[0003] [Patent Document 1] Patent Publication No. 2021-156637 Summary of the Invention [Problem to be solved by the invention]

[0004] When installing and operating various devices (referred to as "devices to be adjusted"), such as speed measurement devices, users may adjust the installation status, such as the position and orientation of the device, or perform various settings related to its operation while checking the display on a personal digital assistant (PDA) such as a tablet computer or smartphone, which is separate from the device to be adjusted. In this case, users must hold the PDA in one hand and check the display on the PDA with the other, while adjusting the installation status, such as the position and orientation of the device to be adjusted. This can lead to problems such as dropping the PDA or making it difficult to accurately and quickly adjust the installation status, such as the position and orientation of the device to be adjusted. Furthermore, while a display is required to check the installation status and settings of the device to be adjusted during adjustment or setting, the display is unnecessary during operation after the adjustment or setting is complete. This creates a problem in that providing a display on each device to be adjusted is pointless.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a terminal holder that allows a portable information terminal to be detachably attached to a device to be adjusted. [Means for solving the problem]

[0006] In order to solve the above problem, the terminal holder according to the present invention is a terminal holder for a device to be adjusted. The device has a holding section that holds a portable information terminal having a display section that is used for adjusting and / or setting the device to be adjusted in a freely insertable and removable manner, an insertion / removal section that is inserted into and removed from a receiving section provided on the device to be adjusted, and a rotational connecting section that is interposed between the holding section and the insertion / removal section. death , The adjustment target device and the mobile information terminal are connected by wire or wirelessly, and are capable of sending and receiving information and data. It is characterized by:

[0007] The terminal holder according to the present invention may have a lock pin that is inserted through a through hole provided in the receiving portion, passes through the through hole, and is inserted into a pin hole provided in the insertion / removal portion.

[0008] In the terminal holder according to the present invention, the rotational connection portion may be a torque hinge.

[0009] In the terminal holder according to the present invention, the device to be adjusted may be attached to a pan head of a tripod.

[0010] In the terminal holder according to the present invention, the device to be adjusted may be a speed measuring device. [Effects of the Invention]

[0011] The terminal holder of this invention allows a portable information terminal to be detachably attached to a device to be adjusted, and allows the user to use both hands to adjust (especially fine-tune) the installation state, such as the position and attitude, while checking the condition of the device to be adjusted displayed on the display unit of the portable information terminal. It also eliminates the need to provide a display unit for each device to be adjusted. Furthermore, the terminal holder of this invention has a simple structure, making it easy to use and easy to handle, and less likely to malfunction even when used outdoors, thereby improving versatility.

[0012] According to the terminal holder of this invention, if it is provided with a locking pin, the locking pin acts as a support and locks the insertion / removal part so that it does not come out of the receiving part while the portable information terminal held in the holding part of the terminal holder is in use, thereby making it possible to prevent the terminal holder and the portable information terminal from falling off.

[0013] According to the terminal holder of this invention, if the rotating connecting part is a torque hinge, the angle of the holding part can be maintained after the display of the portable information terminal has been adjusted to an angle that is easy to see, and the display of the portable information terminal can be maintained in an easy-to-see state.

[0014] With the terminal holder of this invention, when the device to be adjusted is attached to the head of a tripod, it is possible to use both hands to adjust the position of the device to be adjusted by adjusting the installation position of the tripod, and to adjust the attitude of the device to be adjusted by adjusting the rotation angle and elevation angle of the head.

[0015] According to the terminal holder of the present invention, when the device to be adjusted is a speed measuring device, the above-described advantageous effects can be achieved when the speed measuring device is installed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be described below based on the illustrated embodiments. In the description of the present invention, directions such as up / down, front / back (in other words, front / back), and left / right are defined along the axes of a three-dimensional Cartesian coordinate system as shown in the drawings.

[0018] In this embodiment, as shown in FIG. 1, a case will be described in which a terminal holder 1 according to an embodiment of the present invention is attached to a speed measuring device 8 for use.

