Description

  The present invention relates to an indoor door lever handle, and in particular, the shade or brightness of the colored color in the grip bar changes according to the direction of the light hitting it or the direction of viewing it, and has a high tone (high quality). It is devised to produce a dynamic decoration effect that never gets tired.

  An indoor door lever handle has a bracket that is attached to the door and operates a latch bolt, and a grip bar of a fixed length that extends from the head of the mounting bracket into a substantially L shape and extends along the door. It is a common practice.

Among various patent documents proposed to give up the decorative effect of the grip bar, the invention of Japanese Patent Laid-Open No. 2000-356053 employs a transparent or translucent cylinder as the grip bar (grip body). The cylindrical body is considered to be a known technique that is most similar to the present invention in that it has a convex lens effect.
JP 2000-356053 A JP-A-11-81752

  However, in the configuration shown in the first and second embodiments (FIGS. 1 to 5) of the invention of the above Japanese Patent Laid-Open No. 2000-356053, a transparent or translucent cylinder (6) as a gripping body and its cylinder ( A flexible decorative sheet (5) such as a separate synthetic resin film, cloth or paper on which an appropriate pattern (13) is printed is prepared in addition to the shaft (4) which is the core of the gripping body (6). In addition, this must be rounded so that the pattern (13) is on the front side and inserted and set into the cylinder (gripping body) (6).

  In this regard, when the flexible decorative sheet (5) is a cloth, the surface of the flexible decorative sheet (5) can be rolled into the cylinder (gripping body) (6) and inserted into the cylinder (gripping body) (6). It is difficult to be in close contact with the inner surface, and the accuracy and stability of the inserted set state are inferior.

  Further, in order to prevent the pattern (13) of the decorative sheet (5) from being concealed, both ends of the cylindrical body (gripping body) (6) are attached by a pair of locking rings (18) (19). The handle body (3) and the grip end (7) need to be fixed and maintained. A pair of locking rings (18) and (19) and the grip end (7) are also indispensable components. As the number of assembly parts increases and the assembly work becomes complicated, the mass production effect of the lever handle (handle member) for the door cannot be maximized and occurs on the surface of the grip bar (grip body). The stepped portion may give a sense of incongruity in gripping use.

  In addition, the pattern (13) printed on the decorative sheet (5) is seen through from the outside of the transparent or translucent cylinder (grip body) (6), and is selected in advance. Since the pattern (13) itself is merely a decorative effect, even if the pattern (13) is lifted and enlarged by the convex lens function of the cylinder (grip body) (6), this The interest of the pattern (13) does not change depending on the direction of the light hitting or the direction of viewing it, and only a static and monotonous decoration effect that everyone can get tired of can be obtained. The universality that nobody gets tired of, and a high-class (luxurious) novel decoration effect that is compatible with the interior materials and doors of the building cannot be produced.

  And about such a decorative effect rich in interest, the core material (10) and the pair of decorative bodies (5a) and (5b) and the pair of gripping bodies (6a) and (6b) are made of metal with corresponding irregular cross sections. As a manufactured assembly part, a third embodiment (FIG. 6, FIG. 6), in which a pair of decorative bodies (5a) (5b) and grip bodies (6a) (6b) is sequentially attached and integrated to the core (20). 7), the separate decorative sheet (5) of the first and second embodiments and the separate decorative body (5a) (5b) of the third embodiment are omitted, and the gripping bodies (6a) (6b) are omitted. In the configuration of the fourth embodiment (FIGS. 8 and 9) in which the decorative layers (23a) and (23b) with the pattern (13) are formed by painting or plating on the inner surface of).

  SUMMARY OF THE INVENTION The present invention aims to solve such problems, and in order to achieve the object, in claim 1, a mounting bracket for an indoor door and a fixed extension extending from the head of the mounting bracket along the door. In the door lever handle with a length grip bar,

The mounting bracket is shaped into a round prismatic shape whose head is an arc convex curved surface,

The grip bar is divided into a core rod and a separate decorative cover, and the core rod is made of a metal such as stainless steel or aluminum alloy, and the head has an arc convex curved surface that is flush with the arc convex curved surface of the mounting bracket. While shaped as a rectangular bar with a rectangular cross section, it is molded integrally with its mounting bracket,

The decorative cover is integrally molded from a light-transmitting synthetic resin containing a color pigment into a round bar shape having an insertion groove having a U-shaped cross section corresponding to the core rod, and extending.

