In addition, a pair of bracket portions 14 and 14 are formed at both ends of the grip body 1 so as to protrude laterally from the end face. The bracket portion 14 is formed in a plate shape whose plate surface is substantially parallel to the side surface 13 of the grip body 1, and an interval is formed between the bracket portion 14 and the other bracket portion 14 in the width direction of the grip body 1. A through hole 15 serving as a second bearing portion 25 is formed at the protruding end of the pair of bracket portions 14, 14.

  Further, in this example, the base 20 includes a main body portion 201 provided with the first shaft 22 and attachment legs 202 to the mounting target P protruding from the back surface of the main body portion 201. The main body 201 has a pair of side plates 201 a and 201 a in which plate surfaces are arranged in a direction substantially along a virtual straight line x including the center line of the grip body 1. The first shaft 22 is provided between the pair of side plates 201a and 201a in a bridging manner. In this example, the mounting leg 202 is fitted into the mounting hole Pb of the mounting target P configured in a panel shape to a position where the back surface of the main body 201 abuts against the outer surface Pa of the mounting target P. The engaging claw 202b of the provided metal clip 202a is engaged with the hole edge portion of the attachment hole Pb inside the attachment target P, and the base 20 is attached to the attachment target P.

On one end side of the cover-like portion 211, through holes 211c are formed in the pair of side plates 211b and 211b through the end portions of the second shaft 24, respectively. Further, in this example, the guide bearing portion 26 is connected to the inner surface of the front plate 211a of the cover-like portion 211 with one end integrally connected to the inner surface of the cover plate 211 on the side opposite to the formation side of the through hole 211c. It is configured by providing a plate piece 211d extending toward the through hole 211c with an interval substantially equal to the diameter of the single shaft 22 provided. Between the inner surfaces of the pair of side plates 211b and 211b of the cover-like portion 211, the main body portion 201 of the base 20 is housed, and the pair of bracket portions 14 of the grip body 1 are housed, and the plate piece 211d is a pair of the base 20 The first shaft 22 that fits between the side plates 201a and 201a and spans between the pair of side plates 201a and 201a fits between the plate piece 211d and the inner surface of the cover-like portion 211 in a substantially dense manner. Yes.

In this example, the second shaft 24 is arranged on the inner side of the first shaft 22 in both the pair of attachment portions 2 and 2, and the guide bearing portion 26 has the grip body 1 in the down position. The first shaft 22 is located at the inner end 261 (the end of the guide bearing portion 26 facing the grip body 1),
When the grip body 1 is in the raised position, the first shaft 22 is positioned at the outer end 262 of the guide bearing portion 26.

  In this example, the inner ends 261 of the guide bearing portions 26 are open, but the first shafts 22 and 22 are located at a lower position than the distance between the inner ends 261 of the guide bearing portions 26 of the pair of attachment portions 2 and 2. The joint 21 does not come off from the base 20 because the interval between them is large.

  In this example, the grip body 1 moves substantially in parallel between the lying position and the raised position. That is, the second shaft 24 is positioned on an imaginary straight line y that is perpendicular to the center line of the grip body 1 regardless of whether the grip body 1 is in the lying position or the raised position. The guide bearing portion 26 supports the first shaft 22 so as to be slidable so that the second shaft 24 is always positioned on the virtual straight line y.

In addition, the spring winding portion 272 of the torsion coil spring 271 is passed through the second shaft 24, and an urging force in a direction to widen the distance between both ends of the spring 271 at the raised position is stored in the spring winding portion 272. As shown, one end of the spring 271 is fixed to the cover-like portion 211 and the other end of the spring is fixed to the bracket portion 14. Thus, in this example, when the grip body 1 in the raised position is released, the assembly side by the second shaft 24 is attached to the joints 21 constituting the attachment portions 2 at both ends of the grip body 1 respectively. A force in a direction approaching the outer surface Pa of P is applied, and the joint 21 is rotated while moving the first shaft 22 to the inner end 261 of the guide bearing portion 26, whereby the grip body 1 is forcibly moved to the lying position. It has come to be. That is, in this example, the spring 271 functions as the urging means 27.

  Further, in this example, the assist grip device has the damper tool 3, and the urging movement from the raising position by the spring 271 toward the lying position is made slow.

