Description

  The present invention relates to an anti-rattle tool for a sliding fitting against a groove rail of a Kamoi.

  In general, between the top neck of the sliding door that slides along the groove rail of the Kamoi and the groove rail that accepts it, it is about on both sides of the back (front and back) of the sliding door because of the necessity of the sliding door operation and opening / closing action. A clearance of 0.5 to 1.0 mm is ensured, but this dimension is merely a standard and is not always standardized.

  As a result, for example, when receiving wind blown through a building or the suction force of a ventilation fan in use, there is a concern that the upper neck of the sliding door repeatedly comes into contact with the groove rail of the Kamoi, causing unpleasant rattling noise.

Japanese Patent Laid-Open No. 11-303520 has been proposed as a means for preventing rattling of such a sliding joinery. According to this, the cushioning material (5) is applied to the upper end neck (3) of the joinery (1) from above. Since it is only necessary to fix it to the state, it can be said that there is an advantage that it can be applied easily and at low cost without the need for special groove processing on the existing joinery (1).
Japanese Patent Laid-Open No. 11-303520

  In the configuration of the known invention, the cushioning material (5) for preventing rattling of the joinery (1) is “resin materials such as vinyl chloride and polyethylene, especially soft resin materials, or synthetic rubbers, synthetic It is formed by leather, leather, etc. It can also be formed by a metal plate having elasticity such as a spring plate. ”, And the cushioning material (5) itself has“ material or The clearance is automatically adjusted (absorbed) by “structural (shape) elasticity or flexibility”.

  However, considering that the clearance is usually a small size of about 0.5 to 1.0 mm on both sides of the back (front and back) of the fitting (1), in theory, the clearance is actually reduced. It is extremely difficult to automatically adjust (absorb) only the cushioning material (5) fixed to the upper surface (3a) of the joinery (1).

  That is, when the cushioning material (5) is formed of a soft material, the contact edge portions (7) and (8) can be easily brought into contact with the opposed inner surfaces (4a) and (4b) of the groove interior (4). Sliding with 4a) and 4b) is poor, and the resistance at the time of opening and closing in the joinery (1) becomes excessive.

  In order to relieve the frictional braking force of the contact edge portions (7) and (8), the contact edge portions (7) and (8) are formed into a triangular shape or a partial thick wall, or thin enough to secure the hollow portions (10) and (11). If this occurs, the contact edge portions (7) and (8) are prematurely worn out and yielded, and the stability and durability of the anti-rattle action cannot be maintained.

  On the other hand, when the cushioning material (5) is formed of a hard material, the sliding of the abutting edge portions (7) and (8) with respect to the opposing inner surfaces (4a) and (4b) of the groove interior (4) is improved, but the above clearance is reduced. It is difficult to automatically adjust (absorb), and if the contact edges (7) and (8) are brought into contact with the opposing inner surfaces (4a) and (4b) as much as possible, a rubbing noise will be generated. In addition, it is necessary to prepare and prepare various cushioning materials (5) having a shape corresponding to the wide and narrow changes of the clearance and high-precision dimensions, which is inferior in versatility.

  Further, when the cushioning material (5) is formed from an elastic metal plate, not only the above-mentioned problem of the cushioning material (5) made of a hard material, but also the wooden material rail member (2) by the cushioning material (5) of the metal plate. May be cut off, and the clearance spreads over time, causing rattling noise.

  Further, as is apparent from the first embodiment of FIGS. 1 and 2 and the third embodiment of FIG. 6, the cushioning material (5) is retrofitted and fixed to the upper surface (3a) of the fitting (1) as a crowned state. For this reason, it becomes difficult to move the fitting (1) into and out of the groove (4) of the rail member (2), and the upper surface (3a) of the fitting (1) is preliminarily limited. It is necessary to process low.

  It is clear that this becomes more and more pronounced when the cushioning material (5) is attached over the entire length of the joinery (1) or when the cushioning material (5) is formed from a hard material. It is.

  The present invention aims to solve such problems, and in order to achieve these objects, in claim 1, a rigid synthetic resin fixed housing having a fixed depth embedded in and integrated with the upper end neck of a sliding joinery. When,

  A substantially inverted L-shaped hard plate comprising a substantially horizontal slat extending from the upper opening surface of the fixed housing into the groove rail of the Kamoi and a mounting leg plate hanging from the base end of the slat into the fixed housing. It consists of synthetic resin movable vanes,

  As a pair of symmetrical straight backs facing the movable blades, the lower end portions of the mounting leg plates are pivotally supported respectively to horizontal fulcrum ribs projecting inward integrally from the corresponding mid-depth position of the fixed housing. As well as

  A first compression coil spring and a second compression coil spring are interposed between the mounting leg plates facing each other and the blade blades facing each other, and the blade plates are stretched to the groove rail of the Kamoi. It is characterized by being urged to oppress the state.

