Definitions
- the invention concerns a frictional locking device for stopping a door or window wing hinged to a stationary frame in a desired position, with no manual intervention on the blocking device.
- Door and window blocking devices are known, in very many shapes and types of application. All aim to allow the wings to be opened as desired and blocked in a certain position, so that draughts, or other accidental causes, cannot cause undesired movements of the wings, such as door and window slamming.
- German utility model Applications No. 1,899,327, No. 1,927,526, No. 75 15 214, No. 72 17 157 and No. 27 52 962 and from German patent applications No. 25 04 271 and No. 2940812 all aim to adjust the opening of doors and windows, but all require manual intervention whenever the position of the wings is to be changed.
- a door stop device is also disclosed in the German patent No. 574 789, in which the door wing can be stopped only in a position selected between few positions, by the engagement of a vertical pin, having a small upper head covered with felt and supported by the door wing with the interposition of a helical spring, and which engages the lower surface of a band rail bent according to a quarter of a helical turn of a vertical axis.
- the pitch of said helical rail can be varied according to a discrete number of lengths, for adjustment purpose of the wing stop position. In this case the stopping of said wing takes place only when the increasing frictional force attains a predetermined value.
- a US patent 1 560 960 corresponding to the preamble of claim 1 is also known, which discloses a stopping device, which comprises an arm connected at one of its ends,-to the door wing by means of a slot and stud assembly while the other end of which is pivotally connected to a threaded bolt, which is a part of a hinge device mounted in a casing supported by the stationary door frame.
- Said hinge device comprises a conical spring held against a washer by the wing nut of said threaded bolt, said washer being mounted on the bored end of said arm.
- the door wing can be stopped in any desired position only owing to the very modest frictional force created between the washer surface and the upper surface of the arm and, i.e. between two substantially smooth surfaces so that a little blast of wind could slam the door wing.
- the invention aims to realize a device as described in the above-cited literature, but which allows the wing of a door or window to be opened and closed without requiring manual intervention to stop said wing in any desired open position and which allows the door or window wing to be moved with no noise.
- the invention achieves this goal by realizing a very efficient frictional connection between the door or window wing and the respective stationary frame, where this connection is simultaneous with the movement of the wing and a direct locking effect, with no manual intervention, and where the frictional force of the device is adjustable, said frictional effect being due to a pair of frictional plates made of a material, as asbestos, capable of generating a high frictional effect and which is wear resistant.
- said frictional connection is realized by means of a hinge consisting essentially of two elements connected by a hinge headed bolt, the first of which is fixed to the frame of a door or a window, while the second one consists in an arm which can rotate about said bolt and is connected by means of a slot and stud assembly to the wing where said first and second elements are connected to one another for a relative rotary movement about said bolt.
- the invention provides the application on each side of said second element of a frictional disc made of a material capable of generating a high frictional effect and which is wear resistant or the like, as well as a bucket spring or the like placed in turn on the outer sides of each disc, while the bolt is provided of a threaded end portion to receive an adjustment nut.
- the fundamental concept of this first embodiment of the invention thus lies in the use of a frictional hinge device, which allows a door or window wing to be stopped almost silently in any desired position, from 0° to 180°.
- the most importance has the characteristics of the material to be placed between said first fixed element and said second movable element, which must satisfy the double requirement of generating a high friction effect and of showing a good wear resistance, preferably asbestos or the like.
- said elastic means consists of springs, preferably bucket springs, having their convex surfaces towards the outside of said first fixed element.
- the length of the slot in said second element must be at least equal to the distance between the rotation axis of the coaxial hinges of the door wing and the axis of the bolt of the frictional hinge, which is a part of the stopping device.
- the invention also provides that just above the bolt head, the bolt has a square portion, to be received into a complementary recess, arranges on the outer surface of the lower flange of two parallel flanges of said first fixed element. Such an arrangement prevents the bolt rotation.
- the material suitable for the first element forming the hinge device according to the invention may be selected from lightweight alloys, preferably aluminium, as well as from other materials, such as synthetic resins, satisfying the requirements for the construction of a hinge.
- said frictional connection between the door or window wing and the respective stationary frame is realized by a device comprising two parallel horizontal arms equipped with wear resistant frictional plates, fixed on a door or window wing which operates via friction along the entire 180° opening of said wing directly on a horizontal flange shaped in the form of a circular sector and connected to the door frame.
