Description

Technical Field

[0001] This disclosure relates to an accessory for openable components such as doors, lockers, hatches, and windows, and an openable component including an image of a hole adapted in shape and size to receive the accessory. Background Technology

[0002] In existing technology, fittings (such as handles or hinges) are conventionally secured to openable components such as doors, lockers, hatches, and windows using attachment devices (such as screws or nuts and bolts). While this allows the fittings to be fastened to the openable component satisfactorily, the installation process is somewhat time-consuming because the attachment devices need to be tightened individually. Power tools can be used instead of hand tools such as wrenches or screwdrivers. However, power tools are typically heavy, and carrying them back and forth to the installation location is cumbersome.

[0003] Furthermore, attachment devices can introduce weaknesses in both structural integrity and security. First, the structural integrity of the attachment device may degrade over time due to wear and tear. Second, the attachment device can be disassembled to allow unauthorized access via the openable element.

[0004] Another issue is that some openable components are either left-handed or right-handed, and accessories are typically designed to be installed into these components in a specific way. Accessories are not usually designed to be reconfigured after assembly to install into other such openable components. Accessories with this capability often have complex structures with many moving parts of varying sizes, making them relatively brittle.

[0005] Therefore, it is of interest to provide a new accessory that addresses at least some of the problems identified in the prior art. Summary of the Invention

[0006] The object of this invention is to provide an improved solution that mitigates at least some of the aforementioned disadvantages of existing solutions. In particular, a first object of the invention is to provide an accessory that is easy to install into an openable component. A second object of the invention is to provide an accessory that makes unauthorized access difficult. These objects are achieved by the invention as defined in claim 1.

[0007] A third object of the present invention is to provide an accessory that can be reconfigured after assembly for right-hand or left-hand operation of an openable component.

[0008] Furthermore, a fourth objective is to provide an openable element having a hole image that is adapted in shape and size to receive the accessories of the present invention.

[0009] "Accessories" can refer to the arrangement of handles, locks, hinges, etc.

[0010] "Openable element" can refer to doors, lockers, hatches, windows, etc. An openable element can be configured to pivot between an open position and a closed position. An openable element can also be configured to slide between an open position and a closed position.

[0011] "Right-hand operation" can refer to the opening of an openable element, as seen when the accessory is positioned on the side facing the openable element, and the openable element opens to the right via a pivoting or sliding motion.

[0012] "Left-hand operation" can refer to the opening of an openable element, as seen when the accessory is positioned on one side of the openable element, by a pivoting or sliding motion, opening to the left.

[0013] Alternatively, the openable element can be configured to open vertically via pivoting or sliding motion, i.e., opening in the upward or downward direction. The accessories of the present invention can also be used for such an openable element.

[0014] According to a first aspect of the invention, an accessory is provided for an openable element, such as a door, locker, hatch, or window. The accessory includes: a housing configured to be disposed on one side of the openable element; a shaft extending from the housing and configured such that, when the accessory is disposed to the openable element, the shaft extends through a hole pattern of the openable element; and an actuating member disposed on the shaft and rotatable relative to the housing. The accessory further includes a fixing member axially disposed between the housing and the actuating member along the shaft, such that the fixing member is rotatable relative to the housing and the shaft between an insertion position and a first fixed position in which the fixing member rotates in a first rotational direction. When the accessory is disposed to the openable element, the insertion position allows the fixing member and the actuating member to be inserted into the hole pattern of the openable element. In the first fixed position, the fixing member engages with a fixing protrusion extending from the housing through the hole pattern during use, such that the accessory is secured to the openable element by compressive force.

[0015] This accessory can be securely attached to an openable element without the use of attachment devices such as screws, nuts, and bolts. Instead, the accessory is configured to be securely attached to the openable element by means of a retaining member and a retaining protrusion, which together allow the accessory to be secured to the openable element under compressive force. In other words, the accessory is provided with pre-installed attachment devices during assembly. This achieves a tool-free installation process. Therefore, the accessory is easy to install to the openable element, thereby solving the first objective of the invention.

