Description

SCREWLESSLY MOUNTABLE DOOR HANDLE

The invention relates to a door handle for mounting screwlessly to a door handle shaft, wherein the door handle has a mounting part and a handle part which are connected with each other so that an axial force on said handle part is transmitted to said mounting part, which handle contains fixing means to be mounted to said door handle shaft.

Such a door handle is known from US 4607973. This document describes how a door handle and a door handle shaft are fitted with a pinhole connection wherein one of the said door handle or door handle shaft contains the pin and the other of said door handle or door handle shaft contains the hole. The pin can be extended in its axial direction and fitted with a spring such that the pin is forced outward. On mounting such a door handle on a door handle shaft, first the pin is pushed in against the spring force, then the door handle is pushed over the door handle shaft to reach a point where the pin and the hole are aligned so that the spring pushes the pin into the hole. The advantage of such a connection is that no tool, in particular a screwdriver, is required to attach the door handle to the door handle shaft.

One disadvantage of the known door handle is that both the door handle and the door handle shaft must be adapted to be complementary to each other. As a result a conventional door handle shaft cannot be used. A further disadvantage of the known door handle is that a connection is possible only in one predetermined position of the handle with respect to the handle shaft, namely the position in which the pin and the hole are aligned. As a result on assembly it cannot be selected how deep the door handle shaft is attached in the door handle, whereby the resulting play in the axial direction must be absorbed by other complex systems. One aim of the present invention is to provide a door handle which allows a more flexible fixing on a door handle shaft.

For this the door handle according to the invention has the feature that said fixing means are formed by clamping means which are actively connected with said handle part to cause clamping as a result of a movement of said handle part with respect to said mounting part in a direction perpendicular to the door handle shaft direction. In contrast to a pin-hole connection, a clamp connection does not require each of the two elements to be combined to be complementary connection means. Also a clamp connection allows a connection to be achieved in different mutual positions which is not the case with a pin-hole connection where a connection can only be achieved if the pin and hole are aligned.

Because clamping can be caused as a result of movement of a handle part with respect to the mounting part, no tool such as a screwdriver is required. The handle part can be held in one hand and the mounting part in the other hand to achieve the movement. If the mounting part is pushed over the door handle shaft which sits in a door lock, only the handle part need be held on mounting as the door handle shaft does not allow any movement perpendicular to the shaft direction. As a result such an installation cannot merely be performed by experienced handymen.

Preferably said mounting part has a housing within which said clamping means are held, which clamping means are mobile with respect to said housing in the door handle shaft direction, and are designed to cause said clamping by displacement in the direction of said handle part.

On mounting of such a door handle, the housing of the mounting part can be pushed over the door handle shaft to largely against the door and/or handle plate. On clamping of the clamping means, this displacement within the housing takes place in the direction of the handle part i.e. in a direction away from the door. The clamping means will fasten in the clamping movement on the door handle shaft, whereafter the clamping means can no longer be moved with respect to the shaft while the housing stands still with respect to the door handle shaft, but the housing will move with respect to the door handle shaft. As a result the door handle on mounting will be pulled towards the door, reducing play in the axial direction.

Preferably said handle part comprises a wedge-shaped sliding element which provided to cause a displacement of said clamping means with respect to said housing in a first door handle shaft direction due to said movement. A wedge is a very simple technical means for driving two elements apart in a first direction by exercising a force on the wedge in a second direction perpendicular to this first direction. A wedge also allows in a technically simple manner a movement in the axial direction of the housing and clamping means with respect to each other by movement of said handle part and mounting part with respect to each other perpendicular to the axial direction.

The invention furthermore relates to a set for mounting a door handle on a door with a door handle opening, the set comprising at least one door handle according to one of the preceding claims and a door handle shaft. The advantage of such a set is that in contrast to conventional door handles, the door handle shaft is not preassembled with one of the two door handles. As a result compact packing is possible. This has consequences not only for transport costs but also the compact packaging ensures less damage to the door handle during transport.

The invention will now be described with reference to an embodiment example shown in the drawing.

