Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an adjustment rod fitting for windows, doors or the like, comprising a cover rail, an adjustment rod, supported in a casing fixed to the cover rail. a transmission member, which transmission member engages the adjustment rod guided in the shoe of the casing;
The shoe is of the type having a transmission box with an approximately semicircular cross section and housing extensions located on both sides of the transmission box and each provided with a threaded hole.

[Prior Art] Adjustment rod fittings for windows, doors, etc. have traditionally been mainly used in the Federal Republic of Germany, and have recently been imported into Japan. First, let us give a general explanation of these adjustment rod fittings. Then,
The adjusting rod fitting has a cover rail and an adjusting rod which is supported longitudinally displaceably behind the cover rail. The cover rail has screw holes for fixing screws,
It has a vertical slit through which a locking pin fixed to the adjustment rod passes. Such adjustment rod fittings are attached to the shoji of a window or door, also on the edge surface of the shoji frame that is perpendicular to the shoji plane and faces toward the outer frame. The adjustment rod metal fittings are
It can be attached to one side of the shoji, usually the side opposite the shoji opening axis, but it is useful to attach adjustment rod fittings to multiple sides of the shoji to transmit the movement of the adjustment rod. These adjustment rod fittings can also be connected to each other by special connecting fittings called corner drives. The adjustment rod fitting is usually fitted into a fitting groove formed on the edge surface of the shoji, and the bottom of this fitting groove is also provided with a housing recess for the casing fixed to the cover rail. Inside this casing is a transmission, usually a pinion, which transmits the driving force to the adjusting rod. The operation of the transmission pinion that moves the adjustment rod is performed by an operation grip provided on the inner surface of the shoji frame, and the movement of the adjustment rod causes, for example, the locking pin of the adjustment rod fitting to be fixed to the outer frame. A locking pin can be engaged with or disengaged from a closing fitting, or in the case of a so-called drake window (a window that can move both inward about its horizontal axis and open inward about its vertical axis). The opening axis is switched by the operation.

According to German Patent No. 1750589, the transmission box provided in the casing for accommodating the transmission pinion has a semicircular cross-section so that the adjusting rod fitting can be inserted by narrowly adapting it to the diameter of the pinion. It is known to form The transmission box accommodating portion provided in the frame portion of the shoji or sash frame can be formed from the exposed side using a blind hole drill. In this case, its axis is arranged behind the bottom of the adjustment frame groove so that the transmission box accommodating portion opens toward the adjustment rod groove of the metal fitting groove provided on the prospective surface. The adjusting rod fitting can therefore be inserted into the fitting groove and the transmission box receptacle from the perspective side parallel to the plane of the sash frame or the plane of the sash frame. For operating the adjustment rod fitting, an operating grip is provided which is located on the visible side of the frame part and is supported within the rosette. This operating grip is often connected to the pinion of the adjusting rod fitting via a squared rod. In that case,
This square-shaped bar is located within the blind hole. The fixing of the rosette takes place by screwing two fixing screws into the material of the frame part from the side near the transmission box.

In order to improve the guidance of the adjusting rod through the casing in insertable adjusting rod fittings, according to German Patent Application No. 2039042, a shoe is provided which extends beyond the transmission box in the longitudinal direction of the cover rail. It is being This shoe is accommodated in the adjustment rod groove when the adjustment rod fitting is assembled.

According to German Patent Application No. 2 301 390, it is possible to fix the fixing screw for the rosette in the housing of the adjusting rod on both sides of the transmission box. One rearward-facing casing extension is integrally molded on each shoe. The casing extensions are each provided with a threaded bore. This fixed form is hereinafter referred to as a stable fixed form.
The transmission box receptacle and the housing extension receptacle are manufactured in one operation, preferably by means of a triple drill head.

Furthermore, according to the disclosure of German Patent Application No. 2417101, an insertable adjusting rod fitting is provided with a guide in the shoe, into which the casing attachment part is inserted. Therefore, the operator has the option of fixing the rosette either in a stable fixed manner or by screwing fixing screws into the material of the frame part. For this purpose, the operator must fix the casing extensions, which form their own parts and which may be formed separately from one another or are connected to one another, to the casing or remove them from the casing. There must be. Although it is extremely easy for the operator to work with, it has the disadvantage that the casing attachment must be assembled or removed by the operator himself. If the operator does not have enough casing additions on hand, the selection of options is also limited. Only the transmission box accommodating part is provided in the frame part,
If the casing is provided with a casing extension, the casing extension must be removed afterwards. This is particularly disadvantageous if the frame part is already equipped with a transmission box receptacle as well as a housing extension, and no housing extension is provided. In that case, the production of the window must be postponed until a new casing addition is available.

OBJECT OF THE INVENTION It is an object of the present invention to provide an insertable adjustable rod fitting which allows the rosette to be selectively fixed with or without a stable fixation, and which avoids the above-mentioned disadvantages. It is in.

