Description

Technology Field

[0001] The present invention relates to an observation device, and more specifically, to a large-aperture observation binocular device that stably supports a large-aperture binocular body while allowing the user to easily adjust and maintain the desired vertical and horizontal angles. Background Technology

[0002] Generally, binoculars are optical devices designed to magnify and observe distant objects, configured with a pair of left and right optical systems to enable the user to secure a stereoscopic field of view. Such binoculars are widely used in various fields, including nature observation, harbor or maritime surveillance, rescue operations, military surveillance, facility security, identification of aircraft or vessels, and astronomical observation. In particular, large-aperture binoculars with large objective lens diameters may be preferred when the observed object requires long distances or fine identification.

[0003] Compared to standard portable binoculars, large-aperture observation binoculars feature larger effective objective lenses, allowing them to capture more light. Consequently, they offer relatively superior visibility even in low-light or nighttime environments. Furthermore, they enable high-magnification operation and are advantageous for improving resolution and detail for distant objects, making them suitable for precise observation or long-term monitoring. However, along with these advantages, the enlargement of the lens system and housing structure leads to increased overall volume and weight, presenting the challenge of being unable to stably support the binoculars for extended periods using only the user's hands.

[0004] In particular, large-aperture binoculars have heavy bodies and require precise optical system placement, so observation performance can easily deteriorate due to hand tremor or user fatigue. As magnification increases, even minute shaking is significantly amplified in the field of view, making it difficult for users to stably track desired observation targets or maintain a constant line of sight. For this reason, large-aperture observation binoculars are generally operated while supported by a separate mounting frame, tripod, support column, or dedicated mount structure.

[0005] Conventional mounted binocular devices generally feature a structure in which the binocular body is fixed to a frame and the frame itself is rotated in a vertical or horizontal direction. However, such conventional structures can lead to reduced ease of assembly and increased manufacturing costs due to complex axis structures of the rotating parts or the overlapping of multiple fastening components. Furthermore, as the structure becomes more complex, it becomes difficult to achieve the desired degree of rotational resistance, and problems such as reduced reproducibility after adjustment may also arise.

[0006] Moreover, unlike general small optical instruments, large-aperture binoculars have a large center of gravity and a large moment acting during rotation, making it difficult to stably maintain the desired viewing angle with only a simple hinge structure or weak fastening force. For example, when a user releases their hand after adjusting the vertical angle of the binoculars, the angle may gradually change or suddenly tilt due to the weight of the body. This phenomenon not only reduces the accuracy of observation but can also cause damage to expensive optical equipment, potentially leading to a decrease in durability.

[0007] To improve this, a method of applying frictional force to the pivot point has been widely used in the past. That is, by applying a constant clamping force to the member around the pivot point, it provides appropriate resistance during rotation and maintains a selected angle in a stationary state. However, with this conventional friction fixing method, if any of the friction-generating members rotate together, the actual fixing force may decrease, and there is a risk that the fastening part may loosen or the friction state may become uneven with repeated use.

[0008] In particular, in structures where the fixed member is not reliably prevented from rotating relative to the frame, the fixed member may rotate in an unintended direction during the process of tightening or loosening the central axis. In this case, not only is assembly convenience reduced, but the pressure required to act on the rotating member cannot be stably formed, leading to a problem where friction torque cannot be precisely controlled. Furthermore, in structures with insufficient anti-rotation functionality, the fastening state is prone to fluctuating after prolonged use, making it difficult to consistently maintain the same operating feel as the initial setting.

[0009] Meanwhile, for large-aperture binoculars, simply adjusting the vertical angle is not sufficient; depending on the usage environment, smooth switching of the field of view in the left and right directions is also required. For example, in operational environments such as astronomical observation, maritime observation, or terrain monitoring, it is necessary to continuously track a specific point while searching a wide area; therefore, it is important that both lateral rotation and vertical rotation are performed smoothly and stably. However, in conventional structures, vertical angle adjustment and lateral rotation adjustment were not optimized independently of each other, so there were cases where operability in one direction was good but stability in the other direction was lacking.

