## Background
BACKGROUND
Technical Field
The present invention relates to an interlocking telescopic rod-type defense spray apparatus, and more particularly to a defense spray apparatus in which at least two sections may be pushed to each other to spray contents of an irritant gas can, and may be positioned relative to each other to be locked into a function application having a rod-type member.
Related Art
A conventional umbrella, staff or cane is easy to carry and can be used for defense; however, in a sudden strike of an armed villain, during a fierce fight, it is still possible that the villain causes death or injuries with a strike by using a bladed weapon.
In addition, a conventional device such as a gas pistol and a self-defense spray device can be used to spurt high-pressure self-defense spray at a villain at a long distance greater than 3 meters to 4 meters before the villain approaches; however, for a function or a dosage of the device, an irritant gas or liquid can only be spurted at the face of the villain for a very few seconds to take away the vision of the villain, and if the villain closes the eyes and covers the mouth and nose and keeps slashing wildly with a weapon, the gas pistol and the self-defense spray are basically useless to stop the villain. Moreover, for the purpose of portability, a self-defense spray can is generally small and has a small volume, and a dosage of an irritant gas in the self-defense spray can can support only a limited quantity of times of spurting. When the self-defense spray can is emptied after several times of spurting, if a danger still exists, an article such as an umbrella needs to be used for defense to resist an attack.
SUMMARY
An objective of the present invention is to provide an interlocking telescopic rod-type defense spray apparatus. In the interlocking telescopic rod-type defense spray apparatus, two sectioned tube pieces and a telescopic-rod packing device between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a push spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces.
To achieve the foregoing objective, the present invention provides an interlocking telescopic rod-type defense spray apparatus, used to unlock telescopic rods to spray contents of an irritant gas can disposed inside the apparatus, the defense spray apparatus comprising: a first tube body, a receiving chamber being provided in an intra-tube space, having a relatively large diameter, of a head-end portion of the first tube body, an opening on an end surface of the receiving chamber being used for placing the irritant gas can, and an inner edge being provided at an opening on an end surface of a tail-end portion, to form an inwardly-shrinking hole; a cap, tightly covering the opening of the receiving chamber, the cap having a central step through hole for inserting a press-ring portion of the irritant gas can and an output tube, and a compression elastic piece being disposed between the press-ring portion and the step through hole; and a second tube body, having a rod body portion, the rod body portion comprising an upper tube, a lower tube, and a telescopic-rod packing device connecting the upper tube and the lower tube, an upper seat of the telescopic-rod packing device being fixedly connected to the upper tube, a lower seat being fixedly connected to the lower tube and having a diameter greater than that of the inwardly-shrinking hole, an eccentric shaft having two ends pivotally connected to the upper seat and the lower seat separately, and a packing ring disposed around the eccentric shaft, a top rod structure being disposed at an end, away from the upper seat, of the upper tube, and a sheath structure being fixedly disposed at an end, away from the lower seat, of the lower tube, where the second tube body is inserted from the head-end portion of the first tube body, so that the lower tube is exposed from the tail-end portion of the first tube body, the upper tube and the telescopic-rod packing device are limited inside the first tube body by using the inner edge of the inwardly-shrinking hole, the lower tube is rotated to drive a fingering plate to enable the eccentric packing ring to rotate about the eccentric shaft, so that the fingering plate pushes the packing ring and enables a thick wall of the packing ring to radially protrude from the rod body portion on a side of the eccentric shaft to tightly abut a corresponding inner wall surface of the first tube body, or the lower tube is slightly rotated in an opposite direction to drive the fingering plate to release the packing ring to enable the packing ring not to radially protrude from the rod body portion to release the corresponding inner wall surface of the first tube body, and after the telescopic-rod packing device releases the inner wall surface of the first tube body, the sheath structure of the second tube body is held and pushed toward the first tube body to enable the top rod structure to push the irritant gas can to press the press-ring portion to spray the contents.
