Therefore, the handle 30 is held in the normal state not only by gravity but also by the elastic force of the spring 44a. It is possible to prevent the handle 30 from vibrating at the same time, and to prevent the generation of abnormal noise such as clattering due to collision with other members, to prevent the deterioration of the sense of quality in terms of auditory appearance, and to further facilitate the improvement of the design. .

Further, as described with reference to FIGS. 1 to 8, according to the door handle structure according to the embodiment, the fixing screw hole 42 has an opening at one end on the outer peripheral surface 40d of the joint member 40, and the joint member An outer peripheral surface 40 d of the handle 30 faces the peripheral plate portion 32 of the handle 30 . When the handle 30 is in the normal state, at least a portion of the one end opening of the fixing screw hole 42 is covered by the peripheral plate portion 32, and the fixing screw hole 42 cannot be operated. Further, when the handle 30 is in an inclined state, the opening at one end of the fixing screw hole 42 is not covered with the peripheral plate portion 32, and the fixing screw hole 42 becomes an operable state in which the fixing screw 42a can be operated.

As described above, according to the door handle structure according to the embodiment, one end opening of the fixing screw hole 42 is covered with the peripheral plate portion 32 when the handle 30 is in the normal state, and when the door handle is not operated, it is fixed. The screw holes 42 are hardly visible from the outside, the appearance can be easily improved, and the design can be further easily improved. In addition, it becomes difficult to recognize the existence of the fixing screw 42a, and it is impossible to operate to loosen the fixing screw 42a in the normal state, so that crime prevention can be improved.

Conversely, when the handle 30 is in an inclined state, the one end opening of the fixing screw hole 42 is not covered by the peripheral plate portion 32, and the fixing screw hole 42 is in an operable state in which the fixing screw 42a can be operated. Therefore, by performing a normal handle operation for opening the door 1, the fixing screw 42a can be loosened or tightened, thereby facilitating attachment and detachment of the door handle structure.

As another method for making the fixing screw 42a operable to be loosened or tightened by performing a normal handle operation for opening the door 1, a pair of side cutouts in the handle 30 is provided. It is conceivable to shift the position of 32b upward or downward to increase the depth of the pair of side cutouts 32b.

If the position of the pair of side cutouts 32b is shifted up or down and the cutout depth of the pair of side cutouts 32b is increased, for example, when the handle 30 is rotated to the right, one of the side cutouts 32b and one end opening of one of the fixing screw holes 42 are overlapped, and one of the fixing screws 42a can be operated. The opening overlaps and the other fixing screw 42a can be operated, and both fixing screws 42a can be loosened or tightened.

However, the lock mechanism of the door handle structure having the latch bolt is often structured so that the handle can only be rotated in one direction from the non-operated state, and the handle can only be rotated in one direction from the non-operated state. With the structure, both the pair of fixing screws 42a cannot be operated depending on the method of shifting the positions of the pair of side cutouts 32b upward or downward.

According to the door handle structure of the embodiment, when the handle 30 is in an inclined state, both of the openings at one end of the pair of fixing screw holes 42 are not covered by the peripheral plate portion 32, and the pair of fixing screw holes 42 are Both are in an operable state in which the fixing screw 42a can be operated. Therefore, even with a lock mechanism that can only rotate the handle 30 in one direction from the non-operating state, both of the pair of fixing screws 42a can be loosened or tightened, and the applicable models of the lock device can be expanded.

It is also conceivable to shift one side notch 32b upward and the other downward, but this is not preferable in terms of design because it is asymmetrical, and the door handle structure of the embodiment is more designable. Easy to improve.

Further, as described with reference to FIGS. 1 to 8, according to the door handle structure according to the embodiment, the base 10 has the through hole 13, and the plate-like joint member 40 faces the door 1. The locking screw 13a is screwed into the locking screw hole 45 of the joint member 40 installed on the outside of the room, for example, and the head of the locking screw 13a is transparent. The pedestal 10 is fixed to the door 1 while protruding inside the hole 13 . 8(a), the head portion of the connecting screw 12a for fixing the base 10 to the door 1 overlaps with the joint member 40, and unless the joint member 40 is removed from the rotating body 20, , the connection screw 12a cannot be loosened with a screwdriver or the like, the pedestal 10 cannot be removed from the door 1 from the outside of the room, and the door handle structure cannot be disassembled.

In order to remove the joint member 40 from the rotating body 20, in the embodiment, it is necessary to slide the joint member 40 in a direction intersecting the rotation axis I0 of the rotating body 20 after loosening the fixing screw 42a. The joint member 40 is disposed so as to contact the surface of the base 10, and when the joint member 40 slides along the surface of the base 10 in a direction intersecting the rotation axis I0 of the rotating body 20, the through hole is opened. The head of locking screw 13a protruding inside 13 is engaged with the peripheral wall surface of through hole 13 to prevent the joining member 40 from sliding. As a result, the joining member 40 cannot be removed from the rotating body 20, and the connecting screw 12a cannot be loosened by a screwdriver or the like, and the door handle structure cannot be disassembled. Therefore, according to the door handle structure of the embodiment, the security can be improved.

