Description

[Detailed description of the invention] The present invention makes it possible to assemble the same boxes together.

A box with tiers, more particularly with at least two substantially planar and parallel faces which, when engaged slidingly parallel to these faces, form a clamping assembly with other identical boxes. This relates to boxes that are equipped with mortises and tenons that allow attachment. It is already known to provide rectangular boxes with mortises and tenons that allow them to be assembled one after the other. Such boxes are particularly used for general organization, specifically for organizing or packaging screws, small electrical parts, magnetic tape cassettes, fishing gear, etc. However, the mortise and tenon grooves provided in these known boxes extend over the entire width of the box.Such examples have various disadvantages, and these disadvantages can be seen both in terms of use and manufacturing. Since a certain amount of clearance is required to allow the tenon to fit into the mortise groove over the entire width of the box, it is necessary to tilt the box in relation to the other box almost every time it is assembled or removed. This causes the bay to be blocked, and this blocking occurs many times over the length of the setting stroke. Two types of such fitting mortises and tenons are known.

The first type is a rectangular convex stopper with slopes on each of its long sides, which can be fastened to a mating concave stopper, and the slopes are in opposite directions. .

During the manufacturing process commonly carried out in molding, the mortise and tenon of the molding must be removed from the mold by sliding the product over the entire length of the mortise and tenon. This method is slow and can cause seizing or destruction of the product during the sliding operation. In order to overcome these disadvantages, in the second type of known mortises and tenons, the slopes are parallel and do not face each other, so that at least two pairs of tenons are required to assemble two products. , mortise and tenon are required.

However, during production, this method does not require sliding over long distances for die cutting. But on the contrary,
A mold consisting of movable parts of the same length as the tenon and tenon is required, and these movable parts are called "drawing parts" and are necessary for die cutting. This type of mold has the disadvantages that it is complex, expensive and fragile compared to molds without moving parts. Such molds generally consist of fewer cavities and therefore parts made per molding than molds without such moving parts, and therefore have fewer moving parts and less space required for their movement. becomes larger. The present invention aims to solve the above-mentioned disadvantages.

In the box of the present invention, the mortise and tenon groove are formed in two parts of at least one linear segment having a length equal to the dimension of the surface measured in the assembly direction, and the two parts are formed in the straight line. It is characterized by being shorter than the length of the segment and being provided at the end of the segment.

Since the tenon and tenon grooves are short, the fitting stroke is short, and even if the fitting is tilted slightly, the fitting stroke will not be prevented from sliding.

Furthermore, all. Since the tenon and tenon grooves are fitted almost simultaneously, each fitting acts as a centering means for another fitting located on the same line, so that the above-mentioned inclination is reduced. Furthermore, since the insertion stroke has been shortened, only a short distance of friction needs to be overcome. As a result, play can be reduced, resulting in tighter assembly and better guidance during each fit. In terms of manufacturing, since the mortise and tenon grooves are short and they are provided at the edge of the box, it is necessary to cut out the mortise and tenon grooves. Not only can molds with embossments not be used, but the total number of mold cavities and therefore the total number of products can be increased. Next, the present invention will be explained in more detail with reference to the accompanying drawings.

The illustrated box is a rectangular parallelepiped with two large parallel surfaces 1 and 2 provided with inset mortises and tenons.

The box is open on one of its narrow sides 3 to allow the insertion of drawers or the attachment of a lid. These drawers or lids are not shown. Surface 1 carries six tenons, which are arranged in three pairs: 4 and 5, 6 and 7, 8 and 9. The tenons of each pair are aligned in the insertion direction parallel to the short side of surface 1 and are in contact with the long side of this surface 1. The length of the groove is only a portion of the width of surface 1. In the illustrated example, the combined length of the two tenons is only a portion of the width of surface 1. A sloped portion 10 further extends between the tenons 6 and 7, and this sloped portion 10 rises in the direction from the tenon 6 to the tenon 7. A notch portion 11 is provided subsequent to this inclined portion 10. Ends of tenons 4, 6 and 8, each 4a
, 6a, and 8a, as will be understood from the explanation of assembly described later.
A slight bevel is provided to make it easier to engage the tenon into the mortise groove. The face 2 of the box is provided with six mortises and tenons, which are arranged in a manner similar to and interlocking with the tenons 4 to 9 described above.

