Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for connecting a drawer portion.

[0002]

2. Description of the Related Art When furniture with a drawer having a drawer bottom plate, front, back and side plates is continuously manufactured, the front,
The individual drawer parts, such as the back and sides, are generally prefabricated and assembled to the desired drawer in the final assembly step.

In order to obtain the most suitable assembly of the individual drawer parts in such a production, and in order not to impair the stability of the drawer, separate fittings have heretofore been used.
It was used to join the drawer parts together.

All known parts for connecting pull-out parts are specially manufactured and, in a unique assembly process, are first screwed or glued onto one of the at least two parts to be joined together. Or be fitted.

A large number of parts must be assembled and placed in place for pre-assembly. At this time, the mounting parts and screws necessary for mounting remained in the completed drawer, and the appearance of the drawer was often unsightly and dirty.

Therefore, in order to beautify the shape, the drawer rail 1
Special attachments for attaching books to front and back plates are well known. The fitting was simply screwed or nailed to one of the drawers to be joined or attached by any other suitable method, each time the front end of the rail being inserted therein.

[0007] Also, with respect to these mounting parts, there is the disadvantage that a large number of parts must be handmade before the actual mounting of both drawer parts is completed. In addition, the connection of the insertion mechanism is unstable, and there is a disadvantage that the rail must be firmly fixed to the mounting component by using a large screw or nail depending on the insertion mechanism when necessary. Moreover, the assembly of the drawer portion has often been wasteful due to many factors thus impeding the rational continuous manufacture of drawers. Moreover, this known mounting part was rarely used because the back plate was not suitable for a drawer made of thin steel plate in terms of cost.

[0008] Therefore, a technical idea for creating a mounting structure, that is to say a mounting structure which, due to the two drawer parts, ensures a secure connection from all sides quickly and can be manufactured reasonably and at an advantageous cost. There is a problem.

[0009]

SUMMARY OF THE INVENTION In the present invention, the integration of materials forms a mounting structure in the manner of interlocking by insertion and rotation. As a result, both connecting parts are prevented from moving by the mutual insertion of the individual connecting parts, and the directions other than the insertion are fixed. Then, the associated rotational movement of the mutually inserted parts makes it possible to reduce the number of attachment parts in the insertion direction, so that a reliable attachment is completed towards all sides.

Since the plug-in and rotary-joint parts are joined by means of a corresponding withdrawal part and in each case an integral part of the material, the assembly of additional screws, nails and other parts is eliminated, and the individual complications of using them. There is also no need for easy handling.

A great effect obtained by the present invention is that, when taking as an example the production using cutting and punching of a drawer back plate made of a thin steel sheet at the same time, a mounting part to be combined with the drawer can be produced together. The fitting is optionally shaped with the back plate in subsequent processing steps. In this way, the warehousing, manufacture and assembly of the supplementary mounting parts are eliminated, and the parts of the mounting structure can be reasonably manufactured together with the drawer part in each case without additional working steps. In this way, the whole manufacturing process of the drawer becomes extremely simple and rational continuous manufacture of the drawer becomes possible.

In the present invention, at least two side-by-side, side-by-side trimmed tabs of the first drawer portion may be formed at relative intervals. The stop flap works through the opening in the second withdrawal portion and partially works behind, according to the rotational offset caused thereby.

If this mounting structure is formed as a combination of insertion and rotation, the invention is carried out with little manipulation, by a defined connection insertion of the withdrawal parts facing all sides and rotation with respect to each other. It

In a preferred embodiment of the invention, the stop is provided with a joint and a free end each time. The free end is substantially parallel to the side surface of the first withdrawal portion. The joining channel then forms one stop on the edge which borders the opening of the second withdrawal part. Due to this stop, the rotational movement is restricted during the mutual connection of the drawer parts. Thus, these stoppers cooperating with the opening of the second drawer part lock both relative positions in the combined drawer part.

Moreover, it is advantageous to arrange on the side plates of the first drawer part two stop flaps which are arranged perpendicularly to one another. In this case, the stoppers of both stop flaps are arranged so as to be on one common perpendicular line.

At the same time, the edge of the opening in the second device part is also arranged on one vertical line, so that the rail in the assembled state is mounted exactly horizontally so that the coupling parts do not rock in this position.

The mutual distance between the stop knobs allows the transmission of a relatively large rotational moment to the back plate of the rail and vice versa so that the stop knobs do not twist when the combination of insertion and rotation is made. To

Besides, as a preferred embodiment of the present invention, it is advantageous to use a rail made of a hollow profile. In this case, the openings are in each case punched out from the side plates which are attached to the side edges of the back plate. The advantage of this configuration is that the free end of the stop flap can grab the inner wall from the rear, since the joint path of the stop flap must be relatively short beforehand, ie only in the length of the side plate thickness.

This structural criterion minimizes the moment acting on the stop and ultimately protects the mounting structure from unwanted deformation.

Another advantage of forming the rail as a hollow profile is that it serves as a decoration for the mounting structure with the side plates on the outside of the hollow profile facing each other, so that the mounting structure cannot be seen from the outside in the assembled state, whereby the mounting part is not visible. It should not interfere with the desirable appearance of the drawer.

[0021]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The mounting structure as shown in FIGS. 1 to 6 is
It is generally composed of two types of coupling parts. That is to say one of the parts which can be inserted into the other type of part each time, in which case one part in the form of a stop flap 6, 7 is joined to the back plate as if glued. It is a thing. The second type of component is the side plate 15 of the rail 3.
Are formed as openings 13 and 14.

