The present application claims priority to Korean Patent Application No. 10-2012-0112306, filed on Oct. 10, 2012 in the Korean Intellectual Property Office, the entire contents of which is incorporated herein for all purposes by this reference.
1. Field of the Invention
The present invention relates to a connection structure of a door latch and a door handle base, and more particularly, to a connection structure of a door latch and a door handle base capable of obtaining coupling property and simplification of the structure by directly connecting a door latch adapter mounted at the door latch to the door handle base.
2. Description of Related Art
In general, a door module, which is mounted at a door, includes a door latch, a door latch adapter, and a door handle base.
Meanwhile, a connection structure of a door latch and a door handle base according to the prior art includes a door latch adapter 30 and a base support bracket 40 provided between a door latch 10 and a door handle base 20 so as to connect them with each other, as shown in
That is, in the connection structure of the door latch and the door handle base, the door latch adapter 30 is connected to the door latch 10, the base support bracket 40 is connected to the door handle base 20, and the door latch adapter 30 is connected to the base support bracket 40.
However, in the connection structure of the door latch and the door handle base according to the prior art, the base support bracket 40 interferes with a door frame and a door outer rail at the time of being assembled at the door, to thereby degrade assembly property.
Further, in the connection structure of the door latch and the door handle base according to the prior art, the base support bracket 40 strikes the door handle base 20 at the time of colliding with a side surface, such that the door handle base 20 allows a door handle to move, while rotating, to thereby open a door.
The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present invention are directed to providing a connection structure of a door latch and a door handle base capable of obtaining coupling property and simplification of the structure by removing a base support bracket and directly connecting a door latch adapter mounted at the door latch to the door handle base.
A connection structure of a door latch and a door handle base may include a door latch adapter mounted at the door latch, and the door handle base mounted at a door handle, wherein a coupled part formed at the door latch adapter is insertedly coupled to a coupling groove formed at the door handle base.
A pair of coupled parts is provided so as to correspond each other and may include catching jaws formed at outer sides thereof so as to be caught and supported by the coupling grooves.
The pair of coupled parts may include an inner side and an outer side inclined with respect to a longitudinal axis of the coupled parts.
A pair of coupling grooves is formed and may have the pair of coupled parts each inserted thereinto.
A reinforcement member is formed between the coupling grooves.
The pair of coupled parts may have elastic force in a direction pushing away each other.
The coupling groove is formed at a front of a support member formed at the door handle base and the support member is provided with a moving space formed therein so that the coupled part insertedly coupled to the coupling groove moves in a length direction of the coupled part.
The moving space communicates with the coupling groove.
The door latch adapter and the door handle base are connected to each other by a connection member.

Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that the present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
In a connection structure of a door latch and a door handle base according to the present invention, a door latch adapter mounted at the door latch is connected to the door handle base mounted at a door handle through a coupled part and a coupling groove, thereby increasing assembly property of the door latch and the door handle base and simplification of the structure.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that they can be easily practiced by those skilled in the art to which the present invention pertains. However, the present invention may be modified in various different ways and is not limited to the exemplary embodiments provided in the present description. In the accompanying drawings, portions unrelated to the description will be omitted in order to obviously describe the present invention, and similar reference numerals will be used to describe similar portions throughout the present specification.
A connection structure of a door latch and a door handle base according to an exemplary embodiment of the present invention includes a door latch adapter 200 mounted at a door latch 100, and a door handle base 300 mounted at a door handle 400, as shown in
In this configuration, a coupled part and a coupling groove are each formed between the door latch adapter 200 and the door handle base 300, as shown in
For example, a coupled part 210 is formed at the door latch adapter 200 and a coupling groove 311 is formed in the door handle base 300 so as to insertedly couple the coupling part 210 thereinto.
A pair of coupled parts 210 is provided at the door latch adapter 200 so as to correspond to each other and have catching jaws 211 formed at outer sides thereof so as to be caught and supported by the coupling grooves 311.
That is, when the pair of coupled parts 210 are inserted into the coupling grooves 311 and then pulled, the catching jaws 211 of the coupled parts 210 are caught and supported by outer peripheral surfaces of the coupling grooves 311 to prevent a separation of the coupled parts 210, to thereby connect the door latch adapter 200 to the door handle base 300.
A reinforcement member 215 may be formed between the coupling grooves 311 so as to reinforce the coupling grooves 311.
Meanwhile, the pair of coupled parts 210 have an inner side and an outer side formed as inclined surfaces 212, wherein the inclined surfaces 212 guide the coupled parts 210 in the case in which the pair of coupled parts 210 are inserted into the coupling grooves 311, thereby increasing coupling property of the coupled parts 210.
Moreover, the pair of coupled parts 210 may increase areas which are mutually compressed through the inclined surfaces 212 corresponding to each other at the inner sides thereof, such that the catching jaws 211 of the coupled part 210 may be maximally matched, thereby making it possible to increase the coupling property.
Meanwhile, the pair of coupled parts 210 has elastic force in a direction pushing each other, thereby maintaining more stable fixing force through the elastic force in the case in which the pair of coupled parts 210 is insertedly coupled to the coupling grooves 311.
Meanwhile, a pair of coupling grooves 311 is formed and the pair of coupling grooves 311 include the pair of coupled parts 210 each insertedly coupled thereinto, thereby increasing the assembly property between the coupled parts 210 and the coupling grooves 311.
Meanwhile, as shown in
Meanwhile, as shown in
Therefore, in the connection structure of the door latch and the door handle base, the door latch is directly connected to the door handle base through the coupled parts and the coupling grooves without any separate brackets, thereby making it possible to obtain the assembly property and the simplification of the structure.
According to an exemplary embodiment of the present invention, the door latch adapter mounted at the door latch is connected directly to the door handle base, thereby making it possible to obtain coupling property and simplification of the structure.
For convenience in explanation and accurate definition in the appended claims, the terms “upper”, “lower”, “inner” and “outer” are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.
