The invention relates to a handle for operating a window or door.
The handle neck comprises an upper handle neck portion and a lower handle neck portion, where the upper handle neck portion extends in a first longitudinal direction, and the second handle neck portion extends in a second longitudinal direction. The first longitudinal direction defines a first angle in relation to the surface main plane, and the second longitudinal direction defines a second angle in relation to the surface main plane, where the second angle being numerically larger than the first angle. Hereby, the handle grip can be arranged at an increased distance from a window sash compared to the distance from the longitudinal direction of an operating spindle towards the sash.
The present invention relates to a handle for operating a window or a door.
For the sake of simplicity, in the following description, the invention will only be described in relation to windows. However, the invention might as well be implemented in relation to doors, stutters etc. and should therefore also be interpreted in relation thereto.
Compared to traditional windows with a traditional sash construction, e.g. made of a wooden profile, windows having a slim profile construction enhances the incident light, enhances the view out the window and enhances the visual properties of the building in which the window is mounted.
Within the recent years, as the demand for incident light, enhanced view and for enhanced visual properties of the building constructions increases, the properties of the sash construction of the windows tend to get slimmer, which challenges the other part of the window, such as the frame construction, the hinges and the window handles.
As the window sash profiles gets slimmer, a problem arises with implementing known types of operating handles, especially pivoting operating handles, which pivot around an axis perpendicular to the plane of the window. The small width of the window sash results in the handle being in close proximity of the window frame, leaving very little or even no room for a user's hand to grasp the operating handle without interfering with the window frame, which could leave to injury and eventually wear on the window frame from the user's hands and/or the operating handle. Further, when implementing operating handles having a key lock (or any other type of lock associated with operating handles) a user may have difficulty operating the key/lock without interfering with the window frame. This may lead to the window not being properly locked or an incorrect operation of the key leading to malfunctioning or destruction of the key and/or lock.
The object of the present invention is to advise an operating handle which eliminates the above mentioned drawbacks by being manufactured in a way allowing the handle to be installed in a window having a slim profiled sash and allowing a user to operate the handle without interfering with the window frame. The object of the invention is to advise a handle where the distance from the handle grip to a sash part of a window is increased compared to known types of operating handles.
The above object and advantages together with numerous other objects and advantages, which will be evident from the description of the present invention, are according to an aspect of the present invention obtained by:
- A handle for operating a window or door and for operating a latching mechanism of the window/door and for being rotated about an axis of rotation, from a first position in which the latching mechanism of the window/door is locked, to a second position in which the latching mechanism of the window/door is unlocked and where the axis of rotation is approximately perpendicular to a surface main plane of the window/door, the handle having:
  - a handle neck for being connected to an operating spindle for manipulating the latching mechanism of the window/door and having a longitudinal direction being approximately perpendicular to the surface main plane of the window/door,
  - a grip connected to the handle neck for allowing a user to operate the handle,
- the handle neck having an upper handle neck portion extending in a first longitudinal direction of the handle neck, the first longitudinal direction defining a first angle in relation to the surface main plane, and a lower handle neck portion extending in a second longitudinal direction of the handle neck, the second longitudinal direction defining a second angle in relation to the surface main plane, the second angle being numerically larger than the first angle.
A handle neck having two handle neck portions being individually angled in relation to the surface main plain of the window has the unique effect that the handle grip can be arranged at an increased distance from a window sash compared to the distance from the longitudinal direction of the operating spindle towards the sash.
Preferably, the first angle is numerically in the range between 40-80 degrees, more preferably in the range between 50-70 degrees, most preferably 60 degrees.
The second angle is preferably in the numerically range between 60-90 degrees, more preferably in the range between 70-80 degrees, most preferably 75 degrees.
Typically, the components of the handle is manufactured from stainless steel, aluminum, copper, or a combination of two or more materials. However, other materials for the components parts may be nylon, porcelain etc., or any other suitable materials known to the skilled person.
The handle is throughout the description disclosed as a handle mostly suitable to be arranged on a left or bottom side of a window, however, it is obvious that the handle may be manufactured inverted, in order to be arranged at a right side of a window.
