Description
- The present invention relates to a device for locking the door of vehicles.
- Nowadays, the doors of vehicles such as vans, lorries, trucks, etc, are typically provided with specific apparatuses, called undersill devices, which are capable of ensuring the stable locking of the rear door in the closed configuration of the inner compartment of the container, thus preventing the accidental opening thereof and at the same time allowing manual actuation by an operator who wants to have access to the compartment.
- In a substantially known manner therefore, such devices comprise first of all a base plate, which can be rigidly secured to the frame of the vehicle, below the door, and a further lamina (also called a "striker"), which in turn can be stably coupled to the frame of the vehicle, above the door (and substantially vertically aligned with the base plate).
- When the door is arranged in the closed configuration of the compartment, the base plate and the lamina can be respectively mated with a lever and a pawl element, which are keyed on opposite ends of a bar, which is rotatably supported by the door itself, for the stable locking of the door.
- In more detail, two side walls arise from the lamina, which support a transverse bar, underneath which a sort of appendage, elongated and curved, of the pawl element can be engaged, thus achieving the aforementioned mating.
- Such implementation solution is not however devoid of drawbacks.
- During movements of the vehicle, the door is subjected to various stresses, for example following the passage of the vehicle over potholes or bumps, or as a result of vibrations of various origin, and the like.
- Such stresses can thus cause slight movements and oscillations of the door (as a result of the plays and tolerances which are typically present between the respective connection elements), which naturally is in the closed configuration, with the pawl element mated with the lamina.
- Deviations of the pawl element from the ideal arrangement can evidently prejudice the correct operation of the locking device, compromising the quality of the mating and/or causing sticking or permanent deformations in the elements in play.
- It should furthermore be noted that the market in the sector increasingly requires implementation solutions that, while maintaining the qualitative and functional standards that the end consumer demands, offer ever-lower costs, in order to maintain the necessary competitiveness with a competition that is increasingly aggressive.
- Such need clashes with the tendency of makers of locking devices who, in order to prevent the problems owing to possible deviations of pawl elements (as explained above), offer solutions that are massive and heavy, which, although ensuring better resistance and stability, inevitably raise the end cost of the device.
- The aim of the present invention is to solve the above mentioned problems, by providing a device that is capable of achieving the locking of the door for closing the rear compartment of a vehicle of the type of lorries, vans, trucks, stably and effectively.
- Within this aim, an object of the invention is to provide a device that ensures the locking of the door for closing the rear compartment of a vehicle, while at the same time ensuring resistance to stresses and vibrations.
- A further object of the invention is to provide a device that enables the locking of the door, with a solution that is low cost.
- A further object of the invention is to provide a device that ensures a high reliability of operation and offers protection against attempts at forced entry.
- Another object of the invention is to provide a device that can be easily implemented using elements and materials that are readily available on the market.
- Another object of the invention is to provide a device that is safely applied.
- This aim and these objects are all achieved by a device for locking the door of vehicles, of the type of vans, trucks, lorries, semi-trailer trucks, trailers and the like, that comprises a base plate, which can be rigidly coupled to the frame of a vehicle, below a door thereof, and an abutment lamina, which can be rigidly coupled to the frame of the vehicle, above the door, said plate comprising retention means for a lever, which can be rigidly keyed on a first end portion of a bar that is rotatably supported by the door, said lamina comprising fastening means for a pawl element, which can be rigidly keyed on a second end portion of said bar, opposite to said first portion, said lever being rotatable from at least one first angular position, in which said lever and said pawl element can engage respectively with said plate and said lamina, respectively by way of said retention means and said fastening means, for the locking of the door so as to close the compartment, to at least one second angular position, in which said lever and said pawl element are disengaged from said plate and from said lamina, for the free movement of the door, and vice versa, characterized in that said pawl element comprises a curved appendage, which can engage by interlocking with said lamina, by way of said fastening means, at least two containment walls, arranged in a "V" formation, extending from said lamina and delimiting an accommodation seat for at least one portion of said pawl element, opposite said appendage, in order to prevent the movement, in any direction, of said pawl element, when said pawl element is engaged with said lamina.
