Abstract

A device is designed for fixing elements (105) on a body (C) by block means (112). The elements (105) for the body are fixed in frangible way to a respective frame (107) so making with them a first set (101, 102, 103) of elements. The block means (112) for elements (105) of the first set of elements (101) are mutually joined in a frangible way forming a second set (111) of block means (112) and having respective seats (113) which, in a fixing condition of elements (105) to body (C), they are designed to house and block corresponding link means (108) of the respective elements (105) where said link means (108) pass through body thickness (C). Said device (1) comprises at least a separating and housing means (3) designed, in cooperation with a shear means (5) operated towards and away from the separation and housing means (3), to separate the elements (105) of first set of elements (101) from respective frame (107) and housing said elements (105), with the respective link means (108) facing outwards, in the separation and housing means (3). The device (1) further comprises a mesh means (7) intended to house the block means (112) of second assembly (111) and operated in approaching and moving away from the separation and housing means (3) to cause the passage of link means (108) through the body (C) and to make the engagement and locking of said link means (108) in the respective seats (113) of block means (112).

Description

DESCRIPTION OF THE INVENTION

The present invention relates to the technical field concerning the mounting identifying and/or decorative elements, for example a string or matrix of graphic elements such as characters, symbols, logos, decorations, etc., on a two-dimensional prevalent development body such as a fabric, leather, hide, paper derivatives, plastic and synthetic materials, and other products for the production of clothing, clothing accessories and other goods.
It is common to apply elements, for example characters and/or logo of a brand or décor, on a clothing article, belt, bag or other accessory or leather goods in fabric, non-woven fabric, leather or hide and their substitutes, plastic sheets, cardboard or metal and the like.
These sets of graphic elements, generally applied as string or matrix, are usually applied by means of adhesives, sewing or by riveting or punching.
These methods of fixing the elements take a long time and are subject to mistakes in the composition of the elements and their positioning, with the risk of applying incorrect or irregularly arranged text.
To facilitate its application, the graphic elements can be made, arranged in their definitive configuration, in a single body with a frame joining them through frangible bridges. The element faces fit for matching with the body can each have one or more protruding nails or feet designed to pass through the body to engage into corresponding seats formed in locking means corresponding to the elements and mutually connected by frangible joints, for example, also as frangible bridges. When the feet pass through the body and are inserted into the corresponding seats of the locking means, they are riveted so as to definitively fix the assembly.
After application, each element is separated from other elements and from disposable frame and at the same time the locking means are mutually disconnected by breaking the bridges or fracturing links.
The known presses allow the application of these elements by means of opposed supports for the elements joined by frames and by block means.
The body is placed between the supports approached by the press by nailing of the elements to the support means between which fabric or other body is interposed.
Such known presses allow to speed up the work but have the disadvantage of a limited application flexibility, for example they do not allow the application of elements made of different materials or colors or finishes.
Another disadvantage of such known presses is the complexity of the operations that the operator must perform in order to correctly position the elements and the corresponding block means.
Another disadvantage of the known presses is the risk of deformation of the graphic elements due to their incorrect detachment.
An object of the present invention is to propose a device for fixing elements on a body that allows to apply on this body non-homogeneous elements or of different nature, color and/or materials.
A further object of the present invention is to propose a device which allows to fix in an efficient manner, even in case of small or medium productions, both homogeneous elements, or carried out with the same material and having the same color and surface treatment, and non-homogeneous elements.
A further object of the present invention is to propose a device fit for preventing damage to elements and to separate them perfectly from the respective frame.

