Description

According to the present invention, the pillar material can be fixed at a desired height position without using nails or screws, and the weight of the shelf board or the mounted object is effectively applied as a fixing force to the pillar material to cause slippage. It relates to a shelf holder that can be used for placing heavy objects.

When you want to install a shelf board between adjacent pillars, it is generally done by fixing the shelf support to both pillars with nails or screws and erection the shelf board between the shelf supports. However, if nails and screws are used, a separate tool is required for fixing, and when fixing the shelf support, it is troublesome to set the accuracy of the left and right height positions, and the shelf support is removed. In some cases, there is a problem that traces of nails and screws are left on the pillar material.

Therefore, by obtaining a fixing force to the pillar material by using the weight of the shelf board and the mounted object, nails and screws are not required when erection of the shelf board, the erection height can be easily set and adjusted, and the pillar material can be erected. Shelf supports have been proposed that can eliminate the occurrence of damage to the shelves.

In the first example of the conventional shelf support, outer fitting portions bent in a U shape from the metal wire rod forming the shelf material are provided at positions on both sides at the rear end portion of the shelf material, and the outer fitting portion is provided. It has a structure in which a contact piece bent so as to protrude downward is formed in the middle of the front edge, and when the outer fitting part is fitted to each of the pillar materials on both sides and the shelf material is attached, the contact piece is the pillar material. By abutting on the front surface and applying an inclination force that lowers the shelf material side to the outer fitting part with the lower end of the contact piece as a fulcrum by the weight of the shelf board or the mounted object, the trailing edge of the outer fitting part and the lower end of the contact piece The pillar material is sandwiched from the front and back, and the holding force is used to obtain a fixed state of the shelf material with respect to the pillar material (see Patent Document 1).

The shelf support of the second example includes a semi-cylindrical portion provided at the rear portion of the shelf plate and a semi-cylindrical cap member fixed to the open rear surface of the semi-cylindrical portion, and both ends of the semi-cylindrical portion. By fitting the tapered groove provided on the inner surface and the tapered flanges provided on the outer surfaces of both ends of the cap member, the two are joined while holding the pillar material, and the elastic tongue piece provided on the cap member is attached to the pillar material. The structure is such that the shelf board is fixed to the pillar material by pressure contact, and even in the shelf supporter of this second example, an inclined load that lowers the shelf board side due to the weight of the shelf board and the mounted object is applied. It is considered that the pillar material is sandwiched from the front and back between the lower end of the inner circumference of the semi-cylindrical portion and the upper end of the inner circumference of the cap member, and this holding force contributes to fixing the shelf material to the pillar material (see Patent Document 2).

The shelf supports of the third and fourth examples are a semi-cylindrical or U-shaped rear fitting member that circumscribes the rear surface of the pillar material, and a semi-cylindrical or U-shaped rear fitting member provided at the rear end of the shelf board. It is composed of a combination of front fitting members, and has a structure in which wedge grooves are provided on facing surfaces on both front edges of the rear fitting member and wedge plates are provided on opposite outer surfaces on both front edges of the front fitting member. , Insert the wedge plate of the front fitting member into the wedge groove of the rear fitting member externally attached to the pillar material from above, and tighten both fitting members by fitting the wedge groove and the wedge plate to the shelf on the pillar material. The shelves in the third and fourth examples fix the board, and the lower end and rear fitting of the front fitting member are applied by applying an inclined load that lowers the shelf board side due to the weight of the shelf board and the mounted object. The pillar material is sandwiched from the front and back by the upper end of the wearing member, and the shelf material is fixed to the pillar material by this holding and holding force (see Patent Documents 3 and 4).

By the way, in each of the shelf supports as in Patent Documents 1 to 4, the shelf boards can be attached to the desired positions above and below the pillar material without using nails or screws, and the weight and load amount of the shelf boards can be used to determine the shelf support. Although it works as a force to fix it to the pillar material, the shelf support of Patent Document 1 has a U-shaped outer fitting part to the pillar material, so that it is structurally mechanical. Since the strength and fixing strength to the pillar material are weak, the load supporting strength is inferior, and it is not suitable for supporting heavy objects. When a load is applied, the U-shaped open part of the outer fitting part is pushed open, causing vibration, etc. There is a problem that the shelf board slides down due to the action of.

In the shelf support of Patent Document 2, the semi-cylindrical portion and the cap member are joined to hold the pillar material, and the inner peripheral surface of the semi-cylindrical portion is pressed against the pillar material with the elastic tongue piece of the cap member to fix it. As the elastic deterioration of the elastic tongue piece over time, the fixing force to the column material decreases.

