[Problems to be solved by the invention]
However, the above-described conventional door handle made of a metal material has a first problem that when the skin of the hand comes into contact with the metal surface of the door handle directly in winter, it feels cold and the touch is not good.
In addition, if the surface of the door handle is covered with a resin surface material, the skin of the hand does not come into direct contact with the metal surface, so it does not feel cold, but the resin-specific surface feels smooth. As a result, there is a second problem that the feel when grasped is not good, and the surface appearance of the resin does not give a high-class feeling.
[0004]
Furthermore, when a sheet printed with a wood grain pattern is applied to the surface of such a surface material, the appearance is better than that of the resin material alone, but the printed wood grain pattern on the surface is rubbed and disappeared by being repeatedly gripped. As a result, there is a third problem that the appearance is poor.
Accordingly, the invention described in claim 1 has been made in view of the first and second problems of the prior art described above, and the object is to directly apply the skin of the hand to the metal surface. In addition to being able to suppress contact, the inclusion of a cellulosic material eliminates the smooth feel unique to resin materials, and it has soft elasticity similar to natural wooden building materials and small thermal conductivity. In addition, the present invention is intended to provide a door handle using a door handle surface material that can give a warm and moist feel to the hand.
[0005]
In addition, the invention according to claim 1 is to provide a door handle that uses a door handle surface material that can exhibit a wood grain pattern with little variation in product quality without taking time and has a good appearance. It is what.
The invention described in claim 1 has been made in view of the third problem of the prior art described above, and the object is to make the skin of the hand directly contact the metal surface. As well as being able to suppress this, the cellulosic material is contained, so there is no smooth feel peculiar to resin materials, it has soft elasticity similar to natural wooden building materials and a small thermal conductivity, It is intended to provide a door handle that can give a warm and moist feel to the hand.
[0006]
In addition to this, the invention according to claim 1 specifies the specific shape of the door handle, and provides a door handle with a simple structure, easy to grip with the hand, ensuring strength and good grip feeling. It is something to try.
[0007]
In addition to this, the invention according to claim 1 is to provide a door handle capable of ensuring the fixing of the door handle surface material and the door handle core material.
[0008]
[Means for Solving the Problems]
The present invention is for achieving the above-described object.
The invention according to claim 1 is a substantially L-shaped door handle (10) that protrudes from the surface of the door and can be grasped by a hand to open and close the door, and is a door handle core made of metal. comprising a timber and a door handle surface material covering the surface of the portion gripped by the hand of the door handle core (30) (20), door handle core (30) protrudes from the door surface in the counter-door side base portion (40), grip which can be gripped portion by hand extends substantially parallel to the front end from the door surface of the proximal end portion (40) and (50), the tip of the grip portion (50) And an elbow core material (32) fixed by a fixing pin (33) , the grip portion (50) includes a columnar portion (51) , and the door handle surface material (20) is made of resin and cellulose. a fine powder of the material while being formed of a composition composed primarily made comprises a cylindrical tubular portion capable fit around the (21) of the columnar portion (51), de Gripping portion of the handle core (30) cylindrical portion (50) and (51), between the door handle surface material (20) cylindrical portion (21), the door handle surface material (20) is a door handle core with projections projecting in the longitudinal direction around from one side of the surface against rotation towards the other side of (30) (22), the positioned surface of the other side ridge (22 ) is engaging groove (31) and is formed to engage the cylindrical portion of the door handle surface material (20) (21), in a state where fitted around the columnar portion (51), said grip portion ( characterized in that it is interposed between the 50) and the elbow core (32).
