In a state where the door roller 1 is engaged between side wall parts 9A,9B of a bottom rail B2 to contact a substantially horizontal top face of a head 5A of the flat head machine screw 5 to an undersurface of an upper wall 8, a tip of a Phillips screwdriver D can engage with the cross-recess. A round hole 6 with a smaller inner diameter than an outer diameter of a shaft S is formed on the upper wall 8. When the flat head machine screw 5 is rotated to tightening direction with the driver D, the tip inclined part of the driver D contacts to a peripheral wall forming the round hole 6, as the inner diameter of the round hole 6 is smaller than the outer diameter of the shaft S. Thus, the upper wall 8 of the bottom rail B2 moves down without being detached along with the head 5A of the flat head machine screw 5 that moves down by pressing and rotating operation of the driver D.SELECTED DRAWING: Figure 8

Description

  The present invention relates to a pull-type fitting that is built in a Kendon manner between upper and lower rails of a frame, in which a door wheel with a building adjustment function is attached to a lower arm.

As a pull-type fitting such as a screen door and a sliding sash built into the Kendon type (倹 飩 type) between the upper rail and the lower rail of the frame body, with a door adjustment with a building adjustment function attached to the lower arm, A pull type equipped with a door with a relatively simple structure that eliminates the mounting frame for mounting the wheel frame that supports the wheel so that it can move in the vertical direction with respect to the lower rail. There is a joinery (a joiner with a door) (see, for example, Patent Document 1).
The door wheel (8) in the pulling type fitting (1) of Patent Document 1 supports the wheel (11) and the wheel (11), and the pulling type fitting (1) has a groove (7) in the lower arm (3) (7). ) Having a substantially inverted U-shaped wheel frame (9) and a head with a hook (16a) screwed substantially perpendicularly to the upper piece (9c) of the wheel frame (9). An adjustment screw (16) is provided, and a vertically elongated protrusion (13, 13) is formed on the side piece (9a) of the wheel frame (9). Further, the door roller (8) abuts the lower surface of the upper wall portion (3c) of the lower frame (3) of the lower fitting (1) of the fitting (1) by pulling the flange (16b) of the head (16a) of the adjustment screw (16). And is used in a state in which the head (16a) is exposed from the hole (17) formed in the upper wall (3c) of the lower rod (3). The wheel frame (9) is supported so as to be movable in the vertical direction by engaging 13, 13) with the guide grooves (14, 14) formed in the side wall (3a) of the lower rod (3).
Here, the installation adjustment of the pull-type fitting (1) of Patent Document 1 is performed by rotating the head (16a) of the adjustment screw (16) of the door pulley (8) with a screwdriver from the indoor side, and lower armature (3) This can be done by changing the distance in the height direction between the heel (16b) contacting the lower surface of the wheel and the wheel (11).

Japanese Patent No. 2745288

In the conventional pull-type joinery such as Patent Document 1, the resistance when the lower arm (3) and the door pulley (8) with a building adjustment function move up and down relatively is very small, so that it moves up and down freely. For example, when holding the vertical rod (4, 4) of the joinery, the door cart (8) is lowered to the lowest position with respect to the lower rod (3). The workability of the work of building the joinery in the Kendon style between the rail and the lower rail is reduced.
In addition, when it is configured to give a certain amount of resistance when the lower arm (3) and the door pulley (8) with a building adjustment function move up and down relatively, For example, if the weight of the pull-type fitting is light, such as a screen door, even if the adjustment screw (16) is rotated in the direction of tightening by the screwdriver, the adjustment screw (16) is lowered from the flange (16b). In some cases, the lower surface of (3) is separated and does not follow, and in that case, another operation of pushing down the joinery is required, so that the workability of the installation adjustment is lowered. In addition, if the adjustment screw (16) is not adjusted so that the lower surface of the lower rod (3) is in contact with the upper surface of the rod (16b), the pull-type fitting (for example, a screen door) is slid after the installation adjustment. In some cases, glare may occur.

Furthermore, when performing the operation | work which attaches a doorwheel (8) to a lower arm (3), the protrusion (13,13) formed in the side piece part (9b) of a wheel frame (9) is made into an armpit (3) Since it is necessary to be engaged with the guide grooves (14, 14) formed in the side wall (3a), the lower collar (3) needs to be deformed, so that the work efficiency of the work is reduced, and the pulling type The manufacturing cost of joinery increases.
In addition, a guide groove (3) for supporting the wheel frame (9) is formed on the side wall (3a) of the lower rod (3), and an adjusting screw (3c) is formed on the upper wall (3c) of the lower rod (3). Since the hole (17) for exposing the head (16a) of 16) is formed, the processing of the guide groove (3) for the side wall (3a) and the hole (17) for the upper wall (3c) Since it is necessary to perform this processing in a separate process, the number of processing steps increases, and the manufacturing cost of the pull-type joinery increases.
In addition, since the wheel (11) is pivotally supported by a wheel frame (9) having a substantially inverted U-shaped cross section, it cannot be provided with a steady rest function, so that a separate steady rest must be used in combination. Therefore, the manufacturing cost of pull-type joinery increases.

