ES2230922A1 - Height adjustable hinge - Google Patents

Abstract

The hinge consists of male (1) and female (2) components mounted on a hinge pin (3). The male component rests directly or indirectly on an external axial thrust bearing (5) fitted with washers (6) or shims to adjust the height of the female component relative to the male one. The hinge also has a spring in the form of an elastic ring (8) which is held under compression by a peg inserted through the male component and into a hole in the hinge pin.

Description

Hinge adjustable in height.

The present invention is about a new hinge adjustable in height, of which they consist of a physical axis mounted in a semi-part female and in which physical axis pivots a semi-male part

It is already known, and it is usual, the use of these reinforced hinges on heavy doors (for example on doors armored and / or armored).

The use of current reinforced hinges does not allows to correct clearances and / or mismatches when, either by use (with the passage of time) or by unevenness of work (in new or refurbished constructions) these gaps arise and mismatches, which result in door leaf chafing Against its frame. Nor do they allow prestressing between their semi-parts so currently once mounted hinges it is necessary to arrange other devices so that the Door or window store to be kept closed.

The hinge, according to the present invention, solves these limitations. Being of the type described it is characterized why:

a) consist of a physical axis mounted on a female half-part and in which physical axis pivots a semi-part male, characterized in that in said physical axis, and in correlation with the female half-part, it is arranged externally a bearing in which, directly or indirectly supports the male half part;

b) in correlation with said bearing, one or more self-locking washers / chock (s), which regulates (n) height the positioning between male parts and hinge female;

c) said physical axis implies a internal spring accessible by window in which it is positioned a pin also housed in a hole in the semi-male part to fix the physical axis in a tensioning position. Window of the physical axis is torn and conforms to the Theoretical transverse axis of the hinge to ensure its positional reversibility in right / left hinges;

d) in the male half part they form a plurality of aligned holes, in one of the which is the pin that, through its window torn, fixed to the physical axis in a position of tense

Additionally, at least one elastic washer that offers structural continuity between half-male / female hinge parts covering the physical axis in the interspace delimited by its different heights.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1a represents a general view in perspective of the hinge object of the invention, for an embodiment which exclusively compensates for gaps and / or mismatches.

Figure 1b represents an overview in similar perspective to figure 1a, for an embodiment that, It also allows prestressing.

In both figures all the components in assembly arrangement. For a perfect understanding must be understood mounted all the components in a same theoretical axis of symmetry (e1).

Figure 2a represents a general section schematic of the hinge, according to the embodiment of figure 1a.

Figure 2b represents a general section hinge schematic, according to embodiment of figure 1b, including the physical axis (3) with an internal spring (9) tensionable from an extreme head (3a) and with the window (31) of the physical axis (3) housing the pin (4) in she.

Figure 3 represents, in enlarged section, the bearing (5) and a washer / chock (6) arranged in correlation.

Figure 4 schematically represents a partial section, in enlarged detail, according to indication A: A of the Figure 2b, without pin (4) and with several holes (O1), (O 2), (O 3) in the male half part (1) of the hinge facing the window (31) of the physical axis (3).

An example of practical, non-limiting embodiment of the present invention.

The present invention concerns a hinge, of those that are structured in two semi-parts or sheets, one male (1) and another female (2) mounted on a physical axis (3).

According to the invention, the Semi-parts male (1) and female (2) are different height delimiting between them an amplitude (h) -which, preferably, it offers continuity in sight by including a spring washer (8) -.

The physical axis (3), meanwhile, it can be solid or hollow and, in case of being hollow, involve a internal spring (9) accessible through a window (31) in the that a pin (4) is positioned which, also housed in a hole (O_ {1}) of the male half-part (1), fixed to physical axis (3) in a tensioning position, pre-adjustable from an extreme head (3a) of a stopper (T1) -as in the embodiment of Figures 1b and 2b-.

In accordance with the invention, and according to any of the embodiments represented, in said physical axis (3), and in correlation with one of the arms of the female half-part (2), are arranged externally a bearing (5), on which it supports the semi-male part (1), either directly or indirectly, with interposition of at least one washer / chock (6), self-locking on the physical axis (3).

The bearing (5) -see figure 3- is structured in:

- a base cap (5_ {1}) that sits coaxially in one of the arms of the semi-female part (2) and axially supports the balls (5 3);

- a cap-cap (5_ {2}) coaxial with the base bushing (5_ {1}) on which it supports axially (inserting one or several washers / chock (6) when needed compensate for gaps or mismatches).

The sandstones / chock (6) are open (for insert them without removing the hinge) and autoblock on the physical axis (3).

The physical axis (3) involves a head (3a) that sets its travel stop in the assembly and fixed to the female half-part (2) by deformation, punching or any other solution.

A plug (T) closes the semi-part female (2) on the opposite side of the theoretical axis of symmetry (e1) that contains these coaxially mounted elements offering a finish and apparent symmetry for the hinge.

It is usual - and not the subject of the invention - to include bushing (s) (7) to facilitate free pivot between male (1) and female (2) parts of the hinge with respect to the physical axis (3), with minimal friction.

In accordance with the invention, and according to the embodiment depicted in figures 1b and 2b, the window (31) of the physical axis (3) is torn and through. Be conforms on a theoretical axis (e2) transverse to the theoretical axis of symmetry (e_ {1}) of the hinge; so that your positional reversibility: the same hinge according to the invention it can be used, interchangeably, in doors that close to right or left.

The male half part (1) forms at least one hole (O1) and, preferably, a plurality of holes (O_ {1}), (O_ {2}), (O_ {3}) aligned generatrially and likely to face, one or the other, the window (31) of the physical axis (3), to accommodate the pin (4) that fixes the physical axis (3) in a tensioned position - see figure 4-.

With this structure and arrangement the hinge offers minimal friction in opening and closing
- facilitated by bearing (5) and bushings
(7) -. Before an eventual friction, one -or several- washers / chock (6) is interposed until it is saved. The thickness of the washer (s) / wedge (6) is visually compensated by compressing the spring washer (8) without any conditioning within its elastic limit.