With reference to Figures 1-11, numerals 101, 102, 103 indicate a first set constituted, in the case of set 101 of Figures 1-3, by a set or, in the case of first sets 102, 103 of Figures 7-10, by complementary subsets of elements 105.
Each element 105 of the element set to be applied to a body C is provided with link means 108, for example comprising one or more fixing pins.
Each element 105 of the first set 101, 102, 103 is joined to a respective frame 107 by means of bridges 110, for example with a cross section of the fastening end of the element which is very small and in any case smaller than the other sections of the bridge.
Numeral 111 indicates a second set consisting of block means 112, one for each of the elements 105 to be applied to frame 107. These block means 112 are joined by frangible links. Each of said block means 112 is provided with one or more seats 113 for the pin or the pins for fixing the link means 108 of the corresponding element 105.
The elements 105 of the first set 101, 102, 103 and the block means 112 of the second set can be made of one or more materials including metal, metal alloys, plastics, resin, wood and generally organic and inorganic materials.
The elements 105 intended to be fixed to a body C, for example those of Figures 1-3, may be of the same material and/or of the same color or finish, or, with particular reference to Figures 7-17, may be of different materials, colors and finishes; for example, the elements 105 of Figure 8 may be made of silver-plated metal and the elements 105 of Figure 9 may be made of gilded metal, thus composing a decoration to be applied to the body with silvered and gold-plated elements. In another example, the elements 105 of Figure 8 may be made of red plastic and the elements 105 of Figure 9 may be made of plastic or other black material by making a decoration applied to black and red body.
The portion of elements 105 being visible after application to body is shown as boss, for easy representation, but may be of any shape, for example of alphabetic and/or numerical characters, of geometric elements, objects or animals or any symbols, logos and decorations.
The invention allows to place elements 105 in a pre-established manner, for example to compose a writing or a mark, or variable manner using various and different types of first set 102, 103 containing subsets of elements 105 to be applied to body. The illustrations and descriptions of the first set 101, 102, 103 and the second set 111 provided herein are purely exemplary and cannot exclude different configurations of such sets and/or of elements and of block means 112.
The body C may consist of material used for bags, handbags or suitcases, for example leather, natural or synthetic leather or their substitutes, fabrics, non-woven fabrics, Alcantara®, or of material for clothing, covering, upholstery. It is also expected that the body may also consist of plastic, metal, cardboard, wood or other resistant materials; in this case, the application of elements 105 will require the previous adjusted drilling of material for the passage of link means 108 of elements 105.
With reference to Figures 12-37, numeral 1 indicates the device for fixing elements on a body, object of the present invention, which comprises at least a separation and housing means 3 intended in cooperation with a shear means 5, operated approaching and moving away from the separation means and housing 3, separating elements 105 of first set 101 of elements from the respective frame 107 and housing said elements 105 with the respective link means 108 facing away from the separation and housing means 3.
The device 1 also comprises a mesh means 7 intended to house the block means 112 of the second set 111 and actuated towards and away from the separation and housing means 3 for realizing the passage of link means 108 through the body C and the engagement and locking of said link means 108 in the respective seats 113 of the block means 112.
The separation and housing means 3 comprises a base means 11 provided with separated supports 13, each for one of the elements 105 of the first set 101, 102, 103.
The separation and housing means 3 further comprises a sliding means 17 provided with cavities 19 each having a cross-section approximately reproducing the plan shape of the corresponding element 105 and slidingly engaged by a respective support 13 of base means 11.
The base means 11 carries a plurality of shaped through holes 31 each intended to house in sliding way a head and/or a stem of a guide means 33, for example a bolt whose stem is partially ground and partially threaded, fixed to the sliding means 17. Between the sliding means 17 and the base means 11, elastic means are interposed, for example helical springs acting in compression and preferably associated with guide means 33 which act as a spring guide.
The outer edge 20 with respect to the separation and housing means 3 of said recesses is sharp-edged for better shearing or it is cutting.
The shear means 5 is provided with punches 21 each approximately complementary to a corresponding cavity 19 in which it can slide in a separation condition of elements 105 of first set 101 from the respective frame 107.
This condition begins with the positioning of first set 101, with the link means 108 facing the outside of separation and housing means 3, in contact with the outer edge of cavities 19 of sliding means 17 locked in a protruding condition from base means 11; the subsequent approaching of shear means 5 until the sliding of its punches 21 into cavities 19 causes the detachment of elements 105 from the respective frame 107 and their entrance into the cavities. If elements 105 of first set 101 were connected to frame 107 and also among them by means of respective bridges or if first set 101 consisted of only elements 105, connected each other by respective bridges and without the frame, the cooperation between the sliding means 17 and the shear means 5 would in any case be able to obtain the separation of elements 105 and the entrance of each of them into the respective cavity 19.
