Handle for sliding door {KNOB FOR SLIDING DOOR}

The present invention relates to a handle for a sliding door, and more specifically, an improved sliding handle for a sliding door, which is mounted to be inserted into the sliding door to allow the door to be opened and closed while facilitating the appearance of the exposed part while responding to the thickness of the door. It's about offering.

Sliding doors are generally performed by sliding the doors of buildings, such as malls, apartments, houses, buildings, or doors installed in passages connecting indoor and indoor spaces, and opening and closing windows installed for indoor and outdoor ventilation and lighting. It means the form to do.

The handle installed on the sliding door is divided into a type that is exposed to the outside of the door and protrudes, and a type that is installed without being exposed to the outside of the door. It is installed so as not to protrude from the surface of the door.

Various types of handles for sliding doors have been developed and used, and a representative example is as follows.

Document 1, the central portion of the handle 10 is formed in the longitudinal direction of the long groove 11, the cut groove 12 formed on the outer circumferential surface of the hook groove 11, and the upper portion of the cut portion 12 In the handle of the door frame with a fastening hole 20 for inserting the fastener 21 in the lower portion,

Insertion groove 30 formed as the outer circumferential surface of the fastening hole 20, a plurality of locking grooves 31 formed at the edge of the insertion groove 30, and the insertion groove 30 is inserted into the locking groove 31 When the cover 40 is inserted into the insertion groove 30, including a cover 40 formed by protruding a plurality of locking protrusions 41 to protrude at an edge so that the surface of the cover (cover) is swung It is configured to be horizontal with the surface of the cut portion 12.

No.

Literature 1 of the prior art described above is closed with a cover so as not to expose screws or the like through the fastening hole and the fastening hole used to fix the handle embedded in the sliding door, but the cover is visually exposed. Therefore, it is difficult to maintain a beautiful finish with the entire handle.

In addition, since it is installed on one side of the sliding door alone, the height may be different when installed on both sides of the sliding door, and when the thickness of the door is thin, it is difficult to maintain a stable bonding state by bumping the recesses of the handles against each other. .

In the case of document 2, the plate spring is fixed to the deformation space formed on the upper and lower sides of the handle by screws, and when the force is pushed into the handle installation groove formed to be recessed in the sliding door, the plate spring is jammed in the reverse direction so as not to escape. Therefore, unnecessary exposure to the outside of the handle is prevented.

In this case, if the handle installation groove is not formed accurately, the plate spring cannot be jammed or cannot be inserted, making it difficult to install the handle and easily detaching after installation.

In the case of document 2, as mentioned in document 1, handles should be installed on both sides of the sliding door. It does not matter if the thickness of the sliding door is thick, but when the thickness of the sliding door is thin, each other when forming the handle installation grooves at the same position If the two handles are thicker than the thickness of the sliding door, the installation becomes difficult.

In addition, in the case of the sliding doors made of wood in both documents 1 and 2, it may be possible to apply and use them, but since they cannot be installed in sliding doors made of aluminum or plastic materials with an empty interior, the versatility is limited, so there is a disadvantage of low utilization. There are several problems, such as occurring.

Accordingly, in the present invention, the present invention was made to solve the above problems, and the base 106 is formed in the handle hole formed on the inner surface and the outer surface of the sliding door, and the recess 106 is formed so that the user's finger can enter the surface The inner and outer handles of the branches; A female coupling tube and a male coupling tube formed on the rear surface of the inner handle and the outer handle to be coupled to each other; It is provided on the water coupling pipe and coupled to the pressure-combining pipe, so that it does not deviate and includes a coupling maintaining means capable of maintaining the coupling state;

When attaching the handle to the sliding door, there is no harm to the aesthetics, and it is a simple structure, and regardless of the thickness and material of the sliding door, it is possible to mount the handle in a sturdy state, and it is possible to continuously maintain the mating state, thereby improving the quality of the handle and users It is possible to achieve the purpose of increasing convenience.

The present invention excludes the fixing means such as screws or bolts through structural changes so that the handles symmetrically installed on both sides of the sliding door can be firmly coupled to each other, so that there is no exposure of the fixing means to the outside of the handle to enhance the aesthetics. It has the effect.

In response to the thickness of the sliding door, it is possible to install without a separate gap adjustment means, and by allowing the sliding door to be installed regardless of materials such as wood, aluminum or plastic, it increases versatility and facilitates installation work. It is an invention having an effect.

The handle 100 for the sliding door to which the technology of the present invention is applied is accommodated in the handle hole 104 formed on the inner surface 102 and the outer surface 103 of the sliding door 101 and a user's finger can enter. It is provided with an inner handle 107 and an outer handle 108 having a base 106 on the surface of which the recess groove 105 is formed.

