Description

FIELD OF THE INVENTION

The present invention relates to a block that can be broken into at least two blocks that can be used to construct structures such as walls and the like.

BACKGROUND OF THE INVENTION

Bricks for the construction of masonry without mortar or the like are already known in the art, which can be firmly clamped together. For example, PCT international application no. PCT / CA96 / 00348 (International Publication No. WO 96/38636, Publication Date December 5, 1996) describes masonry blocks that can be stapled together without being held together by a binder such as a mortar. The block has an upper surface containing a pen element and a lower surface containing a groove element. Both elements are constructed so that when the blocks are stacked, the lower outer side of the block is pinned with the upper outer side of the same block positioned below it, while the upper outer side of the block is pinned with the lower outer side of the block positioned above it.

As described in the aforementioned PCT application, blocks are obtained by mechanically splitting a source block containing a pair of such blocks bonded to its anterior outer surfaces, the anterior outer surfaces being defined by a fracture line running from the upper groove to the lower groove . The problem with said source block is that it is mechanically cleaved by the pressure of the separating device represented by the blade or knife on one of said grooves, requiring considerable pressure. Mechanical splitting of such source blocks requires extensive mechanization, which is expensive, requires maintenance, and requires multiple operators who may be at risk. An additional problem is that the block thus obtained inevitably has the appearance of a broken stone on the front, which is not always desirable.

Other breakable blocks are known which require splitting tools such as chisels or machines such as choppers to split into several blocks. For example, it is possible to refer to U.S. Pat. patent no. No. 697,914 to Griffin, U.S. Pat. patent no. No. 1,872,522 to Stuckey, U.S. Pat. patent no. No. 4,335,549 to Dean, U.S. Pat. patent no. No. 5,496,129 to Dube Holder, U.S. Pat. patent no. No. 5,598,679 to Orton and others and U.S. Pat. patent no. No. 5,688,079 to Bolduc and others;

-2 It is also necessary to refer to patent documents EP-A-0 733 752 and DE-C-826 062, which describe other breakable blocks.

It would be advantageous to have breakable blocks so constructed that they would not require block splitting machines to split them.

It would be particularly advantageous to have a breakable block that could easily be split at the point of use, for example by hand, without the use of tools or separation machines.

It would also be advantageous to have a manually breakable block whose block components would have smooth exterior wall surfaces.

It would be particularly advantageous to have a manually breakable block whose block components would have smooth exterior wall surfaces and which could be manufactured using conventional machinery and molds.

It would also be advantageous to have a manually breakable block to provide a block component in which the breakable bridge means would protect the smooth surface of the outer wall of each block from rubbing during transport and handling.

In accordance with the present invention, for example, a manually breakable connecting component can join the unsecured anterior outer regions.

In accordance with the present invention, for example, a manually breakable connecting component may be located adjacent to the shelves.

According to the present invention, a pair of notches is made to define the break line along which the manually fractured connecting component is fractured.

More specifically, the present invention provides a manually breakable block comprising a first block component, a second block component, and a manually breakable connecting means, said first and second block components each having an unsecured anterior outer region and an unsecured posterior outer region, and

-5 the unsecured front outer area is located below the unsecured rear outer area, each block having an upper outer surface and opposite the lower outer surface thereof, and said upper outer surface defining a feather connecting component and said lower outer surface defining a groove connecting component and a bogie component, wherein said manually breakable bonding means connect said first block component and said second block component, said first block component, said second block component, and said manually broken bonding means configured such that said manually breakable bonding means act as a pivot point around pushing the block component to offset it relative to the second block component and such that said manually breakable bonding means are manually breakable by separating said first block component from said second block component using d the operation of the manual lever on one of said block components relative to the second block component, said operation of the manual lever comprising the grip of the first grip member selected from the group comprising the pen connecting element and the sub-components of the first block component and the grip of the second grip member, which is selected from the group comprising the pen connecting element and the sub-components of the second block component, wherein the block component can be pushed around said pivot point to be displaced relative to the second block component.

In accordance with the present invention, manually breakable coupling means can connect one of said unsecured front outer regions of said first block component to one of said unsecured outer regions of said second block component.