  Therefore, in view of the above-described situation, the present invention intends to provide a pull-type fitting that can improve the workability of the installation adjustment work and can reduce the manufacturing cost.

  In order to solve the above-mentioned problem, the pull-type joinery according to the present invention is a pull-type that is constructed in a Kendon style between the upper rail and the lower rail of the frame body in which a door wheel with a built-in adjustment function is attached to the lower arm. A flat machine screw with a cross hole screwed into a wheel on which the door wheel rolls on the lower rail, a base that pivotally supports the wheel, and a screw hole formed in the upper surface of the base. The door wheel is inserted from the lower surface opening of the lower heel and is inserted between the side walls of the lower heel in the prospective direction, and the flat machine screw with a cross hole is formed on the lower surface of the upper wall of the lower heel. A round hole formed so that the tip of the Phillips screwdriver can be engaged with the cross hole in a state where the substantially horizontal upper surface of the head is in contact, and the inner diameter is smaller than the outer diameter of the shaft of the Phillips screwdriver. It is formed on the upper wall portion.

According to such a configuration, when the installation adjustment of the pull-type joinery is performed from the indoor side, the upper wall portion of the lower lid so that the tip of the Phillips screwdriver can be engaged with the cross hole of the flat machine screw with a cross hole The round screw formed on the flat screw screw is engaged with the cross hole from above and pushed and rotated in a direction to loosen the flat machine screw. Since the lower surface of the upper wall portion of the lower heel is in contact with the upper surface, the joinery that has pushed up the upper wall portion of the lower heel rises.
Also, when the flat screw is rotated with a Phillips screwdriver, the inner diameter of the round hole formed in the upper wall of the lower collar is smaller than the outer diameter of the Phillips screwdriver shaft. Since the inclined portion abuts on the peripheral wall forming the round hole, the operation of pushing and turning a Phillips screwdriver into the cross hole makes the weight light, for example, when the pull-type joinery is a screen door. Even if it exists, the upper wall part of the lower gutter will descend without separating together with the head of the flat machine screw that descends with the operation of pushing the plus driver. Therefore, since the joinery reliably follows the lowering operation of the head of the flat screw, it is not necessary to perform another operation of pushing down the joinery, so that the workability of the installation adjustment can be improved. In addition, since the lower heel is surely lowered following the downward movement of the head of the flat small screw, there is no occurrence of glitches when sliding a pull-type fitting (for example, a screen door) after the installation adjustment.

Here, it is preferable that a protrusion protruding toward the side wall portion into which the base of the door wheel is inserted is formed integrally with the base.
According to such a configuration, depending on the size and number of protrusions protruding from the base toward the side wall of the lower arm, a predetermined time when the lower arm and the door with a building adjustment function move up and down relatively is predetermined. In addition to providing resistance of the size, by adding such resistance, the door cart descends to the lowest position when a pull-type fitting is built between the upper rail and lower rail of the frame body in the Kendon style Therefore, workability of erection work does not deteriorate.
In addition, since the protrusions can be integrally formed on a synthetic resin base, for example, an increase in manufacturing cost can be suppressed while realizing a configuration that provides a predetermined resistance.

Moreover, it is more preferable that a projecting piece projecting on the upper surface of the base of the door pulley is fitted into a guide hole formed in the front and rear direction of the upper wall portion of the lower lid.
According to such a configuration, the door roller is moved up and down with respect to the lower arm by the guide hole formed in the upper wall portion of the lower arm and the projecting piece that protrudes from the upper surface of the base of the door wheel and fits into the guide hole. Since it is supported so as to be movable in the direction, there is no uneven engagement portion in the side wall portion of the lower arm as in Patent Document 1, so there is no need to deform the lower arm when performing the work of attaching the door wheel to the lower arm Since the work efficiency does not decrease, the manufacturing cost of the pull type joinery can be reduced.
In addition, a round hole for inserting a Phillips screwdriver during installation adjustment, and a guide hole for supporting the door wheel so as to be movable in the vertical direction with respect to the lower arm, both are formed in the upper wall part. Since the round hole and the guide hole can be processed in the same process, the manufacturing process does not increase as in Patent Document 1, and the manufacturing cost of the pull-type joinery can be reduced.

Further, it is more preferable that the lower rail is sandwiched between a guide piece formed at the lower end portion of the base of the door wheel and a flange formed on the outer periphery of the wheel of the door wheel.
According to such a configuration, since the lower rail is sandwiched between the guide piece of the base body and the heel portion of the wheel, the door wheel has an anti-sway function in the prospective direction. Since it is not necessary to attach, the manufacturing cost of a pull-type fitting can be reduced.

