to a limiter arm assembly of guillotine window inclination that limits the inclination of a sliding and tilting guillotine window.

Sash windows comprise normally a couple of window sheets placed and supported inside  of vertical channels in lateral jambs of a window frame. The window sheets are arranged to slide vertically inside the window frame to allow to open the window. Be provides a counterweight mechanism to counterbalance the weight of the window sheets and allow more vertical sliding Simple window panes. The sash windows more modern are also arranged so that the sheets of window can also be tilted outside the window frame in around a horizontal axis, usually along or at the edge bottom of the window sheets. Such inclination of the leaves of window is provided to allow maintenance access and, in particular, to allow easier cleaning of the windows window sheets being arranged, usually for swing in.

In such arrangements, normally provide tilt-limiting arms (in some sometimes called tilt supports) to support the window leaf weight when tilted from the frame of the window and to prevent the window leaves from tilting completely out of the window frame. One end of the arm tilt limiter is placed and hooked in the channel window jamb and the other end of the limiter arm of tilt is fixed to the window leaf at half the length on the side of the blade and in a separate position from the pivot bar and of the axis on which the window is tilted. With the purpose of allow the inclination of the window, at least one end of the tilt limiter arm is hooked so sliding with the window jamb and / or respective window leaf, so that while it is attached it can slide along the leaf length / window jamb.

Although the limiter arm provisions of Conventional inclinations work properly and prevent a excessive inclination of the window sheets, such arrangements can be improved, in particular, in terms of the ease of mounting and fixing to the window and the limiter, as well as in terms of provide improved operation of window sheets. Specifically, fixing the limiter arms of Conventional inclination to the window sheets and / or to the jamb of Window can be complicated and difficult, and such arrangements they can be relatively difficult to install and / or they can create difficulties during the installation of window panes, in particular during the replacement of the window sheets inside of the window frame. In addition, although it is generally desirable limit the inclination of the window sheets, in certain circumstances, for example during the replacement or in a emergency, it may be desirable to allow additional tilt and / or a disassembly of the sheets.

Various arrangements of supports widely known inclination, particularly for windows Conventional hinge, are described for example in the documents: GB 355.396, DE 3302354, EP 0.499.708, GB 428.105, DE 1759963, EP 0.383,003, GB 2,309,484, GB 2,259,947, GB 2,145,151, US 3,728,820, WO 00/49258 and EP 0.833.028. However, the hinge windows they are very different from sash windows and, due to the operating difference, sash windows and Guillotine window holders are subjected to fully functional and construction requirements. In In particular, sash windows are required to slide mainly within the frame, being the inclination and the supports only a complementary feature that should not hinder the main sliding of the sash window. The installation and assembly of the sash windows are also very different from those of a hinge window.

Therefore, it is desirable to provide a improved arrangement of a tilt limiter arm of sash windows that overcome the problems described previously and / or that offer improvements in a general way.

According to the present invention, a Improved set of window tilt limiter arm guillotine described according to claim 1 attached. I also know provides a sash window assembly described according to the claim 14 attached and including a limiter arm of Tilt of guillotine windows of this type.

Such an arrangement allows unhook the limiter arm easily and simply tilt of the window leaf to allow an opening of wider inclination of the window sheets, if necessary, and also an easier disassembly / installation of the sheets window.

The window leaf mounting arrangement preferably comprises a pin that protrudes from the second arm end, the pin presenting a distal end that It comprises an enlarged head. During use, the pin and the extended head are placed and held in an elongated groove which presents an enlarged access input part along the length of the groove sized to allow inserting into and remove the extended head from the slot. The elongated groove has preferably a stepped profile with walls defining a containment surface on which the extended head engages and is subject

This provides a detachable clamp, simple and easy from the tilt arm to the blade window avoiding the use of screws or other elements of clamping that require the use of tools.