[0016] "Securing the fitting to the openable element by applying compressive force" can mean that the fixing member, when in a fixed position, interacts with the fixing protrusion, causing the fixing member to be axially offset relative to the axis by an axial offset distance. This movement pulls the housing toward the mounting surface of the openable element. The offset distance can be approximately 0.1 mm to 0.2 mm, 0.2 mm to 0.3 mm, 0.3 mm to 0.4 mm, 0.4 mm to 0.5 mm, 0.5 mm to 0.6 mm, 0.6 mm to 0.7 mm, 0.7 mm to 0.8 mm, 0.8 mm to 0.9 mm, or 0.9 mm to 1.0 mm.

[0017] Throughout this disclosure, tolerances are assumed to be about 1% to 2%, 2% to 3%, 3% to 4%, or 4% to 5% relative to specified values.

[0018] Furthermore, by moving the actuating member in the opposite direction, the fixing member can be rotated from the fixed position to the insertion position. This also makes the fitting easy to remove from the openable component.

[0019] The side of the openable component onto which the fitting is arranged can be referred to as the mounting side. Typically, the mounting side of the openable component is characterized by its mounting plane. The fitting can be configured to be arranged onto the mounting plane such that its axis extends substantially perpendicular to the mounting plane. Therefore, the retaining member can be configured to rotate in a plane parallel to the mounting plane.

[0020] The shaft may define a first axis of rotation, about which the fixing member is configured to rotate. As seen when facing the side of the openable element on which the accessory is positioned, the first direction of rotation may be clockwise about the first axis of rotation. Alternatively, as seen when facing the side of the openable element on which the accessory is positioned, the first direction of rotation may be counterclockwise about the first axis of rotation. The direction of the first direction of rotation may be selected depending on whether the accessory is to be positioned on a right-handed or left-handed openable element.

[0021] The hole image may include an insertion hole through which the actuating member and the retaining member can be inserted when in the insertion position. The hole image may include one or more retaining protrusion holes through which a retaining protrusion of the housing can extend. Some or all of the insertion hole and the corresponding one or more retaining protrusion holes may be connected via a slot or not connected at all.

[0022] The actuating member can be a joystick. The joystick can be configured to be accessible from one side of the openable element, opposite to the side of the openable element on which the fitting is arranged. The actuating member can be rotated relative to the housing by means of rotation of a shaft.

[0023] When the accessory is a handle arrangement, the actuating member can be, in particular, a cam member. The cam member can be configured to move between a locked position and an unlocked position, in which the cam member extends to engage with a frame plate disposed to the frame of the openable element, and in the unlocked position, the cam member retracts to allow the openable element to be opened.

[0024] The shaft can be configured with multiple axial segments.

[0025] The first shaft portion may be an end portion. The first shaft portion may be configured in shape and size to be interlocked with the actuating member in a rotational sense. This can be achieved by the following: the first shaft portion may have at least a first pair of parallel sides in the axial section. The shaft may have two pairs of parallel sides in the axial section. The actuating member may include a recess or through-hole adapted in size and shape to receive the first shaft portion, such that the actuating member is interlocked with the shaft in a rotational sense.

[0026] The second shaft portion can be an intermediate section. The second shaft portion can be adjacent to the first shaft portion. The second shaft portion can be configured in shape and size to allow the fixing member to rotate freely relative to the second shaft portion. The second shaft portion can have a circular axial cross-section. The second shaft portion can have a cylindrical shape. The second shaft portion can include two cylindrical portions with a groove arranged between them. The groove can be configured to receive a rubber washer. The rubber washer can be configured to provide friction to the fixing member as it rotates.

[0027] The third shaft portion can be an end portion. The third shaft portion can be adjacent to the second shaft portion. The third shaft portion can be configured in shape and size to be axially connected to the housing, but is allowed to rotate relative to the housing.