[0010] Furthermore, the structure in which the binocular body is attached to the frame also significantly impacts observation performance and ease of use. Due to the large size and weight of large-aperture binoculars, it may be difficult to ensure sufficient mounting stability using only simple band-type or partial-support fastening structures. In particular, if the body shakes slightly or becomes eccentric during movement, installation, or repeated adjustments, it not only causes inconvenience to the user but also makes it difficult to maintain a precise viewing direction. Therefore, a structure that stably supports both sides of the body and provides support for the bottom is required.

[0011] Furthermore, large-aperture observation binoculars require precise alignment of the left and right optical axes to fully utilize the performance of the optical system. If the left and right optical axes are not precisely aligned, users may experience overlapping images or eye strain during prolonged observation, and observation accuracy may also be reduced. Particularly in large-aperture and high-magnification environments, even minute optical axis errors can significantly impact user experience, thus increasing the need for a structure capable of precise optical axis adjustment.

[0012] In addition, large-aperture observation binoculars can be used in various locations, such as outdoor sites, observation stations, monitoring bases, and mobile operating environments, as well as for fixed indoor installations. In such cases, the convenience of moving the entire device to a desired location is also important. Conventionally, it has often been difficult to simultaneously satisfy both mobility and installability for large-aperture binoculars, and there have been issues with the cumbersome adjustment of position and fixation during the reinstallation process after moving. Therefore, there is a need for a large-aperture observation binoculars device with a new structure that can stably support the main body of the large-aperture binoculars while simultaneously improving operability for vertical and horizontal rotation, fixation reliability, optical axis alignment, and ease of movement.

[0013] The aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot be considered technology that was disclosed to the general public prior to the filing of the present invention. The problem to be solved

[0014] One embodiment of the present invention aims to provide a large-aperture observation binocular device that stably supports the large-aperture binocular body, allows the user to easily adjust the vertical angle of the binocular body to a desired position, and stably maintains it at that position.

[0015] Another objective of the present invention is to provide a large-aperture observation binocular device capable of stably implementing a friction-fixing structure of a rotating member by preventing a fixing member coupled to a mounting frame from rotating.

[0016] Another objective of the present invention is to provide a large-aperture observation binocular device capable of simultaneously ensuring smooth operation and excellent posture-maintaining performance despite the weight of the large-aperture binocular body by adjusting the frictional force and vertical rotation torque of the rotating member according to the fastening force of the central axis portion.

[0017] Another objective of the present invention is to provide a large-aperture observation binocular device that can improve observation convenience, assembly stability, and operational efficiency by providing a clamp structure that stably supports both sides of the binocular body, a lateral rotation adjustment structure, an optical axis adjustment structure, and a moving structure together. means of solving the problem

[0018] A large-aperture observation binocular device according to one embodiment of the present invention for solving the above problem may include: a binocular body; a mounting frame supporting the binocular body; a fixing member coupled to the mounting frame and having a recess formed therein; a rotating member coupled to the fixing member and rotating together with the binocular body; and a central axis member screw-coupled to the fixing member via a screw coupling part with the rotating member in between.

[0019] At this time, a metal part is formed in the mounting frame, and a key part of the fixing member engages with the metal part to fix the fixing member so that it does not rotate relative to the mounting frame. Additionally, as the central axis part is screw-coupled to the fixing member, the rotating member can be pressed and frictionally fixed between the fixing member and the central axis part, and accordingly, the vertical angle of the binocular body can be maintained at a selected position.

[0020] The central shaft portion may penetrate the rotating member and be fastened to the screw portion of the fixed member, and a head portion that presses the rotating member toward the fixed member may be formed at one end of the central shaft portion.