The elongated groove can be defined in the window sheet Alternatively, the window sheet set tilting can also comprise a sheet mounting bracket window that can be attached to the window leaf frame and inside the which is defined the elongated groove. Blade mounting bracket Window is preferably located within a defined channel in a window pane frame. The blade mounting bracket window can also further comprise at least one tab of protruding placement of window leaf mounting bracket and that can get caught in a recess or opening defined in the frame of window leaf. The distal end of the at least one eyelash of placement preferably has an angled profile.

The frame mounting arrangement comprises a frame mounting block adapted to be placed so sliding within a channel defined in the window frame and to be pivotally fixed to the first end of the arm.

The present will be described below invention, by way of example only, with reference to following figures, in which:

fig. 5 is a more detailed view of a window assembly mounting bracket arm assembly tilt limiter;

Referring to fig. 1, a window of guillotine 10 comprises a window frame 1 that includes elements of vertical side frame jamb 6, 8, and a pair of sheets of Window 2, 4 placed vertically and slider inside the window frame 1. Window sheets 2, 4 are arranged generally vertically in an overlapping arrangement, window sheets 2, 4 being arranged adjacently and very close to each other and, in operation, sliding one by behind the other. The vertical window jamb elements 6, 8 each define two jamb channels of window 12, 14 that are extend vertically, as shown more clearly in the fig. 3, for the respective window sheets 2, 4. The channels of window jamb 12, 14 of the double channel section in each jamb of window 6, 8 are arranged juxtaposed and adjacent along the length of the side window jambs 6, 8 adjacent to the side of the respective window sheets 2, 4. These window jamb channels 12, 14 have an open part  facing the respective sides of the window sheets 2, 4. The window frame 1 and the side window jambs 6, 8 They are normally manufactured from UPVC sections extrudates that are joined together, although they can also be used other materials such as metal, aluminum or wood.

Each window leaf 2, 4 is hooked and supported in the window frame by a pair of bars pivot (not shown) placed at the bottom of the blades window 2, 4. Pivot rods extend and protrude laterally from the sides of the window sheets 2, 4. Pairs of tilt latches (not shown) for each window sheet 2, 4 are placed on top of the window sheets 2, 4 and project laterally similarly from the sides of the window leaves 2, 4. The distal ends of the latches tilt and pivot bars are hooked to the respective window jamb channels 12, 14, thus placing slidingly the window sheets 2, 4 within the frame of window 1. Counterweight provisions (not shown) for counterbalance the weight of window sheets 2, 4 and to make the vertical sliding of the window sheets 2, 4 be more easy, they are mounted and placed inside the jamba channels 12, 14 and fixed to window sheets 2, 4 and normally at pivot bars Specifically, pivot bars can engage in window mounted sliders so mounted sliding in the window jamb channels 12, 14 and connected to counterweight provisions and specifically to one end of helical springs Such counterweight provisions they normally comprise one or more helical springs and are widely known in the art being described, for example, in published British patent applications GB2369644 and GB2380758, or in U.S. Patent Nos. US6412144, US6393661, US5365630, which also describe in a manner generic such sash windows.

Tilt latches can retract laterally with respect to the window sheets 2, 4 so that the distal ends of the tilt latches can separate from the window frame jamb channels 12, 14. Such separation, in operation, allows the upper part of the Window sheets 2, 4 disengage from window frame 1 allowing window sheets 2, 4 to swing and pivot around the pivot bars and a horizontal axis through from the bottom edge of the window sheets 2, 4, as illustrated in fig. one.

