Latest Firma Richard Heinze Patents:
The continuous adjustment of the hinge arm in the guide is preferably effected in the manner that at least one toothing, for instance a toothing which extends in the longitudinal direction of the hinge arm is provided on the hinge arm and engages with a first adjustment member arranged in the first hinge part, for instance in the inner part of said first hinge part, namely for example with a gear or pinion which is rotatably supported in the first hinge part.
In accordance with a further development, the hinge arm in the first hinge part is adjustable in the direction of the hinge pin or pins, so that an adjustment of the hinge arm is possible in three directions in space, i.e. perpendicular to the surface of the first cabinet part, parallel to the surface of the first cabinet part, and at the same time perpendicular to the axis of swing of the hinge, and in the direction parallel to the surface of the first cabinet part and in the direction of the axes of swing of the hinge. In this embodiment, the inner part of the first hinge part preferably consists of a base body and of a slide which then is adjustable relative to the base body in the direction of the third axis in space, i.e. in the direction of the axis of swing of the hinge.
By means of the invention there is created a rapidly-mounted hinge which is of simple construction, can be worked with the equipment already existing at the furniture manufacturer's, which furthermore permits the technically unskilled final consumer to effect a rapid and reliable assembling of the cabinet parts (pivoting of the cabinet door to the cabinet body), and which furthermore makes possible in just as simple as reliable a manner the adjusting of the cabinet door in the said axes in space. In the same manner, the hinge of the invention permits a simple and uncomplicated removal (for instance, upon moving) of a cabinet door from a cabinet body. The hinge is functionally and aesthetically attractive in appearance, protruding and visible parts being avoided to the greatest extent possible. The hinge of the invention operates without disturbance or maintenance, even in case of heavy duty over a long period of time.
FIGS. 4 and 5 are a top view of the first hinge part and a section along the line I--I respectively;
In FIGS. 1 to 7, 1 is a cabinet body or cabinet side wall and 2 is a rabbetted cabinet door which is pivoted to the cabinet body 1 by the hinge in accordance with the invention. The hinge, in the embodiment shown in FIGS. 1 to 7, consists of an adjustment-body or slide 3 which forms the inner part of the first hinge part and is held for adjustment or displacement, in a recess or first opening of a substantially sleeve-shaped intermediate body 5 or anchoring part of the first hinge part in the direction perpendicular to the surface of the cabinet body 1 or or the axial direction of the anchoring part 5.
The hinge shown in FIGS. 1 to 7 consists furthermore of a second hinge part 8 which is formed essentially of a plate 9 of partially circular or semi-circular shape which is provided with knuckles 11 and 12 formed on the side facing away from the circular surface and serving to support the sole hinge pin 10, the knuckles being such a distance from each other that they can receive between them the end 13, rolled together to form a hinge knuckle, of a tang-shaped hinge arm 14 which is then pivoted by the hinge pin 10 to the hinge part 8. For fastening to the cabinet door 2 there is furthermore provided on the plate 9 on the side opposite the knuckles 11 and 12 a wall section 15 which extends perpendicular to the surface sides of the plate 9 and has a bore 16 for a fastening screw 17. The arranging or fastening of the hinge part 8 on the cabinet door is effected in a recess 18 which is open towards the front side and is provided in part, also in the rabbet 19 of the cabinet door and continues in the rest of the cabinet door. The hinge part 8 is pushed laterally into the recess 18 in such a manner that the plate 9 comes to lie in the part of the recess 18 within the edge 19 while the wall section 15 is arranged in the continuation of the recess 18 on the inner edge 20 of the rabbet and is held fast by screwing the fastening screw 17 into the material of the cabinet door.
The adjustment member 25 is provided at one end with a toothing 26 and on the other end with a section 27 of reduced cross section of circular-cylinder shape and it is furthermore provided on this end with a slot 28 for a screwdriver, not shown. The central section 29 of the adjustment member 25, namely the section lying between the section 27 and the toothing 26, is also of a circular cylindrical cross section, the diameter of the central section 29 being equal to or somewhat greater than the maximum diameter of the toothing 26.