The drawing shows: Fig. 1 a door with door handle opening; Fig. 2 a fitted clamping element; Fig. 3 an inserted anchoring element; Fig. 4 a cross section of a handle plate in mounted state; Figs. 5a and 5b a door handle in a first loose position; and Figs. 6a and 6b a door handle in a second fixed position.

In the drawings same or similar elements have the same reference numerals.

Fig, 1 show a door 1 which is designed so that the operating mechanism can be mounted. For this the door 1 has an opening 2 which, as shown in further figures, allows attachment to the door 1 of a door handle 16 and a handle plate 12. The door 1 furthermore has a slot 3 provided in the side, where for example an integral lock can be mounted. The opening 2 is preferably located at the level of the slot 3 and preferably gives access to this slot 3 so that cooperation of the door handle 16 and the integral lock is possible. However a handle plate 12 according to the invention can also be mounted on an opening 2 in a door 1 without this opening 2 being connected with the slot 3. The invention is therefore not limited to handle plates on door handles that are connected with a lock. A handle plate 12 according to the invention can also be mounted on door knobs and door handles which are not connected with a lock mechanism.

For reasons of clarity it must be pointed out that the term 'handle plate 12' is used to indicate all means which are designed, for both functional and aesthetic reasons, to be mounted between the door handle 16 or door knob and the door 1 itself. These include the handle surround, the plate, the decor panel and rosette, all of which are referred to as handle plate 12. The term 'handle plate 12' also includes a rosette or decor panel which is mounted on the key opening (not shown), or mounted on the combination of handle shaft opening 2 and key opening, since these can also be designed and fitted according to the invention. This term 'handle plate' should therefore according to the invention not merely be interpreted as a handle plate as such.

A set for mounting a handle plate 12 according to the invention contains a number of elements which will be further explained with reference to figures 2 to 4. Figure 2 shows a clamping element 4 which has a largely cylindrical clamping part 6 and a clamping element collar 5, whereby the clamping part 6 can expand radially. The clamping part 6 has an outer diameter which is largely equal to the diameter of the door handle opening 2. Preferably the outer diameter of the clamping part 6 in a radially unexpanded state is at least 0.1 mm smaller than the diameter of the door handle opening 2, so that it is possible to locate this without substantial force. Preferably the outer diameter of the clamping part 6 in a radially unexpanded state is maximum 2 mm smaller than the diameter of the door handle opening 2, so that clamping by radial expansion remains possible. Preferably the cylindrical clamping part 6 has a length measured in the axial direction of at least 2 mm, more preferably at least 4 mm and most preferably at least 5 mm.

Preferably the collar 5 of the clamping element 4 is fitted with screwdriver passage openings 7. These screwdriver passage openings 7 should preferably not be used on mounting according to the invention. However if clamping in the door handle opening 2 due to radial expansion of the clamping part 6 is difficult, for example because the door handle opening 2 is damaged, the clamping element 4 can still be fastened by screws to allow further mounting of the handle plate 12.

The largely cylindrical clamping part 6 according to the invention is radially expandable, which can be achieved by various technical means. For example the cylindrical part 6 can be made of a material which has a certain flexibility, whereby the outer diameter can expand by stretching the material. Figure 2 shows a clamping part 6 which comprises radially mobile elements designed as hinge means 8. These hinge means 8 are incorporated in the wall of the cylindrical clamping part 6 and form part of this wall. The hinge means 8 have a thickness measured in the radial direction which is greater than the wall thickness of the cylindrical part. Here it must be pointed out that the hinge means 8 need not necessarily have a constant thickness. The hinge means 8 as shown in figure 2 are wedge-shaped and do not have a constant thickness over their complete surface measured in the radial direction. The hinge means 8 increase in thickness in the direction away from the collar 5 over the cylindrical part. The hinge means 8 are connected with the cylindrical wall at the level of the collar 5, i.e. where the hinge means 8 have the minimum thickness.

