Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle attachment structure for attaching a handle to a cylinder lock incorporated in a door from both sides of the door.

[0002]

2. Description of the Related Art Generally, door handles for operating a cylinder lock incorporated in a door are attached to both sides of the door through a seat for attaching a handle, and when the handles are turned, a cam shaft is turned to turn the cylinder. The structure is such that the lock latch retracts and unlocks. Regarding such a door handle mounting structure, for example, Japanese Patent Laid-Open No. 7-3
There is a technique disclosed in Japanese Patent No. 24529.

In this prior invention, a plurality of centering guide holes that penetrate the cylinder portion of the cylinder lock embedded in the door.
Shafts provided with 27 and 27 and extending from mounting seats 30 and 30 attached to both sides of the door with respect to the centering guide hole
The structure is such that 31 and 33 are inserted and connected.

[0004]

However, in this conventional structure, the centering guide hole is formed in the lock cylinder portion incorporating the complicated lock mechanism.
Since the structure penetrates 27, 27, the arrangement of parts and space of the mechanism in the lock cylinder part is limited, and since the centering guide hole must be formed through, the lock cylinder part must be manufactured with a completely new mechanism. However, this is a major cause of cost increase. In addition, when assembling, left and right centering guide holes 2
There was a problem that the work of inserting the shafts 31 and 33 into 7 and 27 was quite troublesome and the workability was poor.

Therefore, the main object of the present invention is to provide a door handle mounting structure that solves the above-mentioned conventional problems.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, in the door handle mounting structure according to the present invention, the handle mounting seats 4 are provided from both sides of the door with respect to the cam hole 3 which laterally penetrates the cylinder portion 2 of the cylinder lock 1 embedded from the door end surface. In the door handle mounting structure in which the handles 6 and 6 are mounted via 5, the cylinder 2 is projected from one of the left and right seats 4.5 toward the cylinder 2 of the cylinder lock from above and below. Upper and lower rods 7 and 8 are formed, and a receiving portion for receiving a tip end portion of the rod is provided on the other receiving seat 9 and 10 facing each other, and further, on at least one of the upper and lower surfaces of the tubular portion 2. A structure is provided in which a concave groove 11 into which any one of the upper and lower rods 7 and 8 is fitted is provided.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of a door handle mounting structure according to the present invention, in which reference numeral 1
Is a cylinder lock embedded from the end face of the door A, in which the latch 12 is retracted and unlocked by rotating a cam shaft 3a having a cam hole 3 penetrating the cylinder portion 2 thereof. Has become. Since the internal lock mechanism of the cylinder lock 1 as described above is conventionally known, the detailed description of the mechanism part is omitted.

Thus, a seat mounting hole B is formed through the door so that the cylinder portion 2 of the cylinder lock is exposed from both sides of the door A. At both ends of the seat mounting hole B, handle mounting mounting holes B are provided. Seats 4 and 5 are fitted. The handle mounting seats 4 and 5 are provided with an insertion hole 14 through which the square shaft 13 of the one door handle 6 is inserted, and the square shaft 14 is inserted into the lock cylinder portion 2.
It is configured such that it penetrates through the cam hole 3 and is fitted into an angular bearing hole 15 provided in the door handle 6 on the opposite side and fixed with a screw.

One of the left and right handle mounting seats 4.5, for example, the seat 4 projects toward the cylinder portion 2 of the cylinder lock to sandwich the cylinder portion 2 from above and below, and the lower rods 7 and 8. Is formed, and a receiving portion that receives the tip end portions of the rods 7 and 8 is provided on the other receiving seat where 9 and 10 face each other. In the present embodiment, the upper rod 7 is formed of a relatively wide cylinder whose upper surface is a circular arc and its mask is flat in its cross-sectional shape, and the lower rod 7 is a cylinder having an inverted U-shaped cross section. It is formed as a set of two. Further, the receiving portion 9 for receiving the upper rod 7 is formed in the shape of an arcuate eave, and the receiving portions 10, 10 for receiving the lower rod 8 are formed by pin bodies having an outer diameter to be fitted into the rod. Further, on the lower surface of the tubular portion 2, recessed grooves 11, 11 with which the lower rods 8, 8 are engaged are provided at a position where the rod is fitted into the receiving portion.

In the door handle mounting structure constructed as described above, the handle mounting seats 4 and 5 are fitted through the openings at both ends of the seat mounting hole B of the door, and are projected from one of the seats 4. In addition, the tips of the lower rods 7 and 8 are fitted into the receiving portions 9 and 10 of the other receiving seat 5. At this position, the lower rods 8 and 8 are engaged with the recessed grooves 11 and 11, and the relative positions of the handle mounting seats 4 and 5 and the lock tube portion 2 are determined. As a result, the centering of the cam hole 3 with respect to the angular axis 13 of the handle 6 is determined, the handles 6, 6 can be easily attached, and the upper and lower rods 7 of the handle mounting seats 4, 5 are
Since the tube portion 8 sandwiches the tubular portion 2 from above and below, the rattling of the handle mounting seat can be eliminated. Also groove
Since 11 and 11 are formed on the outer surface of the cylindrical portion, the lower rod 8,
The operation of engaging the groove 8 with the groove 11 is easy.

The present invention does not specify the shape of the rods 7 and 8. For example, as shown in FIG. 4, the upper rod 7 may be formed of two pipes on the left and right, and the receiving portion 9 of the pipe may be formed of a pin. Also, the upper and lower rods 7 and 8
One of them may be provided on the other handle mounting seat 5, and a receiving portion for receiving this may be provided on the handle mounting seat 4. Further, as shown in FIG. 5, an upper rod body 7 and a lower rod body 8 are formed by a shaft, and a receiving portion 10 for receiving them is provided.
The 10 may be formed in a pipe shape.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments, and has the constitutional requirements of the present invention and has the above-mentioned object. As long as it is achieved and has the following effects, it can be appropriately modified and implemented.

[0013]

Since the door handle mounting structure of the present invention is constructed as described above, it is possible to center the cam hole with respect to the angular axis of the door handle at the same time as mounting the handle mounting seat. According to the invention, since the upper and lower rods of the handle mounting seat sandwich the tubular portion from above and below, rattling of the handle mounting seat can be eliminated, and a groove for receiving the rod is formed on the outer surface of the tubular portion. Since it is easy to engage the corresponding rod with the groove, the cylinder lock can be processed by simply forming the groove on the outer peripheral surface of the cylinder. Without having to do so, it is only necessary to process the cylinder casing of the conventional cylinder lock, and there are various remarkable effects that the manufacturing cost can be suppressed.
