Description

[Detailed Description of the Invention] The present invention relates to a handle that is attached to indoor fittings, etc.

Usually, pulls are attached to indoor fittings with nails, screws, etc.
If this is done, it becomes troublesome to attach and remove the handle, making it difficult to replace the handle.

Therefore, as shown in Japanese Utility Model Application Publication No. 51-18049, dowels are formed so that the front pull body and the back pull body can be fitted together, and have serrations that mesh and connect with each other. A handle has been proposed that is inserted into a mounting hole from the front and back and rotated in opposite directions to engage and connect the dowels with each other.

However, with this structure, the dowels formed on the front and back pull bodies are interlocked and connected, so the front and back pull bodies have different shapes.

For this reason, the number of parts is large and inventory management becomes troublesome.

The present invention was developed in view of the above circumstances, and its purpose is to enable easy removal and installation without using nails, screws, etc., and to reduce the number of parts by making the front pull body and the back pull body the same shape. To provide a handle for indoor fittings etc. that facilitates inventory management.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a front pull main body 1, a back pull main body 2, and an adapter 3. The bottom wall 4 is integrally formed with protrusions 7 that protrude outward from the outer circumferential surface of the cylindrical body 5 at intervals of 120 degrees in the circumferential direction.

The backside pull main body 2 has a shape in which a collar 10 is integrally formed on a cylindrical body 9 having a bottom wall 8, and the bottom wall 8 has protrusions 11 projecting outward from the outer peripheral surface of the cylindrical body 9 at intervals of 120 degrees in the circumferential direction. It is integrally formed with the front puller main body 1 and has the same shape.

The adapter 3 has a larger diameter than the cylindrical bodies 5 and 9 and has a larger diameter than the flange 6.
, 10, and has a cylindrical shape having a predetermined length and a diameter smaller than that of the projections 7, 10, and portions 12 of the peripheral wall thereof spaced apart by 120 degrees in the circumferential direction are curved outward in a substantially semicircular shape and protrude outwards to form the protrusions 7, 10. 11 are respectively formed, and the side groove 14 and the other side groove 15 are spaced apart in the length direction so as to open into each outward recess 13, that is, the length Each side groove 14 is inclined inwardly so that one end 14a opening into the outward recess 13 is located on the outer side in the length direction than the other side 14b. However, each of the other side grooves 15 is inclined inward such that one end 15a opening into the outward recess 13 is positioned further outward in the length direction than the other end 15b.

However, in order to attach the handle to indoor fittings, etc., as shown in Figures 4 and 5, insert adapter 3 into the mounting hole B of indoor fitting A.
, insert the front and back pull bodies 1 and 2 into the adapter 3 from the front and back surfaces a and b of the indoor fitting A, position each protrusion 7 and 11 so that they face the outward recess 13 of the adapter 3, and then insert each protrusion 7. , 11 are fitted into the outward recess 13, respectively.

As a result, each protrusion 7 of the front side pull body 1 is at the same position in the length direction as one end 14a of the one side groove 14, and each protrusion 11 of the back side pull body 2 is at the same position as one end 15a of the other side groove 15 in the length direction. position.

In this state, rotate the front and back pull bodies 1 and 2 clockwise to move the protrusions 7 and 11 along the one side groove 14 and the other side groove 15 toward the other ends 14b and 15b and engage them. The back side pull bodies 1 and 2 are connected via the protrusions 7 and 11, one side groove 14 and the other side groove 15 of the adapter 3, and can be attached to the indoor fitting A.

At this time, since the one side gutter 14 and the other side gutter 15 are inclined inward, the front and back pull bodies 1 and 2 are pulled together, and the flanges 6 and 10 are brought into close contact with both the front and back surfaces a and b of the indoor fitting A, The handle is securely installed.

In addition, if you want to remove the handle, you can operate it in the opposite direction as described above.

In addition, as shown in FIG. 6, the adapter 3 is made by rolling a corrugated plate into an annular shape and inserting it into the mounting hole B. At the same time, the one side groove 14 and the other side groove 15 may be formed in an arbitrary portion in the same manner as described above.

Further, as shown in FIGS. 7 and 8, the adapter 3 has a recess 2o extending in the circumferential direction in the central portion in the length direction, and is continuous with both circumferential end walls 20a and 20b of this recess 20. Notches 21 and 22 that serve as recesses into which the projections 7 and 11 fit
The ends of the longitudinal side walls 20c and 20d of the recess 20 are each inclined in the longitudinal direction, and each notch 21, 22 is provided with a front and back side handle. The front and back pull bodies 1, 2 may be connected to the adapter 3 by fitting the protrusions 7, 11 of the main bodies 1, 2 and then rotating them in the circumferential direction to engage the both side walls 20c, 20d.

In other words, the side walls 20C and 20d of the recess 20 constitute the negative side groove 14 and the other side groove 15 in which the projections 7 and 11 engage.

The present invention is as described above, and the front and back pull bodies 1 and 2 are fitted into the adapter 3 so that the protrusions are in the same position as the ends of one side groove and the other side groove. The handle can be attached to indoor fittings, etc. by rotating and engaging the protrusions with one side groove and the other side groove.

Therefore, the handle can be easily removed and attached, and the handle can be easily replaced.

Furthermore, the front and back pull bodies 1 and 2 can be made to have the same shape, reducing the number of parts and making inventory management easier.
