is arranged so as to be slidable in the direction of the groove of the arm 1 (in the direction of arrow B in Fig. 1), and furthermore, this slide fitting 4
The base metal fitting 5 is attached to the back surface of the slide metal fitting 4 so as to be slidable in a direction perpendicular to the sliding metal fitting 4 (in the direction of arrow C).

3 shows an exploded perspective view of FIG. 2, and FIG. 4 shows a perspective view of the slide fitting 4 turned over. That is, the slide fitting 4 has a slide guide groove 6 extending in the width direction formed on its back surface, and has tapered surfaces 6a and 6b on both sides facing the groove, and has a tapered surface on the bottom surface 6c of the groove on the side of the tapered surface 6a. An inclined protrusion 7 having the same inclination direction as 6a is integrally provided, and an elongated screw insertion hole 9 is formed in the center of the back surface 6c, through which a height adjustment screw 8 (FIG. 3) can freely pass. Further, as shown in FIG. 3, an engagement hole 10 in the form of an elongated hole with a wide end at one end is provided at one end of the surface side of the slide fitting 4.
The tip of the width adjustment screw 11 screwed into the width adjustment screw hole 26 of the grooved arm 1 shown in the figure is inserted through the width adjustment screw hole 26. As shown in FIG. 5, the width adjusting screw 11 is provided at its tip with a hook portion 11b whose diameter is enlarged through a small diameter portion. The tip of the width adjusting screw 11 is engaged with the slide fitting 4 by inserting it and hooking it into the elongated hole. Furthermore, flanges 12, 12 are provided protrudingly on both sides of the other end on the surface side of the slide fitting 4, and the flanges 12, 12 are slidably inserted between the web and the protrusion 1a formed by inwardly driving both flanges of the arm 1 shown in FIG. possible,
A recess 13 with a knurled bottom surface is formed between the flanges 12, 12, and the threaded end of the depth adjustment screw 14 screwed into the depth adjustment screw hole 27 of the grooved arm 1 shown in FIG. 1 is pressed into contact. possible.

On the other hand, the base metal fitting 5 has a pair of stoppers 16, 16 protruding from one side of the flat body 15, and the side end surface between the two stoppers 16, 16 corresponds to the tapered surface 6a of the slide metal fitting 6. A protrusion 17 is integrally provided on the other side of the flat main body 15, and the end surface is finished into a tapered end surface 5b so as to correspond to the tapered surface 6b of the slide fitting 6. A pair of inclined holes 18, 1 into which the inclined protrusions 7, 7 can be inserted are provided in the center of the main body 15.
8, and a screw hole 19 into which the height adjustment screw 8 is screwed is provided, and screw insertion holes 20, 20 are formed at both ends of the flat plate-like main body 15.

The connection between the base metal fitting 5 and the slide metal fitting 4 is as follows.
Both tapered end surfaces 5a and 5b of the base metal fitting 5 are brought into contact with the tapered surfaces 6a and 6b of the slide metal fitting 4, respectively, and the inclined protrusion 7 is inserted into the inclined hole 18 and engaged, and the base metal fitting 5 is slid into the slide guide groove 6. The height adjustment screw 8 is inserted into the screw insertion slot 9 of the slide fitting 4 and screwed into the screw hole 19 of the base fitting 5. In this case, the tapered surface 7a of the protrusion 7 comes into contact with the tapered inner surface 18a of the inclined hole 18. Note that the width between the stoppers 16 and 16 is set larger than the width of the slide fitting 4, and the inclined hole 1
The width of the protrusion 8 is also set larger than the width of the protrusion 7. Therefore, by loosening the height adjustment screw 8,
The base fitting 5 can be freely slid along the slide guide groove 6 in the direction perpendicular to the slide fitting 4, that is, in the direction of arrow C in FIG. 2, within the range between the stoppers 16, 16. By tightening the height adjustment screw 8, the base metal fitting 5 can be brought into pressure contact with the slide metal fitting 4 and fixed at an arbitrary sliding position.

On the other hand, the slide fitting 4 is inserted into the groove on the rear end of the arm 1 as shown in FIG. 12 is inserted between the protrusion 1a of the arm 1 and the web, so that it is slidably held in the direction of the groove of the arm 1 (in the direction of arrow B). Then, by screwing and adjusting the width adjustment screw 11, the slide fitting 4 is attached to the protrusion 1 of the arm 1.
The rotation can be adjusted using a as a fulcrum.In other words, the angle between the slide fittings 4 of the arm 1 can be adjusted by moving one end of the slide fitting 4 back and forth in the direction of arrow D in Figure 1 (direction perpendicular to the web surface of the arm 1). Ru. Further, by tightening the depth adjustment screw 14 and pressing the screw tip into the recess 13 of the slide fitting 4, the slide fitting 4 can be fixed at any position slid in the direction of arrow B. In this case, since the engagement hole 10 has an elongated hole shape, the slide fitting 4 can be moved in the direction of arrow B without being hindered by the width adjustment screw 11.