- said two arm assembly is realized in three variants:
- the member fixedly connected to the door or window frame i.e. the bar and the sector-like flange thereof are made of metal, preferably well polished, hardened, elastic steel, to allow application to the frame, optionally with the interposition of a spacer.
- the bar is applied at one side or at the opposite side of the circular sector flange, depending on whether it is applied to the right or left side of the stationary frame.
- Said sector will have a 180° center angle if the wing has to be entirely opened or about a 90° center angle, if the opening cannot exceed this value.
- the 90° flanges are also folded at an angle at the base, in one direction or the opposite one, depending on whether they are to be applied to the right or left side of the door.
- the radius passing through the mid-point of the 180° sectors or, respectively, through the point corresponding to a right angle of the 90° sectors, must always be perpendicular and coplanar with the axis passing through the provided hinges to enable a rotation of the wing with respect of the stationary frame.

Description
- The invention concerns a frictional locking device for stopping a door or window wing hinged to a stationary frame in a desired position, with no manual intervention on the blocking device.
- Door and window blocking devices are known, in very many shapes and types of application. All aim to allow the wings to be opened as desired and blocked in a certain position, so that draughts, or other accidental causes, cannot cause undesired movements of the wings, such as door and window slamming.
- However, these devices suffer from the inconvenience of requiring manual adjustment from time to time for a given open position of the sashes. This means that, once the open angle is established, the device effects the wing block by means of mechanisms comprising grooves, pins, screws, sliding clamps or analogous devices; therefore, varying the angle always requires manual handling of the device.
- For example, the devices known from the German utility model Applications No. 1,899,327, No. 1,927,526, No. 75 15 214, No. 72 17 157 and No. 27 52 962 and from German patent applications No. 25 04 271 and No. 2940812 all aim to adjust the opening of doors and windows, but all require manual intervention whenever the position of the wings is to be changed.
- A door stop device is also disclosed in the German patent No. 574 789, in which the door wing can be stopped only in a position selected between few positions, by the engagement of a vertical pin, having a small upper head covered with felt and supported by the door wing with the interposition of a helical spring, and which engages the lower surface of a band rail bent according to a quarter of a helical turn of a vertical axis. The pitch of said helical rail can be varied according to a discrete number of lengths, for adjustment purpose of the wing stop position. In this case the stopping of said wing takes place only when the increasing frictional force attains a predetermined value.
- A US patent 1 560 960 corresponding to the preamble of claim 1 is also known, which discloses a stopping device, which comprises an arm connected at one of its ends,-to the door wing by means of a slot and stud assembly while the other end of which is pivotally connected to a threaded bolt, which is a part of a hinge device mounted in a casing supported by the stationary door frame. Said hinge device comprises a conical spring held against a washer by the wing nut of said threaded bolt, said washer being mounted on the bored end of said arm.
- According to this solution the door wing can be stopped in any desired position only owing to the very modest frictional force created between the washer surface and the upper surface of the arm and, i.e. between two substantially smooth surfaces so that a little blast of wind could slam the door wing.
- In order to overcome said inconveniences of the devices of the prior art, the invention aims to realize a device as described in the above-cited literature, but which allows the wing of a door or window to be opened and closed without requiring manual intervention to stop said wing in any desired open position and which allows the door or window wing to be moved with no noise.
- The invention achieves this goal by realizing a very efficient frictional connection between the door or window wing and the respective stationary frame, where this connection is simultaneous with the movement of the wing and a direct locking effect, with no manual intervention, and where the frictional force of the device is adjustable, said frictional effect being due to a pair of frictional plates made of a material, as asbestos, capable of generating a high frictional effect and which is wear resistant.
- In a first embodiment of the invention, said frictional connection is realized by means of a hinge consisting essentially of two elements connected by a hinge headed bolt, the first of which is fixed to the frame of a door or a window, while the second one consists in an arm which can rotate about said bolt and is connected by means of a slot and stud assembly to the wing where said first and second elements are connected to one another for a relative rotary movement about said bolt. The invention provides the application on each side of said second element of a frictional disc made of a material capable of generating a high frictional effect and which is wear resistant or the like, as well as a bucket spring or the like placed in turn on the outer sides of each disc, while the bolt is provided of a threaded end portion to receive an adjustment nut.
- The fundamental concept of this first embodiment of the invention thus lies in the use of a frictional hinge device, which allows a door or window wing to be stopped almost silently in any desired position, from 0° to 180°.
- According to the invention, the most importance has the characteristics of the material to be placed between said first fixed element and said second movable element, which must satisfy the double requirement of generating a high friction effect and of showing a good wear resistance, preferably asbestos or the like. The invention also provides that said elastic means consists of springs, preferably bucket springs, having their convex surfaces towards the outside of said first fixed element.