In accordance with the present invention, a manually breakable bridge component can connect the unsecured rear outer region of said first block component to the unsecured rear outer region of said second block component, said first block component, said second block component, and said manually breakable bridge component being formed such that said manually breakable bridge component being manually breakable by separating said first block component from the second said block component using a manual lever operation,

-6includes the grip of the bogie component of one block component and the bogie component of another block component. The block component is then pushed to move it around said rotation point relative to the other block component.

In accordance with the present invention, a manually breakable linking component can connect the unsecured front outer region of said first block component to the unsecured front outer region of said second block component, said first block component, said second block component, and said manually breakable linking component being formed such that said manually breakable linking component being manually breakable in such a way that the first said block component can be separated from the second said block component using the operation of a manual lever, which includes the grip of the pen link component of one block component and the pen link component of the other block component. The block component is then pushed to move it around said rotation point relative to the other block component.

It must be understood here that the term manually breakable means breakable by the hand, as described below, for example.

It should be understood here that the term manual lever operation means that block components can exhibit lever-like functions and can even amplify the force exerted on them. The component block may, for example, be rotated about a longitudinal axis passing through manually fractured bridge means that act as a pivot point. The corresponding part of each block component can be grabbed by hand, for example, either directly or indirectly, and the force exerted can act on the block component or inwardly by pushing the corresponding parts of the block components against each other or by pulling them apart one of the the other. The resulting stress causes the tension around the manually breakable binders and exceeds their strength, that is, the cohesion at the break line, which causes the breakage of the manually breakable binders and consequently the separation of one block component from the other. The parts of each block component that are trapped may be different, that is, the upper part of the first block component and the lower part of the second block component can be trapped, except that the corresponding parts are pushed either against each other or from each other.

As mentioned above, for example, manually breakable binders may include a manually breakable bridge component that connects block components so that they are spaced apart

-7 one from the other. Hand-breakable binders may include, for example, a manually-breakable bonding component. In this case, a manually breakable linking component can bind the block to the components thus. that they are fused together, that is to say, they are adjacent to each other or in close proximity to each other.

It must be understood that manually breakable binders are designed to allow manual breakage of the manually breakable binders and to provide strength or cohesion that holds the block component together during transport and handling before being separated by the user.

The cohesion of manually breakable binders may vary depending on the material of the manually breakable block. The manually breakable block may be made of concrete, clay, aggregate or any suitable material for the mold which is adapted to be broken. For example, a manually breakable block may be made of a concrete mix containing 61% sand, 27% aggregate, 8% cement and 2% admixtures.

The cohesion of a manually breakable block is such that parts of it do not fall off while breaking the manually breakable binder. A manually fractured block can be symmetrical in shape with respect to a longitudinal plane crossing the vertically fractured bridge means at their center point. However, the block may also have a different configuration than the asymmetric shape.

It should be understood here that the term unsecured anterior outer outer region refers to the surface of a block component, which is typically external and unsecured when a structure, such as a wall or the like, is constructed using a plurality of such block components.

It should be understood here that the term smooth surface refers to a surface having a mold-like appearance. The surface of the mold can be smooth, that is, of a uniform appearance, which is the opposite of the appearance of a broken stone.

The block components obtained by the present invention may have an unsecured anterior outer region containing a portion of the front wall with a smooth surface that partially or completely covers the region of the front wall of the block component. In some cases, as mentioned above, a portion of the front wall with a smooth surface after fracturing a manually breakable block may have a portion

-8Walls with rough surface. In some cases, a smooth surface portion of the front wall may be divided by a rough surface portion of the front wall.

It should be understood here that the notch term refers to a parapet, such as a line or groove on the surface, which by creating a continuous surface localizes the fracture at the fracture point and permits normal fracture along the fracture line defined by a pair of such notches.

The present invention will now be described by means of drawings illustrating embodiments of the present invention.

Referring now to the drawings, and in particular to Drawing 1, it shows the source block 10 as described in the above-mentioned PCT International Application. The source block 10 contains a pair of blocks 11, 12, which are connected on their front outer surfaces, the front outer surfaces being defined by a break line running from the upper groove 13 to the lower groove 14. Blocks 11,12 each have a corresponding upper outer a surface 15 comprising a pen connecting element 16, a shelf 17 and a corresponding lower outer surface 18 comprising a groove connecting element 19 and a bogie element 20. The feather connecting element 16 and the groove connecting element 19 may be formed such that when stacking blocks 11 and 12 one top of the other, the lower outer surface 18 of the block 11 may rest on the upper outer surface 15 of the block 12 located below, while the upper outer surface 15 of the block 11 may rest on the lower outer surface 18 of the block above it.

