Description

The present invention relates to the technical field of devices for loading lifting materials, which can be used in the construction industry for lifting boards made of any materials, in order to build suspended ceilings or install them at an angle to the roof and partitions.

Devices of this type have been developed that are designed to hold rectangular sheets of drywall, or plaster panels, or boards and panels made of other materials having large dimensions, for example, lengths of 3 meters or more, and therefore very heavy. These boards, thanks to devices of the aforementioned type, are lifted upward in a horizontal position due to the winch mechanism and by tilting so that they can be attached to the ceiling to be covered. The devices were developed on the basis of Patents FR 2758150, 2780428, and 2862682. In particular, in FIGS. 1, 2 and 3, the latter patent provides for the use of a fixed support compartment that is offset from the mast part and at its ends includes means for pivoting a device that holds a board or panel, the device including a support base configured to tilt from a horizontal locked position to a vertical one, which corresponds to loading the panel or board holder or installing them on an inclined surface.

The devices disclosed in the above patents are widely used with significant commercial success.

In FIG. 1-3 shows a device for pivoting the holder of a board or panel, which is capable of tilting relative to a stationary horizontal compartment (1) attached to the upper end of the mast (2) of the device. This device comprises a support base (3) having a very wide flat upper wall with a U-shaped bracket (4), which is used to support and attach to the frame (5) the board holder and / or panel holder. The control lever (6) is attached to the support base and adjusts the inclination and location of the device relative to the mast. Means for blocking by means of the control handle (7) and the fixing bolt (8) block and unlock the swing of the support base. Additionally, the support base has a hole (3a) for the finger (9) for positioning and locking the board or panel in its limit position.

However, the manufacture and assembly of such an implementation are expensive. The device of the mounting bolt, in the classic configuration of the lock, must be fitted, and this requires additional costs and additional interventions and work.

The objective of the present invention is to provide such a device for loading and lifting materials for boards or panels, the manufacture of which is more efficient, especially due to the main part of the device, namely the one that includes a device for articulating turning and lifting the panels without affecting the satisfactory the work of the device.

The problem of optimization and manufacturing of a device for loading and lifting materials, such that it has other functions that meet the requirements during the operation of the device in place, was also solved.

In fact, it was observed that the supporting frame of the board was immersed on the device for orienting the boards and panels by trial and error. The supporting frame of the board is suspended and guided on a U-shaped portion of the bracket of the upper surface of the articulated support base. To achieve this and installing the support frame of the board / panel, the operator often presses the control lever of the device with his shoulder so that he can see the location of the frame. Therefore, such pressure is applied across, and the operator has both hands free to ensure proper positioning. Therefore, such a process and control method are not very practical.

Therefore, the attempt to optimize the device proposed in the present invention included the solution of this separate problem in order to further simplify the intervention and operation of the operator. The priority in this invention was the manufacture of devices to ensure the simplest possible use of the device in place.

These and other tasks will become apparent from the following description.

The first object of the invention is a support device for the holder of boards and panels for devices for loading and lifting materials of the type containing the mast, at the end of which are equipped with means for support, which with the possibility of articulation can accommodate the supporting frame of the board, which is characterized in that it contains U-shaped rack, between the side sections of which are placed two hinge pins, the first pin providing pivoting of the support base, on which the support frame for the board or Aneli, and on the second hairpin there is a dog that sways freely due to the distribution of its mass, while the dog has a head that forms a hook for connecting and placing around the hairpin, which forms a finger, which protrudes from the support base, a straight rear surface that forms the limit emphasis, and a control lever, the end of which has the shape of an unbalanced mass.

In order to make the present invention easier to understand, the following description is given, by way of example only, with reference to the accompanying drawings.

As shown in FIG. 4, a device for loading and lifting materials for boards or panels intended for mounting on ceilings or walls is generally indicated by (A), and its base is equipped with any suitable method, rolling means (R), gripping means (B) and cable control for deployment, telescopic or not, mast components (2). The extreme upper part of the mast receives the device (D) of the invention, on which the support panel (5) of the board or panel holder rests, and which is attached to it either removably or permanently by welding. The mast may also provide the ability to attach a receiver (P) to accommodate a portable power tool or other equipment needed by the operator.

The board or panel holder device according to the invention can be used with devices for loading and lifting materials of any structure, and the embodiment shown in FIG. 4, therefore, is made only to facilitate understanding of the device.

