Description

The invention relates to the technical sector of lifting apparatus and handling materials usable in the building for the presentation of plates of any material to constitute, for example, false ceilings.

For many years, the applicant has developed apparatus of this type intended to raise plasterboard other materials of great shape, size and weight since a height accessible to the user on the floor up to the ceilings that is donned to constitute said sub ceilings.

Devices of this kind have been designed and developed by the applicants who have, for example, the subject of patents FR 2 758 150, 2780428. These devices include a rolling base (1) with a mast (2) consisting of telescopic elements operated by a cable-pulley assembly muffled and operated by a winch (3). The upper end of the said mast is arranged to receive a plate (4) door material or door plate.

There is shown, Figure 1, a hoist of this type. According to In practice, the material carrier or plate holder is designed and designed to be presented in an oblique position for the reception of the panel then articulated to take a horizontal position in view of the presentation of the panel in the ceiling.

FIGS. 2 and 3 show the device enabling the articulation of the panel door. The upper end part of the mast thus receives a fixed horizontal support bar (5) on which articulates, with the aid of an operating lever (6), a stirrup (7) which receives transversely the support bar (7a) of the panel support plate. of the locking means (8-9) are provided for securing in position horizontal stirrup (7) and the support base (5).

The problem with this implementation lies in the fact that the lifting and handling equipment is not at all adapted to allow a presentation of the panels in a vertical position in order to arranging said panels to form partitions and the like. In in practice, said apparatuses are not designed to enable this function new and the implementation as exploited and illustrated in Figures 2 and 3 that there are problems with the stability of the device and safety.

The applicant's approach was therefore to think about an arrangement new door panel hinge device or door plate by to the mast and which can allow and ensure the new function mentioned above, and this in complete safety.

Another object sought after according to the invention was to design a device allowing the presentation of panels or plates to be laid in plans, vertical, horizontal, or oblique with placement on the device in oblique position for loading, and this in the context of a simple work and which requires for the operator only the execution of a only control maneuver.

These and other goals will emerge from the rest of the description.

According to a first characteristic of the invention, the device plate holder, panel holder, material for apparatus for lifting and handling, of the type comprising an upper end of the mast of the apparatus receiving a support profile of the frame of the plate holder, panel holder, said frame being mounted articulated with respect to said support profile, is remarkable in that said fixed support profile horizontal is offset from the mast portion and receives at the end a axis of articulation of the plate or panel support device, this comprising a support base with a flat upper wall serving support and attachment to the frame, and extended by two flanges parallel and perpendicular to the flat base, said flanges being arranged with two oblong, curvilinear lights, allowing the passage of a means of indexing and locking, and that the support base is likely to swing from one position to the horizontal while being locked to a vertical position, the corresponding oblique intermediate position loading the door panel or plate or laying on an inclined plane.

In order to make the object of the invention more concrete, it is described now in a nonlimiting manner illustrated in the figures of the drawings.

The device for articulating the support of plates or panels material is referenced as a whole by (10). It is likely to be fixed to articulation on an axis (11) relative to a fixed profile (12) horizontal forming spar and itself secured to the upper end mast (2) of the device. Said axis (11) is guided in a spacer (11a) (Figure 18) established in the profile (12), and receives a fixing nut (11b) and tightening. The device comprises a support base (13) having a flat upper wall (13a) of large width serving as a support position and fastening to the frame of the panel door and / or plate carrier (14) known as such and unaltered from the prior art. Said base support (13) has two parallel lateral flanges (13b-13c), perpendicular to the plane top wall (13a), and surrounding the profile fixed (12) above so as to form a kind of screed hinge. One of the flanges (13b) receives, in its upper part (13b1), with fixed position, an operating arm (14) controlling articulation and positioning of the device with respect to the mast portion (2) for the different positions of horizontality, verticality or oblique intermediate. The horizontal profile (12) is fixed in a way that most of its length is overflowing with respect to the mast (2) and wide offset to allow 90 ° pivoting of door panels or door plates, so that the base part of the device is not troublesome to the verticality of the door panels or door plates.

The device (10) according to the invention is arranged to receive security and locking means in position allowing indexation in position and avoiding any inappropriate maneuvering.