Referring now to FIGS. 2 and 3, they show an example of a manually breakable block in accordance with the present invention. The manually breakable block 21 comprises a first block component 22, a second block component 23 and a manually breakable bridge means 24 connecting the first block component 22 and a second block component 23. In the example shown here, the manually breakable bridge means 24 is a manually breakable bridge component 24 which connects the first and

-11Other block component. Since the first and second blocks of components 22, 23 are essentially the same when separated, their components will hereinafter be denoted by the same numbers.

Each first and second block component 22, 23 comprises a first lateral outer surface 25 and a second lateral outer surface 26 opposite the first lateral outer surface 25. Each first and second block component 22, 23 comprises an upper outer surface 27 extending longitudinally from of the first lateral outer surface 25 to the second lateral outer surface 26. The upper outer surface 27 defines a pen connecting component 28, a shelf 29, and a first intermediate outer surface 30 connecting the pen connecting component 28 and a shelf 29. The lower outer surface 31, which is opposite the upper outer surface 27 extending longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26. The lower outer surface 31 defines a groove connecting component 32, a sub-component 33, and a second intermediate outer surface 34 connecting the groove connecting component 32 and a sub-component 33.

The unsecured front outer region 35 extends logitudinally from the first lateral outer surface 25 to the second lateral outer surface 26. The unsecured anterior outer region 35 connects a shelf 29 of the upper outer surface 27 and a base component 33 of the lower outer surface 31. The unsecured anterior outer outer region 35 comprises an unsecured portion 36 front walls with smooth surface. In the example of the manually breakable block 21 shown here, the front wall portion 36 has a smooth surface, substantially the entire area of the front wall 35, i.e., the front wall area 35 has a completely smooth surface. The unsecured front outer region 35 is vertically downward relative to the pen connecting component 28 (as well as to the unsecured rear outer region 37).

Each first and second block component 22, 23 also comprises an unsecured rear outer region 37. The unsecured rear outer region 37 extends longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26. The unsecured rear outer region 37 connects the groove connecting component 32 of the lower outer surface 31 and the feather connecting component 28 of the upper outer surface 27. The example of the manually breakable block 21 shown here is designed such that the rear wall regions 37 are facing one another. Each unsecured rear outer region 37 includes a portion 38 of the unsecured rear wall with a smooth surface, which in the example shown divides it into

-12two parts of the manually breakable bridge component 24, respectively, on the part above and on the part below the manually breakable bridge component 24.

The manually breakable bridge component 24 extends longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26. However, for example, the manually breakable bridge component 24 may be shorter or disconnected, i.e. divided into two or more spaced sections of the bridge component . As can be seen, the manually breakable bridge component 24 connects the unsecured rear outer region 37, that is to say, that part of each unsecured outer region 37 is hidden by the manually breakable bridge component 24. The hidden part becomes visible only when the manually fractured bridge component 24 breaks, as will be further described below.

In the example shown here, the manually fractured bridge component 24 is located in the middle between the groove connecting component 32 and the pen component 28 of each block component 22, 23. However, the manually fractured bridge component 24 may be located anywhere between the groove component 32 and the pen component 28 of each block component 22, 23.

Referring now to FIG. 4, this drawing shows an enlarged view of a manually fractured bridge component 24 of the example of a manually fractured block 21 of FIG. 3. As can be seen, the manually fractured bridge component 24 has a first notch 39a located between the manually fractured the bridge component 24 and part 38 of the unsecured smooth surface of the rear wall adjacent to the pen connecting component 28 of the first block component 22. The second notch 39b is opposite the first notch 39a between the manually fractured bridge component 24 and the rear wall portion 38 with a smooth surface which is located next to the groove connecting component 32 of the first block component 22. The first and second notches 39a, 39b form a pair of opposite notches defining the first break line, as shown by the dashed line marked with the letter A. The third notch 39c is located between the manually breakable bridge component 24 and the part 38 of the unsecured smooth surface of the rear wall adjacent to the feather connecting component 28 of the second block component 23. The fourth notch 39d is opposite the third notch 39c between the manually fractured bridge component 24 and the portion 38 of the unsecured smooth surface of the rear wall adjacent to the groove connecting component 32 of the second block component 23. The third and fourth notches 39c, 39d form a second pair of opposite notches defining the second break line, as shown by the dashed line indicated by letter B. In the example shown here, notches 39a, 39b, 39c, 39d extend