In addition, since the semi-cylindrical portion and the cap member are combined and integrated without moving up and down, the pillar material is retightened with respect to fixing the shelf material to the pillar material using the weight of the shelf board or the mounted object. Since it has no function, it cannot be expected to increase the fixing force to the column material.

Furthermore, the semi-cylindrical part and the cap member do not have a vertical position adjustment function in the joint structure of both, and have a structure in which they are fitted in a fixed position and combined to hold the pillar material, so that they are attached to the pillar material. In this state, it becomes difficult to move up and down, and there is an inconvenience that the height of the vertically fixed position cannot be adjusted unless the semi-cylindrical portion and the cap member are completely disassembled.

In the shelf supports of Patent Documents 3 and 4, the rear fitting member and the front fitting member are tightened and joined by fitting the wedge groove and the wedge plate, but the fitting of the wedge groove and the wedge plate is the rear fitting. Since the structure is such that it spreads outward with respect to the tips on both sides of the attachment member, the connection between the wedge groove and the wedge plate does not retighten against the holding of the pillar material, and therefore to the pillar material by retightening. In actual use, when the weight of the shelf board or load is applied, the wedge groove and the spread of the wedge board act outward to open the tips on both sides of the rear fitting member. Therefore, there is a problem that it is not suitable for placing a heavy object because the fixing force to the pillar material is reduced.

Therefore, the subject of the present invention is that the vertical height can be easily adjusted, the weight of the shelf board and the load amount can be effectively acted as a tightening force on the pillar material, and a heavy object can be placed. It is to provide shelf support.

In order to solve the above-mentioned problems, the invention of claim 1 is a load support member 2 in which the arm plate portions 6 facing each other are open and can be externally contacted with a pillar member, and the load support member. to 2, made from the shelf receiving member 3 which circumscribes the column member by attaching to couple arms plate portion 6, the each of the both end portions of the arms plate portion 6 and the shelf support member 3, both arms by fitting from above the shelf support member 3 with respect to the plate portion 6, the shelf support a pair of mating mechanism 4 for coupling the arms plate portion 6 in member 3, the mating mechanism 4, an arm plate It has vertical uneven surfaces 13 and 14 provided on each of the vertical overlapping surfaces formed by fitting the portion 6 and the shelf support member 3, and the uneven surfaces 13 and 14 have wedge-shaped protrusions having different widths at the top and bottom. In the shelf supporter formed by the combination of the jo and the concave that is located between the convex and fits the other convex.
The convex and concave surfaces of the uneven surfaces 13 and 14 provided on the arm plate portion 6 and the shelf receiving member 3 in the fitting mechanism 4 are formed so that the fitting of the convex and the mating concave is further tightened. The vertical shape of the mating concave is reversed, and the wedge shape of the convex and mating recess is formed so as to pull the load supporting member 2 toward the shelf receiving member 3 at the time of fitting. It was done.

The invention of claim 2 is the invention of claim 1, wherein the shelf support member makes linear or dot contact with the outer surface of the pillar material at the lower part of the back surface on the side circumscribing the pillar material. It is designed so that a contact portion is provided.

Here, the load support member and the shelf support member are formed by using, for example, a hard synthetic resin, and a portion of the load support member that sandwiches the pillar material from both sides on the inner peripheral surface exerts a fixing force at the time of pressure contact with the pillar material. In order to increase the load, vertical protrusions and concave grooves are alternately formed on the uneven pressure contact surface, and one of the fitting mechanisms provided on both end arm plates of the load supporting member extends from the tip of the arm plate. A plate having a thickness thinner than that of the arm plate is projected forward in the direction, and an uneven surface is provided on the outer surface of the plate in an inclined shape in which the lower end approaches the arm plate side.

Further, the shelf support member is composed of a joint portion having a length for connecting both arm plates of the load support member and a shelf plate receiving portion provided in a row on the front surface thereof, and is provided with outer plates provided at both ends of the joint portion. A groove into which the plates are fitted is formed between the inner plates, and the other fitting mechanism provided on the inner surface of the outer plate has a structure in which an uneven surface is vertically provided.

Therefore, when both end arm plates of the load support member are joined by the joint portion of the shelf support member, the pillar material is sandwiched from the front and back by the joint portion of the back plate portion of the load support member and the shelf support member, and the weight of the shelf plate or the mounted object is weighted. By adding to the shelf support member, the combination of the uneven surfaces of the fitting mechanism acts to pull the load support member toward the shelf support member side, and a strong fixing force to the pillar material can be obtained.