According to the invention, the device is established in an optimized version with flanges (13b - 13c) each having an oblong slot curvilinear (13b2 - 13c2) allowing passage and fixed positioning in the horizontal plane of an indexing and locking means (15) crossing the profile (12) on both sides to open on both flanges (13b - 13c) supra. The indexing and locking means (15) thus comprises an axis (15a) provided with a ring-shaped head (15b) gripping. The end (15c) of the axis is beveled by defining a bearing surface (15d) which comes into contact with the inner face facing the flange (13b). According to a particular arrangement, the axis (15a) is secured to a guide plate (16) shown in FIG. 14 by a pin (17), screw or the like, so that only the axial displacement of the axis by action on the ring is possible by driving the guide plate. This one thus has an opening (16a) for the passage of the axis (15a), two holes (16b - 16c) for introducing the connecting pin (17) and a U-slot (16d) allowing the introduction of a finger (18) disposed on the face transverse bearing profile (12) forming a spar. A way to call back Spring-type (19) is thus arranged on the axis (15a) between the plate of guiding and the inner face facing the flange (13b). We understand from when on the spring release action, the guide plate is maintained in contact and against the profile (12), the means (15) being not asked. In this implementation, the axis (15a), by its end (15c), opens into the oblong slot (13c2) formed opposite on the flange (13c). The bearing portion (15d) of the axis (15a) comes into contact with the face interior of said flange (13c). This position is established when the door panel or door plate is in oblique position of loading or transport.

For the extreme positions corresponding to the positions of use, either horizontally of the panel holder or plate holder, or vertically, the The applicant has sought an implementation guaranteeing the safety of handling and avoiding impromptu and inappropriate door tilting panel or door plate.

For this purpose, the two oblong lights (13b2 - 13c2) established on the flanges of the support base are made according to an angular sector differentiated on the one hand, and continuous or discontinuous on the other hand as it is hereinafter set out. The oblong light (13b2) established on the flange (13b) is locating on the receiver side of the locking means with the ring is established at an amplitude α 1 of 90 ° corresponding to the amplitude of tilting door panel or door plate and it is continuous. The oblong light (13c2) established on the other flange (13c) is established according to an angular sector less with an amplitude α 2 of the order of 65 ° discontinuously. In other words, light (13c2) is less important dimensionally in length as light (13b2) but with the same width. In addition, said light (13c2) is not uniform, it is discontinuous. She thus comprises an upper open part (13c3) independently forming housing of the end of the axis (15a) in the horizontal position of the door panel, then a full intermediate part (13c4) separating it from the rest of the main part (13c2), all in a curvilinear extension for adapt to tipping movements. Thus, the opening (13c3) is perfectly defined and is a means of blocking and locking in position of the axis (15a) and therefore of the panel door or plate holder. Alone the exercise of a force (F) on the ring of the means of indexing and lock (15) allows to release the pivoting of the door panel or door plate by disengaging the end of the axis (15a) of the receiving opening (13c3).

For the lower part corresponding to the verticality of the panel door, it is possible to integrate or not the security blocking function. In the hypothesis in which this function is established (situation not represented in drawings), the same way is provided by means of the safety of horizontality, an additional opening beyond the light curvilinear (13c2) with a similar implementation to the previous case but to the other end of the light.

If, on the other hand, it is not necessary to have this security additional for verticality, it is expected that said light (13c2) does not extend on the flange (13c) of the support base up to a level corresponding to the complete tilting of the panel door door plate. In this case, the indexing and locking means (15) comes, by its end, bearing on the inner face opposite said flask, thus being substantially clear, and this against the spring of aforementioned reminder.

Without departing from the scope of the invention, the means for indexing and latch (15) may have, as illustrated in FIG. 22, an axis (15a) of square section while the profile (12) is arranged with an opening of corresponding section for the introduction of the axis. Two washers (21 - 22) are arranged on the axis (15a), one (21) being integral with the axis and bearing against the profile, and the other (22) being against the head, the return spring (19) of the type previously described lying between said washers and on the axis. This implementation ensures a construction simplified.

Thus, the device of the invention is extremely practical to put implemented and offers, by a simple manual action on the indexing means and lock (15), all possibilities of presenting the apparatus for the position sought verticality, horizontality or intermediate for the loading.

Note that, according to a known arrangement, the profile (12) can have an overflowing vertical finger (20) engaging in an opening (13f) formed on the upper planar face of the support base.

The advantages are apparent from the invention. We highlight the simplicity of the device, the clever implementation of two lights oblong with different characteristics.
