    [0002] Holding and guiding device for cutting a portion of ham by hand and for cutting into slices or fillets of other similar products.
    [0004] OBJECT OF THE INVENTION
    [0006] The object of the present invention is a novel device that firmly holds a portion of ham, previously boned, and provides a guide for the knife so that a non-expert can cut thin slices by hand. The invention can also be used for slicing other meat products, such as jerky.
    [0008] BACKGROUND OF THE INVENTION
    [0010] Currently, to cut an Iberian ham or shoulder by hand, a device generally known as a “ham holder” is normally used. that generally require the whole piece of ham arranged on it, forcing the non-expert user to handle a product that, due to its morphology, its characteristics (especially fatty) and its weight, entails difficulties to easily perform filleting. or sliced by hand (cut the ham by hand).
    [0012] There are several types of ham holders, although the most widespread ham holder consists of a structure normally made of wood that comprises a base at the ends of which a rear fixing element and a front fixing element are arranged. The rear fixing element is arranged on a post fixed to the base, and consists mainly of a ring crossed by screws to fix the end of the ham or shoulder where the hoof is. The front fixing element is directly connected to the base at the opposite end, and consists mainly of a screw for fixing the thick end of the ham or shoulder.
    [0014] There are other types of ham holders with relatively different configurations from those described, although they all have in common the fact that they only immobilize the ham or shoulder in a fixed position. In other words, current ham holders do not provide any help to the person who cuts beyond holding the ham or shoulder. Therefore, to make a proper cut, the person who cuts must control the thickness and dimensions of the each slice. As a consequence, to get a well-cut ham or shoulder, it is currently essential that the person who cuts is an expert in cutting hams or shoulders. In addition, the use of traditional ham holders, as they require a whole piece of ham destined for cutting, they are not designed to cut the ham by hand from the boneless product, that is, on the product previously divided into pieces or portions. Therefore, there are no effective devices that facilitate cutting a boneless ham by hand; that is, applying the cut by hand on portions or pieces of ham (previously boned) to obtain from such portions, thin slices of ham.
    [0016] In view of this situation, there is a need in this field for a ham holder that, in addition to effectively holding the ham or shoulder for cutting, facilitates cutting by hand into thin slices extracted from a portion or piece, previously boned, providing a help the person who cuts it.
    [0018] DESCRIPTION OF THE INVENTION
    [0020] The present invention solves the above problems thanks to a new ham holder design that not only holds a portion of the ham, but also provides guides for cutting each slice, so that the cutting of a ham or shoulder is made accessible to non-expert people. This device is suitable, above all, for holding pieces of boneless ham.
    [0022] The clamping and guiding device for cutting ham of the present invention basically comprises the following elements: a pair of vertical plates to hold the piece of ham; a means for tightening said plates; a horizontal platform to support the piece of ham; and a means of rotating a rod mechanically connected to the horizontal platform to allow its elevation. Each of these items is described in more detail below:
    [0024] a) Vertical plates
    [0025] It is a pair of parallel vertical plates connected in a sliding way through horizontal guides, so that they can move horizontally to get closer to or away from each other. As described in greater detail later in this document, this allows a piece of ham to be clamped between the two thanks to the compression force. Furthermore, said first and second plates comprise a straight and smooth upper edge to allow the guiding of a knife. Therefore, when the compressed piece of ham Between both plates it is arranged at a height such that a thin layer of ham protrudes above said upper edge, the user only has to horizontally move the knife guided by the upper edge of the plates themselves to cut a slice of ham.
    [0027] The plates can be configured with a rigid or semi-rigid structure, both flat and in the form of a grid, mesh or net.
    [0029] b) Clamping medium
    [0030] The clamping means is configured to push the second vertical plate against the first vertical plate to hold a piece of ham arranged between them. In this way, it is possible to compress ham pieces of different sizes.
    [0031] The clamping means can be configured in different ways, although according to a preferred embodiment of the present invention a spring-based mechanism is used having a first end attached to a lever arm that rotates about a horizontal axis attached to the first plate and a second end attached to the second plate. In this way, in a closed position of the clamping means where the lever arm has a closing orientation, the spring exerts a force tending to bring the first plate and the second plate closer together, compressing the piece of ham between them. Alternatively, in an opening position of the clamping means where the lever arm has an opening orientation, the spring does not exert any force on the first plate or the second plate, allowing their separation.
    [0032] In another preferred embodiment of the invention, the second end of the spring is fixed to the second plate through a rod threaded to said second plate that allows the spring to be tensioned and released. Therefore, when the aforementioned threaded rod is threaded or unscrewed, the extension distance of the spring changes and therefore the compression force that it applies on the first and second plates changes.
