Description

  The present invention relates to a support that can support an apparatus in a desired posture or height, a support structure for the apparatus, and components used therefor.

  A device using a Doppler sensor is known as a velocity measuring device that measures the maximum velocity of a moving measuring object. In this method, a microwave is applied to an object that is a non-measurement object, and a reflected wave from the object is measured. When the object is moving with respect to the traveling direction of the microwave, the frequency of the reflected wave changes due to the Doppler effect, so the speed of the object can be calculated by comparing this with the frequency of the emitted wave. it can. A conventional speed measuring device using this type of Doppler sensor is generally used to measure the speed (ball speed) of a ball thrown by a pitcher in baseball. In addition, the measurement object in the speed measuring device using the Doppler sensor is not limited to the object that performs a decelerating movement such as the ball speed, and the object that is moving at a constant speed such as the traveling speed of an automobile, There are various types such as a swinging motion of a golf club or the like that accelerates rapidly from a state of zero speed and performs an accelerating motion to reach the highest speed at the point of hitting the ball.

  As a speed measuring device for measuring the swing speed or the like of a golf club, for example, there is one disclosed in Patent Document 1. In the apparatus disclosed in Patent Document 1, the case body is a flat, rectangular parallelepiped rectangular box. And when actually measuring speed, this apparatus is installed in the back predetermined position of the golfer who swings a golf club. The specific installation position is such that the detection range of this apparatus includes a point where the golf club head during the swing moves at the maximum speed. Usually, the vicinity of the lowest point of the golf club head movement locus is the impact position on the ball, and normally the movement speed of the head is the maximum speed in the vicinity of the position. And the position behind the golfer is the installation position. Further, as described above, in golf, since the ball on the ground (or on a tee up tee) is hit, the maximum speed in the golf swing is near the ground. It is placed directly on the ground.

The outer diameter of the base portion 22a substantially matches the inner diameter of the peripheral wall portion 21e. Further, with the base portion 22a disposed in the peripheral wall portion 21e, a female screw 22d is provided at a position corresponding to the through hole 21f, and a hole portion 22e is provided at a position corresponding to the positioning protrusion 21g. The height (thickness) of the base portion 22a is equal to or lower than the height of the peripheral wall portion 21e (in the embodiment, it is set low).

  Thereby, first, the base 22a is inserted and disposed in the peripheral wall 21e with the positioning convex portion 21g of the base member 21 and the hole 22e of the ball component 22 (base 22a) facing each other. Then, since the through hole 21f of the base member 21 and the female screw 22d provided in the base portion 22a face each other, the fixing screw 23 is inserted into the through hole 21f from the upper surface side of the base member 21 and fastened to the female screw 22d. The ball component 22 and the base member 21 are connected and integrated.

  Further, since the height (thickness) of the base portion 22a is equal to or lower than the height of the peripheral wall portion 21e, the base portion 22a is in the peripheral wall portion 21e when the ball component 22 and the base member 21 are connected.

  As shown in FIG. 8, small circular openings 12d are formed at two positions on the bottom surface of the case main body 10 (lower case 12) of the speed measuring device 1, as shown in FIGS. A cylindrical portion 12f is formed on the upper surface side of the lower case 12 so as to be linked to the opening 12d. A cylindrical protrusion 21a provided on the base member 21 is inserted into an opening 12d provided on the case body 10, and is fitted and fixed in the cylindrical portion 12f. This fixing may utilize a frictional force generated between the outer peripheral surface of the protrusion 21a and the inner peripheral surface of the cylindrical portion 12f, or may be mechanically connected.

  Furthermore, circular ridges 12e and 12e 'are formed at predetermined positions on the bottom surface of the lower case 12 constituting the case body 10. The protrusions 12e and 12e ′ are arranged at the vertices of a virtual rectangle, and the two protrusions 12e on the front side of the case body 10 are provided in the vicinity of the rear of the opening 12d, and the rear side of the case body 10 The two convex shapes 12e ′ are provided on the battery lid 16 in the vicinity of the rear end. The four convex shapes 12e and 12e 'serve as feet when the speed measuring device 1 is directly placed on the ground or the like, and the entire bottom surface of the lower case 11 is grounded or the like by floating by the height of the convex shapes 12e and 12e'. It is possible to avoid contamination due to surface contact.

