Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a joint fitting for removably joining two furniture members that abut each other at right angles and are to be connected to each other in this range. For tightening, a protruding tightening bolt with a head is mounted: it is rotatably supported in the plane of the other furniture member (in the plane), and one eccentric tightening is carried out in the plane. The fastenings with the metal parts are inserted together with the parts (C) and the forest-like casing is inserted in the following way, i.e. the fastening bolts identified in one furniture part are connected to the recesses and casings on the end side of the other furniture part. At least the tightening is guided into the housing of the other furniture component and/or the ID casing on the side opposite the operating side of the component, and the tightening is carried out by turning the component 1' to the tightening bolt. The clamp is inserted in such a way that the clamp can be brought into functional connection with the component in such a way that it can be drawn into the casing by means of a surface, the clamp being inserted through a cutout on the front side of the casing. Be within reach 9
Further, the tightening head is connected to the shaft portion which has a narrow diameter with a joint surface surrounding the shaft portion of the tightening bolt at an obtuse angle, and the tightening member is connected to the tightening member. This invention relates to a joint fitting that is equipped with an insertion opening for a head.

The joint fittings of the type are according to German Patent Publication No. 1753.
Known by No. 064. In this known joint fitting, the tightening is performed so that the rotation axis of the component is perpendicular to the longitudinal axis of the tightening bolt and slightly relative to the plane of the other furniture component in which the tightening bolt is fixed. It's just keeping a distance. Therefore, tightening involves approaching the component and tightening by turning the component (which makes it difficult to apply the tool). The attachment surrounds the head.

The problem to be solved by the present invention is to solve the problem of the fitting depth of the casing and/or
It is not necessary to increase the height of L yet, and the only thing to tighten is to form the joint fittings so that the part (Rikuchin to O and the tool to apply the tool to part 1) is in the middle. In this case, tightening is performed by forming the metal fittings in such a way that the functional connection 1d between the member and the tightening bolt is not deteriorated as much as possible.

This problem 1 is in the joint regulations of the type mentioned at the beginning, and is solved by the present invention in the following manner. Namely, the tightening is eccentric to the rotation l@ of the member 1d, and the tightening is eccentric to the rotation l@ of the member 1d. For tightening with an insertion side port for the head, use the sleeve with type 1.
(and the tightening is carried out when the rotational axis of the member is rotatably supported at an obtuse angle equal to the angle between the shaft portion of the tightening bolt and the joint surface with respect to the longitudinal axis of the tightening bolt in the casing. The sleeve has a tightening of 1σ.
Surround and grip the head with the inner wall of the second part, and add one more, that is, surround and grip the head so that the sleeve touches the joint surface and a small part of the shaft part of the tightening bolt. This can be solved by doing so.

At that time, the sleeve l is certainly tightened only on one side, but
Even so, the tightening bolt is operatively connected to the head over a large area, and the stroke of the tightening bolt can be converted into a large rotation angle of the member. Therefore, when tightening, a small torque is applied to the member, and when a large tightening force is transmitted to the tightening bolt, the adjustment of the joint fittings is actually considerably simplified. In each rotational position, the tightening of the bolt at the head ensures sufficient self-braking of the member. For tightening, the pivot axis of the member is at an obtuse angle with respect to the longitudinal axis of the tightening bolt, so that it is easily accessible and easy to use with tools. Since the tightening member does not surround or grip the head on both sides, there is no need to increase the depth of fitting of the casing.

The tightening of the casing, which must be as closed as possible to the visible front side, is made easier by the developed shape, which is more advantageous for accommodating the parts, in the following way:
That is, a round casing is constructed of two half-shell bodies, which extend along the diameter of the dividing plane Iσ, and have a snap receiving opening within the range of the dividing plane. and are connected to each other using snap pins, and the tightening is such that one rotation of the member is within the dividing plane.The plastic half-shell body is divided through a film hinge. Advantageously, they are integrally connected to one another at one end of the surface and are manufactured as a plastic injection molding in the hinged open position.

