Description

Detailed description of the invention

The present invention relates to a doorknob used for a door such as a partition in a room, and relates to a doorknob for changing a grip ball type doorknob to a lever type .

Partitions are used in offices to secure a space for visitors and meetings and to distinguish them from offices, and grip ball type doorknobs are generally used for these doors.

Explaining the conventional configuration of the grip ball type doorknob, reference numeral 1 denotes a door lock body, which is attached to a door (not shown). Reference numeral 1a is a slit of the rotating portion for opening and closing the lock body. Reference numeral 2 denotes a first grip ball main body mounted on the front side of the door, and 2a is a spindle portion provided so as to protrude from the grip ball main body 2 and be inserted into the slit 1a. Reference numeral 2c is a strut portion provided so as to protrude from the first grip ball main body 2.

Reference numeral 3 denotes a second grip ball body mounted on the back side of the door, and a hole portion 3a into which the spindle portion 2a is inserted through the slit 1a is provided.
Reference numeral 4 denotes a grip ball mounting plate, which is screwed to the support column portion 2c of the first grip ball main body 2 by a mounting plate fixing screw 5 for inserting the mounting hole 4a, and the first grip ball main body 2 is fixed. NS.
The second grip ball body 3 is also attached by the screw portion 4b of the grip ball mounting plate 4.

The conventional grip ball type doorknob configured as described above rotates the spindle portion 2a by rotating the grip ball body 2 or 3, and passes through the slit 1a of the rotating portion of the lock body 1. It opens and closes the lock body 1.

In addition, when using the space such as a partition, when carrying in luggage, it is necessary to hold and rotate the grip ball by hand to open and close the door with the grip ball type door knob, and when the hand is blocked by luggage, the door opens and closes. Is not easy to do, and there are increasing requests to change to the lever type.

As for the change to the lever type, a method such as replacement including the lock part or a simple method of covering the grip ball with a silicon lever has been proposed.
An example of the latter is Technical Document 1.

Jitsuto No. 30733920

However, the replacement with the lever type including the lock part described above is costly, and the one in which the silicon lever is put on the grip ball described later has a problem that the position of the lever shifts. rice field.

Further, in the above-mentioned method, there is a method in which the rotating means of the lock of the lever handle is changed in advance so as to match the lock body used for the grip ball, but the replacement work with the lever type has become easier. There are many types of lock bodies with different shapes and dimensions, and it has been a cost issue to prepare various lever handles that match the lock body of the grip ball doorknob in advance. (It was only prepared for the relatively versatile grip ball type doorknob.)

In the present invention, a drive adapter provided with a drive unit for rotating the rotating portion of the door lock body that opens and closes the lock on the front surface and a passive portion for receiving the drive operation of the lever handle on the back surface is provided between the lock body and the lever handle unit. The door lock body is sandwiched between the two, and a pair of the door locks are arranged so as to face each other.

The present invention is a driving unit for rotating the rotating portion of the door lock body to the front, respectively the drive adapter having a passive portion for receiving a driving operation of the lever handle on the back between the door lock body and lever handle unit By providing a pair of lever handle units facing each other with the door lock body in between, the lever handle unit can be manufactured in advance regardless of the rotating part of the lock body, and by using a drive adapter that matches both, it can be easily attached to the lever handle. It can be replaced at low cost.

Incidentally, the door lock as a configuration in which the ends of the spindle to be inserted into the recess of each that is provided on the front surface of the driving portion of the pair of drive adapter top Symbol configuration slit of the rotating portion of the door lock body is inserted respectively It forms the opening and closing mechanism of the main body.

In addition, by preparing a lever handle unit provided with drive pins for rotational operation engaged with the passive portion of the drive adapter, the lever handle unit of each opening and closing operation of the lock body through the drive adapter This makes it possible to provide an inexpensive and versatile lever handle unit.

Exploded perspective view of the engagement Relais bar handle type doorknob to the present invention An exploded perspective view of a conventional grip ball type doorknob

An embodiment of the present invention will be described with reference to an exploded perspective view of the lever handle type doorknob of FIG. The same parts as those in the prior art will be given the same numbers and will be described without description.

According to the figure, reference numeral 10 denotes a drive adapter, which is provided in pairs with the lock body 1 as the center and facing each other. Each of the pair of drive adapters 10 is provided with a first recess 10a on the front surface (lock body 1 side), and an end portion of a spindle 10b inserted into a slit 1a of a rotating portion of the door lock body 1 is inserted. The drive unit is composed of the first recesses 10a and the spindle 10b of each of the pair of doorknob conversion adapters 10.

Reference numeral 10c is a second recess forming a passive portion provided on the back surface of each drive adapter 10, 11 and 12 are lever handle units attached to both sides of the door, and 11a is a lever handle unit 11. It is a drive pin that is inserted and engaged with the second recess 10c (not shown) incorporated in the second recess 10c (not shown).

Similarly, a drive pin 12a (not shown) is also provided on the lever handle unit 12 side, and is inserted and engaged with the second recess 10c of the drive adapter 10 on the lever handle unit 12 side.

Reference numeral 13 is a first lever base, 15 is a second lever base, and the first lever base 13 and the second lever base 15 are attached to the door (not shown) by the first screw 14. The door lock body 1 is sandwiched and fixed.

Reference numeral 16 denotes a second screw, which fixes the lever handle unit 11 to the lever base 13 so that the drive pin 11a can rotate with the operation of the lever 11b.

Reference numeral 17 denotes a third screw for fixing the second lever base 15 to the lever handle unit 12 so that the drive pin 12a (not shown) can rotate with the operation of the lever 12b. It is a drive adapter fixing screw that integrates a pair of drive adapters 10 and a spindle 10b so as to be rotatable.

In the doorknob configured as described above, the drive adapter 10 is rotated by the drive pin 11a or 12a by rotating the lever 11b or 12b of the lever handle unit 11 or 12, and the door lock main body is rotated by the spindle 10b. The lock for opening and closing the door is released by rotating the rotating portion of 1.

As is clear from the above description, the passive portion on the back side of the drive adapter 10 can have a fixed configuration in relation to the drive pin 11a of the lever handle unit 11, but the drive portion on the front side is a door. By changing the configuration of the lock body 1 according to the relationship with the rotating portion 1a, the door knob can be simply changed by changing the drive adapter 10 according to the configuration of the door lock body 1 without changing the configuration of the lever handle unit. Can be changed from a grip ball type to a lever type.

In the above embodiment, the spindle 10b has been described as being inserted into the slit 1a of the rotating portion of the door lock body 1, but the center of the driving portion on the front side of the doorknob conversion adapter 10 is a prismatic pillar. By doing so, the movable part of the door lock body can be changed to the lever type of the grip ball type door knob with a square hole only by changing the drive adapter, and the provided lever handle unit will be versatile. It is something that can be done.
