Description

 STACKABLE AND DISARMABLE METAL STRUCTURE TO BE USED WITH PARIHUELAS OR WOOD PALLETS.

I. DESCRIPTIVE MEMORY

Secipr of the Technique: The present invention relates to a stackable and disassembly or detachable metal structure that together with wooden parihuelas serve to stack or transport cargo containing fragile materials; in other words to move heavy loads, stackable on three levels in warehouse and two levels on trucks.

BACKGROUND OF THE INVENTION: Storage using pallets or pallets was carried out in the ground, at a single level. Also known are pallets or parihuelas and fixed shelves. The main problem with these single-level parihuelas is at the time of transport, because a parihuela would only carry a certain load, being unable to stack another parihuela one on top of another due to the deterioration of the merchandise, so the problem that arises is that large storage areas are occupied at a single level. The invention seeks to have a greater volume of stored products, since three levels of storage would be used. Furthermore, said shelves can be moved from one place to another.

Description of the invention: By means of the structure of the invention it is proposed to transfer cargo taking advantage of the space during its storage in warehouses and in vehicles. Thus, the following description will be made to detail the characteristics of the stackable and removable metal structure that is made up of three levels with the following elements: α Four tubular columns of iron or stand, which will serve as a framework for the stackable and dismantlable metal structure. α Two square section steel tubes or quadrangular tubes, which are placed two at each level of the structure, such that each tube has a "U" groove near its ends, at the height where they join with the columns Tubular by welding. α Two steel crossbars formed by an inverted "U" shaped gutter that also have an inverted "U" shaped recess near their ends, using two crossbars at each level of the structure, such that said crossbars fit into the "U" groove of the quadrangular tubes. These crossbars have a bolt on both sides of each gutter. α Two rectangular fixing braces of platen or tempered braces, so that each of them form an "X", joining by means of a rivet in the middle part of said braces to make them foldable, at each level of the structure. α Two clamps of a first type, each clamp formed by five steel plates, three of them are formed by a single piece to which two 90 ° folds or folds have been made to form a "U" and the other two plates are joined at the ends of the piece in the form of "U", by hinges, where one of the plates have a stop to secure the clamp and the other has a square hook in the form of a buckle that serves as a lever when closing The clamp. α Two clamps of a second type, which have the same technical characteristics described for the clamps of the first type, but also have each welded, a steel plate or arm in the form of the "L" that serves to be attached to the end of the wooden pallet, such that two tubes are welded in said arm into which the pins of the braces are introduced, α Two inverted "T" shaped tubular supports. .. α Four hollow metal cylindrical rings. α Four support tubes in the four corners of the structure, where each of them is welded, one of the ends near the upper end of the tubular iron column and the other end at the end of the square section tube (quadrangular tubes) , forming a hollow triangle when the support tube is welded, which will serve to better secure and support the structure. α Rectangular plates that have a hole in one of their ends to secure the braces that are welded at the ends of the square section steel tubes, which serve as a guide when stacking the next structure or rack. α Square plates of 10 cm side, which are placed in the lower part of each tubular column of iron or stand as a support; and also for a better stacking of the structures one on another. α Two upper pins and two lower pins, with a joint to support and secure the temper braces, so that they do not release or escape. The upper pins fit on the rectangular plates, and the lower pins on the clamps. α 90 ° angle sections. welded in the union of the steel tubes of square section and the crossbars, to facilitate that the next metal structure or rack, which goes on the second or third level can be deposited more easily and safely.

The metal structure is shaped as follows:

Four tubular iron columns that are welded to two square or quadrangular section tubes. adapted to Ia. length (length) of the pallet, such that said tubes quadrangular have a "U" shaped groove at the height where they join with the four tubular columns, so that the two crossbars formed by an inverted "U" shaped gutter are fixed to the square section tubes, and also they have at their ends a recess in the form of an "U" inverted to be able to be fixed to the tubes of square section (2) in the groove in the form of "U", avoiding lateral displacement, and at the same time that will help to support the parihuela and the four tubular columns that will go on the second or third level of the metal structure; two rectangular platen fastening braces which are placed at the back of each level of the metal structure, forming an "X" by means of a rivet in the middle part of said braces to make them foldable, said braces having a circular hole in each upper end, which are welded to the upper pins placed in the hole of the rectangular plates of the square section tubes, while the lower ends of the braces have welded lower pins (smooth iron rod V≥ inch) to enter the tubes that are welded to the "L" shaped steel arm of the second type clamps. The two clamps of a first type are welded to the front tubular supports, while the two clamps of the second type are welded to the rear tubular supports to join with the holes of the lower ends of the braces by pins; such that at each level two clamps of each type are placed, which serve to hold the wooden parihuelas of each level with the metal structure. Where the clamps of the first type are formed by five steel plates, three of them are formed in one piece to which two 90 ° folds or folds have been made to form a "U" and the other two plates are joined to the ends of the "U" shaped piece by hinges, where one of the plates has a stop to secure the clamp and. The other has a square hook in the form of a buckle that serves as. lever when closing the clamp; and the clamps of the second type which also have each one welded, an iron or "L" shaped steel arm that serves to be attached or attached to the end of the wooden pallet and the braces, such that two tubes are welded in these arms in which the pins of the braces are introduced. An inverted "T" shaped tubular support, such that the end of the vertical pipe of the "T" is welded to the square tube and the ends of the horizontal tube of the inverted "T" are welded to a hollow cylindrical ring through which the Tubular columns and thus remain attached to the columns. The purpose of these rings is to avoid displacement due to possible overweight and also so that the support is not so rigid making a total of four cylindrical rings for each level.