    [0034] c) Horizontal platform
    [0035] The horizontal platform is disposed vertically movably between the first plate and the second plate to provide lower support for the piece of ham so that it protrudes above the upper edge of the plates. Specifically, this horizontal platform is connected to a vertically sliding frame that is engaged with a threaded vertical rod.
    [0037] Preferably, the frame slides up and down along two guides vertical and is connected to the horizontal platform through horizontal arms that pass through vertical slots of the first vertical plate.
    [0039] d) Medium of rotation
    [0040] It is a means of rotating the vertical threaded rod, so that the rotation of said vertical threaded rod causes the elevation of the horizontal platform, and with it the elevation of the piece of ham as it is cut.
    [0041] In a preferred embodiment of the invention, the rod rotation means comprises an electrical mechanism that causes the automatic rotation of said threaded vertical rod when a button is actuated.
    [0042] In another preferred embodiment, the rod rotation means further comprises a manual mechanism comprising a lever attached to a ratchet-type mechanism. In this way, when the lever is actuated in a certain direction, it meshes with a ratchet wheel of the threaded vertical stem in such a way that it causes said threaded vertical stem to rotate in the direction that it causes the horizontal platform to rise, which thus rises. a little distance. The lever then returns to its original position when moving in the opposite direction, although in this case without engaging the ratchet wheel of the threaded vertical rod and, therefore, without causing the horizontal platform to rise or fall.
    [0044] In a particularly preferred embodiment of the invention, the device further comprises a distance limiting system that establishes a minimum approach distance between the first plate and the second plate. This makes it possible to adjust the device of the invention for pieces of ham of different thicknesses. More preferably, the distance limiting system comprises a rotatable arm provided with several parallel projections arranged at its free end that is fixed to the first plate and a rod projecting from the second plate. In this way, to adjust the distance between the first plate and the second plate, the stem is inserted into a gap between a certain pair of parallel projections on the arm.
    [0046] Thanks to this configuration, this device greatly facilitates the task of cutting a piece of ham into thin slices. The user only has to place the piece of ham resting on the bottom on the horizontal platform arranged between the first plate and the second plate. It then acts on the clamping means to bring the plates closer to each other and thereby compress the piece of ham between them, immobilizing it. Specifically, when using a clamping means of the type described above, the The user only has to rotate the lever arm from its opening orientation to its closing orientation, thus causing an increase in the distance between the two ends of the spring and, consequently, a force tending to move the plates against each other. When the piece of ham is already firmly held between the plates and resting on the platform, the user acts on the means of rotation, automatic or manual, of the threaded vertical stem to raise the horizontal platform until a thin layer of ham is protruding from the top. above the upper edge of the first and second plates. In this situation, the user can rest a knife on the upper edge of the plates and move it guided by it to cut a first slice of ham. Afterwards, the user acts again on the means of rotation, automatic or manual, of the threaded vertical stem to raise the horizontal platform again a small distance so that a new slice of ham protrudes above the edge of the plates, and then cuts the slice resting the knife on the upper edge of the plates. These steps are repeated indefinitely until the entire piece is sliced, with a thickness of the slicing or filleting to suit the user, who can determine with the electric or manual operation, the part of the ham that protrudes from the edge of the plates to be cut.
    [0048] The edge of the plates serve as a guide to the knife, allowing a homogeneous cut of the thickness of the ham slice. In this way, the device allows the ham to be cut by hand on a piece or portion of it, with full efficiency and without the need to require a whole piece of ham.
    [0050] Once completely sliced, or at any other time that is necessary, for example to change the orientation of the portion intended for cutting, the user can disengage the rotating means from the threaded stem to which the horizontal platform is connected. This enables the horizontal platform to be lowered or raised freely in a rapid manner to a desired position.

    [0063] PREFERRED EMBODIMENT OF THE INVENTION
    [0065] An example of device (1) according to the present invention is described below with reference to the attached figures.
    [0067] The device (1) comprises a first vertical plate (2a) and a second vertical plate (2b) that are parallel to each other. These plates (2a, 2b) have two sides flanges to prevent accidental exit of the piece of ham (100). The plates (2a, 2b) are joined through a pair of horizontal guides (3) essentially formed by a horizontal pin (31) connected to the first plate (2a) perpendicular to it and which is inserted in a cylindrical hole (32) connected to the second plate (2b) also perpendicular to it. In this way, the plates (2a, 2b) can move horizontally one perpendicular to the other so that they approach and move away.
