[0034] Example 1

[0035] Reference Figures 1 to 7 As shown, a door and window that can be opened in opposite directions comprises: a window frame 1, fixedly connected to a wall; a window sash 2, openably connected to the window frame 1, the window sash 2 comprises a sash frame 22 and glass, preferably, the glass is hollow glass, which has better heat insulation and sound insulation performance; at least two connecting pieces, which have a left opening state and a right opening state, and the window sash 2 is connected to the window frame 1 through the connecting piece; and a control handle 3, which is arranged on the window sash 2 or the window frame 1, preferably, the control handle 3 is arranged on the window sash 2; wherein, the control handle 3 can control the state switching of the connecting piece, so that the two opposite sides of the window sash 2 can be opened selectively. Specifically, this embodiment can be set to open in the upper, lower, left, or right directions according to needs, and only one direction can be selected to open when opening.

[0036] Compared with existing doors and windows that only support single-side opening, this embodiment provides a design solution that can be opened in opposite directions. This design allows users to flexibly choose the side of the door and window to open according to the actual use environment. For example, users can choose to close the windward side and open the leeward side to reduce the impact of wind pressure on the door and window; or choose to open the other side when the air intake is too large or too small; or choose to open the side according to the actual situation when privacy is required, thereby improving the flexibility and convenience of use.

[0037] The connecting member may be a sliding support 4 or a hinge. If the connecting member is a sliding support 4, a left and a right sliding support 4 may be respectively arranged at the upper and lower ends of the window sash 2. Preferably, the left and the right sliding supports 4 are symmetrically arranged at the two ends of the window sash 2. When the window sash 2 needs to be opened to the left, the right sliding support 4 is controlled by the control handle 3 to lock the connection with the window sash 2, and the left sliding support 4 is controlled to be disconnected from the window sash 2. In this state, the window sash 2 can be opened to the left in the left opening state of the connecting member; if the window sash 2 needs to be opened to the right, the window sash 2 needs to be closed first, and then the state of the connecting member is switched by the control handle 3, so that the connecting member is switched to the opposite state of the left opening, and the window sash 2 can be opened to the right. It can be understood that the left and right sliding supports 4 can share a support rod 41 and a window edge rod 42, that is, the left and right sliding supports 4 are designed as one sliding support 4; the control handle 3 may be one or two. When the control handle 3 is two, the left and right sliding supports 4 are controlled respectively.

[0038] In some embodiments, the number of the control handle 3 is one, and the control handle 3 can control the opening of the window sash 2 in two directions. The control handle 3 controls the connection state between the left and right sliding supports 4 and the window sash 2 through different gears. In order to facilitate the opening of the window sash 2 in two directions, a fixed handle can be set on the side where the control handle 3 is not set, that is, the control handle 3 switches the state of the connecting piece, and then the window sash 2 is pushed outward by the control handle 3 or the fixed handle to complete the window opening operation.

[0039] In some embodiments, the control handle 3 has three control gears: locked, one-side open, and the other-side open. In this embodiment, a control handle 3 that can switch gears in forward and reverse directions (forward and reverse directions refer to clockwise and counterclockwise rotation) can be selected. When the control handle 3 is in the locked gear, the control handle 3 is rotated clockwise to switch to the gear position of one-side open, and the one side of the embodiment is controlled to be opened; when the control handle 3 is in the locked gear, the control handle is rotated counterclockwise to switch to the gear position of the other side open, and the other side of the embodiment is controlled to be opened.

[0040] In some embodiments, the connecting member includes a left connecting member and a right connecting member, and one end of the connecting member is fixedly connected to one of the window sash 2 or the window frame 1, and the other end of the connecting member is connected to the other of the window sash 2 or the window frame 1 through a detachable structure. Preferably, the connecting member is fixedly connected to the window frame 1, and the connecting member is connected to the window sash 2 through a detachable structure.

[0041] The detachable structure has a detached position and a connected position, and the control handle 3 can control the connection member to be detached from / connected to the window frame 1 or the window sash 2. Specifically, if the left connection member of the window sash 2 is in the detached position and the right connection member is in the connected position, the window sash 2 can be opened on one side of the left connection member, that is, the window sash 2 can be detached from the left connection member, and the window sash 2 can be opened by the connection support with the right connection member. By switching the gear position of the control handle 3, the opening of the other side can be realized.