The tang-shaped hinge arm 14 is provided on one longitudinal edge with a toothing 30 which, after the adjustment member 26 has been inserted into the borehole 24 and the hinge arm pushed into the opening 23, cooperates with the toothing 26 so that by turning the adjustment member 25 the tang-shaped hinge arm can be displaced via the toothings 26 and 30 within the opening 23 in the longitudinal direction of said opening. Since the diameter of the central section 29 is equal to or greater than the maximum diameter of the toothing 26, the adjustment member 25, after the introduction of the hinge arm 14 into the opening 23, rests via its central section 29 in the region of the transition between said section and the toothing 26 on the hinge arm 14 in the region of the toothing 30 so that, in this way, at the same time the adjustment member 25 is secured against falling out of the borehole 24 in the direction opposite that of the arrow A. The adjustment member 3 furthermore has a threaded borehole 31 for a screw 32, this threaded borehole opening into the recess 23, so that by screwing the screw 32 into the threaded borehole 31 the hinge arm 14 can be clamped fast in the recess 23. The screw 32 is provided with an extension or lengthening 33 of reduced cross section, this extension 33, after the screwing of the screw 32 into the threaded borehole 31 and before the hinge arm 14 has been clamped fast in the opening 23, extending through a slot 34 in the hinge arm, as a result of which the maximum displacement of the hinge arm 14 within the recess 23 is limited to the length of said slot 34 which extends in the longitudinal direction of the hinge arm 14, so that the undesired falling of the hinge arm 14 out of the recess 23 is prevented.
The adjustable displacement of the adjustment body 3 on the anchoring part 5 is effected by means of an adjustment screw 35 which is developed as a grub screw and lies in semicircular recesses 36 and 37 of the adjustment body 3 and the anchoring part 5 respectively. The semicircular recesses 36 and 37, which together form a closed circular recess, are provided in each case on one surface of the recess 7 of circular segment shape and the shoulder 6 of circular segment shape respectively, the recess 36 having a thread which cooperates with the thread of the adjustment screw 35. The recess 37 does not have a thread but does have, approximately in the center, a web 38 which extends transverse to the longitudinal axis of the recess and engages in an annular groove 39 approximately in the center of the adjustment screw 35 and holds said adjustment screw immovable in axial direction relative to the anchoring part 5. By turning the adjustment screw 35 which is provided for this purpose with a slot 40 at one end for a screwdriver, the adjustment body 3 can be pushed into the recess or opening 4 of the anchoring part 5, in order to compensate for manufacturing tolerances, perpendicular to the surface of the cabinet body 1. Since the thread of the adjustment screw 35 engages into the thread of the semicircular recess 36 and the web 38 at the same time lies in the annular groove 39, undesired displacement of the adjustment body 3 relative to the anchoring part 5 is not possible without turning the adjustment screw 35.
The assembling of the hinge parts is effected aproximately in the sequence that, first of all, the adjustment screw 35 is placed into the recess 37, and thereupon the adjustment body 3 is introduced, with rotation of the adjustment screw 35, into the opening 4 of the anchoring part 5. The adjustment member is now pushed into the borehole 24 in the direction indicated by the arrow A of FIG. 1, with the slot 28 at the front. Thereupon, the hinge arm 14 is pushed through a lateral opening 41 of the anchoring part 5 into the recess 23 of the adjustment body 3 until the toothing 26 of the adjustment member 25 comes into engagement with the toothing 30 of the hinge arm 14, as shown in FIG. 6. Further pushing of the hinge arm 14 into the opening 23 in the direction indicated by the arrow B of FIG. 6 is then effected by turning the setting member 35, i.e., in the case of the showing of FIG. 6, by turning the setting member in counterclockwise direction. As soon as the slot 34 of the hinge arm 14 is within the region of the threaded borehole 31, the screw 32 can be screwed into said threaded borehole so that the shoulder 33 of this screw engages into the slot 34 and the parts then have, for instance, the position with respect to each other which is shown in FIG. 6. By further turning the setting member 25 in counterclockwise direction, the hinge arm 14 is pulled completely into the recess 23, the end position being reached when the shoulder 33 lies against the other end of the slot 34, as shown in FIG. 7. By turning the setting member 25 in clockwise direction, the hinge arm 14 can be pushed back in the direction indicated by the arrow C into the position shown in FIG. 6.
