The invention lies in the field of stands for target, for example, those dedicated to support targets for aiming and shooting practice.
In particular, the invention relates to a portable target stand comprising a base aimed to be deployed over a surface in a usage position.
Target stands are used for supporting targets form aiming practice, for example, for shooting firearms, arrows, or the like. Typical stands known in the art are fixed structures that provide a good stability but that are difficult to transport and manipulate. For this reason, some other solutions of foldable stands have been developed. Examples of these type of target stands are diverse in the art, the most usual being trestles to tripods. For example, U.S. Pat. No. 10,295,315 discloses a trestle-like target stand with four foldable legs. U.S. Pat. No. 5,503,356 discloses a tripod-like target stand having three foldable legs. These types of stans are portable, they can be unfolded and deployed over a surface and, when the aiming session finishes, they can be folded back so they can be transported, stored, or moved to another location.
However, in these types of stands, the structure is still large to be easily transported even when folded. Another problem is the lack of adaptation to the terrain or surface where the stand has to be deployed. U.S. Pat. No. 8,955,846 discloses a tripod stand having a base with three foldable legs and yoke gimbal assembly that allows to deploy the base in an uneven terrain and support the target in a vertical position. U.S. Pat. No. 8,176,665 discloses stands having a base having an elongated body and a leg formed in a single piece articulately joined at the middle, so it can be horizontally unfolded in a X-like shape or folded against the body for storage and transportation. Several bases may be jointly used in order to improve stability. Even if the aforementioned examples provide improved transportation and storage capabilities, the adaptation to the terrain is still limited.
A further problem of many of the stands known in the art is that the required rigidity and stability often requires using metallic parts. In particular, in the case of targets for firearm shooting practice, when a projectile impacts a metallic part, it can generate shards that may fly away and be a potential risk. US20190186874 deals with this shortcoming by using a stand formed by flat pieces of multilayer polymeric material that can be assembled together, the pieces having a low-density polymer foam in the centre, so it can absorb impacts without creating shards. The resulting stand, however, is not suitable for being deployed in uneven terrains and the type of targets it can support is limited.
The invention is aimed to provide portable target stand of the type stated at the beginning, being able to avoid the problems that have been identified above.
This purpose is achieved by a portable target stand of the type indicated at the beginning, wherein said base comprises:
The base may therefore be deployed showing a front side that will usually be directed towards the location of the person who is practicing shooting, and a back side opposite the front side. Each of the four legs have two portions: the first portion is articulated regarding the body and can be folded and unfolded horizontally with respect to the body, while the second portion is articulated regarding the first portion and can be folded and unfolded vertically with respect to the first portion. As a non-limiting example, one end of the first portion of each leg may be attached near one to the ends of the body by an articulation element, and the other end of the first portion may be attached to one end of the second portion of the leg by another articulation element. This way, when unfolded, the free end of the second portion may be in contact with the surface where the base is deployed. Since each portion of each leg may be unfolded independently and into different angles, the resulting stand may be easily adapted to uneven surfaces, even to stairs. At the same time, because all the legs fold regarding themselves and to the body, the stand may be folded into a compact shape that it is easy to transport and store.
Preferably, each of said second portions is provided with a through-hole configured to allow the passage of a fixing element, for example, a nail or a bolt, for fixing said base to said surface, thereby improving the stability.
Preferably, each of said legs is formed independently of one another, therefore, the legs do not share parts in common and may be actuated independently and even replaced independently from one another.
Preferably, each of said first portions are horizontally tiltable independent from one another, so that each leg can be folded and unfolded independently form one another. As an alternative, the legs may be associated in pairs, so one of the legs in a pair may be unfolded until one leg comes full-tilt against the other leg of the pair. This effect may also be obtained by the presence of a stopping element arranged between the legs as it will be shown in the latter examples and figures.
Preferably, each of said second portions are vertically tiltable independent from one another, so they can be folded and unfolded independently from one another, therefore improving possibilities of adaptation to the surface where the portable stand will be deployed.
Preferably, in said first extended position said first portion is tilted away laterally from said body in an angle of at least 120°.