According to the invention of claim 1, since both arm plates of the load support member are fixed to the pillar material by being joined by the shelf support member, the load support member and the shelf support member are kept connected to the load support member. By simply moving the shelf support member up and down, it can be fixed, adjusted and removed from the pillar material, and the shelf support member can be moved up and down by a simple operation, so it is easy to handle and the vertical height can be easily adjusted. ..

In addition, the fitting mechanism that connects the load support member and the shelf support member has a vertically uneven surface that fits each other, and the load support member is pulled toward the shelf support member side by this uneven surface. Since the weight of the loaded luggage can be effectively acted as a tightening force on the pillar material and a fixing force proportional to the load can be obtained, there is no slipping due to vibration etc., and it is possible to support the loading of heavy objects. Become.

Further, according to the invention of claim 1 , since the uneven surface of the fitting mechanism is further tightened by the fitting of the convex and the mating concaves, the upper and lower parts of the fitting mechanism and the shelf support member are connected. The positional relationship can be stably maintained, and the coupling force between the load supporting member and the shelf support member can be increased according to the increase in the tightening force on the column material.

According to the invention of claim 2 , the shelf support is provided by providing a contact portion that makes linear or point contact with the outer surface of the pillar material at the lower part of the back surface that is the side that contacts the pillar material of the shelf support member. By concentrating the fixing points of the member on the pillar material on the contact portion, the fixing force on the pillar material is improved, and the shelf support member can be reliably fixed at the desired height position of the pillar material. Even when the weight of the shelf board and the load amount are relatively light, it is possible to prevent the shelf support member from slipping off with respect to the pillar material.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 3, since the shelf board b is horizontally erected between the pillars a standing on both sides, the shelf receiver 1 of the present invention is fixed at the same height position of both pillars a. The load support member 2 is externally attached to the pillar material a, and the shelf support member 3 is externally attached to the pillar material a by connecting both ends of the load support member 2. The member 2 and the shelf support member 3 are formed using, for example, a hard synthetic resin, and the shelf support member 3 is fitted from above into both ends of the load support member 2 and both ends of the shelf support member 3. A fitting mechanism 4 is provided to connect both ends of the load support member 2 with the shelf support member 3.

In the case of the figure, the shelf support 1 shows an example corresponding to the square pillar material a, and the load support member 2 is in the same direction at both ends of the horizontally long back plate portion 5 that matches the width of the back surface of the pillar material a.

The inner peripheral surfaces of both arm plate portions 6 facing each other are formed on the concave-convex pressure contact surface 7 in which vertical protrusions and concave grooves are alternately continuous in order to increase the fixing force at the time of pressure contact with the pillar material a. It has become.

The shelf receiving member 3 has a length for connecting the tips of both arm plate portions 6 of the load supporting member 2 to each other, and has a connecting portion 8 that abuts on the front surface of the pillar member a and a shelf provided in series with the front surface thereof. The joint portion 8 is composed of a plate receiving portion 9, and the front plate 8b perpendicular to the horizontal upper plate 8a has an L-shaped cross section, and the shelf plate receiving portion 9 projects forward from the lower edge of the front plate 8b. It is composed of a receiving plate 9a, and side plates 9b provided at both ends at the corners of the receiving plate 9a and the front plate 8b, and holds a shelf plate b into which the end portions are fitted from above.

As shown in FIG. 2A, the shelf support member 3 is in contact with the lower part of the back surface, which is the side circumscribing the front surface of the pillar material a, in a linear or point shape with respect to the front surface of the pillar material a. The part 10 is provided. In the case of the figure, a plurality of square rib plates 10a are provided at positions on the inner corner side of the upper plate 8a and the front plate 8b in the length direction, and the lower end rear portion of each rib plate 10a, for example, a right-angled sharp corner is formed as a pillar material. The contact portion 10 is in contact with the front surface of a in a point shape. For example, the trailing edge or lower edge of each rib plate 10a is connected by a vertical or horizontal plate, and the lower edge or trailing edge of this plate is connected. The structure may be such that the contact portion linearly contacts the front surface of the pillar material a.

The pair of fitting mechanisms 4 for assembling the shelf support member 1 by connecting the arm plate portions 6 of the load support member 2 with the shelf support member 3 have the arm plate portion whose inner surface is at the tip of the arm plate portion 6. A square vertical plate 11 having the same plane as 6 and slightly thinner than the arm plate 6 is provided so as to project forward in the extension direction, and is fitted to both ends of the shelf support member 3 from above on the vertical plate 11. The groove portion 12 to be inserted is formed, and the outer surface of the vertical plate 11 is provided with the concave-convex surface 13 in the vertical direction and the uneven surface 14 in the vertical direction is provided inside the groove portion 12 so as to fit each other.