A pair of arm limiter sets tilt 16 for each window leaf 2, 4 is connected and extends between window frame jambs 6, 8 and frames sides 3, 5 of the window panes 2, 4 to limit and prevent excessive inclination of window sheets 2, 4 and to maintain to the window sheets 2, 4 in a tilted position. With the Window sheets 2, 4 in such tilted positions, normally tilted inside a building, the outer surface Window sheets 2, 4 and window 10 can be cleaned easily and / or other maintenance operation of the sheets window 2, 4 and window 10 can be done in a more simple. In particular, the limiter arm assemblies of tilt 16 make the window sheets 2, 4 not need keep manually in its tilted position., When Window sheets 2, 4 are in the normal vertical orientation, the tilt limiter arm assemblies 16 are arranged in parallel to the sides and along the side frames 3, 5 of the window leaves 2, 4 and slide vertically with the leaves of window 2, 4. Specifically, and in this embodiment, one end jamb window tilt limiter arm assembly 16 is slidably placed and engaged inside the channel of window jamb 12, 14 by means of a mounting arrangement of frame 20 while the window leaf end of the set tilt limiter arm 16 is fixed so pivoting to the side frame of window leaf 3, 5 by means of a window leaf mounting arrangement 21, as will describe later in greater detail. During tilt and pivot movement of the window panes 2, 4, the arms tilt limiters 16 pivot around the connections and of mounting arrangements 20, 21 for window jambs 6.8 and the window sheets 2, 4.

As such, the sash window 10 described It is previously conventional.

Referring now in greater detail to tilt limiter arm assembly 16 according to the present invention, this is shown in greater detail in figs. 2 to 5. Without However, it will be appreciated that certain elements of the window guillotine 10 have been omitted in figs. 3 and 4 for clarity and that the illustrations are not necessarily to scale.

As shown in fig. 2, the set of tilt limiter arm 16 comprises an arm element elongated 22. The window jamb frame mounting arrangement 20 comprises a jamb frame assembly block 50 that is pivotally fixed to one end of the arm 22 by, by example, a rivet 52. The window jamb channels 12, 14 19 dividers are subdivided by walls or flanges, such and as shown in fig. 3, to define a camera of counterweight 17, within which the set of counterweight (not shown), and a limiter arm mounting channel of inclination 15. The frame mounting block 50 has a size and is sized to be slidably placed inside the  tilt limiter arm mount camera 15 way that while it can slide vertically inside the chamber 15 and of channel 12, 14, it will be firmly placed in them. He mounting block 50 can be installed inside this chamber 15 a through a part defined by an enlarged shaft opening defined at half the length of the window jamb channel 12, 14. Alternatively, mounting block 50 can be inserted inside the channel chamber 15 from one end before assembly of the window frame 1.

The other end of the limiter arm assembly of tilt 16, and of the sheet mounting arrangement of window 21, is arranged and adapted to fix releasably the tilt limiter arm 22 to the window leaf 2, 4 and to allow the tilt limiter arm 22 to pivot with with respect to the window leaf 2, 4. In addition, and preferably, the window leaf mounting arrangement 21 also provides and allows a limited degree of relatively sliding movement of the tilt limiter arm 22 with respect to the window leaf 2, 4. Such limited slip allows more inclination single window leaf 2, 4.

Specifically, and as illustrated in this embodiment, window leaf mounting arrangement 21 comprises a mounting pin 30 protruding from one end of the arm 22 and that is hooked and placed detachably on a window limiter arm mounting bracket tilt 18 that is firmly attached and attached to the frame side window leaf 3, 5, as shown in figs. 3 and 4 and as described later in greater detail. He window arm mounting bracket for limiter arm Tilt 18 includes an elongated groove 32 defined therein. The elongated groove 32 has a stepped cross section and it comprises a first section 34 that has a first width W_ {1} and a second section 36 superimposed on the first section and which has a second width W_ {2} greater than the first width W_ {1} with a flat containment surface 40 defined between the two sections The mounting pin 30 comprises a part of stem 31 with an enlarged head 33 at the distal end of the part of rod 31 and pin 30.

