[0004]

[Problems to be solved by the device]

 However, in order to perform temporary fixing with the bracket described above, it is necessary to push down the locking member forming the temporary fixing claw against the biasing force of the coil spring, but the biasing force of the coil spring is It is strongly set so that the can be fixed firmly. For this reason, a certain amount of force is required to perform the temporary fixing operation, which is not easy. Moreover, since the temporary fixing claw is integrally formed, it does not have elasticity by itself, and the elasticity of the coil spring is not provided. You have to rely on it, and there is a danger that it will be damaged during temporary fixing. Therefore, an object of the present invention is to provide a curtain rail bracket in which the temporary fixing operation can be easily performed by imparting elasticity to the temporary fixing claw itself.

[0005]

[Means for Solving the Problems]

 The means for solving the above-mentioned problems will be described with reference to FIG. 1 of an embodiment. The configuration is such that the locking member 3 is slidably mounted in the front-rear direction on the lower surface of the mounting bracket 2, and The coil spring 4 is interposed between the locking member 3 and the locking member 3 and the locking member 3 is biased forward so that one locking groove of the curtain rail is locked to the front end edge 6e of the fitting 2. A curtain rail bracket 1 for attaching a curtain rail by locking the other locking groove to the front end edge 9 of the locking member 3, and the front end edge side of the locking member 3 of the coil spring 4 is An extending portion 11 formed of a linear body is formed so as to extend to a lower portion of the locking member 3, and the temporary rail of the rail is provided on the extending portion 11 before the locking of the front end edge 9 of the locking member 3 of the curtain rail. Temporary fixing to stop Claw 11a is formed Characterized in that a curtain rail bracket 1, the lower surface of the locking member, may form a regulating portion for regulating the lateral shake of the temporary fixing nails.

[0006]

[Action]

 That is, according to the above configuration, in order to temporarily fix the curtain rail, one of the locking grooves of the curtain rail is locked to the front end edge of the fitting and the other locking groove is extended to the lower part of the locking member. It is locked to the temporary stop claw of the extended portion. Then, at the time of this temporary fixing operation, the temporary fixing claw extended from the coil spring does not wait for the elastic force of the coil spring, but moves appropriately by the elastic force of the extending portion made of the linear body to facilitate the temporary fixing. Suru

Further, the restricting portion formed on the lower surface of the locking member is arranged so as to sandwich both sides of the extending portion made of a linear body, or to be interposed between the extending portions. Prevents lateral movement of the temporary fixing claw of the extension that moves back and forth by the stopping action.

[0008]

[Effect of device]

 As a result of the above, according to the present invention, the temporary fixing is performed by the extending portion formed of the linear body extending to the end portion of the coil spring, and the elastic force of the extending portion is larger than that of the entire length of the coil spring. Since it is weak, temporary fixing can be done easily. For this reason, even if the biasing force of the coil spring is set to a high level, it has little effect on the temporary fixing.By setting the biasing force of the coil sprig to a high level in this way, a stronger fixed state of the curtain rail can be obtained. it can.

Moreover, since the temporary fixing claw is formed at the end of the coil spring, unlike the conventional case where the temporary fixing claw is directly formed on the locking member, the temporary fixing claw is unexpectedly damaged by the temporary fixing overload. It is also possible to protect from being damaged, and it is also possible to adjust the operation load at the time of temporary fixing operation and the temporary fixing state by appropriately bending the extending portion made of a linear body.

Further, since the locking member is formed with the regulating member for regulating the lateral deviation of the temporary fixing claw, the temporary fixing claw is laterally shaken at the time of the temporary fixing, resulting in an insufficient temporary fixing state. Can be reliably prevented.

As shown in FIG. 1, the bracket 1 has a mounting bracket 2 to be mounted on a wall surface and a lower surface side of the mounting bracket 2. It is composed of a locking member 3 which is slidably mounted, and a coil spring 4 which is interposed between the locking member 3 and the above-mentioned mounting member 2 to bias the locking member 3.

The above-described mounting member 2 is formed by pressing a single metal plate stamped to a predetermined size, and has a vertical portion 5 that comes into contact with a wall surface and the like, and horizontally protrudes forward from this vertical portion 5. It has a horizontal part 6 that operates. An insertion hole 5a for inserting a screw is formed in the upper central surface of the vertical portion 5 described above, and a stopper 6a bent downward and a slide hole 6b having a predetermined length are formed in the horizontal portion 6. Are formed side by side in the front-back direction. Further, guide pieces 6d for allowing the sliding of the locking member 3 are formed by bending the lower end edges of both side walls 6c, 6c formed on the rear portion (vertical portion side) of the horizontal portion 6. There is. A locking portion 6e bent downward is formed at the front edge of the horizontal portion 6.