[0019] (Speed ​​measuring devices and mobile information terminals) In this embodiment, the speed measurement device 8 to which the terminal holder 1 is attached is a mechanism for measuring the speed of a moving object using radar, and mainly comprises a detection unit 81, a control unit (not shown in the figure), and an imaging unit 82. The speed measurement device 8 requires a display unit to check the installation state and setting contents when adjusting or setting up the speed measurement device 8, but the display unit is not necessary when operating the device after adjustment and setting are complete.

[0020] The detection unit 81 and the photographing unit 82 are attached to the pan head 71 of the tripod 7 and are then installed on a roadside or the like. The control unit is placed inside the trunk case 83 (for this reason, it is not shown in the figure). The speed measurement device 8 is configured so that the detection unit 81 and the photographing unit 82 can be removed from the pan head 71 of the tripod 7 and stored (together with the control unit) inside the trunk case 83 for transport.

[0021] The pan head 71 of the tripod 7 is configured so that the rotation angle and elevation angle are adjustable (specifically, rotatable around an axis in the vertical direction and rotatable around an axis in the horizontal direction).

[0022] The detection unit 81 and the control unit, and the photographing unit 82 and the control unit, may be connected by wire or wirelessly so that information and data can be sent and received.

[0023] The detector 81 emits radio waves from an irradiation window on the front surface toward the road, and captures the reflected waves that are reflected back from the surfaces of moving objects on the road, and outputs them as radar data.

[0024] The control unit calculates the speed of the moving object by processing the Doppler signal contained in the reflected wave using the radar data output from the detection unit 81. If the calculated speed exceeds a predetermined speed, the control unit outputs image storage command information to the imaging unit 82.

[0025] The photographing unit 82 includes an imaging means and photographs, through a photographing window on the front, a moving image of the area irradiated with radio waves by the detection unit 81. The photographing unit 82 then extracts a frame at the timing when image storage command information output from the control unit is input as a still image, and records the still image in a storage device such as a memory attached to the control unit. In this way, an image including an object moving faster than a predetermined speed is obtained.

[0026] The speed measuring device 8 having the above-mentioned parts measures the speed of moving objects (specifically, vehicles) on the road, and records the location, date, time, speed, etc. of moving objects that are faster than a predetermined speed, as well as recording an image including the moving object.

[0027] When installing the speed measuring device 8, the installation state of the speed measuring device 8, such as its position and posture, and various settings related to its operation are adjusted in accordance with specifications regarding the direction / orientation of the irradiation window on the front of the detection unit 81 and the photographing window on the front of the photographing unit 82 relative to the road (or vehicles traveling on the road).

[0028] A mobile information terminal 9 is used when adjusting or setting the speed measurement device 8. The speed measurement device 8 and the mobile information terminal 9 may be connected by wire or wirelessly so that they can send and receive information and data.

[0029] The mobile information terminal 9 is a mechanism that mainly has a display function (specifically, a display unit 91) for drawing information and data, and a communication function for sending and receiving information and data with external devices via at least one of wired and wireless connections, and is, for example, a mobile information terminal (PDA: Personal Digital Assistant) such as a tablet computer or a smartphone.

[0030] The worker installing the speed measuring device 8 checks the condition of the equipment 84 to be adjusted displayed on the display 91 of the mobile information terminal 9, and adjusts the installation position of the tripod 7 on which the detection unit 81 and the photographing unit 82 are mounted, and the rotation angle and elevation angle of the pan head 71 to adjust the installation state of the speed measuring device 8, such as its position and attitude, and makes various settings related to the operation of the detection unit 81 and the photographing unit 82.

[0031] The display unit 91 is composed of, for example, a liquid crystal display or an organic EL (short for Electro Luminescence) display on which a touch panel that accepts touch operations is stacked, and displays the status of the detection unit 81 and the photographing unit 82 and images captured by the photographing unit 82 (specifically, the imaging means).

