Description

Technical Field

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

Background Art

[0002] Equipment such as transmission devices installed in business equipment is generally arranged and fixed by stacking multiple stages on a dedicated rack. Since the arrangement forms of the equipment vary widely, there are no shelves in the rack, and the equipment to be fixed is directly fixed to a member (such as an angle member) that constitutes a support column. Therefore, conventionally, a method has been adopted in which a mounting rail is temporarily fixed to the support column member in advance, and then the equipment to be fixed is placed on the rail and the support column member and the equipment to be fixed are fixed. However, the temporary fixing of the mounting rail is also performed by bolting, similar to the fixing of the equipment to be fixed. Therefore, as the number of equipment to be arranged and fixed increases, the time required for attaching and detaching the rail itself becomes extremely long, which has also been a factor in prolonging the construction period.

[0003] In view of such a situation, jigs as disclosed in Patent Document 1 and Patent Document 2 have been proposed. The jig disclosed in Patent Document 1 includes a base portion arranged along the plate surface of a support column member provided with 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-shaped placement portion provided in parallel with the insertion portion with the base portion as a reference point.

[0004] The jig having such a configuration constitutes a temporary placement base for the equipment to be fixed by inserting the insertion portion into the through hole of the support column member with the placement portion positioned on the upper surface. With a jig having such a configuration, the structure is simple, and attachment and detachment are easy, enabling rapid work. However, the arrangement form of the jig disclosed in Patent Document 1 only involves inserting the insertion portion into the through hole, so there remains a concern about stability, and there is a problem that the risk is high when mounting expensive equipment.

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

[0006] With this type of jig, a stable support can be achieved simply by hooking the claws into the through holes. Furthermore, after the equipment to be fixed is secured, the engagement of the fixing bar can be released by moving the movable bar and retracting it from the bottom of the equipment. However, since the jig disclosed in Patent Document 2 supports the equipment to be fixed at a single point, there is a risk of damage to the underside of the equipment when supporting heavy equipment, and the types of equipment that can be supported may be limited.

[0008] Therefore, the present invention aims to solve the above problems and provide a rack-mounting jig for equipment that is easy to attach and detach, stable, and highly versatile for use with equipment. [Means for solving the problem]

[0009] The equipment rack mounting jig according to the present invention for achieving the above objective is a jig used when mounting target equipment to an equipment mounting rack composed of a support member having a plate surface with a plurality of through holes formed at regular intervals along the longitudinal direction, and comprises a pair of clamping pieces having a clamping surface for clamping the support member and a mounting surface for temporarily placing the target equipment at a position that becomes the upper surface when the support member is clamped, a fixing means for maintaining the clamping state of the support member by the pair of clamping pieces, and a release means for releasing the clamping state by the fixing means, wherein one of the clamping pieces has a plurality of insertion pins protruding from the clamping surface arranged in accordance with the spacing of the through holes, and the other clamping piece has insertion holes on the clamping surface corresponding to the arrangement positions of the plurality of insertion pins, and the length of the protruding insertion pins is configured to be at least longer than the thickness of the support member.

[0010] Furthermore, in a rack-mounting jig for equipment having the above-described features, the pair of clamping pieces may have one clamping piece as a base piece and the other clamping piece as a movable piece, the movable piece may be made to move along a slide guide erected with the base piece as the pivot point, and the fixing means may be a means of restricting movement relative to the slide guide. With these features, the support member can be clamped by moving the movable piece along the slide guide.

[0011] Furthermore, in a jig for mounting equipment racks having the above-described features, the movable piece is provided with a grip through which the slide guide is inserted, and a lever that allows gripping using the grip as a pivot point. By gripping the lever, the movable piece is slid along the slide guide toward one side of the base. With these features, the support member can be clamped simply by gripping the lever while holding the grip, making it possible to install the equipment rack mount jig with one hand.

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

[0013] A rack-mounting jig with the above-described features allows for easy attachment and detachment to the rack (the support members that make up the rack), provides stability in the mounted state, and enhances versatility for the equipment being mounted. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the jig for equipment rack mounting of the present invention will be described in detail with reference to the drawings. Note that the rack mounting jig according to the following embodiments is used by being sandwich-fixed to a support member 110 that constitutes a rack 100, the details of which will be described later.

