Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an adjustment rod fitting for windows, doors, etc., which comprises a cover rail and an adjustment rod supported movably in the longitudinal direction in the background thereof. The rods are releasably fixed to each other at a predetermined reference position by a temporary fixing member, and the temporary fixing member passes through the adjustment rod and is sheared when the adjustment rod fitting is first operated. Further, a screw guide member is fixed to the cover rail, and the screw guide member is of a type that passes through an elongated hole formed in the adjustment rod.

Adjustment rod fittings for windows, doors, etc. have traditionally been mainly used in the Federal Republic of Doors, and have recently begun to be imported into Japan. First, let us explain the adjustment rod fittings in general.
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 window or door shoji, also on the edge of the shoji frame, which is perpendicular to the shoji plane and faces the outer frame. The adjustment rod fittings can be attached to one side of the shoji, usually the side opposite the shoji opening axis, but it is also possible to attach the adjustment rod fittings to multiple sides of the shoji to control the movement of the adjustment rod. These adjusting rod fittings can also be connected to each other by means of special connecting fittings called corner drives which serve for transmission. 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 member, usually a pinion, that drives the adjustment rod. The drive pinion that moves the adjustment rod is operated by an operation knob 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.

By the way, in the first-mentioned type of adjustment rod fitting described in German Patent Application No. 2313690, for example, the adjustment rod is temporarily fixed at a predetermined position with respect to the cover rail. It is easy to assemble, especially when the adjustment rod is connected to another metal fitting unit, or when the adjustment rod and cover rail must be cut together to match the size of the shoji. Installation can be carried out. In this case, a plastic pin is used as a temporary fixing member for fixing the position, and after the cover rail and adjustment rod are aligned with the desired reference position, the plastic pin is inserted into the cover rail so that they overlap each other vertically at this reference position. and is pushed into the hole formed in the adjustment rod. After attaching the entire fitting to the window, by operating the adjustment rod using the operating knob,
Temporary relative position fixation is easily released. By moving the adjustment rod, the plastic pin is sheared off between the adjustment rod and the cover rail. However, the use of plastic pins as temporary fixing elements requires relatively high costs. For example, one additional hole must be formed in each of the cover rail and the adjustment rod, and the plastic pins must be manufactured separately. In particular, plastic pressing requires high costs. This is because the plastic pin must be fitted and fixed in the hole to prevent it from being pulled out during transportation or installation of the adjustment rod fitting. Since adjustment rod fittings are mass-produced items, additional pushing equipment is required, in particular the process of fitting the end of the plastic pin into the first hole is difficult, and it is difficult to fit both holes accurately. must match. In adjusting rod fittings, in order to reliably guide the fixing screw of the cover rail, a screw guide member is usually fixed to the cover rail with rivets, and this screw guide member is attached to the cover rail when the adjusting rod fitting is attached. supported by the bottom of the metal groove,
This prevents the fixing screw from tilting when strong loads are applied in the longitudinal plane of the cover rail.

However, the object of the invention is to improve an adjustment rod fitting of the type mentioned at the outset, so that no additional material is required for the temporary fixing member, and no additional steps are required for its installation. It is to do so.

In order to achieve this objective, the configuration of the present invention includes:
The temporary fixing element is formed by at least one web formed integrally on the screw guide element, which web is arranged in the widening of the elongated hole of the adjustment rod.

Therefore, the existing screw guide member, which is fixed to the cover rail and passes through the elongated hole of the adjustment rod, is provided with the additional function of temporary fixation. In this case, the web is made of the same material as the screw guide. That is, when the screw guide member is a cast product, it is integrally cast, and when it is a press-formed product, it is integrally press-formed. The web projects into the enlarged part of the elongated hole of the adjustment rod and cooperates with this enlarged part to effect temporary fixation. Since the web is formed together during the production of the screw guide and the widening is formed at the same time by the punching tool required for forming the elongated hole, additional material for temporary fixing is also required. Furthermore, no additional parts such as plastic pins are required, no additional machining steps are required, and in particular no additional costs are required for the attachment of temporary fixing elements. Furthermore,
The web acting as a temporary fixing element does not have to be pushed into the enlarged part. This is because the web is formed integrally with the screw guide and cannot fall off.

In an advantageous embodiment of the invention, the length of the widening, viewed in the longitudinal direction of the slot, is greater than the width of the web. In this case, the assembly of the adjusting rod and the cover rail is no longer complicated by temporary fixing members. If the adjustment rod is provided with fine adjustment devices, for example teeth, the play of the web in the widening is at least half the pitch of the teeth. This allows accurate connection to the metal fitting unit. Of course, you can also make the play many times the pitch of the teeth.

In order to ensure that the adjusting rods are evenly loaded when shearing the webs, the webs are arranged on both sides of the screw guide and engage in enlargements formed on both longitudinal edges of the elongated holes. It is advantageous to match.

In order to ensure that the web is sheared at the desired point during the first actuation of the adjustment rod by means of the actuating knob, and to prevent the actuating force from becoming excessively large, the web has at least one undercut. It is recommended that you have one.

To specifically explain the configuration of the present invention with reference to the drawings, the cover rail 1 of the adjustment rod fitting and the adjustment rod 2 supported so as to be movable in the longitudinal direction behind the cover rail 1 are comprised of a screw guide member 3 which is a pressure cast product. are connected by. That is, the screw guide member 3 is provided with a rivet attachment part 4 on one side, which passes through a hole 5 in the cover rail 1 and is riveted to the cover rail 1, and has a flange 6 on the other side. and is engaged with the back surface 7 of the adjustment rod 2. The base body 8 of the screw guide member 3 passes through the elongated hole 9 of the adjusting rod 2, and in particular the cover rail 1
It also has the function of guiding the adjusting rod 2 when moving the adjusting rod 2 in the longitudinal direction.

In order to temporarily fix the adjustment rod 2 to the cover rail 1 at a predetermined reference position, e.g. the center position, the screw guide member 3 is provided with two webs 1 on both sides thereof.
0, and these webs 10 are formed integrally with the base body 8. The web 10 has an undercut 11 so that the cross section of the web 10 is smallest at the transition to the base body 8. The web 10 engages in the enlarged part 12 of the elongated hole 9. In this case, the length l of the enlarged part 12 is equal to the width s of the web 10 plus the tooth pitch of the rack part 13 of the adjusting rod 2. The rack 13 serves for connection to a not shown hardware unit. In this way, the adjustment rod 2 and the cover rail 1 are removably fixed in position with some play.
This play allows the teeth 14 of the rack portion 13 to be reliably engaged with the corresponding teeth of the metal fittings unit when the metal fittings units are connected.

After installing the adjusting rod fitting, for example, in a groove of a window sash and optionally connecting the fitting unit, the adjusting rod 2 is operated by the operating knob, thereby causing the adjusting rod 2 to be moved in the longitudinal direction with respect to the cover rail 1. . In this case, the web 10 hits the partition edge 15 of the enlarged part 12, and when the force applied to the operating knob is increased, the web 10 hits the undercut part 11.
It is sheared at As a result, the temporary fixation is released or released, and the adjustment rod fitting can be operated normally.

As described above, according to the present invention, the web 10 is integrally formed with the screw guide member 3 and protrudes into the enlarged portion 12 of the elongated hole 9 of the cover rail 2.
No additional material costs or additional assembly costs are required for temporary fixing.