According to a further embodiment of the invention, the upper handle neck portion comprises a locking mechanism, the lower handle neck portion comprises a handle neck seat having a through-going opening extending in a direction towards the surface main plane, the handle neck seat further comprises a spindle seat, preferably a quadrangular spindle seat, for accommodating an operating spindle arranged in a direction substantially perpendicular to the surface main plane. The through-going opening is accommodating a locking pin for being activated by the locking mechanism between a position, where the locking pin is projecting from the lower handle neck portion for engaging a handle escutcheon, and a retracted position where the locking pin is in a non-projecting position for being in a non-engaging position with the escutcheon.
The handle neck seat may be manufactured as a separate element being fixedly arranged within the lower handle neck portion. The handle neck seat may be manufactured, e.g. by molding, as an integrated part of the handle neck.
Further, the locking pin may have an enlarged head being accommodated in the through-going opening between the handle neck seat and the locking mechanism. The enlarged head abuts against the lower end of the locking mechanism, and acts as a shoulder for a biasing lock pin spring, coiled around the locking pin, which spring urges the locking pin in a direction towards the locking mechanism.
According to a further embodiment of the invention, the locking mechanism is a cylinder lock.
Preferably, the cylinder lock is a pin tumbler lock, such as a 6-pin cylinder lock. However, the invention should not be limited to a 6-pin cylinder lock. A different type of lock or cylinder lock having a different pin number may be used.
According to a further embodiment of the invention, the locking mechanism is engagingly displaceably arranged between two end positions within a handle neck bore of the upper handle neck portion.
The cylinder lock is displaceable between a first position, in which the cylinder lock in the first longitudinal direction is substantially fully arranged within the upper handle neck portion, and a second position, where the cylinder lock is displaced in the first longitudinal direction, to a position partly outside the upper handle neck portion. The longitudinal displacement of the cylinder lock is substantially equal to the longitudinal displacement of the locking pin. Hereby, the movement of the cylinder lock effects the movement of the locking ping which hereby engages/disengages the escutcheon.
According to a further embodiment of the invention, a cylinder lock spring is arranged inside the handle neck between the locking mechanism and the handle neck seat for effecting a pressure force on the locking mechanism in the first longitudinal direction, and away from the handle neck seat.
The cylinder lock spring is preferably a coil spring, urging a pressure force against the cylinder lock in the first longitudinal direction. Alternatively, different types of spring elements may be used, such as a leaf spring or torsion spring.
According to a further embodiment of the invention, the handle neck seat has a lower surface for facing the escutcheon and for being arranged substantially parallel to the surface main plane, where the spindle seat is arranged at the lower surface of the handle neck seat, where the handle neck seat is further having an upper surface, opposite the lower surface for facing the upper handle neck, the upper surface defining a plane being perpendicular to the second longitudinal direction.
According to a further embodiment of the invention, the through-going opening of the handle neck seat is extending from the upper surface to the lover surface.
The through-going opening preferably has a first part with a diameter which is substantially equal to the outer diameter of the shaft of the locking pin. The through-going opening has a second part having an enlarged diameter which is substantially equal to the outer diameter of the enlarged heat of the locking pin and to the outer diameter of the biasing lock pin spring coiled around the shaft of the lock pin.
According to a further embodiment of the invention, the locking mechanism comprises at least one locking pawl being displaceably arranged within a first pawl bore of the locking mechanism, by activation of the locking mechanism, for selectively being in a first position where the locking pawl projects from the locking mechanism into a recess arranged at an inner surface of the handle neck bore, and in a second position where the locking pawl is in a retracted position in relation to the recess.
The locking pawl enables the locking mechanism to be selectively engaged or disengaged in relation to the upper handle neck portion within the two end positions. The locking mechanism is typically operated by a user with a key being rotationally engaged with the locking mechanism, whereby rotation of the key activates the locking mechanism which retracts the locking pawl from engagement with the recess.
According to a further embodiment of the invention, the locking mechanism comprises a release pawl, for releasing the locking mechanism from the engagement with the handle neck bore, the release pawl being spring activated and displaceable between a first position where the release pawl projects from the locking mechanism into a longitudinal groove arranged at an inner surface of the handle neck bore, the longitudinal direction being arranged in a direction parallel to the first longitudinal direction.
The release pawl may be disengaged from the longitudinal groove e.g. by pressing the pawl with a suitable tool such a thin needle via a small opening in the upper handle neck portion. Hereafter, the cylinder lock may be removed out of the upper handle neck portion.