Inside the casing 1 (in order to support the member in a rotational manner, according to the shape of the present invention, the circumference of the ribbon +C is as follows)
It is provided with semi-circular support receptacles for the six guiding webs, which are formed by the casing parts of the shell body, which are in contact with each other. When the shell bodies are combined, they form a cylindrical housing part. In this case, the parts are tightened together by these casing parts of the half-shell body.
In the axial direction (
It is made in such a way that it is firmly held so that it cannot move.

To temporarily fix the tightening bolt inside the casing, do the following: tap the inside of the casing (the inserted tightening bolt should be tightened on the side that is not surrounded by the member). In this case, the casing part that grips the head is used to prevent it from coming out of the casing.The casing part protrudes into the notch of the casing only at the part on the shore. This portion 1d is smaller than the difference between the dimension of the notch perpendicular to the tightening bolt and the maximum diameter of the tightening bolt.

Therefore, the tightening bolt 1 can be inserted into the casing and tightened into the member without being adversely affected by this casing part.

Next, the implementation of the present invention will be explained in detail using the figure box.

Fig. 1 1C Fitting two half shell bodies 21 together
The two casings 20 are completed. However, the tightening members and tightening bolts are removed from this casing assembly. The dividing plane, d, runs along the diameter exactly in the middle. This casing assembly is fitted into a hole provided at the bottom of the partition plate with the notch 22 facing toward the furniture body. For fastening, which will be described later, a support protrusion of the member is inserted into a hole 29' formed when the two half-shell bodies 21 are brought together, and a tool for rotating the member can be inserted through this hole 29'.

FIG. 2 shows one half shell body 21 divided by division 1rn in FIG. This inner hollow surface is provided with grooves 25 and 29 for fitting a member 40 for tightening, and furthermore, grooves 25 and 29 are provided for tightening, which will be described later, by inserting a guide web 41 provided on the outer periphery of the sleeve 49. A deep groove (support housing portion) 28 is provided. However, should the member 40 be rotated when tightening? For this purpose, the deep groove 28 terminates at an end 28', which serves as a stop. This half shell body has three snap pins 31.
, 32, and 33 are provided, and are fitted into snap receiving holes 51, 52, and 53 provided in the other bar funnel body, respectively, to provide a drier function.

FIG. 3 shows the state where the tightening member 40 is inserted into the back of the half shell body shown in FIG. 2 and the tightening bolt 12 is set. In practice, when tightening the bolt, the bayonet opening 47 is directed toward the notch 22 in the casing assembly in order to functionally connect the component. Then the tightening will be done on head 1.
7 is such that the clamp can be inserted into the member beyond the casing part 55.

Next, using FIG. 4, a joint fitting according to the present invention will be disclosed in detail 1.

0, so that the tool can be easily inserted into the tool receptacle 46.

The casing 20 extends to the end face of the partition plate bottom 19 and is provided with a notch 22 (see FIG. 1) within this area into which the tightening bolt 12 is inserted. As shown in FIG. 3, when the member 40 is tightened, the sleeve 491 is tightened, and when the member 400 is at a predetermined rotational position, the tightening bolt 12 is inserted so that the tightening bolt 12 can be introduced into the sleeve 49. It is provided with a notch 47 for insertion.

The cutout 22 in the casing 20 allows the tightening bolt 1 in the casing 20 to be oriented at right angles to its longitudinal axis.
This allows a limited displacement of 2. When the partition plate bottom 19 is slightly raised, the tightening bolt 12 is tightened together with the head 17, and the member 40 is tightened as it is introduced into the inner space of the sleeve 49. 171 heads 17 are inserted over the entire casing section 55. The tightening bolt 12 is inserted into the casing 20, and then the partition plate 19 is pushed down.7.Casing part 5s
Tightening of the RA tightening bolt 12 catches the head 17 so that it can no longer be pulled out. When the tightening member 40 is rotated, the tightening sleeve 49 surrounds and grips the head 17. The center axis 50 of the tightening sleeve 49 is eccentrically offset from the rotation axis 44 of the tightening member 400, and as a result, the tightening is caused by the low movement of the member 40 and the tightening head 17 of the bolt is rotated. It is drawn into the casing 20. Therefore, a large tightening force is generated between the partition plate bottom 19 and the side flap 10, and the tightening force is small compared to the 1 year old 401/7. 12
This is because the tightening stroke in the I direction is converted into a large rotation angle of the member 40.