  Further, according to claim 2 subordinate to claim 1, the projecting tip of the slat in the movable blade is shaped into a circular arc convex curved surface in plan view that can make point contact with the groove rail of the Kamoi.

  In claim 3 subordinate to claim 1, the fulcrum rib protruding inwardly from the fixed housing is shaped into an arc convex curved surface,

  The lower end portion of the mounting leg plate of the movable blade is formed as a pair of hooks that are alternately staggered between the movable blades, and is formed into an arc concave curved surface that meshes with the fulcrum rib.

  In claim 4 subordinate to claim 1, the movable blade is made of hard synthetic resin having high wear resistance and lubricity, such as nylon and polyacetal, and is substantially inverted with a thick blade plate and a thin mounting leg plate. Integrally molded into an L-shape,

  While installing the first compression coil spring between the spring receiving projections projecting inward from the midway depth position of the mounting leg plate,

  A second compression coil spring having a tension weaker than that of the first compression coil spring is interposed between the opposing ends of the spring receiving concave grooves cut out at the base end portion of the blade.

  Further, in claim 5 subordinate to claim 1, the fixed housing is made of a hard synthetic resin having high wear resistance and lubricity such as nylon or polyacetal, and is seen in a plan view and a bottom view extending along the longitudinal direction of the joinery. Shaped into an elongated oval shape,

  A pair of opposing long sides of the elliptical long side wall and the short side walls that divide it form a rectangular movable blade receiving chamber in a flat and bottom view at the center of the fixed housing, and

  An extension portion in which the short side wall of the partition hangs from the upper surface of the opening of the fixed housing by a certain height is defined so as to function as a guide piece of a blade plate extending from the upper surface of the opening of the fixed housing.

  According to the configuration of the first aspect, the blade of the movable blade protruding from the fixed housing embedded and integrated in the upper end neck portion of the sliding joinery is a tension of the compression coil spring interposed between the pair of symmetrical straight backs facing each other. Since it is designed to constantly press against the groove rails of Kamoi under the energizing force of expansion, the clearance between the groove rail and the top neck can be absorbed by itself, even if it changes widely. The rattling noise can be surely prevented.

  Further, since the blades of the movable blades are elastically brought into contact with the groove rails of the Kamoi due to the urging and expanding urging force of the compression coil springs, there is no possibility of giving excessive resistance to the sliding action of the joinery. With the uniform tension expansion and energizing force, a stable backlash absorbing action can be performed at all times, and there is no risk of accidentally falling off from the upper neck of the joinery.

  In particular, if the structure of claim 2 is adopted, the slats of the movable blades are in point contact with the groove rails of the Kamoi, so that the resistance at the time of opening and closing in the joinery can be suppressed, and the opening and closing operation is light and smooth. There is an effect that can be done.

  If the structure of Claim 3 is employ | adopted, while making a pair of back-and-back movable blades the same structure, it is assembled and integrated in a symmetrical parallel state to the fixed housing, so that the hooks of the mounting leg plates on the movable blades are fixed to the fixed housing. The fulcrum rib on the side can be pivotally and reliably supported without interfering with each other, and the mass production effect of the movable blade is excellent.

  If the structure of claim 4 is adopted, the movable blade that rubs against the groove rail of Kamoi is made of a hard synthetic resin with high wear resistance and lubricity such as nylon and polyacetal. There is no risk of yielding and the like, and the durability can be improved. Nevertheless, the clearing urging force of the compression coil spring can exhibit a clear absorption effect.

  Furthermore, if the structure of claim 5 is adopted, the durability of the fixed housing can be improved, and this is firmly and stably fixed to the corresponding oval embedded recessed groove that is router-processed on the upper neck of the joinery. In addition to being able to be embedded well, a pair of guide pieces that suspend from the short side wall of the movable blade receiving chamber by a certain height can prevent unauthorized distortion and deflection of the blades in the movable blade. There is also an effect that can be brought into contact with the groove rail of the Kamoi evenly and stably as a pair of backs.

  Hereinafter, based on the drawings, the specific configuration of the present invention will be described in detail. The rattling prevention tool of the present invention is a sliding fitting (D) along the groove rail (1) of the duck (B) as shown in FIGS. Embedded in the narrow upper end of the neck (2) to absorb the clearance (C) between the upper end neck (2) and the groove rail (1) and prevent the generation of unpleasant rattling noise It is.

  In addition, the sliding fitting (D) is not limited to the sliding door shown in the figure, and a door cage, a variable partition, a partition, etc. can also be adopted. Sometimes formed in a row.