  In this example, the damper tool 3 is formed by combining the outer cylindrical body 30 and the inner cylindrical body 31 so that the inner cylindrical body 31 rotates or relatively rotates within the outer cylindrical body 30. A resistance is imparted to the rotation by a viscous fluid sealed between the cylindrical bodies 30 and 31.

  In this example, the outer cylinder 30 in the damper tool 3 is fixed to either one of the joint 21 and the end 11 of the grip body 1, and the inner cylinder 31 in the damper tool 3 is fixed to the other of these. It is fixed to the side. In this example, the combination convex portion 30a is formed on the outer peripheral portion of the outer cylindrical body 30, and the concave portion 16 into which the convex portion 30a fits is formed between the pair of bracket portions 14 of the grip body 1. The outer cylinder 30 and the grip body 1 are integrated by fitting the convex portion 30 a of the damper tool 3 accommodated between the pair of bracket portions 14 into the concave portion 16. Further, in this example, the second shaft 24 is passed through the inner cylindrical body 31 and is fitted to the inner cylindrical body 31, and the second shaft 24 is fixed to the joint 21. Thus, the inner cylindrical body 31 and the joint 21 are integrated.

  In the example shown in FIGS. 4 to 6, each of the attachment portions 2 provided on both ends of the grip body 1 is composed of a base 20 and a joint 21, and the grip body 1 and the joint 21 Are combined through a guide bearing portion 26.

(The surface in a back-to-back position with the back surface 10) and both side surfaces 13, 13 (the surface extending between the back surface 10 and the front surface 12). At both ends of the grip body 1, through holes 17 that are opened on both side surfaces 13 and 13 are formed, and the second shaft 24 is fitted into the through holes 17.

  In this example, the base 20 has a base 203 having a long plate shape in a direction along a virtual straight line x including the center line of the grip body 1, and both side edges along the length direction of the base 203. A pair of side plates 204, 204 projecting forward from the base portion 203 is provided. The first shaft 22 has a first bearing portion 23 having a through-hole shape formed in the pair of side plates 204 and 204, respectively, and is provided so as to be able to rotate between the pair of side plates 204 and 204. . Both end portions of the first shaft 22 protrude from the outer surface of the side plate 204 to the side, and are inserted into and fitted in through holes 214 of the joint 21 described later. Further, in this example, the base 20 is attached to the mounting target P by a known technique such as screwing in a state where the back surface of the base portion 203 applied to the outer surface Pa of the mounting target P configured in a panel shape is in contact. It has become.

  In this example, the joint 21 is configured to have a cover shape having a front plate 212 and a side plate 213 along a virtual straight line x including the center line. On one end side of the joint 21, a pair of side plates 213 and 213 are formed with through holes 214 through which the first shaft 22 is fitted. The other end of the joint 21 positioned on the inner side of the first bearing portion 23 is provided with a groove width substantially equal to the diameter of the second shaft 24 in each of the pair of side plates 213 and 213, and the second shaft 24 passes therethrough. A through hole 215 having a long groove shape as a guide bearing portion 26 is formed. The pair of side plates 204 and 204 of the base 20 are accommodated between the inner surfaces of the pair of side plates 213 and 213 of the joint 21 and the end portion 11 of the grip body 1 is accommodated. The end of the second shaft 24 that is fastened is received in the through hole 215 having the long groove shape.

In this example, the second shaft 24 is disposed on the inner side of the first shaft 22 in both of the pair of attachment portions 2 and 2, and when the grip body 1 is in the raised position, in the guide bearing portion 26. The second shaft 24 is positioned at the inner end 261 (the end of the guide bearing portion 26 facing the grip body 1),
When the grip body 1 is in the down position, the second shaft 24 is positioned at the outer end 262 of the guide bearing portion 26.

  Even in this example, the grip body 1 is configured to move substantially in parallel between the lying position and the raised position. That is, the first shaft 22 is positioned on an imaginary straight line y that is perpendicular to the center line of the grip body 1 regardless of whether the grip body 1 is in the lying position or the raised position. The guide bearing portion 26 supports the second shaft 24 so as to be slidable so that the first shaft 22 is always positioned on the virtual straight line y.