[0032] Here, the speed measuring device 8 is an equipment that uses a mobile information terminal 9 to adjust the installation state such as position and posture, and to perform various settings related to operation, and below, the detection unit 81 and the photographing unit 82 are collectively referred to as the "equipment to be adjusted 84."

[0033] The portable information terminal 9 is held by the terminal holder 1 and is detachably attached to the device 84 to be adjusted (specifically, the photographing unit 82).

[0034] (Terminal holder) 2 to 11 are diagrams showing the structure and usage state of the terminal holder 1 according to the embodiment.

[0035] The terminal holder 1 in this embodiment has a holding section 2 that holds a portable information terminal 9 equipped with a display section 91 that is used for adjusting and setting the adjustment target device 84 when the adjustment target device 84 is installed, allowing it to be inserted and removed freely, an insertion / removal section 3 that is inserted into and removed from a receiving section 6 provided on the adjustment target device 84 side, and a rotating connecting section 5 interposed between the holding section 2 and the insertion / removal section 3.

[0036] The holding portion 2 is a structure for holding the mobile information terminal 9, and includes a back plate 21, side end holding portions 22, and a bottom end holding portion 23. The holding portion 2 is formed from, for example, metal or hard synthetic resin.

[0037] The side edge holding portions 22 are provided as a pair of grooves facing each other in the left-right direction. Specifically, the side edge holding portions 22 are provided behind the lower portion of the back panel 21 as a pair of grooves that are connected to both ends of the back panel 21 in the left-right direction, face each other in the left-right direction together with both end portions of the back panel 21 in the left-right direction, and open inward (and also upward).

[0038] The lower end holding portion 23 is provided as a groove that is connected to the lower end of the back plate 21 behind the lower end of the back plate 21 and opens upward together with the lower end portion of the back plate 21.

[0039] The holding portion 2 holds both side end portions and the bottom end portion of the mobile information terminal 9 by means of a pair of left and right side end holding portions 22 and a bottom end holding portion 23 so that the mobile information terminal 9 can be inserted and removed freely.

[0040] The insertion / removal part 3, lock pin 4, and rotational connecting part 5 are interposed between the holding part 2 and the adjustment target device 84 (specifically, the photographing part 82) and are structured to detachably attach the terminal holder 1 to the adjustment target device 84. The insertion / removal part 3 and lock pin 4 are formed from, for example, metal or hard synthetic resin. To prevent the lock pin 4 from being lost, the lock pin 4 is attached to the insertion / removal part 3 via a string member 41.

[0041] The insertion / removal section 3 has a bank section 31 formed as a convex section whose longitudinal direction is along a direction perpendicular to the left-right direction at each of both left-right end sections. The bank section 31 has a pin hole 32 whose side end face is open and into which the lock pin 4 can enter along the left-right direction.

[0042] A receiving portion 6 into which the insertion / removal portion 3 of the terminal holder 1 is inserted and removed is provided on the underside of the housing of the adjustment target device 84. The receiving portion 6 is provided so that its rear end surface is open and forms a storage space 61 into which the insertion / removal portion 3 can enter along the front-to-rear direction.

[0043] A coupling structure for coupling the receiving part 6 with the pan head 71 of the tripod 7 is provided on the underside of the receiving part 6. The receiving part 6 and the pan head 71 are detachably coupled together by, for example, a slide fitting structure.

[0044] In this case, a slider 85, with the front-to-rear direction as the sliding engagement direction, is disposed on the underside of the receiving portion 6, and a slide base that holds the slider 85 so that it can be inserted and removed in the front-to-rear direction is disposed on the upper surface of the pan head 71. The slider 85 on the receiving portion 6 side is inserted into the slide base on the pan head 71 side along the front-to-rear direction, thereby attaching the adjustment target device 84 to the pan head 71 of the tripod 7. Reference numeral 86 in the figure denotes an introduction plate (in other words, a guide plate) used when inserting the slider 85 on the receiving portion 6 side into the slide base on the pan head 71 side.