The flat three sides except for the arc convex curved surface of the core rod, which is covered by the insertion fitting of the insertion groove in the decorative cover, are made of silver metallic tone or gold metallic tone by surface treatment such as plating, painting, vacuum deposition, etc. Finish as a light reflecting surface,

Depending on the direction of the light incident on the light reflecting surface of the square bar-shaped core rod from the round bar-shaped decorative cover of the grip bar and the direction of viewing the same, the shade or brightness of the colored color in the decorative cover may change by itself. It is characterized by having decided.

Further, in claim 2, an arc-shaped curved piece for preventing a decorative cover from coming off is provided almost only symmetrically with the arc-shaped curved surface of the head, only on the projecting tip portion of the square-shaped core rod,

A concave step surface to be fitted to the arc-shaped convex piece of the core rod is formed corresponding to the groove bottom surface of the U-shaped insertion groove in the cross section of the decorative cover,

The insertion groove of the decorative cover is inserted and fitted from the bottom side of the core rod, and the decorative cover is assembled and integrated with a grip bar that forms an overall round bar shape with the core rod by a plurality of fixing screws. It is characterized by.

According to the said structure of Claim 1, the grip bar of the lever handle for doors consists of a rigid metal core rod, and the separate synthetic resin decorative cover which coat | covers this, The core rod is attached to a door. Since it is formed integrally with the mounting bracket, there is an effect that sufficient durability strength as a lever handle can be secured.

Moreover, the inner surface of the metallic core covered with the decorative cover is finished as a silver metallic or gold metallic light reflecting surface, while the decorative cover contains a light pigment. Since the synthetic resin is integrally formed in a round bar shape, depending on the direction of the light hitting the grip bar during use and the direction of viewing it, the shade or brightness of the colored color in the decorative cover is The light reflecting action of the light reflecting surface from the inside changes itself, and in combination with the convex lens function of the round bar-shaped decorative cover, an elegant decoration effect rich in excitement can be obtained.

Also, the configuration for obtaining such a decoration effect does not require any special decoration sheet provided in the opening Japanese Patent Application Laid-Open No. 2000-356053 or the troublesome insertion and setting work.

In this respect, the decoration effect of the invention of Japanese Patent Laid-Open No. 2000-356053 is a static one of the pattern itself printed on the decoration sheet. Therefore, unless the decoration sheet is replaced, a different decoration effect cannot be obtained. In the configuration of the present invention, even if the decorative cover is not replaced, the colored color of the decorative cover is dark (dark) or light (bright) depending on the direction of light incident on the light reflecting surface of the core rod and the direction of viewing the light. It is possible to produce a dynamic decoration effect that changes itself and interests.

Furthermore, the core bar of the grip bar has a rectangular bar shape with a rectangular cross section, and the three flat sides to be covered with the decorative cover are surface-treated as light reflecting surfaces in silver metallic tone or gold metallic tone. Because the decorative cover is shaped like a round bar that can function as a convex lens, the combination of a square bar-shaped core bar and a round bar-shaped decorative cover, so to speak, is increasingly complimenting the decorative effect of changing the above shade or brightness. Can.

If the construction of claim 2 is adopted, the core bar of the grip bar and its decorative cover can be assembled and integrated into a uniform round bar shape over the entire surface, which is useful for safety in gripping use, There is also an advantage that a design accent effect can be given by using the surface exposed from the cross-sectional U-shaped insertion groove of the decorative cover as a muscular bone extending along the longitudinal direction of the grip bar.

In addition, by inserting and fitting the arc-shaped convex piece of the core rod and the concave step surface of the decorative cover, it is possible to prevent the decorative cover from coming out along the longitudinal direction of the core rod, and the arc-shaped convex piece of the core rod. In other words, as a centering guide, the U-shaped insertion groove of the decorative cover can be properly and smoothly inserted and fitted into the core bar along this, which helps to improve the assembling workability.

Hereinafter, specific configurations of the present invention will be described in detail with reference to the drawings. First, FIGS. 1 to 12 show a first embodiment of a door lever handle (A) according to the present invention.