According to a further embodiment of the invention, the handle neck seat is fixedly arranged within the lower handle neck portion.
The handle neck seat may be permanently mounted within the lower handle neck portion or integrated by e.g. moulding, or may be removable arranged within the lower handle neck portion.
According to a further embodiment of the invention, the handle further comprises an escutcheon for being mounted to a sash.

The present invention wilt now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout. Like elements will, thus, not be described in detail with respect to the description of each figure.
Figs. 1A-1C show a perspective view of a handle 10 for a window (not shown) in a locked position. The handle 10 comprises a handle neck having an upper handle neck portion 14 and a lower handle neck portion 16. A grip 12 is arranged at the upper handle neck portion 14, allowing a user to rotate the handle 10 for the activation of a latching mechanism of the window.
The handle 10 may be rotatably seated against a window sash (not shown) via an escutcheon 28, acting as a bearing plate, where the escutcheon can be fixedly mounted to the window sash with suitable fastening means such at screws, bolts or the like, via screw holes 30. A cylinder lock 20 is arranged inside a hollow of the upper handle neck portion 14 for being activated by the insertion and rotation of a key 44.
Figs. 1B-1C show a perspective view of the handle 10 being unlocked, and in fig. 1C rotated counter clockwise into an open position, where a spindle (not shown) extends perpendicular to the surface main plain 60 and into the window sash for activating a window latch.
Fig. 2 shows a view of an upper end of the handle 10. The handle 10 is in a locked position and illustrated in relation to the surface main plain 60 of a window sash.
The handle 10 is mounted to a window sash (not shown) via an escutcheon 28 arranged on a surface main plain 60. The handle neck is seated in an aperture of the escutcheon 28, for rotational movement of the handle 12 in relation to the window sash.
The handle 10 is illustrated with a grip 12, and the handle neck comprises an upper handle neck portion 14 and a lower handle neck portion 16 arranged in abutment with the escutcheon 28. In a mounted position, in relation to the sash, the upper handle neck portion 14 has an extension in a first longitudinal direction 56, which direction defines an angle α_1 in relation to the surface main plain 60.
The lower handle neck 16 has an extension in a second longitudinal direction 58, which direction defines an angle α_2 in relation to the surface main plain 60.
As illustrated, the angle α_2 between the second longitudinal direction 58 of the lower handle neck portion 16 and the surface main plain 60 is numerically larger than the angle α_1 between the first longitudinal direction 56 of the upper handle neck portion 14 and the surface main plain. The first angle α_1 is, in the illustrated embodiment approximately 60 degrees and the second angle α_2 is approximately 75 degrees. This arrangement leads to an increased distance between the grip 12 and a window frame (not shown), compared to a handle having a straight type handle neck.
Fig. 3 shows an exploded perspective view of the handle 10. The figure shows an escutcheon 28, a handle neck seat 24, a grip 12 being connected to a handle neck comprising the upper handle neck part 14 and a lover handle neck part 16.
The escutcheon 28 is arranged with screw holes 30 for affixing the escutcheon 28 to a window sash and a lock pin hole 32 and a central opening for the accommodation of a handle neck seat 24.
The upper handle neck part 14 is illustrated having a neck bore 18, for accommodating a displaceable cylinder lock 20, for being manipulated by a key 44. In the embodiment shown in Fig. 3, the neck bore 18 extends through both the upper handle neck portion 14 and the lower handle neck portion 16.
The displaceable cylinder lock 20 has an outer contour shape corresponding approximately to the shape of the neck bore 18, hereby accommodating the cylinder lock 20 inside the upper handle neck portion 14 in close abutment. The cylinder lock 20 is suitable for being displaced in a direction corresponding to the first longitudinal direction 56. When inserted, the cylinder lock 20 extends into the upper handle neck potion to an extent, where the lower end of the cylinder lock 20, being the end opposite the end of the cylinder lock having a key hole, is arranged proximate a transition between the upper handle neck portion 14 and the lower handle neck portion 16.