[0016] [Configuration] The rack mounting jig (hereinafter simply referred to as jig 10) according to the present embodiment has at least a pair of sandwiching pieces composed of a base piece 12 and a movable piece 22. The sandwiching pieces are elements for sandwiching a plate piece constituting the support member 110 in the thickness direction. Note that the support member 110 referred to in the present embodiment may be any member that can serve as a support of the rack 1 hundred, such as a long plate material or an angle material. In the case of the jig 10 according to the embodiment, the element serving as a base point during sandwiching is the base piece 12, and the element enabling sliding in the opening and closing direction with respect to the base piece is the movable piece 22.

[0017] The base piece 12 has a clamping surface 14 that contacts 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 pin 16 is a pin for inserting into a plurality of through holes 112 that are formed at regular intervals along the longitudinal direction of the support member 110 to be installed. The spacing of the insertion pins 16 should match or be a multiple thereof of the spacing of the through holes 112 provided in the support member 110, and it is preferable to have at least two pins (ideally three). Even with only one insertion pin 16, it is possible to prevent the jig 10 from sliding down due to the 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 sliding down due to the load.

[0018] The slide guide 18 is a guide for moving the movable piece 22 along the clamping direction. The slide guide 18 according to this embodiment is a strip-shaped flat plate member and is erected perpendicular to the clamping surface 14 as the base point. The guide hole 20 is a through hole for inserting a guide pin 28 erected in the movable piece 22, and by inserting the guide pin 28 through the guide hole 20, relative displacement between the base piece 12 and the movable piece 22 can be suppressed.

[0019] The movable piece 22 moves along the slide guide 18 and is an element for clamping the support member 110 between itself and the base piece 12. The movable piece 22 has a clamping surface 24, as well as a grip 30, a lever 32, and a release mechanism 34, and these elements move along with the movement of the movable piece 22. 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 held in place by both sides, which improves stability under load (when the fixed equipment 120 is mounted). For this reason, the diameter of the insertion hole 26 should have a slightly positive tolerance relative to the insertion pin 16 to minimize play. The guide pin 28 is an element for inserting into a 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, relative displacement between the base piece 12 and the movable piece 22 can be suppressed.

[0020] The grip 30 is a handle that extends on the side of the movable piece 22 opposite to the clamping surface 24, and is configured to allow the slide guide 18, which is inserted from the clamping surface 24, to pass through its interior.

[0021] The lever 32 is a drive 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 of extension of the grip 30 and away from the grip 30. With this configuration, when the lever 32 is gripped while holding the grip 30, it pushes the movable piece 22 toward the base piece 12.

[0022] As shown in Figure 6, the lever 32 according to this embodiment is formed to have a substantially L-shaped body and is equipped with a fulcrum O, a point of force application P, and a point of application A. As shown in Figure 6, two pushing plates 36a and 36b are inserted through the slide guide 18. When the relationship between the pushing plates 36a and 36b and the slide guide 18 is viewed from the direction of arrow B in Figure 6, it takes the form shown in Figure 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. For this reason, the pushing plates 36a and 36b can be positioned diagonally to the slide guide 18 in the plane direction (see Figure 8). By positioning the pushing plates 36a and 36b diagonally to the slide guide 18, the thickness direction corners located on the upper and lower edges 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. Furthermore, the upper ends 36a2 and 36b2 of the pushing plates 36a and 36b contact the point of action A of the lever 32, while the lower ends 36a3 and 36b3 contact the pressing wall 38, which is part of the movable piece 22. The two pushing plates 36a and 36b, arranged in this manner, are biased by a biasing means 40 that generates a biasing force directed toward the clamping surface 24, with a part of the grip 30 as the pivot point.

