Description

  The present invention relates to an adjuster provided in furniture or the like, or a part suitably used as various grips.

  For example, a conventional adjuster is known which includes a screw having a head at one end of a screw shaft and a grounding body attached to the head of the screw (see Patent Document 1). . In this device, a groove is formed on the side surface of the head of the screw, and a claw provided on the grounding body is engaged with the groove while the grounding body is mounted on the head of the screw. Therefore, not only special machining to form the groove on the head of the screw is required, but also the claw needs to be placed in an internal position where it is difficult to expose to the outside. In addition, there is a problem that it is difficult to design for easily performing the operation of separating the grounding body from the screw.

  As another adjuster, a screw having a head at one end of the screw shaft and first and second grounding bodies mounted so as to sandwich the head of the screw from above and below. Is also known (see Patent Document 2). However, in this device, the first and second grounding bodies are attached to the screws by engaging the claws provided on the first grounding body with the recesses provided on the second grounding body. For this reason, it is necessary to dispose the claw at an internal position of the grounding body. Therefore, there is a problem that it is difficult to design such an adjuster so that the operation of separating the grounding body from the screw can be easily performed at the time of separation and disposal.

  In any of the adjusters described above, a force for releasing in the axial direction of the screw acts directly on the claw of the grounding body. For this reason, there are many restrictions on the shape, placement position, number of claws, etc. of the elastic claws to cope with such effects, and there is a problem that the degree of freedom of design giving priority to easy disposal is low. Yes.

  The above circumstances include a screw having a head at one end of the screw shaft, and a grip that attaches another head holding body corresponding to the grounding body to one end portion including the head of the screw. The same applies to parts, and some measures are desired.

The head portion 12 of the screw 1 has an outer dimension larger than that of the screw shaft 11, and has an end surface 12a that is a surface facing the screw shaft 11 side, and a side opposite to the opposite screw shaft side, that is, the side where the screw shaft 11 exists. An end surface 12b which is a surface facing, and a side surface 12c which is located between these end surfaces 12a and 12b and has a surface facing in a direction substantially orthogonal to the axis of the screw shaft 11 are provided.

  At one end of the screw shaft 11, that is, at the end on the head 12 side and the head 12, a hole for mounting a tool (not shown) used when mounting the adjuster B to the fixing nut N of the furniture K is more concrete. Speaking specifically, the hexagonal hole 13 is formed in this embodiment. Further, at the other end of the screw shaft 11, that is, at the end on the front end side, the adjuster B is screwed up and down with respect to the furniture K in the vertical direction to adjust the grounding state of the furniture K. More specifically, the hexagonal hole 14 is formed in this embodiment.

  The grounding body 2 is integrally formed of resin, and an insertion portion S in which one end portion including the head portion 12 of the screw 1 can be inserted from a direction intersecting the axis of the screw shaft 11 and the insertion portion S are inserted. And a retaining portion T that restricts the screw 1 from being pulled out.

  More specifically, the grounding body 2 has a first wall 21 that covers the end surface 12a on the screw shaft 11 side in the head 12 of the screw 1 and a second wall that covers the end surface 12b on the counter screw shaft side in the head 12 of the screw 1. A wall 22 and a side wall 23 provided around the side surface 12c of the head portion 12 of the screw 1 and connecting the first wall 21 to the second wall 22, and the insertion portion S is at least the first wall. 21 and a part of the side wall 23 are removed. “Removing” is a concept including removing after molding and removing a corresponding portion in advance at the time of molding.

  Specifically, the insertion portion S is provided between the first wall 21 and the second wall 22, the main insertion portion S <b> 1 receiving the head 12 of the screw 1, and the screw 1 of the screw 1 provided on the first wall 21. A sub-insertion portion S2 for receiving the shaft 11 is provided.

  The main insertion portion S1 has a width dimension slightly larger than the diameter of the head portion 12 of the screw 1, and the head portion 12 can be rotated on the back side of the inner side surface 231 of the side wall 23 constituting the main insertion portion S1. It has a semicircular arc-shaped back inner side surface 231a that restricts the movement of the inserted head 12 in the back direction. The inner side surface 231 of the side wall 23 in the main insertion portion S1 is provided in a substantially U shape in plan view as a whole. The sub insertion portion S2 has a width dimension slightly larger than the diameter of the screw shaft 11, and the screw shaft 11 can be rotated on the inner side 211 of the first wall 21 constituting the sub insertion portion S2. It has a semicircular arc-shaped inner side surface 211a that restricts the movement of the inserted screw shaft 11 in the inner direction so as to be held. In other words, the inner side surface 211 which is a cut-out surface of the first wall 21 in the sub insertion portion S2 has a substantially U shape in plan view as a whole.