The handle neck seat 24, likewise the cylinder lock, 20, has an outer contour shape, corresponding to the shape of the neck bore 18 of the lower handle neck portion 16. The handle neck seat 24 may be permanently or removably affixed within the neck bore 18 of the lower handle neck portion 16. Alternatively, the handle neck seat 24 may be manufactured integrated with the lower handle neck portion 16. At a lower surface, for facing the escutcheon 28, the handle neck seat comprises a quadrangular seat 38, arranged for accommodation with the central bore of the escutcheon 28. Further, the quadrangular seat 38 is arranged for accommodating a square operating spindle, and the side surface of the handle neck seat is illustrated having longitudinal grooves for engaging corresponding protrusions of a washer located on the opposite side of the escutcheon. A seat bore 26 is arranged within the handle neck seat 24, and is formed as a through-going opening for accommodating a lock pin 34, which is displaceably arranged within the seat bore 26. The lock pin 34 is spring biases by a spring 36, illustrated as a coil-spring, and arranged around the lock pin 34 between the lock pin 34 and the seat bore 26, and is biased in a direction towards the upper handle neck portion 14. When being spring biased, a head of the lock pin 34 abuts against the lower end surface of the cylinder lock 20.
Between the handle neck seat 24 and the cylinder lock 20, a lock cylinder spring 22 is being arranged, for exerting a biasing force against the lock cylinder, for displacing the lock cylinder 20 in the second longitudinal direction 58, away from the handle neck seat. When being activated by the key 44, the cylinder lock 20 is displaced in the second longitudinal direction 58 away from the handle neck seat, and the spring biased lock pin 34 moves out of engagement with the lock pin hole 32.
Figs. 4A and 4B show a partly cross-sectioned perspective upper view and a partly cross-sectioned perspective side view of the handle 10 in a locked position.
With reference to both Figs. 4A and 4B, the lock cylinder 20 comprises a locking pawl being displaceable arranged within pawl bore 50.
When the cylinder lock 20 is manipulated by the key 44, the locking pawl is displaced from a first position, where the locking pawl 46 is engaged within a locking pawl recess 54 formed in the inner surface of the neck pore 18, to a second position, where the locking pawl 46 is out of engagement with the locking pawl recess 54, which enables the cylinder lock to be displaced in the second longitudinal direction 58.
The cylinder lock 20 further comprises a release pawl 48 arranged in a second pawl bore (not shown). The release pawl 48 is spring biased arranged within the cylinder lock 20 and projects into engagement with a longitudinal release groove 52 arranged in the inner surface of the neck pore 18. When the release pawl 48 engages the release groove 52, the displaceable movement of the cylinder lock 20 is limited between two end positions defined by the longitudinal extension of the release groove 52 in the second longitudinal direction. By disengaging the release pawl 48, e.g. by pressing the release pawl 48 with a suitable tool such a thin needle, via a small opening in the upper handle neck portion 14, the cylinder lock may be removed out of the upper handle neck portion 14. In Fig. 4B is clearly illustrated how the lock pin 34 is spring biased with the lock pin spring 36 and extending through seat bore 26 of the handle neck seat 24 and being engaged within the lock hole 32 of the escutcheon 28.
Figs. 5A and 5B show a partly cross-sectioned perspective upper view and a partly cross-sectioned perspective side view of the handle 10 being unlocked, where Fig. 5B is similar to Fig. 4B.
In Fig. 5A is illustrated the manipulation of the cylinder lock 20, by the rotational movement of the key 44 in a clockwise direction. By rotating the key 44, the locking pawl 46 is moved as indicated by an arrow out of engagement with the locking pawl recess, allowing the cylinder lock to be displaced in relation to the neck bore 18.
The release pawl 48 is still in engagement with the release pawl groove 52, delimiting the movement of the cylinder lock 20 between the two end positions.
Figs. 6A and 6B show a partly cross-sectioned perspective upper view and a partly cross-sectioned perspective side view of the handle 10 in an unlocked position.
In the embodiment illustrated in Figs. 6A and 6B, the cylinder lock 20 has been manipulated by the rotation of the key 44. The locking pawl 46 is hereby disengaged from the locking pawl recess and the cylinder lock 20 is moved in a direction as indicated by the arrows, by the biasing force or the lock cylinder spring (shown in fig. 3).
As shown in Fig. 6B, the head of the lock pin 34 abuts against the lower surface of the cylinder lock 20 and the lock pin 34 is, as illustrated in the blow-up of Fig. 6A, brought out of engagement with the lock hole 32 when the cylinder lock is displaced.
