Description

Projectile launcher

[0001] The present invention relates to a projectile throwing device, and more particularly, to a projectile throwing device capable of providing sufficient force to a projectile based on elasticity, thereby enabling a long launch distance while allowing selection of launch timing and accurately hitting a launch target point.

[0002] Throwing devices that throw projectiles, such as flashbangs or tear gas grenades, are used in many fields.

[0003] In general, conventional throwing devices often use centrifugal force to throw a projectile. In this case, the projectile may be attached to an end of a simply rotating support, and then the support may be rotated to separate the projectile from the support by centrifugal force.

[0004] In other words, conventional projectile throwing devices threw projectiles while rotating the projectile within the same radius.

[0005] However, conventional projectiles utilize centrifugal force, making it difficult to control the launch distance of the projectile. Furthermore, even when projectiles need to be launched far, the power required cannot be sufficient, limiting launch distance. Furthermore, because the projectile is launched in a curved path by the projectile, it is difficult to accurately target the target.

[0006] Accordingly, there is a need to develop a new configuration of a projectile that can provide sufficient power to the projectile to enable a long launch distance while also accurately hitting the launch target.

[0007] An embodiment of the present invention provides a projectile throwing device that can provide sufficient force to a projectile based on elasticity, thereby enabling a long launch distance while allowing selection of launch timing and accurately hitting a launch target point.

[0017] According to one aspect, the engaging member may include a contact portion that contacts the outer edge of the engaging portion when the linear moving portion moves forward; and an engaging portion that has a cross-section in the shape of a D-shape that is open toward the outer edge of the engaging portion, and that rotates when the contact portion is contacted by the engaging portion to engage the engaging portion.

[0018] According to one side, the engaging member may further include a engaging release protrusion that is provided at the rear end of the engaging portion and, when the linear moving portion moves backward by the driving unit, comes into contact with the engaging release portion and is gathered inwardly of the engaging release portion to release the engaging portion from the engaged portion.

[0028]

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] FIG. 1 is a projection drawing partially showing the internal configuration of a projectile throwing device according to one embodiment of the present invention.

[0031] As illustrated in FIG. 1, a projectile throwing device (100) according to one embodiment of the present invention is a device that uses elastic force to throw an object (121) such as a ball, a projectile such as a tear gas grenade or a flash grenade, etc., to a desired location at a desired launch time, and comprises a device housing (110) that forms a frame of the device, a projectile holder (120) that is provided at the front end of the device housing (110) and launches a projectile (120) accommodated in an internal space by the elastic force of an elastic member (115), a linear moving part (130) that is provided at the front end with a catch (140) that catches the rear end of the projectile holder (120) and pulls the projectile holder (120) while moving linearly within the device housing (110) by a driving force provided from a driving part (150), and a catch (140) of the linear moving part (130) that catches and pulls the rear end of the projectile holder (120) when the projectile is pulled. It may include a release unit (160) that provides propulsion to the projectile holder (120) by releasing the locking unit (140) on the holder (120) so that the projectile (120) in the projectile holder (120) is launched, and a control unit (not shown) that wirelessly controls the driving of the driving unit (150).

[0032] By this configuration, sufficient force can be provided to the projectile (120) based on elasticity, so that the launch distance can be extended while also accurately hitting the launch target point.

[0033] When explaining each configuration, first, the device housing (110) of the present embodiment forms the entire frame of the device as shown in FIG. 1, and may have a columnar shape, for example, a cylindrical shape, with one side open and the other side blocked.

[0034] An elastic member (115) that generates elastic force in one direction may be provided in the internal space of the device housing (110). That is, one end of the spring-type elastic member (115) may be provided to be supported by the other end that is blocked in the internal space of the device housing (110), and a projectile holder (120) that accommodates a projectile (120) so that it can be launched may be provided to be supported by the other end of the elastic member (115), i.e., the tip end.

[0035] Referring to FIG. 1, the projectile holder (120) is provided so as to be able to move forward and backward in the internal space of the device housing (110). As will be described later, the projectile holder (120) moves backward and then moves forward by receiving propulsion from an elastic member (115) supporting the projectile holder (120), thereby allowing the projectile (120) accommodated therein to be launched, depending on the interaction with the linear moving part (130).

[0036] As illustrated in FIG. 1, the outer shape of the projectile holder (120) and the shape of the inner space of the device housing (110) correspond to each other so that the projectile holder (120) can be linearly moved while being guided along the inner wall of the device housing (110).

[0037] The front end of the device housing (110) may be provided with a stopper (113) to prevent the projectile holder (120) from coming off. As a result, even if the projectile holder (120) moves forward by the elastic member (115) as described above, the move can be stopped by the stopper (113), and at this time, the projectile (121) in the projectile holder (120) can be launched by inertia.