The configuration of the present invention which solves this problem consists in that, in an adjusting rod fitting of the type mentioned at the outset, the casing attachment part is pivotably supported in the shoe in a fixed position.

The casing extension, which has already been pivotably fastened to the shoe on the production side, can be pivoted to a rearward position away from the cover rail, in which position the rosette can be fixed in a stable manner. can. If you want to fix the rosette without using the stable fixing method, turn the casing attachment part so that it extends almost parallel to the longitudinal direction of the cover rail, and place it within the range of the adjustment rod groove when the adjustment rod bracket is assembled. position. By swiveling the casing attachment part to the shoe in a non-removable manner at the production site in this way, the additional effort of replacing the casing can be eliminated in various applications, and the casing attachment part is always present. This adjustment can be carried out without having to wait for the availability of the casing extension beforehand, even if the frame part is provided with only a transmission box receptacle or with both a transmission box receptacle and a casing extension receptacle. Rod metal fittings can be used.

In an advantageous embodiment of the invention, the casing extension comprises a bearing with a pivot and an eye with the threaded hole, the bearing being arranged in a recess in the shoe. and the pivot shaft is supported in a side wall formed in the shoe by the cutout.

As a result, the pivot axis is mounted between the adjusting rod and the rear side of the shoe, which is located parallel to it, so that the casing extension lies within the cross-sectional area of the shoe in the swing-away state. Moreover, a compact shape is provided.

It is customary for the casing to be formed in two parts with a dividing plane located in the longitudinal direction of the cover rail and to be manufactured from zinc die casting. Since the housing extension is likewise produced from zinc die-casting, it is advantageous for the bearing pin forming the pivot to be integrally molded onto the bearing. Before assembling the casing halves, the casing extension is placed between them and the bearing pin is inserted into the hole in the side wall of the shoe during assembly of the casing halves, thereby securing both casing halves. Additional work on the housing extensions can be omitted if the housing extensions are permanently fixed to one another after riveting the halves.

It is particularly advantageous if the distance between the pivot axis of the housing addition and a central transverse plane passing through the housing is small compared to the distance between this central transverse plane and the threaded hole axis of the eye. In this way, the casing attachment part, in the upright state, is located at an angle with respect to the central transverse plane of the casing, that is, with respect to a plane perpendicular to the longitudinal direction and the width direction of the cover rail. If only the transmission position box accommodating part is provided in the frame part, in other words, if the rosette does not need to be fixed with screws in a stable fixing manner, when inserting the adjustment rod fitting into the fitting groove, the casing attachment part should be The adjustment rod collides with the bottom of the groove and is automatically rotated to the separation rotation position because its position is inclined. It is advantageous for the operator to leave the casing extension in the upright position at the production site, since no additional adjustment of the casing extension is necessary, regardless of the desired fastening type of the rosette.

In order to move the point of impact of the casing extension as far as possible from the pivot axis when the casing extension hits the bottom of the adjustment mechanism, the casing extension is tilted with respect to the shoe with it raised towards the transmission box. It is effective to provide the eye with a sloped surface that

When the adjusting rod bracket is assembled when the rosette is fixed in a stable fixing format, the casing attachment part that has turned away from the rod is attached to the adjusting rod, so that the ease of movement of the adjusting rod is not impaired. It is advantageous to provide the side walls of the adjustment rod with an extension wall having a large height compared to the thickness of the adjustment rod, in which case:
Make the length of the eye equal to the thickness of the shoe. In this way, in the state of turning away, the eye is in contact with the end face of the extension wall and is separated from the adjustment rod.

In order to maintain the position of the casing extension, which has been previously set up on the production side, the casing extension must be made somewhat difficult to pivot. This difficulty in pivoting is achieved in particular by providing the bearing with a braking engagement that acts on the side wall of the shoe. This brake engagement is formed, for example, by an integrally molded web having a triangular cross section, with its pointed end touching the side wall.

Next, the present invention will be specifically explained with reference to the illustrated embodiments.

The adjustment rod fitting consists of a cover rail 1, an adjustment rod 2 movably supported behind it, and a casing 3 fixed in place on the cover rail 1. This casing 3 made of zinc die-casting is
The adjusting rod 2 is guided in the shoe 4, and a transmission box 5 with a semicircular cross section is connected to the shoe 4. A pinion 6 is mounted which serves as a member. This pinion 6
has a square hole 7 which meshes with the adjustment rod 2 and is connected to a square pin of a rosette (not shown). On each side of the transmission box 5, a housing extension 8 is arranged on the shoe 4. Each housing extension 8 consists of a bearing 9 and an eye 10 with a threaded bore 11.
The length of the eye 10 corresponds to the thickness of the shoe 4. The support portion 9 is formed with a relatively small thickness so that the shoe 4
It is arranged in the notch 12 of. This cutout 12 is delimited by a side wall 13 of the shoe 4 and a stopper wall 14. The side wall 13 is provided with a hole 15 into which a bearing pin integrally formed on both sides of the bearing part 9 of the casing extension part 8 is inserted;
As a result, the casing extension 8, which is also made of a zinc die-cast product, is pivotably and irreleasably supported on the shoe 4. The casing attachment part 8 is
It is supported so as to be pivotable about a pivot axis 17 defined by the cooperation of the support pin 16 and the hole 15.
In that case, the pivot axis 17 of the casing addition part 8
and the central transverse plane 18 passing through the casing 3, the interval between the central transverse plane 18 and the threaded hole axis 1 of the eye 10
It is small compared to the distance with 9. This dimension of the spacing causes the casing extension 8 to lie obliquely relative to the central transverse plane 18 in the raised position in such a way that its free end 20 lies far from the central transverse plane 18 . The eye 10 is provided with an inclined surface 21 extending from its free end 20, and this inclined surface 21 extends in an inclined direction toward the shoe 4 at the raised position of the casing attachment part 8.