- Further characteristics and advantages of the invention will become better apparent from the description of a preferred, but not exclusive, embodiment of the device according to the invention, which is illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
Figure 1 is a front elevation view of the locking device according to the invention; -
Figure 2 is a view from below of the pawl element; -
Figure 3 is a side elevation view of the pawl element; -
Figure 4 is a sectional view ofFigure 1 , taken along the line IV-IV; -
Figure 5 is a sectional view ofFigure 1 , taken along the line V-V. - With particular reference to the figures, the reference numeral 1 generally designates a device for locking the door of vehicles, of the type of vans, trucks, lorries, semi-trailer trucks, trailers and the like. More specifically, according to the preferred application, the device 1 enables the locking of the rear door of vehicles such as those mentioned above, which is placed so as to close an inner compartment intended for the storage and transport of various types of goods.
- Constant reference will therefore be made to such preferred application hereinafter, but the possibility is not ruled out of the use (which still comes under the scope of protection claimed herein) of the device 1 according to the invention in different applications, according to specific requirements.
- The locking device 1 comprises a
base plate 2, which can be rigidly coupled to the frame of the vehicle, below the door, and an abutment lamina 3 (also called a "striker"), which in turn can be rigidly coupled to the frame of the vehicle, above the door (and substantially vertically aligned with the plate 2). - The
plate 2 comprises retention means 4a, 4b for alever 5, which can be rigidly keyed on afirst end portion 6a of a bar (of which the aforementionedfirst end portion 6a and asecond end portion 6b, opposite the first, are shown schematically in dotted lines, inFigure 1 ), which is rotatably supported by the door. Similarly, thelamina 3 comprises fastening means 7 for apawl element 8, which can be rigidly keyed on thesecond end portion 6b of the bar. - In substantially known manner, the
lever 5 can rotate from at least one first angular position, in which thelever 5 and thepawl element 8 can engage respectively (as shown in the various accompanying figures) with theplate 2 and thelamina 3, respectively by way of the retention means 4a, 4b and the fastening means 7, in order to ensure the locking of the door in the closed configuration of the compartment, to at least one second angular position, in which thelever 5 and thepawl element 8 are disengaged from theplate 2 and from thelamina 3, for allowing the free movement of the door, and vice versa. - More generally, an operator can grasp the
lever 5, when the door is open, in order to pull the door into the closed configuration of the compartment, and, once such configuration is reached, he or she can lock the door by rotating thelever 5 until it is arranged in the first angular position (shown in the accompanying figures), in which it is stably engaged with theplate 2 and, integrally, thepawl element 8 is engaged with thelamina 3, thus preventing, from opposite sides of the door, the free movement (and accidental opening) of the door. - It should be noted that the
plate 2, the retention means 4a, 4b and thelever 5 can be provided in various ways, including conventional ones (and for example according to what can be seen in the accompanyingFigures 1 and5 ), and thus we will not linger further on such components. - Purely for the purposes of example, the possibility exists, illustrated in the accompanying figures, for the retention means 4a, 4b to comprise both an
arm 4a, below which acurved end flap 5a of thelever 5 can be inserted, and abutton 4b, which is normally arranged so as to interfere with the rotation of thelever 5, and which can be manually actuated in order to allow the rotation. - According to the invention, the
pawl element 8 comprises acurved appendage 9, which can engage by interlocking with thelamina 3, by way of the fastening means 7. - Moreover, extending from the
lamina 3 are at least twocontainment walls 10, arranged in a "V" formation, which delimit an accommodation seat for aportion 8a of thepawl element 8, opposite theappendage 9, so that movements, in any direction, of thepawl element 8 are impeded when the latter is engaged with thelamina 3. - In particular, as can be seen from the accompanying figures (for example
Figure 1 ), theportion 8a of thepawl element 8 has a shape that complements the accommodation seat delimited by thecontainment walls 10 arranged in a "V" formation. - Even more specifically, according to an embodiment of important practical interest, cited by way of non-limiting illustration of the application of the invention, the