An advantage of the present invention lies in: In the present invention, a self-defense spray can and a rod-type umbrella, staff or cane are combined, so that an irritant gas may be sprayed first and a rod-type object such as the umbrella, the staff, and the cane may then be used to resist an attack of a villain, thereby improving an effect of safety protection. In addition, during mountain climbing and walking in a mountain region or an uninhabited region, in a case of a headwind, when there is a villain, a stray dog or an animal that attacks people, if self-defense pepper spray is sprayed immediately, the spray may affect the one who sprays, so that for the rod-type structure of the cane of the present invention, the cane may be used first for defense against an attack of the villain or to drive away the animal that attacks people, and at a position of a tailwind, an irritant gas can be used to spray an irritant gas at the villain or the animal that attacks people, so that a double protection effect is achieved. Moreover, in the present invention, when a rod-type object is formed, the rod-type object itself also has a function of defense. For example, a rod piece such as a stick, an umbrella rod, and a cane is used for strikes, and an extended cloth confuses the sight of the villain or the animal that attacks people or blocks a dangerous liquid sprayed by the villains. Moreover, the present invention also has an effect of being disguised as a common rod-shaped utensil or being blended in a portable object (a utensil such as an umbrella, a cane, a short staff, a flashlight, and a golf-club) in daily lives. Therefore, an advanced apparatus that combines various defense functions is implemented.

DETAILED DESCRIPTION
The embodiments of the present invention are described below in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic views, and a basic structure of the present invention is described in a schematic manner. Therefore, only elements related to the present invention are labeled in the accompanying drawings, and the shown elements are not drawn according to quantities, shapes, sizes, proportions, and the like during implementation. Specifications and sizes during actual implementation of the elements are actually an optional design, and the layout and forms of the elements may be more complex.
First, please refer to FIG. 1, FIG. 2, and FIG. 3. An interlocking telescopic rod-type defense spray apparatus 1 in this embodiment is a two sectioned defense rod when relative axial movement of the telescopic rods is unlocked (if a tube body of the defense spray apparatus 1 is shortened, for example, an upper tube 411 is shortened or omitted, the defense spray apparatus 1 is a portable defense short stick). After the telescopic rods are unlocked, contents A3 of an irritant gas can A disposed inside the apparatus are to be sprayed. A protruding output tube A1 is provided at a top portion of the irritant gas can A, a press-ring portion A2 is provided at a periphery of the output tube A1, and the press-ring portion A2 may be subject to an external force of pressing to spray the contents A3 axially outward from the output tube A1. The irritant gas can A can be subject to high pressure, and a can body bottom portion A5 of the irritant gas can A generally has a concave form.
The defense spray apparatus 1 includes: a first tube body 10, a cap 20, a compression elastic piece 30, and a second tube body 40. The first tube body 10 has a head-end portion 11 and a tail-end portion 12, a receiving chamber 111 is provided in an intra-tube space, having a relatively large diameter, of the head-end portion 11, an opening 112 is provided on an end surface of the receiving chamber 111 and used for placing the irritant gas can A in the receiving chamber 111, and an inner edge 122 is provided at an opening on an end surface of the tail-end portion 12, to form an inwardly-shrinking hole 123. The cap 20 tightly covers the opening 112 of the receiving chamber 111 (specifically, the cap 20 covers the opening 112 of the receiving chamber 111 in many manners; in practice, an external thread may be disposed on an outer side of an end surface of the opening 112, and a corresponding inner thread is disposed on an inner edge of the cap 20, the