- According to the invention, the length of the slot in said second element must be at least equal to the distance between the rotation axis of the coaxial hinges of the door wing and the axis of the bolt of the frictional hinge, which is a part of the stopping device.
- The invention also provides that just above the bolt head, the bolt has a square portion, to be received into a complementary recess, arranges on the outer surface of the lower flange of two parallel flanges of said first fixed element. Such an arrangement prevents the bolt rotation.
- Finally, according to the invention, the material suitable for the first element forming the hinge device according to the invention may be selected from lightweight alloys, preferably aluminium, as well as from other materials, such as synthetic resins, satisfying the requirements for the construction of a hinge.
- According to a second embodiment of the invention, said frictional connection between the door or window wing and the respective stationary frame is realized by a device comprising two parallel horizontal arms equipped with wear resistant frictional plates, fixed on a door or window wing which operates via friction along the entire 180° opening of said wing directly on a horizontal flange shaped in the form of a circular sector and connected to the door frame.
- The fundamental concept of this second embodiment of the device of the invention is still based on the force of friction, developed by a two arm assembly joined to a wing, directly on the sector-like flange extending outwardly from a horizontal bar joined to the stationary frame of a door or window.
- According to the invention, said two arm assembly is realized in three variants:
- - the first provides a pincer braking action of said two arms due to the presence of a helical expansion spring mounted between the outer ends of said arms, and the provision of an adjustment vertical threaded bolt with nut, acting as pivot pin;
- - the second provides the braking action in the presence of the threaded bolt only;
- - the third provides that said arms are hinged about a horizontal transversal pin and that the braking action by means of a replaceable spring.
- The member fixedly connected to the door or window frame i.e. the bar and the sector-like flange thereof are made of metal, preferably well polished, hardened, elastic steel, to allow application to the frame, optionally with the interposition of a spacer.
- The bar is applied at one side or at the opposite side of the circular sector flange, depending on whether it is applied to the right or left side of the stationary frame. Said sector will have a 180° center angle if the wing has to be entirely opened or about a 90° center angle, if the opening cannot exceed this value. The 90° flanges are also folded at an angle at the base, in one direction or the opposite one, depending on whether they are to be applied to the right or left side of the door.
- The radius passing through the mid-point of the 180° sectors or, respectively, through the point corresponding to a right angle of the 90° sectors, must always be perpendicular and coplanar with the axis passing through the provided hinges to enable a rotation of the wing with respect of the stationary frame.
- The advantages obtained with both embodiments of the present invention reside in the frictional connection of a door or window wing with respect of the respective stationary frame. Opening or closing the wing, the frictional hinge device or the pincer device enables to automatically stop the wing in any desired position along the entire opening arc in an absolutely silent fashion.
- The invention is described in more detail with reference to embodiments shown in the accompanying drawings, given merely in an exemplifi- cative and non-limiting way. The drawings, show; in
- Figure 1, a prospective view of the frictional hinge device according to the invention, applied to the frame and wing of a door;
- Figure 2, an exploded view of the individual component elements of the device of Figure 1;
- Figure 3, a detail in an enlarged scale, of the frictional device of Figure 1;
- Figure 4, a view from above of the elements of Figure 2 in assembled condition thereof;
- Figure 5, a perspective view of a door wing hinged to the stationary frame and provided with the pincer device equipped with adjustment hinge bolt and with an expansion spring for braking, and cooperating with a 180° sector flange of a bar, mounted on the right side;
- Figure 6, a view, similar to that of Figure 5 with the variant of the frictional pincer's device including an adjust-threaded bolt, and which cooperates with a 90° sector flange of the bar fixed to the frame;
- Figure 7, a view similar to that of Figures 5 and 6, with the variant of the pincer device including a replaceable expansion spring and cooperating with 90° sector flange, on the left side, of the first element.