-13longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26, that is, along the manually breakable bridge component 24. Although the example shown here is provided with notches 39a, 39b, 39c, 39d, the manually breakable block 21 may alternatively be free from such comma.

Referring now to FIG. 4A, this drawing shows an enlarged side view of the manually fractured bridge component 24 of FIG. 4. As mentioned above, the manually fractured bridge component 24 is designed to allow its manual breaking while simultaneously provides sufficient strength or cohesion to hold together the first and second block components 22, 23 during transport and handling of the manually breakable block 21.

As mentioned above, cohesion of the manually breakable bridge component 24 may vary depending on the material of the manually breakable block. Hand-breakable bridges have correspondingly 24 dimensions, which vary depending on the material used and the composition of the material. For example, in the case where a manually breakable block 21 is made of a concrete mix in which 61% sand, 27% aggregate, 8% cement and 2% additives, the dimensions of the manually breakable component 24 may be as follows. These dimensions are given for the manually breakable bridge component 24 extending from one side outer surface to the other as shown here. The dimensions of a manually breakable bridge component may be different if the manually breakable bridge component is shorter or broken than mentioned above. It is important to note that these dimensions are given with respect to the example of a block 21 with a height of 150 mm, indicated by the arrow P in Figure 3, with a thickness of the block component 65 mm, indicated by an arrow Q and a length of 230 mm, measured from the first to the other lateral outer surface 25, 26. These dimensions are given here by way of example only.

The manually breakable bridge component 24 of Figure 4A has a length indicated by an arrow L, preferably up to about 55 mm. The length L may preferably be 8 mm. The manually fractured bridge component 24 has a thickness measured at the line of fracture between the upper surface and the lower surface. In the example shown here, the manually breakable block 21 has two such break lines, indicated by the arrows T _A and T _B. The thickness at one break line may vary from 4 mm to 25 mm and is preferably 6 mm. The thicknesses at the first break line T _A and at the second break line T _B may be similar as shown here. However, the thickness at the first break line T _{A may be} different from the thickness at the second break line T _B , insofar as the manually breakable bridge component 24 is manually breakable at one break line and is breakable at the second break line using a tool such as a hammer .

-14The thickness of the manually breakable bridge component 24 between two break lines, indicated by an arrow with the letter T _c , is greater than the thickness of the manually breakable bridge component 24 at the break line when there is more than one break line or greater than the thicker break line in the case where there are two break lines of different thicknesses. The thickness T _c is preferably 1.4 times greater than T _A or T _B. In the example shown here, the thickness T _{c is} preferably 12 mm.

The manually breakable bridge component 24 may be of any configuration that allows it to be broken manually. For example, a manually breakable bridge component 24 may have a configuration as shown by line D. The manually breakable bridge component 24 may also be of the configuration shown by the dash line E or the dotted line F.

Referring again to Figure 3, the example of a manually breakable block shown here can be broken as follows. The first and second block components 22, 23 may be gripped (by hand), for example, around their base components 33. Components 22, 23 may be gripped directly or indirectly. The operation of the manual lever by pressing the block of components 22, 23 may be used by pointing the bogie component 33 towards each other as indicated by arrows 13A. In this case, the block components 22, 23 can act to exhibit a lever function and can even amplify the force exerted on them. The operation of the hand lever causes tension, for example, around the notch 39a, which exceeds the cohesive force of the manually breakable bridge means 24 at the first break line. The block components rotate about the longitudinal axis of the manually breakable bridge means that act as a pivot. The manually breakable bridge means 24 are broken along the break line from the first notch 39a to the second notch 39b, followed by the separation of the first block component 22 from the second block component 23, as shown in Figure 3A.