[0021] The above-mentioned rotating member may be formed in the shape of a plate or a disc, and may be arranged so that one side contacts the above-mentioned fixed member and the other side contacts the above-mentioned central axis. Accordingly, the vertical angle of the binocular body may be fixed by the frictional force between the two sides of the above-mentioned rotating member and the above-mentioned fixed member and central axis.

[0022] The main part of the fixed member and the protruding part of the mounting frame may be formed with shapes corresponding to each other, and accordingly, the fixed member may be prevented from rotating in the circumferential direction relative to the mounting frame.

[0023] The fixed member, the rotating member, and the central axis may each be provided as a pair on the left and right sides of the binocular body.

[0024] The above binoculars body may include an objective lens section for focusing light on an object to be observed, an eyepiece section where the user's eye is located, and an eyepiece lens provided in the eyepiece section.

[0025] The mounting frame may include a first clamp part and a second clamp part that support each of the two sides of the binocular body, a first fixing knob and a second fixing knob provided respectively in the first clamp part and the second clamp part to selectively fix the binocular body, and a seating part that supports the lower part of the binocular body.

[0026] The first clamp portion and the second clamp portion may each be formed as an annular clamp having an opening, and a first fastening piece may be provided at the opening end of the first clamp portion, and a second fastening piece may be provided at the opening end of the second clamp portion.

[0027] The above large-aperture observation binocular device may further include a support column, and the mounting frame may be rotatably coupled to a flange portion coupled to the top of the support column in a transverse direction, and may include a rotation control knob that selectively restricts transverse rotation between the flange portion and the mounting frame.

[0028] The binocular body may further include an optical axis adjustment unit for adjusting the alignment of the optical axes of the left and right optical systems. The optical axis adjustment unit may include an eccentric ring rotatably coupled to the binocular body and a lens support member whose position is adjusted by the eccentric ring, and the optical axis may be adjusted by moving the center position of the lens support member according to the rotation of the eccentric ring.

[0029] A movable base can be attached to the bottom of the above support column.

[0030] The above-mentioned movable base may include a plurality of wheels.

[0031] A protruding part that engages with a concave part of the fixing member may be formed on the upper part of the mounting frame, and a screw coupling part to which the central shaft part is fastened may be formed on the fixing member.

[0032] The above-mentioned pivot member is interposed between the above-mentioned fixed member and the above-mentioned central axis member and is coupled to the side of the above-mentioned binocular body, so that the above-mentioned binocular body can rotate in the up-and-down direction around the above-mentioned central axis member.

[0033] The frictional force between the fixed member and the rotating member can be varied according to the fastening force of the central shaft portion, and accordingly, the vertical rotation torque of the binocular body can be adjusted. Effects of the invention

[0034] According to one embodiment of the present invention, through a structure comprising a fixed member coupled to a mounting frame, a rotating member rotating together with a binocular body, and a central axis member screw-coupled to the fixed member, the vertical angle of the binocular body can be easily adjusted and stably maintained at a selected position.

[0035] In addition, since the iron part formed on the mounting frame and the recessed part of the fixing member interlock with each other, rotation of the fixing member can be prevented, so the pressing force caused by the fastening force of the central shaft part is transmitted to the rotating member more stably, and the reliability of the friction fixing structure can be improved.

[0036] In addition, due to a structure in which the rotating member is pressed and frictionally fixed between the fixed member and the central axis, the vertical angle can be maintained without a separate complex locking device, and the structure can be simplified and assembly improved.

[0037] In addition, since the frictional force between the fixed member and the rotating member can be varied according to the fastening force of the central axis, the vertical rotation torque can be appropriately adjusted to suit the usage environment or the weight of the binocular body.

[0038] In addition, since a fixed member, a rotating member, and a central axis are provided as a pair on each of the left and right sides of the binocular body, the large-aperture binocular body can be supported more evenly and stability during rotation can be improved.

[0039] In addition, the mounting frame includes a first clamp part, a second clamp part, a first fixing knob, a second fixing knob, and a seating part, thereby allowing the binocular body to be mounted and fixed more stably.