In the example shown here of the stop flaps 6, 7 and the openings 13, 14 on the back plate 2 and the rail 3, the stop flaps 6, 7 are provided on the rail 3 in exactly the same way, Opening 1
It is also possible to provide 3,14. 6 or 7
, The rail 3 and one of the openings 13 or 14 of the back plate 2 can be exchanged.

On the contrary, the essence of the invention is that the arrangements and shapes of the stop flaps 6 and 7 and the openings 13 and 14 are sequentially adjusted. At this time, the opening 13 is attached to the stop flap 6, and the opening 14 cooperates with the stop flap 7. The stop flaps 6, 7 and the openings 13, 14 cooperate to form a kind of insertion and rotation connection. This connection is formed like a slide lock in the shape of this embodiment.

As shown in FIGS. 1 and 2, the back plate 2 of the drawer has a right-angled shape. In this case, the back plate forms on each side on its same side a curved side edge 5, 5'and upper and lower edges 4, 4 '. The back plate 2 can be formed of a metal plate, for example, a thin steel plate or an aluminum plate, as shown in this embodiment, or can be formed of a synthetic resin material by injection molding. The rail 3 is always manufactured from the same material.

At the side edge 5, two stop flaps 6,
7 are stamped from thin metal sheets at intervals. The stop flap is bent from the plane of the side edge 5 toward the front (outer side), and at this time, the free ends of the stop flaps 6 and 7 become shallower in angle again, and are parallel to the plane of the side edge 5. Are formed at intervals. The distance between the free ends of the stoppers 6, 7 is the joint path 8,
It is determined by the length of 9 and substantially matches the plate thickness of the side plate 15 of the rail 3 as described later.

It is important that the free ends of the stop flap 6 and the stop flap 7 are oriented in opposite directions. The opposite orientation of the stop flaps 6 and 7 means that when the back plate 2 rotates about a single horizontal axis that penetrates between the two stop flaps 6 and 7, the rotation direction is the same circumferential direction. To the junction 8, 9
Is what is directed.

As shown in particular in FIG. 3, both stop flaps 6, 7 are formed in such a way that the connecting passages 8, 9 always lie vertically and exactly on one common perpendicular 10. At this time, the joint passages 8 and 9 are provided in the direction of the arrow 20 so that one of the pair of the rails 3 is formed to form the stopper 1 in the vertical direction.
1, 12 are formed.

The free ends of the stop flaps 6 and 7 are connected to the joint paths 8 and 9.
It is formed in a fan shape from the outside. In this case, as shown in FIG. 5, the front end 18 can always be angled outwards. This angle-reduced end 18 then acts as a plug-in gradient when the lead-in sections are rotationally introduced when the two lead-out sections 2, 3 are inserted through the openings 13, 14 arranged in the rail. work.

However, the profile of the fan-shaped stop flaps 6, 7 can be right-angled or any other conceivable shape. However, so that the stop flaps 6, 7 can be inserted through the opening in a linear insertion movement, in this case the opening 1
It is important that the contour shapes of 3 and 14 are extremely large.

As shown in FIG. 6, the openings 13 and 14 are punched from the side plate 15 of the rail 3 according to the arrangement and shape of the stop flaps 6 and 7 on the back plate 2.

Regarding the shapes of the openings 13 and 14, the opening 1
The edges 16, 17 which limit the rotational movements 3, 14 of the rotary movement in the direction of the arrow 20 are always arranged on the common perpendicular 10 ', and the openings 13, 14 extend from these edges 4'in the opposite direction of the arrow 20. Being extended is important.

Thus, as mentioned above, the stop flaps 6, 7 can be inserted through the openings 16, 17 and the parts 2, 2 until the stoppers 11, 12 are in close contact with the edges 16, 17.
The side plates 15 are opened by the corresponding twists of 3
You will surely grab from within the range of. Junction 8,
Since the length of 9 corresponds somewhat to the material thickness of the side plate 15, the rails on the side plate 15 are the stop bars 6, 7 and the side plate 5 of the back plate 2.
It is firmly fixed between and.

Arranging the stop flaps 6, 7 and the openings 13, 14 as desired allows the rail 3 to be in one line to the back plate 2. Make sure that the rail 2 in this state does not wobble and is safe against deviations in all directions.
The distance between the edges 23 and 24 of the openings 13 and 14 is selected according to the distance between the edges 21 and 22 of the joints 8 and 9, and in the assembled state they fit very closely together.

As shown in FIGS. 1, 2 and 7, the rail 3 was chosen as a hollow profile with a substantially rectangular cross section, but this profile is not necessary for the operation of the mounting structure according to the invention. It is also possible to use sheets of simple cross-section that retain the bending stiffness required by suitable seams and curved lines.

As for the outer shape of the rail 3 as a hollow mold member, since the outer hollow mold member side plate facing the side plate 15 covers the joint portion and makes it invisible from the outside, it is of course possible to obtain the advantage that the completed drawer maintains a preferable appearance. .

In addition to this, the mounting structure has a steel back plate 2
It is also possible to first form the stop flaps 6, 7 only by stamping and bend them when the rail 3 is later mounted in the drawer in the shape described above. Apart from the desired later-time installability, the backboard 2 can therefore also be used for other installation purposes and drawer configurations. At the same time, with such shaping of the backboard, the production of various drawers can be standardized and a reasonable continuous production is possible.

[0037]

In the mounting structure of the present invention, when the first withdrawal portion serves as the inserting means, it can be at least partially inserted into the receiving means formed in the second withdrawing portion corresponding to the inserting means. Thus, the mounting structure is a combination of insertion and rotation.

Therefore, the direction other than this insertion is fixed,
It eliminates the need for a mounting part and the labor for mounting these parts, which is required in the conventional structure for connecting two drawer parts, and makes the drawer manufacturing process simple and rational continuous manufacturing possible.
