Description

Rotatory Doorknobs Having Members For Preventing Careless Pressing}

The present invention relates to a rotary door handle of a swing door for use indoors, and more specifically, because a specific shape of a pressing member is installed on a rotating shaft including a conventional bundle of keys, such as walls and furniture due to frequent opening and closing of doors. The present invention relates to a rotary door handle equipped with a pressure preventing member that prevents the door from being abnormally locked due to a force of the lock button being pressed by a shock of the child or a child's playful or unknowingly pressing the lock button.

Unlike past hanoks, the entrance doors and interior doors of many residential homes and offices now use more sliding doors than sliding doors. This is a sliding door in terms of aesthetic effect, ease of use, and stability to protect against outside intrusion. Because it is superior to this sliding door.

In general, such a swinging door handle can be divided into a cylindrical rotary type and a stick type operated up, down, left and right, and such rotary door handles and stick-type door handles are installed on the inner and outer sides of the door, respectively, the lock button on the interior side The door can be locked using the lock and the handle can be rotated to open the door, and the door can be locked and opened using the key.

However, the excellent swing door in terms of aesthetic effect, ease of use and stability can be forcibly pressed by the lock button due to the impact of furniture and the like on the wall and the narrow space that is in contact with the door due to frequent rotation of the door, and open the door. In the summer and fall of life, the door is abnormally locked due to the influence of wind, children's mischief or unconsciously pressing the lock button.

If the door is abnormally locked due to the above reasons, most of the keys will be locked because the door stored in the room is locked a lot of distress.

Therefore, in order to prevent the abnormal operation of the swing door, most users conventionally use a cover equipped with a thick cloth buffer buffer on the handle of the lock button, or insert a bracket between the door and the door frame to prevent the door from being closed or outdoors. A key was inserted into the door handle.

However, the above methods are only temporary measures, especially in families with children, inadvertent children can take off the cushion cover and remove the keys, and the frequent use of swing doors can easily cause cramps to achieve their original purpose. You will not be able to.

Therefore, the present invention aims to solve such problems of the prior art and technical problems that have been requested in the past.

In other words, the object of the present invention is to use a lock preventing member configured to be easily fastened to a rotary door handle that is frequently used in a conventional swing door, and when the lock button is arbitrarily operated, there is a high possibility that the swing door is abnormally locked as described above. It is to provide a rotary door handle provided with a pressing preventing member, which prevents this by manipulation, and otherwise enables the same operation as a general rotary door handle.

Rotating door handle equipped with a pressing member of the present invention for achieving this purpose,

In the rotary door handle, which comprises a key bundle, a key bundle rotating shaft, a symmetrical handle, a locking button on one handle, and a key groove on the other.

A cylindrical body rotatably mounted to the key bundle rotation shaft;

A long axis extending from the cylindrical body toward the locking button mounting handle portion, the end of the long axis being more elastically curved in the direction of the central axis than the cylindrical body; And

And a pressing preventing member, which is formed of a protrusion formed at a position corresponding to the hole of the rotating shaft in the direction of the central axis from the long axis.

Therefore, the push lock member equipped with the push lock member of the present invention is separated into a portion including a key bundle and a rotating shaft and a handle portion equipped with a lock button, and the push prevention member of the structure is inserted into the rotary shaft, When the handle portion is assembled, the pressing preventing member is positioned on the axis of rotation between the key bundle and the handle portion. When the pressing preventing member is rotated so that the protruding portion on the long shaft is inserted into the hole of the rotating shaft, it is impossible to press the locking button on the handle portion, thereby preventing the arbitrary locking. In some cases, when the pressing preventing member is rotated to its original position so that the protruding portion on the long axis is separated from the hole of the rotating shaft, the locking button of the handle portion can be used as in the original function.

Hereinafter, with reference to the drawings will be described in more detail the rotary door handle of the push preventing member of the present invention, but the scope of the present invention is not limited thereto.

1 shows a portion of a conventional rotary door handle. The rotary door handle 100, the cylindrical key bundle 110 and its rotary shaft 120 is integrally assembled in the cross-section, and the handle is symmetrically assembled to the left and right sides thereof. As shown in FIG. 1, the left and right handle portions are configured by a handle portion 130 on which the lock button 140 is mounted and a handle portion (not shown) on which the key groove is mounted. Rotating shaft 120 has a screw thread 122 is formed on the left and right sides of the key bundle 110 to be fastened to a sliding door (not shown). There is a separation hole 124 on the rotation shaft 120 toward the handle 130, the handle 130 can be easily separated using a long and thin tool that can be inserted into the separation hole 124.

2 is a front view of a state in which the handle 130 is separated as described above. Rotating shaft 120 is a multi-stage symmetry around the key bundle (110). That is, the diameter of the cylinder becomes smaller as it goes to both ends. When the handle 130 is fastened, the rotating shaft hole 126 is located on the rotating shaft 120 that is covered by it, the axis of the locking button 140 when the locking button 140 is pressed (not shown) This movement can be observed through the rotating shaft hole (126).

