Abstract
Description
- The present invention relates to a support for a rotating bar for actuating a device for opening and closing the door of the body of trucks, trailers and the like.
- The bar for actuating devices for opening and closing doors of truck bodies, of the lever or handle type, is traditionally rotatably associated with the door by means of supports that are substantially constituted by two contoured metal plates, which are coupled to each other so as to form a cylindrical longitudinal through seat for the bar. These metal plates are generally fixed to the outer surface of the door by means of four screws, which engage in a corresponding number of through holes provided at the corners.
- Such supports are not free from drawbacks. First of all, fixing to the door is generally provided, due to cost reasons, without using sufficiently precise equipment (for example numeric control drilling machines): accordingly, the drilling references are rather approximate and the centering of the bar with respect to the supports is consequently problematic.
- Secondly, international customs regulations related to the transport of goods with trucks, heavy goods vehicles and the like require, as is known, the external components of the device for opening and closing the door to be fixed to said door with solutions that ensure that any break-in attempts leave visible marks that are evident to customs officers. With particular reference to conventional bar supports, the four screws mentioned above must be properly welded to the metal plates, so that any attempt to remove the supports in order to disengage the bar from the door so as to open it requires cutting the welds, accordingly leaving an evident mark. This clearly entails an excessive expenditure of time as well as laborious and disadvantageous assembly.
- Thirdly, conventional supports are far too bulky and therefore the need is felt to achieve a reduction of the overall dimensions of the item.
- The aim of the present invention is to provide a support for the rotating bar for actuating the device for opening and closing the door of the body of trucks, trailers and the like that obviates the drawbacks mentioned above, i.e., is simple to assemble and allows effective centering and reference of the bar.
- Within this aim, an object of the present invention is to provide a support that has the requirements specified by customs regulations concerning the transport of goods on trucks, heavy goods vehicles and the like, i.e., is built so that it cannot be removed or disassembled without leaving evident tampering marks that are clearly visible to customs officers.
- Another object of the present invention is to provide a support that at the same time has a compact appearance and is extremely versatile, i.e., is adapted to be fitted to any type of car or truck.
- Another object of the present invention is to provide a support that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
- This aim and these and other objects that will become better apparent hereinafter are achieved by the present support for a rotating bar for actuating a device for opening and closing the door of the body of trucks, trailers and the like, characterized in that it comprises a base, which forms a longitudinal seat for accommodating and rotatably supporting the bar, which is fixed to the door by means of connecting elements engaged in at least one through hole provided substantially along the centerline; first and second substantially tubular elements, which are detachably associated with said base at the ends, so as to retain said bar in said seat; end abutments and at least one central spacer, which are suitable to lock said first and second elements at said ends of said base, said central spacer being rigidly coupled to said base by way of break-in resistant fixing means.
- Further characteristics and advantages of the present invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment of a support according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
- Figure 1 is a perspective view of a first embodiment of the support according to the invention;
- Figure 2 is a perspective view of the support of Figure 1, from which the protective cover has been removed;
- Figure 3 is a top view of the support according to the invention in the position for fitting to the door;
- Figure 4 is a partially sectional top view of the support;
- Figure 5 is a sectional view of the support, taken along the line V-V of Figure 3;
- Figure 6 is a sectional view of the support, taken along the line VI-VI of Figure 4;
- Figure 7 is a perspective view of a second embodiment of the support according to the invention;
- Figure 8 is a rear view of the support of Figure 7;
- Figure 9 is a partially sectional side elevation view of the support of Figure 7.
-
- In the embodiments that follow, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other embodiments.
- Moreover, it is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.
- With reference to Figure 1, the reference numeral 1 generally designates a support for a rotating bar for actuating a device for opening and closing the door of the body of trucks, trailers and the like according to the invention.
- Such bar is usually connected to a lever or handle for manual actuation of the door opening and closing device and is provided at its ends with sorts of pawls, which can engage respective abutments rigidly coupled to the frame of the body when the device is in the closure configuration.
