Description

[Technical Field]

[0001] The present invention relates to a temporary fixing jig used for fixing equipment, and more particularly to an equipment rack mounting jig suitable for fixing transmission equipment such as relay devices and terminal devices to a rack. [Background technology]

[0002] Transmission devices and other equipment installed in business facilities are generally stacked in multiple layers on dedicated racks. Because the equipment can be arranged in a wide variety of configurations, racks do not have shelves, and the equipment to be fixed is directly fixed to the support members (support members such as angle bars). For this reason, the conventional method involves temporarily fixing the mounting rails to the support members, then placing the equipment to be fixed on the rails and fixing the support members to the equipment. However, the temporary fixing of the mounting rails is also achieved by bolting, just like the fixing of the equipment to be fixed. Therefore, the more equipment to be fixed, the longer it takes to install and remove the rails, which lengthens the construction period.

[0003] In light of this situation, jigs have been proposed, as disclosed in Patent Document 1 and Patent Document 2. The jig disclosed in Patent Document 1 is composed of a base portion arranged along the plate surface of a support member having a plurality of through holes formed at regular intervals along the longitudinal direction, an insertion portion erected on this base portion and inserted into the through holes, and a plate-like mounting portion provided parallel to the insertion portion with the base portion as a base point.

[0004] A jig with such a configuration forms a temporary mounting base for the device to be fixed by positioning the mounting portion on the upper surface and inserting the insertion portion into the through-hole of the support member. A jig with such a configuration is simple in structure and easy to attach and remove, allowing for quick work. However, the arrangement of the jig disclosed in Patent Document 1 involves simply inserting the insertion portion into the through-hole, which leaves concerns about stability and poses a high risk when mounting expensive devices.

[0005] The jig disclosed in Patent Document 2 mainly consists of a fixed bar and a movable bar, with the fixed bar having claws that engage with through holes provided in the angle bar, and the movable bar having a rotating member on its upper surface that supports the equipment to be fixed.

[0006] A jig with this configuration can achieve stable support simply by hooking the claws into the through-holes. Furthermore, after the target device is secured, the engagement of the securing bar can be released by moving the movable bar and retracting it from the bottom of the target device. However, since the jig disclosed in Patent Document 2 supports the target device at points, there is a risk of damage to the underside of the target device when supporting a heavy target device, and there is a risk that the jig will be limited in the types of devices it can support.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and to provide an equipment rack mounting jig that is easy to attach and detach, stable, and highly versatile for use with equipment. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the equipment rack mounting jig of the present invention is a jig used when mounting a target device on an equipment mounting rack composed of support members having a plate surface with a plurality of through holes formed at regular intervals along the longitudinal direction, and is characterized in that it has a pair of clamping pieces which have a clamping surface for clamping the support members and which form a mounting surface on which the target device is temporarily placed in a position that becomes the upper surface when the support members are clamped, a fixing means for maintaining the clamped state of the support members by the pair of clamping pieces, and a release means for releasing the clamped state by the fixing means, one of the clamping pieces has a plurality of insertion pins protruding from the clamping surface that are arranged in accordance with the spacing of the through holes, and the other clamping piece has insertion holes on the clamping surface that correspond to the arrangement positions of the plurality of insertion pins, and the protruding length of the insertion pins is configured to be at least longer than the thickness of the support members.

[0010] In addition, in the equipment rack mounting jig having the above-mentioned features, it is preferable that one of the pair of clamping pieces is a base piece and the other is a movable piece, the movable piece is movable along a slide guide that is erected from the base piece as a base point, and the fixing means is a means for restricting movement relative to the slide guide. With such features, the movable piece can be moved along the slide guide to clamp the support member.

[0011] In addition, in an equipment rack mounting jig having the above-described features, the movable piece may be provided with a grip through which the slide guide passes and a lever that can be gripped using the grip as a base point, and gripping the lever causes the movable piece to slide along the slide guide toward the base piece. With this feature, the support member can be clamped simply by gripping the lever while holding the grip, making it possible to install the equipment rack mounting jig with one hand.

[0012] Furthermore, in an equipment rack mounting jig having the above-described features, it is desirable that the release means be provided on the movable piece, so that both the mounting and detachment of the equipment rack mounting jig can be completed by simply operating the movable piece. [Effects of the Invention]

[0013] An equipment rack mounting jig having the above-described characteristics can be easily attached to and detached from the rack (the support members that make up the rack), is stable when attached, and can also be used for a wide range of equipment to be fixed.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of an equipment rack mounting jig of the present invention will be described in detail with reference to the drawings. The rack mounting jig according to the following embodiment is used by clamping and fixing it to support members 110 that constitute rack 100, the details of which will be described later.

[0016] [composition] The rack mounting jig according to this embodiment (hereinafter simply referred to as jig 10) has at least a pair of clamping pieces consisting of a base piece 12 and a movable piece 22. The clamping pieces are elements for clamping the plate pieces that make up the support member 110 in the thickness direction. Note that the support member 110 referred to in this embodiment may be any member that can serve as a support for the rack 100, such as a long plate material or angle bar. In the case of the jig 10 according to this embodiment, the element that serves as the base point for clamping is the base piece 12, and the element that allows it to slide in the opening and closing direction relative to the base piece is the movable piece 22.