[0028] The actuating member can be axially secured to the shaft by means of a screw configured to engage a groove in a bore that at least partially extends through the shaft. In the case of a handle arrangement, the bore can be a through-hole, and the screw can be configured to extend through the shaft and engage a groove in the handle's bore, thereby axially securing the handle relative to the shaft in a rotational sense. The third shaft portion can further include a plurality of handle engagement grooves for receiving a handle connecting member within the grooves, thereby increasing support and further axially securing the handle relative to the shaft in a rotational sense.

[0029] The first, second, and third shaft portions can be axially fixed relative to each other in a rotational sense. The first, second, and third shaft portions can be formed as a single integral component.

[0030] According to an embodiment, the fixing member can be configured to rotate between an insertion position and a first fixed position by means of an actuating member. Because the actuating member can be used to actuate the fixing member to rotate between the insertion position and the first fixed position, and because the actuating member can also be inserted through the hole image, it cannot be accessed from the same side of the openable element on which the accessory is arranged. Therefore, this design allows the fixing member to be prevented from being rotated to the insertion position from the side of the openable element on which the accessory is arranged, thus preventing the accessory from being removed from the openable element. This prevents unauthorized access to the openable element, thus achieving the second objective of the invention.

[0031] According to one embodiment, the fixing member can further rotate between an insertion position and a second fixed position in which the fixing member rotates in a second rotational direction opposite to the first rotational direction. In the second fixed position, the fixing member engages with a fixing protrusion extending from the housing through the hole image, such that the fitting is secured to the openable element by compressive force.

[0032] Thus, the accessory can be reconfigured for placement in a right-hand or left-hand operating openable element, thereby achieving the third objective of the invention.

[0033] Similarly, the accessory can be reconfigured to openable elements in either the upward or downward direction.

[0034] According to one embodiment, the fixing member can be configured to rotate between an insertion position and a second fixing position by means of an actuating member.

[0035] According to one embodiment, the fixing member includes an axial protrusion that extends only partially in the circumferential direction about an axis, through which the fixing member engages with the actuating member.

[0036] Thus, the actuating member can be pushed against the fixed member, such that when the actuating member rotates from the insertion position in the first direction, the fixed member is also forced to rotate in the same direction. Once the actuating member has forced the fixed member into a fixed position, the actuating member can rotate freely in the opposite direction for different purposes. For example, when the accessory is a handle arrangement, the actuating member can be a cam member. When the fixed member is in a fixed position, the cam member can rotate freely between a locked position and an unlocked position without engaging with the fixed member. The cam member can be configured to rotate between the locked and unlocked positions by rotating the handle arranged to the shaft, thereby also forcing the cam member to rotate.

[0037] Furthermore, when the fixing member can be rotated to two different fixed positions, the axial protrusion, which extends only partially in the circumferential direction around the axis, allows for a free range of motion of the actuating member, regardless of whether the fixing member is moved to the first or second fixed position. Furthermore, the actuating member can be easily rotated in a direction that forces the fixing member from the fixed position to the insertion position, thus providing an easy way to remove the fitting from the door, even when designed to be reconfigurable between right-handed and left-handed operation.

[0038] According to one embodiment, the axial protrusion is arc-shaped, preferably having an arc length of about 75 to 105 degrees, preferably about 90 degrees. This particular shape is advantageous because it achieves good contact between the actuating and fixing members when the fixing member rotates between the intermediate and fixed positions. Furthermore, this particular shape is relatively easy to manufacture when the actuating member comprises a main cylinder, as it essentially involves only cutting a piece from the end of the cylinder of the fixing member. The specified preferred arc length is particularly advantageous when the fitting is designed to be reconfigurable between right-handed and left-handed use.

