    Sunshade
    The invention relates to an improved awning.
    A sunshade is a utensil for outdoor activities. Since the required screen area is large, it must be possible to open and close the screen without great physical effort and the fixation must be simple. The current screen towers consist of at least two parts and a hinge, such as the published system of a Chinese utility model with application number 93218449.9 with description "a type of awning". The structure of this consists of an upper mast with two mast hinges. The upper mast is surrounded by a drum and on the outside of the drum hinged fencing posts are evenly distributed. An upper drum is attached to the upper end of the mast and an extendable inner mast is connected to the outside of the upper drum. The other part of the extendable inner mast is separated from the inner screen post pivot of the extendable outer mast. The extendable outer mast is separated with the other end of the inner screen post from the outer screen post and forms the screen carrier. The screen carrier is covered by the screen surface. A plug is attached under the mast. The plug plugs into a socket that can be used to determine the position of the screen.
    The screen mast constructions which are in the current state of the art described above exhibit certain defects which, because of the uneven pulling force applied from outside, can very quickly lead to damage to or breakage of the screen mast. Moreover, the stability of the screen mast in the construction described above is not very high, the service life is short and the structure is moreover relatively complex. Moreover, the safety of the locking system arranged under the screen mast is insufficient, so that an improved awning must be offered, the interconnected inner and outer tubes of which allow the opening and closing of the screen and at the lower end of the screen mast a correct locking system with increased safety is used.
    The technical problems to be solved by this invention relate to the current state of the art described above, and the invention offers a simple sunshade system with stable connections, a pleasant tube system from inner and outer tubes that is easy to open.
    To this end, the invention provides: a sunshade consisting of an upper screen drum, lower screen drum, long screen style and short screen style. The long screen posts are pivotally connected to the upper screen post with hinges, the end of the short screen post is hinged to the lower screen drum, and the other end of the short screen post is pivotally connected to the upper end of the long screen posts and forms the screen frame. The characteristics of this are: The described upper screen drum and the lower screen drum are connected to each other via an inner and outer tube. Several concave surfaces are formed on the described inner tube. Accordingly, the outer tubes opposite the inner tube can be installed sliding up and down in the concave surfaces. The upper screen drum is attached to the upper ends of the outer tubes. The lower screen drum can be dismantled and packaged on the outer tubes and on the inner tube and, moreover, fixed in the upper part of the inner tube with a fixation piece. A fixation sleeve is provided in the lower part of the outer tubes which is used to determine the position of the outer tubes. Moreover, a locking system is provided at the location of the position of the outer tubes.
    As an improvement, as described above, some concave surfaces were evenly distributed around.
    As an improvement, three concave surfaces were formed on the inner tube described above. Accordingly, the three outer tubes are installed in the concave surfaces of the inner tube. The shape of the outer tubes was adapted to the concave surfaces of the inner tube.
    As an improvement, there are circular arc surfaces that are uniformly adapted to the outer tubes on the outside of the fixation sleeve. In the lower part of the circular arc surfaces there are convex position-determining platforms formed for receiving the outer tubes. The outer tubes are attached to the convex position-determining platforms by means of connecting screws. On the underside of the convex postion determination platforms protruding downward projecting pins are provided on the fixation sleeves. Correspondingly, position-determining drill holes adapted at the lower end of the inner tube are provided for receiving the position-determining pins.
    As an improvement, the locking system described above consists of: It comprises a handle, a fixation base, a fixation hook and a handle. An opening for the hand was formed on the inside of the handle. Round drill holes are provided at the upper and lower ends of the handle. Corresponding thereto, adapted threaded holes are provided opposite the outer tube. The handle is fixed to the outer tubes by means of screws through round drill holes on the handle and adapted threaded holes. The fixation base is welded to the inner tube under the handle. A fixation borehole is formed on the fixation base. Safety drill holes are provided on the underside of the fixation drill holes. Correspondingly, handle boreholes and keyholes corresponding to the fixation and security boreholes are provided at the upper end of the handle. The fixation base is rotatably connected to the handle by means of fixation and handle drill holes with connecting pieces with hinges. The lower end of the fixation hook is rotatably connected to the handle with fixing screws and nuts with hinges.
    As an improvement, convex position determining surfaces are formed on both sides of the upper end of the fixation hook. Accordingly, position-determining nuts were formed in the lower part of the handle which are used to clamp the concave position-determining surfaces.
    Finally, connecting drill holes are provided in the lower part of the described disassembled lower screen drum. Threaded drill holes are provided at the corresponding position of the inner tube to connect the lower screen drum and the inner tube with the aid of fixing screws.
