Abstract

PROBLEM TO BE SOLVED: To provide a door pull device which reduces protrusions, from surfaces, of door pulls mounted on the surface and backside of a door, and enables the door pull to be mounted with adequate strength from the side of one surface of the door. SOLUTION: The paired door pulls 1 and 2 are made equal in external shape to each other. Mounting holes 8 are formed at the upper and lower ends of the recess of the door pull 1. In the upper and lower parts of the backside, the door pull 1 is provided with a square sliding recess 9 extended in a thickness direction, the door pull 2 is provided with a sliding recess 10, and a connecting tool 3 is inserted into each of the recesses 9 and 10. The connecting tool 3, which is formed in a rectangular parallelepiped shape, is provided with two adjusting holes 12 and 13 at one end and a long hole-shaped mounting part 11 at the other end, and fixed by a fixing tool 5, which is inserted into the door pull 2 and pressed into the adjusting hole 12 or 13 through a fixing hole, for the purpose of being mounted on the door. A screw 4 screwed into the mounting hole 8 of the door pull 1 is fixed to a door body through the mounting part 11. Consequently, the obverse and reverse door pulls 1 and 2 are mounted integrally with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puller device for mounting a pair of pullers on both front and back surfaces of a door, and has a sufficient mounting strength while minimizing a protrusion from the surface of the door. In addition, the present invention has been improved so that it can be attached from one side of the door and can be attached to doors having different thicknesses.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Application No. 53-112620.
As described in the microfilm of No. 55-29667, a door lock has been proposed in which the mounting seats 6.6 on the front and rear surfaces of the door are attached by using a mounting screw 19 and a screw tube 20 to attach them. . In addition, it is common practice to attach the tabs to the front and back surfaces of the door with wood screws.

[0003]

In the former conventional example, the door can be attached from one side of the door or can be attached to a door having a different thickness. However, when this is applied to a handle, the flange can be attached. If the thickness is reduced to minimize the protrusion from the door surface, there is a problem that the flange is deformed when the thickness is strongly increased in order to increase the mounting strength. In addition, if the flange portion is thick and the protrusion size from the surface of the door is large, there is a disadvantage that when a plurality of sliding doors are used as a sliding door, the protruding portion hits and cannot be pulled. The size of the protrusion from the surface must be reduced. Also, in the latter conventional example, since the tabs are attached to both the front and back sides of the door with wood screws,
There is a problem that installation is troublesome and troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a pull device for solving the above-mentioned problem, wherein a pair of pulls are mounted on the front and back surfaces of a door. Projecting, the connector is provided with a long slot-shaped or long groove-shaped mounting portion in the thickness direction of the door to be mounted,
A screw inserted from the mounting hole of the other tab is screwed into the mounting portion, and the pair of tabs is mounted on the door.

[0005]

Since the present invention is constructed as described above, a tab can be attached from one side of the door according to the thickness of the door.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The pulling device of the present invention uses a door D with a pulling handle 1 and a pulling handle 2.
Can be attached across. The handle 1 and the handle 2 are manufactured by the same mold and have the same basic structure. However, as will be described later, holes (mounting holes 8.8 and fixing holes
6.16) are different.

The handle 1 has a shape in which four sides of a vertically long rectangle are formed into a large arc shape when viewed from the front, and has a concave portion 6 in the center and a flange portion 14 around the concave portion 6. Recess 6
Is provided with an inner peripheral surface 7 whose bottom surface is almost the same as the outer shape of the handle 1 and which rises obliquely outward from the bottom surface, and is provided at upper and lower portions of the inner peripheral surface 7 at a substantially right angle to the inclined surface. A circular mounting hole 8.8 is provided. Further, sliding recesses 9.9 extending in the thickness direction in a rectangular shape are formed in the upper and lower portions of the back surface of the puller 1.
Is provided. The mounting holes 8 penetrate from the inner peripheral surface 7 to around the entrance of the sliding recesses 9.

The handle 2 has the same outer shape as the handle 1, and has fixing holes 16 at right angles to the upper and lower sliding recesses 10 from outside. The flange of the tab 2 is denoted by reference numeral 15.

The connector 3 for connecting the tabs 1 and 2 has a rectangular parallelepiped shape and has two circular adjusting holes 12 and 13 arranged at one end side in the longitudinal direction, and has a long length at the other end side in the longitudinal direction. A hole-shaped mounting portion 11 is provided. Insert the adjustment holes 12 and 13 sides of the connecting device 3 into the sliding recesses 10 of the pull 2,
The fixing tool 5 such as a spring pin is pressed into the adjusting hole 12 or 13 from the fixing hole 16 to fix the connecting tool 3 to the pull tab 2. As described above, in the present embodiment, the connecting tool 3 is
The protrusion length can be adjusted and attached. However, it is also possible to simply fix the two adjustment holes without adjusting the protrusion length by using one adjustment hole (in this case, the length is adjusted). It is good to prepare a plurality of connecting tools different in shape), and the connecting tool 3 may be integrally formed with the handle 2. Further, the mounting portion 11 of the connecting tool 3 may be a long groove having an open end, instead of a long hole.

Next, a method of attaching the puller device to the door D will be described. Doors 1 and 2 with holes in door D
2 is inserted so that the door D is sandwiched between the flanges 14 and 15, and the connecting tools 3.3 are inserted into the sliding recesses 9.9. Then, the screw 4 is inserted from the mounting hole 8 and screwed and fixed to the mounting portion 11 of the connector 3 and the door D. If this is done by the upper and lower mounting holes 8, 8, the mounting is completed. With such an attachment method, even if the screw 4 is strongly tightened, the flange portions 14 and 1
5 is hardly deformed, and a sufficient mounting strength can be obtained.

FIGS. 4A and 4B show adjustment holes 13.
The fitting 5 is press-fitted to the door, and corresponds to a door having a relatively small thickness. The door is adjusted from a minimum thickness (A) to a maximum thickness (B) and attached. (C) and (D) show the fixture 5 pressed into the adjustment hole 12.
This corresponds to a door having a relatively large thickness, and indicates that the door can be mounted with its thickness adjusted from the minimum (C) to the maximum (D).

[0012]

As described above, according to the present invention, the door has a sufficient mounting strength while minimizing the projection size from the surface of the door, and has a different thickness from one side of the door. There is an effect that it can be mounted corresponding to the above.