Is provided. The inner diameter of the first circular rib 21b is equal to or larger than the outer diameter of the convex shape 12e, and the height of the first circular rib 21b is set higher than the height of the convex shape 12e. Thus, in a state where the base member 21 is mounted on the case main body 10 (lower case 12), the protrusion 12e enters the first circular rib 21b, and the protrusion 21e is hidden by the base member 21.

  Further, when the inner diameter of the first circular rib 21b and the outer diameter of the convex shape 12e are set to be equal, the connection between the two sets of projections 21a and the cylindrical portion 12f, and the two sets of first circular ribs 21b and the convex shape. It will be linked at four points of the 12e coupling, and will be held more firmly and will also prevent rotation.

  Further, as shown in FIG. 9, the lateral width of the base member 21 is set to be almost as wide as the lateral width of the flat portion of the bottom surface of the lower case 12 so that the entire surface can be stably linked and supported.

  As shown in FIG. 10, the cylindrical portion 12f provided in the lower case 12 has a screw 18 attached to the upper end from the inside, and the tip of the screw 18 protrudes to the outside of the cylindrical portion 12f. The tip of the screw 18 passes through the positioning hole 19 a provided in the circuit board 19. Further, the upper end surface of the cylindrical portion 12 f is in contact with the lower surface of the circuit board 19 and supports the circuit board 19. Thereby, the circuit board 19 is set at a desired position. Further, as shown in FIG. 11, the screw 18 is fastened to a female screw provided at the lower end of a column 11 e formed to extend downward to a predetermined position on the top surface of the upper case 11. That is, the screw 18 is a screw for connecting and fixing the case 12 as the upper case 11, and the cylindrical portion 12f originally receives the circuit board 19, and the screw 18 is inserted from the bottom surface side of the lower case 12, This is for the screw head of the screw 18 to come into contact with the top surface of the upper end of the cylindrical portion 12f and stop, and can be said to be a screw hole. In order to insert the screw 18 in this way, the lower end of the cylindrical portion 12f is opened by the opening 12d. So in this embodiment. By adopting a configuration in which the protrusion 21a of the base member 21 is inserted into the cylindrical portion 12f that is a screw hole for fixing a plurality of such members, the number of holes provided in the case main body 10 can be reduced, and it looks good. Becomes resistant to dirt such as mud.

  Further, the ball part 22c of the ball component 22 is provided with a female screw part 22h for a tripod screw as shown in FIG. The shaft center of the female screw portion 22h for the tripod screw and the shaft center of the neck portion 22b are set so as to be in the same straight line. Furthermore, the opening side of the female screw portion 22h for the tripod screw takes a form that is cut off in a plane orthogonal to the axis of the female screw portion 22h for the tripod screw, and a tripod attachment portion 22j that is formed by a ring-shaped plane having a predetermined width. It has.

  As shown in FIG. 12 to FIG. 16 and the like, the bracket base (pedestal) 3 includes a thick portion 32 that swells upward in the center of the upper surface of the flat plate-shaped substrate portion 31, and a spherical surface near the top surface of the thick portion 32. The structure which provided the shape-shaped recessed part 33 is taken. The bracket base 3 is made of a material that can be elastically deformed such as rubber and has an appropriate coefficient of friction.

  The outer diameter of the ball portion 22c and the inner diameter of the recess 33 are set to be approximately equal. The concave portion 33 has a shape in which the upper portion of the spherical surface is opened, and the opening diameter of the upper portion is smaller than the inner diameter of the concave portion 33 and is hemisphere or more. Accordingly, as shown in FIG. 16 and the like, in a state where the ball portion 22c enters the recess 33, the outer shape of the ball portion 22c and the inner shape of the recess 33 substantially coincide with each other, and the ball portion 22c extends along the spherical surface. It can be rotated and moved in any direction. And while making both diameters substantially correspond and giving an appropriate friction coefficient to the inner shape of the recess 33, the ball portion 22c and thus the joint base 2 can be held at an arbitrary angle and posture.

