[0001] DESCRIPTION
[0002] STACKABLE CABLE TRAY
[0003] OBJECT OF THE INVENTION
[0004] The purpose of this invention application is to register a stackable cable tray, which incorporates notable innovations and advantages over the techniques used to date.
[0005] More specifically, the invention proposes the development of a stackable cable tray which, due to its particular arrangement, allows successive stacking of a plurality of trays one on top of the other, under more advantageous stacking and storage conditions compared to the state of the art.
[0006] BACKGROUND OF THE INVENTION
[0007] In the current state of the art, cable trays in the form of a grid are known, consisting of a set of longitudinal rods joined together by transverse rods at certain distances.
[0008] In traditional cable trays, the crossbars are U-shaped, with two of their sides parallel and joined together by a base perpendicular to both.
[0009] While the shape is satisfactory for the function they perform, as the mechanical resistance of the tray is adequate, this is not the case in terms of the way they are grouped and stacked on top of each other for packaging, transport and / or storage.
[0010] This is because, when a plurality of trays are stacked successively on top of each other, a torque is generated on the two parallel sides that correspond to the U-shape of the transverse rods of the trays themselves, which causes deformation and bending on those sides, or even eventually their breakage, making their use difficult or even unfeasible.
[0011] A possible increase in the thickness of the rods or a greater number of them to avoid this problem, therefore implies an undesirable increase in resulting weight, a greater number of operations and difficulty in their manufacture and, ultimately, an increase in their prices and costs, thus reducing their competitiveness.
[0012] Accordingly, it is desirable to obtain a wire mesh cable tray that, while maintaining at least the mechanical characteristics of a conventional wire mesh tray, can at the same time be stacked, improving transportability characteristics and reducing final costs for the consumer, particularly when the movement takes place over long distances.
[0013] The present invention contributes to solving and resolving the present problem, since it allows successive stacking of a plurality of trays one on top of the other, under more advantageous stacking and storage conditions compared to the state of the art.
[0014] DESCRIPTION OF THE INVENTION
[0015] The present invention has been developed for the purpose of providing a stackable cable tray, comprising a plurality of longitudinal rods and a plurality of transverse rods, the longitudinal rods being arranged parallel to each other and the transverse rods also being arranged parallel to each other; wherein each transverse rod follows a U-shaped path and is contained in parallel planes separated by a certain distance; wherein the longitudinal rods follow a path perpendicular to the planes containing the transverse rods, and as a result, each longitudinal rod intersects with each of the other transverse rods;in which the transverse rods are also symmetrical with respect to a plane of symmetry that corresponds to their U-shape and in which said plane of symmetry is perpendicular to the plane that contains each transverse rod, resulting in the transverse rods having a central section that crosses their own plane of symmetry, and lateral sections separated from each other that start from the central section itself and are symmetrical with the same plane of symmetry of the transverse rods, and in which each lateral section is substantially perpendicular to the central section of the same transverse rod and follows a path substantially parallel with the same plane of symmetry, thus forming the central section and the lateral sections of the transverse rods the U-shape of the same transverse rods;in which each lateral section of each transverse rod, after its beginning from the central section, presents its path divided into an inner segment, an intermediate segment and an outer segment differentiated and arranged in that order from the beginning of the lateral section from the central section and maintaining the same lateral section its path substantially parallel to the plane of symmetry of the same transverse rod, and in which the inner segment is arranged closer to the plane of symmetry of the same transverse rod and the outer segment is arranged further away from the same plane of symmetry of the same transverse rod, and the intermediate segment is arranged at an intermediate distance from both in relation to the same plane of symmetry of the same transverse rod.;
[0016] Preferably, in the stackable cable tray, the inner segment results from a deviation in its path of the lateral section in relation to its parallelism with the plane of symmetry of the transverse rod and a return again to its initial path parallel with the same plane of symmetry, from which the inner segment of the same lateral section is closer to the plane of symmetry than the rest of the same lateral section.
[0017] Preferably, in the stackable cable tray, the outer segment of the side section results from a fold in the path of the same side section.