In Figure 3, as shown in Figure 2 is shown the state in which the pressing member 200 of the present invention is mounted on the rotating shaft 120 in a state in which the handle 130 is separated. The pressing preventing member 200 is a cylindrical body 210 that can be rotatably fastened to the key bundle rotation shaft 120, the long shaft 220 extending from the cylindrical body 210 toward the handle 130, and the rotary shaft hole And a protrusion 230 (indicated by a dotted line) protruding from the long axis 220 toward the center of the rotational shaft 120 at a position corresponding to 126. The pressing preventing member 200 can be easily mounted by a simple process of inserting into the rotating shaft 120 in a state in which the handle 130 is separated as shown in FIG.

In the conventional door handle, when assembling the handle 130 to the rotary shaft 120, there is almost no gap in the space where the handle 130 and the rotary shaft 120 is assembled, the pressing preventing member 200 In the attached state, assembly is impossible. Accordingly, the long axis 220 of the pressing preventing member 200 may be inserted, and a space capable of moving up and down by a predetermined distance about the rotating shaft 120 in the inserted state should exist on the handle 130. . Therefore, as shown in the figure, the handle portion 130 of the present invention is drilled the handle portion hole 132 into which the long axis 220 can be inserted.

4 is a view showing a state in which the handle 130 is assembled in a state in which the pressing preventing member 200 is mounted. The part exposed to the outside in the state in which the rotary door handle 100 is mounted on the door (not shown), only a portion outside the portion indicated by the dotted line in the figure, that is, the handle 130 and the part of the rotating shaft 120 Exposed to the door. In the case of the pressing preventing member 200, the entire cylindrical body 210 and a part of the long axis 220 is exposed. Thus, by rotating the cylindrical body 210 exposed to the outside in this way, the operation of the pressing member 200, that is, the pressing prevention mode and the release mode can be set. Moreover, in the general use of the rotary door handle 100, the user does not easily reach the pressing preventing member 200 does not interfere with the use at all.

5 and 6 show a more detailed structure of the pressing preventing member 200. When viewed from the opposite direction of FIG. 3 (FIG. 5), the protrusion 230 appears inside the end of the long axis 220. The long axis 220 is elastically bent in the central axis direction when viewed horizontally (FIG. 6). Therefore, when the pressing preventing member 200 is in the pressing preventing mode in a state in which it is mounted on the rotating shaft 120 (see FIG. 3), the long shaft 220 keeps the curved state while the protrusion 230 rotates the rotating shaft hole 126 (FIG. 3). Will be inserted). On the other hand, when the pressing preventing member 200 is in the unwinding mode in a state in which it is mounted on the rotary shaft 120, the long axis 220 is maintained in a horizontal state while the protrusion 230 is located on the outer surface of the rotary shaft 120 .

In the unwinding mode, since the long axis 220, which was originally bent, is forcibly kept horizontal, an elastic restoring force is generated. Therefore, when the protrusion 230 moves to the rotary shaft hole 126 by the rotation of the pressing preventing member 200, the protrusion 230 is forcibly inserted into the rotary shaft hole 126 by the recovery force of the long shaft 220. do. In particular, in the unwinding mode, since the restoring force is present on the long axis 220, a relatively large frictional force exists between the protrusion 230 and the outer surface of the rotating shaft 120. Thus, by preventing the so-called "idle rotation" in which the cylindrical body 210 freely rotates even when no force is applied on the outer surface of the rotation shaft 120, an artificial operation is required at the time of switching between the release mode and the anti-press mode. do.

When the protrusion 230 is positioned on the outer surface of the rotation shaft 120 in the unwinding mode, the long shaft 220 does not necessarily need to be horizontal, and may have a structure capable of imparting a restoring force. "Z" in FIG. 6 represents the vertical movement distance of the long axis 220, which is related to the restoring force. Therefore, the restoring force is proportional to the elastic force of the long axis 220 material and the vertical movement distance Z.

7 is a side view of the pressing preventing member 200, when viewed from the side, a projection 230 is formed on the lower surface of the long axis 220 extending from the top of the cylindrical body 210 to the front side . In order to facilitate the rotation process of the pressing preventing member 200, it is preferable to form an unevenness on the outer surface of the main body 210 to increase the friction force.

Those skilled in the art to which the present invention pertains, various modifications and applications will be possible within the scope of the present invention with reference to the above contents.

The revolving door handle mounted on the swing door has excellent aesthetic effect, ease of use and stability, such as the impact of the wall, furniture, etc. contacting the door due to the playful or involuntary pressing of the lock button and frequent rotation of the door. As a result, abnormal locking of the door may occur, such as the locking button being forcibly pressed. However, the rotatable door handle of the present invention prevents the problem of abnormally locking the door due to the above causes and the like, so that it is possible to achieve convenient use by simple operation while achieving good management and safe use of the locking device.