On the other hand, on the inside of the room, for example, by not attaching the locking screw 13a to the joining member 40, if the fixing screw 42a is loosened, the joining member 40 can be moved along the surface of the pedestal 10 so as to intersect the axial direction of the rotor 20. The door handle structure can be easily disassembled. Therefore, even if completely the same parts such as the pedestal 10, the rotating body 20, the handle 30, and the joint member 40 are used for the outside and the inside of the room, for example, the outside of the room may be formed from a commercially available pan screw or the like. The door handle structure cannot be dismantled from the outside of the room by simply installing a single locking screw 13a, and crime prevention can be improved without increasing the number of parts of the door handle structure to be manufactured. Security can be improved without increasing manufacturing costs.

Further, according to the door handle structure of the embodiment, at least one connecting shaft 60 connects the pair of pedestals 10 to each other and fixes them to the door 1 . Therefore, by changing the length of the connecting shaft 60, the door handle structure can be installed on doors of various thicknesses.

As described above, the connecting screws 12a, which are shaft-shaped fasteners, connect the pair of pedestals 10 to both ends of the connecting shaft 60 from the surface of the pair of pedestals 10 opposite to the door 1, and the pair of joint members 40 Adjacent to the pedestal 10 in the direction along the rotational axis I0 of the rotating body 20, and attached to the rotating body 20 so as to be slidable in the direction intersecting the rotational axis I0 of the rotating body 20, the cover portion 46 includes a pair of pedestals. The connection screw 12a is covered on the surface of the part 10 opposite to the door 1. - 特許庁

Locking screw holes 45 are formed on the surfaces of the pair of joint members 40 on the side facing the door 1. For example, in the joint member 40 on the exterior side of the room, the locking screw 13a, which is a locking member, is a locking screw. It is mounted in the hole 45 and engages with the engaged portion of the pedestal 10 arranged on the outside of the room to lock the joint member 40 in a non-slidable manner.

Therefore, on the outside of the room, for example, even if the fixing screw 42a is loosened, the joining member 40 cannot be removed from the rotating body 20, and the connecting screw 12a cannot be loosened with a screwdriver or the like. The handle 30 cannot be removed from the connecting shaft 60, the handle 30 cannot be removed from the door 1, and it is not easy to disable the lock, thereby improving crime prevention. In addition, the base 10, rotating body 20, handle 30, and joint member 40 are made of exactly the same parts on the inside and outside of the room. 45, it is possible to prevent the joint member 40 from being removed from the rotating body 20 as described above, and two types of one part having the same function are manufactured for the inside and outside of the room. Security can be improved while avoiding an increase in the number of parts to be manufactured.

Further, as described with reference to FIGS. 1 to 8, according to the door handle structure according to the embodiment, the engaged portions of the pair of pedestals 10 are formed from the peripheral wall portions of the through holes 13, The locking screw hole 45 overlaps the through hole 13 in the direction along the rotation axis I0 of the rotating body 20, and the locking screw 13a is inserted through the through hole 13 into the locking screw hole in one of the pair of pedestals 10. 45 is installed. Therefore, the peripheral wall of the through hole 13 encloses the locking screw 13a as a locking member so that it cannot be seen from the outside. Crime prevention can be further improved.

Further, as described with reference to FIGS. 1 to 8, according to the door handle structure according to the embodiment, the locking screw hole 45 as the mounting portion for the locking member is formed of a female screw. The locking screw 13a as a locking member has a male screw portion screwed into the locking screw hole 45 and a head portion as an engaging portion that engages with the engaged portion of the pedestal 10 . Therefore, for example, a commercially available pan head screw can be used as the locking screw 13a, and crime prevention can be improved while avoiding an increase in the number of parts to be manufactured.

Further, as described with reference to FIGS. 1 to 8, the door handle structure according to the embodiment can be designed so that only the handle 30 is substantially visible from the outside when not operated. Since the handle 30 can be operated to open the door 1 by tilting the entire handle 30 with respect to the surface 1a of the door 1, the boundary line between the movable part and the fixed part does not appear outside the door handle structure. can be designed to For example, when the upper half of the surface plate portion 31 is the fixed portion and the lower half is the movable portion, the surface plate portion 31 has a boundary line between the movable portion and the fixed portion. According to the handle structure, the surface plate portion 31 can be formed from an integral plate material, so that the door handle structure can have an extremely simple design, and the design can be easily improved.

Further, as described with reference to FIGS. 1 to 8, according to the door handle structure according to the embodiment, the positioning projection 34, which is the positioning means, extends from the surface of the surface plate portion 31 facing the door 1. As shown in FIG. 8(a), the positioning protrusion 34 abuts the joining member 40 when the handle 30 is in the normal state, and positions the handle 30 at the fixed position in the normal state. Therefore, when the shape of the handle 30 is square as in the embodiment, and the inclination of the handle 30 in the direction of rotation can be recognized by a person, the handle 30 can be positioned so as not to be inclined in the direction of rotation. It is easy to improve the performance. In addition, by forming the positioning protrusion 34 into a conical shape whose diameter decreases toward the tip in the projecting direction, the inclination of the handle 30 in the rotation direction can be more reliably eliminated, and the design can be easily improved.

Another embodiment of the present invention will now be described with reference to FIG. Fig.9 (a) is a rear view which shows the handle of other embodiment. FIG.9(b) is a side view which shows the handle of other embodiment. FIG. 9(c) is a cross-sectional view taken along line EE of FIG. 9(a).