[0040] In addition, the mounting frame is rotatably coupled to the flange portion at the top of the support column and includes a rotation control knob, thereby allowing the lateral rotation of the binocular body to be selectively adjusted or restricted, which can improve ease of use.

[0041] In addition, since the optical axis adjustment unit includes an eccentric ring and a lens support, the center position of the lens support is moved according to the rotation of the eccentric ring, thereby allowing for precise adjustment of the optical axis alignment of the left and right optical systems.

[0042] In addition, a movable base is coupled to the bottom of the support column, and since the movable base includes multiple wheels, the installation and movement of the large-aperture observation binoculars device can be made easier.

[0043] The effects of the present invention are not limited to those mentioned above. Brief explanation of the drawing

Specific details for implementing the invention

[0045] The present invention may be modified in various ways and may have various embodiments; therefore, specific embodiments are illustrated in the drawings and described in detail.

These terms are used solely for the purpose of distinguishing one component from another.

[0048] FIG. 1 is a perspective view showing the overall configuration of a large-aperture observation binocular device according to one embodiment of the present invention.

[0049] Referring to FIG. 1, a large-aperture observation binocular device (100) may have a structure in which a mounting frame (20) is attached to the top of a support column (30) that extends vertically, and a binocular body (10) is mounted on the mounting frame (20). The support column (30) may function as a main support structure to secure the installation height of the device and may be able to separate the binocular body (10) from the ground or floor surface to near the user's line of sight height. The support column (30) may be formed as a cylindrical column and may be formed of a metal material capable of securing bending rigidity and compressive rigidity.

[0050] The mounting frame (20) can be positioned at the top of the support column (30) and function as a configuration that substantially supports the binocular body (10). The mounting frame (20) may have a seating structure that supports the lower part of the binocular body (10) and a side support structure that supports the left and right sides of the binocular body (10). A first fixing knob (21a) and a second fixing knob (21b) may be positioned on the upper sides of the mounting frame (20), and the first fixing knob (21a) and the second fixing knob (21b) may function as fastening means to fix the binocular body (10) to the mounting frame (20). When the degree of tightening of the first fixing knob (21a) and the second fixing knob (21b) increases, the binocular body (10) can be maintained in a state where shaking is suppressed relative to the mounting frame (20).

[0051] The binocular body (10) can be positioned lengthwise in the front-rear direction while supported by the mounting frame (20). The center of gravity of the binocular body (10) can be set to be located near the seating area of ​​the mounting frame (20). This arrangement can contribute to distributing the rotational load evenly to the left and right rotation axes when the binocular body (10) rotates up and down.

[0052] A movable base (50) may be attached to the bottom of the support column (30). The movable base (50) can transfer the load of the support column (30) to the floor surface while enabling the movement of the entire device. A plurality of wheels (51) may be arranged on the outer periphery of the movable base (50). The wheels (51) can reduce resistance to movement when changing the installation position of the device and can improve the handling of heavy devices, such as large-aperture binoculars. The movable base (50) may be formed as a plate-shaped or stepped base with a wide outer diameter to ensure resistance to overturning moments.

[0053] FIG. 2 is a perspective view showing the configuration of a binoculars body according to one embodiment of the present invention.

[0054] Referring to FIG. 2, the binocular body (10) may be formed as an optical body including a pair of optical tubes. An objective lens section (11) may be provided at one end of the binocular body (10), and an eyepiece section (12) and an eyepiece lens (13) may be provided at the other end. The objective lens section (11) may collect light incident from an object to be observed and transmit it to an internal optical system. The eyepiece section (12) may form an area where the user's eye is located, and the eyepiece lens (13) may emit light transmitted from the internal optical system so that the user can observe it.