Preferably, in said second extended position said second portion is tilted away downwards from said first portion in an angle of 165°, so that to obtain a range of angles that may be adapted to the surface and that, when the surface is completely flat and horizontal, the body remains a bit elevated over said surface.
Preferably, each of said first portions are each lockable at least in said first folded position and/or said first extended position. The possibility of looking the first portions in the folded position facilitates the transportation and storage, while the possibility of locking in the unfolded position improves stability when deployed. Preferably, each of said second portions are each lockable at least in said second folded position and/or said second extended position, with equivalent effects to the ones regarding the first portions.
Preferably, each of said first portions are each lockable in at least one first tilted position between said first folded position and said first extended position, i.e., in an intermediate position, and more preferably in several intermediate positions, so that it is possible to improve the stability in a plurality of intermediate angles, thereby increasing the flexibility to adapt to uneven surfaces and terrains. Likewise, in a preferred embodiment, each of said second portions are each lockable in at least one second tilted position between said second folded position and said second extended position.
Preferably, in each leg, said first portion is attached to said second portion by means of a toothed hirth-like joint, having two parallel disks, each having teeth that extend towards the other disk, so that the teeth of both disks are confronted and engage with each other to lock the joint into position. This is a particularly advantageous type of joint that allows to position the second portion in the desired tilted position and safely block it into position, preventing undesired rotation afterwards.
Preferably, said hirth-like joint has a manually operable locking element of at least 2 cm wide, so it can be manually operated even without using dedicated tools. A size of at least 3.5 cm is advantageous for operating the locking element with gloves.
Preferably, each leg has a graded angle display scale comprising a scale of values at regular intervals, so that each value corresponds to a tilting angle of said second portion, so that each second portion may be tilted to the exact angle, if necessary, for example, if the surface is completely flat it may be necessary that all the second portions are positioned to the same angle.
Preferably, each of said first portions and, therefore, each leg, is attached to said body by means of a swivel attachment, so that the first portions can be folded and unfolded in their respective positions. Different options for the swivel attachment may be envisaged, for example, those based on a screw inserted in one end of the first portion. Other embodiments will be discussed hereinafter.
Preferably, each of said swivel attachments has a manually operable locking element of at least 2 cm wide, so that it can be manipulated without dedicated tools. A size of at least 3.5 cm is advantageous for operating the locking element with gloves.
Preferably, said body comprises:
Preferably, said elongated body comprises:
Preferably, each of said end part securing means comprises a dovetail junction and a lock, which provides a secure attaching mechanism, but which is also easy to operate.
Preferably, for each pair of legs of said two pairs of legs, one leg of said pair of legs, in particular, the corresponding first portion, is horizontally tiltable from said first folded position to said first extended position in a forward direction, and the other leg of said pair of legs is horizontally tiltable from said first folded position to said first extended position in a backward direction, contrary to said forward direction, so that each leg of each pair of legs folds and unfolds in the opposite direction regarding the other leg of the pair, one forwards and one backwards. The side identified as the front of the elongated body is the one facing the practicing shooter in a normal usage position, and the back is the opposite side. Therefore, the directions identified with the words “forward” and “backward” have been referred to said front and back sides. The skilled person will understand that the word “direction” corresponds to the beginning of the movement when the leg starts to tilt from the folded position towards the unfolded position and is, therefore, parallel to the tangent of the curved line described by the leg at the point corresponding to the initial position.
Preferably, for each pair of legs of said two pairs of legs, it is provided an angular stopper configured to prevent the angle between said legs from being less than a predefined minimum angle, so that each leg of said pair of legs is horizontally tiltable independent from one another if the angle between each leg of said pair of legs is greater than said predefined angle between legs. As a non-limiting example, said stopper may be an abutment provided in the first portions of the legs proximate to the corresponding swivel attachment. Once one leg is tilted so that it reaches the stopper, said leg interferes with the other and, if it continues to be tilted away, it also tilts the other leg of the pair (towards its respective folded position) provided that the second leg is tilted in a range of angles that allow said movement. This preferred embodiment grants a minimum separation between the legs, thereby improving the stability of the portable target stand. Moreover, once the two legs of the pair are in contact, there is an additional contact point which further improves said stability.