The hinge shown in FIGS. 1 to 7 permits a continuous displacement of the hinge arm 14 and thus also of the cabinet door 2 relative to the cabinet body 1 in two directions in space, namely in a direction perpendicular to the surface sides of the cabinet body 1 by means of the adjustment screw 35 and in the direction parallel to the surface sides of the cabinet body 1 by means of the adjustment member 25, the screw 32 being first of all slightly loosened for the latter adjustment so that its threaded end no longer rests firmly against the hinge arm, and then, after the adjustment, being again tightened and pressed against the hinge arm 14. For the stopping action of the hinge arm 14 produced by the screw 32 within the opening 23 it is advisable to provide the screw 32 at its threaded end with a frustoconically-shaped section which then passes into the shoulder 33 and by means of which the screw 32 after the tightening thereof rests firmly against the edge of the slot 34.
In the embodiment shown in FIGS. 8 to 12 for pivoting the rabbetted cabinet door 2 to the cabinet body 1, the hinge consists of a first hinge part which is formed from a base body 103 which forms the inner part of the first hinge part and a slide 104 held displaceably in the directiion of the double arrow D on the base body 103. The base body 103 is supported for adjustment or displacement together with the slide 104 in a second opening 105 of the anchoring part 106--in this case also of sleeve form--in the direction indicated by the double arrow E, i.e. in the direction perpendicular to the surface of the side wall 1 of the cabinet. The holding of the base body 103 in a non-turnable manner in the opening 105 of the anchoring part 106 is effected in the same way as has been described for the adjustment body 3 of FIGS. 1 to 7, namely with the aid of a shoulder 107 having the shape of a circular segment which extends into the opening 105 and engages into a segment-shaped recess 108 of the base body 103.
In order to obtain as continuous as possible a displacement of the slide 104 relative to the base body 103, there is also provided, in the case of the hinge shown in FIGS. 8 to 12, a setting member 139 which consists essentially of a cylinder part 140 with head piece 141 formed thereon, the cylinder part 140 being provided approximately at its center with a cam body 142 whose peripheral surface in the circumferential direction of the cylinder part is at a varying distance from the center axis of said part. By its end which faces away from the head piece 141 the cylinder part extends into a supporting borehole 143 while the section of the cylinder part lying between the cam body 142 and the head piece 141 is guided in slot 135. The head piece 141 is accessible on the surface side of the base body facing away from the recess 127.
The fastening of the cabinet door 2, which has been premounted with the side hinge part 109 and the hinge arm 115, on the cabinet which has been premounted with the first hinge part (anchoring part 106, base body 103 and slide 104), is then effected in the manner that the free end of the hinge arm 115 is introduced in the manner described above through the recess 126 and the slot 124 into the slot 125. The screw 134 is now inserted through the slot 135, the borehole 136 and the slot 138 of the hinge arm 115 and screwed by means of its threaded end into the threaded borehole 137 of the slide 104, said threaded borehole 137 being located on that side of the inner part of the first hinge part formed by the slide 104 and base body 103 which (side) is no longer visible after the fastening of the anchoring part 106 in the borehole 42.
FIGS. 13 to 19 shows an embodiment of the hinge of the invention which differs from the embodiment of FIGS. 8 to 12 essentially by the fact that an adjustment member for displacing the slide 155 in the direction of the double arrow D, i.e. in the direction of the hinge pivot pin relative to the base body 156 is omitted and instead of it there is provided in the slide 155 an adjustment member 157 by which a continuous sensitive displacement of the hinge arm 158 in the direction of the arrow F, i.e. in the lengthwise direction of the hinge arm relative to the base body 156, is possible. The base body 156 is held, together with the slide 155, in the same manner as the base body 103, in a recess 105 of the anchoring part 106 adjustable by means of the adjustment screw 35 in the direction perpendicular to the surface sides of the cabinet wall 1, i.e. in the direction corresponding to the part E and in the direction perpendicular to the arrow F.
The base body 156 is surrounded, at least in part, i.e. in its place-shaped part 156', on both sides of the slide 155 which for this purpose has two parallel wall sections 159 and 160 which lie parallel to the surface side of the cabinet wall 1 and are connected on one side by a transverse wall 161, this transverse wall extending in the direction of the double-arrow E and having a continuous slot 162 for the introduction of the hinge arm 158 and of the end of the hinge arm facing away from the hinge knuckle 114. The adjustment member 157 is provided on one end with a toothing 163 and on the other end with a slot 164 for a screwdriver (not shown) and is otherwise of circular cylindrical shape. For the supporting of the adjustment member 157 in the slide 155, bearing holes 165 and 166 are provided in the wall sections 159 and 160 of said slide, the bearing hole 165 in the wall section 159 serving to support the end of the adjustment member 157 which is provided with the slot 164 and the bearing hole 166 in the wall section 160 serving to support the end of the adjustment member 157 which is provided with the toothing 163.