[0055] The binocular body (10) may have a structure in which left and right optical tubes are arranged side by side. Each optical tube may be formed in a cylindrical or polygonal tubular shape on its outer surface, and a connecting body may be provided in the central part to integrally connect the two optical tubes. The connecting body can maintain the distance between the left and right optical tubes and secure structural rigidity. As shown in FIG. 2, the outer shape of the binocular body (10) may have a rectangular shape extending from the front objective lens side to the rear eyepiece side, and may have an outer shape that is easy to combine with the clamp structure of the mounting frame (20).

[0056] Although not explicitly illustrated in FIG. 2, the binocular body (10) may further include an optical axis adjustment unit that corrects the alignment of the optical axes of the left and right optical systems as needed. The optical axis adjustment unit may include an eccentric ring and a lens support. When the eccentric ring is rotated, the center position of the lens support can be moved by the amount of eccentricity, and accordingly, the optical axis of each optical tube can be finely adjusted. The optical axis adjustment unit can contribute to reducing diplopia during observation and reducing fatigue during long-term use.

[0057] The left and right sides of the binocular body (10) can be combined with a pivot member (44). The pivot member (44) can provide a center of rotation while fixed to the side of the binocular body (10), and can form an up-and-down rotation structure by cooperating with the fixed member (40) via the center axis portion (43). Therefore, the binocular body (10) can be supported in a state where it is not completely fixed to the mounting frame (20), but rather can be supported in a state where the angle in the up-and-down direction can be adjusted around the pivot axis defined on the left and right sides.

[0058] FIG. 3 is a perspective view showing a support structure including a mounting frame and a flange portion according to one embodiment of the present invention.

[0059] Referring to FIG. 3, the mounting frame (20) may include a first fixing knob (21a), a second fixing knob (21b), a first clamp part (22a), a second clamp part (22b), a first fastening piece (23a), a second fastening piece (23b), a seating part (24), a connecting part (25), a rotation adjustment knob (26), and a flange part (27).

[0060] The first clamp part (22a) and the second clamp part (22b) can each be formed as an annular clamp having an opening. Since the annular clamp structure can surround and support a portion of the left and right outer surface of the binocular body (10), a contact surface wider than line contact can be secured. Accordingly, local stress acting on the binocular body (10) can be relieved. A first fastening piece (23a) may be provided at the opening end of the first clamp part (22a), and a second fastening piece (23b) may be provided at the opening end of the second clamp part (22b). The first fastening piece (23a) and the second fastening piece (23b) can function as fastening points that adjust the opening width of each clamp part.

[0061] The first fixing knob (21a) is coupled to the first clamp part (22a) to adjust the tightening state of the first clamp part (22a). The second fixing knob (21b) is coupled to the second clamp part (22b) to adjust the tightening state of the second clamp part (22b). When the user tightens the first fixing knob (21a) and the second fixing knob (21b), the opening width of each clamp part is reduced, allowing pressure to be applied to both outer peripheries of the binocular body (10). When the user loosens the first fixing knob (21a) and the second fixing knob (21b), the opening width of each clamp part is expanded, allowing the binocular body (10) to be detached.

[0062] The mounting portion (24) is formed at the lower center of the mounting frame (20) to support the lower part of the binocular body (10). The mounting portion (24) may have a recessed shape or an inclined support surface corresponding to the lower outer shape of the binocular body (10). The mounting portion (24) supports the load of the binocular body (10) downward and can cooperate with the lateral fixing function performed by the left and right clamp portions. With this structure, the binocular body (10) can be simultaneously supported downward and fixed sideways.

[0063] The connecting part (25) can be formed as a lower structure connecting the mounting frame (20) and the flange part (27). The connecting part (25) can transmit a load transmitted from the mounting frame (20) to the flange part (27). A rotation control knob (26) is positioned near the connecting part (25) or the flange part (27) to control the lateral rotational resistance between the mounting frame (20) and the flange part (27). When the user tightens the rotation control knob (26), the lateral rotation of the mounting frame (20) can be restricted, and when the user loosens the rotation control knob (26), the mounting frame (20) can rotate left and right relative to the flange part (27).