Specifically, as shown in FIG. 2, at both ends of the shelf receiving member 3, a vertical outer plate 15 and an inner plate 16 are provided so as to form a groove portion 12 in which the vertical plate 11 fits, and the inner surface of the outer plate 15 is provided. The other uneven surface 14 is formed on the outer surface of the vertical plate 11, and one uneven surface 13 is formed on the outer surface of the vertical plate 11 as shown in FIG. The upper surface of the groove 12 is closed by the upper plate 8a and the front surface is closed by the front plate 8b. In the case of the drawing, the height dimension of the inner plate 16 is set to be slightly shorter than that of the outer plate 15, and the groove portion 12 is rear of the outer plate 15. A guide piece 17 having an inclined surface on the inner surface side is projected from the end portion so that the groove portion 12 can be smoothly fitted into the vertical plate 11.

As shown in FIG. 1B, one of the uneven surfaces 13 provided on the outer surface of the vertical plate 11 is formed by a combination of a wedge-shaped convex groove 13a and a concave groove 13b located between the convex grooves 13a. Similarly, the concave-convex surface 14 of the outer plate 15 is also formed by a combination of a wedge-shaped convex groove 14a and a concave groove 14b located between the convex grooves 14a, and as shown in FIGS. 1 (b) and 2 (c), On the concave-convex surfaces 13 and 14 of the vertical plate 11 and the outer plate 15, the shapes of the protrusions 13a and 14a in the vertical direction are reversed, and the protrusions and the mating wedges are fitted together, that is, the protrusions 13a and the recesses 14b. , Convex 14a and concave 13b are retightened, and as shown in FIG. 1B, one of the uneven surfaces 13 formed on the vertical plate 11 has an arm plate portion at the lower end thereof. As shown in FIG. 2C, the other uneven surface 14 provided on the inner surface of the outer plate 15 becomes vertical, and the load supporting member 2 is placed on the shelf receiving member at the time of fitting the outer plate 15 in an inclined shape approaching the side of 6. It is designed to pull 3 to the side.

In the pair of uneven surfaces 13 and 14, when the fitting mechanism 4 is connected by making the uneven surfaces 13 formed on the vertical plate 11 inclined, the shelf support member 3 is attached to the front surface of the pillar member a. The groove portion 12 can be inserted into the vertical plate 11 at a slight distance, and the shelf support member 3 can be easily handled. Further, in the case of the illustration, the pair of uneven surfaces 13 and 14 have a structure having two convex grooves 13a and 14a, but the number of convex grooves can be arbitrarily selected.

Further, in the case of the illustration, the shelf support 1 corresponds to the square pillar member a, but the back plate portion 5 and the both arm plate portions 6 of the load support member 2 are formed into a continuous flat semicircle. Then, it may be possible to fix it to the circular pillar material.

The shelf support 1 of the present invention has the above-described configuration, and the shelf support 1 is fixed to the pillar a in order to install the shelf board b between the pillars a on both sides that stand upright facing each other. First, the load support member 2 is externally fitted and pressed against the pillar material a from the back surface side, and the shelf plate b of the pillar material a is held at a height position where it is desired to be erected with one hand. Here, the front surface of the pillar material a is a surface facing the mating pillar material, and the back surface is a surface opposite to the front surface. Further, in order to hold the pressing position of the load supporting member 2 against the pillar material a, a headed pin having a thin shaft may be fixed to the back surface of the pillar material a, and the back plate portion 5 may be supported by the head. ..

In the load supporting member 2, the back plate portion 5 is in contact with the back surface of the pillar material a, and the uneven pressure contact surfaces 7 on the inner surface of both arm plate portions 6 are in contact with both side surfaces of the pillar material a and project at the tip thereof. The vertical plate 11 is in a state of protruding forward with respect to the front surface of the pillar member a.

Next, the shelf support member 3 held horizontally by the other hand is placed so that both ends of the joint portion 8 are located on the upper portions of both vertical plates 11 with the back surface of the joint portion 8 facing the front surface of the pillar member a. The groove portion 12 at the end is fitted into the vertical plate 11 from above while facing the shelf receiving member 3, and the uneven surface 13 provided on the outer surface of the vertical plate 11 is provided on the inner surface of the outer plate 15. 14 is engaged, the tips of both arm plate portions 6 of the load support member 2 are connected by the joint portion 8 of the shelf support member 3, and the shelf support member 3 is pushed down in this state.