  The door to the building adjustment function according to the present invention is the door to the building adjustment function that is used by being attached to the lower arm of the pull-type fitting.

As described above, according to the pull type fitting according to the present invention,
(1) When the flat machine screw with a cross hole of a door roller with a construction adjustment function is rotated in the direction to be tightened with a Phillips screwdriver, the plus screwdriver is engaged with the cross hole and pushed to turn, for example, a pull-type fitting Even if the weight is light as in the case of a screen door, the upper wall of the lower arm is lowered without separating with the head of the flat machine screw that is lowered as the screwdriver is pushed and turned. Therefore, since the joinery surely follows the downward movement of the head of the flat screw, it is not necessary to perform another operation for pushing down the joinery, so that workability of the installation adjustment can be improved.
(2) According to the structure in which the lower rail is sandwiched between the guide piece formed on the lower end portion of the base of the door wheel and the flange formed on the outer periphery of the wheel of the door wheel, the guide piece of the base and the wheel hook Since the lower rail is sandwiched by the door, the door has a steady-state function in the prospective direction, so there is no need to attach a steady rest to the lower arm of the door, so that the manufacturing cost of the pull-type fitting can be reduced,
There are remarkable effects such as.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste.
In this specification, the front-rear and left-right directions are the front-rear and left-right directions in a state of facing outdoors (the pull-type fittings are viewed from the indoor side), the front-rear direction (indoor / outdoor direction) is the "expected direction", The sliding direction of the joinery) is called the “finding direction”.
Moreover, let the figure which looked at the pull-type fitting from the room inner side.

As shown in the front view of FIG. 1, a screen door A that is a pull-type fitting according to an embodiment of the present invention includes doors 1 and 1 with a building adjustment function before and after the direction H of the lower arm B 2. In addition, automatic detachment prevention devices 10 and 10 are provided in front of and behind the direction H in which the upper collar B1 is found, and is raised and dropped between the upper rail R1 and the lower rail R2 of the frame F, that is, the Kendon type (倹 飩 type). Built in. And in the state where the installation of the screen door A is completed, the screen door A is prevented from coming off by the automatic come-off prevention devices 10 and 10 which are automatically operated by the building work.
Moreover, as shown in the partial vertical front view of FIG. 2 and the vertical left side view of FIG. 3, the door wheel 1 is located between the side wall portions 9A and 9B before and after the prospective direction I on the rear side (indoor side) of the lower arm B2. The upper surface of the lower wall B2 is mounted below the round hole 6 of the upper wall portion 8, and the substantially horizontal upper surface of the head 5A of the flat machine screw 5 with a cross hole is in contact with the lower surface of the upper wall portion 8. In the state where the projecting pieces 2C and 2C projecting from the upper surface of the base 2 are fitted into the guide holes 7 and 7 formed before and after the finding direction H with respect to the round hole 6 of the wall portion 8, the wheel 3 is moved to the lower rail R2. Roll over.

The guide rods 7 and 7 formed in the upper wall portion 8 of the lower collar B2 and the projecting pieces 2C and 2C fitted into the guide holes 7 and 7 projecting from the upper surface of the base body 2 of the door wheel 1 On the other hand, since the door pulley 1 is supported so as to be movable in the vertical direction, since there is no uneven engagement portion in the side wall portion of the lower lid as in Patent Document 1, when performing the operation of attaching the door pulley 1 to the lower bush B2. Since it is not necessary to deform the lower arm B2 and the work efficiency is not lowered, the manufacturing cost of the screen door A can be reduced.
In addition, the upper wall includes a round hole 6 for inserting a Phillips screwdriver during installation adjustment, which will be described later, and guide holes 7 and 7 for supporting the door wheel 1 movably in the vertical direction with respect to the lower arm B2. Since the round hole 6 and the guide holes 7 and 7 can be machined in the same process since they are formed in the part 8, the machining process is performed as in the configuration in which the upper wall part and the side wall part are perforated as in Patent Document 1. Since it does not increase, the manufacturing cost of the screen door A can be reduced.

As shown in the perspective views of FIGS. 4 (a) and 4 (b), and the exploded perspective view of FIG. 5, the door 1 with a built-in adjustment function according to the embodiment of the present invention includes wheels 3 and wheels made of synthetic resin. 3 is composed of a synthetic resin base 2 that pivotally supports 3 and a flat cross-head screw 5 with a steel cross hole that is screwed into a screw hole 2B formed on the upper surface of the base 2. A guide piece 2D is formed on the wheel 3 and a flange 3B is formed on the wheel 3.
Here, the stepped rivet 4 made of steel is inserted into the through hole 3A of the wheel 3 and the through hole 2A of the base 2 and the shaft end is caulked so that the wheel 3 is pivotally supported by the base 2.
Further, as shown in FIG. 4B, protrusions 2E and 2E are integrally formed on the front surface (outside surface) of the base 2, and as shown in FIG. 3, the protrusion 2E is a side wall of the lower collar B2. Projecting toward the portion 9A.

