Abstract

The device for making molded sandcastles having complex shapes (3) comprises four pieces (1) which, assembled together by adjusting their returns (4) and holding them by clamps or sliding hoops leave an inlet hole for the sand in the mold top and an evacuation hole for the overflow of water in its bottom.

Description

The present invention relates to a device for performing

  wet sand "blocks" with complex shapes.

  Traditionally, buckets and utensils allowing molds to be made from wet sand do not give the possibility of having reliefs on each face of said shapes. When using a bucket to make a wet sand molding, the only reliefs that can be obtained will be on an axis parallel to the demolding axis. For example, it is possible to obtain slots on the upper face of the cube made of wet sand, but any relief on the four lateral faces of the cube would be destroyed during the

1 0 demolding.

  The device according to the invention overcomes this drawback. Indeed, the mold does not consist of a single part (like a bucket for example) or two parts, but four separate parts each with two returns to 45

allowing their perfect assembly.

  When they are assembled and held by clamps and / or sliding straps, the arrangement of these four parts makes it possible to introduce, from above, the sand,

water or wet sand.

  To adjust the hydration of the sand contained in this mold and its distribution in each relief, the user can add as much water as he wishes, knowing that the four separate parts also leave an opening at the bottom of the mold for the evacuation of

too full of water.

  During demolding, after removing the clamps and / or the sliding retaining straps, the user can move each part aside by sliding it on an axis

  perpendicular to the axis of the form made of wet sand.

  According to particular embodiments: - The four parts making up the mold can be assembled while remaining vertical or oblique and can have variable dimensions depending on the model that is

wants to achieve in sand.

  - The two returns to 450 of each piece forming the mold may include protuberances in the form of streaks, hemispheres or any other form deemed useful for perfect assembly. These protrusions will be on one of the returns to 45 of shape

  "male", and, "female" on the second return of each piece.

  - The pliers used, the number of which may vary depending on the model, for

  holding the four pieces of the mold could be "clothespins".

  - The four parts forming the mold can be made of rigid plastic. - The four pieces forming the mold can be stackable to reduce their size.

  - Depending on the model, sliding straps can hold the mold so that 40 the weight of the sand does not spread the four parts of it.

  -2 - On second use, the mold may be filled with snow or any other

powdery material.

  The accompanying drawings illustrate the invention: - Figure 1 shows the mold assembled and held by clamps, seen in profile, - Figure 2 shows the open mold, seen in profile, - Figure 3 shows the mold assembled and held by pliers, seen from above, - Figure 4 shows the open mold, seen from above, - Figure 5 shows an example of wet sand mold (Monument), open, with complex shapes and reliefs, - Figure 6 represents the closed mold and held at its base by a sliding hoop. With reference to these drawings, the device comprises four parts (1), clamps (2)

  and / or sliding straps (11) making it possible to hold the parts (1) assembled 20 to form the wet sand mold (3).

  The four parts (1) of the mold, which can be made of plastic, either injected or thermoformed depending on the model chosen, each have two returns (4) forming an angle between 400 and 500 with said parts, allowing the

  good positioning of these, 450 being the most common angle of returns.

  Each return to 450 (4) has protrusions, male (5) or female (6), allowing perfect assembly before final fixing, by clamps (2) and / or

  sliding strapping (11), for filling.

  The sliding straps (11) consist of a solid and rigid part which envelops the perimeter of the mold when the latter is closed. At each angle of the 30 straps, slots (12) as wide as the sum of the thicknesses of the two returns to 450 (4) allow the two returns to be inserted at 450 (4) so that they cannot come off one on the other under the pressure of the weight of wet sand. The mold is thus motionless,

  which allows a good realization of the pâté.

  When the mold is assembled and fixed, the user can start filling 35 by the top passage (7) of the closed mold.

  If the user introduces too much water, it will be able to drain

  through the opening (8) at the bottom of the closed mold.

  When removing from the mold, after removing the clamps and / or the straps

  sliding (11), the user will slide the four parts (1) along an axis of demoulding (9) perpendicular to the vertical axis (10) of the object molded in wet sand (3).

  The device according to the invention is particularly intended for the manufacture of pâtés

  wet sand with complex shapes.

Claims (4)

  1) Device for making wet sand pies having complex shapes, characterized in that it comprises four parts (1) which, assembled together by adjusting their returns (4), (returns forming an angle between 400 and 50 with said part), and holding by pliers (2) and / or sliding straps (11) leave an inlet (7) for the material at the top of the mold and an outlet ( 8) water overflow at the bottom of it.   2) Device according to claim 1, characterized in that the tightening of the four parts (1) forming the mold is done using sliding straps (11) 15 consisting of a solid and rigid part which envelops the perimeter of the mold when it is closed.   3) Device according to claim 2, characterized in that the sliding straps (l1) have slots (12) at the four corners as wide as the sum of the thicknesses of the two returns (4) which join at each angle of the mold so to be able to slide from top to bottom of the latter and come to position to maintain the four parts (1) in the closed position during filling. 4) Device according to claim l or claim 2, characterized in that the release of the four parts (1) is carried out by removing the clamps (2) and / or the sliding straps (l 1) by sliding them along returns (4) from the bottom to the top of the mold and spreading the said pieces along an axis (9) perpendicular to the vertical axis (10) of the sand block (3) produced. 30   ) Device according to any one of the preceding claims, characterized in that the four parts (1) forming the mold can have variable shapes depending on the models (historic monuments, buildings or animals by   example) and returns (4) forming an angle of 450 with said part. 35 6) Device according to claim 5, characterized in that each return (4) has protuberances, male (5) or female (6), allowing perfect assembly before final fixing, by clips (2) and / or straps sliding (l 1), for filling.