  6-14 which showed the rattling prevention tool of the said fitting (D), (M) is a long and narrow elliptical shape in flat and bottom view from nylon, polyacetal, and other hard synthetic resins with high wear resistance and lubricity. (For example, width: about 8 mm × length: about 30 mm) A fixed housing that is injection-molded and has a certain depth (S1) (for example, about 14 mm). ) A movable vane whose center passes through a rectangular shape (for example, width: about 5.6 mm x length: about 16.7 mm) through a pair of left and right partitioning short side walls (4) orthogonal to each other. It is defined as a receiving room (R).

  In addition, the pair of left and right partition short side walls (4) defining the movable blade receiving chamber (R) has a fixed height from the overhanging flange (5) that rims the upper surface of the opening of the fixed housing (M) in an elliptical shape. The extension portion that is suspended by (H) (for example, about 5 mm) can be used as a guide piece (6) of the movable blade (A), which will be described later, and can regulate unauthorized distortion and deflection of the movable blade (A). ing.

  Similarly, (7) is a pair of straight-backed horizontal projections projecting inwardly into the movable blade receiving chamber (R) from a midway depth position of the opposing long side wall (3) in the fixed housing (M). Each of the fulcrum ribs extends along the long side wall (3), and the protruding surface thereof has an arc-shaped curved surface.

  In addition, (8) is a vertical wedge rib protruding integrally from the trunk surface as a plurality (four in the illustrated example) scattered in the periphery of the fixed housing (M). The embedding fixing force with respect to the upper end neck part (2) of (D) is given up.

  On the other hand, the movable blade (A) mentioned above is injection molded from a hard synthetic resin having excellent wear resistance and lubricity, such as nylon and polyacetal, into an almost inverted L shape as shown in FIGS. As a pair of straight backs having the same configuration, they are integrated into the movable blade receiving chamber (R) of the fixed housing (M) in a symmetrical parallel state from above.

  That is, the movable blade (A) has a substantially horizontal blade plate (9) having a constant width (W) (for example, about 9.2 mm) that projects from the upper surface of the opening of the fixed housing (M), and its blade plate ( 9) and a mounting leg plate (10) that hangs by a certain depth (S2) (for example, about 12 mm) from the base end portion of the stationary housing (M) into the movable blade receiving chamber (R). ) And the mounting leg plate (10) have the same fixed length (L) (for example, about 16 mm) and are slightly shorter than the length of the movable blade receiving chamber (R) (about 16.7 mm exemplified above). .

  Moreover, the lower end portion of the mounting leg plate (10) is shaped as a pair of left and right hooks (11a) (11b) in a circular arc concave surface that can be matched with the horizontal fulcrum rib (7) on the fixed housing (M) side. Yes. Of the pair of left and right, one hook (11a) is assigned to the middle part of the mounting leg plate (10) having a fixed length (L), and the other hook (11b) is also assigned to the end part of the mounting leg plate (10). Has been placed.

  Therefore, the mounting leg plate (10) of the movable blade (A) is inserted into the movable blade receiving chamber (R) of the fixed housing (M) from above, and the hooks (11a) and (11b) at the lower end thereof are fixed. By engaging with the horizontal fulcrum rib (7) on the housing (M) side, it is assembled and integrated with the fixed housing (M).

  In that case, since the pair of front and back of the movable blade (A) has the same configuration, by inserting them into the movable blade receiving chamber (R) in a symmetrical parallel state, the mounting leg plate (10) described above As is apparent from FIG. 8, the hooks (11a) and (11b) can be engaged with the fulcrum ribs (7) without any risk of interference as alternating staggered states between the movable blades (A).

  Then, since the fulcrum rib (7) has an arc convex curved surface, and the hooks (11a) (11b) mesh with this as a circular concave curved surface, the pair of right and left movable blades (A) have their horizontal fulcrum ribs. With the longitudinal axis of (7) as the center, the pivotally attached state as shown in FIG. 10 can be maintained, and there is no possibility that the whole will rotate so as to be tilted together.

  Further, as shown in FIG. 14, the vane plate (9) of the movable vane (A) has a fixed height (H) of the guide piece (6) suspended from the upper surface of the opening of the fixed housing (M) (illustrated above). The tip portion that is thicker than the fixed thickness (T) (for example, about 1.2 mm) of the mounting leg plate (10) and that projects from the upper surface of the opening of the fixed housing (M) has a thickness (T1) substantially equal to about 5 mm). 3 and FIG. 12, as a circular convex surface (12) as shown in the plan view, is shaped so as to be able to make point contact with the groove rail (1) of Kamoi (B), and the sliding action of the fitting (D) There is no risk of excessive resistance.