Alternatively, the (manual) force on the block component acting outwards, i.e. in the direction of arrows 13B, can be applied, pulling them apart. The resulting stress causes tension around the second notch 39b and causes the manually fractured bridge component to break from the second notch 39b along the first break line to the first notch 39a, followed by the separation of one block component from the other. The grip portion of each block component may be different, i.e., the upper portion of the first block component and the lower portion of the second block component may be grasped, only to be pulled together or pulled apart from each other.

15 Referring now to FIG. 3A, fracture of the manually breakable bridge component 24 detects a rough surface part 40 on the manually breakable bridge component 24 and a rough surface portion 41 of the rear wall on the first block component 22 to which the manually breakable bridge component was secured. In the event that a manually fractured bridge component, or part of it, remains attached to one of the block components, it can be bounced away, for example with a hammer. For example, the user may deduct a manually fractured bridge component 24 by striking it in the direction of arrow 14A, causing the manually fractured bridge component 24 to be broken along the second fracture line and to remove the manually fractured bridge component 24 or its attached portion from another block component 23, such as shown in Figure 3B. Other suitable means may also be used to remove the manually breakable bridge component 24 or a portion thereof that is attached to one of the block components.

As a result of a fracture of a manually breakable block 21, block components can be obtained as described in the PCT International Applications described above, the entire contents of which are incorporated herein by reference.

Referring now to Figure 5, this drawing shows another example of a manually breakable block 21 in accordance with the present invention, the configuration of which differs from the configuration of Figure 2 in that the manually breakable bridge component 24b is located next to the pen connecting component 28 of each block components 22, 23. In the example shown here, part 38 of the unsecured rear wall with the smooth surface of each region 37 of the rear wall is not divided by a manually fractured bridge component 24b. The first and third notches 39a ', 39c' are between the manually breakable bridge component 24b and the feather connecting component 28 of the corresponding block component 22, 23, while the second and fourth notches 39b ', 39d' are located between the manually breakable bridge component 24b and the part 36 rear walls with rough surface corresponding to block component 22, 23.

Figure 6 shows another example of a manually breakable block 21 according to the present invention, whose configuration differs from the previously described blocks in that the manually breakable bridge component 24c is adjacent to the groove connecting component 32 of each block component 22, 23. As in the case of the block from Figure 5, a portion of the surface 38 of the rear wall of each region of the rear wall 37 is not divided by a manually fractured bridge component 24c. The first and third notches 39a, 39c are located between the manually breakable bridge component 24c and the rear wall portion 38 with the smooth surface of the corresponding block component 22, 23, meanwhile

-16 where the second and fourth notches 39b, 39d are located between the manually breakable bridge component 24c and the groove connecting component 32 of the corresponding block component 22, 23.

The example of a manually breakable block 21 of FIG. 6 can be broken as follows. The first and second block components 22, 23 are grabbed (by hand) for example around the respective bogie components 33. Then, the operation of the manual lever is applied by pressing the block component 22, 23 by pointing the bogie component 33 towards each other as shown with arrows 16A. The operation of the hand lever causes a tension, for example, around the first notch 39a, which exceeds the cohesive force at the first fracture line and causes the fracture of the manually fractured bridge component 24c along the first fracture line from the first notch 39a to the second notch 39b, followed by separation of the first block component 22 from the second block component 23 as shown in Figure 7. A similar result can be obtained if each block component 22, 23 is trapped around the corresponding pen connecting component 28 and then pressed on the component block 22, 23 by pulling the pen connecting components apart one from the other, as shown by arrows 16B in Figure 6.

Referring now to Figure 7, a break of the manually breakable bridge component 24c discloses a rough surface portion 40 'of the manually breakable bridge component 24c and a rough wall portion 41' of the rough surface on the block component 22 to which the manually breakable bridge component 24c was attached.

The manually breakable bridge component 24c may then be removed by bouncing it away as described above in Figure 3A.

Referring now to Figure 8, it shows the block components 22, 23 obtained by breaking the example of the manually breakable block 21 of Figure 3. As mentioned above, the block components 22 and 23 are essentially identical after the break. The first block 22 is facing so that its second outer side surface 26 is now facing the sheet plane. As can be seen, the first block component 22 is mounted above the second block component 23 by folding, thereby firmly clamping to one another. The smooth surface 36 of the front wall completely covers the area 35 of the front wall of each block component 22, 23, while their areas 37 of the corresponding rear walls comprise a smooth surface portion 38 divided by a rough surface portion 41.