The indentation groove 105 and the base 106 constituting the inner and outer handles 107 and 108 are illustrated in a rectangular shape in the drawings of the present invention, but this is the shape and shape of the sliding door 101 or the sliding door 101 Since it will be possible to have a variety of shapes and shapes according to the type of the installation location or building, it will be natural that the present invention is not limited to the shapes illustrated in the drawings.

In addition, the material of the handle 100 for the sliding door to which the technology of the present invention is applied may be variable in accordance with the material and shape of the sliding door 101, various materials such as metal, non-ferrous metal, plastic material or wood.

On the back surface of the inner handle 107 and the outer handle 108, a pair of female coupling tubes 109 and a male coupling tube 110 are formed to insert a male coupling tube 110 into the female coupling tube 109, respectively. In order to be possible, the water coupling pipe 110 is further provided with a coupling holding means 111 so as not to be separated after being coupled to the pressure coupling pipe 109 so as to maintain the coupling state.

The diameter (D) of the female coupling tube (109), which protrudes on the back surface of the inner and outer handles (107, 108), is formed larger than the diameter (D1) of the male coupling tube (110) to insert the male coupling tube (110). To facilitate this, the length (L, L1) of the female and male coupling pipes (109,110) is less than 3 mm, the minimum coupling length (L2) that allows the female and male coupling pipes (109,110) to be inserted to maintain a stable coupling state. It should be long, and it would be desirable to have a length smaller than the thickness of the sliding door 101 (T, usually 22-42 mm).

The coupling holding means 111 forms a step 112 at the end of the male coupling tube 110, and the step 112 has a coupling plate made of an elastic material having a larger diameter than the inner diameter of the female coupling tube 109 The mounting plate 113 is fixed by placing the 113 and bending the step 112.

A plurality of tooth protrusions 114 are formed on the outer diameter portion of the coupling plate 113, and the coupling plate 113 is configured to have an inclination in the direction of the base 106 from the male coupling pipe 110, so that insertion is easy. It is made to be configured so that the tooth projections 114 are engaged in the inner diameter portion of the female coupling pipe 109 when it leaves.

As another example of the coupling holding means 111, the outer surface of the male coupling tube 110, the entrance surface 115 having a backward slope in the direction of the base 106 from the male coupling tube 110, and the entry surface 115 It may be configured by forming a plurality of engaging projections 117 formed with a locking jaw 116 at the rear end of the.

Looking at the use state of the sliding door handle 100 to which the technology of the present invention is applied as described above is as follows.

After forming the handle hole 104 on the inner surface 102 and the outer surface 103 of the sliding door 101, the inner handle 107 and the outer handle 108 are placed in the handle hole 104, and then there are dark defects. If the position of the tube 109 and the male coupling tube 110 is aligned, and the inner handle 107 and the outer handle 108 are strongly pushed, the male coupling tube 110 is inserted into the female coupling tube 109.

At the same time, the handle 100 is a sliding door 101 because the female and male coupling pipes 109 and 110 are not detached (separated) by the coupling holding means 111 provided in the male coupling pipe 110, thereby maintaining a solid coupling state. It is possible to maintain the state coupled to, the user is to be able to open and close the sliding door 101 using the handle 100.

The inner and outer handles 107 and 108 can be continuously maintained by the coupling holding means 111 in the process of being coupled to the male coupling tube 110 to the female coupling tube 109. The tooth projection 114 of the coupling plate 113 having elasticity fixed to 110) is in a backward inclined shape of the male coupling tube 110, and is easily inserted into the female coupling tube 109, but in the opposite direction It is because they are caught and do not escape.

In addition, even in the case of the engaging projection 117 formed on the outer surface of the coupling holding means 111 of the male coupling pipe 110, the insertion into the compression bonding pipe 109 by the entry surface 115 is easily made. , After being coupled, it is prevented from being separated in the opposite direction by the engaging jaw 116, so that the coupled state can be maintained.

In addition, since it is possible to correspond to the thickness of the sliding door 101 using the lengths of the female and coupling pipes 109 and 110, it is possible to apply to the sliding door 101 of various standards using one handle 100. Since the inner and outer handles 107 and 108 are combined with each other, the inner structure of the sliding door 101 is not affected, so the sliding door 101 is related to wood, metal, non-ferrous metal or synthetic resin (plastic) material. Without it, it can be used universally.

The present invention does not spoil the aesthetics when the handle is mounted on the sliding door, and it is a simple structure, and the handle can be mounted in a solid state regardless of the thickness and material of the sliding door, and it is possible to keep the combined state continuously, so the quality of the handle can be maintained. It has the advantage of increasing the convenience of users.
