DESCRIPTION

Trolley that can be transformed into a workshop table and ladder.

Object of the invention

The present invention, as expressed in the wording of this specification, refers to a trolley that can be transformed into a workshop table and ladder, which has notable relevant and advantageous characteristics compared to those that currently exist and that can be considered of its type.

Background of the invention

The folding structure of a trolley for transporting work tools is known, described in utility model No. 200302378, which also materializes a table in the unfolded position of its racks, and where the operator can have the tools he needs grouped and at hand to perform a certain job.

Utility model n ° 200402908 also revealed a work table that could be converted into a trolley, thus offering a double utility since, in addition to constituting a robust table in the unfolded position, when folded it can be used as a transport trolley as it has an orthogonal plate directed to the outside on the wheel carrier frame, supporting the goods to be transported on this plate.

Description of the invention

Well, the trolley that can be transformed into a workshop table and ladder, object of the present invention, in addition to presenting a robust and reliable structure both in the folding and unfolding position of its frames, to fulfill its function as a table and as a transport trolley , It can also be used as a ladder since one of its support frames in the table position has the corresponding steps and, in addition, a pair of handles is included in the upper part that facilitate the ascent by becoming a safety means.

The structure of its frames, as well as the way in which they are folded to be attached to the tabletop occupying a minimum space and having effective fastening means in this folded position, also represent a significant advantage with respect to the way in which that the folding and unfolding is carried out in the objects of the aforementioned utility models, thus assuming an improvement of the same.

It is made up of a board or surface that can be used as a table, rectangular in shape and at the ends of which two frames articulate as support elements when used as a table. One of these frames carries two wheels and the other is made up of two generally vertical stringers and a series of cross members based on rungs when used as a ladder. The lower part of both frames is related to a horizontal frame that stably fixes the table position, this horizontal frame being foldable with respect to the lower part of the wheel frame, having a “U” shape and the articulation axis being the ends of the wheels. its branches. The web or connecting section of these branches has anchoring means complementary to those existing in the ladder frame to obtain the assembly position of the table.

The wheel frame has on its outer face a davit to support a tool box and on the inner part a wide support plate for the goods to be transported in the folded or trolley position, since in this position said plate is directed outwards, orthogonal to the deck.

The ladder frame has at the ends of its beams some bent extensions whose ends are related by means of an axis which in turn passes through a pair of handles for the operator to grasp in the trolley position.

The beams of both articulated frames incorporate, in proximity to the articulation points with the deck, two stops that contribute to stabilizing the assembly in the unfolded position.

In the folded position, the three articulated frames are located on the same plane attached to the tabletop.

The deck is protected by two lateral profiles on its longitudinal sides, having orthogonal tabs on its respective lower face, for articulated anchoring of the attached frames.

The general structure is welded and painted and there is a good fit in the articulation of the frames.

In the folded position of the three articulated frames, a blockage of the assembly is achieved as there are spring-assisted closing triggers.

We can also indicate that the trolley that can be transformed into a workshop table and ladder, has, in addition to the davit for a tool box, other complementary means for better holding and transporting certain pieces such as rolls or hoses, for which it can include a grill in the frame and hooks for anchoring and transporting these elements.

To facilitate the understanding of the characteristics of the invention and forming an integral part of this specification, some sheets of plans are attached in whose figures, with an illustrative and non-limiting nature, the following has been represented:

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how the trolley that can be transformed into a workshop table and ladder, which the invention proposes, includes a board (1) with the two longitudinal profiles (2) that protect its edges and are shaped like a "U", also having an orthogonal fin (3) on the back or underside of the board (1). At one of the even ends of the fins (3) articulate the stringers (4) of the ladder frame (5), which has crossbars (6).

This frame (5) has its free end provided with angled extensions (7) anchored to its beams (4) to which the handles (8) for handling the truck are made integral, as can be seen more clearly in figure 2. In the folded position this frame (5) remains inside the fins (3) of the longitudinal protection profiles (2) of the deck (1).

At the other end of the profiles (2) articulates the frame of wheels (9) defined by the beams (10)

ES 1 060 465 U arranged outside the fins (3). To the free ends of the beams (10) is fixed the support (11) for anchoring the wheels (12) for use as a trolley. This support (11) includes the extension (13) orthogonal to the plane of this frame (9) of wheels, to support the goods to be transported, as well as the lugs (14) between which the mounting shaft (15) is held. of the wheels.

Now making special reference to figure 3 where the deployed position is shown in its application as a work table, we can see that the visible face of the board (1) that was the support of the merchandise to be transported as a forklift (together with the extension orthogonal (13)), it remains as a useful surface in the position of the work table with the tabletop (1) horizontal, once the frames (5) and (9) referred to above have been deployed.

The assembly in this table position is achieved by the frame (16) in "U" which is articulated by the end of its branches (17) to the lower end of the frame (9) of wheels, as seen in the figure

3.

The ladder frame (5) includes, in proximity to the articulation point of its beams (4) with the board (1), two handles (18) for use as a ladder, the end portion (19) of these also acting as means of stop against the board (1), limiting the maximum opening.

For its part, the frame (9) of wheels is also limited in its opening when the front surface (20) of the widened ends of its beams (10) also abut against the board (1).

Reference (21) designates the studs fixed to the board (1) to keep the first (5) and second (9) frames in the folded or folded position, as the spring-assisted end triggers lock in them.

Reference (22) designates the davit of the wheel frame (9), to support a toolbox or other accessories.