An enlarged keyhole opening 38 is defined through the window leaf mounting bracket tilt limiter arm 18 half the length of the elongated groove 32 extending the width of the first section 34 of the elongated groove 32 in the eye opening region of lock 38. The width W_ {1} of the first section 34 is corresponds to the width / diameter of the rod 31 of the pin 30, while the width W_ {2} of the second section 36 is corresponds to the width / diameter of the enlarged head 33. The keyhole opening 38 generally corresponds to the shape and size of the enlarged head 33 so that the head enlarged 33 and pin 30 can be inserted through the keyhole opening 38 and can be placed inside the elongated slot 32. Once inserted in slot 32, the head enlarged pin 30 is placed and held securely within the second section of the groove 32 by the surface of containment 40 that makes contact with the bottom of the head enlarged 33 once pin 30 has slid along of slot 32. To remove pin 30 from slot and to separate the arm 22 from the window leaf mounting bracket tilt limiter arm 18, pin 30 slides with the slot 32 until extended head 33 is aligned with the keyhole opening 38, point at which the pin 30 can exit slot 32 through the eye opening of lock 38. Accordingly, pin 30 can be engaged and be placed in a releasable and detachable manner inside the groove elongated 32.

Sizing the keyhole opening 38 so that it corresponds closely to the extended head 33 and a meticulous alignment of the head with the opening 38 for extraction, the risk of the pin 30 accidentally and inadvertently disengaged from the slot 32. In addition, providing the keyhole opening 38 a half the length of the groove 32 and away from the ends of the groove and / or where, in operation, the pin 30 may be generally placed, the head is further prevented enlarged 33 accidentally aligns with opening 38 and that the pin 30 disengages from the groove. In one embodiment and alternative variation, a shutter element (not shown) can insert and fit into the keyhole opening 38. The shutter element can completely or completely block the opening of keyhole 38 thereby preventing the head expanded 33 out of opening 38. Therefore, the element shutter more securely prevents pin 30 from getting out of inadvertent way of the groove through the eye opening of lock 38. With such a shutter element, the opening keyhole 38 is normally placed at one end of the slot 32, beyond the normal movement of pin 30 within the slot 32 since the sealing element can prevent the movement of pin 30 beyond the sealing element. Without However, if the sealing element only partially fills the opening 38 so that slot 32 continues through the shutter element, then there is no restriction about the positioning of the opening 38 and the sealing element.

The tilt limiter arm window leaf mounting bracket 18 is fixed and firmly attached to the window leaf 2, 4 within a defined channel section 24 along the window leaf side frames 3, 5. A pair of positioning tabs 42 protrude from the mounting bracket 18 and are engaged and placed within corresponding placement openings 44, defined in a rear wall 25 of the channel section 24 of the window leaf side frames 3, 5 to place the mounting bracket 18 longitudinally along the channel 24 and the window leaf 2, 4. Front walls 26 defining the section of the channel 24 keep the mounting bracket 18 and the flanges inside the channel 24. The mounting bracket 18 can be inserted and held within the channel 24 either through an enlarged access opening (not shown) or, alternatively, simply by sliding into the open end of the channel 24. Ta The enlarged access opening may be an existing feature of the window leaf channel 24 provided at half the length of the channel 24. Alternatively, an access opening, adjusted to the size of the mounting bracket 18, can subsequently be machined in the sheet of window 2, 4 and in the channel 24, eliminating respective located parts of the front part 26 to allow the adaptation of the mounting element 18 and the limiting element 16 to the existing window sheets. The mounting bracket 18 then slides longitudinally along the channel 24 until the positioning tabs 42 are placed and hooked into the positioning openings 44 of the rear channel wall 25. In this embodiment, the leaf frame of window 3, 5 and in particular the front walls 26 and / or the rear channel wall 25 defining the channel 24, have a degree of elasticity, and the mounting bracket 18 is sized to substantially fill the channel section 24. Accordingly, the front walls 26 and / or the rear channel wall 25 are curved and deformed with the distal ends of the positioning tabs 42 that make contact with the rear wall 25 of the channel 24 when the mounting bracket 18 is attached in and slides along the channel 24. Once the placement tabs 44 are engaged and secured in the placement openings / recesses 44, the elasticity of the front walls 26 and / or the rear wall of channel 25, will push the mounting bracket 18 against the rear wall 25 and the positioning tabs 42 into the placement holes 44 so that the placement tabs 42 are held in the placement openings 44. it will be appreciated that although the use of a pair of positioning tabs 42 is preferred, as shown in this embodiment, in alternative embodiments a single flange 42 or more may be used
tabs 42.

