Description

The present invention relates to a handle that can be attached to a door plate.

As a conventional handle for a general door plate, one in which screw holes are provided at both ends in contact with the door plate is known (see FIG. 7 of Patent Document 1).
The door plate is perforated with a plurality of mounting holes penetrating in the plate thickness direction at intervals substantially equal to the spacing of the screw holes of the handle, both ends of the handle are brought into contact with the surface of the door plate, and the screw holes are made into the mounting holes. The mounting is performed by screwing a bolt into the screw hole from the back side of the door plate through the mounting hole in the state of matching with.

By the way, if this kind of handle attached to the door plate is deteriorated or damaged, it needs to be replaced. If the same kind of handle can be easily obtained, there will be no problem, but the part number. It may be difficult to obtain the same type of handle because you do not know the name of the manufacturer or the manufacturer, or the production has already ended.
In such a case, other types of handles will be attached to the door plate, but it is necessary to accurately measure the pitch and diameter of the existing mounting holes and find a handle with screw holes that match it. It takes time to select a handle.

Also, if only other types of handles that do not fit the existing mounting holes are available, it is necessary to re-drill the mounting holes in the door plate so that they overlap the screw holes of the handles, but it is suitable for the thickness and material of the door plate. It is necessary to prepare a tool for drilling and then perform the drilling work accurately.

Therefore, the problem to be solved by the present invention is to provide a handle that can be attached to the door plate by using the mounting holes as they are, regardless of the size of the distance between the existing mounting holes provided in parallel with the door plate. It is a thing.

In order to solve the above-mentioned problems, the handle of the present invention is provided with a plurality of bolts, a plurality of nuts, and a handle body.
The plurality of bolts can be inserted into a plurality of mounting holes penetrating from the front surface to the back surface of the door plate so that the head is located on the back surface side of the door plate.
The plurality of nuts can be screwed into the bolt from the front side of the door plate, respectively, and the handle body can be attached to the door plate from the front side via the bolt and the nut. ..
The handle body is composed of a base portion that comes into contact with the front surface of the door plate and a handle portion that is connected to the base portion and can be gripped by a hand.
The base portion has a rail groove extending in the longitudinal direction of the base portion and opening at both end surfaces of the base portion on the contact surface with the front surface of the door plate, and inside from both side surfaces of the rail groove in the longitudinal direction. It has a pair of facing flanges that project in the direction.
Each nut has a non-uniform outer diameter, is screwed into each bolt, and has the rail groove along the longitudinal direction in a state where the parallel direction of the nut and the longitudinal direction of the base portion coincide with each other. It is rotatable between a first tilted position that can be passed through and a second tilted position that cannot be passed through.
When attaching to the door plate, when all of the parallel nuts screwed into the bolts are in the first inclined position, the nuts are inserted into the rail groove through the opening of the base portion, and the bolts are inserted. When rotated, the nuts that rotate together abut on both side surfaces of the rail groove before reaching the second inclined position, and the rotation is prevented. At the same time, the nut is pulled toward the head of the bolt by the screwing action, so that the flange of the base portion and the door plate can be sandwiched between the nut and the head of the bolt. There is.

In this way, when the handle body is attached to the door plate, as long as each nut is located in the rail groove, the attachment work can be performed regardless of the distance between the nuts in parallel, that is, the distance between the mounting holes. It will be possible.
Therefore, the existing mounting holes can be used as they are, and the handles can be attached to various door plates having different mounting hole spacings.

It is smaller than the groove width of the rail groove of the base portion, and at the first inclined position, the long axis direction of the ellipse of the nut and the longitudinal direction of the base portion coincide with each other, and at the second inclined position. It is preferable to adopt a configuration in which the minor axis direction of the ellipse of the nut and the longitudinal direction of the base portion coincide with each other.

In this way, since the outer circumference of the nut has no corners and is rounded, when it is inserted into the rail groove of the base portion or when it rotates together with the bolt in the rail groove, It can be smoothly inserted or rotated without being unintentionally caught in the rail groove.

In the handle according to the present invention, it is possible to adopt a configuration in which the handle body is fitted into openings at both ends in the longitudinal direction of the base portion and further has a cap for closing the openings.

By doing so, it is possible to prevent foreign matter or the like from entering the inside through the openings at both ends of the base portion. Further, even when the nut is loosened and the base portion shifts in the parallel direction of the nut, the cap serves as a stopper to regulate the displacement movement range of the base portion, and the handle body becomes the handle body. It is prevented from falling off from the door plate.

In the handle according to the invention, it is preferable to adopt a structure in which the base portion and the handle portion of the handle body are integrally molded.

In this way, since the number of parts constituting the handle is reduced, the manufacturing cost can be suppressed, and the construction work when attaching the handle to the door plate becomes easier.

Since the handle according to the invention is configured as described above, it is possible to attach the handle to the door plate by using the mounting holes as they are, regardless of the size of the distance between the existing mounting holes provided in parallel with the door plate. It has become possible.