cap 20 then covers the opening 112 in a threaded manner, or an L groove is provided on the outer side of the end surface of the opening 112, a corresponding convex end is disposed on the inner edge of the cap 20, and the cap 20 is then pressed and rotated by a rotating angle to clamp the convex end in the L groove to cover the opening 112), a recessed seat 21 is provided at a center of a surface, facing the receiving chamber 111, of the cap 20, a through hole 211 is provided at a center of the recessed seat 21, the press-ring portion A2 of the irritant gas can A corresponds to the recessed seat 21, and the output tube A1 is aligned with the through hole 211. An end of the compression elastic piece 30 is disposed on the recessed seat 21, and the other end of the compression elastic piece 30 is kept between a can body top portion A4 of the irritant gas can A (an inner diameter of the compression elastic piece 30 is greater than a diameter of the press-ring portion A2, so that a distance is stretched between the can body top portion A4 and a bottom surface of the recessed seat 21 because of an elastic force of the compression elastic piece 30, so as to avoid that when the first tube body 10 is swung upward and downward or shaken (for example, in an subsequent application to an umbrella embodiment, an action of shaking a central rod to remove rainwater, an action of poking the ground with the cane), the press-ring portion A2 pushes the bottom surface of the recessed seat 21 to spill the contents A3 of the irritant gas can A). The second tube body 40 has a rod body portion 41, the rod body portion 41 includes an upper tube 411, a lower tube 412, and a telescopic-rod packing device 413 connecting the upper tube 411 and the lower tube 412, and the telescopic-rod packing device 413 has an upper seat 4131, a lower seat 4132, an eccentric shaft 4133, and a packing ring 4134. The upper seat 4131 is fixedly connected at the upper tube 411, the lower seat 4132 is fixedly connected at the lower tube 412 and has a diameter greater than that of the inwardly-shrinking hole 123 of the tail-end portion 12 of the first tube body 10, a head end and a tail end of the eccentric shaft 4133 are pivotally connected to the upper seat 4131 and the lower seat 4132 separately, and the packing ring 4134 is disposed around the eccentric shaft 4133 and is freely rotatable about the eccentric shaft 4133. A top rod structure 4111 (which may be directly implemented by using an end surface of the upper tube 411, or disposed inside the upper tube 411) is disposed at an end, away from the upper seat 4131, of the upper tube 411, and a sheath structure 4121 is fixedly disposed at an end, away from the lower seat 4132, of the lower tube 412. The second tube body 40 is inserted from the opening 112 of the head-end portion 11 of the first tube body 10, the lower tube 412 is exposed from the tail-end portion 12 of the first tube body 10, and the upper tube 411 and the telescopic-rod packing device 413 are limited in an inner space of the first tube body 10 by using the inner edge 122 of the inwardly-shrinking hole 123.
Please continue to refer to FIG. 3 and FIG. 4, by means of the foregoing structure, when a user wants to lock the first tube body 10 and the second tube body 40 to each other to form an integrated rod body, a central axis of the second tube body 40 may be first used as a rotation axial center, and the lower tube 412 is rotated along a first direction (for example, a positive direction, a clockwise direction), so as to push the packing ring 4134 to radially deviate outward from the eccentric shaft 4133 to protrude from the rod body portion 41, so as to abut a corresponding inner wall surface 121 of the first tube body 10. In contrast, when the user wants to release a locked relationship between relative positions of the first tube body 10 and the second tube body 40, the lower tube 412 may be slightly rotated along a direction (for example, a negative direction, a counterclockwise direction) opposite to the first direction, so that the packing ring 4134 no longer deviates outward from the eccentric shaft 4133 for pushing, so as to release the packing ring 4134 to release the corresponding inner wall surface 121 of the first tube body 10.