[0064] The flange portion (27) may be formed as a disc-shaped or frustoconical member that is coupled to the top of the support column (30). The flange portion (27) can support the mounting frame (20) so as to be rotatable in the lateral direction and can be firmly coupled to the support column (30) through a bolt fastening portion. The flange portion (27) can serve to transmit the load of the mounting frame (20), the weight of the binocular body (10), and the operating load applied by the user during observation to the support column (30).

[0065] FIG. 4 is a perspective view showing the configuration of a fixing member according to one embodiment of the present invention.

[0066] Referring to FIG. 4, the fixing member (40) may be formed as a member that is coupled to the side pivoting structure of the mounting frame (20). The fixing member (40) may have a recess (41) and a screw coupling part (42) formed therein. The recess (41) may be provided in a shape that engages with the protruding part (28) formed on the mounting frame (20). The screw coupling part (42) may be formed as a female screw structure to which the central shaft part (43) is fastened, or a fastening structure equivalent thereto.

[0067] The fixing member (40) can be formed as a body including a disc-shaped flange portion when viewed from the outside, and can have a constant thickness in the axial direction. One side of the fixing member (40) can be positioned on the mounting frame (20) side, and the other side can be positioned on the rotating member (44) and the central axis portion (43) side. The screw coupling portion (42) is formed in a direction parallel to the rotation axis direction to allow fastening of the central axis portion (43).

[0068] The recess (41) may be formed in a shape where a part of the fixing member (40) is cut off, a groove shape, or a concave joint shape. The recess (41) may be formed to correspond in shape to the protruding part (28) of the mounting frame (20). Due to this correspondence in shape, the fixing member (40) may be prevented from rotating arbitrarily in the circumferential direction after being mounted on the mounting frame (20). Therefore, when tightening or loosening the central axis part (43), the phenomenon of the fixing member (40) rotating together can be prevented, and the tightening force can be easily adjusted.

[0069] A fixed member (40) may be placed on the left and right sides, respectively. A pair of left and right fixed members (40) can form a pivot axis structure on both sides of the binocular body (10) and can distribute and support the weight of the binocular body (10) from the left and right sides. This structure can contribute to reducing pivot axis load even when the weight increases, such as in a large-aperture binocular body (10).

[0070] FIG. 5 is a partial enlarged view showing a structure in which a fixed member, a rotating member, and a central axis part are combined with a metal part of a mounting frame according to one embodiment of the present invention so that the vertical angle of the binocular body is adjusted.

[0071] Referring to FIG. 5, the fixed member (40), the central axis part (43), the rotating member (44), and the protruding part (28) of the mounting frame (20) can form an up-and-down angle adjustment structure of the binocular body (10). The protruding part (28) may be formed protrudingly on the upper part of the mounting frame (20). The protruding part (28) may have a protruding shape that can engage with the recessed part (41) of the fixed member (40). When the fixed member (40) is placed on the mounting frame (20), the recessed part (41) and the protruding part (28) may be fitted together or engaged. In this combined state, rotation of the fixed member (40) relative to the mounting frame (20) may be restricted.

[0072] The rotating member (44) may be interposed between the fixed member (40) and the central axis portion (43). The rotating member (44) may be formed in a plate shape or a circular shape, and one side of the rotating member (44) may be in contact with the fixed member (40), and the other side of the rotating member (44) may be in contact with the head portion of the central axis portion (43). Since the rotating member (44) may be coupled to the side of the binocular body (10), when the rotating member (44) rotates, the binocular body (10) may also rotate together.

[0073] The central shaft portion (43) can be fastened to the screw coupling portion (42) of the fixed member (40) by penetrating the rotating member (44). A head portion may be formed at one end of the central shaft portion (43), and this head portion can press the rotating member (44) toward the fixed member (40) when fastened. The deeper the central shaft portion (43) is fastened to the screw coupling portion (42), the greater the axial pressure the rotating member (44) can receive between the fixed member (40) and the central shaft portion (43). As a result, frictional force can be increased on both sides of the rotating member (44).