[0042] In some embodiments, a locking member 5 is further included. The locking member 5 is multiple and is provided at least on two opposite sides of the window sash 2 and the window frame 1. Preferably, the locking member 5 is provided on two opposite sides and is symmetrically provided at both ends of a single side. The locking member 5 includes a locking point 51 fixedly connected to the window frame 1 and a locking column 52 movably provided on the window sash 2. When the window sash 2 is in a closed state, the locking column 52 is locked with the locking point 51; when the window sash 2 is in an open state, the locking column 52 is disengaged from the locking point 51. The locking column 52 is columnar. When the window sash 2 is in a closed state, the locking column 52 protrudes toward the window frame 1. The locking point 51 is fixedly connected to the window frame 1 and is provided with a locking block 53 extending toward the locking column 52. The locking block 53 is provided on the outer side of the locking column 52 and has an inwardly concave arc surface. When the window sash 2 is in a closed state, the locking block 53 can restrict the window sash 2 from opening. When it is necessary to open this embodiment, the handle 3 can be controlled to switch to the opening position (the position on one side or the other side). At this time, the lock column 52 is driven by the transmission member, the lock column 52 is dislocated from the lock point 51, and the window sash 2 can be pushed outward to open.

[0043] In some embodiments, the connecting member is a sliding support 4, and the sliding support 4 is provided with a detachable structure, and the sliding support 4 is respectively arranged at both ends of the bottom and / or top of the window sash 2. In this embodiment, the connecting member is arranged at the bottom and top of the window sash 2, and sliding supports 4 are respectively arranged at both ends of the bottom and top, which can be divided into a left sliding support 4 and a right sliding support 4, and both the left and right sliding supports 4 are provided with a detachable structure. In this embodiment, the sliding support 4 can be selected according to actual needs to select different opening angles to adapt to different climate conditions and usage habits.

[0044] [Slide support 4]

[0045] Reference Figure 5As shown, the sliding support 4 includes a window edge rod 42 connected to the window frame 1, and a supporting rod 41 connected to the window sash 2, and a hinge connection is connected between the supporting rod 41 and the window edge rod 42, wherein the window edge rod 42 or the supporting rod 41 is provided with a detachable structure, and the detachable structure includes a locking portion 43 and a detaching portion 44, and the detachable structure can be locked / disconnected with the window frame 1 or the window sash 2. In this embodiment, the detachable structure is arranged on the supporting rod 41, and the supporting rod 41 can be locked / disconnected with the window sash 2. The supporting rod 41 has a bending portion 45 arranged along its own length direction, and the bending portion 45 can strengthen the strength of the supporting rod 41. Specifically, the window sash 2 has a clamping column 21, and the clamping column 21 is movably arranged on the window sash 2. The clamping column 21 is controlled by switching the gear of the handle 3 to make the clamping column 21 move to the locking portion 43 or the detaching portion 44. When the clamping column 21 moves to the detaching portion 44, the sliding support 4 can be detached from the window sash 2. In this embodiment, the sliding support 4 is divided into a left sliding support 4 and a right sliding support 4, which are respectively connected to the two sides of the window sash 2. When one of the sliding supports 4 is disconnected from the window sash 2 and the other sliding support 4 is connected to the window sash 2, the window sash 2 can be pushed outward on one side to open. Similarly, the control handle 3 is used to switch the connection state between the left and right sliding supports 4 and the window sash 2, and the other side of the window sash 2 can be pushed outward to open.

[0046] The sliding support 4 of this embodiment has a detachable structure. Through this innovative design, the sliding support 4 can be easily detached from or connected to the window sash 2 or the window frame 1, thereby realizing the function that both sides of the window sash 2 can be opened independently.

[0047] In some embodiments, the detachable structure is disposed on the support rod 41. With such a design, the sliding support 4 can be detached from the window sash 2, and the sliding support 4 will not be brought out when the window sash 2 is opened outwards.

[0048] In some embodiments, there are at least two detachable structures. Such a design can enhance the connection stability between the sliding support 4 and the window sash 2, and prevent the two from becoming loose or easily detached when connected.

[0049] In some embodiments, the detachable structure is an L-shaped notch. Such a design is simple in structure, stable and reliable, and convenient for detaching from and locking with the window sash 2.