Because the hinge means 8 have a thickness which is greater than the wall thickness of the cylindrical part and are radially mobile by being connected pivoting with this wall, the hinge means 8 can be positioned so that, considering only the outer surface of the cylindrical part, they are sunk into the cylindrical part. In such a position which is considered the extreme innermost position, the hinge means 8 protrude partly to the inside of the cylindrical part, whereby the inner diameter of the cylindrical part is determined by the hinge means 8 and is smaller than the inner diameter of the cylindrical clamping part 6. The hinge means 8 can also be positioned in the extreme outermost position in which the hinge means 8, considering the inner surface of the cylindrical part, are sunk into the inner surface. However in such an extreme outermost position, the hinge means 8 would protrude radially to the outside of the cylindrical part so that the outside diameter is no longer determined merely by the cylindrical part but at least partly also by the hinge means 8. As a result said clamping part 6 can be regarded as radially expandable by adaptation of the hinge means 8 in the cylindrical surface. The hinge means 8 with a thickness which is greater than the wall thickness should be interpreted according to the invention as at least part of the hinge means 8 which must be thicker than the cylindrical wall thickness. Namely the hinge means 8 as explained above must make the clamping part 6 radially expandable if only part of the hinge means has a thickness measured in the radial direction which is greater than the wall thickness of the cylindrical clamping part 6.

It will be clear that variations on the embodiment described above are possible. Thus a different number of such elements can be incorporated or attached to the clamping element 4 to make the latter radially expandable. Therefore the invention is not limited to the hinge means 8 as presented in the figures and as described above.

Figure 3 shows a clamping element 9 according to the invention. This anchoring element 9, like the clamping element 4, has an anchoring element collar 10 and a largely cylindrical anchoring part 11. The anchoring part 11 has an outer diameter which fits tightly in the inner diameter of the clamping part 6. It must be noted that the inner diameter of the clamping part 6 must be understood as the inner diameter of the cylindrical wall part of the clamping part 6, and that to determine the inner diameter of the clamping part 6, the radially mobile elements are disregarded. The anchoring part 11 has an outer diameter which is largely equal to the inner diameter of the clamping part 6. Preferably the outer diameter of the anchoring part 11 is at least 0.1 mm smaller than the inner diameter of the clamping part 6 so that a tight fit occurs without excessive force being required. Preferably the outer diameter of the anchoring part 11 is maximum 2 mm smaller than the inner diameter of the clamping part 6. Preferably the cylindrical anchoring part 11 has a length measured in the axial direction of the cylinder of at least 2 mm, more preferably at least 4 mm, most preferably at least 5 mm. Preferably the length of this cylindrical anchoring part 11 is selected such that when the anchoring part 11 is driven fully into the clamping part 6, the cylindrical anchoring part 11 extends at least completely over the cylindrical clamping part 6.

The collar 10 of the anchoring element 9 is provided on installation to define a definitive final position of the anchoring element 9 with respect to the door 1. Furthermore the collar 10 can comprise handling facilities such as a hexagonal periphery to be operated by a key.

Not every door 1 has a door handle opening 2 of the same diameter. As the outer diameter of the clamping element 4 must be approximately equal to the diameter of the door handle opening 2, at least one of the two diameters must be adapted to achieve this. The invention provides a filler ring 15 to fit between the door handle opening 2 and the clamping part 6 as shown in figure 4a, where the filler ring 15 artificially reduces the diameter of the door handle opening 2. Figure 4b shows a mounted set according to the invention wherein the diameter of the door handle opening 2 is such that no filler ring 15 is necessary. The advantage of working with a filler ring 15 is that the clamping part 6 and anchoring part 11 need only be provided in a single size and yet can still be mounted on different door handle openings 2. This is beneficial with regard to production costs. However also the fact that several filler rings 15 of different dimensions can be supplied with a set for mounting a door handle plate 12 according to the invention means that one single set can be mounted on various types of door handle opening 2. This is not only a benefit with regard to transport and logistics, namely a customer need no longer know the diameter of the door handle opening 2 before being able to buy a set for mounting a handle plate 12, since because the set has several filler rings 15, it can be mounted on different door handle openings 2. A filler ring 15 according to the invention should preferably be made of a deformable material so that the radial expansion of the clamping element 4 achieves both clamping of this clamping element 4 in the filler ring 15 and clamping of the filler ring 15 in the door handle opening 2. For this the filler ring 15 must be able to transmit at least part of the radial expansion and thus itself expand radially.