In a fixing condition of elements 105 of first set 101 to body C, the latter is interposed between the separation and housing means 3 carrying elements and the facing mesh means 7 carrying the corresponding block means 112 and wherein the sliding means 17 is elastically protruding and free to slide with respect to the base means 11, the approaching of mesh means 7 causes the passage of body C by link means 108 of elements 105 and the engagement and blocking of said link means 108 in seats 113 of block means 112 obtaining the fixing of elements 105 to body C.
The shear means 5 has parallelepiped shape, from a face thereof is protruding a first connection 27 for a movable upper plane of a first press PI and from whose opposite face are protruding the punches 21.
Each punch 21 is provided with housing means 23 for link means 108 of respective element 105.
The shear means 5 is provided with a plurality of clamping means 25, for example consisting of pins projecting towards the separation and housing means 3 and elastically pushed towards the latter 3 by respective compressed helical springs. These clamping means 25 are designed to press and lock the frame 107 against sliding means 17 of the separation and housing means 3 during the separation condition.
The base means 11 is parallelepiped shaped from a face thereof are protruding supports 13, the free end of each of which 13 is preferably shaped in approximately complementary manner to the portion of the corresponding element 105 opposite to respective link means 108.
The mesh means 7 is parallelepiped shaped from a face thereof is protruding a second connection 35 for a movable plane of second press P2 and whose opposite face has a recess 37 shaped in a complementary manner to the plan shape of second set 111 for accommodating, at least partially, the block means 112.
The mesh means 7 is also provided with a set of elastic removable arrest means 39 each bearing a slider 41 sliding in the direction of recess 37 and elastically pressed towards it 37 to match and press an edge of second set 111, elastically and removably retaining it in recess 37.
The shaped recess 37 of mesh means 7, in correspondence of seat 113 of each block means 112 of second set 111 has a riveting means 38 designed to deform and/or block a corresponding link means 108 of a respective element 105 securing it to the corresponding block means 112.
The movement of the shear means 5 towards the separation and housing means 3 can be carried out by means of first light PI press, for example by manual or pneumatic operation.
The movement of the mesh means 7 towards the separation and housing means 3 can be achieved by means of second press P2, for example of toggle type with manual, pneumatic or hydraulic operation.
In this case the empty separation and housing means 3 must be positioned in the first press PI, for example on its fixed plane and, after being loaded with elements 105, must be moved and positioned, for example, onto fixed plane of second press P2; for this purpose, first removable link means 45 and second removable link means 47 are provided.
Each of removable link means, first 45 and second 47, has a parallelepiped shape, from a face thereof a respective connection, third 49 and fourth 51, protrudes respectively for a fixed plane and/or lower plane of first and second press and whose opposite face has a plurality of first positioning means 53, 55, for example each consisting of a pair of protruding hemispheres, complementary to corresponding second positioning means 57, for example consisting of two semispherical cavities complementary to the first positioning means, obtained in or attached to the face of the base means 11 opposite to its supports 13. This configuration allows a fast and precise displacement and positioning of the separation means and housing 3.
The second removable connection means 47 are provided with hollows 59 for free sliding of the guide means 33 fixed to the sliding means 17 while the first removable link means 45 block this sliding; the first removable link means 45 are fixed to a plane of the first press whose facing plane carries the shear means 5, the second removable link means 47 are fixed to a plane of the second press, the plane of which faces the mesh means 7 and said first 45 and second 47 removable link means are fit for receiving and releasing the separation and housing means 3 for placing the latter 3 precisely in the first or second press.
Obviously the invention provides possible alternatives to first 45 and second 47 removable link means and to the use of two presses which must be understood only as an example.
The sliding means 17 has at least two receptacles 63, 65 for guide pins having respective and different diameters and designed to slide in respective and complementary passages 67, 69; 71, 73 obtained in shear means 5 and in gripping means 7.
It should be noted that among other advantages, the device 1 allows to make applications on body of elements in different materials and/or colors.
The invention further provides that the elements can be positioned manually, one by one, in cavities of separation means and housing 3, realizing a sort of hand composition so allowing to carry out applications with a different combination of elements for each body.
By way of example, the parts of the device may be made of steel and machined and/or formed by electro-erosion or 3D printing, for example of a laser-fusion type of metallic powder with an incremental supply.
