Description

  The present invention relates to a door operation handle.

  As an operation handle in which an electronic component is accommodated in a hollow portion formed by connecting front and back covers, those described in Patent Documents 1 and 2 are known. In the invention described in Patent Document 1, the operation handle is formed by closing the opening formed in the handle main body (back cover) with the handle cover (front cover), and almost all the load applied to the operation handle is back. Since it is borne by the cover, it can prevent the strength or rigidity from being reduced by connecting two parts, but the connection strength of the front cover is low and the boundary between the front cover and the back cover is large on the surface. There is a problem that the degree of freedom in design is low due to exposure.

  On the other hand, Patent Document 2 is formed by fitting front and back covers. Since the front and back covers have appropriate rigidity, when a load is applied to the operation handle, appropriate strength by the front and back covers is provided. Since the sharing is performed, the overall strength can be expected, and the design problem described above can be solved.

  However, in the above-described conventional example, in order to perform appropriate strength sharing by the front and back covers, it is necessary to make the front cover into a box shape with both ends closed, and thus there is a disadvantage that the degree of freedom in design is reduced. is there. In other words, if the front cover is formed with an open end that is not connected at one end, the rigidity of the front cover is weakened. As a result, appropriate strength sharing may not be performed and the overall strength may be reduced.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a door operation handle that can increase the degree of design freedom of the front cover and has high strength as a whole.

According to the present invention, the object is
A door operation handle that is formed in a hollow shape by covering the back cover 1 with a front cover 2 made of synthetic resin,
The front and back covers 1 and 2 are formed in a thin U-shaped section or a substantially U-shaped section having side walls on both side edges, and at least one cover is passed through the other cover in the longitudinal direction and fitted over the entire length. And are connected with screws where appropriate,
In addition, at least one of the inner fitting side cover and the outer fitting side cover has one end formed as an open end, and in the connected state, a fitting recess 3 formed near both ends of the inner fitting side cover. This is achieved by providing a door operation handle in which the fitting protrusion 4 protruding from the outer fitting side cover is fitted in the longitudinal direction and the width direction.

  For the door operation handle, after the inner fitting side cover is fitted between the rising walls 6 erected on both side edges of one cover (outer fitting side cover), the front and back covers 1, 2 are connected by screws 11. When the operating force is applied to the door operation handle, if the rigidity of one cover is low, the cover with the lower rigidity is bent and the integrity of the structure of the front and back covers 1 and 2 is lost. Thereafter, since the load is borne only by the other cover, the strength of the entire operation handle is reduced.

  In the present invention, the fitting recesses 3 are formed in the vicinity of both ends of the inner fitting side cover, and the outer fitting side cover is fitted, so that structural integration can be achieved even if the rigidity of either the front or back cover is low. As a result, the strength of the entire handle, which enables the strength burden by both the front and back covers, is improved.

  Further, the fitting recess 3 and the fitting protrusion 4 are arranged at the positions where both ends of the front and back covers 1, 2 are deformed, that is, when one of them is deformed, the deformation is effectively prevented, Integration of both members can be achieved.

Furthermore, the fitting projection 4 and the fitting recess 3, in order to engage with each other also in the width direction in addition to the longitudinal direction, improved degree of integration can be achieved more improvement in strength. In this case, the fitting protrusion 4 and the fitting recess 3 can constitute a door operation handle having a stepped step 5 that is engaged in the width direction.

The lock case of the electric lock 10 can be used for a lock device in which an authentication unit for authenticating the authentication signal received by the authentication signal receiving unit 9 is stored.

  As described in Japanese Patent Application Laid-Open No. 2004-228688, the lock device in which the authentication signal receiving unit is accommodated in the operation handle (H) is mounted on the vehicle after the output from the receiving unit is drawn into the door body 14 via the harness. Some are configured to be connected to a controller such as a computer, but in this case, the wiring length becomes long, and the necessity of signal attenuation, noise intrusion countermeasures, etc. occurs.

  On the other hand, when the authentication unit is accommodated in the electric lock 10, it is possible to shorten the wiring routing length as much as possible. In particular, the operation handle (H) used in an entrance door or the like is often used to transmit the operation force to the operation handle (H) to the latch bolt 17 in the electric lock 10 directly or by a simple link device or the like. Therefore, the electric lock 10 and the operation handle (H) are often arranged close to each other, which is effective for shortening the wiring routing length.

In the operation handle (H), a biometric authentication such as a communication antenna with an authentication card of a card type authentication device using RFID, a communication antenna with a portable transmission device carried by a user, a fingerprint sensor or the like. Various devices corresponding to the authentication device to be used such as an image reading unit of the device can be accommodated.
According to the present invention,
A door operation handle that is formed in a hollow shape by covering the back cover 1 with a front cover 2 made of synthetic resin,
The front and back covers 1 and 2 are externally fitted with at least one cover to the other cover, and are connected by screwing appropriate places.
And providing a door operation handle in which, in a connected state, the fitting protrusion 4 protruding from the outer fitting side cover is fitted into the fitting recess 3 formed in the vicinity of both ends of the inner fitting side cover. Is also possible.

  According to the present invention, the strength can be increased as a whole without reducing the design freedom of the front cover.