A handle plate 12 according to the invention comprises fixing means for fixing the handle plate 12 to the clamping element 5 and/or anchoring element 9. Preferably the handle plate 12 has an edge which can be clipped over a lip 13 of the anchoring element 9. In another embodiment the handle plate 12 has spring means 14 (figure 5) to move the door handle shaft 17 into a predetermined position. These spring means 14 exert a rotational force on the door handle shaft 17. To be able to absorb this rotational force, the handle plate 12 according to the invention can be oblong and connected with the clamping element 4 and/or anchoring element 9 as described above and with an underplate which is mounted on the key opening.

The method for mounting the handle plate 12 according to the invention is as follows. Optionally the door handle opening 2 is artificially reduced by the fitting of a filler ring 15. This filler ring 15, instead of being placed in the door handle opening 2, can also be pushed over the clamping part 6 not yet fitted. The clamping part 6 of the clamping element 4 is then placed in the door handle opening 2 so that the collar 5 of the clamping element 4 lies against the door 1. Optionally the clamping element 4 can be screwed to the door using the screwdriver openings 7. Screwing on a clamping element 4 is simple as the clamping element 4, because the clamping part 6 is placed in the opening 2, largely remains in place and need not be held in a predetermined position during screwing or drilling of screw holes in the door 1. The anchoring element 9 is provided to be mounted after the clamping element 4 has been placed in the door handle opening 2. The anchoring part 11 is provided to be driven into the clamping part 6 of the clamping element 4. The anchoring element 9 as shown in figure 3 is driven into a clamping element 4 as given in figure 2 by pushed under force or pressing the anchoring part 11 into the clamping part 6 which is placed in the door handle opening 2. However the invention is not limited to driving the anchoring part 11 into the clamping part 6 by pushing. Driving by screwing, whereby an inside of a clamping part 6 and an outside of the anchoring part 11 are fitted with complementary screw threads, can achieve the same effect as provided by the invention and therefore falls under the term 'driving¹.

The effect of driving the cylindrical anchoring part 11 into the clamping part 6 is that as a result the clamping part 6 expands radially. The radial expansion causes the clamping part 6 to fasten in the door handle opening 2, whereby a connection is achieved based on friction resistance between clamping part 6 and/or handle opening 2. The driving of the anchoring^part_JJ__into_the_clampJng__part jS_rejq.uires__a__certajαJQrce,_ namely the anchoring element 9 when driven in will exert a radial pressure on the clamping part 6. The driving force is thus at least partly converted into a radial expansion force of the clamping part 6. Because the anchoring element 9 exerts a radial pressure on the clamping part 6, a friction resistance also occurs between the anchoring part 11 and the clamping part 6. As a result the anchoring part 11 , after the clamping part 6 has been driven in, can be considered connected with the clamping part 6 and the door handle opening 2.

According to one specific embodiment as shown in the figures, driving the anchoring part 11 into the clamping part 6 with the hinge means 8 has the following effect. The clamping element 4 is placed in the door handle opening 2 as shown in figure 2, wherein the hinge means 8 are in the innermost position. The inner diameter of this clamping element 4 is therefore, at the level of the hinge means 8, smaller than the inside wall diameter of the clamping part 6. When the anchoring part 11 is driven into the clamping part 6, the anchoring part 11 with its fixed outer diameter presses the hinge means 8 outwards. Because the hinge means 8 are wedge-shaped and because the point part of the wedge is facing towards the collar 5, this outward pressure will be progressive in parallel with the progress of driving the anchoring part 11 into the clamping part 6. One advantage of wedge-shaped radially mobile elements is that the clamping force is built up as the anchoring element 9 is driven deeper into the clamping element 4, which facilitates installation.

The pressure with which the anchoring part 11 must be driven into the clamping part 6 depends on various factors. The tolerances of diameters with respect to each other e.g. the outer diameter of the anchoring part

11 to the inner diameter of the clamping part 6, are a decisive factor. Also the hardness of the material from which in particular the radially mobile elements are made is also decisive. Furthermore the thickness of the radially mobile elements with respect to the difference between the outer diameter of the anchoring part 11 and the diameter of the door handle opening 2 is also decisive.

