Definitions

  • the present invention relates to a handle closing device for fastenings of the type pointed out in the preamble of the first claim.
  • the invention relates to a closing device that is adapted to be operated by a handle and that enables or prevents movement of the fastenings, preferably door frames, thus allowing or preventing passage of a person or an object between two adjacent environments.
  • presently closing devices mainly comprise a lock assembly operating a bolt, two handles operating a spring latch and a pin disposed inside a hole formed in the fastenings.
  • the pin enables the handles to be constrained to each other and is connected to the spring latch.
  • the devices are usually provided with supporting structures, suitably disposed at said hole, which enable the handles to be arranged in the right position and to regulate movements thereof.
  • Each supporting structure comprises a return spring adapted to bring the handle back to the right position after use, an attachment support disposed on the through hole and secured to the fastenings through screws, and a covering plate placed externally of the fastenings so as to conceal the return spring and the support to the sight, as well as the pin and the elements connected thereto.
  • a first important drawback can be found in that, due to the necessity to carry out complicated and accurate mounting operations, there are high cost for manpower at the installation or replacement of the fastenings and, in particular, of known closing devices.
  • the covering plate constitutes a possible hindering element and therefore a possible source of accident for a passer-by that is not careful. Above all the high protruding thickness of the covering plate gives an aspect of poor quality to the fastenings.
  • patent EP 2264262 A1 therefore cannot be used in the presence of standard through holes and further working is required to increase the sizes of said through holes.
  • Another important aim of the invention is to produce a handle closing device that can be easily mounted on any fastenings, irrespective of the sizes of the through hole.
  • the handle closing device for fastenings according to the invention is generally denoted at 1.
  • the closing device 1 is suitable to be placed in register with a housing hole 10a formed in 10 and, preferably, is at least partly disposed inside the housing hole 10a.
  • the closing device 1 comprises at least one handle 20 disposed at an outer surface 10b of a door 10 and adapted to enable an operator to actuate device 1, a lock 30 enabling or preventing fastenings 10 from being moved; at least one transmission rod 40 for transmitting motion between the handle 20 and lock 30; and at least one supporting apparatus 50 adapted to support handle 20 and to be at least partly housed in hole 10a.
  • the closing device 1 can have one lock 30, two handgrips or handles 20 disposed on opposite outer surfaces 10b of fastenings 10, two supporting apparatus 50, each of which is adapted to support one of handles 20 and a single transmission rod 40 adapted to mutually connect said components so as to enable an operator to actuate lock 30 with each of handles 20.
  • device 1 contemplates one lock 30, one handgrip 20, one supporting apparatus 50, and one transmission rod 40 adapted to connect such components with each other.
  • hand is used to identify any element defining a handgrip through which the operator is able to easily actuate lock 30 such as a lever handgrip, or a knob, for example.
  • Lock 30 is defined by a mechanism of the mechanical or electronic type, preferably of the mechanical type that, based on handle 20, defines a closed configuration and an open configuration.
  • the closed configuration lock 30 creates a constraint between fastenings 10 and a wall, door-case, or other similar structure; in the open configuration lock 30 does not create such a constraint.
  • Lock 30 preferably consists of a spring latch lock, i.e. it has an element that can be moved by handle 20 in such a manner that, when lock 30 is in the closed configuration, it protrudes from fastenings 10 and engages with said structure while, when lock 30 is in the open configuration it is almost fully housed in fastenings 10 enabling movement of the latter.
  • lock 30 is a spring latch bolt lock.
  • the closing device 1 has the transmission rod 40 suitably fixed to the handle 20, the supporting apparatus 50 and the lock 30 by means of friction fits, screws or other similar solutions so that passage of motion between these components is allowed.
  • the transmission rod 40 consists of a body defining a substantially straight major extension direction 40a preferably having a polygonal section and, more preferably, a substantially square section.
  • the supporting apparatus 50 comprises a return mechanism 51 adapted to exert a return force against the motion of handle 20; a first casing 52 adapted to be secured to the transmission rod 40 and therefore to handle 20; a second casing 53 suitable for engagement in a motion-admitting manner with the first casing 52 so as to enable relative motion between them; a stop limit 54 defining an abutment for limiting the relative motion between casings 52 and 53; and a hooking body 55 adapted to be rigidly secured to both the second casing 53 and fastenings 10.
  • the two casings 52 and 53 are adapted to be mutually connected, by friction fit for example, thus creating a box-shaped element 56 defining an inner chamber inside which the return mechanism 51 is housed.
  • casings 52 and 53 are adapted to be secured in such a manner that they can be mutually moved and preferably in such a manner that they can be mutually rotated about an axis substantially coincident with the major extension direction 40a.
  • Housed inside the inner chamber is the return mechanism 51 that, working against the action of handle 20, is able to store and release energy by exploiting rotation of the first casing 52 operated by handle 20 through the transmission rod 40.
  • lock 30 moves to the open configuration
  • the return mechanism 51 bucks the motion of the transmission rod 40 and therefore of handle 20 and stores energy
  • lock 30 goes back to the closed configuration
  • the return mechanism 51 releases this energy bringing the rod 40 and handle 20 back to the starting position
  • the return mechanism 51 comprises a spring or other similar element adapted to store energy based on displacement of the first casing 52 relative to the second casing 53.