[0039] According to one embodiment, the retaining member includes one or more flanges configured to engage with an internal recess in the housing, the retaining member being axially secured to the housing via these flanges. When the retaining member moves from an insertion position to a fixed position, the flanges press against the recess, thereby forcing the housing toward the mounting plane of the openable element. Furthermore, in cases where retaining protrusions form part of the housing, these protrusions are pushed through a hole in the openable element, thereby enabling the fitting to be secured to the openable element under compressive force.

[0040] The internal groove may extend circumferentially along the inner surface of the housing, partially or entirely around the center for receiving the shaft. There may be two or more flanges. In the case of only two flanges, these two flanges may be arranged on radially opposite sides of the fixing member.

[0041] The housing may be adapted in shape and size such that the hole for receiving the shaft has a slot for axially receiving the flange of the fixing member during assembly.

[0042] Flanges may have beveled end surfaces that are configured to face grooves in the housing. This facilitates engagement between the flange of the fixing member and the groove in the housing.

[0043] According to one embodiment, the fixing member further includes a main cylinder and at least one radial portion extending from the main cylinder, through which the fixing member engages with a fixing protrusion corresponding to a first fixing position. Thus, the cross-sectional shape of the fixing member still allows it to be inserted into the main hole of the hole image of the openable element, while also reaching the fixing protrusion positioned off-center from the main hole of the hole image. Furthermore, the radial portion can provide a large contact surface, thereby providing support for the fitting when it is fixed to the openable element under compressive force. The at least one radial portion can extend in a direction substantially perpendicular to the longitudinal extension direction of the main cylinder. The longitudinal extension direction of the main cylinder can be aligned with the longitudinal extension direction of the shaft.

[0044] According to one embodiment, the fixing member further includes at least two radial portions extending radially from two opposite sides of the main cylinder, through which the fixing member engages with a corresponding fixing protrusion corresponding to one of the fixing positions. This adds support on opposite sides relative to the axis, thereby allowing the fixing member to be more securely secured to the door.

[0045] According to one embodiment, at least one of the at least radial portions includes a retaining recess for receiving the retaining protrusion, wherein the retaining recess is adjacent to the raised region, so that when the retaining protrusion is being received into the retaining recess, the at least one radial portion temporarily flexes away from the retaining protrusion. Thus, the retaining protrusion and the retaining member can be engaged unless the torque on the retaining member exceeds a predetermined amount sufficient to displace the retaining member from the retaining protrusion. Therefore, accidental displacement of the retaining member from the retaining protrusion can be prevented when the openable element and / or fitting is subjected to a force impact.

[0046] According to one embodiment, the raised region gradually tapers in the radial vertical direction away from the fixing recess. This allows the fixing member to be inserted into the fixing position more easily.

[0047] According to one embodiment, the fixing member includes one or more support portions extending between the main cylinder and each of at least one radial portion. The support portions can prevent the radial portions from excessively deflecting when interacting with the fixing protrusion.

[0048] According to one embodiment, when rotating between the insertion position and the first fixed position and / or between the insertion position and the second fixed position, the rotation angle of the fixing member is approximately 90 degrees. This maximizes the contact surface between the fixing member and the inner surface of the openable door. Furthermore, structural symmetry is provided between right-handed and left-handed operation, thereby ensuring that the structural integrity of the device remains the same regardless of whether the accessory is configured for right-handed or left-handed operation.

[0049] According to one embodiment, the accessory further includes a push-button cylinder lock coupled to the shaft, and configured to be received in a push-button cylinder lock recess in the housing when in a locked position, regardless of whether the fixing member is moved to a first fixed position or a second fixed position. Thus, the shaft can be fixed to the housing in a rotational sense, thereby preventing rotation of the shaft relative to the housing, and thus preventing rotation of the actuating member. Furthermore, in the case of a handle arrangement, the push-button cylinder lock can be used to lock an openable element to prevent it from being opened, regardless of whether the openable element is configured for right-hand or left-hand operation. The push-button cylinder lock can be coupled to the shaft via a radially extending shaft portion including a recess for receiving the push-button cylinder lock. The radially extending shaft portion can extend from a third shaft portion of the shaft. Similarly, in the case of a handle arrangement, the handle can have an opening through which the push-button cylinder lock can be operated.

