Abstract

The present invention proposes locking mechanism body (11) with a housing (30) having a recess (13) within which a front handle body (14) extends in a manner to be rotatable to lock and unlock said locking mechanism. A transmission element (23) extending to the rear side of said front handle body (14) is joined to the front handle body so as to slidably drive a rear side actuator element on a guiding body (18), the actuator element being connected to a main rotary driver (24) by means of a connection lever. Said main rotary driver (24) is rotated by said connecting lever against the force of a restoring spring. It is connected to a plurality of flap locks (27). Said actuation member, on the other hand, drives a plurality of auxiliary drivers (30) by means of connections rods (31), which are in turn operating flap locks (27).

Description

Technical Field of the Invention

The present invention relates to a locking system operating a plurality of luggage compartment flap locks in buses.

Background of the Invention

Devices for operating a plurality of luggage compartment flap locks in buses are known in the art. Those devices are designed in the manner to operate a plurality of locks at the same and to enable access to operate the mechanism from inside the compartment. This is desired as such compartments provide sleeping space for drivers.
There are a number of patents/patent applications in the present field. Among others, EP 1 950 367 A1 , which is a European patent application of the present applicant, disclosing a similar locking mechanism in terms of the final elements such as the connection lever and the main rotary driver is of relevance.
The locking device according to the present invention provides an improved locking feature such that upon locking said mechanism, the outer handle is still operable so that a user may operate the handle by pushing the same without any interference with the locking mechanism. This may especially be advantageous when a user unintentionally attempts to force the handle for opening the luggage compartment. A handle displaceable but inactive in terms of driving the locking/unlocking mechanism prevents the user from exerting an unproportionate force with the expectation to open the compartment as the handle which is displacing much smoother in unloaded state will let him/her notice that the compartment is locked and reduce the pressure at his/her hand.
The locking device according to the present invention is also suitable for operating up to six locks from inside and outside the compartment. It therefore provides a flexible locking mechanism adaptable to a variety of configurations required by different bus models.

Objects of the Invention

Primary object of the present invention is to provide a luggage compartment locking mechanism having a handle operable without any interference with the locking mechanism, i.e. displaceable but inactive in terms of driving the locking/unlocking mechanism.
Another object of the present invention is to provide a luggage compartment locking mechanism suitable for operating up to six locks from inside and outside the compartment respectively, ensuring a flexible locking mechanism adaptable to a variety of configurations required by different bus models.
Another object of the present invention is to provide a luggage compartment locking mechanism in which an easily mountable inner handle structure capable of directly driving means for unlocking flap locks is used.

Summary of the Invention

The present invention proposes locking mechanism body with a housing having a recess within which a front handle body extends in a manner to be rotatable to lock and unlock said locking mechanism. A transmission element extending to the rear side of said front handle body is joined to the front handle body so as to slidably drive a rear side actuator element on a guiding body, the actuator element being connected to a main rotary driver by means of a connection lever. Said main rotary driver is rotated by said connecting lever against the force of a restoring spring. It is connected to a plurality of flap locks. Said actuation member, on the other hand, drives a plurality of auxiliary drivers by means of connections rods, which are in turn operating flap locks.

Detailed Description of the Invention

Referring now to the figures outlined above, the present invention proposes a locking mechanism body (11) on a housing (30) having a recess (13) within which a front handle body (14) extends in a manner to be rotatably movable around an axle (40). Said front handle body (14) can be rotated around said axle (40) by way of manually pushing any of the two planar regions (50) extending around a reflector portion (60). Said front handle body (14) automatically restores its original position upon release by means of a spring arrangement (not shown) provided in association with said axle (40).
A transmission element (23) extending to the rear side of said front handle body (14) is joined to the front handle body (14) so as to drive a rear side actuation mechanism as explained below. Said transmission element (23) is pivotally coupled to the rotatable front plate (14) through a spring element (not shown) such that while pushing the upper planar region (50a) inwardly displaces said transmission element (23) in the downward direction, pushing the lower planar region (50b) has no effect on the same as its displacement is prevented by a longitudinal lock guide (15).
Said longitudinal lock guide (15) is arranged such that it longitudinally displaces to enable said transmission element's (23) tip bear against a retaining means (17) Said retaining means (17) is designed to be a tubular T-form body (Fig. 2) telescopically engaging with a tubular-form actuator guiding body (18). Longitudinal displacement of said longitudinal lock guide (15) in linear directions A-B as in Fig. 2 provides rotation of said tubular-form actuator guiding body (18) around its longitudinal axis as its upper circumferential area (19) has threads engaging with inner threads of a closed region (20) of said longitudinal lock guide (15). Rotation of said tubular-form actuator guiding body (18) also rotates said tubular T-form body (17) upon which said retaining tips (17) rotates to bear against said transmission element (23) or releases movement of said transmission element (23). Lower arrows in Fig. 2 illustrate rotation of said retaining means (17).
When said tubular T-form body (17) is aligned to face said transmission element (23), displacement of said transmission element (23) moves an elevator element (21) which is guided on said tubular-form actuator guiding body (18). Said elevator element (21) being pivotally connected to an actuator lever (22) therefore rotates the main rotary driver (24) itself around the rotation axis (25) of said actuator (24).
Said main rotary driver (18) according to the present invention, can either be rotated by said actuation lever (22) or by an inner handle (23) as shown in Fig 4.
Connection slots (26) being placed around both sides of said main rotary driver (24) are used for connection with flap locks (27). Said main rotary driver (18) is therefore connected to a plurality of flap locks (27) by means of connections rods (28).
Said main rotary driver (18) is rotated by said connecting lever (22) against the force of a helical restoring spring (not shown) set up on the axis of said main rotary driver (18).
Said connection lever (22) comprises additional slots (29) for connection to auxiliary driver mechanisms (30) via vertical connection rods (31).
Said longitudinal lock guide (15) according to the present invention can also be displaced by means of a key inserted into the keyhole. Rotation of a keyhole device (32) moves said longitudinal lock guide (15) longitudinally back and forth by way of a keyhole device rear protrusion (33) being disposed in a cavity (34) of said longitudinal lock guide (15) as indicated in Fig. 2.
In a nutshell said luggage compartment locking mechanism (11) operates a plurality of flap locks (27). It comprises a housing (30) having a front handle body (14) associated with a transmission element (23) mechanically joined to said front handle body (14) to transmit displacement of said front handle (14) to a rear-side actuating mechanism comprising a rotary driver (24) driving a plurality of connection rods (28) associated with said flap locks (27). Said rear-side actuation mechanism comprises a longitudinal lock guide (15) displacing to selectively enable a retaining means (17) associated with an actuator guiding body (18) bear against said transmission element's (23) tip portion to drive said rotary driver (24) whereby said transmission element's (23) tip portion is allowed movement when said retaining means (17) is not aligned to bear against tip portion.