In FIG. 5-15, the board holder device (D) was constructed and constructed to perform various functions, which will be explained below. In more detail, the device comprises, starting from the end of the mast, a U-shaped post (10) attached to the mast at its bottom (10a) by welding or by another method, and located horizontally with its open surface up. Between its parallel, vertical side sections (10b-10c) are two hinged studs (11-12), one of which (11) is located in the tail, and the other (12) in front of the rack. The stud (11), traditionally, makes it possible to swivel the support base (13) onto which the support frame (5) of the board or panel holder is directly or indirectly mounted. In the embodiment of FIG. 5-13, the support base has such a structure that its upper surface is in the form of a bracket (4), forming a separately installed slider, and fixed in any suitable way, and limits the groove (4a), allowing the support base to slide (5), the lower profile which has a matching design. Depending on the circumstances, the bracket can accommodate the supporting base (5) in two positions 90 ° apart, one position makes the so-called horizontal installation on the ceilings possible, and the other position allows the so-called inclined installation under the roof slope. In FIG. 14, 15, a support base is shown which accommodates a support frame permanently attached to it by welding or an equivalent method. The supporting base (13), in accordance with the invention, made in the form of a U-shaped section with side sections (13a-13b), is mounted on a stud (11) and placed in the inner space between the side sections (10b-10c) of the rack (10) . The above-mentioned base also accommodates a fixed stud (14), which protrudes on one side and is installed between the side sections (13a-13b), and the protruding part (14a) serves as a finger. One end (15a) of the L-shaped control handle (15) is attached to the support base by welding, or an equivalent method, taking into account that the part to be covered (15b) is located in a plane that is at right angles and opposite to the operator. The front of the rack (10) accommodates a stud (12), on which a dog (16) is installed with the possibility of articulation, having a significantly different profile. This dog is mounted on a hairpin (12) with a slight offset from the center to ensure imbalance so that it seeks to make a swinging motion. At the end, which is inside the strut (10), the aforementioned dog has a head (16a) having the shape of a hook (16b), which faces its other end (16c). The rear surface (16d) of the head is straight and is located in a plane that is perpendicular to the horizontal bottom of the rack and the horizontal bottom surface of the support base when the latter is reduced. The head (16a) of the dog is high enough to extend from the horizontal plane of the support base when the dog engages with the finger (14a) to provide a limit contact surface for the frame that supports the panels or boards to be installed, regardless of the orientation of the support base (5 ) in the groove (4a) of the bracket (4). The head (16) has, in front of its rear surface, an upper part (16e) with a curved shape that makes up the abutment surface under the circumstances described below. The dog has an opening (16f) for mounting it on a stud (12). The other end of this dog, in front of the pivot pin, has the shape of an unbalanced weight control lever (16g), which, when not activated, forces the dog to lean forward due to its mass distribution, thereby acting as a counterweight. The bottom surface of the strut has a through groove (10d), which provides the possibility of articulated rotation of the lever, rocking and passing through the bottom surface.

The various functions of the device are described below. The boards or panels can be immersed on the support frame in complete safety, either after hinging the support base so that it occupies a horizontal position and locks in this position, or by pressure through the pin (14a) on the shaped head of the dog. In the first case, due to the weight of the support frame, the dog turns back in order to engage with the finger (14a). The dog returns to a locked position due to its imbalance.

Panels or boards can be installed very simply and quickly by double exposure from the operator: firstly, by unlocking the dog by raising it by the gripping part, and secondly, by orienting the support arm connected to the support base. Orientation of the device provides the possibility of completely safe location of boards or panels. Unlike the prior art, there is no need for the operator to reposition the support arm by applying pressure on it with the shoulder to ensure that the support frame for the board or panel is correctly positioned. The dog provides, by means of its various positions, the blocking of the support base, the irrevocable limit of the stop of the support frame of the board and the support, if applicable, for the support base in its inclined position in another part of the dog acting as a support, or provides the possibility of inclined loading.

The solution proposed in the present invention is simple and helps to achieve a significant reduction in production and assembly costs. The operation of the device is simplified and there is no longer any risk of a bolt sticking, which could happen in previous devices.

The solution in accordance with the invention is practical, regardless of the way in which the support frame is positioned and attached.