An extension wall 22 continues from each side wall 13 of the shoe 4, and the height of the extension wall 22 is slightly larger than the thickness of the adjustment rod 2 when measured perpendicularly to the width side of the cover rail 1. big. The support portion 9 of the casing attachment portion 8 is provided with a stopper protrusion 23 on a surface facing the stopper end wall 14 and a brake engagement portion 24 on a surface perpendicular to this surface. The portion 24 has a triangular cross section and is crimped to the side wall 13 of the shoe 4 at its tip.

The illustrated adjustment rod fitting is the projected surface 25 of the frame portion 26.
It is assembled into the metal fitting groove 27 provided in the. This metal rod 27 consists of a cover rail groove 28 and an adjustment rod groove 29. The cover rail groove 28 serves to accommodate the cover rail 1 , and the adjustment mechanism 29 serves to accommodate the adjustment rod 2 and the shoe 4 of the housing 3 . A transmission box accommodating portion 31 opened in the groove bottom 30 of the adjustment rod groove 29 accommodates the casing 3 of the adjustment rod fitting.
transmission box 5.

Both types of fixation of the rosette are shown in the drawings. Above the central transverse plane 18, the case where the casing attachment part 8 is mounted stably fixed in the form of a rosette is shown.
A case is also shown in which the casing attachment part is attached below the central transverse plane 18 in a fixing manner that does not depend on the stable fixing of the rosette.

If the operator wishes to mount the rosette to be installed in the visible part of the frame part 26 in a stable and fixed manner, the transmission box receptacle 31 and the casing extension receptacle 3 are specially drilled by means of a triple drill head.
2 are formed so as to open to the groove bottoms 30 from the visible side of the frame portion 26, respectively.

On the manufacturing side, the casing attachment part 8 is placed in an upright position and shipped, but this upright position is due to the fact that the tip of the brake engagement part 24 of the support part 9 is crimped to the side wall 13 of the shoe 4. It is then maintained. In this state, the stopper projection 23 is in contact with the stopper end wall 14 of the shoe 4. The free end 20 of the housing extension 8 is therefore far away from the central transverse plane 18 compared to the pivot axis 17 . When inserting the adjusting rod in a plane parallel to the plane of the sliding door, the transmission box 5 reaches into the transmission box receptacle 31 and the housing extension 8 into the housing extension receptacle 32. Next, the adjusting rod fitting is fixed in the fitting groove 27 with the screw 33.

No additional work is required to secure the rosette of the operating grip on the exposed side of the shoji. After all, the transmission box housing section 3
This is because the pin with the square portion of the operating grip can be inserted into the square hole of the pinion 6 through the hole for manufacturing. The fixing screw for the rosette is inserted through the hole for the production of the casing extension receptacle 32 and directly into the casing extension 8.
is screwed into a threaded hole 11, thereby providing a stable fixing type of fixation.

If a stable fixation is not desired, only the transmission box receptacle 31 is manufactured. That is, the casing attachment part housing part is omitted. When the adjusting rod fitting is inserted, the transmission box 5 reaches into the transmission box receptacle 31 and the inclined housing extension 8 impinges with its free end 20 against the groove bottom 30 of the adjusting rod groove 29. The collision point of the free end 20 with the groove bottom 30 is far away from the central horizontal plane 18 compared to the pivot axis 17.
When the adjustment rod fitting is further pushed in, the casing attachment part 8 turns away from the raised position around the rotation axis 17, and the adjustment rod structure 2
Reach the 9 range. When the adjustment rod fitting is attached, the casing attachment part 8 is in the separated rotation position and the shoe 4
extending in the longitudinal direction. In this case, the eye 10 rests against the end face of the extension wall 22, so that it does not have any negative effect on the adjustment rod 2. In this way,
The casing extension 8 is arranged in the area of the adjustment rod groove 29 .

Since the casing attachment part, which is placed in an upright position on the manufacturing side, is pivotably supported on the shoe 4 in this way, it is easy for the worker to assemble the adjustment rod fitting, and this makes it easier for the operator to assemble the adjustment rod fitting. Errors on the installation work side are avoided.