[0038] Meanwhile, the linear moving part (130) of the present embodiment, as illustrated in FIG. 1, is provided with a catch (140) at the front end that catches a catch (125) provided at the rear end of the projectile holder (120), and can pull the projectile holder (120) while moving linearly within the device housing (110) by a driving force provided from a driving part (150) to be described later.

[0039] As illustrated in Fig. 1, this linear moving part (130) may have a hollow shape with an empty interior and may have screw threads (131) formed on the inner surface of the rear end. Due to this structure, the rotational motion of one component of the driving part (150) may be converted into linear movement of the linear moving part (130).

[0040] To this end, the configuration of the driving unit (150) will first be described. As shown in FIG. 1, the driving unit (150) of the present embodiment may include a driving motor (151), a lead screw (155) coupled to the rear end of the linear moving unit (130) to linearly move the linear moving unit (130) by rotating in place, and a transmission member (not shown) that transmits the axial rotation of the driving motor (151) to the lead screw (155).

[0041] The drive motor (151) may be provided as a DC motor (151). The transmission member may have a timing belt and pulley structure. Although not illustrated in detail, the transmission member may include a first pulley coupled to the shaft of the drive motor (151), a second pulley coupled to the rear end of the lead screw (155), and a timing belt coupled to the first pulley and the second pulley to transmit the rotation of the first pulley by the drive motor (151) to the second pulley.

[0042] The lead screw (155), as illustrated in FIG. 1, is provided to penetrate the rear wall of the device housing (110) and can rotate by the rotation of the driving motor (151). A screw thread (156) is provided on the outer surface of the lead screw (155), and the lead screw (155) can be inserted into the rear end of the linear movement unit (130) and screw-coupled. That is, the screw thread (131) formed on the inner surface of the linear movement unit (130) and the screw thread (156) formed on the outer surface of the lead screw (155) can be screw-coupled, and when the lead screw (155) is rotated through this, the linear movement unit (130) can be linearly moved.

[0043] The linear moving part (130) has a structure that prevents rotation, so that the linear moving part (130) can move forward or backward when the lead screw (155) rotates.

[0044] For example, when the lead screw (155) is rotated in one direction, the linear moving part (130) can be linearly moved forward, and when the lead screw (155) is rotated in the opposite direction, the linear moving part (130) can be linearly moved backward.

[0045] Meanwhile, referring to FIG. 1, the throwing device (100) of the present embodiment may further include a guide part (170) for guiding the linear movement of the linear moving part (130).

[0046] The guide part (170) of the present embodiment is provided to surround the linear moving part (130) within the device housing (110), so as to guide the linear movement of the linear moving part (130) and prevent the linear moving part (130) from rotating when moving linearly.

[0047] For example, although not shown, the outer surface of the linear moving part (130) may be provided with a guide protrusion for guidance, and the inner surface of the guide part (170) may be provided with a guide groove for guiding the linear movement of the guide protrusion, so that the linear moving part (130) can move linearly within the guide part (170) without rotating.

[0048] The tip of the guide portion (170) may be provided with a release portion (160) for releasing the release portion (140) from the projectile holder (120), as illustrated in FIG. 1. The release portion (160) releases the release portion (140) from the release portion (125) to be described later, which will be described later.

[0049] Although not shown, it is to be understood that the guide portion (170) may be positionally adjusted in the longitudinal direction within the device housing (110). When the projectile holder (120) is pulled by the catch portion (140) provided in the linear moving portion (130), for example, if the position of the guide portion (170) is positioned forward of the position in FIG. 1, the degree of compression of the elastic member (115) can be reduced, thereby making the launch distance of the projectile (120) smaller than in the case of FIG. 1.

[0050] That is, the degree of elasticity of the elastic member (115) can be adjusted by adjusting the position of the guide part (170), thereby controlling the launch distance of the projectile (120).

[0051] Meanwhile, a catch (140) that catches or is released from a catch (125) provided at the rear end of the projectile holder (120) is provided at the front end of the linear moving part (130), thereby enabling the projectile (120) of the projectile holder (120) to be launched.

[0052] Referring to Fig. 1, a circular plate-shaped engaging portion (125) may be provided on the bottom surface of the projectile holder (120). In addition, a engaging portion (140) may be provided on the tip of the aforementioned linear moving portion (130), so that engaging and releasing of the engaging portion (140) with respect to the engaging portion (125) can be selectively performed.

[0053] The engaging member (140) of the present embodiment may include, as shown in FIG. 1, a fixing member (141) that is fixed to the front end of the linear moving member (130) and has a shape symmetrical with respect to the fixing portion with respect to the linear moving member (130), and a fixing member (145) that is coupled to both sides of the fixing member (141) and is provided so as to be rotatable around the coupling portion, and that, when moving toward the engaging member (125), is bent by contact with the engaging member (125) to engage the engaging member (125).