[0045] It is preferable that the outer dimensions of the insertion / removal portion 3 and the dimensions of the storage space 61 of the receiving portion 6 are adjusted relative to each other so that there is little or no rattling when the insertion / removal portion 3 is inserted into the storage space 61 of the receiving portion 6; specifically, it is preferable that the dimensions are adjusted so that the outer surface of the insertion / removal portion 3 slides against the inner surface of the receiving portion 6.

[0046] A through-hole 63 is formed in a side wall 62 that forms the accommodation space 61 of the receiving portion 6, penetrating in the left-right direction and allowing the lock pin 4 to pass through.

[0047] The pivotal connecting part 5 is provided between the front surface of the back plate 21 of the holding part 2 and the insertion / removal part 3, and is a structure for adjusting the angle of the holding part 2 relative to the insertion / removal part 3, relative to the receiving part 6 into which the insertion / removal part 3 is inserted, and ultimately relative to the adjustment target device 84 in which the receiving part 6 is provided. As the pivotal connecting part 5, for example, a torque hinge is used.

[0048] The pivotal connecting portion 5 adjusts the angle between the holding portion 2 and the insertion / removal portion 3 between a positional relationship in which the surface of the back plate 21 of the holding portion 2 and the surface of the insertion / removal portion 3 are perpendicular to each other (FIGS. 2, 3, etc.) and a positional relationship in which the surface of the back plate 21 of the holding portion 2 and the surface of the insertion / removal portion 3 are parallel to each other (FIGS. 4 and 5). This allows the insertion / removal portion 3 to be inserted into the receiving portion 6 of the device to be adjusted 84 with the holding portion 2 and the insertion / removal portion 3 open to each other, and allows the terminal holder 1 to be attached to the device to be adjusted 84, and when the terminal holder 1 is removed from the device to be adjusted 84 and carried, the holding portion 2 and the insertion / removal portion 3 can be closed to each other (in other words, the insertion / removal portion 3 can be folded) to make it compact.

[0049] (Use of terminal holder) The terminal holder 1 is used by being attached to an adjustment target device 84 (specifically, an imaging unit 82 constituting the adjustment target device 84) that is attached to a pan head 71 of a tripod 7 that is installed on a roadside or the like.

[0050] Specifically, first, with the holding portion 2 and the insertion / removal portion 3 of the terminal holder 1 being open from each other, the insertion / removal portion 3 is inserted into the receiving portion 6 of the device to be adjusted 84 (see FIGS. 6 to 10; note that the lock pin 4 and string member 41 are not shown in FIG. 7, and the tripod 7 is not shown in FIGS. 7 and 8). Then, the lock pin 4 is inserted from the through-hole 63 in the side wall 62 of the receiving portion 6, passes through the through-hole 63, and is inserted into the pin hole 32 of the insertion / removal portion 3 (see, for example, FIG. 8). As a result, the lock pin 4 acts as a support, and the insertion / removal portion 3 is locked so as not to come off from the receiving portion 6 while the mobile information terminal 9 held by the holding portion 2 of the terminal holder 1 is in use, thereby preventing the terminal holder 1 and the mobile information terminal 9 from falling off.

[0051] Next, the mobile information terminal 9 is inserted into the holding portion 2 of the terminal holder 1 attached to the device 84 to be adjusted (see FIG. 11). If necessary, the angle of the holding portion 2 relative to the insertion / removal portion 3 is adjusted via the pivoting connector 5 so that, for example, the display unit 91 of the mobile information terminal 9 is at an angle that is easy to view. If, for example, a torque hinge is used as the pivoting connector 5, the angle of the holding portion 2 after adjustment is maintained, and the display unit 91 of the mobile information terminal 9 is maintained in an easy-to-view state.