[0050] According to one embodiment, the accessory further includes a rotation stop block rotatably connected to the actuating member and configured to slide along a predetermined groove in the housing, the length of which substantially corresponds to half a turn of the actuating member. This prevents the shaft from rotating relative to the housing beyond a certain angle. The rotation stop block may be a radially extending protrusion from the shaft. Alternatively, the rotation stop block may be a radially extending protrusion from a third shaft portion. The third shaft portion may have a substantially cylindrical shape, and the rotation stop block may extend radially from the cylindrical surface. The rotation stop block may be disposed on the side of the shaft opposite to the radially extending shaft portion, which includes a recess for receiving a push-button cylinder lock.

[0051] According to one embodiment, the push-button cylinder lock recess for receiving the push-button cylinder lock is located at the midpoint of an arc extending between the endpoints of the recess in the housing on the side of the shaft opposite to the predetermined groove.

[0052] According to a second aspect of the invention, an openable element is provided. The openable element includes a hole image of size and shape adapted to receive a fitting according to the first aspect or any embodiment thereof. Preferably, the openable element includes the fitting. The hole image may include a main hole configured to allow insertion of an actuating member and a fixing member in an inserted position. The main hole may have an elongated shape. The main hole may have a rectangular shape. The hole image may include a fixing protrusion hole positioned adjacent to the main hole. The hole image may include two fixing protrusion holes arranged on opposite sides of the main hole. The shape of one or more fixing protrusion holes may correspond to the cross-sectional shape of the fixing protrusion. In the case where the fixing protrusion has a circular cross-section, the one or more fixing protrusion holes may be circular holes.

[0070] The invention will now be described more fully with reference to the accompanying drawings, in which preferred embodiments of the invention are illustrated. However, the invention can be implemented in many 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. In the drawings, the same reference numerals refer to the same elements.

[0071] According to one embodiment of the invention, the accessory is configured to be arranged in an openable element such as a door, locker, hatch, or window. Figure 1a and Figure 1b In this case, accessory 1 is installed onto the mounting surface of the openable element (door 100 in this case). Figure 1a In the middle, the fittings are arranged to a door 100 configured for left-hand operation, meaning the door opens to the left. Figure 1b In this configuration, accessory 1 is placed onto a door 100 that is set for right-hand operation, meaning the door opens to the right. Accessory 1 can be configured as a handle arrangement 1 or a hinge arrangement 1*, such as... Figure 1a and Figure 1b As indicated in the image. The openable element 100 (in this case, a door) is adapted to have a hole 110 for receiving the fitting 1.

[0072] Figures 2 to 5The image shows a fitting 1 according to one embodiment, which is implemented as a handle arrangement. According to one embodiment, fitting 1 includes a housing 2 configured to be disposed on one side of the openable element 100. Fitting 1 includes a shaft 7 extending from the housing 2, and the shaft is configured such that when fitting 1 is disposed to the openable element 100, the shaft 7 extends through a hole image 110 in the openable element 100. Fitting 1 further includes an actuating member 5 disposed on the shaft and rotatable relative to the housing 2. Accessory 1 further includes a retaining member 4 axially arranged between housing 2 and actuating member 5 along shaft 7, such that retaining member 4 is rotatable relative to housing 2 and shaft 7 between two positions: an insertion position, which allows retaining member 4 and actuating member 5 to be inserted into hole pattern 110 when the accessory is being arranged into the openable element 100; and a first fixed position in which retaining member 4 is rotated in a first rotational direction, in which retaining member 4 engages with a retaining protrusion 21 extending from housing 2 through hole pattern 110, thereby securing accessory 1 to the openable element 100 under compressive force. Retaining member 4 is configured to be rotatable between the insertion position and the first fixed position by means of actuating member 5.