[0017] The base piece 12 has a clamping surface 14 that abuts against the support member 110, and the clamping surface 14 is provided with an insertion pin 16, a slide guide 18, and a guide hole 20. The insertion pins 16 are pins to be inserted into a plurality of through holes 112 formed at regular intervals along the longitudinal direction of the support member 110 to be installed. The spacing between the insertion pins 16 may be the same as or a multiple of the spacing between the through holes 112 formed in the support member 110, and at least two pins (ideally three) should be provided. Even a single insertion pin 16 can prevent the jig 10 from slipping down due to a load. On the other hand, if two or more insertion pins 16 are provided, it is possible to prevent the jig 10 from tilting in addition to slipping down due to a load.

[0018] The slide guide 18 is a guide for moving the movable piece 22 in the clamping direction. The slide guide 18 according to the embodiment is a band-shaped flat plate member that stands perpendicular to the clamping surface 14. The guide hole 20 is a through-hole for inserting a guide pin 28 that stands on the movable piece 22. By inserting the guide pin 28 into the guide hole 20, it is possible to prevent the base piece 12 and the movable piece 22 from being misaligned relative to each other.

[0019] The movable piece 22 is an element that moves along the slide guide 18 and sandwiches the support member 110 between itself and the base piece 12. The movable piece 22 is provided with a clamping surface 24, a grip 30, a lever 32, and a release mechanism 34, and these elements move as the movable piece 22 moves. The clamping surface 24 is provided with a hole for inserting the slide guide 18, as well as an insertion hole 26 and a guide pin 28. The insertion hole 26 is an element for inserting the insertion pin 16 that constitutes the base piece 12. By receiving the insertion pin 16 in the insertion hole 26, the insertion pin 16 is supported at both ends, improving stability under load (when the target device 120 is mounted). For this reason, it is preferable that the diameter of the insertion hole 26 has a slight plus tolerance with respect to the insertion pin 16 to minimize wobble. The guide pin 28 is an element for insertion into the guide hole 20 provided in the clamping surface 14 of the base piece 12. By inserting the guide pin 28 into the guide hole 20, it is possible to suppress relative misalignment between the base piece 12 and the movable piece 22.

[0020] The grip 30 is a handle that extends from the movable piece 22 on the side opposite to the clamping surface 24, and is configured so that the slide guide 18 inserted from the clamping surface 24 can be inserted inside.

[0021] The lever 32 is a driving element for moving the movable piece 22 toward the base piece 12. The lever 32 extends from the base of the grip 30 on the movable piece 22 in the direction in which the grip 30 extends, away from the grip 30. The lever 32 configured in this manner acts to push the movable piece 22 toward the base piece 12 by squeezing it while holding the grip 30.

[0022] As shown in FIG. 6, the lever 32 according to this embodiment is formed to have a substantially L-shape and includes a fulcrum O, a force point P, and an action point A. As shown in FIG. 6, two pushing plates 36a and 36b are inserted into the slide guide 18. When viewed from the direction of arrow B in FIG. 6, the relationship between the pushing plates 36a and 36b and the slide guide 18 is as shown in FIG. 7. That is, a gap is created in the height direction between the slide guide 18 and the through holes 36a1 and 36b1 of the pushing plates 36a and 36b. This allows the pushing plates 36a and 36b to be positioned diagonally relative to the slide guide 18 (see FIG. 8). By positioning the pushing plates 36a and 36b diagonally relative to the slide guide 18, the thickness-direction corners located on the upper and lower sides of the through holes 36a1 and 36b1 come into contact with the upper and lower surfaces of the slide guide 18, generating a high frictional force. Additionally, upper end sides 36a2, 36b2 of the pushing plates 36a, 36b contact the action point A of the lever 32, and lower end sides 36a3, 36b3 contact the pressing wall 38 that is part of the movable piece 22. The two pushing plates 36a, 36b arranged in this manner are biased by a biasing means 40 that generates a biasing force toward the clamping surface 24 side, with a part of the grip 30 as a base point.

[0023] With this configuration, when the lever 32 is gripped so that the force point P approaches the grip 30, the action point A of the lever 32 presses the upper end sides 36a2, 36b2 of the pushing plates 36a, 36b, as shown in Fig. 8. With the upper end sides 36a2, 36b2 pressed, the pushing plates 36a, 36b generate friction between the slide guide 18 and the through holes 36a1, 36b1 through which the slide guide 18 passes, and are subjected to the biasing force of the biasing means 40, so that the lower end sides 36a3, 36b3 rotate toward the clamping surface 24, using the upper edges of the through holes 36a1, 36b1 as base points. When the pushing plates 36a, 36b rotate in this manner, the lower end sides 36a3, 36b3 press the pressing wall 38 of the movable piece 22. The movable piece 22 is pressed against the pressing wall 38 by the pushing plates 36a, 36b positioned on the slide guide 18 by frictional force, and slides toward the base piece 12 while compressing the biasing means 40.