Furthermore, a wide space 41331 is formed on a side having the longest distance from a surface of the eccentric shaft 4133 to the inner wall surface 121 of the first tube body 10, and a narrow space 41332 is formed on a side having the shortest distance from the surface of the eccentric shaft 4133 to the inner wall surface 121 of the first tube body 10. The lower seat 4132 of the telescopic-rod packing device 413 has a fingering board 41321 that rotates synchronously with rotation of the lower tube 412, the packing ring 4134 is made of a material having a large frictional coefficient, and a ring surface of the packing ring 4134 comes into contact with the inner wall surface 121 of the first tube body 10, so that when the eccentric shaft 4133 is rotated, the packing ring 4134 does not rotate accordingly, so as to achieve relative rotation. The packing ring 4134 has an eccentric hole 41343, a gap 41341 is provided between an outer diameter of the packing ring 4134 and the eccentric hole 41343, and by using the gap 41341, the eccentric hole 41343 may be disposed around the eccentric shaft 4133, so that a thick wall 41344 and a thin wall 41345 are formed from the eccentric hole 41343 to the outer diameter of the packing ring 4134, and a locking and stopping structure 41342 is formed at an end of a rotation path, corresponding to the fingering board 41321, of the packing ring 4134. When the lower tube 412 is rotated, the eccentric shaft 4133 and the fingering board 41321 rotate synchronously, so that the thick wall 41344 of the packing ring 4134 is clamped in the narrow space 41332 and an outer side of the thick wall 41344 of the packing ring 4134 protrudes outward to tightly abut the inner wall surface 121 of the first tube body 10 (in this case, the fingering board 41321 pushes the locking and stopping structure 41342), or the lower tube 412 is rotated in an opposite direction to accordingly enable the thick wall 41344 of the packing ring 4134 to be clamped in the wide space 41331 and enable the outer side of the thick wall 41344 of the packing ring 4134 to be retracted inwardly to release the inner wall surface 121 of the first tube body 10 (in this case, the fingering board 41321 leaves to release the locking and stopping structure 41342). After the telescopic-rod packing device 413 releases the inner wall surface 121 of a tube wall of the first tube body 10, the sheath structure 4121 of the second tube body 40 is held and pushed toward the first tube body 10, so that the top rod structure 4111 of the second tube body 40 is enabled to push the can body bottom portion A5 of the irritant gas can A, to press the press-ring portion A2 to spray the contents A3.
It should be noted that, in an embodiment, for example, the top rod structure 4111 in the foregoing embodiment may be directly implemented by using an end surface 4112 at an end, away from the upper seat 4131, of the upper tube 411, and subsequently the end surface 4112 of the second tube body 40 may directly push a concave position of the can body bottom portion A5 of the irritant gas can A.
In still another embodiment, a hole 41121 is provided on the end surface 4112 at an end, away from the upper seat 4131, of the upper tube 411 in the foregoing embodiment, and the top rod structure 4111 of the upper tube 411 may be disposed inside the upper tube 411 and sequentially includes a convex-type element 41111 having a top rod. 411110, a compression spring 41112, and a fixing element 41113. The fixing element 41113 is fixedly screwed on an inner wall of the upper tube 411 by using a screw 41114 to support the compression spring 41112, and the convex-type element 41111 is pushed upward by the compression spring 41112, so that the top rod 411110 protrudes from the hole 41121. A shortened travel length after the compression spring 41112 is pressed is less than a length by which the top rod 411110 protrudes from the hole 41121. The compression spring 41112 can reduce vertical shaking of the irritant gas can A in the receiving chamber 111. In other words, after position locking between the first tube body 10 and the second tube body 40 is released, when the sheath structure 4121 is held and pushed toward the first tube body 10, after the top rod 411110 of the convex-type element 41111 reaches the can body bottom portion A5 of the irritant gas can A, the convex-type element 41111 temporarily stops pushing. Instead, the compression spring 41112 absorbs a pushing force from the sheath structure 4121. After the compression spring 41112 is shortened to a limit, a part of the top rod 411110 still protrudes from the end surface 4112. At this time, the convex-type element 41111 may continue to be pushed to enable the top rod 411110 (or in another embodiment, the end surface 4112 of the second tube body 40 directly) to push the concave position of the can body bottom portion A5 of the irritant gas can A, so that the top rod 411110 and the can body bottom portion A5 are tightly joined, so as to transfer a maximum pushing force. The pressing ring portion A2 is subject to a pushing force from behind, and the recessed seat 21 in front blocks and limits the can body top portion A4. Therefore, the compression elastic piece 30 is shortened to a limit, so as to spray the contents A3 from the output tube A1.
In addition, to keep a spray path of the irritant gas can A unobstructed, when a defense spray function is not used, an end plug 22 inserted in the through hole 211 is further included on a surface, opposite the receiving chamber 111, of the cap 20; however, before the defense spray function is used, the end plug 22 must be removed.
