Description

[Detailed description of the invention] This invention relates to a handle that is attached to indoor fittings, etc.

In order to facilitate the installation and removal work, the inventor of the present application placed a cylindrical pull body having a projecting piece protruding in the outer circumferential direction so that the protrusion of the pull body was placed in the circumferential direction of the inner circumferential wall embedded in a shoji etc. He first devised a handle for indoor fittings, etc., which was attached to a cylindrical adapter with a locking shelf for locking the pieces, and published it as Utility Model Application No. 124215 (1982) (Japanese Utility Model Publication No. 58-29749). I applied.

What required further improvement in such pulls was the gap created between the outer circumferential surface of the pull body and the inner circumferential surface of the adapter, which caused the pull body to wobble when touching the pull body to open or close the shoji. Not only does it not feel good, but the rattling is exacerbated and the installation becomes unstable. Furthermore, since the projecting piece of the pull body is simply locked to the locking shelf of the adapter, the pull body easily comes off from the adapter.

As mentioned above, this invention is a further improvement of the previously filed application, and it has a good feel without rattling in the pull body, and it can be installed stably, while also being difficult to remove for indoor fittings. The purpose is to provide.

Next, the invention will be explained in detail based on the embodiment shown in the figures.

In the figure, 1 is a pull main body, and 2 is an adapter, and the pull main body 1 and the adapter 2 constitute a pull handle A of an indoor fitting or the like.

The pull main body 1 has a cylindrical body 11 whose one end is sealed by a bottom wall 12, and a collar 13 is formed on the outer periphery of the other end. A substantially triangular convex surface 14 is formed protrudingly on the side opposite to the collar 13 of the bottom wall 12, and a plate spring-shaped protrusion 15 protrudes outward from the outer peripheral surface of the cylindrical body 11 from three sides of the substantially triangular convex surface 14. is formed. In the embodiment, three protrusions 15 are formed at 120 degree intervals. Since the projecting piece 15 projects horizontally from the convex surface 14 and has a gap formed between it and the outer surface of the bottom wall 12, the projecting piece 15 has elasticity so that its tip can be bent in the axial direction of the cylindrical body 11.

A protrusion 3 protruding in the radial direction is formed on the outer peripheral surface of the cylindrical body 11 of the pull main body 1. In the embodiment, the projection 3 corresponds to the projection 15 on the cylindrical body 11 that is closer to the collar 13 in the axial direction of the cylindrical body 11 than the projection 15.
formed on the outer peripheral surface.

The adapter 2 has a cylindrical shape, and its inner diameter is approximately the same as the outer diameter of the cylindrical body 11 of the pull body 1.
It is formed slightly large enough to be easily inserted. In the embodiment, the adapter 2 has the other end sealed by the bottom wall 21 in order to fit the pull body 1 only at one end, but it is also possible to use an adapter 2 configured to fit the pull body 1 from both ends.

A locking portion 22 for locking the protrusion 15 of the pull main body 1 in the circumferential direction is formed on the inner circumferential surface of the adapter 2. That is, the bottom wall 21 of the adapter 2 corresponds to the protruding piece 15 of the pull body 1 on the inner peripheral wall of the adapter 2.
An insertion groove 23 is formed in the axial direction from the opposite end.
A locking hole 24 is bored adjacent to this insertion groove 23 . A tapered guide portion 25 that gradually approaches the bottom wall 21 from the insertion groove 23 side toward the other end side is formed on the inner peripheral surface of the locking hole 24 on the opposite side to the bottom wall 21 . A locking portion 22 is formed at the terminal end of.

The pull main body 1 configured as above is connected to the adapter 2.
When fitting into the shoji, the adapter 2 is embedded in the core of the shoji, and the cylindrical body 11 of the pull main body 1 is inserted into the adapter 2 from the projecting piece 15 side. The protruding piece 15 is the adapter 2
is inserted into the insertion groove 23 of the adapter 2, and rotated in the circumferential direction toward the locking hole 24 while moving the pull body 1 in the axial direction of the adapter 2.