[0018] Preferably, in the stackable cable tray, the inner segment of the side section that is closest to the plane of symmetry of the same transverse rod is intersected by at least one longitudinal rod. Preferably, in the stackable cable tray, the inner segment of the side section that is closest to the plane of symmetry of the same transverse rod has a V shape.
[0019] Preferably, in the stackable cable tray, the vertex of the inner segment of the side section that corresponds to the V shape is intersected by at least one longitudinal rod.
[0020] Preferably, in the stackable cable tray, the fold of the side section is intersected by at least one longitudinal rod.
[0021] Preferably, in the stackable cable tray, the bend of the side section is intersected by at least one longitudinal rod precisely at a point where the bend deviation occurs.
[0022] Thanks to the present invention, a successive stacking of a plurality of trays one on top of the other is achieved, under more advantageous stacking and storage conditions compared to the state of the art.
[0023] Other features and advantages of the stackable cable tray will become apparent from the description of a preferred, but not exclusive, embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:
[0024] BRIEF DESCRIPTION OF THE DRAWINGS
[0025] Figures 1 and 2 are views from different perspectives of a preferred embodiment of the stackable cable tray of the present invention. Figures 3, 4, 5, and 6 are views from different perspectives of stacked examples of a preferred embodiment of the stackable cable tray of the present invention.
[0026] DESCRIPTION OF A PREFERRED EMBODIMENT As shown schematically in Figures 1 and 2 from different perspectives, the stackable cable tray of the present invention comprises a plurality of longitudinal rods, generally referred to as 1, and another plurality of transverse rods 2.
[0027] The longitudinal rods 1 are arranged parallel to each other, at the same time the other transverse rods 2 are also arranged parallel to each other.
[0028] As can also be seen in figures 1 and 2, each transverse rod 2 follows a U-shaped path, with each of these transverse rods 2 contained in parallel planes separated from each other by a certain distance, as can be deduced especially from the observation of figure 2.
[0029] As can also be deduced and appreciated from the observation of figures 1 and 2, the transverse rods 2 are symmetrical with respect to a plane of symmetry that corresponds to their U shape, and in that said plane of symmetry is perpendicular to the plane that contains each transverse rod 2.
[0030] The transverse rods 2 have a central section 21 that crosses its own plane of symmetry, and lateral sections 22 separated from each other that start from the central section 21 and are symmetrical with the same plane of symmetry as the transverse rod 2 itself.
[0031] Each lateral segment 22 is approximately perpendicular to the central segment 21 of the same transverse rod 2, and follows a path approximately parallel to the same plane of symmetry. As a result, the central segment 21 and the lateral segments 22 of the transverse rods 2 form the U-shape of the transverse rods 2, as can be seen and deduced from the observation of Figures 1 and 2. Furthermore, the longitudinal rods 1 follow a path perpendicular to and intersecting the planes containing the transverse rods 2, as can be deduced primarily from the observation of Figure 2. As a result, each longitudinal rod 1 intersects with each of the other transverse rods 2.
[0032] The stackable cable tray of the present invention incorporates some other features in its arrangement and configuration that allow it to provide remarkable performance and technical advantages in relation to the state of the art.
[0033] In relation to this, and as can be seen especially in figure 1, each lateral section 22 of each transverse rod 2, and after its start from the central section 21, has its path divided into an inner segment 221, an intermediate segment 222 and an outer segment 223 differentiated and arranged in that order from the start of the lateral section 22 from the central section 21, and the same lateral section 22 maintaining its path substantially parallel to the plane of symmetry of the same transverse rod 2.
[0034] The inner segment 221 is arranged in a position and distance closer to the plane of symmetry of the same transverse rod 2, and the outer segment 223 is in a position and distance further away from the same plane of symmetry of the same transverse rod 2. Between both, the intermediate segment 222 is arranged at an intermediate distance from both in relation to the same plane of symmetry of the same transverse rod 2.