[0073] When assembling accessory 1 to openable component 100 (e.g., ... Figure 1a and Figure 1b When the door shown is in use, accessory 1 is configured such that the fixing member 4 is positioned in the insertion position. In this position, the fixing member 4 and the actuating member 5 can be inserted together into the hole image 110, specifically through the insertion hole 111 of the hole image 110. Figure 1a and Figure 1b In the hole image 110, the insertion hole 111 is a rectangular opening. Furthermore, when the accessory 1 is arranged to the openable element 100, retaining protrusions 21 are also placed in the hole image, specifically such that these retaining protrusions extend through corresponding retaining protrusion holes 112. The corresponding retaining protrusions are arranged on opposite sides of the insertion hole 111. Figure 1a and Figure 1b In the image 110, there are two fixed protruding holes 112 arranged symmetrically about the insertion hole 111.

[0074] Therefore, when the fixing member 4 is rotated from the insertion position to the fixed position by means of the actuating member 5 (in which the fixing member 4 engages with at least one fixing protrusion 21), the fitting 1 is securely fixed to the openable element.

[0075] Therefore, accessory 1 can be securely attached to the openable component without the use of attachment devices such as screws, nuts, and bolts. This enables a tool-free installation process. Consequently, the accessory is easy to install onto the openable component.

[0076] Figure 2 A front view of accessory 1 according to an embodiment of the present invention is shown. Figure 3 A front perspective view of accessory 1 according to the same embodiment is shown.

[0077] In this particular embodiment, accessory 1 is a handle arrangement, wherein the actuating member 5 is a cam member configured to operate between a locked position and an unlocked position by means of a handle 3 connected to the cam member 5 via a shaft 7. In the locked position, when accessory 1 is arranged to openable element 100, cam member 5 engages with the frame plate to hold openable element 100 in a locked state. In the unlocked position, cam member 5 does not engage with the frame plate, thereby allowing openable element 100 to be opened.

[0078] Furthermore, accessory 1 includes a push-button cylinder lock 6, which is operable between a locked state and an unlocked state. In the locked state, the push-button cylinder lock 6 engages with the housing 2, thereby locking the handle 3 relative to the housing 2 in a rotational sense. In the unlocked state, the push-button cylinder lock 6 is not engaged with the housing 2, such that the handle 3 is locked to the housing 2 in a rotational manner. The push-button cylinder lock 6 can be moved between the locked and unlocked states by first pressing it toward the housing 2 and then rotating it about its axis. Although not shown, the push-button cylinder lock 6 can be configured to be moved between the locked and unlocked states only by means of a key.

[0079] Figure 4 A rear perspective view of accessory 1 according to an embodiment of the present invention is shown. Figure 5 A rear view of the fitting according to the same embodiment is shown. In these figures, the retaining member 4 is in the insertion position, meaning that the retaining member is in a position where it can be inserted through the hole in image 110. When the actuating member 5 (in this case, the cam member) is rotated counterclockwise about the rotation axis R, the retaining member 4 is actuated and also rotates about the rotation axis R from... Figure 4 The insertion position shown is rotated to the fixed position, in which the fixing member 4 engages with the corresponding fixing protrusion 21 extending from the housing 2 via the radial portion 43.