Please continue to refer to FIG. 5, FIG. 6, and FIG. 7. An interlocking telescopic rod-type defense spray apparatus 1a in this embodiment has members such as a first tube body 10a, a head-end portion 11a, a cap 20a, a second tube body 40a, a rod body portion 41a, and a sheath structure 4121a in the foregoing corresponding embodiment of two sectioned rods, and further includes an umbrella component 50a to form an umbrella-type defense spray apparatus. The umbrella component 50a includes: a central rod 501a, an umbrella cap 502a, an umbrella handle 503a, a notch 51a, a rib 52a, a cloth 53a, multiple tips 54a, a runner 55a, and a lengthened lower spring 56 for fastening or unfastening the runner 55a. A rod body that includes the first tube body 10a and the second tube body 40a forms the central rod 501a of the umbrella component 50a, the cap 20a forms the umbrella cap 502a of the umbrella component 50a, the sheath structure 4121a forms the umbrella handle 503a of the umbrella component 50a, the notch 51a is sleeved over the head-end portion 11a of the first tube body 10a, the lengthened lower spring 56 is disposed at a lower tube 412a of the second tube body 40a, the runner 55a is disposed between the notch 51a and the lengthened lower spring 56 and is axially slideable on peripheral surfaces of the first tube body 10a and the lower tube 412a (that is, the central rod 501a) of the second tube body 40a, the rib 52a is connected between the notch 51a and the runner 55a, and the cloth 53a and the tips 54a are disposed on the rib 52a. The cloth 53a is opened when the runner 55a moves to a side of the notch 51a, and the cloth 53a is folded when the runner 55a moves to the lengthened lower spring 56. For a manner in which the lengthened lower spring 56 is fastened to the runner 55a, multiple fastening holes 551a that can be fastened to the lengthened lower spring 56 are provided around the runner 55a at a periphery corresponding to the rod body portion 41a. In this way, each time when the lower tube 412a is rotated to a different angle from the first tube body 10a because the lower tube 412a is locked to the first tube body 10a by using the telescopic-rod packing device 413, the lengthened lower spring 56 that turns in a direction accordingly may still be fastened to one of the multiple fastening holes 551a corresponding to the runner 55a. In addition, as shown in FIG. 6, to make it still possible to perform actions of releasing locking between the first tube body 10a and the second tube body 40a and pushing the second tube body 40a forward when the lengthened lower spring 56 and the runner 55a are fastened, a length between a press button 561 of the lengthened lower spring 56 and a hook plate 562 of the lengthened lower spring 56 needs to be increased. A distance between the press button 561 and the hook plate 562 of the lengthened lower spring 56 is greater than or equal to a pushing distance by which the second tube body 40a pushes the first tube body 10a to spray contents A3 of the irritant gas can A, so that after the user presses the press button 561, the lower tube 412a is rotated for unlocking and pushed forward to perform a spray action.