  Furthermore, since the bracket base 3 can be elastically deformed, if the joint base 2 is urged upward while holding the bracket base 3 from the state shown in FIG. 16 or the like, the diameter of the opening of the recess 33 increases. The ball portion 22c can be detached from the recess 33. On the contrary, when the bracket base 3 and the joint base 2 are separated from each other, when the ball portion 22c is pressed against the opening of the concave portion 333 and is urged to be pushed toward the bracket base 3 in this state, the concave portion 33 is obtained. Due to the elastic deformation, the opening is once expanded and the ball portion 22 c is accommodated in the recess 33. Thereafter, the shape of the recess 33 is restored to its original shape by the elastic restoring force of the bracket base 3, and the ball portion 22 c is prevented from being easily detached from the recess 33.

  As described above, the speed measuring device 1 includes the four circular ridges 12e and 12e 'on the bottom surface thereof, so that the ridges 12e and 12e' serve as feet, and are directly placed on the ground or other places. Can be measured. And as shown in FIG. 1 etc., while attaching the joint base 2 to the bottom face of the speed measuring device 1, and connecting the joint base 2 to the bracket base 3, by placing the bracket base 3 on the ground or the like, The height position of the speed measuring device 1 can be raised from the installation position to a higher position by the height from the bottom surface of the bracket base 3 to the upper surface of the base member 21. Furthermore, since the ball joint is formed by the joint base 2 and the bracket base 3, the angle of the direction of the speed measuring device 1 can be adjusted.

  As shown in FIG. 16, a shallow bottom recess is formed on the bottom surface of the base 11. In this recess, for example, one surface of an adhesive member such as a pressure-sensitive adhesive sheet, a double-sided adhesive tape, or a hook-and-loop fastener is mounted, and the other surface of the adhesive member is attached to the installation position of the table or other speed measuring device 1. Thereby, the speed measuring device 1 can be firmly fixed to the installation position in a desired direction / posture.

  Further, when the joint base 2 attached to the speed measuring device 1 is attached to the bracket base 3, the tripod attachment portion 22j made of a flat surface provided on the ball portion 22c in the movable range of the speed measuring device 1 is set not to be exposed. When the tripod attachment portion 22j is exposed, a gap / space is formed between the upper end opening of the recess 33 and the ball portion 22c, which is not stable, and there is a possibility that mud or the like may enter from the gap, and the gap Since it looks and looks bad, adopting the above settings will prevent such a situation from occurring.

  FIG. 17 shows an example in which the speed measuring device 1 is used while being fixed to a tripod. In this usage mode, the ball portion 22c is exposed in a state where the joint base 2 is attached to the bottom surface of the speed measuring device 1. Thereby, the female screw part 22h for tripod screws and the tripod attachment part 22j provided on the ball part 22c are also exposed to the outside. Therefore, a commercially available tripod 50 is prepared, and a fixing screw 52 protruding upward from the upper surface of the pan head 51 of the tripod 50 is attached to a female screw portion 22h for a tripod screw provided on the ball portion 22c. When firmly fastened and fixed, the tripod mounting surface 22j is supported in surface contact with the upper surface of the pan head 51. Since the tripod attachment surface 22j is composed of a flat surface having a certain width, the contact area with the pan head 51 is sufficient, and the speed measuring device 1 can be attached to the tripod 50 in a stable state.

  Thereby, the function of the tripod 50 allows the speed measuring device 1 to be in a desired orientation / posture or to be positioned at a desired height. In particular, when a measurement function of the speed measuring device 1 is used to measure the bat swing in the batting mode or measure the running speed of the runner in the short distance mode, a certain amount of high is required when performing such measurement. However, it is preferable to use a tripod because it can be fixed at a desired height.

  Further, in the above-described embodiment, the upper surface of the plate-like base member 21 is in contact with the lower case 12 of the speed measuring device 1 over the entire surface (the actual surface is in contact with the upper surface of the rib) and stably supported. However, the present invention is not limited to this. For example, the base portion 22a in the ball component 22 is eliminated, and a male screw serving as a fixing portion at the end portion of the neck portion 22b (the non-connection side of the ball portion 22c). And a female screw to which the male screw is fastened may be provided at a desired position of the lower case 12 of the speed measuring device 1. In this case, when the male screw of the ball part 22 is fastened and fixed to the female screw provided on the lower case 12 of the speed measuring device 1, the ball portion 22 c is fixed to the lower side of the speed measuring device 1. .