[0052] Then, while checking the condition of the device 84 to be adjusted displayed on the display unit 91 of the mobile information terminal 9, the user uses both hands to adjust the installation state of the device 84 to be adjusted, such as the position (specifically, the installation position of the tripod 7) and attitude (specifically, the rotation angle and elevation angle of the pan head 71), and to set various operations. If the display unit 91 of the mobile information terminal 9 is configured as a touch panel display, the user touches the display unit 91 to set various operations.

[0053] After adjustment of the installation state, such as the position and attitude, of the device 84 to be adjusted, and various settings related to its operation are completed, the mobile information terminal 9 is removed from the holding portion 2 of the terminal holder 1, and the terminal holder 1 is removed from the receiving portion 6 of the device 84 to be adjusted. Then, operation of the device 84 to be adjusted begins. Note that although the mobile information terminal 9 is not used for normal operation after adjustment and setting of the device 84 to be adjusted are completed, if readjustment or setting is required or if the status of the device 84 to be adjusted needs to be checked, the terminal holder 1 is reattached to the device 84 to be adjusted, and the mobile information terminal 9 is inserted into the holding portion 2 of the terminal holder 1 to check the condition of the device 84 to be adjusted, as displayed on the display portion 91, or an administrator or the like in a location remote from the device 84 to communicate with the device 84 to be adjusted wirelessly or the like using the mobile information terminal 9 to check the condition of the device 84 to be adjusted, as displayed on the display portion 91.

[0054] According to the terminal holder 1 of the embodiment, the mobile information terminal 9 can be detachably attached to the adjustment target device 84, and it becomes possible to use both hands to adjust (especially fine-tune) the installation state such as the position and attitude while checking the condition of the adjustment target device 84 displayed on the display unit 91 of the mobile information terminal 9, and it also becomes possible to eliminate the waste of providing a display unit for each adjustment target device 84. Furthermore, according to the terminal holder 1 of the embodiment, the structure is simple, and therefore the usage procedure is simple and handling is easy, and breakdowns are unlikely to occur even when used in an outdoor environment, which in turn makes it possible to improve versatility.

[0055] According to the terminal holder 1 of the embodiment, since it has a lock pin 4, the lock pin 4 acts as a support and locks the insertion / removal part 3 so that it does not come out of the receiving part 6 while the mobile information terminal 9 held in the holding part 2 of the terminal holder 1 is in use, making it possible to prevent the terminal holder 1 and the mobile information terminal 9 from falling off.

[0056] According to the terminal holder 1 of the embodiment, when the rotational connecting portion 5 is a torque hinge, the angle of the holding portion 2 can be maintained after being adjusted so that the display unit 91 of the portable information terminal 9 is at an angle that is easy to see, and the display unit 91 of the portable information terminal 9 can be maintained in an easy-to-see state.

[0057] According to the terminal holder 1 of the embodiment, the device to be adjusted 84 is attached to the pan head 71 of the tripod 7, so that it is possible to adjust the position of the device to be adjusted 84 by adjusting the installation position of the tripod 7 using both hands, and to adjust the attitude of the device to be adjusted 84 by adjusting the rotation angle and elevation angle of the pan head 71.

[0058] According to the terminal holder 1 of the embodiment, the device to be adjusted 84 is the speed measurement device 8, so that the above-mentioned advantageous effects can be achieved when the speed measurement device 8 is installed.

[0059] The above describes an embodiment of the present invention, but the specific configuration is not limited to the above embodiment, and even if there are design changes within the scope of the present invention that do not deviate from the gist of the present invention, they are included in the present invention.

[0060] For example, in the above embodiment, the terminal holder 1 of the present invention is attached to a speed measuring device 8 for use, but the devices to which the terminal holder 1 of the present invention can be attached are not limited to speed measuring devices 8, and the terminal holder 1 of the present invention can be attached to and used in various devices used in combination with a mobile information terminal (especially devices in which the installation state such as position and posture is adjusted and various settings related to operation are made while checking the condition of the device displayed on the display unit of the mobile information terminal).