Preferably, said predefined minimum angle is 120°, which has been found to be an adequate compromise between flexibility of position and stability for most of the situations.
Preferably, each swivel attachment of said first swivel attachment and said second swivel attachment comprises a top threaded part and a bottom threaded part, screwable with each other in a mounted position, thereby forming a vertical empty cylinder having a central axis, said empty cylinder opened to the exterior at least in a top side of said elongated body so that a mounting hole accessible by said top side is formed, wherein said central axis of said vertical cylinder is also the axis of rotation around which each leg of the pair of legs attached to the swivel attachment can be tilted;
In this preferred embodiment, each swivel attachment comprises two threaded parts that can be screwed together in order to lock the corresponding pair of legs into a particular position. When the two parts of a swivel attachment are screwed together, a cylindrical mounting hole is defined in the top side, and this mounting hole acts as part of the target attachment means for the portable target stand. This configuration provides a simple structure that minimizes the number of elements and is still robust and easy to assemble and disassemble. In a preferred embodiment the top threaded part and bottom threaded part have a diameter of at least 35 mm in order to be manually operable without the need of dedicated tools, and even with gloves.
Preferably, the portable target stand further comprises a target assembly that comprises a first pole and a second pole, wherein, in a mounted position, said first pole is inserted in said first mounting hole, and said second pole is inserted in said second mounting hole, said poles configured for holding a target between them. If the poles are straight vertical elements, it necessary that the distance between the first and second mounting holes is adequate for the size of the target that will be hold in between. The modular structure discussed above is a particularly preferred combination with this embodiment since it allows to obtain longer or shorter portable stands depending on the sizes of the modules that can be assembled.
Preferably, each of said first pole and said second pole is formed by at least two tubes that can be assembled together, thereby facilitating the adaptation to different heights of the target, and also minimizing the space necessary for storage and transport when disassembled.
Preferably, the portable target stand further comprises a target assembly that comprises a first clamp and a second clamp, each clamp having a bottom straight mounting part and top clamping part, wherein, in a mounted position, said straight mounting part of said first clamp is inserted in said first mounting hole, and said straight mounting part of said second clamp is inserted in said second mounting hole, said clamps configured for holding a target between them. This is a preferred embodiment for rigid targets that do not need a supporting structure, for example, those made of a sheet Expanded Polystyrene, EPS.
Preferably, each of said clamping parts has the general shape of an inverted R, which facilitates the insertion of rigid targets of the type described above.
Preferably, said target attaching means comprise a central mounting hole provided in a top side of said elongated body, so that it provides flexibility regarding the type of target assembly. Preferably, said central mounting hole is threaded, so that the target assembly it can be secured therein.
Preferably, the portable target stand further comprises a pendulum target assembly that comprises a U-shaped holding structure configured to hold a target, said holding structure connected to a counterweight, and rotatably attached to a vertical fork, so that it can oscillate vertically;
The target assembly disclosed herein is suitable for being used with the base of the portable target stand of the invention, but it can also be used with other types of target stands. The configuration is advantageous to adapt the target stand and target assembly to uneven surfaces, for example, in cases where the rake to the floor cannot be totally compensated by the legs of the base. The ball joint of the target assembly allows to position the target in vertical position so that the pendular movement is not impinged by the conditions of the terrain and the target and counterweight can function as expected. Pendulum targets allow shooting practice with targets that are not in a fixed position but oscillate, thereby increasing the difficulty.
Preferably, said target assembly further comprises a level indicating means, configured to show the inclination of said upper part of said ball joint, so that the compensation for any angle of inclination can be easily read and corrected.
Preferably, said level indicating means comprises a spirit level. This type of level indicating means has the advantage of a low manufacturing cost but also can be free of metal parts that could create potentially dangerous shards when receiving an impact.
Preferably, said counterweigh comprises a pole, said pole comprising one or more weight elements that can be assembled together thereby forming said pole. The modular counterweight is particularly advantageous because it allows to select the speed of the pendular motion of the target.