  In this example, the torsion coil spring 271 is disposed between one inner surface of the pair of side plates 213 and 213 constituting the joint 21 and one inner surface of the pair of side plates 204 and 204 constituting the base 20. The spring winding portion 272 is passed through the first shaft 22, and the urging force in a direction to narrow the interval between the spring ends of the spring 271 at the raising position is stored in the spring winding portion 272. One end of the spring 271 is fixed to the joint 21, and the other end of the spring is fixed to the base 20. Thus, in this example, when the grip body 1 in the raised position is released, the assembly side by the second shaft 24 is attached to the joints 21 constituting the attachment portions 2 at both ends of the grip body 1 respectively. A force in a direction approaching the outer surface Pa of P is applied, and the joint 21 is rotated while moving the second shaft 24 to the inner end 261 of the guide bearing portion 26, whereby the grip body 1 is forcibly moved to the lying position. It has come to be. That is, in this example, the spring 271 functions as the urging means 27.

  Further, in this example, the assist grip device has the damper tool 3, and the urging movement from the raising position by the spring 271 toward the lying position is made slow.

  The damper tool 3 of this example has substantially the same configuration as the damper tool 3 of the example shown in FIGS. In this example, the outer cylinder 30 is fixed to the base 20, and the first shaft 22 fixed to the joint 21 is passed through the inner cylinder 31 so that the outer cylinder 30 is fitted to the inner cylinder 31. It has become.

  Further, in this example, the base 20 includes a shaft hole 206 a for receiving the rotation shaft 217 of the joint 21, a main body portion 206 having the guide portion 205, and a fixing portion 207 to the mounting target P. .

  The guide portion 205 is formed on the inner side of the main body portion 206, that is, on the side facing the center side of the grip body 1. The guide 205 closes the groove end on the outer surface Pa side of the mounting target P, opens the groove end opposite to the groove end, and opens the side directed toward the center side of the grip body 1. The groove width of the guide portion 205 (the dimension between the pair of side walls 205a and 205a) is substantially equal to the dimension between the outer surfaces of both sides where the window hole 18a of the slider portion 18 is formed.

  The outer portion of the main portion 206 is formed in a block shape, and the outer portion is provided with the shaft hole 206a in which the hole shaft is positioned in a direction substantially parallel to the outer surface Pa of the mounting target P. A part of the shaft hole 206a is constituted by the outer cylindrical body 30 of the damper tool 3 fitted in the outer portion. That is, in this example, the outer cylinder body 30 and the inner cylinder body 31 are combined so that the inner cylinder body 31 rotates or relatively rotates within the outer cylinder body 30, and both cylinder bodies 30 are subjected to this rotation. , 31 is provided with a damper tool 3 configured to give resistance by a viscous fluid sealed between the outer cylinder body 31 and the cylinder axis of the outer cylinder body 30 of the outer cylinder body 30 of the damper tool 3. It is fitted and fixed to the outer portion of the base 20 so as to be substantially parallel to the outer surface Pa. In this example, the rotation shaft 217 of the joint 21 is fixed to the joint 21 and is passed through the inner cylindrical body 31 of the damper tool 3 and is fitted thereto.

  The damper tool 3 of this example also has substantially the same configuration as the damper tool 3 of the example shown in FIGS.

  Specifically, the fitting space 206b of the damper tool 3 is an outer portion of the main body portion 206, and sandwiches a position in the middle of the width direction (direction perpendicular to the length direction of the grip body 1). Formed on the side. In addition, a circumferential groove 206c around the shaft hole 206a is formed on a side opposite to the formation side of the fitting space 206b in the outer portion, and a torsion coil spring as an urging means 27 described later is formed in the circumferential groove 206c. 273 is stored. The torsion coil spring 273 has one end fixed to the base 20 and the other end fixed to the joint 21. When the joint 21 is moved from the reference position toward the maximum rotation position, the joint 21 The urging force in the direction of pushing back the joint 21 toward the reference position is applied.

  The back surface 10 side of the main body portion 206 functions as the fixing portion 207. In this example, the mounting portion 2 includes a through-hole 207a of a bolt N formed in a board portion that closes the groove end of the guide portion 205, and a positioning shaft 207b that protrudes from the back surface 10 of the main portion 206 at the side of the through-hole 207a. It consists of and. When the positioning shaft 207b is inserted into the insertion hole of the positioning shaft 207b formed in the mounting target P, the base 20 is mounted by screwing the bolt N into the screw hole of the mounting target P through the through hole 207a. Attached to P.