[0050] In some embodiments, the hinge connector includes: a long rod 46, one end of which is hinged to the window edge rod 42, and the other end of which is hinged to the support rod 41; a slider 49, which is slidably connected to the window edge rod 42;

[0051] The short rod 47 has one end hinged to the slider 49 and the other end hinged to the support rod 41; and the middle rod 48 has one end hinged to the middle section of the long rod 46 and the other end hinged to the slider 49. Specifically, the window edge rod 42 has a slide groove, the slider 49 is slidably connected to the slide groove, one end of the short rod 47 is hinged to the slider, and the other end of the short rod 47 is hinged to the support rod 41.

[0052] In some embodiments, the long rod 46 is staggered with the short rod 47 and the middle rod 48. The staggered arrangement ensures that the long rod 46, the short rod 47 and the middle rod 48 do not interfere with each other when they move.

[0053] In some embodiments, a gasket is provided at each hinge of the long rod 46, the middle rod 48 and the short rod 47. Such a design can reduce the friction at the hinge and extend the service life of this embodiment.

[0054] In some embodiments, in the open state, the end of the support rod 41 farther from the window edge rod 42 is provided with a limiting portion 411, and specifically, the end of the limiting portion 411 is provided with a bend, and an opening is provided in the bend. The opening cooperates with the limit lock box 6 or other limit mechanisms to limit the opening of the sliding support 4.

[0055] In some embodiments, a transmission member is also included, and the transmission member is linked to the control handle 3, and the control handle 3 controls the connecting member through the transmission member. The transmission member includes a limit link 71, a corner turner 72, a corner turner slider bar 73 and a limit bar 74. In this embodiment, the control handle 3 is arranged at the middle position of one side of the window sash 2, and the two ends of the control handle 3 are respectively connected to the transmission member, which is arranged along the edge of the sash frame 22, receives power from the control handle 3, and transmits it to the connection between the window sash 2 and the connecting member through the transmission member, so as to realize the connection / detachment of the connecting member from the window frame 1 or the window sash 2. The corner turner 72 is arranged at the corner of the sash frame 22, one end of the corner turner 72 is directly or indirectly connected to the control handle 3, and the other end is connected to the corner turner slider bar 73. The corner turner slider bar 73 can be directly or indirectly connected to multiple clamping columns 21, and the multiple clamping columns 21 are respectively connected to the detachable structure of the connecting piece, and the detachable structure is an "L"-shaped notch. A flange is provided at the end of the clamping column 21, which can prevent the clamping column 21 from detaching from the detachable structure in the longitudinal direction. Such a design has higher safety.

[0056] Specifically, the telescopic end of the control handle 3 is connected to one end of the corner turner 72 through the limit connecting rod 71 and the corner turner slider bar 73 in sequence, and the other end of the corner turner 72 is connected through the corner turner slider bar 73, the limit bar 74, another corner turner slider bar 73 and one end of another corner turner 72 in sequence, and the other end of the corner turner 72 is connected to the corner turner slider bar 73. The corner turner slider bars 73 on the left and right sides of the window sash 2 are directly or indirectly provided with lock columns 52, and the window frame 1 is provided with lock points 51 at corresponding positions. In this embodiment, the corner slider bars on the upper and lower sides of the window sash 2 are connected with corner locking sliders 76, and the corner locking slider 76 is provided with a clamping column 21.

[0057] By switching the gear of the control handle 3, the telescopic end of the control handle 3 is extended or retracted, and the locking column 52 and the clamping column 21 are driven to move through the transmission member, so that the window sash 2 has three working states: lockable, one-side open and the other open.

[0058] [Limit lock box 6]

[0059] Reference Figure 6 and Figure 7 As shown, in some embodiments, a limit lock box 6 is further included, wherein the limit lock box 6 includes a shell 61, and limit members 62 relatively arranged at both ends of the shell 61, wherein the limit members 62 are movably connected to the shell 61, and the limit members 62 include a locking portion 63 and a pushed portion 64; the sliding support 4 includes a left-opening sliding support 4 and a right-opening sliding support 4, wherein the sliding support 4 includes a window sill rod 42 connected to the window frame 1, and a supporting rod 41 connected to the window sash 2, wherein a hinge connection is connected between the supporting rod 41 and the window sill rod 42, and the detachable structure is arranged on the supporting rod 41, and when the sliding support 4 is in the open state, a limit portion 411 is provided at the end of the supporting rod 41 that is farther away from the window sill rod 42, and the limit portion 411 matches the locking portion 63, and when the locking portion 63 is locked with the limit portion 411 on one side, the sliding support 4 can be limited from opening.