    In comparison with the current state of the art, this invention has the following advantages: By using an inner tube and suitable sliding outer tubes, this system can be used in two ways. Moreover, a fixation sleeve is provided in the lower part of the outer housing to connect the three upper tube parts, whereby the connections in this product become even more stable and the service life is extended. In addition, the construction of a locking system is sophisticated and the use of the reaction forces existing between the individual components makes it possible to open and close the screen so that not only the closing function is excellent, but also the safety boreholes on the fixation base perform the safety function. This prevents unauthorized closing of the screen and increases safety. The connection type of the lower screen drum is removable and can be packaged small.

    The images show a sunshade according to the invention, consisting of an upper screen drum (1), lower screen drum (3), long screen style (2) and short screen style (4). The long screen posts (2) are evenly connected to the upper screen post (1) with hinges. One end of the short screen post (4) is hinged to the lower screen drum (3). The other end of the short screen post (4) is rotatably connected to the upper end of the long screen post (2) and forms the screen frame. Upper (1) and lower (3) screen posts are connected to each other via an inner tube (5) and an outer tube (6). Three evenly distributed concave surfaces were formed on the inner tube. Accordingly, three country houses (6) were installed in the concave surfaces. The shape of the outer housings (6) was adapted to the concave surfaces of the inner housings (5). The upper screen drum (1) is attached to the upper ends of the three outer casings (6). The upper screen drum (1) and the outer tubes (6) can slide up and down on the inner tube (5). The lower screen drum (3) can be packaged and disassembled on the outer tubes (6) and on the inner tube (5). Three connecting drill holes (3.1) are provided in the lower part of the lower screen drum (3). Three threaded drill holes are provided at the corresponding position of the inner tube (5) to connect the lower screen drum (3) and the inner tube (5) to each other with the aid of fixing screws (7). In the lower part of the outer tubes (6) a fixation sleeve (8) is used for determining the position of the outer tubes (6). On the outside of the fixation sleeve (8) there are also three circular arc surfaces (8.1) formed for receiving and fixing the outer tubes (6). In the lower part of the circular arc surfaces (8.1), convex position determining platforms (9) are formed for receiving the outer tubes (6). On the bottom of the convex position-determining platforms, downwardly projecting position pins (10) are arranged on the fixation sleeve (8). Accordingly, at the lower end of the inner tube (5), position determination drill holes (11) adapted to the position determining pins are provided. The fixation sleeve (8) with the outer tubes (6) is thereby fixedly connected with the small drill holes (14) to the outer tubes (6) by means of fixing screws (12) from the series through drill holes (13) arranged on the position-determining platform (9). . Moreover, a locking system is provided on one side in the lower part of the outer tube (6). The locking system consists of a handle (15), a fixation base (16), a fixation hook (17) and a handle (18). The handle (15) is fastened to the outer tubes (6) with the aid of 2 screws (19) which are secured to the handle through round drill holes (20) and two adapted threaded drill holes (21) in the lower part of the outer tubes (6). The edge of the fixation base is welded to the lower part of the inner tube (5). The connecting piece and connecting screws (22) are rotatably connected through fixation drill holes (24) provided on the fixing base with screw nuts located on the upper end of the handle (18). At the same time, security boreholes (25) are provided on the underside of the fixation holes (23) provided on the fixation base (16). Corresponding to this, on the underside of the rotary drill holes (24) placed on the handle (18), also key holes (26) are provided. Security boreholes (25) and keyholes (26) can provide the screen with a fully open position a safety lock to ensure that in the event of operation by specialists, unauthorized persons cannot close the screen, thus increasing the theft protection of the screen. Convex position determination surfaces (27) were formed on both sides of the upper end of the fixing pins. Accordingly, position-determining nuts (28) were formed in the lower part of the handle (15) for clamping the concave position-determining surfaces. The lower end of the fastening pins (17) is connected to fastening screws (29) through the round connecting boreholes (30) and the connecting boreholes (31) and is hinged to the middle part of the handle (18) with screw nuts .
    In use, the handle (15) is pushed from top to bottom and you can open and close the screen. When the screen is in the closed state, the handle (15) is pulled down, causing the screen to open slowly. When the handle (15) is pulled into the lower part of the inner tube and the handle (18) is turned upwards with the other hand, the convex position determining surface (27) of the fastening pin (17) in the lower part of the position determining nut is thereby clamped. When the handle (18) is turned down again, the handle (15) moves down together with the fixation hook (17). If the lever (18) is rotated to a flat position, the lever (18) cannot rotate outward due to the lack of action of the external forces, since the relationship of the position of the fixation borehole (23) around connecting borehole (30) ) and a convex position determining surface changes to an inwardly directed restraining force. The handle (15) is located together with the outer tubes (6) in the lower part of the inner tube and thus completes the opening of the screen. If the screen is to be closed, the lever (18) must be turned out by hand. After the fixation hook (17) has been disengaged from the handle (17), the handle (15) only needs to be pushed upwards.