As the clamping element 4 and anchoring element 9 are connected with the door, a handle plate 12 can be attached to the clamping element 4 and/or anchoring element 9. Preferably the handle plate 12 is clipped onto the clamping element 4 and/or anchoring element 9. In the embodiment as shown in figure 4, for this the collar 10 of the anchoring element 9 has a lip 13 onto which the handle plate 12 can be clipped. However the invention is not limited to clipped embodiments. According to the invention the anchoring element 9 and/or clamping element 4 can also be fitted with a screw thread so that a handle plate 12 with complementary screw thread can be screwed onto this. Figure 5 and figure 6 each show a side view (figure 5a and figure 6a) and a top view (figure 5b and figure 6b) of a door handle 16 which can be mounted screwlessly onto a door handle shaft 17. Figure 5 shows the door handle 16 placed on a shaft in a state not yet fixed. Figure 6 shows the door handle 16 placed on a shaft in a fixed state.

Figures 5 and 6 show a door handle shaft 17 which extends horizontally such as a door handle shaft 17 when it is in the door lock in a rest state. The figures furthermore show a handle plate 12 against which the door handle 16 is mounted. The door handle shaft 17 shown in the figures has a square cross section whereby two opposing sides have teeth which function as counter hooks, while the other two opposing sides are flat. It will however be clear that door handle shafts with different cross sections and in different embodiments, with and without counter hooks, can be used in the invention.

Figure 6 shows a handle plate 12 which has spring means 14 to turn the door handle shaft 17 into a predetermined position. Figure 6 shows a conventional handle plate 12 without spring means 14.

Figures 5 and 6 show a door handle 16 comprising a mounting part 18 and a handle part 19. The handle part 19 is shown in the figures as a lever which extends in one horizontal direction. However the invention is not limited to such a lever. According to the invention the specific form of the handle part 19 is irrelevant as long as it can be gripped.

The mounting part 18 and handle part 19 are connected to each other so that a rotation force exerted on the handle part 19, as occurs on opening of a door, is transferred to the mounting part 18 which in turn is connected with the door handle shaft 17 such that this door handle shaft 17 can be rotated. The door handle shaft 17 is preferably connected with a lock mechanism so that on operation of the door handle 16, the door 1 can be opened.

The mounting part 18 and handle part 19 are mobile with respect to each other. Two positions are given, one in each of figures 5 and 6. In particular a movement of the handle part 19 with respect to the mounting part 18 in a direction largely perpendicular to the handle shaft direction is possible. Largely perpendicular means a movement with a direction which has at least one component in the perpendicular direction. Preferably a movement of the handle part 19 with respect to the mounting part 18 is possible in a direction which forms an angle of between 60° and 120° with the door handle shaft direction, more preferably between 80° and 100°, and most preferably between 85° and 95°.

The mounting part 18 comprises fixing means 20 to connect the door handle 16 with the door handle shaft 17. These fixing means are shown in figures 5 and 6 as clamping means 20. These clamping means 20 are formed by a U-shaped body and comprise two legs 21 , between which the door handle shaft 17 is clamped on mounting so that the door handle shaft 17 is connected with the clamping means 20. The clamping means 20 are placed in a housing 22 and clamping means 20 and housing 22 together form the mounting part 18.

The clamping means 20 can move with respect to the housing 22 in the handle shaft direction. The housing 22 has two sliding surfaces 23 which are provided to guide the two legs 21. Each of the two legs 21 contains at its end a thickening in the direction of the housing 22 to cooperate with the sliding surfaces 23 on the housing 22. The sliding surfaces 23 and thickenings are arranged so that on displacement of the clamping means 20 in the direction of said handle part 19, the legs 21 are moved towards each other whereby the legs 21 will clamp on the door handle shaft 17.

For this the sliding surfaces 23 are placed at an angle with respect to the door handle shaft direction. Preferably this angle is between 2° and 30°, more preferably between 5° and 15°. To make the connection by clamping more effective, the legs 21 on the inner edges can be fitted with one or more teeth which act as counter hooks on the door handle shaft 17.

It will be clear that variations on the embodiment shown are possible. Thus clamping means 20 can also be formed by just one leg or by three or more legs 21. Also sliding surfaces 23 can be oriented so that a clamping is caused on movement of the clamping means 20 with respect to the housing 22 in a direction away from the handle part 19.