[0060] Specifically, the limit lock box 6 includes a shell 61, and a limit member 62 disposed at both ends of the shell 61, the limit member 62 is movably connected to the shell 61, and the limit member 62 includes a locking portion 63 and a pushed portion 64, wherein when the pushed portion 64 is acted upon by an external force, the locking portion 63 corresponding to the pushed portion 64 can move toward the shell 61 or outside the shell 61, and when the external force is removed, the locking portion 63 can be reset. In this embodiment, the limit member 62 is slidably connected to the shell 61, the locking portion 63 is used to engage with the limiting portion 411 of the sliding support 4 to limit the sliding support 4 from being opened, and the pushed portion 64 is used to receive an external force to engage or disengage the locking portion 63 with the limiting portion 411 to limit the movement of the sliding support 4. The external force can come from a limit bar 74, and the limit bar 74 is provided with a force applying member 741, and the force applying member 741 pushes the pushed portion 64 to engage or disengage the locking portion 63 with the limiting portion 411. Preferably, the limit lock box 6 is normally in engagement with the limiting portion 411 to limit the movement of the sliding support 4 .

[0061] The limit lock box 6 of this embodiment has a simple structure, a low error rate and high reliability. Slide supports 4 are correspondingly arranged on both sides of the limit lock box 6. Only one side of the slide support 4 and the limit lock box 6 can be changed to limit the state, and the limit states of both sides and the slide support 4 cannot be changed at the same time.

[0062] It can be understood that the limit lock box 6 is not only used to limit the sliding support 4, but also can be used to limit other movable parts.

[0063] In some embodiments, there are two limit members 62, which are respectively arranged at the two ends of the shell 61, and the pushed surfaces 65 of the pushed portion 64 are arranged opposite to each other. When an external force acts on the pushed surface 65, the locking portion 63 corresponding to the pushed surface 65 moves toward the direction of the shell 61. Specifically, the pushed portion 64 is provided with a pushed surface 65, and the pushed surfaces 65 of the two pushed portions 64 are arranged opposite to each other. The force applying member 741 of the limit bar 74 is arranged between the two pushed surfaces 65. When the force applying member 741 moves, it can only push one of the pushed surfaces 65. In this embodiment, when the pushed portion 64 is not pushed, the corresponding locking portion 63 engages with the limit portion of the sliding support 4 to limit the sliding support 4 from being opened. Such a design of this embodiment can prevent the sliding supports 4 on both sides from being opened at the same time.

[0064] In some embodiments, a force-applying member 741 for pushing the pushed surface 65 is further included. The force-applying member 741 can move between the two pushed surfaces 65 and can push the pushed surface 65. The space between the two pushed surfaces 65 is an extended travel space 66. When the force-applying member 741 is in the middle position of the extended travel space 66, it does not contact the pushed surfaces 65 on both sides. Specifically, the distance between the two pushed surfaces 65 is greater than the width of the force-applying member 741, so that when the force-applying member 741 is in the middle position, it does not contact the pushed surfaces 65 on both sides. The space between the two sides is the extended travel space 66. The stroke of the force-applying member 741 is greater than the stroke of the limiting member 62, that is, the force-applying member 741 cannot push the limiting member 62 when it starts to move. The force-applying member 741 needs to move a certain stroke before it can push the limiting member 62 to move. Such a design can prevent the limiting member 62 from being locked or disengaged from the sliding support 4 in advance when the control handle 3 gear is not fully switched.

[0065] In some embodiments, the two limiting members 62 are staggered, and the locking parts 63, the pushed parts 64 and the force applying member 741 at both ends are located on a straight line. Specifically, the locking parts 63 at both ends have corners and protrude out of the housing 61, and the limiting members 62 are staggered, the pushed surfaces 65 at both ends are arranged oppositely, the force applying member 741 is arranged between the two pushed surfaces 65, and the pushed surfaces 65, the locking parts 63 and the force applying member 741 move on the same straight line. With such a design, the force is more reasonable and not easy to slip.

