Abstract

PURPOSE: To arbitrarily and quickly fix a position, and to improve stability by clamping a hinge section through at least one rotatable clamping eccentric member. CONSTITUTION: A clamping surface is spread by gripping a hinge section 4, to which clamping eccentric members 12 are attached pivotally, from a rear, and eccentric body sections 13 are rotated in the direction of a groove bottom 22 when clamping levers 18 are rotated. Highest clamping force is obtained immediately before the clamping levers 18 reach their closing positions in the eccentric body sections 13 of the clamping eccentric members 12 at that time. Clamping force is decreased slightly at the closing position, and the eccentric body sections 13 are fixed stably to slipping-off, looseness or the like even by vibrations or the frequent openable operation of a door movable fitting. Notches 19 are formed at the free-side end sections of the clamping levers 18, and a blade for a screw driver can be hung to the notches for releasing a fixed state. The notches 19 retain the clamping levers 18 into the hinge section 4 together with projections 21 formed to the hinge section 4.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single shaft type hinge for fixing to a frame molding material, and a hinge portion fixedly fixed to the frame molding material, and a single hinge which can be swiveled around a swivel axis. And a type having an arm.

[0002]

2. Description of the Prior Art Uniaxial hinges of the type mentioned, also called uniaxial bands, are needed to allow as many variations in form as possible when assembling a chest wall member with a frame molding made of aluminum, for example. It Frame moldings often have the added function of receiving a sealing member, for example. In addition, the frame molding is provided laterally with an array of holes, which makes it possible to suspend intermediate bottoms or other chest wall members at different heights. The hinge portion of the uniaxial hinge can be fixed to this hole row.

The frame moldings, called multipurpose moldings, have lock fastening grooves in addition to the grooves for the sealing members, the row of holes or the grooves for the shelf bottom support. The frame molding is laterally fixed to the end faces of the vertical and horizontal wall members or directly to the end faces.

It is also known to slidably guide the hinge portion of a uniaxial hinge into an undercut groove guide in a frame molding and to fix it with a groove block or a clamping block. The undercut groove can be provided on the end surface side of the frame molding material or on the side portion of the frame molding material. Such a fixing of a uniaxial hinge has the disadvantage that the hinge part has weakened cross sections due to the screw holes, which limits the loadability of such a uniaxial hinge.

Another drawback of such a uniaxial hinge is that it requires other loose parts, namely groove blocks and screws, which must be positioned prior to fixing to fix the uniaxial hinge. is there.

Another known uniaxial hinge is simply inserted and screwed into the groove on the unundercut end face of the frame molding. Such a uniaxial hinge has the drawback that the hinge part cannot be fixed at any desired location and in each case can only be fixed according to the hole pattern provided in the groove.

All known single-axis hinges also have the disadvantage in common that they require tools for mounting.

[0008]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a uniaxial hinge which allows easy and quick installation and has high stability.

[0009]

SUMMARY OF THE INVENTION In order to solve the problems of the invention, the hinge portion may be fixed in a biased manner to the frame molding through at least one pivotable clamping eccentric member. Proposed.

[0010]

By using a clamping eccentric which is clamped against the frame profile, the hinge part can be arbitrarily and quickly fixed in a favorable manner on the frame profile. In this case, the hinge portion does not suffer from a reduction in strength due to the reduced cross-sectional area due to the threading through. Furthermore, the corresponding clamping surface on the hinge part can be constructed as short as possible in order to avoid conflicts during the fixing of the cup-shaped member of the hinge arm pivotally mounted on the hinge part.

The clamping eccentric member is preferably pivotally mounted on the hinge part. A loose part is not required to secure the uniaxial hinge in this manner, and the securing device becomes a component of the uniaxial hinge.

In a preferred embodiment, the hinge portion holds the frame molding from behind. Grasping the frame molding from the back makes it possible to enlarge the clamping surface.

According to a further embodiment of the invention, the hinge portion has a guide member for engaging a guide member of the frame molding, the cross-sectional profiles of both guide members being adapted to one another. There is. Such a configuration of the guide member allows a play-free, rotation-inhibited mounting of the uniaxial hinge after fixing the hinge part.

The clamping eccentric member preferably comprises a clamping lever. This clamping member makes it possible to bring the clamping eccentric member into the clamping position without tools. Therefore, the uniaxial hinge can be quickly positioned on the frame molding using the clamping lever and immediately fixed without using a tool.

In a particularly preferred embodiment, the fork elements of the hinge part, which consist of the fork part, are each provided with one clamping eccentric. Placing the two clamping eccentrics at the ends of the hinge part enlarges the base of the clamping surface and allows clamping fixation over the entire length of the hinge part. The expanded base more reliably prevents rotation of the single axis hinge.

The tightening lever may be arranged to be housed in the hinge portion in the tightened state. The arrangement housed in the hinge part has the advantage that the fixing means are not visible from the outside.

According to another embodiment of the present invention, the tightening eccentric member exerts the maximum tightening force immediately before reaching the end position in the closed position. In the closed position itself, the clamping force is slightly reduced compared to the maximum clamping force. In a simple manner, this provides protection against the automatic loosening of the fixing of the uniaxial hinge.

A spring-elastic shaft member is preferably arranged in the radial direction on the pivot axis of the clamping eccentric member. Such a shaft member, for example a slitted clamping sleeve or a spiral clamping sleeve, as compared to a pin made of solid material, compensates for manufacturing errors of the guide member, whereby the mutually adapted hinge sides are provided. Even when the guide member on the frame side has a manufacturing error, the function of the tightening eccentric member is guaranteed.

The hinge-side and frame-side guide members may extend parallel to the end surface of the wall member.