[0074] The frictional force of the rotating member (44) can determine the vertical rotational torque of the binocular body (10). To rotate the binocular body (10) upward or downward, the user may need to apply a force to overcome the frictional force between the rotating member (44) and the fixed member (40), and between the rotating member (44) and the central axis (43). If the fastening force of the central axis (43) increases, the frictional force increases, so the vertical angle of the binocular body (10) may not change easily. If the fastening force of the central axis (43) decreases, the frictional force decreases, so the user can change the angle of the binocular body (10) with less force.

[0075] According to the structure illustrated in FIG. 5, the members that allow rotation are the rotating member (44) and the binocular body (10), and the fixed member (40) can be maintained in a fixed state on the mounting frame (20) by engaging with the iron part (28). Therefore, the adjustment of the fastening force and the rotation function may not interfere with each other. Since the fixed member (40) does not rotate, the fastening force of the central axis part (43) can be directly reflected in the adjustment of the friction torque. This structure can maintain a selected vertical angle without a separate complex toothed fixing member, ratchet structure, or multiple locking members.

[0076] The protruding part (28) and the lumbar part (41) can be formed with corresponding shapes. The corresponding shapes may be curved surfaces, flat surfaces, cut surfaces, or combined shapes capable of forming a circumferential lock. These corresponding shapes can define the assembly position of the fixing member (40) and prevent displacement after assembly. Since the fixing member (40) remains stationary while the rotating member (44) rotates, the vertical angle of the binocular body (10) can be maintained at a position set by the user.

[0077] A fixed member (40), a central axis member (43), and a pivot member (44) of the same structure may be respectively arranged on the left and right sides of the binocular body (10). A pair of left and right pivot structures can form an up-and-down pivot axis of the binocular body (10) on both sides and can distribute the load generated during rotation to the left and right sides. Accordingly, tilting, uneven wear, and axial eccentricity of the binocular body (10) can be suppressed. In addition, since a pair of left and right friction surfaces act simultaneously, the holding force at a selected up-and-down angle can be improved.

[0078] The user can move the large-aperture observation binocular device (100) to a desired position using the wheels (51) of the movable base (50). The user can select the degree of lateral rotational freedom of the mounting frame (20) by adjusting the rotation control knob (26) of the mounting frame (20). The user can fix the binocular body (10) to the mounting frame (20) by adjusting the first fixing knob (21a) and the second fixing knob (21b). The user can then rotate the binocular body (10) in the up and down direction to set an angle corresponding to the altitude of the object to be observed. At this time, the rotating member (44) can rotate around the central axis part (43), and the frictional force generated by the fastening force of the central axis part (43) can maintain the set angle.

[0079] The large-aperture observation binocular device (100) configured in this manner can accommodate the increase in weight resulting from the enlargement of the binocular body (10). The mounting frame (20) can support the binocular body (10) from the bottom and side, and the fixing member (40), the rotating member (44), and the central axis part (43) can implement up-and-down rotation and angle maintenance functions with a simple structure. The interlocking structure of the iron part (28) and the lumbar part (41) can suppress unnecessary rotation of the fixing member (40), and the rotation torque can be controlled by adjusting the fastening force of the central axis part (43). Therefore, the user can select the posture of the binocular body (10) according to the observation conditions, and the selected posture can not be easily deformed by external forces.

[0080] Although the embodiments have been described above with reference to limited examples and drawings, those skilled in the art can make various modifications and variations from the description above. For example, the shape, arrangement, connection relationship, or material of the described components may be changed without departing from the technical spirit of the present invention, and some components may be replaced or added by other components or equivalents.

[0081] Therefore, other embodiments and configurations equivalent to the claims also fall within the scope of the claims described below. Explanation of the symbols