Likewise, a support tube (11) is welded between the upper end of the tubular iron columns and the ends of the square section tubes (quadrangular tubes), forming a hollow triangle when the support tube is welded.

It should also be noted that at the base of the four tubular iron columns, the 10cm square plates are welded, so that they give stability to the metal structure.

α Finally, the 90 ° angle sections are welded, in the union of the square section steel tubes and the crossbars, to facilitate that the next metal structure or rack, which goes on the second or third level can be deposited more easily and safely.

STACKING CASE ON A SECOND OR THIRD LEVEL The second level joins the first level, placing or stacking the following four tubular columns with their respective clamps on the two square or quadrangular section tubes corresponding to the first level, and at the same time the third level is stacked on the second level by placing the following four tubular columns on the square section tubes of the second level.

Both the clamps of a first type, and the clamps of the second type have the function of fixing and securing the wooden pallets or parihuelas of each level with the metal structure, since said clamps are introduced and wrapped in the empty spaces that form the wooden plates of the parihuelas, then close them and ensure that they are fixed in the metal structure. According to the storage needs, the detachable metal structure can be stacked in two or three levels.

90 ° angle sections, welded in the union of the square section steel tubes and the crossbars, to facilitate that the next metal structure or rack, which goes on the second or third level can be deposited more easily and safely .

DETAILED EXHIBITION OF THE BEST WAY TO CARRY OUT THE PRACTICE Below is the best way to put the invention into practice:

Metal structure formed by four tubular iron columns (5) that in its upper part are welded to two tubes of square or quadrangular section (3) adapted to the length (length) of the pallet, such that said quadrahgular tubes have a shaped recess of "U" at the height where the four tubular columns meet; so that the two crossbars formed by an inverted "U" shaped gutter (2), which also have an inverted "U" shaped recess near their ends to be able to be fixed to the square section tubes in the shaped groove of "U-, to avoid lateral displacements, and. less time to help support the parihuela and the four tubular columns that will go on the second or third level of the metal structure; two rectangular plate tie-down braces (4) which are placed at the back of each level of the metal structure, forming an "X" by means of a rivet (26) in the middle part of said braces to make them foldable. Said braces have a circular hole in their upper ends, to be connected by means of pins to the tubes of square section; while the lower ends have welded 14 "(inch) flat iron rod pins to introduce them to the tubes that are welded to the" L "shaped steel arm. Two clamps of a first type that are welded to the front tubular brackets, while the second type clamps are welded to the rear tubular brackets to join with the holes of the lower ends of the rectangular braces by means of pins, such that on each level two clamps of each type are placed, which they are fixed to the hoists to hold them in. Two tubular supports in the form of an inverted "T" (24), such that the ends of the vertical tubes of the inverted "T" are welded to the quadrangular tube (3) and the other ends of the tube horizontal of the inverted "T" are welded to hollow cylindrical rings (25) through which the tubular columns (5) pass and thus remain attached to the columns. The purpose of these rings is to ev Move the displacements by a possible overweight and also so that the support is not so rigid making a total of four cylindrical rings for each level.

In addition, a support tube (11) is welded, between the upper end of the tubular iron columns and the ends of the square section tubes (quadrangular tubes), forming a hollow triangle when the support tube is welded.

Also, the 90 ° angle sections are welded at the junction of the square section steel tubes and the crossbars, to facilitate that. Ia Next metal structure or rack, which goes on the second or third level can be deposited more easily and safely. In this way, the second level is joined, stacking the following four tubular columns with their respective clamps on the angle sections and the quadrangular tubes corresponding to the first level, and in turn the third level is stacked on the second level by placing the following four columns of the third level on the square section tubes of the second level.

SECOND PREFERRED EMBODIMENT A second alternative of construction of the structure, is that instead of welding the inverted "T" shaped tubular supports (24), a horizontal tube is welded, which is also attached to the hollow cylindrical rings where pass the tubular columns or parantes and thus remain attached to the columns. In this case, rings are welded in the upper and lower part of the cylindrical rings and the stop; so that there is mobility, as seen in the isometric view of the second embodiment.

TECHNICAL ADVANTAGES: The advantages that derive from the stackable and removable metal structure is that fragile cargo can be stacked on three levels in warehouses or on two levels in trucks or cargo transport vehicles, maximizing space both at the time of storage how to transport such cargo, also saving transportation and storage costs. In this way it is possible to triple the storage space in the factories, because the parihuelas can be stacked up to three levels; and the space will be doubled when the load is placed in a means of transport. Likewise, it has the advantage of the structure that the fragile load will not be damaged because they are protected within the structure, and the weight of the load placed in the structures of the second or third level does not affect the load contained. in the structure. of the first level; the. c.uaLse. achieved due to. The configuration of the metal structure and its corresponding elements that give it the support and articulation necessary for its assembly in a fairly practical way by a single person or operator, due to the ease of assembly of its parts. Likewise, the advantages derived due to the configuration of the clamps and the braces at each level of the structure making the structure quite manageable on the whole when transporting them to the truck that moves the merchandise.

Possibilities of application:

The stackable and removable metal structure can be used in factories that work with products packed in cardboard boxes, in which the stacking of products in warehouses and at the time of transport in cargo vehicles is necessary.

The structure of the invention is not limited to the dimensions shown, and can be adapted to the needs of the load to be stored.