Along with this rotation, the projecting piece 15 of the pull main body 1 is guided by the guiding part 25 of the locking hole 24 and moves toward the bottom wall 21, and eventually locks in the locking part 22 and the adapter 2
The fitting of the pull main body 1 into the handle body is completed.

At this time, the protrusion 3 formed on the outer periphery of the cylindrical body 11 of the pull main body 1 presses against the inner circumferential surface of the adapter 2 to fill the gap between the pull main body 1 and the adapter 2.
In contrast, the pull main body 1 is firmly fixed without wobbling.

Although this invention has the above-described configuration, it can also be adopted in other shapes in which the pull body 1 is divided. (Figs. 6 to 8) That is, the pull main body 1 is divided into a cylindrical body 11, a bottom plate 12, and a collar 13.
A locking collar 16 is formed on the outer periphery of one end of the cylindrical body 11, and a decorative collar 13 can be locked thereon. Notches 17 are formed on three sides of the other end of the cylindrical body 11 in the axial direction at 120 degree intervals, and locking grooves 18 are formed in the inner peripheral surface of the cylindrical body 11 in correspondence with the notches 17.

The bottom plate 12 is disc-shaped and has a locking groove 1 of the cylindrical body 11.
8, and has protruding pieces 19 formed on three sides corresponding to the notches 17, and the protruding pieces 19
A protrusion 3 protruding from the outer peripheral surface of the bottom plate is formed at a position below the tip of the bottom plate.

This bottom plate 12 is pressed against the cylindrical body 11 and is locked into the locking groove 18 of the cylindrical body 11 in a snap manner, and the protruding piece 19 is fitted into the notch 17 to attach the bottom plate 12 to the cylindrical body 11. Install.

The protrusion 3 protrudes outward from the outer peripheral surface of the cylindrical body 11, and the pull body 1 combined in this way
If it is fitted into the adapter 2 in the manner described above, the protrusion 3 will come into pressure contact with the inner peripheral surface of the adapter 2, and the pull main body 1 will be firmly fitted into the adapter 2 without wobbling.

In the above embodiment, the protrusion 3 was formed to protrude outward from the outer peripheral surface of the cylindrical body 11 of the pull main body 1.
The same effect can be obtained even if the protrusion 3 is formed on the inner peripheral surface of the adapter 2, or even when the protrusion 3 is formed on both the cylindrical body 11 and the adapter 2.

However, in either case, when fitted, the protrusion 3
is brought into pressure contact with the facing peripheral surface near the protruding piece 15 of the pull main body 1.

Furthermore, when the pull body 1 is fitted into the adapter 2, the opposing surfaces that the protrusions 3 come into contact with are raised in advance, so that the protrusions 3 are more strongly pressed against the opposing surfaces, and the pull body 1 and the adapter 2 are more tightly connected. It is also possible to provide a firm fit.

This invention has the above-mentioned configuration, and since the leaf spring-like protrusion formed on the pull body is engaged with the locking part of the adapter and assembled, it is possible to prevent the pull body and the adapter from shaking in the direction of combination. This can be achieved by making the protrusion into a leaf spring shape and applying a strong attractive elasticity.

Furthermore, by utilizing the elasticity of the projecting piece, the fitting between the main body of the handle and the adapter can be carried out easily and firmly even if there is some error in the thickness of the sliding door.

Since the protrusions are formed on the outer circumferential surface of the pull body or the inner circumferential surface of the adapter, when the pull body is fitted onto the adapter, the protrusions come into pressure contact with the opposing circumferential surfaces, making it possible to firmly fit the pull body onto the adapter. When opening or closing a shoji screen or the like by touching the handle, the handle does not rattle and does not give an unpleasant feeling. Further, since the protrusion is in pressure contact with the circumferential surface, the pull main body does not freely rotate within the adapter, so it does not easily separate from the adapter.

Since the protrusion comes into pressure contact with the opposing peripheral surface near the protrusion of the pull main body, the wobbling in the vicinity of the protrusion is minimized, making it difficult for the protrusion to separate from the locking portion.

To prevent wobbling, a protrusion is provided separately from the protrusion, so the protrusion does not interfere with the locking of the protrusion.
