Abstract

A handle, for example a door handle, is provided comprising a handle portion (10), a base portion (11), and spindle (12). The handle portion (10) is rotatable with respect to the base portion (11) but is held in position against the base (portion11) by trapping the base portion (11) between a projecting part and the spindle (12) and the handle portion (10).

Description

Handle

The present invention relates to handle, for example be used for the handle of window and door.

This handle generally comprises in base part (base portion) and goes up the rotatable handle part.In use, base part is attached to window or door, and handle portion is provided with axle, and axle passes base part and enters into operating mechanism, makes handle with respect to the rotary manipulation mechanism of base part and open or close window or door.

A kind of handle of canonical form is through making so that axle is fixed in the handle around the end molded handles of axle.Handle has the outstanding axle collar of threaded shaft, and the outstanding axle collar passes the hole in the base part and is out of shape then so that handle portion and base part are fixed together, and still allows the rotation of handle portion with respect to base part simultaneously.

This manufacturing approach is relatively costly, and the length of axle was confirmed during the initial fabrication stage.

The invention provides the handle that comprises handle portion, base part and axle, handle portion is rotatable with respect to base part, but is maintained at the correct position to base part between ledge through base part being clipped in axle and the handle portion.

The ledge of axle can comprise the packing ring of threaded shaft.

Packing ring can through with axle on shoulder engage the correct position that remains on the axle.

The inner of axle is preferably held tight in one's hands in handle portion.

Preferably, the inner of axle is interference fitted in the socket of handle portion.

The inner of shaft portion can have protuberance, to increase holding tight in one's hands between axle and the handle portion.

Protuberance can comprise a plurality of annular barb.

The inside of axle can be taper.

The angle of taper can be 0.5 ° to 0.75 °.

About the opinion of other embodiment, the inner of shaft portion and the interior section of handle portion have the plane of matching, to reduce the risk of handle portion with respect to the shaft portion rotation.

Handle portion is preferably processed by plastic material and axle preferably is made of metal.

The preferred material that is used for handle portion is ABS.

This ABS can be electroplated.

The preferred material that is used for axle is a mild steel.

Base part can be provided with covering cap, for example to hide one or more fixing holes.

Covering cap also can be process by ABS and can be electroplated.

In selectable embodiment, handle is aluminium or magnesium die casting.

To with reference to accompanying drawing the specific embodiment of the present invention be described through the method for embodiment now, in the accompanying drawings:

Fig. 1 is the decomposition diagram of the embodiment of handle according to the present invention;

Fig. 3 is the elevation of handle;

Fig. 4 is a handle sectional view of taking from the line A-A of Fig. 3;

Fig. 4 a and Fig. 4 b are the more detailed views of part of the sectional view of Fig. 4;

Fig. 5 is the view similar with Fig. 3, shows handle second embodiment of the invention;

Fig. 6 is the sectional view on the line B-B of Fig. 5; And

Fig. 7 is the phantom drawing on the axle of the embodiment shown in Fig. 5 and Fig. 6.

Is handle portion 10, base part 11 and axle 12 at Fig. 1 to the critical piece of the handle shown in Fig. 4 b.In use; Handle portion 10 must be rotatably installed on the base part 11; While axle 12 passes base part 11 and from handle portion 10, gives prominence to; And enter into window or door, and so that handle portion 10 causes the rotation of axle 12 in window or door with respect to the rotation of base part 11, thus the mechanism of actuating doors.

This embodiment of the present invention relates generally to the method that

parts

10,11 and 12 are assembled and tighten together.

In any case handle necessarily comprises locking assembly 13, locking core pipe (locking barrel) 14 and covering cap 15.

When handle in use, locking core pipe 14 can be operated so that handle portion 10 is locked in the correct position with respect to base part 11, thus locking window or door.

Parts

10,11,13 and 15 can be molded as by plastic material.Axle 12 is made of metal with locking core pipe 14.

Handle portion 10 has outstanding circular cross section lug boss (boss) 16, and the hole that lug boss 16 in use passes in locking assembly 13 and the base part 11 is outstanding.The orientation direction handle portion of lug boss 16 in the hole of base part 11 is to rotate with respect to base part 11.

Metal shaft 12 is become by one section square cross section made; Its quilt turning downwards is to provide cylindrical part 17; And the end of cylindrical part further processes so that annular barb rib 18 to be provided then, and the profile of barb rib 18 illustrates in greater detail in Fig. 1 a.

The downward turning of part 17 provides square cross section shoulder 19.

Such as in Fig. 4 b the best see that the hole 20 in the base part 11 also has shoulder 21.

Handle is provided with packing ring 22, and packing ring 22 has the interior diameter bigger a little than the part 17 of axle 12, makes packing ring can slip over the

part

18 and 17 of axle 12, reaches up to packing ring to lean on square cross section shoulder 19.

Packing ring 22 has external diameter, to such an extent as to this external diameter can not directly pass the hole 20 in the base part 11 too greatly for packing ring, but can be engaged in the hole that provides by shoulder 21 than in the major diameter part, such as in Fig. 4 b the best see.

Through making axle 12 pass the hole in packing ring 22, base part 20, the locking sub-component 13 and enter into lug boss 16, critical component is fixed together very simply.Such as in Fig. 4 a the best see that part 18 is dimensioned to and is interference fitted in the lug boss 16.

In order to help that part 18 is pushed the socket in the lug boss 16, part 18 can be provided with the angle of slight taper, for example from 0.5 ° to 0.75 °.

In other words, the part 18 of axle 12 is pushed in the lug boss 16 and can not recalls from here subsequently.Part 18 is held tight in one's hands securely in lug boss 16, and is by holding tight in one's hands of providing of this interference fit parts to be kept together, and still allows handle portion 10 with respect to base part 11 rotations simultaneously, only if its operational lock through locking core pipe 14 is at correct position.

Locking core pipe 14 and locking sub-component 13 are assemblied in mode in the handle 10 shown in the sectional view of Fig. 4, but will not be described in detail, because these parts are common.

Have in the base part 11 and be used for base part is installed in the hole 23 on window or the door.In use, in the fixing hole 23 one by handle 10 like Fig. 3 and shown in Figure 4 hiding, and in order to make assembly have aesthetic feeling, another hole 23 is capped through being clipped on the covering cap 15.

Handle portion 10 can be processed by any appropriate plastic material with base part 11, preferred PC or ABS.ABS has the advantage that can be electroplated.

Base part 11 can be processed by analog material, perhaps can be the zinc die casting.

Axle 12 is preferably processed by mild steel.

Covering cap 15 also can be processed by PC or ABS.

Locking assembly 13 can be processed by ABS or nylon.

Locking core pipe 14 can be by any suitable metal.

In the embodiment shown in Fig. 7, axle 12 is provided with plane 24 (see figure 7)s and handle 10 is provided with respective planes 25 (see figure 6)s at Fig. 5.Match to guarantee that axle can not slide and rotate in handle in these planes.

In another embodiment, handle can comprise aluminium die casting or magnesium die casting.

All main manufacturing steps were accomplished before the final assembling of parts, and the final assembling of parts can be carried out at the scene, perhaps carried out at the later stage of making.Thereby the length of axle 12 can be selected to be fit to on-site parameters at the eleventh hour, for example the thickness of window or door.