- The support comprises a base, generally designated by the
reference numeral 2, which can be fixed to the door of the body of the truck, particularly on its outer face, and forms alongitudinal seat 3 for accommodating and rotatably supporting the cylindrical bar, which is not shown in the figures for the sake of simplicity since it is of a known type. First and second substantiallysemitubular elements base 2 and are adapted to retain the bar in thelongitudinal seat 3. -
End abutments 6 are provided in thebase 2 for the first and secondsemitubular elements base 2, protruding outward; there is also acentral spacer 7, which is suitable to prevent the movement of the first andsecond elements base 2. - Advantageously, the
spacer 7 is rigidly coupled to the base by way of break-in resistant fixing means, generally designated by thereference numeral 8. - The first and second
semitubular elements spacer 7 are conveniently surmounted by aprotective cover 9, which is detachably associated with thebase 2. - The
base 2, preferably made of steel plate, is constituted by a substantiallyflat portion 10, which forms twosides 11, and is open at the remaining sides. Theflat portion 10 forms in relief a plurality of substantially concave saddle-shaped surfaces 12 for supporting the lateral surface of the bar. Thesides 11 are affected by pairs of substantiallyrectangular openings 13. - The
flat portion 10 of thebase 2 is affected by twoholes 14, which are provided along the centerline (Figure 6) and are adapted to fix the support to the door by means of bolts or other equivalent screw elements. Advantageously, said screw elements are in no way accessible from the outside for any break-in attempts, since they are closed within theseat 3. Moreover, theflat portion 10 is affected by four holes 15 (clearly shown in Figure 8, which relates to the second embodiment of the support), the function of which will become better apparent in the continuation of the description. - The first and second
semitubular elements parallel lugs 16, shown in Figure 5, each forming a sort of slightly raised circumferential band 17 (Figure 2). - The first and second
semitubular elements cylindrical antifriction bush 18, which is keyed along the bar. Eachbush 18 is open along a generatrix and has internal and external lateral surfaces that are crossed by respective substantially uniform distributions oflongitudinal grooves 19, which formribs 20 for contact along the outer surface of the bar and the internal surface of thesemitubular elements bushes 18 further forms an outer raisedportion 21, which is suitable to engage within thecircumferential band 17, so as to achieve axial locking of thebush 18. - The
central spacer 7 is made of thin bent metal plate (Figures 2 and 4), so as to be substantially arc-like; the break-inresistant means 8 for fixing thespacer 7 to thebase 2 are advantageously constituted by two protrudingnotches 22, which are provided at the ends of the spacer and are suitable to engage withinrespective cutouts 23 provided in thesides 10 of the base 2 (Figure 4). Thenotches 22 are locked in thecutouts 23 by welding, so that any break-in attempt aimed at disassembling the supports in order to remove the bar and open the door of the truck is clearly evident. - The
end abutments 6 for the first and secondsemitubular elements sides 11 at theopenings 13, so as to form sorts of undercuts against which thelugs 16 abut (Figures 2 and 5). - The
protective cover 9 has a substantially arc-like transverse cross-section and is provided internally with two longitudinal parallel ridges 24 (Figure 3), which are inserted between the first and secondsemitubular elements sides 11. Thecover 9 is detachably associated with thebase 2 by way of four elastically flexiblelower tabs 25, which form respective teeth 26 (Figure 5), which are adapted to engage below the end edges of the first and secondsemitubular elements openings 13. - The method of use of the support according to the invention and its assembly on the outer surface of the door occur as follows: since the
holes 14 lie along the centerline of thebase 2 and therefore below the bar, thus achieving the considerable advantage described above with reference to break-in attempts, the drilling references for providing theholes 14 are advantageously formed by using the fourholes 15. - The
bushes 18 are keyed along the bar, which is then rested precisely on theconcave surfaces 12; then the first and secondsemitubular elements base 2, and are then made to slide toward the ends, so that thelugs 16 abut against theend abutments 6. At this point, thespacer 7 is fitted, again frontally, inserting with a snap action thenotches 22 in thecutouts 23 and then performing welding for fixing. Finally, theprotective cover 9 is fitted. - It has thus been shown that the invention achieves the proposed aim and objects. The support, in addition to being particularly compact and lightweight, allows to achieve optimum centering and support of the bar; moreover, it ensures full compliance with customs regulations related to the transport of goods with trucks.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- A second embodiment of the support according to the invention is shown in Figures 7, 8 and 9.
- The second embodiment of the support is provided with a second
semitubular element 5, which has an upperlongitudinal extension 27 that is coupled to a lowerlongitudinal extension 28 of the base 2: theextensions - The upper
longitudinal extension 27 forms two substantially L-shaped tabs 29, which are suitable to engage inrespective slots 30 provided along the lowerlongitudinal extension 28, as shown in Figures 7 and 8. - All the details may be replaced with other technically equivalent elements.
- In practice, the materials used, as well as the shapes and dimensions, may be any according to requirements without thereby abandoning the scope of the protection of the appended claims.