-17Figures 9 and 10 show another example of a block according to the present invention. In this case, the manually breakable linking component 24d is associated with the corresponding unsecured front outer regions 35, i.e., the unsecured rear outer regions 37 are not associated with the manually breakable linking component 24d. The unsecured anterior outer regions 35 face each other. The manually breakable linking component 24d is adjacent to the shelf 29 of each block component 22, 23. Each unsecured anterior outer outer area 35 comprises an unsecured portion 36 with a smooth surface located below the manually breakable linking component 24d and a rough surface that is masked manually breakable connecting component 24d. However, the unsecured anterior outer regions 35 fully show when the block components are separated from each other, as will be further described below.

Figure 11 shows an enlarged view of a manually breakable linking component 24d of a case of a manually breakable block 21 of FIGURE 10. The manually breakable linking component 24d contains a pair of notches 43, 44 opposite each other and located above and below. The notches 43, 44 extend longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26, as seen in FIG. 9. The notches 43, 44 define the break line extending from the first notch 43 to the second notch 44, as indicated by the dashed the line along which the manually breakable connecting component 24d is breakable.

Figure 12 shows another example of a manually breakable block 21 according to the present invention, whose configuration differs from the configuration of the block example of Figure 9 in that the manually breakable connecting component 24d is adjacent to the base component 33 of each block component 22. 23. The corresponding smooth surface front walls 36 are now located above the manually breakable connecting component 24d.

13 shows another example of a manually breakable block 21 in accordance with the present invention, the configuration of which is different from the configuration of the block examples of FIGS. 9 and 12 in that the manually breakable connecting component 24d is located in the middle, i.e. equal to the distance between the shelf 29 and the bogie 33 of each block component 22, 23. However, the manually breakable coupling component 24d may be located anywhere between the shelf 29 and the bogie 33. The front wall portion 36 of the smooth surface of each block component 22, 23 is manually divided the breakable connecting component 24d, i.e., the smooth wall portion 36 of the smooth surface is divided into two parts located above and below the manually breakable connecting component 24d.

-18Recalling FIG. 14 now, the manually breakable block 21, as described above, can be broken by trapping each block component around the corresponding pen connecting component 28 and using the operation of the hand lever in the direction of arrows. of component 24d reveals a portion 42 of the front wall with a rough surface of each block component 22, 23. A similar result is obtained by engaging a block of components 22, 23 around the corresponding bogie components 33 and using the lever action in the direction of arrows 14B.

Figure 15 shows another method of breaking a manually breakable block 21 into the first and second block components 22, 23. The block components 22, 23, for example, are gripped around the corresponding pen connecting components 28 and the operation of the manual lever is used by pulling the pen coupling components 28 apart in the direction of arrows 15A. A similar result is obtained by grabbing a block of components 22, 23, for example, around the bogie components 33 and using the operation of the hand lever by pushing the bogie components 33 against each other, as shown by arrows 15B.

Referring now to Figure 16, after separation of the block components 22, 23, the unprotected area 35 of the outer front surface is part 36 of the unprotected front wall with a smooth surface and part 42 of the front wall with a rough surface. The rough wall front portion portion 42 extends from the front wall region 35 and extends longitudinally from the first lateral outer surface 25 to the second lateral outer surface 26. Because the rough surface front wall portion 42 results from a fracture of the manually fractured bridge component 24d, it has the appearance of broken stone .

Figure 17 shows the first block component 22 and the second block component 23, which are obtained by breaking the manually breakable block 21 of Figure 10, which are stacked on top of one another and thus firmly fastened. The second block component 23 is rotated 180 ° so that the second outer surface 26 is now facing the sheet plane.

18 shows how a plurality of identical block components 22 and 23, obtained by breaking the manually breakable blocks 21 of FIG. 10, can be stacked with the intention of constructing a wall or the like without the use of a bonding agent such as a mortar. As can be seen from the example shown, part 42 of the front wall with a rough surface has the appearance of broken stone, while part 36 of the front wall with a smooth surface has the appearance of a smooth surface.