[0080] Accessory 1 can also be configured such that the retaining member 4 is further rotatable between an insertion position and a second position in which the retaining member 4 rotates in a second rotational direction opposite to the first rotational direction. In this second position, the retaining member 4 engages with a retaining protrusion 21 extending from the housing 2 through the hole image 110, thereby subjecting accessory 1 to compressive force and securing it to the openable element. The retaining member 4 is configured to rotate between the insertion position and the second fixed position by means of the actuating member 5. This allows the accessory to be reconfigured for the openable element regardless of whether the openable element is configured for right-hand or left-hand operation. Figure 4 In this process, the actuating member 5 (in this case, a cam member) is rotated clockwise about the rotation axis R, causing the actuating member 5 to engage with the fixed member 4 from the opposite direction, thereby reaching a second fixed position. The fixed member 4 includes an axial protrusion 41 that extends only partially in the circumferential direction about the shaft 7, through which the fixed member engages with the actuating member 5. Figure 4 As shown, the actuating member 5 (in this case, the cam member 5) engages with the fixed member 4 when rotating counterclockwise, but rotates freely in the opposite direction (until the actuating member engages with the fixed member 4 from the opposite direction). The axial protrusion 41 is arc-shaped. The axial protrusion 41 is arc-shaped such that its curvature corresponds to the central rotating portion of the actuating member 5. The arc length of the arc-shaped axial protrusion 41 is approximately 90 degrees. Regardless of whether the actuating member 5 rotates counterclockwise or clockwise, the actuating member will engage with the axial protrusion 41 during its rotation, thereby causing the fixed member 4 to rotate by means of the actuating member 5.

[0081] Therefore, accessory 1 can be reconfigured for placement in a right-hand or left-hand operating openable element 100.

[0082] In addition, such as Figure 4 and Figure 5 As shown, the fixing member 4 further includes a main cylinder 42 and two radial portions 43 extending from the main cylinder 42 in opposite directions. The fixing member 4 can engage with a corresponding fixing protrusion 21 via the radial portions 43. When the fixing member 4 engages with the fixing protrusion 21, the fixing member is in a fixed position. (As shown in...) Figure 4 As can be seen, the fixing member 4 can be rotated to a first fixed position and a second fixed position. The second fixed position corresponds to the orientation of the fixing member 4 when it is in the first fixed position, but is rotated 180 degrees. These two fixed positions correspond to two different configurations associated with the openable element, which are configured for right-handed or left-handed operation.

[0083] The fixing member 4 further includes a support portion 44 extending between the main cylinder 42 and the radial portion. These support portions provide support for the radial portion 43, thereby preventing the radial portion from deflecting excessively away from the fixing protrusion when interacting with the fixing protrusion 21.

[0084] Furthermore, when rotating between the insertion position and the first fixed position, the rotation angle of the fixing member 4 is approximately 90 degrees. When rotating between the insertion position and the second fixed position, the rotation angle of the fixing member 4 is also approximately 90 degrees.

[0085] like Figure 10 As shown, each of the radial portions 43 includes a retaining recess 431 for receiving the retaining protrusion 21 when the retaining member 4 is rotated to a fixed position. The retaining recess 431 is adjacent to the raised region 432, thereby causing the radial portion 43 to temporarily flex away from the retaining protrusion 21 while the retaining protrusion 21 is being received in the retaining recess 431. These retaining recesses 431 are shown in detail in... Figure 10 It is circular in shape. Furthermore, the raised region 432 gradually tapers in the radial vertical direction away from the fixed recess 431.

[0086] Figure 6 A top view of accessory 1 according to one embodiment is shown, wherein the handle is omitted in the view. Accessory 1 further includes a rotation stop 22 rotatably coupled to an actuating member 5 and configured to slide along a predetermined groove 24 in the housing 2, the length of which substantially corresponds to half a turn of the actuating member 5. The rotation stop 22 is coupled to a shaft 7, thereby preventing the shaft 7 from rotating freely beyond the range of rotation defined by the groove 24. Thus, the actuating member 5 (in this case, a cam member) and the handle are also limited to the same range of rotation as the shaft. However, the groove 24 can be adapted to extend differently around the shaft, thereby defining different ranges of rotation for the shaft. Therefore, the feature of limiting the shaft to half a turn is optional.