  • it comprises a spring, preferably a torsion spring and, more preferably a torsion spring with at least three coils, adapted to store and release energy based on rotation of the first casing 52 substantially around the major extension direction 40a.
  • casings 52 and 53 have two openings that at the moment the box-shaped element 56 is formed overlap each other defining a slot 56a in which the ends 51a of the torsion spring are placed so that, as better described in the following, rotation of the first casing 52 relative to the second one 53 brings about mutual rotation of the ends 51 a of the torsion spring and therefore actuation of the return mechanism 51.
  • the first casing 52 is secured to the transmission rod 40 so that it is moved by handle 20, while the second casing 53 is rigidly fixed to fastenings 10 through the hooking body 55 so that it remains substantially stationary during rotation of handle 20.
  • the first casing 52 is secured to the transmission rod 40 by friction fit and therefore has a through cavity 52a at least partly conforming to the shape of rod 40 so that said friction fit can take place.
  • the through cavity 52a has a substantially circular section provided with cuts for engagement, by friction fit, with the transmission rod 40.
  • the through cavity 52a has a circular section of diameter substantially coincident with the side of the square section of the transmission rod 40 and at the vertices having cuts suitable for engagement, by friction fit, with the edges of said square section, as shown in Fig. 2 .
  • Constraint of the second casing 53 to the hooking body 55 is carried out by friction fits and therefore the second casing can be provided with ridges 53a, ribs or other similar elements that, protruding from the second casing 53 allow it to be secured to the hooking body 55.
  • the hooking body 55 comprises an outer portion 55a adapted to be rigidly secured to the outer surface 10b at the housing hole 10a; and an inner portion 55b suitable for rigid engagement with the second casing 53 and characterised by lower bulkiness than the outer portion 55a, so that it can be at least partly arranged in the housing hole 10a.
  • the outer portion 55a and the inner one 55b substantially define two lying planes distinct from each other.
  • portions 55a and 55b define two distinct planes substantially parallel to each other so as to enable the outer portion 55a to be substantially arranged at the outer surface 10b and the inner portion 55b to be substantially arranged inside the housing hole 10a, so that the box-shaped element 56 can be at least partly and preferably fully placed inside hole 10a.
  • the outer portion 55a and the inner one 55b are secured to the fastenings 10 and the second casing 53 by friction fits, screws, glues or other similar connecting means adapted to create a rigid and fixed constraint.
  • the inner portion 55b is secured to the second casing 53 by friction fits, while the outer portion 55a is secured to the fastenings 10 by screws.
  • the closing device 1 for fastenings can comprise one or more coatings 60 each of which is adapted to cover a supporting apparatus 50 and in particular to be fixed to the hooking body 55 on the opposite side relative to fastenings 10 so as to conceal apparatus 50 to the sight, as shown in Figs. 1 a and 1 b.
  • Coating 60 can consist of a suitably shaped plate adapted to be fixed to body 55 at the outer portion 55b through friction fit, screws, glues or other similar solutions.
  • coating 60 is adapted to be fixed to the outer portion 55b by friction fit.
  • the invention also concerns a type of fastenings 10, preferably consisting of a door, comprising the previously described closing device 1.
  • the closing device 1 is mounted on fastenings 10.
  • the operator disposes the return mechanism 51 between casings 52 and 53 and therefore forms the box-shaped element 56 securing casings 52 and 53 to each other in a motion-admitting manner.
  • the operator rigidly fixes the hooking body 55 to fastenings 10 causing the outer portion 55a to be disposed on the outer surface 10b and the inner one 55b to be housed inside hole 10a.
  • the operator through a suitable inlet present in fastenings 10 introduces the lock 30 in register with hole 10a, engages the transmission rod 40 with lock 30 and the first casing 52 and then terminates mounting of device 1 by engaging the coating 60 by friction fit with the hooking body 55 at the outer portion 55a and by locking handle 20 to the transmission rod 40.
  • handle 20 that is linked to the first casing 52 through the transmission rod 40, causes rotation of the first casing 52 relative to the second casing 53.
  • lock 30 When the first casing 52 abuts against the stop limit 54 and handle 20 stops its rotation, lock 30 has reached the open configuration and therefore the operator is able to move the fastenings 10.
  • the return means 51 releases the stored energy making the first casing 51, transmission rod 40, and handle 20 rotate relative to the second casing 52, around the direction 40a causing return of lock 30 to the closed configuration.
  • the invention achieves important advantages.
  • a first important advantage resides in that the closing device 1 can be easily mounted on any type of fastenings irrespective of the size of the hole.
  • the sizes of the supporting apparatus 50 can be adapted to those of the housing hole 10a. In detail, this possibility is obtained by exclusively varying the sizes of the hooking body 54 and leaving the box-shaped element 56 and the rest of device 1 unchanged.
  • the closing device 1 can be adjusted in a simple and quick manner to any fastenings 1 without complicated and expensive replanning of the supporting apparatus 50 being required.
  • this aspect is further advantageously ensured by the conformation of the box-shaped element 56 that not only enables said element to be secured to a hooking body 54 of any size, but is also characterised by very reduced sizes and therefore reduced bulkiness so that the element can be easily introduced into any hole 10a.
  • Another important advantage resides in that, since the box-shaped element 56 can be almost fully housed inside hole 10a, the obtained device 1 is characterised by a very reduced portion protruding from the outer surface 10b, which gives the device a high aesthetic quality.
