Support device for handle closing system and the like

Description

[0001] The present invention relates to a support device for a handle closing system and the like, in particular for door closing systems including handles, of the type specified in claim 1.

[0002] Door closing systems are generally provided with a graspable handle and a support device suitable to support the handle on the door as described in patent applications GB-A-470358, DE-A-10200113, GB-A-445637, US-A-3708191.

[0003] Closing systems arranged on doors also frequently comprise a pair of handles with relative support devices. In fact, each side of the door comprises a handle and the two handles are mutually connected by means of a metal rod arranged inside a through hole, made inside the door.

[0004] The metal rod also preferably produces the constraint of the door closing system. Some support devices also comprise a return spring, suitable to return the handle to the correct position after use thereof.

[0005] In other cases said support devices do not include the return spring and therefore make use exclusively of the return spring that may be present inside the lock controlled by the system .

[0006] Due to numerous drawbacks and malfunctions this latter type of handle system has now become obsolete and is no longer chosen or marketed.

[0007] Nonetheless, support devices for closing systems comprising a return spring also have some important drawbacks.

[0008] In particular, they have a relatively high thickness protruding from the surface of the door.

[0009] This thickness is above all due to the presence of the return spring and correlated elements.

[0010] The support device is therefore an element that could possibly get in the way and cause accidents. In fact, a passing person could accidentally knock against it. Moreover, the considerable thickness has a relatively displeasing aesthetic appearance.

[0011] In this situation the technical aim of the present invention is to devise a support device for handle closing systems capable of substantially overcoming the aforesaid drawbacks.

[0012] Within said technical aim an important object of the invention is to obtain a support device which has a limited thickness protruding from the surface of the door.

[0013] The technical aim and the objects specified are achieved by a support device for handle closing systems as claimed in the appended independent claims.

[0014] Preferred embodiments are highlighted in the dependent claims.

[0015] Further characteristics and advantages of the invention are clarified below by the detailed description of a preferred embodiment of the invention, with reference to the attached drawings, wherein:

Fig. 1 shows the section I-I, indicated in Fig. 2, of the support device according to the invention;

Fig. 2 show the section II-II, indicated in Fig. 1, of the device according to the invention;

Fig. 3a shows a first variant of the section of Fig. 1;

Fig. 3b shows a second variant of the section of Fig. 1; e

Fig. 4 is an overall view of a handle including one of the support devices according to the invention.

[0016] With reference to the aforesaid Figures, the support device according to the invention is indicated as a whole with the number 1.

[0017] It is suitable to be part of closing systems 2 positioned on doors 20 and the like and commonly called "handles". In particular, the term door is preferably intended as a door 20 for people, i.e. suitable to allow people to pass through walls of buildings and the like, or can also be intended as doors of furniture, wardrobes, vehicle doors, windows for buildings and the like.

[0018] Moreover, the closing systems 2 are positioned in a hole 21 present in the door 20, and comprise a handle 3 and a support device 1.

[0019] Preferably, the closing systems comprise a pair of handles 3 as shown in Fig. 1, arranged on opposite sides of the door 20 and each connected to a relative support device 1, which are mutually connected by means of a rod 12 passing through the hole 21 and suitable to guide the lock. Alternatively, a single handle 3 can be provided.

[0020] The closing systems 2 are suitable to be controlled by the handle 3, through which opening and closing of the door 20 can be controlled.

[0021] The handle 3 is therefore movable with respect to the door 20 and in particular rotatable.

[0022] The support device 1 extends mainly along a plane 1a, preferably perpendicular to the direction of rotation of the handle 3 and parallel to the main extension plane of the door 20.

[0023] Summarily, it comprises a fixed element 4, suitable to be constrained solidly to the door 20, a movable element 5, suitable to support the handle 3 and connected to the fixed element 4 and movable with respect thereto, and a return mechanism 6 suitable to exert a return force opposing the relative movement of the elements 4 and 5.

[0024] In particular, the fixed element 4 comprises a first part 10 of a flange 8, suitable to support the device on the door 21 and, appropriately, an inner part 9 suitable to contain the movable element 5 and the return mechanism 6.

[0025] It also preferably comprises three holes 10a for support by means of screws or the like.

[0026] The flange 8 is then composed of a first part 10, being part of the fixed element 4, and a cover 11, constrainable to the first part 10 by interlocking.

[0027] The flange 8 also has an average outer diameter greater than or equal to the average outer diameter of the inner part 9 in the main extension plane 1a. Moreover, it can be square or circular in shape, or of yet other types.

[0028] The inner part 9 is instead preferably circular in shape, just as the movable element 5 contained therein, and the two elements are mutually constrained by forcible profiles 14.

[0029] The fixed 4 and movable 5 elements are also preferably provided with abutments for the return mechanism 6. In particular fixed abutments 13a are provided integral with the fixed element 4 and movable abutments 13b are provided integral with the movable element 5.

[0030] The return mechanism 6 is also appropriately an elastic element preferably realized by a circular spring.

[0031] Finally, the fixed element 4 comprises a limit stop abutment 13c for the movable element 5.

[0032] Moreover, a first portion 7 of the support device 1, comprising at least part of the return mechanism 6, is arranged inside the hole 21.

[0033] Preferably, the first portion 7 comprises the entire return mechanism 6 and at least part of the fixed element 4, and in particular the entire inner part 9, and at least part of the movable element 5. This solution is shown in Fig. 1.

[0034] In this case the hole 21 is preferably circular, or of different type, and with a constant diameter and of standard dimension in proximity of 35 mm, or greater. Alternatively, also the first part 10 of the flange 8 is arranged inside the hole 21, as shown in Fig. 3a.

[0035] In a different alternative, the entire flange 8 is arranged in the hole 21 and therefore the entire device 1 is inside the hole 21, as shown in Fig. 3b.

[0036] In these last two cases, the hole 21 includes a portion of greater diameter, or different shape, suitable to contain at least part of the flange.

[0037] The invention achieves important advantages.

[0038] In fact, the support device 1 has a limited thickness protruding from the surface of the door 20, or aligned therewith.

[0039] Moreover, this device 1 can be inserted inside holes 21 having standard diameters, or of different types, in particular in the field of doors, furniture and wardrobes.

[0040] The device 1 is therefore aesthetically pleasing and does not get in the way of passing people.

[0041] Moreover, it is simple and economical.

[0042] The invention is susceptible to modifications and variants falling within the scope of the claims. All the details can be replaced by equivalent elements and the materials, shapes and dimensions can be any.