Please refer to FIG. 8. An interlocking telescopic rod-type defense spray apparatus 1b in this embodiment includes members such as a first tube body 10b, a head-end portion 11b, a cap 20b, a compression elastic piece 30b, a second tube body 40b, a rod body portion 41b, and a sheath structure 4121b in the foregoing corresponding embodiment of two sectioned rods, and further includes an umbrella component 50b to form an umbrella-type defense spray apparatus. The umbrella component 50b includes: a central rod 501b, an umbrella cap 502b, an umbrella handle 503b, a notch 51b, a rib 52b, a cloth 53b, multiple tips 54b, a runner 55b, and an upper spring 57 for fastening or unfastening the runner 55b. A rod body that includes the first tube body 10b and the second tube body 40b is turned around (that is, a lower tube of a second rod body is in front, and a first rod body is behind) to form the central rod 501b of the umbrella component 50b, the sheath structure 4121b forms the umbrella cap 502b of the umbrella component 50b, the head-end portion 11b of the first tube body 10b forms the umbrella handle 503b of the umbrella component 50b, the notch 51b is disposed on an adjacent side of the sheath structure 4121b of the second tube body 40b, and the runner 55b is disposed at a periphery of the first tube body 10b and is slideable on a periphery (the central rod 501b) of a lower tube 412b of the second tube body 40b. However, a diameter of a tube body, at which the upper spring 57 is disposed, on an upper segment of the second tube body 40b should be greater than a diameter of a tube path of a lower segment of the second tube body 40b (however, for a length of a relatively long tube path of the upper segment of the second tube body 40b, a length of an original tube diameter needed for pushing between the first tube body 10b and the irritant gas can A to spray the contents A3 still needs to be reserved) to fit the runner 55b—wherein the upper segment of the second tube body 40b is an enlarged tube body 40b1. The upper spring 57 is disposed at a relatively long tube path of the upper segment of the second tube body 40b, the rib 52b is connected between the notch 51b and the runner 55b and, and the cloth 53b and the tips 54b are disposed on the rib 52b. When the runner 55b slides to the upper spring 57, the upper spring 57 may be hooked to multiple fastening holes 551b provided around the runner 55b, so as to open the cloth 53b, and the cloth 53b is folded when the runner 55b moves downward to the first tube body 10b. In such a form, after locking between the first tube body 10b and the second tube body 40b is released, the first tube body 10b and the lower tube 412b may be separately held and pushed to each other, so that the contents A3 of the irritant gas can A can be sprayed from an end surface of the umbrella handle 503b (that is, the cap 20b of the first tube body 10b) (similarly, an end plug 22b for dust-proof and water-proof purposes needs to be pulled off first).
Please refer to FIG. 9 and FIG. 10. An interlocking telescopic rod-type defense spray apparatus 1c in this embodiment includes members such as a first tube body 10c, a head-end portion 11c, a cap 20c, a compression elastic piece 30c, a second tube body 40c, a rod body portion 41c, and a sheath structure 4121c in the foregoing corresponding embodiment of two sectioned rods, and further includes an umbrella component 50c to form an umbrella-type defense spray apparatus.

Moreover, as shown in FIG. 17 and FIG. 18, to prevent the user from accidentally touching the foregoing the circuit switch 76 to cause the electrode needles 74 and the electrode plates 741 to generate an electric shock, the circuit switch 76 may include a button locking structure 762, so that in only an unlocked state of the button locking structure 762, the circuit switch 76 can be used to energize a power path by using a press-down switch button 761. In practice, the groove 4122 for receiving the circuit switch 76 is a groove hole perpendicular to a central axis direction of the lower tube 412e. The circuit switch 76 includes a press-down switch button 761 and a button locking structure 762. The button locking structure 762 can move along the groove 4122, and a fork portion 7621 is provided at an end of the button locking structure 762. By means of movement of the button locking structure 762, the fork portion 7621 is kept against a push-down path of the press-down switch button 761 (to limit energization using the circuit switch 76) or removed from the push-down path (to release a limit on energization using the circuit switch 76).
Please refer to FIG. 19 and FIG. 20 again. In an actual use example of the foregoing electric-shock-baton-type defense spray apparatus 1e, an end plug 22e may be removed first, and locking between the first tube body 10e and the second tube body 40e is then released. By means of a defense spray function of the defense spray apparatus 1e, the contents A3 of the irritant gas can A are sprayed from the through hole 211e on an end surface of the cap 20e, so that defense spray is sprayed at a villain (as shown in FIG. 19). Next, the first tube body 10e and the second tube body 40e are then locked, and the circuit switch 76 is closed to give the villain an electric shock by using the electrode needles 74 and the electrode plates 741 (as shown in FIG. 20).
It should be noted that, by means of the present invention, in addition to the foregoing that a defense spray apparatus is integrated with a function of a staff, an umbrella, a cane, a flashlight or an electrode rod, an upper tube may be further shortened to reduce a volume to achieve higher portability. Certainly, the present invention may also be disguised as a golf-club defense spray apparatus 1f. A club handle end is used as a first tube body 10f, and a ball head end used as a second tube body 40f is pressed to spray defense spray from the club handle end, as shown in FIG. 21.