pawl element 8 comprises acentral block 11, which is substantially cylindrical in shape; from the lateral surface of theblock 11 extends theaforementioned appendage 9 and, on the opposite side, theportion 8a of thepawl element 8 which has a shape that complements the accommodation seat. - As can be seen for example from
Figure 4 , the substantially cylindricalcentral block 11 has a throughcavity 12 into which thesecond end portion 6b of the bar can thus be inserted and stably coupled. - Conveniently (with further reference to
Figure 4 ), the lateral surface of the substantiallycylindrical block 11, which encircles thecavity 12, has an extremely scant thickness, so as to be able to thus contain the overall weight of theblock 11, and hence the costs associated with raw materials. - According to the preferred, but not limiting, embodiment, the fastening means 7 comprise two
side walls 13, which extend at right angles from thelamina 3 and which define a sort of support for across-member 14, which can engage by interlocking with the curved appendage 9 (in the arrangement in which such components are shown in the accompanying figures), in order to achieve the stable mating between thepawl element 8 and thelamina 3. - For the purpose of further containing the weight of the locking device 1 according to the invention (and the costs associated with raw materials), both the
lamina 3, and theside walls 13, are made of steel plate. - Conveniently, the
lamina 3 has at least onehole 15, which is capable of receiving a screw for fixing to the frame of the vehicle. - In particular, according to the preferred, but not limiting, embodiment of the application of the invention, the
lamina 3 has twoholes 15, which are longitudinally aligned and mutually spaced apart; onehole 15 is located between thecontainment walls 10, so that when theappendage 9 is engaged with thelamina 3, as can be seen inFigure 4 , thehole 15 will be located below thepawl element 8, which effectively prevents access to thehole 15, thus ensuring greater security against possible attempts at forced entry. - Operation of the device according to the invention is the following.
- The device 1 according to the invention can be easily actuated (by way of the lever 5), in order to lock the door of a vehicle in the closed configuration, by bringing the
lever 5 to the first angular position so as to engage it with theplate 2, and simultaneously securing thepawl element 8 to thelamina 3. - In such mutual arrangement, the presence of the
containment walls 10, and their particular shape, defines an accommodation seat that can effectively contrast and prevent any movements in any direction (for example, in more detail, the twoindividual walls 10 simultaneously prevent both horizontal movements and vertical movements, parallel to the plane of arrangement of the lamina 3). - Thus with two simple components, small in size (the two walls 10), it is possible to enable the locking of the door in a stable and effective manner, while at the same time ensuring resistance to stresses and vibrations which otherwise, by causing small shifts of the door, would tend to move the
pawl element 8 from the optimal position, with consequent malfunctions. - The reduced dimensions (and thicknesses) of the
walls 10 simultaneously ensure the possibility of providing a device 1 with a weight, and hence a cost, that are absolutely contained, and such result is moreover assisted (as pointed out in the previous pages) by the choice to make both thelamina 3 and theside walls 13 from steel plate, and also the limited thickness of the lateral surface of theblock 11, which encircles thecavity 12. - Finally, as has been seen, the choice to arrange at least one hole 15 (intended to receive screws to fix the
lamina 3 to the frame of the vehicle) in the interspace delimited by thewalls 10, renders thehole 15 itself inaccessible once thepawl element 8 is mated to the fastening means 7, and thus when the door is closed and locked by the device 1 according to the invention, thus ensuring protection and security against attempts at forced entry. - In practice it has been found that the device according to the invention fully achieves the intended aim, in that the use of a pawl element, comprising a curved appendage which can engage by interlocking with a lamina that can be coupled to the frame, with two containment walls, arranged in a "V" formation, delimiting an accommodation seat for at least one portion of the pawl element, prevents the movement, in any direction, of the pawl element, when the latter is engaged with the lamina, and thus makes it possible to provide a device that is capable of providing the locking of the door for closing the rear compartment of a vehicle, in a stable and effective manner.
- The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
- In the embodiments illustrated, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other embodiments.
- In practice, the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