[0087] As previously explained, accessory 1 according to one embodiment further includes a push-button cylinder lock 6. The push-button cylinder lock 6 is coupled to the shaft 7 and is configured to be received in the push-button cylinder lock recess 23 of the housing 2 when in the locked state, regardless of whether the fixing member 4 is moved to a first fixed position or a second fixed position. Figure 6 As shown, the push-button cylinder lock recess 23 for receiving the push-button cylinder lock 6 is located at the midpoint of the arc extending between the endpoints of the recess 24 in the housing 2 on the side of the shaft 7 opposite to the predetermined groove 24. Although in Figures 9 to 11Not shown, but the push-button cylinder lock recess 23 includes a slot extending into the cylindrical wall surface, which is configured to receive the push-button cylinder lock member when the push-button cylinder lock is rotated to the locked state. This allows the push-button cylinder lock 6 to remain in the locked state, which would otherwise be moved to the unlocked state by means of a coil spring (not shown).

[0088] Figure 7 A perspective view of the shaft 7 of accessory 1 according to an embodiment of the present invention is shown. Figure 8 A side view of shaft 7 according to the same embodiment is shown. Shaft 7 includes a first shaft portion 71 for engaging with actuating member 5. Shaft 7 includes a second shaft portion 72 for providing a surface along which fixing member 4 can slide when the fixing member rotates about the shaft. Shaft 7 includes a third shaft portion 73 for axially fixing shaft 7 to housing 2 while allowing the shaft to still rotate relative to housing 2. The second shaft portion 72 is axially arranged between the first shaft portion 71 and the third shaft portion 73. A rotation stop block 24 is arranged to the third shaft portion. Shaft 7 further includes a radially extending shaft portion 74 including a recess for receiving a push-button cylinder lock 6. The first shaft portion 71 has two pairs of parallel sides in axial section. These two pairs of parallel sides allow actuating member 5 to be fixed relative to shaft 7 in a rotational sense. The second shaft portion 72 includes two cylindrical portions with a groove arranged between the two cylindrical portions for retaining a rubber gasket 75. The rubber washer 75 is configured to provide friction to the fixed member 4 as the fixed member 4 rotates.

[0089] As in Figures 9 to 11 As can be seen, the fixing member 4 includes two flanges 45 arranged on opposite sides of the main cylinder 42. These flanges 45 are configured to engage with the internal grooves 25 of the housing 2, through which the fixing member 4 is axially fixed to the housing 2 relative to the shaft 7. Except for two open sections arranged opposite to each other, the internal grooves 25 extend substantially along the inner surface of the housing 2 completely around the shaft 7. These two open sections are configured to define the path of movement of the flanges 45 during assembly when the fixing member 4 is inserted into the housing 2. The internal grooves 25 and the predetermined grooves 24 are offset relative to each other in a direction parallel to the axis of rotation defined by the shaft 7.

[0090] Figure 12 and Figure 13 The accessory 1 according to one embodiment is shown. In both figures, the fixing member 4 is in a fixed position. However, the actuating member 5 (in this case, the cam member) is... Figure 12 In the unlocked position, while Figure 13The cam member 5 is in the locked position. It can rotate between the locked and unlocked positions via a handle 3 connected to the cam member 5 by means of a shaft 7. Figure 4 Starting from the position in the middle, the cam component 5 is as follows: Figure 4 The counterclockwise rotation seen in the image causes the cam component 5 to push the fixed component 4 to... Figure 12 The fixed position shown allows the fixing member to engage with the fixing protrusion 21 of the extended through-hole image 110 of the housing 2. After the fitting 1 is secured to the openable element 100 by the fixing member 4 in the fixed position, the cam member 5 can be released from... Figure 13 The position shown is operated in either a clockwise or counterclockwise direction to reach the open position, thereby opening the openable element 100.

[0091] Preferred embodiments and examples of the invention have been disclosed in the accompanying drawings and description, and although specific terminology has been used, it is used in a general and descriptive sense only and not for limiting purposes, and the scope of the invention is set forth in the appended claims.