The locking member 3 has a storage recess 7 formed in the center of the rear portion of the upper surface for storing the coil spring. The front end of the storage recess 7 has a front end that extends downward as shown in FIG. A through hole 7a having a shape is formed.

Further, on the front edge of the upper surface, a slide protrusion 8 that slides in the slide hole 6b of the mounting member 2 is provided upright. Below the slide protrusion 8, the front end face 3a is retracted by a predetermined amount, and a main stop claw 9 for locking the curtain rail is projected on the front end face 3a. As shown in FIG. 3, an inclined surface 9a is continuously provided downward and rearward. Further, as shown in FIGS. 2 and 3, a convex portion 3b for locking a jig such as a driver is vertically provided behind the through hole 7a.

In the coil spring 4 described above, the front end portion of the main body 10 is extended downward to form an extending portion 11 made of a linear body, and the lower end of the extending portion 11 is bent forward. The temporary fixing claw 11a is formed. The temporary fixing claw 11a projects downward through the through hole 7a when the coil spring 4 is housed in the housing recess 7 of the locking member 3 and is located below the inclined surface 9a, as shown in FIG. As described above, the temporary setting is made possible before the curtain rail is locked to the main locking claw 9. Further, as shown in FIG. 3, the length of the main body 10 is such that the front end of the slide protrusion 8 of the locking member 3 slides when the mounting member 2 and the locking member 3 are interposed. It is set so as to have a slight biasing force by coming into contact with the front end of the hole 6b.

Next, the operation and effect will be described. To attach the curtain rail 12 to the bracket 1 configured as described above, the engaging groove 12a on the front side of the curtain rail 12 is engaged with the engaging portion 6e at the front end edge of the mounting member 2, and The rear side is pushed up, the rear side locking groove 12b is locked to the temporary locking claw 11a of the extending portion 11 extended to the lower portion of the locking member 3, and the temporary locking is performed. Then, at the time of this temporary fixing operation, the temporary fixing claw 11a extended from the coil spring 4 is appropriately moved by the elastic force of the extending portion 11 made of a linear body without waiting for the elastic force of the coil spring 4.

The stop groove 12b is locked to the main stop claw 9 (see FIG. 4).

Therefore, as described above, the temporary fixing claw 9 is formed in a linear body extending from the coil spring 4, and the elasticity of the extending portion 11 is greater than the elasticity of the entire length of the coil spring 4. Since it is also weak, temporary fixing can be done easily. Therefore, even if the biasing force of the coil spring 4 main body 10 is set to be high, it has little effect on the temporary fixing. By setting the biasing force of the coil sprig 4 main body 10 to be high in this way, A strong fixed state can be obtained.

Moreover, since the temporary fixing claw 11a is formed on the end portion of the coil spring 4, unlike the case where the temporary fixing claw 11a is directly formed on the locking member 3 as in the conventional case, the temporary fixing claw 11a is overloaded. It is possible to protect it from being accidentally damaged by, and it is also possible to adjust the operation load at the time of temporary fixing operation and the temporary fixing state by appropriately bending the extending portion made of a linear body. Further, since the good temporary fixing can be performed as described above, the curtain rail 12 can be easily and accurately fixed by the one-touch type. (Second Embodiment) FIG. 5 is a perspective view showing a locking member 31 and a coil spring 32. As shown in FIG. 5, a temporary fixing claw 33a is formed at the tip of the lower surface of the locking member 31.

The above-described mounting member 35 is formed by pressing a single metal plate punched to a predetermined size, and has an overall shape that is long in the horizontal direction. A locking portion 37 that is bent downward is formed at the front edge, a contact portion 38 that contacts the ceiling surface is formed behind the locking portion 37, and a rear portion of the contact portion 38 is formed. The slide member 39 is formed so that the above-mentioned locking member 31 slides.

An insertion hole 38 a for inserting a screw is formed in the center of the contact portion 38 described above, and a stopper 39 a formed by bending the slide portion 39 downward is formed. Side walls 40, 40 are formed on both side edges of the contact portion 38 and the slide portion 39, and the locking member 31 can be slid at a position where the locking member 31 slides. The guide pieces 40a, 40a having a predetermined length are bent at the lower end edge.