These grooves 13, 15, 17 have grooves 18, 19, 20.
are provided in each case successively, and these rectangular open grooves allow the pre-engagement of other similar box tenons 4, 6, 8, respectively. A protrusion 21 is further provided between the mortise groove 14 and the groove 19, forming a sawtooth on the surface of the face 2. This serrated projection 21 engages with the notch 11 of the mating tenon at the end of the assembly process. Furthermore, the entrance portion 12a of the mortise groove 12, 14, 16,
14a and 16a are each slightly widened to facilitate the insertion of tenons 5, 7 and 9, respectively. Next, the assembly of two identical boxes will be explained with reference to FIGS. 4 to 7.

First, as shown in Figures 4 and 5, the boxes are placed on each other at shifted positions, so that the tenons 4, 6, and 8 of box A are engaged with the open grooves 18, 19, and 20 of box B, respectively. Make sure to enter the room. Slide box A over box B in the direction of the arrow below. Then, tenons 4, 6, and 8 of box A are grooves 18, 19, and 20 of box B.
are guided by the mortise grooves 13, 15, and 15 of box B.
17. At the same time, tenons 5, 7, and 9 of box A are
As shown in the figure, they engage with the mortises 12, 14, and 16 of box B, respectively. At or slightly after this engagement, the inclined portion 10 of the box A comes into contact with the protrusion 21 of the box B, creating a certain amount of resistance. Even though this resistance is felt, box A is moved relative to box B. When a slight force is applied, the inclined portion 10 of box A moves away from the protrusion 21 of box B due to the elastic deformation of the walls of both boxes. Eventually, the protrusion 21 engages in the notch 11 and comes into contact with the vertical side surface of the notch 1, as shown in FIG. Further boxes can be attached to the box assembly by assembling either box A or B in a similar manner. The invention is capable of numerous variations and embodiments without departing from its scope.

In particular, it is possible to omit the tenons 6, 7 and the mating mortises ]4, ]5, and to fit the boxes together using only four tenons and tenons. Furthermore, it is not necessary that all the tenons be located on the same side of the box.

According to another embodiment of the invention, tenons 4, 6 and 8 are provided with mortise grooves, while tenon 7 is omitted. On the opposite side of the box, tenons are provided in place of the mortises 13, ]5, ]7, while the mortises 14 and the open grooves 18, 19
, 20 are omitted. Instead of the tenon 7, a projection similar to the projection 21 is provided, which cooperates with a recess in the other box, which is also provided instead of the tenon groove 14. According to this embodiment, molding can be made even easier. Also, a pair of tenons 6, 7 and mortise grooves 14,]5
It is also possible to obtain the desired box fitting by providing only one.

However, this is only possible if the tenons and tenons are formed sufficiently large. However, according to this embodiment, molding can be further simplified. The box of the present invention can generally be used for organization.

In particular, it can be used for organizing or packaging recording magnetic tape cassettes, screws, small electrical parts, fishing gear, etc. The present invention is not limited to rectangular boxes, but can be applied to boxes of any shape with two parallel sides, or the outline of the box can be any polygon, i.e. circular or oval. It's okay.

Furthermore, the two assembly surfaces are not parallel but at an angle, so that it is possible to assemble a plurality of boxes in such a way that an arc is drawn. Furthermore, although the two assembly surfaces are parallel, the two consecutive surfaces are slightly offset from each other in the longitudinal or vertical direction, so that when multiple boxes are assembled, the two boxes form a kind of staircase. It can also be assembled.

Furthermore, by combining the above two embodiments, that is, the example where the two surfaces are not parallel and the example where the two surfaces are assembled in a slightly shifted state,
A spiral box assembly can be formed.

The advantage of this embodiment is that an unlimited number of boxes can be assembled. In order to obtain the advantages of the three embodiments described above in a box with non-parallel and non-longitudinally offset surfaces, a box with non-parallel and/or longitudinally offset surfaces that is the same as the box with which it is assembled is to be used. Parts with two planes with mortises and tenons can be continuous.

Such intermediate parts are installed one by one between each successive box of an assembly to form the box assembly in the form of an arc, a staircase, or a spiral. Furthermore, the surfaces provided with the assembly tenons and tenons do not need to be flat, and may be curved to some extent.