  Further, in this example, the joint 21 includes a front plate 218a, a pair of side plates 218b, 218b, and a groove having a substantially U-shaped cross section formed by the front plate 218a and the pair of side plates 218b, 218b. And an end plate 218c that closes one end. The rotation shaft 217 is provided so as to extend between the inner surfaces of the pair of side plates 218b and 218b on the side closed by the end plate 218c. In this example, the main body portion 206 of the base 20 is accommodated inside the joint 21, and the joint 21 is rotatable to the base 20 by the rotation shaft 217 passed through the shaft hole 206 a of the main body portion 206. Are combined.

  The joint 21 has a gripper body 1 in which the slider portion 18 is inserted into the guide portion 205 of the base 20 at a reference position where the front plate 218a is positioned substantially parallel to the outer surface Pa of the mounting target P. The slider portion 18 is configured to be covered from the front by the front plate 218a. (Fig. 7)

  Further, the abutting portion 216 to the end portion 11 of the grip body 1 is formed on the side opposite to the closing side by the end plate 218c of the joint 21. In this example, the abutting portion 216 is configured to contact the slider portion 18 of the grip body 1 from the front. Since the joint 21 is always biased toward the reference position by the spring 273 as the biasing means, the abutting portion 216 of the joint 21 is always pressed against the end portion 11 of the grip body 1, and the grip body 1 is The grip body 1 is stably positioned at the prone position, and after the grip body 1 is moved to the raised position, when the operation is stopped, the grip body 1 is again pulled back to the prone position by the joint 21 rotated back to the reference position.

  The state where the grip body 1 is in the raised position is maintained by restricting the rotation of the joint 21 beyond the maximum rotation position. In this example, the distance between the ends of the abutting portions 216 of the joint 21 constituting the attachment portion 2 of the pair of grip bodies 1 is shorter than the entire length of the grip body 1 at the maximum rotation position of the joint 21. In addition, the distance between the abutting portion 216 at the maximum rotation position and the front surface of the main portion 206 of the base 20 where the open groove end of the guide portion 205 is located is a slider in the moving direction of the grip body 1. The thickness dimension of the portion 18 is smaller. As a result, the grip body 1 raised to the position where the joint 21 is positioned at the maximum rotation position cannot be further removed from the mounting target P.

  In this example, the side plate of the joint 21 connected to the end plate 218c is inclined so as to gradually move away from the outer surface Pa of the mounting target P toward the end plate 218c when the joint 21 is at the reference position. The formed edge 218d is formed, and the rotation of the joint 21 beyond the position where the edge 218d hits the outer surface Pa of the mounting target P is restricted. (Fig. 8)

  Further, the abutting portion 216 of the joint 21 has a surface 216a substantially parallel to the edge portion 218d. When the grip body 1 is in the down position and the joint 21 is in the reference position, the abutting portion 216 is provided. Only the front end 216b of the slider contacts the slider portion 18 from the front. When the grip body 1 is in the raised position and the joint 21 is in the maximum rotation position, the surface 216a of the abutting portion 216 is substantially parallel to the outer surface Pa of the mounting target P, and the slider portion 18 from the front. It is pressed face down.

  Further, in this example, the pin 219 extending between the pair of side plates 218 b and 218 b of the joint 21 is passed through the window hole 18 a of the slider portion 18 of the grip body 1 so that the grip body 1 and the base 20 are connected via the joint 21. Are combined. When the grip body 1 is in the down position, the pin 219 is positioned at the front corner inside the window hole 18a (center side of the grip body 1) without touching the inner wall of the window hole 18a (FIG. 7). When 1 is in the raised position, the pin 219 is positioned at the outer rear corner of the window hole 18a so as not to contact the inner wall of the window hole 18a. (FIG. 8) The pin 219 is composed of, for example, a metal rod-like body having a required rigidity. When an excessive load is applied to the grip body 1 and the abutting portion 216 is bent, the window hole 18a This load is received in contact with the inner wall, thereby preventing the butt portion 216 from being damaged in such a case.

  Even in this example, since the assist grip device has the damper tool 3, the urging movement from the raised position to the lying position by the spring 273 is made slow.