However, the guide member may alternatively be arranged parallel to the side face of the wall member. This has the advantage that the end face of the wall member can be used, for example, to receive a seal molding. When the guide member is arranged laterally, the hinge portion is bent.

Furthermore, in one embodiment of the present invention, the hinge portion is supported by a notch in the frame molding material that is fitted to the protrusion by a protrusion protruding from the hinge portion toward the guide portion on the frame side. .. Such a protrusion can project from the hinge portion in a dovetail shape and engage a notch in the frame molding. In this way, not only the guide member can receive a corresponding lateral force, but the projection can receive a lateral force.

In this case, the frame molding can consist of a hollow molding. The hollow molding supports lateral projections against the swivel axis in two places against lateral forces. In the case of a hollow molding, the projection penetrates the first wall provided with the notch of the hollow molding and another notch or a reception in the second wall parallel to the first wall of the hollow molding. apparatus,
For example, it is supported by a support groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A uniaxial hinge 1 comprises a hinge part 4 and a hinge arm 10 which are connected to each other via a shaft pin 28 which is rotatable about a pivot 26. There is. The hinge part 4 is constructed as a fork part 6 with two fork elements 8 between which the hinge arm 10 is received. The hinge part 4 is supported in the hinge part 4 by means of two tightening eccentric members 12 which are pivotable about a swivel axis 30. By being pressed onto the groove bottom 22 of the dovetail guide via the above, it is tightened in the dovetail guide 24. A foot portion 5 on the side of the hinge portion 4 opposite to the side of the turning center axis 26.
Serves as the hinge-side guide member 14, whereas the groove 20 provided in the frame molding 2 serves as the frame-side guide member 16. The guide member 14 on the hinge side and the guide member 16 on the frame side are formed so that their cross-sectional shapes fit with each other. When the tightening eccentric member 12 is tightened, both guide members 14, 1
6 are crimped to each other, and firmly fix the position of the uniaxial hinge with a high crimping force. The dovetail guide 24 is excellent in having a large tightening surface as shown in FIG.
However, it is also possible to use further shaping grooves which engage one clamping surface from the other from behind.

In the embodiment of FIG. 1, the eccentric body part 13 of the tightening eccentric member 12 is gradually swung towards the groove bottom 22 when the tightening lever 18 is swung towards the hinge part 4. The shape of the eccentric body part 13 of the clamping eccentric member 12 is such that the clamping lever has the highest clamping force in the end position just before reaching its closing position, which clamping force is slightly reduced in the closing position. Is configured. With such a configuration, the uniaxial hinge can be fixed by the tightening eccentric member 12 which is not disengaged or loosened by vibration or frequent opening / closing operations of the door shoji.

As can be seen in FIG. 1, the hinge part 4 has corresponding notches for receiving the clamping eccentric member 12 with the clamping lever 18, so that the clamping lever 18 is hinged in the closed position. It is in a state where it has entered the portion 4. The clamping lever 18 has a notch 19 at its free end, on which the blade of a screwdriver can be hooked in order to unlock the hinge. The notch 19 also serves to cooperate with a protrusion 21 provided on the hinge part 4 to keep the clamping lever 18 locked in the hinge part 4.

As shown in FIGS. 2 and 3, the hinge arm 10 is mounted in the hinge cup 11 of the door shoji 3 through a screw joint 7.

The frame molding material 2 has a web 15 on the wall member 9.
, The web is pushed into the slits in the end face of the wall member 9 and, if necessary, adhered thereto with an adhesive.

FIG. 4 shows a second embodiment, in which the foot 5 extends beyond the entire length of the fork portion 6. The clamping eccentric member 12 is pivotally mounted in this extended part of the foot 5 and bears against the end face of the fork part 6 with the clamping lever 18 in the closed position. The clamping lever 18 has a notch 19 for hooking the blade of a screwdriver in order to facilitate the unlocking of the hinge, as in the embodiment of FIG.

In the embodiment of FIGS. 1-3, the hinge is completely unlocked by pivoting the clamping lever 18 towards the groove bottom, thus moving the hinge in the groove 20 parallel to the groove. You can

FIG. 5 shows a third embodiment. In this case, in order to tighten the tightening eccentric member 12, the tightening lever 18 must be rotated in the direction opposite to that of the above-described embodiments. .. The clamping lever 18 rests on the groove bottom 22 in the closed position.

The clamping eccentric member 12 can be supported in both fork elements 8 by means of a shaft element 32 as a solid pin, for example.

However, it is advantageous to use, as the shaft element 32, a clamping sleeve with slits or a helically designed clamping sleeve. Such a radially elastic construction of the shaft element allows for possible manufacturing errors between the bottom surface of the dovetail groove 22 and the position of the hole for the shaft element, without impairing the function of the clamping eccentric. ,
It is advantageous in that it can be compensated.

FIG. 6 shows a wall member 2 parallel to the end surface of the wall member 9.
It shows yet another embodiment with a frame molding made of a hollow molding having one molding surface 35, 37. The hinge part 4 has one or more projections 36 which are threaded into a notch 38 in the molding surface 35 which is adapted to the cross-section of the projection, and the other end of which is provided in the molding surface 37. The cross-section provided ends in a V-shaped support groove 40.
This embodiment is particularly suitable for supporting high lateral forces. This is because in this case the lateral force is not only supported by the guide members 14, 16,
Protrusion 36 supported in notch 38 and support groove 40
This is because it is additionally supported by.

The frame molding 2 has lateral moldings 42, which serve for mounting further components such as packings.

Basically, it is also possible to fix the hinge part 4 in the lateral molding part of the frame molding material by tightening the eccentric member 12, and in this case, the molding part provided on the end face of the frame molding material. Serves to receive the packing. When the hinge is fixed laterally with respect to the wall member 9, the hinge part 4 is constructed in a bent shape.
