Handle locking systems

Field of the invention

This invention, which pertains to the field of mechanical engineering, addresses handle locking systems, more specifically for use in household appliances, doors or drawers.

Invention History

A handle, also called a flap, wing, handle or handle, is part of a connecting handle for an object that can be moved or handled. The design of each type of handle involves substantial energy issues, even when they are considered intuitively or following a tradition. The three general requirements for its design are: (i) sufficient strength to support the object or ability to transmit the force involved in the task for which the handle was designed; (ii) long enough to allow the hands to hold it and exert such reliable force; and (iii) circumference sufficiently small to allow the hands to wrap around it sufficiently to exert such force. Thus, there is a need for reliable interaction between the puller and the element or object to which it is integrated to permit its use. displacement.

It can be seen in the current art the fixation of said knobs by means of screws or the like, such as rivets or adhesives. The proposed invention suggests a safe, practical and resistant way of circumventing this obligation by means of an innovative positioning, locking and fixing system.

Detailed Description of the Invention

This invention outlines handle locking systems (1) characterized in their preferred configuration according to figures 4A to 4G by providing for the attachment of the knobs (1) to the door (2) of the appliances by means of independent inserts (12). , fitted with locking and locking, which fit into housings (13) in the backplate (11) disposed internally to the door (2) and concurrently in handle housings (15). Such inserts (12) have such a geometry that they fit in a specific position in order to avoid assembly errors. They are equipped with lateral projections (10) of different lengths, as shown in figure 4F. The backplate (11) is provided with a plurality of stops (16) to limit the end point of the insert (12) after engagement and also to prevent unwanted rotation in the opposite direction. There is also an insert locking groove (12). The handles (1) provide an access (21) to disable the lock (18) in case of disassembly of the handle (1). The lock (18) prevents the handle (1) from undesirable displacement of its final position. Said inserts (12) are an integral part of the assembly, projecting longitudinally from the ends that interact with the doped surface (2). In this way, the inserts (12) pass through the wall of the door (2), through holes (20) provided for this purpose, reaching the internal counter plates (11), in which they interact with the corresponding socket - in this case, the holes (20) on the counter plates (11) for pin fitting.The handle (1) is mounted to the door (2) by sliding vertically from top to bottom on the freezer door (2) and from bottom to top on door (2) of the cooler, has stops (16) to prevent unwanted rotation of the pin (12) in the wrong direction and also slots for locking the pin (12) .The backplate (11), in its preferred configuration , is arranged in a single piece and is provided with clicks (22) to prevent its vertical movement.

In another configuration, as shown in Figure 1, the knobs (1) are fixed to the door (2) or the drawer (2) of the appliances by means of slotted pins (4) fitted with locking and locking that fit into holes -sided in plates (3) disposed internally at the doors (2). Said cracked pins (4) are an integral part of the knobs (1), projecting longitudinally from the ends that interact with the surface of the door (2). In this way, the slotted pins (4) pass through the door wall (2), through holes provided for this purpose, reaching the internal plates (3), where they interact with the corresponding socket - in this case, the holes on the plates (3) to fit the pins.

In a different configuration, as shown in Figure 2, the handles (1) are provided with internal slots (7) at both ends, complementing the slots (6) of the locking devices (5) housed in the door (2), to which the knobs (1) engage by sliding vertically relative to the longitudinal axis of the locking devices (5), which are an integral part of the inner plate (3), projecting perpendicular to the plane of the inner plate (3). Such devices are provided with slots of the locking device (6) complementary to the slots (7) of the handle internally disposed at the ends of the knobs (1), providing the perfect fit between the parts. A lock (8) on each of the locking devices (5) interacts with the handle (1) at the end of the vertical sliding stroke, promoting full attachment of the handle (1).

In an additional configuration, as shown in Figure 3, the handles (1) extend to the door by means of a swiveling bracket (9) providing side projections (10) for locking and locking and subsequent locking in a slotted locking device (5) at the opposite end after turning around the axis of the swivel (9). The locking device (5) has a small lock (8) to secure the handle (1) to the door (2). In this configuration, the swivel (9) is an individual element attached to the inner plate (2) and provided with side projections (10) acting as snap elements with the corresponding snap (11) on the handle (1).

Once the swivel bracket (9) is fitted with the knob (1), the knob (1) is rotated about the swivel bracket shaft (9) and the knob fitting (11) is promoted (1). ) with the lateral projections (10), providing a first fixation. Additionally, the opposite end of the puller (1) engages vertically with respect to the longitudinal axis of the slotted locking device (5), also provided on the inner plate (3) and an integral part thereof. Such a device (5) extends perpendicular to the plane of the inner plate (3) extending across the outer surface of the door (2). The side grooves (6) provided about their axis interconnect with the corresponding grooves (7) of that puller end (1) that moves from the handle turn (1), so that it provides a second handle fit (1), while a lock (8) secures the handle (1) to the locking device (5), thereby promoting the attachment of the handle (1) to the door (2).

Thus, it is noted that in any anticipated variations of the fastening system there is a plate internally housed in the door or drawer, which contains a plurality of externally allocated handle, seat, lock and projections for engaging and locking.

Therefore, it is noticed that the proposed locking system is original in relation to the state of the art by proposing a fixation model based on studs and locking devices, without the use of fastening screws.