Preferably, said target assembly further comprises a locking bracket comprising:
Preferably, said target assembly further comprises a releasing actuator, configured to throw down said locking bracket, thereby releasing said counterweight, wherein said releasing actuator comprises at least one of:
These options provide remote access to the locking bracket, either by a shot on the secondary target or by pulling the cord attached to the locking bracket.
Preferably, said elongated body further comprises a control module shielded inside said elongated body, said control module being configured for performing at least one of:
The control module may be shielded, for example, by a block of high-density material or metal provided in front of the control module and protecting it from potential damaging shots. The presence of a control module allows several advantageous features that provide a more complete and realistic shooting practice experience, from activating lights directed to the person practicing shooting, playing some environmental or simulated combat sounds, etc. The control module may also be used to initiate the pendular movement of a pendulum target assembly by releasing the locking bracket or the locking latch.
Preferably, said target assembly further comprises a locking latch, provided in said U-shaped holding structure of said target assembly and configured for engaging with said vertical fork thus securing said U-shaped holding structure in a horizontal position. This is a minimized design that can be used for holding the structure in place without the need for external elements. Depending on the position of the latch and the way to engage with the fork, the U-shaped holding structure may be secured perfectly horizontally or with a small angle diverging from the horizontal.
Preferably, said locking latch is rotatably mounted to said U-shaped holding structure and has an unlocked position wherein said locking latch is folded to the U-shaped holding structure and retained thereto by at least one magnet, and a locked position wherein said locking latch extends perpendicularly to the U-shaped holding structure. The magnet or magnets help to keep the latch in position when folded so that the pendulum target assembly can oscillate.
Preferably, said target assembly further comprises a releasing actuator, configured to pull down said locking latch from one of its ends, so that said locking latch is moved from said locked position to said unlocked position, thereby releasing said U-shaped holding structure, wherein said releasing actuator comprises a cord configured to be attached to one end of said locking latch. Similar to the case of the locking bracket, the cord may pull the locking latch, releasing the target assembly that starts oscillating. In this case, a preferred embodiment is using a control module that drives the cord, for example, by releasing a spring that pulls the cord.
Preferably, said target stand further comprises a rotatory vertical target assembly that comprises a U-shaped holding structure configured to hold a target, said holding structure comprising two vertical poles and a horizontal bottom part; said target assembly further comprising a rotatory module configured to be inserted in said central mounting hole and having:
Preferably, said control module is configured for performing at least one pre-defined sequence, so that the additional features described above can be activated following said sequence.
Preferably, said at least one pre-defined sequence is programmable, so it can be changed by the user.
Preferably, said at least one pre-defined sequence is selected between a collection of sequences, so it can be chosen by the user between a plurality of possible sequences, or even between predefined sequences and other that the user has programmed in the control module.
Preferably, said control module is remotely activated and/or remotely controllable, so that the user can access remotely to the control module without going near the target stand. Several options may be envisaged for the remote control support, non-limiting examples are infra-red, IR, controls, using external devices communicating by wired or wireless technologies such as mobile phone data networks, Wi-Fi, Bluetooth, etc. The remote controller may also be a dedicated device, a smart device with a dedicated application installed therein or other equivalent solutions.
Preferably, the portable target stand is manufactured using mainly plastic materials, in particular, in rigid plastic materials. These types of materials are less prone to create dangerous shards when receiving an impact, thereby improving the safety of the shooting practice.
Preferably, said at least one plastic material has at least all but one of the following properties:
After extensive testing, it has been found that the materials having all the aforementioned properties are particularly well suited for maintaining the structural properties after impacts and minimizing the risks of creating potentially dangerous shards. Even materials having all but one of these properties have been found as suitable candidates for manufacturing the portable target stand and, in particular, the base.
Preferably, said plastic materials are at least one of:
After several test, it has been found that these materials are the best suited for creating a portable target stand because they can resist several impacts with minimal deformation and without creating dangerous shards. Among the different materials listed above, it has been found that the best suited are nylon, polyethylene, and polypropylene.
Preferably, each of the parts of the portable target stand has a width and height of at least 12 mm, therefore reducing the risk of breakage when receiving an impact of standard 9 mm ammunition.