[0023] With this configuration, when the lever 32 is gripped so that the point of force P is brought close to the grip 30, the point of action A of the lever 32 will press against the upper ends 36a2 and 36b2 of the pushing plates 36a and 36b, as shown in Figure 8. The pushing plates 36a and 36b, with their upper ends 36a2 and 36b2 pressed against them, generate friction between the slide guide 18 and the through holes 36a1 and 36b1 through which the slide guide 18 is inserted, and are also receiving a biasing force from the biasing means 40, so that the lower ends 36a3 and 36b3 rotate towards the clamping surface 24 with the upper edges of the through holes 36a1 and 36b1 as the pivot point. When the pushing plates 36a and 36b rotate in this way, the lower ends 36a3 and 36b3 will press against the pressing wall 38 of the movable piece 22. The movable piece 22, which is pressed against the pressing wall 38 by the pushing plates 36a and 36b positioned on the slide guide 18 by frictional force, slides toward the base piece 12 while compressing the biasing means 40.

[0024] After sliding the movable piece 22, when the lever 32 is released, 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 pressed against the pressing wall 38 again. In addition, the lever 32 is pushed back to the released position as the pushing plates 36a and 36b are pushed back to their original positions.

[0025] The release mechanism 34 is an element that plays a role in releasing the lock imposed by the fixing mechanism 42, which prevents the movable piece 22 from being pulled back when it has moved along the slide guide 18. The release mechanism 34 is an L-shaped lever with a fulcrum O1, a point of force application P1, and a point of application A1, and is rotatably positioned with the fulcrum O1 as the base point.

[0026] The fixing means 42 that prevents the movable piece 22 from being pulled back is a plate inserted through the slide guide 18. The shape of the plate is the same as that of 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 of the plate constituting the fixing means 42 is in contact with the reference wall 44 provided on the movable piece 22. In this state, the biasing means 46 provided between the fixing means 42 and the movable piece 22 presses it toward the clamping surface 24, causing the lower end of the plate constituting the fixing means 42 to contact the point of action A1 of the release means 34 while tilted toward the clamping surface 24 with the upper end as the pivot point. In the fixing means 42, this state is what is known as the locked state.

[0028] The release mechanism 34 pushes the point of force P1 toward the movable piece 22, causing the point of application A1 to press against the lower end of the fixing mechanism 42. As a result, as shown in Figure 9, the plate surface of the fixing mechanism 42 becomes perpendicular to the slide guide 18, reducing the friction between them and releasing the lock. Therefore, it becomes possible to move the movable piece 22 away from the base piece 12.

[0029] In the jig 10 having this configuration, mounting surfaces 12a and 22a are provided on both sides of the base piece 12 and the movable piece 22. By providing the smooth mounting surfaces 12a and 22a, it becomes possible to stably place the equipment 120 to be fixed on the mounting surfaces 12a and 22a after fixing the jig 10 to the rack 100.

[0030] [Effects / Effects] Next, with reference to Figures 10 to 14, the method of using the jig 10 configured as described above will be explained. First, as shown in Figure 10, the base piece 12 and the movable piece 22 are separated, 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 closer to the base piece 12, and the support member 110 is clamped in the thickness direction by 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 process is repeated for the number of legs (support columns) of the rack 100, for example, four, to place the jig 10 on each support column member 110. At this time, the placement height of each jig 10 should be the same, as shown in Figure 14. After placing the jig 10 on all the support column members 110, the equipment 120 to be fixed to the rack 100 is placed on the mounting surfaces 12a and 22a of the jig 10, and bolted to the through holes 112 of the support column members 110 via brackets 114, etc.

[0032] After bolting the equipment to be fixed 120, the effort 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 them from the rack 100, thereby completing the work.

[0033] With this type of jig, 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 it shifting from its installation position even when a load is applied to the mounting surfaces 12a and 22a. Therefore, it is easy to attach and detach, and is stable when fixed. In addition, since the equipment to be fixed 120 can be placed and fixed on the mounting surfaces 12a and 22a provided on the base piece 12 and the movable piece 22, it can be used to fix various types of equipment 120 (improved versatility). Furthermore, by providing mounting surfaces 12a and 22a on the jig 10 and placing the equipment to be fixed 120 on the mounting surfaces 12a and 22a, the fixing holes of the equipment to be fixed 120, or the fixing holes of the bracket 114 for fixing the equipment to be fixed 120, coincide with the through holes 112 of the support member 110, making it easy to install and fix the equipment to be fixed 120. Moreover, removing the jig 10 only requires pressing the release means 34 to separate the movable piece 22 from the base piece 12, thus significantly reducing the time required for installing and removing the jig 10 compared to conventional methods.