[0066] In some embodiments, a limiting structure is provided between the locking portion 63 and the pushed portion 64, and when the pushed portion 64 of one of the limiting members 62 is pushed, the limiting structure can limit the movement of the other limiting member 62. Specifically, the pushed portion 64 of one limiting member 62 and the moving path of the locking portion 63 of the other limiting member 62 partially overlap, and when the pushed portion 64 is pushed, the locking portion 63 of the other limiting member 62 can be blocked from moving.

[0067] In some embodiments, the limiting structure includes a limiting surface 1 67 provided on the pushed portion 64, and a limiting surface 2 68 provided on the locking portion 63, and the movement tracks of the limiting surface 1 67 and the limiting surface 2 68 have overlapping parts. Specifically, the limiting surface 1 67 and the limiting surface 2 68 are arranged opposite to each other, and when viewed in the lateral direction, the limiting surface 1 67 and the limiting surface 2 68 have overlapping projection areas. This embodiment has higher safety, can only control the locking portion 63 from one side, and can prevent the locking portion 63 from failing to reset.

[0068] In some embodiments, the housing 61 includes a bottom housing and an upper cover covering the bottom housing, the bottom housing is slidably connected with the stopper 62, and an elastic member 69 is provided between the stopper 62 and the housing 61. The elastic member 69 is used to reset the stopper 62, and the elastic member 69 may be a spring, a compression spring, a spring sheet, or a structure with elastic force.

[0069] In some embodiments, the housing 61 is provided with a mounting and fixing structure. In this embodiment, the mounting and fixing structure is a fastener hole 691, through which the screw is fixed to the sash frame 22.

[0070] In some embodiments, an anti-mistake switch 8 is also included, and the anti-mistake switch 8 includes an anti-mistake base 81 fixedly set on the window sash 2, and a limit block 82 movably connected to the anti-mistake base 81, and the limit block 82 has a first position that allows the transmission member to transmit, and a second position that blocks the transmission member from transmitting. When the window sash 2 is closed with the window frame 1, the limit block 82 is in the first position; when the window sash 2 is opened, the limit block 82 is in the second position.

[0071] Example 2

[0072] [Limiting structure]

[0073] Reference Figure 8As shown, the main difference between Example 2 and Example 1 is that it also has a limiting structure, which includes: a corner turner 72, which includes a corner turner body in an "L" shape, and a connecting slider 1 and a connecting slider 2 movably connected to the two ends of the corner turner body, and the connecting slider 1 and the connecting slider 2 can be extended or retracted in the corner turner body; a sliding support 4, which is provided with a detachable structure, and is directly or indirectly connected to the connecting slider 2 through the detachable structure; a locking member 1 721, which is directly or indirectly fixedly connected to the connecting slider 1 and can move with the connecting slider 1; and a locking member 2 722, which is directly or indirectly fixedly connected to the sliding support 4; wherein, when the connecting slider 1 moves toward the corner turner 72, the locking member 1 721 is locked with the locking member 2 722, and the sliding support 4 is locked and connected with the connecting slider 2; when the connecting slider 2 moves toward the outside of the corner turner 72, the locking member 1 721 and the locking member 2 722 are unlocked, and the sliding support 4 can be detached from the connecting slider 2. When the lock member 1 721 and the lock member 2 722 are in the locked state, the locking column 21 can be restricted from being separated from the sliding support 4 , and the gear position of the control handle 3 needs to be switched to separate the lock member 1 721 and the lock member 2 722 .

[0074] When the lock element 1 721 and the lock element 2 722 are in the locked state, they can effectively limit the disengagement of the sliding support 4 and the card column 21, thereby preventing the window from opening unexpectedly, improving the safety of the system, and the lock element 1 721 and the lock element 2 722 can only be disengaged by switching the gear position of the control handle 3, further enhancing the overall safety.

[0075] In some embodiments, the detachable structure is an "L"-shaped notch, and the connecting slider 2 is directly or indirectly provided with a clamping column 21 matching the notch, and the clamping column 21 can be locked with or detached from the notch. An anti-detachment head is provided at the end of the clamping column 21, and the anti-detachment head can be a flange. In the longitudinal direction, the anti-detachment head can prevent the clamping column 21 from detaching from the notch. The stability of the connection between the clamping column 21 and the sliding support 4 is enhanced.