[0024] When the lever 32 is released after the movable piece 22 has been slid, the pushing plates 36a and 36b are returned to a position perpendicular to the slide guide 18 by the biasing force of the biasing means 40 and are again pressed against the pressing wall 38. Furthermore, as the pushing plates 36a and 36b are pushed back to their original positions, the lever 32 is pushed back to the open position.

[0025] The release means 34 is an element that plays a role in releasing the lock imposed by the fixing means 42 that prevents the movable piece 22 from being pulled back when the movable piece 22 that has moved along the slide guide 18 is pulled back. The release means 34 is an L-shaped lever that has a fulcrum O1, a force point P1, and a point of action A1, and is arranged to be rotatable around the fulcrum O1.

[0026] The fixing means 42 that prevents the movable piece 22 from being pulled back is a plate that is inserted into the slide guide 18. The shape of the plate is the same as the pushing plates 36a and 36b described above, and its function is also the same. That is, by tilting the plate and pressing the upper and lower edges of the through hole through which the slide guide 18 is inserted against the slide guide 18, a strong frictional force is generated, preventing the movable piece 22 from being pulled back.

[0027] The upper end side of the plate constituting the fixing means 42 abuts against a reference wall 44 provided on the movable piece 22. In this state, the fixing means 42 is pressed toward the clamping surface 24 by the biasing means 46 provided between the fixing means 42 and the movable piece 22, so that the lower end side of the plate constituting the fixing means 42 abuts against the action point A1 of the releasing means 34 in a state inclined toward the clamping surface 24 with the upper end side as the base point. This state of the fixing means 42 is the so-called locked state.

[0028] When the release means 34 presses the force point P1 toward the movable piece 22, the action point A1 presses the lower end side of the fixing means 42. As a result, as shown in Figure 9, the plate surface of the plate that constitutes the fixing means 42 becomes perpendicular to the slide guide 18, reducing the friction that had occurred between them and releasing the lock. Therefore, it becomes possible to move the movable piece 22 away from the base piece 12.

[0029] The jig 10 having such a configuration has mounting surfaces 12a, 22a on both sides of the base piece 12 and the movable piece 22. By providing the mounting surfaces 12a, 22a, which are smooth surfaces, it becomes possible to stably mount the device 120 to be fixed on the mounting surfaces 12a, 22a after the jig 10 is fixed to the rack 100.

[0030] [Actions and Effects] Next, a method of using the jig 10 configured as described above will be described with reference to Figures 10 to 14. First, as shown in Figure 10, the base piece 12 and the movable piece 22 are spaced apart, and the jig 10 is brought close to the support member 110. Next, as shown in Figure 11, the insertion pin 16 of the brought-close jig 10 is inserted into the through-hole 112 of the support member 110. Next, by repeatedly squeezing the lever 32 while holding the grip 30, the movable piece 22 is brought close to the base piece 12, and the support member 110 is sandwiched in the thickness direction between the clamping surface 14 of the base piece 12 and the clamping surface 24 of the movable piece 22 (see Figure 12).

[0031] The same operation is repeated for each of the legs (pillars) of the rack 100, for example, four, and the jig 10 is placed on each pillar member 110. At this time, the placement height of each jig 10 is made to match, as shown in Fig. 14. After the jigs 10 have been placed on all pillar members 110, the device 120 to be fixed to the rack 100 is placed on the placement surface 12a, 22a of the jig 10 and fixed to the through-hole 112 of the pillar member 110 with a bolt via a bracket 114 or the like.

[0032] After the target equipment 120 is fixed with the bolts, the force point P1 of the release means 34 of each jig 10 is pressed to release the lock by the fixing means 42, separating the base piece 12 and the movable piece 22 as shown in Figure 13, and removing it from the rack 100, thereby completing the work.

[0033] With a jig configured as described above, the support member 110 can be clamped and fixed by gripping the lever 32, and the fixed state can be released simply by operating the release means 34. Furthermore, since the insertion pin 16 is inserted into the through-hole 112 of the support member 110, there is no risk of the support member 110 shifting from its installed position even when a load is applied to the mounting surfaces 12a, 22a. This makes attachment and detachment easy, and the jig is stable in the fixed state. Furthermore, since the target device 120 can be placed and fixed on the mounting surfaces 12a, 22a provided on the base piece 12 and the movable piece 22, the jig can be used to fix a variety of target devices 120 (improved versatility). Furthermore, when the jig 10 is provided with mounting surfaces 12a, 22a and the target device 120 is placed on the mounting surfaces 12a, 22a, the fixing holes of the target device 120 or the fixing holes of the brackets 114 for fixing the target device 120 match with the through holes 112 of the support members 110, facilitating the installation and fixing of the target device 120. Furthermore, the jig 10 can be removed simply by pressing the release means 34 to separate the movable piece 22 from the base piece 12, which makes it possible to significantly reduce the time required to install and remove the jig 10 compared to conventional methods.