[0035] In this preferred embodiment, as can also be seen particularly in Figure 1, the inner segment 221 results from a deviation in its path of the lateral section 22 in relation to its parallelism with the plane of symmetry of the transverse rod 2, and a return again to its initial path parallel with the same plane of symmetry, from which the inner segment 221 of the same lateral section 22 is closer to the plane of symmetry than the rest of the same lateral section 22. Also in this preferred embodiment, the inner segment 221 of the lateral section 22 that is closer to the plane of symmetry of the same transverse rod 2 is intersected in particular by a certain longitudinal rod 11.
[0036] In this preferred embodiment of the stackable cable tray of the present invention, the inner segment 221 of the side section 22 that is closest to the plane of symmetry of the same transverse rod 2 has a V shape, and the vertex of the inner segment 221 that corresponds to the V shape is intersected by the longitudinal rod 11.
[0037] Furthermore, in this preferred embodiment, and as can also be seen especially in Figure 1, the outer segment 223 of the side section 22 results from a fold 224 in the path of the same side section 22.
[0038] Said bend 224 of the lateral section 22 is intersected in particular by another certain longitudinal rod 12, precisely at a point where the deviation of bend 224 occurs.
[0039] These details explained allow the stackable cable tray of the proposed invention to offer remarkable performance and technical advantages in relation to the state of the art.
[0040] More specifically, the explained details of the stackable cable tray of the present invention allow for successive stacking of a plurality of trays one on top of the other, under more advantageous stacking and storage conditions compared to the state of the art.
[0041] In the normal use of cable trays known in the prior art, when carrying out a successive stacking of a plurality of trays one on top of the other, as can be seen in figures 3, 4, 5 and 6, the resulting added weight of one tray on top of the other generates a torque in the two parallel vertical sections that correspond to the U shape of the same trays, which entails a deformation and bending in these vertical sections, or even eventually their breakage, which makes their use difficult or even unfeasible.
[0042] Figures 3 and 4 show only two stackable cable trays of the invention stacked one on top of the other, in order to better appreciate the much more advantageous arrangement in their stacking.
[0043] Figure 5 shows five stackable cable trays of the invention stacked on top of each other, and Figure 6 shows a much larger number of stackable cable trays of the invention stacked on top of each other, which is in principle the most demanding and even common situation in the state of the art.
[0044] Specifically, and from detailed observation especially of figures 1 and 3, a technical effect can be seen resulting from an interaction between the inner segment 221 in the lateral section 22 and the other outer segment 223 in the same lateral section 22 of the same transverse rod 2 with the intermediate segment 222, as they are arranged at different distances in relation to the plane of symmetry of the same transverse rod 2, and at the same time the intermediate segment 222 of the same lateral section 22 is arranged in an intermediate position between both.
[0045] From the observation especially of figures 1 and 3, it can be deduced that when a stackable cable tray of the invention is in a superior position, arranged and supported by its weight on another identical one that is in a lower position, and is specifically supported on the longitudinal rod 11 that intersects with the inner segment 221, a torque is generated with respect to the intermediate segment 222 and directed towards the interior of the U-shape of the transverse rod 2 due to the weight of the stackable cable tray in the superior position and which exerts the support.
[0046] However, since the same upper stackable cable tray that provides support is also supported by its weight on the longitudinal rod 12, which intersects with the bend 224 generated by the outer segment 223 of the other identical stackable cable tray in the lower position, another torque is generated with respect to the same intermediate segment 222 due to the weight of the same stackable cable tray providing support, but directed in the opposite direction to the other torque explained above, since the outer segment 223 and the inner segment 221 are arranged on opposite sides with respect to the same intermediate segment 222. As a result, both torques will tend to cancel each other out.
[0047] Thanks to this, by carrying out a successive stacking of a plurality of trays one on top of the other, as shown in figures 5 and 6 even in large numbers, there is no longer any deformation or bending of the lateral sections 22 of the transverse rods 2 of the cable trays of the invention nor any risk of their eventual breakage, which represents an extraordinary advantage in the use and stacking and storage of the cable trays of the invention in relation to the state of the art.
[0048] The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the stackable cable tray of the invention, may be conveniently replaced by others that are technically equivalent and do not depart from the essence of the invention or the scope defined by the claims included below.