To allow separation of the support from assembly 18, if necessary, the distal end of the eyelashes of placement 42 preferably has an end surface angled 46. The angled shape of the distal end surface 46 and of the positioning tab 42 is arranged so that the placement tab 42 engages with opening 44 and resists the movement of the mounting bracket 18 under normal load, which It is usually applied during use in one direction (down, as shown in fig. 4). Under such normal load, a protruding edge surface 45 of positioning flange 42 is hooks and makes contact with the opening walls and resists the movement. However, if the mounting bracket 18 moves in a separation direction (upwards, as shown in fig. 4), the placement tab 42 leaves itself from the placement opening 44 with the edge of the opening 44 then sliding on the angled surface 46 and making that the front walls 26 and / or the rear wall of channel 25 are They curl and warp out against their elasticity.

In additional alternative embodiments, the window leaf side frames 3, 5 can be substantially rigid. In such cases, placement tabs 42 are configured to elastically deform to allow holding the mounting bracket 18 inside channel 24. Alternatively, the placement tabs 42 may be configured to retract elastically inside the mounting bracket 18. It will also be appreciated  that although the use of such placement tabs 42 and fastening of mounting bracket 18 within a channel 24 in the sheet frame Window 3, 5 provides simple and convenient means to fix and fasten the mounting bracket 18 to the side sheet frame window 3, 5, the mounting bracket 18 could be fixed from others ways. In addition, in yet another additional embodiment, the support Mounting 18 can be integral to the window leaves 2, 4 and a the window leaf side frames 3, 5. In fact, in still another alternative embodiment, the elongated groove 32 and the opening of expanded keyhole 38 could be directly machined or be formed in another way in the window leaf frame 3, 5.

The releasable and detachable arm fixation tilt limiter 22 to window leaves 2, 4 provided by the tilt limiter arm assembly 16 described, it is much simpler and faster to hold the previous conventional provisions. In particular, I don't know requires no additional fasteners (screws) or tools for holding and fixing the tilt limiter arm 22 to window blades 2, 4. The tilt limiter arm 22 can be fixed in a simple and simple way and also separated  of the window leaf simply by sliding and aligning the respective mounting pins 30 with the eye opening of lock 38 and flexing the tilt limiting arms 22 slightly laterally outward to allow the pin 30 exit the elongated groove, thus separating the arm 22 of the window leaf 2, 4. This arrangement may compare with the previous conventional provisions in the that the tilt limiting arms are attached or permanently fixed using screws or other elements of similar fasteners that are uncomfortable to remove and hold and that require the use of tools such as a screwdriver.

The simple releasable and detachable fixing of the tilt limiter arm 22 to window leaves 2, 4 it also allows the tilt arm 22 to separate from a easiest and simplest way of window sheets 2, 4 to allow window sheets 2, 4 to be additionally tilted and to provide a greater opening for, for example, provide a simpler emergency exit through the window and also to provide maintenance access improved and more comfortable, as well as to allow disassembly and / or easier installation of window panes 2, 4. Specifically, if the tilt limiting arms 16 are separated from the window sheets 2, 4, this allows the sheets of window 2, 4 are fully tilted (usually so horizontal) so that the pivot bars align with the openings and can be disengaged from the sheet sliders window that normally hold them in the channels of window jamb 12, 14 then allowing the leaves of window 2, 4 separate from window 1.