  (13) is an inclined sloped surface notched at the upper end corner of the projecting tip of the blade (9), and the upper neck of the fitting (D) ( 2) can be smoothly inserted and removed from the groove rail (1) of the Kamoi (B).

  Further, (14) is a spring receiving convexity projecting integrally inward from a mid-depth position of the mounting leg plate (10) forming the movable blade (A), and between the opposing face-to-face pairs. Is inserted with a first compression coil spring (15) made of stainless steel wire, whereby the mounting leg plate (10) is pressed against the long side wall (3) of the movable blade receiving chamber (R), and its mounting leg plate The hooks (11a) and (11b) forming the lower end of (10) are prevented from accidentally falling off from the fulcrum rib (7) on the fixed housing (M) side.

  (16) is a spring receiving concave groove cut out at the base end of the blade (9) that also forms the movable blade (A), and the stainless steel wire no. Two compression coil springs (17) are inserted and installed, so that the slats (9) of the movable blades (A) are pressed against the groove rails (1) of the Kamoi (B) at all times. The repression is energized.

  Moreover, the first and second compression coil springs (15) and (17) extend along the width direction of the fixed housing (M) as an arrangement relationship orthogonal to the rotation fulcrum rib (7) of the movable blade (A). Needless to say. In that case, the tension of the second compression coil spring (17) can be adjusted according to the weight of the fitting (D), but in relation to the first compression coil spring (15), the tension of the second compression coil spring (15) is greater than the tension of the first compression coil spring (15). It is preferable to set weakly.

  (18) is a notch groove for reducing the weight of the blade plate (9) based on the fact that the thickness (T1) of the blade plate (9) is thicker than the thickness (T2) of the mounting leg plate (10). Yes, and provided as a pair in parallel with the peripheral portion of the spring receiving groove (16). In addition, it is desirable that the fixed housing (M) and the movable blade (A) of the anti-rattle tool be colored with the same color as the fitting (D) in which the fixed housing (M) is embedded.

  The rattling prevention tool of the present invention comprises the fixed housing (M) as described above and a pair of right and left movable blades (A) assembled and integrated with the fixed housing (M). As shown in FIG. 5, at the position biased to the left and right ends of the sliding joinery (D), a pair of embedded recessed grooves (G) for the fixed housing is router-processed into the narrow upper neck (2), and the inside The fixed housings (M) are embedded and integrated from above.

  Needless to say, the fixed housing (M) of the rattling prevention tool and the recessed groove (G) thereof extend as an elongated ellipse along the longitudinal direction of the fitting (D). As shown in FIGS. 2 and 5, the flange (5) is positioned and locked to the opening edge of the corresponding recessed groove (G), and the movable blade (A The upper surface of the slat (9) is kept at the same height as or lower than the upper surface of the upper neck (2) of the fitting (D).

  And if the upper end neck part (2) of the said fitting (D) is inserted in the groove rail (1) of a duck (B), it will be urged | biased as a tension expansion state by the 2nd compression coil spring (17) of the rattle prevention tool. As a result of the slats (9) of the movable blades (A) being pressed against the inner wall surfaces (19) facing the groove rails (1), the upper neck (2) of the fitting (D) and the duck The clearance (C) secured between the groove rail (1) of (B) can be absorbed almost evenly on both sides of the back of the fitting (D) and generates rattling noise. It is not.

  Since the fixed housing (M) of such rattle prevention tool is embedded and integrated in the upper end neck (2) of the fitting (D), there is no possibility of dropping off, and the pair of right and left movable blades (A) Since the blades (9) are interleaved between each other, the second compression coil spring (17) is elastically pressed and urged toward the inner wall surface (19) of the groove rail (1). Even if there is a wide and narrow change in (C), it is possible to always respond to the change, and the versatility is excellent.

  Furthermore, since the projecting front end portion of the movable blade (A) from the fixed housing (M) in the blade plate (9) is shaped as an arc convex curved surface (12) in plan view, the groove rail (1) There is no possibility that the resistance received at the time of opening and closing of the sliding joinery (D) will be excessively increased due to point contact with the inner wall surface (19). This is because the movable blade (A) is a molded product made of a hard synthetic resin with high wear resistance and lubricity, and it will work organically. Does not occur and has excellent durability.

  Further, the upper surface of the slat (9) is kept below the same height as the upper surface of the upper neck (2) of the joinery (D), and receives the tension and expansion biasing force of the second compression coil spring (17). Therefore, coupled with the fact that the upper end corner of the slat (9) is notched as an inclined slope surface (13), the upper end neck (2) of the joinery (D) is used as the groove rail of the Kamoi (B). (1) can be easily put in and out, and there is no risk of restricting the operation.