[0054] In other words, when the linear moving part (130) moves linearly, the engaging member (145) of the engaging part (140) comes into contact with the engaging part (125) and is immediately caught.

[0055] Referring to FIG. 1, the engaging member (145) of the present embodiment may include a contact portion (146) that first contacts the outer edge of the engaging portion (125) when the linear moving portion (130) moves forward, and an engaging portion (147) that has a cross-section in the shape of a diguttite that is open toward the outer edge of the engaging portion (125) and rotates when the contact portion (146) is contacted by the engaging portion (125) to engage the engaging portion (125).

[0056] In addition, the engaging member (145) of the present embodiment may further include a engaging release protrusion (148) provided at the rear end of the engaging portion (147) for mutual operation with the engaging release portion (160) described above, as illustrated in FIG. 1.

[0057] When the linear moving part (130) moves backward while the engaging part (140) engages the engaging part (125), the engaging release projection (148) comes into contact with the engaging release part (160) and is gathered and moved into the inside of the engaging release part (160).

[0058] That is, as the release protrusion (148) enters the inside of the release portion (160), the engaging portion (147) formed integrally with it rotates outward, thereby releasing the engaging portion (140) from the engaging portion (125), thereby allowing the projectile holder (120) to advance by the elastic force of the elastic member (115) supporting it. That is, the projectile (120) can be launched by the advancement of the projectile holder (120).

[0059] In addition, the throwing device (100) of the present embodiment may further include a control unit that wirelessly controls the driving of the driving unit (150), and the linear movement of the linear moving unit (130) through the driving unit (150) can be controlled by the control of the control unit, and through this, the timing of launching the projectile (120) accommodated in the projectile holder (120) can be determined.

[0060] Meanwhile, the operation of the projectile throwing device (100) of the above-described configuration will be described below with reference to FIGS. 2 and 4.

[0061] FIG. 2 is a drawing showing the initial state and the stuck state of the throwing device of FIG. 1, FIG. 3 is a drawing showing the loaded state of the throwing device of FIG. 1, and FIG. 4 is a drawing showing the firing state of the throwing device of FIG. 1.

[0062] First, as illustrated in the upper drawing of FIG. 2, the projectile throwing device (100) of the present embodiment can have an initial state. That is, the projectile holder (120) is positioned at the front end of the device housing (110), and the engaging portion (140) can be maintained in a state of being spaced apart from it. The throwing device (100) in normal times can maintain this state.

[0063] In this state, when a projectile (120) is to be thrown, as shown in the lower drawing of Fig. 2, the linear moving part (130) having the engaging part (140) provided at the tip can be linearly moved toward the projectile holder (120) so that the engaging part (140) of the linear moving part (130) is engaged with the engaging part (125) of the projectile holder (120). At this time, when the driving part (150) is driven, the linear moving part (130) can move linearly by the rotational motion of the lead screw (155), and through this, the engaging part (140) can be engaged with the engaging part (125).

[0064] Thereafter, as shown in FIG. 3, when the driving unit (150) is driven to linearly move the linear moving unit (130) backward, the projectile holder (120) can be pulled toward the inside of the device housing (110) due to the engagement of the engaging unit (125) and engaging unit (140), and at this time, the elastic member (115) can also be compressed.

[0065] And at this time, a projectile (120) such as a ball can be accommodated in the accommodation space of the projectile holder (120).

[0066] In the state of FIG. 3, when the rear end of the engaging portion (140) is pulled until it is drawn into the engaging release portion (160) as shown in the upper drawing of FIG. 4, the engaging portion (140) of the engaging portion (125) of the projectile holder (120) is released, and the projectile holder (120) can be forcefully advanced forward as shown in the lower drawing of FIG. 4, and when the projectile holder (120) collides with the stopper (113) provided at the front end of the device housing (110) and stops, an inertial force is applied to the projectile (120) so that the projectile (120) can be launched to a desired point.

[0067] Meanwhile, although not shown, the projectile throwing device (100) of the present embodiment may be mounted on various devices or locations, for example, it may be mounted on the body of a multi-legged robot such as a quadruped robot. The throwing device (100) may be mounted on the body of the multi-legged robot in a manner that allows for angle and direction adjustments, and the throwing device (100) may be controlled by an external control unit to launch the projectile (120) at a desired time and location.

[0068] In this way, according to an embodiment of the present invention, sufficient force can be provided to the projectile (120) based on elasticity, so that the launch distance can be extended while the launch timing can be selected, and the launch target point can also be accurately hit.

[0069]

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the claims set forth below, but also by equivalents thereof.

[0071] Although the present invention has been described with reference to limited embodiments and drawings, it is not limited to the above-described embodiments. Those skilled in the art will appreciate that various modifications and variations are possible based on this disclosure. Therefore, the scope of the present invention should be understood solely by the scope of the claims set forth below, and all equivalent or equivalent modifications thereof are deemed to fall within the scope of the present invention.