Next, attachment of the door pulley 1 with a building adjustment function to the lower arm B2 will be described.
As shown in the perspective view of FIG. 6 and the arrow in the partial longitudinal left side view of FIG. 7, the door cart 1 is shown in FIGS. 2 and 3 by the one-touch operation of inserting the door wheel 1 from the lower surface opening C of the lower arm B 2. Is fitted into the lower arm B2.
In this state, as described above, the projecting pieces 2C and 2C of the door pulley 1 are fitted into the guide holes 7 and 7 of the upper wall portion 8 of the lower collar B2, and the head 5A of the cross machined flat head screw 5 of the door wheel 1 is provided. The substantially horizontal upper surface of this is in contact with the lower surface of the upper wall portion 8.

Further, as shown in FIG. 3, since the projection 2E is pressed against the side wall portion 9A, a predetermined amount of resistance is given when the lower arm B2 and the door wheel 1 move up and down relatively, so that FIG. When the screen door A is built in the Kendon type between the upper rail R1 and the lower rail R2 of the frame F shown, the door 1 does not descend to the lowest position, so the workability of the construction work does not deteriorate. In addition, the magnitude of the resistance can be changed by changing the size and number of protrusions 2E protruding from the base body 2 of the door wheel 1 toward the side wall 9A of the lower arm B2.
Furthermore, since the protrusion 2E can be integrally formed on a synthetic resin base 2 manufactured by, for example, injection molding, an increase in manufacturing cost can be suppressed while realizing a configuration that provides a predetermined resistance.

As shown in FIG. 7, a guide groove G is formed between the guide piece 2D at the lower end of the base body 2 and the flange 3B of the wheel 3, and between the upper rail R1 and the lower rail R2 of the frame F. In the state shown in FIG. 3 in which the screen door A is built in, the lower rail R2 is in the guide groove G in FIG. 7, and the guide piece 2D formed at the lower end of the base 2 of the door 1 and the wheel 3 of the door 1 The lower rail R2 is sandwiched between the flange 3B formed on the outer periphery of the lower rail.
Therefore, since the door pulley 1 has the anti-rest function of the prospective direction I, it is not necessary to attach the anti-rest member separate from the door pulley 1 to the lower arm B2, so the manufacturing cost of the screen door A can be reduced.

Next, the installation adjustment of the screen door A will be described.
As shown in the partial cross-sectional perspective view of FIG. 8 and the main part enlarged partial vertical front view of FIG. 9, the cross hole 5B on the upper surface of the flat machine screw 5 with the cross hole of the door pulley 1 with a building adjustment function includes The tip of a Phillips screwdriver (cross screwdriver) D can be engaged from the indoor side through the round hole 6 formed in the upper wall portion 8 of B2.
The inner diameter d1 of the round hole 6 is formed smaller than the outer diameter d2 of the shaft S of the plus driver D (d1 <d2).

When performing installation adjustment of the screen door A from the indoor side, a cross screw on the upper surface of the flat screw 5 with a cross hole is inserted from above into the round hole 6 formed in the upper wall 8 of the lower arm B2. By engaging and pushing the hole 5B and rotating the flat machine screw 5 in the loosening direction, the lower surface of the upper wall portion 8 of the lower collar B2 comes into contact with the substantially horizontal upper surface of the head 5A of the flat machine screw 5. As a result, the screen door A pushed up on the upper wall portion 8 of the lower arm B2 rises.
Further, when the flat screw 5 is rotated in the direction of tightening with the Phillips screwdriver D, the inner diameter d1 of the round hole 6 formed in the upper wall portion 8 of the lower collar B2 is larger than the outer diameter d2 of the axis S of the Phillips screwdriver D. Since the tip inclined portion E of the plus driver D is in contact with the peripheral wall forming the round hole 6, the plus driver D is pushed and turned by engaging the cross hole 5B and pushing the plus driver D. Along with the head 5A of the flat small screw 5 that descends, the upper wall portion 8 of the lower collar B2 descends without separating. Therefore, since the screen door A reliably follows the lowering operation of the head 5A of the flat machine screw 5, it is not necessary to perform another operation of pushing down the screen door A, so that the workability of the installation adjustment can be improved. In addition, the lower eyelid B2 surely descends following the downward movement of the head 5A of the flat small screw 5, so that there is no occurrence of glitches when the screen door A is slid after the installation adjustment.

  In the above description, the case where the sliding-type fitting of the present invention is the screen door A is shown, but the sliding-type fitting of the present invention may be a sliding sash or a sliding sliding door.