As shown in FIG. 1, a fastening driver insertion hole 21 is formed between the width adjustment screw hole 26 and the depth adjustment screw hole 27 provided in the web of the groove arm 1. The height adjusting screw 8 shown in FIG. 2 can be screwed and adjusted from the opposite direction.

Attaching this type of sliding hinge to furniture is
A door (not shown) is screwed to the door mounting bracket 3 through the screw insertion hole 3a, and the base bracket 5
Screw insertion hole 20 into the inner surface of the side plate of box-shaped furniture
Screw through. In that case, groove arm 1
Install so that the groove direction matches the depth direction of the box-shaped furniture. Further, the adjustment of the depth, width, and height of this slide hinge is performed as follows. That is, after loosening the depth adjustment screw 14 and adjusting the slide fitting 4 in the direction of arrow B, that is, in the furniture depth direction, tightening the depth adjustment screw 14 to fix the slide fitting 4, and then screwing the width adjustment screw 11. Adjust the angle between the slide fitting 4 and the grooved arm 1 (adjustment in the direction of arrow D), that is, adjust the door in the furniture width direction, and then loosen the height adjustment screw 8 to adjust the slide fitting 4. After adjusting the base fitting 5 by sliding it in the direction of arrow C, that is, in the height direction, the height adjusting screw 8 is tightened and fixed.

However, with each adjustment screw 14, 11, 8, the depth,
After adjusting the width and height, each adjusting screw 14,
It is necessary to prevent loosening of the adjustment screws 11 and 8, and conventionally, each adjusting screw 14, 11, 8 is coated with adhesive and the threaded hole 27, 26 of the grooved arm 1 is inserted.
Since the adjustment screws 14, 11, and 8 are screwed into the screw holes 19 of the base metal fitting 5, there is a problem that the loosening prevention performance of each adjustment screw 14, 11, 8 is not constant due to differences in the amount of adhesive applied and the drying time.

Therefore, an object of this invention is to provide a slide hinge adjusting screw locking cap that can reliably prevent each adjusting screw from loosening.

An embodiment of this invention will be described with reference to FIGS. 6 to 9. That is, as shown in FIG. 6, the slide hinge adjustment screw locking cap E has a cap E that can be pulled out and fitted into the driver insertion hole 21 shown in FIG. In addition to forming a protrusion 23 that becomes the protrusion 1, it also serves as a second protrusion that can be inserted and fixed into the cross groove 11a for driver insertion of the width adjustment screw 11 shown in FIG. 7 near one end of the back surface of the main body 22. Locking protrusion 2
4 is provided protrudingly, and a hookhole-shaped notch 29 is provided at the other end of the main body 22 as shown in FIG.
5 forms a U-shaped clamping part 28 that can clamp both sides of the circumference of the depth adjusting screw 14. In this case, as is clear from FIGS. 6 and 8, since narrow portions are formed in both side pieces 25 by the hookhole-shaped notches 29, both side pieces 25 can elastically expand outwardly. It is possible. Therefore, as shown in FIG. 9, when the depth adjusting screw 14 is held between the side pieces 25 so that the circumference of the depth adjusting screw 14 fits into the circular arc portion of the keyhole-shaped notch 29, the depth adjusting screw 14 is elastically clamped by the pieces 25 on both sides, thereby preventing the depth adjustment screw 14 from loosening, and also by inserting a screwdriver into the cross groove 14a and removing the depth adjustment screw 14.
It becomes possible to forcefully rotate the

As a result of this configuration, each adjustment screw 14, 1
After adjusting the depth, width and height of the slide hinge with steps 1 and 8, as shown in Figures 8 and 9,
Connect the protrusion 23 of the locking cap E to the grooved arm 1.
When the driver is inserted into the driver insertion hole 21, the protrusion 23
This hides the cross groove 8a (Fig. 7) of the height adjustment screw 8, prevents it from coming into contact with the outside, and prevents the height adjustment screw 8 from loosening. 11 into the cross groove 11a to prevent the cap from loosening.
8 can clamp both sides of the circumferential body of the depth adjusting screw 14 to prevent it from loosening. Moreover, since the depth adjustment screw 14 is prevented from loosening by holding both sides of the circumferential body of the depth adjustment screw 14 between the side pieces 25 of the U-shaped clamping part 28, the depth adjustment screw 14 is forcibly tightened by inserting a screwdriver into the cross groove 14a. In other words, the depth of the slide hinge can be adjusted while the locking cap E is attached to the slide hinge. Furthermore, since the locking cap E is removable, the depth, width, and height of the slide hinge can be readjusted. Furthermore, by attaching the locking cap E, the width adjusting screw 11, the height adjusting screw 8, and the driver insertion hole 21 can be hidden, so that the aesthetic appearance can be improved.

As described above, according to the slide hinge adjustment screw locking cap of this invention, each adjustment screw can be reliably prevented from loosening, and the depth of the slide hinge can be adjusted while the locking cap is attached to the slide hinge. This has the effect of being able to do this.