The locking member 31 has a storage recess 41 for storing the coil spring 32 on the upper surface, and the front end of the storage recess 41 corresponds to the width of the extending portion 33 of the coil spring 32. A rectangular through hole 41a penetrating downward is formed with the above-described size. The through hole 41a is bent into an L shape through the inside of the restricting portion 34 described above, and is formed on the front end surface of the restricting portion 34. It communicates with the opening portion 34a having a width corresponding to the projecting portion 33. From the through hole 41a to the opening 34a, the extension 33 of the coil spring 32 is housed so as not to laterally shift, and the extension 33 is temporarily fixed as shown in FIG. 8 and FIG. It can be moved back and forth. In addition, a step 34b having a higher rear is formed at a position slightly recessed from the opening 34a so that the above-described temporary stop to final stop and the final stop to temporary stop can be switched more smoothly.

Further, above the opening 34 a and on the front end edge of the locking member 31, a main locking claw 42 for locking the carten rail is provided so as to project. Has an inclined surface 42a continuously extending downward and rearward. Further, as shown in FIG. 7, convex portions 43, 43 for locking a jig such as a driver are vertically provided on both sides of the rear side position of the above-mentioned restriction portion.

When the curtain rail 12 is temporarily fixed to the bracket 36, the extending portion 33 of the coil spring 32 and the temporary fixing claw 33a retreat, but at this time, the restricting portion 34 formed on the lower surface of the locking member 31 is used. However, by sandwiching both sides of the extension portion 33, lateral extension of the extension portion 33 that retracts is prevented. Therefore, the temporary fixing claw 33a does not recede straight and is not laterally displaced, and a reliable temporary fixing state can be obtained with sufficient biasing force.

It should be noted that the extending portion and the regulating portion that regulates the lateral movement of the stop claw are not shaped so as to surround the extending portion as described above, but may extend to both sides of the extending portion, for example. It is a wall body that is oppositely placed so as to sandwich the portion, but as in the locking member 45 shown in FIG. 10, the extension portion is formed by interposing between the extension portions 46 formed of two linear bodies. It may be a rail body 47 serving as a rail for the forward and backward movement of 46.

Since the locking member 31 is the same as that in the second embodiment, the same reference numeral is given and its description is omitted.

Further, the mounting fitting 54 is substantially the same as that in each of the above-described embodiments, and therefore will be briefly described. As shown in FIG. 12, the mounting metal fitting 54 is formed by pressing a single metal plate punched to a predetermined size, and is fixed to the wall surface with a vertical portion 55 and a front portion from the vertical portion 55. And a horizontal portion 56 that horizontally protrudes.

A locking portion 57 bent downward is formed at the front end edge of the above-mentioned horizontal portion 56, and at the rear of this locking portion 57, a sliding step is provided in which the above-mentioned locking member 31 slides down. The portion 58 is formed. A stopper 58a formed by bending downward is formed on the slide portion 58, and at a position where the locking member 31 slides, a guide piece 59a having a predetermined length that allows the locking member 31 to slide. , 59a are bent and formed on the lower end edges of both side walls 59.

As shown in FIG. 11, the coil spring 52 described above has an extension 53 formed of a single linear body from the front end of the main body 52a, and the lower end of the extension 53 is coiled. The temporary fixing claw 53a is formed by winding the coil appropriately several times in a direction different from the spring by 90 degrees. When the coil spring 52 is housed in the housing recess 41 of the locking member 31, the temporary fixing claw 53a protrudes forward from the opening 34a of the restricting portion 34 and is located below the inclined surface 42a. As shown in FIG. 7, the curtain rail 12 is set so that it can be temporarily fixed before being locked to the main locking claw 42.

Next, the operations and effects will be described, omitting the portions overlapping with those of the second embodiment. The curtain rail 12 is temporarily fixed to the bracket 51 while the temporary fixing claw 53a formed by winding a linear body in a coil shape flexibly receives the load applied when the curtain rail 12 is locked by its curved surface. Therefore, an excessive load is not applied to only a part of the temporary fixing claw 53a, the bending of the temporary fixing claw 53a can be prevented, and a reliable temporary fixing state can be obtained.

The temporary fixing claw 53a may be a spiral temporary fixing claw 62 like the coil spring 61 shown in FIG. 14, for example, instead of the coil shape as in the previous example.