The handle part 19, the housing 22 and the clamping means 20 are functionally connected to allow a movement of the clamping means 20 with respect to the housing 22. In the embodiment shown in figures 5 and 6, the clamping means 20 are connected with the handle part 19 by a dovetail connection. Here a dovetail connection means a connection wherein movement is permitted in one direction, the movement direction, while all other movements such as forwards, sideways and rotating movements are prevented. Here the term 'dovetail connection¹ also includes connections which deviate from the typical dovetail form as shown in figures 5 and 6. Because movement in one direction is still permitted, a dynamic connection is obtained, the function of which will be explained below.

The handle part 19 contains a groove 24, the dovetail groove, in which a complementary engagement element 25, the dovetail, of the clamping means 20 engages. The engagement element 25 and the groove 24 form the dovetail connection. The groove 24 is placed at an angle (α) to the surface perpendicular to the handle shaft direction. Preferably the groove 24 is placed at an angle between 85° and 50° to the handle shaft direction, more preferably between 80° and 75°. Furthermore the handle part 19 comprises a sliding surface 26 for guiding the housing 22. This sliding surface 26 is preferably perpendicular to the handle shaft direction whereby an angle (α) occurs between groove 24 and sliding surface 26. The effect of this angle (α) is that on movement of the handle part 19 with respect to the mounting part 18, a movement is caused of the clamping means 20 which follow groove 24 with respect to housing 22 which follows the sliding surface 26. In this way a movement with at least one component in a direction perpendicular to the door handle shaft direction can be converted into a movement in the door handle shaft direction.

In other words it can be said that the handle part 19 comprises a wedge- shaped guide element with a first and a second sliding surface 26 and 27 respectively. The first sliding surface 26 is provided to guide the housing 22 in a direction perpendicular to the door handle shaft direction. The first and second sliding surfaces 26 and 27 stand at an angle (α), whereby the continued movement of the wedge-shaped element causes a displacement of clamping means 20 with respect to the housing 22 in the direction of the handle part 19. Furthermore the handle part 19 has a return sliding surface 28 such that on movement of the handle part 19 in the release direction, wherein the wedge-shaped element is withdrawn, the clamping means 20 are moved in a direction away from the handle part 19.

Preferably the movement of the handle part 19 with respect to the mounting part 18 cause the clamping has a largely downward vertical direction. The effect is that conventional opening of a door 1 has no dismantling effect on the door handle. Namely to open a door 1 , the handle should be pressed down. Mounting of such a door handle 16 on a door handle shaft 17 is also very simple, namely on installation the door handle shaft 17 mostly sits in a door lock in such a way that this door handle shaft 17 can only be moved in the axial direction. As a result a force on the door handle shaft 17 in a direction perpendicular to the axial direction can be absorbed. The mounting part 18 is pushed over the door handle shaft 17 such that only a movement of the mounting part 18 with respect to the door handle shaft 17 in the axial direction is possible. In such a position, on exertion of an external vertical force on the handle part 19, counter force is supplied because the mounting part 18 and the door handle shaft 17 are not mobile in this vertical direction. The door handle 16 can thus be attached to the door handle shaft 17 by one single downward force.

Preferably the handle part 19 has a locking lip (not shown) such that after mounting the handle part 19 is prevented from movement with respect to the mounting part 18 such that no undesirable dismantling of the door handle can take place. This locking lip can be formed so that a tool specially adapted to this is required to remove the door handle. This offers a benefit with respect to security.

The mounting of a handle plate 12 in combination with mounting of a door handle 16 as described above has the advantage that simple installation is possible without unavoidable consequences such as screw holes, and that furthermore no essential tools are required. A secondary advantage is that the door handle 16 can be mounted and dismounted completely separately from the handle plate 12. As mounting of the handle plate 12 often occurs when a door 1 is painted and when the paint has not completely dried, dismantling of such a door handle 12 causes the paint to detach. It is therefore beneficial to be able to remove the door handle 16 while the handle plate 12 remains mounted, namely otherwise the paint detaches.