On the one longitudinal edge of the hinge arm 158 there is provided a toothing 167 which cooperates with the toothing 163 of the adjustment member 157 for the continuous displacement of the hinge arm 158 in the direction indicated by the arrow F.
The base body, premounted with the slide 155, is then, after the insertion of the adjustment screw 35 into the recess 37, pushed by the turning of this adjustment screw into the opening 105 of the anchoring part 106. In this condition, the first hinge part is so fastened in the borehole 42 of the cabinet wall 1 that the slot 162 is accessible through the recess 126 of the anchoring part 106 from the front surface 1' of the cabinet wall 1. Now the hinge arm 158 can be introduced into the slot 162, which continues, in the region between the wall sections 159 and 160, in a laterally open groove 169 which, with the slide 155 pushed over the base body 156, is at least partially closed laterally by the surface side of the plate-shaped part 156' facing the wall section 160. After the engagement of the toothing 163 into the start of the toothing 167, the hinge arm is pulled into the slot 162 or the groove 169 by turning the adjustment member 157 (turning it in counterclockwise direction in the view seen in FIG. 13) so that the hinge arm 158 lies in part in the groove 169 between the wall section 160 and the surface side of the plate-shaped part 156' facing said wall section and in part also in the slot 162 and the end thereof provided with the hinge knuckle 114 protrudes from the recess 162 of the anchoring part 106. By the turning of a screw 170 into a threaded borehole 171 in the wall section 160, the hinge arm 158 is secured in the slide 155, the screw 170 passing through a borehole 162 in the wall section 159, through the lengthwise recess 168 and a slot 173 which extends in the direction of the axis or of the double arrow F. The screw 170 also serves at the same time to guide the slide 155 on the base body 156 and prevents a turning of the two parts with respect to each other. Since the toothing 163 extends into the groove 169 and thus is in engagement with the toothing 167 of the hinge arm 158, and hinge arm 158 can be displaced in the direction of the axis indicated by the double arrow F relative to the slide 155 and to the anchoring part 106 out of the position shown in FIG. 16 into the position shown in FIG. 17, and vice versa.
The adjusting of the hinge arm 158 along the three coordinate axes D, E and F, the axis D extending in the direction of the pivot axis of the hinge, the axis E perpendicular to the surface of the cabinet wall 1, and the axis F parallel to the surface of the cabinet wall 1 and at the same time perpendicular to the pivot axis of the hinge, is effected in the manner that first of all the base body 156 is adjusted, together with the slide 155, in the direction of the axis E by means of the adjustment screw 35. Thereupon the hinge arm 158 is possibly adjusted in the direction of the axis F by suitably turning the adjustment member 156. Then by displacing the slide 155 relative to the base body 156 the hinge arm 158 can be adjusted in the direction of the axis D. When the adjustment along the axes D and F has been concluded, the screw 170 is tightened, with the result that the head of this screw is pressed firmly against the surface side of the wall section 159, which surface side remains visible even after the insertion of the anchoring part 106 into the borehole 52 of the cabinet wall 1. The wall sections 159 and 160 are moved slightly towards each other as a result of the deformability of the material used for the slide 155, so that the part of the hinge arm 158 contained in the groove 169 is clamped fast between the wall section 160 and the surface side of the plate-shaped part 156' facing said wall section, which is possible in the manner than the depth of the groove 169 is selected somewhat smaller than the thickness of the hinge arm 158 or than the thickness of the wall-shaped material used for said hinge arm.
The embodiment shown in FIGS. 13-19 thus again the the advantage that by means of a single screw 170 both the hinge arm 158 is secured against undesired displacement in the direction of the double arrow F and a locking of the slide 155 on the base body 156 is obtained. FIGS. 18 and 19, similar to FIGS. 11 and 12, show the two possible extreme positions of the slide 155 with respect to the displacement in the direction of the double-arrow D.