- In Figure 1, the frictional locking device according to the invention includes a frictional hinge indicated generically with 1. Said device comprises a
bar 5 fixed to thestationary frame 2 of a door, and which is provided at one of its ends with two horizontal, vertically spaced away,flanges 5a. Asecond element 4 consists in a flat arm, having at one of its ends, alongitudinal slot 8 into whcih slides avertical stud 7 fixed to thewing 3 of the door. - In the case of
stationary frame 2 of the type of Figure 1, thebar 5 is fixed to theframe 2 with the interposition of aspacing member 13. The length of theslot 8 must be at least equal to the distance between the axis of thebolt 9 and theaxis 15 of the coaxial hinges enabling thewing 3 to rotate with respect to thestationary frame 2. - Figure 2 shows all the component elements of the frictional locking device in an exploded view. The pair of
horizontal flanges 5a of thebar 5 define a U-shaped housing or recess designed to receive the end portion of thearm 4, provided with avertical hole 9" coaxial with a square center recess 9' arranged with the twoflanges 5a. The hinge device 1 comprises abolt 9 having alower head 9a and an upper threaded end portion 9b for receiving anut 11 and awasher 10. - Thanks to the presence of a square recess 9' in each the
flanges 9a, thebolt 11 is prevented to rotate and it will be possible to use a hinge device 1 according to the invention, either for a left or for aright wing 3, that is, by having the threaded part 9b of thebolt 9 protruding upward so as not to interfere with the movement of the wing. - On two sides of the bored end of the
arm 4 twodiscs 6 are mounted made of a material capable of generating a high frictional effect and which is wear resistant as asbestos. Between eachdisc 6 and therespective flange 5a of thefixed bar 5 there is a spring 6' preferably a bucket spring, which is convex toward theadjacent flange 5a. The degree of tightening of thebolt 9 withnut 10 andwasher 11, in combination with the elastic deformation of theflanges 5a enables to regulate the pressure between theflanges 5a and thebar 4, pressure which in virtue of the action of springs 6' anddiscs 6 is apt to generate the elastic friction effect and so the locking of thewing 3, with almost no noise. - Figure 3 shows a detail of the frictional hinge 1.
- Figure 4 shows the frictional locking device when completed assembled.
- It would of course be possible to realize the frictional hinge 1 without springs, just by using the
asbestos discs 6, or one could use helical springs instead of bucket springs. - Another embodiments of the invention are illustrated in three variants shown in Figures 5, 6 and 7.
- In Figure 5 the stationary door frame is indicated with 101, the door wing with 102. This embodiment provides to use a pincer device generically indicated with E, comprising two parallel
horizontal arms lower arm 103 of the pincer device E is fixed withscrews 105 to thedoor wing 102 and has at one end a recess (not shown in the drawing) for anchoring the lower end of ahelical expansion spring 106 and, not far away, a vertical threaded hole (not shown in the drawing) for receiving the lower end of ascrew 107. Theupper arm 104 has a lower blind hole (not shown in the drawing) for anchoring the upper end of theexpansion spring 106 mounted coaxially to the blind hole of thearms 103, and a through hole 108 (not shown in the drawing), for the passage with a certain play of ascrew 107 which fits into the threaded hole of thelower arm 103 on the facing surfaces of thearms asbestos plates 109, 109' are applied with slightly protruding edges. Thespring 106 tends to lower the opposite end portions of theupper arm 104 of the pincer device toward thelower arm 103. Between the twoparts sector flange 111 enter extruding outwards from thebar 111, fixed to theframe 101 and consisting of well polished and hardened elastic steel. In this particular case, thearms spring 106 can be regulated by means ofscrew 107. The friction developed between theasbestos plates 109, 109' and thesemicircular sector flange 111 a is thus transmitted directly between thewing 102 and theframe 101. The elasticity of the steel of which thesector flange 111a compensates for any excessive tolerances due to assembly or to the settlement of the parts. - Figure 6 shows a variant. The pincer device E' still consists of a
lower arm 103 and anupper arm 104. Thelower arm 103 is fixed to thewing 102 withscrews 105. Theupper arm 104 is connected to thelower arm 103 only by means of an adjustingscrew 107, withwing nut 107a. A vertical guiding pin 107' extending upwards from thearm 103 and entering in a through hole of thearm 104 serves to prevent any mutual rotation between thearms flange 111 a' has the form of a 90° sector. - Figure 7 shows another variant. The pincer device E" still consists of a lower arm 103' and an upper arm 104'. The lower arm 103' is fixed to the
wing 102 of the door by means of screws 105', and is pivotally connected to the upper arm 104' by means of horizontal pin 113. Anexpansion spring 106 is .mounted between the outer ends of the arms 103', 104', while at the opposite endsasbestos plates 109, 109' frictionally engage the sector likeflange 111 a" of thebar 111. In this case the circular flange 11.1a" has a shape symmetrically equal to that of Figure 6. - The friction force depends upon the characteristics of the
spring 106, which is mounted in an amovable manner.