Since the lower end of the uneven surface 13 provided on the outer surface of the vertical plate 11 is inclined so as to approach the arm plate portion 6, the groove portion 12 is fitted into the vertical plate 11 to join the pair of uneven surfaces 13 and 14. In the initial stage, the shelf support member 3 can be started in a state slightly separated from the front surface of the pillar material a, and since the pillar material a does not get in the way, the fitting work can be smoothly performed, and the shelf support member 3 is further lowered. As a result, since the uneven surface 13 of the vertical plate 11 is inclined, the shelf support member 3 approaches the front surface of the pillar material a, and the upper and lower total lengths of both the uneven surfaces 13 and 14 are fitted to each other, and the upper plate 8a is vertically formed. Immediately before contacting the upper end of the plate 11, the contact portion 10 provided on the back surface of the shelf support member 3 at the lower end portion on the back surface side of the joint portion 8 contacts the front surface of the pillar member a.

When a pushing force is further applied to the shelf receiving member 3, the contact portion 10 is pressed against the front surface of the pillar member a, so that both uneven surfaces 13 and 14 are tightly coupled to each other, and the shelf is held with the contact portion 10 as a fulcrum. The rotational force in the direction of separating the receiving member 3 from the front surface of the pillar material a acts to pull the load support member 2 toward the pillar material a, whereby the back plate portion 5 of the load support member 2 acts. The both arm plate portions 6 are pressed against the back surface of the pillar material a, and the concave-convex pressure contact surface 7 on the inner surface thereof is pressed against the side surface of the pillar material a by being pulled toward the front surface side of the pillar material a. On the other hand, the load supporting member 2 is fixed, and at the same time, the shelf receiving member 3 is fixed to the pillar material a by pressing the contact portion 10 against the front surface of the pillar material a in a point-like or linear manner, and the pillar material a is predetermined. The shelf support 1 can be fixed at the height position.

In fixing the shelf support member 1, the load support member 2 and the shelf support member 3 are separate members, and the shelf support member 3 can be moved up and down with respect to the load support member 2. Therefore, the shelf support member 1 is fixed. If the height position adjustment moves the shelf support member 3 slightly upward and the pressure contact of the contact portion 10 to the front surface of the pillar material a is released, the load support member 2 can be moved up and down the pillar material a. The fixed position can be easily adjusted while the load support member 2 and the shelf support member 3 are still connected.

In this way, if the shelf receiving tool 1 is fixed at the same height position of both pillar members a and both ends of the shelf board b are placed on the receiving plate 9a of the shelf receiving member 3 of both shelf receiving tools 1. The end of the shelf board b is held by the receiving portion 9, and the shelf plate b can be erected horizontally between the two shelf receiving tools 1.

The weight of the shelf board b and the weight of the load on the shelf board b described above are applied to the receiving plate 9a of the shelf board receiving portion 3, but are in contact with the upper surface of the receiving plate 9a of the shelf receiving member 3. Since the portion 10 is at substantially the same height or at a position slightly lower, the weight applied to the shelf plate b and the load receiving plate 9a is such that the shelf receiving member is inclined forward with the contact portion 10 as a fulcrum. As a result, the pressure contact force of the contact portion 10 to the front surface of the pillar material a and the force of pulling the load supporting member 2 toward the front surface side of the pillar material a increase, so that the pillar material of the shelf board receiving member 3 Since the fixing force with respect to a is increased and the fixing force proportional to the load is obtained, the situation where the shelf board receiving member 3 slips down does not occur.

Further, in order to remove the shelf board b and remove the shelf board receiving tool 1 from the pillar material a, the shelf board receiving member 3 may be pushed up against the load supporting member 2, and the shelf board receiving member to which the pushing force is applied is applied. Since 3 rises in the direction away from the front surface of the pillar material a along the inclined uneven surface 13 of the vertical plate 11, the contact portion 10 is separated from the front surface of the pillar material a, and the uneven surfaces 13 and 14 If the groove portion 12 is pulled out from the vertical plate 11 by breaking the connection, the shelf plate receiving member 3 and the load supporting member 2 may be separated, and the load supporting member 2 may be removed from the pillar member a. Since the support member 2 and the shelf board receiving member 3 can be fixed by simply holding the pillar material a in an externally fitted shape, the operation of attachment and detachment is easy, and after removal, traces of screws and nails are left on the pillar material a. There is nothing left.