  The second wall 22 has an outer surface 221 as a contact surface with respect to the floor surface F, and has a substantially disk shape in the present embodiment. The second wall 22 is formed with a tool insertion hole 222 at the center. Further, a through hole 232 is formed in a portion of the side wall 23 opposite to the entrance g side of the insertion portion S, and a tool or the like can be inserted as necessary.

  The retaining portion T is provided with a retaining claw T1 for retaining that engages with the head portion 12 of the screw 1 inserted into the insertion portion S by using temporary elastic deformation of the member. The locking claw T1 is disposed near the entrance g of the insertion portion S. More specifically, a slit SL having a substantially U shape in plan view that penetrates from the inner surface to the outer surface of the second wall 22 is formed in the vicinity of the peripheral edge of the second wall 22 of the grounding body 2, and the inside of the slit SL is formed inside the slit SL. The locking claw T1 is used to prevent the removal.

  One end of the locking claw T1 is cantilevered by the second wall 22 and can be elastically deformed downward. The locking claw T1 includes a protruding portion T11 that protrudes above the inner surface 223 of the second wall 22. At the same time, a portion connected to the second wall 22 is provided with a hinge portion T12 that is formed to be relatively thin so as to allow elastic deformation in the vertical direction of the locking claw T1. Further, on the free end side of the locking claw T1, an inner side surface T13 that engages with the side surface 12c of the head 12 of the screw 1 inserted inside is provided, and a lower protruding portion T14 that protrudes downward is provided. Yes. The lower end T15 of the locking claw T1, that is, the lower end T15 of the downward projecting portion T14 is provided so as to be substantially flush with the grounding surface 221 that is the outer surface of the second wall 22, and the grounding surface 221 contacts the floor surface F. In this state, the locking claw T1 is configured not to be elastically deformed downward.

  Furthermore, the locking claw T1 includes a guide surface T16 that is inclined so that the surface position gradually increases from the outside toward the inside on the upper surface thereof. Therefore, when the screw 1 is attached to the grounding body 2, the engaging claw T1 can be temporarily elastically deformed downward by receiving the force from the screw 1 on the guide surface T16. A meat stealing portion T17 for facilitating elastic deformation of the locking claw T is provided on the lower surface intermediate portion of the locking claw T.

  With such a configuration, the head 12 of the screw 1 is inserted into the insertion portion S of the grounding body 2 from a direction perpendicular to the axis of the screw shaft 11 with the grounding surface 221 of the grounding body 2 open. When inserted, the guide surface T16 of the locking claw T1 is pressed by the head 12 of the screw 1 to be inserted, and the locking claw T1 is elastically deformed downward. Therefore, the head 12 of the screw 1 can be inserted to the back end of the insertion portion S. When the head 12 of the screw 1 reaches the back end of the insertion portion S, the head 12 of the screw 1 passes through the locking claw T1, and the locking claw T1 is caused by its own elastic repulsive force. It returns to the projecting state having a portion projecting upward from the inner surface 223 of the second wall 22 in the initial state. As a result, the head 12 of the screw 1 is blocked by the inner surface T13 of the locking claw T1 and is prevented from coming out outward.

  The adjuster B which is a completed part is screwed into the female screw hole of the fixing nut N of the base frame K1 of the furniture K. That is, a tool (not shown) in which the screw shaft 11 of the adjuster B is inserted into the tool insertion hole 222 formed in the second wall 22 in the fixing nut N of the base frame K1 with the base frame K1 turned over. ) To temporarily install. After that, the base frame K1 is placed on the floor F in a normal posture, and the screw 1 is screwed forward and backward using the tool L mounted in the tool insertion hole 14 provided at the other end of the screw shaft 11. Adjust the grounding state of furniture K.

  In this embodiment, the screw shaft 11 can be idled with respect to the grounding body 2. In other words, the screw 1 and the grounding body 2 can be rotated relative to each other. Can be adjusted. When the adjustment of the grounding state is completed and the grounding surface 221 of the grounding body 2 is in contact with the floor surface F, the lower end T15 of the locking claw T1, that is, the lower end T15 of the lower end protruding portion T14 is engaged with the floor surface F. The pawl T1 cannot be elastically deformed downward. Therefore, if the retaining portion T is in the present embodiment, the grounding body 2 is reliably prohibited from coming off the screw 1.