[0076] In some embodiments, the sliding support 4 includes a window edge rod 42 connected to the window frame 1, and a support rod 41 connected to the window sash 2, a hinge connection is connected between the support rod 41 and the window edge rod 42, and the detachable structure is arranged on the support rod 41.

[0077] In some embodiments, the lock 1 721 is arranged on the outer side of the corner turner body near the corner, and the lock 2 722 is arranged at the end of the slide support 4. Specifically, the lock 2 722 is arranged at the end of the slide support 4 near the corner of the corner turner 72. The lock 2 722 is a lock pin column, and the lock 1 721 is a lock pin sleeve, and the lock pin sleeve has a sleeve hole arranged toward the lock pin column. Such a design structure is simple and ingenious, and can make the lock 1 721 and the lock 2 722 stably combined.

[0078] In some embodiments, the cross section of the locking pin sleeve gradually decreases as the distance from the pin is gradually reduced. Specifically, along the longitudinal direction, the locking pin sleeve gradually becomes smaller from the bottom to the top. Such a design can save the material of the locking pin sleeve and has better economic benefits.

[0079] In some embodiments, the end of the locking pin has a guide structure 723. The guide structure 723 can be a chamfer or a rounded corner set at the end edge of the locking pin, and the locking pin can also be set as a cylinder that gradually becomes smaller from bottom to top in the longitudinal direction. The guide structure 723 can make the locking pin sleeve and the locking pin fit smoothly.

[0080] Example 3

[0081] Reference Fig. 9 As shown, the main difference between Example 3 and other examples is that the connecting member is a hinge, and the hinge is arranged on opposite sides of the window sash 2. The hinge includes a half hinge 1 91 arranged on the window sash 2, and a half hinge 2 92 arranged on the window frame 1. The half hinge 1 91 and the half hinge 2 92 are relatively provided with an engageable hinge structure, and the handle can control the half hinge 1 91 and the half hinge 2 92 to engage or separate. One of the half hinge 1 91 and the half hinge 2 92 has a cylindrical pin, and the other of the half hinge 1 91 and the half hinge 2 92 has a sleeve hole. When the half hinge 1 91 and the half hinge 2 92 are engaged, the cylindrical pin is inserted into the sleeve hole, and the half hinge 1 91 and the half hinge 2 92 are hinged. The half hinge 1 91 is connected to the transmission member of the sash frame 22, and the half hinge 1 91 and the half hinge 2 92 can be controlled to engage or separate by controlling the handle 3 to switch gears.

[0082] It can be understood that the round pin is movably arranged on the half hinge 1 91 or the half hinge 2 92 , and the control handle 3 can control the round pin to extend or retract in the half hinge 1 91 or the half hinge 2 92 , thereby realizing the engagement or separation of the half hinge 1 91 and the half hinge 2 92 .

[0083] The hinges can be divided into left and right hinges. When the control handle 3 is in the locking position, the left and right hinges can be engaged or disengaged; when the control handle 3 is switched to the position for opening one side, the left hinge is in the engaged state and the right hinge is in the disengaged state, and the window sash 2 can be opened on one side; when the window sash 2 is closed, when the control handle 3 is switched to the position for opening the other side, the left hinge is in the disengaged state and the right hinge is in the engaged state, and the window sash 2 can be opened on the other side.

[0084] The present invention realizes that the window sash 2 can be opened on two opposite sides through a control handle 3. Specifically, the connecting member is not limited to the sliding support 4, hinge or hinge, but can also be other types of connecting members, as long as the window sash 2 or window frame 1 can be separated from the connecting member by the operation of the control handle 3. Therefore, the present invention is not limited to realizing opening on the opposite side, but can also realize opening on the adjacent two sides. In addition, the control handle 3 with more gears can be selected to cooperate with the connecting members on multiple sides to realize the function of opening on multiple sides.

[0085] The invention can be used together with a screen and a window support.

[0086] It should be noted that, in order to facilitate the clear description of the invention concept, the present invention is described by taking a window as an example, but in fact, the present invention is also applicable to the field of door technology, that is, to achieve multi-side opening of a door through a similar control mechanism.

[0087] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