[19] Referring now to FIG. 19, an example of a manually breakable block 21 'according to the present invention containing more than two block components is shown. In the example shown in this drawing, the manually breakable block 21 'comprises a first block component 49 which is connected to the second block component 50 by the first manually breakable connecting means 51 in a configuration similar to the embodiment of the manually breakable block of FIG. says that the manually breakable bonding means 51 connect the front wall areas 35 of the first and second block components 49, 50 located near their shelves. However, the configuration of the manually breakable block 21 'is different in that the second block component 50 is connected to the third block component 52 by another manually breakable bridge component 53, i.e., the second manually breakable bridge component 53 connects the unsecured outer region 37 of the rear the walls of the second block component 50 and the unsecured outer region 37 of the rear wall of the third block component 52 near their groove connecting components 32. The fourth block component 54 is connected to the third block component 52 by a third manually breakable bridge component 55. A manually breakable bridge component 55 connects the area the front walls 35 of the third block component 52 and the front wall area 35 of the fourth block component 54 near their shelves 29.

Referring now to FIG. 20, the advantage of the manually breakable blocks 21 shown in FIGS. 10, 12 and 13 is that they can be manufactured using conventional mechanization and molds, such as the machines and molds for making the source blocks described above; said PCT international application describing the V3-12F Vibrapac separating machine manufactured by Besser. As can be seen in this drawing, a modification of the present mold, such as inserting a nozzle 56 opposite the notch 43 inside the mold, is required to provide parts of the 36 front walls with a smooth surface in the areas 37 of the front walls of the case of the manually breakable block 21 of FIG.

Referring now to FIG. 21, another example of a manually breakable block 21 according to the present invention is shown. The manually breakable bridge means is a manually breakable connecting component 24e. As mentioned above, the manually breakable connecting component of the region of the rear wall of the first and second block components 22, 23 connects so that they are fused together, that is to say, they are directly adjacent or in close proximity to each other. In the example shown here, the manually breakable connecting component 24e connects the regions 37 of the rear walls of the block components 22, 23 which, in addition to the corresponding pen components 28. The opposite notches 45, 46 define a break line marked by a dotted line along which the manually breakable can be broken. the connecting component 24e breaks.

-20Figure 22 shows a block of components 22, 23 obtained by breaking block 21 of FIG. 21 and stacked together to securely fasten one another.

Figure 23 shows another example of a manually breakable block 21 in accordance with the present invention. The configuration of the block 21 example shown here differs from the block 21 examples described above in that the manually breakable connecting component 24f connects the lower surface 31 of the first block component 22 and the upper surface 27 of the second block component 23. In more detail, the manually breakable connecting component 24f connects the second central outer surface 34 of the lower outer surface 31 of the first block component 22 and the first central surface 30 of the upper outer surface 27 of the second block component 23. The manually fractured connecting component 24f comprises a first notch 47 and a second notch 48 opposite to the first notch 47 and defining the break line along which the manually breakable coupling component 24f may break.

Figure 24 shows a block of components 22, 23 obtained by breaking block 21 of Figure 23, which are stacked together and thus firmly fastened.

25 shows another example of a manually breakable block 21 'in accordance with the present invention. The manually breakable linking component 24g connects the front outer unprotected region 35 of the block component 22, 23. The first block component 22 is longitudinally inverted compared to the case of the blocks 21 described above. In other words, the upper outer surface 27 of the first block component 22 is adjacent to the lower outer surface 31 of the other block component 23 and vice versa. The first notch 47 is located next to the front wall area 35 of the first block component and the upper outer surface 27 of the second block component 23. The second notch 48 is located opposite the first notch 47 next to the upper outer surface 27 of the first block component 22 and the front wall area 35 of the second block component 23 .

A further advantage of blocks, such as the examples of manually breakable blocks 21 shown in Figures 10, 12, 13 and 19, that is, with the manually breakable bridge means 24 connecting the regions 35 of the front walls of the block components 22, 23 is that by keeping the distance, the front wall portions 36 of the smooth surface of the front wall regions 35 are protected by manually breakable bridge means 24 from rubbing each other during handling and transportation so that they remain intact until end use.

Although certain examples of manually broken blocks in accordance with the present invention have been illustrated and described, it should be understood that the present description is made by way of example only and that various other embodiments still within the scope of the invention are possible, as described in the invention. the following claims, the contents of which are considered to be invention.