    [0069] A clamping means (4) is configured to bring the plates (2a, 2b) closer to each other to clamp the piece of ham (100) between them. For this, the clamping means (4) is formed by a spring (41) having a first end (41a) and a second end (41b). The first end (41a) is fixed to a movable part of a lever arm (42) that rotates around a horizontal axis (43) of the first plate (2a), so that said lever arm (42) can alternate between an opening orientation and a closing orientation. The second end (41b) is fixed to a projection of the second plate (2b). When the lever arm (42) is in the open orientation, shown in Fig. 4a, the distance between the point to which the first end (41a) of the spring (41) is attached and the projection of the second plate (2b) to which the second end (41b) of the spring (41) is fixed is minimal. In this situation, the spring (41) is not pulled relative to its rest configuration, and therefore does not exert substantially any force on the plates (2a, 2b). When the lever arm (42) moves to the closing orientation, shown in Fig. 4a, an increase in the distance between the point to which the first end (41a) of the spring (41) is attached and the projection of the second plate (2b) to which The second end (41b) of the spring (41) is attached. As a consequence, the spring (41) is pulled and a contraction force is generated that tends to bring the plates (2a, 2b) closer to each other.
    [0071] The device (1) also comprises a horizontal platform (5) on which the piece of ham (100) rests. This platform (5) is connected to a frame (6) through three horizontal arms (62) that pass through respective vertical slots (63) made in the first vertical plate (2a). The frame (6), in turn, is vertically sliding along a pair of vertical guides (61) rigidly fixed to said first plate (2a). Furthermore, the frame (6) is engaged to a rotatable vertical threaded rod (7) fixed to the first plate (2a).
    [0073] Rotation of the threaded stem (7) in a controlled manner to thereby transmit a corresponding vertical displacement to the horizontal platform (5) is performed using one of an automatic rotation means (8a) and a manual rotation means (8b). The automatic rotation means (8a) may comprise an electric motor that drives a gear wheel that meshes with the vertical threaded rod (7). In this way, when the user presses a button in the middle (8a) of automatic rotation, the motor is activated for a certain number of turns that causes a small rotation of the stem (7) and, consequently, a certain distance of ascent of the platform (5) horizontal.
    [0075] The manual rotation means (8b) comprises a lever fixed to a ratchet mechanism, so that when the lever is operated in a certain direction, it meshes with a ratchet wheel of the threaded vertical stem (7) in such a way that it causes the rotation of said threaded vertical rod (7) in a direction that causes the horizontal platform (5) to rise, thus raising a small distance. The lever then returns to its original position when moving in the opposite direction, for example thanks to the action of a spring, although in this case without engaging the ratchet of the threaded vertical stem (7) and, therefore, without causing the horizontal platform (5) to rise or fall. Each complete stroke of the lever corresponds to a determined ascent distance of the horizontal platform (5).
    [0076] Thanks to this configuration, when the threaded rod (7) is rotated, either the automatic rotation means (8a) or the manual rotation means (8b), it causes a vertical displacement of the frame (6), moving the platform (5) vertically upwards to raise the piece of ham (100) resting on the platform (5) to the desired position. The vertical distance of horizontal platform travel (5) it will correspond to the thickness of the ham slice to be cut.
    [0077] The device (1) further comprises a system (10) for limiting the distance between the first plate (2a) and the second plate (2b). This system (10) allows adjusting the distance between the first plate (2a) and the second plate (2b) in order to adjust the device (1) to pieces of ham of different thicknesses. The distance limiting system (10) basically comprises a lever arm (10a) and a fixing rod (10c). The lever arm (10a) has one end hingedly fixed to the first plate (2a) and an opposite end that has parallel projections (10b), for example projections similar to the tines of a comb. The fixing rod (10c) is rigidly fixed to the second plate (2b). In this way, a certain gap distance between the first plate (2a) and the second plate (2b) can be set and then the lever arm (10a) rotated around the first end until the stem (10c fixing) is wedged between two adjacent parallel projections (10b). The fixing rod (10c) can be screwed to the second plate (2b), so that it can be pressed against said plate (2b) until firmly immobilizing the two adjacent parallel projections (10b) between which it is located.
    [0079] In another preferred embodiment of the device (1), the threaded vertical rotation means (8) can be replicated, in the same part of the device, forming two or more synchronized rotation means, yes, due to a greater dimension of the device (for example for cutting large pieces of ham), more than one means of rotation is required.