  When the adjuster B thus formed is removed from the furniture K and discarded, the upper portion of the locking claw T1 is pressed downward by some means such as a tool with the grounding surface 221 of the grounding body 2 open. The screw 1 can be easily removed laterally from the insertion portion S of the grounding body 2, and the metal screw 1 and the synthetic resin grounding body 2 can be separated and discarded.

  Thus, with such an adjuster B, even if an external force in the axial direction acts between the screw 1 and the grounding body 2, the force does not directly act on the locking claw T1. Moreover, since this latching claw T1 should just be provided near the entrance g of the insertion part S of the grounding body 2, it can also be easily arrange | positioned in the position where it is easy to access from the outside. Therefore, the design for facilitating separation and disposal of the shape and arrangement position of the locking claw T1 can be made relatively easy, and the degree of design freedom is increased. In particular, in this embodiment, the grounding body 2 is arranged so that the upper surface portion of the locking claw T1 is visible, and the locking claw T is placed in a state where the grounding surface 221 is separated from the floor surface F or the like. If pressed, the grounding body 2 can be easily detached from the screw 1.

  In addition, as shown in FIG. 8, by attaching the cap C from the outside to the grounding body 2 in the adjuster B, the appearance is improved, or the screw 1 is more preferably suppressed from coming out of the grounding body 2. Will be able to do. The cap C is formed so as to substantially correspond to the space shape of the insertion portion S of the grounding body 2 in a state where the screw 1 is inserted. Incidentally, the cap C shown in FIG. 8 is separate from the grounding body 2, but is not limited thereto. For example, the cap C may be formed integrally with the grounding body 2. That is, the boundary part of a cap and a grounding body can be considered as a hinge part, and the cap can be opened and closed with respect to the grounding body using this hinge part as a fulcrum.

  As described above, the adjuster B, which is a component according to the present embodiment, has a structure in which the grounding body 2 that is the head-carrying body intersects one end portion including the head 12 of the screw 1 with the axis of the screw shaft 11. Since the insertable portion S is provided, when the screw 1 is attached to the grounding body 2, it is attached by inserting the screw 1 into the grounding body 2 from the direction intersecting the axis of the screw shaft 11. In addition, when the screw 1 is detached from the grounding body 2, the screw 1 is moved away from the grounding body 2 by moving the screw 1 with respect to the grounding body 2 in a direction intersecting the axis of the screw shaft 11. be able to.

  Since the retaining portion T that restricts the screw 1 inserted into the insertion portion S from being pulled out is provided, the screw 1 is prohibited from moving out of the grounding body 2 by moving in the direction intersecting the axis of the screw shaft 11. can do.

  Since the grounding body 2 that is a head-carrying body is integrally formed of resin, it can be relatively lightweight and excellent in strength, and can be handled with a reduced number of parts. It will be excellent.

  The grounding body 2 that is a head-carrying body includes a first wall 21 that covers the end surface 12a on the screw shaft 11 side in the head 12, and a second wall 22 that covers the end surface 12b on the anti-screw shaft side in the head 12; It is provided with a side wall 23 provided around the head 12 and connecting the first wall 21 to the second wall 22, and the insertion portion S is formed by removing at least a part of the first wall 21 and the side wall 23. Therefore, the external force in the axial direction of the screw shaft 11 can be suitably received by the first wall 21 and the second wall 22. Since the retaining portion T is provided with a retaining claw T1 for retaining that engages with the head 12 of the screw 1 inserted into the insertion portion S by using temporary elastic deformation of the member. The movement of the head 12 of the screw 1 can be restricted so that the screw 1 can be prevented from being detached from the grounding body 2.

  The parts shown in the present embodiment are used as an adjuster B with the outer surface of the second wall 22 of the grounding body 2 as a grounding surface 221 and the screw 1 screwed to a support object such as furniture K. In a state where the ground surface 221 is in contact with the floor surface F, the locking claw T1 is configured not to be elastically deformed. More specifically, the locking claw T1 is cantilevered to the second wall 22. Since the lower end T15 of the locking claw T1 is set to be substantially flush with the ground contact surface 221 of the second wall 22, the adjuster B is the floor surface F. It is possible to suitably prevent the screw 1 from being detached from the grounding body 2 in the state where the screw 1 is installed.
